                                     PART I

ITEM 1.           DESCRIPTION OF BUSINESS

GENERAL

         ISS was founded in 1984 to develop and market products using video
image processing technology for use in advanced traffic management systems and
traffic data collection. Video image processing, also known as machine vision or
artificial vision, is a technology that analyzes video images through computer
programs and special purpose hardware. By using video cameras and computers to
emulate the function of the human eye, machine vision has been used in a variety
of industrial applications. ISS has combined its proprietary machine vision
technology, consisting of complex algorithms, software, and special purpose
hardware with commercially available computer hardware and video cameras, to
create a system that collects, processes, and analyzes video images.

         The Company's first product, the Autoscope(R) Wide Area Video Vehicle
Detection System, converts video images of a traffic scene into digitized
traffic data that may be transmitted to local or remote locations for real-time
traffic management or stored for later analysis. The Autoscope system is
modular, flexible, and expandable and has a variety of current and potential
applications in intersection control, freeway traffic management, and traffic
data collection. Automated vehicle detection for traffic management has
traditionally been performed with inductive wire loops buried in the pavement.
The Autoscope system is easier to install and maintain than these embedded loop

                                       2

detectors; is non-destructive to road surfaces; and is capable of wide-area
vehicle detection with a single camera, thus enabling one camera to do the work
of many loops. The Company believes that the Autoscope system is superior to
loop detectors or most other commercially available vehicle detection systems in
its current range of applications and its ability to support new applications
for advanced technology solutions to traffic management problems.

         In 1987, the University of Minnesota, utilizing the technology
underlying the Autoscope system, demonstrated the first working traffic
application of image processing technology. The U.S. patent for certain aspects
of the technology underlying the Autoscope system was issued in 1989 to the
University of Minnesota. The Company has an exclusive worldwide license from the
University of Minnesota for that technology and the patent and pays royalties to
the University of Minnesota in exchange for such license. The Company has
sublicensed the exclusive right to manufacture and market the Autoscope system
in North America and the Caribbean to Econolite Control Products, Inc.
(Econolite) of Anaheim, California and receives royalties from Econolite on
sales of the Autoscope system in those territories. Econolite also manufactures
the Autoscope system on a non-exclusive basis for direct sales by the Company
outside of North America and the Caribbean. In 1997, ISS and Econolite jointly
entered into a Production Agreement with Cohu, Inc., Electronic Division (Cohu),
wherein ISS and Econolite each granted to Cohu a non-exclusive right to
manufacture the Autoscope Solo product solely for sale to ISS and Econolite.

         The Autoscope system was first marketed and sold commercially in 1991.
In 1993, the Company began to market the Autoscope system outside of North
America through distributor arrangements, and the Company intends to continue to
increase its marketing efforts in foreign countries. The Company currently has
twenty-one distributors covering countries primarily in Europe, Asia, and South
America.

 TECHNOLOGY

         The machine vision industry utilizes technology that converts real
world "scenic" information into digital electronic signals for processing by
computer. Machine vision has a number of industrial applications. For example,
machine vision technology is used for quality control in manufacturing
processes. An image of a manufactured product can be fed by video into a
computer and analyzed to determine if that finished product satisfies production
standards that have been programmed into the computer. The defense industry has
used machine vision in a number of applications. For example, "smart" bombs use
video imaging technology to identify targets through the use of special optic
sensors that feed scenic information into sophisticated computer programs that
process the scenic information into target location coordinates.

         Through the use of its sophisticated proprietary technology, the
Company has been able to apply machine vision technology to traffic management
problems. The Company's technology was initially developed by Dr. Panos
Michalopoulos, Chairman of the Board and Chief Scientific Advisor of ISS and a
Professor at the University of Minnesota, and was further developed at the
University of Minnesota from 1985 to 1991 with involvement by Dr. Michalopoulos.
The technology uses standard video and computer equipment, combined with
proprietary technology, including complex detection algorithms, computer
software, special purpose hardware, and a Microsoft Windows(R)-based graphical
user interface that enables standard video cameras to work with the Autoscope
system.



                                       3

THE AUTOSCOPE SYSTEM

         The Autoscope 2004 system generally consists of one to four video
cameras, a flexible modular microprocessor with specialized software and
circuitry, and a supervisor computer with a video monitor, keyboard, and mouse.
The Autoscope Solo system (Solo) incorporates the microprocessor and circuitry
into a single video camera. The Autoscope microprocessor in both the 2004 and
Solo systems accepts scenic input from the video cameras and, through a series
of complex algorithms and computer software, converts the scenic data into
digitized data. This data can then be used for traffic control, research,
management, and planning purposes. Most brands of commercially available
personal computers with standard configurations can be used as the supervisor
computer in the system.

         The Autoscope system permits a user to draw detection zones on a video
screen displaying the traffic scene and derive traffic data from the portion of
the image specified by the detection zones displayed on the screen. The system
analyzes virtual detection zones that appear only on the video screen, not on
the roadway. Each detection zone represents an area in the field of view of the
camera that the system user wishes to analyze for determining the presence of
vehicles or extracting other pertinent traffic data. Over 100 detection zones
can be programmed into multi-camera systems. The system user determines the
detection zones by drawing them on a video monitor with a mouse. Different types
of detection zones can be selected and may be placed anywhere in any orientation
within the field of view of the cameras using the system's unique interactive
graphics. The detection zones can be changed simply by using the mouse to
resize, reshape, or relocate the detection zones on the video monitor. Once a
new detection configuration has been created, the supervisor computer system can
display the detection zones on its own video monitor, together with the live
video image, to monitor the system in operation. When a vehicle is under the
detection zone, the detection zone changes in color or intensity, thereby
providing visual verification of correct system operation. Measured traffic data
may be displayed on the video monitor of the supervisor computer in numeric
format. The traffic data may be transmitted to another host computer via modem
and dial-up telephone lines, private cable, fiber optic network, direct cable
connection, or various other wireless communications equipment. Vehicle
detection output can also be routed to intersection signal controllers. A
detection signal is generated each time a vehicle crosses one of the virtual
detection zones, thus enabling the system to accumulate measured traffic data in
user-selected categories, such as volume, average speed, time occupancy (percent
of time the detection zone is occupied), headways (time interval between
vehicles), flow rate (vehicles per hour per lane), and vehicle length.
Information from the system can be processed in real-time or stored for later
analysis.

         The Autoscope system is modular, flexible, and expandable. The
Autoscope supervisor computer and video monitor may be disconnected once the
detection zone configuration has been transferred to the microprocessor. The
system can then operate independently, providing detection zone outputs and
storing traffic data in the microprocessor's internal memory. The same portable
supervisor computer and video monitor may be used with multiple Autoscope
systems. New detection zone configurations can be saved to diskette, and
previously saved detection zone configurations can be retrieved from diskette
for downloading into each system. The same Autoscope microprocessor can be used
with multiple cameras, each with its own detection zone configuration.



                                       4
<PAGE>

         The Company introduced its new product, Autoscope Solo, in October
1998. The Solo, which integrates the video image processor camera and
peripherals, was developed over the last two years and has now been deployed in
two large projects in Minneapolis and St. Paul, Minnesota.

CURRENT APPLICATIONS AND INSTALLATIONS

         The current Autoscope system may be used in a number of applications,
primarily for intersections, freeways, tunnels, and traffic count stations. In
addition, the Company has identified additional potential traffic and
non-traffic related applications for the system that it intends to pursue.

INTERSECTION APPLICATIONS. The Autoscope system can be installed at an
intersection to provide traffic detection information as required by an
intersection signal controller. An intersection signal controller is essentially
a device that contains a set of sophisticated computer programs, separate from
the vehicle detection system, that uses the traffic detection information to
control the green, yellow, and red lights for each of the turning or through
lanes to provide for safe and efficient movement of vehicles through the
intersection. More sophisticated intersection signal controllers use detection
information to maximize the efficient flow of traffic through one or more
intersections. The extent to which a signal controller is successful is
dependent not only on the level of sophistication of the controller but also on
the quality and reliability of the detection system and the type of traffic data
provided.

         The Autoscope system can be programmed to provide data with respect to
vehicle presence, traffic volume, time occupancy (percent of time the detection
zone is occupied), vehicle speed, turning movements, queue lengths, stopped
vehicles, vehicle direction, and vehicle length. This information is then routed
to the intersection signal controller to control the flow of traffic at the
intersection or provide alarms at centralized traffic control centers. For
example, the Autoscope system can determine that a queue has developed at a
stoplight and route that information to the intersection controller so that the
signal times can be adjusted appropriately or a left turn signal phase can be
engaged if a line develops at the left turn lane. In addition, selected
detection zones in the Autoscope system can be programmed so that they only
detect cars moving in one direction. This capability can be used to prevent
undesired detections, such as a left turning vehicle that has turned too sharply
and is momentarily driving in the wrong lane. This capability can also be used
to detect cars going the wrong way on a one way street or the wrong way on a
freeway exit-ramp. A majority of all commercially installed Autoscope systems
are currently being used for intersection control applications.

FREEWAY APPLICATIONS. For freeway applications, Autoscope provides information
for traffic management analysis, ramp control, incident detection, and automated
surveillance. Typical traffic information provided by the system includes
traffic volumes, time occupancy, vehicle speeds and vehicle counts of three
different vehicle classes based on length. The system is also used to signal an
alarm if it detects stopped vehicles or the sudden onset of congestion in a
detection zone indicating a traffic incident on the highway. Using a video
camera next to a freeway on-ramp, the Autoscope system detects traffic movement
on a freeway on-ramp or in the 



                                       5
<PAGE>

merging area on the freeway, and the resulting data is used to prevent a queue
from developing on a side street, to control on-ramp traffic signals, or to
determine the capacity of a merge area for planning and control purposes.

TRAFFIC INFORMATION GATHERING AND ANALYSIS. The Autoscope system is also used
for basic traffic information gathering and analysis on intersections, freeways,
and other roadways. Traffic planners use the traffic data collected by the
Autoscope system to design roadway changes, define signal timing plans, approve
commercial development plans, and define the environmental impact of traffic
congestion. The Autoscope system has been deployed in temporary or
semi-permanent configurations as a portable detection system during road
repairs, construction, or resurfacing and for special studies, such as traffic
data collection by a planning department, a traffic consultant or a university.
The Autoscope system captures vast amounts of traffic data in its own memory or
on a hard disk of the supervisor computer for later off-line graphing and
analysis. Further flexibility is gained with the ability to videotape a section
of roadway with a portable video camera and measure the traffic data off-line
with the Autoscope processor.

POTENTIAL PRODUCT APPLICATIONS AND ENHANCEMENTS. The Company is engaged in a
continuous effort to increase the number of applications and develop
enhancements for the Autoscope system. Enhancements to the system are often a
result of responses to needs identified by customers in the field. The Company
has been involved in a number of consulting arrangements in which the Company
has been engaged to manage the deployment of custom applications of the
Autoscope system.

         While the Company believes that it will be able to develop and
commercialize these product enhancements and applications, there can be no
assurance that it will be able to do so or that offering such enhancements or
applications will provide the Company any unique competitive advantage over
existing or developed technology.

RESEARCH AND DEVELOPMENT

         The Company is engaged in continued research and development in order
to lower manufacturing unit costs, develop less expensive system configurations,
and improve product quality. The Company's research and development activities
also are focused on broadening the applications of the Company's system and
developing product enhancements. New applications and product enhancements are
often a result of research and development in response to needs identified by
customers in the field.

         The size of the Company's research and development staff varies in
numbers depending on the allocation of engineering resources to outside projects
and product support. Generally eleven individuals, of whom four hold advanced
degrees, are presently involved in research and development. The Company's
research and development expenditures totaled approximately $203,000 in 1998 and
$643,000 in 1997. In addition, the Company capitalized software development
costs during the application development stage for the Solo product totaling
$825,000 in 1998 and $75,000 in 1997. The combination of capitalized software
development costs and research and development costs was $1,028,000 in 1998 and
$718,000 in 1997. The 



                                       6
<PAGE>

Company expects its research and development costs in 1999 to be comparable to
the combined capitalized software development and research and development costs
incurred in 1998.

MARKETS

         Urban traffic congestion is a major global problem. Consequently, in
the United States and in many developed countries throughout the world, there is
a growing demand for traffic management and control technology. In the U.S.
local and national government agencies continuously seek new solutions to
traffic congestion. Traffic planners can build new roads or develop mass
transit. However, both of these options are expensive, time consuming, and in
many situations not feasible. In this era of governmental budgetary constraints,
traffic planners are increasingly seeking solutions that will maximize the
efficiency and utilization of the existing roadways.

         The costs due to congestion, including wasted fuel, increased
accidents, and time lost, are substantial. In a report to Congress, the U.S.
Secretary of Transportation estimated that lost productivity due to urban
traffic congestion for the twenty-five largest U.S. metropolitan areas is
approximately $34 billion per year and approximately $100 billion per year for
the entire country. In an effort to reduce these costs, the U.S. Congress, in
1991, enacted the Intermodal Surface Transportation Efficiency Act (ISTEA), the
purpose of which is to develop economically efficient and environmentally sound
solutions to transportation system problems in the U.S. As part of ISTEA
Congress endorsed a national transportation initiative known as Intelligent
Transportation Systems (ITS) and appropriated substantial funding for ITS
projects. Under ISTEA the U.S. Department of Transportation must report to
Congress periodically regarding the progress of ITS projects.

         ITS represents a new and growing area of interest within the
transportation industry, dedicated to the application of advanced technology to
meet the increased demands on the nation's transportation systems. One central
principle of the ITS program is that solutions to transportation problems in the
U.S. should focus on more efficient use of the current roads and systems, rather
than merely increasing the quantity of roads and systems. ITS encourages
technological developments that will improve highway safety, system operating
efficiency, environmental quality, or energy utilization in transportation
through improved interactions between roads, vehicles, and their drivers. ITS is
an interdisciplinary initiative composed of a number of technologies, including
those developed and used in the defense industry, information processing,
communications, control, and electronics. With funding and oversight from the
U.S. Department of Transportation, the Federal Highway Administration, and the
state departments of transportation, the ITS program seeks to develop and
implement a variety of transportation user services.

         On June 9, 1998, the Transportation Equity Act for the 21st Century
(TEA-21) was signed into law by the President of the United States. This law
authorizes $198 billion in spending for highways, highway safety, transit and
other surface transportation programs over the next five years. Over $10 billion
is earmarked for mitigation of congestion and air quality improvement, to
develop and deploy advanced intelligent transportation system technologies and
for transportation research and technology deployment. TEA-21 will provide
transportation 



                                       7
<PAGE>

managers with increased funding over the next five years to enable more
deployment of machine vision technology.

         The Company believes that implementation of advanced traffic management
schemes envisioned by ITS requires collection of real-time traffic conditions
including traffic volume, roadway occupancy, traffic speed, stopped vehicles,
vehicle direction, vehicle length, and traffic incidents. Loop detectors are
generally too expensive to install and maintain in the large quantities required
for implementing some of the more aggressive ITS programs.

         While the Company is optimistic that its Autoscope machine vision
technology will be selected for deployment in the United States with increasing
frequency, there can be no assurance that traffic managers responsible for
selecting Intelligent Transportation Systems will choose machine vision
technology over embedded loop detectors, pressure plates, radar, microwave or
other competing technologies or will choose the Autoscope system over competing
machine vision products.

         The Company is aware that other countries are initiating or
contemplating initiating programs similar to ITS. For example, the European
Community has a program called ERTICO, which is attempting to manage traffic
with advanced technology. The Company believes that as market acceptance
increases in such countries, the utilization of the Autoscope system for freeway
applications in such programs may increase. To date the Company has generated
revenues from involvement in an ITS-type program in South Korea.

CUSTOMERS

         The customers for Autoscope are primarily federal, state, city, and
county departments of transportation; road commissions; and port, turnpike,
tunnel, and other transportation authorities. The decision makers within these
government entities are typically traffic planners and government engineers, who
in turn often rely on consulting firms that perform planning and feasibility
studies for those entities. Most Autoscope systems deployed as part of an ITS
program are ordered as components of major construction contracts, under
subcontracts to system integrators or other suppliers of systems and services.
Otherwise, state and local government agencies often install and maintain their
own equipment. In order to increase sales of the Autoscope system, the Company
must continue to increase product and technology awareness within these customer
groups.

BACKLOG

         The Company's backlog of unfulfilled firm orders from distributors was
approximately $288,000 as of December 31, 1998 and was not material as of
December 31, 1997. Terms of agreements between distributors of the Company's
products and government contractors and other customers generally provide for
cancellation or rescheduling of delivery. Accordingly, the Company's backlog at
a particular date may not be indicative of its future revenue.

COMPETITION

         Competition in the area of advanced traffic management and surveillance
is growing, due in part to the increased federal funding of advanced
technologies under the ITS program. Some of the companies that may compete with
the Company in the business of developing and implementing traffic control
systems include companies that have substantially more financial, technological,
marketing, personnel, and research and development resources than the Company.
The Company's products will compete not only with conventional methods of
vehicle detection and traffic control, such as embedded loop detectors, but also
with new technologies that may be applied to problems of urban traffic
congestion. New technologies or applications in traffic control systems may
provide the Company's customers with alternatives to the Autoscope system.
Various technologies have been used as traffic sensing devices in the past and
will continue to be developed for application to traffic management. These
technologies include embedded loop detectors, pressure plates, pneumatic tubes,
radars, lasers, magnetometers, acoustics, and microwaves. The Company estimates
that over 95% of the detector systems currently in use in the U.S. are embedded
loop detectors. Embedded loop detectors are relatively easy to manufacture and
are currently manufactured by numerous companies throughout the world.

         The Company is aware of several companies that are developing traffic
management devices using machine vision technology or other advanced technology.
Among the companies that are expected to provide direct competition to the
Company's Autoscope system in the use of machine vision technology in traffic
management are Traficon N.V. (Traficon), Peek business unit of Thermo Power
Corp. (Peek), Nestor, Inc., and Odetics, Inc., (Odetics). To the Company's
knowledge, Traficon, Odetics, and Peek have working installations of their
machine vision systems in the U.S. and other parts of the world. However, these
companies do not have as many installations as ISS. To the Company's knowledge,
machine vision systems are also being developed by Nestor, Inc. The Company is
aware that these and other companies will continue to develop technologies for
use in traffic management and surveillance. One or more of these technologies
could in the future provide increased competition for the Autoscope system.
Nevertheless, the Company believes that its products have undergone more
extensive field-testing and are at a more advanced stage of development than any
of its competitors' products.

MARKETING AND MANUFACTURING

         Marketing and manufacturing of the Autoscope system in North America
and the Caribbean (the Econolite Territory) has been performed by Econolite
Control Products, Inc. of Anaheim, California pursuant to a Manufacturing,
Distributing and Technology License Agreement (the Econolite Agreement).
Pursuant to that agreement, ISS has appointed Econolite as its licensee to make,
have made, use, license, distribute and sell the Autoscope system and related
technology in the Econolite Territory. Econolite has agreed to use its best
efforts to promote the sale of the Autoscope system and not to distribute
products that compete with the Autoscope system. Econolite pays ISS a royalty on
all revenue derived by Econolite from sales of the Autoscope system. Econolite
has over 64 years of experience in the traditional traffic intersection control
industry.



                                       9
<PAGE>

         In January 1998, Econolite was certified as to ISO 9002 standards in
its manufacture of machine vision products for the transportation management
industry.

         The Company also obtained Conformite Europeenne (CE) Mark approval in
1998 for its Autoscope technology. The CE Mark is a worldwide standard for
safety and quality assurance.

         ISS may terminate the Econolite Agreement if a minimum annual sales
level is not met. The initial term of the Econolite Agreement is 15 years,
ending in 2007, automatically renewable thereafter for additional one-year
periods unless terminated by either party on 60 days notice prior to the end of
the initial term or any extension term.

         The Econolite Agreement grants a license to Econolite that encompasses
any knowledge, information, know-how, software or devices relating to vehicle
detection, whether patentable or not, that is licensed to ISS pursuant to the
License Agreement with the University of Minnesota described below under
"Patents and Proprietary Rights," and any knowledge, information, know-how,
software or devices relating to vehicle detection owned or licensable by ISS.
Econolite has a first negotiation right for extension of the license granted in
the Econolite Agreement to include rights in countries outside the Econolite
Territory. Currently, Econolite has agreed to manufacture, on a non-exclusive
basis, the Autoscope systems sold outside the Econolite Territory.

         In 1997, ISS and Econolite jointly entered into a Production Agreement
with Cohu, Inc., Electronic Division (Cohu), wherein ISS and Econolite each
granted to Cohu a non-exclusive, non-transferable, non-assignable, royalty-free
right and license to use such of the Company's Intellectual Property and
Econolite Intellectual Property as may be necessary to make, design, develop,
assemble, manufacture, and repair the Solo product solely for sale to ISS and
Econolite. Cohu acquired no right, title, or interest in or to the Company's
Intellectual Property or the Econolite Intellectual Property other than the
foregoing limited license, nor does Cohu have the right or authority to
sublicense all or any portion of the Company's Intellectual Property or
Econolite Intellectual Property.

         Cohu agreed to manufacture and sell exclusively to ISS and Econolite so
many units of the Solo product as ISS and Econolite may order from time to time.
ISS and Econolite each agreed to purchase from Cohu all of their respective
requirements for the Solo product for sale to end users in the Company's and
Econolite's territories until such time as ISS and/or Econolite have purchased
5,000 units in the aggregate. Econolite agreed to continue to purchase all of
its requirements for the Solo product thereafter, subject to Econolite's option
to manufacture the Solo product and the Company's right of termination.
Notwithstanding the foregoing, nothing in the Production Agreement requires
either ISS or Econolite to purchase a minimum number of units from Cohu.

         ISS may terminate the Production Agreement, with or without cause, upon
sixty days' prior written notice. Cohu may terminate the Production Agreement,
with or without cause, upon twelve months' prior written notice. In the event
ISS terminates the Production Agreement with cause, Cohu shall promptly deliver
to ISS all tooling specific to production of the Solo product, and Cohu shall
not be entitled to any further payment for development services.

          In the event ISS terminates the Production Agreement without cause as
provided in the agreement, ISS will purchase from Cohu all of Cohu's inventory
related solely to the manufacture or sale, including raw materials, unique
parts, work in process, and finished goods up to a maximum purchase price of
$90,000. The purchase price of such inventory would be at Cohu's cost.

         Econolite provides a two-year warranty on the current Autoscope system
and must provide all service required under such warranties. Cohu provides a
two-year warranty to ISS and Econolite on the Solo product. Some of the
component hardware incorporated into the Autoscope system, such as the
supervisor computer and the video monitor, are standard computer hardware
products that are available from multiple sources. Other parts, such as the
microprocessor and digitizer are manufactured to certain specifications by third
party vendors for integration into the system. While current vendors of
components for the Autoscope system are meeting Econolite's, Cohu's and the
Company's quality and performance expectations, the Company believes alternative
component vendors are available should the necessity arise. Nevertheless,
shortages of parts or the need to change vendors could adversely affect
Econolite's or Cohu's ability to manufacture the Autoscope system, which could,
in turn, adversely affect the Company's business.

         The Company continues to strengthen its sales and marketing effort by
investing in promotional activities to support Econolite's marketing efforts in
the Econolite Territory. As part of this effort, ISS and Econolite have an
integrated marketing communications program. This program attempts to increase
market awareness of the Company's technology and its product. ISS and Econolite
have engaged in direct mailings of Autoscope brochures, manuals and videos to
potential customers.

         ISS has established a sales and marketing capability in countries
outside the Econolite Territory. In November 1998, the Company employed a
Director of Asian Operations to be responsible for sales and marketing efforts,
including revitalization and growth of distributors in this market. In addition,
on February 1, 1999, the Company acquired a sixty- percent equity interest in a
sales organization in Hong Kong. This affiliate, under the direction of the
Director of Asian Operations, will market the Company's products as well as
related traffic control products in Asia.

         The Company also employs a business development manager to expand the
distribution network in Europe and Latin America. The Company currently has
distributor agreements with twenty-one distributors covering countries primarily
in Europe, Asia, and South America. Under the distributor agreements each
distributor agrees to use its best efforts to market and sell the Autoscope
system and to purchase one demonstration system of the Autoscope for use in its
marketing efforts.

PATENTS AND PROPRIETARY RIGHTS

         The Company intends to actively protect its intellectual property
assets and will actively seek, when appropriate, protection for owned or
licensed products and proprietary information by means of U.S. and foreign
patents, trademarks, and contractual arrangements. In addition, the 



                                       11
<PAGE>

Company relies upon trade secrets and contractual arrangements to protect
certain of its proprietary information. The Company has a federally registered
trademark right to "Autoscope."

         The technology underlying the Autoscope system was initially developed
by Dr. Panos Michalopoulos, Chairman of the Board and Chief Scientific Advisor
of ISS and a Professor at the University of Minnesota, and was further developed
at the University of Minnesota from 1985 to 1991 with involvement by Dr.
Michalopoulos. Additional system developments were funded, in part, by the
Minnesota Department of Transportation and the Federal Highway Administration
from 1985 to 1989. The U.S. patent for certain aspects of the technology
underlying the Autoscope system was issued in 1989 to the University of
Minnesota. The University of Minnesota has filed to perfect related patents in
France, Germany, the United Kingdom, and Japan. Dr. Michalopoulos has assigned
all of his rights in such technology to the Company or to the University of
Minnesota. The Company entered into a License Agreement (the License Agreement)
with the University of Minnesota in 1991.

         Under the License Agreement, the Company has been granted an exclusive,
worldwide license, with a right to grant sublicenses, to make, have made, use,
sell, and lease any product that incorporates knowledge, information, know-how,
software and devices, whether patentable or not, in the possession of the
University and related to a video vehicle detection system developed by the
University of Minnesota, solely or jointly with the Company, including certain
improvements made to such technology. In exchange for that license, the Company
pays to the University of Minnesota (i) a royalty of 3% of the net sales of
licensed products, (ii) 50% of all site license revenue, and (iii) 10% of all
sublicensing revenue. For purposes of the License Agreement, net sales means the
gross amount collected for sales, leases or licenses of licensed products.
Licensed products include any manufactured product that incorporates the
technology or improvements covered by the License Agreement. Site license
revenue equals all revenue collected by the Company and specifically allocable
to the Company for granting a license to use the licensed products at a specific
location or by a specific user. Sublicensing revenue equals all revenue
collected by the Company from parties to whom the Company grants sublicense
rights to make or sell the licensed products. The University of Minnesota has
retained a nonexclusive and nontransferable right to use the licensed technology
for educational and research purposes. The License Agreement terminates at the
termination of the patent covering the technology. The University of Minnesota
may terminate the License Agreement if the royalties due thereunder are unpaid,
if there is a material breach of the agreement by the Company or if the Company
fails to use best efforts to effect commercial sales of the licensed products.
The Company has agreed to indemnify the University of Minnesota against all
liabilities or losses arising from (i) manufacture, use, lease or sale of a
licensed product by the Company or a sublicensee of the Company, or (ii) a third
party's use of a licensed product purchased from the Company or a sublicensee of
the Company or (iii) a third party's manufacture of a licensed product at the
request of the Company.

         The Company has sublicensed certain of its rights in the Autoscope
technology to Econolite pursuant to the Econolite Agreement. See "Marketing and
Manufacturing" above.



                                       12

         The Company's technology is dependent upon the knowledge, experience,
and skills of its key scientific and technical personnel. To protect its rights
to its proprietary know-how and technology, Company policy requires all
employees and consultants to execute confidentiality agreements that prohibit
the disclosure of confidential information to anyone outside the Company. These
agreements also require disclosure and assignment to the Company of any
discoveries and inventions made by such persons while devoted to Company
activities.

EMPLOYEES

         As of March 18, 1999, the Company had 23 full time employees, of which
11 were engaged in research and development; 5 in product and customer support;
2 in sales and marketing; and 5 in management, administration, finance, and
human resources. No employee is represented by a union. The Company believes its
employee relations are good.

LIABILITY INSURANCE

         Econolite currently maintains $15,000,000 of product liability
insurance, and ISS maintains $2,000,000 of product liability insurance. In
addition, Econolite has agreed to indemnify and hold harmless ISS from and
against any losses, damages, or expenses arising out of the products made or
sold by Econolite pursuant to the Econolite Agreement. There can be no assurance
that the Company will be able to obtain adequate insurance in the future or that
claims will not be made in excess of any insurance coverage obtained.


 ITEM 2.          DESCRIPTION OF PROPERTY

                  The Company currently leases approximately 10,000 square feet
                  of office space in St. Paul, Minnesota. The lease expires in
                  November 2001, with an option to extend the lease through
                  November 2004. Aggregate annual lease payments under the lease
                  are approximately $138,000. The Company believes its
                  facilities are sufficient for its current needs.

ITEM 3.           LEGAL PROCEEDINGS

                  During 1998, the Company was not involved in any legal
                  proceedings.

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

                  There were no matters submitted to a vote of security holders
                  during the fourth quarter of the calendar year covered by this
                  report.

                  The Company has never declared or paid a cash dividend on its
                  Common Stock. The Company currently intends to retain earnings
                  for use in the operation and expansion of its business; and
                  therefore, it does not anticipate paying any dividends in the
                  foreseeable future.

Mr. William L. Russell
Image Sensing Systems, Inc.
500 Spruce Tree Center
1600 University Avenue West
St. Paul, Minnesota 55104-3825

Dear Mr. Russell:


We are pleased to advise you that Norwest Bank Minnesota, National Association
(the "Bank") has renewed a secured, revolving, Conditional Credit Line (the
"Line") for Imaging Sensing Systems, Inc. in an amount not to exceed $500,000.
You may prepay and re-borrow as long as no borrowing causes that dollar limit to
be exceeded.

The Revolving Credit Line is subject to the terms and conditions outlined below:

o    Credit Advances. Loans made under the Line will be at the Bank Officers'
     sole discretion, that is, the Officers have no obligation to make any loan
     under the Line. The Officers will make a separate credit decision each time
     a request is made.

o    The Note. Your obligation to repay all loans made by us under the Line will
     be evidenced by a single promissory note due on demand with a final
     maturity of July 31, 2000. This note will also specify events of default
     and the rights and remedies available to us upon the occurrence of an event
     of default.

o    Interest Rate. The Note will bear interest (computed on the basis of actual
     days elapsed in a 360-day year) on the principal balance outstanding.
     Interest accrues from the date of the initial advance until the Note is
     paid in full at a floating rate of 1.25% per annum in excess of the Base
     Rate of Norwest Bank Minnesota, N.A.. The rate of interest shall be
     adjusted with each change in the Base Rate.

o    Adverse Conditions. The Line may be terminated at any time by the Bank by
     written notice to the Borrower and shall terminate automatically, without
     notice, if materially adverse conditions develop at any time, whether
     before or after acceptance of this letter. If the Line is terminated, each
     and every note evidencing loans, if any, made under the Line will be
     immediately due and payable.

o    Security. The Note is secured by a security interest in your accounts
     receivable, inventory, equipment and general intangibles. This property is
     more fully described in the security agreement. The security interest
     extends to property of the type described, whether now owned or hereafter
     acquired.

     o    Accounts Receivable. All loan advances will not exceed 65% of eligible
          accounts receivable. We define ineligible accounts receivable as
          follows:


<PAGE>



          o    Those receivables that are more than 90 days old.

          o    Those receivables subject to the 10% rule (i.e. any account in
               which 10% or more of the total outstanding receivable is
               delinquent 90 or more days will be entirely ineligible).

          o    Contra accounts - those accounts subject to offset, dispute or
               retainage.

          o    Those receivables due from the U.S. Government, foreign entities
               (unless insured or backed by Documentary Letters of Credit), or
               affiliates or subsidiaries of the Borrower.

          Insurance. Borrower will maintain insurance with financially sound and
          reputable insurers covering properties and business against those
          casualties and contingencies and in the types and amounts as are in
          accordance with sound business and industry practices, with the Bank
          named as loss payee.

          Collateral Audits. The Borrower will allow the Bank to conduct annual
          collateral audits of its books and records, if the Bank chooses to do
          so. The audits will be performed by Norwest's collateral audit team,
          and all costs associated with the audits will be paid by the Borrower.

FINANCIAL AND AFFIRMATIVE COVENANTS

So long as the Line is in effect, the Borrower will:

o    Maintain its primary depository accounts at Norwest Bank Minnesota, N.A. -
     St. Paul office.

o    Maintain Tangible Net Worth of not less than $3,000,000 as of 12/31/98.

o    Achieve Net Earnings after Tax in fiscal 1998 of at least $1.00.

o    Maintain Debt to Tangible Net Worth of no more than 0.50:1 as of 12/31/98.

NEGATIVE COVENANTS

So long as the Line is in effect, and without the written consent of the Bank,
the Borrower will not:

o    Consolidate with, or merge into, any other corporation, or permit any other
     corporation to merge into it, nor will it convey, lease or sell all or a
     material portion of its assets or business, except in the ordinary course
     of business; nor will it lease, purchase, or acquire all or a material
     portion of the assets or business of any other corporation or entity.

o    Purchase or acquire any securities of, or make any investments in any
     person, firm or corporation, except obligations of the United States
     Government, open market commercial paper rated prime, or certificates of
     deposit in commercial banks.

o    Incur indebtedness for borrowed money or installment obligations, except
     indebtedness to the Bank and existing indebtedness disclosed to the Bank in
     writing.

o    Create, or permit to exist, any lien on any of its property, real or
     personal, except liens to secure permitted indebtedness, liens to the Bank,
     and liens incurred in the ordinary course of business.

                                 LEASE AGREEMENT

          THIS LEASE AGREEMENT, made and entered into this 24th day of November
1998 by and between Spruce Tree Centre L.L.P. (hereinafter referred to as
"Lessor"), and Image Sensing Systems, Inc. (hereinafter referred to as "Tenant",
whether one or more).

WITNESSETH:

PREMISES AND TERMS

          1. In consideration of the obligation of Tenant to pay rent as herein
provided, and in consideration of the other terms, provisions and covenants
hereof, Lessor hereby demises and leases to Tenant, and Tenant hereby takes from
Lessor, certain premises (hereinafter referred to as the "Leased Premises")
situated within the County of Ramsey, State of Minnesota, consisting of
approximately 9,278 rentable square feet; known as Suites 420 and 500, as shaded
with cross-hatch on the floor plan attached hereto as Exhibit A and made a part
hereof including a proportionate share of common area as described under the
definition of Rentable Area (Articles 6a, 6b and 6c of this Lease), on the
fourth and fifth floors of the building commonly known as Spruce Tree Centre
(hereinafter referred to as the "Building") located at 1600 University Avenue,
St. Paul, Minnesota 55104, which Building is situated upon the real property
described on Exhibit B attached hereto and hereby made a part hereof (the
Building and said real property are hereinafter referred to as the "Project"),
together with all rights, privileges, easements, appurtenances and amenities
belonging to or in any way pertaining to the Leased Premises, and together with
the right to use in common with Lessor and other tenants in the Project, and its
and their employees, agents, representatives and invitees, any common areas and
facilities of the Project.

                  To have and to hold for a term of three (3) years and no
months, commencing on the first day of December , 1998, and ending on the 30th
day of November, 2001. Tenant acknowledges that it has inspected the Leased
Premises and accepts them in their present condition as suitable for the purpose
for which they are leased, and further acknowledges that no representations as
to the repair of the Leased Premises nor promises to alter, remodel or improve
the Leased Premises have been made by Lessor or its agents, except as may be
provided on the attached Exhibit C.

ACCEPTANCE OF PREMISES

          2. If Lessor does not complete leasehold improvements, as described in
Exhibit C, if any, to be completed by Lessor, and deliver possession of the
Leased Premises on or before said commencement date, or if Lessor is unable for
any other reason to deliver possession of the Leased Premises by such date,
Lessor shall not thereby be deemed to be in default hereunder, and shall not
thereby be liable to Tenant for any loss, damage, cost and expense suffered or
incurred by Tenant, nor shall the commencement date of the lease or the term of
the Lease be affected or changed thereby, and Tenant agrees to accept possession
of the Leased Premises at such time as Lessor is able to tender the same;
provided, however, Lessor hereby waives payment of rent covering any period
prior to the tendering of possession to Tenant hereunder, except as otherwise
provided on the attached Exhibit C.

                                        1

BASE RENT

         3a. Tenant shall pay to Lessor during the Lease Term:

         YEAR             DATES          ANNUAL RENT     MONTHLY RENT
         ------------------------------------------------------------
         1    12/01/1998 - 11/30/1999     $65,873.80       $5,489.48
         2    12/01/1999 - 11/30/2000      67,850.00        5,654.17
         3    12/01/2000 - 11/30/2001      69,885.50        5,823.79

payable in advance on the first day of each month during the Lease Term in
lawful money of the United States, to Lessor without any deduction, offset,
counterclaim or reduction whatsoever, at the office of Garsten/Perennial
Management Corporation, Spruce Tree Centre, Suite 310, 1600 University Avenue,
St. Paul, Minnesota 55104, or such other place as Lessor shall designate.

         3b. In the event the Lease Tenn commences on a day other than the first
day of a month, or terminates on a day other than the last day of a month, or
both, the rent, including any adjustments therein made in accordance with this
Lease, payable during such first or last month, shall be adjusted on a prorata
basis.

         3c. All Fixed rent and other sums payable hereunder by Tenant ("Rent")
which are not paid within ten (10) days after due shall bear interest from the
date paid at the rate of twelve percent (12%) per annum, or the highest rate
permitted by law, whichever is less.

TAX PAYMENT

         4a. In addition to Fixed rent, Tenant shall, each year during the Tenn
of this Lease or any extensions or renewals thereof, pay its pro rata share
(equal to a fraction, the numerator of which is the rentable area of the Leased
Premises and the denominator of which is the total rentable square feet of
office area in the Project) of the amount of the general real estate taxes and
installments of special assessments due and payable with respect to the Project
in such year ("Tax Costs"), including any payments made by Lessor to any
governmental body either "in lieu of taxes" or as an additional tax or
assessment of any kind associated in whole or part with the project but
excluding any income taxes paid by Lessor resulting from its ownership of the
building. Such payment by Tenant shall be paid at the same time as Monthly Fixed
rent in equal monthly installments, as estimated by Lessor, representing 1/12 of
the Tax Costs due and payable in any such year, which initially shall be
estimated at a rate of $3.40 per square foot of rentable area in the Leased
Premises ("Base Tax Costs"). Prior to the commencement of the Lease Term and
prior to March I of each ensuing calendar year, or as soon as is practicable
thereafter, Lessor shall furnish Tenant with an estimate of the Tax Costs (if
such estimate is higher than the Base Tax Costs) for the then current calendar
year, and the new monthly amount payable on the first day of each month during
the remainder of such calendar year. Within ten (10) days after Lessor furnishes
Tenant with such estimate, Tenant shall also pay to Lessor, as an additional
payment, any amount due for any monthly periods prior to the date Lessor issued
its revised estimate of Tax Costs, if such amount exceeds the payments made by
Tenant for such monthly periods.

                                        2


<PAGE>


         4b. After expiration of each calendar year during the Lease Term,
through and including the calendar year in which the Lease Term expires, Lessor
shall furnish Tenant with a statement of the actual Tax Costs for the
immediately preceding calendar year. If the actual Tax Costs differ from the
estimated Tax Costs, within ten (10) days after Lessor has furnished such
statement to Tenant, Tenant shall pay to Lessor for any shortage for the
immediately preceding calendar year, or Lessor shall refund to Tenant any
overpayment for the preceding calendar year, as the case may be.

         4c. If the first or last day of the Lease Term occurs on a day other
than the first or last day, respectively, of a calendar year, then Tenant's
obligation under this Article 4 shall be pro rated based on a 365 day calendar
year.

         4d. Lessor's reasonable determination of Tax Costs, both estimated and
actual, shall be binding upon Tenant. Lessor has the right in its sole
discretion to determine the rentable area of the Leased Premises and the
Project.

         4e. Tenant's failure to pay any amounts due under this Article 4 when
due shall be treated in the same manner as a default in the payment of Fixed
rent.

OPERATING COST PAYMENT

         5a. In addition to Fixed rent, Tenant shall, each year during the Term
of this Lease or any extensions or renewals thereof, pay its pro rata share
(equal to a fraction, the numerator of which is the rentable area of the Leased
Premises and the denominator of which is the total rentable square feet of
office area in the Project) of the total "Operating Costs" (as defined below)
for the Project in such year. Such payment by Tenant shall be paid at the same
time as Monthly Fixed rent in equal monthly installments, as estimated by
Lessor, representing 1/12 of the Operating Costs for any such year, which
initially shall be estimated at a rate of $ 4.72 per square foot of rentable
area in the Leased Premises ("Base Operating Costs"). Prior to the commencement
of the Lease Term and within 30 days after the expiration of each ensuing
calendar year, or as soon as is practicable thereafter, Lessor shall furnish
Tenant with an estimate of the Operating Costs (if such estimate is higher than
the Base Operating Costs) for the then current calendar year, and the new
monthly amount payable on the first day of each month during the remainder of
such calendar year. Within ten (10) days after Lessor furnishes Tenant with such
estimate, Tenant shall also pay to Lessor, as an additional payment, any amount
due for any monthly periods prior to the date Lessor issued its revised estimate
of Operating Costs, if such amount exceeds the payments made by Tenant for such
monthly periods.

         5b. Within 30 days after expiration of each calendar year during the
Lease Term, through and including the calendar year in which the Lease Tenn
expires, Lessor shall furnish Tenant with a statement of the actual Operating
Costs for the immediately preceding calendar year. If the actual Operating Costs
differ from the estimated Operating Costs, within ten (10) days after Lessor has
furnished such statement to Tenant, Tenant shall pay to Lessor for any shortage
for the immediately preceding calendar year, or Lessor shall refund to Tenant
any overpayment for the preceding calendar year, as the case may be.

          5c. If the first or last day of the Lease Term occurs on a day other
than the first or last day, respectively, of a calendar year, then Tenant's
obligation under this Article 5 shall be pro rated based on a 365 day calendar
year.

every kind and nature which Lessor incurs, pays or becomes obligated to pay in
owning, maintaining, managing (including management fees), insuring and
operating the Project, the adjacent parking ramp when applicable and every part
thereof exclusive of depreciation, interest or payments of any principal on any
mortgage. Without limiting the generality of the foregoing, Operating Costs
shall include amortization of capital expenditures that produce a reduction in
energy or other Operating Costs, to the extent that Operating Costs are thereby
reduced, over such reasonable period as Lessor shall determine, together with
interest at the rate of 12% per annum on the unamortized balance. If, as a
result of such capital expenditure, Lessor eliminates an item of Operating Costs
which was included in Base Operating Costs, Base Operating Costs shall be
reduced by the amount of such eliminated item for purposes of this Article.

         5e. Lessor's reasonable determination of Operating Costs, both
estimated and actual, shall be binding upon Tenant. Lessor has the right in its
sole discretion to determine the rentable area of the Leased Premises and the
Project.

         5f. Tenant's failure to pay any amounts due under this Article 5 when
due shall be treated in the same manner as a default in the payment of Fixed
rent.

RENTABLE AREA

         6a. Rentable area of a single tenancy floor, whether above or below
grade, shall be computed by measuring to the outside finish of permanent outer
building walls, or from the glass line where at least 50% of the outer building
wall is glass. Rentable area shall include all area within outside walls less
stairs, elevator shafts, flues, pipe shafts, and vertical ducts, and not
actually available to the Tenant for its furnishings and personnel, and their
enclosing walls. Toilet rooms within and exclusively serving only that floor
shall be included in rentable area.

         6b. Rentable area for a partial floor shall include all space within
the demising; walls (measured from the midpoint of demising walls and in the
case of exterior walls measured as set forth in (a) above), excluding vertical

vents, stacks, pipe shafts, and vertical ducts, plus Tenant's proportionate
share of the common areas such as lobbies, corridors, toilet and mechanical
rooms, telephone and electrical closets, and service areas in the Project.
Vertical penetrations which are for a specific use of Tenant, such as special
stairs or elevators, shall be included as rentable area. No deductions from
rentable area will be made for columns or projections necessary to the support
of the Project.

         6c. For purposes of computing rentable area, tenants' share of common
area shall be a factor of .15. Rentable area = usable area / .85. For purposes
of this lease, rentable area shall be 9,278 rentable square feet.

Hundred Dollars ($5,500.00 ). Said sum shall be held by Lessor as security for
the faithful performance by Tenant of all the terms, covenants and conditions of
this Lease to be kept and performed by Tenant during the Lease Term. No interest
shall be payable on said deposit. If Tenant defaults with respect to any
provision of this Lease, including, but not limited to the provisions relating
to the payment of Rent, Lessor may (but shall not be required to, use, apply or
retain all or any part of said security deposit for the payment of any Rent or
any other sum in default, or for the payment of any amount which Lessor may
spend or become obligated to spend by reason of Tenant's default, or to
compensate Lessor for any other loss or damage which Lessor may suffer by reason
of Tenant's default. If any portion of said security deposit is so used or
applied, Tenant shall, within five (5) days after written demand therefor,
deposit cash with Lessor in an amount sufficient to restore said security
deposit to its original amount and Tenant's failure to do so shall be a material
breach of this Lease. If Tenant shall fully and faithfully perform every
provision of this Lease to be performed by it, the security deposit or any
balance thereof shall be returned to Tenant (or, at Lessor's option, to the last
assignee of Tenant's interest hereunder) at the expiration of the Lease Term. In
the event Lessor assigns its interest in this Lease, Lessor shall transfer said
security deposit to Lessor's successor in interest.

ACCOUNTING

         8. Lessor shall, in its reasonable discretion, determine, from time to
time, the method of computing operating costs, the allocation of operating costs
to various types of space within the Project and the extent of the appurtenances
to the Project, and Tenant shall be bound thereby. Notwithstanding the
foregoing, no decrease in Tax Costs and/or Operating Costs shall reduce Tenant's
rent below the annual Fixed rent set forth in Article 3 above.

style, place and materials, as shall first have been approved by the Lessor. The
listing of any name other than that of the Tenant, whether on the doors of the

representatives may at any time in case of emergency enter the Leased Premises
and do such acts as Lessor may deem proper in order to protect the Leased

to pay a public utility company or independent contractor. Charges for any such
utilities or services, whether or not furnished by Lessor, shall be paid by
Tenant within ten (10) days after receipt by Tenant of a statement of charges
therefor, and, in the event such charges are not paid when due, may, at the
option of Lessor, be added to and become a part of the next rental installment
coming due hereunder.

interruption or failure of such services incident to the making of repairs,
alterations or improvements or due to casualties, riots, strikes, picketing,
accidents, breakdowns or any cause beyond Lessor's reasonable control or
temporary failure or lack of such services shall be deemed an eviction of Tenant

required information concerning the proposed assignee, and the satisfaction of
all of the conditions specified in Sub-Articles 17a through 17g above, Lessor
shall have the following options:

                  (1)      To cancel this Lease and upon such cancellation, all

                           Lessor's consent to the proposed assignment may be
                           withheld or granted in its sole and absolute

other casualty and this Lease is not thereby terminated, the Lessor shall, at
its expense, restore the Leased Premises, exclusive of any improvements or other
changes made to the Leased Premises by the Tenant, to as near the condition
which existed immediately prior to such damage or destruction as reasonably
possible, and Fixed rent and any other Rent shall abate during such period of
time as the Leased Premises are untenantable in the proportion that the

of personal property, any furniture, equipment, improvements or other changes
made by the Tenant in, on or about the Leased Premises regardless of the cause
of the damage or destruction.

taken by eminent domain, Lessor shall have the right to terminate this Lease by
giving written notice thereof to Tenant within ninety (90) days after the date
of taking. If a portion of the Leased Premises is taken by eminent domain and
this Lease is not thereby terminated, Lessor shall, at its expense, restore the
Leased Premises, exclusive of any improvements or other changes made to the
Premises by Tenant, to as near the condition which existed immediately prior to
the date of taking as reasonably possible, and Rent shall abate during such
period of time as the Leased Premises are untenantable, in the proportion that
the untenantable portion of the Leased Premises bears to the entire Leased
Premises. All damages awarded for a taking under the power of eminent domain,
whether for the whole or a part of the Leased Premises, shall belong to, and be
the property of Lessor, whether such damages shall be awarded as compensation
for diminution in value to the leasehold estate hereby created or to the fee of
the Leased Premises; provided, however, that Lessor shall not be entitled to any
separate award made to Tenant for loss of business, fair value of, and cost of
removal of stock and fixtures. The term "eminent domain" shall include the
exercise of any similar governmental power and any purchase or other acquisition
in lieu of condemnation.

HOLDING OVER

          22. Should Tenant, or any of its successors in interest, hold over the
Leased Premises or any part thereof, after the expiration of the term of this
Lease, such holding over, at the sole election of Lessor, shall constitute and
be construed as a tenancy from month to month only. The inclusion of the
preceding sentence shall not be construed as Lessor's permission for Tenant to
hold over. Holdovers may be charged up to twice the Rent in effect at the
expiration of the Lease Term.

QUIET ENJOYMENT

          23. Lessor covenants that if Tenant pays the Fixed rent or any other
Rent, and all other charges provided for in this Lease, performs all of its
obligations provided for under this Lease, and observes all of the other
provisions of this Lease, Tenant shall peaceably and quietly enjoy the Demised
Premises in accordance with the terms of this Lease without any interruption or
disturbance from Lessor. Lessor shall not be responsible or liable for the
actions of third parties, including other tenants in the building.

EVENTS OF DEFAULT

          24. The following events shall be deemed to be events of default by
Tenant under this Lease:

          24a. Tenant shall fail to pay any installments of Fixed rent hereby
reserved or any other Rent when due or any other charge payable hereunder when
due.

          24b. Tenant shall become insolvent, or shall make a transfer in fraud
of creditors, or shall make an assignment for the benefit of creditors.

          24c. Tenant shall file a petition under any section or chapter of the
National Bankruptcy Act, as amended, or under any similar law or statute of the
United States or any state thereof, or Tenant shall be adjudged bankrupt or
insolvent in proceedings filed against Tenant thereunder.

          24d. A receiver or trustee shall be appointed for all or substantially
all of the assets of Tenant.

          24e. Tenant shall desert or vacate any substantial portion of the
Leased Premises.

          24f. Tenant shall cause or suffer a lien to be filed against the
Project or any part thereof.

          24g. Tenant shall fail to comply with any term, provision or covenant
of this Lease (other than the foregoing in this Article 24) and shall not cure
such failure within ten (10) days after notice from Lessor.



                                       13

DEFAULT

         25a. Tenant hereby agrees that in case Tenant shall default in making
its payments hereunder or in performing any of the other agreements, terms, and
conditions of this Lease, then, in any such event, Lessor, in addition to all
other rights and remedies available to Lessor by law or by other provisions
hereof, at Lessor's option, may reenter and recover possession of the Leased
Premises (with or without terminating this Lease) and/or may annul and cancel
this Lease as to all future rights of Tenants. Tenant further agrees that in
case of any such termination Tenant will indemnify the Lessor against all loss
of rents and other damage which Lessor may incur by reason of such termination,
including, but not limited to, costs of restoring and repairing the Leased
Premises and putting the same in rentable condition, costs of renting the Leased
Premises to another tenant, loss or diminution of rents and other damage which
Lessor may incur by reason of such termination and all reasonable attorney fees
and expenses incurred in enforcing any of the terms of this Lease. Neither
acceptance of rent by Lessor, with or without knowledge of breach, nor failure
of Lessor to take action on account of any breach hereof, or to enforce its
rights hereunder shall be deemed a waiver of any breach and absent written
notice or consent said breach shall be a continuing one.

         25b. In the event Tenant fails to pay any installment of Fixed rent or
any other Rent hereunder as and when such installment is due, or any other
charge payable hereunder as and when such charge is due, Tenant, if permitted by
law, shall pay to Lessor on demand a late charge in an amount equal to five
percent (5%) of such installment or such other charge, or $250.00, whichever is
less, and failure to pay such late charge within ten (10) days after the date
due shall be an event of default hereunder. The provision for such late charge
shall be in addition to all of Lessor's other rights and remedies hereunder or
at law and shall not be construed as liquidated damages or as limiting Lessor's
remedies in any manner.

SUBORDINATION OF LEASE NOTICES

         26. The rights of the Tenant under this Lease shall be and are subject
and subordinate at all times to all ground leases, and/or underlying leases, if
any, now or hereafter in force against the Project, and to any mortgage or
mortgages now or hereafter in force against such leases and/or the Project, and
to all advances made or hereafter to be made upon the security thereof, and to
all renewals, modifications, consolidations, replacements and extensions
thereof. This Article 26 is self-operative and no further instrument of
subordination shall be required. In confirmation of such subordination Tenant
shall promptly execute such further instruments as may be requested by the
Lessor. The Tenant hereby irrevocably appoints the Lessor as attorney-in-fact
for the Tenant with full power and authority to execute and deliver in the name
of the Tenant any such instrument or instruments. Tenant at the option of any
mortgagee, or the lessor under any such ground lease or underlying lease, agrees
to attorn to such mortgagee or lessor in the event of a foreclosure sale or deed
in lieu thereof or termination by the lessor of any such lease. Failure of the
Tenant to execute any of the above instruments within fifteen (15) days upon
written request to do so by Lessor shall constitute a breach of this Lease and
the Lessor may, at its option, in addition to any other remedies, cancel this
Lease and terminate the Tenant's interest therein.

         27a. Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment
by Lessor to Tenant or by Tenant to Lessor shall be deemed to be complied with,
when and if, the following steps set forth in Article 27b are taken.

requirements, directives or requests, or if Lessor deems such action to be for
the benefit of our national interest or the general public. Without limiting the
generality of the foregoing, Lessor may reduce the quantity and quality of all
utility and other services and impose such regulations as the Lessor deems
necessary in order to conserve energy, and may change the normal hours of
operation of the Project. Utility in the sense of this Article 29 includes, but
is not limited to heating, cooling, electricity, water and all the sources of
energy needed to provide such.

including but not limited to all communications and electronic systems, office
furniture and supplies, signs, replacement of stationary and business cards,
reasonable costs associated with notices of change of address, and all other
reasonable expenses except for inconvenience. Lessor shall choose a responsible
mover or may use Lessor's own personnel. Fragile contents shall be moved by
tenant at tenant's expense. Moving shall be accomplished as quickly as possible
and Lessor shall accede to tenant's demands to move on a weekend if so
instructed.

LESSOR'S USE

          33. It is understood that Lessor may occupy portions of the Project in

MISCELLANEOUS TAXES

         34a. Tenant shall pay prior to delinquency all taxes assessed against
or levied upon its occupancy of the Leased Premises, or upon the fixtures,
furnishings, equipment and personal property of Tenant located in the Leased
Premises, if nonpayment thereof shall or would give rise to a lien on the
Project or any part thereof, and when possible, Tenant shall cause said
fixtures, furnishings, equipment and personal property to be assessed and billed
separately from the property of Lessor. In the event any or all of Tenant's
fixtures, furnishings, equipment and personal property, or Tenant's occupancy of
the Leased Premises, shall be assessed and taxed with the property of Lessor,
Tenant shall pay to Lessor its share of such taxes within ten (10) days after
delivery to Tenant by Lessor of a statement in writing setting forth the amount
of such taxes applicable to Tenant's fixtures, furnishings, equipment or
personal property, or occupancy of the Leased Premises.

         34b. If, under the laws of the United States or any state thereof or
any political subdivision in which the Leased Premises are situated, a tax or
excise on rents or other tax, however described, is levied or assessed against
Lessor or the rent reserved hereunder, in addition to, in lieu of or as a
substitute in whole or in part for taxes and assessments commonly known as real
estate taxes, Tenant shall pay and discharge such tax or excise on rents or
other tax, but only to the extent of the amount thereof which is lawfully
assessed or imposed upon Lessor, and which was so assessed or imposed as a
direct result of Lessor's ownership of the Leased Premises or of this Lease, or
of the rental accruing under this Lease.

ESTOPPEL CERTIFICATE

continue and remain in full force and effect. The receipt by Lessor of rents
with knowledge of a breach in any of the terms, covenants or conditions of the

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


The following table sets forth, for the periods indicated, certain statement of
operations data as a percent of revenue:

YEAR ENDED DECEMBER 31                              1998                  1997

Product sales for 1998 decreased to $881,000 compared to $1,434,000 in 1997. The
decrease was due primarily to fewer sales in Asia, $140,000 in 1998 compared to
$453,000 in 1997, and less sales to the Minnesota Department of Transportation
(MnDOT) for test sites, $330,000 in 1998 compared to $569,000 in 1997. Royalty
income decreased to $2,216,000 in 1998 compared to $2,742,000 in 1997. The
decrease was due to less sales and upgrades of Autoscope systems by Econolite
Control Products, Inc. (Econolite), our North American manufacturing and
distribution partner. The Company believes Econolite's sales of Autoscope
systems were affected by the nine-month delay in the U. S. Congress in passing
the U. S. transportation bill. Federal funding is generally critical for major
municipal and state projects that use the Company's Autoscope technology.
Revenue from consulting services increased to $271,000 in 1998 from $152,000 in
1997. The increase resulted primarily from assignment of more technical
resources to consulting projects in 1998.
    Gross profits were $2,624,000 or 77.9% of revenue in 1998, compared to
$3,143,000 or 72.6% of revenue in 1997. The increase in gross profit margin was
due primarily to a more favorable mix of revenues as well as improved margins on
product sales and consulting projects.
    Selling, marketing and product support expenses were $1,006,000 or 29.9% of
revenue in 1998, compared to $1,051,000 or 24.2% of revenue in 1997. The
decrease resulted primarily from reduced spending for sales and marketing
personnel and less costs for international travel. General and administrative
expenses were $1,303,000 or 38.7% of revenue in 1998, compared to $1,052,000 or
24.3% of revenue in 1997. The increase was due primarily to severance pay for
the outgoing CEO and recruitment costs for the new CEO.
    Research and development expenses were $203,000 or 6.0% of revenue in 1998,
compared to $643,000 or 14.9% of revenue in 1997. The decrease was due to
capitalization of $825,000 in software development costs in 1998 compared to
$75,000 in 1997. The Company capitalized software development costs for its new
Autoscope Solo product during the application development stage, which took
place from December 1997 through October 1998. The combination of research and
development expenses and capitalized software development costs was $1,028,000
in 1998 compared to $718,000 in 1997. The increase resulted primarily from
expediting completion of the new Autoscope Solo product.
    Net income was $209,000 or 6.2% of revenue in 1998, compared to $487,000 or
11.3% of revenue in 1997. There was no tax provision in 1998 primarily due to a
decrease in the Company's valuation allowance. In 1997, the Company was able to
utilize operating loss carryforwards to offset all of its taxable income.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1998 the Company had $1,326,000 in cash and cash equivalents
compared to $2,000,000 at December 31, 1997. The Company had working capital of
$2,073, 000 and a current ratio of 3.5 to 1 at December 31, 1998 compared to
$2,533,000 and 3.8 to 1 at the end of 1997. The decrease in liquidity in 1998
was due primarily to investment in the Autoscope Solo product, including
capitalized software development costs. Net cash provided by operating
activities was $249,000 in 1998, compared to $393,000 in 1997. The decrease was
due primarily to reduced earnings and an increase in accounts receivable.
    The Company believes that cash and cash equivalents on hand at December 31,
1998 along with an available $500,000 revolving line of credit with a bank will
satisfy the Company's projected working capital needs and investing activities,
including acquisition of a sixty percent equity interest in a foreign sales
organization, and other cash requirements through 1999.

YEAR 2000 ISSUE

BACKGROUND. Many currently installed computer systems and software are coded to
accept only two-digit entries in the date code fields. These date code fields
will need to accept four-digit entries to distinguish 21st century dates 


10  Image Sensing Systems, Inc.
<PAGE>


from 20th century dates. This problem could result in system failures or
miscalculations causing disruptions of business operations (including, among
other things, a temporary inability to process transactions, send invoices or
engage in other similar business activities). As a result, many companies'
computer systems and software will need to be upgraded or replaced in order to
comply with year 2000 requirements. The potential global impact of the year 2000
problem is not known, and, if not corrected in a timely manner, could affect the
Company and the U.S. and world economies generally.

    STATE OF READINESS. The Company has analyzed the potential effect of the
year 2000 issue on both the system software included in the Company's products
and its internal systems (e.g., word processing and billing software), including
its information technology ("IT") and non-IT systems. The Company's year 2000
compliance program includes the following phases: identifying systems that need
to be modified or replaced; carrying out remediation work to modify existing
systems or convert to new systems; and conducting validation testing of systems
and applications to ensure compliance. The Company is currently in the
remediation phase of this program with respect to software purchased or licensed
from software vendors by the Company and used internally and has completed the
validation phase of this program with respect to its own products.
    The amount of remediation work required to address year 2000 problems is not
expected to be extensive. The Company has tested all of the system software
included in its products and determined that it is year 2000 compliant. In
addition, the Company has requested and received documentation from vendors
supplying software for its primary business applications addressing year 2000
compliance. In all cases, vendors' responses indicated that their applications
were either currently year 2000 compliant or that they would be compliant by the
end of 1998. Therefore, the Company will be required to replace or modify some
of its existing software applications in order for its internal computer systems
to function properly in the year 2000 and thereafter. The Company estimates that
it will complete its year 2000 compliance program for all of its significant
internal systems no later than July 1, 1999. The Company also has had informal
discussions with its major suppliers and customers regarding their efforts to
address the year 2000 problem. These actions are intended to help mitigate the
possible external impact of the year 2000 problem. However, it is impossible to
fully assess the potential consequences in the event service interruptions from
suppliers occur or in the event that there are disruptions in such
infrastructure areas as utilities, communications, transportation, banking and
government.

    COSTS. Because essentially all of the Company's products and internal
systems were created in the last few years, such products and internal systems
were designed to avoid the year 2000 problem. As a result, the total cost for
resolving the Company's year 2000 issues is expected to be less than $35,000, a
negligible amount of which has been spent through December 31, 1998. The total
cost estimate includes the cost of replacing or upgrading non-compliant systems
that were otherwise planned (but perhaps accelerated due to the year 2000 issue)
or which have significant improvements and benefits unrelated to year 2000
issues. Estimates of year 2000 costs are based on numerous assumptions, and
there can be no assurance that the estimates are correct or that actual costs
will not be materially greater than anticipated.

    CONTINGENCY. The Company has not yet developed a contingency plan to provide
for continuity of processing in the event of various problem scenarios, but it
will assess the need to develop such a plan based on the outcome of the
validation phase of all of its systems and any additional results from surveys
of its major suppliers and customers with respect to their year 2000 compliance.

    RISK. Based on its assessments to date, the Company believes it will not
experience any material disruption as a result of year 2000 problems with
respect to its products and the third-party systems it uses for its internal
functions, and, in any event, the Company does not anticipate the year 2000
issues it will encounter will be significantly different than those encountered
by other computer hardware and software manufacturers, including its
competitors. For example, if certain critical third-party providers, such as
those providers supplying electricity, water or telephone service, experience
difficulties resulting in disruption of service to the Company, a shutdown of
the Company's operations at individual facilities could occur for the duration
of the disruption. Assuming no major disruption in service from utility
companies or other critical third-party providers, the Company believes that it
will be able to manage its total year 2000 transition without any material
effect on the Company's results of operations or financial condition.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 1998



NOTE 1
SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS
The Company develops and markets video image processing technology and products
for use in advanced traffic management systems and traffic data collection. The
Company sells its product primarily to foreign distributors of its product and
receives a royalty for sales made by a sublicensee to North American
distributors. The Company also provides technical expertise in image processing,
hardware and software design and traffic management and control. The Company's
products are used primarily by governmental entities.

REVENUE RECOGNITION
Revenue from product sales and royalties from the sale of products by a
sublicensee are recorded upon shipment. Consulting fees are recorded as earned.

CASH AND CASH EQUIVALENTS
The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. Investments classified as
cash equivalents consist of commercial paper. Market value of these investments
approximates cost at December 31, 1998 and 1997.

INVENTORIES
Inventories are primarily finished goods and are valued at the lower of cost or
market on the first-in, first-out (FIFO) method.

PROPERTY AND EQUIPMENT
Property and equipment are stated at cost. Depreciation is computed by the
straight-line method over a three to seven-year period for financial reporting
purposes and by accelerated methods for income tax purposes.

INCOME TAXES
Income taxes are accounted for under the liability method. Deferred income taxes
reflect the effects of temporary differences between the carrying amounts of
assets and liabilities for financial reporting purposes and amounts used for
income tax purposes. 

STOCK-BASED COMPENSATION
The Company follows Accounting Principles Board Opinion No. 25, ACCOUNTING FOR
STOCK ISSUED TO EMPLOYEES ("APB 25"), and related interpretations in accounting
for its stock options. Under APB 25, when the exercise price of stock options
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.
    The Company has adopted the disclosure only provisions of Statement of
Financial Accounting Standards (SFAS) No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION ("STATEMENT 123"). Accordingly, the Company has made pro forma
disclosures of what net income and net income per share would have been had the
provisions of Statement 123 been applied to the Company's stock options.

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

ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED ASSETS
The Company records losses on long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amount.

RESEARCH AND DEVELOPMENT
Research and development costs are charged to operations in the period incurred.

SOFTWARE DEVELOPMENT COSTS
The Company capitalizes software development costs in accordance with the
provisions of SFAS No. 86, ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE TO BE
SOLD, LEASED, OR OTHERWISE MARKETED. Capitalization of software development
costs, including significant product enhancements, begins upon the establishment
of technological feasibility for the product and concludes when the product is
available for release to distributors. The establishment of technological
feasibility and the

<PAGE>


ongoing assessment of the recoverability of these costs requires considerable
judgment by management with respect to certain external factors, including, but
not limited to, anticipated future gross product revenue or royalties, estimated
economic life and changes in software and hardware technology. The Company
amortizes software development costs based on projected revenue, with minimum
annual amortization based on a seven-year life using the straight-line method.

EARNINGS PER COMMON SHARE
The Company follows SFAS No. 128, EARNINGS PER SHARE. This Statement replaces
previously reported primary and fully diluted earnings per share with basic
and diluted earnings per share. Unlike primary EPS, basic EPS excludes any 
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to previously reported fully diluted earnings
per share.

NOTE 2

CREDIT FACILITY
The Company has a credit agreement that provides up to $500,000 in short-term
borrowings at 1.25% over the prime rate (9.00% at December 31, 1998). The
agreement limits the amount of short-term borrowings to 65% of eligible
receivables. Substantially all assets are pledged as collateral on the
borrowings. The credit agreement further includes covenants which relate to
certain financial statement ratios and restrictions. The Company had no
outstanding borrowings in 1998 or 1997.

and non-incentive (NSO) stock options, stock appreciation rights, restricted
stock awards and performance awards to officers, directors, employees,
consultants and independent contractors of the Company and its subsidiaries. In
addition, in 1998 the Board authorized and granted an additional 100,000 shares
under the 1995 Plan subject to shareholder approval and granted options outside
of the 1995 Plan (the Non-Plan) in 1995, 1997 and 1998. The following table

</TABLE>


    Exercise prices for options as of December 31, 1998 ranged from $2.875 to
$4.75. Options under the 1995 Plan and Non-Plan expire at various dates through
2008. At December 31, 1998 there were 279,888 options exercisable at a weighted
average exercise price of $4.06. Options outstanding have a weighted average
remaining contractual life of 8.3 years. The weighted average fair value of
options granted during 1998 was $3.12. There were no options granted in 1997.
    Pro forma information regarding net income and net income per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of
Statement 123. The fair value for these options was estimated at the date of
grant using the Black-Scholes option pricing model with the following
weighted-average assumptions: risk-free interest rate of 5.0%; volatility factor
of the expected market price of the Company's common stock of .838 and
weighted-average expected life of the option of ten years.
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options, which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions. Because the Company's employee stock options have
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.
    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information is as follows:

                                                            1998          1997

                              CAUTIONARY STATEMENT

         Image Sensing Systems, Inc. (the Company), or persons acting on behalf
of the Company, or outside reviewers retained by the Company making statements
on behalf of the Company, or underwriters, from time to time make, in writing or
orally, "forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended. When used in conjunction with an identified
forward-looking statement, this Cautionary Statement is for the purpose of
qualifying for the "safe harbor" provisions of such sections and is intended to
be a readily available written document that contains factors which could cause
results to differ materially from such forward-looking statements. These factors
are in addition to any other cautionary statements, written or oral, which may
be made or referred to in connection with any such forward-looking statement.

         The following matters, among others, may have a material adverse effect
on the business, financial condition, liquidity, results of operations or
prospects, financial or otherwise, of the Company. Reference to this Cautionary
Statement in the context of a forward-looking statement or statements shall be
deemed to be a statement that any or more of the following factors may cause
actual results to differ materially from those in such forward-looking statement
or statements:

MARKET ACCEPTANCE OF AUTOSCOPE SYSTEM. The success of the Company is dependent
upon increasing acceptance of its Autoscope system vehicle detection system in
the markets in which that product is sold. The application of machine vision
technology to traffic management is a relatively new concept in the traffic
management industry. A substantial portion of the Company's revenues to date has
been from royalties from sales of the Autoscope system for deployment in
conjunction with federally funded ITS programs or for evaluation purposes. The
Company's future results of operations and immediate prospects for future growth
will depend in large part on the continued development of the market for
advanced technology solutions for traffic management and the acceptance of the
Autoscope system as a reliable, cost-effective alternative to traditional
vehicle detection systems. There is no assurance that the Autoscope system will
gain sufficient market acceptance to enable the Company to sustain profitable
operations.

DEPENDENCE ON THIRD PARTIES FOR MANUFACTURING AND MARKETING. The Company does
not have and does not in the near future intend to develop the capability to
manufacture its products. Pursuant to the Econolite Agreement, the Company
appointed Econolite as its licensee to manufacture, distribute and sell the
Autoscope system and related technology on an exclusive basis in North America
and the Caribbean. Pursuant to the Cohu Production Agreement, the Company
appointed Cohu to manufacture the Autoscope Solo product. The Company believes
that alternative manufacturing sources could be obtained, if necessary, but the
inability to obtain alternative sources, if and as required in the future, could
result in delays or reductions in product shipments which in turn may have an
adverse effect on the Company's operating results. In addition, Econolite has
the exclusive right to market the Autoscope system and related products in North
America



                                       1

<PAGE>


and the Caribbean. Consequently, the Company's revenues depend to a significant
extent on the marketing efforts of Econolite. The inability of Econolite to
adequately manufacture or effectively market the Autoscope system, or the
disruption or termination of that relationship could have a material adverse
effect on the Company's operations.

DEPENDENCE ON PRIMARY DISTRIBUTOR. Pursuant to the Econolite Agreement,
Econolite pays a royalty to the Company for sales of Autoscope systems. Since
1991, over sixty percent of the Company's revenue has been from royalties
resulting from sales made by the Company's primary distributor, Econolite.
Although Econolite has consistently made payments to the Company when due and
although the Company has no reason to believe that Econolite will not continue
to do so in the future, there can be no assurance that Econolite will continue
to make such payments in a timely manner, whether due to financial insolvency,
liquidity problems or other reasons. The inability of Econolite to make such
payments could have a material adverse effect on the Company's financial
condition and operations.

DEPENDENCE ON ONE PRODUCT. Over eighty percent of the Company's revenues since
inception have been generated from sales of, or royalties from the sale of, the
Autoscope system. The Autoscope system is currently the Company's only product
sold commercially. The Company expects the Autoscope system to gain greater
market acceptance and the number of applications for the system to increase.
There can be no assurance, however, that a significant sustainable market will
develop for the Autoscope system or that the Company will be able to profitably
utilize its technology in other products or markets.

DEPENDENCE ON SALES TO GOVERNMENTAL ENTITIES; PERIODIC FLUCTUATIONS IN SALES.
Sales of the Autoscope system are made primarily to governmental entities.
Purchase decisions by governmental entities often take considerable time, and
there can be no assurance that, notwithstanding the marketing efforts by the
Company or Econolite, such purchase decisions will not be substantially delayed
and adversely affect the Company's business operations. Until broader market
acceptance of the Autoscope system is achieved, revenues and royalties from
sales of the Autoscope system will come substantially from sales to governmental
entities for use in large traffic control projects using advanced traffic
control technologies. It often takes considerable time before these projects are
developed to the point where an actual purchase of the Autoscope system is made.
Once a governmental entity decides to purchase the Autoscope system, however, it
will often purchase a significant number. Consequently, the Company's revenues
and income may fluctuate significantly between fiscal periods. Moreover, there
can be no assurance that, once market acceptance of the Company's technology is
obtained, governmental budgetary constraints in the U.S. and elsewhere will not
delay or decrease purchases of the Company's product by such entities.

PATENTS AND PROPRIETARY RIGHTS. The Company's success depends in part on its
ability to maintain its proprietary rights in the technology underlying the
Autoscope system. The Company relies on a combination of trade secrets,
copyrights and patents to protect its proprietary rights in the system. The U.S.
and foreign patents for certain aspects of the underlying technology for the
Autoscope system are owned by the University of 



                                       2

Minnesota. The Company has entered into a license agreement with the University
of Minnesota, pursuant to which the Company has been granted an exclusive,
worldwide license, with a right to grant sub-licenses, to make, have made, use,
sell and lease products incorporating such technology, and the Company pays the
University a royalty for the license. The University of Minnesota may terminate
the license only in limited circumstances. Nevertheless, termination of the
license agreement with the University of Minnesota for whatever reason, could
have a material adverse effect on the Company's operations. The Company has not
applied for patent protection in all foreign countries in which it may market
and sell the Autoscope system. Consequently, the Company's proprietary rights in
the technology underlying the Autoscope system will be protected only to the
extent that trade secret, copyright or other non-patent protection is available
in such countries and to the extent the Company is able to enforce such rights.
No assurance can be given that the scope of current or any future patents
relating to the Company's product will exclude competitors or provide
competitive advantages to the Company or that the current patent on the
technology underlying the Autoscope system will be held valid if subsequently
challenged. There can be no assurance that others have not developed or will not
develop similar products, duplicate any of the Company's products or design
around such patents. Litigation, which could result in substantial cost to and
diversion of effort by the Company, may be necessary to enforce patents related
to the Company's products, to defend the Company against claimed infringement of
the rights of others or to determine the ownership, scope or validity of the
proprietary rights of the Company and others. The Company also relies on trade
secrets to protect technology not covered by patent. The Company has entered
into confidentiality agreements with its employees, consultants and others,
however, there can be no assurance that confidentiality obligations will be
honored or that the Company's trade secrets will not otherwise become known or
independently developed by competitors.

TECHNOLOGICAL RISK. The Company believes that the Autoscope system is the most
advanced and adaptive technology commercially available for vehicle detection,
and the market served by the Company is increasingly seeking advanced
technological solutions to traffic management and control problems.
Consequently, competitive product developments, introductions and enhancements
are increasing. There can be no assurance that developments by current or future
competitors of the Company will not render the Company's products or
technologies noncompetitive or obsolete.

MANAGEMENT OF GROWTH. The Company intends to increase its Asian operations and
intensify its marketing efforts and distribution arrangements in Asia through
its sixty-percent owned affiliate. If the Company's increased marketing efforts
are successful and its expansion occurs, the Company may experience a period of
significant growth. This growth and expansion could place a significant strain
on the Company's resources, including working capital resources, and result in
an increase in the level of responsibility of the Company's management
personnel. The Company's ability to manage its growth effectively will require
it to continue to improve its operational, financial and management systems, and
to successfully train, motivate and manage its employees. If the Company's
management is unable to manage its growth effectively, the Company's 




                                       3

results of operations could be materially adversely affected. While the Company
believes that it can manage such growth, there can be no assurances that it will
be able to do so.

CONTROL BY EXISTING SHAREHOLDERS. As of December 31, 1998, directors and
executive officers of the Company owned beneficially approximately 54.5% of the
Company's outstanding Common Stock. Accordingly, these shareholders may be able
to influence the outcome of shareholder votes, including votes concerning the
election of directors and the outcome of corporate actions requiring shareholder
approval, such as mergers and acquisitions, regardless of how other shareholders
of the Company may vote. This concentration of voting control may have a
significant effect in delaying, deferring or preventing a change in management
or change in control of the Company and may adversely affect the voting or other
rights of other holders of Common Stock.

YEAR 2000 ISSUE. Many currently installed computer systems and software are
coded to accept only two-digit entries in the date code fields. These date code
fields will need to accept four-digit entries to distinguish 21st century dates
from 20th century dates. This problem could result in system failures or
miscalculations causing disruptions of business operations (including, among
other things, a temporary inability to process transactions, send invoices or
engage in other similar business activities). As a result, many companies'
computer systems and software will need to be upgraded or replaced in order to
comply with year 2000 requirements. The potential global impact of the year 2000
problem is not known, and, if not corrected in a timely manner, could affect the
Company and the U.S. and world economies generally.

                  Based on assessments to date, the Company believes it will not
experience any material disruption as a result of year 2000 problems with
respect to its products and the third-party systems the Company uses for its
internal functions, and, in any event, the Company does not anticipate the year
2000 issues it will encounter will be significantly different than those
encountered by other computer hardware and software manufacturers, including our
competitors. For example, if certain critical third-party providers, such as
those providers supplying electricity, water or telephone service, experience
difficulties resulting in disruption of service to the Company, a shutdown of
the Company's operations could occur for the duration of the disruption.
Assuming no major disruption in service from utility companies or other critical
third-party providers, the Company believes that it will be able to manage its
year 2000 transition without any material effect on the Company's results of
operations or financial condition.
