PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus.
This summary is not complete and may not contain all of the information that
investors should consider before investing in the common stock of Kensey Nash.
Investors should read the entire prospectus carefully.

OUR COMPANY

We have developed, or assisted in developing, and are manufacturing
resorbable biomaterials products for leading companies in the orthopedic,
cardiology, drug/biologics delivery and wound care markets for incorporation
into their products. We are also independently or on behalf of our customers
designing and developing various new resorbable biomaterials products for all of
these markets.

We are leaders in the development and manufacturing of cardiovascular
medical technology devices for arterial revascularization and arterial puncture
closure. We are developing the Aegis Vortex(TM) system, a device designed to
remove occlusive material from saphenous vein grafts implanted during coronary
bypass surgeries. We have completed a pilot clinical trial for the Aegis Vortex
and intend to commercialize the device. Additionally, we are the original
designers, developers and manufacturers of the Angio-Seal(TM), a leading product
in arterial puncture closure, which is manufactured, marketed and sold by St.
Jude Medical, Inc. This device is designed to seal and close femoral artery
punctures made during diagnostic and therapeutic cardiovascular
catheterizations.

OUR BIOMATERIALS TECHNOLOGY

Advances in biomaterials technology and a better understanding of the
biological processes involved in tissue formation and remodeling have led to the
introduction of resorbable biomaterials based products to address long-standing
deficiencies of traditional products and therapies. This trend has been observed
in many markets, including orthopedics, cardiology, drug/biologics delivery,
wound care, surgery, dentistry and urology. The technological challenges
involved in developing biomaterials products are substantial.

Through years of experience in biomaterials technology, we have addressed
these challenges and developed expertise in the use of collagen, polymers,
ceramics and other resorbable materials, as well as the processing of these
materials to make biomaterials products. We use this expertise to supply our
customers with complete solutions, including product design and engineering,
tool design, process development, commercial manufacturing and packaging
configuration. We believe that our biomaterials technology provides us with a
competitive advantage in that we are able to provide the essential building
blocks to develop biomaterials products.

OUR BIOMATERIALS STRATEGY

Our strategy is to expand our leadership position and expertise in
biomaterials products and technologies. The components of our strategy are as
follows:

- - Develop new proprietary biomaterials products. We are using our expertise in
resorbable biomaterials technology to develop new biomaterials products,
formulations and applications.

- - Expand our existing biomaterials business. We intend to aggressively expand
our existing biomaterials business by continuing to invest in new
manufacturing technologies and processes.

- - Commercialize biomaterials products. We are increasing the level of value we
add to the services and products we sell to our customers and believe we will
be able to increase our financial participation in the commercialization of
these services and products.

- - Pursue strategic acquisitions and alliances. We will seek strategic
acquisitions and alliances which add complementary technologies and expertise
in order to enhance our competitive position and broaden our intellectual
property portfolio.

<PAGE> 6

OUR BIOMATERIALS PRODUCTS

We currently provide our customers with proprietary biomaterials products
within the following markets:

- - Orthopedics: meniscal repair tacks, anterior cruciate ligament repair screws
and rotator cuff repair screws for use in sports medicine, repair plates,
screws and tacks for use in cranio-maxillofacial fixation and spinal fusion
resorbable growth factor delivery matrices for use in spinal fixation;

- - Cardiology: resorbable polymer anchors and collagen plugs for the Angio-Seal
for use in arterial puncture closure and vascular graft coatings;

- - Drug/Biologics Delivery: drug delivery matrices to treat cervical cancer and
dysplasia; and

- - Wound Care: collagen tissue engineering substrates used for culturing skin
cells to treat burns and skin defects and topical wound dressings.

We also have additional biomaterials products in development.

OUR CARDIOVASCULAR MEDICAL TECHNOLOGY BUSINESS

Aegis Vortex System

There are approximately 650,000 coronary bypass surgeries performed
annually and approximately half of all bypass grafts become diseased or occluded
within ten years of the surgery. Our Aegis Vortex System is designed to remove
occlusive material from saphenous vein grafts, thereby restoring blood flow to
the heart. The Aegis Vortex combines three key features to treat diseased
saphenous vein grafts: a high-speed rotating tip catheter, a distal protection
balloon and an extraction system. We believe the Aegis Vortex is the only
device, either in clinical trials or available commercially, which incorporates
all three of these features to address the diseased saphenous vein graft. We
have completed a pilot clinical trial and are pursuing commercialization of the
Aegis Vortex. The Aegis Vortex has not been approved by the FDA for marketing.

Angio-Seal

We are the original developers and manufacturers of the Angio-Seal device
which acts to seal and close femoral artery punctures made during diagnostic and
therapeutic cardiac catheterizations, such as angiograms, balloon angioplasties
and the placement of stents. There are approximately 6.5 million cardiac
catheterization procedures performed annually. The Angio-Seal device is a leader
in this marketplace with over 770,000 devices sold to date. The device consists
of four components: a resorbable polymer anchor, a resorbable collagen plug, a
resorbable suture and a delivery system. St. Jude Medical currently
manufactures, markets and distributes the Angio-Seal under exclusive worldwide
license agreements. We receive a royalty on every Angio-Seal device sold.

RISK FACTORS

You should carefully consider the following risk factors, in addition to
the other information set forth in this prospectus, before purchasing shares of
common stock of Kensey Nash. Each of these risk factors could adversely affect
our business, operating results and financial condition, as well as adversely
affect the value of an investment in our common stock. This investment involves
a high degree of risk.

RISKS RELATED TO OUR BUSINESS

IF OUR BIOMATERIALS PRODUCTS ARE NOT SUCCESSFUL, OUR OPERATING RESULTS AND
BUSINESS MAY BE SUBSTANTIALLY IMPAIRED.

The success of our existing biomaterials products, as well as any we
develop in the future, depends on a variety of factors, including our ability to
continue to manufacture, sell and competitively price these products and the
acceptance of these products by the medical profession. In addition, we may be
required to obtain regulatory approval for any future biomaterials products. We
will require substantial additional funds to develop and market our biomaterials
products. We expect to fund the growth of our biomaterials business out of our
operating income and cannot guarantee that this operating income will be
sufficient to develop new biomaterials products. To date, we have relied on
strategic partners or customers to market and sell our biomaterials products. We
cannot assure you that we will commercialize our products successfully either
indirectly through strategic partners or directly through the development of a
sales force.

WE CANNOT ASSURE YOU THAT WE WILL BE ABLE TO OBTAIN THE NECESSARY
REGULATORY APPROVALS FOR THE AEGIS VORTEX.

We need to conduct additional human feasibility clinical trials for the
Aegis Vortex. The Aegis Vortex has not been approved for marketing by the FDA or
by any governmental entity outside of the United States. We will require
substantial additional funds to develop the product, conduct clinical trials and
gain the necessary regulatory approvals for the Aegis Vortex. Prior to granting
approval, the FDA may require clarification of information provided in our
regulatory submissions, more information or more clinical studies. If granted,
FDA approval may impose limitations on the uses for which our product may be
marketed or how our product may be marketed. Should we experience delays or be
unable to receive approval from the FDA, our operating results and business may
be substantially impaired.

A SUBSTANTIAL PORTION OF OUR REVENUES WILL CONTINUE TO COME FROM THE
ANGIO-SEAL WHICH IS MANUFACTURED, MARKETED AND DISTRIBUTED BY ST. JUDE
MEDICAL.

To date, a significant portion of our revenues have been derived from
Angio-Seal sales. Under our license agreements with St. Jude Medical, Angio-Seal
is manufactured, marketed and sold on a worldwide basis by St. Jude Medical. Two
of our significant sources of revenue for the future are expected to be sales of
collagen to St. Jude Medical for use in the Angio-Seal devices and royalty
income from the sale of the Angio-Seal product line. Beginning June 1, 2000, St.
Jude Medical will no longer be obligated to buy collagen from us. Furthermore,
we expect a reduction in our royalty rate, from 12% to 9%, during the second
quarter of fiscal year 2001 in accordance with our license agreements. Our
success with Angio-Seal depends in part on the time, effort and attention that
St. Jude Medical devotes to the Angio-Seal product line and on their success in
manufacturing, marketing and selling the Angio-Seal product line. Under the
terms of our agreements with St. Jude Medical, we have no control over the
pricing and marketing strategy for the Angio-Seal product line. In addition, we
depend on St. Jude Medical to successfully maintain levels of manufacturing
sufficient to meet anticipated demand, abide by applicable manufacturing
regulations and seek reimbursement approvals. St. Jude Medical can terminate our
arrangement at any time after September 30, 2001 for any reason upon 12 months
notice. There can be no assurance that St. Jude Medical will successfully pass
future inspections of its manufacturing facility or adequately perform its
manufacturing, marketing and selling duties. Any such failure by St. Jude
Medical may negatively impact Angio-Seal sales and therefore reduce our
royalties and impair our operating results and business.

7
<PAGE> 10

WE DEPEND ON OUR CUSTOMERS TO MARKET AND OBTAIN REGULATORY APPROVALS FOR
THEIR BIOMATERIALS PRODUCTS.

We depend on the efforts of our biomaterials customers in marketing their
products which include our biomaterials components. There can be no assurance
that our customers' end use products which include our biomaterials components
will be commercialized successfully by our customers or that our customers will
otherwise be able to compete effectively in their markets. If our customers fail
to commercialize their products, our operating results and business may be
substantially impaired.

IF WE RECEIVE FDA APPROVAL, WE MAY NOT BE SUCCESSFUL COMMERCIALIZING THE
AEGIS VORTEX.

If the Aegis Vortex clinical trials are completed successfully and we
obtain the necessary governmental approvals, we will need to commercialize the
product. We cannot assure you that we will be able to find a suitable partner
and/or develop and train our own sales force to sell and market the Aegis
Vortex. We do not have a sales and marketing force nor do we have any experience
hiring or training a sales and marketing force. We may not be able to establish
and maintain an internal sales and marketing force with technical expertise and
supporting distribution capabilities. If we are unable to successfully
commercialize the Aegis Vortex, our growth prospects will be diminished.

WE MAY BE REQUIRED TO DELAY, REDUCE OR ELIMINATE SOME OR ALL OF OUR EFFORTS
TO DEVELOP AND MARKET THE AEGIS VORTEX IF WE FAIL TO OBTAIN ADDITIONAL
FUNDING THAT MAY BE REQUIRED TO SATISFY OUR FUTURE CAPITAL NEEDS.

We plan to continue to spend substantial funds to develop and market the
Aegis Vortex. Our future liquidity and capital requirements will depend upon
numerous factors, including the progress and success of our clinical trials, the
timing and cost involved in obtaining regulatory approvals, the timing and cost
of developing sales and marketing strategies, our ability to enter into
strategic alliances, manufacturing and research and development activities, the
extent to which the Aegis Vortex gains market acceptance and competitive
developments. Any additional required financing may not be available on
satisfactory terms, if at all. If we are unable to obtain financing, we may be
required to delay, reduce or eliminate some or all of our research and
development activities or sales and marketing efforts, in which case our
operating results and business may be substantially impaired.

THE MARKETS FOR OUR PRODUCTS ARE HIGHLY COMPETITIVE AND ARE LIKELY TO
BECOME MORE COMPETITIVE, AND OUR COMPETITORS MAY BE ABLE TO RESPOND MORE
QUICKLY TO NEW OR EMERGING TECHNOLOGIES AND CHANGES IN CUSTOMER
REQUIREMENTS.

The existing markets for our current and proposed products are intensely
competitive. We expect competition to increase further as additional companies
begin to enter our markets and/or modify their existing products to compete
directly with ours. We compete with some of the largest players in the
biomaterials markets. If we are successful in commercializing the Aegis Vortex,
our competitors will include Boston Scientific Corporation, Johnson and Johnson,
Inc., Possis Medical, Inc., Percu-Surge Inc. and Interventional Technologies,
Inc., as well as other companies and other current and future therapies. The
primary competitors in the vascular sealing device market are Abbott
Laboratories (which owns Perclose, Inc.), Datascope Corp. and Vascular
Solutions, Inc.

Our competitors may have broad product lines which allow them to negotiate
exclusive, long-term supply contracts and offer comprehensive pricing for their
products. Broader product lines may also provide our competitors with a
significant advantage in marketing competing products to group purchasing
organizations and other managed care organizations that are increasingly seeking
to reduce costs through centralized purchasing. Greater financial resources and
product development capabilities may allow our competitors to respond more
quickly to new or emerging technologies and changes in customer requirements
that may render our products obsolete.

8
<PAGE> 11

Because a significant portion of our revenue depends on sales of medical
devices by our customers to the end user market, we are also affected by
competition within the markets for these devices. Competition within the medical
device market could also have an adverse effect on our business for a variety of
reasons, including that our customers may compete directly with larger, dominant
manufacturers with extensive product lines and greater sales, marketing and
distribution capabilities. We are also unable to control other factors that may
impact the commercialization of our components for end use products, such as
marketing and sales efforts and competitive pricing pressures within particular
markets.

IF OUR PRODUCTS ARE NOT ACCEPTED BY THE MEDICAL COMMUNITY, OUR BUSINESS MAY
SUFFER.

The success of our existing products depends on continued acceptance of
these products by the medical community. The success of any products we develop
in the future will depend on the adoption of these products by our targeted
markets. We cannot predict how quickly, if at all, the medical community will
accept our future products or the extent to which our future products will be
used. If we encounter difficulties introducing future products into our targeted
markets, our operating results and business may be substantially impaired.

THE LOSS OF, OR INTERRUPTION OF SUPPLY FROM, KEY VENDORS COULD LIMIT OUR
ABILITY TO MANUFACTURE OUR PRODUCTS.

We purchase certain materials and components for our products from various
suppliers. Some of these components are custom made for us. Any loss of, or
interruption of supply from, key vendors may require us to find new vendors. We
could experience production or development delays while we seek new vendors
which could substantially impair our operating results and business.

WE MAY HAVE PROBLEMS MANUFACTURING AND DELIVERING OUR BIOMATERIALS PRODUCTS
IN THE FUTURE.

The biomaterials industry is an emerging area, using many materials which
are untested or whose properties are still not known. Consequently, from time to
time we may experience unanticipated difficulties in manufacturing and
delivering our biomaterials products to our customers. These difficulties may
include an inability to meet customer demand, delays in delivering products or
quality control problems with certain biomaterials products. Any such difficulty
to fulfill orders on a timely basis could materially and adversely affect our
operating results and business.

OUR USE OF HAZARDOUS MATERIALS EXPOSES US TO THE RISK OF MATERIAL
ENVIRONMENTAL LIABILITIES.

Because we use hazardous substances in our research and development and
manufacturing operations, we are potentially subject to material liabilities
related to personal injuries or property damages that may be caused by hazardous
substance releases or exposures at or from our facility. Decontamination costs,
other clean-up costs and related damages or liabilities could substantially
impair our business and operating results. We are required to comply with
increasingly stringent laws and regulations governing environmental protection
and workplace safety, including requirements governing the handling, storage and
disposal of hazardous substances.

ST. JUDE MEDICAL'S INTERNATIONAL SALES ARE SUBJECT TO A NUMBER OF RISKS
THAT COULD HARM FUTURE INTERNATIONAL SALES OF ANGIO-SEAL AND THEIR ABILITY
TO SUCCESSFULLY COMMERCIALIZE NEW PRODUCTS IN INTERNATIONAL MARKETS.

St. Jude Medical sells the Angio-Seal product line internationally and pays
us a royalty on each unit sold. Our royalties are subject to several risks,
including:

- the impact of recessions in economies outside the United States;

- unexpected changes in regulatory requirements, tariffs or other trade
barriers;

- weaker intellectual property rights protection in some countries;

9
<PAGE> 12

- fluctuations in exchange rates;

- potentially adverse tax consequences; and

- political and economic instability.

The occurrence of any of these events could seriously harm St. Jude
Medical's future international sales and our ability to receive royalties from
sales of the Angio-Seal in international markets.

OUR SUCCESS DEPENDS ON KEY PERSONNEL, THE LOSS OF WHOM COULD IMPAIR OUR
OPERATING RESULTS AND BUSINESS.

Our success depends, to a significant extent, upon the efforts and
abilities of Joseph W. Kaufmann, Douglas G. Evans and other members of senior
management. The loss of the services of one or more of these key employees could
harm our operating results and business. In addition, we will not be successful
unless we can attract and retain skilled personnel, particularly in the areas of
research and product development.

OUR FAILURE TO EXPAND OUR MANAGEMENT SYSTEMS AND CONTROLS TO SUPPORT
ANTICIPATED GROWTH OR INTEGRATE FUTURE ACQUISITIONS COULD SERIOUSLY HARM
OUR OPERATING RESULTS AND BUSINESS.

Our operations continue to grow and we expect this expansion to continue as
we execute our business strategy. Sustaining our growth has placed significant
demands on management and our administrative, operational, information
technology, manufacturing, financial and personnel resources. Accordingly, our
future operating results will depend on the ability of our officers and other
key employees to continue to implement and improve our operational, client
support and financial control systems, and effectively expand, train and manage
our employee base. We may not be able to manage our growth successfully. This
inability to sustain or manage our growth could seriously harm our operating
results and business.

THE OWNERSHIP INTEREST OF OUR STOCKHOLDERS MAY BE DILUTED BY ANY FUTURE
ACQUISITIONS OR STRATEGIC ALLIANCES.

Our stockholders will depend upon the judgment of our management with
respect to any future acquisitions we make or strategic alliances we enter into.
Our management may decide to acquire other companies or finance strategic
alliances by issuing equity securities. As a result, you may experience dilution
of your ownership interest.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

IF WE ARE UNABLE TO PROTECT OUR PATENTS AND PROPRIETARY RIGHTS, OUR
REPUTATION AND COMPETITIVENESS IN THE MARKETPLACE MAY BE MATERIALLY
DAMAGED.

We regard our patents, biomaterials trade secrets and other intellectual
property as important to our success. We rely upon patent law, trade secret
protection, confidentiality agreements and license agreements with St. Jude
Medical to protect our proprietary rights. We have registered certain of our
patents with applicable governmental authorities. Effective patent protection
may not be available in every country in which our products are made available,
and we have not sought protection for our intellectual property in every country
where our products may be sold. There can be no assurance that the steps we take
to protect our proprietary rights will be adequate or that third parties will
not infringe or otherwise violate our patents or similar proprietary rights.

We and St. Jude Medical are plaintiffs in a patent infringement lawsuit
against Perclose, which was acquired by Abbott Laboratories, and we are
co-defendants against counterclaims filed by Perclose in response to our
complaint. We have spent substantial resources on this litigation. Intellectual
property litigation in recent years has proven to be very costly and complex,
and the outcome of such litigation is difficult to predict.

10
<PAGE> 13

WE MAY BE ACCUSED OF INFRINGING UPON THE PROPRIETARY RIGHTS OF OTHERS AND
ANY RELATED LITIGATION COULD MATERIALLY DAMAGE OUR OPERATING RESULTS AND
BUSINESS.

An adverse determination in any intellectual property litigation or
interference proceedings brought against us could prohibit us from selling our
products, subject us to significant liabilities to third parties or require us
to seek licenses from third parties. The costs associated with these license
arrangements may be substantial and could include ongoing royalties.
Furthermore, the necessary licenses may not be available to us on satisfactory
terms, if at all. Adverse determinations in a judicial or administrative
proceeding or failure to obtain necessary licenses could prevent us from
manufacturing and selling our products.

WE DO NOT OWN OR CONTROL THE USE OF THE ANGIO-SEAL TRADEMARK.

The term Angio-Seal is a trademark of St. Jude Medical. All goodwill
generated by the marketing and sales of devices bearing the Angio-Seal trademark
belongs to St. Jude Medical and not to us. Should the St. Jude Medical license
agreements terminate, we would not have the right to call any of our products
"Angio-Seal" unless we purchase or license the trademark from St. Jude Medical.
Without rights to the Angio-Seal trademark, we would have to market our products
under a different trademark. Moreover, upon the termination of the St. Jude
Medical license agreements, St. Jude Medical would have the right to compete
against us by selling collagen and puncture closure devices under the Angio-Seal
trademark. Thus, purchasers of puncture closure devices may be more likely to
recognize and purchase products labeled Angio-Seal regardless of whether those
devices originate from us.

RISKS RELATED TO OUR INDUSTRY

WE MAY FACE PRODUCT LIABILITY CLAIMS THAT COULD RESULT IN COSTLY LITIGATION
AND SIGNIFICANT LIABILITIES.

The manufacture and sale of medical products entail significant risk of
product liability claims. The medical device industry in general has been
subject to significant product liability litigation. Any product liability
claims, with or without merit, could result in costly litigation, reduced sales,
significant liabilities and diversion of our management's time, attention and
resources. We cannot be sure that our product liability insurance coverage is
adequate or that it will continue to be available to us on acceptable terms, if
at all.

WE FACE UNCERTAINTY RELATING TO THIRD PARTY REIMBURSEMENT FOR OUR PRODUCTS.

We could be seriously harmed by changes in reimbursement policies of
governmental or private healthcare payors, particularly to the extent any
changes affect reimbursement for catheterization procedures in which our
products are used. If physicians, hospitals and other users of our products fail
to obtain sufficient reimbursement from healthcare payors for procedures in
which our products are used or adverse changes occur in governmental and private
third-party payors' policies toward reimbursement for these procedures, our
operating results and business may be substantially impaired.

OUR PRODUCTS AND MANUFACTURING ACTIVITIES ARE SUBJECT TO EXTENSIVE
GOVERNMENTAL REGULATION THAT COULD MAKE IT MORE EXPENSIVE AND TIME
CONSUMING FOR US TO INTRODUCE NEW AND IMPROVED PRODUCTS.

Our products and manufacturing activities are subject to extensive
regulation by a number of governmental agencies, including the FDA and
comparable international agencies. We are required to:

- obtain the approval of the FDA and international agencies before we can
market and sell new products;

- satisfy these agencies' requirements for all of our labeling, sales and
promotional materials in connection with our existing products;

- comply with all applicable manufacturing regulations; and

- undergo rigorous inspections by these agencies.

11
<PAGE> 14

Compliance with the regulations of these agencies may delay or prevent us
from introducing any new or improved products, including the Aegis Vortex.
Furthermore, we may be subject to sanctions, including temporary or permanent
suspension of operations, product recalls and marketing restrictions if we fail
to comply with the laws and regulations pertaining to our business.

We are also required to demonstrate compliance with the FDA's quality
system regulations. The FDA enforces its quality system regulations through
pre-approval and periodic post-approval inspections. These regulations relate to
product testing, vendor qualification, design control and quality assurance, as
well as the maintenance of records and documentation. If we are unable to
conform to these regulations, we will be required to locate alternative
manufacturers that do conform. Identifying and qualifying alternative
manufacturers may be a long, costly and difficult process and could seriously
harm our business.

The FDA and international regulatory agencies may also limit the
indications for which our products are approved. These regulatory agencies may
restrict or withdraw approvals we have received if additional information
becomes available to support this action.

RISKS RELATED TO OUR OFFERING

CONCENTRATION OF OWNERSHIP IN OUR COMPANY MAY GIVE SOME STOCKHOLDERS
SUBSTANTIAL INFLUENCE AND MAY PREVENT OR DELAY A CHANGE IN CONTROL OF OUR
COMPANY.

We anticipate that our executive officers and directors, together with
their affiliates, will, in the aggregate, beneficially own approximately
3,391,131 shares, or 33.94%, of our outstanding common stock following the
completion of this offering, or approximately 3,191,131 shares, or 31.06% of our
common stock if the underwriters exercise their over-allotment options in full.
These stockholders may be able to exercise substantial influence over all
matters requiring stockholder approval, including the election of directors and
approval of significant corporate transactions. This concentration of ownership
may also have the effect of delaying or preventing a change in control of our
company.

OUR FUTURE OPERATING RESULTS ARE DIFFICULT TO PREDICT AND MAY VARY
SIGNIFICANTLY FROM QUARTER TO QUARTER.

Our operating results have varied significantly from quarter to quarter in
the past and are likely to vary substantially in the future as a result of a
number of factors, some of which are not in our control, including:

- market perception and customer acceptance of our products;

- market perception and acceptance of our customer's products;

- our efforts to increase sales of our biomaterials products;

- the loss of significant orders;

- changes in our relationship with St. Jude Medical;

- our establishment of strategic alliances or acquisitions;

- timely implementation of new and improved products;

- delays in obtaining regulatory approvals;

- increased competition; and

- litigation concerning intellectual property rights in the medical device
industry.

THE TRADING PRICE OF OUR COMMON STOCK IS LIKELY TO FLUCTUATE SUBSTANTIALLY
IN THE FUTURE.

The price of our common stock in this offering may not be indicative of the
prices that will prevail in the public market after this offering.

The trading price of our common stock may fluctuate widely as a result of a
number of factors, some of which are not in our control, including:

- quarter to quarter variations in our operating results;

- announcements regarding clinical activities or new products by us or our
competitors;

12
<PAGE> 15

- our announcements regarding the Aegis Vortex clinical trials;

- general conditions in the medical device industry;

- changes in earnings estimates by analysts; and

- price and volume fluctuations in the overall stock market, which have
particularly affected the market prices of many medical device companies.

In addition, the market for our stock has experienced extreme price and
volume fluctuations, which have often been unrelated to our operating
performance.

FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET BY STOCKHOLDERS WITH
SIGNIFICANT HOLDINGS COULD CAUSE OUR STOCK PRICE TO FALL.

Upon completion of the offering, we will have 9,992,488 outstanding shares
of common stock, assuming no exercise of outstanding options after May 1, 2000
and no exercise of the underwriters' over-allotment option. We will have
10,272,488 outstanding shares of common stock upon the completion of the
offering if the underwriters exercise their over-allotment option in full,
assuming no exercise of outstanding options after May 1, 2000.

Sales of a substantial number of shares of our common stock in the public
market following this offering or the perception that such sales could occur
could cause the market price of our common stock to decline or adversely affect
our future ability to raise capital through an offering of equity securities.
The number of shares of common stock available for sale in the public market is
limited by restrictions under federal securities law and under lock-up
agreements that our executive officers and directors have entered into with
Prudential Securities Incorporated. Under these lock-up agreements, our
executive officers and directors have agreed not to offer or sell any shares of
common stock for a period of 90 days after the date of this prospectus without
the prior written consent of Prudential Securities Incorporated. Kenneth R.
Kensey, M.D. and John E. Nash have entered into similar agreements for periods
of 180 days and one year, respectively. Virtually all of Dr. Kensey's shares are
subject to pledge agreements with third parties. These pledge agreements provide
that if the price of our common stock falls below certain levels, the pledged
shares could be sold by third parties into the public market. Prudential
Securities Incorporated may, at any time and without notice, waive any of the
terms of these lock-up agreements.

The following table indicates approximately when the shares of our common
stock that are subject to these lock-up agreements will be eligible for sale
into the public market, subject to Rule 144 of the Securities Act.

MANAGEMENT COULD SPEND OR INVEST OUR NET PROCEEDS OF THIS OFFERING IN WAYS
WHICH OUR STOCKHOLDERS MAY NOT AGREE, INCLUDING THE FINANCING OF ANY FUTURE
ACQUISITIONS OR ALLIANCES.

A substantial portion of the proceeds of our offering are not allocated for
specific purposes. Our management can spend or invest our net proceeds from this
offering in ways with which the stockholders may not agree. The investment of
these proceeds may not yield a favorable return. Our management may use a
portion of our net proceeds from this offering to finance any future
acquisitions we may make or alliances we enter into.

OUR SECOND AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND DELAWARE
LAW MAY DISCOURAGE AN ACQUISITION OF OUR COMPANY.

Provisions of our second amended and restated certificate of incorporation
and Delaware law could make it more difficult for a third party to acquire us,
even if doing so would be beneficial to our stockholders.

USE OF PROCEEDS

We will receive net proceeds of approximately $ million from the sale
of 2,500,000 shares of common stock by us in the offering, or $ million if
the underwriters exercise their over-allotment option from us in full, assuming
a public offering price of $ , after deducting underwriting discounts and
commissions and estimated offering expenses. We intend to use the net proceeds
as follows:

- approximately $15.0 million to continue to develop and conduct clinical
trials and complete regulatory submissions in the U.S. and
internationally for the Aegis Vortex;

- $6.1 million to repay outstanding debt comprised of a $1.1 million 8% per
annum term loan maturing January 1, 2005, and a $5.0 million loan with a
quarterly adjusted interest rate (which is currently 7.68%) maturing
January 1, 2006; and

- the remainder for general corporate purposes, including capital
expenditures and potential strategic acquisitions and alliances.

While we continue to evaluate potential strategic acquisitions and
alliances, we currently have no agreements regarding potential strategic
acquisitions or alliances. Our management has broad discretion over the use of
proceeds and may spend the net proceeds from this offering in ways with which
our stockholders may not agree. Pending use of the net proceeds of this
offering, we intend to invest them in short-term, interest-bearing,
investment-grade securities or guaranteed obligations of the U.S. government. We
will not receive any proceeds from the sale of shares of common stock by the
selling stockholders.

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

The following discussion and analysis should be read in conjunction with
"Selected Consolidated Financial Data" and our financial statements and the
related notes included in this prospectus. This discussion contains
forward-looking statements that involve risks and uncertainties. Our actual
results could differ materially from those anticipated in the forward-looking
statements as a result of various factors including the risks discussed in "Risk
Factors" and elsewhere in this prospectus.

OVERVIEW

We were founded in 1984 and our common stock became publicly traded in
December 1995. We have been profitable in each of our last ten fiscal quarters.

Revenues

Our revenues consist of three components: net sales, research and
development revenue and royalty income.

Net Sales. Net sales is comprised of resorbable biomaterials products and
Angio-Seal devices manufactured by us.

Biomaterials. The biomaterials component of net sales represents the
sale of our biomaterials products to customers for use in the following
markets: orthopedics, cardiology, drug/biologics delivery and wound care.
Historically, our biomaterials sales have represented primarily the
resorbable collagen and polymer components of the Angio-Seal device
supplied to St. Jude Medical. We have experienced significant sales growth
in our biomaterials products in fiscal years 1998, 1999 and 2000 due to
sales to new customers, increased sales to existing customers, new product
offerings and the expansion of our marketing activities. We believe this
growth will continue because of greater acceptance by the medical community
of biomaterials and technological advances which have expanded the
applications for our biomaterials products.

Angio-Seal Devices. Historically, we supplied our strategic partner
with partially completed 8F Angio-Seal devices. In fiscal year 1999 and
2000, we have supplied our partner with 6F Angio-Seal devices to supplement
their production requirements. We anticipate that St. Jude Medical will
transition the manufacturing of these devices to their facility by June 30,
2000.

Research and Development Revenue. Historically, research and development
revenue has been derived solely from development work performed on the
Angio-Seal. As anticipated, the research and development activities have
transitioned to St. Jude Medical and no additional research and development
revenue is expected.

Royalty Income. We receive a royalty on every Angio-Seal unit sold
worldwide. We anticipate sales of the Angio-Seal device will continue to grow,
particularly due to the recent launches of the 6F Angio-Seal in the U.S. and
Europe. As a result, royalty income will continue to be a significant source of
revenue. The anticipated increase in unit sales will be partially offset in the
fiscal year 2001 by an anticipated reduction in our royalty rate, from 12% to
9%, in accordance with our licensing agreements. We expect this rate reduction
will occur during the second quarter of fiscal year 2001.

Cost of Products Sold

We have experienced an overall increase in gross margin during the fiscal
year 2000 as our net sales have increased and we have been able to spread our
fixed costs of manufacturing over a greater number of units. We anticipate our
gross margin will continue to improve as our sales levels increase and our
product mix becomes more favorable, reflecting the shift to higher margin sales
of biomaterials products and a reduction in sales of lower margin Angio-Seal
devices.

18
<PAGE> 21

Research and Development Expense

Research and development expense consists of expenses incurred for the
development of our proprietary technology such as the Aegis Vortex, resorbable
biomaterials products and technologies and other development programs. While
research and development on the Angio-Seal has become an insignificant portion
of our overall development costs, the progression of the Aegis Vortex into the
clinical trial phase and our continued development of proprietary biomaterials
products and technologies will offset this decrease. We anticipate research and
development expense will continue to increase as we pursue commercialization of
the Aegis Vortex as well as explore opportunities for our other technologies.

Selling, General and Administrative

Selling, general and administrative expenses include general and
administrative costs as well as costs related to the marketing of our products.
During the fiscal years 1999 and 2000, the costs of our patent litigation are
also included within selling, general and administrative expenses. We anticipate
the marketing component of selling, general and administrative expenses, which
has been insignificant in past fiscal years, will increase as we evaluate
opportunities for commercialization of the Aegis Vortex and expand the marketing
efforts for our biomaterials business.

RESULTS OF OPERATIONS

COMPARISON OF NINE MONTHS ENDED MARCH 31, 1999 AND 2000

Revenues. Revenues increased 18% to $13.8 million in the nine months ended
March 31, 2000 from $11.6 million in the nine months ended March 31, 1999. Net
sales of products increased 82% to $9.1 million from $5.0 million for the nine
months ended March 31, 2000 and 1999, respectively. Of this increase, $2.5
million was attributable to an increase in sales of 6F Angio-Seal devices to St.
Jude Medical. The remaining $1.6 million was attributable to increased sales of
biomaterials products. We have been providing St. Jude Medical with 6F
Angio-Seal devices for the international and U.S. markets. We expect to continue
to supplement St. Jude Medical's manufacturing of these devices for the
remainder of fiscal year 2000.

Research and Development Revenues. Research and development revenues
decreased 97% to $48,000 from $1.6 million for the nine months ended March 31,
2000 and 1999, respectively. St. Jude Medical has transitioned substantially all
of the Angio-Seal research and development in-house. We do not expect research
and development revenues to be significant in the future.

Royalty Income. Royalty income increased 8%, net of a $750,000 supplemental
payment from our previous strategic partner in the nine months ended March 31,
1999, to $4.6 million from $4.3 million in the nine months ended March 31, 2000
and 1999, respectively. Royalty units increased as approximately 255,000
Angio-Seal units were sold to end-users during the nine months ended March 31,
2000 compared to approximately 227,000 units sold during the nine months ended
March 31, 1999. This unit increase was due to St. Jude Medical's increased sales
and marketing efforts primarily in the U.S. and sales of the new 6F device in
the international markets. The 6F device was introduced in the international
markets in April 1999 and in the U.S. in late March 2000.

Cost of Products Sold. Cost of products sold increased 37% to $5.1 million
in the nine months ended March 31, 2000 from $3.7 million in the nine months
ended March 31, 1999. However, gross margin increased to 44% from 26%. This
increase reflected an allocation of overhead across a greater sales volume,
which resulted in a decrease in per unit costs.

Research and Development Expense. Research and development expense
decreased 4% to $4.1 million in the nine months ended March 31, 2000 compared to
$4.3 million in the nine months ended March 31, 1999. This decrease was mainly
attributable to the transition of substantially all of the development for the
Angio-Seal product line to St. Jude Medical. This decrease was offset by our
continued development efforts on the Aegis Vortex, including clinical trial
expenses. We also continued to expand our development efforts on our
biomaterials products. We expect research and development

19
<PAGE> 22

expense to increase as we investigate and develop new products, conduct clinical
trials and seek regulatory approvals for our proprietary products.

Selling, General and Administrative. Selling, general and administrative
expense increased 8% to $2.0 million in the nine months ended March 31, 2000
from $1.9 million in the nine months ended March 31, 1999. This increase was
primarily the result of increased sales and marketing efforts for the Aegis
Vortex and our biomaterials products.

Net Interest Income. Interest expense increased 58% to $351,000 in the nine
months ended March 31, 2000 from $222,000 in the nine months ended March 31,
1999. This was due to the addition of a $5.0 million financing agreement in
January 1999, of which $925,000 was used to repay a portion of the $2.0 million
term loan. The remainder of the proceeds from the $5.0 million financing
agreement are being used to fund leasehold improvements and capital expansion.
Interest income increased 40% to $623,000 in the nine months ended March 31,
2000 from $444,000 in the nine months ended March 31, 1999 as a result of an
increase in average total cash and investment balances.

COMPARISON OF FISCAL 1998 AND 1999

Revenues. Revenues increased 44% to $16.2 million in the year ended June
30, 1999, or fiscal 1999, from $11.3 million in the year ended June 30, 1998, or
fiscal 1998. Net sales of products increased 54% to $7.2 million from $4.7
million. Of this, $2.5 million was attributable to increased sales of
biomaterials products comprised of $1.8 million of biomaterials products sold to
multiple customers and $700,000 of increased sales of Angio-Seal components to
St. Jude Medical. The remaining increase was attributable to the sale of 6F
Angio-Seal devices to St. Jude Medical for the international market.

Research and Development Revenue. Research and development revenue
decreased 48% to $1.9 million from $3.6 million. The decrease was due to a
reduction in Angio-Seal research and development activity as the 6F Angio-Seal
transitioned from development to commercialization.

Royalty Income. Royalty income increased 139% to $7.2 million from $3.0
million in fiscal 1999 and fiscal 1998, respectively. Of this increase, $2.7
million was due to increased unit sales of Angio-Seal. Approximately 310,000
Angio-Seal units were sold to end users in fiscal 1999 compared to approximately
178,000 units sold in fiscal 1998. The increase in Angio-Seal unit volume
reflected the launch of the 6F Angio-Seal in Europe in fiscal 1999 as well as
increased demand for the 8F Angio-Seal in both the U.S. and European markets in
fiscal 1999 versus fiscal 1998. In addition, we received a $1.5 million
supplemental royalty payment in fiscal 1999.

Cost of Products Sold. Cost of products sold increased 26% to $5.1 million
in fiscal 1999 from $4.1 million in fiscal 1998. However, the gross margin
increased to 28% from 13%. The increase in gross margin reflects an allocation
of overhead across greater sales volume, which results in a decrease in per unit
costs, as well as increased sales of higher margin biomaterials products.

Research and Development Expense. Research and development expense
increased 3% to $5.7 million in fiscal 1999 from $5.5 million in fiscal 1998.
This increase was mainly attributable to increased development efforts on the
Aegis Vortex as we applied for and received our investigational device
exemption, or IDE, from the FDA and prepared for the initiation of clinical
trials of the device. We also expanded our development efforts in the area of
resorbable biomaterials. These increases in expense were offset by the ongoing
transition of development of the Angio-Seal product line to St. Jude Medical
along with the 6F product moving to commercialization.

Selling, General and Administrative. Selling, general and administrative
expense increased 47% to $2.6 million in fiscal 1999 from $1.8 million in fiscal
1998. This increase was primarily a result of legal expenses in the amount of
$640,000 related to our ongoing patent infringement suit. We incurred no legal
expenses related to this lawsuit in fiscal 1998.

Net Interest Income. Interest expense increased 121% to $332,000 in fiscal
1999 from $150,000 in fiscal 1998. This increase was due to the addition of a
$5.0 million financing agreement in fiscal 1999, of

20
<PAGE> 23

which $925,000 was used to repay a portion of the existing $2.0 million term
loan. The remainder of the proceeds from the $5.0 million financing agreement
will be used to fund leasehold improvements and for capital expansion. Interest
income increased 20% to $649,000 in fiscal 1999 from $540,000 in fiscal 1998 as
a result of an increase in average total cash and investment balances.

Other Non-Operating Income. Other non-operating income remained constant
at $4,000 for fiscal 1999 and fiscal 1998. Fiscal 1999 other non-operating
income represented primarily a net gain on the sale of fixed assets while fiscal
1998 represented miscellaneous nonrecurring items.

COMPARISON OF FISCAL 1997 AND 1998

Revenues. Revenues increased 43% to $11.3 million in fiscal 1998 from $7.9
million in fiscal 1997. Net sales of products increased 28% to $4.7 million from
$3.6 million. Sales of Angio-Seal components to our partner increased $1.7
million as a result of increased demand for the Angio-Seal in the U.S. and
European markets. This increase was offset by a $900,000 decrease in sales of
complete Angio-Seal devices to our partner as they increased their manufacturing
capacity to meet increased market demands. In addition, biomaterials product
sales increased $200,000, as our business with third-party customers expanded.

Research and Development Revenue. Research and development revenue
increased 28% to $3.7 million in fiscal 1998 from $2.8 million in fiscal 1997.
The increase related to research and development, including clinical trials,
performed for our partner on the Angio-Seal product line.

Milestone Fees. The $1.1 million milestone fee represented the final
milestone under the license agreement with our strategic partner and was earned
by us upon receipt of FDA approval in the first quarter of fiscal 1997.

Royalty Income. Royalty income increased 752% to $3.0 million from
$353,000 in fiscal 1998 and fiscal 1997, respectively. Approximately 178,000
Angio-Seal units were sold by our partner to end users in fiscal year 1998
compared to approximately 26,000 in fiscal 1997. The increase in royalty income
represented a full year of 8F Angio-Seal U.S. unit sales in fiscal 1998 compared
to nine months of U.S. unit sales in fiscal 1997, a significant increase in
demand in the U.S. and European markets and a 3% increase in total royalty per
unit resulting from our acquisition of a third party's patents in November 1997.

Cost of Products Sold. Cost of products sold increased 33% to $4.1 million
in fiscal 1998 from $3.1 million in fiscal 1997 and our gross margin declined to
13% from 16%. The increase in cost of products sold reflected increased unit
sales. The reduction in gross margin was caused by manufacturing inefficiencies
realized in the start-up phase of production for the new sizes of the Angio-Seal
and new biomaterials products during the fiscal year.

Research and Development Expense. Research and development expense
increased 18% to $5.5 million in fiscal 1998 from $4.7 million in fiscal 1997.
We expanded the development of additional Angio-Seal sizes and biomaterials
products, including resorbable polymers and collagen, and increased clinical
trial activity. In addition, we significantly expanded our development on the
Aegis Vortex as we targeted commencement of clinical trials in fiscal year 1999.

Selling, General and Administrative. 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.

Net Interest Income. Interest expense decreased 22% to $150,000 for fiscal
1998 from $193,000 for fiscal 1997. This decrease resulted from the repayment of
a credit agreement with our partner in October 1996 offset by amounts drawn
under our bank line of credit during the current fiscal year and interest
charges recorded in relation to the obligation under our patent acquisition
agreement. Interest income decreased 14% to $540,000 in fiscal 1998 from
$627,000 in fiscal 1997. The decrease was primarily

21
<PAGE> 24

attributable to a decrease in cash, cash equivalent and investment balances in
the first quarter of fiscal 1997, representing funds used to repay our credit
agreement.

Insurance Settlement. During fiscal 1997, we received $1.3 million in
final settlement for the business interruption portion of our insurance claim
from our roof collapse in 1996. Of this amount, $969,000 was recorded as other
income.

Other Non-Operating Income. Other non-operating income decreased 47% from
$8,375 in fiscal 1997 to $4,405 in fiscal 1998. Fiscal 1998 represented
miscellaneous nonrecurring items while fiscal 1997 represented primarily a net
gain on the sale of fixed assets.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by our operating activities was $78,000 and $935,000
during the nine months ended March 31, 2000 and 1999, respectively. In the nine
months ending March 31, 2000, changes in asset and liability balances resulted
in a net $3.9 million use of cash, offset by net income of $2.8 million and non-
cash depreciation and amortization of $1.1 million. Changes in asset and
liability balances resulted in a net $2.0 million use of cash, offset by net
income of $2.0 million and non-cash depreciation and amortization of $914,000,
in the nine months ending March 31, 1999.

Our cash, cash equivalents and short-term investments were $9.0 million at
March 31, 2000. In addition, we have $2.5 million in restricted investment
accounts. We have pledged $1.9 million in investments as collateral to secure
bank loans made to employees to pay taxes incurred by these employees when they
received common stock at the time of our initial public offering. In exchange
for our pledging this collateral, the employees have pledged their common stock
to us as collateral. We also have $507,000 in investments restricted for capital
spending through June 30, 2000 under the terms of an agreement which provided a
total of $5.0 million. Related to this financing agreement, we have a capital
spending plan for fiscal year 2000 of which, for the nine months ended March 31,
2000, $2.2 million was expended primarily on machinery, equipment and leasehold
improvements. These expenditures were related to the continued expansion of our
manufacturing capabilities, principally for our biomaterials product lines.

We received a $3.0 million royalty advance under our licensing agreement
upon receipt of FDA approval for the Angio-Seal in fiscal year 1997. This
royalty advance has been reduced in each period by 50% of the excess of royalty
income over minimum royalties stipulated within the licensing agreement. During
the nine months ended March 31, 2000, the liability was retired.

In November 1997, we acquired patents in exchange for 200,000 shares of
common stock and a series of eight quarterly cash payments, which began on March
31, 1998, totaling $1.2 million. The patents were 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 the legal and other related costs incurred to
acquire such patents. The present value of the cash payments was $1.1 million
and was recorded on the balance sheet as an obligation. The obligation was fully
repaid during the nine months ended March 31, 2000.

We plan to continue to spend substantial amounts to fund clinical trials,
to gain regulatory approvals and to continue to expand research and development
activities, particularly for the Aegis Vortex and our biomaterials products. We
believe cash generated from operations will be sufficient to meet our operating
and capital requirements for the next twelve months.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our interest income and expense are sensitive to changes in the general
level of interest rates. In this regard, changes in interest rates affect the
interest earned on our cash, cash equivalents and investments as well as
interest paid on our debt.

Our investment portfolio consists primarily of high quality U.S. government
securities and certificates of deposit with an average maturity of one year or
less. We mitigate default risk by investing in what we believe are the safest
and highest credit quality securities and by monitoring the credit rating of
investment

22
<PAGE> 25

issuers. The portfolio includes only marketable securities with active secondary
or resale markets to ensure portfolio liquidity and there are limitations
regarding duration of investments. These available-for-sale securities are
subject to interest rate risk and decrease in market value if interest rates
increase. At March 31, 2000, our total portfolio consisted of approximately
$11.5 million of investments, all of which had maturities within one year.
Additionally, we generally hold securities until maturity. Therefore, we do not
expect our results of operations or cash flows to be materially impacted due to
a sudden change in interest rates. We have $1.1 million in fixed rate debt, for
which the risk would be an inability to refinance if rates decreased. The
remaining $5.0 million of our debt fluctuates with the U.S. treasury rate and is
therefore subject to increases in U.S. interest rates. The estimated potential
reduction in earnings from a one-point increase in the Five Year U.S. treasury
rate for the nine months ended March 31, 2000 would have been approximately
$37,500.

BUSINESS

OVERVIEW

We are experts in designing, developing, manufacturing and processing
proprietary biomaterials products for the orthopedics, cardiology,
drug/biologics delivery and wound care markets. We also are a leader in
cardiovascular medical technology, specifically, arterial revascularization and
puncture closure devices. We are in clinical trials with the Aegis Vortex
System, a device designed to remove occlusive material from saphenous vein
grafts implanted during coronary bypass surgeries. Additionally, we were the
original designers, developers and manufacturers of the Angio-Seal, a device
designed to seal and close femoral artery punctures made during diagnostic and
therapeutic cardiovascular catheterizations. We intend to leverage our
proprietary knowledge and expertise to develop new products and technologies and
to explore additional applications for our products.

BIOMATERIALS MARKET OPPORTUNITY

Biomaterials, which are substances that treat, augment, or replace tissue,
organs or body functions, are used regularly as components and elements in a
wide variety of resorbable and permanent implants. Advances in materials
technology and a better understanding of the biological processes involved in
tissue formation and remodeling have led to the introduction of resorbable
biomaterials based products to address long-standing deficiencies of traditional
products and therapies. This trend has been observed in many markets, including
orthopedics, cardiology, drug/biologics delivery, wound care, surgery, dentistry
and urology. Generally, resorbable biomaterials based products have proven
attractive solutions for a number of reasons. First, physicians like to use an
implant which will not require a second surgery to remove the device. In
addition, the rate of resorption of products can be carefully engineered to
promote healing as the biomaterials based products work with the body's natural
healing response. Finally, resorbable biomaterials offer tremendous potential
for drug delivery. The ability to provide staged and sustained release of drugs
and biologics is a critical attribute of the growth in the use of resorbable
biomaterials based products.

The technological challenges involved in developing biomaterials products
are substantial. Developing products made from resorbable biomaterials requires
an understanding of the mechanical integrity, biocompatibility, resorption rates
and ability to sterilize these products without jeopardizing the material
properties.

OUR BIOMATERIALS TECHNOLOGY

Our expertise in biomaterials enables us to design, develop and manufacture
proprietary biomaterials products. These products are characterized by their
ability to be resorbed or incorporated in the body's own tissue. Our particular
expertise is in the properties, usage and processing of collagen, polymers,
ceramics and other resorbable materials. We believe that our biomaterials
technology gives us a competitive advantage because we are able to provide the
essential biomaterials building blocks to address specific product needs.

- Polymers. We are a leader in the design, development and manufacture of
resorbable polymer products. We use many different types of polymers, in
combination or as single entities, to achieve the desired properties in a
particular product. We have developed several unique polymer based
materials, products and processes, which have a variety of applications
in implantable resorbable medical devices. We offer our customers and
partners a complete solution, including product design and engineering,
tool design, process development, commercial manufacture and packaging
configuration.

- Collagen and Other Naturally Occurring Materials. We design, develop and
manufacture products using naturally occurring materials such as
collagen, elastin, hyaluronic acid and alginate, which have applications
in a wide variety of resorbable medical devices. We are experts in
processing collagen into diverse product formulations, including powders,
gels, pastes, sponges and structural matrices. We combine collagen and
other naturally occurring materials using our proprietary processes,
thereby creating new materials with unique characteristics and diverse
product applications.

24
<PAGE> 27

We have completed extensive biocompatibility and viral inactivation studies on
our collagen products. We have established, and currently maintain, device
master files which contain the data from these studies. Our device master files
allow customers who incorporate our collagen products into their products
to reference our device master files in their regulatory submissions,
thereby eliminating the extensive and time consuming process of
independently generating their own data. We believe our ability to make
our device master files available to our customers provides us with a
significant competitive advantage.

- Ceramics Products. We are developing products using ceramic materials in
combination with other biomaterials that have applications in bone
grafting, spinal fusion, filling of bone defects and fracture repair. We
have ceramic experience primarily with calcium phosphate salts such as
hydroxyapatite. These materials can be designed to replicate bone
structure and support new bone growth or as osteoconductive implants.
Ceramics are also useful for enhancing the material properties of
products, such as strength, when used in combination with other
biomaterials.

OUR BIOMATERIALS STRATEGY

Our strategy is to expand our leadership position and expertise in
biomaterials products and technology. The components of our strategy are
presented below.

- Develop New Proprietary Biomaterials Products. We are leveraging our
technology and expertise to develop new proprietary biomaterials
products. We are experts in polymers, collagen and other resorbable
materials, as well as in processing these materials. In addition, we have
particular expertise in the use of biomaterials in the orthopedics,
cardiology, drug/biologics delivery and wound care markets. We are using
our expertise to develop new biomaterials products, new formulations of
existing biomaterials and new biomaterials applications. For example, we
are using our expertise in resorbable polymers and cardiovascular devices
to design and develop a resorbable polymer matrix to deliver angiogenic
growth factors to promote the growth of new blood vessels for use in
myocardial revascularization procedures.

- Expand Our Existing Biomaterials Business. We intend to aggressively
expand our existing biomaterials business by increasing sales to our
current customers and attracting new customers by providing proprietary,
technologically superior biomaterials products. We offer a complete range
of services including design, development, regulatory consulting,
manufacturing and package engineering. We will continue to invest in new
manufacturing technology and processes to meet our customers'
requirements, support product launches and increase the demand for our
biomaterials products. Additionally, we will expand our marketing efforts
to broaden our customer base in the orthopedic, cardiology,
drug/biologics delivery and wound care markets.

- Commercialize Biomaterials Products. We are increasing the level of value
we add to the services and products we sell to our customers and believe
we will be able to increase our financial participation in the
commercialization of these services and products. We either manufacture
our biomaterials products and provide them to our customers for
incorporation into their products or manufacture a complete product
incorporating our biomaterials and provide the finished product to our
customers for distribution. Currently, we are independently designing and
developing biomaterials products which may enhance the features and
benefits of our customers' products. In addition, we are independently
developing new proprietary products and exploring new commercial
relationships with customers to maximize our return on our increased
investment in these products. As we continue to increase our investment
in the development of new biomaterials and products, we believe we will
be able to retain an increased percentage of the financial return
associated with the commercialization of products using our biomaterials
technology.

- Pursue Strategic Acquisitions and Alliances. We will seek strategic
acquisitions and alliances which add complementary technologies and
expertise, broaden our intellectual property portfolio and strengthen our
competitive position in our biomaterials business. We believe that our
expertise in biomaterials allows us to identify and attract these
opportunities.

Orthopedic Products. Applications in the orthopedic market for our
biomaterials products include sports medicine, as well as spinal and trauma
fixation. Orthopedic applications of biomaterials include repair, regeneration
or augmentation of musculoskeletal tissues, including bone, cartilage,
ligaments, spinal discs and tendons. We estimate the potential market for
products we manufacture, develop and market in these segments to be in excess of
$600 million annually. Companies in this market often look to third parties to
develop and manufacture their product concepts into marketable products. Our
capabilities and expertise have enabled us to develop relationships with several
of the major orthopedic companies, which we provide with our biomaterials
products.

Many of our biomaterials products manufactured from resorbable materials
are designed to replace metallic devices used in the fixation and repair of
musculoskeletal tissues. Use of resorbable biomaterials eliminates the need for
a second surgery which is frequently necessary to remove non-resorbable metallic
implants like bone rods and pins. This benefit provides our customers with a
cost-effective alternative to traditional non-resorbable based products.

Sports Medicine. The primary application for biomaterials in the
sports medicine segment is soft tissue fixation. Soft tissue fixation
includes the repair of tendons and ligaments in the knee, such as the
meniscus and the anterior cruciate ligament, and in the shoulder, such as
the rotator cuff. The worldwide soft tissue fixation segment of the sports
medicine market was estimated to be approximately $360 million for 1999 and
is growing at an estimated 15% to 20% per year.

In soft tissue fixation, we have assisted in developing and
manufacturing three product lines marketed and sold by our customers.
Additionally, we have assisted in developing and will manufacture, six new
product lines for which our customers are awaiting regulatory approval.
These product lines include various types of resorbable screws, tacks and
other fixation devices.

Cranio-maxillofacial. Our biomaterial products address the repair of
the skull or bones of the face using resorbable tacks, screws and plates.
The potential worldwide market for our cranio-maxillofacial applications
was estimated to be $250 million for 1999. The cranio-maxillofacial market
is a subsegment of the trauma fixation market.

We have assisted with the design and the development of, and are
manufacturing, a product line for cranio-maxillofacial repair marketed and
sold by one of our customers. We also are assisting with the design and
development of a new product line for another customer. In addition, we are
developing proprietary technologies that will have applications in this
segment and intend to commercialize these technologies through arrangements
similar to our existing customer relationships.

Spinal Fixation. The primary application for our biomaterials in the
spinal fixation market is spinal fusion, a $405 million market in 1999.
Spinal fusion devices are used to restore normal spinal disc spacing and
fuse adjacent vertebrae for the correction of a spine or improvement in
chronic back pain. We supply our proprietary collagen products for use in
coating spinal fusion cages manufactured, marketed and sold by our
customer.

Trauma Fixation. Trauma fixation devices are used to repair broken
bones using nails, screws, plates, pins and bone growth stimulation
products. We are developing a product line with a customer incorporating
one of our proprietary biomaterials formulations. We also are working with
other customers to expand their product offerings by providing our
proprietary biomaterials products for incorporation into their products. We
are currently exploring the use of our biomaterials products to deliver
growth factors for applications in trauma fixation.

Cardiology Products. Our biomaterials are used in arterial puncture closure
products and coatings for synthetic vascular grafts. The potential worldwide
arterial puncture closure market is estimated to be between $750 million and $1
billion, with the U.S. market accounting for approximately 75%. We manufacture
the resorbable polymer anchor and collagen plug components for the Angio-Seal.
We also supply our proprietary collagen to a customer for use as a synthetic
vascular graft coating. We are independently developing a resorbable polymer
matrix to deliver angiogenic growth factors to promote the growth of new blood
vessels for use in myocardial revascularization procedures. We are also
independently exploring the use of our biomaterials in an arterial stent, a
stent cover, an anastomosis connector and a vascular graft.

Drug/Biologics Delivery Products. Biomaterials are particularly useful for
the controlled release of drugs and other biologically active agents such as
growth factors. In these applications, the drug is deposited or incorporated
into a biomaterials delivery matrix. As the matrix dissolves or is degraded by
the body, the drug is gradually released. The use of a biomaterials matrix for
drug delivery permits a

27
<PAGE> 30

locally targeted, low-dose release profile, improving the delivery of the drug.
We supply a proprietary collagen matrix to a customer which is developing a drug
delivery system to treat cervical cancer and dysplasia.

Wound Care Products. While the wound care market is currently dominated by
conventional bandages and dressings and surgical staples or sutures, there is a
new generation of products resulting from recent advances in biomaterials,
tissue engineering and biotechnology. We manufacture collagen which is
incorporated into an artificial skin product manufactured, marketed and sold by
our customer to treat burns and skin defects, a market of approximately $230
million in 1999. Additionally, we supply collagen for use in a topical wound
dressing manufactured, marketed and sold by our customer. We are independently
pursuing additional wound care applications for our biomaterials, including
surgical sealants and glues and adhesion prevention segments.

Surgery, Dentistry and Urology Products. Biomaterials are used in these
market segments in products ranging from resorbable sutures to tissue barriers
to stents. We intend to pursue the development of products for these markets.

THE AEGIS VORTEX SYSTEM

We are designing and developing the Aegis Vortex system to remove occlusive
material from saphenous vein grafts implanted during coronary artery bypass
surgeries. There are approximately 650,000 coronary bypass surgeries performed
annually worldwide and approximately half of all bypass grafts become diseased
or occluded within ten years of surgery. Saphenous vein grafts are used in
coronary bypass graft procedures as a replacement for the diseased or occluded
native artery to restore blood flow. The saphenous vein is removed from the
patient's leg and surgically implanted in place of the diseased or occluded
native artery. Current treatment options for diseased saphenous vein grafts
include drug therapy, device-based therapies (including angioplasty and the
placement of stents), repeat bypass surgery and transmyocardial
revascularization. There are significant risks involved with these treatments
ranging from continued progression of disease, heart attack and possible death.
We believe the use of the Aegis Vortex will reduce these risks for patients.

We believe the Aegis Vortex currently is the only device, in clinical
trials or commercially available, which offers all three of the following
features:

- a catheter with a high-speed rotating tip advanced over a guidewire that
delivers fluid to the vessel; the tip rotates at up to 150,000
revolutions per minute in order to dislodge and break the occlusion into
particles;

- a distal protection balloon placed beyond the occlusion to prevent debris
from flowing downstream and potentially causing a heart attack; and

- a controlled extraction system which removes the debris.

[ART]
The picture located at the bottom of this page depicts the Aegis Vortex being
employed on a blocked diseased graft.

28
<PAGE> 31

To operate the Aegis Vortex system, a guiding catheter is positioned at the
entrance to the graft. The guidewire, containing the distal protection balloon,
is advanced through the saphenous vein graft beyond the occlusion. The distal
protection balloon is inflated and the rotating tip catheter is advanced over
the guidewire and through the diseased or occluded graft. Saline and contrast
media are delivered into the graft from the catheter. The combination of the
rotating catheter tip and saline and contrast media create a vortex which
dislodges and breaks up the occlusive material. The particles and debris that
are dislodged by the rotating tip catheter are extracted through the lumen of
the guiding catheter.

We have completed an initial 17 patient pilot clinical trial of the Aegis
Vortex. We believe this trial demonstrated the safety and feasibility of the
Aegis Vortex in humans. We are incorporating design enhancements and planning
our pivotal trial protocol. We expect to submit an investigational device
exemption, or IDE, supplement to the FDA during the second quarter of fiscal
year 2001 to initiate additional trials of the device. We anticipate beginning a
trial in Europe during the fourth quarter of fiscal year 2000 which will be used
as support for a CE Mark filing. The CE Mark is an international symbol of
adherence to quality assurance standards established by the European Union and
compliance with applicable European medical device directives.

We intend to commercialize the Aegis Vortex by building a direct sales and
marketing force in the interventional cardiology market or establishing a
strategic alliance with a leader in this market.

We intend to modify the design of the Aegis Vortex to address additional
related applications including the treatment of diseased native coronary and
peripheral arteries and the re-occlusion of stented arteries. We are currently
evaluating selected design modifications to address these applications.

THE ANGIO-SEAL

The Angio-Seal is a leader in the worldwide arterial puncture closure
market with over 770,000 devices sold to date. We estimate the Angio-Seal
worldwide market share in 1999 was approximately 35%. We believe there are
approximately 6.5 million cardiovascular catheterization procedures performed
annually. The potential worldwide arterial puncture closure market is estimated
to be between $750 million and $1 billion, with the U.S. market accounting for
approximately 75%. We believe that current U.S. market penetration of arterial
puncture closure devices is approximately 20% and the international market
penetration is approximately 5%.

The Angio-Seal is a puncture closure device that acts to close and seal
femoral artery punctures made during diagnostic and therapeutic cardiovascular
catheterizations. The device consists of four components:

- a resorbable polymer anchor seated securely against the inside surface of
a patient's artery at the point of puncture;

- a resorbable collagen plug applied adjacent to the outside of the artery
wall;

- a resorbable suture; and

- a delivery system consisting 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 and close the
puncture. A tamper tube is used to further position and secure the closure
device. The anchor, collagen and suture are all designed to be resorbed into the
patient's body within 60 to 90 days after the procedure. We believe that this
mechanical (via the anchor and collagen) and biochemical (via the collagen) seal
offers physicians a method for sealing and closing punctures with significant
advantages over traditional manual or mechanical compression methods, as well as
over other competitive products. We believe the Angio-Seal has several
advantages over traditional manual or mechanical compression procedures,
including: reduced time to ambulation, reduced staffing and hospital time,
possible reduction in procedure costs, increased patient comfort, greater
flexibility in post-procedure blood thinning therapy and increased blood flow to
the leg.

The Angio-Seal is manufactured, marketed, sold and distributed by St. Jude
Medical. We receive a royalty on every Angio-Seal unit sold. In addition, we
have manufactured components for all Angio-Seal devices and augmented St. Jude
Medical's manufacturing of completed devices. In December 1999, St. Jude Medical
significantly expanded its U.S. sales and marketing efforts for the Angio-Seal.
In early 2000, the 6F Angio-Seal was approved for sale in the U.S. The 6F
device, the smallest and latest size of the Angio-Seal device, specifically
addresses arterial punctures created during diagnostic angiograms, which account
for approximately 70% of all cardiac catheterization procedures. In the
international market, the 6F device was approved in early 1999 and its sales
have increased significantly since the launch. We believe the impact of the
additional sales and marketing efforts, along with the 6F device U.S. launch and
new product enhancements planned by St. Jude Medical, will provide additional
growth opportunities for the Angio-Seal.

PATENTS AND PROPRIETARY RIGHTS

Our intellectual property covers technology in the fields of arterial
puncture closure, blood vessel location, arterial revascularization systems,
drug/biologics delivery products, wound care products, angiogenesis products and
surgical instruments. We protect our technology by, among other things, filing
patent applications for the patentable technologies that we consider material to
our business. Our first U.S. patent for the concept of sealing arterial
punctures was issued in 1988. As of May 1, 2000, we held 59 United States
patents and 71 foreign national patents and had several United States patents
and foreign national patent applications pending.

We also rely heavily on trade secrets and unpatented proprietary know-how
which we seek to protect through non-disclosure agreements with corporations,
institutions and individuals exposed to our proprietary information. As a
condition of employment, we require that all full-time and part-time employees
enter into an invention assignment and non-disclosure agreement.

We have licensed our United States and foreign patents for the Angio-Seal
to St. Jude Medical and are required to license all improvements for Angio-Seal
to St. Jude Medical. The license agreements with St. Jude Medical are exclusive
and 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.

We will continue to aggressively protect any new manufacturing processes,
biomaterials products and technologies and medical products and devices. We
intend to broaden the scope of our intellectual property and consider our core
technologies to be critical to our future product development.

MANUFACTURING

We have developed unique manufacturing and processing capabilities for
resorbable collagen and polymers. We manufacture numerous resorbable
biomaterials products for use in applications including orthopedics, cardiology,
drug/biologics delivery and wound care. We have our own capabilities in tool and
die making, injection molding, extrusion, compounding, machining, model making
and laser welding, which allows us to engineer and reengineer our products in
development on site.

To date, our Angio-Seal manufacturing activities have consisted primarily
of producing Angio-Seal devices for use worldwide in clinical trials and
partially and fully completed commercial devices for sale in the U.S. and
Europe. Historically, we have manufactured two of the major resorbable
components of the Angio-Seal, the collagen plug and polymer anchor, to fulfill
the worldwide requirements of St. Jude Medical and our previous partners for
Angio-Seal. St. Jude Medical has the right to manufacture the resorbable polymer
anchor and intends to manufacture that component in the future. However, we
anticipate we will continue to be an additional source of anchor requirements
through the end of fiscal year 2000.

Our FDA-registered manufacturing facility in Exton, Pennsylvania contains
separate areas for Angio-Seal assembly, resorbable collagen and polymer
manufacturing. Our manufacturing 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.
Our manufacturing facility is subject to regulatory requirements and periodic
inspection by regulatory authorities. We have a separate in-house quality
assurance department that sets standards, monitors production, writes and
reviews operating procedures and protocols and performs final testing of sample
devices and products manufactured by or for us.

We purchase most raw materials, parts and peripheral components used in our
products. Although many of these supplies are off-the-shelf items readily
available from several supply sources, others are custom-made to meet our
specifications. We believe 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.

RESEARCH AND DEVELOPMENT

Our research and development and regulatory and clinical staff consisted of
39 individuals at May 1, 2000. Our research and development efforts are focused
on the development of the Aegis Vortex and the continued development of our
biomaterials capabilities. We incurred total research and development expenses
of $4.7, $5.5 and $5.7 million in the fiscal years ended June 30, 1997, 1998 and
1999, respectively.

In addition to the resources dedicated to the product development process,
we have an internal regulatory affairs and clinical management staff responsible
for managing our clinical trials for the Aegis Vortex. Our staff worked closely
with our strategic partners to gain regulatory approvals for additions to the
Angio-Seal product lines in the U.S., the European Union and several other
countries.

OUR RELATIONSHIP WITH ST. JUDE MEDICAL

We have a strategic alliance with St. Jude Medical who manufactures,
markets and sells the Angio-Seal worldwide. The Angio-Seal has been sold in
Europe since 1995 and in the U.S. since 1996. The Angio-Seal is now sold in the
U.S., Europe, Canada, Latin America and Australia, among other countries. To
date, there have been over 770,000 devices sold to end users.

Under our license agreements, St. Jude Medical has exclusive rights to
manufacture, market and distribute all current and future sizes of the
Angio-Seal for cardiovascular use worldwide. We retain the rights to use our
puncture closure technology for other applications. We earn a royalty on each
Angio-Seal sold by St. Jude Medical. The royalty rates are based on aggregate
volume of Angio-Seals sold. We expect a reduction in our royalty rate during the
second quarter of fiscal year 2001. These royalty agreements provide for minimum
royalty payments for five years following FDA approval (ending September 30,
2001). If St. Jude Medical fails to pay the minimum royalty, the license
agreements become non-exclusive. This right of conversion is our sole remedy for
St. Jude Medical's failure to make any minimum royalty payment, and if it is
exercised, St. Jude Medical has no further obligation to make any minimum
royalty payments.

The term of the license agreements extends to the expiration date of the
most recently issued licensed patent, including all continuations or
supplements. The most recent patent for the Angio-Seal technology was issued in
1999, although we have applied for, and expect to have issued to us, additional
patents. St. Jude Medical may terminate the license agreements any time after
the fifth royalty year (ending September 30, 2001) 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
us, on a territory-by-territory basis, in an amount not to exceed in any one
year one-half of any royalties in any such territory for that year. "Angio-Seal"
is a trademark of St. Jude Medical.

SALES AND MARKETING

As we develop and receive regulatory approval for new products, we will
explore a variety of means of commercializing these products. As a result, we
may contract with distributors, develop our own sales and marketing force and/or
license products to third parties. We have no experience hiring or training a
sales and marketing force and we may not be able to maintain a sales and
marketing force with technical expertise and the necessary supporting
distribution capabilities. We recently created a new senior marketing position
and hired someone to fill this position. This person is responsible for leading
our expanded marketing and sales efforts and further developing our future
distribution strategy for the Aegis Vortex.

32
<PAGE> 35

COMPETITION

The market for our various products is fragmented, competitive and rapidly
changing. We compete directly and indirectly for customers with a wide variety
of companies. We believe that the principal competitive factors for our products
include:

- the ability to obtain regulatory approvals;

- safety and effectiveness;

- performance and quality;

- marketing;

- distribution;

- pricing;

- cost effectiveness;

- customer service;

- the development or acquisition of proprietary products and processes;

- the ability to attract and retain skilled personnel;

- improvements to existing technologies;

- reimbursement; and

- compliance with regulations.

We believe our products compete favorably with those of our competitors.
However, many of our existing competitors, as well as a number of potential new
competitors, have longer operating histories in these markets, greater name
recognition, larger customer bases and greater financial, technical and
marketing resources.

GOVERNMENT REGULATION

Our medical devices are subject to extensive regulation by the Food and
Drug Administration, or FDA, and by foreign governments. The FDA regulates the
clinical testing, design, 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
recall, request repair, replacement or refund of the cost of any device we
manufacture or distribute.

FDA premarket approval was granted for the Angio-Seal 8F device in
September 1996 and for the 6F device in early 2000. St. Jude Medical is
responsible for all future FDA premarket approval application supplements for
the Angio-Seal device. The 8F Angio-Seal received CE Mark approval from the
European Community in September 1995. The 6F Angio-Seal received CE Mark
approval in February 1999.

The Angio-Seal is also available for sale in a number of other countries.
International sales of medical devices are subject to the regulatory agency
product registration requirements of each country in which they are sold. The
regulatory review process varies from country to country. Many countries also
impose product standards, packaging requirements, labeling requirements, price
restraints 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 our
business, financial condition and results of operations. In addition,
reimbursement coverage must be obtained in some countries.

33
<PAGE> 36

Generally, our biomaterials products are incorporated by our customers into
another product which receives FDA approval. We maintain device master files for
some of our biomaterials products containing information relating to the
specifications, manufacturing, biochemical characterization, biocompatibility
and viral safety of our biomaterials products. These files, in addition to our
technical expertise, help our clients in their regulatory approval process for
products incorporating our biomaterials.

We must obtain CE Mark approval and premarket approval from the FDA, as
well as all future premarket approval application supplements for the Aegis
Vortex. We expect to submit an IDE supplement to the FDA during the second
quarter of fiscal year 2001 to initiate additional trials of the device.

When human clinical trials of a device are required in connection with our
new proprietary products and the device presents a significant risk, we must
file an IDE application with the FDA prior to commencing human clinical trials.
The IDE application must be supported by data, typically including the results
of animal and laboratory testing. If the IDE application is approved, human
clinical trials may begin at a specific number of investigational sites with a
specific number of patients, as approved by the FDA. The conduct of human
clinical trials is also subject to regulation by the FDA. Sponsors of clinical
trials are permitted to sell those devices distributed during the course of the
trial provided such compensation does not exceed recovery of the costs of
manufacture, research, development and handling. Similar approvals are required
to conduct clinical trials in foreign countries.

Any products we manufacture or distribute 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. As a device manufacturer, we are required to register our
manufacturing facility with the FDA; list our devices with the FDA; and are
subject to periodic inspections by the FDA and certain state agencies. The
Federal Food, Drug, and Cosmetic Act requires devices to be manufactured in
accordance with Quality System regulations which impose certain procedural and
documentation requirements 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.

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. We may be required to incur significant costs
to comply with such laws and regulations in the future and any failure to comply
with such laws or regulations will have a material adverse effect upon our
ability to do business.

EMPLOYEES

As of May 1, 2000, we have 140 employees, including 66 full time and 20
temporary employees in operations, 39 employees in research and development and
clinical and regulatory affairs and 15 employees in finance and administration.
All of our employees are located at our facility in Exton, Pennsylvania. We
believe that our success depends in a large part on our ability to attract and
retain employees in all areas of our business.

PROPERTIES

We lease approximately 44,000 square feet of executive offices,
manufacturing and research and development facilities in Exton, Pennsylvania, a
suburb of Philadelphia. Our lease expires in 2005, subject to renewal options.
We believe that our facility is sufficient for our current operations.

LEGAL PROCEEDINGS

In March 1998, we, along with our former Angio-Seal strategic partner,
filed a patent infringement suit against Perclose, Inc., a competitor in the
puncture closure market. Upon their acquisition of the

34
<PAGE> 37

Angio-Seal license in March 1999, St. Jude Medical, as part of the transaction,
assumed certain rights and responsibilities with respect to the lawsuit from our
previous partner. In 1999, we amended the complaint to add a second patent to
the infringement suit. The original and amended complaints, filed in the Eastern
District of Pennsylvania, claim that Perclose infringes our U.S. patent numbers
5,676,689 and 5,861,004. These patents cover systems and methods related to
sealing percutaneous punctures. We seek damages and an order to permanently
enjoin Perclose from making, using or selling products that infringe these
patents.

Perclose filed four counterclaims against us and our strategic partner's
predecessor in answer to the complaint. The first counterclaim seeks to declare
our patents invalid and not infringed. The additional counterclaims asserted by
Perclose allege that our claims are frivolous and assert various antitrust
counter-claims, including price discrimination, predatory pricing and attempted
monopolization of the puncture closure market. We are unable to predict the
final outcome of this suit or whether the resolution of this matter could
materially affect our results of operations, cash flows or financial position.
Abbott Laboratories acquired Perclose in November 1999.

CERTAIN TRANSACTIONS

We have pledged $1.9 million in investments as collateral to secure bank
loans made to employees to pay taxes incurred by these employees when they
received common stock at the time of our initial public offering. In exchange
for our pledging collateral for these loans, each employee has pledged his
common stock to us as collateral. The aggregate balance outstanding on these
employee loans was $2.0 million at March 31, 2000.

We have entered into a loan agreement with Joseph W. Kaufmann under which
he has borrowed $700,000 from us since November 1998 at an interest rate of 7%
per annum. This interest rate was the most favorable investment rate available
to us at the time the loan was made, plus 1%. In exchange for the loan, Mr.
Kaufmann has pledged his common stock as collateral to us. The term of the loan
expires on January 2, 2001 unless Mr. Kaufmann's employment with us is
terminated or he sells all of his common stock before January 2, 2001, in which
case the loan will immediately become due and payable.

The loans from the bank and us will be repaid if the underwriters exercise
their over-allotment option to purchase shares of our common stock from the
other selling stockholders.

SHARES ELIGIBLE FOR FUTURE SALE

The market price of our common stock could decline due to sales of a large
number of shares of our common stock or the perception that these sales could
occur. These factors could also make it more difficult to raise funds through
future offerings of common stock.

After this offering, 9,992,488 shares of common stock will be outstanding,
10,272,488 shares if the underwriters exercise their over-allotment options from
us in full. All of the shares sold in this offering will be freely tradeable
without restriction under the Securities Act except for any shares purchased by
our affiliates as defined in Rule 144 under the Securities Act.

We and our officers and directors, including the other selling
stockholders, have entered into lock-up agreements pursuant to which we and they
have agreed not to offer or sell any shares of common stock or securities
convertible into or exchangeable or exercisable for shares of common stock for a
period of 90 days from the date of this prospectus without the prior written
consent of Prudential Securities Incorporated, on behalf of the underwriters.
Kenneth R. Kensey, M.D. and John E. Nash, P.E. have entered into similar
agreements for a period of 180 days and one year, respectively. Virtually all of
Dr. Kensey's shares are subject to pledge agreements with third parties. These
pledge agreements provide that if the price of our common stock falls below
certain levels, the pledged shares could be sold by third parties into the
public market. Prudential Securities Incorporated may, at any time and without
notice, waive any of the terms of these lock-up agreements specified in the
underwriting agreement. Following the lock-up period, these shares will not be
eligible for sale in the public market without registration under the Securities
Act unless these sales meet the conditions and restrictions of Rule 144 as
described below.

shares for a period of at least one year is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of

- 1% of the then outstanding shares of common stock and

calendar weeks immediately preceding the date on which the notice of such

In addition, a person (or persons whose shares are aggregated) who has not
been an affiliate of ours at any time during the 90 days immediately preceding a

with Prudential Securities Incorporated, PaineWebber Incorporated and Warburg
Dillon Read LLC. We and the selling stockholders are obligated to sell, and the
underwriters are obligated to purchase, all of the shares offered on the cover
page of this prospectus, if any are purchased. Subject to certain conditions in
the underwriting agreement, each underwriter has severally agreed to purchase
the shares indicated opposite its name:

The underwriters may sell more shares than the total number of shares
offered on the cover page of this prospectus and they have, for a period of 30
days from the date of this prospectus, over-allotment options to purchase up to
280,000 additional shares from us and up to 200,000 additional shares from two
other selling stockholders. If any additional shares are purchased, the
underwriters will severally purchase the shares in the same proportion as per
the table above.

The underwriters have advised us and the selling stockholders that the
shares will be offered to the public at the offering price indicated on the
cover page of this prospectus. The underwriters may allow to selected dealers a
concession not in excess of $ per share and these dealers may allow a
concession not in excess of $ per share to some other dealers. After
the shares are released for sale to the public, the underwriters may change the
offering price and the concessions.

We and the selling stockholders have agreed to pay to the underwriters the
following fees, assuming both no exercise and full exercise of the underwriters'
over-allotment options to purchase additional shares:

In addition, we estimate that we will spend approximately $ in

Prudential Securities Incorporated, on behalf of the underwriters, may
engage in the following activities in accordance with applicable securities
rules:

- Over-allotments involving sales in excess of the offering size, creating
a short position. Prudential Securities Incorporated may elect to reduce
this short position by exercising some or all of the over-allotment
options.

- Stabilizing and short covering: stabilizing bids to purchase the shares
are permitted if they do not exceed a specified maximum price. After the
distribution of shares has been completed, short covering purchases in
the open market may also reduce the short position. These activities may
cause the price of the shares to be higher than would otherwise exist in
the open market.

- Penalty bids permitting the representatives to reclaim concessions from a
syndicate member for the shares purchased in the stabilizing or short
covering transactions.

These activities, which may be commenced and discontinued at any time, may
be effected on the Nasdaq National Market, in the over-the-counter market or
otherwise. Also and prior to the pricing of the shares, and until some time when
a stabilizing bid may have been made, some or all of the underwriters who are
market makers in the shares that make bids for or purchases of shares subject to
certain restrictions, known as passive market making activities.

Each underwriter has represented that it has complied and will comply with
all applicable laws and regulations in connection with the offer, sale or
delivery of the shares and related offering materials in the United Kingdom,
including:

- the Public Offers of Securities Regulations 1995,

- the Financial Services Act 1986, and

- the Financial Services Act 1986 (Investment Advertisements) (Exemptions)
Order 1996 (as amended).

Prudential Securities Incorporated facilitates the marketing of new issues
online through its PrudentialSecurities.com division. Clients of Prudential

KENSEY NASH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

NOTE 1 -- CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

The consolidated balance sheet at March 31, 2000, the consolidated
statements of operations for the three and nine months ended March 31, 2000 and
1999 and the consolidated statements of cash flows for the nine months ended
March 31, 2000 and 1999 have been prepared by Kensey Nash Corporation (the
"Company") and have not been audited by the Company's Independent Auditors. In
the opinion of management, all adjustments (which include only normal recurring
adjustments) necessary to present fairly the financial position, results of
operations and cash flows at March 31, 2000 and for all periods presented have
been made.

Certain information and note disclosures normally included in the Company's
annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. These consolidated
financial statements should be read in conjunction with the financial statements
and notes thereto included in the Company's June 30, 1999 consolidated financial
statements filed with the Securities and Exchange Commission on Form 10-K. The
results of operations for the period ended March 31, 2000 are not necessarily
indicative of operating results for the full year.

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.

EXPORT SALES

There were no export sales from the Company's US operations to unaffiliated
customers in Europe for the three months ended March 31, 2000. Export sales
totaled $102,878 for the three months ended March 31, 1999 and $206,045 and
$242,893 for the nine months ended March 31, 2000 and 1999, respectively.

EARNINGS PER SHARE

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.

COMPREHENSIVE INCOME

Accumulated other comprehensive loss, shown in the consolidated statements
of shareholders' equity at March 31, 2000 and June 30, 1999, 1998 and 1997, is
solely comprised of unrealized losses on the Company's available-for-sale
securities. There were no unrealized gains or losses in the year ended June 30,
1998. The tax effect of other comprehensive income on fiscal years 2000 and 1999
was not significant.

NOTE 2 -- DEFERRED REVENUE -- ROYALTIES

Upon receipt of pre-market approval for the 8 French ("F") size Angio-Seal
device (the "Angio-Seal") from the Food and Drug Administration (the "FDA") on
September 30, 1996, the Company received a $3 million advance on future
royalties under the Company's licensing agreement (the "Licensing Agreement")
with its strategic partner, St. Jude Medical, Inc. ("St. Jude Medical"). Such
advance was recorded as deferred revenue. The Licensing Agreement provides for
certain minimum royalty payments ("Minimum Royalty") during the first five years
after receiving FDA approval (each royalty year begins on October 1 and ends on
September 30). As stipulated in the Licensing Agreement, the $3.0 million
advance was reduced in

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

each period by 50% of royalties earned in excess of the Minimum Royalty in any
royalty year. The remainder of royalties earned was received as cash proceeds by
the Company. At March 31, 2000 the entire $3.0 million royalty advance had been
repaid by the Company through these royalty payment reductions.

NOTE 3 -- 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:

</TABLE>

NOTE 4 -- COMMITMENTS AND CONTINGENCIES

The Company has pledged $1,949,386 in investments as collateral to secure
certain bank loans to employees which were used by such employees for the
payment of taxes incurred by such employees as the result of the receipt of
Common Stock in settlement of the employee stock rights. 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 $1,975,908 at March 31, 2000.

In addition, under the terms of the Company's Financing Agreement, the
Company has placed the remaining proceeds of such agreement into a certificate
of deposit ("CD"). The CD is restricted for capital expenditure purposes only.
The balance of the CD at March 31, 2000 was $506,339 and is included in
restricted investments due to the capital expenditure restriction placed on its
use.

NOTE 5 -- INCOME TAXES

As of June 30, 1999, the Company had net operating loss carryforwards for
federal and state tax purposes totaling $14.8 and $3.0 million, respectively. As
such, no provision has been made for income taxes for the three or nine months
ended March 31, 2000 or 1999. A portion of the NOL may be subject to various
statutory limitations as to its usage.

NOTE 6 -- 6F ANGIO-SEAL FDA APPROVAL

In March 2000, the Company announced that the FDA granted approval to St.
Jude Medical, Inc. for the new 6F Angio-Seal puncture closure device, allowing
sale of the product in the United States. This smaller version of the Angio-Seal
is designed to seal arterial punctures 6F and smaller and specifically address
the largest segment of the puncture closure market.

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, 1999 and 1998, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended June 30, 1999. 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, 1999 and 1998, and the results of its operations and its cash flows for
each of the three years in the period ended June 30, 1999 in conformity with
generally accepted accounting principles.

KENSEY NASH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

YEARS ENDED JUNE 30, 1999, 1998 AND 1997

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 is a leader in the cardiac catheterization puncture closure market with
its Angio-Seal device. 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's
next product in the cardiovascular market is a revascularization device, the
Aegis Vortex System ("AVS"), which is currently in clinical trials. The AVS is a
device designed to open blocked saphenous vein grafts while minimizing the risk
of embolization, a common problem with current treatment alternatives. The
Company also has leading technology in the area of absorbable biomaterials,
including applications in orthopedics, cardiovascular, tissue regeneration, drug
delivery and many others. 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, 1999 and 1998. The fair value of short-term investments is based on
quoted market prices.

INVESTMENTS -- Investments at June 30, 1999 consist of short-term
Certificates of Deposit and Government Bonds. 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 or restricted as to use 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 (see
"Comprehensive Income"). Realized gains and losses are included in interest
income.

COMPREHENSIVE INCOME -- Effective July 1, 1998 the Company adopted SFAS No.
130, Reporting Comprehensive Income ("SFAS 130"), which establishes new rules
for the reporting and display of comprehensive income and its components.
Accumulated other comprehensive loss, shown in the consolidated statements of
shareholders' equity at June 30, 1999, 1998 and 1997, is solely comprised of
unrealized losses on the Company's available-for-sale securities. There were no
unrealized gains or losses in the years ended June 30, 1998 and 1997. The tax
effect for 1999 other comprehensive income was not significant.

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:

</TABLE>

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.

ACCOUNTS RECEIVABLE ALLOWANCE -- The Company has a trade receivable
allowance of $19,000 at June 30, 1999. During the year, the Company established
trade receivable allowances of $59,376 and wrote off amounts totaling $40,376.
This amount is included in selling, general and administrative expense for the
year ended June 30, 1999.

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 14 to 15 years at June 30, 1999.

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 sales revenue is recognized when the
related product is shipped.

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

EARNINGS PER SHARE -- 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 (see Note 15).

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 stock. The Company's policy is to grant
stock options at the fair market value at the date of grant (see Note 14).

NEW ACCOUNTING PRONOUNCEMENTS -- In June 1998, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The Company is not
required to adopt this standard until fiscal 2001 (as deferred by SFAS No. 137,
Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective Date of FASB Statement No. 133). At this time, the Company has not
determined the impact this standard will have on the Company's financial
statements.

PRESENTATION -- Certain items in the 1998 and 1997 consolidated financial
statements have been reclassified to conform with the presentation in the 1999
consolidated financial statements.

2. STRATEGIC ALLIANCE AGREEMENTS

The Company has a strategic alliance with St. Jude Medical, Inc. ("St.
Jude") which incorporates United States and foreign license agreements
(together, the "License Agreements"), a research and development agreement and a
collagen supply agreement (collectively, the "Strategic Alliance Agreements").
The Strategic Alliance Agreements were formerly with The Kendall Company
("Kendall"), a subsidiary of Tyco International, Ltd. ("Tyco"). In November
1998, Kendall announced the sale of the Angio-Seal License Agreements to St.
Jude. Under the terms of the sale, the Company's Strategic Alliance Agreements
with Kendall were transferred to St. Jude. Prior to Kendall, the Strategic
Alliance Agreements had been with American Home Products. The Company's current
or previous alliance partners will be referred to as the Strategic Alliance
Partner throughout.

THE LICENSE AGREEMENTS -- Under the License Agreements, St. Jude has
exclusive rights to manufacture and market all current and future sizes of the
Angio-Seal worldwide. Also 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
US 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 receipt of 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,
1999, the Company had exceeded the first, second and third royalty year (periods
ended September 30, 1997, 1998 and 1999) Minimum Royalties by $352,310,
$3,058,970 and $1,812,529, respectively. The deferred revenue balance has been
reduced by 50% of such total excess, to $388,096. The Company anticipates the
remainder of the deferred royalty balance will be repaid during the fiscal year
ended June 30, 2000. As such, the entire balance has been classified as
short-term at June 30, 1999.

During 1999, the Company received additional royalty payments (the
"Supplemental Royalty") from the previous owner of the Angio-Seal License
Agreements, TYCO, in the amount of $1.5 million. The Supplemental Royalty was to
compensate the Company for lost Angio-Seal sales and expenses incurred during
the ongoing transition of corporate ownership of the Angio-Seal License
Agreements to St. Jude. The payments were made in two equal installments on
March 29, 1999 and April 5, 1999. As such, the Company has recorded the $1.5
million as royalty income for the year ending June 30, 1999.

THE RESEARCH AND DEVELOPMENT AGREEMENT -- The Company and its Strategic
Alliance Partner had an agreement whereby such partner funded certain ongoing
research and development costs incurred by the Company. The Company contributed
one-third of such research and development costs while the Strategic Alliance
Partner contributed the remaining two-thirds. This agreement has expired and the
Company's Strategic Alliance Partner will be performing any remaining
development work on the Angio-Seal product line.

F-15
<PAGE> 62

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, the price of which fluctuates based on size and cumulative quantities
sold, for five years beginning May 31, 1995.

3. LEASES

At June 30, 1999, future minimum annual rental commitments under
non-cancelable lease obligations are as follows:

<TABLE>

Rent expense for operating leases consists solely of rent for the Company's
facility in Exton, Pennsylvania. Rent expense for the fiscal years ended June
30, 1999, 1998 and 1997 was approximately $360,341, $326,000 and $275,000,
respectively.

Capital leases are for various types of equipment, as follows:

========= =========
</TABLE>

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.

4. OFFICER LOANS

The Company has loans to a current officer of the Company totaling $250,000
which are collateralized by the officer's stock. Interest on the loans ranges
from 7% to 8.75% and was based on the prime rate of interest at the time the
advances were made. Total interest income earned by the Company on these loans
was $9,174, $4,750 and $611 for the years ended June 30, 1999, 1998 and 1997,
respectively. Interest and principal on the loans are due at the sooner of the
sale of a portion of the officers' common stock or June 22, 2000.

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, beginning

F-16
<PAGE> 63

January 1, 1998, the Company earns 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, them present value of the
cash payments (discounted based upon the Company's available borrowing rate at
the time of the transaction of 8.5%) was recorded as a liability on the
Company's financial statements, with a remaining balance of $503,453 at June 30,
1999 (see Note 6). The remaining unamortized discount under the agreement based
on imputed interest was $21,547 and $70,771 at June 30, 1999 and 1998,
respectively. The remaining quarterly payments are due by December 31, 1999 and,
as such, have been classified as short term at June 30, 1999. 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

TERM LOAN -- The Company had a $2 million revolving credit and term loan
agreement (the "Term Loan"). The Term Loan bore interest at the prime rate (8.5%
at June 30, 1998) and called for interest only payments until August 1, 1998
(the "Term Date") at which time it converted to a term loan due in 60 monthly
installments of principal and interest. At June 30, 1998, the Company had
borrowed $2.0 million under the Term Loan. In January 1999, the Company
refinanced $925,000 of the outstanding balance under the Term Loan with a $5.0
million financing agreement with a bank (the "Financing Agreement"). The
interest rate on the remaining $1,075,000 under the Term Loan was modified to a
fixed 8.0% and the Term Date was extended to February 1, 2000. Accordingly,
$74,447 has been classified as short term at June 30, 1999.

FINANCING AGREEMENT -- In January 1999, the Company entered into a $5
million financing agreement with a bank (the "Financing Agreement"). Under the
terms of the Financing Agreement, the bank purchased the Company's $5 million
tax-exempt bond issue (the "Bond Issue"), which was provided through the local
development authority. The Financing Agreement bears interest at the five year
Treasury rate plus 1%, adjusted quarterly (6.25% at June 30, 1999) and calls for
twenty-four interest only payments followed by sixty monthly installments of
principal and interest. The Financing Agreement is collateralized by the assets
of the Company.

The Company used $925,000 of the proceeds of the Bond Issue to pay down the
balance under its existing Term Loan. The remaining proceeds of the Bond Issue
were placed into a certificate of deposit (the "CD") from which withdrawals are
restricted for capital expenditure purposes only. The balance of the CD at June
30, 1999 is $2,726,339 and is included in restricted investments due to the
capital expenditure restriction placed on its use.

Amounts outstanding under the Company's Term Loan, Financing Agreement and
Patent Acquisition Agreement (see Note 5) are shown in the following table.

The annual debt maturities are approximately $577,900, $548,848,
$1,107,293, $1,182,342 and $1,262,534 for the years 2000 through 2004,
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 1999 the Company has not provided for current income taxes due to the
utilization of NOLs for tax purposes. The differences between the Company's
income tax expense (benefit) and the income tax expense (benefit) computed using
the US 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, 1999, the
Company had NOL carryforwards for federal and state tax purposes totaling $14.8
and $3 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 $1,949,386 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 at the
Company's Initial Public Offering in December 1995. 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 $1,879,286 at June 30, 1999.

10. 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 $1,309,882 as final settlement for business
interruption as a result of this event in December 1996. Of this amount $968,761
(net of adjuster fees) was recorded as a component of other income for the year
ended June 30, 1997.

11. 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 (67% and 100% of trade and royalty receivables, respectively,
at June 30, 1999) (see Note 2). The

F-19
<PAGE> 66

Company performs ongoing credit evaluations on the remainder of its customers'
financial conditions but does not require collateral to support customer
receivables.

12. CERTAIN COMPENSATION AND EMPLOYMENT AGREEMENTS

The Company has entered into employment agreements with certain of its
officers which provide for aggregate annual base salaries of $748,662 through
June 2000.

13. 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, 1999 and 1998 no shares of Preferred
Stock were outstanding. The Company has no present intention to issue shares of
Preferred Stock.

14. 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 2.2 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, 1999, awards consist solely of stock options as summarized in the
table below.

During 1995, the Company adopted the Non-employee 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.

Each non-employee director was granted an option to purchase 5,000 shares
of Common Stock on the Directors' Plan's effective date. In addition, the
Director's plan provides for the 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. The participant must either
be continuing as a non-employee director subsequent to the meeting or have been
elected at such meeting to serve as a non-employee 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.

The Company has adopted the disclosure only provisions of SFAS No. 123,
Accounting for Stock Based Compensation. Accordingly, no compensation cost has
been recognized for the Company's two stock option plans. Had compensation cost
for the plans been determined based on the fair market value at the grant date
for awards, consistent with the provisions of SFAS No. 123, the Company's net
loss and earnings per share would have been reduced to the proforma amounts

16. SEGMENT REPORTING

Effective July 1, 1998, the Company adopted SFAS No. 131, Disclosures about
Segments of an Enterprise and Related Information. SFAS No. 131 requires the
Company to use the "management approach" for identifying operating segments and
establishes annual and interim reporting standards for these operating segments.
The statement also establishes standards for related disclosures about products
and services and geographic areas. The Company's operations and products have
been aggregated into a single reportable segment, as permitted under SFAS No.
131, since they have similar economic characteristics, production processes,
types of customers and distribution methods.

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. In 1999,
the Company amended the claim to add a second patent to the infringement suit.
The original and amended suits, filed in the Eastern District of Pennsylvania,
claim that Perclose infringes the Company's US Patent Nos. 5,676,689 and
5,861,004 (together, the "Patents"). The Patents cover 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 Patents.

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. The Company
has expensed legal costs, as a component of selling, general and administrative
expenses, as services have been incurred.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The registrant's Second Amended and Restated Certificate of Incorporation
provides that the registrant shall indemnify its directors to the full extent
permitted by the General Corporation Law of the State of Delaware and may
indemnify its officers and employees to such extent, except that the registrant
shall not be obligated to indemnify any such person (1) with respect to
proceedings, claims or actions initiated or brought voluntarily by any such
person and not by way of defense, or (2) for any amounts paid in settlement of
an action indemnified against by the registrant without the prior written
consent of the registrant. In addition, the registrant's Second Amended and
Restated Certificate of Incorporation provides that a director of the registrant
shall not be personally liable to the registrant or its stockholders for
monetary damages for breach of his or her fiduciary duty as a director, except
for liability (1) for any breach of the director's duty of loyalty to the
registrant or its stockholders, (2) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3) for
willful or negligent conduct in paying dividends or repurchasing stock out of
other than lawfully available funds or (4) for any transaction from which the
director derives an improper personal benefit.

The registrant has entered into indemnity agreements with each of its
directors. These agreements require the registrant, among other things, to
indemnify such directors against certain liabilities that may arise by reason of
their status or service as directors, as well as to advance expenses to them as
they are incurred, provided that they undertake to repay the amount advanced if
it is ultimately determined by a court that they are not entitled to
indemnification. The indemnity agreements with each of the directors also
provides the following indemnification rights and limitations in addition to the
indemnification in the registrant's Second Amended and Restated Certificate of
Incorporation:

(1) if the registrant does not pay a claim within ninety days after written
notice has been received by the registrant, the indemnified director
may bring suit against the registrant to recover the unpaid amount of
the claim and, if successful in whole or in part, shall also be
entitled to be paid the expense of prosecuting such claim;

(2) the registrant is not liable for a claim against an indemnified
director, for which payment is made to the indemnified director, under
an insurance policy, except in respect of any excess beyond the amount
of payment under such insurance;
II-1
<PAGE> 74

(3) the registrant is not liable for a claim against an indemnified
director based upon or attributable to the indemnified director gaining
personal profit or advantage, or brought about by the dishonesty of the
indemnified director. However, the indemnified director shall be
indemnified against such claims unless a judgement or final
adjudication establishes that the indemnified director gained personal
profit or advantage to which he was not legally entitled, or committed
acts of active and deliberate dishonesty with actual dishonest purpose,
which dishonest acts were material to the cause of action,
respectively; and

(4) the registrant is not liable for an accounting of profits made from the
purchase or sale by the indemnified director of securities of the
registrant within the meaning of Section 16(b) of the Securities
Exchange Act of 1934 or similar state laws.

Reference is made to Section 145 of the General Corporation Law of the
State of Delaware which provides for indemnification of directors and officers
in certain circumstances.

The registrant has a directors' and officers' liability insurance policy.

Under the terms of the Underwriting Agreement, the underwriters have agreed
to indemnify, under certain conditions, the registrant, its directors, certain
of its officers and persons who control the registrant within the meaning of the
Securities Act of 1933.

ITEM 17. UNDERTAKINGS.

The undersigned registrant hereby undertakes:

(1) That for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to section 13(a)
or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(2) To provide to the underwriters at the closing specified in the
underwriting agreement, certificates in such denominations and registered in
such names as required by the underwriters to permit prompt delivery to each
purchaser.

(3) Insofar as indemnification for liabilities arising under the 1933
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

(4) That for purposes of determining any liability under the Securities
Act, (a) the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective and (b) each post-effective
amendment that contains a form of prospectus shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bonafide offering thereof.
