                                     PART I

Item 1.    BUSINESS.

         Criticare Systems, Inc. (the "Company" or "Criticare") designs,
manufactures and markets vital signs and gas monitoring instruments and related
noninvasive sensors used to monitor patients in many healthcare settings. Since
a patient's oxygen, anesthetic gas and carbon dioxide levels can change
dramatically within minutes, causing severe side effects or death, continuous
monitoring of these parameters is increasing. The Company's monitoring equipment
improves patient safety by delivering accurate, comprehensive and instantaneous
patient information to the clinician. The Company's products also allow
hospitals to contain costs primarily by substituting cost-effective reusable
pulse oximetry sensors for disposable sensors, controlling the use of costly
anesthetics and increasing personnel productivity.

         To meet the needs of end-users in a wide variety of patient settings,
the Company has developed a broad line of patient monitors which combine one or
more of its patented or other proprietary technologies, for monitoring oxygen
saturation, carbon dioxide and anesthetic agents, with standard monitoring
technologies that provide electrocardiogram ("ECG"), invasive and noninvasive
blood pressures, temperature, heart rate and respiration rate. In addition, the
Company's VitalView telemetry system allows one nurse to monitor up to eight
patients simultaneously from a convenient central location. This allows
hospitals to move out of the intensive care unit ("ICU") those patients that
require continuous monitoring, but do not need all of an ICU's extensive and
costly personnel and equipment resources.

         The Company was incorporated under the laws of the State of Delaware in
October 1984.

Products

         Criticare markets a broad range of vital signs and gas monitoring
products designed to address the needs of a variety of end-users in different
patient settings. Criticare's monitors display information graphically and
numerically. All Criticare monitors incorporate adjustable visual and audible
alarms to provide reliable patient-specific warnings of critical conditions, and
most of the Company's monitors record up to 60 hours of trend data. Criticare
monitors are available with printer capability to provide permanent records of
patient data.

         Model 503, 503S, 504, 504P, 504US, 504USP and 504O (PONI) Pulse
Oximeters. Criticare's complete line of pulse oximeters meets the needs of
virtually all clinical environments: adult, pediatric and neonatal intensive
care

                                       3
<PAGE>   4

units, operating rooms, emergency rooms, nursing homes, physicians' offices
and ambulances. The line is designed to provide accuracy and convenience at a
competitive cost to the end-user.

         Model 507S, 507SD, 507N, 507O and 507E Patient Monitors. The 507 series
is comprised of small, compact, portable, full-featured vital signs monitors
configured to meet specific clinical needs. The 507S and 507SD are well-suited
to dental and physician offices. The 507N and 507O are ideal for patient floor
monitoring of noninvasive blood pressure and pulse oximetry. The 507E combines
ECG, oxygen saturation and noninvasive blood pressure for a complete vital signs
monitor for physician office and hospital applications. Combined with the
VitalView central station, the 507E is an effective low-cost monitoring system
for the emergency room or the recovery room.

         Scholar(R). The Scholar monitor series specifically addresses the needs
of small hospitals with broad clinical needs (the monitoring of ECG, blood
oxygen saturation, noninvasive blood pressure, temperature and invasive blood
pressure) but whose budgets are small. Scholar offers all the primary features a
hospital needs with the capability of adding more features if desired. Scholar
monitors are available with printer and recorder capability and can transmit
data to Criticare's Maestro and VitalView Central Stations.

         Model 1100 Anesthesia Monitor. The Model 1100 monitor provides patient
monitoring for a wide variety of cardio-pulmonary parameters in an integrated
system. The Model 1100 is able to monitor two ECG waveforms, noninvasive blood
pressure, three types of invasive blood pressure, respiration rate, heart rate,
temperature, oxygen saturation, inspired/expired oxygen, carbon dioxide and the
range of anesthetic gases, including recently developed anesthetic agents such
as desflurane and sevoflurane. The Model 1100 uses the Company's proprietary
disposable respiratory secretion filter system and is designed to accommodate
low-flow anesthesia situations.

         Model 602-3B, 602-6B, 602-11 and 602-13 Gas Monitors. The 602 series
provides monitoring of carbon dioxide, pulse oximetry and anesthetic agents
using Criticare's proprietary infrared technology. The 602 IQ series of
operating room monitors provides automatic identification and quantification of
all five approved anesthetic agents simultaneously.

         Model 506DX Combination Monitor. The 506DX combination monitor was
developed in conjunction with Alaris Medical ("Alaris") and incorporates
Criticare's oximetry and noninvasive blood pressure technology with Alaris's
temperature technology. Alaris has rights to market the 506DX combination
monitor to hospitals in the United States and Canada. Criticare has rights to
market the product to the alternate care market and to international markets.


                                       4

         Model 820 Maestro(TM) I Telemetry Monitors. The Maestro I Telemetry
system addresses the rapidly expanding telemetry market with a reliable,
inexpensive ECG telemetry system. The Maestro I system provides a waterproof ECG
transmitter capable of five ECG lead configurations. The ability to link
Criticare's 507E and Scholar monitors to this versatile central station is
expected to expand the market into numerous hospital departments.

         VitalView(TM). The VitalView central station makes it possible for one
nurse or technician to monitor numerous patients simultaneously. The VitalView
can receive, display and store data from a wide variety of Criticare monitors
including the Scholar, 507E and MPT.

         MPT(TM). The MPT (Multiple Parameter Telemetry) monitor allows the
transmission of vital signs (ECG, blood oxygen saturation and noninvasive blood
pressure) on a real time basis to a VitalView central station while the patient
is ambulatory. The Company believes the MPT is the first device of its kind. In
today's healthcare environment, hospitals benefit by moving patients from
expensive critical care departments as quickly as possible to less expensive
general nursing floors. MPT, because of its complete monitoring capability and
its lower cost, allows the patient to be ambulatory while still being monitored
for all vital signs. MPT was approved by the FDA on December 10, 1996.

         Pulse Oximetry Sensors. Criticare has designed proprietary, noninvasive
sensors that can be used on any patient, from a premature infant to a full-grown
adult. Criticare's line of reusable pulse oximetry sensors offers users
significant cost savings compared to disposables. Criticare's reusable sensors
generally last longer than the one-year warranty period and are easily and
inexpensively cleaned between uses. Criticare's reusable sensors include a
finger sensor for routine applications and a multisite sensor for increased
placement flexibility. The multisite sensor is fully immersible, allowing for
sterilization between patients. Last year the Company introduced the "Shell"
sensor, the first reusable sensor with a removable hard cover. The cover can be
inexpensively replaced if it becomes damaged, saving hundreds of dollars over
buying a new sensor. The Shell sensor is also the first reusable sensor on the
market that can be fully dismantled and immersed for improved cleaning and
sterilization between patients if required. The Company also sells a range of
disposable sensors designed for single use in cases where the facility would
prefer to use a patient charge disposable product.

         Water Chek/Chek-Mate Filter System. The Company's patented, disposable
Water Chek system separates a patient's respiratory secretions from a breath
sample before it enters the gas monitor(s) for analysis. The Company's
proprietary, disposable Chek-Mate filter enhances the removal of moisture from
the sample, while preventing cross-contamination. This system allows the monitor

                                       5
<PAGE>   6

to operate effectively regardless of humidity or patient condition. The
self-sealing feature also protects the healthcare provider from potential
contamination.

Products Under Development

         Digital Oximetry DOT(TM). The Company is in the later stages of
developing two improved oxygen saturation monitors that incorporate a digital
electronic signal which allows more accurate saturation readings in conditions
influenced by light, motion or temperature artifact than the analog electronic
signal used in current oxygen saturation monitors.

         Vital Signs(TM). The Company is also in the later stages of developing
the hand-held Vital Signs monitor, which measures heart rate, oxygen saturation,
noninvasive blood pressure and temperature using a hand-held monitor weighing
less than two pounds. These features make the Vital Signs monitor well-suited
for use on nursing floors and in physicians' offices, ambulances and by home
healthcare organizations.

         Home View. The Company is in the active stage of developing a home care
application of the MPT (Multiple Parameter Telemetry) monitor and the VitalView
central station. When completed, the Home View system will allow patients to be
monitored, on a real time basis, using telephone modems to transmit data to the
care giver at a remote (hospital or home care) facility thereby further reducing
the cost of monitoring certain patients in the high cost hospital environment.

Marketing and Sales

         Domestic Sales. The Company's Systems Division focuses its efforts on
the MPT/VitalView Systems and related monitors such as Scholar I and Scholar II
that can interface with the VitalView Central Station. The flexibility of the
MPT Systems affords hospitals the opportunity to place monitoring where it is
used rather than being tied to fixed monitoring units. At August 31, 1998, the
Systems Division consisted of four sales specialists, five independent dealers,
three clinical specialists and one manager.

         The Company's Monitoring Division focuses its efforts on stand-alone
monitoring needs of hospitals, surgery centers, nursing homes and physician
offices. Monitoring Division products include pulse oximeters, CO2 monitors,
anesthetic agent monitors and vital signs monitors. At August 31, 1998, the
Monitoring Division consisted of four regional managers, approximately 60
independent dealers with approximately 600 sales people and one sales manager.

         International Sales. One of the Company's principal marketing
strategies has been to target international markets, particularly Europe, Latin
America and

                                       6

<PAGE>   7

the Pacific Rim countries. During fiscal 1998, Criticare sold its
products, principally to hospitals, in over 75 countries through over 140
independent dealers. During fiscal 1997, the Company's international sales
efforts were coordinated by the Company's wholly-owned subsidiary, Criticare
International GmbH Marketing Services, a corporation organized under the laws of
Germany ("Criticare International"). During fiscal 1998, Criticare International
was liquidated following bankruptcy proceedings under German law. Most of the
Company's international order processing, invoicing, collection and customer
service functions are handled directly from the Company's headquarters in
Waukesha, Wisconsin. However, the Company formed CSI Trading, Inc. during fiscal
1997 and Criticare Service GmbH during fiscal 1998 to perform certain marketing
and service functions in Europe. Criticare believes demand for the Company's
products in international markets is primarily driven by cost containment
concerns, and increased interest in using quality patient monitoring products
for improved patient management.

         In fiscal 1998, 46% of Criticare's net sales, or $12.8 million, was
attributable to international sales, of which approximately 43% was from sales
in Europe and the Middle East, 30% was from sales to Pacific Rim countries and
27% was from sales to Canada and Central and South America. In fiscal 1997, 51%
of Criticare's net sales was attributable to international sales. In fiscal
1996, 46% of Criticare's net sales was attributable to exports. There are no
material identifiable assets of the Company located in foreign markets. The
Company sells its products in United States dollars and is not subject to
significant currency risks; however, an increase in the value of the United
States dollar relative to foreign currencies could make the Company's products
less price competitive in those markets.

         Clinical Support. At August 31, 1998, Criticare employed three clinical
support specialists to provide customer training and education, primarily to
domestic hospitals. The clinical support staff also assists in the periodic
training and education of the direct sales force. In addition, the direct sales
force maintains contact with end-users and provides additional training and
updates. Clinical support in foreign markets is provided by the Company's
clinical support staff and direct sales force.

         Warranty and Service. Criticare believes that customer service is a key
element of its marketing program. Criticare's monitors are warranted against
defects for one year and its reusable sensors for six months. If a problem
develops with a Criticare product while under warranty, the Company typically
provides a replacement unit until the product can be repaired at the Company's
facility. At August 31, 1998, the Company had a customer service staff of 15
people at its Waukesha, Wisconsin facility. The Company also maintains a product
repair


                                       7
<PAGE>   8

facility in Bad Homburg, Germany for its international customers. The
Company offers extended warranties and service contracts on all of its monitors.

Manufacturing

         The Company continually strives to implement manufacturing efficiencies
while maintaining product quality and reliability. The Company's oximeters and
sensors are assembled from off-the-shelf components and other parts produced to
the Company's specifications, such as printed circuit board assemblies, custom
transformers and sensor cable/connector subassemblies. However, Criticare
produces certain important components in-house. All electronic components are
subjected to a 24-hour high-temperature burn-in to eliminate early component
failure. Some subassembly is performed by subcontractors, but final assembly and
quality control are performed at Criticare's facility. Criticare maintains test
and inspection procedures to minimize errors and enhance the operating
reliability of its products. Final test procedures on fully assembled units
include an operational test and a continuous 72-hour burn-in procedure.

         Certain of Criticare's products incorporate components currently
purchased from single sources. While the Company believes these components are
available from alternate sources on reasonable terms, an interruption in the
delivery of these or other components could have an adverse effect on the
Company. In order to reduce the risk of supply interruption, the Company
maintains inventories of certain components.

         The ISO 9000 series of quality management and assurance standards was
developed by the International Organization for Standardization (ISO) and
published in 1987. In 1993 the EC (European Community) was formed with the
signing of the Maastricht Treaty by 12 European countries. One of the many
standards adopted by this group is the ISO 9000 international quality assurance
and quality management series under the designation EN2 9000. Based on this
action by the EC and specific requirements from European customers, the Company
believes ISO 9000 registration will be required to compete in EC and other
international markets as an indication of compliance with international quality
management and assurance standards. In July 1994 the Food and Drug
Administration (FDA) announced its intention of harmonizing the ISO 9000
standards with its Medical Device Good Manufacturing Practices (GMP). The
Company has achieved certification under ISO's standards 9001 and 9002. See
"Regulation."

Research, Development and Engineering

         Criticare has focused its research, development and engineering
expenditures on products designed to meet identified market demands. The Company
seeks to apply its expertise in gas monitoring and related sensor technology to
develop new products and adapt existing products for new markets. At August 31,
1998, the Company had an in-house research, development and engineering staff of
25 people. The Company's research, development and engineering expenditures were
$3.3 million in fiscal 1998, $2.3 million in fiscal 1997 and $2.6 million in
fiscal 1996. Expenditures for fiscal 1998 include $900,000 which relates to the
commitment to issue shares of the Company's common stock for certain patented
technology.

Competition

         The markets for the Company's products are highly competitive. Many of
Criticare's competitors, including its principal competitors described below,
have greater financial resources, more established brand identities and
reputations, longer histories in the medical equipment industry and larger and
more experienced sales forces than Criticare. In these respects, such
competitors have a competitive advantage over the Company. The Company competes
primarily on the basis of product features, the quality and value of its
products (i.e., their relative price compared to performance features provided)
and the effectiveness of its sales and marketing efforts. The Company believes
that its principal competitive advantages are provided by its focus on cost
containment and its patented and other proprietary technology and software for
noninvasive, continuous monitoring of oxygen, specific anesthetic gases, carbon
dioxide and blood pressure, its cost-efficient manufacturing, the efficiency and
speed of its research and development efforts and its established international
presence.

         The principal competing manufacturers of pulse oximeters are Nellcor
Puritan Bennett, a unit of Mallinckrodt Inc., and Ohmeda, a division of The BOC
Group, Inc. The Company estimates that Nellcor has captured a majority, and that
Ohmeda and the Company have each captured significant portions of the worldwide
pulse oximeter market. In addition, there are approximately 30 other companies
which compete in the market for pulse oximeters. The Company also indirectly
competes with manufacturers of numerous other medical equipment products for
limited customer funds.

         The Company believes that the worldwide anesthetic agent and carbon
dioxide monitor markets are comparatively fragmented, with no dominant
competitor. The Company's principal competitors in the domestic gas monitor
market include Datex Medical Instrumentation, Inc., a United States subsidiary
of Instrumentarium OY, a Finnish company, Ohmeda and Datascope Corp. The


                                       9
<PAGE>   10

market for vital signs monitors includes competitors such as Hewlett-Packard
Company, Siemens A.G., Datex and SpaceLabs, Inc., a subsidiary of Westmark
International Incorporated.

         The Company believes that its principal competitors in Western Europe
include Datex and Ohmeda and that the Company has a significant share of this
market. In the Pacific Rim countries, the Company believes that Ohmeda is the
leading competitor and that Datex and the Company also have significant market
shares.

Regulation

         As a manufacturer of medical diagnostic equipment, the Company is
regulated by the FDA and similar foreign governmental agencies. In producing its
products, the Company must comply with a variety of regulations, including the
good manufacturing practices regulations of the FDA. In addition, it is subject
to periodic inspections by this agency. If the FDA believes that its legal
requirements have not been fulfilled, it has extensive enforcement powers,
including the ability to ban or recall products from the market and to prohibit
the operation of manufacturing facilities. The Company believes its products
comply with applicable FDA regulations in all material respects. In addition,
the Company received ISO 9002 certification on April 29, 1993 and ISO 9001
certification on July 8, 1994.

         Under the Federal Food, Drug and Cosmetic Act, as amended, all medical
devices are classified as Class I, Class II or Class III, depending upon the
level of regulatory control to which they will be subject. Class III devices,
which are the most highly controlled devices, are subject to premarket approval
by the FDA prior to commercial distribution in the United States.

         The Company's current products have not been subject to the FDA's
comprehensive premarket approval requirements, but are generally subject to
premarket notification requirements. If a new device is substantially equivalent
to a device that did not require premarket approval, premarket review is
satisfied through a procedure known as a "510(k) submission," under which the
applicant provides product information supporting its claim of substantial
equivalence. The FDA may also require that it be provided with clinical trial
results showing the device's safety and efficacy.

         The Company believes that the products it is currently developing
generally will be eligible for the 510(k) submission procedure and, therefore,
will not be subject to lengthy premarket approval procedures. However, these
products are still being developed and there can be no assurance that the FDA
will determine that the products may be marketed without premarket approval.



                                       10
<PAGE>   11


         Criticare seeks, where appropriate, to comply with the safety standards
of Underwriters' Laboratories and the Canadian Standards Association and the
standards of the European Community. To date, the Company has not experienced
significant regulatory expense or delay in the foreign markets in which it sells
its products. Industry and professional groups such as the American Society of
Anesthesiologists, to the extent they have the power to mandate certain
practices or procedures as part of their profession's standard of care, are also
a source of indirect regulation of the Company's business.

Patents and Trademarks

         The Company believes one of its principal competitive advantages is
provided by its patented and other proprietary technology including its sensor
technology, infrared specific anesthetic gas monitoring technology, UltraSync
signal processing software and disposable respiratory secretion filter system.
None of the Company's U.S. patents expire before 2004. Criticare also has three
foreign patent applications pending. There is no assurance that any patents held
or secured by the Company will provide any protection or commercial or
competitive benefit to the Company. There is also no assurance that the
Company's products will not infringe upon patents held by others. The Company is
the owner of United States trademark registrations for "POET" and "Scholar."

         The Company also relies upon trade secret protection for certain of its
proprietary technology. Although the Company requires its employees having
access to its proprietary information to sign confidentiality agreements, no
assurance can be given that such agreements can be effectively enforced or that
others will not independently develop substantially equivalent proprietary
information and techniques or otherwise gain access to or disclose the Company's
trade secrets.

Employees

         At August 31, 1998, Criticare had 117 employees; including 33 in
manufacturing and operations, five in quality control, 40 in sales and
marketing, 14 in administration and 25 in research, development and engineering.

         Many of the Company's technical employees are highly skilled. The
Company believes that its continued success depends in part on its ability to
continue to attract qualified management, marketing and technical personnel.
None of the Company's employees are subject to a collective bargaining
agreement. The Company believes that its relations with its employees are good.

Backlog

         Criticare's backlog on June 30, 1998 and 1997 was approximately
$1,542,000 and $1,184,000, respectively. The backlog at these dates consisted
primarily of products for which the sales order specified a delayed delivery
date. Criticare generally delivers its products out of inventory when specified
by the customer. The Company does not believe that its backlog at any date is
indicative of its future sales.

Item 2.    PROPERTIES.

         In November 1992, the Company purchased a new 60,000 square foot
facility for approximately $4.5 million. The Company's mortgage calls for
monthly installments of principal and interest of approximately $35,000 and a
final "balloon" payment of approximately $2.7 million in December 2002. The
Company believes this facility will be adequate for the foreseeable future.

Item 3.    LEGAL PROCEEDINGS.

         During fiscal 1998, the Company amicably settled separate pending legal
proceedings involving (i) Alan Brack, (ii) Messrs. Buckley and Joubert and Maria
Letica, and (iii) John Bombulie and Michael Cox. None of these settlements were
material to the Company's financial condition or results of operations.

         Prior to August, 1997, Criticare and a distributor of its products,
Dynamic Options Corporation ("D.O.C."), had a dispute over whether Criticare
could terminate the exclusive marketing agreement between the parties. On August
8, 1997, Criticare filed a Complaint against D.O.C. in the Waukesha County
Circuit Court. Criticare did not seek specific damages from D.O.C., but rather a
declaratory judgment that Criticare could terminate the exclusive marketing
agreement. On August 14, 1997, D.O.C. filed a Complaint in the Circuit Court for
Madison County, Alabama against Criticare and one of its employees, Fred Arbona.
The Complaint alleged that Criticare breached the terms of the exclusive
marketing agreement between the parties and that Criticare had committed fraud
and intentional interference with the business relationships between D.O.C. and
its customers. D.O.C. also alleged in its Complaint that Criticare violated the
Alabama Sales Representative Commission Contract Act by failing to pay
commissions due under the exclusive marketing agreement between the parties.
D.O.C. is seeking $5 million for each of the counts in its Complaint. On
September 12, 1997, Criticare filed a Notice of Removal of that case to the
Federal District Court in Alabama. However, the District Court remanded the case
to the Madison County Court. Criticare then filed a motion with the Madison
County Court to stay or dismiss the action in Alabama because of the prior
existing case in Waukesha County. The Madison County Court granted Criticare's
motion to


                                       12
<PAGE>   13

dismiss, but D.O.C. won a reversal on appeal. Criticare has appealed
the reversal to the Alabama Supreme Court and that appeal is pending. Likewise,
D.O.C. filed a motion with the Waukesha County Circuit Court to stay or dismiss
the action in Waukesha County due to the pending litigation in Alabama. D.O.C.
has also filed a counterclaim in the Waukesha County case alleging virtually the
same causes of action that it did in its Complaint against Criticare in Alabama.
Criticare believes that D.O.C.'s claims lack merit and remains committed to
litigate vigorously the disputed claims with D.O.C. At this time, it is not
possible to assess with any degree of accuracy Criticare's likelihood of
prevailing on its claims against D.O.C., nor the likelihood of prevailing with
regard to D.O.C.'s claims against Criticare.

         The Company does not currently believe that any of such claims which it
has received, either individually or in the aggregate, will have a material
adverse effect on the Company's results of operations or financial condition.

         From time to time the Company receives notices from competitors of
potential patent infringement. The Company does not currently believe that any
of such claims which it has received, either individually or in the aggregate,
will have a material adverse effect on the Company's results of operations or
financial condition. However, there can be no assurance that the Company will
not be sued for patent infringement or that if sued, the outcome of such suits
will not have an adverse effect on the Company.

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

                                    AGREEMENT

     This agreement, effective the date of last signature below, is between
CRITICARE SYSTEMS, INC. ("Criticare") and TELEMED TECHNOLOGIES INTERNATIONAL
INC. ("TTI").

                                    RECITALS

         A. TTI owns pending United States patent application No. 07/881,604
("the Patent Application") and certain know-how and technical information
relating to a homeview or similar monitoring system and complete, unencumbered
rights to manufacture, use and/or sell any invention disclosed and/or claimed
therein, including any equivalent inventions (the "Patent Rights"), and
Criticare desires an assignment of the Patent Rights, together with such
know-how and technical information from TTI.

         B. By this Agreement, TTI represents that the Patent Rights are pending
on appeal before the U.S. Patent Office. However, TTI acknowledges that the
compensation terms set forth herein account for the uncertain maturity and scope
of the Patent Rights, and Criticare desires to enter into this Agreement in
order to secure priority access to and/or ownership of the Patent Rights.

         C. It is the understanding of TTI and Criticare that by this Agreement,
Criticare has the unfettered right to the art of the Patent Application. Any
rights that TTI may have in other patents and copyrights will not preclude
Criticare from using the art described in the Patent Rights and not require
additional royalties to TTI beyond those stated in this Agreement.

         In consideration of the foregoing and the mutual covenants contained
herein, Criticare and TTI agree as follows:

1.       Compensation.

      (a)     Subject to prior receipt from TTI of the consent and waiver
described in paragraph 7, Criticare agrees to pay TTI a maximum of $50,000,
according to the following schedule: an initial $25,000 within ten (10) business
days of the effective date of this Agreement, and a maximum of $25,000
thereafter, as needed, for continued legal services for the appeal and/or the
prosecution of the Patent Application, provided the scope, nature, cost and
conduct of such legal services are acceptable to Criticare. TTI shall oversee
the continued appeal and/or prosecution of the Patent Application in Criticare's
name and in conformance with Criticare's instructions to positively pursue
patent allowance after the date of the assignment provided for in paragraph 2,
and shall provide Criticare with any and all know-how, technical information and
ongoing technical support as reasonably required to obtain the Patent
Application. To the extent any such know-how, technical information or support
include a TTI trade secret such trade secret shall be provided to Criticare only
upon the issue of a patent on the Patent Application, and with Criticare's
agreement to accept such a patent.

      (b)     Upon allowance of the Patent Application in a form containing no
amendments that, in the reasonable opinion of the parties' respective patent
counsel, undermine the original intent and scope of the Patent Application, TTI
will be entitled to additional compensation according to the following schedule:
(i.) during the four years after allowance of the Patent Application, 100,000
shares of Criticare common stock at no cost to TTI at the end of each such year,
and (ii) an additional 112 shares of Criticare common stock at no cost to TTI
for every subsequent homeview system sold by Criticare after the 1,500th system,
such subsequent sales limited to an additional 1,000 systems and such additional
shares limited to 112,000 shares. Criticare shall not be obliged to make any
extraordinary efforts to promote and sell homeview systems. Criticare will use
its best efforts to register such shares at such time TTI is eligible for such
shares. If, after the allowance of the Patent Application, it is the reasonable
opinion of the patent counsel of Criticare that the original intent and scope of
the Patent Application is not preserved or if TTI otherwise becomes ineligible
for the aforementioned stock, Criticare agrees to assign complete ownership of
the Patent Rights back to TTI. Such opinion regarding intent and scope shall be
presented in writing to TTI within thirty (30) business days of the date
Criticare receives notice of allowance and information regarding the final claim
language of the Patent Application. Upon such reassignment Criticare has the
right of first refusal to license the Patent Rights from TTI paying a royalty
not to exceed seven percent (7%) of net sales of homeview systems.

2.    Assignment and License Back. Upon initial payment by Criticare as provided
in paragraph 1(a), TTI will execute and return to Criticare the Assignment
attached hereto as Exhibit A, the entirety of which is incorporated herein,
thereby assigning the Patent Rights and specified know-how and/or technical
information to Criticare. Upon such assignment, Criticare shall enter into a
mutually-acceptable agreement granting a limited, royalty-free license

<PAGE>   2

to TTI for the term of the Patent issued from the Patent Application to use the
Patent Rights for ECG purposes only. Such license is attached as Exhibit B and
incorporated by reference.

3. Patent Prosecution and Appeal. TTI agrees to inform Criticare in a diligent
manner as to the course and substance of the appeal and/or prosecution of the
Patent Application. Accordingly, Criticare shall have the right to comment and
advise TTI. TTI acknowledges that the availability of shares of Criticare common
stock, as provided in paragraph 1(b), are contingent upon allowance of the
Patent Application in a form containing no amendments that, in the reasonable
opinion of the parties' respective patent counsel, undermine the original intent
and scope of the Patent Application. If such common stock is not issued to TTI,
Criticare will reassign the Patent Rights to TTI, as more fully provided in
paragraph 1(b), above.

4. Governing Law. This Agreement shall be interpreted, applied and performed
according to the laws of the State of Wisconsin without regard to conflict of
law principles.

5. Waiver. The failure of either party to insist, in any one or more instances,
upon performance of any of the terms, promises and conditions of this Agreement,
shall not be construed as a waiver or relinquishment of any right granted
hereunder or of the future performance of any such term, promise or condition.

6. Entire Agreement. This Agreement, together with Exhibits A and B which are
incorporated herein, constitutes and contains the entire agreement of the
parties with respect to the Patent Application and the Patent Rights. This
Agreement supersedes any and all prior understandings and agreements between the
parties. Any modification of this Agreement shall be in writing and executed in
the same manner as this Agreement.

7. Representations and Warranties. Both parties represent and warrant that they
have been duly authorized by their respective boards of directors to enter into
this agreement. TTI represents and warrants that its assets are greater than its
liabilities, such representation and warranty based on the value of the Patent
Rights being equal to the present value of the consideration set forth in
paragraph 1. TTI further represents and warrants that it owns all right, title
and interest in and to the Patent Rights free and clear of any and all liens or
encumbrances or, to its knowledge, the claims of others but for the security
interest in favor of National City Bank of Pennsylvania, whose consent to this
assignment and the waiver of its security interest TTI shall obtain within ten
days of the effective date of this Agreement. TTI further represents and
warrants that, to the best of its knowledge and based upon a reasonable
investigation, use of the Patent Rights do not infringe any rights of any third
party or any other rights of TTI.

8. Survival. This agreement and all of the provisions hereof shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors, and shall survive any mergers, acquisitions or other changes of
ownership of either party.

LETTER TO STOCKHOLDERS


Dear Fellow Stockholders:

During this past fiscal year, your Company continued its strategy to capitalize
on the opportunities that "managed care" represents. In contrast to the previous
"fee for service" system, managed care and its "cousin" capitation, limit
reimbursement levels on a per patient basis. In order to reduce the cost of care
under these conditions, health care providers strive to reduce the average
length of a hospital stay, decrease the number of elective procedures performed,
and more rigorously evaluate whether a patient qualifies for hospitalization.

The effect of all of this is that fewer patients are ultimately hospitalized,
but their acuity levels are higher, meaning that they are more seriously ill.
While a hospital's census may be lower than before, the arrival of managed care
has created a greater need for monitoring. Criticare's answer to this dilemma
was the introduction of MPT(TM) Multiple Parameter Telemetry, the world's first
patient-borne monitor that permits a physician to continually assess a patient's
cardiovascular and pulmonary status (i.e., ECG, blood pressure, pulse rate, and
oxygen saturation) anywhere in the hospital. This continuous surveillance of
vital signs permits more rapid assessment and timely treatment of adverse
conditions to improve clinical outcomes.

During our first year of marketing the MPT, we have focused on penetrating key
institutions that are reputed to be technology leaders in the health care
industry. The first article describing the benefits of MPT was published this
past summer. We expect more to follow in the coming months.

Our product development efforts have turned toward a new line of portable,
handheld products which we expect to be ready for shipment in the second fiscal
quarter of 1999. A natural spin-off of these products will include OEM modules
for several of our proprietary technologies as we anticipate expanding our share
of OEM markets.

Regarding Criticare's investment in Immtech, the Board of Directors approved a
spin-off of 750,000 Immtech common shares to Company shareholders in the form
of a stock dividend. The spin-off is expected to be consummated immediately
prior to the effectiveness of a public offering of Immtech common shares and
warrants. It is subject to a number of conditions, including a filing with the
Securities and Exchange Commission. However, no assurance can be given at this
time that the spin-off will be consummated.

While our past year's sales and earnings do not yet fully reflect the potential
impact that telemetry systems will ultimately contribute to revenues, we are
confident that the Company is well positioned to capitalize further on the
changing healthcare environment during this coming year. We are happy to report,
however, that efforts to streamline operations have been successful. Operating
expenses were significantly reduced due to various cost cutting measures
and our current ratio improved to a level of 4.2 as compared to 3.1 one year
ago.

On behalf of the management and the Board of Directors, we would like to thank
our devoted associates, our loyal customers, our quality-conscious vendors, and
our dedicated stockholders for their continued support.

Sincerely,



Gerhard J. Von der Ruhr                                 N.C. Joseph Lai, Ph.D.

</TABLE>

FISCAL YEAR ENDED JUNE 30, 1998 COMPARED TO JUNE 30, 1997

Net sales for the twelve months ended June 30, 1998 increased 6.3% to
$27,908,364 from $26,235,355 for the twelve months ended June 30, 1997. The
sales increase is attributable to the alternate care sales and new OEM sales.

The gross profit percentage remained relatively consistent at 46.7% versus 46.4%
in fiscal 1997. Margins in domestic hospital, alternate care, and international
all remained relatively consistent with those of the prior year.

Operating expenses of $12,731,695 decreased 6.3% from fiscal 1997 levels. In
addition, operating expenses as a percentage of sales decreased to 45.6% from
51.8% in fiscal 1997. The largest savings occurred in the marketing expenses
where spending levels were reduced by approximately $1,300,000. The reduction in
marketing expenses was primarily related to international spending. The Company
consolidated several international functions at the home office in the United
States. This resulted in a savings of over $850,000. Administrative expenses for
fiscal 1998 decreased by 20.4% from fiscal 1997 levels, due to liquidation
expenses incurred in fiscal 1997 related to Criticare International. The reduced
expenses in marketing and administration were partially offset by an increase of
41.3% in research, development, and engineering expenses, which resulted from a
$900,000 charge associated with the acquisition of in-process technology related
to the transmission of clinical data.

Interest expense decreased during fiscal 1998 due to no borrowings on the line
of credit during the year. Interest income increased during fiscal 1998 due to
higher cash balances on hand throughout the year. Equity in the loss of
investments relates to a $120,000 advance provided to Immtech International,
Inc.

FISCAL YEAR ENDED JUNE 30, 1997 COMPARED TO JUNE 30, 1996

Net sales for the twelve months ended June 30, 1997 decreased 17% to $26,235,355
from $31,528,266 for the twelve months ended June 30, 1996. Domestic hospital
sales decreased 40%, due to lower unit sales in all products and continued
competitive pricing conditions. In addition, marketing and sales efforts in this
division were concentrated on the market introduction of the
MPT(TM)/VitalView(TM) telemetry product. Alternate care sales decreased 12% and
international sales decreased 8%, due primarily to lower oximeter and gas
monitor sales due to a combination of competitive pricing and market demand
conditions in these two market areas.


                                        7

MD&A (CONT'D)

The gross profit percentage decreased to 46.4% in fiscal 1997 from 47.5% in
fiscal 1996. This decrease was due primarily to increased manufacturing expenses
related to new product introductions, the effect of lower sales volume on fixed
manufacturing expenses and continued price competition in the oximetry product
line affecting both the alternate care and international sales markets. Although
the Company has developed and released lower cost vital signs and telemetry
monitors and continues to develop lower cost oximeter and gas products, the
effect of pricing competition may continue to negatively affect gross profit
margins.

Operating expenses of $13,591,892 for fiscal 1997 decreased 16% from $16,155,513
for fiscal 1996. As a percentage of net sales, operating expenses increased to
51.8% in fiscal 1997 from 51.2% in fiscal 1996. Marketing expenses for fiscal
1997 decreased 25% to $8,761,731 from $11,686,368 for fiscal 1996 due primarily
to decreased sales commissions related to the lower sales volume and lower
advertising and sales promotion expenses. Research, development and engineering
expenses for fiscal 1997 decreased 10%, or $248,057 from fiscal 1996 expense
levels due to slightly lower staffing and project expenses. Administrative
expenses increased 32% or $609,073 when compared to fiscal 1996 due to an
increased provision for doubtful accounts receivable of $236,382 and costs
associated with a judgment against and the liquidation of Criticare
International GmbH Marketing Services ("Criticare International") of $417,553
offset in part by lower insurance costs.

Interest expense increased during fiscal 1997 due to increased short-term line
of credit borrowings and the interest and purchase discount associated with the
$2,500,000 convertible debentures issued during February 1997. Interest income
declined slightly due to lower cash balances invested during fiscal 1997. Equity
in loss of investments for fiscal 1997 included cash advances of $24,000 to
Immtech International, Inc. and a $300,000 charge related to the write-off of an
investment in a sleep apnea company compared to the fiscal 1996 charge of
$2,716,163 related to cash advances to and the purchase of 2,200,000 shares of
Immtech International, Inc. preferred stock.

Extraordinary gain on extinguishment of debt in the amount of $569,946 resulted
from the exchange of 200,000 shares of newly issued restricted Criticare common
stock in full payment of the $1,240,000 promissory note plus accrued interest of
approximately $110,000 associated with the fiscal 1996 purchase of Immtech
International, Inc. preferred stock.

QUARTERLY RESULTS

The following table contains unaudited quarterly information, which includes all
adjustments, consisting only of normal recurring adjustments, that the Company
considers necessary for a fair presentation. The Company recorded a charge of
$900,000 for the purchase of patented technology in the quarter ended June 30,
1998 and charges of $418,000 for a judgment against and the liquidation of
Criticare International and $300,000 for the write-off of the Intercare
Technologies, Inc. investment in the quarter ended June 30, 1997. These items
were unusual, nonrecurring adjustments.

The Company typically receives a substantial volume of its quarterly sales
orders at or near the end of each quarter. In anticipation of meeting this
expected demand, the Company usually builds a significant inventory of finished
products throughout each quarter. If the expected volume of sales orders is not
received during the quarter, or is received too late to allow the Company to
ship the products ordered during the quarter, the Company's quarterly results
and stock of finished inventory can be significantly affected.

LIQUIDITY AND CAPITAL RESOURCES

In fiscal 1998, the Company generated $448,434 from operating activities,
$194,431 from the exercise of stock options, $120,000 from the issuance of
common stock, and $82,000 from the exercise of warrants. The Company used
$147,441 for retirement of long-term debt, $288,285 for capital expenditures and
$120,000 for advances to Immtech International, Inc. These sources and uses of
cash resulted in a net positive cash flow of $289,139 for the 1998 fiscal year.

In fiscal 1997, the Company generated $1,491,171 from operating activities,
$2,500,000 from the issuance of convertible debentures, $400,919 from the
exercise of stock options and $180,000 from the exercise of warrants. The
Company used $2,300,000 for the retirement of borrowings under the bank line of
credit facility, $220,657 for costs associated with the issuance of the
convertible debentures, $217,619 for retirement of long-term debt, $175,600 for
capital expenditures and $24,000 for advances to Immtech International, Inc.
These sources and uses of cash resulted in a net positive cash flow of
$1,634,214 for the 1997 fiscal year.

The mortgage note requires monthly debt service payments of approximately
$35,000 with a final payment of approximately $2,702,000 due in December 2002.

The Company expects its continued programs to increase accounts receivable
collections, decrease inventory levels, reduce product development tooling
requirements, stabilize sales demonstration equipment levels and eliminate
advances to Immtech International, Inc. will have a positive affect on cash flow
activities in the next fiscal year. Consequently, the Company believes its
research and development activities and other capital and liquidity requirements
for the next one to two years will be satisfied by cash generated from
operations and other borrowings. During fiscal 1998, the Company also had access
to a commercial bank line of credit of up to $4,000,000. At June 30, 1998, there
were no borrowings outstanding on the line of credit. The Company violated a
convenant related to achieving certain income levels. The bank waived compliance
with this covenant subsequent to year end. This line expires in November 1998.
The Company currently expects that this line will be renewed.

The Company's Board of Directors has approved a spin-off of 750,000 Immtech
common shares to Company shareholders in the form of a stock dividend. The
spin-off is expected to be consummated immediately prior to the effectiveness of
a public offering of Immtech common shares and warrants. The spin-off is subject
to a number of conditions, including a filing with the Securities and Exchange
Commission, and no assurances can be given that the spin-off will be
consummated.

YEAR 2000 PREPARATIONS

The Company has developed a plan to address company-wide Year 2000 readiness.
The Year 2000 issue relates to computer hardware and software and other systems
designed to use two digits rather than four digits to define the applicable
year. As a result, the Year 2000 would be translated as two zeroes. Because the
Year 1900 could also be translated as two zeroes, systems which use two digits
could read the date incorrectly for a number of date-sensitive applications
resulting in potential calculation errors or the shutdown of major systems. The
Company is in the process of updating its internal computer software, other
information technology and other operating systems for the purposes of Year 2000
compliance. The Company will also address the Year 2000 compliance of the
Company's new and existing products. The Company currently expects to complete
its Year 2000 compliance plan during fiscal 1999 and does not expect that its
costs to become Year 2000 compliant will be material to its financial condition
or results of operations.

The Company's operations may also be adversely affected to the extent that
suppliers and other third parties are not Year 2000 compliant. The Company
intends to circulate surveys to its key third party vendors during fiscal 1999
to assess the Year 2000 compliance status of the operating systems of such
vendors and the potential impact on the Company of non-compliance. However, a
number of risks relating to the Year 2000 issue may be out of the Company's
control, including reliance on outside links for essential services such as
communications and power. There can be no assurance that a failure of systems of
third parties on which the Company's systems and operations will rely to be Year
2000 compliant will not have a material adverse effect on the Company's
business, financial condition or operating results.

FORWARD-LOOKING STATEMENTS

A number of the matters and subject areas discussed in this Annual Report that
are not historical or current facts deal with potential future circumstances and
developments. These include expected future financial results, liquidity needs,
financing ability, Year 2000 compliance, management's or the Company's
expectations and beliefs and similar matters discussed in Management's
Discussion and Analysis or elsewhere in this Annual Report. The discussions of
such matters and subject areas are qualified by the inherent risk and
uncertainties surrounding future expectations generally, and also may materially
differ from the Company's actual future experience.

The Company's business, operations and financial performance are subject to
certain risks and uncertainties which could result in material differences in
actual results from management's or the Company's current expectations. These
risks and uncertainties include, but are not limited to, general economic
conditions, demand for the Company's products and costs of operations.

NOTES TO FINANCIAL STATEMENTS


CRITICARE SYSTEMS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED JUNE 30, 1998, 1997  AND 1996


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements
     include the accounts of Criticare Systems, Inc. (the "Company") and its
     wholly owned subsidiaries: Criticare International GmbH Marketing Services
     ("Criticare International"), CSI Trading, Inc. ("CSI Trading"), Criticare
     Service GmbH, Criticare Biomedical, Inc. ("Criticare Biomedical"), Sleep
     Care, Inc. ("Sleep Care"), Criticare (FSC), Inc. and CSI International
     Corp. (DISC). Criticare International was liquidated during fiscal 1998.
     CSI Trading was incorporated in November 1996 to assist with European
     marketing activities. All significant intercompany accounts and
     transactions have been eliminated.

     CASH EQUIVALENTS -- The Company considers all investments with purchased
     maturities of less than three months to be cash equivalents.

     INVENTORIES -- Inventories are stated at the lower of cost or market, with
     cost determined on the first-in, first-out method.

     INVESTMENTS -- The Company accounts for its investment in Intercare
     Technologies, Inc. ("Intercare") on the cost method and accounts for its
     investment in Immtech International, Inc. ("Immtech") and Blatz House
     Offices Limited Partnership (the "Blatz Partnership") on the equity method
     (see Note 3).

     PROPERTY, PLANT AND EQUIPMENT -- Property, plant and equipment is recorded
     at cost. Each member of the Company's sales force is provided with
     demonstration monitors to assist them in their sales efforts. Also, the
     Company has loaner monitors which are used to temporarily replace a
     customer's unit when it is being repaired or upgraded. Depreciation is
     provided over the estimated useful lives of the assets. The building is
     being depreciated over 40 years, and the remaining assets are being
     depreciated over three to seven years, using primarily the straight-line
     method.

     LICENSE RIGHTS AND PATENTS -- License rights and patents are amortized over
     the estimated useful lives of the related agreements using primarily the
     straight-line method. Approximately $7,000, $9,000, and $42,000 of
     amortization was charged to operations in 1998, 1997 and 1996,
     respectively. Accumulated amortization approximated $78,000 and $71,000 at
     June 30, 1998 and 1997, respectively.

     CONVERTIBLE DEBENTURE ISSUANCE COSTS -- Convertible debenture issuance
     costs were amortized over the two-year term of the debentures.
     Approximately $15,000 and $46,000 of amortization was charged to operations
     in 1998 and 1997. The prorata amount of unamortized debenture issuance
     costs were charged to additional paid-in-capital upon conversion of the
     debentures to common stock. Unamortized debenture issuance costs charged to
     additional paid-in capital amounted to $100,822 and $61,872 during 1998 and
     1997. (See Note 6.)

     GOODWILL -- Goodwill relating to the excess of the cost over the fair value
     of the net assets of an acquired subsidiary was amortized on the
     straight-line method over approximately five years. Approximately $20,000
     and $29,000 of amortization was charged to operations in 1997 and 1996,
     respectively. The goodwill was fully amortized as of June 30, 1997.

     REVENUE RECOGNITION -- Revenues and the costs of products sold are
     recognized as the related products are shipped or installed, if there are
     significant installation costs.

     PRODUCT WARRANTIES -- Estimated costs for product warranties are accrued
     for and charged to operations as the related products are shipped.

     RESEARCH AND DEVELOPMENT EXPENSES -- Research and development costs are
     charged to operations as incurred. Such expenses approximated $3,156,000,
     $2,175,000 and $2,400,000 in 1998, 1997 and 1996, respectively. The 1998
     amount includes $900,000 related to certain acquired patented technology
     which was charged to operations as in-process research and development
     costs at the time of the acquisition. (See Note 8.)

     INCOME TAXES -- The Company accounts for income taxes using an asset and
     liability approach. Deferred income tax assets and liabilities are computed
     annually for differences between the financial statement and tax bases of
     assets and liabilities that will result in taxable or deductible amounts in
     the future based on enacted tax laws and rates applicable to the periods in
     which the differences are expected to affect taxable income.

     FOREIGN CURRENCY TRANSLATION -- The effects of unrealized exchange rate
     fluctuations from translating foreign currency assets and liabilities into
     United States dollars are accumulated as cumulative translation adjustments
     in stockholders' equity. Realized gains and losses from foreign currency

NOTES (CONT'D)

     NET INCOME (LOSS) PER COMMON SHARE -- On July 1, 1997, the Company adopted
     SFAS No. 128, "Earnings Per Share." Under SFAS No. 128, the Company changed
     the method used to compute earnings per share and restated all prior
     periods. The Company now reports basic and diluted earnings per share in
     place of primary and fully diluted earnings per share.

     FAIR VALUE OF FINANCIAL STATEMENTS -- The Company's financial instruments
     under Statement of Financial Account Standards ("SFAS") No. 107 "Disclosure
     About Fair Value of Financial Instruments," includes cash, accounts
     receivable, accounts payable, borrowings under line of credit facility,
     long-term debt and convertible debentures. The Company believes that the
     carrying amounts of these accounts are a reasonable estimate of their fair
     value because of the short-term nature of such instruments or, in the case
     of long-term debt and convertible debentures, because of interest rates
     available to the Company for similar obligations.

     APPROVED ACCOUNTING STANDARDS -- In 1997, the Financial Accounting Standard
     Board ("FASB") issued SFAS No. 130, "Reporting Comprehensive Income" and
     SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
     Information" which will be effective for the Company in fiscal 1999. The
     Company is currently evaluating the impact of adopting SFAS Nos. 130 and
     131. In 1998, the FASB issued SFAS No. 132, "Employers' Disclosures about
     Pensions and Other Postretirement Benefits." This statement is required to
     be adopted in fiscal 1999. SFAS No. 132 will have no impact on the
     Company's financial statements as the Company does not have a pension plan
     and it does not provide postretirement benefits. In 1998, the FASB also
     issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging
     Activities." This statement is required to be adopted in fiscal 2000. The
     Company is currently in the process of evaluating the impact of adopting
     SFAS No. 133.

     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 period. Actual results could differ from
     those estimates.

3.   INVESTMENTS

     INTERCARE TECHNOLOGIES, INC. -- During 1992, the Company's subsidiary,
     Sleep Care, transferred certain assets to Intercare Technologies, Inc.
     ("Intercare") in exchange for 75,000 shares of convertible preferred stock
     of Intercare with an estimated fair value of $300,000, at that time. In
     connection with the transfer, Sleep Care licensed to Intercare the rights
     to certain intellectual property and technology, primarily license rights
     and patents, related to products previously marketed by Sleep Care. In
     exchange for the license rights, the Company is to receive royalties of 5%
     of the gross revenues from sales of products licensed under the agreement.
     Royalty income approximated $33,000 in 1996. No income was recognized
     during 1998 and 1997. The assets retained by Sleep Care were fully
     amortized as of June 30, 1996. Amortization of the intellectual property
     approximated $8,000 in 1996. During the year ended June 30, 1997,
     management of the Company concluded the investment in Intercare was
     impaired and the carrying value of the investment was reduced from $300,000
     to zero.

     IMMTECH INTERNATIONAL, INC. -- During 1989, the Company acquired an initial
     investment interest in the common stock of Immtech International, Inc.
     ("Immtech") for $500,000. Immtech is a biopharmaceutical company focusing
     on the discovery and development of therapeutic products for the treatment
     of opportunistic diseases and cancer in patients with compromised immune
     responses. Immtech has two separate platform technologies for developing
     drugs, one based on developing a new class of molecules as pharmaceuticals
     and a second for developing a series of biological proteins that work in
     conjunction with the immune system.

     On December 21, 1995, the Company's subsidiary, Criticare Biomedical,
     purchased from Marquette Venture Partners II, L.P. and MVP Affiliates Fund,
     L.P. (collectively, the "Sellers") 1,000,000 shares of the $.01 par value
     Series A Preferred Stock ("Series A"), 1,200,000 shares of the $.01 par
     value Series B Preferred Stock ("Series B") of Immtech and a promissory
     note payable by Immtech to the Sellers in the principal amount of $50,000
     for approximately $2,136,000 payable in the form of 333,154 shares of the
     Company's common stock and a note payable for $1,240,000. Subsequent to
     June 30, 1998, the Series A and B preferred stock was exchanged for
     1,569,364 shares of Immtech's common stock. The Series A and Series B
     preferred stock were originally convertible by the holders to an equivalent
     number of shares of Immtech common stock and were redeemable at the option
     of the holders in December 1997.

                                       16

<PAGE>   16
     The Series A and Series B preferred stock had cumulative dividend
     preferences at a rate of 8% per annum. The Series A and Series B preferred
     stock contained voting rights equivalent to the number of shares of common
     stock issuable upon conversion.

     The acquisition price was assigned a value of approximately $2,136,000
     based upon an estimate by Company management of the fair value of the
     consideration given by the Company. The investment in Immtech is accounted
     for using the equity method. The purchase price was allocated to in-process
     research and development and charged to expense as an investment loss upon
     the consummation of the agreement. There was no significant tax benefit
     available on this charge.

     The following is a summary of the Company's investment in and advances to
     Immtech as of June 30, 1998 and 1997:

     The Series A and Series B preferred stock owned by the Company had a stated
     redemption value of approximately $3,398,000 and $3,150,000 as of June 30,
     1997 and 1996, respectively. The Company has recognized investment losses
     related to the investment in Immtech of $120,000, $24,000 and $2,716,163 in
     1998, 1997 and 1996, respectively. As of June 30, 1998, the Company owned
     approximately 5.3% and 65% of Immtech's issued and outstanding common and
     preferred stock respectively, or approximately 30% of the common stock on a
     fully diluted and as converted basis.

     Immtech was incorporated in 1984. Thus far, Immtech has directed its
     efforts toward research and development, hiring scientific and management
     personnel, arranging for facilities and conducting clinical trials. Immtech
     has no products currently available for sale, and none are expected to be
     commercially available for several years. Immtech has a March 31 fiscal
     year end.

     Since inception, Immtech has incurred accumulated losses of approximately
     $13,262,000 through March 31, 1998. Immtech is expected to continue to
     incur significant losses during the next several years. In addition, as of
     March 31, 1998, Immtech's current liabilities exceeded its current assets
     by approximately $3,639,000 and Immtech had a common stockholders'
     deficiency of approximately $9,022,000. In addition, Immtech was not in
     compliance with certain of its note agreements. These factors, among
     others, indicate that Immtech may be unable to continue as a going concern.

     Immtech's ability to continue as a going concern is dependent upon its
     ability to generate sufficient funds to meet its obligations as they become
     due and ultimately, to obtain profitable operations. Immtech's financial
     plans for the forthcoming year include the continuing efforts to obtain
     additional equity financing.

     The following is summarized financial information for Immtech at March 31,
     1998 and 1997 and for the years then ended.

     Subsequent to June 30, 1998, the Company purchased certain intangible
     assets and an additional 172,414 shares of Immtech common stock for
     $150,000. On July 24, 1998 (the "Effective Date"), Immtech completed a
     recapitalization (the "Recapitalization") pursuant to which: (i) Immtech
     effected a 0.645260-for-1 reverse stock split of all of the shares of
     common stock issued and outstanding immediately prior to the Effective
     Date, resulting in the reduction in the number of issued and outstanding
     shares of common stock from 2,305,166 to 1,487,431 (the "Reverse Stock
     Split"); (ii) Immtech's debtholders converted approximately $2,780,000 in
     stockholder advances (including the Company's advances), notes payable and
     related accrued interest outstanding immediately prior to the Effective
     Date into 1,209,962 shares of Immtech common stock (after giving effect to
     the Reverse Stock Split); (iii) Immtech's Series A Preferred stockholders
     converted 1,794,550 shares of Series A Preferred Stock issued and
     outstanding immediately prior to the Effective Date into 1,157,951 shares
     of common stock (after giving effect to the Reverse Stock Split); (iv)
     Immtech's Series B Preferres stockholders converted 1,600,000 shares of
     Series B Preferred Stock issued and outstanding immediately prior to the
     Effective Date into 1,232,138 shares of common stock (after giving effect
     to the Reverse Stock Split).

NOTES (CONT'D)


     Contemporaneously with the completion of the Recapitalization, Immtech
     issued and sold 1,150,000 shares of common stock for $0.87 per share, or
     aggregate consideration to Immtech of $1,000,000 to certain accredited
     investors. After the Recapitalization and issuance of 1,150,000 shares of
     common stock, the Company owned 2,187,684 shares of Immtech's issued and
     outstanding common stock, or approximately 28% on a fully-diluted basis.

     BLATZ PARTNERSHIP -- The Company is the sole limited partner in a real
     estate limited partnership which owns the Blatz Phase II Commercial Office
     Buildings located in Milwaukee, Wisconsin. Under terms of the Partnership
     Agreement (the "Agreement"), profits and losses (other than those resulting
     from a sale or refinancing of the Project) are to be allocated 40% to the
     general partners and 60% to the Company.

     The carrying value of the investment is zero. Recognition of any income by
     the Company for its interest in the Blatz Partnership will occur only after
     the Blatz Partnership has earnings in excess of previously unrecorded
     losses.

4.   INCOME TAXES

     The Company accounts for income taxes using an asset and liability approach
     which generally requires the recognition of deferred income tax assets and
     liabilities based on the expected future income tax consequences of events
     that have previously been recognized in the Company's financial statements
     or tax returns. In addition, a valuation allowance is recognized if it is
     more likely than not that some or all of the deferred income tax asset will
     not be realized. A valuation allowance is used to offset the related net
     deferred income tax assets due to uncertainties of realizing the benefits
     of certain net operating loss and tax credit carryforwards.

     Significant components of the Company's deferred income tax assets and
     deferred income tax liabilities are as follows:

</TABLE>

     At June 30, 1998, the Company had a $4,000,000 demand line of credit
     facility with a commercial bank to meet its short-term borrowing needs.
     Borrowings against the line were payable on demand with interest payable
     monthly at the bank's reference rate (8.75% as of June 30, 1998). As of
     June 30, 1998, there were no borrowings against the line. The line expires
     on November 15, 1998. Borrowings under the line of credit facility are
     collateralized by substantially all assets of the Company.

     In March 1997, the Company satisfied the $1,240,000 promissory note plus
     interest accrued on the note of approximately $110,000 in exchange for
     200,000 shares of newly issued common stock. Under the provisions of the
     agreement, the shares must be held for one full year prior to resale. In
     conjunction with this transaction, the Company recorded an extraordinary
     gain on the extinguishment of debt of $569,946 for the outstanding
     indebtedness under the promissory note in excess of the estimated fair
     market value of the restricted stock.

NOTES (CONT'D)


6.   CONVERTIBLE DEBENTURES

     In February 1997, the Company issued $2,500,000 of convertible debentures.
     The debentures had a two year term to maturity with a stated annual
     interest rate of 8%, payable in shares of common stock at the conversion
     date or maturity date. The holders of the debentures had the option to
     convert up to $1,250,000 of the debentures and accrued interest to common
     stock of the Company sixty-one (61) days after the February 1997 closing
     date at a conversion price equal to a 20% discount from the average closing
     bid price of the Company's common stock for the five days preceding the
     conversion date. Debentures aggregating $550,000 were converted under the
     20% discount conversion feature. The remaining debentures and accrued
     interest were converted to common stock of the Company at a conversion
     price equal to a 25% discount from the average closing bid price of the
     Company's common stock for the five days preceding the conversion date. For
     the years ended June 30, 1998 and 1997, $1,650,000 and $850,000 of
     debentures were converted to 407,761 and 216,173 shares of common stock
     with a fair market value of $2,298,357 and $1,117,594 as of the conversion
     dates.

     Proceeds from the issuance of the debentures were recorded as a liability
     at the issuance date. The conversion discount was amortized and reported as
     additional interest expense over the life of the debentures. Additional
     interest expense was recognized for any unamortized discount as of the
     conversion date. The debentures were included in the accompanying June 30,
     1997 consolidated balance sheet at the issuance price, plus any accrued
     interest and amortized discount.


7.   CONTINGENCIES

     The Company is involved in various lawsuits that have arisen from the
     normal conduct of business. These proceedings are handled by outside
     counsel. In the opinion of management, the ultimate resolution of these
     matters will not have a material effect on the consolidated financial
     statements.

     The Company has received two grants from the State of Wisconsin for
     research and development of certain products. The grants are to be repaid
     only upon successful completion and marketing of the related product.
     Repayment of these grants is to be made on a sales by unit basis, up to an
     aggregate of $600,000. Repayments approximated $14,000 and $30,000 in 1997
     and 1996, respectively, and in the aggregate, approximated $246,000 as of
     June 30, 1998. The repayments are charged to expense as the related
     products are sold. The Company has been awarded a third grant from the
     State of Wisconsin for an amount up to $100,000 which requires repayment of
     the grant amount plus interest at 8%, plus payment of a royalty in the
     amount of 1% of net sales of the related product for a five-year period, as
     defined. No funds have been received under this grant at June 30, 1998.


8.   STOCKHOLDERS' EQUITY

     STOCK OPTIONS -- In December 1992, the Board of Directors approved a new
     Employee Stock Option Plan and Non-Employee Stock Option Plan. No new stock
     options can be granted under the Employee Stock Option Plan and
     Non-Employee Stock Option Plan which existed prior to the approval of the
     new plans. The Board of Directors has authorized in connection with these
     new plans the issuance of 1,220,000 reserved shares of common stock of
     which 198,650 reserved shares of common stock remain available for future
     issuance under the stock option plans at June 30, 1998. The activity during
     1996, 1997 and 1998 for the above plans are summarized as follows:

options issued are contingent on future services or future events.

At June 30, 1998, 1,038,350 shares of common stock were reserved under the above
plans.

The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," but applies Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" and related
interpretations in accounting for its plans. If the Company had elected to
recognize compensation cost for the options granted during the years ended June
30, 1998, 1997, and 1996, consistent with the method prescribed by SFAS No. 123,
net loss and net loss per share would have been changed to the pro forma amounts
indicated below:

The fair value of stock options used to compute pro forma net loss and net loss
per common share is the estimated present value at the grant date using the
Black-Scholes option-pricing model. The pro forma effect on net loss for 1998,
1997, and 1996 is not representative of the pro forma effect in future years
because it does not take into consideration pro forma compensation cost related
to grants made prior to 1996.

STOCK WARRANTS -- In September 1995, the Company executed a warrant agreement
with a consultant. The warrant agreement provided for the issuance of warrants
to purchase up to 150,000 shares of the common stock of the Company, exercisable
at a price of $2.00 per share. The warrant was exercisable as to 37,500 shares
upon execution of the agreement and the warrants to purchase the remaining
112,500 shares were to become exercisable if certain performance parameters were
achieved by September 1996. Such parameters were not met as of such date. In
January 1997, the agreement was extended and the parameters were changed. During
the year ended June 30, 1997, the Company recognized $84,375 of expense related
to the value of the services performed by the consultant under the extended
agreement. By June 30, 1997, warrants to purchase the remaining 112,500 shares
of common stock at a price of $2.00 per share became exercisable. The warrant
holder exercised rights and purchased 41,000, 90,000, and 4,000 shares of common
stock at $2.00 per share during the years ended June 30, 1998, 1997, and 1996,
respectively. Warrants to purchase 15,000 shares of common stock at $2.00 per
share were exercisable as of June 30, 1998. Such warrants expire in September
2000.

In February 1998, the Company executed a similar warrant agreement with the
consultant. The warrant agreement provides for the issuance of warrants to
purchase up to 150,000 shares of common stock at a price of $3.00 per share. The
warrant is exercisable as to 30,000 shares upon execution of the agreement and
the warrants to purchase the remaining 120,000 shares will be exercisable if
certain performance parameters are achieved by February 1999. No such parameters
were achieved by June 30, 1998. During the year ended June 30, 1998, the Company
recognized $23,065 of expense related to the value of the services performed
under the agreement. As of June 30, 1998, 30,000 warrants were exercisable. Such
warrants expire in February 2003.

COMMITMENT TO ISSUE SHARES OF COMMON STOCK -- In April 1998, the Company agreed
to and accepted the patent rights assigned to them by a third party with respect
to certain technology related to the transmission of clinical data. In
consideration for the patent, the Company has agreed to provide the third party
with 400,000 shares of common stock payable over a four-year time period with
additional consideration of up to 112,000 shares contingent upon the achievement
of certain sales levels. The Company recorded a charge to operations of $900,000
in fiscal 1998 with respect to the value of the in-process technology which was
expensed as research and development costs. The 400,000 shares to be issued have
been considered to be outstanding shares for purposes of computing basic and
diluted income (loss) per common share.

NOTES (CONT'D)

     PREFERRED STOCK -- The Company's Board of Directors has the authority to
     determine the relative rights and preferences of any series it may
     establish with respect to the 500,000 shares of $.04 par value authorized
     preferred shares. No preferred stock is issued or outstanding.

     On March 27, 1997, the Board of Directors of the Company declared a
     dividend of one preferred share purchase right (a "Right") for each
     outstanding share of common stock of the Company. The dividend was made on
     April 24, 1997 to the stockholders of record on that date to purchase
     Preferred Stock ("Preferred") upon the occurrence of certain events. The
     Rights will be exercisable the tenth business day after a person or group
     acquires 20% of the Company's common stock, or makes an offer to acquire
     30% or more of the Company's common stock. When exercisable, each right
     entitles the holder to purchase for $25, subject to adjustment,
     one-hundredth of a share of Preferred for each share of common stock owned.
     Each share of Preferred will be entitled to a minimum preferential
     quarterly dividend of $25 per share, but not less than an aggregate
     dividend of 100 times the common stock dividend. Each share will have 100
     votes, voting together with the common stock. In the event of any merger,
     each share of Preferred will be entitled to receive 100 times the amount
     received per share of common stock. The Rights expire on April 1, 2007.

9.   EMPLOYEE BENEFIT PLAN
     The Company has a 401(k) plan which covers substantially all employees.
     Company contributions to the plan are discretionary and determined annually
     by the Company's Board of Directors. The Company's contributions were
     approximately $77,000, $81,000, and $61,000 in 1998, 1997 and 1996,
     respectively.

10.  BUSINESS AND CREDIT CONCENTRATIONS
     The Company's customers include domestic hospitals, domestic alternative
     health care sites and foreign health care markets. Although the Company's
     products are sold primarily to health care providers, concentrations of
     credit risk with respect to trade accounts receivable are limited due to
     the Company's large number of customers and their geographic dispersion.

     The Company currently coordinates substantially all international sales and
     distribution activities. Such activities were previously provided by the
     Company with the assistance of Criticare International. Identifiable assets
     located outside of the United States are insignificant in relation to the
     Company's total assets. Net export sales by geographic area are as follows:

INDEPENDENT AUDITORS' REPORT                                      

To the Stockholders and Directors of Criticare Systems, Inc.:

We have audited the accompanying consolidated balance sheets of Criticare
Systems, Inc. and subsidiaries as of June 30, 1998 and 1997, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended June 30, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Criticare Systems, Inc. and
subsidiaries at June 30, 1998 and 1997 and the results of operations and their
cash flows for each of the three years in the period ended June 30, 1998, in
conformity with generally accepted accounting principles.
