ITEM 1. BUSINESS

        A glossary of selected technical terms is included at the end of this
section. Please review the glossary before reading the description of business.
International Remote Imaging Systems, Inc. and its subsidiaries are sometimes
referred to as IRIS, the Company, we, our or us.

INTRODUCTION

        In March of 2000, we entered into a letter of intent to sell
Perceptive Scientific Instruments, our genetic analysis business. In light of
our plans to sell Perceptive Scientific Instruments, we are treating this
business as a discontinued operation for accounting purposes, and we have
removed it from most of the discussion and financial information in this Annual
Report. For a further discussion of our plans to sell this business, please see
the section entitled "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Discontinued Business Operations" beginning
on p. 17.

OVERVIEW

        We design, develop, manufacture and market in vitro diagnostic, or IVD,
imaging systems for urinalysis testing based on patented and proprietary
automated intelligent microscopy, or AIM, technology for automating microscopic
procedures performed in clinical laboratories, as well as special purpose
centrifuges and other small instruments. Our microscopy technology combines our
capabilities in automated specimen presentation, including our patented
slideless microscope, and proprietary high-speed digital processing hardware and
software to classify and present images of microscopic particles in easy-to-view
displays. Our systems provide customers with better and more rapid results and
labor cost-savings over manual methods of performing microscopy. We sell our
products directly and through distributors to hospital and reference clinical
laboratories, as well as to veterinary, physician office and research
laboratories.

        We pioneered our first urinalysis system in 1983 when we introduced The
Yellow IRIS family of workstations and we introduced our fourth generation
models, which are faster and easier to use, in 1996. We believe that we are
still the only supplier of laboratory systems which fully automate a complete
urinalysis. Also in 1996, we began to market the Model 900UDx urine pathology
system, which was designed especially for the high-volume testing requirements
of larger laboratories. We also provide ongoing sales of supplies and service
for The Yellow IRIS workstations. Most supplies are purchased under standing
orders and, following an initial one-year warranty period, the majority of
customers purchase annual service contracts.

        Through our subsidiary StatSpin, Inc., we manufacture and market a
variety of benchtop centrifuges, small instruments and supplies for the
laboratory market. These products are used primarily for manual specimen
preparation and dedicated applications in cytology, hematology and urinalysis.
They appeal to laboratories and physician offices performing too few tests to
justify the cost of an automated IVD imaging system.

        In December 1997, we began distributing the IRIS/Sysmex UF-100 urine
cell analyzer in the United States under an exclusive agreement with its
manufacturer, Sysmex Corporation. We did not have significant sales of the
UF-100 in 1998 or 1999. In September 1998, Sysmex started procedures
to end the exclusive nature of our distribution rights, claiming inadequate
sales performance. We denied these allegations. Sysmex now claims that it has
the right to appoint additional distributors and has announced that its U. S.
subsidiary will distribute the UF-100 in North America. We dispute that Sysmex
has this right and may take legal action. We cannot predict the impact on the
Company of the announcement by Sysmex or any legal action we may take.

        We acquired Perceptive Scientific Instruments in July 1996. Its
principal product is the PowerGene family of genetic analyzers -- IVD imaging
systems for karyotyping, DNA probe analysis and comparative genomic
hybridization. In March of 2000, we entered into a letter of intent to sell
this business to a well-known international company for an estimated price of
$2.5 to $5.0 million in cash. For a further discussion of our plans to sell this
business, please see the section entitled "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Discontinued Business
Operations" beginning on p. 17.

THE INDUSTRY

        The healthcare industry has undergone profound changes in the last
decade, and healthcare providers are continually focusing on the most efficient
use of their resources. This goal drives them to reduce costs while
simultaneously improving the outcome potential of patient care. Toward that end,
they must reduce the cost and improve the accuracy of medical tests for
diagnosing and monitoring diseases and improve the reporting of test results.

        Medical tests are performed either on the patient or on a specimen
removed from the patient. IVD testing refers to analysis of a specimen removed
from the patient, usually in the clinical laboratory. Many IVD tests rely on
chemical or simple physical measures of specific characteristics of the
specimen. Over the last five decades, the chemical and particle-counting aspects
of these tests have been largely converted from manual methods to automated
instruments, such as clinical chemistry analyzers and blood cell counters.
However, many other IVD tests still require visual examination of the specimen
through a microscope ("microscopy"). Manual microscopy requires numerous steps,
from specimen preparation to visual examination, making the method
labor-intensive, cumbersome, biohazardous, inefficient and imprecise. More time
is spent in performing manual microscopy than in any other IVD testing procedure
in the clinical laboratory. Even so, the vast majority of microscopic procedures
are still performed manually.

        The pressure to reduce the costs and improve the accuracy of IVD tests,
together with recent technological developments, have created an opportunity for
automating microscopic procedures. Advances in image processing software,
computer hardware and solid-state cameras have made it possible to uniformly
capture digital images of microscopic specimens and to perform sophisticated
image analysis and classification. The test results can then be electronically
transmitted to the central computer system of the hospital or reference
laboratory for clinical use and billing. The digital images of the specimen can
also be stored in electronic format for future review and, theoretically,
transmitted to remote locations for review by other technologists or
specialists.

THE COMPANY'S STRATEGY

        Our current objectives are to enhance our core business in urinalysis,
maintain our technological leadership, continue market penetration of our
existing products, expand the geographic markets for existing products and
increase sales of related supplies and service. We are pursuing these objectives
through the following strategies:

        -       Enhancement of Existing Product and Continued Market
                Penetration. In 1999, we reassessed our business and developed a
                new two-year business plan. The plan refocuses our efforts on
                our core urinalysis business. The plan emphasizes making major
                improvements to The Yellow IRIS urinalysis workstation product
                line.  Our goal is to develop a lower cost, faster workstation
                while simultaneously reducing the amount of technologist time
                required to operate it.

        -       Expanding into New Geographic Markets. We intend to continue to
                increase our overseas marketing effort initiated in 1999. Until
                1999, we had not made significant international sales of the
                Yellow IRIS outside the United States. International markets
                have recently begun to consolidate and focus on increased
                productivity. We are introducing The Yellow IRIS in selected
                overseas markets where consolidation has already occurred and
                are developing relationships with local distributors.

        -       Increasing Sales of Supplies and Service. Once The Yellow IRIS
                workstation is installed, we generate significant recurring
                revenue from sales of supplies and service for its operation. We
                will try to increase these revenues by installing more systems
                and by increasing our product offering of supplies for this
                system.

        -       Maintaining Technological Edge. We maintain an active research
                and development program to continually enhance our core
                technology.

AIM TECHNOLOGY

        An effective system for most automated microscopy applications requires
technology for fast, consistent and easily discernable presentation of the
specimen to the microscope ("front end processing") and for rapidly capturing,
analyzing, classifying, enhancing, arranging and displaying images of the
specimen ("back end



                                       2
<PAGE>   5

imaging"). Over the past twenty years, we have created and developed our
patented and proprietary AIM technology to address both of these requirements.

        Our AIM technology automates all or most of the front end processing in
its IVD imaging systems. For example, traditional urine sediment analysis
requires manual preparation of a slide from the specimen requiring several
steps, including centrifugation followed by carefully positioning, staining and
coverslipping a sample extracted from the specimen. The slide is then placed
under the microscope and manually manipulated and scanned by a technologist.
This procedure is time-consuming, imprecise, and potentially hazardous. In
contrast, our patented slideless microscope, used in The Yellow IRIS, allows
microscopic examination of a moving specimen precisely positioned in a stream of
fluid. This eliminates the need for manual slide preparation, manipulation and
scanning. The slideless microscope positions the specimen to within microns as
it flows past the microscope at high-speed ensheathed in a larger stream of
fluid. This method of alignment, particle orientation, focus and measurement is
called "imaging flow cytometry." We hold a patent on this method, and we are
unaware of any other company which has developed similar technology. For those
IVD tests where imaging flow cytometry does not work well, AIM technology
automates the slide manipulation and scanning process.

        Once the specimen is located and presented to the microscope, AIM's back
end imaging automatically captures, digitizes, classifies, organizes and
presents the microscopic images displayed on a video monitor for review by the
medical specialist. These digital images of the specimen can then be stored on
magnetic or optical media for later retrieval, even years later.

PRODUCTS

        Urinalysis Systems

        Our principal product is The Yellow IRIS family of urinalysis
workstations. This system requires customers to make substantial capital
investments and is designed for sale to clinical laboratories performing a large
number of IVD tests. The Yellow IRIS is used nationwide, including hospitals
affiliated with over 75% of all United States medical schools. This family of
IVD imaging systems consists of three models. Two models can also perform IVD
imaging tests on a number of body fluids other than urine, including
cerebrospinal, peritoneal, pleural, pericardial, synovial and seminal fluids as
well as peritoneal dialyzates and lavages. The third model, the Model 900UDx, is
designed for laboratories testing high numbers of urine specimens. The Yellow
IRIS family of IVD imaging systems currently has list prices ranging from
$100,000 to $195,000.

        In the fourth quarter of 1997, we began marketing the IRIS/Sysmex UF-100
urine cell analyzer in the United States. The UF-100, developed in Japan by
Sysmex Corporation, utilizes flow cytometric laser scanning principles to screen
large volumes of urine specimens for the presence of abnormal sediment
compositions. We are the exclusive distributor for the UF-100 in North America
and receive royalties from Sysmex on sales of the UF-100 outside of North
America. The UF-100 currently has a list price in the United States of $125,000.
It provides only the sediment portion of a complete urinalysis.

        In September 1998, Sysmex started procedures to end the exclusive nature
of our distribution rights, claiming inadequate sales performance. We disputed
these allegations and began discussions with Sysmex about the pricing and
marketing of the UF-100. Those discussions did not resolve the matter. Sysmex
has asserted the right to appoint additional distributors and has announced that
its U.S. subsidiary will distribute the UF-100 in North America. We dispute that
Sysmex has this right and may take legal action. We cannot predict the impact of
Sysmex's announcement or any legal action we may take.  We did not have
significant sales of the UF-100 in 1998 or 1999.

        System Supplies and Service

        We realize significant recurring revenue from sales of supplies used in
the operation of The Yellow IRIS and from their service and repair. These
supplies include the sheath fluid used to position the particles and cleanse the
system in slideless microscopy and "controls" used in calibrating and monitoring
the performance quality of the systems. We also sell the CHEMSTRIP/IRIStrip for
testing urine chemistry on The Yellow IRIS. CHEMSTRIP/IRIStrips urine test
strips are produced for us through an agreement with Roche Diagnostics.

        Small Instruments and Supplies

        We also manufacture and market a variety of small instruments and
supplies for the clinical laboratory market through our StatSpin subsidiary.
These products complement our line of urinalysis systems because they appeal



                                       3
<PAGE>   6

to smaller laboratories and physician offices that do not perform enough tests
to justify the capital cost of a large automated system. StatSpin's
technologically-advanced small benchtop centrifuges prepare certain biological
specimens for instrumental or microscopic examination in a fraction of the time
required by larger, common laboratory centrifuges. They have proven ideal for
on-demand, point-of-use testing in hospitals, physician's offices and veterinary
laboratories. The basic StatSpin centrifuge unit is adaptable to a variety of
uses through application-specific rotors and consumables. Noted for their
compact design and simple, quiet, and unobtrusive operation, they are
well-suited to laboratories in which technicians are located close to the
equipment. These products also serve integrated healthcare providers who want to
purchase systems and supplies for a variety of clinical settings (both large and
small) from one supplier. This category of products includes special-purpose
centrifuges, digital refractometers for measuring the specific gravity of urine,
the CenSlide System for manual microscopic examination of urine and other
supplies intended primarily for specimen preparation.

BACKLOG

        We had a sales backlog for our urinalysis systems of $221,000 at
December 31, 1998 and $341,000 at December 31, 1999. We believe the amount of
backlog at a given date is not necessarily indicative of sales for any
succeeding period.

RESEARCH AND DEVELOPMENT

        We maintain an active research and development program to continually
enhance our urinalysis systems and centrifuges. Our product technology
investments (including amounts reimbursed by third parties under research



                                       4
<PAGE>   7

and development contracts) totaled $2.5 million in 1997, $2.2 million in 1998
and $1.4 million in 1999. During 1997 and 1998, we upgraded the installed base
of Model 900UDx systems to increase reliability and enhance overall performance.
During 1998, we completed work on software updates to make The Yellow IRIS
family of workstations Y2K compliant. We also continued to refine our AIM
technology, improve the cost-effectiveness of our systems and conduct numerous
other smaller projects during those years.

        During 1999, we began a major project to improve The Yellow IRIS
urinalysis workstation product line.  We plan to devote most of our research
and development budget to this project.  Our goal is to develop a lower cost,
faster workstation while simultaneously reducing the amount of technologist time
required to operate it.  During this process, we will incorporate more than 20
years of experience and the latest developments in computer technology.  We
also expect to benefit from the increased availability of "off-the-shelf"
components and thereby reduce our dependence on single source suppliers.

        We have completed feasibility studies on the proposed improvements.  We
believe that this project is important to maintaining our competitive position
in the urinalysis market and that our failure to successfully complete this
project on schedule could have a material and adverse effect on future system
sales.

        We have historically received partial funding for research and
development programs through grants from NASA and the National Institutes of
Health, joint development programs with strategic partners, and
Company-sponsored research and development entities. From 1994 to 1996, we
collaborated with Boehringer Mannheim Corporation and Boehringer Mannheim GmbH,
entities subsequently acquired by Roche Diagnostics, in the development of
CHEMSTRIP/IRIStrip urine test strips and the Model 900UDx. Roche is the sole
supplier of CHEMSTRIP/IRIStrip urine test strips and has agreed to supply us
with certain raw materials should we elect to manufacture our own urine test
strips, subject to royalty payments. We were also granted the non-exclusive
right to distribute certain other Roche urinalysis products to hospitals and
commercial laboratories in the United States. We manufacture the Model 900UDx
with Roche providing certain components on an OEM basis at cost. We have
exclusive marketing rights to the Model 900UDx in the United States, Canada and
Taiwan, and non-exclusive rights for the rest of the world outside of Germany
and Italy.

        In 1992, we entered into a project with LDA Systems, Inc. for
development of The White IRIS leukocyte differential analyzer and later acquired
LDA for approximately 498,000 shares of our common stock. In 1999, we conducted
a reassessment of our business and developed a new, near-term business plan. We
elected not to include The White IRIS in our new plan, and, as a result, we
wrote off all costs of development and inventory related to The White IRIS in
the third quarter of 1999.

        In 1995, we entered into a project with Poly U/A Systems, Inc. for
development of several new products to enhance automated urinalysis.
Subsequently, certain disputes arose with the Poly U/A shareholders. In 1999, we
made a tender offer to acquire all of the outstanding shares of Poly U/A stock
for a package of IRIS securities with an estimated value of up to $1.5 million.
Approximately 79% of the outstanding shares of Poly U/A were tendered in this
transaction. We have recorded the cost of purchasing the Poly U/A stock as a
litigation settlement expense. Poly U/A is now a majority-owned subsidiary of
IRIS, and is accounted for accordingly.

MARKETING AND SALES

        In the United States, we sell and service our products through our own
sales and service forces. Sales activities consist of direct sales by field
sales representatives, telemarketing to initiate and aid in pursuing sales
opportunities, logistics support of the field sales representatives and
after-sales support to customers in the operation of their systems. In addition
to our sales activities, we promote our products through advertising in trade
journals, attendance at trade shows and direct mail. All sales of IVD imaging
systems include installation, customer training and a one-year warranty. Our
small instruments, targeted primarily at smaller customers, are sold through
distributors.



                                       5
<PAGE>   8

        We also maintain a rental program for The Yellow IRIS urinalysis
workstation. Under the terms of the rental agreements, payments generally are
based on the number of tests performed, with a guaranteed monthly minimum
payment. We are responsible for supply and service of the systems.
Alternatively, some customers lease the our systems from medical equipment
leasing companies which, in turn, purchase the systems from us.

        In addition, we market most of the supplies used in the operation of The
Yellow IRIS and maintain these systems through our own national service
organization. Service (after a one-year warranty period) is generally sold under
an annual service contract or, less frequently, on a per-call basis.

COMPETITION

        Our primary products are The Yellow IRIS family of urinalysis
workstations and the UF-100 urine cell analyzer. The principal competitive
factors in the urinalysis market are cost-per-test, ease of use, and quality of
result. We believe these products compete favorably with regard to these factors
in their respective target markets.

        A number of hospitals conduct urine sediment examinations using the Kova
system made by Hycor Biomedical, Inc., as well as several other similar
products, all of which are composed largely of disposable plastic parts. These
products provide a more standardized method of preparing urine sediment for
microscopical examination as opposed to traditional means. While these
disposable products help somewhat to overcome manipulative imprecision, most of
them do so at the added expense of an increased number of disposable parts and
offer little in time savings. One exception is the CenSlide System, which we
acquired in March 1996. This system uses a combination centrifuge tube and
microscope slide, thereby actually eliminating much of the manipulation required
in preparing the urine specimen for microscopic observation. These types of
products are better suited for laboratories performing a small number of
urinalysis tests.

        Bayer Diagnostics, Roche Diagnostics, and Dade Behring Corporation sell
lines of urine test strips which are useful in determining the concentration of
various chemical substances often found in urine. Some claims have been made
that the absence of certain results determined with these test strips can
preclude the need for microscopic examinations of some specimens. In 1998, we
obtained FDA clearance to claim of improved performance of The Yellow IRIS over
reagent strip measures in detecting microscopic abnormalities in urine.
Nonetheless, a substantial portion of the urinalysis market has subscribed to
the theory that these test strips can be relied upon to reduce the number of
microscopic examinations. We believe that this is largely due to laboratories'
reacting to cost-cutting pressures. The result is significantly slower growth in
the demand for microscopic examinations at certain hospitals and reference
laboratories.

        The Yellow IRIS currently supports only automated test strip readers
supplied by Roche Diagnostics, and some potential customers who have previously
purchased automated test strip readers from Bayer Diagnostics (the dominant
company in the urine test strip business) cannot connect those readers to The
Yellow IRIS. Our ability to modify The Yellow IRIS to support a connection to
test strip readers from Bayer Diagnostics and Dade Behring is subject to
significant restrictions under our existing agreements with Roche Diagnostics.

        We are also experiencing increased competitive pressures in the
urinalysis market due to the ongoing consolidation of both hospitals and medical
device suppliers. Large hospital chains and groups of affiliated hospitals are
negotiating comprehensive supply contracts with the larger medical device
suppliers. The larger suppliers often equip an entire laboratory and offer
one-stop shopping for laboratory instruments, supplies and service. In addition,
they typically offer the hospitals annual rebates based on the total volume of
business with the suppliers. These rebates create financial incentives against
purchasing instruments or supplies from others and act as a barrier to the
penetration of hospital laboratories covered by the contract. For example, we
have had significant difficulty in marketing our urinalysis products to
hospitals which are members of Premier Enterprises, a nationwide buying
cooperative of hospitals and healthcare systems. Premier generally establishes a
single vendor for particular product lines and has designated Bayer Diagnostics
as its vendor for urinalysis test strips. Our family of urinalysis workstations,
The Yellow IRIS, uses test strips manufactured for us by Roche Diagnostics and
many Premier affiliated hospitals are reluctant to purchase The Yellow IRIS for
this reason.

INTELLECTUAL PROPERTY

        Our commercial success depends on our ability to protect and maintain
our proprietary rights. We protect our proprietary technology by filing various
patent applications. We have received numerous United States patents for its AIM
technology and related applications, as well as a number of corresponding
foreign patents. These patents also cover developments in image analysis and
blood processing. A number of additional patent applications are pending in the
United States and abroad. These patents also cover image analysis, urine and
blood processing. Also, numerous patents relating to digital refractometers,
centrifuges, automated slide handling and disposable urinalysis products were
acquired in various acquisitions.

        We have granted Sysmex a royalty-bearing license to use pre-1989
technology for urine sediment analyzers and non-medical industrial instruments.
We have also granted Dade International a royalty-bearing license to use certain
centrifuge technology.

        We have trade secrets and unpatented technology and proprietary
knowledge about the sale, promotion, operation, development and manufacturing of
our products. We have confidentiality agreements with our employees and
consultants to protect these rights.

        We claim copyright in our software and the ways in which it assembles
and displays images, and have filed copyright registrations with the United
States Copyright Office. We also own various federally registered trademarks,
including "IRIS," "The Yellow IRIS" and "StatSpin." We own numerous other
registered and unregistered trademarks, and have certain trademark rights in
foreign jurisdictions. We intend to aggressively protect our copyrights and
trademarks.

GOVERNMENT REGULATIONS

        Most of the our products are subject to stringent government regulation
in the United States and other countries. These laws and regulations govern
product testing, manufacture, labeling, storage, record-keeping, distribution,
sale, marketing, advertising and promotion. The regulatory process can be
lengthy, expensive and uncertain, and securing clearances or approvals often
requires the submission of extensive official data and other supporting
information. If we don't comply with regulatory requirements, we may be subject
to fines, recall or seizure of products, total or partial suspension of
production, withdrawal of existing product approvals or clearances, refusal to
approve or clear new applications or notices and criminal prosecution. Further,
any change in existing federal, state or foreign laws or regulations, or in
their interpretation or enforcement, or the enactment of any additional laws or
regulations, could affect us both materially and adversely.

        In the United States, the FDA regulates medical devices under the Food,
Drug, and Cosmetic Act (the "FDC Act"). Before a new medical device can be
commercially introduced in the United States, the manufacturer usually must
obtain FDA clearance by filing a pre-market notification under Section 510(k) of
the FDC Act (a "510(k) Notification") or obtain FDA approval by filing a
pre-market approval application (a "PMA Application"). The PMA Application
process is significantly more complex, expensive, time-consuming and uncertain
than the 510(k) Notification process. To date, we have cleared all of our
regulated products with the FDA through the 510(k) Notification process. Of
course, we can't guarantee that we will be able to use the 510(k) Notification
process for future products. Furthermore, FDA clearance of a 510(k) Notification
or approval of a PMA Application is subject to continual review, and the
subsequent discovery of previously unknown facts may result in restrictions on a
product's marketing or withdrawal of the product from the market.

        We are also required to register as a medical device manufacturer with
the FDA and comply with FDA regulations concerning good manufacturing practices
for medical devices ("GMP Standards"). In 1997, the FDA expanded the scope of
the GMP Standards with new regulations requiring medical device manufacturers to
maintain control procedures for the design process, component purchases and
instrument servicing. The FDA periodically inspects our manufacturing facilities
for compliance with GMP Standards. We believe that we are in substantial
compliance with the expanded GMP Standards.



                                       7
<PAGE>   10

        The FDA also regulates computer software of the type used in The Yellow
IRIS and is currently reevaluating the regulation of such software. We can't
predict the extent to which the FDA will regulate such software in the future.

        Labeling, advertising and promotional activities for medical devices are
subject to scrutiny by the FDA and, in certain instances, by the Federal Trade
Commission. The FDA also enforces statutory and policy prohibitions against
promoting or marketing medical devices for unapproved uses.

        Many states have also enacted statutory provisions regulating medical
devices. The State of California's requirements in this area, in particular, are
extensive, and require registration with the state and compliance with
regulations similar to the GMP Standards established by the FDA. While the
impact of such laws and regulations has not been significant to date, it is
possible that future developments in this area could affect us both materially
and adversely.

        In addition to domestic regulation of medical devices, many of our
products are subject to regulations in foreign jurisdictions. The requirements
for the sale of medical devices in foreign markets vary widely from country to
country, ranging from simple product registrations to detailed submissions
similar to those required by the FDA. We have not yet applied for regulatory
clearances or approvals to market The Yellow IRIS in most of these foreign
countries. Our business strategy includes expanding the geographic distribution
of these and other products, and we cannot guarantee that we will be able to
secure the necessary clearances and approvals in the relevant foreign
jurisdictions. Furthermore, the regulations in certain foreign jurisdictions
continue to develop and we cannot be sure that new laws or regulations will not
have a material adverse effect on our existing business or future plans. Among
other things, CE Mark certifications are, or may soon be, required for the sale
of many products in certain international markets such as the European
Community. We do not plan to pursue CE Mark certification for The Yellow IRIS
until we have completed our new platform, and this may hinder foreign sales of
The Yellow IRIS in the interim.

        Our products are also subject to regulation by the United States
Department of Commerce export controls, primarily as they relate to the
associated computers and peripherals. We have not experienced any material
difficulties in obtaining necessary export licenses to date.

SEGMENT AND GEOGRAPHIC INFORMATION

        See Note 17 to the Consolidated Financial Statements, "Segment and
Geographic Information," for financial information regarding our operating
segments and geographic areas.

EMPLOYEES

        At December 31, 1999, we had 143 full-time employees, which is
comparable to the number of employees at the end of 1998. Of this number, 39
people were employed by Perceptive Scientific Instruments, a business we plan to
sell. Please see "Management's Discussion and Analysis-Discontinued Business
Operations" on p. 17 for a discussion of these plans. We also use outside
consultants and part-time and temporary employees in production, administration,
marketing and engineering. No employees are covered by collective bargaining
agreements, and we believe that our employee relations are satisfactory.

GLOSSARY OF SELECTED TERMS

        The following glossary defines certain technical terms used to describe
the Company's business.

        AUTOMATED INTELLIGENT MICROSCOPY (AIM). The synthesis of visual
microscopy, digital image processing and automated image interpretation/pattern

<PAGE>   11

in the enhanced image are then automatically separated, matched and aligned into
their respective pairs (karyotype).

        COMPARATIVE GENOMIC HYBRIDIZATION(CGH). A molecular biology method to
globally view DNA for gain or loss (amplifications or deletions) of genetic
material using a FISH procedure.

        CYTOPROBE. A chemical reagent which reacts with enzymatic granules
within a cell to produce unique color characteristics which are useful in
identifying the cell.

        DNA. Deoxyribonucleic acid, the chemical composition of chromosomes in
the nuclei of living cells, consisting of two long chains of alternating
phosphate and deoxyribose units twisted into a double helix and joined by
hydrogen bonds between the complementary bases adenine and thymine or cytosine
and guanine bound in unique sequences that determine genetic characteristics.

        DNA PROBE ANALYSIS. A molecular biology method using synthesized nucleic
acid comprised of unique short sequences of DNA (deoxyribonucleotides) to locate
their exact template along the DNA chain in the nucleus of a cell.

        FLUORESCENT IN-SITU HYBRIDIZATION (FISH). A procedure that allows
microscopic observation of the location of a unique sequence of DNA by using a
DNA probe with a molecule attached to it which emits a distinctive color when
illuminated.

        IN VITRO DIAGNOSTIC (IVD) TESTING. Testing conducted outside of the body
in a laboratory apparatus using a specimen obtained from the patient (blood,
urine, tissue, etc.) to identify or monitor a disease.

        MULTIPLEX FLUORESCENT IN-SITU HYBRIDICATION (M-FISH). A procedure which
utilizes a multiple combination of unique sequence DNA probes and fluorescent

using a patented flowcell through which the specimen literally flows past a
microscope objective.

ITEM 2. PROPERTIES

        We lease all of our facilities. The leases expire at various times over
the next three years. Our headquarters are located at 9162 Eton Avenue,
Chatsworth, California 91311. The table below sets forth certain information
regarding our leaseholds as of December 31, 1999:

</TABLE>

        We believe our facilities are adequate to meet our current needs.
Although we have limited expansion space at our Chatsworth facility, we believe
we can accommodate planned growth at this facility for the near term by leasing
additional office space for certain non-manufacturing related activities, making
modifications to the Chatsworth facility and adding a second shift to our
manufacturing operations.

ITEM 3. LEGAL PROCEEDINGS

        In October 1999, we were awarded $132,500 from the arbitration against
Digital Imaging Technologies, Inc. (DITI), the former owner of our Perceptive
Scientific Instruments genetic analysis business. The arbitration was conducted
under the auspices of the American Arbitration Association. The arbitration
panel found that while certain representations, warranties and covenants in the
purchase agreement for the transaction had been breached by DITI, these breaches
did not damage us significantly. See "Legal Proceedings" in the our Quarterly
Report on Form 10-Q for the quarter ended June 30, 1999 for historical
information on the arbitration.

        We are involved in routine litigation arising in the ordinary course of
our business, and, while we cannot predict the outcome of these proceedings, we
believe they will not materially or adversely affect us.

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

        We did not submit any matters to vote of security holders during the
quarter ended December 31, 1999.

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

INTRODUCTION

        In March of 2000, we entered into a letter of intent to sell
Perceptive Scientific Instruments, our genetic analysis business. In light of
our plans to sell Perceptive Scientific Instruments, we are treating this
business as a discontinued operation for accounting purposes, and we have
removed it from most of the discussion and financial information in this Annual
Report. For a further discussion of our plans to sell this business, please see
the section below on page 17 entitled "Discontinued Business Operations."

OVERVIEW

        We generate revenues primarily from sales of The Yellow IRIS urinalysis
workstation, an IVD imaging system based on our patented and proprietary AIM
technology, and the related supplies and service required to operate this
workstation. We also earn revenues from sales of ancillary lines of small
laboratory instruments and supplies.

        Until 1996, we marketed just two models of The Yellow IRIS urinalysis
workstation. These models differ mainly in speed and price. In 1996, we
introduced a third model of The Yellow IRIS, the Model 900UDx urine pathology
system. This model is a higher capacity automated urinalysis workstation
designed especially for the high-volume testing requirements of large hospitals
and reference laboratories.

        In December 1997, we began distributing the IRIS/Sysmex UF-100 urine
cell analyzer in the United States under an exclusive agreement with its
manufacturer, Sysmex Corporation. We did not have significant sales of the
UF-100 in 1998 or 1999.  In September 1998, Sysmex started procedures to end the
exclusive nature of our distribution rights, claiming inadequate sales
performance. We denied these allegations. Sysmex has announced that its U.S.
subsidiary will distribute the UF-100 in North America. We may take legal
action. We cannot predict the impact on the Company of this announcement or any
legal action we may take.

        Because of the nature of our business, we make significant investments
in research and development for new products and enhancements to existing
products. In the past, we have partially funded our research and development
programs through grants from the National Institutes of Health, joint
development programs with strategic partners and Company-sponsored research and
development entities. We anticipate that future expenditures on research and
development will increase significantly and will be funded entirely out of the
Company's earnings.  See "Business -- Research and Development."

        The following table summarizes total product technology expenditures for
the periods indicated:

        In 1995, we entered into a joint development project with Poly U/A
Systems, Inc. for development of several new products to enhance automated
urinalysis. Subsequently, certain disputes arose with the Poly U/A shareholders.
In 1999, we made a tender offer to acquire all of the outstanding shares of
Poly U/A stock for a package of IRIS securities with an estimated value of up to
$1.5 million. Approximately 79% of the outstanding shares of Poly U/A were
tendered in this transaction. We have recorded the cost of purchasing Poly U/A
stock as a litigation settlement expense. Poly U/A is now a majority-owned
subsidiary of IRIS, and is accounted for accordingly.

RESULTS OF OPERATIONS

        COMPARISON OF YEAR ENDED DECEMBER 31, 1999 TO YEAR ENDED DECEMBER 31,
1998

        Net revenues for the year ended December 31, 1999 increased to $25.7
million from $21.6 million, an increase of $4.1 million, or 19%, over last year.
Sales of IVD imaging systems increased to $6.5 million from $5.0 million, an
increase of $1.5 million, or 30% from the last year. The increase is due
primarily to higher sales to both domestic hospitals and international
distributors. Sales of IVD imaging system supplies and services increased to
$13.6 million from $11.8 million, an increase of $1.8 million or 15% over last
year, primarily due to the larger installed base of The Yellow IRIS IVD imaging
systems. Sales of small instruments and supplies increased to $5.3 million from
$4.3 million, an increase of $952,000, or 22%.

        Revenues from the urinalysis segment totaled $20.4 million in the
current period as compared to $17.0 million last year, an increase of $3.4
million or 20%. This growth is due to increased sales of The Yellow IRIS family
of workstations and increased sales of related system supplies and services to
the growing installed base. Revenues from small laboratory devices segment
increased to $5.3 million in the current period, as compared to $4.6 million
last year, an increase of $717,000. If the non-recurring royalty fee earned from
the prior year is excluded, small laboratory device sales increased $952,000.
This growth is primarily due to increased sales of instruments and consumables
to a larger installed base and one of its distributors.

        Cost of goods for IVD systems as a percentage of sales of IVD imaging
systems totaled 66% in the current period and is comparable to last year. An
increase in proportion of sales of The Yellow IRIS urinalysis workstation to
international distributors with associated lower margins and high costs
associated with the write-off of The White IRIS inventory were offset by lower
costs associated with domestic sales. Cost of goods for IVD imaging system
supplies and services as a percentage of sales of such products decreased to 44%
for the current period as compared to 46% for the same period last year. This
decrease is due to increased revenues while related expenses decreased. Cost of
goods for small instruments and supplies as a percentage of sales of small
instruments and supplies totaled 52% for the current year compared to 55% for
last year due to a change in the sales mix and increased volume. The aggregate
gross margin totaled 49% for the year ended December 31, 1999, and is comparable
to last year's.

        Cost of goods sold as a percentage of revenues from the urinalysis
segment totaled 50%, as compared to 68% last year. This decrease results from
increased urinalysis supplies and services revenues along with lower associated
expenses, partially offset by lower margins on system sales and the write-off of
The White IRIS inventory. Cost of goods for small instrument devices segment as
a percentage of revenues totaled 52% in the current period, and is comparable to
last year. If the nonrecurring royalty fee is excluded, cost of goods sold as a
percentage of sales for this segment declined 3% in 1999.

        Marketing and selling expenses totaled $3.3 million, compared to $3.2
million last year, an increase of $72,000, or 2%, due to increased promotional
activities associated with The Yellow IRIS urinalysis workstation. Marketing and
selling expenses as a percentage of net revenues declined to 13% in 1999 as
compared to 15% last year.

        General and administrative expenses increased to $3.5 million from $2.7
million, an increase of $744,000 or 27% from last year. This increase is
primarily due to higher liability insurance, management incentives and increased
expenses associated with the Office of the Chief Executive and the Board of
Directors. General and administrative expenses as a percentage of net revenues
totaled 13%, and is comparable to last year.

        Net research and development expenses decreased to $1.1 million for the
year ended December 31, 1999, as compared to $1.9 million in 1998. Net research
and development expenses decreased as a percentage of revenues from 9% to 4%.
Reimbursements under joint development programs decreased by $143,000 from the
prior year. Total product technology expenditures, including capitalized
software development costs and reimbursed costs under research and development
grants and contracts, decreased to $1.4 million from $2.2 million, a decrease of
$829,000 or 38% as compared to last year. The decline in total product
technology expenditures is due to decreased spending on The Yellow IRIS family
of products.

        We began a major project in 1999 to improve The Yellow IRIS urinalysis
workstation product line.  As a result, we expect significant increases in our
net research and development expenses above 1999 levels.  We have completed
feasibility studies on the proposed improvements.  We believe that this project
is important to maintaining our competitive position in the urinalysis market
and that our failure to successfully complete this project on schedule could
have a material and adverse effect on future system sales.

<PAGE>   16
        Amortization of intangible assets reflects the amortization of deferred
expenses for warrants issued in connection with a joint development project,
intangible assets arising from an acquisition and patents. Amortization of,
intangible assets for the year ended December 31, 1999 decreased to $231,000
from $278,000, a decrease of $47,000, or 17%, from the prior year. The decline
is the result of the write-off in the third quarter of 1999 of the deferred
warrant costs for technology rights.

        The results of operations for the year ended December 31, 1999 include
unusual expenses of $4.2 million as compared to $193,000 in the prior year. The
increase primarily relates to the write-off of deferred warrant costs
($807,000), write-off of the deferred software development costs associated with
The White IRIS ($797,000), settlement with Poly U/A ($1.7 million), legal and
other expenses relating to the recently completed DITI arbitration totaled
($392,000) net of recovery of $132,000 and expenses in connection with a
retirement agreement ($444,000). The prior year's expenses related to the DITI
arbitration.

        The net result of the above described changes is an operating income of
$390,000 for the year ended December 31, 1999 as compared to an operating income
of $2.2 million in the same period last year. Excluding the litigation
settlement and other unusual charges and the write-off of The White IRIS,
operating income totaled $4.5 million for 1999 as compared to $2.4 million for
last year.

        Interest expense decreased to $966,000 in 1999 from $1.2 million for
last year due to reduced indebtedness, partially offset by the effect of
increased interest rates on the credit facility.

        For the year ended December 31, 1999, urinalysis segment profits
increased to $3.7 million as compared to $2.9 million last year. Excluding the
write-off of The White IRIS inventory and software development costs ($926,000)
and the deferred warrants costs ($807,000), the urinalysis segment profits would
have totaled $5.4 million. This increase is attributable to higher revenues
described above and lower operating expenses. Segment profits from the small
laboratory devices segment totaled $1.4 million, as compared to $1.1 million
last year. If the nonrecurring license fee earned in the prior year were
excluded, this segment's profit for last year totaled $844,000 as compared to
this year's $1.4 million. The increase results from increased product sales and
gross profits. Unallocated corporate expenses totaled $5.6 million in the
current period as compared to $2.9 million last year. The increase is due
primarily to the recently completed arbitration with DITI, the settlement with
Poly U/A and expenses associated with the Office of the Chief Executive and
Board of Directors and a retirement agreement.

        The income tax provision for the year ended December 31, 1999 totaled
$531,000, as compared to a provision of $420,000 for 1998.  The provision for
1999 includes $649,000 relating to an increase in the deferred tax valuation
allowance as a result of management's assessment of operating results, net
operating losses expected to expire in the near term, and other factors.

        The above factors contributed to a loss from continuing operations of
$1,088,000 or $0.15 per share for the year ended December 31, 1999 as compared
to income from continuing operations of $667,000 or $0.09 per share for the
prior year. Excluding the unusual expenses and the write-off of The White IRIS
inventory, related tax benefits and the increase of the deferred income taxes
valuation allowance, the Company would have had net income from continuing
operations of $2.3 million or $0.30 per diluted share in 1999 and net loss of
$789,000, or $0.10 per share in the prior year.

        COMPARISON OF YEAR ENDED DECEMBER 31, 1998 TO YEAR ENDED DECEMBER 31,
1997

        Net revenues for the year ended December 31, 1998 increased to $21.6
million from $20.7 million, an increase of $857,000, or 4%, over last year.
Revenues from sales of urinalysis systems decreased to $5.0 million from $5.6
million, a decrease of $627,000, or 11%. The decrease is due to a decline in
domestic sales, partially offset by increased sales to an international
distributor. Sales of IVD system supplies and services increased to $11.8
million from $10.1 million, an increase of $1.7 million or 17% over the
comparable period last year, primarily due to the larger installed base of The
Yellow IRIS IVD imaging systems. Sales of small instruments and supplies
decreased to $4.3 million from $4.4 million, a decrease of $102,000.

        Royalty and licensing revenue decreased to $465,000 for the year ended
December 31, 1998 as compared to



                                       14
<PAGE>   17
$603,000 in the prior year. The decrease is primarily due to differences in
non-recurring licensing fees received in the two years.

        Revenues from the urinalysis segment totaled $17.0 million for the year
ended December 31, 1998 as compared to $16.2 million in the prior year, an
increase of $816,000. The net increase is due to increased revenues from
supplies and service for The Yellow IRIS which more than offset a decline in
sales of The Yellow IRIS instruments and a decline in licensing revenues.
Revenues from the small laboratory devices segment were essentially comparable
as increased licensing revenues were substantially offset by reduced purchases
by a major distributor.

        Cost of goods for IVD systems increased as a percentage of their sales
to 66% for the year ended December 31, 1998 from 60% for the prior year. The
increase is primarily due to lower average selling prices of The Yellow IRIS
urinalysis workstations caused by an increased proportion of international
sales. Cost of goods for IVD system supplies and services as a percentage of
sales of such products decreased to 46% for the current period as compared to
49% for the prior year. The decrease is primarily due to decreased costs and
increased selling prices. Cost of goods for small instruments and supplies as a
percentage of sales of small instruments and supplies totaled 55% for 1998
compared to 53% for the prior year. The increase is primarily due to a change in
the sales mix. The net result of these changes resulted in an aggregate gross
margin to 49% for 1998, which is comparable to the prior year.

        Cost of goods sold as a percentage of revenues from the urinalysis
segment totaled 68% in 1998, as compared to 51% in 1997. Lower average selling
prices for The Yellow IRIS workstation to an international distributor were
partially offset by improved pricing and decreased costs on supplies and
service. Cost of goods for the small instrument devices segment as a percentage
of revenues totaled 52% in 1998 and 1997.

        Marketing and selling expenses consist primarily of salaries,
commissions and related travel expenses of the Company's direct sales force, as
well as salaries for the marketing and distributor relations departments.
Marketing and selling expenses totaled $3.2 million for the year ended December
31, 1998, and is comparable to the prior year. Marketing and selling expenses as
a percentage of net revenues amounted to 15% in 1998 and 1997.

        General and administrative expenses consist primarily of payroll costs
associated with the Company's management and support personnel, facilities
related costs and legal and accounting fees. General and administrative expenses
increased to $2.7 million for the year ended December 31, 1998 from $2.6
million, an increase of $122,000 or 5% over the prior year, primarily due to
additional executive positions, severance charges and charges associated with
the repricing of options held by consultants. These increases were partially
offset by lower legal and accounting expenses. General and administrative
expenses as a percentage of net revenues totaled 13% in 1998 and 1997.

        Net research and development expenses consist of costs incurred for the
development of new products and improvements to existing products less
third-party reimbursements under joint development programs, grants and research
and development contracts. Net research and development expenses increased to
$1.9 million for the year ended December 31, 1998 from $1.6 million in the prior
year, an increase of $279,000 or 17%, due to increased expenditures and
decreased external funding under joint development programs. Net research and
development expenses as a percentage of net revenues amounted to 9% in 1998 and
8% in 1997. Reimbursements under joint development programs decreased to
$140,000 from $517,000. Total product technology expenditures, including
capitalized software development costs and reimbursed costs under research and
development grants and contracts, totaled to $2.2 million, as compared to $2.5
million the prior year.

        Amortization of intangible assets reflects the amortization of deferred
expenses for warrants issued in connection with joint development projects and
intangible assets arising from acquisitions and patents. Amortization of
intangible assets for the year ended December 31, 1998 decreased to $278,000
from $426,000, a decrease of $148,000 or 35% from the prior period. The decline
is primarily the result of the write-off in the fourth quarter of 1997 of
goodwill from the digital refractometer product line acquired in 1995.

        The results of operations for the year ended December 31, 1998 include
unusual charges of $193,000 relating primarily to legal expenses for a pending
arbitration matter. See "Legal Proceedings." The unusual charges in the



                                       15
<PAGE>   18

prior year totaled $1.3 million and related primarily to the write-off of
deferred private offering expenses, goodwill no longer considered recoverable
associated with the digital refractometer product line and legal expenses.

        The net result of the above-described changes was an increase in
operating income to $2.2 million in 1998, as compared to $1.0 million in the
prior year. For the year ended December 31, 1998, urinalysis segment profits
increased to $2.9 million as compared to $2.7 million in the prior year, an
increase of $147,000 or 5%. This increase is largely attributable to increased
sales of related supplies and service described above, partially offset by a
small increase in operating expenses and lower system margins. Segment profits
from the small laboratory devices segment totaled $1.1 million in 1998 as
compared to $372,000 in 1997. The improvement is due to the increase in this
segment's licensing revenues and the write-off in 1997 of goodwill associated
with the digital refractometer product line. Unallocated corporate expenses
totaled $2.9 million in 1998 as compared to $3.2 million in the prior year, a
decrease of $325,000. This is due to decreased unusual charges for deferred
offering costs and legal expenses as described above.

        The income tax provision for the year ended December 31, 1998 totaled
$420,000 as compared to an income tax benefit of $34,000 for 1997. The income
tax benefit for the year ended December 31, 1998 differs from the federal
statutory rate due to state, local and foreign income taxes and permanent
differences between income reported for financial statement and income tax
purposes.

        The above factors contributed to income from continuing operations of
$667,000 or $0.09 per diluted share for the year ended December 31, 1998 as
compared to a net loss of $58,000 or $0.01 per diluted share for the year ended
December 31, 1997.

LIQUIDITY AND CAPITAL RESOURCES

        Cash and cash equivalents increased to $2.0 million at December 31, 1999
from $389,000 at December 31, 1998. The increase is due to the cash provided by
operations in excess of amounts used by investing and financing activities. Cash
provided by operations for the year ended December 31, 1999 increased to $3.8
million from $960,000 for the comparable period last year. This increase is
primarily due to the decrease in inventory levels, improved operations
(excluding unusual noncash write-offs) and increased accrued liabilities.

        Cash used by investing activities totaled $681,000 for the year ended
December 31, 1999, as compared to $1.2 million in the prior year. The decrease
is primarily due to the decline in expenditures for property and equipment,
offset by the proceeds from the sale of The Yellow IRIS urinalysis workstations
previously subject to an operating lease.

        The credit facility with Foothill Capital Corporation, a Wells Fargo
company, consists of a $3.6 million term loan and a $4.0 million revolving line
of credit. Borrowings under the line of credit are limited to a percentage of
eligible accounts receivable and are subject to a combined limit of $7.0 million
for the total credit facility. The term loan bears interest at the lender's
prime rate (8.5% on December 31, 1999) plus 3.0%, and is payable in 36 equal
monthly installments. The revolving line of credit bears interest at the
lender's prime rate plus 1.0%. The credit facility is subject to minimum
interest charges, prepayment penalties and customary fees, is collateralized by
a first priority lien on all the assets of the Company and matures in 2001. It
also contains financial covenants based primarily on tangible net worth and cash
flow and imposes restrictions on acquisitions, capital expenditures and cash
dividends. We were not in compliance with one of these financial covenants at
year end, and the credit facility has been amended to waive the non-compliance
and modify the financial covenants for future periods.

        We began a major project in 1999 to improve The Yellow Iris urinalysis
workstation product line.  As a result, we expect significant increases in our
research and development expenditures.  We plan to fund this project with cash
from operations.

        Net cash used by financing activities totaled $1.5 million and consisted
primarily of principal payments made on the term loan described above and notes
payable due to Corange International Limited, an affiliate of the Boehringer
Mannheim group of companies, partially offset by net proceeds from
borrowings on the revolving line of credit. As of December 31, 1999, $1.7
million was outstanding under the term loan and $655,000 was outstanding under
the revolving line of credit; $2.0 million remained available for future
borrowings under the revolving credit line.

        We reduced our outstanding debt by $1.8 million in 1999 and we have
scheduled principal payments totaling $1.2 million during the next twelve
months. We believe that our current cash on hand, together with cash generated
from operations and cash available under the credit facility, will be sufficient
to fund normal operations and pay principal and interest on outstanding debt
obligations for the next 19 months. On July 31, 2001, our $7.0 million
subordinated note becomes due and payable. We anticipate that we will have to
seek proceeds from a debt or equity financing in order to meet this obligation.

        We issued 198,000 shares of Series B Callable Preferred Stock in
connection with the tender offer for Poly U/A. See "--Overview." These shares
have a liquidation preference of $3 per share (or an aggregate liquidation
preference of $594,000). The "callable" feature entitles us to convert the
preferred stock at any time into a number of shares of common stock equal to the
liquidation value divided by the market price of the common stock at the time of
conversion (subject to a minimum value of $2.00 per share of common stock). The
preferred stock will automatically convert under the same formula on August 3,
2002 if we have not converted it sooner. Based on the average closing price of
$0.76 for the five-day period ending December 31, 1999, the call price would be
the $2.00 minimum, and we could convert the Series B Callable Preferred Stock
into 297,000 shares of common stock. The Series B Callable Preferred Stock is
non-voting, is not entitled to any preferred dividends, and is not subject to
any mandatory or optional redemption provisions. We are not permitted to pay
cash dividends on our common stock or to repurchase any shares of our common
stock without the written consent of the holders of a majority of the Series B
Callable Preferred Stock.

DISCONTINUED BUSINESS OPERATIONS

        We acquired Perceptive Scientific Instruments in July 1996. Its
principal product line is the PowerGene family of genetic analyzers -- IVD
imaging systems for karyotyping, DNA probe analysis and comparative genomic
hybridization. In March of 2000, we entered into a letter of intent to sell
this business to a well-known international company for an estimated price of
$2.5 to $5.0 million in cash. The exact price depends on the results of the
buyer's remaining due diligence and the satisfaction of certain conditions. The
most significant condition is the successful transfer of certain government
research contracts to the buyer, and this may require governmental approval.

        In light of our plans to sell Perceptive Scientific Instruments, we are
treating this business as a discontinued operation for accounting purposes, and
we have removed it from most of the discussion and financial information and in
this Annual Report to reflect this treatment. However, the letter of intent is
not a binding agreement, and we cannot be sure that this transaction will occur.
Closing this transaction depends upon the outcome of the buyer's remaining due
diligence, the satisfaction of various conditions set by the buyer, negotiating
and signing a definitive written sale agreement and board of director approval
from both companies. If this sale does not occur, we plan to pursue other
opportunities for a disposition of this business.

SHAREHOLDER RIGHTS PLAN

        We adopted a shareholders rights plan in December 1999.  The rights are
not presently exercisable.  They become exercisable only if a person or group
acquires 20% or more of our common stock, or announces a tender offer for 20%
or more of our common stock, without board approval.  If the rights are
triggered, all common stockholders (except the hostile party) will be entitled
to purchase shares of common stock (or the economic equivalent in preferred
stock) at a price based on a substantial discount from the market price of the
common stock. The Board of Directors may terminate the plan at any time or
redeem the rights prior to their becoming exercisable.  The rights expire on
December 22, 2009.

NET OPERATING LOSS CARRYFORWARDS

        At December 31, 1999, we had federal net operating loss carryforwards of
approximately $17.5 million. If substantially all of our outstanding options and
warrants, including the warrants issued in the Poly/UA transaction, are
exercised on or before December 31, 1999, these transactions in combination with
other prior stock issuances during the past three years would constitute a
"change of ownership" under Section 382 of the Internal Revenue



                                       17
<PAGE>   20

Code. Section 382 imposes an annual limitation on the utilization of net
operating loss carryforwards based on a statutory rate of return (usually the
applicable federal rate) and the value of the corporation at the time of the
change of ownership. Depending on the market price of our common stock at the
time a change of ownership occurs, the resulting limitations imposed by Section
382 could trigger a substantial write down in our deferred tax assets and a
corresponding charge to earnings in the relevant quarter.

YEAR 2000 PROBLEM

        The Year 2000, or Y2K, problem arose because many existing computer
programs use only the last two digits to recognize a year. This issue has not
had a material adverse effect on our operations.

MARKET RISK

        Our business is exposed to various market risks, including changes in
interest rates and foreign currency exchange rates. Market risk is the potential
loss arising from adverse changes in market rates and prices, such as interest
rates and foreign currency exchange rates. We do not enter into derivatives or
other financial instruments for trading or speculative purposes.

Interest Rates

        We rely significantly on long- and short-term fixed and variable rate
debt in our capital structure. We do not use interest rate swaps to manage any
of our floating-rate debt obligations. As of December 31, 1999, our debt
obligations consisted of (1) $7.0 million outstanding under an 8.5% fixed rate
subordinated note, (2) $1.7 million outstanding under a variable rate term loan
and (3) $655,000 outstanding under a variable rate revolving line of credit. The
variable rate obligations are based upon the lender's prime rate. See "--
Liquidity and Capital Resources." Assuming an increase of one-half of a
percentage point in the lender's prime rate on January 1, 2000 and no principal
payments for the remainder of the year, our total interest expense would
increase by less than $100,000 for 2000 as compared to 1999.

Foreign Currencies

        We are subject to some currency risk on a portion of our licensing
revenues. This portion is calculated quarterly based on sales results in
Japanese Yen and subsequently converted into United States dollars at the then
current exchange rate.

INFLATION

        We do not foresee any material impact on our operations from inflation.

HEALTHCARE REFORM POLICIES

        In recent years, an increasing number of legislative proposals have been
introduced or proposed in Congress and in some state legislatures that would
effect major changes in the healthcare system, nationally, at the state level or
both. Future legislation, regulation or payment policies of Medicare, Medicaid,
private health insurance plans, health maintenance organizations and other
third-party payors could adversely affect the demand for our current or future
products and our ability to sell our products on a profitable basis. Moreover,
healthcare legislation is an area of extensive and dynamic change, and we cannot
predict future legislative changes in the healthcare field or their impact on
our business.

FORWARD-LOOKING STATEMENTS

        This Annual Report on Form 10-K contains forward-looking statements
which reflect our current views about future events and financial results. We
have made these statements in reliance on the safe harbor created by that
Private Securities Litigation Reform Act of 1995. Forward-looking statements
include our views on future financial results, financing sources, product
development, capital requirements, market growth and the like, and are generally
identified by phrases such as "anticipates," "believes," "estimates," "expects,"
"intends," "plans" and similar words. Forward-looking statements are merely
predictions and therefore inherently subject to uncertainties and other factors
which could cause the actual results to differ materially from the
forward-looking statement. These uncertainties and other factors include, among
other things,

        -       our ability to secure additional financing to repay the
                remaining principal balance of our long-term debt and to fund
                our long-term business strategy,

        -       unexpected technical and marketing difficulties inherent in
                major product development efforts such as the new platform for
                The Yellow IRIS,

        -       the potential need for changes in our long-term strategy in
                response to future developments,

        -       future advances in diagnostic testing methods and procedures, as
                well as potential changes in government regulations and
                healthcare policies, both of which could adversely affect the
                economics of the diagnostic testing procedures automated by our
                products,

        -       rapid technological change in the microelectronics and software
                industries, and

        -       increasing competition from imaging and non-imaging based
                in-vitro diagnostic products.

        We have attempted to identify additional significant uncertainties and
other factors affecting forward-looking statements in Exhibit 99 to this Annual
Report. Stockholders should understand that the uncertainties and other factors
identified in this Annual Report and in Exhibit 99 are not a comprehensive list
of all the uncertainties and other factors which may affect forward-looking
statements. We do not undertake any obligation to update or revise any
forward-looking statements or the list of uncertainties and other factors which
could affect those statements.

NEW ACCOUNTING PRONOUNCEMENTS

        In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements," which provides the SEC's views on applying generally accepted
accounting principles to selected revenue recognition issues. The Company is
presently evaluating the impact, if any, that this may have on the Company's
revenue recognition policies.

                        REPORT OF INDEPENDENT ACCOUNTANTS




To the Board of Directors and Shareholders
of International Remote Imaging Systems, Inc.

        In our opinion, the consolidated financial statements listed in the
index appearing under Item 14(a)1 present fairly, in all material respects, the
financial position of International Remote Imaging Systems, Inc., and its
subsidiaries at December 31, 1999 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1999, in conformity with accounting principles generally accepted in the
United States. In addition, in our opinion, the financial statement schedule
listed in the index appearing under Item 14(a)2 presents fairly, in all material
respects, the information set forth therein when read in conjunction with the
related consolidated financial statements. These financial statements and
financial statement schedule are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally accepted in the
United States which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   INTERNATIONAL REMOTE IMAGING SYSTEMS, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. FORMATION AND BUSINESS OF THE COMPANY.

        International Remote Imaging Systems, Inc. and its subsidiaries
(collectively "IRIS" or the "Company"), was incorporated in California in 1979
and reincorporated during 1987 in Delaware. The Company designs, develops,
manufactures and markets in vitro diagnostic ("IVD") equipment, including IVD
imaging systems based on patented and proprietary automated intelligent
microscopy ("AIM") technology, as well as special purpose centrifuges and other
small instruments for automating microscopic procedures performed in clinical
laboratories.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.

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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. The significant estimates in the preparation of the
consolidated financial statements relate to the assessment of the carrying value
of accounts receivables, inventories, purchased intangibles, estimated
provisions for warranty costs and deferred tax assets. Actual results could
differ from those estimates.

Principles of Consolidation


        The financial statements include the accounts of International Remote
Imaging Systems, Inc. and its subsidiaries. All intercompany accounts and
transactions have been eliminated in the consolidated financial statements.

Foreign Currency

        The financial statements of the Company's foreign subsidiary are
translated into U.S. dollars using the exchange rate prevailing at each balance
sheet date for assets and liabilities and average exchange rates for each
reporting period for revenues and expenses. Translation adjustments are recorded
directly to a separate component of shareholders' equity. Gains and losses
resulting from foreign currency transactions are included in operations.

Cash Equivalents and Short-Term Investments

        Short-term investments principally include certificates of deposit and
debt instruments of the United States Government with maturities greater than
three months and less than one year. For purposes of the statement of cash
flows, IRIS considers all highly liquid debt instruments purchased with a
remaining maturity of three months or less when purchased to be cash
equivalents. IRIS places its cash and investments with high credit quality
financial institutions. At times, these deposits may be in excess of the
federally insured limit.

Accounts Receivable

        IRIS sells predominantly to entities in the healthcare industry. IRIS
grants uncollateralized credit to its customers, primarily hospitals, clinical
and research laboratories, and distributors. IRIS performs ongoing credit
evaluations of its customers before granting uncollateralized credit. The
Company does not have any single customer which accounts for 10% or more of its
consolidated revenues.



                                      F-10
<PAGE>   37

Inventories

        Inventories are carried at the lower of cost or market on a first in,
first out basis. Provision for potentially obsolete or slow-moving inventory is
made based on management's analysis of inventory levels and future sales
forecasts.

Property and Equipment and Depreciation

        Property and equipment are recorded at cost, less accumulated
depreciation and amortization. Depreciation is generally computed using the
straight-line method over three to five years, the estimated useful lives of the
assets. Leasehold improvements are amortized over the lesser of their useful
life or the remaining term of the lease.

        Costs of maintenance and repairs are charged to expense when incurred;
costs of renewals and betterments are capitalized. Upon sale or retirement, the
cost and related accumulated depreciation are eliminated from the respective
accounts, and the resulting gain or loss is included in current income.

Purchased Intangibles

        Purchased intangibles are recorded at cost and consist of goodwill,
acquired technology and know-how and international distribution channel, and are
being amortized on a straight-line basis over ten years, six years and
twenty-five years, respectively. The realizability of purchased intangibles is
evaluated periodically as events or circumstances indicate a possible inability
to recover the carrying amount. Such evaluation is based on various analysis,
including cash flow and profitability projections. The analysis necessarily
involves significant management judgement to evaluate the capacity of an
acquired business to perform within projections. In the event the projected
undiscounted cash flows are less than net book value of the assets, the carrying
value of the assets will be written down to their fair value.

Software Development Costs

        The Company capitalizes certain software development costs for new
products and product enhancements once all planning, designing, coding and
testing activities necessary to establish that the product can be produced to
meet its design specifications are completed, and concludes capitalization when
the product is ready for general release. Research and development costs
relating to software development are expensed as incurred. Amortization of
capitalized software development costs is provided on a product-by-product basis
at the greater of the amount computed using (a) the ratio of current revenues
for a product to the total of current and anticipated future revenues or (b) the
straight-line method over the remaining estimated economic life of the product.
Generally, an original estimated economic life of one and one half years to
three years is assigned to capitalized software development costs. Amortization
expense of software development costs, excluding the write off of costs relating
to the White IRIS of $796,887 (Note 16) in 1999, was $375,721, $334,996 and
$223,813 for 1997, 1998 and 1999, respectively.

Deferred Warrant Costs

        Deferred warrant costs are included in other assets and result from the
issuance of warrants in conjunction with various development, distribution and
technology license agreements. These costs were generally being amortized over
the estimated term of the related agreements. During 1999, as a result of
certain events described in Note 16, a charge of $807,244 was recorded for the
write-down of this asset in the third quarter of 1999.

Long-Lived Assets

        The Company identifies and records impairment losses for long-lived
assets whenever events or changes in circumstances result in the carrying amount
of the assets exceeding the sum of the expected future undiscounted cash flows
associated with such assets. The measurement of the impairment losses recognized
is based on the difference between the fair values and the carrying amounts of
the assets.  During 1997, as a result of a distributor notifying the Company
that they would no longer carry the digital refractometer line,



                                      F-11
<PAGE>   38

a $704,579 charge was recorded for the write-down of long-lived assets in the
fourth quarter of 1997. As described in Notes 7 and 16, a $8,160,978 charge was
recorded for the write-down of long-lived assets in the third quarter of 1999.

Stock Based Compensation

        The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." SFAS No. 123 defines a fair value
based method of accounting for an employee stock option. Fair value of the stock
option is determined considering factors such as the exercise price, the
expected life of the option, the current price of the underlying stock and its
volatility, expected dividends on the stock, and the risk-free interest rate for
the expected term of the option. Under the fair value based method, compensation
cost is measured at the grant date based on the fair value of the award and is
recognized over the service period. Pro forma disclosures for entities that
elect to continue to measure compensation cost under the intrinsic method
provided by Accounting Principles Board Opinion No. 25 must include the effects
of all awards granted in fiscal years that begin after December 15, 1994. An
expense is recognized for common stock, warrants or options issued or repriced,
for services rendered by non-employees based on the estimated fair value of the
security exchanged.

Revenue Recognition

        IRIS derives revenue from the sale of IVD imaging systems, sales of
supplies and service for its IVD imaging systems and sales of small laboratory
instruments and related supplies. IRIS generally recognizes product revenues
once all of the following conditions have been met: a) an authorized purchase
order has been received in writing, b) customer credit worthiness has been
established, and c) delivery of the product to the customer designated location
has occurred. Estimated installation expense is recognized at the time of
delivery.

        IRIS recognizes service revenues ratably over the term of the service
period, which typically ranges from twelve to sixty months. Payments for service
contracts are generally made in advance. Deferred revenue represents the
revenues to be recognized over the remaining term of the service contracts.

Warranties

        IRIS recognizes the full estimated cost of warranty expense at the time
of product delivery.

Research and Development Expenditures

        Except for certain software development costs required to be capitalized
as described above (see Software Development Costs), research and development
expenditures are charged to operations as incurred. Net research and development
expense includes total research and development costs incurred, including costs
incurred under research and development grants and contracts, less costs
reimbursed under research and development contracts.

Income Taxes

        IRIS accounts for income taxes in accordance with SFAS No. 109
"Accounting for Income Taxes," which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
differences between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.
Income tax expense represents the tax payable for the period and the change
during the period in deferred tax assets and liabilities.

Marketing Costs



                                      F-12
<PAGE>   39

        All costs related to marketing and advertising the Company's products
are expensed at the time the advertising takes place.

Fair Value of Financial Instruments

        The amount recorded for financial instruments in the Company's
consolidated financial statements approximates fair value as defined in SFAS No.
107, "Disclosures about Fair Value of Financial Instruments," except for the
subordinated note described in Note 9 of which the fair value is not readily
determinable.

Earnings Per Share

        Basic earnings per share is computed by dividing net income (loss) by
the weighted average number of common shares outstanding. Diluted earnings per
share is computed by dividing net income (loss) by the weighted average number
of common shares and common stock equivalents outstanding, calculated on the
treasury stock method. Common stock equivalents are excluded from the
computation when their effect is antidilutive.

Segment Reporting

        In the second quarter of 1998, the Company adopted SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information". SFAS No.
131 supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise," replacing the "industry segment" approach with the "management"
approach. The management approach designates the internal organization that is
used by management for making operating decisions and assessing performance as
the source of the Company's reportable segments, SFAS No. 131 also requires
disclosures about products and services, geographic areas, and major customers.
The adoption of SFAS No. 131 did not affect results of operations or financial
position but did affect the disclosure of segment information. See Note 17 --
"Segment and Geographic Information".

Reclassifications

        Certain reclassifications have been made to the 1997 and 1998 financial
statements to conform with the 1999 presentation.

Certain Risks and Uncertainties

        Dependence on Instrument Sales: The Company derives most of its revenues
from the sale of The Yellow IRIS urinalysis workstations, and related supplies
and services. These instruments have list prices ranging from approximately
$100,000 to $195,000 depending on model and configuration, and relatively modest
declines in unit sales or gross margins for either product line could have a
material adverse effect on the Company's revenues and profits.

        Reliance on Single Source Suppliers: Certain key components of the
Company's instruments are manufactured according to the Company's specifications
or are available only from single suppliers. For example, Roche Diagnostics is
the sole supplier for the Company's proprietary CHEMSTRIP/IRIStrip urine test
strips and related test reader used in The Yellow IRIS Models 300 and 500. From
time to time, single source suppliers have discontinued production of key
components or encountered production problems which potentially could have a
material adverse effect on instrument sales. Although, in the past, the Company
has successfully transitioned to new components to replace discontinued
components, there can be no assurance that the Company can always successfully
transition to satisfactory replacement components or that the Company will
always have access to adequate supplies of discontinued components on
satisfactory terms during the transition period. The Company's inability to
transition successfully to replacement components or to secure adequate supplies
of discontinued components on satisfactory terms could have a material adverse
effect on the Company.

        In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements," which provides the SEC's views on applying generally accepted
accounting principles to selected revenue recognition issues. The Company is
presently evaluating the impact, if any, that this bulletin may have on the
Company's revenue recognition policy.

        Any lease that does not meet the criteria for a sales-type or a
financing lease is accounted for as an operating lease. Under these leases the
Company also provides supplies and services. Generally operating leases are for
periods less than one year and contain provisions for renewal and early
termination penalties.  The cost of leased systems is depreciated to a zero
value on a straight-line basis over five years. Accumulated depreciation on
leased systems was $413,992, and $606,087 at December 31, 1998 and 1999,
respectively.

        Future minimum lease payments due from customers under sales-type leases
and noncancellable operating leases as of December 31, 1999 are as follows:

        The Company acquired most of these intangibles in connection with the
1996 acquisition of its genetic analysis business which is currently operated
through Perceptive Scientific Instruments, Inc, a wholly-owned subsidiary.
Following the recent transition to a new chief executive officer, the Company
reviewed the recoverability of these assets as part of an overall reassessment
of its business. Based primarily upon this segment's continued losses and
generally weakened market, the Company revised its forecasted cash flows
(undiscounted and without interest charges) from this business segment and
determined that they would be negative and insufficient to recover the cost of
these intangible assets. As a result, the Company wrote-off the remaining
unamortized amount of these intangible assets by recording a $6,556,847 charge
to earnings in the



                                      F-15

third quarter of 1999 as an impairment loss. This charge has been included in
loss from discontinued operations (see Note 15).

9. SHORT-TERM BORROWINGS AND NOTES PAYABLE.

        At December 31, 1999, the outstanding amounts under the Company's credit
facility consists of $1.7 million of a $3.6 million term loan and $655,036 of a
$4.0 million revolving line of credit. Borrowings under the line of credit are
limited to a percentage of eligible accounts receivable. The Company had
approximately $2.0 million available under the line of credit at December 31,
1999. The term loan bears interest at the lender's prime rate (8.5% on December
31, 1999) plus 3.0% and is payable in monthly installments of $100,000. The
revolving credit line bears interest at the lender's prime rate plus 1.0%. The
credit facility is subject to minimum interest charges, prepayment penalties
and customary fees, is collateralized by a first priority lien on all assets of
the Company and matures in 2001. It also contains financial covenants based
primarily on tangible net worth and cash flows and imposes restrictions on
acquisition, capital expenditures and cash dividends.

        The outstanding principal balance on the Subordinated Note was $7.0
million on December 31, 1999. The Subordinated Note bears interest at a fixed
rate of 8.5% per annum, payable in quarterly installments. The entire principal
is due on or before July 31, 2001. The Company may prepay the Subordinated Note
at any time without premium or penalty. Upon the issuance by the Company of
equity securities generating net proceeds in excess of $14.5 million, the
Company must apply fifty percent of the excess to the prepayment of the
Subordinated Note. The payment of principal and interest on the Subordinated
Note is subordinated in right of payment, to the extent and in the manner
provided therein, to the prior payment in full of the credit facility.

        Annual maturities of long term borrowings are $1,200,000 (2000) and
$7,500,000 (2001).

10. INCOME TAXES.

        At December 31, 1999, the Company had federal net operating loss
carryforwards of approximately $17.5 million and state net operating loss
carryforwards of approximately $2.3 million which expire in fiscal years
ending in 2000 through 2013. As of December 31, 1999, IRIS had investment tax,
research and experimentation and foreign tax credit carryforwards of $210,000
expiring in fiscal years through 2004.

        The primary components of temporary differences which give rise to the
Company's net deferred tax asset at December 31, 1997, 1998 and 1999 are as
follows:

</TABLE>

        At December 31, 1999, the Company increased the valuation allowance by
$649,000 based on its current assessment of operating results, net operating
loss carry-forwards scheduled to expire in the near term, and other factors.

        Realization of deferred tax assets associated with net operating losses
("NOL") and tax credit carryforwards is dependent upon generating sufficient
taxable income prior to their expiration. Management believes that there is a
risk that certain of these NOL and tax credit carryforwards may expire unused
and accordingly, has established a



                                      F-17
<PAGE>   44

valuation allowance against them. Although realization is not assured for the
remaining deferred tax assets, management believes it is more likely than not
that they will be realized through future taxable income or alternative tax
strategies. However, the net deferred tax assets could be reduced in the near
term if management's estimates of taxable income during the carryforward period
are significantly reduced or alternative tax strategies are not available. The
Company will continue to review its valuation allowances and make adjustments,
if necessary. Also, although a valuation allowance has been provided against a
portion of its NOL's, should the Company undergo an ownership change as defined
in Section 382 of the Internal Revenue Code, the Company's NOL generated prior
to the ownership change would be subject to an annual limitation. If this
occurs, a further adjustment of the valuation allowance may be necessary.

11. CAPITAL STOCK.

Preferred Stock

        On December 31, 1996, the Company sold (i) 3,000 shares of a new Series
A Convertible Preferred Stock ("Preferred Stock") with a liquidation value of
$1,000 per share.  Each share of Preferred Stock was convertible into a number
of shares of common stock equal to the liquidation value of a share of Preferred
Stock divided by a conversion price.  The Conversion Price was equal to the
lower of (i) 85% of the average closing bid price of the common stock for
the five consecutive trading days immediately preceding the conversion date (but
in no event less than $1.50) or (ii) $3.56. On October 1, 1999, the Series A
Preferred stockholder converted its investment into two million shares of common
stock.  In 1997, for purposes of calculating earnings per share, the potential
discount on the conversion of the Preferred Stock was treated as an embedded
dividend to the preferred stockholders which reduces the amount of income
available to common stockholders.

        During the year ended December 31, 1999, the Company successfully
completed a tender offer for the common stock of Poly UA Systems, Inc., a
Company-sponsored research and development entity. In exchange for the tendered
shares and a release of claims, the Company issued to the tendering stockholders
a total of 594,000 shares of common stock, 198,000 shares of a new Series B
Callable Preferred Stock and Series G Warrants to purchase an additional 594,000
shares of the Common Stock. The Series B shares have a liquidation preference of
$3 per share (or an aggregate liquidation preference of $594,000). The
"callable" feature entitles the Company to convert the preferred stock at any
time into a number of shares of common stock equal to the liquidation value
divided by the market price of the common stock at the time of conversion
(subject to a minimum value of $2 per share of common stock). The preferred
stock will automatically convert under the same formula on August 3, 2002, if
not converted sooner by the Company. The Series B Callable Preferred Stock is
non-voting, is not entitled to any preferred dividends and is not subject to any
mandatory or optional redemption provisions. The Company may not pay cash
dividends on the common stock or repurchase any shares of the common stock
without the written consent of the holders of a majority of the Series B
Callable Preferred Stock.

Shareholders' Rights Plan

        The Company has a shareholders' rights plan under which each holder of a
share of common stock also has one right to purchase one one-thousandth of a
newly created Series C preferred share at $9 per one one-thousandth of a share.
The rights are not presently exercisable. Upon the occurrence of certain
"flip-in" events, each right becomes exercisable which then entitles its holder
to receive the number of common shares having an aggregate per share market
price equal to two times the purchase price. Upon certain "flip-over" events,
each right when exercised entitles its holder to receive common share of the
acquiring company having a value equal to two times the purchase price. One
flip-in event is when a person or group (an "acquiring person") acquires 20
percent or more of the company's common stock. Rights held by an acquiring
person are void. The Company may redeem the rights for one cent per share. The
rights expire on December 22, 2009.

Stock Issuances

<PAGE>   45

        During 1990, the IRIS Board of Directors adopted an Employee Stock
Purchase Plan designed to allow employees of the Company to buy its shares at
50% of the then current market price, provided that the employee agrees to hold
the shares purchased for a minimum of two years. The employee's 50% portion of
stock purchases under the plan may not exceed 15% of the employee's salary
during any year. The remaining 50% portion is recorded as deferred compensation
and amortized over the vesting period. The shares purchased pursuant to this
plan may not be transferred, except following the death of the employee or a
change in control, for a period of two years following the date of purchase.
During the period of the limitation on transfer, the Company has the option to
repurchase the shares at the employee's purchase price if the employee
terminates employment with the Company either voluntarily or as a result of
termination for cause. During 1997, 1998 and 1999 IRIS issued 69,928, 157,175
and 320,450 shares of common stock, respectively, in exchange for $281,616,
$252,104 and $238,462 in cash and services, respectively, under this plan

Stock Option Plans and Employee Benefit Plans

        As of December 31, 1999, the Company had three stock option plans under
which it may grant non-qualified stock options, incentive stock options and
stock appreciation rights. No stock appreciation rights or incentive stock
options have been granted under these plans.

        The following schedule sets forth options authorized, exercised,
outstanding and available for grant under the Company's three stock option plans
as of December 31, 1999.

</TABLE>

        The exercise price of options is determined by the Compensation
Committee. Payment of the exercise price may be made in cash or
with shares of common stock. The options generally vest over three years and
expire either five or ten years from the date of grant. On November 6, 1998, the
Board of Directors acted to reprice all outstanding stock options to a maximum
of $1.31 per share, the current market price as of that date. Also, any common
stock acquired upon exercise of the repriced options cannot be resold without
the Board of Directors approval until January 1, 2000.

        IRIS has adopted the disclosure only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation." If compensation expense for the stock options had been determined
using "fair value" at the grant date for awards in 1997, 1998 and 1999,
consistent with the provisions of Statement of Financial Accounting Standards
No. 123, the Company's net loss and loss per share would have been reduced to
the pro forma amounts indicated below:

</TABLE>

        During the year ended December 31, 1999, the Company issued 150,000
options at $1-1/16, subject to the authorization of additional shares under an
existing stock option plan. If the Company is unable to obtain shareholder
approval of these options within twelve months, a stock appreciation right will
be issued for 125,000 of these options retroactive to the original issue date
with the same exercise price, duration and vesting as the original option. The
Company is accounting for these options as stock appreciation rights until
shareholder approval is obtained. No compensation expense relating to these
options was recognized in the current year due to the market value of the common
stock being below the exercise price at December 31, 1999.

Litigation

        From time to time, the Company is party to certain litigation arising
from the normal course of business. Management believes that the resolution of
these matters will not have a material adverse effect on the Company's financial
position, results of operations or cash flows.

13. EARNINGS PER SHARE.

        The computation of per share amounts for 1997, 1998 and 1999 is based on
the average number of common shares outstanding for the period. Options and
warrants to purchase 3,072,203 shares of common stock and 842,697 shares on
conversion of preferred stock were not considered in the computation of diluted
EPS for 1997 because their inclusion would have been antidilutive. Options and
warrants to purchase 3,951,354 shares of common stock and 297,000 shares on
conversion of preferred stock were not considered in the computation of diluted
EPS for 1999 because their inclusion would have been antidilutive.

        The following is a reconciliation of shares used in computing basic and
diluted earnings per share for 1998:

16. UNUSUAL CHARGES.

        The results of operations for the year ended December 31, 1997 include
certain unusual charges to earnings of $1,338,338 primarily for the write-off of
deferred offering costs ($481,325), goodwill associated with the digital
refractometer line of business ($704,579) and certain legal expenses ($152,434)
related to patent litigation and arbitration against Digital Imaging
Technologies, Inc. ("DITI"), relating to the acquisition of PSI. Unusual charges
for the year ended December 31, 1998 totaled $193,186 and related primarily to
the arbitration matter.

        The results of operations for year ended December 31, 1999 include
litigation settlement and other unusual charges totaling $4,158,894. These
charges primarily consist of (1) the settlement expense recorded in connection
with the tender offer for Poly U/A Systems, Inc. ($1,670,127), (2) the cost of
the arbitration with DITI ($391,831), (3) the write-off of deferred warrant
costs for technology rights from Poly U/A Systems ($807,244), (4) the write-off
of deferred costs related to The White IRIS leukocyte differential analyzer
program ($796,887), and (5) expenses in connection with the prior CEO's
retirement agreement ($443,805).

        In September 1995, the Company and Poly U/A Systems Inc., a
Company-sponsored research and development entity ("Poly UA"), entered into a
joint development project for the development of several new products to enhance
automated urinalysis using the Company's technology. As part of the terms of the
project, the Company issued warrants to purchase 512,000 shares of its common
stock in exchange for rights to certain technology and began amortizing the cost
of these warrants. During the fall of 1998, the Company decided not to exercise
a previously negotiated $5.1 million option to acquire the remaining rights to
the technology through an acquisition of Poly UA. The Company later acquired 77%
of the Poly UA common stock from certain stockholders, primarily to avoid
litigation, in exchange for a package of Company securities. In connection with
this transaction, the Company recorded litigation settlement expense of
$1,520,371 in the first quarter of 1999 and $149,756 in subsequent quarters of
1999.

        Following a recent transition to a new chief executive officer, the
Company conducted a reassessment of its



                                      F-23
<PAGE>   50

business and developed a new, near-term business plan. The technology rights
acquired in 1995 from Poly UA for warrants are not used in the new business
plan. As a result, the Company wrote-off the remaining unamortized cost of the
warrants ($807,244) in the third quarter of 1999 (included in unusual expenses).

        Similarly, the Company elected not to include The White IRIS leukocyte
analyzer in its new, near-term business plan and therefore wrote off in the
third quarter $796,887 of capitalized software development costs (included in
unusual expenses) and $128,615 of inventory related to The White IRIS (included
in IVD systems cost of goods sold).

17. SEGMENT AND GEOGRAPHIC INFORMATION.

        The Company's continuing operations are organized on the basis of
products and related services and under SFAS No. 131 operates in two segments:
(1) urinalysis and (2) small laboratory devices.

        The urinalysis segment designs, develops, manufactures and markets IVD
systems based on patented and proprietary AIM technology for automating
microscopic procedures for urinalysis. In December 1997, this segment also began
distributing the UF-100 urine cell analyzer in the United States under an
existing agreement with its manufacturer. The segment also provides ongoing
sales of supplies and service necessary for the operation of installed
urinalysis workstations. In the United States, these products are sold through a
direct sales force. Internationally, these products are sold through
distributors.

        The small laboratory devices segment designs, develops, manufactures and
markets a variety of benchtop centrifuges, small instruments and supplies. These
products are used primarily for manual specimen preparation and dedicated
applications in coagulation, cytology, hematology and urinalysis. These products
are sold worldwide through distributors.

        The accounting policies of the segments are the same as those described
in the "Summary of Significant Accounting Policies" included in this annual
report for the year ended December 31, 1999. The Company evaluates the
performance of its segments and allocates resources to them based on earnings
before income taxes, excluding corporate charges ("Segment Profit").

                   INTERNATIONAL REMOTE IMAGING SYSTEMS, INC.
                          Employee Stock Purchase Plan

                  (As amended and restated on October 31, 1999)


        1. Participants. All employees and directors of International Remote
Imaging Systems, Inc. (the "COMPANY") may participate in the Employee Stock
Purchase Plan (the "PLAN").

        2. Method of Purchase. To purchase shares under the Plan, a participant
must complete, sign and deliver a Direct Purchase Authorization form for each
transaction, along with payment in full in cash for the dollar amount to be
purchased, to the Controller of the Company. The participant must specify a date
of purchase in the form, and the form and payment must be delivered to the
Controller at least 3 business days prior to the desired date of purchase.
Without prior approval from the Compensation Committee of the Board of
Directors, no person may invest more than 15% of his or her annual cash
compensation from the Company. Annual cash compensation consists of (i) an
employee's base salary plus cash bonuses and commissions or (ii) a director's
annual retainer plus any additional cash director fees for service beyond
normal, routine board services. With respect to any particular date, the
calculation of the 15% investment limit will be based on the individual's then
annual base salary rate or annual retainer rate for that calendar year, plus any
bonuses, commissions and additional director fees actually paid through the date
of calculation in that calendar year. Accrued vacation and Company contributions
to any retirement plan will not be included in the calculation.

        3. Price per Share. Participants may purchase common stock at a price
per share equal to 50% of the greater of (i) the average closing price of the
common stock on the American Stock Exchange for the 10 consecutive trading days
ending on date of purchase or (ii) the closing price of the common stock on the
American Stock Exchange on the date of purchase. The minimum transaction size is
$1,000. Fractional shares will not be issued, and any funds remaining after
purchasing an even number of shares will be refunded.

        4. Restriction on Transfer; Option to Repurchase. The shares purchased
under this Plan must be held and may not be transferred for two (2) years
following the date of purchase except following the death of the participant or
a Change in Control of the Company (as defined below). During the two-year
holding period, the Company will have the option to repurchase the shares if the
participant resigns or is terminated. If the participant resigns or is
terminated for cause, the purchase price will be the amount originally paid by
the participant for the shares to be repurchased. If the participant is
terminated without cause, the purchase price will be the average closing price
of the common stock on the American Stock Exchange for the 10 consecutive
trading days ending on the date of termination or resignation (but not less than
the amount originally paid by the participant). Certificates shall bear a legend
relating to the restriction on transfer and the Company's repurchase option.

        5. Administration; Termination; Amendment. Any questions relating to the
administration of this Plan will be determined in good faith by the Compensation
Committee. This Plan may be terminated or amended at any time by the Board of
Directors or its Compensation Committee without prior notice to the
participants.

        6. Tax Effect; Withholding Obligations. This Plan is not qualified under
Section 401(a)



                                       5
<PAGE>   2

(Qualified Pension, Profit-Sharing, and Stock Bonus Plans) or Section 423
(Employee Stock Purchase Plans) of the Internal Revenue Code of 1986.
Accordingly, under current federal tax law, participants must pay taxes on the
discounted purchase of common stock under the Plan for the tax year in which the
2-year restriction period described in paragraph 4 lapses. Upon the lapse of
this restriction, the Company will (i) request an immediate lump sum payment to
satisfy its legally mandated withholding obligation or (ii) deduct the amount
due from the participant's payroll checks or other cash compensation. The
Company may hold any shares of common stock purchased under this Plan until the
participant has satisfied the withholding obligation.

        7. Change in Control. A "Change in Control" means any of the following
events: (i) the dissolution or liquidation of the Company, (ii) a sale of
substantially all the assets of the Company, (iii) a reorganization, merger or
consolidation of the Company with one or more corporations as a result of which
the outstanding common stock of the Company is converted to cash, securities of
another corporation or other property (unless the principal purpose of such
transaction is to change the State of incorporation of the Company or the
shareholders of the Company receive in excess of 60% of the voting stock of such
other corporation) or (iv) the acquisition of the beneficial ownership of more
than 35% of the outstanding common stock of the Company by any person or group
(as defined under the Securities Exchange Act of 1934, as amended).


                                  CERTIFICATION

        The undersigned certifies that (i) he is the duly elected, qualified and
acting Vice President, Finance and Administration, Chief Financial Officer and
Secretary of International Remote Imaging Systems, Inc., a Delaware corporation,
and (ii) the foregoing is a true and correct copy of the Employee Stock Purchase
Plan as amended and restated by the Board of Directors at a meeting held on
October 31, 1999.

                                 AMENDMENT NO. 1

                                       TO

                            PATENT LICENSE AGREEMENT


        THIS AMENDMENT TO PATENT LICENSE AGREEMENT (this "Amendment") is dated
as of February 20, 2000 ("Effective Date") and is by and between International
Remote Imaging Systems, Inc., a Delaware corporation ("IRIS"), and Sysmex
Corporation, a Japanese corporation ("SYSMEX") formerly named TOA Medical
Electronics Co., Ltd., ("TOA"), with respect to the following facts:

        A. IRIS and TOA entered into that certain Patent License Agreement dated
as of April 1, 1997 (the "Patent License Agreement"), pursuant to which IRIS
licensed to TOA certain IRIS' patents for use by TOA in the development,
manufacturing, marketing, distribution and sale, on a commercial basis, of
instruments for non-medical, industrial applications in Japan and for certain
Japanese customers outside of Japan.

        B. IRIS now desires to license to SYSMEX, and SYSMEX now desires to
license from IRIS, such patents for use worldwide, subject to the terms and
conditions of the Patent License Agreement, as amended by this Amendment No. 1.

        NOW, THEREFORE, in consideration of the mutual covenants, promises,
agreements set forth in this Amendment, and for other good valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties amend the Patent License Agreement as follows. Unless otherwise stated,
all capitalized terms shall have the same meanings assigned to them in the
Patent License Agreement.

        1. Section 2 of the Patent License Agreement shall be renumbered as
Section 2(a).

        2. The following shall be added as Section 2(b) of the Patent License
Agreement:

               "In consideration of the payments by TOA to IRIS pursuant to
Sections 5.1, IRIS hereby grants to TOA for the Term a non-exclusive right and
license under the IRIS Patents to practice inventions covered by the IRIS
Patents to make Sales of Industrial Products worldwide, other than Sales as to
which a license is granted pursuant to Section 2(a) herein. Sales of Industrial
Products may be made directly by TOA or indirectly through a distributor or
agent of TOA. IRIS represents and warrants that it owns or holds rights to the
IRIS Patents necessary to grant the rights conveyed hereunder, and that the
exercise of such rights by TOA as contemplated hereunder will not conflict with,
infringe or otherwise violate the rights of third parties. This representation
is not intended to cover compliance with United States export laws affecting the
transfer of IRIS Patents, compliance with which TOA assumes responsibility."

        3. Section 5.1(b) of Patent License Agreement shall be amended to read
as follows:

               "b. Periodic Payment.

                      (i) With respect to the license granted under Section
2(a), not later than thirty (30) days following the end of each calendar quarter
throughout the Term, TOA shall pay to IRIS in immediately available funds in US
Dollars royalties in the amount of five percent (5%) of Revenues received by TOA
or its subsidiaries from sales of Industrial Products and Associated Consumable
and Spare Parts during such completed calendar quarter (the "Periodic
Payments"), net of payments made pursuant to Sections 5.1(c)(i).

                      (ii) With respect to the license granted under Section
2(b), not later than thirty (30) days following the end of such calendar quarter
throughout the Term, TOA shall pay to IRIS in

immediately available funds in US Dollars royalties in the amount of five
percent (5%) of Revenues received by TOA or its subsidiaries from Sales of
Industrial Products and Associated Consumable and Spare Parts during such
completed calendar quarter (the "Periodic Payments"), net of payments made
pursuant to Sections 5.1(c)(ii).

        4. Section 5.1(c) of the Patent License Agreement shall be amended to
read as follows:

               "c. Minimum Payments.

                      (i) With respect to the license granted under Section
2(a), for each of the three (3) 12-month periods commencing July 1, 1998, July
1, 1999 and July 1, 2000 only, TOA shall make minimum payments to IRIS in the
amount of Fifty Thousand US Dollars (US$50,000). Each such minimum payment shall
be payable at the commencement of each such twelve-month (12-month) period and
shall be credited against the payment of Periodic Payments due in respect to
Revenues received by TOA with respect to the license granted under Section 2(a)
during such 12-month period."

                      (ii) With respect to the license granted under Section
2(b), for each of the four (4) 12-month periods commencing July 1, 2000, July 1,

payment shall be payable at the commencement of each such twelve-month
(12-month) period and shall be credited against the payment of Periodic Payments

        2. Exercise. Each Warrant shall entitle the Holder to purchase one

made from time to time as provided herein) upon the exercise thereof during the
Exercise Period at the Exercise Price; provided, however, that the Warrants are
exercisable only for whole shares and cash will be paid in lieu of fractional
shares in accordance with Section 4.3.

        3. Form of Warrant Certificate. All certificates representing the
Warrants ("WARRANT CERTIFICATES"), which may hereinafter be issued and the forms
of election to purchase shares to accompany such Warrant Certificates shall be

        4. Duration and Exercise of Warrants.

               4.1 (a) Exercise Period. The Warrants may be exercised at any
time or from time to time during the Exercise Period. Upon the Expiration Date,
all rights evidenced by the Warrants shall cease and the Warrants shall become

                      (b) Manner of Exercise. Subject to the provisions of this
Warrant Certificate, the Holder shall have the right to purchase from the
Company (and the Company shall issue and sell to the Holder) the number of fully

such number of Warrant Shares as may result from adjustments made from time to
time as provided in this Warrant Certificate), at the Exercise Price, upon (i)
surrender of the Warrant Certificate to the Company at its principal office
located at 9162 Eton Avenue, Chatsworth, California 91311 with the exercise form
attached hereto duly completed and signed by the Holder or by a duly appointed

<PAGE>   3

representative thereof or by a duly authorized attorney and (ii) payment in cash
or in certified or official bank check payable to the order of the Company of

such Warrant is then exercised. Upon surrender of a Warrant Certificate, and
payment of the Exercise Price, the Company shall issue and cause to be delivered
with all reasonable dispatch to or upon the written order of the Holder and in
such name or names as Holder may designate, a certificate or certificates for
the number of Warrant Shares so purchased upon the exercise of such Warrant,
together with cash in respect of any fraction of a Warrant Share issuable upon
such surrender.

               4.2 Unexercised Portion. In the event that less than all of the
Warrants represented by this Warrant Certificate are exercised before 5:00 p.m.,
Los Angeles time, on the Expiration Date, a new Warrant Certificate, duly
executed by the Company, will be issued for the remaining number of Warrants
exercisable pursuant to the Warrant Certificate so surrendered.

               4.3 No Fractional Shares. Warrants may not be exercised for a
fraction of a share. In lieu of issuing fractional shares, the Company will pay
an amount in cash equal to that fractional interest of the then current Closing
Price per share of Common Stock.

               4.4 Adjustments. The number of Warrant Shares to be received upon
the exercise of a Warrant is subject to adjustment from time to time as
hereinafter set forth.

        5. Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the original issuance of the Warrants and of the shares of
Common Stock issuable upon the exercise of Warrants; provided, however, that the
Company shall not be required to (a) pay any tax which may be payable in respect
to any transfer involved in the transfer and delivery of Warrant Certificates or
the issuance or delivery of certificates for Warrant Shares in a name other than
that of the Holder upon the exercise of a Warrant or (b) issue or deliver any
certificate for Warrant Shares upon the exercise of any Warrants until any such
tax required to be paid under clause (a) shall have been paid, all such tax
being payable by the Holder at the time of surrender.

        6. Mutilated or Missing Warrants. In case any Warrant Certificate shall
be mutilated, lost, stolen or destroyed, the Company shall issue and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant
Certificate, or in lieu of a substitution for the lost, stolen or destroyed
Warrant Certificate, a new Warrant Certificate of like tenor and evidencing the
number of Warrant Shares purchasable upon exercise of the Warrant Certificate so
mutilated, lost, stolen or destroyed, but only upon receipt of evidence
satisfactory to Company of such loss, theft or destruction of such Warrant
Certificate and indemnity, if requested, also satisfactory to it. Applicants for
such substitute Warrant Certificate shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.
Any such new Warrant Certificate shall constitute an original contractual
obligation of the Company, whether or not the allegedly lost, stolen, mutilated
or destroyed Warrant Certificate shall be at any time enforceable by anyone.

        7. Reservation of Warrant Shares; Stock Certificates. The Company shall
at all times reserve for issuance and delivery upon exercise of the Warrants,
such number of Warrant Shares or other shares of capital stock of the Company
from time to time issuable upon exercise of the Warrants. All such shares shall
be duly authorized and, when issued upon such exercise, shall be validly issued,
fully paid and nonassessable, free and clear of all liens, security interests,
charges and other encumbrances or restrictions on sale and free and clear of all
preemptive rights.

        8. Registration of Warrants and Warrant Shares.

               8.1 Unregistered Status of Warrants and Warrant Shares. Neither
the Warrants nor the Warrant Shares have been registered under the Securities
Act of 1933, as amended (the "SECURITIES ACT"), or qualified under applicable
state securities laws and may not be transferred, sold, assigned, pledged or
otherwise disposed of unless (i) a registration statement under the Securities
Act shall have become effective with respect thereto and all applicable
qualifications under state securities laws shall have been obtained with respect
thereto or (ii) a written opinion from counsel for the Holder reasonably



                                       11
<PAGE>   4

satisfactory to the Company has been obtained stating that no such registration
or qualification is required.

                      8.2 Registration Rights. The Holder is entitled to certain
registration rights from the Company as set forth in the Registration Rights and
Standstill Agreement.

        9. Exchange, Transfer or Assignment of Warrant. Warrants may not be
transferred, sold, assigned, pledged or otherwise disposed of unless and until
IRIS receives from the transferee, buyer, assignee, pledgee or other recipient
(and from such person's spouse, if applicable) a written consent to be bound by
all of the terms and conditions of the Registration Rights and Standstill
Agreement. Subject to the preceding sentence and Section 8.1, Warrants may be
assigned or transferred, at the option of the Holder, upon surrender of Warrant
Certificates to the Company, accompanied (if so required by the Company) by a
written instrument or instruments of transfer in form satisfactory to the
Company, duly executed by the registered Holder or by a duly authorized
representative or attorney. Upon any such registration of transfer, a new
Warrant Certificate shall be issued to the transferee and the surrendered
Warrant Certificate shall be canceled by the Company. Any new Warrant or
Warrants issued pursuant to this Section 9 shall be dated as of the date of
issuance by the Company.

        10. Rights of Warrant Certificate Holder. The Holder shall not, by
virtue of being the holder of any Warrant Certificate or Warrants, be entitled
to any rights of a stockholder of the Company, either at law or in equity, and
the rights of the Holder are limited to those expressed in this Warrant
Certificate.

        11. Antidilution Provisions. The Exercise Price, the number of Warrant
Shares that may be purchased upon the exercise of a Warrant and the number of
Warrants outstanding will be subject to change or adjustment as follows:

               11.1 Stock Dividends and Stock Splits. If at any time after the
date of the issuance of the Warrants and before 5:00 p.m., Los Angeles, time, on
the Expiration Date, (i) the Company shall fix a record date for the issuance of
any stock dividend payable in shares of Common Stock or (ii) the number of
shares of Common Stock shall have been increased by a subdivision or split-up of
shares of Common Stock, then, on the record date fixed for the determination of
holders of Common Stock entitled to receive such dividend or immediately after
the effective date of such subdivision or split-up, as the case may be, the
number of shares to be delivered upon exercise of any Warrant will be
appropriately increased so that the Holder thereafter will be entitled to
receive the number of shares of Common Stock that the Holder would have owned
immediately following such action had the Warrant been exercised immediately
prior thereto, and the Exercise Price will be appropriately adjusted. The time
of occurrence of an event giving rise to an adjustment made pursuant to this
Section 11.1 shall, in the case of a subdivision, combination or
reclassification, be the effective date thereof and shall, in the case of a
dividend or distribution, be the record date thereof.

               11.2 Combination of Stock. If the number of shares of Common
Stock outstanding at any time after the date of the issuance of the Warrants and
before 5:00 p.m., Los Angeles time, on the Expiration Date shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of any Warrant will be
appropriately decreased so that the Holder thereafter will be entitled to
receive the number of shares of Common Stock that the Holder would have owned
immediately following such action had the Warrant been exercised immediately
prior thereto, and the Exercise Price will be appropriately adjusted.

               11.3 Reorganization. If any capital reorganization of the
Company, or any reclassification of the Common Stock, or any consolidation of
the Company with or merger of the Company with or into any other corporation or
any sale, lease or other transfer of all or substantially all of the assets of
the Company to any other person (including any individual, partnership, joint
venture, corporation, trust or group thereof), shall be effected in such a way
that the holders of the Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Stock, then, upon
exercise of the Warrant Certificate, the Holder shall have the right to receive
the kind and



                                       12
<PAGE>   5

amount of stock, securities or assets receivable upon such reorganization,
reclassification, consolidation, merger or sale, lease or other transfer by a
holder of the number of shares of Common Stock that the Holder would have been
entitled to receive upon exercise of the Warrants had the Warrants been
exercised immediately before such reorganization, reclassification,
consolidation, merger or sale, lease or other transfer, subject to adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 11.

               11.4 Record Date Adjustments. In any case in which this Section
11 requires that a downward adjustment of the Exercise Price shall become
effective immediately after a record date for an event, the Company may defer
until the occurrence of such event (A) issuing to the Holder exercised after
such record date and before the occurrence of such event the additional Warrant
Shares issuable upon such exercise by reason of the adjustment required by such
event over and above the Warrant Shares issuable upon such exercise before
giving effect to such adjustment and (B) paying to the Holder any amount in cash
in lieu of a fractional share pursuant to Section 4.3 hereof.

               11.5 Notice of Adjustment. Upon the occurrence of any event which
requires any adjustment of the Exercise Price and/or the number of Warrant
Shares that may be issued, then and in each such case the Company shall give
notice thereof to the Holder, which notice shall state the Exercise Price and
number of shares purchasable after giving effect to such adjustment, setting
forth in reasonable detail the method of calculation and the facts upon which
such calculated is based.

               11.6 Special Dividends. If (other than in a dissolution or
liquidation) securities of the Company (other than shares of Common Stock or
securities issued pursuant to a shareholder rights plan or any similar plan) or
assets (other than cash dividends payable out of retained earnings or out of any
amount legally available for dividends under the laws of the State of Delaware)
are issued by way of a dividend on outstanding shares of Common Stock, then the
Exercise Price shall be adjusted so that it shall equal the price determined by
multiplying the Exercise Price in effect immediately prior to the close of
business on the record date for the determination of the stockholders entitled
to receive such dividend by a fraction, the numerator of which shall be the
Closing Price on such record date less the then fair market value as determined
by the Board of Directors of the Company, whose determination shall be
conclusive, of the portion of the securities or assets distributed applicable to
one share of Common Stock and the denominator of which shall be such Closing
Price. Such adjustment shall become effective immediately prior to the opening
of business on the day following such record date.

               11.7 No Adjustments to Exercise Price. No adjustments in the
Exercise Price in accordance with the provisions of this Section 11 need be made
if such adjustment would amount to a change in the Exercise Price of less than
$.01; provided, however, that the amount by which any adjustment is not made by
reason of the provision of this Section shall be carried forward and taken into
account at the time of any subsequent adjustment in the Exercise Price.

               11.8 Readjustments, etc. If an adjustment is made pursuant to
this Section 11, and the event to which the adjustment relates does not occur,
then any adjustments in the Exercise Price or number of Warrant Shares that were
made in accordance with such paragraphs shall be adjusted back to the Exercise
Price and the number of Warrant Shares that were in effect immediately prior to
the record date for such event. In any case in which an adjustment is required
pursuant to this Section 11 as of the record date for a specified event, the
Company may elect to defer until the occurrence of such event the issuing to the
holder of any Warrant exercised after such record date the shares of Common
Stock and other securities, if any, issuable upon such exercise over and above
the shares of Common Stock and other securities, if any, issuable upon such
exercise on the basis of the Exercise Price in effect prior to such adjustment;
provided, however, that the Company shall deliver to such holder a due bill or
other appropriate instrument evidencing such holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

        12. Officer's Certificate. Whenever the number of Warrant Shares that
may be purchased upon exercise of the Warrants or the Exercise Price is adjusted
as required by the provisions of this Warrant Certificate, the Company will
forthwith file in the custody of its Secretary or an Assistant



                                       13
<PAGE>   6

Secretary at its principal office an officer's certificate showing the adjusted
number of Warrant Shares that may be purchased upon exercise of the Warrants and
the adjusted Exercise Price, determined as herein provided, setting forth in
reasonable detail the facts requiring such adjustment and the manner of
computing such adjustment. Each such officer's certificate shall be made
available at all reasonable times for inspection by any registered holder of a
Warrant Certificate. The Company shall, forthwith after such adjustment, cause a
copy of such certificate to be mailed to each registered holder of a Warrant
Certificate at the time of such mailing. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of any action referred
to in Section 11 hereof.

        13. Notice of Certain Events.

               13.1 At any time during the Exercise Period, in the event:

                      13.1.1 the Company authorizes the distribution to all
holders of the Common Stock of evidences of its indebtedness or assets (other
than cash dividends payable out of retained earnings or out of amounts legally
available for distribution under the laws of the State of Delaware or stock
dividends or securities issued pursuant to a shareholders rights plan or any
similar plan); or

                      13.1.2 of any capital reorganization or reclassification
of the Common Stock (other than a subdivision or combination of the outstanding
Common Stock and other than a change in par value of the Common Stock), or any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company is required (other than a consolidation or
merger in which the Company is the continuing corporation and that does not
result in any reclassification or change in the outstanding Common Stock) or of
the sale, lease or other transfer of all or substantially all of the assets of
the Company; or

                      13.1.3 of the voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then the Company will cause to be mailed to the Holder, at least 20 days before
the applicable record or effective date hereinafter specified, a notice stating
(A) the date as of which the holders of Common Stock of record entitled to
receive any such rights, warrants or distributions are to be determined or (B)
the date on which any such consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding-up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record will be
entitled to exchange their shares of Common Stock for securities or other

winding-up.

adversely affect the interests of the Holder.

                            VOID AFTER JULY 31, 2001



        This certifies that, for value received, Anthony G. Landells, an

exercised at any time or from time to time on or after the date hereof and will

exchange, on the NASDAQ National Market System or, if not listed or traded on
any such exchange or system, the mean of the closing bid and asked prices per
share on NASDAQ or, if such quotations are not available, the fair market value
as reasonably determined by the Board of Directors of the Company or any
committee of such Board.

               1.2 "COMMON STOCK" means (i) the class of stock designated as the
common stock, $.01 par value per share, of the Company on the date hereof or
(ii) any other class of stock resulting from successive changes or
reclassifications of such shares consisting solely of changes in par value, or
from par value to no par value, or from no par value to par value. Unless the
context requires otherwise, all references to Common Stock and Warrant Shares in
this Warrant Certificate shall, in the event of an adjustment pursuant to

then issuable upon exercise of the Warrants as a result of such adjustment.

               1.3 "EXERCISE PERIOD" shall mean the period from the date hereof
to 5:00 p.m., Los Angeles time on the Expiration Date.

               1.4 "EXERCISE PRICE" means Three Dollars and Fifty-Six Cents
($3.56) per share of Common Stock, as adjusted from time to time pursuant to
Section 11.

               1.5 "EXPIRATION DATE" means July 31, 2001, or if such date shall
be a holiday or a day on which banks are authorized to close, then the next
following date which is neither a holiday or a day on which banks are authorized
to close.

               1.6 "REGISTRATION RIGHTS AND STANDSTILL AGREEMENT" means the
Registration Rights and Standstill Agreement dated as of even date herewith
between the Company and Landells.

        2. Exercise. Each Warrant shall entitle the Holder to purchase one
Warrant Share (or such number of Warrant Shares as may result from adjustments
made from time to time as provided herein) upon the exercise thereof during the
Exercise Period at the Exercise Price; provided, however, that the Warrants are
exercisable only for whole shares and cash will be paid in lieu of fractional
shares in accordance with Section 4.3.

        3. Form of Warrant Certificate. All certificates representing the
Warrants ("WARRANT CERTIFICATES"), which may hereinafter be issued and the forms
of election to purchase shares to accompany such Warrant Certificates shall be
substantially in the form of this Warrant Certificate and may have such letters,
numbers or other marks of identification or designation and such legends
(including, without limitation, a legend referring to restrictions on resale by
statutory underwriters), summaries or endorsements printed thereon as the
Company may deem appropriate and as are not inconsistent with the provisions of
this Warrant Certificate, or as may be required to comply with any law or with
any rule or regulation made pursuant thereto or with any rule or regulation of
the National Association of Securities Dealers Automated Quotation System
("NASDAQ"), the NASDAQ National Market System or any stock exchange on which the
Warrants may from time to time be listed. All Warrant Certificates shall be
executed on behalf of the Company by its President or any Vice President.
Warrants shall be dated as of the date of issuance either upon their initial
issuance or transfer by the Company.

        4. Duration and Exercise of Warrants.

               4.1 (a) Exercise Period. The Warrants may be exercised at any
time or from time to time during the Exercise Period. Upon the Expiration Date,
all rights evidenced by the Warrants shall cease and the Warrants shall become
void.

                      (b) Manner of Exercise. Subject to the provisions of this
Warrant Certificate, the Holder shall have the right to purchase from the
Company (and the Company shall issue and sell to the Holder) the number of fully
paid and nonassessable Warrant Shares set forth on this Warrant Certificate (or
such number of Warrant Shares as may result from adjustments made from time to
time as provided in this Warrant Certificate), at the Exercise Price, upon (i)
surrender of the Warrant Certificate to the Company at its principal office
located at 9162 Eton Avenue, Chatsworth, California 91311 with the exercise form
attached hereto duly completed and signed by the Holder or by a duly appointed
legal representative thereof or by a duly authorized attorney and (ii) payment
in cash or in certified or official bank check payable to the order of the
Company of the Exercise Price for the Warrant Share or Warrant Shares in respect
of which such Warrant is then exercised. Upon surrender of a Warrant
Certificate, and



                                       20
<PAGE>   13

payment of the Exercise Price, the Company shall issue and cause to be delivered
with all reasonable dispatch to or upon the written order of the Holder and in
such name or names as Holder may designate, a certificate or certificates for
the number of Warrant Shares so purchased upon the exercise of such Warrant,
together with cash in respect of any fraction of a Warrant Share issuable upon
such surrender.

               4.2 Unexercised Portion. In the event that less than all of the
Warrants represented by this Warrant Certificate are exercised before 5:00 p.m.,
Los Angeles time, on the Expiration Date, a new Warrant Certificate, duly
executed by the Company, will be issued for the remaining number of Warrants
exercisable pursuant to the Warrant Certificate so surrendered.

               4.3 No Fractional Shares. Warrants may not be exercised for a
fraction of a share. In lieu of issuing fractional shares, the Company will pay
an amount in cash equal to that fractional interest of the then current Closing
Price per share of Common Stock.

               4.4 Adjustments. The number of Warrant Shares to be received upon
the exercise of a Warrant is subject to adjustment from time to time as
hereinafter set forth.

        5. Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the original issuance of the Warrants and of the shares of
Common Stock issuable upon the exercise of Warrants; provided, however, that the
Company shall not be required to (a) pay any tax which may be payable in respect
to any transfer involved in the transfer and delivery of Warrant Certificates or
the issuance or delivery of certificates for Warrant Shares in a name other than
that of the Holder upon the exercise of a Warrant or (b) issue or deliver any
certificate for Warrant Shares upon the exercise of any Warrants until any such
tax required to be paid under clause (a) shall have been paid, all such tax
being payable by the Holder at the time of surrender.

        6. Mutilated or Missing Warrants. In case any Warrant Certificate shall
be mutilated, lost, stolen or destroyed, the Company shall issue and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant
Certificate, or in lieu of a substitution for the lost, stolen or destroyed
Warrant Certificate, a new Warrant Certificate of like tenor and evidencing the
number of Warrant Shares purchasable upon exercise of the Warrant Certificate so
mutilated, lost, stolen or destroyed, but only upon receipt of evidence
satisfactory to Company of such loss, theft or destruction of such Warrant
Certificate and indemnity, if requested, also satisfactory to it. Applicants for
such substitute Warrant Certificate shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.
Any such new Warrant Certificate shall constitute an original contractual
obligation of the Company, whether or not the allegedly lost, stolen, mutilated
or destroyed Warrant Certificate shall be at any time enforceable by anyone.

        7. Reservation of Warrant Shares; Stock Certificates. The Company shall
at all times reserve for issuance and delivery upon exercise of the Warrants,
such number of Warrant Shares or other shares of capital stock of the Company
from time to time issuable upon exercise of the Warrants. All such shares shall
be duly authorized and, when issued upon such exercise, shall be validly issued,
fully paid and nonassessable, free and clear of all liens, security interests,
charges and other encumbrances or restrictions on sale and free and clear of all
preemptive rights.

        8. Registration of Warrants and Warrant Shares.

               8.1 Unregistered Status of Warrants and Warrant Shares. Neither
the Warrants nor the Warrant Shares have been registered under the Securities
Act of 1933, as amended (the "SECURITIES ACT"), or qualified under applicable
state securities laws and may not be transferred, sold, assigned, pledged or
otherwise disposed of unless (i) a registration statement under the Securities
Act shall have become effective with respect thereto and all applicable
qualifications under state securities laws shall have been obtained with respect
thereto or (ii) a written opinion from counsel for the Holder reasonably
satisfactory to the Company has been obtained stating that no such registration
or qualification is required.



                                       21
<PAGE>   14

               8.2 Registration Rights. The Holder is entitled to certain
registration rights from the Company as set forth in the Registration Rights and
Standstill Agreement.

        9. Exchange, Transfer or Assignment of Warrant. Warrants may not be
transferred, sold, assigned, pledged or otherwise disposed of unless and until
IRIS receives from the transferee, buyer, assignee, pledgee or other recipient
(and from such person's spouse, if applicable) a written consent to be bound by
all of the terms and conditions of the Registration Rights and Standstill
Agreement. Subject to the preceding sentence and Section 8.1, Warrants may be
assigned or transferred, at the option of the Holder, upon surrender of Warrant
Certificates to the Company, accompanied (if so required by the Company) by a
written instrument or instruments of transfer in form satisfactory to the
Company, duly executed by the registered Holder or by a duly authorized
representative or attorney. Upon any such registration of transfer, a new
Warrant Certificate shall be issued to the transferee and the surrendered
Warrant Certificate shall be canceled by the Company. Any new Warrant or
Warrants issued pursuant to this Section 9 shall be dated as of the date of
issuance by the Company.

        10. Rights of Warrant Certificate Holder. The Holder shall not, by
virtue of being the holder of any Warrant Certificate or Warrants, be entitled
to any rights of a stockholder of the Company, either at law or in equity, and
the rights of the Holder are limited to those expressed in this Warrant
Certificate.

        11. Antidilution Provisions. The Exercise Price, the number of Warrant
Shares that may be purchased upon the exercise of a Warrant and the number of
Warrants outstanding will be subject to change or adjustment as follows:

               11.1 Stock Dividends and Stock Splits. If at any time after the
date of the issuance of the Warrants and before 5:00 p.m., Los Angeles, time, on
the Expiration Date, (i) the Company shall fix a record date for the issuance of
any stock dividend payable in shares of Common Stock or (ii) the number of
shares of Common Stock shall have been increased by a subdivision or split-up of
shares of Common Stock, then, on the record date fixed for the determination of
holders of Common Stock entitled to receive such dividend or immediately after
the effective date of such subdivision or split-up, as the case may be, the
number of shares to be delivered upon exercise of any Warrant will be
appropriately increased so that the Holder thereafter will be entitled to
receive the number of shares of Common Stock that the Holder would have owned
immediately following such action had the Warrant been exercised immediately
prior thereto, and the Exercise Price will be appropriately adjusted. The time
of occurrence of an event giving rise to an adjustment made pursuant to this
Section 11.1 shall, in the case of a subdivision, combination or
reclassification, be the effective date thereof and shall, in the case of a
dividend or distribution, be the record date thereof.

               11.2 Combination of Stock. If the number of shares of Common
Stock outstanding at any time after the date of the issuance of the Warrants and
before 5:00 p.m., Los Angeles time, on the Expiration Date shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of any Warrant will be
appropriately decreased so that the Holder thereafter will be entitled to
receive the number of shares of Common Stock that the Holder would have owned
immediately following such action had the Warrant been exercised immediately
prior thereto, and the Exercise Price will be appropriately adjusted.

               11.3 Reorganization. If any capital reorganization of the
Company, or any reclassification of the Common Stock, or any consolidation of
the Company with or merger of the Company with or into any other corporation or
any sale, lease or other transfer of all or substantially all of the assets of
the Company to any other person (including any individual, partnership, joint
venture, corporation, trust or group thereof), shall be effected in such a way
that the holders of the Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Stock, then, upon
exercise of the Warrant Certificate, the Holder shall have the right to receive
the kind and amount of stock, securities or assets receivable upon such
reorganization, reclassification, consolidation, merger or sale, lease or other
transfer by a holder of the number of shares of Common Stock that the Holder
would have been entitled to receive upon exercise of the Warrants had the
Warrants been



                                       22
<PAGE>   15

exercised immediately before such reorganization, reclassification,
consolidation, merger or sale, lease or other transfer, subject to adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 11.

               11.4 Record Date Adjustments. In any case in which this Section
11 requires that a downward adjustment of the Exercise Price shall become
effective immediately after a record date for an event, the Company may defer
until the occurrence of such event (A) issuing to the Holder exercised after
such record date and before the occurrence of such event the additional Warrant
Shares issuable upon such exercise by reason of the adjustment required by such
event over and above the Warrant Shares issuable upon such exercise before
giving effect to such adjustment and (B) paying to the Holder any amount in cash
in lieu of a fractional share pursuant to Section 4.3 hereof.

               11.5 Notice of Adjustment. Upon the occurrence of any event which
requires any adjustment of the Exercise Price and/or the number of Warrant
Shares that may be issued, then and in each such case the Company shall give
notice thereof to the Holder, which notice shall state the Exercise Price and
number of shares purchasable after giving effect to such adjustment, setting
forth in reasonable detail the method of calculation and the facts upon which
such calculated is based.

               11.6 Special Dividends. If (other than in a dissolution or
liquidation) securities of the Company (other than shares of Common Stock or
securities issued pursuant to a shareholder rights plan or any similar plan) or
assets (other than cash dividends payable out of retained earnings or out of any
amount legally available for dividends under the laws of the State of Delaware)
are issued by way of a dividend on outstanding shares of Common Stock, then the
Exercise Price shall be adjusted so that it shall equal the price determined by
multiplying the Exercise Price in effect immediately prior to the close of
business on the record date for the determination of the stockholders entitled
to receive such dividend by a fraction, the numerator of which shall be the
Closing Price on such record date less the then fair market value as determined
by the Board of Directors of the Company, whose determination shall be
conclusive, of the portion of the securities or assets distributed applicable to
one share of Common Stock and the denominator of which shall be such Closing
Price. Such adjustment shall become effective immediately prior to the opening
of business on the day following such record date.

               11.7 No Adjustments to Exercise Price. No adjustments in the
Exercise Price in accordance with the provisions of this Section 11 need be made
if such adjustment would amount to a change in the Exercise Price of less than
$.01; provided, however, that the amount by which any adjustment is not made by
reason of the provision of this Section shall be carried forward and taken into
account at the time of any subsequent adjustment in the Exercise Price.

               11.8 Readjustments, etc. If an adjustment is made pursuant to
this Section 11, and the event to which the adjustment relates does not occur,
then any adjustments in the Exercise Price or number of Warrant Shares that were
made in accordance with such paragraphs shall be adjusted back to the Exercise
Price and the number of Warrant Shares that were in effect immediately prior to
the record date for such event. In any case in which an adjustment is required
pursuant to this Section 11 as of the record date for a specified event, the
Company may elect to defer until the occurrence of such event the issuing to the
holder of any Warrant exercised after such record date the shares of Common
Stock and other securities, if any, issuable upon such exercise over and above
the shares of Common Stock and other securities, if any, issuable upon such
exercise on the basis of the Exercise Price in effect prior to such adjustment;
provided, however, that the Company shall deliver to such holder a due bill or
other appropriate instrument evidencing such holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

        12. Officer's Certificate. Whenever the number of Warrant Shares that
may be purchased upon exercise of the Warrants or the Exercise Price is adjusted
as required by the provisions of this Warrant Certificate, the Company will
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office an officer's certificate showing the adjusted number of Warrant
Shares that may be purchased upon exercise of the Warrants and the adjusted
Exercise Price, determined as herein provided, setting forth in reasonable
detail the facts requiring such adjustment and the manner of



                                       23
<PAGE>   16

computing such adjustment. Each such officer's certificate shall be made
available at all reasonable times for inspection by any registered holder of a
Warrant Certificate. The Company shall, forthwith after such adjustment, cause a
copy of such certificate to be mailed to each registered holder of a Warrant
Certificate at the time of such mailing. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of any action referred
to in Section 11 hereof.

        13. Notice of Certain Events.

               13.1 At any time during the Exercise Period, in the event:

                      13.1.1 the Company authorizes the distribution to all
holders of the Common Stock of evidences of its indebtedness or assets (other
than cash dividends payable out of retained earnings or out of amounts legally
available for distribution under the laws of the State of Delaware or stock
dividends or securities issued pursuant to a shareholders rights plan or any
similar plan); or

                      13.1.2 of any capital reorganization or reclassification
of the Common Stock (other than a subdivision or combination of the outstanding
Common Stock and other than a change in par value of the Common Stock), or any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company is required (other than a consolidation or
merger in which the Company is the continuing corporation and that does not
result in any reclassification or change in the outstanding Common Stock) or of
the sale, lease or other transfer of all or substantially all of the assets of
the Company; or

                      13.1.3 of the voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then the Company will cause to be mailed to the Holder, at least 20 days before
the applicable record or effective date hereinafter specified, a notice stating
(A) the date as of which the holders of Common Stock of record entitled to
receive any such rights, warrants or distributions are to be determined or (B)
the date on which any such consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding-up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record will be
entitled to exchange their shares of Common Stock for securities or other
property, if any, deliverable upon such reorganization, reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or
winding-up.

        14. Termination. This Warrant Certificate shall terminate at 5:00 p.m.,
Los Angeles time, on the earlier of (i) the Expiration Date or (ii) the date
upon which all Warrants have been exercised.

        15. Supplements and Amendments. The Company may from time to time
supplement or amend this Warrant Certificate without the approval of the Holder
in order to cure any ambiguity, to correct or supplement any provision contained
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions in regard to matters or questions arising
hereunder which the Company may deem necessary or desirable and which shall not
adversely affect the interests of the Holder.

        DISCLOSURE REGARDING RISK FACTORS AND FORWARD-LOOKING STATEMENTS

        This exhibit contains a discussion of various risk factors and other
information that should be carefully considered. The risks and uncertainties
described below are not the only ones that impact International Remote Imaging
Systems, Inc. Additional risks and uncertainties not presently known to us or
that we currently deem immaterial may also have an adverse impact on us. Among
other things, this exhibit contains forward-looking statements that are based on
certain assumptions about future risks and uncertainties. We believe that our
assumptions are reasonable. Nonetheless, it is likely that at least some of
these assumptions will not come true. Accordingly, our actual results will
probably differ from the outcomes contained in any forward-looking statements.
These differences could be material. Factors that could cause or contribute to
such differences include, among other things, those discussed below, as well as
those discussed elsewhere in our Annual Report on Form 10-K for the fiscal year
ended December 31, 1999, of which this exhibit forms a part.

WE HAVE A POTENTIAL FOR CONTINUING OPERATING LOSSES.

        We have incurred net losses for the past three years. There can be no
assurance that we will be able to restore annual profitability. Furthermore, as
of July 31, 2001, we will be obligated to repay all amounts due under an
outstanding subordinated note. We currently owe $7.0 million under that note. At
maturity, we may not be capable of repaying the note and may seek to refinance
this debt obligation. There can be no assurance that we will be able to repay
the amounts owing under the note or that we will be able to successfully
refinance this debt.

OUR SUCCESS DEPENDS LARGELY ON SALES OF HIGH-PRICED LABORATORY INSTRUMENTS.

        Historically, we derived most of our revenues from the sale of two
families of high-priced instruments - The Yellow IRIS urinalysis workstations
and the PowerGene genetic analyzers. We recently entered into a letter of intent
to sell Perceptive Scientific Instruments--a division which manufactures and
markets the PowerGene genetic analyzers--and have restated our financial
information to account for PSI as a discontinued operation. Our remaining
product line, The Yellow IRIS, has list prices ranging from $100,000 to $195,000
depending on model and configuration. Relatively modest declines in unit sales
or gross margins for this product line could diminish our revenues and profits.

WE RELY ON SOME SINGLE-SOURCE SUPPLIERS FOR KEY COMPONENTS OF OUR INSTRUMENTS,
AND IF ANY OF THESE SUPPLIERS DISCONTINUE PRODUCTION OF THESE COMPONENTS, OR WE
ARE UNABLE TO REPLACE UNAVAILABLE COMPONENTS, IT COULD HARM OUR BUSINESS.

        Certain key components of our instruments are manufactured by
single-source suppliers. For example, Roche Diagnostics is the sole source for
our proprietary CHEMSTRIP/IRIStrip urine test strips and related urine test
strip readers, both used in The Yellow IRIS Models 300 and 500. Any of our
single-source suppliers could encounter production problems. If any
single-source supplier has an interruption in its production or discontinues a
key component, the volume of our instrument sales could be diminished and could
harm our business, financial condition and operating results.

        We currently use a unique multi-band image processor in The Yellow Iris
family of workstations.  The manufacturer has discontinued production of this
processor, and we plan to transition to an off-the-shelf new microprocessor.
Our failure to successfully and timely transition to another microprocessor
could have a material and adverse affect on system sales.

        In the past, single-source suppliers have discontinued their production
of key components and we have successfully replaced those discontinued
components with satisfactorily replacements components. However, if we are
unable to replace unavailable components in the future, we are likely to
experience a decrease in instrument


<PAGE>   2

sales.

THE INTENSIFYING COMPETITION WE FACE FROM BOTH ESTABLISHED ENTITIES AND NEW
ENTRIES IN THE MARKET MAY ADVERSELY AFFECT OUR REVENUES AND PROFITABILITY.

        There are many companies with active research and development programs
both in and outside of the clinical laboratory imaging systems field. Many of
these companies have considerable experience in areas of competing interest to
us. Additionally, we cannot determine if other firms are conducting potentially
competitive research, which could result in the development and introduction of
products that are either comparable or superior to the products we sell.
Specifically, if a competitor introduces a new product that is comparable or
superior to any model of The Yellow IRIS, then our unit sales or gross margins
could be diminished. This in turn could have a material adverse effect on our
overall financial condition and operations. Further, new product introductions,
product enhancements and the use of other technologies by our competitors could
lead to a loss of market acceptance and cause a decline in sales or gross
margins.

OUR SUCCESS DEPENDS ON OUR ABILITY TO ATTRACT, RETAIN AND MOTIVATE MANAGEMENT
AND OTHER SKILLED EMPLOYEES.

        Our success depends in significant part upon the continued services of
key management and skilled personnel. Competition for qualified personnel is
intense and there are a limited number of people with knowledge of, and
experience in, our industry. We do not have employment agreements with most of
our key employees. However, we generally enter into agreements with our
employees regarding patents, confidentiality and related matters. We do not
maintain life insurance polices on our employees. Our loss of key personnel,
especially without advance notice, or our inability to hire or retain qualified
personnel, could have a material adverse effect on our instrument sales and our
ability to maintain our technological edge. We cannot guarantee that we will
continue to retain our key management and skilled personnel, or that we will be
able to attract, assimilate and retain other highly qualified personnel in the
future.

ANY FAILURE TO SUCCESSFULLY INTRODUCE OUR FUTURE PRODUCTS AND SYSTEMS INTO THE
MARKET COULD ADVERSELY AFFECT OUR BUSINESS.

        The commercial success of our future products and systems depends upon
their acceptance by the medical community. Our future product plans include
capital-intensive laboratory instruments. We believe that these products can
significantly reduce labor costs, improve precision and offer other distinctive
benefits to the medical research community. However, there is often market
resistance to products which require significant capital expenditures or which
eliminate jobs through automation. We can make no assurance that the market will
accept our future products and systems, or that sales of our future products and
systems will grow at the rates expected by our management.

IF WE FAIL TO MEET CHANGING DEMANDS OF TECHNOLOGY, WE MAY NOT CONTINUE TO BE
ABLE TO COMPETE SUCCESSFULLY WITH OUR COMPETITORS.

        The market for our products and systems is characterized by rapid
technological advances, changes in customer requirements, and frequent new
product introductions and enhancements. Our future success depends upon our
ability to introduce new products that keep pace with technological
developments, enhance current product lines and respond to evolving customer
requirements. Our failure to meet these demands could result in a loss of our
market share and competitiveness and could harm our revenues and results of
operations.

ANY FAILURE OR INABILITY TO PROTECT OUR TECHNOLOGY AND CONFIDENTIAL INFORMATION
COULD ADVERSELY AFFECT OUR BUSINESS.

        PATENTS. Our commercial success depends in part on our ability to
protect and maintain our automated intelligent microscopy (or AIM) and other
proprietary technology. We have received patents with respect to portions of the
technologies of AIM. However, ownership of technology patents may not insulate
us from potentially damaging competition. Patent litigation relating to clinical
laboratory instrumentation patents (like the ones we own) often involve complex
legal and factual questions. Therefore, we can make no assurance that claims
under patents



<PAGE>   3

currently held by us, or our pending or future patent applications, will be
sufficiently broad to adequately protect what we believe to be our proprietary
rights. Additionally, one or more of our patents could be circumvented by a
competitor. We believe that our proprietary rights do not infringe upon the
proprietary rights of third parties. However, third parties may assert
infringement claims against us in the future. If we are unsuccessful in our
defense against any infringement claim our patents, or patents in which we have
licensed rights, may be held invalid and unenforceable.

        TRADE SECRETS. We have trade secrets, unpatented technology and
proprietary knowledge related to the sale, promotion, operation, development and
manufacturing of our products. We generally enter into confidentiality
agreements with our employees and consultants. However, we cannot guarantee that
our trade secrets, unpatented technology or proprietary knowledge will not
become known or be independently developed by competitors. If any of this
proprietary information becomes know to third parties, we may have no practical
recourse against these parties.

        COPYRIGHTS. We claim copyrights in our software and the ways in which it
assembles and displays images. We also claim trademark rights in the United
States and other foreign countries. However, we can make no assurance that we
will be able to obtain enforceable copyright and trademark protection, nor that
this protection will provide us a significant commercial advantage.

        POTENTIAL LITIGATION EXPENSES. Offensive or defensive litigation
regarding patent and other intellectual property rights could be time-consuming
and expensive. Additionally, litigation could demand significant attention from
our technical and management personnel. Any change in our ability to protect and
maintain our proprietary rights could materially and adversely affect our
financial condition and results of operations.

WE OPERATE IN A CONSOLIDATING INDUSTRY WHICH CREATES BARRIERS TO OUR MARKET
PENETRATION.

        The healthcare industry in recent years has been characterized by
consolidation. Large hospital chains and groups of affiliated hospitals prefer
to negotiate comprehensive supply contracts for all of their supply needs at
once. Large suppliers can often equip an entire laboratory and offer these
hospital chains and groups one-stop shopping for laboratory instruments,
supplies and service. Larger suppliers also typically offer annual rebates to
their customers based on the customer's total volume of business with the
supplier. The convenience and rebates offered by these large suppliers are
administrative and financial incentives that we do not offer our customers. Our
plans for further market penetration in the urinalysis market of The Yellow IRIS
family of workstations will depend in part on our ability to overcome these and
any new barriers resulting from continued consolidation in the healthcare
industry.

SINCE WE OPERATE IN THE MEDICAL TECHNOLOGY INDUSTRY, OUR PRODUCTS ARE SUBJECT TO
GOVERNMENT REGULATION THAT COULD IMPAIR OUR OPERATIONS.

        Most of our products are subject to stringent government regulation in
the United States and other countries. These regulatory processes can be
lengthy, expensive and uncertain. Additionally, securing necessary clearances or
approvals may require the submission of extensive official data and other
supporting information. Our failure to comply with applicable requirements could
result in fines, recall or seizure of products, total or partial suspension of
production, withdrawal of existing product approvals or clearances, refusal to
approve or clear new applications or notices, or criminal prosecution. If any of
these things occur, they could harm our business. Changes in existing federal,
state or foreign laws or regulations, or in the interpretation or enforcement of
these laws, could also materially and adversely affect our business.

CHANGES IN GOVERNMENT REGULATION OF THE HEALTHCARE INDUSTRY COULD ADVERSELY
AFFECT OUR BUSINESS.

        Federal and state legislative proposals are periodically introduced or
proposed that would affect major changes in the healthcare system, nationally,
at the state level or both. Future legislation, regulation or payment policies
of Medicare, Medicaid, private health insurance plans, health maintenance
organizations and other third-party payors could adversely affect the demand for
our current or future products and our ability to sell our products on a
profitable basis. Moreover, healthcare legislation is an area of extensive and
dynamic change, and we cannot predict future legislative changes in the
healthcare field or their impact on our industry or our business.

OUR NET OPERATING LOSS CARRYFORWARDS COULD BE REDUCED IF THERE IS A "CHANGE OF
OWNERSHIP" UNDER SECTION 382 OF THE INTERNAL REVENUE CODE.

        At December 31, 1999, we had federal net operating loss carryforwards of
approximately $17.5 million. Section 382 of the Internal Revenue Code imposes an
annual limitation on the utilization of net operating loss carryforwards based
on a statutory rate of return (usually the "applicable federal rate," as defined
in the Internal Revenue Code) and the value of the corporation at the time of a
"change of ownership" as defined by Section 382. If substantially all of our
outstanding options and warrants are exercised on or before December 31, 2000,
there will be a "change in ownership" under Section 382. Most of our currently
exercisable warrants and options are out-of-the-money, with exercise prices
ranging from $.[69 TO $7.80] per share. However, if the market price of our
common stock increases, a sufficient number selling stockholders may choose to
exercise their warrants and options. This may result in a change of ownership
under Section 382. If this set of circumstances occurs, the limitations imposed
by Section 382 could trigger a substantial write-down of our deferred tax assets
and a corresponding charge to our earnings in the relevant quarter.

WE ARE SUBJECT TO ANTI-TAKEOVER PROVISIONS IN OUR CHARTER THAT COULD DELAY OR
PREVENT AN ACQUISITION OF OUR COMPANY, EVEN IF SUCH AN ACQUISITION WOULD BE
BENEFICIAL TO OUR STOCKHOLDERS.

        Certain provisions of our certificate of incorporation, our bylaws and
Delaware law could, together or separately, delay or prevent a third party from
acquiring us, even if doing so might be beneficial to our stockholders. These
provisions may also limit the price that investors might be willing to pay for
shares of our common stock. Some of these provisions:

                -       establish a classified board of directors;

                -       authorize the issuance of preferred stock with rights
                        and privileges which could be senior to the common
                        stock, without prior stockholder approval;

                -       limit the right of stockholders to call a special
                        meeting of stockholders; and

                -       prohibit stockholder action by written consent.

        We also adopted a shareholders rights plan in December 1999.  The
rights are not presently exercisable.  They become exercisable only if a person
or group acquires 20% or more of our common stock, or announces a tender offer
for 20% or more of our common stock, without board approval.  If the rights are
triggered, all common stockholders (except the hostile party) will be entitled
to purchase shares of common stock (or the economic equivalent in preferred
stock) at a price based on a substantial discount from the market price of the
common stock.  The Board of Directors may terminate the plan at any time or
redeem the rights prior to their becoming exercisable.  The rights expire on
December 22, 2009.

        We also are subject to Section 203 of the Delaware General Corporation
Law which, subject to certain exceptions, prohibits a Delaware corporation from
engaging in any of a broad range of business combinations with any "interested
stockholder" for a period of three years following the date that such
stockholder became an interested stockholder.

DEFECTIVE PRODUCTS MAY SUBJECT US TO LIABILITY.

        Our products are used to gather information for medical decisions and
diagnosis. Accordingly, the manufacture and sale of our products entails an
inherent risk of product liability arising from an inaccurate, or allegedly
inaccurate, test result. We currently maintain product liability insurance
coverage for up to $1.0 million per incident and up to an aggregate of $2.0
million per year. We also currently maintain a product liability umbrella policy
for coverage of claims aggregating more than $5.0 million. Although management
believes this liability coverage is sufficient protection against future claims,
there can be no assurance of the sufficiency of these policies. We have not
received any indication that our insurance carrier will not renew our product
liability insurance at or near current premiums; however, we cannot guarantee
that this will continue to be the case. In addition, any failure to

comply with Federal Drug Administration regulations governing manufacturing
practices could hamper our ability to defend against product liability lawsuits.
