PART I
Item 1. BUSINESS

A. General

T Cell Sciences, Inc. (the "Company," "T Cell" or "TCS") is a biopharmaceutical
company creating value by using novel applications of immunology to prevent and
treat cardiovascular, pulmonary and immune disorders. The Company's technology
platforms are based on its understanding of the ways in which the body triggers
its natural defense mechanisms. The Company's product development efforts are
focused on three therapeutic programs. The most advanced program, which includes
clinical trials with T Cell Sciences' lead product TP10, focuses on compounds
that inhibit the inappropriate activation of the complement cascade in a variety
of acute and chronic diseases. Second, the Company is engaged in the discovery
and development of T cell activation regulators for the prevention of transplant
rejection and treatment of autoimmune disorders. The Company's third program
focuses on the development of a therapeutic vaccine for the management of
atherosclerosis, one of the leading causes of death worldwide.

In 1996, the Company realigned certain of its operations to focus on these three
ongoing therapeutic drug discovery programs. The Company sold the operations and
research product line of its wholly owned subsidiary, T Cell Diagnostics, Inc.
("TCD") to Endogen, Inc. ("Endogen"), while retaining the TRAx(R) diagnostic
product franchise (see Section C: "Diagnostic Business"). T Cell has outsourced
distribution and manufacture of TRAx products, which are used primarily for
monitoring T cell levels in HIV-infected individuals.

During the past year, T Cell received three grants totaling $874,000 in support
of the development of its cholesterol-lowering cholesteryl ester transfer
protein ("CETP") vaccine for the prevention and treatment of atherosclerosis.
(See Section B: "Therapeutic Drug Discovery Programs" Item 3. "CETP Vaccine").
In February 1997, the National Institutes of Health ("NIH") awarded the Company
a $100,000 Phase I Small Business Innovation Research ("SBIR") grant for the
development of a novel plasmid-based vaccine to prevent or treat
atherosclerosis. In September 1997, the Company was awarded a $678,000 Phase II
SBIR grant which provides funding over a two year period for the development of
a novel transgenic rat model of atherosclerosis. In January 1998, T Cell
received a $96,000 Phase I grant for the development of a novel peptide vaccine
to prevent or treat atherosclerosis. In preclinical studies, rabbits treated
with the vaccine showed an improvement in the balance of cholesterol between HDL
(high-density lipoprotein, or "good" cholesterol) and LDL (low-density
lipoprotein, or "bad" cholesterol). When fed a high fat diet, vaccinated rabbits
exhibited reduced atherosclerotic lesions in their blood vessels compared with
untreated rabbits.

In June 1997, the Company received a milestone payment from its corporate
partner, Astra AB ("Astra"), as one of the products derived from the Company's T
cell antigen receptor ("TCAR") program entered clinical trials for the treatment
of multiple sclerosis (see Section B: "Therapeutic Drug Discovery Programs" Item
4. "T Cell Antigen Receptor"). The product, ATM027, a humanized monoclonal
antibody, represents the Company's second drug candidate to enter human testing.
In February 1998, the Company announced progress from the Phase I clinical
trial. Astra, which is conducting the development of ATM027, announced that
Phase I data has shown an effect on the target cells and there have been no
serious adverse effects in the study to date. Astra also announced that it is
scheduling Phase II studies to begin later in 1998.

-2-


In October 1997, the Company presented positive preliminary results from the
efficacy portion of its Phase I/II clinical trial of its lead therapeutic
compound, TP10 (see Section B: "Therapeutic Drug Discovery Programs" Item 1.
"Complement Inhibition"). The trial was aimed at evaluating the ability of TP10
to reduce reperfusion injury and improve lung function in patients with
end-stage pulmonary disease who had undergone lung transplant surgery. The
preliminary results showed that fewer patients receiving TP10 required
ventilation 24 hours after surgery compared to control patients. Treated
patients undergoing cardiopulmonary by-pass as part of the transplantation
procedure showed significantly decreased intubation time and time on ventilation
and a trend toward reduced time in the intensive care unit. Final trial results,
including an analysis of the six-month safety review which concluded in November
1997, are scheduled for presentation in April 1998 at the International Society
of Heart and Lung Transplantation conference.

Also in October 1997, T Cell announced that it had entered into an option
agreement with Novartis Pharma AG relating to the development of TP10 for use in
xenotransplantation (animal organs into humans) and allotransplantation (human
to human). The option agreement provides for annual option fees and supplies of
TP10 for clinical trials, the combination of which are valued at up to
$5,000,000, in return for granting a two-year option to license TP10 with
exclusive worldwide marketing rights (except Japan) in xenotransplantation and
allotransplantation. Should Novartis exercise its option to license TP10 and
continue development, it will provide an equity investment, licensing fees and
milestone payments based upon attainment of certain development and regulatory
goals. The combined option agreement and license is valued at up to $25,000,000.
Additionally, T Cell may receive funding for research as well as royalty
payments on any eventual product sales.

In October 1997, T Cell announced a collaboration designed to utilize the
Company's proprietary T cell screening and functional assay technology platform
to identify small molecule immunoregulatory therapeutic compounds (see Section
B: "Therapeutic Drug Discovery Programs", Item 2. "Small Molecule
Immunoregulators"). The strategic alliance with Repligen, Inc. will provide
access to Repligen's proprietary, combinatorial chemical library.

In November 1997, T Cell announced that it had reached a settlement of its
outstanding litigation with Forest City, its former landlord at 38 Sidney Street
in Cambridge, Massachusetts and PNC Bank, N.A., the landlord's mortgagee. T Cell
agreed to pay a total of $2,358,800 in cash with $858,800 payable on November
17, 1997 and additional payments of $750,000 each on November 16, 1998 and
November 15, 1999. In addition, T Cell agreed to issue a total of 1,500,000
shares of its common stock to Forest City and to exchange mutual releases. The
settlement, valued at $6,108,800, has been recorded as non-operating expense.

In December 1997, the Company completed its Phase IIa trial evaluating the use
of the Company's lead complement inhibitor, TP10, in patients with adult
respiratory distress syndrome ("ARDS"). The Phase IIa trial was an open-label,
single-dose trial conducted at three clinical sites. The trial enrolled nine
patients with ARDS arising from a number of different medical conditions. The
trial was designed to determine the effect of TP10 on respiratory performance in
patients with ARDS and to study the ability of TP10 to improve the clinical
outcome of patients with established ARDS. The trial results showed that
patients receiving TP10 tended towards improved respiratory performance and
improved blood oxygenation. Because the trial included few patients and no
placebo control was used, no definitive claims about efficacy could be made.

During 1997, T Cell's board of directors experienced significant change as James
D. Grant, Chairman since 1986, retired along with Directors, John P. Munson and
John Simon. The Company announced the election of several new board members
during 1997 including Harry H. Penner, Jr., President and CEO of Neurogen
Corporation (January 1997), Ronald M. Urvater, Managing Partner, Aurora Capital
Corporation (June 1997) and William J. Ryan, Senior Vice President, Arquest,
Inc. and former Chairman and CEO of CytoRad, Inc. (August 1997).

In March 1998, the Company completed a financing, raising net proceeds of
approximately $3,708,000 through a private placement of approximately 2,043,000
shares of common stock. The Company has agreed to register these shares for
resale under the Securities Act of 1933, as amended.

B. Therapeutic Drug Discovery Programs

1. Complement Inhibition

T Cell's lead therapeutic program is focused on developing compounds that
inhibit a part of the immune system called the complement system. The complement
system is a series of proteins that are important initiators of the body's acute
inflammatory response against disease, infection and injury. Excessive
complement activation also plays a role in certain chronic inflammatory
conditions. When complement is activated, it helps to identify and eliminate
infectious pathogens and damaged tissue. In certain situations, however,
excessive complement activation may destroy viable and healthy tissue and tissue
which, though damaged, might recover. This excessive response compounds the
effects of the initial injury or introduces unwanted tissue destruction in
clinical situations such as organ transplants, cardiovascular surgeries and
treatment for heart attacks. Many independent, published studies have reported
that the Company's lead compound, TP10, a soluble form of naturally occurring
Complement Receptor 1 ("sCR1"), effectively inhibits the activation of the
complement cascade in animal models. The Company believes that regulation of the
complement system could have therapeutic and prophylactic applications in
several acute and chronic conditions, including reperfusion injury from surgery
or ischemic disease, organ transplant, multiple sclerosis, Alzheimer's disease,
rheumatoid arthritis, myasthenia gravis and ARDS. In the United States, several
million people are afflicted with these complement-mediated conditions.

T Cell started the complement program in 1988. From 1989 through 1994, TP10 was
under development in a joint program with SmithKline Beecham, p.l.c., ("SB") and
Yamanouchi Pharmaceutical Co. ("YPC"). During 1994, T Cell and SB negotiated
various amendments to the agreement and, in February 1995, the two companies
agreed to a mutual termination by which T Cell regained all rights to the
program except for co-marketing rights in Japan, which are retained by SB and
YPC.

Under T Cell's direction, in 1995 the first Phase I clinical trial of TP10 in 24
patients at risk for ARDS was completed. Results of this trial were presented in
October 1995 at The American College of Chest Physicians meeting. A second Phase
I safety trial for reperfusion injury was completed in December 1995 in 25
patients with first-time myocardial infarctions. This study was presented at the
American Heart Association's Joint Conference on Thrombosis, Arteriosclerosis
and Vascular Biology in February 1996. In each trial, TP10 demonstrated
excellent safety and pharmacokinetic profiles, had a terminal phase half-life of
at least 72 hours and was able to inhibit complement activity in a
dose-dependent manner.

Based on these favorable results, in January 1996, TCS initiated a Phase IIa
trial in patients with established ARDS. This trial was an open-label,
single-dose feasibility trial to determine the potential for efficacy of TP10 in
reducing neutrophil accumulation in the lungs and improved clinical outcome of
patients with ARDS. During the second half of 1996, the Company initiated a
series of steps, including broadening enrollment criteria, to modify this trial
to improve the rate of patient accrual. In December 1997, the Company completed
this Phase IIa trial after it had enrolled nine patients with ARDS arising from
a number of different medical conditions. The trial results showed that patients
receiving TP10 tended towards improved respiratory performance and improved
blood oxygenation. Because the trial included few patients and no placebo
control was used, no definitive claims about efficacy could be made.

The Company also began enrollment in a Phase I/II clinical trial in patients
undergoing lung transplantation, in August 1996. A goal of the trial was to
determine the ability of TP10 to reduce reperfusion injury and improve lung
function in patients with end-stage pulmonary disease who were undergoing lung
transplant surgery. This study was a randomized, placebo-controlled,
double-blind trial consisting of single dosages of 10 mg/kg of TP10 as an
intravenous infusion over 30 minutes. The trial was conducted at multiple
centers in North America and included a total of 60 patients. In May 1997, the
Company announced the completion of patient accrual and in October 1997, the
Company presented positive preliminary results from the efficacy portion of the
trial. The preliminary results showed that fewer patients receiving TP10
required ventilation 24 hours after surgery compared to control patients.
Treated patients undergoing cardiopulmonary by-pass as part of the
transplantation procedure showed significantly decreased intubation time and
time on ventilation and a trend toward reduced time in the intensive care unit.
Final trial results, including an analysis of the six month safety review which
concluded in
-4-


December 1997, are scheduled for presentation in April 1998 at the
International Society of Heart and Lung Transplantation conference.

In addition to TP10, TCS has identified other product candidates to inhibit
activation of the complement system. The lead candidate under research
evaluation is a form of sCR1 (TP10) which has been modified to add sLe(x)
carbohydrate structures. sLe(x) is a carbohydrate structure which mediates
binding of neutrophils to selectin proteins, which appear on the surface of
activated endothelial cells as an early inflammatory event. Selectin-mediated
binding of neutrophils to activated endothelial cells is a critical event in
inflammation. The combined sCR1sLe(x) molecule has demonstrated increased
functional benefits in in vitro and early in vivo experiments. During 1996, the
Company confirmed the presence of the desired carbohydrate structures and their
function in in vivo experiments and confirmed the presence of both
anti-complement and selectin-binding functions in in vitro experiments. During
1997, the Company produced additional sCR1sLe(x) material and began preclinical
studies in disease-relevant animal models. In November 1997, the Company
received a notice of allowance of claims from the U.S. Patent and Trademark
Office for a patent covering sCR1sLe(x).

sCR1sLe(x) may create new and expanded opportunities for the Company in
complement and selectin-dependent indications such as stroke and myocardial
infarction. The Company believes that sCR1sLe(x) has the ability to target the
complement-inhibiting activity of sCR1 to the site of inflammation and, at the
same time, inhibit the leukocyte/endothelial cell adhesion process.

2. Small Molecule Immunoregulators ("SMIR")

As a direct result of over thirteen years of experience working with T cells and
building on the Company's evaluation capabilities in molecular and cellular
immunology and small-animal immunology models, the Company has developed a
proprietary screening platform to identify small molecule compounds which can
regulate T cell activation. These whole cell screens are based on signal
transduction and gene regulation directed to cytokine gene targets. T cell
activation plays an important role in solid organ transplant rejection as well
as in certain autoimmune diseases. The Company is seeking to develop an
alternative treatment to existing immunosuppressants such as Cyclosporin and
FK506 which, due to their toxicity, have limited application. Despite this
limitation, worldwide sales of Cyclosporin in 1995 exceeded $1 billion. TCS'
basic approach is to combine the biological skills and proprietary screens it
has developed with the small molecule libraries created by other biotechnology
companies.

In March 1996, T Cell announced a series of collaboration agreements designed to
utilize the Company's proprietary T cell screening and functional assay
technology platform to identify small molecule immunoregulatory therapeutic
compounds. The Company entered into a strategic alliance with ArQule, Inc.,
which provides access to ArQule's proprietary non-peptidic small molecule
arrays. The Company also signed a collaborative agreement with MYCOsearch, Inc.,
(which was subsequently acquired by OSI Pharmaceuticals, Inc.) which enables T
Cell to screen that company's natural products libraries. In December 1997, the
Company completed its initial screening program with OSI Pharmaceuticals, Inc.
and agreed to study a series of lead compounds for further development. In
October 1997, the Company entered into a strategic alliance with Repligen, Inc.,
which provides access to Repligen's proprietary, combinatorial chemical library.
Under each of these agreements, T Cell and its partners will share rights to
compounds identified using T Cell's screens. As of March 1998, the Company has
identified a number of immunostimulator and immunosuppressor hits from its
screening activities. Further research directed to pinpointing the mechanisms of
activity, optimizing potency, and testing in animals is underway.

3. CETP Vaccine

The Company is developing a therapeutic vaccine against endogenous cholesteryl
ester transfer protein ("CETP") which may be useful in reducing risk factors for
atherosclerosis. CETP is a key intermediary in the balance of high-density
lipoprotein ("HDL" or "good" cholesterol) and low-density lipoprotein ("LDL" or
"bad" cholesterol). T Cell is developing a vaccine to stimulate an immune
response against CETP which it believes may improve the ratio of HDL to LDL
cholesterol and reduce the progression of atherosclerosis. The Company has
conducted preliminary studies of rabbits which had been administered the CETP
vaccine and fed a high-cholesterol, high-fat

-5-


diet. In these studies, vaccine-treated rabbits exhibited reduced lesions in
their blood vessels compared to a control group of untreated rabbits which
developed significant blood vessel lesions. These studies have demonstrated, in
animal models, the Company's ability to break immune tolerance, produce
autoreactive antibodies to CETP and reduce the development of blood vessel
lesions.

Atherosclerosis is one of the leading causes of morbidity and mortality in the
United States and most of the Western world. Current pharmacologic treatments
require daily administration and can result in high costs and poor patient
compliance. In 1995, the market for cholesterol-lowering drugs exceeded $4
billion worldwide. A vaccine directed at lowering CETP activity, such as the one
being developed by the Company, may offer several advantages over conventional
approaches, including requiring less frequent dosing, lower costs, reduced side
effects, and improved patient compliance.

In September 1996, the NIH awarded the Company a $100,000, Phase I SBIR grant
for the development of a novel transgenic rat atherosclerosis model, affording
better comparison to human atherosclerosis. In February 1997, the NIH awarded T
Cell a second $100,000 Phase I SBIR grant to develop a novel plasmid-based
vaccine to prevent or treat atherosclerosis. In September 1997, the Company was
awarded a $678,000 Phase II SBIR grant from the NIH which provides funding over
a two year period for the continued development of the novel transgenic rat
model of atherosclerosis. In January 1998, T Cell received a $96,000 Phase I
SBIR grant from the NIH for the development of a novel peptide vaccine to
prevent or treat atherosclerosis.

4. T Cell Antigen Receptor (TCAR)

In early 1992, TCS entered into a joint development program with Astra AB
("Astra") to develop products resulting from TCS' proprietary TCAR technology,
which utilizes the T cell antigen receptor for selectively targeting the T cells
involved in autoimmune diseases such as multiple sclerosis and rheumatoid
arthritis. The original agreement was modified in December 1993 with Astra
assuming all responsibility for the development of the lead antibody products
and TCS retaining leadership of the first peptide product candidate. Under the
original and modified agreements, TCS received funding support of approximately
$15 million in the early years with the potential of up to $17 million of
additional funding based on clinical progress. By the end of 1995, T Cell had
received substantially all of the original funding payments.

In December 1996, the Company amended its agreement with Astra to transfer
certain of its rights to the TCAR technology, including two therapeutic
products, ATM027-monoclonal and ATP012-peptide, to Astra, who will be solely
responsible for further clinical development and commercialization. Under the
amended agreement, TCS could receive royalties from product sales, as well as
milestone payments which may total up to $4 million as certain clinical
milestones are achieved.

In June 1997, the Company announced that it received a milestone payment from
Astra as one of the products derived from the Company's TCAR program entered
clinical trials for the treatment of multiple sclerosis. In February 1998, Astra
announced that Phase I data has shown an effect on the target cells and that
there have been no serious adverse effects in the study to date. Astra also
announced that it is scheduling Phase II studies to begin later in 1998. This
represents the Company's second therapeutic product to enter human testing.


C. Diagnostic Business

In March 1996, the Company realigned certain of its operations and sold the
operations and research product line of its wholly owned subsidiary, T Cell
Diagnostics, Inc. ("TCD") to Endogen, Inc. ("Endogen") for $3.0 million, while
retaining the Company's TRAx(R) diagnostic product franchise. T Cell received a
five year convertible subordinated note for $2.0 million combined with
approximately $1.0 million used to repay obligations under the Company's
operating lease. T Cell recognized a gain on this transaction of $0.3 million.
On February 10, 1997, T Cell received approximately $1.8 million following the
conversion of the remaining balance of the Endogen note into shares of Endogen
common stock, which were subsequently sold.

-6-


T Cell retained all rights to the TRAx product franchise and has agreed to
source the manufacture of TRAx kits from Endogen in a separate supply contract.
TCD signed a sales and distribution contract for the United States market with
Diamedix Corporation in December 1995. Diamedix is a wholly owned subsidiary of
Ivax Corporation with a history of selling enzyme immunoassays in the in vitro
diagnostics market. The contract covers the TRAx microtiter plate format
products. The Company has deferred filing a 510(K) application with the Food and
Drug Administration (FDA) for clearance to market TRAx CD8 in the United States
while it focuses on establishing a partnership for the TRAx technology.


D. Patents and Proprietary Rights

The successful development and marketing of products by the Company will depend
in part on its ability to create and maintain intellectual property, including
patent rights. The Company has established a proprietary patent position in the
areas of complement inhibitor molecules and diagnostic technologies, and is the
owner or exclusive licensee of numerous patents and pending applications around
the world, including 11 U.S. patents. Although the Company continues to pursue
patent protection for its products, no assurance can be given that any pending
application will issue as a patent, that any issued patent will have a scope
which will be of commercial benefit or that the Company will be able to
successfully enforce its patent position against competitors.

In the area of complement molecules, T Cell has an exclusive license to patent
rights, which it co-owns with The Johns Hopkins University and Brigham & Women's
Hospital, covering CR1 inventions. These rights are based in part on the work of
Dr. Douglas Fearon and include U.S. patents which claim the nucleic acid
sequences of recombinant CR1, soluble CR1 (sCR1) and active fragments, and
pharmaceutical uses of CR1. TCS also owns or has rights to a number of other
patent applications relating to CR1, sCR1sLe(x) and other complement inhibitor
molecules. In November 1997, the Company received a notice of allowance of
claims from the U.S. Patent and Trademark Office for a patent application
covering sCR1sLe(x).

In April 1996, the Company announced that it had licensed portions of its patent
and technology rights regarding CR1 to CytoTherapeutics, Inc. for use in
protecting CytoTherapeutics' proprietary cell-based products for the delivery of
therapeutic substances to the central nervous system.

In December 1996, the Company amended its agreement with Astra to transfer
certain of its patent rights and licenses to the TCAR technology to Astra. This
transfer includes patent applications which have resulted to date in U.S.
patents covering the DNA, protein, protein fragments and antibodies relating to
the Alpha TCAR and the DNA, full-length proteins and antibodies relating to Beta
TCAR, and two European patents covering Beta TCAR inventions. In addition, the
Company has transferred recent filings on new T cell antigen receptor inventions
resulting from the partnership with Astra.

In the area of diagnostics, T Cell is the owner of several patents relating to
TRAx CD4 and CD8 and other applications of the TRAx product technologies. The
first U.S. patent covering the TRAx CD4 and CD8 products issued on June 11,
1996. In February 1998, the Company received a notice of allowance of claims for
the U.S. Patent and Trademark Office for a patent application covering the
TRAx(R) Test Kit.

The Company is aware that others, including universities and companies, have
filed patent applications and have been granted patents in the United States and
other countries which claim subject matter potentially useful or necessary to
the commercialization of the Company's products. The ultimate scope and validity
of existing or future patents which have or may be granted to third parties, and
the availability and cost of acquiring rights to those patents which are
necessary to the manufacture, use or sale of the Company's products presently
cannot be determined by the Company.

Trade secrets and confidential know-how are important to the Company's
scientific and commercial successes. Although the Company takes measures to
protect its proprietary information, there can be no assurance that others will
not either develop independently or obtain access to this information.

-7-


E. Competition

The Company is engaged in a rapidly expanding area of biotechnology in which
research is being conducted worldwide by universities, public and private
institutions, and biotechnology and pharmaceutical companies. A number of these
entities are developing product candidates which may become competitors of the
Company's products in development. Several such companies are involved in
product development efforts aimed at treatments for autoimmune diseases and
inflammatory conditions and some are specifically developing products based on T
cell receptors and the human complement system. There can be no assurance that
the Company's products will be commercialized or that other companies,
universities and public and private foundations, among others, many of which
have greater financial resources than the Company, will not be able to develop
competing proprietary positions or products.

The Company's competitive position also depends upon its ability to attract and
retain qualified personnel, obtain patent protection or otherwise develop
proprietary technology and products, and secure sufficient capital resources to
fund product ideas to commercialization. There can be no assurance that the
Company will be successful in its efforts in these areas.


F. Government Regulation

The product testing, manufacture, safety and efficacy requirements, labeling,
storage, record keeping, approval, advertising, promotion and sale of the
Company's present and future products are closely regulated by federal and other
governmental authorities. The FDA and comparable government agencies in foreign
countries have established mandatory procedures and safety and efficacy
standards which must be met before the appropriate authority approves the
clinical testing, manufacturing and marketing of a human health care product.

The steps required before a pharmaceutical product may be marketed in the United
States include (i) in vitro and in vivo preclinical testing, (ii) submission to
the FDA of an Investigational New Drug application (IND) and clearance to begin
human clinical trials, (iii) adequate human clinical trials to establish the
safety and efficacy of the drug, (iv) the submission of a New Drug Application
("NDA") or Product License Application ("PLA") to the FDA, and (v) FDA approval
of the NDA or PLA prior to commercial sale or shipment of the product. In
addition to obtaining FDA approval for each product, each drug manufacturing
establishment must be registered with and approved by the FDA.

The steps required before an in vitro diagnostic product may be marketed in the
United States include (i) clinical trials which demonstrate that the product's
results are substantially equivalent to results obtained from a product
currently on the market, or if no product is currently marketed for the intended
use, then clinical trials which correlate assay results with the intended
clinical use, (ii) the submission of a 510(k) or Premarket Approval ("PMA")
application to the FDA, and (iii) FDA clearance to market the product. Under a
510(k) or PMA, the facility in which products are produced must comply with the
FDA's Good Manufacturing Practices regulations.

The Company's present and future business activities are and will be subject to
regulation under additional federal, state and local laws and regulations,
including regulations by the U.S. Environmental Protection Agency and the U.S.
Occupational Safety and Health Administration. The Company also will be subject
to widely varying foreign regulations governing clinical trials and
pharmaceutical sales. Whether or not FDA approval has been obtained, approval of
a product by the comparable regulatory authorities of foreign countries must be
obtained prior to the commencement of marketing of the product in those
countries. The approval process varies from country to country and the time
period may be longer or shorter than that required for FDA approval. The Company
intends to rely on foreign licensees to obtain regulatory approvals to market
products in foreign countries.

-8-



Regulatory approval often takes a number of years and involves the expenditure
of substantial resources. Approval times also depend on a number of factors,
including the severity of the disease in question, the availability of
alternative treatments and the risks and benefits demonstrated in clinical
trials.


G. Employees; Scientific Consultants

As of March 2, 1998, the Company employed 36 full time persons, 13 of whom have
doctoral degrees. Of these employees, 26 were engaged in or directly supported

Item 2. PROPERTIES

The Company leases approximately 54,000 square feet of laboratory and office
space in Needham, Massachusetts, of which it subleases approximately 13,000
square feet of excess laboratory and office space to a tenant. The lease has an
initial term of six years which expires in April 2002. Under the lease
agreement, the Company is obligated to pay a base annual rent of $676,400 until
June 1997 and $756,400 until the end of the initial term. The sublease has an
initial term of four years which expires in April 2000. Under the sublease
agreement, the Company will receive base annual subrental income of $110,500
until June 1997 and $133,600 until the end of the initial term. Aggregate net
base rental payments for the years end December 31, 1997 and 1996 for this
facility were $594,400 and $598,500, respectively.


Item 3. LEGAL PROCEEDINGS

In December 1994, the Company filed a lawsuit in the Superior Court of
Massachusetts against the landlord of its former Cambridge, Massachusetts
headquarters to recover the damages incurred by the Company resulting from the
evacuation of the building due to air quality problems, which caused skin and
respiratory irritation to a significant number of employees. The landlord
defendant filed counterclaims, alleging the Company breached its lease
obligations. The court ordered a limited trial between the Company and the
landlord on certain factual issues which began on November 20, 1996. Closing
arguments for the limited trial were heard on January 13, 1997. In a separate
lawsuit, the landlord's mortgagee filed claims against the Company for payment
of the same rent alleged to be owed. A motion for summary judgment filed by the
bank was denied by the court. In August 1997, the Superior Court of
Massachusetts entered findings of fact and conclusions of law on the limited
trial of the Company's lawsuit against the landlord. In its findings, the Court
concluded that the Company had not proved, as alleged by the Company, that any
fireproofing fibers contaminated the Company's space, the Company's space was
not uninhabitable because of contamination from fireproofing fibers and the
Company was not justified in terminating its lease on the grounds that its
office and laboratories were uninhabitable. In November 1997, the Company
reached a settlement of the litigation with its former landlord and the
landlord's mortgagee. The Company agreed to pay $858,800 in cash on November 17,
1997 and issue a total of 1,500,000 shares of its common stock. In addition, the
Company signed a note for $750,000 payable on November 16, 1998 secured by
$750,000 cash collateral and a note for $750,000 due November 15, 1999 secured
by 132,500 shares of its common stock. The total settlement, valued at
$6,108,800, is comprised of the cash and notes totaling $2,358,800 and common
stock valued at $3,750,000 as of October 31, 1997 and is included in
non-operating expense for the year ended December 31, 1997. The common stock to
be issued is subject to restrictions on transfer per the settlement agreement.
The settlement agreement also provides for certain registration rights for the
shares of common stock to become effective no later than September 30, 1998.
Upon such registration, however, the settlement agreement limits the number of
shares that may be sold over a given period of time.

Safe Harbor Statement under the Private Securities Litigation Reform
Act of 1995: Statements contained in the following, Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations, that
are not historical facts may be forward-looking statements that are subject to a
variety of risks and uncertainties. There are a number of important factors that
could cause the actual results to differ materially from those expressed in any
forward-looking statements made by the Company. These factors include, but are
not limited to: (i) the Company's ability to successfully complete product
research and development, including pre-clinical and clinical studies, and
commercialization; (ii) the Company's ability to obtain substantial additional
funding; (iii) the Company's ability to obtain required governmental approvals;
(iv) the Company's ability to attract manufacturing, sales, distribution and
marketing partners and other strategic alliances; and (v) the Company's ability
to develop and commercialize its products before its competitors.


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

T Cell Sciences' principal activity since its inception has been research and
product development conducted on its own behalf, as well as through joint
development programs with several pharmaceutical companies. The Company was
incorporated in the State of Delaware in December 1983.

A significant portion of the Company's revenue has consisted of payments by
others to fund sponsored research, milestone payments under joint development
agreements, payments for material produced for preclinical studies, and sales of
test kits and antibodies. Certain portions of the collaborative payments are
received in advance, recorded as deferred revenue and recognized when earned in
later periods.

Inflation and changing prices have not had a significant effect on continuing
operations and are not expected to have any in the near future.


OVERVIEW

The Company's technology platforms are based on its understanding of the ways in
which the body triggers its natural defense mechanisms. Product development
efforts focus on three therapeutic programs: developing compounds that inhibit
inappropriate complement activation, which is part of the body's immune defense
system; discovery and development of T cell activation regulators for the
prevention of transplant rejection and treatment of autoimmune diseases; and
development of a therapeutic vaccine for the management of atherosclerosis.

The Company's most advanced program is focused on complement inhibition and
includes clinical trials with its lead therapeutic compound, TP10. In October
1997, the Company released preliminary positive results demonstrating clinical
efficacy from its Phase I/II clinical trial for TP10 in patients undergoing lung
transplantation. Final trial results, including an analysis of the six-month
safety review which concluded in November 1997, are scheduled for presentation
in April 1998. In December 1997, the Company completed its Phase IIa clinical
trial for TP10 in patients with adult respiratory distress syndrome ("ARDS").
While trial results showed that patients receiving TP10 tended towards
improvement in respiratory performance and blood oxygenation, no definitive
claims of efficacy could be made due to the size and structure of the clinical
trial.

In addition to advancement of its lead program in the clinic, the Company
entered into an agreement with Novartis Pharma AG, Basel, Switzerland
("Novartis") in October 1997, relating to the development of TP10 for use in
xenotransplantation (animal organs into humans) and allotransplantation (human
to human). In exchange for granting Novartis a two-year option to license TP10
with exclusive worldwide marketing rights (except Japan) in the fields of
xenotransplantation and allotransplantation, the Company will receive annual
option fees and supplies of TP10 for clinical trials. If Novartis exercises its
option to license TP10, it will provide licensing fees, an equity investment and
milestone payments. The Company may also receive funding for research as well as
royalty payments on eventual product sales.

-13-


During 1997, the Company was awarded two Small Business Innovation Research
("SBIR") grants from the National Institutes of Health ("NIH") which will
contribute to the Company's program to develop a vaccine for the management of
atherosclerosis. A Phase I SBIR grant for $100,000 was received in February 1997
for the development of a novel DNA vaccine for the prevention and treatment of
atherosclerosis and a Phase II SBIR grant for $678,000 over two years was
awarded in September 1997 for the development of a novel transgenic rat model of
atherosclerosis. The Company was awarded its fourth SBIR grant from the NIH in
February 1998. Funding from the grant will contribute to the Company's program
for the development of a vaccine for the management of atherosclerosis.

In November 1997, the Company reached a settlement of the outstanding litigation
with its former landlord and the landlord's mortgagee. Under the settlement
agreement, the Company made a cash payment of $858,800 in November 1997 and
issued 1,500,000 shares of its common stock valued at $3,750,000 as of October
31, 1997. In addition, the Company signed two notes for $750,000 each due on
November 16, 1998 and November 15, 1999, respectively. The total settlement was
valued at $6,108,800 and is included as non-operating expense for the year ended
December 31, 1997.


RESULTS OF OPERATIONS

The Company reported a net loss of $13,108,000 or $0.52 per share for the year
ended December 31, 1997, compared with a net loss of $10,790,100 or $0.50 per
share for the year ended December 31, 1996 and a net loss of $8,257,900 or $0.47
per share for the year ended December 31, 1995. The net loss for the year ended
December 31, 1997 includes a charge to earnings of $6,108,800 for the settlement
of the Company's litigation with its former landlord and the landlord's
mortgagee. The net operating loss of $7,558,700 for the year ended December 31,
1997 includes total operating revenue of $1,192,100 offset by total operating
expense of $8,750,800. The net operating loss of $11,753,300 for the year ended
December 31, 1996 includes total operating revenue of $1,114,500 offset by total
operating expense of $12,867,800. The net operating loss for the year ended
December 31, 1995 of $11,862,500 includes total operating revenue of $3,963,100
offset by total operating expense of $15,825,600. Total operating expense for
1996 includes a charge to earnings of $1,751,600 for the write-off of certain
capitalized patent costs relating to the Company's T cell antigen receptor
program ("TCAR") and a $425,300 charge resulting from a severance agreement with
the Company's former President and Chief Executive Officer. Excluding these
charges from 1996, the net operating loss for 1997 decreased $2,017,700 or 21.1%
compared to 1996 and the net operating loss for 1996 decreased $2,286,100 or
19.3% compared to 1995.

In 1997, revenue from collaborative product development and distribution
agreements of $1,147,600 increased 94.1% from $591,200 in 1996 and decreased
28.7% from $1,608,700 in 1995. Revenue from collaborative product development
included milestone payments of $650,000 from the Company's collaborative partner
Astra AB ("Astra") for the year ended December 31, 1997 compared to $453,300 of
TCAR project funding from Astra for the same period last year. In December 1996,
the Company's collaborative agreement with Astra was amended, transferring
certain of the Company's rights to the TCAR technology to Astra who assumed sole
responsibility for further clinical development and commercialization. In May
1997, the Company completed the transfer of certain of its rights to the TCAR
technology to Astra and in June 1997, Astra received approval to initiate
clinical trials for one of the products derived from the TCAR technology
platform for the treatment of multiple sclerosis. In 1997, the Company was
awarded two SBIR grants from the NIH and one SBIR grant was received in 1996.
Revenue recognized from these grants was $247,600 in 1997 compared to $37,900 in
1996. The Company also recognized $250,000 in product development revenue from a
non-refundable option fee associated with an agreement granting Novartis the
right to license the Company's lead therapeutic compound, TP10, with exclusive
worldwide marketing rights (except Japan) in the fields of xenotransplantation
and allotransplantation. Included in product development revenue in 1996 is a
$100,000 non-refundable execution fee associated with an agreement granting
CytoTherapeutics, Inc. a worldwide, nonexclusive license to the Company's
technology and patent rights relating to Compliment Receptor 1 in return for a
series of milestone payments and royalties. In 1997 and 1996, the Company did
not have any distribution agreement revenue compared to $175,000 in 1995, which
represents a signing fee related to the distribution and marketing agreement for
TRAx products with Diamedix Corporation.

-14-


Product sales revenue decreased 91.5% to $44,500 for the year ended December 31,
1997 from $523,300 for the year ended December 31, 1996. Sales in 1997 included
TRAx product sales only compared to 1996 which included two months of research
product sales prior to the sale of the research products and operations of the
Company's wholly owned subsidiary, T Cell Diagnostics, Inc. ("TCD"), in March
1996, in addition to a full year of TRAx product sales. Product sales for 1996
decreased 77.8% from $2,354,400 in 1995 primarily due to the sale of the
research products and operations of TCD, which resulted in research product
sales for the first two months of the 1996 only compared to twelve months in
1995.

Cost of product sales amounted to $21,000, or 47.2% of product sales, $358,700,
or 68.5% of product sales and $1,879,400, or 79.8% of product sales for 1997,
1996 and 1995, respectively. The fluctuation in gross margin is the result of
several factors including: contract manufacturing costs for TRAx kits in 1997
compared to costs associated with manufacturing the Company's former research
product lines in 1996 and 1995, and costs associated with replacing the
manufacturing facility in 1995.

Research and development expense decreased 12.9% to $5,256,900 in 1997 compared
to $6,036,500 in 1996. The decrease is primarily due to a decrease in staff
costs combined with a reduction in costs associated with a Phase I/II clinical
trial of the Company's complement inhibitor, TP10, in patients undergoing lung
transplantation and a Phase IIa clinical trial of TP10 in ARDS patients.
Included in research and development expense for 1996 was two months of TCD
costs prior to the sale of the research products and operations of TCD in March
1996. Research and development expense decreased 24.6% to $6,036,500 in 1996
compared to $8,004,600 in 1995 primarily due to the sale of the research
products and operations of TCD in March 1996, combined with the full-year impact
of a restructuring program implemented in the third quarter of 1995, and was
partially offset by costs associated with the Phase I/II and Phase IIa clinical
trials initiated in 1996.

General and administrative expense for the year ended December 31, 1997 was
$3,375,500, which represents a decrease of 43.3% compared to 1996. In 1996,
general and administrative expense included a $425,300 charge resulting from the
severance agreement with the Company's former President and Chief Executive
Officer and a $1,751,600 write-off of certain capitalized patent costs relating
to the Company's TCAR technology. Excluding these charges from 1996, general and
administrative costs decreased 10.7% or $404,200 in 1997 compared to 1996. The
decrease is primarily due to lower legal fees in 1997 compared to 1996 which
resulted from the settlement of the litigation and reduced license fees caused
by the transfer of certain of its rights and responsibilities to Astra of the
Company's TCAR technology. General and administrative expense for the year ended
December 31, 1996, excluding the charge resulting from the severance agreement
with the Company's former President and Chief Executive Officer and the
write-off of certain capitalized patent costs relating to the Company's TCAR
technology, decreased 13.0% or $564,000 compared to $4,343,700 in 1995. The
decrease was primarily due to the sale of the research products and operations
of TCD in March 1996.

Marketing and sales costs decreased 81.1% in 1997 to $97,400 compared to 1996
and decreased 67.7% in 1996 to $516,000 compared to 1995. The decreases are
primarily due to the sale of the research products and operations of TCD to
Endogen in March 1996. Marketing and sales costs in 1997 and 1996 included costs
related to the TRAx product franchise which the Company continues to market in
conjunction with its distribution partner, Diamedix Corporation.

Non-operating expense of $5,549,300 in 1997 includes interest income of $577,300
and a charge to earnings of $6,108,800 from the settlement of the Company's
litigation with its former landlord and the landlord's mortgagee. Interest
income decreased $102,900 or 15.1% compared to interest income of $680,200 in
1996 primarily due to lower cash balances coupled with lower interest rates. In
1996, non-operating expense included a $283,000 gain recognized from the sale of
the research products and operations of TCD to Endogen in March 1996 and
interest income of $680,200. Other non-operating income of $3,604,600 in 1995,
included $2,900,000 received from the settlement of a lawsuit the Company
brought against its insurance carrier and interest income of $604,600.

-15-


LIQUIDITY AND CAPITAL RESOURCES

The Company's cash and cash equivalents at December 31, 1997 is $6,436,300
compared to $12,591,800 at December 31, 1996. Cash used in operations was
$7,695,400 in 1997, compared with $9,675,800 and $7,947,600 in 1996 and 1995,
respectively.

In November 1997, the Company reached a settlement of the litigation with its
former landlord and the landlord's mortgagee. As part of the settlement, the
Company agreed to pay $858,800 in cash on November 17, 1997 and issue a total of
1,500,000 shares of its common stock. In addition, the Company signed a note for
$750,000, due on November 16, 1998 secured by $750,000 cash and a note for
$750,000 due November 15, 1999 secured by 132,500 shares of common stock. The
total settlement, valued at $6,108,800, is comprised of the cash and notes
totaling $2,358,800 and common stock valued at $3,750,000 as of October 31,
1997. The common stock is subject to restrictions on transfer in accordance with
the settlement agreement. The settlement agreement also provides for certain
registration rights for the shares of common stock to become effective no later
than September 30, 1998. Upon such registration, however, the settlement
agreement limits the number of shares that may be sold over a given period of
time.

In March 1996, the Company received from Endogen a convertible subordinated note
in the principal amount of $2,003,000 in connection with the sale of the
research products and operations of TCD to Endogen. Pursuant to the terms of the
note, on February 10, 1997 the Company converted the $1,802,700 outstanding
principal balance of the note into shares of common stock of Endogen which the
Company subsequently sold. The realized gain on the stock sale was not
significant.

During 1994, the Company entered into an agreement providing the Company with
the right to lease up to $2,000,000 of equipment for up to a five-year term. The
lease arrangement contains certain restrictive covenants, determined at the end
of each fiscal quarter which, for the quarter ended September 30, 1995 included
a minimum cash, cash equivalents and short-term investments balance of
$10,000,000. At September 30, 1995 the Company's cash, cash equivalents and
short-term investment balance was below $10,000,000. As a result, in accordance
with the lease agreement, the Company pledged as collateral cash equal to the
amount outstanding on the lease which is to remain in a certificate of deposit
until the end of the lease, or as otherwise agreed by the lessor and the
Company. At December 31, 1997, the Company had $525,000 pledged as collateral
recorded as long-term restricted cash. In March 1996, the Company repaid
approximately $980,000 of the outstanding obligation under the lease in
conjunction with the sale of the research products and operations of its
subsidiary.

In March 1998, the Company completed a private placement of approximately
2,043,000 shares of common stock to institutional investors at a price of $1.90
per share. Net proceeds from the common stock issuance totaled approximately
$3,708,000. The Company believes that the private placement proceeds, together
with cash inflows from existing SBIR grants and collaborations, interest income
on invested funds and its current cash and cash equivalents, net of restricted
amounts, will be sufficient to meet estimated working capital requirements and
fund operations beyond December 31, 1998 and into the first half of 1999. The
working capital requirements of the Company are dependent on several factors
including, but not limited to, the costs associated with research
and development programs, preclinical and clinical studies and the scope of
collaborative arrangements. During 1998, the Company expects to take steps to
raise additional capital including, but not limited to, licensing of technology
programs with existing or new collaborative partners, possible business
combinations, or issuance of common stock via private placement and public
offering.

During 1997, the Financial Accounting Standards Board issued Statement of
Accounting Standards Nos. 128, "Earnings Per Share" ("SFAS 128"), 129,
"Disclosures about Information of Capital Structure" ("SFAS 129"), 130,
"Reporting Comprehensive Income" ("SFAS 130"), and 131, "Disclosure about
Segments of an Enterprise and Related Information" ("SFAS 131"). SFAS 128 and
SFAS 129 were effective for the year ended December 31, 1997 and were
appropriately adopted by the Company with no significant impact on the financial
condition or results of operations of the Company. SFAS 130 and SFAS 131 are
effective for the year ending December 31,

-16-


1998 and are not expected to have a significant impact on the Company's
financial condition or results of operations.

In January 1997, the Securities and Exchange Commission issued Financial
Reporting Release No. 48, which expands the disclosure requirements for certain
derivatives and other financial instruments. The Company does not utilize
derivative financial instruments. See Notes 1 and 2 to the Consolidated
Financials Statements for a description of the Company's use of other financial
instruments.

Sciences, Inc., and its subsidiary at December 31, 1997 and 1996, and the
results of their operations and their cash flows for each of the three years
ended December 31, 1997, in conformity with generally accepted accounting
principles. 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 of these statements in
accordance with generally accepted auditing standards which require that we plan

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1997, 1996 and 1995


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(A) Nature of Business

T Cell Sciences, Inc. (the "Company") is a biopharmaceutical company engaged in
the discovery and development of innovative drugs using novel applications of
immunology to prevent and treat cardiovascular, pulmonary and immune disorders.
The Company develops and commercializes products on a proprietary basis and in
collaboration with established pharmaceutical partners, including Novartis
Pharma AG, Astra AB and Yamanouchi Pharmaceutical Co., Ltd.

In March 1998, the Company completed a private placement of approximately
2,043,000 shares of common stock to institutional investors at a price of $1.90
per share. Net proceeds from the common stock issuance totaled approximately
$3,708,000. The Company believes that the private placement proceeds, together
with cash inflows from existing SBIR grants and collaborations, interest income
on invested funds and its current cash and cash equivalents, net of restricted
amounts, will be sufficient to meet estimated working capital requirements and
fund operations beyond December 31, 1998 and into the first half of 1999. The
working capital requirements of the Company are dependent on several factors
including, but not limited to, the costs associated with research
and development programs, preclinical and clinical studies and the scope of
collaborative arrangements. During 1998, the Company expects to take steps to
raise additional capital including, but not limited to, licensing of technology
programs with existing or new collaborative partners, possible business
combinations, or issuance of common stock via private placement and public
offering.

In March 1996, the Company sold substantially all of the assets of its
wholly-owned subsidiary, T Cell Diagnostics, Inc. ("TCD") while retaining all
rights to the TRAx(R) product franchise. The Company will continue to
commercialize the TRAx line of diagnostic products which are used in the
detection and monitoring of immune-related disorders.

(B) Basis of Presentation

The consolidated financial statements include the accounts of T Cell Sciences,
Inc. and its wholly owned subsidiary, T Cell Diagnostics, Inc. All intercompany
transactions have been eliminated.

(C) Cash Equivalents and Investments

The Company considers all highly liquid investments purchased with a maturity of
three months or less to be cash equivalents. Short-term investments are those
with maturities in excess of three months but less than one year. All cash
equivalents and short-term investments have been classified as available for
sale and are reported at fair market value with unrealized gains and losses
included in stockholders' equity.

The Company invests its nonoperating cash in debt instruments of financial
institutions, government entities and corporations, and mutual funds. The
Company has established guidelines relative to credit ratings, diversification
and maturities that maintain safety and liquidity.

(D) Fair Value of Financial Instruments

The Company enters into various types of financial instruments in the normal
course of business. Fair values for cash, cash equivalents, short-term
investments, accounts and notes receivable, accounts and notes payable and
accrued expenses approximate carrying value at December 31, 1997 and 1996, due
to the nature and the relatively short maturity of these instruments.

-24-


(E) Revenue Recognition

The Company has entered into various license and development agreements with
pharmaceutical and biotechnology companies. Revenue derived from such agreements
is recognized over the specified development period as research and development
or discovery activities are performed. Cash received in advance of activities
being performed is recorded as deferred revenue. Signing fees, received by the
Company for entering into license and development agreements are recognized when
received if the fees are nonrefundable and the Company has no obligations to
perform under the agreement. Revenues from product sales are recorded when the
product is shipped.

(F) Research and Development Costs

Research and development costs are expensed as incurred.

(G) Inventories

Inventories are stated at the lower of cost or market. Cost is determined using
the first-in, first-out (FIFO) method.

(H) Property and Equipment

Property and equipment is stated at cost and depreciated over the estimated
useful lives of the related assets using the straight-line method. Laboratory
equipment and office furniture and equipment are depreciated over a five year
period and computer equipment is depreciated over a three year period. Leasehold
improvements are amortized over the shorter of the estimated useful life or the
noncancelable term of the related lease.

(I) Licenses, Patents and Trademarks

Included in other assets are the costs of purchased licenses and certain costs
associated with patents and trademarks which are capitalized and amortized over
the shorter of the estimated useful lives or ten years using the straight-line
method. The Company periodically evaluates the recoverability of these assets in
accordance with Statement of Financial Accounting Standards No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of ("SFAS 121")."

(J) Loss Per Share

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"), which
changed the method of calculating earnings per share. SFAS 128, which the
Company adopted in the fourth quarter of 1997, requires the presentation of
"basic" earnings per share and "diluted" earnings per share. As a result of the
Company's net loss, both basic and diluted earnings per share are computed by
dividing the net loss available to common shareholders by the weighted average
number of shares of common stock outstanding.

(K) Stock Compensation

The Company's employee stock compensation plans are accounted for in accordance
with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees." The Company adopted the disclosure requirements of Statement of
Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based
Compensation" (see Note 7).

(L) Use of Estimates

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts and disclosures. Actual results
could differ from those estimates.

-25-


2. SHORT-TERM INVESTMENTS AND RESTRICTED CASH

The Company currently invests in only high quality, short-term investments which
are considered highly liquid and are available to support current operations. At
December 31, 1997 and 1996, the Company's investments met the definition of cash
equivalents and were recorded at cost, which approximated fair value in all
material respects.

At December 31, 1997, the Company had pledged as collateral $750,000 and
$525,000 which is recorded as current portion restricted cash and long-term
restricted cash, respectively. At December 31, 1996, the Company had pledged as
collateral $685,000 which is recorded as long-term restricted cash. Pursuant to
the terms of the settlement agreement between the Company and its former
landlord, the Company pledged as collateral $750,000 at December 31, 1997 (see
Note 13). The Company also has $525,000 and $685,000 pledged as collateral at
December 31, 1997 and 1996, respectively, in accordance with the terms of the
operating lease (see Note 3).


3. PROPERTY, EQUIPMENT AND LEASES

Property and equipment includes the following:



December 31, December 31,
1997 1996
--------------------------------------------


Laboratory Equipment $ 2,080,100 $ 2,055,000
Office Furniture and Equipment 767,800 751,500
Leasehold Improvements 255,000 219,500
-------------------------------------------
Property and Equipment, Total 3,102,900 3,026,000
Less Accumulated Depreciation and Amortization (2,738,400) (2,514,400)
-------------------------------------------
$ 364,500 $ 511,600
===========================================


Depreciation expense related to equipment and leasehold improvements was
approximately $224,000, $290,800 and $465,300 for the years ended December 31,
1997, 1996 and 1995, respectively.

In May 1996, the Company entered into a six-year lease for laboratory and office
space in Needham, Massachusetts. The lease replaced two-year lease and sublease
agreements entered into in March 1995 for the same location and increased the
amount of office and laboratory space available. In March 1996, the Company sold
certain property and equipment to Endogen as part of the sale of the research
products and operations of TCD. In addition, certain lease obligations of the
Company were assigned to Endogen in conjunction with the sale (see Note 14).

In August 1994, the Company entered into a lease agreement providing the Company
with the right to lease up to $2,000,000 of equipment for up to a five-year
term. The lease agreement contains certain restrictive covenants determined at
the end of each fiscal quarter which, for the quarter ended September 30, 1995,
included a minimum cash, cash equivalents and short-term investments balance of
$10,000,000. At September 30, 1995 the Company's cash and cash equivalents
balance was below $10,000,000. As a result, in accordance with the lease
agreement, the Company pledged cash as collateral to the lessor equal to the
amount outstanding on the lease which is to remain in a certificate of deposit
until the end of the lease or as otherwise agreed by the lessor and the Company.
The Company has recorded $525,000 and $685,000 as long-term restricted cash at
December 31, 1997 and 1996, respectively.

-26-

certain of its operations, the Company suspended internal funding of the
research and development of its T cell antigen receptor program pending
completion of negotiations to transfer certain of its patent and license rights
related to such technology to Astra AB. In June 1996, in accordance with SFAS
121, the Company evaluated and subsequently wrote off approximately $1,751,600
of capitalized patent costs relating to its T cell antigen receptor program
which is included in operating expense as general and administrative expense for
the year ended December 31, 1996.

==========================================================



The Company has provided a full valuation allowance for deferred tax assets as
management has concluded that it is more likely than not that the Company will
not recognize any benefits from its net deferred tax asset. The timing and
amount of future earnings will depend on numerous factors, including the
Company's future profitability. The Company will assess the need for a valuation
allowance as of each balance sheet date based on all available evidence.

At December 31, 1997, the Company has U.S. net operating loss carryforwards of
$67,224,700, U.S. capital loss carryforwards of $1,852,300, and U.S. tax credits
of $2,593,800 which expire at various dates from 1999 through 2010. Under the
Tax Reform Act of 1986, certain substantial changes in the Company's ownership
could result in an annual limitation on the amount of net operating loss
carryforwards, research and development tax credits, and capital loss
carryforwards which could be utilized.


7. STOCKHOLDERS' EQUITY

(A) Public and Private Stock Offerings

On August 26, 1996, the Company completed a public offering of 5,000,000 newly
issued shares of common stock. Net proceeds were approximately $10,069,000 after
deducting all associated expenses.

On November 7, 1995, the Company completed a private placement of 2,550,000
newly issued shares of common stock. Net proceeds were approximately $6,100,000
after deducting all associated expenses.

(B) Preferred Stock

At December 31, 1997 and 1996, the Company had authorized preferred stock
comprised of 1,163,102 shares of convertible Class B and 3,000,000 shares of
convertible Class C of which 350,000 shares has been designated as Class C-1
Junior Participating Cumulative, the terms of which are to be determined by the
Company's Board of Directors. There was no preferred stock outstanding at
December 31, 1997 and 1996.

(C) Stock Compensation and Employee Stock Purchase Plans

Stock Compensation

The Company's 1991 Stock Compensation Plan (the "1991 Plan"), which is an
amendment and restatement of the Company's 1985 Incentive Option Plan, permits
the granting of incentive stock options (intended to qualify as such under
Section 422A of the Internal Revenue Code of 1986, as amended), non-qualified
stock options, stock appreciation rights, performance share units, restricted
stock and for other awards of restricted stock in lieu of cash bonuses to
employees, consultants and outside directors.

-29-


The Plan allows for a maximum of 3,700,000 shares of common stock to be issued
prior to December 1, 2001. The Board of Directors determines the term of each
option, option price, number of shares for which each option is granted and the
rate at which each option vests. The term of each option cannot exceed ten years
(five years for options granted to holders of more than 10% of the voting stock
of the Company). The exercise price of stock options shall not be less than the
fair market value of the common stock at the date of grant (110% of fair market
value for options granted to holders of more than 10% of the voting stock of the
Company).

Employee Stock Purchase Plan

The 1994 Employee Stock Purchase Plan (the "1994 Plan") was adopted on June 30,
1994. All full time employees of the Company are eligible to participate in the
1994 Plan. A total of 150,000 shares are reserved for issuance under this plan.
An employee may participate voluntarily in any offering for up to 15% of their
compensation to purchase up to 500 shares per year and may withdraw from any
offering at any time before stock is purchased. Participation terminates
automatically upon termination of employment. 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.

A summary of stock option activity for the years ended December 31, 1997, 1996
and 1995 is as follows:

Fair Value Disclosures

Had compensation costs for the Company's stock compensation plans been
determined based on the fair value at the grant dates, consistent with SFAS 123,
the Company's net loss, and net loss per share for the years ending December 31,
1997, 1996 and 1995 would be as follows:



1997 1996 1995
-----------------------------------------------------------------------------------------------------

Net Loss:
As reported $13,108,000 $10,790,100 $8,257,900
Pro forma $13,514,100 $11,269,900 $8,471,400
Basic and Diluted Net Loss
Per Share:
As reported $0.52 $0.50 $0.47
Pro forma 0.54 0.52 0.48


The fair value of the option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following assumptions:



1997 1996 1995
-----------------------------------------------------------------------------------------------------

Expected dividend yield 0% 0% 0%
Expected stock price volatility 57% 51% 51%
Risk-free interest rate 5.5% - 6.4% 4.9% - 6.7% 5.4% - 7.5%
Expected option term 2.7 Years 2.6 Years 2.6 Years


Because the determination of the fair value of all options granted includes an
expected volatility factor in addition to the factors detailed in the table
above, and because additional option grants are expected to be made each year,
the above pro forma disclosures are not representative of pro forma effects of
reported net income for future years.

(D) Shareholder Rights Plan

On November 10, 1994, the Company's Board of Directors declared a dividend of
one preferred share purchase right for each share of common stock outstanding.
Each right entitles the holder to purchase from the Company one-one thousandth
of a share of Series C-1 Junior Participating Cumulative Preferred Stock (a
"Unit"), par value $.01 at a price of $16.00 per one-one thousandth of a share,
subject to certain adjustments. The Units are exercisable only if a person or a
group acquires 15% or more of the outstanding common stock of the Company or
commences a tender offer which would result in the ownership of 15% or more of
the Company's outstanding common stock. Once a Unit becomes exercisable, the
plan allows the Company's shareholders to purchase common stock at a substantial
discount. Unless earlier redeemed, the Units expire on November 10, 2004. The
Company is entitled to redeem the Units at $.01 per Unit subject to adjustment
for any stock split, stock dividend or similar transaction.

-31-


As of December 31, 1997, the Company has authorized the issuance of 350,000
shares of Series C-1 Junior Participating Cumulative Preferred Stock for use in
connection with the shareholder rights plan.

(E) Severance Agreement Charge

On May 29, 1996 the Company announced changes in its senior management. As part
of the reorganization, the Company recorded a $425,300 charge to earnings
resulting from a severance agreement with the Company's former President and
Chief Executive Officer. The charge included a $255,000 severance payment and a
non-cash charge of approximately $170,300 relating to the acceleration of
certain stock option vesting rights.


8. RESEARCH AND LICENSING AGREEMENTS

The Company has entered into licensing agreements with several universities and
research organizations. Under the terms of these agreements, the Company has
received licenses or options to license technology, certain patents or patent
applications. The Company made required payments of nonrefundable license fees
and royalties which amounted to approximately $65,000, $205,000 and $200,000 for
the years ended December 31, 1997, 1996 and 1995, respectively.


9. PRODUCT DEVELOPMENT AND DISTRIBUTION AGREEMENTS

The Company's product development revenues were received from contracts with
different organizations. Total revenue received by the Company in connection
with these contracts for the years ended December 31, 1997, 1996 and 1995 were
approximately $1,147,600, $591,200 and $1,608,700, respectively. A summary of
these contracts follows:

(A) Novartis Pharma AG

In October 1997, the Company entered into an option agreement with Novartis
Pharma AG ("Novartis"), a worldwide pharmaceutical company headquartered in
Basel, Switzerland, relating to the development of TP10 for use in
xenotransplantation (animal organs into humans) and allotransplantation (human
to human). The agreement granted Novartis a two-year option to license TP10 with
exclusive worldwide marketing rights (except Japan) in the fields of
xenotransplantation and allotransplantation. In exchange for granting the
two-year option, the Company will receive annual option fees and supplies of
clinical grade TP10 with a combined value of up to $5 million. Should Novartis
exercise its option to license TP10 and continue development within the fields
of xenotransplantation and allotransplantation, it will provide equity to the
Company in the form of investment, licensing fees and milestone payments based
upon attainment of certain development and regulatory goals. The Company may
also receive from Novartis funding for research as well as royalty payments on
eventual products sales.

Under the terms of the agreement Novartis paid the Company a non-refundable
option fee related to the first option period which commenced in October 1997.
During the option period, Novartis is granted sole access to the technology for
use in xenotransplantation and allotransplantation. The Company is recording the
option fee as revenue over the one year option period.

(B) Astra AB

In January 1992, the Company entered into a product development and distribution
agreement with Astra AB ("Astra"), a worldwide pharmaceutical company
headquartered in Sodertalje, Sweden, for the joint development and marketing of
therapeutic products using T Cell Sciences' proprietary T cell antigen receptor
("TCAR") technology. The products developed exclusively and jointly with Astra
were monoclonal antibodies and protein-

-32-



derived immunomodulators that may have efficacy in treating autoimmune diseases
such as multiple sclerosis, Crohn's disease, and rheumatoid arthritis.

In June 1996, the Company suspended further internal funding of the research and
development of the TCAR program. In December 1996, the Company further amended
its agreement with Astra to transfer certain of its rights to the TCAR
technology to Astra in addition to sole responsibility for further development
and commercialization of the TCAR technology. Under the amended agreement, the
Company received an initial signing fee of $100,000 and could receive future
milestone and royalty payments upon Astra's successful development and
commercialization of the TCAR technology.

The Company recognized revenue from milestone payments in 1997 of $650,000. The
Company recognized TCAR funding revenue of $453,400 in 1996 and $1,433,700 in
1995 which included $181,600 and $318,400, respectively, from the reduction of
the collaborator advance liability. The funds were advanced from Astra for the
expansion of additional space dedicated to joint TCAR product research.

(C) CytoTherapeutics

In April 1996, the Company licensed portions of its patent and technology rights
regarding Complement Receptor 1 ("CR1") to CytoTherapeutics, Inc. for use in
CytoTherapeutics' cell-based products for the delivery of therapeutic substances
to the central nervous system. Under the agreement, the Company granted
non-exclusive rights for the use of CR1 in any encapsulated-cell product. The
license does not include rights to use CR1 for therapeutic effects. In 1996, the
Company received a non-refundable $100,000 signing fee and may receive
additional milestone payments and royalty payments from commercialized products
resulting from the license.

(D) Diamedix Corporation

In December 1995, the Company received a $175,000 signing fee associated with an
exclusive distribution agreement it entered into with Diamedix Corporation to
market TRAx CD4 and TRAx CD8 microtiter plate diagnostic kits to clinical
diagnostic laboratories in the United States. The Company retained the rights to
sell these kits to certain research laboratories and pharmaceutical companies.
The agreement was modified in 1997 from an exclusive agreement to a
non-exclusive agreement.

(E) SmithKline Beecham, p.l.c

In 1989, the Company signed an exclusive development and distribution contract
for TP10 (sCR1) with SmithKline Beecham. The Company entered into a new
agreement in October 1994 with SmithKline Beecham, which superseded the original
agreement. Under the new agreement, the Company regained exclusive rights to
sCR1 in North America, including clinical development and marketing rights and
SmithKline Beecham was granted an option for clinical development and marketing
of injectable sCR1 outside of North America. The Company and SmithKline Beecham
mutually agreed to terminate the October agreement in February 1995, returning
all rights to the Company with no future financial obligations to either party.

Under section 401(k) of the Internal Revenue Code of 1986, as amended, the Board
of Directors adopted, effective May 1990, a tax-qualified deferred compensation
plan for employees of the Company. Participants may make tax deferred
contributions up to 15%, or $9,500, of their total salary in 1997. The Company
may, at its discretion, make contributions to the plan each year matching up to
1% of the participant's total annual salary. Company contributions amounted to
$20,600, $33,000 and $39,000 for the years ended December 31, 1997, 1996 and

13. LITIGATION

In December 1994, the Company filed a lawsuit in the Superior Court of
Massachusetts against the landlord of its former Cambridge, Massachusetts
headquarters to recover the damages incurred by the Company resulting from the
evacuation of the building due to air quality problems, which caused skin and
respiratory irritation to a significant number of employees. The landlord
defendant filed counterclaims, alleging the Company breached its lease
obligations. The court ordered a limited trial between the Company and the
landlord on certain factual issues which began on November 20, 1996. Closing
arguments for the limited trial were heard on January 13, 1997. In a separate
lawsuit, the landlord's mortgagee filed claims against the Company for payment
of the same rent alleged to be owed. A motion for summary judgment filed by the
bank was denied by the court. In August 1997, the Superior Court of
Massachusetts entered findings of fact and conclusions of law on the limited
trial of the Company's lawsuit against the landlord. In its findings, the Court
concluded that the Company had not proved, as alleged by the Company, that any
fireproofing fibers contaminated the Company's space, the Company's space was

-34-


not uninhabitable because of contamination from fireproofing fibers and the
Company was not justified in terminating its lease on the grounds that its
office and laboratories were uninhabitable. In November 1997, the Company
reached a settlement of the litigation with its former landlord and the
landlord's mortgagee. The Company agreed to pay $858,800 in cash on November 17,
1997 and issue a total of 1,500,000 shares of its common stock. In addition, the
Company signed a note for $750,000 payable on November 16, 1998 secured by
$750,000 cash collateral and a note for $750,000 due November 15, 1999, secured
by 132,500 shares of common stock. The total settlement, valued at $6,108,800,
is comprised of the cash and notes totaling $2,358,800 and common stock valued
at $3,750,000 as of October 31, 1997 and is included in non-operating expense
for the year ended December 31, 1997. The common stock issued is subject to
restrictions on transfer per the settlement agreement. The settlement agreement
also provides for certain registration rights for the shares of common stock to
become effective no later than September 30, 1998. Upon such registration,
however, the settlement agreement limits the number of shares that may be sold
over a given period of time.

14. SALE OF PORTION OF DIAGNOSTIC BUSINESS

On March 5, 1996 the Company sold to Endogen, Inc. the research products and
operations of TCD for a purchase price of approximately $2,880,000, while
retaining the TRAx diagnostic product franchise. The consideration for this sale
to Endogen was paid in the form of a convertible subordinated note receivable
(the "Convertible Note") in the principal amount of $2,003,000 and a combination
of cash and a short-term note used to repay approximately $980,000 of
obligations under the Company's operating lease. On February 10, 1997, the
Company converted the outstanding principal balance, or $1,803,000, of the
Convertible Note into shares of Endogen commons stock which it subsequently
sold. Additionally, the Company may receive a royalty on certain of Endogen's
sales of research products.
