ITEM 1.  BUSINESS:

     Certain of the information contained in this Form 10-K, including the
discussion which follows in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" found in Item 7 of this Report, contain
forward-looking statements.  For a discussion of important factors that could
cause actual results to differ materially from such forward-looking statements,
carefully review this Report, including Exhibit 99.1 hereto, as well as other
information contained in Arrow International, Inc.'s periodic reports filed with
the Securities and Exchange Commission (the "SEC" or "Commission").

     Arrow International, Inc. (together with its subsidiaries, "Arrow" or the
"Company") was incorporated as a Pennsylvania corporation in 1975.  Arrow
develops, manufactures and markets a broad range of clinically advanced,
disposable catheters and related products for critical and cardiac care.  The
Company's critical care products are used principally for central vascular
access for administration of fluids, drugs, and blood products, patient
monitoring and diagnostic purposes, as well as for pain management.  These
products are used by anesthesiologists, critical care specialists, surgeons,
cardiologists, nephrologists, emergency and trauma physicians and other health
care providers.  Arrow's cardiac care products are used by interventional
cardiologists, interventional radiologists and electrophysiologists for such
purposes as the diagnosis and treatment of heart and vascular disease and to
provide short-term cardiac assist following cardiac surgery, serious heart
attack or balloon angioplasty.

     Arrow's critical care products, which were originally introduced in 1977,
accounted for 84.3%, 84.4% and 82.2% of net sales in fiscal 1998, 1997 and 1996,
respectively.  The majority of these products are vascular access catheters and
related devices which consist principally of the following:  the Arrow-Howes(TM)
Multi-Lumen Catheter, a catheter equipped with three or four channels that
enables the simultaneous administration of multiple critical care therapies
through a single puncture site; double-and single-lumen catheters, which are
designed for use in a variety of clinical procedures; the ARROWg+ard(TM)
antiseptic surface treatment, which is applied to many of the Company's vascular
access catheters to reduce the risk of catheter-related infection; percutaneous
sheath introducers, which are used as a means for inserting cardiovascular and
other catheterization devices into the vascular system during critical care
procedures; radial artery catheters, which are used for measuring arterial blood
pressure and taking blood samples; and FlexTip Plus(TM) epidural catheters,
which are designed to minimize indwelling complications associated with
conventional epidural catheters.

     In April 1995, the Company expanded its critical care product line by
acquiring Therex Limited Partnership ("Therex"), a company engaged in the
development, manufacture and marketing of implantable constant flow drug
delivery pumps and a broad line of implantable vascular access ports used for
the infusion of certain drugs over an extended period of time in connection with
the treatment of cancer, other chronic diseases and chronic pain.  The Company
received Food and Drug Administration ("FDA") marketing clearance in March 1996
for its Model 3000 Constant Flow Implantable Pump for the administration of the
chemotherapy drug, 2-Deoxy 5-Flourouridine ("FUDR"), for the treatment of liver
cancer.  The Company received additional FDA marketing clearance for the Model
3000 pump for the administration of morphine to treat malignant pain in February
1997 and to treat intractable pain with morphine in September 1997. In July
1997, the Company further expanded its critical care product line by acquiring
the implantable constant flow drug delivery pump product business of
Strato/Infusaid Inc., a former subsidiary of Pfizer, Inc., ("Strato/Infusaid").
In March 1998, the Company received FDA marketing clearance for its Model 3000-
16 constant flow implantable pump for the administration of morphine to treat
benign pain.  In September 1998, the Company received FDA marketing clearance
for its Model 3000 pump for the administration of Baclofen, a drug used for the
treatment of spasticity.

     In August 1997, the Company received FDA marketing clearance for its
Percutaneous Thrombolytic Device ("PTD") which is designed for clearance of
thrombosed hemodialysis

                                      (2)

ITEM 1.  BUSINESS (CONTINUED):

grafts in chronic hemodialysis patients.  This mechanical rotating device,
patented by Johns Hopkins University and exclusively licensed by the Company,
has shown effective graft de-clotting results in a 122 patient human clinical
trial, when compared with a commonly used thrombolysis method for dissolving
these clots.  The Company believes that this device provides a cost-effective
alternative means for clearing these grafts, which occur an average of once each
year in a large percentage of the estimated 185,000 U.S. patients currently
undergoing chronic hemodialysis treatment.

     In August 1998, the Company strengthened its ability to meet the needs of
critical care physicians by acquiring Medical Parameters, Inc.  Medical
Parameters, Inc. manufactures and markets custom tubing sets used by critical
care physicians to connect central venous catheters to blood pressure monitoring
devices and drug infusion systems.

     Arrow's cardiac care products accounted for 15.7%, 15.6% and 17.5% of net
sales in fiscal 1998, 1997 and 1996, respectively.  These products include
cardiac assist products, such as intra-aortic balloon pumps and catheters ("IAB
products"), which are used primarily to augment temporarily the pumping
capability of the heart following cardiac surgery, serious heart attack or
balloon angioplasty; electrophysiology products, such as pacing and mapping
catheters, which are used primarily to provide temporary pacing of the heart and
to map the electrical signals which activate the heart; the Berman(TM)
Angiographic Catheter, which is used for pediatric cardiac angiographic
procedures; and other cardiac care products, such as the Super Arrow-Flex(TM)
sheath, which provides a kink-resistant passageway for the introduction of
cardiac and other catheters into the vascular system.  The Company entered the
cardiac care market in 1987 through the purchase of certain assets from
Critikon, Inc. and, in February 1994, expanded into the field of cardiac assist
by acquiring the intra-aortic balloon pump and catheter business of Kontron
Instruments, Inc. ("Kontron Instruments").

     In November 1997, the Company continued the expansion by acquiring the
Cardiac Assist Division of the Boston Scientific Corporation, a manufacturer and
marketer of intra-aortic balloon catheters and an intra-aortic balloon pump.  In
January 1998, the Company received clearance from the FDA to market the
Company's new ACAT(TM)1 intra-aortic balloon pump in the U.S.  The ACAT(TM)1 is
smaller, lighter and more technologically advanced than the KAAT II Plus (R)
pump, which it replaces, and represents the current state-of-the art in intra-
aortic balloon pumping.

     The Company received FDA marketing clearance in May 1996 for its Narrow-
Flex(TM) reduced diameter (8 Fr.) intra-aortic balloon catheter based on new,
patented construction technology.  The Company believes this catheter is the
smallest available with full 40cc balloon augmentation capability, the same
degree of heart pumping augmentation that previously had been available only
through the use of larger diameter catheters.  This smaller diameter catheter
takes up less space in the femoral artery than previously available catheters
and, therefore, is designed to improve blood circulation to the lower
extremities.  Reduced blood flow to the leg is a major complication of intra-
aortic balloon pumping.

     In March 1995, the Company extended its line of electrophysiology products
by entering into agreements with Cardiac Pathways Corporation ("Cardiac
Pathways") for certain distribution and manufacturing rights to Cardiac
Pathways' Trio/Ensemble(TM) mapping catheter system used for the diagnosis of
certain cardiac tachyarrhythmias (conditions involving abnormal, potentially
life-threatening electrical signals in the heart).  The Company's distribution
rights are worldwide, with the exception of Japan and certain countries in
Europe, where Cardiac Pathways had distribution arrangements already in place.
The Company received FDA marketing clearance for the Trio/Ensemble(TM) mapping
catheter system in December 1995 and currently sells this product in the U.S.
In connection with these agreements, the Company also acquired an equity
interest in Cardiac Pathways, representing approximately 6.2% of the currently
outstanding common stock of Cardiac Pathways.

ITEM 1.  BUSINESS (CONTINUED):

     SALES AND MARKETING

     Arrow markets its products to physicians and hospitals through a
combination of direct selling and independent distributors. Within each
hospital, marketing efforts are targeted to those physicians, including critical
care specialists, cardiologists, anesthesiologists, interventional radiologists,
electrophysiologists and surgeons, most likely to use the Company's products.
Arrow's products are generally sold in the form of pre-sterilized procedure kits
containing the catheters and virtually all of the related medical components and
accessories needed by the clinician to prepare for and perform the intended
medical procedure. Additional sales revenue is derived from equipment provided
for use in connection with certain of the Company's disposable products.

     In fiscal 1998, 1997 and 1996, 64.9%, 63.8% and 61.8%, respectively, of the
Company's net sales were to U.S. customers.  In this market, approximately 79.0%
of the Company's fiscal 1998 revenue was generated by its direct sales force.
The remainder resulted from shipments to independent distributors.  For the
majority of such distributors, the Company's products represent a principal
product line.  Direct selling generally generates higher gross profit margins
than sales made through independent distributors.

     Internationally, the Company sells its products through eleven direct sales
subsidiaries serving markets in Japan, Germany, the Netherlands, France, Spain,
Greece, Africa, Canada, Mexico, the Czech Republic and Slovakia.  As of November
2, 1998, independent distributors in 79 additional countries service the
remainder of the world.

     To support growth in international sales, the Company operates a 40,000
square foot manufacturing facility in Chihuahua, Mexico and, in January 1996,
completed construction of a 65,000 square foot manufacturing and research
facility in the Czech Republic, which began shipments in the fourth quarter of
fiscal 1996.

     Revenues, profitability and identifiable assets attributable to significant
geographic areas are presented in Note 13 to the Company's consolidated
financial statements, included herein.

     In general, Arrow does not produce against a backlog of customer orders;
production is based primarily on the level of inventories of finished products
and projections of future customer demand with the objective of shipping from
stock upon receipt of orders.  No single customer accounts for a material part
of the Company's sales.  Usage of the Company's products by hospitals and
physicians has not been materially influenced by seasonal factors.

     Rapid growth in U.S. health care costs, coupled with a lack of access by
some U.S. citizens to adequate health care, has resulted in numerous legislative
initiatives in the U.S. Congress during the last several years.  While none of
these initiatives have to date resulted in substantive legislation, the intent
of these initiatives was, generally, to expand health care coverage for the
uninsured and reduce the rate of growth of total health care expenditures.  In
addition, certain states have made significant changes to their Medicaid
programs and have adopted various measures to expand coverage and limit costs.
Implementation of government health care reform and other efforts to control
costs may limit the price of, or the level at which reimbursement is provided
for, the Company's products.  The increased emphasis in the U.S. on health care
cost containment has resulted in reduced growth in demand for certain of the
Company's products in markets where Arrow has 80% or greater market shares, and
protecting that market share has affected the Company's pricing in some
instances.  The Company presently believes that this emphasis has increased the
importance of competitive prices and may continue to reduce the U.S. growth rate
for certain of the Company's products.  The Company anticipates that Congress,
state legislatures, foreign governments and the private sector will continue to
review and assess alternative health care delivery and payment

systems.  The Company cannot predict what additional legislation or regulation,
if any, relating to the health care industry may be enacted in the future or
what impact the adoption of any federal, state or foreign health care reform,
private sector reform or market forces may have on its business.  No assurance
can be given that any such reforms will not have a material adverse effect on
the medical device industry in general, or the Company in particular.

     RESEARCH AND PRODUCT DEVELOPMENT

     Arrow is engaged in ongoing research and development to introduce
clinically advanced new products, to enhance the effectiveness, ease of use,
safety and reliability of its existing products and to expand the clinical
applications for which use of its products is appropriate. The principal focus
of the Company's research and development effort is to identify and analyze the
needs of physicians in critical and cardiac care medicine, and to develop
products that address these needs. The Company views ideas submitted by
physicians and other health care professionals as an important source of
potential research and development projects. The Company believes that these
end-users are often in the best position to conceive of new products and to
recommend ways to improve the performance of existing products. Most of the
Company's principal products and product improvements have resulted from
collaborative efforts with physicians, other health care professionals or other
affiliated entities. For certain proprietary ideas, the Company pays royalties
to such persons, and in many instances, incorporates such persons' names in the
tradename or trademark for the specific product. The Company also utilizes other
outside consultants, inventors and medical researchers to carry on its research
and development effort and sponsors research through medical associations and at
various universities and teaching hospitals.

     Certain of the Company's strategic acquisitions and investments have
provided the basis for its introduction of significant new products.  The
Company entered the field of cardiac assist with the acquisition of Kontron
Instruments.  The Company's investment in Cardiac Pathways provided new products
in the field of electrophysiology, and the Company's acquisition of Therex,
augmented by the acquisition of the Strato/Infusaid implantable constant flow
drug delivery pump product line, has provided it with a new product offering of
implantable drug delivery devices, which the Company believes represents an
important addition to its critical care product line.  Where appropriate, the
Company plans to continue to complement its internal research and development
efforts with similar acquisitions and collaborative arrangements.

     Research and development expenses totaled $18.4 million (7.1% of net
sales), $15.9 million (6.5% of net sales) and $14.1 million (6.1% of net sales)
in fiscal 1998, 1997 and 1996, respectively. Such amounts were used to develop
new products, improve existing products and implement new technology to produce
these products.

     Since 1988, the Company has been developing the Arrow-Fischell Pullback
Atherectomy Catheter (the "PAC") for the removal of atherosclerotic plaque.  The
Company acquired certain patents relating to the technology underlying the PAC
in 1990.  In conjunction with the acquisition, the Company entered into a
research and development agreement under which the Company was required to make
certain payments upon the PAC's achievement of specified development milestones.
In July 1995, the Company amended this agreement to modify the terms of payment
of, and recognize as pre-paid royalties, such milestone payments thereunder.
Since December 1994, the Company has been conducting human clinical trials
outside the U.S. using the PAC in coronary arteries and, in March 1995, the
Company received

                                      (5)
<PAGE>
 
ITEM 1.  BUSINESS (CONTINUED):

FDA approval under an Investigational Device Exemption ("IDE") to conduct Phase
I human clinical trials in the U.S. for use of the PAC in treating
atherosclerosis of coronary arteries.  Cardiologists have expressed interest in
using the device for removing plaque at arterial junctions (bifurcations) and
for clearing restenosed stents.  For treatment of coronary arteries, the device
has been used successfully in approximately 164 cases internationally and 60
cases in the U.S. Phase I clinical trials.  In the fourth quarter of 1998, the
Company began a European multi-center randomized study to evaluate the
effectiveness of the PAC for the removal of plaque from restenosed coronary
stents.

     The Company began conducting clinical trials under an IDE in August 1996
for a catheter device, which uses microwave energy for the ablation of cardiac
tissue responsible for ventricular tachycardia. The microwave ablation
catheter's radiative heating mechanism is potentially capable of creating
deeper, wider lesions than currently marketed radio frequency ablation
catheters, which lesions electrophysiologists indicate are necessary for the
effective treatment of ventricular tachycardia using ablation therapy. This
microwave ablation catheter also incorporates several advanced features that are
designed to permit continuous monitoring of catheter/tissue interface
temperature, reduce the risk of tissue overheating and enhance maneuverability
of the catheter to facilitate proper placement in the heart. In June 1996, the
Company acquired additional exclusive, worldwide rights with respect to the
technology underlying its microwave ablation catheter program. Ongoing research
is being conducted on an ablation catheter which uses microwave energy to
eliminate aberrant electrical signals which cause ventricular tachycardia,
atrial flutter and atrial fibrillation arrhythmias. Animal trials, to be
followed by human trials, are underway to determine if microwave energy offers
advantages over currently available catheters utilizing radio frequency energy
for this procedure.

     In January 1994, the Company formed a cooperative relationship with
Pennsylvania State University's Hershey Medical School for the commercial
development of a fully implantable long-term Left Ventricular Assist Device
("LVAD").  Although LVADs are currently used to provide short-term cardiac
assist to patients awaiting heart transplants, the Company's efforts are aimed
at developing a fully implantable device to provide long-term cardiac assist for
patients having insufficient ventricular heart function.  In contrast to
currently marketed LVADs, the LVAD currently under development by the Company is
not intended merely as a bridge to heart transplant, but is designed, upon
receipt of necessary regulatory approvals, to serve as a long-term cardiac
assist device for certain patients.  The Hershey Medical School LVAD has been in
development for over fifteen years and has undergone extensive preclinical
studies and testing.  The LVAD being developed is electrically driven by a
wearable battery pack transmitting power non-invasively through the skin to an
implanted receiving coil that maintains a charge in batteries incorporated into
the device.  These implanted batteries are capable of maintaining LVAD function
for approximately 45 minutes without the aid of any external power source.  In
fiscal 1997, the Company began long-term durability testing of its LVAD, which
must be satisfactorily completed before Phase I human clinical trials under an
IDE can be commenced in the U.S.  In addition, the Company conducted animal
trials in fiscal 1998 and currently anticipates the first human implant of the
device in late 1999.

     There can be no assurance that the FDA or any foreign government regulatory
authority will grant the Company authorization to market products under
development or, if such authorization is obtained, that such products will prove
competitive when measured against other available products.

     ENGINEERING AND MANUFACTURING

     Arrow has developed the core technologies that the Company believes are
necessary for it to design, develop and manufacture complex, high quality
catheter-related medical devices.  This technological capability has enabled the
Company to develop internally many of the major

                                      (6)
<PAGE>
 
ITEM 1.  BUSINESS (CONTINUED):

     ENGINEERING AND MANUFACTURING (CONTINUED)

components of its products and reduce its unit manufacturing costs.  To help
further reduce manufacturing costs and improve efficiency, the Company has
increasingly automated the production of its high-volume products and plans to
continue to make significant capital expenditures to promote efficiency and
reduce operating costs.

     Raw materials and purchased components essential to Arrow's business have
typically been available within the lead times required by the Company and,
consequently, procurement has not historically posed any significant problems in
the operation of the Company's business. Although the Company currently
maintains only one supplier for certain of its out-sourced components, it has
identified alternative vendors for most of these items and, therefore, does not
believe that it is dependent on any single supplier for major raw materials or
components.

     PATENTS, TRADEMARKS, PROPRIETARY RIGHTS AND LICENSES

     Arrow believes that patents and other proprietary rights are important to
its business.  The Company also relies upon trade secrets, know-how, continuing
technological innovations and licensing opportunities to develop and maintain
its competitive position.  Arrow currently holds numerous U.S. patents and
patent applications, as well as several foreign patents and patent applications
which relate to aspects of the technology used in certain of the Company's
products, including its radial artery catheter, percutaneous sheath introducer
and interventional diagnostic catheter products.  There can be no assurance that
patent applications filed by the Company will result in the issuance of patents
or that any patents owned by or licensed to the Company will provide competitive
advantages for the Company's products or will not be challenged or circumvented
by others.

     In addition, Arrow is a party to several license agreements with unrelated
third parties pursuant to which it has obtained, for varying terms, the
exclusive rights to certain patents held by such third parties in consideration
for royalty payments.  Many of the Company's major products, including its
Arrow-Howes(TM) Multi-Lumen Catheters and antiseptic surface treatment for
catheters, have been developed pursuant to such license agreements.  The Company
has in the past granted rights in certain patents relating to its Arrow-
Howes(TM) Multi-Lumen Catheters to others in consideration for royalty payments.
The Company also has certain proprietary rights to aspects of the technology,
including certain U.S. patents, used in the PAC.  See "Research and Product
Development".  All of the existing patents owned by or licensed to the Company
relating to its major products expire after October 2001.  The U.S. patent
licensed to the Company relating to its Arrow-Howes(TM) Multi-Lumen Catheter
expired in February 1995.  Since the expiration of this patent, the Company has
not experienced significant new competition in this market, and the Company does
not presently believe that such competition will have a material adverse effect
on the Company's business, financial condition or results of operations for the
foreseeable future.

     From time to time, the Company is subject to legal actions involving patent
and other intellectual property claims.  Based upon information presently
available to the Company, the Company knows of no legal actions involving patent
claims that are currently pending or threatened against the Company that could
have a material adverse effect on the Company.  Arrow owns a number of
registered trademarks in the United States and, in addition, has obtained
registration in many of its major foreign markets for the trademark ARROW and
certain other trademarks.

ITEM 1.  BUSINESS (CONTINUED):

     GOVERNMENT REGULATION

     As a developer, manufacturer and marketer of medical devices, the Company
is subject to extensive regulation by, among other governmental entities, the
FDA and the corresponding state, local and foreign regulatory agencies in
jurisdictions in which the Company sells its products. These regulations govern
the introduction of new medical devices, the observance of certain standards
with respect to the manufacture, testing and labeling of such devices, the
maintenance of certain records, the tracking of such devices and other matters.
Failure to comply with applicable federal, state, local or foreign laws or
regulations could subject the Company to enforcement action, including product
seizures, recalls, withdrawal of clearances or approvals, and civil and criminal
penalties, any one or more of which could have a material adverse effect on the
Company. In recent years, the FDA has pursued a more rigorous enforcement
program to ensure that regulated businesses, like the Company's, comply with
applicable laws and regulations. The Company believes that it is in substantial
compliance with such governmental regulations. However, federal, state, local
and foreign laws and regulations regarding the manufacture and sale of medical
devices are subject to future changes. No assurance can be given that such
changes will not have a material adverse effect on the Company.

     On occasion, the Company has received notifications, including warning
letters, from the FDA of alleged deficiencies in the Company's compliance with
FDA requirements.  The Company believes that it has been able to address or
correct such deficiencies.  In addition, from time to time the Company has
recalled, or issued safety alerts on, certain of its products.  No such warning
letter, recall or safety alert has had a material adverse effect on the Company,
but there can be no assurance that a warning letter, recall or safety alert
would not have such an effect in the future.

     Like other medical device manufacturers, the Company in recent years has
experienced extended delays in obtaining FDA clearance or approval to market new
products in the U.S.  The FDA review process may continue to delay the Company's
new product introductions in the U.S. in the future.  In addition, many foreign
countries have recently adopted more stringent regulatory requirements which are
expected to add to the delays and uncertainties associated with the release of
new products, as well as the clinical and regulatory costs of supporting such
releases.  It is possible that delays in receipt of, or failure to receive, any
necessary clearance or approval could have a material adverse effect on the
Company's business, financial condition or results of operations.

     COMPETITION

     Arrow faces substantial competition from a number of other companies in the
market for catheters and related medical devices and equipment, including
companies with greater financial and other resources.  In addition, in response
to increased concern about the rising costs of health care, U.S. hospitals and
physicians are placing increasing emphasis on cost-effectiveness in the
selection of products to perform medical procedures.  The Company believes that
its products compete primarily on the basis of product differentiation and
quality and that its comprehensive manufacturing capability enables it to
expedite the development and market introduction of new products and to reduce
manufacturing costs, thereby permitting more effective responses to competitive
pricing in an environment where the Company's ability to increase prices is
limited.

     ENVIRONMENTAL COMPLIANCE

     The Company is subject to various federal, state and local laws and
regulations relating to the protection of the environment.  In the course of its
business, Arrow is involved in the handling, storing and disposal of materials,
which are classified as hazardous.  In June 1989,

ITEM 1.  BUSINESS (CONTINUED):

     ENVIRONMENTAL COMPLIANCE (CONTINUED):

the Company was notified that it was among the potentially responsible parties
under the Federal Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended ("CERCLA"), for the costs of investigating or
remediating contamination at a waste recycling, treatment and disposal facility.
The Company was notified by the U.S. Environmental Protection Agency ("EPA") in
September 1995 of the means by which it may resolve its alleged liability with
respect to the conduct of a remedial investigational feasibility study at this
facility and of the opportunity to participate with other small waste
contributors to this facility in a de minimis settlement which the EPA believes
is likely to be appropriate for this facility.  In December 1995, the Company
indicated its interest in entering into such a de minimis settlement, and this
case has not been active since such date insofar as it involves the Company.

     In November 1991, the EPA made a formal request for information regarding
the nature of the Company's waste that was transported to a municipal landfill,
which is included on the National Priority List under CERCLA.  In October 1997,
the Company received notification from the EPA that it is a potentially
responsible party in connection with environmental contamination at this
landfill.  No determination has yet been made as to allocation of responsibility
for such actions at this landfill.  Previously, in June 1994, the Company,
together with 16 other parties, was named in a complaint filed by a group of
five companies seeking to recover costs incurred as a result of an EPA order
directing such companies to take certain response actions in connection with
this landfill.  Although technically CERCLA imposes strict joint and several
liability for the costs of investigating and remediating certain contaminated
properties, such as this landfill, the extent of each responsible parties'
financial contribution is expected to be based on the number and financial
strength of these parties and the volume and types of waste attributable to each
party.  Although the costs of investigation, study and remediation at this site
may be substantial, the EPA has orally informed the Company that it believes the
Company may be eligible for a de minimis settlement under CERCLA.  EPA has
evaluated information provided to it by the Company and others, which shows that
the volume of materials allegedly transported to the landfill on behalf of the
Company is minor.  The Company expects that the EPA will propose a de minimis
settlement sometime prior to the end of 1998.  If the Company accepts a de
minimis settlement, then it will be afforded contribution protection, and likely
will be dismissed from the private party cost recovery action.  Based on the
foregoing, the Company has concluded that its share of the liability for such
matters will not have a material adverse effect on its business, financial
condition or results of operations.  Therefore, the Company has not accrued any
amounts toward such liability.

     The Company believes that its operations comply in all material respects
with applicable environmental laws and regulations.  While the Company continues
to make capital and operational expenditures for protection of the environment,
it does not anticipate that these expenditures will have a material adverse
effect on its business, financial condition or results of operations.

     PRODUCT LIABILITY AND INSURANCE

     The design, manufacture and marketing of medical devices of the types
produced by the Company entail an inherent risk of product liability.  The
Company's products are often used in intensive care settings with seriously ill
patients.  While the Company believes that, based on claims made against the
Company in the past, the amount of product liability insurance maintained by the
Company has been adequate, there can be no assurance that the amount of such
insurance will be sufficient to satisfy claims made against the Company in the
future or that the Company will be able to obtain insurance in the future at
satisfactory rates or in adequate amounts.

FISCAL 1998 COMPARED TO FISCAL 1997

Net sales increased by $15.0 million, or 6.1%, to $260.9 million in fiscal 1998
from $245.9 million in fiscal 1997. Net sales represent gross sales invoiced to
customers, plus royalty income, less certain related charges, including freight
costs, discounts, returns and other allowances. Sales of critical care products
increased 6.1% to $220.0 million from $207.3 million in fiscal 1997, due
primarily to an increase in unit shipments of central venous catheters,
including increased shipments of ARROWg+ard(TM) Blue(R) antiseptic surface
treated catheter products, pain management catheters, percutaneous thrombectomy
devices ("PTD") and implantable constant flow drug delivery pumps. Sales of
cardiac care products increased 6.5% to $40.9 million from $38.4 million in the
previous year, due primarily to increased shipments of intra-aortic balloon
("IAB") pump and catheter products offset by lower revenue related to
discontinuation of sales of the Thoratec Corporation bi-ventricular assist
device which the Company had been distributing in Europe until July 1, 1997.
International sales increased by $2.4 million, and represented 35.1% of net
sales, excluding royalty income, in fiscal 1998, compared to 36.2% in the prior
year, principally as a result of growth in shipments of IAB pump and catheter
products as well as multi-lumen catheters, offset by the effect of the stronger
U.S. dollar on sales in significant foreign markets and by lower revenue related
to a terminated contract for the sale of Thoratec products. The percentage of
net sales attributable to the Company's direct sales force remained stable in
fiscal 1998 at approximately 74.1% compared to approximately 74.2% in fiscal
1997.

This increase in net sales was below the Company's historic growth rates due to
the strength of the U.S. dollar in significant foreign markets, constrained
European health care budgets, and slower than expected new product
introductions.  Health care cost containment initiatives in the U.S. have
reduced growth in demand in markets where the Company has significant market
shares, and protecting that market share has affected the Company's pricing in
some instances.

Gross profit increased 8.7% to $146.8 million in fiscal 1998 from $135.1 million
in fiscal 1997.  As a percentage of net sales, gross profit improved to 56.3% in
fiscal 1998 from 54.9% in the prior year, due primarily to a more profitable
product mix and improved manufacturing costs resulting from increased production
at the Company's international manufacturing facilities.

Research, development and engineering expenses in fiscal 1998 increased by 15.9%
to $18.4 million from $15.9 million in fiscal 1997.  As a percentage of net
sales, these expenses increased to 7.1% in fiscal 1998, compared to 6.5% in
fiscal 1997.  These expenses increased primarily as a result of development
expenses related to several clinical trials now in progress, including the
Company's Left Ventricular Assist Device ("LVAD").

Selling, general and administrative expenses increased by 9.6% to $62.9 million
during fiscal 1998 from $57.4 million in the previous year, and increased as a
percentage of net sales to 24.1% in fiscal 1998, compared to 23.4% in fiscal
1997.  The increase was due primarily to increased sales and marketing costs for
IAB products and establishing a dedicated sales force for implantable infusion
pumps.

In the fourth quarter 1998, in accordance with Statement of Financial Accounting
Standards No. 121 (FAS 121) "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of" and the Company's accounting policy
for goodwill, intangible and long-lived assets, the Company recorded a non-cash
pre-tax special charge of $36 million ($32 million after tax or $1.38 per basic
and diluted common share) to write down to fair value certain goodwill and
intangible assets.  As a result of the Company's successful development of more
advanced cardiac assist products, the Company estimated that the carrying value
of the goodwill was not recoverable.  Accordingly, the Company has reduced the
carrying value of goodwill related to previously acquired cardiac assist
products by $29 million.  The remaining carrying value of the goodwill will be
amortized using the straight-line method over 10 years.  The Company has also
reduced the carrying value of certain intangible assets related to 
                                     (15)
<PAGE>
 
FISCAL 1998 COMPARED TO FISCAL 1997 (CONTINUED):

cardiac assist technology and other assets in the amount of $7 million. The
remaining carrying value of these intangible assets will be amortized using the
straight-line method over the estimated periods of benefits, from 5 to 17 years.

Principally due to the above factors, operating income decreased 52.7% to $29.2
million in fiscal 1998 from $61.8 million in fiscal 1997.

Other expenses (income), net, decreased to $1.6 million in fiscal 1998 from $2.0
million in fiscal 1997, due to a reduction in interest expense and decreased
losses due to foreign exchange translation.  Other expenses (income), net,
consists principally of interest expense and foreign exchange gains and losses
associated with the Company's direct sales subsidiaries.  Aggregate foreign
exchange losses in fiscal 1998 and 1997 were $1.1 million and $2.0 million,
respectively, including gains relating to foreign currency contracts of $2.2 and
$2.4 million, respectively.

As a result of the factors discussed above, income before income taxes decreased
in fiscal 1998 by 53.8% to $27.6 million from $59.7 million in fiscal 1997.  The
effective income tax rate increased to 68.9% (without special charges, the
effective income tax rate decreased to 36.5%) in fiscal 1998 from 38.5% in
fiscal 1997, principally as a result of the non-deductiblity for tax purposes of
special charges related to the write down to fair value of goodwill.

Net income in fiscal 1998 decreased by 76.7% to $8.6 million from $36.7 million
in fiscal 1997.  As a percentage of net sales, net income represented 3.3% in
fiscal 1998 compared to 14.9% in the previous year.

Net income per basic and diluted common share decreased to $.37 in fiscal 1998,
a decrease of $1.21, or 76.6%, per share, from $1.58 per share in fiscal 1997
due principally to the impact of the special charges for the write down to fair
value of certain goodwill and intangible assets ($1.38 per basic and diluted
share) offset by income from operations.  Weighted average common shares
outstanding decreased to 23,224,780 in fiscal 1998 from 23,227,102 in fiscal
1997 as a result of the forfeiture of restricted stock awards by certain former
employees.

FISCAL 1997 COMPARED TO FISCAL 1996

Net sales increased by $15.9 million, or 6.9%, to $245.9 million in fiscal 1997
from $229.9 million in fiscal 1996.  Net sales represent gross sales invoiced to
customers, plus royalty income, less certain related charges, including freight
costs, discounts, returns and other allowances. This increase was due primarily
to an increase in unit shipments of central venous catheters, including
increased shipments of ARROWg+ard(TM) Blue(R) antiseptic surface treated
catheter products, pain management catheters, and implantable, constant flow
drug delivery pumps.  Sales of critical care products increased 9.6% to $207.3
million from $189.1 million in fiscal 1996.  Sales of cardiac care products
decreased 4.5% to $38.4 million from $40.3 million in the previous year, due
primarily to decrease shipments of intra-aortic balloon pump and catheter
products in Japan, where the Company is transitioning from a dealer to direct
sales.  International sales increased by $1.4 million, and represented 36.2% of
net sales, excluding royalty income, in fiscal 1997, compared to 38.2% in the
prior year, principally as a result of growth in shipments of multi-lumen
catheters, offset by the effect of the stronger U.S. dollar on sales in
significant foreign markets and by reduced shipments of intra-aortic balloon
pump and catheter products in Japan.  The percentage of net sales attributable
to the Company's direct sales force decreased in fiscal 1997 to approximately
74% from approximately 75% in fiscal 1996, principally as a result of the effect
of the stronger U.S. dollar on sales in significant foreign markets where the
Company has direct sales subsidiaries.

                                     (16)
<PAGE>
 
FISCAL 1997 COMPARED TO FISCAL 1996 (CONTINUED):

This increase in net sales was lower than the Company anticipated due to
decreased shipments of intra-aortic balloon products, the strength of the U.S.
dollar in significant foreign markets and slower than expected new product
introductions.  Health care cost containment initiatives in the U.S. have
reduced growth in demand in markets where Arrow has 80% or greater market
shares, and protecting that market share has affected the Company's pricing in
some instances.  The Company anticipates increased U.S. sales of several
products in fiscal 1998; however, U.S. demand for certain of the Company's core
products is expected to remain sluggish.  The Company also anticipates that
fiscal 1998 international sales will grow more rapidly than U.S. sales due to
rising demand in several regions of the world, supported by increased production
in the Company's Mexico and Czech Republic manufacturing facilities and the
completion of the transition from dealer to direct sales of intra-aortic balloon
products in Japan.  Continued strengthening of the U.S. dollar, however, would
adversely affect this expectation.  A return to the Company's traditionally
higher rates of sales growth is dependent on demand for its new products now in
various stages of market introduction, as well as timely receipt of required
regulatory approvals and timely completion of research and development programs.

Gross profit increased 10.1% to $135.1 million in fiscal 1997 from $122.7
million in fiscal 1996.  As a percentage of net sales, gross profit improved to
54.9% in fiscal 1997 from 53.3% in the prior year, due primarily to the
reduction in manufacturing costs resulting from increased production at the
Company's manufacturing facilities in Mexico and the Czech Republic and
increased sales of higher margin ARROWg+ard(TM) Blue(R) antiseptic surface
treated catheter products, offset by the unfavorable impact of currency
translations of foreign sales.

Research, development and engineering expenses in fiscal 1997 increased by 12.5%
to $15.9 million from $14.1 million in fiscal 1996.  As a percentage of net
sales, these expenses increased to 6.5% in fiscal 1997, compared to 6.1% in
fiscal 1996.  These expenses increased primarily as a result of development
expenses related to several new products, including the Company's Left
Ventricular Assist Device ("LVAD").

Selling, general and administrative expenses increased by 6.1% to $57.4 million
during fiscal 1997 from $54.1 million in the previous year, and decreased as a
percentage of net sales to 23.4% in fiscal 1997, compared to 23.5% in fiscal
1996.  This percentage decrease was due primarily to successful efforts to
restrain the growth in these expenditures in view of the prior year's expansion
of the Company's U.S. salesforces and Japanese and European direct sales
subsidiaries.

Principally due to the above factors, operating income increased 13.5% to $61.8
million in fiscal 1997 from $54.4 million in fiscal 1996.

Other expenses (income), net, decreased to $2.0 million in fiscal 1997 from $2.3
million in fiscal 1996, due to a reduction in interest expense, offset by
increased losses due to foreign exchange translation.  Other expenses (income),
net, consists principally of interest expense and foreign exchange gains and
losses associated with the Company's direct sales subsidiaries.  Aggregate
foreign exchange (gains) and losses in fiscal 1997 and 1996 were $2.0 million
and $0.9 million, respectively, including (gains) and losses relating to foreign
currency contracts of ($2.4) and ($1.5) million, respectively.

As a result of the factors discussed above, income before income taxes increased
in fiscal 1997 by 14.6% to $59.7 million from $52.1 million in fiscal 1996.  The
effective income tax rate increased to 38.5% in fiscal 1997 from 37.0% in fiscal
1996, principally as a result of the provision for taxes in certain state and
international jurisdictions.

Net income in fiscal 1997 increased by 11.9% to $36.7 million from $32.8 million
in fiscal 1996.  As a percentage of net sales, net income represented 14.9% in
fiscal 1997 compared to 14.3% in the previous year.

FISCAL 1997 COMPARED TO FISCAL 1996 (CONTINUED):

Net income per basic and diluted common share increased to $1.58 for fiscal
1997, an increase of $0.17, or 11.9%, per share, from $1.41 per share in fiscal
1996.  Weighted average common shares outstanding decreased to 23,227,102 in
fiscal 1997 from 23,229,687 in fiscal 1996 as a result of the forfeiture of
unvested restricted stock awards by certain former employees.

LIQUIDITY AND CAPITAL RESOURCES

For the year ended August 31, 1998, net cash provided by operations was $40.4
million, an increase of $8.0 million from the prior year.  This increase was due
primarily to an increase in net income adjusted for the impact of special
charges for the write down to fair value of certain goodwill and intangible
assets.  Accounts receivable, net of the allowance for doubtful accounts,
increased by $3.1 million for the year ended August 31, 1998, compared to a
$14.4 million increase in the prior year.  Accounts receivable, measured in days
sales outstanding, increased to 89 days at August 31, 1998, from 87 days at
August 31, 1997, due principally to an increase in the collection period for
both U.S. and international sales.  Inventories increased by $13.3 million in
the twelve months ended August 31, 1998 as compared to an increase of $13.8
million in fiscal 1997.  This was due principally to an increase in inventory to
support increased production at the Company's international manufacturing
facilities, additional inventory obtained as a result of the acquisition of
Medical Parameters, Inc. in August 1998, and an increase in inventory to support
marketing of PTD and IAB catheters.

Net cash used in the Company's investing activities increased to $38.9 million
in fiscal 1998 from $21.4 million in the prior year, principally as a result of
cash paid to acquire the Cardiac Assist Division of the Boston Scientific
Corporation and Medical Parameters Inc.

Net cash used by financing activities decreased to $3.0 million in fiscal 1998,
compared to $9.0 million in fiscal 1997.  This change resulted principally from
a decrease in the repayment of long-term debt.

As of August 31, 1998, the Company had U.S. bank credit facilities providing a
total of $50.0 million in available revolving credit for general business
purposes, of which $26.7 million remained unused.  In addition, certain of the
Company's foreign subsidiaries have revolving credit facilities totaling the
U.S. dollar equivalent of $11.3 million, of which $4.9 million remained unused
as of August 31, 1998.  Combined borrowing under these credit facilities
increased $7.8 million and decreased $5.7 million during the years ended August
31, 1998 and 1997, respectively.

During fiscal 1998, 1997 and 1996, the percentage of the Company's sales
invoiced in currencies other than the U.S. dollar was 24.7%, 26.8% and 27%,
respectively.  In addition, a small part of the Company's cost of goods sold is
denominated in foreign currencies.  As a partial hedge against these foreign
currency risk exposures, the Company periodically enters into foreign currency
exchange contracts with certain major financial institutions.  By their nature,
all such contracts involve risk, including the risk of nonperformance by
counterparties.  Accordingly, losses relating to these contracts could have a
material adverse effect upon the Company's business, financial condition and
results of operations.  Based upon the Company's knowledge of the financial
condition of the counterparties to its existing forward contracts, the Company
believes that it does not have any material exposure to any individual
counterparty.  The Company's policy prohibits the use of derivative instruments
for speculative purposes.  As of November 2, 1998, outstanding foreign currency
exchange contracts totaling the U.S. dollar equivalent of $12.7 million mature
at various dates through March 1999.  The Company expects to continue to utilize
foreign currency exchange contracts to manage its exposure, although there can
be no assurance that the Company's efforts in this regard will be successful.

Operations of the Company are also exposed to, in the normal course of business,
fluctuations in interest rates.  This interest rate risk exposure results from
changes in short-term U.S.

                                     (18)

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED):

dollar interest rates.  In an effort to manage interest rate exposure, in April
1998 the Company entered into an interest rate swap agreement to reduce
potential interest rate fluctuations on its floating rate debt.  The interest
rate swap agreement exchanges floating rate for fixed interest payments over the
5-year life of the agreement.

The Company's exposure to credit risk consists principally of trade receivables.
Hospitals and international dealers account for a substantial portion of trade
receivables and collateral is generally not required.  The Company believes that
its risk associated with this concentration is limited due to the Company's on-
going credit review procedures.

Based upon its present plans, the Company believes that its working capital,
operating cash flow and available credit sources will be adequate to repay
current portions of long-term debt, to finance currently planned capital
expenditures and to meet the currently foreseeable liquidity needs of the
Company.

During the periods discussed above, the overall effects of inflation and
seasonality on the Company's business were not significant.

YEAR 2000 READINESS

The Company has actively addressed the Year 2000 problem as it relates to its
business operations and regulation by the FDA.  This disclosure describes the
Company's progress toward its objective of ensuring that the Company's business
systems will operate satisfactorily on or after January 1, 2000.

The Company's Central Venous Catheters and other catheter products are
unaffected by the Year 2000 problem.  Early in 1998, the Company responded to
the FDA concerning the effect of the Year 2000 problem on its intra-aortic
balloon pumps.  The software in the more recent models of the pumps has taken
the change of century issues into account.  The operating range for the clock
calendar in these pumps spans a 100 year period from the years 1988 through
2087.  The clock calendar on certain older models advances as high as 1999.
However, none of the pumps depend on the year information for any calculations
or in communicating with other electronic devices, and all of these pumps will
function as intended or expected, regardless of the date.  Customers requesting
certifications are provided with specific pump model numbers that have or do not
have the updated clock calendars.

The Company's major Year 2000 concerns relate to business systems that support
the continuity of its business operations and the delivery of products and
support services to its customers.

For the Company's business applications relating to sales order processing,
billing, disbursements, marketing and manufacturing management, the necessary
software code modifications have been completed in the development version of
the applications.  During the remainder of 1998, the modified versions will be
tested by advancing dates beyond December 31, 1999.  The validated software will
then be moved to the production machines.  U.S. payroll and general ledger
software will be tested and validated in the above manner in the spring of 1999.
The cost of the Company's software upgrades is estimated to be approximately
$30,000 for all U.S. systems and $120,000 for all foreign systems.  Internal
resources devoted to these efforts are estimated at 500 man-days.  In the event
that the production systems malfunction due to the change to the Year 2000, the
software and data will be moved back to the machines on which the validation was
done so that business processes can continue.

                                     (19)

YEAR 2000 READINESS

The Company's engineering documentation systems which are critical systems for
manufacturing are planned to be tested and Year 2000 compliant by the spring of
1999.

The Company's PC systems were upgraded in fiscal 1998 at a cost of $700,000.  An
estimated $500,000 will be spent in fiscal 1999 to upgrade servers and replace
the e-mail system.

The Company's computer controlled equipment includes programmable controllers on
production equipment and systems for time and attendance recording, building
management, life safety, security, elevators, air compressors and high purity
water.  For equipment or systems controlled by computer chips or programs, the
Company plans to contact the manufacturer to determine that these systems or
equipment are Year 2000 compliant.  These efforts are expected to be completed
by the end of 1998.

The status of Year 2000 compliance by key suppliers of products and services to
the Company will be determined by using a compliance survey, which the Company
plans to mail by December 1998.  Telephone contact is planned for organizations
who do not respond or who report a lack of Year 2000 compliance in critical
business processes.

The Company increased its available domestic revolving credit facility to $75
million in October 1998. This additional borrowing capacity could be utilized to
support the Company's cash flow requirements in the event that health care
providers are unable to pay amounts owed to the Company on a timely basis due to
system malfunctions related to the Year 2000 change. 

If the Company is able to fulfill its plans to secure its business systems as
described above, then any adverse Year 2000 effects will arise from
circumstances outside the Company's control.  Because such circumstances can not
be reasonably anticipated at this time, the Company has not developed a Year
2000 worst case scenario for disclosure. While the Company believes that it is
adequately addressing the Year 2000 problem, there can be no assurance that the
costs and liabilities of the Year 2000 problem will not materially adversely
affect its business, financial condition and results of operations.

EUROPEAN UNION CONVERSION TO EURO

The Company has proactively considered issues related to conversion by eleven
member states of the European Union to a common currency, the "Euro", beginning
on January 1, 1999.  For business applications relating to sales order
processing, billing and payments the necessary software code modifications to
address the triangulation requirements of the conversion are in process.  The
cost of such modifications is approximately $50,000.  Pricing of the Company's
products in the European Union generally is market driven.  As such, the Company
is unable to determine at this time whether or not the Euro conversion will have
any impact on product pricing or contractual arrangements with health care
service providers.

RECENT DEVELOPMENT

In August 1998, the Company signed an agreement to purchase for $28 million the
global intra-aortic balloon catheter and pump business of C.R. Bard, Inc. The
acquisition is currently being reviewed pursuant to a second request for
information by the Federal Trade Commission (FTC) under the Hart Scott-Rodino
Antitrust Improvements Act of 1976. Sales of C.R. Bard's intra-aortic balloon
products were approximately $14 million in 1998.

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED:

On March 4, 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position (SOP) 98-1 "Accounting for the Costs of Computer
Software Development or Obtained for Internal Use".  The SOP provided guidance
on accounting for the costs of computer software developed or obtained for
internal use.  The SOP is effective for financial

                                     (20)

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED (CONTINUED):

statements for fiscal years beginning after December 15, 1998, but earlier
application is encouraged.  The Company does not anticipate the adoption of this
new standard to have a material effect on the Company's consolidated financial
statements.  The Company will adopt this standard in fiscal year 1999.

In June 1997, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS
130).  FAS 130 establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
The statement is effective for financial statements for fiscal years beginning
after December 15, 1997.  The Company does not anticipate the adoption of this
new standard to have a material effect on the Company's consolidated financial
statements.

In June 1997, the FASB issued FAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information".  This statement requires that a public
business enterprise report financial and descriptive information about its
reportable operating segments.  The statement is effective for fiscal years
beginning after December 15, 1997.  The Company need not currently adopt the
standard as the Company maintains separate financial information available for
regular evaluation by the chief operating decision maker for only one segment.

During February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pension and Other Postretirement Benefits" (FAS 132).  FAS 132 does not
change the measurement or recognition of those plans.  It standardizes the
disclosure requirements for pensions and other postretirement benefits, requires
additional information on changes in the benefit obligations and fair values of
plan assets, and eliminates certain disclosures that are no longer as useful.
The statement is effective for fiscal years beginning after December 15, 1997,
but earlier application is encouraged.  The adoption of SFAS No. 132 is not
expected to have any impact on the Company's results of operations, financial
position or cash flows.

On June 15, 1998, the FASB issued FAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (FAS 133).  FAS 133 establishes new
procedures for accounting for derivatives and hedging activities and supersedes
and amends a number of existing standards.  FAS 133 is effective for fiscal
years beginning after June 15, 1999, but earlier application is permitted as of
the beginning of any fiscal quarter subsequent to June 15, 1998.  The adoption
of this new standard will not have a material effect on the Company as FAS 133
retains the provisions of Statement of Accounting Standards No. 52 "Foreign
Currency Translation" with respect to long-term and short-term intercompany
transactions eliminating the need for special accounting and does not change the
accounting for interest rate swaps.

To the Shareholders and the Board of Directors of Arrow International, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, shareholders' equity and cash flows present
fairly, in all material respects, the financial position of Arrow International,
Inc. ("the Company") at August 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
August 31, 1998, in conformity with generally accepted accounting principles.
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 of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation.  We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     (All Dollar Amounts in Thousands, Except Share and Per Share Amounts)

1.  Summary of Significant Accounting Policies:

General:

Arrow International, Inc. develops, manufactures and markets a broad range of
clinically advanced, disposable catheters and related products for critical care
and interventional medical procedures.

Principles of Consolidation:

The accompanying consolidated financial statements include the accounts of Arrow
International, Inc. and its wholly-owned subsidiaries (collectively, the
"Company"). All significant intercompany transactions have been eliminated in
consolidation. Certain prior period amounts have been reclassified to conform to
the fiscal 1998 presentation.

Cash and Cash Equivalents:

The Company considers all highly liquid debt instruments purchased with a
maturity of 90 days or less to be cash equivalents. The Company's cash
management program utilizes zero balance accounts. The carrying amount of cash
and cash equivalents approximate fair value.

Use of Estimates:

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, disclosure of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

Inventory Valuation:

Inventories are valued at lower of cost or market. Cost is determined by the
"first-in, first-out" (FIFO) method.

Goodwill, Intangible and Other Assets:

Goodwill represents the excess of the cost over the fair value of net assets
acquired in business combinations. Goodwill is amortized using the straight-line
method over a period of 15 to 25 years depending on the circumstances.
"Intangible and Other Assets, net" include certain assets acquired from business
acquisitions and investments and are being amortized using the straight-line
method over their estimated periods of benefits, from 5-17 years. Management
reviews the carrying amount of goodwill, intangible and other assets at each
balance sheet date to assess the continued recoverability based on future gross
cash flows and operating results from the related asset, future asset
utilization and changes in market conditions. In accordance with Statement of
Financial Accounting Standards No. 121 (FAS 121) "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed of", long-lived
assets and certain identifiable intangibles to be held and used or disposed of
are reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. If an evaluation is
required and a market value is not determinable, the estimated future
undiscounted cash flows associated with the asset would be compared to the
asset's carrying amount to determine if a write down to a new basis is required.
Impairment will be recorded based on an estimate of future discounted cash
flows.

1.  Summary of Significant Accounting Policies (Continued):

Property, Plant and Equipment:

Property, plant and equipment are stated at cost and are depreciated over the
estimated useful lives of the assets using the straight-line method ranging from
3 to 31 years. Upon retirement, sale or other disposition, the cost and
accumulated depreciation are eliminated from the accounts and any gain or loss
is included in operations.

Capitalized Interest:

Interest is capitalized as part of the historical cost of certain property,
plant and equipment constructed by the Company for its own use. The amount of
interest capitalized is based on a weighted average of the interest rates of
outstanding borrowings during the construction period.

Marketable Equity Securities:

Marketable securities are carried at fair market value, with unrealized holding
gains and losses, net of tax, reported as a separate component of shareholders'
equity. The fair market value of securities held at August 31, 1998 and 1997 was
$4,352 and $6,374 and the unrealized holding loss was $3,375 and $2,158,
respectively.

Financial Instruments:

The Company enters into foreign currency exchange forward contracts, which are
derivative financial instruments, with certain major financial institutions to
reduce the effect of fluctuating exchange rates, primarily on U.S. dollar cash
inflows resulting from the collection of intercompany receivables denominated in
foreign currencies. In 1997, the Company classified a portion of certain
Intercompany receivables as long-term investments. The foreign exchange
translation effect related to the investment is included in the cumulative
translation adjustment section of shareholders' equity. Such transactions occur
throughout the year and are probable, but not firmly committed. Forward
contracts are marked to market each accounting period, and the resulting gains
or losses on these contracts are recorded in Other Income / Expense of the
consolidated statements of income. Realized gains and losses on these contracts
are offset by the assets, liabilities and transactions being hedged. In 1998,
the Company entered into an interest rate swap agreement to reduce the impact of
its floating rate debt. The interest rate swap agreement allows the Company to
exchange floating rate for fixed interest payments over the life of the
agreement. The differential is accrued as interest rates change and is recorded
as interest expense. The Company does not use financial instruments for trading
or speculative purposes.

Revenue Recognition:

Revenue is recognized at the time products are shipped and title has passed to
the customer. Net sales represent gross sales invoiced to customers, plus
royalty income, less certain related charges, including freight costs,
discounts, returns and other allowances.

Income Taxes:

The Company recognizes deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns using current tax rates. Undistributed earnings of the
Company's foreign subsidiaries are indefinitely reinvested and amounted to
$8,193 and $7,268 at August 31, 1998 and 1997, respectively. No deferred taxes
have been provided on these earnings.

1.  Summary of Significant Accounting Policies (Continued):

Foreign Currency Translation:

During fiscal 1998 and 1997 most of the Company's foreign subsidiaries used
their local currency as the functional currency and translated all assets and
liabilities at year-end exchange rates, all income and expense accounts at
average rates and recorded adjustments from the translation in a separate
component of shareholders' equity. The foreign subsidiaries that still used the
U.S. dollar as the functional currency translated monetary assets and
liabilities at year-end exchange rates and inventories, property and nonmonetary
assets and liabilities at historical rates. Income and expense accounts were
translated at the average rates in effect during the year, except that
depreciation, amortization and cost of sales were translated at historical
rates. Adjustments resulting from the translation of the entities were included
in "Other expenses (income)" of the consolidated statements of income. Gains and
losses resulting from transactions of the Company and its foreign subsidiaries
were included in "Other expenses (income)". Aggregate foreign exchange losses
were $1,102, $1,996 and $919 for the years ended August 31, 1998, 1997 and 1996,
respectively.

Concentration of Credit Risk:

Concentration of credit risk with respect to trade receivables is limited due to
both the large number of customers and their geographic dispersion. As of August
31, 1998 and 1997, the Company had no significant concentrations of credit risk.

Postretirement Benefits Other Than Pensions:

Postretirement health care and life insurance benefits are recorded using the
accrual method of accounting based on actuarially determined costs, which are
recognized over the period from the date of hire to the full eligibility date of
employees who are expected to qualify for such benefits.

Earnings/(Loss) Per Share

Basic earnings/(loss) per common share is computed by dividing net income/(loss)
available to common shareholders by the weighted-average number of common shares
outstanding during the period. Diluted earnings/(loss) per share is computed by
dividing net income/(loss) available to common shareholders by the weighted-
average number of shares that would have been outstanding if the dilutive
potential common shares had been issued. The diluted earnings/(loss) per share
does not assume the exercise of options that would have an antidilutive effect
on earnings/(loss) per share.

Cost of Start-up Activities:

In the fourth quarter 1998, the Company adopted Statement of Position (SOP) 98-5
"Reporting the Costs of Start-up Activities" issued by the Accounting Standards
Executive Committee of the Institute of Certified Public Accountants (AcSec). It
requires costs of start-up activities and organization costs to be expensed as
incurred. As a result of the adoption, the Company recorded additional expense
included in "Special Charges" of $580 ($368 after tax) or $.016 per basic and
diluted common share.

2.   Special Charges:

In the fourth quarter 1998, and in accordance with Statement of Financial
Accounting Standards No. 121 (FAS 121) "Accounting for the Impairment of Long-
Lived Assets and Long-Lived Assets to be Disposed of" and the Company's
accounting policy for goodwill, intangible and other assets, the Company
recorded a non-cash pre-tax special charge of $36 million ($32 million after tax
or $1.38 basic and diluted per share) to write down to fair value certain
goodwill and intangible assets. As a result of the Company's successful
development of more advanced cardiac assist products, the Company estimated that
the carrying value of the goodwill was not recoverable. Accordingly, the Company
has reduced the carrying value of goodwill related to previously acquired
cardiac assist products by $29 million. The remaining carrying value of these
intangible assets will be amortized using the straight-line method over the
estimated periods of benefits, from 5 to 17 years.

3.   Business Acquisitions:

On July 15, 1997, the Company expanded its critical care product line by
acquiring the implantable constant flow drug delivery pump product business of
Strato/Infusaid Inc., a former subsidiary of Pfizer, Inc. The acquisition has
been accounted for using the purchase method of accounting. In conjunction with
the acquisition, the Company discontinued manufacturing operations effective on
or about November 30, 1997, and compensation expense of $3,464 was accrued and
paid for employee terminations. The cost of the acquisition has been allocated
on the basis of the estimated fair market value of the assets acquired, $6,051
and the liabilities assumed, $4,049. The results of operations are included in
the Consolidated Statements of Income from the date of acquisition.

On November 5, 1997, the Company continued its expansion into the cardiac care
market by purchasing the assets of the Cardiac Assist Division of the Boston
Scientific Corporation, a manufacturer and marketer of intra-aortic balloon
catheters and an intra-aortic balloon pump, for $7.3 million. The acquisition
has been accounted for using the purchase method of accounting. The results of
operations are included in the Consolidated Statements of Income from the date
of acquisition. The excess of the purchase price over the estimated fair value
of net assets acquired of approximately $5.5 million is being amortized over a
period of 15 years.

On August 3, 1998, the Company acquired Medical Parameters, Inc. (MPI), a maker
of custom manufactured tubing sets used by critical care physicians to connect
central venous catheters to blood pressure monitoring devices and drug infusion
systems for $15 million in cash. The acquisition has been accounted for using
the purchase method of accounting. The results of operations are included in the
Consolidated Statements of Income from the date of acquisition. The excess of
the purchase price over the estimated fair value of the net assets acquired of
approximately $12.2 million is being amortized over a period of 25 years.

Pro forma amounts are not presented as the aforementioned acquisitions had no
material effect on the Company's results of operations or financial condition
for any of the years presented.

4.   Stock Option Plans:

The Company has adopted two stock plans, the 1992 Stock Incentive Plan (the
"1992 Plan"), which was adopted on April 1, 1992, and the Directors Stock
Incentive Plan (the "Directors Plan"), which was approved by the shareholders on
January 17, 1996. The 1992 Plan authorizes the granting of stock options, stock
appreciation rights and restricted stock. The Directors Plan authorizes the
granting of a maximum of 100,000 non-qualified stock options. Under the
Directors Plan, members of the Board of Directors of the Company and its
subsidiaries are eligible to participate if they are not also employees or
consultants of the Company or its subsidiaries, were not shareholders at the
time of the Company's initial public offering on June 9, 1992 and do not serve
on the Board as representatives of the interest of shareholders who have made an
investment in the Company. The Directors Plan authorizes an initial grant of an
option to purchase 5,000 shares of common stock upon each eligible director's
initial election to the Board and the grant of an additional option to purchase
500 shares of common stock on the date each year when directors are elected to
the Board.

The Company follows the provision of Accounting Principles Board (APB) No. 25,
"Accounting for Stock Issued to Employees", and related interpretations, which
require compensation expense for options to be recognized only if the market
price of the underlying stock exceeds the exercise price on the date of grant.
Accordingly, the Company has not recognized compensation expense for its options
granted during the 1998, 1997 and 1996 fiscal years.

On December 1, 1993 and February 11, 1994, the Company issued 44,900 and 8,200
shares, respectively, of restricted common stock to certain employees pursuant
to the 1992 Plan. The market value of the shares awarded, based on the closing
price of $20.75 and $23.125 per share, as reported by the Nasdaq stock market on
the dates of the awards, was $932 and $190, respectively. The transactions were
recorded as unearned compensation in a separate component of shareholders'
equity and are being amortized to expense over the five year vesting period.

In fiscal years 1998 and 1996, options to purchase 180,900 and 171,700 shares,
respectively of the Company common stock were granted to key employees of the
Company pursuant to the 1992 plan. There were no options granted in the fiscal
year 1997. The option price per share ranged from $27.75 to $35 in fiscal year
1998 and was $38 in fiscal year 1996. These amounts represent the fair market
value of the common stock of the Company on the dates the options were granted.
The options expire ten years from the grant date. The options vest ratably over
five years at one year intervals from the grant date and become exercisable at
any time once vested.

On January 21, 1998, January 15, 1997 and January 17, 1996, options to purchase
6,500, 10,500 and 5,000 shares, respectively, of the Company common stock were
granted to directors of the Company pursuant to the Directors Plan. The option
price per share for the 1998, 1997 and 1996 awards were $38.375, $29.25 and $38,
respectively, the fair market value of the common stock of the Company on the
dates the options were granted. The options expire ten years from the grant
date. The options vest fully one year from the grant date and become exercisable
at any time once vested.

The Company adopted the disclosure provisions of FAS No. 123, "Accounting for
Stock-Based Compensation".  As permitted under FAS 123, the Company continues to
apply the existing accounting rules under APB No. 25 and provide pro forma net
income and pro forma earnings per share disclosures for employee stock option
grants made as if the fair value method in measuring compensation cost for stock
options granted subsequent to December 15, 1995, had been applied.

The per share weighted average value of stock options granted in 1998,1997 and
1996 was $13.35, $13.88 and $15.50, respectively.  The fair value was estimated
as of the grant date using the Black-Scholes option pricing model with the

5.  Related Party Transactions:

During the year ended August 31, 1998, the Company assumed certain pension and
retirement health care benefit obligations of Arrow Precision Products, Inc.
("Precision"), which is related to the Company through common ownership, to
former employees of Precision who are currently, or previously were, employed by
the Company in exchange for the transfer by Precision to the Company of
appropriate assets to satisfy such obligations.  See Note 12. Retirement
Benefits for additional details related to this transaction.  In addition,
Precision transferred to the Company, with no payment by either party to the
other, its rights and responsibilities under a split dollar life insurance
policy covering the former Chief Operating Officer of Precision.

The Company also made payments on behalf of Precision in the amount of $170,
relating to activities of Precision prior to August 29, 1997, for which
reimbursement was offset by credits of $37 issued by the Company to Precision
against previous charges for utilization of certain of the Company's facilities,
personnel and services during the twelve month period ended August 29, 1997.
The Company made no purchases from Precision during the year ended August 31,
1998.  The Company had a net receivable from Precision amounting to $369 at
August 31, 1998.

During fiscal 1997, certain of the Company facilities, personnel and services
were utilized by Precision.  Effective August 29, 1997, such utilization ended
when Precision Medical Products, Inc., the wholly owned and remaining operating
subsidiary of Precision, was acquired by a company formed by certain management
employees of Precision.

providing a total of $50,000, in revolving credit for general business purposes
of which $23,322 and $18,902 were outstanding, respectively.  Interest rate

5.7%, respectively.  At August 31, 1998 and 1997, certain of the Company's
foreign subsidiaries had available revolving credit facilities, at market rates
of interest, totaling the U.S. dollar equivalent of $11,323 and $11,791, under

to maintain a ratio of total liabilities to tangible net worth (total assets
less total liabilities and intangible assets) of no more than 1.5 to 1 and a

12.  Retirement Benefits:

Pension Plans:

The Company has three noncontributory pension plans that cover substantially all
employees.  Benefits under the plans are based upon an employee's compensation
and years of service and, where applicable, the provisions of negotiated labor
contracts.  It is the Company's policy to make contributions to these plans
sufficient to meet the minimum funding requirements of applicable laws and
regulations plus such additional amounts, if any, as the Company's actuarial
consultants advise to be appropriate.  The projected unit credit method is
utilized for determination of actuarial amounts.

As discussed in Note 5 Related Party Transactions, the Company assumed certain
pension obligations of Arrow Precision Products, Inc. ("Precision"), which is
related to the Company through common ownership, to former employees of
Precision who are currently or previously were, employed by the Company in
exchange for the transfer by Precision to the Company of appropriate assets to
satisfy such obligations.  Consequently, Precision's two pension plans, both of
which were overfunded as of August 31, 1997, were merged with the Company's
pension plans covering comparable employees.  The Company paid Precision $2,975,
the amount by which the value of Precision's pension plan assets exceeded the
actuarially determined present value of Precision's pension plan obligations.
The payment exceeded the prepaid pension asset recorded on Precision's financial
statements by $2,071.  This difference ("Plan acquisition differential") is
being amortized over an actuarially determined period.

12.  Retirement Benefits (Continued):

Plan assets consist principally of U.S. government securities, short-term
investments, other equity securities and cash equivalents.

Postretirement Benefits Other Than Pensions:

The Company provides limited amounts of postretirement health and life insurance
benefit plan coverage for substantially all of its employees.  The determination
of postretirement benefit cost for postretirement health benefit plans is based
on comprehensive hospital, medical, surgical, and dental benefit provisions.
The determination of postretirement benefit cost for postretirement life
insurance benefits is based on stated policy amounts.

As discussed in Note 5 Related Party Transactions, the Company assumed certain
postretirement benefit obligations of Arrow Precision Products, Inc.
("Precision"), which is related to the Company through common ownership, to
former employees of Precision who are currently or previously were, employed by
the Company in exchange for the transfer by Precision to the Company of
appropriate assets to satisfy such obligations.  Consequently, Precision's
postretirement benefit plan, which was unfunded as of August 31, 1997, was
merged with the Company's postretirement plan covering comparable employees.
Precision paid the Company $757, the actuarially determined present value of
Precision's postretirement benefit plan obligations.  The payment exceeded the
post retirement benefit liability recorded on Precision's financial statements
by $607.  This difference, ("Plan acquisition differential") is being amortized
over an actuarially determined period.

For the years ended August 31, 1998, 1997 and 1996, respectively, the components
of periodic expense for the postretirement benefits are as follows:

On cost components                                    $  73   $  99   $   92
On accumulated benefit obligation                     $ 583   $ 689   $  654
</TABLE>

It is anticipated that the health care cost trend rate will decrease gradually
from 7.00% in 1999 to 5.00% in the year 2009.

Savings Plan:

The Company has a defined contribution savings plan that covers substantially
all of its eligible U.S. employees.  The purpose of the plan is generally to
provide additional financial security to employees during retirement.
Participants in the savings plan may elect to contribute, on a before-tax basis,
a certain percent of their annual earnings with the Company matching a portion
of these contributions.  Expense under the plan was $838, $789 and $737 for the
fiscal years ended August 31, 1998, 1997 and 1996, respectively.

14.  Financial Instruments:

During fiscal 1998 and 1997, the percentage of the Company's sales invoiced in
currencies other than U.S. dollars was 24.7% and 26.8%, respectively.  In
addition, a small part of the Company's cost of goods sold is denominated in
foreign currencies.  The Company enters into foreign currency forward contracts,
which are derivative financial instruments, with major financial institutions to
reduce the effect of these foreign currency risk exposures, primarily on U.S.
dollar cash inflows resulting from the collection of intercompany receivables
denominated in foreign currencies.  Such transactions occur throughout the year
and are probable, but not firmly committed.  Forward contracts are marked to
market each accounting period, and the resulting gains or losses on these
contracts are recorded in Other Income / Expense of the consolidated statements
of income.  Realized gains and losses on these contracts are offset by the
assets, liabilities and transactions being hedged.  The Company does not use
financial instruments for trading or speculative purposes.  The Company expects
to continue to utilize foreign currency exchange contracts to manage its
exposure, although there can be no assurance that the Company's efforts in this
regard will be successful.

Operations of the Company are also exposed to, in the normal course of business,
fluctuations in interest rates.  This interest rate risk exposure results from
changes in short-term U.S. dollar interest rates.  In an effort to manage
interest rate exposure. In April 1998 the Company entered into an interest rate
swap agreement to reduce the impact of its floating rate debt. The swap
agreement exchanges floating rates for fixed interest payments over the life of
the agreement.

The Company's exposure to credit risk consists principally of trade receivables.
Hospitals and international dealers account for a substantial portion of trade
receivables and collateral is generally not required.  The risk associated with
this concentration is limited due to the Company's on-going credit review
procedures.

At August 31, 1998, the Company had forward exchange contracts to sell foreign
currencies which mature at various dates through March 1999. The following table
identifies forward exchange contracts to sell foreign currencies and interest
rate swap agreement at August 31, 1998 and 1997 as follows:

14.  Financial Instruments (Continued):

In 1998, the Company entered into an interest rate swap to reduce the impact of
its floating rate debt.  The swap agreement allows the Company to exchange
floating rates for fixed interest payments over the life of the agreement.  The
differential is accrued as interest rates change and is recorded as interest
expense.  The agreement expires in May 2003, but allows for early termination.
The effect of the agreement is to limit interest rate exposure to 5.62% on $5.0
million of its revolving credit.  As a result of the swap agreement interest
expense was increased by $2.0.

15.  Contingencies:

The Company is a party to certain legal actions arising in the ordinary course
of its business.  Based upon information presently available, the Company
believes it has adequate legal defenses or insurance coverage for these actions
and that the ultimate outcome of these actions would not have a material effect
on the Company's financial position or results of operations.

16.  Statements of Financial Accounting Standards not yet Adopted:

On March 4, 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position (SOP) 98-1 "Accounting for the Costs of Computer
Software Development or Obtained for Internal Use".  The SOP provided guidance
on accounting for the costs of computer software developed or obtained for
internal use.  The SOP is effective for financial statements for fiscal years
beginning after December 15, 1998, but earlier application is encouraged.  The
Company does not anticipate the adoption of this new standard to have a material
effect on the Company's consolidated financial statements.  The Company will
adopt this standard in fiscal year 1999.

In June 1997, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS
130).  FAS 130 establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
The statement is effective for financial statements for fiscal years beginning
after December 15, 1997.  The Company does not anticipate the adoption of this
new standard to have a material effect on the Company's consolidated financial
statements.

In June 1997, the FASB issued FAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information".  This statement requires that a public
business enterprise report financial and descriptive information about its
reportable operating segments.  The statement is effective for fiscal years
beginning after December 15, 1997.  The Company need not currently adopt the
standard as the Company maintains separate financial information available for
regular evaluation by the chief operating decision maker for only one segment.

During February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pension and Other Postretirement Benefits" (FAS 132).  FAS 132 does not
change the measurement or recognition of those plans.  It standardizes the
disclosure requirements for pensions and other postretirement benefits, requires
additional information on changes in the benefit obligations and fair values of
plan assets, and eliminates certain disclosures that are no longer as useful.
The statement is effective for fiscal years beginning after December 15, 1997,
but earlier application is encouraged.  The adoption of SFAS No. 132 is not
expected to have any impact on the Company's results of operations, financial
position or cash flows.

On June 15, 1998, the FASB issued FAS No. 133, "Accounting for Derivative

16.  Statements of Financial Accounting Standards not yet Adopted (Continued):

Hedging Activities" (FAS 133).  FAS 133 establishes new procedures for
accounting for derivatives and hedging activities and supersedes and amends a
number of existing standards.  FAS 133 is effective for fiscal years beginning
after June 15, 1999, but earlier application is permitted as of the beginning of
any fiscal quarter subsequent to June 15, 1998.  The adoption of this new
standard will not have a material effect on the Company as FAS 133 retains the
provisions of Statement of Accounting Standards No. 52 "Foreign Currency
Translation" with respect to long-term and short-term intercompany transactions
eliminating the need for special accounting and does not change the accounting
for interest rate swaps.

18.  Subsequent Events

In August 1998, the Company signed an agreement to purchase for $28 million the
global intra-aortic balloon catheter and pump business of C.R. Bard, Inc. The
acquisition is currently being reviewed pursuant to a second request for
information by the Federal Trade Commission (FTC) under the Hart Scott-Rodino
Antitrust Improvements Act of 1976. Sales of C.R. Bard's intra-aortic balloon
products were approximately $14 million in 1998.

19.  Earnings per Share:

In the second quarter of 1998, the Company adopted Statement of Accounting
Standards No. 128, "Earnings per Share", which requires presentation in the
Consolidated Statement of Income of both basic and diluted earnings per share.
The Company restated all prior years' per

share amounts presented in these Consolidated Financial Statements and notes
according to FAS 128.  Earnings per common share (basic) as calculated in
accordance with this Statement does not differ from earnings per share reported
in prior periods and earnings (loss) per common share assuming dilution is not
materially different.

The net income effect of dilutive securities was not significant.  A
reconciliation of weighted average common shares outstanding to weighted average
common shares outstanding assuming dilution follows:

(1)  Issuable primarily under stock option plans.

Stock options outstanding at August 31, 1998 to purchase 335,760 shares of
common stock were not included in the computation of earnings per common share
assuming dilution because the options' exercise prices were greater than the
average market price of the common shares.

In 1997 and 1996, the weighted average number of shares outstanding for the
basic and diluted per share calculations are identical since the assumed
exercise of outstanding options would be antidilutive.

direct consequence of (i) any breach of any representation or warranty of
Sellers contained in this Agreement which by the terms of Section 8.4 survives
the Closing, (ii) any breach of any covenant of Sellers contained in this
Agreement; provided, however, that the covenants of A. Walter


                                       44
<PAGE>
 
MacEachern and Michael A. Russell, two of the Sellers, set forth in Section 5.1
(f) are several and not joint and several, and any breach by either individual

(iii) the release or threatened release of any Hazardous Substance by the
Company or its employees or agents during the Company's ownership, lease or
operation of real property now or formerly owned, leased or operated by the
Company (or with respect to the Facility, during or prior to the Company's lease
of the Facility) to the extent arising prior to the Closing Date at, on, or

clause (ii) above) unless and until the aggregate of all Losses, for which
Sellers would, but for this proviso, be liable exceeds on a cumulative basis a
dollar amount equal to One Hundred Thousand Dollars ($100,000.00) (the
"Basket"), and then only to the extent of any amount which, in the aggregate,
exceeds the Basket; provided, further, that Sellers shall not have any liability
hereunder unless and until the amount of Loss with respect to each individual
matter, or series of related matters, exceeds Ten Thousand Dollars ($10,000.00)

Sellers to Buyer (including, but not limited to, liabilities of

                                       45
<PAGE>

therewith or in connection with the curing of any or all breaches of the
Sellers' representations and warranties) collectively pursuant to this Section
7.l(a) shall not exceed Three Million Dollars ($3,000,000.00) (the "Cap");
provided, however that the Cap shall not apply to any obligation arising out of
the Tax indemnification provided for in Section 6.3(e) of this Agreement; nor
shall any such Tax obligation be included in determining or calculating the Cap.

         (b) Buyer acknowledges and agrees that Sellers shall not have any
liability under any provision of this Agreement for any Loss to the extent that
such Loss relates to actions taken by or omitted to be taken by Buyer, the
Company or their respective Affiliates after the Closing Date.

Company, hereby agrees to indemnify Sellers against and hold them harmless on a
net after-Tax basis from any loss suffered or incurred by Sellers (other than
any relating to Taxes, for which indemnification provisions are set forth in
Section 6.3 of this Agreement) as a direct consequence of (i) any breach of any
representation or warranty of the Buyer contained in this Agreement which by the
terms of Section 8.4 survives the Closing, (ii) any breach of any covenant of
Buyer contained in this Agreement, (iii) any obligation or liability of the
Company arising on or after the Closing Date (except to the extent Sellers are
obligated to indemnify Buyer pursuant to Section 7.1(a) of this Agreement), or

7.2, the release or threatened release, or the exacerbation of any pre-Closing
release (but only to the extent of such exacerbation), of any Hazardous
Substance, to the extent arising after the Closing Date at, on, or under any
portion of the real property owned, leased or operated by the Company
(including, without limitation, the

                                       46
<PAGE>
 
Facility) which requires remediation under applicable Environmental Laws or
which constitutes a violation of applicable Environmental Laws or the off-site
disposal or shipment for disposal by the Company on or after the Closing Date of
any Hazardous Substance; provided, however, that Buyer shall not have any
liability hereunder unless and until the aggregate of all Losses, for which
Buyer would, but for this proviso, be liable exceeds on a cumulative basis the
Basket, and then only to the extent of any amount which, in the aggregate,
exceeds the Basket; provided, further, that Buyer shall not have any liability
hereunder unless and until the amount of Loss with respect to each individual
matter, or series of related matters, exceeds the Sub-limit; provided, further,
that the maximum aggregate obligation of Buyer to the Sellers (including, but
not limited to, liabilities of the Buyer for costs, expenses and attorneys' fees
paid or incurred in connection therewith or in connection with the curing of any
or all breaches of Buyer's representations or warranties) collectively pursuant
to this Section 7.2(a) shall not exceed the Cap.

     7.3 Losses Net of Insurance, Etc.  The amount of any Loss for which
         ----------------------------                                   
indemnification is provided under this Article VII shall be net of (i) in the
case of Section 7.1, any accruals or reserves on the Annual Financial Statements
which relate specifically to such Loss, (ii) any amounts recovered by the
Indemnified Party (as such term is defined in Section 7.5 of this Agreement)
pursuant to any indemnification by or indemnification agreement with any third
party, (iii) the positive difference, if any, between (a) any insurance proceeds
or other cash receipts or sources of reimbursement recovered as an offset
against such Loss and (b) the net present value of any increase in insurance
premiums payable by the Indemnified Party which such party is able to
demonstrate to the Indemnifying Party (as such term is defined in Section 7.5 of
this Agreement) is directly attributable



                                       47
<PAGE>
 
to any insurance proceeds paid on account of such Loss (each such Person named
in clauses (i), (ii) and (iii), a "Collateral Source") and (iv) an amount equal
to the Tax benefit, if any, attributable to such Loss.  If the amount to be
netted hereunder from any payment required under Sections 7.1 or 7.2 is
determined after payment by the Indemnifying Party of any amount otherwise
required to be paid to an Indemnified Party pursuant to this Article VII, the
Indemnified Party shall repay to the Indemnifying Party, promptly after such
determination, any amount that the Indemnifying Party would not have had to pay
pursuant to this Article VII had such determination been made at the time of
such payment.

     7.4 Termination of Indemnification.  The obligations to indemnify and hold
         ------------------------------

the applicable representation or warranty terminates pursuant to Section 8.4;
provided; however, that the obligation of Sellers to indemnify and hold harmless
Buyer pursuant to Section 7.1(a) clause (iii) with respect to the Facility shall
terminate on the third anniversary of the Closing Date; provided, further, that
the obligation of Sellers to indemnify and hold harmless Buyer pursuant to
Section 7.1(a) clause (iii) with respect to the off-site disposal or shipment
for disposal by the Company prior to the Closing Date of any Hazardous Substance
and pursuant to Section 7.1(a) clause (iv) with respect to injury or death
resulting from a release or threatened release of any Hazardous Substance shall
terminate on the fifth (5th) anniversary of the Closing Date; provided, further,
that such obligations to indemnify and hold harmless shall not terminate with
respect to any item as to which the person to be indemnified (or the related
party thereto) shall have, before the expiration of the applicable period,
previously made a claim by delivering a notice (stating in reasonable detail the
basis of such claim) to the party providing


                                       48
<PAGE>
 
the indemnification.  Notwithstanding the aforesaid, the obligations of all of
the Sellers, other than A. Walter MacEachern and Michael A. Russell, to

and the Company to indemnify and hold harmless the Sellers, pursuant to Section
7.2(a)(iv) with respect to the Facility, shall terminate on the third (3rd)
anniversary of the Closing Date, and the obligations of the Buyer and the
Company to indemnify and hold harmless the Sellers, pursuant to Section 7.2 (iv)
with respect to off-site disposal, or shipment for disposal, by the Company on
or after the Closing Date of any Hazardous Substances shall terminate on the
fifth (5th) anniversary of the Closing Date.

     7.5 Procedures Relating to Indemnification under Sections 7.1 and 7.2 In
         -----------------------------------------------------------------   
order for a party (the "Indemnified Party") to be entitled to any
indemnification provided for under Sections 7.1 or 7.2 of this Agreement in
respect of, arising out of or involving a claim or demand made by any Person
against the Indemnified Party (a "Third Party Claim"), such Indemnified Party
must notify the party from whom indemnification is sought (the "Indemnifying
Party") in writing of the Third Party Claim within ten (10) Business Days after
receipt by such Indemnified Party of written notice of the Third Party Claim;
provided, however, that failure to give such notification shall not affect the
indemnification provided hereunder except to the extent the Indemnifying Party
shall have been prejudiced as a result of such failure (except that the
Indemnifying Party shall not be liable for any expenses incurred during the
period in which the Indemnified Party failed to give such notice).

                                       49
<PAGE>
 
Thereafter, the Indemnified Party shall deliver to the Indemnifying Party,
within five (5) Business Days after the Indemnified Party's receipt thereof,
copies of all notices and documents (including, without Stations court papers)
received by the Indemnified Party relating to the Third Party Claim.

     If a Third Party Claim is made against an Indemnified Party, the
Indemnifying Party will be entitled to participate in the defense thereof and,
if it so chooses, assume at any time the defense thereof with counsel selected
by the Indemnifying Party and reasonably acceptable to the Indemnified Party.
Should the Indemnified Party so elect to assume and control the defense and
settlement of a Third Party Claim (assuming the Indemnifying Party has not
chosen to assume such defense), the Indemnifying Party will not be liable to the
Indemnified Party for legal expenses subsequently incurred by the Indemnified
Party in connection with the defense or settlement thereof.  If the Indemnifying
Party assumes such defense, the Indemnified Party shall have the right to
participate in, but not control, the defense thereof and to employ counsel, at
its own expense, separate from the counsel employed by the Indemnifying Party.
The Indemnifying Party shall be liable for the fees and expenses of counsel
employed by the Indemnified Party for any period during which the Indemnifying
Party has not assumed the defense thereof (subject to the first sentence of the
first paragraph of this Section 7.5). Whether or not the Indemnifying Party
chooses to defend or prosecute any Third Party Claim, both parties hereto shall
cooperate in the defense or prosecution thereof.  Such cooperation shall include
the retention and (upon the Indemnifying Party's written request) the provision
to the Indemnifying Party of records and information which are reasonably
relevant to such Third Party Claim, and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder.  Whether or not the Indemnifying


                                       50
<PAGE>
 
Party shall have assumed the defense of a Third Party Claim, the Indemnifying
Party shall not admit any liability with respect to, or settle, compromise or
discharge, such Third Party Claim without the Indemnified Party's prior written
consent.

     7.6 Exclusive Remedy.  The indemnification provided in this Article II
         ----------------                                                  
shall be the sole and exclusive remedy after the Closing Date for monetary
damages available to Buyer and Sellers for breach of any of the terms,
conditions, representations or warranties contained herein.  As between Sellers
on the one hand, and Buyer and its Affiliates, including without limitation
after the Closing, the Company, on the other hand, the rights and obligations
set forth in this Agreement will be the exclusive rights and obligations with
respect to this Agreement, the events giving rise to this Agreement and the
transactions provided for herein or contemplated hereby.  Without limiting the
generality or effect of the foregoing, as a material inducement to the other
parties hereto entering into this Agreement, and in right of, among other
factors, the acknowledgments contained in this Section 7.6, each of the parties
to this Agreement hereby waives any claim or cause of action, known and unknown,
foreseen and unforeseen, which exists or may arise in the future, or which it
otherwise might assert, including without limitation under the common law or
Federal or state securities laws, trade regulation laws, Environmental Laws
(including CERCLA or any other statutes now or hereafter in effect) or other
laws, by reason of this Agreement, the events giving rise to this Agreement and
the transactions provided for herein or contemplated hereby or thereby, except
for (i) claims or causes of action brought under or in accordance with and
subject to the terms and conditions of this Agreement, or (ii) injunctive or
other equitable relief (other than for rescission or rescissory or similar
damages).  Notwithstanding any other provision contained in this Section 7.6,


                                       51
<PAGE>
 
none of the parties to this Agreement shall be deemed to have waived or
otherwise limited such party's rights on account of any fraudulent act by any of
the other parties hereto.  In addition and notwithstanding any limitation in
this Section to the applicability of this Section, each of the Sellers hereby
waives and releases the Company from any and all other claims or causes of
action, known and unknown, foreseen and unforeseen, which any of the Sellers may
have, as of the date of this Agreement, against the Company for any reason
whatsoever.

     7.7 Collateral Sources.  Indemnification under this Article VII shall not
         ------------------                                                   
be available to any Indemnified Party unless such Indemnified Party concurrently
seeks recovery from any Collateral Source for such claim.  Any Indemnifying
Party may, in its sole discretion, require any Indemnified Party to grant an
assignment of the right of such Indemnified Party to assert a claim against any
Collateral Source.  In the event of such assignment, the Indemnifying Party will
pursue such claim at its own expense.

     7.8 Certain Limitations.  Sellers hereby agree that if any payment by
         -------------------                                              
Sellers is made under the terms of this Agreement, Sellers shall have no rights
or causes of action against the Company or any director, officer, employee or
agent thereof, whether by reason of contribution, indemnification, subrogation,
set off or otherwise (including, without limitations, by reason of the making of
the Company of representations and warranties hereunder, it being understood and
agreed that the Company made such representations and warranties for the benefit
of Sellers), in respect of any such payments, any action or inaction at or prior
to the Closing Date, or in respect of any representation, warranty, covenant or
agreement made by the Company hereunder, and shall not take any action against
the Company or any director, officer, employee or agent thereof with respect


                                       52
<PAGE>
 
thereto.  Any such rights which Sellers may, by operation of law or otherwise,
have against the Company or any director, officer, employee or agent thereof
shall, at the Closing Date, be deemed to be hereby expressly and knowingly
waived.

                                 ARTICLE VIII

Securities Purchase Price (subject to any adjustment in accordance with Section
2.1(c)(ii) of this Agreement), or by the Sellers (including by sale of stock,

         ----------------------------                                          
Agreement is for the sole benefit of the parties hereto and their permitted
assigns and nothing herein expressed or implied shall give or be construed to
give to any Person, other than the parties hereto and such assigns, any legal or
equitable rights hereunder.

     8.3 Termination.
         ----------- 

         (a) This Agreement may be terminated by written notice given by Buyer
to Sellers or Sellers to Buyer (i) if the Closing shall not have occurred by
September 1, 1998, other than as a result of a material default by the party

7.2 of this Agreement and shall terminate at the close of business on the first

                         INDEPENDENT AUDITOR'S REPORT



To the Stockholders and
Board of Directors of
MEDICAL PARAMETERS, Inc.

We have audited the accompanying statements of financial position of MEDICAL
PARAMETERS, INC. as of February 28, 1998 and 1997, and the related statements of
earnings and cash flows for the years then ended.  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 audits 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 financial position of MEDICAL PARAMETERS, INC. as of
February 28, 1998 and 1997, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The additional information contained in
pages nine and ten is presented for purposes of additional analysis and is not a
required part of the basic financial statements.  Such information has been
subjected to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the basic financial statements taken as a whole.

                               FEBRUARY 28, 1998
                               -----------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
         ------------------------------------------

     A) NATURE OF BUSINESS
        ------------------

        The company develops and manufactures custom fluid high flow delivery
        systems for which some patents are acquired.  They also sell specialty
        medical products purchased from other medical device manufacturers.

     B) BASIS OF ACCOUNTING
        -------------------

        The company uses the accrual method of accounting. Sales revenues and
        commissions are recorded at the time of product shipment and expenses
        are recorded when incurred by the company.

     C) CONCENTRATION OF RISK
        ---------------------

        Amounts on deposit at a single financial institution occasionally exceed
        the $100,000 federally insured limit. As of February 28, 1998, the
        amounts on deposit exceeded the insured limit by $29,514.

     D) ESTIMATES
        ---------

        The preparation of financial statements in conformity with generally
        accepted accounting principles requires management to make estimates and
        assumptions that affect certain reported amounts and disclosures.
        Accordingly, actual results could differ from those estimates.

     E) CASH EQUIVALENTS
        ----------------

        The Company considers all highly liquid investments with a maturity of
        three months or less to be cash equivalents.  The Company has also
        included a small mutual fund in cash equivalents since it is readily
        convertible to cash and the balance is immaterial on the financial
        statements taken as a whole.

     F) INVENTORIES
        -----------

        The inventory is valued at the lower of cost (first-in, first-out
        method) or market. Inventories consist of:

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
         ------------------------------------------

         G) PROPERTY AND EQUIPMENT
            ----------------------

            The company depreciates its property and equipment over their
            estimated useful lives by the accelerated and straight line methods.

            Expenditures for maintenance and repairs are charged directly to the
            appropriate operating account at the time the expense is incurred.
            Expenditures representing additions, betterments, and capitalized
            lease obligations are included in property and equipment.

         H) S CORPORATION - INCOME TAX STATUS
            ---------------------------------

            The Company, with the consent of its shareholders, had elected under
            the Internal Revenue Code to be an S corporation effective March 1,
            1988. In lieu of corporate income taxes, the shareholders of an S
            corporation are taxed on their proportionate share of the Company's
            taxable income. Thus, no provision for federal income taxes and only
            the portion of state taxes payable by the corporation are included
            within these financial statements.

         I) ACCOUNTS RECEIVABLE
            -------------------

            The allowance for doubtful accounts is based on management's
            evaluation of outstanding accounts receivable at the end of the
            year. Due to the amount of bad debts incurred in fiscal year 1998 as
            noted below, management has decided to record an allowance of
            $10,000 for 1998. The allowance was zero for 1997 as management
            believed substantially all of the receivables would be collectible.
            Bad debts were $5,861 for 1998 and $389 for 1997.

NOTE 2 - RETAINED EARNINGS
         -----------------

         The components of retained earnings at the end of the year are as
 follows:

NOTE 3 - BUILDING RENTAL
         ---------------

         The Company conducts it operations from leased facilities. On March 10,
         1997, the Company entered into a new forty-one month lease, classified
         as an operating lease, which expires on August 31, 2000 with an option
         to renew for two additional years. The initial base rent was
         $121,439.41 payable in monthly installments. Also, as additional rent,
         the Company pays its proportionate share of the real estate taxes and
         operating costs of the building of which the premises are a part. The
         additional rent is included in the monthly payments. The total rent
         expense for the year was $206,410. The base rent increases February 1
         of each year as follows:

                      * 7 months only (2/l/00 - 8/31/00)

NOTE 4 - SALES
         -----

         During fiscal 1998, there was no one customer to whom sales of Walrus
         products or distributor products exceeded 10% of the corporation's
         sales. As noted below, the sale of distributor products was comprised
         primarily of Pall Biomedical products and the rights to this line were
         sold during the year.

NOTE 5 - SUPPLIERS
         ---------

         Elcam Plastics, an Israeli company, provided 39% and NP Medical, Inc.
         provided 16% of the material purchases during fiscal 1998 for Walrus
         Products. No other company supplied more than 10% of Walrus materials
         purchased.

         Pall Biomedical Inc. accounted for virtually all of the distributor
         products purchased during the current year. As noted below, the rights
         to this line were sold during the year.

NOTE 6 - EXTRAORDINARY ITEMS
         -------------------

         During 1997, the Company incurred legal, investment banking and
         accounting fees in relation to a proposed sale of substantially all of
         its assets to an outside third party. Several issues could not be
         resolved and the sale was never consummated.

         During 1998, the Company sold its rights to the exclusive distribution
         of Pall Corporation products in a certain territory to an unrelated
         corporation. The Company received $225,000 at the time of the sale and
         will receive another $225,000 subject to certain contingencies.

NOTE 7 - NOTES PAYABLE - BANK
         --------------------

         Currently, the corporation has three agreements with Woburn National
         Bank for financing. The first is a $750,000 revolving line of credit
         which carries interest set at prime plus 1.0% and is evidenced by a
         demand note. The second is a $633,312 sixty month term loan with
         interest set at prime plus 2.0% and matures on August 20, 2000. The
         third is a $150,000 thirty-six month term loan with interest set at
         prime plus 2.0% and matures on August 20, 1998. These loans are secured
         by a first security interest on "all business assets" and have the
         unconditional guaranty of A. Walter MacEachern and Michael A. Russell.

         The corporation is in compliance with all loan covenants as of February
         28, 1998.

         The balance of each loan on February 28, 1998 is:

disbursement hereunder from the date such disbursement is made by Bank;
provided, however, that to the extent this Note represents a replacement,
substitution, renewal or refinancing of existing indebtedness, interest shall
accrue from the date hereof.

               (b) Interest Rate Options.  Borrower shall have the option of
                   ---------------------                                    
choosing a fixed rate of interest from time to time, as quoted by the Bank,
which fixed rate of interest will apply for a period from 7 to 180 days, in 7 or
30 day increments, for any portion of the unpaid principal balance of this Note,
so long as such portion exceeds One Million Dollars ($1,000,000). Any
outstanding principal balance for which a fixed rate of interest option is in
effect will be subject to the principal payment penalty set forth in Section
1(c) below.

               (c) Principal Payment Penalty.  If the Borrower pays any portion
                   -------------------------                                   
of the principal balance of this Note at a time when interest accrues on such
principal portion at a fixed rate in accordance with Section 1(b) above,
Borrower shall indemnify Bank against Bank's loss or expense in employing
deposits as a consequence of such payment ("Indemnified Loss or Expense"). The
amount of such Indemnified Loss or Expense shall be determined by Bank based
upon the assumption that Bank funded 100% of such principal portion in the
London Interbank Market.



                                       1
<PAGE>
 
Any such payment will also be accompanied by payment of all accrued and unpaid
interest due to the date of payment on the principal amount paid and all other
fees, expenses and other sums due and owing under this Note.

               (d) Prime Rate.  "Prime Rate" means a floating annual rate of
                   ----------                                               
interest that is designated from time to time by Bank as the Prime Rate and is
used by Bank as a reference base with respect to different interest rates
charged to borrowers generally. The interest rate payable hereunder shall change
simultaneously with and automatically upon Bank's designation of any change in
such reference rate. Bank's determination and designation from time to time of
the reference rate shall not in any way preclude Bank from making loans to other
borrowers at a rate which is higher or lower than or different from the
reference rate.

         2.  Maximum Legal Rate.  Borrower shall not be obligated to pay and 
             ------------------                                         
Bank shall not collect interest at a rate in excess of the maximum permitted by
law or the maximum that will not subject Bank to any civil or criminal
penalties. If Borrower is required to pay interest at a rate in excess of such
maximum rate, the rate of interest shall immediately and automatically be
reduced to such maximum rate, and any payment made in excess of such maximum
rate, together with interest thereon at the rate provided herein from the date
of such payment, shall be immediately and automatically applied to the reduction
of the unpaid principal balance of this Note as of the date on which such excess
payment was made.

         3.  Loan Records.  The actual amounts due and owing from time to time
             ------------                                                
under this Note shall be evidenced by Bank's books and records of receipts and
disbursements hereunder. Bank shall set up and establish an account on the books
of Bank on which will be recorded advances under this Note and evidenced hereby,
payments on such advances and other appropriate debits and credits as provided
herein. Bank shall also record, in accordance with customary accounting
practice, all other interest, charges, expenses and other items properly
chargeable to Borrower hereunder, and other appropriate debits and credits. Such
books and records of Bank shall be presumed to be complete and accurate and
shall be deemed correct, except to the extent shown by Borrower to be manifestly
erroneous. The proceeds of any advance may be credited by Bank to a deposit
account of any Borrower or disbursed in any other manner requested by Borrower
and approved by Bank. All payments due under this Note are to be made in
immediately available funds. If Bank accepts payment in any other form, such
payment shall not be deemed to have been made until the funds comprising such
payment have actually been received or made available to Bank.

         4.  Collateral.  As security for all indebtedness to Bank now or
             ----------                                                  
hereafter incurred by Borrower, under this Note or otherwise, Borrower grants
Bank a lien upon and security interest


                                       2
<PAGE>
 
in any securities, instruments or other personal property of Borrower now or
hereafter in Bank's possession and in any deposit balances now or hereafter held
by Bank for Borrower's account and all proceeds of any such personal property or
deposit balances. Such liens and security interests shall be independent of
Bank's right of setoff. This Note and the indebtedness evidenced hereby shall be
additionally secured by any lien or security interest evidenced by a writing
(whether now existing or hereafter executed) which contains a provision to the
effect that such lien or security interest is intended to secure (a) this Note
or the indebtedness evidenced hereby, or (b) any category of liabilities,
obligations or the indebtedness of Borrower to Bank which includes this Note or
the indebtedness evidenced hereby, and all property subject to any such lien or
security interest shall be collateral for this Note.

         5.  Replacement.  Borrower acknowledges and agrees that this Note
             -----------                                                  
replaces and supersedes the two (2) promissory notes previously executed (a) by
Borrower dated January 29, 1996 in favor of Bank, and (b) by Borrower, Arrow
Medical Products, Inc., and Arrow International Export Corporation dated July
17, 1996 in favor of Bank in the principal amount of $45,000,000.

         6.  Application of Payments.  All payments shall be applied first to
             -----------------------                                      
the payment in full of any costs incurred in the collection of any sum due under
this Note, including (without limitation) reasonable attorneys' fees, then to
the payment in full of any late charges, then to the payment in full of accrued,
unpaid interest and finally to the reduction of the unpaid principal balance of
this Note.

         7.  Default: Rights, Remedies.
             ------------------------- 

               (a) Events of Default.  The following shall constitute Events of

     principal of or accrued interest on this Note when due.

                   (ii)  Default Under Other Obligations.  The Borrower:
                         -------------------------------      

                         (A) defaults in any payment of principal of or interest
         on any obligations for borrowed money (other than under the Note) or
         for the deferred purchase price of property beyond any period of grace
         provided with respect thereto; or

                         (B) defaults in the performance of any other agreement,
         term or condition contained in any such obligation or in any agreement
         relating thereto, if the effect of such default is to cause, or to
         permit the holder or holders of such obligation (or a trustee


                                       3

         on behalf of such holder or holders) to then cause, such obligation to
         become due prior to its stated maturity.

                    (iii) Default Under Other Documents.  An "Event of Default"
                          -----------------------------
or similar event shall have occurred and be continuing under any other note,
loan agreement or loan document regarding credit facilities extended to Borrower
by Bank.

                    (iv)  Voluntary Bankruptcy, Etc.  The commencement by the 
                          -------------------------                    
Borrower of a voluntary case under the United States Bankruptcy Code, as now
constituted or hereafter amended, or any other applicable federal or state
bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or
the consent by it to the appointment of or taking possession by a receiver,
liquidator, assignee, trustee, custodian, sequestrator (or other similar
official) of the Borrower or for any substantial part of its property, or the
making by it of any assignment for the benefit of creditors, or the failure of
the Borrower generally to pay its debts as such debts become due, or the taking
of corporate action by the Borrower in furtherance of any of the foregoing.

                    (v)   Involuntary Bankruptcy, Etc.  The entry of a decree or
                          ---------------------------
order for relief by a court having jurisdiction in the premises in respect of
the Borrower in an involuntary case under the United States Bankruptcy Code, as
now or hereafter constituted, or any other applicable federal or state
bankruptcy, insolvency or other similar law, or appointing a receiver,
liquidator, assignee, custodian, trustee, sequestrator (or similar official) of
the Borrower or for any substantial part of its property, or ordering the
winding-up or liquidation of its affairs and the continuance of any such decree
or order unstayed and in effect for a period of thirty (30) days.

               (b) Acceleration.
                   ------------ 

                    (i)   Upon the occurrence of an Event of Default specified
in Sections 7(a)(i) through 7.1(a)(iii), Bank may, by written notice to
Borrower, terminate immediately and irrevocably the credit facility evidenced by
this Note and declare this Note to be due and payable, whereupon the principal
amount of this Note, together with accrued interest hereon and all other amounts
payable hereunder, shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly
waived, anything contained herein or in the documents evidencing the same to the
contrary notwithstanding.

                    (ii)  Upon the occurrence of an Event of Default specified
in Sections 7(a)(iv) and 7(a)(v), the credit facility evidenced by this Note
shall automatically and immediately terminate and the unpaid principal balance
of, all accrued, unpaid interest on, and all other sums payable with regard to,
this Note shall automatically and immediately become due and payable, in all
cases without any action on the part of the Bank.

                    (c)   Remedies.  Upon the occurrence of an Event of Default,
                          --------
Bank may, immediately or at any time thereafter, exercise any or all of its
rights hereunder or under any agreement or otherwise under applicable law
against Borrower, against any person liable, either absolutely or contingently,
for payment of any indebtedness evidenced hereby, and in any collateral, and
such rights may be exercised in any order and shall not be prejudiced by any
delay in Bank's exercise thereof. At any time after an Event of Default, Bank
may, at its option and upon five (5) days written notice to Borrower, begin
accruing interest on this Note at a rate not to exceed three percent (3%) per
annum in excess of the rate of interest provided for above on the unpaid
principal balance hereof. All such additional interest shall be payable upon
demand. In addition, Borrower shall be liable and responsible for any and all
costs and expenses incurred by Bank in connection with the enforcement of this
Note and the collection of sums due under this Note, including attorneys, fees
incurred by Bank (which shall include any such fees incurred by Bank in any
bankruptcy proceeding of Borrower).

               THE FOLLOWING PARAGRAPH SETS FORTH A WARRANT OF ATTORNEY TO
     CONFESS JUDGMENT AGAINST THE BORROWER. IN GRANTING THIS WARRANT OF ATTORNEY
     TO CONFESS JUDGMENT AGAINST THE BORROWER, THE BORROWER HEREBY KNOWINGLY,
     INTELLIGENTLY AND VOLUNTARILY, AND, ON THE ADVICE OF SEPARATE COUNSEL OF
     THE BORROWER, UNCONDITIONALLY WAIVES, ANY AND ALL RIGHTS THE BORROWER HAS
     OR May HAVE TO PRIOR NOTICE AND AN OPPORTUNITY FOR HEARING UNDER THE
     RESPECTIVE CONSTITUTIONS AND LAWS OF THE UNITED STATES AND THE COMMONWEALTH
     OF PENNSYLVANIA.

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

release of errors, for which this Note or a copy hereof shall serve as a 
- ------------------------------------------------------------------------
sufficient warrant.  This power to enter judgment against Borrower shall not be
- -------------------------------------------------------------------------------
exhausted by any exercise of the power and shall continue from time to time and 
- -------------------------------------------------------------------------------
at all times until full payment of all amounts due under this Note.
- ------------------------------------------------------------------

                    (e)   Remedies Cumulative.  The remedies of Bank shall be 
                          -------------------
cumulative and concurrent, and may be pursued singly, successively, or together,
at its sole discretion, and may be exercised as often as the occasion therefor
shall occur; and the failure to exercise any such right or remedy shall in no
event be construed as a waiver or release thereof.

          8.   Year 2000 Compatibility.  Borrower shall take all action
               -----------------------                                 
necessary to ensure that Borrower's computer-based systems are able to operate
and effectively process data including dates on and after January 1, 2000.  At
the request of Bank, Borrower shall provide Bank assurance acceptable to Bank of
Borrower's Year 2000 compatibility.

          9.   Waivers.  Borrower and all guarantors of and sureties for this
               -------                                                       
Note waive presentment for payment, demand, notice of dishonor, protest, and
notice of protest with regard to this Note, all errors, defects and
imperfections in any proceedings instituted by Bank under the terms of this
Note, and all benefit that might accrue to Borrower by virtue of any present or
future laws exempting any property, real or personal, or any part of the
proceeds arising from any sale of any such property, from attachment, levy, or
sale under execution, or providing for any stay of execution, exemption from
civil process, or extension of time for payment; and Borrower agrees that any
real estate that may be levied upon pursuant to a judgment obtained by virtue
hereof, on any writ of execution issued thereon, may be sold upon any such writ
in whole or in part in any order desired by Bank.

          10.  Unconditional Liability.  Borrower and all endorsers, sureties

and guarantors hereby jointly and severally waive all other notices in
connection with the delivery, acceptance, performance, default, or enforcement
of the payment of this Note, and they agree that the liability of each of them
shall be unconditional, without regard to the liability of any other party, and
shall not be affected in any manner by any indulgence, extension of time,
renewal, waiver or modification granted or consented to by Bank, and consent to
any and all extensions of time, renewals, waivers, or modifications that may be
granted by Bank with respect to the payment or other provisions of this Note,
and to the release of any part of any collateral, with or without substitution,
and agree that additional makers, endorsers, guarantors, or sureties may become
parties hereto without notice to them or affecting their liability hereunder.

          11.  Construction.  This Note shall be construed and enforced in
               ------------                                               
accordance with the domestic, internal law, but not the law of conflict of laws,
of the Commonwealth of Pennsylvania.  The captions preceding the text of the
paragraphs of this Note are inserted only for convenience of reference and shall
not constitute a part of this Note, nor shall they in any way affect its
meaning, construction or effect.

          12.  Severabilitv.  Any provision contained in this Note which is
               ------------                                                
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.


          13.  Arbitration.
               ----------- 

               (a)   Upon demand of Borrower or Bank, whether made before or
after institution of any judicial proceeding, any dispute, claim or controversy
arising out of, connected with or relating to this Note and any advances made
hereunder ("Disputes") shall be resolved by binding arbitration as provided
herein. Institution of a judicial proceeding does not waive the right of the
party instituting the proceeding to demand arbitration hereunder. Disputes may
include, without limitation, tort claims, counterclaims, disputes as to whether
a matter is subject to arbitration, claims brought as class actions, claims
arising from documents executed in the future, or claims arising out of or in
connection with the transactions reflected by this Note.

               (b)   Arbitration shall be conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the
American Arbitration Association (the "AAA") and Title 9 of the U.S. Code.  All
arbitration hearings shall be conducted in the City of Philadelphia.  The
expedited procedures set forth in Rule 51 et seq. of the Arbitration Rules shall
                                          -- ---                                
be applicable to claims of less than $1,000,000.  All applicable statutes of
limitation shall apply to any Dispute.  A judgment upon the award may be entered
in any court having jurisdiction.  The panel from which all arbitrators are
selected shall be comprised of licensed attorneys.  The single arbitrator
selected for expedited procedure shall be a retired judge from the highest court
of general jurisdiction, state or federal, of the state where the hearing will
be conducted or if such person is not available to serve, the single arbitrator
may be a licensed attorney.  Notwithstanding the foregoing, this arbitration
provision does not apply to disputes under or related to swap agreements.

               (c)   Notwithstanding the preceding binding arbitration
provisions, Borrower and Bank agree to preserve, without diminution, certain
remedies that Borrower and Bank shall employ or exercise freely, independently
or in connection with an arbitration proceeding or after an arbitration action
is brought. Bank and Borrower shall have the right to proceed in any court of
proper jurisdiction or by self-help to exercise or prosecute the following
remedies, as applicable: (i) all rights to foreclose against any real or
personal property or other security by exercising a power of sale granted under
the Note or any other


                                       7
<PAGE>
 
documents or under applicable law or by judicial foreclosure and sale, including
a proceeding to confirm the sale; (ii) all rights of self-help including
peaceful occupation of real property and collection of rents, set-off, and
peaceful possession of personal property; (iii) obtaining provisional or
ancillary remedies including injunctive relief, sequestration, garnishment
attachment, appointment of receiver and filing an involuntary bankruptcy
proceeding; and (iv) when applicable, a judgment by confession of judgment.
Preservation of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a Dispute.

               (d)   Borrower agrees that it shall not have a remedy of punitive
or exemplary damages against Bank in any Dispute and hereby waives any right or
claim to punitive or exemplary damages it has now or which may arise in the
future in connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

          14.  Successors and Assigns.  The provisions of this Note shall bind
               ----------------------                                         
and inure to the benefit of Borrower and Bank and their respective successors
and permitted assigns.

          IN WITNESS WHEREOF, Borrower, intending to be legally bound hereby,
has caused this Note to be duly executed by its authorized officers the day and
year first above written.

(THE "BORROWER"), AND GIVEN TO FIRST UNION NATIONAL BANK (THE "CREDITOR"), IN

CAREFULLY READS AND UNDERSTANDS THIS DOCUMENT.  WHEN THE BORROWER SIGNS ITS NAME

Borrower and to exercise rights of execution, levy, garnishment, seizure of the
Borrower's property and the like.  Other than notices required under the Loan
Documents, these rights and powers may be exercised by the Creditor without
giving the Borrower any prior notice of its intention to do so.  In addition,
certain of these powers and rights may be exercised in Pennsylvania (regardless
where the Borrower resides) without a prior hearing of any kind, and without a
jury trial.

     relevant Transaction has occurred or been effectively designated and (3)
     each other applicable condition precedent specified in this Agreement.

(b)  Change of Account. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c)  Netting. If on any date amounts would otherwise be payable:

     (i)  in the same currency; and

     (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction.  The election may be
made in the Schedule or a Confirmation by specifying that subparagraph (ii)
above will not apply to the Transactions identified as being subject to the
election, together with the starting date (in which case subparagraph (ii) above
will not, or will cease to, apply to such Transactions from such date).  This
election may be made separately for different groups of Transactions and will
apply separately to each pairing of branches or offices through which the
parties make and receive payments or deliveries.

(d)  Default Interests; Other Amounts.  Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgment) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence of effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3.   REPRESENTATIONS

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered
into) that:

(a)  Basic Representations.

     (i)   Status.  It is duly organised and validly existing under the laws of
     the jurisdiction of its organisation or incorporation and, if relevant
     under such laws, in good standing;

     (ii)  Powers. It has the power to execute this Agreement and any other
     documentation relating to this Agreement to which it is a party, to deliver
     this Agreement and any other documentation relating to this Agreement that
     it is required by this Agreement to deliver and to perform its obligations
     under this Agreement and any obligations it has under any Credit Support
     Document to which it is a party and has taken all necessary action to
     authorise such execution, delivery and performance;

     (iii) No Violation or Conflict. Such execution, delivery and performance do
     not violate or conflict with any law applicable to it, any provision of its
     constitutional documents, any order or judgment of any court or other
     agency of government applicable to it or any of its assets or any
     contractual restriction binding on or affecting it or any of its assets:



                                       2
<PAGE>
 
     (iv)  Consents.  All governmental and other consents that are required to 
     have been obtained by it with respect to this Agreement or any Credit
     Support Document to which it is a party have been obtained and are in full
     force and effect and all conditions of any such consents have been complied
     with; and

     (v)   Obligations Binding.  Its obligations under this Agreement and any 
     Credit Support Document to which it is a party constitute its legal, valid
     and binding obligations, enforceable in accordance with their respective
     terms (subject to applicable bankruptcy, reorganisation, insolvency,
     moratorium or similar affecting creditors' rights generally and subject, as
     to enforceability, to equitable principles of general application
     (regardless of whether enforcement is sought in a proceeding in equity or
     at law)).

(b)  Absence of Certain Events.  No Event of Default or Potential Event of
Default or, to its knowledge, Termination Event with respect to it has occurred
and is continuing and no such event or circumstance would occur as a result of
its entering into or performing its obligations under this Agreement or any
Credit Support Document to which it is a party.

(c)  Absence of Litigation.  There is not pending or, to its knowledge,
threatened against it or any of its Affiliates any action, suit or proceeding at
law or in equity or before any court, tribunal, governmental body, agency or
official or any arbitrator that is likely to affect the legality, validity or
enforceability against it of this Agreement of any Credit Support Document to
which it is a party or its ability to perform its obligations under this
Agreement or such Credit Support Document.

(d)  Accuracy of Specified Information.  All applicable information that is
furnished in writing by or on behalf of it to the other party and is identified
for the purpose of this Section 3(d) in the Schedule is, as of the date of the
information, true, accurate and complete in every material respect.

4.   AGREEMENTS

Each party agrees with the other that, so long as either party has or may have
any obligation under this Agreement or under any Credit Support Document to
which it is a party:

(a)  Furnish Specified Information.  It will deliver to the other party any
forms, documents or certificates specified in the Schedule or any Confirmation
by the date specified in the Schedule or such Confirmation or, if none is
specified, as soon as reasonably practicable.

(b)  Maintain Authorisations. It will use all reasonable efforts to maintain in
full force and effect all consents of any governmental or other authority that
are required to be obtained by it with respect to this Agreement or any Credit
Support Document to which it is a party and will use all reasonable efforts to
obtain any that may become necessary in the future.

(c)  Comply with Laws.  It will comply in all material respects with all
applicable laws and orders to which it may be subject if failure so to comply
would materially impair its ability to perform its obligations under this
Agreement or any Credit Support Document to which it is a party.

5.   EVENTS OF DEFAULT AND TERMINATION EVENTS

(a)  Events of Default. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any of the following events constitutes an event of default (an
"Event of Default") with respect to such party:

     (i)   Failure to Pay or Deliver.  Failure by the party to make, when due, 
     any payment under this Agreement or delivery under Section 2(a)(i) or 2(d)
     required to be made by it if such failure is not remedied on or before the
     third Local Business Day after notice of such failure is given to the
     party;

     (ii)  Breach of Agreement.  Failure by the party to comply with or perform
     any agreement or obligation (other than an obligation to make any payment
     under this Agreement or delivery under Section 2(a)(i) or 2(d) or to give
     notice of a Termination Event) to be complied with or performed



                                       3
<PAGE>
 
     by the party in accordance with this Agreement if such failure is not
     remedied on or before the thirtieth day after notice of such failure is
     given to the party;

     (iii) Credit Support Default.

           (1) Failure by the party or any Credit Support Provider of such party
           to comply with or perform any agreement or obligation to be complied
           with or performed by it in accordance with any Credit Support
           Document if such failure is continuing after any applicable grace
           period has elapsed;

           (2) the expiration or termination of such Credit Support Document or
           the failing or ceasing of such Credit Support Document to be in full
           force and effect for the purpose of this Agreement (in either case
           other than in accordance with its terms) prior to the satisfaction of
           all obligations of such party under each Transaction to which such
           Credit Support Document relates without the written consent of the
           other party; or

           (3) the party or such Credit Support Provider disaffirms, disclaims,
           repudiates or rejects, in whole or in part, or challenges the
           validity of, such Credit Support Document;

     (iv)  Misrepresentation.  A representation made or repeated or deemed to
     have been made or repeated by the party or any Credit Support Provider of
     such party in this Agreement or any Credit Support Document proves to have
     been incorrect or misleading in any material respect when made or repeated
     or deemed to have been made or repeated;

     (v)   Default under Specified Transaction.  The party, any Credit Support
     Provider of such party or any applicable Specified Entity of such party (1)
     defaults under a Specified Transaction and, after giving effect to any
     applicable notice requirement or grace period, there occurs a liquidation
     of, an acceleration of obligations under, or an early termination of, that
     Specified Transaction, (2) defaults, after giving effect to any applicable
     notice requirement or grace period, in making any payment or delivery due
     on the last payment, delivery or exchange date of, or any payment on early
     termination of, a Specified Transaction (or such default continues for at
     least three Local Business Days if there is no applicable notice
     requirement or grace period) or (3) disaffirms, disclaims, repudiates or
     rejects, in whole or in part, a Specified Transaction (or such action is
     taken by any person or entity appointed or empowered to operate it or act
     on its behalf);

     (vi)  Cross Default.  If "Cross Default" is specified in the Schedule as
     applying to the party, the occurrence or existence of (1) a default, event
     of default or other similar condition or event (however described) in
     respect of such party, any Credit Support Provider of such party or any
     applicable Specified Entity of such party under one or more agreements or
     instruments relating to Specified Indebtedness of any of them (individually
     or collectively) in an aggregate amount of not less than the applicable
     Threshold Amount (as specified in the Schedule),which has resulted in such
     Specified Indebtedness becoming, or becoming capable at such time of being
     declared, due and payable under such agreements or instruments, before it
     would otherwise have been due and payable or (2) a default by such party,
     such Credit Support Provider or such Specified Entity (individually or
     collectively) in making one or more payments on the due date thereof in an
     aggregate amount of not less than the applicable Threshold Amount under
     such agreements or instruments (after giving effect to any applicable
     notice requirement or grace period);

     (vii) Bankruptcy.  The party, any Credit Support Provider of such party or
     any applicable Specified Entity of such party:--

           (1) is dissolved (other than pursuant to a consolidation,
           amalgamation or merger); (2) becomes insolvent or is unable to pay
           its debts or fails or admits in writing its inability generally to
           pay its debts as they become due; (3) makes a general assignment,
           arrangement or composition with or for the benefit of its creditors;
           (4) institutes or has instituted against it a proceeding seeking a
           judgment of insolvency or bankruptcy or any other relief under any
           bankruptcy or insolvency law or other similar law affecting
           creditors' rights, or a petition is presented for its



                                       4
<PAGE>
 
           winding-up or liquidation, and, in the case of any such proceeding or
           petition instituted or presented against it, such proceeding or
           petition (A) results in a judgment of insolvency or bankruptcy or the
           entry of an order for relief or the making of an order for its
           winding-up or liquidation or (B) is not dismissed, discharged, stayed
           or restrained in each case within 30 days of the institution or
           presentation thereof; (5) has a resolution passed for its winding-up,
           official management or liquidation (other than pursuant to a
           consolidation, amalgamation or merger); (6) seeks or becomes subject
           to the appointment of an administrator, provisional liquidator,
           conservator, receiver, trustee, custodian or other similar official
           for it or for all or substantially all its assets; (7) has a secured
           party take possession of all or substantially all its assets or has a
           distress, execution, attachment, sequestration or other legal process
           levied, enforced or sued on or against all or substantially all its
           assets and such secured party maintains possession, or any such
           process is not dismissed, discharged, stayed or restrained, in each
           case within 30 days thereafter; (8) causes or is subject to any event
           with respect to it which, under the applicable laws of any
           jurisdiction, has an analogous effect to any of the events specified
           in clauses (1) to (7) (inclusive); or (9) takes any action in
           furtherance of, or indicating its consent to, approval of, or
           acquiescence in, any of the foregoing acts; or

     (viii)Merger Without Assumption.  The party or any Credit Support Provider
     of such party consolidates or amalgamates with, or merges with or into, or
     transfers all or substantially all its assets to, another entity and, at
     the time of such consolidation, amalgamation, merger or transfer:

           (1)  the resulting, surviving or transferee entity fails to assume
           all the obligations of such party or such Credit Support Provider
           under this Agreement or any Credit Support Document to which it or
           its predecessor was a party by operation of law or pursuant to an
           agreement reasonably satisfactory to the other party to this
           Agreement; or

           (2)  the benefits of any Credit Support Document fail to extend
           (without the consent of the other party) to the performance by such
           resulting, surviving, or transferee entity of its obligations under
           this Agreement.

(b)  Termination Events.  The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, and, if specified to be applicable, a Credit
Event Upon Merger if the event is specified pursuant to (ii) below or an
Additional Termination Event if the event is specified pursuant to (iii) below:

     (i)   Illegality.  Due to the adoption of, or any change in, any applicable
     law after the date on which a Transaction is entered into, or due to the
     promulgation of, or any change in, the interpretation by any court,
     tribunal or regulatory authority with competent jurisdiction of any
     applicable law after such date, it becomes unlawful (other than as a result
     of a breach by the party of Section 4(b)) for such party (which will be the
     Affected Party):

           (1)  to perform any absolute or contingent obligation to make a
           payment or delivery or to receive a payment or delivery in respect of
           such Transaction or to comply with any other material provision of
           this Agreement relating to such Transaction; or

           (2)  to perform, or for any Credit Support Provider of such party to
           perform, any contingent or other obligation which the party (or such
           Credit Support Provider) has under any Credit Support Document
           relating to such Transaction;

     (ii)  Credit Event Upon Merger.  If "Credit Event Upon Merger" is specified
     in the Schedule as applying to the party, such party ("X"), any Credit
     Support Provider of X or any applicable Specified Entity of X consolidates
     or amalgamates with, or merges with or into, or transfers all or
     substantially all its assets to, another entity and such action does not
     constitute an event described in Section 5(a)(viii) but the
     creditworthiness of the resulting, surviving or transferee entity is
     materially weaker than that of X, such Credit Support Provider or such
     Specified Entity, as the case may be, immediately prior to such action
     (and, in such events X or its successor or transferee, as appropriate, will
     be the Affected Party); or

                                       5
<PAGE>
 
     (iii) Additional Termination Event.  If any "Additional Termination Event"
     is specified in the Schedule or any Confirmation as applying, the
     occurrence of such event (and, in such event, the Affected Party or
     Affected Parties shall be as specified for such Additional Termination
     Event in the Schedule or such Confirmation).


(c)  Event of Default and Illegality.  If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.


6.   EARLY TERMINATION

(a)  Right to Terminate Following Event of Default.  If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b)  Right to Terminate Following Termination Event.

     (i)   Notice.  If a Termination Event occurs, an Affected Party will,
     promptly upon becoming aware of it, notify the other party, specifying the
     nature of that Termination Event and each Affected Transaction and will
     also give such other information about that Termination Event as the other
     party may reasonably require.

     (ii)  Two Affected Parties.  If an Illegality under Section 5(b)(i)(1)
     occurs and there are two Affected Parties, each party will use all
     reasonable efforts to reach agreement within 30 days after notice thereof
     is given under Section 6(b)(i) on action to avoid that Termination Event.

     (iii) Right to Terminate.  If:--

           (1)  an agreement under Section 6(b)(ii) has not been effected with
           respect to all Affected Transactions within 30 days after an Affected
           Party gives notice under Section 6(b)(1); or

           (2)  an Illegality other than that referred to in Section 6(b)(ii), a
           Credit Event Upon Merger or an Additional Termination Event occurs.

     either party in the case of an Illegality, any Affected Party in the case
     of an Additional Termination Event if there is more than one Affected
     Party, or the party which is not the Affected Party in the case of a Credit
     Event Upon Merger or an Additional Termination Event if there is only one
     Affected Party may, by not more than 20 days notice to the party and
     provided that the relevant Termination Event is then continuing, designate
     a day not earlier than the day such notice is effective as an Early
     Termination Date in respect of all Affected Transactions.

(c)  Effect of Designation.

     (i)   If notice designating an Early Termination Date is given under
     Section 6(a) or (b), the Early Termination Date will occur on the date so
     designated, whether or not the relevant Event of Default or Termination
     Event is then continuing.


                                       6
<PAGE>
 
     (ii)  Upon the occurrence or effective designation of an Early Termination
     Date, no further payments or deliveries under Section 2(a)(i) or 2(d) in
     respect of the Terminated Transactions will be required to be made, but
     without prejudice to the other provisions of this Agreement. The amount, if
     any, payable in respect of an Early Termination Date shall be determined
     pursuant to Section 6(e).

(d)  Calculations.

     (i)  Statement.  On or as soon as reasonably practicable following the
     occurrence of an Early Termination Date, each party will make the
     calculations on its part, if any, contemplated by Section 6(e) and will
     provide to the other party a statement (1) showing, in reasonable detail,
     such calculations (including all relevant quotations and specifying any
     amount payable under Section 6(e)) and (2) giving details of the relevant
     account to which any amount payable to it is to be paid. In the absence of
     written confirmation from the source of a quotation obtained in determining
     a Market Quotation, the records of the party obtaining such quotation will
     be conclusive evidence of the existence and accuracy of such quotation.

     (ii) Payment Date.  An amount calculated as being due in respect of any
     Early Termination Date under Section 6(e) will be payable on the day that
     notice of the amount payable is effective (in the case of an Early
     Termination Date which is designated or occurs as a result of an Event of
     Default) and on the day which is two Local Business Days after the day on
     which notice of the amount payable is effective (in the case of an Early
     Termination Date which is designated as a result of a Termination Event).
     Such amount will be paid together with (to the extent permitted under
     applicable law) interest thereon (before as well as after judgment), from
     (and including) the relevant Early Termination Date to (but excluding) the
     date such amount is paid, at the Applicable Rate. Such interest will be
     calculated on the basis of daily compounding and the actual number of days
     elapsed.

(e)  Payments on Early Termination.  If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off.

     (i)   Events of Default.  If the Early Termination Date results from an 
     Event of Default:--

           (1)  First Method and Market Quotation.  If the First Method and
           Market Quotation apply, the Defaulting Party will pay to the Non-
           defaulting Party the excess, if a positive number, of (A) the sum of
           the Settlement Amount (determined by the Non-defaulting Party) in
           respect of the Terminated Transactions and the Unpaid Amounts owing
           to the Non-defaulting Party over (B) the Unpaid Amounts owing to the
           Defaulting Party.

           (2)  First Method and Loss.  If the First Method and Loss apply, the
           Defaulting Party will pay to the Non-Defaulting Party, if a positive
           number, the Non-defaulting Party's Loss in respect of this Agreement.

           (3)  Second Method and Market Quotation.  If the Second Method and
           Market Quotation apply, an amount will be payable equal to (A) the
           sum of the Settlement Amount (determined by the Non-defaulting Party)
           in respect of the Terminated Transactions and the Unpaid Amounts
           owing to the Non-defaulting Party less (B) the Unpaid Amounts owing
           to the Defaulting Party. If that amount is a positive number, the
           Defaulting Party will pay it to the Non-defaulting Party; if it is a
           negative number, the Non-defaulting Party will pay the absolute value
           of that amount to the Defaulting Party.

           (4)  Second Method and Loss.  If the Second Method and Loss apply, an
           amount will be payable equal to the Non-defaulting Party's Loss in
           respect of this Agreement. If that amount is a positive number, the
           Defaulting Party will pay it to the Non-defaulting Party; if it is a
           negative



                                       7
<PAGE>
 
           number, the Non-defaulting Party will pay the absolute value of that
           amount to the Defaulting Party.

     (ii)  Termination Events.  If the Early Termination Date results from a
     Termination Event:--

           (1)  One Affected Party.  If there is one Affected Party, the amount
           payable will be determined in accordance with Section 6(e)(i)(3), if
           Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
           except that, in either case, references to the Defaulting Party and
           to the Non-defaulting Party will be deemed to be references to the
           Affected Party and the party which is not the Affected Party,
           respectively, and, if Loss applies and fewer than all the
           Transactions are being terminated, Loss shall be calculated in
           respect of all Terminated Transactions.

           (2)  Two Affected Parties.  If there are two Affected Parties:

                (A)  if Market Quotation applies, each party will determine a
                Settlement Amount in respect of the Terminated Transactions, and
                an amount will be payable equal to (I) the sum of (a) one-half
                of the difference between the Settlement Amount of the party
                with the higher Settlement Amount ("X") and the Settlement
                Amount of the party with the lower Settlement Amount ("Y") and
                (b) the Unpaid Amounts owing to X less (II) the Unpaid Amounts
                owing to Y; and

                (B)  if Loss applies, each party will determine its Loss in
                respect of this Agreement (or, if fewer than all the
                Transactions are being terminated, in respect of all Terminated
                Transactions) and an amount will be payable equal to one-half of
                the difference between the Loss of the party with the higher
                Loss ("X") and the Loss of the party with the lower Loss ("Y").

           If the amount payable is a positive number, Y will pay it to X; if it
           is a negative number, X will pay the absolute value of that amount to
           Y.

     (iii) Adjustment for Bankruptcy.  In circumstances where an Early
     Termination Date occurs because "Automatic Early Termination" applies in
     respect of a party, the amount determined under this Section 6(e) will be
     subject to such adjustments as are appropriate and permitted by law to
     reflect any payments or deliveries made by one party to the other under
     this Agreement (and retained by such other party) during the period from
     the relevant Early Termination Date to the date for payment determined
     under Section 6(d)(ii).

     (iv)  Pre-Estimate.  The parties agree that if Market Quotation applies an
     amount recoverable under this Section 6(e) is a reasonable pre-estimate of
     loss and not a penalty. Such amount is payable for the loss of bargain and
     the loss of protection against future risks and except as otherwise
     provided in this Agreement neither party will be entitled to recover any
     additional damages as a consequence of such losses.

7.   TRANSFER

Neither this Agreement nor any interest or obligation in or under this Agreement
may be transferred (whether by way of security or otherwise) by either party
without the prior written consent of the other party , except that:--

(a)  a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b)  a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

Transactions, as the case may be, and a party, an amount that party reasonably
determines in good faith to be its total losses and costs (or gain, in which
case expressed as a negative number) in connection with this Agreement or that

                                       11
<PAGE>
 
resulting from any of them). Loss includes losses and costs (or gains) in
respect of any payment or delivery required to have been made (assuming
satisfaction of each applicable condition precedent) on or before the relevant
Early Termination Date and not made, except, so as to avoid duplication, if
Section 6(e)(i)(1) or (3) or 6(e)(ii)(2)(A) applies.  Loss does not include a

party will determine its Loss as of the relevant Early Termination Date, or, if
that is not reasonably practicable, as of the earliest date thereafter as is
reasonably practicable.  A party may (but need not) determine its Loss by
reference to quotations of relevant rates or prices from one or more leading
dealers in the relevant markets.

"Market Quotation" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers.  Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference Market-
maker to enter into a transaction (the "Replacement Transaction") that would
have the effect of preserving for such party the economic equivalent of any
payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have been required after that date. For this
purpose, Unpaid Amounts in respect of the Terminated Transaction or group of
Terminated Transactions are to be excluded but, without limitation, any payment
or delivery that would, but for the relevant Early Termination Date, have been
required (assuming satisfaction of each applicable condition precedent) after
that Early Termination Date is to be included. The Replacement Transaction would
be subject to such documentation as such party and the Reference Market-maker
may, in good faith, agree.  The party making the determination (or its agent)
will request each Reference Market-maker to provide its quotation to the extent
reasonably practicable as of the same day and time (without regard to different
time zones) on or as soon as reasonably practicable after the relevant Early
Termination Date.  The day and time as of which those quotations are to be
obtained will be selected in good faith by the party obliged to make a
determination under Section 6(e), and, if each party is so obliged, after
consultation with the other.  If more than three quotations are provided, the
Market Quotation will be the arithmetic mean of the quotations, without regard
to the quotations having the highest and lowest values.  If exactly three such
quotations are provided, the Market Quotation will be the quotation remaining
after disregarding the highest and lowest quotations.  For this purpose, if more
than one quotation has the same highest value or lowest value, then one of such
quotations shall be disregarded.  If fewer than three quotations are provided,
it will be deemed that the Market Quotation in respect of such Terminated
Transaction or group of Terminated Transactions cannot be determined.

"Non-default Rate" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"Potential Event of Default" means any event which, with the giving of notice or
the lapse of time or both, would constitute an Event of Default.

among dealers of the highest credit standing which satisfy all the criteria that
such party applies generally at the time in deciding whether to offer or to make
an extension of credit and (b) to the extent practicable, from among such
dealers haying an office in the same city.

"Scheduled Payment Date" means a date on which a payment or delivery is to be
made under Section 2(a)(1) with respect to a Transaction.

"Set-off" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under



                                       12
<PAGE>
 
this Agreement, another contract, applicable law or otherwise) that is exercised
by, or imposed on. such payer.

"Settlement Amount" means, with respect to a Party and any Early Termination
Date, the sum of:

(a) the Market Quotations (whether positive or negative) for each Terminated
Transaction or group of Terminated Transactions for which a Market Quotation is
determined; and

(b)  such party's Loss (whether positive or negative and without reference to
any Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

present or future, contingent or otherwise, as principal or surety or otherwise)

swap transaction, currency option or any other similar transaction (including
any option with respect to any of these transactions), (b) any combination of
these transactions and (c) any other transaction identified as a Specified
Transaction in this Agreement or the relevant confirmation.

"Terminated Transactions" means with respect to any Early Termination Date (a)
if resulting from a Termination Event, all Affected Transactions and (b) if
resulting from an Event of Default, all Transactions (in either case) in effect
immediately before the effectiveness of the notice designating that Early
Termination Date (or, if "Automatic Early Termination" applies, immediately
before that Early Termination Date).

"Termination Event" means an Illegality or, if specified to be applicable, a
Credit Event Upon Merger or an Additional Termination Event.

cost (without proof or evidence of any actual cost) to each party (as emitted by
such party) if it were to fund or of funding such amounts.

"Unpaid Amounts" owing to any party means, with respect to an Early Termination
Date, the aggregate of (a) in respect of all Terminated Transactions, the
amounts that became payable (or that would have become payable but for Section
2(a)(iii)) to such party under Section 2(a)(i) on or prior to such Early
Termination Date and which remain unpaid as at such Early Termination Date and
(b) in respect of each Terminated Transaction, for each obligation under Section
2(a)(i) which was (or would have been but for Section 2(a)(iii)) required to be
settled by delivery to such party on or prior to such Early Termination Date and
which has not been so settled as at such Early Termination Date, an amount equal
to the fair market value of that which was (or would have been) required to be
delivered as of the originally scheduled date for delivery, in each case
together with (to the extent permitted under applicable law) interest, in the
currency of such amounts, from (and including) the date such amounts or
obligations  were or would have been required to have been paid or performed to
(but excluding) such Early Termination Date, at the Applicable Rate.  Such
amounts of interest will be calculated on the basis of daily compounding and the
actual number of days elapsed.  The fair market value of any obligation referred
to in clause (b) above shall be reasonably determined



                                       13
<PAGE>
 
by the party obliged to make the determination under Section 6(e) or, if each
party is so obliged, it shall be the average of the fair market values
reasonably determined by both parties.

                all payments under this Agreement shall be made without set-off
                or counterclaim and will not be subject to any conditions except
                as provided in Section 2 of this Agreement and except as
                provided in this Section 6 (f). Any amount (the `Early
                Termination Amount') payable to one party (the 'Payee') by the
                other party (the 'Payer') under Section 6(e), in circumstances
                where there is a Defaulting Party or one Affected Party in the
                case where a Termination Event under Section 5(b) has occurred,
                will, at the option of the party ('X') other than the Defaulting
                Party or the Affected Party (and without prior notice to the
                Defaulting Party or the Affected Party), be reduced by its set-
                off against any amount(s) (the 'Other Agreement Amount') payable
                (whether at such time or in the future or upon the occurrence of
                a contingency) by the Payee to the Payer (irrespective of the
                currency, place of payment or booking office of the obligation)
                under any other agreement(s) between the Payee and the Payer or
                instrument(s) or undertaking(s) issued or executed by one party
                to, or in favor of, the other party (and the Other Agreement
                Amount will be discharged promptly and in all respects to the
                extent it is so set-off). X will give notice to the other party
                of any set-off effected under this Section 6(f).

                "For this purpose, either the Early Termination Amount or the
                Other Agreement Amount (or the relevant portion of such amounts)
                may be converted by X into the currency in which the other is
                denominated at the rate of exchange at which such party would be
                able, acting in a reasonable manner and in good faith, to
                purchase the relevant amount of such currency.

                "If an obligation is unascertained, X may in good faith estimate
                that obligation and set-off in respect of the estimate, subject
                to the relevant party accounting to the other when the
                obligation is ascertained.

                "Nothing in this Section 6(f) shall be effective to create a
                charge or other security interest. This Section 6(f) shall be
                without prejudice and in addition to any right of set-off,
                combination of accounts, lien or other right to which any party
                is at any time otherwise entitled (whether by operation of law,
                contract or otherwise),"

(f)       Consent to Recording.  Each Party (i) consents to the recording of the
          telephone conversations of trading and marketing personnel of the
          Parties and their Affiliates in connection with this Agreement or any
          potential Transaction and (ii) agrees to obtain any necessary consent
          of, and give notice of such recording to, such personnel of it and its

          Support Document, and in any Conformation; (iii) the other party
          hereto or thereto has not given to it (directly or indirectly through

            Assets or the business conducted with such Acquired Assets by the
            Sellers, taken as a whole (a "Materially Adverse Effect"), neither
            the execution and delivery of this Agreement by either Seller nor
            the consummation by each Seller of the transactions contemplated
            hereby will constitute a violation of, or be in conflict with, or
            constitute or create a default under, or result in the creation or
            imposition of any Encumbrance upon any of the Acquired Assets
            pursuant to (a) the Certificate of Incorporation or By-Laws of
            either Seller, each as amended to date, (b) any agreement or
            commitment to which either Seller is a party or by which either
            Seller or any of its Acquired Assets is bound or to which either
            Seller or any of such properties is subject, or (c) any statute or
            any judgment, decree, order, regulation or rule of any court or
            governmental authority.

            it shall relabel all unsold Cardiac Assist Division Inventories and
            Inventories supplied to Buyer pursuant to the Interim Supply
            Agreement (which are labeled with the names "Mansfield" or "Boston

            agrees that it shall be responsible for assuring that such new
            labels comply with applicable FDA and other requirements.

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

            product complaints relating to Cardiac Assist Division products
            manufactured by BSC prior to the Closing or after the Closing
            pursuant to the Interim Supply Agreement.

     9.5.   Maintenance of Insurance.  BSC and the Buyer shall each maintain the

            insurance coverage described in Sections 7.8 and 8.10 hereof,
            respectively, (or similar coverage reasonably satisfactory to the
            other) in full force and effect for five (5) years following the
            Closing Date.

     9.6.   Removal of Assets.  Subject to the terms of the Interim Supply

            Boulevard in Mansfield, Massachusetts in order to remove the
            Acquired Assets; provided that all such assets must be removed from
            BSC's premises on or prior to May 1, 1998. BSC acknowledges that
            nothing in the lease agreement covering 135 Forbes Boulevard in
            Mansfield, Massachusetts bars or otherwise prohibits the removal of
            the Acquired Assets.

     9.7.   No Solicitation.  Except with respect to those BSC employees
            ---------------                                             
            dedicated exclusively to the Cardiac Assist Division, the Buyer
            shall not, without the prior written consent of BSC, solicit or hire
            any BSC employees to work for the Buyer, or its affiliates, for one
            (1) year after the Closing Date, except that the Buyer may hire a
            BSC employee who responds to a bona fide general solicitation for
            employment not directed toward one or more BSC employees.

     9.8.   Employment Matters.  The Buyer has agreed to employ those employees
            ------------------

            effective as of such time as the parties may mutually agree, subject

            without limitation, any unpaid pension liabilities) earned by such
            employees prior to such date and the Buyer shall be responsible for
            such compensation and other benefits earned on and following such
            date. BSC shall be
<PAGE>
 
            solely responsible for all compensation and other benefits
            (including, without limitation, any unpaid pension liabilities)
            earned, or to be earned, by, and (except as provided in the Interim
            Supply Agreements) all other liabilities relating to the employment
            of, all other employees of BSC's Cardiac Assist Division prior, and
            subsequent, to the Closing Date.

     9.9.   Non-Competition.  Except as otherwise provided in the Interim Supply
            ---------------                                                     
            Agreement, the Sellers agree, and shall cause their subsidiaries to
            agree, not to manufacture or sell intraaortic balloon catheters and
            pumps which are competitive with those manufactured or sold by BSC's
            Cardiac Assist Division as of the Closing Date ("Competitive
            Products") for a period of two (2) years following the Closing Date.
            Notwithstanding the foregoing, BSC may acquire businesses which,
            among other things, manufacture or sell Competitive Products
            ("Competitive Businesses") so long as less than forty percent (40%)
            of any such Competitive Business' revenues (measured as of the most
            recent fiscal year-end of the Competitive Business) are derived from
            sales of Competitive Products.

     9.10.  Distribution Contracts.  On or promptly after the Closing Date, BSC
            ----------------------                                             
            shall send letters seeking the termination of each of the
            Distribution Contracts listed on Schedule 9.10. BSC shall send
            letters terminating such contracts, or where applicable giving
            notice of termination, as promptly as practicable and shall, upon
            Buyer's request, provide copies of all such letters to Buyer.

            or the Buyer, respectively (an "Indemnifying Party"), under this
            Section 10 in connection with any action, suit, proceeding or demand
            at any time instituted against or made upon an Indemnified Party for
            which such Indemnified Party may seek indemnification hereunder (a
            "Claim"), such Indemnified Party shall notify promptly the proper
            Indemnifying Parties of such Claim and of such Indemnified Party's

            such Indemnifying Party shall not have the authority to negotiate,
            compromise and settle such Claim without the prior written consent

            hereto, but such Indemnified Party shall bear and shall be solely

     names or titles at any time.  From and after the Closing Date, the Buyer
     and/or its nominee(s) may use the trade names of BSC, other than
     "Mansfield" and "Boston Scientific", only to the extent that such names
     relate solely to the Cardiac Assist Division of BSC, and BSC agrees that
     from and after the Closing Date BSC will discontinue its use of all such
     names, except as contemplated under the Interim Supply Agreement.

            hereto contained in this Agreement or otherwise made in writing in
            connection with the transactions contemplated hereby shall survive

            given notice of an indemnifiable claim relating to such
            representations, warranties, covenants or agreements to any Seller

            Seller to indemnification with respect to that liability shall

            disposed of, and provided, further, that the foregoing one (1) year
            limitation shall not apply in instances of fraud. Notwithstanding
            the foregoing, the consummation of the Closing shall not terminate

            deliver such further instruments of conveyance and transfer and take
            such other actions as the Buyer may reasonably require to more
            effectively convey and transfer any of the Acquired Assets to the
            Buyer. The Sellers and the Buyer shall also execute and deliver to
            the appropriate other party such other instruments as may be
            reasonably required in connection with the performance of this
            Agreement and each shall take all such further actions as may be

and privilege to use (and to grant sublicenses to others to use) the License
Rights in the License Field including the right to make and manufacture, have
made and manufactured, use, sell, distribute and otherwise dispose of the

     It is contemplated that Licensor and Licensee may, from time to time in the

information including technical information, and other know how, techniques and
processes, and trade secrets. To the extent it is deemed confidential, all such
information, know-how, techniques, processes and trade secrets shall remain
proprietary to Licensor and Licensee, as the case may be. Licensor and Licensee
mutually agree to keep such information in confidence to the same degree and
with the same protection by which they maintain their own proprietary
information confidential for five (5) years following the date hereof. Licensee,
subject to the above confidentiality requirements, and to the extent such
information relates directly to the License Field, may use such information
royalty-free during the term of this Agreement for any purpose in the

through no breach of the receiving party; (ii) the receiving party can show, by
its written records, that the information was already in its possession at the
time of disclosure by the other party; (iii) the receiving party can show by its

that it acquired the information from a third party who had the legal right to
disclose it.

The termination of this Agreement shall not relieve Licensor or Licensee from

                          EXCLUSIVE LICENSE AGREEMENT
                          ---------------------------

     THIS AGREEMENT (the "Agreement") is made this 14th day of February, 1996
                                                   ----                      
by and between ISRAEL SCHUR, M.D., an individual residing at Ten Amsterdam
Avenue, Apartment 309, New York, New York 10023 ("Licensor")

                                      and

ARROW INTERNATIONAL, INC., a Pennsylvania corporation having its principal
office located at 3000 Bernville Road, Reading, Berks County, Pennsylvania 19605
("Licensee").

                                   BACKGROUND

    Licensor has developed a concept for an unscrewing hub luer for radial
artery catheters and other types of over-the-needle catheters (the "Product").
Licensor has filed an application for a patent for said concept and subsequently
filed a continuation-in-part application (collectively, together with any future
application or amendment, the "Patent Application") which is now pending in the
United States Patent and Trademark Office (the "Patent Office").  Licensor has
also filed a patent application pertaining to the Product pursuant to the Patent
Cooperation Treaty (the "PCT Application").  Licensor desires Licensee to
develop and produce prototypes of the Product and to test market the Product,
and Licensee is willing to undertake such prototype development and test
marketing under the terms and conditions set forth in this Agreement.

     NOW, THEREFORE, in consideration of the above premises and mutual covenants
and conditions herein contained, and INTENDING TO BE LEGALLY BOUND HEREBY, the
parties hereto agree as follows:
<PAGE>
 
     1.  Background.  The parties hereto acknowledge the accuracy of the
         ----------                                                     
statements hereinabove set forth in the Background, and said Background is
incorporated into this Agreement by reference thereto.

     2.  Licensor's Representations.  Licensor represents to Licensee that he
         --------------------------                                          
has developed an idea and concept for the Product, and has filed the Patent
Application and the PCT Application which are presently pending in the Patent
Office.  Attached hereto, marked Exhibits "A" and "B" respectively and
incorporated herein by reference thereto are true and correct copies of the
Patent Application and the PCT Application filed by Licensor and presently
pending in the Patent Office.

     3.  Grant of License.  Licensor hereby grants, and Licensee hereby accepts,
         ----------------                                                       
upon the terms and conditions herein set forth, the right (i) to use world-wide
Licensor's Know-How (hereinafter defined), (ii) a world-wide exclusive license
to make, have made, use, sell and put into use the Product and any other product
developed by Licensor that is similar to the Product, and (iii) a world-wide
exclusive license to make use of any and all U.S. and foreign patents issued to
Licensor pertaining in any manner to the Product or any other product similar to
the Product, and any know-how related to the Product or any similar product.

     4.  Reimbursement of Certain Expenses.  Licensee agrees, within thirty (30)
         ---------------------------------                                      
days after both of (i) the execution and delivery of this Agreement by the
parties hereto and (ii) the delivery to Licensee of Licensor's Know-How, to
reimburse Licensor for Licensor's reasonable expenses, documented to Licensee's
reasonable satisfaction, incurred to date pertaining to the preparation and
filing of the Patent Application and the PCT Application; provided, however,
that the aggregate amount of such reimbursement by Licensee to Licensor shall
not exceed the maximum sum of

                                       2
<PAGE>
 
$20,000.00, and provided further such reimbursement shall be made by Licensee to
Licensor no later than sixty (60) days after the execution of this Agreement if
Licensee has not requested Licensor's Know-How pursuant to Paragraph 6 below by
such date.  In addition, Licensee shall be responsible for all expenses incurred
subsequent to the date of this Agreement pertaining to the Patent Application
and the PCT Application.  Licensee, in its sole discretion, shall also have the
right to file patent applications in any country in the world other than the
United States on Licensor's behalf and Licensee shall be responsible for all
reasonable expenses incurred in any such filing, the approximate amount of which
shall be subject to Licensee's pre-approval.  Any such filing shall, in
Licensor's discretion, be made by an attorney selected by Licensor.  In any
event, Licensor shall cooperate with Licensee in the preparation and/or any
execution of any documents, including patent applications which, in the opinion
of counsel, is necessary to file such patent application.

     5.   Prototypes.  Licensee agrees that following the execution and delivery
          ----------                                                            
of this Agreement, Licensee will use its best efforts to develop the tooling for
the production of a sufficient number of prototypes of the Product (the
"Prototypes") to enable Licensee to conduct a wide-spread field/market
evaluation (the "Evaluation") of the Product.  Licensee shall have a period of
six (6) months after the execution and delivery of this Agreement to develop and
manufacture the Prototypes, and thereafter Licensee shall have an additional
period of three (3) months to conduct the Evaluation, all of which shall be at
the sole expense of Licensee; provided, however, if all FDA required approvals
are not received by Licensor or Licensee within the aforesaid six (6) month
period, then the time that Licensee shall have to conduct the Evaluation shall
be extended for such period of



                                       3
<PAGE>
 
time as may be necessary for Licensee to have a period of time of three (3)
months following the receipt of such FDA approvals, to conduct the Evaluation.

     6.  Licensor's Know-How.  At such time as Licensee shall request, Licensor
         -------------------                                                   
shall deliver to Licensee all of Licensor's trade secrets, technical know-how
and other knowledge, information, instructions and engineering advice
("Licensor's Know-How") relating to the Patent Application and the Product to
assist Licensee in the development of the tooling necessary to produce the
Prototypes (as well as a commercial version of the Product if Licensee decides
to produce and market the Product pursuant to Paragraph 8 below); and Licensor's
Know-How shall be received and maintained in strict confidence by Licensee and
shall not be disclosed by Licensee without the prior written permission of
Licensor; provided, however, that Licensee shall be permitted to disclose
Licensor's Know-How to a third party who is engaged by Licensee to make the
Product for Licensee so long as said third party shall agree in writing to be
bound by the provisions of this Paragraph.

     7.   Licensee's Right to Withdraw.  In the event that Licensee concludes,
          ----------------------------                                        
after producing such Prototypes and conducting the Evaluation of the Product
(or, after reasonable efforts, concludes that such Prototypes can not be
produced), that the Product can not perform its intended function or use, or in
the event that Licensee or Licensor shall receive notice of a claim that any
patent issued pursuant to the Patent Application infringes upon a patent issued
to a third party, then in any such event Licensee may notify Licensor to such
effect; and upon such notice being given, this Agreement shall automatically
terminate, and thereafter neither the Licensor nor the Licensee shall have any
further rights, obligations, liabilities or responsibilities under this
Agreement and neither shall have any further claims against or liabilities to
the other.

                                       4

     8.  Royalties.  In the event Licensee proceeds to manufacture the Product
         ---------                                                            
for commercial purposes, then so long as this Agreement is in effect Licensee
shall pay to Licensor royalties ("Royalty" or "Royalties") on the following
basis:
         (a) A Royalty of $0.025 per Product unit used with each existing type
of product currently manufactured by Licensee or any variation thereof or any
such product that may hereafter be changed or modified, on which Licensee
incorporates the Licensor's Product ("Licensee's Existing Product Unit"), said
existing products to include, without limitation, existing radial artery
catheters and existing spring-wire introducer catheters, as any such catheter
may hereafter be changed or modified; and $0.05 per Product unit used with (i)
new (i.e. not currently manufactured and excluding any subsequent change,
modification or variation of an existing product currently being manufactured by
Licensee) radial artery catheters not containing a spring-wire guide, or (ii)
other new (i.e. not currently manufactured and excluding any subsequent change,
modification or variation of an existing product currently being manufactured by
Licensee) "stand-alone" over-the-needle catheter devices ("Licensee's Other Use
Unit"); ("Licensee's Other Use Units" and "Licensee's Existing Product Units"
hereinafter collectively the "Units"), concerning which the Product has been
incorporated.

         (b) Royalties hereinabove provided for shall become payable
commencing with the first commercial sale for which a Royalty is due to Licensor
pursuant to the within Paragraph 8.

         (c) Licensee agrees to pay Licensor minimum Royalties on an annual
basis (the first such year to commence on the earlier of (i) the date occurring
six (6) months after the expiration of the applicable (3) three month period to
conduct the Evaluation referred to in Paragraph 5 above, or (ii) the date of
Licensee's first commercial sale of any of its products incorporating the
Product

                                       5
<PAGE>
 
for which a Royalty is provided for in subparagraph (a) of this Paragraph, and
continue until the first anniversary of such date; and each subsequent year to
be calculated from any anniversary date to the immediately following anniversary
date).  Following the date that Royalties shall first become payable, the
minimum annual Royalties to be paid to Licensor shall be as follows:

               (1) for the first year for which Royalties are to be paid, the
minimum sum of $25,000.00;

               (2) for the second year for which Royalties are to be paid, the
minimum sum of $37,500.00; ;

               (3) for the third year for which Royalties are to be paid, the
minimum sum of $50,000.00; and

               (4) for the fourth year and for each year thereafter that this
Agreement is in effect, $50,000.00.

The aforesaid minimum annual Royalties shall be paid by Licensee to Licensor
whether or not such quantity or quantities of the products incorporating the
Product are manufactured and/or sold by Licensee during the appropriate annual
period, which, when multiplied by the applicable Royalty or Royalties provided
for in Paragraph 10(a) above, results in such minimum annual Royalties.  In the
event this Agreement is in effect for only a portion of any such annual period,
then the minimum Royalties to be paid for such annual period shall be
apportioned on a per diem basis, or pro rata basis.

         (d) Notwithstanding the aforesaid, in the event that Licensee or
Licensor shall receive notice of a claim that any patent issued pursuant to the
Patent Application infringes upon a

                                       6
<PAGE>
 
patent issued to a third party, then the annual minimum Royalties hereinabove
provided for shall be fifty percent (50%) of the amount thereof until such time
as it is established to Licensee's satisfaction that any such infringement no
longer exists

         (e) At the conclusion of the first year for which Royalties are to be
paid, and at the conclusion of each such year thereafter, the amount of each
Royalty to be paid by Licensee to Licensor pursuant to Subparagraph (a) above
shall be adjusted by applying fluctuations in the Consumer Price Index to the
amount of each Royalty as follows: (i) the Consumer Price Index for the purposes
of this Agreement shall be the Consumer Price Index for All Urban Consumers
(CPI-U) published by the Bureau of Labor Statistics of the United States
Department of Labor for the United States.  If the Consumer Price Index ceases
to be published by the United States Department of Labor, Bureau of Labor
Statistics, then the calculations shall be based on the closest successor index
as identified by the United States Department of Labor.  If no such successor
index exists, then the calculation shall be based on an index as mutually agreed
to by the Licensor and Licensee; (ii) the base date shall be the calendar month
preceding the date of the commencement of the first yearly period for which
Royalties are payable by the Licensee to Licensor; (iii) commencing with the
second year for which Royalties are payable, the adjusted amount of each Royalty
shall be determined by multiplying the amount of such Royalty for the immediate
preceding year by a fraction, the numerator of which shall be the Consumer Price
Index hereinabove referred to for the last month of the immediately preceding
year during which such Royalty was payable, and the denominator of which shall
be the Consumer Price Index for the base date.  The resulting sum, if greater
than the amount of each Royalty set forth in Subparagraph (a) above, shall be
the amount of the adjusted Royalty.

                                       7
<PAGE>
 
         (f) If no patent has been issued to Licensor pursuant to the Patent
Application by the time Licensee is ready to market the Product on a commercial
basis, then for the first five (5) years that this Agreement is in effect (or
until such time as such a patent shall issue within the aforesaid five (5) year
time period), the annual minimum Royalties hereinabove provided for shall be
fifty percent (50%) of the amount thereof.

         (g) Within ninety (90) days after the date this Agreement is
terminated, Licensee shall provide Licensor with a final accounting of the
Product made and sold through the effective date of termination and pay
Royalties to Licensor then due hereunder.

     9.  Payment of Royalties.  So long as this Agreement is in effect, the
         --------------------                                              
royalties to be paid by Licensee to Licensor shall be paid in accordance with
the following terms and conditions:
         
         (a) Royalties payable to Licensor pursuant to Paragraph 8 above shall
be paid quarterly within thirty (30) days following the end of each calendar
quarter.  Licensee shall compute each payment showing in reasonable detail the
computation of the royalty payment.

         (b) Licensee shall keep and maintain accurate and complete books and
records relating to all matters affecting the Royalties payable hereunder.
Licensor shall have the right, at reasonable times and on reasonable notice, to
inspect such books at Licensee's offices.  Licensee shall be required to retain
records relating to the Product for which payment of Royalties has been made no
more than three (3) years after payment in accordance with subparagraph (a) of
this Paragraph 9 above.  Except as may be required in connection with the
resolution of any dispute arising out of this Agreement, Licensor shall keep in
confidence all information furnished to it, either in the form of a statement of
Royalties delivered by Licensee or any information which it might gain or gather
from

                                       8
<PAGE>
 
the inspection of Licensee's books, except as must be disclosed by Licensor in
compliance with applicable law or regulation.  If any inspection discloses any
error, the parties shall by appropriate payment forthwith adjust the same.

     10. Improvements.
         ------------ 
     
         (a) Licensee may, in such manner as it deems fit at its sole cost and
expense, modify, alter, change or improve (the "Improvement") any part of the
Product and use any Improvement by itself or in combination with any other
product component or assembly of components; provided, however, that any such
Improvement shall not excuse Licensee from its obligations to pay Royalties
hereunder.  Any such Improvement shall remain the sole property of the Licensee,
and Licensee reserves the right to apply for patent protection with respect
thereto; provided, however, that in the event Licensee advises Licensor in
writing that Licensee has elected not to apply for such patent protection, then
Licensor shall have the right to apply for such patent protection in his own
name and at his own cost, in which event Licensee shall have a non-exclusive
royalty-free license in accordance with the terms of this Agreement under any
such patent.  Licensor shall cooperate with Licensee in the preparation and/or
execution of any documents, including patent applications, which, in the opinion
of counsel for Licensee, is necessary to protect Licensee's interest in any
Improvement.
         
         (b) Licensee agrees that, so long as this Agreement is then in effect,
Licensee will, within one (1) year after it commercially markets a product
incorporating the Product, develop and market a radial artery catheter, usable
for arterial and intravenous applications, without a wire guide that
incorporates the Product.  If Licensee elects not to market such a product as
aforesaid, then, in

                                       9
<PAGE>
 
such event, Licensee's license provided for in Paragraph 3 above shall no longer
apply to a radial artery catheter usable for arterial and intravenous
applications, and Licensor shall have the right to license another party for the
sole purpose of developing and marketing such a product (i.e., a radial artery
catheter usable for arterial and intravenous applications), without further
obligation or liability on the part of Licensee.

     11. Term.  Unless sooner terminated as provided for in Paragraph 7 above
         ----                                                                
or in Paragraph 12 below, this Agreement shall remain in effect for a period of
time that shall commence on the date hereof and end on the date that any patent
issued pursuant to the Patent Application shall expire, and thereafter shall no
longer be in effect, shall terminate and become null and void.

     12. Termination.
         ----------- 
        
         (a) Lack of FDA Approval.  Notwithstanding the provisions of Paragraph
             --------------------                                              
11 above, this Agreement shall automatically terminate on the date FDA denies
such approval, if any, as may be necessary to market the Product commercially

         (b) Termination by Licensor.  In addition to any other right of 
             ----------------------- 
termination provided for in this Agreement, in the event Licensee does not
commercially market the licensed Product within one (1) year after FDA approval,
or after having commercially marketed, ceases to commercially market the Product
for a continuous period of two (2) years during the term of this Agreement,
Licensor may terminate this Agreement at any time upon giving at least thirty
(30) days prior written notice of such termination to Licensee.

         (c) Termination by Licensee.  In addition to any other right of 
             -----------------------                                    
termination provided for in this Agreement, at any time after the first
anniversary date of this Agreement,


                                       10
<PAGE>
 
Licensee, in its sole discretion and/or determination, shall have the right to
terminate this Agreement upon giving the Licensor not less than three (3) months
prior written notice.  In addition, Licensee shall have the right to terminate
this Agreement if any action is instituted against Licensee claiming
infringement of a third party patent and Licensor does not defend Licensee in
such action.

         (d) Termination for Breach.  If either party shall materially breach
             ----------------------                                          
or default under this Agreement, the other party may give written notice of its
intention to terminate this Agreement, stating in reasonable detail the nature
of the breach or default.  Subject to clause (f) below, if the party in breach
or default fails to cure or remedy its breach or default within thirty (30)
days, the other party may, while such breach or default continues, terminate
this Agreement forthwith upon prior written notice of such termination to the
other party.

         (e) Reversion of Rights.  Upon any termination pursuant to the within
             -------------------                                              
Paragraph 12 or Paragraph 7 above, except a termination caused by Licensor's
breach, all rights of Licensee under this Agreement shall terminate and
thereafter Licensee shall not have any right to manufacture the Product or to
use any of Licensor's Know-How or to disclose any such information to any third
party.

         (f) Limitation of Remedies.  In the event Licensee shall fail for any
             ----------------------                                           
calendar year to pay to Licensor the minimum Royalties provided for in Paragraph
8(c) above, then Licensor's sole remedy shall be (i) to terminate this Agreement
upon giving Licensee fifteen (15) days prior written notice of such termination
and said minimum Royalties are not paid within said fifteen (15) day time
period, and (ii) to seek to recover from Licensee an amount which together with
such Royalties



                                       11
<PAGE>
 
received by Licensor for the calendar year in question, will equal the minimum
Royalties to which Licensor would be entitled to pursuant to Paragraph 8 above.

     13. Relationship.  Nothing contained in this Agreement shall be construed
         ------------                                                         
by the parties hereto or by any third party as constituting the parties as
principal and agent, partners or joint ventures, nor shall anything herein
(except as otherwise specifically provided) render either party liable for the
debts and obligations of the other, it being understood and agreed that the only
relationship between the parties hereto is that of Licensor and Licensee.

     14. Assignment.  Except as hereinafter provided, this Agreement shall not
         ----------                                                           
be assignable by either party without the prior written approval of the other
party.  Notwithstanding the aforesaid, (i) Licensee shall have the right to
assign its interest in this Agreement to any parent corporation, subsidiary or
affiliate of Licensee, although in such instance Licensee shall not be relieved
of its obligation to pay minimum Royalties as hereinabove provided, and (ii)
Licensor shall have the right to assign his interest, or any portion thereof, in
this Agreement and the Royalties payable to Licensor hereunder to any member of
his immediate family (which, for the purposes of this provision, shall be
limited to spouse, children and/or grandchildren, parents, brothers and/or
sisters of Licensor) so long as Licensor retains his ownership of any patent
issued pursuant to the Patent Application and/or the PCT Application or a pro
rata interest therein is assigned by Licensor to the member of the Licensor's
immediate family to whom an interest in this Agreement and the Royalties is
assigned.  To the extent assignable, this Agreement shall be binding upon and
shall inure to the benefit of the parties hereto, their heirs, executors,
administrators, successors and assigns.

     15. Infringement.
         ------------ 

                                       12
<PAGE>
 
         (a) Infringement by Third Parties.  In the event that any patent
             -----------------------------                               
issued pursuant to the Patent Application, the PCT Application and/or any other
foreign application shall be infringed or appear to be infringed by a third
party so as to subject the Licensee to substantial unlicensed competition, the
parties agree to cooperate in efforts to abate the infringement or otherwise
settle the matter.  Licensor shall have the first right, but not the obligation,
to notify the infringer and/or to initiate litigation or legal proceedings to
abate the infringement.  Licensee may elect to join in any such legal
proceedings.  In the event Licensor does not initiate such legal proceedings
within four (4) months after becoming aware of the infringement, then Licensee
may initiate such infringement proceedings on its own behalf and thereafter
Licensor may elect to join in those proceedings.  Any recovery of proceeds from
settlement shall be shared between Licensor and Licensee in proportion to the
expenses of the proceedings borne by each party.

         (b) Third Party Patents.  To the best of Licensor's present knowledge,
             -------------------                                               
information and belief, no adversely owned patent will be infringed by
Licensee's activities pursuant to this Agreement.  In the event Licensee's
activities pursuant to this Agreement result in an action for infringement
against Licensee, based on an adversely owned patent, Licensor shall have the
right to defend Licensee in any such action at Licensor's sole cost and expense.
Licensee may elect to join in any such action at its own expense and may
undertake the defense of any such action if Licensor does not elect to defend
Licensee.  Licensee may defer payment of Royalties due under Paragraph 8 above
to the extent of Licensee's legal expenses as concerns any such action until
either the withdrawal of the claim of infringement or the termination of such
action with the determination that Licensee's activities do not infringe upon
such third party's patent.

CAUTIONARY STATEMENT FOR PURPOSES OF THE SAFE HARBOR PROVISIONS OF THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995

     From time to time, in both written reports and in oral statements by our
senior management, expectations and other statements are expressed regarding our
future performance.  These forward-looking statements are inherently uncertain
and investors must recognize that events could turn out to be different than
such expectations and statements.  Key factors impacting our current and future
performance are discussed in our Annual Report on Form 10-K with which this
Exhibit is filed and other filings with the Securities and Exchange Commission
(the "Commission").  In addition to such information in our Annual Report on
Form 10-K and our other filings with the Commission, investors should consider
the following risk factors in evaluating us and our business, as well as in
reviewing forward-looking statements contained in our periodic reports filed
with the Commission and in oral statements made by our senior management.  Our
actual results could differ materially from such forward-looking statements due
to material risks, uncertainties and contingencies, including, without
limitation, those set forth below.

STRINGENT GOVERNMENT REGULATION

     Our products are subject to extensive regulation by the Food and Drug
Administration (the "FDA") and, in some jurisdictions, by state, local and
foreign governmental authorities.  In particular, we must obtain specific
clearance or approval from the FDA before we can market new products or certain
modified products in the United States.  With the exception of one product, we
have, to date, obtained FDA marketing clearance for our products only through
the 510(k) premarket notification process.  Certain of our products under
development and future applications, however, will require approval through the
more vigorous Premarket Approval application ("PMA") process.  The process of
obtaining such clearances or approvals can be time consuming and expensive.  We
cannot assure that the FDA will grant all clearances or approvals sought by us
or that FDA review will not involve delays adversely affecting the marketing and
sale of our products.  We are also required to adhere to applicable regulations
setting forth current Good Manufacturing Practices ("GMP") which require that we
manufacture our products and maintain our records in a prescribed manner with
respect to manufacturing, testing and control activities.  In addition, we are
required to comply with FDA requirements for labeling and promotion of our
products.  Failure to comply with applicable federal, state, local or foreign
laws or regulations could subject us to enforcement action, including product
seizures, recalls, withdrawal of clearances or approvals, and civil and criminal
penalties, any one or more of which could have a material adverse effect on our
business, financial condition and results of operations.  Many of the foreign
countries where we conduct business have adopted medical device laws and
regulations with similar substantive and enforcement provisions.  Federal,
state, local and foreign laws and regulations regarding the development,
manufacture and sale of medical devices are subject to future changes.  We
cannot assure that such changes will not have a material adverse effect on our
business, financial condition and results of operations.

SIGNIFICANT COMPETITION AND CONTINUAL TECHNOLOGICAL CHANGE

     The markets for medical devices are highly competitive.  We currently
compete with many companies in the development and marketing of catheters and
related medical devices.  Some of our competitors have access to greater
financial and other resources than us.

                                     (70)
<PAGE>
 
     Furthermore, the markets for medical devices are characterized by rapid
product development and technological change.  Technological advances by one or
more of our current or future competitors could render our present or future
products obsolete or uneconomical.  Our future success will depend upon our
ability to develop new products and technology to remain competitive with other
developers of catheters and related medical devices. Our business strategy
emphasizes the continued development and commercialization of new products and
the enhancement of existing products for the critical care and interventional
procedure markets.  We cannot assure that we will be able to continue to
successfully develop new products and to enhance existing products, to
manufacture these products in a commercially viable manner, to obtain required
regulatory approvals or to gain satisfactory market acceptance for our products.

COST PRESSURES ON MEDICAL TECHNOLOGY AND PROPOSED HEALTH CARE REFORM

     Our products are purchased principally by hospitals, hospital networks and
hospital buying groups.  Although our products are used primarily for non-
optional medical procedures, we believe that the overall escalating cost of
medical products and services has led and will continue to lead to increased
pressures upon the health care industry to reduce the cost or usage of certain
products and services.  In the United States, these cost pressures are leading
to increased emphasis on the price and cost-effectiveness of any treatment
regimen and medical device.  In addition, third party payors, such as
governmental programs, private insurance plans and managed care plans, which are
billed by hospitals for such health care services, are increasingly negotiating
the prices charged for medical products and services and may deny reimbursement
if they determine that a device was not used in accordance with cost-effective
treatment methods as determined by the payor, was experimental, unnecessary or
used for an unapproved indication.  In international markets, reimbursement
systems vary significantly by country.  Many international markets have
government managed health care systems that control reimbursement for certain
medical devices and procedures and, in most such markets, there also are private
insurance systems which impose similar cost restraints. We cannot assure that
hospital purchasing decisions or government or private third party reimbursement
policies in the United States or in international markets will not adversely
affect the profitability of our products.

     In recent years, several comprehensive health care reform proposals have
been introduced in the U.S. Congress.  While none of these proposals have to
date been adopted, the intent of these proposals was, generally, to expand
health care coverage for the uninsured and reduce the rate of growth of total
health care expenditures.  In addition, certain states have made significant
changes to their Medicaid programs and have adopted various measures to expand
coverage and limit costs.  Implementation of government health care reform and
other efforts to control costs may limit the price of, or the level at which
reimbursement is provided for, our products.  Several foreign countries have
recently considered, and in some countries adopted, similar reforms to limit the
growth of health care costs, including price regulation.  We anticipate that
Congress, state legislatures, foreign governments and the private sector will
continue to review and assess alternative health care delivery and payment
systems.  We cannot predict what additional legislation or regulation, if any,
relating to the health care industry may be enacted in the future or what impact
the adoption of any federal, state or foreign health care reform, private sector
reform or market forces may have on our business.  We cannot assure that any
such reforms will not have a material adverse effect on the medical device
industry in general, or on our business, in particular.

                                     (71)

DEPENDENCE ON PATENTS AND PROPRIETARY RIGHTS

     We own numerous U.S. and foreign patents and have several U.S. and foreign
patent applications pending.  We also have exclusive license rights to certain
patents held by third parties.  These patents relate to aspects of the
technology used in certain of our products.  From time to time, we are subject
to legal actions involving patent and other intellectual property claims.
Successful litigation against us regarding our patents or infringement of the
patent rights of others could have a material adverse effect on our business,
financial condition and results of operations.  In addition, we cannot assure
that pending patent applications will result in issued patents or that patents
issued to or licensed-in by us will not be challenged or circumvented by
competitors or found to be valid or sufficiently broad to protect our technology
or to provide it with any competitive advantage.  We also rely on trade secrets
and proprietary technology that we seek to protect, in part, through
confidentiality agreements with employees, consultants and other parties.  We
cannot assure that these agreements will not be breached, that we will have
adequate remedies for any breach, that others will not independently develop
substantially equivalent proprietary information or that third parties will not
otherwise gain access to our trade secrets.

     There has been substantial litigation regarding patent and other
intellectual property rights in the medical devices industry.  Historically,
litigation has been necessary to enforce certain patent and trademark rights
held by us.  Future litigation may be necessary to enforce patent and other
intellectual property rights belonging to us, to protect our trade secrets or
other know-how owned by us, or to defend ourself against claimed infringement of
the rights of others and to determine the scope and validity of our and others'
proprietary rights.  Any such litigation could result in substantial cost to and
diversion of effort by us.  Adverse determinations in any such litigation could
subject us to significant liabilities to third parties, require us to seek
licenses from third parties and prevent us from manufacturing, selling or using
certain of our products, any one or more of which could have a material adverse
effect on our business, financial condition and results of operations.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

     We generate significant sales outside the United States and are subject to
risks generally associated with international operations, such as unexpected
changes in regulatory requirements, tariffs, customs, duties and other trade
barriers, difficulties in staffing and managing foreign operations, longer
payment cycles, problems in collecting accounts receivable, political risks,
fluctuations in currency exchange rates, foreign exchange controls which
restrict or prohibit repatriation of funds, technology export and import
restrictions or prohibitions, delays from customs brokers or government agencies
and potentially adverse tax consequences resulting from operating in multiple
jurisdictions with different tax laws, any one or more of which could materially
adversely impact the success of our international operations.  As our revenues
from international operations increase, an increasing portion of our revenues
and expenses will be denominated in currencies other than U.S. dollars and,
consequently, changes in exchange rates could have a greater effect on our
future operations.  We cannot assure that such factors will not have a material
adverse effect on our business, financial condition and results of operations.
In addition, we cannot assure that laws or administrative practices relating to
regulation of medical devices, taxation, foreign exchange or other matters of
countries within which we operate will not change.  Any such change could also
have a material adverse effect on our business, financial condition and results
of operations.

                                     (72)
<PAGE>
 
POTENTIAL PRODUCT LIABILITY

     Our business exposes us to potential product liability risks which are
inherent in the testing and marketing of catheters and related medical devices.
Our products are often used in intensive care settings with seriously ill
patients.  In addition, many of the medical devices manufactured and sold by us
are designed to be implanted in the human body for long periods of time and
component failures, manufacturing flaws, design defects or inadequate disclosure
of product-related risks with respect to these or other products manufactured or
sold by us could result in an unsafe condition or injury to, or death of, the
patient.  The occurrence of such a problem could result in product liability
claims and/or a recall of, or safety alert relating to, one or more of our
products.  We cannot assure that the product liability insurance maintained by
us will be available or sufficient to satisfy all claims made against us or that
we will be able to obtain insurance in the future at satisfactory rates or in
adequate amounts.  Product liability claims or product recalls in the future,
regardless of their ultimate outcome, could result in costly litigation and
could have a material adverse effect on our business or reputation or on our
ability to attract and retain customers for our products.

RISKS ASSOCIATED WITH DERIVATIVE FINANCIAL INSTRUMENTS

     As a partial hedge against adverse fluctuations in exchange rates, we
periodically enter into foreign currency exchange contracts with certain major
financial institutions.  By their nature, all such contracts involve risk,
including the risk of nonperformance by counterparties.  Accordingly, losses
relating to these contracts could have a material adverse effect upon our
business, financial condition and results of operations.  Our policy prohibits
the use of derivative instruments for speculative purposes.

DEPENDENCE ON KEY MANAGEMENT

     Our success depends upon the continued contributions of key members of our
senior management team, certain of whom have been with us since our inception in
1975.  Accordingly, loss of the services of one or more of these key members of
management could have a material adverse effect on our business.  None of these
individuals has an employment agreement with us.

RISKS ASSOCIATED WITH YEAR 2000

     We are actively addressing the Year 2000 problem as it relates to our
business operations and regulation by the FDA.  The following disclosure
describes our progress toward our objective of ensuring that our business
systems will operate satisfactorily on or after January 1, 2000.

     Our Central Venous Catheters and other catheter products are unaffected by
the Year 2000 problem.  Early in 1998, we responded to the FDA concerning the
effect of the Year 2000 problem on our Intra-Aortic Balloon Pumps (IABPs).  The
software in the more recent models of our IABPs has taken the change of century
issues into account.  The operating range for the clock calendar in these IABPs
spans a 100 year period from the years 1988 through 2087.  The clock calendar on
certain older models advances as high as 1999.  However, none of our IABPs
depend on the year information for any calculations or in communicating with
other electronic devices and will function as intended or expected, regardless
of the date.  We provide our customers requesting certifications with specific
IABP model numbers that have or do not have the updated clock calendars.

     Therefore, our major Year 2000 concerns relate to business systems that
support the continuity of our business operations and the delivery of products
and support services to our customers.

     For business applications relating to sales order processing, billing,
disbursements, marketing and manufacturing management, we have completed the
necessary software code modifications in the development version of the
applications.  During the remainder of 1998, we will test the modified versions
by advancing the date beyond December 31, 1999.  The validated software will
then be moved to our production machines.  We plan to test and validate our U.S.
payroll and general ledger systems in the above manner in the spring of 1999.
We estimate our cost of software upgrades to be approximately $30,000 for all
U.S. systems and $120,000 for foreign systems.  Our internal resources devoted
to these efforts are estimated at 500 man-days.  In the event that our
production systems malfunction due to the change to the year 2000, we plan to
move the affected software and data back to the machines on which validation was
completed so that our business processes can continue.

     We plan to test and make Year 2000 compliant our engineering documentation
systems which are critical for our manufacturing operations by the spring of
1999.

     We upgraded our personal computer systems in fiscal 1998 at a cost of
$700,000.  We estimate spending an additional $500,000 in fiscal 1999 to upgrade
our servers and replace our e-mail system.

     Our computer controlled equipment includes programmable controllers on
production equipment and systems for time and attendance recording, building
management, life safety, security, elevators, air compressors and high purity
water.  For equipment or systems controlled by computer chips or programs, we
plan to contact the manufacturer to determine that these systems or equipment
are Year 2000 compliant.  We expect that these efforts will be completed by the
end of 1998.

     The status of Year 2000 compliance by our key suppliers of products and
services will be determined by using a compliance survey, which we expect to
mail to such suppliers prior to the end of 1998. We plan to contact by telephone
organizations who do not respond to our survey or who report a lack of Year 2000
compliance in their critical business processes.

     We increased our available domestic revolving credit facility to $75
million in October 1998.  This additional borrowing capacity could be utilized
to support our cash flow requirements in the event that health care providers
are unable to pay amounts owed to us on a timely basis due to system
malfunctions related to the Year 2000 change.

     If we are able to fulfill our plans to secure our business systems as
described above, then any adverse Year 2000 effects we may experience will arise
from circumstances outside our control.  Because we cannot reasonably anticipate
such circumstances at this time, we have not developed a Year 2000 worst case
scenario.  While we believe that we are adequately addressing the Year 2000
problem, we cannot assure that the cost and liabilities associated with the Year
2000 problem will not materially adversely impact our business, financial
condition and results of operations.
