ITEM 1.  BUSINESS.

         This Business section contains forward looking statements that involve
uncertainties. Actual results could differ materially from those in the forward
looking statements due to a number of uncertainties, including, but not limited
to those discussed below and in "Management's Discussion and Analysis of
Operations - Uncertainties Relating to Forward Looking Statements."

         CORPORATE HISTORY

         Nematron Corporation ("Nematron" or the "Company") was incorporated in
Michigan in October, 1983. In 1986, the Company became a wholly-owned subsidiary
of Interface Systems, Inc. ("Interface"). On February 26, 1993, the Company
became an independent publicly-traded company as a result of a spin-off from
Interface, which was effected by the distribution of 100% of the shares of the
Company on a pro rata basis to Interface's shareholders.

         During the year ended September 30, 1995, the Company completed two
acquisitions, the merger of Imagination Systems, Inc., a Virginia corporation
("Imagination"), into the Company, and the merger of Universal Automation, Inc.
("UAI"), into the Company's wholly-owned subsidiary, NemaSoft, Inc.
("NemaSoft").

         During the year ended September 30, 1996, the Company formed a new
wholly-owned subsidiary, Imagination Systems, Inc., a Michigan corporation
("ISI"), which remained a shell company until 1997.

         During the year ended September 30, 1997, the Company completed two
acquisitions, the merger of Intec Controls Corp. into the Company's wholly-owned
subsidiary, NemaSoft, and the merger of Virtual-Time Software, Inc. into ISI.

         The Company's principal executive offices are located at 5840 Interface
Drive, Ann Arbor, Michigan, and its telephone number is (734) 214-2000.


         GENERAL

         Nematron designs, manufactures and markets factory automation products,
including computer hardware and software products. Its industrial computers and
terminals are called Industrial WorkstationsTM, which are "ruggedized" computers
with built-in displays, keyboards or other forms of operator input. Industrial
Workstations are used by operators in industrial processing and in factory floor
environments to monitor and control machine and cell level operations.
Nematron's software products, which have been sold under the trade names of
OpenControl(TM), Hyperkernel(TM), Paragon(TM), FloPro(R), and PowerVIEW(TM), are
sold to industrial users for operator interface, direct machine control and
supervisory control, and its AutoNet(TM) software product is used in test and
measurement environments.

         The primary focus of Industrial Workstations is on applications where
the extremes of temperature, shock and vibration, high humidity, airborne
contaminants and physical abuse or hard use require the use of equipment that
has been specially designed to operate more reliably than commercial grade
equivalents. The Company's industrial computer products are used in industrial
manufacturing and process automation, specifically relating to operator-machine
interface and direct machine control applications. The Company incorporates
electronic technology and software in its Industrial Workstation products to
satisfy a broad variety of customer applications. The applications may range
from the replacement of traditional hardwired push buttons, lights and gauges
that can be used with a single machine or local process, to advanced industrial
computer-based systems that provide supervisory control, direct control and
networking capabilities over a large number of machines.

         The Company has six main software products used in the industrial and
factory automation workplace, all of which were developed by the Company or
acquired. These products are marketed under the trade names OpenControl(TM),
Hyperkernel(R), Paragon(TM), FloPro(R), PowerVIEW(R) and AutoNet(TM).
Additionally, most of the Company's Industrial Workstations contain proprietary
software embedded in the products as firmware which is not 



                                      -2-
<PAGE>   3

sold separately. All six shrink-wrap products can be run on Nematron's computers
or those of most other manufacturers.

         The Company's OpenControl software product allows operators to leverage
PC-based software packages, such as Windows NT and many popular Supervisory
Control and Data Acquisition ("SCADA") and Man-Machine Interface ("MMI")
programs. OpenControl allows the use of standard networking products and
connectivity to the Internet or corporate-wide Intranet systems using a modular
approach for open control architecture applications. Hyperkernel allows software
developers to integrate highly deterministic real-time applications into the
Microsoft's Windows NT operating system and enables devices such as robots,
process controllers and motion control systems to be configured as application
servers on any standard network system. The Company's Paragon software product
is a SCADA package which regulates control and management of process
information. Paragon was developed by Intec, which the Company acquired through
a merger of Intec into the Company's wholly-owned NemaSoft subsidiary in March,
1997. The Company's FloPro software product is a flowchart programming and
direct machine control software product developed by UAI, which the Company
acquired through a merger of UAI into a wholly-owned subsidiary in September,
1995. The Company's PowerVIEW product, first released by the Company in 1996, is
a powerful and comprehensive 32-bit Windows NT and Windows 95-based application
development system for factory floor operator interface applications. The
Company's AutoNet software product is a test and measurement server which allows
for data acquisition and real time processing of data and for performing
multiple functions at high speed while graphically displaying such real time
information through a wide variety of configurable graphic instruments, trends
and Cartesian plots. AutoNet was developed by Imagination, which the Company
acquired by merger in March, 1995.

         The Company had six primary locations, three of which were closed
subsequent to September 30, 1998.

         The Company's headquarters are in Ann Arbor, Michigan and employees
located there are responsible for product development, administration, finance,
accounting, personnel, computer manufacturing, customer service, corporate
purchasing, corporate quality, corporate marketing, corporate-wide sales and
international business development.

         The Company's software development and software manufacturing for its
Nematron and NemaSoft products were conducted primarily at its Foxboro,
Massachusetts and Virginia Beach, Virginia offices, although certain development
activities were also performed at its Santa Clara, California and Hilliard, Ohio
facilities. Subsequent to September 30, 1998, the Virginia, Ohio and California
offices were closed, and all software development activities were transferred to
Foxboro, Massachusetts. Software engineers and other employees located at this
facility are responsible for software product development, enhancement,
maintenance, and reproduction of shrink-wrapped software.

         The Company's sales operations for the European marketplace are
conducted in Chichester, United Kingdom, through Nematron, Ltd., which was a
wholly-owned subsidiary of Intec which the Company acquired in March, 1997.
Located south of London, its principal functions are European sales,
distribution management, application engineering and customer service. Nematron,
Ltd. is primarily operated as a cost center since allocation of gross product
margins and operating and administrative expenses cannot be reasonably allocated
to that entity or by region.



PRODUCTS, MARKET AND COMPETITION

         COMPUTERS AND HARDWARE PRODUCTS

         The Company designs and manufactures operator terminals for reliable
performance in harsh industrial environments. Each operator terminal provides a
display that shows the status of the process and a keyboard or a touch screen
that allows personnel to control the process. These terminals all come in a
rugged package that withstands extremes of temperature, humidity, vibration,
shock, and electrical interference.

         The Company offers a variety of Industrial Workstations to the
industrial automation marketplace. Each product class includes a range of
display options, prices, and capabilities.


                                      -3-
<PAGE>   4

         Virtually all of the Company's smaller and newer products use "flat
panel" displays. Popularized by laptop personal computers, flat panels offer
considerable space savings over CRTs with increased reliability. These products
also provide immunity to shock, vibration, and electromagnetic interference.
They are particularly well suited for applications with hazardous environments
such as chemical plants, and in the presence of high electrical currents, such
as in aluminum and steel processing applications. In the near future, management
intends to convert virtually all of the Company's products to flat panel
technology.

         While price and features can be important factors in a customer's
purchase decision, reliability consistently ranks the highest. As a result, the
Company expends significant effort on design verification and testing of new
products and purchased subassemblies. In addition, management believes the
Company is able to price its products competitively because of their higher
quality, and hence lower warranty and repair work is required to be performed
after the sale.

         CHARACTER-BASED PLC WORKSTATIONS AND REMOTE MESSAGE UNIT PRODUCTS

         Character-based programmable logic controller ("PLC") workstations and
remote message unit products economically replace as few as five
electro-mechanical push buttons, while also providing message display and alarm
annunciation functions. All products in this class include flat panel displays.
The Company internally developed the proprietary software for the products in
the lower price range of this class of product. Most of these products are used
with small PLCs for simple machine control, such as packaging equipment and
small fabricating machines. Products in this class range in price from less than
$500 to $2,000.

         Most of the Company's competitors in this segment are small companies
with limited resources and market share. A few competitors, such as
Allen-Bradley and Eaton IDT, have substantially greater resources than the
Company, and offer competitive products in the upper end of the price range.

         Sales of low-end products in each of 1998 and 1997 amounted to less
than 10% of consolidated revenue. The Company expects a growth rate of
approximately 5% in this market segment in the next year, largely because
industry analysts project similar growth in the small PLC market. To participate
in this growth, the Company plans to maintain a modest level of product
development effort to enhance existing products.

         INDUSTRIAL GRAPHICS TERMINALS AND PROGRAMMABLE OPERATOR INTERFACE
PRODUCTS

         Industrial graphics terminals and programmable operator interface
products include both CRT displays and keyboards. These products utilize the
Company's proprietary hardware and software designs, which support either remote
terminal operation with an intelligent host, or fully programmable operation to
support PLC operator interface applications.

         Because several dozen large and small companies offer competing
products in this market, competition is intense. Every major PLC company
competes in this market, either with its own designs or with private-labeled
products. Significant competitors include Allen-Bradley, Siemens and Eaton IDT.

         Sales of industrial graphics terminals and programmable operator
interface products in each of 1998 and 1997, amounted to less than 10% of
consolidated revenue. The Company expects a decrease of approximately 10% per
year in this market segment due to the anticipated availability of more
sophisticated technology at lower costs.

         INDUSTRIAL PC PRODUCTS AND INDUSTRIAL CONTROL COMPUTER PRODUCTS

         The 5000, 6000 and 7000 series of Industrial Control Computers ("ICCs")
were designed and developed by the Company in 1995 and 1996. ICC-5/6/7000 
products offer a Pentium 133, Pentium/MMX 200 MHz, Pentium/MMX 233 MHz or
Pentium II 333 MHz processors. They are shipped with display options from 10.4"
to 13.8" and a choice of motherboards featuring PCI/ISA bus architecture. The
front panels of these units have integrated keypads and are rated UL Type 4
(watertight) construction. Each of these models is UL safety rated and is
certified to the CE Mark. Many of the ICC products are also "bundled" with the
Company's OpenControl and Paragon software products. These units range in price
from $4,800 to $13,000, varying primarily on the choice of display and bundled
software.

         The 500i, 600i and 700i series of Industrial Control Computers ("ICIs")
were designed and developed by



                                      -4-
<PAGE>   5
the Company in 1998. ICI-5/6/700 products offer Pentium 133, Pentium/MMX 200
MHz, or Pentium/MMX 233 MHz processors with an ISA passive backplane
architecture. They are shipped with display options from 10.4" to 13.8" and have
the same ratings as the ICC-5/6/7000 series. These units range in price from
$4,800 to $10,000, varying primarily on the choice of display and bundled
software.

         The FlexBox(TM) modular rack-mount or bench-top PC provides Intel 80X86
architecture with processors ranging from Pentium 133 to Pentium II 333 MHz
processors. These computers are based on the same PCI/ISA motherboard
technologies offered in the ICC-5/6/7000 series. These modular computers are
often integrated into a system which includes the Nematron MON-500 product, a
flat panel monitor with UL Type 4 front panel. FlexBox products range in price
from $2,400 to $8,000 and the MON-500 ranges from $3400 to $4000 depending upon
hardware and software options.

         Sales of these products in 1998 and 1997 amounted to 33% and 60%,
respectively, of consolidated revenue. The Company expects that revenue from
this product category will represent approximately 50% of revenues in fiscal
1999.

         Management believes that while operator interface products will
eventually migrate to PC-based control and operator interface solutions that
eliminate the PLC, the migration will not be complete for many years, and the
market for industrial PC products will expand significantly. In response to this
evaluation of the market, the Company will place substantial emphasis on further
enhancements to Industrial PC and ICC products as cost effective replacements
for existing, lower functionality, industrial workstations that complement,
rather than replace, PLCs.

         Many competitors participate in the industrial PC product market, most
notably IBM, Allen-Bradley, and Siemens. Many segments in this market are highly
price-sensitive, especially in environments where commercial-grade products
perform adequately. As the market expands, numerous competitive offerings will
probably appear, putting downward pressure on prices and gross profit margins.
The Company intends to continue providing industrial PC products for reliable
operation in harsh environments.


         COMPUTER HARDWARE PARTS AND SERVICE

         The Company maintains an inventory of spare parts and service stock and
dedicates approximately 15 service technicians and support personnel whose
functions include technical advice regarding product applications and service
and repair of returned computer and other hardware. With the increasing number
of units in service in the marketplace due to the products' wide acceptance and
long life, the shipment of spare parts and performing repair service on
out-of-warranty product continues to be a significant part of the business.



         SOFTWARE PRODUCTS

         The software products described below, all of which were acquired or
developed by the Company since 1995, represent the cornerstone of the Company's
shift in its strategic focus. Prior to 1995, the Company relied solely on sales
of Industrial Workstation products. Since 1995 the Company's strategy has been
to position itself as a high value-added provider of bundled industrial PC
hardware and Microsoft operating system-based software solutions. With the
acquisition of the following software products, plus the continued enhancement
of existing products and the development of new software products, the Company
is positioning itself to become a leading supplier of industrial automation
software. The Company will attempt to use its software and proven reliable PC
hardware to help drive the factory automation industry from PLC to PC based
control due to the superior technical features of PC based control over PLC
technology.

         The Company's six main software products are used in the industrial and
factory automation workplace. Additionally, most of the hardware products
discussed above contain proprietary software embedded in the products as
firmware which is not sold as a separate product. All six shrink-wrap products
may be run on Nematron's computers or on computers of most other manufacturers.



                                      -5-
<PAGE>   6

         Sales of software products, including associated support, training and
maintenance agreements, amounted to 24% and 16% of the Company's consolidated
revenue in 1998 and 1997, respectively. The Company expects that revenue from
software products will represent approximately 25% of revenues in fiscal 1999.

         OPENCONTROL(TM)

         The Company's software product suite for open architecture, direct
control of machines is called OpenControl(TM). OpenControl allows operators to
leverage PC-based software packages, such as Windows NT and many popular
Supervisory Control and Data Acquisition ("SCADA") and Man-Machine Interface
("MMI") programs, including the Company's proprietary Paragon SCADA product and
its PowerVIEW MMI product. OpenControl allows the use of standard networking
products and connectivity to the Internet or corporate-wide Intranet systems.
OpenControl provides a modular approach for open control architecture
applications. The product is comprised of a series of Visual Programming
languages for control, the FloPro for Windows NT run-time control engine, and
independent Device Network I/O servers. FloPro for Windows NT is OpenControl's
run-time engine, and is a 32-bit version of the original field-proven FloPro
technology described below. FloPro for Windows NT is several times faster than
its DOS-based predecessor and is based on the Hyperkernel real-time Windows NT
technology. A variety of device networks and legacy PLC I/O systems are
supported.

         HYPERKERNEL(R)

         Hyperkernel allows software developers to integrate highly
deterministic real-time applications into the Microsoft's Windows NT operating
system and enables devices such as robots, process controllers and motion
control systems to be configured as application servers on any standard network
system. The Hyperkernel product includes features such as high speed timers;
memory management; interrupt handlers; inter-process communication; file system
services; and task scheduling and prioritization. By using a standardized
development environment like Microsoft C and Visual C++, significant reductions
in software development time may be achieved.

         The technology provides true client/server capabilities for complex
software applications. The Hyperkernel RTSS for the Windows NT operating system
utilizes a sophisticated message-passing architecture for inter-process
communications, which is the key difference between Hyperkernel and similar
products developed to operate under DOS or Microsoft's Windows 3.1 operating
systems.

         Traditionally, many developers have used custom or proprietary
operating systems and tools to gain high-speed determinism in their application
development work. This meant that developers were not able to leverage the
extensive collection of tools and applications available for the desktop
Windows/PC marketplace. With the Hyperkernel product, development in a
mainstream operating system architecture is now practical.


         PARAGON(TM)

         The Company's SCADA software is called Paragon (TM). Paragon was
developed by Intec, which the Company acquired through a merger in March 1997.
Paragon is a software package which regulates the control and management of
process information and delivers high performance and reliability in networked
applications with a scaleable database design. The open modular design and
dynamic connectivity of Paragon simplify the integration into enterprise-wide
networks. Paragon supports seamless cross-platform communication among operating
systems from Windows NT to Windows 95 and OS/2 on the same network.

         Paragon competes with other software product offerings from other
companies, most notably Wonderware and Intellution. However, the flexible
feature set of Paragon and its networking capabilities provide users with
advantages over competitive products. Paragon's built-in mechanisms allow data
exchange with third-party applications through DDE, standards or programming
languages. Paragon separates application functions into servers which acquire,
generate and store information. Peer-to-peer communication between any
client/server or server/server pair occurs without a central server.




                                      -6-
<PAGE>   7
         FLOPRO(R)

         The Company's soft logic software is called FloPro(R). FloPro is a
flowchart programming system which executes from personal. FloPro is based upon
the technology in Patent Number 4,852,047 "Continuous Flow Chart, Improved Data
Format and Debugging System for Programming and Operation of Machines." The
programming system is used to create, debug, document and execute control
applications in an open architecture environment. Its open system architecture
allows operators to interface it concurrently with many different input/output
systems, motion controllers, message units and RF tag/bar code systems. FloPro
simplifies machine control system development by allowing the use of multiple
flowcharts, each one handling a relatively simple task, thus allowing for the
concurrent development of applications by a team of control engineers. These
flowcharts communicate with each other in a multi-tasking environment, which
means that the control application is easy to create and understand.
Additionally, FloPro is self-documenting in that it is a programming language
based on the flowcharts; there is no need to translate the flowcharts to ladder
logic. The use of FloPro and a PC replaces the need for PLCs and ladder logic
for machine control applications. FloPro is in use at several General Motors
Corporation manufacturing facilities. FloPro systems at GM's PowerTrain Group
control several thousand machines used to manufacture engines and transmissions.

         FloPro competes with several products offered by companies of similar
or smaller size than Nematron in the soft logic marketplace. The soft logic
marketplace is an emerging market that is expected to grow significantly in the
next several years as PCs and soft logic software programs replace PLCs and
ladder logic software. Several of the Company's competitors license the
technology upon which FloPro is based. The advantages of the FloPro product as
compared to competing products is that the software is self-documenting, thus
reducing programmer time; it costs less than many other products; it operates on
open PC architecture; and it reduces plant down time through diagnostic messages
and fast execution time.

         POWERVIEW(R)

         PowerVIEW is a 32-bit Windows-based application development and
run-time system. The application development system serves as a single point of
control for building graphical display panels and configuring hardware, I/O
connections, process variables, alarms, messages and all other events associated
with the operation of a machine. A high-speed run-time compliments the project
manager portion of the system, but operates on a 32-bit real-time preemptive
multi-tasking microkernel more naturally suited to high-speed, real-time process
control. When the application project is downloaded to the run-time system and
the workstation is plugged into a PLC or I/O network, it runs automatically and
scans the I/O network at rates higher than other commercially available
workstations, updating the screens and sending instructions to the PLC virtually
instantaneously.

         PowerVIEW competes with other software product offerings from other
companies, most notably Allen Bradley and Eaton IDT. However, the product is
unique in that it runs on open architecture PC platforms and is a 32-bit
Windows-based application development system and its run time executes from
solid state memory.



         AUTONET(TM)

         The Company's test and measurement software is called AutoNet(TM), and
is sold to commercial and industrial companies primarily for use in a test cell
environment. AutoNet allows for data acquisition and real time processing of
high-speed data while performing multiple functions. AutoNet graphically
displays real time information through a wide variety of configurable graphic
instruments, trends and Cartesian plots. AutoNet performs real-time
mathematical, statistical and trigonometric calculations for control, test
sequencing, filtering and batch management of data. It features color coded
annunciation of alarm information, diagnostic files and automatic time stamps,
and presents stored data in report, historical graphics or ad hoc queries.

         AutoNet competes with products offered by other companies, most notably
Hewlett Packard and National Instruments. The AutoNet product is unique in that
it is a real time operating system which operates in a performance region that
competitive products do not.

SALES CHANNELS

         The Company employs three forms of sales channels. A network of
high-tech industrial distributors is the Company's primary sales channel.
Private-label accounts that remarket Nematron's products primarily through their
own networks of industrial electrical distributors are a less significant sales
channel for the Company's products. In addition, the Company sells its products
to major original equipment manufacturers ("OEMs") of industrial processing
systems and machines and to other major end users.

         Approximately 40% of the Company's total revenues are to distributors,
20% to private-label accounts and 40% to direct sales accounts. The Company
believes that it can increase its business as a result of increased marketing
and sales efforts for its OpenControl, Hyperkernel and Paragon software products
and its ICC hardware product lines. Additionally, with the significant
enhancements planned for its PowerVIEW and AutoNet software products, the
Company expects to introduce newer versions of these products for sale in 1999.
The Company presently markets OpenControl heavily to the automotive
manufacturing industry, and intends to expand that focus to other discrete and
process industries in fiscal 1999. The Company also intends to increase its
sales and marketing efforts for bundled hardware and software products.

         Three distributors accounted for 26% of the Company's total fiscal 1998
sales and two distributors accounted for 21% of the Company's total fiscal 1997
sales. These distributors resell products primarily to the automotive industry
and machine tool builders. No other private label, direct customer, or
distributor accounted for more than 5% of total Company sales in 1998 or 1997.
The ICC product family accounted for approximately 33% of total fiscal 1998
revenues. No other single model or product family accounted for more than 15% of
the Company's sales during 1998.

         The Company's distributors are typically companies with non-exclusive
written agreements that purchase inventory and resell it to their customers. In
addition, distributors typically provide customer training, application
engineering, and support. The Company has approximately 85 domestic distributor
branches and approximately 25 distributor branches in over 20 countries
internationally. The Company has regional sales managers covering major
geographic regions of the United States and Europe and several sales managers
who concentrate on key accounts nationwide. These managers are located in the
United States in Illinois, Massachusetts, Michigan, Ohio, Texas, Tennessee and
Virginia, and in major business centers in the Netherlands and the United
Kingdom. In addition, direct sales accounts and private label accounts are
handled by both key account sales managers as well as corporate executive
management.


MANUFACTURING AND SUPPLY

         The Company performs final assembly and testing for almost all hardware
products. The assembly process encompasses the assembly of sheet metal parts,
keyboards, displays, and electronic circuit boards into finished goods. In
addition, the Company performs some cable manufacturing, a limited amount of
circuit board assembly and wave soldering, and the repair and engineering
prototype assembly of surface mount technology components used on various logic
boards. The Company subcontracts the insertion and soldering of components on
circuit boards, and the fabrication of sheet metal, keyboards and front panel
bezels. The Company uses a number of independent firms for these subcontracted
services and is not materially dependent upon any third party that performs
these services. Selected models are built entirely to the Company's design by
vendors and purchased as complete products.

         A network of personal computer-based engineering workstations supports
accounting, purchasing, production, scheduling and inventory, as well as the
computer-aided design and development of electronic circuitry, circuit board
layout, programming of programmable logic devices, mechanical design and
software development.

         In addition, the Company has purchased and designed a variety of
assembly and test equipment to reduce the cost and ensure the quality of the
design and manufacturing process. The Company has made a substantial investment
in environmental chambers and electronic instrumentation used to certify that
the Company's products meet the severe industrial environments for which they
are intended.

         Some components used in the Company's products are currently purchased
from single or limited sources of supply. The Company believes that the loss of
one or more suppliers would not have a material long-term impact on its
operations but could cause some production delays. The Company experienced such
production delays in 


                                      -8-
<PAGE>   9

1998 when the Company became delinquent on certain suppliers' trade notes
payable, and as a result, the supplier refused to ship component parts to the
Company, even on a COD basis.


PRODUCT DEVELOPMENT

         The Company maintains an active product development program and
continues to supplement existing research and development capabilities through
active recruiting of technical personnel and development of proprietary
technology.

         The Company currently has a product development staff of approximately
20 professionals, including electrical and electronic design engineers,
mechanical design engineers, software design engineers, product managers,
application engineers and directly associated staff members involved in
technical documentation and product support. The Company also employs the
services of unrelated contract engineering companies on an as-needed basis. The
Company employs a separate group which is responsible for assuring the long term
quality and reliability of the Company's products. Within this quality assurance
group are quality, test, manufacturing and reliability engineers. Software
development activities are concentrated in the Foxboro, Massachusetts. Prior to
September 30, 1998, development was also performed in offices in Virginia Beach,
Virginia, Santa Clara, California and Hilliard, Ohio. Hardware development and
quality activities testing and control are concentrated in Ann Arbor, Michigan.

         The Company emphasizes product development and quality and the
employment of highly skilled and motivated individuals in the product
development and quality assurance areas. Management believes that its product
development staff is an important factor in the Company's ability to compete in
the markets in which its products are sold. During the fiscal years 1998 and
1997, the Company expended approximately $4,200,000 and $4,600,000,
respectively, for direct hardware and software product development and product
design quality, including those costs capitalized under Statement of Financial
Accounting Standards No. 86. All of such costs were sponsored by the Company.
These amounts represented 25% and 22% of total revenues in fiscal 1998 and 1997,
respectively.


INTELLECTUAL PROPERTY

         The Company's FloPro software product, which is sold as a separate
product but is also the underlying technology incorporated into the Company's
OpenControl product, is based upon the technology specified in a patent for
continuous flow chart, improved data formatting and a debugging system for
programming and operations of machines. This patent was issued in 1989 as a 17
year patent. The Company also was issued a patent in 1997 for a chassis locking
mechanism used on its Industrial Control Computer and certain other products.
The Company has no patents on other hardware products or computer designs. The
Company filed a patent application for its Hyperkernel real-time extension to
Windows NT during fiscal 1996. The Company has an active technology committee to
review trademark and patent potential on an ongoing basis.

         In addition to trademarks on the trade names under which the Company
does or did business, including Nematron(R), NemaSoft(R), Imagination Systems
and Universal Automation, the Company also owns trademarks on certain of its
products, including Industrial Workstation(TM), ToolBox(R), ToolBox Plus(TM),
OpenControl(TM), Hyperkernel(R), Paragon(TM), FloPro(R), AutoNet(TM) and
PowerVIEW(R).

         The Company's software products are sold under licenses to use the
products as specified in the underlying contract. Certain of the licenses for
the use of the FloPro software product are site licenses for unlimited use of
the master copy of the product in a specified building, plant or group of
plants. To date, the revenue from these site licenses has not been a significant
source of revenue to the Company. Also, the Company has licensed its soft logic
technology to several unrelated companies under royalty arrangement; these
arrangements are not currently a significant source of revenue.

EMPLOYEES

         The Company currently employs approximately 90 full time employees,
including over 60 in Ann Arbor, Michigan, 12 in Foxboro, Massachusetts, 6 in the
United Kingdom, and 10 at other locations. None of the Company's employees are
represented by a collective bargaining unit, and the Company believes its
employee relations to be good.


ENVIRONMENTAL COMPLIANCE

         The Company's products must comply with federal, state and/or local
laws and regulations that have been enacted or adopted relating to the discharge
of materials into the environment, or otherwise relating to the protection of
the environment. The Company believes that continuing efforts and expenditures
incurred to maintain compliance with such laws and regulations will not have a
material effect on capital expenditures, earnings or the competitive position of
the Company.


ITEM 2.  PROPERTIES.

         The Company's headquarters and principal manufacturing facilities are
located in Ann Arbor, Michigan in a two-story building containing a total of
approximately 51,200 square feet of space. Of this space, approximately 6,400
square feet remain unfinished and available for future office or assembly
expansion. This facility, located on approximately five acres of land, has been
designed such that further expansion of up to 20,000 square feet may be
accommodated. The Ann Arbor facility was designed and built to the Company's
specifications and is Company owned, subject to mortgages by its bank lenders.
The mortgage loan payable to Chelsea State Bank is in the principal amount of
approximately $1,999,000 at September 30, 1998, bears interest at 9.5% per annum
and is payable in monthly installments of $29,900 through September 2001, at
which time the remaining balance of $1,491,000 is due.

         The Company's Foxboro, Massachusetts's facility consists of
approximately 3,200 square feet of leased space in a three-story office
building. Leasehold improvements consist of certain changes for specific office,
service, and storage requirements according to the Company's needs. The
operating lease for this facility is non-cancelable through August, 1999.

         The Company's European facilities are located in Chichester, United
Kingdom, and consist of approximately 5,000 square feet of leased space in a
20,000 square foot office complex. Leasehold improvements consist of certain
changes for specific office, service, and warehouse requirements according to
the Company's needs. The operating lease for this facility is non-cancelable
through December 1998, at which time the Company will move into a 2,000 square
foot leased facility in a multi-tenant building in Portsmouth, United Kingdom
under a non-cancelable operating lease through December 2001.

         The Company believes that all of its facilities are adequate for its
present and anticipated operations.


ITEM 3.  LEGAL PROCEEDINGS.

         Except as described below, the Company is not involved in any legal
proceedings other than routine, non-material litigation incidental to the
business.

         Following the Company's announcement of potential material adjustments
to its financial statements for the years ended September 30, 1996 and 1997
relating to the accounting treatment of one of the Company's contracts, a
complaint captioned Levine v. Nematron Corporation et. al., Case No. 98 CIV
3309, was filed on or about May 8, 1998 in the District Court for the Southern
District of New York. This lawsuit names as defendants the Company, certain of
its officers and directors, its former independent auditor and the underwriter
for the Company's June 5, 1996 public offering of Common Stock. Plaintiff seeks
to represent a class of shareholders who purchased the Company's Common Stock
from January 31, 1996 through April 28, 1998. Plaintiff filed an amended
complaint in October 1998. The amended complaint claims violations of securities
laws and common law based on allegations that defendants made untrue statements
of material facts and that they omitted material facts necessary in order to
make the statements not misleading. The complaint seeks unspecified damages and
costs. In December 1998, the case was transferred to the United States District
Court for the Eastern District of Michigan. Management believes that the outcome
of this case will not have a material adverse effect on the Company.

                                      -10-
<PAGE>   11



         On October 14, 1998, a former employee filed a complaint in the
District Court in Virginia against the Company alleging that she was terminated
illegally and in retaliation for her complaints regarding sexual harassment in
the workplace. Plaintiff seeks damages of $500,000. The same plaintiff had filed
an EEOC complaint in May 1998 alleging improper dismissal relating to sexual
harassment, and the EEOC complaint was denied in June 1998. Management believes
that the outcome of this case will not have a material adverse effect on the
Company.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS

         The following discussion and analysis contains a number of "forward
looking statements" within the meaning of the Securities and Exchange Act of
1934, as amended, with respect to expectations for future periods which are
subject to various uncertainties explained herein and in "Management's
Discussion and Analysis of Operations - Uncertainties Relating to Forward
Looking Statements."

Overview

         Management's operating strategy is to incorporate software products
developed internally and those software products obtained through its
acquisitions of other entities into the Company's product offerings and to
vertically integrate its product offerings to include both hardware and software
products related to industrial automation. The Company's marketing and sales
efforts to existing and new customers include stand-alone computers, software
products and bundled products. The Company intends to continue its shift of
business away from dominance by computer hardware sales, and will pursue the
development of new software products and the enhancement of existing software
products. Additionally, the Company has identified new markets for both hardware
and software products, and will pursue new business from customers which offer
the greatest likelihood of large unit volume. Management anticipates significant
growth in the industrial software marketplace and intends, through concentrated
development and aggressive marketing and sales efforts, to capture an increasing
percentage of that market.

Fiscal 1998 Compared to Fiscal 1997

         Net revenues were $16,829,000 in fiscal 1998 compared to $20,875,000 in
fiscal 1997. This represents a decrease of $4,046,000, or 19.4%, compared to
fiscal 1997. Software revenues increased to 23.9% of total sales in 


                                      -12-

<PAGE>   13

fiscal 1998 versus 16.3% in fiscal 1997, reflecting a full year of Paragon sales
in 1998 compared to six months of sales of the Paragon software product after
Intec was acquired in March 1997. The decrease in sales of Industrial
Workstations and related parts and service as a percentage of total fiscal 1998
revenues resulted primarily from the expiration at the end of fiscal 1997 of
significant contracts with a major customer. Additionally, when the Company
experienced financial difficulty in the third and fourth quarters of fiscal
1998, the customer order rate decreased due to shipment uncertainty. Also, the
Company was unable to secure component parts for subsequent assembly into
finished product due to the lack of cash and available financing.

         Foreign revenues decreased in fiscal 1998 by $759,000, or 12.7%, from
foreign revenues in fiscal 1997, due to a combination of higher software sales
but lower hardware sales due to the change in focus of the sales staff in
Europe. Domestic revenues decreased in fiscal 1998 by $3,287,000, or 22.1%,
compared to domestic revenues in fiscal 1997. This decrease is due primarily to
fewer sales personnel, the expiration of major a major contract in 1997 that was
not replaced in 1998, reluctance of customers to place orders in the third and
fourth quarters of fiscal 1998 and the lack of available cash or credit with
which to purchase component parts during that time.

         Management expects that the working capital provided by the proceeds
from the issuance of $1 million of convertible promissory notes in December
1998, the additional private placement currently underway, borrowings under the
bank credit facility and borrowings under an additional credit facility from a
finance company entered into in December 1998 will permit the Company to
purchase the component parts needed to return the Company to more customary
production levels for the remainder of fiscal 1999. Also, assuming the Company
is able to fill the existing backlog and that the current order rate continues,
management expects that sales will increase in fiscal 1999 over 1998.
Additionally, management expects that sales will increase due to the recent
positive market response to the Company's Paragon and OpenControl software
products and to its ICC hardware products. If resources are available, the
Company intends to increase its marketing and sales efforts by hiring and
training new sales personnel in certain major metropolitan and industrial areas,
expanding its selling efforts in Europe and strengthening its sales management.
The Company's expectation of revenue growth in fiscal 1999 is also based on the
belief that the products introduced in the last several years and products
planned for release in fiscal 1999 are and will continue to be technologically
more advanced than certain comparably priced competing products, and also on the
expectation that the expansion of the Company's product line will result in the
addition of new distributors and partnership arrangements.

         The Company's actual results of operations for fiscal 1999, however,
cannot be predicted with certainty and are subject to a number of risks. For
example, the Company may not close on its second traunch of a private placement,
or the amount of capital raised may not be sufficient to provide the Company
adequate working capital to sustain operations. Additionally, contracts may be
canceled or current purchase orders rescinded, the marketplace may not respond
favorably to the Company's marketing and sales efforts, the Company may be
unable to attract and retain qualified sales staff and management, latent
technological deficiencies in the new products may reduce demand for the
products, the anticipated interest of new distributors in the Company's products
may not materialize, and technological advances by competing companies and
competing products may reduce demand for the Company's products. The occurrence
of any of these events could result in the Company's net revenues growing at a
reduced rate or declining.

         Cost of revenues include costs related to raw materials and component
parts, direct labor, overhead, amortization of capitalized software costs,
provisions for warranty costs on products sold and provisions for excess and
obsolete inventory. There were no material changes in costs of raw materials,
direct labor or overhead as a percentage of total revenue. However, during
fiscal 1998, the Company provided significant reserves for obsolete materials
related to certain discontinued Industrial Workstation models. As a consequence
of restricted cash resources and the price competition causing decreasing
margins on certain older products, together with the success of ICC product
models marketed to the automotive and machine tool industries, the Company
determined in the fourth quarter of fiscal 1998 to discontinue certain families
of products. Additionally, during the fourth quarter of fiscal 1998 the Company
determined to concentrate future sales efforts on current models and future
models of ICC products. Provisions for excess and obsolete inventory totaled
approximately $1.3 million, including approximately $1,000,000 recorded in the
fourth quarter of fiscal 1998. Absent the special provision for inventory
obsolescence in fiscal 1998 and the special charges to cost of revenues recorded
in fiscal 1997, the cost of sales as a percentage of total revenues was 62.5% in
fiscal 1998, compared to 61.8% in fiscal 1997.

         Product development expenses increased in fiscal 1998 by 2.1%, over the
fiscal 1997 level, primarily due to the development efforts on software
products. Product development expenses, which are a function of new 



                                      -13-
<PAGE>   14

product research and development and existing product enhancement efforts, are
expected to remain relatively constant in fiscal 1999 compared to fiscal 1998.
The actual level of product development expense for fiscal 1999 is subject to
various uncertainties, including the ability of the Company to attract and/or
retain qualified persons to perform the planned activities. In addition, it is
possible that research and development efforts could proceed differently than
anticipated or the Company may be required to expense, rather than to
capitalize, the costs related to such efforts.

         Selling, general and administrative expenses in fiscal 1998 increased
by $1,164,000, or 12.4%, over the fiscal 1997 level, due principally to the
effect of including the costs and expenses of the former Intec personnel and
other costs for a full year in fiscal 1998. Additionally, significant sales and
support efforts were expended to secure and support a large General Motors
contract under which ICC products will be supplied beginning in fiscal 1999. The
rate of increase in selling, general and administrative expenses in fiscal 1999
is expected to be less than in fiscal 1998 due to scheduled increases in
marketing activities and planned increases in sales staff levels and in sales
activities, offset by reductions in fixed costs, administrative personnel and
other discretionary costs which have been completed in the first quarter of
fiscal 1999. The actual rate of growth is subject to various uncertainties,
however. These include difficulties in attracting and retaining qualified
personnel as planned, the ability of management to effect operational
improvement and the potential need to curtail planned marketing and sales
efforts and other activities if cash resources are not available.

         Other operating expenses in fiscal 1998 included a write down of
purchased intangible assets, including goodwill, totaling $1,320,000 and a
provision of $350,000 for payroll and other costs related to the shutting down
of three satellite offices in October and November 1998. Certain intangible
assets were acquired by the Company in the Intec merger in March 1997; in the
fourth quarter, due to personnel changes and changes in software development and
operating and marketing strategies, certain intangible assets, including
associated goodwill, were written down to net realizable value.

         Sundry expense in fiscal 1998 was $17,000 compared to sundry income of
$104,000 in fiscal 1997. The decrease in sundry income (expense) is due to the
results from investing available funds in early fiscal 1997. In fiscal 1998, the
Company also recognized a loss of $55,000 on the disposal of property and
equipment.

         Interest expense in fiscal 1998 increased by $373,000 due to high
average borrowing levels in fiscal 1998 than in fiscal 1997. The borrowing
levels were higher due to the capital leases entered into in fiscal 1998, as
well as the use of the bank line of credit to fund cash operating losses during
fiscal 1998.


Year 2000 Issue

         The Year 2000 Issue ("Y2K") is the result of certain computer programs
being written using two digits rather than four digits to define the applicable
year. Computer systems with a Y2K problem will be unable to interpret dates
beyond the years 1999, which could cause a system failure or other computer
errors, leading to disruptions in operations. In 1997, the Company began to
assess its Y2K readiness and adopted a three-phase program for Y2K information
systems compliance. Phase I is the identification of systems and products with
which the Company has exposures to Y2K issues. Phase II encompasses the
development and implementation of action plans to be Y2K compliant in all areas
by mid-1999. Phase III includes final testing of each major area of exposure to
ensure compliance. The Company has identified four major areas determined to be
critical for successful Y2K compliance: (1) financial and information system
applications; (2) software products currently sold; (3) third-party
relationships and 4) non-information technology areas such as security,
telephone systems and climate control systems.

         The Company is finishing Phase I of its program. The Company has
contacted all significant software suppliers and, due to recent implementation
of its major financial and operational software, believes that its financial and
operational software is Y2K compliant. The Company has also reviewed for Y2K
compliance its hardware and software products, including the firmware imbedded
in certain hardware products, marketed and sold to third parties. The Company
has used its employee engineers and others in its review and testing procedures.

         The Company has identified one older software product, used for
monitoring and testing in a test cell environment (not related to machine
control) which needs to be modified to correct a Y2K problem. The Company
estimates that the cost to modify the product is approximately $50,000, all of
which relates to the salary and benefits 


                                      -14-
<PAGE>   15

of software development employees of the Company, none of which has been
expended to date. The Company intends to fix this Y2K issue and notify its
customers when a solution is available. The Company intends to supply its
customers with the Y2K compliant software without charge. The Company intends to
fund the costs of this effort out of operating funds in fiscal 1999. If the
product cannot be remedied in a cost efficient manner, the Company may determine
to cease marketing and production of the product; such action, however, is not
expected to have a material adverse effect on the Company's results of
operations.

         The Company has relationships with, and is to varying degrees dependent
upon, various third parties that provide funds, information, goods and services
to the Company. These include the Company's bank lender, utility providers,
stock transfer agent, and suppliers of components. The Company is attempting,
through informal contacts, to assess the compliance of these third parties.
While not all parties have informed the Company as to their status, the most
significant of these third parties have represented that their systems and
products are Y2K compliant. The Company will continue with this assessment in
fiscal 1999. The Y2K compliance of the systems of these third parties is outside
the Company's control and there can be no assurance that any of these third
parties will not experience a systems failure due to Y2K.

         Because the Company expects that the systems within its control will be
Y2K compliant before the end of 1999, the Company believes that the most
reasonably likely worst case scenario is a compliance failure by one or more of
the third parties described above. Such a failure would likely have an effect on
the Company's business, financial condition and results of operations. The
magnitude of that effect, however, cannot be quantified at this time because of
variables such as the type and importance of the third party, the possible
effect on the Company's operations and the Company's ability to respond. Thus,
there can be no assurance that there will not be a material adverse effect on
the Company if such third parties do not remediate their systems in a timely
manner and in a way that is compatible with the Company's systems.

         As a result, the Company will develop contingency plans that assume
some estimated level of noncompliance by, or business disruption to, these third
parties. The Company intends to have contingency plans developed by the end of
its third quarter of fiscal 1999 for third parties determined to be at high risk
of noncompliance or business disruption or whose noncompliance or disruption,
while not high risk, is considered likely to materially affect the Company. The
contingency plans will be developed on a case-by-case basis, and may include
plans for switching to Y2K compliant suppliers, Judgments regarding contingency
plans are subject to many uncertainties and there can be no assurance that the
Company will correctly anticipate the level, impact or duration of noncompliance
or that its contingency plans will be sufficient to mitigate the impact of any
noncompliance. Some material adverse effect to the Company may result despite
such contingency plans.

         To date, the Company has not expended any incremental costs to
remediate Y2K problems, in that all efforts have been expended by existing
engineering and application support and other personnel These costs have been
expensed as incurred in fiscal 1998. The Company estimates total Y2K remediation
costs at $75,000 incrementally over the next four quarters. Estimates of time,
cost and risks are based on currently available information. Developments that
could affect estimates include, without limitation, the availability of trained
personnel, the ability to locate and correct all noncompliant systems,
cooperation and remediation success of third parties material to the Company,
and the ability to correctly anticipate risks and implement suitable contingency
plans in the event of system failures at the Company or third parties.

<PAGE>   16

December 15, 1997, and is not expected to impact the Company's financial
position or results of operations. The Company will comply with the requirements
of SOP 97-2 in fiscal year 1999.

Liquidity and Capital Resources

         In August, 1998, the Company recruited Mr. Mathew S. Galvez to assist
the Company in its efforts to stem the significant ongoing losses being suffered
by the Company. At the direction of the Board of Directors, Mr. Galvez
entertained discussions to sell the Company as well as to take on additional
investors and financing.

         By the end of October, 1998, the Company was overadvanced on its
revolving credit facility, and was facing imminent foreclosure by the Company's
lenders. In early November 1998, after unsuccessful attempts to sell the
business or solicit working capital through other means, and when the Company
was faced with imminent closing of its business, the Company negotiated an
arrangement with a group of creditors that provided essential working capital to
prevent a complete closedown of the Company. The proposal was submitted to the
bank, and percipiteated a forbearance agreement from the Company's bank.
Following receipt of support from the bank, the management and Board of
Directors agreed to support the arrangement as an offer of last resort. It was
the opinion of management and the Board of Directors that keeping the Company as
an ongoing entity, even if the existing shareholder's interests were materially
diluted, was a much better result than shutting down the business and risking
losing existing business with its significant customers, new business, the loss
of its management and employees, and other detrimental effects associated with a
shut-down.

         The arrangement with the new investors called for the issuance of
convertible notes expiring March 31, 1999, in the aggregate of $1 million, with
the notes being convertible into options to acquire the Company's common stock
at $.25 per share. In addition, the investors were given the option to
contribute an additional $3 million in cash in exchange for convertible notes
also excersizable for options to purchase shares at $.25 per share. The
noteholders option to contribute the $3 million in exchange for convertible
notes expires January 31, 1999.

         The Company is party to a bank line of credit which permits borrowing
up to $5,000,000, subject to an availability formula based upon a percentage of
eligible accounts receivable and inventory. At September 30, 1998, approximately
$3.5 million was outstanding on the line, including a $900,000 overadvance which
the bank agreed to permit until October 31, 1998 in connection with the
extension of the expiration date of the line of credit to the same date. The
expiration date was subsequently extended to January 31, 1999. As of December
21, 1998, the amount outstanding was reduced to $2.2 million, and the amount
available under the formula was $.9 million. Amounts borrowed under the facility
bear interest at prime plus 2.0% (10.25% effective rate at December 21, 1998).
Prior to the expiration of the line of credit on January 31, 1999, the Company
plans to negotiate an extension of the expiration date of the line of credit.
Although management believes that by January 31, 1999 the receivable and
inventory levels, upon which the borrowing base is calculated, will increase,
and the amount of over-advance from the bank will decrease, there can be no
assurance that the credit line will be extended. Consequently, if negotiations
to extend the credit line fail, management will seek financing from other
financing sources, which may not materialize, or if such sources are available,
the cost of such arrangement may be significantly higher than the current bank
agreement.

         As discussed above, on December 1, 1998, the Company closed on a
private placement of $1 million of convertible promissory notes. The notes bear
interest at 7% and are due on March 31, 1999. The notes are payable with and
convertible into the Company's common stock (subject to shareholder approval)
valued at $.25 per share and grant the note holders options to acquire
additional convertible promissory notes in the amount of $3 million through
January 31, 1999. Shareholder approval is also required for the conversion of
the option shares. Management believes that the options will be exercised and an
additional $3 million in funding will be received prior to the option expiration
date. The board intends to call a meeting of the shareholders prior to the
expiration of the option on March 31, 1999 and seek to obtain shareholder
approval for the issuance of the shares pursuant to the convertible promissory
notes and the option agreement. See Note 2 to the Consolidated Financial
Statements.

         The Company also successfully negotiated the conversion of $1.7 million
of trade accounts payable into short-term trade notes payable. Although the
Company was delinquent on the terms of these notes at September 30, 1998, the
Company has paid or received extensions of all past due payments as of December
18, 1998.

         In order for the Company to have sufficient short-term liquidity to
continue operations for the remainder of fiscal 1999, the line of credit must be
renewed or replaced, the Company must receive the proceeds from the 





                                      -16-

<PAGE>   17

additional convertible promissory notes described above and the Company must be
able to pay the principal and interest under all of its convertible notes with
Common Stock on March 31, 1999. If the Company is not successful in
accomplishing these goals, the Company would be forced to curtail its operations
and either sell the Company to a third party or seek protection under federal
bankruptcy laws.


Uncertainties Relating to Forward Looking Statements

         "Item 6. Management's Discussion and Analysis of Operations" and other
parts of this Form 10-KSB contain certain "forward-looking statements" within
the meaning of the Securities Act of 1934, as amended, based on current
management expectations. Actual results could differ materially from the
forward-looking statements due to a number of uncertainties, including, but not
limited to, those discussed in this section and in "Business - Products, Market
and Competition" above.

         Factors that could cause future results to differ from these
expectations include the failure of the bank renew its line of credit agreement
when borrowings thereunder become due, the inability of the Company to pay the
principal and interest of the convertible promissory notes with Common Stock at
the March 31, 1999 maturity date, the failure of the Company to receive the
proceeds of the additional $3 million of convertible promissory notes described
above, the decline of economic conditions in general and conditions in the
automotive manufacturing industry in particular, a reduction in demand for the
Company's products and services, the inability of the Company to successfully
implement its strategy to lead the industrial automation market migration from
closed architecture PLCs to open architecture PC-based solutions, changes in
Company strategy, reductions in product life cycles, competitive factors
(including the introduction or enhancement of competitive products), pricing
pressures which result in materially reduced selling prices for the Company's
products, raw material price increases, delays in introduction of planned
hardware and software products, software defects and latent technological
deficiencies in new products, changes in operating expenses, fluctuations in
foreign exchange rates, the inability to attract or retain sales and/or
engineering talent, changes in customer requirements, unexpected Y2K issues in
the Company's products or systems and evolving industry standards.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



THE BOARD OF DIRECTORS
Nematron Corporation:

We have audited the accompanying consolidated balance sheet of Nematron
Corporation and subsidiaries as of September 30, 1998, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
the years ended September 30, 1997 and 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Nematron Corporation
and subsidiaries as of September 30, 1998, and the results of their operations
and their cash flows for the years ended September 30, 1997 and 1998, in
conformity with generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in note 2 to the
consolidated financial statements, the Company has suffered recurring losses
from operations, has experienced cash flow difficulties and is in default of its
loan agreements with its primary lenders. These matters raise substantial doubt
about the Company's ability to continue as a going concern. Management's plans
with respect to these matters are also discussed in note 2. The consolidated
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                      NEMATRON CORPORATION AND SUBSIDIARIES
                   Notes to Consolidated Financial Statements
                           September 30, 1997 and 1998



(1)    BUSINESS

       Nematron Corporation (the "Company") designs, manufactures, and markets
       environmentally ruggedized computers and computer displays known as
       industrial workstations, and designs, develops, and markets software for
       worldwide use in factory automation and control and in test and
       measurement environments.

(2)    GOING CONCERN MATTERS

       The accompanying financial statements have been prepared on a going
       concern basis, which contemplates the realization of assets and the
       satisfaction of liabilities in the normal course of business. As shown in
       the financial statements, during the years ended September 30, 1997 and
       1998, the Company incurred losses of $11,498,379 and $9,009,828,
       respectively. These losses have contributed to the Company's difficulties
       in generating sufficient cash flow to finance operations. These factors,
       among others, raise substantial doubt about the Company's ability to
       continue as a going concern. The accompanying financial statements do not
       include any adjustments that might result from the outcome of this
       uncertainty.

       Management's plans with respect to these matters include the following:

       On December 1, 1998, the Company's primary lender extended the maturity
       date of the line of credit and the term loan to January 31, 1999. The
       lender also granted an adjustment to the borrowing base to allow a
       permitted over-advance of $1 million. The line of credit note was
       partially repaid with a portion of the proceeds from a private placement
       completed on December 1, 1998. As a result of the paydown and the
       operating activity subsequent to year end, the Company has returned to
       compliance with the limits of its adjusted borrowing formula.

       On December 1, 1998, the Company completed a $1 million private placement
       of convertible promissory notes to a group of private investors. The
       notes are convertible into common stock of the Company at $0.25 per
       share, bear interest at 7% per annum and become due on March 31, 1999.
       The notes grant the note holders an option through January 31, 1999 to
       purchase additional convertible notes totaling $3 million, which are
       convertible into common stock at $0.25 per share. Management believes
       that the options will be exercised and an additional $3 million in
       funding will be received prior to the option expiration date. Issuance of
       shares in excess of 20% of the number of shares currently outstanding
       will require shareholder approval, which the Board of Directors will seek
       at the 1999 annual meeting of shareholders in March 1999.

       A portion of the proceeds from the private placement was used to pay
       delinquent vendor notes. When these notes became delinquent in the first
       quarter of fiscal 1999, certain vendors ceased product delivery to the
       Company. Upon the payment of the past due notes, the Company's vendors
       agreed to resume the shipment, on a COD basis, of component parts for
       subsequent assembly and sale to customers. Component parts have been
       purchased in sufficient quantities so that management believes the
       Company will be able to ship the current customer order backlog in a
       timely manner and keep current with the anticipated order rate. Based
       upon the actual and anticipated component purchases and subsequent
       forecasted sales of finished product, management expects that current
       operations and available credit facilities will be sufficient to pay its
       costs and expenses as they become due.

(2)    GOING CONCERN MATTERS, CONTINUED

       Management plans to close on the private placement of the additional $3
       million convertible notes by the expiration of the bank agreement, and to
       use a portion of the additional proceeds to further pay down the credit
       line. After this anticipated paydown, management expects borrowings to be
       below the basic borrowing base (exclusive of the permitted overadvance).
       Further, management intends to negotiate with its bank lender a longer
       term extension of the expiration date of the financing agreement.
       Management believes that an extension of the credit line is possible,
       assuming that accounts receivable and inventory levels increases to
       reduce or eliminate the amount of the overadvance as a result of the
       anticipated sales increases, and assuming that the Company is able to
       complete the additional placement of $3 million of its convertible
       promissory notes prior to January 31, 1999.

       Management believes successful implementation of the plans set forth
       above will enable the Company to continue as a going concern. If the
       Company is not successful in executing these plans, the Company maybe
       forced to curtail its operations and either sell the Company or seek
       protection under federal bankruptcy laws.

 (3)   SUMMARY OF ACCOUNTING PRINCIPLES

       Principles of Consolidation

       The accompanying consolidated financial statements include the accounts
       of the Company and its wholly owned subsidiaries - Nematron Europa BV
       ("NEBV"), an inactive Netherlands corporation; Nematron Ltd., a United
       Kingdom corporation acquired in the Intec acquisition; NemaSoft, Inc.
       ("NemaSoft"); and Imagination Systems, Inc. ("ISI"), Michigan
       corporations formed in 1995 and 1996, respectively. All significant
       intercompany transactions and balances have been eliminated in
       consolidation.

       During the fiscal year ended September 30, 1997, the Company acquired two
       software design and manufacturing companies. Intec Controls Corp.
       ("Intec"), a Massachusetts corporation, was acquired on March 31, 1997,
       and Virtual-Time Software, Inc. ("VTS"), a California corporation, was
       acquired on June 20, 1997. The consolidated operations of the Company for
       1997 include the results of Intec and VTS since the dates of their
       respective acquisitions (see note 4).

(3)    SUMMARY OF ACCOUNTING PRINCIPLES, CONTINUED

       Cash Equivalents

       The Company considers all highly liquid debt instruments with original
       maturities of three months or less at the date of purchase to be cash
       equivalents.

       Inventories

       Inventories are carried at the lower of cost or market. Cost is
       determined by the first in, first out method. Provision is made to reduce
       inventories (including demonstration units) to net realizable value for
       excess and/or obsolete inventories based upon an item-by-item review of
       quantities on hand compared to estimated future usage for sales and
       service.

       Property and Equipment

       Property and equipment are stated at cost. Capital leases are recorded at
       the present value of future minimum lease payments and are amortized over
       their primary term. Depreciation is provided over the estimated useful
       lives of the assets, ranging from 3 years for certain factory and office
       equipment to 33 years for the Company's manufacturing facility.
       Depreciation is computed using the straight-line method for financial
       reporting purposes and accelerated methods as promulgated by the IRS for
       tax reporting purposes.

       Software and Related Development Costs

       Certain computer software development costs and purchased software
       technology have been capitalized. Capitalization of computer software
       development costs begins upon establishment of technological feasibility.
       The establishment of technological feasibility and the ongoing assessment
       of recoverability of capitalized computer software development costs
       requires considerable judgment by management with respect to certain
       external factors, including, but not limited to, anticipated future gross
       revenues, estimated economic life, and changes in software and hardware
       technology. The Company continually reviews the recoverability of
       capitalized software costs based on estimated cash flows. Software costs
       are written off, as amortization expense, at the time a determination has
       been made that the amounts are not recoverable.

 (3)   SUMMARY OF ACCOUNTING PRINCIPLES, CONTINUED

       Software and Related Development Costs, Continued

       During the year ended September 30, 1997, capitalized software and
       related development costs, net of amortization, decreased by
       approximately $1,701,000. The decrease was due to the capitalization of
       approximately $2,435,000 of salaries and other costs incurred during the
       year, the acquisition of approximately $478,000 of costs pursuant to the
       Intec and VTS acquisitions, offset by approximately $553,000 of
       amortization of capital costs, and the write-off of approximately
       $4,061,000 related to abandoned software projects (see notes 4 and 5).
       During the year ended September 30, 1998, capitalized software and
       related development costs, net of amortization, increased by
       approximately $1,218,000, primarily relating to the capitalization of
       approximately $1,988,000 of salaries and other costs incurred during the
       year, offset by approximately $770,000 of amortization of capitalized
       costs.

       Amortization of capitalized computer software development costs is
       provided on a product-by-product basis using the greater of the amount
       computed using (a) the ratio that current gross revenues for each product
       bear to the total of current and anticipated future gross revenues for
       that product, or (b) the straight-line method over the remaining
       estimated economic lives of the respective products, ranging from two to
       five years.

       Intangible Assets

       Other intangible assets are carried at cost less accumulated
       amortization, which is calculated on a straight-line basis over the
       estimated useful lives of the assets, ranging from five to ten years. For
       the year ended September 30, 1997, amortization was approximately
       $636,900. For the year ended September 30, 1998, amortization was
       approximately $2,035,900, including a provision for impairment of
       approximately $1,319,700 relating to the write down of certain purchased
       intangible assets (See Note 5).

       The carrying value of intangible assets is periodically reviewed, and
       impairments are recognized when the expected future cash flows derived
       from such intangible assets are less than their carrying value.

       Stock Option Plan

       On October 1, 1996, the Company adopted Statement of Financial Accounting
       Standards No. 123, Accounting for Stock-Based Compensation ("SFAS 123"),
       which permits entities to recognize as compensation expense over the
       vesting period the fair value of all stock-based awards on the date of
       grant. Alternatively, SFAS No. 123 also allows entities to continue to
       apply the provisions of APB Opinion No. 25 and provide pro forma net
       income and pro forma earnings per share disclosures for employee stock
       option grants as if the fair-value-based method defined in SFAS No. 123
       had been applied. The Company has elected to continue to apply the
       provisions of APB Opinion No. 25 and provide the pro forma disclosure
       provisions of SFAS No. 123 (See Note 12).

(3)    SUMMARY OF ACCOUNTING PRINCIPLES, CONTINUED

       Foreign Currency Translation

       The assets and liabilities of the Company's foreign subsidiaries, NEBV
       and Nematron Ltd., denominated in foreign currency, are translated at
       exchange rates in effect on the balance sheet date, and revenue and
       expenses are translated using a weighted average exchange rate during the
       year. Gains or losses resulting from translating foreign currency
       financial statements are recorded in a separate component of
       stockholders' equity. Gains or losses resulting from foreign currency
       transactions are included in the net loss.

       Revenue Recognition

       Revenues from product sales are recognized upon shipment. Revenues from
       service and repair of computers are recognized as the services are
       performed. Revenues from software and engineering development are
       recognized as the Company performs the services, in accordance with the
       contract terms. Revenues from extended warranty agreements covering
       software are recognized ratably over the terms of the agreement with the
       customer. Revenues from license agreements are recognized upon delivery
       of the software and performance of all obligations under the applicable
       agreement. The Company has established programs which, under specified
       terms and limited conditions, enable its distributors to return limited
       amounts of product. The effect of these programs is estimated, and
       current-period revenues and cost of revenues are reduced accordingly.

       Research and Development Costs

       Research and development costs are expensed when incurred. These costs,
       representing engineering salaries, fringe benefits, and a portion of the
       Company's overhead, are included in the accompanying consolidated
       statements of operations as a component of product development costs.
       Research and development costs were approximately $1,615,000 and
       $1,287,000 for the years ended September 30, 1997 and 1998, respectively.

       Warranty Costs

       The Company provides for estimated warranty costs as products are
       shipped. Estimated warranty reserves are adjusted currently based upon
       projected levels of warranty repairs and estimated costs of materials,
       labor, and overhead costs to be incurred in meeting warranty obligations.

       Income Taxes

       Income taxes are accounted for under the asset-and-liability method.
       Deferred income tax assets and liabilities are computed annually for
       differences between the financial statement and tax bases of assets and
       liabilities that will result in taxable or deductible amounts in the
       future. Such deferred income tax asset-and-liability computations are
       based on enacted tax laws and rates. A valuation allowance is established
       when necessary to reduce deferred income tax assets to the amount
       expected to be realized.

(3)    SUMMARY OF ACCOUNTING PRINCIPLES, CONTINUED

       Loss Per Share

       Loss per share is calculated using the weighted average number of common
       shares outstanding during the year, adjusted for the assumed conversion
       of dilutive stock options and warrants. Since net losses were incurred in
       1997 and 1998, no conversion of dilutive stock options and warrants was
       assumed in the loss per share calculation in either year, as the effect
       would be anti-dilutive.

       Fair Value

       Financial instruments of the Company, consisting principally of cash,
       accounts receivable, accounts payable, and debt, are recorded at
       estimated fair value. The estimated fair value amounts have been
       determined by the Company, using available market information and
       available valuation methodologies.

       Use of Estimates

       Management of the Company has made a number of estimates and assumptions
       relating to the reporting of assets and liabilities and the disclosure of
       contingent assets and liabilities to prepare these consolidated financial
       statements in conformity with generally accepted accounting principles.
       Actual results could differ from those estimates. Estimates are used in
       the determination of the allowance for doubtful accounts, obsolete and
       slow moving inventory, capitalized software and related development
       costs, intangible assets, warranty costs, and deferred tax assets and
       liabilities.

       Other Recent Pronouncements

       In 1997, Statement of Financial Accounting Standards No. 130 ("SFAS
       130"), Reporting Comprehensive Income, was issued, and is effective for
       fiscal years commencing after December 15, 1997. The Company will comply
       with the requirements of SFAS 130 in fiscal year 1999.

       In 1997, Statement of Financial Accounting Standards No. 131 ("SFAS
       131"), Disclosures About Segments of an Enterprise and Related
       Information, was issued, and is effective for fiscal years commencing
       after December 15, 1997. The Company will comply with the requirements of
       SFAS 131 in fiscal year 1999.

       On October 27, 1997, the AICPA Accounting Standards Executive Committee
       issued Statement of Position 97-2 (SOP 97-2), Software Revenue
       Recognition. SOP 97-2 is effective for fiscal years commencing after
       December 15, 1997, and is not expected to impact the Company's financial
       position or results of operations. The Company will comply with the
       requirements of SOP 97-2 in fiscal year 1999.

(4)    ACQUISITIONS

       Merger with Intec Controls Corp.

       On March 31, 1997, the Company completed a merger of its wholly owned
       subsidiary, NemaSoft, Inc., with Intec Controls Corp. ("Intec"), a
       Walpole, Massachusetts-based developer of high-performance regulatory
       control software solutions used primarily by process industries. The
       Company recorded this transaction using the purchase method. The total
       purchase price was approximately $3,735,000, including expenses of
       approximately $430,000. Under terms of the merger agreement, the Company
       issued 587,594 shares of its common stock to the former Intec
       shareholders in exchange for 100 percent of the outstanding common stock
       of Intec. The Intec stock was retired, and NemaSoft is the surviving
       entity.

       In addition to the common stock issued, the Company issued warrants to
       the former Intec shareholders to purchase an additional 124,998 shares of
       Company common stock at $6.73 per share. The warrants expire February 20,
       2000.

       Merger with Virtual-Time Software, Inc.

       On June 20, 1997, the Company completed a merger of its wholly owned
       subsidiary, Imagination Systems, Inc., with Virtual-Time Software, Inc.
       ("VTS"), a Santa Clara, California-based developer of real-time operating
       system products which provide high-speed deterministic performance to
       MicroSoft's Windows (R) operating systems. The Company recorded this
       transaction using the purchase method. The total purchase price was
       approximately $694,000, including expenses of approximately $190,000.
       Under terms of the merger agreement, the Company issued 67,301 shares of
       its common stock and $100,000 to the former VTS shareholders in exchange
       for 100 percent of the outstanding common stock of VTS. The VTS stock was
       retired, and ISI is the surviving entity. In connection with the merger,
       ISI also entered into two-year employment and noncompetition agreements
       with VTS's president, who became an employee of ISI as a result of the
       merger.

       The allocation of total purchase price to assets acquired and liabilities
       assumed as of the respective purchase dates was as follows:

</TABLE>


       In the fourth quarters of fiscal 1997 and 1998, the Company wrote down
       certain software and related development costs, inventories and other
       intangible assets. In conjunction with the Company's strategic planning
       process, analyses were prepared to determine if any asset impairment
       existed as a result of changes to the Company's long-term strategic
       plans. These analyses indicated impairment existed due to lower or no
       planned revenues from certain products, and accordingly, assets related
       to these products were written off.

       In the fourth quarter of fiscal 1997 and in the third and fourth quarters
       of 1998, the Company wrote down certain purchased parts and accessories
       and finished goods inventories related to discontinued product models,
       pursuant to results of the Company's strategic planning process.

(5)    WRITE-DOWNS AND OTHER CHARGES, CONTINUED

       During the second quarter of fiscal 1997, the Company elected to close
       its Netherlands office and incurred closure costs of $245,836. Also in
       the second quarter, the Company obtained bank financing in order to repay
       its higher cost subordinated debt. A noncash charge of $122,340 was
       recorded, which relates to the write-off of deferred financing fees on
       the refinanced subordinated debt.

       During the fourth quarter of fiscal 1998, the Company announced that it
       had elected to close its software development offices in Virginia, Ohio
       and California and to consolidate the software development activities in
       its Massachusetts office. A provision for closing costs of $350,000 was
       recorded in connection with costs expected to occur resulting from such
       office closings.

(6)    RELATED PARTY TRANSACTIONS

       The Company leased its Virginia Beach, Virginia, office building from a
       partnership in which the former president and CEO of the Company is a
       partner. Total lease expense for the years ended September 30, 1997 and
       1998, under the terms of the lease were $79,600 and $82,600,
       respectively.

(8)    NOTE PAYABLE TO BANK

       The Company had a credit facility (the "Loan Agreement") with a bank
       providing for a Term Note, two Equipment Notes and a Revolving Credit
       Note. The Revolving Credit Note provided for a maximum borrowing by the
       Company of $6,000,000. The amount available under the line of credit was
       limited by a borrowing formula which allowed for advances up to a maximum
       of the sum of 80% of eligible domestic and foreign accounts, plus 35% of
       inventory. Based upon the borrowing formula, approximately $2,607,000 of
       the available line was eligible for advance at September 30, 1998,
       resulting in an over-advance position of $907,000 at that date. The line
       of credit is secured by substantially all assets of the Company and a
       second mortgage on the Company's Ann Arbor facility. The borrowings bore
       interest at the bank's prime interest rate (effective rate of 8.25% at
       September 30, 1998).

(8)    NOTE PAYABLE TO BANK, CONTINUED

       On September 28, 1998, and December 1, 1998 the Company entered into
       amendments to the loan agreements and into a Repayment Agreement with the
       bank which provided, among other things, for a modification of certain
       terms of the Term Note, two Equipment Notes and the Revolving Credit
       Note. The Revolving Credit Note, as amended contains various affirmative
       and negative covenants.  The Company is in violation of these covenants.

       Under the terms of the amended agreements, the amount available under the
       Revolving Credit Note is $5,000,000 and is limited by a borrowing formula
       which allows for advances up to a maximum of the sum of 80% of eligible
       domestic and foreign accounts, plus 35% of inventory, plus a Permitted
       Overadvance of $1,000,000 through January 31, 1999. The interest rate on
       the credit line borrowings is at the bank's prime interest rate plus 2%
       (10.25% effective rate at December 1, 1998). Amounts borrowed under the
       line of credit are due in full on January 31, 1999.

(9)    TRADE NOTES PAYABLE

       Trade notes payable consist of short-term notes payable to certain of the
       Company's creditors. The notes arose from the conversion in 1998 of
       $1,787,761 of trade notes payable and the payment against the notes in
       1998 of $241,805. The notes range in terms from six to twelve months in
       duration and generally are interest bearing at 12% per annum. The notes
       are classified as a current liability.

(10)   LONG-TERM DEBT

       Long-term debt consists of the following:

           monthly installments of $29,900 through September 2001, at which time
           the remaining principal and any interest thereon is due. The loan is
           collateralized by a first mortgage of the Company's land and building
           in Ann Arbor, Michigan                                                          $     1,998,509

(10)   LONG-TERM DEBT, CONTINUED

       The mortgage loan agreement contains covenants that require the Company
       to maintain a minimum tangible net worth and a minimum debt-to-equity
       ratio. As of September 30, 1998, the Company was not in compliance with
       these covenants; however, the Company's lender has waived these defaults
       through October 1, 1999.

       The loan agreement with the bank regarding the term note and two
       equipment notes includes various affirmative and negative covenants, the
       most restrictive of which are (1) the prohibition of dividend payments,
       and (2) requirements to maintain (a) a specified ratio of current assets
       to current liabilities, (b) a specified ratio of liabilities to tangible
       net worth, (c) a specified debt coverage ratio, and (d) a specified level
       of tangible worth. The Company was in violation of certain of these
       covenants at September 30, 1998 and as such these notes totaling
       $1,579,781 are included in current maturities of long-term debt.

       The aggregate amounts of long-term debt maturities at September 30, 1998,

(11)   TAXES ON INCOME, CONTINUED

       Deferred income taxes result from temporary differences in the
       recognition of income and expenses for financial and income tax reporting
       purposes. Deferred income taxes are primarily due to the use of
       accelerated methods of depreciation for tax purposes versus principally
       straight-line methods for financial reporting purposes, the
       capitalization of software development costs for financial reporting
       purposes versus the expensing of these items as incurred for tax
       purposes, inventory reserves deductible for tax purposes when disposed of

</TABLE>


       During the years ended September 30, 1997 and 1998, the valuation
       allowance increased by $3,786,000 and $2,112,000, respectively. At
       September 30, 1998, the Company has net operating loss carryforwards of
       approximately $19,400,000, which expire at various dates between 2003 and
       2013. Utilization of these carryforwards is subject to annual limitations
       under current IRS regulations. The Company has established a valuation
       allowance for the estimated amount of the total limitation on the
       utilization of the net operating loss carryforwards. Realization of net
       deferred tax assets associated with the net operating loss carryforwards
       is dependent upon generating sufficient taxable income prior to their
       expiration. Although realization is not assured for the net deferred tax
       assets, management believes it is more likely than not that they will be
       realized through future taxable earnings or alternative tax strategies.
       However, the net deferred tax assets could be reduced in the near term if
       management's estimates of future taxable income are no longer viable.

(12)   EMPLOYEE BENEFIT PLANS

       1993 Stock Option Plan

       The Company's 1993 Stock Option Plan (the "1993 Plan") provides for the
       granting of options to purchase a total of 950,000 shares of common stock
       to key employees. The exercise price for each option granted under the
       1993 Plan cannot be less than the fair market value of the common stock
       on the date of the grant.

       The 1993 Plan gives the Compensation Committee of the Board of Directors
       latitude in deciding the vesting period. Options generally vest one third
       immediately and one third on each successive anniversary date of the
       award, or are exercisable at the rate of one third per year beginning on
       the day after the first anniversary of the date of the award. Under
       provisions of the 1993 Plan, shares subject to an option award will
       become immediately exercisable upon a change in control of the Company.
       Options remaining unexercised on the tenth anniversary of the date of the
       grant will expire. No options may be granted after February 26, 2003.

       As of September 30, 1998, an additional 56,503 options may be issued
       under the 1993 Plan.

       Directors Option Plan

       The Company's 1993 Directors Stock Option Plan (the "Directors Option
       Plan") provides for the granting of options to purchase a total of
       120,000 shares of common stock. The exercise price for each option
       granted beginning April 1997 under the Directors Option Plan is equal to
       110 percent of the closing price of the stock on the grant date. The
       exercise price for options granted prior to April 1997 was the greater of
       the fair market value or book value of the Company's common stock on the
       date of the grant.

       The Directors Option Plan provides that beginning April 1997, each
       qualified director will be granted annually an option to purchase 4,500
       shares of common stock. Prior to April 1997, each qualified director was
       granted annually an option to purchase 1,000 shares of common stock.
       Options granted in April 1997 or thereafter will be exercisable in
       one-third increments beginning on the date of the grant. Options granted
       prior to April 1997 are exercisable at any time beginning six months
       after the date of the grant. Options expire five years from the date of
       the grant. As of September 30, 1998, an additional 24,680 options may be
       issued under the Directors Option Plan.

       Special Option Grants

       The Board of Directors, in fiscal 1995, 1996 and 1997, awarded special
       option grants to a former chairman and a former Board member. The awards
       were made separate from either of the two qualified plans specified
       above.

       The fair values of options granted during 1997 and 1998 were determined
using the Black-Scholes option-pricing model based on the following assumptions:

</TABLE>


       401(k) Plan and Trust

       The Company has established a defined-contribution retirement plan for
       all eligible employees. Participants may make basic contributions of up
       to 15 percent of their compensation, pursuant to section 401(k) of the
       Internal Revenue Code. Under terms of the 401(k) plan, the Company may
       make a basic contribution and a discretionary contribution to the plan.
       In fiscal 1997 and through March 1998, the Company contributed 100% of
       each employee's contribution up to the first 5% of the employee's base
       salary contributed by the employee. In April and May, the Company reduced
       its contribution to 3%, and beginning in June, contributions were
       discontinued. A participant becomes vested in the Company's contribution
       on his or her behalf at a rate of 20 percent for each year of service
       after the effective date of the 401(k) plan.

       Notwithstanding the foregoing, a participating employee will be fully
       vested in the Company's contributions to his or her account in the event
       of death, or in the event of disability or normal retirement, as those
       terms will be defined in the 401(k) plan. The Company's contributions to
       the 401(k) plan were approximately $158,000 and $38,000 for the years
       ended September 30, 1997 and 1998, respectively.

       Total rental expense in fiscal 1997 and 1998 was approximately $308,000
       and $245,000, respectively.

       On May 8, 1998, a lawsuit was filed against the Company in the District
       Court for the Southern District of New York. The lawsuit names as
       defendants the Company, certain of its officers and directors, its former
       independent auditor and the underwriter for the Company's initial public
       offering. The plaintiff seeks to represent a class of shareholder who
       purchased the Company's common stock from January 31, 1996 through April
       28, 1998. An amended complaint filed by the plaintiff in October 1998
       claims violations of securities laws and common law based on allegations
       that defendants made untrue statements of material facts and that they
       omitted material facts necessary in order to make the statements not
       misleading. The complaint seeks unspecified damages and costs. In
       December 1998, the case was transferred to the Michigan District.
       Management believes that the outcome of this case will not have a
       material adverse effect on the Company.

         m)       No Interference with Other Agreements or Contracts. Neither
                  the execution of this Repayment Agreement nor the consummation
                  of the transactions contemplated hereby will constitute a
                  violation of, be in conflict with or constitute a default

                  both, would constitute a default under) any material term or
                  provision of any other agreement, contract, lease or
                  instrument to which any Interested Party is a party or by
                  which any Interested Party (or the assets of any Interested
                  Party) is bound, or which affects or relates to the Collateral

                  in any other state where Borrower is required to qualify to do
                  business in such state except where the failure to so qualify
                  would have a material adverse effect upon the Collateral or
                  the operations of Borrower.

         by the Original Notes shall be restructured pursuant to the terms of

         Notes and any of the Loan Documents which for any reason in fact or in

         intended by the parties hereto. In connection with the restructure of
         the Obligations, the following amendments are hereby made to the Loan
         Agreement:

         a)       Appointment of a Receiver. Without notice to any Interested
                  Party or any party claiming under them (such notice being
                  hereby expressly waived) and without reference to the value of

                  referred to in this Repayment Agreement, Borrower and all
                  other Interested Parties consent to the immediate appointment,
                  whether by the Bank or pursuant to the order of any Court, of
                  a receiver for all or any of the Collateral which secures all
                  or part of the Obligations, and further agrees to take all
                  necessary steps to immediately, completely and effectively
                  transfer all of its right, title and interest in the
                  Collateral to any such receiver, including, without

                  receiver shall be vested with the power to take immediate
                  possession of the Collateral, to manage the assets and
                  business of Borrower, and to collect any and all rents,
                  issues, profits, accounts or Proceeds of the assets of
                  Borrower, and any and all such rents, issues, profits,

                  payment of the Obligations, and the costs, attorneys fees,

                  and preservation of the Collateral, including the expenses of

                  Collateral as promptly as is commercially reasonable, subject
                  to court approval, and shall apply the Proceeds of sale
                  against the Borrower's Obligations owed to the Bank in such
                  order and by such division as Bank shall elect.

         b)       Other Remedies. The Bank may exercise all or any other

         exoneration, contribution, indemnification, and any right to
         participate in any claim or remedy of Bank against Borrower or any of
         the Collateral, whether or not such claim, remedy, or right arises in
         equity, or under contract, statute, or common law.

12.      Time is of the Essence. The Interested Parties further acknowledge that
         TIME IS OF THE ESSENCE with respect to the time for performance of the
         terms and provisions of this Repayment Agreement. None of the
         Interested Parties shall be given any grace period within which to cure
         any default or breach under this Repayment Agreement.

13.      No Duress; Each Party Advised by Counsel; Traditional Rule of
         Construction Not Applicable. The Interested Parties stipulate and agree
         that the Loan Documents and this Repayment Agreement have been executed
         voluntarily after due deliberation and negotiation and that neither
         Bank nor any other person has exerted or attempted to exert improper or
         unlawful pressure or has in any way induced or attempted to induce,
         through threats or otherwise, any conduct on the part of the Interested
         Parties including the execution or delivery of this Repayment Agreement
         or any of the Loan documents or any other document or instrument.
         Without in any way limiting the foregoing, each of the parties hereto
         stipulate and agree that at all times during the course of the
         negotiations resulting in the execution and delivery of this Repayment
         Agreement, they have, to the 


                                       21
<PAGE>   22

         extent deemed necessary or advisable in their sole discretion, been
         advised and assisted by competent counsel of their own choosing.
         Because this Repayment Agreement was negotiated at length with counsel,
         the parties agree that the traditional rules calling for a document to
         be construed against its draftsman shall not apply or be followed.

14.      RELEASE. EFFECTIVE AS OF THE DATE OF THE EXECUTION AND DELIVERY OF
         THIS REPAYMENT AGREEMENT, THE INTERESTED PARTIES JOINTLY AND SEVERALLY
         AGREE TO RELEASE AND HEREBY DO RELEASE AND DISCHARGE, BANK, ITS

         DAMAGES, LOSSES, CLAIMS, DEMANDS, LIABILITIES, OBLIGATIONS, ACTIONS AND
         CAUSES OF ACTION WHATSOEVER THAT EACH INTERESTED PARTY HAS OR CLAIMS TO
         HAVE AGAINST ANY BANK PARTY AS OF THE DATE HEREOF AND WHETHER KNOWN OR
         UNKNOWN AT THE TIME OF THIS RELEASE, AND OF EVERY NATURE AND EXTENT

         TOUCHING, CONCERNING, ARISING OUT OF OR FOUNDED UPON THE LOAN DOCUMENTS
         OR THE LENDING RELATIONSHIP RESPECTING THE OBLIGATIONS BETWEEN ANY
         INTERESTED PARTY AND ANY BANK PARTY. THIS RELEASE WILL NOT EXTEND TO

         DATE OF THIS REPAYMENT AGREEMENT EXCEPT THAT SUCH RELEASE IS
         SPECIFICALLY INTENDED BY THE PARTIES TO INCLUDE THE TRANSACTIONS
         CONTEMPLATED BY THIS REPAYMENT AGREEMENT. Bank would not agree to enter
         into this Repayment Agreement but for the provisions set forth in this
         Section 14. The Interested Parties confirm that they have agreed to the
         provisions of this Section 14 of their own volition, with full
         knowledge of the extent and effect of the various releases and waivers
         granted by this Section 14 and of the importance to Bank of these
         waivers and releases and after having had the opportunity to discuss
         this matter with counsel of their own choice.

         BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY ANY PARTY
         AGAINST ANOTHER ON ANY MATTERS WHATSOEVER ARISING UNDER OR IN

         ANCILLARY AGREEMENT AND SHALL TAKE ALL APPROPRIATE STEPS TO IMPLEMENT
         THAT WAIVER, INCLUDING PROVIDING FURTHER WRITTEN CONSENT IN COURT.

16.      Loan Documents. Except as herein specifically provided otherwise, the
         Original Loan Documents shall remain in full force and effect and be
         unaffected hereby. In the event of 


                                       22
<PAGE>   23

         a conflict between the terms of this Repayment Agreement, the Loan
         Documents and any other agreement between the Bank and the Borrower or
         any other Interested Party, then this Repayment Agreement shall be
         controlling. The within Repayment Agreement and all writings delivered

         by any party hereto to exercise any right or remedy upon the happening

         Agreement and supersedes all prior and contemporaneous negotiations,

<PAGE>   26
         provision of the Repayment Agreement, and the Repayment Agreement shall

                   AMENDED AND RESTATED REVOLVING CREDIT NOTE


$6,000,000.00                                     Dated as of September 28, 1998
                                                             Ann Arbor, Michigan


         On October 31, 1998, for value received, the undersigned (herein called
the "Borrower") promises to pay to the order of KEYBANK NATIONAL ASSOCIATION, a
national banking association (herein called the "Bank"), at its main office, in
good and collected funds, the principal sum of Six Million and 00/100 Dollars
($6,000,000.00) with interest from the date of the Note until October 31, 1998,
at a floating rate per annum of one-quarter of one percent (.25%) in excess of
the Prime Rate of the Bank in effect from time to time, but not to exceed the
maximum rate permitted by law, payable October 1, 1998, and at maturity,
computed on the principal sum hereof remaining from time to time unpaid. In the
event of any change in the Prime Rate of Bank, the interest rate on this Amended
Note shall be immediately and correspondingly adjusted, but in no event shall
the interest rate on this Amended Note prior to maturity exceed the highest rate
permitted by law on the date of this Amended Note. The Prime Rate of Bank is
defined as that rate established from time to time by Bank as Bank's Prime Rate,
whether or not such rate is publicly announced; the Prime Rate may not be the
lowest interest rate charged by Bank for commercial or other extensions of
credit. After maturity or the occurrence of an Event of Default, the unpaid
principal and accrued interest on this Amended Note shall, until paid, bear
interest at a rate per annum equal to the greater of four percent (4%) in excess
of the Prime Rate, which rate shall be immediately and correspondingly adjusted
with each change in the Prime Rate, or sixteen percent (16%); but in no event
shall the interest rate on this Amended Note after maturity exceed the highest
rate permitted by law on the date of maturity.

         Prior to maturity, if any payment of principal or interest is not paid
when due, Borrower shall pay Bank a late fee equal to the greater of ten percent
(10%) of the amount of such payment or twenty five dollars ($25).

         Borrower may prepay this Amended Note, in whole or in part, without the
payment of any premium, but all such payments shall be applied to the principal
installments of this Amended Note in the inverse order of their maturity.

         This Amended Note is issued pursuant to a certain Repayment Agreement
executed on even date herewith by and between Borrower and Bank, among others
(said Repayment Agreement as it may be from time to time amended, restated or
otherwise modified being herein called the "Repayment Agreement") to which
reference is hereby made for a statement of the rights of Bank and the duties
and obligations of Borrower in relation thereto, but neither this reference to
the Repayment Agreement nor any provision thereof shall affect or impair the
absolute and unconditional obligation of Borrower to pay the principal of and
interest on this Amended Note when due. This Amended Note amends and restates in
its entirety the Revolving Credit Note dated February 12, 1997 in the principal
amount of $6,000,000.00, including any 

                                       1
<PAGE>   2

amendments or modifications thereto, and referred to in the Repayment Agreement
and does not represent evidence of new indebtedness, or repayment of any
indebtedness. The notes which formerly evidenced the debt now evidenced by this
Amended Note shall remain in full force and effect only for the purpose of
evidencing any amounts due thereunder which for any reason, in fact or in law,
that do not become obligations of the Borrower under this Amended Note as
intended by the Borrower. Capitalized terms used herein and not defined shall
have the meaning given to them in the Repayment Agreement. The headings of
paragraphs of the Repayment Agreement and the titles of any and all documents
executed in conjunction therewith, including this Amended Note, are for the
convenience of reference only, and are not to be considered as limiting or
otherwise affecting any of the terms hereof or thereof.

         This Amended Note and every other obligation, indebtedness, and
liability of Borrower to Bank, whether joint or several, absolute or contingent,
due or to become due, and whether heretofore or hereafter contracted or existing
and in whatsoever manner acquired by or accruing to Bank, whether before or
after maturity and whether the same may have been or shall be participated, in
whole or in part to others, and including all amendments, extensions, and
renewals thereof (all herein called "Obligations"), are secured as set forth in
the Repayment Agreement.

         Borrower represents and warrants that it is a duly-organized and
existing corporation under the laws of the State of Michigan that the execution
and delivery hereof have been duly authorized by appropriate corporate action,
that there is no prohibition either in law, in its articles of incorporation,
by-laws, or regulations, or in any agreement to which it is a party which in any
way restricts or prevents the execution of this Amended Note and performance of
the Obligations herein in any respect, and that this Amended Note has been duly
executed and is a valid and binding Obligation of Borrower.

         Borrower shall be in default hereunder if there shall occur an Event of
Default as set forth in the Repayment Agreement. If there shall occur any Event
of Default, Bank, by notice given to Borrower (only if and to the extent such
notice is required by the Repayment Agreement), may declare the unpaid principal
of and accrued interest owing upon this Amended Note and all other Obligations
to be immediately due and payable and upon any such declaration such principal
and interest shall become and be forthwith due and payable without any further
notice, presentment, or demand of any kind, all of which are hereby expressly
waived by Borrower. Further as provided in the Repayment Agreement for specific
Events of Default, the unpaid principal and accrued interest owing upon this
Amended Note and all other Obligations shall become and be forthwith due and
payable without declaration, notice, presentment, or demand of any kind, all of
which are hereby expressly waived by Borrower.

         Wherever used in this Amended Note, the term "Bank" shall include any
holder or assignee of this Amended Note. Except for notice expressly required by
the Repayment Agreement, if any, Borrower and each endorser, guarantor, and
surety hereof waives presentment, demand for payment, protest, notice of
protest, and notice of nonpayment, and further agrees and consents that, without
notice and without affecting their liability hereon, the holder hereof at any
time or times is authorized to: (a) correct patent errors and fill blanks
herein; (b) cause or permit the signature of one or more additional makers,
co-makers, sureties, guarantors and/or endorsers to be added hereto; (c) extend
the time of payment of this Amended Note in whole or in part; (d) sell,
exchange, surrender, substitute or otherwise deal with any

collateral now or hereafter securing this Amended Note; (e) add or release any
other person primarily or secondarily liable on this Amended Note; and (f)
modify, waive, supplement or otherwise change the terms of any security
agreement pertaining to this Amended Note.

         Borrower understands and agrees that this Amended Note is subject to
and shall be construed according to the laws of the State of Ohio, without
regard to principles of conflict of laws. Bank's rights, remedies, and powers
that are expressly specified in this Amended Note are in addition to Bank's
rights, remedies, and powers under any other instrument or agreement or under
applicable law.

         Any deposits or sums at any time credited by or due from Bank to
Borrower and any securities or other personal property of Borrower in the
possession of Bank may at all times be held and treated as additional security
for the payment of the Obligations. After the occurrence of any Event of
Default, Bank may apply or set off such deposits or other sums against the
Obligations at any time and without further notice.

         Any waiver of Bank's rights hereunder must be in writing and signed by
Bank. A waiver on any one or more occasions shall not be construed as a bar to
or waiver of any such right or remedy on a future occasion, nor as the
establishment of a course of dealing with respect to such waiver(s) or any other
action or inaction of Bank referred to in this paragraph. Delay or failure by
Bank to exercise its powers, rights, or remedies, in whole or in part, shall not
be deemed a waiver of any such power, right, or remedy; no single or partial
exercise of any right, power, or remedy hereunder shall preclude the exercise of
any other right, power, or remedy. All agreements, representations, and
warranties made herein will survive the making of the loan evidenced by this
Amended Note and will bind and inure to the benefit of Borrower and its
successors and assigns and Bank and its successors and assigns.

         Any notice required or authorized to be given to Borrower pursuant to
the provisions of this Amended Note shall be sufficiently given when such notice
is either delivered, sent by telegram, or mailed (deposited for delivery,
postage prepaid, by U.S. mail) to Borrower either at the address set forth below
(as modified by any change therein which Borrower has supplied in writing to
Bank) or at any other address at which Bank customarily communicates with
Borrower.

         If any provision of this Amended Note, or any covenant, stipulation,
obligation, agreement, act, or action, or part thereof made, assumed, entered
into, or taken hereunder or any application thereof, is for any reason held to
be illegal or invalid, such illegality or invalidity shall not affect any other
provision or any other covenant, stipulation, obligation, agreement, act, or
action or part thereof, made, assumed, entered into, or taken, each of which
shall be construed and enforced as if such illegal or invalid portion were not
contained herein. Such illegality or invalidity of any application of any
provision hereof shall not affect any legal and valid application thereof, and
each such provision, covenant, stipulation, obligation, agreement, act, or
action, or part shall be deemed to be effective, operative, made, entered into,
or taken in the manner and to the full extent permitted by law.

         The relationship between Borrower and Bank with respect to this Amended
Note and any writing executed or delivered in connection herewith is and shall
be solely that of debtor and 

                                       3
<PAGE>   4
creditor, respectively, and Bank has no fiduciary obligation toward Borrower
with respect to any such document or the transactions contemplated thereby.

         This Amended Note and any agreement, document or instrument referred to
herein or executed between Bank and Borrower on or as of the date hereof
integrate all of the terms and conditions mentioned herein or incidental hereto
and supersede all oral representations and negotiations and prior writings with
respect to the subject matter hereof.

         Borrower agrees to promptly reimburse Bank for all costs and expenses,
including attorney's fees of Bank's in-house or outside counsel incurred by Bank
in connection with any restructurings of this Amended Note or any documents
executed and delivered in connection herewith and in connection with any
collection proceedings as a result of nonpayment of this Amended Note, as and
when due and payable.

         Borrower has received consideration which is the reasonable equivalent
value of the obligations and liabilities that Borrower has incurred to Bank.
Borrower is not insolvent as defined in any applicable state or federal statute,
nor will Borrower be rendered insolvent by the execution and delivery of this
Amended Note to Bank. Borrower is not engaged or about to engage in any business
or transaction for which the assets retained by it shall be an unreasonably
small capital, taking into consideration the obligations to Bank incurred
hereunder. Borrower does not intend to, nor does it believe that it will, incur
debts beyond its ability to pay them as they mature.

         Borrower, to the extent permitted by law, waives any right to have a
jury participate in resolving any dispute, whether sounding in contract, tort,
or otherwise, between Bank and Borrower arising out of, in connection with,
related to, or incidental to the relationship established between Borrower and
Bank in connection with this Amended Note or any other agreement, instrument or
document executed or delivered in connection therewith or the transactions
related thereto. This waiver shall not in any way affect, waive, limit, amend or
modify Bank's ability to pursue remedies pursuant to any confession of judgment
or cognovit provision contained in this Amended Note, or any other agreement,
instrument or document related thereto.

                         AMENDED AND RESTATED TERM NOTE

$1,230,000.00                                     Dated as of September 28, 1998
                                                             Ann Arbor, Michigan

         For value received, the undersigned (herein called "Borrower") promises
to pay to the order of KEYBANK NATIONAL ASSOCIATION, Cleveland, Ohio (herein
called "Bank"), in good and collected funds, at its main office, the principal
sum of One Million Two Hundred Thirty Thousand and 00/100 Dollars
($1,230,000.00) in one (1) monthly installment of Thirty Thousand and 00/100
Dollars ($30,000.00) on October 1, 1998, plus one (1) final installment on
October 31, 1998 of any remaining principal balance shall be due and payable,
together with interest upon any unpaid principal balance computed upon a 360 day
basis and payable on each date designated above for principal payments and at
maturity, at a floating rate per annum of one-half of one percent (.5%) in
excess of the Prime Rate of Bank. In the event of any change in the Prime Rate
of Bank, the interest rate on this Amended Note shall be immediately and
correspondingly adjusted, but in no event shall the interest rate on this
Amended Note prior to maturity exceed the highest rate permitted by law on the
date of this Amended Note. The Prime Rate of Bank is defined as that rate
established from time to time by Bank as Bank's Prime Rate, whether or not such
rate is publicly announced; the Prime Rate may not be the lowest interest rate
charged by Bank for commercial or other extensions of credit. After maturity or
the occurrence of an Event of Default, the unpaid principal and accrued interest
on this Amended Note shall, until paid, bear interest at a rate per annum equal
to the greater of four percent (4%) in excess of the Prime Rate, which rate
shall be immediately and correspondingly adjusted with each change in the Prime
Rate, or sixteen percent (16%); but in no event shall the interest rate on this
Amended Note after maturity exceed the highest rate permitted by law on the date
of maturity.

         Prior to maturity, if any payment of principal or interest is not paid
when due, Borrower shall pay Bank a late fee equal to the greater of ten percent
(10%) of the amount of such payment or twenty five dollars ($25).

         Borrower may prepay this Amended Note, in whole or in part, without the
payment of any premium, but all such payments shall be applied to the principal
installments of this Amended Note in the inverse order of their maturity.

         This Amended Note is issued pursuant to a certain Repayment Agreement
executed on even date herewith by and between Borrower and Bank, among others
(said Repayment Agreement as it may be from time to time amended, restated or
otherwise modified being herein called the "Repayment Agreement") to which
reference is hereby made for a statement of the rights of Bank and the duties
and obligations of Borrower in relation thereto, but neither this reference to
the Repayment Agreement nor any provision thereof shall affect or impair the
absolute and unconditional obligation of Borrower to pay the principal of and
interest on this Amended Note when due. This Amended Note amends and restates in
its entirety the Term Note dated February 12, 1997 in the principal amount of
$1,800,000.00, including any amendments or modifications thereto, and referred
to in the Repayment Agreement and does not represent

                                        5
<PAGE>   2

evidence of new indebtedness, or repayment of any indebtedness. The notes which
formerly evidenced the debt now evidenced by this Amended Note shall remain in
full force and effect only for the purpose of evidencing any amounts due
thereunder which for any reason, in fact or in law, that do not become
obligations of the Borrower under this Amended Note as intended by the Borrower.
Capitalized terms used herein and not defined shall have the meaning given to
them in the Repayment Agreement. The headings of paragraphs of the Repayment
Agreement and the titles of any and all documents executed in conjunction
therewith, including this Amended Note, are for the convenience of reference
only, and are not to be considered as limiting or otherwise affecting any of the
terms hereof or thereof.

         This Amended Note and every other obligation, indebtedness, and
liability of Borrower to Bank, whether joint or several, absolute or contingent,
due or to become due, and whether heretofore or hereafter contracted or existing
and in whatsoever manner acquired by or accruing to Bank, whether before or
after maturity and whether the same may have been or shall be participated, in
whole or in part to others, and including all amendments, extensions, and
renewals thereof (all herein called "Obligations"), are secured as set forth in
the Repayment Agreement.

         Borrower represents and warrants that it is a duly-organized and
existing corporation under the laws of the State of Michigan that the execution
and delivery hereof have been duly authorized by appropriate corporate action,
that there is no prohibition either in law, in its articles of incorporation,
by-laws, or regulations, or in any agreement to which it is a party which in any
way restricts or prevents the execution of this Amended Note and performance of
the Obligations herein in any respect, and that this Amended Note has been duly
executed and is a valid and binding Obligation of Borrower.

         Borrower shall be in default hereunder if there shall occur an Event of
Default as set forth in the Repayment Agreement. If there shall occur any Event
of Default, Bank, by notice given to Borrower (only if and to the extent such
notice is required by the Repayment Agreement), may declare the unpaid principal
of and accrued interest owing upon this Amended Note and all other Obligations
to be immediately due and payable and upon any such declaration such principal
and interest shall become and be forthwith due and payable without any further
notice, presentment, or demand of any kind, all of which are hereby expressly
waived by Borrower. Further as provided in the Repayment Agreement for specific
Events of Default, the unpaid principal and accrued interest owing upon this
Amended Note and all other Obligations shall become and be forthwith due and
payable without declaration, notice, presentment, or demand of any kind, all of
which are hereby expressly waived by Borrower.

         Wherever used in this Amended Note, the term "Bank" shall include any
holder or assignee of this Amended Note. Except for notice expressly required by
the Repayment Agreement, if any, Borrower and each endorser, guarantor, and
surety hereof waives presentment, demand for payment, protest, notice of
protest, and notice of nonpayment, and further agrees and consents that, without
notice and without affecting their liability hereon, the holder hereof at any
time or times is authorized to: (a) correct patent errors and fill blanks
herein; (b) cause or permit the signature of one or more additional makers,
co-makers, sureties, guarantors and/or endorsers to be added hereto; (c) extend
the time of payment of this Amended Note in whole or in part; (d) sell,
exchange, surrender, substitute or otherwise deal with any collateral now or
hereafter securing this Amended Note; (e) add or release any other person

                                       6

primarily or secondarily liable on this Amended Note; and (f) modify, waive,
supplement or otherwise change the terms of any security agreement pertaining to
this Amended Note.

         Borrower understands and agrees that this Amended Note is subject to
and shall be construed according to the laws of the State of Ohio, without
regard to principles of conflict of laws. Bank's rights, remedies, and powers
that are expressly specified in this Amended Note are in addition to Bank's
rights, remedies, and powers under any other instrument or agreement or under
applicable law.

         Any deposits or sums at any time credited by or due from Bank to
Borrower and any securities or other personal property of Borrower in the
possession of Bank may at all times be held and treated as additional security
for the payment of the Obligations. After the occurrence of any Event of
Default, Bank may apply or set off such deposits or other sums against the
Obligations at any time and without further notice.

         Any waiver of Bank's rights hereunder must be in writing and signed by
Bank. A waiver on any one or more occasions shall not be construed as a bar to
or waiver of any such right or remedy on a future occasion, nor as the
establishment of a course of dealing with respect to such waiver(s) or any other
action or inaction of Bank referred to in this paragraph. Delay or failure by
Bank to exercise its powers, rights, or remedies, in whole or in part, shall not
be deemed a waiver of any such power, right, or remedy; no single or partial
exercise of any right, power, or remedy hereunder shall preclude the exercise of
any other right, power, or remedy. All agreements, representations, and
warranties made herein will survive the making of the loan evidenced by this
Amended Note and will bind and inure to the benefit of Borrower and its
successors and assigns and Bank and its successors and assigns.

         Any notice required or authorized to be given to Borrower pursuant to
the provisions of this Amended Note shall be sufficiently given when such notice
is either delivered, sent by telegram, or mailed (deposited for delivery,
postage prepaid, by U.S. mail) to Borrower either at the address set forth below
(as modified by any change therein which Borrower has supplied in writing to
Bank) or at any other address at which Bank customarily communicates with
Borrower.

         If any provision of this Amended Note, or any covenant, stipulation,
obligation, agreement, act, or action, or part thereof made, assumed, entered
into, or taken hereunder or any application thereof, is for any reason held to
be illegal or invalid, such illegality or invalidity shall not affect any other
provision or any other covenant, stipulation, obligation, agreement, act, or
action or part thereof, made, assumed, entered into, or taken, each of which
shall be construed and enforced as if such illegal or invalid portion were not
contained herein. Such illegality or invalidity of any application of any
provision hereof shall not affect any legal and valid application thereof, and
each such provision, covenant, stipulation, obligation, agreement, act, or
action, or part shall be deemed to be effective, operative, made, entered into,
or taken in the manner and to the full extent permitted by law.

         The relationship between Borrower and Bank with respect to this Amended
Note and any writing executed or delivered in connection herewith is and shall
be solely that of debtor and creditor, respectively, and Bank has no fiduciary
obligation toward Borrower with respect to any such document or the transactions
contemplated thereby.

                           deleted in its entirety, and the following inserted
                           in lieu thereof:

                                    long as no Event of Default under this
                                    Agreement has occurred or is continuing,
                                    Bank shall make cash advances to Borrower in

                                    vii)    The Repayment Agreement is amended 
         by deleting the prefatory paragraph of Section 17, and inserting in
         lieu thereof the following:

                         Notices.   Any notice, demand or communication required
                                    or permitted to be given by any provision of
                                    this Repayment Agreement will be in writing
                                    and will be deemed to have been given when
                                    delivered personally or by facsimile,
                                    receipt confirmed, to the party designated
                                    to receive such notice, or on the date
                                    following the day sent by overnight courier,
                                    or on the third (3rd) business day after the
                                    same is sent by certified mail, postage and
                                    charges prepaid, directed to the following
                                    addresses or to such other or additional
                                    addresses as any party might designate by
                                    written notice to the other party; provided,
                                    however, that in the event that Bank
                                    determines to cease making advances under
                                    Borrower's line of credit, Bank shall
                                    undertake to promptly so notify Borrower by
                                    both facsimile and overnight courier, though
                                    Bank's determination to cease providing
                                    advances shall be effective when made, and
                                    shall not be dependent upon Borrower's
                                    receipt of notice.

                           viii) The Repayment Agreement is amended by deleting
               Exhibits B, C and D, and replacing them with Exhibits B, C and D
               in the form of Annexes 1 through 3, respectively, attached
               hereto.
                           ix) The Repayment Agreement is amended by adding new
               Exhibits I-1 through I-4 in the form of Annex 4-A through 4-D

of the terms and conditions of this First Amendment are inconsistent with the

<PAGE>   7

         6.    Course of Dealing. The parties hereto recognize that Borrower has
not fully complied with the terms of the Loan Documents. No course of dealing
between the parties is established by virtue of Borrower's non-compliance
therewith and Bank's failure exercise its legal rights responsive thereto.
Interested Parties understand that the Loan Documents will be strictly enforced
going forward, and that Bank's failure to insist on strict performance to date
shall not be interposed as a defense to Bank's exercise of its legal rights, nor
shall it constitute a waiver of any thereof.

executed copy or original of this First Amendment, the Interested Parties
jointly and severally agree to release and hereby do release and discharge,

actions and causes of action whatsoever that each Interested Party has or claims
to have against any Bank Party as of the date hereof and whether known or

arising out of or founded upon the Loan Documents, or the relationship
respecting any agreement between any Interested Party and any Bank Party.

         8.    Third-Party Beneficiaries/Entire Agreement. All the conditions 
and obligations hereunder are imposed solely and exclusively for the benefit of
the parties hereto and their successors and assigns. No other person or entity
shall obtain any interest herein or require satisfaction of such conditions in
accordance with the terms hereof or be entitled to assume that any of the
parties hereto will enforce such conditions and obligations and no other person
shall, under any circumstances, be a beneficiary of such conditions. This First
Amendment embodies the entire agreement and understanding between the parties
hereto with respect to the subject matter of this First Amendment and supersedes
all prior and contemporaneous negotiations, agreements and understandings
relative to such subject matter.

         9.    Binding Effect; Governing Law. This First Amendment shall bind 
and inure to the benefit of the parties hereto and their respective successors
and assigns and shall be governed by and construed in accordance with the laws
of the State of Michigan without regard to principles of conflict of laws.

         10.   Counterparts. This First Amendment may be executed in any number
of counterparts, each of which, when so executed and delivered, shall be an
original and all of which counterparts together shall constitute one and the
same fully executed instrument.

remains in full force and effect.

         12.   Corporate Authority. Borrower and Guarantor hereby represent and
warrant to Bank that (a) Borrower and Guarantor have the legal power and
authority to execute and deliver this First Amendment; (b) the officials

                                       7
<PAGE>   8

provisions hereof; (c) the execution and delivery hereof by Borrower and
Guarantor and the performance and observance by Borrower and Guarantor of the
provisions hereof do not violate or conflict with the organizational agreements
of Borrower or Guarantor or any law applicable to Borrower or Guarantor or
result in a breach of any provision of or constitute a default under any other
agreement, instrument or document binding upon or enforceable against Borrower
or Guarantor; (d) this First Amendment constitutes a valid and binding

                SECOND AMENDED AND RESTATED REVOLVING CREDIT NOTE


$5,000,000.00                                       Dated as of December 1, 1998
                                                             Ann Arbor, Michigan


         On January 31, 1999, for value received, the undersigned (herein called
the "Borrower") promises to pay to the order of KEYBANK NATIONAL ASSOCIATION, a
national banking association (herein called the "Bank"), at its main office, in
good and collected funds, the principal sum of Five Million and 00/100 Dollars
($5,000,000.00) with interest from the date of the Note until January 31, 1999,
at a floating rate per annum of two percent (2%) in excess of the Prime Rate of
the Bank in effect from time to time, but not to exceed the maximum rate
permitted by law, payable on the first day of each month, and at maturity,
computed on the principal sum hereof remaining from time to time unpaid. In the
event of any change in the Prime Rate of Bank, the interest rate on this Amended
Note shall be immediately and correspondingly adjusted, but in no event shall
the interest rate on this Amended Note prior to maturity exceed the highest rate
permitted by law on the date of this Amended Note. The Prime Rate of Bank is
defined as that rate established from time to time by Bank as Bank's Prime Rate,
whether or not such rate is publicly announced; the Prime Rate may not be the
lowest interest rate charged by Bank for commercial or other extensions of
credit. After maturity or the occurrence of an Event of Default, the unpaid
principal and accrued interest on this Amended Note shall, until paid, bear
interest at a rate per annum equal to the greater of four percent (4%) in excess
of the Prime Rate, which rate shall be immediately and correspondingly adjusted
with each change in the Prime Rate, or sixteen percent (16%); but in no event
shall the interest rate on this Amended Note after maturity exceed the highest
rate permitted by law on the date of maturity.

         Borrower may prepay this Amended Note, in whole or in part, without the
payment of any premium, but all such payments shall be applied to the principal
installments of this Amended Note in the inverse order of their maturity.

         This Amended Note is issued pursuant to a certain Repayment Agreement
executed on September 28, 1998, as amended by a First Amendment to Repayment
Agreement and Fourth Amendment to Loan Agreement of even date herewith by and
between Borrower and Bank, among others (said Repayment Agreement as it may be
from time to time amended, restated or otherwise modified being herein called
the "Repayment Agreement") to which reference is hereby made for a statement of
the rights of Bank and the duties and obligations of Borrower in relation
thereto, but neither this reference to the Repayment Agreement nor any provision
thereof shall affect or impair the absolute and unconditional obligation of
Borrower to pay the principal of and interest on this Amended Note when due.
This Amended Note amends and restates in its entirety the Amended and Restated
Revolving Credit Note dated September 28, 1998 in the principal amount of
$6,000,000.00, including any amendments or modifications thereto, and referred
to in the Repayment Agreement and does not represent evidence of new
indebtedness, or repayment of any indebtedness. The notes which formerly
evidenced the debt now evidenced by

                                       1
<PAGE>   2

this Amended Note shall remain in full force and effect only for the purpose of
evidencing any amounts due thereunder which for any reason, in fact or in law,
that do not become obligations of the Borrower under this Amended Note as
intended by the Borrower. Capitalized terms used herein and not defined shall
have the meaning given to them in the Repayment Agreement. The headings of
paragraphs of the Repayment Agreement and the titles of any and all documents
executed in conjunction therewith, including this Amended Note, are for the
convenience of reference only, and are not to be considered as limiting or
otherwise affecting any of the terms hereof or thereof.

         This Amended Note and every other obligation, indebtedness, and
liability of Borrower to Bank, whether joint or several, absolute or contingent,
due or to become due, and whether heretofore or hereafter contracted or existing
and in whatsoever manner acquired by or accruing to Bank, whether before or
after maturity and whether the same may have been or shall be participated, in
whole or in part to others, and including all amendments, extensions, and
renewals thereof (all herein called "Obligations"), are secured as set forth in
the Repayment Agreement.

         Borrower represents and warrants that it is a duly-organized and
existing corporation under the laws of the State of Michigan that the execution
and delivery hereof have been duly authorized by appropriate corporate action,
that there is no prohibition either in law, in its articles of incorporation,
by-laws, or regulations, or in any agreement to which it is a party which in any
way restricts or prevents the execution of this Amended Note and performance of
the Obligations herein in any respect, and that this Amended Note has been duly
executed and is a valid and binding Obligation of Borrower.

         Borrower shall be in default hereunder if there shall occur an Event of
Default as set forth in the Repayment Agreement. If there shall occur any Event
of Default, Bank, by notice given to Borrower (only if and to the extent such
notice is required by the Repayment Agreement), may declare the unpaid principal
of and accrued interest owing upon this Amended Note and all other Obligations
to be immediately due and payable and upon any such declaration such principal
and interest shall become and be forthwith due and payable without any further
notice, presentment, or demand of any kind, all of which are hereby expressly
waived by Borrower. Further as provided in the Repayment Agreement for specific
Events of Default, the unpaid principal and accrued interest owing upon this
Amended Note and all other Obligations shall become and be forthwith due and
payable without declaration, notice, presentment, or demand of any kind, all of
which are hereby expressly waived by Borrower.

         Wherever used in this Amended Note, the term "Bank" shall include any
holder or assignee of this Amended Note. Except for notice expressly required by
the Repayment Agreement, if any, Borrower and each endorser, guarantor, and
surety hereof waives presentment, demand for payment, protest, notice of
protest, and notice of nonpayment, and further agrees and consents that, without
notice and without affecting their liability hereon, the holder hereof at any
time or times is authorized to: (a) correct patent errors and fill blanks
herein; (b) cause or permit the signature of one or more additional makers,
co-makers, sureties, guarantors and/or endorsers to be added hereto; (c) extend
the time of payment of this Amended Note in whole or in part; (d) sell,
exchange, surrender, substitute or otherwise deal with any collateral now or
hereafter securing this Amended Note; (e) add or release any other person

                                       2
<PAGE>   3

primarily or secondarily liable on this Amended Note; and (f) modify, waive,
supplement or otherwise change the terms of any security agreement pertaining to
this Amended Note.

         Borrower understands and agrees that this Amended Note is subject to
and shall be construed according to the laws of the State of Michigan, without
regard to principles of conflict of laws. Bank's rights, remedies, and powers
that are expressly specified in this Amended Note are in addition to Bank's
rights, remedies, and powers under any other instrument or agreement or under
applicable law.

         Any deposits or sums at any time credited by or due from Bank to
Borrower and any securities or other personal property of Borrower in the
possession of Bank may at all times be held and treated as additional security
for the payment of the Obligations. After the occurrence of any Event of
Default, Bank may apply or set off such deposits or other sums against the
Obligations at any time and without further notice.

         Any waiver of Bank's rights hereunder must be in writing and signed by
Bank. A waiver on any one or more occasions shall not be construed as a bar to
or waiver of any such right or remedy on a future occasion, nor as the
establishment of a course of dealing with respect to such waiver(s) or any other
action or inaction of Bank referred to in this paragraph. Delay or failure by
Bank to exercise its powers, rights, or remedies, in whole or in part, shall not
be deemed a waiver of any such power, right, or remedy; no single or partial
exercise of any right, power, or remedy hereunder shall preclude the exercise of
any other right, power, or remedy. All agreements, representations, and
warranties made herein will survive the making of the loan evidenced by this
Amended Note and will bind and inure to the benefit of Borrower and its
successors and assigns and Bank and its successors and assigns.

         Any notice required or authorized to be given to Borrower pursuant to
the provisions of this Amended Note shall be sufficiently given when such notice
is either delivered, sent by telegram, or mailed (deposited for delivery,
postage prepaid, by U.S. mail) to Borrower either at the address set forth below
(as modified by any change therein which Borrower has supplied in writing to
Bank) or at any other address at which Bank customarily communicates with
Borrower.

         If any provision of this Amended Note, or any covenant, stipulation,
obligation, agreement, act, or action, or part thereof made, assumed, entered
into, or taken hereunder or any application thereof, is for any reason held to
be illegal or invalid, such illegality or invalidity shall not affect any other
provision or any other covenant, stipulation, obligation, agreement, act, or
action or part thereof, made, assumed, entered into, or taken, each of which
shall be construed and enforced as if such illegal or invalid portion were not
contained herein. Such illegality or invalidity of any application of any
provision hereof shall not affect any legal and valid application thereof, and
each such provision, covenant, stipulation, obligation, agreement, act, or
action, or part shall be deemed to be effective, operative, made, entered into,
or taken in the manner and to the full extent permitted by law.

         The relationship between Borrower and Bank with respect to this Amended
Note and any writing executed or delivered in connection herewith is and shall
be solely that of debtor and creditor, respectively, and Bank has no fiduciary
obligation toward Borrower with respect to any such document or the transactions
contemplated thereby.

                                       3
<PAGE>   4

         This Amended Note and any agreement, document or instrument referred to
herein or executed between Bank and Borrower on or as of the date hereof
integrate all of the terms and conditions mentioned herein or incidental hereto
and supersede all oral representations and negotiations and prior writings with
respect to the subject matter hereof.

         Borrower agrees to promptly reimburse Bank for all costs and expenses,
including attorney's fees of Bank's in-house or outside counsel incurred by Bank
in connection with any restructurings of this Amended Note or any documents
executed and delivered in connection herewith and in connection with any
collection proceedings as a result of nonpayment of this Amended Note, as and
when due and payable.

         Borrower has received consideration which is the reasonable equivalent
value of the obligations and liabilities that Borrower has incurred to Bank.
Borrower is not insolvent as defined in any applicable state or federal statute,
nor will Borrower be rendered insolvent by the execution and delivery of this
Amended Note to Bank. Borrower is not engaged or about to engage in any business
or transaction for which the assets retained by it shall be an unreasonably
small capital, taking into consideration the obligations to Bank incurred
hereunder. Borrower does not intend to, nor does it believe that it will, incur
debts beyond its ability to pay them as they mature.

         Borrower, to the extent permitted by law, waives any right to have a
jury participate in resolving any dispute, whether sounding in contract, tort,
or otherwise, between Bank and Borrower arising out of, in connection with,
related to, or incidental to the relationship established between Borrower and
Bank in connection with this Amended Note or any other agreement, instrument or
document executed or delivered in connection therewith or the transactions
related thereto.

         For value received, the undersigned (herein called "Borrower") promises

Interest on the principal balance of this Amended Note shall be payable on the

         This Amended Note is issued pursuant to a certain Repayment Agreement
executed on September 28, 1998, as amended by a First Amendment to Repayment
Agreement and Fourth Amendment to Loan Agreement of even date herewith by and
between Borrower and Bank, among others (said Repayment Agreement as it may be
from time to time amended, restated or otherwise modified being herein called
the "Repayment Agreement") to which reference is hereby made for a statement of
the rights of Bank and the duties and obligations of Borrower in relation
thereto, but neither this reference to the Repayment Agreement nor any provision
thereof shall affect or impair the absolute and unconditional obligation of
Borrower to pay the principal of and interest on this Amended Note when due.
This Amended Note amends and restates in its entirety the Amended and Restated
Term Note dated September 28, 1998 in the principal amount of $1,230,000.00,
including any amendments or modifications thereto, and referred to in the
Repayment Agreement and does not represent evidence of new indebtedness, or
repayment of any indebtedness. The notes which formerly evidenced the debt now
evidenced by this Amended Note shall remain in full force and effect only for
the purpose of evidencing any 

                                       1
<PAGE>   2

amounts due thereunder which for any reason, in fact or in law, that do not
become obligations of the Borrower under this Amended Note as intended by the
Borrower. Capitalized terms used herein and not defined shall have the meaning
given to them in the Repayment Agreement. The headings of paragraphs of the
Repayment Agreement and the titles of any and all documents executed in
conjunction therewith, including this Amended Note, are for the convenience of
reference only, and are not to be considered as limiting or otherwise affecting
any of the terms hereof or thereof.

         This Amended Note and every other obligation, indebtedness, and
liability of Borrower to Bank, whether joint or several, absolute or contingent,
due or to become due, and whether heretofore or hereafter contracted or existing
and in whatsoever manner acquired by or accruing to Bank, whether before or
after maturity and whether the same may have been or shall be participated, in
whole or in part to others, and including all amendments, extensions, and
renewals thereof (all herein called "Obligations"), are secured as set forth in
the Repayment Agreement.

         Borrower represents and warrants that it is a duly-organized and
existing corporation under the laws of the State of Michigan that the execution
and delivery hereof have been duly authorized by appropriate corporate action,
that there is no prohibition either in law, in its articles of incorporation,
by-laws, or regulations, or in any agreement to which it is a party which in any
way restricts or prevents the execution of this Amended Note and performance of
the Obligations herein in any respect, and that this Amended Note has been duly
executed and is a valid and binding Obligation of Borrower.

         Borrower shall be in default hereunder if there shall occur an Event of
Default as set forth in the Repayment Agreement. If there shall occur any Event
of Default, Bank, by notice given to Borrower (only if and to the extent such
notice is required by the Repayment Agreement), may declare the unpaid principal
of and accrued interest owing upon this Amended Note and all other Obligations
to be immediately due and payable and upon any such declaration such principal
and interest shall become and be forthwith due and payable without any further
notice, presentment, or demand of any kind, all of which are hereby expressly
waived by Borrower. Further as provided in the Repayment Agreement for specific
Events of Default, the unpaid principal and accrued interest owing upon this
Amended Note and all other Obligations shall become and be forthwith due and
payable without declaration, notice, presentment, or demand of any kind, all of
which are hereby expressly waived by Borrower.

         Wherever used in this Amended Note, the term "Bank" shall include any
holder or assignee of this Amended Note. Except for notice expressly required by
the Repayment Agreement, if any, Borrower and each endorser, guarantor, and
surety hereof waives presentment, demand for payment, protest, notice of
protest, and notice of nonpayment, and further agrees and consents that, without
notice and without affecting their liability hereon, the holder hereof at any
time or times is authorized to: (a) correct patent errors and fill blanks
herein; (b) cause or permit the signature of one or more additional makers,
co-makers, sureties, guarantors and/or endorsers to be added hereto; (c) extend
the time of payment of this Amended Note in whole or in part; (d) sell,
exchange, surrender, substitute or otherwise deal with any collateral now or
hereafter securing this Amended Note; (e) add or release any other person
primarily or secondarily liable on this Amended Note; and (f) modify, waive,
supplement or otherwise change the terms of any security agreement pertaining to
this Amended Note.

                                       2

         Borrower understands and agrees that this Amended Note is subject to
and shall be construed according to the laws of the State of Michigan, without
regard to principles of conflict of laws. Bank's rights, remedies, and powers
that are expressly specified in this Amended Note are in addition to Bank's
rights, remedies, and powers under any other instrument or agreement or under
applicable law.

         Any deposits or sums at any time credited by or due from Bank to
Borrower and any securities or other personal property of Borrower in the
possession of Bank may at all times be held and treated as additional security
for the payment of the Obligations. After the occurrence of any Event of
Default, Bank may apply or set off such deposits or other sums against the
Obligations at any time and without further notice.

         Any waiver of Bank's rights hereunder must be in writing and signed by
Bank. A waiver on any one or more occasions shall not be construed as a bar to
or waiver of any such right or remedy on a future occasion, nor as the
establishment of a course of dealing with respect to such waiver(s) or any other
action or inaction of Bank referred to in this paragraph. Delay or failure by
Bank to exercise its powers, rights, or remedies, in whole or in part, shall not
be deemed a waiver of any such power, right, or remedy; no single or partial
exercise of any right, power, or remedy hereunder shall preclude the exercise of
any other right, power, or remedy. All agreements, representations, and
warranties made herein will survive the making of the loan evidenced by this
Amended Note and will bind and inure to the benefit of Borrower and its
successors and assigns and Bank and its successors and assigns.

         Any notice required or authorized to be given to Borrower pursuant to
the provisions of this Amended Note shall be sufficiently given when such notice
is either delivered, sent by telegram, or mailed (deposited for delivery,
postage prepaid, by U.S. mail) to Borrower either at the address set forth below
(as modified by any change therein which Borrower has supplied in writing to
Bank) or at any other address at which Bank customarily communicates with
Borrower.

         If any provision of this Amended Note, or any covenant, stipulation,
obligation, agreement, act, or action, or part thereof made, assumed, entered
into, or taken hereunder or any application thereof, is for any reason held to
be illegal or invalid, such illegality or invalidity shall not affect any other
provision or any other covenant, stipulation, obligation, agreement, act, or
action or part thereof, made, assumed, entered into, or taken, each of which
shall be construed and enforced as if such illegal or invalid portion were not
contained herein. Such illegality or invalidity of any application of any
provision hereof shall not affect any legal and valid application thereof, and
each such provision, covenant, stipulation, obligation, agreement, act, or
action, or part shall be deemed to be effective, operative, made, entered into,
or taken in the manner and to the full extent permitted by law.

         The relationship between Borrower and Bank with respect to this Amended
Note and any writing executed or delivered in connection herewith is and shall
be solely that of debtor and creditor, respectively, and Bank has no fiduciary
obligation toward Borrower with respect to any such document or the transactions
contemplated thereby.

                                       3
<PAGE>   4
         This Amended Note and any agreement, document or instrument referred to
herein or executed between Bank and Borrower on or as of the date hereof
integrate all of the terms and conditions mentioned herein or incidental hereto
and supersede all oral representations and negotiations and prior writings with
respect to the subject matter hereof.

         Borrower agrees to promptly reimburse Bank for all costs and expenses,
including attorney's fees of Bank's in-house or outside counsel incurred by Bank
in connection with any restructurings of this Amended Note or any documents
executed and delivered in connection herewith and in connection with any
collection proceedings as a result of nonpayment of this Amended Note, as and
when due and payable.

         Borrower has received consideration which is the reasonable equivalent
value of the obligations and liabilities that Borrower has incurred to Bank.
Borrower is not insolvent as defined in any applicable state or federal statute,
nor will Borrower be rendered insolvent by the execution and delivery of this
Amended Note to Bank. Borrower is not engaged or about to engage in any business
or transaction for which the assets retained by it shall be an unreasonably
small capital, taking into consideration the obligations to Bank incurred
hereunder. Borrower does not intend to, nor does it believe that it will, incur
debts beyond its ability to pay them as they mature.

         Borrower, to the extent permitted by law, waives any right to have a
jury participate in resolving any dispute, whether sounding in contract, tort,
or otherwise, between Bank and Borrower arising out of, in connection with,
related to, or incidental to the relationship established between Borrower and
Bank in connection with this Amended Note or any other agreement, instrument or
document executed or delivered in connection therewith or the transactions
related thereto.

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR UNDER ANY OTHER SECURITIES LAWS. IT MAY NOT BE SOLD
OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO
THIS NOTE UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE PAYOR THAT SUCH REGISTRATION IS NOT REQUIRED.

                           CONVERTIBLE PROMISSORY NOTE

$______________                                              December 1, 1998
                                                             Ann Arbor, Michigan

         FOR VALUE RECEIVED, the undersigned, Nematron Corporation, a Michigan
corporation (the "Payor"), hereby promises to pay to _________________, an
individual [corporation] (the "Payee"), at ____________________________________,
or at such other place or places as the Payee may designate from time to time in
writing to the Payor, in lawful money of the United States of America and in
immediately available funds, the aggregate principal sum of
_____________________________ ($_____________), and to pay interest on the
outstanding principal balance at the rate of seven percent (7%) per annum, and
after maturity or the occurrence of an event of default hereunder, at the rate
of nine percent (9%) per annum. The payment of the principal and all accrued and
unpaid interest thereon shall be due and payable on March 31, 1999 (the
"Maturity Date"). Interest shall be charged on the basis of a year of 365 days.

         This Note may be prepaid at any time and from time to time, in whole
but not in part, without penalty or premium, upon five (5) days prior written
notice from the Payor to the Payee, unless, prior to such repayment, Payee
provides notice to Payor of its intent to exercise its conversion rights
provided in the third paragraph of this note (Payee's notice of intent to
exercise its conversion rights shall be effective notwithstanding Payor's notice
of intent to repay). This Note shall be payable or prepayable, at the sole
discretion of the Payor, in cash or the Payor's common stock ("Common Stock").
For the purpose of payment or prepayment of this Note, Common Stock shall be
valued at $.25 per share (the "Payment and Conversion Price").

         Subject to the terms and conditions set forth herein, the principal and
interest due and payable under this Note may be converted by Payee, in whole or
in part, into Common Stock upon fifteen (15) days prior written notice from the
Payee to the Payor and prior to the earlier of (i) the Maturity Date or (ii) the
prepayment in whole of this Note. The number of shares of Common Stock issuable
upon such conversion shall be the principal and interest then due and payable
under this Note divided by the Payment and Conversion Price, rounded down to the
nearest whole share. No fractional shares shall be issued upon conversion of
this Note. In the event any merger, reorganization, consolidation,
recapitalization, stock dividend or other change in corporate structure
affecting Common Stock occurs after the date hereof and prior to the Maturity
Date, an equivalent adjustment shall be made in the aggregate number of shares
which may be delivered upon conversion hereunder. Notwithstanding the foregoing
provisions of this paragraph, the Payor shall not be required to issue more than
_________ shares of Common Stock to the Payee pursuant to this paragraph unless
the issuance of any additional shares (if aggregated with all other issuances
and potential issuances of Common Stock pursuant to this Note and the other
notes issued by the Payor on the date hereof and upon exercise of the Options
granted pursuant to this Note and the other notes issued by the Payor on the
date hereof) has been approved by the shareholders of the Payor to the extent
required by applicable law, Payor's organizational documents or the rules of the
Nasdaq Stock Market (the "Required Approval"). Any portion of the principal or
interest under this Note which Payee attempts to convert into Common Stock but
which cannot be converted due to the limitation in the immediately preceding
sentence shall remain outstanding under this Note until otherwise paid, prepaid
or converted.

                                       2
<PAGE>   3

         The Payor agrees to file one registration statement with the Securities
and Exchange Commission to register the shares of its Common Stock issued upon
payment or conversion of this Note (if any), including the shares issued
pursuant to the Option granted in the tenth paragraph of this Note, following
the issuance of such shares, in accordance with the terms and subject to the
conditions of a registration rights agreement to be negotiated and entered into
by the Payor and the Payee in a form reasonably satisfactory to both parties.
Payor's failure to comply with the foregoing obligation to register such shares
or the obligations in such registration rights agreement shall constitute an
event of default under this Note.


         THE PAYOR AND THE PAYEE, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY
TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHT EITHER OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR
ARISING OUT OF THIS NOTE, OR ANY COURSE OF CONDUCT, DEALING, STATEMENT (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF EITHER OF THEM. NEITHER THE PAYOR NOR THE PAYEE
SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY ACTION IN WHICH A
JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE
OR HAS NOT BEEN WAIVED.

         The undersigned Payor hereby waives demand, presentment, protest,
dishonor and notice of dishonor in connection with this Note.

         In the event any action is taken to collect or enforce the indebtedness
evidenced by this Note or any part thereof, the undersigned agrees to pay, in
addition to the principal and interest due and payable hereon, all reasonable
costs of collecting this Note, including reasonable attorneys' fees and
expenses.

         Acceptance by the Payee of any payment in an amount less than the
amount then due and owing shall be deemed an acceptance on account only, and the
failure to pay the entire amount then due and owing shall cause the Payor to
remain in default.

         This Note and the Option granted below may not be sold, assigned or
otherwise transferred without the prior written consent of Payor, which consent
shall not be unreasonably withheld. In all events, a transfer to Payee's
revocable living trust shall be allowed after written notice provided to the
Payor.

         This Note is made under, and shall be governed by and construed in
accordance with, the laws of the State of Michigan as to notes made and
performed entirely within such State and without giving effect to choice of law
principles of such State.

         Payor hereby grants to Payee a fully paid option to purchase a
convertible promissory note of the Payor (the "Option Note") with a principal
amount of $____________ (the "Option Principal Amount"), having substantially
the same terms as this Note (but excluding the terms relating to this option)
and convertible into a total of _____________ shares (the "Option Shares") of
Common Stock at $.25 per share (the "Option") upon the following terms and
conditions: (1) The Option may be exercised in whole, but not in part, at any
time after the date hereof until 5:00 p.m. Eastern Standard Time on January 31,
1999 (the "Expiration Time"); (2) The Option may be exercised only upon written
notice of such exercise (stating the name and address, amount of subscription
and social security number (or EIN) of such investor) accompanied by payment in
full by a wire transfer, in immediately available funds to a bank account
designated by the Payor, of an amount equal to the Option Principal Amount; (3)
If the Option is exercised, Payee shall be deemed to have represented that the
Option Note and the Option Shares have been purchased for Payee's own account,
or as the case may be, for the accounts of the Payee's designee as provided
herein, and not for the purpose of resale or distribution; (4) If the Option is
exercised, Payee shall be deemed to have acknowledged that the Option Note and
the Option Shares have not been 

                                       3

<PAGE>   4

registered under the Securities Act of 1933, as amended (the "Securities Act"),
or under any other securities laws and may not be sold or offered for sale in
the absence of an effective registration statement as to the Option Note and the
Option Shares under the Securities Act or an opinion of counsel reasonably
satisfactory to the Payor that such registration is not required. This Note was
entered into as a last resort and in good faith. Payor will not solicit from
third parties offers or solicitations of offers for purchase of shares until the
Required Approvals are received or rejected; provided that Payor shall be
permitted to solicit offers to purchase additional Option Notes as long as such
Option Notes when sold do not have an aggregate principal amount, together with
the Option Notes issued upon exercise of the Options granted pursuant to this
Note and the other notes issued by Payor on the date hereof, exceeding $3
million; and further provided, that Payor's Board of Directors, on behalf of
Payor, may furnish information and may participate in discussions and
negotiations through its representatives with persons who have sought the same
if the failure to provide such information or participate in such negotiations
or discussions would cause the directors to breach their fiduciary duties to
Payor's shareholders under applicable law.

         Notwithstanding any provision in this Note to the contrary, Payor shall
not be required to issue any shares of Common Stock in excess of the number of
shares referenced in the third paragraph of this Note if any Required Approval
has not been received or if such issuance would constitute a violation of any
applicable Federal or state securities law or any other law or regulation. If
shareholder approval is required, Payor agrees to seek, as soon a practicable
following execution of this Promissory Note, the approval of its shareholders of
the issuance of any such shares to the extent required by applicable law,
Payor's organizational documents or the rules of the Nasdaq Stock Market.

affecting Common Stock occurs after the date hereof and prior to the Maturity
Date, an equivalent adjustment shall be made in the aggregate number of shares
which may be delivered upon conversion hereunder. Notwithstanding the foregoing
provisions of this paragraph, the Payor shall not be required to issue more than
_________ shares of Common Stock to the Payee pursuant to this paragraph unless
the issuance of any additional shares (if aggregated with all other issuances
and potential issuances of Common Stock pursuant to this Note and the other
notes issued by the Payor on the date hereof and upon exercise of the Options
granted pursuant to the other notes issued by the Payor on the date hereof) has
been approved by the shareholders of the Payor to the extent required by
applicable law, Payor's organizational documents or the rules of the Nasdaq
Stock Market (the "Required Approval"). Any portion of the principal or interest
under this Note which Payee attempts to convert into Common Stock but which
cannot be converted due to the limitation in the immediately preceding sentence
shall remain outstanding under this Note until otherwise paid, prepaid or
converted.

         The Payor agrees to file one registration statement with the Securities
and Exchange Commission to register the shares of its Common Stock issued upon
payment or conversion of this Note (if any following the issuance of such
shares, in accordance with the terms and subject to the conditions of a
registration rights agreement to be negotiated and entered into by the Payor and
the Payee in a form reasonably satisfactory to both parties. Payor's failure to
comply with the foregoing obligation to register such shares or the obligations
in such registration rights agreement shall constitute an event of default under
this Note.


         THE PAYOR AND THE PAYEE, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY
TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHT EITHER OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR
ARISING OUT OF THIS NOTE, OR ANY COURSE OF CONDUCT, DEALING, STATEMENT (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF EITHER OF THEM. NEITHER THE PAYOR NOR THE PAYEE
SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY ACTION IN WHICH A
JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE
OR HAS NOT BEEN WAIVED.

         The undersigned Payor hereby waives demand, presentment, protest,
dishonor and notice of dishonor in connection with this Note.

         In the event any action is taken to collect or enforce the indebtedness
evidenced by this Note or any part thereof, the undersigned agrees to pay, in
addition to the principal and interest due and payable hereon, all reasonable
costs of collecting this Note, including reasonable attorneys' fees and
expenses.

         Acceptance by the Payee of any payment in an amount less than the
amount then due and owing shall be deemed an acceptance on account only, and the
failure to pay the entire amount then due and owing shall cause the Payor to
remain in default.

         This Note may not be sold, assigned or otherwise transferred without
the prior written consent of Payor, which consent shall not be unreasonably
withheld. In all events, a transfer to Payee's revocable living trust shall be
allowed after written notice provided to the Payor.

         This Note is made under, and shall be governed by and construed in
accordance with, the laws of the State of Michigan as to notes made and
performed entirely within such State and without giving effect to choice of law
principles of such State.

         This Note was entered into as a last resort and in good faith. Payor
will not solicit from third parties offers or solicitations of offers for
purchase of shares until the Required Approvals are received or rejected;
provided that Payor shall be permitted to solicit offers to purchase additional
Option Notes as long as such Option Notes when sold do not have an aggregate
principal amount, together with the other notes issued by Payor on the date
hereof, exceeding $3 million; and further provided, that Payor's Board of
Directors, on behalf of Payor, may furnish information and may participate in
discussions and negotiations through its representatives with persons who have
sought the same if the failure to provide such information or participate in
such negotiations or discussions would cause the directors to breach their
fiduciary duties to Payor's shareholders under applicable law.

         Notwithstanding any provision in this Note to the contrary, Payor shall
not be required to issue any shares of Common Stock in excess of the number of
shares referenced in the third paragraph of this Note if any Required Approval
has not been received or if such issuance would constitute a violation of any
applicable Federal or state securities law or any other law or regulation. If
shareholder approval is required, Payor agrees to seek, as soon a practicable
following execution of this Promissory Note, the approval of its shareholders of
the issuance of any such shares to the extent required by applicable law,
Payor's organizational documents or the rules of the Nasdaq Stock Market.
