OVERVIEW/BUSINESS STRATEGY

  The Liposome Company, Inc. (the "Company") is a leading biotechnology company
engaged in the discovery, development and, recently, the commercialization of
proprietary lipid and liposome-based pharmaceuticals for the treatment,
prevention and diagnosis of inadequately treated, life-threatening illnesses.
The Company is currently launching its first product, amphotericin B lipid
complex (ABLC (R) or, in Europe, Abelcet TM), which has been approved for
marketing for certain indications in the United Kingdom and is the subject of
marketing application filings in eighteen other countries. The Company expects
to file a new drug application ("NDA") for ABLC (R) in the United States during
1995. In addition to ABLC (R)/Abelcet TM, the Company's other lead products are
TLC D-99 and TLC C-53. TLC D-99, liposomal doxorubicin, is being developed in
conjunction with Pfizer Inc. ("Pfizer") primarily as a first line treatment of
metastatic breast cancer, and is undergoing Phase III clinical testing in the
United States. The Company has completed a Phase II clinical trial for TLC C-53,
liposomal prostaglandin E1, for the treatment of acute respiratory distress
syndrome ("ARDS") and is preparing a protocol for a pivotal clinical trial of
TLC C-53 for ARDS. In January, 1995, the Company commenced a Phase II clinical
trial of TLC C-53 for the treatment of acute myocardial infarction ("AMI"), or
heart attack.

  ABLC (R)/Abelcet TM, amphotericin B lipid complex, is for the treatment of
systemic fungal infections, primarily in immunocompromised patients such as
cancer chemotherapy patients, organ and bone marrow transplant recipients and
people with AIDS. In February, 1995, the Company received approval from the
Medicines Control Agency of the United Kingdom to market Abelcet TM as a first
line treatment of cryptococcal meningitis and systemic cryptococcosis in
patients with AIDS and for the treatment of severe systemic fungal infections in
patients who have not responded to conventional amphotericin B, or to other
systemic antifungal agents, or who have renal impairment or other
contraindications to conventional amphotericin B. Over 1,300 patients worldwide
had been treated with ABLC (R)/AbelcetTM through December, 1994. The Company
expects to file its first NDA, for ABLC (R), for the second line treatment of
aspergillosis (a severe systemic fungal infection) in the United States during
1995. There can be no assurance that any NDA filing by the Company will
ultimately be approved by the U.S. Food and Drug Administration ("FDA"). 

  TLC D-99, liposomal doxorubicin, is targeted for the treatment of a variety of
solid tumors, most importantly metastatic breast cancer. TLC D-99 is being
jointly developed by the Company and Pfizer pursuant to an agreement entered
into in 1990. The Company has completed three Phase II clinical trials testing
TLC D-99 as a first line treatment of metastatic breast cancer. Two Phase III
clinical trials commenced in December, 1994. In November, 1994, researchers from
the M.D. Anderson Cancer Center presented results of one of the Phase II
studies, where TLC D-99 was given in combination with cyclophosphamide and 5-
fluorouracil to metastatic breast cancer patients. The researchers reported
that, of the 41 patients in the trial, 29 were evaluable at that time. Of those
29 patients, there was an overall response rate of 69% (20 patients). Of these,
18 patients demonstrated a partial response (defined to include a reduction in
tumor size of 50% or more), and two patients demonstrated a complete response.

  TLC C-53, liposomal prostaglandin E1 ("PGE1"), is for the treatment of severe
acute inflammatory and vaso-occlusive conditions, including ARDS and AMI.
Preclinical trials have shown favorable results with TLC C-53 in models of AMI
and in models of systemic inflammatory response syndrome ("SIRS"), including
endotoxemia and ARDS. The Company has completed a Phase II study of TLC C-53 for
the treatment of ARDS and plans to initiate a pivotal study 

                                       4
<PAGE>
 
following discussions with the FDA. In January, 1995, the Company commenced a
Phase II clinical trial of TLC C-53 versus a placebo, each in conjunction with
t-PA, heparin and aspirin, for the treatment of heart attacks.

  The Company and Schering AG, Berlin ("Schering AG") entered into a
collaborative research and development agreement with respect to TLC I-16, a
non-ionic contrast agent for use in connection with CT scanning of the liver.
TLC I-16 is currently in preclinical development. The Company also has a
continuing discovery research program which concentrates primarily on the
treatment of cancer and inflammatory conditions.

  TECHNOLOGY

  The Company's products are based on its proprietary technology which employs
liposomes or lipid complexes as either a vehicle to deliver an active
therapeutic ingredient or as an active component of a drug. Liposomes are
microscopic man-made spheres composed of lipids that can be engineered to entrap
drugs or other biologically active molecules. In many cases, liposomal
pharmaceuticals can provide better efficacy and less toxicity than might
otherwise result from alternative therapies. In addition, the Company believes
that it is developing the first product, TLC C-53, in which liposomes comprise
active components of a pharmaceutical. It is anticipated that the Company's
products will be administered through intravenous injection.


  PRODUCTS IN CLINICAL TRIALS

  The Company has three products in various stages of human clinical trials for
multiple indications: ABLC(R)/AbelcetTM, TLC D-99 and TLC C-53.


  ABLC (R) (AbelcetTM in Europe)--Amphotericin B Lipid Complex
  ------------------------------------------------------------

  Systemic fungal infections are a major threat to those patients whose immune
systems are compromised, such as cancer chemotherapy patients, organ and bone
marrow transplant recipients and people with AIDS. The Company is developing
ABLC(R) as a treatment for these fungal infections. Over 1,300 patients
worldwide were treated with ABLC(R) in comparative and open-label clinical
trials as well as in emergency use protocols through December, 1994.

  Amphotericin B is a broad spectrum polyene antifungal agent, which has been
marketed for many years as a treatment for many systemic fungal infections,
including candidiasis, cryptococcosis, aspergillosis and other yeast or mold
infections. However, the utility of amphotericin B has been limited by its
propensity to cause serious side effects, particularly to the kidney. The
Company is developing ABLC(R), which consists of amphotericin B in a lipid
complex and is designed to reduce the risk of toxicities associated with
amphotericin B while maintaining at least equivalent efficacy.

  In June, 1994, the Company commenced two Phase III clinical trials for ABLC(R)
in the U.S. The first trial is testing ABLC(R) as a treatment for patients with
aspergillosis who are either refractory to or intolerant of conventional
amphotericin B or who have renal impairment that precludes treatment with
amphotericin B. The second is a randomized trial comparing ABLC(R) to
conventional amphotericin B in the empiric treatment of presumed fungal
infections in neutropenic patients.

  In October, 1994, investigators from the National Cancer Institute ("NCI"),
the M.D. Anderson Cancer Center, the Children's National Medical Center and the
H. Lee Moffitt Cancer Center, in a poster presentation at the 34th Interscience
Conference on Antimicrobial Agents and Chemotherapy, showed encouraging results
in patients with systemic fungal infections receiving ABLC(R) who previously did
not respond to, or who were intolerant of, existing antifungal therapy. In
addition, patients who had suffered nephrotoxicity resulting from prior
treatment with amphotericin B or who had preexisting renal impairment showed a
statistically significant improvement in kidney function when placed on ABLC(R).
The researchers concluded that ABLC(R) provided effective therapy in patients
with invasive mycoses unresponsive to or intolerant of previous antifungal
therapy, that ABLC(R) was well tolerated and that ABLC(R) was not associated
with dose-limiting nephrotoxicity.

  Since December, 1993, the Company has filed applications to market
ABLC(R)/Abelcet TM in nineteen countries. In February, 1995, the Company
received approval to market amphotericin B lipid complex under the trademark
AbelcetTM from the Medicines Control Agency of the United Kingdom. The
indications for which AbelcetTM was approved were as a first line treatment of

                                       7
<PAGE>
 
cryptococcal meningitis and systemic cryptococcosis in patients with AIDS and
for the treatment of severe systemic fungal infections in patients who have not
responded to conventional amphotericin B or to other systemic antifungal agents
or who have renal impairment or other contraindications to conventional
amphotericin B. The Company believes it may receive marketing approvals in
additional countries during 1995 and in later years. In one of the foreign
countries in which a marketing application for Abelcet TM has been filed, the
Company has received a preliminary indication that the application may not be
approved or that additional studies may be required as a condition of approval.


  The Company expects to file an NDA for ABLC (R) for the second line treatment
of aspergillosis in the United States during 1995. The Company has not yet
submitted an NDA in the United States, and no assurance can be given that with
respect to the Company's NDA for ABLC(R) that it will be accepted for
consideration, that it will be promptly reviewed, that the FDA will find the
data submitted adequate or that it will ultimately be approved.

  The Company owns worldwide rights to manufacture and market ABLC(R). In 1985,
the Company entered into a licensing and development agreement for ABLC(R) with
the E.R. Squibb & Sons Company, now BMS. As of January 1, 1993, the Company
reacquired these rights from BMS and assumed all financial responsibility for
the development of ABLC(R). The Company has agreed to pay BMS a royalty on
worldwide sales of ABLC(R)/AbelcetTM. The Company has also entered into a supply
agreement with BMS for amphotericin B raw material, but is free to access
alternate suppliers of such raw material, subject to regulatory constraints.


  TLC D-99
  --------

  The Company and Pfizer are jointly developing TLC D-99, a liposomal
doxorubicin, for the treatment of a variety of solid tumors. The primary
emphasis of the program has been to develop the drug as a first line treatment
of metastatic breast cancer. Over 400 patients were enrolled in TLC D-99
clinical trials through December, 1994.

  One of the most widely-used chemotherapeutic drugs is doxorubicin, which is
used in the treatment of many solid tumors, leukemias and lymphomas.
Doxorubicin, in addition to the acute toxicities typical of chemotherapeutic
drugs, can cause irreversible cardiac damage which is often the cumulative dose-
limiting factor for anthracycline chemotherapeutic agents like doxorubicin.
Virtually all anticancer drugs in typical doses can cause side effects such as
emesis (vomiting), alopecia (hair loss), mucositis (inflammation of the mucous
membranes) and myelosuppression (depletion of blood cells). The individual
maximum dosage given to a patient is limited by these and other toxic side
effects. One of the serious toxicities associated with doxorubicin is the
necrosis (open sores and tissue damage) that will occur when free doxorubicin is
accidentally injected into subcutaneous tissue rather than the vein (an
extravasation event). During Phase I trials with TLC D-99, three episodes of
extravasation took place, and no necrosis was observed.

  Preclinical studies indicate that, as compared to free doxorubicin, TLC D-99
has greatly reduced toxicity, including cardiotoxicity and mucositis. In a
preclinical model, TLC D-99 was shown to deliver, at comparable doses, two to
three times as much drug to the site of the tumor as compared to free
doxorubicin. In addition, preclinical studies in standard tumor models comparing
the use of TLC D-99 and free doxorubicin to treat leukemia and several solid
tumors show a better tumor response and an increase in the survival period of
the test animals receiving TLC D-99 as compared to free doxorubicin.

                                       8
<PAGE>
 
  The Company conducted Phase I human clinical testing of 38 patients at Roswell
Park Memorial Institute, in Buffalo, New York. In this trial, TLC D-99 was less
acutely toxic to the patients than would be expected with free doxorubicin at
comparable doses.

  In December, 1992 and May, 1993, the Company completed patient accruals for
two Phase II trials in patients with metastatic breast cancer; one was conducted
at four hospitals associated with McGill University Hospital in Montreal, Canada
and one was conducted at multiple sites in the United States. Data from these
trials is being compiled and evaluated. In November, 1994, researchers from the
M.D. Anderson Cancer Center presented results of a third Phase II study of TLC
D-99 given in combination with cyclophosphamide, an anti-neoplastic agent, and
5-fluorouracil to metastatic breast cancer patients. The researchers reported
that, of the 41 patients in the trial, 29 were evaluable at that time. Of those
29 patients, there was an overall response rate of 69% (20 patients). Of these,
18 patients demonstrated a partial response (defined to include a reduction in
tumor size of 50% or more), and two patients demonstrated a complete response.
The researchers also concluded that the encapsulation of doxorubicin appears to
permit higher cumulative doses than would be expected with conventional
doxorubicin because of the diminished cardiotoxicity.

  In December, 1994, two Phase III trials were commenced by Pfizer to test TLC
D-99 as a first line treatment for patients with metastatic breast cancer. One
trial compares TLC D-99 with conventional doxorubicin while the other compares a
combination of TLC D-99 and cyclophosphamide, with doxorubicin and
cyclophosphamide. The objective of each study is to show that TLC D-99, alone or
in combination with cyclophosphamide, is as effective as conventional
doxorubicin alone or in combination with cyclophosphamide, but that TLC D-99 is
significantly safer, particularly with regard to cardiotoxicity. Each trial is
expected to be conducted at twenty or more sites.

  The Company and Pfizer are also conducting trials using very high doses of TLC
D-99 in combination with granulocyte colony--stimulating factor ("G-CSF"). As
part of this program, the Company and the NCI have been conducting a Phase I
trial at Dana-Farber Cancer Institute, in Boston, Massachusetts to test the
safety and efficacy of increasing doses of TLC D-99 in combination with G-CSF.
Preliminary results of this study were presented at the Seventh World Conference
on Lung Cancer in June, 1994. Although the trial was primarily designed to test
the safety of TLC D-99 in high doses, partial clinical responses (tumor
reduction exceeding 50 percent) were recorded in three of twelve patients with
non-small cell lung cancer, two of two patients with mesothelioma and three of
four patients with small cell lung cancer. Non-small cell lung cancer and
mesothelioma historically have a very low response rate to chemotherapy.

  In 1994, the Company commenced a Phase II clinical trial to test high doses of
TLC D-99 as a treatment for metastatic breast cancer. The trial objective is to
demonstrate superior efficacy and acceptable safety of very high doses of TLC D-
99 as compared to what could be expected with conventional doxorubicin. Patients
are currently being accrued in this trial. If results of this trial are
positive, the Company expects to conduct a Phase III clinical trial of high
doses of TLC D-99 to treat metastatic breast cancer. Additionally, a Phase II
clinical trial to test TLC D-99 as a treatment for Kaposi's Sarcoma is ongoing.

  In November, 1990, the Company entered into a development and license
agreement for TLC D-99 with Pfizer. Pfizer is funding the development and
clinical trials of the product. The Company received a payment upon signing the
agreement with Pfizer and is entitled to be reimbursed quarterly in advance of
expenditures, based on an agreed-upon annual budget, for virtually all of its
costs to be incurred in connection with product development and clinical
testing, to receive payments upon reaching certain milestones, and to receive
royalty payments with respect to product sales. The agreement has no fixed term
and is terminable at any time upon notice by Pfizer, in which event 

                                       9
<PAGE>
 
Pfizer would be responsible for reimbursement of the Company's expenses for up
to a six-month period following termination and all rights to the product would
return to the Company. The Company has all rights to market TLC D-99 in Japan.



  TLC C-53
  --------

  The Company is developing TLC C-53, liposomal PGE/1/, for the treatment of a
variety of severe acute inflammatory conditions and vaso-occlusive diseases. TLC
C-53 is the first product known to the Company in which liposomes comprise
active components of a pharmaceutical.

  Anti-inflammatory Applications.   Many disease conditions are believed to be
the result of a complex cascade of events leading to the uncontrolled activation
of certain cells in the body: neutrophils, platelets and endothelial cells.
These cells, once activated, adhere to each other and to certain other cells,
thus perpetuating, and in some instances leading to, a pathological enhancement
of the inflammatory response.

  When the body receives an insult, such as infection, massive trauma or heart
attack, cells can release into the blood a variety of chemical agents or
mediators including interleukin-1 ("IL-1"), tumor necrosis factor ("TNF"), and
others. When any of these mediators encounters certain types of cells in the
body such as neutrophils (cells that circulate in the bloodstream) or
endothelial cells (cells that form the lining of the blood vessels), these cells
may become activated. When neutrophils and endothelial cells are activated they
can then adhere to each other as part of the normal inflammatory response. In
some patients, the normal process of activation continues unchecked and an
inflammatory condition known as SIRS, including ARDS and sepsis, may result.

  SIRS is an often fatal condition that includes subsets of conditions such as
ARDS and sepsis. It stems from a variety of severe insults including trauma,
burns, aspiration and hyperoxia. Clinically, patients exhibit abnormalities in
body temperature, heart and respiratory rate and white blood cell count. The
condition is often associated with development of failure of several body
organs. In ARDS the organ which fails is the lung. Clinically, white opacities
are seen in the lung fields on radiological examination, reflecting the
congestion of the lung air spaces with fluid that has leaked through capillaries
that had been damaged by mediators of inflammation released by the activated
neutrophils. Forty to sixty percent of the approximately 150,000 patients in the
United States annually afflicted with ARDS die because the lungs become so full
of fluid that oxygen can no longer be transported with efficiency into the
blood. There is currently no satisfactory therapy for ARDS.

  Sepsis is the systemic response to infection. In sepsis, a somewhat similar if
not identical process of abnormal activation of neutrophils and other cells
which circulate in the bloodstream occurs. This process is responsible for the
failure of a number of body organs including the lungs, the kidneys, the liver
and the brain, often resulting in death.

  TLC C-53 appears to function as a unique "universal off-switch" that not only
prevents neutrophils from being activated by IL-1, TNF, and other factors, but
also may deactivate these cells even after they have been activated. By
inhibiting neutrophils in this way, TLC C-53 is believed to prevent abnormal
cellular adhesion which in turn prevents the release of the mediators of
inflammation, such as oxygen free radicals and lysosomal enzymes.

  In 1990, the Company commenced preclinical development of TLC C-53, including
efficacy tests with TLC C-53 in preclinical models of ARDS and AMI. In two
animal models of ARDS tested at The Webb-Waring Lung Institute, one of the
leading ARDS research centers in the United States, it was shown that TLC

                                       10
<PAGE>
 
C-53 could significantly prevent the leakage of fluid into the lung. In 1992,
the Company filed an IND with the FDA and started Phase I safety trials in
healthy volunteers in the United States and in Europe.

  During 1994, the Company conducted a Phase II trial of TLC C-53 as a treatment
for ARDS. Results of the 25 patient randomized, placebo controlled trial were
presented at the Society of Critical Care Medicine's 24th Educational and
Scientific Symposium in February, 1995. The investigators concluded that in
patients with ARDS, TLC C-53 was associated with statistically significant
improvement in oxygenation (the ability of the lungs to transmit oxygen into the
bloodstream) at three days, increased lung compliance (an indirect measure of
lung function), and decreased dependency of patients on mechanical ventilation.
The investigators also concluded that TLC C-53 was well tolerated.

  Cardiovascular Applications.   The factors discussed above that activate
neutrophils and endothelial cells also activate platelets, a type of blood cell
that, among other functions, plays a key role in blood clotting. Platelets are
also activated when they contact the cells that line the arteries, which can
often occur during coronary angioplasty. Once activated, platelets adhere to
each other (called aggregation) as well as to endothelial cells and the
extracellular matrix. In some patients, myocardial wall damage may occur after
the coronary arteries have been opened by the infusion of t-PA. This so-called
"reperfusion injury" is believed to be initiated by activation of neutrophils.

  TLC C-53, in addition to inhibiting neutrophils, is believed to inhibit
platelet aggregation. This combination of drug effect may hold promise for more
patients with AMI to achieve complete patency (reopening of the coronary
arteries) following treatment with t-PA and may also allow a faster clot to
lysis time. It also holds the potential for reducing reperfusion injury and
subsequent cardiac damage.

  In November, 1994, the Journal of the American College of Cardiology published
results from preclinical studies of TLC C-53 conducted by Dr. Richard Smalling,
Professor and Co-Director of the University of Texas Medical School's Division
of Cardiology. In a canine model of heart attack, Dr. Smalling showed that
treatment with TLC C-53 just prior to administration of the clot-dissolving
agents streptokinase and heparin, resulted in faster reopening of the blocked
blood vessels that caused the attack. Additionally, the arteries opened more
fully, blood flow to heart tissue was improved, and there was less damage to the
heart when TLC C-53 was given, compared with placebo.

  At year-end 1994, the Company started a Phase II randomized, placebo
controlled trial to evaluate TLC C-53 as an adjunct to t-PA in the treatment of
heart attacks. In the trial, patients will receive either TLC C-53 or a placebo
in addition to t-PA, heparin and aspirin. The first patient was enrolled in
January, 1995 at the Hermann Hospital and the Texas Medical Center in Houston,
Texas.


 OTHER PRODUCTS UNDER DEVELOPMENT

  The Company is also developing other liposome based products that are in
earlier stages of development. These include:


  TLC I-16
  --------

  The Company has conducted basic research on an innovative technology for
making liposomes called interdigitation fusion. The first product produced by
this new process is a liposome-encapsulated non-ionic iodine-based contrast
agent, TLC I-16. The Company is developing TLC I-16 with Schering AG. TLC I-16
contains a high concentration of the contrast agent, allowing it to be

                                       11
<PAGE>
 
effectively used for CT scanning of the liver and may provide a more sensitive
technique for the detection of tumor metastases. Preclinical studies conducted
at Brigham and Women's Hospital in Boston have shown that the Company's product
can permit greatly enhanced CT images of the liver and spleen over longer
periods of time.

  In December, 1990, the Company entered into an agreement with Schering AG (the
"Schering Agreement") for the development, testing, manufacturing, and marketing
of TLC I-16. The Schering Agreement, as amended, provides for the co-development
of TLC I-16 by the Company and Schering AG. It also provides that, upon
commercialization, the Company is to manufacture and Schering AG is to market
and sell TLC I-16 worldwide. Schering AG will also provide certain development
funding, make payments upon the achievement of certain milestones and pay
royalties on worldwide product sales.

  TLC C-54
  --------

  The Company is developing TLC C-54, a liposomal PGE1 distinct and different
from TLC C-53, for use in the treatment of auto-immune diseases such as
rheumatoid arthritis and systemic lupus erythematosus. TLC C-54 is currently
undergoing preclinical testing.


  TLC A-60
  --------

  TLC A-60 is a unique, patented liposomal vaccine adjuvant designed to boost
the protective effect of vaccines against various diseases. In January, 1992,
Wyeth-Ayerst and the Company signed an agreement under which Wyeth-Ayerst began
the development of a liposomal influenza vaccine with TLC A-60. During 1994,
Wyeth-Ayerst conducted Phase I and Phase II clinical trials of the vaccine. In
March, 1995, Wyeth-Ayerst advised the Company that it intends to return its
rights to TLC A-60 to the Company. The Company has not yet reviewed the results
from Wyeth-Ayerst's Phase II trials, but, based on its current understanding,
will consider seeking another corporate sponsor to develop TLC A-60 as an
adjuvant for an influenza vaccine. No assurance can be given that such a
corporate sponsor relationship will be entered into.


  RESEARCH PROGRAMS

  The Company is conducting research in the areas of cancer and inflammation and
has an in vitro and in vivo screening facility, including cell lines and a mouse
xenograft capability to support its cancer research. Its inflammation research
is directed towards the discovery and development of new and improved anti-
inflammatory agents. The Company is also conducting research on liposomal
prostaglandins for other indications.


MANUFACTURING

  The Company has constructed and validated a multiproduct manufacturing
facility at its Princeton site. This facility has been designed to have the
capacity to manufacture supplies for the ABLC (R), TLC D-99, and TLC C-53
clinical trial programs and for future products using similar manufacturing
processes. The Company also expects to use this facility to manufacture initial
commercial supplies of ABLC (R). This facility has been approved by the
Medicines Control Agency of the United Kingdom for the manufacture of Abelcet TM
for sale in that country. This approval is also acceptable to regulatory
authorities in other European Union ("EU") countries. However, approval by the
FDA of the manufacture of products in the Princeton facility will be required
prior to commercial sales in the United States.

  In July, 1992, the Company purchased a manufacturing facility in Indianapolis,
Indiana, for the commercial production of certain of the Company's products and
has begun the renovation of this facility. The 

                                       12
<PAGE>
 
refitting of this facility and the purchase, installation and validation of
substantial additional processing equipment at an aggregate cost of
approximately $11,000,000 to $13,000,000 will be necessary before any production
can commence. Approval by the FDA in the United States, or regulators in other
countries in which sales are to be made, of the manufacture of products in the
Indianapolis facility will be required prior to commercial sales.

  The Company also has a validated, sterile liposome manufacturing pilot plant
at its headquarters. The Company believes that its current facilities and staff
are adequate for the manufacture of preclinical and clinical supplies of its
products, and for the production of quantities of Abelcet TM to satisfy initial
commercial demand, but may not be capable of producing quantities of product
sufficient to satisfy demand when ABLC (R) is fully commercialized.

  The Company has several patented or proprietary processes for the manufacture,
handling, loading and drying of liposomes.


MARKETING STRATEGY

  The Company has established an office in London, England with a small sales
force which the Company believes is appropriate for the marketing and sale of
AbelcetTM in the United Kingdom. The Company may collaborate with third parties
in the marketing, sales and distribution of its products in some or all of the
European markets. The Company intends to develop its own sales and marketing
capabilities in the United States to market ABLC (R) and certain other of the
Company's products if and when approved by the FDA.


HUMAN RESOURCES

  At December 31, 1994, the Company had 217 full-time employees, 30 of whom hold
Ph.D. degrees and four of whom hold M.D. degrees or foreign equivalent. Of these
employees, 159 are engaged in research, development, clinical development and
manufacturing activities and 58 in marketing and administration.

  The Company considers its relations with its employees to be excellent. None
of its employees is covered by a collective bargaining agreement. The Company
attempts to offer competitive compensation and fringe benefits programs.


PRODUCT LIABILITY

  The testing, manufacturing and marketing of the Company's proposed products
will entail risk of product liability claims. Such risks exist with respect to
products being tested in human clinical trials, as well as products that may be
tested, manufactured or marketed. The Company has obtained insurance of
$10,000,000 against the risk of product liability. However, there can be no
assurance that such coverage will be adequate to cover claims, that the Company
will be able to maintain or increase its current insurance coverage or that
adequate insurance will be available on acceptable terms. Although the Company
has obtained, and will continue to seek to obtain, indemnification agreements
from pharmaceutical companies that may commercialize products based on the
Company's technologies, there can be no assurance that current or future
corporate sponsors, if any, would be willing fully to indemnify the Company, or
would be sufficiently insured.

PATENTS AND PROPRIETARY TECHNOLOGY

  The Company's policy is to protect aggressively its proprietary technology,
and the Company considers the protection of such rights to be important to its
business. In addition to seeking United States patent protection for many of its
inventions, the Company files patent applications in Canada, Japan, Western
European countries and additional foreign countries on a selective basis in
order to protect the inventions deemed to be important to the development of its
foreign business. As of December 31, 1994, the Company had 54 United States
patents as well as 372 foreign counterpart patents, and currently has 62 United
States patent applications and 734 foreign counterpart patent applications
(including designated countries filed under patent treaties) pending. Patents
issued and applied for cover inventions including new types of liposomes and
their preparation, processes for the therapeutic application of liposomes, lipid
purification, lipid based delivery systems and product compositions. The Company
has acquired and licensed proprietary technology from universities, research
organizations and other companies in return for payments and continuing royalty
obligations. The Company has obtained patents in the United States for
inventions which may be employed with respect to ABLC (R), TLC D-99 and TLC C-53
and has patent applications pending in Europe and Japan for such inventions. The
Company has been awarded patents and has patent applications pending for
inventions which may be employed with respect to these and other products in
various selected countries, as well.

  On June 23, 1992, the Company filed suit against Vestar, Inc. ("Vestar"), in
the United States District Court for the District of Delaware, alleging that
Vestar violated United States Patent number 4,229,360 (the "360 Patent")
covering the dehydration of liposomes, which the Company acquired from the
Battelle Institute. The Company asserted that Vestar's product AmBisome
infringed claims of the 360 Patent. Vestar counterclaimed, alleging that the 360
Patent was invalid and that there was no infringement. In December, 1994,
judgment was entered in favor of Vestar, and the Company has determined not to
pursue an appeal from that judgment. The Company does not rely on the 360 Patent
as the primary means of protection for any of its products currently in
development.

  On May 17, 1993, Vestar filed suit against the Company in the United States
District Court for the District of Delaware, seeking a declaratory judgment that
one of the Company's patents (U.S. Patent No. 4,880,635, the "635 Patent") was
invalid, unenforceable and not infringed by Vestar's AmBisome product. The
Company filed a request for reexamination of the 635 Patent in July, 1993, and
requested a stay of Vestar's suit pending completion of the reexamination
process. The court granted a stay, which remains in force, as the reexamination
proceeds. The Company does not intend to rely on the 635 Patent as the primary
means of protection for any of its products currently in development.

  Other public and private institutions, including universities, may have filed
applications for, or have been issued, patents with respect to technology
potentially useful or necessary to the Company. The scope and validity of such
patents, the extent to which the Company may wish or need to acquire licenses
under such patents, and the cost or availability of such licenses, are currently
unknown.

  The Company also intends to rely on unpatented trade secrets and proprietary
know-how and continuing technological innovation to maintain and develop its
commercial position. The Company has entered into confidentiality agreements
with its employees, consultants and advisors, and corporate sponsors.

                                       14

GOVERNMENTAL REGULATION

  Regulation by governmental authorities in the United States and other
countries is a significant factor in the production and marketing of the
Company's products and in its ongoing research and development activities. In
order to test clinically, to produce and to market products for human
therapeutic use, mandatory procedures and safety standards established by the
FDA and comparable agencies in foreign countries must be followed.

  The standard process required by the FDA before a pharmaceutical agent may be
marketed in the United States includes (i) preclinical tests, (ii) submission to
the FDA of an application for an IND which must become effective before human
clinical trials may commence, (iii) adequate and well-controlled human clinical
trials to establish the safety and efficacy of the drug in its intended
application, (iv) submission to the FDA of an NDA with respect to drugs or a
Product License Application ("PLA") with respect to biologics, which
applications are not automatically accepted by the FDA for consideration, and
(v) FDA approval of the NDA or PLA prior to any commercial sale or shipment of
the drug or biologic. In addition to obtaining FDA approval for each product,
each domestic drug manufacturing establishment must be registered or licensed by
the FDA. Domestic manufacturing establishments are subject to inspections by the
FDA and by other Federal, state and local agencies and must comply with Good
Manufacturing Practice as appropriate for production.

  The Company has as yet not submitted an NDA in the United States, and no
assurance can be given that with respect to the Company's NDA for ABLC (R) that
it will be accepted for consideration, that it will be promptly reviewed, that
the FDA will find the data submitted adequate or that it will ultimately be
approved.

  Clinical trials are typically conducted in three sequential phases, but the
phases may overlap. In Phase I, the initial introduction of the drug to humans,
the drug is tested for dosage and tolerance. Phase II involves detailed
evaluation of safety and efficacy. Phase III trials consist of larger scale
evaluation of safety and efficacy and may require larger patient numbers,
depending on the clinical indication for which marketing approval is sought.

  The process of completing clinical testing and obtaining FDA approval for a
new product is likely to take a number of years and require the expenditure of
substantial resources. The FDA may grant an unconditional approval of a drug for
a particular indication or may grant approval conditioned on further
postmarketing testing. Even after initial FDA approval has been obtained,
further studies may be required to provide additional data on safety or to gain
approval for the use of a product as a treatment for clinical indications other
than those for which the product was initially approved. Also, the FDA may
require postmarketing testing and surveillance programs to monitor the drug's
efficacy and side effects. Results of these postmarketing programs may prevent
or limit the further marketing of the products.

  Sales of pharmaceutical products outside of the United States are subject to
regulatory requirements that vary widely from country to country. In the EU, the
general trend has been toward coordination of common standards for clinical
testing of new drugs, leading to changes in various requirements imposed by each
EU country. Generally, the level of regulation in the EU and other foreign
jurisdictions is somewhat less comprehensive and burdensome than regulation in
the United States, but there are differences and, in some respects, foreign
regulations may be more burdensome than FDA requirements. The time required to
obtain regulatory approval from the comparable regulatory agencies in each
foreign country may be longer or shorter than that required for FDA approval.

  In addition, the Company is and may be subject to regulation under state and
federal law regarding occupational safety, laboratory practices, the use 

                                       15
<PAGE>
 
and handling of radioisotopes, environmental protection and hazardous substance
control and to other present and possible future local, state, federal and
foreign regulation.


COMPETITION

  Competition in the pharmaceutical field generally, and in the liposome and
lipid industries in particular, is intense and is based on such factors as
product performance, safety, patient compliance, ease of use, price, physician
acceptance, marketing, distribution and adaptability to various modes of
administration. Technological competition may be based on the development of
alternative products and approaches aimed at the treatment, diagnoses or
prevention of the same diseases as the Company's products.

  Competition from other companies will be based on scientific and technological
factors, the availability of patent protection, the ability to commercialize
technological developments, the ability to obtain government approval for
testing, manufacturing and marketing and the economic factors resulting from the
use of those products, including their price. There are many companies, both
public and private, including well-known pharmaceutical and chemical companies,
many of which have greater capital resources than the Company, which are seeking
to develop lipid and liposome based products as well as products based on other
drug-delivery technologies for therapeutic, diagnostic and vaccine applications.

  The Company is aware that other companies are developing lipid based or
liposomal amphotericin B products. One such company has been selling a liposomal
amphotericin B in certain European countries, including the United Kingdom, for
approximately four years. Another has received approval during 1994 to market
its product, and its licensee is currently marketing such product, in the United
Kingdom and in the Republic of Ireland. No approvals have been granted to market
any such liposomal amphotericin B products in the United States.

  Another company is developing a liposomal doxorubicin product for the
treatment of Kaposi's Sarcoma and certain types of cancer. An advisory committee
of the FDA has voted to recommend that the FDA grant accelerated approval, with
certain qualifications, for this product for treatment of Kaposi's sarcoma where
other agents have failed. No approvals have yet been granted for this product in
the United States.

  Other groups active in the field include colleges, universities, and public
and private research institutions which are becoming more active in seeking
patent protection. These institutions have also become increasingly competitive
in recruiting personnel from a limited number of scientists and technicians.

Item 2.  Properties
- -------------------

  The Company leases space in all of one and a portion of two other facilities
in Princeton, New Jersey and owns a manufacturing facility in Indiana.

  The Company currently leases a building of approximately 50,000 square feet
that houses its scientific laboratories, manufacturing facilities and certain
offices in the Princeton Forrestal Center located near Princeton, New Jersey.
During 1994, the Company renegotiated the lease to provide for a longer initial
term, together with certain renewal options, a reduced initial lease rate, and a
change in structure to a  triple net  lease in exchange for the Company granting
to the lessor a Letter of Credit for $1,000,000. The new lease, with an initial
term of twelve years, commenced January 1, 1995, and the Company has options to
renew for up to an additional ten years. Lease payments for the year ended
December 31, 1994 totaled approximately $828,000. Future lease payments are
subject to certain contractual escalations. The Company also leases
approximately 23,500 square feet of office space also located in the Princeton
Forrestal Center. This lease commenced March 1, 1993, with an initial lease term
of ten years. The Company may terminate this lease at the end of the fifth year.
Lease payments for this lease for the year ended December 31, 1994 totaled
approximately $486,000. In January, 1995, the Company entered into a three year
lease for approximately 13,200 square feet of office/warehouse space near its
corporate offices. The Company also rents office space in London, England.

  In July, 1992, the Company purchased a pharmaceutical manufacturing facility
of approximately 55,000 square feet located on 26 acres of land located in
Indianapolis, Indiana. The Company has begun to refurbish and equip certain

OVERVIEW

  The Company is a leading biotechnology company engaged in the discovery,
development and, recently, the commercialization of proprietary lipid and
liposome-based pharmaceuticals for the treatment, prevention and diagnosis of
inadequately treated, life-threatening illnesses. The Company is currently
launching its first product, amphotericin B lipid complex (ABLC(R) or, in
Europe, AbelcetTM), which has been approved for marketing for certain
indications in the United Kingdom and is the subject of marketing application
filings in eighteen other countries. The Company expects to file an NDA for
ABLC(R) in the United States during 1995. In addition to ABLC(R)/AbelcetTM, the
Company's other lead products are TLC D-99 and TLC C-53. TLC D-99, liposomal
doxorubicin, is being developed in conjunction with Pfizer primarily as a first
line treatment of metastatic breast cancer, and is undergoing Phase III clinical
testing in the United States. The Company has completed a Phase II clinical
trial for TLC C-53 for the treatment of ARDS and is preparing a protocol for a
pivotal clinical trial of TLC C-53, liposomal prostaglandin E1, for ARDS. In
January, 1995, the Company commenced a Phase II clinical trial of TLC C-53 for
the treatment of AMI, or heart attack. The Company and Schering AG entered into
a collaborative research and development agreement with respect to TLC I-16, a
non-ionic contrast agent for use in connection with CT scanning of the liver.
TLC I-16 is currently in preclinical development. The Company also has a
continuing discovery research program which concentrates primarily on the
treatment of cancer and inflammatory conditions.

RESULTS OF OPERATIONS

 Revenues

  Total revenues for the year ended December 31, 1994 were $10,440,000, a
decrease of $2,602,000 or 20.0% as compared to the year ended December 31, 1993.
Revenues in 1993 were $13,042,000, an increase of $2,153,000 or 19.8% compared
to the 1992 level. The primary components of revenues for the Company are
collaborative research and development activities, interest and investment
income, and licensing and other fees. These components can increase or decrease
significantly based on the number and amount of research collaborations,
including the achievement of developmental milestones, the initiation of new
licensing agreements and, in the case of interest and investment income, the
level of cash balances available for investment and the rate of interest earned
on such investments.

  Collaborative research and development revenues were $5,831,000 for 1994,
which was $954,000 or 19.6% higher than 1993 revenues. Collaborative research
and development revenues were $4,877,000 for 1993, which was $890,000 or 15.4%
lower than 1992. The Company earned substantially all of its collaborative
research and development revenues from two corporate sponsors in 1994 and 1993
and three sponsors in 1992. In January, 1993, the Company reacquired the
worldwide rights to ABLC(R) from Bristol-Myers Squibb ("BMS"), a former
corporate sponsor. The Company assumed the responsibilities and funding for
clinical development, manufacturing and marketing of ABLC(R). The financial
impact of the reacquisition was the absence of research and development
reimbursements from BMS in 1993 and 1994. Through January, 1995, the Company
filed marketing applications for ABLC(R)/AbelcetTM in eighteen countries and in
June, 1994, began Phase III clinical trials in the United States for the drug.
During February, 1995, the Company received approval to market AbelcetTM in the
United Kingdom for certain indications. During 1992, the Company completed work
under a research agreement related to a certain diagnostic product with Schering
AG; additional work under an amended research agreement with Schering AG began
in the third quarter of 1993 and continued through 1994.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
- --------------------------------------------------------------------------------
of Operations
- -------------

  Licensing and other fees were $50,000, $541,000 and $312,000 for 1994, 1993
and 1992, respectively. The change in this category from 1992 to 1994 was
directly related to an agreement with Wyeth-Ayerst for TLC A-60, a liposomal
vaccine adjuvant which required payments as follows: $250,000 in 1992, $500,000
in 1993 with no payment being scheduled in 1994. Wyeth-Ayerst recently advised
the Company that it is no longer pursuing development of TLC A-60 and that it
intends to return all rights to the Company.

  Interest and investment income for the years ended December 31, 1994, 1993,
and 1992 was $4,559,000, $7,624,000, and $4,810,000, respectively. Interest and
investment income in 1994 decreased by $3,065,000 or 40.2% from 1993. Interest
and investment income in 1993 was $2,814,000 or 58.5% greater than that in 1992.
During the first quarter of each of 1993 and 1992 the Company raised capital
through the sale of equity securities. Net proceeds to the Company from these
sales were $65,735,000 and $44,603,000, respectively. No significant amounts of
capital were raised during 1994. Fluctuations in interest and investment income
are primarily due to the significant changes in the level of cash balances the
Company has available for investment as a result of these financings. The
Company expects that interest and investment income in 1995 will be
substantially less than that reported in 1994 due to the anticipated lower level
of cash and securities in its portfolio.


 Expenses

  Total expenses for 1994 of $44,093,000 increased $8,574,000 or 24.1% compared
to 1993. Total expenses of $35,519,000 for 1993 increased $14,955,000 or 72.7%
compared to 1992. The increase in expenses for each year reflects the greater
funding required to support the clinical study programs of its lead proprietary
products as these products progress through late-stage trials, and the expansion
of the Company's research and development efforts.

  Research and development expenses accounted for 71.0% of the expense increase
from 1992 to 1994, while general and administrative and interest expenses
accounted for the remainder. At year-end 1992, the Company's efforts were
focused on research and pharmaceutical development using a small organization to
support early stage clinical trial activities. During 1993, the Company
significantly expanded its capability to design and monitor clinical trials,
both in the U.S. and internationally and also added internal capabilities in
biostatistics and regulatory affairs. During 1994, the Company continued to
strengthen these activities and developed an internal manufacturing organization
capable of producing clinical and commercial material and began to establish an
international sales and marketing organization.

  Research and development expenses of $31,713,000 for 1994 increased $6,641,000
or 26.5% over 1993. The primary components of this increase were the costs
related to ABLC(R)/AbelcetTM, TLC C-53 and TLC D-99, reflecting higher
expenditures associated with the Company's products progressing to late stages
of development; increased staffing levels to support the new manufacturing
facility located in Princeton, which began operations in early 1994; and the
expansion of the Company's medical, regulatory, and biostatistical departments
to develop and conduct increased clinical trial activity. As in prior years,
costs associated with the development of TLC D-99 were reimbursed by Pfizer
under the terms of a licensing agreement, signed in 1990. In February, 1994, the
Company announced that it had suspended further development of Maitec(R), its
liposomal gentamicin product, in order to focus its resources on its other
products.

of Operations
- -------------

  Research and development expenses of $25,072,000 for 1993 increased
$10,072,000 or 67.1% over 1992. The significant part of the increase was related
to assuming the on-going development costs of ABLC(R) that were previously
incurred by BMS. All rights to ABLC(R) were reacquired from BMS in January 1993.
The 1993 increase also included the expansion of preclinical studies for TLC C-
53 and clinical study programs of Maitec(R), TLC C-53, and TLC D-99. The Company
also increased research and development staff including medical, regulatory,
biostatistical, manufacturing and scientific personnel to support the
preclinical and clinical study programs.

  General and administrative expenses in 1994 were $12,072,000, an increase of
$1,879,000 or 18.4% over 1993. The primary component of the increase was costs
associated with the start up of the international sales and marketing operations
in anticipation of launching the Company's first product, amphotericin B lipid
complex, using the trademark AbelcetTM. By year-end 1994, the Company had filed
applications to market AbelcetTM in seventeen countries, and approval to market
in the United Kingdom was received in February, 1995.

  General and administrative expenses in 1993 were $10,193,000, an increase of
$4,705,000 or 85.7% over 1992. The main reason for the increase was the cost
associated with litigation brought by the Company for patent infringement. The
court found in favor of the defendant, and the Company has decided not to
appeal. The balance of the increase was due to the expansion of various
administrative functions consistent with the growth of the Company.

  The Company expects both its research and development expenses and its general
and administrative expenses to continue to increase as it pursues the clinical
development of its products, launches AbelcetTM in the United Kingdom and
prepares for future potential marketing approvals in other European countries.

  Interest expense for 1994 was $308,000 compared to $254,000 for 1993. The
increase of $54,000 in interest expense was primarily due to a sale-leaseback
agreement that funded machinery and construction costs within the Princeton
manufacturing facility. This capital lease arrangement was initiated in 1993 and
completed in early 1994. The increase in 1993 versus 1992 of $178,000 was due to
the 1992 acquisition of a 55,000 square foot manufacturing facility in
Indianapolis, Indiana, which was partially funded by a mortgage-backed note
payable.


 Preferred Stock Dividends

  In January 1993, the Company completed the issuance of 2,760,000 Depositary
Shares representing 276,000 shares of Series A Cumulative Convertible
Exchangeable Preferred Stock with a cumulative dividend of 7.75%. The Company
has declared and paid dividends of $5,348,000 on such Preferred Stock annually
during 1993 and 1994. These dividends are included as part of the Company's net
loss applicable to Common Stock and net loss per share of Common Stock.


 Net Loss, Net Loss Applicable to Common Stock and Net Loss Per Share of
Common Stock

  The net loss of $33,653,000 for 1994 increased by $11,176,000 or 49.7%
compared to 1993. This increase in net loss was due to the increase in total
expenses of $8,574,000, in conjunction with a decrease in total revenues of
$2,602,000. The net loss applicable to Common Stock was $39,001,000 in 1994 and
$27,825,000 in 1993 as a result of the operational factors discussed above and
the declaration of $5,348,000 of Preferred Stock dividends in each year. The net
loss per common share increased by $.46 per share to $1.64 per share 

                                       25
<PAGE>
 
for 1994. The total loss per share of $1.64 comprises $.23 for Preferred Stock
dividends and the remainder, $1.41, for the current year net loss.

  The net loss of $22,477,000 for 1993 increased by $12,802,000 or 132% compared
to 1992. This increase in net loss was due to the increase in total expenses of
$14,955,000, partially offset by an increase in total revenues of $2,153,000.
The net loss applicable to Common Stock was $27,825,000 in 1993 compared to
$9,675,000 in 1992. The increase was due to the operational factors discussed
above and inclusion in 1993 of $5,348,000 in Preferred Stock dividends. The 1993
net loss per common share increased by $.75 per share to $1.18 per share. The
increase is attributable to the $5,348,000 of Preferred Stock dividends, or $.23
per share, and the balance is due to the increase in net loss of $.52 per share.

  Liquidity and Capital Resources
  -------------------------------

  The Company had $72,157,000 in cash reserves as of December 31, 1994. The cash
reserves include cash and cash equivalents of $2,369,000, short-term investments
of $55,487,000, long-term investments of $9,421,000 and restricted cash of
$4,880,000. The cash reserves decreased $47,586,000 from 1993 due to the use of
funds for operations, capital acquisitions, Preferred Stock dividend payments
and a current market value adjustment to investments to comply with the
Statement of Financial Accounting Standards ("SFAS") No. 115, Accounting for
Certain Investments in Debt and Equity Securities. The cumulative effect at
December 31, 1994 of SFAS No. 115 was a net unrealized loss of $5,033,000. In
connection with certain financing arrangements, the Company is required to
maintain minimum cash balances, of which the largest requirement is $20,000,000.
The Company invests its excess cash in a diversified portfolio of high-grade
marketable and United States Government-backed securities.

  During 1994, cash used by operations increased to $32,407,000 as compared to
$18,948,000 in 1993. The 1994 change in cash used was primarily due to the
increase in net loss versus 1993 combined with the increase in other current
assets and the reduction in accounts payable. This was partially offset by
increases in depreciation and amortization, along with accrued expenses. Funding
required for operating activities during 1994 was derived from existing cash
balances and the sales of investments as well as from corporate sponsors,
interest income, and the exercise of stock options. Plant acquisitions decreased
in 1994 compared to 1993, reflecting the completion of the expansion of the
clinical research and manufacturing facilities begun in 1993. The Company
expects to make renovations costing between approximately $11,000,000 to
$13,000,000 at the Indianapolis facility.

  At December 31, 1994, the Company had approximately $101,412,000 of operating
loss carryforwards, $2,860,000 of research and development credit carryforwards
and $45,000 of investment tax credit carryforwards. These carryforwards expire
in the years 1996 through 2009. The timing and manner in which these losses are
used may be limited as a result of certain ownership changes that occurred
pursuant to Internal Revenue Service regulations under Section 382.

  The Company expects to finance its operations from, among other things, the
proceeds received from payments under research and development agreements,
interest earned on investments, liquidation of certain investments and product
sales. Funds may also be provided to the Company by leasing arrangements for
capital expenditures and from the licensing of its products. The Company expects
to fund Preferred Stock dividends from existing cash reserves. The Company
believes that its available cash and marketable securities, revenues from
research and development contracts and interest income will be sufficient to
meet its expected operating and capital cash flow requirements for the
intermediate term.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Stockholders
of The Liposome Company, Inc.:



  We have audited the consolidated balance sheets of The Liposome Company, Inc.
and Subsidiaries as of December 31, 1994 and 1993, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1994.  These financial statements
are the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

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

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of The Liposome
Company, Inc. and Subsidiaries as of December 31, 1994 and 1993, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1994, in conformity with generally
accepted accounting principles.

  As discussed in Note 1 to the consolidated financial statements, in 1993 the
Company changed its method of accounting for certain investments in debt and
equity securities.

                  THE LIPOSOME COMPANY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:


BUSINESS:

  The Liposome Company, Inc. (the "Company") is a leading biotechnology company
engaged in the discovery, development and, recently, the commercialization of
proprietary lipid and liposome-based pharmaceuticals for the treatment,
prevention and diagnosis of inadequately treated, life-threatening illnesses.
The Company is currently launching its first product, amphotericin B lipid
complex (ABLC(R) or, in Europe, AbelcetTM), which has been approved for
marketing for certain indications in the United Kingdom and is the subject of
marketing application filings in eighteen other countries. The Company expects
to file an NDA for ABLC(R) in the United States during 1995. In addition to
ABLC(R)/AbelcetTM, the Company's other lead products are TLC D-99 and TLC C-53.
TLC D-99, liposomal doxorubicin, is being developed in conjunction with a
corporate sponsor primarily as a first line treatment of metastatic breast
cancer. TLC C-53, liposomal prostaglandin E1, is being developed for the
treatment of acute respiratory distress syndrome and acute myocardial
infarction. The Company is also developing a contrast agent for CT scanning and
has a continuing discovery research program which concentrates primarily on the
treatment of cancer and inflammatory conditions.


CONSOLIDATED FINANCIAL STATEMENTS:

  The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All intercompany transactions and balances are
eliminated in consolidation.


REVENUE RECOGNITION AND UNEARNED CONTRACT INCOME:

  Payments for collaborative research and development are generally received in
advance and are recognized as revenue, ratably, as the research and development
is performed. Licensing fees, royalty and hurdle payments are recognized in the
period earned.

  The Company has entered into various collaborative research and development
contracts. The Company earned substantially all of its research and development
revenues from two corporate sponsors in 1994 and 1993, and three in 1992.
Corporate sponsors who contributed 10% or more of the Company's total revenues,
pursuant to collaborative agreements and licensing and other fees as reported in
the statements of operations, in any year were as follows:

RESEARCH AND DEVELOPMENT EXPENSES:

  The research and development expenses of the Company, which are expensed as
incurred, include those efforts related to collaborative research and
development agreements, development of the Company's proprietary products and
general research. The expenses include, but are not limited to, medical,
biostatistical, regulatory, manufacturing and scientific support costs.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

DEPRECIATION AND AMORTIZATION:

  Building and building improvements, furniture and fixtures, automobiles, and
machinery and equipment are depreciated by the straight-line method over their
estimated useful lives ranging from three to twenty years. Leasehold
improvements and machinery and equipment under capital leases are amortized by
the straight-line method over the lesser of their estimated useful lives or the
terms of the related leases. Purchased patents are amortized by the straight-
line method over their life as determined by the country of issuance. The
Company reviews the realizability of the patents on a quarterly basis.


CASH EQUIVALENTS:

  The Company considers all highly liquid investments with maturities of three
months or less as cash equivalents.


INVESTMENTS:

  Short-term investments represent marketable securities available for current
operations, all of which have been classified as available for sale, while long-
term investments represent marketable securities available for expected capital
acquisitions. These investments, which are all investment grade, are stated at
market value of the portfolio.

  On December 31, 1993, the Company adopted the provisions of the Statement of
Financial Accounting Standards ("SFAS") No. 115, Accounting for Certain
Investments in Debt and Equity Securities. This Statement requires certain
investments in debt and equity securities to be reported at current market
value. Prior to 1993 investments were carried at the lower of cost or market.

  For the years ended December 31, 1994 and 1993, investment income includes
gross realized gains of $150,000 and $765,000, respectively. At December 31,
1994 and 1993, investments included gross unrealized gains of $7,000 and
$845,000 and losses of $5,040,000 and $195,000, respectively. The fair values of
debt securities maturing within one year and after one year but less than 5
years, amounted to $5,954,000 and $57,148,000, respectively.

RESTRICTED CASH:

  The Company has entered into certain financing arrangements that require the
issuance of letters of credit that are partially secured by certain securities.
The aggregate amount of these securities are segregated and identified as
restricted cash. The Company is also required to maintain minimum cash balances
in connection with these financings.

NET LOSS PER SHARE APPLICABLE TO COMMON STOCK:

  Net loss per share applicable to Common Stock is computed based on the
weighted average of the Common Stock shares outstanding. Common Stock
equivalents are not included in the computation of weighted average shares
outstanding since the effect would be anti-dilutive.

RECLASSIFICATION:

  Certain reclassifications have been made to the prior year financial statement
amounts to conform with the presentation in the current year financial
statements.

9.   INCOME TAXES:

  The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards No. 109 "Accounting for Income
Taxes" ("SFAS 109"). SFAS 109 requires recognition of deferred tax liabilities
and assets for the expected future tax consequences of events that have been
included in the financial statements or tax returns. Under this method, deferred
tax liabilities and assets are determined based on the difference between the
financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to reverse.
The Company provides a valuation allowance against the net deferred tax debits
due to the uncertainty of realization. The increase in the valuation allowance
for the year ended December 31, 1994 was $16,050,000.

               ---------------------                                           
Company shall be required to redeem any shares of Series A or B Preferred Stock,
or if pursuant to Section 2.1(b) hereof a holder of Series A or B Preferred
Stock shall become entitled to request redemption of shares of Series A or B
Preferred Stock, notice thereof shall be sent, at least 60 days prior to the
date fixed for redemption in the case of redemption pursuant to Section 2.1(a),
and as promptly as practicable following occurrence

                                       7
<PAGE>
 
of the Event of Default in the case of redemption pursuant to Section 2.1(b), to
each holder of record whose stock is to be or is entitled to be redeemed, as the
case may be, by registered or certified mail, postage paid, addressed to such
holder at such holder's address as the same shall appear on the books of the
Company.  Such notice shall (a) if given pursuant to Section 2.1(a), state that
the Company is required to redeem such shares, or if given pursuant to Section
2.1(b), state that such holder may at his option request that the Company redeem
all or part of his shares, (b) state, if applicable, the date fixed for the
redemption thereof, (c) state the per share redemption price, and (d) if such
redemption is pursuant to Section 2.1(a), call upon such holder to surrender to
the Company on or after said date at the place designated in such notice, a
certificate or certificates representing the number of shares to be redeemed in
accordance with such notice or, if such redemption is pursuant to Section
2.1(b), state that such holder may surrender certificates representing some or
all of his shares at the place designated in such notice.  If less than all of
the outstanding shares of Series A and B Preferred Stock are to be redeemed
pursuant to Section 2.1(a), or less than all of the shares of Series A and B
Preferred Stock as to which redemption has been duly

                                       8
<PAGE>
 
requested are to be redeemed pursuant to Section 2.1(b), the shares of each
holder to be redeemed shall be determined pro rata based upon the proportion
                                          --- ----                          
which (i) the sum of the number of shares of Series A and B Preferred Stock and
Preferred Stock Equivalents (as defined below) then held by each holder bears to
(ii) the aggregate number of shares of Series A and B Preferred Stock and
Preferred Stock Equivalents then held by all such holders immediately prior to
such redemption.  For purposes of this Article FOURTH, a "Preferred Stock
Equivalent" shall mean any Common Stock issued upon conversion of a share of
Series A or B Preferred Stock or any Common Stock or other security issued in
exchange for or in replacement of a share of Series A or B Preferred Stock or
Preferred Stock Equivalent, and for purposes of any computation or vote
involving such Preferred Stock Equivalents provided for herein the aggregate of
all Preferred Stock Equivalents issued in respect of a share of Series A or B
Preferred Stock shall be deemed the equivalent of one share of Series A or B
Preferred Stock.  On or after the date fixed in such notice of redemption in the
case of redemption pursuant to Section 2.1(a), or at any time following receipt
of such notice of redemption in the case of redemption pursuant to Section
2.1(b), each holder of shares of Series A or B Preferred Stock to be so redeemed

                                       9
<PAGE>
 
shall present and surrender the certificate or certificates for such shares to
the Company at the place designated in said notice and thereupon the redemption
price of such shares shall be paid to, or to the order of, the person whose name
appears on such certificate or certificates as the owner thereof.  From and
after the date fixed in any such notice as the day of redemption, unless default
shall be made by the Company in providing for the payment of the redemption
price pursuant to such notice, all dividends on the Series A or B Preferred
Stock thereby called for redemption pursuant to Section 2.1(a) hereof shall
cease to accrue and all rights of the holders thereof as shareholders of the
Company, except the right to receive the redemption price (but without interest
thereon), shall cease and terminate, provided, however, that the Company shall
deposit the amount required for the payment of any part of the redemption price
not claimed on the redemption date with a bank or trust company doing business
in the State of New York and having a capital and surplus of at least
$250,000,000.  Any interest allowed on moneys so deposited which shall remain
unclaimed by the holders of the Series A and B Preferred Stock at the end of six
years after the redemption date shall be paid by such bank or trust company to
the Company, but the Company shall remain obligated to

                                      10
<PAGE>
 
make payment thereof to the holders of Series A or B Preferred Stock entitled
thereto (subject to any applicable escheat or similar laws).  Any shares of
Series A or B Preferred Stock

redeemed by the Company pursuant to either Section 2.1(a) or Section 2.1(b)
shall be retired and shall not be reissued and the Company may from time to time
take such appropriate corporate action as may be necessary to reduce the
authorized Series A or B Preferred Stock.

          2.3. Transfer Books.  In order to facilitate the redemption of any
               --------------                                               
shares of Series A and B Preferred Stock, the Board of Directors of the Company
is authorized to cause the transfer books for such Series A and B Preferred
Stock to be closed as to the shares to be redeemed.

          2.4. Events of Default.  For purposes of this Section 2, an Event of
               -----------------                                              
Default under this [Article] shall be deemed to have occurred (i) if dividends
accrued on, or amounts required to be paid in redemption of, the Series A or B
Preferred Stock are not paid by the Company when due; (ii) if the Company or any
of its subsidiaries shall (a) admit in writing its inability to pay its debts
generally as they become due, (b) file a petition or answer or consent seeking
relief under the Federal Bankruptcy Code, as now constituted or hereafter
amended, or any other applicable Federal or state bankruptcy or insolvency law
or other

                                      11
<PAGE>
 
similar law, (c) consent to the institution of proceedings under any law listed
in (b) above, or to the filing of any such petition or to the appointment or
taking possession of a receiver, liquidator, assignee, trustee, custodian (or
other similar official) of the Company or any such subsidiary or of any
substantial part of their property, or (d) make an assignment for the benefit of
its creditors; (iii) if a decree or order shall be entered by a court for relief
in respect of the Company or any of its subsidiaries under the Federal
Bankruptcy Code, as now constituted or hereafter amended, or any other
applicable Federal or state bankruptcy or insolvency law or other similar law,
or appointing a receiver, liquidator, assignee, trustee (or similar official) of
the Company or any such subsidiary or of any substantial part of their property
or ordering the winding-up or liquidation of their affairs and such decree or
order shall not be vacated or set aside or stayed within a period of 30 days
from the date of entry thereof; (iv) if the Company willfully fails in any
material respect to perform or observe any material agreement, covenant or
obligation set forth in the Convertible Preferred Stock Purchase Agreement dated
as of November 12, 1982 among the Company, The Liposome Company, a New Jersey
limited partnership, and certain purchasers of the Company's Series A or

                                      12
<PAGE>
 
B Preferred Stock; or (v) if default in the observance of the covenant set forth
in Section 10.5 of said Purchase Agreement shall have occurred and be
continuing.

          3.  Conversion Rights.  The holders of shares of Series A or B
              -----------------                                         
Preferred Stock shall have the right, at their option, to convert such shares
into shares of Common Stock at any time on and subject to the following terms
and conditions:

              (a)  Conversion Price.  Each share of the Series A and B Preferred
                   ----------------                               
Stock shall be convertible at the office of the Company, or at the office of the
transfer agent, if any, for the Series A and B Preferred Stock, into such number
of fully paid and nonassessable shares of Common Stock as shall equal the
quotient of (i) in the case of the Series A Preferred Stock, $.7234 divided by
the Series A Conversion Price, determined as hereinafter provided, in effect at
the time of conversion and (ii) in the case of the Series B Preferred Stock,
$1.2307 divided by the Series 3 Conversion Price, determined as hereinafter
provided, in effect at the time of conversion.  The price at which shares of
Common Stock shall be deliverable upon conversion of the Series A Preferred
Stock (the "Series A Conversion Price") shall initially be $.7234 and the price
at which shares of Common Stock shall be deliverable upon conversion of the

                                      13
<PAGE>
 
Series B Preferred Stock (the "Series B Conversion Price") shall initially be
$1.2307. Such Conversion Prices shall be adjusted in certain instances as
provided below in Section 4.

          (b)  The holders of shares of Series C Preferred Stock shall have the
right, at their option, to convert such shares into shares of Common Stock on a
one-to-one basis, subject to approval by the Board of Directors, and subject to
appropriate adjustment for subdivisions and combinations, at any time after
February 15, 1984; provided, however, that all outstanding shares of Series C
Preferred Stock shall be converted automatically into shares of Common Stock
upon the first underwritten offering of the Company's Common Stock to the
general public effected pursuant to a registration statement filed with the
Securities & Exchange Commission under the Securities Act of 1933, as amended,
on a one-to-one basis, subject to appropriate adjustment for subdivisions and
combinations.  Shares of Series C Preferred Stock automatically converted shall
be deemed to have been converted on a date immediately prior to such public
offering, as selected by the Board of Directors of the Company, and the person
or persons entitled to receive the Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or

                                      14
<PAGE>
 
holders of such Common Stock on such date selected by the Board of Directors.

          (c) In case of any merger, consolidation or reorganization of the
Company into or with any other corporation, a merger of any other corporation
into the Company, or a sale, lease, mortgage, pledge, exchange, transfer or
other disposition by the Company of all or substantially all of its assets, or
any reclassification of the stock of the Company (other than a change in par
value or from no par value to par value or from par value to no par value, or as
a result of a stock dividend or subdivision or a combination of shares), each
share of Series C Preferred Stock shall thereafter be convertible into the
number of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock deliverable upon conversion of such Series
C Preferred Stock would have been entitled upon such consolidation, merger,
disposition or reclassification; and, in any such case, appropriate adjustment
(as determined in good faith by the board of directors) shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of the holders of Series C Preferred Stock, to the end that
the provisions set forth herein shall thereafter be applicable, as nearly as
reasonably may be, in

                                      15
<PAGE>
 
relation to any shares of stock or other property thereafter deliverable upon
the conversion of the Series C Preferred Stock.

          (d) Dividends.  Payment or adjustment shall be made upon any
              ---------                                               
conversion on account of any dividends declared but not yet paid on the shares
of Series A, B or C Preferred Stock surrendered for conversion and on the shares
of Series C Preferred Stock automatically converted or on account of any
dividends declared but not yet paid on the Common Stock issued upon such
conversion.

          (e) Conversion of Series A, B or C Preferred Stock.  In order to
convert shares of Series A, B or C Preferred Stock into Common Stock or to
formally reflect the automatic conversion of shares of Series C Preferred Stock
into Common Stock, the holder thereof shall surrender the certificate or
certificates therefor at the office of the Company or of the transfer agent
hereinabove mentioned, and the holder shall give written notice to the Company
therewith that he elects to convert such shares.  If any holder of shares of
Series A, B or C Preferred Stock shall desire to have the certificate or
certificates for shares of Common Stock issued in a name or names other than the
name or names of the holder or holders of record of such shares of Series A, B
or C Preferred Stock, such certificate or certificates

                                      16
<PAGE>
 
shall be duly endorsed to the transferee or in blank or shall be accompanied by
a proper instrument or instruments of assignment to such transferee or in blank;
such certificate or certificates shall also be accompanied by proof of payment
of any applicable transfer taxes.  Shares of Series A or B Preferred Stock and
shares of Series C Preferred Stock converted at the holder's option shall be
deemed to have been converted immediately prior to the close of business on the
date of the surrender of such shares for conversion as provided above
("Conversion Date"), and the person or persons entitled to receive the Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such Common Stock on the Conversion Date.  As
promptly as practicable on or after the Conversion Date (or, in the case of
automatic conversion of Series C Preferred Stock, on or after the date the
certificates for shares of Series C Preferred Stock are surrendered as provided
above), the Company will issue and deliver, at the office at which such
surrender is made, (i) a certificate or certificates for the number of full
shares of Common Stock issuable upon such conversion, together with an
appropriate portion of the applicable Conversion Price in cash in lieu of any
fraction of a share, and (ii) a new certificate or certificates for the numbers
of shares of

                                      17
<PAGE>
 
Series A, B or C Preferred Stock, if any, represented by the certificate or
certificates surrendered but not converted, to the person or persons entitled to
receive the same.

          (f) Cancellation of Series A, B or C Preferred Stock.  All shares of
Series C Preferred Stock automatically converted, and all shares of Series A, B
or C Preferred Stock which shall have been surrendered for conversion at the
holder's option as herein provided, shall no longer be deemed to be outstanding,
and all rights with respect to such shares, including the rights, if any, to
receive notices and to vote, shall forthwith cease and terminate except only the
right of the holders thereof to receive shares of Common Stock in exchange
therefor and payment of any accrued and unpaid dividends thereon, provided,
however, that the provisions of this Section 3(f) shall not affect any rights
which holders of Series A, B or C Preferred Stock may enjoy under any separate
instrument or agreement pursuant to which such Series A, B or C Preferred Stock
is issued or sold.  Any shares of Series A, B or C Preferred Stock so converted
shall be retired and cancelled and shall not be reissued.

     4.   Adjustment of Conversion Prices.  The Series B Conversion Price and
          -------------------------------                                    
(subject to subsection 4(g) hereof) the Series A Conversion Price from time to
time in effect shall

                                      18
<PAGE>
 
be subject to adjustment (to the nearest tenth of a cent) from time to time as
follows:

          (a) Stock Dividends, Subdivisions and Combinations.  If the Company
              ----------------------------------------------                 
shall:
               (1) declare a dividend payable in, or a distribution of, Common
     Stock, to the holders of any other class or series of the Company's capital
     stock, or

               (2) subdivide its outstanding shares of Common Stock into a
     larger number of shares of Common Stock, or

               (3) combine its outstanding shares of Common Stock into a smaller
     number of shares of Common Stock, then each Conversion Price shall be
     adjusted to that price determined by multiplying such Conversion Price by a
     fraction (i) the numerator of which shall be the total number of
     outstanding shares of Common Stock immediately prior to such event, and
     (ii) the denominator of which shall be the total number of outstanding
     shares of Common Stock immediately after such event.

          (b) Issuance of Additional Shares of Common Stock.  If the Company
              ---------------------------------------------                 
shall (except as hereinafter provided) issue any additional shares of Common
Stock (whether original issuance or out of treasury shares) for a

                                      19
<PAGE>
 
consideration per share less than either Conversion Price, then such Conversion
Price upon each such issuance shall be adjusted to that price determined by
multiplying such Conversion Price by a fraction:

               (1) the numerator of which shall be the number of shares of
     Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock plus the quotient resulting from dividing
     the aggregate consideration received for such additional shares of Common
     Stock by the Conversion Price (as in effect immediately prior to the
     adjustment provided for herein) and

               (2) the denominator of which shall be the number of shares of
     Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock, plus the number of such additional
     shares of Common Stock so issued.

          The provisions of this subsection shall not apply to any additional
shares of Common Stock which are distributed to holders of the Company's capital
stock as a stock dividend, for which an adjustment is provided for under
subsection (a) of this Section.  No adjustment of the Conversion Price shall be
made under this subsection upon the issuance of any additional shares of Common
Stock which

                                      20
<PAGE>
 
are issued pursuant to the exercise of any warrants, options, or other
subscription or purchase rights or pursuant to the exercise of any conversion or
exchange rights in any convertible securities, if any such adjustment shall
previously have been made upon the issuance of such warrants, options or other
rights or upon the issuance of such convertible securities (or upon the issuance
of any warrants, options or other rights therefor) pursuant to subsection (c) of
this Section.

          (c) Issuance of Warrants, Options, Other Rights or Convertible
              ------------------------------------------- --------------
Securities.  In case the Company shall issue any warrants, options or other
- ----------                                                                 
rights to subscribe for or purchase (i) any additional shares of Common Stock or
(ii) any convertible securities, or in case the Company shall issue any
convertible securities, and, in either such case, the consideration per share
for which additional shares of Common Stock may at any time thereafter be
issuable pursuant to such warrants, options or other rights or pursuant to the
terms of such convertible securities shall be less than the Conversion Price,
then the Conversion Price upon each such issuance shall be adjusted to that
price determined by multiplying the Conversion Price by a fraction:

               (1) the numerator of which shall be the number of shares of
     Common Stock outstanding

                                      21
<PAGE>
 
     immediately prior to the issuance of such warrants, options or other
     rights, or such convertible securities, plus the quotient resulting from
     dividing the aggregate consideration received in respect of additional
     shares of Common Stock issuable pursuant to such rights or upon conversion
     of such convertible securities (equal to the aggregate consideration
     received for such rights or convertible securities plus the aggregate
     additional consideration, if any, required to exercise such rights or
     convert such securities) by the Conversion Price (as in effect immediately
     prior to the adjustment provided for herein) and

               (2) the denominator of which shall be the number of shares of
     Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock, plus the maximum number of additional
     shares of Common Stock issuable pursuant to all such warrants, options or
     other rights or necessary to effect the conversion or exchange of all such
     convertible securities.

          (d) Change in Warrants, Options, Other Rights or Convertible
              -------------------------------------------- -----------
Securities.  Upon any change in the number of shares of Common Stock deliverable
- ----------                                                                      
upon the exercise of any

                                      22
<PAGE>
 
warrants, options, other rights or convertible securities covered in subsection
4(c), or upon any change in the minimum purchase price of such warrants,
options, rights or convertible securities, other than a change resulting from
the antidilution provisions of such warrants, options, rights or convertible
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have obtained had the adjustment made upon the
issuance of such warrants, options, rights or convertible securities not
exercised, converted or exchanged prior to such change been made upon the basis
of such change; provided, however, that no readjustment pursuant to the terms of
this subsection 4 (d) shall have the effect of increasing the Conversion Price
to an amount which exceeds the initial Conversion Price set forth in subsection
3(a) or as such Conversion Price shall have been adjusted pursuant to subsection
4(a).

          (e) Mergers and Consolidations.  In case of any merger, consolidation
              --------------------------                                       
or reorganization of the Company into or with any other corporation, a merger of
any other corporation into the Company, or a sale, lease, mortgage, pledge,
exchange, transfer or other disposition by the Company of all or substantially
all of its assets, or any reclassification of the stock of the Company (other
than a change in par value or from no par value to par value or

                                      23
<PAGE>
 
from par value to no par value, or as a result of a stock dividend or
subdivision or a combination of shares), each share of Series A or B Preferred
Stock shall thereafter be convertible into the number of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock deliverable upon conversion of such Series A or B Preferred Stock would
have been entitled upon such consolidation, merger, disposition or
reclassification; and, in any such case, appropriate adjustment (as determined
in good faith by the board of directors) shall be made in the application of the
provisions herein set forth with respect to the rights and interests thereafter
of the holders of the Series A or B Preferred Stock, to the end that the
provisions set forth herein (including provisions with respect to adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property thereafter
deliverable upon the conversion of the Series A or B Preferred Stock.

          (f) Alternative Adjustment.  Notwithstanding the foregoing, at such
              ----------------------                                         
time as adjustment of the Conversion Price shall have been required hereunder in
respect of shares of Common Stock or convertible securities or warrants, options
or other rights to subscribe for or

                                      24
<PAGE>
 
purchase shares of Common Stock or convertible securities, representing an
aggregate of at least 20% of the difference between (i) the number of shares of
Common Stock outstanding (assuming conversion of the Series A and B Preferred
Stock and any other convertible securities then outstanding) immediately prior
to the event first requiring adjustment pursuant to this subsection 4(f) and
(ii) the number of shares of Common Stock in respect of which such adjustment
has theretofore been required, the Conversion Price shall thereafter be
adjusted, in the case of any event requiring adjustment of the Conversion Price
pursuant to subsections 4(b) or 4(c) above, to such lower price as shall equal
the consideration per share for which shares of Common Stock were issued in, or
are issuable as a result of, such event.

          (g) Series A Adjustments.  Prior to November 12, 1984, the Series A
              --------------------                                           
Conversion Price shall be adjusted, if necessary, as provided in subsections
4(a)-4(f) above.  Thereafter, the Series A Conversion Price shall be adjusted,
in lieu of further adjustments pursuant to the foregoing subsections 4(a)-4(f),
upon the occurrence of any event requiring adjustment of the Series B Conversion
Price pursuant to this Section 4, to that price determined by multiplying the
Series A Conversion Price by a fraction, the numerator of which shall be the new
Series B Conversion

                                      25
<PAGE>
 
Price resulting from such adjustment of the Series B Conversion Price and the
denominator of which shall be the Series B Conversion Price in effect
immediately prior to such adjustment of the Series B Conversion Price.

          (h) Other Provisions Applicable to Adjustments Under This Section.
              ------------------------------------------ ------------------  
The following provisions shall be applicable to the making of adjustments in the
Conversion Price hereinbefore provided in this Section:

               (1)  Computation of Consideration.
                    ---------------------------- 

               (i) To the extent that any additional shares of Common Stock
     shall be issued for cash, the consideration therefor shall be deemed to be
     the amount of the cash received by the Company therefor.

               (ii)  The consideration for any additional shares of Common Stock
     issuable pursuant to any warrants, options or other rights to subscribe for
     or purchase the same shall be the consideration received by the Company for
     issuing such warrants, options or other rights, plus the minimum additional
     consideration payable to the Company upon the exercise of such warrants,
     options or other rights.

               (iii)  The consideration for any additional shares of Common
     Stock issuable pursuant to the terms of any convertible securities shall be
     the

     consideration received by the Company for issuing any warrants, options or
     other rights to subscribe for or purchase such convertible securities, plus
     the consideration paid or payable to the Company in respect of the
     subscription for or purchase of such convertible securities, plus the
     minimum additional consideration, if any, payable to the Company upon the
     exercise of the right of conversion or exchange in such convertible
     securities.

               (iv)  Consideration received from an issuance referred to in
     clauses (i), (ii) and (iii) above shall be exclusive of any amounts paid or
     receivable for accrued interest or accrued dividends and without deduction
     of any compensation, discounts or expenses paid or incurred by the Company
     for and in the underwriting of, or otherwise in connection with, any such
     issuance.  To the extent that any such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the amount of such consideration shall be deemed to be the fair
     market value of such consideration at the time of such issuance as
     determined in good faith by the board of directors.  In case of the
     issuance at any time of any additional shares of Common Stock or
     convertible

                                      27

     securities in payment or satisfaction of any dividend upon any class of
     stock other than Common Stock, the Company shall be deemed to have received
     for such additional shares of Common Stock or convertible securities a
     consideration equal to the amount of such dividend so paid or satisfied.

               (2) Readjustment of Conversion Price.  Upon the expiration of the
                   --------------------------------                             
     right to convert or exchange any convertible securities, or upon the
     expiration of any rights, options or warrants, if any such convertible
     securities shall not have been converted or exchanged, or if any such
     rights, options or warrants shall not have been exercised, the number of
     shares of Common Stock deemed to be issued and outstanding by reason of the
     fact that they were issuable upon conversion or exchange of any such
     convertible securities or upon exercise of any such rights, options or
     warrants shall no longer be deemed to have been issued and outstanding, and
     the Conversion Price shall forthwith be readjusted and thereafter be the
     price which it would have been (but not reflecting any other adjustments in
     the Conversion Price made pursuant to the provisions of this Section 4
     after the issuance of such convertible securities, rights, options or

                                      28
<PAGE>
 
     warrants) had the adjustment of the Conversion Price made upon the issuance
     or sale of such convertible securities or the issuance of such rights,
     options or warrants been made on the basis of the issuance only of the
     number of additional shares of Common Stock actually issued upon conversion
     or exchange of such convertible securities or upon the exercise of such
     rights, options or warrants, and thereupon only the number of additional
     shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Company
     (computed in subsection 4(h)(1) hereof) shall be deemed to have been
     received by the Company.

          (i) Notice of Adjustments.  Whenever either Conversion Price shall be
              ---------------------                                            
adjusted pursuant to this Section 4, the Company shall promptly prepare a
certificate signed by the president and the chief financial officer of the
Company setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the board of directors made any
determination hereunder) and the applicable Conversion Price after giving effect
to such adjustment, and shall promptly cause copies of such certificate to be
mailed

                                      29

B Preferred Stock.

          (j) Definition.  For the purpose hereof, the term "convertible

     outstanding shares of Common Stock plus the aggregate number of shares of
     Common Stock which would be outstanding upon (X) conversion of

                                      30

     5.  Preference on Liquidation.
         ------------------------- 

          (a) Liquidation, Dissolution or Winding Up of Company.  In the event
              -------------------------------------------------               
of any liquidation, dissolution or winding up of the Company, the holders of
shares of Series A Preferred Stock then outstanding shall be entitled to be paid
an amount equal to $.3617 per share, and the holders of shares, of Series B
Preferred Stock shall be entitled to be paid an amount equal to $1.2307 per
share, (subject, in each case, to appropriate adjustment for subdivisions and
combinations), plus declared and unpaid dividends thereon to the date fixed for
distribution, out of the assets of the Company available for distribution to its
stockholders, whether from capital, surplus or earnings, after full payment of
the liquidation preference to the holders of

                                      31
<PAGE>
 
shares of Serial Preferred Stock, if any, which have a preference or priority
upon dissolution of the Company over the Series A or B Preferred Stock and
before any payment shall be made in respect to the Company's junior stock.
After full payment of the liquidation preference to the holders of shares of
Series A Preferred Stock then outstanding and to the holders of Series B
Preferred Stock then outstanding and to the holders of shares of Serial
Preferred Stock, if any, which have preference or priority upon dissolution of
the Company over Series A, B and C Preferred Stock, the holders of shares of
Series C Preferred Stock shall be entitled to be paid an amount equal to $4.00
per share (subject to appropriate adjustment for subdivisions and combinations),
out of the assets of the Company available for distribution to its stockholders,

respect to the Company's Common Stock or any other class or series of capital
stock of the Company hereafter authorized over which the Series C Preferred
Stock shall have preference or priority upon the dissolution of, or the
distribution of assets of, the Company.  If upon any liquidation, dissolution or
winding up of the Company, the assets of the Company available for distribution
to its stockholders shall be insufficient to pay the holders of

                                      32
<PAGE>
 
shares of Series A or B Preferred Stock the full amounts to which they shall be
entitled, the holders of shares of Series A or B Preferred Stock and any parity
stock shall share ratably in any distribution of assets (after payment of any
amounts due in respect of any senior stock (which for purposes of this Article
shall mean any class or series of capital stock of the Company hereafter
authorized which shall have preference or priority over the Series A and B
Preferred Stock and any parity stock upon the dissolution of, or the
distribution of the assets of, the Company)) according to the respective amounts
which would be payable in respect of the shares held by them upon such
distribution if all amounts payable on or with respect to said shares were paid
in full.  If upon any liquidation, dissolution or winding up of the Company, the
assets of the Company available for distribution to its stockholders shall be
insufficient to pay the holders of Series C Preferred Stock the full amounts to
which they shall be entitled, the holders of shares of Series C Preferred Stock
shall share ratably in any distribution of assets, after payment of any amounts
due in respect of Series A or B Preferred Stock or any senior stock, according
to the respective amounts which would be payable in respect of the shares held
by them upon

                                      33
<PAGE>
 
such distribution if all amounts payable on or with respect to said shares were
paid in full.

          (b) Notice.  If the Company shall propose to take any action of the
              ------                                                         
types described in Section 5(a), subsection 3(c) or in subsection 4(e) hereof,
then the Company shall cause to be mailed to the Transfer Agent and to the
holders of record of the outstanding shares of Series A, B or C Preferred Stock,
at least 20 days prior to the applicable record date hereinafter specified, a
notice describing the material terms and conditions of such proposed action,
including a description of the stock, cash and property to be received by the
holders of the Company's capital stock upon consummation of the proposed action,
and stating (i) the date on which a record is to be taken for the purpose of
distributing such stock, cash and property or, if a record is not to be taken,
the date as of which the holders of the Company's capital stock of record to be
entitled to share in such distribution are to be determined or (ii) the date on
which such proposed action is expected to become effective and the date as of
which it is expected to become effective, and the date as of which it is
expected that holders of record of the Company's capital stock shall be entitled
to exchange their shares of capital stock for securities or other property
deliverable upon consummation of such

                                      34
<PAGE>
 
proposed action.  If any material change in the facts set forth in the initial
notice shall occur, the Company shall promptly give written notice to each
holder of shares of Series A, B or C Preferred Stock of such material change.

          (c) Waiting Period.  The Company shall not consummate any proposed
              --------------

              ----------------------------------                               
to take any action of the types described above in Section 5(a), subsection 3(c)
or in subsection 4(e) hereof which will involve the distribution of assets other
than cash, the Company shall promptly engage independent competent appraisers
(who shall be approved by the holders of 66-2/3% of the Series A and B Preferred
Stock then outstanding, which approval shall not unreasonably be withheld) to
determine the value of the assets to be distributed.  The Company shall, upon
receipt of such appraiser's valuation, give prompt written notice to each holder
of shares of the Series A, B or C Preferred Stock of (i) the appraiser's
valuation, and (ii) the Company's

                                      35
<PAGE>
 
valuation, which valuation shall not be greater than that given by the
appraiser.

     6.  Voting.
         ------ 

          (a) One Class.  Except as otherwise provided herein or as required by
              ---------                                                        
law, the holders of shares of the Series A, B or C Preferred Stock and the
holders of shares of the Company's Common Stock shall vote together as one class
on all matters.  The holders of shares of Series C Preferred Stock shall have
the same voting rights as holders of shares of the Company's Common Stock.

          (b) Number of Votes for Preferred Stock.  At every meeting of
              -----------------------------------                      
stockholders of the company, each holder of shares of the Series A or B
Preferred Stock shall be entitled to as many votes as are represented by the
number of shares of the Common Stock into which such holder's shares of the
Series A or B Preferred Stock are then convertible (the total number of such
shares of all such holders being hereinafter referred to as the "Convertible
Common Shares").

          (c) Vote of Series A or B Preferred Stock.  Except as otherwise
              -------------------------------------                      
provided by law, the holders of shares of Series A and B Preferred Stock, when
voting as a class, shall act by the vote of 66-2/3% of the shares of Series A
and B Preferred Stock outstanding on the record date for

                                      36
<PAGE>
 
such vote, provided, however, that the provisions of this Article FOURTH shall
not be amended except by the unanimous vote or unanimous written consent of the
holders of Series A and B Preferred Stock then outstanding.

     7.   Reservation of Common Stock.  The Company shall, at all times when the
          ---------------------------                                           
Series A, B or C Preferred Stock shall be outstanding, reserve and keep
available out of its authorized but unissued stock, for the purpose of effecting
the conversion of the Series A, B or C Preferred Stock, such number of its duly
authorized shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding Series A, B or C Preferred Stock.
Before taking any action which would cause an adjustment reducing the Conversion
Price below the then par value of the shares of Common Stock issuable upon
conversion of the Series A or B Preferred Stock, the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and nonassessable
shares of such Common Stock at such adjusted Conversion Price.

     8.  Series C Preferred Stock Anti-Dilution Right.  If the Company
         --------------------------------------------                 
shall make any public or private offering of its stock (other than an offering
of securities issuable pursuant to an employee stock option or other
compensation

                                      37
<PAGE>
 
plan, including, but not limited to, a Junior Common Stock Plan for employees,
and other than an offering of Common Stock to be issued pursuant to the Non-
Qualified Stock Option Plan approved by the Board of Directors and shareholders
of the Company), the holders of the shares of Series C Preferred Stock shall
have the right, at their election, to purchase such additional shares of the
class of stock offered by the Company as shall maintain their percentage equity
share of the Company at the same level as before such offering.  Any purchase of
additional shares pursuant to this Section shall be at the same price and on the
same terms and conditions upon which the offering is made, and shall be
subsequent to any purchase of such shares by the holders of Series A or B
Preferred Stock pursuant to their right of first refusal contained in Section
10.12 of the Convertible Preferred Stock Purchase Agreement dated as of November
12, 1982."

such holder at such holder's address as the same shall appear on the books of
the Company.  Such notice shall (a) if given pursuant to Section 2.1(a), state

(d) if such redemption is pursuant to Section 2.1(a), call upon such holder to

some or all of his shares at the place designated in such notice. if less than
all of the outstanding shares of Preferred Stock are to be redeemed pursuant to
Section 2.1(a), or less than all of the shares of Preferred Stock as to which
redemption has been duly requested are to be redeemed pursuant to Section
2.1(b), the shares of each holder to be redeemed shall be determined pro rata
                                                                     --- ----
based upon the proportion which (i) the sum of the number of shares of Preferred
Stock and

                                       7
<PAGE>
 
Preferred Stock Equivalents (as defined below) then held by each holder bears to
(ii) the aggregate number of shares of Preferred Stock and Preferred Stock
Equivalents then held by all such holders immediately prior to such redemption.

any Common Stock issued upon conversion of a share of Preferred Stock or any
Common Stock or other security issued in exchange for or in replacement of a
share of Preferred Stock or Preferred Stock Equivalent, and for purposes of any
computation or vote involving such Preferred Stock Equivalents provided for

share of Preferred Stock shall be deemed the equivalent of one share of
Preferred Stock.  On or after the date fixed in such notice of redemption in the
case of redemption pursuant to Section 2.1(a), or at any time following receipt
of such notice of redemption in the case of redemption pursuant to Section
2.1(b), each holder of shares of Preferred Stock to be so redeemed shall present
and surrender the certificate or certificates for such shares to the Company at
the place designated in said notice and thereupon the redemption price of such
shares shall be paid to, or to the order of, the person whose name appears on
such certificate or certificates as the owner thereof.

From and after the date fixed in any such notice as the day of redemption,
unless default shall be made by the Company in providing for the payment of the
redemption price pursuant to such notice, all dividends on the Preferred Stock
thereby called for redemption pursuant to Section 2.1(a) hereof shall cease to
accrue and all rights of the holders thereof as shareholders of the Company,
except the right to receive the redemption price (but without interest thereon),
shall cease and terminate, provided, however, that the Company shall deposit the
amount required for the payment of any part of the redemption price not claimed
on the redemption date with a bank or trust company doing business in the State
of New York and having a capital and surplus of at least $250,000,000.  Any
interest allowed on moneys so deposited which shall remain unclaimed by the
holders of the Preferred Stock at the end of six years after the redemption date
shall be paid by such bank or trust company to the Company, but the Company
shall remain obligated to make payment thereof to the holders of Preferred Stock
entitled thereto (subject to any applicable escheat or similar laws).  Any
shares of Preferred Stock redeemed by the Company pursuant to either Section
2.1(a) or Section 2.1(b) shall be retired and shall not be reissued and the
Company may from time to time take such appropriate

                                       9

corporate action as may be necessary to reduce the authorized

Preferred Stock.

          2.3. Transfer Books.  In order to facilitate the redemption of any
               --------------                                               
shares of Preferred Stock, the Board of Directors of the Company is authorized

shares to be redeemed.

          2.4. Events of Default.  For purposes of this Section 2, an Event of
               -----------------                                              
Default under this [Article) shall be deemed to have occurred (i) if dividends
accrued on, or amounts required to be paid in redemption of, the Preferred Stock
are not paid by the Company when due; (ii) if the Company or any of its
subsidiaries shall (a) admit in writing its inability to pay its debts generally
as they become due, (b) file a petition or answer or consent seeking relief
under the Federal Bankruptcy Code, as now constituted or hereafter amended, or
any other applicable Federal or state bankruptcy or insolvency law or other
similar law, (c) consent to the institution of proceedings under any law listed
in (b) above, or to the filing of any such petition or to the appointment or
taking possession of a receiver, liquidator, assignee, trustee, custodian (or
other similar official) of the Company or any such subsidiary or of any
substantial part of their property, or (d) make an

                                      10

assignment for the benefit of its creditors; (iii) if a decree or order shall be
entered by a court for relief in respect of the Company or any of its
subsidiaries under the Federal Bankruptcy Code, as now constituted or hereafter
amended, or any other applicable Federal or state bankruptcy or insolvency law
or other similar law, or appointing a receiver, liquidator, assignee, trustee
(or similar official) of the Company or any such subsidiary or of any
substantial part of their property or ordering the winding-up or liquidation of
their affairs and such decree or order shall not be vacated or set aside or
stayed within a period of 30 days from the date of entry thereof; (iv) if the
Company wilfully ails in any material respect to perform or observe any material
agreement, covenant or obligation set forth in the Convertible Preferred Stock
Purchase Agreement dated as of November 12, 1982 among the Company, The Liposome
Company, a New Jersey limited partnership, and certain purchasers of the
Company's Preferred Stock; or (v) if default in the observance of the covenant
set forth in Section 10.5 of said Purchase Agreement shall have occurred and be
continuing.

          3.   Conversion Rights.  The holders of shares of Preferred Stock
               -----------------                                           
shall have the right, at their option, to

                                      11
<PAGE>
 
convert such shares into shares of Common Stock at any time on and subject to
the following terms and conditions:

          (a) Conversion Price.  Each share of the Preferred Stock shall be
              ----------------                                             
convertible at the office of the Company, or at the office of the transfer
agent, if any, for the Preferred Stock, into such number of fully paid and
nonassessable shares of Common Stock as shall equal the quotient of (i) in the
case of the Series A Preferred Stock, $.7234 divided by the Series A Conversion
Price, determined as hereinafter provided, in effect at the time of conversion
and (ii) in the case of the Series B Preferred Stock, $1.2307 divided by the
Series B Conversion Price, determined as hereinafter provided, in effect at the
time of conversion.  The price at which shares of Common Stock shall be
deliverable upon conversion of the Series A Preferred Stock (the "Series A
Conversion Price") shall initially be $.7234 and the price at which shares of
Common Stock shall be deliverable upon conversion of the Series B Preferred
Stock (the "Series B Conversion Price") shall initially be $ 1.2307. Such
Conversion Prices shall be adjusted in certain instances as provided below in
Section 4.

          (b) Dividends.  Payment or adjustment shall be made upon any
              ---------                                               
conversion on account of any dividends declared but not yet paid on the shares
of Preferred Stock

                                      12
<PAGE>
 
surrendered for conversion or on account of any dividends declared but not yet
paid on the Common Stock issued upon such conversion.

          (c) Conversion of Preferred Stock.  In order to convert shares of
              -----------------------------                                
Preferred Stock into Common Stock, the holder thereof shall surrender the
certificate or certificates therefor at the office of the Company or of the
transfer agent hereinabove mentioned, and shall give written notice to the
Company therewith that he elects to convert such shares.  If any holder of
shares of Preferred Stock shall desire to have the certificate or certificates
for shares of Common Stock issued in a name or names other than the name or
names of the holder or holders of record of such shares of Preferred Stock, such
certificate or certificates shall be duly endorsed to the transferee or in blank
or shall be accompanied by a proper instrument or instruments of assignment to
such transferee or in blank; such certificate or certificates shall also be
accompanied by proof of payment of any applicable transfer taxes.  Shares of
Preferred Stock shall be deemed to have been converted immediately prior to the
close of business on the date of the surrender of such shares for conversion as
provided above ("Conversion Date"), and the person or persons entitled to
receive the Common Stock issuable upon such

                                      13
<PAGE>
 
conversion shall be treated for all purposes as the record holder or holders of
such Common Stock on the Conversion Date.  As promptly as practicable on or
after the Conversion Date, the Company will issue and deliver, at the office at
which such surrender is made, (i) a certificate or certificates for the number
of full shares of Common Stock issuable upon such conversion, together with an
appropriate portion of the applicable Conversion Price in cash in lieu of any
fraction of a share and (ii) a new certificate or certificates for the numbers
of shares of Preferred Stock, if any, represented by the certificate or
certificates surrendered but not converted, to the person or persons entitled to
receive the same.

          (d) Cancellation of Preferred Stock.  All shares of Preferred Stock
              -------------------------------                                
which shall have been surrendered for conversion as herein provided shall no
longer be deemed to be outstanding and all rights with respect to such shares,
including the rights, if any, to receive notices and to vote, shall forthwith
cease and terminate except only the right of the holders thereof to receive
shares of Common Stock in exchange therefor and payment of any accrued and
unpaid dividends thereon, provided, however, that the provisions of this Section
3(d) shall not affect any rights which holders of Preferred Stock may enjoy
under any

                                      14
<PAGE>
 
separate instrument or agreement pursuant to which such Preferred Stock is
issued or sold.  Any shares of Preferred Stock so converted shall be retired and
cancelled and shall not be reissued.

          4.   Adjustment of Conversion Prices.  The Series B Conversion Price
               -------------------------------                                
and (subject to subsection 4(g) hereof) the Series A Conversion Price from time
to time in effect shall be subject to adjustment (to the nearest tenth of a
cent) from time to time as follows:

          (a) Stock Dividends, Subdivisions and Combinations.  If the Company
              ----------------------------------------------                 
shall:
          (1) declare a dividend payable in, or a distribution of, Common Stock,
     to the holders of any other class or series of the Company's capital stock,
     or

          (2) subdivide its outstanding shares of Common Stock into a larger
     number of shares of Common Stock, or

          (3) combine its outstanding shares of Common Stock into a smaller
     number of shares of Common Stock,

then each Conversion Price shall be adjusted to that price determined by
multiplying such Conversion Price by a fraction (i) the numerator of which shall
be the total number of outstanding shares of Common Stock immediately prior to
such event, and (ii) the denominator of which shall

                                      15
<PAGE>
 
be the total number of outstanding shares of Common Stock immediately after such
event.

          (b) Issuance of Additional Shares of Common Stock.  If the Company
              ---------------------------------------------                 
shall (except as hereinafter provided) issue any additional shares of Common
Stock (whether original issuance or out of treasury shares) for a consideration
per share less than either Conversion Price, then such Conversion Price upon
each such issuance shall be adjusted to that price determined by multiplying
such Conversion Price by a fraction:

          (1) the numerator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares of Common Stock plus the quotient resulting from dividing the
     aggregate consideration received for such additional shares of Common Stock
     by the Conversion Price (as in effect immediately prior to the adjustment
     provided for herein) and

          (2) the denominator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares of Common Stock, plus the number of such additional shares of Common
     Stock so issued.

          The provisions of this subsection shall not apply


                                      16
<PAGE>
 
to any additional shares of Common Stock which are distributed to holders of the
Company's capital stock as a stock dividend, for which an adjustment is provided
for under subsection (a) of this Section.  No adjustment of the Conversion Price
shall be made under this subsection upon the issuance of any additional shares
of Common Stock which are issued pursuant to the exercise of any warrants,
options, or other subscription or purchase rights or pursuant to the exercise of
any conversion or exchange rights in any convertible securities, if any such
adjustment shall previously have been made upon the issuance of such warrants,
options or other rights or upon the issuance of such convertible securities (or
upon the issuance of any warrants, options or other rights therefor) pursuant to
subsection (c) of this Section.

          (c) Issuance of Warrants, Options, Other Rights or Convertible
              ------------------------------------------- --------------
Securities.  In case the Company shall issue any warrants, options or other
- ----------                                                                 
rights to subscribe for or purchase (i) any additional shares of Common Stock or
(ii) any convertible securities, or in case the Company shall issue any
convertible securities, and, in either such case, the consideration per share
for which additional shares of Common Stock may at any time thereafter be
issuable pursuant to such warrants, options or other rights or pursuant to the

                                      17
<PAGE>
 
terms of such convertible securities shall be less than the Conversion Price,
then the Conversion Price upon each such issuance shall be adjusted to that
price determined by multiplying the Conversion Price by a fraction:

          (1) the numerator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such warrants,
     options or other rights, or such convertible securities, plus the quotient
     resulting from dividing the aggregate consideration received in respect of
     additional shares of Common Stock issuable pursuant to such rights or upon
     conversion of such convertible securities (equal to the aggregate
     consideration received for such rights or convertible securities plus the
     aggregate additional consideration, if any, required to exercise such
     rights or convert such securities) by the Conversion Price (as in effect
     immediately prior to the adjustment provided for herein) and

          (2) the denominator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares of Common Stock, plus the maximum number of additional shares of
     Common Stock issuable pursuant to all such warrants, options or other
     rights or necessary to effect the

                                      18
<PAGE>
 
     conversion or exchange of all such convertible securities.

          (d) Change in Warrants, Options, Other Rights or Convertible
              --------------------------------------------------------
Securities.  Upon any change in the number of shares of Common Stock deliverable
- ----------                                                                      
upon the exercise of any warrants, options, other rights or convertible
securities covered in subsection 4(c), or upon any change in the minimum
purchase price of such warrants, options, rights or convertible securities,
other than a change resulting from the antidilution provisions of such warrants,
options, rights or convertible securities, the Conversion Price shall forthwith
be readjusted to such Conversion Price as would have obtained had the adjustment
made upon the issuance of such warrants, options, rights or convertible
securities not exercised, converted or exchanged prior to such change been made
upon the basis of such change; provided, however, that no readjustment pursuant
to the terms of this subsection 4(d) shall have the effect of increasing the
Conversion Price to an amount which exceeds the initial Conversion Price set
forth in subsection 3(a) or as such Conversion Price shall have been adjusted
pursuant to subsection 4(a).

          (e) Mergers and Consolidations.  In case of any merger, consolidation
              --------------------------                                       
or reorganization of the Company into or with any other corporation, a merger of
any other

                                      19
<PAGE>
 
corporation into the Company, or a sale, lease, mortgage, pledge, exchange,
transfer or other disposition by the Company of all or substantially all of its
assets, or any reclassification of the stock of the Company (other than a change
in par value or from no par value to par value or from par value to no par
value, or as a result of a stock dividend or subdivision or a combination of
shares), each share of Preferred Stock shall thereafter be convertible into the
number of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock deliverable upon conversion of such
Preferred Stock would have been entitled upon such consolidation, merger,
disposition or reclassification; and, in any such case, appropriate adjustment
(as determined in good faith by the board of directors) shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of the holders of the Preferred Stock, to the end that the
provisions set forth herein (including provisions with respect to adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property there after
deliverable upon the conversion of the Preferred Stock.

                                      20
<PAGE>
 
          (f) Alternative Adjustment.  Notwithstanding the foregoing, at such

time as adjustment of the Conversion Price shall have been required hereunder in
respect of shares of Common Stock or convertible securities or warrants, options
or other rights to subscribe for or purchase shares of Common Stock or
convertible securities, representing an aggregate of at least 20% of the
difference between (i) the number of shares of Common Stock outstanding
(assuming conversion of the Preferred Stock and any other convertible securities
then outstanding) immediately prior to the event first requiring adjustment
pursuant to this subsection 4(f) and (ii) the number of shares of Common Stock
in respect of which such adjustment has theretofore been required, the
Conversion Price shall thereafter be adjusted, in the case of any event
requiring adjustment of the Conversion Price pursuant to subsections 4(b) or
4(c) above, to such lower price as shall equal the consideration per share for
which shares of Common Stock were issued in, or are issuable as a result of,
such event.

          (g) Series A Adjustments.  Prior to November 12, 1984, the Series A
              --------------------                                           
Conversion Price shall be adjusted, if necessary, as provided in subsections

in lieu of further adjustments pursuant to the foregoing

<PAGE>
 
subsections 4(a)-4(f), upon the occurrence of any event requiring adjustment of
the Series B Conversion Price pursuant to this Section 4, to that price
determined by multiplying the Series A Conversion Price by a fraction, the
numerator of which shall be the new Series B Conversion Price resulting from
such adjustment of the Series B Conversion Price and the denominator of which
shall be the Series B Conversion Price in effect immediately prior to such
adjustment of the Series B Conversion Price.

          (h) Other Provisions Applicable to Adjustments Under This Section.
              ------------------------------------------ ------------------  
The following provisions shall be applicable to the making of adjustments in the
Conversion Price hereinbefore provided in this Section:

          (1)  Computation of Consideration.
               ---------------------------- 

               (i) To the extent that any additional shares of Common Stock
          shall be issued for cash, the consideration therefor shall be deemed
          to be the amount of the cash received by the Company therefor.

               (ii)  The consideration for any additional shares of Common Stock
          issuable pursuant to any warrants, options or other rights to
          subscribe for or purchase the same shall be the consideration received
          by the Company for issuing such warrants,

                                      22
<PAGE>
 
          options or other rights, plus the minimum additional consideration
          payable to the Company upon the exercise of such warrants, options or
          other rights.

               (iii)  The consideration for any additional shares of Common
          Stock issuable pursuant to the terms of any convertible securities
          shall be the consideration received by the Company for issuing any
          warrants, options or other rights to subscribe for or purchase such
          convertible securities, plus the consideration paid or payable to the
          Company in respect of the subscription for or purchase of such
          convertible securities, plus the minimum additional consideration, if
          any, payable to the Company upon the exercise of the right of
          conversion or exchange in such convertible securities.

               (iv)  Consideration received from an issuance referred to in
          clauses (i), (ii) and (iii) above shall be exclusive of any amounts
          paid or receivable for accrued interest or accrued dividends and
          without deduction of any compensation, discounts or expenses paid or
          incurred by the Company for and in the

                                      23
<PAGE>
 
          underwriting of, or otherwise in connection with, any such issuance.
          To the extent that any such issuance shall be for a consideration
          other than cash, then, except as herein otherwise expressly provided,
          the amount of such consideration shall be deemed to be the fair market
          value of such consideration at the time of such issuance as determined
          in good faith by the board of directors.  In case of the issuance at
          any time of any additional shares of Common Stock or convertible
          securities in payment or satisfaction of any dividend upon any class
          of stock other than Common Stock, the Company shall be deemed to have
          received for such additional shares of Common Stock or convertible
          securities a consideration equal to the amount of such dividend so
          paid or satisfied.

          (2) Readjustment of Conversion Price.  Upon the expiration of the
              --------------------------------                             
     right to convert or exchange any convertible securities, or upon the
     expiration of any rights, options or warrants, if any such convertible
     securities shall not have been converted or exchanged, or if any such
     rights, options or warrants shall not have been exercised, the number of
     shares of Common

                                      24
<PAGE>
 
     Stock deemed to be issued and outstanding by reason of the fact that they
     were issuable upon conversion or exchange of any such convertible
     securities or upon exercise of any such rights, options or warrants shall
     no longer be deemed to have been issued and outstanding, and the Conversion
     Price shall forthwith be readjusted and thereafter be the price which it
     would have been (but not reflecting any other adjustments in the Conversion
     Price made pursuant to the provisions of this Section 4 after the issuance
     of such convertible securities, rights, options or warrants) had the
     adjustment of the Conversion Price made upon the issuance or sale of such
     convertible securities or the issuance of such rights, options or warrants
     been made on the basis of the issuance only of the number of additional
     shares of Common Stock actually issued upon conversion or exchange of such
     convertible securities or upon the exercise of such rights, options or
     warrants, and thereupon only the number of additional shares of Common
     Stock actually so issued shall be deemed to have been issued and only the
     consideration actually received by the Company (computed in subsection
     4(h)(1) hereof) shall be deemed to have been received by the Company.

                                      25
<PAGE>
 
          (i) Notice of Adjustments.  Whenever either Conversion Price shall be
              ---------------------                                            
adjusted pursuant to this Section 4, the Company shall promptly prepare a
certificate signed by the president and the chief financial officer of the
Company setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the board of directors made any
determination hereunder) and the applicable Conversion Price after giving effect
to such adjustment, and shall promptly cause copies of such certificate to be
mailed (by first class mail postage prepaid) to each of the holders of the
Preferred Stock.

          (j) Definition.  For the purposes hereof, the term "convertible
              ----------                                                 
securities" shall mean evidences of indebtedness, shares of stock or other
securities which are convertible into or exchangeable for additional shares of
Common Stock, either immediately or upon a specified date or upon the happening
of a specified event.

          (k) Exceptions to Adjustment of Conversion Price.  The provisions of
              --------------------------------------------

securities by the Company:

<PAGE>
 
          (1) issuances pursuant to conversion of the Preferred Stock; and

          (2) grants to or exercises of stock options to purchase Common Stock
     by employees; provided that the aggregate number of shares of Common Stock
     issued or issuable to such employees pursuant to this subsection 4(k)(2)
     shall not exceed 5% of the sum of the aggregate number of outstanding
     shares of Common Stock plus the aggregate number of shares of Common Stock
     which would be outstanding upon (X) conversion of all outstanding shares of
     Preferred Stock, (Y) exercise of all outstanding warrants, options or other
     rights to subscribe for or purchase shares of Common Stock and (Z)
     conversion or exchange of all outstanding convertible securities.

          5.   Preference on Liquidation.
               ------------------------- 

          (a) Liquidation, Dissolution or Winding Up of Company.  In the event
              -------------------------------------------------               
of any liquidation, dissolution or winding up of the Company, the holders of
shares of Series A Preferred Stock then outstanding shall be entitled to be paid
an amount equal to $.3617 per share, and the holders of shares of Series B
Preferred Stock shall be entitled to be paid an amount equal to $1.2307 per
share, (subject, in each case, to appropriate adjustment for subdivisions and


                                      27
<PAGE>
 
combinations), plus declared and unpaid dividends thereon to the date fixed for
distribution, out of the assets of the Company available for distribution to its
stockholders, whether from capital, surplus or earnings, before any payment
shall be made in respect to the Company's junior stock.  If upon any
liquidation, dissolution or winding up of the Company, the assets of the Company
available for distribution to its stockholders shall be insufficient to pay the
holders of shares of Preferred Stock the full amounts to which they shall be
entitled, the holders of shares of Preferred Stock and any parity stock shall
share ratably in any distribution of assets (after payment of any amounts due in
respect of any senior stock (which for purposes of this Article shall mean any
class or series of capital stock of the Company hereafter authorized which shall
have preference or priority over the Preferred Stock and any parity stock upon
the dissolution of, or the distribution of the assets of, the Company))
according to the respective amounts which would be payable in respect of the
shares held by them upon such distribution if all amounts payable on or with
respect to said shares were paid in full.

          (b) Notice.  If the Company shall propose to take any action of the
              ------                                                         
types described in Section 5(a) or in

                                      28
<PAGE>
 
subsection 4(e) hereof, then the Company shall cause to be mailed to the
Transfer Agent and to the holders of record of the outstanding shares of
Preferred Stock, at least 20 days prior to the applicable record date
hereinafter specified, a notice describing the material terms and conditions of
such proposed action, including a description of the stock, cash and property to
be received by the holders of the Company's capital stock upon consummation of
the proposed action, and stating (i) the date on which a record is to be taken
for the purpose of distributing such stock, cash and property or, if a record is
not to be taken, the date as of which the holders of the Company's capital stock
of record to be entitled to share in such distribution are to be determined or
(ii) the date on which such proposed action is expected to become effective and
the date as of which it is expected to become effective, and the date as of
which it is expected that holders of record of the Company's capital stock shall
be entitled to exchange their shares of capital stock for securities or other
property deliverable upon consummation of such proposed action.  If any material
change in the facts set forth in the initial notice shall occur, the Company
shall promptly give written notice to each holder of shares of Preferred Stock
of such material change.

                                      29

          (c) Waiting Period.  The Company shall not consummate any proposed
              --------------                                                
action of the types described above in Section 5(a) or in subsection 4(e) hereof
before the expiration of forty-five days after the mailing of the initial notice
thereof or fifteen days after the mailing of any subsequent written notice,
whichever is later.

          (d) Appraisal of Non-Cash Distribution.  If the Company shall propose
              ----------------------------------                               
to take any action of the types described above in Section 5(a) or in subsection
4(e) hereof which will involve the distribution of assets other than cash, the
Company shall promptly engage independent competent appraisers (who shall be
approved by the holders of 66-2/3% of the Preferred Stock then outstanding,
which approval shall not unreasonably be withheld) to determine the value of the
assets to be distributed.  The Company shall, upon receipt of such appraiser's
valuation, give prompt written notice to each holder of shares of the Preferred
Stock of (i) the appraiser's valuation, and (ii) the Company's valuation, which
valuation shall not be greater than that given by the appraiser.

          6.  Voting.
              ------ 
          (a) One Class.  Except as otherwise provided herein or as required by
              ---------                                                        
law, the holders of shares of the Preferred Stock and the holders of shares of
the Company's

                                      30
<PAGE>
 
Common Stock shall vote together as one class on all matters.

          (b) Number of Votes for Preferred Stock.  At every meeting of
              -----------------------------------                      
stockholders of the Company, each holder of shares of the Preferred Stock shall
be entitled to as many votes as are represented by the number of shares of the
Common Stock into which such holder's shares of the Preferred Stock are then
convertible (the total number of such shares of all such holders being
hereinafter referred to as the "Convertible Common Shares").

          (c) Vote of Preferred Stock.  Except as otherwise provided by law, the
              -----------------------                                           
holders of shares of Preferred Stock, when voting as a class, shall act by the
vote of 66-2/3% of the shares of Preferred Stock outstanding on the record date
for such vote, provided, however, that the provisions of this Article FOURTH
shall not be amended except by the unanimous vote or unanimous written consent
of the holders of Preferred Stock then outstanding.

          7.   Reservation of Common Stock.  The Company shall, at all times
               ---------------------------                                  
when the Preferred Stock shall be outstanding, reserve and keep available out of
its authorized but unissued stock, for the purpose of effecting the conversion
of the Preferred Stock, such number of its duly authorized shares of Common
Stock as shall from time to

                                      31
<PAGE>
 
time be sufficient to effect the conversion of all outstanding Preferred Stock.
Before taking any action which would cause an adjustment reducing the Conversion
Price below the then par value of the shares of Common Stock issuable upon
conversion of the Preferred Stock, the Company will take any corporate action
which may, in the opinion of its counsel, be necessary in order that the Company
may validly and legally issue fully paid and nonassessable shares of such Common
Stock at such adjusted Conversion Price.

                              SUPPLY OF PRODUCTS
                              ------------------

   2.1   Supply of Product.  During the term of this Agreement, BMS shall
         -----------------                                               
manufacture and sell to TLC, and TLC may purchase from BMS, Bulk Amphotericin B
pursuant to purchase orders submitted by TLC to BMS from time to time in
accordance with Section 2.3; provided, however, that BMS's obligation to supply
                             --------  -------                                 
TLC with the Product may be subject to delay or interruptions resulting from
BMS's sourcing, or the unavailability, of crude amphotericin B from third
parties.

   2.2   Purchase Price.
         -------------- 

         (a)  It is the parties' intent that the purchase price payable by TLC
for the Product be equal to the lower of (A) ____% of BMS's Manufacturing Cost
thereof and (B) if applicable, the lowest price contemporaneously charged by BMS
to any non-Affiliate third party for Bulk Amphotericin B supplied by BMS under
reasonably comparable terms and conditions.  Accordingly, all determinations of
the actual purchase price for the Product, and any adjustments thereto, shall be
made on such basis.  For shipments to be delivered on or prior to December 31,
1994, the

                                       4
<PAGE>
 
purchase price for the Product shall be $________ per base kilogram. For each
calendar year thereafter, BMS shall, not later than October 31 of the preceding
year, notify TLC in writing of the purchase price for the Product to be
delivered during such calendar year.

         (b)  BMS shall, upon written request by TLC, advise TLC of the
anticipated Manufacturing Cost of the Product; provided, however, that BMS shall
                                               --------  -------                
not be required to do so more frequently than once in any calendar year.  TLC
shall have the right to request reasonable documentation of BMS's Manufacturing
Cost calculations and to request discussion of such calculations with
appropriate representatives of BMS.  Upon TLC's reasonable request, BMS shall
disclose to TLC data and information in support of BMS's Manufacturing Cost.

         (c)  Either party may, whether or not the purchase order in question
has been submitted to, or accepted by, BMS, request an adjustment to any
purchase price otherwise applicable pursuant to Section 2.2(a), but only if the
party initiating discussion has reasonable basis to believe that the then
prevailing price may be unreasonably high or low given the relevant facts and
circumstances.  Following any request pursuant to the foregoing, the parties
shall promptly discuss in good faith with a view to agreeing on an adjustment,
if any, in order to give effect to the provisions of the first two sentences of
Section 2.2(a).  Notwithstanding the foregoing, no adjustment of any purchase
price shall be made with respect to any shipment unless the adjustment request
is received by the party receiving 

                                       5
<PAGE>
 
the request at least 30 days prior to the specified delivery date.

         (d)  In the event that the parties fail to reach an agreement as to any
adjustment as contemplated by the second sentence of Section 2.2(c), BMS may or,
at TLC's request, shall engage its usual independent, certified public
accountant to examine such records of BMS as may be necessary to determine the
purchase price for the Product as provided in the first two sentences of Section
2.2(a).  The results of any such audit shall be promptly made available to TLC.
The party initiating the audit shall bear the full cost of the performance of
any such audit.  The determination by such independent, certified public
accountant pursuant to the foregoing as to the purchase price for the Product
shall be conclusive and binding upon both parties.

        2.3   Forecast: Ordering.
              ------------------ 

         (a)  The parties have heretofore agreed on a tentative supply schedule,
with respect to both timing and quantities, through December 31, 1994 for the
Product to be supplied by BMS hereunder.  Thereafter, with respect to each 12-
month period commencing each January, April, July or October, as the case may
be, TLC shall, not later than six months prior to the first day of such 12-month
period, provide BMS with a forecast of its quarterly requirement of the Product
for, together with a firm purchase order for the Product for the first quarter
of, such 12-month period, the first such 12-month period being that commencing
January 1, 1995 with respect to which TLC shall provide BMS with its forecast no
later than June 30, 1994. TLC

                                       6
<PAGE>
 
shall be required to specify in each such purchase order, thereby committing to
purchase from BMS, the amount specified in such purchase order, which amount
shall in any event be an amount not less than 90%, nor more than 110%, of the
amount projected for such first quarter as presented in the immediately
preceding 12-month forecast.

         (b)  Orders for the Product to be supplied by BMS hereunder may be on
TLC's standard purchase order form; provided, however, that, whether or not
                                    --------  -------                      
reference is made therein to this Agreement, the provisions of this Agreement
shall supersede the terms thereof and govern the terms of any sale of such
Products by BMS to TLC.  Each purchase order shall specify the date on which
delivery of the Product is required, which date shall be at least six months
following the date of the order and shall not be a date later than the
termination date as specified by BMS in its termination notice pursuant to
Section 8.9(b).  Each order shall be for a total quantity equal to an integral
multiple of the required batch quantity specified on Appendix B.  BMS shall
promptly acknowledge acceptance of such order in writing and advise TLC of the
anticipated shipment date of the Product ordered.  Once accepted by BMS, the
purchase order in question shall constitute a firm order on the part of TLC to
purchase from BMS the specified quantity of the Product and a firm commitment on
BMS's part to supply such specified quantity, subject, however, to BMS's
temporary or indefinite inability to supply the Product arising from delay or
interruptions in BMS's sourcing, or the unavailability, of crude amphotericin B
from third parties.

packaged and shipped in individual units of five base kilograms each and
otherwise in appropriate shipping containers, and under such conditions, as
agreed upon by the parties.

   2.5   Invoicing.  The invoice amounts shall be based on the purchase price as
         ---------                                                              
provided in Section 2.2(a), subject to any adjustment pursuant to Section
2.2(c).  Payments shall be made to BMS not later than 30 days following the date
of invoice or shipment, whichever is later.

   2.6   Restrictions on Product Use.  For purposes of limiting the scope of
         ---------------------------                                        
BMS's obligation hereunder to supply TLC with the Product and precluding any use
of the Product not contemplated by this Agreement, TLC agrees not to use the
Product acquired from BMS hereunder for any purpose other than for TLC's own
production of Complex (including production by TLC's contract manufacturers).

   2.7   Drug Master Files.  Upon TLC's reasonable request, BMS shall permit TLC
         -----------------                                                      
to cross-reference any pre-existing drug master file (or other comparable
regulatory documentation) maintained by BMS solely for the purpose of qualifying

assignable by either party without the prior written consent of the other party;

or to any successor by merger or sale of substantially all of its assets in a
manner such that the assignor shall remain jointly and severally liable and
responsible for the performance and observance of all its duties and obligations
hereunder. This Agreement shall be binding upon the successors and permitted
assigns of the parties. Any assignment not in accordance with this Section 7.1
shall be null and void.

   7.2   Force Majeure.  Neither party shall be liable to the other party for
         -------------                                                       
loss or damages, nor shall either party have any right to terminate this
Agreement, for any default or delay attributable to any act of God, flood, fire,

or accident, war, revolution, civil commotion, act of public enemies, blockage
or embargo, injunction, law, order, proclamation, regulation, ordinance, demand
or requirement of any government or subdivisions, authority or representative of
any such government, or any other cause beyond the reasonable control of the
defaulting party, if the party affected shall give prompt notice of any such
cause to the other party. The party giving such notice shall thereupon be
excused from such of its obligations hereunder as it is thereby disabled from
performing for so long as it is so disabled and for 30 days thereafter. Among
other contingencies subject to this Section 7.2, TLC expressly acknowledges that
BMS intends to continue to procure crude amphotericin B, a fermentation product,
from one or more third party suppliers and has no intention of producing such
material on its own. Notwithstanding the foregoing, nothing in

         (a)  Either party may, upon not less than 90 days' written notice to
the other party, terminate this Agreement; provided, however, that BMS shall

have no right to do so under this Section 7.9(a) unless there shall have

its Affiliates shall have ceased the commercial production of the Product.

         (c)  Failure by either party to comply with any of the material
obligations contained in this Agreement shall entitle the other party to give to
the party in default a written notice of default specifying the nature of the
default and requiring it to cure such default.  If such default is not cured
within 60 days after the receipt of such notice, the notifying party shall be
entitled, without prejudice to any of its rights conferred on it by this
Agreement, in addition to any other remedies available to it by law or in
equity, to terminate this Agreement by giving written notice to take effect
within 30 days after such notice.  The right of either party to terminate this

any reason shall have no effect on any purchase order already placed by TLC
hereunder, and shall otherwise be without prejudice to any rights which shall
have accrued to the benefit of either party, prior to such termination,
including, without limitation, each party's rights under Articles 4 and 5.

   7.10  Public Announcements.  Except as required by law or the regulations of

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

- ----------------------
     B-MS hereby grants to TLC an exclusive license to employ TECHNOLOGY for any
purpose in the FIELD and a non-exclusive license for any purpose outside the

Section 3.02 - Sublicense
- -------------------------
     TLC shall have the right to grant sublicenses to the extent of its licenses
under sections 3.01 to SUBLICENSEES and AFFILIATES without the consent of B-MS.
Any such SUBLICENSEES and AFFILIATES will be bound by the requirements of
confidentiality and use limitations to which TLC is obligated under this
AGREEMENT.

Section 3.03 - Royalties
- ------------------------
(a)  In consideration of the licenses granted to TLC by B-MS under Section 3.01
of this AGREEMENT, TLC agrees to pay B-MS a royalty equal to ____ percent of NET
SALES of COMPLEX, such royalty to be paid, subject to subsection (g) below, for
a period of ten (10) years on a country-by-country basis in each country in
which COMPLEX shall be sold by TLC, its AFFILIATES or SUBLICENSEES, the ten year
period commencing in a country with the FIRST COMMERCIAL SALE of COMPLEX by TLC,
its AFFILIATES OR SUBLICENSEES.

(b)  In further consideration of the licenses granted by B-MS to TLC under
Section 3.01, TLC agrees to pay B-MS an additional royalty equal to ____ percent
of NET SALES of COMPLEX on a country-by-country basis in each country in which
the COMPLEX shall be sold by TLC, its AFFILIATES or SUBLICENSEES, and in which a
LICENSED PATENT is in effect covering the manufacture, use or sale of COMPLEX,
for a period commencing with the FIRST COMMERCIAL SALE of 

                                      -5-
<PAGE>
 
COMPLEX by TLC, its AFFILIATES or SUBLICENSEES in the country and ending on the
day of expiration of the last-to-expire LICENSED PATENT in the country. However,
if in the sole opinion of TLC, it must pay a royalty to a third party so as not,
by its manufacture, use or sale of COMPLEX, to infringe a patent owned by the
third party, TLC may deduct this royalty payment to the third party from the
payment due B-MS under this subsection (b). The royalty payment due B-MS under
this subsection (b) will not be reduced to less than ____ percent of NET SALES
of COMPLEX. Payments due B-MS from TLC under subsections (b) and (c) of this
Section shall be cumulative and additive.

(c)  TLC shall owe only one royalty payment to B-MS under subsection (b) of this

the COMPLEX in that country.

(d)  TLC, its AFFILIATES and SUBLICENSEES shall keep true accounts of NET SALES
of COMPLEX and of all sums payable to B-MS under the terms of this AGREEMENT.
TLC shall deliver to B-MS written reports containing a statement of sales and
NET SALES during the preceding calendar quarter, and showing the calculation of
NET SALES. Such reports shall be sent by TLC to B-MS on or before the ninetieth
calendar day following the end of each calendar quarter during which this
AGREEMENT remains effective. At the same time, TLC shall pay B-MS the amount of
royalties due on NET SALES during the preceding calendar quarter.

(e)  The royalty payments due by TLC to B-MS shall be in U.S. dollars. In the
event that sales are made in a currency other than U.S. dollars, the sum of such
sales shall be converted to U.S. dollars according to the exchange rate for the
currency in which the sales were made, as listed in the Wall Street Journal for
the last business day of the quarter in which the sales were made.

(f)  Any income tax, or other tax, which TLC is required to pay or withhold with
respect to any payment due B-MS under the terms of this AGREEMENT shall be
deducted from the amounts due B-MS, provided that in regard to any such
deduction, TLC shall give B-MS reasonably necessary assistance in claiming

                                      -6-
<PAGE>
 
exemption therefrom, or full, or partial, refund thereof or tax credit therefor,
and shall promptly provide B-MS with proper evidence as to the payment of such
tax.

(g)  Notwithstanding subsections (a) and (b) above, on a country-by-country
basis, TLC shall have no obligation to pay B-MS any royalty hereunder in respect
of COMPLEX if, and for so long as, B-MS, or its AFFILIATES, pursuant to a
separate agreement with TLC, markets COMPLEX in the country in question.

                      ARTICLE IV - ACCESS AND CONSULTATION
                      ------------------------------------
                                        
Section 4.01
- ------------
     Upon the reasonable request of TLC, B-MS will make its employees who have
been involved with the FIELD or with the COMPLEX available during regular
business hours, and for a reasonable amount of time, for a period of two years
following execution of this AGREEMENT to meet with TLC personnel from time-to-
time, but only to the extent necessary to implement, pursuant to Section 2.01,
the transfer of TECHNOLOGY, with reimbursement by TLC for out-of-pocket expenses
incurred by B-MS.

                      FIRST AMENDMENT TO LEASE AGREEMENT
                      ----------------------------------


This First Lease Amendment (the "Amendment") is made this 29 day of October,
1993 between PEREGRINE INVESTMENT PARTNERS-I, a Pennsylvania limited partnership
("Landlord") and THE LIPOSOME COMPANY, INC., a Delaware corporation ("Tenant").

     Landlord and Tenant entered into a Lease dated December 14, 1992 (the
"Lease") pursuant to which Landlord agreed to lease and Tenant agreed to rent
certain space situated in Arbor 600, 600 College Road East, Princeton Forrestal
Center, Plainsboro, New Jersey, as more particularly defined in the Lease (the
"Premises"). Landlord and Tenant have agreed to amend the Lease in accordance
with the terms set forth at length below.

     NOW, THEREFORE, intending to be legally bound hereby, the Landlord and
Tenant agree as follows:

     1. Except as otherwise expressly provided herein, the terms defined in the
Lease shall have the same meaning in this Amendment as in the Lease.

     2. Landlord will make available for occupancy by Tenant, as soon as
possible following submission of construction drawings by Tenant, but no more
than 60 days after submission of construction drawings, that portion of the
fourth floor of the Building shown on Exhibit A as the "Additional Premises".
Tenant may occupy the Additional Premises as soon as a Temporary Certificate of
Occupancy is received for the Additional Premises.

     3. Effective upon the sooner of the date of occupancy of the Additional
Premises or April 1, 1994, the Premises shall be changed to include the
Additional Premises, the Rentable Area shall be increased by 7,568 square feet
and Tenant's Allocated Share shall be 12.01%.

     4. Effective April 1, 1994, Basic Rent on the Premises shall be increased

period, payable in accordance with the Lease.

April 1, 1998 to Lease Expiration: $14,505.33 per month for each month in the
period, payable in accordance with the Lease.

     Nothing herein is meant to change Tenant's right to terminate this Lease at
the end of the fifth year of the initial lease term in accordance with the
notice provisions in paragraph 2 of the Lease. For purposes of establishing the
Lease Expiration Date, and the date on which the Lease may be terminated, the
actual Lease Commencement Date is established as April 1, 1993.

paid in accordance with the provisions of the Lease as amended hereby.

     6. The Additional Premises shall be finished, at Landlord's expense, in
accordance with the plan submitted by Tenant and attached hereto as Exhibit A,
complete with the same finishes and electric as Tenant currently has in its
existing Premises. Tenant to pay for any unusual requirements such as floor
reinforcing, and any changes made after final construction documents are
submitted to Landlord.

     7. Effective upon execution of this Amendment paragraph 24(s) of the Lease
is amended by substituting "approximately 7,500 contiguous rentable square feet
anywhere in the Building", in place of the "Expansion Space" now set forth in
Exhibit A-1 to the Lease and substituting "between October 15, 1994 and October
15, 1996" in place of "not earlier than one (1) year following the Commencement
Date nor later than three (3) years following the Commencement Date". Landlord's
obligation shall be unchanged with respect to the same.


     8. Except as expressly amended herein, the terms and conditions of the
Lease shall remain in full force and effect and Tenant and Landlord expressly
ratify and confirm those terms and provisions.

     IN WITNESS WHEREOF, the parties have set their hands as of the date first
above referenced.

to in this Lease except as may herein be expressly otherwise provided.

5.6  -  If any governmental license or permit shall be required for the proper

this amount shall not be deemed to cure the occurrence of an Event of Default or

Taxes and/or insurance by the date on which such payments are due. If unknown,
Landlord shall reasonably estimate the amount of Real Property Taxes and/or
insurance premiums when due, based upon the immediately prior bills and the
advice of the tax collecting authority or the insurance company representatives
for such estimated payment. Tenant shall pay any deficiency of funds in the

Lease, Landlord may apply any funds in the impound account to any obligation
then due under this Lease. In the event the estimated payments exceed the actual

Tenant any such excess. Landlord shall, upon the request of Tenant, provide
Tenant with copies of tax and/or insurance bills and evidence of payment of
same.

injury, loss, claims, or damages to any person or property occasioned by or in
connection with any Tenant Changes.

9.4 - Any such Tenant Changes shall be performed in such manner as not to delay

          the Premises.   Tenant acknowledges that Landlord shall not obtain
          insurance for Tenant's fixtures or equipment or building improvements
          installed by Tenant on the Premises.  Tenant shall be liable for the
          payment of any deductible amount under Landlord's or Tenant's
          insurance policies maintained pursuant to this Section, in an amount
          not be exceed Five Thousand Dollars ($5,000.00).  Tenant shall not do
          or permit anything to be done which invalidates any such insurance
          policies.

10.2 - All of the aforesaid insurance shall be written by one or more
responsible insurance companies satisfactory to Landlord and in form
satisfactory to Landlord and with carriers having at least a Best's A+ rating.
The Comprehensive Public Liability insurance shall contain endorsements
substantially as follows:

               "It is understood and agreed that the insurer will give to One
               Research Way Partners (or any successor Landlord) c/o Keller,
               Dodds & Woodworth, Inc., 103 Carnegie Center, Princeton, New
               Jersey 08543, ten (10) days prior written notice of cancellation
               of this policy."

10.3 - Tenant shall be solely responsible for payment of premium and Landlord
(or its designee) shall not be required to pay any premium for such insurance.
Tenant shall use best efforts to deliver to Landlord at least fifteen (15) days
prior to the time such insurance is first required to be carried by Tenant, and
thereafter at least fifteen (15) days prior to the expiration of such policy,
either a duplicate original or a certificate it being the intention of the
parties hereto that the insurance required under the terms hereof shall be
continuous during the entire term of this lease and in form acceptable to
Landlord and any other period of time during which, pursuant to the term hereof,
said insurance is required. Tenant shall promptly notify Landlord of any
material change in its liability policy, which change materially alters the
coverages afforded Landlord herein.

                                      -11-
<PAGE>
 
10.4 - Tenant agrees, at its own cost and expense, to comply with all of the
rules and regulations of the Fire Insurance Rating organization having
jurisdiction and any similar body. If, at any time or from time to time, as a
result of or in connection with any failure by Tenant to comply with the
foregoing sentence or any act of omission or commission by Tenant,  its
employees,  agents, contractors or licensees, or as a result of or in connection
with the use to which the premises are put (notwithstanding that such use may be
for the purposes hereinbefore permitted or that such use may have been consented
to by Landlord), the fire insurance rate(s) applicable to the Premises or the
Building in which same are located shall be higher than that which would be
applicable for the least hazardous type of occupancy legally permitted therein,
Tenant agrees that it will pay to Landlord as Additional Rent, such portion of
the premiums for all fire insurance policies in force with respect to the
aforesaid properties and the contents of any occupant thereof as shall be
attributable to such higher rate(s).

10.5 - Landlord makes no representation that the limits of liability specified
to be carried by Tenant or Landlord under the terms of this lease are adequate
to protect Tenant against Tenant's undertaking under this Article 10, and in the
event Tenant believes that any such insurance coverage called for under this
Lease is insufficient,  Tenant shall provide,  at its own expense,  such
additional insurance as Tenant deems adequate.

10.6 - The liability insurance obtained by Tenant under this Paragraph shall (i)
be primary and non-contributing and (ii) contain cross-liability endorsements.
The amount and coverage of such insurance shall not limit Tenant's liability nor
relieve Tenant of any other obligation under this Lease.  Landlord may also
obtain comprehensive public liability insurance, provided that such insurance
obtained by Landlord shall not be contributory and shall not provide primary
insurance.

ARTICLE 11 - INDEMNIFICATION
             ---------------

11.1 - Tenant and Landlord shall each save and hold one another harmless from
and against all liability, claims, and demands on account of personal injuries
or property loss or damage of any kind whatsoever which arise out of or are in
any manner connected with, or are claimed to arise out of or are in any manner
connected with, and which result from, and only from, the negligent act of such
other party.

ARTICLE 12 - FIRE
             ----

12.1 - In the event of the total destruction of the Building or the Premises by
fire or other casualty during the term hereof or in the event of such partial
destruction thereof as to render the Premises wholly untenantable or unfit for
occupancy, then in either event, unless such damage can, in the reasonable
opinion of Landlord, be repaired within one (1) year after the occurrence, this
Lease and the term hereby created shall at either party's option, to be
exercised within fifteen (15) days after notice from Landlord as hereinafter
provided, cease from the date of such damage or destruction, and Tenant shall
upon written notice from Landlord immediately surrender the Premises to Landlord
and Tenant shall pay rent within said term only to the time of such damage or
destruction. If, however, in Landlord's 

                                      -12-
<PAGE>
 
reasonable opinion, the damage as aforesaid can be repaired within one (1) year
from the occurrence thereof, Landlord shall (unless Landlord shall elect not to
repair or rebuild, as hereinafter provided) repair the Premises with all
reasonable speed, this Lease shall continue in full force and effect and there
shall be an abatement of rent (to the extent of Landlord's receipt of rental
insurance proceeds in an amount equal to the Minimum Rent and Additional Rent)
until the repair is completed so that Tenant can occupy the Premises. Landlord
shall notify Tenant within thirty (30) days from the occurrence of the
destruction as to whether or not the damage can be repaired within one (1) year
after the occurrence thereof.

12.2 - In the event of the partial destruction of the Building or Premises by
fire or other casualty during the term hereof, which  partial destruction does
not render the Premises wholly untenantable or unfit for occupancy, for more
than one (1) year in the Landlord's reasonable opinion, Landlord shall (unless
Landlord shall elect not to repair or rebuild as hereinafter provided) repair
the damage with all reasonable speed, this Lease shall continue in full force
and effect and there shall be an abatement of rent (to the extent of Landlord's
receipt of rental insurance proceeds in an amount equal to the Minimum Rent and
Additional Rent) until the repair work is completed so that Tenant can occupy
the Premises, in such proportion as the part of the Premises destroyed or
rendered untenantable bears to the total leased Premises. If such damage cannot
be repaired within one (1) year after the occurrence in the reasonable opinion
of Landlord, this Lease and the term hereby created, at either party's option
(to be exercised within fifteen (15) days after notice from Landlord as
hereinafter provided) shall cease from the date of such damage or destruction as
provided in Section 12.1. Landlord shall notify Tenant within thirty (30) days
from the occurrence of the destruction as to whether or not the damage can be
repaired within one (1) year after the occurrence thereof.

12.3 - In the event that the Premises shall be so slightly damaged by fire or
other casualty so as not to affect or only slightly affect the operation of
Tenant's business in the Premises, then in that event, there shall be no
abatement of rent and this Lease shall continue in full force and effect, and
Landlord shall enter and repair the damage with all reasonable speed.

12.4 - In the event that the Landlord elects, after any such total, partial or
minimal damage or destruction, to reconstruct the Premises pursuant to this
Lease, Landlord shall not have any liability whatsoever to Tenant to refit the
Premises beyond the Building Standard, together with those alterations and
improvements as set forth in Exhibit "D" attached hereto(such augmented fitting
up hereafter referred to as the "Standard Tenant Fit-Up Specifications"). Tenant
shall have the option as to whether and how to refit the Premises and, within
the notice periods set forth above, shall be entitled to instruct Landlord to
repair or replace any or all of the Building or Premises only up to Standard
Tenant Fit-up Specifications.  However, Tenant's election shall have no effect
whatever on Tenant's continuing obligation to pay Minimum Rent and Additional
Rent hereunder. If Tenant shall elect to refit the Premises beyond Standard
Tenant Fit-up Specifications, such refitting shall be done at Tenant's sole cost
and expense. If Tenant shall elect not to have Landlord repair or replace beyond
Standard Tenant Fit-up Specifications, Tenant shall be entitled to all insurance
proceeds in excess of those required by Landlord in the repair or replacement to
the level of Standard Tenant Fit-up 

                                      -13-
<PAGE>
 
Specifications, and shall also be entitled to the return of the Letter of Credit
referred to in Article 37 hereinafter.

12.5 - Notwithstanding anything contained herein to the contrary:

          (a)  if during the last two (2) years of the term of this Lease (which
          shall be deemed to include any extension periods granted Tenant
          herein) the Premises or the Building shall be so damaged by fire or
          other casualty that the Landlord decides not to repair or rebuild, or

          (b)  if the same are damaged by a casualty which is not insurable
          under standard or extended coverage insurance, or if the proceeds of
          such insurance are not made available to Landlord, or if such
          proceeds, together with such payment which Tenant is willing to make
          toward such repair or replacement are, in Landlord's reasonable
          judgment, insufficient to repair or rebuild, and Landlord decides in
          its reasonable judgment either (i) not to repair or rebuild, or (ii)
          to demolish the entire Building and rebuild same,

then upon the happening of any such event Landlord may cancel this Lease by
giving written notice of such cancellation to Tenant within thirty (30) days
after the happening of such damage and thereupon this Lease and the term hereof
shall cease and terminate as of the date of the happening of such damage, and
rent and other charges payable by Tenant shall be pro-rated to the day of such
damage.

12.6 - Landlord shall use its best efforts to effect any such repair  or
restoration  promptly  and  in  such  manner  as  not unreasonably to interfere
with Tenant's use and occupancy of the Premises but such efforts shall be
subject to (i) Landlord's inability to obtain materials, (ii) Acts of God, (iii)
strikes, fire or weather, (iv) acts of governmental authority, or (v) any other
cause beyond the control of Landlord. Notwithstanding the above, Landlord shall
not be required to incur overtime or additional charges in any such repair or
restoration of the Premises or of the Building pursuant to this Article 12.

12.7 - The provisions of this Article 12 shall be considered an express
agreement governing any case of damage or destruction of the Premises by fire or
other casualty, and any law of the State of New Jersey providing for such a
contingency in the absence of an express agreement,  and any other law of like
import,  now or hereafter in force, shall have no application in such case.

12.8 - In case of any damage by fire or other casualty, Tenant shall immediately
notify Landlord.

                                      -14-
<PAGE>
 
ARTICLE 13 - EMINENT DOMAIN
             --------------

13.1 - In the event that the entire or substantially the entire Premises or
Building should be taken for any public or quasipublic use or should be taken by
right of eminent domain or any other right, or should be sold to the condemning
authority in lieu of condemnation, then this Lease shall terminate as of the
date when physical possession of the Building or the Premises is taken by the
condemning authority.

13.2 - The Landlord or the Tenant may exercise the aforesaid right or rights to
terminate this Lease in its entirety as aforesaid by giving written notice to
the other within sixty (60) days after the date of the vesting of title in such
proceeding, specifying a date not more than thirty (30) days after the giving of
such notice as the date for such termination.

13.3 - In the event of any taking of the Building or the Parcel, Landlord shall
be entitled to receive so much of such award as is applicable to Landlord's
leasehold interest and to the Standard Tenant Fit-Up Specifications and Tenant
hereby assigns to Landlord any and all right, title and interest of Tenant in or
to such portion of any such award or any part thereof and hereby waives all
rights against Landlord and the condemning authority. Tenant shall have the
right to claim and prove in any such proceeding and to receive any award which
may be made, if any, specifically for the value of the Building above and beyond
the value of the Standard Tenant Fit-Up Specifications, Tenant's moving expenses
and damages or condemnation of Tenant's movable trade fixtures and equipment.

13.4 - In the event that this lease is not terminated after the eminent domain
proceeding, Landlord shall promptly commence to repair or restore the Premises,
at Landlord's expense (providing that Landlord shall have received adequate
compensation for the taking), to Standard Tenant Fit-Up Specifications and
complete same with due diligence, except for delays caused by (i) Landlord's
inability to obtain materials, (ii) Acts of God, (iii) strikes, fire or weather,
(iv) acts of governmental authority, or (v) any other cause beyond the control
of Landlord, and the Minimum and Additional Rent shall be equitably reduced from
and after the date title vests in the condemnor for the balance of the term by
taking into account the character and the amount of the taking. The foregoing
repair and restoration by Landlord shall exclude repair and/or restoration of
Tenant's fixtures or decorations, for which Tenant shall be solely responsible.
If Tenant elects to repair or replace its fixtures and to restore the Laboratory
Area or the Manufacturing Area to its condition as such, Landlord shall not be
responsible to perform work so as to restore to the Standard Tenant Fit-up
Specifications, but shall be obligated only to make available to Tenant funds
equal to what would have been Landlord's cost to restore such portion of the
Building to the Standard Tenant Fit-up Specifications standard. The Tenant's
Percentage shall be adjusted to reflect the balance of square feet of rentable
area remaining as the Premises subsequent to said eminent domain proceeding.

                                      -15-

ARTICLE 14 - ASSIGNMENT  OR SUBLETTING
             ----------- -- ----------

14.1 - Tenant agrees not to sell, assign, mortgage, hypothecate, pledge, or in
any manner transfer this Lease or any estate or interest hereunder and not to
sublet the Premises or any part or parts thereof without the previous written
consent of Landlord, which consent by Landlord shall not be unreasonably
withheld,  conditioned or  delayed. If Tenant violates the provisions of this
Article 14, Landlord may accept from any assignee, sublessee, licensee,
concessionaire or anyone who claims a right to the interest of Tenant under this
lease or who occupies any part or the whole of the Premises the payment of
Minimum Rent and Additional Rent and/or the performance of any of the other
obligations of Tenant under this lease, but acceptance shall not be deemed to be
a waiver by Landlord of the breach by Tenant of the provisions of this Article
14, nor a recognition  by  Landlord  that  any  such  assignee, sublessee,
licensee, concessionaire, claimant or occupant has succeeded to the rights of
Tenant hereunder, nor a release by Landlord of Tenant from further performance
by Tenant of the covenants on Tenant's part to be performed under this lease;
provided, however, that the net amount of rent collected from any such assignee,
sublessee, licensee, concessionaire, claimant or occupant shall be applied by
Landlord to the rent to be paid hereunder. Any consent by Landlord to any such
assignment, transfer, subletting, license or concession or other matter or thing
contained in this Article 14 shall not in anywise be construed to relieve Tenant
from obtaining the prior consent of Landlord to any other or further such
assignment, transfer, subletting, license, concession, matter or thing.

14.2 - If Tenant shall desire to assign this Lease or to sublet all or a portion
of the Premises, Tenant shall submit to Landlord a written request for
Landlord's consent to such assignment or subletting, which request shall contain
or be accompanied by the following information:  (i) the name and address of the
proposed assignee or subtenant; (ii) in the case of a proposed subletting, a
description identifying the space to be sublet (the "Sublet Space"); (iii) the
nature and character of the business of the proposed assignee or subtenant and
of its proposed use of the Premises; and (iv) the effective date of such
proposed assignment or subletting (the "Termination Date"). If the Landlord
consents to any assignment or sublet as provided in Section 14.1, the Minimum
Rent applicable to the Premises or sublet portion thereof shall be  adjusted as
follows:

     (a)  Commencing on the effective date of the assignment or sublet (the
"Assignment/Sublet Date"), the Minimum Rent as provided in Article 4 (for both
the initial Minimum Rent of $11.50 per square foot and the Minimum Rent
commencing on  the seventy (7th) anniversary of the Commencement Date at the
rate of $14.00 per square foot) shall be increased by the percentage increase
between the Consumer Price Index (as defined in Article 35) for the month in
which this Lease is dated, and the Consumer Price Index for the month in which
the assignment or subletting occurs.  The Minimum Rent, as increased pursuant to
this Subsection 14.2(a) shall be referred to as the "Revised Rent."

     (b)  Commencing on the first anniversary of the Assignment/Sublet Date, the
Revised Rent shall be adjusted as follows:

                                      -16-
<PAGE>
 
               (i)  The term "Index Month" shall mean the calendar month in
          which the Assignment/Sublet Date occurs, and thereafter, the calendar
          month in which each anniversary of the Assignment/Sublet Date occurs.

               (ii)  The "Percentage Increase" shall mean the annual percentage
          increase, if any, in the Consumer Price Index yielded by dividing the
          difference between the Consumer Price Index for one Index Month and
          the Consumer Price Index for the immediately preceding Index Month, by
          the Consumer Price Index for the earlier of the two Index Months
          compared.

               (iii) The Landlord shall ascertain the Consumer Price Index for
          first Index Month and for each succeeding Index Month, and shall also
          determine the Percentage Increase.

          (iv) Effective on the first anniversary of the Assignment/Sublet Date
          and thereafter on each anniversary of the Assignment/Sublet Date, the
          Revised Rent shall be increased by multiplying (a) the amount of the
          Revised Rent, with respect to the first anniversary of the
          Assignment/Sublet Date, or (b) the amount of the Revised Rent as the
          same may have been increased by previous application of the Consumer
          Price Index adjustment provisions hereof, with respect to the
          subsequent anniversaries of the Assignment/Sublet Date, by the
          Percentage Increase plus 100%, which amount so obtained shall become
          the Revised Rent for the subject year.

               (v)  The Landlord shall send a statement to the Tenant within one
          hundred twenty (120) days after each anniversary of the
          Assignment/Sublet Date, setting forth the adjustment made in the
          Revised Rent, which shall be for informational purposes and not a
          condition to the effectiveness of such adjustment. Prior to receipt of
          such statement of adjustment, Tenant shall continue to pay the Minimum
          Rent or the Revised Rent as then in effect. Within twenty (20) days
          following receipt of such statement Tenant shall pay Landlord any
          deficiency in the Revised Rent resulting from the annual adjustment.

               (v)   In no event shall any adjustment based upon the Consumer
          Price Index result in a reduction of the Minimum Rent.

               (vi) All annual increases as provided in this Subsection 14.2(b)
          shall apply to both the initial Minimum Rent of $11.50 per square foot
          and the Minimum Rent commencing on the seventh (7th) anniversary of
          the Commencement Date at the rate of $14.00.

Landlord shall be entitled to receive the Revised Rent and Tenant shall be
entitled to receive from such assignees or subtenants any amount above the
Revised Rent which Tenant can obtain, and Landlord shall have no claim to any
such excess amount.

                                      -17-
<PAGE>
 
14.3 - Notwithstanding the foregoing provisions of this Article 14, Tenant shall
have the right, without Landlord's consent, to assign this lease or to sublet
all or any portion of the premises to an "Affiliate", but no such assignment or
subletting shall relieve Tenant  of  its  obligations  to  Landlord  hereunder.
The  term "Affiliate"  shall  mean  any  business entity that controls, is
controlled by or is under common control with Tenant or any such entity which
results from the merger or consolidation with Tenant or to any such entity which
acquires all of Tenant's assets as a going concern so long as such entity
assumes the obligations of Tenant under this Lease.

 
It is understood that neither Section 14.1 or Section 14.2 shall apply to any
assignment or subletting to an Affiliate, except that such Affiliate shall be
deemed bound by all of the other terms and conditions of this Lease, and any
Affiliate who is an assignee of this Lease shall agree with Landlord in writing
to assume all of the obligations of this Lease and to attorn to Landlord. No
Affiliate  which is  an  assignee  or  subtenant  hereunder  shall thereafter be
permitted to assign the Lease or further sublet the Premises or portion thereof
under its control, except to an entity which is itself an Affiliate of such
Affiliate, without  first complying with the provisions of Sections 14.1 and
14.2.

Tenant shall notify Landlord of any assignment or subletting to an Affiliate at
least thirty (30) days prior to the date of such subletting or assignment. Such
notification shall be accompanied by evidence reasonably satisfactory to
Landlord which demonstrates such proposed assignee's or subtenant's status as an
Affiliate.

ARTICLE 15 - ENTRY BY LANDLORD
             -----------------

15.1 - Landlord, by its duly authorized employees and agents, may, except as
limited herein, enter the Premises at reasonable hours, (i) to inspect the same,
(ii) to make repairs required of Landlord hereunder, or to make repairs,
alterations or improvements to any portion of the Building, and (iii) to perform
any work therein that may be necessary to comply with any laws, statutes,
ordinances, regulations, orders and requirements of all governmental authorities
having jurisdiction over the Premises, or to prevent waste or deterioration of
the Premises; provided, however, that all such work shall be done as promptly as
reasonably possible and so as to cause  as  little  interference to Tenant as
reasonably possible.  Before performing any work in or affecting Tenant's
Laboratory Area or Manufacturing Area, Landlord must notify Tenant. Any repairs,
alterations or improvements to the Premises shall be done after normal business
hours except for emergency repairs which shall be done as required. Landlord
may, during the progress of any such work keep and store upon the Premises, all
necessary materials, tools and equipment required for said work but Tenant shall
not be responsible therefor. Landlord shall at all times retain a key with which
to unlock all of the doors in, on or about the Premises (excluding Tenant's
vaults, safes, sterile and similar areas which are hereby designated by Tenant);
and Landlord shall have the right to use any and all means which Landlord may
deem proper to open said doors, except the doors to such laboratory and
manufacturing areas until emergency notice has been given to Tenant, in an
emergency in order to obtain entry to the Premises, and any entry to the
Premises obtained by Landlord by 

                                      -18-
<PAGE>
 
any of said means or otherwise shall not under any circumstances be construed or
deemed to be forcible or unlawful entry into or a detainer of the Premises or an
eviction, actual or constructive, of Tenant from the Premises or any portion
thereof.

ARTICLE 16 - INSPECTIONS BY PROSPECTIVE PURCHASERS AND TENANTS AND BY LENDERS
             ----------------------------------------------------------------

16.1 - The Landlord is hereby given the right upon the giving of forty-eight
(48)  hours' prior notice to Tenant (which period shall include at least two (2)
business days), to enter the Premises during usual business hours (i) to exhibit
the same to prospective Building purchasers or prospective or current lenders at
any time during the lease term or any renewal thereof, and (ii) to exhibit the
same to prospective tenants within twelve (12) months prior to the expiration of
the lease term or any renewal thereof. A representative of Landlord shall always
accompany any such  purchaser,  tenant  or  lender  on  any  of  the  aforesaid
inspections. A representative of Tenant shall be present whenever any portion of
the Premises are entered by  Landlord  and/or any  third  parties,  such  as
prospective tenants, lenders or purchasers, for purposes set forth under this
Section 16.1. Tenant shall have the right to impose reasonable restrictions
(such as gowning) upon the right of such parties to enter the Laboratory Area
and Manufacturing Area.

ARTICLE 17 - SURRENDER
             ---------

17.1 - On the last day of the term demised,  or the sooner termination thereof,
Tenant shall peaceably surrender the Premises broom clean, in good order,
condition and repair wear and tear excepted. On or before the last day of the
term or the sooner termination thereof, Tenant shall, at its expense, remove its
trade fixtures and signs from the Premises, and, subject to the limitations set
forth in  Section 17.2, shall restore the Laboratory Area and Manufacturing Area
to the Building Standard, as set forth in Schedule C. Any property not removed
shall be deemed abandoned and may be removed and disposed of by Landlord and the
expense of such removal shall be paid to Landlord by Tenant without any setoff
for the salvage value of goods so removed.  If the Premises be not surrendered
at the end of the term or the sooner termination thereof, Tenant shall indemnify
Landlord against loss or liability resulting from delay by Tenant in so
surrendering the Premises, including, without limitation, claims made by any
succeeding tenant founded on such delay. Tenant shall promptly surrender all
keys for the Premises to Landlord at the place then fixed for payment of rent.
Tenant's covenants hereunder shall survive the expiration or termination of this
Lease.

17.2 - Landlord agrees that in the marketing of the Premises to prospective
tenants for use after the term of this Lease, it will use commercially
reasonable efforts to lease the Premises as improved with all alterations and
improvements made by Tenant, including the Tenant Changes and all work done
before the term of this Lease (collectively, the "Alterations").  Whether such
proposed tenant was found through Tenant's or Landlord's efforts, Landlord
agrees to negotiate with such proposed tenant in good faith, including
negotiations regarding the use by such tenant of some or all of the Alterations.
In the event that such tenant enters into a lease which calls for some or all of
the Alterations to remain, Landlord shall relieve 

                                      -19-
<PAGE>
 
Tenant of its obligation to restore any such portion of the Premises to the
Building Standard set forth in Schedule C. This Section 17.2 is intended to
provide the ability for Tenant to relieve itself of its financial responsibility
to restore the Laboratory Area and the Manufacturing Area. This Section is not
intended to impose any greater burden upon Tenant than that of removing the
Alterations and restoring the Premises to the standard set forth in Section 9.5
hereinbefore. Therefore, Tenant shall not be obligated, in the aggregate, to do
any more work or incur any greater expense than it would have incurred in
restoring the Premises to Building Standard. Landlord shall remain obligated to
perform all tenant fitup for any such new tenant, including the moving or
modification of any Alterations. By way of example, if the new tenant indicates
that it intends to rent from Landlord ten thousand (10,000) square feet of
existing Laboratory Area, Tenant shall not be responsible to make any
renovations to that space and would restrict its restoration work to the other
portions of the Premises.

17.3 - If the Tenant shall occupy the Premises with the consent of the Landlord
after the expiration of this Lease and rent is accepted from said Tenant, such
occupancy and payment shall be construed as an extension of this Lease for a
term expiring on the last day of the month next following the month in which the
said Lease expired, and occupation thereafter shall operate to extend the term
of this Lease for one (l) month at a time unless other terms of such extension
are made in writing and signed by the parties hereto. In such event, if either
Landlord or Tenant desires to terminate said occupancy at the end of any month
after the termination of this Lease, the party so desiring to terminate the same
shall give the other party at least thirty (30) days written notice to that
effect. Failure on the part of the Tenant to give such notice shall obligate it
to pay rent for an additional calendar month following the month in which the
Tenant has vacated the Premises.

ARTICLE 18 - DEFAULT
             -------

18.1 - Tenant shall, without any previous demand therefor, pay to Landlord the
Minimum Rent and Additional Rent at the times and in the manner heretofore
provided.

          In the event:

          (a)  of default in the payment of said rents or of any installment or
          part thereof, or in the payment of any other sum or any part thereof
          which may become due from Tenant to Landlord hereunder, at the time
          and in the manner provided herein, and if the same shall remain in
          default for ten (10) days after becoming due, or

          (b)  of the violation by Tenant of any of the covenants, agreements
          and conditions herein provided or of any of the Rules and Regulations
          now or hereafter reasonably established by Landlord, and the failure
          to cure such violation within thirty (30) days after notice in writing
          of such violation by Landlord to Tenant;

then upon the happening of any such event, Landlord may, at its option, elect
either to terminate this Lease or to enter the said Premises as the agent of
Tenant, without being liable 

                                      -20-
<PAGE>
 
for any prosecution or damage therefor, and relet the Premises as the agent of
Tenant, and receive the rent therefor, upon such terms as shall be satisfactory
to Landlord, and all rights of Tenant to repossess the Premises under this Lease
shall cease and end upon such termination or entry. Such entry for reletting by
Landlord shall not operate to release Tenant from any rent to be paid or
covenants to be performed hereunder during the full term of this Lease. For the
purpose of reletting, Landlord shall be authorized to make such repairs or
alterations in or to the Premises as may be necessary to place the same in good
order and condition. Tenant shall be liable for and hereby agrees to pay to
Landlord the cost of such repairs or alterations and all expenses of such
reletting. If the sum realized or to be realized from the reletting is
insufficient to satisfy the rent provided in this Lease, Landlord, at its
option, may require Tenant to pay such deficiency month by month (or at any
greater intervals), or may hold Tenant in advance for the entire deficiency
resulting from such reletting. Landlord shall look first to Tenant's Letter of
Credit, as described in Article 37. Only after that Letter of Credit is fully
used shall Landlord be granted a lien, in addition to any statutory lien or
right to distrain that may exist, on all personal property of Tenant in or upon
the Premises, including, without limitation, furniture, fixtures (including
trade fixtures) and merchandise of Tenant, to assure payment of the rent and
performance of the covenants and conditions of this Lease. Landlord shall have
the right, as agent of Tenant, to take Possession of all personal property of
Tenant found in or about the Premises, including, without limitation, furniture
and fixtures of Tenant, and sell the same at public or private sale and to apply
the proceeds thereof to the payment of any monies becoming due under this Lease,
or remove all such effects and store the same in a public warehouse or elsewhere
at the cost of and for the account of Tenant, or any other occupant.

18.2 - In the event of any breach by Tenant of any of the agreements, terms,
covenants or conditions contained in this lease, Landlord shall be entitled to
enjoin such breach and shall have the right to invoke any right and remedy
allowed at law or in equity or by statute or otherwise as though re-entry,
summary proceedings, and other remedies were not provided for in this Lease.

18.3 - Each right and remedy of Landlord provided for in this Lease shall be
cumulative and shall be in addition to every other right or remedy provided for
in this Lease or now or hereafter existing it law or in equity or by statute or
otherwise, and the exercise or beginning of the exercise by Landlord of any one
or more of the rights or remedies provided for in this Lease or now or hereafter
existing at law or in equity or by statute or otherwise shall not preclude the
simultaneous or later exercise by Landlord of any or all other rights or
remedies provided for in this lease or now or hereafter existing at law or in
equity or by statute or otherwise.

18.4 - If the term of this Lease shall be terminated due to default by the
Tenant of any of the terms or covenants herein contained, this Lease and the
term and estate hereby granted, whether or not the term shall heretofore have
commenced, shall terminate with the same effect as if that day were the
expiration date of the term of this lease, but Tenant shall remain liable for
all damages as are provided for herein.

ARTICLE 19 - BANKRUPTCY
             ----------

                                      -21-
<PAGE>
 
19.1 - At any time prior to or during the term of this Lease, if Tenant shall
make an assignment for the benefit of its creditors; or if Tenant shall file a
voluntary petition in bankruptcy; or if Tenant shall be adjudicated a bankrupt
or insolvent; or if the affairs of Tenant shall be taken over by or pursuant to
an order of any court or of any other officer or governmental authority pursuant
to any federal, state or other statute or law; or if Tenant shall admit in
writing its inability to pay or does not pay debts generally as they become due;
or if Tenant shall file any Petition  or  answer  seeking  any  reorganization,
arrangement, composition,  readjustment,  liquidation,  dissolution or similar
relief under the present or any future federal bankruptcy act or any other
present or future applicable federal, state or other statute or law; or if
Tenant shall seek or consent to or acquiesce in the appointment of any trustee,
receiver or liquidator of Tenant or of all or any substantial part of its
property; or, if, within sixty (60) days after the commencement of any
proceedings against Tenant  seeking  any  reorganization,  arrangement,
composition, readjustment, liquidation, dissolution or similar relief under the
present or future federal bankruptcy act or any other present or future
applicable federal, state or other statute or law, such proceedings shall have
not been dismissed; or, if, within sixty (60)  days  after  the  appointment,
without  the  consent  or acquiescence of Tenant, of any trustee, receiver or
liquidator of Tenant or of all or any substantial part of its property, such
appointment shall not have been vacated or stayed or dismissed; or if, within
sixty (60) days after the expiration of any such stay, such appointment shall
not have been vacated; or in the event action shall be taken by Tenant in
furtherance of any of the aforesaid purposes, then and in any such event, this
Lease and all rights of Tenant herein shall be automatically terminated, and in
such event neither Tenant nor any person claiming by, through or under Tenant by
virtue of any statute or of an order of any court shall be entitled to
possession or to remain in possession of the Premises but shall forthwith quit
and surrender the Premises. Such causes for the termination of this lease as set
forth in this Article 19 shall constitute a default by Tenant and all rights and
remedies stated or otherwise reserved under Article 18 hereof shall be available
to Landlord. The word "Tenant" in this Article 19 shall be construed to include
any Surety or Guarantor of this lease.

19.2 - It is stipulated and agreed that in the event of the termination of this
Lease pursuant to this Article 19, Landlord shall forthwith, notwithstanding any
other provisions of this Lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference between
the rent reserved hereunder for the unexpired portion of the term demised and
the then fair and reasonable rental value of the Premises for the same period.
In the computation of such damages the difference between any  installment of
rent becoming due hereunder after the date of termination and the fair and
reasonable rental value of the Premises  for the period for which such
installment was payable  shall  be discounted to the  date of termination at the
rate of four (4%) per cent per annum. If such Premises or any part thereof be
relet by the Landlord for the unexpired term  of  said  lease,  or  any part
thereof,  before presentation of proof of such liquidated damages to any court,
commission or tribunal,  the amount of rent reserved upon such reletting shall
be prima facia evidence as to the fair and reasonable rental value for the part
or the whole of the Premises so relet during the term of the reletting. Nothing
herein contained shall limit or prejudice the right of the Landlord to prove and
obtain as liquidated damages by reason of such termination an amount 

                                      -22-
<PAGE>
 
equal to the maximum allowed by any statute or rule of law in effect at the time
when, and governing the proceedings in which such damages are to be proved,
whether or not such amount be greater than, equal to or less than the amount of
the difference referred to above.

ARTICLE 20 - QUIET ENJOYMENT
             ---------------

20.1 - Tenant, subject to the terms and provisions of this Lease and to all
mortgages and underlying leases of record to which this Lease may be or may
become subordinate, on payment of all Minimum Rent and Additional Rent and
observing, keeping and performing all of the terms  and provisions  of this
Lease,  shall  lawfully, peaceably and quietly have, hold, occupy and enjoy the
Premises during the term hereof.  This covenant shall be binding on Landlord
only during its ownership of the Premises.  In the event Landlord shall sell or
otherwise dispose of its interest in the Premises during the term of this Lease,
such sale or other disposition shall operate to release and relieve Landlord,
but not the purchaser or other successor to Landlord's interest, from any
further liability or obligation to Tenant hereunder.

ARTICLE 21 - CONSENT BY LANDLORD
             -------------------

21.1 - Whenever, under this Lease, provision is made for Tenant

securing the written consent or approval by Landlord, such consent or approval
shall be in writing and may be withheld by Landlord in its sole discretion,
unless it is otherwise herein specifically provided that such consent shall not
unreasonably be withheld, conditioned or delayed.

                                      -23-
<PAGE>
 
ARTICLE 22 - SUBORDINATION
             -------------

22.1 - This Lease, and all rights of Tenant hereunder, are and shall be subject
to subordination in all respects to all present and future ground leases,
overriding leases and underlying leases of the Premises, Building or the Parcel
and to all present and future mortgages and building loan agreements, including
leasehold mortgages and building loan mortgages, which may now or hereafter
affect the same, to each and every advance made or to be made under such
mortgages, and to all renewals, modifications, replacements and consolidations
of such mortgages. This Section 22.1 shall be self-operative and no further
instrument of subordination shall be required.  In confirmation of such
subordination,  Tenant shall promptly execute and deliver at its own cost and
expense (as to the review,  execution  and  delivery  of  such  documentation)
any instrument (which shall be prepared at Landlord's expense), in recordable
form if required, that Landlord, the lessor of any such lease or the holder of
any mortgage or any of their respective successors in interest may require to
evidence such subordination. Notwithstanding anything to the contrary, the
foregoing provisions of this Section 22.1 shall be effective only in the event
that any such future mortgagee or holder of other encumbrance provides, or the
holder thereof agrees with Tenant, substantially as follows:  (a) That this
Lease is and shall be subject and subordinate to the mortgage insofar as it
affects the real property of which the Premises  form  a  part,  and  to  all
renewals,  modifications, consolidations, replacements and extensions thereof,
to the full extent of the principal sum secured thereby and interest thereon;
(b) That in the event it should become necessary to foreclose the mortgage, the
mortgagee thereunder will not join Tenant under this Lease in summary or
foreclosure proceedings so long as Tenant is not in default beyond any
applicable grace periods therefor under any of the terms, covenants or
conditions of this Lease; (c) That in the event the mortgagee shall, in
accordance with the foregoing, succeed to the interest of Landlord under this
Lease, the mortgagee agrees to be bound to Tenant under all of the terms,
covenants and conditions of this Lease, and Tenant agrees, from and after such
event,  to  attorn  to  the  mortgagee  and/or  purchaser  at  any foreclosure
sale of the Premises, all rights and obligations under this Lease to continue as
though the interest of Landlord had not terminated or such foreclosure
proceedings had not been brought, and Tenant shall have the same remedies
against the mortgagee for the breach of an agreement contained in this Lease
against Landlord if the mortgagee had not succeeded to the interest of Landlord;
provided, however, that the mortgagee shall not be (i) liable for any act or
omission of any prior landlord (including Landlord); or (ii) subject to any
offsets or defenses which Tenant might have against any prior landlord
(including Landlord); or (iii) bound by any Minimum Rent or Additional Rent
which Tenant might have paid for more than the current month to any prior
landlord (including Landlord); or (iv) bound by any amendment or modification of
the Lease made without  its consent.  Landlord agrees to use its best efforts to
obtain for Tenant from its present mortgagee and ground lessor a non-disturbance
agreement substantially in accordance with the foregoing and to promptly obtain
the consent of any mortgagee or ground lessor to any such modification.

22.2 - Any mortgage, including leasehold mortgages and building loan mortgages,
which may now or hereafter affect the Premises, may require that this Lease be
superior and have priority 

                                      -24-
<PAGE>
 
as to the mortgage in which event Tenant agrees to execute any instrument that
the holder of the mortgage may require to evidence same.

ARTICLE 23 - MECHANICS' LIENS
             ----------------

23.1 - Tenant shall not suffer any mechanic's lien to be filed against the
Premises by reason  of work,  labor,  services or materials performed or
furnished to Tenant or to anyone holding the Premises through or under Tenant.
If any such mechanic's lien shall at any time be filed against the Premises,
Tenant shall forthwith cause the same to be discharged of record by payment,
bond, order of a court of competent jurisdiction or otherwise, but Tenant shall
have the right to contest any and all such liens. If Tenant shall fail to cause
such lien to be discharged within thirty (30) days after being notified of the
filing thereof and before judgment or sale thereunder, then, in addition to any
other right or remedy of Landlord, Landlord may, but shall not be obligated to,
discharge the same by paying the amount claimed to be due or by bonding or other
proceeding deemed appropriate by Landlord, and the reasonable and provable
amount so paid  by  Landlord  and/or  all  costs  and  expenses,  including
reasonable attorney's fees, reasonably and provably incurred by Landlord in
procuring the discharge of such lien, shall be deemed to be Additional Rent.

ARTICLE 24 - NOTICES
             -------

24.1 - Any notice required or permitted under this Lease shall, unless
otherwise  specifically  provided  herein,  be  deemed sufficiently given or
served if sent by registered or certified mail return receipt requested, postage
prepaid, addressed to Tenant at 1 Research Way,  Princeton, New Jersey 08540 and
to Landlord at the address then fixed for the payment of rent.  Any such notice
shall be deemed given as of the date of mailing. Either party may by 15 days
notice at any time designate a different address to which notices shall
subsequently be mailed.

ARTICLE 25 - WAIVER OF TRIAL BY JURY
             -----------------------

25.1 - To the extent permitted by law, Landlord and Tenant hereby waive trial by
jury in any action brought by either against the other on any matter arising out
of or in any way connected with this Lease, the relationship of Landlord and
Tenant or Tenant's use or occupancy of the Premises including any claim or
injury or damage.

ARTICLE 26 - NO OTHER WAIVER OR MODIFICATIONS
             --------------------------------

26.1 - The failure of either party to insist in any one or more instances upon
the strict performance of any one or more of the agreements, terms, covenants,
conditions or obligations of this lease,  or to exercise  any right,  remedy or
election herein contained, shall not be construed as a waiver or relinquishment
for the future of the performance of such one or more obligations of this lease
or of the right to exercise such election, but the same shall continue and
remain in full force and effect with respect to any subsequent breach, act or
omission.

ARTICLE 27 - CURING TENANT'S DEFAULTS
             ------------------------

27.1 - If Tenant shall default in the performance of any covenant, agreement,
term, provision or condition herein contained, Landlord without thereby waiving
such default,  may  (but shall not be obligated to) perform the same for the
account of and at the expense of Tenant, without notice in a case of emergency
and in any other case if such default continues after thirty (30) days from the
date of the giving by Landlord to Tenant of written notice of such default.
Bills for any reasonable and necessary expense incurred by Landlord in
connection with any such performance by Landlord for the account of Tenant, and
reasonable and necessary bills for all costs, expenses and disbursements,
including (without being limited to) reasonable counsel fee, incurred in
collecting or endeavoring to collect the Minimum Rent or Additional Rent or
other charge or any part thereof or enforcing or endeavoring to enforce any
rights against Tenant under or in connection with this Lease, or pursuant to
law, including (without being limited to) any such cost,  expense  and
disbursement  involved  in  instituting  and prosecuting summary proceedings, as
well as bills for any property, material, labor or services provided, furnished
or rendered, or caused to be provided, furnished or rendered, by Landlord to
Tenant and any charges for other services incurred by Tenant under this Lease,
may be sent by Landlord to Tenant monthly, or immediately, at Landlord's option,
and shall be due and payable by Tenant in accordance with the terms of said
bills and if not paid when due, the amounts thereof shall immediately become due
and payable as Additional Rent under this Lease together with interest thereon
at a per annum rate equal to the sum of the Prime Rate as published in the Wall
Street Journal from time to time, plus two (2) percentage points from the date
the said bills should have been paid in accordance with their terms.

ARTICLE 28 - ESTOPPEL CERTIFICATE
             --------------------

28.1 - Tenant agrees,  at any time and from time to time, as requested by
Landlord, upon not less than ten (10) days prior notice, to execute and deliver
without cost or expense to the Landlord a statement certifying that this lease
is unmodified and in full force and effect (or if there have been modifications
that the same is in full force and effect as modified and stating the
modifications), certifying the dates to which the Minimum Rent and Additional
Rent have been paid, and stating whether or not, to the best knowledge of the
Tenant,  the Landlord is in default in performance of any of its obligations
under this lease, and if so, specifying  each  such  default  of  which  the
Tenant may have knowledge.

28.2 - It is intended that any such statement delivered to the Landlord pursuant

ARTICLE 29 - PARTIES BOUND
             -------------

29.1 - The obligations of this Lease shall bind and benefit the successors and
assigns of the parties with the same effect as if mentioned in each instance
where a party is named or referred to, except that no violation of the
provisions of Article 16 shall operate to vest any 

                                      -26-
<PAGE>
 
rights in any successor or assignee of Tenant and that the provisions of this
Article 29 shall not be construed as modifying the conditions of limitation
contained in Article 20. However, the obligations of Landlord under this Lease
shall not be binding upon Landlord herein named with respect to any period
subsequent to the transfer of its interest in the Parcel as owner or lessee
thereof and in the event of such transfer said obligations shall thereafter be
binding upon each transferee of the interest of Landlord herein named as such
owner or lessee of the Parcel, but only with respect to the period ending with a
subsequent transfer within the meaning of this Article 29 and such transferee,
by accepting such interest, shall be deemed to have assumed such obligations
except only as may be expressly otherwise provided in this Lease. A lease of
Landlord's entire interest in the Parcel as owner or lessee thereof shall be
deemed a transfer within the meaning of this Article 29. Any assignment of
Landlord's interest hereunder shall contain an assumption by Landlord's
successor on terms satisfactory to Landlord and Landlord's successor and not in
derogation of any rights of Tenant hereunder. Any assignment by Tenant shall be
governed by Article 14 hereof.

29.2 - Tenant shall look solely to Landlord's estate and property in the
Premises (or the proceeds thereof) for the satisfaction of Tenant's remedies for
the collection of a judgment  (or other judicial process) requiring the payment
of money by Landlord in the event of any default by Landlord hereunder, and no
other property or assets of Landlord or Landlord's partners or members shall be
subject to levy, execution or other enforcement procedure for the satisfaction
of Tenant's remedies under or with respect to either this Lease, the
relationship of Landlord and Tenant hereunder or Tenant's use and occupancy of
the Premises.

ARTICLE 30 - FORCE MAJEURE
             -------------

30.1 - Except as otherwise expressly provided herein, this Lease and the
obligations of Tenant to pay rent hereunder and perform all of  the  other
covenants,  agreements,  terms,  provisions  and conditions hereunder on the
part of Tenant to be performed shall in no wise be affected, impaired or excused
because Landlord is unable to fulfill any of its obligations under this Lease or
is unable to supply or is delayed in supplying any service, express or implied,
to be supplied or is unable to supply or is delayed in supplying any equipment
or fixtures if Landlord is prevented or delayed from so doing by reason of any
cause beyond Landlord's reasonable control, including, but not limited to, Acts
of God, strikes, labor troubles,  shortage  of  materials,  governmental
preemption  in connection with a national emergency or by reason of any rule,
order or regulation of any governmental agency or by reason of the conditions of
supply and demand which have been or are affected by war, hostilities or similar
emergency; provided that Landlord shall in  each  instance  exercise  reasonable
diligence  to  effect performance as soon as possible. It is agreed that the
Landlord shall not be required to incur any overtime or additional expenses in
Landlord's reasonable diligence to effect the performance of any of Landlord's
obligations in this lease contained.

ARTICLE 32 - DEFINITION OF LANDLORD
             ----------------------

32.1 - The term "Landlord" as used in this lease shall mean, at any given time
or from time to time as described in Section 29.1, the owner, or owners,
collectively or individually, for the time being of the fee or leasehold of all
or any portions of the Building. The necessary grammatical changes required to
make the provisions of this Lease apply in the plural sense where there is more
than one Landlord or Tenant and to either corporations,  associations,
partnerships or individuals, males or females, shall in all instances be assumed
as though in each case fully expressed.

ARTICLE 33 - TAXES ON TENANT'S PROPERTY
             --------------------------

33.1 - Tenant shall be liable for all taxes levied or assessed against any
personalty, fixtures and equipment installed by Tenant in the Premises. If any
such taxes are levied or assessed against Landlord, Tenant shall pay Landlord
upon demand taxes for which Tenant is liable as aforesaid.

ARTICLE 34 - ENVIRONMENTAL MATTERS
             ---------------------

34.1 - Tenant represents and warrants to Landlord that its Standard Industrial

Landlord of any changes in its SIC number. It is understood and agreed that
Tenant's operations constitute an "industrial establishment" as defined under
the Industrial Site Recovery Act, N.J.S.A. 13:1K-6, et seq. ("ISRA"). Tenant's
                                                    -- ---                    
use of the Premises shall be restricted to the classification number set forth
in this Section unless Tenant obtains Landlord's prior written consent to any
change in use of the Premises, which consent shall not be unreasonably withheld,
conditioned or delayed.  Prior to the Commencement Date, Tenant shall deliver to
Landlord an Affidavit of an officer of Tenant (the "Officer's Affidavit"),
setting forth a detailed description of the operations and processes Tenant
shall undertake at the Premises, organized in the form of a narrative report.
Such report need not detail any operations or processes which Tenant believes to
be proprietary in nature.  After the Commencement Date, Tenant shall notify
Landlord by way of the Officer's Affidavit as to any change in Tenant's
operations or processes which Tenant reasonably concludes would materially
affect the applicability of ISRA or similar legislation.  Tenant shall
supplement and update the Officer's Affidavit upon the written request for same
by Landlord, but no more often than annually.  In addition, Tenant shall
complete and promptly return to Landlord any and all surveys or questionnaires,
or similar inquiries, provided by Landlord to Tenant from time to time regarding
Tenant's use of Hazardous Materials in, on, under, at or about the Premises.

34.2 - Tenant shall, at Tenant's own expense, comply with any and all
legislation, rules and regulations in effect as of the date hereof  and
subsequent  thereto  relating  to  the  environment, including but not limited
to, ISRA, the  New Jersey Environmental Rights Act, N.J.S.A. 2A: 35A-1 et seq.;

promulgated thereunder and all substitutions thereof, as well as words of
similar purport or meaning referred to in any other Regulations, and any all
amendments thereto and the regulations and orders promulgated thereunder
(collectively, "Environmental Laws").  Tenant shall,  at Tenant's own expense,
make all submissions to, provide all information to, and comply with all
requirements of, the Industrial Site Evaluation Element ("the ISEE") of the New
Jersey Department of Environmental Protection ("NJDEP") or any other
governmental entity. Should the ISEE or any other division of NJDEP or any other
governmental entity determine that a cleanup plan be prepared or that any other
action be taken and that a cleanup of the Premises or other action be
undertaken, then Tenant shall, at Tenant's own expense, prepare and submit the
required plans and financial assurances, carry out the approved plans  or
required actions and obtain all  requisite approvals or consents of applicable
governmental entities. Tenant's obligations under this Article shall arise if
there is a "closing, termination or transferring" of operations (as such term is
defined in ISRA) or if any other triggering event or activity occurs which falls
under the purview of the statutes hereinbefore referred, including but not
limited to a transfer of ownership.  Tenant shall commence its submission to the
ISEE in anticipation of the end of the Lease Term no later than nine (9) months
prior to the expiration of the Lease Term.  Tenant shall obtain either (A) a
negative declaration approval; (B) final approval of cleanup; (C) a de minimis
quantity exemption; or (D) a letter of non-applicability (collectively referred
to as the "ISRA Clearance") from the NJDEP no later than thirty (30) days prior
to the expiration or earlier termination of this Lease.

34.3 - At no expense to Landlord, Tenant shall, in addition to the foregoing,
promptly provide all information reasonably requested by Landlord for
preparation of non-applicability affidavits or otherwise related to Tenant's
obligations hereunder. Tenant shall promptly sign such affidavits when requested
by Landlord. Tenant shall indemnity, defend and save harmless Landlord from and
against all fines, suits, procedures, claims and actions of any kind arising out
of or in any way connected with any spills or discharges of hazardous substances
or wastes in or about the Premises which occur during the  term of this  Lease;
and from all  fines,  suits, procedures, claims and actions of any kind or
nature arising out of Tenant's failure to provide all information, make all
submissions and take all actions required by the ISEE or any other division of
NJDEP or any other governmental entity. Tenant's obligations and liabilities
under this Article shall survive the expiration of this lease  term  and  shall
continue  so  long  as  Landlord  remains responsible  for the cleanup of  any
spills  or discharges of hazardous substances or wastes in or about the Premises
which occur during the term of this Lease or for any other fines, suits,
proceedings, claims or actions of any kind or nature whatsoever arising out of
Tenant's failure to provide all information, make, all submissions or take all
actions required by the ISEE, any other division of NJDEP or any other
governmental entity. Tenant's failure to abide by the terms of this Article
shall be restrainable by injunction.

34.4 - Landlord reserves the right from time to time, but not more than once a
year, except in the event of an emergency, during the term and any renewal term
hereof, at Tenant's reasonable cost and expense not to exceed $1500 per year,
to have the Premises inspected  by

rent and additional rent which Tenant otherwise would have paid as a holdover
tenant, until such time as Tenant obtains the ISRA Clearance, and during the
holdover period, all terms, conditions, and covenants of this Lease shall remain

rights, which option and rights shall be deemed null and void and of no further
force or effect.

34.6 -  If ISRA is not applicable to the closing, terminating or transferring of
operations by Tenant at the Premises, then Tenant shall, at Landlord's option,
hire a consultant satisfactory to Landlord to undertake at Landlord's direction,
sampling at the Premises sufficient to determine whether Tenant's operations
have resulted in a spill or discharge of Hazardous Materials in, on, under, at
or about the Premises.   Should the sampling reveal any spill or discharge of
Hazardous Materials, Tenant shall, at Tenant's own  cost and expense, promptly
undertake all action required by pursuant to all Environmental Laws, including
without limitation, posting all financial assurances required.

ARTICLE 35 - OPTION TO RENEW
             ---------------

35.1 - Provided that Tenant is not in default beyond any applicable grace
period, Tenant shall have an option to extend the term of the Lease, as amended
hereby, for two additional periods of five (5) years each commencing on the
expiration of the initial Term hereof and expiring five (5) years thereafter
(the "first renewal period") and commencing upon the expiration of the first
renewal period and expiring five (5) years thereafter (the "second renewal
period") upon the following terms and conditions:

          (a)  Tenant shall with respect to either renewal period exercise its
option to renew, if at all, by furnishing Landlord with written notice which
shall be received by Landlord at least nine (9) months prior to the initial
expiration date of the term of this lease, or the expiration of the first
renewal period, as the case may be, time being strictly of the essence. The
failure of Tenant to furnish such notice to Landlord in a timely manner as
provided shall constitute a waiver by Tenant of Tenant's option to renew the
term and/or first renewal period hereof and shall release Landlord from any
obligation to extend or further extend the term.

          (b)  All of the terms, covenants and conditions set forth in this
Lease and applicable to the initial term hereof shall apply to the first renewal
period and, as applicable, the second renewal period, except the provision of
this article with respect to the payment of Minimum Rent.

          (c)  The Minimum Rent payable during the first renewal period shall be
equal to the Minimum Rent payable immediately prior to the expiration of the
prior term, increased by fifty (50%) percent of the percentage increase between
the Consumer Price Index for December, 2001 and the Consumer Price Index for the
month of December, 2006 but in no event to exceed an increase of fifteen percent
(15%). In no event shall any adjustment based upon the Consumer Price Index
result in a reduction of the Base Rent. For the purposes of this Section, the
term "Consumer Price Index" means the "All Items" Index for the New York -
Northeastern New Jersey Area of the "Consumer Price Index for all Urban
Consumers" 

                                      -31-
<PAGE>
 
(Revised CPI-U) (1982-84=100) published by the Bureau of Labor Statistics of the
U.S. Dept. of Labor (or such successor index as may hereafter replace said
Consumer Price Index). If any revisions or changes in the base period of said
Consumer Price Index are made by the Bureau of Labor Statistics or its successor
during the interim period, the statistics used in such revised or changed Index
shall be corrected or weighted to correspond to the statistics used in the Index
in effect for the month immediately preceding the commencement of the term
hereof. In the event that the Consumer Price Index is discontinued and not
replaced with an equivalent index of an agency of the United States government,
the nearest equivalent consumer price index of any other public or private
organization in the United States, as determined by Landlord, shall be used for
any purpose for which the Consumer Price Index is to be used in this Lease.

          (d)  The annual Base Rent payable during the second renewal period
shall be equal to ninety-five percent (95%) or the prevailing fair market rental
paid for comparable flex/office space (totally excluding the value of all of
Tenant's Alterations in arriving at comparability) in the Princeton area (the
"Comparison Area"), as of the date which is six (6) months prior to the
expiration of the first renewal period, as mutually determined by the parties
using their best good faith efforts at the time of the exercise of the renewal
option hereunder. If the parties are unable to agree upon the fair market rental
of comparable space no later than five (5) months prior to the expiration of the
first renewal period, such one (1) month period representing the "Mutual
Agreement Period", said rental rate shall be determined by arbitration  in the
following manner:

               (i)   Landlord and Tenant shall each appoint one arbitrator who
shall, by profession, be an M.A.I. real estate appraiser, who shall have been
active over the five (5) year period ending on the date of Tenant's exercise of
said option in the appraisal of commercial and industrial properties in the
Comparison Area. Each such arbitrator shall be appointed within fifteen (15)
days after the expiration of the thirty (30) day mutual agreement period
described hereinabove.

               (ii)  The two arbitrators so appointed shall, within fifteen
(15) days of the date of the appointment of the last appointed arbitrator agree
upon and appoint a third arbitrator who shall be qualified based upon the same
criteria set forth hereinabove or qualification of the initial two arbitrators.

               (iii) The three arbitrators shall within thirty (30) days of the
appointment of the third arbitrator reach a decision and notify Landlord and
Tenant thereof.

               (iv)  The decision of the majority of the three arbitrators shall
be binding upon Landlord and Tenant. Failure of a majority of said arbitrators
to reach agreement shall result in the prevailing fair market rental for
comparable space in the Comparison Area being designated by averaging the
appraisals for the three arbitrators, ignoring for the purposes of such
averaging any portion of the high and low appraisal which is more than ten (10%)
percent in excess of or less than the middle appraisal.

               (v)  If either Landlord or Tenant fails to appoint an  arbitrator
within  the  time  period  in  subparagraph  (i) hereinabove, the arbitrator
appointed by one of them 

                                      -32-
<PAGE>
 
shall reach a decision, notify Landlord and Tenant thereof, and such
arbitrator's decision shall be binding upon Landlord and Tenant.

               (vi)  If the two arbitrators fail to agree upon and appoint a
third arbitrator, such matter shall be forthwith submitted to arbitration under
the provisions of the American Arbitration Association.

               (vii)  The cost of Landlord' arbitrator shall be borne by
Landlord, the cost of Tenant's arbitrator shall be borne by Tenant, and the cost
of the third arbitrator and any other costs of the arbitration shall be paid by
Landlord and Tenant equally.

               (viii) In no event shall the annual Base Rent payable during the
renewal period be less than the annual Base Rent payable immediately preceding
the renewal period of this Lease.

          (e)  The option to renew granted to Tenant is personal to Tenant and
may not be exercised or assigned,  voluntarily or involuntarily, by or to any
other person or entity other than Tenant.

ARTICLE 36 - RIGHT OF FIRST OFFER TO PURCHASE
             --------------------------------

36.1 - Provided that Tenant is not in default of any of its obligations or
covenants under this Lease, in the event Landlord desires to sell its leasehold
interest in the Premises, Landlord agrees that it will give Tenant notice of
Landlord's intention to list the Premises for sale, together with the terms upon
which Landlord intends to list the Premises ("Landlord's Offer Notice").  Tenant
shall be deemed to have waived its rights under this Section, unless Tenant
notifies Landlord within ten (10) days of Tenant's receipt of Landlord's notice
that Tenant is willing to purchase Landlord's interest in the Premises upon the
terms similar to those set forth in Landlord's notice. In the event Tenant
notifies Landlord of its willingness to purchase the Premises, Tenant shall have
twenty (20) days from Tenant's receipt of  Landlord's  notice  to  negotiate
with  Landlord  a  purchase agreement acceptable to both parties.  In the event
that the parties cannot reach agreement, Landlord shall be entitled to market
the Premises to others, provided however that if Tenant notified Landlord of its
willingness to purchase the Premises and Landlord and Tenant failed to negotiate
an acceptable purchase agreement, and thereafter Landlord elects to market the
Premises for less than ninety (90%) percent of the price which Tenant had been
willing to pay as its final offer in the preceding negotiations, then Landlord
must again provide Tenant with Landlord's Offer Notice, revised to reflect the
revised amount for which the Premises will be marketed (the "Revised Notice").
Thereafter Tenant shall have a period of ten (10) days from the receipt of the
Revised Notice to indicate in writing to Landlord its  willingness to match the
terms of such offer, and Tenant shall have twenty (20) days from Tenant's
receipt of  Landlord's  Revised Notice to negotiate with Landlord a purchase
agreement acceptable to both parties.  In the event that the parties cannot
reach agreement, Landlord shall be entitled to market the Premises to others,
provided that if Landlord thereafter desires to market the Premises for less
than ninety (90%) percent of the price which Tenant had been willing to pay as
its final offer in the immedaitely preceding negotiations, Landlord shall be
required to again offer the Premises to Tenant pursuant to the above provisions.
Nothing contained herein shall be deemed to grant Tenant an option to 

                                      -33-
<PAGE>
 
purchase the Premises or a right of first refusal, nor to impose upon Landlord
any obligation or liability to enter into an agreement with Tenant for the sale
of the Premises.

ARTICLE 37 - SECURITY
             --------

37.1 - Tenant shall obtain at its sole cost and expense, and shall deposit with
Landlord at the time of the execution of this Lease, an unconditional, clean,
irrevocable and assignable letter of credit (the "Letter of Credit"), issued by
a bank satisfactory to Landlord with banking operations in the State of New
Jersey, in form and substance satisfactory to Landlord, in the amount (in United
States dollars) of $1,000,000.00 as security for the faithful performance and
observance by Tenant of any terms, provisions and conditions of this Lease, the
nonperformance of which would obligate Landlord to incur any financial
obligations, (including but not limited to, Tenant's financial obligations for
Rent and for the costs of restoration of the Premises upon the expiration or
earlier termination of the Term). It is agreed that in the event Tenant defaults
in respect of any of the terms,  provisions  and conditions of this Lease,
including but not limited to the payment of Fixed Rent and Additional Rent,
Landlord may use, apply or retain the whole or any part of the security so
deposited to the extent required for the payment of any Fixed Rent, Additional
Rent, assessments and levies or any other sum as to which Tenant is in default,
or for any sum which Landlord may expend or may be required to expend by reason
of Tenant's default in respect of any of the terms, covenants and conditions of
this Lease, including but not limited to, any damages or deficiency in the
reletting of the Premises, whether such damages or deficiency accrued before or
after summary proceedings or other re-entry by Landlord. The Letter of Credit
shall (i) specify that it is irrevocable and, at the direction of Landlord,
assignable to Landlord's successors and assigns of Landlord's interest under
this Lease, at Tenant's sole cost and expense, (ii) be addressed to Landlord,
(iii) be payable upon each presentation of a sight draft,  accompanied by a
statement signed by an authorized official of Landlord certifying that Tenant is
in default hereunder, and (iv) be payable from the date of issuance up to a date
which is not less than one year from the date of issuance.  Landlord  shall
deliver  to  Tenant  a  copy  of  the certificate of Tenant's default presented
by Landlord in connection with any draw upon the Letter of Credit. Tenant shall,
not later than thirty (30) days prior to the expiration of the Letter of Credit
or any replacements, substitutions or extensions thereof, as the case may be,
furnish Landlord with a new letter of credit in accordance with the foregoing or
an extension of the Letter of Credit then in effect. Upon an event of default
under this Lease or if Tenant fails to furnish a new letter of credit or an
extension as aforesaid within thirty (30) days prior to the expiration of the
Letter of Credit or any replacement or extension thereof, Landlord may
immediately draw upon the Letter of Credit in accordance with the terms hereof
and apply the proceeds thereof in accordance with the provisions of this Section
37.1.

ARTICLE 38 - GENERAL PROVISIONS
             ------------------

Notice of Default served upon the Landlord, provided that prior to such notice
tenant has been notified, in writing, (by way of Notice of Assignment of Rents
and Leases, or otherwise) of the address of such mortgagees. Tenant further
