                                     PART I

ITEM 1.  BUSINESS

GENERAL

         Collagen Corporation (the "Company") designs, develops, manufactures
and markets on a worldwide basis high quality biocompatible products for the
treatment of defective, diseased, traumatized or aging human tissues with the
goal of superior physician and patient satisfaction for its products. The
Company has grown by identifying medical applications for its technology,
developing innovative products and building markets with respected healthcare
professionals, either directly or with marketing and technology partners. The
Company's core products are principally used in reconstructive and cosmetic
applications, the treatment of stress urinary incontinence, and bone repair. The
Company focuses on development of new products based upon biomaterials,
especially collagen, for sale in human healthcare markets worldwide.

CORE TECHNOLOGY

         The foundation of the Company's current business is the collagen
protein family, around which the Company has developed proprietary technology
and patented materials, processes and uses. Collagen is a family of naturally
occurring proteins that serve as the basic structural building blocks of the
tissues found in skin, cartilage, bone, tendons, ligaments, arterial walls,
nerve sheaths and other organs and tissues of the body. Collagen is present in
all mammals in higher concentration than any other protein and is quite similar
among species. There are at least fifteen types of collagen, the most common of
which is the type primarily used in the Company's commercial products and
products under development.

         The Company has developed proprietary processes to purify its bovine
(cow)-source collagen on a commercial scale and to manufacture "tissue-like"
implants from the resulting materials. These proprietary processes alter the
immunological profile of the bovine-source collagen, thus minimizing the
potential for causing an allergic reaction. The result is a purified and
sterilized fibrous collagen material that can be easily injected or implanted
into the human body.

         The potential for causing an allergic reaction arising from the
injection of bovine-source collagen is relatively low. Based on the Company's
statistics, approximately 97% of men and women tested show no allergic reaction
to a skin test and can be treated with the bovine-source collagen injection. The
3% that show an allergic reaction to the skin test display typical symptoms of
hypersensitivity, which include redness, itchiness and swelling. An additional
1-2% of the people treated develop an allergic reaction after one or more
injections.

         In August 1995, the Company added triglycerides as its second core
technology when the Company entered into a stock purchase agreement with certain
of the stockholders of LipoMatrix, Incorporated ("LipoMatrix"), a developer and
manufacturer of the Trilucent(TM) breast implant ("Trilucent implant"), to
purchase approximately 50% of the outstanding securities of LipoMatrix on a
fully diluted basis. The Company also entered into a stock purchase agreement
with certain of LipoMatrix's management and employees to purchase the remaining
10% of the outstanding securities on a fully diluted basis. This purchase
increased the Company's ownership interest in LipoMatrix from approximately 40%
to 100% of the outstanding securities on a fully diluted basis. The acquisition
of LipoMatrix, which was accounted for as a purchase, had an aggregate purchase
price of approximately $23.7 million. The Company completed the closing of the
aforementioned acquisition of LipoMatrix in January 1996.

         LipoMatrix is developing a proprietary family of biocompatible
products. Trilucent implant, which is currently being sold in eight European
countries, achieves biocompatibility by utilizing soybean oil, which has a long
history of parenteral use in human beings as a filler. Since the neutral
triglycerides of the soybean oil have the same radiodensity as human fat,
Trilucent implant provides


                                     Page 2
<PAGE>   3

a radiolucency profile superior to that seen with saline and silicone filled
implants, which may result in more meaningful mammograms to facilitate detection
of breast cancer. Laminated into the implant shell is an electronic transponder,
which will allow non-invasive implant identification. During fiscal 1997, the
Company expects to introduce the Trilucent implant in additional countries and
also begin an expanded United States clinical trial.

STRATEGY

         The Company's strategy consists of the following principal elements:

                  Expand Existing Medical Franchise. The Company has a 15-year
                  involvement with the cosmetic procedure-oriented segments of
                  the plastic surgery and dermatology markets. Medical
                  procedures for aesthetics in those markets are generally paid
                  for by the patient and therefore are not commonly subject to
                  reimbursement constraints imposed by third party payors. The
                  recently developed Trilucent implant is another example of a
                  high value product for the cosmetic and reconstructive plastic
                  surgery market. The Company's objectives include developing,
                  in-licensing, and acquiring additional products related to
                  this market.

                  Broaden Therapeutic Applications. The Company has developed
                  innovative medical products that take advantage of the
                  physical and biological properties of collagen, and has
                  developed proprietary collagen technology platforms that could
                  lead to new applications for product development. In addition,
                  The Company has implemented an "affiliate" program to expand
                  its new product development activities outside of the areas of
                  its core competence, such as vascular stents and grafts,
                  ophthalmology, and bioadhesives.

                  Enhance Biomaterials Technology. The Company has substantial
                  research, pre-clinical, clinical and regulatory expertise in
                  the development of collagen-based medical devices. The
                  Company's current objectives include improving the clinical
                  persistence of current collagen materials and reducing or
                  eliminating allergic reactions arising from the bovine source
                  of current collagen products.

         In order to facilitate the Company's overall strategy, during fiscal
1996 the Company reorganized its efforts into two operating divisions, the
Aesthetic Technologies Group and the Collagen Technologies Group. The Aesthetic
Technologies Group capitalized on the Company's long-time medical franchises in
plastic surgery, dermatology and cosmetic medicine and focuses on cosmetic and
reconstructive medical technology products. The Collagen Technologies Group, on
the other hand, is focused on the development (by the Company and its
affiliates) of products and businesses utilizing innovative collagen-based
medical technologies. Where applicable, the following discussions will be
distinguished along divisional lines.

PRODUCTS, MARKETS AND METHODS OF DISTRIBUTION

AESTHETIC TECHNOLOGIES GROUP:

         Aesthetic Technologies offers products for soft tissue augmentation,
breast reconstruction and augmentation, and stress urinary incontinence. In the
United States, the Company markets a line of injectable products (Zyderm(R) I
implant, Zyderm(R) II implant and Zyplast(R) implant) for soft tissue
augmentation of the face and will market a new product for deep facial wrinkles,
SoftForm(TM) facial implant ("SoftForm implant"), in the second half of fiscal
1997. Internationally, the Company also markets its Zyderm and Zyplast
injectable products for the face; the Trilucent implant for breast
reconstruction, augmentation and replacement of previously implanted breast
implants; and expects to market a new product for facial wrinkles, Hylaform(R)
viscoelastic gel, in the second or third quarter of fiscal 1997. In addition,
the Company's product for stress urinary incontinence,


                                     Page 3
<PAGE>   4

Contigen(R) Bard collagen implant ("Contigen implant"), is currently marketed on
a worldwide basis through its marketing partner, C.R. Bard ("Bard").

Cosmetic and Reconstructive Surgery

         Facial Implants. The Company has three principal products for the
treatment of skin contour defects: Zyderm(R) I implant, Zyderm(R) II implant
(collectively, "Zyderm implants"), and Zyplast(R) implant ("Zyplast implant"), a
cross-linked collagen product. These products are sterile devices, composed of
highly purified bovine dermal collagen, dispersed in a saline solution
containing a small amount of lidocaine and packaged in a sterile syringe. They
are injected with a fine gauge needle into depressed layers of skin to elevate
the area to surface contour. Depending on the indication and the product (or
product combination) used, most patients can achieve considerable correction in
one treatment session. The implants take on the texture and appearance of normal
host tissue and are subject to similar stresses and aging processes.
Consequently, supplemental treatments are often necessary after initial
treatment, depending on the location and original cause of the skin deformity.

         In June 1996, the Company entered into a distribution agreement with
Biomatrix, Inc. (of Ridgefield, New Jersey) to market a new injectable product,
Hylaform(R) viscoelastic gel ("Hylaform gel") for facial wrinkles. The Company
paid $5.0 million for these distribution rights. Hylaform gel has the potential
to bring the clinical benefits of injectable therapy to a new group of patients
- - those desiring "same day" treatments (no prior test dose is necessary in the
markets where the product is currently approved), as well as those who are
sensitive to bovine collagen, and potentially giving doctors and patients a
broader range of options to treat age-related wrinkles and scars. Biomatrix,
Inc. received CE mark approval for Hylaform gel in December 1995, allowing this
product to be marketed throughout Europe. The Company plans to begin marketing
Hylaform gel in Western European countries in the second or third quarter in
fiscal 1997. The Company holds exclusive marketing and distribution rights to
Hylaform gel in the United States, Canada, Australia and selected additional
markets, upon the United States Food and Drug Administration ("FDA") approval.

         Also in June 1996, the Company entered into an in-licensing agreement
with Tissue Technologies, Inc. (of San Francisco, California) to market a new
implant, SoftForm implant, for deep facial wrinkles. The SoftForm implant is
tube-shaped and composed of expanded polytetrafluoroethylene ("ePTFE"). This
product is designed to complement Zyderm and Zyplast implants as well as the
Hylaform gel products by offering a sub-dermal (under the skin), persistent
treatment to those patients with deep furrows. The SoftForm implant is expected
to offer these patients a one-time surgical treatment with minimal healing time
and if desired, is reversible. The product received marketing clearance from the
FDA in April 1996 under a 510(k) application and is anticipated to be launched
in the United States in the second half of fiscal 1997 (subject to supply of
product from Tissue Technologies, Inc.), with subsequent launches
internationally as regulatory approvals are obtained.

         The Company believes that opportunities exist in the market for its
facial implants based on: 1) the growing market for aesthetic procedures among
the "baby boomer" generation; 2) consistent overseas strength and further
geographical expansion potential; 3) an expansion in the number of new
technologies for facial rejuvenation potentially offering new features and
benefits; and 4) the Company's increased focus on patient satisfaction. While
not anticipated, factors such as negative publicity, adverse rulings by
regulatory authorities or in connection with product liability lawsuits,
introduction of competitive products by third parties or other loss of market
acceptance for the Company's principal products may significantly and adversely
affect the Company's business, financial condition and results of operations.

         Worldwide sales and worldwide unit sales of Zyderm and Zyplast implants
increased 10% and 16%, respectively, in fiscal 1996 over fiscal 1995, compared
to a 18% and 17% increase in fiscal 1995 over fiscal 1994. The United States
sales of Zyderm and Zyplast implants, which represented approximately 46% of
worldwide sales of Zyderm and Zyplast implants in fiscal 1996, increased 3% over
fiscal 1995 sales, compared to a 12% increase in fiscal 1995 over fiscal 1994.
Revenue growth 


                                     Page 4
<PAGE>   5

in fiscal 1995 was due to unit growth, while revenues in fiscal 1994 were
stimulated by a price increase. Unit sales of these implants in the United
States increased 10% in fiscal 1996 over fiscal 1995, compared to a 5% increase
in fiscal 1995 over 1994. International sales of Zyderm and Zyplast implants,
which represented approximately 54% of worldwide sales of Zyderm and Zyplast
implants in fiscal 1996, increased 16% over fiscal 1995 sales, compared to a 26%
increase in fiscal 1995 over fiscal 1994. International unit sales of these
implants increased 21% in fiscal 1996 over fiscal 1995, compared to a 29%
increase in fiscal 1995 over fiscal 1994. The Company has expanded and intends
to expand further its direct selling efforts in certain international markets.
There can be no assurance that difficulties associated with a transition to
direct marketing efforts will not have an adverse effect on the Company's
results of operations.

         The Company markets its Zyderm and Zyplast implants directly to
physicians in the United States, ten European countries, Canada, Australia and
New Zealand. The Company markets its products through distributors in all other
international markets. The Company has granted exclusive distribution rights for
Zyderm and Zyplast implants in Japan. Over the past two years, the Company has
appointed a number of new foreign distributors for its injectable collagen
products. In the United States, the Company markets primarily to the
aesthetically oriented dermatologists and plastic surgeons through a direct
sales force. Approximately 4,000 dermatologists and plastic surgeons in the
United States have purchased Zyderm and Zyplast implants from the Company in the
past year.

         The Company utilizes a variety of methods to promote its aesthetic
products to patients and physicians. To stimulate demand at the patient level,
the Company conducts consumer marketing awareness programs, such as public
relations events, health and beauty magazine advertising, direct mailing
campaigns and patient seminars. The Company's marketing efforts to physicians
consists of on-going training, education and promotional activities. Examples of
physician marketing activities may include: in-office training and education,
presence at medical meetings, and direct mail campaigns. The Company has
emphasized physician education to ensure proper training in the use of its
products and timely communication of clinical and product use information.

         The Company is committed to optimizing patient satisfaction through
various marketing programs. Market research conducted during fiscal 1996,
revealed that many patients were not receiving enough collagen material per
treatment to provide for full correction and that existing, high prices for the
product did not enable patients to purchase more. The introduction of larger
syringe fill volumes offers more material with minimal increase in cost and
injection time and an opportunity for more complete correction at only a slight
increase in treatment cost. The Company benefits from this strategy due to
increased patient satisfaction and because the marginal price charged for the
incremental material, relative to the marginal cost of the material,
economically favors the larger syringes. In addition to larger syringes, the
United States has also introduced programs which further encourage more complete
correction at the initial treatment and on an ongoing basis.

         Breast Implants. The patented Trilucent implant was developed by female
radiologists seeking a breast implant which minimized the amount of breast
tissue obscured by breast implants during mammography and was biocompatible in
the event of a leak or rupture. Trilucent implant utilizes soybean oil, which
has a long history of parenteral use in human beings as a filler. To aid in
radiolucency, the neutral triglycerides of the soybean oil were selected to have
the same radiodensity as human fat. Neither saline nor silicone-filled gel
implants have this radiolucent profile. Mammography has been demonstrated to be
important in the detection of early stage breast cancer. In 1992, the Company
participated in the formation of LipoMatrix, the developer and manufacturer of
the Trilucent implant. During fiscal 1996, the Company increased its ownership
interest in LipoMatrix from approximately 40% to 100% of the outstanding
securities on a fully diluted basis.

         By the end of fiscal 1996, Trilucent implant was being sold in eight
European countries and clinical data had been gathered on more than 200 patients
treated in Europe and over 70 patients in the United States and Canada. The
Company recorded $2.4 million in sales from Trilucent implant during fiscal
1996. During fiscal 1997, the Company expects to introduce Trilucent implant in
additional European countries and begin a pivotal United States clinical trial.
Despite lack of FDA 


                                     Page 5
<PAGE>   6

approval in the United States, consumer interest in the United States appears
high, demonstrated by telephone inquiries from both physicians and interested
consumers.

         Contigen Implant. According to the National Institutes of Health, more
than ten million Americans suffer from urinary incontinence, or the involuntary
loss of urine. While comprehensive data are not available as to the incidence of
a form of stress urinary incontinence called intrinsic sphincter deficiency
("ISD"), the Company has estimated, based upon physician survey information,
that as many as one million of these persons suffer from ISD, a poor or
nonfunctioning bladder outlet mechanism that may be helped by a locally injected
bulking agent. The Company and its marketing and distribution partner, C.R.
Bard, Inc. ("Bard"), received approval from the FDA to produce and market
Contigen implant in September 1993 for the treatment of ISD. ISD occurs among
all demographic groups, but its incidence increases with age and is twice as
high in women as men. Management and treatment alternatives have historically
included absorbent products, behavior modification, medication and surgery.
Contigen implant injections may improve stress incontinence caused by stretched
pelvic muscles from childbirth, decreased tone in the pelvic muscles supporting
the bladder (often associated with menopause and aging) and prostate surgery.

         Contigen implant is a sterile, highly purified bovine dermal collagen
that is lightly crosslinked and dispersed in a saline solution. Contigen implant
is injected into the submucosal tissues of the urethra and/or bladder neck, and
into the tissues adjacent to the urethra. The injection of Contigen implant
creates increased tissue bulk and subsequent coaptation (joining) of the
urethral lumen. After injection, the suspended collagen forms a soft cohesive
network of fibers. Over time, the implant takes on the appearance of normal host
tissue.

         Pursuant to the terms of an agreement between the Company and Bard,
Bard purchases commercial products, including Contigen implant, developed under
this agreement. In addition, the Company receives a percentage of Bard's direct
sales to physician customers. Bard holds exclusive worldwide marketing and
distribution rights to Contigen implant. Bard recently received reimbursement
codes for Contigen implant in the United Kingdom, France and Japan, clearing the
way for the product to be marketed in these countries. In the United States,
Bard is working with the Association for People with Urinary Disease to inform
incontinence suffers about the benefits of Contigen implant.

         The Company recorded approximately $6.2 million, $16.5 million, and
$16.7 million of revenue from sales of Contigen implant in fiscal 1996, 1995 and
1994, respectively. Of such revenue, $.3 million, $13.4 million and $15.9
million was derived from sales of Contigen implant to Bard and $5.9 million,
$3.1 million and $789,000 from Bard's direct sales to physicians in fiscal 1996,
1995 and 1994, respectively. (See Item 7, "Management's Discussion and Analysis
of Financial Condition and Results of Operations - Product Sales").

         For the uncertainties or risk factors that exist surrounding the
marketing and distribution of the Company's cosmetic and reconstructive
products, see Item 7, "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Factors Affecting Future Results of
Operations".

COLLAGEN TECHNOLOGIES GROUP:

         Orthopedics. The Company and its orthopedic marketing partner, Zimmer,
Inc. ("Zimmer"), a wholly-owned subsidiary of Bristol-Myers Squibb, received
approval from FDA in May 1993 to produce and market Collagraft(R) bone graft
matrix implant ("Collagraft implant"). Collagraft(R) bone graft matrix strip
("Collagraft strip"), a "premixed" formulation which is an early "ready-to-mix"
Collagraft implant formulation, was subsequently approved in January 1994.
Collagraft implant and Collagraft strip (collectively, "Collagraft bone graft
products"), when used with autogenous bone marrow, is indicated for use in acute
long bone fractures and traumatic osseous defects to provide a matrix for the
repair process of bone. Bone graft substitute eliminates the need for patients
to undergo a painful autograft bone grafting procedure, which involves
harvesting patients' own bone from another site, and it prevents the
transmission of human infectious agents and inconsistent results from allograft
procedures (bone graft supplied through a bone bank). During surgery, Collagraft
strip or Collagraft implant is mixed with the patient's own bone marrow and is
placed into the fracture site providing a scaffolding around which new bone will
grow. Medical conditions, which may require bone grafting, include acute long
bone fractures and certain tumors and cysts.

         Collagraft bone graft products are a mixture of purified fibrillar
collagen and hydroxyapatite/tricalcium phosphate ceramic ("HA/TCP") and are
supplied sterile in both a strip form (premixed) and a ready-to-mix form.
Hydroxyapatite is a substance which is biocompatible and is minimally resorbed.
Tricalcium phosphate is radiopaque, biocompatible and biodegradable. Its
degradation products can be reconstituted by the body to form new bone mineral
allowing for bone deposition.

         An agreement between the Company and Zimmer provides for the
development and distribution of collagen and other biologically-based products
for orthopedic applications. The Company will manufacture approved products and
sell them to Zimmer, which has exclusive marketing rights for Collagraft bone
graft products in the United States and Asia. The Company holds marketing rights
for Collagraft bone graft products in Europe, Canada, Africa and the Middle
East. Collagraft bone graft products are currently sold only in the United
States and the Company does not anticipate substantial sales outside the United
States for the foreseeable future. Sales of Collagraft bone graft products to
Zimmer in fiscal 1996, 1995 and 1994 totaled $3.1 million, $3.0 million and $2.7
million, respectively. Fiscal 1994 represented the first full year of sales for
Collagraft bone graft products.

         For the uncertainties or risk factors that exist surrounding the
marketing and distribution of Collagraft bone graft products, see Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations- Factors Affecting Future Results of Operations".

         Other Medical Products. During fiscal 1995, the Company expanded its
product offerings to include a line of collagen-based materials for research
applications and other custom needs. Sales of these products have not been
material in fiscal 1996 or fiscal 1995.

COMPETITION

         The medical device industry is characterized by rapidly evolving
technology and increasing competition under the recent changes in the health
care environment. The Company faces competition in each of its target product
markets.

         Zyderm and Zyplast implants. The Company faces direct and indirect
competition for its products. Internationally, direct competitors in the
injectable segment have included both approved and unapproved products primarily
derived from collagen, hyaluronic acid and silicone. In the United States,
direct competition is very small. Collagen believes it remains in the clear
leadership position in the injectable segment in its markets. Indirect
competitors to Zyderm and Zyplast implants include, among others, laser
treatments, chemical peels, fat injections, dermabrasion, botox injections and
face lifts. In addition, several companies are engaged in research and
development 


                                     Page 7
<PAGE>   8

activities examining the use of collagen and other biomaterials for the
correction of soft tissue defects. There can be no assurance that the Company
will not face increased direct and indirect competition in the soft-tissue
augmentation market.

         Trilucent implant. The principal competitors of Trilucent implant are
saline implants worldwide, and silicone gel implants outside the United States
The Company has identified Mentor Corporation and McGhan Medical Corporation,
which market both saline implants and silicone gel implants, as being the
Company's primary competitors for breast implants. These companies have greater
resources than the Company and have substantially more experience in
manufacturing and marketing in the breast implant market.

         Contigen implant. At the present time, autologous fat, silicon
micro-implants and polytetrafluorethane (Teflon paste, or PTFE) are directly
competing with Contigen implant for the treatment of stress incontinence due to
ISD. Neither silicon micro-implants nor PTFE have been approved by the FDA for
use in the United States. Other methods of treatment or amelioration of ISD may
be considered competitive with Contigen implant. These include surgery,
medication, absorbent products and behavior modification.

         Collagraft bone graft products. Bone graft substitutes currently are
used in a small fraction of bone grafting procedures. The vast majority of bone
grafting procedures currently use autograft (autologous bone) taken from the
patient's own body and allograft (bone bank bone taken from deceased donors).
Collagraft bone graft products belong to a new family of products called bone
graft substitutes. The most direct competitor to Collagraft bone graft products
is Pro-Osteon, a synthetic bone graft substitute made of a coral-like mineral. A
less direct competitor to Collagraft bone graft products is an allograft bone
product called Grafton, which is packaged in a syringe and marketed and priced
like a bone graft substitute.

         In addition, several companies and institutions are engaged in the
development of collagen-based and other materials, techniques, procedures and
products for use in medical applications anticipated to be addressed by the
Company's products, including Contigen implant and Collagraft bone graft
products. Some of these companies and institutions may have substantially
greater capital resources; research and development staffs and facilities; and
experience in conducting clinical trials, obtaining regulatory approvals, and
manufacturing and marketing products similar to those of the Company. There can
be no assurance that the Company's competitors will not succeed in developing
technologies and products that are more effective than any which have been or
may be developed by the Company or that would render the Company's technology
and products obsolete or non-competitive. There can be no assurance that such
potential competition will not have an adverse effect on the future business or
financial condition of the Company. Certain of the Company's collagen-based
products, including the Zyderm implants, were manufactured and sold pursuant to
an exclusive license from Stanford University under a United States patent,
which expired in April 1993, covering the use of native, solubilized collagen
for soft-tissue augmentation. The expiration of this patent may result in
increased competition in the market for injectable collagen implants if or when
other companies enter that market.

MANUFACTURING

         The Company manufactures its collagen-based products utilizing readily
available chemicals and enzymes. The source of its collagen is bovine (cow)
dermis. In an attempt to ensure that the hides are free from any
herd-threatening disease such as Bovine Spongiform Encephalopathy ("BSE"), the
hides are sourced from a closed herd, which requires the physical separation of
the herd from other herds, the tracking of the lineage of each animal and the
maintenance of each animal under a veterinarian program. The Company obtains
HA/TCP solely from Zimmer for the manufacture of Collagraft implant. The Company
believes that the supply of raw materials and processing materials for its
manufacturing operations is and will continue to be adequate for the foreseeable
future and that such materials can be available from other sources.


                                     Page 8
<PAGE>   9

         The Company's principal products have various refrigerated shelf lives
of 30 to 36 months. The Company typically ships products to physicians as orders
are received on an express delivery basis, and has no material backlog. It is
the Company's policy to maintain levels of finished goods inventory adequate to
allow for the expeditious handling of orders received. The Company believes its
physician customers typically purchase products on an as-needed basis, while
distributor customers purchase products based on inventory stocking levels.

         The Company manufactures its collagen-based products in its Fremont,
California facility. While the Company has not experienced any disruptions in
its manufacturing schedule during the last two fiscal years and does not
anticipate any delays in the future, it is possible that the Company may
experience disruptions in its manufacturing schedule as it continues to
manufacture products in increasingly larger quantities and with new process
improvements. The Company's manufacturing facilities are subject to regulatory
requirements and periodic inspection by regulatory authorities, such as the FDA
in the United States, and in countries such as the United Kingdom, outside the
United States. In June 1995, the Company was inspected by TUV Product Services
to ensure that the Company's products met the requirements of the European
Medical Directive. After the completion of the inspection, the Company was
certified to place the CE Mark on its product packages and to sell its products
directly to physicians in most European countries.

         LipoMatrix produces the Trilucent implant in Neuchatel, Switzerland,
where it maintains a facility with a quality system meeting the requirements of
ISO9001 and EN46001 quality standards as certified by TUV and SQS Product
Services in December 1994. Such certification ensures that the products conform
to the essential requirements of the European Medical Directive and allows the
CE marking to be placed on the product packages. LipoMatrix may experience
disruptions in manufacturing as it manufactures increasingly larger quantities
of products. In addition, it may experience a significant shortage of
manufacturing capacity if its facility fails to operate as planned.

PRODUCT RESEARCH AND DEVELOPMENT

         The Company maintains an active program of technology and new product
development. The Company intends to continue to devote a significant portion of
revenues to research and product development activities throughout its product
lines to generate significant returns to stockholders. Research and Development
("R & D") expenses for the Company totaled $12.2 million, $9.9 million and $9.4
million in fiscal 1996, 1995 and 1994, respectively. R & D expenses represented
18%, 14% and 15% of product sales for those years.

         The Company's focus has been in four major areas:  1) new injectable 
products and enhancements to existing products for the treatment of skin contour
defects, 2) Trilucent implant an enhancements, 3) investment in affiliated 
companies working on a wide variety of medical indications, and 4) joint 
development programs focused on the orthopedics area.

         The soft tissue augmentation program has concentrated on improvements
relating to two performance criteria-duration of treatment benefit and the
elimination of local inflammatory reactions. The Company is exploring several
formulations to improve persistence of its Zyderm and Zyplast implants and is
also investigating human collagen as an alternative for the potential collagen
patients who are allergic to bovine-based products or who elect to minimize this
possibility of an allergic reaction to the product. Two potential sources of
human collagen are being explored simultaneously: placental-sourced human
collagen and recombinant human collagen through transgenic animals and yeast.
The Company has an ongoing collaboration with IMEDEX, a subsidiary of
Rhone-Poulenc S.A., to develop new products based on the use of human
placental-collagen. In addition, the Company has made an equity investment in
and is actively collaborating with Pharming, B.V. for the purpose of developing
recombinant human collagen.

         As an enhancement to the Company's business in the area of cosmetic and
reconstructive surgery, the Company has added LipoMatrix's breast implant,
Trilucent implant, to its product line. Trilucent implants are designed and
developed at Lipomatrix' Neuchatel, Switzerland facility in 


                                     Page 9
<PAGE>   10

accordance with EN46001 and ISO9001 and other international standards, including
risk analysis, technical files, validation and testing.

         As part of the Company's growing orthopedics business, the Company
acquired approximately 12% of and entered into a collaborative product
development agreement, related to developing resorbable or partially resorbable
mechanical tissue-fixation devices for applications in orthopedic tissue
repairs, with Innovasive Devices, Inc. during fiscal 1996. In addition, the
Company is investigating the use of other collagen based biomaterials for use in
a variety of orthopedic indications and continues to support its Collagraft bone
graft products, which is being marketed and sold in the United States by Zimmer.

         With regards to investing in new ideas and products, the Company has an
active program for developing new products through affiliated companies in which
the Company makes equity and debt investments. The Company believes the
formation of new companies allows each to focus its technology on select market
segments, to bring products efficiently to market and to advance proprietary
know-how at a rapid rate. However, there can be no assurance that these
investments will result in positive returns nor can there be any assurance on
the timing of any return on such investments. The Company's affiliate
investments consist of the following principal elements:

                  New Products in New Market Segments. In fiscal 1994, the
                  Company, together with Target, and Celtrix Pharmaceuticals,
                  Inc., formed Prograft Medical Inc. ("Prograft"). Prograft
                  focuses on the development of proprietary vascular grafts,
                  vascular stents and vascular stent-graft combinations, which
                  may use certain of the Company's biomaterials, for use in the
                  repair and replacement of diseased and damaged blood vessels.
                  As of June 30, 1996, the Company held approximately 21% of the
                  equity of, and has also entered into license and supply
                  agreements with, Prograft. In fiscal 1994, the Company and its
                  founder, Dr. Rodney Perkins, formed Cohesion Corporation
                  (formerly Otogen Corporation), a start-up company which is
                  currently developing surgical tissue adhesives for use in
                  general surgical applications in such areas as plastic
                  surgery, neurology, thoracic surgery and cardiology. In fiscal
                  1996, the Company increased its ownership position in Cohesion
                  Corporation from approximately 40% to 81%. Cohesion
                  Corporation anticipates that its lead product will begin
                  clinical evaluation in the third or fourth quarter of fiscal
                  1997. In fiscal 1993, the Company participated in the
                  formation of CollOptics, Inc. to develop collagen-based
                  lenticules, which are custom-made contact lenses for
                  refractive errors. The Company currently holds a 47% ownership
                  interest in CollOptics, Inc.

                  Access to New Technology. In fiscal 1996, the Company has made
                  an equity investment in and is actively collaborating with
                  Pharming, B.V. for the purpose of developing recombinant human
                  collagen. This technology could provide the Company with a
                  source of recombinant human collagen that is chemically
                  identical to native human collagen. The Company and Pharming,
                  B.V. will attempt to produce collagen in the milk of dairy
                  cattle.

         For the uncertainties or risk factors that exist with the Company's
investments in affiliate companies, see Item 7, "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Factors Affecting
Future Results of Operations".

PATENTS AND PROPRIETARY TECHNOLOGY

         The Company depends substantially upon its proprietary technological
expertise in the extraction, purification, and formulation of collagen-based
materials and other biomaterials into biomedical products. The Company seeks
patents on inventions concerning novel manufacturing processes, composition of
matter, and applications for its proprietary biomaterials. At present, the
Company holds over 60 issued patents and numerous patent applications. The
Company's subsidiary, LipoMatrix, also holds several issued patents and patent
applications concerning 


                                    Page 10
<PAGE>   11

Trilucent implant. The Company's license from Stanford University under a United
States patent covering the use of native, solubilized collagen for soft tissue
augmentation, expired in April 1993.

         Patent-related litigation is an increasing risk in the medical device
industry. There can be no assurance the Company will be successful in the future
in obtaining patents or license rights, that patents will be issued for the
Company's current patent applications, that the Company will develop additional
proprietary technology that is patentable, that any issued patents will provide
the Company with any competitive advantages or will not be challenged by third
parties, or that patents of others will not have an adverse effect on the
Company. No assurance can be given that the Company's processes or products will
not infringe patents or proprietary rights of others or that any licenses
required under any such patents or proprietary rights would be made available on
terms acceptable to the Company. If the Company does not obtain such licenses,
it could encounter delays in product introductions while it attempts to design
around such patents, or it could find that the manufacture, sale or use of
products requiring such licenses could be enjoined. In addition, the Company
could incur substantial costs in defending itself in suits brought against the
Company on such patents or in bringing suits to protect the Company's patents
against infringement.

         The Company relies upon trade secret protection for certain unpatented
aspects of other proprietary technology. There is no assurance that others will
not independently develop or otherwise acquire substantially equivalent
proprietary information or techniques, others will not otherwise gain access to
the Company's proprietary technology or disclose such technology, or the Company
can meaningfully protect its trade secrets.

         The Company typically requires its employees and consultants to execute
appropriate confidentiality and proprietary information agreements upon the
commencement of employment or consulting relationship with the Company. These
agreements generally provide that all confidential information developed or made
known to the individual by the Company during the course of the individual's
relationship with the Company, is to be kept confidential and not disclosed to
third parties, except in specific circumstances. The agreements generally
provide that all inventions conceived by the individual in the course of
rendering services to the Company shall be the exclusive property of the
Company; however, certain of the Company's agreements with consultants, who
typically are employed on a full-time basis by academic institutions or
hospitals, do not contain assignment of invention provisions. There can be no
assurance, however, that these agreements will provide meaningful protection or
adequate remedies for the Company in the event of unauthorized use, transfer or
disclosure of such information or inventions.

         The Company holds several registered trademarks in the United States
and a number of foreign countries and vigorously pursues the protection of its
trademarks and service marks, whether registered or not.

GOVERNMENT REGULATION

         The Company's manufacturing activities and products sold in the United
States are subject to extensive and rigorous regulations by the FDA and by
comparable agencies in certain foreign countries where these products are
manufactured or distributed. The FDA regulates the manufacture, clinical
research and sale of medical devices, including labeling, advertising and
recordkeeping. The Company's primary products are classified as Class III
medical devices, which require pre-market approval from the FDA. All of the
Company's products described in "Products, Markets and Methods of Distribution,"
other than Trilucent implant and Hylaform gel, have been approved for sale in
the United States. Biomatrix, Inc. submitted a Pre-Market Approval application
in August 1995 for Hylaform gel and FDA approval of such product is currently
pending. Medical products whose market applications have not yet been approved
by the FDA may only be exported from the United States with the specific
approval of the FDA. There can be no assurance that the FDA will choose to
characterize future products as medical devices rather than drugs or biologics.
Any such change in FDA characterization would potentially lengthen and increase
the cost of the approval process.


                                    Page 11
<PAGE>   12

         The Company's clinical research program has been and remains subject to
the Investigational Device Exemption ("IDE") regulations of the FDA. These
regulations govern many important aspects of the clinical investigation of
medical products, including obtaining informed consent from clinical subjects,
securing the approval of an Institutional Review Board and maintaining required
documentation relating to the conduct of the investigational study. In addition,
these regulations may require that the Company obtain approval from the FDA
prior to the commencement of clinical investigations of new products or of
expanded applications for commercially available products. The Company
anticipates that during fiscal 1997 it will commence United States clinical
trials for Trilucent implant pursuant to an FDA-approved IDE.

         Compliance with current Good Manufacturing Practices regulations is
necessary to receive FDA approval to market new products and to continue to
market current products. The Company's manufacturing, quality control and
quality assurance procedures and documentation have been inspected and evaluated
by the FDA on a periodic basis since February 1981.

         The continuing trend of more stringent FDA oversight in product
clearance and enforcement activities has caused medical device manufacturers to
experience longer approval cycles, more uncertainty, greater risk and higher
expenses. Failure to obtain, or delays in obtaining, the required regulatory
approvals for new products, including Trilucent implant, could adversely affect
the Company, as could product recalls. In addition, there can be no assurance
that the FDA will give approval to the Company to market its current products
for broader or different applications, or that it will grant approval with
respect to separate product applications which represent extensions of the basic
collagen technology, or that existing approvals will not be withdrawn. Further,
changes in governmental reimbursement systems, pursuant to which hospitals and
physicians are reimbursed for medical procedures at a fixed rate according to
diagnosis-related groups or other reimbursements, could have an economic impact
on the purchase and use of medical devices. A material decrease in current
reimbursement levels for treatment of ISD could have a material adverse effect
on the Company's business.

         Sales of medical devices outside the United States are subject to
foreign regulatory requirements that vary widely from country to country. The
time required to obtain clearance required by foreign countries may be longer or
shorter than that required for FDA clearance, and requirements for licensing may
differ significantly from FDA requirements. Some countries have historically
permitted human studies earlier in the product development cycle than
regulations in the United States permit. Other countries, such as Japan, have
requirements similar to those of the United States. This disparity in the
regulation of medical devices may result in more rapid product clearance in
certain countries than in others.

EMPLOYEES

         As of September 1, 1996, the Company employed 379 employees, of which
53 were engaged in research and development, 125 were engaged in sales and
marketing, 128 were involved in production and quality control, and 73 were
engaged in finance and administration. None of the Company's employees is
covered by a collective bargaining agreement. The Company also has a Board of
Scientific Advisors which currently consists of five scientists, each of whom is
prominent in his field and serves as a professor at a major academic
institution. The Company has a consulting agreement with each advisor which
ranges from two to three years.

ITEM 2.  PROPERTIES

         The Company's principal executive, marketing, and research activities
are presently located in three buildings in Palo Alto, California. The Company
has leased these buildings under various leases that expire between June 1999
and November 2004 and contain renewal options. The Company leases a total of
approximately 77,000 square feet, of which the Company subleases 22,000 square
feet to several of its affiliate companies. The Company's international
facilities, which amount to approximately 20,000 square feet in total, are
leased under various leases and contain renewal options.

         In 1989, the Company completed a sale-leaseback transaction relating to
its 50,000 square feet manufacturing facility in Fremont, California. The
facility lease term extends for fifteen years with four five-year renewal
options. The Company commenced commercial manufacturing in this facility in
November 1990. In addition, the Company leases approximately 11,000 square feet
of warehouse space in Fremont, California.

         LipoMatrix's administrative, research and development, manufacturing
and quality assurance functions are located in a 20,000 square foot facility in
Neuchatel, Switzerland. The facility is leased under various leases, which
expire between March 1997 and December 2005 and contain renewal options.

         The Company believes that its facilities are adequate to meet its
requirements for at least the next twelve months.


ITEM 3.  LEGAL PROCEEDINGS

         The Company is involved in various legal actions arising in the
ordinary course of business, the majority of which involve product liability
claims. While the outcome of such matters is currently not determinable, it is
management's opinion that these matters, including the matters 


                                    Page 14
<PAGE>   15

discussed below, will not have a material adverse effect on the Company's future
consolidated financial position, results of operations or cash flows.

         The Company faces an inherent business risk of exposure to product
liability claims alleging that the use of the Company's technology or products
has resulted in adverse effects. Such risks will exist even with respect to
those products that have received or in the future may receive regulatory
approval for commercial sale. There can be no assurance that the Company will
avoid significant product liability claims and negative publicity. Furthermore,
there can be no assurance that present insurance coverage will be adequate or
that adequate insurance coverage will remain available at acceptable costs, if
at all, or that a product liability claim or recall would not adversely affect
the future business or financial condition of the Company. It is possible that
adverse product liability actions could negatively affect the Company's ability
to obtain and maintain regulatory approval for its products.

         In light of regulatory investigations surrounding product safety, the
Company announced in September 1991 that it will indemnify physicians against
damages and legal fees arising from lawsuits brought to a jury trial alleging a
link between collagen injections and Polymyositis and Dermatomyositis. To date,
there has not been any impact of this indemnification on the Company's results
of operations. There can be no assurance, however, that any future such claims
would not have a material adverse effect on the Company's operating results.
Because the indemnification program has never been utilized, the Company may
discontinue the program in the future.

         On December 21, 1994, the Company filed suit in Santa Clara County
Superior Court against Matrix Pharmaceutical, Inc., ("Matrix") alleging fraud,
misappropriation of trade secrets, unfair competition, breach of fiduciary duty,
inducing breach of contract, breach of duty of loyalty and tortious
interference. The Company alleges that Matrix, which uses collagen for certain
drug delivery applications, unlawfully obtained the Company's confidential and
proprietary information relating to the Company's products and operations by
hiring ten former employees that the Company alleges had access to or were
knowledgeable about the Company's proprietary information. On February 12, 1995,
Matrix denied the Company's allegations and filed a cross-complaint charging the
Company with, among other things, unfair competition, defamation and restraint
of trade. Matrix also has requested certain declaratory relief. Howard Palefsky,
Chairman of the Board and Chief Executive Officer of Collagen, was personally
named as an additional defendant to the Matrix defamation charge. The Company
intends to vigorously contest Matrix's charges. In September 1995, the Company
filed an amended complaint naming two additional former employees, and alleging
the acquisition of additional proprietary information obtained unlawfully. On
November 3, 1995, those two additional former employees filed a cross-complaint
against the Company and Mr. Palefsky, claiming damages for, among other things,
libel, invasion of privacy and intentional infliction of emotional distress. The
Company and Matrix have been engaged in discovery since the filing of this
lawsuit.

Corporation during its fourth fiscal quarter ended June 30, 1996.

 (1) As a result of the sale of portions of the Company's shares of Target
     Therapeutics, Inc. ("Target"), the Company's ownership position in Target
     decreased to below 50% in December 1992. The first five months in fiscal
     1996 and 1995, 1994 and 1993 financial information is presented with Target
     accounted for under the equity method. All previous years contain
     consolidated results of Target (see Notes 1 and 4 to the Consolidated
     Financial Statements). Gains from sales of portions of the Company's
     investment in Target contributed $85.8 million, $6.0 million, $20.3
     million, and $10.2 million to fiscal 1996, 1995, 1993 and 1992 pre-tax
     earnings, respectively.

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


THE COMPANY

         Except for the historical information contained herein, the matters
discussed in this report are forward-looking statements that involve certain
risks and uncertainties that could cause actual results 


                                    Page 17
<PAGE>   18

to differ materially from those in the forward-looking statements. Potential
risks and uncertainties include, without limitation, those mentioned in this
report and, in particular the factors described below under "Factors That May
Affect Future Results of Operations".

         Collagen Corporation (the "Company") is a technology-based company that
develops, manufactures and markets biomedical devices for the treatment of
defective, diseased, traumatized or aging human tissues.

         The Company's revenues have been derived primarily from the sale of
products used in reconstructive and cosmetic applications for the face, the
treatment of stress urinary incontinence, and in bone repair. The Company
markets its reconstructive and cosmetic products directly and through a network
of international distributors and its stress urinary incontinence and bone
repair products through marketing partners.


ACQUISITIONS AND INVESTMENTS

         On August 22, 1995, as part of the Company's strategy to expand its
marketing franchise in aesthetic and reconstructive technology, the Company
entered into a stock purchase agreement ("Agreement") with certain of the
stockholders of LipoMatrix, Incorporated ("LipoMatrix"), a developer and
manufacturer of the Trilucent(TM) breast implant ("Trilucent implant"), to
purchase approximately 50% of the outstanding securities of LipoMatrix on a
fully diluted basis. The Company also entered into a stock purchase agreement
with certain of LipoMatrix's management and employees to purchase the remaining
10% of the outstanding securities on a fully diluted basis. This purchase
increased the Company's ownership interest in LipoMatrix from approximately 40%
to 100% of the outstanding securities on a fully diluted basis. The acquisition
of LipoMatrix, which was accounted for as a purchase, had an aggregate purchase
price of approximately $23.7 million (See Note 6 to the Consolidated Financial
Statements). The Company completed the closing of the aforementioned acquisition
of LipoMatrix in January 1996.

         In October 1995, the Company purchased approximately 844,000 shares of
common stock or approximately 12% in Innovasive Devices, Inc. (of Marlborough,
Massachusetts) and entered into a collaborative product development agreement
with Innovasive Devices, Inc. ("Innovasive Devices"). The Company and Innovasive
Devices are collaborating to develop certain resorbable or partially resorbable
mechanical tissue-fixation devices utilizing collagen-based biomaterials for
applications in orthopedic tissue repairs. Innovasive Devices is a company that
develops, manufactures, and markets tissue and bone reattachment systems which
are particularly relevant to the sports medicine and arthroscopy segments of the
orthopedic surgery market.

         Seeking to capitalize on recent technical successes in expressing
recombinant collagen in mouse milk, in February 1996, the Company made an
additional equity investment of approximately $4.5 million in Pharming, B.V. (of
The Netherlands), bringing the Company's ownership percentage in Pharming, B.V.
to approximately 12%. Pharming, B.V. is dedicated to the development and
worldwide commercialization of human health care products produced in transgenic
animals. Collagen and Pharming, B.V. will attempt to produce collagen in the
milk of dairy cattle.

         The Company increased its ownership position in Cohesion Corporation
(of Palo Alto, California) from approximately 40% to 81% on May 29, 1996.
Cohesion Corporation is a privately-held company that is developing novel
biomaterials with superior performance characteristics in the areas of tissue
adhesives, hemostats, biosealants, and adhesion prevention. In connection with
the Company's investment in Cohesion Corporation, $3.0 million was allocated to
in-process research and development, which was expensed at the time of the
investment. Cohesion Corporation anticipates that its lead product will begin
clinical evaluation in the third or fourth quarter of fiscal 1997.

         On June 4, 1996, the Company entered into an in-licensing agreement
with Tissue Technologies, Inc. (of San Francisco, California) to market a new
implant for deep facial wrinkles. 



                                    Page 18
<PAGE>   19

The product had received marketing clearance from the United States Food and
Drug Administration ("FDA") in April 1996 under a 510(K) application and is
anticipated to be launched in the United States in the second half of fiscal
1997, with subsequent launches internationally as regulatory approvals are
obtained.

         Additionally, on June 17, 1996, the Company entered into a distribution
agreement with Biomatrix, Inc. (of Ridgefield, New Jersey) to market a new
injectable product, Hylaform(R) viscoelastic gel for facial wrinkles. The
Company paid $5.0 million for these distribution rights. Biomatrix, Inc.
received CE mark approval for Hylaform(R) viscoelastic gel in December 1995,
allowing this product to be marketed throughout Europe. The Company plans to
begin marketing Hylaform(R) viscoelastic gel outside the United States in the
second or third quarter in fiscal 1997.

         In addition to internal research and development ("R&D") and joint
product development arrangements, the Company has an active program for
developing new products through affiliated companies in which the Company makes
equity and debt investments. The Company believes the formation of new companies
allows each to focus its technology on select market segments to bring products
to market efficiently and to expand its proprietary knowledge.

PRODUCT SALES. Product sales of $68.7 million in fiscal 1996 decreased $2.9
million or 4% versus fiscal 1995 sales of $71.6 million, which in turn increased
$7.0 million or 11% over fiscal 1994 sales of $64.6 million. The $2.9 million
decrease in fiscal 1996 over 1995 was primarily due to a decrease in shipments
of Contigen(R) Bard(R) collagen implant ("Contigen implant"), partially offset
by a $7.4 million increase in worldwide sales of plastic surgery and
dermatological products. The $7.0 million increase in fiscal 1995 over 1994 was
primarily due to growth in worldwide sales of plastic surgery and dermatological
products.

       The table below outlines the two components of product sales for Contigen
implant over the three year period.

</TABLE>

         The Company did not record any income from Bard's direct sales to
physician customers until fiscal 1994 as Bard's sales to customers commenced
late in the second quarter of fiscal 1994. Fiscal 1995 sales to Bard represent
minimum shipment levels made in accordance with an agreement between Bard and
the Company. For fiscal 1996 there was no agreement for sales to Bard. At June
30, 1995, Bard had a significant inventory of these products and as a result,
the Company made minimal shipments to Bard in fiscal 1996 as expected. Future
income from shipments of Contigen(R) implant to Bard is expected to resume in
the third or fourth quarter of fiscal 1997.

         Worldwide sales of the Company's other aesthetic and reconstructive
products in fiscal 1996 were $58.9 million or 14% higher than fiscal 1995 sales
of $51.5 million, compared to a 18% increase in fiscal 1995 over fiscal 1994
sales of $43.5 million. The increase in sales in fiscal 1996 was attributable in
part to the launch of the Trilucent implant (a triglyceride-filled mammary
implant) in Europe. The Company believes that the increase in sales in fiscal
1995 was due to a combination of a price increase and a growth in demand.
International sales in dollars were impacted favorably by exchange rates by
$457,000 in fiscal 1996 and $1.6 million in fiscal 1995. The Company anticipates
continued growth in future worldwide product sales in dollars in these markets.

         Worldwide unit sales of the Company's other aesthetic and
reconstructive products increased approximately 16% in fiscal 1996 over fiscal
1995 and 17% in fiscal 1995 over 1994. The Company believes the improved
performance in both fiscal 1996 and 1995 was a result of strong distributor
sales, especially in Japan, successful international marketing and public
relations efforts by the Company's subsidiaries, the launch of new syringe
configurations, and continued improving economic conditions in Europe.
Domestically, implementation of United States marketing programs designed to
both increase average treatment volume per patient and to attract and retain new
and existing patients, have favorably impacted overall unit sales.

         Collagraft(R) bone graft matrix and Collagraft(R) bone graft matrix
strip ("Collagraft bone graft products") are for the treatment of acute long
bone fractures and traumatic osseous defects. Sales of Collagraft implant and
Collagraft strip to Zimmer, Inc. totaled $3.1 million, $3.0 million and $2.7
million in fiscal years 1996, 1995 and 1994, respectively. Fiscal 1994
represented the first full fiscal year of sales of Collagraft bone graft
products.

         A number of uncertainties exist surrounding the marketing and
distribution of Contigen implant and Collagraft bone graft products. The
Company's primary means of distribution for these products is through third
party firms, Bard, in the case of Contigen implant, and Zimmer, in the case of
Collagraft bone graft products. The Company's business and financial results
could be adversely affected in the event that either or both of these parties
are unable to market the products effectively, anticipate customer demand
accurately, or effectively manage industry-wide pricing and cost containment
pressures in health care.

OTHER REVENUE. Other revenue in fiscal years 1996, 1995 and 1994 consisted of
milestone payments of $2.0 million, $1.0 million and $1.0 million, respectively,
from Bard in accordance with an agreement between the Company and Bard. The
final milestone payment of $2.0 million was paid to the Company on September 30,
1995.

COST OF SALES. Cost of sales as a percentage of product sales averaged 28%, 26%
and 29% in fiscal 1996, 1995 and 1994, respectively. The increase in fiscal 1996
over 1995 in cost of sales as a

                                    Page 20
<PAGE>   21

percentage of product sales was primarily due to the inclusion of start up
manufacturing costs of Trilucent implant, which continues to be launched in
additional countries. Unit cost of manufacturing for collagen-based products was
considerably higher in fiscal 1996 than in fiscal 1995 due to decreased
production volumes, primarily of Contigen implant. The decrease in cost of sales
as a percentage of product sales in fiscal 1995 over 1994 was primarily due to
increased product revenues resulting from income received from Bard's direct
sales of Contigen implant to physician customers as well as the favorable impact
of foreign exchange rates on international product sales in fiscal 1995.
Additionally, cost of sales reflected slightly lower unit costs due to increased
production volumes in fiscal 1995 and 1994, primarily from Contigen implant.

         Due to the high fixed costs of the Company's manufacturing facility,
unit cost of manufacturing is expected to remain highly dependent on the level
of output at the Company's manufacturing facility, which is heavily dependent on
production of Contigen implant. The Company anticipates that overall unit costs
will be lower in fiscal 1997 compared to fiscal 1996 as a result of the expected
resumption of Contigen implant shipments to Bard beginning in the third or
fourth quarter of fiscal 1997 and the increased production volumes of Trilucent
implant. In addition cost of sales as a percentage of sales is also contingent
on the product mix of future sales for which demand and pricing characteristics
may vary.

SG&A. Selling, general and administrative ("SG&A") expenses totaled $39.0
million in fiscal 1996, $32.2 million in fiscal 1995 and $28.6 million in fiscal
1994, representing 57%, 45%, and 44% of product sales, respectively. SG&A
expenses increased by $6.8 million, or 21% in fiscal 1996 over fiscal 1995,
primarily due to the operating results of LipoMatrix and amortization resulting
from the acquisition of LipoMatrix. Additionally, higher United States
advertising and public relation campaign expenses, costs of launching Trilucent
implant in Europe, higher international spending related to an overall increase
in sales and increased international infrastructure, contributed to this
increase. The $3.5 million, or 12% increase in fiscal 1995 over fiscal 1994 was
primarily due to higher international sales and marketing spending, including
the unfavorable impact of foreign exchange rates. The Company expects SG&A
expenses in fiscal 1997, both in absolute dollars and as a percentage of product
sales, to be at levels higher than those of fiscal 1996, primarily due to the
continued costs of launching Trilucent implant in additional countries.

R&D. R&D expenses, which include expenditures for regulatory compliance, were
$12.2 million (18% of product sales) in fiscal 1996, $9.9 million (14% of
product sales) in fiscal 1995, and $9.4 million (15% of product sales) in fiscal
1994. The increase in R&D spending in fiscal 1996 over 1995 was primarily
attributable to R&D spending incurred by LipoMatrix, partially offset by
completion of soft tissue programs and lower expenses related to ISO 9000
certification. The R&D spending increase in fiscal 1995 over fiscal 1994 was
primarily attributable to advancements in soft tissue programs, including
clinical trials for Zyplast(R) II Implant (a concentrated collagen material for
soft tissue augmentation), which the Company decided to discontinue at the end
of fiscal 1995. The Company expects internal R&D spending to increase
significantly in fiscal 1997.

PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT. The charge for purchased
in-process research and development ("in-process R&D") of $17.8 million in
fiscal 1996 was due to the $14.8 million non-recurring charge related to the
acquisition of LipoMatrix and the $3.0 million non-recurring charge related to
the increase in ownership from approximately 40% to 81% in Cohesion Corporation.

OPERATING INCOME. Operating loss was $17.6 million in fiscal 1996, compared to
operating income of $11.9 million in fiscal 1995 and operating income of $8.6
million in fiscal 1994. The loss in the fiscal 1996 was primarily due to the
acquisition-related, non-recurring, in-process R&D charges of $17.8 million
related to LipoMatrix and Cohesion Corporation. Excluding these acquisition
related, non-recurring R&D charges, operating income would have been
approximately $208,000 in fiscal 1996. Additionally, the decrease in operating
income in fiscal 1996 was to a large extent due to the inclusion of the
operating expenses of LipoMatrix subsequent to the acquisition in August 1995.
The 38% increase in operating income in fiscal 1995 over 1994 was attributable
primarily to improved sales of other aesthetic and reconstructive products,
partially offset by increased SG&A expenses. The improvement in operating income
in fiscal 1995 over 1994 was primarily the result 

                                    Page 21
<PAGE>   22

of increased sales of Contigen implant and Collagraft bone graft products, as
well as decreased SG&A expenses.

IMPACT OF FOREIGN EXCHANGE RATES. The impact of foreign exchange rates from
fiscal 1995 to 1996 resulted in an increase in revenue of approximately $457,000
and an increase in operating expenses of approximately $440,000, resulting in a
net increase in operating income of approximately $17,000 on equivalent local
currency basis, compared to an increase in revenue of approximately $1.6 million
and an increase in operating expenses of approximately $1.1 million, resulting
in a net increase in operating income of approximately $500,000 from fiscal 1994
to fiscal 1995.

GAIN ON INVESTMENTS. In fiscal 1996, the Company recorded a net gain on
investments of $82.1 million (pre-tax gain of approximately $86.1 million
partially offset by the recording of investment reserves of an aggregate of $4.0
million to write-down the carrying value of certain equity investments due to a
decline in value determined to be other than temporary), resulting primarily
from the sale of 1,792,000 shares of common stock of Target Therapeutics, Inc.
("Target"). In fiscal 1995, the Company sold 245,000 shares of common stock of
Target for a pre-tax gain of approximately $6.0 million. In addition, the
Company recorded an investment reserve of $925,000 to write-down the carrying
value of certain equity investments due to a decline in value determined to be
other than temporary. In fiscal 1994, the Company did not sell any shares of
common stock of Target.

EQUITY IN EARNINGS/LOSSES OF AFFILIATE COMPANIES. Equity in earnings of Target
was $1.4 million in fiscal 1996 compared to $2.4 million and $1.7 million in
fiscal 1995 and 1994, respectively. Equity in Target's earnings decreased in
1996 over 1995 due to the Company's ownership percentage falling from
approximately 29% at June 30, 1995 to approximately 11% at June 30, 1996. In
December 1995, when the Company's ownership interest fell below 20%, the Company
changed from the equity to the cost method of accounting for its investment in
Target. Equity in Target's earnings increased in fiscal 1995 over 1994 due to
increased earnings of Target, partially offset by the Company's reduced
ownership interest resulting from the sale of Target shares.

         Equity in losses of other affiliate companies in fiscal 1996 was $2.3
million compared to $3.6 million in fiscal 1995 and $1.9 million in fiscal 1994.
The decrease in equity in other affiliates' losses in fiscal 1996 over 1995 was
primarily due to lower LipoMatrix equity losses as a result of the Company
acquiring LipoMatrix in August 1995, partially offset by increased losses of
other affiliates. Equity in affiliates' losses increased in fiscal 1995 over
1994 due to additional investments made in affiliate companies. The Company
intends to continue to expand its new product development activities through
more equity investments in or loans to affiliate companies during fiscal year
1997. These affiliate companies typically are in an early stage of development
and may be expected to incur substantial losses which in turn will have an
adverse effect on the Company's operating results. There can be no assurance
that these investments will result in positive returns nor can there be any
assurance on the timing of any return on investment, or that the Company will
not lose its entire investment.

INTEREST INCOME AND EXPENSE. Interest income was $1,145,000 in fiscal 1996,
$487,000 in fiscal 1995 and $510,000 in fiscal 1994. The increase in fiscal 1996
over 1995 was primarily due to higher average short-term investment balances,
resulting primarily from the sale of Target stock, and higher interest rates.
The decrease in fiscal 1995 over fiscal 1994 was due to lower average investment
balances, partially offset by higher interest rates.

         Interest expense of $296,00 in fiscal 1996 was related primarily to
borrowings under the $15 million revolving credit facility and the $3.3 million
credit facility (4.1 million Swiss Francs) established by LipoMatrix prior to
its acquisition by the Company. (See Note 7 of the Consolidated Financial
Statements.) Interest expense of $91,000 in fiscal 1995 was related primarily to
the revolving credit facility.

                                    Page 22
<PAGE>   23

INCOME TAXES. The Company's effective income tax rate was approximately 46% for
fiscal 1996 (excluding the impact of the purchased in-process research and
development charges for which no tax benefit is available) compared to 46% for
fiscal 1995 and 44% for fiscal 1994. The 46% effective tax rate in fiscal 1996
was higher than the statutory rate due primarily to state taxes, consolidated
losses in foreign subsidiaries and increased write-downs of certain equity
investments for which no tax benefit is available currently. The increase in
fiscal 1995 compared to fiscal 1994 is due primarily to increased non-deductible
equity in losses of affiliates and investment reserves.

LIQUIDITY AND CAPITAL RESOURCES

         At June 30, 1996, the Company's cash, cash equivalents and short-term
investments were $25.4 million compared to $9.4 million at June 30, 1995. Net
cash used in operating activities was $36.3 million for fiscal 1996, compared
with $10.3 million of net cash provided by operating activities for fiscal 1995.

         For fiscal 1996, the $36.3 million of net cash used in operating
activities was mainly attributable to $39.6 million of estimated tax payments
made during the year, of which a significant portion was related to estimated
taxes due on the sales of Target stock. Net cash provided by investing and
financing activities of approximately $51.8 million was primarily due to a
pre-tax gain of approximately $85.8 million ($97.5 million proceeds less cost
basis of $11.7 million) from the sale of 1,792,000 shares of common stock of
Target by the Company during fiscal 1996, $5.5 million received from credit
facilities, and $1.0 million from the issuance of approximately 56,000 shares of
the Company's common stock, partially offset by the net payments of
approximately $21.7 million for the acquisition of LipoMatrix, payments of
approximately $14.3 million for additional investments in and loans to
affiliates, payments of approximately $5.5 million to repurchase 300,000 shares
of the Company's common stock at an average acquisition price of approximately
$18.00 per share, payment of $5.0 million made to Biomatrix for the distribution
rights to market Hylaform viscoelastic gel, capital expenditures of
approximately $2.6 million, net payments of $1.3 million made to increase the
Company's ownership in Cohesion Corporation from 40% to approximately 81%, and
the payments of aggregate cash dividends of approximately $1.3 million to the
Company's stockholders in July 1995 and January 1996.

         For fiscal year 1995, the $10.3 million of cash provided by operating
activities was offset by $11.3 million used to repurchase 562,500 shares of the
Company's common stock at an average acquisition price of approximately $20 per
share, $5.7 million of additional investments in and loans to affiliate
companies and the payments of aggregate cash dividends of approximately $1.6
million to the Company's stockholders in July 1994 and January 1995.

         The Company anticipates capital expenditures, equity investments in,
and loans to affiliate companies to be approximately $12.0 million in fiscal
1997. In June 1996, the Board of Directors authorized the Company to repurchase
an additional 500,000 shares of the Company's common stock in the open market
and declared a dividend of ten cents per share for stockholders of record as of
June 14, 1996.

         The Company's principal sources of liquidity include cash generated
from operations, sales of Target stock, and its cash, cash equivalents and
short-term investments. During the fiscal quarter ended September 30, 1994, the
Company's Board of Directors authorized the Company to sell portions of its
holdings of Target's common stock. During fiscal 1995 and 1996, the Company sold
an aggregate of 2,982,500 shares of Target common stock (adjusted for a
two-for-one stock spilt) for an aggregate pre-tax gain of approximately $91.9
million ($105.8 million proceeds less cost basis of $13.9 million). The Company
anticipates that stock sales pursuant to the authorization will be made from
time to time, under SEC Rule 144, with the objective of generating cash, for,
among other things, further investments in both current and new affiliate
companies. In addition, the Company established a $7.0 million revolving credit
facility with a bank in November 1994, which was subsequently increased to $15.0
million in December 1995. As of June 30, 1996, $10.0 million of this credit
facility remained unused. Additionally, the Company has a $3.3 million (4.1
million Swiss Francs) credit facility that was established by LipoMatrix prior
to the Company's acquisition of 

                                    Page 23
<PAGE>   24

LipoMatrix , of which $1.4 million (1.8 million Swiss Francs) remained unused as
of June 30, 1996. The Company believes that these sources should be adequate to
fund its anticipated cash needs through at least the next twelve months.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

         Reliance on Key Products. Sales of the Company's collagen-based
injectable products, Zyderm I Collagen implant and Zyderm II Collagen implant
(collectively, "Zyderm implant") and Zyplast implant, as well as Trilucent
implant accounted for approximately 86% of consolidated product sales for the
fiscal year ended June 30, 1996. The Company's product sales may continue to
consist primarily of sales of these principal products. Factors such as adverse
publicity, adverse rulings by regulatory authorities, product liability
lawsuits, introduction of competitive products by third parties or other loss of
market acceptance for these principal products may significantly and adversely
affect the Company's sales of these products, and as a result, also adversely
affect the Company's business, financial condition and results of operations.

         Dependence on Marketing Partners and Third Party Distributors; Effect
of Inventory Fluctuations. The Company has entered into certain exclusive
arrangements with Bard for the marketing and distribution of the Company's
Contigen implant product and with Zimmer for the marketing and distribution of
the Collagraft bone graft products. As a result, the Company's revenues and
earnings for these products depend substantially upon the continuing efforts of
these marketing partners. The Company's business and financial condition could
be adversely affected in the event that either or both of these parties do not
effectively market the Company's products, accurately anticipate customer demand
or effectively manage industry-wide pricing and cost-containment pressures in
health care. The Company's revenues and earnings fluctuate based upon the levels
of orders placed by these parties, which are in turn affected by the levels of
sales by these distributors and the levels of their inventories. At June 30,
1995, Bard had a significant inventory of Contigen implant and as a result, took
minimal shipments of such product during fiscal 1996. While future shipments to
Bard are expected to resume during fiscal 1997, there can be no assurances that
such actions will occur. The failure to resume shipments of Contigen implant to
Bard during fiscal 1997 and any significant decrease in purchases of Collagraft
bone graft products by Zimmer could have a material adverse effect on the
Company's operating results.

         In addition, the Company depends upon third party distributors to
market its other products in a number of international markets. Difficulties in
the Company's relationship with these distributors and changes in distribution
arrangements may adversely affect the Company's business, financial condition
and results of operations.

         Governmental Regulation and Adverse Publicity. The Company's
manufacturing activities and products sold in the United States are subject to
extensive and rigorous regulation by the FDA and by comparable agencies in
certain foreign countries where these products are manufactured or distributed.
The FDA regulates the manufacture, clinical research and sale of medical
devices, including labeling, advertising and recordkeeping. The Company's
primary products are classified as Class III medical devices, which require
pre-market approval from the FDA. While the Company's other primary products
have been approved for sale in the United States, Trilucent implant is currently
in clinical trials in the United States and, accordingly, has not been approved
for domestic commercial sale. Medical products whose market applications have
not yet been approved by the FDA may only be exported with the specific approval
of the FDA. There can be no assurance that the FDA will choose to characterize
future products as medical devices rather than drugs or biologics. Any such
change in FDA characterization would potentially lengthen and increase the cost
of the approval process. Failure to comply with applicable regulatory
requirements can, among other things, result in fines, suspensions of regulatory
approvals, product recalls, seizure of products, operating restrictions,
injunctions and criminal prosecution. In addition, government regulations may be
established that could prevent or delay regulatory approval of the Company's
products. Furthermore, compliance with current Good Manufacturing Practices
regulations is necessary to receive FDA approval to market new products and to
continue to market current products.

                                    Page 24
<PAGE>   25

         The continuing trend of more stringent FDA oversight in product
clearance and enforcement activities has caused medical device manufacturers to
experience longer approval cycles, more uncertainty, greater risk and higher
expenses. Failure to obtain, or delays in obtaining, the required regulatory
approvals for new products, particularly with respect to Trilucent implant,
could adversely affect the Company as could product recalls. In addition, there
can be no assurance that the FDA will give approval to the Company to market its
current products for broader or different applications, or that it will grant
approval with respect to separate product applications which represent
extensions of the Company's basic technology, or that existing approvals will
not be withdrawn. Further, changes in governmental reimbursement systems,
pursuant to which hospitals and physicians are reimbursed for medical procedures
at a fixed rate according to diagnosis-related groups or other reimbursements,
could have an economic impact on the purchase and use of medical devices. A
material decrease in current reimbursement levels for Contigen Implant and its
application in the treatment of intrinsic sphincter deficiency ("ISD") could
have a material adverse effect on the Company's business, financial condition
and results of operations.

         The collagen used in the Company's products is derived from cow hides.
Bovine Spongiform Encephalopathy ("BSE") is a disease, initially reported in
cattle in the United Kingdom, characterized by degenerative lesions of the
central nervous system. The source of infections in animals derives from eating
infected sheep-derived feed. The disease has been reported in European countries
with less than one percent of cattle being affected. The Company is not aware of
any reports of BSE in United States cattle to date. Furthermore, United States
cattle are not fed sheep-derived protein and the United States prohibits all
importation of British cattle. All of the Company's injectable collagen products
are currently derived from the hides of United States cattle. In response to the
heightened awareness of BSE in Europe, the Company currently uses "closed herds"
that are controlled as to lineage, feed, and separation from other animals.
There can be no assurance that the various foreign or domestic regulatory
authorities will not raise issues regarding BSE or other matters which may
adversely affect the Company's ability to manufacture, market or sell its
products.

         In past years, the Company has been the subject of legislative and
regulatory investigations relating to, among other things, the safety and
efficacy of its injectable collagen products. There can be no assurance that
legislative and regulatory investigations or negative publicity from such
investigations or future investigations or from the news media will not result
in a material adverse effect on the Company's business, financial condition or
results of operations. In addition, significant negative publicity could result
in an increased number of product liability claims.

         Risk of Investments in Affiliates. The Company has made significant
equity and debt investments in affiliated companies that are involved in the
development of complementary or related technologies or products, and the
Company currently intends to continue to make significant additional investments
from time to time in the future. These affiliated companies typically are in an
early stage of development and may be expected to incur substantial losses. As a
result, the Company has recorded and expects to continue to record a share of
the losses in such affiliates attributable to the Company's ownership, which
losses have had and will continue to have an adverse effect on the Company's
operating results. Furthermore, there can be no assurance that any investments
in affiliates will result in any return nor as to the timing of such return, or
that the Company will not lose its entire investment.

         Effect of Ownership Interest in Target. As of June 30, 1996, the
Company owned approximately 1.6 million shares of Target Common Stock,
representing approximately 11% of the outstanding shares of Target Common Stock
valued at over $65 million (based on a market price of $41 per share on such
date). The Company's earnings have been significantly favorably affected in
recent periods by revenues resulting from the sale of portions of the Company's
holdings in Target. The Company has engaged in regular open-market sales of its
Target Common Stock and expects to continue such sales. The Company's ownership
of Target may also be further reduced through additional equity offerings by
Target that dilute the Company's ownership interest. The market price of
Target's Common Stock is highly volatile and, as a medical device manufacture,
Target is subject to a number of the same factors affecting its operations as
the Company, as well as additional factors not applicable to the Company.
Readers are encouraged to review Target's public filings for a 

                                    Page 25
<PAGE>   26

detailed understanding of the nature of Target's business and the risk and
uncertainties associated with it. Any significant downward fluctuation in the
market price for Target Common Stock could adversely impact the Company's
earnings (due to lower returns per share on sales of such stock) as well as the
value of the Company's total assets as stated on its balance sheet (based on a
lower carrying value for the Target investment, which as of June 30, 1996,
represented approximately 40% of the value of the Company's total assets).

         Competition. The medical device industry is characterized by rapidly
evolving technology and increasing competition. At the present time there is a
commercial product in the United States that is directly competitive with Zyderm
and Zyplast implants, the Company's collagen-based products for cosmetic and
reconstructive surgery. This product is a gelatin-based (denatured collagen)
product for soft tissue augmentation presently being marketed in the United
States and Canada. The Company is also aware of one foreign company which is
marketing internationally a the collagen-based material for soft tissue
augmentation. In addition, several companies are engaged in research and
development activities relating to the use of collagen and other biomaterials
for the correction of soft tissue defects. The Company's injectable collagen
products also compete in the dermatology and plastic surgery markets with
substantially different alternative treatments, such as surgery and topical
applications. In addition, several companies and institutions are engaged in the
development of collagen-based and other materials, techniques, procedures and
products for use in medical applications anticipated to be addressed by the
Company's Contigen implant and Collagraft bone graft products. Furthermore,
several companies market mammary implants that do or will compete with the
Trilucent implant. Some of these companies and institutions may, and with
respect to certain of the companies marketing products competitively Trilucent
implant certainly do, have substantially greater capital resources; research and
development staffs and facilities; and experience in conducting clinical trials,
obtaining regulatory approvals, and manufacturing and marketing products similar
to those of the Company. These companies and institutions may represent
significant long-term competition for the Company. There can be no assurance
that the Company's competitors will not succeed in developing technologies and
products that are more effective than any which have been or may be developed by
the Company or that would render the Company's technology and products obsolete
or non-competitive. There can be no assurance that such potential competition
will not have an adverse effect on the future business, financial condition or
results of operations of the Company. Certain of the Company's collagen-based
products, including the Zyderm implants, were manufactured and sold pursuant to
an exclusive license from Stanford University under a United States patent,
which expired in April 1993, covering the use of native, solubilized collagen
for soft-tissue augmentation. The expiration of this patent may result in
increased competition in the market for injectable collagen implants if and as
other companies enter that market.

         Undeveloped and Uncertain Markets. Certain of the Company's products,
including those marketed by its marketing partners, are intended for use in new
markets the size of which are difficult to independently verify. In particular,
the potential market for the Company's Contigen product is difficult to estimate
because Contigen implant represents a relatively new method of treatment, and
the Company believes that most sufferers of stress urinary incontinence do not
seek medical treatment. Furthermore, Contigen implant is marketed to urologists,
whom the Company believes generally are not the primary care physician for
individuals seeking treatment for this disorder. Should the markets for such
products be more limited than the Company or its marketing partners currently
estimate, or should the Company, its distributors and/or its marketing partners
fail to penetrate such markets to the extent anticipated, the Company may
experience lower than anticipated revenues and a resulting adverse effect on its
business, financial condition and results of operations.

         Patents and Proprietary Technology. The Company depends substantially
upon its proprietary technological expertise in the extraction, purification,
and formulation of collagen-based materials and other biomaterials into
biomedical products. The Company seeks patents on inventions concerning novel
manufacturing processes, compositions of matter, and applications for its
proprietary biomaterials.

                                    Page 26
<PAGE>   27

         Patent-related litigation is an increasing risk in the medical device
industry. There can be no assurance the Company will be successful in the future
in obtaining patents or license rights, that patents will be issued for the
Company's current patent applications, that the Company will develop additional
proprietary technology that is patentable, that any issued patents will provide
the Company with any competitive advantages or will not be challenged by third
parties, or that patents of others will not have an adverse effect on the
Company. There can be no assurance that others will not independently develop
similar products, duplicate any of the Company's products, or design around any
patents used by the Company. No assurance can be given that the Company's
processes or products will not infringe patents or proprietary rights of others
or that any licenses required under any such patents or proprietary rights would
be made available on terms acceptable to the Company. If the Company does not
obtain such licenses, it could encounter delays in product introductions while
it attempts to design around such patents, or it could find that the
manufacture, sale or use of products requiring such licenses could be enjoined.
In addition, the Company could incur substantial costs in defending itself in
suits brought against the Company on such patents or in bringing suits to
protect the Company's patents against infringement.

         Product Liability; Insurance. The Company is involved in various legal
actions arising in the ordinary course of business, the majority of which
involve product liability claims. While the outcome of such matters currently is
not determinable it is management's opinion that these matters will not have a
material adverse effect on the Company's future consolidated financial position
and results of operations.

         The Company faces an inherent business risk of exposure to product
liability claims alleging that the use of the Company's technology or products
has resulted in adverse effects, particularly with respect to claims regarding
Trilucent implant, which is sold in a medical field (breast reconstruction and
augmentation) in which there have been sizable product liability claims. Such
risks will exist even with respect to those products that have received or in
the future may receive regulatory approval for commercial sale. There can be no
assurance that the Company will avoid significant product liability claims and
attendant negative publicity. Furthermore, there can be no assurance that
present insurance coverage will be adequate or that adequate insurance coverage
will remain available at acceptable costs, if at all, or that a product
liability claim or recall would not adversely affect the future business or
financial condition of the Company. A successful claim brought against the
Company for which coverage is denied or in excess of its insurance coverage
could have a material adverse effect on the Company's business, financial
condition and results of operations. In addition, adverse product liability
actions could negatively affect the Company's ability to obtain and maintain
regulatory approval for its products.

         In light of regulatory investigations surrounding product safety, the
Company announced in September 1991 that it would indemnify physicians against
damages and legal fees arising from lawsuits brought to a jury trial alleging a
link between the Company injections and Polymyositis and Dermatomyositis. To
date, there has not been any impact of this indemnification on the Company's
results of operations. There can be no assurance, however, that any future such
claims would not have a material adverse effect on the Company's operating
results. Because the indemnification program has never been utilized, the
Company may discontinue the program in the future.

         Impact of Currency Fluctuations; Importance of Foreign Sales.
Approximately 44% of the Company's revenues in fiscal year 1996 came from its
international operations. Because international sales of the Company's products
typically are denominated in local currencies, the Company's results of
operations have been and are expected to continue to be affected by changes in
exchange rates between certain foreign currencies and the United States dollar.
Although the effect of currency fluctuations on the Company's operating results
were positive during fiscal 1996, there can be no assurance that the Company
will not experience unfavorable currency fluctuation effects in future periods,
which could have an adverse effect on the Company's operating results. Company's
operations and financial results also may be significantly affected by other
international factors, including changes in governmental regulations or import
and export restrictions, and foreign economic and political conditions
generally.

         Limited Diversity of Facilities. All of the Company's manufacturing
capacity for collagen products, the majority of its research and development
activities, its corporate headquarters, and other critical business functions
are located near major earthquake faults. In addition, all of the Company's
manufacturing capacity for collagen-based products and Trilucent implant are
located in two primary facilities (one for collagen-based products and one for
Trilucent implant), with the Company currently maintaining only limited amounts
of finished product inventory. While the Company has some limited protection in
the form of disaster recovery programs and basic insurance coverage, the
Company's operating results and financial condition would be materially
adversely affected in the event of a major earthquake, fire or other similar
calamity, affecting its manufacturing facilities.

         Dependence on Key Personnel. The Company is dependent upon a limited
number of key management and technical personnel, the loss of any one of which
could have a material adverse effect on the Company's business. The Company's
future success will depend in part upon its ability to attract and retain highly
qualified personnel. The Company competes for such personnel with other
companies, academic institutions, government entities and other organizations.
There can be no assurance that the Company will be successful in hiring or
retaining qualified personnel.

         Third-Party Reimbursement. Certain of the Company's products, including
Contigen implant, the Collagraft bone graft products, and, in certain
circumstances, Trilucent implant are purchased by hospitals or physicians,
which, in the United States, then bill various third-party payors including
Medicare, Medicaid and private insurers for the healthcare services provided to
patients. Third-party payors are increasingly challenging the prices charged for
medical products and services. There can be no assurance that the reimbursement
of treatments using the Company's products will not be subject to such
challenges in the future.

         The foregoing factors are not meant to represent an exhaustive list of
the risks and uncertainties attendant to the Company's business. Due to the
factors noted above, as well as other factors that may affect the Company's
operating results, the Company's future earnings and stock price may be subject
to significant volatility, particularly on a quarterly basis. Any shortfall in
revenue or earnings from levels expected by securities analysts could have an
immediate and significant adverse effect on the trading price of the Company's
common stock in any given period. Additionally, the Company may not learn of, or
be able to confirm, such shortfalls until late in the fiscal quarter, or
following the end of the quarter, which could result in an even more immediate
and adverse effect on the trading price of the Company's common stock. Finally,
the Company participates in a highly dynamic industry, which often results in
significant volatility of the Company's common stock.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of Collagen
Corporation (the "Company"), a Delaware corporation, and its wholly-owned and
majority-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated. The Company operates in one industry segment
focusing on the development, manufacturing and sale of medical devices.
Investments in unconsolidated subsidiaries, and other investments in which the
Company has a 20% to 50% interest or otherwise has the ability to exercise
significant influence, are accounted for under the equity method.

         Investments in companies in which the Company has less than a 20%
interest are carried at cost or estimated realizable value, if less. In fiscal
1996 and 1995, investments were written down by $4.0 million and $925,000,
respectively, to estimated net realizable value. (See Notes 4, 5 and 6).

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

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

RECLASSIFICATION

         Certain prior year amounts in the consolidated financial statements
have been reclassified to conform with the current year presentation.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

         The Company considers all highly liquid investments with a maturity
from date of purchase of three months or less to be cash equivalents. Short-term
investments consist principally of bankers acceptances, commercial paper and
master notes and have maturities greater than 90 days, but not exceeding one
year.

         The Company invests its excess cash in deposits with major banks and in
money market securities of companies with strong credit ratings and from a
variety of industries. These securities are typically short-term in nature and,
therefore, bear minimal risk. The Company has not experienced any losses on its
money market investments.

         The Company determines the appropriate classification of marketable
securities at the time of purchase and re-evaluates such designation as of each
balance sheet date. All of the Company's debt and equity securities are
classified as available-for-sale. The carrying value of available-for-sale debt
securities approximates fair value because of the short-term maturity of these
investments. Both realized and unrealized gains and losses on debt securities
were immaterial at June 30, 1996 and 1995. Available-for-sale equity securities,
which includes holdings in Target Therapeutics, Inc., are carried at fair value
with the unrealized gains and losses, net of tax, reported as a separate
component of stockholders' equity. The amortized cost of debt securities in this
category is adjusted for amortization of premiums and accretion of discounts to
maturity. Such amortization is included in interest income. Realized gains and
losses and declines in value judged to be other-than-temporary on
available-for-sale debt securities are included in interest income. The cost of
securities sold is based on the specific identification method. Interest and
dividends on securities classified as available-for-sale are included in
interest income.

INVENTORIES

         Inventories are valued at the lower of cost, determined on a standard
cost basis which approximates average cost, or market.

PROPERTY AND EQUIPMENT

         Depreciation and amortization of property and equipment which is stated
at cost are provided on the straight-line method over estimated useful lives as
follows:

<TABLE>
<S>                                                                <C>     
                           Machinery and equipment                  5 - 10 years
                           Leasehold improvements                  Term of lease
</TABLE>

INTANGIBLE ASSETS

         Intangible assets are amortized using the straight-line method. Patents
are amortized over a seventeen-year period beginning with the effective date or
over the remainder of such period from the date acquired. Trademarks are
amortized over a twenty-year period beginning with the trademark filing dates.
Purchased product distribution rights are amortized over their estimated useful
lives (generally five years).

PURCHASED INTANGIBLES AND GOODWILL

         The excess cost over the fair value of net assets acquired (goodwill)
is generally amortized on a straight-line basis over a period not exceeding
seven years. The cost of identified intangibles is generally amortized on a
straight-line basis over a period of seven years. The carrying value of goodwill
and intangible assets is reviewed on a regular basis for the existence of facts
or circumstances both internally and externally that may suggest impairment.

         In 1995, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No.121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS #121").
Adoption of SFAS#121 in fiscal 1997 is not expected to have a material impact on
the Company's financial position or results of operations.

LOANS TO OFFICERS AND EMPLOYEES

         Principal plus accrued interest due from current and former employees
totaled approximately $378,000 and $267,000 at June 30, 1996 and 1995,
respectively, and principal plus accrued interest due from officers totaled
approximately $1,646,000 and $492,000 at June 30, 1996 and 1995, respectively.

         Included within the amounts due from officers at June 30, 1996 is
$450,000 of promissory notes secured by shares of the Company's stock and
repayable five years from the date of issuance and an unsecured promissory note
of $1,080,000, due from the Company's Chairman and Chief Executive Officer. The
$1,080,000 note is repayable at any time and payable immediately upon the
termination of his employment with the Company. All such notes are subject to
interest at the lower of 10% per annum or the prime rate.

REVENUE RECOGNITION

         Revenue from product sales is recognized at time of shipment, net of
allowances for estimated future returns.

CONCENTRATION OF CREDIT RISK

         The Company sells its plastic surgery and dermatological products
primarily to physicians and pharmacies in North America, Europe and the Pacific
Rim. The Company sells Contigen(R) Bard collagen implant ("Contigen implant") to
C.R. Bard, Inc. ("Bard"), its marketing partner for Contigen implant, and
Collagraft(R) bone graft matrix implant and Collagraft(R) bone graft matrix
strip to Zimmer, Inc., the Company's marketing partner for Collagraft(R) bone
graft products. The Company performs ongoing credit evaluations of its customers
and generally does not require 

                                    Page 35
<PAGE>   36

collateral. The Company maintains reserves for potential credit losses and such
losses have been within management's expectations.

         The Company allows, on occasion, its customers to return product for
credit, and also allows customers to return defective or damaged product for
credit or replacement. Written authorization from the Company is required to
return merchandise. Some domestic and foreign customers are subject to extended
payment terms. These practices have not had a material effect on the Company's
working capital.

ADVERTISING COSTS

         The Company expenses advertising costs as incurred. Total advertising
expense was $1,036,000 and $840,000 for 1996 and 1995, respectively, and was not
material for fiscal 1994.

EARNINGS PER SHARE

         Earnings per share have been computed based upon the weighted average
number of common and dilutive common equivalent shares outstanding. Common
equivalent shares result from stock options.

FOREIGN CURRENCY TRANSLATION

         The functional currency for each foreign subsidiary is its respective
foreign currency. Accordingly, all assets and liabilities related to these
operations are translated at the current exchange rates at the end of each
period. The resulting cumulative translation adjustments are recorded directly
to the accumulated foreign currency translation adjustment account included in
stockholders' equity. Revenues and expenses are translated at average exchange
rates in effect during the period. Foreign currency transaction gains and losses
are included in results of operations.

         Until December 1994, the Company's policy was to hedge material foreign
currency transaction exposures. At June 30, 1996 and June 30, 1995, no foreign
currency transaction exposures were hedged. Unhedged net foreign assets were
$14.5 million and $10.4 million at June 30, 1996 and June 30, 1995,
respectively.

         During the years ended June 30, 1996 and 1995, the Company sold
available-for-sale investments with a fair value at the dates of sale of $4.0
million and $7.3 million, respectively. Both gross realized and unrealized gains
and losses on these securities were insignificant. The Company uses amortized
cost as the basis for recording gains and losses from securities transactions.
Contractual maturities of the debt securities do not exceed one year at June 30,
1996.

4.   INVESTMENT IN TARGET THERAPEUTICS, INC. ("TARGET")

         The Company's investment in Target was accounted for under the equity
method through November 1995. During December 1995, the Company's interest in
Target fell below 20%. Given that the Company does not have the ability to
exercise significant influence, the Company began accounting for its investment
in Target under the cost method beginning in December 1995. In fiscal 1996, the
Company sold 1,792,000 shares of Target common stock for a pre-tax gain of
approximately $85.8 million and in fiscal 1995, the Company sold 245,000 shares
of Target common stock for a pre-tax gain of approximately $6.0 million. The
Company's ownership position in Target as of June 30, 1996 was approximately
11%.

         Target's common stock is quoted on The Nasdaq Stock Market. The closing
price of Target's stock at June 30, 1996 was $41 per share. The Company held
1,605,888 shares of Target's common stock at June 30, 1996.

         At June 30, 1996, the Company's shares of Target common stock are
classified as available-for-sale and have been recorded at the estimated fair
value of $65.8 million. The $58.4 million unrealized gain ($65.8 million
estimated fair value less $7.4 million cost) on these available-for-sale
securities has been reported as a separate component of stockholders' equity,
net of tax. As of August 2, 1996, Target's closing stock price was $33 ae per
share, resulting in a decrease of $11.6 million in the estimated fair value of
the Company's holdings in Target Therapeutics, Inc.

5.   INVESTMENT IN INNOVASIVE DEVICES, INC.

         In October 1995, the Company purchased approximately 844,000 shares of
common stock or approximately 12% in Innovasive Devices, Inc. (of Hopkington,
Massachusetts) and entered into a collaborative product development agreement
with Innovasive Devices, Inc. ("Innovasive Devices"). The Company and Innovasive
Devices are collaborating to develop certain resorbable or partially resorbable
mechanical tissue-fixation devices utilizing collagen-based biomaterials for
applications in orthopedic tissue repairs. Innovasive Devices is a company that
develops, manufactures, and markets tissue and bone reattachment systems which
are particularly relevant to the sports medicine.

         Innovasive Devices completed a public offering of its securities in
June 1996. At June 30, 1996, Innovasive Devices' closing price on the Nasdaq
Stock Market was $10 per share. Due to restrictions which prevent the sale of
any of the Company's shares of Innovasive Devices until October 1997, this
investment is valued at cost of $4,064,000 at June 30, 1996.

6.   AQUISITIONS

LipoMatrix

         LipoMatrix, Incorporated ("LipoMatrix") is the developer and
manufacturer of the Trilucent(TM) breast implant, which is the first
commercially available triglyceride-filled mammary implant in the world. In
fiscal 1996, the Company introduced the Trilucent implant in most countries of
Western Europe.

         On August 22, 1995, as part of the Company's strategy to expand in its
marketing franchise in aesthetic and reconstructive products, the Company
entered into a stock purchase agreement ("Agreement") with certain of the
stockholders of LipoMatrix to purchase approximately 50% of its outstanding
securities on a fully diluted basis. The Company also entered into a stock
purchase agreement with certain of LipoMatrix's management and employees to
purchase the remaining 10% of the outstanding securities of LipoMatrix on a
fully diluted basis. This purchase increased the Company's ownership interest in
LipoMatrix from approximately 40% to 100% of the outstanding securities on a
fully diluted basis.

         The acquisition of LipoMatrix, which was accounted for as a purchase,
had an aggregate purchase price of approximately $23.7 million, consisting of
payments to LipoMatrix shareholders, the balance of the Company's investment in
LipoMatrix at the date of purchase, direct costs and the assumption of
LipoMatrix' net liabilities of $926,000. The Company completed the closing of
the aforementioned acquisition of LipoMatrix in January 1996 at which time
aggregate cash payments of approximately $20.1 million were made by the Company
to the selling LipoMatrix stockholders, as well as certain of LipoMatrix's
current and former employees.

         The assets and liabilities assumed by the Company were recorded based
on their independently appraised fair values at the date of the acquisition. Of
the purchase price of $23.7 million, $14.8 million was allocated to in-process
research and development, $3.8 million to intangible assets and $5.1 million to
goodwill. The amount allocated to in-process research and development was
expensed at the time of the acquisition. The Company's results of operations for
fiscal 1996, include LipoMatrix' results from August 22, 1995, through June 30,
1996.

         The unaudited pro forma results of operations of the Company for fiscal
years 1996 and 1995, respectively, assuming the acquisition of LipoMatrix
occurred on July 1, 1993, on the basis described above with all material
intercompany transactions eliminated, are as follows:

Cohesion Corporation

         The Company increased its ownership position in Cohesion Corporation
(of Palo Alto, California) from 40% to approximately 81% on May 29, 1996.
Cohesion Corporation is a privately-held company that is developing novel
biomaterials with superior performance characteristics in the areas of tissue
adhesives, hemostats, biosealants, and adhesion prevention. In connection with
the Company's investment in Cohesion Corporation, $3.0 million was allocated to
in-process research and development, which was expensed at the time of the
investment and $2.5 million was allocated to tangible assets. Cohesion
Corporation anticipates that its lead product will begin clinical evaluation in
the third or fourth quarter of fiscal 1997.

         The Company determined the amounts to be allocated to in-process
technology for Cohesion Corporation based on whether technological feasibility
had been achieved and whether there was any alternative future use for the
technology. The Company concluded that the in-process technology had no
alternative future use after taking into consideration the potential for both
usage of the technology in different products and for resale of the technology.

         Proforma information related to the purchase acquisition of Cohesion
Corporation has not been presented as the results of operations of Cohesion are
not material to the Company's operating results.

REVOLVING LINE OF CREDIT AGREEMENT

         In November 1994, the Company entered into a $7 million revolving line
of credit with a bank, secured by shares of Target common stock held by the
Company. The terms of this facility contain certain financial covenants and
restricts the aggregate amount of cash dividends. In December 1995, the $7
million revolving line of credit was increased to $15 million. During fiscal
1996, $5 million was borrowed under this agreement leaving $10 million of this
credit facility unused as of June 30, 1996, and no amounts were borrowed under
this agreement as of June 30, 1995. Interest associated with this agreement is
at the Company's option, based on either the prime rate plus 1/2% or the
Eurodollar rate plus the lesser of 1 1/4% or the Alternate LIBOR applicable
margin. Interest is payable monthly. Additionally, the Company is required to
pay, on a quarterly basis, a commitment fee of 3/8 of 1% per annum of the unused
portion. This credit facility expires on November 15, 1997.

TERM LOANS AND LINE OF CREDIT

         Prior to the Company's acquisition of LipoMatrix, LipoMatrix
established three term loans and a general credit line with a major bank,
totaling $3.3 million (4.1 Swiss Francs). As of June 30, 1996, $1.4 million (1.8
million Swiss Francs) of these credit facilities is unused. Borrowings under
these credit facilities bear interest at 7% per annum, payable semi-annually in
June and December. Interest subsidies totaling 5.075% are received on the term
loans annually, resulting in a net interest rate due on the term loans of
1.925%. Semi-annual repayment of these credit facilities began on June 30, 1996,
and continues over a period not to exceed ten years. Approximately one-half of
these credit facilities is guaranteed by the Swiss Confederation.

BONUS AGREEMENT

         In February 1996, the Company entered into a cash bonus agreement with
the Company's Chairman and Chief Executive Officer whereby cash bonuses in the
amounts of $325,000, $305,000, $285,000, $265,000 and $245,000 will be paid to
him on February 13 of each of the next five years beginning in 1997, providing
that he continue to serve the Company on the applicable payment date.

8.     LEGAL MATTERS

         The Company is involved in legal actions, including product liability
and intellectual property claims, arising in the ordinary course of business.
While the outcome of such matters is currently not determinable, it is
management's opinion that these matters will not have a material adverse effect
on the Company's consolidated financial position or results of its operations.

9.    STOCKHOLDERS' EQUITY

STOCK OPTIONS

         The Company has various stock option plans under which incentive stock
options or non-statutory stock options may be granted to officers, directors,
key employees and consultants to purchase the Company's common stock. The
options are granted at no less than the fair market value at the dates of grant
and generally expire after ten years. Incentive stock options become exercisable
at the rate of two percent each month beginning the first full month after the
date of grant unless accelerated by the Board of Directors. Non-statutory stock
options become exercisable on a monthly or yearly basis as determined by the
Board of Directors at the date of grant.

employees. Subsequently, the Company increased the authorization to 600,000
shares. Under the plan, the Company's employees, subject to certain
restrictions, may purchase shares at a price per share that is the lesser of 85
percent of the fair market value as of the beginning or close of the yearly
offering period.

         For fiscal 1996, 1995 and 1994, shares issued under the plan were
34,084, 36,100, and 32,741, respectively. The average issuance price per share
was $17.83, $19.28 and $19.00 for fiscal 1996, 1995 and 1994, respectively. At
June 30, 1996, 67,909 shares remained available for future sales under this
plan.

STOCK REPURCHASE PROGRAM

         In February 1993, the Company's Board of Directors authorized a stock
repurchase program. In fiscal 1996, 1995 and 1994, the Company repurchased
300,000, 562,500 and 567,500 shares at average acquisition prices of
approximately $18, $20 and $24 per share, respectively. In June 1996, the Board
of Directors authorized the repurchase of up to an additional 500,000 shares.
The Company plans to retain repurchased shares as treasury stock, but may use a
portion of the stock in various company stock benefit plans.

STOCKHOLDER RIGHTS PLAN

         In November 1994, the Board of Directors approved a stockholder rights
plan which would entitle stockholders to purchase stock in the Company or in an
acquirer of the Company at a discounted price in the event of certain hostile
efforts to acquire control of the Company. The rights may only be exercised, if
at all, upon the occurrence of certain events unless earlier redeemed pursuant
to the plan. The rights expire on November 28, 2004.

10.    INTERNATIONAL SALES AND DISTRIBUTION RIGHTS

         Export sales were $32.6 million in fiscal 1996, $26.1 million in fiscal
1995 and $20.8 million in fiscal 1994. These export sales are primarily in
Europe, Canada and the Pacific Rim. The Company markets its products
internationally directly in Canada, ten European countries, Australia and New
Zealand and via distributors in other countries. During fiscal 1996, the Company
paid commissions based upon a percentage of net sales to its former European
distributor, whose contract expired in December 1995.

11.    MAJOR CUSTOMER AND PRODUCTS

         During fiscal 1996, 1995 and 1994, the Company realized product sales
from its marketing partner, Bard of $6.2 million, $16.5 million and $16.7
million, respectively, which represented 9%, 23% and 26% of product sales. Bard
has exclusive worldwide marketing and distribution rights for Contigen implant,
a product introduced in fiscal 1994. These amounts were comprised of product
sales of $.3 million, $13.4 million and $15.9 million of Contigen implant as
well as $5.9 million, $3.1 million and $0.8 million of income from Bard's direct
sales of Contigen implant to physicians in fiscal 1996, 1995 and 1994,
respectively. In fiscal years 1996, 1995 and 1994, the Company also recorded
other revenue of $2.0 million, $1 million and $1 million, respectively, which
consisted of milestone payments from Bard in accordance with an agreement
between the Company and Bard. The final milestone payment of $2.0 million was
paid to the Company on September 30, 1995. In fiscal 1996 and 1995, 82% and 72%
of sales were derived from Zyderm/Zyplast products.

         All of the Company's manufacturing capacity for collagen products, the
majority of its research and development activities, its corporate headquarters,
and other critical business functions are located near major earthquake faults.
In addition, all of the manufacturing capacity for collagen-based products and
Trilucent implant are located in two primary facilities (one for collagen-based
products and one for Trilucent implant) with the Company currently maintaining
only limited amounts of finished product inventory. While the Company has some
limited protection in the form of disaster recovery programs and basic insurance
coverage, the Company's operating results and financial condition would be
materially adversely affected in the event of a major earthquake, fire or other
similar calamity, affecting its manufacturing facilities.

12.    INCOME  TAXES

         The Company uses the liability method of accounting for income taxes
required by SFAS No. 109.

         Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax assets and liabilities as of June 30,
1996 and June 30, 1995 are presented below:

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders,
Collagen Corporation

We have audited the accompanying consolidated balance sheets of Collagen
Corporation as of June 30, 1996 and 1995, and the related consolidated
statements of income, stockholders' equity and cash flows for each of the three
years in the period ended June 30, 1996. Our audits also included the financial
statement schedule listed in the Index at Item 14(a). These financial statements
and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Collagen
Corporation at June 30, 1996 and 1995, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1996 in conformity with generally accepted accounting principles. Also,
in our opinion, the related financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly in
all material respects, the information set forth therein.

                        SUPPLEMENT TO SECURITY AGREEMENT


                  SUPPLEMENT, dated as of June 28, 1996, made by COHESION
CORPORATION, a California corporation (the "New Grantor") to the Security
Agreement, dated as of November 15, 1994 (the "Security Agreement"), by and
among Collagen Corporation, a Delaware corporation (the "Borrower"), each
Guarantor party thereto and THE BANK OF NEW YORK (the "Lender").

                  A. Reference is made to the Credit Agreement, dated as of
November 15, 1994, (as amended, modified or supplemented from time to time, the
"Credit Agreement"), between the Borrower and the Lender.

                  B. Capitalized terms used herein and not otherwise defined
herein shall have the meanings assigned to such terms in the Security Agreement
or the Credit Agreement, as the case may be.

                  C. The Grantors have entered into the Security Agreement in
order to induce the Lender to enter into the Credit Agreement and make the Other
Loans. Pursuant to the Credit Agreement, the Lender may require certain
Subsidiaries of the Borrower to be added under the Credit Agreement as
Designated Subsidiaries, in which event said Subsidiary shall be required to
enter into the Guaranty as an additional Guarantor. Section 22 of the Security
Agreement provides that such Subsidiaries of the Borrower may become Grantors
under the Security Agreement by the execution and delivery of an instrument in
the form of this Supplement. The New Grantor is a Subsidiary of the Borrower and
is executing this Supplement in accordance with the requirements of the Credit
Agreement to become a Grantor under the Security Agreement in order to induce
the Lender to make additional Other Loans and as consideration for Loans
previously made.

                  Accordingly, the Lender and the New Grantor agree as follows:

                  1. In accordance with Section 22 of the Security Agreement, by
signing this Supplement, the New Grantor (a) shall be, and shall be deemed to
be, a "Grantor" under, and as such term is defined in, the Security Agreement
with the same force and effect as if originally named therein as a Grantor, (b)
shall have made, and shall be deemed to have made, the representations and
warranties contained in Section 6 of the Security Agreement on and as of the
date hereof, and (c) shall have made, and shall be deemed to have made, all of
the covenants and agreements of a Grantor set forth in the Security Agreement.
<PAGE>   8
                  2. The New Grantor represents and warrants to the Lender that
this Supplement has been duly authorized, executed and delivered by it and
constitutes its legal, valid and binding obligations, enforceable against it in
accordance with its terms, except as the enforceability thereof may be limited
by bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or
other similar laws affecting creditors' rights generally and by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or an action at law).

                  3. Except as expressly supplemented hereby, the Security
Agreement shall remain in full force and effect.

                  4. This Supplement shall be governed by and construed in
accordance with the laws of the State of New York without regard to conflicts of
laws rules.

                  5. Every provision of this Supplement is intended to be
severable, and if any term or provision hereof shall be invalid, illegal or
unenforceable for any reason, the validity, legality and enforceability of the
remaining provisions hereof or thereof shall not be affected or impaired
thereby, and any invalidity, illegality or unenforceability in any jurisdiction
shall not affect the validity, legality or enforceability of any such term or
provision in any other jurisdiction.

                  6. For purposes of Section 19 of the Security Agreement, the
address of the New Grantor is as follows:

                           COHESION CORPORATION
                           2500 Faber Place
                           Palo Alto, CA 94303

                           Telephone No.:  (415) 856-0200
                           Attention: Chief Financial Officer

                  7. The New Grantor agrees to reimburse the Lender for its
reasonable out-of-pocket expenses in connection with this Supplement, including
the reasonable fees, other charges and disbursements of counsel to the Lender.

                  8. This Supplement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute but one instrument. This Supplement shall
become effective when the Lender shall have received counterparts of this
Supplement that, when taken together, bear the signatures of the New Grantor and
the Lender.

                  The New Grantor and the Lender have duly executed this
Supplement to the Security Agreement as of the day and year first above written.

         WHEREAS, Collagen and Dr. Perkins desire to provide for the sale and
transfer of 25,000 shares of the Company's Common Stock from Dr. Perkins to
Collagen for each $1,000,000 advanced to the Company by Collagen pursuant to
this Agreement.

         NOW, THEREFORE, the parties hereby agree as follows:

SECTION 1.        LOAN AND NOTES

         1.1 Loan. Collagen agrees, on the terms of and subject to the
conditions specified in this Agreement, to lend to the Company, from time to
time and at the request of the President of the Company, up to an aggregate of
$5,000,000 (the "Loan Amount"). Each loan shall be evidenced by a promissory
note (the "Note") dated as of the date of the loan and in the form of Exhibit A
(each a "Note" and collectively the "Notes").

         1.2 Installments.

         (a) The Company shall be entitled to borrow funds from Collagen in
installments until such time as the Company shall have borrowed the entire Loan
Amount, subject to the following:

Collagen's receipt of the Loan Request;

                  (ii) Loan Requests may be made (A) at any time after the

Company's Common Stock;

                  (iii) The minimum amount that may be loaned to the Company at

conversion of the Note for investment and not with a view towards distribution

Collagen understands that the Notes, and any securities issued upon conversion
thereof will be legended in form satisfactory to the Company's counsel
restricting transfer except in compliance with securities laws. Collagen

the Company, and has had access to all information which it has requested
concerning the Company.

SECTION 3.        DEFAULT.

Agreement; and

                  (b) The filing of a petition in bankruptcy or under any
similar insolvency law by Company, the making of an assignment for the benefit
of creditors, or if any voluntary petition in bankruptcy or under any similar
insolvency law is filed against Company and such petition is not dismissed

Upon each such default pursuant to Section 3(a) above, the Company shall have
forty-five (45) days to cure such default after receipt of written notice of
default from Collagen specifying the nature of the Company's default. If the
Company is unable to cure its default within forty-five (45) days, Collagen may,
at its option, accelerate repayment of Outstanding Balance, in which case the
Outstanding Balance, and all interest accrued thereon shall be due and payable
on the ninetieth (90th) day following the date of Collagen's written notice of
default.

SECTION 4.        CONVERSION

         4.1 Conversion Upon a Public Offering. In the event of a closing of the
Company's sale of its Common Stock in a firm commitment underwriting pursuant to
a registration statement under the Securities Act of 1933, as amended (a "Public
Offering"), then upon the closing of the Public Offering all of the outstanding
unpaid principal balance and accrued interest under the Notes shall be converted
into fully paid and nonassessable shares of Common Stock of the Company, at the
price per share at which such Common Stock is sold to the public (prior to
deduction for underwriting discounts and expenses).

         4.2 Conversion Upon a Merger. In the event of (i) a merger or
consolidation of the Company with or into any other corporation pursuant to
which the shareholders of the Company hold less than fifty percent (50%) of the
voting securities of the surviving corporation or (ii) a sale of all or
substantially all of the assets of the Company (each an "Acquisition"), then
immediately prior and subject to the closing of the Acquisition all of the
outstanding unpaid principal balance and accrued interest under the Notes shall
be converted into fully paid and nonassessable shares of Common Stock of the
Company at a price per share equal to the consideration per share to be received
in the Acquisition by the holders of the Company's Common Stock. In the event
such consideration includes securities or other non-cash


                                      -3-
<PAGE>   4
consideration to be paid to shareholders of the Company, such consideration
shall be valued for purposes of conversion under this Section 4.2 using the
method used to value the consideration paid to other shareholders of the Company
in the Acquisition.

         4.3 Notice. In the event of a Public Offering or Acquisition, the
Company shall give Collagen not less than twenty (20) days prior written notice
of the proposed closing date of such transaction.
 

         4.4 Issuance of Securities on Conversion. As soon as practicable after
conversion of the Notes, the Company at its expense will cause to be issued in
the name of and delivered to Collagen a certificate or certificates for the
number of fully paid and nonassessable shares of capital stock of the Company to
which Collagen shall be entitled on such conversion, together with any other
securities and property to which Collagen is entitled on conversion under the
terms of this Agreement. No fractional shares will be issued on conversion of
the Note. If on conversion of the Note a fraction of a share results, the
Company will pay the cash value of that fractional share, calculated on the
basis of the applicable conversion price.

SECTION 5.        CONSIDERATION FOR LOAN; TERMINATION OF LOAN

         5.1 Termination. If the Company raises funds through the sale of equity
securities to a party other than Collagen after the date of this Agreement and
before a total of $5,000,000 has been loaned hereunder (a "Financing") and
Collagen is given notice of and the opportunity to participate in the Financing
pursuant to Section 2.1 of the Amended and Restated Rights Agreement of even
date herewith, then

                  (a) if Collagen elects not to participate in the Financing or
elects to participate as to an amount less than the remaining undrawn portion of
the Loan Amount, the Loan Amount shall be thereafter reduced by an amount equal
to the amount of equity funds raised in the Financing from parties other than
Collagen; provided that in no case shall the Loan Amount be reduced below the
actual loans previously advanced to the Company hereunder; and

                  (b) if Collagen elects to participate in the Financing, the
amount invested by Collagen in the Financing will be credited towards Collagen's
$5,000,000 loan commitment under this Agreement and deemed to be an advance
against the Loan Amount for purposes of this Section 5.

         5.2 Consideration for Loan. For each $1,000,000 of the Loan Amount
advanced by Collagen to the Company, Dr. Perkins agrees to sell and transfer to
Collagen, and Collagen agrees to purchase from Dr. Perkins, 25,000 shares of
Common Stock at a purchase price of $.70 per share up to a maximum of 125,000
shares of Common Stock. If the Loan Amount is reduced under Section 5.1(a), then
the maximum number of shares subject to this Section 5.2 shall be reduced on a
prorata basis.

                       2. LIFE OF PATENT EXCLUSIVE GRANT

        2.1 Subject to the limitations set forth in this Agreement, The Regents
hereby grants to Licensee a (worldwide) license under Regents' Patent Rights
and Regents' Proprietary Rights to make, have made, use, and sell Licensed
Products and to practice the Licensed Method.

        2.2 Except as otherwise provided herein, the license granted in section
2.1 shall be exclusive for the life of the Agreement.

        2.3 The Regents expressly reserves the right to use the Invention and
associated technology for educational and research purposes.

                                 3. SUBLICENSES
        
        3.1 The Regents also grants to Licensee the right to issue sublicenses
to third parties to make, have made, use and sell Licensed Products and to
practice the Licensed Method provided Licensee has current exclusive rights
thereto under this Agreement. To the extent applicable, such sublicenses shall
include all of the rights of and obligations due to The Regents that are
contained in this Agreement.

        3.2 Licensee shall provide The Regents with a copy of each sublicense
issued hereunder; collect and guarantee payment of all royalties due The
Regents from sublicensees; and summarize and deliver all reports due The
Regents from sublicensees.

        3.3 Upon termination of this Agreement for any reason, The Regents, at
its sole

                                   APPENDIX A

discretion, shall determine whether any or all sublicenses shall be canceled or
assigned to The Regents.

                              4. LICENSE ISSUE FEE

        4.1 Licensee agrees to pay to The Regents a License Issue Fee of 
[ *** ] according to the following schedule:

          - [ *** ] to be paid within [ *** ] after the execution date of this 
            Agreement

          - [ *** ] to be paid upon submission of Product Market Approval
            (PMA) or 510K data to the U.S. Food and Drug Administration (FDA),
            but no later than [ *** ] 

          - [ *** ] to be paid on [ *** ] and 

          - [ *** ] to be paid upon FDA marketing approval, but no later than
            [ *** ]

        4.2 This license issue fee is non-refundable, non-cancellable, and not

                                  5. ROYALTIES

        5.1 Licensee shall also pay to The Regents an earned royalty of [ *** ]
of the Net Sales of Licensed Products. In the event the last patent application
under this Agreement is abandoned and no patent in Regents' Patent Rights has
issued, Licensee shall pay to The Regents an earned royalty of [ *** ] in the
first full year of commercial sales of Licensed Products covered by Regent's
Proprietary Rights following such abandonment, [ *** ] in the second full year
of such commercial sales following such abandonment, [ *** ] in the third full
year of such commercial sales following such abandonment, [ *** ] in the fourth
year of such commercial sales following such abandonment, and no earned royalty
in subsequent years.

        5.2 For sales of Licensed Products to an Affiliate or Joint Venture
from Licensee at a reduced price from that customarily charged to an unrelated
third party, the royalty paid to The Regents shall be based on the Net Sales of
Licensed Products of the Affiliate or Joint Venture to the Affiliate's or Joint
Venture's customers. Where Licensee transfers Licensed Products for end-use to
itself or an Affiliate or Joint Venture, such transfer shall be considered a
sale at list price, and The Regents shall be entitled to receive a royalty
thereon in accordance with this Article 5, (ROYALTIES). Each reference to
Licensee herein shall be meant to include its Affiliates and Joint Ventures.

        5.3 Paragraphs 1.1, 1.2, 1.3, and 1.4 define Regents' Patent Rights,
Licensed Products, and Licensed Methods so that royalties shall be payable on
products and methods covered by both pending patent applications and issued
patents as well as on products and methods covered by Regents' Proprietary
Rights. Earned royalties shall accrue in each country for the 

***Confidential treatment requested

                                       6
<PAGE>   28
duration of Regents' Patent Rights in that country and shall be payable to The
Regents when Licensed Products are invoiced, or if not invoiced, when delivered
to a third party. In the event the last patent application under this Agreement
in that country is abandoned and no patent in Regents' Patent Rights has issued
for that country then Licensee shall pay to The Regents an earned royalty based
on sales of Licensed Products covered by The Regents' Proprietary Rights in
that country as provided in paragraph 5.1.

        5.4     Royalties accruing to The Regents shall be paid to The Regents 
[ *** ] on or before the following dates [ *** ]:

                                    [ *** ]

                                    [ *** ]

                                    [ *** ]

                                    [ *** ]

Each such payment will be for royalties which accrued within the Licensee's
most recently completed [ *** ].

        5.5     Licensee shall pay to The Regents a minimum annual royalty of 
[ *** ] and [ *** ] thereafter, beginning with the calendar year [ *** ]. This
minimum annual royalty shall be paid to The Regents by [ *** ] of each year and 
shall be credited against the earned royalty (if any) due and owing for the 
calendar year in which the minimum payment was made.

        5.6     Notwithstanding the minimum royalties stated in paragraph 5.5
(Minimum Royalties), in the event the last patent application under this
Agreement is abandoned and no patent in Regents' Patent Rights has issued,
Licensee shall pay to The Regents a minimum annual royalty

*** confidential treatment requested

                                       7

<PAGE>   29
equal to [ *** ] of the minimum royalty stipulated for that year in paragraph
5.5 for the first year of commercial sales following such abandonment, [ *** ]
of the minimum royalty stipulated for that year in paragraph 5.5 for the second
full year of such commercial sales following such abandonment, [ *** ] of the
minimum royalty stipulated for that year in paragraph 5.5 for the third full
year of such commercial sales following such abandonment, [ *** ] of the
minimum royalty stipulated for that year in paragraph 5.5 for the fourth year of
such commercial sales following such abandonment, and no minimum annual royalty
in subsequent years.

        5.7     All monies due The Regents shall be payable in United States
funds collectible at par in San Francisco, California. When Licensed Products
are sold for monies other than United States dollars, the earned royalties will
first be determined in the foreign currency of the country in which such
Licensed Products were sold and then converted into equivalent United States
funds. The exchange rate will be that rate quoted in the Wall Street Journal on
the last business day of the reporting period.

        5.8     Royalties earned with respect to sales occurring in any country
outside the United States shall not be reduced by any taxes, fees, or other
charges imposed by the government of such country on the remittance of royalty
income. The Licensee shall also be responsible for all bank transfer charges.
Notwithstanding this, all payments made by the Licensee in fulfillment of The
Regents' tax liability in any particular country shall be credited against
Earned Royalties, royalties, or fees due The Regents for that country.

        5.9     If at any time legal restrictions prevent the prompt remittance
of part or all royalties by the Licensee with respect to any country where a
Licensed Product is sold, the

*** confidential treatment requested


                                       8
<PAGE>   30
Licensee shall pay such royalties to The Regents from the Licensee's United
States source of funds.

        5.10 In the event that any patent or any claim thereof included within
the Regents' Patent Rights shall be held invalid in a final decision by a court
of competent jurisdiction and last resort and from which no appeal has or can
be taken, all obligation to pay royalties based on such patent or claim or any
claim patentably indistinct therefrom shall cease as of the date of such final
decision. The Licensee shall not, however, be relieved from paying any
royalties that accrued before such decision or that are based on another patent
or claim not involved in such decision or that are based on the Regents'
Proprietary Rights.

                                6. DUE DILIGENCE

        6.1 The Licensee, upon execution of this Agreement, shall diligently
proceed with the development, manufacture, and sale of Licensed Products and
shall earnestly and diligently endeavor to market the same within a reasonable
time after execution of this Agreement and in quantities sufficient to meet the
market demands therefor.

        6.2 The Licensee shall be entitled to exercise prudent and reasonable
business judgment in meeting its due diligence obligations hereunder.

        6.3 The Licensee shall endeavor to obtain all necessary governmental
approvals for the manufacture, use, and sale of Licensed Products.

        6.4 If the Licensee is unable to perform any of the following:

        6.4.1 initiate a pilot animal study for the device by [ *** ]; or

        6.4.2 complete the pilot animal study for the device and, if it is
necessary for

              by December 31, 1994; or

        6.4.3 submit a 510K covering Licensed Products to the United States FDA
              by [ *** ]; or  

        6.4.4 initiate human trials on the device and complete the full animal
              study on the device by [ *** ]; or

        6.4.5 market Licensed Products in the United States within [ *** ] of
              receiving approval of such Licensed Product's 510K or PMA from
              the U.S. FDA; or 

        6.4.6 reasonably fill the market demand for Licensed Products following
              commencement of marketing at any time during the exclusive period
              of this Agreement; 

then The Regents shall have the right and option either to terminate this
Agreement or to reduce the Licensee's exclusive license to a nonexclusive
license. This right, if exercised by The Regents, supersedes the rights granted
in Article 2 (GRANT).

        6.5 In addition to the obligations set forth above, the Licensee shall
spend an aggregate of not less than [ *** ] for the development and
commercialization of Licensed Products during the first 3 years of this
Agreement according to the following schedule:

        1994 [ *** ]

        1995 [ *** ]

        6.6     Either party to this Agreement may refer a dispute arising
under this Article 6 (DUE DILIGENCE) to arbitration. Such referral to
arbitration shall be made by so notifying the other party in writing in
accordance with the provisions of Article 19 hereto (NOTICES), stating the
nature of the dispute to be resolved. Any such arbitration shall be controlled
by the provisions of this Article 6.

        6.7     Within fifteen (15) business days following such notice, three
arbitrators shall be selected by the following process:

        6.7.1   Each Party shall designate one individual, not an employee,
                director, or shareholder of the Party or sublicensee of the
                Party, to serve as an arbitrator.

        6.7.2   These arbitrators shall select a third individual who shall be
                an attorney experienced in arbitration proceedings to serve as
                the third arbitrator and to preside in resolution of the
                dispute. The third arbitrator shall not be an employee,
                director, or shareholder of either Party or sublicensee of
                either Party.

        6.8     Within five (5) business days after selection, the arbitrators
shall meet with the Parties at which time the Parties shall each present in

        6.9     The following general provisions shall apply to the
arbitration proceeding:

        6.9.1   No later than thirty (30) days after the appointment of the
third arbitrator, the arbitrators shall set a date for a hearing to resolve the
issue identified by the Parties.  The hearing shall take place no later than
one hundred twenty (120)


                                       11

        days from the original notice to arbitrate.

6.9.2   The arbitrators shall permit the taking of no more than one (1)
        deposition by each Party, and shall permit, subject to the provisions of
        a mutually agreeable protective order, the production of only those
        documents immediately and directly bearing on the issue or issues
        subject to arbitration and only to the extent necessary for the
        convenience and use of the arbitrators, and shall not require or permit
        any other discovery by any means, including, but not limited to,
        depositions, interrogatories, or production of documents.


6.9.3   No later than ten (10) business days prior to the hearing, each Party
        may submit a single written brief or memorandum in support of its
        position which may be no more than twenty (20) pages. Each Party shall
        be entitled to no more than three (3) hours of hearing to present
        testimony or documentary evidence. Such time limitation shall include
        any direct, cross, or rebuttal testimony, but such time limitation shall
        only be charged against the Party conducting such direct, cross, or
        rebuttal testimony. It shall be the responsibility of the arbitrators to
        determine whether each Party has had the three (3) hours to which it is
        entitled or may, upon good cause shown, have additional time to present
        its case.

6.9.4   Each Party shall have the right to be represented by counsel. The
        arbitrators shall have sole discretion with regard to the admissability
        of evidence. Admissibility will be decided by two-thirds vote.

Party must submit a proposed finding to the arbitrators.

        6.10 The arbitrators shall rule on the disputed issue within thirty
(30) days following the completion of the testimony of both Parties. Such
ruling shall encompass in its entirety the proposed findings of one of the
Parties on the disputed issue. The issue shall be resolved upon two-thirds vote
of the arbitrators.

        6.11 Arbitration shall take place in the location of choice of the
party who has not requested arbitration. All hearing costs for a hearing shall
be shared equally between the Parties.

        6.12 The arbitrators shall be paid reasonable fees plus expenses, which
fees and expenses shall be shared equally by the Parties.

        6.13 The decision of the arbitrators shall be enforceable but not
appealable in any court of competent jurisdiction.

        6.14 To exercise either the right to terminate this Agreement or to
reduce the license to a nonexclusive license for lack of diligence, The Regents
must give the Licensee written notice of the deficiency. The Licensee
thereafter has sixty (60) days to cure the deficiency or to request
arbitration. If The Regents has not received a written request for arbitration
or satisfactory tangible evidence that the deficiency has been cured by the end
of the sixty (60)-day period, then The Regents may, at its option, either
terminate this Agreement or reduce the Licensee's exclusive license to a
nonexclusive license by giving written notice to the Licensee. These notices
shall be subject to Article 19 (NOTICES).

Affiliates.

        7.4     The Licensee also agrees to report to The Regents in its
immediately subsequent progress and royalty report the date of first commercial
sale of a Licensed Product in each country.

the number of each type of Licensed Product sold, (c) the royalties, in U.S.
dollars, payable hereunder with respect to such sales, (d) the method used to

        7.6  If no sales of Licensed Products have been made during any
reporting period, a statement to this effect shall be required.


                             8.  BOOKS AND RECORDS

        8.1  The Licensee shall keep books and records accurately showing all
Licensed Products manufactured, used, and/or sold under the terms of this
Agreement. Such books and records shall be preserved for at least five (5)
years from the date of the royalty payment to which they pertain and shall be
open to inspection by representatives or agents of The Regents at reasonable
times.

        8.2  The fees and expenses of The Regents' representatives performing
such an examination shall be borne by The Regents. However, if an error in
royalties of more than five percent (5%) of the total royalties due for any
year is discovered, then the fees and expenses of these representatives shall
be borne by the Licensee.

parties in accordance with the terms of this Agreement, this Agreement shall be
in force from the effective date recited on page one and shall remain in effect
for the life of the last-to-expire patent licensed under this Agreement, or for

        10.1  If the Licensee should violate or fail to perform any term or
covenant of this Agreement, then The Regents may give written notice of such
default (Notice of Default) to the Licensee. If the Licensee should fail to
repair such default within sixty (60) days of the effective date of such
notice, The Regents shall have the right to terminate this Agreement and the
licenses herein by a second written notice (Notice of Termination) to the
Licensee. If a Notice of


                                       16

<PAGE>   38
Termination is sent to the Licensee, this Agreement shall automatically
terminate on the effective date of such notice. Such termination shall not
relieve the Licensee of its obligation to pay any royalty or license fees owing
at the time of such termination and shall not impair any accrued right of The
Regents. These notices shall be subject to Article 19 (Notices).

                          11.  TERMINATION BY LICENSEE

        11.1    The Licensee shall have the right at any time to terminate this

relieve the Licensee of any obligation of liability accrued hereunder prior to
such termination or rescind anything done by the Licensee or any payments made
to The Regents hereunder prior to the time such termination becomes effective,
and such termination shall not affect in any manner any rights of The Regents
arising under this Agreement prior to such termination. Any unpaid part of the
License Issue Fee of paragraph 4.1 becomes due and payable at the time of
termination by Licensee.

         12.  DISPOSITION OF LICENSED PRODUCTS ON HAND UPON TERMINATION

conferring any right to use in advertising, publicity, or other promotional
activities any name, trade name, trademark, or other designation of either

        13.3    Notwithstanding paragraph 13.2, it is understood that The 
Regents shall be free to release to the inventors and senior administrative 
officials employed by The Regents the terms and conditions of this Agreement
upon their request. If such release is made, The Regents shall request that
such terms and conditions not be disclosed to others. It is further understood

                 or will be free from infringement of patents of third parties; 
                 or

        (14.4.3) an obligation to bring or prosecute actions or suits against
                 third parties for patent infringement except as provided in 
                 Article 17 (PATENT INFRINGEMENT); or

        (14.4.4) conferring by implication, estoppel, or otherwise any license
                 or rights under any patents of The Regents other than Regents' 
                 Patent Rights as defined herein, regardless of whether such 
                 patents are dominant or subordinate to Regent's Patent Rights; 
                 or

        (14.4.5) an obligation to furnish any know-how not provided in Regents'
                 Patent Rights.

                     15. PATENT PROSECUTION AND MAINTENANCE

        15.1 Provided that Licensee has paid billings and rebillings as
provided for in paragraph 15.4, The Regents shall diligently prosecute and
maintain the United States patents comprising Regents' Patent Rights using
counsel of its choice. The Regents' counsel will take instructions only from
The Regents. The Regents shall provide the Licensee with copies of all relevant
documentation so that the Licensee may be informed and apprised of the
continuing prosecution. The Licensee agrees to keep this documentation
confidential. 

        15.2 The Regents shall use all reasonable efforts to amend any patent
application to include claims reasonably requested by the Licensee to protect
the products contemplated to be sold under this Agreement.

        15.3 Licensee shall apply for an extension of the term of any patent
included within 

                                       20
<PAGE>   42
Regents' Patent Rights if appropriate under the Drug Price Competition and
Patent Term Restoration Act of 1984 and/or European, Japanese, and other
foreign counterparts of this law. The Licensee shall prepare all such
documents, and The Regents agrees to execute such documents and to take such
additional action as the Licensee may reasonably request in connection
therewith. 

        15.4 The costs of preparing, filing, prosecuting, and maintaining all
United States patent applications and/or patents contemplated by this Agreement
shall be borne by Licensee. This includes patent prosecution costs for this
Invention incurred by The Regents prior to the execution of this Agreement.
Such prior costs (approximately $8,611.71 as of September 30, 1993) will be due
within thirty (30) days of the execution of this Agreement. Current and future
costs for patent prosecution and maintenance will be billed to the Licensee by
The Regents as incurred and shall be payable within thirty (30) days of the
billing date.

        15.5 The Licensee shall have the right to request The Regents to obtain
patent protection on the Invention in foreign countries if available and if it
so desires. The Licensee must notify The Regents within seven (7) months of the
filing of the corresponding United States application of its decision to obtain
foreign patents. This notice concerning foreign filing shall be in writing,
must identify the countries desired, and reaffirm Licensee's obligation to
underwrite the costs thereof. The absence of such a notice from the Licensee to
The Regents shall be considered an election not to secure foreign rights.

        15.6 The preparation, filing, and prosecuting of all foreign patent
applications filed at the Licensee's request, as well as the maintenance of all
resulting patents, shall be at the sole expense of the Licensee. Such patents
shall be held in the name of the Regents and shall be obtained using counsel of
The Regents' choice.

                                       21
<PAGE>   43
        15.7 The Licensee's obligation to underwrite and to pay patent
prosecution costs shall continue for so long as this Agreement remains in
effect provided, however, that the Licensee may terminate its obligations with
respect to any given patent application or patent upon three (3) months written
notice to The Regents. The Regents will use its best efforts to curtail patent
costs when such a notice is received from the Licensee. Those costs which
cannot be curtailed will be due and owing when rebilled. The Regents may
continue prosecution and/or maintenance of such application(s) or patent(s) at
its sole discretion and expense provided, however, that the Licensee shall have
no further right or licenses thereunder.

        15.8 The Regents shall have the right to file, prosecute, or maintain 
patent applications at its own expense in any country in which the Licensee has
not elected to file, prosecute, or maintain patent rights in accordance with
this Article 15, and such applications and resultant patents shall not be
subject to this Agreement.

                               16. PATENT MARKING

        16.1 The Licensee agrees to mark all Licensed Products made, used, or
sold under the terms of this Agreement, or their containers, in accordance with
the applicable patent marking laws.

                            17. PATENT INFRINGEMENT

        17.1 In the event that the Licensee shall learn of the substantial
infringement of any patent or patent extension licensed under this Agreement,
the Licensee shall call The Regents' attention thereto in writing and shall
provide The Regents with reasonable evidence of such

                                       22
 
<PAGE>   44
infringement. Both parties to this Agreement agree that during the period and
in a jurisdiction where the Licensee has exclusive rights under this Agreement,
neither will notify a third party of the infringement of any of Regents' Patent
Rights without first obtaining consent of the other party, which consent shall
not be unreasonably denied. Both parties shall use their best efforts in
cooperation with each other to terminate such infringement without litigation.

        17.2 The Licensee may request that The Regents take legal action
against the infringement of Regents' Patent Rights. Such request shall be made
in writing and shall include reasonable evidence of such infringement and
damages to the Licensee. If the infringing activity has not been abated within
ninety (90) days following the effective date of such request, The Regents
shall have the right to:

             a) commence suit on its own account or

             b) refuse to participate in such suit,

and The Regents shall give notice of its election in writing to the Licensee by
the end of the one-hundredth (100th) day after receiving notice of such request
from the Licensee. The Licensee may thereafter bring suit for patent
infringement if and only if The Regents elects not to commence suit and if the
infringement occurred during the period and in a jurisdiction where the
Licensee had exclusive rights under this Agreement. However, in the event the
Licensee elects to bring suit in accordance with this paragraph, The Regents
may thereafter join such suit at its own expense.

        17.3 Such legal action as is decided upon shall be at the expense of
the party on account of whom suit is brought and all recoveries recovered
thereby shall belong to such party provided, however, that legal action brought
jointly by The Regents and the Licensee and fully

                                       23
<PAGE>   45
participated in by both shall be at the joint expense of the parties and all
recoveries shall be shared jointly by them in proportion to the share of
expense paid by each party.

        17.4    Each party agrees to cooperate with the other in litigation
proceedings instituted hereunder but at the expense of the party on account of
whom suit is brought. Such litigation shall be controlled by the party bringing
the suit except that The Regents may be represented by counsel of its choice
pursuant to The Regents' determination in any suit brought by the Licensee.

                              18.  INDEMNIFICATION

        18.1    The Licensee agrees to indemnify, hold harmless, and defend The
Regents, their officers, employees, and agents; the sponsors of the research
that led to the Invention; and the inventors of the patents and patent
applications in Regents' Patent Rights and their employers against any and all
claims, suits, losses, damage, costs, fees, and expenses resulting from or
arising out of exercise of this license or any sublicense. This indemnification
will include, but will not be limited to, any product liability.

        18.2    The Licensee, at its sole cost and expense, shall insure its
activities in connection with the work under this Agreement, and before
Licensee conducts any non-financial commercialization activities concerning the
Licensed Products outside of development and trials performed at the University
of California by employees of the University of California, Licensee  shall
obtain, keep in force, and maintain Comprehensive or Commercial Form General
Liability Insurance (contractual liability included) or an equivalent program
of self-insurance with limits as follows:


                                       24

        It should be expressly understood, however, that the coverages and
limits referred to under the above shall not in any way limit the liability of
Licensee. Licensee shall furnish The Regents with certificates of insurance
evidencing compliance with all requirements. Such certificates shall:

                (18.2.1)        Provide a thirty (30)-day advance written
                                notice to the University of any modification.

                (18.2.2)        Indicate that The Regents has been endorsed as
                                an additional insured under the coverages 
                                referred to under the above.

                (18.2.3)        Include a provision that the coverages will be
                                primary and will not participate with nor will
                                be excess over any valid and collectible
                                insurance or program of self-insurance carried
                                or maintained by The Regents.

        18.3    The Regents shall promptly notify Licensee in writing of
any claim or suit brought against The Regents in respect of which The Regents
intends to invoke the provisions of this Article 18. Licensee will keep The
Regents informed on a current basis of its defense of any claims pursuant to
this Article 18.

                                  19.  NOTICES

        19.1    Any notice or payment required to be given to either party

and agreements as are necessary in order to give effect to the provisions of

Effective Date.

         3.2. Term.

         (a)  Unless this Agreement is sooner terminated, in its entirety or as

Territory by either party, by written notice to the other party, in the event
that (i) a mutual decision not to Launch the Agreement Product in such country
is reached or (ii) a Launch is not commenced with respect to such country within
* after the time period set forth on Exhibit B.

         (d) In the event that in any Agreement Year commencing with the *
Agreement Year (and so long as (i) no force majeure condition of the Distributor
exists at such time pursuant to Section 20, (ii) Biomatrix has met its supply
obligations under Section 7.4, and (iii) Distributor is able to lawfully sell
the Agreement product and any Improved Agreement Product(s) in each of the
countries within any such Region), the Distributor's (and its Affiliates' or
Subdistributors', as applicable) Net Retail Sales of the Agreement Product and
any Improved Agreement Product(s) in any Region comprise less than * in such

rights (including, without limitation, its right to use the Trademarks) under
this Agreement for the Agreement Product and any Improved Agreement Product(s)

Tissue Augmentation Products in a Region in a given Agreement Year were * , and
Distributor's Net Retail Sales of the Agreement Product in such Region in such
Agreement Year were $500, *;

election, Biomatrix may *  

         Upon any such termination of the Distributor's distribution rights in a
Region, the Distributor's obligation to pay any royalties pursuant to Sections
8.1 and 8.2 for any sales in such Region after such termination shall cease, but
the Distributor shall remain obligated to pay all such royalties for sales in
such Region accrued prior to such termination.

         (e)  If the Distributor's rights to distribute the Agreement Product
and any Improved Agreement Product(s) in any country in the European Territory
shall terminate solely pursuant to subsection (d) above, Biomatrix agrees to
sell the Agreement Product and any Improved Agreement Product(s) developed
before the date of such termination to the Distributor a * for the period of
time equal to the period that would have remained in the Initial Term in such
country had the Distributor's distribution rights not terminated.

         3.3. Inventory.

         (a)  Upon termination of this Agreement for any reason, Biomatrix shall
have the right (but not the obligation) to repurchase all or part of the
inventory of the Agreement Product and any Improved Agreement Product(s) held by
the Distributor or its Affiliates or Subdistributors.

         (b)  The price for inventory to be repurchased by Biomatrix pursuant to
Section 3.3(a) above shall be the landed cost thereof actually paid by the
Distributor to Biomatrix. With respect to any quantities not repurchased by
Biomatrix, the Distributor shall have the right to sell such inventory of the
Agreement Product and any Improved Agreement Product(s), in its usual and
customary manner, in the ordinary course of business, for a period of six (6)
months following termination of this Agreement and notwithstanding such
termination the terms and conditions of this Agreement shall apply to such
sales.

         3.4. Insolvency. This Agreement may be immediately terminated as to the
entire Territory by either party, upon giving written notice to the other party,
in the event that the other party shall become insolvent or be declared bankrupt
by a court of competent jurisdiction or shall be the subject of any
reorganization (other than a corporate reorganization effected in the ordinary
course of business and not arising out of any insolvency) or winding up,
receivership or dissolution, bankruptcy or liquidation proceeding, or any

proceeding or action similar to one or more of the above, in which case
termination shall be effective upon such written notice. The failure of either
party to give notice of termination upon obtaining knowledge of any such event
shall not be interpreted as a waiver of such party's rights under this Section
3.4, and such party reserves the right to exercise any such rights at any time
after the occurrence of any such event.

         3.5. Breach. This Agreement may be terminated as to the entire
Territory by either party if the other party shall breach any of its payment
obligations hereunder or with respect to any Region if Distributor (or its
Affiliates or Subdistributors, as applicable) shall commit a material breach of
any of its warranties, covenants, conditions, obligations or agreements
contained herein with respect to such Region, provided that such breach shall
continue for a period of thirty (30) days after written notice thereof and
provided further that such termination shall be immediately effective upon
further written notice to that effect to the breaching party after its failure
to cure such breach within such applicable notice period. For avoidance of
doubt, the parties agree that if a Launch is not reached with respect to a
country within thirty days after the time period set forth on Exhibit B, then
either party may terminate this Agreement with respect to such country (provided
that such failure to reach a Launch is not caused by a force majeure condition
of the Distributor or Biomatrix's failure to meet its supply obligations under
Section 7.4).

         3.6. Certain Rights Upon Termination. Upon termination of this
Agreement for any reason whatsoever, Biomatrix shall have the following rights,
or if such termination is as to a country in the Territory in accordance with
the provisions of this Agreement, Biomatrix shall have the following rights in

information required to be provided to Biomatrix by law, information relating to
laboratory, animal and human studies, and related regulatory approvals
pertaining to the Agreement Product or any Improved Agreement Product(s) (the
"Information") which are possessed or controlled by the Distributor or any of
its Affiliates or Subdistributors, or to which the Distributor or any of its
Affiliates or Subdistributors has a right to review, access or use. The
Distributor unconditionally agrees promptly to take any action and to execute
and deliver to Biomatrix any documents or instruments reasonably requested by
Biomatrix to permit Biomatrix to make full use of such unrestricted right.

         (b)  Further, Biomatrix shall have exclusive ownership rights to the
Trademarks and to all other product specific logos, slogans and other
intangibles used by the Distributor solely in association with the independent
sale of the Agreement Product and any Improved Agreement Product(s) (including

or any of its Affiliates or Subdistributors, and the Distributor unconditionally
agrees, subject to the provisions of Section 3.3(b), (i) immediately upon
termination to cease using the Trademarks and any such logos, slogans, and
marketing rights of Biomatrix or any imitations thereof and (ii) immediately to
execute and deliver to Biomatrix any documents or instruments reasonably
requested by Biomatrix to give full effect to the provisions of this Section
3.6; provided, however, if the Distributor maintains a license to distribute the
Agreement Product(s) in (a) two Regions, (b) one Region in the European
Territory or (c) in the United States, then Distributor shall retain the
exclusive rights in the Trademarks in the entire Territory.

         (c)  In addition, the Distributor unconditionally agrees, subject to
the provisions of Section 3.3(b), that it shall, upon the request of Biomatrix,
immediately inform all relevant regulatory authorities that the Distributor (or
its Affiliate or Subdistributor) is no longer a distributor of the Agreement
Product or the Improved Agreement Product(s) and shall take all action and
execute and deliver all documents and instruments necessary in order to transfer
to the fullest extent permitted under applicable law all registrations and
Product License Approvals, or applications therefor, for the Agreement Product
or any Improved Agreement Product(s) to Biomatrix or any Person nominated by
Biomatrix.

         3.7. Effects of Termination.

shall immediately discontinue making any representations regarding its status as
a distributor for Biomatrix and shall immediately cease conducting any
activities with respect to the marketing, promotion, sale or distribution of the
Agreement Product and any Improved Agreement Product(s), provided, however, that
the Distributor shall be permitted to sell inventory not repurchased by
Biomatrix in accordance with Section 3.3.

         (b)  Termination of this Agreement shall not affect obligations of
either party that may have accrued prior to the effective date of termination.
Subject to Clause 3.8 below, termination of this Agreement shall be in addition
to, and shall not be exclusive of or prejudicial to, any other grounds for
termination or rights or remedies at law or in equity which either party may
have on account of any default of the other party.

         3.8. Waiver. The Distributor (for itself and on behalf of its
Affiliates and Subdistributors) hereby waives, to the extent it is able to do so
under the law of every country in the Territory and other applicable law, any
statutory rights it may have or acquire in respect of the termination of the
relationship established hereby pursuant to the terms hereof, and agrees that
the rights available to it hereunder in the event of such termination are
adequate and reflect the agreement of the parties. The Distributor shall not
have any right to claim any indemnity for goodwill or lost profits or any
damages arising from the rightful termination of this Agreement in accordance
with the terms hereof.

         4.  PAYMENTS. All payments hereunder shall be made in Dollars. Payments

of any such remittance shall be borne by the Distributor. All amounts (except

if The Wall Street Journal shall no longer publish such exchange rates, as
determined by a method that is mutually agreed upon in writing by the parties).

         5.  WITHHOLDING. All payments to be made by the Distributor under this
Agreement shall be made in full, free and clear of and without any deduction of
or withholding for or on account of any taxes levied in any country of the
Territory or elsewhere; provided that if the Distributor shall be required by
law to make any deduction or withholding from any payment to Biomatrix then:

does not exceed the minimum legal liability therefor; and

         (b)  not later than five (5) days before each deduction or withholding
of any taxes, the Distributor shall forward to Biomatrix such documentary
evidence as may be required by Biomatrix in respect of the proposed deduction,
withholding or payment; and

hereby licenses to the Distributor the right to use, and hereby requires solely
in association with the independent sale by the Distributor of the Agreement
Product and any Improved Agreement Products the use of, the Trademarks in the
Territory during the term of this Agreement. The Distributor warrants that it
shall not use any of the Trademarks at any time outside the Territory or use any
of the Trademarks for any products other than the Agreement Product and any
Improved Agreement Product(s) within the Territory. The Distributor shall not
use a trademark or other mark (other than a Trademark) in connection with its

Territory in which the Distributor, any of its Affiliates or any Subdistributor
is selling the Agreement Product and/or any Improved Agreement Product. The
parties shall execute a short form Trademark assignment agreement to the extent
that it is necessary to record the Trademark license under this Section 6.1 in
any country whose laws require any such registration.

the like as well as information regarding adverse events associated with the use

Biomatrix and the Distributor and shall meet * . In the event of a dispute

         (c)  Biomatrix shall reimburse Distributor for all direct costs and
expenses (including without limitation shipping, quality control testing and
notification costs) incurred by Distributor and its Affiliates as a result of
any recall, except where such recall (i) is the result of the failure of
Distributor or its Affiliates or Subdistributors to comply with their
obligations under this Agreement and/or (ii) was opposed by Biomatrix and proved
to be unwarranted, in which case Distributor shall reimburse Biomatrix for all
direct costs and expenses (including without limitation shipping, quality
control testing and notification costs) incurred by Biomatrix and its Affiliates

         7.2. Price; Adjustment; Reports; Payment.

         (a)  The parties shall attempt in good faith to agree in writing, prior
to the Launch in each country, upon mutually acceptable supply pricing for the
Distributor's purchase of the Agreement Product and any Improved Agreement
Product(s), but such pricing in any event shall not be less than the greater of
(i) the Minimum Price, or (ii) the Formula Price, except as provided in
subsection (b) below. The parties shall attempt in good faith to agree in
writing upon mutually acceptable minimum pricing for the Agreement Product in
sizes other than the 1.0cc Treatment Syringe and for any Improved Agreement
Product(s). For any syringe with a fill volume of greater than one cc(1cc), the
Minimum Price shall be the amount calculated as * plus the dollar amount which
equals * of such product with a larger fill volume * of the one cc(1cc) syringe.
In the event that Biomatrix's actual incremental Cost of Goods Sold exceeds such
dollar amount, the Minimum Price shall be the amount calculated as * . Subject
to the general commercial availability of appropriate syringes for the Agreement
Product, the * for a one and one-half (1.5)cc syringe, * for a two (2.0)cc
syringe, and * for a two and one-half (2.5)cc syringe.

         (b)  If Biomatrix has appointed a new distributor for a country in the
Territory pursuant to Section 2.3 and the Distributor has the right to
distribute the Agreement Product and any Improved Agreement Product(s) in such
country, the supply pricing for the Distributor's purchase of the Agreement
Product and any Improved Agreement Product(s) for resale in such country *


         (c)  The price initially payable by the Distributor to Biomatrix for
each unit of the Agreement Product during each month of each Agreement Year

in accordance with Section 7.2(e) below).

         (d)  Within * after the end of each month of each Agreement Year for
each country in the Territory, the Formula Price for the Agreement Product in

Subdistributors) in such country during such monthly period, such payment to be

end of such Contract Quarter and Agreement Year. The price calculated annually
in this manner shall be the final price payable for all units of the Agreement
Product sold by the Distributor, any Affiliates or Subdistributors of
Distributor during such Agreement Year. For the avoidance of doubt, the
aggregate amount payable by Distributor for the Agreement Product(s) and any
Improved Agreement Product(s) in any country for any Agreement Year shall in no
event be lower than the Minimum Price multiplied by the total units sold in such
Agreement Year in such country.

         (f) Within * following the end of each calendar month in each Agreement
Year, the Distributor shall submit to Biomatrix written reports detailing the

Retail Sales and aggregate number of units sold of the Agreement Product and any
Improved Agreement Product(s) in each country in the Territory during the
immediately preceding calendar month.

Agreement Product(s) during the immediately preceding Agreement Year, which
reports shall contain the Net Retail Sales of the Agreement Product and any
Improved Agreement Product(s) in each country in the Territory, and the
aggregate number of units of the Agreement Product and any Improved Agreement

         7.3. Sales and Supply Forecasts; Accounts.

         (a)  Exhibit D, which shall be supplied by the Distributor within * of
the Effective Date, sets forth a sales forecast of units of the Agreement
Product in the Territory for the first year after the Effective Date.

         (b)  Within * after the end of each month, the Distributor shall
provide to Biomatrix an updated rolling twelve (12) month monthly supply
forecast for all unit sizes of the Agreement Product in the Territory. Each such
supply forecast described in this subsection (b) is referred to herein as a
"Supply Forecast"; provided, that updated Supply Forecasts shall not vary
(whether up or down) from the immediately preceding Supply Forecast by more than
* with respect to each month covered by such preceding Supply Forecast.

         (c)  The Distributor shall maintain, and shall require its Affiliates
and Subdistributors to maintain, books of account with respect to sales of the
Agreement Product in the Territory by it and its Affiliates and Subdistributors.
Biomatrix shall have the right, not more than once during each calendar year, to
have an independent accountant selected and retained by Biomatrix (reasonably
acceptable to the Distributor, provided that any "big six" accounting firm shall
be deemed reasonable) to inspect and examine such books of the Distributor, its
Affiliates and Subdistributors during regular business hours for the purpose of
verifying the statements of the aggregate Net Retail Sales of all Dermal Tissue
Augmentation Products for all purposes hereunder, including verification of
Formula Price and the royalties described in Section 8. The cost of each such
audit shall be borne by Biomatrix unless a material error is discovered in the
course of such audit, in which case the cost shall be borne by the Distributor.
For purposes of this Section 7.3(d), a material error shall be defined as an
understatement of five percent (5%) or more of the aggregate amount owed to
Biomatrix with respect to sales of Dermal Tissue Augmentation Products in a
country in the Territory. Any additional payments required as a result of such
inspection and examination shall be immediately paid to Biomatrix and shall bear
interest from the date such amount would otherwise have been paid until the date
of actual payment at the rate per annum set forth in Section 20. Such
independent accounting firm shall conduct such inspections and examinations
under conditions of confidentiality.

         7.4. Shipment and Delivery; Packaging.

         (b)  The Distributor shall submit a firm purchase order setting forth
the quantities, delivery date and shipping instructions with respect to each
shipment of the Agreement Product and any Improved Agreement Product(s), such
purchase orders to be received by Biomatrix at least * prior to the requested
delivery date; provided that the Distributor shall not submit any purchase order
for fewer than * units of the Agreement Product or the Improved Agreement
Product(s) (although multiple delivery sites for purchase orders shall be
allowed). Biomatrix shall use commercially reasonable efforts but shall have no
obligation to supply Distributor with quantities of the Agreement Product(s) and
Improved Agreement Product(s) in excess of the amounts in the then current
Supply Forecast for the relevant monthly period. For avoidance of doubt, so long
as Biomatrix supplies Distributor with quantities of the Agreement Product and
Improved Agreement Product(s) as set forth in the Supply Forecast, then
Biomatrix shall not be deemed to be in default under this section or any other
provision of this Agreement relating to Biomatrix's supply obligations. In
addition to the foregoing, within * , in consideration for which units the
Distributor shall pay to Biomatrix a price of * per unit.

         (c)  Biomatrix agrees that with respect to languages for packaging for
the European Territory three separate forms of packaging shall be made

                    Italian;

              (ii)  Southern Europe - English, Italian, Spanish, Portuguese and
                    Greek; and

              (iii) Scandinavia - English, Swedish, Norwegian, Danish and
                    Finnish.

         (d)  Each unit of the Agreement Product and any Improved Agreement
Products shipped to the Distributor shall have, as of the time of delivery, a
remaining shelf life of no less than * less than the maximum shelf life for such
product, as approved by the United States Food and Drug Administration.
Biomatrix shall continually use its best efforts at all times during the term
hereof to lengthen to * the shelf life of the Agreement Product and any Improved
Agreement Products to the extent supported by stability data. Biomatrix' "best
efforts" in this section shall mean that Biomatrix shall use such methods,
exercise such degree of effort and diligence, and adhere to such standards as
are commercially reasonable.

and any Improved Agreement Product(s) sold hereunder shall remain in Biomatrix
until delivery of the Agreement Product and any Improved Agreement Product(s) to
Distributor or its agent and acceptance thereof and upon such delivery and
acceptance the title to such Agreement Product and any Improved Agreement
Product(s) shall, without further action, be transferred to and vested in the
Distributor.

         7.6. Risk of Loss. Biomatrix shall bear all risk of loss of, or damage
to, all units of the Agreement Product and any Improved Agreement Product(s) to

nominees or agents. The Distributor shall bear all risk of loss of, or damage
to, all units of the Agreement Product and any Improved Agreement Product(s)

with Section 7.4.

         7.7. Acceptance, * . All units of the Agreement Product and Improved
Agreement Products delivered to Distributor pursuant to this Agreement shall be
* , the specifications listed in Exhibit A. Any non-conformity which arises
after acceptance by Distributor directly associated with product specification
shall be the responsibility of Biomatrix unless such non-conformity is due to
improper storage conditions subsequent to delivery of the Agreement Product. All
other non-conformities of the Agreement Product shall be the responsibility of
the Distributor. Biomatrix and the Distributor agree to consult with each other
in order to resolve the discrepancy between each other's determinations. If such
consultation does not resolve the discrepancy, the parties agree to nominate a
reputable independent laboratory, acceptable to both parties, that shall carry
out tests on representative samples taken from such shipment, and the results of
such tests shall be binding on the parties. Biomatrix shall at its expense
replace any such shipment to the extent that it does not conform to the
Agreement Product Specifications. All defective units of the Agreement Product
or any Improved Agreement Product(s) shall be returned to Biomatrix at the
address set forth in Section 23 of this Agreement, accompanied or preceded by a
reasonably detailed statement of the claimed defect or non- conformity and proof
of date of purchase, and packed and shipped according to instructions provided
by Biomatrix. The shipping costs of any such returned units shall be borne by
Biomatrix, unless such units are determined not to be defective under the terms
of this Agreement, in which case such shipping costs shall be borne

Territory relating to the manufacture, labelling, packaging and testing of the
Agreement Product, and shall be manufactured for use for the indications
specified in the applicable Product License Approvals therefor.

Improved Agreement Product(s) as applicable, provided that such units are

EVENT WHATSOEVER SHALL BIOMATRIX HAVE ANY LIABILITY, OBLIGATION OR
RESPONSIBILITY FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY
DAMAGES ARISING IN ANY WAY IN CONNECTION WITH THE AGREEMENT PRODUCT OR ANY

* . Such royalty shall commence with respect to each country in the Territory at
the earlier of (a) the Launch of the Agreement Product in such country or (b)
the Launch date for such country set forth on Exhibit B; provided that if a

Tissue Augmentation Products in such country in each Agreement Year over a base
year amount comprised of Net Retail Sales of Dermal Tissue Augmentation Products
in the twelve (12) months immediately preceding the first commercial sale of
either the Agreement Product or any Improved Agreement Product(s) in such
country:

          Increase in Total                 Royalty on Total

Agreement Product have become non-exclusive with respect to such country
pursuant to Section 2.3 or have terminated pursuant to Section 3.2(d). The
Incremental Royalty shall be paid by not later than * after the end of each
Agreement Year. For the avoidance of doubt, if the Distributor had no sales of

                     agreement and any and all agreements relating thereto and a

               (iii) Distributor's filing of an application (either alone or in
                     conjunction with a third party) for marketing approval with
                     the United States Food and Drug Administration or an
                     equivalent regulatory agency in any country with respect to

conduct at its cost any clinical trials required for the marketing and sale of
the Agreement Product and any Improved Agreement Product(s) in each country in
the Territory, except for the European Territory, throughout the term of this
Agreement. "Best efforts" in this context shall mean such that Distributor shall

<PAGE>   33
submit such dispute to their respective presidents by notice delivered in
accordance with the provisions of Section 23, and if within thirty (30) days, or
such other period as is agreed upon in writing by the parties hereto, following
such reference the dispute remains unresolved, to submit the dispute for
arbitration in Boston, Massachusetts under the Rules of the American Arbitration
Association in effect on the date of this Agreement (the "Rules") by arbitrators
appointed in accordance with said Rules. Any decision of such arbitrators shall
be written and shall be final and binding upon the parties. In any arbitration
pursuant to this Section the award shall be rendered by a majority of three (3)
arbitrators, one (1) of whom shall be appointed by each party and the third of
whom shall be appointed by mutual agreement of the two (2) party-appointed
arbitrators. In the event of failure of a party to appoint an arbitrator within
thirty (30) days after commencement of the arbitration proceeding or in the
event of failure of the two (2) party-appointed arbitrators to agree upon the
appointment of the third arbitrator within sixty (60) days after commencement of
the arbitration proceeding, such arbitrator shall be appointed by the American
Arbitration Association in accordance with the Rules. The arbitrators shall
apply the governing law set forth in this Section. Judgment upon an award
rendered by the arbitrators may be entered in any court having jurisdiction
thereof.

         (b)   Each of the parties hereto acknowledges and agrees that damages
will not be an adequate remedy for any material breach or violation of this
Agreement if such material breach or violation would cause immediate and
irreparable harm (an "Irreparable Breach"). Accordingly, notwithstanding the
provisions of Section 18(a) to the contrary, in the event of a threatened or
ongoing Irreparable Breach, each party hereto shall be entitled to seek, in any
state or federal court in the State of New York, equitable relief of a kind
appropriate in light of the nature of the ongoing threatened Irreparable Breach,
which relief may include, without limitation, specific performance or injunctive
relief; provided, however, that if the party bringing such action is
unsuccessful in obtaining the relief sought, the moving party shall pay the
non-moving party's reasonable costs, including attorney's fees, incurred in
connection with defending such action. Such remedies shall not be the parties'
exclusive remedies, but shall be in addition to all other remedies provided in
this Agreement.

         19.   SEVERABILITY. In the event that any provision of this Agreement
shall be held by a court of competent jurisdiction or by any governmental body
to be invalid or unenforceable, such provision shall be deemed severable and the
remaining parts and provisions of this Agreement shall remain in full force and
effect.

         20.   FORCE MAJEURE. Each of the parties shall be excused from the
performance of its obligations hereunder in the event such performance is
prevented by force majeure, and such excuse shall continue as long as the
condition constituting such force majeure continues. For the purpose of this
Agreement, force majeure is defined as contingencies beyond the reasonable
control of either party, including, without limitation, acts of God, judicial or
regulatory action, war, civil commotion, destruction of production


                                      -33-
<PAGE>   34
facilities or materials by fire, earthquake or storm and labor disturbances
(whether or not any such labor disturbance is within the power of the affected
party to settle).

         21.   INTEREST. Any overdue amounts payable by either party hereunder
shall bear interest compounded monthly at the prime lending rate for Dollars
published from time to time in The Wall Street Journal plus * per annum, or, if
lower, the highest rate permissible by applicable law, from the due date until
the date of payment.

         22.   NO PARTNERSHIP OR AGENCY.  This Agreement and the relations
hereby established by and between Biomatrix and the Distributor do not
constitute a partnership, joint venture, agency or contract of employment
between them.

         23.   NOTICES. All communications in connection with this Agreement
shall be in writing and sent by postage prepaid first class mail, courier, or
telefax, and if relating to default, late payment or termination, by certified

have designated by notice to the communicating party. The date of giving any
notice shall be the date of its actual receipt.

         24.   EU REGULATIONS. It is the intention of the parties hereto that
this Agreement shall at all times qualify for the exemption from the provisions
of Article 85(1) of the Treaty of Rome dated 25 March, 1957, as amended, which
either (a) is available under EEC Regulation Number 1983/83, or (b) may
subsequently be available under any successor regulation or regulations thereto.
In the event that any provision of this Agreement is deemed to violate the
conditions for qualifying for the exemption, set out in whichever of those
regulations may be in effect at the relevant time, or if any such regulation is
amended after the date of this Agreement so as to cause this Agreement to fail
to qualify for the exemption, the parties hereto agree that they will, as soon
as it is practicable to do so, enter into good faith negotiations to amend this
Agreement as necessary in order to re-qualify for the exemption or to notify the
Agreement. If those negotiations are not successfully concluded within a
reasonable time (not to exceed ninety (90) days, or such other period as is
agreed upon in writing by the parties hereto, after the relevant regulation is
amended), either party may terminate this Agreement upon written notice to the
other party.

         25.   SURVIVAL. The provisions of Sections 3.3, 3.6, 3.7, 3.8, 6.2,
9.1, 9.2, 9.3, 9.4 and 9.5 of this Agreement shall survive the termination or
expiration of this Agreement (as the case may be) and shall remain in full force
and effect. The provisions of this Agreement that do not survive termination or
expiration hereof (as the case may be) shall, nonetheless, be controlling on,
and shall be used in construing and interpreting


                                      -34-
<PAGE>   35
the rights and obligations of the parties hereto with regard to, any dispute,
controversy or claim which may arise under, out of, or in connection with this
Agreement.

         26.   MISCELLANEOUS. This Agreement sets forth the entire agreement
between the parties with respect to the transactions and arrangements
contemplated hereby and supersedes all prior oral or written arrangements. This
Agreement may be modified or amended only by a written instrument executed and
delivered by both parties. None of the provisions of this Agreement shall be
deemed to have been waived by any act or acquiescence on the part of either
party except by an instrument in writing signed and delivered by the party
executing the waiver. This Agreement may be executed in several identical
counterparts, each of which shall be an original, but all of which constitute
one instrument, and in making proof of this Agreement it shall not be necessary
to produce or account for more than one such counterpart.

not in material breach of any of its obligations under this Agreement.
Thereafter, the appointment of the Distributor as exclusive distributor of the
Agreement Product shall be renewable upon the expiration of such additional *
term, upon written notice to Biomatrix received at least * prior to the end of
such term for one additional consecutive renewal term of * , provided that, as

terminate upon the * of the Effective Date. Subject to the terms of this
Agreement, Distributor shall have the right to continue to sell the Agreement
Product and any Improved Agreement Products it is then currently selling.

         (c)  This Agreement may be terminated by either party, by written
notice to the other party, in the event that (i) a mutual decision not to Launch
the Agreement Product in such country is reached or (ii) a Launch is not
commenced within the time period set forth on Exhibit B.

         (d)  In the event that in any Agreement Year after and including the *
Agreement Year (and so long as (i) no force majeure condition of Distributor
exists at such time pursuant to Section 20, (ii) Biomatrix has met its supply
obligations under Section 7.4, and (iii) Distributor is able to lawfully sell
the Agreement Product and any Improved Agreement Product(s) in the Territory),

shall cease, but the Distributor shall remain obligated to pay all such
royalties for sales in the Territory accrued prior to such termination.

         (e)  Notwithstanding any other provision of this Agreement to the
contrary, Biomatrix may terminate this Agreement at any time prior to receipt of
the Approved Letter (as defined hereafter) from the U.S. Food and Drug
Administration if Distributor is in material breach of the International
Agreement, which material breach has not been cured within thirty (30) days
after written notice of such breach is received by Distributor. The parties
expressly agree that Distributor's failure to meet or adhere to the launch
schedule for the Agreement Product for each country as set forth in the
International Agreement shall be deemed a material breach of the International
Agreement except to the extent that Distributor's failure to meet such launch
schedule is due to (i) Biomatrix's failure to meet its supply obligations under
the International Agreement, (ii) a force majeure condition of the Distributor,
or (iii) it being unlawful for the Distributor to sell the Agreement Product or
any Improved Agreement Product in the Territory, provided that such unlawfulness
is not the result of any act or failure to act of the Distributor.

         (f)  Notwithstanding any other provision in this Agreement to the
contrary, the Distributor may terminate this Agreement upon notice to Biomatrix
of the Distributor's decision not to pay the fee called for in Section 7.1(b).

         3.3. Inventory.

         (a)  Upon termination of this Agreement for any reason, Biomatrix shall
have the right (but not the obligation) to repurchase all or part of the
inventory of the Agreement Product and any Improved Agreement Product(s) held by
the Distributor or its Affiliates.

         (b)  The price for inventory to be repurchased by Biomatrix pursuant to
Section 3.3(a) above shall be the landed cost thereof actually paid by the
Distributor to Biomatrix. With respect to any quantities not repurchased by
Biomatrix, the Distributor shall have the right to sell such inventory of the
Agreement Product and any Improved Agreement Product(s), in its usual and
customary manner, in the ordinary course of business, for a period of six (6)
months following termination of this Agreement and notwithstanding such
termination the terms and conditions of this Agreement shall apply to such
sales.

         3.4. Insolvency. This Agreement may be immediately terminated by either
party, upon giving written notice to the other party, in the event that the
other party shall become insolvent or be declared bankrupt by a court of
competent jurisdiction or shall be the subject of any reorganization (other than
a corporate reorganization effected in the ordinary course of business and not
arising out of any insolvency) or winding up, receivership or dissolution,
bankruptcy or liquidation proceeding, or any proceeding or action similar to

                                      -8-
<PAGE>   52
one or more of the above, in which case termination shall be effective upon such
written notice. The failure of either party to give notice of termination upon
obtaining knowledge of any such event shall not be interpreted as a waiver of
such party's rights under this Section 3.4, and such party reserves the right to
exercise any such rights at any time after the occurrence of any such event.

         3.5. Breach. This Agreement may be terminated by either party if the
other party shall breach any of its payment obligations hereunder or if
Distributor shall commit a material breach of any of its warranties, covenants,
conditions, obligations or agreements contained herein, provided that such
breach shall continue for a period of thirty (30) days (ten (10) days in the
event that such breach is the failure of the Distributor to pay the fee called
for in Section 7.1(b)) after written notice thereof and provided further that
such termination shall be immediately effective upon further written notice to
that effect to the breaching party after its failure to cure such breach within
such applicable notice period. For avoidance of doubt, the parties agree that if
a Launch is not reached within thirty days after the time period set forth on
Exhibit B, then either party may terminate this Agreement (provided that such
failure to reach a Launch is not due to (i) a force majeure condition of the
Distributor, (ii) Biomatrix's failure to meet its supply obligations under
Section 7.4, or (iii) it being unlawful for the Distributor to sell the
Agreement Product or any Improved Agreement Product in the Territory, provided
that such unlawfulness is not the result of any act or failure to act of the
Distributor).

Agreement for any reason whatsoever, Biomatrix shall have the following rights:

adequate and reflect the agreement of the parties. The Distributor shall not

Product(s). For any syringe with a fill volume of greater than one cc (1cc), the
Minimum Price shall be the amount calculated as * plus the dollar amount which

Quarter and Agreement Year, such payment to be made within * after the end of
such * period following the end of such Contract Quarter and Agreement Year. The

Retail Sales of all Dermal Tissue Augmentation Products for all purposes
hereunder, including verification of Formula Price and the royalties described

material error is discovered in the course of such audit, in which case the cost
shall be borne by the Distributor. For purposes of this Section 7.3(d), a
material error shall be defined as an understatement of five percent (5%) or
more of the aggregate amount owed to Biomatrix with respect to sales of Dermal
Tissue Augmentation Products in the Territory. Any additional payments required
as a result of such inspection and examination shall be immediately paid to
Biomatrix and shall bear interest from the date such amount would otherwise have
been paid until the date of actual payment at the rate per annum set forth in
Section 20. Such independent accounting firm shall conduct such inspections and
examinations under conditions of confidentiality.

for fewer than * units of the Agreement Product or the Improved Agreement
Product(s) (although multiple delivery site for purchase orders shall be

excess of the amounts in the then current Supply Forecast for the relevant
monthly period.

         (c)  Each unit of the Agreement Product and any Improved Agreement
Products shipped to the Distributor shall have, as of the time of delivery, a
remaining shelf life of no less than * less than the maximum shelf life for such
product, as approved by the U.S. Food and Drug Administration. Biomatrix shall
continually use its best efforts at all times during the term hereof to lengthen
to * the shelf life of the Agreement Product and any Improved Agreement Products

majority of three (3) arbitrators, one (1) of whom shall be appointed by each
party and the third of whom shall be appointed by mutual agreement of the two
(2) party-appointed arbitrators. In the event of failure of a party to appoint
an arbitrator within thirty (30) days after commencement of the arbitration
proceeding or in the event of failure of the two (2) party-appointed arbitrators
to agree upon the appointment of the third arbitrator within sixty (60) days
after commencement of the arbitration proceeding, such arbitrator shall be
appointed by the American Arbitration Association in accordance with the Rules.
The arbitrators shall apply the governing law set forth in this Section.
Judgment upon an award rendered by the arbitrators may be entered in any court
having jurisdiction thereof.

         (b)   Each of the parties hereto acknowledges and agrees that damages
will not be an adequate remedy for any material breach or violation of this
Agreement if such material breach or violation would cause immediate and
irreparable harm (an "Irreparable Breach"). Accordingly, notwithstanding the
provisions of Section 18(a) to the contrary, in the event of a threatened or
ongoing Irreparable Breach, each party hereto shall be entitled to seek, in any
state or federal court in the State of New York, equitable relief of a kind
appropriate in light of the nature of the ongoing threatened Irreparable Breach,
which relief may include, without limitation, specific performance or injunctive
relief; provided, however, that if the party bringing such action is
unsuccessful in obtaining the relief sought, the moving party shall pay the
non-moving party's reasonable costs, including attorney's fees, incurred in
connection with defending such action. Such remedies shall not be the parties'
exclusive remedies, but shall be in addition to all other remedies provided in
this Agreement.

         19.   SEVERABILITY. In the event that any provision of this Agreement
shall be held by a court of competent jurisdiction or by any governmental body
to be invalid or unenforceable, such provision shall be deemed severable and the
remaining parts and provisions of this Agreement shall remain in full force and
effect.

         20.   FORCE MAJEURE. Each of the parties shall be excused from the
performance of its obligations hereunder in the event such performance is
prevented by force majeure, and such excuse shall continue as long as the
condition constituting such force majeure continues. For the purpose of this
Agreement, force majeure is defined as contingencies beyond the reasonable
control of either party, including, without limitation, acts of God, judicial or
regulatory action, war, civil commotion, destruction of production facilities or
materials by fire, earthquake or storm and labor disturbances (whether or not
any such labor disturbance is within the power of the affected party to settle).

         21.   INTEREST. Any overdue amounts payable by either party hereunder
shall bear interest compounded monthly at the prime lending rate for Dollars
published from time to time in The Wall Street Journal plus * per annum, or, if
lower, the highest rate permissible by applicable law, from the due date until
the date of payment.

         22.   NO PARTNERSHIP OR AGENCY. This Agreement and the relations hereby
established by and between Biomatrix and the Distributor do not constitute a
partnership, joint venture, agency or contract of employment between them.

         23.   NOTICES. All communications in connection with this Agreement
shall be in writing and sent by postage prepaid first class mail, courier, or

notice shall be the date of its actual receipt.

         24.   SURVIVAL. The provisions of Sections 3.3, 3.6, 3.7, 3.8, 6.2,
9.1, 9.2, 9.3, 9.4 and 9.5 of this Agreement shall survive the termination or
expiration of this Agreement (as the case may be) and shall remain in full force
and effect. The provisions of this Agreement that do not survive termination or
expiration hereof (as the case may be) shall, nonetheless, be controlling on,
and shall be used in construing and interpreting the rights and obligations of
the parties hereto with regard to, any dispute, controversy or claim which may
arise under, out of, or in connection with this Agreement.

         25.   MISCELLANEOUS. This Agreement sets forth the entire agreement
between the parties with respect to the transactions and arrangements
contemplated hereby and supersedes all prior oral or written arrangements. This
Agreement may be modified or amended only by a written instrument executed and
delivered by both parties. None of the provisions of this Agreement shall be
deemed to have been waived by any act or acquiescence on the part of either
party except by an instrument in writing signed and delivered by the party
executing the waiver. This Agreement may be executed in several identical
counterparts, each of which shall be an original, but all of which constitute
one instrument, and in making proof of this Agreement it shall not be necessary
to produce or account for more than one such counterpart.
