                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and Notes thereto
appearing elsewhere in this Prospectus.
 
                                  THE COMPANY
 
  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 E/1/, 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)/Abelcet(TM) 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"). See
"Risk Factors--Early Stage of Commercialization" and "--Regulation."
 
  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 E/1/ ("PGE/1/"), 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
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.

                                  RISK FACTORS
 
  The following risk factors should be considered carefully in addition to the
other information contained in this Prospectus before purchasing the Common
Stock offered hereby:
 
  Early Stage of Commercialization. The Company has not generated any
significant revenues from the sale of its products. None of the Company's
products is yet approved for sale in the United States, and the sale of
Abelcet (TM) has just commenced in the United Kingdom. Each product must be
clinically tested, approved for use by appropriate government agencies and
manufactured in commercial quantities before marketing can begin. While the
Company has filed marketing applications in various foreign countries with
respect to Abelcet (TM), there can be no assurance that such applications will
be accepted or, if approved, that there will not be burdensome restrictions
which might lead the Company to refrain from selling Abelcet (TM) in some or
all of these jurisdictions. 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's long-term viability and growth will depend on successful
commercialization of products resulting from its research activities. No
assurance can be given that any of the Company's products under development
will be successfully commercialized or that required regulatory approvals will
be obtained. In addition, if the Company's revenues fail to grow at a rate
sufficient to absorb the increased expenses associated with the
commercialization of its products, or if it is unable to add or assimilate
qualified personnel needed for such commercialization, its results could be
adversely affected. See "Business--Product Development," "--Manufacturing" and
"--Marketing Strategy."
 
  History of Operating Losses and Accumulated Deficit. The Company has incurred
losses in each year since its inception and anticipates that operating losses
will continue for at least two years. The Company's accumulated deficit at
December 31, 1994 was approximately $108,859,000. The Company will need to
commit significant financial and other resources to clinical trials of its
self-funded products and to the preparation for commercial marketing of
ABLC (R) in the United States should approval be received from the FDA. See
"Selected Consolidated Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
  Need for Additional Financing and Uncertain Access to Capital Funding. The
Company's capital requirements depend upon numerous factors, including the
progress of the Company's product development programs; the time required to
obtain regulatory approvals; the resources that the Company devotes to the
development, manufacturing and marketing of self-funded products; and the
demand for its products if and when approved. It is possible that the Company
may require additional financing to complete the clinical testing and to
manufacture and to market its self-funded products. There can be no assurance
that such financing will be available or will be available on acceptable terms.
See "Use of Proceeds" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
  Limited Manufacturing Capabilities. The Company currently intends to
manufacture its self-funded products. TLC D-99, being developed by the Company
under a licensing and development agreement with Pfizer, may be manufactured by
the Company or Pfizer, at Pfizer's option. TLC I-16, which is being developed
under a collaborative research and development agreement with Schering AG, is
to be manufactured by the Company. In order to be successful, the Company's
products must be manufactured in commercial quantities, in compliance with
regulatory requirements, at an acceptable cost and with sufficient stability.
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 Abelcet (TM) to satisfy initial commercial demand, but may not be
capable of producing quantities of product sufficient to satisfy demand when
ABLC (R)/Abelcet (TM) is
 
                                       5
<PAGE>
 
fully commercialized. The Company owns a manufacturing facility in
Indianapolis, Indiana for the manufacture of its commercial products on a scale
the Company believes to be sufficient to meet worldwide demand and has begun
the refitting of this facility to manufacture ABLC (R)/Abelcet (TM). However,
substantial expenditures will be required to complete the refitting of the
facility and to install and validate the processing and other equipment
necessary for the manufacture of the Company's products in this facility and to
hire and train new employees to operate the facility. See "Business--
Manufacturing."
 
  Limited Marketing Capabilities. Although the Company intends to market
certain of its products in the United States and certain other countries
through its own sales force if and when regulatory approval for those products
is obtained, it currently has limited marketing and sales staff, and
significant additional expenditures, management resources and time would be
required to develop such sales forces. There can be no assurance that the
Company will be able to establish such sales forces or be successful in gaining
market acceptance for its products. To the extent that the Company determines
not to, or is unable to, establish such sales forces, it will be dependent on
third parties for the marketing and distribution of its products. See
"Business--Marketing Strategy."
 
  Technological Change; Competition. The biopharmaceutical industry is
characterized by extensive research and development efforts, and is subject to
rapid and significant technological change. The Company has numerous
competitors, including major pharmaceutical and chemical companies, specialized
biotechnology firms, other companies developing liposomes or other lipid-based
products, universities and other research institutions. New developments in
lipid and liposome research as well as new pharmaceutical products and other
drug-delivery systems are expected to continue at a rapid pace. Competitors may
succeed in developing technologies and products that are more effective than
any that are being developed by the Company or that would render the Company's
technology and products non-competitive. Many of these competitors have
substantially greater financial and technical resources and production and
marketing capabilities than the Company. In addition, many of the Company's
competitors have significantly greater experience than the Company in
preclinical testing and human clinical trials of new or improved pharmaceutical
products and in obtaining FDA and other regulatory approvals on products for
use in health care. The Company is aware of various products under development
or manufactured by competitors that are used for the prevention, diagnosis or
treatment of certain diseases the Company has targeted for product development,
some of which use therapeutic approaches that compete directly with certain of
the Company's product candidates. The Company's competitors may succeed in
obtaining FDA approval for products more rapidly than the Company, which could
adversely affect the Company's ability to develop and market its products. If
the Company commences significant commercial sales of its products, it will
also be competing with respect to manufacturing efficiency and marketing
capabilities, areas in which the Company has limited or no experience. See
"Business--Competition."
 
  Regulation. Human therapeutic products, vaccines and in vivo diagnostic
products are subject to rigorous preclinical and clinical testing and approval
by the FDA and comparable agencies in other countries and, to a lesser extent,
by state regulatory authorities prior to marketing. The process of obtaining
such approvals, especially for human therapeutic products, is likely to take a
number of years and will involve the expenditure of substantial resources. If
the FDA requests additional data, these time periods can be materially
increased. Even after such additional data is submitted, there can be no
assurance of obtaining FDA approval. In addition, product approvals may be
withdrawn or limited for noncompliance with regulatory standards or the
occurrence of unforeseen problems following initial marketing. The Company has
not sought or received regulatory approval in the United States for the
commercial sale of any of its principal products or for any manufacturing
processes or facilities. The Company and its licensees may encounter
significant delays or excessive costs in their respective efforts to secure
necessary approvals or
 
                                       6
<PAGE>
 
licenses. Future federal, state, local or foreign legislative or administrative
acts could also prevent or delay regulatory approval of the Company's or its
licensees' products. There can be no assurance that the Company or its
collaborative partners will be able to obtain the necessary approvals for
manufacturing or marketing of the Company's products or that the clinical data
they obtain in clinical studies will be sufficient to establish the safety and
effectiveness of the products. Failure to obtain or maintain requisite
governmental approvals, or failure to obtain approvals of the clinical intended
uses requested, could delay or preclude the Company or its licensees from
further developing particular products or from marketing their products, or
limit the commercial use of the products and thereby have a material adverse
effect on the Company's liquidity and financial condition. The Company has
limited experience in conducting and managing clinical testing and in preparing
applications necessary to gain governmental approvals. The Company has not yet
submitted an NDA in the United States, and no assurance can be given with
respect to any NDA submitted to the FDA by the Company that such NDA will be
accepted for consideration, that it will be promptly reviewed, that the FDA
will find the data submitted adequate or that such NDA will ultimately be
approved.
 
  Many products for the treatment of conditions such as systemic fungal
infections, ARDS, sepsis, heart attack and cancer which have been tested in
clinical trials have failed to meet the standards of the FDA. To the knowledge
of the Company, the FDA has not yet granted marketing approval for any human
pharmaceutical product based on lipid or liposome technologies of the types
employed by the Company. In addition, no therapeutic products based upon these
technologies are commercially available in the United States. Consequently, the
ability to secure regulatory approvals for the Company's products and the
ultimate commercial potential of these products cannot currently be assured.
See "Business--Governmental Regulation."
 
  Patents and Proprietary Technology. The Company has a number of United States
and foreign patents and patent applications relating to various aspects of
lipid and liposome technologies. The patent position of biopharmaceutical
companies generally is highly uncertain and involves complex legal and factual
questions. The Company currently holds 54 United States patents and may be
issued additional patents in the future. There can be no assurance that any
patents will afford the Company commercially significant protection for its
proprietary technology or have commercial application, and litigation may be
necessary to determine the validity and scope of the Company's proprietary
rights. Moreover, the patent laws of foreign countries and the enforcement of
such laws may afford less protection than comparable U.S. laws. The Company may
not have adequate funds to defend or prosecute the patents in question.
 
  Other public and private concerns, including universities, may have filed
applications for, or have been issued, patents with respect to technology
potentially useful or necessary to the Company. If any of the Company's
proprietary technology in these areas were to conflict with the rights of
others, the Company's ability to commercialize products using such technologies
could be materially and adversely affected. 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.
 
  In addition, the Company relies on unpatented proprietary know-how, and there
can be no assurance that others will not obtain access to or independently
develop such know-how. Although employees, corporate sponsors, research
partners and consultants are not given access to proprietary know-how of the
Company until they have executed confidentiality agreements, these agreements
may not provide meaningful protection for the Company's proprietary know-how in
the event of any unauthorized use or disclosure of such know-how. See
"Business--Patents and Proprietary Technology."
 
                                       7
<PAGE>
 
  Product Liability. The testing, manufacturing and marketing of the Company's
products entail an inherent risk of adverse events that could expose the
Company to product liability claims. The Company has obtained insurance of
$10,000,000 against the risk of product liability claims. However, there is no
guarantee that this insurance will be adequate, that the amount of this
insurance can be increased, or that the policy can be renewed. Moreover, the
amount and scope of any coverage obtained may be inadequate to protect the
Company in the event of a successful product liability claim. See "Business--
Product Liability."
 
  Dependence on Key Personnel and Consultants. The Company's ability to
successfully develop marketable products and to maintain a competitive position
will depend in large part on its ability to attract and retain highly qualified
scientific and management personnel and to develop and maintain relationships
with leading research institutions and consultants. Competition for such
personnel and relationships is intense, and there can be no assurance that the
Company will be able to continue to attract and retain such personnel. See
"Business--Human Resources" and "--Competition."
 
  Dependence on Corporate Partners. The Company's revenues to date have been
primarily generated by payments under collaborative research and development
contracts and from interest on invested cash. The Company could be adversely
affected if either Pfizer or Schering AG exercised its right to terminate its
respective agreement. In such event, the Company might be required to seek
alternate financing in order to continue the development and testing of the
products that are the subject of such research and development agreements. If
the Company's working capital or alternate financing were inadequate to fund
further development or testing, then development of these products might be
delayed or cancelled. In the case of TLC I-16, should the agreement be
cancelled by Schering AG, the Company may not be able to obtain supplies of a
proprietary raw material owned by Schering AG and may be required to undertake
the development of TLC I-16 with an alternative raw material. Assuming the
Company and its corporate partners are able to develop successfully one or more
of the products currently under development under these agreements, the
Company's revenues from sales of these products will depend in large part upon
the efforts and abilities of its corporate partners, in some cases, to perform
clinical testing, to obtain regulatory approvals, to market and, in the case of
TLC D-99, to manufacture the Company's products. The amount and timing of
resources devoted to these activities will not be completely within the
Company's control. The Company's partners will have certain discretion in
deciding whether or not to commercialize the products, and may develop or
market products competitive with those of the Company. While the Company
believes its corporate partners have or will have an economic motivation to
succeed in performing their obligations under such agreements, there can be no
assurance that the corporate interests and motivations of these partners will
remain consistent with those of the Company. In March, 1995, Wyeth-Ayerst
Laboratories, a division of American Home Products Corporation ("Wyeth-
Ayerst"), to whom the Company had licensed the use of TLC A-60 as an adjuvant
for an influenza vaccine, advised the Company that it intends to return its
rights to TLC A-60 to the Company. If and when sales of products developed with
the Company's corporate partners commence, the Company's revenues with respect
to such products will be limited to royalties based on product sales and/or
revenues from manufacturing those products. See "Business--Product
Development."
 
  Uncertainty of Health Care Reimbursement. The Company's ability to earn
sufficient returns on its products may depend in part on the extent to which
reimbursement for the costs of such products and related treatments will be
available from government health administration authorities, private health
coverage insurers and other organizations. If purchasers or users of the
Company's products are not entitled to adequate reimbursement for the cost of
using such products, they may forego or reduce such use. Significant
uncertainty exists as to the reimbursement status of
 
                                       8
<PAGE>
 
newly approved health care products, and there can be no assurance that
adequate third party coverage will be available.
 
  Dependence Upon Suppliers. The Company currently relies on a limited number
of suppliers to provide the materials used to manufacture its products, certain
of which materials are purchased only from one supplier. Although the Company
believes that it can obtain adequate commercial quantities of necessary
materials and that it could develop alternative sources of supply for most or
all of the materials used to manufacture its products, there can be no
assurance that the Company would be able to access such sources within a
reasonable period of time or at commercially reasonable rates. In particular,
the Company presently acquires amphotericin B, a principal ingredient in
ABLC(R)/Abelcet (TM), from one supplier on what the Company believes are
favorable terms. The loss of this supplier could have a material adverse effect
on the Company, either because of a delay or inability in obtaining an
alternate supplier or because of the impact of obtaining the product at a
significantly higher cost. Regulatory requirements applicable to pharmaceutical
products tend to make the substitution of suppliers more costly and time-
consuming. The unavailability of adequate commercial quantities, the inability
to develop alternative sources, a reduction or interruption in supply or a
significant increase in the price of materials could have a material adverse
effect on the Company's ability to manufacture and market its products.
 
  International Sales. The Company believes that sales outside of the United
States will initially represent a significant portion of the Company's business
if marketing approvals are received from countries outside the United States
more quickly than approvals from the FDA. There are significant challenges and
risks to the Company associated with conducting business in some foreign
countries, including, but not limited to, disparate governmental regulation of
pharmaceutical products and uncertain intellectual property protections.
Although the Company has established an office in London, England, it does not
have extensive experience in international sales. The Company's international
business and financial performance could also be adversely affected by such
matters as fluctuations in currency exchange rates, currency controls, tariff
regulations, foreign duties and taxes, pricing controls and regulations and
difficulties in obtaining export licenses.
 
  Volatility of Stock Price. There has been a history of significant volatility
in the market prices for shares of companies in a similar stage of development
to that of the Company, and the market price of the shares of the Company's
Common Stock has been volatile. Factors such as announcements of technological
innovations or new commercial products by the Company or its competitors,
governmental regulation, decisions made by corporate sponsors under
collaborative research and development agreements regarding product development
activities, developments relating to regulatory approvals, developments or
disputes relating to patent or proprietary rights, as well as period-to-period
fluctuations in revenues and financial results, may have a significant impact
on the market price of the Company's Common Stock. See "Price Range of Common
Stock and Dividend Policy."
 
  Dilution. Purchasers of shares of Common Stock in this offering will
experience immediate and substantial dilution of net tangible book value per
share. Additional dilution will occur upon the exercise of outstanding stock
options.
 
                                  THE COMPANY
 
  The Company's principal executive offices are located at One Research Way,
Princeton Forrestal Center, Princeton, New Jersey 08540 and its telephone
number is (609) 452-7060. Unless the context otherwise requires, the "Company"
refers to The Liposome Company, Inc. and its wholly-owned subsidiaries.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 3,000,000 shares of
Common Stock offered by the Company hereby at an assumed public offering price
of $11.125 per share are estimated to be $31,000,000 ($35,705,875 if the
Underwriters' over-allotment option is exercised in full).
 
  The Company anticipates that the proceeds of this offering, in conjunction
with the Company's current working capital, will be used for (i) the
commercialization of ABLC (R)/Abelcet (TM), including the expansion of
manufacturing, marketing and distribution capabilities, the refitting of the
Company's manufacturing facility in Indianapolis, Indiana for the manufacture
of ABLC (R) and the on-going clinical testing of ABLC (R), (ii) the development
and clinical testing of TLC C-53 and the Company's other self-funded products,
(iii) research activities and (iv) other general corporate purposes. The
Company is unable to specify the amount that it will spend on such programs
because such amounts will vary depending on numerous factors, including the
progress of the Company's development efforts and regulatory approvals. Such
expenditures are likely to be extensive and may exceed the amount of proceeds
available from this offering. The Company has begun to refit its manufacturing
facility in Indianapolis and expects that this facility will become operational
in 1996. The initial plan of activity includes design work and construction of
improvements to the facility necessary for a modern manufacturing facility,
renovation and validation of critical building systems, purchase and
installation of product specific processing equipment for the manufacture of
ABLC (R), and training and hiring of employees. The Company anticipates that
this phase of construction and validation work and related start-up
expenditures will cost approximately $11,000,000 to $13,000,000. Additional
costs would have to be incurred for the product specific processing equipment
necessary for the production of the Company's other products if and when
decisions are made to proceed with such commercial manufacturing.
 
  The Company has considered in the past, and is continuing to consider,
alternative sources of financing, including financing specific to a particular
development project or projects. If such financing involves one of the
Company's lead products, the Company will use the portion of the proceeds of
this offering that would otherwise have funded such product for other purposes
described above. Pending such uses, the net proceeds will be invested in
investment grade interest-bearing securities.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  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 an 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 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
E/1/, 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)/Abelcet(TM) 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
Abelcet(TM) 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.
 
  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
 
                                      14
<PAGE>
 
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)/Abelcet (TM), 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.
 
  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.
 
                                       15
<PAGE>
 
  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 Abelcet(TM). By year-end
1994, the Company had filed applications to market Abelcet(TM) 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 Abelcet(TM) 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 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, product
sales and proceeds from this offering. 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.

                                   BUSINESS
 
OVERVIEW
 
  The Liposome Company, Inc. 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 an 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 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 PGE/1/, for the treatment of 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 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)/Abelcet (TM) 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 FDA. See "Risk Factors--Early Stage
of Commercialization" and "-- Regulation."
 
  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 PGE/1/, 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 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 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 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)/Abelcet(TM), TLC D-99 and TLC C-53.
 
  ABLC(R) (Abelcet(TM) 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
Abelcet(TM) from the Medicines Control Agency of the United
 
                                       20

Kingdom. The indications for which Abelcet(TM) was approved were 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. 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)/Abelcet(TM). 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.
 
  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.
 
                                       21
<PAGE>
 
  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 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
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
 
                                      23
<PAGE>
 
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
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 PGE/1/ 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
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
Abelcet(TM) 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.
 
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.
 
                                       27
<PAGE>
 
  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 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,
 
                                       28
<PAGE>
 
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.
 
FACILITIES
 
  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
portions of the facility. See "Manufacturing" and "Management's Discussion and
Analysis of Financial Conditions and Results of Operations--Liquidity and
Capital Resources."

SCIENTIFIC ADVISORY BOARDS
 
  The Company has two scientific advisory boards consisting of prominent
scientists who are experts in the fields of cancer, inflammation or cell
adhesion and who the Company believes may make a contribution to the
development of the Company's business in those areas. The scientific advisory
boards review and monitor the Company's research and technical progress, advise
the Company of advances in their fields, assist in identifying specific product
opportunities and aid in recruiting personnel and procuring research contracts.
Members of the scientific advisory boards meet individually and as a group with
management of the Company periodically.

                          DESCRIPTION OF CAPITAL STOCK
 
  The Company is authorized to issue 60,000,000 shares of Common Stock, $.01
par value per share, and 2,400,000 shares of Serial Preferred Stock, $.01 par
value per share. As of January 31, 1995, there were 24,018,309 shares of Common
Stock outstanding held of record by approximately 1,480 stockholders. As of
January 31, 1995, there were 2,760,000 Depositary Shares ("Depositary Shares")
outstanding, each of which represents one-tenth of a share of Series A
Cumulative Convertible Exchangeable Preferred Stock (the "Series A Preferred
Stock").
 
COMMON STOCK
 
  Holders of Common Stock are entitled to one vote for each share held of
record on any matters voted upon by stockholders.
 
  Subject to preferences that may be applicable to any outstanding preferred
stock, holders of Common Stock are entitled to receive ratably such dividends
as may be declared by the Board of Directors out of funds legally available
therefore. See "Price Range of Common Stock and Dividend Policy." Upon the
liquidation, dissolution or winding up of the Company, holders of Common Stock
are entitled to receive all assets remaining after payment of liabilities and
the liquidation preferences of any outstanding preferred stock. The shares of
Common Stock have no conversion, preemptive or other rights to subscribe for
additional shares and are not subject to redemption or sinking fund provisions.
Outstanding shares of Common Stock are, and the shares of Common Stock offered
by the Company hereunder when issued will be, fully paid and nonassessable.
 
PREFERRED STOCK AND DEPOSITARY SHARES
 
  The Certificate of Incorporation of the Company provides that the Board of
Directors of the Company has the authority, without further action of
stockholders, to issue up to 2,400,000 shares of its Serial Preferred Stock in
one or more series, and to fix the designations, rights, preferences, and
restrictions and the number of shares constituting any series. The rights of
the holders of Common Stock will be subject to, and may be adversely affected
by, the rights of holders of any Serial Preferred Stock that may be issued in
the future. The issuance of shares of Serial Preferred Stock could have the
effect of delaying, deferring additional or preventing a change in control of
the Company. The Company has no current plans to issue any shares of Serial
Preferred Stock.
 
  Each Depositary Share is convertible at the option of the holder at any time
into shares of Common Stock at an initial conversion price of $12.85 per share
of Common Stock, which is equivalent to a conversion rate of 1.9455 shares of
Common Stock for each Depositary Share, subject to adjustment in certain
events. Dividends on the Series A Preferred Stock are cumulative from the date
of original issue at an annual rate of 7 3/4% per share (equivalent to $1.9375
per annum per Depositary Share) and its liquidation preference is $25.00 per
Depositary Share, plus accrued and unpaid dividends. The Series A Preferred
Stock may not be redeemed prior to January 15, 1996. On or after such date, the
Series A Preferred Stock may be redeemed initially at an amount equivalent to
$26.40 per Depositary Share and thereafter at prices declining to an amount
equivalent to $25.00 per Depositary Share on and after January 15, 2003, plus,
in each case, all accrued and unpaid dividends. The Series A Preferred Stock is
exchangeable in whole, but not in part, at the option of the Company on any
dividend payment date beginning on January 15, 1996, for the Company's Series A
Convertible Subordinated Debentures due 2003 (the "Debentures") at the rate of
$250.00 principal amount of Debentures for each share of Series A Preferred
Stock, provided that all accrued and unpaid dividends, if any, on the Series A
Preferred Stock have been paid. Upon certain corporate changes or ownership
changes of the Company, holders of the Series A Preferred Stock will have
special rights to convert their shares, subject to cash redemption at the
option of the Company. Except as required by law or with respect to the
creation or amendment of senior classes of preferred stock, the holders of
Series A Preferred Stock are not entitled to any
 
                                       36
<PAGE>
 
voting rights unless the equivalent of six quarterly dividend payments thereon
are in arrears, in which case the number of directors of the Company will be
increased by two and the holders of Series A Preferred Stock, voting separately
as a class with the holders of shares of any other series of parity preferred
stock upon which like voting rights have been conferred and are exercisable,
will be entitled to elect two directors until the dividend arrearage has been
paid.
 
TRANSFER AGENT AND REGISTRAR
 
  Midlantic Bank acts as transfer agent and registrar for the Common Stock.

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel. The nature
of the Underwriters' obligation is such that they are committed to purchase all
shares of Common Stock offered hereby if any of such shares are purchased.
 
  The Underwriters propose to offer the shares of Common Stock directly to the
public at the offering price set forth on the cover of this Prospectus and to
certain dealers at such price less a concession not in excess of $    per
share. The Underwriters may allow and such dealers may reallow a concession not
in excess of $    per share to certain other dealers. After the public offering
of the shares of Common Stock, the offering price and other selling terms may
be changed by the Underwriters.
 
  The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to 450,000
additional shares of Common Stock at the public offering price, less the
underwriting discount, set forth on the cover page of this Prospectus. To the
extent that the Underwriters exercise this option, each of the Underwriters
will have a firm commitment to purchase approximately the same percentage
thereof which the number of shares of Common Stock to be purchased by it shown
in the above table bears to the total number of shares of Common Stock offered
hereby. The Company will be obligated, pursuant to the option, to sell such
shares to the Underwriters to the extent the option is exercised. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of the shares of Common Stock offered hereby.
 
  The offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the offering without notice. The Underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
  Certain officers of the Company, who own approximately 68% of the shares of
Common Stock held by the executive officers and directors of the Company, have
agreed that they will not, without Hambrecht & Quist's prior written consent,
offer, sell, or otherwise dispose of any shares of Common Stock, options or
warrants to acquire shares of Common Stock or securities exchangeable for or
convertible into shares of Common Stock owned by them for a period of 90 days
following the commencement of the offering. The Company has agreed that it will
not, without Hambrecht & Quist's prior written consent, offer, sell or
otherwise dispose of any shares of Common Stock,
 
                                       38
<PAGE>
 
options or warrants to acquire shares of Common Stock or securities
exchangeable for or convertible into shares of Common Stock for a period of 90
days following the commencement of the offering, except that the Company may
issue shares, options or warrants to (i) consultants and grantors of licensing
rights and (ii) directors, officers and employees in accordance with the
Company's customary practices.
 
  In general, the rules of the Commission will prohibit the underwriters from
making a market in the Company's Common Stock during the "cooling off" period
immediately preceding the commencement of sales in the offering. The Commission
has, however, adopted exemptions from these rules that permit passive market
making under certain conditions. These rules permit an underwriter to continue
to make a market subject to the conditions, among others, that its bid not
exceed the highest bid by a market maker not connected with the offering and
that its net purchases on any one trading day not exceed prescribed limits.
Pursuant to these exemptions, the Underwriters, selling group members (if any)
or their respective affiliates may engage in passive market making in the
Company's Common Stock and the Depositary Shares representing Series A
Preferred Stock during the cooling off period.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed upon
for the Company by Dewey Ballantine, 1301 Avenue of the Americas, New York, New
York 10019 and for the Underwriters by Shearman & Sterling, 599 Lexington
Avenue, New York, New York 10022.

                       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

                  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, 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 an 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 a corporate sponsor primarily as a first line treatment of
metastatic breast cancer. TLC C-53, liposomal prostaglandin E/1/, 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.
 
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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
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 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.
 
2. STOCKHOLDERS' EQUITY:
 
PREFERRED STOCK:
 
  In January 1993, the Company completed an offering of 2,760,000 Depositary
Shares, each of which represents one-tenth of a share of Series A Cumulative
Convertible Exchangeable Preferred Stock carrying a 7 3/4% dividend rate. The
liquidation value is $25.00 per Depositary Share, plus accrued and unpaid
dividends. Each Depositary Share is convertible at any time into shares of the
Company Common Stock at a conversion price of $12.85 per share of Common Stock,
which is equivalent to a conversion rate of 1.9455 shares of Common Stock for
each Depositary Share. 5,369,580 shares of Common Stock are reserved for such
conversion. The proceeds to the Company were $66,240,000 net of underwriter
fees. Additional stock issuance costs, including professional, registration,
filing and printing fees of approximately $505,000 were incurred in connection
with this offering.

Preferred Stock at a prorated dividend rate of $.484375 per Depositary Share.
Dividend payments in 1994 and 1993 totaled $5,348,000 and $4,011,000,
respectively. An additional dividend payment of $1,337,000 was paid on January
16, 1995 to stockholders of record on January 2, 1995.

the sale.
 
3. STOCK OPTION PLANS:
 
  The Company has several stock option plans available for the issuance of
incentive stock options and non-qualified stock options ("NQSO"). These options
are designed to attract and retain key employees, directors and consultants. As
of December 31, 1994, the Company had outstanding grants of 4,226,105 shares
and 1,455,808 shares available for grants, totaling 5,671,913 shares of Common
Stock reserved for stock option grants.
 
  Options are granted at fair market value. These options generally become
exercisable in ratable installments over a five-year period. Options under the
1991 Non-Employee Directors NQSO Plan ("Directors' Plan") are automatically
granted upon appointment to the Board of Directors and annually on July 1 of
each year to such non-employee Directors. Such initial grants vest over a five
year period and subsequent annual grants vest in one year. Activity under all
stock option plans for 1992, 1993 and 1994 is summarized as follows:

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.
 
  Temporary differences and carryforwards which give rise to the deferred tax
assets and liabilities at December 31, 1994 are as follows:

1996 through 2009. The timing and manner in which these losses are used may be
limited as a result of certain ownership changes which occurred as provided by
IRS Regulations under Section 382.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law, among other things, and
subject to certain conditions, authorizes the Company to indemnify its officers
and directors against certain liabilities and expenses incurred by such persons
in connection with claims made by reason of their being such an officer or
director. The By-laws of the Company provide for indemnification of its
officers and directors to the full extent authorized by law.
 
  The Company's Certificate of Incorporation provides that no director of the
Company shall be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty or loyalty to the Company
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any
transaction from which the Director derived any improper personal benefit. Any
repeal or modification of the foregoing amendment after its adoption by the
stockholders of the Company will not adversely affect any right or protection
of a director of the Company existing at the time of such repeal or
modification.
 
  The Board of Directors and the Company's stockholders have approved the use
of an indemnification agreement (the "Indemnification Agreement"). The
Indemnification Agreement requires that the Company indemnify directors and
executive officers who are parties thereto in all cases to the fullest extent
permitted by applicable Delaware law. This contract right to indemnification
gives all directors and executive officers protection against a subsequent
adverse change in the Company's indemnification provisions in its By-laws on a
change of control of the Company.
 
  The Company has obtained an insurance policy insuring its officers and
directors for certain acts in connection with their services as such.
 
  Reference is made to the Underwriting Agreement, the proposed form of which
is filed as Exhibit 1, in which each underwriter agrees to indemnify the
directors and certain officers of the Registrant and certain other persons
against certain civil liabilities.

ITEM 17.  UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
Registrant described in Item 15 or otherwise, the Registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for the indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
 
    (3) For purposes of determining any liability under the Securities Act,
  each filing of the Registrant's annual report pursuant to Section 13(a) or
  Section 15(d) of the Exchange Act (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to Section 15(d) of the
  Exchange Act) that is incorporated by reference in the Registration
  Statement shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

                                       2


          1.  Registration Statement.  The Company has filed with the Securities
              ----------------------                                            
and Exchange Commission (herein called the "Commission") a registration
statement on Form S-3 (No. 33-_____), including the related preliminary
prospectus, for the registration under the Securities Act of 1933, as amended
(the "Securities Act"), of the Stock.  Copies of such registration statement and
of each amendment thereto, if any, including the related preliminary prospectus
(meeting the requirements of Rule 430A of the rules and regulations of the
Commission) heretofore filed by the Company with the Commission have been
delivered to you.

          The term "Registration Statement" as used in this Agreement shall mean
such registration statement, including all exhibits, financial statements and
documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the Securities Act and all information omitted therefrom in reliance on
Rule 430A and contained in the Prospectus referred to below, in the form in
which it became effective and, in the event of any amendment thereto after the
effective date of such registration statement (herein called the "Effective
Date"), shall also mean (from and after the effectiveness of such amendment)
such registration statement as so amended.  The term "Prospectus" as used in
this Agreement shall mean the prospectus, including the documents incorporated
by reference therein, relating to the Stock first filed with the Commission
pursuant to Rule 424(b) and Rule 430A or (if no such filing is required) as
included in the Registration Statement and, in the event of any supplement or
amendment to such prospectus after the Effective Date, shall also mean (from and
after the filing with the Commission of such supplement or of the effectiveness
of such amendment) such prospectus as so supplemented or amended.  The term
"Preliminary Prospectus" as used in this Agreement shall mean each preliminary
prospectus, including the documents incorporated by reference therein, included
in such registration statement prior to the time it becomes effective.

          The Registration Statement has been declared effective under the
Securities Act, and no post-effective amendment to the Registration Statement
has been filed as of the date of this Agreement.  The Company has caused to be
delivered to you copies of each Preliminary Prospectus and has consented to the
use of such copies for the purposes permitted by the Securities Act.

          2.  Representations and Warranties of the Company.  The Company 
              ---------------------------------------------
hereby represents and warrants as follows:

          (i) The Company meets the requirements for use of Form S-3 under the
     Securities Act.

          (ii) [Each][The] Preliminary Prospectus filed prior to the Effective
     Date bore the legends required by Item 501 of Regulation S-K of the
     Securities Act.
<PAGE>
 
                                       3

          (iii)  The Company has been duly incorporated and is validly existing
     as a corporation in good standing under the laws of the jurisdiction of its
     incorporation, has full corporate power and authority to own or lease its
     properties and conduct its business as described in the Registration
     Statement and the Prospectus and as being conducted, and is duly qualified
     as a foreign corporation and in good standing in all jurisdictions in which
     the character of the property owned or leased or the nature of the business
     transacted by it makes qualification necessary (except where the failure to
     be so qualified would not have a material adverse effect on the business,
     properties, financial condition or earnings of the Company and its
     subsidiaries, taken as a whole).

          (iv) Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, there has not been any
     material adverse change in the business affairs or business prospects,
     properties, financial condition or earnings of the Company and its
     subsidiaries as a whole, whether or not arising from transactions in the
     ordinary course of business, other than as set forth in the Registration
     Statement and the Prospectus, and since such dates, except in the ordinary
     course of business, neither the Company nor its subsidiaries have entered
     into any material transaction not referred to in the Registration Statement
     and the Prospectus.  Since such dates, no dividend or distribution of any
     kind has been declared or has been paid or made by the Company on its
     capital stock.

          (v) There are no outstanding options, warrants or other rights granted
     by the Company to purchase shares of its Common Stock or other securities,
     other than the Stock to be sold pursuant to this Agreement and as otherwise
     described in the Prospectus and, to the best of the knowledge of the
     Company, no such option, warrant or other right has been granted to any
     person, the exercise of which would cause such person to own more than 5
     percent of its Common Stock outstanding immediately after the offering of
     the Stock, other than as might result from the sale of the Stock pursuant
     to this Agreement and as otherwise described in the Prospectus.

          (vi) No further approval or authority of the stockholders or
     shareholders or the Board of Directors of the Company will be required for
     the issuance and sale of the Stock as contemplated herein.

          (vii)  The Commission has not issued any order preventing or
     suspending the use of any Preliminary Prospectus; the Registration
     Statement and the Prospectus comply and, on the Closing Date (as
     hereinafter defined) and any later date on which shares of Option Stock are
     to be purchased, the Prospectus will comply in all material respects with
     the provisions of the Securities Act and the Securities Exchange Act of
     1934, as amended (the "Exchange Act"), and the rules and regulations of the
     Commission thereunder; on the Effective Date, the Registration Statement
     did not contain any untrue statement of material fact and did not omit to
     state any material
<PAGE>
 
                                       4

     fact required to be stated therein or necessary in order to make the
     statements therein not misleading; and, on the date of its issuance, the
     Prospectus did not and, on the Closing Date and any later date on which
     shares of Option Stock are to be purchased, will not contain any untrue
     statement of a material fact or omit to state any material fact necessary
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; provided, however, that none of
                                                 --------  -------              
     the representations and warranties in this subparagraph (vii) shall apply
     to statements in, or omissions from, the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information
     furnished in writing to the Company by or on behalf of you expressly for
     use in the Registration Statement or the Prospectus.

          (viii)  The documents incorporated by reference in the Prospectus
     pursuant to Item 12 of Form S-3 under the Securities Act, at the time they
     were filed with the Commission, complied in all material respects with the
     requirements of the Exchange Act and the rules and regulations of the
     Commission thereunder and, when read together and with the other
     information in the Prospectus, at the time the Registration Statement
     became effective and at all times subsequent thereto up to the Closing Date
     (and, if any shares of Option Stock are purchased, up to the Date of
     Delivery), will not contain an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary in
     order to make the statements therein not misleading.

          (ix) The execution and delivery of this Agreement, the issuance, sale
     and delivery of the Stock, the consummation by the Company of the
     transactions contemplated in this Agreement and in the Registration
     Statement and compliance by the Company with the terms of this Agreement
     have been duly authorized by all necessary corporate action on the part of
     the Company and do not and will not conflict with, or result in a breach
     of, the respective Articles or Certificate of Incorporation or bylaws (or
     corporate documents of similar effect) of the Company or any of its
     subsidiaries, nor will the performance of this Agreement and the
     consummation of the transactions herein contemplated result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under, (a) any indenture, mortgage, deed of trust, loan agreement, bond,
     debenture, note agreement or other evidence of indebtedness, lease,
     contract or other agreement or instrument to which the Company or any of
     its subsidiaries is a party or by which the property of any of them is
     bound or (b) any statute or any order, rule or regulation of any court or
     governmental agency or body having jurisdiction over the Company or any of
     its subsidiaries or over the properties of any of them; and no consent,
     approval, authorization or order of any court or governmental agency or
     body is required for the consummation by the Company of the transactions
     herein and therein contemplated, except such as may be required under the
     Securities Act or under the
<PAGE>
 
                                       5

     securities or Blue Sky laws of the various states, or by the National
     Association of Securities Dealers, Inc. (herein called the "NASD").

          (x) The Company had at the date indicated a duly authorized and
     outstanding capitalization as set forth in the Prospectus under the caption
     "Capitalization", and the Common Stock conforms in all material respects to
     the description thereof contained or incorporated by reference in the
     Prospectus, and such description conforms in all material respects to the
     rights set forth in the instruments defining the same.

          (xi) All of the outstanding shares of capital stock of the Company
     have been duly authorized and validly issued and are fully paid and non-
     assessable; no holder thereof is or will be subject to personal liability
     solely by reason of being such a holder, and none of the outstanding shares
     of Common Stock was issued in violation of the preemptive rights of any
     stockholder of the Company.

          (xii)  The shares of Stock have been duly authorized and, when issued,
     sold and delivered against payment therefor as provided herein, such shares
     of Stock will be validly issued, fully paid and non assessable; no holder
     thereof will be subject to personal liability solely by reason of being
     such a holder; such shares of Stock will not be subject to the preemptive
     rights of any stockholder of the Company; and all corporate action required
     to be taken for the authorization, issuance and sale of the shares of Stock
     has been validly and sufficiently taken.

          (xiii)  The Company owns, or possesses adequate rights to use, all
     material patents, patent rights, inventions, trade secrets, licenses, know-
     how, proprietary techniques, including processes and substances,
     trademarks, service marks, trade names and copyrights described or referred
     to in the Prospectus, or owned or used by it or which are necessary for the
     conduct of its business as described in the Prospectus (herein collectively
     called the "Information Property").  Except as disclosed in the Prospectus,
     the Company has not received any notice of infringement of, or notice from
     the holder of any Information Property or from any person having a
     proprietary interest in any Information Property of a conflict with
     asserted rights of others with respect to, any Information Property which,
     singly or in the aggregate, if the subject of an unfavorable decision,
     ruling or finding, would materially adversely affect the business
     operations, financial condition, income or business prospects of the
     Company and its subsidiaries, taken as a whole.

          (xiv)  The Company holds all material licenses, certificates and
     permits from state, federal and other regulatory authorities which are
     necessary for the conduct of its business; the Company is not in violation
     of its Articles or Certificate of Incorporation or bylaws (or corporate
     documents of similar effect).  Neither the
<PAGE>
 
                                       6

     Company nor its subsidiaries are in default in the performance or
     observance of any provision of any obligation, agreement, covenant or
     condition contained in any bond, debenture, note or other evidence of
     indebtedness or in any contract, indenture, mortgage, loan agreement, joint
     venture or other agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which any of them or any of their respective
     properties may be bound, or are in violation of any law, order, rule,
     regulation, writ, injunction or decree of any government, governmental
     instrumentality or court, domestic or foreign, the violation of which, or
     default in the performance or observance of which, would have a material
     effect on the business affairs or business prospects, properties, financial
     condition or earnings of the Company and its subsidiaries, taken as a
     whole.

          (xv) Except as set forth in the Prospectus, there is no action, suit
     or proceeding, at law or in equity, pending or, to the best of the
     Company's knowledge, threatened against the Company or any of its
     subsidiaries by a private litigant, by any federal, state or other
     commission, board or agency or in any proceeding before any administrative
     agency, wherein any unfavorable result or decision could materially
     adversely affect the business affairs or business prospects, properties,
     financial condition or income or earnings of the Company or its
     subsidiaries, taken as a whole, or prevent consummation of the transactions
     contemplated hereby; and there are no contracts or documents of the Company
     which would be required to be filed as exhibits to the Registration
     Statement by the Securities Act and which have not been filed as exhibits
     to the Registration Statement.

          (xvi)  The consolidated financial statements of the Company and its
     subsidiaries, together with related notes and schedules as set forth in the
     Registration Statement or incorporated by reference therein, present fairly
     the financial position and the results of operations of the Company and its
     subsidiaries on a consolidated basis, at the indicated dates and for the
     indicated periods, in accordance with generally accepted accounting
     principles.  Such financial statements have been prepared in accordance
     with generally accepted accounting principles, consistently applied
     throughout the periods involved, and all adjustments necessary for a fair
     presentation of results for such periods have been made.  The summary
     financial data included in the Registration Statement present fairly the
     information shown therein and have been compiled on a basis consistent with
     the financial statements presented therein.

          (xvii)  The Company and each of its subsidiaries have fulfilled their
     obligations, if any, under the minimum funding standards of Section 302 of
     the United States Employee Retirement Income Security Act of 1974 (herein
     called "ERISA") and the regulations and published interpretations
     thereunder with respect to each "plan" (as defined in ERISA and such
     regulations and published interpretations)
<PAGE>
 
                                       7

     in which employees of the Company or any of its subsidiaries are eligible
     to participate, and each such plan is in compliance in all material
     respects with the presently applicable provisions of ERISA and such
     regulations and published interpretations, and have not incurred any unpaid
     liability to the Pension Benefit Guaranty Corporation (other than for the
     payment of premiums in the ordinary course) or to any such plan under Title
     IV of ERISA.

          (xviii)  No authorization, approval, consent or license of any
     government, governmental instrumentality or court, domestic or foreign
     (other than under the Securities Act, the securities or blue sky laws of
     the various states and the NASD), is required for the valid authorization,
     issuance and delivery of the Stock or the execution, delivery or
     performance of this Agreement by the Company.

          (xix)  Coopers & Lybrand, who have certified certain of the financial
     statements filed with the Commission as part of or incorporated by
     reference in the Registration Statement, are independent public accountants
     with respect to the Company as required by the Securities Act.

          (xx) Except as set forth in the Registration Statement and the
     Prospectus, each of the Company and its subsidiaries has filed all
     necessary United States income tax returns and all necessary state income,
     franchise, sales and use tax returns as required by law or regulation,
     domestic or foreign, and has paid all taxes shown thereon as due, and each
     of the Company and its subsidiaries has no knowledge of any tax deficiency
     which has been or might be asserted against any of them which would
     materially and adversely affect any of the businesses or properties of the
     Company and its subsidiaries taken as a whole; to the knowledge of the
     Company all tax liabilities are adequately provided for on the books of the
     Company and its subsidiaries.

          (xxi)  Neither the Company nor any subsidiary is involved in any labor
     dispute which, either individually or in the aggregate, could have a
     material adverse effect on the business or operations of the Company and
     its subsidiaries taken as a whole, nor, to the knowledge of the Company, is
     any such dispute threatened.

     bound, are in full force and effect.

                                       8

              ---------------------------------                            
agrees as follows:

          (a) The Company will (i) prepare and timely file with the Commission
     under Rule 424(b) a Prospectus containing information previously omitted at
     the time of effectiveness of the Registration Statement in reliance on Rule
     430A and (ii) not file any amendment to the Registration Statement or
     supplement to the Prospectus (including documents incorporated by reference
     in such Prospectus) of which you shall not have previously been advised and
     furnished with a copy or to which you shall have reasonably objected in
     writing or which is not in compliance with the Securities Act or the rules
     and regulations of the Commission.

          (b) The Company will promptly notify you in the event of (i) the
     request by the Commission for amendment of the Registration Statement or
     for supplement to the Prospectus or for any additional information, (ii)
     the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement, (iii) the institution or
     notice of intended institution of any action or proceeding for that
     purpose, (iv) the receipt by the Company of any notification with respect
     to the suspension of the qualification of the Stock for sale in any
     jurisdiction or (v) the receipt by it of notice of the initiation or
     threatening of any proceeding for such purpose.  The Company will make
     every reasonable effort to prevent the issuance of such a stop order and,
     if such an order shall at any time be issued, to obtain the withdrawal
     thereof at the earliest possible moment.
<PAGE>
 
                                       10

          (c) The Company will (i) on or before the Closing Date, deliver to you
     one signed copy of the Registration Statement as originally filed and of
     each amendment thereto filed prior to the time the Registration Statement
     became effective and, promptly upon the filing thereof, one signed copy of
     each post-effective amendment, if any, to the Registration Statement
     (together with, in each case, all exhibits thereto and documents filed
     therewith, including documents incorporated by reference into the
     Prospectus, unless previously furnished to you), and will also deliver to
     you a sufficient number of additional conformed copies of each of the
     foregoing (but without exhibits) as you may reasonably request, (ii) as
     promptly as possible deliver to you, at such office or offices as you may
     designate, as many copies of each Preliminary Prospectus and the Prospectus
     as you may reasonably request, and (iii) thereafter from time to time
     during the period in which a prospectus is required by law to be delivered
     by an Underwriter or dealer, likewise deliver to you as many additional
     copies of the Prospectus and as many copies of any supplement to the
     Prospectus and of any amended prospectus, filed by the Company with the
     Commission, as you may reasonably request for the purposes contemplated by
     the Securities Act.

          (d) If at any time during the period in which the Prospectus is
     required by law to be delivered by an Underwriter or dealer any event
     relating to or affecting the Company or any of its subsidiaries, or of
     which the Company shall be advised in writing by you, shall occur as a
     result of which it is necessary, in the opinion of counsel for the Company
     or your counsel, to supplement or amend the Prospectus in order to make the
     Prospectus not misleading in the light of the circumstances existing at the
     time it is delivered to a purchaser of the Stock, the Company will
     forthwith prepare and file with the Commission a supplement to the
     Prospectus or an amended Prospectus so that the Prospectus as so
     supplemented or amended will not contain any untrue statement of a material
     fact or omit to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances existing at the time
     such Prospectus is delivered to such purchaser, not misleading.  If, after
     the initial public offering of the Stock by you and during such period in
     which the Prospectus is required by law to be delivered by an Underwriter
     or dealer, you shall propose to vary the terms of the offering thereof by
     reason of changes in general market conditions or otherwise (provided,
                                                                  -------- 
     however, that the price to be paid to the Company for the Stock shall not
     -------                                                                  
     be varied), you will advise the Company in writing of the proposed
     variation, and, if in the opinion of either counsel for the Company or your
     counsel such proposed variation requires that the Prospectus be
     supplemented or amended, the Company will forthwith prepare and file with
     the Commission a supplement to the Prospectus or an amended Prospectus
     setting forth such variation.  The Company authorizes you and all dealers
     to whom any of the Stock may be sold by you to use the Prospectus, as from
     time to time amended or supplemented, in
<PAGE>
 
                                       11

     connection with the sale of the Stock in accordance with the applicable
     provisions of the Securities Act and the applicable rules and regulations
     thereunder for such period.

          (e) Prior to the filing thereof with the Commission, the Company will
     submit to you, for your information, a copy of any post-effective amendment
     to the Registration Statement and any supplement to the Prospectus or any
     amended prospectus proposed to be filed.

          (f) The Company will cooperate, when and as requested by you, in the
     qualification of the Stock for offer and sale under the securities or Blue
     Sky laws of such jurisdictions in the United States as you may reasonably
     request and, during the period in which the Prospectus is required by law
     to be delivered by an underwriter or dealer, in keeping such qualifications
     in good standing under said securities or Blue Sky laws; provided, however,
                                                              --------  ------- 
     that the Company shall not be obligated to file any general consent to
     service of process or to qualify as a foreign corporation in any
     jurisdiction in which it is not so qualified.  The Company will, from time
     to time, prepare and file such statements, reports, and other documents as
     are or may be required to continue such qualifications in effect for so
     long a period as you may reasonably request for distribution of the Stock.

          (g) The Company will use its best efforts to effect the "listing" of
     the shares of Stock on the National Association of Securities Dealers
     Automated Quotation National Market System (herein called "NASDAQ NMS").
     The Company will file with NASDAQ NMS all documents and notices required by
     NASDAQ NMS of companies that have issued securities that are traded in the
     over-the-counter market and quotations for which are reported by NASDAQ
     NMS.

          (h) During a period of five years commencing with the date hereof, the
     Company will furnish to you copies of all periodic and special reports
     furnished to stockholders of the Company and of all information, documents
     and reports filed with the Commission.

          (i) Not later than the 45th day following the end of the fiscal
     quarter first commencing after the first anniversary of the effective date
     of the Registration Statement, the Company will make generally available to
     its security holders an earnings statement of the Company in accordance
     with Section 11(a) of the Securities Act or shall otherwise comply in full
     with the provisions of Rule 158 of the Commission.

          (j) The Company agrees to pay all costs and expenses incident to the
     performance of its obligations under this Agreement, including all
     reasonable costs and expenses incident to (i) the preparation, printing and
     filing with the Commission
<PAGE>
 
                                       12

     and the NASD of the Registration Statement, any Preliminary Prospectus and
     the Prospectus, and any amendments or supplements thereto, (ii) the
     furnishing to you of copies of any Preliminary Prospectus and of the
     several documents required by paragraph (c) of this Section 6 to be so
     furnished, (iii) the reproduction of this Agreement and related documents
     delivered to you, (iv) the preparation, printing and filing of all
     supplements and amendments to the Prospectus referred to in paragraph (d)
     of this Section 6, (v) the furnishing to you of the reports and information
     referred to in paragraph (h) of this Section 6, and (vi) the printing and
     issuance of stock certificates, including the transfer agent's fees.

          (k) The Company agrees to reimburse you for Blue Sky fees and related
     disbursements (including counsel fees and disbursements and the cost of
     reproducing memoranda for you) paid by or for your account or your counsel
     in qualifying the Stock under state securities or Blue Sky laws and in the
     review of the offering by the NASD.

          (l) The Company agrees that, without the prior written consent of
     Hambrecht & Quist Incorporated ("Hambrecht & Quist"), the Company will not,
     directly or indirectly, sell, offer, contract to sell, make any short sale
     of, pledge, grant any option to purchase or otherwise dispose of any shares
     of Common Stock or any securities convertible into or exchangeable or
     exercisable for or any rights to purchase or acquire Common Stock for a
     period of 90 days following the commencement of the public offering of the
     Stock by you, other than (i) the Stock to be sold to you pursuant to this
     Agreement, (ii) to consultants and grantors of licensing rights and (iii)
     to directors, officers and employees in accordance with the Company's
     customary practices.

          (m) The Company is familiar with the Investment Company Act of 1940,
     as amended, and the rules and regulations thereunder (the "Investment
     Company Act"), and has in the past conducted its affairs, and will invest
     the proceeds of the transaction contemplated by this Agreement (the
     "Proceeds"), in such a manner as to ensure that the Company was not, and
     will not as a result of investment of the Proceeds be, an "investment
     company" or a company "controlled" by an "investment company" within the
     meaning of the Investment Company Act.

          (n) If the Company has elected to rely upon Rule 430A, it will take
     such steps as it deems necessary to ascertain promptly whether the form of
     prospectus transmitted for filing under Rule 424(b) was received for filing
     by the Commission and, in the event that it was not, it will promptly file
     such prospectus.

          7.  Indemnification and Contribution.  (a)  Subject to the provisions
              --------------------------------                                 
of paragraph (d) of this Section 7, the Company agrees to indemnify and hold
harmless each
<PAGE>
 
                                       13

Underwriter and each person (including each partner and officer thereof) who
controls such Underwriter within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims, damages or liabilities, joint or
several, to which such indemnified parties or any of them may become subject
under the Securities Act, the Exchange Act, the common law or otherwise, and the
Company agrees to reimburse each Underwriter and each such controlling person
for any legal or other expenses (including, except as otherwise hereinafter
provided, reasonable fees and disbursements of counsel) incurred by the
respective indemnified parties in connection with defending against any such
losses, claims, damages or liabilities or in connection with any investigation
of or inquiry into, or other proceeding which may be brought against, the
respective indemnified parties, in each case arising out of or based upon (i)
any untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement (including the Prospectus as part thereof and
documents incorporated by reference therein) or any post-effective amendment
thereto, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, or
(ii) any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus or the Prospectus (as amended or as
supplemented if the Company shall have filed with the Commission any amendment
thereof or supplement thereto, including documents incorporated by reference
therein), or the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
                                                          --------  ------- 
that (1) the indemnity agreements of the Company contained in this paragraph (a)
shall not apply to any such losses, claims, damages, liabilities or expenses if
such statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of the
Underwriters expressly for use in any Preliminary Prospectus or the Registration
Statement or the Prospectus or any such amendment thereof or supplement thereto
and (2) the indemnity agreement contained in this paragraph (a) with respect to
any Preliminary Prospectus shall not inure to the benefit of the Underwriters
from whom the person asserting any such losses, claims, damages, liabilities or
expenses purchased the Stock which is the subject thereof (or to the benefit of
any person controlling such Underwriter) if at or prior to the written
confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) (in each case exclusive of the documents
from which information is incorporated by reference) was not sent or delivered
to such person and the untrue statement or omission of a material fact contained
in such Preliminary Prospectus was corrected in the Prospectus (or the
Prospectus as amended or supplemented) unless the failure is the result of the
noncompliance by the Company with paragraph (c) of Section 6 hereof.  The
indemnity agreements of the Company contained in this paragraph (a) and the
representations and warranties of the Company contained in Section 2 hereof
shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any indemnified party and shall survive
the delivery of and payment for the Stock.
<PAGE>
 
                                       14

          (b) Subject to the provisions of paragraph (d) of this Section 7, you
agree to indemnify and hold harmless the Company, each of its officers who signs
the Registration Statement on his own behalf or pursuant to a power of attorney,
each of its directors and each person (including each partner or officer
thereof), if any, who controls the Company or the Underwriters within the
meaning of Section 15 of the Securities Act from and against any and all losses,
claims, damages or liabilities, joint or several, to which such indemnified
parties or any of them may become subject under the Securities Act, the Exchange
Act or the common law or otherwise and to reimburse each of them for any legal
or other expenses (including, except as otherwise hereinafter provided,
reasonable fees and disbursements of counsel) incurred by the respective
indemnified parties in connection with defending against any such losses,
claims, damages or liabilities or in connection with any investigation of or
inquiry into, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof) or any post-
effective amendment thereto, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading or (ii) any untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus or the
Prospectus (as amended or as supplemented if the Company shall have filed with
the Commission any amendment thereof or supplement thereto) or the omission or
alleged omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, if such statement or omission was made in reliance upon
and in conformity with information furnished in writing to the Company by or on
behalf of you expressly for use in any Preliminary Prospectus or the
Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto.  The indemnity agreements of the Underwriters contained in
this paragraph (b) shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any indemnified party
and shall survive the delivery of and payment for the Stock representing the
Preferred Shares.

          (c) Each party indemnified under the provisions of paragraph (a) or
(b) of this Section 7 agrees that, upon the service of a summons or other
initial legal process upon it in any action or suit instituted against it or
upon its receipt of written notification of the commencement of any
investigation of or inquiry into or proceeding against it, in respect of which
indemnity may be sought on account of any indemnity agreement contained in such
paragraphs, it will promptly give written notice (herein called the "Notice") of
such service or notification to the party or parties from whom indemnification
may be sought hereunder.  No indemnification provided for in such paragraph
shall be available to any party who shall fail so to give the Notice if the
party to whom such Notice was not given was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such
<PAGE>
 
                                       15

indemnifying party or parties from any liability which it or they may have to
the indemnified party for contribution or other than on account of such
indemnity agreement.  Any indemnifying party shall be entitled at its own
expense to participate in the defense of any action, suit or proceeding against,
or investigation of or inquiry into, an indemnified party.  Any indemnifying
party shall be entitled, if it so elects within a reasonable time after receipt
of the Notice, by giving written notice (herein called the "Notice of Defense")
to the indemnified party to assume (alone or in conjunction with any other
indemnifying party or parties) the entire defense of such action, suit,
investigation, inquiry or proceeding in which event such defense shall be
conducted, at the expense of the indemnifying party or parties, by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to the
indemnified party or parties; provided, however, that (i) if the indemnified
                              --------  -------                             
party or parties reasonably determine that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action, suit, investigation, inquiry
or proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or parties, then one counsel for the indemnified party or
parties chosen by the indemnified party or parties with the consent of the
indemnifying party, whose consent shall not be unreasonably withheld shall be
entitled to conduct the defense to the extent reasonably determined by such
counsel to be necessary to protect the interests of the indemnified party or
parties and (ii) in any event, the indemnified party or parties shall be
entitled to have counsel chosen by such indemnified party or parties participate
in, but not conduct, the defense.  If, within a reasonable time after receipt of
the Notice, an indemnifying party gives a Notice of Defense and the counsel
chosen by the indemnifying party or parties is reasonably satisfactory to the
indemnified party or parties, the indemnifying party or parties will not be
liable under paragraphs (a) through (c) of this Section 7 for any legal or other
expenses subsequently incurred by the indemnified party or parties in connection
with the defense of the action, suit, investigation, inquiry or proceeding
except that (A) the indemnifying party or parties shall bear the legal and other
expenses incurred in connection with the conduct of the defense as referred to
in clause (i) of the proviso to the preceding sentence and (B) the indemnifying
party or parties shall bear such other expenses as it or they have authorized to
be incurred by the indemnified party or parties.  If, within a reasonable time
after receipt of the Notice, no Notice of Defense has been given, the
indemnifying party or parties shall be responsible for any legal or other
expenses incurred by the indemnified party or parties in connection with the
defense of the action, suit, investigation, inquiry or proceeding.

          (d) If the indemnification provided for in this Section 7 is
unavailable or insufficient to hold harmless an indemnified party under
paragraph (a) or (b) of this Section 7, then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraph (a) or (b) of this Section 7 (i) in such
proportion as is appropriate to reflect the relative benefits received by each
<PAGE>
 
                                       16

indemnifying party from the offering of the Stock or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each indemnifying party in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, or actions in respect thereof, as well as any
other relevant equitable considerations.  The relative benefits received by the
Company and the Underwriters shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Stock received by
the Company and the total underwriting discounts received by the Underwriters,
as set forth in the table on the cover page of the Prospectus, bear to the
aggregate public offering price of the Stock.  Relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by each indemnifying party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such untrue statement or omission.

          The parties agree that it would not be just and equitable if
contributions pursuant to this Section 7(d) were to be determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the first sentence of this Section
7(d).  The amount paid by an indemnified party as a result of the losses,
claims, damages or liabilities referred to in the first sentence of this Section
7(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating, preparing to defend
or defending against any action or claim which is the subject of this Section
7(d).  Notwithstanding the provisions of this Section 7(d), the Underwriters
shall not be required to contribute any amount in excess of the underwriting
discounts and commissions applicable to the Stock purchased by the Underwriters.
No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          Each party entitled to contribution agrees that, upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it shall promptly give
written notice of such service to the party or parties from whom contribution
may be sought, but the omission so to notify such party or parties of any such
service shall not relieve the party from whom contribution may be sought of any
obligation it may have hereunder or otherwise (except as specifically provided
in Section 7(c) hereof).  No party will be liable for contribution with respect
to any action or claim settled without its written consent.

          (e) No party will, without the prior written consent of the other
party to this Agreement (herein called the other party), settle or compromise or
consent to the entry of any judgment in any pending or threatened claim, action,
suit or proceeding in respect of
<PAGE>
 
                                       17

which indemnification or any joinder may be sought hereunder (whether or not
such other party or any person who controls such other party within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party
to such claim, action, suit or proceeding) unless such settlement, compromise or
consent includes an unconditional release of such other party and each such
controlling person from all liability arising out of such claim, action, suit or
proceeding.

          8.  Termination.  This Agreement may be terminated by you at any time
              -----------                                                      
prior to the Closing Date by giving written notice to the Company if after the
date of this Agreement trading in the Common Stock shall have been suspended, or
if there shall have occurred (i) the engagement in hostilities or an escalation
of major hostilities by the United States or the declaration of war or a
national emergency by the United States on or after the date hereof, (ii) any
outbreak of hostilities or other national or international calamity or crisis or
change in economic or political conditions if the effect of such outbreak,
escalation, calamity, crisis or change in economic or political conditions in
the financial markets of the United States would, in the Underwriters'
reasonable judgment, make the offering or delivery of the Stock impracticable,
(iii) suspension of trading in securities generally or a material adverse
decline in value of securities generally on the New York Stock Exchange, the
American Stock Exchange, NASDAQ or the NASDAQ National Market System, or
limitation on prices (other than limitations on hours or numbers of days of
trading) for securities on any such exchange or system, (iv) the enactment,
publication, decree or other promulgation of any federal or state statute,
regulation, rule or order of, or commencement of any proceeding or investigation
by, any court, legislative body, agency or other governmental authority which in
the Underwriters' reasonable opinion materially and adversely affects or will
materially or adversely affect the business or operations of the Company, (v)
declaration of a banking moratorium by either federal or New York State
authorities or (vi) the taking of any action by any federal, state or local
government or agency in respect of its monetary or fiscal affairs which in the
Underwriters' reasonable opinion has a material adverse effect on the securities
markets in the United States.  If this Agreement shall be terminated pursuant to
this Section 8, there shall be no liability of the Underwriters to the Company
or of the Company to the Underwriters; provided, however, that in the event of
                                       --------  -------                      
any such termination the Company agrees to indemnify and hold harmless the
Underwriters from all costs or expenses incident to the performance of the
obligations of the Company under this Agreement, including all costs and
expenses referred to in paragraphs (j) and (k) of Section 6 hereof.

          9.  Conditions of Underwriters' Obligations.  The obligations of the
              ---------------------------------------                         
Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company of all of its respective obligations to be performed
hereunder at or prior to the Closing Date or at any later date on which shares
of Option Stock are to be purchased, as the case may be, and to the following
further conditions:

     statements made in the Registration Statement and the Prospectus (including
     the documents incorporated by reference) were true and correct and neither
     the Registration Statement nor the Prospectus omitted to state any material
     fact required to be stated therein or necessary in order to make the
     statements therein not misleading, (ii) since the Effective Date, no event
     has occurred which should have been set forth in a supplement or amendment
     to the Prospectus which has not been set forth in such a supplement or
     amendment, (iii) since the respective dates as of which information is
     given in the Registration Statement in the form in which it originally
     became effective and the Prospectus contained therein, there has not been
     any material adverse change in the business affairs or business prospects,
     properties, financial condition or earnings of the Company and its
     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, and since such dates, except in
<PAGE>
 
                                       19

     the ordinary course of business, neither the Company nor any of its
     subsidiaries has entered into any transaction material to the Company and
     its subsidiaries, taken as a whole, and not referred to in the Registration
     Statement in the form in which it originally became effective and the
     Prospectus contained therein, (iv) neither the Company nor any of its

     legal proceedings to which the Company or any of its subsidiaries is a

     subsidiaries, and which are not disclosed in the Registration Statement and
     the Prospectus, (vi) there are no franchises, contracts, leases or other
     documents which are required to be filed as exhibits to the Registration
     Statement which have not been filed as required, (vii) the representations
     and warranties of the Company herein are true and correct in all material
     respects as of the Closing Date or any later date on which shares of Option
     Stock are to be purchased, as the case may be, and (viii) there has not
     been any material change in the market for securities in general or in
     political, financial or economic conditions from those reasonably
     foreseeable as to render it impractical in your sole judgment to make a
     public offering of the Stock, or a material adverse change in market levels
     for securities in general (or those of companies in particular) or
     financial or economic conditions which render it inadvisable to proceed.

          (f) You shall have received on the Closing Date and on any later date
     on which shares of Option Stock are purchased a certificate, dated the
     Closing Date or such later date, as the case may be, and signed by the
     Chairman of the Board-Chief Executive Officer and by the Vice President-
     Chief Financial Officer and Treasurer of the Company stating that the
     respective signers of said certificates have carefully examined the
     Registration Statement in the form in which it originally became effective
     and the Prospectus contained therein and any supplements or amendments
     thereto, and that the statements included in clauses (i) through (vii) of
     paragraph (e) of this Section 9 are true and correct.

     respect to the Company within the meaning of the Securities Act and based
     upon the procedures described in their letter delivered to you concurrently
     with the execution of this Agreement (herein called the "Original Letter"),
     but carried out to a date not more than five business days prior to the
     Effective Date, the Closing Date or such later date, as the case may be, on
     which shares of Option Stock are purchased (i) confirming, to the extent
     true, that the statements and conclusions set forth in the Original Letter
     are accurate as of the
<PAGE>
 
                                       20

     Effective Date, the Closing Date or such later date, as the case may be, on
     which shares of Option Stock are purchased and (ii) setting forth any
     revisions and additions to the statements and conclusions set forth in the
     Original Letter which are necessary to reflect any changes in the facts
     described in the Original Letter since the date of the Original Letter or

     information.  The letters shall not disclose any change, or any development
     involving a prospective change, in or affecting the business or properties
     of the Company or any of its subsidiaries which, in your sole judgment,
     makes it impractical or inadvisable to proceed with the public offering of
     the Stock or the purchase of shares of Option Stock as contemplated by the
     Prospectus.

          (h) You shall have been furnished evidence in the usual written or

     warranties of the Company, the performance of their respective obligations
     hereunder, and as to other conditions concurrent with and precedent to the
     obligations of the Underwriters hereunder.

          (j) On or prior to the Closing Date, you shall have received from all
     of the officers listed on Schedule 1 hereto agreements stating that without
     the prior written consent of Hambrecht & Quist, each of such holders will
     not, directly or indirectly, sell, offer, contract to sell, make any short
     sale, pledge or otherwise dispose of any shares of Common Stock or any
     securities convertible into or exchangeable or exercisable for or any
     rights to purchase or acquire Common Stock for a period of 90 days
     following the commencement of the public offering of the Stock by the
     Underwriters.

          All of the agreements, opinions, certificates and letters mentioned
above or elsewhere in this Agreement shall be deemed to be in compliance with
the provisions hereof only if Shearman & Sterling, counsel for the Underwriters,
shall be reasonably satisfied that they comply in form and scope.

          In case any of the conditions specified in this Section 9 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company.  Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
                                                                       -------- 
however, that (i) in the event of any such termination, the Company agrees to
- -------                                                                      
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under
<PAGE>
 
                                       21

this Agreement, including all costs and expenses referred to in paragraphs (j)
and (k) of Section 6 hereof, and (ii) if this Agreement is terminated by you
because of any refusal, inability or failure on the part of the Company to
perform any agreement herein, to fulfill any of the conditions herein or to
comply with any provision hereof other than by reason of a default by the
Underwriters, the Company will reimburse the Underwriters upon demand for all
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by it in connection with the transactions
contemplated hereby.

          10.  Conditions to the Obligations of the Company.  The obligation of
               --------------------------------------------                    
the Company to deliver the Stock shall be subject to the conditions that (a) the
Registration Statement shall have become effective and (b) no stop order
suspending the effectiveness of the Registration Statement shall be in effect
and no proceedings therefor shall be pending or threatened by the Commission at
the Closing Date.

          In case either of the conditions specified in this Section 10 shall
not be fulfilled, this Agreement may be terminated by the Company by giving
notice to you.  Any such termination shall be without liability of the Company
to the Underwriters and without liability of the Underwriters to the Company;
                                                                             
provided, however, that in the event of any such termination the Company agrees
- --------  -------                                                              
to indemnify and hold harmless the Underwriters from all costs or expenses
incident to the performance of the obligations of the Company under this
Agreement, including all costs and expenses referred to in paragraphs (j) and
(k) of Section 6 hereof.

          11.  Reimbursement of Certain Expenses.  In connection with its
               ---------------------------------                         
obligations under Section 7 of this Agreement, the Company hereby agrees to
reimburse the Underwriters on a quarterly basis for all reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described in
paragraph (a) of Section 7 of this Agreement, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the obligations
under this Section 11 and the possibility that such payments might later be held
to be improper; provided, however, that (i) to the extent any such payment is
                --------  -------

the provisions of Section 7 hereof, the several parties (in addition to the
Company and the Underwriters) indemnified under the provisions of said Section
7, and their respective personal representatives, successors and assigns.

                        RE:  THE LIPOSOME COMPANY, INC.
                             --------------------------


Ladies and Gentlemen:

         We have acted as counsel to The Liposome Company, Inc. (the "Company")
in connection with the issuance by the Company of 3,000,000 shares of the
Company's common stock, $.01 par value (the "Common Stock"), pursuant to the
Underwriting Agreement dated _______, 1995 (the "Underwriting Agreement") among
the Company and Hambrecht & Quist Incorporated and UBS Securities Inc. (the
"Underwriters").

         We have also acted as counsel to the Company in connection with the
preparation of the Company's Registration Statement on Form S-3, Registration
No. 33-_____, filed with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (collectively, the "Securities Act").  All
terms, unless otherwise defined herein, have the meanings assigned to them in
the Underwriting Agreement.

         In arriving at the opinions expressed below, we have examined and
relied upon, among other things, such certificates of public officials and
responsible officers of the Company and such originals or copies, certified or
otherwise identified to our satisfaction, of corporate documents and records of
the Company and its subsidiaries, as we have deemed necessary or appropriate for
the purposes hereof.  In giving this opinion, we assume that the certificates
representing the Common Stock conform to the specimens examined by us, that the
Stock has been completed as to the numbers of shares and names of registered
stockholders pursuant to Section 5 of the Underwriting Agreement and have been
countersigned and registered by Midlantic Bank as
<PAGE>
 
                                       2

Registrar.  In giving this opinion, we are also assuming the authenticity of all
instruments presented to us as originals, the conformity to the originals of all
instruments presented to us as copies, the genuineness of all signatures and the
competency of all individuals signing all instruments presented to us.

         On the basis of the foregoing, we are of the opinion that:

          (i) The Company is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Delaware, with corporate
     power and authority under such laws to own its properties and conduct its
     business as described in the Prospectus.

          (ii) The Company is duly qualified to transact business as a foreign
     corporation and is in good standing in each jurisdiction in which it owns
     or leases property of a nature, or transacts business of a type, that would
     make such qualification necessary, except to the extent that the failure to
     so qualify or be in good standing would not have a material adverse effect
     on the Company and its subsidiaries taken as a whole.

          (iii)  The shares of Stock have been duly authorized, and, when
     issued, sold and delivered against payment therefor in accordance with the
     terms of the Underwriting Agreement, such shares of Stock will be validly
     issued by the Company, fully paid and non assessable, and no holder thereof
     will be subject to personal liability solely by reason of being such a
     holder; to the best of our knowledge, such shares of Stock will not be
     subject to the preemptive rights of any stockholder of the Company; and all
     corporate action required to be taken for the authorization, issuance and
     sale of such shares of the Stock has been validly and sufficiently taken.

          (iv) The Common Stock conforms in all material respects as to legal
     matters to the description thereof contained in the Prospectus under the
     heading of "Description of Capital Stock".
                 ----------------------------  

          (v) All of the outstanding shares of capital stock of the Company
     prior to the issuance of the Stock have been duly authorized and validly
     issued and are fully paid and non assessable; no holder thereof is or will
     be subject to personal liability solely by reason of being such a holder;
     and, to our knowledge, none of such outstanding shares of capital stock of
     the Company was issued in violation of the preemptive rights of any holder
     of any securities of the Company.

          (vi) The number of shares of authorized, issued and outstanding
     capital stock of the Company is as set forth in the Prospectus under the
     heading "Capitalization".  We express no opinion as to financial
              --------------                                         
     information set forth under such heading.
<PAGE>
 
                                       3

          (vii)  No approval, consent, order, authorization, designation,
     declaration of or filing by or with any regulatory, administrative or other
     governmental body is necessary in connection with the execution and
     delivery by the Company of the Underwriting Agreement and the consummation
     of the transactions therein contemplated (except such of the aforementioned
     as have been obtained under the Securities Act and such as may be required
     by the National Association of Securities Dealers, Inc. or as may be
     necessary to qualify the Stock for public offering by the Underwriters
     under state securities or Blue Sky laws).

          (viii)  The execution and delivery by the Company of the Underwriting
     Agreement, the issuance and delivery of the Common Shares by the Company,
     the consummation by the Company of the transactions contemplated in the
     Underwriting Agreement and in the Registration Statement and the compliance
     by the Company with the terms of the Underwriting Agreement do not and will
     not conflict with any provision of the charter or bylaws of the Company or
     any of its subsidiaries and do not and will not conflict with, or result in
     a breach of any of the terms or provisions of, or constitute a default
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon any of the properties or assets of the Company or any of
     its subsidiaries under, (a) any indenture, mortgage or loan agreement, or
     any other agreement or instrument of which we have knowledge, to which the
     Company or any of its subsidiaries is a party or by which any of them may
     be bound or to which any of the properties of any of them may be subject
     (except for such conflicts, breaches or defaults or liens, charges or
     encumbrances that would not have a material adverse effect on the condition
     (financial or otherwise), earnings, business affairs or business prospects
     of the Company and its subsidiaries considered as one enterprise), (b) any
     existing applicable law, rule or regulation (other than the securities or
     Blue Sky laws of the various states, as to which we express no opinion) or
     (c) any judgment, order or decree, of which we have knowledge, of any
     government, governmental instrumentality or court, domestic or foreign,
     having jurisdiction over the Company, any of its subsidiaries or any of
     their properties.

          (ix) The Registration Statement has been declared effective by the
     Commission under the Securities Act and we have no knowledge of any stop
     order or that the effectiveness of the Registration Statement has been
     suspended or withdrawn in any manner; any required filing of the Prospectus
     or any supplement thereto pursuant to Rule 424(b) has been made in the
     manner and within the time period required by Rule 424(b).

          (x) The Registration Statement and the Prospectus, and each amendment
     or supplement thereto including documents incorporated by reference therein
     (except for the financial statements and other financial or statistical
     data included therein or omitted therefrom, as to which we express no
     opinion), as of their respective effective or issue dates, appear on their
     face to have been appropriately responsive in all material respects to the
     requirements of the Securities Act.
<PAGE>
 
                                       4

          (xi) The documents incorporated by reference in the Prospectus (except
     for the financial statements and other financial or statistical data
     included therein or omitted therefrom, as to which we express no opinion),
     as of the dates they were filed with the Commission, appear  on their face
     to have been appropriately responsive in all material respects to the
     requirements of the Exchange Act and the rules and regulations thereunder.

          (xii)  Except as set forth in the Prospectus, we do not know of any
     action, suit or proceeding, at law or in equity, against the Company or its
     subsidiaries pending or threatened by a private litigant, by any federal,
     state or other commission, board or agency or any proceeding before any
     administrative agency wherein any unfavorable result or decision could
     materially adversely affect the business, property, financial condition,
     income or earnings of the Company and its subsidiaries, taken as a whole,
     or prevent consummation of the transactions contemplated in the
     Underwriting Agreement; and there are no contracts or documents, of which
     we have knowledge, of the Company or of its subsidiaries which would be
     required to be filed as exhibits to the Registration Statement by the
     Securities Act or by the rules and regulations thereunder which have not
     been filed as exhibits to the Registration Statement.

          (xiii)  To our knowledge, no stop order suspending the effectiveness
     of such Registration Statement has been issued and no proceedings for that
     purpose have been instituted or are pending or are contemplated under the
     Securities Act.

          We have acted as counsel to the Company in connection with the
preparation of the Registration Statement and in the course of such
representation have reviewed and discussed the information in the Registration
Statement and the Prospectus with officers and employees of the Company and with
the auditors and you and your counsel.  Although we have not independently
checked or verified any statements made in connection with such discussions and
review, except as expressly specified herein, and although we assume no
responsibility for the accuracy, completeness or fairness of the information set
forth in the Registration Statement and Prospectus (except as otherwise stated
in this letter), based upon our participation, we have no reason to believe (a)
that the Registration Statement (except for the financial  statements and other
financial or statistical data included therein or omitted therefrom, as to which
we express no opinion), at the time such Registration Statement became
effective, contained an untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (b) that the Prospectus, including the
documents incorporated by reference therein (except for the financial statements
and other financial or statistical data included therein or omitted therefrom,
as to which we express no opinion), at the time the Prospectus was issued or at
the date hereof, included or includes an untrue statement of a material fact or
omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                                       5

          In rendering the foregoing opinion, we express no opinion as to laws
other than the laws of the state of New York, the general corporate laws of the
State of Delaware and the federal law of the United States of America (exclusive
of patent law).

          This letter is furnished solely for the information of the
Underwriters in connection with the offering and sale of the Stock and may not
be relied upon by any other person.

Re: The Liposome Company, Inc.

    ____________ shares of Common Stock

Ladies and Gentlemen:

         I represent The Liposome Company, Inc. (the "Company") with respect to
matters of patent and licensing law.  At the request of the Company I provide to
you the following opinions.  All terms, unless otherwise defined herein, have
the meanings assigned to them in the Underwriting Agreement.

         I have studied and agree with the statements in the Prospectus dated
_______, 1995 of the Company under the captions "Risk Factors - Patents and
Proprietary Technology" and "Business - Patents and Proprietary Technology".

         Except as disclosed in the sections of the Prospectus mentioned above I
do not know of any pending or threatened legal or governmental proceeding
relating to patents or proprietary know-how owned or used by the Company or
others, to which the Company or any of its subsidiaries is a party or might be a
party or to which any of the properties of the Company or any of its
subsidiaries are subject or might be subject which, if adversely decided, would
have a material effect on the business operations, financial condition, income
or business prospects of the Company or any of its subsidiaries.

         Further, except as disclosed in the sections of the Prospectus
mentioned above, I have no knowledge of any infringement or alleged infringement
by the Company or any of its
<PAGE>
 
                                       2

subsidiaries of patent rights of any holder or of any person having a
proprietary interest in such patent rights, which could have a material adverse
effect on the business affairs or business prospects, properties, financial
condition or earnings of the Company or any of its subsidiaries.

         To my knowledge, the Company owns or possesses material licenses or
other rights to use all patents, trade secrets, trademarks, service marks or
other proprietary information or materials necessary to conduct the business now
being or proposed to be conducted by the Company as described in the Prospectus,
including the documents incorporated by reference therein.

         To my knowledge, no default exists in the performance or observance of
any material provision of any obligation, agreement, covenant or condition
contained in any bond, debenture, note or other evidence of indebtedness or in
any contract, indenture, mortgage, loan agreement, joint venture or other
agreement or instrument that is described or referred to in the Registration
Statement or the Prospectus including the documents incorporated by reference
therein or that is filed as an exhibit to the Registration Statement.

Ladies and Gentlemen:

         This is to confirm our understanding in connection with Section 11 of
the Underwriting Agreement dated of even date herewith between you and the
undersigned (the "Underwriting Agreement"), that, in addition to the obligations
set forth therein and:

         In addition to its other obligations under Section 7 of the
    Underwriting Agreement, the Underwriters hereby agree to reimburse the
    Company, on a quarterly basis, for all reasonable legal and other expenses
    incurred in connection with investigating or defending any claim, action,
    investigation, inquiry or other proceeding arising out of or based upon any
    statement or omission, or any alleged statement or omission described in
    paragraph (b) of Section 7 of the Underwriting Agreement as applicable to
    the Underwriters, notwithstanding the absence of a judicial determination as
    to the propriety and enforceability of the obligations under this Section 11
    and the possibility that such payments might later be held to be improper;
                                                                              
    provided, however, that (i) to the extent any such payment is ultimately

    refund them and (ii) such persons shall provide to the Underwriters, as
    applicable, upon request, reasonable assurances of their ability to effect
    any refund, when and if due.

Ladies and Gentlemen:
 
  We have acted as counsel to The Liposome Company, Inc., a Delaware

Registration Statement on Form S-3 on the date hereof (the "Registration
Statement") relating to the public offering of up to 3,450,000 shares (the

  Based on the foregoing, it is our opinion that:
 
    1. The issuance of the Stock has been lawfully and duly authorized; and

  fully paid and nonassessable.
 
  We consent to the filing of this opinion as Exhibit 5 to the Registration
Statement and to the references to this firm on the cover of the Registration
Statement and under the heading "Legal Matters" in the Prospectus included in
such Registration Statement.
 
                                          Very truly yours,
