ITEM 1. BUSINESS

OVERVIEW

        The Company develops, manufactures and markets blood and tissue analysis
systems that provide immediate or continuous diagnostic results at the point of
patient care.  Since its commencement of operations in 1990, the Company has
transitioned from a development stage company to a full-scale development,
manufacturing and sales organization.  The Company's goal is to be the world
leader in critical care blood and tissue analysis systems.

        Blood and tissue analysis is an integral part of patient diagnosis and
treatment, and access to timely and accurate results is critical to effective
patient care.  The Company believes that its blood and tissue analysis systems
will result in more timely therapeutic interventions by providing accurate,
precise and immediate or continuous test results, thereby allowing faster
patient transfers out of expensive critical care settings and reducing patient
length of stay.  In addition, point of care testing can save money for hospitals
by reducing the numerous steps, paperwork and personnel involved in collecting,
transporting, documenting and processing blood and tissue samples.  Moreover,
point of care blood and tissue analysis could ultimately eliminate the need for
hospitals to maintain expensive and capital intensive stat laboratories.

        The Company's primary product focus  since its inception in 1990 has
been the development, manufacturing and marketing of the IRMA (Immediate
Response Mobile Analysis) System, an electrochemical-based blood analysis system
that provides rapid and accurate diagnostic results at the point of patient
care.   The IRMA SL System consists of a portable, microprocessor-based analyzer
that employs single-use, disposable cartridges to perform simultaneously several
of the most frequently  ordered blood tests in a simple 90-second procedure.

        The Company's first disposable electrochemical cartridge, introduced in
May 1994, performs three of the most frequently ordered blood tests for critical
care patients--the measurement of oxygen, carbon dioxide and acidity (the "blood
gases").  In June 1995, the Company expanded the IRMA System test menu with the
introduction of its electrolyte cartridge which measures sodium, potassium and
ionized calcium.  The Company  further expanded its critical or "stat" test menu
during the third quarter of 1996 with the release of the second-generation
system, IRMA SL, and the addition of the measurement of hematocrit to its
electrolyte cartridge.  With the addition of hematocrit, the IRMA SL System is
able to perform 95% of the critical or stat tests performed annually in the
United States, comprising  an estimated $1.2 billion annual market.  In 1997,
the Company introduced its third-generation system, IRMA SL Series 2000, and a
new combination testing cartridge.  The combination cartridge is based upon the
Company's new  "snapfit" cartridge design and gives clinicians the ability to
perform all critical blood gas, electrolyte and hematocrit tests using one small
blood sample and one  single-use cartridge.

        In the fourth quarter of 1996, the Company expanded its product line
with the introduction of a number of new products through the acquisition of
Biomedical Sensors, Ltd. (BSL), a Pfizer company.  With the acquisition of BSL
(now known as Diametrics Medical, Ltd.), the Company acquired a world-class
continuous monitoring fiberoptic technology platform, which complements the
Company's existing electrochemical sensor platform.  This product line includes
indwelling continuous blood monitoring systems, consisting of a monitor,
calibration system and intravascular disposable sensors.  Primary 

                                       2
<PAGE>
 
products include Paratrend 7+ and Neotrend, further described below in the
description of the Company's principal products.

PRINCIPAL PRODUCTS

        IRMA SL SERIES 2000 BLOOD ANALYSIS SYSTEM. The IRMA SL Series 2000
("IRMA SL System"), the third generation IRMA analysis system, was released in
the third quarter 1997, and provides the necessary foundation for all current
and future product enhancements. The IRMA SL System is comprised of the IRMA SL
analyzer and a variety of electrochemical-based disposable cartridges which
simultaneously perform select combinations of the most frequently ordered
critical care diagnostic tests of blood gases, electrolytes and hematocrit in a
simple 90-second procedure. The IRMA SL System also features electronic quality
control, as an alternative to aqueous quality control measures, which eliminates
the need for this costly and time-consuming process for many customers.

        The IRMA SL analyzer is a battery or AC operated, portable
microprocessor-based instrument weighing approximately four pounds, and includes
an on-board printer. The analyzer can be easily linked for data downloading
purposes to a hospital's laboratory or information system.

        In conjunction with a marketing alliance reached in 1997 with LifeScan,
a Johnson & Johnson company, the Company is incorporating blood glucose
monitoring into the IRMA platform by integrating LifeScan's SureStep(R) Pro
glucose module into the IRMA SL System. The Company expects to commercialize the
new integrated workstation during the first half of 1998.

        IDMS - THE IRMA DATA MANAGEMENT SYSTEM. Released in the third quarter of
1996, IDMS, an advanced data management software program, provides a
comprehensive data management system for point of care testing technologies.
Developed initially for the IRMA SL System, IDMS is network compatible and
features an open architecture design that allows the program to accept
applications and information from other devices.

        CAPILLARY COLLECTION DEVICE. The Capillary Collection Device was
introduced in the third quarter of 1996 as a new feature for use on the IRMA SL
System, which provides the capability to collect and test a capillary blood
sample. The Capillary Collection Device is used with the System's single use
cartridges to perform blood gas, electrolyte, and hematocrit testing. The
capillary collection capability of the IRMA SL System is useful in such patient
areas as neonatal and pediatric intensive care, and in other situations where a
capillary sample is preferred over an arterial or venous sample.

        AVOXIMETER 4000. Under a distribution agreement initiated in the third
quarter of 1996 with A-VOX Systems, Inc., the Company exclusively distributes
the AVOXimeter 4000 in the United States. The AVOXimeter 4000 is a battery-
operated and easily portable system which provides an accurate and timely
assessment of the levels of hemoglobin and calculated oxygen content in a
patient's blood.

        NEOCATH 1000. Introduced as part of the Company's acquisition of BSL,
Neocath 1000 is an umbilical artery oxygen monitoring system for neonatal
patients. The Neocath 1000 consists of a monitoring system and an umbilical
artery catheter, which allows direct, continuous and accurate measurement of
oxygen, with minimal physical disturbance to the neonate. The Company began
marketing the follow-on product to Neocath 1000, Neotrend, in the fourth quarter
of 1997.

        PARATREND 7+. Paratrend 7+ is the Company's second generation sensor
platform for its continuous monitoring products, and is the only multi-parameter
sensor for direct continuous monitoring of blood gases and temperature in
critically ill adult and pediatric patients. Inserted via an arterial catheter,
the sensor provides constant, precise measurement of vital blood gas parameters.
The new technology uses a fluorescent optical sensor for monitoring oxygen,
replacing the electrochemical version of its predecessor, Paratrend 7. The
Paratrend 7+ technology forms the basis for other new continuous monitoring
products, including Neotrend.

                                       3
<PAGE>
 
        NEOTREND. Based upon the new fluorescent optical sensor technology
introduced with the Paratrend 7+, Neotrend is the only multi-parameter system
for direct continuous monitoring of blood gases (oxygen, carbon dioxide and
acidity) and temperature in critically ill premature babies. Neotrend is the
Company's follow-on product to Neocath 1000. Neotrend was introduced in the
United Kingdom in November 1997 and the Company received FDA clearance to market
Neotrend in the United States in January 1998.

REGULATORY STATUS

        Human diagnostic products are subject, prior to clearance for marketing,
to rigorous pre-clinical and clinical testing mandated by the United States Food
and Drug Administration (the "FDA") and comparable agencies in other countries
and, to a lesser extent, by state regulatory authorities. The Company and its
products are regulated by the FDA under a number of statutes including the Food,
Drug and Cosmetic Act (the "FDC Act"). The FDC Act provides two basic review
procedures for medical devices. Certain products may qualify for a submission
authorized by Section 510(k) of the FDC Act, wherein the manufacturer gives the
FDA a pre-market notification of the manufacturer's intention to commence
marketing the product. The manufacturer must, among other things, establish that
the product to be marketed is substantially equivalent to another legally
marketed product. Marketing may commence when the FDA issues a letter finding
substantial equivalence. If a medical device does not qualify for the 510(k)
procedure, the manufacturer must file a pre-market approval ("PMA") application.
This procedure requires more extensive prefiling testing than the 510(k)
procedure and involves a significantly longer FDA review process.

        The Company has obtained clearances under Section 510(k) of the FDC Act
to market the IRMA SL System to test blood gases, electrolytes and hematocrit in
whole blood in hospital laboratories and at the point of care, and the Paratrend
7 to monitor blood gases and temperature. During 1997 additional Section 510(k)
pre-market notification clearances were obtained for the addition of glucose
testing capability to the IRMA SL System, and the expansion of the Paratrend 7
product line to include blood gas monitoring of critically ill neonates. The
Neotrend product is the first and only multi-parameter system for direct
continuous monitoring of blood gases and temperature in critically ill premature
babies.

        The Company submitted additional pre-market notifications for the IRMA-M
multi-use cartridge and the Neurotrend monitoring system in January 1998 that
are currently under review by the FDA. The addition of a multi-use cartridge,
IRMA-M, further enhances the IRMA SL System by allowing up to 50 separate test
panels to be performed on a single cartridge before disposal. The Neurotrend
monitoring system is designed for direct continuous monitoring for cerebral
ischemia and hypoxia in patients with severe head injury and also for use during
surgical intervention in the brain. Neurotrend continuously measures oxygen,
carbon dioxide, acidity and temperature.

        A 510(k) clearance is subject to continual review, and later discovery
of previously unknown problems may result in restrictions on the product's
marketing or withdrawal of the product from the market. The Company's long-term
business strategy includes development of cartridges and sensors for performing
additional blood and tissue chemistry tests, and any such additional tests will
be subject to the same regulatory process. No assurance can be given that the
Company will be able to develop such additional products or uses on a timely
basis, if at all, or that the necessary clearances for such products and uses
will be obtained by the Company on a timely basis or at all, or that the Company
will not be subjected to a more extensive prefiling testing and FDA approval
process. The Company also plans to market its products in several foreign
markets. Requirements vary widely from country to country, ranging from simple
product registrations to detailed submissions such as those required by the FDA.
Manufacturing facilities are also subject to FDA inspection on a periodic basis
and the Company and its contract manufacturers must demonstrate compliance with
current Good Manufacturing Practices ("GMP") promulgated by the FDA.

        The Company's product's are affected by the Clinical Laboratory
Improvement Act of 1988 ("CLIA") which has been implemented by the FDA. This law
is intended to assure the quality and 

                                       4
<PAGE>
 
reliability of all medical testing in the United States regardless of where
tests are performed. The regulations require laboratories performing blood
chemistry tests to meet specified standards in the areas of personnel
qualification, administration, participation in proficiency testing, patient
test management, quality control, quality assurance and inspections. The
regulations have established three levels of regulatory control based on test
complexity - "waived", "moderate complexity" and "high complexity". The tests
performed by the Company's IRMA SL System have been categorized under CLIA as
"moderate complexity" tests by the FDA, which places this system in the same
category as most other commercially available blood gas and blood chemistry
testing instruments.

RESEARCH AND DEVELOPMENT

        The Company owns two complementary technology platforms; an
electrochemical platform, on which IRMA intermittent testing products are based,
and a fiberoptic platform, on which the Paratrend 7 and Neotrend continuous
monitoring products are primarily based. The Company is pursuing product line
extensions from both of these core technology platforms.

        The Company intends to expand its cartridge and test menus available on
the IRMA SL System. In conjunction with a marketing alliance with LifeScan,
development has been completed to incorporate blood glucose monitoring on the
IRMA SL platform by integrating LifeScan's SureStep(R) Pro glucose module into
the IRMA SL System. Point of care glucose testing is the single largest point of
care test segment in hospitals. Additionally, currently under development is a
cartridge which tests sodium, potassium, ionized calcium, hematocrit, chloride
and blood urea nitrogen (BUN) using one single-use cartridge. In addition to the
single-use cartridge, the Company is developing a multi-use application that
will incorporate the Company's current sensor and calibration technologies into
products that can be used to perform up to 50 blood tests over a period of
several days before disposal. A multi-use system will serve the needs of high
volume critical care centers where rapid patient throughput and a low cost per
test panel is required. The Company believes that the IRMA SL System and related
core technologies provide a flexible platform which, with a limited amount of
additional development, will be capable of performing a variety of blood
chemistry tests.

        The Company plans to continually improve the IRMA SL System through
software upgrades, manufacturing process improvements and equipment redesign,
based on the results of ongoing marketing studies and field experience. 

        The Company has completed a new multi-parameter application of the
continuous monitoring technology for use with neonates, called Neotrend. This
application provides the only continuous blood gas and temperature monitoring of
neonatal patients and gives clinicians a more complete analysis of the
respiratory status and temperature of their patients. Clinical studies have been
initiated in the United Kingdom, and Section 510(k) clearance has been obtained
in the United States. Studies are also underway to apply the continuous
monitoring technology to other areas, including neurological applications.

        In February 1998, the Company filed a 510(k) application with the FDA
for its Neurotrend monitoring system, designed for direct continuous monitoring
for cerebral ischemia and hypoxia in patients with severe head injury and also
for use during surgical intervention in the brain.

        The Company has incurred research and development expenses of
approximately $7,232,000, $6,360,000 and $6,608,000 for the years ended December
31, 1997, 1996 and 1995, respectively.

SALES AND MARKETING

        The Company is focusing its marketing efforts for its blood analysis
systems on  acute care hospitals.  Near term sales of the Company's products are
expected to continue to come from hospital critical care departments where blood
tests are frequently requested on a stat basis.  The Company has also begun to
market the IRMA SL System for use in emergency transport vehicles.  The
Company's longer-term marketing objective is to penetrate smaller hospitals and
alternate-site markets, such as emergency medical facilities, home healthcare
agencies, outpatient clinics, skilled nursing homes and

                                       5
<PAGE>
 
doctors' offices or clinics. The Company believes that the potential advantages
of its blood analysis systems will form the basis of the Company's marketing
efforts to overcome the possible reluctance of acute care hospitals to change
standard operating procedures for performing blood testing or incur additional
capital expenses.

        The Company markets and distributes its products in the United States,
the United Kingdom and Germany through its direct sales and marketing
organization. Outside of these countries, the Company markets and distributes
its products through third party distribution channels, including corporate
partners strategically positioned to access targeted foreign markets, including
Japan and other Pacific Rim Countries, Europe, Mexico, Canada, Latin America and
South America. The Company may also consider additional distribution channels in
the United States, including joint ventures, licensing arrangements or OEM
relationships with strategically positioned corporate partners. Information
concerning the Company's export sales is contained in the financial section of
the Company's Annual Report to Shareholders for the year ended December 31,
1997, under Footnote 15, and is incorporated herein by reference.

        Additionally, the Company has entered into several arrangements with
hospital systems, healthcare facilities and other influential healthcare buying
groups which establish the Company as a preferred or sole source supplier of its
blood analysis systems. The Company expects to continue to enter into
arrangements with other buying groups and customers with respect to purchases of
its blood analysis systems.

MANUFACTURING

        The Company's manufacturing facilities support its intermittent testing
and continuous monitoring platforms and are located in Roseville, Minnesota and
High Wycombe, United Kingdom, respectively. The Company manufactures its IRMA
electrochemical thick-film sensor chips in its Roseville, Minnesota facility.
All other components of the IRMA cartridge are manufactured to the Company's
specifications by outside vendors. Components for the Company's continuous
monitoring sensors used in the Paratrend 7 and Neotrend products are sourced
from a variety of outside vendors, but the unique assembly of the sensing
elements is performed in the Company's High Wycombe facility. Sub-assembly of
external plastic assemblies are sub-contracted to outside vendors. The Company
uses external manufacturers to produce a range of hardware items, including the
IRMA SL analyzer and Paratrend 7 and Neotrend monitors. During 1998, portions of
the assembly of the IRMA SL analyzer and the continuous monitoring hardware will
be performed internally at the Roseville and High Wycombe facilities,
respectively. These devices could be manufactured by a number of
microelectronics assembly companies, using primarily off-the-shelf components.
Software for the IRMA SL analyzer is developed and maintained by the Company,
and software for the continuous monitoring products is jointly developed with an
external source, with acceptance and validation performed by the Company.

        The majority of the raw materials and purchased components used to
manufacture the Company's products are readily available. Most of the Company's
raw materials are or may be obtained from more than one source. A small number
of these materials, however, are unique in their nature , and are therefore
single sourced. Plans are ongoing to add additional second sourcing where
appropriate.

        The Company's manufacturing facilities include four clean rooms in
Roseville which range from Class 1,000 to Class 100,000, and two clean rooms in
High Wycombe, both rated as Class 10,000. The Company believes its current
facilities can support production of required cartridges and sensors for the
foreseeable future.

        The Company maintains a comprehensive quality assurance and quality
control program, which includes complete documentation of all material
specifications, operating procedures, maintenance and equipment calibration
procedures, training programs and quality control test methods. To control the
quality of its finished product, the Company utilizes ongoing statistical
process control systems during the manufacturing process and comprehensive
performance testing of finished goods.

        The Company continues to successfully undergo required inspections of
its manufacturing facilities by the FDA (most recently in February and March
1996 for Roseville and High Wycombe 

                                       6
<PAGE>
 
facilities, respectively), and by the British Standards Institution for the High
Wycombe facility (most recently in February 1996). As a result of these
inspections, the Company's manufacturing facilities and documentation and
quality control systems are deemed satisfactory and in compliance with Good
Manufacturing Practices (GMP).

PATENTS AND PROPRIETARY RIGHTS

        The Company has implemented a strategy of pursuing patent applications
to provide both design freedom and protection from competitors. This strategy
includes evaluating and seeking patent protection both for inventions most
likely to be used in its blood analysis systems and for those inventions most
likely to be used by others as competing alternatives.

        For its intermittent testing platform, the Company currently holds three
patents to its calibration technology, two patents related to its sensor
technology and one for companion technology. In addition, two patents have been
issued covering the IRMA SL analyzer and disposable cartridge designs. The
Company has received notice of allowance pertaining to patent applications
pending in the United States relating to electronic quality control and its
Capillary Collection Device. Additionally, the Company has submitted patent
applications and provisional patent applications pertaining to a multi-use
sensor module, an enzymatic sensor and coagulation measurement technology.
Overseas, the Company has foreign patent applications pending, filed under the
Patent Cooperation Treaty, designating various jurisdictions, including Canada,
the major European countries, Brazil, Australia and Japan, corresponding to one
or more U.S. applications. The Company has been issued nine foreign patents; two
in the United Kingdom, two in Germany, two in Canada and three in Japan.

        As it relates to its continuous monitoring platform, the Company has
been issued 21 U.S. patents associated with the design and manufacture of its
sensor technology platforms. These patents are at various patent process stages
in the major European countries and Japan.

        The Company is not currently a party to any patent litigation.
 
        The Company has federally registered the trademarks "IRMA SL",
"Diametrics Medical, Inc.", "Neocath", "Paratrend", "Tissuetrak", "Paratrend
7+", "Neotrend", "Neurotrend", "CAL-POD", "TOM 2000" and claims trademark rights
in "When Stat Isn't Fast Enough."

COMPETITION

        The Company believes that potential purchasers of point of care blood
analysis systems will base their purchase decision upon a combination of
factors, including the product's test menu, ease of use, accuracy, price and
ability to manage the data collected. The Company is aware of one company, i-
STAT, that has introduced and is marketing a portable point of care blood
analysis system. The Company believes that the IRMA SL System possesses distinct
competitive advantages over i-STAT's products including ease of use, closed
instead of open handling of blood samples and the ability to interface to the
hospital's laboratory or information system.

        The Company also competes with companies that market portable multi-use
blood gas systems. These companies include AVL Scientific Corporation, SenDx
Medical, Inc. and Instrumentation Laboratories with their acquisition of the GEM
Premier. However, the Company believes that to be successful in the point of
care market, a company's device must be able to perform a variety of commonly
ordered blood chemistry tests, as well as blood gas tests.

        The Company's blood analysis systems also compete with manufacturers
providing traditional blood analysis systems to central and stat laboratories of
hospitals. Although these laboratory-based instruments provide the same tests
available with the Company's products, they are complex, expensive and require
the use of skilled technicians. The Company believes that its blood analysis
systems offer several advantages over these laboratory-based instruments
including immediate or continuous results, ease-of-use, reduced opportunity for
error and cost effectiveness.

                                       7

        Many of the companies in the medical technology industry have
substantially greater capital resources, research and development staffs and
facilities than the Company. Such entities may be developing or could in the
future attempt to develop additional products competitive with the Company's
blood analysis systems. Many of these companies also have substantially greater
experience than the Company in research and development, obtaining regulatory
approvals, manufacturing and marketing, and may therefore represent significant
competition for the Company. There can be no assurance that the Company's
competitors will not succeed in developing or marketing technologies and
products that will be more effective or less expensive than those being marketed
by the Company or that would render the Company's technology and products
obsolete or noncompetitive.

                           DIAMETRICS MEDICAL, INC.
                             AMENDED AND RESTATED
                            1990 STOCK OPTION PLAN

1.   Purpose of Plan.
     --------------- 

          This Plan shall be known as the "DIAMETRICS MEDICAL, INC. 1990 STOCK
OPTION PLAN" and is hereinafter referred to as the "Plan." The purpose of the
Plan is to aid in maintaining and developing personnel capable of assuring the
future success of Diametrics Medical, Inc., a Minnesota corporation (the
"Company"), to offer such personnel additional incentives to put forth maximum
efforts for the success of the business, and to afford them an opportunity to
acquire a proprietary interest in the Company through stock options and other
long-term incentive awards as provided herein. Options granted under this Plan
may be either incentive stock options ("Incentive Stock Options") within the
meaning of Section 422 of the Internal Revenue Code of 1986 (the "Code"), or
options which do not qualify as Incentive Stock Options. Awards granted under
this Plan shall be SARs, restricted stock or performance awards as hereinafter
described.

2.   Stock Subject to Plan.
     --------------------- 

          Subject to the provisions of Section 15 hereof, the stock to be
subject to options or other awards under the Plan shall be the Company's
authorized but unissued shares of Common Stock, par value $.01 per share. Such
shares may be either authorized but unissued shares, or issued shares which have
been reacquired by the Company. Subject to adjustment as provided in Section 15
hereof, the maximum number of shares on which options may be exercised or other
awards issued under this Plan shall be 3,000,000 shares. If an option or award
under the Plan expires, or for any reason is terminated or unexercised with
respect to any shares, such shares shall again be available for options or
awards thereafter granted during the term of the Plan.

3.   Administration of Plan.
     ---------------------- 

          (a) The Plan shall be administered by a committee (the "Committee") of
two or more members of the Board of Directors of the Company, none of whom shall
be officers or employees of the Company and all of whom shall be "disinterested
persons" with respect to the Plan within the meaning of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any
successor rule or regulation thereto. The members of any such committee shall be
appointed by and serve at the pleasure of the Board of Directors.

          (b) The Committee shall have plenary authority in its discretion, but
subject to the express provisions of the Plan: (i) to determine the purchase
price of the Common Stock covered by each option or award, (ii) to determine the
<PAGE>
 
employees to whom and the time or times at which such options and awards shall
be granted and the number of shares to be subject to each, (iii) to determine
the form of payment to be made upon the exercise of an SAR or in connection with
performance awards, either cash, Common Stock of the Company or a combination
thereof, (iv) to determine the terms of exercise of each option and award, (v)
to accelerate the time at which all or any part of an option or award may be
exercised, (vi) to amend or modify the terms of any option or award with the
consent of the optionee, (vii) to interpret the Plan, (viii) to prescribe, amend
and rescind rules and regulations relating to the Plan, (ix) to determine the
terms and provisions of each option and award agreement under the Plan (which
agreements need not be identical), including the designation of those options
intended to be Incentive Stock Options, and (x) to make all other determinations
necessary or advisable for the administration of the Plan, subject to the
exclusive authority of the Board of Directors under Section 16 herein to amend
or terminate the Plan.

          (c) The Committee shall select one of its members as its Chairman and
shall hold its meetings at such times and places as it may determine. A majority
of its members shall constitute a quorum, provided that if the Committee is
comprised of no more than two members, all of its members must be present to
constitute a quorum. All determinations of the Committee shall be made by not
less than a majority of its members, provided that if the Committee is comprised
of no more than two members, such determinations may not be made by less than
all of its members. Any decision or determination reduced to writing and signed
by all of the members of the Committee shall be fully effective as if it had
been made by a majority vote at a meeting duly called and held. The grant of an
option or award shall be effective only if a written agreement shall have been
duly executed and delivered by and on behalf of the Company following such
grant. The Committee may appoint a Secretary and may make such rules and
regulations for the conduct of  business as it shall deem advisable.

          (d) The Chief Executive Officer of the Company shall have the
authority, as granted by the Committee pursuant to clause (ix) of subsection (b)
of this Section 3, to grant, pursuant to the Plan, options or other awards to
eligible persons who are not considered by the Company as its officers or
directors for purposes of Section 16 of the Securities Exchange Act of 1934, as
amended.  The Chief Executive Officer of the Company shall provide information
as to any grants made pursuant to this subsection to the Committee at their next
meeting.

4.   Eligibility.
     ----------- 

          Incentive Stock Options may only be granted under this Plan to any
full or part-time employee (which term as used herein includes, but is not
limited to, officers and directors who are also employees) of the Company and of
its present and future subsidiary corporations within the meaning of Section
424(f) of the Code 

                                      -2-
<PAGE>
 
(herein called "subsidiaries"). Full or part-time employees, consultants or
independent contractors to the Company or one of its subsidiaries shall be
eligible to receive options which do not qualify as Incentive Stock Options and
awards. In determining the persons to whom options and awards shall be granted
and the number of shares subject to each, the Committee may take into account
the nature of services rendered by the respective employees or consultant their
present and potential contributions to the success of the Company and such other
factors as the Committee in its discretion shall deem relevant. A person who has
been granted an option or award under this Plan may be granted additional
options or awards under the Plan if the Committee shall so determine; provided,
however, that for Incentive Stock Options granted after December 31, 1986, to
the extent the aggregate fair market value (determined at the time the Incentive
Stock Option is granted) of the Common Stock with respect to which all Incentive
Stock Options are exercisable for the first time by an employee during any
calendar year (under all plans described in subsection (d) of Section 422 of the
Code of his employer corporation and its parent and subsidiary corporations)
exceeds $100,000, such options shall be treated as options which do not qualify
as Incentive Stock Options. Nothing in the Plan or in any agreement thereunder
shall confer on any employee any right to continue in the employ of the Company
or any of its subsidiaries or affect, in any way, the right of the Company or
any of its subsidiaries to terminate his or her employment at any time.

5.   Price.
     ----- 

          The option price for all Incentive Stock Options granted under the
Plan shall be determined by the Committee but shall not be less than 100% of the
fair market value of the Common Stock at the date of grant of such option. The
option price for options granted under the Plan which do not qualify as
Incentive Stock Options and, if applicable, the price for all awards shall also
be determined by the Committee. For purposes of the preceding sentence and for
all other valuation purposes under the Plan, the fair market value of shares of
Common Stock shall be (i) the closing price of the Common Stock as reported for
composite transactions if the Common Stock is then traded on a national
securities exchange, (ii) the last sale price if the Common Stock is then quoted
on the NASDAQ National Market System, or (iii) the average of the closing
representative bid and asked prices of the Common Stock as reported on NASDAQ on
the date as of which the fair market value is being determined. If on the date
of grant of any option or award hereunder the Common Stock is not traded on an
established securities market, the Committee shall make a good faith attempt to
satisfy the requirements of this Section 5 and in connection therewith shall
take such action as it deems necessary or advisable.

                                      -3-
<PAGE>
 
6.   Term.
     ---- 

          Each option and award and all rights and obligations thereunder shall
expire on the date determined by the Committee and specified in the option or
award agreement. The Committee shall be under no duty to provide terms of like
duration for options or awards granted under the Plan, but the term of an
Incentive Stock Option may not extend more than ten (10) years from the date of
grant of such option and the term of options granted under the Plan which do not
qualify as Incentive Stock Options may not extend more than fifteen (15) years
from the date of granting of such option.

7.   Exercise of Option or Award.
     --------------------------- 

          (a) The Committee shall have full and complete authority to determine
whether an option or award will be exercisable in full at any time or from time
to time during the term thereof, or to provide for the exercise thereof in such
installments, upon the occurrence of such events (such as termination of
employment for any reason) and at such times during the term of the option as
the Committee may determine and specify in the option or award agreement.

          (b) The exercise of any option or award granted hereunder shall only
be effective at such time that the sale of Common Stock pursuant to such
exercise will not violate any state or federal securities or other laws. Only to
the extent required in order to comply with Rule 16b-3 under the Exchange Act,
in the case of an option or other award granted to a person considered by the
Company as one of its officers or directors for purposes of Section 16 of the
Exchange Act, the terms of the option or other award will require that such
shares are not disposed of by such officer or director for a period of at least
six months from the date of grant.

          (c) An optionee or grantee electing to exercise an option or award
shall give written notice to the Company of such election and of the number of
shares subject to such exercise. The full purchase price of such shares shall be
tendered with such notice of exercise. Payment shall he made to the Company in
cash (including bank check, certified check, personal check, or money order),
or, at the discretion of the Committee and as specified by the Committee, (i) by
delivering certificates for the Company's Common Stock already owned by the
optionee or grantee having a fair market value as of the date of grant equal to
the full purchase price of the shares, or (ii) by delivering the optionee's or
grantee's promissory note, which shall provide for interest at a rate not less
than the minimum rate required to avoid the imputation of income, original issue
discount or a below-market-rate loan pursuant to Sections 483, 1274 or 7872 of
the Code or any successor provisions thereto, or (iii) a combination of cash,
the optionee's or grantee promissory note and such shares. The fair market value
of such tendered shares shall be determined as provided in Section 5 herein. The
optionee's or grantee's promissory note shall be a 

                                      -4-
<PAGE>
 
full recourse liability of the optionee and may, at the discretion of the
Committee, be secured by a pledge of the shares being purchased. Until such
person has been issued the shares subject to such exercise, he or she shall
possess no rights as a shareholder with respect to such shares.

8.   Stock Appreciation Rights.
     ------------------------- 

          (a) Grant.  At the time of grant of an option or award under the Plan
              -----                                                            
(or at any other time), the Committee, in its discretion, may grant a Stock
Appreciation Right ("SAR") evidenced by an agreement in such form as the
Committee shall from time to time approve. Any such SAR may be subject to
restrictions on the exercise thereof as may be set forth in the agreement
representing such SAR, which agreement shall comply with and be subject to the
following terms and conditions and any additional terms and conditions
established by the Committee that are consistent with the terms of the Plan.

          (b) Exercise.  An SAR shall be exercised by the delivery to the
              --------                                                   
Company of a written notice which shall state that the holder thereof elects to
exercise his or her SAR as to the number of shares specified in the notice and
which shall further state what portion, if any, of the SAR exercise amount
(hereinafter defined) the holder thereof requests be paid to in cash and what
portion, if any, is to be paid in Common Stock of the Company. The Committee
promptly shall cause to be paid to such holder the SAR exercise amount either in
cash, in Common Stock of the Company, or any combination of cash and shares as
the Committee may determine. Such determination may be either in accordance with
the request made by the holder of the SAR or in the sole and absolute discretion
of the Committee. The SAR exercise amount is the excess of the fair market value
of one share of the Company's Common Stock on the date of exercise over the per
share exercise price in respect of which the SAR was granted, multiplied by the
number of shares as to which the SAR is exercised. For the purposes hereof, the
fair market value of the Company's shares of Common Stock shall be determined as
provided in Section 5 herein.

9.   Restricted Stock Awards.
     ----------------------- 

          Awards of Common Stock subject to forfeiture and transfer restrictions
may be granted by the Committee. Any restricted stock award shall be evidenced
by an agreement in such form as the Committee shall from time to time approve,
which agreement shall comply with and be subject to the following terms and
conditions and any additional terms and conditions established by the Committee
that are consistent with the terms of the Plan:

          (a) Grant of Restricted Stock Awards. Each restricted stock award made
              ---------------------------------                                 
under the Plan shall be for such number of shares of Common Stock as shall 

                                      -5-
<PAGE>
 
be determined by the Committee and set forth in the agreement containing the
terms of such restricted stock award. Such agreement shall set forth a period of
time during which the grantee must remain in the continuous employment of the
Company in order for the forfeiture and transfer restrictions to lapse. If the
Committee so determines, the restrictions may lapse during such restricted
period in installments with respect to specified portions of the shares covered
by the restricted stock award. The agreement may also, in the discretion of the
Committee, set forth performance or other conditions that will subject the
Common Stock to forfeiture and transfer restrictions. The Committee may, at its
discretion, waive all or any part of the restrictions applicable to any or all
outstanding restricted stock awards.

          (b) Delivery of Common Stock and Restrictions. At the time of a
              -----------------------------------------                  
restricted stock award, a certificate representing the number of shares of
Common Stock awarded thereunder shall be registered in the name of the grantee.
Such certificate shall be held by the Company or any custodian appointed by the
Company for the account of the grantee subject to the terms and conditions of
the Plan, and shall bear such a legend setting forth the restrictions imposed
thereon as the Committee, in its discretion, may determine. The grantee shall
have all rights of a shareholder with respect to the Common Stock, including the
right to receive dividends and the right to vote such shares, subject to the
following restrictions: (i) the grantee shall not be entitled to delivery of the
stock certificate until the expiration of the restricted period and the
fulfillment of any other restrictive conditions set forth in the restricted
stock agreement with respect to such Common Stock; (ii) none of the shares of
Common Stock may be sold, assigned, transferred, pledged, hypothecated or
otherwise encumbered or disposed of during such restricted period or until after
the fulfillment of any such other restrictive conditions; and (iii) except as
otherwise determined by the Committee, all of the Common Stock shall be
forfeited and all rights of the grantee to such Common Stock shall terminate,
without further obligation on the part of the Company, unless the grantee
remains in the continuous employment of the Company for the entire restricted
period in relation to which such shares of Common Stock were granted and unless
any other restrictive conditions relating to the restricted stock award are met.
Any Common Stock, any other securities of the Company and any other property
(except for cash dividends) distributed with respect to the Common Stock subject
to restricted stock awards shall be subject to the same restrictions, terms and
conditions as such restricted Common Stock.

          (c) Termination of Restrictions.  At the end of the restricted period
              ---------------------------                                      
and provided that any other restrictive conditions of the restricted stock award
are met, or at such earlier time as otherwise determined by the Committee, all
restrictions set forth in the agreement relating to the restricted stock award
or in the Plan shall lapse as to the restricted Common Stock subject thereto,
and a stock certificate for the appropriate number of shares of Common Stock,
free of the 

                                      -6-
<PAGE>
 
restrictions and the restricted stock legend, shall be delivered to the grantee
or his beneficiary or estate, as the case may be.

10.  Performance Awards.
     ------------------ 

          The Committee is further authorized to grant performance awards
("Performance Award"). Subject to the terms of this Plan and any applicable
award agreement, Performance Awards granted under the Plan (i) may be
denominated or payable in cash, Common Stock (including, without limitation,
restricted stock), other securities, other awards, or other property and (ii)
shall confer on the holder thereof rights valued as determined by the Committee,
in its discretion, and payable to, or exercisable by, the holder of the
Performance Awards, in whole or in part, upon the achievement of such
performance goals during such performance periods as the Committee, in its
discretion, shall establish. Subject to the terms of this Plan and any
applicable award agreement, the performance goals to be achieved during any
performance period, the length of any performance period, the amount of any
Performance Awards granted, and the amount of any payment or transfer to be made
by the grantee and by the Company under any Performance Awards shall be
determined by the Committee.

11.  Income Tax Withholding and Tax Bonuses.
     -------------------------------------- 

          (a) In order to comply with all applicable federal or state income tax
laws or regulations, the Company may take such action as it deems appropriate to
ensure that all applicable federal or state payroll, withholding, income or
other taxes, which are the sole and absolute responsibility of an optionee or
grantee under the Plan, are withheld or collected from such optionee or grantee.
In order to assist an optionee or grantee in paying all federal and state taxes
to be withheld or collected upon exercise of an option or award which does not
qualify as an Incentive Stock Option hereunder, the Committee, in its absolute
discretion and subject to such additional terms and conditions as it may adopt,
shall permit the optionee or grantee to satisfy such tax obligation by (i)
electing to have the Company withhold a portion of the shares otherwise to be
delivered upon exercise of such option or award with a fair market value,
determined in accordance with Section 5 herein, equal to such taxes or (ii)
delivering to the Company Common Stock other than the shares issuable upon
exercise of such option or award with a fair market value, determined in
accordance with Section 5, equal to such taxes.

          (b) The Committee shall have the authority, at the time of grant of an
option under the Plan or at any time thereafter, to approve tax bonuses to
designated optionees or grantees to be paid upon their exercise of options or
awards granted hereunder. The amount of any such payments shall be determined by
the Committee. The Committee shall have full authority in its absolute
discretion to 

                                      -7-
<PAGE>
 
determine the amount of any such tax bonus and the terms and conditions
affecting the vesting and payment thereafter.

12.  Additional Restrictions.
     ----------------------- 

          The Committee shall have full and complete authority to determine
whether all or any part of the Common Stock of the Company acquired upon
exercise of any of the options or awards granted under the Plan shall be subject
to restrictions on the transferability thereof or any other restrictions
affecting in any manner the optionee's or grantee's rights with respect thereto,
but any such restriction shall be contained in the agreement relating to such
options or awards.

13.  Ten Percent Shareholder Rule.
     ---------------------------- 

          Notwithstanding any other provision in the Plan, if at the time an
option is otherwise to be granted pursuant to the Plan the optionee owns
directly or indirectly (within the meaning of Section 424(d) of the Code) Common
Stock of the Company possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or its parent or
subsidiary corporations, if any (within the meaning of Section 422(b)(6) of the
Code), then any Incentive Stock Option to be granted to such optionee pursuant
to the Plan shall satisfy the requirements of Section 422(c)(5) of the Code, and
the option price shall be not less than 110% of the fair market value of the
Common Stock of the Company determined as described herein, and such option by
its terms shall not be exercisable after the expiration of five (5) years from
the date such option is granted.

14.  Non-Transferability.
     ------------------- 

          No option may be sold, pledged, assigned, hypothecated, transferred,
or disposed of in any manner other than (i) by will or by the laws of descent or
distribution, or (ii) in the case of options that are not Incentive Stock
Options, to members of the optionee's immediate family or to one or more trusts
for the benefit of the optionee or members of his or her immediate family, and
the option may be exercised, during the lifetime of the Optionee, only by the
optionee or a permitted transferee.

15.  Dilution or Other Adjustments.
     ----------------------------- 

          If there shall be any change in the Common Stock through merger,
consolidation, reorganization, recapitalization, dividend in the form of stock
(of whatever amount), stock split or other change in the corporate structure,
appropriate adjustments in the Plan and outstanding options and awards shall be
made by the Committee. In the event of any such changes, adjustments shall
include, where appropriate, changes in the aggregate number of shares subject to
the 

                                      -8-
<PAGE>
 
Plan, the number of shares and the price per share subject to outstanding
options and awards and the amount payable upon exercise of outstanding awards,

execution and delivery of an option or award agreement), shall constitute the
granting of an option or award hereunder.

amended, or the rules thereunder. All grants of Options hereunder shall be made

     covered by such Options.

               (ii)   Effective August 14, 1997, each Outside Director shall be
     automatically granted an Option (an "Initial Grant") to purchase 18,000
     Shares on the date on which such person first becomes a Director, whether
     through election by the shareholders of the Company or appointment by the
     Board of Directors to fill a vacancy.  Options granted under this section
     4(b)(ii) shall become vested and thereby exercisable with respect to 50% of
     such Initial Grant on the twelve month anniversary date of such Initial
     Grant and with respect to 25% at each successive anniversary date;
     provided, however, an unvested portion of an Initial Grant shall only vest
     so long as the Outside Director remains a Director on the date such portion
     vests.

               (iii)  Effective August 14, 1997, each Outside Director shall
     automatically receive, on the date of each Annual Meeting of Shareholders,
     an Option to purchase 8,000 Shares of the Company's Common Stock, such
     Option to become exercisable six months subsequent to the date of grant;
     provided however, that such Option shall only be granted to Outside
     --------                                                           
     Directors who have served since the date of the last Annual Meeting of
     Shareholders and will continue to serve after the date of grant of such
     Option.

               (iv)   Each Outside Director may elect, not later than the last
     day of the Company's fiscal year, to be granted Options in lieu of the
     compensation and fees otherwise payable to such Outside Director for the
     next fiscal year. Such Options shall be granted quarterly on the last day
     of each fiscal quarter in which such compensation and fees are earned, to
     be exercisable immediately. The number of Shares covered by each such
     Option shall be the number determined by dividing the total amount of
     compensation and fees payable at the end of such quarter by the Option
     Value of one such Share on the date of grant.

               (v)    The terms of an Option granted hereunder shall be as
     follows:

                    (A) the term of the Option shall be ten (10) years.

               Director remains a Director of the Company, except as set forth
               in Section 8 hereof.

                    (C) the exercise price per Share shall be 100% of the fair
               value per Share on the date of grant of the Option.

                    (D) to the extent necessary to comply with the applicable
               provisions of Rule 16b-3 promulgated under the Exchange Act
               ("Rule 16b-3"), no Option will be exercisable until a date more

               Option.

other holders of any Options granted under the Plan.

          -----------                                                         
Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) hereof.

     The Plan shall not confer upon any Optionee any right with respect to

may have to terminate his directorship at any time.

provisions of Section 16(b) of the Exchange Act, (or other applicable law), the

     8.   Exercise of Option.
          -------------------

          (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option
               -----------------------------------------------             
granted hereunder shall be exercisable at such times as are set forth in Section
4(b) 

                                      -5-

        --------                                                    
approval of the Plan in accordance with Section 16 hereof has been obtained.

     An Option may not be exercised for a fraction of a Share.

     An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may consist of any consideration and method of payment
allowable under Section 7(c) of the Plan.  Until the issuance (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares,
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option.  A share certificate for the number of Shares so acquired shall be
issued to the Optionee as soon as practicable after exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 10 of the Plan.

     Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)  Termination of Status as a Director.  If an Outside Director
               -----------------------------------                         
ceases to serve as a Director, he may, but only within seven (7) months after
the date he ceases to be a Director of the Company, exercise his Option to the
extent that he was entitled to exercise it at the date of such termination.  To
the extent that he was not entitled to exercise an Option at the date of such
termination, or if he does not exercise such Option (which he was entitled to
exercise) within the time specified herein, the Option shall terminate.

          (c)  Disability of Optionee.  Notwithstanding the provisions of 
               ----------------------   
Section 8(b) above, in the event an Optionee is unable to continue his service
as a Director with the Company as a result of his total and permanent disability
(as defined in Section 22(e)(3) of the Code) he may, but only within seven (7)
months from the date of termination, exercise his Option to the extent he was
entitled to exercise it at the date of such termination. To the extent that he
was not entitled to exercise the Option at the date of termination, or if he
does not exercise such Option (which he was entitled to exercise) within the
time specified herein, the Option shall terminate.

          (d)  Death of Optionee.  Notwithstanding the provisions of Section
               -----------------                                            
4(b), in the event of the death of an Optionee:

                                      -6-
<PAGE>
 
               (i)   during the term of the Option who is at the time of his
     death a Director of the Company and who has been in Continuous Status as a
     Director since the date of grant of the Option, the Option may be
     exercised, at any time within seven (7) months following the date of death,
     by the Optionee's estate or by a person who acquired the right to exercise
     the Option by bequest or inheritance, but only to the extent of the right
     to exercise that would have accrued had the Optionee continued living and
     remained in Continuous Status as a Director for six (6) months after the
     date of death; or

               (ii)   within thirty (30) days after the termination of
     Continuous Status as a Director, the Option may be exercised, at any time
     within seven (7) months following the date of death, by the Optionee's
     estate or by a person who acquired the right to exercise the Option by
     bequest or inheritance, but only to the extent of the right to exercise
     that had accrued at the date of termination.

     9.   Non-Transferability of Options.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than (i)
by will, (ii) by the laws of descent or distribution, (iii) to members of the
Optionee's immediate family or (iv) to one or more trusts for the benefit of the
Optionee or members of his or her immediate family, and the Option may be
exercised, during the lifetime of the Optionee, only by the Optionee or a
permitted transferee.

     10.  Adjustments Upon Changes in Capitalization, Dissolution or Merger.
          ----------------------------------------------------------------- 

          (a)  In the event that the number of outstanding shares of Common
Stock of the Company is changed by a stock dividend, stock split, reverse stock
split, combination, reclassification or similar change in the capital structure
of the Company without consideration, the number of Shares available under this
Plan and the number of Shares subject to outstanding Options and the exercise
price per share of such Options shall be proportionately adjusted, subject to
any required action by the Board or shareholders of the Company and compliance
with applicable securities laws; provided however, that no certificate or scrip
                                 --------                                      
representing fractional shares shall be issued upon exercise of any Option and
any resulting fractions of a Share shall be ignored.  Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive.

          (b)  In the event of a dissolution or liquidation of the Company, a
merger in which the Company is not the surviving corporation, a transaction or
series of related transactions in which 100% of the then outstanding voting
stock is sold or otherwise transferred, or the sale of substantially all of the
assets of the Company, any or all outstanding Options shall, notwithstanding any
contrary terms of the written agreement governing such Option, accelerate

<PAGE>
 
and become exercisable in full at least ten days prior to (and shall expire on)
the consummation of such dissolution, liquidation, merger or sale of stock or
sale of assets on such conditions as the Board shall determine unless the
successor corporation assumes the outstanding Options or substitutes
substantially equivalent options.

     11.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date determined in accordance with Section 4(b) hereof.
Notice of the determination shall be given to each Outside Director to whom an
Option is so granted within a reasonable time after the date of such grant.

     12.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a)  Amendment and Termination.  The Board may at any time amend,
               -------------------------                                   
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuance shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent.  In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act (or any other applicable law or regulation), the Company shall
obtain shareholder approval of any Plan amendment in such a manner and to such a
degree as required.

          (b)  Effect of Amendment or Termination.  Any such amendment or
               ----------------------------------                        
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

     13.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

     As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares, if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

                                      -8-
<PAGE>
 
     Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

     14.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------

requirements of the Plan.

     15.  Option Agreement.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Board shall approve.

     16.  Shareholder Approval.
          -------------------- 

          (a)  The Plan shall be subject to approval by the shareholders of the
Company within twelve (12) months of its adoption by the Board.  If such
shareholder approval is obtained at a duly held shareholders' meeting, it may be
obtained by the affirmative vote of the holders of a majority of the outstanding
shares of the Company present or represented and entitled to vote thereon.  If
such shareholder approval is obtained by written consent, it may be obtained by
the written consent of the holders of a majority of the outstanding shares of
the Company.

          (b)  Any required approval of the shareholders of the Company shall be
substantially in accordance with Section 14(a) of the Exchange Act and the rules
and regulations promulgated thereunder.

     17.  Information to Optionees.  The Company shall provide to each Optionee,
          ------------------------

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

     SUMMARY

     Diametrics Medical, Inc., which began operations in 1990, is engaged in the
     development, manufacturing and marketing of critical care blood and tissue
     analysis systems which provide immediate or continuous diagnostic results
     at the point of patient care.

     Since its commencement of operations in 1990, the Company has transitioned
     from a development stage company to a full-scale development, manufacturing
     and sales organization. As of December 31, 1997, the primary funding for
     the operations of the Company has been approximately $114 million raised
     through public and private sales of its equity securities and issuance of
     convertible promissory notes, all of which have been repaid or converted
     into common stock.

     During 1997, several significant events occurred which impacted 1997
     operating results and will continue to impact operating results in the
     future. These events were highlighted by the introduction and enhancement
     of key new products, continued market penetration of the Company's products
     and the successful integration and expanded commercialization of the
     continuous monitoring business, purchased from Pfizer Inc. in November
     1996.

     Key among the Company's new product introductions in 1997 was the launch of
     a new combination testing cartridge for the IRMA SL Blood Analysis System.
     The
<PAGE>
 
     combination cartridge is based upon the Company's new "snapfit" cartridge
     design and gives clinicians the ability to perform all critical blood gas,
     electrolyte and hematocrit tests using one small blood sample on one 
     single-use cartridge. The addition of this cartridge extends the system's
     application to all critical care areas in the hospital including the
     operating room. The new "snapfit" cartridge design is smaller than its
     predecessor and facilitates automated assembly, which reduces labor cost,
     while increasing yields and plant capacity, all contributing to lower unit
     product costs and improved margins.

     Another major product and marketing breakthrough in 1997 was the completion
     of an agreement with LifeScan, a Johnson & Johnson company, to incorporate
     blood glucose monitoring into the IRMA SL System by integrating LifeScan's
     SureStep(R) Pro glucose module into the system.  The Company expects to
     commercialize the new integrated workstation during the first half of 1998.
     Diametrics and LifeScan are also collaborating on worldwide sales and
     marketing efforts.

     Fundamental to the expanded commercialization of the continuous monitoring
     business was the Company's receipt of FDA clearance to market its second
     generation sensor platform for continuous monitoring products. The
     Paratrend 7+ is the only multi-parameter sensor for direct continuous
     monitoring of blood gases in critically ill adult and pediatric patients.
     The new technology utilizes a fluorescent optical sensor for monitoring
     oxygen, replacing the electrochemical version of its predecessor. The new
     technology platform has lower material costs and requires less
     manufacturing labor, resulting in lower unit costs. The Paratrend 7+
     technology forms the basis for other new continuous monitoring products,
     including Neotrend. Neotrend is designed specifically to provide continuous
     monitoring of blood gases and temperature in critically ill premature
     babies. Neotrend was introduced in the United Kingdom in November 1997 and
     the Company received FDA clearance to market Neotrend in the United States
     in January 1998.

     Additionally, the Company continued to expand global marketing and
     distribution partnerships during the year, including the initiation of a
     co-marketing  agreement with Marquette Medical Systems, Inc., and the
     expansion of its distribution agreement with Chiron Diagnostics to include
     selected markets in the Far East and southern Europe. Chiron is also a
     distribution partner for the Company's Paratrend 7 system in Japan. The
     co-marketing agreement with Marquette enables Marquette's U.S. sales force
     to quote and sell the IRMA SL Blood Analysis System as part of Marquette's
     monitoring solutions portfolio.  The co-marketing effort is an outgrowth of
     a strategic alliance between the two companies, initiated to develop an
     interface that links the benefits of the IRMA SL Blood Analysis System to
     Marquette's Unity Monitoring Network(R).  The interface will transfer IRMA
     test information immediately into Marquette's bedside monitor or clinical
     information system thus creating a comprehensive, real-time patient record.

     As previously noted, in November 1996, the Company acquired all the
     outstanding capital stock of Biomedical Sensors, Ltd. (BSL), an operating
     unit of Pfizer Inc., and certain assets from Howmedica, Inc., a wholly
     owned subsidiary of Pfizer Inc.  The combined operations of these former
     Pfizer entities are collectively referred to below as "Biomedical Sensors".
     Based in England, the new subsidiary, Diametrics Medical, Ltd. (DML),
     brings a product line which includes indwelling continuous blood monitoring
     systems utilizing a fiber optic technology platform.  Primary products
     include Paratrend 7, Paratrend 7+ and Neotrend, described above.  Each of
     these products consists of a monitoring system and intravascular disposable
     sensors.

     RESULTS OF OPERATIONS

     SALES  Sales of the Company's products were $10,434,366 for 1997, compared
     to $3,796,816 for 1996 and $1,607,375 in 1995.  1997 revenues reflect the
     first full year of sales from the operations of the Company's subsidiary,
     DML. Compared to pro forma combined Diametrics' and Biomedical Sensors'
     sales for the year ended December 31, 1996, sales increased approximately
     50% in 1997.  The Company's revenues are affected principally by the number
     of instruments, both monitors and IRMA analyzers, placed with customers and
     the rate at which disposable sensors and cartridges are used in connection
     with these products. From inception through December 31, 1997, the Company
     has sold over 2,200 instruments. Compared to pro forma combined Diametrics'
     and Biomedical Sensors' unit sales for 1996, unit sales of instruments in
     1997 increased approximately 40%, while disposable sensor and cartridge
     unit sales increased approximately 80%.

     The Company has targeted 1998 revenue growth in excess of 50% relative to
     1997 as a result of further planned expansion of the blood and tissue
     analysis product lines and continued market penetration of existing
     products.

     COST OF SALES Cost of sales totaled $11,666,142 for 1997, compared to
     $9,860,259 for 1996 and $8,703,859 for 1995. Included in cost of sales for
     1995 was a charge of approximately $1.3 million associated with the write-
     down of inventory to the lower of cost or market as a result of product
     obsolescence and unfavorable manufacturing variances. Cost of sales as a
     percentage of revenue was 112% in 1997, 260% in 1996 and 460% in 1995
     (without the impact of the 1995 charge). On a pro forma combined basis of
     Diametrics' and Biomedical Sensors' operations for 1995 and 1996, cost of
     sales as a percentage of revenue was 281% and 208%, respectively. The
     significant year-to-year improvement in the Company's cost of sales as a
     percentage of revenue reflects increased sensor and cartridge volumes,
     improved manufacturing yields, increased shelf life of cartridges and the
     impact of cost controls and manufacturing process changes. These
     improvements resulted in the Company's first positive quarterly gross
     margin in the fourth quarter of 1997. The Company is targeting a positive
     gross margin for the full year in 1998, as a result of new product
     introductions and continued reductions in unit product costs, stemming from
     increased sales volumes and further expected improvements in manufacturing
     yields, processes and costs.

     OPERATING EXPENSES  Total operating expenses for 1997 increased $1.6
     million or 9% compared to 1996, as a result of the inclusion of a full year
     of expenses for the operations of the Company's subsidiary, DML. Compared
     to pro forma combined Diametrics' and Biomedical Sensors' operating
     expenses for 1996, pre-restructuring operating expenses decreased 18% in
     1997 as a result of work force reductions and cost and process improvements
     implemented during the year. Operating expenses increased by $1.4 million
     or 9% from 1995 to 1996, due primarily to restructuring and other charges
     incurred during 1996 and the inclusion of approximately one month of
     expenses for the operations of DML.

     Research and development expenses increased $872,000 or 14% from 1996 to
     1997, after an increase of $249,000 or 4% from 1995 to 1996.  The increase
     in expense in 1996 reflects the inclusion of one month of expenses for the
     operations of DML.  Compared to pro forma combined Diametrics' and
     Biomedical Sensors' research and development expenses for 1996, expenses
     decreased 22% in 1997 as a result of work force reductions, 
<PAGE>
 
     primarily in the Company's U.S. operations, and cost and process
     improvements implemented during the year.

     Sales and marketing expenses totaled $7,893,284 in 1997, compared to
     $6,781,943 in 1996 and $5,801,363 in 1995. The 17% increase in expenses
     from 1995 to 1996 reflects costs to support the expansion of the Company's
     direct sales force in the U.S., higher commissions on increased sales and
     the inclusion of DML expenses from the date of acquisition. Compared to pro
     forma combined Diametrics' and Biomedical Sensors' sales and marketing
     expenses for 1996, expenses decreased 15% in 1997 due to organizational
     efficiencies and better deployment of resources.

     General and administrative expenses totaled $3,689,036 in 1997, compared to
     $3,242,320 in 1996 and $3,488,874 in 1995.  The 7% reduction in expenses
     from 1995 to 1996 primarily reflects the impact of work force reductions in
     the Company's U.S. operations in the last half of 1996, partially offset by
     the inclusion of DML expenses from the date of acquisition. Compared to pro
     forma combined Diametrics' and Biomedical Sensors' general and
     administrative expenses for 1996, expenses decreased 16% in 1997 as a
     result of additional work force reductions, primarily in the Company's U.S.
     operations,  and cost improvements implemented during the year.

     Restructuring and other charges totaled $463,816 in 1997, compared to
     $1,334,661 in 1996 and $391,834 in 1995. Charges in 1995 reflect severance
     costs associated with a management reorganization in late 1995. Charges in
     1996 consist of approximately $584,000 for severance costs related to
     continued restructuring of the management team in early 1996 and a work
     force reduction, $464,000 for the write-off of purchased in-process
     research and development created from the Biomedical Sensors acquisition,
     and $287,000 for the write-down of excess and obsolete equipment, resulting
     from the work force reductions and process changes. Charges in 1997 consist
     of severance costs associated with work force reductions, primarily in the
     Company's U.S. manufacturing, research and development and general and
     administrative areas, and $145,000 for the write-down of excess and
     obsolete equipment resulting from the work force reductions and further
     process changes.

     OTHER INCOME (EXPENSE)  Net other expense in 1997 was $526,962, compared to
     net other income of $207,117 in 1996 and $340,587 in 1995.  The Company
     realized interest income of $658,625 in 1997, compared to $929,603 in 1996
     and $1,148,352 in 1995.  The year-to-year decline reflects the impact of
     lower average cash balances in 1996 and 1997 as a result of the Company's
     higher level of financing activities during 1994 and 1995, and also due to
     a net use of cash in operations.

     Interest expense totaled $1,017,657 in 1997, compared to $607,342 in 1996
     and $550,607 in 1995.  The year-to-year increase primarily reflects
     interest accrued on a long-term note payable to Pfizer Inc. issued in
     connection with the Company's acquisition of Biomedical Sensors in November
     1996.


     NET LOSS  Net loss for the year ended December 31, 1997 was $21,036,543,
     compared to $23,575,094 in 1996 and $23,046,314 in 1995. Compared to pro
     forma combined Diametrics' and Biomedical Sensors' net loss for the year
     ended December 31, 1996, the net loss decreased 35% in 1997, before the
     impact of restructuring and other charges. The company is targeting
     continued improvement in the 1998 net loss relative to 1997.
<PAGE>
 
     LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1997, the Company had working capital of approximately
     $12.5 million, an increase of $5.9 million from the working capital of $6.6
     million reported at December 31, 1996.  The increase is primarily the
     result of the receipt of proceeds of approximately $26 million from the
     issuance of common stock from two private equity placements, warrant
     exercises and employee stock option and stock purchase plans, partially
     offset by capital purchases, debt payments and the net use of cash in
     operations during 1997. Through December 31, 1997, the Company raised
     approximately $114 million through the public and private sales of its
     equity securities and the issuance of convertible promissory notes, all of
     which have been repaid or converted into common stock.

     At December 31, 1997, the Company had property and equipment of
     $18,060,127, up from $16,295,952 at December 31, 1996, less accumulated
     depreciation of $10,674,155 and $8,008,200 at December 31, 1997 and 1996,
     respectively. The $1.8 million net increase in the cost of property and
     equipment is primarily the result of $3.0 million of capital additions,
     consisting primarily of investments in development and production
     equipment, and instruments for internal use in R&D and sales. Since its
     inception in 1990, the Company has financed approximately $5 million of
     capital additions through capital lease obligations. In 1998, the company
     expects capital expenditures and new lease commitments to approximate $2.4
     million, primarily reflecting investments to support new product
     development and production.

     In late 1996 and throughout 1997, the Company entered into long-term debt
     obligations of approximately $8.9 million.  The debt consists of a $7.3
     million senior secured fixed rate loan note issued to Pfizer in connection
     with the Company's acquisition of Biomedical Sensors and approximately
     $1,558,000 in notes payable for equipment financing.  The company's long-
     term debt and capital lease obligations require principal and interest
     repayments of approximately $1.9 million in 1998, $1.1 million in each of
     years 1999, 2000 and 2001, and $8.1 million in 2002.

     At December 31, 1997, the Company had U.S. net operating loss and research
     and development tax credit carryforwards for income tax purposes of
     approximately $91,000,000 and $900,000, respectively. Pursuant to the Tax
     Reform Act of 1986, use of the Company's net operating loss carryforwards
     are limited due to a "change in ownership." (See footnote 12 for further
     discussion and amount of limitation).

     The Company believes that currently available funds and cash generated from
     1998 revenues, supplemented by proceeds from employee stock plans, warrant
     exercises and asset based credit, will meet the Company's working capital
     needs through 1998. If results of operations or capital requirements vary
     materially from those currently planned, the company could require
     additional capital at an earlier time. As a result, the company has and
     will continue to evaluate raising additional capital through, but not
     limited to, alliances with strategic corporate partners and sales of equity
     or debt securities. While there can be no assurance that adequate funds
     will be available when needed or on acceptable terms, management believes
     that the company will be able to raise adequate funding as needed. the
     Company's long-term capital requirements will depend upon numerous factors,
     including the rate of market acceptance of the Company's products and the
     level of resources devoted to expanding the sales and marketing
     organization, manufacturing capabilities and research and development
     activities.

     YEAR  2000 COMPLIANCE

     The financial impact to the Company of year 2000 compliance has not been
     and is not expected to be material to the Company's financial position or
     results of operations in any given year. The Company's existing information
     system, consisting of hardware and software supplied by third parties, is
     year 2000 compliant. However, because most computer systems are by their
     nature, interdependent, it is possible that non-compliant third party
     computers could "reinfect" the Company's computer systems. The Company
     could be adversely affected by the year 2000 problem if it or unrelated
     parties fail to successfully address this problem. The Company intends to
     develop a plan to communicate with the unrelated parties, including its
     regulatory consultants with whom it deals, to coordinate year 2000
     compliance. The costs incurred in addressing year 2000 compliance will be
     expensed as incurred, in compliance with GAAP.

     Statements regarding the Company's expectations about new and existing
     products, future financial performance and other forward looking statements
     are subject to various risks and uncertainties, including, without
     limitation, demand and acceptance of new and existing products,
     technological advances and product obsolescence, competitive factors and
     the availability of capital to finance growth.  These and other risks are
     discussed in greater detail as an exhibit in the Company's Form 10-k filing
     with the U.S. Securities and Exchange Commission.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DESCRIPTION OF THE BUSINESS  Diametrics Medical, Inc. along with its
     subsidiary (the Company), is a medical device company engaged in the
     development, manufacture and commercialization of critical care blood and
     tissue analysis systems which provide immediate or continuous diagnostic
     results at the point of patient care.
 
     The Company markets its products primarily to health care organizations
     through a direct sales force in the United States, the United Kingdom and
     Germany and various distributors outside of these countries.
 
     PRINCIPLES OF CONSOLIDATION  The accompanying consolidated financial
     statements include the accounts of Diametrics Medical, Inc. and Diametrics
     Medical, Ltd., its wholly-owned subsidiary (the Company).  All material
     intercompany accounts and transactions have been eliminated.  The accounts
     of the foreign subsidiary have been consolidated since the date of
     acquisition.  The Company did not have any subsidiaries prior to 1996.
 
     TRANSLATION OF FOREIGN CURRENCIES  The financial statements of the
     Company's foreign subsidiary were translated in accordance with the
     provisions of Statement of Financial Accounting Standards (SFAS) No. 52.
     Under this Statement, all assets and liabilities are translated using
     period-end exchange rates and statements of operations items are translated
     using average exchange rates for the period.  The resulting translation
     adjustments are recorded as a separate component of shareholders' equity.
     Foreign currency transaction gains and losses are included in determining
     net income, but have not been material in any of the years presented.
 
     CASH AND CASH EQUIVALENTS  The Company considers highly liquid debt
     instruments purchased with an original maturity of three months or less to
     be cash equivalents.  At December 31, 1997, cash and cash equivalents
     consisted mainly of U.S. government money market funds and investment grade
     commercial paper.
 
     MARKETABLE SECURITIES  In accordance with the provisions of SFAS No. 115,
     Investment in Certain Instruments in Debt and Equity Securities,
     investments in marketable debt securities have been classified as held to
     maturity and are stated at amortized cost, which approximates estimated
     fair value.  At December 31, 1997, marketable securities consisted mainly
     of investment grade commercial paper, with original maturities ranging from
     three to five months.  These securities are classified as held-to-maturity
     because of the Company's intent and ability to hold its investments to
     maturity.
 
     INVENTORIES  Inventories are stated at the lower of cost or market using
     the first in, first out method.
 
     PROPERTY AND EQUIPMENT  Leasehold improvements are recorded at cost and
     amortized over the term of the underlying lease. Furniture and equipment
     are recorded at cost and depreciated on a straight-line basis over their
     estimated useful lives of 2 to 7 years. Maintenance and repairs are
     expensed as incurred.
 
     OTHER ASSETS  Other assets consist principally of goodwill representing
     purchased completed technology and other intangible assets resulting from
     the excess of the cost of 
<PAGE>
 
     a purchased business over the fair value of the net assets acquired.
     Goodwill is amortized using the straight-line method over five years. The
     recoverability of goodwill is assessed quarterly based upon an analysis of
     undiscounted cash flows projected to be generated by the acquired business.
 
     REVENUE RECOGNITION  The Company recognizes revenue upon shipment of
     product to customers or, in the case of trial instruments and monitors,
     upon the customer's acceptance of the product.
 
     NET LOSS PER COMMON SHARE  Effective December 31, 1997, the Company adopted
     SFAS No. 128, Earnings per Share.  SFAS 128 simplifies the computation of
     earnings per share ("EPS") previously required by replacing primary and
     fully diluted EPS with basic and diluted EPS.  Under SFAS 128, basic EPS is
     calculated by dividing net earnings (loss) by the weighted average common
     shares outstanding during the period.  Diluted EPS reflects the potential
     dilution to basic EPS that could occur upon conversion or exercise of
     securities, options, or other such items, to common shares using the
     treasury stock method based upon the weighted average fair value of the
     Company's common shares during the period.  For each period presented,
     basic and diluted loss per share amounts are identical, as the effect of
     potential common shares is antidilutive.
 
     PRODUCT WARRANTY  The Company, in general, warrants its new hardware and
     software products to the original purchaser to be free from defects in
     material and workmanship under normal use and service for a period of one
     year after date of shipment, and warrants its disposable products to be
     free from defect in material and workmanship under normal use until its
     stated expiration date.  Provisions are made for the estimated cost of
     maintaining product warranties for the hardware, software and disposable
     products at the time the products are sold.
 
     INCOME TAXES  Deferred tax assets and liabilities are recognized for the
     future tax consequences attributable to differences between the financial
     statement carrying amounts of existing assets and liabilities and their
     respective tax bases.  Deferred tax assets and liabilities are measured
     using enacted tax rates expected to apply to taxable income in the years in
     which those temporary differences are expected to be recovered or settled.
     The effect on deferred tax assets and liabilities of a change in tax rates
     is recognized in income in the period that includes the enactment date.
     Due to historical net losses of the Company, a valuation allowance is
     established to offset the net deferred tax asset.
 
     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.

     STOCK BASED COMPENSATION  The Company applies the intrinsic value method
     prescribed in APB Opinion No. 25 to account for the issuance of stock
     incentives to employees and directors and, accordingly, no compensation
     expense related to employees' and directors' stock incentives has been
     recognized in the financial statements.  Effective January 1, 1996, in
     accordance with SFAS No. 123, Accounting for Stock Based Compensation, pro
     forma information reflecting compensation cost for such issuances is
     presented in footnote 9.
<PAGE>
 
     RECLASSIFICATIONS  Certain 1996 and 1995 amounts in the Consolidated
     Statements of Operations have been reclassified from prior reported
     balances to conform to the 1997 presentation.
 
(2)  LIQUIDITY
 
     As reflected in the accompanying consolidated financial statements, the
     Company incurred a net loss of $21,036,543 for the year ended December
     31, 1997.  In addition, the Company has incurred net losses and has had
     negative cash flows from operating activities since inception. Management
     believes current working capital and projected operating revenues,
     supplemented by proceeds from employee stock plans, warrant exercises and
     asset based credit, will provide the Company with sufficient liquidity
     through 1998.  It is probable the Company will be required to raise
     additional capital by early 1999.  Management's intentions are to raise
     this additional capital through alliances with strategic corporate
     partners, issuance of debt, or an equity offering.  If capital requirements
     vary materially from those currently planned, the Company could require
     additional capital at an earlier time.  There can be no assurance that
     adequate funds will be available when needed or on acceptable terms.

     The senior secured fixed rate loan note of $7,300,000 is payable to Pfizer
     Inc., issued in connection with the Company's acquisition of Biomedical
     Sensors, Ltd. (BSL), an operating unit of Pfizer Inc., on November 6, 1996.
     Interest is payable on December 31, 1997 and quarterly in arrears
     thereafter, at 8.75% per annum. The full principal balance is due November
     4, 2002. The Pfizer note is secured by the issued shares of Diametrics
     Medical, Ltd., 100% of which were purchased by the Company.
 
     The note agreement with Pfizer Inc. contains provisions which will require
     acceleration of payment of principal in full in the event that prior to
     November 6, 1998, the Company issues securities listed or traded on any
     securities exchange, with aggregate net proceeds to the Company exceeding
     $40 million. If this doesn't occur, then, in the event the Company issues
     securities from November 6, 1998 to November 4, 2002 resulting in
     cumulative net proceeds of more than $5 million, a proportion of the
     outstanding principal balance shall become immediately payable. During this
     period, cumulative net proceeds from a securities issuance of more than $5
     million but less than $10 million would require a $1 million payment of
     principal, while cumulative net proceeds between $10 million and less than
     $20 million and between $20 million and less than $40 million would require
     principal payments of $2.5 million and $4.5 million, respectively.
     Cumulative net proceeds of $40 million or greater would require full
     payment of the note's principal.
 
     The notes payable balance requires principal and interest payments in
     monthly installments at varying amounts through September 2002, at annual
     interest rates ranging from 10.1% to 10.95%. Maturity dates of the notes
     range from December 1, 2001 to September 25, 2002, and all notes are
     secured by equipment.
 
(8)  LEASES
 
     The Company is obligated under various capital leases for furniture and
     equipment that expire at various dates during the next two years. The gross
     amount included in property and equipment and related accumulated
     amortization relating to capital leases is as follows:

(9)  STOCK OPTIONS AND WARRANTS

     Under the terms of the 1990 Stock Option Plan, incentive stock options and
     non-qualified stock options to purchase up to 3,000,000 shares of common
     stock may be granted to Company employees and consultants.
     
     Additionally, the Directors' Plan provides grants to non-employee directors
     of the Company of non-qualified stock options to purchase up to an
     aggregate of 217,500 shares of common stock.

     Under the plans, the option price is equal to the fair value on the date of
     grant. Under the 1990 Stock Option Plan, options become exercisable over
     varying periods and terminate up to ten years from the date of grant. Under
     the Directors' Plan, options become exercisable over a three year period
     and terminate ten years from the date of grant. At December 31, 1997,
     136,478 and 69,750 additional shares were available for grant under the
     1990 Stock Option Plan and Directors' Plan, respectively.
 
     The following tables reflect the per share weighted-average fair value of
     stock options granted during 1997, 1996 and 1995 under each of the plans on
     the date of grant using the Black Scholes option-pricing model with the
     following assumptions: annualized volatility of 74.15%, 70.81% and 80.04%
     for 1997, 1996 and 1995, respectively; risk-free interest rate of 5.7% in
     1997 and 5.5% in 1996 and 1995, respectively; and for each year, an
     expected life of five and three years for the 1990 Stock Option Plan and
     Directors' Plan, respectively.
 
     The status of the Company's stock option plans as of December 31, 1997,
     1996 and 1995 and changes during those years, is summarized as follows:

     The Company applies APB Opinion No. 25, Accounting for Stock Issued to
     Employees, and related interpretations in accounting for its plans.
     Accordingly, no compensation expense has been recognized for its stock-
     based compensation plans as they relate to employees and directors. Had the
     Company determined compensation cost based upon the fair value at the grant
     date for its stock options under SFAS No. 123, the Company's net loss and
     net loss per share would have increased to the pro forma amounts indicated

     Pro forma net loss reflects only options granted in 1997, 1996 and 1995.
     Therefore, the full impact of calculating compensation cost for stock
     options under SFAS No. 123 is not reflected in the pro forma net loss
     amounts presented, because compensation cost is reflected over the options'
     vesting period and compensation cost for options granted prior to January
     1, 1995 is not considered.
 
     In connection with certain financing and marketing arrangements, the
     Company has granted stock purchase warrants for the purchase of 2,305,394
     shares of common stock. The stock purchase warrants become exercisable over
     varying periods and expire up to 10 years from the date of grant. At
     December 31, 1997, stock purchase warrants representing 961,827 shares were
     exercisable with an additional 66,333 shares becoming exercisable on a
     monthly basis over 28 months (58,333 shares), or upon achieving certain
     purchasing levels of the Company's products (8,000 shares). Stock warrant
     transactions under these arrangements are summarized as follows:

(10) EMPLOYEE STOCK PURCHASE PLAN
 
     The Company adopted an employee stock purchase plan (the "Plan") effective
     July 3, 1995, under which 300,000 shares of common stock are available for
     sale to employees. The Plan enables all employees, after a 90-day waiting
     period, to contribute up to 10 percent of their wages toward the purchase
     of the Company's common stock at 85 percent of the lower of fair market
     value for such shares on the first business day of each quarter or the last
     business day of each quarter.
 
     Participant elections resulted in the issuance of 55,394 shares at an
     average price per share of $3.72 in 1997 and 74,096 shares at an average
     price per share of $4.06 in 1996.
 
(11) EMPLOYEE BENEFIT PLANS
 
     The Company has a 401(k) savings plan for its U.S. employees. U.S.
     employees of the Company who meet certain age and service requirements may
     contribute up to 20 percent of their salaries to the plan on a pre-tax
     basis. The Company has the discretion to match employee contributions up to
     6 percent of compensation. The Company has not made any contributions to
     the plan.
 
     As part of its acquisition of the England-based Biomedical Sensors, Ltd.
     (BSL) in November 1996, the Company assumed sponsorship of the subsidiary's
     contributory defined benefit retirement plan, covering the majority of the
     subsidiary's employees. The Plan provides benefits based upon final
     pensionable salary and years of credited service. The Company's funding
     policy for the Plan is to contribute into a trust fund at a rate that is
     intended to remain at a level percentage of total pensionable payroll. The
     assets of the Plan are held separately from those of the Company and
     invested in the London and Manchester Secure Growth Fund, Balanced Fund and
     a small holding in the Performance Fund. A portion of plan assets are also
     invested in the Scottish Equitable Funds.

     Contributions to the Plan are charged to expense so as to spread the cost
     of the pensions over the employees' working lives with the Company. The
     contributions are determined by a qualified actuary on the basis of a
     valuation using the "attained age" valuation method.

     The Company's Statement of Operations for the year ended December 31, 1996
     includes approximately one month of activity for DML, and pension expense
     charged to operations during that period was minimal. Following is the
     net periodic pension cost charged to operations in 1997, along with a
     description of the funded status of the Plan  
<PAGE>
 
     at December 31, and assumptions used in developing the projected benefit
     obligation as of December 31.

     The net pension liability recognized as of December 31, 1996 was part of a
     required purchase accounting fair value adjustment recorded upon the
     acquisition of BSL to reflect the U.K. to U.S. GAAP adjustment relating to
     the accounting for pension costs under the provisions of SFAS No. 87.

(12) INCOME TAXES
 
     The Company has incurred net operating losses since inception. The Company
     has not reflected any benefit of such net operating loss carryforwards in
     the accompanying financial statements in accordance with Statement of
     Financial Accounting Standards No. 109.
 
     As of December 31, 1997 the Company has U.S. tax net operating loss and
     research and development tax credit carryforwards of approximately
     $91,000,000 and $900,000, respectively. Pursuant to the Tax Reform Act of
     1986, use of the Company's net operating loss carryforwards may be limited
     if a cumulative "change in ownership" of
<PAGE>
 
     more than 50 percent occurs within a three-year period. In connection with
     prior sales by the Company of its securities in private and public
     offerings, the Company has experienced a "change in ownership". As a
     result, the utilization of the Company's net operating loss and certain
     credit carryforwards incurred prior to these changes are subject to annual
     limitations.
 
     The Company estimates that the use of the U.S. net operating losses
     incurred from January 26, 1990 (inception) through February 11, 1991 is
     limited to approximately $418,000 per year; the use of net operating losses
     incurred from February 12, 1991 through December 7, 1992 is limited to
     approximately $1.9 million per year. If not used, these net operating loss
     carryforwards begin to expire in 2005.
 
     The Company's foreign subsidiary also has a net operating loss carryforward
     of approximately $40,700,000 which can be carried forward indefinitely.
 
     The tax effects of temporary differences that give rise to significant
     portions of the deferred tax assets and deferred tax liabilities at
     December 31, 1997 and 1996 are as follows:

(13) RESTRUCTURING AND OTHER CHARGES
 
     In late 1995 and throughout 1996 and 1997, the Company made operational
     changes intended to better align its resources with its evolving strategy,
     improve its efficiency, and achieve a more competitive cost structure.
     Restructuring and other charges totaled $463,816 in 1997, $1,334,661 in
     1996 and $391,834 in 1995. Charges in 1995 reflect 
<PAGE>
 
     severance costs associated with a management reorganization in late 1995.
     Charges in 1996 consist of approximately $584,000 for severance costs
     related to continued restructuring of the management team in early 1996 and
     a work force reduction in November, $464,000 for the write-off of purchased
     in-process research and development created from the BSL acquisition, and
     $287,000 for the write-down of excess and obsolete equipment, resulting
     from the work force reductions and process changes. Charges in 1997 consist
     of severance costs of approximately $319,000, associated with work force
     reductions primarily in the Company's U.S. manufacturing, research and
     development and general and administrative areas, and $145,000 for the
     write-down of excess and obsolete equipment resulting from the work force
     reductions and further process changes. These restructuring activities were
     completed before or shortly after the end of the quarter of the years in
     which charges were incurred, and the Company does not have any material
     future cash obligations relative to the described restructuring activities.
     The impact of work force reductions on future operating results and cash
     flows is not expected to be material in the long term, as savings achieved
     in these areas have been and will continue to be reinvested in other areas
     of the Company, including the Company's international operations.
 
(14) RELATED PARTY TRANSACTIONS
 
     Certain equipment used by the Company was leased from late 1990 through mid
     1997 under a sublease arrangement with FIM, an entity that is related to
     the Company through stockholders. FIM leased the equipment from an
     unrelated entity. The Company paid FIM an amount equal to FIM's lease
     payments. The leases were accounted for as capital leases. As of December
     31, 1997, the debt related to the sublease with FIM was fully paid.
 
     Payments on leases of equipment, under the arrangement with FIM discussed
     above, were guaranteed up to a principal amount of approximately $1,300,000
     by Medical Innovation Fund, a holder of approximately 8% of the Company's
     common stock as of December 31, 1996.

(15) MAJOR CUSTOMERS, EXPORT SALES AND DOMESTIC AND FOREIGN OPERATIONS

     Sales to major customers that exceeded 10% of total net sales for the years
     ended December 31 were as follows:

     The customers from which the above sales were generated are distributors of
     the Company operating in the medical diagnostic device industry.
 
     The Company's export sales (i.e. sales to unaffiliated customers outside of
     the U.S.) were $6,487,079, $1,248,915 and $318,219 for the years ended
     December 31, 1997, 1996 and 1995, respectively. These sales were primarily
     in Europe and Japan.

     The Company did not have operations outside of the United States prior to
     1996.  The Company's European operations are primarily in the United
     Kingdom.  Sales and transfers between geographic areas primarily represent
     intercompany sales and are accounted for based upon established transfer
     prices between the related entities.  Identifiable assets of geographic
     areas are those assets related to the Company's operations in each area.
     United States assets include all of the Company's marketable securities.
 
(16) COMMITMENTS
 
     The Company leases its facilities and some of its equipment under non-
     cancelable operating lease arrangements.  The rental payments under these

(18) ACQUISITIONS
 
     On November 6, 1996, the Company acquired all the outstanding capital stock
     of Biomedical Sensors, Ltd. (BSL), an operating unit of Pfizer Inc. and
     certain assets from Howmedica, Inc. (a wholly-owned subsidiary of Pfizer
     Inc.), for $1,500,000 in cash and a $7,300,000 senior secured fixed rate
     loan note, due November 4, 2002 (see footnote 7).  In the purchase of BSL,
     the Company acquired fiberoptic and electrochemical technology for
     monitoring blood gases on a continual basis via sensors that dwell inside
     arterial lines.  Core technology was also purchased for future product
     derivatives under development.
 
     The Company accounted for the acquisition using the purchase method. As
     such, the excess of the purchase price over the fair value of the
     identifiable assets acquired was recorded as goodwill, which consisted of
     purchased completed technology (70%), purchased in-process technology
     (16%), and the value of the acquired customer base and other unidentifiable
     intangible assets (14%), totaling $2,770,359.  The in-process technology
     ($464,460) was written off to operating expenses, leaving $2,305,899 of
     goodwill on the balance sheet at the acquisition date.  Due to the rapid
     pace of technological change in the medical device industry, the completed
     technology has an estimated life of five years.  The customer base and
     other unidentifiable assets is estimated to have an average useful life of
     five years.  This results in a weighted average amortization period of five
     years for the intangible assets not immediately written off.
 
     The unaudited pro forma consolidated condensed results of operations for
     the Company for fiscal years 1996 and 1995, had the acquisition occurred at
     the beginning of each fiscal year presented, are as follows:

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

management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present

     CAUTIONARY FACTORS UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT

Diametrics Medical, Inc. (the "Company") desires to take advantage of the "safe
harbor" provisions contained in the Private Securities Litigation Reform Act of
1995 (the "Act"). Contained in this Form 10-K are statements which are intended
as "forward-looking statements" within the meaning of the Act. The words or
phrases "expects," "will continue," "is anticipated," "management believes,"
"estimate," "projects," "hope" or expressions of a similar nature denote 
forward-looking statements. Those statements are subject to certain risks and
uncertainties that could cause actual results to differ materially from
historical results or from those results presently anticipated or projected. The
Company wishes to caution readers not to place undue reliance on forward-looking
statements. Readers should be advised that the factors listed below have
affected the Company's performance in the past and could affect future
performance. Those factors include, but are not limited to, the lack of, or slow
rate of, market acceptance of the Company's products; the impact of competitors'
products and pricing; the effect of changes in customer demands; the risk there
will be technical difficulties in production; and the inability of the Company
to attract and retain skilled employees in the product development and
manufacturing areas.

Other factors include the following:

EARLY STAGE OF COMMERCIALIZATION; LIMITED RELEVANT OPERATING HISTORY

The Company was founded in 1990 and until 1995 was engaged primarily in the
research, development and testing of, and the development of manufacturing
capabilities for, the IRMA(R) (Immediate Response Mobile Analysis) System and
the Paratrend(R) 7. Marketing efforts began for both products during 1994. The
Company has limited operating history upon which an evaluation of its prospects
can be made. Such prospects must be considered in light of the risks, expenses
and difficulties frequently encountered in establishing a new business in the
evolving, heavily-regulated medical device industry, which is characterized by
an increasing number of entrants, intense competition and a high failure rate.

ABSENCE OF PROFITABILITY; ANTICIPATED FUTURE LOSSES

The Company has only recently begun to generate revenues and has incurred net
operating losses since its inception.  Net losses for the years ended
December 31, 1997, 1996 and 1995 were approximately $21,037,000, $23,575,000 and
$23,046,000, respectively.  The Company had an accumulated deficit of
approximately $101,056,000 at December 31, 1997.  The Company expects to incur
substantial net operating losses at least through 1998.  There is no assurance
that the Company will ever generate substantial revenues or achieve
profitability.

NEW TECHNOLOGY; UNCERTAIN MARKET ACCEPTANCE

The Company's success is dependent upon acceptance of its products by the
medical community as reliable, accurate and cost-effective. Because the products
are point of care blood testing and monitoring devices, they represent a new
practice in the analysis of blood analytes.  Critical or stat blood testing is
currently performed primarily by central and stat laboratories of hospitals or
by independent commercial laboratories, rather than at the point of care.
Although professional awareness of point of care blood testing is increasing,
most acute care hospitals have already installed costly benchtop blood testing
instruments for use in their central and stat laboratories and may be reluctant
to change standard operating procedures for performing blood analysis or incur
additional capital expenditures for new blood analysis equipment.  In addition,
the limited number of analytes that can be analyzed on the products may cause
certain hospitals not to consider them.  The Company is unable to predict how
quickly, if at all, the products will be accepted by members of the medical
community or, if accepted, what the utilization of disposable cartridges and
sensors may 
<PAGE>
 
be. Therefore, the Company is unable to provide any assurance as to sales volume
of the products or the related disposable cartridges and sensors.

FUTURE ADDITIONAL CAPITAL REQUIREMENTS

The Company expects that its existing capital resources, warrant and stock
option exercises, future equipment financing and asset based credit
arrangements, and strategic alliances will enable the Company to maintain its
current and planned operations through 1998. Nonetheless, the Company's capital
requirements depend on numerous factors, including the rate of market acceptance
of the Company's products, the level of resources devoted to expanding the
Company's marketing organization and manufacturing capabilities, the Company's
research and development activities, the availability of financing for capital
acquisitions and other factors. The timing and amount of such capital
requirements cannot accurately be predicted. If capital requirements vary
materially from those currently planned, the Company will require additional
capital at an earlier time. The Company has no commitments for any additional
financing, and no assurance exists that any such commitments can be obtained on
favorable terms, if at all. Any additional equity financings may be dilutive to
shareholders, and debt financing, if available, may involve restrictive
covenants. The Company is also pursuing corporate strategic alliances. Such
alliances may require the Company to relinquish rights to certain of its
technologies, products or marketing territories.

HIGHLY COMPETITIVE MARKETS; RISK OF TECHNOLOGICAL OBSOLESCENCE

The medical technology industry is characterized by rapidly evolving technology
and intense competition. The Company is aware of one other commercially
available hand-held point of care blood analysis system, which is manufactured
and marketed by i-STAT Corporation ("i-STAT"). The Company expects that
manufacturers of central and stat laboratory testing equipment will also compete
to maintain their revenues and market share. Many of the companies in the
medical technology industry and manufacturers of central and stat laboratory
equipment have substantially greater capital resources, research and development
staffs and facilities than the Company. Such entities have developed, may be
developing or could in the future attempt to develop additional products
competitive with the Company's. Many of these companies also have substantially
greater experience than the Company in research and development, obtaining
regulatory approvals, manufacturing, and sales and marketing, and may therefore
represent significant competition. There can be no assurance that the Company's
competitors will not succeed in developing or marketing technologies and
products that are more effective or less expensive than those developed or
marketed by the Company or that would render the Company's technology and
products obsolete or noncompetitive. Although the Company believes that its
products may offer certain technological advantages over its competitors'
currently-marketed products, earlier entrants in the market in a therapeutic
area often obtain and maintain significant market share relative to later
entrants. In the future, the Company may experience competitive pricing
pressures that may adversely affect unit prices and sales levels.

LIMITED MANUFACTURING EXPERIENCE

The Company must manufacture its products in compliance with regulatory
requirements, in sufficient quantities and on a timely basis, while maintaining
product quality and acceptable manufacturing costs. The products consist of two
principal components: portable, microprocessor-based instruments and disposable
sensors. The Company has limited experience producing in large commercial
quantities. Although the Company believes that, based on its manufacturing
experience to date, it will be able to achieve and maintain product accuracy and
reliability when producing in the quantities required for profitable operations,
on a timely basis and at an acceptable cost, there can be no assurance that it
will be able to do so. The instruments are manufactured for the Company by
outside vendors, and there can be no assurance that such vendors will be able to
provide the Company with a sufficient quantity to meet the Company's needs.

DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY

The Company's success will depend in part on its ability to obtain patent
protection for products and processes, to preserve its trade secrets and to
operate without infringing the proprietary rights of third parties. The validity
and breadth of claims covered in medical technology patents involves complex
legal and factual questions and, therefore, may be highly uncertain. No
assurance can be given that any patents under pending patent applications or any
future patent applications will be issued, that the scope of any patent
protection will exclude competitors or provide competitive advantages to the
Company, that any of the Company's patents will be held valid if subsequently
challenged or that others will not claim rights in or ownership to the patents
and other proprietary rights held by the Company. Furthermore, there can be no
assurance that others have not developed or will not develop similar products,
duplicate any of the Company's products or, if patents are issued to the
Company, design around such patents. In addition, whether or not the Company's
patents are issued, others may hold or receive patents which contain claims
having a scope that covers products developed by the Company. The Company also
relies upon unpatented trade secrets to protect its proprietary technology, and
no assurance can be given that others will not independently develop or
otherwise acquire substantially equivalent techniques or otherwise gain access
to the Company's proprietary technology or disclose such technology or that the
Company can ultimately protect meaningful rights to such unpatented proprietary
technology.

RISK OF PATENT LITIGATION

There has been substantial litigation regarding patent and other intellectual
property rights in the medical device industry. Litigation, which could result
in substantial cost to and diversion of effort by the Company, may be necessary
to enforce patents issued to the Company, to protect trade secrets or know-how
owned by the Company, to defend the Company against claimed infringement of the
rights of others or to determine the ownership, scope or validity of the
proprietary rights of the Company and others. An adverse determination in any
such litigation could subject the Company to significant liabilities to third
parties, could require the Company to seek licenses from third parties and could
prevent the Company from manufacturing, selling or using its products, any of
which could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company is not currently a party to any
patent litigation.

DEPENDENCE ON MANAGEMENT AND OTHER KEY PERSONNEL

The success of the Company and of its business strategy is dependent in large
part on the ability of the Company to attract and retain key management and
operating personnel. Such individuals are in high demand and are often subject
to competing offers. In addition, the Company will have an ongoing need to
expand its management personnel and support staff. The loss of the services of
one or more members of the management group or the inability to hire additional
personnel as needed may have an adverse effect on the Company.

UNCERTAINTY OF GOVERNMENT HEALTH CARE POLICY AND FUTURE REIMBURSEMENT

The willingness of hospitals to purchase the Company's products may depend on
the extent to which hospitals limit capital expenditures due to cost
reimbursement regulations, including regulations promulgated by the Health Care
Financing Administration ("HCFA"), and general uncertainty relating to
government health care policy. In addition, sales volumes and prices of the
Company's products in certain markets will be dependent in part on the level of
availability of reimbursement to hospitals for blood analysis from third-party
payors, such as government and private insurance plans, health maintenance
organizations and preferred provider organizations. There can be no assurance
that current reimbursement amounts, if any, will not be decreased in the future,
and that any such decrease will not reduce the demand for or the price of the
Company's products. Any health care reform measures adopted by the federal
government could adversely affect the price of medical devices in the United
States or the amount of reimbursement available, and consequently could be
<PAGE>
 
adverse to the Company. No prediction can be made as to the outcome of any
reform initiatives or their impact on the Company.

GOVERNMENT REGULATION AND NEW PRODUCT DEVELOPMENT

Human diagnostic products are subject, prior to clearance for marketing, to
rigorous pre-clinical and clinical testing mandated by the United States Food
and Drug Administration (the "FDA") and comparable agencies in other countries
and, to a lesser extent, by state regulatory authorities. The Company has
obtained pre-market notification clearances under Section 510(k)
("Section 501(k)") of the Food, Drug and Cosmetic Act (the "FDC Act") to market
the IRMA SL System to test blood gases, electrolytes and hematocrit in whole
blood in hospital laboratories and at the point of care and the Paratrend 7 and
Paratrend 7+ to monitor blood gases. In early 1998 additional pre-market
notifications were obtained for the addition of glucose testing capability to
the IRMA SL System, and Neotrend for blood gas monitoring of critically ill
neonates. A 510(k) clearance is subject to continual review and later discovery
of previously unknown problems may result in restrictions on the product's
marketing or withdrawal of the product from the market. The Company's long-term
business strategy includes development of cartridges and sensors for performing
additional blood and tissue chemistry tests, and any such additional tests will
be subject to the same regulatory process. No assurance can be given that the
Company will be able to develop such additional products or uses on a timely
basis, if at all, or that the necessary clearances for such products and uses
will be obtained by the Company on a timely basis or at all, or that the Company
will not be subjected to a more extensive prefiling testing and FDA approval
process. The Company also plans to market its products in several foreign
markets. Requirements vary widely from country to country, ranging from simple
product registrations to detailed submissions such as those required by the FDA.
Manufacturing facilities are also subject to FDA inspection on a periodic basis
and the Company and its contract manufacturers must demonstrate compliance with
current Good Manufacturing Practices ("GMP") promulgated by the FDA. The Company
will be required to expend time, resources and effort in the areas of production
and quality control to ensure full technical compliance. If violations of the
applicable regulations are noted during FDA inspections of the Company's
manufacturing facilities or the manufacturing facilities of its contract
manufacturers, the continued marketing of the Company's products may be
adversely affected.

EFFECT OF CLINICAL LABORATORY IMPROVEMENT ACT OF 1988

The Company's products are affected by the Clinical Laboratory Improvement
Amendment of 1988 ("CLIA") which has been implemented by the FDA. This law is
intended to assure the quality and reliability of all medical testing in the
United States regardless of where tests are performed. The regulations require
laboratories performing blood chemistry tests to meet specified standards in the
areas of personnel qualification, administration, participation in proficiency
testing, patient test management, quality control, quality assurance and
inspections. The regulations have established three levels of regulatory control
based on test complexity - "waived," "moderate complexity" and "high
complexity." Although the tests performed by the products have been categorized
as moderate complexity tests, there can be no assurance that they will continue
to be so categorized. Personnel standards for high complexity tests are more
rigorous than those for moderate complexity tests, requiring that testing
personnel have more education and experience than personnel conducting moderate
complexity tests. Any recategorization of the tests performed by the Company's
products as high complexity tests could affect the Company's ability to
successfully market them. As a result of the CLIA requirements, hospitals may be
discouraged from expanding point of care analysis and previously unregulated
testing markets, including physician office laboratories and small volume test
sites, and may be dissuaded from initiating, continuing or expanding patient
testing. There can be no assurance that the CLIA regulations or future
administrative interpretations of CLIA or various state regulations requiring
licensed technicians to operate point of care devices will not have a material
adverse effect on the Company.

PRODUCT LIABILITY RISK; NO ASSURANCE INSURANCE IS ADEQUATE

The Company faces an inherent business risk of exposure to product liability
claims in the event that the use of its products is alleged to have resulted in
adverse effects to a patient. Although the Company has not experienced any
product liability claims to date, any such claims could have an adverse impact
on the Company. The Company maintains a general insurance policy which includes
coverage for product liability claims. The policy is limited to a maximum of
$1,000,000 per product liability claim and an annual aggregate policy limit of
$2,000,000. The Company also carries umbrella liability insurance which provides
coverage up to $10,000,000. There can be no assurance that liability claims will
not exceed the coverage limits of such policies or that such insurance will
continue to be available on commercially reasonable terms or at all.
Consequently, a product liability claim or other claim with respect to uninsured
liabilities or in excess of insured liabilities could have a material adverse
effect on the Company.

DEPENDENCE ON CONTRACT MANUFACTURERS AND SUPPLIERS

The Company's instruments, both monitors and IRMA analyzers, are manufactured
for the Company by single vendors, generally from off-the-shelf components. A
few components are supplied by a single source and manufactured to the Company's
specifications. Although the Company believes that it could find alternative
vendors, any interruption in supply could have a material adverse effect on the
Company. Although the Company believes that alternative sources for key
components are available, any interruption in supply of these components could
have a material adverse effect on the Company's ability to manufacture its
products.

CONTROL BY EXISTING SHAREHOLDERS

As of December 31, 1997, directors, executive officers and principal
shareholders of the Company, and certain of their affiliates, owned beneficially
approximately 30% of the Company's outstanding Common Stock. Accordingly, these
shareholders, individually and as a group, may be able to influence the outcome
of shareholder votes, including votes concerning the election of directors,
adopting or amending provisions in the Company's Articles of Incorporation and
Bylaws and approving certain mergers or other similar transactions, such as
sales of substantially all of the Company's assets. Such control by existing
shareholders could have the effect of delaying, deferring or preventing a change
in control of the Company.

POSSIBLE VOLATILITY OF STOCK PRICE IN THE PUBLIC MARKET

The securities markets have from time to time experienced significant price and
volume fluctuations that may be unrelated to the operating performance of
particular companies. The market prices of the common stock of many publicly
traded medical device companies have in the past been, and can in the future be
expected to be, especially volatile. Announcements of technological innovations
or new products by the Company or its competitors, developments or disputes
concerning patents or proprietary rights, regulatory developments and economic
and other external factors, as well as period-to-period fluctuations in the
Company's financial results, may have a significant impact on the market price
of the Common Stock. Sales of Common Stock in the public market could adversely
affect prevailing market prices.
<PAGE>
 
POSSIBLE ISSUANCES OF PREFERRED STOCK; ANTI-TAKEOVER EFFECT OF MINNESOTA LAW

The Board of Directors has authority to issue up to 5,000,000 shares of
preferred stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of those shares without any further vote or action by
the shareholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any preferred
stock that may be issued in the future. The issuance of preferred stock could
have the effect of delaying, deferring or preventing a change in control of the
Company. In addition, certain provisions of Minnesota law applicable to the
Company could have the effect of discouraging certain attempts to acquire the
Company which could deprive the Company's shareholders of opportunities to sell
their shares of Common Stock at prices higher than prevailing market prices.
