ITEM 1.        BUSINESS

          Organogenesis Inc. (the "Company" or "Organogenesis") designs,
develops and manufactures innovative medical therapeutics using living human
cells and natural connective tissue components. The Company's cell therapies,
matrix scaffold, and other tissue engineered products are designed to promote
the establishment and growth of the human body's natural healing process by
promoting the growth of new tissues that maintain, restore or improve biological
function. The Company was organized as a Delaware corporation in 1985. Its
principal executive offices are located at 150 Dan Road, Canton, Massachusetts
02021, and its telephone number is (617) 575-0775.

CORE TECHNOLOGIES

          Organogenesis was the first company founded to develop and
commercialize therapies based on innovations in tissue engineering. Tissue
engineering is a relatively new discipline focused on developing specialized
biomaterials and cellular constructs to assist, repair, regenerate, or replace
diseased or damaged organs. An understanding of the biology of cells and the
structure and function of the extracellular matrix, and the critical
interactions between the two, is needed to fully exploit the potential of tissue
engineering. Because of this, Organogenesis continually strives to broaden,
develop, and utilize its expertise in cell and connective tissue sciences.

          CELL SCIENCE.  The ability to work with and manipulate cells is
central to fully realizing the potential of tissue engineering. Cells are the
building blocks of life. They make up the organs of the body, serving physical,
metabolic, and other specialized functions. Organogenesis' emphasis on the
significance of cell science to tissue engineering has led not only to
Graftskin/TM/, but also has provided valuable experience for the future in such
areas as:

         -  Cell sourcing                          -  Transplantation 
                                                        immunology
         -  Specialized culture systems and media  -  Cell delivery and
                                                       therapy design
         -  Human cell bank production             -  Cryopreservation of
             complex tissues
         -  Cell safety screening and functional 
             testing

          Organogenesis has established significant expertise in the areas of
cell biology, cryopreservation technology, and immunology.

          Cell Biology.  Organogenesis has significant expertise in the science
          -------------                                                        
of three-dimensional organotypic cell culture -- the ability to produce living
cultures of cells with the properties and functions typical of the organ from
which they were derived. For example, Graftskin/TM/ is a three-dimensional,
organotypic skin product. This and other models (cornea) have provided important
scientific findings on cell-to-cell interaction, cell and matrix interaction,
and extracellular matrix production.

          By employing its cell growth and organotypic culture technologies,
Organogenesis has gained important knowledge of cell regulatory mechanisms and
factors controlling cell growth and tissue formation which will be broadly
applicable to many cell types. This expertise in cell biology should enable
Organogenesis to expand further into other cell therapy product opportunities.

          Cryopreservation Technology.  Organogenesis also has a leadership
          -----------------------------                                    
position in the field of cryopreservation -  the ability to freeze complex
living cell systems and then restore them to original temperature without
significant loss of cell viability or functionality.  Organogenesis'
cryopreservation technology will facilitate worldwide distribution of
Graftskin/TM/.  It will also enable Organogenesis to fully exploit opportunities
in the cell therapy arena.  The Company is aggressively protecting all aspects
of its proprietary cryopreservation technology through a comprehensive patenting
program, and currently has four separate cryopreservation patents allowed or
pending in the U.S. alone.

          Immunology.  Immunology plays a critical role in tissue engineering
          ------------                                                       
both in determining the body's reaction to a biomaterial and assisting in the
transfer of human cells between individuals (allogeneic cells). Organogenesis
has a strong in-house immunology department which supports both safety
evaluation of its products and new product development.

          The ability to transplant cells from one individual to another is
particularly critical to the development and commercialization of "off-the-
shelf" tissues. For example, the cells used in Graftskin/TM/ are derived from
infant foreskin tissue that would normally be discarded. Using proprietary cell
culture technology, one postage stamp-sized piece of foreskin can yield
approximately four acres of Graftskin/TM/ tissue.

          Immunological screening of Graftskin/TM/ recipients also shows no
evidence of immune response to the cell types used, indicating that allogeneic
keratinocyte and fibroblast cells can be used safely and effectively. These
findings represent an important step for the clinical validation of the
Graftskin/TM/ technology. Such studies also provide critical evidence to support
the general concept of the immune compatibility of allogeneic cells and will
positively impact the future of cell therapy, transplantation, and other areas
of tissue engineering.

          To ensure it remains a leader in immunobiology, Organogenesis has
established relationships with opinion leaders in the field.  One of these is
its collaboration with Children's Hospital in Boston to further advance
understanding of graft acceptance.  This expertise positions Organogenesis well
to expand its leadership position in tissue equivalents, cell therapies, and
other areas of tissue engineering.

          CONNECTIVE TISSUE SCIENCES.  Recognizing the importance of the
extracellular matrix to cell growth and differentiation, the Connective Tissue
Sciences group was also established to develop cell- compatible collagen for the
living tissue equivalent program.

          Through this group, Organogenesis has developed proprietary technology
relating to the extracellular matrix, including technology enabling it to
produce an array of cell-compatible collagen products. Organogenesis' collagen
has been shown to support cell growth and interaction in two different types of
settings:

          o       When cells are added to Organogenesis' collagen during product
manufacturing, the collagen supports cell growth, differentiation and
interaction.  This allows Organogenesis to develop products such as living
tissue equivalents and other types of cell therapies.  Graftskin/TM/ is an
example of this use of Organogenesis' collagen.

          o       When used as an implant by itself, Organogenesis' collagen
helps foster and direct the ingrowth of the patient's cells and blood vessels.
Over time, the recipient's body gradually replaces the implant's collagen with
its own tissue to form a fully functional analog of the missing tissue using the
implant as a guide.

                                       3
<PAGE>
 
          Additionally, Organogenesis can produce cell-compatible collagen in a
range of forms suitable for a variety of tissue engineering applications. For
applications requiring strong, cell-compatible constructs, Organogenesis has
developed dense fibrillar collagen (DFC), which can be made in a variety of
forms, including sheets, tubes and threads. Possible uses of the DFC constructs
range from cell therapy applications, to use as a matrix scaffold for host cell
ingrowth and replacement, to being a component of a medical device or implant.

          Augmenting this flexibility, in October 1995, the Company was issued a
patent (U.S. patent No.5,460,962) on its proprietary method for cold chemical
sterilization.  This process enables Organogenesis to sterilize collagen while
maintaining its cell compatibility.  Also in 1995, Organogenesis was issued
patents in both Japan and pan-Europe relating to its manipulation of collagen
into different forms.

          Organogenesis is capitalizing on its connective tissue expertise
through a number of internal and external programs.

PRODUCTS

          The Company is using its cell science and connective tissue science
technologies and expertise in a number of areas including wound care, urology,
cardiovascular medicine, and general surgery.  It is also exploring additional
opportunities in the areas of plastic surgery, orthopedics, ophthalmalogy, and
oral cavity medicine.  The Company seeks to design, develop and manufacture
products, derived from proprietary technology and manufacturing processes, to be
used as treatments in these areas.

          CELL THERAPIES

          GRAFTSKIN/TM/
          ---------    

          The Company's most advanced product, Graftskin/TM/, is a Living Skin
Equivalent (LSE/TM/) for the treatment of skin wounds. These include wounds
traditionally treated with skin, such as burn wounds and wounds due to
dermatological surgery, as well as the broader market of wounds which would
benefit from a biologically active cell therapy, such as chronic wounds (e.g.
venous stasis ulcers, diabetic ulcers and decubitus ulcers).

          As is discussed under Item 7, Management's Discussion and Analysis, on
January 17, 1996, Organogenesis and Sandoz Ltd. jointly announced that Sandoz
has been granted exclusive worldwide marketing rights for Graftskin/TM/, while
Organogenesis has exclusive global manufacturing rights.  This agreement is
structured to leverage the potential of Graftskin/TM/ and the strength of Sandoz
to provide Organogenesis with two on-going revenue streams. Organogenesis will
receive royalties on all Graftskin/TM/ sales, benefiting from Sandoz's strong
sales and marketing capabilities and its support for new uses for Graftskin/TM/.
Additionally, Organogenesis will supply Sandoz's global requirements for
Graftskin/TM/ and receive payment for each unit, again capitalizing on Sandoz's
strength in marketing the product.  In addition, Organogenesis will receive from
Sandoz equity payments, research support payments and milestone payments
potentially totaling $37.5 million.

          Product Description.
          --------------------

          Graftskin/TM/ was developed to be a Living Skin Equivalent.  Like
human skin, Graftskin/TM/ has both an upper epidermal layer and a lower dermal
layer.  The dermal layer of Graftskin/TM/ is comprised of living human
fibroblasts - the most common cell type of the human dermis -  interacting in a
collagen matrix as they would in human skin.  The epidermal layer is comprised
of living human keratinocytes - the most common cell type of the human epidermis
- - that have organized themselves as 

                                       4
<PAGE>
 
they would in human skin. One structure formed by the keratinocytes is the outer
stratum corneum layer, the primary protective layer of skin. To achieve this
high level of organization, Graftskin/TM/ is made using patented three
dimensional cell culture technology (organotypic culture) which produces tissue
with properties reflective of the native organ. Graftskin/TM/ looks, feels and
handles like human skin.

          Like human skin, Graftskin/TM/ is multi-functional.  Its different
components - the stratum corneum, the keratinocytes, the fibroblasts, and the
collagen matrix - can affect the wound healing process in different, but
related, ways.  Most importantly, these components can interact synergistically
as they would in human skin.  Graftskin/TM/ interacts with the wound bed in a
way that provides flexibility of response and maximizes the chance for
successful healing.

          Regulatory and Clinical Status
          ------------------------------

          Regulatory Status.
          In 1995, the Company submitted to the United States Food and Drug
Administration ("FDA"), and the FDA accepted for filing, the Graftskin/TM/
Premarket Approval Application ("PMA") for use in the treatment of venous
ulcers.  The official filing date for this PMA was October 4, 1995. The basis
for this submission was the Graftskin/TM/ venous ulcer pivotal trial discussed
below.

          The FDA has granted expedited review status to this PMA, which means
it receives priority in review over other pending device regulatory
applications.  PMA applications under expedited review status are still subject
to all other controls and requirements applicable to PMAs in the standard review
process.

          There can be no assurance that the Company will obtain the approvals
needed to market Graftskin/TM/ or that Graftskin/TM/ will be successfully
commercialized.

          Chronic wounds
          Today, an estimated 4 million people in the U.S. alone suffer from
chronic wounds, including venous ulcers, diabetic ulcers and decubitus ulcers.
An estimated 900,000-1.5 million of these patients suffer from venous ulcers.
These are generally considered to be the most difficult to heal of the chronic
wounds, as they are associated with the greatest compromise of the patient's own
wound healing ability.  In the Graftskin/TM/ venous ulcer pivotal trial,
approximately half of the patients enrolled had their ulcer for a year or
longer, which is reflective of the venous ulcer patient population in the
community. The Graftskin/TM/ venous ulcer pivotal trial, conducted under an
Investigational Device Exemption ("IDE") Supplement from the FDA, was a
prospective, randomized, controlled multi-center study performed at fifteen
centers.  It is the largest study of this type ever to be presented on the
treatment of venous ulcers.  The IDE Supplement allowed the participation of up
to 300 patients in this clinical trial.  Patient enrollment in this study was
completed in 1994 with 293 patients, and the efficacy evaluation phase and data
analysis were completed in 1995.  The primary endpoints of this study were: (1)
frequency of 100% wound closure and (2) time to 100% wound closure.

          This study showed that Graftskin/TM/ achieved 100% wound closure in
more patients, and achieved it faster, than standard compression therapy, the
current standard of care.  Both of these primary endpoints were highly
statistically significant.  Graftskin/TM/ was found to be highly effective even
in difficult-to-heal ulcers, such as ulcers of extended duration and deep dermal
ulcers.  Graftskin/TM/ was also found to have an excellent safety profile, with
no sign of tissue rejection.

                                       5
<PAGE>
 
          Traditional wound healing products must rely on the patient's own
wound healing ability to try to close the wound.  In this study, Graftskin/TM/
was found to provide biologic wound closure, and was thus able to contribute
directly to the wound healing process.  This is believed to be why Graftskin/TM/
can heal wounds that have remained open for long periods of time.

          The Company is currently initiating a pivotal clinical trial to study
Graftskin/TM/ in the treatment of diabetic ulcers. Organogenesis also expects to
initiate a pivotal clinical trial to study Graftskin/TM/ on the treatment of
decubitus ulcers within the next twelve months.

          Burn Wounds.
          Another clinical indication for Graftskin/TM/ is for the use in the
treatment of burn wounds.  Each year, about 100,000 people in the U.S. alone are
hospitalized for the treatment of burns.

          The Company has completed the patient enrollment and efficacy
evaluation phase of this trial, and is currently doing safety follow-up and data
analysis. Over 75 patients were enrolled at six clinical centers.  Available
data from this study suggests that meshed Graftskin/TM/ placed over meshed
autograft may function as a skin replacement. Graftskin/TM/ may be able to
reduce the number of autograft procedures required - thus reducing
hospitalization costs - and improve cosmetic and functional properties of the
damaged areas.

          Dermatological Surgery.
          Graftskin/TM/ is also being developed for use in the treatment of
wounds created by dermatological surgery, such as for removal of skin cancers,
birthmarks and tattoos. These wounds are sometimes treated using the patient's
skin as a graft, necessitating a second wound site and thus increasing procedure
cost and morbidity. Approximately one million dermatological procedures are
performed annually on a global basis.

          The Company has completed enrollment for a pivotal trial in this
indication, involving more than 100 patients at eight centers throughout the
United States.  The efficacy and safety evaluation phase of this study has been
completed and the data are being analyzed.  While the data from this study is
currently being analyzed, interim results suggest that Graftskin/TM/ treatment
provides immediate closure, resurfacing of the wound with epithelium, rapid
healing and good cosmetic results.

          NEW CELL SYSTEMS
          ----------------

          To further leverage its cell therapy technologies, in early 1996
Organogenesis established a New Cell Systems group.  This group will define, and
then spearhead, the development of Organogenesis' next cell therapy products.
To head this group, Organogenesis is building a team which includes individuals
with expertise in the fields of living cell encapsulation and organ assist
devices - - skills which are highly complementary to Organogenesis' established
technological strengths (e.g. in cell culture, immunology, cryopreservation).

          CONNECTIVE TISSUE PRODUCTS

          Organogenesis is capitalizing on its connective tissue expertise
through a number of internal and external programs, including Matrix Scaffold
products, ECM Pharma/TM/, and Biomaterials.

                                       6
<PAGE>
 
          Matrix Scaffold Products
          ------------------------

          The cell compatibility and strength of Organogenesis' collagen
products make them well-suited for applications requiring an implant which can
serve not only the immediate physical function, but also can foster and direct
the ingrowth of host cells and blood vessels -- the process that enables the
host to form a fully functional replacement for the original tissue using the
implant as a scaffold. Currently, many surgical procedures require obtaining
patient tissue from elsewhere in the body (autologous material) for use as the
repair material (e.g., a graft or a patch). Harvesting autologous material
creates the need for an additional invasive procedure, thereby increasing
procedure cost, duration, and morbidity. Synthetic implants, primarily plastics,
have been developed by other companies to provide an "off-the-shelf"
alternative; however, synthetics are incapable of achieving host integration and
perform poorly in many applications.

          Organogenesis' cell-compatible collagen can be developed into "off-
the-shelf" implants which are intended to remodel into host tissue at least as
well as autologous material. Organogenesis has several "matrix scaffold" implant
products in development for the urological, cardiovascular medicine, and general
surgery market, and is also exploring additional opportunities in the plastic
surgery, ophthalmic and oral cavity (e.g. periodontal) markets.

          Urology Products

          Urinary Incontinence Products
          About 25 million women worldwide suffer from urinary incontinence, a
number which is increasing as the population ages.  Nearly fifteen percent of
these women have intrinsic sphincter deficiency. Current treatment for this
condition includes injecting material to support the sphincter.  One drawback to
the products available today is that they tend to disperse, limiting their
support of the sphincter.

          To address this need, Organogenesis is utilizing its expertise in
tissue engineering to design an injectable product intended to offer improved
performance.  The Company's product is being designed to provide retention of
position, so that it can provide the necessary support to the sphincter.  It is
also being designed to allow population by the patient's own cells, and the
gradual replacement of the Organogenesis collagen by collagen produced by the
patient's own cells.  Thus, the Company is designing its product to provide
permanence of benefit without permanence of product. Among the 25 million women
with urinary incontinence, for some the only option is surgery.  Currently about
100,000 surgical procedures are performed annually in the U.S. for this
condition. A major limitation of the current procedure is that it requires
harvesting autologous material -- patient fascia -- for use as a sling for the
bladder.   For these patients, the Company is also developing a bladder sling.
This would serve as an "off-the-shelf" alternative to use of autologous
material, thus reducing procedure cost and morbidity, and broadening its appeal
to both physicians and patients.

          Other
          To further strengthen its program in urology, Organogenesis has a
research relationship with faculty of Dartmouth Hitchcock Medical Center on
treatment options for common urological conditions. Therapies being explored
include not only matrix scaffold products, but also opportunities exploiting
Organogenesis' cell culture capabilities.

          Cardiovascular Products

          The Company is developing products for use in interventional
cardiovascular procedures, such as the procedures performed to reopen or bypass
small diameter arteries that have been narrowed by atherosclerosis.  An
estimated 5 million people in the U.S. alone have ischemic heart disease,
resulting in nearly 800,000 direct revascularization procedures per year.  The
two most common of these are coronary artery bypass grafting (CABG) and
percutaneous transluminal coronary angioplasty (PTCA).  Organogenesis is
developing Graftartery for use in CABG and other small diameter grafting
procedures, and stent coating technology for use in PTCA procedures.

          Graftartery
          Nearly 300,000 CABG procedures and 175,000 surgical revascularizations
for peripheral vascular disease are performed annually in the U.S. alone. An
average of 3.5 grafts are required per CABG procedure.

          Despite the size of this market and the number of major companies
which have tried to develop small diameter arterial grafts, the principal graft
material used for CABG remains patient (autologous) saphenous vein (ASV).  Use
of ASV creates a second wound site, with associated pain and complications.  It
also greatly increases the duration, and thus the cost, of the CABG procedure.
However, ASV offers a feature not obtainable with synthetics - the ability to
foster the ingrowth of patient cells and sustain a smooth, open juncture between
the graft and the neighboring blood vessel.

          To address this need, Organogenesis is developing Graftartery.
Graftartery is being engineered  to provide the flexibility, host-integration
and handling characteristics of ASV with the advantage of being off-the-shelf.
Graftartery has shown encouraging findings in preclinical studies, and its
development is continuing.

          Stent Coating
          In 1995, an estimated 460,000 PTCA procedures were performed to re-
open narrowed coronary arteries in the U.S. alone.  In this procedure, arteries
narrowed by atherosclerosis are re-opened by inflating a small balloon at the
point of narrowing.  While some patients are better treated with CABG than PTCA,
for many patients PTCA offers appropriate therapy and has the advantage over
CABG of being minimally invasive.  A prime disadvantage of PTCA is that,
historically, approximately 20-40% of arteries opened via PTCA re-narrow within
a year due to a process called restenosis.  To reduce the incidence of
restenosis, small structures (stents) are now available for insertion at the
point of the balloon inflation to help keep the artery open.  It has been
projected that stents will be used in half of PTCA procedures within the next
few years.  Stents reduce the incidence of restenosis by about 25-30%; thus, it
still remains a common problem post-PTCA.

          To address this need, Organogenesis is also developing a collagen-
coating for endovascular stents.  This coating could be applied by a stent
manufacturer to improve stent performance.  The ability of the Company's
collagen to foster the ingrowth of host cells is felt to provide an important
benefit  by helping to shield the stent from the artery wall, while also
providing a smooth flow surface for the blood stream.

          General Surgical Products

          The Company believes that the properties of Organogenesis' collagen
fits well with the surgical need for patches, fillers, supports, connectors and
replacements. The Company is currently developing a surgical repair patch for
use in soft tissue procedures.  These include use in the reinforcement of
weakened soft tissue, and in the repair of body wall defects such as those
associated with hernias, trauma and surgery.  There are over 600,000 hernia
repair procedures performed each year in the U.S. 

                                       8

alone, and over 400,000 procedures associated with opening the pericardial sack
surrounding the heart. Preliminary evaluation of the surgical repair patch has
shown that it integrated into the body and that "patched" surgically-created
defects healed in a manner which resulted in a mechanically stable body wall.

          Other

          Organogenesis' product development focus also includes plastic surgery
and orthopedic applications.  Therapeutic approaches in these applications
suggest benefit from Organogenesis technologies in cell science and in
connective tissue science, and may be cell-based, matrix scaffold-based, or both
technologies in combination. Through its collaborations with Schepens Eye
Research Institute and with Brigham and Women's Hospital, Organogenesis is also
exploring additional opportunities in the areas of ophthalmology and oral
medicine (e.g. periodontal and esophageal procedures), respectively.

          ECM Pharma/TM/
          ----------    
          In 1994, the Company established ECM Pharma/TM/ to conduct research on
the discovery and development of human therapeutics based on, or targeted to,
the extracellular matrix.  This matrix, which includes collagen, is the
biologically active complex surrounding the cells.

In 1995, ECM Pharma/TM/ licensed from Harvard University a compound which has
the potential to regulate the breakdown of extracellular matrix and thus to
modify tissue remodeling.  ECM Pharma/TM/ has also entered into a research
collaboration with Harvard Medical School related to the discovery of
extracellular matrix-related therapeutics.  One such program relates to keloids,
a condition characterized by abnormal scarring in response to injury.  This
condition can cause considerable cosmetic and symptomatic problems in young
adults, particularly in non-white populations.

          Biomaterials
          ------------
          Based on interest expressed in its collagen, in 1994 Organogenesis
established a Biomaterials division, and is now selling its cell-compatible
collagen to industrial and academic researchers through a laboratory supply
business.  Future revenues from this business line are not expected to be
significant.

COMPETITION

          The Company is engaged in the rapidly evolving and competitive field
of tissue engineering. Many major pharmaceutical, biotechnology and medical
product companies in the United States and abroad are seeking to develop
competitive products for the treatment of skin wounds and organ equivalent
products. Competition from these companies and others is intense and is expected
to increase. Many of these companies have substantially greater capital
resources, research and development staffs and facilities and experience in the
marketing and distribution of products than the Company. In addition,
competitive companies are working on alternate approaches to many of the
diseases targeted by the Company.

          The Company is currently aware of other companies which have or are
planning to commercialize products intended to serve as skin replacements, in
addition to several companies that concentrate on skin repair devices. The
Company's principal competitors in the wound care products market include
Johnson & Johnson, Kendall, Smith & Nephew, Advanced Tissue Sciences, Bristol-
Myers Squibb and Genzyme Tissue Repair. The Company believes that its
competitive position will be based on its ability to create and maintain
scientifically advanced technology and proprietary products and processes,
attract and retain qualified scientific personnel, obtain patent or other
protection for its products and processes, obtain required government approvals
on a timely basis, manufacture its products on a cost-effective basis and
successfully market its products.

                                       9
<PAGE>
 
RETENTION OF KEY PERSONNEL

          Because of the specialized nature of the Company's business, the
Company's success will depend, in large part, on its continued ability to
attract and retain highly qualified scientific and business personnel and on its
ability to develop and maintain relationships with leading research
institutions. The competition for those relationships and for experienced
scientists and management personnel that exists among the numerous
biotechnology, pharmaceutical and healthcare companies, universities and
nonprofit research institutions is intense.

PATENTS AND PROPRIETARY TECHNOLOGY

          Organogenesis has a proprietary portfolio of patent rights and
applications, and exclusive licenses to patents and patent applications relating
to tissue equivalents, cell therapies, and other aspects of tissue engineering.
These patent applications include patents relating to tissue sourcing, methods
of preparation, cell culture technologies, sterilization technologies,
manufacturing methods, and cryopreservation of living tissue.  The Company
intends to continue to attempt to aggressively patent its technologies.

          In the U.S. alone, the Company has twelve issued patents plus two
patents which have reached notice of allowance status.  The Company also has six
pan-European patents issued plus one which has achieved intent to grant status,
while in Asia the Company has eight issued patents plus one patent which has
achieved notice of allowance status.

          Some of the Company's technologies are licensed under an exclusive
patent license agreement with the Massachusetts Institute of Technology ("MIT").
The agreement with MIT (as amended, the "MIT Agreement") covers certain U.S.
patents and corresponding patents in European and Far East countries. Pursuant
to the MIT Agreement, the Company has been granted an exclusive, worldwide
license to make, use and sell the products covered by the patents and to
practice the procedures covered by the patents. The MIT Agreement requires the
Company to pay to MIT a royalty on the cumulative net sales of licensed products
ranging from 3% to 4.5% of annual sales.

          The Company's other U.S. issued patents relate to: the Company's test
system incorporating skin tissue equivalents and other organ equivalents; its
proprietary collagen extraction process;  the invention and methods of making
DFC constructs; the production of an organ equivalent for the cornea and its
method of production using tissue culturing systems; a method of making collagen
thread; and a method of cold chemical sterilization which maintains the cell-
compatibility of the Company's collagen. As part of the continuing interest in
protecting its intellectual property rights, the Company has also filed, and is
prosecuting, over ten other patent applications in the United States alone.  The
Company also aggressively attempts to achieve comparable patents in the major
international markets for its products, particularly in Europe and Japan.

          There can be no assurance that any patents will be issued as a result
of the Company's patent applications, or that issued patents will provide the
Company with significant protection against competitors. Moreover, there can be
no assurance that any patents issued to or licensed by the Company will not be
infringed, or that third parties will not independently develop either the same
or similar technology.

          A portion of the Company's know-how and technology are trade secrets.
To protect its rights, the Company requires key employees and consultants to
maintain the confidentiality of the Company's proprietary information, and the
Company intends to require any corporate sponsor with which the Company enters
into collaborative research and development agreement to do so as well. There
can be 

                                       10
<PAGE>
 
no assurance, however, that these agreements will provide meaningful protection
for the Company's trade secrets, know-how or other proprietary information in 
the event of any unauthorized use or disclosure.

GOVERNMENT REGULATION

          The Company's present and proposed activities are subject to
government regulation in the United States and other countries. In order to
clinically test, produce and market medical devices for human use, the Company
must satisfy mandatory procedures and safety and efficacy requirements
established by the FDA and comparable state and foreign regulatory agencies.
Typically, such rules require that products be approved by the government agency
as safe and effective for their intended use prior to being marketed. The
approval process is expensive, time-consuming and subject to unanticipated
delays, and no assurance can be given that any agency will grant its approval.

          Testing is necessary to determine safety and efficacy before a
submission may be filed with the FDA to obtain authorization to market regulated
products. In addition, the FDA imposes various requirements on manufacturers and
sellers of products under its jurisdiction, such as labeling, good manufacturing
practices, record keeping and reporting requirements. The FDA also may require
post-marketing testing and surveillance programs to monitor a product's effects.

          As the Company develops products to the point where FDA authorization
becomes required, there can be no assurance that the appropriate authorization
will be granted, that the process to obtain such authorization will not be
excessively expensive or lengthy, or that the Company will have sufficient funds
to pursue such approvals. Moreover, the failure to receive requisite
authorization for the Company's products or processes, when and if developed, or
significant delays in obtaining such authorization, would prevent the Company
from commercializing its products as anticipated and may have a materially
adverse effect on the business of the Company.

          The regulatory status of Graftskin/TM/ is as follows: In 1989, the FDA
granted the Company an IDE for clinical testing of Graftskin/TM/ on burn
patients. In 1992, the FDA granted the Company IDE Supplements for clinical
testing of Graftskin/TM/ for the treatment of chronic skin ulcers and clean
excision wounds.  In late March 1995, the Company held its pre-PMA meeting with
the FDA.  The Graftskin/TM/ venous ulcer PMA was later submitted, and has been
officially filed by the FDA with a filing date of October 4, 1995.  The FDA has
granted expedited review status to this PMA, which means it receives priority
review over other pending device regulatory applications.

PRODUCT LIABILITY AND AVAILABILITY OF INSURANCE

          The Company's business exposes it to potential liability risks that
are inherent in the testing, manufacturing and marketing of medical products.
The use of the Company's product candidates in clinical trials may expose the
Company to product liability claims and possible adverse publicity. These risks
also exist with respect to the Company's product candidate, if any, that receive
regulatory approval for commercial sale. The Company currently has limited
product liability coverage for the clinical research use of its product
candidates. The Company does not have product liability insurance for the
commercial sale of its product candidates but intends to obtain such coverage if
and when its products are commercialized. However, there can be no assurance
that the Company will be able to obtain additional insurance coverage at
acceptable costs, if at all, or that a product liability claim would not
materially have an adverse affect on the business or financial condition of the
Company.

MANUFACTURING AND SOURCES OF SUPPLY

          The Company manufactures Graftskin/TM/ for use in its clinical trials
at its Canton, Massachusetts facility and intends to manufacture Graftskin/TM/
for commercial sale at the facility. See "Item 2 -- PROPERTIES."

          Among the fundamental raw materials needed to fabricate Graftskin/TM/
is a small number of keratinocyte and fibroblast cells. In order for products of
the Company made with these initial cells to be used as a replacement for human
skin, it is critical that the cells be disease-free. The Company has experienced
no difficulty obtaining cells, and has established a mechanism for obtaining
screened cells from donors certified by blood testing to be free of the HIV or
"AIDS" virus and other pathogens.

          The major additional material required to produce the Company's
products is collagen, a protein ordinarily obtained from cows or pigs by
commercial suppliers. The Company determined that the collagen provided by the
usual commercial sources is not suitable for the Company's purposes.
Accordingly, the Company has developed a proprietary method of producing its own
collagen. This process yields collagen which the Company believes is superior in
quality and strength to collagen available from commercial sources and which
provides the Company with a continuous, high-quality source of supply.

          The other raw materials required in the production of the Company's
products are primarily chemical nutrients, which are readily available from a
number of commercial sources.

COLLABORATIVE AGREEMENTS

          In July 1993, the Company announced its collaboration with Eli Lilly
and Company ("Lilly") to develop, manufacture and market Graftartery, a product
intended for use as a replacement for human arteries, had ended. The Company
intends to complete the development effort of the Graftartery project either
with its own funds or through a potential collaboration with another party.

          In July 1993, the Company entered into a research agreement with
Biomet, Inc. ("Biomet") for the development of orthopedic implants using the
Company's proprietary dense fibrillar collagen. The Company and Biomet have
mutually agreed to change the research agreement to a supply arrangement under
which the Company will provide Biomet with Collagen.

RESEARCH AND OTHER AGREEMENTS

          In March 1995, ECM Pharma/TM/ signed a research agreement, with an
option to negotiate a license, with Harvard Medical School to supplement
research related to the discovery of extracellular matrix-related therapeutics.

          In December 1995, the Company signed a research agreement with the
Brigham and Women's Hospital to focus on additional opportunities in the areas
of oral medicine (specifically esophageal procedures).

          In 1995, the Company agreed to fund certain work performed at the
Connective Tissue Research Laboratory at Hebrew University. The Company would
negotiate any additional terms if this research leads to a product.

          The Company also has agreements with thirty-one clinical sites, to
conduct human clinical trials of Graftskin/TM/. Clinical trials are used to test
Graftskin/TM/ safety and effectiveness as a treatment for chronic ulcers, wounds
resulting from dermatological surgery and burns.

RESEARCH AND DEVELOPMENT

          The Company plans to continue to focus its product development effort
on developing high quality cell therapy , matrix scaffold, and other types of
tissue engineered products in such areas as wound care, urology, cardiovascular
medicine, and general surgery.

          The Company's research and development staff consists of scientists
and laboratory assistants with technical backgrounds in cell biology, matrix
biology, cell culture, immunology, cryopreservation, molecular biology and
clinical medicine.

          For 1995, 1994 and 1993, the Company's research and development
expenses were $9,679,000, $8,573,000, and $8,117,000, respectively.

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

MANAGEMENT'S DISCUSSION AND ANALYSIS

The following discussion contains forward-looking statements which involve risks
and uncertainties. The Company's actual results may differ significantly from
the results discussed in the forward-looking statements. Factors that might
cause such a difference include, but are not limited to, those discussed under
"Liquidity and Capital Resources".

Results of Operations

1995 Compared to 1994

  Contract revenues during 1995 were $19,000, compared to $336,000 in 1994. The
contract revenue was realized by the Company under a research agreement with
Biomet, Inc. ("Biomet") for the development of orthopedic implants using the
Company's proprietary dense fibrillar collagen. The Company and Biomet have
mutually agreed to replace the research agreement with a supply arrangement
under which the Company will sell collagen to Biomet. Interest income in 1995
was $608,000, compared to $660,000 in 1994.

  Research and development expenses increased to $9,679,000 from $8,573,000 in
1994. The increase was primarily due to the Company's regulatory filing and
preparation for commercialization of Graftskin/TM/ and related increases in
resources in clinical research, cryobiology, quality assurance, and process
scale-up.  The increase was also due in part to the Company establishing
research collaborations with leading academic institutions, including Harvard
Medical School and Hebrew University, to further enhance its product portfolio.
General and administrative expenses increased to $3,685,000 in 1995 from
$2,865,000 in 1994, primarily due to higher legal, consulting and other
professional services resulting mainly from the 1995 public offering, the
collaborative agreement with Sandoz, and supporting the activity in research and
development. The Company's net loss for 1995 was $12,737,000, or $1.02 per
share, as compared with a net loss for 1994 of $10,441,000, or $.91 per share.

1994 Compared to 1993

  Contract revenues during 1994 were $336,000, compared to $375,000 in 1993.
Contract revenues in 1994 were realized by the Company under an agreement with
Biomet for the development of orthopedic implants using the Company's
proprietary dense fibrillar collagen. Contract revenues in 1993 were realized
under agreements with Eli Lilly and Company ("Lilly") relating to the
development of the Company's Graftartery product and with Biomet. The Company's
collaboration with Lilly ended in July 1993. No sale of product occurred in
1994, as compared to $72,000 in 1993. This was due to the Company's
discontinuance of the manufacturing and selling of its Testskin products.
Interest income in 1994 was $660,000 compared to $1,146,000 in 1993. The
decrease in 1994 resulted from less cash available for investment.

  Research and development expenses increased to $8,573,000 from $8,117,000 in
1993. The increase was primarily due to higher employment-related costs
resulting from staff additions and data management and statistical services
related to human clinical trials for Graftskin/TM/.  General and administrative
expenses decreased to $2,865,000 in 1994 from $3,347,000 in 1993, primarily as a
result of lower outside services rendered to the Company. The Company's net loss
for 1994 was $10,441,000, or $.91 per share, as compared with a net loss for
1993 of $9,936,000, or $.87 per share.

Liquidity and Capital Resources

  From inception, the Company has financed its operations substantially through
private and public placements of equity securities, as well as receipt of
contract revenues,  interest income from investments and, to a lesser extent,
sale of products. At December 31, 1995 and 1994, respectively, the Company had
cash, cash equivalents and investments in the aggregate of $13,721,000 and
$8,871,000. The increase was primarily due to the completion of a public
offering in July 1995 in which the Company received net proceeds of $14,773,000
from the sale of 1,150,000 shares of Common Stock and 230,000 Unit Warrants.

  In January 1996, the Company and Sandoz Ltd. ("Sandoz") entered into an
agreement that grants Sandoz exclusive worldwide marketing rights to
Graftskin/TM/.  The Company  will supply Sandoz's global requirements for the
product and receive payment for each unit.  The Company will also receive
royalty revenues on all  Graftskin/TM/ sales.  In addition, Sandoz will provide
the Company with up to $37,500,000 in equity investments, milestone payments,
and research support payments, including an initial $5,000,000 equity investment
at $23.37 per share and additional equity investments of $10,500,000 upon
achievement of specified milestones. Subsequent to December 31, 1995, the
Company received proceeds from Sandoz of $5,000,000 representing the first
equity investment in the Company and $4,000,000 representing the first
contribution to the Company's research and development costs for Graftskin/TM/.
As a result of this initial equity investment, Sandoz holds approximately 1.6%
of the outstanding shares of Organogenesis.

  The Company will continue to utilize working capital in 1996 related to
ongoing product research and development activities, conducting preclinical and
clinical trials, enhancement of proprietary manufacturing technologies and
expansion of business development, general and administrative resources. These
activities will require substantial additional financial resources before the
Company can expect to realize revenue from product sales. While management
believes that additional financing composed of equity investments and funding
provided under collaborative agreements will be available to fund future
operations, and are being pursued, there can be no assurances that additional
funds will be available when required on terms acceptable to the Company.

  Based upon its current plans, the Company believes that the future equity and
research contributions from Sandoz, together with existing working capital, will
be sufficient to fund its operations at least through the second quarter of
1997.  However, the Company's capital requirements may vary depending on
numerous factors, including: progress of the Company's research and development
programs; time required to obtain regulatory approvals; resources the Company
devotes to self-funded projects, proprietary manufacturing methods and advanced
technologies; and the demand for the Company's products, if and when, approved.

  The Company is subject to risks common to companies in the biotechnology
industry including, but not limited to, development by the Company or its
competitors of new technological innovations, risks of failure of clinical
trials, dependence on key personnel, protection of proprietary technology,
compliance with United States Food and Drug Administration regulations and
ability to transition from pilot-scale manufacturing to large-scale production
of products.

  In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123), which is effective for transactions entered into in
fiscal years that begin after December 15, 1995.  SFAS 123 establishes a fair
value based method of accounting for stock-based compensation plans.  The
Company plans to adopt the disclosure method in 1996. The Company has not
determined the effect on a proforma basis to 1995 net income and earnings per
share, of applying fair value accounting rules to grants of stock-based awards
in 1995.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Organogenesis Inc.:

  We have audited the accompanying consolidated balance sheets of Organogenesis
Inc. and its wholly owned subsidiaries as of December 31, 1995 and 1994, and the
related consolidated statements of operations, cash flows, and changes in
stockholders' equity for each of the three years in the period ended December
31, 1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Organogenesis Inc.
and its wholly owned subsidiaries as of December 31, 1995 and 1994, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ORGANOGENESIS INC.

Nature of Business:

  Organogenesis Inc. (the "Company") designs, develops and manufactures
innovative medical therapeutics using living human cells and natural connective
tissue components. The Company's cell therapies, matrix scaffold and other
tissue engineered products are designed to promote the establishment and growth
of the human body's natural healing process by promoting the growth of new
tissues that maintain, restore or improve biological function.

  The Company has formed a wholly owned subsidiary, ECM Pharma/TM/, Inc. ("ECM
Pharma/TM/"). ECM Pharma/TM/ was established to discover, develop and
commercialize human therapeutics based on the extracellular matrix. The Company
has also formed a wholly owned investment subsidiary, Dan Capital Corporation,
which holds a substantial portion of the Company's cash, cash equivalents and
investments.

  The ultimate success of the Company is dependent upon its ability to raise
capital through equity placement, royalty and manufacturing payments, receipt of
contract revenue, sale of product, research and development funding under
licensing agreements and interest income on invested capital. However, the
Company's capital requirements may change depending upon numerous factors,
including progress of the Company's research and development programs; time
required to obtain regulatory approvals; resources the Company devotes to self-
funded projects, proprietary manufacturing methods and advanced technologies;
and the demand for the Company's products, if and when, approved.

  While management believes that additional financing composed of equity
investments and funding provided under collaborative agreements will be
available to fund future operations, and are being pursued, there can be no
assurances that additional funds will be available when required on terms
acceptable to the Company.

  The Company is subject to risks common to companies in the biotechnology
industry including, but not limited to, development by the Company or its
competitors of new technological innovations, risks of failure of clinical
trials, dependence on key personnel, protection of proprietary technology,
compliance with United States Food and Drug Administration regulations and
ability to transition from pilot-scale manufacturing to large-scale production
of products.
 .
Summary of Significant Accounting Policies:

 Principles of Consolidation

  The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All intercompany activity has been eliminated.

 Use of Estimates

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

                                       25
<PAGE>
 
 Revenue Recognition

  Contract revenues under research and development agreements are recognized as
the related efforts are performed. Product sales are recognized as products are
shipped. Deferred revenue arises from differences between cash received and
revenue recognized under the research and development agreement.

 Research and Development Costs

  All research and development costs are expensed as incurred.

 Income Taxes

  Research and development and other tax credits are recognized for financial
reporting purposes when they are realized. Deferred taxes are determined based
on the difference between the financial reporting and the tax bases of assets
and liabilities using enacted income tax rates in effect in the years in which
the differences are expected to reverse. Tax credits will be recorded as a
reduction in income taxes when utilized.

 Net Loss Per Common Share

  Net loss per common share is based on the weighted average number of common
shares outstanding during each period. Common share equivalents have not been
included because the effect would be antidilutive.

 Cash and Cash Equivalents

  Cash and cash equivalents consists of cash and money market funds, which are
convertible into a known amount of cash and carry an insignificant risk of
change in value.

 Property and Equipment

  Equipment, furniture and fixtures and leasehold improvements are stated at
cost. Depreciation is provided using the straight-line method over five to ten
years. Leasehold improvements are being amortized using the straight-line method
over the term of the lease.

  Maintenance and repairs are charged to expense as incurred and betterments are
capitalized. Upon retirement or sale, the cost of assets disposed of and their
related accumulated depreciation are removed from the accounts. Any resulting
gain or loss is credited or charged to operations.

 New Accounting Pronouncement

  In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123), which is effective for transactions entered into in
fiscal years that begin after December 15, 1995.  SFAS 123 established a fair
value based method of accounting for stock-based compensation plans.  The
Company plans to adopt the disclosure method in 1996.  The Company has not
determined its effect on a proforma basis to 1995 net income and earnings per
share of applying fair value accounting rules to grants of stock-based awards in
1995.

Income Taxes:

  The Company has made no provision for income taxes due to its continued
operating losses. The Company has a net operating loss tax carryforward of
approximately $64,000,000, and research and development tax credits of
approximately $2,200,000, expiring at various dates through 2009. Ownership
changes may result in future limitations on the utilization of net operating
losses and research and development tax credit carryforwards.

  The approximate tax effect of each type of temporary difference and
carryforward is reflected in the following table. The effective tax rate is
expected to be 40% combined federal and state.

1995.  There were 13,732,437 and 11,707,748 shares of Common Stock issued and

  In November 1991, the Company completed a public offering of 1,650,000 shares
of its Common Stock. This offering resulted in the Company receiving net
proceeds of $36,144,336. In connection with this offering, the underwriter was
issued a warrant to purchase 187,500 shares of Common Stock, exercisable at any
time during a four-year period, at a per share price of $10.60 (adjusted for the
dilution provisions in the warrant).

  In April 1991, the Company received net proceeds of $924,017 from the sale of
125,000 shares of Common Stock, and warrants to purchase Common Stock
exercisable at any time during a five-year period. The warrants allow for the
purchase of 31,250 shares of Common Stock at $9.60 per share and 15,625 shares
at $12.00 per share.

Stockholder Rights Plan:

  In August 1995, the Board of Directors adopted a Stockholder Rights Plan and
declared a dividend of one Right for each outstanding share of Common Stock to
stockholders of record on September 1, 1995.  Each Right only becomes
exercisable and transferable apart from the Common Stock, at the earlier of (i)
10 days after a person or group acquires beneficial ownership of 15% or more of
the Company's outstanding Common Stock (the "Stock Acquisition Date") or (ii) 10
business days following an announcement of a tender or exchange offer of 30% or
more of the Company's outstanding stock.

  Initially, each Right, upon becoming exercisable, would entitle the holder to
purchase one-thousandth of a share of Series B Junior Participating Preferred
Stock at an exercise price of $85, subject to adjustment.  If a person or group
acquires beneficial ownership of 15% or more of the outstanding shares of Common
Stock, then each holder of a Right (other than Rights held by the acquiring
person or group) would have the right to receive that number of shares of Common
Stock which equals the exercise price of the Right divided by one-half of the
current market price of the Common Stock.

  The Rights may be redeemed by the Company for $0.01 per Right at any time
until the tenth day following the stock acquisition date.  The Rights will
expire on September 1, 2005.

Stock Options:

  The Company has reserved an aggregate of 2,500,000 shares of Common Stock for
issuance under its 1986 Stock Option Plan (the "1986 Plan"). The 1986 Plan was
established to provide for the granting of incentive and non-qualified stock
options to enable the Company to attract and retain key employees and
consultants. The 1986 Plan is administered by the Board of Directors or its
delegated Committee which selects the recipients of options and determines (i)
the type of option to be granted, (ii) the number of shares included in each
option, (iii) when the option becomes exercisable or, if the option is
immediately exercisable, the Company's repurchase rights with respect to shares
purchased upon the exercise of the option, (iv) the exercise price, which cannot
be less than the fair market value of the Company's stock on the date of grant
in the case of incentive stock options or less than 90% of the fair market value
of the Company's stock on the date of grant in the case of the non-qualified
stock options, and (v) the duration of the option, which cannot exceed ten years
for incentive stock options or ten years and thirty days for non-qualified
options. Vesting occurs over a five-year period beginning one year from the date
of grant. Activity under the 1986 Plan is summarized as follows:

the "1995 Plan") providing for the issuance of up to 1,500,000 shares of Common

         The Corporation hereby represents and warrants to the Investor as

         3.1. Organization. The Corporation and each of its wholly-owned

subsidiaries (each a "Subsidiary" and, collectively, the "Subsidiaries") is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has all requisite corporate power and authority to
own and lease its property and to carry on its business as presently conducted.
The Corporation and each of the Subsidiaries is duly qualified to do business as
a foreign corporation in the Commonwealth of Massachusetts. Neither the
Corporation nor any Subsidiary owns or leases property or engages in any
activity in any other jurisdiction which would require its qualification in such
jurisdiction and in which the failure to be so qualified would have an adverse
effect on the financial or any other business condition of the Corporation or
the Subsidiary, as the case may be.

         3.2. Capitalization.

          Corporation or any Subsidiary.

         (b) The financial statements described in Section 3.6(i), including any
notes thereto, reflect all material liabilities of the Corporation and the
Subsidiaries as of the date of such financial statements required to be
reflected thereon in accordance with generally accepted accounting principles.
Since the date of such financial statements, the Corporation and the

obligations, agreements and conditions contained in any evidence of indebtedness
or any loan agreement or other contract or agreement (whether or not relating to
indebtedness) to which the Corporation or any Subsidiary is a party or is
subject (collectively, the "Obligations") , the lack of compliance with which
could afford to any person the right to accelerate any indebtedness or terminate
any right or agreement of the Corporation or any Subsidiary. To the best of the
Corporation's knowledge and belief, all other parties to such Obligations are in
compliance with the terms and conditions of such Obligations.

         (e) Each current employee of or consultant to the Corporation or any
Subsidiary who has or is proposed to have access to confidential or proprietary

judgment, order, writ or decree to which it is a party or by which it is bound,
and neither the Corporation nor any Subsidiary is in violation of any provision
of any federal or state statute, rule or regulation applicable to the
Corporation or any Subsidiary, which violation would have a material adverse
effect on the business of the Corporation and the Subsidiaries, taken as a
whole.

         (i) Included in Schedule 3.6(i) attached hereto are the following
consolidated financial statements of the Corporation and the Subsidiaries, all
of which have been prepared in accordance with generally accepted accounting
principles consistently applied and fairly present the consolidated financial
position of the Corporation and the Subsidiaries as of the dates of such
financial statements and the results of its operations and cash flows for the
periods covered thereby, subject only to the matters described in the
accountant's report attached thereto:

               (i) Consolidated Balance Sheet dated December 31, 1994 and
          Consolidated Statements of Operation, Stockholders' Equity and Cash
          Flows for the year ended December 31, 1994, certified by Coopers and
          Lybrand L.L.P., independent public accountant to the Corporation; and

               (ii) Unaudited Consolidated Balance Sheet as of September 30,
          1995, and Consolidated Statements of Operation and Cash Flows for the
          period from January 1, 1995 through September 30, 1995 (the "Unaudited
          Financial Statements") . The Unaudited Financial Statements are
          complete and correct, are in accordance with the books and records of
          the Corporation and the Subsidiaries and present fairly, in all
          material respects, the consolidated financial condition and results of
          operations and cash flows of the Corporation and the Subsidiaries, as
          at the dates and for the periods indicated, and have been prepared in
          accordance with generally accepted accounting principles consistently
          applied, except that the Unaudited Financial Statements have been
          prepared for the internal use of management and may not be in
          accordance with generally accepted accounting principles because of
          the absence of footnotes normally contained therein and are subject to
          normal year-end audit adjustments which in the aggregate will not be
          material.

         (j) Since December 31, 1994, the Corporation and the Subsidiaries have
conducted their respective businesses in the ordinary course, and there has not
been any material adverse change in the financial condition or operations of the

Exchange Commission. Asterisks denote omissions.


franchise tax returns, real estate and personal property tax returns, sales and
use tax returns, payroll tax returns and other tax returns required to be filed
by it and the Subsidiaries, and has paid or made provision for the payment of
all accrued and unpaid taxes and other charges to which the Corporation is
subject and which are not currently due and payable. The federal income tax
returns of the Corporation have never been audited by the Internal Revenue
Service. Neither the Internal Revenue Service nor any other taxing authority is
now asserting nor is threatening to assert against the Corporation any
deficiency or claim for additional taxes or interest thereon or penalties in
connection therewith, and the Corporation does not know of any such deficiency
or basis for such a deficiency or claim.

         3.8. Securities Laws.

securities of the Corporation for sale to, or solicited any offers to buy the
same from, or sold securities of the Corporation to, any person or organization,
in any case so as to subject the Corporation, its promoters, directors or
officers to any liability under the Securities Act, the Securities Exchange Act
of 1934, as amended, or any state securities or "blue sky" law (collectively,

         The Corporation and each Subsidiary has good, legal and merchantable
title to all of its assets, including all properties and assets reflected on the
December 31, 1994 Consolidated Balance Sheet, free and clear of all liens,
claims, restrictions or encumbrances, except those assets disposed of since the
date of such Balance Sheet in the ordinary course of business, none of which
either alone or in the aggregate are material, either in nature or amount, to
the business of the Corporation and the Subsidiaries taken as a whole. All
machinery and equipment included in such properties which are material to the
business of the Corporation and the Subsidiaries taken as a whole are in good
condition and repair, and each lease of real or personal property to which the
Corporation is a party is fully effective, affords the Corporation or the
Subsidiary, as the case may be, peaceful and undisturbed possession of the
subject matter of the lease, and such lease is free of any liens, claims,
restrictions or encumbrances. Each such lease constitutes a valid and binding
obligation of, and is enforceable in accordance with its terms against, the
respective parties thereto. The Corporation or the Subsidiary, as the case may
be, has in all respects performed the obligations required to be performed by it
to date under such leases and is not in default thereunder in any respect, and
there has not occurred any event which (whether with or without the passage of
time or the giving of

entity which is outstanding on the date hereof, nor is it committed or obligated
to make any such loan or advance, and (b) neither the Corporation nor any
Subsidiary has owned or controlled and does not currently own or control,
directly or indirectly, any subsidiaries and has never owned or controlled and
does not currently own or control any capital stock or other ownership interest,
directly or indirectly, in any corporation, association, partnership, trust,
joint venture or other entity.

         3.11. ERISA.
               -----

         Except as disclosed in Schedule 3.11 attached hereto, neither the
Corporation nor any Subsidiary has made, nor been required by law or contract to
make, contributions to any pension, defined benefit or defined contribution
plans for its employees which are subject to the Federal Employee Retirement
Income Security Act of 1974, as amended.

         3.12. Licenses and Other Rights; Compliance with Laws.
               -----------------------------------------------

         The Corporation and the Subsidiaries have all franchises, permits,
licenses and other rights and privileges necessary to permit them to own their
respective properties and to conduct business as presently conducted. The
Corporation or the Subsidiary, as the case may be, is in compliance in all
material respects under each, and the transactions contemplated by this
Agreement will not cause a violation under any of such franchises, permits,
licenses and other rights and privileges. The Corporation and the Subsidiaries
are in compliance in all material respects with all laws and governmental rules
and regulations applicable to their respective businesses, properties and
assets, and to the products and services sold by it, including, without
limitation, all such rules, laws and regulations relating to fair employment
practices and public or employee safety. The Corporation and the Subsidiaries
are in compliance with the applicable provisions of the Clinical Laboratories
Improvement Act of 1967, as amended.

         3.13. Board of Directors.
               ------------------
         Except as provided in Section 6(b) (i), the Corporation has not
extended any offer or promise or entered into any agreement, arrangement,
understanding or otherwise, whether written or oral, with any person or entity
by which the Corporation has agreed to allow such person or entity to
participate, in any way, in the affairs of the Board of Directors of the
Corporation, including without limitation, appointment or nomination as a

duties, responsibilities (for cleanup, remedy or otherwise) or liabilities under

have such duties, responsibilities or liabilities because of past acts or
omissions of the Corporation or any Subsidiary or their predecessors, or because
the Corporation or any Subsidiary or their predecessors in the past was such an
owner or operator of, or bore some other relationship with, such land, buildings
or laboratory facilities, all as more fully described in Schedule 3.14(a)
attached hereto. The term "Hazardous Materials" shall include without
limitation, any flammable explosives, petroleum products, petroleum by-products,
radioactive materials, hazardous wastes, hazardous substances, toxic substances

         (b) Neither the Corporation nor any Subsidiary has received written
notice that the Corporation or any Subsidiary is a party potentially responsible
for costs incurred at a cleanup site or corrective action under any
Environmental Laws. Neither the Corporation nor any Subsidiary has received any
written requests for information in connection with any inquiry by any
Governmental Authority (as hereinafter defined) concerning disposal sites or
other environmental matters. As used herein, "Governmental Authority" shall mean
any nation or government, any federal, state, municipal, local, provincial,
regional or other political subdivision thereof, and any entity or person
exercising executive, legislative, judicial, regulatory or administrative
functions of, or pertaining to, government. As used herein, "Environmental Laws"

         3.15. Reliance; "Knowledge".
               ---------------------

         The Corporation understands that the foregoing representations and
warranties shall be deemed material and to have been relied upon by the
Investor. No representation or warranty by the Corporation in this Agreement,
and no written statement contained in any document, certificate or other writing
delivered by the Corporation to the Investor contains any untrue statement of
material fact or omits to state any material fact necessary to make the
statements herein or therein, in light of the circumstances under which they
were made, not misleading. As used herein, the term "to the best of the
Corporation's knowledge and belief" shall mean and include, (a) with respect to
matters relating directly to the Corporation or any Subsidiary and its
operations, actual knowledge or that knowledge which a prudent business person
should have obtained in the management of his or her business affairs after
making due inquiry and exercising due diligence with respect thereto, and (b)
with respect to external events or conditions, actual knowledge.

consummation of the transactions contemplated hereby will constitute a violation
of, or a default under, or conflict with, any term or provision of its

         (g) It has (i) such knowledge and experience in business and financial
matters so as to enable it to understand and evaluate the risks of the
Investor's investment in the Shares and form an investment decision with respect

into such transactions.

the First Contingent Closing and the Second Contingent Closing amendments to the
Schedules provided for in Section 3, containing such information concerning
developments or occurrences since the date of the most recently delivered
Schedules (or amendment thereto) as is necessary to cause the representations
and warranties contained in Section 3 to be true and correct, and no development

shall constitute a material adverse change in the business or prospects of the
Corporation, or of the Corporation and the Subsidiaries taken as a whole.

         (ii) All proceedings to have been taken and all waivers and consents to
be obtained in connection with the transactions contemplated by this Agreement

contemplated hereby, and certifying that such resolutions were duly adopted and

Contingent Closing and the Second Contingent Closing, since the date of the most
recent audited consolidated financial statements delivered to the Investor
pursuant to Section 5.1(a)(i)(B)) there has not been any material adverse change
in the consolidated financial condition or operations of the Corporation and the
Subsidiaries, and that except as to the extent reflected in the financial
statements referred to in Section 3.6(i) (or in such later audited financial
statements, as the case may be), and except for liabilities arising in the
ordinary course of business (none of which liabilities either alone or in the
aggregate are material either in nature or amount to the business of the
Corporation, or the Corporation and the Subsidiaries taken as a whole), the
Corporation and the Subsidiaries have no material accrued or contingent
liabilities which are not specifically described in such financial statements.

         (vii) All consents, permits, approvals, qualifications and
registrations (including, without limitation, registration of the Shares)
required to be obtained or effected under the Securities Laws and any applicable

         5.2. Conditions to Obligations of the Corporation.
              --------------------------------------------

         It shall be a condition precedent to the obligations of the Corporation
hereunder that the representations and warranties of the Investor contained
herein shall be true and correct as of the date of the Initial Closing with the
same force and effect as though such representations and warranties had been
made on and as of such date.

         SECTION 6. Covenants of the Investor and the Corporation.
                    ---------------------------------------------

         (a) The Investor covenants as follows:

         (i) The Investor will keep confidential and will not disclose, divulge
or use any confidential, proprietary or secret information which such Investor
may obtain from the Corporation pursuant to financial statements, reports and
other materials submitted by the Corporation to the Investor pursuant to this
Agreement; provided, however, that the Investor may disclose

                                       15

Exchange Commission. Asterisks denote omissions.

such information to its attorneys, accountants, and other professionals to the
extent necessary to obtain their services in connection with its investment in
the Corporation; and provided, further, that the Investor's obligations under
this Section 6(a)(i) shall not apply to information which (A) at the time of
disclosure is in the public domain; (B) after disclosure becomes part of the
public domain by disclosure or otherwise, except by breach of this Section 6(a)
(i) by the Investor; (C) the Investor can establish by competent proof was in
its possession at the time of disclosure and was not acquired, directly or
indirectly, from the Corporation; or (D) the Investor receives from a third
party which was not obtained by such third party, directly or indirectly, from
the Corporation.

         (ii) For the period beginning on the date hereof and ending three (3)
years thereafter (the "Standstill Period"), unless it has obtained the prior
written consent of the Corporation, the Investor will not

         (A) acquire, directly or indirectly, by purchase or otherwise, of
record or beneficially, any voting securities of the Corporation, or rights or
options to acquire voting securities of the Corporation, if after such
acquisition (and giving effect to the exercise of any such rights or options)
the Investor would own of record or beneficially in the aggregate more than
twenty percent (20%) of the voting securities of the Corporation (assuming the
exercise of all outstanding rights or options to acquire voting securities) (the
"20 Percent Limit"); provided that notwithstanding the provisions of this clause
(A), if the number of shares of outstanding voting securities is reduced or if
the aggregate ownership of the Investor is increased as a result of a
recapitalization of the Corporation or as a result of any other action taken by
the Corporation, the Investor will not be required to dispose of any of its
holdings of voting securities even though such action resulted in the Investors'
ownership exceeding the percentage of voting securities which the Investor would
then be permitted to own. Except as otherwise provided above, if the Investor
shall at any time during the Standstill Period own in the aggregate in excess of
the maximum percentage of the voting securities at the time permitted by this
clause (A), (x) the Investor shall sell as promptly as practicable under the
circumstances sufficient voting securities so that after such sale the Investor
shall not own in the aggregate more than the applicable maximum permitted
percentage of voting securities, and (y) the Investor shall refrain from voting
on any matter as to which the holders of voting securities shall have the right
to vote with respect to any voting securities held by the Investor in excess of
the 20 Percent Limit (provided, however, that the foregoing paragraph shall not
be deemed to limit the Corporation's remedies in the event that the excess
voting securities were acquired in violation of this Section);

         (B) "solicit" proxies with respect to voting securities under any
circumstances or become a "participant"

in any "election contest" relating to the election of directors of the
Corporation, as such terms are defined in Regulation 14a under the Securities
Exchange Act of 1934, as amended; deposit any voting securities in a voting
trust or subject them to a voting agreement or other agreement of similar
effect;

         (C) initiate, propose or otherwise   solicit stockholders for the
approval of one or more stockholder proposals at any time, or induce or attempt
to induce any other person to initiate any stockholder proposal; or

         (D) take any action individually or jointly with any partnership,
limited partnership, syndicate, or other group or assist any other person,
corporation, entity or group in taking any action it could not take individually
under the terms of this Agreement;

provided, however, that the restrictions contained in this Section 6 (a) (ii)
shall not apply if (x) any third party or group makes a tender offer or exchange
offer for 20% or more of the voting securities of the Corporation or acquires
20% or more of the voting securities of the Corporation, (y) the Corporation
enters into negotiations with any third party or group concerning acquisition of
the Corporation, or (z) during the period in which the Investor has the right to
designate a member of the Corporation's Board of Directors, the Investor's
designee (if any) for election to the Corporation's Board of Directors (provided
for in Section 6(b)(i)) is not elected by the stockholders of the Corporation.

         (b) The Corporation covenants as follows:

         (i) The Investor shall have the right to designate one individual for
membership on the Corporation's Board of Directors, and the Corporation shall
use reasonable efforts to secure the election of such designee to such Board by
causing such individual to be nominated as a director and presented to the
Corporation's stockholders for election; provided, however, that such right, and
the Corporation's corresponding obligation, shall terminate upon the transfer of
50% or more of the Investor's voting power of the Shares. A transferee of shares
shall not be entitled to the rights granted to the Investor under this Section
6(b)(i).

         (ii) The Corporation will consult with the Investor before issuing any
public announcement of the transactions contemplated by this Agreement. In the
event that the Corporation is required to provide a copy of this Agreement or
any related document to any third party, the Corporation shall ensure that such
document is redacted, to the extent permitted by law, to eliminate all
confidential information. The Investor shall have the right to review and
approve each such document prior to its submission to a third party. A period of
ten business days will be required for such review.

         (iii) The Corporation shall permit the Investor, at the Investor's
expense, to visit and inspect the Corporation's properties, to examine its books
of account and records and to discuss the Corporation's affairs, finances and
accounts with its officers, all at such reasonable times as may be requested by
the Investor; provided, however, that the Corporation shall not be obligated
pursuant to this Section 6(b)(iii) to provide access to any information which it
reasonably considers to be a trade secret or similar confidential information;
and provided, further, that such right shall terminate upon the transfer of 50%
or more of the Investor's voting power of the Shares. A transferee of Shares
shall not be entitled to the right granted to the Investor under this Section
6(b)(iii).

         (iv) The net proceeds received by the Corporation from the Initial
Investment shall be used by the Corporation solely for the continuing
development of GRAFTSKIN skin and tissue equivalents in accordance with
development plans agreed upon by the Joint Development Committee established
pursuant to that certain License and Supply Agreement of even date herewith
between the Corporation and the Investor, including investments in U.S.
manufacturing facilities for GRAFTSKIN skin and tissue equivalents.

other harmless from and against any and all claims, liabilities or obligations
with respect to brokerage or finders' fees or commissions, or consulting fees in
connection with the transactions contemplated by this Agreement asserted by any
person on the basis of any statement or representation alleged to have been made
by such indemnifying party.

by the Investor. Upon receipt of evidence satisfactory to the Corporation of the

destruction or mutilation of any certificate representing any Shares and, in
case of any such loss, theft or destruction, upon delivery of any indemnity
agreement satisfactory to the Corporation, or in case of any such mutilation,
upon surrender and cancellation of such certificate, the Corporation at its
expense will issue and deliver to the Investor a new certificate for such
Shares, of like tenor, in lieu of such lost, stolen or mutilated certificate.

         SECTION 10. Survival of Representations and Warranties.
                     ------------------------------------------

         The representations and warranties of the Corporation (except for those
contained in Section 3.14) shall survive the Closing, for the longer of two
years or the expiration of the respective statute of limitations governing
claims brought with respect to matters pertaining thereto. The representations
and warranties of the Corporation set forth in Section 3.14 shall survive
indefinitely until, by their respective terms, they are no longer operative. All
statements contained in any certificate or other instrument delivered by the
Corporation pursuant to this Agreement or in connection with the transactions
contemplated by this Agreement shall constitute representations and warranties
by the Corporation under this Agreement and shall survive for the longer of two
years or the expiration of the respective statute of limitations governing
claims brought with respect to matters pertaining thereto.

         SECTION 11.  Indemnification.
                      ---------------

this Agreement shall have been breached by any party hereto, the party or
parties entitled to the benefit of such covenants or agreements may proceed to
protect and enforce their rights either by suit in equity or action at law,
including, but not limited to, an action for damages as a result of any such
breach or an action for specific performance of any such covenant or agreement

         9.2 Discontinuation: Sandoz may elect upon sixty (60) days prior notice
             ---------------
to discontinue prosecution or maintenance of any of the Patent Rights in any or
all countries for which Sandoz is responsible. In such case, Organogenesis shall
have the right to prosecute and maintain such patent applications and patents in
such countries it deems appropriate, at its sole expense. Any such patent
application or patent in such country which Organogenesis prosecutes or
maintains shall no longer be part of the Patent Rights and shall be excluded
from the licence granted to Sandoz under this Agreement.

         9.3 Foreign Filing Decisions: If after the end of the ninety (90) day
             ------------------------
period referred to in Art. 9.1 there exists any U.S. patent application which is
part of the Patent Rights as of the Effective Date or which becomes part of the
Patent Rights by the provisions of Art. 4.9 and for which no corresponding
foreign applications have yet been filed, the parties shall consult at an
appropriate time as to whether, and if so in which countries, such foreign
filing should be carried out by Sandoz and at Sandoz' expense. If in any one of
the following countries: Australia, Canada, Israel, Japan, Korea, Mexico, Taiwan
and the countries of the European Patent Convention, Sandoz decides not to file
a corresponding application, Organogenesis shall have the right to file a
corresponding application in such country, at its sole expense. Any such patent
application or patent granted thereon in such country which Organogenesis
prosecutes or maintains shall no longer be part of the Patent Rights and shall
be excluded from the licence granted to Sandoz under this Agreement.

ARTICLE 10.  PATENT INFRINGEMENT
- --------------------------------

         10.1 Warranty: Organogenesis represents and warrants that, to its
              --------
knowledge, there exists no publication or other reason that would adversely
affect the patentability of the subject- matter of or the validity of the Patent
Rights and that it has no information as of the Effective Date to indicate that
Sandoz would not be free to make, use and sell Product in the Territory without
infringing any third party patent.

         10.2 Enforcement: Each party shall promptly notify the other of its
              -----------
knowledge of any potential infringement of the Patent Rights by a third party.
Organogenesis has the right, but not the obligation, to take reasonable legal
action necessary to enforce the Patent Rights in the United States against
infringements by third parties. If within six (6) months following receipt of
such notice from Sandoz, Organogenesis fails to take such action to halt a
commercially significant infringement, Sandoz shall, in its sole discretion,
have the right, at its expense, to take such action in its own name or in the
name of Organogenesis or jointly. Sandoz shall have the right to enforce the
Patent Rights in countries other than the United States in its discretion. If
within six (6) months following receipt of notice from Organogenesis, Sandoz
fails to take such action to halt a commercially significant infringement,
Organogenesis shall, in its sole discretion, have the right, at its expense, to
take such action in its own name or in the name of Sandoz or jointly. Each party
agrees to render such reasonable assistance as the prosecuting party may
request. Costs of maintaining any such action and damages recovered therefrom
shall be paid by and belong to the party bringing the action. Sandoz shall not
enter into any settlement which admits or concedes that any aspect of the Patent
Rights is invalid or unenforceable without the prior written consent of
Organogenesis.

         10.3 Infringement Claims: If the manufacture, sale or use of Product
              -------------------
pursuant to this Agreement results in any claim, suit or proceeding lodged by a
third party alleging patent infringement by Organogenesis or Sandoz (or its
Affiliates or Sublicensees), such party shall promptly notify the other party
hereto in writing. The party subject to such claim shall have the exclusive
right to defend and control the defense of any such claim, suit or proceeding,
at its own expense, using counsel of its own choice; provided, however, that
Sandoz shall not enter into any settlement which admits or concedes that any
aspect of the Patent Rights is invalid or unenforceable without the prior
written consent of Organogenesis. The party subject to the claim shall keep the
other party hereto reasonably informed of all material developments in
connection with any such claim, suit or proceeding.

ARTICLE 11.  TRADEMARKS
- -----------------------

         Sandoz and its Affiliates shall be free to use and to register in any
trademark office any trademark for use with Product they desire in their sole
discretion. Sandoz shall own all right, title and interest in and to any
trademark in its own name or that of its Affiliates during and after the term of
this Agreement. At Sandoz' request, Organogenesis agrees to exclusively license
to Sandoz free of charge all rights in the trademark GRAFTSKIN.

ARTICLE 12.  MANUFACTURING AND SUPPLY
- -------------------------------------

         12.1 Supply by Organogenesis: Subject to Art. 12.3 below, Sandoz agrees
              -----------------------
to purchase exclusively from Organogenesis, and Organogenesis agrees to sell
exclusively to Sandoz during

the term of the Agreement, Sandoz' total worldwide requirements for Product. No
later than three (3) months after the Effective Date, the parties shall enter
into a separate Manufacturing and Supply Agreement which shall provide, among
other matters, for the setting up of a Joint Manufacturing Committee to ensure
adequate supplies of Product including setting strategies for the European
Manufacturing Facility described in Art. 12.3 below; for a system of advance
ordering of requirements by Sandoz; and for quality control of Product. Such
Manufacturing and Supply Agreement shall terminate no later than the expiry of
the present Agreement in all countries under Art. 16.1. No later than six (6)
months before such date, Sandoz shall notify Organogenesis whether it wishes to
extend the supply period for all or part of Sandoz's worldwide requirements for
Product for a further period, in which case a further Supply Agreement will be
negotiated in good faith and entered into by the parties. If no such further
Supply Agreement is concluded between the parties, then Sandoz shall have the
right to manufacture Product itself or have Product manufactured by a third
party of its choice, based on full technical assistance and know-how, including
full documentation, relating to Product and Improvements to be supplied free of
charge by Organogenesis.

         12.2 U.S. Manufacturing Facility: Organogenesis will assume full cost
              ---------------------------
and responsibility for constructing, operating and maintaining a U.S.
manufacturing facility capable, in conjunction with any European manufacturing
facility as provided for in Art. 12.3 below, of supplying the expected
commercial requirements of Sandoz worldwide in accordance with the supply
provisions of Art. 12.1 above, and with the provisions of the Manufacturing and
Supply Agreement to be entered into by the parties. Such Manufacturing and
Supply Agreement shall provide that if Organogenesis is unable to supply more
than a certain percentage, to be negotiated, of Sandoz' duly forecasted
requirements of Product meeting the agreed specifications, then Sandoz shall
thereafter have the right to manufacture Product itself or to have Product
manufactured by a third party of its choice, based on full technical assistance
and know-how, including full documentation, relating to Product and Improvements
to be supplied free of charge by Organogenesis. In the event that such inability
to supply is proved to be due to negligence on the part of Organogenesis, then
no royalties shall be payable on Net Sales of Product during a time sufficient
for Sandoz to recover out of the royalties that would otherwise by paid to
Organogenesis such lost profits as it may have sustained as a result of
Organogenesis' inability to supply; thereafter royalties shall be payable as
before.

         12.3 European Distribution Center and Manufacturing Facility: Sandoz
              -------------------------------------------------------
agrees to invest up to ****************************** in the construction of a
new facility at one of Sandoz' existing manufacturing sites in Europe, said
facility to consist of a) a Distribution Centre for the thawing of cryopreserved
Product and distribution of Product to end users in Europe, and b) "shell"
premises (building and basic utilities) capable of being equipped as a
manufacturing facility for Product. Upon Sandoz' receipt of building permission
for such facility or by **************, whichever is later, Organogenesis shall
have the option of leasing and operating such facility under the terms of a
separate Leasing Agreement to be entered into between the parties, which
Agreement shall provide, among other matters, for repayment of Sandoz's
investment plus reasonable interest over a period of not more than ten (10)
years. If Organogenesis exercises such option, Organogenesis shall fund all
additional costs of said facility, including equipment and operating costs. If
Organogenesis does not exercise such option, or if Organogenesis, having
exercised such option, does not within one (1) month of the date on which the
option was exercised begin site planning and place orders for the purchase of
all necessary equipment, then Sandoz shall have the right within Europe to
manufacture Product itself or have Product

manufactured by a third party of its choice, based on full technical assistance
and know-how, including full documentation, relating to Product and Improvements
to be supplied free of charge by Organogenesis.

         12.4 Supply Price: For a period of eighteen (18) months from the First
              ------------
Commercial Sale of Product in the first Primary Country in the Territory, the
Supply Price shall be *************** ******. Within three (3) months from the
end of said period the Supply Price shall be reviewed by the parties in good
faith, and shall ********* **************** ****** unless the ****************
******************** on sales of Product is *************************** ******,
in which case the Supply Price shall be ******* so as to
******************************************************* **** ****************.
Thereafter, if in any June or December in a calendar year within the term of
this Agreement, Sandoz can demonstrate to Organogenesis that its
**************** ********************* sales of Product in the last six (6)
month period for which Sandoz has sales records was ********* ****, then
Organogenesis agrees ********* the Supply Price and/or the royalty level,
effective from the beginning of the following half year, so as to assure Sandoz
that *************************** in the following half year. Any figures relied
upon by Sandoz to support its *********************************************
shall be open to review by an independent accounting firm acceptable to both
parties, at Organogenesis's expense, for the sole purpose of verifying their
accuracy. The price charged to Sandoz for a four by eight (4 x 8) inch
rectangular unit of Product shall be negotiated in good faith by the parties at
such time as Sandoz is able to provide sales volume projections for units of
this size. The ********* Supply Price of ****** ******* ***** per unit shall be
subject to annual adjustment to reflect changes in Sandoz' average selling price
in the Primary Countries, starting two (2) years after the First Commercial Sale
of Product in the first Primary Country in the Territory.

         12.5 Non-Commercial Supply: All quantities of Product reasonably
              ---------------------
required by Sandoz for commercial samples and clinical trials shall be supplied
by Organogenesis at a price of ****** ******* ***** per unit in the first year
following the Effective Date, ******************** ***** per unit in the second
year, and ****************** ****** per unit thereafter, subject to annual
adjustment to reflect changes in the U.S. Consumer Price Index, starting from 1
January 2000.

ARTICLE 13.  DISTRIBUTION
- -------------------------

         Sandoz will assume cost and responsibility for shipping Product from
the manufacturing facility in the United States to the end user in the United
States. Organogenesis will assume cost and responsibility for shipping Product
in bulk to a designated distribution center in Europe for sale of Product in
Europe and for the packaging of Product within said distribution center
(including any necessary thawing step), and Sandoz will assume cost and
responsibility for delivering Product from said distribution center to the end
user in Europe.

ARTICLE 14.  PRODUCT LIABILITY
- ------------------------------

         14.1 Negligence: Organogenesis shall indemnify and hold Sandoz harmless
              ----------
from all losses, costs or damages which Sandoz may be held liable to pay as a
result of claims or suits arising out of any injuries to persons and/or damage
to property arising from Organogenesis's negligence with respect to the subject
matter of this Agreement. Sandoz shall indemnify and hold Organogenesis harmless

this Agreement.

         14.2 Other Claims: Third party claims not related to negligence of

either party shall be handled as agreed by the insurance companies of the
parties (both parties agree to have sufficient third party liability insurance
and/or self coverage) or in accordance with the laws of the country or countries
in which a claim is submitted.

         14.3 Tissue Donor Release: Organogenesis warrants that any donor of
              --------------------
tissue used to generate the cell bank used in the manufacture of Product, or his
parent or guardian, has signed or shall sign a release giving informed consent
to the use of the tissue for commercial purposes.

         14.4 Reporting: Each party hereto agrees to report promptly to the
              ---------
other party any information concerning serious or unexpected side effects,
injury, toxicity, reactions or any unexpected event associated with clinical,
investigational or commercial use whether or not finally attributable to
Product. Such information shall also include pre-existing diseases, syndromes,
or abnormal diagnostic tests results which re-appear or are exacerbated by use
of Product. Upon receipt of such information by either party hereto, both
parties shall promptly consult each other and use best efforts to arrive at a
mutually acceptable procedure for taking the appropriate actions under the
circumstances; provided, however, that nothing contained herein shall restrict
the right of either party to make a submission to a regulatory authority or take
other actions it deems to be appropriate or necessary. This Article shall
survive termination of this Agreement.

DEFINITION OF PRODUCT

Graftskin is a manufactured skin equivalent product, designed to mimic the
structure and function of human skin. Graftskin consists of two layers--the
upper layer contains human keratinocytes and the lower layer contains Type I

to 75 mm. The thickness of the device is between 0.5 and 0.75 mm. Fresh
Graftskin can be stored at room temperature for three days, in a 37 degree
incubator for seven days or at liquid nitrogen temperatures indefinitely.

Graftskin is intended for use in the following conditions:

 .        venous stasis ulcers
 .        dermatological surgery
 .        burns
 .        diabetic ulcers
