                           INSITE VISION INCORPORATED
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1996
                                   (UNAUDITED)


NOTE 1 - BASIS OF PRESENTATION

            The accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information and pursuant to the instructions to
Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments, consisting of normal recurring accrual adjustments, considered
necessary for a fair presentation have been included. Operating results for the
three month and six month periods ended June 30, 1996, are not necessarily
indicative of the results that may be expected for the year ended December 31,
1996.

            These financial statements and notes should be read in conjunction
with the Company's audited financial statements and notes thereto included in
the Company's Annual Report on Form 10-K for the year ended December 31, 1995.


NOTE 2 - PROPERTY AND EQUIPMENT

            In July 1996, the Company and Bausch & Lomb Incorporated (B&L)
announced a strategic alliance covering the manufacture of potential InSite
products, the worldwide marketing of InSite's PilaSite(R) product candidate for
glaucoma, and a joint development program utilizing InSite's proprietary drug
delivery technology. In connection with the alliance, B&L will make a $2.0
million equity investment in the Company, provide up to $2.0 million in new
product development funding, and pay royalties to InSite on future PilaSite(R)
product sales.

            As a result of the B&L alliance, the Company ended its relationship
with its previous contract manufacturer and wrote-off its share of equipment and
leasehold improvements installed at the previous supplier's plant. This resulted
in a non-cash charge to the Company's results of operations of $1.4 million
which is reported as a separate line item in the accompanying financial
statements. InSite's share of leasehold improvements at B&L facilities is
expected to be about $500,000.


NOTE 3 - STOCKHOLDERS' EQUITY

            In January 1996 the Company received net proceeds of approximately
$4.8 million from a private placement of 1,469,232 shares of its common stock
and 367,308 warrants. Each warrant entitles its holder to purchase one share of
the Company's common stock for $3.25 until January 2001. In April 1996, the
Company received net proceeds of approximately $7.9 million from a public
offering of 1,750,000 shares of its common stock. The Company also received
$654,000 from the exercise of options for 185,041 shares of its common stock in
January 1996.

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

            The following discussion should be read in conjunction with the
financial statements and notes thereto included in this Quarterly Report and in
the Company's Annual Report on Form 10-K for the year ended December 31, 1995.

            Except for the historical information contained herein, the
discussion in this Quarterly Report contains certain forward-looking statements
that involve risks and uncertainties, such as statements of the Company's plans,
objectives, expectations and intentions. The cautionary statements made in this
Quarterly Report should be read as being applicable to all related
forward-looking statements wherever they appear in this Quarterly Report. The
Company's actual results could differ materially from those discussed here.

OVERVIEW

            InSite Vision is developing ophthalmic pharmaceutical products based
on its proprietary DuraSite(R) eyedrop-based drug delivery technology, which is
designed to improve the safety, efficacy and medical value of existing
ophthalmic products and potentially permit the novel ophthalmic application of
drugs that are currently used or being developed for non-ophthalmic indications.
The DuraSite delivery system can be customized to deliver a wide variety of
potential drug candidates having a broad range of molecular weights and other
properties.

            To date, InSite Vision has not received any revenues from the sale
of products, although it has received an insignificant small amount of royalties
from the sale of products using the Company's licensed technology. The Company
has been unprofitable since its inception and expects to continue to incur
substantial losses for at least the next several years, due to continuing
research and development efforts, including preclinical studies, clinical trials
and manufacturing of its product candidates. The Company has financed its
research and development activities and operations primarily through private and
public placement of its equity securities and, to a lesser extent, from
collaborative agreements.

            In November 1995, InSite restructured its operations and reduced its
staff by approximately 50% to enable it to conserve its financial resources.
Self-funded product development was reduced substantially and the Company
discontinued plans to establish its own sales and marketing organization. The
Company is attempting, through corporate partnering and other potential business
opportunities, to recognize the value of its late-stage product candidates and
its drug delivery technology.

            In May 1996, InSite entered into an agreement with CIBA Vision
Ophthalmics (CIBA Vision) whereby InSite regained full U.S. marketing rights to
InSite's PilaSite(R), product candidate for glaucoma. In exchange, CIBA Vision
received royalty-bearing, co-exclusive U.S. marketing rights to InSite's
ToPreSiteTM product candidate for ocular inflammation/infection. CIBA Vision
assumed all subsequent product development, clinical and regulatory
responsibility for ToPreSiteTM. In addition, CIBA Vision received
royalty-bearing, co-exclusive U.S. marketing rights to InSite Vision's ISV-205
product candidate for certain non-glaucoma-related indications.

            During July 1996, the Company entered into agreements with Bausch &
Lomb Incorporated (B&L) which provide for:

            B&L to manufacture InSite product candidates at B&L's facility in
            Tampa, Florida using equipment owned by InSite, and for B&L and
            InSite to share the cost of certain leasehold improvements in
            connection with the installation and operation of the equipment;


                                     7 of 17
<PAGE>   8
            B&L to receive, for a fee of $500,000, an exclusive worldwide
            royalty-bearing license to manufacture and market PilaSite(R);

            A collaboration between the Company and B&L to develop and sell a
            new DuraSite(R) based eyedrop formulation; and

            A $2 million equity investment by B&L in the Company.

            As a result of these agreements, the Company has elected to vacate
            its co-tenancy of a clean room at another supplier's plant and in
            June 1996 wrote-off the amounts it had previously capitalized
            related to that facility. This write-off resulted in a non-cash
            charge to the Company's results of operations of $1.4 million which
            is reported as a separate line item in the accompanying financial
            statements.

            As of June 30, 1996, the Company's accumulated deficit was
approximately $62.3 million. There can be no assurance that InSite Vision will
achieve either significant revenues from product sales or profitable operations.

RESULTS OF OPERATIONS

            The Company earned royalty income of $12,000 and $26,000 for the
quarters ended June 30, 1996 and 1995, respectively, from sales of AquaSite(R)
by CIBA Vision. To date, the Company has not relied on royalty revenues for
funding its activities, nor has it received revenues from the sale of products.
The Company does not expect to receive significant product revenue or royalties
for several years, if at all.

            Research and development expenses declined 35% in the second quarter
of 1996 to $1.4 million from $2.1 million in the second quarter of 1995 with a
40% decline to $2.8 million from $4.6 million during the six months ended June
30, 1996 and 1995, respectively. The decreases are primarily due to lower
expenditures for human clinical studies of the Company's product candidates. As
part of the restructuring described above, the Company has deferred significant
additional expenditures by delaying the filing of new drug applications with the
U.S. Food and Drug Administration for its BetaSite(R) and PilaSite(R) product
candidates to treat glaucoma. As a result, it is presently anticipated that
research and development expenses will be lower in 1996 than in 1995.

            The Company has re-prioritized its earlier stage development
activities, placing emphasis on the ongoing Phase II study of its product
ISV-120 for prevention of pterygium recurrence and on the initiation of clinical
studies using ISV-205 for the prevention of steroid-induced glaucoma. Later
stage product development is expected to be conducted through corporate
partnering arrangements, if available and if with acceptable terms.

            General and administrative expenses declined 31% during the quarter
ended June 30, 1996 to $812,000 from $1.2 million during the second quarter of
1995, with a 38% decline to $1.5 million from $2.4 million during the six months
ended June 30, 1996 and 1995, respectively. The Company did not replace the
general and administrative employees who voluntarily left the Company during
1995 and, in November 1995, announced that it would not establish its own sales
and marketing organization and that it had made additional staff reductions in
its administration and manufacturing areas. As a result, general and
administrative expenses are expected to be lower in 1996 than in 1995.


                                     8 of 17
<PAGE>   9
            Interest and other income were $143,000 and $140,000 for the
quarters ended June 30, 1996 and 1995, respectively. Interest earned in the
future will be dependent on the Company's funding cycles and prevailing interest
rates. Interest expense relates primarily to notes payable.

            The Company incurred net losses of $3.5 million and $3.2 million for
the three month periods ended June 30, 1996 and 1995, respectively, resulting in
net losses of $5.5 million and $6.7 million for the first six months of 1996 and
1995, respectively. The Company expects to incur substantial additional losses
over the next several years. The losses are expected to fluctuate from period to
period based primarily on the level of clinical activities.

LIQUIDITY AND CAPITAL RESOURCES

            InSite Vision has financed its operations primarily through private
placements of preferred stock totaling $32.0 million, an October 1993 public
offering of common stock which resulted in net proceeds of approximately $30.0
million, a January 1996 private placement of common stock and warrants which
raised net $4.8 million and an April 1996 public offering which raised net $7.9
million. At June 30, 1996, the Company had cash and equivalents totaling $12.7
million. It is the Company's policy to invest these funds in highly liquid
securities, such as time deposits, interest bearing money market funds,
commercial paper, Treasury and federal agency notes and corporate debt.

            For the six months ended June 30, 1996 and 1995, expenditures for
operating activities and additions to capital equipment were $4.5 million and
$7.5 million, respectively. Of those amounts, $63,000 and $1,232,000 were for
additions to laboratory and other property and equipment in 1996 and 1995,
respectively. The Company expects to expend approximately $500,000 during the
second half of 1996 as its share of leasehold improvements at B&L's facilities
in Tampa, Florida. The timing of future expenditures will correspond to the
timing of clinical trials of potential products and additional product
development.

            The Company's future capital uses and requirements will depend on
numerous factors, including the progress of its research and development
programs, the progress of preclinical and clinical testing, the time and costs
involved in obtaining regulatory approvals, the cost of filing, prosecuting,
defending and enforcing patent claims and other intellectual property rights,
competing technological and market developments, changes in the Company's
existing collaborative and licensing relationships, the ability of the Company
to establish additional collaborative arrangements, acquisition of new products
and technologies, the completion of commercialization activities and
arrangements, and the purchase of additional plant and equipment.

            The Company anticipates no material capital expenditures to be
incurred for environmental compliance in fiscal year 1996. Based on the
Company's good environmental compliance record to date and its current
compliance with applicable environmental laws and regulations, environmental
compliance is not expected to have a material adverse effect on the Company's
operations.

            The Company believes that its cash and equivalents will be
sufficient to meet its operating expenses and cash requirements through 1997.
The Company expects to incur substantial additional development costs prior to
reaching profitability. As a result, InSite Vision will require substantial
additional funds and the Company may seek research funding, private or public
equity investments, and possible future collaborative agreements to meet such
needs. Even if the Company does not have an immediate need for additional cash,
it may seek access to the public equity markets if and when conditions are
favorable. There is no assurance that such additional funds will be available
for the Company to finance its operations on acceptable terms, if at all.

EARLY STAGE OF DEVELOPMENT; TECHNOLOGICAL UNCERTAINTY

            InSite is at an early stage of development. Only one product
utilizing the Company's DuraSite technology, an over-the-counter ("OTC") dry eye
treatment, is currently being marketed. Most of the potential products currently
under development by the Company will require significant additional research
and development, and preclinical and clinical testing, prior to submission to
regulatory authorities for marketing approval. The Company's potential products
are subject to the risks of failure inherent in the development of products
based on new technologies. These risks include the possibilities that the
Company's technology or any or all of its potential products will be found to be
unsafe, ineffective, or otherwise fail to receive necessary marketing clearance;
that the potential products, if safe and effective, will be difficult to
manufacture or market; that proprietary rights of third parties will preclude
the Company from marketing products; or that third parties will market superior,
equivalent or more cost-effective products. As a result, there can be no
assurance that the Company's research and development activities will result in
any commercially viable products.

FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING

            The Company will require substantial additional funds to conduct the
development and testing of its potential products and to manufacture and market
any products that may be developed. As described in Management's Discussion and
Analysis, the Company's future capital requirements will depend on numerous
factors, including the progress of its research and development programs, the
progress of preclinical and clinical testing, the time and costs involved in
obtaining regulatory approvals, the cost of filing, prosecuting, defending and
enforcing patent claims and other intellectual property rights, competing
technological and market developments, changes in the Company's existing
collaborative and licensing relationships, the ability of the Company to
establish corporate partnerships for the manufacture and marketing of its
potential products, and the purchase of additional capital equipment. The
Company intends to seek additional funding through public or private financings,
collaborative or other arrangements, or from other sources. There can be no
assurance that additional financing will be available from any of these sources
or, if available, that it will be available on acceptable terms. If additional
funds are raised by issuing equity securities, significant dilution to existing
stockholders may result. If adequate funds are not otherwise available, the
Company may be required to delay, scale back or eliminate one or more of its
research, discovery or development programs, or to obtain funds through entering
into arrangements with collaborators or others that may require the Company to
relinquish rights to certain of its technologies, product candidates or
products, or to cease operations.

HISTORY OF OPERATING LOSSES; UNCERTAINTY OF FUTURE FINANCIAL RESULTS

            The Company has incurred significant operating losses since its
inception in 1986 and it expects to continue to incur significant operating
losses for at least the next several years. The amount of net losses and the
time required by the Company to reach profitability are uncertain. The Company's
ability to achieve profitability depends upon its ability, alone or with others,
to complete successful development of its potential products, conduct clinical
trials, obtain required regulatory approvals and successfully manufacture and
market its products. There can be no assurance that the Company will ever
achieve significant revenue or achieve profitability on a sustained basis.

DEPENDENCE ON THIRD PARTIES

            In connection with its restructuring in November 1995, the Company
elected not to proceed with plans to establish a dedicated sales and marketing
organization. In order to successfully commercialize its product candidates, the
Company will be required to enter into arrangements with


                                    10 of 17
<PAGE>   11
one or more companies that will: provide for Phase III clinical testing,
commercial scale-up and manufacture of the Company's potential products; obtain
or assist the Company in other activities associated with obtaining regulatory
approvals for its product candidates; and market and sell the Company's
products, if approved.

            To date, the Company has entered into agreements with CIBA Vision
for co-exclusive rights with the Company in the United States to manufacture and
market AquaSite, MethaSite(R), ToPreSite and ISV-205 for certain
non-glaucoma-related indications. Of these, only AquaSite, an OTC product for
which regulatory approval is not required, has been marketed. In an agreement
entered into with CIBA Vision in May 1996, the Company regained full U.S.
marketing rights to the Company's PilaSite product candidate for glaucoma. In
exchange, CIBA Vision received royalty-bearing, co-exclusive U.S. marketing
rights to ToPreSite product candidate for ocular inflammation/infection. CIBA
Vision assumed all subsequent product development, clinical and regulatory
responsibility for ToPreSite. In addition, CIBA Vision received royalty-bearing,
co-exclusive U.S. marketing rights to the Company's ISV-205 product candidate
for certain non-glaucoma-related indications. CIBA Vision has no obligation to
fund the further development of MethaSite or ISV-205.

            In July 1996 the Company entered into agreements with Bausch & Lomb
Incorporated (B&L) which provide for: B&L to receive an exclusive worldwide
royalty bearing license to manufacture and market PilaSite; a collaboration
between the two parties to develop and sell a new formulation of DuraSite; and
the Company to move its manufacturing equipment to B&L facilities in Tampa,
Florida and to share with B&L the cost of building a new clean room.

            There can be no assurance that, even if regulatory approvals are
obtained, products will be successfully marketed, or that the Company will be
able to conclude arrangements with other companies to support the
commercialization of such products on acceptable terms, if at all.

            The Company's strategy for research, development and
commercialization of certain of its products requires the Company to enter into
various arrangements with corporate and academic collaborators, licensors,
licensees and others, and is dependent on the subsequent success of these
outside parties in performing their responsibilities. For example, the Company
is dependent upon British Biotechnology plc ("British Biotech") for the supply
of batimastat and lexipafant, the active drugs incorporated into the Company's
ISV-120 and ISV-611 product candidates, respectively. British Biotech is
currently conducting clinical testing of batimastat and lexipafant for
non-ophthalmic indications. Should British Biotech elect not to proceed with the
development of either product candidate, the Company may have no source of
ongoing raw materials for affected product candidates and its business may be
adversely affected. In addition, there can be no assurance that the Company's
collaborators will not take the position that they are free to compete using the
Company's technology without accounting to the Company, or will not pursue
alternative technologies or develop alternative products either on their own or
in collaboration with others, including the Company's competitors, as a means
for developing treatments for the disease or disorders targeted by these
collaborative programs.

UNCERTAINTY OF PATENTS AND PROPRIETARY RIGHTS

            The Company's success will depend in large part on its ability to
obtain patents, protect trade secrets and operate without infringing upon the
proprietary rights of others. A substantial number of patents in the field of
ophthalmology have been issued to pharmaceutical, biotechnology and
biopharmaceutical companies. Moreover, competitors may have filed patent
applications, may have been issued patents or may obtain additional patents and
proprietary rights relating to products or processes competitive with those of
the Company. There can be no assurance that the Company's patent applications
will be approved, that the Company will develop additional proprietary products
that


                                    11 of 17
<PAGE>   12
are patentable, that any issued patents will provide the Company with adequate
protection for its inventions or will not be challenged by others, or that the
patents of others will not impair the ability of the Company to commercialize
its products. The patent position of firms in the pharmaceutical industry
generally is highly uncertain, involves complex legal and factual questions, and
has recently been the subject of much litigation. No consistent policy has
emerged from the U.S. Patent and Trademark Office or the courts regarding the
breadth of claims allowed or the degree of protection afforded under
pharmaceutical patents. There can be no assurance that others will not
independently develop similar products, duplicate any of the Company's products
or design around any patents of the Company.

            A number of pharmaceutical companies and research and academic
institutions have developed technologies, filed patent applications or received
patents on various technologies that may be related to the Company's business.
Some of these technologies, applications or patents may conflict with the
Company's technologies or patent applications. Such conflict could limit the
scope of the patents, if any, that the Company may be able to obtain or result
in the denial of the Company's patent applications. In addition, if patents that
cover the Company's activities have been or are issued to other companies, there
can be no assurance that the Company would be able to obtain licenses to these
patents, at all, or at a reasonable cost, or be able to develop or obtain
alternative technology. If the Company does not obtain such licenses, it could
encounter delays or be precluded from introducing products to the market.
Litigation may be necessary to defend against or assert claims of infringement,
to enforce patents issued to the Company or to protect trade secrets or know-how
owned by the Company, and could result in substantial cost to and diversion of
effort by, and may have a material adverse effect on, the Company. In addition,
there can be no assurance that these efforts by the Company will be successful.

            The Company's competitive position is also dependent upon unpatented
trade secrets. There can be no assurance that others will not independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to the Company's trade secrets, that such trade secrets
will not be disclosed or that the Company can effectively protect its rights to
unpatented trade secrets. To the extent that the Company or its consultants or
research collaborators use intellectual property owned by others in their work
for the Company, disputes also may arise as to the rights in related or
resulting know-how and inventions.

NO COMMERCIAL MANUFACTURING EXPERIENCE

            The Company has no experience in the manufacture of products for
commercial purposes. The Company has a pilot facility licensed by the State of
California to manufacture certain of its products for Phase I and Phase II
clinical trials. Contract manufacturers must adhere to regulations enforced by
the United States Food and Drug Administration ("FDA") on an ongoing basis
through its facilities inspection program. There are a limited number of Good
Manufacturing Processes contract manufacturers which are able to manufacture
products using InSite's technology. In July 1996, the Company entered into an
alliance under which B&L has agreed to manufacture Company products. If the
Company should encounter delays or difficulties in establishing and maintaining
its relationship with B&L or other qualified manufacturers to produce, package
and distribute its finished products, then clinical trials, regulatory filings,
market introduction and subsequent sales of such products would be adversely
affected.

            Contract manufacturing facilities must pass a pre-approval plant
inspection before the FDA will approve a new drug application ("NDA"). There can
be no assurance that the FDA or other regulatory agencies will approve the
process or the facilities by which any of the Company's products may be
manufactured. The Company's dependence on third parties for the manufacture of
products may adversely affect the Company's ability to develop and deliver
products on a timely and competitive


                                    12 of 17
<PAGE>   13
basis. Should the Company be required to manufacture products itself, the
Company will be subject to the regulatory requirements described above, to
similar risks regarding delays or difficulties encountered in manufacturing any
such products and will require substantial additional capital. There can be no
assurance that the Company will be able to manufacture any such products
successfully or in a cost-effective manner. In addition, certain of the raw
materials the Company uses in formulating its DuraSite drug delivery system are
available from only one source. Any significant interruption in the supply of
these raw materials could delay the Company's clinical trials, product
development or product sales and could have a material adverse effect on the
Company's business.

GOVERNMENT REGULATION AND PRODUCT APPROVAL

            FDA and comparable agencies in state and local jurisdictions and in
foreign countries impose substantial requirements upon preclinical and clinical
testing, manufacturing and marketing of pharmaceutical products. Lengthy and
detailed preclinical and clinical testing, validation of manufacturing and
quality control processes, and other costly and time-consuming procedures are
required. Satisfaction of these requirements typically takes several years and
the time needed to satisfy them may vary substantially, based on the type,
complexity and novelty of the pharmaceutical product. The effect of government
regulation may be to delay or to prevent marketing of potential products for a
considerable period of time and to impose costly procedures upon the Company's
activities. There can be no assurance that the FDA or any other regulatory
agency will grant approval for any products developed by the Company on a timely
basis, or at all. Success in preclinical or early stage clinical trials does not
assure success in later stage clinical trials. Data obtained from preclinical
and clinical activities are susceptible to varying interpretations which could
delay, limit or prevent regulatory approval. If regulatory approval of a product
is granted, such approval may impose limitations on the indicated uses for which
a product may be marketed. Further, even if regulatory approval is obtained,
later discovery of previously unknown problems with a product may result in
restrictions on the product, including withdrawal of the product from the
market. Delay in obtaining or failure to obtain regulatory approvals would have
a material adverse effect on the Company's business.

            The FDA's policies may change and additional government regulations
may be promulgated which could prevent or delay regulatory approval of the
Company's potential products. Moreover, increased attention to the containment
of health care costs in the United States could result in new government
regulations which could have a material adverse effect on the Company's
business. The Company is unable to predict the likelihood of adverse
governmental regulation which might arise from future legislative or
administrative action, either in the United States or abroad. See "- Uncertainty
of Product Pricing, Reimbursement and Related Matters."

COMPETITION

            The Company's success depends upon developing and maintaining a
competitive position in the development of products and technologies in its
areas of focus. There are many competitors of the Company in the United States
and abroad, including pharmaceutical, biotechnology and other companies with
varying resources and degrees of concentration on the ophthalmic pharmaceuticals
market. The Company's competitors may have existing products or products under
development which may be technically superior to those of the Company or which
may be less costly or more acceptable to the market. Competition from such
companies is intense and expected to increase as new products enter the market
and new technologies become available. The Company's competitors, many of whom
have substantially greater financial, technical, marketing and human resources
than the Company, may also succeed in developing technologies and products that
are more effective, safer or more commercially acceptable than any which have
been or are being developed by the Company. The Company's competitors may obtain
cost advantages, patent protection or other intellectual property rights that


                                    13 of 17

would block or limit the Company's ability to develop its potential products, or
may obtain regulatory approval for the commercialization of their products more
effectively or rapidly than the Company. To the extent that the Company
determines to manufacture and market its products by itself, it will also
compete with respect to manufacturing efficiency and marketing capabilities,
areas in which it has limited or no experience.

MARKETING AND SALES

            The Company plans to market and sell its products through
arrangements with one or more pharmaceutical companies with expertise in the
ophthalmic drug industry. There can be no assurance that the Company will be
able to enter into such arrangements on acceptable terms, if at all. If the
Company is not successful in concluding such arrangements, it may be required to
establish its own sales and marketing organization, although the Company has no
experience in sales, marketing or distribution. There can be no assurance that
the Company will be able to build such a marketing staff or sales force, or that
the Company's sales and marketing efforts will be cost-effective or successful.
To the extent the Company has entered into or enters into co-marketing,
co-promotion or other licensing arrangements for the marketing and sale of its
products, any revenues received by the Company will be dependent on the efforts
of third parties (such as CIBA Vision and B&L), and there can be no assurance
that such efforts will be successful.

DEPENDENCE ON KEY PERSONNEL

            The Company is highly dependent on Dr. Chandrasekaran and other
principal members of its scientific and management staff, the loss of whose
services might significantly delay the achievement of planned development
objectives. Furthermore, recruiting and retaining qualified personnel will be
critical to the Company's success. There can be no assurance that the Company
will be able to continue to attract and retain such personnel necessary for the
development of the Company's business.

PRODUCT LIABILITY EXPOSURE; LIMITED INSURANCE COVERAGE

            The Company's business exposes it to potential product liability
risks which are inherent in the testing, manufacturing, marketing and sale of
human therapeutic products. Product liability insurance for the pharmaceutical
industry generally is expensive. There can be no assurance that the Company's
present product liability insurance coverage is adequate. Such existing coverage
will not be adequate as the Company further develops its products, and no
assurance can be given that adequate insurance coverage against potential claims
will be available in sufficient amounts or at a reasonable cost.

UNCERTAINTY OF PRODUCT PRICING, REIMBURSEMENT AND RELATED MATTERS

            The Company's business may be materially adversely affected by the
continuing efforts of governmental and third party payers to contain or reduce
the costs of health care through various means. For example, in certain foreign
markets the pricing or profitability of health care products is subject to
government control. In the United States, there have been, and the Company
expects there will continue to be, a number of federal and state proposals to
implement similar government control. While the Company cannot predict whether
any such legislative or regulatory proposals or reforms will be adopted, the
announcement of such proposals or reforms could have a material adverse effect
on the Company's ability to raise capital or form collaborations, and the
adoption of such proposals or reforms could have a material adverse effect on
the Company.


                                    14 of 17
<PAGE>   15
            In addition, in both the United States and elsewhere, sales of
health care products are dependent in part on the availability of reimbursement
from third party payers, such as government and private insurance plans.
Significant uncertainty exists as to the reimbursement status of newly approved
health care products, and third party payers are increasingly challenging the
prices charged for medical products and services. If the Company succeeds in
bringing one or more products to the market, there can be no assurance that
reimbursement from third party payers will be available or will be sufficient to
allow the Company to sell its products on a competitive basis.

HAZARDOUS MATERIALS; ENVIRONMENTAL MATTERS

            The Company's research, development and manufacturing processes
involve the controlled use of small amounts of hazardous and radioactive
materials. The Company is subject to federal, state and local laws and
regulations governing the use, manufacture, storage, handling and disposal of
such materials and certain waste products. Although the Company believes that
its safety procedures for handling and disposing of such materials comply with
the standards prescribed by such laws and regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. In
the event of such an accident, the Company could be held liable for any damages
that result, and any such liability could exceed the resources of the Company.
Moreover, the Company may be required to incur significant costs to comply with
environmental laws and regulations, especially to the extent that the Company
determines to manufacture its own products.

CONTROL BY MANAGEMENT AND EXISTING STOCKHOLDERS

            As of June 30, 1996, the Company's management and principal
stockholders in the aggregate owned beneficially approximately 32.2% of the
Company's outstanding shares of Common Stock. As a result, these stockholders,
acting together, would be able to effectively control most matters requiring
approval by the stockholders of the Company, including the election of a
majority of the directors.

VOLATILITY OF STOCK PRICE; NO DIVIDENDS

            The market prices for securities of biopharmaceutical and
biotechnology companies (including the Company) have historically been highly
volatile, and the market has from time to time experienced significant price and
volume fluctuations that are unrelated to the operating performance of
particular companies. Future announcements concerning the Company, its
competitors or other biopharmaceutical companies including the results of
testing and clinical trials, technological innovations or new therapeutic
products, governmental regulation, developments in patent or other proprietary
rights, litigation or public concern as to the safety of products developed by
the Company or others and general market conditions may have a significant
effect on the market price of the Common Stock. The Company has not paid any
cash dividends on its Common Stock and does not anticipate paying any dividends
in the foreseeable future.

ANTI-TAKEOVER PROVISIONS

            The ability of the Board of Directors of the Company to issue shares
of Preferred Stock without stockholder approval may have certain anti-takeover
effects. The Company also is subject to provisions of the Delaware General
Corporation Law which may make certain business combinations more difficult.

<PAGE>   4
                  thereof, InSite hereby grants to CVO during the Agreement
                  Period an exclusive license subject to all the terms and
                  conditions of this Agreement and to Section 2.4 hereof with

            2.3   InSite hereby reserves for itself (i) all rights under the

                  clause (ii) above of this Section 2.3 shall not in any way be
                  assigned or transferred to any third party; provided however
                  that such rights may be assigned without CVO's consent in a
                  merger, reorganization or sale of all or substantially all of
                  InSite's assets or a transaction whereby control of InSite
                  changes to InSite's successor in interest in such transaction;
                  provided further that, upon the occurrence of any such
                  transaction, if InSite is not then marketing such product,
                  then InSite or its successor in interest shall not have the
                  right to sell the SAC Product or Other Products in the
                  Territory until the end of 36 months following the date of the
                  CVO's first commercial sale of the applicable Product in the
                  Territory (or, if there has been no commercial sale of the
                  applicable Product in the Territory during the first year
                  following the date of any FDA or similar registration for sale
                  of such Product in such country in the Territory ("Product
                  Approval"), then 48 months after Product Approval).

            2.4   In the event CVO elects not to commercialize the SAC Product
                  or Other Product, then upon ninety (90) days prior written
                  notice from InSite, the exclusive right and license granted to
                  CVO under Sections 2.1 and 2.2 with respect to such SAC
                  Product and/or Other Product shall terminate and shall revert
                  to InSite, provided that such rights shall not be assigned or
                  transferred to any third party, whether by way of license,
                  merger, reorganization or sale of all or substantially all of
                  InSite's assets, for a period of 24 months following CVO's
                  election not to pursue commercialization or to cease marketing
                  such Product. Following such 24 month period, Insite may
                  assign or transfer such rights without CVO's consent. In the
                  event that CVO has not (i) initiated clinical studies of at
                  least one SAC Product or Other Product within three (3) years
                  after the Effective Date; or (ii) filed for FDA approval for
                  such SAC Product or Other Product within four (4) years after
                  initiation of clinical trials of such product, or (iii)
                  commercialized such SAC Product or Other Product within one
                  (1) year after FDA approval therefor whether such approval was
                  obtained by CVO or by InSite (if InSite thereafter transferred
                  commercialization to CVO) and CVO is marketing a product
                  competitive with either the SAC 


                                       4
<PAGE>   5
                  Product or Other Product, then CVO's exclusive right and
                  license under Sections 2.1 and 2.2 with respect to such SAC
                  Product and/or Other Product shall immediately terminate and
                  revert to InSite, unless CVO can in good faith show that its
                  inability to meet the foregoing timelines was beyond its
                  reasonable control. CVO shall be deemed to have elected not to
                  commercialize the SAC Product or Other Product if CVO fails to
                  use such level of efforts, in accordance with CVO's business,
                  legal, medical and scientific judgment and CVO's normal
                  practices and procedures, to continue the development of the
                  SAC Product or Other Product pursuant to this Agreement
                  through pre-clinical and clinical studies and other
                  registration directed activities with the FDA or other
                  corresponding federal or state government agencies.

            2.5   Unless this Agreement is terminated for cause by InSite under
                  Section 17.2 or by CVO under Section 17.3, at the end of the
                  Agreement Period, CVO shall have the unrestricted perpetual
                  right to practice the Know-How free of charge, to manufacture,
                  have manufactured and use such Agreement Product anywhere in
                  the world and to sell such Agreement Product in the Territory.

         3. DEVELOPMENT

            3.1   InSite shall use commercially reasonable efforts to conduct
                  the development work for the Products. It is understood by the
                  parties that the formulations of the SAC Product, the Other
                  Products and the Glaucoma Product may be identical, or there
                  may be different formulations for the different Products.

            3.2   In the event InSite elects not to complete the initial
                  development of either the SAC Product or any of the Other
                  Products, CVO shall be entitled to proceed with the
                  development of such Product(s) as InSite has abandoned and
                  InSite will make available, subject to the terms of the
                  license granted in Section 2.2 above, to CVO at the time of
                  InSite's election, all of its Know-How relating only to the
                  development of the Product(s) that InSite elects not to
                  proceed with. CVO shall have the right to reference relevant
                  data in InSite submissions on the Glaucoma Product in order to
                  conduct the development of the SAC or Other Products. InSite
                  shall make such election within one year of the Effective
                  Date. InSite shall be deemed to have elected not to complete
                  development of the SAC Product or any of the Other Product if
                  InSite fails to use such level of efforts, in accordance with
                  InSite's business, legal, medical and scientific judgment and
                  InSite's normal practices and procedures, to continue the
                  development of such SAC Product or such Other Product pursuant
                  to this Agreement through pre-clinical and clinical studies
                  and other registration directed activities with the FDA or
                  other corresponding federal or state government agencies.

            3.3   With respect to its submissions to the FDA for any of the
                  Products, InSite shall 



                                       5
<PAGE>   6
                  be entitled, but not obligated, to reference the CVO Data. In
                  Data. In the event InSite elects to reference CVO Data, CVO
                  will cooperate and provide any and all documentation necessary
                  to permit InSite to reference and include such data in its own
                  filings.

            3.4   Each party will, upon request, make available to the other,
                  under a secrecy agreement, such know-how relating to such
                  party's Novel Preservative systems as shall be necessary to
                  allow the requesting party to incorporate such Novel
                  Preservative for use in the Products.

         4. ROYALTIES

            4.1   In consideration of the rights granted in Section 2 hereof,
                  CVO shall pay InSite the royalties set forth in this Section 
                  4. In consideration of, and in the event InSite exercises, the
                  right to reference CVO Data set forth in Section 3.3 hereof,
                  InSite shall pay CVO the royalties set forth in this Section 
                  4.

            4.2   In the event InSite completes the development of the SAC
                  Product or Other Product using a different formulation than
                  the Glaucoma Product, and obtains approval for the NDA
                  therefor, CVO shall pay InSite a royalty * * * of CVO Net
                  Sales of the applicable Product until the later to occur (i)
                  ten (10) years after the date of first commercial sale of such
                  Product; or (ii) until the expiration of the last to expire
                  patent in the Patent Rights ("CVO Royalty Period").
                  Notwithstanding the foregoing, in the event InSite chooses to
                  reference the CVO Data in its regulatory filings, and InSite
                  obtains approval for an NDA for the SAC Product or Other
                  Product, CVO shall pay InSite a royalty * * * of CVO's Net
                  Sales of the applicable Product during the CVO Royalty Period.
                  [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
                  TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED
                  MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION
                  PURSUANT TO RULE 24b-2.]

            4.3   On the other hand, in the event InSite completes the
                  development of the SAC Product or Other Product and the
                  formulation for any such Product is sufficiently similar to
                  the formulation for the Glaucoma Product as to legally allow
                  prescription substitution of one product by the other, CVO
                  shall pay to InSite a royalty * * * of CVO's Net Sales of such
                  Product if InSite has referenced the CVO Data in obtaining
                  approval of the NDA therefor, or * * * of such Net Sales if
                  InSite has not referenced CVO Data in obtaining approval of
                  the NDA therefor. [* INDICATES THAT MATERIAL HAS BEEN OMITTED
                  AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL

                  COMMISSION PURSUANT TO RULE 24b-2.]

            4.4   (a) In the event InSite elects not to complete the development
                      of the SAC Product or Other Product, and CVO completes
                      such development and obtains an approval for the NDA
                      therefor, and such Product has a different formulation
                      from and cannot be legally substituted for the Glaucoma
                      Product, CVO shall pay the following royalties depending
                      on the stage at which InSite has stopped development of
                      the applicable Product:

                        Prior to Commencement of Phase II                    *
                        Prior to Commencement of Phase III                   *
                        After Commencement of Phase III                      *

                      SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE
                      COMMISSION PURSUANT TO RULE 24b-2.]

                      For purposes of this Agreement, "Phase II" and "Phase III"
                      shall have the meaning given them in the United Stated
                      Food and Drug Act and any rules or regulations promulgated
                      thereunder.

            (b)       Nothwithstanding the foregoing, if after InSite has
                      initiated but not completed Phase III, CVO completes the
                      development of the SAC Product or Other Product, and such
                      Product can be legally substituted for the Glaucoma
                      Product, then the royalty rate payable to CVO for such
                      Product shall be * * * spent by CVO in development costs
                      for such Product down to a minimum rate of * * * [*
                      INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
                      TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED

                      PURSUANT TO RULE 24b-2.].

            4.5   In the event InSite has referenced CVO Data in obtaining
                  approval of the NDA for the Glaucoma Product, whether or not
                  such Product is the same formulation as the SAC or Other
                  Products, InSite shall pay CVO a royalty of * * * InSite's Net
                  Sales of the Glaucoma Product until the expiration of the last
                  to expire of the patents covering Voltaren Ophthalmic. [*

            4.6   The royalties payable by CVO to InSite in Section 4.2, 4.3 and
                  4.4 hereof, shall

                  be adjusted by adding an additional * * * of Net Sales to the
                  otherwise applicable royalty rate if the SAC Product or Other
                  Product is formulated with an InSite Novel Preservative. Such
                  royalties shall be reduced by * * * if the applicable Product
                  is formulated and developed with a CVO Novel Preservative, * *
                  * and by * * *, if formulated and developed with both a CVO
                  Novel Preservative and CVO's novel * * * replacement provided
                  these formulations are not covered by any patent issuing from
                  * * *. It is agreed and understood that the parties will have
                  to mutually agree on the best formulation for such product
                  with respect to preservative, based on the most desirable
                  product and the ability to expedite development of the
                  product. InSite shall pay to CVO a royalty of * * * of

                  any patent issuing from * * *. Such additional royalties shall
                  be paid by InSite until the expiration of the last patent

         5. TIMING OF ROYALTY PAYMENTS; RECORDS

            5.1   Within forty-five (45) days after the end of each calendar
                  quarter, CVO shall pay to InSite and InSite shall pay to CVO
                  the royalty payments due, if any, for that quarter in U.S.
                  dollars.

            5.2   Together with each quarterly royalty payment, the party paying
                  the royalty shall submit to the other a written accounting
                  showing its computation of royalties due under this Agreement
                  for such quarter. Said accounting shall set forth gross sales,
                  Net Sales, and the total royalties due for the quarter in
                  question.

            5.3   Each party shall keep full and accurate books and records
                  reflecting its sales of the Products and the data used in
                  arriving at Net Sales and the amount of royalties payable to
                  the other party hereunder for no less than one (1) year after
                  the end of each such quarter. Each party shall permit the
                  other, at the other party's expense, to have such books and
                  records examined by independent certified public accountants
                  retained by the other party and acceptable to such party,
                  during regular business hours upon reasonable advance notice,
                  but not later than one (1) year following the rendering of any
                  such reports, accounting and payments, and no more often than
                  one (1) time per year. Such independent accountants shall keep
                  confidential any information obtained 


                                       8
<PAGE>   9
                  during such examination and shall report to the party who
                  retained each accountant only the amounts of royalties which
                  the independent accountant believes to be due and payable
                  hereunder. If errors of ten percent (10%) or more in the
                  auditing party's favor are discovered as a result of such
                  examination, the audited party shall reimburse the auditing
                  party for the expense of such examination and pay the
                  deficiency immediately.

         7. TRANSFER AND OWNERSHIP OF KNOW-HOW

                  7.1     As part of the license granted in Section 2.1 and 2.2,
                          and in order to enable CVO to develop, make, have
                          made, use and sell the SAC Product and the Other
                          Products, InSite shall either (i) make available to
                          CVO all Know-How related to the development of such
                          SAC Product or Other Products at the time that InSite
                          elects not to complete the development of such Product
                          and to turn the development of such Product over to
                          CVO, or (ii) make available to CVO all Know-How
                          related to marketing of such SAC Product or Other
                          Products at the time CVO launches such Product(s). All
                          Know-How related to the development and/or marketing
                          of the SAC Product or Other Products generated or
                          obtained by InSite during the Agreement Period shall
                          be made available to CVO within thirty (30) days of
                          its generation or receipt by InSite; provided,
                          however, InSite shall have no obligation to make
                          available any Know-How to CVO prior to InSite's
                          election not to complete development of the SAC
                          Product or one of the Other Products. All Know-How
                          provided to CVO shall be deemed confidential
                          information and shall be subject to the
                          confidentiality restrictions set forth in this
                          Agreement.

                  7.2     In the event CVO takes over the development of the SAC
                          or Other Products, InSite shall assign to CVO the IND
                          for such Product and the data contained therein, and
                          all pre-clinical data and regulatory submissions for
                          such Product, but InSite shall retain rights to use
                          any data contained in the IND for such Product and any
                          pre-clinical data and the right to access the same
                          subject to the terms of this Agreement. CVO shall own
                          all subsequent regulatory submissions for such
                          Product, including the NDA therefor and the data
                          contained therein, subject to InSite's rights to
                          access the same. InSite shall be authorized to
                          reference such submissions with respect to its other
                          products and in the event it wishes to manufacture or
                          market such Products pursuant to Section 2.3 hereof.

         8. CONFIDENTIALITY

                  8.1     InSite and CVO shall keep any Know-How or business
                          information provided or made available by the other
                          party or its Affiliates hereunder confidential, and
                          neither InSite nor CVO shall, without the prior
                          written consent of the other party or its Affiliates,
                          as the case may be, use (except as expressly permitted
                          by this Agreement), or disclose to any third party,
                          any Know-How or business information provided or made
                          available by the other party or its Affiliates
                          hereunder; provided, however, that the foregoing shall
                          not apply to information which the party receiving
                          such information can establish by written
                          documentation to (i) have been publicly known at the
                          time of disclosure by the other party or its
                          Affiliates, as the case may be, (ii) have become
                          publicly known, without fault on its part, subsequent
                          to such disclosure, (iii) have been 


                                       10
<PAGE>   11
                          otherwise known by it from a source (other than the
                          other party or its agents or Affiliates), lawfully
                          having possession of and the right to disclose such
                          information, or (iv) have been developed by it or its
                          Affiliates independently of the disclosure by the
                          other party or its Affiliates without use of the other
                          party's Confidential Information.

                          The foregoing shall not preclude the disclosure of
                          information by InSite or CVO:

                          (a)     to its legal representatives, Affiliates,
                                  consultants, outside contractors and (if it
                                  has the right to grant the license or
                                  sublicense) its licensees and sublicensees,
                                  under like written confidentiality obligations
                                  on the part of the recipients, or

                          (b)     to the extent required by law or regulation,
                                  provided that, to the extent reasonably
                                  possible, it shall give prompt written notice
                                  of the proposed disclosure to the other party
                                  or its Affiliates, as the case may be, to
                                  allow the other party or its Affiliates, as
                                  the case may be, an opportunity to object to
                                  such requirement and, if applicable, assure
                                  that confidential treatment will be accorded
                                  to such information, or

                          (c)     to the extent that such information is
                                  reasonably required to be disclosed for the
                                  purpose of securing necessary governmental
                                  authorization for the clinical testing or
                                  marketing of Products, or for the purpose of
                                  conducting clinical testing or marketing of
                                  Products, or of prosecuting or defending
                                  litigation.

                  8.2     The terms of this Agreement shall not be disclosed by
                          either party to any third party (other than as
                          provided in Sub-sections 8.1(a), (b) and (c) or be
                          published unless both parties expressly agree
                          otherwise in writing. Furthermore, neither party shall
                          use the name of the other party or its Affiliates for
                          commercial purposes without their prior written
                          consent. However, all of the foregoing restrictions
                          shall not apply to the disclosure of information set
                          forth in the form of an agreed upon press release, if
                          any, which may be prepared in mutually agreeable
                          format and substance for release when this Agreement
                          becomes effective, or to disclosures required by law
                          or regulation including, without limitation, SEC
                          reporting requirements or FDA documentation relating
                          to Products.

         9. PATENTS

                  9.1     CVO acknowledges and agrees that the Regents of the
                          University of California (the "Regents") is solely
                          responsible for the prosecution and maintenance of the
                          Patent Rights in the Territory at InSite's expense.
                          InSite agrees that it will continue to meet its
                          reimbursement obligations to the Regents.

         10. INFRINGEMENT OF PATENT RIGHTS

                  10.1    If either party shall become aware of any infringement
                          or threatened infringement of any Patent Rights,
                          including that contained in a notice provided under
                          the 1984 Act by a party filing an ANDA or Paper NDA
                          for any of the Products, then the party having such
                          knowledge shall give notice to the other within ten
                          (10) days of becoming aware of such infringement or
                          threatened infringement.

                  10.2    InSite shall have the right to take such action, as it
                          deems appropriate, whether by action, suit, proceeding
                          or otherwise, at its own expense to prevent or
                          eliminate, the infringement of Patent Rights by others
                          and to collect damages. CVO agrees to cooperate with
                          InSite in any reasonable manner including, but not
                          limited to, being named as a co-plaintiff in an action
                          brought by InSite. InSite agrees to pay all reasonable
                          out-of-pocket expenses (other than legal fees)
                          incurred by CVO at the request of Insite, in the
                          prosecution of any such action, suit or proceeding for
                          infringement. Except for an action brought by the
                          Regents, either alone or jointly with InSite, any
                          damages recovered by the party bringing the action for
                          patent infringement shall be used first to compensate
                          that party for its out-of-pocket expenses in the
                          prosecution of any such action, suit or proceeding for
                          infringement and any remaining damages recovered by
                          that party shall be apportioned between InSite and CVO
                          in proportion to the damage incurred by each party
                          determined in such action, suit or proceeding as a
                          result of the infringement.

                  10.3    In the event of any substantial and adverse
                          infringement (defined as having a material effect on
                          the sales or future sales of any of the Products), if
                          an action for patent infringement is not initiated by
                          InSite pursuant to Section 10.2 or by the Regents,
                          either alone or jointly with InSite, to prevent or
                          eliminate the infringement of Patent Rights within
                          ninety (90) days of receipt of notice of the
                          infringement or threatened infringement thereof (or
                          within thirty (30) days in the event such infringement
                          is by notice under the 1984 Act) then within said
                          ninety (90) days (or thirty (30) days, if applicable),
                          CVO may, at its option, give notice to InSite that
                          unless InSite undertakes such action, CVO shall
                          commence an action to terminate such infringement. If
                          InSite fails to take such action within said ninety
                          (90) days then CVO shall have the right to take such
                          action, at its own expense, as it deems appropriate
                          against any infringer of 

                                       12
<PAGE>   13
                          same. Such action by CVO may be undertaken in the name
                          of InSite, if necessary, and InSite agrees to
                          cooperate with CVO, and execute any necessary
                          documents relating to such action. In the event the
                          parties fail to bring such action to prevent or
                          eliminate the infringement of Patent Rights within one
                          hundred eighty (180) days of receipt of notice and
                          unless InSite believes, based upon an opinion of its
                          counsel, that the activity in question does not
                          infringe the Patent Rights, CVO's obligation to pay
                          patent royalties under Section 3 hereof shall be
                          abated, only with respect to the specific Products
                          claimed by the Patent Rights being infringed, until
                          such time as InSite shall obtain discontinuance of
                          such infringement.

                          At any time after commencement of any such
                          infringement action by CVO, InSite shall have the
                          right to become a party plaintiff in such action, and
                          InSite shall have the right to assume the prosecution,
                          conduct and control of such action at InSite's
                          expense. Any recoveries in an action commenced by CVO
                          shall be apportioned as specified by Section 10.2

         11. THIRD PARTY RIGHTS

                  11.1    If either party shall become aware of any action, or
                          suit, or threat of action or suit, by a third party
                          alleging that the manufacture, use or sale of the SAC
                          Product or Other Product or the practice of Know-How
                          infringes a U.S. patent, or violates any other
                          proprietary rights in the Territory of any third
                          party, the party aware shall promptly notify the other
                          party of the same and fully disclose the basis
                          therefor.

                  11.2    InSite shall have the sole right at its own expense to
                          compromise or defend any such action or suit, or
                          threat of action or suit, on such basis and on such
                          terms as InSite may determine as appropriate in its
                          sole discretion, in its own name, or jointly in the
                          name of CVO and InSite as may be deemed necessary or
                          appropriate by InSite, and provided that CVO shall
                          have the right to participate at its own expense.
                          InSite shall keep CVO reasonably informed as to the
                          status of, and basis for, any such claim and shall
                          consult with CVO from time to time as to the defense
                          of such suit or action. CVO shall cooperate fully with
                          InSite in the defense of such suit or action,
                          including, without limitation, by making all relevant
                          papers and records available to InSite and by making
                          CVO's employees available for interviews and
                          depositions and InSite agrees to pay all reasonable
                          out-of-pocket expenses incurred by CVO at the request
                          of InSite. Notwithstanding the foregoing, neither
                          party shall have the right to settle any such claim
                          without the prior written consent of the other party,
                          which consent shall not be unreasonably withheld.

                  11.3    If, by the terms of any settlement approved by InSite,
                          which approval shall not be unreasonably withheld, or

                          tribunal or other authority of competent jurisdiction,
                          CVO is required to obtain a license from a third party
                          in order to develop, make, have made, use or sell SAC
                          Product or Other Products (hereinafter "Third Party
                          License") and to compensate or pay damages to such
                          third party and/or pay royalties under such license,
                          then any royalties payable under Section 4 of this
                          Agreement shall be reduced by (a) any damages paid or
                          payable by CVO to such other party and (b) the amount
                          of royalties payable to the third party on future
                          sales under such Third Party License, provided the
                          amount of the reduction in the aggregate shall not be
                          greater than one-half (1/2) of the royalties
                          previously and hereafter payable to InSite pursuant to
                          this Agreement.

                          The reduction of royalties shall not apply to any SAC
                          Product or Other Products at issue in such action or
                          suit, or threat of action or suit, to the extent the
                          infringement is the direct result of such Product's
                          being (i) made in whole or in part in accordance to
                          new specifications delivered after the date of this
                          Agreement; or (b) combined with other products or
                          processes. CVO will indemnify InSite and its officers,
                          directors, agents and employees from all damages,
                          settlements, attorneys' fees and expenses related to a
                          claim of infringement or misappropriation excluded
                          from CVO's right to reduce royalties by this sentence
                          and related to the sale of Products by CVO.

                  11.4    Nothing in this Section 11, or in Section 10, shall be
                          construed as a waiver or cure of any breach of any
                          warranties set forth in Section 6 or any release of
                          any claim by CVO as may be appropriate relating
                          thereto.

         12. PRODUCT LIABILITY

                  12.1    CVO shall defend, indemnify and hold InSite harmless
                          from any product liability claims and from any product
                          liability damages arising from the manufacture, use,
                          sale or importation by CVO of the SAC Product or Other
                          Products in the Territory, provided that InSite
                          notifies CVO of any such claims within ten (10) days
                          of receipt thereof and reasonably cooperates with CVO
                          in defending against such claims. CVO shall have
                          complete control and over the defense and/or
                          disposition of any such claim.

                  12.2    InSite shall defend and hold CVO harmless from any
                          product liability claims and from any product
                          liability damages arising from the manufacture, use,
                          sale or importation by InSite of the Glaucoma Product,
                          SAC Product or Other Products, provided that CVO
                          notifies InSite of any such claims within ten (10)
                          days of receipt thereof and reasonably cooperates with
                          InSite in defending against such claims. InSite shall
                          have complete control over the defense and/or
                          disposition of any such claim.

                          and take any action reasonably necessary in connection
                          therewith.

                              (B)   FOR ANY MATTER BEYOND ITS REASONABLE
                                    CONTROL.

                          THE LIMITATIONS IN THIS SECTION 14 SHALL NOT APPLY TO

                  17.2    In the event of a breach or default of this Agreement
                          by either party which is not cured within ninety (90)
                          days after the receipt of notice thereof from the

                          performance of its obligations.

         19. ASSIGNMENT

                  19.1    This Agreement and all rights and obligations
                          hereunder are personal to the parties hereto and, may
                          not be assigned, except pursuant to Sections 2.3 and
                          2.4 hereof, without the express prior written consent
                          of the other. Notwithstanding the foregoing, either
                          party may assign this Agreement to an entity
                          controlled by, or under common control with or
                          representing a successor in interest without a change
                          in control of the original party. Any assignment or
                          attempt at same in the absence of such prior written
                          consent shall be void and without effect.

         20. GOVERNING LAW

                  20.1    This Agreement shall be governed by, and construed in
                          accordance with, the laws of the State of New York
                          without regard to conflicts of laws provisions
                          thereof.

         21. SEVERABILITY

                  21.1    If any one or more of the provisions of this Agreement
                          shall be held to be invalid, illegal or unenforceable,
                          the validity, legality or enforceability of the
                          remaining provisions hereof shall not in any way be
                          affected or impaired thereby. In the event any
                          provision shall be held invalid, illegal or
                          unenforceable, the parties shall use best efforts to
                          substitute a valid, legal and enforceable provision
                          which, insofar as possible, implements the purposes
                          hereof.

         22. NO WAIVER

                  22.1    The failure of any party hereto at any time or times
                          to require performance of any provisions hereof shall
                          in no manner affect its rights to enforce such
                          provision at a later time.

         23. ENTIRE AGREEMENT

                  23.1    This Agreement constitutes the entire understanding
                          between the parties relating to the subject matter
                          thereof, and no amendment or modification to this
                          Agreement shall be valid or binding upon the parties
                          unless made in writing and signed by the
                          representatives of such parties.

         2. GRANT

         2.1 (a) InSite hereby grants to CVO during the Agreement Period a
co-exclusive license or sublicense in the Territory and a non-exclusive license
or sublicense outside the Territory, in each case with the right to sublicense,
under the Patent Rights and unpatented Know-How referred to in the following
sentence, to develop, manufacture, have manufactured, use and sell the Agreement
Product for eye care.

             (b) Under the foregoing license and sublicense, CVO shall have the
co-



                                        2.
<PAGE>   3
exclusive right to manufacture, have manufactured and use the Agreement Product
anywhere in the world, but CVO's right to sell the Agreement Product shall be
limited to the Territory, and CVO shall not seek directly or indirectly to sell
the Agreement Product outside the Territory. (It is understood, however, that
CVO's contract manufacturer(s) for the Agreement Product may sell the same to
CVO anywhere in the world for sale by CVO in the Territory only.)

                  (c) Under the foregoing co-exclusive license and sublicense,
CVO (and CVO's sublicensees) shall share with InSite the exclusive right under
the Patent Rights and Know-How referred to above to manufacture, have
manufactured, use and sell the Agreement Product in the Territory. Such sale of
the Agreement Product in the Territory by InSite may be made using InSite's own
sales force or by InSite's engaging in marketing activities with other companies
or entities that do not (and whose Affiliates do not) at the time of the
initiation of such engagement participate in the prescription and/or
over-the-counter ophthalmic pharmaceutical markets in the Territory, it being
understood, however, that the foregoing does not prohibit InSite's own sales
force or such other companies or entities from marketing the Agreement Product
to normal distribution channels such as wholesalers, drugstore chains,
independent manufacturers or independent sales representatives or agents,
retailers and health care providers (e.g., health maintenance organizations,
physicians, and preferred provider organizations) that sell prescription and/or
over-the-counter ophthalmic pharmaceuticals. InSite shall use good business
judgment, taking into consideration the overall sales of the Agreement Product,
in selecting any such independent manufacturers or independent sales
representatives or agents.

         Under the foregoing license and sublicense, CVO's right to manufacture,
have manufactured and use the Agreement Product outside the Territory shall be
non-exclusive. Under this Agreement InSite reserves the right to manufacture,
have manufactured, use and sell the Agreement Product outside of the Territory,
and to sublicense such rights outside of the Territory.

         2.2 The right of InSite to manufacture, have manufactured, use and sell
Agreement Product in the Territory which are reserved in the foregoing paragraph
shall not in any way be assigned or transferred to any third party; provided,
however, that such right may be assigned or transferred in a merger,
reorganization, sale of all or substantially all of InSite's assets, or
transaction whereby control of InSite changes, to InSite's successor in interest
in such transaction; provided, further, that upon the occurrence of any such
transaction InSite (or its successor in interest) shall not have the right to
sell any Agreement Product in any country in the respective Territory for such
Agreement Product except after the end of the fourth year following the date of
CVO's or CVO's Affiliates' first commercial sale in such country of such
Agreement Product (provided that such first commercial sale shall be deemed to
have occurred not later than one (1) year following the registration for sale of
such Agreement Product by the FDA or corresponding foreign agency for such
country with respect to either CVO or InSite), at which time InSite's right for
such Agreement Product may be assigned, transferred or sublicensed without
restriction hereunder.

         2.3 With respect to any Agreement Product and any country in the
Territory, until the end of the fourth year following the date of CVO's or CVO's
Affiliates' first commercial sale of such Agreement Product in such country
(provided that such first commercial sale shall be deemed to 


                                       3.
<PAGE>   4
have occurred not later than one (1) year following the registration for sale of
such Agreement Product by the FDA or corresponding foreign agency for such
country with respect to either CVO or InSite), CVO's right to grant any
sublicense under the Patent Rights and Know-How licensed or sublicensed by
InSite to CVO under this Article 2 shall be limited to sublicensing CVO's
Affiliates; and after such four (4) year period, CVO shall have the right to
grant such a sublicense to any third party to manufacture, have manufactured,
use and sell such Agreement Product in such country, provided, however, that if
CVO grants any such sublicense to any third party (other than CVO's Affiliates)
to sell such Agreement Product in such country, then the royalties payable by
such sublicensee to CVO shall not be less than * * * of such sublicensee's Net
Sales for such Agreement Product in such country, and with respect to such
Agreement Product CVO shall pay to InSite one-half of the excess of royalties
received by CVO from such sublicensee for such sublicensee's Net Sales in such
country, over the royalties payable by CVO to InSite resulting from such
sublicensee's Net Sales in such country under Article 5 below. CVO shall provide
InSite with a copy of the contractual provisions for any such sublicense to any
third party (other than CVO's Affiliates) which deal with royalty rates and
compensation, which copy shall be maintained in confidence by InSite pursuant to
Article 7 hereof. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         2.4 Unless this Agreement is terminated for cause by InSite under
Sections 15.2 or 15.3, at the end of the Agreement Period for any Agreement
Product in any country in the Territory, CVO shall have the unrestricted
perpetual right to use the Patent Rights and Know-How that are licensed or
sublicensed by InSite above, free of charge, to manufacture, have manufactured,
and use such Agreement Product anywhere in the world and to sell such Agreement
Product in such country.

         2.5 CVO shall use commercially reasonable efforts consistent with good
business judgment to commercialize and sell the Agreement Product in the
Territory.

         2.6 CVO shall hereby be granted the limited right and license during
the Agreement Period and thereafter, unless CVO's rights are terminated pursuant
to Sections 15.2 or 15.3, to use InSite's DuraSite trademark solely in
connection with the marketing and sale of the Agreement Product.

         3. ROYALTIES

         3.1 In consideration of the rights granted in Section 2, during the
Royalty Period, CVO shall pay InSite royalties * * * of Net Sales of the
Agreement Product in the Territory so long as there is an enforceable, issued,
valid and unexpired patent identified in Patent Rights in the Territory covering
the Agreement Product. In the event there are no enforceable and valid patents
identified in the Patent Rights in the Territory, on a country-by-country basis,
the royalty rate hereunder shall be * * * of Net Sales. [* INDICATES THAT
MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED
THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE
COMMISSION PURSUANT TO RULE 24b-2.]


                                       4.
<PAGE>   5
         3.2 Sales of the Agreement Product between or among CVO, its Affiliates
and sublicensees shall not be subject to any royalty hereunder, and in such
cases royalties shall be calculated upon CVO or its Affiliates' or sublicensees'
Net Sales to an independent third party. CVO shall be responsible for payment of
any royalty accrued on Net Sales of the Agreement Product to such independent
third party through CVO's Affiliates or sublicensees. Royalties shall accrue
hereunder only once in respect of the same unit of the Agreement Product.

         4. TIMING OF ROYALTY PAYMENTS; RECORDS

         4.1 Within 45 days after the end of each calendar quarter during the
Royalty Period, CVO shall pay to InSite the royalty payment due for that quarter
in U.S. dollars.

         4.2 Together with each quarterly royalty payment, CVO shall submit to
InSite a written accounting showing its computation of royalties due under this
Agreement for such quarter. Said accounting shall set forth gross sales, Net
Sales, and the total royalties due for the quarter in question.

         4.3 CVO shall keep full and accurate books and records reflecting the
sales of Agreement Product and the data used in arriving at Net Sales and the
amount of royalties payable to InSite hereunder for no less than one year after
the end of each such quarter. CVO shall permit InSite, at InSite's expense, to
have such books and records examined by independent certified public accountants
retained by InSite and acceptable to CVO, during regular business hours upon
reasonable advance notice, but not later than one year following the rendering
of any such reports, accounting and payments, and no more often than one time
per year. Such independent accountants shall keep confidential any information
obtained during such examination and shall report to InSite only the amounts of
royalties which the independent accountant believes to be due and payable
hereunder.

         5. WARRANTIES

         5.1 InSite warrants and represents that:

             (a) it is the owner of the Patent Rights and Know-How and has the
right to license, in the manner set forth in this Agreement, said Patent Rights
and Know-How free of any lien or encumbrance in the Territory;

             (b) it has not assigned or conveyed any interest in the Patent
Rights or Know-How which may be inconsistent with the rights granted hereunder;

             (c) to the best of its knowledge and after a diligent search, the
practice of the Patent Rights and Know-How in the Territory does not infringe
any rights of third parties;

             (d) it is not aware that any third party is infringing the Patent
Rights;

             (e) it is a corporation duly incorporated and in good standing in
its state of 

                                       5.

incorporation and has all requisite power to enter into and perform this
Agreement. Upon execution by the parties hereto, this Agreement shall constitute
a valid and legally binding obligation of InSite, enforceable in accordance with
its terms; and

             (f) it has prosecuted all patent applications within the Patent
Rights in good faith and has no reason to believe that any patent included
within the Patent Rights would be invalid or would be held to be unenforceable
by the court of competent jurisdiction.

         6. TRANSFER AND OWNERSHIP OF KNOW-HOW; TRANSFER OF ADVERSE DRUG
REACTION INFORMATION

         6.1 As part of the license granted in Section 2 hereof, and in order to
enable CVO to develop, make, have made, use and sell the Agreement Product,
InSite shall provide CVO with access to all Know-How within thirty days after
signing this Agreement. All Know-How generated or obtained by InSite during the
Agreement Period shall be made available to CVO within thirty days of its
generation or receipt by InSite. All such Know-How shall be provided to CVO as
confidential information subject to the confidentiality restrictions set forth
in this Agreement.

         6.2 InSite shall also assign to CVO the IND for the Agreement Product
and the data contained therein, and all pre-clinical data and regulatory
submissions for the Agreement Product, provided that InSite shall retain the
right to reference and use any of the foregoing for its own purposes consistent
with the terms of this Agreement. CVO shall own all subsequent regulatory
submissions for the Agreement Product, including the NDA therefor, and the data
contained therein. InSite understands and agrees that it shall not have any
ownership, or license rights in, or to, such submissions or other regulatory
filings of CVO for the Agreement Product, except that InSite shall be authorized
to reference such submissions in the event it wishes to manufacture or market
the Agreement Product pursuant to Section 2.4 hereof. CVO shall also have access
and a right of reference to any regulatory submissions made by InSite with
respect to the Agreement Product.

         6.3 All research and other information developed by CVO and its
Affiliates shall remain the property of CVO or its Affiliates, but InSite shall
have the right to access and reference such research and other information if it
decides to manufacture the Agreement Product pursuant to Section 2.4 hereof.

         6.4 During the Agreement Period, InSite shall report to CVO as soon as
practicable, and no later than five days following InSite's own notification,
any findings associated with the use of Agreement Product that may suggest
significant hazards, significant contraindications, significant side effects or
significant precautions pertinent to the safety of Agreement Product. In
addition, InSite shall provide CVO with notice of all adverse reaction
information in sufficient time to enable CVO to meet all requirements for
reporting such adverse reactions in the Territory.

         7. CONFIDENTIALITY

         7.1 InSite and CVO shall keep any Know-How or business information
provided 

                                       6.
<PAGE>   7
or made available by the other party or its Affiliates hereunder confidential,
and neither InSite nor CVO shall, without the prior written consent of the other
party or its Affiliates, as the case may be, use (except as expressly permitted
by this Agreement or for the purposes of this Agreement), or disclose to any
third party, any Know-How or business information provided or made available by
the other party or its Affiliates hereunder, provided, however, that the
foregoing shall not apply to information which the party receiving such
information can establish by written documentation to (i) have been publicly
known at the time of disclosure by the other party or its Affiliates, as the
case may be, (ii) have become publicly known, without fault on its part,
subsequent to such disclosure, (iii) have been otherwise known by it from a
source (other than the other party or its agents or Affiliates), lawfully having
possession of such information, or (v) have been developed by it or its
Affiliates independently of the disclosure by the other party or its Affiliates.

         The foregoing shall not preclude the disclosure of information by
InSite or CVO

             (a) to its legal representatives, Affiliates, consultants, outside
contractors and (if it has the right to grant the license or sublicense) its
licensees and sublicensees, under like confidentiality obligations on the part
of the recipients, or

             (b) to the extent required by law or regulation, provided that, to
the extent reasonably possible, it shall give prompt written notice of the
proposed disclosure to the other party or its Affiliates, as the case may be, so
as to allow the other party or its Affiliates, as the case may be, an
opportunity to object to such requirement and, if applicable, assure that
confidential treatment will be accorded to such information, or

             (c) to the extent that such information is reasonably required to
be disclosed for the purpose of securing necessary governmental authorization
for the clinical testing or marketing of products or for the purpose of
conducting clinical testing or marketing of products, or of prosecuting or
defending litigation.

         7.2 The terms of this Agreement shall not be disclosed by either party
to any third party (other than as provided in Sub-sections 7.1(a), (b) and (c)
above) or be published unless both parties expressly agree otherwise in writing.
Furthermore, neither party shall use the name of the other party or its
Affiliates without their prior written consent. However, all of the foregoing
restrictions shall not apply to the disclosure of information set forth in the
form of an agreed press release, if any, which may be prepared in mutually
agreeable format and substance for release when this Agreement becomes
effective, or to disclosures required by law or regulation.

         8. PATENTS

         8.1 InSite shall undertake and shall bear all costs of the prosecution
and maintenance of the Patent Rights in the Territory. InSite shall employ
reasonable efforts to keep CVO fully and timely informed in respect to the
course and conduct of patent application prosecution matters within the scope of
Patent Rights.



                                       7.
<PAGE>   8
         8.2 If InSite elects to terminate either the prosecution or maintenance
of the Patent Rights prior to the completion of normal prosecution before the
patent examiner or prior to the end of the term for maintenance, as the case may
be, it will give CVO 60 days prior written notice of such election prior to any
time limit on any action due. CVO, upon receipt of such notice, shall have the
option to undertake the continuation of such prosecution or maintenance and
InSite will transfer title to CVO for such patent application or patent.

         9. INFRINGEMENT OF PATENT RIGHTS

         9.1 If either party shall become aware of any infringement or
threatened infringement of any Patent Rights, including that contained in a
notice provided under the 1984 Act by a party filing an ANDA or Paper NDA for
Agreement Product, then the party having such knowledge shall give notice to the
other within 10 days of becoming aware of such infringement or threatened
infringement.

         9.2 CVO shall have the right to take such action, as it deems
appropriate, whether by action, suit, proceeding or otherwise, at its own
expense to prevent or eliminate, the infringement of Patent Rights by others and
to collect damages. InSite agrees to cooperate with CVO in any reasonable manner
including, but not limited to, being named as a co-plaintiff in an action
brought by CVO. CVO agrees to pay all reasonable out-of-pocket expense incurred
by InSite, in the prosecution of any such action, suit or proceeding for
infringement. Any damages recovered by the party bringing the action for patent
infringement shall be used to compensate that party for its out-of-pocket
expenses in the prosecution of any such action, suit or proceeding for
infringement. Any remaining damages recovered by that party shall be apportioned
between InSite and CVO in proportion to the damage incurred by each party as a
result of the infringement. To the extent that CVO cannot compensate its
out-of-pocket expenses in prosecuting said action by the recovered damages, CVO
may set off up to fifty percent (50%) of its reasonable out-of-pocket expenses
against royalties otherwise owed to InSite under this Agreement until CVO
reaches such 50% recovery point.

         9.3 In the event that CVO does not take action for patent infringement
pursuant to Section 9.2 to prevent or eliminate the infringement of Patent
Rights within 90 days of receipt of notice of the infringement or threatened
infringement thereof (or within 30 days in the event such infringement is by
Notice Under the 1984 Act), then within said 90 days (or within said 30 days if
such infringement is under the 1984 Act), InSite may, at its option, give notice
to CVO that unless CVO undertakes such action, InSite shall commence an action
to terminate such infringement. If CVO fails to take such action within said 90
days (or said 30 days in the event such infringement is by Notice Under the 1984
Act) then InSite shall have the right to take such action as it deems
appropriate against any infringer of same. Such action by InSite may be
undertaken in the name of CVO, if necessary, and CVO agrees to cooperate with
InSite, and execute any necessary documents relating to such action. In the
event the parties fail to bring such action to prevent or eliminate the
infringement of Patent Rights within 90 days of receipt of notice, CVO shall be
relieved of any obligation to pay patent royalties under Section 3 hereof until
such time as InSite shall obtain discontinuance of such infringement.

         At any time after commencement of any such infringement action by
InSite, CVO shall 


                                       8.
<PAGE>   9
have the right to become a party plaintiff in such action, and CVO shall have
the right to assume the prosecution, conduct and control of such action at CVO's
expense. Any recoveries in an action commenced by InSite shall be apportioned as
specified by Section 9.2.

         9.4 * * * [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         10. THIRD PARTY RIGHTS

         10.1 If either party shall become aware of any action, or suit, or
threat of action or suit, by a third party alleging that the manufacture, use or
sale of the Agreement Product or the practice of Know-How infringes a patent, or
violates any other proprietary rights of any third party, the party aware shall
promptly notify the other party of the same and fully disclose the basis
therefor.

         10.2 CVO shall have the right at its own expense to compromise or
defend any such action or suit, or threat of action or suit, on such basis and
on such terms as CVO may determine as appropriate in its sole discretion, in its
own name, or jointly in the name of CVO and InSite or in the name of InSite, as
may be deemed necessary or appropriate by CVO. CVO shall keep InSite reasonably
informed as to the status of, and basis for, any such claim and shall consult
with InSite from time to time as to the defense of such suit or action. InSite
shall cooperate fully with CVO in the defense of such suit or action, including,
without limitation, by making all relevant papers and records available to CVO
and by making InSite's employees available for interviews and depositions and
CVO agrees to pay all reasonable out-of-pocket expenses incurred by InSite at
the request of CVO.

         10.3 If, by the terms of any settlement or if by a judgment, decree or
decision of a court, tribunal or other authority of competent jurisdiction, CVO
is required to obtain a license from a third party in order to make, have made,
use, sell or import Agreement Product (hereinafter "Third Party License") and to
compensate or pay damages to such third party and/or pay royalties under such
license, then any royalties payable under Section 3 of this Agreement shall be
reduced by (a) any damages paid or payable by CVO to such other party and (b)
the amount of royalties payable to InSite on future sales under such Third Party
License, provided such reduction shall not be greater than one-half (1/2) of the
royalties previously and hereafter payable to InSite pursuant to this Agreement.

         10.4 Nothing in this Section 10, or in Section 9, shall be construed as
a waiver or cure of any breach of any warranties set forth in Section 5 or any
release of any claim by CVO as may be appropriate relating thereto.

         11. PRODUCT LIABILITY

         11.1 CVO shall defend and hold InSite harmless from any product
liability claims and from any product liability damages arising from the
manufacture, use, sale or importation by CVO of the Agreement Product in the
Territory, provided that InSite notifies CVO of any such claims within 10 days
of receipt thereof and cooperates with CVO in defending against such claims. CVO
shall have complete control over the defense and/or disposition of any such
claim.


                                       9.
<PAGE>   10

care in using the Equipment that B&L exercises with its own comparable
equipment, but in no event will such standard of care be lower than the standard
of care commonly practiced by pharmaceutical manufacturers in the United States
with respect to comparable equipment. Without limiting the foregoing, B&L shall,
at its own expense, subject to InSite's obligations with respect to the
Equipment herein contained, be responsible for repairing, servicing and
maintaining the Equipment in good working order, excluding reasonable wear and
tear.

         4.2 Use of Equipment. Use of the Equipment by B&L shall be dedicated,
on a first priority basis, to manufacturing InSite's requirements for Product in
accordance with the terms of this Agreement. Subject to the foregoing, B&L shall

Products manufactured using the Equipment and sold or transferred by B&L during
the preceding royalty period. Notwithstanding anything contained herein to the
contrary, in the event that FDA does not approve the NDA for PilaSite (as
defined in the PilaSite License Agreement), B&L shall receive a credit against
royalties payable to InSite hereunder equal to * * *. [* INDICATES THAT MATERIAL

                               PRODUCT DEVELOPMENT

         5.1 Drug Master File. B&L shall exercise its reasonable efforts to
develop a DMF covering the manufacture of the Product at the Facility promptly
following the date hereof. Such efforts shall be consistent with those employed
by B&L for other customers of B&L for contract manufactured product. B&L shall
allow InSite to reference the DMF in the course of seeking and obtaining FDA
approval of the NDA, and shall provide InSite with a DMF reference letter;
provided, however, that B&L's obligation to disclose to InSite the contents of
the DMF shall be limited to those sections which pertain to B&L's manufacture of
the Product. B&L shall be responsible for preparing and providing to InSite the
CMC section of the NDA.

         5.2 Clinical Trial Material. B&L agrees to exercise reasonable efforts
to supply InSite with its requirements of clinical trial batches of Product and
PilaSite (as defined in the PilaSite License Agreement) ("Clinical Trial
Material") when and as ordered; provided that B&L shall not be required to make
delivery of such Clinical Trial Material any earlier than 60 days following
receipt of an order from InSite.

         5.3 Validation Services. Following the execution of this Agreement, B&L
shall manufacture and validate stability batches of the Product in accordance
with GMP requirements and as necessary for InSite to file and obtain FDA
approval of the NDA; provided, that, in the event that B&L, after five good
faith attempts is unable to successfully manufacture, stability test and
validate three QA/QC-release lots of Product for NDA registration purposes, B&L
and InSite shall equally share all costs incurred in connection with the
manufacture, stability testing and validation of three additional QA/QC-release
lots for NDA registration purposes (the "Additional Stability Studies"); 


                                       7.

InSite's chief executive officer shall, within 10 days, meet to jointly
determine the appropriate action.

         5.4 Price. The price to be paid for Clinical Trial Material supplied to
InSite by B&L under Section 5.2 above shall be equal to * * *. Payment for the
Clinical Trial Material will be made in accordance with the payment provisions

HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         5.5 Delivery. B&L shall deliver the Clinical Trial Material to InSite
in the same manner as required for Product under Article VIII hereof.


                                   ARTICLE VI

                                SUPPLY OF PRODUCT

         6.1 Quantities. Throughout the Term, InSite agrees to order exclusively
from B&L all of its requirements of Product, and B&L agrees to manufacture and
supply InSite with such Product, as and where ordered by InSite in accordance
with the Specifications, GMPs, the NDA and the FFDCA; provided that if B&L fails
to satisfy InSite's requirements, it may purchase substitute Product from
sources other than B&L.

         6.2 Ordering Through Submittal of Rolling Forecast. During the Term,
InSite will provide B&L with a twelve (12) month rolling forecast of its
requirements by month for Product. Such rolling forecasts shall be delivered to
B&L by or on the tenth day of each month during the Term of this Agreement. The
first three months of each twelve month rolling forecast shall be binding on
InSite and shall constitute a firm purchase order ("Firm Purchase Order") for
the Product indicated for such months. B&L shall accept each Firm Purchase Order
by delivering a written order acknowledgment form to InSite within 30 days of
B&L's receipt of each Firm Purchase Order.

         6.3 InSite's Initial Rolling Forecast. InSite's initial twelve (12)
month rolling forecast by month shall be provided to B&L within thirty (30) days
of the date of FDA approval of the NDA.

         6.4 Orders Other Than Through Rolling Forecasts. Subject to the
provisions of Paragraph 6.2, InSite may submit additional purchase orders for
Product in excess of the quantities specified in the rolling forecasts. B&L
shall use its commercially reasonable efforts to accept and fill such orders
consistent with efforts used by B&L to

                                       8.
<PAGE>   9
fill excess orders for other customers of contract manufactured product.
Acceptance of such additional purchase orders shall be by written order
acknowledgment given to InSite.


                                   ARTICLE VII

                                 PRICE; PAYMENT

         7.1 Product Price. The price for Product manufactured and supplied by
B&L hereunder (the "Product Price") shall equal * * * of B&L's Manufacturing
Costs, plus * * * of Other Costs and Warehousing Costs. On a monthly basis, B&L
shall invoice InSite in an amount equal to the Product Price for that quantity
of Product delivered to InSite hereunder. InSite shall pay B&L's invoices by
check or wire transfer, as designated by B&L, within 30 days of receipt of B&L's
invoice. InSite agrees not to make any deductions of any kind from any payment
becoming due to B&L unless InSite has received an official credit memorandum
from B&L authorizing such deduction in accordance with its policies. [*

         7.2 Reconciliation. By December 15 of each calendar year throughout the
Term (and following the effective date of termination of this Agreement), B&L
shall prepare and deliver to InSite a detailed statement (the "Statement") which
provides a reconciliation of B&L's Manufacturing Costs for Product based upon
the actual quantity of Product delivered to InSite, as compared to B&L's
standard costs based upon the estimated quantities contained in the InSite
Volume Forecast. Based upon the Statement, B&L may make a positive or negative
adjustment to the Product Prices paid or payable to B&L based upon the actual
increase or decrease in Manufacturing Costs, which shall be satisfied by B&L or
InSite, as the case may be, within 60 days of InSite's receipt of the Statement.
Such adjustment shall be deemed accepted if not protested by InSite within 30
days of receipt of the Statement unless subsequently protested by InSite
pursuant to Section 22.7 below. If InSite protests B&L's calculation of an
adjustment to the Product Prices pursuant to this Section or Section 22.7 below,
and the parties are unable to mutually resolve the matter in protest, either
party may request to have the controversy settled by binding arbitration in
accordance with the then existing rules of the American Arbitration Association.

         Unless otherwise agreed in writing by the parties, one (1) month's
requirement of each Firm Purchase Order shall be delivered to InSite F.O.B.
B&L's loading dock at its facility in Tampa, Florida (the "F.O.B. Point"),
commencing within sixty (60) days of the date a Firm Purchase Order is received
by B&L, and continuing each month thereafter. At the request and expense of
InSite, B&L shall ship the Product ordered by InSite by such carrier or carriers
as InSite may designate. Such shipping instructions shall be submitted by InSite
to B&L. Unless otherwise agreed by the parties hereto, all risk of loss or
damage to the Product from any cause whatsoever shall be borne by InSite after
delivery to InSite or InSite's carrier at the F.O.B. Point.


                                   ARTICLE IX

         InSite shall develop all packaging, labeling and artwork for the
Product and shall select the InSite trademark ("InSite Trademark") to be used
for the Product. Thereafter, upon reasonable written notice, B&L will make, at
InSite's expense (which shall include reimbursement in an amount equal to B&L's
actual cost of any packaging components which are not used by B&L as a result of
a packaging change requested by InSite), any improvements or alterations to
packaging or labeling as requested by InSite and shall implement such
alterations or improvements at the earliest opportunity and otherwise as may be
necessary to allow InSite to comply with applicable law.

                        WARRANTIES; ACCEPTANCE AND CLAIMS

         10.1 Limited Product Warranty. B&L represents and warrants to InSite
that at the time of delivery, the Product manufactured and supplied hereunder
will conform to the NDA, GMPs and the FFDC Act, and other applicable laws and
regulations. THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER
WARRANTIES EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. EXCEPT WHERE
B&L COMMITS A WILLFUL, INTENTIONAL BREACH OF ANY MATERIAL PROVISION UNDER THIS
AGREEMENT, B&L SHALL NOT BE RESPONSIBLE OR LIABLE UNDER ANY PROVISION OF THIS
AGREEMENT OR UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL OR
EQUITABLE THEORY FOR ANY RESULTANT INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES INCLUDING, BUT NOT LIMITED TO LOSS OF REVENUES AND LOSS OF PROFITS FROM
B&L'S FAILURE TO PROVIDE THE PRODUCT TO INSITE OR OTHERWISE.

<PAGE>   11
         10.2 Notification of Defects. All Product shall be received subject to
InSite's inspection and may be rejected if any such Product fails to be in the
condition warranted hereunder. InSite shall be deemed to have accepted each
order of Product if B&L does not receive written notice to the contrary as set
forth in this Paragraph 10.2. InSite shall notify B&L in writing within 15 days
after delivery to InSite or its customers of any non-conforming Product
containing obvious defects discoverable without affecting the integrity of the
Product's packaging and within 30 days of its discovery of any latent defects,
or InSite's rights as to such obvious or latent non-conformance shall be waived
by InSite. At B&L's request, InSite shall promptly supply either some of the
Products which are allegedly defective or some other evidence of deficiency
which B&L shall specify. In the event of any dispute between B&L and InSite as
to whether any of the Products conform to the warranties hereunder, a sample of
the units in dispute shall be sent by InSite and B&L to a testing laboratory
mutually agreed to by B&L and InSite whose findings will be binding on the
parties except in cases of gross and manifest error. The cost of such testing
and Product shall be borne by the losing party.

         10.3 Returns. B&L shall accept for return and replacement any Product
manufactured and supplied to InSite under this Agreement which does not conform
with the warranty set forth above and for which proper notice has been given,
provided InSite obtains prior shipping authorization from B&L. All returns of
Product with obvious defects shall be in the original manufactured condition.
B&L will pay reasonable return freight and shipping charges, but InSite shall
assume the risk of loss in transit associated with such returns.


                                   ARTICLE XI

                       FDA INSPECTIONS AND COMMUNICATIONS


         InSite and B&L shall promptly notify the other party of any FDA

received by it from the FDA or any state or local authority with respect to the
Product and any GMP issues relating thereto and any written response,
information, data or correspondence delivered by such party to the FDA or any
state or local authority with respect to the Product and shall cooperate to the
extent reasonably requested by such other party in its response to the FDA or
such other state or local authority.


                                   ARTICLE XII

         12.1 Complaint Handling. In the event that InSite or B&L receives any
complaint, claims or adverse reaction reports regarding the Product, including
notices from the FDA regarding any alleged regulatory non-compliance of the
Product, each party shall, within five (5) business days, provide the other with
all information contained in the complaint, report, or notice and such
additional information regarding the Product as may be reasonably requested.
InSite shall comply, at a minimum, with FDA and GMP requirements for complaint
handling.

         12.2 Adverse Drug Reaction Reports. InSite shall establish a system for
monitoring, investigating and following-up on adverse reaction reports involving
the Product. If either party becomes aware that the Product contains a defect
which could or did cause death or injury, each party shall immediately by FAX
and telephone provide the other with a complete written description of all
relevant details known to such party concerning any such incident, including but
not limited to, a description of any defect and such other information which may
be necessary to report the incident to the FDA. InSite will be responsible for
preparing adverse drug reaction reports, administering adverse drug reaction
files relating to the Product and filing all such reports with FDA, at its sole
expense.

         12.3 Recordkeeping. B&L agrees to maintain internal records that will
permit the tracing of Product by lot number, so as to facilitate the tracing of
such Product in the event such tracing becomes necessary.

                                  ARTICLE XIII

                        ACCESS TO FACILITIES AND RECORDS

         Upon reasonable notice, each party shall have access during normal
business hours to inspect those areas of the facilities of the other party where
and at such times as Product is manufactured, packaged, tested or stored and to
review the records of the other party relating to the manufacturing, packaging
and quality control of the Product.

                      RIGHTS OF FIRST DISCUSSION AND OFFER

         For a period of one (1) year following the date of the First Closing
(as defined under that certain Stock Purchase Agreement between InSite and B&L
of even date herewith) in the event InSite desires to negotiate, or is solicited
to enter into, a corporate partnering, licensing or other transaction with a
third party with respect to the development, marketing or sale of the technology
and know-how related to the Product, 

                                      12.
<PAGE>   13
or any Additional Products (a "Third Party Corporate Transaction"), InSite shall
deliver written notice (the "Notice") to B&L which shall set forth its intention
to negotiate such Third Party Corporate Transaction and the terms thereof. For a
period of 60 days after the Notice is deemed to have been made in accordance
with this Agreement, InSite and B&L shall in good faith negotiate the terms of a
corporate partnering, licensing or other transaction substantially similar to
the Third Party Corporate Transaction (a "B&L Corporate Transaction"); provided,
however, that if B&L does not in good faith intend to pursue a B&L Corporate
Transaction, B&L shall notify InSite of such fact within 10 days of the date
that such decision is made. With respect to the Product and any other products
within the beta blocker category (excluding proprietary beta blockers of third
parties) only, B&L and InSite in good faith cannot agree on the terms of a B&L
Corporate Transaction within the 60 day period set forth above, or B&L earlier
notifies InSite that it does not intend to pursue such a transaction, InSite
shall be entitled to negotiate and enter into a Third Party Corporate
Transaction with any third party; provided that the terms and conditions thereof
are no more favorable to such third party than the terms set forth in the
Notice, if any; provided further, however, that if B&L made a definitive offer
to InSite with respect to the terms of a B&L Corporate Transaction which was not
accepted by InSite (the "B&L Offer"), then InSite shall not enter into any Third
Party Corporate Transaction with any third party pursuant to terms and
conditions which are on balance more favorable than the terms set forth in the
B&L Offer.

                                   ARTICLE XV

                                 PRODUCT RECALL

         To the extent permitted or required by law, any decision to recall,
withdraw or cease distribution of the Product as a result of a violation of the
NDA or of any law, rule or regulation, or because the Product presents a
possible safety risk may be made by either party after consulting with the other
party, and taking such reasonable action as InSite, as the owner of the NDA
under which the Product is manufactured may deem to be appropriate under the
circumstances to minimize the risk to both parties. Any such recall shall be
controlled by InSite; provided, however, that the parties shall use their best
efforts to work together to repossess the affected Product.

                                   ARTICLE XVI

                                 INDEMNIFICATION

         16.1 Indemnification of B&L. InSite shall indemnify, defend, save and
hold B&L and each of its Affiliates, officers, directors, employees and agents
harmless from and against Loss or Losses resulting from, or arising out of (a)
any material breach 

                                      13.
<PAGE>   14
of any warranty hereunder or material non-fulfillment or non-performance by
InSite of any agreement, covenant or obligation of InSite under this Agreement;
(b) any bodily injury arising as a result of a negligent act or omission of
InSite; (c) FDA enforcement action, inspections or Product recalls or market
withdrawals except where arising out of or resulting from B&L's failure to
manufacture Product in accordance with the terms of this Agreement; (d) InSite's
acts relating to the promotion, marketing and/or distribution of Product, except
where arising out of or resulting from B&L's failure to manufacture Product in
accordance with the terms of this Agreement; and (e) any actual or alleged
infringement or violation of any patent, trade secret or proprietary right
governing the Product.

         16.2 Indemnification of InSite. B&L shall indemnify, defend, save and
hold InSite and each of its Affiliates, officers, directors, employees and
agents harmless from and against Loss or Losses resulting from, or arising out
of (a) any material breach of any warranty hereunder or material non-fulfillment
or non-performance by B&L of any agreement, covenant or obligation of B&L under
this Agreement; (b) any actual or alleged defect in any Product manufactured and
delivered to InSite hereunder arising out of B&L's failure to manufacture
Product in accordance with the terms of this Agreement; (c) any actual or
alleged infringement or violation of any patent, trade secret or proprietary
rights used by B&L in manufacturing Product; and (d) FDA enforcement action,
inspection or Product recalls or market withdrawals resulting from B&L's failure
to manufacture the Product in accordance with the terms of this Agreement.

         16.3 Survival. The indemnification contained herein shall survive any
termination of this Agreement.

                                  ARTICLE XVII

                           INDEMNIFICATION PROCEDURES

         Upon the occurrence of an event which requires indemnification under
this Agreement, the Indemnified Party shall give prompt written notice to the
Indemnifying Party providing reasonable details of the nature of the event and
basis of the indemnity claim. The Indemnifying Party shall then have the right,
at its expense and with counsel of its choice, to defend, contest, or otherwise
protect against any such Action. The Indemnified Party shall also have the
right, but not the obligation, to participate at its own expense in the defense
thereof with counsel of its choice. The Indemnified Party shall cooperate to the
extent reasonably necessary to assist the Indemnifying Party in defending,
contesting or otherwise protesting against any such Action provided that the
reasonable cost in doing so shall be paid by the Indemnifying Party. If the
Indemnifying Party fails within thirty (30) days after receipt of such notice
(a) to notify the Indemnified Party of its intent to defend, or (b) to defend,
contest, or otherwise protect against such suit, action, investigation, claim or
proceeding, or fails to diligently continue 

                                      14.
<PAGE>   15
to provide such defense after undertaking to do so, the Indemnified Party shall
have the right, upon ten (10) days' prior written notice to the Indemnifying
party, to defend, settle and satisfy any such suit, action, claim, investigation
or proceeding and recover the costs of the same from the Indemnifying Party.

                                  ARTICLE XVIII

                                 CONFIDENTIALITY

         18.1 Confidentiality. Each party agrees that during the Term, and,
notwithstanding any other provision herein, for a period of five (5) years
thereafter (whatever the reason for termination), it will hold in confidence,
will not disclose to others and will not use for any purpose not contemplated by
this Agreement any technical or business information it obtains from the other
party in connection with this Agreement (collectively, the "Proprietary
Information"). These obligations shall not extend to any portion of the
Proprietary Information which:

                  (i) is known to the receiving party as documented by its
written records at the time of disclosure; or

                  (ii) is or becomes public or generally available to the public
through publication or otherwise but through no fault of the receiving party; or

                  (iii) corresponds in substance to information furnished to the
receiving party on a nonconfidential basis by a third party having a bona fide
right to do so and not having any confidential obligation, direct or indirect,
to the disclosing party with respect to same; or

                  (iv) corresponds to information furnished by the disclosing
party to any third party on a nonconfidential basis except in limited consumer
testing; or

                  (v) the receiving party can demonstrate was developed by the
receiving party independently of the disclosure of the Proprietary Information
by the disclosing party; or

                  (vi) is disclosed by the receiving party pursuant to a legal
requirement provided the receiving party has complied with the provisions set
forth in section (b) below.

         18.2 External Disclosure. If a party becomes legally required to
disclose any of the Proprietary Information, it will give the other party prompt
notice of such requirement so that the other party may seek a protective order
or other appropriate 

                                      15.
<PAGE>   16
remedy concerning such disclosure and will consult with the other party, if
requested to do so, regarding the nature and extent of such disclosure.

         18.3 Internal Disclosure. The parties agree that they will make the
Proprietary Information received available to persons within their organizations
only on a "need to know" basis and that all persons to whom such Proprietary
Information is made available will be made aware of the confidential nature of
the Proprietary Information and the restrictions comprised hereunder.

                                   TERMINATION

         19.1 Termination. This Agreement shall terminate upon the occurrence of
any of the following events or conditions, which termination shall automatically

action of the specified party where so indicated:

                  (i) The expiration of the Term;

                  (ii) The breach by either party of any provision of this
Agreement which is not cured within thirty (30) days from the date of written
notice delivered to the defaulting party in the case of a payment default, and
within ninety (90) days from the date of such notice in all other cases;
provided, however, that only the aggrieved party can terminate this Agreement
pursuant to this subsection (ii);

                  (iii) The mutual written agreement of the parties to this
Agreement;

                  (iv) The occurrence of any of the following: 

                          (A) the purchase by a Person of all or substantially
                  all of the assets of B&L or InSite; or

                          (B) the purchase by a Person of that number of shares
                  of the voting capital stock and/or securities convertible into
                  voting capital stock of B&L or InSite that after such purchase
                  will give such Person more than fifty percent (50%) of the
                  voting capital stock of B&L or InSite, determined on a fully
                  diluted basis; or

                          (C) a merger or consolidation of B&L or InSite with or

it of the anticipated closing date for the closing of such transaction and the
name of the Person acquiring such assets or stock or involved in such merger or

The right to enforce arbitration under this Article shall take precedent over
the right to terminate this Agreement and any exercise of the right of
termination pursuant thereto shall itself by subject to arbitration under this
Article upon mutual agreement of the parties.

         2.1 (a) InSite hereby grants to B&L during the Agreement Period a
license or sublicense, with the right to sublicense, under the Patent Rights and
unpatented Know-How referred to in the following sentence, to manufacture, have
manufactured, use, import and sell PilaSite for eye care. The Patent Rights and
Know-How licensed or sublicensed under this Section 2 shall consist of all of

In the event that, pursuant to the Supply Agreement, InSite's Additional Expense
Payments are less than * * *, B&L shall pay InSite an amount equal to * * * less
all Additional Expense Payments made by InSite upon the earlier to occur of (x)
January 15, 1997, (y) as determined in the reasonable judgment of B&L, the
successful completion of the Phase III clinical study report for the PilaSite
NDA. All payments provided for in this paragraph shall be made by wire transfer
in immediately available United States dollars to such account as InSite shall
specify in writing to B&L not less than two (2) days prior to the date such
payment is due. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

             (c) Under the foregoing license and sublicense, B&L (and B&L's
sublicensees) shall have the exclusive right under the Patent Rights and
Know-How referred to above to manufacture, import, have manufactured, use and
sell PilaSite anywhere in the world.

         2.2 (a) InSite shall take all steps necessary, and shall bear all
costs, to complete and submit an NDA for PilaSite with the FDA and shall use its
reasonable efforts (consistent with similarly situated companies) to cause such
NDA to be approved by FDA. Provided, however, that B&L shall be responsible for
performing and shall bear the costs of, except as otherwise provided herein, the
Services (as more fully described on Schedule 2.2(a) attached hereto).
Notwithstanding anything contained herein to the contrary, in the event that
B&L, after five (5) good faith attempts, is unable to successfully manufacture,
stability test and validate three (3) QA/QC-release lots of Product for NDA
registration purposes, B&L and InSite shall equally share all costs incurred in
connection with the manufacture, stability testing and validation of three (3)
additional QA/QC-release lots for 


                                       3.
<PAGE>   4
NDA registration purposes (the "Additional Stability Studies"); and provided,
further, that in the event that the parties are unable to successfully complete
the Additional Stability Studies, B&L's president and InSite's chief executive
officer shall, within ten (10) days, meet to jointly determine the appropriate
action. B&L shall provide InSite with all data and reports from the
aforementioned developmental activities for purposes of InSite's submission of
the NDA.

             (b) B&L may develop a drug master file ("DMF") covering its
manufacture of PilaSite. In the event that B&L undertakes to develop a DMF, it
shall not be required to exercise efforts beyond those employed by B&L for other
customers of B&L for contract manufactured product. B&L shall allow InSite to
reference the DMF in the course of seeking and obtaining FDA approval of the
NDA, and shall provide InSite with the DMF reference letter; provided, however,
that B&L's obligations to disclose to InSite the contents of the DMF shall be
limited to those sections which pertain to B&L's manufacture of PilaSite. B&L
shall be responsible for providing InSite with the CMC Section for inclusion in
the NDA.

             (c) B&L shall use its best commercial efforts consistent with good
business judgment, and shall bear all costs incurred therefor, to file
applications for regulatory approval of PilaSite in the Major Markets and shall
use reasonable efforts to cause such applications to be approved by all
necessary regulatory authorities in each Major Market. In the event that B&L
elects not to file applications for regulatory approval of PilaSite in any Major
Market within six (6) months of the date the PilaSite NDA is approved, or fails
to use reasonable efforts to cause any such applications to be approved by the
necessary regulatory authorities, or fails to maintain such regulatory
approvals, upon thirty (30) days advanced written notice by InSite, the license
granted by InSite to B&L in Section 2.1(a) above shall no longer be exclusive in
such Major Market. In such event, the royalty paid by B&L on sales of PilaSite
in such Major Market for which the license is no longer exclusive shall continue
to be calculated in accordance with Section 3 below; provided, however, that in
no event shall the royalty paid by B&L exceed the royalties paid by any other
nonexclusive licensee in such Major Market.

         2.3 B&L shall use commercially reasonable efforts consistent with good
business judgment, relevant to the country involved, to commercialize and sell
PilaSite in the Territory.

         2.4 In the event that, in the course of performing its obligations
hereunder prior to the approval for sale of PilaSite, either party is required
to expend sums or efforts that would render commercially impracticable its
activities to complete such approval, then the parties shall meet and discuss in
good faith, how and whether to proceed toward PilaSite approval.

                                       4.
<PAGE>   5
         3.1 (a) In consideration of the rights granted in Section 2 above,
during the Royalty Period in any country, B&L shall pay InSite royalties
consisting of * * * of Net Sales of PilaSite in such country. In the event that
during the Royalty Period for any country, any of InSite's Patent Rights expire
or are invalidated, or InSite is unable or elects not to obtain a patent in such
country, and generic versions of PilaSite are being sold in such country (and
such generic sales are not in contravention of any governmental, judicial or
private regulatory rules, regulations, laws, orders or judgments in effect in
such country), the royalty rate paid by B&L for sales in such country shall be
reduced to * * * of Net Sales in such country. During the Secondary Royalty
Period in any country, B&L shall pay InSite the following royalties on Net Sales
of PilaSite: (i) * * * of Net Sales of PilaSite during the first year of the
Secondary Royalty Period; (ii) * * * of Net Sales of PilaSite for the second
year of the Secondary Royalty Period; and (iii) * * * of Net Sales of PilaSite
during the third year of the Secondary Period and during any subsequent year in
which this Agreement or any extension thereof is in effect. In addition, during
the Secondary Royalty Period in any country, B&L shall pay InSite royalties of *
* * of Net Sales of the Generic (as defined below) unless B&L's sale of the
Generic was pursuant to the filing of an ANDA (as hereinafter defined) and
without any cooperation from InSite whatsoever, in which event B&L's obligation
to pay a royalty to InSite in connection with its sales of the Generic shall
exist for * * * years of the Secondary Royalty Period. Notwithstanding anything
contained herein to the contrary, B&L shall not be required to pay InSite any
royalty on Net Sales of the Generic after the end of the * * * of the Secondary
Royalty Period. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         (b) Notwithstanding anything in this Agreement to the contrary, if any
of the Patent Rights expire or are invalidated, or if InSite is unable or elects
not to obtain a patent in such country, and generic versions of PilaSite are
being sold in such country (and such generic sales are not in contravention of
any governmental, judicial or private regulatory rules, regulations, laws,
orders or judgments in effect in such country), B&L shall have the right to
manufacture, use, import, sell and distribute a generic equivalent to PilaSite
by either submitting and receiving approval of an abbreviated new drug
application, and, in countries other than the United States, an equivalent
abbreviated application ("ANDA") or obtaining from InSite the right to
supplement or amend the NDA, or foreign equivalent, to introduce a generic form
of PilaSite (the "Generic"). If B&L submits an ANDA for the Generic, it shall
notify InSite in writing at least ninety (90) days prior to the date of
submission and InSite shall cooperate with B&L in the preparation of such
submission. Alternatively, if B&L elects to submit a supplement to the NDA, or
foreign equivalent, with respect to the Generic, B&L may request from InSite,
and InSite shall grant B&L, such specific rights to the NDA, or foreign
equivalent, as are necessary to enable B&L to submit such supplement to
introduce and sell the Generic. If B&L elects to launch the Generic in any
country prior to the end of the Royalty Period in such country, in anticipation
of the entry of a third party generic competitor, the royalty due on sales of
such Generic by B&L shall be * * * of Net Sales until the end of the 

                                       5.
<PAGE>   6
Royalty Period. InSite hereby covenants not to sue B&L for patent infringement
relating to sales of the Generic which are in accordance with this Section 
3.1(b) during the Royalty Period in such country. [* INDICATES THAT MATERIAL
HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL
SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO
RULE 24b-2.]

         3.2 Sales of PilaSite between or among B&L, its Affiliates and
sublicensees shall not be subject to any royalty hereunder, and in such cases
royalties shall be calculated upon B&L or its Affiliates' or sublicensees' Net
Sales to an independent third party. B&L shall be responsible for payment of any
royalty accrued on Net Sales of PilaSite to such independent third party through
B&L's Affiliates or sublicenses. Royalties shall accrue hereunder only once in
respect of the same unit of the PilaSite.

         4. TIMING OF ROYALTY PAYMENTS; RECORDS

            4.1 Within 45 days after the end of each calendar quarter, B&L shall
pay to InSite the royalty payment due for such quarter in U.S. dollars. Such
royalty shall be converted, where applicable, from the currency of the country
in which the sale was made into U.S. dollars at the average month-end exchange
rates for such quarter as calculated based on the daily exchange rate published
in the Wall Street Journal.

            4.2 Together with each quarterly royalty payment, B&L shall submit
to InSite a written accounting showing its computation of royalties due under
this Agreement for such quarter. Said accounting shall set forth gross sales,
Net Sales, the exchange rate applied, if any, and the total royalties due for
the quarter in question.

            4.3 B&L shall keep full and accurate books and records reflecting
the sales of PilaSite and the data used in arriving at Net Sales and the amount
of royalties payable to InSite hereunder for no less than one year after the end
of each such quarter. B&L shall permit InSite, at InSite's expense, to have such
books and records examined by independent certified public accountants retained
by InSite and reasonably acceptable to B&L, during regular business hours upon
reasonable advance notice, but not later than one year following the rendering
of any such reports, accounting and payments, and no more often than one time
per year. Such independent accountants shall keep confidential (under a written
confidentiality agreement reasonably acceptable to B&L) any information obtained
during such examination and shall report to InSite only the amounts of royalties
which the independent accountant believes to be due and payable hereunder. If
such examination discloses a discrepancy of 5% or more in any amount due InSite
under this Agreement, B&L shall reimburse InSite for the out-of-pocket cost of
such examination, including any reasonable professional fees and expenses
incurred by InSite.

         5. WARRANTIES

            5.1 InSite warrants and represents that:

                  (a) it is the owner of the Patent Rights and Know-How and has
the right to license or sublicense, in the manner set forth in this Agreement,
said Patent Rights and Know-How free of any lien or encumbrance in the
Territory;


                                       6.
<PAGE>   7
                  (b) it has not assigned or conveyed any interest in the Patent
Rights or Know-How which may be inconsistent with the rights granted hereunder;

                  (c) to the best of its knowledge and after a diligent search,
the practice of the Patent Rights and Know-How in the Territory does not
infringe any rights of third parties;

                  (d) it is not aware that any third party is infringing the
Patent Rights;

                  (e) it is a corporation duly incorporated and in good standing
in its state of incorporation and has all requisite power to enter into and
perform this Agreement. Upon execution by the parties hereto, this Agreement
shall constitute a valid and legally binding obligation of InSite, enforceable
in accordance with its terms; and

                  (f) it has prosecuted all patent applications within the
Patent Rights in good faith and has no reason to believe that any patent
included within the Patent Rights would be invalid or would be held to be
unenforceable by a court of competent jurisdiction.

         6. TRANSFER AND OWNERSHIP OF KNOW-HOW; MAINTENANCE OF NDA

            6.1 As part of the license granted in Section 2, and in order to
enable B&L to develop, make, have made, use and sell PilaSite, InSite shall
provide B&L with all Know-How within thirty (30) days after signing this
Agreement. In addition, all improvements or modifications to such Know-How
generated or obtained by InSite during the Agreement Period shall be transferred
to B&L within thirty (30) days of its generation or receipt by InSite. Such
Know-How is provided to B&L subject to the confidentiality restrictions set
forth in this Agreement.

            6.2 (a) Following FDA approval of the NDA, B&L agrees to take any
and all action necessary to ensure that the NDA is maintained and all statutory
obligations associated therewith are fulfilled. To facilitate B&L's ability to
assume responsibility for maintaining the NDA, contemporaneously with the
execution of this Agreement, InSite shall execute and deliver a letter
substantially in the form of Exhibit A to this Agreement, authorizing B&L to act
on InSite's behalf as the responsible agent. Such letter shall be updated and
modified as necessary, but no less frequently than annually at the reasonable
request of B&L.

                (b) InSite hereby grants to B&L a right of reference with
respect to all information contained in the NDA, and any supplements or
amendments to such NDA. This right of reference shall include a right of
reference for purposes of Section 505(b)(2) of the FFDCA and its implementing
regulations. Contemporaneously with the execution of this Agreement, InSite
shall execute a letter substantially in the form of Exhibit B to this Agreement
(a "Right of Reference Letter").


                                       7.
<PAGE>   8
                (c) InSite hereby grants B&L the right to receive, upon written
request and at the expense of InSite, complete copies of the NDA, including any
supplements or amendments thereto, all correspondence with the FDA regarding the
NDA or PilaSite in general, all minutes of meetings held between the FDA and
InSite to discuss the NDA or PilaSite in general, all memoranda of conversations
between InSite and the FDA that relate to the NDA or PilaSite in general, and
all of InSite's Know-How. From and after the date hereof, InSite agrees that it
shall not transfer ownership of the NDA or any Know-How to any person or entity
other than B&L without the prior written consent of B&L, which consent shall not
be unreasonably withheld; provided, however, that B&L's prior written consent
shall not be required for InSite to transfer nonexclusive rights to the NDA or
Know-How to any third party for the purpose of manufacturing, marketing and
distributing PilaSite in any Major Market in which B&L no longer has an
exclusive license pursuant to the operation of Section 2.2(b) above.

                (d) B&L agrees to provide InSite with (i) fifteen (15) days'
notice prior to submission to the FDA of any routine submissions or
insignificant amendments such as minor labeling changes or minor manufacturing
changes and (ii) forty-five (45) days' notice prior to submission to the FDA of
any submission, supplement or amendment not referred to in Section 6.2(d)(i)
hereof. B&L shall provide complete copies of all proposed supplements,
submissions and amendments to InSite upon giving notice to InSite of such
proposed submission. From and after the date hereof, B&L agrees that it shall
not submit to the FDA any NDA supplement or amendment with respect to PilaSite
without the consent of InSite, which consent shall not be unreasonably withheld
and B&L may assume that InSite consents to any proposed submission that InSite
does not object to by the end of the relevant notice period. B&L further agrees
to promptly provide InSite with copies of all correspondence with and reports to
the FDA or any other agency regarding PilaSite or the NDA, all minutes of
meetings held between the FDA and B&L to discuss PilaSite or the NDA, and all
memoranda of any conversations between B&L and the FDA that relate to PilaSite
or the NDA.

         7. CONFIDENTIALITY

            7.1 InSite and B&L shall keep any Know-How or business information
provided or made available by the other party or its Affiliates hereunder
confidential, and neither InSite nor B&L shall, without the prior written
consent of the other party or its Affiliates, as the case may be, use (except as
expressly permitted by this Agreement or for the purposes of this Agreement), or
disclose to any third party, any Know-How or business information provided or
made available by the other party or its Affiliates hereunder; provided,
however, that the foregoing shall not apply to information which the party
receiving such information can establish by written documentation to (i) have
been publicly known at the time of disclosure by the other party or its
Affiliates, as the case may be, (ii) have become publicly known, without fault
on its part, subsequent to such disclosure, (iii) have been otherwise known by
it from a source (other than the other party or its agents or

                                       8.
<PAGE>   9
Affiliates), lawfully having possession of such information, or (v) have been
developed by it or its Affiliates independently of the disclosure by the other
party or its Affiliates.

         The foregoing shall not preclude the disclosure of information by
InSite or B&L:

            (a) to its legal representatives, Affiliates, consultants, outside
contractors and (if it has the right to grant the license or sublicense) its
licensees and sublicensees, under like confidentiality obligations on the part
of the recipients, or

            (b) to the extent required by law or regulation, provided that, to
the extent reasonably possible, it shall give prompt written notice of the
proposed disclosure to the other party or its Affiliates, as the case may be, so
as to allow the other party or its Affiliates, as the case may be, an
opportunity to object to such requirement and, if applicable, assure that
confidential treatment will be accorded to such information, or

            (c) to the extent that such information is reasonably required to be
disclosed for the purpose of securing necessary governmental authorization for
the clinical testing or marketing of products or for the purpose of conducting
clinical testing or marketing of products, or of prosecuting or defending
litigation.

            7.2 The terms of this Agreement shall not be disclosed by either
party to any third party (other than as provided in Subsections 7.1(a), (b) and
(c) above) or be published unless both parties expressly agree otherwise in
writing. Furthermore, neither party shall use the name of the other party or its
Affiliates without their prior written consent. However, the foregoing
restrictions shall not apply to the disclosure of information set forth in the
form of an agreed-upon press release, if any, which may be prepared in mutually
agreeable format and substance for release when this Agreement becomes
effective, or to disclosures required by law or regulation.

         8. PATENTS

            8.1 InSite shall undertake and shall bear all costs of the
prosecution and maintenance of the Patent Rights in the Territory. InSite shall
employ reasonable efforts to keep B&L fully and timely informed with respect to
the course and conduct of patent application prosecution matters within the
scope of Patent Rights.

            8.2 If InSite elects to terminate either the prosecution or
maintenance of the Patent Rights prior to the completion of normal prosecution
before the patent examiner or prior to the end of the term for maintenance, as
the case may be, it will give B&L sixty (60) days prior written notice of such
election prior to any time limit on any action due. B&L, upon receipt of such
notice, shall have the option to undertake the continuation of such prosecution
or maintenance and InSite will transfer title to B&L for such patent application
or patent.


                                       9.
<PAGE>   10
         9. ENFORCEMENT OF PATENT RIGHTS

            9.1 If either party shall become aware of any infringement or
threatened infringement of any Patent Rights, including that contained in a
notice provided under the 1984 Act by a party filing an NDA for PilaSite, then
the party having such knowledge shall give notice to the other within ten (10)
days of becoming aware of such infringement or threatened infringement.

            9.2 InSite shall have the first right but not an obligation to bring
an enforcement action or to take any other reasonable steps to defend the Patent
Rights against infringement and B&L shall in such event give all reasonable
assistance to InSite with respect to patent and legal questions. The costs of
such patent enforcement shall be borne by InSite. If InSite does not commence a
particular infringement action within ninety (90) days after it has received
notice of such infringement, B&L, after notifying InSite in writing, shall be
entitled to bring such infringement action or other appropriate action or claim
at its own expense but shall request in writing that InSite fund 50% of such
expenses. If InSite declines to pursue such action or fails to respond to B&L
within sixty (60) days after receipt of B&L's notice that it will do so, B&L
shall have the right to undertake such action and if InSite fails to fund 50% of
B&L's expenses in pursuing such action, then B&L shall be entitled to 100% of
all recoveries and B&L shall no longer be required to pay royalties to InSite
for PilaSite in the country in which such action was prosecuted. Recovery from
any settlement or judgment from any such action in the Territory either pursued
by InSite or co-funded by InSite shall go first to reimburse the expenses of the
parties and the remainder shall be shared by the parties on a 50%/50% basis.
Notwithstanding the foregoing, if the monetary recovery is less than the
out-of-pocket expenses of InSite and B&L, reimbursement shall be on a pro rata
basis, based upon cost incurred. In any event, InSite and B&L shall assist one
another and reasonably cooperate in any such litigation at the other's request
without expense to the requesting party.

            9.3 If InSite and B&L, after consultation with each other, elect not
to bring individually or jointly, or if InSite and B&L, as the case may be,
are/is not able to stop such infringing activities in any country, the
applicable royalty for such country shall be adjusted as set forth in Section 
3.1, if applicable.

         10. INDEMNIFICATION

             10.1 Indemnification of B&L. InSite shall indemnify, defend, save
and hold B&L and each of its Affiliates, officers, directors, employees and
agents harmless from and against any liability, loss, damage, cost or expense
including reasonable attorneys' fees and expenses, excluding consequential or
special damages ("Loss" or "Losses") resulting from or arising out of (a) any
material breach of any warranty hereunder or material non-fulfillment or
non-performance by InSite of any agreement, covenant or obligation of InSite
under this Agreement; (b) any actual or alleged defect in PilaSite manufactured
by B&L, other than any actual or alleged defect arising out of B&L's failure to
manufacture PilaSite in accordance with the terms of this Agreement and except
as otherwise provided in Sections 10.2 and 10.3 below; (c) FDA enforcement
action, inspection or product recalls or market withdrawals relating to
PilaSite, except where arising out of or resulting from B&L's failure to
manufacture PilaSite in 


                                      10.
<PAGE>   11
accordance with the terms of this Agreement or B&L's labeling, packaging,
promotion, distribution, or marketing of finished units of PilaSite and except
as provided in Sections 10.2 and 10.3 below; and (d) any actual or alleged
infringement or violation by the Patent Rights or Know-How of any patent, trade
secret or other proprietary right of any third party.

             10.2 Indemnification of InSite. B&L shall indemnify, defend, save
and hold InSite and each of its Affiliates, officers, directors, employees and
agents harmless from and against Loss or Losses resulting from, or arising out
of (a) a material breach of any warranty hereunder or material non-fulfillment
or non-performance by B&L of any agreement, covenant or obligation of B&L under
this Agreement; (b) any actual or alleged defect in PilaSite manufactured
hereunder arising out of B&L's failure to manufacture PilaSite in accordance
with the terms of this Agreement, including without limitation, defects due to
tampering with PilaSite during the manufacturing process; (c) B&L's acts
relating to the promotion, marketing, labeling, packaging and/or distribution of
PilaSite; and (d) FDA enforcement action, inspection, product recalls or market
withdrawals relating to PilaSite resulting from B&L's failure to manufacture
PilaSite in accordance with the terms of this Agreement or arising out of the
labeling or packaging of finished units of PilaSite.

             10.3 Joint Obligations. InSite and B&L shall equally share any
Losses, and shall jointly defend any actions related thereto, resulting from or
arising out of acts, actions, defects, product recalls or market withdrawals for
which responsibility is not specifically apportioned by Sections 10.1 and 10.2
above. Such joint obligations shall include, without limitation, product recalls
or market withdrawals due to any tampering with PilaSite after manufacture and
distribution by B&L. Any such product recalls or market withdrawals shall be
controlled and conducted by B&L.

             10.4 Survival. The provisions of this Section 10 shall survive any
termination of this Agreement.

             10.5 Indemnification Procedures. Upon the occurrence of an event
which requires indemnification under this Agreement (an "Indemnification
Event"), the indemnified party shall give prompt written notice to the
indemnifying party providing reasonable details of the nature of the event and
the basis of the indemnity claim. The indemnifying party shall then have the
right, at its expense and with counsel of its choice, to defend, contest or
otherwise protect against any such action. The indemnified party shall also have
the right, but not the obligation, to participate at its own expense in the
defense thereof with counsel of its choice. The indemnified party shall
cooperate to the extent reasonably necessary to assist the indemnifying party in
defending, contesting or otherwise protesting against any such action provided
that the reasonable out-of-pocket cost in doing so shall be paid by the
indemnifying party. If the indemnified party fails to promptly notify 


                                      11.
<PAGE>   12
the indemnifying party of the occurrence of an Indemnification Event and such
failure has a material adverse effect on the indemnifying party, the indemnified
party shall not be entitled to indemnification with respect to such
Indemnification Event. If the indemnifying party fails within thirty (30) days
after receipt of such notice (a) to notify the indemnified party of its intent
to defend, or (b) to defend, contest or otherwise protect against such suit,
action, investigation, claim or proceeding, or fails to diligently continue to
provide such defense after undertaking to do so, the indemnified party shall
have the right, upon ten (10) days' prior written notice to the indemnifying
party, to defend, settle and satisfy any such suit, action, claim, investigation
or proceeding and recover the reasonable costs of the same from the indemnifying
party.

         11. PATENT TERM EXTENSION

             Within sixty (60) days after approval of an NDA for PilaSite, and
at B&L's option, B&L shall have the right to file at its own cost and expense an
application for an extension of any United States patent falling within the
Patent Rights, and, where applicable, for extension of Patent Rights in any
other country of the Territory under similar laws permitting patent term
extension. InSite designates B&L as its agent with respect to such filing and
prosecution for patent term extension, and agrees to cooperate with B&L in
providing any information required under the relevant United States laws or
similar laws outside the United States. Such action by B&L may be undertaken in
the name of InSite, if deemed necessary or appropriate by B&L, and InSite agrees
to cooperate with B&L, and execute any documents reasonably necessary relating
to such action.

         12. TRADEMARK

             InSite shall grant B&L an exclusive license to the trademark
PilaSite; provided, however, that such license shall be nonexclusive in any
Major Market for which the general technology license granted hereunder becomes
nonexclusive pursuant to Section 2.2(b).

         13. NOTICES

and shall remain in effect until the later of the expiration of the last to
expire Patent Rights, or ten (10) years from the first commercial sale of
PilaSite in the last country in which it is commercially exploited, unless
earlier terminated as permitted hereunder. B&L shall have the right, upon 180
days written notice to InSite, to renew this Agreement for an unlimited number
of five (5) year terms (each a "Renewal Term"). B&L shall have the right to
terminate any Renewal Term only upon 180 days prior written notice to InSite.
Upon the termination of this Agreement for any reason, B&L shall have the right,

Agreement by giving notice to take effect immediately.

             14.3 B&L may terminate this Agreement and the licenses granted

                                      13.
<PAGE>   14
its Affiliates and sublicensees, as applicable, shall return to InSite all

             15. FORCE MAJEURE

                 Neither party shall be responsible or liable to the other
hereunder for failure or delay in performance of this Agreement due to any war,
fire, accident or other casualty, or any labor disturbance or act of God or the
public enemy, or any other contingency beyond such party's reasonable control.
In addition, in the event of the applicability of this Section , the party
affected by such force majeure shall use reasonable efforts, consistent with
good business judgment, to eliminate, cure and overcome any of such causes and
resume performance of its obligations.

         16. ASSIGNMENT

             This Agreement and all rights and obligation hereunder are personal
to the parties hereto, and may not be assigned without the express prior written

be void and without effect.

         17. GOVERNING LAW

performed in said State.

         18. SEVERABILITY

             If any one or more of the provisions of this Agreement shall be
held to be invalid, illegal or unenforceable, the validity, legality or
enforceability of the remaining provisions hereof shall not in any way be
affected or impaired thereby. In the event any provision shall be held invalid,
illegal or unenforceable, the parties shall use best efforts to substitute a
valid, legal and enforceable provision which, insofar as possible, implements

<PAGE>   15
         19. NO WAIVER

             The failure of any party hereto at any time or times to require

parties relating to the subject matter thereof, and no amendment or modification

         21. DISPUTE RESOLUTION

             Except that either party may seek equitable relief from a court, if
any dispute arises between InSite and B&L with respect to the interpretation or
breach of this Agreement, either party shall notify the other of the dispute in
writing and shall attempt to resolve the dispute through discussions between
INSITE'S Chief Executive Officer and B&L's President. If such officers are
unable to resolve the dispute within thirty (30) days after the date written
notice of the dispute is delivered, the parties shall seek to resolve the
dispute by initiating an Alternative Dispute Resolution ("ADR") in which the
Judicial Arbitration and Mediation Services ("JAMS"), Oakland, California shall
select the mediator. Such mediator shall hold a hearing to resolve the dispute
within sixty (60) days of his or her selection. The location of the hearing
shall be Oakland, California. Each party may be represented by counsel and shall
have the right to make a presentation of evidence at such hearing. The mediator
shall render a disposition on the proposed rulings as expeditiously as possible
but not later than fifteen (15) days after the conclusion of the hearing. If the
parties are unable to resolve the dispute, the dispute may, upon the agreement
of the parties, be settled by arbitration. If the parties agree to arbitrate the
dispute, such arbitration shall take place in Alameda County, California in
accordance with the then current commercial arbitration rules of the American
Arbitration Association and judgment upon the award rendered by the
Arbitrator(s) shall be binding on the parties and may be entered by either party
in the court or forum, state or federal, having jurisdiction. Notwithstanding
anything to the contrary, nothing in this Agreement shall be deemed as
preventing either party from seeking injunctive relief (or any other provisional
remedy) from any court having jurisdiction over the parties and the subject
matter of the dispute as necessary to protect either party's name, proprietary
information, trade secrets, know-how or any other proprietary rights. Further,
in the event the parties do not agree to arbitrate any dispute hereunder, either
party may seek such other remedy, at law or in equity, as it may deem necessary
or appropriate.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed by their duly authorized representatives as of the day and year first
above written.

faith discuss the most appropriate means of proceeding. In the event the Joint
Development Committee cannot agree upon the appropriate means of proceeding
within ten (10) days of commencing such discussions, either party may request
that InSite's Chief Executive Officer and B&L's President resolve the matter by
mutual agreement. If such officers are unable to resolve the matter within ten
(10) days, either party may terminate this Agreement upon ten (10) days written
notice. Upon such termination, all rights to Timolol, the Timolol Product and
DuraSite, including without limitation, all rights to the Patents and Know-How,

                  6. Commercial Development. Upon B&L's acceptance of the
Preclinical Model as the Clinical Candidate, B&L will use its reasonable efforts
consistent with the effort that would be expended by a similarly situated
company in light of the existing business opportunity, to proceed with (i)
completing, or arranging for the conduct and completion of, any clinical trials
required to be conducted in order to obtain approval of the NDA, including, but
not limited to, conducting all statistical analysis and preparation of any
registration summary documents required by any regulatory authority in each
country of the Territory requiring such an application as directed by the Joint
Development Committee, (ii) obtaining all Regulatory Approvals and Pricing
Approvals in the Territory as directed by the Joint Development Committee, and
(iii) following FDA approval of the NDA, manufacturing, commercialization,
marketing and sale of the Timolol Product in the Territory, and (iv) subject to
the terms and conditions of this Agreement, B&L shall use reasonable efforts to
from time to time perform Market Research deemed by B&L in its reasonable
discretion to be necessary or appropriate relating to the Timolol Product, or as
otherwise agreed and directed by the Joint Development Committee. To the extent
B&L undertakes Market Research, B&L will periodically, and in no event more than
sixty (60) days after receipt of Market Research, provide InSite with a summary
of all of the data and information collected through the Market Research, until
filings for Regulatory Approvals in the country subject to the Market Research
is made.

                  B&L shall promptly submit copies of all documentation related

exercise reasonable efforts and diligence in conducting all activities with
respect to the Timolol Product in accordance with each party's business, legal,
medical and scientific judgment and normal practices and procedures for products
with similar technical and commercial potential.

                  7. Loss of Exclusive License in Major Markets. In the event
that B&L elects not to file applications for Regulatory Approval or Pricing
Approval for the Timolol Product in any Major Market within six (6) months of
the date the Timolol Product NDA is approved by the FDA, or fails to use
reasonable efforts to cause any such applications to be approved by the
necessary regulatory authorities, or fails to maintain such approvals, upon
thirty (30) days advanced written notice by InSite, the license granted by
InSite to B&L in Section D below shall no longer be exclusive in any country in
such Major Market. In such event, the royalty paid by B&L on sales of the
Timolol Product in countries within the Major Market for which the license is no
longer exclusive shall continue to be calculated in accordance with Section D
below; provided, however, * * *. [* INDICATES THAT MATERIAL HAS BEEN

rights to use all documentation, approvals, information and data (including, but
not limited to, Market Research Summaries which shall be provided solely to the
Joint Development Committee until such time as the filing for Regulatory
Approval in the relevant country has been made) developed by B&L relating to the
Timolol Product and InSite shall have the right to fully use and cross reference
all submissions, approvals, information and data (collectively, the "Clinical
Materials").

                  9. Marketing Obligations. B&L, for itself and its Affiliates,
agrees:

                     a. unless otherwise requested by InSite and to the extent
practicable, to place on the outside of the Timolol Product packaging and on
promotional materials (in readable, non-obscured type that is of reasonable size

discrepancy discovered, all discrepancies (and interest thereon) shall be
immediately due and payable.

         D. License and Marketing Obligations.

            1. Exclusive License. Subject to the terms and conditions of this
Agreement and during the term hereof, InSite hereby grants B&L an exclusive
product license or sublicense under the Patents and unpatented Know-How to
manufacture, have manufactured, use, import, sell and sublicense the Timolol
Product in the Territory.

            2. Right to Sublicense. B&L shall make all payments to InSite on
behalf of its Affiliates and sublicensees. In addition, B&L will cause such
Affiliates or sublicensees to satisfy and honor all the obligations, limitations
and restrictions of or on B&L under this Agreement.

            3. Royalties.

               a. In consideration of the rights granted above, during the
Royalty Period in any country, B&L shall pay InSite royalties consisting of * *
* of Net Sales of the Timolol Product in such country. In the event that during
the Royalty Period for any country, any of InSite's Patents expire or are
invalidated and generic versions of the Timolol Product are being sold in such
country (and such generic sales are not in contravention of any governmental,
judicial or private regulatory rules, regulations, laws, orders or judgments in
effect in such country), the royalty rate paid by B&L shall be reduced to * * *
of Net Sales in such country. During the Secondary Royalty Period in any
country, B&L shall pay InSite the following royalties on Net Sales of the
Timolol Product: (i) * * * of Net Sales of the Timolol Product during the first
year of the Secondary Royalty Period; (ii) * * * of Net Sales of the Timolol
Product for the second year of the Secondary Royalty Period; and (iii) * * * of
Net Sales of the Timolol Product during the third year of the Secondary Period
and during any subsequent year in which this Agreement or any extension thereof
is in effect. In addition, during the Secondary Royalty Period in any country,
B&L shall pay InSite royalties of * * * of Net Sales of the Generic (as defined
below) unless B&L's sale of the Generic was pursuant to the filing of an ANDA
(as hereinafter defined) and without any cooperation from InSite whatsoever, in
which event B&L's obligation to pay a royalty of * * * shall terminate after the
passage of * * * years after the commencement of the Secondary Royalty Period.
Notwithstanding anything contained 

                                      11.
<PAGE>   12
herein to the contrary, B&L shall not be required to pay InSite any royalty on
Net Sales of the Generic after the end of the * * * year of the Secondary
Royalty Period. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

                  b. Notwithstanding anything in this Agreement to the contrary,
if any of the Patents expire or are invalidated, or if InSite is unable or
elects not to obtain a patent in such country, and generic versions of the
Timolol Product are being sold in such country (and such generic sales are not
in contravention of any governmental, judicial or private regulatory rules,
regulations, laws, orders or judgments in effect in such country), B&L shall
have the right to manufacture, use, sell and distribute a generic equivalent of
the Timolol Product by either submitting and receiving approval of an
abbreviated new drug application, and, with respect to countries other than the
United States, the equivalent abbreviated application ("ANDA") or obtaining from
InSite, if necessary, the right to supplement or amend any Regulatory Approval
to introduce a generic form of the Timolol Product (the "Generic"). If B&L
submits an ANDA for the Generic, it shall notify InSite in writing at least
ninety (90) days prior to the date of submission and InSite shall cooperate with
B&L in the preparation of such submission. Alternatively, if B&L elects to
submit a supplement to the NDA with respect to the Generic, B&L may request from
InSite, and InSite shall grant B&L, such specific rights to the Regulatory
Approval as are necessary to enable B&L to submit such supplement to introduce
and sell the Generic. If B&L elects to launch the Generic in any country prior
to the end of the Royalty Period in such country, in anticipation of the entry
of a third party generic competitor, the royalty due on sales of such Generic by
B&L shall be * * * of Net Sales until the end of the Royalty Period. InSite
hereby covenants not to sue B&L for patent infringement relating to sales of the
Generic which are in accordance with this Section D.3.1(b) during the Royalty
Period in such country. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND
CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL
HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

                  c. Sales of the Timolol Product between or among B&L, its
Affiliates and sublicensees shall not be subject to any royalty hereunder, and
in such cases royalties shall be calculated upon B&L or its Affiliates' or
sublicensees' Net Sales to an independent third party. B&L shall be responsible
for payment of any royalty accrued on Net Sales of the Timolol Product to such
independent third party through B&L's Affiliates or sublicenses. Royalties shall
accrue hereunder only once in respect of the same unit of the Timolol Product.

         4. Timing of Royalty Payments; Records.

            a. Within 45 days after the end of each calendar quarter, B&L shall
pay InSite the royalty payment due for such quarter in U.S. dollars. All royalty
payments shall be made via wire transfer of same day funds to such account as
shall be designated by InSite not

                                      12.
<PAGE>   13
later than five (5) days prior to the date such payment is due. Such royalty
shall be converted, where applicable, from the currency of the country in which
the sale was made into U.S. dollars at the average month-end exchange rate for
such quarter as calculated based on the daily exchange rates published in The
Wall Street Journal. 

            b. Together with each quarterly royalty payment, B&L shall submit to
InSite a written accounting showing its computation of royalties due under this
Agreement for such quarter. Said accounting shall set forth gross sales, Net
Sales, the exchange rate applied, if any, and the total royalties due for the
quarter in question.

            c. B&L shall keep full and accurate books and records reflecting the
sales of the Timolol Product and the data used in arriving at Net Sales and the
amount of royalties payable to InSite hereunder for no less than one year after
the end of each such quarter. B&L shall permit InSite, at InSite's expense, to
have such books and records examined by independent certified public accountants
retained by InSite and reasonably acceptable to B&L, during regular business
hours upon reasonable advance notice, but not later than one year following the
rendering of any such reports, accounting and payments, and no more often than
one time per year. Such independent accountants shall keep confidential any
information obtained during such examination and shall report to InSite only the
amounts of royalties which the independent accountant believes to be due and
payable hereunder.

         E. Ownership.

            1. Ownership. As between the parties, the parties shall have the

throughout the world) in any inventions, ideas or information made or conceived
or reduced to practice by either InSite or B&L in the course of development of
the Timolol Product hereunder which relate to the DuraSite delivery system (an
"Improvement"); and (ii) subject to the rights of InSite set forth in Section 
E.1.d., B&L shall have all right, title and interest (including all patent
rights throughout the world) in any inventions, ideas or information made or
conceived or reduced to practice by either InSite or B&L in the course of
development of the Timolol Product hereunder which relate to Timolol. B&L shall
have the right to acquire a nonexclusive license to any such Improvement on
terms reasonably agreed to by the parties.

               b. Provided, as to any inventions, ideas or proprietary
information made or conceived or reduced to practice by either party prior to
the Effective Date of this Agreement that relates directly or indirectly to the
Timolol Product ("Precollaborative Inventions"), InSite (if such
Precollaborative Invention is made, conceived or reduced to practice by B&L) or
B&L (if such Precollaborative Invention is made, conceived or reduced to
practice by InSite) shall have a paid-up, non-exclusive license to exploit such
invention, idea or information as it relates to and solely for use with the
Timolol Product and the Collaborative 

                                      13.
<PAGE>   14
Project. Provided, however, that neither party, as the case may be, shall use
such idea, invention or proprietary information for the development or
manufacture of products for any entity other than the other party or an assignee
permitted under this Agreement. Such non- exclusive license shall terminate upon
termination of this Agreement. Provided, that either party, as the case may be,
shall be free to use for any purpose, without any accounting to the other party,
any information of the types described below in Section F(i)-(iv).

               c. Provided, as to any inventions, ideas or information conceived
or reduced to practice by InSite or the parties jointly in the course of
development of the Timolol Product in connection with this Agreement which
relates to Timolol and which may be exploited in a delivery system other than

shall have a perpetual, paid-up, exclusive right to exploit (by itself or with a
third party) such invention, idea or information as it relates to Timolol for
all purposes other than delivery through the DuraSite system.

               Provided further, consistent with patent law and sound patent
practice, B&L in good faith will seek to separate from other patent applications
any applications for any invention claiming Timolol exclusive of DuraSite.
Provided, however, B&L shall not be required to take any action which would in
any way detract from, jeopardize or limit any patent application resulting from
the development of the Timolol Product under this Agreement. Provided, further,
in the event that a patent is issued the claims of which include Timolol but do
not include the DuraSite delivery system in any respect, B&L may obtain the
rights to an assignment of such patent and InSite shall facilitate such
assignment; in such case, B&L shall reimburse InSite for all costs and expenses
associated with the preparation and prosecution of such patent application.

               d. Provided, as to any inventions, ideas or information conceived
or reduced to practice by B&L or the parties jointly in the course of
development of the Timolol Product in connection with this Agreement which
relates to the DuraSite delivery system, InSite shall have a perpetual, paid up
exclusive right to exploit (by itself or with a third party) such invention,
idea or information as it relates to the DuraSite delivery system.

               Provided further, consistent with patent law and sound patent
practice, InSite in good faith will seek to separate from other patent
applications any applications for any invention relating to the DuraSite
delivery system. Provided, however, InSite shall not be required to take any
action which would in any way detract from, jeopardize or limit any patent
application resulting from the development of the Timolol Product under this
Agreement. Provided, further, in the event that a patent is issued the claims of
which include the DuraSite delivery system, but do not include other delivery
systems in any respect, InSite may obtain the rights to an assignment of such
patent and B&L shall facilitate such assignment; in such case, InSite shall
reimburse B&L for all costs and expenses associated with the preparation and
prosecution of such patent application.


                                      14.
<PAGE>   15
                    e. Provided, as to any Joint Invention relating in whole or
in part to the DuraSite delivery system (with or without Timolol), InSite shall
have a perpetual, paid up exclusive right to exploit (by itself or with a third
party) such Joint Invention, idea or information as it relates to the DuraSite
delivery system (with or without Timolol).

               2. Assignments. B&L and InSite hereby agree to make any
assignments necessary to accomplish the foregoing ownership provisions. In
addition, each party will have the exclusive right to, and, at its expense, the
other party agrees to assist in every proper way (including, without limitation,
becoming a nominal party) to evidence, record and perfect any such assignments
and to apply for and obtain recordation of and from time to time enforce,
maintain, and defend such proprietary right.

         F. Confidentiality. InSite and B&L shall keep any Proprietary
Information or other business information provided or made available by the
other party or its Affiliates hereunder confidential, and neither InSite nor B&L
shall, without the prior written consent of the other party or its Affiliates,
as the case may be, use (except as expressly permitted by this Agreement or for
the purposes of this Agreement), or disclose to any third party, any Proprietary
Information or other business information provided or made available by the
other party or its Affiliates hereunder; provided, however, that the foregoing
shall not apply to information which the party receiving such information can
establish by written documentation to (i) have been publicly known at the time
of disclosure by the other party or its Affiliates, as the case may be, (ii)
have become publicly known, without fault on its part, subsequent to such
disclosure, (iii) have been otherwise known by it from a source (other than the
other party or its agents or Affiliates), lawfully having possession of such
information, or (iv) have been developed by it or its Affiliates independently
of the disclosure by the other party or its Affiliates.

               The foregoing shall not preclude the disclosure of Proprietary
Information or other business information by InSite or B&L:

                    a. to its legal representatives, Affiliates, consultants,
outside contractors and (if it has the right to grant the license or sublicense)
its licensees and sublicensees, under like confidentiality obligations on the
part of the recipients, or

                    b. to the extent required by law or regulation, provided
that, to the extent reasonably possible, it shall give prompt written notice of
the proposed disclosure to the other party or its Affiliates, as the case may
be, so as to allow the other party or its Affiliates, as the case may be, an
opportunity to object to such requirement and, if applicable, assure that
confidential treatment will be accorded to such information, or

                    c. to the extent that such information is reasonably
required to be disclosed for the purpose of securing Regulatory Approval or
Payment Approval or other necessary governmental authorization for the clinical
testing or marketing of the Timolol Product or of prosecuting or defending
litigation.


                                      15.
<PAGE>   16
               Notwithstanding the foregoing, all Proprietary Information
related to a matter assigned to a party hereunder pursuant to Section E shall be
deemed Proprietary Information of the assignee and exceptions (i) through (iv)
set forth above will not be applicable thereto.

         G. Limited Liability.

            1. Incidental and Consequential Damages. NEITHER PARTY WILL BE
LIABLE UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER THEORY FOR ANY
INCIDENTAL OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY SUBJECT MATTER OF THIS
AGREEMENT.

            2. Limited Liability. NEITHER PARTY WILL BE LIABLE WITH RESPECT TO
ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE, STRICT
LIABILITY OR OTHER THEORY FOR COST OF PROCUREMENT OF SUBSTITUTE GOODS, SERVICES,
TECHNOLOGY OR RIGHTS OR FOR ANY AMOUNTS AGGREGATING IN EXCESS OF AMOUNTS PAID TO
IT HEREUNDER.

         H. Term and Termination.

            1. Term. Unless terminated earlier as provided below or elsewhere in
this Agreement, this Agreement shall have a term extending from the Effective
Date to the later of: (i) the expiration of the last Patent, or (ii) ten (10)
years from the date the Timolol Product was first commercially sold in the last
country in which it is commercially exploited. Provided, that B&L shall have the
right upon 180 days written notice to InSite, to renew the provisions of this
Agreement relating to the license granted hereunder, and the payment of
royalties therefor, for an unlimited number of five (5) year terms (each a
"Renewal Term"). B&L shall have the right to terminate any Renewal Term upon 180
days prior written notice to InSite.

            2. Termination by Either Party for Cause. This Agreement may be
terminated by either party for cause immediately upon the occurrence of any of
the following events:

               a. If the other ceases to do business, or otherwise terminates
its business operations;

               b. If the other shall fail to promptly secure or renew any
license, registration, permit, authorization or approval which materially
affects the conduct of its business in the manner contemplated by this Agreement
in any Major Market Country or if any such license, registration, permit,
authorization or approval is revoked or suspended and not reinstated within
sixty (60) days (or if the applicable authority revoking or suspending such
license, registration, permit, authorization or approval does not, in its
ordinary course, reinstate such license, registration, permit, authorization or
approval within sixty (60) days, then the party shall exercise its diligent
efforts to have such license, registration, permit, authorization or approval

                                      16.
<PAGE>   17
reinstated, and so long as such party is diligently pursuing reinstatement of
such license, registration, permit, authorization or approval, and it can
reasonably be assumed that such license, registration, permit, authorization or
approval will be reinstated in due course, then such failure to obtain
reinstatement will not be grounds for termination of this Agreement (this clause
applies solely on a country-by-country basis);

               c. If the other materially breaches any material provision of
this Agreement and fails to cure such breach within sixty (60) days (twenty (20)
days in the case of a failure to pay any amounts due hereunder) of notice
describing the breach, provided, however, that if such a cure can be achieved
and the breaching party is diligently pursuing a cure, then such a breach shall
not be grounds for termination of this Agreement; or

               d. If the other shall seek protection under any bankruptcy,
receivership, trust deed, creditors arrangement, or comparable proceeding, or if
any such proceeding is instituted against the other (and not dismissed within
one hundred and twenty (120) days).

         3. Termination by Either Party for Other Reasons.

            a. In the event that either party hereto assigns any part of this
Agreement, by operation of law or otherwise, except as specifically permitted
under this Agreement, it shall notify the other party hereto at least thirty
(30) days prior to such assignment, and the other party shall have thirty (30)
days from the date of such notice to terminate this Agreement, effective
immediately upon receipt of such notice. Failure to give such notice within such
thirty (30) day period shall be deemed to be a waiver of such party's
termination right under this Section H.3. with respect to such assignment.

            b. B&L shall have the right to terminate this Agreement if, in the
reasonable discretion of B&L, the results of Phase II clinical testing of the
Timolol Product indicate that the FDA is unlikely to eventually approve the
Timolol Product for marketing and sale in the United States. In the event B&L
terminates this Agreement pursuant to this Section H.3.b., all rights to the
Timolol Product shall revert to InSite and Insite shall be free to fully
exploit, without approval or accounting, all of the information developed
hereunder with respect to the Timolol Product.

         4. Effect of Termination. The following provisions shall survive the
termination of this Agreement, and any extensions thereof: Sections D.3 (to the
extent inventories of the Timolol Product in existence upon the date of
termination are sold in any country after termination of this Agreement), E, F,
H.4., I, and K.4, K.6, K.7, K.8, K.9 and K.13. Remedies for breaches will also
survive. Each party will promptly return all Proprietary Information of the
other (and all copies and abstracts thereof) that it is not entitled to use
under the surviving terms of this Agreement. Termination of this Agreement with
respect to the Timolol Product in a particular country shall have the same
effect as termination of this entire Agreement, but with respect to such country
only.


                                      17.
<PAGE>   18
               5. Termination Not Sole Remedy. Termination is not the sole
remedy under this Agreement and, whether or not termination is effected, all
other remedies will remain available.

         I. Indemnity.

            1. Joint Indemnification Obligations. Each party shall defend,
indemnify and hold the other party, any Affiliate of the other party, any
officer, director or employee of such other party or of any of its Affiliates
(individually, an "Exculpated Party") harmless from and against any claim,
action, damage, loss, liability or expense (including, without limitation,
reasonable attorneys' fees, settlement costs, litigation costs and costs on
appeal regardless of outcome) ("Claims") incurred or suffered by any Exculpated
Party due to: (a) the material breach of any covenant or agreement by such
party; (b) any material misrepresentation or breach of warranty made by such
party pursuant to this Agreement; (c) any claim arising from the gross
negligence or intentional misconduct of such party; or (d) the operations or
activities of such party's Affiliates, licensees or sublicensees in material
contravention of the requirements of this Agreement (and such party shall
terminate immediately any such sublicense where a breach of its obligations by a
sublicensee cannot be readily compensated through monetary damages). In
addition, B&L and InSite each specifically acknowledge and shall comply with
their respective indemnification obligations set forth in that certain
Manufacturing and Supply Agreement between B&L and InSite of even date herewith,
which indemnification obligations are hereby incorporated by reference herein.

            2. Patent Indemnity. InSite shall defend and hold B&L and its
officers, directors, agents and employees harmless from any claim or liability
resulting from infringement by DuraSite of any United States patent issued as of
the date of approval of the Timolol Product by the FDA for sale in the United
States or, if no FDA approval is required, upon Commercial Launch in the United
States, provided InSite is promptly notified in writing of any and all threats,
claims and proceedings related thereto. InSite and B&L shall confer promptly (in
no event more than five (5) days after receipt by either party of such threat,
claim or proceeding) to discuss any such threats, claims or proceedings. InSite
shall have the exclusive authority to evaluate, defend and settle such patent
claim or litigation. After such discussions, InSite at its own expense and
option may then (i) settle or defend such claim, (ii) procure for B&L the right
to sell the Timolol Product, (iii) modify the Timolol Product to avoid
infringement, (iv) request B&L to cease further sale of the Timolol Product, or
(v) do any combination of the above. B&L shall provide InSite with assistance
and all relevant information necessary to pursue any such action.

            3. Notice of Claim for Indemnification. The indemnities of Sections 
I.1 and I.2 above shall not apply (i) if the indemnified party fails to give the
indemnifying party prompt notice of any Claim it receives and such failure
materially prejudices the indemnifying party, or (ii) unless the indemnifying
party is given the opportunity to approve any settlement, which approval shall
not be unreasonably withheld. Furthermore, the indemnifying party shall not be
liable for attorneys' fees or expenses of litigation of the indemnified party
unless the indemnified 

                                      18.
<PAGE>   19
party gives the indemnifying party the opportunity to assume control of the
defense or settlement. In addition, if the indemnifying party assumes such
control, it shall only be responsible for the legal fees and litigation expenses
of the attorneys it designates to assume control of the litigation. However, in
no event shall the indemnifying party assume control of the defense of the
indemnified party without the consent of the indemnified party (which consent
shall be given or not at its sole discretion).

         J. Maintenance and Enforcement of Patents.

            1. Maintenance and Enforcement. InSite shall undertake and shall
bear all costs of the prosecution and maintenance of the Patents in the
Territory. InSite shall employ reasonable efforts to keep B&L fully and timely
informed with respect to the course and conduct of patent application
prosecution matters within the scope of the Patents.

            2. Termination of Prosecution or Maintenance. If InSite elects to
terminate either the prosecution or maintenance of any of the Patents prior to
the completion of normal prosecution before the patent examiner or prior to the
end of the term for maintenance, as the case may be, it will give B&L sixty (60)
days prior written notice of such election prior to any time limit on any action
due. B&L, upon receipt of such notice, shall have the option to undertake the
continuation of such prosecution or maintenance and InSite will transfer title
to B&L for such patent application or patent.

            3. Infringement of Patents.

                a. If either party shall become aware of any infringement or
threatened infringement of any Patents, including that contained in a notice
provided under the 1984 Act, then the party having such knowledge shall give
notice to the other within ten (10) days of becoming aware of such infringement
or threatened infringement.

                b. InSite shall have the first right but not an obligation to
bring an enforcement action or to take any other reasonable steps to defend the
Patents against infringement and B&L shall in such event give all reasonable
assistance to InSite with respect to patent and legal questions. The costs of
such patent enforcement shall be borne by InSite. If InSite does not commence a
particular infringement action within ninety (90) days after it has received
notice of such infringement, B&L, after notifying InSite in writing, shall be
entitled to bring such infringement action or other appropriate action or claim
at its own expense but shall request in writing that InSite fund 50% of such
expenses. If InSite declines to pursue such action or fails to respond to B&L
within sixty (60) days after receipt of B&L's notice that it will do so, B&L
shall have the right to undertake such action and if InSite fails to fund 50% of
B&L's expenses in pursuing such action, then B&L shall be entitled to 100% of
all recoveries and B&L shall no longer be required to pay royalties to InSite
for the Timolol Product in the country in which such action was prosecuted.
Recovery from any settlement or judgement from any such action in the Territory
either pursued by InSite or co-funded by InSite shall go first to reimburse the
expenses of the parties and the remainder shall be shared by the parties on a



                                      19.
<PAGE>   20
50%/50% basis. Notwithstanding the foregoing, if the monetary recovery is less
than the out-of-pocket expenses of InSite and B&L, reimbursement shall be on a
pro rata basis, based upon cost incurred. In any event, InSite and B&L shall
assist one another and reasonably cooperate in any such litigation at the
other's request without expense to the requesting party.

                c. If InSite and B&L, after consultation with each other, elect
not to bring suit, individually or jointly, or if InSite and B&L, as the case
may be, are/is not able to stop such infringing activities in any country, the
applicable royalty for such country shall be adjusted as set forth in Section 
B.4.a, if at all.

         K. General.

            1. Amendment and Waiver. Except as otherwise expressly provided
herein, any provision of this Agreement may be amended and the observance of any
provision of this Agreement may be waived (either generally or in any particular
instance and either retroactively or prospectively) only with the written
consent of the parties. However, it is the intention of the parties that this
Agreement be controlling over additional or different terms of any purchase
order, confirmation, invoice or similar document, even if accepted in writing by
both parties, and that waivers and amendments shall be effective only if made by
non-pre-printed agreements clearly understood by both parties to be an amendment
or waiver. The failure of either party to enforce its rights under this
Agreement at any time for any period shall not be construed as a waiver of such
rights.

            2. Dispute Resolution. Except that either party may seek equitable
relief from a court, if any dispute arises between InSite and B&L with respect
to the interpretation or breach of this Agreement, either party shall notify the
other of the dispute in writing and shall attempt to resolve the dispute through
discussions between InSite's Chief Executive Officer and B&L's President. If
such officers are unable to resolve the dispute within thirty (30) days after
the date written notice of the dispute is delivered, the parties shall seek to
resolve the dispute by initiating an Alternative Dispute Resolution ("ADR") in
which the Judicial Arbitration and Mediation Services ("JAMS"), Oakland,
California shall select the mediator. Such mediator shall hold a hearing to
resolve the dispute within sixty (60) days of his or her selection. The location
of the hearing shall be Oakland, California. Each party may be represented by
counsel and shall have the right to make a presentation of evidence at such
hearing. The mediator shall render a disposition on the proposed rulings as
expeditiously as possible but not later than fifteen (15) days after the
conclusion of the hearing. If the parties are unable to resolve the dispute, the
dispute may, upon the agreement of the parties, be settled by arbitration. If
the parties agree to arbitrate the dispute, such arbitration shall take place in
Alameda County, California in accordance with the then current commercial
arbitration rules of the American Arbitration Association and judgment upon the
award rendered by the Arbitrator(s) shall be binding on the parties and may be
entered by either party in the court or forum, state or federal, having
jurisdiction. Notwithstanding anything to the contrary nothing in this Agreement
shall be deemed as preventing either party from seeking injunctive relief (or
any other provisional remedy) from any court having jurisdiction over the
parties and the subject matter of the dispute

                                      20.
<PAGE>   21
as necessary to protect either party's name, proprietary information, trade
secrets, know-how or any other proprietary rights. Further, in the event the
parties do not agree to arbitrate any dispute hereunder, either party may seek
such other remedy, at law or in equity, as it may deem necessary or appropriate.

         3. Governing Law; Attorneys' Fees; Legal Actions. This Agreement shall
be governed by and construed under the laws of the State of California without
regard to conflicts of laws provisions thereof. In any action or proceeding to
enforce rights under this Agreement, including without limitation, any
arbitration, the prevailing party shall be entitled to recover costs and
attorneys' fees.

         4. Headings. Headings and captions are for convenience only and are not
to be used in the interpretation of this Agreement.

         5. Notices. Any and all notices or other communications required or
permitted under this Agreement must be in written form by facsimile
transmission, or mailed postage prepaid by first class certified or registered
mail, or sent by a nationally recognized express courier service or hand
delivered, and shall be deemed to have been made three (3) days after the date
of mailing, or on the next business day if sent by express courier service or on
the date of delivery or transmission if hand delivered or sent by facsimile to
the address set forth below or to such other address as either party may from
time to time specify in a notice to the other in the manner herein provided.

         6. Entire Agreement. This Agreement supersedes all proposals, oral or
written, all negotiations, conversations, or discussions between or among
parties relating to the subject matter of this Agreement and all past dealing or
industry custom.

         7. Severability. If any provision of this Agreement is held to be
illegal or unenforceable, that provision shall be limited or eliminated to the
minimum extent necessary so that this Agreement shall otherwise remain in full
force and effect and enforceable.

         8. Relationship of Parties. The parties hereto expressly understand and
agree that the other is an independent contractor in the performance of each and
every part of this Agreement, and is solely responsible for all of its employees
and agents and its labor costs and expenses arising in connection therewith.
Nothing in this Agreement shall be construed to give either party the power or
authority to act for, bind or commit the other party.

         9. Assignment. This Agreement and the rights hereunder are not
transferable or assignable, except as specifically permitted in this Agreement,
without the prior written consent of the parties hereto, except for rights to
payment and except to a person or entity who acquires all or substantially all
of the assets, capital stock or business of a party, whether by sale, merger or
otherwise.

         10. Publicity, Press Releases and Terms of Agreement. Except to the
extent necessary under applicable laws or for ordinary marketing purposes, the
parties agree that (i) no press releases or other publicity relating to the
substance of the matters contained herein will be made without joint approval,
and (ii) the terms of this Agreement shall be treated by each party as
Proprietary Information. A press release announcing this Agreement will be
jointly developed and released by the parties.

         11. Force Majeure. No liability or loss of rights hereunder shall
result to either party from delay or failure in performance (other than payment)
caused by force majeure, that is, circumstances beyond the reasonable control of
the party affected thereby, including, without limitation, acts of God, fire,
flood, war, government action, compliance with laws or regulations, strikes,
lockouts or other serious labor disputes, or shortage of or inability to obtain
material or equipment.

         12. Remedies. Except as otherwise expressly stated in this Agreement,
the rights and remedies of a party set forth herein with respect to failure of
the other to comply with 

                                      22.
<PAGE>   23
the terms of this Agreement (including, without limitation, rights of full
termination of this Agreement) are not exclusive, the exercise thereof shall not
constitute an election of remedies and the aggrieved party shall in all events
be entitled to seek whatever additional remedies may be available in law or in
equity.

                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT is entered into as of July 18, 1996 (the
"Effective Date"), by and between InSite Vision Incorporated, a Delaware
corporation (the "Company"), and Bausch & Lomb Pharmaceuticals, Inc., a Delaware
corporation (the "Investor").

         A. The Company and Investor have entered into the following agreements
of even date herewith: (i) Timolol Development Agreement, (ii) PilaSite License
Agreement, and (iii) Contract Manufacturing Agreement (collectively the
"Ancillary Agreements"), pursuant to which the Company and Investor have
provided for the development and manufacture of products for the treatment of
various ophthalmic conditions;

         B. In connection with the execution and delivery of the Ancillary
Agreements, the Investor desires to purchase, and the Company desires to sell,
shares of the Company's Common Stock (the "Common Stock") upon the terms and
conditions hereinafter described.

         In consideration of the mutual covenants and conditions contained
herein, the parties agree as follows:

         1. Purchase and Sale of Shares.

            1.1 Sale and Issuance of Shares.

                (a) First Closing. The First Closing shall take place on the
date designated in writing by Investor to the Company not later than 3:00 P.M.
E.S.T. on the business day immediately preceding the First Closing Date, which
date shall not be sooner than the sixth business day following the Effective
Date nor later than the Twenty-fifth business day following the Effective Date.
Subject to the terms and conditions of this Agreement, Investor agrees to
purchase at the First Closing and the Company agrees to sell and issue to the
Investor at the First Closing, for a purchase price of $1,000,000 (the "First
Purchase Price"), that number of shares of Common Stock (the "First Closing
Shares" and together with the Second Closing Shares as defined below, the
"Shares") as is determined by dividing $1,000,000 by the closing price (or in
the event there is no such closing price, the average of the bid and ask price)
per share for the Common Stock as quoted on the Nasdaq National Market System,
or such national securities exchange or over-the-counter trading system on which
the Common Stock is traded at such time, on the business day immediately
preceding the First Closing Date.

                (b) Second Closing. The Second Closing shall take place on the
first anniversary of the First Closing Date. Subject to the terms and conditions
of this Agreement, Investor agrees to purchase at the Second Closing and the
Company agrees to sell and issue to the Investor at the Second Closing, for a
purchase price of $1,000,000 (the 
<PAGE>   2
"Second Purchase Price"), that number of shares of Common Stock (the "Second
Closing Shares") as is determined by dividing $1,000,000 by the closing price
(or in the event there is no such closing price, the average of the bid and ask
price) per share for the Common Stock as quoted on the Nasdaq National Market
System, or such national securities exchange or over-the-counter trading system
on which the Common Stock is traded at such time, for the business day
immediately preceding the date of the second closing (the "Second Closing
Date").

                1.2 Closing. The consummation of the purchase and sale of the
Shares shall take place at the offices of Brobeck, Phleger & Harrison LLP, 2200
Geng Road, Palo Alto, CA 94303 at 10:00 a.m. (Pacific Time), on the First and
Second Closing Dates respectively, or at such other time and place as the
Company and the Investor mutually agree upon orally or in writing. At each
Closing, Investor will make payment for the First Closing Shares or Second
Closing Shares, respectively, by wire transfer payable to the Company in the
amount of the First Purchase Price and the Second Purchase Price, respectively.
The Company shall deliver to the Investor a certificate representing the First
Closing Shares or the Second Closing Shares, respectively, within three (3)
business days of the date of each respective closing; provided, however, that
until delivery of such certificates, Investor shall have all the rights and
incidence of ownership of the First Closing Shares or Second Closing Shares, as
the case may be, as if such certificates were issued on each respective closing
date.

         2. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Investor that, except as set forth on a Schedule
of Exceptions attached hereto as Exhibit A, specifically identifying the
relevant subparagraph hereof, which exceptions shall be deemed to be
representations and warranties as if made hereunder:

             2.1 Organization; Good Standing; Qualification. The Company is a
corporation duly organized, validly existing, and in good standing under the
laws of the State of Delaware, has all requisite corporate power and authority

therefor.

             2.5 Litigation. There is no action, suit, proceeding or

any provision of federal or state statute, rule or regulation applicable to the
Company. The execution, delivery and performance by the Company of this
Agreement and the consummation of the transactions contemplated hereby will not
result in any such violation or be in conflict with or constitute, with or
without the passage of time and giving of notice, either a default under any
such provision, instrument, judgment, order, writ, decree or contract or an
event which results in the creation of any lien, charge or encumbrance upon any
assets of the Company or the suspension, revocation, 


                                       3.

under which they were made, not misleading.

             2.8 Disclosure. This Agreement and the Schedules and Exhibits
hereto do not contain any untrue statement of material fact or omit to state a

misleading in light of the circumstances under which they were made.

         3. Representations and Warranties of the Investor. The Investor hereby
represents and warrants to the Company that:

            3.1 Authorization. This Agreement constitutes its valid and legally
binding obligation, enforceable in accordance with its terms and that Investor
has full power and authority to enter into this Agreement.

            3.2 Organization. The Investor is a corporation duly organized and
validly existing and in good standing under the laws of Delaware, with all
requisite power and authority to own its properties and conduct its business as
now being conducted.

            3.3 Purchase Entirely for Own Account. This Agreement is made with
the Investor in reliance upon Investor's representations to the Company, which
by Investor's execution of this Agreement it hereby confirms, that the Shares to
be received by Investor will be acquired for investment for Investor's own
account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and that Investor has no present intention of
selling, granting any participation in, or otherwise distributing the same.
Investor does not have any contract, undertaking, agreement or arrangement with
any person to sell, transfer or grant participations to such person or to any
third person, with respect to any of the Shares.


                                       4.
<PAGE>   5
            3.4 Disclosure of Information. Investor acknowledges that it has
received all the information it has requested or, based upon the Company's
representations herein contained, considers necessary or appropriate for
deciding whether to purchase the Shares. Investor further represents that it has
had an opportunity to ask questions and receive answers from the Company
regarding the Company and the terms and conditions of the offering of the Shares
and to obtain any additional information necessary to verify the accuracy of the
information given to Investor.

            3.5 Restricted Securities. Investor understands that the Shares are
"restricted securities" under the Act as they are being acquired from the
Company in a transaction not involving a public offering and that under the Act
and the rules and regulations thereunder such securities may be resold without
registration under the Act, only in certain limited circumstances. In this
connection, the Investor represents that it is familiar with Rule 144
promulgated under the Act, as presently in effect, and understands the resale
limitations imposed thereby and by the Act.

            3.6 Accredited Investor. Investor is an "accredited investor" within
the meaning of paragraph (a) of Rule 501 of Regulation D promulgated under the
Act and was not organized for the specific purpose of acquiring the Shares.
Investor has sufficient knowledge and experience to analyze the Company so as to
be able to evaluate the risks and merits of its investment in the Company and is
financially able to bear the risks thereof.

            3.7 Further Limitations on Disposition. Without in any way limiting
the representations set forth above, the Investor further agrees not to make any
disposition of all or any portion of the Shares unless:

                (a) the disposition is made as part of a firmly underwritten
public offering of the Company's Common Stock; or

                (b) Except where the disposition is made pursuant to Rule 144
under the Act, until the transferee has agreed in writing for the benefit of the
Company to be bound by this Section 3 and Section 7 hereof, and the (i) Investor
shall have notified the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances surrounding
the proposed disposition, and (ii) if reasonably requested by the Company, the
Investor shall have furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will be exempt from the
registration requirements of Section 5 of the Act. It is agreed that the
Company's own legal counsel will provide any opinions of counsel necessary to
consummate any transactions made pursuant to Rule 144 or any state securities
laws.

             3.8 Legends. It is understood that the certificates evidencing the
Shares may bear one or all of the following legends:

                                       5.
<PAGE>   6
                 (a) "These securities have not been registered under the
Securities Act of 1933, as amended, or any State Securities law and such
securities may not be sold, offered for sale, pledged or hypothecated in the
absence of a registration statement in effect with respect to the securities
under such Act or an opinion of counsel satisfactory to the Company that such
registration is not required or unless sold pursuant to Rule 144 of such Act."

                 (b) Any legend required by the laws of the State of Florida or
Delaware or any other applicable state securities law.

             3.9 Compliance with Law. Investor is not a party to any agreement
or instrument, or subject to any charter or other corporate restriction or, to
its actual knowledge, any judgment, order, decree, law, ordinance, regulation or
other governmental restriction which would prevent or impede, or be breached or
violated by, the transactions contemplated in this Agreement.

         4. Florida Commissioner of Corporations. The Shares have not been
registered under the Securities Act of 1933, as amended, or the securities or
blue sky laws of any state, including the State of Florida, and may not be
transferred or resold without (a) registration under the Securities Act and
applicable state registration or qualifications, unless in the opinion of
counsel to the Company an exemption from registration under applicable federal
and state securities laws is then available and (b) compliance with all other
restrictions on transfer contained in this Agreement and applicable laws.

         5. Conditions of Investor's Obligations at First Closing and Second
Closing. The obligation of the Investor to purchase and pay for the Shares to be
purchased at each of the First Closing and Second Closing, as the case may be,

         7. Covenants of the Investor.

             7.1 Standstill Provisions. Commencing as of the First Closing and
for a period of five (5) years thereafter, Investor (including all Affiliates or
agents of Investor) shall not acquire beneficial ownership of any shares of
Common Stock, any securities convertible into or exchangeable for Common Stock,
or any other right to acquire Common Stock, except by way of stock dividends or
other distributions or offerings made available to holders of Common Stock
generally, from the Company or any other person or entity, without the prior
written consent of the Company, which consent may be withheld in the Company's
sole discretion, if such acquisition should cause Investor (including all
Affiliates of Investor) to beneficially own more than 9.99% of the Company's
outstanding voting stock (assuming the full conversion and exercise of all
convertible or exercisable securities of the Company); provided, however, that
in no event shall any reduction in the outstanding shares of the Company's
capital stock (or rights or options), cause a violation of this Section 7.1; and
provided further that the foregoing prohibition and requirement for consent will
not apply in the event a third party acquires more than 9.99% of the Company's
outstanding voting stock (assuming the full conversion and exercise of all
convertible or exercisable securities of the Company) either (i) in a
transaction or series of transactions to which the Company's Board of Directors
does not consent, or (ii) such third party, upon such acquisition, indicates in
a filing with the Securities and Exchange Commission ("SEC") an intent to
acquire control of the Company.

             7.2 Transfer Restriction. Investor hereby agrees that during the
time periods (i) commencing as of the First Closing and ending six (6) months
following the Second Closing; and (ii) commencing again as of such date or dates
that any registration statement registering shares of the Company in an
underwritten public offering is filed with the SEC under the Act and ending
ninety (90) days after such registration statement is declared effective by the
SEC, if the underwriter or underwriters in such offering request that all the
Company's stockholders holding at least the number of shares held by the
Investor execute a "lock-up agreement" as a condition precedent to such
offering, neither it nor any Affiliate shall, directly or indirectly, sell,
offer to sell, contract to sell (including, without limitation, any short sale),
grant any option to purchase or otherwise transfer or 

                                       8.
<PAGE>   9
dispose of (other than to donees who agree to be similarly bound) any of the
Shares, except any of the Shares which are included in any such registration
statement; provided, however, that the above transfer restrictions shall not
preclude Investor or its Affiliates from selling the Shares in any tender offer
commenced after the First Closing. In order to enforce the foregoing covenant,
the Company may impose stop-transfer instructions with respect to the Shares
held by the Investor or any Affiliate (and the Shares of every other person
subject to the foregoing restriction) until such time as Investor and any donee
bound by the terms of this Agreement have disposed of all Shares or all Shares
have been registered under the Act. For purposes of Sections 7.1 and 7.2, the
term "Affiliate" shall mean all corporations or business entities which directly
or indirectly are controlled by, control, or are under common control with
Investor.

             7.3 Voting Agreement. Investor agrees that it shall, so long as it
holds shares of Common Stock, vote such shares with respect to any proposed
merger or combination or sale of all or substantially all of the assets of the
Company, with or to any other entity in the same proportion as the shares voted
in favor of such transaction by other parties who are not themselves a party to
any such merger, combination or asset sale; provided, however, that the
foregoing voting requirement shall not apply to Investor in any transaction
which is not approved by the Company's Board of Directors or in the event of a
proposed merger or combination or sale of substantially all of the assets of the
Company to a competitor of Investor.

         8. Covenants of the Company.

             8.1 Trading Market; Reports. The Company shall ensure that its
Common Stock is listed and eligible for trading on the Nasdaq Stock Market or a
national securities exchange until such time as the Investor has resold all of
the Shares purchased hereunder. In the event the Company breaches the terms of
this Section 8.1 and, but for such breach, the Investor would be able to sell
the Shares pursuant to Rule 144 under the Securities Act of 1933, as amended
(the "Act") and the terms of Section 7.2 hereof, * * * [* INDICATES THAT
MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED
THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE
COMMISSION PURSUANT TO RULE 24b-2.]

         8.2 Registration Rights.

             (a) In the event that upon the later to occur of (i) the first

commercial sale of PilaSite in the United States; or (ii) the second anniversary
of the First Closing, the Investor cannot sell, or otherwise transfer the
Shares, after exercising diligent efforts for six (6) months, pursuant to Rule
144 promulgated under the Act and a similar exemption under applicable state
securities laws, the Investor shall have the right (y) to require the Company,
at the Company's expense (with the exception of any legal or advisory
fees or expenses incurred by the Investor in connection with such registration),
to register 

                                       9.
<PAGE>   10
the Shares and any securities issued to the Investor by way of a stock split,
dividend or any other distribution with respect to or in exchange for, or in
replacement of, the Shares (collectively, the "Registrable Securities") under
the Act and (z) to piggyback the registration of the Registrable Securities on a
registration statement otherwise filed by the Company, as provided herein.

             (b) If the Investor exercises its registration rights set forth in
Section 8.2(a)(y), the Company shall prepare and file with the Securities and
Exchange Commission ("SEC") not later than sixty (60) days following notice of
such exercise a registration statement on an appropriate form (the "Registration
Statement") for registration under the Act of the resale of the Registrable
Securities and shall take all reasonable steps necessary to have such
Registration Statement declared effective. The Investor shall furnish the
Company with all information reasonably requested by the Company (including, for
example, information regarding the Investor's intended method of disposition of
the Registrable Securities) for inclusion in the Registration Statement and
response to SEC comments thereon. The Company shall use its best efforts to
qualify the Registrable Securities under the state securities or "Blue Sky" laws
of such jurisdictions as the Investor shall reasonably request. The Company
shall use its best efforts to have the Registration Statement declared
effective, and, upon such effectiveness, shall maintain the effectiveness of the
Registration Statement, until the earlier of (i) date on which all Registrable
Securities have been resold pursuant to the Registration Statement; or (ii) such
time as the Registrable Securities may be resold without restriction pursuant to
Rule 144 under the Act.

             (c) If (but without any obligation to do so) the Company proposes
to register any of its stock or other securities under the Act in connection
with the public offering of such securities solely for cash (other than a
registration relating solely to the sale of securities to participants in a
company stock plan, a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities or
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered),
the Company shall, at such time, promptly give Investor notice of such
registration. Upon the written request of Investor given within ten (10) days of
the mailing of such notice and the entering into by the Investor of an
Underwriting Agreement with the underwriter for such offering covering all
Registrable Securities, the Company shall include in the Company's registration
statement under the Act all of the Registrable Securities that Investor has
requested to be registered; provided, however, that nothing in this Section 8.2
shall prevent the Company from at any time abandoning or delaying any such
registration without any obligation to Investor and provided, further, however,
that if the underwriter advises the Company that marketing factors require a
limitation on the number of shares to be underwritten, the underwriter may
exclude all Registrable Securities from, or limit the number of Registrable
Securities to be included in, the registration and underwriting.
