PART I

ITEM 1 - BUSINESS

    (a) GENERAL DEVELOPMENT OF BUSINESS

Bio-Vascular, Inc. develops, manufactures and markets proprietary specialty
medical products for use in thoracic, cardiac, neuro and vascular surgery
(the "Surgical Business").  The Company's products include the Tissue-Guard
product line and the BIOGRAFT peripheral vascular graft.  The Tissue-Guard
product line includes various configurations of bovine pericardium (the thin
membrane surrounding the heart of cattle) processed using the Company's
proprietary tissue-fixation technologies.  The Tissue-Guard products are used
in a wide variety of surgical procedures and are designed to reinforce,
reconstruct and repair tissue and prevent leaks of air, blood and other body
fluids.  BIOGRAFT is used to bypass blocked blood vessels and is produced
from modified human umbilical veins.  The Surgical Business also markets and
sells two surgical tools used in cardiac and vascular surgery.  In addition,
the Company has an early stage medical imaging software business which
develops, markets and supports certain software products for interactive
visualization and analysis of three dimensional ("3-D") image data (the
"Medical Imaging Software Business").

The Company's PERI-STRIPS surgical staple line reinforcement product was
added to the Tissue-Guard product line in 1994 and has been primarily
responsible for the Company's revenue growth in fiscal 1994 and fiscal 1995.
PERI-STRIPS are special configurations of tissue produced from bovine
pericardium using proprietary tissue preservation, sterilization and other
tissue-fixation techniques developed by the Company.   PERI-STRIPS are used
primarily in lung volume reduction ("LVR") surgery and other surgical
procedures on the lung.  LVR surgery is performed principally on patients
with late-stage emphysema who have significantly reduced respiratory
function.  During the procedure, a portion of each diseased lung is removed
from the patient to provide relief from the symptoms of emphysema.
PERI-STRIPS are designed to prevent air leakage at the surgical staple line
which is essential to successful LVR surgery.  Early data available to the
Company suggests that after undergoing the procedure, patients have improved
breathing capacity, improved exercise tolerance and improved quality of life.
 However, there presently does not exist a statistically significant body of
clinical data from which to draw conclusions concerning the efficacy and
long-term outcomes associated with the LVR procedure.  The American Lung
Association estimates that in 1992 there were approximately 1.9 million
Americans suffering from emphysema.  However, only a small portion of those
suffering from emphysema have late-stage emphysema and meet certain surgical
criteria and are therefore considered candidates for the LVR procedure.

The Company also manufactures and markets a number of other products in its
Tissue-Guard product line.  DURA-GUARD, a dural patch used in cranial
surgery, is designed to reduce post-surgical adhesions and fluid leakage.
VASCU-GUARD, a vascular patch used primarily in carotid endarterectomy
procedures, is designed to improve tissue integration and reduce suture line
bleeding.  In addition, the Company markets SUPPLE PERI-GUARD and PERI-GUARD
as a general soft-tissue patching material for use in specialty surgical
procedures.

In May 1994, the Company acquired Vital Images, a company involved in the
development, marketing and support of certain software products for
three-dimensional ("3-D") visualization and analysis of image data. In
August 1995 the Company  granted an exclusive, perpetual, world-wide source
code license for its GeoScience imaging technology to a third party and is
now focused solely on medical applications of its imaging technology.  See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition - Overview" on page 28 of this Annual Report on Form 10-K. The
Company  initially developed its VOXELVIEW high- speed, volume imaging
software as a research tool.  The Medical Imaging Software Business has
further developed VOXELVIEW to provide complete and accurate 3-D rendering of
data collected by advanced scanning devices such as spiral computed
tomography ("CT") scanners, magnetic resonance imaging devices ("MRI"),
positron emission tomography scanning devices ("PET") and ultrasound
sonagraphic devices ("Ultrasound"). This product has been licensed to
approximately 80 medical and research institutions as a research tool.  In
December 1995, the Company


                                     2

<PAGE>

received notice of clearance from the U.S. Food and Drug Administration ("FDA")
to market VOXELVIEW as a clinical diagnostic and surgical planning device
when used in conjunction with CT and MRI image data.  The Medical Imaging
Software Business is continuing development and commercialization of an
improved version of VOXELVIEW, which is intended to assist physicians in
clinical diagnosis, surgical planning and patient screening.

The Company was incorporated in Minnesota in July 1985. As used herein, the
term "Company" refers to Bio-Vascular, Inc. and its wholly-owned subsidiary
Vital Images, Incorporated, an Iowa corporation. The Company's principal
executive offices are located at 2575 University Avenue, St. Paul, Minnesota
55114-1024, and its telephone number is (612) 603-3700.  Vital Images'
offices are located at 505 North Fourth Street, Fairfield, Iowa 52556, and
its telephone number is (515) 472-7726.

    (b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The Company's  operations are divided into two business segments: the
Surgical Business and the Medical Imaging Software Business.  Financial
information about these segments is contained on page 51 of this Annual Report
on Form 10-K.

    (c) NARRATIVE DESCRIPTION OF BUSINESS

SURGICAL BUSINESS

    MARKETS AND MEDICAL NEED

While the trend in medicine is toward less invasive surgical procedures,
substantially all surgical procedures, whether invasive or not, involve the
cutting of tissue to access, repair or remove tissue at or from the surgical
site.  Tissue which has been cut must either be repaired or replaced so that
it can heal properly.  Proper repair of incised tissue is dependent upon a
number of variables, including whether (i) the repair must be leakproof,
either for air, blood or other body fluids, (ii) the incised tissue is under
tension or subject to shrinkage such that additional tissue is needed to
bridge the two tissue surfaces to be repaired, and (iii) the tissue subject
to the repair must be strengthened to accommodate the natural stresses of the
human body.  In certain instances, suturing of two tissue surfaces will be
effective.  In other instances, however, a patching material, whether
autologous (from the body of the patient), synthetic (from man-made
materials) or tissue-based (from processed tissue), may be needed.  The
Company's tissue-based products are designed to fulfill the medical need for
repairing human tissue and preventing leaks at the surgical site in certain
existing surgical procedures, as well as offering a potential medium for
techniques and procedures currently being developed.

The Company's core competency is the development and manufacture of
tissue-based implantable medical products for use by surgeons in various
surgical procedures where reinforcing, reconstructing and repairing tissue
and preventing leaks of air, blood or other body fluids is necessary for the
achievement of a favorable outcome.  Historically, surgeons primarily used
autologous tissue in situations where tissue repair was necessary.
Harvesting the autologous material, which is still performed in many
circumstances, necessarily requires that the surgeon cut into another part of
the patient's body.  The second surgical site increases the cost of the
procedure and lengthens the time the patient is under anesthesia, thereby
increasing the risk of complication and resulting in additional pain and
recovery time for the patient. To the extent a surgeon is confident that the
performance of a readily available medical product, whether tissue-based or
synthetic, is equal to or is better than the patient's own tissue, the
Company believes the surgeon will choose the tissue-based or synthetic
product to avoid a second surgical site as a means of reducing costs and
improving outcomes.

Surgical procedures that are enabled or enhanced by the Company's
tissue-based products include lung volume reduction, craniotomy, carotid
endarterectomy and lower limb vascular reconstruction.  Sales of the
Company's products used in these procedures accounted for 50% of the
Company's net revenue in fiscal 1994 and 54% of the Company's net revenue in
fiscal 1995.

LUNG VOLUME REDUCTION (LVR) SURGERY.  Emphysema, most often caused by
cigarette smoking, is a progressive disease of the lungs characterized by
air-filled expansions or pocket-like blisters in the tissue of the lungs.
Because the air in the lungs

                                      3

<PAGE>

cannot be fully expelled, the effort to inhale fresh air becomes increasingly
difficult, pushing the lung walls farther out and causing the lungs to expand
and lose their elasticity.  The diaphragm, the major muscle used for
breathing, becomes flattened and loses its ability to function.  As the
disease advances and patient health is progressively compromised, breathing
becomes more difficult.  Persons with late-stage emphysema eventually become
incapable of even minor physical activity and often become dependent upon
continuous supplemental oxygen even when at rest. As a result, late-stage
emphysema can significantly reduce mobility, leaving individuals with
late-stage emphysema unable to care for themselves or engage in normal daily
activities.  Because of the weakened respiratory condition of these patients,
common illnesses involving pulmonary functions can result in emergency room
visits and hospitalization.

Non-surgical therapies for patients suffering from emphysema include (i)
bronchodilators (pills and inhalers), to open up airways to temporarily
relieve wheezing or shortness of breath, (ii) steroids, to reduce
inflammation in the airways, (iii) pulmonary rehabilitation to increase
endurance, and (iv) oxygen supplements to help decrease the feeling of
shortness of breath. Each of these non-surgical therapies, however, offers
only temporary relief and each becomes less effective as the disease
progresses.  Data gathered by the Company indicates that the cost of
medication and oxygen supplements for late-stage emphysema patients can range
from $5,000 to $8,000 annually.  In addition, for persons suffering the
effects of late-stage emphysema, the need for periodic emergency room care
can increase costs substantially.

Lung transplantation is the only known cure for emphysema.  A lung transplant
surgical procedure, however, costs up to $250,000 and is typically used only
as a last resort because of the high degree of risk associated with the
procedure, an inadequate supply of donor lungs, and the requirement that the
patient receive anti-rejection drugs for the remainder of his or her
lifetime. Only 688 lung transplants were performed in the United States in
1994.

In the 1950's, a surgical procedure was developed to treat the symptoms of
late-stage emphysema by removing damaged lung tissue.  Due to air leaks
around the suture lines, these experimental LVR procedures resulted in a high
mortality rate and long, painful post-surgical recovery periods.  As a
result, the LVR procedure was abandoned.  In the late 1980's, various
surgeons began to develop specialized techniques for accessing and resecting
the lung.  The use of surgical staples was introduced to perform the LVR
procedure more quickly, a particularly important consideration in light of
the debilitated condition of the patients requiring the surgery. Despite many
advances in the LVR procedure, multiple small air leaks caused by the staples
in the lung continued to limit the effectiveness of the procedure.  In 1994,
Dr. Joel Cooper, a pioneer in lung transplant surgery, modified the LVR
procedure using strips of SUPPLE PERI-GUARD to reinforce the staple line to
prevent air leakage around the staples.

During LVR surgery, the surgeon collapses one lung, while allowing the
patient to continue breathing with the other lung with supplemental oxygen.
Using a stapling device, the surgeon removes sections of damaged tissue,
typically 20% to 30% of each lung.  The Company's PERI-STRIPS, manufactured
from processed bovine pericardium, are used to strengthen these staple lines
and prevent air leakage.  By removing the most diseased tissue, the remaining
lung tissue has room to expand, improving breathing capacity by, among other
things, enabling the muscles used in breathing to regain their function and
allowing the rib cage and diaphragm to return to their normal size.  The
Company estimates that the current cost of an LVR surgical procedure ranges
from $30,000 to $45,000 per procedure.

The American Lung Association estimates that in 1992 there were approximately
1.9 million Americans suffering from emphysema.  The LVR procedure, however,
is currently only being performed on a small portion of these patients who
have late-stage emphysema and who meet certain criteria established by the
attending surgeons.  Currently, most surgeons require that an LVR candidate
be less than 75 years old, quit smoking at least six months prior to LVR
surgery, have no documented history of heart disease or previous lung surgery
and have no other major diseases.  In addition, most surgeons performing the
LVR procedure require that candidates have documented lung function testing
and chest x-rays detailing the severity of the condition.  The Company
believes that the patient selection criteria will continue to be refined as
surgeons become more familiar with the LVR procedure and as long-term
clinical results become available.

While LVR surgery is not a cure for emphysema, the results from the procedure
to date are encouraging based on information available to the Company.
Generally, this information suggests that patients undergoing the procedure
have reduced


                                       4

<PAGE>

shortness of breath, improved exercise tolerance and improved quality of
life. However, LVR surgery was only re-introduced into the United States in
late calendar 1993.  As a result, the number of patients who have undergone
the procedure and for whom a clinically acceptable post-operative period of
evaluation has elapsed, while growing, is still relatively small. Similarly,
the number of physicians performing the procedure and from whom data and
reporting is available is small.  Accordingly, there presently does not exist
a statistically significant body of clinical data from which to draw
conclusions concerning the efficacy and long-term outcomes associated with
the LVR procedure.  The Company believes that patients who have received the
LVR procedure may require an additional year or more of follow-up examination
before the procedure can be properly evaluated by the medical community.

CRANIOTOMY.  Craniotomies (surgical operations involving the brain and skull)
are typically performed to treat various brain conditions, such as tumors,
aneurysms, blood clots, head injuries and abscesses.  To access the brain,
the surgeon is required to cut through several of the protective layers
surrounding the brain.  The dura, the fibrous protective layer below the
skull, protects the brain and spinal cord from bacterial infection and trauma
and provides a fluid tight seal.  Once the surgeon has cut through the scalp
and the skull, the dura must be cut with a scalpel or scissors and resected
to expose the brain.

After the specific brain condition has been treated by the surgeon, the dura
often must be closed to prevent cerebral spinal fluid leakage.  While the
dura is often closed with direct suture, surgeons who consider the prevention
of fluid leakage to be critical to the success of the operation will use a
dural patch.  Dural patches currently available are either autologous or are
produced form the processed cadaver tissue or bovine pericardium.  The
Company's DURA-GUARD Dural Repair Patch is designed to be sewn to the dura to
close the incision by fusing to the native dura with little or no adhesion
(an abnormal union between two tissue surfaces not intended to be joined) to
the underlying brain cortex.

The Company estimates that in the United States approximately 100,000 cranial
operations were performed in 1994.  Whether a dural patch is used in such
operations is subject to surgical conditions and surgeon discretion.  Dural
patching is most often used when the dura shrinks after incision such that
sutures alone may not provide adequate closure.

CAROTID ENDARTERECTOMY.  Stroke is the third leading cause of death in the
United States with an estimated 500,000 new cases per year.  The build-up of
atherosclerotic plaque (fat deposits with a proliferation of fibrous
connective cells along the artery walls) in the carotid arteries (the
principal arteries located in the neck that supply blood to the brain)
increases the risk of stroke.  A substantial portion of strokes is caused by
a fragment of atherosclerotic plaque breaking away from the inner wall of the
carotid artery and becoming lodged in an artery in the brain.

Drug therapy is often prescribed to treat the early indications of
atherosclerotic plaque build-up.  If the condition progresses to a point
where drug therapy is not effective, surgical intervention may be required.
Carotid endarterectomy is a surgical procedure used to remove atherosclerotic
plaque build-up in the carotid artery.  The endarterectomy procedure begins
with an incision in the internal carotid artery.  A temporary shunt may be
inserted to maintain blood flow to the brain during the surgery.  Once the
artery is opened, the plaque and inner layer of the artery are carefully
removed, and the incised artery must be repaired.  Although the artery often
can be closed without a patch, use of an autologous or prosthetic patch is
often suggested to expand the artery, encouraging greater blood flow.  In
addition, certain patients require patching due to the small size of their
carotid arteries, or in some patients with a normal carotid artery diameter,
a patch is used to decrease the incidence of post-operative stenosis or
occlusion.

While the Company estimates that in the United States approximately 100,000
carotid endarterectomy procedures were performed in 1994, the use of a
patching material in such procedures is subject to surgeon discretion.  Once
a surgeon determines a vascular patch is necessary or desirable, the surgeon
has additional discretion in determining the type of patching material to
use. Characteristics of an effective vascular patch include the ability to
imitate human tissue, to exhibit good blood flow characteristics and to
reapproximate around sutures to prevent blood leaks.  The primary patching
materials include autologous tissue, synthetic patches made out of
polytetraflurothylene ("PTFE"), silicone fabric or tissue-based patches
made out of bovine pericardium, such as VASCU-GUARD.

LOWER LIMB VASCULAR RECONSTRUCTION.  Certain diseases, such as diabetes, can
cause a restriction or occlusion in the arteries which provide blood to the
legs.  If left untreated, insufficient blood flow can ultimately result in the
need for amputation.  If drug therapy is not deemed an effective treatment based
upon the severity of the restriction or blockage, the use of a graft in
peripheral vascular reconstructive surgery may be needed.  In this type of
surgical procedure, the surgeon can bypass the blocked artery to regain blood
circulation, thereby saving the affected limb.  Diabetics, in particular, are
often at risk for amputation of a lower limb due to insufficient blood flow in
the femoral artery in the thigh.  By implanting a graft from the upper portion
of the femoral artery to either the lower femoral artery or to the popliteal
artery blow the knee, the surgeon is able to increase blood flow below the site
of the restriction or blockage.  Long-term patency (openness), and a thrombo-
resistant surface that provides smooth blood flow are essential qualities of an
effective graft.

Saphenous veins (autologous veins from the leg) typically provide the most
effective grafting material.  In many instances, however, a suitable saphenous
vein may be unavailable in sufficient quantity or quality, and a substitute
graft must be used.  The primary alternative substitute grafts involve synthetic
grafts made from PTFE or bio-synthetic materials or tissue-based grafts, such as
BIOGRAFT.  The Company estimates that in the United States approximately 55,000
lower limb vascular reconstructions were performed in 1994.

TISSUE-GUARD PRODUCT LINE. The Company's Tissue-Guard products are all produced
from bovine pericardium. Many of the product characteristics and competitive
advantages of this product line are derived from the collagen configuration of
the bovine pericardium. Collagen, which is a fibrous protein found in all multi-
cellular animals, makes the pericardium durable and provides superior fluid
interface properties, similar to autologous  tissue. These characteristics allow
for effective host tissue incorporation. Host cells deposit a collagen matrix on
the surface of the pericardial product, which helps the Tissue-Guard product
integrate into the host tissue and which the Company believes enhances the long-
term tensile strength (the maximum stress a material subjected to a stretching
load can withstand without tearing) of all the products in the Tissue-Guard
product line.

The Company processes the bovine pericardium using proprietary tissue-fixation
technologies. The tissue is treated with glutaraldehyde and other proprietary
chemical treatments to prevent degradation of the tissue and to render it
biologically compatible with the host tissue. As a result of the Company's
proprietary tissue-fixation technologies, the Tissue-Guard products have a shelf
life of three years and resist infection, which potentially reduces hospital
recovery time and the need for drugs and future surgical intervention. In
addition, according to studies commissioned by the Company, the tissue-fixation
technologies used by the Company reduce the level of residual glutaraldehyde
remaining in the processed tissue to less than six parts per million, resulting
in a lower incidence of host tissue inflammatory response and promoting host
tissue incorporation similar to the body's natural healing process.

Surgeons have indicated that different pericardial patch characteristics are
useful in different surgical procedures. Accordingly, depending on the
particular tissue-fixation technology used by the Company, the bovine
pericardium is processed into either SUPPLE PERI-GUARD or PERI-GUARD. While the
raw material used is the same, SUPPLE PERI-GUARD has greater elasticity and
flexibility than PERI-GUARD, which allows for greater conformity to the surgical
site. The Company's PERI-GUARD and SUPPLE PERI-GUARD products are produced in
square or rectangular sheets of different sizes, ranging from 4 cm x 4 cm to
12 cm x 25 cm.  SUPPLE PERI-GUARD is produced for use as a multi-purpose
material designed for reinforcing, reconstructing and repairing tissue and
preventing leaks of air, blood and other body fluids. Each of such products
has received 510(k) clearance from the FDA as a general soft-tissue patch.

The products in the Tissue-Guard product line described below are special
configurations of SUPPLE PERI-GUARD designed to enable specific surgical
procedures.

PERI-STRIPS. PERI-STRIPS, staple line reinforcements, are currently used
primarily in LVR surgery but are also used for lobectomy (removal of a lobe),
excision/destruction of a lesion and segmental resection of the lung. The key
competitive features of PERI-STRIPS include the following:


                                      7


<PAGE>



- -  REAPPROXIMATION. Due to the elastic-like nature of the collagen fibers in
   the tissue, PERI-STRIPS reapproximate (close around) surgical staples to
   prevent pulmonary air leaks at the staple site.

- -  PREVENTS ENLARGEMENT. The elasticity of PERI-STRIPS prevents staple holes
   from enlarging, which could lead to additional air leaks and require
   additional surgery.

- -  REINFORCEMENT. The use of PERI-STRIPS strengthens the entire staple line,
   which makes it more durable and less likely to tear. Also, PERI-STRIPS are
   thin enough to allow for staple lines to be overlapped, which is often
   required during the LVR procedure.

- -  SLEEVE CONFIGURATION. The sleeve configuration of PERI-STRIPS is customized
   to fit disposable, reusable and endoscopic staplers of varying sizes and
   produced by different manufacturers. The sleeve configuration allows for
   greater ease of use and reduced surgical time resulting in lower costs.

The Company estimates its net revenue per LVR procedure to be approximately
$1,500.

DURA-GUARD. DURA-GUARD, a dural repair patch, is primarily used in craniotomy
procedures when the dura must be repaired and suturing without a patch is not
deemed sufficient. DURA-GUARD offers advantages over competitive dural patches
produced from autologous or cadaver tissue. Harvesting autologous tissue
necessarily involves a second surgical site, thereby increasing costs and
recovery time. Cadaver tissue is subject to rigorous tissue bank regulations,
which could impact upon the availability of such tissue, and is considered by
some to present a greater risk of disease transmission than bovine pericardium.
Certain other competitive advantages of DURA-GUARD relate to the specific
benefits produced by the physical properties of DURA-GUARD in connection with
the craniotomy procedure. Observations in the course of subsequent surgical
procedures on patients receiving DURA-GUARD patches have shown that there is
little or no adhesion formation on the DURA-GUARD surface that faces the
cerebral cortex, a complicating factor following any cranial surgery. In
addition, Company commissioned studies have shown that fibrous bone cells invade
the DURA-GUARD surface facing the cranium, as they do the human dura, inviting
good host tissue incorporation. The collagen configuration of the processed
bovine pericardium in DURA-GUARD reapproximates around the sutures used to affix
the patch, thereby providing a barrier between the skull and the tissue layers
underlying the dura and preventing the leakage of cerebrospinal fluid. To date,
synthetic materials have been unable to perform as effective dura substitutes
and have been associated with late subdural hematoma formation (bleeding between
the dura and the brain).

VASCU-GUARD. VASCU-GUARD, a vascular repair patch, is primarily used in carotid
endarterectomy procedures when the carotid artery must be repaired and closing
the vessel without a patch is not deemed sufficient. VASCU-GUARD offers
advantages over competitive carotid artery repair patches produced from
autologous tissue or synthetics. The use of autologous tissue necessarily
involves a second surgical site and results in increased costs and additional
recovery time. Synthetic patches, which lack the collagen configuration of
tissue, do not reapproximate around sutures as does the VASCU-GUARD product,
thereby increasing the risk of suture line bleeding and resulting in longer
operating times. In addition, unlike synthetic patches, the physical attributes
of VASCU-GUARD imitate human tissue and certain characteristics associated with
human tissue. Specifically, Company commissioned studies have shown that, once
healed, VASCU-GUARD supports endothelialization (growth of a cell layer normally
lining the interior of blood vessels) and its non-thrombogenic blood flow
surface imitates the blood flow characteristics of autologous vessels. In
addition, its pulsatility (ability to reflect movement signifying the rhythmic
pumping of the heart) allows the surgeon to readily verify normal blood flow
after implantation.

BIOGRAFT . BIOGRAFT, a peripheral vascular graft manufactured from human
umbilical veins, is indicated for use in lower limb vascular reconstructions
when a saphenous vein is not available. BIOGRAFT offers advantages over
competitive vein grafts produced from synthetics, like PTFE, due to its thrombo-
resistant surface which provides smooth blood flow and minimizes turbulence and
risk of occlusion. Other competitive advantages of BIOGRAFT include its long-
term patency and its similarity to an autologous blood vessel, minimizing
intimal hyperplasia (a build up of cells on the interior of the blood vessel
which results in restricted blood flow). In addition, a knitted and supportive
Dacron mesh is placed around the graft, which allows


                                      8

<PAGE>



for easier handling and promotes tissue integration for strength and stability.

SURGICAL PRODUCTIVITY TOOLS.  FLO-RESTER AND BIO-VASCULAR PROBE.  The Company's
FLO-RESTER products are vessel occluders manufactured from medical grade
silicone. The FLO-RESTER products are designed to interrupt blood flow in
arteries and to stent them (hold them open) during surgery, thereby facilitating
the suturing together of vessels. These products are primarily used during
coronary artery bypass graft surgeries in which blood is routed past the heart
through a heart-lung bypass machine in order to keep the heart free of blood
during surgery. During such procedures, incidental blood flow obstructs the
surgeon's view of the operative site and interferes with precise suturing. FLO-
RESTER consists of a flexible shaft with small bulbs at each end that are
inserted into the blood vessel at the point where the artery bypass is sutured
to the artery to stop the blood flow. Competitive procedures involve external
occlusion through the use of clamps, snares or tapes. The BIO-VASCULAR PROBE is
a flexible shaft with varying sizes of bulbous tips on either end. Surgeons use
the BIO-VASCULAR PROBE to locate occlusions or blockages in arteries and to
ascertain the blood flow characteristics of arteries. The BIO-VASCULAR PROBE is
inserted and fed into an artery. When the tip of the probe meets resistance, the
surgeon is able to identify the exact location of the occlusion. The BIO-
VASCULAR PROBE is then extracted and a bypass is completed below the occlusion.
In addition, the Probe can be used to atraumatically lift the edge of the
incision to assist the surgeon in accurately placing sutures, which can improve
the functioning of bypass grafts.

  RESEARCH AND DEVELOPMENT

The Company generally allocates its research and development resources among
three broad functions in its Surgical Business: supporting current products
through training of Company personnel and writing and publishing research papers
on existing products; developing product line extensions by improving current
products or developing new applications for current products; and developing new
products for surgical uses that utilize the Company's proprietary technologies
and core competencies in tissue processing and bio-materials.

As an integral part of both its research and development and sales and marketing
strategies, the Company strives to involve its surgeon-customers to a large
extent in its product development activities. The Company consults with selected
surgeons frequently as to market needs and assessments of products under
development. The Company believes that this practice allows it to receive
surgeon assessments of products in development at an early stage.

The Company's Surgical Business research and development staff currently
consists of three scientists and two technicians. The Surgical Business also
expands its research and development activities through the use of external
consultants and research staff and facilities at research centers and hospitals
on an as-needed basis.  The Company spent approximately $643,000, $414,000 and
$240,000 on research and development for the Surgical Business in fiscal 1995,
1994 and 1993, respectively.  For information about Company-wide research and
development expenses, see the Consolidated Financial Statements on page 39 of
this Report.

  MARKETING

The sales and marketing strategy of the Surgical Business includes developing
and maintaining a close working relationship with the hospitals and surgeons
which purchase and use the Company's products in order to assess and satisfy
their needs. The Company's current primary marketing focus is assisting in the
education of surgeons in the use of PERI-STRIPS in LVR surgery through
sponsorship of workshops and training programs. These workshops and training
sessions are being conducted in the United States, Canada and certain European
and Far Eastern countries. The Company estimates that approximately 500 surgeons
have been trained in LVR surgery as of the end of fiscal 1995. The Company also
sponsors surgeon workshops and training programs in the use of BIOGRAFT.

The Company's sales and marketing strategy is also designed to ensure that the
Company has an innovative "first in the mind of the customer" focus that
results in timely and effective marketing programs and new product
introductions. These programs include surgical trade shows, support of the
presentation of clinical data and new product information by key physicians,
limited direct-mail campaigns and the development of strategic physician
alliances and utilization of the


                                      9

<PAGE>


Company's scientific advisory boards. The Company believes these efforts to
be cost effective in producing awareness of, and loyalty to, the Company's
products.

The Company's Surgical Business products are sold to hospitals and surgeons
worldwide. For the fiscal years ended October 31, 1995, 1994 and 1993,
approximately 17%, 30% and 33% of the Company's Surgical Business net revenue,
respectively, were to international markets. The decrease in the percent of
Surgical Business net revenue attributed to international markets during fiscal
1995 was primarily due to increases of sales of PERI-STRIPS in the United
States. The majority of the Company's Surgical Business international sales are
in Europe.

In the United States, the Company sells its Surgical Business products through a
combination of 13 distributors and independent sales representatives managed by
the Surgical Business' regional sales managers. To further strengthen the direct
relationship between the Company and the end users of its products, the Company
requires distributors to provide the Company with the names and addresses of
such end users and the Company ships products directly to end users for a
limited period of time when there is a new product application. In addition to
strengthening customer relationships, this practice provides the Company with
some protection in the event a distributor is terminated and resists providing
the Company with customer lists.

Internationally, the Company's Surgical Business products are sold through 31
distributors. In some situations, sales in a country may occur through more than
one distributor due to distributors' varying market strengths and focus.

In fiscal 1995, three domestic distributors accounted for the following
percentages of the Surgical Business' gross revenue: Futuretech, Inc., (21%);
Cardio Medical Products, (12%); and Life Systems, Inc., (17%).  In fiscal 1994,
the Surgical Business had no single customer or distributor who accounted for
10% or more of the Surgical Business' gross revenue.  In fiscal 1993, one
domestic distributor accounted for 11% of the Surgical Business' gross revenue.

The Company currently has written agreements with 19 of its domestic and
international independent sales representatives and distributors. These
agreements generally impose limited geographic exclusivity and minimum purchase
obligations on the Company's independent sales representatives and distributors.
However, significant overlap occurs in many of the Company's international
distribution agreements. These agreements are typically terminable upon breach
of the agreement by the distributor, including breach of the minimum sales
obligations imposed by the agreement, as well as certain extraordinary events.

The Surgical Business' marketing and sales department and its national and
international distribution network is managed by the Vice President of Marketing
and Sales. The Surgical Business' marketing and sales department currently
consists of 15 employees. These employees include domestic and international
sales managers, domestic regional sales managers, product managers and customer
service personnel.

  COMPETITION

The Company's Surgical Business competes primarily on the basis of product
performance, service and price. The Company believes that product performance is
the single most important factor in selling any of its products and develops and
produces its products accordingly. The surgical products 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 Company's specific
product market, particularly in the Company's surgical tool product markets
and/or in the general field of medical devices and supplies. Broad 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 for their products, including those that compete with the
Company's 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


                                     10

<PAGE>

of purchasing functions.

The Company is not aware of any tissue or synthetic products that are
configured for use with surgical staplers in LVR surgery which compete with
PERI-STRIPS. To the best of the Company's knowledge, the FDA has not cleared
for marketing any staple line reinforcement product, other than PERI-STRIPS,
for use in LVR surgery.   To the Company's knowledge, the dural patches that
are currently available and compete with DURA-GUARD are either autologous or
are produced from processed cadaver tissue, including TutoplastTM, a
processed cadaver product manufactured by Biodynamics International, Inc. In
addition to specifically configured patches, there are multi-purpose patches
made from bovine and other types of animal tissue that compete with the
Company's SUPPLE PERI-GUARD, PERI-GUARD, and VASCU-GUARD products, including
bovine pericardium products produced by Medtronic, Inc. and Baxter
International Inc. The Company does not believe that these alternative bovine
pericardium products have specific FDA marketing clearance for use in the
lung, although such products are FDA cleared for pericardial closure and soft
tissue repair. In addition, synthetic multi-purpose patches made out of PTFE
or silicone fabric are currently available. W. L. Gore & Associates, Inc.,
manufacturer of Gore-Tex-Registered Trademark-, is believed to have a
prominent position in the synthetic patch market. Synthetic patches are
generally cheaper to produce and to the extent that comparable synthetic
patches are available and effective in procedures, the Company faces
significant price competition for its Tissue-Guard products. The Company
believes, however, that the collagen characteristics exclusive to tissue, the
special configuration of its Tissue-Guard products and the proprietary
tissue-fixation technology (SUPPLE PERI-GUARD, PERI-STRIPS, DURA-GUARD and
VASCU-GUARD) and patented (PERI-GUARD) tissue-fixation technology employed by
the Company offer significant product performance advantages over competing
products.

Alternative treatments and competitive products to BIOGRAFT include drug
therapies and surgical procedures that use autologous or synthetic grafts.
Once the decision has been made to use surgical intervention, surgeons
generally prefer the patient's own vessels for lower limb vascular
reconstruction. When the patient's own vessels are not available in
sufficient quality or quantity, surgeons choose a prosthesis graft such as
BIOGRAFT or synthetic grafts made from expanded PTFE produced by W. L. Gore &
Associates, Inc., IMPRA, Inc. or other grafts made of bio-synthetic materials.

MANUFACTURING

The Company manufactures all of its Surgical Business products except the
BIO-VASCULAR PROBE at its St. Paul, Minnesota facility. In July 1995, the
Company moved to a new 36,000 square foot facility, which more than doubled
its total space and nearly quadrupled its manufacturing capacity. The Company
acquires bovine pericardium for use in the Tissue-Guard product line from a
private independent contractor who obtains the tissue from local United
States Department of Agriculture inspected meat packing facilities. The
Company acquires human umbilical cords for use in BIOGRAFT from various
hospitals throughout the United States.  The Company has not experienced any
product shortages arising from interruptions in the supply of any raw
materials or components, and has identified alternative sources of supply for
such raw materials and components.

The BIO-VASCULAR PROBE is manufactured to the Company's specifications by a
contract manufacturer, with certain final cleaning, packaging and
sterilization testing procedures performed by the Company at its St. Paul
facility. While the Company has not experienced any interruption in supply of
this product to date, it has not identified any alternative source of supply
and any significant interruption in supply of this product in the future
could have an adverse effect on the Company's sales of the BIO-VASCULAR PROBE.

MEDICAL IMAGING SOFTWARE BUSINESS

GENERAL. The Medical Imaging Software Business develops and markets 3-D
volume imaging software products for the visualization and analysis of
imaging data for medical applications. The Medical Imaging Software Business
is conducted through the Company's wholly-owned subsidiary, Vital Images,
which was acquired in May 1994. Prior to its acquisition by the Company,
Vital Images also developed and produced 3-D volume imaging software for use
in geoscience applications.  In August 1995, the Company granted an
exclusive, perpetual source code license to CogniSeis for the

                                    -11-

<PAGE>

Company's geoscience product which focused the Company exclusively  on
medical applications for its software technology. See "Management's
Discussion and Analysis of Results of Operations and Financial
Condition--Overview" on page 28 of this Report.

The Company's Medical Imaging Software Business is continuing development of
VOXELVIEW, the first product developed by Vital Images for medical
applications. VOXELVIEW provides complete and accurate 3-D rendering of data
collected by advanced medical imaging devices such as spiral CT scanners, MRI
imaging devices, PET scanning devices, and ultrasound devices. The 3-D images
rendered by VOXELVIEW are intended to enhance the ability of radiologists,
surgeons and other physicians to screen for specific pathologies, diagnose
pathological conditions and plan surgical procedures.

INDUSTRY BACKGROUND. The use of CT scan, MRI, PET and Ultrasound is
widespread in the U.S. medical community and, to a lesser extent, in other
industrialized countries. CT scan, MRI, PET and Ultrasound capture and record
digital information describing the dimensions and properties of scanned
objects. Historically, these imaging devices produced digital output in a
variety of proprietary formats. The imaging scanner manufacturers have now
adopted an international standard called DICOM3 that greatly simplifies the
process of using a VOXELVIEW-powered workstation in conjunction with the
latest generation of imaging systems.  In the United States, the market for
CT and MRI scanners has evolved as scanners with higher resolution and faster
data acquisition have been developed.  VOXELVIEW 's value to the end-user
increases with the speed and greater sophistication of the imaging equipment
in use.

While the number of imaging devices used in hospitals and clinics is large,
the use of 3-D rendering of imaging data collected by such devices has been
exploited primarily by leading medical institutions. Until now, the
workstations required to run 3-D volume visualization software were very
expensive, limiting the number of institutions which could afford them.
Additionally, the number of images that was able to be captured was low
enough that diagnosis could be done by viewing only 2-D slices. Recent
enhancements in scanner technology yield a greater number of images in much
more detail, which can only be efficiently "read" when rendered in 3-D. The
Company believes that its volume rendering technology will be more effective
in analyzing data than the mathematically modeled "surface rendering"
approach used by others.

PRODUCTS AND PRODUCT DEVELOPMENT.  VOXELVIEW is an interactive, volume
imaging and analysis software system designed to accept large volumes of data
from any medical digital imaging technology, manipulate the data at high
speeds and display it in accurate 3-D images. VOXELVIEW is based upon a high
speed volume renderer, the Voxel Engine, which can image volume data at a
speed which permits "real-time" viewing of data sets. VOXELVIEW has been
designed to enhance the ability of radiologists, surgeons and other
physicians to screen for specific pathologies, diagnose pathological
conditions and plan surgical procedures. The Company has licensed VOXELVIEW
software packages to approximately 80 medical and research institutions as a
research tool. Currently, VOXELVIEW only operates on high-speed
graphics-oriented work stations marketed by Silicon Graphics, Inc. ("Silicon
Graphics").

The Company recently completed development of VOXELVIEW 2.5, an updated and
improved version of VOXELVIEW. The Company is developing VOXELVIEW 2.5 so
that it can be marketed to a broader group of medical institutions.  Versions
of VOXELVIEW will (i) improve the product's interface qualities and make it
more user-friendly, and (ii) enable the product to operate on work stations
manufactured by companies other than Silicon Graphics, and be directed
towards specific applications.  In December 1995, the Company received notice
of clearance from the Food and Drug Administration ("FDA") to market
VOXELVIEW as a clinical diagnostic and surgical planning device when used in
conjunction with CT and MRI image data.  The Company has also adopted the
industry standard graphics language, OpenGL-Registered Trademark-, which
should enable the Company's products to operate on hardware platforms
manufactured by companies such as Hewlett-Packard Company and IBM. There can
be no assurance that the Company will be able to successfully commercialize
VOXELVIEW 2.5.

The Company has also developed a modular enhancement to VOXELVIEW called
VOXEL ANIMATOR, which allows the user to create "fly throughs." A "fly
through," for example, would allow a radiologist to perform virtual
endoscopies by navigating through the 3-D data of patients' blood vessels
and/or organs to detect disease. This technology is designed to assist the
physician in lowering patient risk and diagnostic cost and achieving better
surgical outcomes.

                                    -12-

MARKETS.  Having received notice of FDA clearance to market VOXELVIEW in
December 1995, the Company is currently finalizing the marketing plan for
this product.  The Company intends initially to target 250 of the largest
academic medical institutions and an additional 300 tertiary care
institutions.  As the price of high speed workstations decrease, the
marketing focus will be expanded to a broader audience of medical
institutions.

The Medical Imaging Software Business plans to continue its strategy of
direct marketing within the United States while using distributors and other
marketing partners internationally.  The Company also has an OEM agreement
with Precision Therapy, Inc. (""PTI"), a leading supplier of radiation
treatment planning systems, under which the Company has granted PTI an
exclusive license for the use of a portion of VOXELVIEW technology for use as
a tool in radiation planning therapy.  To date, revenue from this agreement
has not been material.  The Company intends to seek other advantageous OEM
and third party relationships that will increase its ability to reach
attractive markets.

RESEARCH AND DEVELOPMENT.  The majority of the Medical Imaging Software
Business' employees are engaged in research and development. The Company also
collaborates with researchers at several universities and maintains close
ties with lead engineering groups at Silicon Graphics. The Company is
currently concentrating its research and development efforts on improving
VOXELVIEW as a medical diagnostic tool, including working on refinements that
will increase clinical applications of VOXELVIEW by improving human interface
qualities, making the product more user-friendly.  The Company spent
$1,357,000, $1,255,000 and $719,000 on research and development in the
Medical Imaging Software Business in fiscal 1995, 1994 and 1993,
respectively.  In addition, the Company recognized revenues of  $115,220,
$105,050 and $122,250 in fiscal 1995, 1994 and 1993 with regard to customer
sponsored research and development.  For information about Company-wide
research and development expenses, see the Consolidated Financial Statements
on page 39 of this Report.

COMPETITION.  The medical digital imaging market in which the Company
competes is characterized by intense competition. This market is dominated by
established manufacturers of imaging equipment that have broader product
lines, greater distribution capabilities, substantially greater capital
resources and larger marketing, research and development staffs and
facilities than the Company. The Company competes with major imaging
equipment vendors, such as GE Medical Systems, Picker International  Inc. and
Siemens AG, who currently offer 3-D rendering or will do so in the near
future. These large equipment vendors have an entrenched position in major
radiology departments and significantly greater marketing resources than the
Company. In addition, the Company competes with other medical imaging
software developers, including ISG, Inc. and Cemax, Inc., which offer
competing after-market software for medical imaging and these competitors
currently have greater marketing and distribution resources and capabilities
than the Company.

The Company competes primarily in two ways. First, the Company specializes in
direct volume rendering technology and has developed a high level of
expertise in the effective implementation of this technology, resulting in
much higher levels of data fidelity than other 3-D methods used in medical
applications. Second, the Company has developed a unique feature of its
imaging software, VOXEL ANIMATOR, allowing a user to conduct "fly through"
examinations similar to a virtual reality environment. The Company believes
that no competitor has developed this "fly through" capability.

GOVERNMENTAL REGULATION

The manufacture and sale of the Company's surgical and medical imaging
products 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 contained in the Safe Medical Devices Act of 1990. The Company is
subject to the standards and procedures respecting 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.

These regulations classify medical devices as either Class I, II or III
devices, which are subject to general controls, special controls or premarket
approval requirements, respectively. All Class I and II devices as well as
some Class III devices marketed prior to the effective date of the Medical
Device Amendments of 1976 can be cleared for marketing pursuant to

                                    -13-

<PAGE>

a 510(k) pre-market notification, establishing that the device is
"substantially equivalent" to a device that was legally marketed prior to
May 28, 1976, the date on which the Medical Device Amendments of 1976 became
effective. The 510(k) pre-market notification must be supported by data
establishing the claim of substantial equivalence to the satisfaction of the
FDA. The process of obtaining a 510(k) clearance typically can take several
months to a year or longer. If substantial equivalence cannot be established,
or if the FDA determines that the device or the particular application for
the device requires a more rigorous review, the FDA will require that the
manufacturer submit a PMA application that must be carefully reviewed and
approved by the FDA prior to sale and marketing of the device in the United
States. The PMA application must contain the results of clinical trials, the
results of all relevant prototype tests, laboratory and animal studies, a
complete description of the device and its components, and a detailed
description of the methods, facilities and controls used for manufacturing,
including the method of sterilization and its assurance. In addition, the
submission must include the proposed labeling, advertising literature and
training methods, if applicable. Most Class III devices are subject to the
PMA requirements rather than the 510(k) pre-market notification procedure.
The process of obtaining a PMA can be expensive, uncertain and lengthy,
frequently requiring anywhere from one to several years from the date of FDA
submission, if approval is obtained at all. Moreover, a PMA, if granted, may
include significant limitations on the indicated uses for which a product may
be marketed. FDA enforcement policy strictly prohibits the marketing of
approved medical devices for unapproved uses. In addition, product approvals
can be withdrawn for failure to comply with regulatory standards or the
occurrence of unforeseen problems following initial marketing.

Of the Company's current products, BIOGRAFT and PERI-GUARD (when marketed as
a pericardial patch) are Class III devices. BIOGRAFT received marketing
clearance from the FDA pursuant to a PMA, while PERI-GUARD received clearance
for use as a pericardial patch as the result of a 510(k) submission.
PERI-STRIPS (as marketed in both strip and sleeve configurations),
VASCU-GUARD, DURA-GUARD, PERI-GUARD (when marketed as a patch for soft tissue
deficiency), SUPPLE PERI-GUARD (when marketed as a patch for soft tissue
deficiency and as a pericardial patch) and both the disposable and reusable
FLO-RESTER and the BIO-VASCULAR PROBE have all been classified as Class II
medical devices and have received 510(k) marketing clearance from the FDA.
The Company's Medical Imaging Software  VOXELVIEW 2.5 is also a Class II
medical device which received notice of market clearance in December 1995.

Both the United States and Europe have recently focused attention on the
safety of tissue banks, spurred by incidents of the transmission of human
disease during tissue transplantation. In the United States, recent FDA draft
regulations have outlined requirements for tissue banks. The legislation has
specifically excluded medical devices subject to FDA review, including
preserved umbilical cord vein grafts such as BIOGRAFT. As a result, the
Company does not expect BIOGRAFT to be subject to tissue bank regulations in
the United States, including the expensive donor screening and donor testing
procedures. In response to the increased scrutiny of umbilical cord vein
grafts, the Company commissioned an independent virology laboratory to test
BIOGRAFT for viral inactivation. The results of the testing demonstrated that
BIOGRAFT'S chemical manufacturing processes inactivate a variety of viruses,
resulting in a sterile product. The Company has informed the FDA of these
test results and does not anticipate that the FDA will impose additional
regulatory requirements on BIOGRAFT. There can be no assurance, however, that
the FDA will not impose additional regulatory requirements on BIOGRAFT at
some later date or that BIOGRAFT would be able to meet any such new
requirements.

The Company is also subject to regulation in most 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. In Japan, a potentially significant market for the Company's
products, clinical trials of certain of the Company's products are required
before such products can be cleared for sale in the Japanese market. To date,
this has delayed the Company's market entry in some cases, but has not
ultimately prevented sales in Japan of any of the Company's devices sold in
the United States. The Company relies on its independent distributors to
comply with the majority of the foreign regulatory requirements, including
registration of the Company's products with the appropriate governmental
authorities. To date, the Company has been successful in complying with the
regulatory requirements in most foreign countries in which its products are
marketed, although the responsible authorities in France have raised concerns
regarding the Company's products produced from bovine tissue. If France
prohibits sales of Tissue-Guard products, it is not expected

                                    -14-
<PAGE>

to have a material adverse effect on the Company. Although the Company does
not anticipate that any other EU countries will prohibit the sale of
Tissue-Guard products, such prohibition by certain EU countries could have a
material adverse effect on the Company's business, financial condition and
results of operation.

The Company is subject to periodic inspections by the FDA, whose primary
purpose is to audit the Company's compliance with good manufacturing
practices ("GMP") established by the FDA and other applicable government
standards. 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 regulations.

The Company's new manufacturing facilities and processes are also undergoing
an inspection and audit process by the British Standards Institute ("BSI")
in conjunction with the Company's efforts to achieve compliance with the
requirements of the MDD issued by the EU. The BSI is the "Notified Body"
that the Company has selected to verify that the Company's quality system
conforms with the ISO 9001 international quality standard and that its
products conform with the "essential requirements" set forth by the MDD for
the class of products produced by the Company. Certification by BSI of
conformity with both the ISO 9001 standard and the MDD essential requirements
would enable the Company to prepare a Declaration of Conformity supporting
the placement of the "CE" mark on the Company's products. The CE mark would
enable the Company's products to be marketed, sold and used throughout 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 June 15, 1998, when all of the Company's current products
(and those of its competitors) will be required to comply with the essential
requirements in order to be marketed in the EU. BSI completed a
pre-assessment of certain of the Company's facilities and processes in May
1995, identifying areas requiring a moderate degree of modification to comply
with the essential requirements. A second pre-assessment focusing on other
aspects of the Company's operations was completed in October 1995, and a
final assessment has been tentatively scheduled for April 1996. Authority to
prepare a Declaration of Conformity will require the successful completion of
a final audit by BSI and submission and clearance of a dossier on each of the
Company's products, demonstrating compliance with the essential requirements
of the MDD. The Company believes that these steps will be completed by the
summer of 1996, although there can be no assurance that the Company will be
successful in receiving certification by BSI.

The future regulatory environment for BIOGRAFT in Europe is unclear. The MDD
explicitly excludes from coverage medical devices derived from human tissue;
however, certain European medical device manufacturers are actively lobbying
for the re-inclusion of such devices in the MDD. If this effort is
successful, the earliest date for applying for CE mark approval for BIOGRAFT
is expected to be 1998. In addition, if extensive donor screening and donor
testing requirements are imposed, such requirements could make it
uneconomical to sell BIOGRAFT in Europe even under the CE mark. As a result
of significant problems with their blood supply, France has passed national
laws and regulations requiring extensive donor screening and testing on
products derived from human tissue. Accordingly, BIOGRAFT is not being sold
in France. It is not known whether a CE mark for BIOGRAFT would override such
national requirements or whether other countries in the EU will adopt
regulations similar to those of France. The Company is seeking BIOGRAFT
registration in Germany, but cannot predict when or if it will achieve such
registration. BIOGRAFT is not marketed generally in Germany, but rather is
prescribed by physicians on a prescription-by-prescription basis. If the CE
mark is unavailable for BIOGRAFT or if the requirements for obtaining a CE
mark are too burdensome, the Company will seek country-by-country
registration of the product where such registration requirements exist. The
Company cannot predict when or if it would obtain such registrations.

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

                                    -15-

<PAGE>

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 an adverse impact on the Company's business, financial
condition and results of operations.

THIRD PARTY REIMBURSEMENT AND COST CONTAINMENT

The Company's surgical products are purchased primarily by hospitals and
other users which then bill various third-party payors for the services
provided to the patients. These payors, which include Medicare, Medicaid,
private health insurance plans and managed care organizations, reimburse part
or all of the costs and fees associated with the procedures utilizing the
Company's products. Through fiscal 1995, the Company's medical imaging
products have been purchased by a limited number of medical and research
institutions for research applications and have, therefore, not been subject
to reimbursement issues.

The availability and level of reimbursement from third-party payers is
significant to the Company's business.  For Medicare carriers, the United
States Healthcare Finance Administration ("HCFA"), an agency of the federal
government, establishes a national coverage policy, including the amount to
be reimbursed, for coverage of claims submitted for reimbursement related to
a specific procedure.  Private health insurance plans and managed care
organizations make their own determinations regarding coverage and
reimbursement based either upon ""usual and customary" fees or,
increasingly, upon a similar prospective payment system.

During the past several years, the major third party payers have
substantially revised their reimbursement methodologies in an attempt to
contain their healthcare reimbursement costs.  Medicare and Medicaid
reimbursement for inpatient hospital services is based on a fixed amount per
admission based on the patient's specific diagnosis.  As a result, any
illness to be treated or procedure to be performed will be reimbursed only at
a prescribed rate set by the government that is known in advance to the
healthcare provider.  If the treatment costs less, the provider keeps the
difference.  If it costs more, the provider cannot bill the patient for the
rest.  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.  No separate payment is made in most cases for products such as
the Company's when they are furnished or used in connection with inpatient
care.  Any amendments to existing 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 an 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 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


                                  16

<PAGE>

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 these
practices, the existing or proposed legislation, or such third-party payor
measures may have on its future business, financial condition or results of
operations.

Because the Company's surgical products are primarily used in thoracic,
cardiac, neuro and vascular surgeries, changes in reimbursement policies and
practices of third party payors with respect to these surgeries could have a
substantial and material impact on sales of the Company's products. The
development or increased use of more cost effective treatments for diseases
requiring these surgeries could cause such payors to decrease or deny
reimbursement for such surgeries or to favor these other treatments over
surgical treatment.

Recent developments concerning reimbursement of LVR surgery are likely to
have a material adverse effect on the Company's business and results of
operations. Generally, Medicare had been reimbursing hospitals and surgeons
for LVR surgery since the procedure was re-introduced in 1994.  LVR surgery
uses PERI-STRIPS, the product which has been primarily responsible for the
Company's growth in net revenue and net income in recent periods (see
"Surgical Business--Markets and Medical Need, Lung Volume Reduction Surgery"
on page 3 of this report). Recently, HCFA decided that it did not have enough
patient follow-up data to substantiate the safety and efficacy of LVR
surgery.  On that basis, HCFA decided to cease reimbursement of LVR surgery
until its technical assessment committee ("TAC") could complete an evaluation
of the safety and efficacy of the procedure.  TAC has set February 13, 1996
as the final date for surgeons to submit patient data.  It is reasonably
expected that once the data is received by TAC any decision regarding
reimbursement will take, at a minimum, two months and possibly a year or
more.  HCFA's decision to deny reimbursement for LVR surgery is expected to
have a material adverse effect on the Company's net revenue and net income at
a minimum in the first and second quarters of fiscal 1996, and may continue
to have such an effect in future periods.  While the Company believes, based
on reported outcomes, that HCFA will eventually approve reimbursement for LVR
surgery, the Company cannot say with any certainty when, or if, the
reimbursement of LVR surgery will be approved.  The Company believes that LVR
procedures reimbursed by Medicare constitute over 50% of total LVR
procedures.  While the Company understands that private insurance companies
and managed care organizations (which the Company believes have been the
third-party payors responsible for a significant percentage of reimbursed LVR
procedures) are currently reimbursing LVR surgery based on their own
evaluation of the procedure and its outcomes, it is unknown whether these
private payors will change their reimbursement practices in light of HCFA's
decision.  See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Comparison of the Year Ended October 31, 1995 with
the Year Ended October 31, 1994, Net Revenue" on page 30 of this Report.)

INTELLECTUAL PROPERTY

The Company's success will depend in large part on its ability to preserve
its trade secrets, to obtain patent protection for its products and to
operate without infringing the proprietary rights of third parties. While the
Company has obtained or acquired a license to certain patents and applied for
additional United States and foreign patents covering certain aspects of its
products, no assurance can be given that any additional patents will be
issued, that the scope of any patent protection will exclude competitors or
that any of the Company's rights under such patents will be held valid if
subsequently challenged. The validity and breadth of claims covered in
medical technology patents involve complex legal and factual questions and
therefore may be highly uncertain. Whether or not the Company's patent
applications are granted, others may receive patents which contain claims
having a scope that covers products developed by the Company.

In July 1995, the Company received notice of allowance of a United States
patent which relates to the use of tissue on a removable backing and covers
the sleeve configuration of PERI-STRIPS. In connection with this same
application, the Company has filed divisional patent applications relating to
the combination of tissue with a surgical stapling gun and methods of
performing a surgical procedure to remove diseased tissue. There can be no
assurance that these divisional patent applications will be granted. Other
than the notice of allowance of a patent on the sleeve configuration of
PERI-STRIPS, the Company holds no patents and pays no royalties on SUPPLE
PERI-GUARD or the configurations of SUPPLE PERI-GUARD marketed as DURA-GUARD
or VASCU-GUARD.  In December 1994, the Company entered into an agreement with
Surgical Research, Inc.,  which obligates the Company to pay royalties of
five percent (5%) on net revenue from sales of PERI-STRIPS for the life of


                                     17

<PAGE>

any patents, if any are issued, or for seven years.  In December 1995, the
Company purchased the patent for PERI-GUARD.  Previously, the Company had an
exclusive, worldwide, perpetual license to make, use and sell its PERI-GUARD
product for use in connection with the cardiovascular system.  The Company
also has an exclusive, worldwide, perpetual license to make, use and sell its
FLO-RESTER product.  The last of the patents related to the Company's
BIOGRAFT product expired in November 1993.

In its Surgical Business, 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.
SUPPLE PERI-GUARD, which is used in the manufacture of the majority of the
Company's Tissue-Guard products, is protected exclusively by trade secrets.
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.

In its Medical Imaging Software Business, the Company relies on a combination
of license agreements, contracts, confidentiality agreements and trade
secrets to establish and protect its proprietary rights in its technology.
The Company distributes its products under software license agreements that
grant customers licenses to use, rather than ownership of, the software. The
Company also employs encryption technology to prevent the use of its software
on work stations that have not been specifically designated by the Company.
Effective copyright and trade secret protection may be unavailable or limited
in certain foreign countries. In September 1988, the Company acquired the
exclusive perpetual license to use, further develop and market the technology
underlying VOXELVIEW on a worldwide basis.

The surgical products and medical imaging industries are characterized by
frequent and substantial intellectual property litigation, and competitors
may resort to intellectual property litigation as a means of competition. The
surgical products and medical imaging markets are characterized by extensive
patent and other intellectual property claims that can create greater
potential than in less developed markets for possible allegations of
infringement, particularly with respect to newly developed technology.
Intellectual property litigation is complex and expensive, and the outcome of
such litigation is difficult to predict. 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.
Litigation may also be necessary to enforce patents issued to and licenses
held by the Company, to protect trade secrets or know-how owned by the
Company or to determine the enforceability, scope and validity of the
proprietary rights of others. An adverse determination in any such proceeding
could subject the Company to significant liabilities to third parties, or
require the Company to seek licenses from third parties or pay royalties that
may be substantial. Furthermore, there can be no assurance that necessary
licenses would be available to the Company on satisfactory terms, if at all.
Accordingly, an adverse determination in a judicial or administrative
proceeding or failure to obtain necessary licenses could prevent the Company
from manufacturing or selling certain of its products which in turn would
have a material adverse effect on the Company's business, financial condition
or results of operations.

The Company has registered United States trademarks, including PERI-STRIPS,
VASCU-GUARD, PERI-GUARD,  BIOGRAFT, FLO-RESTER, VOXELVIEW and VOXELGEO.

EMPLOYEES

At January 3, 1996, the Company, including its wholly-owned subsidiary,
employed 123  full-time and two part-time individuals, including 18 in
research and development, 61 in manufacturing, 18 in sales and marketing, 25
in general and administrative functions and three in regulatory affairs. The
Company's employees are not represented by a union, and the Company considers
its relationship with its employees to be good.

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.

HISTORY OF LOSSES; UNCERTAIN PROFITABILITY PROSPECTS

The Company has experienced a net loss during each of the three years in the
period ended October 31, 1994, although the Surgical Business has had
operating income for each of these years.  The imaging business has incurred
losses since 1990, and the Company does not expect that the Medical Imaging
Software Business will be profitable in the near term.  While the Company was
profitable in the year ended October 31, 1995, there can be no assurance that
the Company will continue to be profitable in the near term or at any time in
the future.  The Company's profitability in the near term and the foreseeable
future will depend upon the continued success of PERI-STRIPS, of which there
can be no assurance. See "Important Factors - Limitations on Third-Party
Reimbursement" below.

LIMITATIONS ON THIRD-PARTY REIMBURSEMENT

The Company's products are purchased primarily  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.
Payors may deny reimbursement if they determine that a product used in a
procedure was not used in accordance with established Payor protocol
regarding cost-effective treatment methods or was used for an unapproved
indication.

Third-party payors are also increasingly challenging the prices charged for
medical products and services and, in some instances, have put pressure on
medical device 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 surgical
procedures in which the Company's products are used will continue to be
considered cost-effective by third-party payors, that reimbursement for such
surgeries or imaging services will be available or, if available will
continue, or that payors' reimbursement levels will not adversely affect the
Company's ability to sell its products on a profitable basis.  The Company's
medical imaging products have been purchased to date by a limited number of
medical and research institutions for research applications.  The cost of
health care has risen significantly over the past decade, and there have been
and may continue to be proposals by legislators, regulators and third-party
payors to curb these costs.  Failure by hospitals and other users of the
Company's products to obtain reimbursement from third-party payors, changes
in third-party payors' policies towards reimbursement for procedures using
the Company's products or legislative action could have a material adverse
effect on the Company's business, financial condition and results of
operations.

For Medicare carriers, the U.S. Healthcare Finance Administration ("HCFA")
establishes a national coverage policy, including the amount to be
reimbursed, for coverage of claims submitted for reimbursement related to a
specific procedure.  Recent developments concerning reimbursement of LVR
surgery are likely to have a material adverse effect on the Company's
business and results of operations.  Generally, Medicare had been reimbursing
hospitals and surgeons for LVR surgery since the procedure was re-introduced
in 1994.  LVR surgery uses PERI-STRIPS, the product which has been primarily
responsible for the Company's growth in net revenue and net income in recent
periods (see "Surgical Business--Markets and Medical Need, Lung Volume
Reduction Surgery" on page 3 of this report).  Recently, HCFA decided that it
did not have enough patient follow-up data to substantiate the safety and
efficacy of LVR surgery.  On that basis, HCFA decided to cease reimbursement
of LVR surgery until its technical assessment committee ("TAC") could
complete an evaluation of the safety and efficacy of the procedure.  TAC has
set February 13, 1996 as the final date for surgeons to submit patient data.
It is reasonably expected that once the data is received by TAC any decision
regarding reimbursement will take, at a minimum, two months and possibly a
year or more.  HCFA's decision to deny reimbursement for LVR surgery is
expected to have a material adverse effect on the Company's net revenue and
net income at a minimum in the first and second quarters of fiscal 1996, and
may continue to have such an effect in future periods.  While the Company
believes, based on reported outcomes, that HCFA will eventually approve

                                     19

<PAGE>

reimbursement for LVR surgery, the Company cannot say with any certainty
when, or if, the reimbursement of LVR will be approved.  The Company believes
that LVR procedures reimbursed by Medicare constitute over 50% of total LVR
procedures.  While the Company understands that private insurance companies
and managed care organizations (which the Company believes have been the
third-party payors responsible for a significant percentage of reimbursed LVR
procedures) are currently reimbursing LVR surgery based on their own
evaluation of the procedure and its outcomes, it is unknown whether these
private payors will change their reimbursement practices in light of HCFA's
decision.  See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Comparison of the Year Ended October 31, 1995 with
the Year Ended October 31, 1994, Net Revenue" on page 30 of this Report and
"Third Party Reimbursement and Cost Containment" on page 16 of this report.

DEPENDENCE ON LUNG VOLUME REDUCTION PROCEDURE

The growth in revenue and profitability of the Company in fiscal 1995 as
compared to fiscal 1994 was primarily due to increased sales of PERI-STRIPS.
PERI-STRIPS accounted for approximately 41% of the Company's net revenue for
the year ended October 31, 1995.  The Company believes that sales of
PERI-STRIPS will be the primary factor in revenue growth and profitability in
the foreseeable future.  This product is used primarily in lung volume
reduction ("LVR") surgery, a procedure that was abandoned 35 years ago due to
unacceptable mortality and complication rates. The LVR procedure was
re-introduced in 1994, modified and enabled by the use of a surgical stapler
in combination with the Company's PERI-STRIPS product. Due to the recent
re-introduction of the modified procedure, the number of patients who have
undergone the procedure and for whom a clinically acceptable post-operative
period of evaluation has elapsed is still relatively small. Similarly, the
number of physicians performing the procedure and from whom data is available
to the Company is small. Accordingly, there presently does not exist a
statistically meaningful body of clinical data from which to draw conclusions
concerning the efficacy and long-term outcomes associated with the LVR
procedure. The Company believes that patients who have undergone the LVR
procedure may require and additional year or more of follow-up examination
before the procedure can be properly evaluated by the medical community.  If
the LVR procedure is ultimately determined to provide only temporary benefits
or otherwise results in unfavorable or unacceptable outcomes, this would
adversely affect sales of the Company's PERI-STRIPS product and have a
material adverse effect on the Company's results of operations.  The success
of PERI-STRIPS will also depend on the acceptance of the product by surgeons
performing LVR surgery.  The Company estimates that there were approximately
700 surgeons worldwide trained to perform the LVR procedure by the end of
calendar 1995.  Although additional surgeons are being trained, the growth in
PERI-STRIPS sales has been and will continue to be closely related to the
number of surgeons trained in the LVR procedure and the willingness of such
surgeons to perform the LVR procedure.  If the number of surgeons trained and
effectively performing the LVR procedure does not grow as rapidly as the
Company anticipates, the Company's business, results of operations and
financial condition will be adversely affected.  Growth in the number of LVR
procedures performed is also dependent upon the criteria used by surgeons in
selecting patients deemed appropriate candidates for such surgery. If the
selection criteria become too rigorous, the number of LVR procedures
performed and related sales of the PERI-STRIPS product may decrease, which
would have a material adverse effect on the Company's business, results of
operations and financial condition.  See "Surgical Business--Markets and
Medical Need" on page 3 of this Report.

HIGHLY COMPETITIVE INDUSTRIES AND RISK OF TECHNOLOGICAL OBSOLESCENCE

The Company faces intense competition in both its Surgical Business and its
Medical Imaging Software Business.  The medical product and imaging
industries are highly competitive and characterized by rapid innovation and
technological change.  The Company expects technology to continue to develop
rapidly, and the Company's success will depend to a large extent on its
ability to maintain a competitive position with its technology.  There can be
no assurance that the Company will be able to compete effectively in the
marketplace or that products developed by its competitors will not render its
products obsolete or non-competitive.  Similarily, there can be no assurance
that the Company's competitors will not succeed in developing or marketing
products that are viewed by physicians as providing superior clinical
performance or are less expensive relative to the Company's products
currently marketed or to be developed. Several established companies
manufacture and sell surgical products which compete with all of the
Company's surgical products, other than PERI-STRIPS. The Company believes
that at least two established companies are developing products intended to
compete with PERI-STRIPS. The competition in the imaging industry is also
intense and consists largely of established manufacturers of imaging


                                   20

<PAGE>

equipment.  The companies with which the Company competes have greater
distribution capabilities, substantially greater capital resources and larger
marketing, research and development staffs and facilities than the Company.
In addition, many of the Company's competitors offer broader product lines
within the Company's specific product markets.  Broad product lines may give
the Company's competitors the ability to negotiate exclusive, long-term
medical product supply contracts and the ability to offer comprehensive
pricing for their products, including those that compete with the Company's
products.  By offering a broader product line in the general field of medical
products and supplies, competitors may also have a significant advantage in
marketing competing products to group purchasing organizations and managed
care organizations that increasingly seek to reduce costs.  There can be no
assurance that the Company will be able to compete effectively with such
manufacturers in either its Surgical Business or its Medical Imaging Software
Business.  See "Surgical Business--Competition" and "Medical
Imaging Software Business--Competition" on pages 10 and 13, respectively, of
this Report.

ABILITY TO MANAGE GROWTH

To support the anticipated growth due to sales of its PERI-STRIPS product,
the Company will require additional supply, manufacturing, quality assurance,
inventory management, marketing and sales capabilities.  Although the Company
is taking steps to meet these needs, there can be no assurance that the
Company will be able to secure the necessary personnel and systems
capabilities to sustain and support the current rate of growth. See
"Surgical Business--Marketing" and "Manufacturing" on pages 9
and 11, respectively, of this Report.

INTELLECTUAL PROPERTY

The Company protects its technology through trade secrets and proprietary
know-how and through patents, both owned and licensed.  The Company seeks to
protect its trade secrets and proprietary know-how through confidentiality
agreements with employees, consultants and other parties.  SUPPLE PERI-GUARD,
which is used in the manufacture of the majority of the Company's
Tissue-Guard products, is protected exclusively by trade secrets.  There can
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. There can be no assurance that
any pending or future patent applications will result in issued patents, or
that any current or future patent, regardless of whether the Company is an
owner or licensee of such patent, will not be challenged, invalidated or
circumvented or that the rights granted thereunder or under its licensing
agreements will provide a competitive advantage to the Company.  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 does not or will not infringe patents or other rights
owned by others.

The medical product industry is characterized by frequent and substantial
intellectual property litigation, and competitors may resort to intellectual
property litigation as a means of competition. Intellectual property
litigation is complex and expensive, and the outcome of such litigation is
difficult to predict.  Any future litigation, regardless of the outcome,
could result in substantial expense to the Company and significant diversion
of the efforts of the Company's technical and management personnel.
Litigation may also be necessary to enforce patents issued to the Company and
license agreements entered into by the Company, to protect trade secrets or
know-how owned by the Company or to determine the enforceability, scope and
validity of the proprietary rights of others.  An adverse determination in
any such proceeding could subject the Company to significant liabilities to
third parties, or require the Company to seek licenses from third parties or
pay royalties that may be substantial.  Furthermore, there can be no
assurance that necessary licenses would be available to the Company on
satisfactory terms, if at all. Accordingly, an adverse determination in a
judicial or administrative proceeding or failure to obtain necessary licenses
could prevent the Company from manufacturing or selling certain of its
products which in turn would have a material adverse effect on the Company's
business, financial condition and results of operations.  See "Intellectual
Property" on page 17 of this Report.

RISKS ASSOCIATED WITH HUMAN TISSUE PRODUCTS

Both the United States and Europe have recently focused attention on the
safety of tissue banks, spurred by incidents of the transmission of human
disease during tissue transplantation.  In the United States, recent
regulations drafted by the U.S. Food and Drug Administration (the "FDA")
have outlined requirements for tissue banks. The regulations have
specifically excluded from regulation medical devices subject to FDA review,
including preserved umbilical cord vein grafts such as BIOGRAFT.  As a
result, the Company does not expect BIOGRAFT to be subject to tissue bank
regulations in the United States and the related expensive donor screening
and donor testing procedures.  There can be no assurance, however, that the
FDA will not impose additional regulatory requirements on BIOGRAFT at some
later date or that BIOGRAFT would be able to meet any such new requirements.

The future regulatory environment for BIOGRAFT in Europe is unclear.  While
the Medical Device Directive ("MDD") issued by the European Union ("EU")
explicitly excludes medical devices derived from human tissue from
regulation, certain European medical device manufacturers are actively
lobbying for the re-inclusion of such devices in the MDD.  If this effort is
successful, the earliest date for applying for CE mark approval for BIOGRAFT
is expected to be 1998.  In addition, if extensive donor screening and donor
testing requirements are imposed, such requirements could make it
uneconomical to sell BIOGRAFT in Europe even under the CE mark.  BIOGRAFT
accounted for 11% and 30% of the Company's net revenue and international net
revenue, respectively, for the year ended October 31, 1995.

EARLY STAGE OF THE MEDICAL IMAGING SOFTWARE BUSINESS

The Company's imaging business incurred operating losses of  $790,000,
$1,183,000 in fiscal  1993 and 1994, respectively, and had  operating income
of $252,000 for the year ended October 31, 1995, entirely due to the
$1,500,000 one-time source code license fee for VOXELGEO, its imaging
technology for geoscience applications, which contributed $1,322,000 to
operating income (See "Managements' Discussion and Analysis of Financial
Condition and Results of Operations --Effect of One-Time Source Code
License" on page 32 of this Report). The  grant of this perpetual, exclusive
license to VOXELGEO allows the  Medical Imaging Software Business to focus
exclusively on medical applications of its imaging technology.  With this
exclusive license, the Company will no longer  be receiving revenue from
sales for these geoscience applications.  The Company does not anticipate
that expenses of the Imaging Business will decrease proportionally to this
decrease in revenue.  As a result, the Imaging Business will likely incur
operating losses in the near term.  Although the Company has received FDA
510(k) clearance to market its VOXELVIEW product as a medical product, it
does not anticipate significant revenues from its medical imaging products in
the near term as it develops its business plan for this new clinical product.
The Company expects to continue to invest significant resources in the
research and development of VOXELVIEW.  The Company believes that successful
commercialization of VOXELVIEW primarily depends upon the development of an
improved and application specific user interface.  In addition, VOXELVIEW
currently can only be used on hardware manufactured by a single manufacturer,
and therefore the VOXELVIEW product will be affected in the short-term by the
success or failure of this hardware manufacturer. Furthermore, the success of
the VOXELVIEW software currently under development will depend upon the
ability and willingness of physicians to use such 3-D software in clinical
diagnosis, surgical planning and patient screening, of which there can be no
assurance. See "Medical Imaging Software Business--Products and Product
Development" on page 12 of this Report.

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, manufacturing, labeling and record keeping procedures for medical
devices, including medical imaging software.  The process of obtaining marketing
clearance from the FDA for new products and new applications for existing
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 or


                                    22

<PAGE>

additional applications for existing products.  In addition, certain of the
Company's surgical products that are in the research and development stage
may  be subject to a lengthy and expensive pre-market approval ("PMA")
process with the FDA. 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.  Product approvals 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.  FDA
regulations depend heavily on administrative interpretation, and there can be
no assurance that future interpretations made by the FDA or other regulatory
bodies, with possible retroactive effect, will not adversely affect the
Company.  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.

Approximately 17% of the Company's net revenue in  fiscal 1995 resulted from
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 on independent distributors to comply with
these foreign regulatory requirements and communication between foreign
regulatory agencies and the Company is indirect and occurs through the
foreign distributor.  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 affect the Company's business,
financial condition and results of operations.

The new registration scheme in the EU requires that the Company's quality
system conform with the ISO 9001 international quality standard and that its
products conform with the "essential requirements" set forth by the MDD for
the class of products produced by the Company.  Compliance with these
requirements will allow the Company to issue a "Declaration of Conformity"
and apply the "CE" mark to products, allowing free sale in the EU.  While
the Company is currently undergoing a review procedure to verify compliance
with the ISO 9001 standard and the essential requirements, there can be no
assurance that the Company will obtain the CE mark in a timely manner, or at
all.  Failure to obtain the CE mark by 1998 would limit the Company's ability
to sell its products in Europe and would have a material adverse effect on
the Company's business, financial condition and results of operations.  See
"Governmental Regulation" on page 13 of this report.

EXPOSURE TO PRODUCT LIABILITY CLAIMS; RISK OF PRODUCT RECALL

The medical product industry historically has been litigious, and the
manufacture and sale of the Company's products inherently entails a risk of
product liability claims.  Since the Company's principal products are
designed to be permanently placed in the human body, production errors could
result in an unsafe product and injury to the patient.  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.  Furthermore, 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 such a recall is instituted by the
Company or required by a regulatory agency.  On one occasion in 1992, the
Company initiated a product recall to correct the mislabeling on a small
number of one of its surgical tool products.  The mislabeling did not result
in injury to any patient and did not have an adverse effect on the Company's
business, financial condition or results of operations. A product liability
claim, recall or other claim with respect to uninsured liabilities or in
excess of insured liabilities could have a material adverse effect on the
business, financial condition and results of operations of the Company.

DEPENDENCE ON DISTRIBUTOR SALES

Sales to distributors constitute a significant portion of the Company's
current business.  In the year ended October 31, 1995, three domestic
distributors accounted for an aggregate of  39% of the Surgical Business'
gross revenue, with each of such distributors accounting for in excess of 10%
of the Company's gross revenue for the period.  There can be no assurance
that the Company will be able to maintain its relationships with these
significant distributors, or, in the event of termination of any of such
relationships, that a new replacement distributor will be found.  The loss of
a significant distributor could materially adversely affect the Company's
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.  See "Surgical Business--Marketing" on
page 9 of this Report.

ITEM 2 - PROPERTIES

The Company leases approximately 36,000 square feet of office and
manufacturing space at 2575 University Avenue, St. Paul, Minnesota for use in
its Surgical Business.  The base rent of this lease, which commenced August 1,
1995 and expires July 31, 2005, is approximately $255,000 annually.  The
Company also pays apportioned real estate taxes and common costs on this
lease.

Additionally, the Company leases approximately 8,800 square feet located in
Fairfield, Iowa for use in its Medical Imaging Software Business, under a
non-cancelable operating lease which expires on June 1, 1997 and includes an
option to renew for one four-year period.  The base rent for this facility is
approximately $75,000 annually.

The Company believes that its current space is adequate for the foreseeable
future.

ITEM 3 - LEGAL PROCEEDINGS

The Company is not currently involved in any material legal proceedings.


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

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

OVERVIEW

The Company has two business segments which market products on a worldwide
basis. Its primary business is the Surgical Business, which develops,
manufactures and markets proprietary specialty medical products for use in
thoracic, cardiac, neuro and vascular surgery. The Company, through its wholly-
owned subsidiary, Vital Images, also develops, markets and supports certain
software products for interactive visualization and analysis of three
dimensional image data for medical applications. Net revenue generated by Vital
Images is derived primarily from software licensing and maintenance fees.

The Company has been in a period of significant growth, driven primarily by the
revenue contribution of its PERI-STRIPS product (part of the Tissue-Guard
product line). PERI-STRIPS, which enables LVR surgery for late-stage emphysema
patients, received marketing clearance from the FDA in May 1994 but was not
released fully to the market until late October 1994. Net revenue resulting from
sales of PERI-STRIPS increased from $685,000 for fiscal 1994 to $5,550,000 for
fiscal 1995 and comprised approximately 42% of the Company's net revenues (or
47% excluding the one-time license fee for VOXELGEO). The Company anticipated
that sales of PERI-STRIPS would continue to constitute an increasing share of
the Company's revenue.

Recent developments concerning reimbursement of LVR surgery are likely to
have a material adverse effect on the Company's business and results of
operations. Generally, Medicare had been reimbursing hospitals and surgeons
for LVR surgery since the procedure was re-introduced in 1994.  LVR surgery
uses PERI-STRIPS, the product which has been primarily responsible for the
Company's growth in net revenue and net income in recent periods (see
"Surgical Business--Markets and Medical Need, Lung Volume Reduction Surgery"
on page 3 of this report).  Recently, HCFA decided that it did not have
enough patient follow-up data to substantiate the safety and efficacy of LVR
surgery.  On that basis, HCFA decided to cease reimbursement of LVR surgery
until its technical assessment committee ("TAC") could complete an evaluation
of the safety and efficacy of the procedure.  TAC has set February 13, 1996
as the final date for surgeons to submit patient data.  It is reasonably
expected that once the data is received by TAC any decision regarding
reimbursement will take, at a minimum, two months and possibly a year or
more.  HCFA's decision to deny reimbursement for LVR surgery is expected to
have a material adverse effect on the Company's net revenue and net income at
a minimum in the first and second quarters of fiscal 1996, and may continue
to have such an effect in future periods.  While the Company believes, based
on reported outcomes, that HCFA will eventually approve reimbursement for LVR
surgery, the Company cannot say with any certainty when, or if, the
reimbursement of LVR will be approved.  The Company believes that LVR
procedures reimbursed by Medicare constitute over 50% of total LVR
procedures.  While the Company understands that private insurance companies
and managed care organizations (which the Company believes have been the
third-party payors responsible for a significant percentage of reimbursed LVR
procedures) are currently reimbursing LVR surgery based on their own
evaluation of the procedure and its outcomes, it is unknown whether these
private payors will change their reimbursement practices in light of HCFA's
decision.

To accommodate growth in its PERI-STRIPS business, the Company, beginning in
April 1994, made significant additional investments in personnel, plant and
infrastructure, including moving to a new and larger manufacturing facility
for the Surgical Business in July 1995. Further increases in all areas,
especially marketing and support personnel additions, were planned to support
anticipated PERI-STRIPS sales growth. Due to the recent re-introduction of
the modified procedure, the number of patients who have undergone the
procedure and for whom a clinically acceptable post-operative period of
evaluation has elapsed is still relatively small. Similarly, the number of
physicians performing the procedure and from whom data is available to the
Company is small. Accordingly, there presently does not exist a statistically
meaningful body of clinical data from which to draw conclusions concerning
the efficacy and long-term outcomes associated with the LVR procedure. The
Company believes that patients who have undergone the LVR procedure may
require and additional year or more of follow-up examination before the
procedure can be properly evaluated by the medical community.  In addition,
the recent HCFA decision has delayed any expected growth from PERI-STRIPS.
If LVR surgery reimbursement is not approved in the future, growth of the
proportions anticipated will not be forthcoming.  Accordingly, the rate and
pattern of growth, if any, of the PERI-STRIPS business, and its related
personnel, plant and infrastructure support requirements, are especially
difficult to predict.

The Company acquired Vital Images on May 24, 1994. The acquisition was a
"pooling-of-interests," and financial results for all reporting periods have
been restated as if Vital Images had been merged into the Company from
inception. Historically, Vital Images was engaged in developing and marketing 3-
D volume rendered, imaging software for various


                                       28
<PAGE>

disciplines and industries, but principally for confocal microscopy, other
medical research, and gas and oil exploration (the "Imaging Business"). After
the acquisition, the Company decided to exit the microscopy business due to
the limited market opportunity in microscopy and its relatively low margins.
Although the Company continues to provide support to existing microscopy
customers, it does not actively pursue new microscopy customers. At the time
of the acquisition, the largest near-term market opportunity for the Imaging
Business was the VOXELGEO product for gas and oil exploration applications.
The Company funded the research and development of the second generation of
this product, VOXELGEO 2.0, in order to generate revenue to fund future
development of clinical medical applications of the imaging software.  In the
process of developing VOXELGEO 2.0, the Company rewrote the entire code of
its core 3-D volume rendering technology.  A significant portion of all of
the Company's 3-D volume rendered imaging software results from certain "core
technology," and therefore improvements or changes to this "core technology"
advance all applications of the software. In order to conserve resources and
receive the benefit of industry expertise, the Company entered into a global
marketing alliance in August 1994 with CogniSeis Development, Inc.
("CogniSeis"), a company with complementary software technologies for gas and
oil exploration and an established presence in the industry. Under the
agreement, CogniSeis assumed exclusive marketing and customer support
responsibilities for VOXELGEO in exchange for 50% of software license and
maintenance fee revenue.

Subsequently, in order to concentrate the Imaging Business on medical
applications, the Company entered into a source code license agreement in
August 1995 with CogniSeis, granting it a worldwide, perpetual, exclusive
license for use in gas and oil exploration applications. Under this
agreement, CogniSeis became both the exclusive developer and exclusive
marketer of VOXELGEO. Pursuant to this agreement, the Company received a
license fee payment of $1.5 million in September 1995, which was recorded as
revenue in the fourth quarter of fiscal 1995.  The agreement further provides
for the payment to the Company on a quarterly basis of royalties based upon
the receipt of revenues generated by VOXELGEO, which payments, if any, the
Company anticipates will begin in calendar 1997. Royalties will terminate
upon the earlier of March 31, 2001 or the aggregate payment of $2.0 million
in royalties.

The Company's Imaging Business is now dedicated to the development of medical
applications of its imaging technology. Excluding the one-time source code
license fee discussed above, the Company anticipates that its Imaging
Business revenue will continue to decrease in the near term due to declining
microscopy revenue and no additional VOXELGEO revenue until 1997, when
royalties on VOXELGEO are anticipated to begin. Microscopy and gas and oil
exploration revenue accounted for more than 70% of the Imaging Business
revenue during 1993 and 1994 and, including the license fee payment of $1.5
million, approximately 82% of such revenue in fiscal 1995.  In addition, the
Company does not anticipate that expenses of the Imaging Business will
decrease, as the Company intends to continue to invest in VOXELVIEW.  The
Company recently received FDA 510(k) clearance to market its VOXELVIEW
product as a medical product.  The Company is currently finalizing the
marketing plan for this product, and does not anticipate significant revenues
from its medical imaging products in the near term.

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

  NET REVENUE

Net revenue increased 101% to $13,320,000 for fiscal 1995 from $6,632,000 for
fiscal 1994.  Net revenue of the Surgical Business increased 111% to $10,426,000
in fiscal 1995 from $4,952,000 for fiscal 1994, substantially due to increases
in sales of PERI-STRIPS, which increased to $5,550,000 in fiscal 1995 from
$685,000 for fiscal 1994 and accounted for 53% and 14% of the Surgical Business'
net revenue in fiscal 1995 and 1994, respectively.

HCFA's recent decision to deny Medicare reimbursement for LVR surgery, which
uses PERI-STRIPS to prevent air leaks, is expected to have a material adverse
effect on the Company's net revenue and net income at a minimum in the first
and second quarters of fiscal 1996, and may continue to have such an effect
in future periods.  While the Company believes, based on reported outcomes,
that HCFA will eventually approve reimbursement for LVR surgery, the Company
cannot say with any certainty when, or if, the reimbursement of LVR will be
approved.  While the Company understands that private insurance companies and
managed care organizations are currently reimbursing LVR surgery based on
their own evaluation of the procedure and its outcomes, it is unknown whether
these private payors will change their reimbursement practices in light of
HCFA's decision.  See "Third Party Reimbursement and Cost Containment" on
Page 16 of this Report and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Overview" on page 28 of this Report.

                                       30

<PAGE>

Net revenue from sales of other products of the Tissue-Guard product line,
DURA-GUARD, VASCU-GUARD, SUPPLE PERI-GUARD and PERI-GUARD, increased by 86%
to $1,846,000 for fiscal 1995 from $990,000 for fiscal 1994.  DURA-GUARD,
which was cleared to market by the FDA in June 1995, accounted for 42% of
this increase. The Company believes that heightened visibility in the
surgical community was the other significant factor in the increase in
revenues from sales of the other products in the Tissue-Guard product line.

Net revenues from sales of  BIOGRAFT decreased by 21% to $1,198,000 for
fiscal 1995 from $1,525,000 for fiscal 1994.  BIOGRAFT revenue has been
decreasing since late fiscal 1993.  The Company believes that the revenue
decrease is a result of a trend towards non-surgical intervention for
peripheral vascular obstruction and the higher price of BIOGRAFT when
compared to synthetic grafts. The Company has implemented a BIOGRAFT training
program for surgeons in an effort to improve sales of this product.

Net revenue from sales of surgical productivity tools (FLO-RESTER and the
BIO-VASCULAR PROBE) increased 7% for fiscal 1995 when compared to fiscal
1994.  The Company believes that sales of these products will not increase
materially from current levels in the foreseeable future.

Net revenue of the Imaging Business increased 72% to $2,894,000 for fiscal
1995 from $1,680,000 for fiscal 1994, due almost entirely to the one-time
$1,500,000 VOXELGEO source code license fee received in the fourth quarter of
fiscal 1995. It is expected that revenues from the Medical Imaging Software
Business will decrease in the near-term as a result of  the Company's
decision not to actively pursue new customers in the microscopy market and
the loss of revenue from VOXELGEO until 1997, when payment of royalties is
anticipated to begin.

GROSS MARGIN

The gross margin percentage increased to 71% of net revenue for fiscal 1995
from 63% of net revenue for fiscal 1994.  Gross margin percentages of the
Surgical Business were 67% and 61% for fiscal 1995 and 1994, respectively.
The vast majority of gross margin improvement in the Surgical Business was
due to changes in product mix as a result of the large volume of PERI-STRIPS
sales and the spreading of overhead costs over a larger volume of production.
 Improvement in productivity related to the manufacture of PERI-STRIPS also
contributed to the improvement.  Gross margin percentages of the Imaging
Business were 87% and 70% for fiscal 1995 and 1994, respectively.  The gross
margin percentage of the Imaging Business was positively impacted by the
VOXELGEO source code license transaction, which contributed $1,322,000 to the
gross margin.  The Company believes that future gross margin percentages for
the Medical Imaging Software Business will be a function of the developing
business model for the Medical Imaging Software Business, but are currently
expected to remain above 80%.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expense increased 42% to $5,013,000 for
fiscal 1995 from $3,541,000 for fiscal 1994, but decreased as a percent of
net revenue between comparable periods to 38% from 53%.  The increase in
expense was attributable entirely to the Surgical Business and the increases
in personnel and related overhead required to support the  revenue growth.
The Surgical Business and the Imaging Business accounted for 83% and 17%,
respectively, of these expenditures for fiscal 1995, as compared to 69% and
31%, respectively, of these expenditures for fiscal 1994.

RESEARCH AND DEVELOPMENT

Research and development expense increased 20% to $2,000,000 for fiscal 1995
from $1,669,000 for fiscal 1994.  The Surgical Business and the Imaging
Business accounted for 32% and 68%, respectively, of these expenditures for
fiscal 1995, as compared to 25% and 75%, respectively, of these expenditures
for fiscal 1994. The majority of the research and development expense for the
Imaging Business was attributable to advancing the core technology associated
with the development of VOXELGEO and VOXELVIEW.  Developing and manufacturing
software is expensive and the investment in product development often
involves a long pay-back cycle.  The Company's plans include continued
investment in software

                                      31
<PAGE>

development for medical applications for which significant revenue is not
anticipated in the near term.  The Company expects that expenditures for
research and development in the Surgical Business will grow substantially,
while those for the Imaging Business will grow modestly for the foreseeable
future.

OPERATING INCOME (LOSS)

Operating income was $2,439,000 for fiscal 1995, compared to an operating
loss of $1,431,000 for fiscal 1994.  The Surgical Business accounted for
$2,187,000 of the operating profit, principally due to the increased revenue
from sales of PERI-STRIPS.  The Imaging Business accounted for $252,000 to
operating income, which was entirely due to revenue from the VOXELGEO source
code license (which contributed $1,322,000 to operating income in fiscal
1995).  The operating loss incurred in fiscal 1994 includes one-time
acquisition costs of approximately $420,000 related to the Vital Images
transaction.

OTHER INCOME AND EXPENSE

The Company had net other income of $266,000 in fiscal 1995.  In fiscal 1994,
the Company had net other expense of $438,000 due to capital losses on an
investment in mutual fund shares of the Piper Jaffray Institutional
Government Income Portfolio in which the Company invested in 1994 (the
"Fund").  The Fund invested in various bonds and other obligations issued
or guaranteed as to payment of principal and interest by the United States
Government.  Included in the investments of the Fund were mortgage-related
securities and their derivatives, such as interest-only and principal-only
securities and inverse floating rate securities.  During the first quarter of
calendar 1994, the Fund's value declined.  The Company closely monitored its
investment in the Fund and held discussions with the Fund's management
concerning their recovery strategy. The Company decided to sell its shares in
the Fund when it believed that any meaningful recovery was no longer possible
in a reasonable time frame, and as concern about the Fund continued to
aggravate the immediate downside potential. The Company liquidated these
mutual fund shares late in fiscal 1994.

Affiliates of the Fund have entered into a settlement agreement with
plaintiffs in certain litigation relating to the Fund.  The settlement
agreement has received approval from the United States District Court where
the litigation is venued and from the affected Fund shareholders.  The
Company is entitled to participate in the settlement and its loss, for
purposes of determining payment under the settlement, has been fixed at
$315,000, but only a portion of this will actually be received by the
Company.  The amount and timing of any such settlement payment to the Company
is not yet determinable.

INCOME TAXES

As of October 31, 1995, the Company had used all of its remaining
unrestricted net operating loss ("NOL") carryforwards available to offset
income from operations.  The 1995 effective tax rate varies from the
statutory tax rate primarily due to the utilization of these carryforwards.
The Company has research and experimentation (R&E) tax credit carryforwards
available to offset income from operations, although the Company has not
finalized its estimation of such carryforwards.  It also has carryforwards of
$500,000 available to offset future capital gains and approximately $1.5
million of carryforwards arising from pre-merger losses of Vital Images
available to offset post-merger income of Vital Images during years in which
it is profitable.  A portion of the pre-merger loss carryforwards that may be
used in any year is restricted due to limitations resulting from the
significant change of ownership.  The deferred tax assets associated with the
carryforwards have been totally offset by a valuation allowance because of
uncertainty that sufficient taxable income of the appropriate type will be
generated prior to the expiration of the carryforwards. The tax provisions
for fiscal 1994 and 1993 represent alternative minimum taxes.

EFFECT OF ONE-TIME SOURCE CODE LICENSE

A one-time license fee for the VOXELGEO source code recorded in the fourth
quarter of fiscal 1995 contributed $1,500,000 to net revenue and $1,322,000
to operating income in both the quarter and the year.  After resulting income
taxes, the licensing transaction contributed 11 cents to fourth quarter net
income and 12 cents to the net income for the year.

COMPARISON OF THE YEAR ENDED OCTOBER 31, 1994 WITH THE YEAR ENDED OCTOBER 31,
1993

NET REVENUE

Net revenue increased 8% to $6,632,000 for fiscal 1994 from $6,144,000 for
fiscal 1993. The increase was due entirely to a 12% increase in revenue of
the Surgical Business when comparing these periods. Tissue-Guard net revenue
increased 88% to $1,675,000 for fiscal 1994 from $891,000 for fiscal 1993.
PERI-STRIPS accounted for 88% of the increase in Tissue-Guard product line
net revenue.

Biograft net revenue decreased 14% for fiscal 1994 when compared to fiscal
1993. The Company believes that this decline was strongly influenced by the
changing health care environment, specifically cost containment, which
prompted surgeons to choose drug therapy more frequently than surgical
intervention in the treatment of peripheral vascular disease. Net revenue of
the surgical productivity tools increased 3% between fiscal 1994 and fiscal
1993.

Net revenue of the Imaging Business decreased 2% between fiscal 1994 and
fiscal 1993. The Company believes that the decrease, which was primarily in
software license revenues, arose from the market's anticipation of VOXELGEO
2.0 and customers' decisions to delay software purchases until the delivery
of this version of the VOXELGEO software, offset by maintenance revenue
increases.

GROSS MARGIN

The gross margin percentage increased to 63% of net revenue for fiscal 1994
from 59% of net revenue for fiscal 1993. Gross margin percentages of the
Surgical Business were 61% and 58% in fiscal 1994 and fiscal 1993,
respectively. This improvement in the Surgical Business gross margin was
primarily due to the lower average cost of labor associated with the addition
of significant numbers of entry-level production personnel in response to
anticipated sales increases of PERI-STRIPS. Gross margin percentages of the
Imaging Business were 70% and 60% in fiscal 1994 and 1993, respectively. The
increase in the Imaging Business gross margin percentage was due to product
and service mix.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expense increased 13% to $3,541,000 for
fiscal 1994 from $3,126,000 for fiscal 1993 and increased slightly as a
percentage of sales to 53% for fiscal 1994 from 51% for fiscal 1993. The
increase in expense was primarily attributable to retention of a Chief
Operating Officer in April 1994 and the increased level of business activity
of the Surgical Business.

RESEARCH AND DEVELOPMENT

Research and development expense increased 74% to $1,669,000 for fiscal 1994
from $959,000 for fiscal 1993 and increased as a percentage of net revenue to
25% for fiscal 1994 from 16% in fiscal 1993. The majority of the increase was
attributable to advancing the core technology of the Imaging Business
concurrent with the development of VOXELGEO 2.0. In both fiscal 1994 and
fiscal 1993, 25% of research and development expenditures were for the
Surgical Business and 75% were for the Imaging Business.

ACQUISITION COSTS

The costs of the acquisition of Vital Images, which were all incurred in
fiscal 1994, were $420,000. These one-time costs, which accounted for 29% of
the operating loss incurred by the Company in fiscal 1994, were for legal,
accounting, and other professional fees.


                                      33
<PAGE>

OPERATING INCOME (LOSS)

The Company had operating losses of $1,431,000 and $457,000 in fiscal 1994
and fiscal 1993, respectively. The Surgical Business had operating income of
$171,000 and $333,000 and the Imaging Business had operating losses of
$1,183,000 and $790,000 for fiscal 1994 and fiscal 1993, respectively. The
increase in the Company's operating loss arose primarily from the increase in
research and development expenditures and the cost of the acquisition of
Vital Images.

OTHER INCOME AND EXPENSE

During fiscal 1994, the Company invested some of its excess cash in the Fund.
The Company sold its investment in the Fund during September and October of
1994 and realized a capital loss of $610,000 which resulted in net other
expense of $438,000 in that fiscal year.

LIQUIDITY AND CAPITAL RESOURCES

The Company's capital resources increased significantly during fiscal 1995 as
the result of the completion of a public offering of 1,800,000 shares of
Common Stock during September 1995, which provided approximately $26,000,000
to the Company, net of offering costs.  Primarily as a result of this
offering, the Company's cash, cash equivalents and marketable securities
balances increased by $26,678,000 from $3,619,000 at October 31, 1994 to
$30,297,000 at October 31, 1995.  Nine million dollars of the increase is
invested long-term (two years or less from date of investment) in obligations
of the U.S. government.  Working capital at October 31, 1995 was $23,916,000,
increasing $18,701,000 from $5,215,000 at October 31, 1994.

Historically, the cash needs of the Company have been met by cash generated
from operations and investments.  Cash flow from operating activities was
$1,922,000 during fiscal 1995.  Of the $1,922,000, approximately $950,000
after income tax can be attributed to the one-time license fee for VOXELGEO.
Primary cash usage resulted from increased levels of inventories and accounts
receivable associated with the growth in Surgical Business revenue, which
used $2,000,000 of cash, while increases in accounts payable and accrued
liabilities generated $1,281,000 in cash.  The Company used approximately
$800,000 in operating activities during 1994, largely due to surgical
business growth.  The Company made capital expenditures during fiscal 1995
totaling $1,353,000; $1,045,000 for the Surgical Business, which included
$235,000 for manufacturing equipment, $176,000 for computer hardware and
software, and $442,000 for leasehold improvements to its new facility; and,
$308,000 for the Imaging Business, primarily for computer hardware and
software. Additionally, the exercise of stock options provided $413,000.  On
December 1, 1995, the Company used $500,000 to acquire the PERI-GUARD patent.
The Company currently has no other commitments for material capital
expenditures in fiscal 1996, but continually reviews external growth
opportunities that may result in material commitments.

The Company believes its present level of cash and cash equivalents and
marketable securities will be sufficient to satisfy the Company's cash
requirements for the foreseeable future.

INFLATION

Management believes inflation has not had a material effect on the Company's
operations or on its financial condition.

FOREIGN CURRENCY TRANSACTIONS

Substantially all of the Company's foreign transactions are negotiated,
invoiced and paid 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.

REPORT OF INDEPENDENT ACCOUNTANTS




To the Board of Directors and Shareholders of
Bio-Vascular, Inc.:

     We have audited the accompanying consolidated balance sheets of
Bio-Vascular, Inc. as of October 31, 1995 and 1994 and the related
consolidated statements of operations, shareholders' equity and cash flows
for each of the three years in the period ended October 31, 1995.  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
Bio-Vascular, Inc. as of October 31, 1995 and 1994, and the consolidated
results of its operations and its cash flows for each of the three years in
the period ended October 31, 1995, in conformity with generally accepted
accounting principles.

(1)   BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BUSINESS DESCRIPTION:

As a result of the acquisition of Vital Images, Incorporated (Vital Images)
in fiscal 1994 (Note 2), Bio-Vascular, Inc. (the Company or Bio-Vascular) has
two businesses, a SURGICAL BUSINESS (the business which existed prior to the
acquisition of Vital Images) and an IMAGING BUSINESS (the business of Vital
Images prior to the merger). The Surgical Business develops, manufactures and
markets proprietary specialty medical products used in thoracic, cardiac,
neuro and vascular surgery.  The Surgical Business markets its products
through a worldwide network of distributors and independent sales
representatives. The Company, through its wholly owned subsidiary, Vital
Images, develops, markets and supports certain software products for
interactive visualization and analysis of three-dimensional Medical Image
data. The end users of the Imaging Business' software have been primarily
researchers and innovators who have adapted the core technology to meet their
needs.  The Company, as a result of the November 1995 510(k) clearance of
VOXELVIEW, will aggressively pursue clinical customers for its Medical
Imaging software.  The Company will also consider OEM arrangements.  During
fiscal 1994 and 1995, the primary focus of the Imaging Business was one of
development, directed toward specific industry applications of its core
technology. Also during fiscal 1994 and 1995, the Imaging Business has sought
to establish marketing and customer support alliances, enabling it to direct
increased resources toward the development process.

CONSOLIDATION:

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.

CASH EQUIVALENTS:

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 equivalents are concentrated in a commercial paper at
October 31, 1995.

MARKETABLE SECURITIES:

Investments having original maturities in excess of three months are
classified as marketable securities and generally  consist of  U.S.
Government or U.S. Government-backed obligations.  Investments are classified
as short-term or long-term in the balance sheet based on their maturity date.

At October 31, 1995 all of the Company's marketable securities are classified
as available-for-sale and all mature in two years or less.  At October 31,
1995, the estimated fair value of the securities approximated their cost.
Unrealized gains and losses were not significant.  The Company's marketable
securities at October 31, 1994 were classified as held-to-maturity and
matured during 1995.

INVENTORIES:

Inventories are valued at the lower of cost or market, utilizing standard
costs which approximate the first-in, first-out method. All inventories are
held by the Surgical Business.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS:

Equipment and leasehold improvements are stated at cost. Depreciation and
amortization are computed using accelerated and straight-line methods over
the estimated useful lives (three to seven years) or lease life. Major
replacements and improvements are capitalized, and maintenance and repairs
which do not improve or extend the useful lives of the respective assets are
charged to operations. The asset and related accumulated depreciation or
amortization accounts are adjusted for asset retirement or disposal with the
resulting gain or loss shown in non-operating income.

- --------------------------------------------------------------------------------

SOFTWARE DEVELOPMENT COSTS:

Software development costs incurred in the research and development of new
software products are expensed as incurred until technological and market
feasibility have been established.  After technological and market
feasibility is established, any additional development or enhancement costs
for these products are capitalized until the product is available for sale to
customers. Amortization of capitalized costs is computed using the
straight-line method based upon a one to three year estimated economic life
of the software products. If delays in product releases lead to uncertainty
concerning the ultimate recovery of capitalized costs, those costs are
expensed at the time recovery becomes uncertain.

GOODWILL, PRODUCT LICENSES AND OTHER INTANGIBLES:

Goodwill, product licenses and other intangibles of the Surgical Business are
recorded at cost and are being amortized using the straight-line method over
ten years. In 1992, the Imaging Business acquired a license (Note 6) which
was being amortized on a straight-line basis over the estimated period of
realizability of three years and is fully amortized as of October 31, 1995.
The Company evaluates the net realizability of goodwill and other intangibles
on an ongoing basis based on current and anticipated undiscounted cash flows.

REVENUE RECOGNITION:

The Company recognizes Surgical Business revenue and software revenues of the
Imaging Business upon shipment of the products. Included in the sales price
of the Imaging Business' software products is an initial maintenance contract
varying in length from three to six months. Renewal maintenance contracts are
generally one year in length. Revenue from maintenance contracts, including
those sold as part of its software products and those sold separately, is
deferred and recognized on a straight-line basis over applicable maintenance
contract periods. Costs associated with maintenance revenues are charged to
operations as incurred.

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"). Temporary differences relate primarily to the
allowance for doubtful accounts, obsolete inventory reserves, vacation
accruals and depreciation.

USE OF ESTIMATES:

The preparation of the Company's consolidated financial statements in
conformity with generally accepting accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods.   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 allowance for
obsolete inventory and uncollectable accounts receivable, the evaluation of
realizability of intangible and deferred tax assets, and capitalization of
software development costs.

NET INCOME (LOSS) PER COMMON SHARE:

Net income (loss) per common share is computed by dividing net income (loss)
by the weighted average number of common and common equivalent shares
outstanding. Common equivalent shares relate to common stock options and
warrants, when their effect is not antidilutive.

(2)   ACQUISITION:

On May 24, 1994, Bio-Vascular acquired Vital Images. The acquisition was
effected through a "stock for stock" exchange of 1,645,025 shares of
Bio-Vascular common stock for the 1,645,025 shares of Vital Images common and
Series A preferred stock outstanding. The merger was accounted for under the
"pooling-of-interests" method of accounting for financial reporting purposes.
Accordingly, the accompanying consolidated financial statements have been
restated to retroactively include the financial position, results of
operations and cash flows of Vital Images for all periods presented.

Combined and separate results of Bio-Vascular and Vital Images for periods
prior to the acquisition are set forth in the table below. Costs related to
the acquisition of approximately $420,000 were expensed as incurred in the
first through third quarters of fiscal year 1994.

(1) Relates entirely to the Company's investment during 1993 and 1994 in
    mutual fund shares of the Piper Jaffray Institutional Government Income
    Portfolio.  The Company liquidated its investment in the fund as of
    October 31, 1994.

(4) INCOME TAXES:

The recorded tax provisions for the years ended October 31, 1993 and 1994
represent alternative minimum taxes due to limitations in the use of net
operating loss carryforwards and state minimum taxes. The Company has
recorded a tax provision for October 31, 1995 of $519,000 after utilization
of $1,518,000 net operating loss carryforwards.  The 1995 effective tax rate
varies from the statutory tax rate primarily due to the utilization of these
carryforwards.  The Surgical Business of the Company utilized approximately
$740,000 of net operating loss carryforwards in fiscal 1993.  The Company
incurred a loss for the year ended October 31, 1994.

As of October 31, 1995, the Company has a capital loss carryforward of
$500,000 available to offset future capital gain income, and research and
experimentation tax credit carryforwards. The capital loss carryforward
expires in 1999.  The Company also has carryforwards arising from the
pre-merger losses of Vital Images totaling approximately $1,500,000. These
pre-merger carryforwards can only be applied to the post-merger net income of
the Imaging Business and are restricted as to the amount that can be utilized
in any year due to limitations resulting from a significant change of
ownership. These carryforwards begin to expire in 2005.

The deferred tax assets associated with the pre-merger loss carryforwards and
the capital loss carryforward have been totally offset by a valuation
allowance because of uncertainty that the Company and the Imaging Business
will generate sufficient taxable income of the appropriate type prior to the
expiration of the carryforwards.  The Company has not finalized its
estimation of research and experimentation (R&E) credit carryforwards and,
accordingly the deferred tax asset estimated to date associated with R&E
credits continues to be offset by a valuation allowance.

(5) SHAREHOLDERS' EQUITY:

    INCREASE IN AUTHORIZED SHARES:

In March 1995, the shareholders approved an increase in authorized shares of
common stock from 10,000,000 shares to 20,000,000 shares.

    WARRANTS:

During 1995, in connection with a stock offering and issuance of common
shares, the Company  issued to the underwriter warrants to purchase 90,000
shares of common stock, at an exercise price of $16.375 per share, commencing
on September 21, 1996.  These warrants will continue to be exercisable for a
period of four years.

As a result of the merger, the Company assumed the warrant obligations of
Vital Images which were outstanding at the time of the merger. During 1991,
in connection with the private placement and issuance of common shares, Vital
Images issued stock warrants for the purchase of 32,143 shares of common
stock. A total of 3,214 warrants were repurchased by the Company concurrent
with the 1995 stock offering.  The remaining 28,929 warrants are exercisable
through October 1996, at an exercise price of $4.00 per share.

    RESTRICTED STOCK:

Under certain compensation agreements, an arrangement which provides for
awards of restricted common stock to key management was adopted in 1992.
These awards of restricted common stock are subject to forfeiture if
employment terminates prior to the end of the prescribed periods. Vesting
periods range from two to four years. The market value of the shares at the
time of grant is recorded as unearned restricted stock. The unearned amount
is amortized to compensation expense over the periods during which the
restrictions lapse. During the years ended October 31, 1995, 1994, and 1993,
29,567, 14,302 and 13,744 restricted shares, respectively, were earned. At
October 31, 1995, 86,528 shares of restricted stock, which were granted at
per share prices of $3.25 to $14.50 and generally vest over a period of four
years, remain unearned.  As part of these same compensation agreements, the
Company agreed to buy back the number of shares which would allow the
employees to meet their income tax obligations arising from the non-cash
compensation related to the earned restricted shares.

    DEFERRED COMPENSATION:

Prior to the merger, Vital Images granted stock options at prices different
from the estimated market value of the underlying common stock. The
difference between the estimated market value and the exercise price was
recorded as deferred compensation and was amortized on a straight-line basis
over the vesting periods of the related options.  There is no remaining
deferred compensation as of October 31, 1995.

    STOCK OPTION PLANS:

The Company has four stock option plans, an Employee Incentive Stock Option
Plan (the "1988 Plan"), a Directors' Stock Option ("DSO") Plan, and two
plans, the obligations of which were assumed by the Company as a result of
the acquisition of Vital Images: the 1990 Management Incentive Stock Option
Plan (the "1990 Plan"), and the 1992 Stock Option Plan (the "1992 Plan").
The Company does not intend to grant further options under either the 1990 or
the 1992 plans.

Under the Company's plans, 478,332 shares of common stock remain reserved for
issuance to directors, officers and employees at October 31, 1995. Options
under the plans are exercisable over periods of up to ten years from the date
of grant. The Company has reserved and granted 261,720 shares of common stock
for issuance in connection with non-plan options which have been granted to
consultants, an officer, and directors of the Company. These options are
exercisable over periods of up to seven years from the date of grant. Option
activity is summarized as follows:

Options for the purchase of 589,803 shares of common stock at prices ranging
from $1.00 to $14.50 were exercisable at October 31, 1995.

Subsequent to the end of the 1995 fiscal year, the Company granted non-plan
options for the purchase of 200,000 shares of common stock to an officer of
the Company as part of his employment package.  These options vest equally
over five years.  The difference between the market price at the date of
grant and the exercise price will be amortized to operations over the vesting
period.   In addition, the Board of Directors approved and adopted the 1995
Stock Incentive Plan, subject to shareholder approval of the Plan, under
which 410,000 shares of the Company's common stock were reserved for
issuance.  Upon shareholder approval of the Plan, all of the Company's
existing Stock Option Plans, with the exception of the Director's Stock
Option Plan, will be terminated and no additional options are to be granted
thereunder, with any remaining shares reserved for issuance under these
previous plans now being reserved for issuance under the 1995 Plan.  The
Board of Directors also approved and adopted the Employee Stock Purchase
Plan, subject to shareholder approval of the Plan, under which 300,000 shares
of common stock were reserved for issuance, and also approved the
establishment of a wholly-owned foreign sales corporation subsidiary.

(6) COMMITMENTS AND CONTINGENCY

    OPERATING LEASES:

In February 1995, the Company entered into a new noncancelable operating
lease for rental of a combined office and production facility housing their
Surgical Business in St. Paul, Minnesota beginning August 1, 1995 and
expiring July 31, 2005. Total annual base rental expense for this new lease
is $255,441.   The Company also pays apportioned real estate taxes and common
costs on its leased facilities.   Vital Images leases office facilities for
the Imaging Business in Fairfield, Iowa, under a non-cancelable operating
lease expiring on June 1, 1997. The lease includes an option to renew for one
four-year period.  Total rent expense was $219,290, $167,260 and $148,964 for
the years ended October 31, 1995, 1994 and 1993, respectively.

Future minimum payments under all operating leases at both facility

    ROYALTIES:

In connection with the acquisition of product licenses and product
manufacturing rights, the Company is obligated for the payment of royalties
as follows:

    SURGICAL BUSINESS ROYALTIES:

- -   5% on net sales of PERI-STRIPS through December 2001, or if a patent is
    issued, until the expiration of the patent

- -   2.5% or 3% of net sales of the BIOGRAFT through 1998 (2.5% if BIOGRAFT
    annual sales are under $2,000,000; 3.0% if annual sales are over
    $2,000,000). In addition, a royalty of an additional 5% of net sales
    was in place through November 2, 1993 (which coincided with the
    expiration of the patent)

- -   5.5% of net sales of the FLO-RESTER occluder under two agreements with 3%
    payable through July 1995 and 2.5% payable through September 1996

- -   3% of net sales of PERI-GUARD Processed Bovine Pericardium and CARDIO-COOL
    through July of 1995

- -   3% of net sales of the BIO-VASCULAR PROBE through 2001

- -   5% on the next $1,369,555 of aggregate net sales of the Bioflow-Registered
    Trademark- Small Diameter Graft after October 31, 1994, and 7% on all net
    sales thereafter, payable through October 1998. The Company no longer
    actively markets this product.

Royalty expense for the Surgical Business was approximately $393,000,
$169,000, and $247,000 for the years ended October 31, 1995, 1994, and 1993,
respectively, and is included in cost of revenue.

    IMAGING BUSINESS ROYALTIES:

- -   5% of net sales of licensed volume visualization software (which
    encompasses the core technology) and direct descendant software. The
    royalty will terminate on May 24, 1996, two years after the merger of
    Vital Images with and into the Company.  Royalty fee expense under
    this arrangement totaled $152,857 for the year ended October 31, 1995,
    $58,875 for the year ended October 31, 1994 and $56,278 for the year ended
    October 31, 1993 and is included in cost of revenue.

    CONTINGENCY:

In May 1995, the Company terminated a distribution arrangement with a
Japanese distributor.  The distributor has claimed that the termination was
without cause and caused economic damage.  The distributor has threatened to
commence legal action, although, to date, has not done so.  The Company
believes the distributor's claim is without merit and intends to defend
itself vigorously should a legal claim be filed.

(7)  EMPLOYEE BENEFIT PLANS:

The Company has a salary reduction plan established on January 1, 1991, which
qualifies under Section 401(k) of the Internal Revenue Code. Employee
contributions are limited to 20% of their annual compensation, subject to
yearly limitations. At the discretion of the Board of Directors, the Company
may make matching contributions equal to a percentage of the salary reduction
or other discretionary amount. The Company has made no contributions to the
plan since its inception.

distributors accounting for in excess of 10% of the Company's gross revenue
for the period. For 1994 and 1993 there were no greater than 10%

customers. In addition, three domestic distributors account for an aggregate
of 47% of the Company's accounts receivable balance at October 31, 1995.

(9) SUBSEQUENT EVENTS:

    PATENT PURCHASE:

On December 1, 1995, the Company purchased the patent for PERI-GUARD.
PERI-GUARD is one of the Company's TISSUE-GUARD line of products. The
purchase gives the Company all rights, title, and interest to the PERI-GUARD
process. Prior to December 1, 1995, the Company's field of use was limited to
cardiovascular applications. In connection with this transaction, the Company
granted a non-exclusive license with respect to the development and sale of
products for urological and related applications utilizing the PERI-GUARD
process and the SUPPLE PERI-GUARD process.

    UNCERTAINTY:

Recent developments concerning reimbursement of LVR surgery are likely to
have a material adverse effect on the Company's business and results of
operations. Generally, Medicare had been reimbursing hospitals and surgeons
for LVR surgery since the procedure was re-introduced in 1994. LVR surgery
uses PERI-STRIPS, the product which has been primarily responsible for the
Company's growth in net revenue and net income in recent periods (see
"Surgical Business--Markets and Medical Need, Lung Volume Reduction Surgery"
on page 3 of this report). Recently, HCFA decided that it did not have enough
patient follow-up data to substantiate the safety and efficacy of LVR
surgery. On that basis, HCFA decided to cease reimbursement of LVR surgery
until its technical assessment committee ("TAC") could complete an evaluation
of the safety and efficacy of the procedure. TAC has set February 13, 1996 as
the final date for surgeons to submit patient data. It is reasonably expected
that once the data is received by TAC any decision regarding reimbursement
will take, at a minimum, two months and possibly a year or more. HCFA's
decision to deny reimbursement for LVR surgery is expected to have a material
adverse effect on the Company's net revenue and net income at a minimum in
the first and second quarters of fiscal 1996, and may continue to have such
an effect in future periods. While the Company believes, based on reported
outcomes, that HCFA will eventually approve reimbursement for LVR surgery,
the Company cannot say with any certainty when, or if, the reimbursement of
LVR will be approved. The Company believes that LVR procedures reimbursed by
Medicare constitute over 50% of total LVR procedures. While the Company
understands that private insurance companies and managed care organizations
(which the Company believes have been the third-party payors responsible for
a significant percentage of reimbursed LVR procedures) are currently
reimbursing LVR surgery based on their own evaluation of the procedure and
its outcomes, it is unknown whether these private payors will change their
reimbursement practices in light of HCFA's decision.

     In addition to the above, Landlord and Tenant mutually covenant and
agree as follows:

TENANT'S MAINTENANCE AND REPAIR OF PREMISES  Except as hereinafter provided,
Tenant shall maintain and keep the interior of the premises in good repair,

including alterations as may be necessary to fit the same for its business,
only upon first obtaining the written approval of Landlord as to the

Landlord shall forthwith proceed to repair such damage. During the period of
repair, Tenant's rent shall abate in whole or in part depending upon the use
of said premises for the normal purposes of Tenant's business. In the event
that Landlord shall fail to promptly commence repair of such damage, or
having commenced the same shall fail to prosecute such repair to completion
with due diligence after notice from Tenant, Tenant may at Tenant's
option upon fifteen (15) days written notice to Landlord, make or complete

payable under this lease.

covenant to pay rent, and such failure shall continue unremedied or
uncorrected for a period of fifteen (15) days after the service of written
notice upon such party by the other party hereto, specifying such failure,
this lease may be terminated, at the option of the party serving such notice,
at the expiration of such period of fifteen (15) days; provided, however,
that such termination shall not relieve the party so failing from liability
to the other party for such damages as may be suffered by reason of such
failure.

CONDEMNATION  In the event that the leased premises shall be taken for public
use by the city, state, federal government, public authority or other
corporation having the power of eminent domain, then this lease shall
terminate as of the date on which possession thereof shall be taken for such
public use, or, at the option of the Tenant, as of the date on which the
premises shall become unsuitable for Tenant's regular business by reason of
such taking. If only a part of the lease premises shall be taken and Tenant
shall remain a tenant of the building, the rent shall be abated
proportionately.

ASSIGNMENT  Tenant may not assign this lease or sublet the premises or any
part thereof without the written consent of Landlord which shall not be
unreasonably withheld. If any assignment or sublease is made by Tenant with
Landlord's consent, Tenant shall remain liable as surety under the terms
hereof notwithstanding such assignment or sublease. Landlord has granted

assessed and levied upon the leased premises or any part thereof during the
said term as they become due.

disputes hereunder shall be settled by arbitration in Fairfield, Iowa in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association, and judgment thereon may be entered in any court of competent
jurisdiction.

LANDLORD'S RIGHT TO ENTER PREMISES  Tenant shall permit Landlord and
Landlord's agents to enter at all reasonable times to view the state and
condition of the premises or to make such alterations or repairs therein as
may be necessary for the safety and preservation thereof, or for any other
reasonable purposes. Tenant shall also permit Landlord or Landlord's agents,
on or after sixty (60) days next preceding the expiration of the term of this
lease, to show the premises to prospective tenants at reasonable times, and
to place notices on the front of said premises, or on any part thereof,
offering the premises for lease or for sale.

TERMINATION OF LEASE  Signing of this lease terminates any previous lease
between Landlord and Tenant as of June 1, 1993.

Tenant shall peaceably hold and enjoy the determined premises for the term of
this lease free from molestation, eviction, or disturbance by the Landlord.

AND IT IS MUTUALLY UNDERSTOOD AND AGREED that the covenants and agreement

Improvement Allowance").  The Tenant Improvement Allowance shall be
disbursed by Landlord to Tenant in two installments, the first upon fifty
percent (50%) completion of the Tenant Improvements and the second on full
completion of the Tenant Improvements.  Disbursements shall be made subject

In connection with the Tenant Improvements to be constructed and installed by
Tenant, it is specifically agreed, as follows:

      the Tenant Improvements, who in turn shall agree to utilize only union
      subcontractors on the project.

   B. Tenant shall be responsible for compliance of all work with the approved
      plans and all applicable codes, laws, regulations and the like.

1.4 LEASE TERM.  The term of this Lease shall commence on one hundred five
(105) days after delivery of Premises to Tenant pursuant to Section 1.5
hereof ("Commencement Date") and shall terminate one hundred twenty (120)

period and all of the terms and provisions of this Lease shall be applicable
during that period, except that Tenant shall pay Landlord as base rental for
the period of such holdover an amount equal to one and one-half (1) times the
base rent which would have been payable by Tenant had the holdover period

day for each day after the Delivery Date that the Premises are delivered.

parties shall have no further obligations hereunder, except that Landlord
shall remain liable for payment of liquidated damages, as set forth above, to
the date of termination.  To be effective, Tenant must exercise its right of
termination within five (5) days of the date established for Landlord's
performance (i.e., July 1, 1995).

Following completion of Tenant's work, Tenant shall be entitled to occupy the
Premises and conduct its business therein. Additionally, Landlord agrees to

Lease, except for Tenant's obligation of payment of rent and operating
expenses, which obligation shall commence on the Commencement Date of the

             ARTICLE 2. RENT, OPERATING EXPENSES AND SECURITY DEPOSIT

2.1 BASE RENT.  Tenant agrees to pay monthly as base rent during the term of
this Lease the sum of money set forth in Section 1.6 of this Lease, which
amount shall be payable to Landlord at the address shown above.  One monthly
installment shall be due and payable on or before the first day of each
calendar month succeeding the Commencement Date during the term of this
Lease; provided, if the Commencement Date should be a date other than the
first day of a calendar month, the monthly rental set forth above shall be
prorated to the end of that calendar month, and all succeeding installments
of rent shall be payable on or before the first day of each succeeding
calendar month during the term of this Lease.  Tenant shall pay, as
additional rent, all other sums due under this Lease.

2.2 OPERATING EXPENSES.Tenant shall also pay as additional rent Tenant's pro
rata share of the operating expenses of Landlord for the Building.  Landlord
may invoice Tenant monthly for Tenant's pro rata share of the estimated
operating expenses for each calendar year, which amount shall be adjusted
from time-to-time by Landlord based upon anticipated operating expenses.
Within six (6) months following the close of each calendar year, Landlord
shall provide Tenant an accounting showing in reasonable detail the
computations of additional rent due under this Section.  In the event the
accounting shows that the total of the monthly payments made by Tenant
exceeds the amount of additional rent due by Tenant under this Section, the
accounting shall be accompanied by evidence of a credit to Tenant's account.
In any event the accounting shows that the total of the monthly payments made
by Tenant is less than the amount of additional rent due by Tenant under this
Section, the accounting shall be accompanied by an invoice for the additional
rent.  Notwithstanding any other provisions in this Lease, during the year in
which this Lease terminates, Landlord, prior to the termination date, shall
have the option to invoice Tenant for Tenant's pro rata share of the
operating expenses based upon the previous year's operating expenses.  If
this Lease shall terminate on a day other than the last day of a calendar
year, the amount of any additional rent payable by Tenant applicable to the
year in which the termination shall occur shall be prorated on the ratio that
the number of days from the commencement of the calendar year to and
including such termination date bears to 365.  Tenant agrees to pay any
additional rent due under this Section within ten (10) days following receipt
of the invoice or accounting showing additional rent due.  Tenant's pro rata
share set forth in Section 1.9 shall be equal to a percentage based upon a
fraction, the numerator of which is the net rentable area of the Premises as
set forth in Article 1 and the denominator of which shall be the net rentable
area of the Building, as the same may change from time to time.

2.3 DEFINITION OF OPERATING EXPENSES.The term "operating expenses" includes
all expenses incurred by Landlord with respect to the maintenance and
operation of the Building, including, but not limited to, the following:
maintenance, repair and replacement costs; electricity, fuel, water, sewer,
gas and other common Building utility charges for the common areas;


                                      -1-
<PAGE>

equipment used for maintenance and operation of the Building; operational
expenses; exterior window washing and janitorial services (for common areas);
trash and snow removal; landscaping and pest control; reasonable management
fees, wages and benefits payable to employees of Landlord whose duties are
directly connected with the operation and maintenance of the Building; all
services, supplies, repairs, replacements or other expenses for maintaining
and operating the Building and appurtenant improvements, including parking
and common areas; improvements made to the Building which are required under
any governmental law or regulation that was not applicable to the Building at
the time it was constructed; installation of any device or other equipment
which improves the operating efficiency of any system within the Premises and
thereby reduces operating expenses; all other expenses which would generally
be regarded as operating, repair, replacement and maintenance expenses; all
real property taxes and installments of special assessments (excluding
special assessments levied prior to the Commencement Date) and legal fees
incurred in connection with actions to reduce the same; and all insurance
premiums Landlord is required to pay or reasonably deems necessary to pay,
including fire and extended coverage, and rent loss and public liability
insurance, with respect to the Building.

The following items shall not constitute nor be included in operating
expenses:  debt service, leasing commissions, executive salaries and
overhead, non-cash charges or reserves, costs to correct defects in design or
original construction, or costs which are reimbursed by others (except tenant
payments of pro rata shares of operating expenses).  For the years 1995, 1996
and 1997, the Tenant's pro rata share of operating expenses shall be capped
at One and no/100 Dollars ($1.00) per square foot per year, and One and
20/100 Dollars ($1.20) per square foot per year, and Three and 75/100 Dollars
($3.75) per square foot per year, respectively.

2.4 INCREASE IN INSURANCE PREMIUMS.  If an increase in any insurance premiums
paid by Landlord for the Building is caused by Tenant's particular use of the
Premises or if Tenant vacates the Premises and causes an increase in such
premiums, then Tenant shall pay as additional rent the amount of such
increase to Landlord.

Tenant shall occupy the Premises, conduct its business and control its
agents, employees, invitees and visitors in such a manner as is lawful,
reputable and will not create a nuisance.  Tenant shall not permit any
operation which emits any odor or matter which intrudes into other portions
of the Building or otherwise interfere with, annoy or disturb any other
lessee in its normal business operations or Landlord in its management of the
Building.  Tenant shall not permit any waste on the Premises to be used in
any way which would, in the opinion of Landlord, be extra hazardous on
account of fire or which would, in any way, increase or render void the fire
insurance on the Building.

Tenant shall be responsible for proper disposal of all biological or medical
waste and all other material utilized in the conduct of Tenant's business,
strictly in accordance with all applicable local, state and federal laws and
regulations.

which signs are in conformance with Landlord's sign criteria, if any,
established for the Building.

3.3 COMPLIANCE WITH LAWS, RULES AND REGULATIONS.  Tenant, at Tenant's sole
cost and expense, shall comply with all laws, ordinances, orders, rules and
regulations of state, federal, municipal or other agencies or bodies having
jurisdiction over the use, condition or occupancy of the Premises.  Tenant
will comply with the reasonable, nondiscriminatory rules and regulations of
the Building adopted by Landlord.  Landlord shall have the right at all times
to change and amend the rules and regulations in any reasonable manner as may
be deemed advisable for the safety, care, cleanliness, preservation of good
order and operation or use of the Building or the Premises.  All rules and
regulations of the Building will be sent by Landlord to Tenant in writing and
shall thereafter be carried out and observed by Tenant.

Landlord warrants that on the Commencement Date the Building and Landlord's
work within the Premises will be in compliance with all applicable laws,
regulations and ordinances, and that the use of the Premises, as described in
Section 1.7 is permitted under applicable ordinances.

3.4 WARRANTY OF POSSESSION.  Landlord warrants that it has the right and
authority to execute this Lease, and Tenant, upon payment of the required
rents and subject to the terms, conditions, covenants and agreements
contained in this Lease, shall have possession of the Premises during the
full term of this Lease as well as any extension or renewal thereof.
Landlord shall not be responsible for the acts or omissions of any other
lessee or third party beyond its control that may interfere with Tenant's use
and enjoyment of the Premises.

3.5 RIGHT OF ACCESS.  Landlord or its authorized agents shall, at any and all
reasonable times, upon reasonable notice and with reasonable precautions,
have the right to enter the Premises to inspect the same, to show the
Premises to prospective purchasers, lessees (during the last six (6) months
of the lease term), mortgagees, insurers or other interested parties, and to
alter, improve or repair the Premises or any other portion of the Building.
Tenant hereby waives any claim for damages for injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or use of the
Premises, and any other loss occasioned thereby.  Tenant shall not change
Landlord's lock system or in any other manner prohibit Landlord from entering
the Premises.  Landlord shall have the right to use any and all reasonable
means which Landlord may deem proper to open any door in an emergency without
liability therefor.  Tenant shall permit Landlord to erect, use, maintain and
repair pipes, cables, conduits, plumbing, vents and wires in, to and through
the Premises as often and to the extent that Landlord may now or hereafter
deem to be necessary or appropriate for the proper use, operation and
maintenance of the Building.  Landlord will exercise its best efforts to
minimize disruption to Tenant's business in connection with the foregoing.

                   ARTICLE 4. UTILITIES AND ACTS OF OTHERS

4.1 BUILDING SERVICES.  Tenant shall pay when due, all charges for utilities
furnished to or for the use or benefit of Tenant or the Premises.  Tenant
shall have no claim for rebate of rent on account of any interruption in
service, but Landlord shall exercise its best efforts to promptly restore
interrupted services.

Tenant's property or personal injury caused by criminal acts or entry by
unauthorized persons into the Premises or the Building, except where caused

                       ARTICLE 5. REPAIRS AND MAINTENANCE

5.1. LANDLORD REPAIRS.  Landlord shall not be required to make any
improvements, replacements or repairs of any kind or character to the
Premises or the Building during the term of this Lease except as are set
forth in this Section.  Landlord shall maintain only the roof, foundation,
parking and common areas, the structural soundness of the exterior walls,
doors, corridors, and other structures serving the Premises, provided, that
Landlord's cost of maintaining, replacing and repairing the items set forth
in this Section are operating expenses subject to the additional rent
provisions in Section 2.2 and 2.3.  Landlord shall not be liable to Tenant,
except as expressly provided in this Lease, for any damage or inconvenience,
and Tenant shall not be entitled to any abatement or reduction of rent by
reason of any repairs, alterations or additions made by Landlord under this
Lease.

5.2 TENANT REPAIRS.  Tenant shall, at all times throughout the term of this
Lease, including renewals and extensions, and at its sole expense, keep and
maintain the Premises in a clean, safe, sanitary and first class condition
and in compliance with all applicable laws, codes, ordinances, rules and
regulations.  Tenant's obligations hereunder shall include, but not be
limited to, the maintenance, repair and replacement, if necessary, of all
heating, ventilation, air conditioning, lighting and plumbing fixtures and
equipment, fixtures, motors and machinery, all interior walls, partitions,
doors and windows, including the regular painting thereof, all exterior
entrances, windows, doors and docks and the replacement of all broken glass.
When used in this provision, the term "repairs" shall include replacements
or renewals when necessary, and all such repairs made by the Tenant shall be
equal in quality and class to the original work.  The Tenant shall keep and
maintain all portions of the Premises and the sidewalk and areas adjoining
the same in a clean and orderly condition, free of accumulation of dirt,
rubbish, snow and ice. If Tenant fails, refuses or neglects to maintain or
repair the Premises as required in this Lease after notice shall have been
given Tenant, in accordance with this Lease, Landlord may make such repairs
without liability to Tenant for any loss or damage that may accrue to
Tenant's merchandise, fixtures or other property or to Tenant's business by
reason thereof, and upon completion thereof, Tenant shall pay to Landlord all
costs plus fifteen percent (15%) for overhead incurred by Landlord in making
such repairs upon presentation to Tenant of bill therefor.

5.3. TENANT DAMAGES.  Tenant shall not allow any damage to be committed on
any portion of the Premises or Building or common areas, and at the
termination of this lease, by lapse of time or otherwise, Tenant shall
deliver the Premises to Landlord in as good condition as existed at the
Commencement Date of this Lease, ordinary wear and tear excepted.  The cost
and expense of repairs necessary to restore the condition of the Premises
shall be borne by Tenant.

                   ARTICLE 6. ALTERATIONS AND IMPROVEMENTS

6.1 TENANT IMPROVEMENTS.  Tenant shall not make or allow to be made any
alterations or physical additions in or to the Premises without first
obtaining the written consent of Landlord, which consent shall not be
unreasonably withheld.  Any alterations, physical additions or improvements
to the Premises made by Tenant shall at once become the property of Landlord
and shall be surrendered to Landlord upon the termination of this Lease;
provided, however, Landlord may, at the time of and as a condition to
granting consent, require Tenant to remove any physical additions and/or
repair any alterations in order to restore the Premises to the conditions
existing at the time Tenant took possession, all costs of removal and/or
alterations to be borne by Tenant.  This clause shall not apply to moveable
equipment or furniture owned by Tenant, which may be removed by Tenant at the
end of the term of this Lease if Tenant is not then in default and if such
equipment and furniture are not subject to any other rights, liens and
interests of Landlord.

                     ARTICLE 7. CASUALTY AND INSURANCE

7.1 SUBSTANTIAL DESTRUCTION.  If all or a substantial portion of the Premises
or the Building should be totally destroyed by fire or other casualty and the
Building is not being restored, or if the Premises or the Building should be
damaged so that rebuilding cannot reasonably be completed within one hundred
eighty (180) working days after the date of written notification by Tenant to
Landlord of the destruction, or if insurance proceeds are not made available
to Landlord, or are inadequate, for restoration, this Lease shall terminate
at the option of Landlord by written notice to Tenant within sixty (60) days
following the occurrence, and the rent shall be abated for the unexpired
portion of the Lease effective as of the date of the written notification.

7.2 PARTIAL DESTRUCTION.  If the Premises should be partially damaged by fire
or other casualty, and rebuilding or repairs can reasonably be completed
within one hundred eighty (180) working days from the date of written
notification by Tenant to Landlord of the destruction, and insurance proceeds
are adequate and available to Landlord for restoration, this Lease shall not
terminate, and Landlord shall at its sole risk and expense proceed with
reasonable diligence to rebuild or repair the Building or other improvements
to substantially the same condition in which they existed prior to the
damage.  If the Premises are to be rebuilt or repaired and are untenantable
in whole or in part following the damage, the rent payable under this Lease
during the period for which the Premises are untenantable shall be adjusted
to such an extent as may be fair and reasonable under the circumstances.  In
the event that Landlord fails to complete the necessary repairs or rebuilding
within one hundred eighty (180) working days from the date of written
notification by Tenant to Landlord of the destruction, Tenant may at its
option terminate this Lease by delivering written notice of termination to
Landlord, whereupon all rights and obligations under this Lease shall cease
to exist.

7.3 PROPERTY INSURANCE.  Landlord shall not be obligated in any way or manner
to insure any personal property (including, but not limited to, any
furniture, machinery, goods or supplies) of Tenant upon or within the
Premises, any fixtures installed or paid for by Tenant upon or within the
Premises, or any improvements which Tenant may construct on the Premises
(except the initial Tenant Improvements).  Tenant shall maintain property
insurance on its personal property and shall also maintain plate glass
insurance.  Tenant shall have no right in or claim to the proceeds of any
policy of insurance maintained by Landlord even if the cost of such insurance
is borne by Tenant as set forth in Article 2.

7.4 WAIVER OF SUBROGATION.  Anything in this Lease to the contrary
notwithstanding, Landlord and Tenant hereby waive and release each other of
and from, to the extent normally insurable, any and all right of recovery,
claim, action or cause of action, against each other, their agents, officers
and employees, for any loss or damage that may occur to the Premises, the
Building or personal property within the Building, by reason of fire or the
elements, regardless of cause or origin, including negligence of Landlord or
Tenant and their agents, officers and employees.  Landlord and Tenant agree
immediately to give their respective insurance companies which have issued
policies of insurance covering all risk of direct physical loss, written
notice of the terms of the mutual waivers contained in this Section.

7.5 HOLD HARMLESS.  Landlord shall not be liable to Tenant's employees,
agents, invitees, licensees or visitors, or to any other person, for an
injury to person or damage to property on or about the Premises caused by any
act or omission of Tenant, its agents, servants or employees, or of any other
person entering upon the Premises under express or implied invitation by
Tenant, or caused by the improvements located on the Premises becoming out of
repair, the failure or cessation of any service provided by Landlord
(including security service and devices), or caused by leakage of gas, oil,
water or steam or by electricity emanating from the Premises, unless caused
by the sole negligence or willful misconduct of Landlord.  Tenant agrees to
indemnify and hold harmless Landlord of and from any loss, attorney's fees,
expenses or claims arising out of any such damage or injury.

7.6 PUBLIC LIABILITY INSURANCE.  Tenant shall during the term hereof keep in
full force and effect at its expense a policy or policies of public liability
insurance with respect to the Premises and the business of Tenant, on terms
and with companies approved in writing by Landlord, in which both Tenant and
Landlord shall be covered by being named as insured parties under reasonable
limits of liability not less than $1,000,000, or such greater coverage as
Landlord may reasonably require, combined single limit coverage for injury or
death.  Such policy or policies shall provide that thirty (30) days' written
notice must be given to Landlord prior to cancellation thereof.  Tenant shall
furnish evidence satisfactory to Landlord at the time this Lease is executed
that such coverage is in full force and effect.

                            ARTICLE 8. CONDEMNATION

8.1 SUBSTANTIAL TAKING.  If all or a substantial part of the Premises are
taken for any public or quasi-public use under any governmental law,
ordinance or regulation, or by right of eminent domain or by purchase in lieu
thereof, and the taking would prevent or materially interfere with the use of
the Premises for the purpose for which it is then being used, this Lease
shall terminate and the rent shall be abated during the unexpired portion of
this Lease effective on the date physical possession is taken by the
condemning authority.  Tenant shall have no claim to the condemnation award
or proceeds in lieu thereof, except that Tenant shall be entitled to a
separate award for the cost of relocating its business, and damage to and
removing and moving of its personal property.

8.2 PARTIAL TAKING.  If all or a substantial part of the Premises are taken
for any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain or by purchase in lieu thereof, and
this Lease is not terminated as provided in Section 8.1 above, the rent
payable under this Lease during the unexpired portion of the term shall be
adjusted to such an extent as may be fair and reasonable under the
circumstances.  Tenant shall have no claim to the condemnation award or
proceeds in lieu thereof, except that Tenant shall be entitled to a separate
award for the cost of relocating its business, and damage to and removing and
moving its personal property.

                     ARTICLE 9. ASSIGNMENT OR SUBLEASE

9.1 LANDLORD ASSIGNMENT.  Landlord shall have the right to sell, transfer or
assign, in whole or in part, its rights and obligations under this Lease and
in the Building.  Any such sale, transfer or assignment shall operate to
release Landlord from any and all liabilities under this Lease arising after
the date of such sale, assignment or transfer.

9.2 TENANT ASSIGNMENT.  Tenant shall not assign, in whole or in part, this
Lease, or allow it to be assigned, in whole or in part, by operation of law
or otherwise (including without limitation by transfer of a majority interest
of stock, merger, or dissolution, which transfer of majority interest of
stock, merger or dissolution shall be deemed an assignment) or mortgage or
pledge the same, or sublet the Premises, in whole or in part, without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld, and in no event shall said such assignment or sublease ever release
Tenant or any guarantor from any obligation or liability hereunder.
Notwithstanding anything in this Lease to the contrary, in the event of any
assignment

                                      -3-
<PAGE>

or sublease, any option or right of first refusal granted to Tenant shall not
be assignable by Tenant to any assignee or sublessee.  No assignee or
sublessee of the Premises or any portion thereof may assign or sublet the
Premises or any portion thereof.

9.3 CONDITIONS OF ASSIGNMENT.  If Tenant desires to assign or sublet all or
any part of the Premises, it shall so notify Landlord at least thirty (30)
days in advance of the date on which Tenant desires to make such assignment
or sublease.  Tenant shall provide Landlord with a copy of the proposed
assignment or sublease and such information as Landlord might request
concerning the proposed sublessee or assignee to allow Landlord to make
informed judgments as to the financial condition, reputation, operations and
general desirability of the proposed sublessee or assignee.  Within fifteen
(15) days after Landlord's receipt of Tenant's proposed assignment or
sublease and all required information concerning the proposed sublease or
assignee, Landlord shall have the following options:  (1) cancel this Lease
as to the Premises or portion thereof proposed to be assigned or sublet; (2)
consent to the proposed assignment or sublease, and, if the rent due and
payable by any assignee or sublessee under any such permitted assignment or
sublease (or a combination of the rent payable under such assignment or
sublease plus any bonus or any other consideration or any payment incident
thereto) exceeds the rent payable under this Lease for such space, Tenant
shall pay to Landlord all such excess rent and other excess consideration
within ten (10) days following receipt thereof by Tenant; or (3) refuse to
consent to the proposed assignment or sublease, which refusal shall be deemed
to have been exercised unless Landlord gives Tenant written notice providing
otherwise.  Upon the occurrence of an event of default, if all or any part of
the Premises are then assigned or sublet, Landlord, in addition to any other
remedies provided by this Lease or provided by law, may, at its option,
collect directly from the assignee or sublessee all rents becoming due to
Tenant by reason of the assignment or sublease.  Any collection directly by
Landlord from the assignee or sublessee shall not be construed to constitute
a novation or a release of Tenant or any guarantor from the further
performance of its obligations under this Lease.

9.4 RIGHTS OF MORTGAGE.  Tenant accepts this Lease subject and subordinate to
any recorded mortgage presently existing or hereafter created upon the
Building and to all existing recorded restrictions, covenants, easements and
agreements with respect to the Building.  Landlord is hereby irrevocably
vested with full power and authority to subordinate Tenant's interest under
this Lease to any first mortgage lien hereafter placed on the Premises, and
Tenant agrees upon demand to execute additional instruments subordinating
this Lease as Landlord may require.  If the interests of Landlord under this
Lease shall be transferred by reason of foreclosure or other proceedings for
enforcement of any first mortgage or deed of trust on the Premises, Tenant
shall be bound to the transferee (sometimes called the "Purchaser") at the
option of the Purchaser, under the terms, covenants and conditions of this
Lease for the balance of the term remaining, including any extensions or
renewals, with the same force and effect as if the Purchaser were Landlord
under this Lease, and, if requested by the Purchaser, Tenant agrees to attorn
to the Purchaser, including the first mortgagee under any such mortgage if it
be the Purchaser, as its Landlord. Notwithstanding the foregoing, Tenant
shall not be disturbed in its possession of the Premises so long as Tenant is
not in default hereunder.

9.5 TENANT'S STATEMENT.  Tenant agrees to furnish, from time to time, within
ten (10) days after receipt of a request from Landlord or Landlord's
mortgagee, a statement certifying, if applicable, the following:  Tenant is
in possession of the Premises; the Premises are acceptable; the Lease is in
full force and effect; the Lease is unmodified; Tenant claims no present
charge, lien, or claim or offset against rent; the rent is paid for the
current month, but is not prepaid for more than one month and will not be
prepaid for more than one month in advance; there is no existing default by
reason of some act or omission by Landlord; and such other matters as may be
reasonably required by Landlord or Landlord's mortgagee.  Tenant's failure to
deliver such statement, in addition to being a default under this Lease,
shall be deemed to establish conclusively that this Lease is in full force
and effect except as declared by Landlord, that Landlord is not in default of
any of its obligations under this Lease, and that Landlord has not received
more than one month's rent in advance.  Tenant agrees to furnish, from time
to time, within ten (10) days after receipt of a request from Landlord, a
current financial statement (10-Q or 10-K) of Tenant, certified as true and
correct by Tenant.

   ARTICLE 10. LANDLORD'S LIEN AND SECURITY AGREEMENT  (Intentionally omitted)

                      ARTICLE 11. DEFAULT AND REMEDIES

11.1 DEFAULT BY TENANT.  The following shall be deemed to be events of
default ("Default") by Tenant under this Lease:  (1) Tenant shall fail to
pay when due any installment of rent or any other payment required pursuant
to this Lease and such failure is not cured within three (3) days following
written notice to Tenant;  (2) Tenant shall abandon any substantial portion
of the Premises; (3) Tenant shall fail to comply with any term, provision or
covenant of this Lease, other than the payment of rent, and the failure is
not cured within twenty (20) days after written notice to Tenant or such
longer period as is reasonably required to cure, provided that Tenant is
diligently pursuing the same; (4) Tenant shall file a petition or if an
involuntary petition is filed against Tenant and is not discharged within
thirty (30) days, or becomes insolvent, under any applicable federal or state
bankruptcy or insolvency law or admit that it cannot meet its financial
obligations as they become due; or a receiver or trustee shall be appointed
for all or substantially all of the assets of Tenant; or Tenant shall make a
transfer in fraud of creditors or shall make an assignment for the benefit of
creditors; or (5) Tenant shall do or permit to be done any act which results
in a lien being filed against the Premises or the Building and/or project of
which the Premises are a part, which is not discharged within ten (10) days
following written notice to Tenant.

In the event that an order for relief is entered in any case under Title 11,
U.S.C. (the "Bankruptcy Code") in which Tenant is the debtor and:  (A)
Tenant as debtor-in-possession, or any trustee who may be appointed in the
case (the "Trustee") seeks to assume the lease, then Tenant, or Trustee if
applicable, in addition to providing adequate assurance described in
applicable provisions of the Bankruptcy Code, shall provide adequate
assurance to Landlord of Tenant's future performance under the Lease by
depositing with  Landlord a sum equal to the lesser of twenty-five percent
(25%) of the rental and other charges due for the balance of the Lease term
or six (6) months' rent ("Security"), to be held (without any allowance for
interest thereon) to secure Tenant's obligation under the Lease, and (B)
Tenant, or Trustee if applicable, seeks to assign the Lease after assumption
of the same, then Tenant, in addition to providing adequate assurance
described in applicable provisions of the Bankruptcy Code, shall provide
adequate assurance to Landlord of the proposed assignee's future performance
under the Lease by depositing with Landlord a sum equal to the Security to be
held (without any allowance or interest thereon) to secure performance under
the Lease.  Nothing contained herein expresses or implies, or shall be
construed to express or imply, that Landlord is consenting to assumption
and/or assignment of the Lease by Tenant, and Landlord expressly reserves all
of its rights to object to any assumption and/or assignment of the Lease.
Neither Tenant nor any Trustee shall conduct or permit the conduct of any
"fire", "bankruptcy", "going out of business" or auction sale in or
from the Premises.

11.2 REMEDIES FOR TENANT'S DEFAULT.  Upon the occurrence of a Default as
defined above, Landlord may elect either (i) to cancel and terminate this
Lease and this Lease shall not be treated as an asset of Tenant's bankruptcy
estate, or (ii) to terminate Tenant's right to possession only without
cancelling and terminating Tenant's continued liability under this Lease.
Notwithstanding the fact that initially Landlord elects under (ii) to
terminate Tenant's right to possession only, Landlord shall have the
continuing right to cancel and terminate this Lease by giving three (3) days'
written notice to Tenant of such further election, and shall have the right
to pursue any remedy at law or in equity that may be available to Landlord.

In the event of election under (ii) to terminate Tenant's right to possession
only, Landlord may, at Landlord's option, enter the Premises and take and
hold possession thereof, without such entry into possession terminating this
Lease or releasing Tenant in whole or in part from Tenant's obligation to pay
all amounts hereunder for the full stated term.  Upon such reentry, Landlord
may remove all persons and property from the Premises and such property may
be removed and stored in a public warehouse or elsewhere at the cost and for
the account of Tenant, without becoming liable for any loss or damage which
may be occasioned thereby.  Such reentry shall be conducted in the following
manner:  without resort to judicial process or notice of any kind if Tenant
has abandoned or voluntarily surrendered possession of the Premises; and,
otherwise, by resort to judicial process.  Upon and after entry into
possession without termination of the Lease, Landlord may exercise reasonable
efforts to relet the Premises, or any part thereof, to any one other than the
Tenant, for such time and upon such terms as Landlord, in Landlord's sole
discretion, shall determine.  Landlord may make alterations and repairs to
the Premises to the extent deemed by Landlord necessary or desirable to relet
the Premises.

    Upon such reentry, Tenant shall be liable to Landlord as follows:

    A. For all attorneys' fees incurred by Landlord in connection with
       exercising any remedy hereunder;

    B. For the unpaid installments of base rent, additional rent or other
       unpaid sums which were due prior to such reentry, including interest
       and late payment fees, which sums shall be payable immediately.

    C. For the installments of base rent, additional rent, and other sums
       falling due pursuant to the provisions of this Lease for the period
       after reentry during which the Premises remain vacant, including late
       payment charges and interest, which sums shall be payable as they
       become due hereunder.

    D. For all expenses incurred in releasing the Premises, including leasing
       commissions, attorneys' fees, and costs of alteration or repairs, which
       shall be payable by Tenant as they are incurred by Landlord; and

    E. While the Premises are subject to any new lease or leases made
       pursuant to this Section, for the amount by which the monthly
       installments payable under such new lease or leases is less than
       the monthly installment for all charges payable pursuant to this
       Lease, which deficiencies shall be payable monthly.

Notwithstanding Landlord's election to terminate Tenant's right to possession
only, and notwithstanding any reletting without termination, Landlord, at any
time thereafter, may elect to terminate this Lease, and to recover (in lieu
of the amounts which would thereafter be payable pursuant to the foregoing,
but not in diminution of the amounts payable as provided above before
termination), as damages for loss of bargain and not as a penalty, an
aggregate sum equal to the present value of the amount by which the rental
value of the portion of the term unexpired at the time of such election is
less than an amount equal to the unpaid base rent, percentage rent, and
additional rent and all other charges which would have been payable by Tenant
for the unexpired portion of the term of this Lease, which deficiency and all
expenses incident thereto, including commissions, attorneys' fees, expenses
of alterations and repairs, shall be due to Landlord as of the time Landlord
exercises said election, notwithstanding that the term had not expired.  If
Landlord, after such reentry, leases the Premises, then the rent payable


                                      -4-

<PAGE>

under such new lease shall be conclusive evidence of the rental value during
that part of the unexpired portion of the term of this Lease.

If this Lease shall be terminated by reason of bankruptcy or insolvency of
Tenant, Landlord shall be entitled to recover from Tenant or Tenant's estate,
as liquidated damages for loss of bargain and not as a penalty, the amount
determined by the immediately preceding paragraph.

11.3 LANDLORD'S RIGHT TO PERFORM FOR ACCOUNT OF TENANT.  If Tenant shall be
in Default under this Lease, Landlord may cure the Default at any time for
the account and at the expense of Tenant.  If Landlord cures a Default on the
part of Tenant, Tenant shall reimburse Landlord upon demand for any amount
expended by Landlord in connection with the cure, including, without
limitation, attorneys' fees and interest.

11.4 INTEREST, ATTORNEY'S FEES AND LATE CHARGE.  In the event of a Default by
Tenant:  (1) if a monetary default, interest shall accrue on any sum due and
unpaid at the rate of the lesser of Prime plus 4% per annum or the highest
rate permitted by law and, if Landlord places in the hands of an attorney the
enforcement of all or any part of this Lease, the collection of any rent due
or to become due or recovery of the possession of the Premises, Tenant agrees
to pay Landlord's costs of collection, including reasonable attorney's fees
for the services of the attorney, as awarded by a court of competent
jurisdiction.  Other remedies for nonpayment of rent notwithstanding, if the
monthly rental payment or any other payment due from Tenant to Landlord is
not received by Landlord on or before the third (3rd) day after written
notice that the rent is unpaid, a late payment charge of five percent (5%) of
such past due amount shall become due and payable in addition to such amounts
owed under this Lease.

11.5 ADDITIONAL REMEDIES, WAIVERS, ETC.

     A. The rights and remedies of Landlord set forth herein shall be in
        addition to any other right and remedy now and hereafter provided by
        law. All rights and remedies shall be cumulative and not exclusive of
        each other.  Landlord may exercise its rights and remedies at any
        times, in any order, to any extent, and as often as Landlord deems
        advisable without regard to whether the exercise of one right or
        remedy precedes, concurs with or succeeds the exercise of another.

     B. A single or partial exercise of a right or remedy shall not preclude
        a further exercise thereof, or the exercise of another right or remedy
        from time to time.

     C. No delay or omission by Landlord in exercising a right or remedy
        shall exhaust or impair the same or constitute a waiver of, or
        acquiesce to, a Default.

     D. No waiver of Default shall extend to or affect any other Default or
        impair any right or remedy with respect thereto.

     E. No action or inaction by Landlord shall constitute a waiver of
        Default.

     F. No waiver of a Default shall be effective unless it is in writing and
        signed by Landlord.

                  ARTICLE 12. RELOCATION  (Intentionally omitted)

                ARTICLE 13. AMENDMENT AND LIMITATION OF WARRANTIES

         default in performance of its obligations under the Lease, at
         anytime prior to the expiration of lease month forty-two (42).  If
         not timely and properly exercised, this option will automatically

         and conditions as are contained in this Lease, except for base rent,
         which shall be adjusted as hereinafter provided, and Tenant's pro

         base rent for the original Premises) shall equal the sum of the
         following:

              per square foot), which amortization shall be at a rate of nine

         iii. The amortized cost per square foot of unamortized tenant
              improvements located in the expansion premises prior to tenant's
              occupancy, based upon a nine percent (9%) rate and a useful life
              of eight (8) years; the amortization of these costs shall be at
              a rate of nine percent (9%) over the remaining term of the Lease.

      E. The expansion premises shall be delivered to Tenant no earlier than
         the commencement of lease month forty-nine (49) and no later than the
         expiration of lease month sixty (60), with the timing of said delivery
         to be determined by Landlord. Landlord shall provide at least thirty
         (30) days advance written notice of the delivery date.

      F. Upon exercise of this option by Tenant, Landlord and Tenant shall

Licensor maintenance services relating to the Rendering Engine portion only
of the Software (hereinafter more fully described and defined as the
"Maintenance Services") upon the terms and conditions set forth in this
Article VII.  Such option shall be exercised by Licensee by the giving of
prior written notice to Licensor specifying that Licensee wishes to receive
Maintenance Services.  Licensee's option to receive Maintenance Services
pursuant to this Article VII shall expire and become null and void thirty
(30) days following expiration of the Warranty Period if such right had not
previously been exercised by Licensee.

2.    MAINTENANCE SERVICES.  Licensor shall provide Maintenance Services to
Licensee only if Licensee has exercised its option to receive Maintenance
Services in accordance with Section 1 of this Article VII.  Such Maintenance
Services shall consist of consulting services and error correction services.
Such services are referred to herein as the "Maintenance Services."  Solely
for the purposes of Sections 2 and 3 of this Article VII, the term "Software"
shall mean only the Rendering Engine portion of the Software.  Error
correction services provided by Licensor shall consist of any necessary
changes made to the Source Code, as originally delivered to Licensee, in
order to correct or remove any bug, malfunction or other defect that prevents
the Software from performing in accordance with the Functional
Specifications.  In the event Licensee detects any error, defect or
nonconformity in the Software, Licensor shall furnish off-site telephone
support, in the form of consultations, assistance and advice on the use or
maintenance of the Software, within twenty-four (24) hours of Licensee's
request therefor.  In the event that such problem in the Software is not
corrected within seventy-two (72) hours of initiation of such off-site
telephone support, Licensee shall submit to Licensor a listing of the output
and all such other data that Licensor may reasonably request in order to
reproduce operating conditions similar to those present when the error,
defect or nonconformity was discovered.  In the event that such problem is
not corrected within five (5) business days after Licensor receives from
Licensee a listing of output and other data, Licensor shall within the next
seventy-two (72) hours provide on-site service.

3.    RESPONSIBILITIES OF LICENSEE.  Licensee shall notify Licensor
immediately following the discovery of any error, defect or nonconformity in
the Software. The periods within which Licensor is obligated herein to
provide support shall not commence until such time as Licensor receives
notification of such error, defect or nonconformity from Licensee.  Licensee,
upon detection of any error, defect or nonconformity in the Software shall,
if requested to do so by Licensor, submit to Licensor a listing of output and
any such other data that Licensor may reasonably request in order to
reproduce operating conditions similar to those present when the error
occurred or the defect or nonconformity was discovered, as the case may be.

4.    MAINTENANCE FEES.  In consideration for the Maintenance Services,
Licensee shall pay Licensor a monthly fee of $5,000.00 (payable on or before
the 15th of each calendar month during which services are to be rendered to
Licensee by Licensor).

5.    TERM.  Subject to Article XI hereof, in the event Licensee exercises
its option to receive Maintenance Services with respect to the Rendering
Engine, Licensor will render Maintenance Services for the Rendering Engine
for a period of one year.  Thereafter, Licensor's obligations to render
Maintenance Services for the Rendering Engine, and Licensee's obligations to
pay for such services, shall automatically be renewed for an additional
period of one year; provided, however, that either party may prevent the
automatic renewal of such obligations by written notice to the other given at
least thirty (30) days prior to expiration of the initial one-year term set
forth in the preceding sentence.

6.    ENHANCEMENTS.  Licensor may from time to time make enhancements to the
Software.  Any such enhancements shall be owned by Licensor, but any
enhancements made by Licensor during such time as Licensee is paying Licensor
a maintenance fee under this Article VII shall be made available to Licensee,
at no additional cost, and shall be subject to the terms and conditions of
this Agreement; provided, however, that Licensee has fully complied with all
the terms and conditions of this Agreement.

      annual Maintenance Contract has three months left on its term, then
      Licensee will be entitled to a credit for 25% of Licensor's share of such
      maintenance fees as such share is determined pursuant to the Marketing

      b.  ASSIGNMENT AND ASSUMPTION.  Licensor hereby assigns to Licensee all of
      Licensor's right, title and interest in and to the Existing Licenses and

      the remaining terms of the Existing Licenses and the Existing Maintenance

      that any Existing License or Existing Maintenance Contract for which
      assignment to Licensee is provided herein is not assignable without the
      consent of another party, this Agreement shall not constitute an
      assignment or an attempted assignment thereof if such assignment of
      attempted assignment would constitute a breach thereof.  Licensor and

      of such other party to the assignment of any such Existing License and/or
      Existing Maintenance Contract to Licensee in all cases in which such
      consent is or may be required for such assignment.  If any such consent
      shall not be obtained, Licensor agrees to cooperate with Licensee in any
      reasonable arrangement designed to provide for Licensee the benefits
      intended to be assigned to Licensee under the relevant Existing License or
      Existing Maintenance Contract, including enforcement, at the cost and for
      the account of Licensee, of any and all rights of Licensor against the
      other party thereto arising out of the breach or cancellation thereof by
      such other party or otherwise.  If and to the extent that such arrangement
      cannot be made, Licensee, upon notice to Licensor, shall have no
      obligation with respect to any such Existing License and/or Existing
      Maintenance Contract, as the case may be, and any such Existing License
      and/or Existing Maintenance Contract shall not be deemed to have been

      amount equal to the unearned portion of fees previously collected by
      Licensor from CDDI members.

      b.  ASSIGNMENT AND ASSUMPTION.  Licensor hereby assigns to Licensee all of
      Licensor's right, title and interest in and to the CDDI Agreements and
      Licensee hereby accepts such assignment.  Licensee hereby further assumes
      and agrees to be bound by all the remaining terms of the CDDI Agreements
      as if Licensee was an original party thereto.  To the extent that any CDDI
      Agreement for which assignment to Licensee is provided herein is not

      constitute an assignment or an attempted assignment thereof if such
      assignment of attempted assignment would constitute a breach thereof.
      Licensor and Licensee agree to use their reasonable best efforts to
      obtain the consent of such other party to the assignment of any such CDDI
      Agreement to Licensee in all cases in which such consent is or may be

(collectively the "Subject Products"), which Agreement was amended by that
certain Amendment effective as of September 25, 1985, and also amended by
that certain Amendment No. 2 effective as of July 31, 1985 (such Agreement as
amended is referred to hereafter as the "Acquisition Agreement").

THIRD.  Bioplasty and the Buyer entered into that certain License Agreement
dated as of September 25, 1985, which restated and clarified the grant of an
exclusive license to the Buyer to use, manufacture, apply, sell, market and
commercialize the Subject Products in consideration for payment by the Buyer

during the 10-year term of the License Agreement, which Agreement was amended
by that certain Amendment to License Agreement between Bioplasty and the

dated as of February 17, 1986 (the "Purchase Agreement") (the Acquisition
Agreement, the License Agreement and the Purchase Agreement are referred to

1.  REPRESENTATIONS, WARRANTIES, AND COVENANTS OF THE SELLERS.  The Sellers
hereby, jointly and severally, represent, warrant, and covenant to the Buyer
as follows:

      (a)  ORGANIZATION.  Both Bioplasty and Uroplasty have been duly
      organized and are validly existing and in good standing under the laws
      of the State of Minnesota.

      (b)  EXECUTION AND AUTHORITY; ABSENCE OF CONFLICTS.  This Agreement
      and all other documents executed or to be executed by or on behalf of

<PAGE>

      will constitute valid and binding obligations of the Sellers,
      enforceable (subject to usual equity principles) in accordance with
      their terms (subject, as to enforcement of remedies, to applicable
      bankruptcy, insolvency, moratorium, or other laws affecting creditors'
      rights generally).  The sale by the Sellers of the 589 Patent
      hereunder and the performance of the transactions contemplated hereby
      will not conflict with or result in the breach of any of the terms or
      provisions of any note, mortgage, loan agreement, or other agreement
      or instrument to which either of the Sellers is a party or by which
      either of the Sellers may be bound or any statute or order, rule, or
      regulation applicable to either of the Sellers.  No consent, approval,
      authorization, registration, or qualification of or with any court,
      regulatory agency, governmental body, or third person is required for
      the sale of the 589 Patent and the performance of the transactions
      contemplated by this Agreement.

      (c)  LITIGATION.  As of the Closing Date, the Sellers have no actual
      knowledge of (and do not undertake any obligation to determine the
      existence of) any litigation or proceeding, pending or threatened,
      contemplated against or relating to either of the Sellers or the 589
      Patent by or before any court, arbitrator, or federal, state or other
      governmental commission, board, or other agency, that would have a
      material adverse affect on the 589 Patent.

      (d)  589 PATENT.  As of the Closing Date, Uroplasty has good and
      marketable title to the 589 Patent (except to the extent that neither
      the Patent Assignment nor the name change of Bioplasty have been filed
      with the United States Patent and Trademark Office) and shall transfer
      title to the 589 Patent to the Buyer free and clear of all mortgages,
      pledges, liens, conditional sales agreements, or other encumbrances of
      any kind or nature whatsoever.  The Sellers, collectively, have the
      sole right to sell the 589 Patent and have not, jointly or severally,
      heretofore sold or granted any rights in the 589 Patent to any third
      party.

      (e)  INFRINGEMENT.  As of the Closing Date, the Sellers have no actual
      knowledge of (and do not undertake any obligation to determine the
      existence of) any facts or circumstances from which it could be
      reasonably concluded that the 589 Patent materially infringes on any
      patent, copyright, trademark, trade secret or other proprietary right
      of any third party, nor any facts or circumstances from which it could
      reasonably conclude that a third party is infringing the 589 Patent.

      (f)  FOREIGN PATENTS.  With respect to the 589 Patent, as of the
      Closing Date, the Sellers have no actual knowledge of (and do not
      undertake any obligation to determine the existence of) any facts or
      circumstances from which it could reasonably conclude that there are
      any corresponding equivalent foreign patents, related foreign patents,
      or any continuation or reissue foreign patents, or other variations to
      or of the subject invention (collectively, "Foreign Patents").  The
      Sellers shall, to the extent reasonably requested by the Buyer and at
      Buyer's sole expense, assist the Buyer in the procurement of any
      Foreign Patents.

      (g)  RELIANCE.  The foregoing representations, warranties, and
      covenants are made by the Sellers with the knowledge and expectation
      that the Buyer is relying thereon.

      principles) in accordance with their terms (subject, as to enforcement
      of remedies, to applicable bankruptcy, insolvency, moratorium, or
      other laws affecting creditors' rights generally).  The purchase by
      the Buyer of the 589 Patent hereunder and the performance of the

      (c)  LITIGATION.  As of the Closing Date, the Buyer has no actual
      knowledge of (and does not undertake any obligation to determine the

      court, arbitrator or federal, state or other governmental commission,
      board or agency, that would have a material adverse effect on the 589
      Patent.

      Closing Date, the Buyer has no actual knowledge of (and does not
      undertake any obligation to determine the existence of) any facts or
      circumstances from which it could reasonably conclude that there are
      any corresponding equivalent foreign patents, related foreign patents
      or any continuation or reissue foreign patents or any other variations
      to or of the subject invention.

      (f)  VALIDITY OF THE 589 PATENT.  The Buyer waives any claim it may

4.  INDEMNIFICATION.  In addition to the indemnification set forth in Article
II, Section 3, the Sellers, jointly and severally, agree to indemnify and
hold harmless the Buyer from and against any and all (i) liabilities,

particularity the nature and extent of such waiver, modification, or amendment.
Any waiver by any party of any provision hereof shall not affect or impair any

accordance with the laws of the State of Minnesota.
