                                        PART I

ITEM 1.  BUSINESS.

(a) GENERAL DEVELOPMENT OF BUSINESS.

    AVECOR Cardiovascular Inc. (the "Company") designs, develops, manufactures
and markets specialty medical devices for heart/lung bypass surgery and
long-term respiratory support. The Company's products include the AFFINITY
microporous, hollow fiber membrane oxygenator and related blood reservoirs, a
line of solid silicone membrane oxygenators and related blood reservoirs, the
MYOTHERM cardioplegia delivery system, SIGNATURE custom tubing packs and the
AFFINITY arterial filter.

    The Company was incorporated in Minnesota in December 1990 and began
operations in 1991 when it purchased the surgical division of SCIMED Life
Systems, Inc. (the "Predecessor Business"). The assets purchased included a line
of solid silicone membrane oxygenators.  The Company introduced its MYOTHERM
cardioplegia delivery system in October 1991, and began marketing its SIGNATURE
custom tubing packs in July 1993 upon the receipt of marketing clearance from
the U.S. Food and Drug Administration (the "FDA").  Also in July 1993, the
Company began international marketing of the AFFINITY oxygenator. In November
1993, the Company received marketing clearance from the FDA to begin U.S.
marketing of the AFFINITY oxygenator, and the Company released the device to the
U.S. market in February 1994. In July 1994, the Company received marketing
clearance from the FDA to market its AFFINITY blood reservoirs.  The Company
received marketing clearance from the FDA to market its AFFINITY arterial filter
in October 1995, which it released worldwide in the first quarter of 1996.  In
connection with the Company's continuing efforts to offer a more complete line
of proprietary heart/lung bypass circuit products, the Company is currently
completing development of a new blood pump, for which a 510(k) pre-market
notification was filed with the FDA in September 1996.

    In April 1992, the Company completed a public offering of 1,988,250 shares
of its Common Stock, $.01 par value ("Common Stock"), and received approximately
$9,700,000 in net proceeds after deducting expenses of the offering. On December
1, 1992, the Company acquired all of the issued and outstanding shares of the
capital stock of Cardio Med Ltd., a corporation organized under the laws of
England and Wales ("Cardio Med"), in exchange for 160,000 shares of the
Company's Common Stock. Cardio Med had been a distributor of the Company's
disposable membrane oxygenators, cardiotomy reservoirs and cardioplegia systems
and manufactured its own proprietary line of custom tubing packs.  As a result
of the


                                          1

<PAGE>

acquisition, Cardio Med has become a wholly-owned subsidiary of the Company.
Cardio Med's name has since been changed to AVECOR Cardiovascular Ltd. ("AVECOR
Ltd.").

    In June 1995, the Company completed a public offering of 1,161,250 shares
of Common Stock, resulting in net proceeds to the Company of approximately
$12,653,000.  An additional 1,478,000 shares of Common Stock were also sold by
certain shareholders of the Company in the offering.  During 1995, the Company
also incorporated AVECOR Foreign Sales Corporation as a wholly-owned subsidiary
of the Company and opened a sales office in France, which is organized as a
subsidiary of AVECOR Ltd.
    
    As used herein, the term "Company" refers to AVECOR Cardiovascular Inc.,
AVECOR Ltd., AVECOR Cardiovascular France S.A.R.L. and AVECOR Foreign Sales
Corporation.  The Company's principal executive offices are located at 7611
Northland Drive, Minneapolis, Minnesota 55428, and its telephone number is (612)
391-9000. 

(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS.

    Since its inception, the Company has operated in the single industry
segment of designing, developing, manufacturing and marketing medical devices. 

(c) NARRATIVE DESCRIPTION OF BUSINESS.

INDUSTRY BACKGROUND AND MARKETS

    INDUSTRY BACKGROUND.  The Company's products are used in surgical
procedures requiring heart/lung bypass, such as the treatment of coronary artery
disease by coronary artery bypass graft surgery ("CABG" or "coronary bypass
surgery"), heart valve replacement surgery and pediatric and neonatal congenital
heart defect surgery.  There were approximately 850,000 heart/lung bypass
procedures performed worldwide in 1995.  Approximately 400,000 heart/lung bypass
procedures were performed in the United States in 1995, and approximately
265,000 heart/lung bypass procedures were performed in Europe in 1994. Certain
of the Company's products are also used in non-surgical applications, such as
the long-term cardiopulmonary support of premature infants, newborns and other
patients with life-threatening respiratory disorders. 

    The primary use of the Company's products is for heart/lung bypass
procedures during the surgical treatment of coronary artery disease. Coronary
artery disease, the leading cause of death in the United States, is the
atherosclerotic narrowing of the coronary arteries that supply blood to the
heart. Atherosclerosis is the accumulation of cholesterol and blood products on
the inner lining of an artery that causes the arterial wall to thicken and lose
elasticity, narrowing the inner diameter of the artery. According to an estimate
by the American Heart Association, approximately 13,490,000 Americans have a
history of heart attack, angina pectoris (chest pain), or both, which are
generally associated with coronary artery disease. The American Heart
Association estimated that coronary artery disease would result in 1,500,000
acute myocardial infarctions, or heart attacks, in the United States in 1996, of
which approximately 500,000 would result in death. 

    In the late 1960s, cardiovascular surgeons pioneered coronary bypass
surgery, a surgical treatment for severe cases of coronary artery disease in
which blood vessel grafts are used to bypass the site of the blocked arteries.
Several of these procedures or "grafts" may be performed during a single surgery
in order to bypass atherosclerotic lesions in more than one of the coronary
arteries, which is commonly referred to as "multi-vessel" coronary artery
disease. Coronary bypass surgery generally requires that the patient be put on a
heart/lung bypass circuit to enable the surgeon to operate on a still,
relatively bloodless heart.  The


                                          2

<PAGE>

heart/lung bypass circuit is a series of interconnected specialty medical
devices that together function as a patient's heart and lungs by temporarily
oxygenating and circulating blood while the patient's own heart and lungs are
rendered inactive. The Company believes coronary bypass surgery accounts for
approximately 75% of the total heart/lung bypass procedures performed in the
United States and over 50% of the procedures performed in Europe. 

    Although coronary bypass surgery is a highly invasive procedure, it has
been shown to be highly effective in treating coronary artery disease, and the
number of procedures performed annually in the United States has grown from
approximately 200,000 in 1982 to over 400,000 in 1995 (multiple procedures may
be performed during a single surgery where multi-vessel disease is present). 
The annual worldwide growth rate in the number of coronary bypass procedures has
fluctuated from year to year for various reasons. 

    Since the development of coronary bypass surgery, a number of non-surgical
interventional treatments for coronary artery disease have been developed which,
depending on the extent and nature of the disease as well as physician
preference, may be used as an alternative to coronary bypass surgery. These
non-surgical treatments, while generally less costly per procedure, have
limitations and to date have not resulted in reduced demand for coronary bypass
surgery. 

    Percutaneous transluminal coronary angioplasty ("PTCA") was introduced in
the early 1980s as a non-surgical treatment for coronary artery disease. PTCA is
performed by guiding a balloon-tipped catheter to the site of an atherosclerotic
lesion, followed by several courses of dilation under high balloon pressure. For
many patients, PTCA represents a less costly and less traumatic alternative to
bypass surgery, while for other patients it represents a preferred alternative
to drug therapy.  While the number of PTCA procedures performed grew
significantly in the 1980s and early 1990s, the number of coronary bypass
procedures performed annually also continued to grow during this period.  

    Although the average cost of a PTCA procedure is approximately one-half of
the average cost of coronary bypass surgery, the need for further interventions
for many patients tends to significantly reduce the long-term cost differential
between these two types of procedures.   Studies have indicated that 30% to 50%
of PTCA procedures are complicated by "restenosis," a renarrowing, or often
reclosure, of the dilated vessel within six months.  An artery complicated by
restenosis often requires repeat procedures, reducing the overall
cost-effectiveness of PTCA.  For a significant number of PTCA patients, coronary
bypass surgery is ultimately performed.  In patients with multi-vessel coronary
artery disease, a randomized study has shown that within three years of
receiving treatment, only 14% of patients receiving coronary bypass surgery
required retreatment ("revascularization") while 60% of patients receiving PTCA
required revascularization.  Additional studies have confirmed that
approximately 20% of PTCA patients with multi-vessel disease will undergo
coronary bypass surgery within one year of receiving PTCA.  Because of the
higher rates of revascularization of patients receiving PTCA rather than
coronary bypass surgery, several studies have concluded that over a three-year
period the overall average cost of PTCA procedures exceeds 75% of the average
cost of coronary bypass surgery. 

    In response to the limitations of PTCA, a variety of "second generation"
interventional devices for coronary artery disease have been developed,
including atherectomy devices (catheter devices that cut and remove
atherosclerotic materials from the arterial wall), rotational ablation devices
(catheter devices which use a rotating burr to remove material), laser catheter
devices (devices that use laser energy to reduce accumulated materials in
arteries) and coronary stents (expandable metal frames that are positioned
within the diseased area in the coronary artery to maintain the vessel opening).
Of these devices, coronary stents have demonstrated the best potential to date
to reduce restenosis in a randomized population.  Recent studies have concluded
that the rate of restenosis in patients receiving coronary stents following PTCA
is


                                          3

<PAGE>

approximately 30% lower than in patients treated only by PTCA.  However, the use
of stenting in connection with PTCA greatly increases the cost of the PTCA
procedure.  One study has indicated that the average cost per procedure for
elective stenting in connection with PTCA was approximately twice the cost of
PTCA without stenting (or approximately equal to the cost of coronary bypass
surgery). 

    In addition to the existing non-surgical treatments for coronary artery
disease, an additional treatment modality has emerged for both coronary artery
disease and heart valve replacement procedures (discussed below), which involves
"least" or "minimally" invasive surgical procedures.  These techniques involve
small surgical incisions in the patient's chest in lieu of the larger incision
used in traditional CABG or valve replacement surgeries.  Specialized surgical
instruments used in connection with endoscopes enable surgeons to perform CABG
or valve replacement surgeries via these smaller incisions.  In some variations
of this type of procedure, only a modified form of the heart/lung bypass circuit
is required, which includes an oxygenator and related disposables.  However, in
other variations of this type of procedure a heart/lung bypass circuit is not
utilized.

    While this modality is in its developmental stages and currently requires
significant surgical skill and training, the potential benefits to patients from
this type of surgery are a reduced recovery period and risk of infection as a
result of the smaller incision.  While some of the patients currently eligible
for treatment by these types of procedures are not candidates for more invasive
and less costly procedures, there can be no assurance that this type of surgical
procedure will not represent a significant portion of the CABG or heart valve
replacement procedures in the future.  Therefore, it cannot be determined at
this time what effect, if any, the development and acceptance of these
procedures may have on the market for the Company's disposable heart/lung bypass
circuit components.

    A second significant use of the Company's products in conjunction with
heart/lung bypass procedures is in heart valve replacement surgery.  Heart valve
replacement surgery is also an open heart surgical procedure, involving the
replacement of valves that regulate the flow of blood between chambers in the
heart.  Valve replacement may be required where the valve has become narrowed or
ineffective due to the build-up of calcium or scar tissue, or where there is a
congenital defect or some other form of physical damage to the valve.  Like
coronary bypass surgery, valve replacement surgery requires that the patient be
put on a heart/lung bypass circuit.  The Company believes approximately 20% of
the heart/lung bypass procedures performed in the United States were performed
in heart valve replacement surgery and approximately 25% of the heart/lung
bypass procedures performed in Europe were performed in heart valve replacement
surgery. 

    Pediatric and neonatal congenital heart defect surgery is another
heart/lung bypass procedure which uses several of the Company's products.  These
procedures are undertaken to correct developmental defects in the heart of a
child or infant.  The Company believes approximately 5% of the heart/lung bypass
procedures performed in the United States and approximately 10% of those
performed in Europe were performed in connection with this type of corrective
surgery. 

    The primary non-surgical use of the Company's products is in connection
with a procedure known as extracorporeal membrane oxygenation ("ECMO").  ECMO is
the long-term cardiopulmonary support of premature infants, newborns and other
patients with life threatening respiratory disorders.  The relatively small ECMO
market served by the Company is comprised of 112 established centers worldwide,
in which approximately 1,300 neonatal ECMO procedures (procedures performed on
children younger than one year) were performed in 1993.  Neonatal ECMO
procedures constitute the vast majority of all ECMO procedures performed.  There
has been relatively little growth in the overall ECMO market in recent years and
the Company believes growth in this market will remain limited until technology
overcomes complications that


                                          4

<PAGE>

are common in long-term respiratory support, such as intracranial bleeding due
to the associated long-term use of anti-coagulants.  Since the Company
manufactures what it believes to be the only oxygenator that has received
clearance from the FDA for sale for long-term cardiopulmonary support for
periods greater than 24 hours, the Company believes it has a competitive
advantage in this relatively small market. 

    HEART/LUNG BYPASS CIRCUIT.  In procedures requiring cardiopulmonary
support, the patient is connected to a series of interconnected specialty
medical devices, collectively called a heart/lung bypass circuit.  The
heart/lung bypass circuit functions as the patient's heart and lungs by
temporarily oxygenating and circulating blood while the patient's own heart and
lungs are rendered inactive.  The devices in the heart/lung bypass circuit are
operated by a skilled medical professional known as a perfusionist, under the
direction of a surgeon.  The primary components of a heart/lung bypass circuit,
including the oxygenator, are single-use, disposable products.  Heart/lung
bypass circuits are customized for the particular practices of individual
perfusionists. 

    In a typical heart/lung bypass procedure, blood is removed via surgically
inserted "cannulae" (hollow tubes with specifically designed tips that
facilitate the drainage or infusion of blood into or out of a patient's body)
from the patient's vena cava (the large vessels leading to the heart).  The
blood flows from the patient's vena cava by gravity into a venous blood
reservoir where it is collected and "de-bubbled" (air is eliminated from the
blood).  In addition, blood that is suctioned from the patient or drained from
the heart is filtered and de-bubbled through a cardiotomy reservoir.  This blood
is then also added to the venous blood reservoir.  From the venous blood
reservoir, the blood is mechanically pumped by a blood pump serving as a
replacement for the patient's heart through an oxygenator.  The oxygenator
serves as a replacement for the patient's lungs by removing carbon dioxide from
and adding oxygen to the blood. The carbon dioxide and oxygen levels in the
blood are monitored with blood gas monitoring equipment, allowing the
perfusionist to make the proper adjustments to maintain the correct
concentrations.  The oxygenator also controls the temperature of the blood by
means of an integral heat exchanger connected to a heater-cooler console.  The
oxygenated blood is then returned to the patient through a final (arterial)
filter that removes any potential air or small particles.  This artificial
heart/lung system is the primary component of the bypass circuit. 

    In addition to the artificial heart/lung system, most bypass circuits also
include a cardioplegia delivery system.  During most cardiac surgical
procedures, the heart is stopped (arrested) to provide the surgeon with a
motionless field for the delicate surgery.  When this occurs, the heart muscle
receives very little blood supply.  A cardioplegia system infuses specially
formulated solutions (which often include oxygenated blood) directly into the
patient's coronary arteries.  In addition to delivering nutrients to the heart,
these solutions are also used to arrest the heart and maintain prescribed
temperatures. 

    In order to salvage the patient's own blood during surgery, a cell-saver
circuit may be used to collect and concentrate the patient's blood into washed,
packed cells which can be reinfused at a later time to improve the patient's red
blood cell count without the risks associated with donated blood.  Another
method of concentrating the patient's red blood cells is with the use of a
hemoconcentrator.  This device removes excess fluid from the patient's blood
(concentrating the red blood cells) and also preserves the plasma of the blood
that is generally discarded with typical blood cell salvaging. 

    The heart/lung bypass circuit is completed by connecting all of the devices
with tubing.  Frequently, this tubing is pre-connected according to the
instructions of individual perfusionists with all or some of the devices in the
circuit and marketed as custom tubing packs.  Increasingly, all of the
components in the heart/lung bypass circuit are assembled and packaged in a
complete, single container for a single heart/lung bypass procedure. 


                                          5

    MARKETS.  The Company's products are primarily sold to hospitals that
perform heart/lung bypass surgery.  There were approximately 1,000 hospitals in
the United States and about 400 hospitals in Europe which performed these
procedures in 1996.  Over 400,000 heart/lung bypass procedures were performed in
the United States in 1995, and approximately 265,000 heart/lung bypass
procedures were performed in Europe in 1994.  Coronary bypass surgeries
constitute a significant portion of the total number of heart/lung bypass
procedures performed each year.  Although the number of heart/lung bypass
procedures performed may have been less than the number of coronary bypass
surgeries due to multiple grafts being performed during some surgeries, the
number of graft procedures performed in the United States each year grew from
less than 200,000 in 1982 to over 400,000 in 1995. 
 
    The current annual worldwide market for disposable products and related
hardware and accessories for heart/lung bypass surgery is estimated by industry
analysts to be approximately $800 million, over $600 million of which is
estimated to be attributable to disposable products.  The two largest individual
markets for disposable products are the oxygenator market, estimated at
approximately $200 million in annual sales, and the custom tubing pack market,
estimated at approximately $100 million in annual sales. The Company's current
proprietary product offerings participate in an annual worldwide market for
disposable products estimated to be approximately $400 million, and the Company
anticipates that its proprietary products under development, including its new
blood pump, should allow the Company to pursue a greater portion of the
disposable product market.

    AFFINITY OXYGENATOR LINE.  The Company's AFFINITY oxygenator line is
currently comprised of the AFFINITY oxygenator, a hardshell cardiotomy venous
reservoir and a venous reservoir bag.  Upon receipt of appropriate regulatory
clearance, it is anticipated that the Company's new blood pump will also be
marketed as a part of the AFFINITY oxygenator line. 

    The AFFINITY oxygenator is a microporous, hollow fiber membrane oxygenator
which exchanges the carbon dioxide in the patient's blood for oxygen, returning
oxygenated blood to the patient through the heart/lung bypass circuit.  This
oxygenator incorporates the Company's patented radial flow and graduated density
fiber bundle, both of which were developed through the Company's use of
"computational fluid dynamics." Computational fluid dynamics helped the Company
design the AFFINITY oxygenator with features such as a lowered blood phase
pressure drop, a more uniform flow of blood through the device's fiber bundle,
and reduced damage to the blood as it passes through the device's blood phase. 
The key features of the AFFINITY oxygenator include the following:


                                          6

<PAGE>

- -   HIGH GAS TRANSFER.  The Company believes that the AFFINITY oxygenator
    offers superior gas transfer performance.  Studies conducted by independent
    investigators have demonstrated that the AFFINITY oxygenator has gas
    transfer performance equal or superior to that of most competing
    oxygenators.  The Company believes that most perfusionists desire
    oxygenators that provide optimum gas transfer performance to assure safety
    for patients requiring greater oxygen transfer capability, such as larger
    patients and patients operated on under lighter anesthesia or at warmer
    temperatures.
    
- -   LOW PRESSURE DROP.  Studies conducted by independent investigators have
    determined the pressure drop across the blood phase of the AFFINITY
    oxygenator to be as low or lower than that of other leading products.  The
    Company believes that perfusionists generally wish to avoid large pressure
    drops during heart/lung bypass procedures due to the risk of line failures
    associated with high pressure drop.
    
- -   LOW PRIMING VOLUME.  The AFFINITY oxygenator has a priming volume which the
    Company believes to be one of the lowest priming volumes among oxygenators
    currently available, and significantly less than the priming volume of
    three of the four largest selling competitive products.  Lower priming
    volume can result in less set-up time for the perfusionist, reduced
    dilution of the patient's blood with priming solutions and a reduced use of
    the patient's blood for priming, which lessens the possibility that costly
    and potentially dangerous donor blood products will need to be introduced
    during the procedure.
    
- -   EASE OF USE.  The AFFINITY oxygenator has been designed to be convenient to
    set up, prime and operate.  The AFFINITY'S relatively small size and
    universal adaptability contribute to its ease of handling, and its clear
    case helps to assure quick, complete priming and ongoing visual checks
    during the procedure.  The device's unique casing design and a proprietary
    manufacturing technique result in precise alignment of the uppermost blood
    port with the top of the fiber bundle, allowing for ease in venting air
    during the priming procedure.  The Company believes that perfusionists have
    a preference for oxygenators that permit easy removal of air during priming
    and ease of monitoring for the presence of air during the procedure. 

    Although competing oxygenators are generally designed to maximize one or
more of these key features, the Company believes the performance of the AFFINITY
oxygenator to be equal or superior to competing products across a broad range of
performance characteristics: gas transfer capability, pressure drop, priming
volume and ease of use. 

    In the heart/lung bypass circuit, the blood reservoir serves as a filtering
and storage device.  The AFFINITY product line offers two blood reservoirs, a
hardshell cardiotomy venous reservoir and a venous reservoir bag.  Computational
fluid dynamics modeling was also used in the development of these reservoirs. 
The hardshell reservoir can be used as a stand-alone unit or can be integrated
with the AFFINITY oxygenator in one unit.  The venous reservoir bag maintains
simplicity in its design while offering optimum priming ease, efficient air
handling and excellent mixing characteristics.  By offering these blood
reservoirs in the AFFINITY line, the Company is able to configure systems to
meet its customers' needs. 

    In July 1993, the Company began international marketing of the AFFINITY
oxygenator.  The Company began the commercial release of the AFFINITY oxygenator
in the U.S. market in February 1994, following marketing clearance from the FDA.
The Company received U.S. marketing clearance from the FDA for its AFFINITY
blood reservoirs in July 1994 and began marketing the devices following
clearance. 

    The Company is in the process of completing the development of a new blood
pump.  Upon receipt of regulatory clearance from the FDA, the Company intends to
market this device as the AFFINITY


                                          7

<PAGE>

Pump System.  By adding the AFFINITY Pump System to its product line, the
Company will be able to offer a complete line of proprietary devices comprising
the major components of the heart/lung bypass circuit.

    The AFFINITY Pump System incorporates a motor and control console, a rotor
housing, rotor assembly and a disposable pump chamber.  The Company believes
that the AFFINITY Pump System will offer a number of clinical safety advantages
over existing centrifugal or standard roller-type pumps.  In particular, the
modified roller-type design of the AFFINITY Pump System is designed to (i)
prevent significant negative pressure at the inlet, which minimizes the
potential for cavitation; (ii) not permit the draining of the venous reservoir
and the resulting introduction of air into the bypass circuit; (iii) not create
high discharge pressures sufficient to disrupt the tubing connections in the
bypass circuit; and (iv) not allow retrograde flow.  The Company believes that
the AFFINITY Pump System will be the first blood pump to combine these safety
features with performance comparable to available pumps.

    The marketing and sale of the AFFINITY Pump System is subject to receipt of
marketing clearance from the FDA pursuant to a 510(k) pre-market notification
filed by the Company in September 1996. While the Company believes that
marketing clearance for the AFFINITY Pump System could be received as early as
mid-1997, there can be no assurance that marketing clearance will be received
pursuant to the Company's 510(k), or on a timely basis, if at all. 
Additionally, there can be no assurance that the AFFINITY Pump System will be
perceived as superior to currently available blood pumps, that competitors will
not introduce future products with superior performance characteristics, or that
the AFFINITY Pump System will achieve market acceptance or generate material
revenues for the Company at any time in the near future, if at all.  See
"Important Factors" on page 19.
 
    SILICONE MEMBRANE OXYGENATOR LINE.  The Company's solid silicone membrane
oxygenator line consists of the Company's solid silicone membrane oxygenator and
associated cardiotomy reservoirs and the Company's ECMO (extracorporeal membrane
oxygenation) devices.  This product line was purchased by the Company from the
Predecessor Business. 

    The Company's solid silicone membrane oxygenators allow gases to pass to
and from blood using proprietary silicone membrane technology, as opposed to the
most widely used oxygenators that use microporous membrane technology (including
the AFFINITY oxygenator).  The solid silicone membrane technology permits, and
may be sold for, extended use applications because it does not experience the
performance deterioration over a longer period of use that occurs in a
microporous membrane oxygenator.  In addition, some perfusionists continue to
prefer silicone membrane oxygenators for heart/lung bypass procedures.  The
Company believes that its solid silicone membrane oxygenator is the only
oxygenator which is approved for sale for extended use of periods greater than
24 hours, providing the Company with a competitive advantage in this relatively
small market.  The Company markets a full line of solid silicone membrane
oxygenators in several models and sizes. 

    The Company's solid silicone membrane oxygenator is also part of the
Company's ECMO system.  ECMO is the long-term cardiopulmonary support of
premature infants, newborns and other patients with life-threatening respiratory
disorders.  The ECMO system includes the membrane oxygenator, reservoir bladder
bags and a heat exchanger. 

    SIGNATURE CUSTOM TUBING PACKS.  The Company's SIGNATURE custom tubing packs
include the tubing and other connections used to integrate the various
components of the heart/lung bypass circuit and ECMO system.  The components to
be included in each tubing pack and the manner in which they are arranged and
connected are determined by the specifications provided by the Company's
individual customers.  The Company has developed computer software that allows
it to design and fully document


                                          8

<PAGE>

custom tubing packs according to individual customer specifications and to quote
prices based on these specifications within hours of a customer request.  The
Company believes that this service provides it with a significant competitive
advantage.  While many of the devices included in the Company's SIGNATURE custom
tubing packs are manufactured by the Company, the Company currently does not
manufacture all the devices that may be requested by customers.  Consequently,
the Company is currently required to purchase certain components of its
SIGNATURE custom tubing packs from other medical device manufacturers.  The
Company received marketing clearance from the FDA for its SIGNATURE custom
tubing packs in June 1993.

    In October 1995, the Company received FDA clearance to market its AFFINITY
arterial filter which the Company generally sells as part of its SIGNATURE
Custom Tubing Packs.  The Company began sales of this product to customers in
late 1995, with full worldwide release in the first quarter of 1996.  The
AFFINITY arterial filter is the final component in the circuit of specialized
medical devices used in heart/lung bypass surgery, ensuring that the oxygenated
blood is free of air or particulate emboli before re-entering the patient's
body.  The Company believes that the AFFINITY arterial filter offers low volume
priming, high visibility and excellent air handling and hemodynamics.  The vast
majority of AFFINITY arterial filter devices are sold as components of custom
tubing packs.  Previously, the Company had sold filters from other manufacturers
as part of  its custom tubing packs.  

    MYOTHERM CARDIOPLEGIA DELIVERY SYSTEM.  The Company's MYOTHERM cardioplegia
delivery system is used to infuse specially formulated solutions, which often
include oxygenated blood, directly into the patient's coronary arteries while
the heart is stopped during heart/lung bypass surgery.  In addition to
delivering nutrients to the heart, these solutions are also used to arrest the
heart and maintain prescribed temperatures.  The Company believes that the
MYOTHERM cardioplegia delivery system provides superior levels of heat exchange
performance for optimum temperature control during both the cooling and warming
phases of heart/lung bypass surgery.  The MYOTHERM cardioplegia delivery system
also offers adaptability and convenience for varying cardioplegia techniques
used by cardiovascular surgeons.  The perfusionist is able to specify mixtures
of cardioplegia solutions and blood in the MYOTHERM cardioplegia delivery system
without changing the pump set-up.  Another feature of the MYOTHERM cardioplegia
delivery system is a self-venting drip chamber design, which affords the
perfusionist greater convenience and ease of priming. The MYOTHERM cardioplegia
delivery system is currently available in eight standard configurations and can
be configured on a customized basis to suit a surgeon's individual protocol. 
The Company released its MYOTHERM cardioplegia delivery system worldwide in
October 1991.  The Company is developing an improved MYOTHERM cardioplegia
delivery system scheduled for FDA submission late in the first quarter of 1997. 
See "Research and Development."

    ONCOURSE CONTINUOUS QUALITY CONTROL IMPROVEMENT SOFTWARE.  In addition to
the Company's medical device products, the Company introduced its ONCOURSE
continuous quality improvement (CQI) manager in December 1995.  This new
Microsoft Windows-based software program is currently offered free of charge to
customers who make a major commitment to the Company's products.  ONCOURSE CQI
Manager guides perfusionists through the necessary steps in establishing a CQI
program.  In addition, it generates a variety of useful reports for
perfusionists, including the annual American Board of Cardiovascular Perfusion
clinical activity report and several other specialized reports.  Although the
Company markets this product for sale to other customers, the Company does not
expect that this product will contribute significantly to its results of
operations in the foreseeable future.

RESEARCH AND DEVELOPMENT

    The Company's research and development strategy encompasses two approaches:
developing a more complete line of products for the heart/lung bypass circuit
and developing products which addresses new markets and opportunities outside of
the heart/lung bypass market and which leverage the Company's core technologies
and expertise. 

    As an integral part of both its research and development and sales and
marketing strategies, the Company strives to involve its customers to a large
extent in its product development activities.  Under confidentiality agreements,
the Company consults with selected customers from time to time as to market
needs and assessments of products under development by the Company.  The Company
believes that this practice allows it to receive end-user assessments of
products in development at an early stage and to better assure market
acceptance. 

    The Company's research and development staff currently consists of 24
full-time engineers, scientists, designers and technicians.  Research and
development expenses in 1996 were $3,651,000, as compared with $2,773,000 in
1995 and $2,309,000 in 1994.  The Company anticipates that 1997 research and
development costs will increase approximately 20% over 1995 levels, as the
Company moves to expand and improve its proprietary line of disposable medical
devices.  This forward-looking projection is dependent on the extent and timing
of new product development and the impact of the regulatory process in obtaining
marketing clearance for new products.  The need or desire to modify the
Company's existing products could also influence the level of research and
development expenses.  There can be no assurance, however, that the Company's
research and development efforts will result in any commercially successful
products. 

    As a result of the Company's research and development efforts, the Company
filed a 510(k) pre-market notification with the FDA in September 1996 covering
the AFFINITY Pump System.  Additionally, the Company submitted a 510(k) pre-
market notification late in the first quarter of 1997 covering an improved
MYOTHERM cardioplegia delivery system.  There can be no assurance that marketing
clearance for the AFFINITY Pump System or the improved MYOTHERM cardioplegia
delivery system will be received on a timely basis, if at all, or, if received,
that either device will become commercially successful.

MARKETING

    The Company markets its products in the United States and internationally,
with domestic sales accounting for 59%, 58% and 56% of consolidated net sales in
1996, 1995 and 1994 respectively. The majority of the Company's international
sales are in Europe. 

    To serve the U.S. market, the Company has developed a sales organization
that markets its products directly to cardiovascular surgeons, perfusionists,
neonatologists and ECMO specialists.  This organization consists of a staff of
17 direct sales employees, supplemented by seven independent sales
representative organizations and one distributor, all with cardiovascular sales
experience.  This network is managed by three regional sales managers and a vice
president of marketing and sales.  At its inception, the Company marketed its
products primarily through distributors and independent sales representatives. 
Since that time, the Company has shifted the composition of its distribution
network in the United States to include a larger direct sales component. 
Approximately 85% of the Company's U.S. sales in 1996 occurred through direct
sales employees and independent sales representatives.  The Company believes
that this shift to a larger direct sales force allows better control of the
sales process and assists the Company in developing closer relationships with
its customers. 


                                          10

<PAGE>

    Internationally, the Company sells its products through 38 cardiovascular
distributors who cover most major foreign markets.  The Company's U.K.
subsidiary, AVECOR Ltd., is the base of the Company's international marketing
efforts, and manufactures, assembles and distributes the Company's products to
the majority of the Company's international distribution network.  This
international distribution network is managed by an international sales director
and an export sales manager, both who are experienced in marketing heart/lung
bypass devices in Europe.  The Company's international distribution network is
supplemented by three direct sales employees, two in the U.K. and one in France.
 In October 1995, the Company opened a sales office in France, which is
organized as a subsidiary of AVECOR Ltd.  Total export sales to unaffiliated
entities (primarily to Europe and payable in U.S. dollars) and sales made by
AVECOR Ltd. were $4,912,000 and $13,111,000, respectively for the year ended
December 31, 1996; $3,480,000 and $10,702,000, respectively, for the year ended
December 31, 1995; and $3,365,000 and $6,184,000, respectively, for the year
ended December 31, 1994.

    The Company currently has written agreements with 28 of its domestic and
international independent sales representatives and distributors.  These
agreements generally impose geographic exclusivity and non-competition
obligations on the Company's independent sales representatives and distributors.
The Company's sales representative and distributorship agreements include a
provision that requires the Company to pay a commission to the sales
representative or distributor for any sales made directly by the Company to
customers within such sales representative's or distributor's territory.   The
Company may typically terminate these agreements upon breach of the agreement by
the distributor or sales representative, including breach of the quota or
minimum sales obligations imposed by the agreement, as well as certain
extraordinary events. 

    The Company's products are primarily sold to hospitals that perform
heart/lung bypass procedures. In the United States, the Company believes there
are approximately 1,000 hospitals at which heart/lung bypass procedures are
performed, while in Europe approximately 400 hospitals perform such procedures. 
There are approximately 112 hospitals worldwide where ECMO is performed.  The
Company's products are used by perfusionists, and the Company estimates that
there are about 3,000 perfusionists practicing in the United States. 

    A small portion of the Company's business is subject to longer term (longer
than one year) commitments with customers.  These commitments involve fixed
pricing terms and minimum or exclusive purchase obligations.  Many of the
Company's competitors, which have greater financial resources and broader and
longer-standing product lines than the Company, have experienced relatively
greater success in establishing these types of customer commitments.  The
Company anticipates that there will be increased use of these longer term, firm
commitment arrangements in its markets due to cost concerns and other factors.  

    The Company's sales and marketing strategy includes developing and
maintaining a close working relationship with its customers in order to assess
and satisfy their needs for products and services.  The Company meets with
certain designated customers several times each year, during which ideas are
shared regarding the marketplace in general, specific products, products under
development and existing or proposed programs.  In lieu of expensive advertising
and promotional materials, the Company maintains extensive contact with its
customers for the purpose of educating them in the Company's technologies and
manufacturing methods as well as to receive input and feedback about the
Company's product development and customer service functions.  The Company
believes these efforts to be cost-effective in producing awareness of, and
loyalty to, the Company's products.  


                                          11

<PAGE>

    The Company conducts frequent training of its sales force to facilitate
response to customer needs. The Company also maintains a 24-hour/day assistance
program in order to respond quickly to clinical questions and problems
encountered by its customers.  The assistance services are provided by a former
certified clinical perfusionist employed by the Company and are supplemented by
a certified clinical perfusionist employed by the Company as well as a network
of perfusionist consultants located across the country. 

    No single customer accounted for more than 10% of the Company's 1996 net
sales.

COMPETITION

    The cardiovascular device market in which the Company competes is
characterized by intense competition.  This market is dominated by established
manufacturers that have broader product lines, greater distribution
capabilities, substantially greater capital resources and larger marketing,
research and development staffs and facilities than the Company.  Many of these
competitors offer broader product lines within the specific heart/lung bypass
product market and/or in the general field of medical devices and supplies. 
Broader product lines give many of the Company's competitors the ability to
negotiate exclusive, long-term medical device supply contracts and,
consequently, the ability to offer comprehensive pricing of their competing
products.  By offering a broader product line in the general field of medical
devices and supplies, competitors may also have a significant advantage in
marketing competing products to group purchasing organizations, health
maintenance organizations and other managed-care organizations that increasingly
seek to reduce costs through centralization of purchasing functions.  In
addition, the Company's competitors have used price reductions to preserve
market share in the oxygenator and other product markets and there can be no
assurance that the Company's competitors will not use significant and prolonged
price competition across the Company's product lines in the future. 

    During the past two years, one of the Company's competitors, the Bentley
Division of Baxter Healthcare Corporation, purchased three companies which
provide contract perfusion services to hospitals. Although the Company believes
it is too early to assess the effect of these acquisitions on the Company's
business, the Company is likely to have increased difficulty selling its
heart/lung bypass products to perfusionists employed by the acquired companies
or to hospitals that contract with the acquired companies for perfusion
services. These acquisitions or other acquisitions by one or more of the
Company's competitors of other companies providing contract perfusion services
could have a material adverse effect on the Company's future business, financial
condition and results of operations.  

    The Company's primary competitors within the heart/lung bypass market
include COBE Cardiovascular Inc. (a subsidiary of Gambro, Inc.), Medtronic,
Inc., the Bentley Division of Baxter Healthcare Corporation, C.R. Bard Inc.,
Sorin Biomedical, Inc. (a subsidiary of Fiat), Terumo Medical Corporation and
SARNS Inc. (a subsidiary of 3M Company). 

    The Company believes that the principal competitive factors in the market
for heart/lung bypass and long-term respiratory support products are product
performance, quality, price, ease of use, technical innovation, cost-
effectiveness, field sales support, customer service and breadth of product
line.  The Company intends to continue to compete on the basis of its high
performance products, innovative technologies, cost-effective manufacturing
techniques, close customer relations and support and its strategy to increase
its offerings of products within the heart/lung bypass circuit and other medical
device technologies. 


                                          12

MANUFACTURING

    The Company manufactures oxygenators and other products and assembles
custom tubing packs at its U.S. facility located in Minneapolis, Minnesota.  The
Company also performs certain final manufacturing processes with respect to its
oxygenators and blood reservoirs and also assembles SIGNATURE custom tubing
packs at its Bellshill, Scotland facility. 

    The Company's U.K. and former U.S. manufacturing facilities have been
inspected by the British Standards Institute ("BSI") and, as a result, the
Company has received ISO 9001 certification.  BSI is also the "Notified Body"
that has verified that the Company's quality certification procedures conform
with the essential requirements necessary for the Company to prepare a
Declaration of Conformity and therefore place the "CE" mark on its products. 
See "Governmental Regulation." 

    As a part of the development process for new products, the Company
simultaneously designs and develops manufacturing processes and equipment to be
used to manufacture the products.  Because of the Company's ability to design
and produce its manufacturing equipment internally in conjunction with new
product development, the Company has been able to implement a highly automated,
cost-efficient manufacturing process for the products in its AFFINITY line.  

    The Company manufactures its oxygenators, blood reservoirs and ancillary
products from standard raw materials, components and custom manufactured
components presently purchased from outside suppliers.  The Company intends to
continue to purchase these raw materials, components and custom- manufactured
components from outside suppliers in the future.  While the Company believes
that the raw materials, components and custom manufactured components used in
the manufacture of its products are readily available from multiple sources,
certain of these items are purchased from single sources.  Although the Company
has qualified, or is in the process of investigating, alternate sources of
supply for key components and materials, any significant interruption in supply
of these items could have a material adverse effect on the Company's ability to
manufacture its products.  The Company has not experienced shortages or
significant delays in supply of these materials and components from its
suppliers. 

GOVERNMENTAL REGULATION

    The Company's products, development activities and manufacturing processes
are subject to regulation by numerous governmental authorities, principally the
FDA and corresponding foreign agencies. In the United States, the FDA
administers the Federal Food, Drug and Cosmetics Act and amendments thereto,
including the Safe Medical Devices Act of 1990.  The Company is subject to the
standards and procedures with respect to manufacture and marketing of medical
devices contained in the Federal Food, Drug and Cosmetics Act and the
regulations promulgated thereunder and is subject to inspection by the FDA for
compliance with such standards and procedures.  Noncompliance with applicable
requirements can result in, among other things, fines, injunctions, civil
penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant premarket clearance or premarket
approval for devices, withdrawal of marketing approvals and criminal
prosecution.

    In the United States, medical devices are classified into one of three
classes (class I, II or III), on the basis of the controls deemed necessary by
the FDA to reasonably assure their safety and effectiveness. Under FDA
regulations, class I devices are subject to general controls (E.G., labeling,
premarket notification and adherence to good manufacturing practices) and class
II devices are subject to general and special controls (E.G., performance
standards, postmarket surveillance, patient registries and FDA guidelines ).  In
general, class III devices (E.G., life-sustaining, life-supporting and
implantable devices, or new devices


                                          13

<PAGE>

which have not been found substantially equivalent to a legally marketed
device), in addition to being subject to general and special controls, must
receive premarket approval ("PMA") by the FDA to ensure their safety and
effectiveness.

    Before a new or significantly modified device can be introduced into the
market, the manufacturer must generally obtain marketing clearance through a
510(k) notification or approval of a PMA application. A 510(k) clearance will be
granted if the proposed device is "substantially equivalent" to a predicate
device (I.E., a legally marketed class I or class II medical device, or a class
III medical device for which the FDA has not called for the submission of a PMA
application).  Commercial distribution of a device for which a 510(k)
notification is required can begin only after the FDA issues a written
determination that the device is "substantially equivalent" to a predicate
device.  The FDA may determine that a proposed device is not substantially
equivalent to a predicate device, or that additional information or data are
needed before a substantial equivalence determination can be made.  A request
for additional data may require that clinical studies of the device's safety and
efficacy be performed. The process of obtaining a 510(k) clearance typically can
take several months to a year or longer.

    A PMA application must be filed if a proposed device is not substantially
equivalent to a legally marketed class I or class II device, or if it is a class
III device for which the FDA has called for a PMA application.  Certain class
III devices that were on the market before May 28, 1976 ("preamendments class
III devices"), and devices that are substantially equivalent to them, can be
brought to market through the 510(k) process until the FDA calls for the
submission of PMA applications for preamendments class III devices. The process
of obtaining a PMA can be expensive, uncertain and lengthy, frequently requiring
anywhere from one to several years from the date the PMA is submitted to the
FDA, if approval is obtained at all.  Moreover, a PMA application, if granted,
may include significant limitations on the indicated uses for which a product
may be marketed.  FDA enforcement policy strictly limits the marketing of
approved medical devices for unapproved or "off label" uses.  In addition,
product approvals can be withdrawn for failure to comply with regulatory
standards or the occurrence of unforeseen problems following initial marketing. 
All of the Company's current products have been the subject of successful 510(k)
submissions, and the Company believes that its products currently in development
will also be eligible for the 510(k) submission process, although there can be
no assurance that the FDA will agree with this view. 

    Certain of the Company's products are within product categories set forth
in an FDA order dated August 14, 1995, issued to all manufacturers of these
devices, which requires all of such manufacturers to submit additional data to
the FDA regarding the safety and the efficacy of the identified devices.  The
products affected include the Company's blood oxygenators, arterial filters and
defoamers, which, by current FDA interpretation, include both cardiotomy and
venous blood reservoirs.  Each of these devices is currently classified by the
FDA as a class III medical device which, because they were viewed as
substantially equivalent to preamendments class III devices, were cleared for
marketing through the 510(k) premarket notification process.  Through its August
14, 1995 order, the FDA has requested data from the Company and other
manufacturers of these devices in order to make a determination as to whether
these products should be reclassified as either class I or class II medical
devices.  If the FDA were to determine that such devices should remain
classified as class III medical devices, it would require manufacturers such as
the Company to submit PMA applications concerning such devices within 90 days
after the final FDA classification order.

    The Company is in the process of gathering the required data for submission
to the FDA, and is working with various industry groups and the FDA to seek
reclassification of these devices.  Although the FDA order requiring the
submission of data on blood oxygenators and arterial filters has characterized
these devices as having a high potential for down-classification, and the
Company believes that the devices will


                                          14

<PAGE>

be reclassified, there can be no assurance that these devices will be
reclassified.  Although the FDA order requesting data on defoamers has
characterized these devices as unlikely to be reclassified, and, therefore,
likely to require PMA submission, the Company is currently working to seek down-
classification.  The Company's efforts, in conjunction with those of other
manufacturers, are based on the belief that the types of blood reservoirs
currently used in heart/lung bypass circuits are significantly different from
the defoamers used with older, bubble-type oxygenators, and, based on safety and
efficacy data, should be reclassified.  While there can be no assurance that
these efforts will be successful, the Company believes that the likelihood of
reclassification of blood reservoirs is currently greater than indicated in the
FDA order.  In the event that any of the devices are not reclassified, the
Company may be required to submit a PMA application.  As discussed above, the
PMA application process can be expensive, uncertain and lengthy, and, if
required, could have a material adverse effect on the Company's future business,
financial condition or results of operations.

    The Company is also subject to regulation in each of the foreign countries
in which it sells its products with regard to product standards, packaging
requirements, labeling requirements, import restrictions, tariff regulations,
duties and tax requirements.  Many of the regulations applicable to the
Company's products in such countries are similar to those of the FDA.  The
national health or social security organizations of certain of such countries
require the Company's products to be qualified before they can be marketed in
those countries.  The Company relies on its independent distributors to comply
with the majority of the foreign regulatory requirements.  To date, the Company
has not experienced significant difficulty in complying with these regulations. 

    The Company is subject to periodic inspections by the FDA, which is charged
with auditing the Company's compliance with quality assurance systems
established by the FDA and other applicable government standards.  The Company
is also subject to inspections by the United Kingdom's Medical Devices
Directorate ("MDD") and other European regulatory agencies.  Strict regulatory
action may be initiated in response to audit deficiencies or to product
performance problems.  The Company believes that its manufacturing and quality
control procedures are in compliance with the requirements of the FDA and MDD
regulations.  The Company's manufacturing facilities and processes are also
subject to periodic inspection and review by BSI in conjunction with the
Company's ISO 9001 certification.  ISO certification is a series of standards
that define the basics of establishing, documenting and maintaining an effective
production quality management system.  The Company believes that ISO
certification creates value for the Company both internally, by providing an
objective criteria for measuring the Company's quality assurance efforts, and
externally, through customer recognition of, and demand for, products
manufactured by ISO certified manufacturers. 

    BSI is also the "Notified Body" that has verified that the Company's
quality certification procedures conform with the "essential requirements" set
forth by the MDD for the class of products produced by the Company.  Conformity
with these essential requirements enables the Company to prepare a Declaration
of Conformity which supports the placement of the "CE" mark on the Company's
products.  The CE mark enables the Company's products to be marketed, sold and
used throughout the European Union (the "EU"), subject to limited "safeguard"
powers of member states.  Presently, the CE mark is not required to be affixed
to the Company's products (or those of its competitors) sold in the EU, but may
be affixed during a transition period currently in effect and which began
January 1, 1995.  This transition period will end on January 1, 1999, when all
of the Company's products (and those of its competitors) will be required to
comply with the essential requirements in order to be marketed in the EU. 

    The financial arrangements through which the Company markets, sells and
distributes its products may be subject to certain federal and state laws as
well as regulations in the United States with respect to


                                          15

<PAGE>

the provision of services or products to patients who are Medicare or Medicaid
beneficiaries.  The "fraud and abuse" laws and regulations prohibit the knowing
and willful offer, payment or receipt of anything of value to induce the
referral of Medicare or Medicaid patients for services or goods.  In addition,
the physician anti-referral laws prohibit the referral of Medicare or Medicaid
patients for certain "Designated Health Services" to entities in which the
referring physician has an ownership or compensation interest.  Violations of
these laws and regulations may result in civil and criminal penalties, including
substantial fines and imprisonment.  In a number of states, the scope of fraud
and abuse or physician anti-referral laws and regulations, or both, have been
extended to include the provision of services or products to all patients,
regardless of the source of payment, although there is variation from state to
state as to the exact provisions of such laws or regulations.  In other states,
and, on a national level, several health care reform initiatives have been
proposed which would have a similar impact.  The Company believes that its
operations and its marketing, sales and distribution practices currently comply
in all respects with all current fraud and abuse and physician anti-referral
laws and regulations, to the extent they are applicable.  Although the Company
does not believe that it will need to undertake any significant expense or
modification to its operations or its marketing, sales and distribution
practices to comply with federal and state fraud and abuse and physician
anti-referral regulations currently in effect or proposed, financial
arrangements between manufacturers of medical devices and other health care
providers may be subject to increasing regulation in the future.  Compliance
with such regulation could adversely affect the Company's marketing, sales and
distribution practices, and may affect the Company in other respects not
presently foreseeable, but which could have a material adverse impact on the
Company's business, financial condition and results of operations.  

THIRD-PARTY REIMBURSEMENT AND COST CONTAINMENT

    The Company's products are purchased by hospitals and other users, which
then bill various third-party payors for the health care products and services
provided to the patients.  These payors, which include Medicare, Medicaid,
private insurance companies and managed care organizations, reimburse part or
all of the costs and fees associated with the procedures performed with these
devices. 

    Medicare and Medicaid reimbursement for hospitals is based on a fixed
amount for admitting a patient with a specific diagnosis.  Because of this fixed
reimbursement method, hospitals have incentives to use less costly methods in
treating Medicare and Medicaid patients, and will frequently make capital
expenditures to take advantage of less costly treatment technologies. 
Frequently, reimbursement is reduced to reflect the availability of a new
procedure or technique and, as a result, hospitals are generally willing to
implement new cost saving technologies before these downward adjustments take
effect.  Likewise, because the rate of reimbursement for certain physicians who
perform certain procedures has been, and may in the future be, reduced in the
event of further changes in the resource-based relative value scale method of
payment calculation, physicians may seek greater cost efficiency in treatment to
minimize any negative impact of reduced reimbursement.  Any amendments to
existing reimbursement rules and regulations which restrict or terminate the
reimbursement eligibility (or the extent or amount of coverage) of medical
procedures using the Company's products or the eligibility (or the extent or
amount of coverage) of the Company's products could have a material adverse
impact on the Company's business, financial condition and results of operations.

    In response to the focus of national attention on rising health care costs,
a number of changes to reduce costs have been proposed or have begun to emerge. 
There have been, and may continue to be, proposals by legislators and regulators
and third-party payors to curb these costs.  There has also been a significant
increase in the number of Americans enrolling in some form of managed care plan,
and over 80% of hospitals participate in or have agreements with HMOs.  It has
become a typical practice for hospitals to affiliate themselves with as many
managed care plans as possible.  Higher managed care


                                          16

<PAGE>

penetration typically drives down the prices of health care procedures, which in
turn places pressure on medical supply prices.  This causes hospitals to
implement tighter vendor selection and certification processes, by reducing the
number of vendors used, purchasing more products from fewer vendors and trading
discounts on price for guaranteed higher volumes to vendors.  Hospitals have
also sought to control and reduce costs over the last decade by joining group
purchasing organizations or purchasing alliances. The Company cannot predict
what continuing or future impact existing or proposed legislation, regulation or
such third-party payor measures may have on its future business, financial
condition or results of operations. 

    Because the primary application of the Company's products is in coronary
bypass procedures, changes in reimbursement policies and practices of third-
party payors with respect to coronary bypass surgery could have a substantial
and material adverse impact on sales of the Company's heart/lung bypass
products.  The development or increased use of more cost-effective treatments
for coronary artery disease could cause such payors to decrease or deny
reimbursement for coronary bypass surgery or to favor these other treatments. 

PATENTS AND PROPRIETARY RIGHTS

    The Company protects its technology by filing patent applications for the
patentable technologies that it considers important to the development of its
business.  The Company also relies upon trade secrets, know-how and continuing
technological innovations to develop and maintain its competitive position. 

    The Company currently holds six U.S. patents and has three pending U.S.
patent applications.  In addition, the Company has four pending foreign patent
applications.  Four of the Company's present U.S. patents cover significant
design features of the AFFINITY oxygenator, including the AFFINITY'S winding
mandrel, graduated density fiber bundle and heat exchanger water diverter.  The
Company's other issued U.S. Patents cover the designs of the AFFINITY venous
blood reservoirs.  The Company has pending U.S. Patent applications relating to
the design of the AFFINITY venous blood reservoir and the AFFINITY arterial
filter.  The Company's pending foreign patent applications consist of selected
overseas filings addressing the same intellectual property addressed by the
Company's issued and pending U.S. Patents.

    The three U.S. patents acquired by the Company from the Predecessor
Business cover the Company's solid silicone membrane oxygenator product line and
have expired.  The Company believes that the market for solid silicone membrane
oxygenators might not be large enough to justify the expenses associated with
market entry by a competitor, and therefore, the effect of the expiration of
these patents on the revenues of the Company will not be material. 

    The Company, like other firms that engage in the development and marketing
of medical technology products, must address issues and risks relating to
patents and trade secrets.  There can be no assurance that any of the Company's
pending or future U.S. or foreign patent applications will result in issued
patents, that any current or future U.S. or foreign patents of the Company will
not be challenged or circumvented by competitors or others, or that such patents
will be found to be valid or sufficiently broad to protect the Company's
technology or provide the Company with its desired competitive advantage.  The
validity and breadth of claims covered in medical technology patents involve
complex legal and factual questions and therefore may be highly uncertain.  The
Company may be required to institute litigation to enforce patents issued to the
Company or to determine the enforceability, scope and validity of the
proprietary rights of others. 


                                          17

<PAGE>

    The Company also relies on trade secrets and proprietary know-how which it
seeks to protect, in part, through confidentiality agreements with employees,
consultants and other parties.  There can be no assurance that these agreements
will not be breached, that the Company will have adequate remedies for any
breach, or that the Company's trade secrets will not otherwise become known to
or independently developed by competitors. 

    Claims by competitors and other third parties that the Company's products
allegedly infringe the patent rights of others could have a material adverse
effect on the Company.  The medical device industry is characterized by frequent
and substantial intellectual property litigation.  Intellectual property
litigation is complex and expensive, and the outcome of such litigation is
difficult to predict.  In March 1997, the Company filed a lawsuit seeking to
invalidate a newly issued U.S. patent held by Minntech Corporation ("Minntech"),
a competing manufacturer of blood oxygenators and other medical devices, and
requesting a determination that the Company's AFFINITY oxygenator does not
infringe the Minntech patent.  The Company filed the suit in response to a
December 1996 letter from Minntech, alleging that the AFFINITY oxygenator
infringes certain claims under Minntech's patent, and requesting discussion
regarding a possible license agreement.  The Company's action against Minntech
and any future litigation, regardless of outcome, could result in substantial
expense to the Company and significant diversion of the efforts of the Company's
technical and management personnel.  In addition, if Minntech were successfully
to bring an infringement counterclaim against the Company, or if the Company
were to be subject to an adverse determination in any other legal proceeding in
the future alleging patent infringement, the Company could become subject to an
injunction preventing the manufacture and sale of the infringing products and to
monetary damages, or might be forced to seek a license from the party alleging
patent infringement in order to continue to manufacture and sell any infringing
products, which it might not be able to obtain.  The outcome of any such legal
action, including the possibility of entering into such a license, could have a
material adverse effect on the Company's business, financial condition and
results of operations.  See "Legal Proceedings" on page 23.

    Pursuant to an Asset Purchase Agreement dated June 7, 1991 ("Asset Purchase
Agreement"), for approximately $1 million in cash and a $2.5 million note, the
Company acquired the business and assets, and assumed certain liabilities, of
the Predecessor Business.  In addition, under the terms of a Royalty Agreement
dated June 7, 1991 ("Royalty Agreement"), the Company is obligated to pay to
SCIMED Life Systems, Inc. ("SCIMED") specified royalties based on a percentage
of net sales (as defined) of products previously manufactured by the Predecessor
Business and future products developed from then-existing technology if the
Company achieves certain net sales thresholds with those products.  The Royalty
Agreement also provides for royalty payments on certain new generations of
developed products, if any, which use certain technology embodied in the
then-existing models of such products.  Royalties on net sales for individual
product lines range from 1% to 3%, only if aggregate net sales of such products
for the prior year calculated on the anniversary date (June 7) of the Royalty
Agreement exceed $10 million.  If aggregate net sales of such products exceed
$12 million, then additional royalties will be due on net sales in excess of $10
million at 150% of the stated royalty rates.  In June 1996, the Royalty
Agreement expired with respect to products previously manufactured by the
Predecessor Business and expires with respect to current products under
development at the time of the acquisition and certain new generation products
in June 2001.  The Company has charged $95,000 in 1996, $178,000 in 1995 and
$213,000 in 1994 to operations for royalties due under the Royalty Agreement for
sales of products previously manufactured by the Predecessor Business. The
Company believes that none of the products in the AFFINITY oxygenator line nor
any of the Company's products currently under development (including the
AFFINITY Pump System) will require royalty payments under the Royalty Agreement.


                                          18

<PAGE>

    In connection with the Asset Purchase Agreement, SCIMED also assigned to
the Company ten trademarks (one of which is registered) related to the Company's
current line of products previously manufactured by the Predecessor Business.  

EMPLOYEES

    As of March 9, 1997, the Company employed 325 persons full-time and 2
persons part-time, including 29 in research and development, 222 in
manufacturing, 42 in sales and marketing and 34 in general and administrative
functions.  The Company's employees are not represented by a union, and the
Company considers its relationship with its employees to be good. 

(d) FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
    SALES.

    Financial information about the Company's foreign and domestic operations
and export sales is contained in Note 7 to the Company's Consolidated Financial
Statements on page 18 of the Company's 1996 Annual Report and is incorporated
herein by reference.

ITEM 1A  IMPORTANT FACTORS.

The following factors are important and should be considered carefully in
connection with any evaluation of the Company's business, financial condition,
results of operations and prospects.  Additionally, the following factors could
cause the Company's actual results to differ materially from those reflected in
any forward-looking statements of the Company.

HIGHLY COMPETITIVE INDUSTRY

    The cardiovascular device market in which the Company competes is
characterized by intense competition.  This market is dominated by established
manufacturers that have broader product lines, greater distribution
capabilities, substantially greater capital resources and larger marketing,
research and development staffs and facilities than the Company.  Many of these
competitors offer broader product lines than the Company within the specific
heart/lung bypass product market and/or in the general field of medical devices
and supplies, giving these competitors advantages in marketing and pricing their
competing products.  In addition, the Company's competitors have used price
reductions to preserve market share in the oxygenator and other product markets
and there can be no assurance that the Company's competitors will not use
significant and prolonged price competition across the Company's product lines
in the future.  In order to compete effectively with these manufacturers, the
Company may in the future need to offer a more complete line of devices for the
heart/lung bypass circuit with superior product performance at a competitive
price.  Even if the Company is able to develop such a line of products, there
can be no assurance that the Company will be able to compete effectively. 
During the last two years, one of the Company's competitors, the Bentley
Division of Baxter Healthcare Corporation ("Baxter"), has purchased three
companies that provide contract perfusion services to hospitals. Although the
Company believes that it is too early to assess the long-term effect of these
acquisitions on the Company's business, the Company is likely to have increased
difficulty selling its heart/lung bypass products to perfusionists employed by
these providers of perfusion services or hospitals which contract with these
perfusion services providers.  These acquisitions, or other acquisitions by the
Company's competitors of other companies providing contract perfusion services,
could have a material adverse effect on the Company's future business, financial
condition and results of operations.


                                          19

DEPENDENCE ON MARKET ACCEPTANCE

    The Company's products are intended to replace products currently being
sold by its competitors.  The success of the Company will depend, among other
things, on the acceptance by the market of the Company's current products and
the products it develops and introduces in the future.  The Company intends to
develop cost-competitive products that provide clinical performance advantages
and convenience benefits to achieve more of a competitive advantage.  Product
development is expensive, and there can be no assurance that the Company will be
able to develop technologically superior products that can be manufactured at a
reasonable cost.  In addition, there is no assurance that the market will accept
the Company's product offerings as superior to those currently available or
that, if accepted as superior, the Company's product offerings will achieve
significant sales due to the broader product lines, greater distribution
capabilities, substantially greater capital resources and larger marketing
staffs of the Company's competitors.  There can be no assurance that the
Company's competitors will not succeed in developing or marketing products that
are viewed as providing superior clinical performance or are less expensive as
compared to the products currently marketed or to be developed by the Company.

PATENTS AND PROPRIETARY RIGHTS

    The Company protects its technology through patents and trade secrets. 
There can be no assurance that any pending or future patent applications will
result in issued patents or that any current or future patents will not be
challenged, invalidated or circumvented or that the rights granted thereunder
will provide any competitive advantage to the Company.  There can also be no
assurance that the Company's trade secrets or confidentiality agreements will
provide meaningful protection of the Company's proprietary information or, in
the event of a breach of any confidentiality agreement, that the Company will
have adequate remedies.  Furthermore, there can be no assurance that others will
not independently develop similar technologies or duplicate any technology
developed by the Company or that the Company's technology will not infringe
patents or other rights owned by others.

    Claims by competitors and other third parties that the Company's products
allegedly infringe the patent rights of others could have a material adverse
effect on the Company.  The medical device industry is characterized by frequent
and substantial intellectual property litigation.  Intellectual property
litigation is complex and expensive, and the outcome of such litigation is
difficult to predict.  In March 1997, the Company filed a lawsuit seeking to
invalidate a newly issued U.S. patent held by Minntech Corporation ("Minntech"),
a competing manufacturer of blood oxygenators and other medical devices, and
requesting a determination that the Company's AFFINITY oxygenator does not
infringe the Minntech patent.  The Company filed the suit in response to a
December 1996 letter from Minntech, alleging that the AFFINITY oxygenator
infringes certain claims under Minntech's patent, and requesting discussion
regarding a possible license agreement.  The Company's action against Minntech
and any future litigation, regardless of outcome, could result in substantial
expense to the Company and significant diversion of the efforts of the Company's
technical and management personnel.  In addition, if Minntech were successfully
to bring an infringement counterclaim against the Company, or if the Company
were to be subject to an adverse determination in any other legal proceeding in
the future alleging patent infringement, the Company could become subject to an
injunction preventing the manufacture and sale of the infringing products and to
monetary damages, or might be forced to seek a license from the party alleging
patent infringement in order to continue to manufacture and sell any infringing
products, which it might not be able to obtain.  The outcome of any such legal
action, including the possibility of entering into such a license, could have a
material adverse effect on the Company's business, financial condition and
results of operations.  See "Legal Proceedings" on page 23.

RISK OF TECHNOLOGICAL OBSOLESCENCE

    The markets for the Company's current and future products are highly
dependent on the number of surgical procedures performed each year requiring
heart/lung bypass.  The number of surgical procedures requiring heart/lung
bypass is dependent on a range of factors, including the incidence of coronary
artery disease, the effectiveness of alternative treatments for coronary artery
disease and the availability of third-party reimbursement for heart/lung bypass
procedures and other treatments.  In addition, new surgical and other
interventional procedures and/or drugs may be developed and become accepted in
the future which could reduce the importance of procedures that use the
Company's products. Accordingly, the Company's success will depend in large part
on the continued importance of surgical procedures that use the Company's
products and on the Company's ability to respond quickly to medical and
technological changes through the development and introduction of new, cost-
effective products.  There can be no assurance that the Company's existing
products or products in development will offer the same benefits at comparable
prices as competing products, or that the Company's competitors will not develop
new technologies that render the Company's products obsolete or not cost-
competitive.

ATTRACTION AND RETENTION OF KEY PERSONNEL

    The Company is dependent in large part upon its ability to attract and
retain qualified scientific, technical and key management personnel due to the
specialized scientific nature of the Company's business.  There is intense
competition for qualified personnel in the Company's industry and there can be
no assurance that the Company will be able to continue to attract and retain
qualified personnel for the development of its business.

INTERRUPTION IN SOURCES OF SUPPLY

    The Company currently purchases, and will continue to purchase, raw
materials and components for its products from outside vendors.  Certain of the
components used in the Company's products are purchased from single sources. 
Although the Company has qualified, or is in the process of investigating,
alternate sources of supply for key components, any significant interruption in
supply could have a material adverse effect on the Company's future business,
financial condition and results of operations.

DEPENDENCE ON DISTRIBUTOR SALES

    Sales to distributors constitute a significant portion of the Company's
business both in the U.S. and  foreign markets.  Although no single customer
accounted for more than 10% of the Company's net sales in 1996, one foreign
distributor accounted for approximately 10% of the Company's net sales in 1995
and a different foreign distributor accounted for approximately 11% of the
Company's net sales in 1994.  In addition, the Company has further developed its
direct sales organization to service the majority of its domestic market, one
U.S. distributor accounted for approximately 11% of the Company's net sales in
1995. There can be no assurance that the Company will be able to maintain its
relationships with significant distributors, or, in the event of termination of
such relationships, that new distributors will be found.  The loss of a
significant distributor could materially adversely affect the Company's future
business, financial condition and results of operations if a new distributor or
other suitable sales organization could not be found on a timely basis in the
relevant geographic market.


                                          21

<PAGE>

GOVERNMENTAL REGULATION

    The Company's products, development activities and manufacturing processes
are subject to extensive and rigorous regulation by the FDA and by comparable
agencies in foreign countries.  In the United States, the FDA regulates the
introduction of medical devices as well as manufacturing, labeling and
recordkeeping procedures for such products.  The process of obtaining marketing
clearance from the FDA for new products can be time consuming and expensive, and
there is no assurance that such clearances will be granted or that FDA review
will not involve delays that would adversely affect the Company's ability to
commercialize additional products.  Even if regulatory approvals to market a
product are obtained from the FDA, these approvals may entail limitations on the
indicated uses of the product.  Marketing clearances by the FDA can also be
withdrawn due to failure to comply with regulatory standards or the occurrence
of unforeseen problems following initial approval.  The FDA could also limit or
prevent the manufacture or distribution of the Company's products and has the
power to require the recall of such products.  The FDA, various state agencies
and foreign regulatory agencies inspect the Company and its facilities from time
to time to determine whether the Company is in compliance with various
regulations relating to manufacturing practices, validation, testing, quality
control and product labeling.  A determination that the Company is in violation
of such regulations could lead to imposition of civil penalties, including
fines, product recalls or product seizures and, in extreme cases, criminal
sanctions. 

    A significant portion of the Company's revenues are dependent upon sales of
its products outside the United States through independent distributors. 
International regulatory bodies have established varying regulations governing
product standards, packaging requirements, labeling requirements, import
restrictions, tariff regulations, duties and tax requirements.  The Company
relies upon independent distributors to comply with the majority of the foreign
regulatory requirements.  The inability or failure of independent distributors
to comply with the varying regulations or the imposition of new regulations
could restrict such distributors' ability to sell the Company's products
internationally and thereby adversely effect the Company's future business,
financial condition and results of operations. 

LIMITATIONS ON THIRD-PARTY REIMBURSEMENT

    The Company's products are purchased by hospitals and other users, which
bill various third-party payors, such as government health programs, private
health insurance plans, managed care organizations and other similar programs,
for the health care goods and services provided to their patients.  Third-party
payors are increasingly challenging the prices charged for medical products and
services and, in some instances, have put pressure on medical suppliers to lower
their prices.  The Company is unable to predict what changes will be made in the
reimbursement methods used by third-party health care payors.  There can be no
assurance that the treatment of coronary artery disease using coronary artery
bypass graft surgery will be considered cost-effective by third-party payors,
that reimbursement for such surgery will be available or, if available, that
payors' reimbursement levels will not adversely affect the Company's ability to
sell its products on a profitable basis.  In addition, the cost of health care
has risen significantly over the past decade, and there have been, and may
continue to be, proposals by legislators and regulators to curb these costs. 
Legislative action limiting reimbursement for certain procedures could have a
material adverse effect on the Company's future business, financial condition
and results of operations.


                                          22

<PAGE>

EXPOSURE TO PRODUCT LIABILITY CLAIMS; RISK OF PRODUCT RECALL

    The medical device industry historically has been litigious, and the
manufacture and sale of the Company's products inherently entails a risk of
product liability claims.  Although the Company maintains product liability
insurance in amounts believed to be adequate based upon the nature and risks of
its business in general and its actual experience to date, there can be no
assurance that one or more liability claims will not exceed the coverage limits
of such policies or that such insurance will continue to be available on
commercially reasonable terms, if at all.  Further, the Company does not expect
to be able to obtain insurance covering its costs and losses as the result of
any recall of its products due to alleged defects, whether or not such a recall
is instituted by the Company or required by a regulatory agency. While the
Company has not experienced any product liability claims or recalls to date, a
product liability claim, recall or other claim with respect to uninsured
liabilities or in excess of insured limits could have a material adverse effect
on the future business, financial condition and results of operations of the
Company.

ITEM 2.  PROPERTIES.
         
    The Company's principal executive offices, research and development
facilities and U.S. manufacturing facilities are located at 7611 Northland
Drive, Minneapolis, Minnesota, consisting of approximately 100,000 square feet.

    The Company's United Kingdom manufacturing facility is located at Phoenix
Crescent, Strathclyde Business Park, Bellshill, Scotland, U.K. ML43NJ,
consisting of approximately 15,000 square feet.  The Company leases such space
through its AVECOR Ltd. subsidiary pursuant to a lease expiring in 2003.  The
lease provides for monthly rent of approximately $10,000 (based on current
exchange rates) until 1998 when the monthly rent is subject to adjustment based
upon current Scotland rental market rates.  The Company also pays a pro rata
share of operating expenses and real estate taxes.

    In July 1996, the Minnesota Pollution Control Agency granted the Company a
five-year air emission facility permit for the Company's manufacturing
operations at its facility located at 7611 Northland Drive, Minneapolis,
Minnesota 55428.  The Company believes that it has been in compliance with this
permit since its issuance and that it is in compliance in all material aspects
with federal and state laws relating to environmental matters.  However,
expected future changes in federal or state regulations relating to air
emissions could require the Company to install air emission control equipment or
modify its manufacturing operations, which the Company believes would not have a
material adverse effect on its business. 

ITEM 3.  LEGAL PROCEEDINGS.

    In March 1997, the Company filed suit in U.S. District Court for the
District of Minnesota, seeking to invalidate a newly issued U.S. patent held by
Minntech Corporation ("Minntech"), a competing manufacturer of blood oxygenators
and other medical devices, and requesting a determination that the Company's
AFFINITY oxygenator does not infringe the Minntech patent.  The Company filed
the suit in response to a December 1996 letter from Minntech, alleging that the
AFFINITY oxygenator infringes certain claims under Minntech's patent, and
requesting discussion regarding a possible license agreement.  The Company
reviewed the subject patent and concluded, based on an opinion from its patent
counsel, that none of the claims in the patent are infringed by the AFFINITY
oxygenator, and that the patent is, in any event, invalid.  However, the expense
and effort potentially required to bring this action, as well as the outcome of
any counterclaim successfully brought against the Company by Minntech,


                                          23

condition and results of operations.  See "Important Factors - Patents and
Proprietary Rights" on page 20.

                                 PLAN ADMINISTRATION

 3.2.    AUTHORITY OF THE COMMITTEE.

         (a)  In accordance with and subject to the provisions of the Plan, the
              Committee shall have the authority to determine the following:
              (i) the Eligible Recipients who shall be selected as
              Participants, (ii) the nature and extent of the Incentive Awards
              to be made to each Participant (including the number of shares of
              Common Stock to be subject to each Incentive Award, any exercise
              price and the manner in which Incentive Awards will vest or
              become exercisable), (iii) the time or times when Incentive
              Awards will be granted, (iv) the duration of each Incentive
              Award, (v) the restrictions and other conditions to which the
              payment or vesting of Incentive Awards may be subject, and (vi)
              such other provisions of the Incentive Awards as the Committee
              may deem necessary or desirable and as consistent with the terms
              of the Plan.  The Committee shall determine the form or forms of
              the agreements with Participants which shall evidence the
              particular terms, conditions, rights and duties of the Company
              and the Participants with respect to Incentive Awards granted
              pursuant to the Plan, which agreements shall be consistent with
              the provisions of the Plan.

         (b)  With the consent of the Participant affected thereby, the
              Committee may amend or modify the terms of any outstanding
              Incentive Award in any manner, provided that the amended or
              modified terms are permitted by the Plan as then in effect.
              Without limiting the generality of the foregoing sentence, the
              Committee may, with the consent of the Participant affected
              thereby, modify the exercise price, number of shares or other
              terms and conditions of an Incentive Award, extend the term of an
              Incentive Award, accelerate the exerciseability or vesting or
              otherwise terminate any restrictions relating to an Incentive
              Award, accept the surrender of any outstanding Incentive Award,
              or, to the extent not previously exercised or vested, authorize
              the grant of new Incentive Awards in substitution for surrendered
              Incentive Awards.

         (c)  With respect to the Company or any other entity whose performance
              is relevant to the grant or vesting of an Incentive Award, in the
              event of (i) any reorganization, merger, consolidation,
              recapitalization, liquidation, reclassification, stock dividend,
              stock split, combination of shares, rights offering or
              divestiture (including a spin-off) or any other change in
              corporate structure or shares, (ii) any purchase, acquisition,
              sale or disposition of a significant amount of assets or a
              significant business, any extraordinary dividend or any other
              similar transaction, (iii) any change in accounting principles or
              practices, or (iv) any other significant change in financial
              condition, the Committee (or, if the Company is not the surviving
              corporation in any such transaction, the board of directors of
              the surviving corporation) may, without the consent of the
              Participant affected thereby, amend or modify the vesting
              criteria of any outstanding Incentive Award that is based in
              whole or in part on the financial performance of the Company or
              such other entity so as equitably to reflect such event, with
              desired result that the criteria for evaluating such financial
              performance of the Company or such other entity shall be
              substantially the same (in the sole discretion of the Committee
              or the board of directors of the surviving corporation) following
              such event as prior to such event; provided, however, that the
              amended or modified terms are permitted by the Plan as then in
              effect.

         (d)  The Committee shall have the authority, subject to the provisions
              of the Plan, to establish, adopt and revise such rules and
              regulations relating to the Plan as it may deem necessary or
              advisable for the administration of the Plan.  The Committee's
              decisions

              and determinations under the Plan need not be uniform and may be
              made selectively among Participants, whether or not such
              Participants are similarly situated.  Each determination,
              interpretation or other action made or taken by the Committee
              pursuant to the provisions of the Plan shall be conclusive and
              binding for all purposes and on all persons, including, without
              limitation, the Company and its Subsidiaries, the shareholders of
              the Company, the Committee and each of its members, the
              directors, officers and employees of the Company and its
              Subsidiaries, and the Participants and their respective
              successors in interest.  No member of the Committee shall be
              liable for any action or determination made in good faith with
              respect to the Plan or any Incentive Award granted under the
              Plan.

                              STOCK SUBJECT TO THE PLAN

 4.1.    NUMBER OF SHARES.  Subject to adjustment as provided in Section 4.3 of
         the Plan, the maximum number of shares of Common Stock that shall be
         reserved for issuance under the Plan shall be 1,050,000 shares of
         Common Stock.  The maximum number of shares authorized and reserved
         may be increased from time to time by approval of the Board and, if
         required pursuant to Rule 16b-3 under the Exchange Act, Section 422 of
         the Code, or the rules of any securities exchange or the NASD, the
         shareholders of the Company.

 4.2.    SHARES AVAILABLE FOR USE.  Shares of Common Stock that may be issued
         upon exercise of Options or that are issued as Restricted Stock Awards
         shall be applied to reduce the maximum number of shares of Common
         Stock remaining available for use under the Plan.  Any shares of
         Common Stock that are subject to an Option (or any portion thereof)
         that lapses, expires or for any reason is terminated unexercised shall
         automatically again become available for use under the Plan.  Any
         shares of Common Stock that constitute the forfeited portion of a
         Restricted Stock Award, however, shall not become available for
         further use under the Plan.

 4.3.    ADJUSTMENTS TO SHARES.  In the event of any reorganization, merger,
         consolidation, recapitalization, liquidation, reclassification, stock
         dividend, stock split, combination of shares, rights offering,
         extraordinary dividend (including a spin-off) or any other change in
         the corporate structure or shares of the Company, the Committee (or,
         if the Company is not the surviving corporation in any such
         transaction, the board of directors of the surviving corporation)
         shall make appropriate adjustment (which determination shall be
         conclusive) as to the number and kind of securities subject to and
         reserved under the Plan and, in order to prevent dilution or
         enlargement of the rights of Participants, the number, kind and, where
         applicable, exercise price of securities subject to outstanding
         Incentive Awards.  Without limiting the generality of the foregoing,
         in the event that any of such transactions are effected in such a way
         that the holder of Common Stock shall be entitled to receive stock,
         securities or assets, including cash, with respect to or in exchange
         for such Common Stock, all Participants holding outstanding Options
         shall upon the exercise of such Options receive, in lieu of any shares
         of Common Stock that they may be entitled to receive, such stock,
         securities or assets, including cash, as would have been issued to
         such Participants if their Options had been exercised and such
         Participants had received Common Stock prior to such transaction.

                                    PARTICIPATION

    Participants in the Plan shall be those Eligible Recipients who, in the
judgment of the Committee, have performed, are performing, or during the term of
an Incentive Award will perform, services in the management, operation and
development of the Company or any Subsidiary, and significantly contributed, are
significantly contributing or are expected to significantly contribute to the
achievement of corporate economic objectives.  Eligible Recipients may be
granted from time to time one or more Incentive Awards, as may be determined by
the Committee in its sole discretion.  The number, type, terms and conditions of
Incentive Awards granted to various Eligible Recipients need not be uniform,
consistent or in accordance with any plan, regardless of whether such Eligible
Recipients are similarly situated.  Upon determination by the Committee that an
Incentive Award is to be granted to an Eligible Recipient, written notice shall
be given such person, specifying the terms, conditions, rights and duties
related thereto.  Each Eligible Recipient to whom an Incentive Award is to be
granted shall enter into an agreement with the Company, in such form as the
Committee shall determine and which is consistent with the provisions of the
Plan, specifying such terms, conditions, rights and duties.  Incentive Awards
shall be deemed to be granted as of the date specified in the grant resolution
of the Committee, which date shall be the date of the related agreement with the
Participant.

                                    STOCK OPTIONS

 6.1.    GRANT.  An Eligible Recipient may be granted one or more Options under
         the Plan, and such Options shall be subject to such terms and
         conditions, consistent with the other provisions of the Plan, as shall
         be determined by the Committee in its sole discretion.  The Committee
         may designate whether an Option is to be considered an Incentive Stock
         Option or a Non-Statutory Stock Option; provided, however, that an
         Incentive Stock Option shall be granted only to an Eligible Recipient
         who is an employee of the Company or a Subsidiary.  The terms of the
         agreement relating to a Non-Statutory Stock Option shall expressly
         provide that such Option shall not be treated as an Incentive Stock
         Option.

 6.2.    EXERCISE.  An Option shall become exercisable at such times and in
         such installments (which may be cumulative) as shall be determined by
         the Committee in its sole discretion at the time the Option is
         granted.  Upon the completion of its exercise period, an Option, to
         the extent not then exercised, shall expire.

 6.3.    EXERCISE PRICE.

         (a)  INCENTIVE STOCK OPTIONS.  The per share price to be paid by the
              Participant at the time an Incentive Stock Option is exercised
              shall be determined by the Committee, in its discretion, at the
              date of its grant; provided, however, that such price shall not
              be less than (i) 100% of the Fair Market Value of one share of
              Common Stock on the date the Option is granted, or (ii) 110% of
              the Fair Market Value of one share of Common Stock on the date
              the Option is granted if, at the time the Option is granted, the
              Participant owns, directly or indirectly (as determined pursuant
              to Section 424(d) of the Code), more than 10% of the total
              combined voting power of all classes of stock of the Company, any

              subsidiary corporation or any parent corporation of the Company
              (within the meaning of Sections 424(f) and 424(e), respectively,
              of the Code).

         (b)  NON-STATUTORY STOCK OPTIONS.  The per share price to be paid by
              the Participant at the time a Non-Statutory Stock Option is
              exercised shall be determined by the Committee in its sole
              discretion at the time the Option is granted, but shall not be
              less than 85% of the Fair Market Value of one share of Common
              Stock on the date the Option is granted.

 6.4.    DURATION.

         (a)  INCENTIVE STOCK OPTIONS.  The period during which an Incentive
              Stock Option may be exercised shall be fixed by the Committee in
              its sole discretion at the time such Option is granted; provided,
              however, that in no event shall such period exceed 10 years from
              its date of grant or, in the case of a Participant who owns,
              directly or indirectly (as determined pursuant to Section 424(d)
              of the Code), more than 10% of the total combined voting power of
              all classes of stock of the Company, any subsidiary corporation
              or any parent corporation of the Company (within the meaning of
              Sections 424(f) and 424(e), respectively, of the Code), five
              years from its date of grant.

         (b)  NON-STATUTORY STOCK OPTION.  The period during which a
              Non-Statutory Stock Option may be exercised shall be fixed by the
              Committee in its sole discretion at its date of grant.

         (c)  EFFECT OF TERMINATION OF EMPLOYMENT.  Notwithstanding the
              foregoing, except as provided in Articles 10 and 12 of the Plan,
              all Options granted to a Participant shall terminate and may no
              longer be exercised if the Participant's employment with the
              Company and all Subsidiaries ceases.

 6.5.    MANNER OF OPTION EXERCISE.  An Option may be exercised by a
         Participant in whole or in part from time to time, subject to the
         conditions contained herein and in the agreement evidencing such
         Option, by delivery, in person or through certified or registered
         mail, of written notice of exercise to the Company at its principal
         executive office in Minneapolis, Minnesota (Attention: Treasurer), and
         by paying in full the total Option exercise price for the shares of
         Common Stock purchased.  Such notice shall be in a form satisfactory
         to the Committee and shall specify the particular Option (or portion
         thereof) that is being exercised and the number of shares with respect
         to which the Option is being exercised.  Subject to compliance with
         Section 14.1 of the Plan, the exercise of the Option shall be deemed
         effective upon receipt of such notice and payment complying with the
         terms of the Plan and the agreement evidencing such Option.  As soon
         as practicable after the effective exercise of the Option, the
         Participant shall be recorded on the stock transfer books of the
         Company as the owner of the shares purchased, and the Company shall
         deliver to the Participant one or more duly issued stock certificates
         evidencing such ownership.  If a Participant exercises any Option with
         respect to some, but not all, of the shares of Common Stock subject to
         such Option, the right to exercise such Option with respect to the
         remaining shares shall continue until it expires or terminates in
         accordance with its terms.  An Option shall only be exercisable with
         respect to whole shares.

 6.6.    PAYMENT OF EXERCISE PRICE.

         (a)  The total purchase price of the shares to be purchased upon
              exercise of an Option shall be paid entirely in cash (including
              check, bank draft or money order); provided, however, that the
              Committee, in its sole discretion, may allow such payments to be
              made, in whole or in part, by delivery of a Broker Exercise
              Notice or a promissory note (containing such terms and conditions
              as the Committee may in its discretion determine), by transfer
              from the Participant to the Company of Previously Acquired
              Shares, or by a combination thereof.  In determining whether or
              upon what terms and conditions a Participant will be permitted to
              pay the purchase price of an Option in a form other than cash,
              the Committee may consider all relevant facts and circumstances,
              including, without limitation, the tax and securities law
              consequences to the Participant and the Company and the financial
              accounting consequences to the Company.  In the event the
              Participant is permitted to pay the total purchase price of an
              Option in whole or in part with Previously Acquired Shares, the
              value of such shares shall be equal to their Fair Market Value on
              the date of exercise of the Option.

         (b)  For purposes of this Section 6.6, a "Broker Exercise Notice"
              shall mean a written notice from a Participant to the Company at
              its principal executive office in Minneapolis, Minnesota
              (Attention: Treasurer), made on a form and in the manner as the
              Committee may from time to time determine, pursuant to which the
              Participant irrevocably elects to exercise all or any portion of
              an Option and irrevocably directs the Company to deliver the
              Participant's stock certificates to be issued to such Participant
              upon such Option exercise directly to a broker or dealer.  A
              Broker Exercise Notice must be accompanied by or contain
              irrevocable instructions to the broker or dealer (i) to promptly
              sell a sufficient number of shares of such Common Stock or to
              loan the Participant a sufficient amount of money to pay the
              exercise price for the Options and, if not otherwise satisfied by
              the Participant, to fund any related employment and withholding
              tax obligations due upon such exercise, and (ii) to promptly
              remit such sums to the Company upon the broker's or dealer's
              receipt of the stock certificates.

 6.7.    RIGHTS AS A SHAREHOLDER.  The Participant shall have no rights as a
         shareholder with respect to any shares of Common Stock covered by an
         Option until the Participant shall have become the holder of record of
         such shares, and no adjustments shall be made for dividends or other
         distributions or other rights as to which there is a record date
         preceding the date the Participant becomes the holder of record of
         such shares, except as the Committee may determine pursuant to Section
         4.3 of the Plan.

 6.8.    DISPOSITION OF COMMON STOCK ACQUIRED PURSUANT TO THE EXERCISE OF
         INCENTIVE STOCK OPTIONS.  Prior to making a disposition (as defined in
         Section 424(c) of the Code) of any shares of Common Stock acquired
         pursuant to the exercise of an Incentive Stock Option granted under
         the Plan before the expiration of two years after its date of grant or
         before the expiration of one year after its date of exercise and the
         date on which such shares of Common Stock were transferred to the
         Participant pursuant to exercise of the Option, the Participant shall
         send written notice to the Company of the proposed date of such
         disposition, the number of shares to be disposed of, the amount of
         proceeds to be received from such disposition and any other
         information relating to such disposition that the Company may
         reasonably request.  The right of a Participant to make any such
         disposition shall be conditioned on the receipt by the Company of all
         amounts necessary to satisfy any federal, state or local withholding
         and employment-related tax


                                          8


<PAGE>

         requirements attributable to such disposition.  The Committee shall
         have the right, in its sole discretion, to endorse the certificates
         representing such shares with a legend restricting transfer and to
         cause a stop transfer order to be entered with the Company's transfer
         agent until such time as the Company receives the amounts necessary to
         satisfy such withholding and employment-related tax requirements or
         until the later of the expiration of two years from its date of grant
         or one year from its date of exercise and the date on which such
         shares were transferred to the Participant pursuant to the exercise of
         the Option.

 6.9.    AGGREGATE LIMITATION OF STOCK SUBJECT TO INCENTIVE STOCK OPTIONS.  To
         the extent that the aggregate Fair Market Value (determined as of the
         date an Incentive Stock Option is granted) of the shares of Common
         Stock with respect to which incentive stock options (within the
         meaning of Section 422 of the Code) are exercisable for the first time
         by a Participant during any calendar year (under the Plan and any
         other incentive stock option plans of the Company, any subsidiary or
         any parent corporation of the Company (within the meaning of Sections
         424(f) and 424(e), respectively, of the Code)) exceeds $100,000 (or
         such other amount as may be prescribed by the Code from time to time),
         such excess Options shall be treated as Non-Statutory Stock Options.
         The determination shall be made by taking incentive stock options into
         account in the order in which they were granted.  If such excess only
         applies to a portion of an incentive stock option, the Committee, in
         its discretion, shall designate which shares shall be treated as
         shares to be acquired upon exercise of an incentive stock option.

                               RESTRICTED STOCK AWARDS

 7.1.    GRANT.  An Eligible Recipient may be granted one or more Restricted
         Stock Awards under the Plan, and such Restricted Stock Awards shall be
         subject to such terms and conditions, consistent with the other
         provisions of the Plan, as shall be determined by the Committee in its
         sole discretion.

 7.2.    VESTING.  A Restricted Stock Award shall vest at such times and in
         such installments, if any, as shall be determined by the Committee in
         its sole discretion at the time the Restricted Stock Award is granted.
         The Committee may impose such restrictions or conditions, not
         inconsistent with the provisions of the Plan, to the vesting of such
         Restricted Stock Awards as it deems appropriate, including, without
         limitation, that the Participant remain in the continuous employ or
         service of the Company or a Subsidiary for a certain period, or that
         the Participant or the Company (or any subsidiary or division thereof)
         achieve certain performance criteria.  The Committee may, in its sole
         discretion, require different restrictions with respect to different
         Participants, with respect to different Restricted Stock Awards or
         with respect to separate, designated portions of a Restricted Stock
         Award.  Except as otherwise provided in Articles 10 and 12 of the
         Plan, if a Participant's employment or other service with the Company
         and all Subsidiaries terminates prior to the vesting of any Restricted
         Stock Award, any portion of such Restricted Stock Award which has not
         yet vested shall be forfeited, and all shares of Common Stock (and any
         dividends and distributions as described in Section 7.4 of the Plan)
         related thereto shall be immediately returned to the Company.

 7.3.    RIGHTS AS A SHAREHOLDER; TRANSFERABILITY.  A Participant shall have
         all voting, dividend, liquidation and other rights with respect to
         shares of Common Stock issued to the Participant as a Restricted Stock
         Award under this Article 7 upon the Participant becoming the holder of
         record


                                          9


<PAGE>

         of such Restricted Stock Award as if such Participant were a holder of
         record of unrestricted Common Stock; provided, however, that prior to
         the vesting of any Restricted Stock Award, the Participant's right to
         assign or transfer such shares of Common Stock issued as a Restricted
         Stock Award shall be subject to the limitations of Section 13.2 of the
         Plan.  As soon as practicable after the vesting of any Restricted
         Stock Award, the Company shall cause to be delivered to the
         Participant a certificate evidencing such shares of Common Stock
         together with any dividends and distributions related thereto.

 7.4.    DIVIDENDS AND DISTRIBUTIONS.  Unless the Committee determines
         otherwise in its sole discretion, any dividends or distributions
         (including dividends or distributions paid in cash) paid with respect
         to shares of Common Stock subject to a Restricted Stock Award for
         which the restrictions have not yet ended shall be subject to the same
         restrictions as the shares to which such dividends or distributions
         relate and shall be promptly deposited with the custodian designated
         pursuant to Section 7.5 of the Plan.  The Committee shall determine in
         its sole discretion whether any interest shall be paid on such
         dividends or distributions.

 7.5.    ENFORCEMENT OF RESTRICTIONS.  The Committee may, in its sole
         discretion, require one or more of the following methods of enforcing
         the restrictions referred to in Sections 7.2 and 7.3 of the Plan:
         (a) placing a legend on the stock certificates referring to the
         restrictions; (b) requiring the Participant to keep the stock
         certificates, duly endorsed, in the custody of the Company while the
         restrictions remain in effect; or (c) requiring that the stock
         certificates, duly endorsed, be held in the custody of a third party
         while the restrictions remain in effect.

 7.5.    LIEN ON SHARES.  The Committee may, in its sole discretion, require
         that a Participant, as a condition to the grant of a Restricted Stock
         Award, grant to the Company a possessory lien on the shares of Common
         Stock subject to the Restricted Stock Award and any dividends or
         distributions related thereto in order to (a) secure retransfer of
         shares of Common Stock subject to a Restricted Stock Award into the
         name of the Company, and (b) ensure adequate provision for any tax
         withholding obligations arising out of the receipt of, or the lapse or
         termination of the restrictions or the payment of any dividends or
         other distributions with respect to, a Restricted Stock Award.

consistent with the other provisions of the Plan, as shall be determined by the
Committee in its sole discretion, including, without limitation, that the
Company (or any subsidiary or division thereof) achieve certain performance
criteria.  The Participant shall have all voting, dividend, liquidation and
other rights with respect to the shares of Common Stock issued to the
Participant as a Stock Bonus under this Article 8 upon the Participant becoming
the holder of record of such Stock Bonus; provided, however, that the Committee
may impose such restrictions on the assignment or transfer of a Stock Bonus as
it in its sole discretion deems appropriate.  As soon as practicable after the
grant of a Stock Bonus, the Participant shall be recorded on the stock transfer
books of the Company as the owner of the shares granted, and the Company shall
deliver to the Participant one or more duly issued stock certificates evidencing
such ownership.

The determination of whether to grant such a cash bonus, the nature and amount
of any such cash bonus and the terms and conditions of such cash bonus shall be

       EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE ON INCENTIVE AWARDS

 10.1.   TERMINATION OF EMPLOYMENT OR OTHER SERVICE DUE TO DEATH, DISABILITY OR
         RETIREMENT.  Except as otherwise provided in Article 12 of the Plan,
         in the event a Participant's employment or other service with the
         Company and all Subsidiaries is terminated by reason of such
         Participant's death, Disability or Retirement:

         (a)  All outstanding Options then held by the Participant shall, with
              respect to termination by reason of death or Disability, become
              immediately exercisable in full and remain exercisable for a
              period of one year after such termination and shall, with respect
              to termination by reason of Retirement, remain exercisable to the
              extent exercisable as of such termination for a period of three
              months after such termination (but in no event shall such Options
              be exercisable after the expiration date of any such Option); and

         (b)  All Restricted Stock Awards then held by the Participant shall
              become fully vested and the shares related thereto shall become
              nonforfeitable.

 10.2.   TERMINATION OF EMPLOYMENT OR OTHER SERVICE FOR REASONS OTHER THAN
         DEATH, DISABILITY OR RETIREMENT.  Except as otherwise provided in
         Article 12 of the Plan, in the event a Participant's employment or
         other service is terminated with the Company and all Subsidiaries for
         any reason other than death, Disability or Retirement, all rights of
         the Participant under the Plan and any agreement evidencing an
         Incentive Award shall immediately terminate without notice of any
         kind, no Options then held by the Participant shall thereafter be
         exercisable and any portions of the Restricted Stock Awards then held
         by the Participant that have not vested shall be terminated and all
         shares of Common Stock related thereto shall be forfeited to the
         Company; provided, however, that if such termination is due to any
         reason other than voluntary termination by the Participant or
         termination by the Company or any Subsidiary for "cause," all
         outstanding Options then held by such Participant shall remain
         exercisable to the extent exercisable as of such termination for a
         period of three months after such termination (but in no event after
         the expiration date of any such Option).  For purposes of this Section
         10.2 "cause" shall be as defined in any employment or other agreement
         or policy applicable to the Participant or, if no such agreement or
         policy exists, shall mean (a) dishonesty, fraud, misrepresentation,
         embezzlement or material or deliberate injury or attempted injury, in
         each case related to the Company or any Subsidiary, (b) any unlawful
         or criminal activity of a serious nature, (c) any willful breach of
         duty, habitual neglect of duty or unreasonable job performance, or (d)
         any

<PAGE>

         material breach of a confidentiality or noncompete agreement entered
         into with the Company or any Subsidiary.

 10.3.   MODIFICATION OF EFFECT OF TERMINATION.  Notwithstanding the provisions
         of this Article 10, upon a Participant's termination of employment or
         other service with the Company and all Subsidiaries, the Committee
         may, in its sole discretion (which may be exercised before or
         following such termination), cause Incentive Awards, or any portions
         thereof, then held by such Participant to become exercisable and
         remain exercisable following such termination, or to vest or become
         free of restrictions following such termination, in each case in the
         manner determined by the Committee; provided, however, that no Option
         shall be exercisable after the expiration date thereof and any
         Incentive Stock Option that remains unexercised more than three months
         following employment termination by reason of Retirement or more than
         one year following employment termination by reason of Disability
         shall thereafter be deemed to be a Non-Statutory Stock Option.

 10.4.   DATE OF TERMINATION.  Unless the Committee shall otherwise determine
         in its sole discretion at the time an Incentive Award is granted, a
         Participant's employment or other service shall, for purposes of the
         Plan, be deemed to have terminated on the date the Participant ceases
         to perform services for the Company, as determined by the Committee in
         its sole discretion based upon the Company's personnel records.

         stock received upon exercise of an Incentive Stock Option, or (ii)

         the Participant promptly to remit the amount of such withholding to

         (a)  Without limiting the generality of Section 11.1 of the Plan, the
              Committee may, in its sole discretion and subject to such rules
              as the Committee may adopt, permit a Participant to satisfy, in
              whole or in part, any withholding or employment-related tax
              obligation (i) attributable to the grant, exercise or vesting of,
              or payment of dividends with respect to, an Incentive Award or to
              a disqualifying disposition of stock received upon exercise of an
              Incentive Stock Option, or (ii) otherwise incurred with respect
              to an Incentive Award, by electing to use Previously Acquired
              Shares or by electing to have the Company accept a Broker
              Exercise Notice with respect to that number of shares, in any
              such case, having a Fair Market Value, on the Tax Date, equal to
              the amount necessary to satisfy the withholding or
              employment-related taxes due or by agreeing to deliver to the
              Company a promissory note in payment for some or all of the
              necessary

              amounts (containing terms and conditions determined in the
              discretion of the Committee).

         (b)  A Participant's election to use Previously Acquired Shares, a
              Broker Exercise Notice or a promissory note must be made on or
              prior to the Tax Date, is irrevocable and is subject to the
              consent or disapproval of the Committee.  If the Participant is
              an officer, director or beneficial owner of more than 10% of the
              outstanding Common Stock of the Company and the Company has a
              class of equity securities registered under Section 12 of the
              Exchange Act, an election to use Previously Acquired Shares may
              not be made within six months of the date the Incentive Award is
              granted (unless the death or Disability of the Participant occurs
              prior to the expiration of such six-month period), and must be
              made either six months prior to the Tax Date or at any time prior
              to the Tax Date between the third and twelfth business days
              following public release of any of the Company's quarterly or
              annual summary earnings statements.  When shares of Common stock
              are issued prior to the Tax Date to a Participant making an
              election to use Previously Acquired Shares, the Participant shall
              agree in writing to surrender that number of shares on the Tax
              Date having an aggregate Fair Market Value equal to the tax due.

                                  CHANGE OF CONTROL

 12.1.   CHANGE IN CONTROL.  For purposes of this Article 12, a "Change in
         Control" of the Company shall mean (a) the sale, lease, exchange or
         other transfer of all or substantially all of the assets of the
         Company (in one transaction or in a series of related transactions) to
         a corporation that is not controlled by the Company, (b) the approval
         by the shareholders of the Company of any plan or proposal for the
         liquidation or dissolution of the Company, or (c) a change in control
         of the Company of a nature that would be required to be reported
         (assuming such event has not been "previously reported") in response
         to Item 1(a) of the Current Report on Form 8-K, as in effect on the
         effective date of the Plan, pursuant to Section 13 or 15(d) of the
         Exchange Act, whether or not the Company is then subject to such
         reporting requirement; provided, however, that, without limitation,
         such a Change in Control shall be deemed to have occurred at such time
         as (x) any Person becomes after the effective date of the Plan the
         "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
         directly or indirectly, of 50% or more of the combined voting power of
         the Company's outstanding securities ordinarily having the right to
         vote at elections of directors, or (y) individuals who constitute the
         board of directors of the Company on the effective date of the Plan
         cease for any reason to constitute at least a majority thereof,
         provided that any person becoming a director subsequent to the
         effective date of the Plan whose election, or nomination for election
         by the Company's shareholders, was approved by a vote of at least a
         majority of the directors comprising the board of directors of the
         Company on the effective date of the Plan (either by a specific vote
         or by approval of the proxy statement of the Company in which such
         person is named as a nominee for director, without objection to such
         nomination) shall be, for purposes of this clause (y), considered as
         though such person were a member of the board of directors of the
         Company on the effective date of the Plan.

 12.2.   ACCELERATION OF VESTING.  If a Change of Control of the Company shall
         occur, then, without any action by the Committee or the Board, (a) all
         outstanding Options shall become immediately exercisable in full and
         shall remain exercisable during the remaining term thereof, regardless
         of


                                          13


<PAGE>

         whether the Participants to whom such Options have been granted remain
         in the employ or service of the Company or any Subsidiary, and (b) all
         restrictions with respect to outstanding Restricted Stock Awards shall
         immediately lapse and the shares related thereto shall become
         nonforfeitable.

 12.3.   CASH PAYMENT FOR OPTIONS.  If a Change in Control of the Company shall
         occur, then the Committee, in its sole discretion, and without the
         consent of any Participant effected thereby, may determine that some
         or all Participants holding outstanding Options shall receive, with
         respect to some or all of the shares of Common Stock subject to such
         Options, as of the effective date of any such Change in Control of the
         Company, cash in an amount equal to the excess of the Fair Market
         Value of such shares immediately prior to the effective date of such
         Change in Control of the Company over the exercise price per share of
         such Options.

 12.4.   LIMITATION ON CHANGE IN CONTROL PAYMENTS.  Notwithstanding anything in
         Section 12.2 or 12.3 above to the contrary, if, with respect to a
         Participant, the acceleration of the vesting of an Incentive Award as
         provided in Section 12.2 or the payment of cash in exchange for all or
         part of an Option as provided in Section 12.3 above (which
         acceleration or payment could be deemed a "payment" within the meaning
         of Section 280G(b)(2) of the Code), together with any other payments
         which such Participant has the right to receive from the Company or
         any corporation which is a member of an "affiliated group" (as defined
         in Section 1504(a) of the Code without regard to Section 1504(b) of
         the Code) of which the Company is a member, would constitute a
         "parachute payment" (as defined in Section 280G(b)(2) of the Code),
         then the payments to such Participant pursuant to Section 12.2 or 12.3
         above shall be reduced to the largest amount as will result in no
         portion of such payments being subject to the excise tax imposed by
         Section 4999 of the Code.

           RIGHTS OF ELIGIBLE RECIPIENTS AND PARTICIPANTS; TRANSFERABILITY

 13.1.   EMPLOYMENT OR SERVICE.  Nothing in the Plan shall interfere with or
         limit in any way the right of the Company or any Subsidiary to
         terminate the employment or service of any Eligible Recipient or
         Participant at any time, nor confer upon any Eligible Recipient or
         Participant any right to continue in the employ or service of the
         Company or any Subsidiary.

 13.1.   RESTRICTIONS ON TRANSFER.  Except as expressly permitted by this Plan,
         no right or interest of any Participant in an Incentive Award may be
         Transferred.  Notwithstanding the foregoing and subject to Articles 10
         and 11 of the Plan, in the event of a Participant's death, such
         Participant's rights and interests in any outstanding Options that are
         exercisable at the time of his death may be transferred by
         testamentary will or the laws of descent and distribution and may be
         exercised by such Participant's personal representative or executor
         for a period of three months following such date of death.  Any
         Transfer or attempted Transfer by any Participant in violation of this
         Section 13.2 shall be null and void and of no effect whatsoever.  By
         accepting an Incentive Award, each Participant acknowledges the
         reasonableness of the restrictions on Transfer imposed by this Plan in
         view of the Company's purposes and the purposes of this Plan.
         Accordingly, the restrictions on Transfer contained herein shall be
         specifically enforceable against any Participant attempting a Transfer
         in violation of the provisions contained herein.

         compensation plans or programs entered into by the Company.  The Plan
         will be construed to be in addition to any and all such other plans or
         programs.  Neither the adoption of the Plan nor the submission of the
         Plan to the shareholders of the Company for approval will be construed
         as creating any limitations on the power or authority of the Board to
         adopt such additional or other compensation arrangements as the Board
         may deem necessary or desirable.

         required to issue or deliver any certificate for shares of Common
         Stock under this Plan, and an Option shall not be considered to be
         exercised notwithstanding the tender by the Participant of any
         consideration therefor, unless and until each of the following
         conditions has been fulfilled:

         (a)  (i) there shall be in effect with respect to such shares a
              registration statement under the Securities Act and any
              applicable state securities laws if the Committee, in its sole
              discretion, shall have determined to file, cause to become
              effective and maintain the effectiveness of such registration
              statement; or (ii) if the Committee has determined not to so
              register the shares of Common Stock to be issued under the Plan,
              (aa) exemptions from registration under the Securities Act and
              applicable state securities laws shall be available for such
              issuance (as determined by counsel to the Company) and (bb) there
              shall have been received from the Participant (or, in the event
              of death or disability, the Participant's heir(s) or legal
              representative(s)) any representations or agreements requested by
              the Company in order to permit such issuance to be made pursuant

 14.2.   SHARE TRANSFERS.  Shares of Common Stock issued pursuant to Incentive
         Awards granted under the Plan may not be Transferred except pursuant
         to registration under the Securities Act and applicable state
         securities laws or pursuant to exemptions from such registrations.
         The Company may condition the Transfer of such shares not issued
         pursuant to an effective and current registration statement under the
         Securities Act and all applicable state securities laws on the receipt
         from the party to whom the shares of Common Stock are to be so

         Stock under the Plan, each certificate representing any such shares
         shall be endorsed with a legend in substantially the following form,

              Board for purposes of the Plan, early) retirement/pension plan or
              practice of the Company or any subsidiary of the Company then
              covering the Participant.

     2.12.    "SECURITIES ACT" means the Securities Act of 1933, as amended.

3.  PLAN ADMINISTRATION.

    The Plan will be administered by a committee (the "Committee") consisting
solely of two or more members of the Board.   All questions of interpretation of
the Plan will be determined by the Committee, each determination, interpretation
or other action made or taken by the Committee pursuant to the provisions of the
Plan will be conclusive and binding for all purposes and on all persons and no
member of the Committee will be liable for any action or determination made in
good faith with respect to the Plan or any Option granted under the Plan.  The
Committee, however, will have no power to determine the eligibility for
participation in the Plan, the number of shares of Common Stock to be subject to
Options, or the timing, pricing or other terms and conditions of Options.

4.  SHARES AVAILABLE FOR ISSUANCE.

     4.1.     MAXIMUM NUMBER OF SHARES AVAILABLE.  Subject to adjustment as
              provided in Section 4.3 of  the Plan, the maximum number of
              shares of Common Stock that will be available for issuance under
              the Plan will be 250,000 shares.  The shares available for
              issuance under the Plan shall be authorized but unissued shares.

     4.2.     ACCOUNTING FOR OPTIONS.  Shares of Common Stock that are issued
              under the Plan or that are subject to outstanding Options will be
              applied to reduce the maximum number of shares of Common Stock
              remaining available for issuance under the Plan.  Any shares of
              Common Stock that are subject to an Option that lapses, expires,
              or for any reason is terminated unexercised will automatically
              again become available for issuance under the Plan.

     4.3.     ADJUSTMENTS TO SHARES AND OPTIONS.  In the event of any
              reorganization, merger, consolidation, recapitalization,
              liquidation, reclassification, stock dividend, stock split,
              combination of shares, rights offering, divestiture or
              extraordinary dividend (including a spin-off) or any other change
              in the corporate structure or shares of the Company, the
              Committee (or, if the Company is not the surviving corporation in
              any such transaction, the board of directors of the surviving
              corporation) will make appropriate adjustment (which
              determination will be conclusive) as to the number and kind of
              securities available for issuance under the Plan and, in order to
              prevent dilution or enlargement of the rights of Eligible
              Directors, the number, kind and exercise price of securities
              subject to outstanding Options.

5.  OPTIONS.

     5.1.     GRANTS OF OPTIONS.  Subject to the terms and conditions of the
              Plan, the Committee will grant Options to each Eligible Director
              as follows:

              (a)  GRANT ON INITIAL ELECTION.  Upon each Eligible Director's
                   Initial Election (defined below), the Eligible Director will
                   be granted, on a one-time basis, an Option to purchase
                   10,500 shares of Common Stock (subject to adjustment as
                   provided in Section 4.3 of the Plan).  "Initial Election"
                   means (A) in the case of an Eligible Director serving on the
                   Board at the effective date of the Plan as set forth in
                   Section 11 of the Plan, such effective date; or (B) in the
                   case of an Eligible Director appointed or elected to serve
                   as a director after the effective date of the Plan, the date
                   such Eligible Director is first appointed or elected.  The
                   date of grant for Options granted pursuant to this Section
                   5.1(a) will be the date of Initial Election.

              (b)  ANNUAL GRANTS.  In addition to grants upon Initial Election,
                   each Eligible Director who continues to serve as an Eligible
                   Director as of the conclusion of each Annual Meeting of
                   Shareholders of the Company occurring after the second
                   anniversary of the Initial Election will be granted an
                   Option to purchase 3,500 shares of Common Stock (subject to
                   adjustment as provided in Section 4.3 of the Plan).  The
                   date of grant for Options granted pursuant to this Section
                   5.1(b) will be the date of each such Annual Meeting.

     5.2.     EXERCISE PRICE.  The per share price to be paid by an Eligible
              Director upon exercise of an Option will be 100% of the Fair
              Market Value of one share of Common Stock on the date of grant.
              The total purchase price of the shares to be purchased upon
              exercise of an Option must be paid entirely in cash (including
              check, bank draft or money order) or by delivery to the Company
              of unencumbered Previously Acquired Shares having an aggregate
              Fair Market Value on the date of exercise equal to the purchase
              price, or by a combination of cash and such unencumbered
              Previously Acquired Shares; provided, however, that no Eligible
              Director may pay any portion of the exercise price with
              Previously Acquired Shares if such payment would cause the
              Company to incur compensation expense for financial accounting
              purposes under generally accepted accounting principles.

     5.3.     EXERCISABILITY AND DURATION.  Options granted pursuant to Section
              5.1(a) will become exercisable on a cumulative basis as follows:

              SHARES              DATE FIRST EXERCISABLE
              ------              ----------------------
              3,500               Initial Election
              3,500               First anniversary of Initial Election
              3,500               Second anniversary of Initial Election


                                          3


<PAGE>

              Options granted pursuant to Section 5.1(b) will become
              exercisable in full on the first anniversary of the date of
              grant.  Each Option will expire and will no longer be exercisable
              at 5:00 p.m., Minneapolis time, on a date 10 years from its date
              of grant.

     5.4.     MANNER OF EXERCISE.  An Option may be exercised by an Eligible
              Director in whole or in part from time to time, subject to the
              conditions  contained  in  the  Plan  and  in  the  agreement
              evidencing such Option, by delivery in person, by facsimile or
              electronic transmission or through the mail of written notice of
              exercise to the Company at its principal executive office in
              Plymouth, Minnesota and by paying in full the total exercise
              price for the shares of Common Stock to be purchased in
              accordance with Section 5.2 of the Plan.

     5.5.     RIGHTS AS A SHAREHOLDER.  As a holder of Options, an Eligible
              Director will have no rights as a shareholder unless and until
              such Options are exercised for shares of Common Stock and the
              Eligible Director becomes the holder of record of such shares.
              Accordingly, no adjustment will be made for dividends or
              distributions with respect to Options as to which there is a
              record date preceding the date the Eligible Director becomes the
              holder of record of such shares.

     5.6.     EFFECT OF TERMINATION OF SERVICE AS DIRECTOR.

         (a)  TERMINATION DUE TO DEATH, DISABILITY OR RETIREMENT.  In the event
              an Eligible Director's service as a director of the Company is
              terminated by reason of death, Disability or Retirement, all
              outstanding Options then held by the Eligible Director will
              become immediately exercisable in full and will remain
              exercisable for a period of one year after such death, Disability
              or Retirement (but in no event after the expiration date of any
              such Options).

         (b)  TERMINATION FOR REASONS OTHER THAN DEATH, DISABILITY OR
              RETIREMENT.  In the event an Eligible Director's service as a
              director of the Company is terminated for any reason other than
              death, Disability or Retirement, all outstanding Options then
              held by the Eligible Director will remain exercisable to the
              extent exercisable as of such termination for a period of three
              months after such termination (but in no event after the
              expiration date of any such Options).

     5.7.     NON-DISCRETIONARY GRANTS.  Options granted to Eligible Directors
              pursuant to this Plan are intended to qualify as "formula awards"
              within the meaning of Rule 16b-3 under the Exchange Act.  As a
              result, other than as provided in Section 10 of the Plan, the
              Committee will not have the authority to amend the eligibility
              requirements for, modify the terms or accelerate the
              exercisability of, or exercise discretion with respect to, such
              Options, if such amendment, modification, acceleration or
              exercise of discretion would disqualify such Options from
              treatment as "formula awards," and any provision of this Plan
              that is inconsistent with the foregoing will be deemed to be null
              and void AB INITIO.

6.  DATE OF TERMINATION OF SERVICE AS A DIRECTOR.

    An Eligible Director's service as a director of the Company will, for
purposes of the Plan, be deemed to have terminated on the date recorded on the
books and records of the Company, as interpreted by the Committee based upon
such books and records.

7.  RIGHTS OF ELIGIBLE DIRECTORS; TRANSFERABILITY OF INTERESTS.

     7.1.     SERVICE  AS  A DIRECTOR.   Nothing  in the Plan will interfere
              with or limit in any way the right of the Company to terminate
              the service of any Eligible Director at any time, and neither the
              Plan, nor the granting of an Option nor any other action taken
              pursuant to the Plan, will constitute or be evidence of any
              agreement or understanding, express or implied, that the Company
              will retain an Eligible Director for any period of time or at any
              particular rate of compensation.

     7.2.     RESTRICTIONS ON TRANSFER OF INTERESTS.  Except pursuant to
              testamentary will or the laws of descent and distribution or as
              otherwise expressly permitted by the Plan, no right or interest
              of any Eligible Director in an Option prior to the exercise of
              such Option will be assignable or transferable, or subjected to
              any lien,  during  the  lifetime  of  the  Eligible  Director,
              either voluntarily or involuntarily, directly or indirectly, by
              operation of law or otherwise.   An Eligible Director will,
              however, be entitled to designate a beneficiary to receive an
              Option upon such Eligible Director's death, and, in the event of
              an Eligible Director's death, payment of any amounts due under
              the Plan will be made to, and exercise of any Options (to the
              extent permitted pursuant to Section 5 of the Plan) may be made
              by, the Eligible Director's legal representatives, heirs and
              legatees.

     7.3.     NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is
              intended to modify or rescind any previously approved
              compensation plans or programs of the Company or create any
              limitations on the power or authority of the Board to adopt such
              additional or other compensation arrangements as the Board may
              deem necessary or desirable.

8.  SECURITIES LAW AND OTHER RESTRICTIONS.

    Notwithstanding any other provision of the Plan or any agreements entered
into pursuant to the Plan, the Company will not be required to issue any shares
of Common Stock under this Plan, and an Eligible Director may not sell,  assign,
transfer or otherwise dispose of shares of Common Stock issued pursuant to an
Option granted under the Plan, unless (a) there is in effect with respect  to
such  shares  a  registration  statement  under  the Securities Act and any
applicable state securities laws or an exemption from such registration under
the Securities Act and applicable state securities laws, and (b) there has been
obtained any other consent, approval or permit from any other regulatory body
that the Committee, in its sole discretion, deems necessary or advisable.  The
Company may condition such issuance, sale or transfer upon the receipt of any
representations or agreements from the  parties  involved,  and the  placement
of  any  legends  on certificates representing shares of Common Stock, as may be
deemed necessary or advisable by the Company in order to comply with such
securities law or other restrictions.

9.  CHANGE OF CONTROL.

     9.1.     CHANGE IN CONTROL.  For purposes of this Section 9, a "Change in
              Control" of the Company shall mean the following: (a) the sale,
              lease exchange or other transfer of all or substantially all of
              the assets of the Company (in one transaction or in a series of
              related transactions) to a corporation that is not controlled by
              the Company; (b) the approval by the shareholders of the Company
              of any plan or proposal for the liquidation or dissolution of the
              Company; (c) any person becomes, after the effective date of the
              Plan, the "beneficial owner" (as defined in Rule 13d-3 under the
              Exchange Act), directly or


                                          5


<PAGE>

              indirectly, of 50% or more of the combined voting power of the
              Company's outstanding securities ordinarily having the right to
              vote at elections of directors; or (d) individuals who constitute
              the Board on the effective date of the Plan cease for any reason
              to constitute at least a majority thereof, provided that any
              person becoming a director subsequent to the effective date of
              the Plan whose election, or nomination for election by the
              Company's shareholders, was approved by a vote of at least a
              majority of the directors comprising the Board on the effective
              date of the Plan (either by a specific vote or by approval of the
              proxy statement of the Company in which such person is named as a
              nominee for director, without objection to such nomination) shall
              be, for purposes of this clause (d), considered as though such
              person were a member of the Board on the effective date of the
              Plan.

     9.2.     ACCELERATION OF EXERCISABILITY.  If a Change of Control of the
              Company shall occur, then, without any action by the Committee or
              the Board, all outstanding Options shall become immediately
              exercisable in full and shall remain exercisable during the
              remaining term thereof, regardless of whether the Eligible
              Directors to whom such Options have been granted remain directors
              of the Company.

10. PLAN AMENDMENT, MODIFICATION AND TERMINATION.

    The Board may suspend or terminate the Plan or any portion thereof at any
time, and may amend the Plan from time to time in such respects as the Board may
deem advisable in order that Options granted under the Plan will conform to any
change in applicable laws or regulations or in any other respect the Board may
deem to be in the best interests of the Company; provided, however, that (a) no
amendments to the Plan will be effective without approval of the shareholders of
the Company if shareholder approval of the amendment is then required pursuant
to Rule 16b-3 under the Exchange Act or the rules of the National Association of
Securities Dealers Automated Quotation ("Nasdaq") System, and (b) to the extent
prohibited by Rule 16b-3 of the Exchange Act, the Plan may not be amended more
than once every six months.  No termination, suspension or amendment of the Plan
may adversely affect any outstanding Option without the consent of the affected
Eligible Director; provided, however, that this sentence will not impair the
right of the Committee to take whatever action it deems appropriate under
Section 4.3 of the Plan.

11. EFFECTIVE DATE AND DURATION OF THE PLAN.

    Subject to approval by the shareholders of the Company, the Plan is
effective as of August 1, 1995, the date it was adopted by the Board.  The Plan
will terminate at midnight on August 1, 2005 and may be terminated prior thereto
by Board action.  No Options may be granted after termination of the Plan.
Options outstanding upon termination of the Plan, however, may continue to be
exercised in accordance with their terms.

              administration and effect of the Plan and any rules,  regulations
              and actions relating to the Plan will be governed by and
              construed exclusively in accordance with the laws of the State of

                                 [AVECOR LETTERHEAD]



______________, 1997



[NAME]
[ADDRESS]



Dear ______________:

    You are presently the _______________________ of AVECOR Cardiovascular
Inc., a Minnesota corporation.  The Company considers the establishment and
maintenance of a sound and vital management to be essential to protecting and
enhancing the best interests of the Company and its stockholders. In this
connection, the Company recognizes that, as is the case with many publicly held
corporations, the possibility of a Change in Control may arise and that such
possibility and the uncertainty and questions which it may raise among
management may result in the departure or distraction of management personnel to
the detriment of the Company and its stockholders.

    Accordingly, the Board has determined that appropriate steps should be
taken to minimize the risk that Company management will depart prior to a Change
in Control, thereby leaving the Company without adequate management personnel
during such a critical period, and that appropriate steps also be taken to
reinforce and encourage the continued attention and dedication of members of the
Company's management to their assigned duties without distraction in
circumstances arising from the possibility of a Change in Control. In
particular, the Board believes it important, should the Company or its
stockholders receive a proposal for transfer of control, that you be able to
continue your management responsibilities without being influenced by the
uncertainties of your own personal situation.

    The Board recognizes that continuance of your position with the Company
involves a substantial commitment to the Company in terms of your personal life
and professional career and the possibility of foregoing present and future
career opportunities, for which the Company receives substantial benefits.
Therefore, to induce you to remain in the employ of the Company, this Agreement,
which has been approved by the Board, sets forth the benefits which the Company
agrees will be provided to you in the event your employment with the Company is
terminated in connection with a Change in Control under the circumstances
described below.

1.  DEFINITIONS.  The following terms will have the meaning set forth below
unless the context clearly requires otherwise. Terms defined elsewhere in this
Agreement will have the same meaning throughout this Agreement.

    (a)  "AGREEMENT" means this letter agreement as amended, extended or
    renewed from time to time in accordance with its terms.

<PAGE>

Page 2

    (b)  "BOARD" means the board of directors of the Company duly qualified and
    acting at the time in question.

    (c)  "CAUSE" means: (i) your willful and continued failure to perform
    substantially your duties with the Company (other than any such failure (1)
    resulting from your Disability or incapacity due to bodily injury or
    physical or mental illness or (2) relating to changes in your duties after
    a Change in Control which constitute Good Reason) after a demand for
    substantial performance is delivered to you by the chair of the Board which
    specifically identifies the manner in which you have not substantially
    performed your duties and provides for a reasonable period of time within
    which you may take corrective actions; or (ii) your conviction (including a
    plea of nolo contendere) of willfully engaging in illegal conduct
    constituting a felony or gross misdemeanor under federal or state law which
    is materially and demonstrably injurious to the Company. For purposes of
    this definition, no act, or failure to act, on your part will be considered
    "willful" unless done, or omitted to be done, by you in bad faith and
    without reasonable belief that your action or omission was in, or not
    opposed to, the best interests of the Company. Any act, or failure to act,
    based upon authority given pursuant to a resolution duly adopted by the
    Board (or a committee thereof) or based upon the advice of counsel for the
    Company will be conclusively presumed to be done, or omitted to be done, by
    you in good faith and in the best interests of the Company. It is also
    expressly understood that your attention to matters not directly related to
    the business of the Company will not provide a basis for termination for
    Cause so long as the Board did not expressly disapprove in writing of your
    engagement in such activities either before or within a reasonable period
    of time after the Board knew or could reasonably have known that you
    engaged in those activities. Notwithstanding the foregoing, you will not be
    deemed to have been terminated for Cause unless and until there has been
    delivered to you a copy of a resolution duly adopted by the affirmative
    vote of not less than a majority of the entire membership of the Board at a
    meeting of the Board called and held for the purpose (after reasonable
    notice to you and an opportunity for you, together with your counsel, to be
    heard before the Board), finding that in the good faith opinion of the
    Board you were guilty of the conduct set forth above in clauses (i) or (il)
    of this definition and specifying the particulars thereof in detail.

    (d)  "CHANGE IN CONTROL" means: (i) the sale, lease, exchange, or other
    transfer of all or substantially all of the assets of the Company (in one

months following the month during which a Change in Control occurs if a Change

3.  BENEFITS UPON A CHANGE IN CONTROL TERMINATION.  You will become entitled to
the payments and benefits described in clauses (i) and (ii) of this Section 3,
subject to the limitations described in clause (iii) of this Section 3, if and
only if (a) your employment by the Company is terminated for any reason other

         period terminating thirty-six (36) months after the Date of
         Termination, all insured and self-insured employee welfare benefit
         Plans (including, without limitation, medical, life, dental, vision
         and disability plans) in which you were eligible to participate at any
         time during the ninety (90)-day period immediately preceding the

         applicable funding media and without regard to any discretionary
         amendments to such Plans by the Company following the Change in
         Control (or prior to the Change in Control if amended as a condition
         or at the request or insistence of a Person (other than the Company)
         related to the Change in Control) and provided that you continue to
         pay an amount equal to your regular contribution under such Plans for
         such participation (based upon your level of benefits and employment
         status most favorable to you at any time during the ninety (90)-day
         period immediately preceding the Change in Control).  The continuation
         period under federal and state continuation laws, to the extent
         applicable, will begin to run from the date on which coverage pursuant
         to the clause (ii) ends.  If, at the end of the thirty-six (36)-month
         period, you have not previously received or are not then receiving
         equivalent benefits from a new employer (including coverage for any
         pre-
<PAGE>

Page 7

         existing conditions), the Company will arrange, at its sole cost
         and expense, to enable you to convert your and your dependents'
         coverage under such Plans to individual policies or programs upon the
         same terms as executives of the Company may apply for such
         conversions. In the event that your or your dependents' participation
         in any such Plan is barred, the Company, at its sole cost and expense,
         will arrange to have issued for the benefit of you and your dependents
         individual policies of insurance providing benefits substantially
         similar (on a federal, state and local income and employment after-tax
         basis) to those which you otherwise would have been entitled to
         receive under such Plans pursuant to this clause (ii) or; if such
         insurance is not available at a reasonable cost to the Company, the
         Company will otherwise provide you and your dependents equivalent
         benefits (on a federal, state and local income and employment
         after-tax basis). You will not be required to pay any premiums or
         other charges in an amount greater than that which you would have paid
         in order to participate in such Plans.

         (iii)     LIMITATION ON PAYMENTS AND BENEFITS.  Notwithstanding
         anything in this Agreement to the contrary, if any of the payments or
         benefits to be made or provided in connection with this Agreement,
         together with any other payments or benefits which you have the right
         to receive from the Company or any corporation which is a member of an
         "affiliated group" (as defined in section 1504(a) of the Code without
         regard to section 1504(b) of the Code) of which the Company is a
         member constitute an "excess parachute payment" (as defined in section
         280G(b) of the Code), the payments or benefits to be made or provided
         in connection with this Agreement will be reduced to the extent
         necessary to prevent any portion of such payments or benefits from
         becoming subject to the excise tax imposed under section 4999 of the
         Code.  The determination as to whether any such decrease in the
         payments or benefits to be made or provided in connection with this
         Agreement is necessary must be made in good faith by legal counsel or
         a certified public accountant selected by you and reasonably
         acceptable to the Company, and such determination will be conclusive
         and binding upon you and the Company. In the event that such a
         reduction is necessary, you will have the right to designate the
         particular payments or benefits that are to be reduced or eliminated
         so that no portion of the payments or benefits to be made or provided
         to you in connection with this Agreement will be excess parachute
         payments subject to the excise tax under Code section 4999. The
         Company will pay or reimburse you on demand for the reasonable fees,
         costs and expenses of the counsel or accountant selected to make the
         determinations under this clause (iii).

4.  INDEMNIFICATION. Following a Change in Control, the Company will indemnify
and advance expenses to you to the full extent permitted by law and the
Company's articles of incorporation and bylaws for damages, costs and expenses
(including, without limitation, judgments, fines, penalties, settlements and
reasonable fees and expenses of your counsel) incurred in connection with all
matters, events and transactions relating to your service to or status with the
Company or any other corporation, employee benefit plan or other entity with
whom you served at the request of the Company.

5.  CONFIDENTIALITY.  You will not use, other than in connection with your
employment with the Company, or disclose any Confidential Information to any
person not employed by the Company or not authorized by the Company to receive
such Confidential Information, without the prior written consent of the Company;
and you will use reasonable and prudent care to safeguard and protect and
prevent the unauthorized disclosure of Confidential Information. Nothing in this
Agreement will prevent you from

<PAGE>

Page 8

using, disclosing or authorizing the disclosure of any Confidential Information:
(a) which is or hereafter becomes part of the public domain or otherwise becomes
generally available to the public through no fault of yours; (b) to the extent
and upon the terms and conditions that the Company may have previously made the
Confidential Information available to certain persons; or (c) to the extent that
you are required to disclose such Confidential Information by law or judicial or
administrative process.

6.  SUCCESSORS.  The Company will seek to have any Successor, by agreement in
form and substance satisfactory to you, assent to the fulfillment by the Company
of the Company's obligations under this Agreement. Failure of the Company to
obtain such assent at least three (3) business days prior to the time a Person
becomes a Successor (or where the Company does not have at least three (3)
business days' advance notice that a Person may become a Successor, within one
(1) business day after having notice that such Person may become or has become a
Successor) will constitute Good Reason for termination by you of your
employment.

7.  FEES AND EXPENSES.  The Company, upon demand, will pay or reimburse you for
all reasonable legal fees, court costs, experts' fees and related costs and
expenses incurred by you in connection with any actual, threatened or
contemplated litigation or legal, administrative, arbitration or other
proceeding relating to this Agreement to which you are or reasonably expect to
become a party, whether or not initiated by you, including, without limitation: 
(a) all such fees and expenses, if any, incurred in contesting or disputing any
such termination; or (b) your seeking to obtain or enforce any right or benefit
provided by this Agreement; provided, however; you will be required to repay
(without interest) any such amounts to the Company to the extent that a court
issues a final and non-appealable order setting forth the determination that the
position taken by you was frivolous or advanced by you in bad faith.

8.  BINDING AGREEMENT.  This Agreement inures to the benefit of, and is
enforceable by, you, your personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If you
die while any amount would still be payable to you under this Agreement if you
had continued to live, all such amounts, unless otherwise provided in this
Agreement, will be paid in accordance with the terms of this Agreement to your
devisee, legatee or other designee or; if there be no such designee, to your
estate.

9.  NO MITIGATION.  You will not be required to mitigate the amount of any
payments or benefits the Company becomes obligated to make or provide to you in
connection with this Agreement by seeking other employment or otherwise. The
payments or benefits to be made or provided to you in connection with this
Agreement may not be reduced, offset or subject to recovery by the Company by
any payments or benefits you may receive from other employment or otherwise.

10. NO SETOFF.  The Company will have no right to setoff payments or benefits
owed to you under this Agreement against amounts owed or claimed to be owed by
you to the Company under this Agreement or otherwise.

11. TAXES.  All payments and benefits to be made or provided to you in
connection with this Agreement will be subject to required withholding of
federal, state and local income, excise and employment-related taxes.

accordance with these provisions, except that notice of change of address will
be effective only upon receipt.

13. DISPUTES.  Any dispute, controversy or claim for damages arising under or
in connection with this Agreement may, in your sole discretion, be settled
exclusively by such judicial remedies that you may seek to pursue or by
arbitration in Minneapolis, Minnesota by three (3) arbitrators in accordance
with the rules of the American Arbitration Association then in effect. Judgment

of competent jurisdiction (within or without the State of Minnesota) to enforce

the parties agree that any action or proceeding arising under or in connection

courts for this purpose and agree not to assert that such courts are an
inconvenient forum.

15. RELATED AGREEMENTS.  To the extent that any provision of any other Plan or
agreement between the Company and you shall limit, qualify or be inconsistent
with any provision of this Agreement, then for purposes of this Agreement, while
such other Plan or agreement remains in force, the provision of this Agreement
will control and such provision of such other Plan or agreement will be deemed
to have been superseded, and to be of no force or effect, as if such other
agreement had been formally amended to the extent necessary to accomplish such
purpose. Nothing in this Agreement prevents or limits your continuing or future
participation in any Plan provided by the Company and for which you may qualify,
and nothing in this Agreement limits or otherwise affects the rights you may
have under any Plans or other agreements with the Company. Amounts which are
vested benefits or which you are otherwise entitled to receive under any Plan or
other agreement with the Company at or subsequent to the Date of Termination
will be payable in accordance with such Plan or other agreement.

16. NO EMPLOYMENT OR SERVICE CONTRACT.  Nothing in this Agreement is intended
to provide you with any right to continue in the employ of the Company for any
period of specific duration or interfere with or otherwise restrict in any way
your rights or the rights of the Company, which rights are hereby expressly
reserved by each, to terminate your employment at any time for any reason or no
reason whatsoever; with or without cause.

17. CHANGE OF SUBSIDIARY STATUS.  In the event that, prior to a Change in
Control: (a) a Subsidiary is sold, merged, transferred or in any other manner or
for any other reason ceases to be a Subsidiary; (b) your primary employment
duties are with the Subsidiary at the time of the occurrence of such event; and
(c) you do not, in conjunction therewith, transfer employment directly to the
Company or another Subsidiary, then this Agreement will become null and void.

18. SURVIVAL.  The respective obligations of, and benefits afforded to, the
Company and you which by their express terms or clear intent survive termination
of your employment with the Company or termination of this Agreement, as the
case may be, including, without limitation, the provisions of Sections 3, 4, 5,
6, 7, 10, 11, 12 and 13 of this Agreement, will survive termination of your
employment

with the Company or termination of this Agreement, as the case may be, and will
remain in full force and effect according to their terms.

19. MISCELLANEOUS.  No provision of this Agreement may be modified, waived or
discharged unless such modification, waiver or discharge is agreed to in a
writing signed by you and the chair of the Board. No waiver by any party to this
Agreement at any time of any breach by another party to this Agreement of, or of
compliance with, any condition or provision of this Agreement to be performed by
such party will be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time.  No agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter to this Agreement have been made by any party which are not
expressly set forth in this Agreement. This Agreement and the legal relations
among the parties as to all matters, including, without limitation, matters of
validity, interpretation, construction, performance and remedies, will be
governed by and construed exclusively in accordance with the internal laws of
the State of Minnesota (without regard to the conflict of laws provisions of any
jurisdiction).  Headings are for purposes of convenience only and do not
constitute a part of this Agreement. The parties to this Agreement agree to
perform, or cause to be performed, such further acts and deeds and to execute
and deliver or cause to be executed and delivered, such additional or
supplemental documents or instruments as may be reasonably required by the other
party to carry into effect the intent and purpose of this Agreement. The
invalidity or unenforceability of all or any part of any provision of this
Agreement will not affect the validity or enforceability of the remainder of
such provision or of any other provision of this Agreement, which will remain in
full force and effect.  This Agreement may be executed in several counterparts,
each of which will be deemed to be an original, but all of which together will

                             OF CONFIDENTIAL INFORMATION,

                               OF INTELLECTUAL PROPERTY


1.  INTRODUCTION

    AVECOR Cardiovascular Inc. ("Avecor") and the undersigned Employee
acknowledge and agree that Avecor will disclose or has already disclosed to
Employee certain Confidential Information as defined in Section 2. Employee
recognizes that the Confidential Information is a business asset of Avecor, the

the course of his or her employment by Avecor, Employee will establish or has
already established personal contacts and relationships with Avecor's customers
and that such personal contacts and relationships also represent valuable
business assets of Avecor.

    Employee, therefore, enters into this Agreement in consideration of
Avecor's offer of employment or continuing employment and the benefits
associated with that employment, in consideration of being given access to
Confidential Information and for other good and valuable consideration.
Employee and Avecor, intending to be legally bound, agree as follows:

             employment with Avecor; and

       (ii)  The Standard Metropolitan Statistical Area or Areas within which
             Employee or persons under Employee's supervision sold, solicited 
             or supported the sale of any Avecor Product during the twelve (12)
             months immediately preceding the termination of Employee's 
             employment with Avecor.

    (d)  AVECOR PRODUCT means any actual or projected product, product line or
         service that has been designed, developed, manufactured, marketed or 
         sold by Avecor during Employee's employment with Avecor or regarding 
         which Avecor has conducted or acquired research and development during
         Employee's employment with Avecor.  AVECOR PRODUCT specifically 
         includes those products, product lines, services and products in 
         research and development acquired by Avecor from SciMed Life Systems,

    (e)  Competitive Product means any actual or projected product, product

    During the term of employment and for a period of two (2) years following
voluntary termination of employment, for whatever reason, Employee will not
participate in or support the manufacture, invention, development, sale,
solicitation of sale, marketing, testing, research or other business aspect of
any Competitive Product.  With regard to sales and solicitation of sales, such
restriction applies only within Employee's Area of Employment.


                                          2

<PAGE>

    To Compensate Employee for any economic hardship resulting from the
non-competition provisions of this Agreement, Avecor agrees that it will make
the monthly payment specified in this paragraph to Employee commencing with the
fourth (4th) month after termination of employment and continuing until the
non-competition provision expires or is expressly waived by Avecor, or until
Employee fails to meet one of the conditions specified below.  The monthly
payment shall be seventy-five percent (75%) of Employee's average monthly base
salary from Avecor during the preceding twelve (12) months less any compensation
which the Employee received or obtained an unqualified right to receive as the
result of being employed during the preceding month.  If Employee has not been
employed by Avecor for at least twelve (12) months prior to termination, such
average shall be taken over Employee's actual months of employment.

    Avecor's obligation to make the above-described payments is expressly
conditioned on each of the following:

    (a)  Employee will, during the entire period during which such payments are
         made, seek employment consistent with Employee's education, abilities 
         and experience which would not violate the non-competition provisions 
         of this Agreement.

    (b)  Employee will, within the first 10 days of each month for which
         payment is to be made, provide Avecor with a written summary of efforts
         made by Employee pursuant to Paragraph 3(a) above.  Simultaneously 
         Employee will inform Avecor of the amount of compensation which 
         Employee received or obtained an unqualified right to receive as 
         a result of being employed the preceding month.

    If Employee has had managerial or supervisory responsibilities, Employee
will not, for a period of two (2) years following termination of employment with
Avecor, for whatever reason, induce or attempt to induce any Avecor employee for
whom Employee had managerial or supervisory responsibilities during the twelve
(12) months immediately preceding termination of Employee's employment to leave
his or her employment with Avecor.  Such inducement includes all acts of
recruitment including offering employment, seeking expressions of interest in
employment or discussing employment opportunities.

    The restrictions contained in this Section 3 shall apply regardless of
whether Employee acts directly or indirectly; or whether Employee acts
personally or as an employee, agent or otherwise for another.  However, the
restrictions contained in this Section 3 shall not apply in the event all or
substantially all of the assets or voting shares of Avecor are acquired by any
third party.


                                          3

<PAGE>

4.  NON-DISCLOSURE OF CONFIDENTIAL INFORMATION

    Employee agrees not to disclose, during the course of Employee's employment
by Avecor or thereafter, in any manner to any person not employed by Avecor, any
Confidential Information.  Upon termination of Employee's employment with
Avecor, for whatever reason, Employee agrees to return all originals and copies
of documents containing Confidential Information as well as all documents
generated by Employee on behalf of Avecor and all documents relating to the
business of Avecor from any source whatsoever.

5.  INVENTIONS AND PATENTS

    All inventions, improvements and discoveries, whether or not patentable,
made or conceived by Employee, whether by Employee's individual efforts or in
connection with the efforts of others, during the period of Employee's
employment with Avecor and for twenty-four (24) months thereafter, whether made
during the working hours of Avecor or on Employee's own time, relating in any
way to Avecor Products or resulting in any way from employment with Avecor,
shall be the property of Avecor.  This provision shall not apply to inventions,
improvements, or discoveries meeting all of the following conditions:

    (a)  Any inventions, improvements, or discoveries which were made without
         the use of any Avecor equipment, supplies, facilities, or Confidential
         Information; and

    (b)  Which were developed entirely on Employee's own time; and

    (c)  Which do not relate directly to the business of Avecor, or to Avecor's
         actual or demonstrably anticipated research and development; and

    (d)  Which do not result in any manner from the work performed by Employee
         for Avecor.

    In the event of any dispute, arbitration or litigation concerning whether
an invention, improvement or discovery made or conceived by Employee is the
property of Avecor, such invention, improvement or discovery shall be presumed
the property of Avecor and Employee shall bear the burden of establishing
otherwise.

    Employee agrees to keep accurate, complete and timely records of all
inventions, improvements and discoveries, which records shall be the property of
Avecor and shall be retained on the premises of Avecor.


                                          4

<PAGE>

    Employee agrees to fully disclose and describe such inventions,
improvements and discoveries to Avecor promptly after their creation or
discovery.  Employee agrees to assign, and does hereby assign, to Avecor all the
Employee's rights to such inventions, improvements and discoveries and to
applications for letters patent and/or copyrights in all countries and to all
letters patent and/or copyrights granted upon such inventions, improvements and
discoveries in all countries.

    Employee agrees to assist Avecor in every reasonable way to obtain letters
patent and/or copyrights on such inventions, improvements and discoveries and to
execute all documents necessary to memorialize the assignments of such letters
patent and/or copyrights to Avecor.

    Employee agrees to perform promptly (without charge to Avecor but at the
expense of Avecor) all acts as may be necessary in Avecor's opinion to preserve
all patents and/or copyrights granted upon Employee's inventions, improvements
and discoveries against forfeiture, abandonment or loss.

    Employee has made no inventions, improvements or discoveries related to
Avecor Products or the business of Avecor prior to the date hereof that are
excluded from this Agreement except:

    (a)
       -----------------------------------------------------------------
       (If none, write "none" and cross out ensuing subparagraph (b)).

    (b)  Those inventions, improvements, and discoveries set forth on the
         attached list signed by Employee and by an officer of Avecor, a copy
         of which has been delivered to Employee with a copy of this agreement.

6.  INJUNCTIVE RELIEF

    The remedy at law for breach of this Agreement is inadequate, and
therefore, Avecor shall be entitled to injunctive relief to enforce the terms of
this Agreement, in addition to any other remedy Avecor might have.

7.  SEVERABILITY

    The invalidity of any portion of this Agreement shall not impair or affect
enforceability of the remainder.  If any of these restrictions is determined to
be unenforceable as to duration or extent, or for any reason whatsoever, such
restriction shall be effective for such period of time and for such extent as it
may be enforceable.


                                          5

<PAGE>

8.  PRIOR AGREEMENTS

    This Agreement and any prior Non-compete and Non-disclosure Agreements
signed by Employee in connection with his or her employment at Avecor shall
constitute a single agreement.  In case of conflict between any provision of
this Agreement and any provision of any other such agreement, the provisions of
this Agreement shall control.  If the provisions of this Agreement so selected
are determined to be unenforceable as written, then they shall be interpreted in
accordance with Section 7 (Severability) to make them enforceable to the maximum
extent provided by law.  If the provisions of this Agreement so selected are
determined to be unenforceable in their entirety and cannot be revised pursuant
to Section 7 (Severability) to make them enforceable, then such provisions shall
give way to the most restrictive provision in any other such agreement which
covers the same issue and which is enforceable.  There are no agreements,
representations, or warranties relating to the subject matter of this Agreement
which are not set forth in this Agreement and the prior Non-compete and
Non-disclosure agreements (if any) signed by Employee.

9.  NON-EMPLOYMENT AGREEMENT

    This Agreement is not an employment contract and does not give Employee any
right to continued employment.  Employee acknowledges that his employment with
Avecor is terminable at will at any time by either party.

10. GOVERNING LAW/CONSENT TO PERSONAL JURISDICTION

    This Agreement will be construed and enforced in accordance with the laws
of the State of Minnesota.  Employee hereby consents to the exercise of personal
jurisdictions over him or her by the courts of the State of Minnesota.

    The Borrower represents and warrants to the Lender:

    Section 4.1    ORGANIZATION, STANDING ETC. The Borrower is a corporation
duly incorporated and validly existing and in good standing under the laws of
the jurisdiction of its incorporation, and, if different, the jurisdiction in
which the Project is located, and has all requisite corporate power and
authority to own its properties and to carry on its business as now conducted,
to enter into this Agreement and the other Loan Documents to which it is a party
and to issue the Note and to perform its obligations hereunder and thereunder.
This Agreement, the Note and the other Loan Documents to which it is a party
have been duly authorized by all necessary corporate action and when executed
and delivered will be the legal and binding obligations of the Borrower. The
execution, delivery and performance of this Agreement, the Note and the other
Loan Documents to which it is a party will not violate the Borrower's Articles
of Incorporation or bylaws or any law applicable to the Borrower, and will not
violate or cause a default under or permit acceleration of any agreement to
which Borrower is a party or by which it or the Project is bound. Except for
consents, approvals and exemptions previously obtained (copies of which have
been delivered to the Lender), no approval of or exemption by any Person is
required in connection with the Borrower's execution, delivery and performance
of this Agreement, the Note and the other Loan Documents to which it is a party.
To the Borrower's knowledge, it is not in default (beyond any applicable grace
period) in the performance of any agreement, order, writ, injunction, decree or
demand to which it is a party or by which it is bound.

material obligation, liability or asset not disclosed in such financial
statements, and there has been no material adverse change in the condition of
the Borrower since the dates of such financial statements.

expected to impose a material liability on the Borrower.

$5,167,500.00                                    Minneapolis, Minnesota
                                                 January 30, 1997

    FOR VALUE RECEIVED, AVECOR CARDIOVASCULAR INC., a Minnesota corporation
("Borrower"), hereby promises to pay to the order of FIRST BANK NATIONAL
ASSOCIATION, a national banking association ("Lender", which term shall include
any future holder hereof), at 3305 Plymouth Boulevard, Plymouth, Minnesota
55447, or at such other place as Lender may from time to time designate in
writing, in lawful money of the United States of America, the principal sum of
FIVE MILLION ONE HUNDRED SIXTY-SEVEN THOUSAND FIVE HUNDRED and no/100 Dollars
($5,167,500.00) or so much thereof as may be advanced hereunder and to pay
interest on the outstanding principal balance hereof from time to time at the
rate of eight and eleven one-hundredths percent (8.11%) per annum. Interest
shall be computed on the basis of actual days elapsed and a year of 360 days.
Accrued interest from the date hereof shall be paid on the first day of
February, 1997. Commencing on the first day of March, 1997, and on the same day
of each month thereafter, Borrower shall make monthly payments equal to the sum
of (a) $21,531.25 of principal plus (b) all accrued and unpaid interest, all
payments to be applied first to accrued interest and then to reduction in
principal. The total unpaid principal amount and all interest thereon shall be
payable on February 1, 2002 (the "Maturity Date"). THIS NOTE REQUIRES A BALLOON
PAYMENT.

    Borrower may prepay this Note in whole or in part at any time upon three
(3) business days' prior written notice to Lender, and if in part from time to
time, during the entire term of this Note, provided that at the time of such
prepayment Borrower pays Lender a prepayment premium as calculated in accordance
with the following provisions of this paragraph. If at the time of any
prepayment (whether voluntary or involuntary), the Government Yield, as
hereinafter defined, is less than the Note Rate, as hereinafter defined,
Borrower shall pay to Lender a prepayment premium calculated as follows: the
amount prepaid shall be multiplied by (a) the amount by which the Note Rate
exceeds the Government Yield times (b) a fraction, the numerator of which is the
number of days remaining to the Maturity Date and the denominator of which is
360. The resulting product shall then be divided by the number of whole months
(using a 30-day month) then remaining to the Maturity Date, yielding a quotient
(the "Quotient"). The amount of the prepayment premium shall be the present
value (determined in accordance with standard financial practice) on the date of
prepayment (using the Government Yield as of the date of prepayment as the
discount factor) of a stream of equal monthly payments in number equal to the
number of whole months (using a 30-day month) then remaining to the Maturity
Date, with the amount of each hypothetical monthly payment equal to the Quotient
and with the first payment payable thirty days after the date of prepayment. The
term "GOVERNMENT YIELD" means the yield (converted as necessary to the
equivalent semi-annual compound rate) on U. S. Treasury Securities having a
maturity date closest to the Maturity Date. "U.S. Treasury Securities" means
actively traded U. S. Treasury bonds, bills and notes and, if more than one
issue of U. S. Treasury Securities is scheduled to mature on or about the
Maturity Date, then to the extent possible the U. S. Treasury Security issued
most recently prior to the date of

<PAGE>

determination will be chosen as the basis of the Government Yield. The term
"NOTE RATE" means the rate of interest payable under this Note as of the date of
determination. No prepayment shall suspend any required payments of either
principal or interest on this Note or reduce the amount of any scheduled
payment. Such prepayment premium shall be payable whether this Note is prepaid
voluntarily or involuntarily (including any such involuntary prepayment as a
result of Lender's acceleration of this Note on account of an Event of Default
(as defined in the Loan Agreement) or the exercise of Lender's rights under
"due-on-sale," "due-on-encumbrance" or similar provisions in the Mortgage, or in
connection with any bankruptcy proceeding involving the property subject to the
Mortgage or any foreclosure of such property). Notwithstanding anything to the
contrary contained herein, however, no prepayment premium shall be payable in
connection with any prepayment of this Note made with insurance proceeds or
condemnation awards or proceeds unless such insurance proceeds or condemnation
awards or proceeds are not made available to repair, rebuild or restore the
property subject to the Mortgage by reason of the existence of an Event of
Default.

    This Note is secured by a Mortgage, Security Agreement, Assignment of
Leases and Rents and Fixture Financing Statement of even date herewith (the
"Mortgage") on real property located in Hennepin County, Minnesota, therein
described. This Note is the Note referred to in the Loan Agreement of even date
herewith between Borrower and Lender (the "Loan Agreement"), and is subject to
the additional terms and conditions set forth in the Loan Agreement and the
documents referred to therein.

    If a payment due hereunder is not made within five days after the date when
due, Borrower shall pay to Lender a late payment charge of 5% of the amount of
the overdue payment to compensate Lender for a portion of the cost related to
handling the overdue payment. After an Event of Default, as defined in the Loan
Agreement, then the entire principal sum evidenced by this Note, together with
all accrued and unpaid interest, shall, at the option of the holder hereof, bear
interest at the rate per annum (the "Default Rate") equal to 5% in excess of the
rate of interest per annum which would otherwise be payable hereunder, and
become immediately due and payable without further notice (except as provided in
the Loan Agreement), demand or presentment for payment, and without any relief
whatever from any valuation or appraisement laws. Failure to exercise any option
provided herein shall not constitute a waiver of the right to exercise the same
in the event of any subsequent default. Borrower agrees that if, and as often
as, this Note is given to an attorney for collection or to defend or enforce any
of Lender's rights hereunder, Borrower will pay to the Lender Lender's
reasonable attorneys' fees together with all court costs and other expenses paid
by Lender.

    Borrower waives presentment, protest and demand, notice of protest, demand
and of dishonor and nonpayment of this Note and any lack of diligence or delays
in collection or enforcement of this Note. Borrower agrees that this Note, or
any payment hereunder, may be extended from time to time, and Borrower consents
to the release of any party liable for the obligation evidenced by this Note,
the release of any of the security for this Note, the acceptance of any other
security therefor, or any other indulgence or forbearance whatsoever, all
without notice to any party and without affecting the liability of Borrower.

comply fully with the provisions thereof, and to afford Lender, to the fullest
extent allowed by law, the rights and remedies of a mortgage lender or secured

     This Mortgage also constitutes a security agreement within the meaning of
the Uniform Commercial Code as in effect in the State of Minnesota (the "UCC"),
with respect to all property described herein as to which a security interest
may be granted and/or perfected pursuant to the UCC, and is intended to afford
Lender, to the fullest extent allowed by law, the rights and remedies of a
secured party under the UCC.

     BORROWER FURTHER agrees as follows:

                                      ARTICLE I

                                      AGREEMENTS

     SECTION 1.1    PERFORMANCE OF OBLIGATIONS; INCORPORATION BY REFERENCE.
Borrower shall pay and perform the Obligations. Time is of the essence hereof.
All of the covenants, obligations, agreements, warranties and representations of
Borrower contained in the Loan Agreement and the other Loan Documents and all of
the terms and provisions thereof, are hereby incorporated herein and made a part
hereof by reference as if fully set forth herein.

     SECTION 1.2    FURTHER ASSURANCES. If Lender requests, Borrower shall sign
and deliver and cause to be recorded as Lender shall direct any further
mortgages, instruments of further


                                          3

<PAGE>

assurance, certificates and other documents as Lender reasonably may consider
necessary or desirable in order to perfect, continue and preserve the
Obligations and Lender's rights, title, estate, liens and interests under the
Loan Documents. Borrower further agrees to pay to Lender, upon demand, all costs
and expenses incurred by Lender in connection with the preparation, execution,
recording, filing and refiling of any such documents, including attorneys' fees
and title insurance costs.

     SECTION 1.3    SALE, TRANSFER, ENCUMBRANCE. If Borrower sells, conveys,
transfers or otherwise disposes of, or encumbers, any part of its interest in
the Mortgaged Property, whether voluntarily, involuntarily or by operation of
law, without the prior written consent of Lender, Lender shall have the option
to declare the Obligations immediately due and payable without notice. Included
within the foregoing actions requiring prior written consent of Lender are: (a)
sale by deed or contract for deed; (b) mortgaging or granting a lien on the
Mortgaged Property; (c) leasing any portion of the Improvements or the Mortgaged
Property; (d) a transfer which changes the persons in control of Borrower or
which transfers more than 25% of the beneficial interest in Borrower, except for
transfers to related or affiliated entities, and (e) a transfer in the ownership
of stock of Borrower which will result in one person or entity or his, her or
its family members or affiliates controlling Borrower. Borrower shall give
notice of any proposed action to Lender at least thirty (30) days prior to
taking such action. Borrower shall pay all costs and expenses incurred by Lender
in evaluating any such action. Lender may condition such consent upon
modification of the Loan Documents or payment of fees. No such action shall
relieve Borrower from liability for the Obligations. The consent by Lender to
any action shall not constitute a waiver of the necessity of such consent to any
subsequent action.

     SECTION 1.4    INSURANCE. Borrower shall obtain, maintain and keep in full
force and effect (and upon request of Lender shall furnish to Lender copies of)
policies of insurance as described in, and meeting the requirements set forth
in, Exhibit B attached hereto, and upon request of Lender shall furnish to
Lender proof of payment of all premiums for such insurance. At least ten (10)
days prior to the termination of any such coverage, Borrower shall provide
Lender with evidence satisfactory to Lender that such coverage will be renewed
or replaced upon termination with insurance that complies with the provisions of
this Section. Borrower, at its sole cost and expense, from time to time when
Lender shall so request, will provide Lender with evidence, in a form acceptable
to Lender, of the full insurable replacement cost of the Mortgaged Property. All
property (including boiler and machinery) and liability insurance policies
maintained by Borrower pursuant to this Section shall (i) include effective
waivers by the insurer of all claims for insurance premiums against Lender, and
(ii) provide that any losses shall be payable notwithstanding (a) any act of
negligence by Borrower or Lender, (b) any foreclosure or other proceedings or
notice of foreclosure sale relating to the Mortgaged Property, or (c) any
release from liability or waiver of subrogation rights granted by the insured.
All insurance policies maintained by Borrower pursuant to the foregoing
provisions shall respond on a primary basis relative to any other insurance
carried by Lender in the event of loss. Insurance terms not otherwise defined
herein shall be interpreted consistent with insurance industry usage.

     SECTION 1.5    TAXES, LIENS AND CLAIMS, UTILITIES. Borrower, at least five
(5) days before any penalty attaches thereto, shall pay and discharge, or cause
to be paid and discharged, all


                                          4

<PAGE>

taxes, assessments and governmental charges and levies (collectively
"Impositions") imposed upon or against the Mortgaged Property or the Rents, or
upon or against the Obligations, or upon or against the interest of Lender in
the Mortgaged Property or the Obligations, except Impositions measured by the
income of Lender. Borrower shall provide evidence of such payment at Lender's
request. Borrower shall keep the Mortgaged Property free and clear of all liens,
encumbrances, easements, covenants, conditions, restrictions and reservations
(collectively "Liens") except those listed on Exhibit A attached hereto (the
"Permitted Encumbrances"). Borrower shall pay or cause to be paid when due all
charges or fees for utilities and services supplied to the Mortgaged Property.
Notwithstanding anything to the contrary contained in this Section, Borrower
shall not be required to pay or discharge any Imposition or Lien so long as
Borrower shall in good faith, and after giving notice to Lender, contest the
same by appropriate legal proceedings. If Borrower contests any Imposition or
Lien against the Mortgaged Property, Borrower shall provide such security to
Lender as Lender shall reasonably require against loss or impairment of
Borrower's ownership of or Lender's lien on the Mortgaged Property and shall in
any event pay such Imposition or Lien before loss or impairment occurs.

     SECTION 1.6    ESCROW PAYMENTS. If requested by Lender, Borrower shall
deposit with Lender monthly on the same date as payments are due under the Note
the amount reasonably estimated by Lender to be necessary to enable Lender to
pay, at least five (5) days before they become due, all Impositions against the
Mortgaged Property and the premiums upon all insurance required hereby to be
maintained with respect to the Mortgaged Property. All funds so deposited shall
secure the Obligations. Such deposits shall be held by Lender, or its nominee,
in a non-interest bearing account and may be commingled with other funds. Such
deposits shall be used to pay such Impositions and insurance premiums when due.
Any excess sums so deposited shall be retained by Lender and shall be applied to
pay said items in the future, unless the Obligations have been paid and
performed in full, in which case all excess sums so paid shall be refunded to
Borrower. Upon the occurrence of an Event of Default, Lender may apply any funds
in said account against the Obligations in such order as Lender may determine.

     SECTION 1.7    MAINTENANCE AND REPAIR; COMPLIANCE WITH LAWS. Borrower shall
cause the Mortgaged Property to be operated, maintained and repaired in safe and
good repair, working order and condition, reasonable wear and tear excepted;
shall not commit or permit waste thereof; except as provided in any Loan
Document, shall not remove, demolish or substantially alter the design or
structural character of any Improvements without the prior written consent of
Lender; shall complete or cause to be completed forthwith any Improvements which
are now or may hereafter be under construction upon the Land; shall comply or
cause compliance with all laws, statutes, ordinances and codes, and governmental
rules, regulations and requirements, applicable to the Mortgaged Property or the
manner of using or operating the same, and with any covenants, conditions,
restrictions and reservations affecting the title to the Mortgaged Property, and
with the terms of all insurance policies relating to the Mortgaged Property; and
shall obtain and maintain in full force and effect all consents, permits and
licenses necessary for the use and operation of the Mortgaged Property.

     SECTION 1.8    INDEMNITY. Borrower shall indemnify Lender and its
directors, officers, agents and employees (collectively the "Indemnified
Parties") against, and hold the Indemnified


                                          5

<PAGE>

Parties harmless from, all losses, damages, suits, claims, judgments, penalties,
fines, liabilities, costs and expenses by reason of, or on account of, or in
connection with the construction, reconstruction or alteration of the Mortgaged
Property, or any accident, injury, death or damage to any person or property
occurring in, on or about the Mortgaged Property or any street, drive, sidewalk,
curb or passageway adjacent thereto. The indemnity contained in this Section
shall include costs of defense of any such claim asserted against an Indemnified
Party, including attorneys' fees. The indemnity contained in this Section shall
survive payment and performance of the Obligations and satisfaction and release
of this Mortgage and any foreclosure thereof or acquisition of title by deed in
lieu of foreclosure.

     SECTION 1.9    APPRAISALS. Lender shall have the right from time to time,
but not more often than once during any twelve (12)-month period, to obtain an
appraisal of the Mortgaged Property in form and substance satisfactory to Lender
and prepared by an independent MAI appraiser selected by Lender. Borrower shall
reimburse Lender for the cost incurred for any such appraisal within ten (10)
days following demand therefor by Lender, if Lender has reason to believe that
the value of the Mortgaged Property has declined materially, and such appraisal
determines that the original principal amount of the Note exceeds seventy-five
percent (75%) of the value of the Mortgaged Property.

                                      ARTICLE II

                            REPRESENTATIONS AND WARRANTIES

     Borrower makes the following representations and warranties:

     SECTION 2.1    OWNERSHIP, LIENS, COMPLIANCE WITH LAWS. Borrower owns the
Mortgaged Property free from all Liens, except the Permitted Encumbrances. All
applicable zoning, environmental, land use, subdivision, building, fire, safety
and health laws, statutes, ordinances, codes, rules, regulations and
requirements affecting the Mortgaged Property permit the current use and
occupancy thereof, and Borrower has obtained all consents, permits and licenses
required for such use. Borrower has examined and is familiar with all applicable
covenants, conditions, restrictions and reservations, and with all applicable
laws, statutes, ordinances, codes and governmental rules, regulations and
requirements affecting the Mortgaged Property, and the Mortgaged Property
complies with all of the foregoing.

     SECTION 2.2    USE. The Mortgaged Property is not homestead property nor is
it agricultural property or in agricultural use.

     SECTION 2.3    UTILITIES; SERVICES. The Mortgaged Property is serviced by
all necessary public utilities, and all such utilities are operational and have
sufficient capacity. There is no contract or agreement providing for services to
or maintenance of the Mortgaged Property which cannot be canceled upon 30 days'
or less notice.

                                CASUALTY; CONDEMNATION

     SECTION 3.1    CASUALTY, REPAIR, PROOF OF LOSS. If any portion of the
Mortgaged Property shall be damaged or destroyed by any cause (a "Casualty"),
Borrower shall:

     (a)  give immediate notice to the Lender; and

     (b)  promptly commence and diligently pursue to completion (in accordance
with plans and specifications approved by Lender) the restoration, repair and
rebuilding of the Mortgaged Property as nearly as possible to its value,
condition and character immediately prior to the Casualty; and

     (c)  if the Casualty is covered by insurance, immediately make proof of
loss and collect all insurance proceeds, all such proceeds to be payable to
Lender or as Lender shall direct. If an Event of Default shall be in existence,
or if Borrower shall fail to provide notice to Lender of filing proof of loss,
or if Borrower shall not be diligently proceeding, in Lender's reasonable
opinion, to collect such insurance proceeds, then Lender may, but is not
obligated to, make proof of loss, and is authorized, but is not obligated, to
settle any claim with respect thereto, and to collect the proceeds thereof.
Borrower shall not accept any settlement of an insurance claim, the result of
which shall be a payment which is $10,000 or more less than the full amount of
the claim, without the prior written consent of Lender.

     SECTION 3.2    USE OF INSURANCE PROCEEDS. Lender shall make the net
insurance proceeds received by it (after reimbursement of Lender's out-of pocket
costs of collecting and disbursing the same) available to Borrower to pay the
cost of restoration, repair and rebuilding of the Mortgaged Property, subject to
the following conditions:

     (a)  There shall be no Event of Default in existence at the time of any
disbursement of the insurance proceeds.

     (b)  Lender shall have determined, in its reasonable discretion, that the
cost of restoration, repair and rebuilding is and will be equal to or less than
the amount of insurance proceeds and other funds deposited by Borrower with
Lender.

     (c)  Lender shall have determined, in its reasonable discretion, that the
restoration, repair and rebuilding can be completed in accordance with plans and
specifications approved by Lender (such approval not to be unreasonably
withheld), in accordance with codes and ordinances and in accordance with the
terms, and in any event not less than six (6) months prior to the Maturity Date.

     (d)  All funds shall be held in an interest-bearing account and shall be
disbursed, at Lender's option, in accordance with Lender's customary
disbursement procedures for construction loans.


                                          7

<PAGE>

     (e)  The Casualty shall have occurred more than twelve (12) months prior to
the Maturity Date.

If any of these conditions shall not be satisfied, then Lender shall have the
right to use the insurance proceeds to prepay the Loan in accordance with the
Note. If any insurance proceeds shall remain after completion of the
restoration, repair and rebuilding of the Mortgaged Property, they shall be
disbursed to Borrower, or at the Lender's discretion, used to prepay the Loan in
accordance with the Note.

     SECTION 3.3    CONDEMNATION. If any portion of the Mortgaged Property shall
be taken, condemned or acquired pursuant to exercise of the power of eminent
domain or threat thereof (a "Condemnation"), Borrower shall:

     (a)  give immediate notice thereof to Lender, and send a copy of each
document received by Borrower in connection with the Condemnation to Lender
promptly after receipt; and

     (b)  diligently pursue any negotiation and prosecute any proceeding in
connection with the Condemnation at Borrower's expense. If an Event of Default
shall be in existence, or if Borrower, in Lender's reasonable opinion, shall not
be diligently negotiating or prosecuting the claim, Lender is authorized, but
not required, to negotiate and prosecute the claim and appear at any hearing for
itself and on behalf of Borrower and to compromise or settle all compensation
for the Condemnation. Lender shall not be liable to Borrower for any failure by
Lender to collect or to exercise diligence in collecting any such compensation.
Borrower shall not compromise or settle any claim resulting from the
Condemnation if such settlement shall result in payment of $10,000 or more less
than Lender's reasonable estimate of the damages therefrom. All awards shall be
paid to Lender.

     SECTION 3.4    USE OF CONDEMNATION PROCEEDS. Lender shall make the net
proceeds of any Condemnation received by it (after reimbursement of Lender's
out-of-pocket costs of collecting and disbursing the same) available to Borrower
for restoration, repair and rebuilding of the Mortgaged Property, subject to the
following conditions:

     (a)  There shall be no Event of Default in existence at the time of any
disbursement of the condemnation proceeds.

     (b)  Lender shall determined, in its reasonable discretion, that the cost
of restoration, repair and rebuilding is and will be equal to or less than the
amount of condemnation proceeds and other funds deposited by Borrower with
Lender.

     (c)  Lender shall have determined, in its reasonable discretion, that the
restoration, repair and rebuilding can be completed in accordance with plans and
specifications approved by Lender (such approval not to be unreasonably
withheld), in accordance with codes and


                                          8

<PAGE>

ordinances and in accordance with the terms, and in any event not less than six
(6) months prior to the Maturity Date.

     (d)  All funds shall be held in an interest-bearing account and shall be
disbursed, at Lender's option, in accordance with Lender's customary
disbursement procedures for construction loans.

     (e)  The Condemnation shall have occurred more than twelve (12) months
prior to the Maturity Date.

If any of these conditions shall not be satisfied, then Lender shall have the
right to use the condemnation proceeds to prepay the Loan in accordance with the
Note. If any condemnation proceeds shall remain after completion of the
restoration, repair and rebuilding of the Mortgaged Property, they shall be
disbursed to Borrower, or at Lender's discretion, used to prepay the Loan in
accordance with the Note.

                                      ARTICLE IV

                                DEFAULTS AND REMEDIES

     SECTION 4.1    EVENTS OF DEFAULT. An Event of Default, as defined in the
Loan Agreement, shall constitute an Event of Default hereunder.

     SECTION 4.2    REMEDIES. Upon the occurrence of an Event of Default
described in Sections 6.1(f), (g) or (h) of the Loan Agreement, all of the
Obligations shall be accelerated and become immediately due and payable without
notice or declaration to Borrower. Upon the occurrence of one or more other
Events of Default, all of the Obligations, at the option of Lender, shall be
accelerated and become immediately due and payable upon notice to Borrower. In
either event, the Obligations shall be due and payable without presentment,
demand or further notice of any kind. Lender shall have the right to proceed to
protect and enforce its rights by one or more of the following remedies:

     (a)  LENDER SHALL HAVE THE RIGHT TO BRING SUIT either for damages, for
specific performance of any agreement contained in any Loan Document, for the
foreclosure of this Mortgage, or for the enforcement of any other appropriate
legal or equitable remedy.

     (b)  LENDER SHALL HAVE THE RIGHT TO SELL THE MORTGAGED PROPERTY AT PUBLIC
AUCTION AND CONVEY THE SAME TO THE PURCHASER IN FEE SIMPLE, as provided by law,
Borrower to remain liable for any deficiency. Said sale may be as one tract or
otherwise, at the sole option of Lender. In the event of any sale of the
Mortgaged Property pursuant to any judgment or decree of any court or at public
auction or otherwise in connection with the enforcement of any of the terms of
this Mortgage, Lender, its successors or assigns, may become the purchaser, and
for the purpose of making settlement for or payment of the purchase price, shall
be entitled to deliver over and use the Note and any claims for interest accrued
and unpaid thereon, together with all other sums, with interest, advanced or 


                                          9

<PAGE>

secured hereby and unpaid hereunder, in order that there may be credited as paid
on the purchase price the total amount of the Obligations then due, including
principal and interest on the Note and all other sums, with interest, advanced
or secured hereby and unpaid hereunder or under any of the other Loan Documents.

     (c)  LENDER SHALL HAVE THE RIGHT TO OBTAIN THE APPOINTMENT OF A RECEIVER at
any time after the occurrence of an Event of Default. Lender may apply for the
appointment of a receiver to the district court for the county where the
Mortgaged Property or any part thereof is located, by an action separate from
any foreclosure of this Mortgage pursuant to Minnesota Statutes Chapter 580 or
pursuant to Minnesota Statutes Chapter 581, or as a part of the foreclosure
action under said Chapter 581 (it being agreed that the existence of a
foreclosure pursuant to said Chapter 580 or a foreclosure action pursuant to
said Chapter 581 is not a prerequisite to any action for a receiver hereunder).
Lender shall be entitled to the appointment of a receiver without regard to
waste, adequacy of the security or solvency of Borrower. The receiver, who shall
be an experienced property manager, shall collect (until the Obligations are
fully paid and satisfied and, in the case of a foreclosure sale, during the
entire redemption period) the Rents, and shall manage the Mortgaged Property,
execute Leases within or beyond the period of the receivership if approved by
the court and apply all rents, profits and other income collected by him in the
following order:

          (i)       to the payment of all reasonable fees of the receiver, if
any, approved by the court;

          (ii)      to the repayment of tenant security deposits, with interest
thereon, as required by Minnesota Statutes, Section 504.20;

          (iii)     to the payment when due of delinquent or current real estate
taxes or special assessments with respect to the Mortgaged Property, or the
periodic escrow for the payment of the same;

          (iv)      to the payment when due of premiums for insurance of the
type required by this Mortgage, or the periodic escrow for the payment of the
same;

          (v)       to the payment for the keeping of the covenants required of
a lessor or licensor pursuant to Minnesota Statutes, Section 504.18, subdivision
1;

          (vi)      to the payment of all expenses for normal maintenance of the
Mortgaged Property; and

          (vii)     the balance to Lender (a) if received prior to the
commencement of a foreclosure, to be applied to the Obligations, in such order
as Lender may elect and (b) if received after the commencement of a foreclosure,
to be applied to the amount required to be paid to effect a reinstatement prior
to foreclosure sale, or, after a foreclosure sale to any deficiency and
thereafter to the amount required to be paid to effect a redemption, all
pursuant to Minnesota Statutes, Sections 580.30, 580.23 and 581.10, with any
excess to be paid to Borrower.


                                          10

<PAGE>

Provided, that if this Mortgage is not reinstated nor the Mortgaged Property
redeemed as provided by said Sections 580.30, 580.23 or 581.10, the entire
amount paid to Lender pursuant hereto shall be the property of Lender together
with all or any part of the Mortgaged Property acquired through foreclosure.

     Lender shall have the right, at any time and without limitation, as
provided in Minnesota Statutes, Section 582.03, to advance money to the receiver
to pay any part or all of the items which the receiver should otherwise pay if
cash were available from the Mortgaged Property and sums so advanced, with
interest at the Default Rate set forth in the Note, shall be secured hereby, or
if advanced during the period of redemption shall be part of the sum required to
be paid to redeem from the sale.

     (d)  LENDER SHALL HAVE THE RIGHT TO COLLECT THE RENTS from the Mortgaged
Property and apply the same in the manner hereinbefore provided with respect to
a receiver. For that purpose, Lender may enter and take possession of the
Mortgaged Property and manage and operate the same and take any action which, in
Lender's judgment, is necessary or proper to collect the Rents and to conserve
the value of the Mortgaged Property. Lender may also take possession of, and for
these purposes use, any and all of the Personal Property. The expense (including
any receiver's fees, attorneys' fees, costs and agent's compensation) incurred
pursuant to the powers herein contained shall be secured by this Mortgage.
Lender shall not be liable to account to Borrower for any action taken pursuant
hereto other than to account for any Rents actually received by Lender.
Enforcement hereof shall not cause Lender to be deemed a mortgagee in possession
unless Lender elects in writing to be a mortgagee in possession.

     (e)  LENDER SHALL HAVE THE RIGHT TO ENTER AND TAKE POSSESSION of the
Mortgaged Property and manage and operate the same in conformity with all
applicable laws and take any action which, in Lender's judgment, is necessary or
proper to conserve the value of the Mortgaged Property.

     (f)  LENDER SHALL HAVE ALL OF THE RIGHTS AND REMEDIES PROVIDED IN THE
UNIFORM COMMERCIAL CODE including the right to proceed under the Uniform
Commercial Code provisions governing default as to any Personal Property
separately from the real estate included within the Mortgaged Property, or to
proceed as to all of the Mortgaged Property in accordance with its rights and
remedies in respect of said real estate. If Lender should elect to proceed
separately as to such Personal Property, Borrower agrees to make such Personal
Property available to Lender at a place or places acceptable to Lender, and if
any notification of intended disposition of any of such Personal Property is
required by law, such notification shall be deemed reasonably and properly given
if given at least ten (10) days before such disposition in the manner
hereinafter provided.

     (g)  LENDER SHALL HAVE THE RIGHT TO FILE PROOF OF CLAIM and other documents
as may be necessary or advisable in order to have its claims allowed in any
receivership, insolvency, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceedings affecting Borrower, its creditors or
its property, for the entire amount due and payable by Borrower in respect of
the Obligations at the date of the institution of such


                                          11

<PAGE>

proceedings, and for any additional amounts which may become due and payable by
Borrower after such date.

Each remedy herein specifically given shall be in addition to every other right
now or hereafter given or existing at law or in equity, and each and every right
may be exercised from time to time and as often and in such order as may be
deemed expedient by Lender and the exercise or the beginning of the exercise of
one right shall not be deemed a waiver of the right to exercise at the same time
or thereafter any other right. Lender shall have all rights and remedies
available under the law in effect now and/or at the time such rights and
remedies are sought to be enforced, whether or not they are available under the
law in effect on the date hereof.

     SECTION 4.3    EXPENSES OF EXERCISING RIGHTS POWERS AND REMEDIES. The
reasonable expenses (including any receiver's fees, attorneys' fees, appraisers'
fees, environmental engineers' and/or consultants' fees, costs incurred for
documentary and expert evidence, stenographers' charges, publication costs,
costs (which may be estimated as to items to be expended after entry of the
decree of foreclosure) of procuring all abstracts of title, continuations of
abstracts of title, title searches and examinations, title insurance policies
and commitments and extensions therefor, Torrens duplicate certificates of
title, UCC and chattel lien searches, and similar data and assurances with
respect to title as Lender may deem reasonably necessary either to prosecute any
foreclosure action or to evidence to bidders at any sale which may be had
pursuant to any foreclosure decree the true condition of the title to or the
value of the Mortgaged Property, and agent's compensation) incurred by Lender
after the occurrence of any Event of Default and/or in pursuing the rights,
powers and remedies contained in this Mortgage shall be immediately due and
payable by Borrower, with interest thereon from the date incurred at the Default
Rate set forth in the Note, and shall be added to the indebtedness secured by
this Mortgage.

     SECTION 4.4    RESTORATION OF POSITION. In case Lender shall have proceeded
to enforce any right under this Mortgage by foreclosure, sale, entry or
otherwise, and such proceedings shall have been discontinued or abandoned for
any reason or shall have been determined adversely, then, and in every such
case, Borrower and Lender shall be restored to their former positions and rights
hereunder with respect to the Mortgaged Property subject to the lien hereof.

     SECTION 4.5    MARSHALLING. Borrower, for itself and on behalf of all
persons, parties and entities which may claim under Borrower, hereby waives all
requirements of law relating to the marshalling of assets, if any, which would
be applicable in connection with the enforcement by Lender of its remedies for
an Event of Default hereunder, absent this waiver. Lender shall not be required
to sell or realize upon any portion of the Mortgaged Property before selling or
realizing upon any other portion thereof.

     SECTION 4.6    WAIVERS. No waiver of any provision hereof shall be implied
from the conduct of the parties. Any such waiver must be in writing and must be
signed by the party against which such waiver is sought to be enforced. The
waiver or release of any breach of the provisions set forth herein to be kept
and performed shall not be a waiver or release of any preceding or subsequent
breach of the same or any other provision. No receipt of partial payment after
acceleration of any of the Obligations shall waive the acceleration. No payment
by


                                          12

<PAGE>

Borrower or receipt by Lender of a lesser amount than the full amount secured
hereby shall be deemed to be other than on account of the sums due and payable
hereunder, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment be deemed an accord and satisfaction, and
Lender may accept any check or payment without prejudice to Lender's right to
recover the balance of such sums or to pursue any other remedy provided in this
Mortgage. The consent by Lender to any matter or event requiring such consent
shall not constitute a waiver of the necessity for such consent to any
subsequent matter or event.

     SECTION 4.7    LENDER'S RIGHT TO CURE DEFAULTS. If Borrower shall fail to
comply with any of the terms of the Loan Documents with respect to the procuring
of insurance, the payment of taxes, assessments and other charges, the keeping
of the Mortgaged Property in repair, or any other term contained herein or in
any of the other Loan Documents, Lender may make advances to perform the same
without releasing Borrower from any of the Obligations. Borrower agrees to repay
upon demand all sums so advanced and all sums expended by Lender in connection
with such performance, including without limitation attorneys' fees, with
interest at the Default Rate set forth in the Note from the dates such advances
are made, and all sums so advanced and/or expenses incurred, with interest,
shall be secured hereby, but no such advance and/or incurring of expense by
Lender, shall be deemed to relieve Borrower from any default hereunder or under
any of the other Loan Documents, or to release Borrower from any of the
Obligations.

     SECTION 4.8    SUITS AND PROCEEDINGS. Lender shall have the power and
authority, upon prior notice to Borrower, to institute and maintain any suits
and proceedings as Lender may deem advisable to (i) prevent any impairment of
the Mortgaged Property by any act which may be unlawful or by any violation of
this Mortgage, (ii) preserve or protect its interest in the Mortgaged Property,
or (iii) restrain the enforcement of or compliance with any legislation or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid, if, in the sole opinion of Lender, the enforcement of or compliance
with such enactment, rule or order might impair the security hereunder or be
prejudicial to Lender's interest.

    The Brooklyn Park Economic Development Authority (the "Authority"), for
value received, certifies that it is indebted and hereby promises to pay to
AVECOR Cardiovascular Inc. or registered assigns (the "Owner"), the principal
sum of $893,402 and to pay interest thereon at the rate of 9.50% per annum (the
"Stated Rate"), as and to the extent set forth herein. (NOTE: PAYMENT HEREUNDER
IS SUBJECT TO AND RESTRICTED BY SECTION 4.3(D) OF INDIVIDUAL DEVELOPMENT
AGREEMENT #5 BY AND BETWEEN THE AUTHORITY AND RYAN CONSTRUCTION COMPANY OF
MINNESOTA, INC. ("RYAN") DATED OCTOBER 4, 1996.)

    1.   PAYMENTS.  Principal and interest ("Payments") shall be paid semi-
annually on each February 1 and August 1, commencing August 1, 1998 and
continuing to and including February 1, 2005 ("Payment Dates") in the amounts
set forth in Attachment A hereto (the "Payment Schedule"), but only to the
extent of Available Tax Increment as hereinafter defined. Payments shall be
applied first to accrued interest, and then to unpaid principal.

    Payments are payable by mail to the address of the Owner or such other
address as the Owner may designate upon 30 days written notice to the Authority.
Payments on this Note are payable in any coin or currency of the United Sates of
America which, on the Payment Date, is legal tender for the payment of public
and private debts.

    2.   INTEREST.  Interest at the Stated Rate shall accrue on this Note's
initial principal amount of $893,402 (the "Initial Principal") commencing on the
Date of Original Issue set forth above. The interest that will accrue between

Principal on February 1, 1998 and the sum of $980,291 shall be the Principal
Amount of this Note. Interest shall accrue on the unpaid balance of the
Principal Amount at the Stated Rate from and after February 1, 1998, and shall

part of the semi-annual Payments provided in the Payment Schedule attached

<PAGE>

    3.   AVAILABLE TAX INCREMENT. Payments on this Note are payable solely from
"Available Tax Increment," which shall mean, on each Payment Date, 52.5% of the
Tax Increment generated in the preceding six (6) months with respect to
"Individual Development Property #5" and the "Individual lmprovements" thereon
and remitted to the Authority by Hennepin County not to exceed the total
scheduled Payment set forth in the Payment Schedule, all as such terms are
defined in the Individual Development Agreement #5, dated as of October 4, 1996
(the "Agreement") between the Authority and Ryan.

    Available Tax Increment shall not include any Tax Increment generated by
the Individual Development Property #5 if, as of any Payment Date, the Owner has
breached and failed to cure any term or condition of the Agreement.

    The Authority shall have no obligation to pay principal of and interest on
this Note on any Payment Date from any source other than Available Tax
lncrement, and the failure of the Authority to pay the entire amount of
principal or interest on this Note on any Payment Date as set forth in the
Payment Schedule shall not constitute a default hereunder as long as the
Authority pays principal and interest hereon to the extent of Available Tax
Increment. If on any Payment Date there is available to the Authority
insufficient Available Tax Increment to pay all amounts due on such date, the
amount of such deficiency shall be deferred and shall be paid, without interest
thereon, on the next Payment Date on which the Authority has available to it
Available Tax Increment in excess of the amount necessary to pay the amount due
on such Payment Date.  The Authority shall have no obligation to pay unpaid
balance of principal or accrued interest that may remain after the final Payment
due on February 1, 2005.

    4.   OPTIONAL PREPAYMENT. The principal sum and all accrued interest
payable under this Note is prepayable in whole or in part at any time by the
Authority without premium or penalty.

    5.   TERMINATION. At the Authority's option, this Note shall terminate and
the Authority's obligation to make any payments under this Note shall be
discharged upon the occurrence of an Event of Default on the part of the
Developer as defined in Section 9.1 of the Agreement, but only if the Event of
Default has not been cured in accordance with Section 9.2 of the Agreement.

    6.   NATURE OF OBLIGATION. This Note is an issue to aid in financing
certain qualified costs and administrative costs of a Project undertaken by the
Authority pursuant to Minnesota Statutes, Sections 469.124 through 469.134, and
is issued pursuant to an authorizing resolution (the "Resolution") duly adopted
by the Authority (the terms of which are incorporated herein), and pursuant to
and in full conformity with the Constitution and laws of the State of Minnesota,
including MINNESOTA STATUTES, Sections 469.174 to 469.179. This Note is a
limited obligation of the Authority which is payable solely from Available Tax
Increment pledged to the payment hereof under the Resolution. This Note and the
interest hereon shall not be deemed to constitute a general obligation of the
State of Minnesota or any political subdivision thereof, including, without
limitation, the Authority. Neither the State of Minnesota, nor any political
subdivision thereof shall be obligated to pay the principal of or interest on
this Note or other costs incident

hereto except out of Available Tax Increment, and neither the full faith and
credit nor the taxing power of the State of Minnesota or any political
subdivision thereof is pledged to the payment of the principal of or interest on
this Note or other costs incident hereto.

    EXCEPT AS TO THE OBLIGATION TO MAKE PAYMENTS FROM AVAILABLE TAX INCREMENT,
    THIS NOTE IS NOT A DEBT OF THE AUTHORITY, THE CITY OF BROOKLYN PARK (THE
    "CITY"), OR THE STATE OF MINNESOTA (THE "STATE"), AND NEITHER THE
    AUTHORITY, THE C1TY, THE STATE, NOR ANY POLITICAL SUBDIVISION THEREOF SHALL
    BE LIABLE ON THE NOTE, NOR SHALL THE NOTE BE PAYABLE OUT OF ANY FUNDS OR
    PROPERTIES OTHER THAN AVAILABLE TAX INCREMENT.

    7.   REGISTRATION AND TRANSFER.  This Note is issuable only as a fully
registered note without coupons. As provided in the Resolution, and subject to
certain limitations set forth therein, this Note is transferable upon the books
of the Authority kept for that purpose, at the principal office of the
Authority, by the Owner hereof in person or by such Owner's attorney duly
authorized in writing, upon surrender of this Note together with a written
instrument of transfer satisfactory to the Authority, duly executed by the
Owner. Upon such transfer or exchange and the payment by the Owner of any tax,
fee, or governmental charge required to be paid by the Authority with respect to
such transfer or exchange, there will be issued in the name of the transferee a
new Note of the same aggregate principal amount, bearing interest at the same
rate and maturing on the same dates.

    This Note shall not be transferred to any person other than an affiliate,
or other related entity, of the Owner unless the Authority has been provided
with an opinion of counsel from the transferor and an investment letter from the
transferee, in a form satisfactory to the Authority, establishing that such
transfer is exempt from registration and prospectus delivery requirements of
federal and applicable state securities laws.

    IT IS HEREBY CERTIFIED AND RECITED that all acts, conditions, and things
required by the Constitution and laws of the State of Minnesota to be done, to
exist, to happen, and to be performed in order to make this Note a valid and
binding limited obligation of the Authority according to its terms, have been
done, do exist, have happened, and have been performed in due form, time and

TO OUR SHAREHOLDERS:

     While the costs of litigating and settling a patent suit caused a loss for
1996, AVECOR Cardiovascular made tremendous progress on a number of fronts.
Sales increased 33% as the AFFINITY oxygenator continued to strengthen its
market position. International sales continued to increase, with further
investment and expansion in Europe. We submitted a 510(k) application to begin
marketing our innovative new blood pump. And we moved to a new headquarters
building that allows us to combine all of our Minneapolis operations under one
roof for the first time.

     SALES TOP $44 MILLION  Sales expanded to $44.4 million, up 33% from 1995,
led by the AFFINITY oxygenator line which continued to strengthen its position
with a 39% increase over 1995. Sales of custom tubing packs more than doubled to
$7.4 million. The older silicone membrane oxygenator line continued its decline
with a 4% decrease for the year, while sales of MYOtherm cardioplegia systems
gained 6%.

     Gross margins declined to 41.5% from 45.5% in 1995, mainly as the result of
the sharply increased sales of lower-margin custom tubing packs. Competitive
pricing and the continued trend toward group buying and the associated quantity
discounts also adversely affected margins. In the third quarter, we initiated a
number of changes to improve margins. These involve selective price increases,
sales incentives tied to margin improvement, and further efforts to reduce
manufacturing costs. The positive effect of these actions began to show in the
fourth quarter of 1996, and we expect additional margin improvement during 1997.

     We continued to emphasize investment in research and development in order
to expand and improve our product line. R&D spending rose to $3.7 million in
1996 as the AFFINITY blood pump was readied for market. Selling, general and
administrative expenses also grew, mainly reflecting a one-third expansion of
our domestic sales force.

     The Company recorded a loss for the year primarily as the result of the
$4.2 million cost of litigating and settling a patent suit with COBE
Laboratories. We also recorded a non-recurring charge of $474,000 in the fourth
quarter to reflect the costs related to the relocation of our headquarters,
lease abandonment costs and severance-related expenses.
After these charges, the loss for the year was $567,000, equal to 7 cents a
share. We earned 45 cents per share in 1995.

CONTINUED INTERNATIONAL GROWTH  International sales continue to be an important
part of our growth strategy. In 1996, international sales totalled over $18
million and continued the compound growth rate of approximately 40% annually
realized over the last three years.

     We also continued to invest in our French subsidiary to further develop
product sales on the European continent.

SALES OF AFFINITY PUMP EXPECTED TO BEGIN IN 1997  We anticipate receiving
marketing clearance for the new AFFINITY blood pump from the U.S. Food and Drug
Administration (FDA) in the first half of 1997. European clinical trials, aimed
at demonstrating the superior characteristics of the new pump, began in the
first quarter of 1997 at multiple sites.

     The new pump is undoubtedly our most significant product since we
introduced the AFFINITY oxygenator in 1993. We believe its innovative design
will make this pump safer and more cost-effective than centrifugal pumps, and
that it also will offer significant safety advantages over roller pumps
currently used in heart/lung bypass surgery. Because the AFFINITY pump cannot be
over-pressurized, won't drain the blood reservoir and has superior


                                        2
<PAGE>


blood-handling characteristics, we expect that it will be well-received by the
market. Like our other products, it is designed to be easy to set up and prime.

     The AFFINITY oxygenator continued to build market share in 1996. Its
powerful performance, superior operating characteristics and competitive price
continue to win over new users in the medical community.

     We expect to file three new products with the FDA in 1997. First is an
improved MYOtherm cardioplegia system, scheduled for submission late in the
first quarter. In addition to high performance and ease of use -- hallmarks of
all AVECOR products -- the new cardioplegia system will be simpler to
manufacture, which should help improve margins on this segment of the business.
Other submissions scheduled in 1997 involve proprietary system coatings to
improve blood handling and new oxygen saturation/hemocrit technology.

COBE SUIT SETTLED  The COBE patent suit was settled in July of 1996 for an
amount that approximated the cost of carrying the suit through to trial. Terms
of the settlement, which contains cross-licensing provisions, call for a net
payment by AVECOR of $2.2 million, for which AVECOR received a paid-up license
of three COBE patents for oxygenators and related devices.

     The agreement was entered into without admission or liability or
infringement by either party. Conclusion of this litigation has allowed
management to focus its entire attention on the Company's growth and
profitability.

NEW FACILITY COMPLETED  The Company has completed its move to a new headquarters
facility in suburban Minneapolis. This consolidates all laboratory, engineering,
office, manufacturing and warehousing activities in a single location, which is
expected to result in significantly improved efficiency. These functions had
previously occupied four different locations.

     The Company owns the new building, which occupies 100,000 square feet on a
12-acre site in suburban Brooklyn Park. Laboratories, clean room facilities and
a customer education and training center at the new site incorporate state-of-
the-art technology. We also have room for expansion, should that become
necessary in the future.

     The move to the new building was accomplished in stages with minimum
disruption of our activities. All departments are now operating at the new
location.

1997 OUTLOOK  All of us at AVECOR are excited to be in our new building, and we
are looking forward to what we expect will be a very successful introduction of
the AFFINITY pump in 1997. We fully expect to realize a healthy profit in 1997
from our larger product line and further global expansion, and we will continue
our research into new products that improve patient benefits while lowering
costs.


Sincerely,

/s/ Anthony Badolato

PRODUCT REVIEW

The products of AVECOR Cardiovascular Inc. are used primarily in heart/lung
bypass surgery and for long-term respiratory support. The annual worldwide
market for specialty medical devices used in bypass surgery is estimated at $800
million, of which about $600 million is attributable to
disposable products.

     The Company's current products include:

     [PHOTO]

     THE AFFINITY OXYGENATOR, STILL THE CENTERPIECE OF AVECOR'S PRODUCT LINE,
     CONTINUES TO INCREASE ITS MARKET SHARE.

     THE AFFINITY-TM- OXYGENATOR.  Introduced internationally in mid-1993 and to
the U.S. market in 1994, the AFFINITY is a microporous, hollow fiber membrane
oxygenator. During a bypass procedure, the oxygenator takes the place of the
patient's lungs, removing carbon dioxide and adding oxygen to the blood. The
AFFINITY is a state-of-the-art device that studies have shown to be one of the
most efficient oxygenators on the market. It combines high gas transfer with low
pressure drop. Its compact size provides low priming volumes; its clear
polycarbonate case permits high visibility of all phases of the unit's
operation. The AFFINITY oxygenator continued to increase its worldwide market
share in 1996, and at year-end was estimated to be the third best-selling
oxygenator in the U.S., with a market share of approximately 16%. This reflects
growing awareness of its superior performance and ease of use.

   SOLID SILICONE MEMBRANE OXYGENATORS.  The Company markets a complete line of
these oxygenators in several models and sizes. This technology permits extended
use of the oxygenator for certain applications without the deterioration of
performance that microporous membrane oxygenators may experience. This is
particularly important for procedures that entail long-term support.

     AFFINITY-TM- BLOOD PUMP.  The AFFINITY blood pump incorporates an
innovative design that makes it safer and more cost-effective than the
centrifugal pumps that are widely used in heart/lung bypass surgery today. It
also offers significant safety advantages over roller pumps. The Company will
begin marketing the pump in the U.S. following clearance from the FDA, which is
anticipated in the first half of 1997. European clinical trials began at
multiple sites in the first quarter of 1997.

     BLOOD RESERVOIRS.  The Company produces a hardshell cardiotomy reservoir
and venous reservoir bags. These devices are used to filter and store blood
during bypass surgery. The Company began marketing two new reservoirs in mid-
1994.

     MYOTHERM-TM- CARDIOPLEGIA SYSTEM.  This system is used to infuse specially
formulated solutions, which often include oxygenated blood, directly into the
patient's coronary arteries while the heart is stopped during bypass surgery.
In addition to delivering nutrients to the heart, these


                                        4
<PAGE>


solutions are also used to arrest the heart and maintain prescribed
temperatures. A new version of the MYOtherm unit, the MYOtherm XP, designed for
higher performance and improved manufacturing efficiences, is scheduled for
submission to the FDA late in the first quarter of 1997.

     ECMO System. The Company produces a system for extracorporeal membrane
oxygenation (ECMO), which is the long-term cardiopulmonary support of premature
infants, newborns and other patients with life-threatening respiratory
disorders. The system includes reservoir bags, heat exchangers and a membrane
oxygenator.

     THE NEW AFFINITY BLOOD PUMP, CURRENTLY AWAITING MARKETING CLEARANCE FROM
     THE FDA, IS SHOWN HERE IN A TYPICAL INSTALLATION WITH AVECOR'S HARDSHELL
     CARDIOTOMY VENOUS RESERVOIR AND THE AFFINITY OXYGENATOR. THE PUMP'S CONTROL
     CONSOLE IS ON THE RIGHT.

     SIGNATURE-TM- CUSTOM TUBING PACKS.  All or some of the devices used in a
heart/lung bypass procedure are sometimes pre-connected and sold in a custom
tubing pack. The components to be included in the pack and the exact way they
are arranged and connected are determined by the specifications provided by our
customer, the perfusionist. The Company has developed computer software that
allows it to design custom tubing packs according to these individual
specifications and to quote prices within hours of a customer request. AVECOR
began assembling and selling custom tubing packs in Europe in 1992 and in the
United States in mid-1993.

     AFFINITY-TM- ARTERIAL FILTER.  The Company introduced this product for
evaluation by customers late in 1995, with full release worldwide in the first
quarter of 1996. The AFFINITY filter is the final safety component in the
circuit of specialized medical devices used in heart/lung by-pass surgery,
ensuring that the oxygenated blood is free of air or particulate emboli before
reentering the patient's body. The filter offers low-volume priming, high
visibility, excellent air handling and excellent hemodynamics. The Company has
previously sold filters from other manufacturers as part of its custom tubing
packs.

     ONCOURSE-TM- CONTINUOUS QUALITY CONTROL (CQI) MANAGER.  This Windows-based
software program was introduced in late 1995. OnCourse CQI Manager guides
perfusionists through the necessary steps in establishing a CQI program. In
addition, it generates a variety of useful reports for perfusionists, including
the annual American Board of Cardiovascular Perfusion clinical activity report
and several custom reports such as Non-Compliance, Standard of Perfusion and
equipment preventative maintenance. This software is currently offered to AVECOR
customers who make a major commitment to AVECOR products -- another important
product line differentiation for AVECOR in the marketplace.

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


The following discussion of the Company's results of operations and financial
condition should be read in conjunction with the Company's Consolidated
Financial Statements and Notes thereto.

OVERVIEW
AVECOR Cardiovascular Inc. (the "Company") designs, develops, manufactures and
markets specialty disposable medical devices for heart/lung bypass surgery and
long-term respiratory support. The Company was incorporated on December 13,
1990, and in June 1991, acquired the business and assets and assumed certain
liabilities of the surgical division of SCIMED Life Systems, Inc. (the
"Predecessor Business"). On December 1, 1992, the Company exchanged 160,000
shares of its Common Stock for all of the outstanding shares of AVECOR
Cardiovascular Ltd. (formerly Cardio Med Ltd.) pursuant to which AVECOR
Cardiovascular Ltd. became a wholly-owned subsidiary of the Company. AVECOR
Cardiovascular Ltd. had formerly been a distributor for the Company in the
United Kingdom. In October 1995, the Company opened a sales office in France
which is organized as a wholly-owned subsidiary of AVECOR Cardiovascular Ltd.

The assets acquired by the Company from the Predecessor Business included the
Company's line of solid silicone membrane oxygenators. Since that time, the
Company has been successful in developing and obtaining marketing clearance for
a number of its proprietary products, with the goal of developing and marketing
a more complete line of proprietary products used in the heart/lung bypass
circuit. The Company began marketing its MYOtherm cardioplegia delivery system
in October 1991, and began marketing its Signature custom tubing packs in July
1993 following receipt of marketing clearance from the U.S. Food and Drug
Administration (the "FDA"). The Company began marketing its Affinity oxygenator
internationally in July 1993 and in the United States in February 1994,
following receipt of marketing clearance from the FDA in November 1993. The
Company received marketing clearance from the FDA to market its Affinity blood
reservoirs and Affinity arterial filter in July 1994 and October 1995,
respectively. In connection with the Company's continuing efforts to offer a
more complete line of proprietary heart/lung bypass circuit products, the
Company has developed a new blood pump, for which a 510(k) pre-market
notification was filed with the FDA in
September 1996.

RESULTS OF OPERATIONS
COMPARISON OF THE YEAR ENDED DECEMBER 31, 1996
WITH THE YEAR ENDED DECEMBER 31, 1995

  NET SALES. Net sales increased 33% to $44,401,000 for 1996 from $33,340,000
for 1995. This increase was principally the result of a higher volume of product
shipments of the Company's Affinity product line and Signature custom tubing
packs, which accounted for approximately 65% and 36% of the overall increase in
net sales, respectively. Overall, average prices associated with 1996 product
shipments declined slightly from that of 1995 in response to competitive pricing
in the market place. Selective price increases were implemented in the last half
of 1996. The favorable impact of increased net sales of these product lines was
partially offset by a decrease of $276,000 in net sales of the Company's older
solid silicone membrane oxygenator product line. The Company believes that the
availability of the Affinity oxygenator continues to be the primary contributor
to the decline in net sales of the Company's solid silicone membrane oxygenator
line, as certain customers changed their oxygenator of preference from the
Company's solid silicone membrane oxygenator to the Affinity oxygenator. The
Company continues to anticipate declining shipments of products in the solid
silicone membrane oxygenator line.

  Over the past two years, one of the Company's competitors has purchased three
companies that provide contract perfusion services to hospitals. The Company
believes that such control, as well as any future acquisitions of contract
perfusion groups by its competitors, are likely to have a negative impact on the
Company's ability to market its products to perfusionists controlled by
competitors or to hospitals or other medical providers that contract with
competitor-controlled groups for perfusion services, and could have a material
adverse effect on the Company's business, financial condition and results of
operations. Any effect of such control or future acquisitions is subject to the
degree of control exerted by the Company's competitors with respect to
purchasing decisions made by controlled groups of perfusionists, the extent of
future acquisitions of contract perfusion groups by the Company's competitors,
the breadth of the Company's product offerings relative to those of competitors
controlling contract perfusion groups, and the degree to which the Company's
research and development and marketing efforts result in the successful
commercialization of products with enhanced or superior performance
characteristics. For 1996, the Company estimates that sales to contract
perfusion groups controlled by one of the Company's competitors were
approximately $1,850,000, representing an increase of approximately $350,000
over 1995. However, the acquisitions of these contract perfusion groups occurred
in the first half of 1996 during which the Company sold about $1,100,000 to
these groups compared to approximately $750,000 in the second half of 1996.

  Sales to customers located outside of the United States were approximately
41% of consolidated net sales for 1996 compared to 42% for 1995.


                                        6
<PAGE>


     COST OF SALES/GROSS PROFIT. Cost of sales as a percentage of net sales
increased to 58.5% for 1996 from 54.5% for 1995. The cost of sales percentage
for 1996 was unfavorably impacted by significant increases in sales of the
Company's lower-margin Signature custom tubing pack line, as well as competitive
pricing pressures in the marketplace. The mix of products sold in any period
will influence the cost of sales and gross profit for the period.

     Higher production volumes continued to improve Affinity oxygenator product
costs, although, these improvements were offset, primarily by an ongoing
decrease in average selling prices due to the Company being in a competitive
pricing environment. Also, optimal volume-related manufacturing efficiencies
were not achieved throughout 1996 for production of the Company's Affinity
arterial filter. Production of the Affinity arterial filter began on or about
December 31, 1995.

     The Company's future gross profit margin percentages will be influenced by
the ongoing pressures of the competitive pricing environment, changes in the
sales mix, new product introductions and the extent of further manufacturing
efficiencies, if any. Given the uncertainty associated with new product
introductions, the ultimate realization of any such manufacturing efficiencies
and the continuing price pressures characteristic in the Company's markets, the
Company cannot be certain if its gross profit margin will be maintained, improve
or decline.

     SELLING, GENERAL AND ADMINISTRATIVE AND LITIGATION EXPENSE. Selling,
general and administrative expenses increased 36% to $11,885,000 for 1996 from
$8,727,000 for 1995. This increase is attributed to costs associated with the
continuing development of a direct sales force in certain of the Company's
territories formerly served by distributors and independent sales
representatives and the overall increase in support needed to achieve the
Company's sales levels. In connection with the Company's development of a direct
sales force, in October 1995, the Company opened a sales office in France from
which it fields a direct sales force to serve the French market. The Company
recorded non-recurring charges in the fourth quarter of 1996 associated with
relocation and lease abandonment expenses in connection with the consolidation
of the Company's U.S. operations from four leased facilities into one owned
property and the addition and subsequent resignation of a Chief Operating
Officer. As a percent of sales, selling, general and administrative expenses
increased to 26.8% for 1996 from 26.2% for 1995.

     Management anticipates that selling, general and administrative expenses
for the year ended December 31, 1997 will be higher than the year ended December
31, 1996 and will approximate 1996 as a percentage of sales dollars. This
forward-looking statement will be influenced by revenue increases achieved by
the Company, its ability to attract and retain qualified sales personnel as the
Company continues to develop its direct sales force, and the timing and extent
of promotional activities associated with new product introductions, if any.

     On July 17, 1996, the Company reached an agreement with COBE Laboratories
Inc. (COBE) to settle COBE's patent suit against the Company. The terms of the
settlement with COBE provide for the Company to make net payments totaling
$2,200,000, of which a net $1,100,000 was paid in August 1996. The remaining
amount is payable on or about August 6, 1997, subject to COBE's active
enforcement of its claimed patent rights with respect to other manufacturers.
The Company recorded settlement costs and professional expenses of approximately
$4,205,000 in 1996, in connection with the COBE suit, compared to $170,000 in
1995. See Consolidated Financial Statements -- Note 10 "Patent Matters."

     RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
increased 32% to $3,651,000 for 1996 from $2,773,000 for 1995. This increased
research and development spending is a result of the Company's ongoing efforts
to pursue a number of potential product opportunities, including a new blood
pump for which the Company submitted a 510(k) application with the FDA late in
September 1996. There can be no assurance that the appropriate marketing
clearance from the FDA will be received on a timely basis regarding this
product, if at all, or, if received, that this device will become commercially
successful.

     The Company anticipates that research and development expenses for 1997
will increase approximately 20% over 1996 levels, as the Company moves to expand
and improve its proprietary line of disposable medical devices. This forward-
looking projection is dependent upon the extent and timing of new product
development and the impact of the regulatory process in obtaining marketing
clearance for new products, including the new blood pump. The need or desire to
modify the Company's existing products could also influence the level of
research and development expenses. In addition to the aforementioned blood pump,
the Company is developing an improved MYOtherm cardioplegia system, scheduled
for FDA submission late in the first quarter of 1997; proprietary systems
coatings that will improve blood handling, scheduled for a mid-year 1997 FDA
submission; and new oxygen saturation/ hematocrit technology that is expected to
be submitted to the FDA late in the third quarter of 1997. There can be no
assurance, however, that the Company's research and development efforts will
result in regulatory submissions to the FDA as set forth above, if at all, or
will result in any commercially successful products. The forward-looking
statements regarding anticipated regulatory submissions contained in this
paragraph will be impacted by the results of the Company's development efforts,
the availability of any required clinical data, any changes in the regulatory
scheme for such products, and the Company's assessment of the cost and
anticipated benefit of such submissions.

     INTEREST INCOME. Interest income increased to $725,000 for 1996 from
$586,000 for 1995. Interest income during 1996 and 1995 was earned primarily
from the investment of the remaining net proceeds from the Company's June


                                        7
<PAGE>


1995 stock offering. At December 31, 1996, the majority of these remaining net
proceeds were invested with two investment portfolio managers who invested in
U.S. government securities, agency paper, money markets, commercial paper and
corporate obligations.

     INCOME TAX PROVISION. For 1996, a tax benefit of $34,000 was recorded as
compared to a tax provision of $780,000 for 1995. The 1996 effective tax rate
differs from the normal statutory tax rate primarily due to losses incurred by
the Company's French subsidiary for which no tax benefit has been recognized
because of uncertainty of realization. The 1995 tax provision reflects an
effective rate which benefited from use of previously generated net operating
loss carryforwards and research and experimentation credits.

     NET INCOME (LOSS). Net loss was $567,000 or $.07 per share for 1996
compared to net income of $3,296,000 or $.45 per share for 1995. The 1996 loss
is primarily due to litigation and settlement expense incurred during 1996 in
connection with the COBE lawsuit, which resulted in a charge to operations of
$4,205,000.

COMPARISON OF THE YEAR ENDED DECEMBER 31, 1995
WITH THE YEAR ENDED DECEMBER 31, 1994

     NET SALES. Net sales increased 55% to $33,340,000 for 1995 from $21,486,000
for 1994. This increase was principally the result of a higher volume of product
shipments of the Company's Affinity product line and Signature custom tubing
packs.

     Sales from the Affinity product line accounted for approximately 88% of the
overall increase in net sales. The Company began U.S. marketing of the Affinity
oxygenator in late February 1994 and the Affinity blood reservoirs in July 1994.
The favorable impact of increased net sales of these product lines was partially
offset by a decrease of $842,000 in net sales of the Company's older solid
silicone membrane oxygenator product line.

     COST OF SALES/GROSS PROFIT. Cost of sales as a percentage of net sales
decreased to 54.5% for 1995 from 58.4% for 1994. The cost of sales percentage
for the year ended December 31, 1995 was favorably impacted principally by a
significant change in product mix in 1995, as a result of substantial sales
increases in the Affinity product line, and by higher overall production volumes
as a result of increases in net sales. This decrease in cost of sales as a
percentage of net sales was partially offset by a decrease in average selling
prices in the Affinity product line.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 31% to $8,897,000 for the year ended December
31, 1995 from $6,779,000 for the year ended December 31, 1994. This increase is
attributed to an overall increase in the Company's activity level and costs
associated with the continuing development of a direct sales force in connection
with sales of the Affinity product line in the United States. In connection with
the Company's development of a direct sales force the Company also opened a
sales office in France from which it now fields a direct sales force to serve
the French market. Also, the Company expensed $170,000 during 1995 in connection
with the COBE lawsuit.

     RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
increased 20% to $2,773,000 for the year ended December 31, 1995 from $2,309,000
for the year ended December 31, 1994. Beginning in the second quarter of 1994,
the Company increased research and development spending to pursue a number of
potential product opportunities.

     INTEREST INCOME. Interest income increased to $586,000 for the year ended
December 31, 1995 from $143,000 for the year ended December 31, 1994. Interest
income in 1995 increased primarily because of earnings on the Company's
investment of the net proceeds from its June 1995 stock offering. As of December
31, 1995 the proceeds were invested in bank certificates of deposit, commercial
paper and a daily money market fund.

     INCOME TAX PROVISION. For the year ended December 31, 1995, a provision for
income taxes of $780,000 was recorded. At December 31, 1994 the Company
maintained a full valuation allowance for its net operating loss carryforwards
due to a limited history of operating profits. All net operating loss
carryforwards were utilized in 1995 and the valuation allowance was accordingly
reversed. The Company recorded a minimal provision for income taxes for the year
ended December 31, 1994 which consisted primarily of foreign taxes payable.

     NET INCOME (LOSS). Net income was $3,296,000 or $.45 per share for the year
ended December 31, 1995, compared to a net loss of $39,000 or ($.01) per share
for the year ended December 31, 1994.

LIQUIDITY AND CAPITAL RESOURCES
For 1996, the Company used $2,470,000 in operating activities compared to
providing $1,481,000 from operating activities in 1995. The net change of
$3,951,000 is primarily the result of paying about $3,100,000 in litigation and
settlement expenses, along with increasing levels of accounts receivable and
inventory resulting from increasing revenues. These operating uses of cash were
offset by increased accrued expenses in 1996. The Company believes that its
existing cash and cash equivalents and short-term investments, as well as
anticipated cash generated from operations, will be sufficient to satisfy the
Company's cash requirements for the foreseeable future.

  Cash expenditures for capital additions totaled $2,629,000 in 1996 compared
to $1,146,000 in 1995. These expenditures were primarily related to the addition
of equipment, molds and tooling necessary to further the production of the
Affinity oxygenator, related blood reservoirs and arterial filter, and include
$332,000 related to the equipment, molds and tooling for the anticipated
production of the Company's new blood pump. The 1996 cash expenditures include
capital additions related to the Company's new facility.


                                        8

  Leases for the Company's U.S. manufacturing, research and development and
administrative facilities expired on December 31, 1996. In January 1997, the
Company consolidated its four separate facilities into a newly constructed
facility, which the Company has purchased. The cost of this facility was
approximately $8,600,000, plus approximately $1,050,000 for the purchase of
furniture, fixtures and manufacturing equipment for the facility. To finance the
$9,650,000 total cost of the project, the Company entered into a $5,167,000 bank
note payable agreement in January 1997 and, in addition, will fund out of
corporate funds $4,483,000, of which approximately $650,000 was paid by the
Company during 1996. Closing occurred on January 30, 1997.

     The note payable agreement bears interest at 8.11% and requires monthly
principal payments of $21,531, plus interest, through January 2002 with the
remaining principal and interest due February 2002. The note payable is
collateralized by the new corporate headquarters and manufacturing facility and,
among other things, requires the Company to meet certain ratios related to
leverage, debt service and cash flow. Additionally, the bank note payable
agreement prohibits the Company from distributing dividends to its shareholders.

     At December 31, 1996, the Company had cash and short term investments of
$4,450,000 restricted for payment of the new corporate headquarters and
manufacturing facility.

     The Company anticipates that depreciation expense resulting from the new
facility should approximate the Company's facilities rental expense for 1996,
thus not significantly impacting 1997 cost of goods sold, selling, general and
administrative expense or research and development costs. Annual interest income
is expected to be reduced by approximately $250,000 as a result of this
transaction and an estimated $400,000 of interest expense is expected to be
added in 1997. The Company estimates that the overall 1997 after-tax impact of
constructing and financing associated with the new facility will be
approximately $.01 per share each quarter.

     The Company's capital expenditures for 1997 are expected to be
approximately $2,700,000, excluding construction costs related to the new
facility. This estimate includes additional equipment, molds and tooling for the
new blood pump, an improved MYOtherm cardioplegia system and new oxygen
saturation/hematocrit technology.

     The foregoing forward-looking statements relating to the amount of capital
expenditures, ultimate cash usage and future income statement impact are
dependent on the progress of the Company's product development efforts and the
timing of the receipt of FDA marketing clearance for any future products.

     In 1996, net cash proceeds of approximately $529,000 were generated from
exercises of the Company's stock warrants. At December 31, 1996, the majority of
these proceeds, along with a significant portion of the net proceeds from the
Company's offering of common stock in June 1995, remained in unrestricted cash
and cash equivalents and short-term investments and will be used for general
corporate purposes, including research and development, working capital and
possible acquisitions.

     As discussed above under "Results of Operations -- Selling, General and
Administrative and Litigation Expense", on July 17, 1996, the Company reached an
agreement with COBE to settle COBE's patent suit against the Company. The terms
of the settlement provide for the Company to make net payments totaling
$2,200,000, of which $1,100,000 was paid in August 1996. The remaining amount is
payable on or about August 6, 1997, subject to COBE's active enforcement of its
claimed patent rights with respect to other manufacturers. See Consolidated
Financial Statements -- Note 10 "Patent Matters."

FOREIGN CURRENCY TRANSACTIONS
Transactions by the Company's international subsidiaries are negotiated,
invoiced and paid in various foreign currencies, primarily pounds sterling and
U.S. dollars. Accordingly, the Company is currently subject to risks associated
with fluctuations in exchange rates between the various currencies.

     Substantially all of the Company's other international transactions are
denominated in U.S. dollars. Fluctuations in currency exchange rates in other
countries may therefore reduce the demand for the Company's products by
increasing the price of the Company's products in the currency of the countries
in which the products are sold.

NEW ACCOUNTING STANDARD
In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
(SFAS 123). The Company has elected to continue following the guidance of
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees, for measurement and recognition of stock-based transactions with
employees. The Company has adopted the disclosure provisions of SFAS 123 in
1996. See Consolidated Financial Statements -- Note 5 "Shareholders' Equity."

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS           AVECOR Cardiovascular Inc.



1. BUSINESS DESCRIPTION AND SIGNIFICANT
ACCOUNTING POLICIES:

BUSINESS DESCRIPTION: AVECOR Cardiovascular Inc.
(the "Company") was incorporated on December 13, 1990. The Company designs,
develops, manufactures and markets specialty disposable medical devices for
heart/lung bypass surgery and long-term respiratory support.

     PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include
the accounts of AVECOR Cardiovascular Inc. and its wholly owned subsidiaries,
AVECOR Cardiovascular Ltd. and AVECOR Foreign Sales Corporation, after
elimination of all significant intercompany transactions and accounts.

     CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS: For financial
reporting purposes, the Company considers all highly liquid investments
purchased with an original maturity of three months or less to be cash
equivalents. The Company's cash and cash equivalent balances are concentrated
primarily with two investment managers, the majority of which is invested in
daily money market funds.

     Short-term investments consist of bank certificates of deposit, U.S.
government securities, agency paper, commercial paper and other corporate
obligations, and money market instruments and are classified as short-term in
the balance sheet based on their maturity date. All of the Company's short-term
investments mature in 1997 and are considered by management to be "available for
sale."
At December 31, 1996, the estimated fair value of the short-term investments
approximated their cost. Unrealized gains and losses were not significant.

     At December 31, 1996, certain of these cash and cash equivalents and short-
term investments totaling $4,450,000 were restricted as to their use (see Note
6).

     CONCENTRATIONS OF CREDIT RISK: The Company's accounts receivable are
primarily due from independent distributors and hospitals located primarily in
the U.S. and Western Europe. Although the Company does not require collateral
from its customers, concentrations of credit risk in the U.S. are somewhat
mitigated by a large number of geographically dispersed customers. The Company
has a significant amount of trade receivables from distributors outside of the
U.S., primarily in Western Europe. The Company does not presently anticipate
credit risk associated with foreign trade receivables, although collection could
be impacted by the underlying economies of the respective countries.

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

     PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment are carried at
cost less accumulated depreciation and amortization. Depreciation and
amortization are recorded using the straight-line method over estimated useful
asset lives of generally five years or less (shorter of asset life or lease term
for improvements). The cost of molds, tooling and dies is capitalized and
depreciated generally over periods of three to five years using straight-line or
units of production methods.

     Maintenance, repairs and minor improvements are charged to expense as
incurred while major betterments and renewals are capitalized. When assets are
sold or retired, the cost and related accumulated depreciation and amortization
are removed from the accounts and the resulting gain or loss is included in
operations.

     REVENUE RECOGNITION: The Company recognizes sales upon product shipment.

     RESEARCH AND DEVELOPMENT: Research and development costs are expensed as
incurred.

     INCOME TAXES: The Company accounts for income taxes using the liability
method. The liability method provides that deferred tax assets and liabilities
are recorded based on the differences between the tax bases of assets and
liabilities and their carrying amounts for financial reporting purposes
("temporary differences") using enacted tax rates in effect in the years in
which the differences are expected to reverse. Temporary differences relate
primarily to the allowance for doubtful accounts, obsolete inventory allowances,
depreciation, and accruals for vacation, product liability and warranty costs.

     NET INCOME (LOSS) PER SHARE: Net income (loss) per common and common
equivalent share has been computed by dividing net income (loss) by the weighted
average number of common and common equivalent shares outstanding. Common
equivalent shares relate to stock options and stock warrants when their effect
is not antidilutive. The difference between primary and fully diluted earnings
per share was not significant in any year presented.

     FOREIGN CURRENCY TRANSLATION: All assets and liabilities of the Company's
international subsidiaries are translated to U.S. dollars at year-end exchange
rates, while elements of the statement of operations are translated at average
exchange rates in effect during the year. Translation adjustments arising from
the use of differing exchange rates are included in cumulative translation
adjustments in shareholders' equity.

     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


                                       14
<PAGE>


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. The most significant areas which require the use of
management's estimates relate to the determination of the allowances for
doubtful accounts receivable and obsolete inventory and the need for a valuation
allowance on deferred tax assets.

3. SUPPLEMENTAL CASH FLOW INFORMATION:

At December 31, 1996, the Company had accounts
payable of $387,000 relating to purchases of property, plant and equipment.

4. DEFERRED GRANT:

During 1996 and 1994, the Company received grants from the Scottish Government
to fund improvements for the Company's Scotland facility. Pursuant to terms of
the grant, the Company must satisfy certain benchmarks in order to retain the
funds received. Accordingly, funds received are reported as a "deferred grant"
on the Company's balance sheet pending periodic satisfaction of the benchmarks.
The Company expects to satisfy these benchmarks.


5. SHAREHOLDERS' EQUITY:

SERIAL PREFERRED STOCK: The Company's Restated Articles of Incorporation provide
for 2,000,000 shares of preferred stock, par value $.01 per share, issuable in
series ("Serial Preferred Stock"). The Board of Directors is empowered to
authorize the issuance and establish the terms of any shares of the Serial
Preferred Stock without shareholder approval. In 1996, the Board of Directors
authorized 200,000 shares for issuance as Series A Junior Preferred Stock under
the Company's Shareholder Rights Plan.

STOCK INCENTIVE PLAN: The Company's 1991 Stock Incentive Plan ("Plan") provides
for granting to eligible employees and certain other individuals nonqualified
and incentive options. The Company has reserved 1,050,000 shares of common stock
for issuance under the Plan. Options granted under the Plan are generally
exercisable beginning one year from the date of grant in cumulative yearly
amounts of 25% of the shares under option and expire, if not exercised, five
years after the date of grant.

     Pursuant to the terms of the Plan, optionees may use cash, tender
previously owned shares, or be credited for a portion of the shares exercised to
reimburse the Company for the cost of excercising the options and the taxes due
on the recognized gain. The shares tendered from the optionee or credited at
time of exercise are at the fair market value of the stock on the transaction
date. In 1996, 19,000 common shares valued at $278,000 and, in 1995, 33,000
shares valued at $486,000 were credited the optionees at the exercise date to
satisfy such obligations. No common shares were credited to optionees to satisfy
such obligations in 1994.

     Upon the occurrence of a change of control (as defined), all outstanding
options become immediately exercisable in full and all restrictions with respect
to outstanding restricted stock awards immediately lapse.

     The Plan also provides for stock bonuses and awards of restricted shares of
the Company's common stock to eligible recipients. Restricted shares awarded may
not be sold, assigned, or otherwise transferred by the recipient until the
shares awarded become free of restrictions on transferability. All shares still
subject to restrictions will be forfeited and returned to the Plan if
affiliation with the Company terminates. Plan administrators may waive or
accelerate the lapsing of restrictions.

     During the year ended December 31, 1994, $11,000 was charged to
compensation expense representing the quoted market value of 1,200 common shares
awarded to employees as stock bonuses. There were no stock bonuses issued under
the Plan for the years ended December 31, 1996 and 1995. No restricted shares
were issued under the Plan for the years ended December 31, 1996, 1995 and 1994.

     1995 NON-EMPLOYEE DIRECTOR PLAN: In 1995, the Company's Board of Directors
authorized, and in 1996, the Company's shareholders approved, a reserve of
250,000 shares of the Company's common stock for issuance to Non-Employee
Directors of the Company, pursuant to the 1995 Non-Employee Director Plan (the
"1995 Director Plan"). Options granted under the 1995 Director Plan are
exercisable on a cumulative basis, with one third exercisable as of the date of
grant and the remainder becoming exercisable in equal installments on each of
the first and second anniversaries of the date of grant. Each option expires and
is no longer exercisable on the date ten years from its date of grant. Options
to purchase 42,000 shares at $13.38 and 10,500 shares at $12.25 per share were
granted during 1995 and 1996, respectively.

     ACCOUNTING FOR STOCK-BASED COMPENSATION: In October 1995, the Financial
Accounting Standards Board Issued Statement No. 123, "Accounting for Stock-Based
Compensation (SFAS 123)", a new standard of accounting and reporting for stock-
based compensation plans. The Company has adopted this new standard in 1996. The
Company has continued to measure compensation cost for its stock-based
compensation plans using the intrinsic value-based method of accounting its has
historically used and, therefore, the new standard has no effect on the
Company's operating results.

     Had the Company used the fair value-based method of accounting for its 1991
Stock Incentive Plan and 1995 Non-Employee Director Plan beginning in 1995 and
charged this compensation cost along with the value of the shares granted
through the Employee Stock Purchase Plan against income, over the plans' vesting
periods, based on the fair value of options at the date of grant, net income and
net income per share for 1996 and 1995 would have been as follows:

                                                         1996        1995

     The pro forma information above includes stock options granted, as well as
purchases under the Employee Stock Purchase Plan, in 1995 and 1996.

     The fair value of each option grant was estimated on the date of grant
using the Black-Scholes option-pricing model for the 1991 Stock Incentive Plan
and the 1995 Non-Employee Director Plan. The assumptions for 1996 and 1995 were
as follows:
                                      1996                    1995

     WARRANTS: In connection with the completion of its initial public offering
of common shares in 1992, the Company granted to the representatives of the
underwriters warrants for 90,000 shares of common stock at an exercise price of
$6.60 per share. During 1996 the Company issued 85,000 shares of common stock
pursuant to the exercise of the warrants. At December 31, 1996 there are 5,000
shares of common stock to be issued upon the exercise of the remaining warrants.

     EMPLOYEE STOCK PURCHASE PLAN: The AVECOR Cardiovascular Inc. Employee Stock
Purchase Plan ("Stock Purchase Plan"), which is available to substantially all
employees, enables eligible employees to contribute up to 10% of their wages
toward quarterly purchases of the


                                       16
<PAGE>


Company's common stock at 85% of market value on the first or last day of each
calendar quarter, whichever had the lower stock price. Employees purchased
23,000 shares at an average price of $11.00 per share in 1996, 18,000 shares at
an average price of $10.17 per share in 1995, and 23,000 shares at an average
price of $6.18 per share in 1994. At December 31, 1996, 16,000 additional shares
were reserved for future employee purchases of stock under this plan.

     SHAREHOLDER RIGHTS PLAN: In June 1996 the Company adopted a shareholder
rights plan, pursuant to which the Company declared a dividend distribution of
one Preferred Share Purchase Right on each share of the Company's Common Stock
outstanding on August 2, 1996. Each Right will entitle the holder to buy one-
thousandth of a share of the Company's Series A Junior Preferred Stock, or a
combination of securities and assets of equivalent value, at an exercise price
of $80.00, subject to adjustment. The description and terms of the Rights are
set forth in a Rights Agreement dated June 26, 1996, between the Company and
Norwest Bank Minnesota, N.A., as Rights Agent.

6. COMMITMENTS AND CONTINGENCIES:

LEASES: In 1996 and years prior, the Company leased all of its facilities and
certain equipment pursuant to operating leases. The leases for the Company's
United States operating facilities expired in December 1996. The Company's
facility near Glasgow, Scotland is leased for a period of ten years ending in
October 2003. This lease agreement provides for adjustment of minimum rentals
based upon market rates in 1998 and requires minimum monthly rental payments
plus real estate taxes and applicable common facility operating expenses.

     Rent expense, including allocated real estate taxes and operating expenses,
under all rental agreements was $725,000, $596,000 and $587,000 for the years
ended December 31, 1996, 1995 and 1994, respectively. The following is a
schedule of future minimum lease payments pursuant to the terms of the 
non-cancellable leases for the Glasgow, Scotland facility described above:

     PURCHASE OF FACILITY: In January 1997, the Company purchased a new
corporate headquarters and manufacturing facility for $9,650,000 and
consolidated its former four separate U.S. facilities. In connection with this
purchase, the Company entered into a $5,167,000 bank note payable agreement in
January 1997 and, in addition, utilizing restricted cash and investments (see
Note 1), funded $4,483,000 of the remaining cost of construction of the new
building.

     The bank note payable agreement bears interest at 8.11% and requires
monthly principal payments of $21,531, plus interest, through January 2002 with
the remaining principal and interest due February 2002. The bank note payable is
collateralized by the new corporate headquarters and manufacturing facility and,
among other things, requires the Company to meet certain ratios related to
leverage, debt service and cash flow. Additionally, the bank note payable
agreement prohibits the Company from distributing dividends to its shareholders.
     Principal payments on the bank note payable are
as follows:

     ROYALTY AGREEMENT: In connection with the Company's June 1991 acquisition
of the Surgical Division of SCIMED Life Systems, Inc. (the Predecessor
Business), the Company entered into a royalty agreement with SCIMED. The
agreement required the Company to make payments to SCIMED primarily based on net
sales (as defined), through June 1996, of products previously manufactured by
the Predecessor Business as of the acquisition date. The Company has incurred
royalties of $95,000, $178,000, and $213,000 for the years ended December 31,
1996, 1995 and 1994, respectively, under this agreement.

     The agreement also provides for royalty payments should the Company develop
and sell new products (new generation products) using certain technology
embodied in product models developed by the Predecessor Business. This element
of the agreement expires in June 2001. The Company has not paid or incurred any
such royalties through December 31, 1996.

     PRODUCT LIABILITY: The Company is self-insured on product liability claims
below a certain dollar limitation and maintains product liability insurance
above this limitation per claim and in the aggregate.

     CONFIDENTIALITY AND NON-COMPETE AGREEMENTS: The Company has entered into
confidentiality and non-compete agreements with certain employees. If any of
these employees are terminated, the Company is conditionally required to pay the
employee 75% of his or her base salary, as defined, during the non-compete
period (one to two years) if the employee remains unemployed during
this period.

7. INDUSTRY SEGMENT INFORMATION:

The Company distributes its products through its direct sales force and
independent sales representatives. Additionally, the Company distributes its
products through domestic and foreign independent distributors who then market
the products directly to medical institutions. While sales to certain of the
Company's independent distributors exceed 10% of the Company's 1995 and 1994 net
sales, management does not believe the Company is primarily dependent upon any
one distributor for the ultimate sale of products to medical institutions. Sales
to distributors accounting for 10% or more of the Company's net sales were as
follows:

                             1996      1995           1994

Distributor #2 . .           (1)    $3,503,000        (1)

(1) Accounted for less than 10% of the Company's net sales.

     Total export sales from the U.S. to unaffiliated entities (primarily to
Europe and payable in U.S. dollars) were $4,912,000, $3,480,000 and $3,365,000,
respectively, for the years ended December 31, 1996, 1995 and 1994.

     At December 31, 1996 and 1995, consolidated accounts receivable include
$3,738,000 and $3,093,000, respectively, due from customers located outside of
the U.S.

     During the years ended December 31, 1996, 1995, and 1994, AVECOR
Cardiovascular Ltd. made capital expenditures of approximately $146,000, $57,000
and $320,000, respectively.

8. RETIREMENT SAVINGS PLAN:

The AVECOR Cardiovascular Inc. Retirement Savings Plan (the "Savings Plan") is a
profit sharing plan which provides for voluntary pre-tax employee contributions
and discretionary employer matching and profit sharing contributions and is
intended to satisfy the requirements of Section 401(k) of the Internal Revenue
Code. Generally, all employees of the Company who are over 21 years of age and
who have completed one year of service with the Company are eligible to
participate in the Savings Plan. The Company approved contributions of $23,000
and $10,000 to the Savings Plan in 1996 and 1995, respectively. The Company did
not make any contributions to the Savings Plan in 1994.

9. INCOME TAXES:

The components of the Company's income tax provision (benefit) are as follows:

     The variance of the 1996 effective tax rate from the statutory tax rate was
primarily due to losses incurred by the Company's French subsidiary for which no
tax benefit has been recorded because of the uncertainty of their realization.
The variance of the 1995 effective tax rate from the statutory tax rate was
primarily due to utilization of $1,730,000 of net operating loss carryforwards
("NOLs") and $26,000 of state research and experimentation credits.

     Components of the Company's deferred tax assets and liabilities are as
follows:

     The company has established a valuation allowance to offset its deferred
tax asset related to its French subsidiary's NOL carryforwards due to the
uncertainty of their realization. The nol carryforwards expire from 2000 to
2001. The Company expects its future taxable income will be sufficient to
realize its other deferred tax assets, therefore there is no valuation allowance
offsetting them.

     Available research and experimentation credits at December 31, 1996,
represent federal and state amounts of approximately $370,000 and $190,000,
respectively, with expiration dates ranging from 2007 to 2011.

     Undistributed earnings of the Company's foreign subsidiary are indefinitely
reinvested in foreign operations. Accordingly, no provision has been made for
income taxes that might be payable upon remittance.

10. PATENT MATTERS:

In 1996, the Company reached an agreement with COBE Laboratories Inc. (COBE) to
settle COBE's patent suit against the Company.

     The terms of the settlement with COBE provide for the Company to make net
payments totaling $2,200,000, of which a net $1,100,000 was paid in August 1996
for settlement of the suit as well as certain license rights. The net settlement
costs of $2,200,000 and the associated legal costs were recognized as a charge
to operations in 1996. The remaining amount is payable on or about August 6,
1997, subject to COBE's active enforcement of its claimed patent rights with
respect to other manufacturers.

     In March 1997, the Company filed suit in U.S. District Court for the
District of Minnesota, seeking to invalidate a newly issued U.S. patent held by
a competing manufacturer of blood oxygenators and other medical devices, and
requesting a determination that the Company's Affinity oxygenator does not
infringe the competitor's patent. The Company filed suit in response to a
December 1996 letter from the competitor, alleging that the Affinity oxygenator
infringes certain claims under the competitor's patent, and requesting
discussion regarding a possible license agreement. The Company reviewed the
subject patent and concluded, based on an opinion from its patent counsel, that
none of the claims in the patent are infringed by the Affinity oxygenator, and
that the patent is, in any event, invalid. However, the expense and effort
potentially required to bring this action, as well as the outcome of any
counterclaim successfully brought against the Company by the competitor, could
have a material adverse effect on the Company's business, financial condition
and results of operations.

11. QUARTERLY DATA (UNAUDITED):

Quarterly net sales, gross profit, net income (loss) and net income (loss) per
share data are presented on page 20.

12. RECLASSIFICATIONS:

Certain reclassifications were made to the 1995 and 1994 financial statements to
conform to the 1996 presentation. These reclassifications had no effect on
previously reported total assets, total liabilities, shareholders' equity or net
income (loss).

REPORT OF INDEPENDENT ACCOUNTANTS
To the Shareholders and Board of Directors of
AVECOR Cardiovascular Inc.:

We have audited the accompanying consolidated balance sheets of AVECOR
Cardiovascular Inc. as of December 31, 1996 and 1995, and the related
consolidated statements of operations, changes in shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of AVECOR
Cardiovascular Inc. as of December 31, 1996 and 1995, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1996, in conformity with generally accepted accounting
principles.
