ITEM 1.  BUSINESS

COMPANY OVERVIEW
     Kensey Nash Corporation ("the Company") was founded in Delaware in 1984
by Dr. Kenneth Kensey and Mr. John Nash to develop advanced proprietary medical
products for use in the diagnosis and treatment of cardiovascular diseases.
Initially, the Company focused on rotary technology designed to treat
cardiovascular disease. As a result of this initial work, the Company
identified a market for, and began developing, puncture closure devices. In the
late 1980s, the Company began intensifying its development of puncture closure
devices, including the Angio-Seal Device (the "Angio-Seal"), and filed its
first patent related to the Angio-Seal in 1987. In 1991, the Company entered
into a long-term strategic relationship with American Home Products Corporation
("AHP" or "Strategic Alliance Partner") by entering into United States and
foreign license agreements (together, the "License Agreements"). These
agreements provided research and development and clinical trial funding as well
as significant payments upon the achievement of certain milestones in the
Angio-Seal development. As a result of the Company's clinical trial work, the 8
French ("F") Angio-Seal received Pre-Market Approval ("PMA") from the U.S. Food
and Drug Administration ("FDA") in September 1996 and the European Community
("CE") Mark approval from the European Economic Community ("EEC") in September
1995, the latter of which permits the marketing of the Angio-Seal in EEC member
countries. In December 1997, AHP announced the sales of its subsidiary,
Sherwood-Davis & Geck, the operating company responsible for the sales,
marketing and manufacturing of the Angio-Seal device, to Tyco International
Ltd. ("Tyco"). Under the terms of the sale, the Company's agreements with AHP
were transferred to Tyco's subsidiary, The Kendall Company ("Kendall").
Accordingly, Kendall replaced AHP as the Company's Strategic Alliance Partner
in March 1998, upon finalization of the sale.

     The Company has established three technology platforms; puncture
closure (the Angio-Seal), biomaterials (collagen and resorbable polymers) and
revascularization (the Aegis Vortex System) ("AVS"). The Company participates
in the puncture closure market primarily through its relationship with its
Strategic Alliance Partner. This partnership generates royalty income, research
and development funding and sales through the manufacture of clinical devices
and components for the Angio-Seal (see Relationship with Strategic Alliance
Partner).

     The Company has significantly expanded its biomaterials business with
growth in research and development, manufacturing and increased OEM sales and
marketing efforts.  The Company has a contract with its Strategic Alliance
Partner to supply a minimum of 50% of the collagen plug requirements until May
2000.  However, to-date, the Company has been exclusive manufacturer of the
collagen plug for the Angio-Seal puncture closure device.  In addition, the
Company manufactures collagen products for third parties for use as delivery
systems for various applications including bone growth proteins, artificial skin
for burn victims and drug delivery for products in various stages of clinical
trials. The Company has also been the exclusive manufacturer of the absorbable
polymer anchor component of the Angio-Seal. The Company will continue to be a
significant supplier of Angio-Seal anchor requirements through fiscal year 1999.
As a result of its absorbable polymer capabilities, the Company has expanded
into the orthopedic marketplace as an OEM supplier of specialized products.

     The Company's revascularization platform has been established to
address a market opportunity in cardiology for the treatment of occluded
saphenous vein bypass grafts and in-stent restenosis. The Company is developing
a revascularization catheter utilizing its patent portfolio and in-house
expertise to address these life threatening medical conditions.

     The Company wholly owns its Kensey Nash Holding Corporation subsidiary,
formed in 1992 to hold title to certain Company patents, which has no
operations.

PUNCTURE SEALING MARKET OVERVIEW

     Coronary artery disease, which affects millions of people each year, is
caused when organic material, known as plaque, develops on the inside walls of
the arteries that lead to the heart. The plaque build up can cause blood flow
restrictions, limiting oxygen to the heart, or complete obstructions, both of
which can cause severe chest pain and, ultimately, a heart attack. One of the
most common ways a physician will diagnose and treat coronary artery disease is
by performing a cardiovascular catheterization procedure. The physician gains
access to the heart by inserting a catheter into the femoral artery, located in
the groin area. Cardiovascular catheterization allows a physician to more
precisely assess the damage caused by the plaque to the artery and,
consequently, the heart. Peripheral vascular disease is assessed and treated
through similar catheterization procedures.

     Currently, over 5.2 million diagnostic cardiac catheterization
procedures, commonly referred to as angiographies, are performed worldwide each
year. During an angiography procedure, a dye is injected into the coronary
arteries and viewed on an x-ray imaging system to determine the extent and
location of arterial blockages. Once the physician determines the extent of the
blockages, any number of therapeutic procedures may be performed, sometimes
through the same access puncture.

     Typical therapeutic procedures include angioplasties, atherectomies,
and the placement of stents. An angioplasty is a procedure in which a balloon
is inserted into the artery and inflated to compress the blockage against the
arterial wall, enlarging the artery and increasing blood flow. An atherectomy
uses a miniature cutting system or a high speed rotating burr to debulk the
artery plaque. Recently, the placement of stents, used in conjunction with
these procedures, has become extremely popular and is one of the fastest
growing segments of this cardiovascular market. A stent is a metal device,
resembling a small coil, that is permanently implanted in an artery to support
the arterial wall and increase blood flow, therefore, reducing and delaying the
risk of the artery closing again (restenosis). In many of the therapeutic
procedures, such as atherectomies and the placement of stents, physicians use
high levels of anticoagulants (blood thinning therapies) and larger arterial
punctures, which often lead to increased bleeding and related puncture site
complications. Currently, there are an estimated 1.5 million total therapeutic
procedures performed worldwide each year. These procedures, due to their
potential puncture site complications, have created an increased awareness of
the need for arterial puncture closure devices.

     Together, there are currently over 6.7 million diagnostic and
therapeutic cardiac catheterizations performed each year. Depending on the
procedure, and the size of the catheter necessary to perform the procedure, a
cardiac catheterization creates a puncture in the artery that typically ranges
in size from a 5F to a 10F. The Company believes the Angio-Seal Product Line
addresses the needs of both the diagnostic and therapeutic cardiac
catheterization markets.

BIOMATERIALS MARKET OVERVIEW

     Biomaterials are substances of synthetic or natural origin which can
treat, augment or replace tissue, organs or functions of the body. There are
currently over 40 million medical treatments each year involving some form of
implantable biomaterial. Segments of the biomaterials market include wound
management, orthopedic implants and reconstructive surgery, drug delivery
systems, cardiovascular, dental, and blood transfusions. The Company's
biomaterials currently addresses several of these market segments, the largest
of which is orthopedics and wound management.

     Orthopedics. Biomaterials can be used to repair or regenerate most
musculoskeletal tissues, including bone, cartilage, ligaments, meniscus, spinal
discs and tendons. The worldwide biomaterials or thopedic device market is
estimated to be a multi-billion dollar market.  Collagen and polymers are among
the biomaterials currently used for musculoskeletal repair in the form of
bioresorbable fixation devices, bone replacement materials and bone growth
factors. Most of the top competitors in the orthopedics industry have ventured
into this new technology. These companies either have their own manufacturing
capabilities or look to third party manufacturers to bring their designs to the
market. The Company offers state-of the-art production capabilities and over a
decade of experience in

                                        
                                       3

developing and manufacturing medical products made from absorbable 
biomaterials. These capabilities and experience have enabled the Company to
develop relationships with several of the top competitors in the orthopedics
market on the design, development and/or manufacture of orthopedic
applications.

     Wound Management. The U.S. wound care market is a multi-billion dollar
industry currently dominated by conventional bandages and dressings and
surgical staples or sutures. There is a new generation of products which has
been triggered by recent developments in biomaterials, tissue engineering and
biotechnology. New products include genetically engineered topical drugs,
bioengineered artificial skin, wound healing devices and biosynthetic
dressings. Again, collagen and polymers are among the biomaterials being
integrated into the wound care market. The Company's products have been used as
an integral part of wound care products as diverse as hemostatic sponges,
topical wound dressings, bioengineered skin and drug delivery matrices.

REVASCULARIZATION MARKET OVERVIEW

     Revascularization is the treatment of occluded coronary arteries, both
native and grafts. When a native coronary artery is totally occluded a coronary
artery bypass graft procedure ("CABG") is performed to circumvent the native
artery and restore bloodflow to the heart via the graft. The bypass graft is
typically harvested from the patient's leg (the saphenous vein) and the graft
is referred to as a saphenous vein graft ("SVG"). There are approximately
700,000 worldwide coronary artery bypass surgeries performed annually, the
majority of these surgeries involve three or more bypassed vessels. The SVGs
occlude over time and it is estimated between 15%-30% are occluded after one
year. The Company believes the total market for occluded SVGs to be
approximately 250,000 annual procedures with a market size of $300 million.

     The current treatment options include pharmaceutical management, repeat
bypass surgery, percutaneous intervention and heart transplant. The Company
believes it has a unique device, the Aegis Vortex System, a percutaneous
interventional treatment, which targets the SVGs.

BUSINESS STRATEGY

     The Company's primary goal is to establish the Angio-Seal Product Line
as the standard of care for closing arterial puncture sites associated with
cardiovascular catheterizations. The Company continues to expand and research
other technologies. The Company's goals are and will continue to be pursued
through the following strategy:

     -    Expand Angio-Seal Product Technology.  The Company's approved 8F 
          Angio-Seal device seals arterial punctures 8F and smaller
          and addresses the vast diagnostic  market as well as balloon 
          angioplasty and stenting.  The Company is currently expanding 
          its Angio-Seal Product Line by developing additional sizes of
          the Angio-Seal, including 6F and 10F sizes.  The 6F Angio-Seal 
          addresses the diagnostic and therapeutic market which may use 
          smaller puncture sites.  The 10F Angio-Seal addresses the market
          for therapeutic procedures which require larger puncture sizes. 
          The Company has begun  clinical trials and, together with its
          Strategic Alliance Partner, is aggressively pursuing all
          necessary regulatory approvals for both the 6F and the 10F
          Angio-Seal.

     -    Expand Collagen Business. While the Company's original purpose
          in manufacturing collagen and absorbable polymer components is to
          supply its Strategic Alliance Partner for the Angio-Seal Product
          Line, the Company has developed significant expertise in the
          processing, handling and manufacturing of bioresorbable materials.
          The company manufactures several standard collagen products and has
          made it a practice to customize materials to meet specific customer
          specifications. The company's collagen has been used as an integral
          part of products as diverse as hemostatic sponges, topical wound
          dressings, bioengineered skin, bone regeneration and drug delivery
          matrices.


                                        
                                       4



<PAGE>   5


     -    Expand Polymer Business. Recent advances in biotechnology,
          biomaterials and tissue engineering have made absorbable polymers one
          of the fastest growing segments within the medical field,
          particularly in orthopedics. The company provides a full array of
          mold design, injection-molding and compression molding services for
          absorbable polymers, tailored to meet the unique requirements of
          medical product manufacturers. The Company intends to utilize its
          expertise to build a position in the market as a supplier of
          absorbable polymer and is currently working with several companies
          that are leaders in the orthopedic market.

     -    Develop Revascularization Technology. The Company currently has
          proprietary technology covered by issued patents related to the use
          of revascularization technology for the treatment of cardiovascular
          disease in the coronary arteries. The Company is developing this
          technology for application in opening occluded coronary artery bypass
          grafts and possibly in-stent restenosis. The Company believes it has
          a unique device, the Aegis Vortex System, for treating this currently
          unaddressed problem. Clinical trials are expected to commence in
          fiscal year 1999.

     -    Develop Opportunities in Other Technology.  The Company will
          continue to focus its research and development capabilities on
          developing new products that relate to its three technology
          platforms: puncture closure, biomaterials and revascularization. 
          Using its expertise in these platforms, the Company believes products
          will be developed with significant market potential.

 (2) These sizes of the device are not included in the PMA for the Angio-Seal.
     PMA supplements containing data from the ongoing clinical trials will need
     to be filed and approved for these sizes before they can be commercially
     marketed in the United States.
 (3) The collagen plug and anchor are components for the different sizes of the
     Angio-Seal. Because the FDA and foreign regulatory bodies generally approve
     devices as complete systems, the regulatory status for each component for a
     specific size device is equivalent to that of the specific size Angio-Seal.

ANGIO-SEAL
     The Angio-Seal Technology. The Angio-Seal acts to close and seal femoral
artery punctures made during diagnostic and therapeutic cardiovascular
catheterizations. The device consists of four components: an absorbable anchor
that is seated securely against the inside surface of a patient's artery at the
point of puncture, an absorbable collagen plug that is applied adjacent to the
outside of the artery wall, an absorbable suture and a delivery system. The
delivery system consists of an insertion sheath, puncture locator, guidewire,
tamper tube and spring. The anchor and suture act as a pulley to position the
collagen into the puncture tract, adjacent to the outside of the artery wall, to
seal the puncture. The collagen induces the blood-clotting process at the
puncture site and the anchor is designed to encapsulate into the artery wall.
Based on the characteristics of the materials used, the anchor, collagen and
suture are all absorbed into the patient's body within 60 to 90 days after the
procedure. The Company believes that this mechanical (via the anchor) and
biochemical (via the collagen) seal offers physicians a method for closing
punctures with significant advantages over traditional manual or mechanical
compression methods and other competitive products.

     How the Angio-Seal Is Used. The Angio-Seal is designed and clinically
proven to take a trained healthcare professional less than two minutes to place.
After a cardiovascular catheterization is completed and the introducer for the
procedure is ready to be removed, the insertion sheath and puncture locator
supplied with the Angio-Seal are inserted into the artery over the guide wire,
using standard introducer exchange techniques. The guide wire is then removed
and the anchor is inserted into the artery through the delivery system. The
delivery system is pulled back until the anchor is secured onto the inside
surface of the artery wall at the puncture site. As the delivery system is
withdrawn from the tissue surrounding the artery, the collagen plug is deployed
from the delivery system into the puncture tract adjacent to the outside of the
artery wall. When the 

                                        
                                       6


<PAGE>   7


delivery system is removed from the tissue surrounding the artery, the  
Angio-Seal's anchor and suture act as a pulley to compress the collagen within
the puncture tract adjacent to the outside of the artery wall. The exposed
tamper tube is used to compress the collagen further. A spring is then attached
to the suture to maintain light pressure on the tamper tube. After 20 to 30
minutes, the spring and the tamper tube are removed and the suture is cut below
the skin.

     Advantages of the Angio-Seal over Manual and Mechanical Compression..
Until recently, closing arterial punctures resulting from cardiovascular
catheterizations was generally limited to manual or mechanical compression of
the puncture site following the procedure. The Company believes, based on
results of clinical trials and published reports, that the Angio-Seal has the
following advantages over manual or mechanical compression:

     -    Reduced Time to Ambulation. Clinical studies have shown reductions in
          the amount of time required for the removal of the introducer sheath
          used during the procedure and reduced times to hemostasis. A PMA
          supplement was approved in September 1997 allowing the Company to
          expand the labeling of the Angio-Seal to include time-to-ambulation
          data (mean time to ambulation for Angio-Seal of 1.4 hours verses 6.6
          hours for manual compression).


     -    Reduced Staffing and Hospital Time. The reduction or elimination 
          of post-procedure manual compression, as well as reduced needs 
          for post-procedure examinations, may decrease the staff time
          associated with the procedure and follow-up care and lead to more
          efficient use of hospital personnel and space.


     -    Possible Reduction in Procedure Cost. The faster treatment time
          and reduced staffing requirements should reduce the costs of the
          typical cardiovascular catheterization. In addition, hospitals should
          enjoy greater efficiency in catheterization lab scheduling, greater
          flexibility in the use of physical space reserved for catheterization
          patients and have the possibility for greater catheterization lab
          throughput.

     -    Increased Patient Comfort. Patients generally regard the manual
          compression following cardiovascular catheterization as the most
          painful aspect of the procedure. The Angio-Seal device requires little
          or no manual pressure, reducing the pain and discomfort associated
          with current methods of puncture site hemostasis. In addition, it
          eliminates the need for pressure dressings leading to less restriction
          and discomfort for the patient.


     -    Greater Flexibility in Post Procedure Anticoagulation Therapy.
          In highly anticoagulated patients, physicians typically discontinue
          blood thinning therapy in order to effectively stop the bleeding at
          the arterial puncture, despite the importance of the therapy in
          minimizing the formation of blood clots. Based upon published results,
          the Angio-Seal device provides fast, reliable hemostasis, independent
          of heparin levels (a common anticoagulant therapy).


     -    Increased Blood Flow to the Leg. The Angio-Seal allows for
          greater blood flow to the patient's leg during a cardiovascular
          catheterization procedure than does manual compression, thereby
          reducing the possibility of vessel blockages in the leg.

     The Angio-Seal is currently the puncture closure device market leader
with almost 300,000 devices sold to-date. The Company believes that the
Angio-Seal offers advantages over the competing methodologies (see Competition)
in its ability to provide quickly and easily both a mechanical and biochemical
seal of arterial punctures.

AEGIS VORTEX SYSTEM
     System Technology. The Company is developing a product, the Aegis Vortex
System, for the percutaneous intervention of diseased SVGs. The AVS is being
designed to recanalize diseased vein grafts by debulking and aspirating the
occlusive material associated with diseased SVGs. A revolving tip breaks the
occluding material into small fragments while a balloon is placed distally to
prevent embolization of particulate generated during the revascularization
procedure. The particulate is removed by an extraction pump, which is included
in the system.

     The current available treatment options include pharmaceutical
management, repeat bypass surgery, percutaneous intervention and heart
transplant. The AVS, a percutaneous interventional treatment, is designed to
improve clinical outcomes while reducing patient trauma and reducing cost. The
Company intends to start U.S. and international clinical trials in fiscal year
1999.

CLINICAL TRIALS AND REGULATORY STATUS
     The Company obtained CE Mark approval from the EEC in September 1995 and
FDA approval in the United States in September 1996 for its 8F Angio-Seal
device.

     In September 1997, the Company received a PMA supplement approval
allowing the Company to make additional labeling claims regarding early
ambulation in diagnostic angiography patients.

     Initial clinical trials ("pilot studies") on both the 6F and 10F
Angio-Seal devices were completed in September 1997. The company began pivotal
studies immediately following completion of the pilot studies for the 6F and 10F
Angio-Seal. To date, the 6F pivotal study is being conducted at seven sites with
164 patients enrolled and the 10F pivotal study has 377 patients enrolled at
twelve sites. The Company has implemented design enhancements in conjunction
with the clinical studies. Both of these studies are expected to be completed
during fiscal year 1999.

     In September 1998, the Company submitted an IDE to the FDA for its
revascularization product, the AVS. The Company expects clinical trials to
commence in fiscal year 1999.

RELATIONSHIP WITH STRATEGIC ALLIANCE PARTNER
     The Company embarked on a long-term strategic relationship with AHP
beginning in 1991 which incorporated United States and foreign license
agreements (the License Agreements), a research and development agreement, a
collagen supply agreement and a credit agreement (collectively, the "Strategic
Alliance Agreements"). In December 1997, AHP announced the sale of its
subsidiary, Sherwood-Davis & Geck, the operating company responsible for the
sales, marketing and manufacturing of the Angio-Seal device, to Tyco
International Ltd. Under the terms of the sale, the Company's Strategic Alliance
Agreements with AHP were transferred to Tyco's subsidiary, The Kendall Company.
Accordingly, Kendall replaced AHP as the Company's Strategic Alliance Partner in
March 1998, upon finalization of the sale. The Company's relationship with its
Strategic Alliance Partner has enabled the Company to obtain critical funding to
research and develop the Angio-Seal, conduct clinical trials and gain regulatory
approval in the U.S. and Europe. This relationship provides access for the
Angio-Seal Product Line to the major worldwide markets.

     The License Agreements. The License Agreements, entered into in September
1991, grant a worldwide exclusive license to the Company's Strategic Alliance
Partner to manufacture and market all current and future sizes of the Angio-Seal
Product Line for use in the cardiovascular system. The term "Angio-Seal" is a
trademark of the Strategic Alliance Partner. The Company retains the rights of
use for the puncture closure technology for other applications. Through fiscal
1997, the Company earned $13.5 million in licensing and milestone fees, as well
as received a $3 million royalty advance, from its Strategic Alliance Partner
pursuant to the terms of the license agreements.  

                                        
                                       8



<PAGE>   9

         Under the License Agreements, the Company earns royalties based upon
the sales price of the Angio-Seal Product Line sold worldwide by its Strategic
Alliance Partner. These rates vary depending upon the level of units sold. In
November 1997, the Company also acquired a patent portfolio as well as the
rights of the seller under a pre-existing licensing agreement with AHP. As a
result of this acquisition the Company now receives royalties under its existing
Licensing Agreements as well as royalties formerly paid to the seller under a
separate licensing agreement (combined, the "Royalty Agreements"). The Royalty
Agreements provide for minimum royalty payments for five years following FDA
approval, which range from $450,000 in the first year to $4.1 million in the
fifth year. If the Strategic Alliance Partner fails to pay the minimum, the
Company is entitled to convert all of the Strategic Alliance Partner's rights
under the License Agreements from exclusive to non-exclusive. Such right of
conversion is the Company's sole remedy for the Strategic Alliance Partner's
failure to make any minimum royalty payment, and if it is exercised, the
Strategic Alliance Partner has no further obligation to make any minimum royalty
payments to the Company.

         The term of each of the License Agreements extends to the last to
expire of the licensed patents and all continuations or supplements thereto. The
most recently issued patent for the Angio-Seal technology was issued in 1998,
although the Company has applied for, and expects to have issued, additional
patents in the future. The Strategic Alliance Partner may terminate the License
Agreements any time after the fifth royalty year for any reason upon 12-months
notice.

         If a license under any third-party patent is necessary to make, use or
sell the Angio-Seal Product Line, any payments and royalties for such
third-party license, and any related attorney's fees, will be deducted from
payments due to the Company, on a territory-by-territory basis, in an amount in
any one year not to exceed one-half of any royalties in any such territory for
such year.

         The Research and Development Agreement. Pursuant to a research and
development agreement ("R&D Agreement") entered into with the Company's
Strategic Alliance Partner in November 1995 the Company has agreed to develop
additional sizes of and enhancements to the Angio-Seal Product Line, conduct
certain United States and selected foreign clinical trials of various sizes of
the Angio-Seal Product Line and to assist the Strategic Alliance Partner with
certain foreign trials. Under the R&D Agreement, the Strategic Alliance Partner
reimburses the Company for two-thirds of expenses incurred under these programs.
The Strategic Alliance Partner can terminate the R&D Agreement upon 60 days
notice. The termination of the R&D Agreement with the Strategic Alliance Partner
could have a material adverse effect on the operations of the Company. As of
June 30, 1998, the Company has earned $12.3 million in research and development
revenue from its Strategic Alliance Partner. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" included herein at
Item 7.

         The Collagen Supply Agreement. Pursuant to an agreement entered into
with the Company's Strategic Alliance Partner in May 1995 (the "Collagen Supply
Agreement"), the Strategic Alliance Partner agreed to purchase at least 50% of
its collagen needs for the Angio-Seal on a per country basis (which amount
represents 


                                       9



<PAGE>   10


the Strategic Alliance Partner's "Minimum Purchase Requirement") for
the Angio-Seal from the Company for five years beginning May 31, 1995. The
Company is required to maintain a "safety stock inventory" of collagen in an
amount equal to two times the Strategic Alliance Partner's average monthly
collagen requirement based upon its projections. Either the Strategic Alliance
Partner or the Company may terminate the Collagen Supply Agreement upon thirty
days written notice.

SALES AND MARKETING
         The Strategic Alliance Partner (Kendall), is responsible for both
domestic and international sales of the Angio-Seal. European sales of the
Angio-Seal commenced on a limited basis in December 1994 following marketing
approval in France. The Angio-Seal received its CE Mark approval from the EEC in
September 1995, which permits marketing of the Angio-Seal in EEC member
countries, and U.S. FDA approval in September 1996. The Angio-Seal is currently
being sold in the U.S., Canada, the UK, Germany, Italy, France, Switzerland,
Australia, Saudi Arabia, Israel, Austria, Spain, Malta and the Netherlands by a
dedicated Kendall sales force. To date, there have been over 300,000 devices
sold to end users. Kendall plans on introducing the Angio-Seal in additional
countries around the world during 1999.

         Kendall is selling the Angio-Seal through dedicated sales forces of 65
and 22 persons in the U.S. and Europe, respectively. Both the Company and
Kendall believe that dedicated sales forces are appropriate to cover the
concentrated market of cardiovascular catheterization facilities that perform
the majority of these procedures.

         The Company has historically sold Angio-Seal subassemblies to its
Strategic Alliance Partner. The Company expects to continue to sell collagen and
anchor components to its Strategic Alliance Partner. See "Relationship with
Strategic Alliance Partner"

         While the Company assists its Strategic Alliance Partner in training
and conducting clinical trials, the Strategic Alliance Partner has the sole
right to determine the worldwide marketing and pricing strategy for the
Angio-Seal Product Line.

         As the Company develops new products, such as the Aegis Vortex System,
it will continue to explore a variety of means to market and sell such products
if and when they receive appropriate regulatory approvals. Such means include,
but are not limited to, contracting with distributors, developing its own sales
force and licensing products to third parties.

CUSTOMERS
         Sales to the Company's Strategic Alliance Partner comprised 86%, 91%
and 81% in the years ended June 30, 1998, 1997 and 1996, respectively, of total
sales for the Company. The loss of the Strategic Alliance Partner as a customer
would have a material adverse impact on the Company.

THIRD-PARTY REIMBURSEMENT
         The Company believes that continued sales growth of the Angio-Seal may
depend not only on its clinical efficacy and cost effectiveness, but also in
part on the availability of third-party reimbursement. Separate reimbursement
for the Angio-Seal is not expected to be available in the United States and
there can be no assurance that reimbursement for the Angio-Seal will be
available in international markets under either governmental or private
reimbursement systems. In the United States, healthcare providers, such as
hospitals and physicians, that purchase medical devices such as the Angio-Seal,
generally rely on third-party payers, principally federal Medicare, state
Medicaid and private health insurance plans, to reimburse all or part of the
cost of therapeutic and diagnostic cardiovascular catheterization procedures.
Reimbursement for


                                       10




<PAGE>   11


cardiovascular catheterization procedures performed using devices that have
received FDA approval has generally been available in the United States. The
Company anticipates that in prospective payment systems, and in many managed
care systems used by private healthcare payers, the cost of the Company's
products will be incorporated into the overall cost of the procedure and that
there will be no separate additional reimbursement for the Company's products.
The Company anticipates the hospital administrators and physicians will justify
the additional cost of an arterial access site closure device by the attendant
cost savings and clinical benefits derived from the use of the Angio-Seal.

         To date, the Company's Strategic Alliance Partner has focused on
obtaining reimbursement approvals in international markets. The main types of
reimbursement systems in international markets are government sponsored
healthcare and private insurance. Countries with government sponsored
healthcare, such as the United Kingdom, Italy and the Netherlands, have a
centralized, nationalized healthcare system. In most foreign countries, there
are also private insurance systems that may offer payments for alternative
therapies. Although not as prevalent as in the United States, health maintenance
organizations are beginning to appear in Europe, particularly in Spain.
Regardless of the type of reimbursement system, the Company believes that
physician advocacy of the Angio-Seal will be the key to obtaining third-party
reimbursement. The Company could be materially adversely affected by changes in
reimbursement policies of governmental or private health care payers.

MANUFACTURING, RAW MATERIALS AND SUPPLIES
         The Company has developed manufacturing expertise in the assembly and
testing of technologically advanced medical products. The Company's
manufacturing activities to date have consisted primarily of producing the
Angio-Seal for use by clinical investigators and producing sub-assemblies of the
Angio-Seal for sale to customers in Europe. 

         The Company also currently manufactures and supplies 100% of the
bioresorbable components of the Angio-Seal, the collagen plug and resorbable
polymer anchor, to fulfill the Strategic Alliance Partner's requirements for the
Angio-Seal. The Company has a contract with its Strategic Alliance Partner to
supply a minimum of 50% of the collagen needs for the Angio-Seal on a
country-by-country basis through 2000. The Company is also the only approved
supplier of collagen approved for use in the Angio-Seal in the EEC. In the U.S.
the current Angio-Seal PMA includes the Company's absorbable anchor and collagen
plug. The anchor component of the Angio-Seal has been manufactured exclusively
by the Company and the Company will continue to provide a significant amount of
the anchor requirements through fiscal year 1999.

         The Company purchases most raw materials, parts and peripheral
components used in its products. Although many of these supplies are
off-the-shelf items readily available from several supply sources, others are
custom-made for the Company to meet its specifications. The Company believes
that, in most of these cases, alternative sources of supply for custom-made
materials are available or could be developed within a reasonable period of
time. The Company has generally been able to obtain adequate supplies of all
materials, parts and components in a timely manner from existing sources. When
this has not proven feasible, the Company has brought the production of those
critical parts under its own manufacturing control. However, the inability to
develop alternative suppliers for present and future needs, if required, or a
reduction or interruption in supply or a significant increase in the price of
materials, parts or components could adversely impact the Company's operations.
Several of the Company's raw materials are derived from natural sources and
carry the inherent risk of disease or contamination of source material. In those
areas in which natural raw material sourcing has presented the potential for
contamination, the Company has taken steps which it believes will assure itself
and its customers of the purity of these products. The validation of the purity
of these raw materials and/or the ability of the Company processes to inactivate
potential contaminants has been undertaken at significant expense by the Company
to preclude withdrawal or restriction of these products by regulatory agencies
in any country. The Company will, as a practice, continue to take these steps in
any area in which biological or other contaminants may compromise a raw material
supply.


                                       11


<PAGE>   12

The Company's manufacturing facilities in Exton, Pennsylvania, contain separate
areas for Angio-Seal assembly, collagen manufacturing and polymer manufacturing.
In addition, the Company has its own capabilities in tool and die making,
injection molding, model making and laser welding, which allows it to engineer
and reengineer its products in development on site. The Company's FDA-registered
facility is equipped with multiple class 100,000 clean room facilities and is
certified to the two international quality standards, ISO 9001 and EN 46001.
Certification is based on adherence to established standards of quality
assurance and manufacturing process control. For this reason, the Company's
manufacturing facilities are subject to regulatory requirements and periodic
inspection by regulatory authorities. The Company has a separate in-house
quality control department that sets standards, monitors production, writes and
reviews operating procedures and protocols and performs final testing of samples
of devices and products manufactured by or for the Company. See "Government
Regulation."

         The Company believes that its current manufacturing capabilities and
capacity are sufficient to produce its products to supplement its Strategic
Alliance Partner's manufacturing capabilities, supply the anchor and collagen
plug components and produce additional sizes of the Angio-Seal in initial
quantities at such time as the devices may be approved for sale in the United
States or elsewhere.

RESEARCH AND DEVELOPMENT
         The Company's research and development and regulatory staff consisted
of 36 individuals as of September 18, 1998. Since signing the License Agreements
in September 1991, the Company's research and development effort has focused on
designing the Angio-Seal, supporting clinical trials, seeking regulatory
approval in the United States and Europe and establishing a technology base in
puncture closure devices. The Company continues to focus its research and
development efforts on creating additional sizes of the Angio-Seal Product Line
and product enhancements, a significant portion of which the Company expects to
be funded by its Strategic Alliance Partner. The Company is also concentrating
on the development of its revascularization technology, the AVS, for opening
occluded coronary artery bypass grafts and has other projects in the early
stages of development. The Company incurred total research and development
expenses of $5.5, $4.7 and $3.6 million in the fiscal years ended June 30, 1998,
1997 and 1996, respectively.

         In addition to the resources dedicated to the product development
process, the Company has an internal regulatory affairs and clinical monitoring
staff, which has had and continues to have responsibility for establishing,
monitoring, collecting and analyzing data relating to clinical trials and works
closely with its Strategic Alliance Partner on gaining regulatory approvals for
additions to the Angio-Seal Product Line in the United States and, in some
instances, abroad.

COMPETITION
         The primary competition for the Angio-Seal is the current standard of
care, manual pressure. Manual pressure is an inherently cumbersome procedure
which is costly, complicated and associated with high levels of patient
discomfort. Although the Company believes that the Angio-Seal competes favorably
with the application of manual and/or mechanical compression as a standard of
care, the acceptance of new methodologies and technologies is inherently
uncertain. In addition, the Company is aware of competitors trying to develop
noninvasive and/or pharmaceutical products which could render the Angio-Seal
Product Line technology obsolete. Many of these organizations, and certain other
medical device companies that may enter the markets in which the Company does or
will compete, are larger and have more extensive financial, technical,
managerial, research and development and marketing resources than the Company or
its Strategic Alliance Partner. The Company is aware of competitors who have
developed and commercialized devices to seal arterial punctures, including
Datascope, Perclose and Vascular Solutions. The Company is also aware of other
companies who are developing proposed products.

         Datascope's VasoSeal vascular hemostasis device, approved by the FDA in
September 1995, works by delivering a collagen plug into the tissue tract
outside of the artery. Once positioned in the tissue tract, the 

                                        
                                       12



<PAGE>   13


biochemical interaction between collagen and blood platelets acts to create a
hemostatic seal at the puncture site. The VasoSeal requires measurement of the
collagen plug prior to delivery and does not have an anchor to prevent the
collagen from entering the artery. In August 1998 Datascope announced it had
received CE mark approval for a second generation device, VasoSeal ES. According
to Datascope, The VasoSeal ES eliminates the need to measure the collagen prior
to a procedure and is a one-size-fits-all device.

         Perclose's Prostar and Techstar vascular surgical systems consist of
catheter-based instruments designed to mechanically suture arterial access sites
below the skin following cardiovascular catheterization procedures. The 9-11F
Prostar was approved by the FDA in April 1997 and PMA supplements for Perclose's
second generation devices, the Techstar (6-8F) and the Prostar Plus (8-10F) were
approved in November 1997 and January 1998, respectively.

         A new entrant to the puncture closure market is Vascular Solutions, who
has developed a sealing device catheter, the Duett. The device employs a balloon
inserted over the guidewire into the femoral artery to temporarily close the
entry channel. A mixture of collagen and thrombin is then injected into the
puncture site to close the wound after a period of compression. The Duett
received CE Mark approval in July 1998 and the company commenced clinical
studies in the U.S. in August 1998.

         The Angio-Seal is currently the puncture closure device market leader
with almost 300,000 devices sold to-date and believes that its continued
competitive success will depend upon several factors. These factors include its
ability to create and maintain technologically advanced proprietary medical
products, to obtain patents or other protection for these technologies and to
apply these technologies across several different product opportunities and
markets, to attract and retain high quality engineering and scientific
personnel, to obtain timely regulatory approvals when possible, and to
manufacture and market its products in a cost-effective manner whether through
internal means or through outside parties. See "Angio-Seal."

GOVERNMENT REGULATION
         The medical devices marketed and manufactured by the Company and its
Strategic Alliance Partner are subject to extensive regulation by the FDA, and,
in some instances, by foreign governments. Pursuant to the Federal Food, Drug,
and Cosmetic Act of 1976, as amended, and the regulations promulgated thereunder
(the "Act"), the FDA regulates the clinical testing, manufacture, labeling,
distribution, and promotion of medical devices. Noncompliance with applicable
requirements can result in, among other things, fines, injunctions, civil
penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant pre-market clearance or
pre-market approval for devices, withdrawal of marketing approvals and criminal
prosecution. The FDA also has the authority to request repair, replacement or
refund of the cost of any device manufactured or distributed by the Company.
Noncompliance with applicable requirements on the part of the Company's
Strategic Alliance Partner with respect to the Angio-Seal, or by the Company,
could have a material adverse impact on the Company.

         The Company obtained PMA approval on the Angio-Seal 8F device in
September 1996, the ownership of which was subsequently transferred to its
Strategic Alliance Partner. The Strategic Alliance Partner will be responsible
for all future amendments and PMA supplements for the Angio-Seal device,
including PMA supplements necessary to market the 6F and 10F size Angio-Seal
devices in the United States. However, there can be no assurance that the
Strategic Alliance Partner will be able to obtain necessary regulatory approvals
or clearances on the Angio-Seal Product Line on a timely basis or at all, and
delays in receipt of or failure to receive such approvals, the loss of
previously received approvals, or failure to comply with existing or future
regulatory requirements would have a material adverse impact on the Company's
business, financial condition and results of operation.

         The Angio-Seal received CE Mark approval from the EEC in September
1995, which permits marketing of the Angio-Seal in EEC member countries and it
is also available for sale in several other countries. International sales of
medical devices are subject to the regulatory agency product registration
requirements of each country. The regulatory review process varies from country
to country. Many 


                                       13

countries also impose product standards, packaging requirements,
labeling requirements and import restrictions on devices. Delays in receipt of,
or a failure to receive approvals or clearances, or the loss of any previously
received approvals or clearances, could have a material adverse effect on the
Company's business, financial condition and results of operations.

         Any products manufactured or distributed by the Company pursuant to FDA
clearance or approvals are subject to pervasive and continuing regulation by the
FDA including record keeping requirements and reporting of adverse experiences
with the use of the device. Device manufacturers are required to register their
establishments and list their devices with the FDA and are subject to periodic
inspections by the FDA and certain state agencies. The Act requires devices to
be manufactured in accordance with Good Manufacturing Practices ("GMP")
regulations which impose certain procedural and documentation requirements upon
the Company and its Strategic Alliance Partner with respect to manufacturing and
quality assurance activities. Labeling and promotional activities are subject to
scrutiny by the FDA and, in certain instances, by the Federal Trade Commission.
The FDA actively enforces regulations prohibiting marketing of products for
unapproved uses. Changes in existing requirements or adoption of new
requirements or policies could adversely affect the ability of the Company to
comply with regulatory requirements. Failure to comply with regulatory
requirements could have a material adverse impact on the Company's business,
financial condition and results of operations. There can be no assurance that
the Company will not be required to incur significant costs to comply with laws
and regulations in the future or that laws or regulations will not have a
material adverse impact upon the Company's business, financial condition or
results of operations.

         Manufacturers are also subject to numerous federal, state and local
laws relating to such matters as safe working conditions, manufacturing
practices, environmental protection, fire hazard control and disposal of
hazardous or potentially hazardous substances. There can be no assurance that
the Company or its Strategic Alliance Partner will not be required to incur
significant costs to comply with such laws and regulations in the future or that
such laws or regulations will not have a material adverse effect upon the
Company's or its Strategic Alliance Partner's ability to do business.

PATENTS AND PROPRIETARY RIGHTS
         The Company's policy is to protect its technology by, among other
things, filing patent applications for the patentable technologies that it
considers material to the development of its business. The Company first filed
for patent protection for the concept of sealing arterial punctures in the
United States in 1987 and was first issued a United States patent in 1988. As of
August 31, 1998, the Company held 49 United States patents and 62 foreign
national patents and has pending several United States patents and foreign
national patent applications that cover various aspects of its technology. The
Company also has a number of files of potential patent application material at
its patent counsel's office. In addition, the Company holds the exclusive or
joint rights to inventions that result from a number of agreements among the
Company, leading medical institutions and their principal investigators. There
can be no assurance that patent applications filed by the Company will result in
the issuance of patents or that any patents or licenses now or hereafter held by
the Company will provide competitive advantages for the Company or its
licensees, or that these patents or licenses will not be challenged or
circumvented by competitors.

         The Company also relies heavily on trade secrets and unpatented
proprietary know-how which the Company seeks to protect, in part through
non-disclosure agreements with all corporations, institutions, and individuals
that are exposed to the Company's proprietary information. It is the Company's
policy to require, as a condition of employment, that all full-time and
part-time employees enter into an assignment and non-disclosure agreement with
the Company. There can be no assurance that these and other agreements
specifically constructed to protect the Company will not be breached or that
others will not independently develop the same or similar technology.

         There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry. Litigation, which
would result in substantial cost to and diversion of effort by the 


                                       14




<PAGE>   15

Company, may be necessary to enforce patents issued to the Company, to
protect trade secrets, know-how, or other proprietary rights owned by the
Company or to defend the Company against claimed infringement of the rights of
others and to determine the scope and validity of the proprietary rights of
others. Adverse determinations in litigation could subject the Company to
significant liabilities to third parties, could require the Company to seek
licenses from third parties and could prevent the Company and/or its licensees
from manufacturing, selling or using its products, any of which could have a
material adverse impact on the Company's business, financial condition and
result of operations. It is possible that the Company, in the course of new
product development and introduction, may need to acquire licenses to, or
contest the validity of, issued or pending patents of third parties relating to
the Company's technology or to products presently under license or under
development by the Company. There can be no assurance that any license required
under any such patent would be made available to the Company on acceptable
terms, if at all, or that the Company would prevail in such a patent dispute.

         In March 1998, the Company, together with its Strategic Alliance
Partner, filed a patent infringement suit against Perclose, Inc. For more
information on this suit, see "Legal Proceedings".

         The Company has licensed its United States and foreign patents for the
Angio-Seal to its Strategic Alliance Partner, and is obliged to license all
improvements for the same product to its Strategic Alliance Partner in the
future at no additional charge. The License Agreements are exclusive, worldwide,
with rights to make, have made, use, sell, and have sold the Angio-Seal, but are
limited to the cardiovascular field of use only, leaving all other fields of use
in the Company's possession. The licenses include rights to use related trade
secrets and know-how.

PRODUCT LIABILITY
         The clinical testing, marketing and sale of human healthcare products
entails an inherent risk of product liability claims. There can be no assurance
that product liability claims will not be asserted against the Company or its
licensees. Although the Company maintains product and clinical trials liability
insurance in the aggregate amount of $12 million, there can be no assurance that
product liability claims will not exceed such insurance coverage limits, that
claims for coverage would not be denied or that such insurance will be available
in the future on commercially reasonable terms, if at all. The Company believes
that its Strategic Alliance Partner self insures for product liability claims.
There can be no assurance that liability claims made against its Strategic
Alliance Partner or other potential licensees will not result in any claims
against the Company

EMPLOYEES AND CONSULTANTS
         As of September 18, 1998, the Company had 100 employees, including 51
in operations, 31 in research and development, 12 in finance and administration,
five in clinical and regulatory affairs and one in sales and marketing. All of
the Company's employees are located at the Company's facility in Pennsylvania.
The Company believes that its success is dependent in a large part on its
ability to attract and retain employees in all areas of its business.

         The Company maintains continuing relationships with a number of
independent consultants that have contributed to the development of the
Company's products and work on specific development projects. These
relationships are integral to the continued success of the Company and the
generation of new products from the research and development departments.

         The Company is dependent upon a number of key management and technical
employees. The loss of services of one or more key employees could have a
material adverse impact on the Company. None of the Company's employees are
covered by a collective bargaining agreement. The Company believes its
relationship with its employees is good.

ITEM 2.  PROPERTIES
         The Company leases approximately 44,000 square feet of executive
offices, manufacturing and research and development facilities in Exton,
Pennsylvania, a suburb of Philadelphia. The lease expires in 2002, subject to
renewal options. The Company believes that the complex in which the current
facilities are located offers the necessary space for required expansion over
the foreseeable future.

ITEM 3.  LEGAL PROCEEDINGS
         In March 1998, the Company, together with its Strategic Alliance
Partner, filed a patent infringement claim against Perclose, Inc. of Menlo Park,
California, a competitor in the puncture closure market. The suit, filed in the
Eastern District of Pennsylvania, claims that Perclose infringes the Company's
U.S Patent No. 5,676,689 (the "Patent"). The Patent covers a system and method
for sealing a puncture in a blood vessel (e.g. the femoral artery). The Company
seeks damages and an order to permanently enjoin Perclose from making, using or
selling product that infringes the Patent.

         Perclose filed four counterclaims in answer to the complaint. The first
counterclaim seeks to declare the Patent invalid and not infringed; the second
and third counterclaims maintain that the Company committed antitrust
violations; and the fourth counterclaim asserts that the Company committed
unfair competition. Management is unable to predict the final outcome of the
suit or whether the resolution of the matter could materially affect the
Company's results of operations, cash flows, or financial position.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITIES HOLDERS
         No matters were submitted to a vote of security holders in the fourth
quarter of fiscal 1998.

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

OVERVIEW
         The Company is a medical device company which has established three
technology platforms; puncture closure (the Angio-Seal), biomaterials (collagen
and resorbable polymers) and revascularization (the Aegis Vortex System)
("AVS"). The Company participates in the puncture closure market primarily
through its relationship with its Strategic Alliance Partner, which generates
royalty income, research and development funding and sales revenue through the
manufacture of clinical devices and components for the Angio-Seal.

         The Company's operations are focused on the commercialization and
continuing development of its proprietary principal product, the Angio-Seal
Product Line, the continued expansion of its capabilities in biomaterials, and
the development of its revascularization catheter system, the Aegis Vortex
System. The Angio-Seal is a device for the sealing of arterial punctures created
during diagnostic and therapeutic cardiovascular procedures such as angiography,
angioplasty, atherectomy and the placement of stents.

         The Company is currently manufacturing collagen products for third
parties for use as delivery systems for various applications including bone
growth proteins, artificial skin for burn victims and drug delivery for products
in various stages of clinical trials. As a result of its absorbable polymer
capabilities, the Company has expanded into the orthopedic marketplace as an OEM
supplier of specialized products.

         The Company's revascularization platform has been established to
address a market opportunity in cardiology for the treatment of occluded
saphenous vein bypass grafts and in-stent restenosis. The Company is developing
a revascularization catheter system, the Aegis Vortex System, utilizing its
patent platform and in-house expertise to address these life threatening medical
conditions.

         In December 1997, American Home Products Corporation ("AHP" or
"Strategic Alliance Partner") announced the sale of its subsidiary,
Sherwood-Davis & Geck, the operating company responsible for the sales,
marketing and manufacturing of the Angio-Seal device, to Tyco International,
Ltd. ("Tyco"). Under the terms of the sale, all of the Company's agreements with
AHP were transferred to Tyco's subsidiary, The Kendall Company ("Kendall").
Accordingly, Kendall replaced AHP as the Company's Strategic Alliance Partner in
March 1998, upon finalization of the sale. The Company's relationship with its
Strategic Alliance Partner has enabled it to obtain critical funding to research
and develop the Angio-Seal, conduct clinical trials and gain regulatory approval
in the U.S. and Europe. This relationship provides access for the Angio-Seal
Product Line to the major worldwide markets.

         The following discussion and analysis should be read in conjunction
with the Consolidated Financial Statements and the notes thereto contained
elsewhere in this report.


RESULTS OF OPERATIONS
FISCAL YEAR ENDED JUNE 30, 1998 COMPARED TO FISCAL YEAR ENDED JUNE 30, 1997
         Revenues for these periods consisted of net sales, research and
development revenue, milestone fees and royalty income. Revenues increased 43%
to $11.3 million in the year ended June 30, 1998 ("fiscal 1998") from $7.9
million in the year ended June 30, 1997 ("fiscal 1997"). Net sales of products
and research and development revenue both increased 28% from the prior year
while royalty income increased 752%. The increase in net sales was mainly
attributable to an increase in Angio-Seal components sold to the Company's
Strategic Alliance Partner, as a result of increased demand in the U.S. and
European markets, as well as the expansion of the Company's third-party business
with other collagen and polymer customers. Approximately 178,000 Angio-Seal
units were sold to end-users in fiscal year 1998 compared to 26,000 in fiscal
1997. The increase in royalty income represented Angio-Seal royalties from a
full year of U.S. sales compared to nine months of sales in fiscal 1997, a
significant increase in demand in the U.S. and European markets and an increase
in total royalty per unit resulting from the Patent Acquisition Agreement (see
Note 5 of the Financial Statements). The increase in research and development
revenue related to contract 


                                       19



<PAGE>   20


research and development, including clinical trials, from the Strategic 
Alliance Partner for additional sizes of and product enhancements to the
Angio-Seal Product Line. The $1.1 million milestone fee represented the final
milestone under the License Agreement and was earned by the Company upon receipt
of FDA approval in the first quarter of fiscal 1997.

         Cost of products sold increased 33% to $4.1 million in fiscal 1998 from
$3.1 million in fiscal 1997. This increase reflected greater net sales of
products offset by manufacturing inefficiencies realized in the start-up phase
of production for the new sizes of the Angio-Seal, the 6F and 10F, and new
biomaterials products during the fiscal year.

         Research and development expense, including regulatory and clinical
expenses, increased 18% to $5.5 million in fiscal 1998 from $4.7 million in
fiscal 1997. The Company expanded the development of additional Angio-Seal sizes
and biomaterials products, including resorbable polymers and collagen, and
increased clinical trial activity. In addition, the Company significantly
expanded its development in revascularization technology as it targets
commencement of clinical trials on the AVS in fiscal year 1999.

         Selling, general and administrative expense decreased 3%, or $61,000, 
in fiscal 1998 from fiscal 1997. This decrease was primarily due to a 
reduction in certain outside professional fees.

         Interest income decreased 14% to $540,000 in fiscal 1998 from $627,000
in fiscal 1997. The decrease was primarily attributable to cash equivalent and
investment balances in the first quarter of fiscal 1997, which included funds
used in the repayment of the Credit Agreement. Total cash and investment
balances have remained relatively constant since that time. Interest expense
decreased 22% to $150,000 for fiscal 1998 from $193,000 for fiscal 1997. This
decrease is also a result of the repayment of the Credit Agreement in October
1996 offset by amounts drawn under the Company's line of credit during the
current fiscal year and interest charges recorded in relation to the obligation
under the Company's Patent Acquisition Agreement.

         During fiscal 1997, the Company received $1.3 million in final
settlement for the business interruption portion of their insurance claim
related to the roof collapse. Of this amount, $969,000 was recorded as other
income.

         Other non-operating income decreased 47% from $8,000 in fiscal 1997 to
$4,000 in fiscal 1998. Fiscal 1997 other non-operating income represented
primarily a net gain on the sale of fixed assets while fiscal 1998 represented
miscellaneous nonrecurring items.


FISCAL YEAR ENDED JUNE 30, 1997 COMPARED TO FISCAL YEAR ENDED JUNE 30, 1996
         Revenues for these periods consisted of net sales, research and
development revenue, milestone fees and royalty income. Revenues increased 167%
to $7.9 million in fiscal 1997 from $3.0 million in fiscal 1996. Net sales of
products increased 178% while research and development revenue increased 80% and
royalty income increased 363%. The increase in net sales was mainly attributable
to increases in resorbable component and subassembly sales to the Company's
Strategic Alliance Partner to support increased demand in the European market
and the launch of the 8F Angio-Seal product in the U.S. following FDA approval
in September 1996. The increase in research and development revenue related to
contract research and development, including clinical trials, from the Strategic
Alliance Partner for additional sizes of and product enhancements to the
Angio-Seal. The $1.1 million milestone fee represented the final milestone under
the License Agreement and was earned by the Company upon receipt of FDA approval
in the first quarter of fiscal 1997. The increase in royalty income represented
Angio-Seal royalties from a full year of European sales and the commencement of
U.S. sales compared to only nine months of European sales in fiscal 1996.

         Cost of products sold increased 87% to $3.1 million in fiscal 1997 from
$1.6 million in fiscal 1996. The fiscal 1997 cost of products sold represented a
16% gross profit margin, a change in trend from a 24% 


                                       20



<PAGE>   21

negative gross profit margin in fiscal 1996. This favorable trend resulted from 
manufacturing efficiencies realized as production levels increased.

         Research and development expense increased 31% to $4.7 million in
fiscal 1997 from $3.6 million in fiscal 1996. The Company expanded the
development of additional Angio-Seal sizes and biomaterials products, including
resorbable polymers and collagen, increased clinical trial activity and
continued development of its revascularization technology. Six additional
research and development employees were hired in fiscal 1997 as part of the
increased activity. Accordingly, research and development expenses as well as
related personnel costs increased in fiscal 1997.

         Selling, general and administrative expense decreased 15% to $1.8
million in fiscal 1997 from $2.1 million in fiscal 1996. This decrease was
primarily due to the final recording of deferred compensation expense for
nonofficers and directors during fiscal 1996 to reflect settlement of certain
employee stock rights at the IPO.

         Deferred compensation expense, officers and directors in fiscal 1996
represented the final recording of deferred compensation in December 1995 to
reflect settlement of certain employee stock rights in the IPO.

         The product return charge of $574,000 in fiscal 1996 was due to the
withdrawal of two production lots, and subsequent inventory, as a result of
internal routine testing. This issue was resolved and there has been no further
impact of such withdrawal on the results of operations of the Company.

         Interest income increased 30% to $627,000 in fiscal 1997 from $483,000
in fiscal 1996. The increase represented the interest earned on the cash
equivalent and investment balances remaining from the IPO which were held for an
entire year in fiscal 1997 compared to only six months in fiscal 1996. Interest
expense decreased 80% to $193,000 for fiscal 1997 from $956,000 for fiscal 1996.
This decrease is a result of the repayment of the Credit Agreement with the
Company's Strategic Alliance Partner upon receipt of FDA approval of the
Angio-Seal in September 1996. The remaining interest expense represented
interest on a $100,000 bank line of credit entered into in October 1996 and
increased to $500,000 in February 1997.

         During fiscal 1997, the Company received $1.3 million as final
settlement for the business interruption portion of its insurance claim related
to the roof collapse. Of this amount, $288,000 had been recorded as a receivable
in fiscal 1996 and the remainder, net of adjuster fees, was recorded as a
component of other income in fiscal 1997. The Company received $1.2 million in
final settlement of the property damage portion of the insurance claim in fiscal
1996, of which $946,000 was recorded as a component of other income.

         In fiscal 1997, the majority of the total other non-operating income of
$8,000 represented a net gain on the sale of fixed assets. In fiscal 1996, the
Company had other non-operating income of $62,000, resulting from non-recurring
items.

LIQUIDITY AND CAPITAL RESOURCES
         The Company has financed its operations since inception through the
sale of equity securities, licensing of technology, research and development
arrangements, debt and credit arrangements and product sales.

         The Company generated cash from operations of $6,000 during fiscal 1998
compared to the cash flow from operations in fiscal 1997 of $2.9 million. This
change is primarily due to the $3.0 million royalty advance received under the
License Agreement upon receipt of FDA approval of the Angio-Seal in fiscal 1997.
This royalty advance was reduced throughout fiscal 1998 as the Company exceeded
minimum royalty stipulations under the Licensing Agreement. In addition, the
Company had income from operations of $343,000 in fiscal 1998 compared to a loss
from operations in fiscal 1997 of $262,000.

                                        
                                       21



<PAGE>   22

         Capital expenditures were $1.8 million in fiscal 1998 which represented
primarily leasehold improvements and machinery and equipment related to the
continued expansion of the Company's manufacturing capabilities principally
related to its collagen and polymer product lines. Capital expenditures were
funded essentially through the Company's line of credit under which the Company
borrowed $1.5 million in fiscal 1998.

         The Company's cash, cash equivalents and short-term investments were
$7.8 million at June 30, 1998. In addition, the Company has pledged $1.9 million
in investments (not included in the $7.8 million) as collateral to secure bank
loans made to certain employees for the payment of taxes incurred by such
employees as a result of their receipt of common stock at the time of the IPO.
In exchange for the Company's pledging this collateral, the employees have
pledged their common stock as collateral to the Company.

         In October 1996, the Company paid $6.5 million in full settlement of
the Credit Agreement with its Strategic Alliance Partner. Also, during fiscal
1997, the Company received $500,000 under a bank line of credit. At June 30,
1997 the $500,000 remained outstanding accruing interest, payable monthly, at
the prime rate (8.5% at June 30, 1997). The line of credit was increased from a
$500,000 facility to a $2.0 million facility in September 1997 and converts to a
term loan payable in 60 equal installments beginning August 1, 1998.

         In November 1997, the Company acquired patents under a Patent
Acquisition Agreement in exchange for 200,000 shares of common stock and a
series of eight quarterly cash payments, beginning on March 31, 1998, totaling
$1.2 million. The patents have been recorded on the balance sheet at the value
of the shares on the date of the agreement plus the present value of the $1.2
million cash and any legal and other related costs incurred to acquire such
patents. The present value of the cash payments ($1.1 million) was recorded
between short and long-term liabilities at December 31, 1997 and reduced to
$879,000 upon payment of the second installment on June 30, 1998.

         The Company plans to continue to expend substantial resources in
funding clinical trials to gain regulatory approvals and make additional
marketing claims as well as to expand research and development activities for
the Angio-Seal, revascularization technology and biomaterials products.

         The Company believes cash generated from operations as well as funds
available under financing arrangements with its bank will be sufficient to meet
the Company's operating and capital requirements for the next twelve months.

YEAR 2000 COMPLIANCE
         The Company began work on the computer Year 2000 issue in fiscal year
1998 and expects to complete its efforts by the end of fiscal year 1999.
Software applications, hardware and related technologies have been, or are in
the process of being, upgraded or replaced to ensure that all systems are Year
2000 compliant. Replacing hardware or software in this fashion is considered a
normal cost of doing business and is being expensed or capitalized as
appropriate. The Company is also working with its significant suppliers and
customers to address any impact of their Year 2000 issues on the Company. The
Company does not warrant, however, that these companies' year 2000 compliance
activities will be completely successful. Management does not anticipate that
the costs of year 2000 compliance will have a material effect on the Company's
results of operations, cash flows, or financial position.

         The Company anticipates that its results of operations will fluctuate
for the foreseeable future due to a number of factors. Such factors include the
Company's Strategic Alliance Partner's performance in the marketing,
manufacturing and distribution of the Angio-Seal Product Line, the timing of
future regulatory approvals in the United States and in countries outside of
Europe including Japan, the results of ongoing and planned clinical trials for
the Angio-Seal and other products, the acceptance of the Company's products in
the marketplace and competitive products generally and in particular those
designed for the sealing of arterial site punctures.

INDEPENDENT AUDITORS' REPORT

         To the Board of Directors and Shareholders of
                  Kensey Nash Corporation:

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

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

         In our opinion, such consolidated financial statements present fairly,
         in all material respects, the financial position of Kensey Nash
         Corporation as of June 30, 1998 and 1997, and the results of its
         operations and its cash flows for each of the three years in the period
         ended June 30, 1998 in conformity with generally accepted accounting
         principles.

KENSEY NASH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED JUNE 30, 1998, 1997 AND 1996
- --------------------------------------------------------------------------------

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BUSINESS - Kensey Nash Corporation (the "Company") designs, develops and
      manufactures, both individually and in conjunction with third parties,
      medical devices for use primarily in the cardiovascular and orthopedic
      markets. The Company's primary product, the Angio-Seal, is an absorbable
      medical device for the sealing of arterial punctures created during
      cardiovascular procedures such as angiography, angioplasty, atherectomy
      and the placement of stents. The Company was incorporated in Delaware on
      August 6, 1984.

      PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION - The consolidated
      financial statements include the accounts of Kensey Nash Corporation and
      Kensey Nash Holding Company. All intercompany transactions and balances
      have been eliminated. Kensey Nash Holding Company, incorporated in
      Delaware on January 8, 1992, was formed to hold title to certain Company
      patents and has no operations.

      The preparation of the consolidated financial statements in conformity
      with generally accepted accounting principles necessarily requires
      management to make estimates and assumptions. These estimates and
      assumptions, which may differ from actual results, will affect the
      reported amounts of assets and liabilities and disclosure of contingent
      assets and liabilities at the date of the financial statements, as well as
      the reported amounts of revenue and expense during the period.

      CASH AND CASH EQUIVALENTS - Cash and cash equivalents represent cash in
      banks and short-term investments having an original maturity of less than
      three months.

      FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying amounts of financial
      instruments including cash and cash equivalents, short-term investments,
      accounts receivable, accounts payable and debt approximated fair value as
      of June 30, 1998 and 1997. The fair value of short-term investments is
      based on quoted market prices.

      INVESTMENTS - Investments at June 30, 1998 consist of short-term
      Certificates of Deposit, Government Bonds and U.S. Treasury Bills. In
      accordance with Statement of Financial Accounting Standards ("SFAS") No.
      115, Accounting for Certain Investments in Debt and Equity Securities, the
      Company has classified its entire investment portfolio as
      available-for-sale securities, except for those pledged as collateral
      which are included as restricted investments (see Note 9).
      Available-for-sale securities are reported at fair value with unrealized
      gains and losses included in stockholders' equity (at June 30, 1998,
      amortized cost approximates fair value). Realized gains and losses are
      included in interest income.

      INVENTORY - Inventory is stated at the lower of cost (determined by the
      average cost method which approximates first-in, first-out) or market.
      Inventory primarily includes the cost of material utilized in the
      processing of the Company's products and is as follows:

<PAGE>   31

      PROPERTY, PLANT AND EQUIPMENT - Property, plant and equipment consists
      primarily of machinery and equipment and leasehold improvements and is
      recorded at cost. Maintenance and repairs are expensed as incurred.
      Machinery, furniture and equipment is depreciated using the straight-line
      method over its useful life ranging from five to seven years. Leasehold
      improvements are amortized using the straight-line method over the lesser
      of the term of the lease or useful life of the asset.

      IMPAIRMENT OF LONG-LIVED ASSETS - Long-lived assets are reviewed for
      impairment whenever events or circumstances indicate that the carrying
      amount of an asset may not be recoverable. If the undiscounted expected
      future cash flows to be generated by the related asset are less than the
      carrying value of the asset, the Company measures the amount of the
      impairment by comparing the carrying amount of the asset to its fair
      value. The estimation of fair value is generally measured by discounting
      expected future cash flows at the rate the Company borrows.

      PATENTS - The costs of internally developed patents are expensed when
      incurred due to the long development cycle for patents and the Company's
      inability to measure the recoverability of these costs when incurred. The
      cost of acquired patents is being amortized over the remaining period of
      economic benefit, ranging from 15 to 16 years at June 30, 1998.

      REVENUE RECOGNITION - Revenue under research and development contracts is
      recognized as the related costs are incurred; licensing fees and milestone
      payments under the Strategic Alliance Agreements (see Note 2) are
      recognized when the earnings process is complete; and revenue for sales is
      recognized when the related product is shipped.

      EXPORT SALES - Export sales from the Company's U.S. operations to
      unaffiliated customers in Europe totaled $72,035, $1,637,583 and $867,542
      for the years ended June 30, 1998, 1997 and 1996, respectively.

      INCOME TAXES - The Company accounts for income taxes under the provisions 
      of SFAS No. 109, Accounting for Income Taxes. (See Note 8).

      INITIAL PUBLIC OFFERING - On December 13, 1995 the Company sold 2.7
      million shares of Common Stock in an initial public offering (the "IPO").
      The net proceeds from the IPO (approximately $29.1 million) have been and
      will continue to be used primarily for research and development, including
      clinical trials; expansion of the Company's manufacturing capabilities;
      repayment of certain indebtedness; and working capital and general
      corporate purposes.

      A charge of approximately $1.2 million was recorded in the year ended June
      30, 1996 resulting from the settlement of the Company's Employee Stock
      Rights (see Note 13). In conjunction therewith, 456,493 shares of Common
      Stock were issued to settle the awards above and certain notes receivable.

      EARNINGS PER SHARE - Effective for 1998, earnings per share are calculated
      in accordance with SFAS No. 128, Earnings per Share which requires the
      Company to report both basic and diluted earnings per share ("EPS"). Basic
      and diluted EPS are computed using the weighted average number of shares
      of common stock outstanding, with common equivalent shares from options
      included in the diluted computation when their effect is dilutive. All
      previously disclosed earnings per share data have been recalculated to
      reflect the provisions of SFAS No. 128 (see Note 16).

      For the year ended June 30, 1996, the weighted average common shares
      outstanding has been increased by 446,437 shares, which is the number of
      common stock equivalents issued within one year of the IPO with exercise
      prices below the IPO price.

      STOCK-BASED COMPENSATION - Stock-based compensation cost is accounted for
      under SFAS No. 123, Accounting for Stock-Based Compensation, which permits
      continued application of the intrinsic value method of Accounting
      Principles Board Opinion No. 25, Accounting for Stock Issued to Employees.
      Under the intrinsic value method, compensation cost represents the excess,
      if any, of the quoted market price of the Company's common stock at the
      grant date over the amount the grantee must pay for the 


                                       31
<PAGE>   32

      stock. The Company's policy is to grant stock options at the fair market
      value at the date of grant (see Note 15).

      NEW ACCOUNTING PRONOUNCEMENTS - In June 1997, the Financial Accounting
      Standards Board ("FASB") issued SFAS No. 130, Reporting Comprehensive
      Income, which establishes standards for reporting and classifying
      components of comprehensive income in the financial statements. In June
      1997, the FASB also issued SFAS No. 131, Disclosures about Segments of an
      Enterprise and Related Information. This statement establishes standards
      for providing disclosures related to products and services, geographic
      area and major customers. The Company will adopt these statements in its
      fiscal year 1999 financial statements as required. Implementation of these
      standards is not expected to have a material effect on the Company's
      financial statements, but may require additional financial statement
      disclosures.

       PRESENTATION - Certain items in the 1997 and 1996 consolidated financial
      statements have been reclassified to conform with the presentation in the
      1998 consolidated financial statements.

2.    STRATEGIC ALLIANCE AGREEMENTS

      The Company had entered into a strategic alliance with American Home
      Products ("AHP" or "Strategic Alliance Partner") which incorporated United
      States and foreign license agreements (together, the "License
      Agreements"), a research and development agreement, a collagen supply
      agreement and a credit agreement (see Note 6) (collectively, the
      "Strategic Alliance Agreements"). In December 1997, AHP announced the sale
      of its subsidiary Sherwood, Davis & Geck ("SD&G"), the operating company
      responsible for sales, marketing and manufacturing of the Angio-Seal
      device, to Tyco International Ltd. ("Tyco"). Under the terms of the sale,
      the Company's Strategic Alliance Agreements with AHP were transferred to
      Tyco's subsidiary, The Kendall Company ("Kendall"). Accordingly, Kendall
      replaced AHP as the Company's Strategic Alliance Partner in March 1998,
      upon finalization of the sale.

      THE LICENSE AGREEMENTS - On September 4, 1991, the Company entered into
      the License Agreements with its Strategic Alliance Partner to develop the
      Angio-Seal. Under the provisions of these agreements, both parties are
      responsible for the further development of the product and the Strategic
      Alliance Partner has exclusive rights to manufacture and market all
      current and future sizes of the Angio-Seal worldwide.

      Under the License Agreements, the Company receives royalty payments based
      upon a percentage of the revenues generated from the sale of the
      Angio-Seal. The License Agreements also provide for certain minimum
      royalty payments ("Minimum Royalty") during the first five years after
      receiving U.S. Food and Drug Administration ("FDA") approval.

      The Company has received "licensing and milestone fees," totaling $11.0
      million, as set forth in the License Agreements. The final milestone
      payment of $1.05 million was received upon the pre-market approval by the
      FDA to produce and market the Angio-Seal in the United States on September
      30, 1996. In addition, a $3.0 million advance was received on future
      royalties, which, as stipulated in the License Agreements, will be reduced
      in each royalty year (the period beginning on October 1st and ending on
      September 30th) by 50% of royalties earned in excess of the Minimum
      Royalty in that year. The remainder of royalties earned will be received
      as cash proceeds by the Company. At June 30, 1998, the Company had
      exceeded the first and second royalty year (periods ended September 30,
      1997 and September 30, 1998) Minimum Royalties by $352,310 and $1,688,530,
      respectively. The deferred revenue balance has been reduced by 50% of such
      total excess, to $1,979,580. As the Company cannot reasonably estimate the
      excess, if any, of future royalty payments over the Minimum Royalty in
      each year, the entire balance has been classified as long-term at June 30,
      1998.


                                       32



<PAGE>   33

      AHP also provided the Company with operating advances which were repaid
      with the proceeds of the IPO in the year ended June 30, 1996.

      THE RESEARCH AND DEVELOPMENT AGREEMENT - The Company and its Strategic
      Alliance Partner have an agreement whereby such partner funds certain
      ongoing research and development costs incurred by the Company. The
      Company contributes one-third of such research and development costs while
      the Strategic Alliance Partner contributes the remaining two-thirds. Prior
      to the IPO, the Strategic Alliance Partner funded the Company's portion of
      such costs. Such amounts were repaid with proceeds from the IPO and the
      Company has taken no further advances from such partner.

      THE COLLAGEN SUPPLY AGREEMENT - Pursuant to an agreement with the
      Strategic Alliance Partner, the Company manufactures collagen to be used
      in the Angio-Seal. The agreement contains a minimum purchase requirement
      from the Company for five years beginning May 31, 1995.

3.    RELATED PARTY TRANSACTIONS

      The Company earned interest income of $9,322 for the fiscal year ended
      June 30, 1996 on certain notes receivable from a former officer of the
      Company which was repaid at the date of the IPO. Such amount had been
      classified as a component of stockholders' equity as it was collateralized
      primarily by common stock and common stock equivalents.

      For the fiscal year ended June 30, 1996, the Company incurred $785,524    
      (of which $496,580 was offset against proceeds of the IPO) in legal fees
      with a law firm which serves as the Company's general counsel for all
      corporate legal affairs. Certain current and former partners of such firm
      had interests in an investment partnership that owned 50,000 shares of
      the outstanding Common Stock of the Company. The shares were sold during
      the fiscal year ended June 30, 1997.

      See Note 13 for a discussion of related party transactions with certain
      former officers and transactions related to employee stock rights issued
      to current and former officers and an outside director.

4.    LEASES

      non-cancelable lease obligations are as follows:

      Such assets are amortized over periods ranging from three to five years,
      which represent the lesser of the term of the lease or useful life of the
      asset.

      The majority of rent expense is for the Company's facility in Exton,
      Pennsylvania. The Company also has various office and manufacturing
      equipment operating leases. Rent expense for the fiscal years ended June
      30, 1998, 1997 and 1996 was approximately $326,000, $275,000 and $279,000,
      respectively.

5.    PATENT ACQUISITION AGREEMENT

      On November 10, 1997, the Company entered into an agreement (the "Patent
      Acquisition Agreement") to acquire a portfolio of puncture closure patents
      and patent applications as well as the rights of the seller under a
      pre-existing licensing agreement. As a result of the Patent Acquisition
      Agreement, effective January 1, 1998, the Company is entitled to earn
      royalty fees, formerly paid to the sellers, for each Angio-Seal device
      sold. These royalties are in addition to the royalties already earned by
      the Company under its own License Agreement with its Strategic Alliance
      Partner.

      Under the terms of the Patent Acquisition Agreement, the Company issued
      200,000 shares of common stock and will make cash payments totaling $1.2
      million for the transfer of ownership of the patents. The cash portion is
      payable in eight quarterly installments (four $125,000 payments followed
      by four $175,000 payments), beginning on March 31, 1998. Accordingly, the
      present value of the cash payments (discounted based upon the Company's
      available borrowing rate of 8.5%) was recorded as a liability on the
      Company's financial statements, with a remaining balance of $879,228 at
      June 30, 1998 (see Note 6). The acquired patents are valued at the share
      price on the date of the Patent Acquisition Agreement plus the present
      value of the cash payments and the legal and related costs incurred to
      acquire the patents.

6.    DEBT

      LINE OF CREDIT - In August 1997, the Company increased its $500,000
      revolving credit and term loan agreement (the "Revolver") to $2.0 million.
      The Revolver bears interest at the prime rate (8.5% at June 30, 1998) and
      calls for interest only payments until August 1, 1998 at which time it
      converts to a term loan due in 60 monthly installments of principal and
      interest. The Revolver is collateralized by a first security interest in
      the equipment purchased with the proceeds, as well as certain other large
      equipment of the Company. At June 30, 1998, the Company had borrowed $2.0
      million under the Revolver. Subsequent to year end, the Company refinanced
      $925,000 of the outstanding balance under the Revolver with a $5.0 million
      financing agreement with a bank (the "Bond Agreement") (see Note 18). The
      term date on the remaining $1,075,000 under the Revolver was extended to
      August 1, 1999 and the interest rate modified to 8.0%. Accordingly, all
      amounts due under the Revolver have been classified as long-term at June
      30, 1998.

      THE CREDIT AGREEMENT - The Company had a $5 million Credit Agreement with
      its Strategic Alliance Partner. The outstanding balance of $6,517,348,
      including interest of $1,517,348, was repaid in October 1996 following
      receipt of FDA approval on September 30, 1996.

      Amounts outstanding under the Company's Revolver and Patent Acquisition
      Agreement are shown in the following table.

      $400,000 and $400,000 for the years 1999 through 2003, respectively.

7.    RETIREMENT PLAN

      The Company has a 401(k) Salary Reduction Plan and Trust (the "401(k)
      Plan") in which all employees that are at least 21 years of age are
      eligible to participate. Contributions to the 401(k) Plan are made by
      employees through an employee salary reduction election. Company
      contributions are discretionary. The Company has not made any
      contributions to the 401(k) Plan to date.

8.    INCOME TAXES

      The Company accounts for income taxes under SFAS No. 109, which generally
      provides that deferred tax assets and liabilities be recognized for
      temporary differences between the financial reporting basis and the tax
      basis of the Company's assets and liabilities and expected benefits of
      utilizing net operating loss ("NOL") carryforwards. The impact on deferred
      taxes of changes in tax rates and laws, if any, applied to the years
      during which temporary differences are expected to be settled are
      reflected in the financial statements in the period of enactment.

      For 1998 the Company has not provided for current income taxes due to the
      utilization of NOLs for tax purposes  The difference between the Company's
      income tax expense (benefit) and the income tax expense (benefit) computed
      using the U.S. federal income tax rate were as follows:

      The Company's entire deferred tax asset is offset by a valuation allowance
      due to the uncertainty surrounding future earnings. At June 30, 1998, the
      Company had NOL carryforwards for federal and state tax purposes totaling
      $18.0 and $2.8 million, respectively. A portion of the NOL may be subject
      to various statutory limitations as to its usage.

9.    COMMITMENTS AND CONTINGENCIES

      The Company has pledged $1,914,418 in investments as collateral to secure
      certain bank loans to employees which were used by such employees for the
      payment of taxes incurred as the result of the receipt of Common Stock in
      settlement of the Employee Stock Rights (see Note 13). In exchange for the
      Company pledging collateral for such loans, each affected employee has
      pledged their Common Stock as collateral to the Company. The balance
      outstanding on such employee loans was $1,818,697 at June 30, 1998.

10.   PRODUCT RETURN

      In January 1996, as a result of internal routine testing, the Company and
      AHP withdrew two production lots from sale in Europe, although neither the
      Company nor AHP had received any complaints concerning the product. After
      further testing on the withdrawn production lots, it was determined as a
      precautionary measure to withdraw the remaining inventory at AHP's
      European facility. In connection with this withdrawal, the Company
      recognized a pretax charge of $573,961 in its consolidated statements of
      operations during the year ended June 30, 1996. Corrective action was
      taken to resolve this issue, production resumed after the reconstruction
      of the damaged facility (see Note 11), and there was no further impact of
      such withdrawal on the consolidated financial statements of the Company.

11.   INSURANCE SETTLEMENT

      On January 8, 1996, the Company's facility sustained significant damage
      from a roof collapse resulting from a major snowstorm. The production of
      the Company's products was halted until the destroyed facilities could be
      reconstructed. Construction was completed in late March 1996 and
      production resumed at such time.

      The Company maintains both property damage and business interruption
      insurance. The Company recovered $1,186,619 (net of a $1,000 deductible)
      as final settlement for property damage in fiscal year 1996. Of the
      settlement amount, $240,629 represented reimbursable losses and expenses
      of the Company related to the facility damage. This amount and the
      remaining $945,990 are presented net in the selling, general and
      administrative ("S,G&A") expenses and as a separate component of other
      income, respectively, in the consolidated statement of operations for the
      year ended June 30, 1996.

      The Company also recovered $1,309,882 (net of a $1,000 deductible) as
      final settlement for business interruption in December 1996. Of this
      amount, $287,742 in continuing fixed payroll costs and related benefits
      incurred during the reconstruction period were offset against the related
      cost of products sold, SG&A expense and research and development expense
      in the consolidated statements of operations for the year ended June 30,
      1996 ($199,642, $29,073 and $59,027, respectively). The remaining $968,761
      (net of adjuster fees) has been recorded as a component of other income as
      a separate line item on the consolidated statement of operations for the
      year ended June 30, 1997.

12.   CONCENTRATION OF CREDIT RISK

      Financial instruments that potentially subject the Company to significant
      concentrations of credit risk consist primarily of cash and cash
      equivalents, short-term investments and accounts receivable. The Company
      places its cash, cash equivalents and short-term investments with high
      quality financial institutions and has established guidelines relative to
      diversification and maturities that maintain safety and high liquidity.
      With respect to trade and royalty receivables, such receivables are
      primarily with the Company's Strategic Alliance Partner (89% and 100% of
      trade and royalty receivables, respectively, at June 30, 1998) (see Note
      2). The Company performs ongoing credit evaluations on the 


                                       36

      remainder of its customers' financial conditions but does not require
      collateral to support customer receivables. For the years ended June 30,
      1998, 1997 and 1996, revenues from the Strategic Alliance Partner
      represented the following percentages of total revenues of the Company:

      employment agreements with certain of its officers which provide for
      aggregate annual base salaries of $730,000 through June 1999.

      EMPLOYEE STOCK RIGHTS - The Company had certain Stock Appreciation Plans,
      Phantom Stock Plans and Stock Award Obligations (together the "Employee
      Stock Rights") which were settled in full and the related plans canceled
      upon completion of the IPO.

      Under the Stock Appreciation Plans, 100,000 units, each equivalent to one
      share of common stock at a value of $8.00, had been awarded in the fiscal
      year ended June 1995 to former officers of the Company without cost. Upon
      closing of the IPO, the benefit paid to participants was 33,333 shares of
      common stock (equivalent to the excess of the offering price of $12 per
      share over the unit value of $8.00 per share). Related compensation
      expense of $400,000 was recorded for the year ended June 30, 1996.

      Under the Phantom Stock Plans, 439,478 units, each equivalent to one share
      of common stock, had been awarded to employees of the Company (including
      305,000 to current and former officers and directors). At the IPO,
      compensation expense of $2,082,518 related to these shares was recorded
      (of which $1,493,576 related to officers and directors.)

      Expense related to the issuance of previously granted stock awards to
      certain consultants of the Company (valued at $200,000), was recorded as a
      component of S,G&A expense for the year ended June 30, 1996.

14.   PREFERRED STOCK

      The Company has an authorized class of undesignated Preferred Stock
      consisting of 100,000 shares with a $.001 par value. The Board of
      Directors may authorize the issuance of Preferred Stock which ranks senior
      to the common stock with respect to the payment of dividends and the
      distribution of assets on liquidation. In addition, the Board of Directors
      is authorized to fix the limitations and restrictions, if any, upon the
      payment of dividends on Common Stock to be effective while any shares of
      Preferred Stock are outstanding. The Board of Directors, without
      stockholder approval, can issue Preferred Stock with voting and conversion
      rights which could adversely affect the voting power of the holders of
      Common Stock. At June 30, 1998 and 1997, no shares of Preferred Stock were
      outstanding. The Company has no present intention to issue shares of
      Preferred Stock.

15.   STOCK OPTION PLANS

      During 1995, the Company adopted the Employee Incentive Compensation Plan
      (the "Employee Plan"), a flexible plan that provides the Employee Plan
      Committee (the "Committee") broad discretion to award eligible
      participants with stock-based and performance-related incentives as the
      Committee deems appropriate. The persons eligible to participate in the
      Employee Plan are officers, employees and consultants of the Company who,
      in the opinion of the Committee, contribute to the growth and success of
      the Company.

      The Compensation Committee of the Board of Directors oversees the
      Committee and may grant nonqualified stock options, incentive stock
      options or a combination thereof to the participants. The Employee Plan
      provides for a total of 1.2 million shares available for option grants.
      Options granted will provide for the purchase of Common Stock at prices
      determined by the Compensation Committee, but in no event less than fair
      market value on the date of grant. As of June 30, 1998, awards consist
      solely of stock options as summarized in the table below.

      During 1995, the Company adopted the Nonemployee Directors' Stock Option
      Plan (the "Directors' Plan"). The Directors' Plan grants nonqualified
      stock options for the purchase of Common Stock to directors who are not
      employees. The Directors' Plan provides for a total number of 60,000
      shares available for option grants.

      The Directors' Plan provides for (i) the grant of an option to purchase
      5,000 shares of Common Stock to each participant on the Directors' Plan's
      effective date and (ii) a grant of an option to purchase 5,000 shares of
      Common Stock on the date of each regular annual stockholder meeting after
      the effective date to each participant upon such date and either is
      continuing as a nonemployee director subsequent to the meeting or who is
      elected at such meeting to serve as a nonemployee director. Options
      granted under the Directors' Plan must provide for the purchase of Common
      Stock at fair market value on the date of grant.

      Under both plans, the options are exercisable over a maximum term of ten
      years from the date of grant and vest over periods of zero to four years
      based on the grant date.

      A summary of the stock option activity under both plans for the years
      ended June 30, 1998, 1997 and 1996, is as follows:

18.   LITIGATION

      In March 1998, the Company, together with its Strategic Alliance Partner,
      filed a patent infringement claim against Perclose, Inc. of Menlo Park,
      California, ("Perclose"), a competitor in the puncture closure market.    
      The suit, filed in the Eastern District of Pennsylvania, claims that
      Perclose infringes the Company's U.S Patent No. 5,676,689 (the "Patent").
      The Patent covers a system and method for sealing a puncture in a blood
      vessel (e.g. the femoral artery). The Company seeks damages and an order
      to permanently enjoin Perclose from making, using or selling product that
      infringes the Patent.

      Perclose filed four counterclaims in answer to the complaint. The first
      counterclaim seeks to declare the Patent invalid and not infringed; the
      second and third counterclaims maintain that the Company committed
      antitrust violations; and the fourth counterclaim asserts that the Company
      committed unfair competition. Management is unable to predict the final
      outcome of the suit or whether the resolution of the matter could
      materially affect the Company's results of operations, cash flows, or
      financial position. Accordingly no amount has been recorded at June 30,
      1998 related to resolution of the Perclose matter.

19.   SUBSEQUENT EVENT

      Subsequent to year end, the Company entered into the Bond Agreement, an
      agreement backed by tax-exempt bonds issued by the local county
      development authority. The Bond Agreement bears interest at one percent
      above the five year Treasury Rate, adjusted quarterly. The Company
      refinanced $925,000 of the outstanding balance under the Revolver with a
      portion of the proceeds (see Note 6). The remaining $4,075,000 available
      under the Bond Agreement will be drawn by the Company for equipment
      purchases and facility expansion. The Bond Agreement calls for twenty-four
      monthly consecutive interest only payments followed by 60 monthly         
      installments of principal and interest and is collateralized by a first
      security interest in the equipment purchased with the proceeds, as well
      as a second security interest in the other assets of the Company.
