                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                               September 30, 1996
                                   (unaudited)


1.       BASIS OF PRESENTATION

                            SEQUUS Pharmaceuticals, Inc. ("SEQUUS" or the
         "Company") is engaged in the development, manufacture, marketing and
         sale of proprietary liposome and lipid-based products primarily to
         treat cancer and certain fungal infections. The Company's strategic
         emphasis is on injectable pharmaceutical products designed to improve
         the efficacy and reduce the toxicity of selected existing and new drugs
         used to treat cancer and infectious diseases.

         In the opinion of management, the accompanying unaudited condensed
         financial statements of SEQUUS contain all adjustments (consisting of
         only normal recurring adjustments) necessary to present fairly the
         financial position as of September 30,1996, and the results of
         operations for the three and nine month periods ended September 30,
         1996 and 1995, and the changes in cash flows for the nine month periods
         ended September 30, 1996 and 1995, in accordance with generally
         accepted accounting principles.

         These condensed financial statements should be read in conjunction with
         the Company's audited financial statements for the year ended December
         31, 1995, which were filed with the Securities and Exchange Commission
         on Form 10-K.

         Although the nature of the business is not seasonal, the results of
         operations for the interim periods presented are not necessarily
         indicative of the results to be expected for the full year.


2.       CASH AND CASH EQUIVALENTS AND MARKETABLE INVESTMENTS

         The Company invests its excess cash principally in government
         securities and high-grade investment paper. The Company maintains its
         cash, cash equivalents and investments in several different instruments
         with various banks and brokerage houses. The diversification of risk is
         consistent with Company policy to maintain liquidity and ensure the
         safety of principal.

         Management determines the appropriate classification of debt securities
         at the time of purchase and reevaluates such designation as of each
         balance sheet date. At September 30, 1996, all investments are
         classified as available-for-sale securities and are carried at fair
         value, with the unrealized gains and losses reported as a component of
         accumulated deficit. The amortized cost of debt securities in this
         category is adjusted for amortization of premiums and accretion of
         discounts to maturity. Such amortization is included in net interest
         and other income. Realized gains and losses and declines in value
         judged to be other than temporary on available-for-sale securities are
         included in net interest and other income. The cost of securities sold
         is based on the specific identification method.

4.       STOCKHOLDERS' EQUITY

         During the first nine months of 1996, the Company received
         approximately $8,958,000 from the exercise of warrants and stock
         options. Of this, approximately $3,000,000 was due to the exercise of
         warrants to purchase 705,714 shares of Common Stock at $4.25 per share
         and approximately $2,033,000 was due to the exercise of warrants to
         purchase 273,465 shares of Common Stock at $7.4328 a share. The
         warrants were acquired by investors in private placement financings in
         March 1991 and May 1995, respectively. Warrants for 500,000 shares of
         SEQUUS Common Stock, expiring in March 1997, remain outstanding from
         the March 1991 private placement and warrants for 838,380 shares,
         expiring in May 1999, remain outstanding from the May 1995 private
         placement. In addition, warrants for 808,320 shares of Common Stock at
         $7.425 per share, which expire in April 1998, remain outstanding from a
         private placement financing in March and April 1995.

         In February 1996, the Company gave notice to investors participating in
         a March 1995 private placement of the conversion to Common Stock of
         480,000 shares of Series A Convertible Reset Preferred Stock
         ("Preferred Stock"). Each share of Preferred Stock was converted into
         3.367 shares of Common Stock (rounded down to the nearest whole share).

ITEM 2.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The statements in this report that relate to future plans, events or performance
are forward-looking statements. Actual results, events or performance may differ
materially due to a variety of factors, including the factors described under
"Factors That May Affect Future Results, Events or Performance" below. Readers
are cautioned not to place undue reliance on these forward-looking statements,
which speak only as of the date hereof. The Company undertakes no obligation to
publicly release the result of any revisions to these forward-looking statements
that may be made to reflect events or circumstances after the date hereof or to
reflect the occurrence of unanticipated events.

OVERVIEW

    The Company is a leader in the development, manufacture, marketing and sale
of liposome and lipid-based biopharmaceutical products primarily to treat cancer
and certain infectious diseases. In November 1995, SEQUUS received marketing
clearance from the FDA for its proprietary anticancer drug, DOXIL(R)
(doxorubicin HCI liposome injection), for the treatment of Kaposi's sarcoma
("KS") in AIDS patients whose KS has progressed on prior chemotherapy or in
patients who are intolerant to such therapy. In December 1995, the Company
launched DOXIL in the U.S. In June 1996, the Company was granted marketing
authorization for DOXIL under the tradename CAELYX(TM), in the 15 member states
of the European Union ("EU"), for both first-line and second-line treatment of
AIDS-KS in patients with low CD4 counts and extensive mucocutaneous or visceral
disease. The drug may be used as first-line systemic chemotherapy, or as
second-line chemotherapy, in AIDS-KS patients with disease that has progressed
with, or in patients who are intolerant to, prior combination chemotherapy
comprising at least two of the following agents: a Vinca alkaloid, bleomycin,
and doxorubicin (or other anthracycline). A competitor of the Company has
received approval from the FDA for the use of a liposome anthracycline
formulation as first-line therapy for AIDS-KS and has also received approval for
the same indication in a number of additional countries. These approvals could
have an adverse effect on the market penetration of DOXIL.

     In September 1996, SEQUUS announced a distribution agreement with
Schering-Plough Corporation ("Schering-Plough") and, in partial consideration
for distribution rights, received from Schering-Plough a one-time upfront fee of
$5.3 million which was recorded in the quarter ended September 30, 1996. Under
the multi-year agreement, Schering-Plough will distribute, market and sell
CAELYX worldwide, except for the United States, Japan and certain small markets
subject to prior distribution arrangements. Under the terms of the agreement,
SEQUUS will receive payments for product sales to Schering-Plough. In addition,
Schering-Plough will fund a portion of the clinical development program for
CAELYX, conduct clinical trials for a solid tumor indication, apply for
regulatory approval in the Schering-Plough territories for all new indications,
and assist with pharmacoeconomic studies. The agreement also calls for potential
additional payments to the Company totaling $27 million based on the achievement
of certain product development milestones and events.

    AMPHOTEC(TM) (amphotericin B cholesteryl sulfate complex for injection), the
Company's proprietary product for treatment of life-threatening systemic fungal
infections, is being marketed in 16 countries and has been cleared for marketing
in an additional country. AMPHOTEC is indicated for the treatment of severe
and/or deep systemic mycoses in cases where toxicity or renal failure precludes
the use of conventional amphotericin B and in cases where prior systemic
antifungal therapy has failed. (AMPHOTEC is marketed under the tradename
AMPHOCIL in most countries outside of the U.S. and is also known as ABCD.)

     The Company has received marketing authorization approval for AMPHOTEC in
Argentina, Austria, Brazil, Denmark, the Czech Republic, Finland, Iceland,
Ireland, Italy, the Netherlands, Russia, Singapore, Slovenia, the Slovak
Republic, Sweden, Turkey and the U.K. Marketing Authorization Applications

("MAAs") for AMPHOTEC, submitted by the Company and Zeneca Pharmaceuticals
("Zeneca") are under assessment in a number of countries, including other
European countries, except in Norway where the MAA has been withdrawn. On
September 13, 1995, the CPMP reviewed the Company's multi-state application for
product marketing approval. Germany, France, Spain, Greece and Luxembourg did
not accept the MAA. SEQUUS believes national approval will be forthcoming in
Portugal. However, there can be no assurance that approvals, including pricing
approvals, will be forthcoming on a timely basis, or at all. In addition, after
the CPMP meeting, following further consideration by the Commission of Medicines
in Belgium, the Company has accepted an option for marketing authorization for
AMPHOTEC in a limited indication. A competitor of the Company has regulatory
approval in over 20 countries, primarily in Europe, to sell a liposome-based
amphotericin B product which targets indications similar to those targeted by
AMPHOTEC. Another competitor introduced its lipid-based amphotericin B product
as the third entrant in the U.K. market at a price substantially below the price
of the other lipid-based antifungals and recently launched the product as the
first lipid-based antifungal agent in the U.S. Competition from these two
competitors could have an adverse effect on the market penetration and pricing
of AMPHOTEC in both Europe and, if AMPHOTEC marketing clearance is obtained, in
the U.S.

    In August 1993, the Company signed a distribution agreement with Zeneca
under which Zeneca was to market and sell AMPHOTEC in most European countries.
In March 1994, SEQUUS and Zeneca announced the expansion of their August 1993
agreement to cover all countries not previously covered with the exception of
the United States, Canada, Japan and selected small markets. Sales of AMPHOTEC
to date have been below expectations. In July 1996, SEQUUS announced that it had
reacquired from Zeneca all international marketing and distribution rights for
AMPHOTEC except for nine European countries to which Zeneca had retained such
rights (Denmark, Finland, Holland, Iceland, Ireland, Italy, Portugal, Sweden and
the U.K.). In exchange for the return to SEQUUS of marketing and distribution
rights throughout the rest of the world, SEQUUS agreed to restructure certain
future milestone payments specified in the original 1993 agreement, adjust the
pricing terms for AMPHOTEC to provide greater competitive flexibility, and
exchange certain inventory.

    In August 1996 the Company announced the signing of an exclusive agreement
with Prodesfarma, S.A. for the marketing and distribution of AMPHOTEC in Spain,
Belgium and Luxembourg. The Company also announced the signing of an exclusive
agreement with TORREX Pharma Ges. M. b. H. of Vienna, Austria for the marketing
and distribution of AMPHOTEC in Austria, the Czech Republic, Hungary, Poland and
Slovenia.

    The Company will continue to evaluate various product distribution
arrangements for both AMPHOTEC and DOXIL which could affect near-term and
long-term financial performance.

    The Company has incurred losses in each year since its inception and had
accumulated approximately $145.0 million in net losses through September 30,
1996, including a loss of approximately $11.6 million in the first nine months
of 1996. Although the Company or its distributors have commenced marketing DOXIL
in the U.S. and certain international markets and AMPHOTEC in the U.K. and 15
other countries, the Company expects operating losses to continue in the near
term due to expenditures associated with research, preclinical testing and
clinical trials, marketing expenses and other expenses relating to the
development, manufacture, marketing and sale of its products. If the Company
expands clinical trials for additional indications of DOXIL or begins clinical
trials or expands preclinical studies for other products in the pipeline,
research and development spending may increase in future periods.

    The Company expects its marketing and sales expenses to increase
significantly as it proceeds with the commercialization of DOXIL and prepares
for the potential U.S. launch of AMPHOTEC (which is currently pending review by
the FDA) through its direct sales and marketing organization. As of September
30, 1996, SEQUUS had a sales force of 32 individuals experienced in the sale of
pharmaceutical and biopharmaceutical products, with particular emphasis on
oncology and infectious disease. The Company currently uses Ben Venue
Laboratories, Inc. ("Ben Venue"), a contract manufacturer, for the
commercial-scale manufacturing of its products.

RESULTS OF OPERATIONS

Three Months Ended September 30, 1996 and 1995

Revenues

    Total revenues were $11.6 million during the three month period ended
September 30, 1996 compared with $0.1 million recorded during the three month
period ended September 30, 1995. For the third quarter of 1996, product sales
were $6.2 million and, in addition, the Company received approximately $5.3
million in royalties and fees which included a small royalty payment from a
technology sublicensee and a one-time upfront fee of $5.3 million from Schering
Plough in partial consideration for distribution rights granted under the
distribution agreement. DOXIL sales represent 93.6% of total product sales in
the three month period ended September 30, 1996 compared to less than 1% in the
same period of 1995. For the three month period ended September 30, 1995, most
of the Company's product sales were sales of AMPHOTEC to agents, who marketed
the product to the customer. Modest shipments of AMPHOTEC were made to Zeneca in
the third quarter of 1996, and the Company anticipates only limited sales to
Zeneca for the foreseeable future.

Operating Expenses

    The Company's gross margin decreased to 83.2% of net sales in the three
month period ended September 30, 1996 from 87.9% of net sales in the three month
period ended September 30, 1995. The decrease in gross margin was due to higher
production costs. The Company anticipates that the gross margin on net product
sales will continue to fluctuate unless product volume increases.

      A substantial part of the Company's operating expenses are incurred for
research and development ("R&D"), including preclinical testing and clinical
trials required for new pharmaceutical products. The principal items of R&D
expense are personnel costs, costs for clinical trials, and costs associated
with production of clinical product and supplies. R&D increased to $7.6 million
in the three month period ended September 30, 1996, from $5.2 million in the
third quarter of 1995, an increase of $2.4 million. The increase in the third
quarter reflects increased spending on pipeline products, primarily SPI-77, a
STEALTH(R) liposome formulation of cisplatin, an anticancer drug. If the Company
expands clinical trials for additional indications of DOXIL or enters clinical
trials or expands preclinical studies with other products in the pipeline, R&D
expenses may continue to increase.

    Selling, general and administrative ("SG&A") expenses increased $0.8 million
to $3.9 million in the three month period ended September 30, 1996 from $3.1
million in the same period in 1995, principally reflecting an increase in
marketing and sales expenses related to the expansion of the sales force to
market DOXIL and to prepare for the potential launch of AMPHOTEC in the U.S. The
Company currently has a sales force of 32 individuals experienced in the sale of
pharmaceutical and biopharmaceutical products and additional internal staff to
support sales operations. The Company expects SG&A expenses to continue to
increase in preparation for the potential U.S. launch of AMPHOTEC.

Net Interest and Other Income

    Net interest and other income increased to approximately $0.4 million in the
three month period ended September 30, 1996 from approximately $0.3 million in
the same period of 1995, an increase of approximately $0.1 million principally
due to the increase in cash available for investment from the proceeds of the
Company's public offering of Common Stock in the fourth quarter of 1995 and the
exercise of warrants and stock options during the first nine months of 1996.


                                       8
<PAGE>   11
Net Loss

    The Company's net loss decreased to $0.7 million for the three month period
ended September 30, 1996 from a net loss of $8.0 million for the same period of
1995, a decrease of $7.3 million. The net loss per share was $0.02 for the three
month period ended September 30, 1996 compared to a $0.37 net loss per share in
the same period of 1995. The number of weighted shares outstanding at September
30, 1996 was 29,280,000 as compared to 21,545,000 at September 30, 1995. The
decrease in the net loss was due to the increase in net sales of DOXIL and the
one-time upfront fee of $5.3 million from the distribution agreement with
Schering-Plough, partially offset by an increase in total operating expenses.

Nine  Months Ended September 30, 1996 and 1995

Revenues

    Total revenues were $21.6 million during the nine month period ended
September 30, 1996 compared with $1.2 million recorded during the nine month
period ended September 30, 1995. Sales of DOXIL represent 94.2% of total product
sales in the nine month period ended September 30, 1996 compared to less than 1%
in the same period of 1995. For the nine month period ended September 30, 1995,
most of the Company's product sales represent sales of AMPHOTEC to Zeneca.
Modest shipments of AMPHOTEC were made to Zeneca in the first nine months of
1996.

Operating Expenses

    The Company's gross margin increased to 86.0% of net sales in the nine month
period ended September 30 1996 from 74.0% of net sales in the nine month period
ended September 30, 1995. The increase in gross margin was due to higher margins
associated with DOXIL sales in the U.S. where the Company currently markets
directly to the customer.

    R&D increased to $19.3 million in the nine month period ended September 30,
1996, from $15.9 million in 1995, an increase of $3.4 million. This increase is
due to an increase in spending on the product pipeline and general overall
increase in expense levels.

     SG&A expenses increased $3.5 million to $12.8 million in the nine month
period ended September 30, 1996 from $9.3 million in the same period in 1995,
principally reflecting an increase in marketing and sales expenses related to
the expansion of the sales force to market DOXIL and to prepare for the
potential launch of AMPHOTEC in the U.S. SG&A expenses in the nine month period
ended September 30, 1995 included accrued expenses in connection with
termination of the employment of certain officers.

Net Interest and Other Income

    Net interest and other income increased to $1.2 million in the nine month
period ended September 30, 1996 from $.5 million in the same period of 1995, an
increase of $.7 million principally due to the increase in cash available for
investment from the proceeds of the Company's public offering of Common Stock in
the fourth quarter of 1995 and the exercise of warrants and stock options during
the first nine months of 1996.

Net Loss

    The Company's net loss decreased to $11.6 million for the nine month period
ended September 30, 1996 from a net loss of $23.9 million for the same period of
1995, a decrease of $12.3 million. The net loss per share was $0.40 for the nine
month period ended September 30, 1996 compared to a net loss of $1.17 in the
same period of 1995. The number of weighted shares outstanding at September 30,
1996 was 28,710,000 as compared to 20,435,000 at September 30, 1995. The
decrease in the net loss was due to the increase in net sales of DOXIL and the
$5.3 million one-time upfront fee from Schering-Plough partially offset by an
increase in total operating expenses.


                                       9
<PAGE>   12
LIQUIDITY AND CAPITAL RESOURCES

    The Company's cash and cash equivalents and marketable investments at
September 30, 1996 were $35.8 million, a decrease of $14.5 million from $50.3
million at December 31, 1995. This decrease represents principally cash used by
operations and capital expenditures offset by cash provided by stock option and
warrant exercises. During the nine month period ended September 30, 1996, the
Company received approximately $9.0 million from the exercise of warrants and
stock options. Of this, approximately $3.0 million was due to the exercise of
warrants to purchase 705,714 shares of Common Stock at $4.25 per share and
approximately $2.0 million was due to the exercise of warrants to purchase
273,465 shares of Common Stock at $7.4328 per share. These warrants were
acquired by investors in private placement financings in March 1991 and May
1995, respectively. Warrants for 500,000 shares of SEQUUS Common Stock, which
expire in March 1997, remain outstanding from the March 1991 private placement.
Warrants for 838,380 shares, which expire in May 1999, remain outstanding from
the May 1995 financing. In addition, as of September 30, 1996, warrants for
808,320 shares of Common Stock at $7.425 per share, which expire in April 1998,
remained outstanding from a private placement financing in March and April 1995.
In February 1996, the Company gave notice to investors participating in a March
1995 private placement of the conversion to Common Stock of 480,000 shares of
Series A Convertible Reset Preferred Stock. Each share of Preferred Stock was
converted into 3.367 shares of Common Stock (rounded down to the nearest whole
share). The conversion was completed in April 1996.

    The Company's strategy has been to fund primarily from its own cash
resources the preclinical and clinical development of two of its proprietary
products, DOXIL and AMPHOTEC and the continued research and development of
additional STEALTH liposome products. This strategy requires significant
operating and capital expenditures, including the possible construction of a
pilot production facility which is currently in the planning phase.

    The Company believes that at planned spending rates its existing cash
balances, interest income earned thereon and revenues from operations will be
adequate to fund its planned activities through at least the next 12 months,
although it may seek additional financing sooner. There can be no assurance that
adequate financing will be available on satisfactory terms, if at all.

FACTORS THAT MAY AFFECT FUTURE RESULTS, EVENTS OR PERFORMANCE

    SEQUUS wishes to caution readers that the following important factors, among
others, may affect the Company's future results, events or performance and could
cause actual results, events or performance to differ materially from those
expressed in any forward-looking statements made by the Company in this report
or presented elsewhere by the Company from time to time.

Uncertainty of Market Acceptance

        The Company has received significant revenues from the sale of only one
product, DOXIL, and has limited experience in marketing its products. A
number of factors may limit the market acceptance of AMPHOTEC and any other
products developed by the Company and may limit continued or further market
penetration of DOXIL, including the timing of regulatory approval and market
entry relative to competitive products, the availability of alternate therapies,
the price of the Company's products relative to alternative therapies, the
availability of third-party reimbursement and the extent of marketing efforts by
third-party distributors or agents retained by the Company. Until quite
recently, no therapeutic product based on liposome or lipid-based technology was
commercially available in the United States. As a result, unanticipated side
effects or unfavorable publicity concerning any product incorporating liposome
or lipid-based technologies could have an adverse effect on the Company's
ability to obtain physician, patient or third-party payor acceptance and to sell
the Company's products. There can be no assurance of the Company's ability, or
the length of time required, to achieve commercialization of the Company's
products or that physicians, patients or third-party payors will accept liposome
products or any of the Company's products as readily as traditional forms of
medication or at all.

Uncertainty of Product Development

    The development of new pharmaceutical products is subject to a number of
significant risks. Potential products that appear to be promising at various
stages of development may not receive regulatory approval, reach the market or
achieve widespread use for a number of reasons. For example, DOXIL is being
clinically tested in various types of solid tumors. Although the Company
believes that preliminary results suggest activity in some but not all of these
tumors, these results are not conclusive nor are they predictive of future
results. Moreover, even when a drug does demonstrate activity, this does not
mean that it will prove sufficiently effective to be better than existing
therapies. The reasons for a product not being successful include the
possibilities that the potential product will be found insufficiently effective
or unduly toxic during preclinical testing or clinical trials, fail to receive
necessary regulatory approvals, be difficult to manufacture on a large scale, be
uneconomical to market or not achieve market acceptance, be inferior or
significantly later to market than competing products or be precluded from
commercialization by proprietary rights of third parties.

    There are a number of challenges the Company must address successfully to
develop commercial products in each of its development programs. The Company's
potential products will require significant additional research and development
efforts, including process development and significant additional clinical
testing, prior to any commercial use. There can be no assurance that the Company
will successfully address any of these technological challenges, or others that
may arise in the course of development. In addition, the Company may not have
sufficient resources to commercialize new products successfully.

    Successful product development requires, among other things, the design and
completion of clinical trials. The rate of completion of the Company's clinical
trials is dependent upon, among other factors, the rate of patient enrollment.
Patient enrollment is a function of many factors, including the size of the
patient population, the nature of the protocol, the Company's ability to manage
the clinical trial, the proximity of patients to clinical sites and the
eligibility criteria for the study. Several factors, such as delays in planned
patient enrollment may result in increased costs and delays, or termination of
clinical trials prior to completion, which could have a material adverse effect
on the Company's business, financial condition and results of operations.


                                       11
<PAGE>   14
Competition

    The drugs being developed by the Company compete with existing and new drugs
being created by pharmaceutical, biopharmaceutical and biotechnology companies.
Many of these companies, as well as university-related entities, both in the
United States and abroad are developing products based on improved drug delivery
technologies as well as novel therapeutics for the treatment of cancer,
infectious diseases and other indications targeted by the Company. Some of these
companies are active in the development of liposome and lipid-based research and
product development and many have financial and technical resources and
production and marketing capabilities substantially greater than those of the
Company. In addition, many of these companies have significantly greater
experience than the Company in preclinical and clinical development activities
and in obtaining regulatory approval to manufacture and market biopharmaceutical
products.

    The Company's two principal competitors in liposome drug delivery are
NeXstar Pharmaceuticals, Inc. ("NeXstar") and The Liposome Company ("TLC"), both
of which have received regulatory approval for products competitive with the
Company's products. NeXstar has received approval from the FDA with respect to
its liposome-based daunorubicin product (a liposome anthracycline formulation)
for use in first-line therapy of KS patients and has also received approval for
the same indication in 14 additional countries. DOXIL has been approved and is
being marketed in the U.S. as a second-line treatment for AIDS-KS and has been
approved in the 15 E.U. countries for both first-line and second-line therapy of
AIDS-KS (see "DOXIL Regulatory Status"). A NeXstar liposomal amphotericin B
product has been available in Europe since 1989 and has achieved substantial
market share as compared to the limited market penetration achieved to date by
the Company's lipid-based amphotericin B product, AMPHOTEC. In late 1995, TLC
launched its lipid-based amphotericin B product in the U.S., making it the first
lipid-based antifungal product available in the U.S. market. The Company's NDA
for AMPHOTEC is under review by the FDA (see "AMPHOTEC Regulatory Status"). TLC
also received approval for its amphotericin B product in several European
countries and has additional MAAs pending.

    SEQUUS believes that competition in all pharmaceutical products and in all
forms of drug delivery will continue to be intense. There can be no assurance
that other pharmaceutical companies will not develop more effective therapeutics
or drug delivery technologies than those of the Company or will not market and
sell their products more effectively than the Company.

Uncertainty of Pharmaceutical Pricing and Reimbursement

    The Company's business may be materially adversely affected by the
continuing efforts of worldwide governmental and third-party payors to contain
or reduce the costs of health care in general and drugs in particular. For
example, in most foreign markets, including markets the Company is seeking to
enter, pricing of prescription pharmaceuticals is subject to government pricing
control. In these markets, once marketing approval is received, pricing
negotiation could take as long as another six to 12 months or longer. In the
U.S., there has been, and the Company expects that there will continue to be, a
number of federal and state proposals to implement similar government pricing
control. In addition, an increasing emphasis on managed care and consolidation
of hospital purchasing in the U.S. has and will continue to put pressure on
pharmaceutical pricing. Such proposals, if adopted, and such initiatives could
decrease the price that the Company receives for any products it may develop and
sell in the future and thereby have a material adverse effect on the Company's
business, financial condition and results of operations. Further, to the extent
that such proposals or initiatives have a material adverse effect on
pharmaceutical companies that are collaborators or prospective collaborators for
certain of the Company's potential products, the Company's ability to
commercialize its potential products may be materially adversely affected. In
addition, price competition may result from competing product sales, attempts to
gain market share or introductory pricing schemes, which would have a material
adverse effect on the Company's business, financial condition and results of
operations.


                                       12
<PAGE>   15
    The Company's ability to commercialize biopharmaceutical products may depend
in part on the extent to which reimbursement for such products and related
treatments will be available from government health administration authorities,
private health insurers and other third-party payors. Significant uncertainty
exists as to the reimbursement status of newly approved health care products,
and third-party payors are increasingly challenging the prices charged for
medical products and services. There can be no assurance that any third-party
insurance coverage will be available to patients for any products developed by
the Company. Government and other third-party payors are increasingly attempting
to contain health care costs by limiting both coverage and the level of
reimbursement for new therapeutic products, and by refusing, in some cases, to
provide coverage for off-label uses of approved products, i.e., uses for
indications as to which the FDA has not granted marketing approval. Moreover,
reimbursement may be denied even for FDA-approved indications. If adequate
coverage and reimbursement levels are not provided by the government and
third-party payors for the Company's products, the Company's business, financial
condition and results of operations would be materially adversely affected.

No Assurance of Regulatory Approvals

    The production and marketing of the Company's products are subject to
rigorous manufacturing requirements, preclinical testing and clinical trials and
approval by the FDA, by comparable agencies in other countries and by state
regulatory authorities prior to marketing. The process of conducting clinical
trials and obtaining regulatory approval for a product typically takes a number
of years and involves substantial expenditures. 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
received regulatory approval in the U.S. for the commercial sale of only one of
its products. The Company may encounter significant delays or excessive costs in
its efforts to secure and maintain necessary approvals or licenses. Future
federal, state, local or foreign legislative or administrative acts could also
prevent or delay regulatory approval of the Company's products. There can be no
assurance that the Company will be able to obtain or maintain the necessary
approvals for manufacturing or marketing the Company's products for current or
expanded indications or that the data it obtains in clinical trials will be
sufficient to establish the safety and efficacy of its products. Even if the
Company obtains regulatory approval for any particular product, there can be no
assurance that it will be economically feasible for the Company to commercialize
such product. In addition, identification of certain side effects after a drug
is on the market or the occurrence of manufacturing problems could cause
subsequent withdrawal of approval, reformulation of the drug, additional
preclinical testing or clinical trials, and changes in labeling of the product.
Failure to obtain or maintain requisite governmental approvals, failure to
obtain approvals of the clinically intended uses or the identification of side
effects could delay or preclude the Company from further developing particular
products or from marketing its products, or could limit the commercial use of
its products, which would have a material adverse effect on the Company's
business, financial condition and results of operations.

DOXIL Regulatory Status

    In November 1995, SEQUUS received marketing clearance from the FDA for use
of DOXIL in the treatment of AIDS-KS patients whose KS has progressed on prior
chemotherapy or in patients who are intolerant to such therapy. In December
1995, the Company launched DOXIL in the U.S., using its own marketing and sales
force. The marketing clearance was provided in accordance with the FDA's
procedures for Accelerated Approval of New Drugs for Serious or Life-Threatening
Illnesses. Accelerated approval regulations require that an applicant study an
investigational drug following product launch to verify and describe the drug's
clinical benefit. The Company is conducting a post-marketing clinical trial
designed to meet accelerated approval requirements. Under FDA accelerated
approval regulations, the FDA may withdraw approval following product launch if
the Company fails to show due diligence in conducting the post-marketing
clinical trial or if this clinical trial fails to demonstrate clinical benefit
to the FDA's satisfaction. There can be no assurance that the Company will be
able to conduct a satisfactory post-marketing clinical trial.


                                       13
<PAGE>   16
    In June 1996, the Company was granted marketing authorization for DOXIL
under the tradename CAELYX, in the 15 member states of the EU, for both
first-line and second-line treatment of AIDS-KS in patients with low CD4 counts
and extensive mucocutaneous or visceral disease. The drug may be used as
first-line systemic chemotherapy, or as second-line chemotherapy, in AIDS-KS
patients with disease that has progressed with, or in patients who are
intolerant to, prior combination chemotherapy comprising at least two of the
following agents: a Vinca alkaloid, bleomycin, and doxorubicin (or another
anthracycline). The Company's distribution partner, Schering-Plough (see
"Dependence on Third Party Distributors and Agents"), has begun pricing
discussions with the appropriate agencies in selected countries where pricing
approval is required. There can be no assurance that Schering-Plough will be
able to negotiate a satisfactory price for DOXIL in the EU countries.

AMPHOTEC Regulatory Status

    SEQUUS has received marketing authorization approval for AMPHOTEC, under the
tradename AMPHOCIL, in Argentina, Austria, Brazil, Denmark, the Czech Republic,
Finland, Iceland, Ireland, Italy, the Netherlands, Russia, Singapore, Slovenia,
the Slovak Republic, Sweden, Turkey and the U.K.. AMPHOTEC is indicated for the
treatment of severe and/or deep systemic mycoses in cases where toxicity or
renal failure precludes the use of conventional amphotericin B and in cases
where prior systemic antifungal therapy has failed. MAAs for AMPHOTEC, submitted
by the Company and Zeneca, are under assessment in a number of countries,
including other European countries, except in Norway where the MAA was
withdrawn. In September 1995, the CPMP reviewed the Company's multi-state
application for product marketing approval. Germany, France, Spain, Greece and
Luxembourg did not accept the MAA. SEQUUS believes approval will be forthcoming
in Portugal. However, there can be no assurance that approvals in any additional
countries, including pricing approvals, will be forthcoming on a timely basis,
or at all. In addition, after the CPMP meeting, following further consideration
by the Commission of Medicines in Belgium, the Company has accepted the option
of a marketing authorization approval for AMPHOTEC in a limited indication.

    In November 1995, the Company submitted to the FDA an NDA for AMPHOTEC based
upon certain data from open label clinical trials, which was accepted for filing
in January 1996. There can be no assurance that the FDA will determine that the
Company's NDA provides sufficient evidence of safety and efficacy in humans to
support FDA approval or that the NDA will be approved on a timely basis, or at
all.

Dependence on Third-Party Distributor and Agents; Limited Marketing and Sales
Experience

    In September 1996, the Company entered into an exclusive arrangement with
Schering-Plough under which Schering-Plough will distribute, market and sell
DOXIL worldwide, under the tradename CAELYX(TM), except for the United States,
Japan and certain small markets subject to prior distribution arrangements.
Under the terms of the agreement, SEQUUS will receive payments for product sales
to Schering-Plough. In addition, Schering-Plough will fund a portion of the
clinical development program for DOXIL, conduct clinical trials for a solid
tumor indication, apply for regulatory approval in the Schering-Plough
territories for all new indications, and assist with pharmacoeconomic studies.
The Company's future sales of DOXIL to Schering-Plough will depend upon the
success of Schering-Plough's marketing efforts, the rate at which the product
penetrates the existing approved markets (see "DOXIL Regulatory Status") as well
as the timing of additional approvals, including pricing approvals, in other
countries, if any.

    In 1995, a substantial portion of the Company's product revenues came from
sales either to a third-party distributor (Zeneca) or through third-party
agents. For the fiscal year ended December 31, 1995, 41% of the Company's
product sales represent sales of AMPHOTEC to Zeneca as compared to 91% for 1994.
A significant portion of these sales of AMPHOTEC reflect pipeline-filling
(inventory) orders. The Company did not ship any AMPHOTEC to Zeneca in 1995
after the first quarter. Five shipments of AMPHOTEC were made in the first nine
months of 1996 and the Company anticipates only limited sales to Zeneca for the
foreseeable future. The level of the Company's future sales of AMPHOTEC to
Zeneca will 


                                       14
<PAGE>   17
depend upon the rate at which the product penetrates the existing approved
markets (see "AMPHOTEC Regulatory Status") as well as the timing of additional
approvals in other countries, if any. Sales of AMPHOTEC to date have been below
expectations. In July 1996, SEQUUS announced that it had reacquired from Zeneca
all international marketing and distribution rights for AMPHOTEC except for nine
European countries to which Zeneca had retain such rights (Denmark, Finland,
Holland, Iceland, Ireland, Italy, Portugal, Sweden and the United Kingdom). In
exchange for the return to SEQUUS of marketing and distribution rights
throughout the rest of the world, SEQUUS agreed to restructure certain future
milestone payments specified in the original 1993 agreement, adjust the pricing
terms for AMPHOTEC to provide greater competitive flexibility, and exchange
certain inventory.

    The Company expects to market and sell its products directly, or possibly
co-promote them with strategic partners, in the U.S. In this regard, SEQUUS
currently employs a sales force of 32 professionals to market DOXIL, which the
Company intends to expand if marketing clearance is obtained for AMPHOTEC. This
group is experienced in the sale of pharmaceutical and biotechnology products to
physicians, hospitals and clinics, including managed care providers, and in
facilitating reimbursement with third-party payors. Further development of such
a marketing and sales organization will require significant additional
expenditures, management resources and time. The Company has limited experience
marketing and selling its products. In addition, the loss of certain key sales
personnel would delay and adversely affect the sales effort and would have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that the Company will be able
to implement its marketing plan successfully. If the Company enters into any
marketing partnerships in the U.S., such as those currently under consideration,
this would significantly reduce the Company's margins on these products. There
can be no assurance that the Company will be able to establish such a marketing
and sales organization successfully or manage its marketing organization
successfully.

Product Liability

    Testing, manufacturing, marketing and use of the Company's products will
entail substantial risk of product liability. The Company currently maintains
product liability insurance in an amount of $10 million per occurrence and $10
million in the aggregate. A single product liability claim could exceed the $10
million coverage limit, and there is a possibility of multiple claims. There can
be no assurance that the amount of insurance the Company has obtained against
the risk of product liability will be adequate, that the amount of such
insurance can be renewed or that the amount and scope of any coverage obtained
will be adequate to protect the Company in the event of a successful product
liability claim. The Company's business could be materially adversely affected
by one or more successful product liability claims.

    In addition, with respect to the sale of products in the U.S., the Company
believes it has significantly greater risk in connection with product liability
claims due to the greater frequency of lawsuits and higher claims paid in courts
in the U.S. as opposed to most other countries. The Company is required by
governmental regulations to test its products even after they have been sold and
used by patients. As a result of such tests, the Company may be required to, or
may determine that it should, recall products when most of such products have
already been sold. Such later testing and product recalls may increase the
Company's potential exposure to product liability claims.

Dependence on Third-Party Manufacturer; Manufacturing Risks

    The Company's present internal manufacturing capabilities are limited to
producing products for preclinical development. The Company is dependent on Ben
Venue, a United States-based contract manufacturer, to manufacture
commercial-scale quantities of AMPHOTEC and DOXIL pursuant to supply agreements.
Under these agreements the Company has agreed to indemnify Ben Venue against
certain liabilities. As of September 1996, the Company and Ben Venue have
manufactured 32 commercial-scale batches of DOXIL, including the three
registration batches which are required as part of the FDA's NDA approval
process. There can be no assurance that Ben Venue will continue to meet FDA or
product specification standards or that the Company's manufacturing goals can be
met in a consistent and timely 


                                       15
<PAGE>   18
manner. There is only a limited number of other manufacturers with the
capability of manufacturing AMPHOTEC and DOXIL, and any alternative manufacturer
would require regulatory qualification to manufacture the product which would
likely take several months.

    The Company has not qualified alternative manufacturers for its products. In
the event of any interruption of supply from the contract manufacturer due to
regulatory or other causes, there can be no assurance that the Company could
make alternative manufacturing arrangements on a timely basis, if at all. Such
an interruption would have a material adverse effect on the Company's business,
financial condition and results of operations.

    The Company relies on certain suppliers of key raw materials to provide an
adequate supply of such materials for production of finished products. Certain
materials are purchased from single sources. In particular, amphotericin B and
doxorubicin HCI are currently each supplied to the Company by single sources,
and the number of alternative sources is severely limited. For example, the
Company has a five-year, sole-source supply agreement with Meiji Seika Pharma
International, Ltd. to supply the Company with doxorubicin HCI for DOXIL. There
can be no assurance that the doxorubicin HCI supplied under the agreement will
continue to meet FDA requirements applicable to DOXIL, which could delay or
prevent future sales of DOXIL, if any, by the Company. Although the Company has
supply agreements in place with the suppliers of its key raw materials, the
number of alternative qualified suppliers of key raw materials required for the
manufacture of AMPHOTEC and DOXIL is limited. The disqualification or loss of a
sole source supplier could have a material adverse effect on the Company because
of a delay or inability in obtaining and qualifying an alternate supplier and
the costs associated with such delay and in finding and qualifying an alternate
supplier. Regulatory requirements applicable to pharmaceutical products tend to
make the substitution of suppliers costly and time consuming. The unavailability
of adequate commercial quantities, the loss of a supplier's regulatory approval,
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
and its results of operations.

Patents and Trade Secrets

    There has been increasing litigation in the biomedical, biotechnology and
pharmaceutical industries with respect to the manufacture, use and sale of new
therapeutic products that are the subject of conflicting patent rights. A
substantial number of patents relating to liposomes have been issued to, or are
controlled by, other public and private entities, including academic
institutions. In addition, others, including competitors of SEQUUS, may have
filed applications for, or may have been issued patents or may obtain additional
patents and proprietary rights relating to products or processes competitive
with those of SEQUUS. The patent positions of pharmaceutical, biopharmaceutical,
biotechnology and drug delivery companies, including SEQUUS, are uncertain and
involve complex legal and factual issues. Additionally, the coverage claimed in
a patent application can be significantly reduced before the patent is issued.
As a consequence, the Company does not know whether any of its patent
applications will result in the issuance of patents or whether any of the
Company's patents will provide significant proprietary protection or will be
circumvented or invalidated. Since patent applications in the United States are
maintained in secrecy until patents issue, and since publication of discoveries
in the scientific or patent literature often lag behind actual discoveries, the
Company cannot be certain that it was the first inventor of inventions covered
by its pending patent applications or that it was the first to file patent
applications for such inventions. Moreover, the Company may have to participate
in interference proceedings to determine priority of invention, which could
result in substantial cost to the Company, even if the eventual outcome is
favorable to the Company. There can be no assurance that any patents owned or
controlled by the Company will protect SEQUUS against infringement litigation or
afford commercially significant protection of the Company's technology. Almost
none of the Company's patents has been tested in court to determine their
validity and scope. Moreover, the patent laws of foreign countries differ from
those of the United States and the degree of protection, if any, afforded by
foreign patents may, therefore, be different.


                                       16
<PAGE>   19
    In November 1991, the Company received a letter from TLC bringing to SEQUUS'
attention TLC's United States Patent No. 5,059,591 (the "'591 Patent")
containing claims directed to amphotericin B/sterol compositions and their
method of use. Subsequently, SEQUUS' patent counsel delivered an opinion to the
Company that, among other things, AMPHOTEC does not infringe any valid claim of
the '591 Patent. However, no assurance can be given that TLC will not make a
claim against SEQUUS with respect to the '591 Patent, which could have a
material adverse effect on the Company's ability to commercialize AMPHOTEC.

    The Company has a practice of monitoring patents and other developments in
the liposome field. To the extent that the Company becomes aware of patents of
other parties which the Company's processes or products might infringe, it is
the Company's practice to seek review of such patents by the Company's patent
counsel. With respect to the Company's DOXIL product, SEQUUS is aware of TLC's
United States Patent No. 5,077,056 (the "056 Patent") relating to the loading of
therapeutic drugs into liposomes. The Company's patent counsel has rendered an
opinion that DOXIL would not infringe any valid claim of this patent.
International equivalent patents to the '056 Patent are now undergoing
opposition proceedings in the European and Japanese patent offices and the
Company is party to such proceedings. The Company is also aware of TLC's United
States Patent No. 5,008,050 relating to reducing liposome size by extrusion, and
NeXstar's United States Patent No. 5,435,989 relating to targeting of liposomes
to solid tumors. The Company's patent counsel has rendered an opinion that its
DOXIL product would not infringe any valid claim of either of these patents. In
addition, the Company is aware of certain patents covering lyophilization of
liposomes. Neither of the Company's principal products involves the
lyophilization of liposomes.

    Generally, the Company refers patents to its patent counsel for review. Even
if the Company's patent counsel renders advice that the Company's products do
not infringe any valid claim under such patents, there can be no assurance that
any third party will not commence litigation to enforce such patents or that the
Company will not incur substantial expense, or that it will prevail, in any
patent litigation.

    The Company has been required to defend itself in patent litigation in the
past and the uncertainties inherent in any other lawsuit that may be commenced
in the future with respect to any alleged patent infringement by the Company
make the outcome of any such litigation difficult to predict. The Company may
decide to pay a royalty or make other concessions to settle a patent dispute. In
the event of litigation, there can be no assurance that the Company will be
successful. A judgment adverse to the Company in any such litigation could
materially adversely affect the Company's business, financial condition and
results of operations, and the expense of such litigation may be substantial,
whether or not the Company is successful in such litigation.

    The Company relies on unpatented trade secrets and proprietary know-how to
protect certain aspects of its production and lipid purification technologies
and other proprietary information. Although SEQUUS has entered into
confidentiality agreements with its employees, consultants, representatives and
other business associates, there can be no assurance that trade secrets and
know-how will remain undisclosed or that similar trade secrets or know-how will
not be independently developed by others.

History of Operating Losses; Need for Additional Financing

    The Company has incurred losses in each year since its inception and has
accumulated approximately $145.0 million in net losses through September 30,
1996, including a net loss of $11.6 million in the first nine months of 1996.
The Company to date has generated limited revenues. There can be no assurance
that revenues from product sales will be significant or sufficient to fund
operations. Owing to expenditures associated with self-funded research,
preclinical and clinical programs, marketing expenses and other activities
related to seeking regulatory approval and achieving commercialization of its
products, the Company expects to continue to incur operating losses. Additional
financing may be required to fund the Company's continuing operations and
product and business development activities in the form of debt or equity
securities or bank financing. There can be no assurance that such financing will
be available on 


                                       17
<PAGE>   20
acceptable terms, if at all. The unavailability of such financing could delay or
prevent the development, testing, regulatory approval, manufacturing or
marketing of some or all of the Company's products and could have a material
adverse effect on the Company.

Dependence on Key Personnel; Management Transition

     The Company's success depends largely upon its ability to attract and
retain qualified scientific, engineering, manufacturing, sales and marketing and
management personnel. The Company faces competition for such personnel from
other companies, academic institutions, government entities and other
organizations. There can be no assurance that the Company will be successful in
hiring or retaining such personnel. Four of the key executive officers of the
Company have joined the management team in the past 18 months. The new
management team will face significant challenges in transitioning the Company
from research and development to manufacturing and marketing if the Company's
products obtain regulatory approval. There can be no assurance that the
management team can successfully manage the transition of the Company's
business.

Hazardous Materials

    As with many biopharmaceutical companies, the Company's research and
development involves the controlled use of hazardous materials and chemical
compounds. There can be no assurance that the Company's safety procedures for
handling and disposing of such materials will comply with the standards
prescribed by federal, state and local regulations or that it will not be
subject to the risk of accidental contamination or injury from these materials.
In the event of such an accident, the Company could be held liable for any
damages that result and any such liability could materially adversely affect the
Company's business, financial condition and results of operations.

Volatility of Stock Price

    The market price of the Common Stock, like the stock prices of many publicly
traded biopharmaceutical companies, has been and may continue to be highly
volatile. A variety of events, both concerning and unrelated to the Company and
the biopharmaceutical industry, such as the level of sales of the Company's
products, problems with clinical development of the Company's potential
products, announcements of technological innovations, regulatory developments or
new commercial products by the Company or its competitors, government
regulation, delays or other developments relating to regulatory approvals,
developments or disputes relating to patent or proprietary rights, product
liability claims, as well as period-to-period fluctuations in the Company's
financial results, may have a significant negative impact on the market price of
the Common Stock. Although the Common Stock trades on the Nasdaq National
Market, the trading volume has fluctuated and at times has been quite low. Any
large sale of securities of the Company could have a significant adverse effect
on the market price of the Common Stock.

                                       7
<PAGE>   13

In the event that Agreement Product is permissibly sold pursuant to Section 7.11
as part of a combination product, i.e., sold in a package containing other
products ("Combination Product"), Net Sales for such Combination Product will be
calculated by multiplying actual Net Sales of such Combination Product by the
fraction A/(A+B) where A is the invoice price of the Agreement Product if sold
separately by or on behalf of Schering and B is the invoice price of any other
products in the Combination Product if such products are sold separately by or
on behalf of Schering. In the event that the Agreement Product is sold in the
form of a Combination Product and one or more of such other products included
within the Combination Product are not sold separately, then the Net Sales for
such Combination Product shall be calculated by multiplying the number of units
of Agreement Product sold in the form of a Combination Product by the Average
Net Selling Price for Agreement Product sold separately in the country in
question, during the period for which Net Sales is being calculated. For the
purposes hereof, "Average Net Selling Price" shall mean, for the country in
question, the Net Sales of the quantity of Agreement Product sold separately
divided by the number of units of Agreement Product represented in such Net
Sales. If the Agreement Product is not sold separately in such country, then the
parties shall agree in good faith on an equitable Average Net Selling Price for
the Agreement Product to be used in the foregoing calculation.

         1.17 "Regulatory Authorities" shall mean any national, supra-national
(e.g., the European Commission, the Council of the


                                       8

approvals of the Agreement Product including any marketing authorizations based
upon such approvals and pricing, third party reimbursement or labelling
approvals that are necessary for the manufacture, distribution, use or sale of
Agreement Product in a regulatory jurisdiction.

         1.18 "Schering Confidential Information" shall mean (a) any and all
methods, policies and procedures related to the distribution, marketing and sale
of Agreement Product and (b) all technical data, ideas, information, materials,
instructions, processes, formulae, expert opinion and other know-how presently
owned or controlled by or developed by, or on behalf of, Schering or its
Affiliates during the term of this Agreement which relates to Schering's
activities in connection with the Agreement Product pursuant to this Agreement
and the internal business practices or business information of Schering.

the Agreement Product and (b) any inventions or know-

         1.21 "Trademarks" shall mean a trademark or trademarks owned by Sequus

the Territory, which marks shall include CAELYX(TM) and such other marks that,
once they have been agreed by the parties, shall also be set forth in Schedule B
attached hereto and forming a part of this Agreement, which Schedule may be
amended from time to time by written agreement between the parties.

                                 II. APPOINTMENT

4.1(h) shall in no way diminish Schering's obligation to transfer such
Governmental Permits to Sequus as and when required by Section 4.1(g) hereof.

                  (i) The grant to Schering of the right, title and interest in
and to the Governmental Permits under this Section 4.1 shall not be construed,
either alone or together with the other provisions of this Agreement, to
constitute a license from Sequus to Schering, under any intellectual property
rights owned or controlled by Sequus to make, use or sell the Agreement Product.

certificates of origin.  Sequus shall pay all freight and shipping on account
of the supply of bulk vials of Agreement Product by Sequus to a single delivery
site in the EEA and a single delivery site for Canada, as reasonably designated

satisfied. Notwithstanding the foregoing, the parties recognize that extenuating
circumstances may arise that may excuse Schering from the commencement of

pricing, pricing reimbursement, or labelling. In the event Schering determines
that unfavorable pricing, pricing reimbursement or labelling conditions exist,
Schering shall be excused from its obligation to commence marketing of the
Agreement Product. Any other reason which Sequus finds acceptable in its
reasonable judgment may also excuse Schering's obligation to commence marketing
of the Agreement Product. Schering shall also be excused from its obligation to
commence marketing of the Agreement Product if Sequus is not meeting its
obligation to supply Agreement Product under Article VI of this Agreement.

freight so as to arrive on the next business day after being sent. If the
Agreement Product is not in inventory, Sequus will take all reasonable steps to
ensure expeditious manufacture of conforming Agreement Product which will be
shipped air freight on the next shipping day after completion of manufacture so
as to arrive on the next business day.

                  (g) ** At Sequus' expense, the non-conforming shipment shall
be returned to Sequus, or disposed of by Schering, at Schering's option, upon
final determination in accordance with Section 6.2(d) above that it does not
meet the Specifications.

                  (h) Each party agrees to notify the other within two (2)
business days of its receipt of notification of any inquiries, notifications, or
inspection activity by any Regulatory Authority, governmental agency or
authority in regard to the Agreement Product or the manufacturing facilities
therefor. Sequus shall provide a reasonable description to Schering of any such
governmental inquiries, notifications or inspections promptly (but in no event
later than five (5)


                                       37

calendar days) after notification of completion of such visit or inquiry. Sequus
shall furnish to Schering, (i) within two (2) business days after receipt, any
report or correspondence issued by the Regulatory Authority or governmental
authority in connection with such visit or inquiry, including but not limited
to, any FDA form 483, Establishment Inspection Reports or warning letters and
(ii) at the same time it provides to any Regulatory Authority or governmental
authority, copies of any and all documents, responses or explanations relating
to items set forth above, in each case purged only of trade secrets of Sequus
that are unrelated to the obligations under this Agreement or are unrelated to
the Agreement product. In the event such governmental agency or authority
requests or requires any action to be taken to address any citations, Sequus
agrees, after consultation with Schering, to take such action as necessary to
address such citations, and agrees to cooperate with Schering with respect to
any such citation and/or action taken with respect thereto.

                  (i) Sequus shall ** obtain the right for Schering to
visit, during normal business hours and with reasonable advance notice (a
minimum of thirty (30) business days) Sequus' manufacturing facility (including
Ben Venue Laboratories Inc. ** or their successors), under customary
confidentiality conditions, for the purpose of observing the manufacturing,
packaging, testing, and warehousing of the Agreement Product and to inspect for
compliance with cGMPs and other applicable regulatory requirements.

         6.3 Forecasts.

                  (a) The parties will work together to establish mechanisms to
ensure efficient, fair, equitable and cost effective supply logistics and
materials management. As soon as practicable, but not later than thirty (30)
days after the Effective Date, Schering shall provide Sequus with a written
forecast (by quarter) of the quantity of Agreement Product that Schering desires
to have delivered to it during the period beginning on the Effective Date and
ending September 30, 1996 (the "Initial Period") and for the following five (5)
consecutive calendar quarters commencing with October 1, 1996. The forecast for
the Initial Period shall not be binding, but the forecast for the ** beginning
October 1, 1996 shall represent a binding commitment of Schering to purchase and
Sequus to supply such forecasted amount of Agreement Product. Thereafter, at
least fifteen (15) days before the end of each subsequent calendar quarter,
Schering shall provide a written, updated forecast (by quarter) of the quantity
of Agreement Product that Schering desires to have delivered to it during the
following five (5) consecutive calendar quarters. Each successive forecast shall
update the forecast previously given for the last three (3) quarters covered and
add a forecast for the quarter following immediately thereafter, to enable
Sequus to have sufficient


                                       39
<PAGE>   45

information to schedule its or its sub-contractors' manufacturing operations to
meet Schering's forecasted Requirements of the Agreement Product. Sequus
acknowledges that such forecasts are only estimates of Schering's purchase
Requirements of the Agreement Product and that Schering shall not be bound by
any such estimate, except that the ** of each successive forecast so provided
shall likewise represent a binding commitment of Schering to purchase and of
Sequus to supply such forecasted quantity of Agreement Product in a timely
manner, subject to adjustment within the limits set forth in Section 6.3(c)
hereof. Schering shall order and maintain all reasonable inventories of the
Agreement Product, having due regard to current and forecasted sales volumes.
Schering shall issue to Sequus firm purchase orders for each delivery not later
than three (3) months prior to the requested delivery date.

                  (b) Schering shall not be permitted to return any Agreement
Product meeting Specifications therefor that Schering has ordered and Sequus has
supplied hereunder, without the prior written consent of Sequus.

                  (c) Sequus shall not be obligated to supply that quantity of
Agreement Product in any calendar quarter that is more than ** of the last
binding forecast provided by Schering for the calendar quarter in question;
provided, however, that Sequus shall endeavor to take all reasonable steps to
fill binding orders for Agreement Product in excess of such amount.

                  (d) If any time Sequus experiences a shortage of Agreement
Product supply and the available supplies of Agreement Product are not
sufficient to satisfy all of Schering's


                                       40
<PAGE>   46

Requirements for the Agreement Product in the Territory, Sequus shall allocate
its available worldwide supplies (including inventory in excess of customary
supplies) equitably among its own requirements and those of its licensees and
distributors, including Schering, based on the purchasing history of such
entities during the prior six (6) month period.

                  (e) If at any time Sequus is of the opinion that it may not be
able to meet future binding orders from Schering for Agreement Product ** it
shall notify Schering in writing, and the parties shall in good faith cooperate
and endeavor to make appropriate arrangements for a continuous and adequate
supply of Agreement Product from Sequus to Schering. Consistent with Sequus'
obligations under Section 6.3(c), if Sequus is unable to supply at least ** of
the quantities of Agreement Product ordered by Schering in any two (2)
consecutive quarters, based on Schering's good faith estimates of its future
Requirements, Schering shall be relieved of its obligation to purchase that
portion of its Requirements of Agreement Product from Sequus that Sequus is
unable to supply, for so long as such inability to supply continues. ** In the
event that Sequus is unable to supply Agreement Product as provided in this
Section 6.3(e), Sequus shall be responsible for **. At such time as Sequus
reasonably demonstrates to Schering that it is able to again supply all of
Schering's Requirements, Schering shall be permitted to ** have manufactured on
Sequus' behalf, for such period of time thereafter **, using generally accepted
accounting principles normally used by Schering in keeping its own books and
records. Thereafter, Schering shall ** terminate its supply from


                                       41
<PAGE>   47

a third party, **, and subsequently continue the purchase of its Requirements of
Agreement Product from Sequus in accordance with the terms of this Agreement. If
the quantity of Agreement Product that Sequus is unable to supply is so limited
that it would be an excessive financial burden on Schering to ** have
manufactured, such limited quantity, the parties shall meet, after Sequus is
notified by Schering of such circumstance, and in good faith seek to reasonably
resolve the matter.

                  (f) If Sequus discloses Know-how pursuant to this Agreement
and/or Know-how related to manufacturing of the Agreement Product to Schering **
then, for the term of this Agreement and for three (3) years thereafter,
Schering and its Affiliates shall not **.

                  (g) **


                                       42
<PAGE>   48

derivation of such Know-how, Sequus Confidential Information or technology
provided by Sequus; and (iii) Schering shall establish protective measures
within its organization and the third party manufacturer to protect any
Know-how, Sequus Confidential Information or technology from disclosure.

         6.4 Delivery Terms. All Agreement Product shall be sold in bulk vials
and be delivered **.

         6.5 Scheduling of Delivery. Sequus shall schedule the timely
manufacturing and shipment of the Agreement Product pursuant to Schering's firm
purchase orders. Should Sequus, at any time during the course of this Agreement,
have reason to believe that it will be unable to meet Schering's requested
delivery dates, Sequus will promptly notify Schering, in writing, stating the
reasons for the delay. Such notification will not be deemed a waiver of Sequus'
obligations set forth in Section 6.3(e).

         6.6 **. Within a reasonable time (which shall not exceed ** plus any
delay associated with approval of the site of manufacture by a Regulatory
Authority) after Annual Net Sales attain a level of **, or if a restriction is
imposed upon (a) manufacturing that would prevent Sequus from meeting its supply
obligation hereunder or (b) exporting the Agreement Product out of the country
where it is manufactured, then Sequus shall establish **. Schering, or a
Schering Affiliate, shall be considered in good faith by Sequus as **, provided,
that Schering, or the Schering Affiliate, as the case may be, ** and is able 
to reasonably demonstrate ** that it is able to meet all **.

                             VII. PRICE AND PAYMENTS

         7.1 Price. Subject to adjustment as provided in Section 7.4 below or as
provided in Section 7.2, the price per vial of Agreement Product to be paid by
Schering for the Agreement Product sold by Sequus to Schering in any Fiscal Year
shall be equal to the sum of (i) ** of Annual Net Sales in such Fiscal Year for
Annual Net Sales up to and including ** and (ii) ** of Annual Net Sales in such
Fiscal Year for Annual Net Sales in excess of **, divided by the total numbers
of vials of Agreement Product included in such Annual Net Sales; provided,
however, that upon receipt from the European Commission or applicable Regulatory
Authority of marketing approval for the Agreement Product for the treatment of
**, the percentage of Annual Net Sales used for the foregoing calculation shall
be fixed at **, regardless of the level of Annual Net Sales, for the remainder
of the term of this Agreement. ** In no event shall the payments due under 
this Section 7.1 plus payments due under Section 3.11 exceed ** of Annual Net 
Sales prior to marketing approval in the EU for the treatment of **.

         7.2 Floor Price.

                  (a) Notwithstanding Section 7.1 above, in the event the price
Schering is to pay Sequus for Agreement Product per twenty (20) milligram-ten
(10) milliliter vial of Agreement


                                       44
<PAGE>   50

Product supplied by Sequus to Schering would be less than **, or ** the parties
shall meet to discuss the economic implications for Sequus. In the event the
parties are unable to agree on actions to modify the economic implications for
Sequus, Sequus shall supply the Agreement Product to Schering at the price
specified in Section 7.1 above as long as such price is not below **. The
foregoing price shall be adjusted on an annual basis each January 1st by the
annual percentage change in the Producer's Price Index for Pharmaceutical
Products reported in the month of June of the year immediately preceding the
year in which the adjustment is to be effective.

                  (b) In the event the price specified in Section 7.1 above
would result in a price below **, Schering shall notify Sequus to that effect.
However, Sequus shall continue to supply Schering at the price specified in
Section 7.1 above as long as such price is not below Sequus' **. In the event
this results in inequitable economics between the parties from what was
originally contemplated, the parties shall discuss reasonable changes to the
economic structure that might restore the original economic distribution. While
such discussions are ongoing and in the event such discussions break down,
Sequus shall continue to supply Agreement Product to Schering at the price
specified in Section 7.1 above as long as such price is not below Sequus' **.
Sequus' ** for Agreement Product shall be determined consistent with Schedule F
attached hereto.

                  (c) If the price specified in Section 7.1 above would result
in a price to Sequus below its ** the parties shall in good faith endeavor to
reach agreement on a new price that would


                                       45
<PAGE>   51

maintain an equitable economic benefit to each party or other remedy as the
parties agree.

                  (d) All calculations of price per milligram of Compound shall
be determined from the price in Dollars per vial of Agreement Product divided by
the quantity of Compound in milligrams specified on the label of the Agreement
Product.

         7.3 Provisional Price. The initial price for the purchase of the
Agreement Product shall be set as soon as practicable, but in no event later
than within thirty (30) days from the Effective Date and by September 30th of
each Fiscal Year commencing in 1997. The intention is that the provisional price
will be a close approximation to the expected final purchase price for the next
Fiscal Year. In the event that the parties cannot so agree, the provisional
price will be ** of the average net selling price on a per vial basis in the
preceding second calendar quarter.

         7.4 Reconciliation. At the end of each calendar quarter, Schering shall
make a calculation showing whether an adjusting payment is necessary between the
two parties applying Section 7.1, at a total purchase price of ** of Net Sales
for Net Sales for the Fiscal Year which are less than or equal to **, and ** of
Net Sales, for those Net Sales for the Fiscal Year that exceed **, as
appropriate prior to receipt from the European Commission of marketing approval
for the treatment of ** and ** of Net Sales subsequent to such approval, divided
by the number of vials sold, to calculate the actual supply price(s). This will
be compared with the provisional supply price. A reconciliation statement shall
be supplied by Schering to Sequus by the last working day of the month following
the end of each calendar quarter and the


                                       46
<PAGE>   52

difference between the actual supply price and the provisional price multiplied
by the total number of vials sold in the calendar quarter will be paid by
Schering or Sequus to the other (as the case may be) within sixty (60) days
after the end of the calendar quarter in question.

         7.5 Samples and Clinical Supplies. Agreement Product to be used by
Schering for registration trials, as set forth in this Agreement, shall be
provided to Schering **. Agreement Product to be used by Schering as samples and
as product for non-registration trials shall be supplied to Schering at a price
of ** per twenty (20) milligram-ten (10) milliliter vial. At such time as Sequus
scales up its manufacturing process for the Agreement Product to a ** batch
size, the foregoing price shall be ** per twenty (20) milligram-ten (10)
milliliter vial, which may be adjusted up or down based on changes to Sequus' **
such that it reflects Sequus' actual **. The foregoing prices shall be adjusted
on an annual basis each January 1st by the annual percentage change in the
Producer's Price Index for Pharmaceutical Products reported in the month of June
of the year immediately preceding the year in which the adjustment is to be
effective. **

         7.6 Sales Reports. Within thirty (30) days following the close of each
calendar quarter, Schering shall provide Sequus with a statement for each
country of the Territory showing the total amount of sales of Agreement Product
and the number of vials sold for Agreement Product for the quarter. Upon request


                                       47
<PAGE>   53

by Sequus, Schering shall supply the currency exchange rate(s) used in
calculating the payments made hereunder pursuant to Section 7.7(b). Schering
shall also provide Sequus within sixty (60) days after the close of each Fiscal
Half-Year with a statement showing the number of samples distributed in each
country by or on behalf of Schering.

         7.7 Method of Payment.

                  (a) Sequus will invoice Schering in United States Dollars for
each and every shipment of Agreement Product, and payment for all such
quantities so shipped, and any other payments due under this Agreement, shall be
made in United States Dollars by bank transfer within thirty (30) days of
invoice date, in accordance with written instructions (not inconsistent
herewith) that Sequus shall give to Schering.

                  (b) Payments based on Net Sales of Agreement Product in any
country of the Territory shall be calculated by converting the Net Sales in each
country into United States Dollars at the rates of exchange used by Schering's
United States reporting parent Affiliate to report its sales for public,
financial reporting purposes and multiplying the resultant amount by the
appropriate percentage specified in Section 7.1.

                  (c) If, due to restrictions or prohibitions imposed by a
national or international authority in a country where Schering has no presence
or has no Affiliate or Designated Subdistributor presence, payments in such a
country of the Territory cannot be made as aforesaid, then the parties shall
consult with a view to finding a prompt and acceptable solution, and Schering
shall, from time-to-time, deal with such monies as Sequus may lawfully


                                       48
<PAGE>   54

direct at no additional out-of-pocket expense to Schering. Notwithstanding the
foregoing, if payments accrued on Net Sales in such a country cannot be remitted
to Sequus for any reason within six (6) months after the end of the calendar
quarter during which they are earned, then Schering shall be obligated to
deposit the payments in a bank account in such country in the name of Sequus.

                  (d) **

         7.8 Approval Payment. In addition to any other amounts paid by Schering
to Sequus pursuant to this Agreement, Schering shall pay Sequus within ten (10)
days of Board of Directors Approval, in partial consideration of the
distribution rights granted to Schering pursuant to this Agreement and in
recognition of the marketing authorization approval for the Agreement Product in
the EEA, Five Million Three Hundred Thousand Dollars ($5,300,000), **.

         7.9 Event and Criteria Attainment. Schering shall make ** payments upon
the completion of certain events and attaining certain criteria, in the party's
mutual reasonable judgment, and in consideration of Sequus' share of efforts in
that regard, totalling up to Twenty-Seven Million Dollars ($27,000,000), as
follows:

                  (a) ** 



                                       49
<PAGE>   55

**

                  (b) A total of up to ** for completion of the events and
meeting the criteria set forth on Schedule E, **

                  (c) **


                                       50
<PAGE>   56

                  (d) It is contemplated that multiple events and criteria may
be met by single events or occurrences and without regard to a particular order.
Full payment for completion of an event or achievement of a particular criteria
shall be made regardless of the time at which the event is completed or the
criteria achieved. All such payments shall be paid within thirty (30) days of
completion or occurrence of the event or achievement of the criteria in
question.

         7.10 Withholding. If at any time during or after the Agreement, any
jurisdiction within the Territory requires that taxes be withheld from any
payment (or portion thereof) of Sequus' compensation under this Agreement,
Schering may deduct such amount from the corresponding payment, or, if
applicable, Sequus will promptly reimburse Schering or its designee(s) such
amounts. Schering shall provide Sequus with documentation of such withholding
and payment in a manner that is satisfactory for purposes of the U.S. Internal
Revenue Service. Any withholdings paid when due hereunder shall be for the
account of Sequus and shall not be included in the calculation of Net Sales.
Sequus shall be liable for any deficiency, and any fine, assessment or


                                       51
<PAGE>   57

penalty imposed by any taxing authority in the Territory for any deficiency in
the amount of any such withholding or the failure to make such withholding
payment, unless such fine, assessment or penalty imposed was due to an act or
omission of Schering. If Schering is required to pay any such deficiency, or any
fine, assessment or penalty for any such deficiency for which Sequus is liable
above, Sequus shall promptly reimburse Schering for such payments, which shall
not be included in the calculation of Net Sales.

         7.11 Combination Products. Schering shall not distribute market or sell
Agreement Product as part of a combination product, i.e., sold in a package
containing other products, without the prior written approval of Sequus.

                                 VIII. INDEMNITY

         8.1 Indemnification by Schering.

                  (a) Schering shall indemnify, defend and hold harmless Sequus
and its Affiliates, and each of its and their respective employees, officers,
directors and agents (each, a "Sequus Indemnified Party") from and against any
and all liability, loss, damage, cost, and expense (including reasonable
attorneys' fees), subject to the limitations in Section 8.5 (collectively, a
"Liability") which the Sequus Indemnified Party may incur, suffer or be required
to pay resulting from or arising in connection with (i) the breach by Schering
of any covenant, representation or warranty contained in this Agreement, (ii)
any negligent act or omission or willful misconduct of Schering (or any
Affiliate thereof) in the development, promotion, manufacture, marketing or


                                       52
<PAGE>   58

sale of the Agreement Product or any other activity conducted by Schering under
this Agreement which is the proximate cause of injury, death or property damage
to a third party, (iii) the activities of Sequus and/or Schering associated with
the continued supply of Agreement Product as provided in Sections 8.8(a) or
8.8(c), (iv) the activities of Schering in the continued use of the Trademarks
as provided in Section 10.4, or (v) the successful enforcement by an Sequus
Indemnified Party of any of the foregoing.

                  (b) Schering also shall indemnify, defend and hold harmless
each Sequus Indemnified Party from and against any Liability which the Sequus
Indemnified Party may incur, suffer or be required to pay resulting from or
arising in connection with any negligent act or omission or willful misconduct
of Schering (or any Affiliate thereof) in the development, promotion,
manufacture, marketing or sale of the Agreement Product or any other activity
conducted by Schering under this Agreement after the termination of this
Agreement which is the proximate cause of injury, death or property damage to a
third party.

         8.2 Indemnification by Sequus.

                  (a) Sequus shall indemnify, defend and hold harmless Schering
and its Affiliates, and each of its and their respective employees, officers,
directors and agents (each, a "Schering Indemnified Party") from and against any
Liability which the Schering Indemnified Party may incur, suffer or be required
to pay resulting from or arising in connection with (i) the breach by Sequus of
any covenant, representation or warranty contained in this Agreement, (ii) any
negligent act or omission or willful


                                       53
<PAGE>   59

misconduct of Sequus (or any Affiliate thereof) in providing the Know-how or in
the development, promotion, manufacture, marketing or sale of the Agreement
Product or any other activity conducted by Sequus under this Agreement which is
the proximate cause of injury, death or property damage to a third party, or
(iii) the successful enforcement by an Schering Indemnified Party of any of the
foregoing.

                  (b) Sequus also shall indemnify, defend and hold harmless each
Schering Indemnified Party from and against any Liability which the Schering
Indemnified Party may incur, suffer or be required to pay resulting from or
arising in connection with any negligent act or omission or willful misconduct
of Sequus (or any Affiliate thereof) in the development, promotion, manufacture,
marketing or sale of the Agreement Product or any other activity conducted by
Sequus under this Agreement after the termination of the Agreement which is the
proximate cause of injury, death or property damage to a third party.

         8.3 Conditions to Indemnification. The obligations of the indemnifying
Party under Sections 8.1 and 8.2 are conditioned upon the delivery of written
notice to the indemnifying party of any potential Liability promptly after the
indemnified party becomes aware of such potential Liability. The indemnifying
party shall have the right to assume the defense of any suit or claim related to
the Liability if it has assumed responsibility for the suit or claim in writing;
however, if in the reasonable judgment of the indemnified party, such suit or
claim involves an issue or matter which could have a materially adverse effect
on the business operations or assets of the indemnified party, the


                                       54
<PAGE>   60

indemnified party may waive its rights to indemnity under this Agreement and
control the defense or settlement thereof, but in no event shall any such waiver
be construed as a waiver of any other indemnification rights such party may have
at law or in equity. If the indemnifying party defends the suit or claim, the
indemnified party may participate in (but not control) the defense thereof at
its sole cost and expense.

         8.4 Settlements. Neither party may settle a claim or action related to
a Liability without the consent of the other party, if such settlement would
impose any monetary obligation on the other party or require the other party to
submit to an injunction or otherwise limit the other party's rights under this
Agreement. Any payment made by a party to settle any such claim or action shall
be at its own cost and expense.

         8.5 Limitation of Liability. With respect to any claim by one party
against the other arising out of the performance or failure of performance of
the other party under this Agreement, the parties expressly agree that the
liability of such party to the other party for such breach shall be limited
under this Agreement or otherwise at law or equity to direct damages only and in
no event shall a party be liable for punitive, exemplary or consequential
damages.

         8.6 Insurance. Schering acknowledges that it maintains and shall,
during the term of this Agreement, maintain in full force and effect an
insurance program for liability insurance, including product liability and
contractual liability insurance, adequately covering it's obligations under this
Agreement. Sequus acknowledges that it maintains and shall, during the term


                                       55
<PAGE>   61

of this Agreement, maintain in full force and effect insurance coverage to
include products liability and contractual liability in the Territory in amounts
not less that **. Sequus shall provide thirty (30) days' prior written notice to
Schering in the event of cancellation or any material change in such insurance.
Each party shall provide the other party with evidence of such insurance
program, upon request.

         8.7 Third Party Intellectual Property. Sequus represents and warrants
that to the best of its knowledge the manufacture, use and sale of the Agreement
Product supplied to Schering under this Agreement ** in the Territory or in any
country where such Agreement Product is manufactured.

         8.8 Claimed Infringement

                  (a) Schering or Sequus, as the case may be, shall promptly
notify the other of any claim by a third party of infringement of such third
party's patent rights resulting from either Schering's or Sequus' undertakings
with respect to the Agreement Product hereunder, upon such claim of infringement
becoming known, directly or indirectly. In the event of any such notice,
Schering and Sequus agree to meet in good faith to determine their respective
courses of action with respect to the third party claim. Notwithstanding that,
Schering shall immediately discontinue any use, import, sale, distribution ** of
any Agreement Product upon notice from Sequus that in Sequus' reasonable
judgment such activity may be an infringement of such third party's patent
rights, and all liability arising out of Schering's use, sale, distribution **

Schering;


                                       56

Agreement Product, regardless of the fact of the third party claim, Schering
shall so notify Sequus, and Sequus shall continue to supply the Agreement
Product to Schering ** distribute and sell the Agreement Product. **

with its own counsel, at its sole discretion, control and expense. Schering
shall render reasonable assistance to Sequus in the defense of any such action
and shall be entitled to be represented by its own counsel at its sole expense.

                  (c) If Sequus seeks a license from such third party and is
unable to obtain such a license for Sequus and Schering to use, import, export,
sell, offer to sell, market, distribute ** Agreement Product in the
Territory under commercially reasonable terms, then, subject to Schering's right
to obtain a license on its own behalf, with any license terms to be subject to
Sequus' approval, not to be unreasonably withheld, Sequus may terminate this
Agreement upon immediate written notice to Schering; provided, however, that if
Schering desires to have a


                                       57
<PAGE>   63

continued supply of Agreement Product regardless of the fact of the third party
claim, Schering shall so notify Sequus and Sequus shall continue to supply the
Agreement Product to Schering. Schering shall, in accordance with Section
8.1(a), indemnify and hold Sequus harmless from any such claim of infringement,

shall be retained by Sequus for its sole benefit. If Sequus and Schering so
agree, Schering and Sequus may share the cost, equitably divided in relative
proportion to the balance of economic benefits intended by the Parties under
this Agreement, of any action against a third party infringer, and, in such
event, any award shall be applied first toward the recovery of each party's
costs, and any remaining amount of such award shall be shared by the parties in
the same proportion as the costs were shared.

         9.4 Unscheduled Modifications. Notwithstanding Section 9.3 above, if

Schering to comply with local law or regulations in connection with the
Agreement Product.

                          X. TRADEMARKS AND TRADE NAMES

         10.1 Trademark. Sequus shall be responsible for filing, prosecuting,
registering, maintaining and protecting the Trademarks in all countries of the
Territory, at is sole cost and expense. In the event that the Trademark cannot
be used pursuant to Section 10.4 or if it is agreed by the parties that a
different trademark is to be used other than or in addition to the Trademark in
any country of the Territory, then the parties shall agree on the trademark and
Sequus shall determine the availability and shall diligently file for and
prosecute said trademark, which shall thereafter be treated as a Trademark for
purposes of this Agreement. If the trademark is already owned by Schering, then
Schering shall assign all its rights, title and interest to said trademark to
Sequus, with Sequus to pay all costs related to the recordal of the assignment.
If the


                                       61
<PAGE>   67

trademark is to be purchased from a third party, then Sequus and Schering shall
agree on the allocation for acquiring said trademark.

         10.2 Trademark Use. Sequus hereby grants to Schering the exclusive
right to use the Trademarks in connection with Schering's sales of the Agreement
Product in the Territory, but only during the term of this Agreement and only so

accordance with the terms of this Agreement; provided, however, that Schering
shall be permitted to use the Trademark following termination of this Agreement
in connection with disposing of inventory of Agreement Product pursuant to
Section 12.9 below. Schering shall only use the Trademarks with the applicable
Agreement Product distributed, marketed or sold by Schering hereunder. Upon the
termination or expiration of this Agreement, Schering's right to use the
Trademarks shall automatically revert to Sequus.

         10.3 Trade Names. During the term of this Agreement and unless
prohibited by the responsible regulatory agency, Schering shall not use any
trademark other than the Trademarks (except for the name and logo of Schering or

in good faith to determine their respective courses of action with respect to
the third party claim. Notwithstanding that, Schering agrees to immediately
discontinue use of any Trademark upon notice from Sequus that such use is or may
be an infringement of such third party's trademark rights, except as provided
below, and all liability arising out of Schering's use of such trademark after
the date of such notice shall be borne by Schering. In the event of any such
third party notice, Schering and Sequus agree to meet in good faith to select a
new Sequus Trademark acceptable to both parties to be used with the Agreement
Product. If Schering desires to continue to sell Agreement Product using the
Trademark in question, Schering shall, in accordance with Section 8.1(a),
indemnify and hold Sequus harmless from any claim of infringement arising from
such continued sale by Schering.

         10.5 Third Party Infringement. Schering shall, upon Sequus' request,

third party of any Trademark as soon as practicable after becoming aware
thereof. The cost of any action against a third party infringer shall be borne
by Sequus, and any awards or judgments received by Sequus in any such actions

agree, Schering and Sequus may share the cost, equitably divided in relative
proportion to the balance of economic benefits intended by the parties under
this Agreement, of any action against a third party infringer, and, in such
event, any award shall be applied first toward the recovery of each party's
costs, and any remaining amount of such award shall be shared by the parties in
the same proportion as the costs were shared.

advertising and promotional material shall prominently feature the applicable
Trademark.

                                    disclosing party, (and such independent

                                    the receiving party), or

                                    party shall, prior to making any such
                                    disclosure, give the disclosing party
                                    sufficient advance written notice to permit
                                    the disclosing party to seek a protective
                                    order or other similar order with respect to

                                    with such law, rule or regulation, whether
                                    or not a protective order or other similar
                                    order is obtained.

         11.2 Return of Confidential Information. Upon termination of this
Agreement, if requested, the receiving party will return all documents, and
copies thereof, containing the disclosing party's Confidential Information at
any time upon request of the disclosing party. However, the receiving party may
retain one copy of such documents in a secure location solely for the purpose of
determining its obligations hereunder, to comply with any applicable regulatory
requirements, or to defend against any product liability claims. In the event
that any of the provisions of this Agreement relating to the disclosure or use
of Confidential Information conflict with any of the provisions of the letter of
intent dated July 8, 1996 and the May 13, 1994 Mutual Confidentiality Agreement
between the parties hereto, the provisions of this Agreement shall take
precedence and govern.

sell more than one hundred and ten percent (110%) of the prior six (6) months'
sales of Agreement Product on a country-by-country basis.

                       XX. SEVERABILITY AND ENFORCEABILITY

         20.1 Separability and Enforcement.

                  (a) Should any part or provision of this Agreement be held
unenforceable or in conflict with the applicable laws or regulations of any
jurisdiction, the invalid or unenforceable part or provision shall be replaced
with a provision which accomplishes, to the extent possible, the original

enforceable manner, and the remainder of this Agreement shall remain binding
upon the parties hereto.

                  (b) Nothing in this Agreement is intended to nor shall it have
the effect of excluding, modifying or restricting any right or remedy available
under any relevant law which, by virtue of any such law, cannot be excluded,
modified or restricted.

                                   XXI. EXPORT

         This Agreement is made subject to any restrictions concerning the
export of products or technical information from the United States of America
which may be imposed upon or related to Sequus or Schering from time to time by
the government of the United States of America. Furthermore, each party agree
that it will not export, directly or indirectly, any technical information or
products using such technical information to any country for which the United
States government or any agency thereof at the time of export requires an export
license or other governmental approval, without first obtaining the written
consent to do so from the Department of Commerce or other agency of the United
States government when required by an applicable statute or regulation. If at
any time there is a restriction on


                                       83
<PAGE>   89

export of Agreement Product that would materially affect Sequus' ability to

discuss the establishment of a second source of supply outside of the United
States.

                      XXII. REPRESENTATIONS AND WARRANTIES

or a third party is selling Agreement Product in the Territory or whereby Sequus
has authorized third parties to make, sell, distribute or supply the Agreement
Product in the Territory;

                  (e) **

                  (f) As of the Effective Date, it is not aware of any existing

<PAGE>   92

                  (a) In recognition of Sequus' obligations under the **
Agreement, Sequus shall have the right to sell to its third party distributor

reasonable judgment for sale for use


                                       87
<PAGE>   93

in the territory encompassed by the ** Agreement; provided, however, that Sequus
shall not sell the Agreement Product to any third party that could reasonably be
expected to resell the Agreement Product outside the territory encompassed by
the ** Agreement.

                  (b) Sequus shall provide to Schering a sales report on a

Sequus pursuant to the ** Agreement and the ** Agreement during the preceding
quarter.

                  (c) Sequus agrees to use reasonable business efforts to ensure
that Agreement Product sold to ** and ** are only sold in those countries
specified in their respective Agreements ("Sequus Distributor Territory"). In
the event that Schering demonstrates, or Sequus otherwise discovers, sales of
such product in countries outside the Sequus Distributor Territory, then Sequus
agrees to take all reasonable steps to prevent further such sales outside the
Sequus Distributor Territory. In the event that Sequus and/or Schering find
repeated, material sales of Agreement Product sold to ** or ** outside the
Sequus Distributor Territory, then Sequus will use such remedies available under
those Agreements, including but not limited to termination, to halt such sales.
Nothing herein shall cause Sequus to breach any provisions of the ** or **
Agreements.

                                   SCHEDULE C

                          Dispute Resolution Procedures

I.         Procedures for resolving disputes of the JDT:

           a. Within ten (10) business days after the receipt of the notice
           provided for in Section 3.4 of this Agreement, each party shall
           appoint an independent expert, knowledgeable in the field concerning
           the disputed matter (e.g., an expert in the field of developing
           pharmaceutical products for oncology indications), to serve on the
           special arbitration panel. The two independent experts so appointed
           by the parties, shall, within ten (10) business days thereafter,
           appoint a neutral third independent expert, knowledgeable in the
           field concerning the disputed matter. Such neutral third independent
           expert shall serve as the chairperson of the special arbitration
           panel. Each of the members of the special arbitration panel shall be
           required to sign a secrecy agreement with respect to any information
           provided by either party during the special arbitration procedure.

           b. Within five (5) business days after the chairperson of the special
           arbitration panel is appointed, each party shall submit, to each
           member of the special arbitration panel and to the other party, a
           written statement setting forth the relevant facts with respect to
           the disputed matter and arguments supporting such party's position
           with respect to the resolution of the disputed matter.

           c. Within five (5) business days after such written statements are
           provided to the special arbitration panel, the panel and appropriate
           representatives of each party shall meet so that the parties can
           present oral arguments to the arbitration panel and the arbitration
           panel can have the opportunity to ask questions of the parties. The
           location of such meeting shall be at Schering's facility in
           Kenilworth, New Jersey if Sequus requests the special arbitration and
           at Sequus' facility in Menlo Park, California if Schering requests
           the special arbitration. Each party shall have two (2) hours to
           present its arguments to the special arbitration panel and thirty
           (30) additional minutes to rebut the arguments made by the other
           party. The party requesting the special arbitration shall be the
           first to present its oral argument to the special arbitration panel.

           d. Within five (5) business days after such meeting, the special
           arbitration panel shall render a decision on the disputed matter,
           which decision shall be reduced to writing by the chairperson of the
           special arbitration panel and signed by each member of the special
           arbitration panel. The chairperson of the special arbitration panel
           shall be responsible for immediately providing a copy of the written


                                       -1-

<PAGE>   106
           decision to each party.  The decision of the special
           arbitration panel shall be binding upon the parties.

           e. Nothing contained herein shall be construed to permit the
           arbitration panel or any court or any other forum to award punitive,
           exemplary or any other damages. By entering into this Agreement to
           arbitrate, the parties expressly waive any claim for punitive,
           exemplary or any other damages with respect to the resolution of a
           deadlock by the JDT.

           f. Each party shall be responsible for its own costs incurred in such
           arbitration procedures and the cost of the special arbitration panel
           shall be shared equally by the parties.


II.        Procedures for resolving disputes other than disputes of
           the JDT:

           a. Except as otherwise set forth herein, any dispute, controversy or
           claim arising out of or relating to the validity, construction,
           enforceability or performance of this Agreement including disputes
           relating to an alleged breach or termination of this Agreement shall
           be settled by binding Alternative Dispute Resolution ("ADR") in the
           manner set forth below; provided, however, that the neutral referred
           to below shall give effect to the provisions of this Agreement and
           shall not adjust, modify or change the effects of termination as set
           forth in Article 11:

           b. If a party intends to begin an ADR to resolve a dispute, such
           party shall provide written notice (the "ADR Request") by certified
           or registered mail or properly documented overnight delivery to the
           other party informing such other party of such intention and the
           issues to be resolved. The notice shall explain the nature of the
           complaint and refer to the relevant sections of the Agreement upon
           which the complaint is based. The complaining party shall also set
           forth a proposed solution to the problem, including a suggested time
           frame within which the parties must act.

           c. The non-complaining party must respond in writing within
           forty-five (45) calendar days of receiving notice with an
           explanation, including references to the relevant provisions of the
           Agreement and a response to the proposed solution and suggested time
           frame for action. The non-complaining party may add additional
           issues to resolved.

           d. Within fifteen (15) business days of receipt of the response from
           the non-complaining party, the parties shall meet and discuss options
           for resolving the dispute. Each party shall make available all
           appropriate personnel to meet and confer with the other party within
           the fifteen


                                       -2-

<PAGE>   107
           (15) business day period following the complaining party's receipt of
           the response by the non-complaining party.

           e.   Any and all disputes that cannot be resolved pursuant to
           Paragraphs b, c and d above shall be submitted to a neutral who shall
           be selected by mutual agreement of the parties. If the parties are
           unable to agree upon a neutral, then the neutral shall be selected in
           accordance with the procedures of the American Arbitration
           Association. The neutral shall be an individual who shall preside
           over and resolve any disputes between the parties. The neutral
           selected shall be a former judge of a state or federal court and
           shall not be an employee, director or shareholder of, or otherwise
           have any current or previous relationship with, either party or its
           respective Affiliates. The ADR shall be conducted in accordance with
           the commercial arbitration rules of the American Arbitration
           Association Association then in effect, subject to the time periods
           and other provisions of this Schedule C, Part II or as otherwise set
           forth in this Agreement.

           f.   Consistent with the time schedule established pursuant to
           Paragraphs g and h above the neutral shall hold a hearing to resolve
           each of the issues identified by the parties and shall render a
           decision as expeditiously as possible but in no event more than
           thirty (30) calendar days after the close of hearings. In rendering
           the decision the neutral shall rule on each disputed issue and shall
           adopt in whole or in part the proposed ruling of one of the parties
           on each disputed issue.

           g.   During the meeting referred to in Paragraph d above, the parties
           shall negotiate in good faith the scope and schedule of discovery,
           relating to depositions, document production and other discovery
           devices, taking into account the nature of the dispute submitted for
           resolution. If the parties are unable to reach agreement as to the
           scope and schedule of discovery, the neutral may order such discovery
           as the neutral deems necessary. To the extent practicable taking into
           account the nature of the dispute submitted for resolution, such
           discovery shall be completed within sixty (60) calendar days from the
           date of the selection of the neutral. At the hearing, which shall
           commence within twenty (20) business days after completion of
           discovery unless the neutral otherwise orders, the parties may
           present testimony (either live witness or deposition), subject to
           cross-examination, and documentary evidence. To the extent
           practicable taking into account the nature of the dispute submitted
           for resolution and the availability of the neutral, the hearing shall
           be conducted over a period not to exceed thirty (30) consecutive
           business days, with each party entitled to approximately half of the
           allotted time unless otherwise ordered by the neutral. The hearing
           shall be held in or near Kenilworth, New Jersey if Sequus is the
           complaining party and in or near Menlo Park,


                                       -3-

           California if Schering is the complaining party or at such other
           place as may be agreed upon by the parties. The neutral shall have
           sole discretion with regard to the admissibility of any evidence and
           all other matters relating to the conduct of the hearing. The neutral
           shall, in rendering its decision, apply the substantive laws of the
           State of California (regardless of its or any other jurisdiction's
           choice of law principles). The decision of the neutral shall be final
           and not appealable, except in the case of fraud or bad faith on the
           part of the neutral or any party to the ADR proceeding in connection
           with the conduct of such proceedings.

           h. At least ten (10) business days prior to the date set for the
           hearing, each party shall submit to each other party and the neutral
           a list of all documents on which such party intends to rely in any
           oral or written presentation to the neutral and a list of all
           witnesses, if any, such party intends to call at such hearing and a
           brief summary of each witness' testimony. At least five (5) business
           days prior to the hearing, each party must submit to the neutral and
           serve on each other party a proposed findings of fact and conclusions
           of law on each issue to be resolved. Following the close of hearings,
           the parties shall each submit such post-hearing briefs to the neutral
           addressing the evidence and issues to be resolved as may be required
           or permitted by the neutral.

           i. Except as otherwise set forth herein, the neutral shall determine
           the proportion in which the parties shall pay the costs and fees of
           the ADR, and each party shall pay its own costs (including, without
           limitation, reasonable attorneys' fees) and expenses in connection
           with such ADR; provided, however, that if the neutral determines that
           the action of any party was arbitrary, frivolous or in bad faith, the
           neutral may award such costs and expenses to the prevailing party.

           j. The ADR proceeding shall be confidential and, except as required
           by law, neither party shall make (or instruct the neutral to make)
           any public announcement with respect to the proceedings or decision
           of the neutral without the prior written consent of the other party.
           The existence of any dispute submitted by ADR, and the award of the
           neutral, shall be kept in confidence by the parties and the neutral,
           except as required in connection with the enforcement of such award
           or as otherwise required by applicable law.

           k. For the purposes of this Schedule C, the parties acknowledge their
           diversity and agree to accept the jurisdiction of the Federal
           District Court in the States of California and New Jersey for the
           purposes of enforcing awards entered pursuant to this Schedule C,
           Part II and for enforcing the agreements reflected in this Schedule
           C, Part II.

<PAGE>   109
           l. Nothing contained herein shall be construed to permit the neutral
           or any court or any other forum to award punitive, exemplary or any
           similar damages. By entering into this Agreement to arbitrate, the
           parties expressly waive any claim for punitive, exemplary or any
           similar damages. The only damages recoverable under this Agreement
           are compensatory damages.

           m. The procedures specified in this Schedule C, Part II shall be the
           sole and exclusive procedures for the resolution of disputes between
           the parties which are expressly identified for resolution in
           accordance with this Schedule C, Part II.

                       ADVERSE EVENT REPORTING PROCEDURES


         The parties hereby agree that the following terms will govern
disclosures of each party to the other with respect to adverse event reporting
relating to the Agreement Product as clinically tested or marketed by or on
behalf of either party.

         1.      An Adverse Event ("AE") is defined as:

              a) any experience which is adverse, including what are commonly
described as adverse or undesirable experiences, adverse events, adverse
reactions, side effects, or death due to any cause associated with, or observed
in conjunction with the use of a drug, biological product, or device in humans,
whether or not considered related to the use of that product:

               - occurring in the course of the use of a drug,
                 biological product or device,

               - associated with, or observed in conjunction with
                 product overdose, whether accidental or intentional,

               - associated with, or observed in conjunction with
                 product abuse, and/or

               - associated with, or observed in conjunction with
                 product withdrawal.

              b) Any significant failure of expected
pharmacological or biologic therapeutical action (with the
exception of in clinical trials).

         2.      Serious or Non-Serious is defined as:

              a) A Serious AE is one that is life threatening or fatal,
permanently disabling, requires or prolongs in-patient hospitalization or
prolonged hospitalization, or is a congenital anomaly, cancer or overdose. In
addition, end organ toxicity, including hematological, renal, hepatic, and
central nervous system AEs, may be considered serious. In laboratory tests in
animals, a serious AE includes any experience suggesting significant risk for
human subjects.

               b) A Non-Serious AE is any AE which does not meet the
criteria for a serious AE.

         3.       Life-threatening is defined as: the patient is at
immediate risk of death from the AE as it occurs.


                                       -1-

<PAGE>   114
         4.       End-Organ Toxicity is defined as: A medically
significant event or lab value change in which a patient may not
necessarily be hospitalized or disabled, but is clinically
significant enough to warrant monitoring (e.g. seizures, blood
dyscrasias).

         5.       Expected or unexpected is defined as:

                  a) Expected AE - An AE which is listed in the Investigator's
Brochure for clinical trials, included in local labelling (e.g., Summary of
Agreement Product Characteristics) for Marketed Drugs, or in countries with no
local labelling, in the Corporate Standard Prescribing Document.

                  b) Unexpected AE - An AE that does not meet the criteria for
an expected AE or an AE which is listed but differs from that event in terms of
severity or specificity.

         6.       Associated with or related to the use of the drug is
defined as: A reasonable possibility exists that the AE was caused
by the drug.

         7.       Un-associated or unrelated to the use of the drug is
defined as:  A reasonable possibility exists that the AE may not
have been caused by the drug.

         8.       NDA Holder is defined as: An "Applicant" as defined in 21 CFR 
Part 314.3(b), for regulatory approval of an Agreement Product in any regulatory
jurisdiction, including a holder of a foreign equivalent thereto.

         9.       IND Holder is defined as: A "Sponsor" as defined in 21 CFR
Part 312.3(b) of an investigational new drug in any regulatory
jurisdiction, including a holder of a foreign equivalent thereto.

         10.      Capitalized terms not defined in this Exhibit shall have
the meaning assigned thereto in the Distribution Agreement (the
"Agreement").

         11.      With respect to the Agreement Product, the parties agree
as follows:

                  All initial reports and any follow-up information (oral or
                  written) for any and all Serious AEs as defined above, (other
                  than with respect to animal studies)which become known to
                  either party (other than from disclosure by or on behalf of
                  the other party) must be communicated by telephone, telefax or
                  electronically directly to the other party and/or the NDA
                  Holder, IND Holder (individually and collectively referred to
                  as "Holders") within forty eight hours of receipt of the
                  information. Written confirmation


                                       -2-

<PAGE>   115
                  of the Serious AE received by such party should be sent to the
                  other party and/or the Holders as soon as it becomes
                  available, but in any event within forty eight hours hours of
                  initial report of the Serious AE by such party.

                  Both parties shall exchange Medwatch and/or CIOMS forms and
                  other health authority reports within forty eight hours of
                  submission to any regulatory agency.

                  All initial reports and follow-up information received for all
                  Non-Serious AEs for marketed Agreement Product which become
                  known to a party (other than from disclosure by or on behalf
                  of the other party) must be communicated in writing, by
                  telefax or electronically to the other party on a monthly
                  basis, on Medwatch or CIOMs forms (where possible).

                  Each party shall coordinate and cooperate with the other
                  whenever practicable to prepare a single written report
                  regarding all Serious and/or Non-Serious AEs, provided,
                  however, that neither party shall be obligated to delay
                  reporting of any AE in violation of applicable law or
                  regulations regarding the reporting of adverse events.

         12.      The parties further agree that:

                  a) a written report be forwarded to the other party within
forty eight hours of receipt by the party making the report, for AEs
for animal studies which suggest a potential significant risk for
humans;

                  b) each party will give the other party a print-out or
computer disk of all AEs reported to it and its Affiliates relating to the
Agreement Product within the last year, within 30 days of receipt of a request

                  c) if either party wishes access to AE Reports of the other
party relating to the Agreement Product, upon request of that party, the other
party shall make available its AE records relating to the Agreement Product
(including computer disks) for viewing and copying by the other party. The
parties may discuss the transfer of AE Reports by computer disk.

                  d) disclosure of information hereunder by a party to the other
party shall continue as long as either party and/or its Affiliates or designeees
continue to clinically test or market Agreement Product.

                  e) all written regulatory reports, including periodic NDA,
annual IND, safety updates, or foreign equivalents thereto, etc.


                                       -3-

<PAGE>   116
shall be sent by a party to the other party within forty eight hours forty of
submission to the appropriate regulatory agency. The parties shall agree on a
procedure for preparing these reports.

         13. Each party shall diligently undertake the following further
obligations where both parties are or will be commercializing the Agreement
Product pursuant to the Agreement and/or performing clinical trials with respect
to the Agreement Product:

             a) upon the Effective Date, each party shall identify individuals
who shall be responsible for identifying all AE reporting requirements in all
countries of the Territory as set forth in the Agreement, and any amendments
