                               PROSPECTUS SUMMARY

         The following summary is qualified in its entirety by the more detailed
information and financial statements appearing elsewhere in this Prospectus.
Unless otherwise indicated, the information in this Prospectus assumes that the
Underwriters' over-allotment option will not be exercised. The shares of Common
Stock offered hereby involve a high degree of risk. Investors should carefully
consider the information set forth under the heading "Risk Factors."

                                   THE COMPANY

         Genzyme Transgenics Corporation and its subsidiaries (together, "GTC"
or the "Company") have 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 25 such proteins. For its
lead compound, human recombinant Antithrombin III ("AT-III"), the Company has
achieved clinical grade purity with high recovery levels and has completed
preclinical safety and efficacy studies. GTC is also a leading contract research
organization ("CRO"), providing services such as preclinical efficacy and safety
testing, in vitro testing and formulation development for pharmaceutical,
biotechnology, medical device and other companies. Revenues for the Company's
testing and production services in 1995 were $26.4 million; revenues for the
quarter ended March 31, 1996 were $8.8 million, an increase of 76% above the
same period for 1995.

         GTC produces recombinant proteins transgenically by inserting into the
genetic material of an animal 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. 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
traditional 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. Current worldwide sales of plasma-derived AT-III exceed $200
million annually. 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 traditional methods. GTC has expressed
transgenic AT-III in goats, demonstrating stable expression across two
generations, and has purified it to clinical grade with attractive yields.
Preclinical safety and efficacy studies have been successfully completed and
GTC is preparing an Investigational New Drug Application ("IND") for filing
with the U.S. Food and Drug Administration (the "FDA") to initiate a Phase I
clinical trial for this product.

         Other significant plasma proteins under development by GTC include
Alpha1-protease inhibitor ("API") and human serum albumin ("HSA"). Additionally,
GTC is working with corporate partners on a number of monoclonal antibodies,
including transgenic BR-96, which has potential anti-cancer utility, under an
agreement with Bristol-Myers Squibb Corporation ("Bristol-Myers"). The Company
is also developing transgenic production processes for other proteins including
prolactin, insulin and a protein for a malaria vaccine.

         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 an October
1992 issue of The New England Journal of Medicine and the May 1995 issue of The
Lancet. GTC expects to produce vaccines for approximately 20 patients in 1996.

                                  RISK FACTORS

         An investment in the shares of Common Stock being offered hereby
involves a high degree of risk. Prospective investors should carefully consider
the following risk factors, in addition to the other information contained in
this Prospectus, before purchasing the shares of Common Stock offered hereby.

         HISTORY OF OPERATING LOSSES; NEED FOR ADDITIONAL FUNDS. GTC has had
operating losses since its inception and expects such losses to continue for the
next several years. For the period from its inception in 1993 to March 31, 1996,
the Company incurred cumulative losses of approximately $12.1 million. GTC's
losses have resulted principally from costs incurred in connection with research
activities and from expenses in excess of revenues from the Company's CRO
services. GTC's sources of revenues to date have consisted primarily of research
and development contracts and CRO services. Such revenues to date have not been
sufficient to generate profits. The Company expects to continue to incur
significant operating losses until such time as product sales and CRO service
revenues are sufficient to fund its operations. No assurance can be given that
the Company will become profitable.

         The Company currently believes that existing cash resources, available
financing and the proceeds from this offering will be sufficient to meet its
operating cash flow needs and capital requirements at least through the end of
1997. The development of transgenic products by the Company will require the
commitment of substantial resources to conduct costly and time-consuming
research, preclinical testing and clinical trials necessary to bring such
products to market. If GTC's businesses do not achieve profitable operations at
or prior to the time such existing resources are exhausted, the Company will
need to obtain additional financing, through public or private financings,
including debt or equity financings, or through collaborative or other
arrangements with corporate partners, as appropriate. Adequate funds for the
Company's operations from such sources may not be available when needed or on
terms acceptable to the Company. If additional financing cannot be obtained when
needed or on acceptable terms, GTC could be forced to delay, scale back or
eliminate certain of its research and development programs or to license to
other parties rights to commercialize products or technologies that the Company
would otherwise seek to develop internally as well as delaying or forgoing
timely expansion, improvement or investment in the Company's contract research
services. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations-Liquidity and Capital Resources."

         The foregoing forward-looking statements regarding the Company's
expectations of the need for additional funds are subject to risks and
uncertainties. The Company's cash requirements may vary materially from those
now planned depending upon the results of existing businesses, the terms of
future collaborations, results of research and development, competitive and
technological advances, regulatory requirements and other factors.

         EARLY STAGE OF TRANSGENIC TECHNOLOGY. Development of products based on
transgenic technology is subject to a number of significant technological risks
and the time period required for any such development is both lengthy and
uncertain. Neither GTC nor, to GTC's knowledge, any other entity has conducted
human clinical trials of any protein produced in the milk of transgenic animals
and there can be no assurance that GTC will be able to do so successfully. There
can be no assurance that any transgenically produced protein will be safe or
effective. All of the proteins that GTC is developing will require significant
additional research, development and testing and will require the expenditure of
substantial additional capital prior to their commercialization. In addition,
there can be no assurance that research and discoveries by others will not
render GTC's technology obsolete or noncompetitive.

         NO ASSURANCE OF COMMERCIAL SUCCESS OF TRANSGENIC PRODUCTS. The
successful commercialization of any transgenic protein product by the Company
will depend on many factors, including the successful completion of clinical
testing, the response of medical professionals to the data from clinical trials,
the Company's ability to create or access a sales force able to market such
transgenic products, the Company's ability to supply a sufficient amount of
product to meet market demand, the degree to which third-party reimbursement for
use of such product is available and the number and relative efficacy of
competitive products that may subsequently enter the market, as well as, with
respect to transgenic products designed to replace or supplement products
currently being marketed, the relative cost-effectiveness of the transgenic
products. There can be no assurance that the Company or its collaborative
partners will be successful in efforts to develop and implement a
commercialization strategy for any such products.

         GTC does not currently have a sales force to market any transgenic
products it may develop. The Company anticipates that for products it develops
independently it will enter into marketing arrangements with larger
pharmaceutical or biotechnology companies which have established sales forces
able to market such products. There

                                      - 8 -

<PAGE>   9



can be no assurance that any marketing or distribution arrangements will be
available on acceptable terms or that, in the alternative, GTC will be able to
establish its own sales force successfully. Unforeseen delays in this process
may have an adverse effect on the commercialization of any of the Company's
products.

         Third-party payors are increasingly attempting to contain health care
costs by limiting both coverage and the level of reimbursement for new
therapeutic products. The successful commercialization of any products
developed by the Company may depend on obtaining coverage and reimbursement
for the use of these products from third-party payors.

         In addition, the successful commercialization of the Company's products
will require that medical professionals become convinced of the efficacy of the
products in treating a particular condition and incorporate such products as
standard practice in relevant therapeutic protocols. There can be no assurance
that any transgenic product developed by GTC will be accepted by the medical
profession.

         GOVERNMENT REGULATION. Transgenic products will require approval by the
FDA prior to marketing in the United States. In addition, the manufacturing and
marketing of such products, and certain areas of research related to them,
are subject to regulations by other U.S. governmental authorities including
the United States Department of Agriculture (the "USDA") and the Environmental
Protection Agency (the "EPA"). Comparable authorities are involved in other
countries.

         In cases where the Company expects to obtain revenue from the sale of
transgenic products, whether through direct sales, marketing relationships with
others or royalty arrangements, the Company will incur the risk of such product
failing to satisfy applicable regulatory requirements prior to marketing. The
approval process involves two parts, 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 practices regulations ("GMPs"). In 1995, the FDA and comparable
European regulatory authorities issued guidelines regarding the production of
therapeutic proteins in transgenic animals. While the FDA's guidelines, known as
Points to Consider guidelines ("Points to Consider"), cover issues specific to
transgenic production, the basic regulatory framework for FDA approval will also
apply to transgenic therapeutic products submitted for approval. To GTC's
knowledge, no protein produced in the milk of a transgenic animal has been
submitted for regulatory approval in the United States or elsewhere.

         The FDA and comparable agencies in foreign countries impose substantial
requirements upon the introduction of therapeutic pharmaceutical products
through lengthy and detailed laboratory and clinical testing procedures,
sampling activities and other costly and time-consuming procedures. Satisfaction
of these requirements typically takes several years or more and can vary
substantially based upon the type, complexity and novelty of the product. With
respect to therapeutic products, the standard FDA approval process includes
preclinical laboratory and animal testing, submission of an IND to the FDA,
appropriate human clinical trials to establish safety and effectiveness and
submission of a New Drug Application ("NDA") prior to market introduction. With
respect to obtaining approval for the production facilities to be used in
producing a therapeutic product, the Company expects to be subject to both the
requirements for establishment license applications and the Points to Consider
issued with respect to transgenic recombinant products.

         The effect of government regulation may be to delay marketing of the
Company's products for a considerable or indefinite period of time, impose
costly procedural requirements upon the Company's activities and may furnish a
competitive advantage to larger companies or companies more experienced in
regulatory affairs. There can be no assurance that FDA or other regulatory
approvals for any products developed by the Company will be granted on a timely
basis or at all. Any delay in obtaining or any failure to obtain such approvals
could adversely affect the Company's ability to generate revenue. Even if
initial regulatory approvals for the Company's product candidates are obtained,
the Company, its products and its transgenic manufacturing processes would be
subject to continual review and periodic inspection. There can be no assurance
that the FDA will permit the marketing of any transgenic product for any
particular indication, if at all.

         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. See "Business-Government Regulation."

         DEPENDENCE OF TESTING SERVICES ON CURRENT GOVERNMENT REGULATORY
REQUIREMENTS. The market for GTC's preclinical testing services is dependent
upon the maintenance of strict standards for the conduct of laboratory and


                                      - 9 -

<PAGE>   10



clinical tests and related procedures which are promulgated by governmental
entities responsible for public health and welfare, including the FDA, and by
regulatory authorities in foreign countries. The process of obtaining these
approvals varies according to the nature and use of the product and routinely
involves lengthy and detailed laboratory and clinical testing and other costly
and time-consuming procedures. The Company offers the customers of its
preclinical testing and development services the necessary expertise to comply
with these complex regulations. If the regulatory structure were to change in a
way which reduced the need for such services, the Company could be materially
adversely affected.

         DEPENDENCE ON GENZYME. GTC has entered into a number of contractual
agreements with Genzyme, including a research and development agreement pursuant
to which Genzyme provides purification services to GTC for transgenically
produced proteins (the "Genzyme R&D Agreement"), a lease of GTC's facility in
Framingham, Massachusetts, and an agreement to fund the development of AT-III
through the first quarter of 1997. See "Business-Relationship with Genzyme."

         Under the Genzyme R&D Agreement, Genzyme is obligated to use
commercially reasonable efforts to perform purification services for GTC. GTC
does not currently have personnel capable of undertaking such purification
services. Until such time, if ever, as GTC develops its own capabilities in this
regard, there can be no assurance that Genzyme will be able to provide such
services when and as required by GTC or that GTC would be able to obtain
comparable services elsewhere.

         There can be no assurance that Genzyme and GTC will reach agreement to
extend Genzyme's funding of the AT-III development program beyond the first
quarter of 1997 under terms attractive to GTC, if at all. There also can be no
assurance that, in the absence of such agreement, the Company will be able to
fund such program on its own beyond the end of 1997 or that the Company will
be able to obtain such funding from a third party on acceptable terms, if at
all.

         POTENTIAL CONFLICTS OF INTEREST WITH GENZYME. After giving effect to
this offering, Genzyme will remain the largest single stockholder of GTC with
approximately 40% of the outstanding Common Stock, assuming exercise of a
currently exercisable warrant for 145,000 shares of Common Stock and issuance of
additional shares of Common Stock on conversion of outstanding indebtedness of
the Company held by Genzyme under the terms of a Convertible Debt and
Development Funding Agreement (the "Convertible Debt Agreement") at June 30,
1996. See "Business-Relationship with Genzyme" and "Share Ownership."

         Genzyme's ownership interest gives it significant influence over any
election of directors and any other action requiring approval by the holders of
a majority of the Common Stock. Three members of GTC's Board of Directors,
including Henri Termeer, the Chairman of the Board of the Company, also serve as
directors and/or executive officers of Genzyme. The interests of Genzyme on the
one hand and GTC on the other hand may, from time to time, differ.

         DEPENDENCE ON COLLABORATORS. The success of GTC's transgenic protein
production business will depend, in large part, on GTC's ability to enter into
arrangements with biotechnology and pharmaceutical companies for the transgenic
production of proteins to which such companies have proprietary rights or to
fund the development of transgenic proteins which are in the public domain or
the subject of expiring patents. To date, the scope of these agreements has
generally been limited to demonstrating the feasibility of transgenic production
of targeted proteins in particular animal species. There can be no assurance
that these feasibility studies will be successful or lead to agreements for the
commercial production of any proteins. Depending upon the terms of any future
collaborations, the Company's role in such collaborations may be limited to the
production aspects of the proteins under development. As a result, GTC may also
be dependent on collaborators for other aspects of the development, preclinical
and clinical testing, regulatory approval and commercialization of any
transgenic product.

         UNCERTAINTY REGARDING PATENTS AND PROPRIETARY TECHNOLOGY. GTC has
relied upon trade secrets, proprietary know-how and continuing technological
innovation to develop and maintain its competitive position and to protect its
proprietary technology. In part, these legal rights are protected by contracts
with employees, consultants and business partners. There can be no assurance
that trade secrets possessed by GTC will be maintained, that secrecy obligations
will be honored or that others will not independently develop similar or
superior technology. There is no assurance that patent applications filed by GTC
will result in patents being issued or that any patents issued to or licensed by
GTC will be held valid. The Company may also be subject to claims that result in
the revocation of patent rights previously licensed to GTC as a result of which
the Company may be required to obtain licenses from others to continue to
develop, test or commercialize its products. There can be no assurance that GTC
will be able to obtain such licenses on acceptable terms, if at all. In
addition, there may be pending or issued patents held by parties not affiliated
with GTC that relate to the technology utilized by GTC. As a result,

                                     - 10 -

<PAGE>   11



GTC may need to acquire licenses to, or contest the validity of, such patents or
any other similar patents which may be issued. GTC could incur substantial costs
in defending itself against challenges to patent or infringement claims made by
third parties or in enforcing any patent rights of its own. The loss or exposure
of trade secrets possessed by GTC could also adversely affect its business.

         On December 21, 1995, Pharming B.V. filed a request for arbitration
under a cross-license agreement with GTC granting various patent rights relating
to the transgenic production of proteins seeking, among other things, a
declaratory judgment which would effectively rescind the agreement. 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 successfully defend this proceeding. 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 Company, including potential delays in the
commercialization of the Company's transgenic products and increased costs. See
"Business-Legal Proceedings."

         COMPETITION. The industries in which GTC operates are highly
competitive and may become even more competitive. It will be necessary for GTC
to continue to devote substantial efforts and expense to research, development,
sales and marketing in order to maintain a competitive position. There can be no
assurance that developments by others will not render its current and proposed
services, products or technologies obsolete. In addition, GTC may encounter
significant competition for protein development and production contracts from
other companies. Transgenic products may face significant competition from
biological products manufactured in cell culture or derived from human serum or
tissue or animal serum or tissue. GTC's business will compete both against other
companies whose business is dedicated to offering transgenic production or
preclinical testing and development as a service and with prospective customers
or collaborators who decide to pursue such transgenic production or preclinical
testing and development internally.

         RISK OF SERVICE OR PRODUCT LIABILITY. GTC's business exposes it to
potential product and professional liability risks which are inherent in the
testing, production, marketing and sale of human therapeutic products. While GTC
has obtained product and professional liability insurance under an insurance
policy arrangement with Genzyme and Genzyme's affiliates, there can be no
assurance that such insurance will be sufficient to cover any claim. See
"Business-Relationship with Genzyme." Uninsured product or service liability
could have a material adverse effect on the financial results of GTC. In
addition, there can be no assurance that any insurance will provide GTC with
adequate protection against potential liabilities. Potential liability also may
arise from the handling by GTC of clinical samples containing human blood and
tissues, which may contain human pathogens; liability may also arise from
handling animal blood and tissue which may contain zoonotic pathogens. Although
such products are used only in the laboratory, inadvertent human contact may
occur.

         RETENTION OF KEY PERSONNEL. Although GTC believes that the size and
qualifications of its current staff are adequate for its current business, the
Company must continue to attract and retain qualified scientific, technical,
marketing and management personnel as its business expands. There is intense
competition for qualified personnel in the areas of the Company's activities,
and there can be no assurance that GTC will be able to continue to attract and
retain the qualified personnel necessary for the development of its business.
Loss of the services of, or failure to recruit, key scientific and technical
personnel could have a material adverse effect on GTC's business.

         PUBLIC CONCERNS. Certain of GTC's activities involve animal testing and
genetic engineering in animals. Such activities have been the subject of
controversy and adverse publicity. Animal rights groups and various other
organizations and individuals have attempted to stop animal testing and genetic
engineering activities by pressing for legislation and regulation in these
areas. To the extent the activities of such groups are successful, GTC's
business may be adversely affected.

         SHARES ELIGIBLE FOR FUTURE SALE. Sales of substantial amounts of Common
Stock in the public market, or the perception that such sales may occur, could
adversely affect the prevailing market price of the Common Stock. As of May 31,
1996, there were 13,338,406 shares of Common Stock outstanding. As of May 31,
1996, options to purchase an aggregate of 1,511,310 shares of Common Stock at
varying exercise prices were outstanding; of such total, options for 655,249
shares were immediately exercisable and such shares could be immediately resold
into the public market. An additional 190,600 shares of Common Stock are
reserved for issuance upon exercise of outstanding warrants. Of the 6,335,044
shares held by Genzyme, 4,000,000 could be sold into the public markets upon
compliance with Rule 144. See "Shares Eligible for Future Sale." In addition,
all other shares held by Genzyme and those issuable to Genzyme upon exercise of
an outstanding warrant are entitled to registration rights which could expedite
the resale of such shares into the public market. Genzyme, the directors,
officers and certain

                                     - 11 -

employees of GTC have agreed not to dispose of their shares for a period of 90
days (180 days in the case of Genzyme) after the effective date of this
offering. See "Description of Capital Stock" and "Shares Eligible for Future
Sale."

         POSSIBLE VOLATILITY OF STOCK PRICE; ABSENCE OF DIVIDENDS. There has
been a history of significant volatility in the market prices of publicly-traded
common stock of companies engaged in applications of biotechnology, including
the Company, and the market price of the Common Stock has been and may continue
to be highly volatile. Announcements of technological innovations or new
products by GTC or others, developments or disputes concerning patents or
proprietary rights, publicity regarding actual or potential medical results
relating to products under development by GTC or its competitors, regulatory
developments, period-to-period fluctuations in GTC's financial results and
general economic and market conditions, among other things, may have a
significant impact on the market price of the Common Stock. GTC has not paid any
dividends since its inception and does not intend to pay any dividends in the
foreseeable future.

         CHANGE IN CONTROL. Certain provisions of Massachusetts law and of GTC's
charter documents could have the effect of discouraging others from attempting
hostile takeovers of GTC. Such provisions may also have the effect of preventing
changes in the management of GTC. It is possible that such provisions could make
it more difficult to accomplish transactions which stockholders may deem to be
in their best interests. See "Description of Capital Stock-Anti-Takeover
Measures."

         DILUTION. Purchasers of Common Stock offered hereby will experience an
immediate and substantial dilution in net book value of $6.486 per share. At May
31, 1996, there were options outstanding to purchase an aggregate of up to
1,511,310 shares of Common Stock at exercise prices between $2.75 and $55.00 per
share. GTC also has outstanding warrants to purchase 190,600 shares of Common
Stock at exercise prices between $0.05 and $6.50 per share. The exercise of
these options and warrants will result in further dilution to investors in this
offering. See "Dilution," "Shares Eligible for Future Sale" and "Description of
Capital Stock."

                                 USE OF PROCEEDS

         The net proceeds from the sale of the Common Stock offered hereby are
estimated to be $22.6 million ($26.0 million if the Underwriters' over-allotment
option is exercised in full), assuming a public offering price of $8.125 per
share and after deducting underwriting discounts and estimated commissions and
offering expenses.

         The net proceeds of this offering, together with the Company's existing
cash, cash equivalents, short-term investments and cash generated from
operations are expected to be used for the following purposes: (i) to repay
outstanding indebtedness to Genzyme in an amount of approximately $1.4 million
pursuant to a line of credit, under which the outstanding balance accrues
interest at a rate of 7.0% per annum, that will terminate upon completion of
this offering, (ii) to fund research and product development programs, including
the anticipated clinical trials of AT-III (to the extent not funded by Genzyme
or others) and the development of idiotypic vaccines for the NCI and (iii) for
general corporate purposes and working capital. Such general corporate purposes
may include acquisitions of other businesses, technologies, product rights or
distribution rights.

         The timing and amount of funds required for all specific uses of the
proceeds from this offering cannot be precisely determined by the Company at
this time. The rate of the Company's progress in developing transgenic products,
the timing and nature of regulatory action, economic and regulatory factors
affecting the contract research industry as a whole and the availability of
alternative methods of financing, including collaborative agreements with other
companies relating to the development, manufacture and marketing of transgenic
products, will also affect the Company's allocation of the net proceeds from
this offering and the timing thereof.

         The Company currently believes that its existing capital resources
(exclusive of the terminating Genzyme line of credit), together with the
proceeds of this offering and interest thereon, plus anticipated revenues from
CRO operations and research funding currently obligated from corporate
partners, will enable the Company to maintain its current and planned operations
at least through the end of 1997. The foregoing forward-looking statements
regarding the Company's expectations of the need for additional funds are
subject to risks and uncertainties. The Company's cash requirements may vary
materially from those now planned depending upon the results of existing
businesses, the terms of future collaborations, results of research and
development, competitive and technological advances, regulatory requirements and
other factors. See "Business-Relationship with Genzyme."

         Pending use, the net proceeds will be invested in interest-bearing,
investment grade securities. The Company intends to invest and use such proceeds
so as not to be considered an "investment company" under the Investment Company
Act of 1940, as amended.

                                    DILUTION

         The net tangible book value of the Company as of March 31, 1996 was
$4,150,000, or $0.312 per share. Net tangible book value per share represents
the total tangible assets of the Company, less total liabilities, divided by the
total number of shares of Common Stock outstanding. Assuming the receipt by the
Company of the net proceeds from the sale of the 3,000,000 shares of Common
Stock offered hereby at an assumed public offering price of $8.125 per share,
the pro forma net tangible book value of the Company as of June 7, 1996 would
have been $26,702,500, or $1.639 per share. This represents an immediate
increase in the pro forma net tangible book value of $1.327 per share to
existing stockholders of the Company and an immediate dilution of $6.486 per
share to new investors purchasing Common Stock in this offering.

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

OVERVIEW

         The Company was incorporated as a wholly-owned subsidiary of Genzyme in
February 1993. In May 1993, Genzyme entered into a stock purchase agreement
under which Genzyme purchased four million shares of GTC's Series A Convertible
Preferred Stock in exchange for the transfer of substantially all of the assets
and liabilities of Genzyme's transgenics business unit to the Company. As part
of this transaction, the Company and Genzyme entered into a Technology Transfer
Agreement (the "Technology Transfer Agreement"), the Genzyme R&D Agreement and
certain sublease and service agreements. Upon completion of the Company's
initial public offering in July 1993, Genzyme owned approximately 73% of the
Company. Through subsequent equity transactions, Genzyme's ownership declined to
approximately 49%.

         In October 1994, the Company acquired all of the outstanding common
stock of TSI Corporation ("TSI") in exchange for 4,367,601 shares of Common
Stock with an approximate market value of $14 million at the transaction date.
This acquisition was undertaken in order to expand the Company's business
operations and to provide a more comprehensive offering of support services to
its customers. The Company further expanded its non-clinical capabilities in
July 1995 with the acquisition of BioDevelopment Laboratories, Inc. ("BDL") for
approximately 831,000 shares of Common Stock with an approximate market value at
the time of $2.6 million. Also in 1995, the Company refocused the testing
operations toward the non-clinical area with the closure of Health and Sciences
Research Incorporated ("HSRI"), a small clinical trials monitoring unit, and the
disposition of GDRU Limited ("GDRU"), a London-based Phase I clinical trials
unit, for approximately $9.5 million in cash. In January 1995, the Company sold
its diagnostics products business, The TSI Center for Diagnostics Products, Inc.
("CDP"), which was acquired as part of TSI, for $822,550 in cash and a note
receivable in the amount of $1.1 million.

RESULTS OF OPERATIONS

First Quarter Ended March 31, 1996 as Compared to First Quarter Ended March 31,
1995

         Total revenues for the first quarter of 1996 were $10.4 million,
compared with $6.1 million in the comparable period of 1995, an increase of 69%.
Of the increase, $999,000 represents service revenue derived from the operations
of BDL. Exclusive of the BDL acquisition, service revenues increased 56%.
Revenues from continuing service operations have grown in each quarter following
the acquisition of TSI, from $4.5 million in the fourth quarter of 1994 to $8.8
million in the first quarter of 1996, a cumulative growth of 97%, and
year-to-year growth of 76% over the first quarter of 1995. Research and
development revenues increased to $1.6 million in the first quarter of 1996 from
$1.1 million in the first quarter of 1995, an increase of 40%, due primarily to
an increase in activity and revenues related to the funding received in the
development of AT-III.

         Cost of services for the first quarter of 1996 was $7.6 million
compared with $5.0 million in the first quarter of 1995, an increase of 54%. Of
the increase, $728,000 represents cost of services derived from the operations
of BDL. Exclusive of the BDL acquisition, cost of services increased $1.9
million, or 39%. Research and development expenses increased to $2.0 million in
the first quarter of 1996 from $1.6 million in the first quarter of 1995, an
increase of 26%. The increase is due to increased activity in research programs.

         Gross profit for the first quarter of 1996 was $745,000 versus a loss
of $410,000 in the first quarter of 1995. Gross profit on services for the first
quarter of 1996 was $1.2 million, a gross margin of 13%, versus $53,000, a gross
margin of 1%, in the first quarter of 1995. Gross profit from continuing service
operations has grown each quarter since the acquisition of TSI in October 1994.

         Selling, general and administrative ("SG&A") expenses increased to $2.6
million in the first quarter of 1996 from $2.1 million in the first quarter of
1995, an increase of 25%. Of the increase, $245,000 represents SG&A expenses of
BDL, including $106,000 of goodwill amortization related to the BDL acquisition.
Exclusive of BDL, SG&A expenses increased by $267,000, or 13%.

         Interest income decreased to $8,000 in the first quarter of 1996 from
$10,000 in the first quarter of 1995, due to a reduction in funds available for
investment. Interest expense increased to $310,000 in the first quarter of 1996
from $258,000 in the first quarter of 1995. Of the 1996 total, $255,000
represents interest expense incurred under a line of credit with a commercial
bank and other financial obligations related to the testing operations.

                                     - 18 -

         The Company recognized $40,000 of losses attributable to GTC's joint
venture with Sumitomo Metals Industries, Ltd. (the "Joint Venture") during the
first quarter of 1996 compared to $163,000 in the first quarter of 1995. The
decrease in the loss is due to the decreased research and development activity
which the Joint Venture funded during the period.

         The Company realized no income from its discontinued clinical
operations in the first quarter of 1996 compared to $255,000 in the first
quarter of 1995. The 1995 income from discontinued clinical operations
represents the results of operations (net of tax) for the first quarter of 1995
for GDRU and HSRI. The Company received $318,000 of non-operating income in the
first quarter of 1996 which represented the second payment of the promissory
note received in connection with the sale of CDP. Due to uncertainties
surrounding recovery of the note, 90% of the value of the promissory note was
reserved and will be recognized as income as payments are received.

Testing Service Operating Performance - Six Quarters Ended March 31, 1996

         The following is a summary of the operating performance of the
Company's continuing testing service operations in the six quarters since the
acquisition of TSI (all dollar amounts in thousands):

</TABLE>


 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 is
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 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 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. There was no cost of products in 1995 compared
to $841,000 in 1994 due to the sale of CDP. Research and development expenses
increased to $6.4 million in 1995 compared to $4.7 million in 1994, an increase
of 37%. The increase reflects 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 $1.8 million in 1995 compared to
$263,000 in 1994, an increase of 283%. Of the total, $827,000 represented
interest incurred by the testing service operations and $180,000 represented
interest incurred on the financing provided by 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. 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.

 Year Ended December 31, 1994 as Compared to Year Ended December 31, 1993

         The 1994 results include the results of operations of TSI from the date
of acquisition (October 1, 1994), adjusted for the reclassification of the
discontinued operations.

         Total revenues for 1994 were $9.5 million, compared with $3.2 million
in 1993, an increase of 194%. Of the increase, $4.5 million represented service
revenues derived from the operations of TSI. Additionally, $909,000 of the
increase represented product revenues derived from CDP from the date of the TSI
acquisition. Research and development revenues increased to $4.1 million in 1994
from $3.2 million in 1993, an increase of 27%, due primarily to an increase in
activity and revenues related to the research and development agreement between
the Company and the Joint Venture.

         Cost of services of $5.2 million in 1994 were derived from the
operations of TSI. Cost of products of $841,000 in 1994 was derived from the
operations of CDP. Research and development expenses increased to $4.7 million
in 1994 from $3.1 million in 1993, an increase of 49%. The increase included
approximately $459,000 of expenses related to the development of the transgenic
production facility which began operating in July 1994. The remainder of the
increase in research and development expense was due to an increase in the
number of research programs as well as an increase in expenditures on the AT-III
program.

         Gross profit was a loss of $1.2 million in 1994 versus a profit of
$79,000 in 1993, a decrease of $1.3 million. Gross profit on services was a loss
of $692,000 in 1994 representing the operations of TSI for the fourth quarter.
The low margin was due to a reduced level of testing service revenues during
that period resulting from a number of factors, including: 1) potential
customers' perception that TSI's financial position was unstable prior to the
acquisition, 2) TSI's inability to invest in sales and marketing programs due to
cash flow constraints prior to the acquisition and 3) a general delay in client
product development programs resulting from recent financial pressures on
pharmaceutical and biotechnology companies.

         SG&A expenses increased to $3.6 million in 1994 from $1.1 million in
1993, an increase of $2.5 million. Of the increase, $1.8 million represented
SG&A expenses of TSI, including $242,000 of goodwill amortization. Exclusive of
TSI, SG&A expenses increased to $1.7 million in 1994 from $1.1 million in 1993,
an increase of 59%. The increase was due primarily to additions to the
management and sales organization in the latter part of 1993, the costs of which
existed for all of 1994 and only part of 1993. In addition to these direct
costs, the service fee covering Genzyme's administrative support totaled
$310,000 in 1994 and $144,000 in 1993. The increase was due to a full year of
charges in 1994.

         Interest income increased to $238,000 in 1994 from $156,000 in 1993, an
increase of 53%, primarily due to the investment of cash proceeds from the
Company's initial public offering for a full year in 1994. Interest expense was
$263,000 in 1994 compared with none in 1993. Of the total, $202,000 represented
interest expense incurred by TSI. Additionally, $61,000 of interest expense was
incurred in 1994 on financing provided by Genzyme for construction of the
transgenic production facility.

         The Company recognized $582,000 of Joint Venture losses in 1994
compared to none in 1993. The Company also reduced its investment by $58,000 in
1994 and $318,000 in 1993 due to impairment in the value of the Joint Venture.
The increase in the loss from the Joint Venture, as well as the decrease in the
reduction of the investment, was due to a combination of increased losses
incurred by the Joint Venture and a change in the accounting treatment related
to the investment.


LIQUIDITY AND CAPITAL RESOURCES

         The Company had cash, cash equivalents and short-term investments of
$2.0 million at March 31, 1996. During the first quarter of 1996, the Company
had a $2.4 million net decrease in cash: $4.6 million of cash was used in
operations (due primarily to the net loss of $2.0 million and an increase in
working capital of $3.3 million offset by $696,000 of non-cash charges),
$703,000 was invested in the transgenic production facility and other capital
equipment, $505,000 was used to pay down long-term debt and $300,000 was used to
pay down the Company's operating line of credit. Sources of funds during the
period included $2.8 million in advances under the Convertible Debt Agreement,
$475,000 of proceeds from the sale of GDRU which were released from escrow,
$352,000 in proceeds from long-term debt and $133,000 in proceeds from the
issuance of Common Stock.

         The Company had a working capital deficit of $9.5 million at March 31,
1996, compared to a deficit of $7.0 million at December 31, 1995. As of March
31, 1996, the Company had $300,000 available under its operating line of credit,
$7.2 million available under the Convertible Debt Agreement and $625,000
available under a capital lease line.

         Upon completion of this offering, Genzyme's commitment to advance funds
under the Convertible Debt Agreement will terminate and the Company will be
obligated to repay any outstanding amounts thereunder not previously converted
to Common Stock. The Company expects that, by June 30, 1996, an aggregate of
$3.1 million will have been advanced by Genzyme under the Convertible Debt
Agreement and that approximately $1.7 million of that amount will have been
converted into Common Stock. The remaining $1.4 million will be payable to
Genzyme upon completion of this offering.

         Management estimates that the proceeds from this offering, along with
existing cash balances and funds available from existing bank and lease lines,
will be sufficient to fund operations through the end of 1997. The foregoing is
a forward-looking statement. The Company's cash requirements may vary materially
from those now planned depending upon the results of the 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 other
factors. 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 when needed or on terms
acceptable to GTC, if at all. If additional financing cannot be obtained when
needed or on acceptable terms, to continue its operations GTC 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.

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


INTRODUCTION

         TSI was acquired by GTC on October 1, 1994. The audited financial
statements of TSI are included herein as a predecessor company of GTC within the
meaning of the applicable regulations of the Commission.

RESULTS OF OPERATIONS

Period from July 4, 1994 to September 30, 1994

         Total revenues were $8.5 million for the fiscal first quarter of which
80%, or $6.8 million, were from services and 20%, or $1.7 million, were from
products. TSI had no research and development revenues or expenses in the
quarter as its research and development agreement with Exemplar (the "Exemplar
Agreement") was terminated in November 1993.

         Cost of services was $6.8 million in the quarter. The break-even
performance in services was due primarily to a significant decrease in services
revenue reflecting reduced sales and marketing efforts due to financial
constraints, as well as customer concern regarding the financial condition of
TSI before its acquisition by GTC in October 1994.

         Cost of products was $1.5 million for the quarter, resulting in a
$239,000 gross profit, or a 14% gross margin. SG&A expenses were $3.5 million
for the quarter. Net loss for the quarter was $3.5 million.

Year Ended July 3, 1994 as Compared to Year Ended June 27, 1993

         For the fiscal year ended July 3, 1994, revenues decreased 15% to $49.6
million from fiscal 1993. The decrease in revenues was primarily the result of
the cessation of operations in the second quarter of fiscal 1994 at the
International BioResearch Group ("IBR") in Germany. Additionally, TSI's fiscal
1993 results included revenues from the Laboratory Animal Services ("LAS")
operation which was sold in June 1993 and from the Exemplar Agreement. In fiscal
1994, 81% of the revenues were derived from services, 18% from products and the
balance from the Exemplar Agreement. Excluding the results of IBR, LAS and the
Exemplar Agreement, revenues increased 9% in fiscal 1994 compared to fiscal
1993.

         Services revenues decreased 10% in fiscal 1994 to $40.2 million
primarily due to the cessation of operations of IBR. Excluding the results of
IBR, services revenues increased 17% reflecting strong demand in the preclinical
testing business. Product revenues declined 21% in fiscal 1994 to $8.7 million
from fiscal 1993 due primarily to diagnostic revenues below the unusually high
level in fiscal 1993, the elimination of LAS and the effects of the interruption
in business caused by the relocation of the TSI-Washington operation in the
second quarter of fiscal 1994. Research and development revenues decreased 74%
in fiscal 1994 to $682,000 from fiscal 1993 reflecting the termination of the
Exemplar Agreement.

         Cost of services for fiscal 1994 declined 12% to $32.8 million from
fiscal 1993. Excluding the results of IBR and $1.4 million of unusual charges
taken in the third quarter of fiscal 1993, cost of services increased 11% in
fiscal 1994 compared to fiscal 1993.

         Gross profit on services amounted to $7.5 million in fiscal 1994
compared to $7.3 million in fiscal 1993. The gross margin on services improved
to 19% in fiscal 1994 as compared to 16% in fiscal 1993, reflecting increased
cost control and revenue growth in the preclinical testing business. Excluding
the impact of IBR and the unusual charges, gross margin on services was 17% in
fiscal 1994 as compared to 13% in fiscal 1993.

         Cost of products decreased 14% in fiscal 1994 from fiscal 1993
reflecting the sale of LAS and a $451,000 charge to reserve for certain
slow-moving products incurred during fiscal 1993. Gross profit on products
decreased to $87,000 in fiscal 1994 from $741,000 in fiscal 1993. The gross
margin on products in fiscal 1994 decreased to 1% from 9% in fiscal 1993. The
decrease was primarily attributable to the relocation of TSI-Washington.

         SG&A expenses declined 31% in fiscal 1994 to $11.5 million compared to
fiscal 1993. Excluding the

                                     - 23 -

<PAGE>   24



impact of IBR, LAS and $1.6 million of unusual charges incurred in the third
quarter of fiscal 1993, SG&A expenses declined 4% reflecting the impact of TSI's
fiscal 1993 restructuring of operations.

         The net loss in fiscal 1994 was $3.9 million as compared to $32.0
million in fiscal 1993. The net loss in fiscal 1994 included a $1.0 million
one-time gain due to the settlement of an arbitration claim regarding the
purchase price paid by TSI for HSRI. The net loss in fiscal 1993 reflected
unusual charges relating to asset write-offs and expense accruals of $1.6
million, a restructuring charge of $15.6 million and a provision of $6.3 million
for the planned disposal of the LAS, IBR and CDP. Excluding the unusual charges,
restructuring charge and the provision from the disposal of operations, the net
loss was $8.3 million in fiscal 1993.

LIQUIDITY AND CAPITAL RESOURCES

         TSI had a zero cash position at September 30, 1994 compared to a
positive cash position of $787,000 at July 3, 1994. At September 30, 1994, TSI
had a working capital deficit of $8.5 million as compared to a deficit of $6.0
million at July 3, 1994. On October 1, 1994, TSI was acquired by GTC, which
subsequently funded its working capital deficit and future operations.

         TSI had a revolving line of credit with a commercial bank, which was
extended until August 1, 1994. Under the terms of the extension, TSI continued
to have a $1.0 million standby letter of credit and was able to borrow up to 70%
of the amount of eligible accounts receivable of its U.S. subsidiaries, subject
to a maximum borrowing of $2.0 million. In consideration for the extension, TSI
paid a fee of $100,000 and issued the bank 20,000 shares of TSI's common stock
and a warrant to purchase an additional 188,000 shares of TSI common stock which
became fully exercisable in July 1994.

         In connection with TSI's acquisition agreement with GTC, GTC agreed to
facilitate TSI's bank refinancing by providing certain credit enhancements and
interim financing. As part of the refinancing, GTC provided a guarantee of the
standby letter of credit facility and the equipment lease obligations
outstanding with the bank. In addition, GTC provided a secondary credit line of
up to $2.0 million subordinate to the amounts outstanding under the bank's
credit agreement through August 1, 1995.

         In June 1994, the bank modified and extended the credit agreement
through August 1, 1995. Under the terms of the extension, TSI was able to borrow
up to $3.0 million based upon 75% of eligible accounts receivable. In addition,
the bank agreed to increase the standby letter of credit from $1.0 million to
$1.5 million.

         In September 1994, TSI received a $2.0 million lease line with a
commercial leasing company. The leases required monthly payments over 36 months
at 10% with a fair market value buyout in the range of 5% to 10% of original
cost. A 25% cash deposit was payable at inception. As of September 30, 1994,
substantially all of the lease line was utilized.

                                    BUSINESS

GENERAL

         GTC 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 25 such proteins. For its
lead compound, AT-III, the Company has achieved clinical grade purity with high
recovery levels and has completed preclinical safety and efficacy studies. GTC
is also a leading 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 1995 were $26.4 million; revenues for the
quarter ended March 31, 1996 were $8.8 million, an increase of 76% above the
same period for 1995.

         GTC produces recombinant proteins transgenically by inserting into the
genetic material of an animal 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. 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
traditional 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. Current worldwide sales of plasma-derived AT-III exceed $200
million annually. 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 traditional methods. GTC has expressed
transgenic AT-III in goats, demonstrating stable expression across two
generations. Further, GTC has purified transgenic AT-III to clinical grade with
attractive yields. Preclinical safety and efficacy studies have been
successfully completed and GTC is preparing an IND for filing with the FDA to
initiate a Phase I clinical trial for this product.

         Other significant plasma proteins under development by GTC include API
and HSA. Additionally, GTC is working with corporate partners on a number of
monoclonal antibodies, including transgenic BR-96, which has potential
anti-cancer utility, under an agreement with Bristol-Myers. The Company is also
developing transgenic production processes for other proteins, including
prolactin, insulin and a protein for malaria vaccine.

         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 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 expects to produce vaccines for
approximately 20 patients in 1996.

TRANSGENIC PRODUCTION

    OVERVIEW AND STRATEGY

         A growing number of recombinant proteins are being developed for
therapeutic and diagnostic 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 cells. Moreover, bacteria or yeast
systems cannot produce many complex proteins. While mammalian cells can
reproduce 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. If successful, the resulting
animal, when mature, 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. For certain complex proteins, transgenic production may represent the
only technologically and economically feasible method of commercial production.

         Transgenic production may be achieved in any dairy species. To date,
the Company has worked principally with goats, which offer an attractive
combination of large milk volumes, relatively short generational time periods
and ease of handling and milking. Dairy goats mature six months after birth,
have a gestation period of five months and produce approximately 800 liters of
milk per year, which compares favorably with sheep, which have similar gestation
and maturation periods, but produce only one-half to three-quarters of the
volume of milk per year as goats. Although cows produce considerably more milk
per year than goats, the combined gestation and maturation period for cows is
approximately 24 months, compared to 11 months for goats. GTC's facility in
central Massachusetts currently houses more than 500 goats which were imported
from New Zealand for their scrapie-free certification.

         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. To
date, such contracts have generally consisted of feasibility studies aimed at
expressing a targeted protein in the milk of transgenic animals. GTC believes
that future collaborations will be of broader scope.

    ACHIEVEMENTS TO DATE

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

         o        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

                                     - 26 -

<PAGE>   27



                  times higher than those achievable in other production
                  systems. For example, proteins produced in mammalian cell
                  culture are typically expressed at levels considerably less
                  than 0.1 grams per liter.

         o        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, expressing five different
                  proteins.

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

         o        Together with 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.

         o        GTC recently completed the final preclinical safety and
                  efficacy studies required prior to filing an IND for AT-III.

         Although the Company plans to file an IND with the FDA to initiate a
Phase I clinical trial for AT-III later in 1996, to the Company's knowledge, no
protein produced in the milk of a transgenic animal has been submitted for
regulatory approval in the United States or elsewhere, nor has any entity
conducted human clinical trials of any such protein. There can be no assurance
that the Company's clinical trial will be allowed, and if allowed, will be
completed successfully. Likewise, there can be no assurance that regulatory
approval for AT-III will be received on a timely basis or at all. See "Risk
Factors-Government Regulation."

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 10,000, depending on geographic region.
Individuals with hereditary AT-III deficiency have an increased tendency
towards thromboses and are treated with AT-III protein replacement therapy
during periods when they are at high risk, 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 current worldwide market for plasma-derived AT-III is in
excess of $200 million annually.

         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 finalized 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 plans to file 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.

         GTC is developing recombinant human AT-III under a license from
Behringwerke AG, subject to a royalty

                                     - 27 -

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 long-term development and
supply agreement with GTC by March 1997. 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. The Joint Venture, which contributed development funding for AT-III
through December 1995, retains marketing rights to transgenic AT-III in Asia.
See "Business-Relationship with Genzyme" and "Business-Other Strategic
Collaborations."

         ALPHA1-PROTEASE INHIBITOR. 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 ("Prolastin") 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 is the protein principally responsible for
maintaining osmotic pressure and plasma volume. 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, gastric and intestinal malfunctions. HSA is currently
produced by human plasma fractionation, with worldwide sales for 1995 in excess
of $1.5 billion.

         GTC has expressed transgenic HSA in mice at levels equivalent to or
greater than 15 grams per liter. The Company believes that HSA is not the
subject of any composition of matter patent, and is in discussions with several
large multinational pharmaceutical companies with respect to further development
of 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 with many
more in development as therapeutics for cancer, cardiovascular disease, immune
system disorders 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, 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. Bristol-Myers' 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.
Bristol-Myers has tested BR-96 produced in the

                                     - 28 -

milk of mice, confirming its comparability to BR-96 made in cell culture and
initial product samples from founder female goats are expected in early 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 such companies as 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. More than a decade ago, recombinant DNA insulin was approved and 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.
GTC intends to seek a collaborator for the further development of transgenic
insulin. Insulin is not the subject of any composition of matter patents which
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 and
stimulation of lactation. Genzyme has a pending patent application 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.

         MALARIA VACCINE. Proteins used for human vaccines must be properly
processed by the cells that produce them in order to create the optimal
immunization levels and therefore protect against the infectious agent. Certain
mammalian cell cultures complete this task automatically. For systems which
cannot complete the necessary processing (microbial and yeast), the output must
be chemically modified to achieve the desired result. Public health approaches
and cost constraints require that the cost per vaccine dose be low, while
quantities of the protein required may be large. For some vaccines now in
development, the protein is not always expressed in the ideal form when it is
made in available systems, such as in yeast culture. GTC's transgenic expression
system has the potential to express the correct, most immunogenic, protein 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 in development and to examine the options for commercializing the
vaccine. GTC has begun discussions with potential collaborators on its vaccine
program.

         The Company believes that transgenic technology is also applicable to
the development of vaccines for other diseases.

         TRANSGENERICS. GTC has a program to identify and develop transgenic
production systems for generic products ("TransGenerics"). The first generation
of approved recombinant drugs will come off patent over the next several years.
As a result, brand name drugs, many of which have established significant
markets, may become vulnerable to competition from generic versions produced by
manufacturing methods which are more cost effective. GTC is developing
transgenically produced beta interferon and a long-acting form of tissue
plasminogen activator ("LA-tPA") and believes that Factor VIII and
erythropoietin may be candidates for transgenic production. These drugs
currently are approved products and have significant, established markets.

         LA-tPA has been expressed at gram per liter levels in two generations
of goats. Work has also begun on beta interferon. 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. According to recent estimates, the worldwide
revenues for non-clinical CRO services are in excess of $1 billion annually.

         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 acquisition of TSI in
October 1994 and 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 service to its clients. Fields in which GTC provides contract
services include:

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

       o 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.

      o  Photobiology Testing to measure 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.

      o  Developmental and Reproductive Toxicology Testing to measure 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.

      o  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

                                     - 30 -

<PAGE>   31



in related areas, its client base and its sales force enable the Company to
compete effectively in these fields. Clients have recently contracted with the
Company for GTC to provide 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 service 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 35% during 1995. 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 1995
were $26.4 million and revenues for the quarter ended March 31, 1996 were $8.8
million, representing a 76% increase above the same period for 1995.

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 an early clinical trial. The Company recently signed a
letter of intent to enter into a collaborative research and development
agreement with NCI to expand the clinical trials and 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. GTC believes that the
vaccine activates the patient's immune system to destroy the cancer cells which
often remain after traditional chemotherapy regimens.

         The principal clinical focus of the work today is on B-cell lymphoma,
with a secondary effort on multiple myeloma. There are approximately 43,000
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 three and a 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 is disease-free after three 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
expects to produce vaccines to treat approximately 20 patients in 1996. The
production cost for these vaccines will be borne by the NCI, and GTC will invest
in process development and scale-up.

RELATIONSHIP WITH GENZYME

         EQUITY POSITION. Genzyme is the largest single stockholder of the
Company, currently holding 6,335,044 shares of Common Stock. Genzyme also holds
a Common Stock Purchase Warrant exercisable for 145,000 shares of Common Stock
at a price of approximately $2.84 per share, the market price at the time of
issuance (the "Genzyme Warrant"). It is anticipated that $1.5 million of debt
will be converted, at GTC's option, to Common Stock at the then current market
price on June 30, 1996 under the Convertible Debt Agreement discussed below.
Assuming the market price is $9.00 per share, 166,667 shares would be issued
upon such conversion. Assuming exercise of the Genzyme Warrant and issuance of
166,667 shares on conversion of debt on June 30, 1996, after giving effect to
this offering, Genzyme will own approximately 40% of the outstanding Common
Stock. In addition to the amounts expected to be converted at GTC's option, all
remaining indebtedness may be converted, prior to repayment, into Common Stock
at Genzyme's option. The Company expects that the outstanding balance will be
repaid to Genzyme in cash upon the closing of this offering.

         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 26,244 shares in 1996 in exchange for conversion of debt at the then
current market prices. The remaining 475,467 shares were issued to Genzyme in
July 1995 in exchange for shares of Genzyme common stock issued as a portion of
the consideration for the acquisition of BDL. 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

                                     - 31 -

below. All of the shares held by Genzyme are entitled to certain registration
rights. See "Description of Capital Stock."

         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
         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 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.

                  Genzyme R&D Agreement. Pursuant to the Genzyme R&D Agreement,
         Genzyme and GTC agreed, until May 1, 1998, to provide research and
         development services for 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 is no less than 80% of the annual budgets
         established by the parties under the Genzyme R&D Agreement, plus, in
         most cases, a fee equal to 10% of such costs.

                  AT-III Development Funding.  Under the Convertible Debt 
         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 development and supply agreement is not executed
         by the parties prior to March 31, 1997. See "Business-Transgenic
         Production."

         OTHER ARRANGEMENTS.  GTC and Genzyme have also entered into a number of
         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 $169,000
         under the Lease in 1995. See "Facilities."

                  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 secured by Genzyme's guaranty of the Company's
         obligations thereunder (currently up to $9.8 million). 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. The line of credit will terminate upon the closing of this
         offering and all outstanding amounts will become due and payable. GTC
         anticipates that on June 30, 1996, a portion of the outstanding balance
         may be converted to GTC Common Stock at an average market price over
         the 20 trading days ending June 28, 1996. The Company currently
         estimates that $1.5 million of debt will be converted at June 30, 1996,
         at the then current market price. As of May 31, 1996, approximately
         $2.4 million was outstanding under the revolving line of credit and
         $150,000 of debt had been converted into 26,244 shares of Common Stock
         in 1996. See "Use of Proceeds."

                  Insurance.  The Company currently participates together with 
         other Genzyme affiliates as a co-

                                     - 32 -

<PAGE>   33



         insured under an insurance policy maintained by Genzyme, which includes
         product and professional liability coverage. Claims made by either
         Genzyme or any Genzyme affiliate under such insurance policy with
         respect to a particular form of liability automatically reduce the
         scope of the related liability coverage available for other co-insured
         parties thereunder. See "Risk Factors-Risk of Service or Product
         Liability."

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 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 and
other proteins (the "Funded Proteins") through October 1996. From its inception
until the acquisition of TSI, the Joint Venture provided the majority of GTC's
revenues. 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. See
"Business-Transgenic Production."

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 been notified by the European Patent Office of the Office's
intention to grant 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 "Business-Legal Proceedings."

         There can be no assurance that patent applications filed by GTC will
result in patents being issued or that any patents issued to or licensed by GTC
will be held valid. The Company may also be subject to claims that result in the
revocation of patent rights previously licensed to GTC as a result of which the
Company may be required to obtain licenses from others to continue to develop,
test or commercialize its products. There can be no assurance that GTC will be
able to obtain such licenses on acceptable terms, if at all. In addition, there
may be pending or issued patents held by parties not affiliated with GTC that
relate to the technology utilized by GTC. As a result, GTC may need to acquire
licenses to, or contest the validity of, such patents or any other similar
patents which may be issued. GTC could incur substantial costs in defending
itself against challenges to patent or infringement claims made by third parties
or in enforcing any patent rights of its own.

         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. These agreements are
intended to enable the Company to protect its proprietary information by
controlling the disclosure and use of technology to which it has rights and
provide for ownership by the Company of proprietary technology developed at the
Company or with the Company's resources. There can be no assurance, however,
that

                                     - 33 -

<PAGE>   34



these agreements will provide meaningful protection for the Company's trade
secrets or other confidential information in the event of unauthorized use or
disclosure of such information. The loss or exposure of trade secrets possessed
by GTC could adversely affect its business. See "Risk Factors-Uncertainty
Regarding Patents and Proprietary Technology."

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 engaged in the development of recombinant proteins
in the milk of transgenic cows, which are most suitable for extremely high
volume protein production. PPL Therapeutics PLC, which is based in Scotland,
utilizes sheep for their protein production. See "Business-Legal Proceedings."

         GTC's success will depend on its continued ability to attract and
retain qualified personnel, to develop and secure the rights to advanced
proprietary technology and to exploit commercially its technology in a timely
and cost effective manner so that transgenic production systems are competitive
with existing and future therapeutics production systems.

  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 government 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 a significant
competitive factor. See "Risk Factors-Competition."

GOVERNMENT REGULATION

  TRANSGENICS

         The manufacturing and marketing of GTC's potential products, and
certain areas of research related to them, are subject to regulations by
governmental authorities in the United States, including the FDA, the USDA and
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 regulatory approval. However, the FDA issued the
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 the basic
U.S. regulatory framework for the transgenic production of recombinant proteins
in animals to 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 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, the standard FDA approval process
includes preclinical laboratory and animal testing, submission of an IND
application to the FDA, appropriate human clinical trials to establish safety
and effectiveness and submission of an NDA prior to market introduction. Based
on the information available to it, the Company expects the same process to
apply to transgenically produced products, with the approval process 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.


                                     - 34 -

<PAGE>   35



         With respect to obtaining approval for the production facilities to be
used in producing a therapeutic product, the Company expects to be subject to
both the requirements for Establishment License Applications and the Points to
Consider. See "Risk Factors-Government Regulation."

  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 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 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 is
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 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. See "Risk Factors-Dependence of Testing Services on Current Government
Regulatory Requirements."

         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.

EMPLOYEES

         As of March 31, 1996, GTC employed 433 people. Of these, 274 were
engaged in operations, 37 were engaged in research and development and 122 were
engaged in marketing and general administration. None of GTC's employees are
covered by collective bargaining agreements. GTC believes its employee relations
are positive.

FACILITIES

         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 "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

                                     - 35 -

<PAGE>   36



occupies 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 for
preclinical testing. The remaining 37,400 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, 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.

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 a declaratory judgment which would effectively rescind the Company's
intellectual property rights under the License Agreement, injunctive relief and
unspecified damages. GTC has denied Pharming B.V.'s allegations 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 no 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 Company, including potential delays in the
commercialization of the Company's transgenic proteins and increased costs.

         On June 17, 1994, a law suit 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 deny 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.

           Pursuant to the Company's Restated Articles of Organization, the
Board of Directors of the Company is divided into three classes, with each class
being as nearly equal in number of directors as possible. The term of one class
expires, and their successors are elected for a term of three years, at each
annual meeting of the Company's stockholders.

           The Company has standing Audit and Compensation Committees of the
Board of Directors, but does not have a Nominating Committee. The Audit
Committee, consisting of Messrs. Baldridge, Blair and Tuck, held three meetings
in 1995. The primary function of the Audit Committee is to assist the Board of
Directors in the discharge of its duties and responsibilities by providing the
Board with an independent review of the financial health of the Company and of
the reliability of the Company's financial controls and financial reporting
systems. The committee reviews the general scope of the Company's annual audit,
the fee charged by the Company's independent accountants and other matters
relating to internal control systems.

           The Compensation Committee of the Board of Directors determines the
compensation to be paid to all executive officers of the Company (except Messrs.
Termeer and Lebson, who are compensated by Genzyme), including the Chief
Executive Officer. The Compensation Committee also administers the Company's
1993 Equity Incentive Plan (the "Equity Plan"), including the grant of stock
options and other awards under the Equity Plan. The Compensation Committee held
five meetings during 1995. The Compensation Committee is currently composed of
Messrs. Bullock (Chairman), Blair and Tuck.

(1)  The dollar amounts under these columns are the result of calculations at
     the 5% and 10% rates set by the Commission and, therefore, are not intended
     to forecast possible future appreciation, if any, in the price of the
     underlying Common Stock. No gain to the optionees is possible without an
     increase in price of the Common Stock, which will benefit all shareholders
     proportionately. In order to realize the potential values set forth in the
     5% and 10% columns of this table, the per share price of the Common Stock
     would have to be $4.89 and $7.78, or approximately 63% and 159% above the
     respective exercise or base price shown. The amount shown for all
     stockholders reflects the potential value to all stockholders if the price
     of the Common Stock appreciates at such rates over the term of the options,
     assuming a purchase in 1995 at the option exercise price shown.

EXECUTIVE EMPLOYMENT AGREEMENTS

         James A. Geraghty. Under the terms of an Employment Agreement between
Mr. Geraghty and the Company, Mr. Geraghty's base salary will be no less than
$190,000 per annum. He is also eligible to receive performance and incentive
bonuses as determined by the Company's Compensation Committee, which has set his
maximum cash bonus for 1996 at 40% of such base salary.

         John B. Green. Under the terms of an Employment Agreement between Mr.
Green and the Company, Mr. Green's base salary will be no less than $135,000 per
annum and the maximum amount of his annual bonus will be 25% of his base salary,
with such bonus payable on each December 31, subject to satisfaction of certain
established performance goals relating to individual and Company performance.

         Harry M. Meade. Under the terms of an Employment Agreement between Dr.
Meade and the Company, Dr. Meade's base salary will be no less than $126,000 per
annum. Under the agreement, he is also eligible to receive bonuses based on
individual and Company performance, and the Company's Compensation Committee has
established a maximum bonus for 1996 equal to 25% of such base salary.

         Each of the foregoing agreements will remain in effect until terminated
in accordance with its terms. In the event that the Company terminates any of
the foregoing employees without cause or if any of such employees terminates his
agreement upon a "change of control" of the Company, as such term is defined in
each of the employment agreements, such employee will immediately be paid the
maximum bonus for the year of termination, prorated on the basis of the portion
of the year completed, and will continue to receive his then current base salary
for a severance period. In the case of Mr. Geraghty, the severance period is two
years. In the case of Mr. Green, the severance period in the event of a "change
in control" is two years and otherwise is one year. In the case of Dr. Meade,
the severance period is one year. If any of the foregoing employees terminates
his agreement upon a change of control, such severance payments will be reduced
by income which such employee derives during the relevant severance period from
a subsequent employer. In any case in which the Company must pay severance upon
a change in control, outstanding stock options held by the affected employee
which are not then exercisable shall immediately become exercisable.

                          DESCRIPTION OF CAPITAL STOCK

         The authorized capital stock of the Company consists of 24,000,000
shares of Common Stock, $0.01 par value per share, and 5,000,000 shares of
preferred stock, $0.01 par value per share (the "Preferred Stock").

         The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Restated Articles of
Organization (the "Articles"), which are included as an exhibit to the
Registration Statement, and by the provisions of applicable law.

COMMON STOCK

         Holders of Common Stock are entitled to one vote per share on matters
to be voted upon by the stockholders. There are no cumulative voting rights.
Holders of Common Stock are entitled to receive ratable dividends when, as and
if declared by the Board of Directors out of funds legally available therefor.
Upon the liquidation, dissolution or winding up of the Company, holders of
Common Stock share ratably in the assets of the Company available for
distribution to its stockholders, subject to the preferential rights of any then
outstanding shares of Preferred Stock. No shares of Preferred Stock will be
outstanding immediately following the effective date of the Registration
Statement. The Common Stock outstanding upon the effective date of the
Registration Statement, and the shares offered by the Company hereby upon
issuance and sale, will be fully paid and nonassessable.

PREFERRED STOCK

         The Company's Board of Directors has the authority to issue up to
5,000,000 shares of Preferred Stock in one or more series and to fix the
relative rights, preferences, privileges, qualifications, limitations and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the designation
of such series, without further vote or action by the stockholders. The Board of
Directors could, without the approval of the stockholders, issue Preferred Stock
having voting or conversion rights that could adversely affect the voting power
of the holders of Common Stock and the issuance of Preferred Stock could be
used, under certain circumstances, to render more difficult or discourage a
hostile takeover of the Company. The Company has no present plans to issue any
shares of Preferred Stock.

STOCK PURCHASE RIGHTS

         Upon its acquisition of TSI, GTC assumed an outstanding warrant that
TSI had issued to a commercial bank, currently exercisable for 37,600 shares of
Common Stock at exercise price of $0.05 per share. This warrant terminates on
October 28, 1998.

         In consideration for Genzyme's guaranty of a line of credit with a
commercial bank, GTC issued a Common Stock Purchase Warrant to Genzyme covering
145,000 shares at a price of approximately $2.84 per share. This warrant
terminates on July 3, 2005.

         In partial consideration for an equipment leasing facility with
Financing For Science International, Inc. ("FSI"), GTC has issued three Common
Stock Purchase Warrants to FSI covering an aggregate of 8,000 shares of Common
Stock (the "FSI Warrants"). The purchase rights represented by these warrants
are currently exercisable at prices ranging from $0.10 per share to $6.50 per
share. The FSI Warrants terminate on January 1, 2000 with respect to 4,000
shares and on December 31, 2001 with respect to 4,000 shares.

         Under the Convertible Debt Agreement, all outstanding amounts will
become due on the closing of this offering. GTC has the option to convert a
portion of the outstanding balance on June 30, 1996 to Common Stock. GTC
anticipates that 166,667 shares will be issued to Genzyme on June 30, 1996,
representing the conversion of $1,500,000 of indebtedness at an assumed price of
$9.00. It is anticipated that approximately $1.4 million will be outstanding
under such agreement at the closing of this offering. Prior to repayment the
entire balance may be converted at Genzyme's option, to Common Stock at the then
current market price. It is not anticipated that Genzyme will exercise such
conversion option.


                                     - 47 -

<PAGE>   48



STOCK OPTIONS

         GTC maintains the Equity Plan and the Director Plan. Options for all of
the authorized shares for the Director Plan have been issued and are unexercised
while options for 1,532,896 shares have been issued and are outstanding under
the Equity Plan, of which 1,461,310 are unexercised.

REGISTRATION RIGHTS

         FSI is entitled to certain rights with respect to registration under
the Securities Act of an aggregate of 8,000 shares of Common Stock issuable upon
exercise of the FSI Warrants. If the Company proposes to register any of its
securities under the Securities Act, either for its own account or for the
account of other security holders, the Company is required under the FSI
Warrants to use its best efforts to include the shares of Common Stock issuable
to FSI in such registration. These shares will not form a part of the shares of
Common Stock registered in this offering. In addition, under the Series A
Convertible Preferred Stock Purchase Agreement dated May 1, 1993, Genzyme has
certain demand and piggyback registration rights with respect to its shares of
Common Stock but is not expected to exercise these rights in conjunction with
this offering.

ANTI-TAKEOVER MEASURES

         In addition to the Board of Directors' ability to issue shares of
Preferred Stock in series, the Articles and the Bylaws of the Company (the
"Bylaws") contain several other provisions that are commonly considered to have
an anti-takeover effect. The Articles include a provision classifying the Board
of Directors into three classes with staggered three-year terms, and the Bylaws
include a provision prohibiting stockholder action by written consent except as
otherwise provided by law. Under Massachusetts law, action taken by stockholders
without a meeting requires their unanimous written consent. Under the Articles
and Bylaws, the Board of Directors may enlarge the size of the Board and fill
any vacancies on the Board. The Bylaws provide that nominations for directors
may not be made by stockholders at any annual or special meeting unless the
stockholder intending to make a nomination notifies the Company of its intention
a specified period in advance and furnishes certain information. The Bylaws also
provide that special meetings of the Company's stockholders may be called only
by the President or the Board of Directors or upon written application of
holders of not less than 90% (or such lesser percentage as may be required by
law) of the stock entitled to vote at the meeting and require advance notice of
business to be brought by a stockholder before the annual meeting.

         The Company, as a Massachusetts corporation, is subject to the
Massachusetts Business Combination statute and may, in the future, be subject to
the Massachusetts Control Share Acquisition statute. Under the Massachusetts
Business Combination statute, a person (other than certain excluded persons) who
acquires 5% or more of the stock of a Massachusetts corporation without the
approval of the Board of Directors (an "interested stockholder") may not engage
in certain transactions with the corporation for a period of three years
following such acquisition. There are certain exceptions to this prohibition,
including, if the Board of Directors approves the acquisition of stock or the
transaction prior to the time that the person became an interested stockholder,
or if the interested stockholder acquires 90% of the voting stock of the
corporation (excluding voting stock owned by directors who are also officers and
certain employee stock plans) in one transaction, or if the transaction is
approved by the Board of Directors and by the affirmative vote of two-thirds of
the outstanding voting stock which is not owned by the interested stockholder.

         Under the Massachusetts Control Share Acquisition statute, a person
(the "Acquiror") who makes a bona fide offer to acquire, or acquires, shares of
the Common Stock that when combined with shares already owned, would increase
the Acquiror's ownership to at least 20%, 33% or a majority of the voting stock
of the Company must obtain the approval of a majority of shares held by all
stockholders exclusive of those shares held by the Acquiror and the officers and
inside directors of the Company in order to vote the shares acquired. The
statute does not require the Acquiror to consummate the purchase before the
stockholder vote is taken. The Bylaws contain an election by the Company not to
be governed by the Massachusetts Control Share Acquisition statute. However, if
at a future date the Board of Directors determines that it is in the best
interests of the corporation and its stockholders to be governed by the statute,
the Board of Directors may amend the Bylaws to permit the Company to be governed
by the statute. Any such amendment, however, would apply only to acquisitions
crossing the thresholds which occur after the effective date of such amendment.

         The foregoing provisions of Massachusetts law and the Articles and
Bylaws could have the effect of discouraging others from attempting hostile
takeovers of the Company and, as a consequence, they may also inhibit

                                     - 48 -

<PAGE>   49



temporary fluctuations in the market price of the Common Stock that might result
from actual or rumored hostile takeover attempts. Such provisions may also have
the effect of preventing changes in the management of the Company. It is
possible that such provisions could make it more difficult to accomplish
transactions which stockholders may otherwise deem to be in their best
interests.

TRANSFER AGENT

         The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.


                         SHARES ELIGIBLE FOR FUTURE SALE

         Upon completion of this offering, the Company will have 16,338,046
shares of Common Stock outstanding, assuming no exercise of the Underwriters'
over-allotment option or of any other outstanding options, warrants or other
rights to purchase Common Stock. Of these shares, 7,003,002 shares and the
3,000,000 shares sold in this offering will be freely tradable, without
restriction or further registration under the Securities Act, except for shares
purchased by "affiliates" of the Company as that term is defined in Rule 144
under the Securities Act.

         The remaining 6,335,044 outstanding shares of Common Stock are owned by
Genzyme and are deemed "Restricted Shares" under Rule 144. These may not be
resold, except pursuant to an effective registration statement or an applicable
exemption from registration, including Rule 144. Immediately after this
offering, approximately 4,000,000 of these Restricted Shares will be eligible
for sale in the public market pursuant to Rule 144. The remaining Restricted
Shares will become eligible from time to time thereafter upon the expiration of
the minimum two-year holding period prescribed by Rule 144.

         In general, under Rule 144, as currently in effect, a person (or
persons whose shares are aggregated), including an affiliate, who has
beneficially owned Restricted Shares for at least two years from the later of
the date such Restricted Shares were acquired from the Company and (if
applicable) the date they were acquired from an affiliate, is entitled to sell,
within any three-month period, a number of shares that does not exceed the
greater of 1% of the then outstanding shares of Common Stock or the average
weekly trading volume in the public market during the four calendar weeks
preceding such sale. Sales under Rule 144 are also subject to certain
requirements as to the manner and notice of sale and the availability of public
information concerning the Company. Affiliates may sell shares not constituting
Restricted Shares in accordance with the foregoing volume limitations and other
restrictions, but without regard to the two-year holding period. All shares,
including Restricted Shares, held by affiliates of the Company eligible for sale
in the public market under Rule 144 are subject to the foregoing volume
limitations and other restrictions.

         The Commission has proposed an amendment to Rule 144 which would reduce
the holding period required for shares subject to Rule 144 from two years to one
year. If this proposal is adopted, as of the expected closing of this offering
an additional 2,308,800 shares of Common Stock will become eligible for sale by
Genzyme to the public.

         The Company has filed registration statements under the Securities Act
to register 2,015,000, 50,000 and 300,000 shares of Common Stock issuable under
the Equity Plan, the Director Plan and the Stock Purchase Plan, respectively, of
which 71,586, 0 and 142,735 shares, respectively, had been issued as of May 31,
1996. In addition 1,705,991 and 50,000 shares were subject to outstanding option
grants under the Equity Plan and the Director Plan, respectively. Such shares
are eligible for immediate resale upon exercise, subject, in the case of
affiliates, to the volume and notice requirements of Rule 144.

         The Company, its directors, executive officers and certain employees
have agreed that they will not, without the prior consent of the representatives
of the Underwriters, offer to sell, sell, contract to sell, grant any option to
sell or otherwise dispose of or require the Company to file with the Commission
a registration statement under the Act to register any shares of Common Stock,
or securities convertible or exchangeable for shares of Common Stock, or
warrants or other rights to acquire shares of Common Stock (other than shares
acquired through the Company's Employee Stock Purchase Plan) during the 90-day
period following the effective date of the Registration Statement.

         Genzyme is, and future transferees of shares owned by Genzyme will be,
entitled to both demand and piggyback registration rights with respect to all
6,335,044 shares of Common Stock owned by Genzyme as well as

                                     - 49 -

<PAGE>   50



shares issuable on exercise of the Genzyme Warrant and under the Convertible
Debt Agreement.

         Genzyme has agreed that it will not, without the prior consent of the
representatives of the Underwriters, offer to sell, sell, contract to sell,
grant any option to sell or otherwise dispose of or require the Company to file
with the Commission a registration statement under the Act to register any
shares of Common Stock, or securities convertible or exchangeable for shares of
Common Stock, or warrants or other rights to acquire shares of Common Stock
during the 180-day period following the effective date of the Registration
Statement.

         No prediction can be made as to the effect, if any, that market sales
of the Restricted Shares or the availability of such Restricted Shares for sale
will have on the market price of the Common Stock. Nevertheless, sales of
substantial amounts of Common Stock in the public market may have an adverse
impact on the market price for the Common Stock. See "Risk Factors-Dilution."

</TABLE>


         The Company has been advised by the Representatives that the
Underwriters propose to offer the shares of Common Stock to the public at the
public offering price set forth on the cover page of this Prospectus and to
certain securities dealers at such price, less a concession not in excess of
$_____ per share, and that the Underwriters and such dealers may reallow to
other dealers, including the Underwriters, a discount not in excess of
$_________ per share. After the commencement of the public offering, the
concessions to selected dealers and the discounts to other dealers may be
changed by the Representatives.

         The Company has granted to the Underwriters an option, exercisable
during the 30-day period after the date of this Prospectus, under which the
Underwriters may purchase up to an additional 450,000 shares of Common Stock
from the Company at the public offering price set forth on the cover page of
this Prospectus, less underwriting discounts and commissions. The Underwriters
may exercise the option only to cover over-allotments, if any. To the extent
such option is exercised, each Underwriter will become obligated, subject to
certain conditions, to purchase approximately the same percentage of such
additional shares as it was obligated to purchase pursuant to the Underwriting
Agreement.

         Each of the Company, its directors, executive officers and certain
employees and Genzyme have agreed that they will not, during the 90-day period
(with respect to the Company, its directors, executive officers and certain
employees) or the 180-day period (with respect to Genzyme) following the
effective date of the Registration Statement, without the prior written consent
of the Representatives, offer to sell, sell, contract to sell, grant any option
to sell or otherwise dispose of or require the Company to file with the
Commission a registration statement under the Act to register any shares of
Common Stock, or securities convertible or exchangeable for shares of Common
Stock, or warrants or other rights to acquire such shares of Common Stock
(other than through the Company's Employee Stock Purchase Plan).

         In connection with this offering, certain Underwriters may engage in
passive market making transactions in the Common Stock on Nasdaq immediately
prior to the commencement of sales in this offering in accordance with Rule
10b-6A under the Exchange Act. Passive market making consists of displaying bids
on Nasdaq limited by the bid prices of independent market makers for a security
and making purchases of a security which are limited by such prices and effected
in response to order flow. Net purchases by a passive market maker on each day
are limited to a specified percentage of the passive market maker's average
daily trading volume in the Common Stock during a specified prior period and
must be discontinued when such limit is reached. Passive market making may
stabilize the market price of the Common Stock at a level above that which might
otherwise prevail and, if commenced, may be discontinued at any time.

                       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 31, 1994 and 1995 and the related consolidated
statements of operations, cash flows and stockholders' equity for each of the
three years in the period ended December 31, 1995. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Genzyme Transgenics Corporation as of December 31, 1994 and 1995 and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1995 in conformity with generally
accepted accounting principles.

                        GENZYME TRANSGENICS CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 (INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED MARCH 31, 1995 AND 1996 IS
                                   UNAUDITED;
               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 years ended December 31, 1993, 1994
and 1995. The Company had a working capital deficit of $7.0 million and $9.5
million at December 31, 1995 and March 31, 1996, respectively. The Company
expects to continue to operate with negative working capital for the foreseeable
future.
 
     In March 1996, the Company entered into a Convertible Debt and Development
Funding Agreement with Genzyme Corporation ("Genzyme") under which Genzyme
agreed to provide a revolving line of credit in the amount of $10 million and
has agreed to fund development costs of the AT-III program. Upon completion of
an offering of Common Stock which generates net proceeds to the Company of at
least $10 million, Genzyme's commitment to advance funds under the Convertible
Debt and Development Funding Agreement will terminate and the Company will be
obligated to repay any amounts outstanding not previously converted to Common
Stock. Under the Company's 1996 operating plan, existing cash balances along
with funds available under the bank line and the Convertible Debt and
Development Funding Agreement are expected to be sufficient to fund the Company
through March 31, 1997.
 
     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. In May 1993, Genzyme entered
into a stock purchase agreement under which Genzyme purchased 4 million shares
of the Company's Series A Convertible Preferred Stock in exchange for entering
into the Technology Transfer Agreement, the Research and Development Agreement,
the Sublease Agreement and the Services Agreement, as described in Note 10. This
transaction involved Genzyme transferring substantially all of the assets and
liabilities of its transgenic business unit (the "Division"), which was
established in 1986, to the Company in exchange for all of the outstanding
shares of the Company's Series A Convertible Preferred Stock.
 
     The accompanying financial statements reflect the May 1993 equity
transaction and include assets, liabilities, revenue and expenses of the
Division at Genzyme's historical cost. Genzyme funded the Division's operations
through July 16, 1993. Operating losses from inception through the effective
date of Genzyme's transfer of assets and technology have been recorded as a
reduction of the net balance advanced to the Company by Genzyme.
 
     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").

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
In July 1995, the Company acquired BDL. The Company has accounted for both of
these acquisitions using the purchase method as fully described in Note 3.
 
     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.
 
     Subsequent to the Company's initial public offering ("IPO") in July 1993,
as described in Note 6, Genzyme owned approximately 73% of the Company's
outstanding stock. Subsequent to the Company's acquisition of TSI in October
1994, Genzyme owned approximately 40% of the Company. In February 1995, Genzyme
purchased 500,000 additional shares of the Company's common stock pursuant to a
Common Stock Put Agreement (see Note 6), resulting in approximately a 43%
interest in the Company. In June 1995, Genzyme exchanged $4 million in
outstanding indebtedness of the Company for 1,333,333 shares of the Company's
Common Stock (see Note 5) after which it owned approximately 49% of the Company.
In July 1995, the Company purchased BDL for stock after which Genzyme owned
approximately 48% of the Company (see Note 3).
 
UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
 
     The unaudited consolidated financial statements as of March 31, 1996 and
for the three month periods ended March 31, 1994 and 1995 have been prepared by
management in accordance with generally accepted accounting principles. In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included. Operating
results of interim periods are not necessarily indicative of the results that
may be expected for a full year.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. 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 affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. 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 cost plus accrued interest, which approximates market.
 
RESTRICTED CASH
 
     Restricted cash represents cash from the sale of GDRU that is held in
escrow and could become unrestricted during 1996, subject to the terms of the
escrow agreement and related share purchase agreement.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
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 31, 1995, there were
no short-term investments.
 
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 over a twenty-year period. Accumulated amortization at December 31,
1995 was $1,150,000. The carrying value of goodwill is periodically reviewed by
management. When material adverse changes in operations are noted, management
will determine the amount by which the related goodwill has been impaired, if
any. In connection with the sale of GDRU and in accordance with the principles
outlined in FAS 121, 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 for 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. At December 31, 1995 goodwill in connection with the purchase of
TSI was $15,860,000.
 
     There was $7,329,000 of excess consideration paid and costs incurred over
the net fair value of assets acquired by GTC of BDL (Note 3). This amount is
being amortized using the straight-line method over twenty years. Accumulated
amortization at December 31, 1995, was $183,000.
 
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.

respectively. Accumulated amortization for equipment under capital lease was
$375,000 and $741,000 at December 31, 1994 and 1995, respectively.
 
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 fair value of the assets with their
carrying amount. Any write-downs are to be treated as permanent reductions in
the carrying amount of the assets.
 
ACCRUED EXPENSES

     As a result of the acquisition of BDL, the Company established severance
reserves of $542,000 for the elimination of 19 positions of which 9 were
laboratory positions, 3 were accounting/finance positions and 7 were general and
administrative positions. As of December 31, 1995, $224,000 has been paid,
leaving a balance of $318,000, which is expected to be paid in 1996. During the
three months ended March 31, 1996, additional payments of $100,000 were made
leaving a balance at March 31, 1996 of $218,000.
 
     As a result of the merger with TSI, the Company established severance
reserves for the elimination of 35 positions of which 20 were laboratory

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. Of the $839,000 short-term accrued severance reserves, $105,000 had been
paid out through December 31, 1994. As of December 31, 1995, $650,000 has been
paid out leaving a balance of $662,000 of which $419,000 is classified as
long-term.
 
INVESTMENT IN JOINT VENTURE
 
     In 1990, the Company entered into a Joint Venture as a 25% owner (see Note
12). In 1992, the Company's ownership percentage declined to 20% based on
additional investments by the partners. Through August 1992, the date of that
change, the Company's investment in the Joint Venture was accounted for under
the equity method and, accordingly, the Company recorded its share of the Joint
Venture's losses in its statements of operations. Beginning August 1992, the
investment in the Joint Venture was accounted for using the cost method.
However, because the Joint Venture R&D program was being funded in part by the
Company and the Joint Venture had a series of operating losses, the Company
reduced its investment in the Joint Venture to reflect the impairment in value
of the investment. Additionally, the Company recognized revenue for amounts
received from the Joint Venture pursuant to the Joint Venture R&D Agreement. 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 recognized 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
 
<TABLE>
     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 revenues are generally recognized upon
shipment. R&D revenues from the Joint Venture (see Note 12), related parties
(see Note 10) and commercial clients were as follows:

</TABLE>
 
     Profits expected to be realized on contracts are based on the Company's
estimates of total contract sales value and 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 contract-related
revenues, the full amount of the anticipated contract loss is immediately
recognized.
 
TRANSLATION OF FOREIGN CURRENCIES
 
     Assets and liabilities of foreign subsidiaries are translated at year-end
exchange rates, and statement of operations accounts are translated at average
exchange rates. Resulting translation adjustments are recorded in a separate
component of stockholders' equity, "Accumulated translation adjustment."

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.
 
INCOME TAXES
 
     The Company follows the asset and liability method of 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.
 
RECLASSIFICATION
 
     Current amounts in the prior years' financial statements have been
reclassified to conform to the 1995 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 resulting
goodwill of $19,397,000. The Company has accounted for the acquisition using the
purchase method, therefore only 3 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 1993. 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 or which may occur in the future.

     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. 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 is being accounted for under the purchase method
and the resulting goodwill of $7,329,000 will be 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 was assigned to the non-competition provision. The
consulting period runs for three years and the non-competition period runs for
ten years from the date of the Agreement. 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 at the
transaction.

     In August 1995, the Company completed the closure of HSRI, a small clinical
trials monitoring unit in San Diego, California. The related closure expenses of
approximately $166,000 were recorded in the third quarter of 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 included a tax charge of $3,401,000 and a $2 million
writedown of goodwill identifiable with GDRU. In conjunction with this
transaction, the Company received $1,425,000 of restricted cash which becomes
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

     The Company leases equipment and facilities under various operating and
capital leases (see also Note 5). 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 years ended
December 31, 1993, 1994 and 1995 was approximately $29,000, $528,000 and
$2,553,000, respectively, and for the three months ended March 31, 1995 and 1996
was approximately $416,000 and $641,000, respectively.
 
     At December 31, 1995, 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

Plan of Merger dated June 14, 1994 among TSI, GTC and such subsidiary of GTC

"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 deny 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.
 
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 of credit was replaced by a term loan with a
commercial bank (described below). Interest expense of $56,000 and $180,000 for
the years ended December 31, 1994 and 1995, respectively, and $64,000 for the
three months ended March 31, 1995 was incurred in connection with this line of
credit.
 
     At the date of the TSI acquisition, TSI had certain arrangements with a
commercial bank (the "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
$4 million based on 85% of eligible accounts receivable, $2 million to pay down
term debt of BDL, and $1.5 million for an existing standby letter of credit in
support of a major facility lease. The $2 million facility was repaid from the
proceeds from the sale of GDRU. 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 9.52%.
 
     The Credit Agreement was amended effective December 1995 to provide an
additional $2 million in credit based on the Company's eligible accounts
receivable. As of December 31, 1995, $6 million 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 at December
31, 1995.
 
     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 bank line of credit, the Company has agreed not to pay any
dividends until the loans have been repaid. Subsequent to December 31, 1995, the
Company obtained an extension of the revolving line of credit to March 31, 1997
(see also Note 13).
 
     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.
 
     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 (in the range of 5%
to 10% of original cost) at the end of the lease term. The Lease Agreement
required a 25% cash deposit at inception which may be reduced to 10% or fully
refunded under certain conditions.
 
     In December 1995, an additional $1 million was made available under the
lease line (the "new line"). Leases under the new line require monthly payments
over 48 months with a fair market value buyout. No cash deposit is required
under the new line. At December 31, 1995, $1 million was available under the
lease lines.

COMMON STOCK AND WARRANTS
 
     The Company's authorized capital stock consists of 24 million shares of
Common Stock, par value $0.01 per share, and 5 million shares of Preferred
Stock, par value $0.01 per share. Prior to the Company's IPO, the Board of
Directors designated 4 million shares of Preferred Stock as Series A Convertible
Preferred Stock ("Series A Stock") which were issued to Genzyme in connection
with the transfer of assets and liabilities described in Note 2, and reserved 4
million shares of the Company's Common Stock for issuance upon conversion of the
Series A Stock.
 
     On July 16, 1993, the Company completed the IPO of 1.5 million shares of
its Common Stock priced at $8.00 per share. The proceeds to the Company, after
deducting commissions and offering expenses, were $10,571,000. The offering also
resulted in the automatic conversion of the Series A Stock held by Genzyme into
4 million shares of Common Stock.
 
     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, and subsequent to December 31, 1995, 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).

     As of December 31, 1995, the Company has reserved 1,846,755 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

NOTE 7. EMPLOYEES 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. The option price for non-statutory
stock options must be at least 50% of fair value on the grant date. 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.
 
     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.

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 $0, $275,000, and $266,000 for the
years ended December 1993, 1994 and 1995 and $63,000 and $91,000 for the three

</TABLE>
 
     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 31, 1995, the Company had U.S. net operating loss carryforwards
("NOL") of approximately $41.5 million for income tax purposes. These
carryforwards expire through 2009. Utilization of these net operating loss
carryforwards is limited pursuant to the provisions of 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 the Company's NOL's were acquired in
connection with its acquisition of TSI and subsidiaries. Consequently, any
realization of the benefit of these purchased NOL's will be recorded as a
reduction of goodwill. In 1995, goodwill has been 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 $0, $28,000 and $238,000 in 1993, 1994 and 1995,
respectively, and $192,000 and $92,000 in the three months ended March 31, 1995

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 $1,875,000, $2,115,000 and
$3,156,000 for the years ended December 31, 1993, 1994 and 1995, respectively,
and $751,000 and $798,000 for the three months ended March 31, 1995 and 1996,
respectively. These charges represent an allocation of the Company's
proportionate share of Genzyme's overhead costs using formulas 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 paid off
in December 1995.
 
     In March 1996, the Company entered into a Convertible Debt and Development
Funding Agreement with Genzyme under which Genzyme agreed to provide a revolving
line of credit in the amount of $10 million and has agreed to fund development
costs of the AT-III program (see Note 13).
 
     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 ($32,491 per month during 1995)
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
extends through May 1996 and 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
$144,000, $310,000 and $390,000 for the years ended December 31, 1993, 1994 and
1995, respectively, and $97,000 and $190,000 for the three months ended March
31, 1996 and 1995, 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 facility 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 of $29,000, $102,000 and $169,000 for the years ended December 31,
1993, 1994 and 1995, respectively, and $42,000 and $62,000 for the three months
ended March 31, 1995 and 1996, respectively, and is committed to make annual
minimum rental payments of $92,000 in each of the years 1996 and 1997 and
$54,000 in 1998.
 
TECHNOLOGY TRANSFER AGREEMENT
 
     Under the Technology Transfer Agreement, Genzyme 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.
 
     Genzyme may not use the transferred technology or any other technology it
subsequently acquires relating to the Field except through the Company until at
least May 1, 1996. After such date, and 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 $1,072,000, $883,000 and $485,000 in
1993, 1994 and 1995, respectively, and $215,000 and $19,000 for the three months
ended March 31, 1995 and 1996, respectively.
 
     Also, see Note 5 and Note 13.
 
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 $500,000 during 1996. The Company paid Tufts
$766,000, $868,000, and $665,000 for the years ended December 31, 1993, 1994 and
1995, respectively, and $59,000 and $170,000 for the three months ended March
31, 1995 and 1996, 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. 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. Under the arrangement the Company
recognized revenues of $2,065,000, $2,947,000 and $3,874,000 for the years ended
December 31, 1993, 1994 and 1995, respectively, and $727,000 and $182,000 for
the three months ended March 31, 1995 and 1996, respectively. 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%. In addition, assuming the achievement of certain
milestones, the partners will contribute additional funds which will bring the
total contribution to $7.7 million. At December 31, 1995, the Company had
received advance payments of $155,000 from the Joint Venture.

NOTE 13. SUBSEQUENT EVENTS
 
     In February 1996, the Company obtained a short-term loan in the amount of
$950,000 from Genzyme. The loan is due on March 31, 1996 and accrues interest at
a rate of 6 1/2% per annum.
 
     On March 28, 1996 the Company entered into a Convertible Debt and
Development Funding Agreement with Genzyme under which Genzyme agreed to provide
a revolving line of credit 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.
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.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
Genzyme Transgenics Corporation:
 
     We have audited the accompanying consolidated balance sheets of TSI
Corporation as of July 3, 1994 and September 30, 1994 and the related
consolidated statements of operations, cash flows and stockholders' equity for
the fiscal year ended July 3, 1994 and the period from July 4 to September 30,
1994, respectively. These financial statements are the responsibility of
management. Our responsibility is to express an opinion of 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.
 
     As discussed in Notes 1 and 6 to the consolidated financial statements, TSI
Corporation was acquired by Genzyme Transgenics Corporation (GTC) on October 1,
1994 and has been operated by the management of GTC since that date. The
transaction involved the exchange of 4,367,601 shares of GTC common stock with a
market value of approximately $14,741,000 at the date of acquisition for all the
outstanding shares of TSI Corporation.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of TSI Corporation
as of July 3, 1994 and September 30, 1994 and the consolidated results of its
operations and its cash flows for the fiscal year ended July 3, 1994 and the
period from July 4 to September 30, 1994 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
              (ALL TABULAR $ IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1. NATURE OF BUSINESS:
 
     TSI Corporation (together with its subsidiaries, "TSI") is a leading
provider of preclinical, toxicology and human clinical testing services to
pharmaceutical, biotechnology, medical device and chemical companies. TSI also
manufactures certain biological products that it markets to diagnostic companies
and research organizations.
 
     The accompanying financial statements have been presented on the assumption
that TSI is a going concern. TSI has incurred significant losses and negative
operating cash flows in the fiscal year ended July 3, 1994 and the period from
July 4 to September 30, 1994. TSI had negative working capital of $6,002,000 and
$8,537,000 at July 3, 1994 and September 30, 1994, respectively.
 
     In fiscal year 1993, TSI restructured certain operations to reduce general
and administrative expenses and increase revenues from continuing operations.
During fiscal year 1994, TSI enacted an operating plan to reduce further general
and administrative expenses by centralizing common functions within operating
divisions, reengineering operating processes and commonizing to the extent
possible within its laboratories.
 
     On October 1, 1994, TSI was acquired by Genzyme Transgenics Corporation
("GTC") (see Note 13).
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of TSI and its
wholly-owned subsidiaries. All significant intercompany transactions have been
eliminated. Overseas subsidiaries have been consolidated using a fiscal year-end
of May 31. Effective for fiscal 1994, TSI changed the fiscal year-end of its
U.K. subsidiary, G.D.R.U. Limited ("GDRU"), from May 31 to a 52/53 week year-end
coinciding with its domestic operations. Therefore, the accompanying
consolidated statement of operations for the fiscal year ended July 3, 1994
includes the operating results of GDRU for the twelve-month period ended May 31,
1994. The consolidated statement of cash flows for the fiscal year ended July 3,
1994 includes the cash flows of GDRU for the thirteenth-month period ending July
3, 1994. For the month of June 1994, GDRU had revenues of $761,000 and earned
net income of $202,000 which is reflected as an adjustment to retained earnings.
 
CASH EQUIVALENTS
 
     Cash equivalents are stated at cost, which approximates market, and have
original maturities of three months or less.
 
INVENTORY
 
     Inventory is valued at lower of cost or market (first-in, first-out
method).
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property 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
remaining term of the lease.

July 3, 1994 and the period from July 4 to September 30, 1994 was $303,000 and
$54,000, respectively.

REVENUE RECOGNITION
 
     For both services and research and development revenues TSI 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 revenues are generally recognized upon
shipment. Research and development revenues in fiscal 1994 consisted of $682,000
from Exemplar Corporation ("Exemplar"), a research and development company
formed in 1991 (see Note 12).
 
     Profits expected to be realized on contracts are based on TSI's estimates
of total contract sales value and 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 contract-related
revenues, the full amount of the anticipated contract loss is immediately
recognized. Total contract loss reserves at July 3, 1994 and September 30, 1994
were $1,934,000 and $2,007,000, respectively.

TRANSLATION OF FOREIGN CURRENCIES
 
     Assets and liabilities of foreign subsidiaries are translated at year-end
exchange rates, and statement of operations accounts are translated at average
exchange rates. Resulting translation adjustments are recorded in a separate
component of stockholders' equity, "Accumulated translation adjustment."
 
INCOME TAXES
 
     TSI follows the asset and liability method of accounting for income taxes
as set forth in Statement of Financial Accounting Standards No. 109 ("FAS 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.
 
NET LOSS PER COMMON SHARE
 
     Net loss per share is computed by dividing the net loss by the weighted
average number of common shares and common stock equivalents outstanding when
the effect would be dilutive. Common stock equivalents include stock options.
The difference between weighted average shares for primary and fully diluted net
loss per share was not significant for the periods presented.
 
3. LOSS ON DISPOSAL OF ASSETS:
 
     In March 1993, TSI recorded a charge of $1,320,000 in connection with the
planned disposal of the Laboratory Animal Services ("LAS") and The TSI Center
for Diagnostic Products ("CDP") operations. In September 1993, TSI announced a
$5 million disposal of operations charge to reduce the net assets of its German
preclinical testing and regulatory consulting subsidiary, IBR Forschungs GmbH
("IBR"), to net realizable value. Operations at IBR ceased during the second
quarter of fiscal 1994 and on December 1, 1993 it entered into liquidation
proceedings. At July 3, 1994 and September 30, 1994, IBR's remaining net assets
of $808,000 and $485,000, respectively, primarily working capital and property,
plant and equipment, have been classified as net assets held for sale in the
accompanying consolidated balance sheets and represent the net realizable value
of these assets upon their disposition.
 
4. WRITEDOWN OF COSTS IN EXCESS OF NET ASSETS ACQUIRED AND RESTRUCTURING CHARGE:
 
     In March 1993, the Board of Directors replaced several members of TSI's
executive management group, including the chief executive officer, in
conjunction with a review and evaluation of the performance of TSI's various
business units. At that time, TSI announced a restructuring of certain
operations, principally the Health and Sciences Research, Inc. ("HSRI")
subsidiary. Since improved operating results were not imminent, TSI determined
that the HSRI operation could not compete profitably as a provider of clinical
services for all four phases of the clinical testing marketplace and decided to
refocus the HSRI operations on the phase II and III markets only. The other HSRI
services were discontinued and the related personnel and facilities considered
redundant. Given the initial losses incurred from the date of purchase and the
expected future cash requirements if operations were not reduced, TSI determined
that the original goodwill associated with the purchase of HSRI was worthless.
The majority of the writedown and restructuring charge recorded in fiscal 1993
represented costs associated with the HSRI operation.
 
     In May 1994, TSI reached agreement with a landlord securing the termination
of the lease of its former corporate offices and research and development
facility which was originally scheduled to expire on June 30, 2001. The lease
termination was effective May 31, 1994. Additionally, in May 1994, TSI reached
an agreement settling an arbitration claim against the former owner of HSRI.
Under the terms of the settlement,

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED
 
the former owner agreed to pay TSI $1 million which was recorded as a gain in
the fourth quarter of fiscal 1994, of which $650,000 was paid at the date of
agreement, $100,000 was received on September 9, 1994 and $250,000 was received
on December 9, 1994.
 
     In May 1994, TSI further restructured its HSRI operations which continued
to incur operating losses following the restructuring in March 1993. As a result
of this action, TSI provided an $854,000 restructuring charge in the fourth
quarter of fiscal 1994. This charge consisted principally of costs for
relocating and reducing HSRI's facilities. The exit costs recognized for this
transaction were severance of $106,000 for the termination of sixteen employees
and lease obligations on a vacated facility of $748,000. Severance in the amount
of $40,000 was charged to the reserve during fiscal 1994. In addition, TSI
reduced its estimated restructuring reserve requirement by $624,000. The
$770,000 net amount of these transactions is reflected as an offset to other
operating expenses.
 
     As of September 30, 1994, there was $1,044,000 of accrued restructuring
remaining, of which $508,000 was classified as long-term. During the period from
July 4 to September 30, 1994, $53,000 was paid out of accrued restructuring for
severance and $111,000 was paid for the facility lease.
 
5. ACQUISITIONS:
 
     Effective July 1, 1991, TSI acquired all of the common stock of Argus
Research Laboratories, Inc. and The Center for Photobiology at Argus, Inc., two
privately-held preclinical testing companies located in Horsham, Pennsylvania
(collectively, "Argus") for $2.0 million in cash. TSI has accounted for these
acquisitions using the purchase method. In addition to the purchase price, TSI
entered into a 10-year noncompete agreement with the principal stockholder of
Argus for a total of $750,000. TSI paid $375,000 at the acquisition date and is
obligated to pay $25,000 per year at the end of years 1-5 and $50,000 per year
at the end of years 6-10. The excess of the total acquisition costs over the
fair value of net assets acquired was $1,750,000 which was written off in
conjunction with the 1994 restructuring (see Note 4).
 
6. COMMITMENTS AND CONTINGENCIES:
 
     TSI leases equipment and facilities under various operating and capital
leases (see also Note 7). The deferred lease obligation represents the
cumulative difference between actual facility lease payments and lease expense
recognized ratably over the lease period.
 
     At July 3, 1994 and September 30, 1994, the total cost of equipment under
capital lease was $1,872,000 and $2,309,000, respectively, with $374,000 and
$302,000, respectively, of accumulated depreciation.
 
     Rent expense for the fiscal year ended July 3, 1994 and the period from
July 4, to September 30, 1994 was approximately $2,030,000 and $195,000,
respectively.

     On June 17, 1994, a lawsuit was filed by a stockholder of TSI against TSI,
GTC and the directors of TSI alleging, among other things, that the terms of the
merger agreement are unfair to TSI's stockholders and that TSI's directors
breached their fiduciary duties in authorizing TSI to enter into the merger
agreement. The lawsuit seeks an unspecified amount of damages and a court order
to enjoin the merger. Each of the directors of TSI, TSI and GTC deny the
allegations and continue to believe that the merger is fair to, and in the best
interests of, the stockholders of TSI. They intend to vigorously defend the
lawsuit. The plaintiffs did not actually file a motion for a preliminary
injunction and the merger was consummated on October 1, 1994. No further
proceedings in the litigation have occurred since that time.
 
7. BORROWINGS:
 
     TSI has a revolving line of credit arrangement with a commercial bank. In
October 1993, the bank provided TSI with a commitment to extend the revolving
line of credit until August 1, 1994. Under the terms of the extension, TSI
continued to have a $1 million standby letter of credit and could borrow up to
70 percent of the amount of the eligible accounts receivable of its U.S.
subsidiaries, subject to a maximum borrowing of $2 million. In consideration for
the extension, TSI agreed to pay a fee of $100,000 payable at the rate of
$10,000 per month from October 1993 to April 1994 with the balance due in August
1994. In addition, TSI issued the bank 20,000 shares of TSI's common stock and a
warrant to purchase an additional 188,000 shares of common stock exercisable at
$0.01 per share. The warrant became exercisable as to 40,000 shares on March 27,
1994, 58,000 shares on July 3, 1994 and 90,000 shares on July 8, 1994.
 
     In June 1994, the bank agreed to modify and extend the existing credit
agreement through August 1, 1995. Under the terms of the extension, TSI could
borrow up to $3 millon based upon 75% of eligible accounts receivable. The
amount of the bank line decreased to $2 million on December 31, 1994. In
addition, the bank agreed to increase the existing standby letter of credit from
$1.0 million to $1.5 million prior to June 30, 1994. As of September 30, 1994,
TSI was in compliance with the amended covenants. Amounts outstanding under the
line of credit were $2,320,000 as of September 30, 1994. No amounts were due
under the standby letter of credit as of September 30, 1994.
 
     Under the terms of the bank line of credit, TSI has agreed not to pay any
dividends until the loans have been repaid.
 
     In September 1994, TSI received a $2 million lease line with a commercial
leasing company. Leases require monthly payments over 36 months at 10% with a
fair market value buyout (in the range of 5% to 10% of original cost) at the end
of the lease term. The Lease Agreement required a 25% cash deposit at inception.
As of September 30, 1994, $1,956,000 of the lease line had been utilized.

respectively.
 
8. STOCKHOLDERS' EQUITY:
 
COMMON STOCK AND WARRANTS
 
     In May 1990, TSI issued Class D warrants for 100,000 shares of common stock
to Biogen, Inc. in exchange for certain technology. Each warrant allows the
holder to purchase one share of common stock at $3.61, subject to adjustment.
The warrants expire on May 31, 1995. As of September 30, 1994, 16,851 Class D
Warrants were exercised.
 
     In September 1991, TSI issued warrants to purchase 640,000 shares of common
stock in connection with the equity financing of Exemplar Corporation. Each
warrant allows the holder to purchase one share of TSI common stock for $8.00
per share and is exercisable until January 31, 1996.
 
     In connection with the refinancing of TSI's line of credit in October 1993,
TSI has issued the bank 20,000 shares of TSI's common stock and a warrant to
purchase an additional 188,000 shares of common stock which became exercisable
at $0.01 per share in July 1994. TSI recorded a charge during fiscal 1994 of
$298,000 in connection with these issuances.
 
     As of September 30, 1994, TSI has reserved 3,965,125 shares of common
stock, subject to adjustment, for future issuance under the various classes of
warrants, convertible preferred stock and stock option and employee stock
purchase plans (see Note 9).

CONVERTIBLE PREFERRED STOCK
 
     On May 2, 1989, the effective date of TSI's initial public offering, the
Board of Directors authorized the issuance of convertible preferred stock, $0.01
par value, on a pro rata basis to holders of common stock on that date.
Convertible preferred shareholders have no voting rights, are not entitled to
dividends, and have a liquidation preference of $0.01 per share.
 
     Each share of convertible preferred stock became convertible into one share
of common stock upon the achievement of certain targeted market values of TSI's
common stock, as defined. On July 1, 1995, TSI may redeem all shares then
outstanding at par value. During fiscal 1992, all outstanding shares of
convertible preferred stock became eligible for conversion at the option of the
holders thereof and, as of September 30, 1994, 2,013,716 shares had been
converted into common stock and 46,640 shares had been canceled.
 
SHAREHOLDERS' RIGHTS PLAN
 
     In February 1991, the Board of Directors adopted a Shareholder Rights Plan
which provided for a dividend distribution of one preferred share purchase right
for each share of common stock outstanding on March 1, 1991. Under certain
circumstances, each right entitles the holder to purchase from TSI 1/100 of a
new series of preferred stock, designated Series A Junior Participating
Preferred Stock, at a price of $19.80 per 1/100 of a share.
 
     The rights are not exercisable and cannot be transferred separately from
the common stock until ten days after (i) a person acquires 20% or more (other
than in an Approved Transaction, as defined) or makes a tender offer for 30% or
more of TSI's common stock, or (ii) TSI's Board of Directors shall declare a
person owning 10% or more of TSI's Common Stock to be an Adverse Person, as
defined.
 
     If, after the rights become exercisable, (i) TSI is the surviving entity in
a merger with a 20% or more stockholder, (ii) a 20% or more stockholder engages
in certain "self-dealing" transactions with TSI, (iii) any person acquires 30%
or more of TSI's common stock without a plan approved by TSI's Board of
Directors or (iv) a 20% or more stockholder increases such ownership percentage
through recapitalization or reclassification of securities, each right not owned
by such person will entitle its holder to purchase, at the right's exercise
price, common stock having a value of two times the exercise price of the right.
 
     In addition, if TSI either (i) is acquired in a merger or other business
combination in which TSI is not the surviving entity, or (ii) sells or transfers
50% or more of its assets or earning power to another party, each right will
entitle its holder to purchase, upon exercise, common stock of the acquiring
company having a value equal to two times the exercise price of the right. The
rights expire on February 28, 2001 unless redeemed by TSI for $0.01 per right at
any time prior to the tenth day following a person's acquisition of 20% or more
of TSI's common stock.
 
     Preferred shares purchasable upon exercise of the rights will be entitled
to a minimum quarterly dividend of $1 per share, or 100 times any dividend
declared on common stock, and will have a minimum liquidation preference of $100
per share, or 100 times any liquidation payment made to common stock. So long as
the rights are not separately transferable, TSI will issue one right with each
new share of common stock issued.

     Due to the uncertainty surrounding the realization of these favorable tax
attributes in future income tax returns, TSI has placed a valuation allowance
against its otherwise recognizable deferred tax assets.
 
     TSI had U.S. net operating loss (NOL) carryforwards of approximately $33
million and $35 million at July 3, 1994 and September 30, 1994, respectively.
These loss carryforwards expire through 2008. Utilization of these NOL's are
limited pursuant to the provisions of Section 382 of the Internal Revenue Code
of 1986 and to the extent that the Separate Return Limitation Year (SRLY) rules
apply.

12. RESEARCH AND DEVELOPMENT AGREEMENT:
 
     In June 1991, the company entered into a research and development agreement
with Exemplar to perform specific research programs on behalf of Exemplar. The
agreement provided for TSI to license certain technology rights to Exemplar for
$300,000. Under the agreement, total research and development funding including
license fees would not exceed $7.5 million.
 
     On September 27, 1991, Exemplar completed the sale of $8 million of its
callable common stock. In connection with the equity financing of Exemplar, TSI
issued warrants to purchase 646,000 shares of TSI common stock at $8.00 per
share in return for the option to purchase all of the outstanding common stock
of Exemplar at prices which increase over time to a maximum of $33 million. The
warrants and options are exercisable from July 1, 1992 through January 31, 1996.
 
     In November 1993, TSI reached an agreement with Exemplar to terminate TSI's
obligations under the research and development agreement as well as its option
to purchase the stock of Exemplar. As part of the termination agreement, TSI's
research and development group was transferred to Exemplar. Accordingly, TSI
does not expect any significant research and development revenues and expenses
in the future.
 
     In early fiscal 1994, TSI recognized approximately $682,000 of research and
development revenues under the Exemplar agreement. There was no revenue under
this agreement in the period from July 4 to September 30, 1994.
 
13. SUBSEQUENT EVENT:
 
     On October 1, 1994, TSI was acquired by GTC in a merger transaction in
which GTC issued two-tenths (0.2) of one share of GTC common stock for each
share of TSI common stock resulting in the issuance of approximately 4,367,600
shares of the GTC's common stock. The transaction was accounted for as a
purchase.
 
     In connections with TSI's acquisition agreement with GTC, GTC entered into
agreements with certain creditors of TSI and its subsidiaries under which GTC:

     -- guaranteed TSI's $1.5 million standby letter of credit to a landlord of
        a TSI subsidiary;
 
     -- guaranteed TSI's outstanding equipment lease obligations to certain
        equipment lessors (approximately $1.9 million at September 30, 1994);
        and
 
     -- guaranteed the sums due under a promissory note issued by TSI in the
        principal amount of $800,000.
 
     In addition, as required by TSI's lender, GTC agreed to guarantee, upon
completion of the merger, TSI's obligation under a $3.0 million revolving credit
agreement (that will decrease to $2.0 million on December 31, 1994) due August
1, 1995.

Board of Directors and Stockholders
TSI Corporation
 
     We have audited the accompanying consolidated balance sheet of TSI
Corporation as of June 27, 1993 and the related consolidated statements of
operations, stockholders' equity, and cash flows for the year then ended. 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 audit.
 
     We conducted our audit 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 audit provides 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
TSI Corporation at June 27, 1993 and the consolidated results of its operations
and its cash flows for the year then ended, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
  YEAR ENDED JUNE 27, 1993 (ALL TABULAR $ IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1. NATURE OF BUSINESS
 
     TSI Corporation (together with its subsidiaries, TSI) is a leading provider
of preclinical, toxicology and human clinical testing services to
pharmaceutical, biotechnology, medical device and chemical companies. TSI also
manufactures certain biological products that it markets to diagnostic companies
and research organizations.
 
     The accompanying financial statements have been presented on the assumption
that TSI is a going concern. TSI has incurred significant losses and incurred
negative operating cash flows in the fiscal year ended June 27, 1993. TSI had
negative working capital of $3.4 million as of June 27, 1993.
 
     During fiscal 1994, TSI enacted an operating plan to reduce general and
administrative expenses by centralizing common functions within operating
divisions, reengineering operating processes and commonizing to the extent
possible within its laboratories. Management intends to continue to implement
further centralization and productivity improvements in the future. As a result
of the actions described above, coupled with the refinancing of the credit line,
as described in Note 14, management expects that TSI will be able to meet its
financial obligations at a minimum through fiscal 1995.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The consolidated financial statements include the accounts of TSI and its
wholly owned subsidiaries. All significant intercompany transactions have been
eliminated. To assist in the consolidation of the financial statements, overseas
subsidiaries have been consolidated using a fiscal year end of May 31. The
effect of intervening events between May 31, 1993 and TSI's year end are not
material to the financial statements.
 
CASH EQUIVALENTS
 
     Cash equivalents are stated at cost which approximates market and have
original maturities of three months or less.
 
SHORT-TERM INVESTMENTS
 
     Short-term investments are stated at lower of cost or market.
 
INVENTORY
 
     Inventory is valued at lower of cost or market (first in, first out method)
and at June 27, 1993 consisted solely of raw materials.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost and depreciated using the
straight-line method over estimated useful lives of five to thirty years.
Leasehold improvements are amortized using the straight-line method over the
remaining term of the lease.

</TABLE>
 
COSTS IN EXCESS OF NET ASSETS ACQUIRED
 
     The excess consideration paid and costs incurred over the net value of
assets acquired is being amortized over a 30-year period. The carrying value of
goodwill is periodically reviewed by management. Currently, expected operating
results of each entity for which goodwill has been recorded is compared with the
anticipated results of operations at the time of acquisition. When material
adverse changes in operations are noted, management will then determine the
amount by which the related goodwill has been impaired. Accumulated amortization
as of June 27, 1993 was $784,000. In 1993, TSI wrote off $9,586,000 of such
costs as part of the restructuring (See Note 4).
 
REVENUE RECOGNITION
 
     For both services and research and development revenues, TSI accounts for
cost reimbursement contracts and fixed price contracts using the percentage of
completion method. TSI measures the progress of its contracts by comparing the
costs incurred to date to total estimated contract costs of completion. All
indirect costs, including general and administrative expenses, associated with
the completion of the contracts are allocated to individual contracts based on
direct labor incurred by contract. Unbilled contract revenue represents
recoverable costs and fees on cost reimbursement contracts which had not been
billed at the balance sheet date. Fees withheld (retainage) included in unbilled
revenue were approximately $38,354 as of June 27, 1993. Product revenue is
generally recognized upon shipment.
 
TRANSLATION OF FOREIGN CURRENCIES
 
     Assets and liabilities of foreign subsidiaries are translated at year-end
exchange rates, and statement of operations accounts are translated at average
exchange rates. Resulting translation adjustments are recorded in a separate
component of stockholders' equity, "Accumulated translation adjustments".
 
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.
 
3. LOSS ON DISPOSAL OF ASSETS
 
     In March 1993, TSI recorded a charge of $1,320,000 in connection with the
planned disposal of the LAS and CDP operations. In the fourth quarter of fiscal
1993, TSI recorded an additional charge of $5,007,000 relating to the writeoff
of net assets of IBR, resulting in a total loss on disposal for fiscal 1993 of
$6,327,000 (see Note 14). The charge reflects the expected loss from the
disposition of net assets and anticipated operating losses through the estimated
dates of disposal. At June 27, 1993, certain of the assets of LAS had been sold,
while the remainder is expected to be disposed of in July 1993. TSI continues to
pursue

opportunities to sell its CDP operations and anticipates its disposition in
fiscal 1995. The remaining net assets of these operations of $2,215,000,
primarily working capital and property, plant and equipment, have been
reclassified to net assets held for sale in the accompanying consolidated
balance sheet, and represent the estimated net realizable value of these assets
upon disposition.
 
4. WRITEDOWN OF COSTS IN EXCESS OF NET ASSETS ACQUIRED AND
   RESTRUCTURING CHARGE
 
     In March 1993, the Board of Directors replaced several members of TSI's
executive management group, including the Chief Executive Officer, in
conjunction with a review and evaluation of the performance of TSI's various
business units. At that time, TSI announced a restructuring of certain
operations, principally the HSRI subsidiary. For the first nine months of
operation after its acquisition, HSRI had net revenues of $4.5 million, and
incurred a $900,000 operating loss, exclusive of $1.7 million of contract losses
provided for at the date of acquisition. The loss resulted from the expansion of
HSRI's operations to match anticipated revenue substantially in excess of actual
revenues. Since improved operating results were not imminent, TSI determined
that the HSRI operation could not compete profitably as a provider of clinical
services for all four phases of the clinical testing marketplace and decided to
re-focus the HSRI operation on the Phase II and III markets only. The other HSRI
services were discontinued and the related personnel and facilities considered
redundant. Given the initial losses incurred from the date of purchase, and the
expected future cash requirements if operations were not reduced, TSI determined
that the original goodwill associated with the purchase of HSRI was worthless.
Management's determination was based principally on the fact that anticipated
revenues and related profitability, included in management's assessment of the
purchase price which generated the goodwill, were not realizable from HSRI's
operations. As a result, TSI wrote down the carrying value of costs in excess of
net assets acquired by $9,586,000 and provided $6,061,000 for restructuring
costs during the year ended June 27, 1993. The restructuring charge consisted
principally of $2,000,000 for the relocation and consolidation of various
facilities, $1,001,000 for severance costs, $900,000 for estimated losses on
certain contracts and a write-down of $600,000 for certain intangible assets.
The majority of the write down and restructuring charge, approximately
$8,000,000, represents costs associated with the HSRI operation.
 
5. ACQUISITIONS
 
     Effective July 1, 1991, TSI acquired all of the common stock of Argus
Research Laboratories, Inc. and The Center for Photobiology at Argus Inc., two
privately held preclinical testing companies located in Horsham, Pennsylvania
(collectively, "Argus"), for $2.0 million in cash. TSI has accounted for these
acquisitions using the purchase method. In addition to the purchase price, TSI
entered into a 10-year non-compete agreement with the principal stockholder of
Argus for a total of $750,000. TSI paid $375,000 at the acquisition date and is
obligated to pay $25,000 per year at the end of years 1-5 and $50,000 per year
at the end of years 6-10. The excess of the total acquisition cost over the fair
value of net assets acquired was $1,750,000 which was written off in conjunction
with the restructuring (see Note 4).
 
     In December 1990, TSI acquired CDP for 585,546 shares of TSI's common stock
(fair market value of $2,000,000 at the acquisition date). CDP is a manufacturer
of diagnostic intermediates, including human bulk serum, plasma derived serums,
and other products used in the manufacture of human diagnostics. The transaction
was accounted for using the pooling of interests method. In fiscal 1993, TSI
announced a plan to sell CDP and has provided for a loss in connection with this
sale (see Note 3).
 
     In October 1991, TSI acquired GDRU for 1,055,555 shares of TSI's common
stock (fair market value of approximately $13,000,000 at the acquisition date).
GDRU is a leading provider of Phase I human clinical contract testing services
in the United Kingdom. The transaction was accounted for using the pooling of
interests method. During fiscal 1991, GDRU acquired 33% of the common stock of
Centre du Recherche Sur le Medicament Toulouse Midi-Pyrenees (CRM) for
approximately $155,000. The acquisition was accounted for under the equity
method. In July 1991, GDRU acquired an additional 30% interest in CRM for

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
approximately $107,000 and subsequently consolidated the accounts of CRM. In
fiscal 1993, TSI wrote off the investment in CRM and has included this charge in
the restructuring charge (see Note 4). Operations at CRM were discontinued in
1993.
 
     Effective March 31, 1992 TSI acquired all of the shares of PharmaKinetics
Laboratories (Deutschland) GmbH (IBR) for $1,950,000 cash and 158,528 shares of
TSI's common stock (fair market value $991,000 at the date of acquisition). The
acquisition was accounted for under the purchase method. The excess of the total
acquisition cost over the fair value of net assets acquired was $1,328,000. The
net assets of IBR were written off in the fourth quarter of fiscal 1993 (see
Note 3).
 
     Effective June 29, 1992, TSI acquired all of the common stock of Health and
Sciences Research Incorporated (HSRI) for $6,000,000 cash. The acquisition was
accounted for under the purchase method. The excess of the total acquisition
cost over the fair value of net assets acquired was $8,405,000. HSRI's operating
results for all of fiscal 1993 are included in the June 27, 1993 statement of
operations. In fiscal 1993, TSI wrote off the remaining excess of the total
acquisition cost over the fair value of the net assets acquired as part of the
restructuring (see Note 4).
 
6. LEASE COMMITMENTS
 
     TSI leases equipment and facilities under various operating and capital
leases. The deferred lease obligation represents the cumulative difference
between actual facility lease payments and lease expense recognized ratably over
the lease period.
 
     At June 27, 1993, TSI's future minimum payments required under these leases
are as follows:

     In 1993, TSI incurred $1,134,000 of capital lease obligations in connection
with the acquisition of certain capital equipment. At June 27, 1993, the total
cost of equipment under capital lease was $2,303,000 with $445,000 of
accumulated depreciation.
 
     Rent expense for the year ended June 27, 1993 was approximately $2,675,000.
 
7. BORROWINGS
 
     In September 1991, TSI entered into a one-year revolving line of credit
arrangement with a commercial bank. The line of credit allowed for TSI to borrow
up to $4,000,000 at the bank's base lending rate plus 1/2%, through September
30, 1992. The line of credit was extended to October 31, 1992 and was
renegotiated for a one-year period allowing TSI to borrow up to $7,000,000 at
the bank's base lending rate plus 1% through October 29, 1993.
 
     As of March 28, 1993, TSI was in default of several covenants under this
bank line of credit. The bank agreed to waive such defaults in connection with
an agreement amending the line of credit to make it payable

on demand by the bank, to require the bank's approval for any future advances
and to increase the interest rate effective April 1, 1993 to the bank's base
lending rate plus 2%. The line is secured by the inventory, accounts receivable,
patents and trademarks of TSI and its U.S. subsidiaries, and a pledge of the
capital stock of its U.S. subsidiaries and GDRU. As of June 27, 1993, TSI was in
compliance with the amended covenants and had borrowed the maximum amount
available under the line.
 
     Amounts outstanding under the line of credit aggregated $2,000,000 as of
June 27, 1993. In addition, the bank issued a $1,000,000 standby letter of
credit under the line of credit in December 1992. No amounts were due under the
letter of credit as of June 27, 1993.
 
     Subsequent to June 27, 1993, TSI refinanced its revolving line of credit
(see Note 14).
 
     TSI's long-term debt at June 27, 1993 consisted of the following:

8. STOCKHOLDERS' EQUITY
 
COMMON STOCK AND WARRANTS
 
     In connection with its initial public offering in May 1989, TSI provided
the underwriter with a Unit Purchase Option to purchase, after subsequent
adjustments, up to 88,210 units (each unit consisting of three shares of common
stock and two Class A Warrants) at $4.75 per unit subject to adjustment. Each

Warrant entitles the holder to purchase one share of common stock and two Class
B Warrants at a total price of $2.00, subject to adjustment, at any time after
the date of issuance until May 1994. Each Class B Warrant entitles the holder to
purchase one share of common stock at a price of $3.35, subject to adjustment,
at any time through May 1994. In March 1992, 218,868 shares of common stock were
issued pursuant to the exercise of 64,905 Unit Purchase Options and 23,900 Class
A Warrants attached thereto. An additional 11,986 shares of common stock were
issued in December 1992 pursuant to the exercise of an additional 396 Unit
Purchase Options, including all Class A and Class B Warrants attached thereto,
as well as 8,422 Class A Warrants which were attached to Unit Purchase Options
exercised in March 1992. At June 27, 1993, 22,909 Unit Purchase Options, 97,347
Class A Warrants, and 64,926 Class B Warrants were outstanding.
 
     In May 1990, TSI issued Class D Warrants for 100,000 shares of common stock
to Biogen, Inc. in exchange for certain technology. Each warrant allows the
holder to purchase one share of common stock at $3.61, subject to adjustment.
The warrants expire on May 31, 1995. In February 1992, 16,851 Class D Warrants
were exercised.
 
     In March and April 1991, substantially all of the Class B Warrants that
were issued in conjunction with TSI's initial public offering, the Class C
Warrants issued in conjunction with the financing of the Mason acquisition and
TSI's Class E Warrants were exercised. In addition, the 746,269 shares of
redeemable convertible preferred stock also issued in conjunction with the Mason
acquisition were exchanged for an equal number of shares of common stock.
 
     In September 1991, TSI issued warrants to purchase 640,000 shares of common
stock in connection with the equity financing of Exemplar Corporation. Each
warrant allows the holder to purchase one share of TSI common stock for $8.00
per share and is exercisable until January 31, 1996.
 
     During 1988 and 1989, TSI issued restricted shares of common stock to
employees, consultants, directors, scientific advisors and others at fair market
value on the date of grant. Generally, these shares vest ratably over five
years. These shares are restricted by terms of employee stock purchase
agreements between TSI and the stockholder under which TSI has the right to
repurchase any unvested restricted shares at their original purchase price. As
of June 27, 1993, there were 71,123 of these restricted shares outstanding, of
which 70,396 were vested.
 
     In connection with the anticipated refinancing of TSI's line of credit in
October 1993, TSI has agreed to issue 208,000 shares of common stock to a
commercial bank.
 
     As of June 27, 1993, TSI has reserved 3,433,332 shares of common stock,
subject to adjustment, for future issuance under the various classes of
warrants, convertible preferred stock, Unit Purchase Options, Stock Option and
Employee Stock Purchase Plans (see Note 9).
 
CONVERTIBLE PREFERRED STOCK
 
     On May 2, 1989, the effective date of TSI's initial public offering, the
Board of Directors authorized the issuance of convertible preferred stock, $.001
par value, on a pro rata basis to holders of common stock on that date.
Convertible preferred shareholders have no voting rights, are not entitled to
dividends, and have a liquidation preference of $.001 per share.
 
     Each share of convertible preferred stock became convertible into one share
of common stock upon the achievement of certain targeted market values of TSI's
common stock, as defined. On July 1, 1995, TSI may redeem all shares then
outstanding at par value. During fiscal 1992, all outstanding shares of
convertible preferred stock became eligible for conversion at the option of the
holders thereof, and as of June 27, 1993, 1,964,950 shares had been converted
into common stock.

                                TSI CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     In November 1990, TSI increased the authorized shares of preferred stock
from 2,070,000 shares to 25,000,000 shares, changed the par value from $.001 to
$.01 per share, and established the convertible preferred stock as a series of
the preferred stock.
 
SHAREHOLDERS' RIGHTS PLAN
 
     In February 1991, the Board of Directors adopted a Shareholder Rights Plan
which provided for a dividend distribution of one preferred share purchase right
for each share of common stock outstanding on March 1, 1991. Under certain
circumstances, each right entitles the holder to purchase from TSI 1/100 of a
new series of Preferred Stock, designated Series A Junior Participating
Preferred Stock, at a price of $19.80 per 1/100 of a share.
 
     The rights are not exercisable and cannot be transferred separately from
the common stock until ten days after (i) a person acquires 20% or more (other
than in an Approved Transaction), or makes a tender offer for 30% or more of
TSI's common stock, or (ii) TSI's Board of Directors shall declare a person
owning 10% or more of TSI's Common Stock to be an Adverse Person.
 
     If, after the rights become exercisable, (i) TSI is the surviving entity in
a merger with a 20% or more stockholder, (ii) a 20% or more stockholder engages
in certain "self-dealing" transactions with TSI, (iii) any person acquires 30%
or more of TSI's common stock, without a plan approved by TSI's Board of
Directors or (iv) a 20% or more stockholder increases such ownership percentage
through recapitalization or reclassification of securities, each right not owned
by such person will entitle its holder to purchase, at the right's exercise
price, common stock having a value of two times the exercise price of the right.
 
     In addition, if TSI either (i) is acquired in a merger or other business
combination in which TSI is not the surviving entity, or (ii) sells or transfers
50% or more of its assets or earning power to another party, each right will
entitle its holder to purchase, upon exercise, common stock of the acquiring
company having a value equal to two times the exercise price of the right. The
rights expire on February 28, 2001 unless redeemed by TSI for $.01 per right at
any time prior to the tenth day following a person's acquisition of 20% or more
of TSI's common stock. Preferred shares purchasable upon exercise of the rights
will be entitled to a minimum quarterly dividend of $1 per share, or 100 times
any dividend declared on common stock, and will have a minimum liquidation
preference of $100 per share or 100 times any liquidation payment made to common
stock. So long as the rights are not separately transferable, TSI will issue one
right with each new share of common stock issued.
 
9. EMPLOYEES BENEFIT PLANS
 
STOCK OPTION PLAN
 
     Under TSI's 1988 Amended and Restated Stock Option Plan (the "1988 Plan"),
incentive stock options and non-qualified options to purchase common shares may
be issued to key employees, directors, and consultants at the discretion of the
Stock Option Committee. The 1988 Plan was amended on November 21, 1991 to
increase the number of shares that may be subject to options under the plan from
1,400,000 to 2,100,000 shares. As of June 27, 1993, TSI had available 72,685
shares for the grant of options under the 1988 Plan. These options are issued at
the fair market value on the date of grant and vest over periods of up to five
years.

1991 DIRECTOR STOCK OPTION PLAN
 
     Under TSI's 1991 Director Stock Option Plan (the "Director Plan"),
non-qualified options to purchase common stock are automatically granted to
non-employee directors on the date of each director's election or reelection to
the board of directors at the annual rate of 5,000 shares per year, subject to
reduction for periods in which options previously granted under the 1988 Stock
Option Plan first become exercisable. Options under the Director Plan may be
granted with respect to a maximum of 150,000 shares of TSI's common stock. The
options become exercisable over five years at an exercise price equal to 100% of
the fair market value of the common stock on the date of grant. As of June 27,

STOCK PURCHASE PLAN
 
     The 1991 Employee Stock Purchase Plan (the "1991 Purchase Plan") authorized
the grant of rights to purchase shares of common stock to eligible employees at
the discretion of TSI's Board of Directors.
 
     The purchase price per share of common stock in an offering is 85% of the
lower of its fair market value at the beginning of the offering period or the
applicable exercise date. There are 600,000 shares of common stock which have
been authorized for issuance under this plan, of which 59,310 shares have been
issued to date. As of June 27, 1993, $117,000 had been withheld under the plan
for the offering period which ends September 30, 1993.
 
  Other
 
     TSI's U.S. employees, subject to certain eligibility requirements, can
participate in TSI's defined contribution plan. Currently, TSI may match up to
50% of each participating employee's contributions to the plan to a maximum of
3% of salary. TSI 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. In 1993, TSI recognized $300,000 of expense in connection
with the plan.

</TABLE>
 
     Loss from foreign operations before income taxes and minority interest
totaled $(3,658,000) in 1993.
 
     Deferred income taxes in the amount of $123,000 in 1993 have been provided
for differences between tax and financial statement accounting methods,
principally related to contract revenue recognition of foreign operations.
 
     At June 27, 1993, TSI had net operating loss carryforwards for financial
reporting purposes of approximately $33,000,000 and for tax purposes of
approximately $28,000,000. The difference results primarily from the write-off
of goodwill. Tax loss carryforwards expire through 2008. These carryforwards are
subject to possible limitations on annual utilization under current Internal
Revenue Service regulations.
 
     Cash paid for taxes was $80,000 in the year ended June 27, 1993.
 
     In February 1992, the Financial Accounting Standards Board issued Statement
No. 109 "Accounting for Income Taxes" (FAS 109). TSI will adopt FAS 109 in the
first quarter of fiscal 1994. Adoption of FAS 109 is not expected to have a
material effect on TSI's financial statements.

12. RESEARCH AND DEVELOPMENT AGREEMENT
 
     On June 26, 1991, TSI entered into a research and development agreement
with Exemplar Corporation ("Exemplar"), a newly formed company, to perform
specific research programs on behalf of Exemplar. The agreement also provides
for TSI to license certain technology rights to Exemplar for $300,000. Total
research and development funding including license fee will not exceed $7.5
million.
 
     On September 27, 1991, Exemplar completed the sale of $8,000,000 of its
callable common stock. In connection with the equity financing of Exemplar, TSI
issued warrants to purchase 640,000 shares of TSI Common Stock at $8.00 per
share in return for the option to purchase all of the outstanding common stock
of Exemplar at prices which increase over time to a maximum of $33,000,000. The
warrants and option are exercisable from July 1, 1992 through January 31, 1996.
In fiscal 1993, TSI recognized approximately $2,662,000 of research and
development revenues including license fees under the Exemplar agreement. There
was no unbilled revenue under this agreement at June 27, 1993.
 
13. CONTINGENCY
 
     As a result of the current state of the insurance market, TSI has chosen
not to seek product liability coverage for its products. In reaching its
conclusion, management has balanced the likely costs and terms of such coverage
and its availability against the risks involved in foregoing such coverage and
the protection such coverage would likely afford. Management believes that many
of its competitors operate without such coverage.
 
14. SUBSEQUENT EVENTS
 
     In September 1993, TSI announced a $5,000,000 disposal of operations charge
taken in the fourth quarter of fiscal 1993 to reduce the net assets of its
German preclinical testing and regulatory consulting subsidiary, IBR Forschungs
GmbH to net realizable value. The recent loss of significant sales to one
customer, lower demand for IBR's services and the current high costs of doing
business in Germany contributed to a

situation in which IBR could not expect to operate profitably without a major
financial commitment, which TSI chose not to make. During the second quarter of
fiscal 1994, operations at IBR ceased and it entered into liquidation
proceedings.
 
     On October 8, 1993, the bank provided TSI with a commitment to extend the
revolving line of credit until August 1, 1994. Under the terms of the extension,
TSI continued to have a $1,000,000 standby letter of credit and could borrow up
to 70% of the amount of the eligible accounts receivable of its U.S.
subsidiaries, subject to a maximum borrowing of $2,000,000. In consideration for
the extension, TSI agreed to pay a fee of $1,000,000, payable at the rate of
$10,000 per month from October 1993 to April 1994, with the balance due in
August 1994 or upon an earlier refinancing. In addition, the company issued
20,000 shares of TSI's common stock and a warrant to purchase an additional
188,000 shares of common stock to the bank, which becomes exercisable at $0.01
per share in quarterly increments until July 1994 if the line of credit and
TSI's equipment lease line remain outstanding. Warrants to purchase 40,000
shares are currently exercisable with the remainder to become exercisable in
July 1994. The bank line continues to be secured by the capital stock of the
U.S. subsidiaries and GDRU.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 67 of chapter 156B of the Massachusetts Business Corporation Law
grants the Company the power to indemnify any director, officer, employee or
agent to whatever extent permitted by the Company's Restated Articles of
Organization, Bylaws or a vote adopted by the holders of a majority of the
shares entitled to vote thereon, unless such indemnitee has been adjudicated in
any proceeding not to have acted in good faith in the reasonable belief that his
or her actions were in the best interests of the corporation or, to the extent
that the matter for which indemnification is sought relates to service with
respect to an employee benefit plan, in the best interests of the participants
or beneficiaries of such employee benefit plan. Such indemnification may include
payment by the Company of expenses incurred in defending a civil or criminal
action or proceeding in advance of the final disposition of such action or
proceeding, upon receipt of an undertaking by the person indemnified to repay
such payment if he or she shall be adjudicated to be not entitled to
indemnification under the statute.

      Article VI of the Company's Bylaws provides that the Company shall, to the
extent legally permissible, indemnify each person who may serve or who has
served at any time as a director or officer of the corporation or of any of its
subsidiaries, or who, at the request of the Company, may serve or at any time
has served as a director, officer or trustee of, or in a similar capacity with,
another organization or an employee benefit plan, against all expenses and
liabilities (including counsel fees, judgments, fines, excise taxes, penalties
and amounts payable in settlements) reasonably incurred by or imposed upon such
person in connection with any threatened, pending or completed action, suit or
other proceeding, whether civil, criminal, administrative or investigative, in
which he or she may become involved by reason of his or her serving or having
served in such capacity (other than a proceeding voluntarily initiated by such
person unless he or she is successful on the merits, the proceeding was
authorized by the corporation or the proceeding seeks a declaratory judgment
regarding his or her own conduct). Such indemnification shall include payment by
the Company of expenses incurred in defending a civil or criminal action or
proceeding in advance of the final disposition of such action or proceeding,
upon receipt of an undertaking by the person indemnified to repay such payment
if he or she shall be adjudicated to be not entitled to indemnification under
Article VI, which undertaking may be accepted without regard to the financial
ability of such person to make repayment.

      The indemnification provided for in Article VI is a contract right inuring
to the benefit of the directors, officers and others entitled to
indemnification. In addition, the indemnification is expressly not exclusive of
any other rights to which such director, officer or other person may be entitled
by contract or otherwise under law, and inures to the benefit of the heirs,
executors and administrators of such a person.

      The Company also has in place agreements with certain officers and
directors which affirm the Registrant's obligation to indemnify them to the
fullest extent permitted by law and contain various procedural and other
provisions which expand

                                      II-1

<PAGE>   111



the protection afforded by the Company's Bylaws.

      Section 13(b)(1 1/2) of chapter 156B of the Massachusetts Business
Corporation Law provides that a corporation may, in its Articles of
Organization, eliminate the directors' personal liability to the corporation and
its stockholders for monetary damages for breaches of fiduciary duty, except in
circumstances involving (i) a breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
unauthorized distributions and loans to insiders, and (iv) transactions from
which the director derived an improper personal benefit. Section 6.5 of the
Registrant's Restated Articles of Organization provides that no director shall
be personally liable to the corporation or its stockholders for monetary damages
for any breach of fiduciary duty as a director, except to the extent that such
exculpation is not permitted under the Massachusetts Business Corporation Law as
in effect when such liability is determined.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

      Since June 1, 1993, the Company has issued and sold the following
securities, in each case in reliance on an exemption from required registration
pursuant to Section 4(2) of the Securities Act.

      Upon its acquisition of TSI, GTC assumed an outstanding warrant that TSI
had issued to a commercial bank. Based on the acquisition conversion ratio, such
warrant currently covers 37,600 shares of GTC Common Stock at exercise price of
$0.05 per share.

      In September 1994, TSI issued a Common Stock Purchase warrant covering
20,000 shares of its common stock to FSI, a commercial equipment leasing
company. Upon the acquisition of TSI by GTC in October 1994, GTC assumed such
warrant, which currently covers 4,000 shares of GTC Common Stock. Subsequently,
in June 1995 and March 1996, GTC issued additional warrants to FSI, each
covering 2,000 shares of Common Stock, in consideration of addition lease
financing. In each such case, the warrant exercise price was based on the then
current market value of the underlying securities as reported by Nasdaq.

      In February 1995, GTC exercised its rights under a Common Stock Put
Agreement with Genzyme, selling 500,000 shares of Common Stock to Genzyme at a
fixed price of $8.00 per share.

      In June 1995, the Company issued and sold 1,333,333 shares of Common Stock
to Genzyme in exchange for the retirement of $3,999,999 in debt owed by the
Company to Genzyme. Such debt-to-equity conversion at $3.00 per share was based
on the closing price of the Common Stock on June 7, 1995, as reported by the
National Market System of Nasdaq.

      In July 1995, the Company acquired all of the outstanding capital stock of
BioDevelopment Laboratories, Inc. in exchange for shares of GTC Common Stock. In
connection with the acquisition, the Company and Genzyme entered into a
Securities Exchange Agreement, pursuant to which the former BDL stockholders
exchanged 475,467 of the 1,207,233 shares of Common Stock issued by the Company
for 33,945 shares of Genzyme General Division Stock. While the remainder of the
shares of Common Stock issued by the Company have been registered under the
Securities Act subsequent to the transaction, the shares acquired by Genzyme
have not been registered. The exchange ratio was based on the relative market
prices of the GTC Common Stock and the Genzyme General Division stock.

      In July 1995, the Company obtained a credit line with a commercial bank
secured, in part, by Genzyme's guaranty of the Company's obligations thereunder.
In exchange for such guaranty, the Company issued a Common Stock Purchase
Warrant to Genzyme covering 145,000 shares of Common Stock at an exercise price
of $2.84375, the market price at the date of the Agreement as reported by
Nasdaq.

      On March 31, 1996, the Company had exercised its option to convert an
aggregate of $ 150,000 of its debt to Genzyme under the Convertible Debt
Agreement in exchange for an aggregate of 26,244 shares of GTC Common Stock.

therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

      (b)  The undersigned Registrant hereby undertakes that:

         (1)   For purposes of determining any liability under the Securities
               Act, the information omitted from the form of prospectus filed as
               part of this Registration Statement in reliance upon Rule 430A
               and contained in a form of prospectus filed by the Registrant
               pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
               Act shall be deemed to be part of this Registration Statement as
               of the time it was declared effective.

         (2)   For the purpose of determining any liability under the Securities
               Act, each post-effective amendment that contains a form of
               prospectus shall be deemed to be a new registration statement
               relating to the securities offered therein, and the offering of
               such securities at that time shall be deemed to be the initial
               bona fide offering thereof.

PAINEWEBBER INCORPORATED
HAMBRECHT & QUIST LLC
NEEDHAM & COMPANY, INC.
  As Representatives of the
  several Underwriters
c/o PaineWebber Incorporated
  1285 Avenue of the Americas
  New York, New York  10019

Dear Sirs:

         Genzyme Transgenics Corporation, a Massachusetts corporation (the
"Company"), proposes to sell an aggregate of 3,000,000 shares (the "Firm
Shares") of the Company's Common Stock, $.01 par value per share (the "Common
Stock"), to you and to the several other Underwriters named in Schedule I hereto
(collectively, the "Underwriters"), for whom you are acting as representatives
(the "Representatives"). The Company has also agreed to grant to you and the
other Underwriters an option (the "Option") to purchase up to an additional
450,000 shares of Common Stock (the "Option Shares"), on the terms and for the
purposes set forth in Section l(b). The Firm Shares and the Option Shares are
referred to collectively herein as the "Shares".

         The initial public offering price per share for the Shares and the
purchase price per share for the Shares to be paid by the several Underwriters
shall be agreed upon by the Company and the Representatives, acting on behalf of
the several Underwriters, and such agreement shall be set forth in a separate
written instrument substantially in the form of Exhibit A hereto (the "Price
Determination Agreement"). The Price Determination Agreement may take the form
of an exchange of any standard form of written telecommunication between the
Company and the Representatives and shall specify such applicable information as
is indicated in Exhibit A hereto. The offering of the Shares will be governed by
this Agreement,
<PAGE>   2
as supplemented by the Price Determination Agreement. From and after the date of
the execution and delivery of the Price Determination Agreement, this Agreement
shall be deemed to incorporate, and, unless the context otherwise indicates, all
references contained herein to "this Agreement" and to the phrase "herein" shall
be deemed to include, the Price Determination Agreement.

         The Company confirms as follows its agreement with the Representatives
and the several other Underwriters.

         1.       Agreement to Sell and Purchase.

                  (a) On the basis of the representations, warranties and
agreements of the Company herein contained and subject to all the terms and
conditions of this Agreement, (i) the Company agrees to sell to the several
Underwriters and (ii) each of the Underwriters, severally and not jointly,
agrees to purchase from the Company, at the purchase price per share for the
Firm Shares to be agreed upon by the Representatives and the Company in
accordance with Section 1(c) hereof and set forth in the Price Determination
Agreement, the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I, plus such additional number of Firm Shares which such
Underwriter may become obligated to purchase pursuant to Section 8 hereof.
Schedule I may be attached to the Price Determination Agreement.

                  (b) Subject to all the terms and conditions of this Agreement,
the Company grants the Option to the several Underwriters to purchase, severally
and not jointly, up to 450,000 Option Shares from the Company at the same price
per share as the Underwriters shall pay for the Firm Shares. The Option may be
exercised only to cover over-allotments in the sale of the Firm Shares by the
Underwriters and may be exercised in whole or in part at any time (but not more
than once) on or before the 45th day after the date of the Price Determination
Agreement, upon written or telegraphic notice (the "Option Shares Notice") by
the Representatives to the Company no later than 12:00 noon, New York City time,
at least two and no more than five business days before the date specified for
closing in the Option Shares Notice (the "Option Closing Date") setting forth
the aggregate number of Option Shares to be purchased and the time and date for
such purchase. On the Option Closing Date, the Company will issue and sell to
the Underwriters the number of Option Shares set forth in the Option Shares
Notice, and each Underwriter will purchase such percentage of the Option Shares
as is equal to the percentage of Firm Shares that such Underwriter is
purchasing, as adjusted by the Representatives in such manner as they deem
advisable to avoid fractional shares.

                  (c) The initial public offering price per share for the Firm
Shares and the purchase price per share for the Firm Shares to be paid by the
several Underwriters shall be agreed upon and set forth in the Price
Determination Agreement. In the event that such price has not been agreed upon
and the Price Determination Agreement has not been executed by the close of
business on the fourteenth business day following the date on which the
Registration


                                      - 2 -
<PAGE>   3
Statement becomes effective, this Agreement shall terminate forthwith, without
liability of any party to any other party except that Section 6 shall remain in
effect.

         2. Delivery and Payment. Delivery of certificates evidencing the Firm
Shares shall be made to the Representatives for the accounts of the Underwriters
against payment of the purchase price [by certified or official bank check
payable to the order of the Company] [by wire transfer to an account designated
by the Company in Federal (same-day) funds] at the office of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019. Such
payment shall be made at 10:00 a.m., New York City time, on the [third][fourth]
business day after the date on which the first bona fide offering of the Shares
to the public is made by the Underwriters or at such time on such other date,
not later than ten business days after such date as may be agreed upon by the
Company and the Representatives (such date is hereinafter referred to as the
"Closing Date").

         To the extent the Option is exercised, delivery of the Option Shares
against payment by the Underwriters (in the manner specified above) will take
place at the office specified above for the Closing Date at the time and date
(which may be the Closing Date) specified in the Option Shares Notice.

         Certificates evidencing the Shares shall be in definitive form and
shall be registered in such names and in such denominations as the
Representatives shall request at least two business days prior to the Closing

Option Closing Date, as the case may be.

         The cost of original issue tax stamps, if any, in connection with the

         3.       Representations and Warranties of the Company.  The
Company represents, warrants and covenants to each Underwriter
that:

                  (a) A registration statement (Registration No. 333-_____) on
Form S-1 relating to the Shares, including a preliminary prospectus and such
amendments to such registration statement as may have been required to the date
of this Agreement, has been prepared by the Company under the provisions of the
Securities Act of 1933, as amended (the "Act"), and the rules and regulations
(collectively referred to as the "Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") thereunder, and has been filed with the
Commission. The registration statement contains a form of preliminary


                                      - 3 -
<PAGE>   4
prospectus to be used in connection with the offering and sale of the Shares
(the "Preliminary Prospectus"). The term "preliminary prospectus" as used herein
means a preliminary prospectus as contemplated by Rule 430 or Rule 430A ("Rule
430A") of the Rules and Regulations included at any time as part of the
registration statement. Copies of such registration statement and amendments
have been delivered to the Representatives and copies of each related
Preliminary Prospectus have been delivered to the Representatives. The term
"Registration Statement" means the registration statement as amended at the time
it becomes or became effective (the "Effective Date"), including financial
statements and all exhibits and any information deemed to be included by Rule
430A or Rule 434 of the Rules and Regulations. If the Company files a
registration statement to register a portion of the Shares and relies on Rule
462(b) of the Rules and Regulations for such registration statement to become
effective upon filing with the Commission (the "Rule 462 Registration
Statement"), then any reference to the "Registration Statement" shall be deemed
to include the Rule 462 Registration Statement, as amended from time to time.
The term "Prospectus" means a prospectus relating to the Shares (the
"Prospectus") in the form it is first filed with the Commission pursuant to Rule
424(b) of the Rules and Regulations or, if no such filing is required, the form
of final prospectus included in the Registration Statement at the Effective
Date.

                  (b) On the Effective Date, the date the Prospectus is first
filed with the Commission pursuant to Rule 424(b) (if required), at all times
subsequent to and including the Closing Date and, if later, the Option Closing
Date and when any post-effective amendment to the Registration Statement becomes
effective or any amendment or supplement to the Prospectus is filed with the
Commission, the Registration Statement and the Prospectus (as amended or as
supplemented if the Company shall have filed with the Commission any amendment
or supplement thereto), including the financial statements included in the
Prospectus, did or will comply with all applicable provisions of the Act and the
Rules and Regulations and will contain all statements required to be stated
therein in accordance with the Act and the Rules and Regulations. On the
Effective Date and when any post-effective amendment to the Registration
Statement becomes effective, no part of the Registration Statement or any such
amendment did or will contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein not misleading. At the Effective Date, the date the
Prospectus or any amendment or supplement to the Prospectus is filed with the
Commission and at the Closing Date and, if later, the Option Closing Date, the
Prospectus did not or will not contain any untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. The
foregoing representations and warranties in this Section 3(b) do not apply to
any statements or omissions made in reliance on and in conformity with
information relating to any Underwriter furnished in writing to the Company by
the Representatives specifically for inclusion in the Registration Statement or
Prospectus or any amendment or supplement thereto. For all purposes of this
Agreement, the Company acknowledges that ___________ set forth in the Prospectus
constitutes the only information relating to any Underwriter furnished in
writing to the Company by the Representatives specifically for inclusion in the
Preliminary Prospectus, the Registration Statement or the Prospectus. The
Company has not distributed any offering material in connection with the
offering or sale of the Shares other than the


                                      - 4 -

Registration Statement, the preliminary prospectus, the Prospectus or any other
materials, if any, permitted by the Act.

                  (c) The only subsidiaries (as defined in the Rules and
Regulations) of the Company are the subsidiaries listed on Exhibit 21 to the
Registration Statement (the "Subsidiaries"). Each of the Company and each of its
Subsidiaries is, and at the Closing Date will be, a corporation duly organized,
validly existing and in good standing under the laws of its jurisdiction of
incorporation. Each of the Company and each of its Subsidiaries has, and at the
Closing Date will have, full power and authority to conduct all the activities
conducted by it, to own or lease all the assets owned or leased by it and to
conduct its business as described in the Registration Statement and the
Prospectus. Each of the Company and each of its Subsidiaries is, and at the
Closing Date will be, duly licensed or qualified to do business and in good
standing as a foreign corporation in all jurisdictions in which the nature of
the activities conducted by it or the character of the assets owned or leased by
it makes such licensing or qualification necessary, except where the failure to
be so licensed or qualified would not have a material adverse effect on the
business, properties, business prospects, condition (financial or otherwise), or
results of operations of the Company and its Subsidiaries, taken as a whole
(collectively, the "Business of the Company"). All of the outstanding shares of
capital stock of the Subsidiaries have been duly authorized and validly issued
and are fully paid and nonassessable and are owned by the Company free and clear
of all liens, encumbrances and claims whatsoever. Except for the stock of the
Subsidiaries and as disclosed in the Registration Statement, the Company does
not own, and at the Closing Date will not own, directly or indirectly, any
shares of stock or any other equity or long-term debt securities of any
corporation or have any equity interest in any firm, partnership, joint venture,
association or other entity. Complete and correct copies of the articles of
organization and the by-laws of the Company and each of its Subsidiaries and all
amendments thereto have been delivered to the Representatives, and no changes
therein will be made subsequent to the date hereof and prior to the Closing Date
or, if later, the Option Closing Date.

                  (d) The outstanding shares of Common Stock have been, and the
Shares to be issued and sold by the Company upon such issuance will be, duly
authorized, validly issued, fully paid and nonassessable and will not be subject
to any preemptive or similar right, and none of such shares will be subject to
any pledge, lien, security interest, charge, claim, equity or encumbrance of any
kind. The description of the capital stock of the Company in the Registration
Statement and the Prospectus is, and at the Closing Date will be, complete and
accurate in all material respects. Except as set forth in the Prospectus, the
Company does not have outstanding, and at the Closing Date will not have
outstanding, any options to purchase, or any rights or warrants to subscribe
for, or any securities or obligations convertible into, or any contracts or
commitments to issue or sell, any shares of Common Stock, any shares of capital
stock of any Subsidiary or any such warrants, convertible securities or
obligations (except options, rights or shares issued after the date as of which
information with respect thereto is given in the Prospectus pursuant to employee
benefits plans [described in the Prospectus]).

& Lybrand L.L.P.) and TSI Corporation and the Company (in the case of Ernst &
Young L.L.P.) as required by the Act and the Rules and Regulations. The
statements included in the Registration Statement with respect to the
Accountants pursuant to Rule 509 of Regulation S-K of the Rules and Regulations
are true and correct in all material respects.

controls sufficient to provide reasonable assurance that (i) transactions are

material change in the capitalization of the Company or in the Business of the
Company arising for any reason whatsoever, (ii) neither the Company nor any of

obligations, direct or contingent, nor has it entered into nor will it enter
into any material transactions other than pursuant to this Agreement and the
transactions referred to herein and (iii) the Company has not and will not have
paid or declared any dividends or other distributions of any kind on any class
of its capital stock.

                  (h) The Company is not an "investment company" or an
"affiliated person" of, or "promoter" or "principal underwriter" for, an
"investment company," as such terms are defined in the Investment Company Act of
1940, as amended.

party or by which its property is bound or affected, excluding from the
foregoing clauses (i), (ii) and (iii) those licenses, permits, consents, orders
and approvals the absence of which, and those violations, failures to perform
and defaults which, in the aggregate, would not have a material adverse effect
on the Business of the Company. To the best knowledge of the Company, no other
party under any contract or other agreement to which it is a party is in default
in any respect thereunder, except for defaults that would not have a material
adverse effect on the Business of the Company. Neither the Company nor any of
its Subsidiaries is, nor at the Closing Date will be, in violation of any
provision of its articles of organization or by-laws.

default under, or give any other party a right to terminate any of its
obligations under, or result in the acceleration of any obligation under, the
articles of organization or by-laws of the Company or any of its Subsidiaries,

is a party or by which the

Subsidiary, constitute valid and binding agreements of the Company or such
Subsidiary and are enforceable against the Company or such Subsidiary in
accordance with the terms thereof.

the Prospectus to comply with law, the Company will forthwith prepare and duly
file with the Commission an appropriate supplement or amendment thereto, and

obligations hereunder, the Company will reimburse the several Underwriters for
all out-of-pocket expenses (including the fees, disbursements and other charges
of counsel for the Underwriters) reasonably incurred by them in connection
herewith.

                  (k) The Company will not at any time, directly or indirectly,
take any action intended, or which might reasonably be expected, to cause or

the Company's executive officers and directors and employees previously
identified to the Company by the Representatives to enter into agreements with
the Representatives in the form set forth in Exhibit B to the effect that they
will not, for a period of [365] days after the commencement of the public

Representatives, offer to sell, sell, contract to sell, grant any option to sell
or otherwise dispose of or require the Company to file with the Commission a
registration statement under the Act to register any shares of Common Stock, or
securities convertible or exchangeable for shares of Common Stock or warrants or
other rights to acquire such shares (other than by the Company pursuant to
employee stock option plans or in connection with other employee incentive
compensation arrangements).

         5.       Conditions of the Obligations of the Underwriters. In addition
to the execution and delivery of the Price Determination Agreement, the
obligations of each Underwriter hereunder are subject to the following
conditions:

                  (a) Notification that the Registration Statement has become
effective shall be received by the Representatives not later than 3:00 p.m., New
York City time, on the date of this Agreement or at such later date and time as
shall be consented to in writing by the Representatives, and all filings
required by Rule 424 of the Rules and Regulations and Rule 430A shall have been
made.

                  (b) (i) No stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for that
purpose shall be pending or threatened by the Commission, (ii) no order
suspending the effectiveness of the Registration Statement or the qualification
or registration of the Shares under the securities or Blue Sky laws of any
jurisdiction shall be in effect and no proceeding for such purpose shall be
pending before or threatened or contemplated by the Commission or the
authorities of any such jurisdiction, (iii) any request for additional
information on the part of the staff of the Commission or any such authorities
shall have been complied with to the satisfaction of the staff of the Commission
or such authorities and (iv) after the date hereof no amendment or supplement to
the Registration Statement or the Prospectus shall have been filed unless a copy
thereof was first submitted to the Representatives and the Representatives do
not object thereto in good faith, and the Representatives shall have received
certificates, dated the Closing Date and the Option Closing Date and signed by
the Chief Executive Officer or the Chairman of the Board of Directors of the
Company and the Chief Financial Officer of the Company (who may, as to
proceedings threatened, rely upon the best of their information and belief), to
the effect of clauses (i), (ii) and (iii).

                  (c) Since the respective dates as of which information is
given in the Registration Statement and the Prospectus, (i) there shall not have

Prospectus and (ii) neither the Company nor any of its Subsidiaries shall have
sustained any material loss or interference with its business or properties from
fire, explosion, flood or other casualty, whether or not covered by insurance,
or from any labor dispute or any court or legislative or other governmental
action, order or decree, which is not set forth in the Registration Statement
and the Prospectus, if in the judgment of the Representatives, any such
development makes it impracticable or inadvisable to consummate the sale and
delivery of the Shares by the Underwriters at the initial public offering price.

                  (d) Since the respective dates as of which information is
given in the Registration Statement and the Prospectus, there shall have been no
litigation or other proceeding instituted against the Company, any of its
Subsidiaries, or any of their respective officers or directors in their
capacities as such, before or by any Federal, state or local court, commission,
regulatory body, administrative agency or other governmental body, domestic or

                                                     
                                     - 13 -
<PAGE>   14
foreign, in which litigation or proceeding an unfavorable ruling, decision or
finding would materially and adversely affect the Business of the Company.

                  (e) Each of the representations and warranties of the Company
contained herein shall be true and correct in all material respects at the
Closing Date, as if made at the Closing Date, and, with respect to the Option
Shares, at the Option Closing Date, as if made at the Option Closing Date, and
all covenants and agreements contained herein to be performed on the part of the
Company and all conditions contained herein to be fulfilled or complied with by
the Company at or prior to the Closing Date and, with respect to the Option

the Closing Date and, with respect to the Option Shares, the Option Closing
Date, and satisfactory in form and substance to counsel for the Underwriters,
(i) from Palmer & Dodge, counsel for the Company, to the effect set forth in
Exhibit C, and (ii) from Mark A. Hofer, patent and regulatory counsel for the
Company, to the effect set forth in Exhibit D.

                  (g) The Representatives shall have received an opinion, dated

                  (h) On the date of the Prospectus, each of the Accountants
shall have furnished to the Representatives a letter, dated the date of its
delivery, addressed to the Representatives and in form and substance
satisfactory to the Representatives, confirming, in the case of Coopers &
Lybrand, L.L.P., that they are independent accountants with respect to the
Company and in the case of Ernst & Young L.L.P., that they are independent
accountants with respect to TSI Corporation and the Company, as required by the
Act and the Rules and Regulations and with respect to the financial and other
statistical and numerical information contained in the Registration Statement.
At the Closing Date and, as to the Option Shares, the Option Closing Date, each
of the Accountants shall have furnished to the Representatives a letter, dated
the date of its delivery, which shall confirm, on the basis of a review in
accordance with the procedures set forth in the letters from the Accountants,
that nothing has come to their attention during the period from the date of the
letter referred to in the prior sentence to a date (specified in the letter) not
more than five days prior to the Closing Date and the Option Closing Date, as
the case may be, which would require any change in their letter dated the date
hereof if it were required to be dated and delivered at the Closing Date and the
Option Closing Date.

                  (i) At the Closing Date and, as to the Option Shares, the

                                     - 14 -
<PAGE>   15
                           (i) Each signer of such certificate has carefully
                  examined the Registration Statement and the Prospectus and (A)
                  as of the date of such certificate, such documents are true
                  and correct in all material respects and do not omit to state
                  a material fact required to be stated therein or necessary in
                  order to make the statements therein, in light of the
                  circumstances under which they were made, not misleading and
                  (B) since the Effective Date, no event has occurred as a
                  result of which it is necessary to amend or supplement the
                  Prospectus in order to make the statements therein not untrue
                  or misleading in any material respect.

                           (ii) Each of the representations and warranties of
                  the Company contained in this Agreement were, when originally
                  made, and are, at the time such certificate is delivered, true
                  and correct in all material respects.

                           (iii) Each of the covenants required to be performed
                  by the Company herein on or prior to the date of such
                  certificate has been duly, timely and fully performed and each
                  condition herein required to be complied with by the Company
                  on or prior to the delivery of such certificate has been duly,
                  timely and fully satisfied or fulfilled.

                  (j) On or prior to the Closing Date, the Representatives shall
have received the executed agreements referred to in Section 4(n).

                  (k) The Shares shall be qualified for sale in such
jurisdictions as the Representatives may reasonably request, and each such
qualification shall be in effect and not subject to any stop order or other
proceeding on the Closing Date and the Option Closing Date.

                  (l) Prior to 3:00 P.M. on the date hereof, the Shares shall
have been duly qualified for quotation on the NASDAQ/NMS.

                  (m) The Company shall have furnished to the Representatives
such certificates, in addition to those specifically mentioned herein, as the
Representatives may have reasonably requested as to the accuracy and
completeness at the Closing Date and the Option Closing Date of any statement in
the Registration Statement or the Prospectus, as to the accuracy at the Closing
Date and the Option Closing Date of the representations and warranties of the
Company herein, as to the performance by the Company of its obligations
hereunder, or as to the fulfillment of the conditions concurrent and precedent
to the obligations hereunder of the Representatives.

                  (n) At the Closing Date and, as to the Option Shares, the
Option Closing Date, there shall be furnished to the Representatives an accurate
certificate of Genzyme, dated the date of its delivery, signed by each of the
Chief Executive Officer and the Chief Financial Officer of Genzyme, in form and
substance satisfactory to the Representatives, to the effect that:


                                     - 15 -
<PAGE>   16
                           (i) Each of the representations and warranties of the
                  Company contained in this Agreement were, when originally
                  made, and are, at the time such certificate is delivered, true
                  and correct in all material respects.

                           (ii) Each of the covenants required to be performed
                  by the Company herein on or prior to the date of such
                  certificate has been duly, timely and fully performed and each
                  condition herein required to be complied with by the Company
                  on or prior to the delivery of such certificate has been duly,
                  timely and fully satisfied or fulfilled.

                  (o) Concurrently with the execution and delivery of this
Agreement, there shall be furnished to the Representatives a letter agreement
from Genzyme to the effect that Genzyme shall have the joint and several
obligation, with the Company, to (A) pay, or reimburse if paid by the
Representatives, all costs and expenses set forth in Section 4(i) of this
Agreement and (B) under the circumstances set forth in Section 4(j), reimburse
the several Underwriters for all out-of-pocket expenses referred to in such
section.

         6.       Indemnification.

                  (a) The Company will indemnify and hold harmless each
Underwriter and each person, if any, who controls each Underwriter (and each
director, officer, employee and agent of each Underwriter alleged to control any
Underwriter) within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, from and against any and all losses, claims, liabilities, expenses
and damages (including any and all investigative, legal and other expenses
reasonably incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding or any claim asserted), to which they, or any of
them, may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, liabilities, expenses or damages arise out of or are based on
any untrue statement or alleged untrue statement of a material fact contained in
any preliminary prospectus, the Registration Statement or the Prospectus or any
amendment or supplement to the Registration Statement or the Prospectus, or the
omission or alleged omission to state in such document a material fact required
to be stated in it or necessary to make the statements in it not misleading,
provided that the Company will not be liable to the extent that such loss,
claim, liability, expense or damage arises from the sale of the Shares in the
public offering to any person by a Underwriter and is based on an untrue
statement or omission or alleged untrue statement or omission made in reliance
on and in conformity with information relating to any Underwriter furnished in
writing to the Company by the Representatives on behalf of any Underwriter
expressly for inclusion in the Registration Statement, the Preliminary
Prospectus or the Prospectus; and provided, further, that the Company shall not
be liable to any Underwriter (or person controlling such Underwriter) under this
subsection (a) with respect to the Preliminary Prospectus to the extent that any
loss, claim, liability, expense or damage of such Underwriter results from the
fact that such Underwriter sold Shares to a person to whom there was not given
or sent, at or prior to the written confirmation of such sale, a copy of the
Prospectus or of the Prospectus as then amended or supplemented in any case
where such delivery is required by the Act if the Company had previously
furnished copies thereof to such Underwriter and the loss, claim,


                                     - 16 -
<PAGE>   17
liability, expense or damage of such Underwriter results from an untrue
statement or omission of a material fact contained in the Preliminary Prospectus
which was corrected in the Prospectus (or the Prospectus as amended or
supplemented). This indemnity agreement will be in addition to any liability
that the Company might otherwise have.

                  (b) Each Underwriter will indemnify and hold harmless the
Company, each person, if any, who controls the Company (and each officer,
director, employee or agent of the Company alleged to control the Company)
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
each director of the Company and each officer of the Company who signs the
Registration Statement to the same extent as the foregoing indemnity from the
Company to each Underwriter, but only insofar as losses, claims, liabilities,
expenses or damages arise out of or are based on any untrue statement or
omission or alleged untrue statement or omission made in reliance on and in
conformity with information relating to any Underwriter furnished in writing to
the Company by the Representatives on behalf of such Underwriter expressly for
use in the Registration Statement, the Preliminary Prospectus or the Prospectus.
This indemnity will be in addition to any liability that each Underwriter might
otherwise have.

                  (c) Any party that proposes to assert the right to be
indemnified under this Section 6 will, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim is to
be made against an indemnifying party or parties under this Section 6, notify
each such indemnifying party of the commencement of such action, enclosing a
copy of all papers served, but the omission so to notify such indemnifying party
will not relieve it from any liability that it may have to any indemnified party
under the foregoing provisions of this Section 6 unless, and only to the extent
that, such omission results in the forfeiture of substantive rights or defenses
by the indemnifying party. If any such action is brought against any indemnified
party and it notifies the indemnifying party of its commencement, the
indemnifying party will be entitled to participate in and, to the extent that it
elects by delivering written notice to the indemnified party promptly after
receiving notice of the commencement of the action from the indemnified party,
jointly with any other indemnifying party similarly notified, to assume the
defense of the action, with counsel satisfactory to the indemnified party, and
after notice from the indemnifying party to the indemnified party of its
election to assume the defense, the indemnifying party will not be liable to the
indemnified party for any legal or other expenses except as provided below and
except for the reasonable costs of investigation subsequently incurred by the
indemnified party in connection with the defense. The indemnified party will
have the right to employ its own counsel in any such action, but the fees,
expenses and other charges of such counsel will be at the expense of such
indemnified party unless (i) the employment of counsel by the indemnified party
has been authorized in writing by the indemnifying party, (ii) the indemnified
party has reasonably concluded (based on advice of counsel) that there may be
legal defenses available to it or other indemnified parties that are different
from or in addition to those available to the indemnifying party, (iii) a
conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (iv) the indemnifying
party has not in fact employed


                                     - 17 -
<PAGE>   18
counsel to assume the defense of such action within a reasonable time after
receiving notice of the commencement of the action, in each of which cases the
reasonable fees, disbursements and other charges of counsel will be at the
expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm admitted to
practice in such jurisdiction at any one time for all such indemnified party or
parties. All such fees, disbursements and other charges will be reimbursed by
the indemnifying party promptly as they are incurred. An indemnifying party will
not be liable for any settlement of any action or claim effected without its
written consent (which consent will not be unreasonably withheld).

                  (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing
paragraphs of this Section 6 is applicable in accordance with its terms but for
any reason is held to be unavailable from the Company or the Underwriters, the
Company and the Underwriters will contribute to the total losses, claims,
liabilities, expenses and damages (including any investigative, legal and other
expenses reasonably incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claim asserted, but after
deducting any contribution received by the Company from persons other than the
Underwriters, such as persons who control the Company within the meaning of the
Act, officers of the Company who signed the Registration Statement and directors
of the Company, who also may be liable for contribution) to which the Company
and any one or more of the Underwriters may be subject in such proportion as
shall be appropriate to reflect the relative benefits received by the Company,
on the one hand, and the Underwriters, on the other. The relative benefits
received by the Company, on the one hand, and the Underwriters, on the other,
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus. If, but only
if, the allocation provided by the foregoing sentence is not permitted by
applicable law, the allocation of contribution shall be made in such proportion
as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the Company, on the one hand,
and the Underwriters, on the other, with respect to the statements or omissions
which resulted in such loss, claim, liability, expense or damage, or action in
respect thereof, as well as any other relevant equitable considerations with
respect to such offering. Such relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact relates to information supplied by
the Company or the Representatives on behalf of the Underwriters, the intent of
the parties and their relative knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company and the
Underwriters agree that it would not be just and equitable if contributions
pursuant to this Section 6(d) were to be determined by pro rata allocation (even
if the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, liability, expense or damage, or action in
respect thereof, referred to above in this Section 6(d) shall be deemed to
include, for purposes of this Section 6(d), any


                                     - 18 -
<PAGE>   19
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6(d), no Underwriter shall be
required to contribute any amount in excess of the underwriting discounts
received by it, and no person found guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) will be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute as provided in
this Section 6(d) are several in proportion to their respective underwriting
obligations and not joint. For purposes of this Section 6(d), any person who
controls a party to this Agreement within the meaning of the Act will have the
same rights to contribution as that party, and each officer of the Company who
signed the Registration Statement will have the same rights to contribution as
the Company, subject in each case to the provisions hereof. Any party entitled
to contribution, promptly after receipt of notice of commencement of any action
against such party in respect of which a claim for contribution may be made
under this Section 6(d), will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 6(d). No party will be liable for
contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).

                  (e) The indemnity and contribution agreements contained in
this Section 6 and the representations and warranties of the Company contained
in this Agreement shall remain operative and in full force and effect regardless
of (i) any investigation made by or on behalf of the Underwriters, (ii)
acceptance of any of the Shares and payment therefor or (iii) any termination of
this Agreement.

         7.       Termination. The obligations of the several Underwriters under
this Agreement may be terminated at any time on or prior to the Closing Date
(or, with respect to the Option Shares, on or prior to the Option Closing Date),
by notice to the Company from the Representatives, without liability on the part
of any Underwriter to the Company, if, prior to delivery of and payment for the
Firm Shares (or the Option Shares, as the case may be), in the sole judgment of
the Representatives, (i) trading in any of the equity securities of the Company
shall have been suspended by the Commission or by the NASDAQ/NMS, (ii) trading
in securities generally on the New York Stock Exchange shall have been suspended
or limited or minimum or maximum prices shall have been generally established on
such exchange, or additional material governmental restrictions, not in force on
the date of this Agreement, shall have been imposed upon trading in securities
generally by such exchange or by order of the Commission or any court or other
governmental authority, (iii) a general banking moratorium shall have been
declared by either Federal or New York State authorities or (iv) any material
adverse change in the financial or securities markets in the United States or in
political, financial or economic conditions in the United States or any outbreak
or material escalation of hostilities or declaration by the United States of a
national emergency or war or other calamity or crisis shall have occurred, the
effect of any of which is such as to make it, in the sole judgment of the
Representatives, impracticable or inadvisable to market the Shares on the terms
and in the manner contemplated by the Prospectus.


                                     - 19 -
<PAGE>   20
         8.       Substitution of Underwriters. If any one or more of the
Underwriters shall fail or refuse to purchase any of the Firm Shares which it or
they have agreed to purchase hereunder, and the aggregate number of Firm Shares
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase is not more than one-tenth of the aggregate number of Firm Shares,
the other Underwriters shall be obligated, severally, to purchase the Firm
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase, in the proportions which the number of Firm Shares which
they have respectively agreed to purchase pursuant to Section 1 bears to the
aggregate number of Firm Shares which all such non-defaulting Underwriters have
so agreed to purchase, or in such other proportions as the Representatives may
specify; provided that in no event shall the maximum number of Firm Shares which
any Underwriter has become obligated to purchase pursuant to Section 1 be
increased pursuant to this Section 8 by more than one-ninth of the number of
Firm Shares agreed to be purchased by such Underwriter without the prior written
consent of such Underwriter. If any Underwriter or Underwriters shall fail or
refuse to purchase any Firm Shares and the aggregate number of Firm Shares which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase exceeds one-tenth of the aggregate number of the Firm Shares and
arrangements satisfactory to the Representatives and the Company for the
purchase of such Firm Shares are not made within 48 hours after such default,
this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Company for the purchase or sale of any Shares
under this Agreement. In any such case either the Representatives or the Company
shall have the right to postpone the Closing Date, but in no event for longer
than seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. Any action taken pursuant to this Section 8 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

         9.       Miscellaneous. Notice given pursuant to any of the provisions
of this Agreement shall be in writing and, unless otherwise specified, shall be
mailed or delivered (a) if to the Company, at the office of the Company, Five
Mountain Road, Framingham, Massachusetts 01701, Attention: President, and (b) if
to the Underwriters, to the Representatives at the offices of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019, Attention:
Corporate Finance Department. Any such notice shall be effective only upon
receipt. Any notice under Section 7 or 8 may be made by telex or telephone, but
if so made shall be subsequently confirmed in writing.

         This Agreement has been and is made solely for the benefit of the
several Underwriters and the Company and of the controlling persons, directors
and officers referred to in Section 6, and their respective successors and
assigns, and no other person shall acquire or have any right under or by virtue
of this Agreement. The term "successors and assigns" as used in this Agreement
shall not include a purchaser, as such purchaser, of Shares from any of the
several Underwriters.

         Any action required or permitted to be taken by the Representatives
under this Agreement may be taken by them jointly or by PaineWebber
Incorporated.


                                     - 20 -

         The Representatives severally represent and warrant that they have been
authorized by each of the other Underwriters to enter into this Agreement on its
behalf and to act for each of them in the manner provided herein and that this
Agreement has been duly authorized, executed and delivered by the
Representatives on behalf of the other Underwriters.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE.

         This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

         In case any provision in this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining

         The Company and the Underwriters each hereby irrevocably waive any
right they may have to a trial by jury in respect of any claim based upon or

the representations and warranties of the Company set forth in Section 3 of the

NEEDHAM & COMPANY, INC.
  As Representatives of the
  several Underwriters
c/o PaineWebber Incorporated
  1285 Avenue of the Americas
  New York, New York  10019

Dear Sirs:

         In consideration of the agreement of the several Underwriters, for
which PaineWebber Incorporated, Hambrecht & Quist LLC and Needham & Company,
Inc. (the "Representatives") intend to act as Representatives, to underwrite a
proposed public offering of 3,000,000 shares of Common Stock, $.01 par value per
share (the "Common Stock"), of Genzyme Transgenics Corporation, a Massachusetts
corporation, as contemplated by a registration statement with respect to such
shares filed with the Securities and Exchange Commission on Form S-1
(Registration No. 333-___), the undersigned hereby agrees that the undersigned
will not, for a period of [365] days after the date of the Prospectus in
connection therewith, without the prior written consent of the Representatives,
offer to sell, sell, contract to sell, grant any option to sell or otherwise
dispose of, or require the Company to file with the Securities and Exchange
Commission a registration statement under the Securities Act of 1933, as
amended, to register any shares of Common Stock, or securities convertible into
or exchangeable for shares of Common Stock or warrants or other rights to
acquire shares of Common Stock of which the undersigned is now, or may in the
future become, the beneficial owner (within the meaning of Rule 13d-3 under the
Securities Exchange Act of 1934).



                                Very truly yours,

                                By:

                                                                       EXHIBIT C


                               Form of Opinion of
                             Counsel to the Company


         1. Each of the Company and each of its Subsidiaries is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. Each of the Company and each of its
Subsidiaries is duly licensed or qualified to do business and is in good
standing as a foreign corporation in all jurisdictions in which the nature of
the activities conducted by it or the character of the assets owned or leased by
it makes such licensing or qualification necessary, except where the failure to
be so licensed or qualified would not have a material adverse effect on the
business, properties, business prospects, condition (financial or otherwise), or
results of operations of the Company and its Subsidiaries, taken as a whole (the
"Business of the Company"). Each of the Company and each of its Subsidiaries has
full power and authority to conduct all the activities conducted by it, to own
or lease all the assets owned or leased by it and to conduct its business as
described in the Registration Statement and the Prospectus.

         2. The outstanding shares of Common Stock have been duly authorized and
validly issued and are fully paid and nonassessable and are not subject to any
preemptive or similar right.

         3. The Shares sold to the Underwriters pursuant to the Underwriting
Agreement have been duly authorized and validly issued by the Company and are
fully paid and nonassessable; and no holder thereof is subject to personal
liability by reason of being such a holder.

         4. The issuance of the Shares by the Company is not subject to
preemptive rights of any holder of securities of the Company.

         5. No consent, approval, authorization or order of, or any filing or
declaration with, any court or government agency or body is required in
connection with the authorization, issuance, transfer, sale or delivery of the
Shares by the Company, in connection with the execution, delivery and
performance of the Underwriting Agreement by the Company or in connection with
the taking by the Company of any action contemplated thereby, except such as
have been obtained under the Act and the Rules and Regulations and such as may
be required under the by-laws and rules of the NASD in connection with the
purchase and distribution by the Underwriters of the Shares. All references in
this opinion to the Underwriting Agreement shall include the Price Determination
Agreement.

         6. The authorized capital stock of the Company is as set forth in the
Registration Statement and the Prospectus. The description of the Company's
Common Stock contained in the Prospectus conforms to the terms thereof contained
in the Company's articles of organization.
<PAGE>   28
         7. The Registration Statement and the Prospectus comply in all material
respects as to form with the requirements of the Act and the Rules and
Regulations (except that we express no opinion as to financial statements,
schedules and other financial and statistical data contained in the Registration
Statement or the Prospectus).

         8. We have participated in the preparation of the Registration
Statement and the Prospectus. Except as explicitly provided herein, we have not
undertaken to verify independently the facts disclosed in the Registration
Statement and the Prospectus. However, in the course of such participation
nothing has come to our attention which has caused us to believe that (i) the
Registration Statement, at the time the Registration Statement became effective,
contained any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading and (ii) the Prospectus or any supplement thereto, at the
time the Prospectus or any supplement thereto was issued or on the date hereof,
contained or contains any untrue statement of a material fact or omitted or
omits to state any material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading (except that we express no opinion as to
financial statements, schedules and other financial or statistical data
contained in the Registration Statement or the Prospectus).

         9. The Registration Statement has become effective under the Act and,
to the best of our knowledge, no order suspending the effectiveness of the
Registration Statement has been issued and no proceeding for that purpose has
been instituted or is threatened, pending or contemplated.

         10. We have reviewed all contracts and other documents referred to in
the Registration Statement and the Prospectus, and the descriptions thereof
(insofar as such descriptions constitute a summary of the legal matters referred
to therein) are accurate in all material respects. After due inquiry, we do not
know of any contracts or other documents required to be so summarized or
disclosed or filed as an exhibit to the Registration Statement which have not
been so summarized or disclosed or filed.

         11. All descriptions in the Prospectus of statutes and regulations and,
to the best of our knowledge, of legal or governmental proceedings are accurate
and fairly present the information shown therein.

         12. The Company has full corporate power and authority to enter into
the Underwriting Agreement, and the Underwriting Agreement has been duly
authorized, executed and delivered by the Company.

         13. The execution and delivery of the Underwriting Agreement by the
Company, the consummation by the Company of the transactions therein
contemplated and the compliance by the Company with the terms of the
Underwriting Agreement do not and will not result in the creation or imposition
of any lien, charge or encumbrance upon any of the assets of the Company or any
of its Subsidiaries pursuant to the terms or provisions of, or result in a
breach or violation of any of the terms or provisions of, or constitute a
default or result in the acceleration of any obligation under, the articles of
organization or by-laws of the Company or
<PAGE>   29
any of its Subsidiaries, or any indenture, mortgage, deed of trust, voting trust
agreement, loan agreement, bond, debenture, note agreement or other evidence of
indebtedness, lease, contract or other agreement or instrument known to us to
which the Company or any of its Subsidiaries is a party or by which any of the
Company's or any of its Subsidiaries' properties is bound or affected, or any
judgment, ruling decree or order known to us or any statute, rule or regulation
applicable to the business or properties of the Company or any of its
Subsidiaries.

         14. Delivery of certificates for the Shares will pass valid and
marketable title thereto free and clear of any liens, encumbrances or claims to
each Underwriter that has purchased such Shares in good faith without knowledge
or reason to know of any adverse claims thereto and we are not aware, after due
inquiry, of any adverse claim with respect thereto.

         15. We know of no actions, suits or proceedings pending or threatened
against or affecting the Company or any of its Subsidiaries or any of their
respective officers in their capacities as such, before or by any Federal or
state or foreign court, commission, regulatory body, administrative agency or
other governmental body, wherein an unfavorable ruling, decision or finding
would materially and adversely affect the Company, any of its Subsidiaries or
the Business of the Company, except as set forth in or contemplated by the
Registration Statement and the Prospectus.

         16. To the best of our knowledge, neither the Company nor any of its
Subsidiaries is in violation of its articles of organization or by-laws or in
default (nor has an event occurred which with notice or lapse of time or both
would constitute a default or acceleration) in the performance of any
obligation, agreement or condition contained in any indenture, mortgage, deed of
trust, voting trust agreement, loan agreement, bond, debenture, note agreement
or other evidence of indebtedness, lease, contract or other agreement or
instrument known to us to which the Company or any of its Subsidiaries is a
party or by which they or their respective properties are bound or affected and
neither the Company nor any of its Subsidiaries is in violation of any judgment,
ruling, decree, order, franchise, license or permit known to us or any statute,
rule or regulation applicable to the business or properties of the Company or
any of its Subsidiaries, where such violation or default would have a material
adverse effect on the Business of the Company.

         17. The Company is not an "investment company" or an "affiliated
person" of, or "promoter" or "principal underwriter" for, an "investment
company," as such terms are defined in the Investment Company Act of 1940, as
amended.

         18.      The Shares have been duly authorized for quotation on
the NASDAQ National Market System upon official notice of
issuance.

         19. Each of the Transfer Agreement and the Development Agreement has
been duly authorized, executed and delivered by each of the parties thereto and
is enforceable against Genzyme in accordance with its terms, subject to
applicable bankruptcy and other similar laws affecting creditors' rights
generally and to general principles of equity. All consents or waivers required
in order to effectively assign, transfer or sublicense to the Company Genzyme's
rights (i) to the patent applications and licenses included in the Transferred
<PAGE>   30
Technology (as defined in the Transfer Agreement) including, without limitation,
those set forth in Schedule I to the Transfer Agreement and (ii) in the
Contracts (as defined in the Transfer Agreement) set forth in Schedule III to
the Transfer Agreement, have been obtained.

         In rendering the foregoing opinion, counsel may rely as to matters of
fact, to the extent they deem such reliance proper, on certificates of officers
of the Company and of government officials. Copies of all such certificates
shall be furnished to counsel to the Underwriters on the Closing Date. Such
counsel may state that they are not passing on matters relating to patents and
trademarks or federal or state regulation of healthcare products. Such counsel
may also state that their opinion is limited to the laws of the Commonwealth of
Massachusetts (other than the securities or Blue Sky laws thereof), the General
Corporation Law of the State of Delaware and the Federal laws of the United
States.

                               Form of opinion of
                                  Mark A. Hofer


         1. I have studied and agree with the statements in the Prospectus under
the captions "Risk Factors -- Uncertainty Regarding Patents and Protection of
Proprietary Technology," "Risk Factors --Government Regulations," "Business --
Patents and Proprietary Rights", "Business -- Government Regulation,"
"Business--Legal Proceedings" and [ ].

         2. I do not know of any pending or threatened legal or governmental
proceeding relating to patents or proprietary know-how owned or used by the
Company or any of its Subsidiaries, to which the Company or any of its
Subsidiaries is a party or to which any of the properties of the Company or any
of its Subsidiaries is subject which, if adversely decided, would have a
material adverse effect on the business, financial condition or results of
operations of the Company or any of its Subsidiaries.

         3. I have no knowledge of any infringement or alleged infringement by
the Company or any of its Subsidiaries of issued patent rights of others which
would have a material adverse effect on the business, financial condition or
results of operations of the Company and its Subsidiaries, taken as a whole.

         4. To the best of my knowledge, each of the Company and each of its
Subsidiaries possesses all governmental licenses, permits, consents, orders,
approvals and other authorizations necessary to carry on their respective
businesses as now conducted and as described in the Prospectus, except for those
the absence of which will not have a material adverse effect on the business,
financial condition or results of operations of the Company and its
Subsidiaries, taken as a whole.

Genzyme Transgenics Corporation
Five Mountain Road
Framingham, Massachusetts 01701


     We are rendering this opinion in connection with the Registration
Statement on Form S-1 (the "Registration Statement") filed by Genzyme
Transgenics Corporation (the "Company") with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, on or about the date
hereof. The Registration Statement relates to up to 3,450,000 shares of the
Company's Common Stock, $0.01 par value (the "Shares"). We understand that the
Shares are to be offered and sold in the manner described in the Registration
Statement. 

     We have acted as your counsel in connection with the preparation of the
Registration Statement. We are familiar with the proceedings of the Board of
Directors in connection with the authorization, issuance and sale of the Shares
(the "Resolutions"). We have examined such other documents as we consider
necessary to render this opinion.

     Based upon the foregoing, we are of the opinion that the Shares have been
duly authorized and, when issued and delivered by the Company against payment
therefor at the price to be determined pursuant to the Resolutions, will be
validly issued, fully paid and non-assessable.

     We hereby consent to the filing of this opinion as a part of the
Registration Statement and to the reference to our firm under the caption
"Legal Matters" in the Prospectus filed as part thereof.


                                  Very truly yours,

                                                                Exhibit 10.31.2

                               FIRST AMENDMENT TO
                              CONVERTIBLE DEBT AND
                         DEVELOPMENT FUNDING AGREEMENT

     THE CONVERTIBLE DEBT AND DEVELOPMENT FUNDING AGREEMENT dated as of March
29, 1996 made between Genzyme Transgenics Corporation ("GTC"), a Massachusetts
corporation, and Genzyme Corporation ("Genzyme"), a Massachusetts corporation
(the "Original Agreement") is hereby amended, effective as of May 3, 1996, as
follows: 

       1.   Section 2.3 of the Original Agreement is deleted in its entirety and
replaced with the following:

            2.3.    TERMINATION OF CO-MARKETING RIGHTS.  All of Genzyme's
Co-Marketing Rights shall terminate, and all of GTC's rights to AT-III under
the AT-III Agreement shall revert exclusively to GTC, upon the occurrence of any
of the following events:

            (a)  GTC's entry into an agreement with Centeon on terms equal to
or more advantageous to GTC than this Agreement (which agreement shall include
funding of the R&D Program retroactively from January 1, 1996 in accordance
with Section 1.10 of this Agreement) within 90 days of the date of this
Agreement; 

            (b)  failure of Genzyme to enter into a Supply Agreement with GTC
pursuant to Section 2.4 below by March 31, 1997; or

            (c)  at the option of GTC, upon receipt by GTC prior to the earlier
of the execution of the Supply Agreement or March 31, 1997 of a bona fide offer
from a party other than Genzyme to fund development of AT-III on terms more
favorable to GTC than this Agreement, which offer shall also include funding of
the R&D Program retroactively from January 1, 1996 in accordance with Section
1.10 of this Agreement; provided, however, that GTC's right to enter into an
agreement on the basis of any such bona fide offer shall be subject to
Genzyme's option right pursuant to Section 2.6 of this Agreement.

     In the event that Genzyme's Co-Marketing Rights are terminated pursuant to
subsection (a) of this Section 2.3, Genzyme shall be entitled to prompt payment

AGREEMENT

THIS AGREEMENT (the "Agreement") is made on the date of signature below by and
between GENZYME TRANSGENICS CORPORATION ('GTC"), with offices at One Mountain
Road, Framingham, Massachusetts 01701-9322, and BRISTOL-MYERS SQUIBB COMPANY
("BMS"), with offices at Route 206 and Province Line Road, Princeton, New
Jersey  08543.


BACKGROUND

Bristol-Myers Squibb Company "BMS) is a company actively involved in the
development and production of monoclonal antibodies using mammalian cell culture
and other technologies.

BMS believes that some future therapeutic treatments of diseases including
cancers using monoclonal antibodies will be satisfied by recombinantly sourced
antibodies. Consequently, BMS is interested in evaluating technologies providing
recombinantly sourced antibodies, including transgenic technology.

Genzyme Transgenics Corporation (GTC) has expertise in developing transgenic
production processes, beginning with small mammal feasibility studies, and
leading potentially to full scale manufacturing. GTC has successfully expressed
a number of proteins in mice (including monoclonal antibodies) and some of these
in rabbits or goats.

BMS has a monoclonal antibody, BR96, which it conjugates to doxorubicin and the
resulting product, has indication as an anti-cancer tumor therapy, which is
currently in Phase I clinical trials. The antibody is currently produced in
myeloma cells, and was efficacious in animal trials.

BMS is interested in having GTC perform a development project to express the
BR96 monoclonal antibody ("BR96") in transgenic goat milk (the "Project"), nd
GTC is interested in performing such a Project, all in accordance with the terms
and conditions set forth herein.


OBJECTIVE

To produce a number of transgenic founder goats expressing fully processed,
functional BR96 in their milk, at levels which will be economically viable as
production animals and provide the basis for a commercial-scale manufacturing
process.

In this event, BMS will consider a pivotal switch to a transgenically produced
BR96 for continuing clinical trials and large scale manufacturing.


                                        1
<PAGE>   3
The success criteria to the project will be met and the project concluded upon
demonstration that founder females, and female progeny of male founders, produce
in the ordinary course mil, containing fully processed, functional BR96 in
concentrations of not less than 0.1 g/l and delivery of reasonable quantities of
examples of such milk to BMS, provided that GTC uses all reasonable efforts to
achieve such criteria within the "Timeline" as hereinafter provided. GTC makes
no guarantee that such success criteria can be attained.


FACT FILE ON BR96

- -        BR96 is a human or humanized antibody.

- -        BMS can supply either gDNA or cDNA sequences for both heavy
         and light chains.

- -        BR96 requires correct processing and assembly, and must be
         glycosylated to confer bioactivity.

- -        The ultimate volume requirements will be in the range of
         hundreds of kilograms of BR96 per annum.

- -        The final BR96 product will have to be at least 95% pure, with no
         single contaminant comprising more than 2% of the total impurity.


GOAT DEVELOPMENT PROJECT OUTLINE

GTC will provide personnel, facilities and resources as required to perform the
Project.

GTC agrees to engineer constructs using two gDNA or cDNA sequences supplied to
GTC by BMS, one sequence coding for the BR96 light chain, and the other for the
heavy chain. These should be supplied by BMS prepared for one step ligation into
GTC's expression vectors. The sequences will be checked and will be inserted
into GTC's B-casein expression vectors.

In the event that the genes supplied by BMS are not suitable for one step
ligation into GTC's expression vectors, GTC shall offer BMS the option of
either: (a) modifying the genes to meet GTC's specified requirement or (b)
having GTC modify the genes to meet GTC's specified requirement. In the event
BMS selects option (b), BMS agrees to pay GTC upon submission of invoices 150%
of GTC's full costs incurred in undertaking this additional work.

These constructs will be either co-injected, or ligated and injected in tandem,
into suitable numbers of goat embryos which would normally be expected to yield
sixty live births, 10% of which GTC would reasonably expect to be transgenic.


                                        2
<PAGE>   4
Therefore, GTC would expect to generate six founders transgenic for BR96.

The Project may be extended to include expression of alternative gene sequences
if deemed necessary.

GTC can give no guarantee of generating the desired number of founders, or any
founders at all in the event that the gene or protein derived from it proves to
have lethal or deleterious effects on the goats.


ADDITIONAL ACTIVITIES

As an additional study within this development project, GTC will use best
endeavors to purify BR96 expressed in transgenic goat milk, to greater than 90%
purity, providing that BR96 is successfully expressed in transgenic goat milk as
a result of this program. GTC will use the best technology currently available
to it as a result of its protein purification development work. For the
avoidance of doubt, GTC will not specifically undertake a purification process
development project for BR96 within the scope of this goat development program
and Agreement.

TO BE SUPPLIED BY BRISTOL-MYERS SQUIBB

- -        gDNA and/or cDNA genes coding for the BR96 light and heavy chains as
         determined by BMS, suitable for one step ligation into GTC's B-casein
         vectors. Specifically, the genes should be prepared so that they can be
         cloned as SalI or XhoI inserts into GTC's B-casein vectors. Also, the
         genes should contain no internal SalI, XhoI or NotI sites.

- -        Available sequence data and relevant proprietary background
         information, for example, is the 5' region optional for high level
         expression, or is there a Kozak sequence around the initiating ATG, and
         no up stream ATG's.

- -        A small amount of BR96 for use as standards in any assays.

- -        Assay procedures and reagents useful to GTC for analysis of goat milk
         to determine expression level and activity of BR96, as available. ELISA
         and Western blotting are commonly used.

- -        Any information related to expression of BR96 in tissue culture, and
         any other relevant expression information.

CERTAIN RESTRICTIONS

GTC shall not use, nor shall it permit any third party to use, any gDNA, cDNA,
BR96 or other material provided by BMS, or any material derived herefrom, or any
male or female transgenic goat produced hereunder, for any purpose or otherwise
for its own or any third party's benefit, except as contemplated hereby solely
for BMS's benefit.

PAYMENT

In consideration of GTC conducting the Project, BMS will pay GTC as described
below:

(a)      BMS will pay GTC a base fee of $   *   in three payments
         as follows:

         (i)      $   *   upon execution of this Agreement by both
                  parties.

CONFIDENTIAL MATERIALS OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.  ASTERISKS DENOTE SUCH OMISSIONS.


                                        4
<PAGE>   6
         (ii)     $   *    upon completion of the micro injection of a
                  suitable number of goat embryos which would normally be
                  expected to yield 60 live births, and transfer of such
                  embryos to recipient female goats.

         (iii)    $   *    upon birth and identification of the first
                  goat kid transgenic for both heavy and light chain of
                  BR96 antibody born from the successful transfer of all
                  embryos injected with BR96 constructs.

(b)      in addition, and if applicable, BMS will pay GTC a success
         fee as set forth below within thirty (30) days after GTC
         demonstrates to BMS the successful coexpression of the
         injected BR96 constructs, as follows:

         (i)      $   *    for an expression level equal to or greater
                  than  * , but less than  *  g/l; or

         (ii)     $   *    for an expression level equal to or greater
                  than  * , but less than  *  g/l; or

         (iii)    $   *    for an expression level equal to or greater
                  than  *  g/l.

For avoidance of doubt, BMS's payment of such success fee is one time only,
under clause A., B., or C., whichever first is demonstrated to be applicable;
"g/l" refers to concentration of fully processed, functional BR96 contained in
milk produced by one or more goats in the ordinary course, as BMS can
independently verify by assaying milk samples provided by GTC.

COMMENCEMENT AND DURATION

At the date of issue of this agreement, GTC would be able to undertake this
Project following signature of the agreement, and beginning in March 1995.

Liter volumes of milk from each founder would be available and supplied to BMS
from approximately 20 months through to 32 months later.

A final report and recommendation of which germ line to pursue for herd
development would be available after 32 months maximum.

GTC shall provide BMS with written interim reports, not less frequently than
semi-annually, on the progress and status of the project hereunder. Upon
reasonable inquiries from time to time, GTC shall also provide oral progress
updates to BMS.

FURTHER DEVELOPMENT PROJECTS AND OBLIGATIONS

GTC may have the ultimate objective of manufacturing BR96 for BMS in large
animals in some form of supply agreement, the terms and conditions of which
would be worked out. If the Project is deemed successful, and BMS decides to
continue with the development of a transgenic animal manufacturing process for
BR96, the parties agree to commence in good faith negotiations in an effort to
reach agreement for GTC to manufacture BR96 and supply it to BMS at agreed
specifications and price. GTC and BMS undertake to use good faith efforts to
reach fair and reasonable terms for such an agreement, it being understood that
neither party shall be obligated to enter into such an agreement.

                  the right to perform the work as described and set forth in a
                  bona fide proposal presenting all relevant material terms. If
                  GPE decides it is not interested, it shall promptly so inform
                  GTC and the license rights granted GTC under Section 2.2 shall
                  be extended to include cattle for such protein. If GPE decides
                  it is interested, it shall deliver in good faith its response
                  proposal to GTC within 60 days; failure to substantively
                  respond within that time period to all material terms of the
                  proposal shall be deemed an expression of no interest. GTC may
                  in the exercise of its reasonable judgment either accept the
                  GPE response proposal or decide not to accept and instead have
                  the work performed by a third party or itself. In the event
                  GTC has decided not to accept the proposal, the license rights
                  granted GTC under Section 2.2 shall be extended to include
                  cattle for such protein, subject, however, to a royalty
                  payable hereunder to GPE pursuant to a royalty rate of X, and
                  the revenue, payment, reporting and audit terms as set forth
                  in the Biogen License (as defined in Section 4.1 as modified
                  by Section 4.2) mutatis mutandis; where "X" is   *  % if
                  both the Biogen and Rosen Patents cover the product in
                  question, but if only the Rosen Patents cover the product in
                  question, then X is the royalty rate scheme as set forth in
                  the Biogen License (i.e.,   *  %) plus   *  % so that the
                  resultant royalty shall be   *  % operating in similar
                  manner as the royalty scheme set forth in Appendix C of the
                  Biogen License. The parties agree, however, that in no event
                  will the royalty due GPE on the sales of product ever exceed
                    *  % in total under this and the Biogen License agreements.

         2.5.     Rights of First Opportunity for GTC to Work in Goats

                  2.5.1. No license rights are granted under any circumstances
                  to GPE or its Affiliates in the Field with respect to the
                  manufacture, use and sale of transgenic goats to produce human
                  antithrombin-III and/or cystic fibrosis transmembrane
                  conductance regulator.

                  2.5.2. If GPE wishes to produce a particular protein in the
                  Field in goats, it shall first approach GTC and provide GTC
                  the right to perform the work as described and set forth in a
                  bona fide proposal presenting all relevant material terms. If
                  GTC decides it is not interested, it shall promptly so inform
                  GPE and the license rights granted GPE under Section 2.1 shall
                  be extended to include goats for such protein. If GTC decides
                  it is interested, it shall deliver in good faith its response
                  proposal to GPE within 60 days; failure to substantively
                  respond within that time period to all material terms of the
                  proposal shall be deemed an expression of no interest. GPE may
                  in the exercise of its reasonable judgment either accept the
                  GTC response proposal or decide not to accept it and instead
                  have the work performed by a third party or itself. In the
                  event GPE has decided not to accept the proposal, the license
                  rights granted GPE under Section 2.1 shall be extended to
                  include goats for such protein, subject, however, to a royalty
                  payable to GTC pursuant to a royalty rate of *% and the
                  revenue, payment, reporting and audit terms as set forth in
                  the Biogen License (defined in Section 4.1 as modified by
                  Section 4.2) mutatis mutandis.

3.0      PATENT PROSECUTION AND MAINTENANCE

         3.1.     GTC and GPE will each bear the responsibility and cost for the
                  filing, maintenance and prosecution of their respective Patent
                  Rights. At each party's sole discretion, each party may elect
                  not to file, maintain or prosecute a patent or patent
                  application within its patent Rights. In the event that one
                  party elects not to file, maintain or prosecute, the other
                  party, at its expense, will have the option to proceed with
                  the filing, maintenance or prosecution on the declining
                  party's behalf. Both parties agree to cooperate in the filing,
                  maintenance and prosecution of such patent applications taken
                  on by the other party. Notwithstanding anything herein to the
                  contrary, nothing herein shall be construed to grant either
                  party any rights of enforcement under the Patent Rights of the
                  other party.

4.0      BIOGEN PATENTS

         4.1.     GTC agrees concurrent with the execution hereof to provide
                  written consent to Biogen to assign (i) the Biogen Patents to
                  GPE pursuant to an agreement (the "GP-Biogen Purchase
                  Agreement"), such assignment subject to the existing rights
                  and obligations of GTC pursuant to its license agreement with
                  Biogen (assigned from Genzyme Corporation) dated December 26,
                  1990 (the "Biogen License") and (ii) the Biogen License to GPE
                  (as amended pursuant to Section 4.2 below). GPE hereby
                  represents that the only provisions which reference, describe
                  or are directly related to GTC or Genzyme Corporation in the
                  GP-Biogen Purchase Agreement are set forth as Attachment 1 to
                  this Agreement.


         4.2.     The parties agree that the Biogen License shall be and is
                  hereby amended to have the following effects:

                           Patents are invalidated as a result of a US patent
                           interference with any claims of the Rosen Patents,
                           then the corresponding claims from the Rosen Patent
                           shall be substituted in the Biogen License and the
                           terms thereof shall govern GTC's rights and
                           obligations under such claims of the Rosen Patents.

5.0      MISCELLANEOUS

         5.1.     The term of the respective licenses granted hereunder shall be
                  for a period beginning with the effective date hereof and
                  ending with the last to expire of the applicable GTC or GPE
                  Patent Rights.

         5.2.     Either party may terminate this Agreement or the license
                  granted to the other party hereunder if, at any time, the
                  other party shall file in any court pursuant to any statute of

                  creditors or for the appointment of a receiver or trustee of
                  the party or of its assets, or if the other party proposes a
                  written agreement of composition or extension of its debts, or
                  if the other party shall be served with an involuntary
                  petition against it filed in any insolvency proceeding, and
                  such petition shall not be dismissed within sixty (60) days
                  after the filing thereof, or if the other party shall propose
                  or be a party to any dissolution or liquidation, or if the
                  other party shall make an assignment for the benefit of
                  creditors, or if upon 60 days written notice, the other party
                  fails to correct a material default specified in such notice.

         5.3.     GTC and GPE make no warranty that the manufacture, use or sale
                  of heterologous proteins made in the milk of transgenic
                  animals will not constitute an infringement of the
                  intellectual property rights of patents not licensed hereunder
                  or of the rights
<PAGE>   6
                  of others, or that applications or claims included within GTC

                  Agreement and to grant the rights granted herein. Each party
                  recognizes and acknowledges that (i) the only licenses granted
                  under this Agreement are limited to the GTC Patent Rights and
                  GPE Patent Rights and (ii) no protein specific rights are
                  granted to the other party under this Agreement.

         5.4.     GTC hereby represents that any rights it obtains under this
                  Agreement shall not flow to the benefit of Pharmaceutical
                  Proteins Ltd. or its Affiliates by virtue of any agreement

                  Affiliates.

         5.5.     The official language of this Agreement shall be the English

         5.6.     The parties agree to negotiate and attempt to settle, in good
                  faith, any disputes arising out of this Agreement. If the
                  parties are unable to come to an agreement, the dispute shall
                  be finally settled by arbitration conducted in Paris, France
                  in accordance with the rules of conciliation and arbitration
                  of the International Chamber of Commerce then in effect. The
                  arbitrator shall apply the laws of the State of New Jersey,
                  U.S.A. Both parties shall bear their own costs. Any award by

                  parties and unappealable by either, and each party submits
                  itself to the jurisdiction of the courts sitting in the other
                  party's jurisdiction for entry of judgment with respect to the
                  decision of the arbitrator. The award may also be entered in
                  and enforceable by any other court having jurisdiction over
                  the parties.

         5.7.     GTC agrees to use all commercially reasonable efforts to cause
                  its joint venture in the Far East to enter into an agreement
                  substantially of the same form as this Agreement for the Far
                  East. GPE agrees to reasonably cooperate in that effort and to
                  enter into such an agreement for the Far East.

         5.8.     Any notice, request, approval or other document required to be
                  given under this Agreement shall be in writing and shall be

         We are rendering this opinion in connection with the Registration
Statement on Form S-1 (the "Registration Statement") filed by Genzyme
Transgenics Corporation (the "Company") with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, on or about the date
hereof. The Registration Statement relates to up to 3,450,000 shares of the
Company's Common Stock, $0.01 par value (the "Shares"). We understand that the
Shares are to be offered and sold in the manner described in the Registration
Statement.

         We have acted as your counsel in connection with the preparation of the
Registration Statement. We are familiar with the proceedings of the Board of
Directors in connection with the authorization, issuance and sale of the Shares
(the "Resolutions"). We have examined such other documents as we consider
necessary to render this opinion.

         Based upon the foregoing, we are of the opinion that the Shares have
been duly authorized and, when issued and delivered by the Company against
payment therefor at the price to be determined pursuant to the Resolutions, will
be validly issued, fully paid and non-assessable.

         We hereby consent to the filing of this opinion as a part of the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the Prospectus filed as part thereof.

                                                 Very truly yours,



                                                 Palmer & Dodge LLP
