                         SAFE HARBOR STATEMENT UNDER THE
                PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

            This Quarterly Report on Form 10-QSB contains 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.
These forward-looking statements involve risks and uncertainties that may cause
the Company's actual results to differ materially from the results discussed in
the forward-looking statements. Factors that might cause such differences
include, but are not limited to, lack of market acceptance of the Company's
products; dependence on third parties for manufacturing and marketing
capabilities and continuing ability to pay royalties owed; inability of the

                                       2



Company to diversify its product offerings; revenue fluctuations caused by the
Company's dependence on sales to governmental entities; failure of the Company
to secure adequate protection for the Company's intellectual property rights;
failure of the Company to respond to evolving industry standards and
technological changes; inability of the Company to properly manage growth in
revenue and/or production requirements; inability of the Company to meet its
future additional capital requirements; and control of the voting stock by
insiders. The forward-looking statements are qualified in their entirety by the
cautions and risk factors set forth in Exhibit 99, under the caption "Cautionary
Statement," to this Quarterly Report.

Item 2.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

            (Three- and Nine-month Periods Ended September 30, 1999)


Revenue for the third quarter of 1999 was $895,000, an increase of 32% from
$677,000 for the same period a year ago, while revenue for the nine-month period
ended September 30, 1999 was $3,182,000, an increase of 43% from $2,224,000 a
year ago. The increase in revenue from product sales and royalties for these
periods was due primarily to more sales of Autoscope(R) systems by both Image
Sensing Systems, Inc. (ISS) and its North American distributor, Econolite
Control Products, Inc. (Econolite). Unit sales by ISS and Econolite increased
88% for the third quarter and have increased 63% for the nine-month period ended
September 30, 1999, compared to the same periods a year ago. Revenue from direct
sales and royalties for the third quarter of 1999 increased 21% and 77%,
respectively, compared to the third quarter of 1998. Revenue from direct sales
and royalties for the nine-month period ended September 30, 1999 increased 42%
and 52%, respectively, compared to a year ago.

Gross profit was $661,000 in the third quarter of 1999, or 74% of revenue,
compared to $516,000, or 76% of revenue, for the same period a year ago. Gross
profit for the nine-month period ended September 30, 1999 was $2,371,000, or 75%
of revenue, compared to $1,666,000, or 75% of revenue, for the same period a
year ago.

Selling, general and administrative expenses were $751,000 and $2,117,000,
respectively, for the three- and nine-month periods ended September 30, 1999,
compared to $522,000 and $1,680,000, respectively, for the same periods a year
ago. The increases were due primarily to added efforts in business development
and amortization of software development costs which began in October 1998.

Research and development expenses were $174,000 and $543,000, respectively, for
the three- and nine-month periods ended September 30, 1999, compared to none for
the same periods a year ago. The increase resulted because all development
efforts in the first nine months of 1998 were directed toward software
development for the new Autoscope Solo product with associated costs capitalized
in accordance with Statement of Financial Accounting Standards No. 86.

Loss from operations was $264,000 and $289,000, respectively, for the three- and
nine-month periods ended September 30, 1999, compared to $6,000 and $14,000 for
the same periods a year ago. The increase in operating losses was due primarily
to research and development costs incurred in 1999 compared to 1998 and an
increase in business development expense in 1999.

                                       8



Other income, net, was $17,000 and $57,000, respectively, for the three- and
nine-month periods ended September 30, 1999, compared to $23,000 and $78,000,
respectively, for the same periods a year ago. The decrease resulted primarily
from holding less cash in interest bearing cash equivalents during the first
nine months of 1999.

The Company does not expect to receive any current income tax benefit from
losses incurred in 1999.

Liquidity and Capital Resources:

Cash provided by operating activities was $133,000 for the nine-month period
ended September 30, 1999, compared to $313,000 for the same period in 1998. The
reduced cash flow from operations in the nine-month period ended September 30,
1999 was primarily due to an unusually large collection on accounts receivable
in 1998 compared to 1999.

Capital expenditures were $78,000 for the nine-month period ended September 30,
1999, which is comparable to 1998. The Company does not expect to make
significant changes to the level of investments in capital expenditures for the
balance of 1999. The Company is no longer incurring software development costs
that should be capitalized, whereas $825,000 in such costs were incurred in the
nine-month period ended September 30 1998.

Management believes that its cash and investment position, anticipated cash
flows from operations, and funds available through its bank line of credit will
be sufficient to meet working capital requirements for current operations and
planned new product introductions for the foreseeable future.

Impact of the Year 2000 Issue

The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Some computer programs
that have date-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. All of the software produced by the Company has
been analyzed and the Company is not aware of any potential for date recognition
problems in its products. However, the Company also uses off-the-shelf software
produced by third parties for use in administrative functions such as word
processing, network administration, voice mail messaging, billing and record
keeping. In the event, that any of such programs are susceptible to date
recognition problems, this could result in a system failure or miscalculations
causing disruption of operations, including, among other things, intra-company
communications, preparation of invoices and collection of accounts receivables,
and many other normal business activities.

The Company has made every attempt to identify all relevant software that may
affect the Company's operations through surveys and examination. Based on risk
assessments that

                                       9



have been completed for the majority of the Company's operations, the Company
converted the majority of its business operations to new Year 2000 compatible
software by a combination of conversion to new software and upgrading existing
software. The cost of these conversions to date has not been material. However,
there can be no guarantee that a failure to convert by another company, or a
conversion that is incompatible with the Company's systems, would not have a
material adverse effect on the Company.
