ITEM 1.

BUSINESS

GENERAL

Genzyme Transgenics Corporation ("GTC" or the "Company") has established a
leadership position in the application of transgenic technology to the
development and production of genetically engineered proteins for therapeutic,
diagnostic and other biomedical uses, both in collaboration with pharmaceutical
and biotechnology companies and independently. To date, GTC has produced more
than 27 such proteins. For its lead compound, Antithrombin III ("AT-III"), the
Company has completed a Phase I human clinical trial, and has initiated a Phase
II clinical study. GTC is also a leading Contract Research Organization ("CRO"),
providing services such as preclinical efficacy and safety testing, in vitro
testing and formulation development to pharmaceutical, biotechnology, medical
device and other companies. Revenues for the Company's testing and production
services in 1996, which included the results of BioDevelopment Laboratories,
Inc. ("BDL") for the full year, were $38.5 million, an increase of 46% from
1995, which included the results of BDL for six months.

GTC produces recombinant proteins transgenically by inserting, into the
genetic material of an animal embryo, a gene that directs the production of a
desired protein in the milk of female offspring. The Company believes that
transgenic production offers significant economic and technological advantages
relative to traditional protein production systems, including reduced capital
expenditures and lower direct production cost per unit for complex proteins. For
proteins currently derived from pooled human plasma, transgenic production
provides an alternative source, free from the risks of transmission of human
viruses and other adventitious agents. In the case of certain complex proteins,
transgenic production may represent the only technologically and economically
feasible method of commercial production. To date, GTC has expressed 14 proteins
at levels of one gram per liter or higher, more than 10 times the level
typically achieved for comparable proteins in conventional cell culture systems.

GTC's most advanced product candidate is transgenic AT-III, an
anticoagulant normally present in human serum. Plasma-derived AT-III is an
approved therapy for inherited AT-III deficiency and for certain acquired
deficiencies. Worldwide sales of plasma-derived AT-III were approximately $200
million in 1994. The Company believes transgenic AT-III may represent a more
attractive product in light of safety considerations, the limited volume of
AT-III available from plasma and the impracticality of producing sufficient
quantities of recombinant AT-III by cell culture methods. GTC has expressed
transgenic AT-III in goats, demonstrating stable expression across multiple
generations and successive lactations. Further, GTC has purified transgenic
AT-III to clinical grade with attractive yields. Preclinical safety and
efficacy studies and a Phase I human safety study have been successfully
completed. GTC filed an Investigational New Drug application (an "IND") with
the FDA to initiate a Phase II clinical trial for this product, which began in
the fourth quarter of 1996.

Other significant plasma proteins under development by GTC include Alpha-I
Proteinase Inhibitor ("API") and Human Serum Albumin ("HSA"), which is now being
developed in conjunction with Fresenius AG. Additionally, GTC is working with
other corporate partners such as Bristol-Meyers Squibb and BASF on a number of
monoclonal antibodies and other recombinant proteins. The Company is also
developing transgenic production processes for other proteins, including
prolactin, insulin and a protein for use in a malaria vaccine, and is in
commercial discussions with prospective partners for other products.

The Company's CRO operations are focused on enabling its clients to meet
regulatory testing and other product development needs quickly and effectively
by offering a fully integrated line of services. GTC's laboratories focus on
providing high value, scientifically differentiated services to clients,
including preclinical efficacy testing, experimental surgery, photobiology and
reproductive toxicology testing as well as formulation development. GTC uses its
technological capabilities to introduce new services that improve the ability of
its customers to develop their products successfully. The Company's
comprehensive programs link its preclinical and manufacturing support services
in order to reduce the time and expense of bringing new therapeutics or other
products to market.

As an outgrowth of production services performed for the National Cancer
Institute (the "NCI"), the Company has developed technology for the production
of idiotypic vaccines, in which a cancer patient's own tumor cells are used to
enhance the immune system's ability to prevent the regrowth of tumors. Idiotypic
vaccines produced by GTC have shown promising results, including the absence of
disease for over six years in four of nine lymphoma patients




treated. Results from this program have been reported in the October 1992
issue of The New England Journal of Medicine and the May 1995 issue of The
Lancet. GTC and the NCI signed a letter of intent for a Collaborative Research
and Development Agreement ("CRADA") in 1996. The Company expects to finalize
the CRADA and expand clinical trials in 1997.

TRANSGENIC PRODUCTION

OVERVIEW AND STRATEGY

A growing number of recombinant proteins are being developed by
pharmaceutical, biotechnology and other companies for therapeutic, diagnostic
and nutriceutical applications. Many of these proteins have proven difficult or
expensive to produce in the quantities required using conventional methods, such
as bacteria, yeast or mammalian cell sources. Moreover, bacteria or yeast
systems cannot produce many complex proteins. While mammalian cells can produce
certain complex proteins, they are generally more difficult and expensive to
grow and often produce lower volumes of protein. Proteins produced by the
Company transgenically have been expressed at concentrations significantly
greater than those typically achieved using conventional methods.

Transgenic technology uses in vitro microinjection or other techniques to
introduce a genetically engineered segment of exogenous DNA (an "expression
vector") into the genetic material of a fertilized egg or early stage animal
embryo. Two types of genetic instructions are incorporated into the expression
vector: the coding sequence and the promoter sequence. Coding sequences
instruct the cells of the animal to express a specified protein. Promoter
sequences direct the expression of proteins at appropriate times and by
specific tissues or cell types. The modified embryo is then transferred to a
recipient female. Transgenes are successfully integrated into the genetic
makeup of only a small percentage of the embryos that are microinjected;
therefore multiple microinjection candidates are required. If successful, the
resulting animal, when mature and lactating, will express the desired protein.
Once established in the first generation of transgenic animals, the transgene
is transmitted like other genetic traits to future generations through
traditional breeding with either non-transgenic or other transgenic animals.

The Company believes transgenic production offers significant economic and
technological advantages over traditional methods of protein production,
including reduction in the total amount of required capital expenditures, lower
direct production cost per unit and reduced risk of transmission of human
viruses and other adventitious agents. For certain complex proteins, transgenic
production may represent the only technologically and economically feasible
method of commercial production. To date, the Company has produced such proteins
principally using goats, which offer an attractive combination of large milk
volumes, relatively short generational time periods and ease of handling and
milking.

GTC's strategy is to commercially produce proteins by use of transgenic
technology both by (i) entering into contracts with biotechnology and
pharmaceutical companies to utilize the Company's transgenic services in
exchange for revenue, royalties and, possibly, marketing rights to the resulting
product and (ii) independently identifying proteins in the public domain,
proteins covered by lapsing patents and proprietary proteins available for
license which represent attractive candidates for transgenic production and
funding development of such proteins itself or seeking corporate partner
funding.

GTC has entered into funding contracts for the development of AT-III, other
plasma proteins, certain monoclonal antibodies and other products.

Achievements to Date:

Over the past few years, GTC has shown the feasibility of transgenic protein
production by the achievement of specific milestones:

To date, GTC has produced 27 different transgenic proteins in animals, 14
at concentrations of one gram per liter or greater and one protein in
excess of 35 grams per liter, levels often many times higher than those
achievable in other production systems.

The Company has produced a significant number of transgenic goats. GTC
maintains a herd of over 500 goats at its facility in Massachusetts as
well as an additional 150 goats at Tufts University School of




Veterinary Medicine ("Tufts"). Over 40 of these goats are transgenic,
each expressing one of five different proteins.

Stability of expression has been demonstrated across lactations, and, for
two proteins, across two generations expressing the same transgene.

Together with Genzyme Corporation ("Genzyme"), GTC has been able to
achieve clinical grade purity for a transgenically produced protein at
high recovery levels. This transgenic protein has been extensively
characterized and its pharmacodynamic properties in animal models have
been shown to be comparable to those of the same protein from other
sources.

GTC completed a Phase I human safety clinical trial, filed an IND with the
Food and Drug Administration (the "FDA"), and initiated a Phase II
clinical trial in patients undergoing coronary artery bypass surgery.

TRANSGENIC PRODUCTS UNDER DEVELOPMENT

Antithrombin III. AT-III is an anticoagulant normally present in human
serum. Decreased levels of AT-III are found in individuals who have either a
hereditary or an acquired deficiency of AT-III. The hereditary deficiency has
an incidence rate of 1 in 2,000 to 1 in 20,000. Individuals with hereditary
AT-III deficiency have an increased tendency towards blood clots (thromboses)
and are treated with AT-III protein replacement therapy during periods when
they are at high risk for clots, such as during surgery. Acquired AT-III
deficiency occurs in many disease states as a result of several possible
causes, including a decrease in the amount of AT-III produced, an increase in
the rate of AT-III consumption or an abnormal loss of AT-III from the
circulation. Examples of such conditions include acute liver failure,
disseminated intravascular coagulation, sepsis and septic shock, burns,
multiple organ failure, bone marrow and other organ transplantation and
hemodialysis.

Plasma-derived AT-III is approved for use in Europe and Japan for treatment
of both acquired and hereditary AT-III deficiency. In the United States,
plasma-derived AT-III is currently approved for use only for hereditary AT-III
deficiency. The worldwide market for plasma-derived AT-III was approximately
$200 million in 1994.

GTC believes transgenic AT-III may represent a more attractive product in
light of the risks of viral transmission from pooled plasma products in general,
the limited volume of AT-III currently available from plasma and the
impracticality of producing sufficient quantities of recombinant AT-III in cell
culture systems. The Company also believes that a lower cost, higher volume
alternative to plasma-derived AT-III will further expand the use of AT-III in
clinical settings.

GTC has produced multiple transgenic goats carrying the AT-III gene and has
selected a founder goat from which a production herd is being generated. This
genetic line expresses AT-III at levels of approximately two grams per liter.
The processes for production and purification have been implemented and result
in a product that is purified to clinical grade at attractive yields.
Preclinical safety and efficacy studies for AT-III have been successfully
completed. The Company filed an IND with the FDA for the use of transgenic
AT-III as a potential treatment for AT-III deficiency that occurs during certain
vascular surgeries, including cardiopulmonary artery bypass grafting, and a
Phase II clinical study for this indication has been initiated.

GTC is developing recombinant human AT-III under a license from Behringwerke
AG, subject to a royalty obligation. In March 1996, GTC and Genzyme signed an
agreement pursuant to which Genzyme is funding the development of AT-III through
the first quarter of 1997. Genzyme has been granted co-marketing rights to
transgenic AT-III in Europe and the United States, subject to its entering into
a further agreement with GTC by March 31, 1997. GTC and Genzyme are currently
negotiating the terms of such an agreement. If the parties do not enter into
such an agreement, all marketing rights revert to GTC and GTC may continue to
pursue development of transgenic AT-III on its own or may seek another corporate
partner. SMI Genzyme Ltd., a joint venture between Genzyme and Sumitomo Metal
Industries Ltd. (the "Joint Venture"), which contributed development funding for
AT-III through December 1995, retains marketing rights to transgenic AT-III in
Asia. In February 1997, the Company reached agreement with the Joint Venture,
subject to approval by the Board of Directors of the Joint Venture, under which
GTC will receive future milestone payments for the development of AT-III, which,
if achieved, could total as much as $4.4 million in revenue.




Alpha1-Proteinase Inhibitor ("API"). API is a serine protease inhibitor
which is normally present in human plasma. In certain pulmonary diseases,
including congenital alpha1-antitrypsin ("AAT") deficiency and cystic fibrosis,
patients develop chronic emphysema. Although the precise mechanism is uncertain,
researchers believe that the development of emphysema results from a chronic
imbalance between elastase and API, which is deficient in patients with
hereditary AAT deficiency. Plasma-derived API is approved in the United States
for parenteral use in the treatment of patients with congenital AAT deficiency.
Treatment of AAT deficiency focuses on chronic replacement therapy with API to
restore the elastase/ elastase inhibitor balance. Dosing requirements are high,
averaging four grams per week for a 150-pound patient.

An imbalance between elastase and elastase inhibitors also occurs in
cystic fibrosis, which is the most common fatal genetic disease among
Caucasians, occurring in one in every 2,500 infants born in the United States.
Based on preliminary data, the Company believes that aerosol administration of
API to cystic fibrosis patients may be effective in reducing the level of
neutrophil elastase in the lung, thereby reducing elastase-induced pulmonary
tissue degradation and fibrosis.

GTC believes that transgenic API may represent a more attractive product
than plasma-derived API in light of risks of viral transmission from donor
plasma products, and that it will be more economical to produce and more widely
available than the plasma-derived products. The ability to produce large
quantities of transgenic API may enable the Company to pursue other indications
for this product, such as atopic dermatitis, in which an imbalance of proteases
is also implicated.

GTC has expressed API at levels equivalent to 35 grams per liter in a mouse
model. Several transgenic founder goats have been generated, including at least
one line which expresses API in excess of 10 grams per liter. The Company has
acquired an option to license certain patents relating to the use of API for
certain indications. To date, GTC has funded the development of API internally.

Human Serum Albumin ("HSA"). HSA is the protein principally responsible for
maintaining oncotic pressure, plasma volume and the balance of fluids in blood.
It is critical to the transport of amino acids, fatty acids, enzymes and
hormones in the blood stream. The therapeutic use of HSA is indicated in
situations of blood loss and decreased blood albumin levels which can occur
during shock, serious burns, pre- and post-operative conditions and gastric and
intestinal malfunctions. HSA is currently produced by human plasma
fractionation, with 1994 worldwide sales in excess of $1.3 billion.

For HSA and all human blood sourced products, the theoretical risk of virus
transmission, including HIV and hepatitis, remains a concern despite efforts to
improve screening and purification techniques.

Prices for HSA are expected to rise due to a number of factors, including
increasing costs of testing and purifying protein fractions sourced from human
plasma, the replacement of high margin plasma fractions with safer recombinant
versions, and decreasing blood donations in the face of increasing demand.
Transgenic production of HSA would eliminate the risk of human viral
transmission and help ensure the delivery of safe therapeutics at competitive
prices.

GTC has expressed transgenic HSA in mice at levels equivalent to or greater
than 35 grams per liter. Because the Company has demonstrated that the mouse
system is highly predictive to that of dairy animals, the Company believes it
will be able to produce transgenic HSA in cows at commercial scale. An
individual dairy cow will produce approximately 8,000 liters of milk per year,
or an estimated 80 kilograms of albumin per year. This level of productivity
will provide Genzyme Transgenics with the ability to produce HSA at costs
competitive with albumin sourced from human blood. The Company believes that HSA
is not the subject of any composition of matter patent, and has entered into an
agreement with Fresenius AG of Bad Homburg, Germany, to further develop and
commercialize transgenic HSA.

MONOCLONAL ANTIBODIES. Monoclonal antibodies are immune system proteins
that can find and attach to specific biological targets in the body. Recent
advances in developing humanized and human antibodies, single chain antibodies
and conjugated antibodies have added to the potential value of these therapeutic
agents. More than 50 monoclonal antibodies are now in clinical trials sponsored
by pharmaceutical and biotechnology companies with many more in development as
therapeutics for cancer, cardiovascular disease, immune system disorders for use
and against a wide variety of infectious agents, such as viruses and bacterial
infections. GTC is now




collaborating with pharmaceutical and biotechnology companies for the
transgenic production of a number of therapeutic monoclonal antibodies.

Bristol-Myers Squibb ("BMS"), a leading pharmaceutical company
specializing in cancer treatment, has entered into an agreement with GTC for
transgenic production in goats of its BR-96 monoclonal antibody, a potential
therapy for breast and lung cancer. BMS' approach is to use the BR-96 antibody
to deliver a traditional chemotherapeutic agent, doxorubicin, directly to
cancer sites in the body. The expected effect is to achieve greater impact on
the cancer while reducing toxicities associated with doxorubicin. In this
program, several goats have recently been born at GTC's farm carrying the
BR-96 transgene. BMS has tested BR-96 produced in the milk of mice, confirming
its comparability to BR-96 made in cell culture. The initial product samples
from founder female goats are expected in the first six months of 1997.

GTC currently has five other funded antibody development programs underway.
One, an anti-colon cancer antibody, produced on behalf of a Japanese
pharmaceutical company, has been expressed in the milk of goats at four grams
per liter. Other programs, on behalf of NovoPharm, Behringwerke AG, NeoRx
Corporation and Boehringer Mannheim GmbH, are in early stages. The Company is in
active discussions with a number of other pharmaceutical and biotechnology
companies for the transgenic development of therapeutic antibodies.

INSULIN. Current worldwide sales of insulin products are more than $3
billion annually. Recombinant DNA insulin now accounts for approximately 50% of
the market.

GTC has expressed insulin precursors at the equivalent of more than eight
grams per liter in the milk of mice, which provides for the potential to
manufacture insulin on a highly cost effective basis. GTC has taken initial
steps to develop appropriate insulin processing and purification procedures, and
the Company believes that there are several approaches to the manufacture of a
transgenic insulin that may offer cost benefits compared to current products.
Insulin is not the subject of any known patents that could foreclose the
Company's development program.

PROLACTIN. In collaboration with Genzyme, GTC has developed multiple
transgenic mouse lines which express prolactin at levels in excess of the
equivalent of one gram per liter. Prolactin is a human hormone which has
numerous biological activities, including stimulation of the immune system.
Genzyme has licensed patents covering recombinant prolactin and the parties are
jointly exploring the development of transgenic prolactin for multiple clinical
indications, and for the infant and specialty nutritional product markets. GTC
recently initiated a program to develop transgenic goats which express prolactin
in their milk.

Malaria Vaccine. GTC's transgenic expression system has the potential to
express the correct, immunogenic protein for use as a malaria vaccine both
economically and on a large scale. Malaria is a disease that has an annual
incidence of more than 300 million people worldwide and results in several
million deaths annually. GTC is working with the U.S. National Institutes of
Health (the "NIH") and the Federal Malaria Vaccine Coordinating Committee to
transgenically express a malaria vaccine and to examine the options for
commercializing the vaccine.

TransGenerics. GTC has a program to identify and develop transgenic
production systems for the first generation of approved recombinant drugs as
they come off patent. These drugs, many of which have established significant
markets, may become vulnerable to competition from transgeneric versions which
are more cost effective. GTC is in discussions with both generic and proprietary
pharmaceutical and biotechnology companies with strategic and product-specific
interests in the TransGenerics program.

CRO SERVICES

OVERVIEW

Contract research organizations provide testing and development services to
pharmaceutical, biotechnology, medical device and other companies, as well as to
certain government agencies. The industry is divided generally into companies
which conduct human clinical trials and those providing non-clinical services,
including preclinical testing, clinical trial support and other development
services. The worldwide revenues for non-clinical CRO services were in excess of
$1 billion in 1996.




The growth of the CRO market has been influenced by several factors.
First, cost control pressures on large pharmaceutical firms are leading them
to focus on core competencies, often resulting in a reduction in the size and
capacity of in-house, non-clinical testing departments. Second, emerging
biotechnology and medical device companies often have and can afford little
infrastructure dedicated to such functions. Third, new scientific developments
continue to lead to new fields of safety testing. Fourth, regulatory changes
have mandated additional testing requirements. Fifth, the need for services,
such as efficacy models and formulation development, increases as
pharmaceutical companies venture further from their traditional bases in
search of breakthrough products.

GTC believes that it has built one of the premier non-clinical CROs in the
industry. The Company believes that it has a broader set of value-added services
than any of its competitors and is differentiated by its ability to offer
comprehensive development programs. The Company has the ability to perform
virtually all of the safety, efficacy and quality control testing, as well as to
provide the regulatory affairs expertise necessary to bring a client's early
research-stage product to the start of Phase I clinical trials.

OPERATIONS AND TECHNICAL CAPABILITIES

GTC acquired its CRO capabilities through the acquisitions of TSI
Corporation ("TSI") in October 1994 and BioDevelopment Laboratories, Inc.
("BDL") in June 1995. GTC conducts its CRO services through five laboratories:
Mason Laboratories (Worcester, Massachusetts); Argus Research Laboratories
(Horsham, Pennsylvania); Redfield Laboratories (Redfield, Arkansas); Washington
Laboratories (Rockville, Maryland) and BDL (Cambridge, Massachusetts).

GTC's laboratories focus on providing high value, scientifically
differentiated services to its clients. Fields in which GTC provides contract
services include:

- Preclinical Efficacy Testing measures the effectiveness of a drug
candidate prior to human clinical trials. GTC believes that its Mason
Laboratories facility has the only comprehensive preclinical efficacy
services in the CRO marketplace utilizing a wide variety of disease models
and expertise intended to assist clients in designing optimal clinical
trials.

- Experimental Surgery to support toxicology programs enables GTC scientists
to test novel routes of administration for biotechnology products which
cannot be delivered through standard routes. GTC believes that its Mason
Laboratories facility has the leading surgical capabilities in the
preclinical CRO marketplace and has the ability to perform studies which
are unavailable from other CROs.

- Photobiology Testing measures a drug candidate's potential interactions
with the sun. GTC believes that the FDA will require an increasing number
of products to be tested for these effects. GTC has the only CRO
facilities capable of performing a full range of phototoxicology and
photocarcinogenesis testing.

- Developmental and Reproductive Toxicology Testing measures a drug
candidate's potential impact on a fetus. GTC believes that its Argus
Research Laboratories facility has performed more
teratology studies than any other laboratory in the industry and is widely
recognized as the leader in the field.

- Diet Optimization for carcinogenicity studies has been shown to reduce
variability in tumor growth and mortality. GTC believes that these studies
offer improved quality at a lower price than would be possible without
diet optimization. GTC's Redfield Laboratories facility is the only CRO
facility to have validated multiple strains of test animals for these
studies.

GTC has also made significant investments in bioanalytical chemistry
services to support clinical trials, drug formulation development and lot
release testing for biopharmaceuticals. The Company believes that its
experience in related areas, its client base and its sales force enables it to
compete effectively in these fields. Clients have recently contracted with GTC
for testing services for major programs in each of these areas, and GTC is
pursuing opportunities which may, if successfully concluded, lead to growth in
each field. GTC believes that its ability to provide high value,
scientifically differentiated services, combined with its traditional
strengths in toxicology, pharmacokinetics, cell line testing and production
and regulatory affairs, offers clients the broadest




set of preclinical services available in the CRO industry.

GTC believes the key to sustaining superior performance in this field will
be in providing services in a close, collaborative relationship in which
customers are able to receive scientific services from GTC at levels equal to or
greater than that which they could receive from an in-house department. Toward
this end, GTC has also made significant investment in people, technology and
programs since its acquisition of TSI, increasing the numbers of doctoral level
employees by 42% since the acquisition. GTC believes that its testing services
strategy has been validated by the growth in its business since the acquisition
of TSI in October 1994. Revenues for the Company's testing and production
services in 1996, which included the results of BDL for the full year, were
$38.5 million representing a 46% increase compared to 1995, which included the
results of BDL for six months.

IDIOTYPIC CANCER VACCINES

GTC's Washington Laboratories has been producing experimental cancer
vaccines for the NCI under contract since 1993. These vaccines have shown
preliminary efficacy in early clinical trials. In 1996, the Company signed a
letter of intent to enter into a Collaborative Research and Development
Agreement ("CRADA") with the NCI to expand these clinical trials and to gain
development rights to the program.

Idiotypic cancer vaccines are autologous therapeutics, requiring that
immunoglobulin harvested from individual patients be expanded in separate cell
cultures. Vaccines are produced at the NCI and Washington Laboratories and are
given to patients upon the completion of chemotherapy. The vaccine activates the
patient's immune system to destroy cancer cells which remain after traditional
chemotherapy regimens.

The principal clinical focus of the work today is on B-cell lymphoma, with
secondary efforts on multiple myeloma and other related malignancies. There are
over 40,000 newly diagnosed cases of B-cell lymphoma in the United States each
year. Most patients initially respond favorably to chemotherapy, but the cancer
has a 70% to 90% mortality rate, with patients typically relapsing within two to
three and one half years.

Idiotypic vaccines produced by GTC have shown promising results, including
the absence of disease for over six years in four of nine lymphoma patients. The
first myeloma patient treated experienced a remission of three and one half
years. Results from this program have been reported in the October 1992 issue of
The New England Journal of Medicine and the May 1995 issue of The Lancet. GTC is
currently producing vaccines to treat two patients per month, and expects to
expand clinical trials upon the signing of the CRADA in 1997. The production
costs for these vaccines will be shared by the NCI and GTC.

RELATIONSHIP WITH GENZYME

EQUITY POSITION.

Genzyme is the largest single stockholder of the Company, currently holding
7,428,365 shares of Common Stock, representing approximately 43% of the
outstanding GTC Common Stock. Genzyme also holds a Common Stock Purchase Warrant
(the "Genzyme Warrant") exercisable for 145,000 shares of Common Stock at a
price of approximately $2.84 per share, the market price of the Common Stock at
the time the warrant was issued.

Four million of Genzyme's shares in GTC were acquired in 1993 at the time
of the Company's organization in exchange for the transfer of certain assets
to the Company. In February 1995, 500,000 shares were sold to Genzyme at $8.00
per share, upon exercise by GTC of a put agreement entered into at the time of
the Company's initial public offering. Genzyme received 1,333,333 shares in
1995 and 219,565 shares in 1996 in exchange for conversion of debt at the then
current market prices. In July 1995, 475,467 shares were issued to Genzyme in
exchange for shares of Genzyme common stock delivered as a portion of the
consideration for the acquisition of BDL. The remaining 900,000 shares were
purchased by Genzyme as part of the August 1996 Public Offering. The Genzyme
Warrant, which expires on July 3, 2005, was issued to Genzyme in consideration
of Genzyme's guaranty of the Company's indebtedness to a commercial bank
discussed below. All of the shares held by Genzyme are entitled to certain
registration rights.

Arrangements Regarding Technology and Product Development. GTC and Genzyme
have entered into a number of agreements regarding technology and product
development discussed below:




TECHNOLOGY TRANSFER AGREEMENT. Under the Technology Transfer Agreement
dated May 1, 1993, Genzyme transferred substantially all of its transgenic
assets and liabilities to GTC, including its ownership interest in SMI Genzyme
Ltd., a joint venture between Genzyme and Sumitomo Metal Industries Ltd. (the
"Joint Venture") assigned its relevant contracts and licensed to the Company
technology owned or controlled by it and relating to the production of
recombinant proteins in the milk of transgenic animals (the "Field") and the
purification of proteins produced in that matter. The license is worldwide and
royalty free as to Genzyme, although GTC is obligated to Genzyme's licensors for
any royalties due them. As long as Genzyme owns less than 50% of GTC, Genzyme
may use the transferred technology, or any other technology it subsequently
acquires relating to the Field, without any royalty obligation to the Company,
provided Genzyme may not offer transgenic production services to third parties.

R&D Agreement. Pursuant to the R&D Agreement, Genzyme and GTC agreed, until
May 1, 1998, to provide research and development services to the other relating,
in the case of GTC, to transgenic production of recombinant proteins and, in the
case of Genzyme, to the purification of such proteins. Each company receives
payments from the other equal to the performing party's fully allocated cost of
such services, which can be no less than 80% of the annual budgets established
by the parties under the R&D Agreement, plus, in most cases, a fee equal to 10%
of such costs.

AT-III Development Funding. Under the Convertible Debt and Funding
Agreement, Genzyme agreed to fund transgenic AT-III development through the
first quarter of 1997 in exchange for co-marketing rights to AT-III in all
territories other than Asia. Such marketing rights will terminate if a further
agreement is not executed by the parties prior to March 31, 1997. GTC and
Genzyme are currently negotiating the terms of such an agreement. See
"Business--Transgenic Production."

Other Arrangements. GTC and Genzyme have also entered into the following
other arrangements:

SERVICES AGREEMENT. Under a services agreement between GTC and Genzyme (the
"Services Agreement"), GTC pays Genzyme a fixed monthly fee for basic laboratory
and administrative support services provided by Genzyme. The monthly fee is
adjusted annually, based on the services to be provided and changes in Genzyme's
cost of providing the services. The Services Agreement is self-renewing annually
and may be terminated upon 90 days notice by either party to the other party.

Lease. GTC leases a portion of Genzyme's facilities in Framingham,
Massachusetts (the "Lease"). GTC paid Genzyme $178,000 under the Lease in 1996.

Credit Line Guaranty, Term Loan Guaranty and Lien. The Company obtained a
credit line in July 1995 and a term loan in December 1995 with a commercial
bank, each secured by Genzyme's guaranty of the Company's obligations thereunder
(up to $9.8 million at December 29, 1996). The Company has agreed to reimburse
Genzyme for any liability Genzyme may incur under such guaranty and has granted
Genzyme a first lien on all of the Company's assets to secure such obligation.

CONVERTIBLE DEBT AGREEMENT. In March 1996, the Company entered into the
Convertible Debt Agreement with Genzyme under which Genzyme agreed to provide a
revolving line of credit in the amount of $10 million. As of December 29, 1996,
$1,673,000 of debt had been converted into 219,565 shares of Common Stock,
leaving $8,327,000 available on the revolving line of credit, which expires on
March 31, 1998. As of December 29, 1996, there was no balance outstanding on the
line of credit.

OTHER STRATEGIC COLLABORATIONS

TUFTS UNIVERSITY SCHOOL OF VETERINARY MEDICINE. Pursuant to a cooperation
and licensing agreement, Tufts has agreed to work exclusively with GTC until
September 1998 in developing commercial applications of transgenic protein
production in milk. Tufts has also granted GTC a perpetual, non-exclusive
license to use certain proprietary microinjection technology and animal
husbandry techniques. Sales of products derived from transgenic goats
produced by Tufts, or from their offspring, are subject to royalties payable
to Tufts. The Company maintains a herd of approximately 150 goats at Tufts'
facility in Grafton, Massachusetts.

The Joint Venture. GTC holds an interest in the Joint Venture which, in
March 1994, increased to 22% after an




additional $1.2 million cash investment by the Company. In October 1995, GTC
contributed approximately $807,000 to maintain its 22% interest. The Joint
Venture and GTC are parties to a research and development agreement under
which the Joint Venture funded GTC's research into transgenic production of
AT-III through October 1995 and certain research on other proteins (the
"Funded Proteins") through October 1996. GTC has granted to the Joint Venture
an exclusive license in Asia to use GTC's transgenic technology to market and
sell transgenic animals and to sell Funded Proteins until the later of 2008 or
the expiration of any applicable Japanese patent, subject to various
reciprocal royalty obligations. In February 1997, the Company reached
agreement with the Joint Venture under which GTC will receive future milestone
payments for the development of AT-III, which, if achieved, could total as
much as $4.4 million (see Note 12 to the consolidated financial statements).

PATENTS AND PROPRIETARY RIGHTS

GTC has filed a number of patent applications which cover relevant portions
of its transgenic technology, several of which are covered by cross-licensing
agreements. GTC holds an exclusive license from Genzyme to rights under a number
of patent applications on file in the United States and corresponding foreign
patent applications relating to certain aspects of its technology. GTC has a
broad patent issued by the European Patent Office which grants the full range of
claims presented in GTC's application covering the basic method of protein
production in milk, as well as any promoter used to do so. Other GTC
applications as to specific proteins, classes of proteins, techniques to enhance
expression and purification technologies remain pending.

GTC has exclusive and nonexclusive licenses to technologies owned by other
parties, including DNX, Inc. as to microinjection, Stanford University as to
gene transfer, and Behringwerke AG as to AT-III, as well as promoter
cross-licenses in place with PPL Therapeutics PLC and Pharming B.V. Certain of
the licenses require GTC to pay royalties on sales of products which may be
derived from or produced using the licensed technology. The licenses generally
extend for the life of any applicable patent. GTC is currently involved in an
arbitration proceeding with Pharming B.V. with respect to one such cross-license
agreement. See "Item 3--Legal Proceedings."

The Company also relies upon trade secrets, know how and continuing
technological advances to develop and maintain its competitive position. In an
effort to maintain the confidentiality and ownership of trade secrets and
proprietary information, the Company requires employees, consultants and certain
collaborators to execute confidentiality and invention assignment agreements
upon commencement of a relationship with the Company.

COMPETITION

TRANSGENICS

Many companies, including biotechnology and pharmaceutical companies, are
actively engaged in seeking efficient methods of producing proteins for
therapeutic or diagnostic applications. Two other companies known to GTC are
extensively engaged in the application of transgenic technology for the
production of proteins: Pharming B.V. and PPL Therapeutics PLC. Pharming B.V.,
based in the Netherlands, is primarily engaged in the development of
recombinant proteins in the milk of transgenic cows, which are most suitable
for extremely high volume protein production. See "Item 3--Legal Proceedings."
PPL Therapeutics PLC, which is based in Scotland, utilizes primarily sheep for
transgenic protein production.

TESTING SERVICES

The worldwide markets for testing services, manufacturing support services
and related development services are highly fragmented, involving several
hundred companies, as well as universities and governmental bodies. Competition
in these markets is based primarily on technological capabilities and reputation
for quality of products and services offered and perceived financial stability.
In certain market segments, price is also a significant competitive factor.

GOVERNMENT REGULATION

TRANSGENICS



The manufacturing and marketing of GTC's potential products, and certain
areas of research related to them, are subject to regulation by governmental
authorities in the United States, including the FDA, the U.S. Department of
Agriculture (the "USDA") and the Environmental Protection Agency (the "EPA").
Comparable authorities are involved in other countries.

To GTC's knowledge, no protein produced in the milk of a transgenic animal
has been submitted for final regulatory approval. However, the FDA issued its
Points to Consider in August 1995. Earlier in 1995 comparable guidelines were
issued by European regulatory authorities. GTC believes that its programs
satisfactorily address the issues raised by these documents and generally views
them as a very positive milestone in the acceptance of the transgenic form of
production. Based on discussions with the FDA and others, GTC expects that the
basic U.S. regulatory framework for the transgenic production of recombinant
proteins in animals will be similar to that described in the Points to Consider.

The anticipated approval process will be a two-part process, governing,
first, the approval of an individual pharmaceutical product as safe and
effective and, second, the approval of the manufacturing process as complying
with applicable FDA current Good Manufacturing Processes ("GMPs"). There can be
no assurance, however, that there will not be any delays in product development
or FDA approval due to issues arising from the breeding of transgenic animals
and the use of proteins derived from such animals.

With respect to therapeutic products generally, the standard FDA approval
process includes preclinical laboratory and animal testing, submission of an IND
to the FDA, appropriate human clinical trails to establish safety and
effectiveness and submission of a New Drug Application prior to market
introduction. The Company generally expects the same process to apply to
transgenically produced products and has already submitted a U.S. IND for AT-III
and has initiated clinical trials in the U.S. GTC expects the approval process
for various proteins to be undertaken either by the Company, by a collaborator
for which the Company is producing proteins, or jointly, depending upon the
nature of the relationship involved.

Approval for the production facilities to be used in producing a therapeutic
product will be subject to both the requirements for Biologics License
Applications and the Points to Consider.

TESTING SERVICES

GTC and its customers are subject to a variety of regulatory requirements
intended to ensure the quality and integrity of their products and services.
The industry standard for conducting non-clinical testing is embodied in
regulations called Good Laboratory Practices ("GLPs"). GLPs have been adopted
by the EPA and the FDA and a number of foreign regulatory bodies. To help
ensure compliance, the Company maintains a strict quality assurance program at
each site to audit test data and conduct regular inspections of testing
procedures and facilities. GTC also complies with FDA-established current Good
Manufacturing Practices ("GMPs") at its Washington Laboratories and at BDL.

GTC also maintains certain licenses and permits issued by federal, state and
local authorities relating to the operation of its current laboratory and
testing facilities, including those required for hazardous waste disposal, the
purchase, use and disposal of radioactive isotopes and the use of animals in
testing and research. These licenses and permits include licenses from the U.S.
Nuclear Regulatory Commission for the purchase, use and disposal of small
amounts of short-lived radioactive isotopes for research purposes. GTC also has
registered with the Massachusetts Department of Environmental Protection and the
EPA as a Very Small Quantity Hazardous Waste Generator in connection with its
disposal of certain organic hazardous wastes used in connection with its
molecular biology and biomedical research. These wastes are disposed of through
a licensed hazardous waste transporter. The use and disposal of chemicals is
regulated under the Toxic Substances Control Act and other state and federal
legislation.

Each of GTC's laboratories is licensed by the USDA and state and local
authorities to house and use laboratory animals for biomedical research
purposes. The ability to continue using animals in testing and research in
dependent on continued compliance with the requirements of such licenses. GTC's
Argus, Mason and Washington Laboratories are also registered with the U.S.
Public Health Service to conduct biomedical research on laboratory animals
funded by the National Institutes for Health ("NIH") and other federal agencies.
GTC's Argus, Mason and Redfield laboratories are also licensed by federal and
state drug enforcement agencies to



procure and use controlled substances in research programs involving
laboratory animals.

The Company's operations are also subject to federal, state and local laws,
rules, regulations and policies governing the use, generation, manufacture,
storage, air emission, effluent discharge, handling and disposal of certain
materials and waste, including, but not limited to, animal waste and waste
water.

RESEARCH AND DEVELOPMENT COSTS

During its fiscal years ended December 29, 1996, December 31, 1995 and
December 31, 1994, GTC spent $8,684,000, $6,394,000, and $4,671,000,
respectively, on research and development. These costs include labor, materials
and supplies, and overhead, the cost of operating the transgenics production
facility, as well as certain subcontracted research projects.

EMPLOYEES

As of December 29, 1996, GTC employed 507 people. Of these, 365 were engaged
in operations, 43 were engaged in research and development, and 99 were engaged
in marketing and general administration. Of GTC's employees, approximately 37
have Ph.D. degrees and 12 have D.V.M. degrees. None of GTC's employees are
covered by collective bargaining agreements. GTC believes its employee relations
are satisfactory.

ITEM 2. PROPERTIES

GTC's headquarters and research facilities are located in approximately
9,100 square feet of laboratory and office space leased from Genzyme in
Framingham, Massachusetts. This lease extends through May 1998, at which time
the lease automatically renews on a year-to-year basis unless terminated by
either party on 90 days' notice. See "Item 1--Business--Relationship with
Genzyme."

GTC owns a 168-acre commercial production facility in central Massachusetts.
This facility contains 48,200 square feet of production, laboratory and
administrative space, as well as a newly completed 7,200 square foot facility
for clinical-grade milk collection and processing. The facility also currently
houses more than 500 goats. GTC believes its and Genzyme's current facilities
are adequate for significant further development of commercial transgenic
products. GTC also currently utilizes animal housing, care and treatment
facilities operated by Tufts in Massachusetts.

GTC ALSO OWNS OR LEASES SITES FOR EACH OF ITS TESTING LABORATORIES. The
Company's Mason Laboratories occupy two facilities in Worcester, Massachusetts,
the largest of which is an approximately 107,600 square foot preclinical testing
facility, leased through March 2005. In addition, GTC owns an adjacent building
that consists of 46,800 square feet, of which 9,400 square feet of space has
been renovated and an additional 18,700 square feet is now being renovated for
preclinical testing. The remaining 18,700 square feet is shell space available
for future expansion.

In addition, GTC owns and occupies a 57,000 square-foot preclinical testing
facility in Redfield, Arkansas; occupies a 37,000 square-foot preclinical
testing facility in Horsham, Pennsylvania, under a lease which expires in June
2002; operates its formulation business in a 10,500 square-foot laboratory
facility in Cambridge, Massachusetts under a lease that expires in October 2002;
and occupies a 20,600 square-foot laboratory and office facility in Rockville,
Maryland, under a lease expiring in December 2000.

The operations of the Company's former subsidiary, Health and Sciences
Research Incorporated ("HSRI") were located in a 20,700 square foot facility in
Englewood, New Jersey under a lease expiring in August 1998. The Company has
sublet approximately 6,000 square feet of this space and is attempting to sublet
the remainder.

ITEM 3. LEGAL PROCEEDINGS

The Company and Pharming B.V. entered into a license agreement (the "License
Agreement") on September 21, 1994, under which the Company and Pharming B.V.
cross-licensed to the other various intellectual property rights under certain
patents relating to the transgenic production of proteins. On December 21, 1995,
Pharming B.V. filed a request for arbitration under the License Agreement,
claiming breach of that agreement on various grounds. The plaintiff is seeking
rescission of the Company's intellectual property rights under the License
Agreement and/or affirmation of Pharming's purported termination of the License
Agreement on July 3, 1996, and unspecified damages. GTC has denied Pharming
B.V.'s allegations and Pharming's authority to terminate the License Agreement
and has filed a counterclaim alleging that Pharming B.V.'s request for
arbitration was filed for improper purposes. While the outcome of the
arbitration proceeding cannot be determined, GTC believes that GTC will be able
to defend this proceeding successfully. There can be no assurance, however, that
GTC will prevail in the defense of the arbitration proceeding. Failure by the
Company to prevail for any reason could have a material adverse effect on the
future operations of the Company, including potential delays in the
commercialization of the Company's transgenic proteins and increased costs.

On June 17, 1994, a lawsuit was filed in the Court of Chancery of the State
of Delaware for New Castle County,



Civil Action No 13569, on behalf of the stockholders of TSI naming the
Company, TSI and each of the directors of TSI as defendants. The complaint
alleges, among other things, that (i) the terms of the merger between TSI and
a subsidiary of GTC pursuant to the Agreement and Plan of Merger dated June
14, 1994 among TSI, GTC and such subsidiary of GTC (the "Merger Agreement")
are unfair to the TSI stockholders, (ii) TSI's directors breached their
fiduciary duties to the TSI stockholders in authorizing TSI to enter into the
Merger Agreement and failing to conduct an auction for TSI, and (iii) GTC
aided and abetted the TSI directors in the breach of their fiduciary duty. The
lawsuit seeks an unspecified amount of damages and a court order to unwind the
Merger. The Company, TSI and the directors of TSI have denied the allegations
set forth in the complaint and intend to vigorously defend the lawsuit. On or
about September 21, 1994, GTC filed a motion to dismiss all claims asserted
against it in the litigation. Plaintiffs have not filed a substantive
opposition to GTC's motion to dismiss, and the motion to dismiss remains
pending before the court.

Except as described above, GTC is not a party to any material legal
proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

During the fourth quarter of fiscal year 1996, no matter was submitted to a
vote of the security holders of the Company.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED

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

YEAR ENDED DECEMBER 29, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

Total revenues for 1996 were $46.8 million compared with $32.4 million in
1995, an increase of $14.4 million or 44%. Service revenues for 1996 were
$38.5 million compared with $26.4 million in 1995, an increase of $12.1
million or 46%. Research and development revenues increased to $8.3 million
in 1996 compared with $6.0 million in 1995, an increase of $2.3 million or
38%, due primarily to an increase in activity and revenues related to the
development of the Company's lead compound, transgenic antithrombin III
("AT-III").

Cost of services for 1996 were $33.9 million compared with $24.3 million in
1995, an increase of $9.6 million or 40%, due to increased service volumes.
Research and development expenses increased to $8.7 million in 1996 compared
with $6.4 million in 1995, an increase of $2.3 million or 36%. The increase
was due to increased activity relating to the development of AT-III, which,
in the second half of 1996, had an Investigational New Drug Filing ("IND")
approved by the Food and Drug Administration ("FDA") and entered into Phase
I/II clinical trials.

Gross profit amounted to $4.2 million in 1996 compared with $1.8 million in
1995. Gross profit on services in 1996 was $4.6 million, a gross margin of
12%, versus $2.1 million, a gross margin of 8% in 1995. The majority of the
improvement in service margins was due to increased service revenues as a
result of continued marketing efforts with an emphasis on developing
significant client relationships and a shift to higher margin services.

Selling, general and administrative ("SG&A") expenses increased to $11.1
million in 1996 from $8.9 million in 1995, an increase of $2.2 million or
25%. The increase was due primarily to increased investment in sales and
marketing and to the growth in the testing services operations.

Interest income increased to $85,000 in 1996 from $32,000 in 1995, an
increase of $53,000 or 166%, primarily due to the investment of funds
received from the Company's 1996 public offering. Interest expense was $1.1
million in 1996 compared with $1.0 million in 1995, an increase of $131,000
or 13%. Of the 1996 total, $902,000 represents interest incurred by the
testing service operations, $167,000 represents interest for the financing of
the transgenic production facility and $61,000 represents interest incurred
under the Convertible Debt and Development Funding Agreement with Genzyme
(the "Genzyme Credit Line") (see Item 8 and Note 5 to the consolidated
financial statements).

The Company recognized $356,000 of Joint Venture losses in 1996 compared to
$713,000 in 1995, a decrease of $357,000 or 50%. The decrease is due to
reduced funding received from the Joint Venture during 1996.

The Company recognized $587,000 of non-operating income in 1996 compared to
$780,000 in 1995, a decrease of $193,000 or 25%. Of the 1996 total, $538,000
represents the collection of the final payments of the promissory note
received in connection with the 1995 sale of the TSI Center for Diagnostic
Products, Inc. ("CDP").

The Company had income from its discontinued clinical operations of $412,000
in 1995. The 1995 income represents the results of operations (net of tax)
for the first three quarters of 1995 for GDRU Limited ("GDRU") and Health and
Sciences Research Incorporated ("HSRI"). These operations were acquired by
the Company as part of the TSI Corporation ("TSI") acquisition in October
1994. GDRU was sold effective as of September 1, 1995 and the HSRI operation
was shutdown in August 1995.

The Company realized a $1,159,000 gain on the disposal of clinical operations
in 1995 from the sale of GDRU.

YEAR ENDED DECEMBER 31, 1995 AS COMPARED TO YEAR ENDED DECEMBER 31, 1994

Total revenues for 1995 were $32.4 million compared with $9.5 million in
1994, an increase of 242%. Service




revenues for 1995 were $26.4 million compared with $4.5 million in 1994, an
increase of 491%. The increase was primarily due to the inclusion of a full
year of TSI operations, compared to one quarter of TSI operations in 1994, as
well as to the inclusion of the operations of BioDevelopment Laboratories,
Inc. ("BDL") for six months in 1995. There were no product revenues in 1995,
compared to $909,000 in 1994, due to the sale of CDP in January 1995.
Research and development revenues increased to $6.0 million in 1995 from $4.1
million in 1994, an increase of 47%, due primarily to an increase in activity
and revenues related to the research and development agreement between the
Company and SMI Genzyme Ltd., a joint venture between the Company and
Sumitomo Metal Industries Ltd. (the "Joint Venture"), and a significant
commercial contract that utilizes the transgenic production facility.

Cost of services for 1995 was $24.3 million compared with $5.2 million in
1994. The increase reflects a full year of the TSI operations in 1995
compared to one quarter in 1994. Due to the sale of CDP, there was no cost of
products in 1995 compared to $841,000 in 1994. Research and development
expenses increased to $6.4 million in 1995 compared to $4.7 million in 1994,
an increase of 37%. The increase reflected a full year of expenses relating
to the operations of the transgenic production facility which began
operations in July 1994. The remainder of the increase in research and
development expenses was due to higher expenditures on the AT-III program
funded by the Joint Venture.

Gross profit amounted to $1.8 million in 1995 versus a loss of $1.2 million
in 1994. Gross profit on services was $2.1 million, a gross margin of 8%,
versus a loss of $692,000 in 1994. The increase in gross profit was due to
higher sales reflecting greater customer confidence in the financial
viability of TSI after the acquisition as well as greater emphasis on
developing significant client relationships.

SG&A expenses increased to $8.9 million in 1995 from $3.6 million in 1994. Of
the 1995 amount, $7.1 million represented the SG&A expenses of TSI for a full
year in 1995 versus $1.8 million for one quarter in 1994, an increase of $5.3
million. The 1995 amount also reflected $1.1 million of goodwill
amortization. Exclusive of TSI and BDL, SG&A expenses remained generally
constant.

Interest income decreased to $32,000 in 1995 from $238,000 in 1994, a
decrease of 87%, primarily due to the use in operations of the funds that
previously were invested. Interest expense was $1.0 million in 1995 compared
to $263,000 in 1994, an increase of 283%. Of the 1995 total, $827,000
represented interest incurred by the testing service operations and $180,000
represented interest incurred on the financing provided by Genzyme
Corporation ("Genzyme") for the construction of the transgenic production
facility.

The Company recognized $713,000 of Joint Venture losses in 1995 compared to
$582,000 in 1994, an increase of 23%. The increase in the loss was due to the
increased research and development activity which the Joint Venture funded
during the period.

The Company recognized $780,000 of non-operating income in 1995 compared to
none in 1994. Of the total, $356,000 represented the Company's portion of the
proceeds from the sale of one of the transgenic animal models owned by
Exemplar Corporation ("Exemplar"), a former customer of TSI, to a third
party. In November 1993, TSI relinquished all rights to Exemplar's transgenic
animal models, subject to the potential to receive a portion of the proceeds
of the sale of any of the models to a third party. The remaining $424,000
represented collection of the first payment of the promissory note received
in connection with the sale of CDP.

Income from discontinued clinical operations was $412,000 in 1995 compared
with $182,000 in 1994. The income represented the results of operations (net
of tax) for GDRU and HSRI. The Company recognized a gain on disposal of
clinical operations in the amount of $1.2 million in 1995. The net gain on
the disposal of GDRU reflected a tax charge of $3.4 million and a write-down
of goodwill identifiable with GDRU of $2.0 million.

NEW ACCOUNTING PRONOUNCEMENTS

The Company adopted the disclosure-only alternative of Statement of
Financial Accounting Standards No. 123 ("SFAS 123"), ACCOUNTING FOR STOCK-BASED
COMPENSATION in 1996. SFAS 123 requires the Company to disclose the pro forma
net income or loss and per share amounts in the notes to the financial
statements using the fair value based method beginning in fiscal 1996 with
comparable disclosure for fiscal 1995.




In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 ("SFAS 128"), EARNINGS PER SHARE.
SFAS 128 specifies the computation, presentation and disclosure requirements
for Earnings Per Share ("EPS"). This statement will be effective for fiscal
year 1997 and will require restatement of all prior period EPS data
presented. Management has not determined the financial impact of adopting
this statement.

LIQUIDITY AND FINANCIAL RESOURCES

At December 29, 1996, the Company had cash and cash equivalents of $8.9
million. During 1996, the Company had a $4.5 million net increase in cash;
$7.1 million of cash was used in operations (due primarily to the net loss of
$7.7 million and an increase in net assets of $4.0 million offset by $4.6
million of non-cash charges), $3.5 million was invested in capital equipment
and further expansion of the transgenic production facility, and $1.7 million
was used to pay down long-term debt. Sources of funds during the period
included net proceeds from the Company's secondary public offering of $12.7
million, $1.7 million of net advances under the Genzyme Credit Line (see
Notes 5 and 10 to the consolidated financial statements) and $1.4 million of
proceeds from the sale of GDRU which were released from escrow during 1996.

In August 1996, the Company completed a public offering of 3,450,000 shares
of Common Stock (the "Offering") providing net proceeds of $12.7 million to
the Company. Subsequent to the Offering, the Company paid down the $1.4
million balance on the Genzyme Credit Line. As of December 29, 1996, no
amounts were outstanding and $8.3 million was available under the Genzyme
Credit Line.

During 1996, the Company received a $2.0 million increase in its lease line
with a commercial leasing company. Leases under the line require monthly
payments over 48-60 months at an annual interest rate of 11% with a fair
market value buyout at the end of the lease term. As of December 29, 1996, $1
million of the increased lease line was utilized and $1 million was available
for use in 1997.

In the fourth quarter of 1996, the Company received a commitment from another
commercial leasing company for $2 million to fund 1997 equipment additions
(see Note 13 to the consolidated financial statements). Leases under this
line will require monthly payments over 48 months at an annual interest rate
of 11% with a fair market value buyout provision at the end of the lease term.

In October 1996, the Company began a $3 million expansion of its Mason
Laboratory facility which is expected to be completed in April 1997. The
Company expects to finance this project through a consortium consisting of
state and local governmental agencies in conjunction with a commercial bank.
Although approval of this financing is anticipated, formal approval has not
been received to date and cannot be assured.

In March 1997, the Company received an extension of the revolving line of
credit ("Credit Agreement") with a commercial bank through March 31, 1999.
Under the agreement, the Company may borrow up to $6 million and $1.5 million
for an existing standby letter in support of a major facility lease. As of
December 29, 1996, the Credit Line was fully drawn and nothing had been drawn
on the standby Letter of Credit. Under the extension, the interest rate on
the Credit Line will be reduced to the Eurodollar rate plus 0.5%.

The Company had a working capital deficit of $116,000 at December 29, 1996,
compared to a deficit of $7.0 million at December 31, 1995. The Company
expects to operate with negative working capital for the foreseeable future.
As of December 29, 1996, the Company had $8.3 million available under the
Genzyme Credit Line and commitments for an additional $3.0 million of capital
lease financing. Under the Company's 1997 operating plan, existing cash
balances, along with funds available under the Genzyme Credit Line and
capital lease lines, are expected to be sufficient to fund the Company
through March 31, 1998.

Management's current expectations regarding the sufficiency of the Company's
cash resources are forward-looking statements and the Company's cash
requirements may vary materially from such expectations. Such forward-looking
statements are dependent on several factors, including the results of the
Company's testing services business, the ability of the Company to enter into
any transgenic research and development collaborations in the future and the
terms of such collaborations, the results of research and development and
preclinical and clinical testing, competitive and technological advances,
regulatory requirements and the Company's ability to complete the financing
for the Mason Laboratory expansion. If the Company experiences




increased losses, the Company may have to seek additional financing through
collaborative arrangements or from public or private sales of its securities,
including equity securities. There can be no assurance that additional
funding will be available on terms acceptable to the Company, if at all. If
additional financing cannot be obtained on acceptable terms, to continue its
operations the Company could be forced to delay, scale back or eliminate
certain of its research and development programs or to enter into license
agreements with third parties for the commercialization of technologies or
products that the Company would otherwise undertake itself.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Genzyme Transgenics Corporation:

We have audited the consolidated balance sheets of Genzyme Transgenics
Corporation as of December 29, 1996 and December 31, 1995 and the related
consolidated statements of operations, cash flows and stockholders' equity for
each of the three fiscal years in the period ended December 29, 1996. 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Genzyme Transgenics Corporation as of December 29, 1996 and December 31, 1995,
and the consolidated results of its operations and its cash flows for each of
the three fiscal years in the period ended December 29, 1996 in conformity with
generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Fiscal Years ended December 29, 1996 and December 31, 1995 and 1994
(all tabular $ in thousands, except per share data)

NOTE 1. NATURE OF BUSINESS

Genzyme Transgenics Corporation (together with its subsidiaries, the
"Company") is engaged in the application of transgenic technology to the
development and production of recombinant proteins for therapeutic and
diagnostic uses and, through its wholly-owned subsidiaries, TSI Corporation
("TSI") and BioDevelopment Laboratories, Inc. ("BDL"), is a leading provider of
preclinical and toxicology testing services to pharmaceutical, biotechnology,
medical device and chemical companies. The accompanying financial statements
have been presented on the assumption that the Company is a going concern. The
Company has incurred losses and negative operating cash flow in each of the
fiscal years ended December 29, 1996 and December 31, 1995 and 1994. The Company
had a working capital deficit of $116,000 at December 29, 1996. The Company
expects to continue to operate with negative working capital for the foreseeable
future. As of December 29, 1996, the Company had $8.3 million available under a
credit line with Genzyme Corporation ("Genzyme") and $1 million under a
commercial equipment lease line. In addition, in February 1997, the Company
entered into a lease agreement with a commercial leasing company for $2 million
of additional lease availability (see Notes 5 and 13).

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, dependence on key personnel,
protection of proprietary technology and compliance with government regulations.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The Company was incorporated in February 1993. On October 1, 1994, the
Company acquired TSI and its respective subsidiaries, Argus Research
Laboratories, Inc. ("Argus"), The TSI Center for Diagnostic Products, Inc.
("CDP"), Health and Sciences Research Incorporated ("HSRI"), TSI Mason
Laboratories, Inc. ("Mason"), TSI Redfield Laboratories, Inc. ("Redfield"), TSI
Washington Laboratories, Inc. ("Washington") and G.D.R.U. Limited ("GDRU"). In
July 1995, the Company acquired BDL.

In August 1995, the Company completed the closure of HSRI. The results of
operations for HSRI are shown net of tax and included in discontinued clinical
operations for all periods presented. Effective September 1, 1995, the Company
completed the sale of GDRU. The results of operations for GDRU are shown net of
tax and included in discontinued clinical operations for all periods presented.
HSRI and GDRU were the only laboratories performing human clinical trials within
the Company's operations.

Genzyme is the Company's largest single stockholder. As a result of various
equity transactions, Genzyme owned 43% and 48% of the Company at December 29,
1996 and December 31, 1995, respectively.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. The Company accounts for its 22% investment
in its Joint Venture using the equity method. All significant intercompany
transactions have been eliminated.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that effect 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. The significant estimates and assumptions in these financial
statements include contract revenue recognition, net realizable value of costs
in excess of net assets acquired and tax valuation reserves. Actual results
could differ from those estimates.



CASH AND CASH EQUIVALENTS

Cash equivalents, consisting principally of money market funds and municipal
notes purchased with initial maturities of three months or less, are valued at
market.

RESTRICTED CASH

Restricted cash represents cash from the sale of GDRU that was held in
escrow and became unrestricted during 1996.

SHORT-TERM INVESTMENTS

All short-term investments are classified as available for sale and are
stated at the lower of cost or market plus accrued interest with premiums and
discounts amortized over the life of the investment. Gains and losses on sales
of securities are calculated using the specific identification method.

During 1994, the Company sold securities with a cost basis of $10,972,000
and realized losses of $70,000 on those sales. At December 31, 1994, short-term
investments consisted of $2,325,000 of corporate notes with remaining maturities
of one to five years. The market value of these investments at December 31,
1994, as of the closing price of the day, was $2,231,000. The unrealized loss on
investments of $94,000 at December 31, 1994 is included in equity.

During 1995, the Company sold securities with a cost basis of $2,231,000 and
realized losses of $108,000 on those sales. At December 29, 1996 and December
31, 1995, there were no short-term investments.

CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash, cash equivalents and trade accounts
receivable. At December 29, 1996, approximately 78% of cash and cash equivalents
were held by one financial institution.

The Company provides most of its testing services to diverse pharmaceutical
companies worldwide. The Company also provides services to the U.S. government.
See Note 9 for additional revenue information. Concentrations of credit risk
with respect to trade receivables are limited due to the large number of
customers comprising the Company's customer base. The Company performs ongoing
credit evaluations of its customers' financial conditions and maintains reserves
for potential credit losses. Activity for fiscal 1996 included a provision of
$334,000, a recovery of $571,000 and write-offs of $144,000.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost and depreciated using
the straight-line method over estimated useful lives of three to thirty
years. Leasehold improvements are amortized using the straight-line method
over the life of the improvement or the remaining term of the lease,
whichever is shorter. The direct costs of the herd of New Zealand goats
("Livestock") and related costs to bring them to the United States were
capitalized and are being amortized using the straight-line method over three
years. The following is the summary of property, plant and equipment and
related accumulated amortization and depreciation as of December 29, 1996 and
December 31, 1995.

Depreciation and amortization expense was $2,603,000, $2,330,000 and
$639,000 for the fiscal years ended December 29, 1996 and December 31, 1995 and
1994, respectively. Accumulated amortization for equipment under capital lease
was $1,311,000 and $741,000 at December 29, 1996 and December 31, 1995,
respectively.

NON CASH TRANSACTIONS

During fiscal 1994, the Company purchased TSI for 4,367,601 shares of stock
valued at $14,741,000 (see Note 3).

During fiscal 1995, the Company purchased BDL for 830,996 shares of stock
valued at $2,386,000 and issued approximately 35,077 shares of stock with a
value of $93,000 in return for settlement of a liability. In connection with the
acquisition, the Company exchanged approximately 341,160 shares of stock with a
value of $976,000 in return for a Consulting and a Non-Competition Agreement
with the principal stockholder of BDL (see Note 3). The Company also purchased
$1,312,000 of fixed assets and financed these additions with capital lease
obligations.

During fiscal 1996, the Company converted $1,673,000 of debt into 219,565
shares of Common Stock under the Convertible Debt and Development Funding
Agreement with Genzyme. The Company also purchased $2,009,000 of fixed assets
and financed these additions with capital lease obligations.

LONG-LIVED ASSETS

The Company adopted Statement of Financial Accounting Standards No. 121
(FAS 121), Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed of, in 1995. FAS 121 requires that
long-lived assets be reviewed for impairment by comparing the cumulative
undiscounted cash flows from the assets with their carrying amount. Any
write-downs are to be treated as permanent reductions in the carrying amount
of the assets. Management's policy regarding long-lived assets is to evaluate
the recoverability of its assets when the facts and circumstances suggest
that these assets may be impaired. This analysis relies on a number of
factors, including operating results, business plans, budgets, economic
projections and changes in management's strategic direction or market
emphasis. The test of such recoverability is a comparison of the asset value
to its expected cumulative net operating cash flow over the remaining life of
the asset.

COSTS IN EXCESS OF NET ASSETS ACQUIRED

The $19,397,000 of excess consideration paid and costs incurred over the net
value of assets acquired (goodwill) by GTC of TSI (see Note 3) is being
amortized using the straight-line method over a twenty-year period. The carrying
value of goodwill is included in management's evaluation of the recoverability
of its long-lived assets. In connection with the sale of GDRU in 1995, goodwill
was written down by $2 million, representing GDRU's percentage of the total
long-term assets acquired in the TSI acquisition, with the charge offsetting a
portion of the gain on disposal of clinical operations. In addition, final
purchase adjustments to goodwill in relation to the purchase of TSI were
recorded which amounted to a net decrease in goodwill of $1,537,000. The
resulting goodwill in connection with the purchase of TSI was $15,860,000.
Accumulated amortization at December 29, 1996 was $1,931,000.

The $7,329,000 of excess consideration paid and costs incurred over the net
fair value of assets of BDL acquired by GTC (see Note 3) is being amortized
using the straight-line method over twenty years. Accumulated amortization at
December 29, 1996 was $563,000.

At December 29, 1996, goodwill totaled $23,189,000 with $2,494,000
accumulated amortization.

ACCRUED EXPENSES

Accrued expenses at December 29, 1996 and December 31, 1995 included the
following:



1996 1995
--------- ---------

Accrued payroll and benefits............................................... $ 1,869 $ 1,624
Accrued severance.......................................................... 219 561
Loss reserves on contracts................................................. 618 1,014
Other...................................................................... 3,205 3,763
--------- ---------
Total accrued expenses.................................................... $ 5,911 $ 6,962
--------- ---------
--------- ---------




As a result of the acquisition of BDL, the Company established severance
reserves of $542,000 for the elimination of 19 positions of which nine were
laboratory positions, three were accounting/finance positions and seven were
general and administrative positions. As of December 29, 1996, $465,000 has been
paid. During 1996, an adjustment of $63,000 was recorded, leaving a balance of
$14,000, which is expected to be paid in 1997.

As a result of the merger with TSI, the Company established severance
reserves for the elimination of 35 positions of which 20 were laboratory
positions, eight were accounting/finance positions and seven were general and
administrative positions. The total severance reserve established was $1,417,000
of which $578,000 was classified as a long-term liability to be paid through
1999. As of December 29, 1996, $898,000 has been paid. Of the remaining $519,000
balance, $314,000 was classified as a long-term liability.

INVESTMENT IN JOINT VENTURE

In 1990, the Company entered into a Joint Venture as a minority owner (see
Note 12). During fiscal years 1992, 1993 and 1994, the Company reduced its
investment in the Joint Venture to reflect impairment in the value of the
investment. In March 1994, the Company made an additional investment of $1.2
million, increasing the Company's ownership percentage in the Joint Venture to
22%, and revised the terms of the Joint Venture R&D Agreement. Accordingly, the
investment has been accounted for under the equity method since the March 1994
investment, and the Company recognizes its share of Joint Venture losses in its
statement of operations. In October 1995, the Company made an additional
investment of $807,000 in the Joint Venture which maintained the Company's
ownership interest at 22%.

REVENUE RECOGNITION AND CONTRACT ACCOUNTING

For both services and research and development revenues, the Company
accounts for cost reimbursement contracts and fixed price contracts using the
percentage of completion method. Unbilled contract revenue represents
recoverable costs and accrued profit which had not been billed at the balance
sheet date. Advance payments represent cash received from customers in advance
of the work being performed. Product revenue is generally recognized upon
shipment. Research and Development revenues in fiscal 1996 consisted of $857,000
from the Joint Venture (see Note 12), $5,949,000 from related parties (see Note
10) and $1,532,000 from commercial clients.

Profits expected to be realized on contracts are based on the total contract
sales value and the Company's estimates of costs at completion. These estimates
are reviewed and revised periodically, throughout the lives of the contracts,
with adjustments to profits resulting from such revisions being recorded on a
cumulative basis in the period in which the revisions are made. When management
believes the cost of completing a contract will exceed its sales value, the full
amount of the anticipated contract loss is immediately recognized.

NET LOSS PER COMMON SHARE

Loss per common share is based solely on the weighted average number of
shares of common stock outstanding as the inclusion of common stock equivalents
would be anti-dilutive. In February 1997, the Financial Accounting Standards
Board issued Statement of Financial Accounting Standards No. 128 ("SFAS 128"),
Earnings Per Share. SFAS 128 specifies the computation presentation, and
disclosure requirements for Earnings Per Share ("EPS"). This statement will be
effective for fiscal year 1997 and will require restatement of all prior period
EPS data presented. Management has not determined the financial impact of
adopting this statement.

INCOME TAXES

The Company has adopted the asset and liability method of accounting for
income taxes as set forth in Statement of Financial Accounting Standards No. 109
("SFAS 109"), Accounting for Income Taxes. Under this method, deferred tax
assets and liabilities are recognized for the expected future tax consequences
of temporary differences between the carrying amounts and the tax bases of
assets and liabilities using the current statutory tax rates.

RECLASSIFICATIONS

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



NOTE 3. ACQUISITIONS/DISPOSITIONS

Effective October 1, 1994, the Company acquired all of the common stock of
TSI, a leading provider of preclinical, toxicology and human clinical testing
services to pharmaceutical, biotechnology, medical device and chemical
companies, for 4,367,601 shares of the Company's common stock with a market
value of approximately $14,741,000 at the date of the acquisition. In exchange
for these shares, the Company received total assets of $20,306,000, assumed
$22,563,000 of liabilities and incurred costs of $2,399,000 with a resulting
goodwill of $19,397,000. The Company has accounted for the acquisition using the
purchase method. Therefore, three months of the operating activities of TSI were
reported in the 1994 Statement of Operations. The following summary represents
the unaudited pro forma results of operations as if the TSI acquisition occurred
at the beginning of 1994. These pro forma results have been prepared for
comparative purposes only and do not purport to be indicative of the results of
operations which would have actually resulted had the combination been in effect
on the date indicated and are not intended to be indicative of future results.

In July 1995, the Company acquired all of the outstanding common stock of
BDL, a leading provider of testing and development services to the
biopharmaceutical, medical device and chemical industries, in exchange for
830,996 of the Company's common shares with an approximate market value of
$2,378,000 at the date of the acquisition. In exchange for these shares, the
Company received total assets with a fair value of $2,595,000, assumed
$6,628,000 of liabilities and incurred costs of $918,000. The transaction was
accounted for under the purchase method and the resulting goodwill of $7,329,000
is being amortized using the straight-line method over 20 years. The Company
also entered into a Consulting and Non-Competition Agreement with the principal
stockholder of BDL in exchange for approximately 341,160 shares of the Company's
common stock with an approximate market value of $976,000. Approximately
$488,000 of the value of the Agreement was assigned to the consulting portion
and was recorded as an expense in 1995. The remaining value, representing the
non-competition portion, was recorded as a long-term asset included in Other
Assets and is being amortized over the ten year non-competition period. As a
part of the transaction, Genzyme exchanged 33,945 shares of its General Division
common stock with a market value of $1,360,000 for 475,467 of the Company's
common shares issued in the transaction.

In August 1995, the Company completed the closure of HSRI, a small clinical
trials monitoring unit based in San Diego, California. The related closure
expenses of approximately $166,000 were recorded in 1995.

Effective September 1, 1995, the Company completed the sale of its GDRU unit
for $9.5 million in cash. In exchange for the cash, the Company sold assets with
a net book value of $2,960,000. The Company recognized a gain on the sale of
$1,159,000 which includes a tax charge of $3,401,000 and a $2,000,000 writedown
of goodwill identifiable with GDRU. In conjunction with this transaction, the
Company received $1,425,000 of restricted cash which became unrestricted in
three increments on January 31, April 30, and September 30, 1996. This
transaction completed the disposition of the former TSI units that were outside
the Company's core preclinical and nonclinical testing operations.

The following summary represents unaudited pro forma results of
operations as if the HSRI and GDRU dispositions and the BDL acquisition had
occurred at the beginning of 1994. These pro forma results have been prepared
for comparative purposes only and do not purport to be indicative of the
results of operations which would have actually resulted had the combination
been in effect on the date indicated and are not intended to be indicative of
future results.

NOTE 4. COMMITMENTS & CONTINGENCIES

The Company leases equipment and facilities under various operating and
capital leases (see Notes 5 and 13). The deferred lease obligation represents
the cumulative difference between actual facility lease payments and lease
expense recognized ratably over the lease period. Rent expense for the fiscal
years ended December 29, 1996 and December 31, 1995 and 1994 was approximately
$2,291,000, $2,553,000, and $528,000, respectively.

At December 29, 1996, the Company's future minimum payments required under
these leases are as follows:

On June 17, 1994, a law suit was filed in the State of Delaware, on behalf
of the stockholders of TSI, naming the Company, TSI and each of the directors of
TSI as defendants. The complaint alleges, among other things, that (i) the terms
of the merger between TSI and a subsidiary of GTC pursuant to the Agreement and
Plan of Merger dated June 14, 1994 among TSI, GTC and such subsidiary of GTC
(the "Merger Agreement") are unfair to the TSI stockholders, (ii) TSI's
directors breached their fiduciary duties to the TSI stockholders in authorizing
TSI to enter into the Merger Agreement and failing to conduct an auction for
TSI, and (iii) GTC aided and abetted the TSI directors in the breach of their
fiduciary duty. The lawsuit seeks an unspecified amount of damages and a court
order to unwind the Merger. The Company, TSI and the directors of TSI have
denied the allegations set forth in the complaint and intend to vigorously
defend the lawsuit. On or about September 21, 1994, GTC filed a motion to
dismiss all claims asserted against it in the litigation. Plaintiffs have not
filed a substantive opposition to GTC's motion to dismiss, and the motion to
dismiss remains pending before the court.

The Company and Pharming B.V. entered into a license agreement (the "License
Agreement") on September 21, 1994, under which the Company and Pharming B.V.
cross-licensed to the other various intellectual property rights under certain
patents relating to the transgenic production of proteins. On
December 21, 1995, Pharming B.V. filed a request for arbitration under the
License Agreement claiming breach of that agreement on various grounds. The
plaintiff is seeking rescission of the Company's intellectual property rights
under the License Agreement, and/or affirmation of Pharming's purported
termination of the License Agreement on July 3, 1996 and unspecified damages.
GTC has denied Pharming B.V.'s allegations and Pharming's authority to terminate
the License Agreement and has filed a counterclaim alleging that Pharming B.V.'s
request for arbitration was filed for improper purposes. While the outcome of
the arbitration proceeding cannot be determined, GTC believes that there is
insufficient ground for rescission of the License Agreement and that GTC will be
able to defend this proceeding successfully. There can be no assurance, however,
that GTC will prevail in the defense of the arbitration proceeding. Failure by
the Company to prevail for any reason could have a material adverse effect on
the future operations of the Company, including potential delays in the
commercialization of the Company's transgenic proteins and increased costs.

NOTE 5. BORROWINGS

Effective July 1, 1994, the Company and Genzyme entered into the Genzyme-GTC
Credit Agreement, pursuant to which Genzyme would provide to GTC advances up to
$6.3 million. The advances accrued interest at the rate of 6% per annum, payable
quarterly. In June 1995, the Company entered into a Common Stock Purchase
Agreement with Genzyme under which the outstanding balance on the Genzyme-GTC
line of credit was reduced by $4 million in exchange for 1,333,333 shares of the
Company's common stock. The remaining balance was repaid in December 1995 and
the line was replaced by a term loan with a commercial bank (described below).



At the date of the TSI acquisition, TSI had certain arrangements with a
commercial bank ("Credit Agreement"). Under the Credit Agreement, TSI could
borrow up to $3 million based on 75% of eligible accounts receivable. In
December 1994, the bank agreed to maintain the maximum borrowing under the
credit line at $3 million. The advances accrued interest at the base rate plus
.5% per annum, payable on the first of the following month. The Company
refinanced the Credit Agreement in July 1995. Under the new facility, which
totals $7.5 million and expires on March 31, 1997, the Company may borrow up to
$6 million and $1.5 million for an existing standby letter of credit in support
of a major facility lease. At the Company's option, interest on loans under the
credit facility (other than the standby letter of credit) shall accrue either at
the Eurodollar rate plus 3/4% or at the bank's base lending rate. The weighted
average interest rate on the line of credit was 7.15% for the fiscal year ended
December 29, 1996 and 9.52% for the fiscal year ended December 31, 1995. As of
December 29, 1996, $6,000,000 was outstanding under the line of credit and none
was available. The Company was in compliance with all covenants and no amounts
were due under the standby letter of credit as of December 29, 1996. Subsequent
to December 29, 1996, the Credit Agreement was extended through March 31, 1999
(see Note 13).

In connection with the refinancing of the Credit Agreement, Genzyme provided
a guaranty to the bank under which Genzyme will become primarily liable under
the Credit Agreement in the event of a default by the Company. In consideration
of Genzyme's agreement to provide such a guaranty, the Company granted a first
lien on all assets of the Company and issued warrants to purchase 145,000 shares
of the Company's common stock for a period of ten years at $2.84375 per share
(market price at the date of the Agreement). Under the terms of the Credit
Agreement, the Company has agreed not to pay any dividends until the loans have
been repaid.

In December 1995, the Company received a $2.3 million term loan from a
commercial bank which matures on December 15, 2000. At the Company's option,
interest on the loan will accrue either at the Eurodollar rate plus 1% or at
the bank's base lending rate. The loan is to be repaid in quarterly
installments commencing March 31, 1997, escalating from $50,000 per quarter
for the first year to $68,750 per quarter in the second year, $91,250 per
quarter for the next year, $133,333 for the final three quarters, and a
balloon payment for the remaining balance due December 15, 2000. The loan is
guaranteed by Genzyme and includes a covenant requiring the Company to
maintain stockholders' equity of at least $20 million. Based on the borrowing
rates currently available to the Company for an unguaranteed loan with a
similar maturity, the fair value of the $2.3 million term loan was $2.2
million.

In June 1995, TSI received a $1 million increase in its lease line with a
commercial leasing company. Leases require monthly payments over 36 months at an
annual interest rate of 11% with a fair market value buyout not to exceed 15% of
original cost at the end of the lease term. The Lease Agreement required a 25%
cash deposit at inception which was reduced to 10% or fully refunded under
certain conditions. In December 1995, the lease line was increased by $1 million
and, during 1996, the lease line was increased by an additional $2 million.
Leases under the increased line require monthly payments over 48-60 months with
a fair market value buyout and no cash deposit. At December 29, 1996, $1 million
was available under the lease line.

In the fourth quarter of 1996, the Company received a commitment for an
additional $2 million in lease line availability from a second leasing company
to fund 1997 capital additions (see Note 13).

On March 28, 1996 the Company entered into a Convertible Debt and
Development Funding Agreement with Genzyme (the'Agreement") under which Genzyme
agreed to provide a revolving line of credit ("Genzyme Credit Line") in the
amount of $10 million and has agreed to fund development costs of the
Antithrombin III ("AT-III") program through March 31, 1997. Under the Agreement,
GTC granted to Genzyme co-marketing rights to AT-III in all territories other
than Asia subject to negotiation and execution of a development and supply
agreement between the parties prior to March 31, 1997. GTC and Genzyme are
currently negotiating the terms of such an agreement. The line of credit carries
a rate of 7% and is convertible into the Company's Common Stock (at the average
market price for the 20-day period ending two days before any conversion), at
GTC's option, to maintain GTC's tangible net worth at the end of each quarter at
a level between $4.0 million and $4.2 million or by Genzyme at any time for up
to the full amount outstanding. Any amount so converted reduces by an equivalent
amount the availability on the line. The line of credit expires on March 31,
1998. During 1996, $1,673,000 of debt was converted into 219,565 shares of
Common Stock, resulting in availability of $8,327,000 on the line of credit. As
of December 29, 1996, there was no balance outstanding on the line of credit.
Interest expense of $61,000 was incurred during 1996 on the line of credit (see
Note 10).



The Company's long-term debt consisted of the following:

Cash paid for interest for the fiscal years ended December 29, 1996 and
December 31, 1995, and 1994 was $1,138,000, $615,000, and $216,000,
respectively.

NOTE 6. STOCKHOLDERS' EQUITY

The Company's authorized capital stock consists of 24,000,000 shares of
common stock, par value $0.01 per share, and 5,000,000 shares of preferred
stock, par value $0.01 per share. Prior to the Company's IPO, the Board of
Directors designated 4,000,000 shares of Preferred Stock as Series A Convertible
Preferred Stock ("Series A Stock"), none of which is outstanding.

In October 1994, the Company acquired TSI for 4,367,601 shares of the
Company's common stock (see Note 3). In addition, all warrants to purchase TSI
Common Stock then outstanding were converted into warrants to purchase the
Company's Common Stock at the acquisition exchange ratio.

In July 1995, Genzyme provided a guarantee of the Company's line of credit
(see Note 5). In consideration for the guarantee, the Company issued warrants to
purchase 145,000 shares of common stock at the then current market price of
$2.84375 per share.

In connection with the commercial lease line, the Company has assumed
warrants to purchase 4,000 shares of Common Stock at a price of $0.10 per share
which were originally issued to the commercial leasing company by TSI in
September 1994. In June 1995, the Company issued additional warrants to purchase
2,000 shares of Common Stock at the then current market price of $2.75 per
share. During fiscal 1996 warrants to purchase an additional 2,000 shares at the
then current market price of $6.50 per share were issued in connection with an
increase in the lease line which was made available in December 1995 (see Note
5).



A summary of the outstanding GTC warrants as of December 29, 1996, all of
which are currently exercisable, is as follows:

In February 1995, Genzyme purchased an additional 500,000 shares of the
Company's Common Stock at $8.00 per share pursuant to the Common Stock Put
Agreement and, in June 1995, Genzyme entered into a Common Stock Purchase
Agreement under which it obtained 1,333,333 shares of the Company's common stock
in exchange for a $4 million reduction in the amount due to Genzyme under the
Genzyme-GTC Credit Agreement (see Note 10). In July 1995, the Company purchased
BDL and entered into a Consulting and Non-Competition Agreement with the
principal stockholder of BDL in exchange for 1,207,233 shares of the Company's
common stock (see Note 3).

In March 1996, Genzyme entered into the Convertible Debt and Development
Funding Agreement (see Note 10) under which it converted $1,673,000 of debt into
219,565 shares of the Company's common stock. In July 1996, the Company
completed a secondary public offering of 3,450,000 shares of its common stock
priced at $4.00 per share. The proceeds to the Company, after deducting
commissions and offering expenses, were $12,700,000.

As of December 29, 1996, the Company has reserved 2,174,745 shares of common
stock, subject to adjustment, for future issuance under the various classes of
warrants, Stock Option and Employee Stock Purchase Plans (see Note 7).

NOTE 7. EMPLOYEE BENEFIT PLANS

STOCK OPTIONS AND PURCHASE PLAN

In May 1993, the Board of Directors adopted and the stockholders approved
the 1993 Equity Incentive Plan (the "Equity Plan"), the 1993 Director Stock
Option Plan (the "Director Plan") and the 1993 Employee Stock Purchase Plan (the
"Purchase Plan").

Under the Equity Plan, 1,290,000 shares of common stock were issued or
reserved for issuance pursuant to incentive stock options, non-statutory stock
options, restricted stock awards, stock appreciation rights or stock units in
accordance with specific provisions to be established by a committee of the
Board of Directors at the time of grant. To date, all options have been issued
at 85% or greater of the fair value at the grant date. The Equity Plan also
permits the Company to assume outstanding options in an acquisition without
using shares reserved under the Plan. Of the foregoing total, 224,350 shares are
subject to options assumed by the Company in the acquisition of TSI. In May
1996, the Board of Directors increased the number of shares reserved for
issuance under this plan to 2,015,000 shares.

Under the Director Plan, 50,000 shares of common stock were reserved for
issuance as non-statutory stock options at the rate of 2,000 shares for each
year of service to members of the Board of Directors who are not employees of
the Company. Such options are automatically granted at fair market value upon
the election or reelection of each director.

Under these plans, an option's maximum term is ten years and vest ratably
20% on the date of issuance and 20% thereafter on the anniversary of the grant.

Under the Purchase Plan, 300,000 shares of common stock were reserved for
the grant of purchase rights to employees in one or more offerings in accordance
with provisions to be established by a committee of the Board of Directors prior
to commencement of any offering period. Participants may purchase shares of
common stock at not less than 85% of the lower of the market value at the
beginning of each offering or on the purchase date. Purchase dates occur every
three months for a period of two years from the offering date. Participants may
not carry over balances from one purchase date to the next. Offering dates occur
every six months. A total of 26,321 and 191,200 shares of common stock remained
available for issuance under the plan at December 29, 1996 and December 31,
1995, respectively. The purchases of common stock under the plan during fiscal
1996 and fiscal 1995 were 164,879 shares at an aggregate purchase price of
approximately $510,000 and 82,199 shares at an aggregate purchase price of
approximately $158,000, respectively. No compensation expense has been recorded
related to the employee stock purchase plan.



In 1996, the Company adopted, Statement of Financial Accounting Standards
No. 123 ("SFAS 123"), Accounting For Stock-Based Compensation. SFAS 123 requires
that companies either recognize compensation expense for grants of stock, stock
options and other equity instruments based on fair value, or provide pro forma
disclosure of net income and earnings per share in the notes to the financial
statements. The Company adopted the disclosure provisions of SFAS 123 in 1996
and has applied APB Opinion 25 and related Interpretations in accounting for its
plans. Accordingly, no compensation cost has been recognized for its stock
option plans. Had compensation cost for the Company's stock-based compensation
plans been determined based on the fair value at the grant dates as calculated
in accordance with SFAS 123, the Company's net loss and earnings per share for
the years ended December 29, 1996 and December 31, 1995 would have been reduced
to the pro forma amounts indicated below:



DECEMBER 29, 1996 DECEMBER 31, 1995
-------------------------------------- -------------------------------
NET LOSS EARNINGS PER SHARE NET LOSS EARNINGS PER SHARE
----------------- ------------------- ----------- ------------------

As Reported........................................... $ (7,746) $ (0.52) $ (4,133) $ (0.35)
Pro Forma............................................. (8,988) (0.61) (4,755) (0.40)


The effects of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts. SFAS 123 does not apply to awards prior to 1995,
and additional awards in future years are anticipated.

A summary of the status of the Company's stock option plans as of December
29, 1996, December 31, 1995 and 1994 and changes during the years ending on
those dates is presented below:

At December 29, 1996, 378,555 shares were available for grant.

The fair value of each stock option is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumption: an expected life of five years, expected volatility of 78%, a
dividend yield of 0% and a risk-free interest rate of 6.49% for fiscal 1996 and
5.92% for fiscal 1995.

The fair value of the employees' purchase rights was estimated using the
Black-Scholes model with a dividend yield of 0%, expected volatility of 78%, a
weighted average risk free interest rate of 5.16% and a weighted average
expected life of six months for fiscal 1996 and a dividend yield of 0%, expected
volatility of 78%, a weighted average risk free interest rate of 6.34% and a
weighted average expected life of one year for fiscal 1995. The weighted average
fair value of those purchase rights granted during fiscal 1996 and fiscal 1995
was $2.08 and $1.09, respectively.

OTHER

All GTC employees, subject to certain eligibility requirements, can
participate in the Company's defined contribution plan. Currently, the Company
may match up to 50% of each participating employee's contributions to the plan
to a maximum of 3% of salary. The Company may also contribute an additional 2%
of each employee's salary as a retirement contribution. All contributions are at
the discretion of the Board of Directors. Expense recognized under this plan was
approximately $368,000, $266,000 and $274,000 for the fiscal years ended
December 29, 1996 and December 31, 1995 and 1994, respectively.

NOTE 8. INCOME TAXES

Income from foreign operations before income taxes in 1996 and 1995 amounted
to approximately $0 and $57,000, respectively.

The income tax provision consists entirely of current amounts. The
components of the income tax provision are as follows:



FISCAL YEARS ENDED

The 1995 tax provision was reflected in operations as a benefit of $2,346,000
offset by a charge of $239,000 to income from discontinued operations and a
charge of $3,401,000 on the gain from the disposal of clinical operations.





The provision for income taxes was at rates different from the U.S. Federal
statutory income tax rate for the following reasons:

The components of the deferred tax assets and liabilities at December 29,
1996 and December 31, 1995, respectively, are as follows:



DECEMBER 29,1996 DECEMBER 31, 1995

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

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


Due to the uncertainty surrounding the realization of these favorable tax
attributes in future income tax returns, the Company has placed a valuation
allowance against its otherwise recognizable deferred tax assets.

At December 29, 1996, the Company had U.S. net operating loss ("NOL")
carryforwards of approximately $50.2 million for federal income tax purposes.
These carryforwards expire through 2011. Utilization of these net operating loss
carryforwards are limited pursuant to provisions Section 382 of the Internal
Revenue Code of 1986, and to the extent that the Separate Return Limitation Year
(SRLY) rules apply.

Approximately $40.6 million of these NOL's were acquired in connection with
its acquisition of TSI. Consequently, any realization of the benefit of these
purchased NOL's will be recorded as a reduction of goodwill. In 1995, goodwill
was reduced by approximately $1 million as a result of the utilization of
purchased NOL's to offset taxable gain principally resulting from the sale of
GDRU.

The Company paid taxes of $27,000, $238,000 and $28,000 in fiscal 1996, 1995
and 1994, respectively.

NOTE 9. REVENUE INFORMATION

Revenues from the U.S. government accounted for 6% of total revenues in
fiscal 1996, 7% in fiscal 1995 and 5% in fiscal 1994. Revenues from the Joint
Venture accounted for 2% of total revenues in fiscal 1996, 12% in fiscal 1995
and 25% in fiscal 1994.

A summary of export sales by fiscal year follows:7

NOTE 10. ARRANGEMENTS WITH GENZYME CORPORATION

From the Company's inception, certain facilities and support services,
including both research and administrative support, have been provided by
Genzyme. For these services, the Company was charged $3,824,000, $3,156,000 and
$2,115,000 for the fiscal years ended December 29, 1996, and December 31, 1995
and 1994, respectively. These charges represent an allocation of the Company's
proportionate share of Genzyme's overhead costs using formulae which management
believes are reasonable based upon the Company's use of the facilities and
services. All other costs for all periods presented, including payroll costs,
are directly attributable to the Company and have been paid by Genzyme and
charged to the Company.

Effective July 1, 1994, the Company and Genzyme entered into the Genzyme-GTC
Credit Agreement (see Note 5), pursuant to which Genzyme agreed to provide GTC
advances up to $6.3 million. The balance of the advance was repaid in December
1995.

In March 1996, the Company entered into a Convertible Debt and Development
Funding Agreement (see Note 5) with Genzyme under which Genzyme agreed to
provide a revolving line of credit ("Genzyme Credit Line") in the amount of $10
million and agreed to fund development costs of the AT-III program. During 1996,
Genzyme converted $1,673,000 of debt to equity under this agreement. There was
$8,327,000 available under the revolving line of credit as of December 29, 1996.
The Company also recognized revenue of $5,875,000 on the AT-III project under
this agreement in 1996.

In April 1993, the Company entered into several agreements under which
Genzyme has agreed to provide various services, facilities and funding to the
Company as described below:

SERVICES AGREEMENT

Under the Services Agreement, the Company receives certain basic support
services in exchange for a fixed monthly payment ($48,469 per month during 1996)
adjusted annually. These basic services include laboratory support, as well as
assistance with certain administrative functions including purchasing, data
processing, risk management, corporate communications, and treasury activities.
If the Company requests additional services from Genzyme, the Company has agreed
to pay Genzyme fully allocated costs of those services. The Services Agreement
is automatically renewed each year thereafter unless terminated by either party
not less than 90 days prior to the end of any annual period. Under the Services
Agreement, the Company made payments of $582,000, $390,000, and $310,000 for the
fiscal years ended December 29, 1996, and December 31, 1995 and 1994,
respectively.

SUBLEASE AGREEMENT

Under the Sublease Agreement, the Company has leased certain laboratory,
research and office space from Genzyme through May 1998 in exchange for fixed
monthly rent payments which approximate the estimated current rental value for
such space. In addition, the Company reimburses Genzyme for its pro rata share
of appropriate facilities operating costs such as maintenance, cleaning,
utilities and real estate taxes. The sublease is automatically renewed each year
and renewals are subject to earlier termination of the sublease by either party
after the initial five-year term. Under the Sublease Agreement, the Company made
payments for the fiscal years ended December 29, 1996, and December 31, 1995 and
1994, of $178,000, $169,000, and $102,000, respectively, and is committed to
make annual minimum rental payments of: $92,400 in 1997 and $53,900 in 1998.

TECHNOLOGY TRANSFER AGREEMENT

Under the Technology Transfer Agreement, Genzyme has transferred
substantially all of its transgenic assets and liabilities to the Company
including its ownership in the Joint Venture, assigned its relevant contracts
and licensed to the Company technology owned or controlled by it and relating to
the production of recombinant proteins in the milk of transgenic animals (the
"Field") and the purification of proteins produced in that manner. The license
is worldwide and royalty free as to Genzyme although the Company is obligated to
Genzyme's licensors for any royalties due them.

As long as Genzyme's ownership of the Company remains below 50%, Genzyme may
use the transferred technology and the new technology only on its own behalf and
without any royalty obligation to the Company.

RESEARCH AND DEVELOPMENT AGREEMENT

In 1993, the Company and Genzyme entered into a Research and Development
Agreement which defines the relationship



among the parties whereby each entity may perform research for the other.
This agreement is in effect through May 1998 and may be renewed by mutual
consent. Genzyme has agreed to use the Company to perform all research in the
field of production of recombinant proteins in transgenic animals. The
Company has a similar obligation to use Genzyme to purify proteins produced
transgenically. Each party must request such services from the other company
before seeking them from a third party although the Company may perform
purification services on its own behalf. These obligations are qualified by
the ability of each party to perform the requested services in accordance
with the performance, scheduling, cost and other specifications reasonably
established by the requesting party. Each company will receive payments from
the other equal to the performing party's fully allocated cost of performing
such services, which shall not be less than 80% of the annual budgets
established by the parties under the agreement, plus, in most cases, a fee
equal to 10% of such costs. The Company currently provides development
services to Genzyme for which it recognized revenues of $75,000, $485,000,
and $883,000 for the fiscal years ended December 29, 1996, and December 31,
1995 and 1994, respectively.

Also, see Note 5.

NOTE 11. OTHER AGREEMENTS

Tufts University School of Veterinary Medicine ("Tufts")

Since 1988, pursuant to a cooperation agreement, the Company has funded an
ongoing program to develop transgenic animals at Tufts. During the term of the
agreement, which extends through September 1998, Tufts has agreed to work
exclusively with the Company for commercial applications within the field of
transgenic protein production in milk. The Company is obligated to make minimum
payments in the aggregate of $266,000 during 1997. The Company paid Tufts
$517,000, $665,000, and $868,000 for the fiscal years ended December 29, 1996,
and December 31, 1995 and 1994, respectively. Sales of products derived from
transgenic goats produced by Tufts, or from their offspring, are subject to
royalties payable to Tufts.

NOTE 12. JOINT VENTURE

In 1990, Genzyme entered into a joint venture with Sumitomo Metal
Industries to develop proteins produced transgenically (the "Joint Venture").
The Joint Venture has engaged the Company, as the successor to Genzyme's
transgenics business, to perform research and development for which the
Company is reimbursed a portion of its costs and receives additional payments
based on achievement of specified milestones. However, GTC does not have any
intercompany profits or losses as a result of its transactions with the Joint
Venture. This three-year program ended during 1993 and the parties decided to
extend the contract for an additional three years. For the fiscal years ended
December 29, 1996, and December 31, 1995 and 1994, the Company recognized
revenue of $857,000, $3,874,000, and $2,947,000, respectively, under this
arrangement. The Company's initial $1,077,000 investment in the Joint Venture
represented a 25% ownership interest. In 1992, the Company invested an
additional $381,000, less than 25% of the aggregate new investment resulting
in a decline of its ownership to 19.7%. In March 1994, the Company and its
partner agreed to extend the Joint Venture contract and contribute an
additional $1.2 million and $4.6 million, respectively, increasing the
Company's ownership percentage to 22%. In October 1995, the Company
contributed an additional $807,000 to maintain the Company's ownership
percentage at 22%. At December 29, 1996, the Company had no advance payments
from the Joint Venture. In February 1997, the Company reached agreement with
the Joint Venture, subject to the approval of the Board of Directors of the
Joint Venture, under which GTC will receive future milestone payments for the
development of AT-III, which, if achieved, could total as much as $4.4
million in revenue.

The Joint Venture has a license, exclusive as to Asia and non-exclusive as
to Europe, to use the Company's transgenic technology and to market and sell
products and transgenic animals produced by the Joint Venture based on that
technology. The Company retained the exclusive right to market and sell such
products within the Americas. Each party is obligated to make royalty payments
based on its sales of products developed by the Joint Venture and, additionally,
the Company is obligated to pay royalties on sales of other transgenically
produced proteins in Asia.

NOTE 13. EVENTS SUBSEQUENT TO THE DATE OF THE REPORT OF INDEPENDENT ACCOUNTANTS

In February 1997, the Company entered into a lease agreement with a
commercial leasing company for $2 million of lease line availability. Leases
under this line will have a term of 48 months at 11% per annum with a fair
market value buyout at expiration.

In March 1997, the Company received an extension of the Credit Agreement
through March 31, 1999. Under the agreement the Company may borrow up to $6
million and $1.5 million for an existing standby letter in support of a major
facility lease.
