ITEM 1. BUSINESS

      Except for the historical information contained herein, the discussion in
this Annual Report on Form 10-K may contain 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
document should be read as applicable to all related forward-looking statements
wherever they appear in this document. The Company's actual results could differ
materially from those discussed herein. Factors that could cause or contribute
to such differences include those discussed below in "Risk Factors," as well as
those discussed elsewhere herein.


                                   THE COMPANY

      InSite Vision Incorporated ("InSite," "InSite Vision" or the "Company") is
an ophthalmic product development company focused on genetic research for
diagnosis and prognosis of glaucoma and the development of treatment products
for ophthalmic diseases using its proprietary DuraSite(R) technology.

      Glaucoma Genetics. The Company's glaucoma genetics program, which is being
carried out in collaboration with academic researchers, is focused on
discovering genes that are associated with glaucoma, and the mutations on these
genes that cause the disease. This genetic information then may be applied to
develop new glaucoma diagnostic, prognostic and management tools. To date, the
Company's academic collaborators have identified genes associated with primary
open-angle glaucoma (the most prevalent form of the disease in adults), juvenile
glaucoma and primary congenital glaucoma. A diagnostic/prognostic technology,
ISV-900, which is capable of identifying multiple glaucoma genetic markers from
a single sample, has been developed by the Company, and was licensed to
Pharmacia & Upjohn ("P&U") in November 1999. (See "--Collaborative and Licensing
Agreements" for additional information on this transaction.) The Company's
academic collaborators for its glaucoma genetics program are at the University
of California, San Francisco ("UCSF"), the University of Connecticut Health
Center ("UCHC"), INSERM, the French equivalent of US National Institutes of
Health and other institutions in North America and Europe.

      DuraSite-Based Product and Candidates. The DuraSite delivery system is a
patented eyedrop formulation comprising a cross-linked carboxyl-containing
polymer which incorporates the drug to be delivered to the eye. The formulation
is instilled in the cul-de-sac of the eye as a small volume eyedrop and remains
in the eye for up to several hours during which time the active drug ingredient
is gradually released. This increased residence time is designed to permit lower
concentrations of a drug to be administered over a longer period of time,
thereby minimizing the inconvenience of frequent dosing and reducing potential
related adverse side effects. Eyedrops delivered in the DuraSite system contrast
to conventional eyedrops which typically only last a few minutes in the eye,
thus requiring delivery of a highly concentrated burst of drug and frequent
administration to sustain therapeutic levels. DuraSite can be customized to
deliver a variety of compounds with a broad range of molecular weights and other
properties.

      Recently, the Company received an additional patent allowance extending
the viscosity and pH ranges of the DuraSite system. This will allow a broader
range of compounds to be delivered by the system and extends the patent coverage
to 2016.

      The first product utilizing the DuraSite technology, AquaSite(R) dry eye
treatment, was launched as an over-the-counter ("OTC") medication in 1992 by
CIBA Vision Ophthalmics ("CIBA Vision"), to which the Company has licensed
certain co-exclusive rights. In 1999, the Company licensed AquaSite to Global
Damon Pharm ("Global Damon") for sale in Korea and SSP Co., Ltd. ("SSP") for
sale in Japan. (See "--Collaborative and Licensing Agreements" for additional
information on the agreements.) In connection with its DuraSite development
efforts, the Company has established collaborations with P&U and British
Biotechnology Pharmaceuticals, Inc. ("British Biotech"), among others, and has
licensed



                                       3
<PAGE>   4

marketing rights to certain DuraSite-based product candidates to P&U, CIBA
Vision and Bausch & Lomb Incorporated ("B&L").

      In January 1999, the Company entered into a license agreement and stock
purchase agreement with P&U for the exclusive worldwide rights to ISV-205 for
glaucoma. (See "--Collaborative and Licensing Agreements" for additional
information on the agreements.) During 1999, the Company successfully completed
Phase II trials of ISV-205 and has transitioned the lead on the further
development of the program to P&U.

      Business Strategy. The Company's business strategy is to license promising
product candidates and technologies from academic institutions and other
companies, to conduct preclinical and limited clinical testing, if necessary,
and to partner with pharmaceutical companies to complete clinical development
and regulatory filings as needed and to market its products. The Company also
has internally developed DuraSite-based product candidates using either
non-proprietary drugs or compounds developed by others for non-ophthalmic
indications. As with in-licensed product candidates, the Company either has or
plans to partner with pharmaceutical companies to complete clinical development
and commercialization of its own product candidates.

OPHTHALMIC PHARMACEUTICAL MARKET

      In 1999, the market for ophthalmic prescription pharmaceuticals in the
U.S. was approximately $1.5 billion. The principal categories of ophthalmic
drugs are glaucoma treatments ($568 million), antibiotics ($254 million),
anti-allergic ($218 million), and anti-viral ($213 million) products. However
many eye conditions, including those that involve damage to the retina, are
untreated at present.

      For example, age-related macular degeneration, which affects 10 million or
more people in the U.S., is the leading cause of severe blindness in Americans
aged 60 and above. Laser treatment is the only known therapy, but is only
effective in about 15% of affected patients. Even with treatment, the disease
usually progresses and eventually leads to vision loss.

      Also, approximately 10 to 14 million Americans are diabetic and many of
them will develop diabetic retinopathy later in their life. Laser therapy, which
is the only approved treatment, is effective only in a certain segment of the
diabetic population, and has potential side effects such as loss of peripheral
vision, retinal detachment, and loss of vision.

      Glaucoma is the leading cause of preventable blindness in the U.S.,
affecting two to three million people. It is estimated that 67 million people
worldwide will have glaucoma by the year 2000. The prevalence of the disease in
first-degree relatives of affected patients has been documented to be as high as
seven to ten times that of the general population. Glaucoma also may occur as a
complication of conditions such as diabetes, or as a result of extended steroid
use.

      The prevalence of eye disease is ten times greater in persons over the age
of 65 than under age 65, and the U.S. Census Bureau projects that the U.S.
population over age 65 will increase from 34 million in 1997 to approximately 69
million by the year 2030. This aging of the population in the U.S. and other
developed countries is a significant factor that the Company believes will
contribute to increased demand for new ophthalmic products.

      In addition to changing demographics, the Company believes that recent
improvements in medical technology, such as increasingly sophisticated
diagnostic techniques, will allow identification of ocular diseases at an
earlier stage, enabling more effective treatments and expanding the range of
treatment regimens available to the ophthalmologist. Further, the Company
believes that the emergence of new laser-based procedures to correct certain
vision problems has begun to increase the need for comfortable, extended-release
drug therapy during the post-surgical ocular healing process.

GLAUCOMA GENETICS

      Glaucoma is the leading cause of preventable blindness in the U.S.,
affecting an estimated two to three million people. Glaucoma-related
pharmaceutical sales were approximately $568 million in the U.S. in 1999. The
most prevalent form of glaucoma in adults is primary open-angle glaucoma. Other
forms of the disease include primary congenital glaucoma, a leading cause of
blindness in infants, and juvenile glaucoma that effects children and young
adults.

      Often called the "sneak thief of sight" because of its lack of symptoms,
glaucoma is believed to result when the flow of fluid through the eye is
impaired. This may lead to elevated intraocular pressure ("IOP"), which
increases pressure on the optic nerve and can cause irreversible vision loss if
left untreated. One form of glaucoma, normal or low tension glaucoma, is
associated with individuals who have normal eye pressure. It is estimated that
one-third of the U.S. glaucoma patients and three-quarters of the glaucoma
patients in Japan have this form of the disease. These patients cannot be
identified with standard glaucoma screening tests that only measure a patient's
eye pressure and usually incur visual field loss before they are diagnosed.

      ISV-900. There is accumulating evidence that genetic predisposition is a
major factor in the development of several forms of glaucoma. (Data has
indicated the prevalence of primary open-angle glaucoma ("POAG") in first-degree
relatives of affected patients to be as high as 7 to 10 times that of the
general population.) InSite Vision has formed research collaborations with
scientists at institutions located in North America, Europe and Japan both to
identify the genes associated with different forms of glaucoma and to build a
database of information on how these genes affect the progression of the disease
in different populations.

      The Company's researchers have identified several genes related to POAG
including TIGR, GLC1B, GLC1D, GLC1E, OCLM and a novel TIGR modifier gene.
Additionally, the CYP1B1 gene has been identified which is related to primary
congenital glaucoma ("PCG"). The Company has obtained exclusive worldwide
licenses for the rights to commercialize research related to the TIGR gene and
associated mutations from the Regents of the University of California ("UC
Regents"), the CYP1B1 gene and associated mutations from UCHC, the OCLM gene
from Dr. Toshihiko Matsuo of Okayama University and a novel TIGR modifier gene
from INSERM. The Company also holds an option to an exclusive worldwide license
for other glaucoma genes.

      InSite Vision currently holds patents issued on the TIGR cDNA, the TIGR
antibody, methods for the diagnosis of glaucoma using the TIGR technology and
methods for the diagnosis of glaucoma using the CYP1B1 technology. Additional
patents related to ISV-900 are currently pending.

      Current glaucoma tests are often unable to detect the disease before
substantial damage to the optic nerve has occurred. Gene-based tests may make it
possible to identify patients at risk and initiate treatment before permanent
optic nerve damage and vision loss occurs. The Company's ISV-900 program is
intended to discover the appropriate genetic markers for certain forms of
glaucoma and to incorporate those markers into prognostic, diagnostic and
management tools. The first version of these tests has been developed by the
Company and, in November 1999, was licensed to P&U. A commercialization plan is
being developed. The Company anticipates that as further research identifies
additional mutations to these genes, and new genes are located, the marketed
test will be modified to incorporate these findings.

GLAUCOMA CANDIDATES

      ISV-205. InSite Vision's ISV-205 product candidate contains the drug
diclofenac formulated in the DuraSite sustained-release delivery vehicle.
Diclofenac is a non-steroidal anti-inflammatory drug ("NSAID") currently used to
treat ocular inflammation. NSAIDs can block steroid-induced IOP elevation by
inhibiting the production of the TIGR protein that appears to affect the fluid
balance in the eye. The ISV-205 product candidate contains concentrations of
diclofenac which have been shown in cell culture systems to inhibit the
production of the TIGR protein.

      A Phase II clinical study was successfully completed in 1999 to evaluate
the efficacy of two concentrations of diclofenac. Analysis of the data from this
study showed that ISV-205 was safe and effective in reducing, by 75%, the number
of subjects with clinically significant IOP elevation following steroid use. A
second Phase II study is being conducted by P&U on a larger patient population.
Other potential indications may include glaucoma prevention, analgesia and
anti-inflammatory indications. Co-exclusive rights, in the U.S., to develop,
manufacture, use and sell ISV-205 to treat inflammation or analgesia, were
licensed to CIBA Vision in May 1996.

      In January 1999, the Company entered into an exclusive worldwide
royalty-bearing license agreement with P&U for ISV-205 for glaucoma. The license
provides for research and development payments to be made to the Company by P&U
and for P&U to assume responsibility for the on-going development of the product
since the completion of the Phase II study conducted by the Company. The Company
will continue to provide P&U with technical assistance on the product. P&U also
made equity investments in the Company and may make additional future equity
investments if certain project milestones are achieved. See "--Collaborative and
Licensing Agreements" for additional information on the agreement.

OTHER TOPICAL PRODUCT CANDIDATES AND PRODUCT

      ISV-401 is a formulation of an antibiotic that has not previously been
used in ophthalmology. The antibiotic, which is effective both for gram-negative
and gram-positive bacteria, may also provide reduced dosing frequency. Current
ophthalmic antibiotics must be dosed every two hours during the first day and
four times a day for the remainder of the treatment period, which may be up to
fourteen days. This may result in patient compliance issues that could be
minimized with an improved product. Also, a broad-spectrum antibiotic could be
used by physicians to treat a variety of ophthalmic diseases instead of
targeting each disease specifically.

      ISV-615 is a DuraSite-based ophthalmic formulation of batimastat that the
Company is evaluating for its potential in preventing neovascularization in the
retina related to diabetic retinopathy and macular degeneration. The Company
obtains batimastat, the active ingredient of ISV-615, through a 1992 agreement
with British Biotech, which in December 1996 advised the Company that it had
discontinued development and manufacturing of batimastat. The Company and
British Biotech are in negotiations on a new licensing agreement related to
batimastat that provides for continued supply of the drug. See "Risk Factors -
Dependence on Third Parties."

      AquaSite. The first product utilizing InSite's DuraSite technology was
introduced to the OTC market in the U.S. in October 1992 by CIBA Vision. The
Company receives a royalty on sales of AquaSite by CIBA Vision. The product
contains the DuraSite formulation and demulcents for the symptomatic treatment
of dry eye. In March 1999, the Company licensed the product to Global Damon
Pharm, a Korean company. The license is royalty-bearing and is exclusive in the
Republic of Korea for up to a 10 year period. In August 1999, the Company
licensed the product to SSP for sales and distribution in Japan.

RETINAL DEVICE

      Ophthalmic conditions that involve retinal damage include macular
degeneration, which affects 10 million or more people in the U.S., and diabetic
retinopathy, a common side effect of diabetes. Approximately ten to fourteen
million people in the U.S. are diabetics. Both macular degeneration and diabetic
retinopathy can lead to irreversible vision loss and blindness. Current
treatment of retinal diseases generally involves surgery and laser treatments
that can lead to loss of vision, retinal detachment and infection. There is no
effective drug therapy for these conditions.

      Retinal Delivery Device. Another technology platform is comprised of a
device, ISV-014, for the



                                       7
<PAGE>   8
controlled, non-surgical delivery of ophthalmic drugs to the retina and
surrounding tissues. In 1999, the Company continued to enhance the device and
performed invivo experiments delivering products with a variety of molecular
sizes to retinal tissues.  The combination of this device technology with
polymer-based drug platforms may permit long term delivery of therapeutic
agents to treat several retinal diseases, most of which cannot be effectively
treated at the present time.

      ISV-014 is a device for the controlled, non-surgical delivery of
ophthalmic drugs to the back of the globe. The device consists of a handle with
a distal platform that is placed against the surface of the eye. A small needle
connected to a drug reservoir is extended from the platform into the tissues of
the eye. Once in place, a metering mechanism controls the amount and rate that
the drug is injected into the tissue. This produces a highly localized depot of
drug inside the ocular tissues. By controlling both the distance and direction
that the needle protrudes, the device greatly reduces the chance that the needle
will penetrate through the sclera of the eye into the underlying tissues, which
are easily damaged. The Company has filed for two patents related to the device
and its use and specific claims to the device have been allowed. The Company is
currently investigating licensing this technology to a third party.

COLLABORATIVE AND LICENSING AGREEMENTS

      As a key element of its business strategy, the Company has entered into,
and will continue to pursue additional research collaborations, licensing
agreements and corporate collaborations. However, there can be no assurance that
the Company will be able to negotiate acceptable collaborative or licensing
agreements, or that its existing collaborations will be successful or will be
renewed when they expire.

      Pharmacia & Upjohn. On November 11, 1999, the Company entered into a
license agreement, stock purchase agreement and credit agreement pursuant to
which InSite granted P&U an exclusive worldwide royalty-bearing license to its
ISV-900 technology for diagnostic, prognostic and therapeutic applications in
the area of glaucoma. The license calls for (i) P&U to pay the Company a
licensing fee, (ii) P&U to make research and development payments to the Company
over three years starting in 2000, (iii) P&U to pay the Company royalties on
product sales should any products be successfully commercialized from this
technology, and (iv) payments by P&U to the Company if certain milestones are
achieved.

      In addition, P&U invested $2,000,000 in the Company's common stock. The
stock purchase agreement also provides for a standstill period of thirty (30)
months during which P&U and its subsidiaries will not purchase additional shares
of the Company, other than those provided for under any existing agreements
between the companies, without the prior written consent of the Company. This
standstill period will terminate earlier if certain actions are taken by other
parties to acquire more than a 9.99% interest in the stock of the Company or if
any other party announces their intention to assume control of the Company,
whether by tender offer, merger, proxy contest or otherwise. Additionally, the
transaction provides for a revolving line of credit to be made available to the
Company beginning November 11, 2001 for a period of three (3) years.

      On January 28, 1999, the Company entered into a license agreement and
stock purchase



                                       8
<PAGE>   9
agreement pursuant to which InSite granted P&U an exclusive worldwide license to
ISV-205 for the treatment of glaucoma. The license calls for (i) P&U to assume
responsibility for the development of the product upon completion by InSite of,
among other activities, Phase II studies conducted by the Company, (ii) P&U to
reimburse InSite for research and development expenses and to make payments to
InSite for on-going technical support, and (iii) the payment by P&U to InSite of
royalties on product sales should ISV-205 be successfully commercialized. InSite
will continue to bear responsibility for the prosecution and maintenance of the
patents subject to the license, among other things. The transaction also called
for an equity investment from P&U, which was made in February 1999, with the
potential for future equity investments at an average of prevailing market
prices if the Company achieves certain milestones.

      CIBA Vision Ophthalmics (CIBA Vision). The Company has entered into
license agreements with CIBA Vision (the "CIBA Vision Agreements"), pursuant to
which the Company granted CIBA Vision a co-exclusive license to manufacture,
have manufactured, use and sell fluorometholone and tear replenishment products
utilizing the DuraSite technology in the U.S. and Canada, ToPreSite, a product
candidate for ocular inflammation/infection, and ISV-205 for non-glaucoma
indications.

      Bausch and Lomb. In July 1996, the Company entered into a license
agreement ("the B&L Agreement") with B&L whereby the Company granted B&L an
exclusive worldwide royalty bearing license to make, use and sell PilaSite and
ISV-208. B&L paid the Company an up-front license fee of $500,000 and is
obligated to pay royalties on net sales of the licensed products. In addition,
B&L made a $2.0 million investment in the Company, is sharing the cost of
developing ISV-208 and agreed to manufacture other products on behalf of the
Company.

      In July 1999, the Company and B&L entered into a termination, release and
purchase agreement whereby the PilaSite license agreement and the manufacturing
agreement were terminated and the Company's equipment located at B&L's facility
was purchased by B&L. The ISV-208 license and development collaboration remains
in effect.

      British Biotech. In November 1992, the Company entered into a
collaboration agreement with British Biotech (the "ISV-120 Agreement"), pursuant
to which British Biotech had granted the Company the right to conduct, at
InSite's own expense, preclinical and clinical trials on British Biotech's
batimastat compound and the exclusive option to initiate negotiations with
British Biotech to pursue further development of ISV-120. In December 1996,
British Biotech advised the Company that it had discontinued its development and
manufacturing of batimastat. The term of the ISV-120 Agreement has expired but
British Biotech is continuing to supply batimastat to the Company while extended
access to the compound for use in its ISV-615 product candidate is being
negotiated.

      INSTITUTE NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE (INSERM). In
December 1999, the Company entered into an exclusive worldwide license agreement
with INSERM for the diagnostic, prognostic and therapeutic uses of a gene for
chronic open angle glaucoma. The Company has paid a licensing fee and will make
royalty payments on future product sales, if any.

      UC Regents. In March 1993, the Company entered into an exclusive license
agreement with the UC Regents for the development of ISV-205 and, in August
1994, the parties entered into another exclusive license agreement for the use
of a nucleic acid sequence that codes for a protein associated with glaucoma.
Under both agreements, the Company paid initial licensing fees and will make
royalty payments to the UC Regents on future product sales, if any.

      University of Connecticut Health Center. In August 1997, the Company
exercised its option to obtain an exclusive worldwide license from UCHC for
diagnostic uses of the newly discovered gene for primary congenital glaucoma.
The Company also has an option for a worldwide exclusive license to



                                       9
<PAGE>   10

commercialize technologies related to certain research UCHC is conducting in the
area of adult-onset glaucoma. Under the agreements, the Company will pay a
licensing fee and will make royalty payments on future product sales, if any.

      Columbia Laboratories, Inc. In February 1992, InSite entered into a
cross-license agreement (the "Columbia Agreement") with Columbia Laboratories,
Inc. ("Columbia"), pursuant to which Columbia granted InSite a perpetual,
exclusive, irrevocable, royalty-free license to a polymer technology upon which
DuraSite is based. This license permits InSite to make, use and sell products
using such polymer technology for non-veterinary ophthalmic indications in the
over-the-counter and prescription markets in North America and East Asia (the
"Columbia Territory"), and in the prescription market in countries outside the
Columbia Territory. In exchange, InSite granted Columbia a perpetual, exclusive,
irrevocable, royalty-free license, with the right to sublicense and use certain
DuraSite technology in the over-the-counter market outside the Columbia
Territory. In addition, InSite also granted Columbia a perpetual, exclusive,
irrevocable, worldwide license to certain DuraSite technology in the veterinary
field. Under certain circumstances, certain of the licenses in the Columbia
Agreement become non-exclusive. Subject to certain rights of early termination,
the Columbia Agreement continues in effect until the later of January 2002 or
expiration of all patents covered by the DuraSite technology to which Columbia
has certain rights.

      Global Damon Pharm and Kukje Pharma Ind. Co., Ltd. In March 1999, the
Company entered into a royalty-bearing license agreement with Global Damon, a
Korean company, to be the exclusive distributor of AquaSite in the Republic of
Korea. Concurrently, the Company entered into a manufacturing agreement with
Kukje Pharma Ind. Co., Ltd ("Kukje"), a Korean company, to produce the AquaSite
to be sold by Global Damon.

      SSP Co., Ltd. In August 1999, the Company entered into an exclusive
license agreement with SSP to be the exclusive manufacturer and distributor of
AquaSite in Japan. The Company will be the sole supplier to SSP for some of the
key ingredients necessary for the manufacture of AquaSite.

      Other. As part of InSite's basic strategy, InSite continually discusses
entering into agreements with other companies, universities and research
institutions concerning the licensing of additional therapeutic agents and drug
delivery technologies to complement and expand InSite's family of proprietary
ophthalmic products. InSite intends to continue exploring licensing and
collaborative opportunities.

PATENTS AND PROPRIETARY RIGHTS

      Patents and other proprietary rights are important to the Company's
business. The Company's policy is to file patent applications seeking to protect
technology, inventions and improvements to its inventions that are considered
important to the development of its business. Additionally, the Company's policy
is to assist the UC Regents, UCHC and INSERM in filing patent applications
seeking to protect inventions which are the subject of the Company's agreements
with those institutions. The Company also relies upon trade secrets, know-how,
continuing technological innovations and licensing opportunities to develop and
maintain its competitive position. InSite's DuraSite drug delivery products are
made under patents and applications, including four U.S. patents, owned by
Columbia and exclusively licensed to InSite in the field of human ophthalmic
applications. See "--Collaborative and Licensing Agreements." In addition, the
Company has filed a number of patent applications in the U.S. relating to the
Company's DuraSite technology, as well as foreign versions of certain of these
applications in many countries. Of these applications, seven U.S. patents have
been issued. In addition, the Company has obtained two U.S. patents on its unit
dose dispenser. The Company has received six additional U.S. patents directed
toward certain uses of lazaroids in ophthalmic applications. Of the patent
applications licensed from the UC Regents, eight patents have issued. Two
patents have been issued of the patent applications licensed from UCHC covering
the diagnosis of primary congenital glaucoma. Two patent applications have been
filed by the Company on its retinal delivery device and its use for delivery of
drugs to the retina. Several other patent applications by the Company and by the
UC Regents, UCHC and INSERM relating to the foregoing and other aspects of the
Company's business and potential business are also pending.



                                       10
<PAGE>   11

      The patent positions of pharmaceutical companies, including InSite, are
uncertain and involve complex legal and factual questions. In addition, the
coverage claimed in a patent application can be significantly reduced before a
patent is issued. Consequently, the Company does not know whether any of its
pending patent applications will result in the issuance of patents or if any of
its patents will provide significant proprietary protection. Since patent
applications are maintained in secrecy until patents issue in the U.S., or such
patents are published by foreign regulatory authorities, the Company cannot be
certain that it or any licensor was the first to file patent applications for
such inventions. Moreover, the Company might have to participate in interference
proceedings declared by the U.S. Patent and Trademark Office to determine
priority of invention, which could result in substantial cost to the Company,
even if the eventual outcome were favorable. There can be no assurance that the
Company's patents will be held valid or enforceable by a court or that a
competitor's technology or product would be found to infringe such patents.

      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.

      In addition to patent protection, the Company also relies upon trade
secret protection for its confidential and proprietary information. 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.

ACCESS TO PROPRIETARY COMPOUNDS

      The Company believes its drug delivery technology may expand the
ophthalmic pharmaceutical market by permitting the novel use of drugs for
ophthalmic indications that are currently used or being developed for
non-ophthalmic indications. However, the Company may be required to obtain
licenses from third parties that have rights to these compounds in order to
conduct certain research, to develop or to market products that contain such
compounds. There can be no assurance that such licenses will be available on
commercially reasonable terms, if at all. See "Business - Collaborative and
Licensing Agreements."

RESEARCH AND DEVELOPMENT

      The Company's research and development staff at December 31, 1999 numbered
24 people, of whom 8 have Ph.D's. Research and development expenses sponsored by
the Company during 1999 were $1.4 million, which is net of $4.2 million funded
by P&U as part of the ISV-205 license. During 1998 and 1997, research and
development expenses were $6.2 million and $7.2 million, which is net of
$361,000 and $534,000, respectively, funded by (i) P&U and (ii) B&L, as part of
the 1996 ISV-208 joint development agreement. See "Collaborative and Licensing
Agreements" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

MANUFACTURING

      The Company has no experience or facilities for the manufacture of
products for commercial processes. Moreover, the Company currently has no
intention of developing such experience or



                                       11
<PAGE>   12

implementing such facilities. The Company has a pilot facility, licensed by the
State of California, to produce potential products for Phase I and some of its
Phase II clinical trials. However, as stated above, the Company has no
large-scale manufacturing capacity and relies on third parties, such as P&U, for
supplies and materials necessary for all of its Phase III clinical trials. If
the Company should encounter delays or difficulties in establishing and
maintaining its relationship with 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. See "Risk Factors - No Commercial Manufacturing Experience."

MARKETING AND SALES

      In connection with its November 1995 restructuring, the Company elected
not to proceed with plans to establish its own sales and marketing organization.
Instead, the Company has entered into arrangements and plans to enter into
arrangements with one or more additional pharmaceutical companies to market its
products. There can be no assurance that the Company will be able to conclude or
maintain such arrangements on acceptable terms, if at all.

      Bausch and Lomb. In July 1996, the Company entered into an exclusive
worldwide royalty-bearing license agreement whereby B&L has agreed to market
and sell ISV-208. Under the terms of the agreement, the Company is entitled to
royalties based on net sales of the products, if any. See "Risk Factors -
Marketing and Sales."

      CIBA Vision. In 1991, the Company entered into a co-exclusive rights
agreement to market the AquaSite product in the U.S. and Canada. Additionally,
in May 1996, the Company granted CIBA Vision a co-exclusive U.S. license for
ISV-205 for non-glaucoma indications, and co-exclusive marketing rights within
the U.S. to sell and use ToPreSite. InSite Vision's trademark is being used,
under license, by CIBA Vision for AquaSite dry eye treatment and the Company's
patents are identified on the AquaSite packaging. The Company received a
one-time licensing fee and is entitled to royalties based on net sales of the
products, if any.

      Global Damon Pharm ("Global Damon") and Kukje Pharma Ind. Co., Ltd.
("Kukje"). In March 1999, the Company entered into a royalty-bearing licensing
agreement with Global Damon, a Korean company, to be the exclusive distributor
of AquaSite in the Republic of Korea. Concurrently, the Company entered into a
manufacturing agreement with Kukje, a Korean company, to produce the AquaSite to
be sold by Global Damon.

      Pharmacia & Upjohn. In November 1999, the Company entered into an
exclusive worldwide royalty-bearing license agreement whereby P&U has agreed to
market and sell ISV-900 for prognosis, diagnosis and treatment of glaucoma.
Under the terms of the agreement, the Company is entitled to royalties based on
net sales of the products, if any.

      In January 1999, the Company entered into an exclusive worldwide
royalty-bearing license agreement whereby P&U has agreed to market and sell
ISV-205 for glaucoma related indications. Under the terms of the agreement, the
Company is entitled to royalties based on net sales of the product, if any.

      SSP Co., Ltd. In August 1999, the Company entered into an exclusive
licensing agreement with SSP to be the exclusive manufacturer and distributor of
AquaSite in Japan. The Company will be the sole supplier to SSP for certain key
ingredients necessary for the manufacture of AquaSite.

COMPETITION



                                       12
<PAGE>   13

      There are many competitors of the Company in the U.S. and abroad. These
companies include ophthalmic-oriented companies that market a broad portfolio of
products, as well as large integrated pharmaceutical companies that market a
limited number of ophthalmic pharmaceuticals in addition to many other
pharmaceuticals. Many of these companies have substantially greater financial,
technical, marketing and human resources than those of the Company and may
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. These competitors may also succeed in obtaining cost advantages,
patent protection or other intellectual property rights that would block the
Company's ability to develop its potential products, or in obtaining regulatory
approval for the commercialization of their products more rapidly or effectively
than the Company. The ophthalmic prescription pharmaceutical market in the U.S.
is dominated by six companies: Allergan Pharmaceuticals, a division of Allergan,
Inc.; Alcon Laboratories, Inc., a division of Nestle Company; Bausch and Lomb;
CIBA Vision, a division of Novartis Ltd.; Merck, Sharp & Dohme, a division of
Merck & Co., Inc.; and Pharmacia & Upjohn, Inc.

      The Company believes that there will be increasing competition from new
products entering the market that are covered by exclusive marketing rights and,
to a lesser degree, from pharmaceuticals that become generic. The Company is
aware of certain products manufactured or under development by competitors that
are used for the treatment of certain ophthalmic indications which the Company
has targeted for product development. The Company's competitive position will
depend on its ability to develop enhanced or innovative pharmaceuticals,
maintain a proprietary position in its technology and products, obtain required
governmental approvals on a timely basis, attract and retain key personnel and
develop effective products that can be manufactured on a cost-effective basis
and marketed successfully.

      Over the longer term, the Company's (and its partners') ability to
successfully market the current products, expand its usage and bring new
products to the marketplace, will depend on many factors, including the
effectiveness and safety of the products, and competing products, approved by
the FDA and foreign regulatory agencies, the degree of patent protection
afforded to particular products, and the effect of the advent of managed care as
an important purchaser of pharmaceutical products. See "Risk Factors -
Competition."

GOVERNMENT REGULATION

      The manufacturing and marketing of the Company's products and its research
and development activities are subject to regulation by numerous governmental
authorities in the U.S. and other countries. In the U.S., drugs are subject to
rigorous FDA regulation. The Federal Food, Drug and Cosmetic Act and regulations
promulgated thereunder govern the testing, manufacture, labeling, storage,
record keeping, approval, advertising and promotion in the U.S. of the Company's
products. In addition to FDA regulations, the Company is also subject to other
federal and state regulations such as the Occupational Safety and Health Act and
the Environmental Protection Act. Product development and approval within this
regulatory framework take a number of years and involve the expenditure of
substantial resources.

      While the FDA currently does not regulate genetic tests, it has stated
that it has the right to do so, and there can be no assurance that the FDA will
not seek to regulate such tests in the future. If the FDA should require that
genetic tests receive FDA approval prior to their use, there can be no assurance
such approval would be received on a timely basis, if at all. The failure to
receive such approval could require the Company to develop alternative testing
methods, which could result in the delay of such tests reaching the market, if
at all. Such a delay could have a materially adverse effect on the Company.

      The steps required before a pharmaceutical agent may be marketed in the
U.S. include (i) preclinical laboratory and animal tests, (ii) the submission to
the FDA of an IND, (iii) adequate and well-controlled human clinical trials to
establish the safety and efficacy of the drug, (iv) the submission of an NDA or
Product License Application ("PLA") to the FDA and (v) the FDA approval of the
NDA or PLA, prior to any commercial sale or shipment of the drug. In addition to
obtaining FDA approval for each



                                       13
<PAGE>   14

product, each domestic drug manufacturing establishment must be registered with,
and approved by, the FDA. Drug product manufacturing establishments located in
California also must be licensed by the State of California in compliance with
separate regulatory requirements.

      Preclinical tests include laboratory evaluation of product chemistry and
animal studies to assess the potential safety and efficacy of the product and
its formulation. The results of the preclinical tests are submitted to the FDA
as part of an IND and, unless the FDA objects, the IND will become effective 30
days following its receipt by the FDA.

      Clinical trials involve the administration of the drug to healthy
volunteers or to patients under the supervision of a qualified principal
investigator. Clinical trials are conducted in accordance with protocols that
detail the objectives of the study, the parameters to be used to monitor safety,
and the efficacy criteria to be evaluated. Each protocol is submitted to the FDA
as part of the IND. Each clinical study is conducted under the auspices of an
independent Institutional Review Board which considers, among other things,
ethical factors and the rights, welfare and safety of human subjects.

      Clinical trials are typically conducted in three sequential phases, but
the phases may overlap. In Phase I, the initial introduction of the drug into
human subjects, the drug is tested for safety (adverse effects), dosage
tolerance, metabolism, distribution, excretion and clinical pharmacology. Phase
II involves studies in a limited patient population to (i) determine the
efficacy of the drug for specific targeted indications, (ii) determine dosage
tolerance and optimal dosage and (iii) identify possible adverse effects and
safety risks. When a compound is found to be effective and to have an acceptable
safety profile in Phase II evaluations, Phase III trials are undertaken to
further evaluate clinical efficacy and to further test for safety within an
expanded patient population at multiple clinical study sites. The FDA reviews
both the clinical plans and the results of the trials and may discontinue the
trials at any time if there are significant safety issues.

      The results of the preclinical studies and clinical studies are submitted
to the FDA in the form of an NDA or PLA for marketing approval. The testing and
approval process is likely to require substantial time and effort and there can
be no assurance that any approval will be granted on a timely basis, if at all.
Additional animal studies or clinical trials may be requested during the FDA
review period and may delay marketing approval. After FDA approval for the
initial indications, further clinical trials are necessary to gain approval for
the use of the product for additional indications. The FDA may also require
post-marketing testing to monitor for adverse effects, which can involve
significant expense.

      Among the conditions for manufacture of clinical drug supplies and for NDA
or PLA approval is the requirement that the prospective manufacturer's quality
control and manufacturing procedures conform to GMP. Prior to approval,
manufacturing facilities are subject to FDA and/or other regulatory agency
inspection to ensure compliance with GMP. Manufacturing facilities are subject
to periodic regulatory inspection to ensure ongoing compliance.

      For marketing outside the U.S., the Company also is subject to foreign
regulatory requirements governing human clinical trials and marketing approval
for drugs. The requirements governing the conduct of clinical trials, product
licensing, pricing and reimbursement vary widely from country to country.

SCIENTIFIC AND BUSINESS ADVISORS

      The Company has access to a number of academic and industry advisors with
expertise in clinical ophthalmology and pharmaceutical development, marketing
and sales. The Company's advisors meet with management and key scientific
employees of the Company on an ad hoc basis to provide advice in their
respective areas of expertise and further assist the Company by periodically
reviewing with management the Company's preclinical, clinical and marketing
activities. The Company plans to make arrangements with other individuals to
join as advisors as appropriate. Although the Company expects to receive
guidance from the advisors, all of the advisors are employed on a full-time
basis by other entities, or are



                                       14
<PAGE>   15

primarily engaged in business activities outside the Company, and may have other
commitments to, or consulting or advisory contracts with, other entities that
may conflict or compete with their obligations to the Company.

      The Company's advisors are as follows:

EMPLOYEES

      As of December 31, 1999, the Company employed 34 persons, including 30
full time employees. None of the Company's employees are covered by a collective
bargaining agreement. The Company considers its employee relations to be good.
The Company also utilizes independent consultants to provide services to the
Company in certain areas of its scientific and business operations.


                                  RISK FACTORS

IT IS DIFFICULT TO EVALUATE OUR BUSINESS BECAUSE WE ARE IN AN EARLY STAGE OF
DEVELOPMENT AND OUR TECHNOLOGY IS UNTESTED

      We are in an early stage of developing our business. We are currently only
receiving a small amount of royalties from the sale of one of our products, an
over-the-counter, or OTC, dry eye treatment. Before regulatory authorities will
grant us marketing approval, we will need to conduct significant additional
research and development and preclinical and clinical testing. All of our
products are subject to risks that are inherent to products based upon new
technologies. These risks include the risks that our products:

- -     will be found to be unsafe or ineffective;

- -     will fail to receive necessary marketing clearance from regulatory
      authorities;

- -     even if safe and effective, will be too difficult to manufacture or
      market;

- -     will be unmarketable due to the proprietary rights of third parties; or



                                       15
<PAGE>   16

- -     will not be able to compete with superior, equivalent or more
      cost-effective products offered by third parties.

Therefore, we cannot guarantee that our research and development activities will
result in any commercially viable products.

WE WILL REQUIRE SIGNIFICANT ADDITIONAL FUNDING FOR OUR CAPITAL REQUIREMENTS

      We will require substantial additional funding to develop and conduct
testing on our potential products. We will also require additional funding to
manufacture and market any products which we do develop. Our future capital
requirements will depend upon many factors, including:

- -     the progress of our research and development programs;

- -     the progress of preclinical and clinical testing;

- -     our ability to establish additional corporate partnerships to develop,
      manufacture and market our potential products;

- -     the time and cost 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 our existing collaborative and licensing relationships; and

- -     the purchase of additional capital equipment.

      In addition, as part of the ISV-900 licensing activities, we received a $5
million up front licensing fee from P&U. The UC Regents have alleged that they
are entitled to receive up to $2.5 million of this payment under the terms of
the August 1994 license agreement between us and the UC Regents. We dispute this
allegation and the parties are currently discussing a resolution to this
conflict. We cannot assure you that we will be able to settle this dispute on
acceptable terms or at all and our failure to prevail in this negotiation could
significantly increase our future capital requirements and could significantly
harm our business and financial condition. In addition, any litigation that
results from this dispute, even if successful, could result in substantial cost
to, and diversion of effort by, us and could harm our business and financial
condition.

      We are currently seeking additional funding through public or private
equity or debt financing, collaborative or other arrangements, and from other
sources. We cannot be certain that we will be able to secure additional funding
from these sources, or that such funding will be on terms acceptable to us. If
we fail to secure additional funding upon acceptable terms, our business will be
harmed.

      If we raise additional funds by issuing equity securities, our
stockholders will suffer substantial dilution. However, if we cannot raise
additional funding, we may be required to delay, scale back or eliminate one or
more of our research, discovery or development programs, or scale back or cease
operations altogether. In addition, the failure to raise additional funding may
force us to enter into agreements with third parties on terms which are
disadvantageous to us, which may, among other things, require us to relinquish
rights to our technologies, products or potential products.

      We believe our cash and cash equivalents are sufficient to finance our
working capital and capital expenditure requirements through December 31, 2000.

WE EXPECT TO CONTINUE TO SUFFER LOSSES

      We have incurred significant operating losses since our inception in 1986.
As of December 31, 1999, our accumulated deficit was approximately $84.8
million. Although we achieved profitability in 1999, we expect to incur net
losses for the foreseeable future or until we are able to achieve significant
royalties from sale of our licensed products.



                                       16
<PAGE>   17

      Our ability to achieve significant revenue or profitability depends upon
our ability, alone or with third parties, to successfully develop our potential
products, conduct clinical trials, obtain required regulatory approvals and
successfully manufacture and market our products. We cannot be certain that we
will ever achieve or be able to maintain significant revenue or profitability.

WE RELY ON THIRD PARTIES TO DEVELOP, MARKET AND SELL OUR PRODUCTS

      We have not established a dedicated sales and marketing organization.
Therefore, if we are to successfully commercialize our product candidates, we
will be required to enter into arrangements with one or more third parties that
will:

- -     provide for Phase III clinical testing;

- -     provide for commercial scale up and manufacture of our potential products;

- -     obtain or assist us in other activities associated with obtaining
      regulatory approvals for our product candidates; and

- -     market and sell our products, if they are approved.

      There can be no assurance that we will be able to enter into such
arrangements on acceptable terms, if at all. If we are not successful in
concluding such arrangements, we may be required to establish our own sales and
marketing organization, although we have no experience in sales, marketing or
distribution. We cannot be certain we would be able to build such a marketing
staff or sales force, or that our sales and marketing efforts will be
cost-effective or successful.

      Our strategy for research, development and commercialization of certain of
our products requires us to enter into various arrangements with corporate and
academic collaborators, licensors, licensees and others. Furthermore, we are
dependent on the diligent efforts and subsequent success of these outside
parties in performing their responsibilities. See "Business - Collaborative and
Licensing Agreements".

      We are dependent upon British Biotechnology Pharmaceuticals, Inc., or
British Biotech, for the supply of batimastat, the active drugs incorporated
into the Company's ISV-615 product candidate. British Biotech has discontinued
clinical testing of batimastat and informed us that it will no longer
manufacture the product. We may have no source of ongoing raw materials for
ISV-615. If this turns out to be true, our business may be harmed.

      We cannot be certain that, even if regulatory approvals are obtained, our
products will be marketed diligently or successfully by our partners, or that we
will be able to conclude arrangements with other companies to support the
commercialization of other products on acceptable terms, if at all.

      In addition, we cannot be certain our collaborators will not take the
position that they are free to compete using our technology without compensating
or entering into agreements with us. Furthermore, we cannot be certain our
collaborators will not pursue alternative technologies or develop alternative
products either on their own or in collaboration with others, including our
competitors, as a means for developing treatments for the diseases or disorders
targeted by these collaborative programs.

      We plan to market and sell products through arrangements with third
parties with expertise in the ophthalmic drug or diagnostic industries. There
can be no assurance that we will be able to enter into such arrangements on
acceptable terms, if at all. If we are not successful in concluding such
arrangements, we may be required to establish our own sales and marketing
organization, although we have no experience in sales, marketing or
distribution. We cannot be certain we would be able to build such a marketing
staff or sales force, or that our sales and marketing efforts will be
cost-effective or successful. To the extent we have entered into or will enter
into co-marketing, co-promotion or other licensing arrangements for the
marketing and sale of our products, any revenues received by us will be
dependent on the efforts of third parties, such as CIBA Vision, P&U and B&L. We
cannot be certain that these partners will diligently or successfully market our
products or that such efforts will be successful.



                                       17
<PAGE>   18

OUR BUSINESS DEPENDS UPON OUR PROPRIETARY RIGHTS, AND THERE IS A RISK OF
INFRINGEMENT

      Our success will depend in large part on our ability to obtain patents,
protect trade secrets, obtain and maintain rights to technology developed by
others, and operate without infringing upon the proprietary rights of others. A
substantial number of patents in the field of ophthalmology and genetics 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 ours. We cannot be certain that our
patent applications will be approved, that we will develop additional
proprietary products that are patentable, that any issued patents will provide
us with adequate protection for our inventions or will not be challenged by
others, or that the patents of others will not impair our ability to
commercialize our products. The patent positions of firms in the pharmaceutical
and genetic industries generally are highly uncertain, involve complex legal and
factual questions, and have 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 and genetic patents. Despite our efforts to
protect our proprietary rights, we cannot be certain others will not
independently develop similar products, duplicate any of our products or design
around any of our patents or that third parties from which we have licensed or
otherwise obtained technology will not attempt to terminate or scale back our
rights.

      A number of pharmaceutical and biotechnology companies and research and
academic institutions have developed technologies, filed patent applications or
received patents on various technologies that may be related to our business.
Some of these technologies, applications or patents may conflict with our
technologies or patent applications. Such conflicts could limit the scope of the
patents, if any, we may be



                                       18
<PAGE>   19

able to obtain or result in the denial of our patent applications. In addition,
if patents that cover our activities have been or are issued to other companies,
there can be no assurance that we will 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 we do not obtain such licenses, we 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 us or to protect trade secrets or
know-how owned or licensed by us. Such litigation could result in substantial
cost to and diversion of effort by the Company, all of which may harm our
business. We have also agreed to indemnify our licensees, including P&U, against
infringement claims by third parties related to our technology, which could
result in additional litigation costs and liability, which could harm our
business. In addition, we cannot be certain our efforts to protect or defend our
proprietary rights will be successful or, even if successful, will not result in
substantial cost to us.

      We also depend upon unpatented trade secrets to maintain our competitive
position. We cannot be certain others will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to our trade secrets, that such trade secrets will not be disclosed
or that we can effectively protect our rights to unpatented trade secrets. To
the extent that we or our consultants or research collaborators use intellectual
property owned by others in their work for us, disputes also may arise as to the
rights in related or resulting know-how and inventions.

ACQUISITIONS MAY PRESENT RISKS TO OUR BUSINESS

      At some point in the future, we may pursue acquisitions of companies,
product lines, technologies or businesses that our management believes are
complementary or otherwise beneficial to our Company. In the event that such an
acquisition does occur, we cannot be certain how such acquisitions will affect
our business. Future acquisitions may result in substantial dilution to our
stockholders, the incurrence of additional debt and amortization expenses
related to goodwill, research and development and other intangible assets, all
of which could harm our business. In addition, acquisitions would involve
several risks for us, including:

      -     assimilating employees, operations, technologies and products from
            the acquired companies with our existing employees, operation,
            technologies and products;

      -     diverting our management's attention from day-to-day operation of
            our business;

      -     entering markets in which we have no or limited direct experience;
            and

      -     potentially losing key employees from the acquired companies.

WE HAVE NO EXPERIENCE IN COMMERCIAL MANUFACTURING AND WE RELY ON A SOLE SOURCE
FOR CERTAIN RAW MATERIALS

      We have no experience manufacturing products for commercial purposes. We
have a pilot facility licensed by the State of California to manufacture certain
of our products for Phase I and Phase II clinical trials. In July 1999, we
terminated our alliance under which B&L agreed to manufacture our products.
Should we encounter delays or difficulties in establishing and maintaining a
relationship with other qualified manufacturers to produce, package and
distribute our finished products, then clinical trials, regulatory filings,
market introduction and subsequent sales of our products will be harmed.

      Contract manufacturers must adhere to Good Manufacturing Practices, or
GMP, regulations which are strictly enforced by the FDA on an ongoing basis
through its facilities inspection program. Contract manufacturing facilities
must pass a pre-approval plant inspection before the FDA will approve an New
Drug Application (NDA). Certain material manufacturing changes that occur after
approval are also subject to FDA review and clearance or approval. We cannot be
certain the FDA or other regulatory agencies will approve the process or the
facilities by which any of our products may be manufactured. Our dependence on
third parties for manufacture of products may harm our ability to develop and
deliver products on a timely and competitive basis. Should we be required to
manufacture products ourselves, we:



                                       19
<PAGE>   20

- -     will be required to expend significant amounts of capital to install a
      manufacturing capability;

- -     will be subject to the regulatory requirements described above;

- -     will be subject to similar risks regarding delays or difficulties
      encountered in manufacturing any such products; and

- -     will require substantial additional capital.

      We cannot be certain we will be able to manufacture any products
successfully or in a cost-effective manner. In addition, certain of the raw
materials we use in formulating our DuraSite drug delivery system are available
from only one source. Any significant interruption in the supply of these raw
materials could delay our clinical trials, product development or product sales
and could harm our business.

OUR PRODUCTS ARE SUBJECT TO GOVERNMENT REGULATIONS AND 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 our activities.
We cannot be certain the FDA or any other regulatory agency will grant approval
for any products we develop 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 that 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 after we have obtained regulatory approval, later discovery of
previously unknown problems with a product may result in restrictions on the
product, including withdrawal of the product from the market. Moreover, the FDA
has recently reduced previous restrictions on the marketing, sale and
prescription of products for indications other than those specifically approved
by the FDA. Accordingly, even if we receive FDA approval of a product for
certain indicated uses, our competitors, including our collaborators, could
market products for such indications even if such products have not been
specifically approved for such indications. Delay in obtaining or failure to
obtain regulatory approvals would harm our business.

      The FDA's policies may change and additional government regulations may be
promulgated which could prevent or delay regulatory approval of our potential
products. Moreover, increased attention to the containment of health care costs
in the U.S. could result in new government regulations that could harm our
business. We cannot predict the likelihood of adverse governmental regulation
that might arise from future legislative or administrative action, either in the
U.S. or abroad. See "Risk Factors -- We face risks from the uncertainties of
pricing and other regulation".

WE COMPETE IN HIGHLY COMPETITIVE MARKETS



                                       20
<PAGE>   21

      Our success depends upon developing and maintaining a competitive position
in the development of products and technologies in our areas of focus. We have
many competitors in the U.S. and abroad, including pharmaceutical, biotechnology
and other companies with varying resources and degrees of concentration in the
ophthalmic market. Our competitors may have existing products or products under
development which may be technically superior to ours 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. Many of our competitors have substantially
greater financial, technical, marketing, manufacturing and human resources. In
addition, they may also succeed in developing technologies and products that are
more effective, safer, less expensive or otherwise more commercially acceptable
than any which we have or will develop. Our competitors may obtain cost
advantages, patent protection or other intellectual property rights that would
block or limit our ability to develop our potential products, or may obtain
regulatory approval for commercialization of their products more effectively or
rapidly than we will. To the extent we decide to manufacture and market our
products by ourselves, we will also compete with respect to manufacturing
efficiency and marketing capabilities, areas in which we have limited or no
experience.

WE ARE DEPENDENT UPON KEY EMPLOYEES

      We are highly dependent on Dr. Chandrasekaran and other principal members
of our 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
our success. Competition for skilled individuals in the biotechnology business
is highly intense, and we cannot be certain we will be able to continue to
attract and retain personnel necessary for the development of our business. The
loss of key personnel or the failure to recruit additional personnel or to
develop needed expertise could harm our business.

OUR INSURANCE COVERAGE MAY NOT ADEQUATELY COVER OUR POTENTIAL PRODUCT LIABILITY
EXPOSURE

      We are exposed to potential product liability risks which are inherent in
the development, testing, manufacturing, marketing and sale of human therapeutic
products. Product liability insurance for the pharmaceutical industry is
generally expensive. We cannot be certain that our present product liability
insurance coverage is adequate. Such existing coverage will not be adequate as
we further develop our products, and we cannot be certain that adequate
insurance coverage against potential claims will be available in sufficient
amounts or at a reasonable cost.

WE FACE RISKS FROM THE UNCERTAINTIES OF PRICING AND OTHER REGULATION

      Our business may be harmed 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 U.S., there have
been, and we expect there will continue to be, a number of federal and state
proposals to implement similar government control. While we cannot predict
whether any such legislative or regulatory proposals or reforms will be adopted,
the announcement of such proposals or reforms could harm our business, including
our ability to raise capital or form collaborations. The adoption of such
proposals or reforms could further harm our business.

      In addition, in the U.S. 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 we succeed in bringing one or more products to the
market, we cannot be certain that reimbursement from third party payers will be
available or will be sufficient to allow us to sell our products on a
competitive or



                                       21
<PAGE>   22

profitable basis.

WE USE HAZARDOUS MATERIALS WHICH MAY POSE ENVIRONMENTAL RISKS

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

OUR OFFICERS AND DIRECTORS WILL BE ABLE TO EXERT SIGNIFICANT CONTROL ON INSITE

      As of December 31, 1999, our management and principal stockholders
together beneficially owned approximately 25% of our outstanding shares of
common stock. As a result, these stockholders, acting together, may be able to
effectively control all matters requiring approval by our stockholders,
including the election of a majority of our directors and the approval of
business combinations.

THE PRICE OF OUR COMMON STOCK IS VOLATILE

      The market prices for securities of biopharmaceutical and biotechnology
companies, including ours, have 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. In addition,
future announcements concerning InSite, our 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 us or others and
general market conditions, may have a significant effect on the market price of
our common stock. We have not paid any cash dividends on our common stock, and
we do not anticipate paying any dividends in the foreseeable future.

WE HAVE ADOPTED CERTAIN ANTI-TAKEOVER PROVISIONS

      Certain provisions of our certificate of incorporation and bylaws may have
the effect of making it more difficult for a third party to acquire, or
discouraging a third party from attempting to acquire, control of InSite. Such
provisions could limit the price that certain investors might be willing to pay
in the future for shares of our common stock. The board of directors has the
authority to issue up to 5,000,000 shares of preferred stock, 7,070 of which
have been designated as Series A Convertible Redeemable Preferred Stock.
Furthermore, the board of directors has the authority to determine the price,
rights, preferences, privileges and restrictions of the remaining unissued
shares of preferred stock without any further vote or action by the
stockholders. The rights of the holders of common stock will be subject to, and
may be adversely affected by, the rights of the holders of any preferred shares
and of preferred stock that may be issued in the future. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire a majority of our
outstanding voting stock. Certain provisions of Delaware law applicable to us
could also delay or make more difficult a merger, tender offer or proxy contest
involving us, including Section 203 of the Delaware General Corporation Law,
which prohibits a Delaware corporation from engaging in any business combination
with any interested stockholder for a period of three years unless certain
conditions are met.

WE HAVE CONVERTIBLE, REDEEMABLE SECURITIES THAT MAY RESULT IN DILUTION FOR
COMMON STOCKHOLDERS

      Sales of a substantial number of shares of common stock issuable upon
conversion of our Series A Convertible Redeemable Preferred Stock could
adversely affect the market value of the common stock,



                                       22
<PAGE>   23

depending upon the timing of such sales, and may effect a substantial dilution
of the book value per share of our common stock.

      As of December 31, 1999, warrants for 70 shares of Series A Convertible
Redeemable Preferred Stock were issued and outstanding. The actual number of
shares of common stock issuable upon exercise and conversion of the warrants for
outstanding Series A Convertible Redeemable Preferred Stock will equal:

            (i)   the aggregate stated value of the Series A Convertible
      Redeemable Preferred Stock then being converted ($1,000 per share) plus a
      premium in the amount of 6% per annum accruing from September 12, 1997
      through the date of conversion, divided by

            (ii)  a conversion price equal to the lower of $2.127 or the product
      of the average of the lowest closing bid prices for our common stock for
      any 5 trading days during the 22 consecutive trading day period
      immediately preceding the date of conversion, subject to adjustment in
      accordance with the terms of the Certificate of Designations, Preferences
      and Rights for the Series A Convertible Redeemable Preferred Stock,
      multiplied by a conversion percentage equal to 82.5%.

      For a complete description of the relative rights, preferences,
privileges, powers and restrictions of the Series A Convertible Redeemable
Preferred Stock, see the Certificate of Designations, Preferences and Rights
attached as Exhibit 4.1 to the Registration Statement on Form S-3 filed with the
Securities and Exchange Commission on September 29, 1997. Depending on market
conditions at the time of conversion, the number of shares of common stock
issuable could increase significantly in the event of a decrease in the trading
price of the common stock. Investors in common stock could therefore experience
a dilution upon conversion of the Series A Convertible Redeemable Preferred
Stock. In addition, in the event that the holder of the warrant for Series A
Convertible Redeemable Preferred Stock is unable to convert any such securities
into common stock, the holder may cause us to redeem in cash any such Series A
Convertible Redeemable Preferred Stock that cannot be so converted. In the event
that we fail to so redeem such shares, the holder of the Series A Convertible
Redeemable Preferred Stock are entitled to additional remedies as set forth in
the Certificate of Designations, Preferences and Rights.

ITEM 7. 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 Item 8 of this Form 10-K.

      Except for the historical information contained herein, the discussion in
this Annual Report on Form 10-K may contain 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
document should be read as being applicable to all related forward-looking
statements wherever they appear in this document. The Company's actual results
could differ materially from those discussed herein. Factors that could cause or
contribute to such differences include those discussed below and under "Risk
Factors" in Item 1 of this Form 10-K, as well as those discussed elsewhere
herein.

OVERVIEW

      InSite Vision is developing genetically-based tools for the diagnosis,
prognosis and management of glaucoma and ophthalmic pharmaceutical products
based on its proprietary DuraSite eyedrop-based drug delivery technology.

      The Company is collaborating with academic researchers to develop new
diagnostic, prognostic and management tools for primary congenital, juvenile and
primary open angle glaucomas. Primary congenital glaucoma is an inherited eye
disorder and is one of the leading causes of blindness and visual impairment
affecting infants. A gene-based diagnostic kit may allow early detection of the
disease before considerable irreversible damage has occurred and may improve the
ability to treat it successfully. Primary open angle glaucoma usually affects
people over the age of forty. Current glaucoma tests are generally unable to
detect the disease before substantial damage to the optic nerve has occurred.
Gene-based tests may make it possible to identify patients at risk and initiate
treatment before permanent optic nerve damage and vision loss occurs.

      The Company has international and national collaborations with academic
institutions for the identification and clinical evaluation of genetic markers
for glaucoma. To date, the Company's academic collaborators at UCSF and UCHC
have identified genes associated with primary open-angle glaucoma (the most
prevalent form of the disease in adults), juvenile glaucoma and primary
congenital glaucoma. A diagnostic/prognostic technology, ISV-900, which is
capable of identifying multiple glaucoma genetic markers from a single sample,
has been developed and, in November 1999, the Company licensed the technology to
P&U. See "--Collaborative and Licensing Agreements" for additional information
on the agreement.

      Another result of the glaucoma genetics research has been the development
of the ISV-205 product candidate. This DuraSite formulation contains a drug that
has been shown in cell and organ culture systems to inhibit the production of a
protein that appears to cause glaucoma. In January 1999, the Company entered
into a transaction that granted P&U an exclusive worldwide license for ISV-205
for the treatment of glaucoma. See "Collaborative and Licensing Agreements" for
additional discussion of the transaction. In June 1999, the Company announced
positive results from its Phase II trial of ISV-205. P&U has assumed the
continued development of the product with the continued technical support of the
Company.

      The DuraSite delivery system is a patented eyedrop formulation comprising
a cross-linked carboxyl-containing polymer which incorporates the drug to be
delivered to the eye. The formulation is instilled in the cul-de-sac of the eye
as a small volume eyedrop. DuraSite can be customized to deliver a wide variety
of potential drug candidates with a broad range of molecular weights and other
properties. The DuraSite formulation remains in the eye for up to several hours
during which time the active drug ingredient is gradually released. DuraSite
extends the residence time of the drug due to a combination of mucoadhesion,
surface tension and viscosity. Eyedrops delivered in the DuraSite system
contrast to conventional eyedrops which typically only last in the eye a few
minutes, thus requiring delivery of a



                                       32
<PAGE>   31

highly concentrated burst of drug and frequent administration to sustain
therapeutic levels. The increased residence time for DuraSite is designed to
permit lower concentrations of a drug to be administered over a longer period of
time, thereby minimizing the inconvenience of frequent dosing and reducing the
potential related adverse side effects.

      The Company is focusing its research and development on (i) expansion of
the ISV-900 technology for the prognosis, diagnosis and management of glaucoma,
(ii) providing on-going technical support to P&U for ISV-205 for the treatment
of inflammation and the prevention and treatment of glaucoma, (iii) ISV-615 for
the treatment of diabetic retinopathy and macular degeneration, (iv) ISV-014 a
retinal drug delivery device, and (v) evaluation and development of several
antibiotics not currently used in ophthalmics.

      To date, InSite Vision has not received any revenues from the sale of
products, although it has received a small amount of royalties from the sale of
products using the Company's licensed technology. Until 1999, the Company had
been unprofitable since its inception 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.

      On January 28, 1999, the Company entered into a license agreement and
stock purchase agreement pursuant to which InSite granted P&U an exclusive
worldwide license to ISV-205 for the treatment of glaucoma. The license called
for (i) P&U to assume responsibility for the development of the product upon
completion by InSite of, among other activities, Phase II studies completed by
the Company, (ii) P&U to reimburse InSite for research and development expenses
and to make payments to InSite for on-going technical support, and (iii) the
payment by P&U to InSite of royalties on product sales should ISV-205 be
successfully commercialized. InSite will continue to bear responsibility for the
prosecution and maintenance of the patents subject to the license, among other
things. The transaction also called for equity investments from P&U of
$3,500,000 for which they received 1,942,419 shares of common stock, with the
potential for future equity investments at an average of prevailing market
prices if the Company achieves certain milestones.

      On November 11, 1999, the Company entered into a license agreement, stock
purchase agreement and credit agreement pursuant to which InSite granted P&U an
exclusive worldwide royalty-bearing license to its ISV-900 technology for
diagnostic, prognostic and therapeutic applications in the area of glaucoma. The
license calls for (i) P&U to pay the Company a $5 million licensing fee, (ii)
P&U to make up to $5 million in research and development payments to the Company
over three years starting in 2000, (iii) P&U to pay the Company royalties on
product sales should any products be successfully commercialized from this
technology, and (iv) the potential for payments of up to $3 million by P&U to
the Company based on achievement of certain milestones.

      The stock purchase agreement provided for a $2.0 million equity investment
by P&U in the Company. A total of 723,195 shares were purchased in January 2000,
45 days after the execution of the agreement. The stock purchase agreement also
provides for a standstill period of thirty (30) months during which P&U and its
subsidiaries will not purchase additional shares of the Company, other than
those provided for under any existing agreements between the companies, without
the prior written consent of



                                       33
<PAGE>   32

the Company. This standstill period will terminate earlier if certain actions
are taken by other parties to acquire more than a 9.99% interest in the stock of
the Company or if any other party announces their intention to assume control of
the Company, whether by tender offer, merger, proxy contest or otherwise.

      The credit agreement provides for a $4.0 million revolving line of credit
to be made available to the Company on November 11, 2001 for a period of three
(3) years. Any amounts drawn on the line will bear interest at a rate of three
percent (3%) over the prime rate announced at the time of borrowing by Chase
Manhattan Bank in New York City. At the Company's discretion, repayments on the
line may be made in cash at any point, or the total amount due at the end of the
loan period may be paid by issuance of the Company's stock at a twenty-five
percent (25%) premium to the average market price of the Company's stock for a
period prior to the end of the loan. The loan provides for certain affirmative
and negative covenants as well as other terms and conditions.

      In August 1999, the Company entered into a license agreement with SSP Co.,
Inc., a Japanese company, to be the exclusive manufacturer and distributor of
AquaSite in Japan. AquaSite is an over-the-counter product which uses the
Company's DuraSite technology and demulcents for the symptomatic treatment of
dry eye. Under this agreement, the Company received a net amount of $3,000 for
materials provided to SSP during 1999.

      In March 1999, the Company entered into a royalty-bearing license
agreement with Global Damon, a Korean company, to be the exclusive distributor
of AquaSite in the Republic of Korea. Concurrently, the Company entered into a
manufacturing agreement with Kukje, a Korean company, to produce the AquaSite to
be sold by Global Damon.

      As of December 31, 1999, the Company's accumulated deficit was
approximately $84.8 million. There can be no assurance that InSite Vision will
ever achieve or be able to maintain either significant revenues from product
sales or profitable operations.


RESULTS OF OPERATIONS

      The Company had total net revenues of $4.8 million, $16,000 and $50,000
for the years ended December 31, 1999, 1998 and 1997, respectively. The increase
from 1998 to 1999 was attributable to the license fee received from P&U in 1999.
The Company earned royalty income of $10,000, $16,000 and $50,000 for the years
ended December 31, 1999, 1998 and 1997, respectively, from sales of AquaSite by
CIBA Vision. To date, the Company has not relied on royalty revenues to fund its
activities, nor has it received revenues from the sale of products.

      Research and development expenses, net, decreased 77% to $1.4 million in
1999 from $6.2 million in 1998 and decreased 14% in 1998 from $7.2 million in
1997. The decrease in 1999 was primarily due to expense recovery from P&U of
$4.2 million related to the ISV-205 project. Additionally, compensation and
related costs decreased due to a reduction in R&D headcount which occurred in
November 1998. The decrease in 1998 was primarily due to lower expenditures for
outside services, consultants and compensation-related costs due to a reduction
in R&D headcount. The reduction in outside service costs mainly reflects the
completion of development activities for ISV-208 and transfer of the project to
B&L, the Company's joint development partner on that project.

      General and administrative expenses decreased 15% in 1999 to $2.3 million
from $2.7 million in 1998 and decreased 10% during 1998 from $3.0 million in
1997. The decrease in 1999 as compared to 1998 was primarily due to lower
personnel related and facility costs. The lower facility cost reflected the
sublease of a portion of unused office space beginning in January 1999. The
sublease term is consistent with the base lease which is through 2001. The
decrease in 1998 as compared to 1997 was primarily related to the reduced cost
of directors and officers' insurance, lower consulting expenses and lower costs
related to the hiring of full time personnel in the area of accounting and
finance.



                                       34

      Net interest and other income was $85,000, $299,000 and $390,000 in 1999,
1998 and 1997, respectively. These fluctuations are due principally to changes
in average cash balances. Interest earned in the future will be dependent on the
Company's funding cycles and prevailing interest rates. Interest expense in 1997
related to notes payable which were paid off during the first quarter of 1997.

      The Company had net income for the year ended December 31, 1999 of $1.1
million and incurred net losses of $8.6 million and $9.8 million for the years
ended December 31, 1998 and 1997, respectively. The net income in 1999 is mainly
the result of licensing revenue of $4.8 million and cost reimbursement of $4.2
million received from P&U for the ISV-900 and ISV-205 projects, respectively.

LIQUIDITY AND CAPITAL RESOURCES

      Through 1995, InSite Vision financed its operations primarily through
private placements of preferred stock totaling approximately $32 million and an
October 1993 initial public offering of Common Stock, which resulted in net
proceeds of approximately $30 million. After 1995, the Company financed its
operations primarily through a January 1996 private placement of Common Stock
and warrants resulting in net proceeds of approximately $4.7 million and an
April 1996 public offering which raised net proceeds of approximately $8.1
million. In accordance with a July 1996 agreement between the Company and B&L,
the Company received a total of $2.0 million from the sale of Common Stock in
August 1996 and 1997. In September 1997, the Company completed a $7.0 million
private placement of 7,000 shares of redeemable convertible Series A Preferred
Stock resulting in net proceeds of approximately $6.5 million. In January 1999,
the Company entered into a transaction with P&U from which the Company received
a total of $3.5 million from the sale of Common Stock in January and September.
In November 1999, the Company entered into another transaction with P&U from
which the Company received a $5.0 million licensing fee and, in January 2000,
received $2.0 million from the sale of 723,195 shares of Common Stock. At
December 31, 1999, the Company had cash and cash equivalents totaling $6.7
million. It is the Company's policy to invest these funds in highly liquid
securities, such as interest bearing money market funds, Treasury and federal
agency notes and corporate debt.

      For the year ended December 31, 1999, cash provided by operating
activities, less cash used to acquire capital equipment, was $1.8 million and
for the years ended December 31, 1998 and 1997, cash used for operating
activities and additions to capital equipment was $7.8 million and $9.4 million,
respectively. Of those amounts, $88,000, $25,000 and $709,000 were for additions
to laboratory and other property and equipment in 1999, 1998 and 1997,
respectively. In 1997, $645,000 of the additional expenditures related to the
Company's portion of improvements at B&L's facilities in Tampa, Florida. In
1999, the Company sold the equipment and improvements at the Tampa facility to
B&L for $410,000, which resulted in a loss on the sale of $107,000. In 1998, the
Company had recognized an impairment in the value of this equipment of $87,000.
This also resulted in a decrease in 1998, in both laboratory and other equipment
and accumulated depreciation of $764,000.

      The Company's future capital expenditures and requirements will depend on
numerous factors, including the progress of its research and development
programs and 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 businesses,
products and technologies, the completion of commercialization activities and
arrangements, the timing of additional product development and the purchase of
additional property and equipment. Starting in 1997, the Company wrote-off its
fully depreciated assets. This resulted in a decrease in both property and
equipment and accumulated depreciation of $0.3 million, $1.3 million and $3.4
million in 1999, 1998 and 1997, respectively, with no change in net property and
equipment.

      The Company anticipates no material capital expenditures to be incurred
for environmental



                                       35
<PAGE>   34

compliance in fiscal year 2000. 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 cash equivalents, in combination
with the cash the Company has received and will receive during 2000 as part of
the ISV-900 and ISV-205 licensing transactions with P&U, will be sufficient to
meet its operating expenses and cash requirements through 2000. InSite Vision
may require substantial additional funds prior to reaching sustained
profitability, and the Company may seek private or public equity investments,
future collaborative agreements, and possibly research funding to meet such
needs. Even if the Company does not have an immediate need for additional cash,
it may seek access to the private or public equity markets if and when it
believes conditions are favorable. There is no assurance that such additional
funds will be available for the Company to finance its operations on acceptable
terms, or at all.

YEAR 2000

      The Year 2000 ("Y2K") issue was the result of computer programs using a
two-digit format, as opposed to four digits, to indicate the year. It was
anticipated that such computer systems would be unable to interpret dates beyond
the year 1999, which could cause a system failure or other computer errors,
leading to disruptions in operations.

      The Company implemented a program to assess its exposure from Y2K related
failures in its internal systems. Prior to December 31, 1999, the Company had
determined that the majority of the Company's significant operating and
accounting systems were Y2K compliant.

      The Company did not encounter any system failures or other computer errors
related to a Y2K issue and did not suffer any interruption in service from its
suppliers or vendors. The Company has incurred less than $25,000 in expense to
upgrade or replace non-compliant computer programs or hardware. However, there
can be no assurance that the Company's eventual Y2K related costs will not
exceed this amount. While the Company does not have a comprehensive program for
monitoring whether its suppliers' and vendors' systems were or are Y2K
compliant, it does not believe that non-compliance by and single source provider
would have a material impact on its operations. The Company does not expect its
financial condition or results of operations to be materially adversely affected
by Y2K issues.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

      The following discusses the Company's exposure to market risk related to
changes in interest rates.

      The Company invests its excess cash in investment grade, interest-bearing
securities. At December 31, 1999, the Company had $6.7 million invested in money
market mutual funds. While a hypothetical decrease in market interest rates by
10 percent from the December 31, 1999 levels would cause a decrease in interest
income, it would not result in a loss of the principal. Additionally, the
decrease in interest income would not be material.

REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Stockholders
InSite Vision Incorporated

We have audited the accompanying consolidated balance sheets of InSite Vision
Incorporated as of December 31, 1999 and 1998, and the related consolidated
statements of operations, stockholders' equity (deficit) and cash flows for each
of the three years in the period ended December 31, 1999. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of InSite
Vision Incorporated at December 31, 1999 and 1998, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally
accepted in the United States.

                           INSITE VISION INCORPORATED

                   Notes to Consolidated Financial Statements
                                December 31, 1999


1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Presentation. The accompanying consolidated financial statements
include the accounts of InSite Vision and its wholly-owned United Kingdom
subsidiary, InSite Vision Limited. InSite Vision Incorporated (the "Company" or
"InSite Vision") operated in one segment and is focused on ophthalmic genetics
and developing ophthalmic drugs and ophthalmic drug delivery systems. InSite
Vision Limited was formed for the purpose of holding and licensing intellectual
property rights. All intercompany accounts and transactions have been
eliminated.

      Until 1999, the Company had incurred losses since its inception. The
Company expects to incur substantial additional development costs prior to
reaching sustained profitability, including costs related to clinical trials and
manufacturing expenses. As a result, the Company will require substantial
additional funds, and until sufficient royalties are generated from sales of the
Company's licensed products, the Company may seek collaborative agreements,
research funding, and private or public equity or debt investments to meet such
needs. If such funds are not available, management may need to reassess its
plans. Even if the Company does not have an immediate need for additional cash,
it may seek access to the private or 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.

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

      Cash and Cash Equivalents. The Company invests its excess cash in
investment grade, interest-bearing securities. As of December 31, 1999 and 1998,
cash equivalents consisted of money market and mutual funds. All cash and cash
equivalents are stated at fair market value. The Company considers highly liquid
investments with original maturities of three months or less as cash
equivalents.

      Property and Equipment. Property and equipment is stated at cost, less
accumulated depreciation. Depreciation of property and equipment is provided
over the estimated useful lives of the respective assets, which range from three
to five years, using the straight-line method. Leasehold improvements are
amortized over the lives of the related leases or their estimated useful lives,
whichever is shorter, using the straight-line method. It is the Company's policy
to write-off its fully depreciated assets. This resulted in a decrease in both
property and equipment and accumulated depreciation in 1999 and 1998 of $0.3
million and $1.3 million, respectively, with no change in net property and
equipment.

      In accordance with FASB Statement No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company
records impairment losses on long-lived assets used in operations when events
and circumstances indicate that the assets might be impaired and the
undiscounted cash flows estimated to be generated by those assets are less than
the carrying amounts of those assets. During 1998, the Company evaluated certain
assets and determined that assets with a carrying value of $946,000 were
impaired and reduced their carrying value by $87,000. This loss is included in
the 1998 research and development expense in the Consolidated Statements of
Operations. In July 1999, the Company sold this equipment and recorded a loss of



                                       50
<PAGE>   45

$107,000 which is included in the 1999 research and development expense in the
Consolidated Statements of Operations.

      Earnings (Loss) per Share. Basic and diluted net income (loss) per share
information for all periods is presented under the requirement of SFAS No. 128,
"Earnings per Share." Basic earnings per share has been computed using the
weighted-average number of common shares outstanding during the period, and
excludes any dilutive effects of stock options and convertible securities.
Potentially dilutive securities have been excluded from the computation of
diluted net loss per share in 1998 and 1997, as their inclusion would be
antidilutive.

The following table sets forth the computation of basic and diluted earnings
(loss) per share:

=====================================================================================================
</TABLE>

      Due to the loss from operations, earnings (loss) per share for 1998 and
1997 is based on the weighted average number of common shares only, as the
effect of including equivalent shares from stock options would be anti-dilutive.
If the Company had recorded net income, the calculation of earnings per share
would have included approximately an additional 2,186,000 and 1,193,000 common
equivalent shares related to the outstanding stock options and warrants
(determined using the treasury stock method) and convertible preferred stock
(using the if-converted method) for 1998 and 1997, respectively.

      Accounting for Employee Stock Options. The Company accounts for stock
options granted to employees and directors in accordance with Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees" and, accordingly, does not recognize compensation expense for options
granted to employees and directors at an exercise price equal to the fair value
of the underlying common stock.

      Accounting for Stock Options Exchanged for Services. The Company issues
stock options to consultants of the Company in exchange for services. The
Company has valued these options using the Black-Scholes option valuation model
at each reporting period and has recorded charges to operations over the vesting
periods of the individual stock options. Such charges amounted to approximately
$194,000, $155,000 and $118,000 in 1999, 1998 and 1997, respectively.

      Accounting for Materials Purchased for Research and Development. The
Company expenses materials for research and development activities when the
items are purchased.



                                       51
<PAGE>   46

      Accounting for Cost Sharing Agreements. The Company directly reduces
expenses for amounts reimbursed pursuant to cost sharing agreements. During 1999
and 1998, research and development expenses were reduced by $4,248,000 and
$361,000, respectively, for costs reimbursed by Pharmacia & Upjohn (P&U) and
Bausch and Lomb Pharmaceuticals, Inc. (B&L) under the terms of the
collaborations described in Note 2.

      Key Suppliers. The Company is dependent on single or limited source
suppliers for certain materials used in its research and development activities.
The Company has generally been able to obtain adequate supplies of these
components. However, an extended interruption in the supply of these components
currently obtained from single or limited source suppliers could adversely
affect the Company's research and development efforts.

      The Company obtains batimastat, the active ingredient for its ISV-615
product candidate, from British Biotech. In December 1996, British Biotech
advised the Company that it had discontinued its own development and
manufacturing of batimastat. The Company is currently negotiating with British
Biotech to license the compound and obtain access to on-going drug supply.
Inability to obtain a license would adversely affect the Company's ability to
continue the ISV-615 development program.

      Revenue Recognition. Non-refundable technology license fees are recognized
as revenues when received and when all contractual obligations of the Company
relating to the fees have been fulfilled, evidence of an arrangement exists, the
fee is fixed and determinable and collectibility is reasonably assured.

2.    LICENSES

      In December 1999, the Company entered into an exclusive worldwide license
agreement with INSERM for the diagnostic, prognostic and therapeutic uses of a
gene for chronic open angle glaucoma. The Company has paid a licensing fee and
will make royalty payments on future product sales, if any.

      On November 11, 1999, the Company entered into a license agreement, stock
purchase agreement and credit agreement pursuant to which InSite granted P&U an
exclusive worldwide royalty-bearing license to its ISV-900 technology for
diagnostic, prognostic and therapeutic applications in the area of glaucoma. The
license calls for (i) P&U to pay the Company a $5 million licensing fee, (ii)
P&U to make up to $5 million in research and development payments to the Company
over three years starting in 2000, (iii) P&U to pay the Company royalties on
product sales should any products be successfully commercialized from this
technology, and (iv) payments of up to $3 million by P&U to the Company if
certain milestones are achieved.

      P&U is receiving rights to sub-license all development work on ISV-900
completed as of November 11, 1999, which includes rights to certain genes, a
diagnostic test, a database and access to other data relating to these genes.
The Company expects that these rights will translate into 3 products - one for
indications of more severe forms of glaucoma, one for detecting the possibility
of developing glaucoma and one for diagnosing glaucoma in infants. These
products are ready for commercialization by P&U.



                                       52
<PAGE>   47

      The additional research and development payments of $5 million are to be
used for further development of the ISV-900 technology. This R&D work will
include searching for additional gene mutations as well as gathering information
for the development of possible therapeutic products based on the genetic data.
The result of this work could be further enhancements to the products currently
ready for commercialization as discussed above, which would be released
separately, or additional products altogether. This work is not essential to the
products currently ready for commercialization by P&U.

      The Company recognized $4.8 million as license revenue during the fourth
quarter of 1999, due to the persuasive evidence of the existence of an
arrangement, delivery had occurred, the fee was fixed and determinable and
collectibility was reasonably assured. The technology represented a separate
element of the arrangement that was recognized when the technology was delivered
to P&U for commercialization.

      The stock purchase agreement provided for a $2.0 million equity investment
by P&U in the Company. A total of 723,195 shares were purchased in January 2000,
45 days after the execution of the agreement. The stock purchase agreement also
provides for a standstill period of thirty (30) months during which P&U and its
subsidiaries will not purchase additional shares of the Company, other than
those provided for under any existing agreements between the companies, without
the prior written consent of the Company. This standstill period will terminate
earlier if certain actions are taken by other parties to acquire more than a
9.99% interest in the stock of the Company or if any other party announces their
intention to assume control of the Company, whether by tender offer, merger,
proxy contest or otherwise.

      The credit agreement provides for a $4 million revolving line of credit to
be made available to the Company on November 11, 2001 for a period of three (3)
years. Any amounts drawn on the line will bear interest at a rate of three
percent (3%) over the prime rate announced by Chase Manhattan Bank in New York
City. At the Company's discretion, repayments on the line may be made in cash at
any point, or the total amount due at the end of the loan period may be paid by
issuance of the Company's stock at a twenty-five percent (25%) premium to the
average market price of the Company's stock for a period prior to the end of the
loan. The loan provides for certain affirmative and negative covenants as well
as other terms and conditions.

      In August 1999, the Company entered into a license agreement with SSP Co.,
Inc., a Japanese company, to be the exclusive manufacturer and distributor of
AquaSite in Japan. AquaSite is an over-the-counter product which uses the
Company's DuraSite technology and demulcents for the symptomatic treatment of
dry eye. Under this agreement, the Company received a net amount of $3,000 for
materials provided to SSP during 1999.

      In March 1999, the Company entered into a royalty-bearing license
agreement with Global Damon, a Korean company, to be the exclusive distributor
of AquaSite in the Republic of Korea. Concurrently, the Company entered into a
manufacturing agreement with Kukje, a Korean company, to produce the AquaSite to
be sold by Global Damon.

      On January 28, 1999, the Company entered into a license agreement and
stock purchase agreement pursuant to which InSite granted P&U an exclusive
worldwide license to ISV-205 for the treatment of glaucoma. The license calls
for (i) P&U to assume responsibility for the development of the product upon
completion by the Company of, among other activities, Phase II studies currently
being conducted by the Company, (ii) P&U to reimburse InSite for certain
research and development expenses and make payments to InSite for on-going
technical support, and (iii) the payment by P&U to InSite of royalties on
product sales should ISV-205 be successfully commercialized. InSite will
continue to bear responsibility for the prosecution and maintenance of the
patents subject to the license, among other things. The transaction also called
for equity investments from P&U of $3,500,000 for which they received 1,942,419
shares of common stock in February and September 1999, with the potential for
future equity investments based on achievement of certain milestones.

      The Company has a license agreement with CIBA Vision, an ophthalmic
company which is an affiliate of



                                       53
<PAGE>   48

CIBA-GEIGY Limited. Under the terms of the agreement, CIBA Vision has
co-exclusive rights to manufacture and market AquaSite and ToPreSite in the U.S.
and AquaSite in Canada. The license agreement requires CIBA Vision to pay
royalties on net sales of the licensed products. The Company recognized $10,000,
$16,000 and $50,000 of royalty revenue for sales of AquaSite in 1999, 1998 and
1997, respectively.

3.    LEASE COMMITMENTS

      The Company leases its facilities under noncancelable operating lease
agreements that expire in 2001. Rent expense was $431,000, $514,000 and $497,000
for 1999, 1998 and 1997, respectively. The 1999 rent expense reflects $63,000
received by the Company related to the January 1999 sublease of a portion of the
Company's facility. The sublease continues through the term of the Company's
operating lease and provides for annual payments of $64,000 in 2000 and 2001. As
of December 31, 1999, the aggregate future minimum payments under noncancelable
leases, not considering amounts to be received under subleasing agreements, are:

      The valuation allowance decreased by $54,000 and increased $3.3 million
during the years ended December 31, 1999 and 1998, respectively.

      At December 31, 1999, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $66.0 million, which expire in the
years 2001 through 2018 and net operating loss carryforwards for state income
tax purposes of approximately $29.0 million which expire in the years 1999
through 2003. The Company also has federal and state research and development
credit carryforwards of approximately $2.0 million



                                       54

and $1.0 million, respectively, which expire in the years 2001 through 2013.

      Utilization of the Company's federal and state net operating loss
carryforwards and research and development tax credits are subject to an annual
limitation against taxable income in future periods due to the ownership change
limitations provided by the Internal Revenue Code of 1986. As a result of this
annual limitation, a significant portion of these carryforwards will expire
before ultimately becoming available for offset against taxable income.
Additional losses and credits will be subject to limitation if the Company
incurs another change in ownership in the future.

5.    REDEEMABLE PREFERRED STOCK

      In September 1997, the Company received net proceeds of approximately $6.5
million from a private placement of 7,000 shares of Series A Convertible
Preferred Stock with a $0.01 par value ("Series A Preferred"). The number of
shares of Common Stock issuable upon conversion of the Series A Preferred is
equal to the face value of each share of Series A Preferred divided by the lower
of the fixed conversion price of $2.127 or a variable conversion price. The
variable conversion price is determined by applying a discount, which ranged
from 10% for shares converted prior to June 10, 1998, to 17.5% for shares
converted after December 7, 1998, to an average of closing bid prices of the
Company's common stock at the time of conversion. Such conversion prices are
subject to adjustment in accordance with the terms of the Certificate of
Designations, Preferences and Rights of the Series A Preferred. The value of the
Series A Preferred shares to be converted will also include a 6% per annum
premium which accrues from the date of issuance until the date of conversion.
Three years after issuance, any remaining unconverted preferred shares will
automatically be converted into common stock. As of December 31, 1999, all of
the outstanding shares of Series A Preferred have been converted into 5,061,213
shares of common stock. The Company also issued a warrant to purchase 70 shares
of Series A Preferred that is subject to the same conversion terms and premium
as described above, which is still outstanding as of December 31, 1999. Holders
of the Series A Preferred have no voting rights, except as required by
applicable Delaware law. The Company has authorized 5,000,000 shares of
Preferred Stock, 7,070 of which have been designated Series A Preferred.
Pursuant to the agreement, 6,000,000 shares of common stock have been reserved
for issuance to the holders of the Series A Preferred of which 938,787 shares
remain reserved at December 31, 1999.

      For the years ended December 31, 1999, 1998 and 1997, in accordance with
SEC Rules and Regulations, the Company reported non-cash preferred dividends of
$22,000, $514,000 and $1,326,000, respectively. The dividends are related to the
discount at which Series A Preferred could be converted to common stock and the
6% per annum premium, payable in additional common stock, earned on the
outstanding Series A Preferred Stock. The dividends are used to determine the
net loss per share applicable to common stockholders.

      The following table summarizes information concerning the issuance and
conversion of the Series A Preferred Stock (in thousands):

      The weighted average grant date fair values of options granted during
1999, 1998 and 1997 was $1.28, $2.26 and $3.58, respectively.

      Pursuant to the terms of the 1994 Stock Plan, generally each non-employee
director who is newly elected or appointed after October 25, 1993, is granted an
option to purchase 10,000 shares of common stock at a price per share equal to
the fair market value of the common stock on the grant date. Each continuing
non-employee director also receives an annual grant of an option to purchase
10,000 shares. Such options vest one year after the grant date.

      The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25), and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, because the exercise price of the Company's
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recognized.

      The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting requirements
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

      Pro forma information regarding net loss and loss per share is required by
Statement 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that Statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1999,
1998 and 1997, respectively: risk-free interest rates ranging from 4.64% to
6.87%; volatility factors for the expected market price of the Company's common
stock of 1.15, 1.08 and 0.89; and a weighted-average expected life for the
options of 4 years.

      For purposes of pro forma disclosure, the estimated fair value of the
options is amortized to expense over the vesting period of the related options.
The Company's pro forma information follows (in thousands except for loss per
share information):

grants.


Employee Stock Purchase Plan.

      On April 1, 1994, employees of the Company began participating in an
Employee Stock Purchase Plan which provides the opportunity to purchase Common
Stock at prices not more than 85% of market value at the time of purchase.
During the years ended December 31, 1999, 1998 and 1997, respectively, 19,577,
27,195 and 13,370 shares of Common Stock were issued pursuant to this plan. At
December 31, 1999, an additional 19,577 shares are reserved for issuance under
this plan. The effects of this plan on the pro forma disclosures above are not
material.

                          PAYMENTS, REPORTS AND RECORDS

        SECTION 3.1   SUBLICENSE FEE.

               (a) In consideration of the sublicenses and rights granted by
        InSite to P&U hereunder, P&U shall pay to InSite, within five (5)
        Business Days after the Effective Date, the sum of Five Million Dollars
        * ("Sublicense Fee") in United States currency by wire transfer to an
        account designated by InSite, less the sum of * that P&U shall be
        credited on account of such amount being paid by P&U to InSite upon
        execution of the letter of intent related hereto.

               (b) InSite has determined, in the exercise of its obligations to
        the parties to the ISV-900 Agreements, that the Sublicense Fee shall be
        allocated as follows: * for the rights related to TIGR gene and the
        Apolipoprotein E gene, * for the CYP1B1 gene, and * for all other
        sublicenses and rights granted herein.

        SECTION 3.2 R&D PAYMENTS. In further consideration of InSite's grant of
rights to P&U hereunder, including the licenses set forth in Article 2, and
subject to the terms and conditions of this Agreement, P&U will pay InSite as

               (a) * in United States currency by wire transfer to an account
        designated by InSite, on *.

               (b) * in United States currency by wire transfer to an account
        designated by InSite, on *.

               (c) * in United States currency by wire transfer to an account

               (d) Subject to Section 4.1(b), InSite shall devote and use the
        research and development payments received under this Section 3.2 solely
        for the purpose of covering internal and external costs associated with
        further developing the ISV-900 Technology.

               (e) Any additional research and development payments related to
        the commercialization of the Product shall be determined by the
        Development Committee. The failure of the Development Committee to agree
        on any additional research and development payments shall not affect or
        impair the rights granted to P&U hereunder.

        SECTION 3.3   MILESTONE PAYMENTS.

               (a) If the Development Committee or Executive Committee, pursuant
        to Section 4.1 or 4.2, as the case may be, determines within * of the
        Effective Date, that the milestone described in Schedule 3.3(a) (the
        "First Milestone") has been achieved, P&U shall pay InSite within five
        (5) Business Days of receiving written notice of such

        determination, the sum of * in United States currency by wire transfer
        to an account designated by InSite.

               (b) If the Development Committee or Executive Committee, pursuant
        to Section 4.1 or 4.2, as the case may be, determines within * of the
        Effective Date, that the milestone described in Schedule 3.3(b) (the
        "Second Milestone") has been achieved, P&U shall pay InSite the sum of *
        in United States currency by wire transfer to an account designated by
        InSite.

        SECTION 3.4   ROYALTY.

               (a) In further consideration of the sublicensing of InSite's
        rights under the ISV-900 Agreements by InSite to P&U, P&U shall pay to
        InSite a royalty in the amount of * of Net Sales of the Product to Third
        Parties (the "Patent Royalty") in each country in the Territory wherein
        the manufacture, use, processing, importation, distribution, detailing
        or sale of the Product would infringe any filed ISV-900 Patent. In the
        event that (i) InSite (or any other party to an ISV-900 Agreement with
        obligations to pursue patent rights) abandons or fails to diligently
        pursue any filed ISV-900 Patent in a country of the Territory, (ii) any
        filed ISV-900 Patent is subsequently disallowed in a country of the
        Territory, or (iii) a product, which competes with the Product, is sold
        in a country in the Territory in which an ISV-900 Patent has been filed
        but not yet issued, and such competition results in the competing
        product obtaining a market share in excess of * of the total market for
        the Product as determined in any calendar quarter in such country, then
        P&U shall have no obligation to pay InSite a Patent Royalty in any such
        country for such quarter. Unless this Agreement is otherwise terminated
        earlier, P&U's Patent Royalty will automatically expire on a
        country-by-country basis on the expiration (or revocation) of the last
        to expire (or to be revoked) of the ISV-900 Patents in each country.
        Upon the expiration of the Country Term based upon expiration (or
        revocation) of the last to expire (or to be revoked) of the ISV-900
        Patents in such country, P&U shall have a fully paid, non-revocable,
        non-exclusive license under the ISV-900 Know-How in that country to
        promote, import, market and sell the Products for use in the Field.

               (b) In further consideration of the sublicensing of InSite's
        rights under the ISV-900 Agreements by InSite to P&U, including the
        rights to InSite Know-How, P&U shall pay to InSite a royalty in the
        amount of * of Net Sales of the Product to Third Parties (the "Know-How
        Royalty") in each country in the Territory wherein P&U is not subject to
        the Patent Royalty. Upon filing of an ISV-900 Patent in any country
        wherein P&U is paying a Know-How Royalty, P&U shall pay the Patent
        Royalty. Notwithstanding anything to the contrary in this Section
        3.4(b), in the event that a product that competes with the Product (i.e.
        a product with substantially the same diagnostic or prognostic
        capabilities or the same active ingredient and dosage strength as the
        Product) is marketed by a Third Party in any country in the Territory
        wherein P&U is subject to the Know-How Royalty, the Know-How Royalty
        shall be reduced by * of the amount that would otherwise be payable.
        Notwithstanding anything herein to the contrary, unless this Agreement
        is otherwise terminated earlier, P&U's obligation to

        pay the Know-How Royalty in a country in which P&U is paying the
        Know-How Royalty, shall expire on the * of the First Commercial Sale of
        the Product in such country by P&U. Upon such date, P&U shall have a
        fully paid, non-revocable, non-exclusive license under the ISV-900
        Know-How in that country to promote, import, market and sell the
        Products for use in the Field.

               (c) InSite shall remain obligated for any and all payment
        obligations under the ISV-900 Agreements during the terms thereof.
        InSite shall pay all royalties arising under the ISV-900 Agreements out
        of the Patent Royalty and/or Know-How Royalty in a timely manner,
        consistent with the terms of each of the ISV-900 Agreements.

        SECTION 3.5   METHOD AND MANNER OF ROYALTY PAYMENTS.

               (a) P&U shall deliver to InSite within forty-five (45) days
        following the end of each Payment Period a written report (the "Payment
        Statement") describing (i) the Net Sales of the Product sold during such
        Payment Period in each country wherein P&U is obligated to pay InSite a
        Royalty hereunder; (ii) the calculation of Net Sales from the gross
        revenues for the Product in each such country, including without
        limitation, a breakdown of each deduction from gross sales; and (iii)
        the Royalty due on the sales of the Product for such Payment Period. P&U
        shall pay to InSite within forty-five (45) days following the end of
        each Payment Period any Royalty due and payable to InSite in accordance
        with this Article 3. Each such payment shall be accompanied by a Payment
        Statement.

               (b) All payments to be made by P&U to InSite pursuant to this
        Agreement shall be made in U.S. Dollars. Net Sales outside the U.S.
        shall be first determined in the currency of the country in which they
        are earned and shall be converted quarterly into an amount in U.S.
        Dollars based on P&U's internal exchange rates used in preparing P&U's
        consolidated earnings statements for such quarter. All such converted
        Net Sales shall be consolidated with U.S. Net Sales for the
        corresponding period and the applicable royalty payable determined
        therefrom.

               (c) Any Royalty due and payable to InSite pursuant to this
        Agreement shall be made by wire transfer, to such bank or account as
        InSite may from time to time designate in writing. All Royalties shall
        be made in United States Dollars and shall be considered to be made as
        of the day on which it is received in InSite's designated bank account.

               (d) Whenever any Royalty is due on a day which is not a Business
        Day, such payment shall be made on the immediately succeeding Business
        Day.

        SECTION 3.6 THIRD PARTY ROYALTIES. In the event that P&U, its Affiliates
and/or its Sublicensees is or are required to obtain a license from a Third
Party in order to practice the rights granted under the ISV-900 Patents or
ISV-900 Know-How in a country in the Territory (the "Third Party Licenses"),
then P&U shall be entitled to reduce the amount of the Royalty payable under
Section 3.4 by the amount of any consideration, including but not limited to
royalties, actually paid to a Third Party under such Third Party License by P&U,
its Affiliates or Sublicensees but in no event shall the Patent Royalty paid to
InSite be less than *

<PAGE>   14
* nor shall the Know-How Royalty paid to InSite be less than * in the absence of
  competition or * with competition. This provision shall not be applicable to
  arrangements or agreements which are determined to constitute ISV-900
  Agreements after the Effective Date.

        SECTION 3.7   AUDIT.

               (a) Each Party shall have the right to audit the records of the
        other Party, at its own expense; provided, however, that if any
        discrepancy exceeds five percent (5%), the cost and expenses of such
        audit shall be paid by the Party against whom the discrepancy is found,
        using a mutually acceptable nationally recognized firm of independent
        certified accountants. Such accountants will have access, on reasonable
        notice to such Party's and to its Affiliates' records, as the case may
        be, during reasonable business hours for the purpose of verifying any
        royalty payable under this Agreement or under the ISV-900 Agreements for
        the two preceding years, or verifying that InSite's use of the payments
        received under Section 3.2 were devoted and used by InSite solely to
        further develop the ISV-900 Technology. Notwithstanding the foregoing,
        this right may not be exercised more than twice in any calendar year.
        The accountant shall provide both InSite and P&U with a copy of any
        report prepared as a result of the audit.

               (b) Each Party agrees to hold confidential all information
        learned in the course of any examination of the other Party's books and
        records hereunder, except when it is necessary for such Party to reveal
        such information in order to enforce its rights under this Agreement or
        when otherwise compelled by law.

               (c) With respect to the Royalty calculations or InSite's use of
        payments received under Section 3.2, all reports and payments not
        disputed as to correctness within two (2) years after receipt thereof
        shall thereafter conclusively be deemed correct for all purposes. With
        respect to any amounts payable under any ISV-900 Agreement, all reports
        and payments not disputed as to correctness within the periods provided
        under such agreement shall thereafter conclusively be deemed correct for
        all purposes.

        SECTION 3.8 PAYMENT ADJUSTMENTS. Any adjustment (whether payment or
reimbursement, as the case may be) required as a result of an audit conducted
pursuant to Section 3.7 shall be made within ten (10) Business Days after the
date on which the accountant conducting the audit issues a written report to
InSite and P&U containing the results of the audit.

        or testing, or (B) any preclinical or clinical development.

               (c) The Development Committee shall operate consistent with the
        procedures set forth (i) herein and (ii) in Sections 3.3(c) and (e) of
        the ISV-205 Agreement, which are attached as Schedule 4.1.

               (d) InSite shall, at the direction of the Development Committee,
        take any and all actions in any and all matters arising under the

        majority vote. In the event of a deadlock on any matter to be decided by
        the Development Committee, the decision shall be made by the chairperson
        of the Development Committee; provided, however, that in the event of a
        deadlock solely with respect to future expenditures of R&D payments
        under Section 3.2 or whether either of the milestones described in
        Sections 3.3(a) and (b) have been reached, the chairperson of the
        Development Committee shall not have the right to cast the deciding vote
        but shall instead refer the issue to the Executive Committee.

               (f) Each Party will bear its own costs and expenses associated
        with participation in the Development Committee, and each Party may
        change its Development Committee members upon notice to the other Party.

        SECTION 4.3 ISV-900 FILES. Upon the Effective Date, InSite shall
transfer to P&U copies of all files related to the ISV-900 Agreements, the
ISV-900 Technology and the Product; provided, however, that InSite will retain a
copy of such files for its use consistent with the terms of this Agreement. P&U
shall be solely responsible for preparing applications and for seeking and, if
granted, maintaining Product registrations and regulatory approval in the
Territory, including performing any and all studies required by the governing
regulatory authorities from time to time to obtain and maintain such
registration and regulatory approval for the Product.

each agree to take reasonable actions, consistent with efforts used by each

                                 INDEMNIFICATION

        SECTION 9.1 INDEMNIFICATION BY INSITE. Except as otherwise specifically
provided herein, InSite shall indemnify and hold harmless P&U and its officers,
directors, agents, employees, Affiliates, and Sublicensees against all claims,
actions, losses, damages, costs, expenses (including court costs and legal fees
on a full indemnity basis) or other liabilities net of any tax benefit
("Liabilities") whatsoever in respect of the breach by InSite of its
representations, warranties or default of any of its obligations contained in
this Agreement.

        SECTION 9.2 INDEMNIFICATION BY P&U. Except as otherwise specifically
provided herein, P&U shall indemnify and hold harmless InSite and its officers,
directors, agents, employees and Affiliates from all Liabilities whatsoever in
respect of the breach by P&U of its representations, warranties or default of
any of its obligations contained in this Agreement, or which are based on the
labeling of the Product or marketing and commercialization activities undertaken
to promote the Product, including safety, dosage, manufacturing, processing,
testing, packaging, sale (other than intellectual property claims), warehousing,
distributing, detailing, or promotion.

        SECTION 9.3   INDEMNIFICATION PROCEDURES.

               (a) A party entitled to indemnification hereunder for third party
        claims (the "Indemnitee") that intends to claim indemnification under
        this Article 9 shall: (i) notify the other Party (the "Indemnitor") of
        any Liability with respect to which the Indemnitee intends to claim
        indemnification as soon as practicable after the Indemnitee becomes
        aware of any such Liability; (ii) permit the Indemnitor to assume the
        defense thereof with



                                       18
<PAGE>   23

        counsel mutually satisfactory to the Indemnitee and Indemnitor; and
        (iii) cooperate with the Indemnitor, at the Indemnitor's expense, in the
        defense thereof.

               (b) With respect to any matter for which the Indemnitor may have
        an obligation to indemnify the Indemnitee under this Agreement, the
        Indemnitee shall have the right to participate and be represented (at
        the Indemnitor's expense) by legal counsel of the Indemnitee's choice in
        all proceedings and negotiations, if representation by counsel retained
        by Indemnitor would be inappropriate due to actual or potential
        differing interests between the Indemnitee and any other Party
        represented by such counsel in such proceedings.

               (c) The indemnity agreement in this Article 9 shall not apply to
        amounts paid in settlement of any Liability if such settlement is
        effected without the consent of the Indemnitor, which consent shall not
        be unreasonably withheld.

               (d) Failure of the Indemnitee to deliver notice to the Indemnitor
        within a reasonable time after becoming aware of a Liability shall
        relieve the Indemnitor of any liability to the Indemnitee pursuant to
        this Article 9 in the event, but only to the extent, such delay is
        prejudicial to the Indemnitor's ability to defend such action.

        failure of a Party to comply with or perform any material provision of
        this Agreement, and such failure remains uncured for sixty (60) days
        following written notice of such failure (if such default is cured
        within the cure period, such written notice shall be null and void),
        provided that, if the defaulting Party can establish to the reasonable
        satisfaction of the other Party that it is diligently and actively
        pursuing a cure at the expiration of the cure period, and that the
        default is reasonably capable of being cured, then the cure period shall
        be extended for so long as a cure is being diligently and actively
        pursued, not to exceed 120 days in the aggregate. Notwithstanding the

        ISV-900 Agreement.

               (c) A Party (i) becomes unable to pay its debts as they mature,
        (ii) is the subject of a voluntary or involuntary petition in bankruptcy

        SECTION 11.3 P&U TERMINATION.

               (a) Notwithstanding Section 11.1, P&U shall have the right, in
        its sole discretion, to terminate this Agreement in the event the
        Development Committee, or the Executive Committee, as the case may be,
        determines that the First Milestone described in Schedule 3.3(a) has not
        been met by the * of the Effective Date. P&U shall make such election to
        terminate this Agreement within thirty (30) days after the * of the
        Effective Date by sending written notice to InSite electing such
        termination.

               (b) Notwithstanding Section 11.1, P&U shall have the right to

        gene is not suitable for development as a Product and (ii) the Second
        Milestone has not been achieved by * of the Effective Date. P&U shall
        make such election to terminate this Agreement within sixty (60) days
        after * of the Effective Date by sending written notice to InSite
        electing such termination.

        SECTION 11.4 INSITE TERMINATION. If, at any time after * of the
Effective Date, the Product is not commercialized in a country in the Territory,

        SECTION 11.5  RIGHTS AND OBLIGATIONS UPON TERMINATION.

               (a) Other Penalties. Termination of this Agreement by either

        at law or in equity or otherwise, to seek damages or injunctive relief
        for any breach of this Agreement by the other Party hereto and all
        payment obligations accruing under this Agreement prior to the effective
        date of termination.

               (b) Accrued Rights. Subject to Section 11.3, termination of this

        under or out of this Agreement. The obligations under any other
        provision which expressly or by implication is intended to survive
        expiration or termination shall survive expiration or termination of
        this Agreement.

               (c) Step-in Rights. Upon the termination of this Agreement by
        P&U, pursuant to Section 11.2, InSite shall assign, transfer and convey
        to P&U all of InSite's rights under the ISV-900 Agreements. Upon
        acceptance of such assignment by P&U, P&U shall become responsible for
        all obligations, including fees and royalties, under the ISV-900
        Agreements accruing after the effective time of such assignment. InSite
        shall take all action reasonably requested by P&U to effectuate such
        assignment, including, among other things, the amendment of any ISV-900
        Agreement necessary to permit P&U such step-in rights.

               (d) Reversion Rights. Upon the termination of this Agreement by
        InSite pursuant to Sections 11.2 or 11.4 or by P&U pursuant to Section

        ISV 900 Technology shall revert to InSite on a country by country basis
        in the Territory where InSite or P&U, as the case may be, has terminated
        this Agreement, provided, however, that with respect to (i) any
        termination by InSite under Section 11.4, (ii) any termination by InSite
        under Section 11.2 that occurs after the * of the Effective Date, or
        (iii) any termination by P&U under Section 11.3, P&U shall be entitled
        to * royalty on all net sales of Product to Third Parties by InSite, its
        Affiliates, sublicensees, distributors or other agents in any such
        country or countries in the Territory in which (x) the Product is
        ultimately marketed or commercialized and (z) wherein the manufacture,
        use, processing, importation, distribution, detailing or sale of the
        Product would infringe any filed ISV-900 Patent. InSite's obligation to
        pay P&U any royalty under this Section 11.5(d) shall expire on a country
        by country basis on the expiration of the last to expire of such ISV-900
        Patents or earlier upon the revocation of such Patents or if such
        Patents are held unenforceable or invalid by decision of a court or
        government agency of competent jurisdiction. Notwithstanding anything in
        this Section 11.5(d) to the contrary, in the event that InSite (or any
        other party to an ISV-900 Agreement with patent filing obligations) has
        not filed any ISV-900 Patent in any country in the Territory in which
        this Agreement has been terminated as referenced in (i) through (iii)
        above and in which the Product is being marketed or commercialized, then
        InSite shall be obligated to pay P&U a royalty under this Section
        11.5(d) in the amount of * of net sales of the Product in any such
        country or countries in the Territory, provided that such obligations
        shall expire on the * of the First Commercial Sale of Product in such
        country or countries and, provided further, that upon the filing of an
        ISV-900 Patent in any such country wherein InSite is paying P&U a *
        royalty, then InSite shall pay P&U a * royalty as otherwise provided for
        in this Section 11.5(d). For purposes of this Section 11.5, "net sales"
        shall have the meaning set forth in Section 1.26 except that all
        references to P&U shall be changed to InSite. Nothing in this agreement
        shall entitle P&U to any royalty in the event InSite terminates this
        agreement pursuant to Section 11.2 prior to the * of the Effective Date
        or gives notice of such termination prior thereto, provided that
        termination pursuant to such notice later becomes effective and final
        prior to the * of the Effective Date.

* Indicates that material has been omitted and confidential treatment has
  been requested therefor. All such omitted material has been filed separately

        SECTION 12.1 NON-ARBITRABLE ISSUES. The Parties acknowledge that matters
to be decided by the Development Committee or the Executive Committee shall not

be resolved in accordance with the provisions setting forth the scope of their

        SECTION 12.2 DISPUTES. Subject to Section 12.1, the Parties recognize
that disputes as to certain matters may from time to time arise that relate to
either Party's rights and/or obligations under this Agreement. It is the
objective of the Parties to establish procedures to facilitate the resolution of
such disputes in an expedient manner by mutual cooperation and without resort to
litigation.

        SECTION 12.3 ATTEMPT TO RESOLVE. The Parties agree to take all
reasonable efforts to resolve in an amicable manner any dispute between them

seek to have the issue resolved as otherwise provided herein.

        SECTION 12.4 BINDING ARBITRATION. Except in the event of alleged breach,
default or lack of diligence by a bankrupt or insolvent Party, the Parties agree
that any material dispute that arises from or is related to this Agreement or
the interpretation, application, breach, termination or validity thereof, and
which cannot be amicably resolved by the Parties, shall be resolved by binding
arbitration (except as provided for in Section 12.1 and 12.13) pursuant in this
Article 12 conducted in accordance with the Commercial Arbitration Rules of the
American Arbitration Association (AAA) by three (3) arbitrators.

        SECTION 12.5 WRITTEN NOTICE. If a Party intends to begin an arbitration
to resolve a dispute, such Party shall provide written notice to the other
Party, informing the other Party of such intention and the issues to be
resolved. Within twenty (20) business days after its receipt of such notice, the
other Party may, by written notice to the Party initiating arbitration, add
additional issues to be resolved.

        SECTION 12.6 SELECTION OF ARBITRATORS. Within forty-five (45) days

arbitrator, agree on the appointment of a third arbitrator who will act with
them and be chairperson of the arbitration panel. In the event that either Party
shall fail to appoint an arbitrator within thirty (30) days after the
commencement of the arbitration proceeding, the arbitrator shall be appointed by
the AAA in accordance with the AAA's Rules. In the event of the failure of the
two (2) arbitrators to agree

event the aggregate damages sought by the claimant are stated to be less than $1
million, and the aggregate damages sought by the counterclaimant are stated to
be less than $1 million, and neither side seeks equitable relief, then a single
arbitrator shall be chosen, having the same qualifications and experience
specified above.

        SECTION 12.7 HEARINGS. The arbitrators shall conduct one or more
hearings to allow the Parties to present their positions regarding the dispute.

               (a) The arbitrators shall determine what discovery will be
        permitted, consistent with the goal of limiting the cost and time that
        the Parties must expend for discovery; provided the arbitrators shall
        permit such discovery as they deem necessary to permit an equitable
        resolution of the dispute. The arbitrators shall have sole discretion
        with regard to the admissibility of any evidence.

               (b) At least ten (10) business days prior to a hearing, each
        Party must submit to the arbitrators and serve on the other Party a
        proposed ruling on each issue to be resolved. Such writings shall be
        limited to not more than fifty (50) pages.

               (c) Each Party shall be entitled to no more than eight (8) days
        of hearing to present testimony or documentary evidence. Such time
        limitation shall include any direct, cross or rebuttal testimony, but
        such time limitation shall only be charged against the Party conducting
        such direct, cross or rebuttal testimony. It shall be the responsibility
        of the arbitrators to determine whether the Parties have had the eight
        (8) days to which each is entitled.

                (d) Each Party shall have the right to be represented by
        counsel.

the award or decision shall be rendered by a majority of the members of the
panel provided for herein, with each member having one (1) vote. The arbitrators
shall render a written decision with their resolution of the dispute. The
decision of the arbitrators shall be final and non-appealable and binding on the
Parties.

        SECTION 13.1 RECORD-KEEPING. InSite and P&U shall keep complete and

        SECTION 13.4 FORCE MAJEURE. Neither Party shall lose any rights
hereunder or be liable to the other Party for damages or losses on account of
failure of performance by the defaulting Party if the failure is caused by Force
Majeure or any other similar cause beyond the control of the defaulting Party;
provided, however, that the Party claiming Force Majeure has exerted all
reasonable efforts to avoid such Force Majeure and has given prompt notice to
the other Party of any such Force Majeure. The Party giving such notice shall be
excused from such of its obligations hereunder as it is disabled from performing
for so long as it is disabled; provided, however, that Party commences and

promptly to determine an equitable solution to the effects of such event. Force
Majeure shall not include a Party's failure to perform any obligation to this

bound by all of the obligations of InSite as contained herein.

        SECTION 4.3 INVESTMENT REPRESENTATIONS. In connection with the purchase
and sale of shares under this Agreement, P&U makes the following
representations:

               (a) P&U is acquiring the shares of Common Stock under this
        Agreement for its own account, not as nominee or agent, for investment
        and not with a view to the resale or distribution or public offering
        thereof within the meaning of the Securities Act of 1933, as amended
        (the "Securities Act"). P&U has no present intention of selling,
        granting any participation in, or otherwise distributing the Common
        Stock acquired hereunder and has not entered into any agreement or
        arrangement with any person with respect to such activities.

               (b) P&U understands that (i) the shares of Common Stock to be
        purchased under this Agreement have not been registered under the
        Securities Act by reason of a specific exemption therefrom, that such
        securities are therefore "Restricted Securities" under the Securities
        Act and must be held by P&U, and that P&U must bear the economic risk of
        such investment, until a subsequent disposition thereof is registered
        under the Securities Act or is exempt from such registration; (ii) each
        certificate representing such shares will be endorsed with the following
        legend:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER THE
               SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO
               RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE
               TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND THE
               APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
               EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE
               AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE
               ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN
               COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

        and (iii) the Company will instruct any transfer agent not to register
        or effect the transfer of the shares of Common Stock unless the
        conditions specified in the foregoing legends are satisfied, until such
        time as a transfer is made, pursuant to the terms of this Agreement, and
        in compliance with Rule 144 or pursuant to a registration statement or,
        if the opinion of counsel referred to above is to the further effect
        that such legend is not required in order to establish compliance with
        any provisions of the Securities Act or this Agreement.

               (c) P&U has such knowledge and experience in financial and
        business matters that it is capable of evaluating the merits and risks
        of the investment in the shares of Common Stock purchased hereunder and
        is financially able to bear the risks thereof.

        prescribed by the Securities and Exchange Commission pursuant to the
        Securities Act.

               (e) P&U 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 Common Stock and to obtain additional
        information necessary to verify the accuracy of the information given to
        P&U. P&U has received information that it considers necessary or
        appropriate for deciding whether to purchase the Common Stock.

               (f) P&U is not a party to any agreement or instrument, or subject
        to any charter or other corporate restriction or 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.

with the transactions contemplated by this Agreement.

to transact business and is in good standing in each jurisdiction in which the
failure so to qualify would have a material adverse effect on its business or
properties.

        SECTION 4.6 VALIDITY OF AGREEMENT. No action, suit, proceeding or
investigation is pending or threatened that questions the validity of this
Agreement or any other agreement contemplated hereby or the right of P&U to
enter into such agreements.

        SECTION 4.7 GOVERNMENTAL CONSENTS. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state, local or provincial governmental authority on

        taxes due pursuant to those tax returns or

        any assessment received by it or otherwise required to be paid, except
        taxes being contested in good faith by appropriate proceedings, if
        applicable.

        SECTION 6.2 NEGATIVE COVENANTS OF THE COMPANY. The Company agrees that,
so long as P&U, individually or collectively with its affiliates owns at least
five percent (5%) of the Company's outstanding Common Stock, it shall not do,
without P&U's prior written approval (which approval shall not be unreasonably
withheld), any of the following:

               (a) Amend its Certificate of Incorporation or its by-laws in any
        manner that would materially and adversely affect the ability of the
        Company to consummate the transactions contemplated by this Agreement or
        the ISV-900 Project Agreement.

               (b) Directly or indirectly sell, lease, or otherwise dispose of
        (other than through a license) any of the assets related to the ISV-900
        Project other than in a merger or sale of the entire Company or all or
        substantially all of the assets. Any successor of InSite pursuant to a
        merger or otherwise shall be bound by all of the obligations of InSite
        as contained herein. However, the Company may license its other products
        to third parties, provided that the Company notifies P&U of any such
        license before that license becomes effective.

               (c) Transfer any of the Company's material assets used in its
        business to any person and thereafter directly or indirectly lease back
        the same or similar property.

               (d) Make any significant change in its accounting policies,
        except for any change required by GAAP or otherwise in the opinion of
        the Company's independent public accountants.

        SECTION 6.3   DEMAND REGISTRATION.

               (a) At any time that P&U owns any Common Stock of the Company,
        P&U shall have the right to cause the Company to register such
        Registrable Shares (as defined below) with the Securities and Exchange
        Commission and qualify such shares with such state securities
        commissions as P&U shall reasonably request in order to allow P&U to
        sell such shares, provided that the Company shall not be required to
        qualify such shares in any state where such qualification would require
        the Company to consent to personal jurisdiction in such state (the
        "Demand Registration Right"). P&U shall be entitled to a total of *
        Demand Registration *. As used in Sections 6.4 through 6.9 and 7.2, the
        term "Registrable Shares" shall mean all Common Stock issued to P&U
        pursuant to this Agreement.

               (b) If, any offering pursuant to the P&U Demand Registration
        Right, involves an underwriting and any other person has piggy-back
        registration rights with respect to such registration, and the managing
        underwriter shall impose a limitation on the number of shares which may
        be included in the registration statement because, in its judgment, such
        limitation is necessary to effect an orderly public distribution or
        because in its

* 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
<PAGE>   12

        judgment the inclusion of shares being sold by persons other than P&U
        would adversely affect the offering, then the Company shall not be
        obligated to include in such registration statement any portion of
        shares of any other person or P&U as provided in 6.3(c) below.

               (c) Notwithstanding any other provision of this Section 6.3, if
        the underwriter, in its reasonable judgment, advises the Company in
        writing that marketing factors require a limitation of the number of
        shares to be underwritten, then the Company shall so advise P&U, and any
        other holders of registrable securities which would otherwise be
        underwritten pursuant to such registration statement, and the number of
        shares of registrable securities that may be included in the
        underwriting shall be allocated among all such persons, including P&U,
        first to P&U, and any other persons making such demand together with P&U
        and then to all other persons, and in each case, in proportion (as
        nearly as practicable) to the amount of registrable securities of the
        Company owned by each such person.

               (d) Notwithstanding the foregoing, if the Company shall furnish
        to P&U a certificate signed by the Chief Executive Officer of the
        Company stating that, in the good faith judgment of the Board of
        Directors of the Company, it would be seriously detrimental to the
        Company and its stockholders for such registration statement to be filed
        and it is therefore essential to defer the filing of such registration
        statement, the Company shall have the right to defer taking action with
        respect to such filing for a period of not more than ninety (90) days
        after receipt of the demand of P&U; provided that the Company may not
        utilize this right more than once in any twelve-month period.

        SECTION 6.4   PIGGY-BACK REGISTRATION.

               (a) If the Company shall determine at any time to register for
        its own account or the account of others under the Securities Act any of
        its equity securities, other than on Form S-4 or Form S-8 or their then
        equivalents or otherwise relating to shares of Common Stock to be issued
        in connection with any acquisition of any entity or business or shares
        of Common Stock issuable under stock option or other employee benefit
        plans, it shall send to P&U written notice of such determination and, if
        within five (5) business days after receipt of such notice, P&U shall so
        request in writing, the Company shall use its best efforts to include in
        such registration statement all or any part of the Registrable Shares
        that P&U requests to be registered.

               (b) If, in connection with any offering involving an
        underwriting, the managing underwriter shall impose a limitation of the
        number of shares which may be included in the registration statement
        because, in its judgment, such limitation is necessary to affect an
        orderly public distribution or because in its judgment the inclusion of
        shares being sold by persons other than the Company would adversely
        effect the offering, then the Company shall be obligated to include in
        such registration statement only such limited portion (which may be
        none) of the Registrable Shares with respect to which P&U has requested
        inclusion pursuant hereto as may reasonably be determined by the
        managing underwriter. Any inclusion of Registrable Shares in an
        offering, when the



                                       11
<PAGE>   13

        managing underwriter has so limited the number of shares that may be
        included in such offering, shall be allocated pro rata among the holders
        of similar "piggyback" registration rights granted by the Company
        seeking to include their shares, in proportion to the number of shares
        (whether or not such shares are sought to be included in such offering)
        held by such persons. The Company shall have the right to delay or
        withdraw any registration initiated by it pursuant to Section 6.4
        hereof.

        SECTION 6.5 EFFECTIVENESS. The Company will use its best efforts to
maintain the effectiveness for up to 90 days, (or such shorter period of time as
the underwriters need to complete the distribution of a registered offering or
until the securities are actually sold) of any registration statement pursuant
to which any of the Registrable Shares are being offered, and from time to time
will amend or supplement such registration statement and the prospectus
contained therein to the extent necessary to comply with the Securities Act and
any applicable state securities laws or regulations.

        SECTION 6.6   INDEMNIFICATION.

               (a) In the event that the Company registers any of the
        Registrable Shares under the Securities Act, the Company will indemnify
        and hold harmless P&U and each underwriter of Registrable Shares
        (including their officers, directors, affiliates and partners and
        including any broker or dealer through whom Registrable Shares may be
        sold in such registration) and each person, if any, who controls P&U or
        any such underwriter within the meaning of Section 15 of the Securities
        Act from and against any and all losses, claims, damages, expenses or
        liabilities, joint or several, to which they or any of them become
        subject under the Securities Act, applicable state securities laws or
        under any other statute or at common law or otherwise, as incurred, and,
        except as hereinafter provided, will reimburse P&U, each such
        underwriter and each such controlling person, if any, for any legal or
        other expenses reasonably incurred by them or any of them in connection
        with investigating or defending any actions whether or not resulting in
        any liability, as incurred, insofar as such losses, claims, damages,
        expenses, liabilities or actions arise out of or are based upon any
        untrue statement or alleged untrue statement of a material fact
        contained in the registration statement, in any preliminary or amended
        preliminary prospectus or in the final prospectus (or the registration
        statement or prospectus as from time to time amended or supplemented by
        the Company) or arise out of or are based upon the omission or alleged
        omission to state therein a material fact required to be stated therein
        or necessary in order to make the statements therein not misleading, or
        any violation by the Company of any rule or regulation promulgated under
        the Securities Act or any state securities laws applicable to the
        Company and relating to action or inaction required of the Company in
        connection with such registration, unless (i) such untrue statement or
        alleged untrue statement or omission or alleged omission was made in
        such registration statement, preliminary or amended preliminary
        prospectus or final prospectus in reliance upon and in conformity with
        information furnished in writing to the Company in connection therewith
        by P&U or any such underwriter expressly for use therein, or unless (ii)
        in the case of a sale directly by P&U (including a sale of Registrable
        Shares through any underwriter retained by P&U to engage in a
        distribution



                                       12
<PAGE>   14

        solely on behalf of P&U), such untrue statement or alleged untrue
        statement or omission or alleged omission was contained in a preliminary
        prospectus and corrected in a final or amended prospectus copies of
        which were delivered to P&U or such underwriter on a timely basis, and
        P&U or such underwriter failed to deliver a copy of the final or amended
        prospectus at or prior to the confirmation of the sale of the
        Registrable Shares to the person asserting any such loss, claim, damage
        or liability in any case where such delivery is required by the
        Securities Act; provided, however, that the indemnity agreement
        contained in this subsection 6.6(a) shall not apply to amounts paid in
        settlement of any such loss, claim, damage, expense, liability or action
        if such settlement is effected without the consent of the Company, which
        consent shall not be unreasonably withheld.

               (b) P&U will indemnify and hold harmless the Company, each
        underwriter of Registrable Shares and any other persons selling
        securities in such registration statement (including their officers,
        directors, affiliates and partners and including any broker or dealer
        through whom Registrable Shares may be sold in such registration) and
        each person, if any, who controls the Company, any such underwriter or
        other such person selling securities in such registration statement
        within the meaning of Section 15 of the Securities Act from and against
        any and all losses, claims, damages, expenses or liabilities, joint or
        several, to which they or any of them may become subject, under the
        Securities Act, applicable state securities laws or under any other
        statutes or at common law or otherwise, as incurred, insofar as such
        losses, claims, damages, expenses or liabilities (or actions in the
        respect thereto) arise out of are based upon any untrue statement or
        alleged untrue statement of a material fact contained in the
        registration statement, in any preliminary or amended preliminary
        prospectus or in the final prospectus (or the registration statement or
        prospectus as from time to time amended or supplemented by the Company)
        or arise out of or are based upon the omission or alleged omission to
        state therein a material fact required to be stated therein or necessary
        in order to make the statements therein not misleading, or any violation
        by the Company of any rule or regulation promulgated under the
        Securities Act or any state securities laws applicable to the Company
        and relating to action or inaction required of the Company in connection
        with such registration, in each case to the extent (and only to the
        extent) that such untrue statement, alleged untrue statement, alleged
        omission, omission or violation occurs in reliance upon and in
        conformity with written information furnished by or on behalf of P&U
        expressly for use in connection with such registration; and P&U will
        reimburse, as incurred, the Company, each such underwriter, each such
        other person selling securities in such registration statement and each
        such controlling person, if any, for any legal or other expenses
        reasonably incurred by them or any of them in connection with
        investigating or defending any such loss, claim, damage, liability or
        action, whether or not resulting in any liability; provided, however,
        that the indemnity agreement contained in this subsection 6.6(b) shall
        not apply to amounts paid in settlement of any such loss, claim, damage,
        expense, liability or action if such settlement is effected without the
        consent of P&U, which consent shall not be unreasonably withheld. In any
        event, except in the case of willful misconduct or fraudulent
        misrepresentations, the liability of P&U under the indemnity provisions
        of this Agreement shall be limited to an



                                       13
<PAGE>   15

        amount equal to the gross proceeds received by P&U from the sale of
        shares in any transaction to which such indemnification relates.

               (c) Promptly after receipt by an indemnified person under this
        Section 6.6 of notice of the commencement or threat of any action in
        respect of which indemnity may be sought against the indemnifying party,
        such indemnified person shall notify the indemnifying party in writing
        of the commencement thereof (provided, that failure to so notify the
        indemnifying party shall not relieve the indemnifying party from any
        liability it may have hereunder, except to the extent prejudiced by such
        failure) and, subject to the provisions hereinafter stated, the
        indemnifying party shall be entitled to assume the defense of such
        action (including the employment of counsel) and the payment of expenses
        insofar as such action shall relate to any alleged liability in respect
        of which indemnity may be sought against the indemnifying party.

               (d) An indemnified person under this Section 6.6 shall have the
        right to employ separate counsel in any such action and to participate
        in the defense thereof but the fees and expenses of such counsel
        subsequent to any assumption of the defense by the indemnifying party
        shall not be at the expense of the indemnifying party (but shall be at
        the sole expense of the indemnified person) unless the employment of
        such counsel has been specifically authorized in writing by the
        indemnifying party; provided, however, that, if the defendants in any
        such action include both the indemnified person and the indemnifying
        party and the indemnified person shall have reasonably concluded that
        there may be reasonable defenses available to it which are different
        from or additional to those available to the indemnifying party or if
        the interests of the indemnified person reasonably may be deemed to
        conflict with the interests of the indemnifying party, the indemnified
        person shall have the right to select a separate counsel and to assume
        such legal defenses and otherwise to participate in the defense of such
        action, with the expenses and fees of such separate counsel and other
        expenses related to such participation to be reimbursed by the
        indemnifying party as incurred. At any time, an indemnified person may
        select separate counsel and assume its own legal defense with the
        expenses and fees of such separate counsel and other expenses related to
        such separate counsel to be borne by such indemnified person. An
        indemnifying party shall not be liable to an indemnified person for any
        settlement of any such action effected without the indemnifying party's
        written consent (which consent shall not be unreasonably withheld or
        delayed). An indemnifying party shall not, except with the approval of
        each party being indemnified under this Section 6.6 (which approval
        shall not be unreasonably withheld or delayed), consent to entry of any
        judgment or enter into any settlement which does not include as an
        unconditional term thereof the giving by the claimant or plaintiff to
        the parties being so indemnified of a release from all liability in
        respect to such claim or litigation.

               (e) In order to provide for just and equitable contribution to
       joint liability under the Securities Act in any case in which an
       indemnified person makes a claim for indemnification pursuant to this
       Section 6.6 but indemnification is unavailable to or insufficient to hold
       harmless an indemnified person, or it is judicially determined (by the



                                       14
<PAGE>   16

       entry of a final judgment or decree by a court of competent jurisdiction
       and the expiration of time to appeal or the denial of the last right of
       appeal) that such indemnification may not be enforced in such case
       notwithstanding the fact that this Section 6.6 provides for
       indemnification in such case, then the indemnifying party and the
       indemnified person will contribute to the aggregate losses, claims,
       damages or liabilities to which they may be subject (after contribution
       from others) in such proportion as is appropriate to reflect the relative
       fault of the indemnifying party on the one hand and of the indemnified
       person on the other hand in connection with the statements or omissions
       which resulted in such losses, claims, damages or liabilities, as well as
       any other relevant equitable considerations. The relative fault of the
       indemnifying party on the one hand and of indemnified person on the other
       hand shall be determined by reference to, among other things, whether the
       untrue or alleged untrue statement of a material fact or omission or
       alleged omission to state a material fact relates to information supplied
       by the Company on the one hand or by P&U on the other hand, and each
       party's relative intent, knowledge, access to information and opportunity
       to correct or prevent such statement or omission; provided, however,
       that, in any such case, (A) except in the case of willful misconduct or
       fraudulent misrepresentations, P&U will not be required to contribute any
       amount in excess of the public offering price of all Registrable Shares
       offered by it pursuant to such registration statement; and (B) no person
       or entity guilty of fraudulent misrepresentation (within the meaning of
       Section 11(f) of the Securities Act) will be entitled to contribution
       from any person or entity who was not guilty of such fraudulent
       misrepresentation.

        SECTION 6.7 FURTHER OBLIGATIONS OF THE COMPANY. Whenever under the
preceding Sections of this Article 6, the Company is required to register
Registrable Shares, the Company agrees that it shall also do the following:

               (a) Furnish to P&U such copies of each preliminary and final
        prospectus and such other documents as P&U may reasonable request to
        facilitate the public offerings of the Registrable Shares;

               (b) Use its best efforts to register or qualify the Registrable
        Shares covered by the registration statement under the applicable
        securities or "blue sky" laws of such jurisdictions as P&U may
        reasonably request;

               (c) Permit P&U or its counsel or other representatives to inspect
        and copy such corporate documents and records as may reasonably be
        requested by them, after reasonable advance notice, during normal
        business hours and without undue interference with the operation of the
        Company's business;

               (d) Furnish to P&U a copy of all documents filed with and all
        correspondence from or to the Securities and Exchange Commission in
        connection with any such offering of securities;



                                       15
<PAGE>   17

               (e) Otherwise use its best efforts to comply with all applicable
        rules and regulations of the Securities and Exchange Commission, and (to
        the extent required) make available to its security holders, as soon as
        reasonably practicable, an earning statement covering the period of at
        least twelve months, but not more than eighteen months, beginning with
        the first month after the effective date of the registration statement
        covering a public offering, which earning statement shall satisfy the
        provisions of Section 11(a) of the Securities Act and Rule 158
        thereunder.

        SECTION 6.8 EXPENSES. In the case of each registration effected under
Sections 6.3, 6.4 and 6.7, * shall bear * reasonable costs and expenses of each
such registration *, including, but not limited to, * printing, legal and
accounting fees and expenses, Securities and Exchange Commission and NASD or
AMEX (as applicable) filing fees and "blue sky" fees and expenses; provided,
however, that * shall have no obligation to pay or otherwise bear any portion of
*, or the fees and expenses of counsel for P&U in connection with the
registration of the Registrable Shares.

        SECTION 6.9 TERMINATION OF REGISTRATION RIGHTS. No holder of Registrable
Shares shall be entitled to exercise any right provided for in, and the Company
shall have no obligation pursuant to, Sections 6.3, 6.4, 6.5 or 6.7 hereof after
such time as all Registrable Shares held by a holder may be sold pursuant to
Rule 144 promulgated under the Securities Act during a given ninety-day period;
provided, however, if the Company fails to comply with SEC Rule 144(c)(1), the
Company's obligations pursuant to Section 6.3, 6.4, 6.5 and 6.7 hereof shall be
reinstated for so long as such failure to comply shall continue.

                                COVENANTS OF P&U

offer, merger, proxy contest or otherwise; (b) the commencement of a tender
offer by any person or entity to acquire beneficial ownership of 9.99% or more
of the Company's outstanding voting equity securities; or (c) the solicitation
of proxies by any party other than the Company to which Rule 14(a) of the rules
and regulations under the Securities and Exchange Act of 1934, as amended,
applies and is intended to effect a change in the majority of members of the
Company's Board of Directors.

        SECTION 7.2 REGISTRATION. Whenever under the preceding Sections of
Article 6, P&U is registering Registrable Shares pursuant to any registration
statement, (i) P&U agrees to timely provide to the Company, at its request, such
information and materials as it may reasonably request in order to effect the
registration of such Registrable Shares and (ii) if the offering is
underwritten, the Company and P&U agrees to execute an underwriting agreement
containing customary terms and conditions.

        SECTION 7.3 VOTING AGREEMENT. P&U 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 of the
Company's equity securities 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 P&U
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 P&U.

        SECTION 7.4 LIMITATION ON SECURITIES ISSUED PURSUANT TO THIS AGREEMENT.
Unless permitted by the applicable rules and regulations of the American Stock
Exchange, in no event shall the total number of shares of Common Stock issued
pursuant to this Agreement exceed the maximum number of shares of Common Stock
that the Company can so issue pursuant to Rule 713(a) of the American Stock
Exchange (or any successor rule or comparable rule of an applicable exchange or
automated quotation system) which, as of the date of this Agreement shall be
19.99% of shares outstanding on the date of this Agreement.

        SECTION 8.1 GOVERNING LAW. This Agreement shall be governed by and
interpreted in accordance with the substantive laws of the State of New York and
the United States of America, without regard to choice of law rules thereof.

this Agreement or any aspect of this Agreement shall be made subject to and in
accordance with the terms of the ISV-900 Project Agreement.

        SECTION 8.3 ASSIGNMENT. The rights and obligations under this Agreement
may not be assigned by either the Company or P&U without the prior written
consent of the other party; provided, however, that the Company may, without the
prior consent of P&U, assign the rights and obligations under this Agreement to
the acquiring company or any of its affiliates in connection with a merger,
combination or sale of all or substantially all of the assets of the Company.

        SECTION 8.4 SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions of this Agreement shall inure to the benefit of,
and be binding upon, the successors, and permitted assigns of the Company and
P&U.

        SECTION 8.5 ENTIRE AGREEMENT. This Agreement and the ISV-900 Project
Agreement (and all of their exhibits and appendices (collectively, the
"Agreements")) set forth all of the covenants, promises, agreements, warranties,
representations, conditions, and understandings between the Company and P&U and
supersede and terminate all prior agreements and understandings between these
parties with respect to the subject matter hereof and thereof. There are no
covenants, promises, agreements, warranties, representations, conditions or
understandings, either oral or written, between the Company and P&U other than
as set forth in the Agreement, the ISV-900 Project Agreement (and all of their
exhibits and appendices). The Agreements are intended to define the full extent
of the legally enforceable undertakings of the Company and P&U and no promise or
representation, whether written or oral, which is not set forth explicitly
herein or therein is intended by either party to be legally binding. The Company
and P&U acknowledges that, in deciding to enter into this Agreement and to
consummate the transactions contemplated under this Agreement, neither has
relied upon any statement or representation, written or oral, other than those
explicitly set forth in this Agreement.

        SECTION 8.6 SEVERABILITY. Whenever possible, each provision of the
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of the Agreement is held to be prohibited
by or invalid under applicable law, such provision will be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of the Agreement. In the event of such invalidity, the parties shall seek to
agree on an alternative enforceable provision that preserves the original
purpose of this Agreement.

        SECTION 8.7 AMENDMENT AND WAIVER. Except as otherwise provided herein,
any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance, either
retroactively or prospectively, and either for a specified period of time or
indefinitely), with the written consent of the Company and P&U. No amendment to
this Agreement shall be binding upon the parties unless reduced to writing and
signed by the respective authorized officers of the parties. Any amendment or
waiver effected in accordance with this Section shall be binding upon any holder
of any securities purchased under this Agreement (including securities into
which such securities have been converted), each future holder of all such
securities, and the Company.

Pharmacia & Upjohn AB
c/o Pharmacia & Upjohn Company
100 Route 206 North
Peapack, New Jersey 07977

               Re: InSite Vision Incorporated

Ladies and Gentlemen:

               We have acted as counsel to InSite Vision Incorporated, a
Delaware corporation (the "Company") in connection with the transactions set
forth and contemplated by the Stock Purchase Agreement to be entered into
contemporaneously herewith by and between Pharmacia & Upjohn AB and the Company
(the "Stock Purchase Agreement"). This opinion is furnished to you pursuant to
Section 5.1(d) of the Stock Purchase Agreement.

               In rendering the opinions expressed below, we have examined and
are familiar with originals or copies of the Company's Certificate of
Incorporation, and all amendments thereto, as certified by the Delaware
Secretary of State (the "Certificate"), the Company's Bylaws, a Certificate of
Good Standing for the Company issued by the Delaware Secretary of State and such
other agreements, instruments and documents as we have deemed necessary as a
basis for such opinions.

               In rendering the opinions set forth herein, we have assumed (i)
the genuineness of all signatures on all documents submitted to us, (ii) the
capacity and competence of each natural person who executed any of these
documents, (iii) the authenticity of all documents submitted to us as originals
and of the originals of all documents submitted to us as copies, (iv) the
conformity with the original documents of all documents submitted to us as
copies and (v) the filing by the Company of all legal forms and documents
required to be filed by the Company, and such filings being made in conformity
with law.

               Based on the foregoing and subject to the qualifications and
limitations set forth herein, we are of the opinion that:

               1. InSite Vision Incorporated is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware
and is qualified and in good standing as a foreign corporation in each
jurisdiction in which such qualification is required or necessary.

               2. The authorized capital of the Company is as set forth in the
Certificate as certified by the Delaware Secretary of State on the date hereof.


                                       D-1
<PAGE>   26



               3. The Company has full corporate power and authority to execute
and deliver the Stock Purchase Agreement and all agreements related thereto, and
to carry out the transactions contemplated thereby.

               4. The Stock Purchase Agreement and all agreements related
thereto, have been duly authorized and approved by such directors and officers
that are legally required therefor, have been duly executed and delivered by the
Company.

               5. The execution and delivery of the Stock Purchase Agreement and
all other agreements or instruments entered into or delivered in connection with
the transactions contemplated thereby and the performance by the Company of
their terms (i) do not conflict with or result in a violation of the Company's
Certificate or Bylaws or any judgment, order or decree of any court or agency to
which the Company or its assets is subject and (ii) do not conflict with and
will not, with or without notice or lapse of time, constitute a material breach
or default of or result in any lien under any material contract, undertaking,
indenture or other agreement or instrument by which the Company is bound or to
which it is a party.

               6. No notice, consent, authorization, approval or order is
required to be given or obtained by the Company of any court or governmental
agency or body for the consummation by the Company of the transactions
contemplated by the Stock Purchase Agreement or any of the other agreements
related thereto.

               7. There is no suit, action, or legal, administrative,
arbitration, or other proceeding pending, or threatened against the Company
pertaining to the transactions contemplated by the Stock Purchase Agreement.

               The opinions expressed herein are solely for benefit of, and may
be relied upon by, the addressee hereof. The opinions may not be relied upon for
any other purpose or relied upon by any other person, firm or entity for any
purpose. The opinions expressed herein are as of the date hereof.

                                Very truly yours,

                  determination, deem applicable thereto. In the event that such
                  a court determines that the Lender has charged or received
                  interest hereunder or under the other Credit Documents in

                                       date; and

                  (iv)     upon any distribution of shares to Lender pursuant to
                           this Section, Lender shall be deemed to have repeated

                  date except to the extent such representations and warranties
                  are made as of a specific date, in which event they shall be
                  true and correct as of such date, and (2) there exists no
                  Default or Event of Default as of such date, nor would any
                  Default or Event of Default result from the making of the
                  Credit Loan requested by the Borrower;

         (b)      The Borrower shall have signed and sent to the Lender, if the
                  Lender so requests, a request for advance, setting forth in
                  writing the amount of the Credit Loan requested and the other
                  information required pursuant to Section 3.1 hereof; provided,
                  however, that the foregoing condition precedent shall not
                  prevent the Lender, if it so elects in its sole discretion,
                  from making a Credit Loan pursuant to the Borrower's
                  non-written request therefor;

                  be, as each such Committee is defined in the ISV-900 Project
                  Agreement.

         The Borrower agrees that the making of a request by the Borrower for a
         Credit Loan, whether in writing, by telephone or otherwise, shall
         constitute a certification by the Borrower that all representations and
         warranties of the Borrower in the Credit Documents are true as of the
         date thereof except to the extent such representations and warranties
         are made as of a specific date, in which event they shall be true and
         correct as of such date and that all required conditions to the making
         of the Credit Loan have been met.

The Borrower hereby represents, warrants to the Lender as follows on the date
hereof and on each date a Credit Loan is made:

         (a)      Organization and Existence. The Borrower (1) is a corporation
                  duly incorporated, validly existing and in good standing under
                  the laws of the state of its incorporation, (2) is in good
                  standing in all other jurisdictions in which it is required to
                  be qualified to do business as a foreign corporation, except
                  where failure to be so qualified would not have a material
                  adverse effect, and (3) has obtained all licenses and permits
                  and has filed all registrations necessary to the operation of
                  its business (except where the failure to so qualify or to
                  obtain such licenses or permits would not materially and
                  adversely affect the business, financial condition or
                  operations of the Borrower, a "Material Adverse Effect").



                                       10

         (b)      Authorization by the Borrower. The execution, delivery and

                  authorized by all necessary corporate action, (3) do not
                  contravene the Borrower's articles or certificate of
                  incorporation or by-laws, or any material law or contractual
                  restriction binding on or affecting the Borrower or its
                  properties, and (4) do not result in or require the creation
                  of any Lien upon any of Borrower real or personal property.

         (c)      Approval of Governmental Bodies. Based in part upon the
                  representations of the Lender pursuant to Section 2.4, no
                  authorization or approval or other action by, and no notice to
                  or filing with, any governmental authority or regulatory body
                  is required for the due execution, delivery and performance by
                  the Borrower of the Credit Documents or the exercise by the
                  Lender of its rights thereunder.

         (d)      Enforceability of Obligations. The Credit Documents are the
                  legal, valid and binding obligations of the Borrower
                  enforceable against the Borrower in accordance with their
                  respective terms, except as the enforceability thereof may be
                  limited by bankruptcy, insolvency, reorganization, moratorium,
                  or similar laws affecting the enforceability of creditors'
                  rights generally and subject to the discretion of courts in
                  applying equitable remedies.

         (e)      Financial Statements. All financial statements of the Borrower
                  which have been furnished to the Lender fairly present the
                  financial condition of the Borrower, as of the dates reflected
                  on the financial statements, and fairly present the results of
                  its operations for the period covered thereby, all in
                  accordance with GAAP, except for the omission of footnotes in
                  interim financial statements and subject to normal year-end
                  adjustments.

         (f)      Litigation. There is no pending or to the knowledge of
                  Borrower threatened action or proceeding affecting the
                  Borrower or its properties before any court, governmental
                  agency or arbitrator which, if determined adversely to the
                  Borrower, could reasonably be expected to result in a Material
                  Adverse Effect.

         (g)      Existing Debt. The Borrower has no Debt other than Permitted
                  Debt and Debt reflected on its most recent financial
                  statements submitted to the Lender.

                  local and other tax returns and has paid, or made adequate
                  provision for the payment of, any taxes due pursuant thereto
                  or pursuant to any assessment received by the Borrower except
                  such taxes, if any, as are being contested in good faith and
                  as to which adequate reserves have been provided.

         (i)      Hazardous Materials. The Borrower has complied in all material
                  respects with all Environmental Laws and all of its
                  facilities, leaseholds, assets and other property comply in
                  all material respects with all Environmental Laws. To the
                  Borrower's knowledge, there are no outstanding or threatened
                  citations, notices or orders of



                                       11
<PAGE>   15

                  non-compliance issued to the Borrower or relating to its
                  facilities, leaseholds, assets or other property. The Borrower
                  has been issued all material licenses, certificates, permits
                  or other authorizations required under any Environmental Law
                  or by any federal, state or local governmental or
                  quasi-governmental entity.

         (j)      Title to Property. The Borrower has good and marketable title
                  to all material assets and other property owned by it, and
                  reflected in the latest available publicly filed financial
                  statements of the Borrower.

         (k)      Insolvency. After the execution and delivery of the Credit
                  Documents and the disbursement of the initial Credit Loan
                  hereunder, the Borrower will not be insolvent within the
                  meaning of the United States Bankruptcy Code or unable to pay

                  of the Borrower's business and upon fair and reasonable terms
                  substantially as favorable to the Borrower as those which

                  a non-Affiliate.

         (g)      Distributions. The Borrower shall not pay any dividends on or

                  Borrower; or

         (e)      Any material representation or warranty made or furnished by
                  the Borrower in connection with this Agreement, the other

                  than Debt due the Lender) or any material Debt for trade
                  payables or perform or observe any other obligation or term in

                  (except, in the case of a petition filed against the Borrower,
                  if such proceeding is dismissed within 60 days after the
                  petition is filed); or the Borrower makes any offer of

                  money in excess of $250,000 in the aggregate is rendered
                  against the Borrower which judgment remains unsatisfied,
                  unvacated or unstayed pending appeal for 60 days or more after
                  entry thereof; or

         SECTION 6.2 Obligation to Lend; Acceleration. Upon or after the
occurrence and during the continuation of any Event of Default (after taking
into account any applicable cure periods), the Lender may declare the obligation
of the Lender to make Credit Loans or to otherwise extend credit hereunder to be
terminated, whereupon the same shall forthwith terminate. Upon or after the
occurrence and during the continuation of any Event of Default, the Lender may
declare the Credit Note, all interest thereon, and all other Obligations to be
forthwith due and payable, whereupon the Credit Note, all such interest thereon
and all such other Obligations shall become and be forthwith due and payable,
without presentment, protest or further notice or demand of any kind, all of
which are hereby waived by the Borrower.

         SECTION 6.3 Right of Set-off. Upon the expiration of any cure periods

such notice being hereby waived by the Borrower), to set off any indebtedness or
other obligations owing by the Lender to or for the credit or the account of the
Borrower against any and all of the Obligations irrespective of whether or not
the Lender shall have made any demand under this Agreement or the other Credit
Documents and although such Obligations may be unmatured. The rights of the
Lender under this Section are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which the Lender may
have. The Lender agrees to promptly notify the Borrower of any such set-off.

         SECTION 7.2 Indemnity. The Borrower indemnifies, and agrees to
indemnify, the Lender and its shareholders, directors, officers, employees and
agents and hold the Lender and such other indemnitees harmless from and against
any liability, loss, expense, damage, suit, action or proceeding on or after the
Initial Loan Date suffered or incurred by the Lender or such other indemnitees
as the result of such Lender's Credit Loans hereunder and the Borrower's failure
to observe, perform or discharge any of the Borrower's duties under any of the
Credit Documents or any misrepresentation made by or on behalf of the Borrower
under any of the Credit Documents. Without limiting the generality of the
foregoing, this indemnity shall extend to any claims asserted against the Lender
or such other indemnitees by any Person under any Environmental Laws or similar
laws by reason of the Borrower's or any other Person's failure to comply with
laws applicable to Hazardous Substances. All indemnities given by the Borrower
to the Lender under the Credit Documents, including, without limitation, the
indemnities set forth in this Section, shall survive the repayment of the Credit
Loans and the termination of this Agreement. Notwithstanding anything herein to
the contrary, in no event shall Borrower be required to indemnify Lender or any
other indemnity in respect of (a) any taxes (except to the extent set forth in
Section 7.5) or (b) any damage, loss, liability, expense or cost resulting from
the gross negligence or willful default of the Lender or any other indemnitee.

         SECTION 7.3 Entire Agreement; Modification of Agreement. This Agreement
and the other Credit Documents, together with all other instruments, agreements
and certificates incorporated herein by reference or executed by the parties in
connection herewith and therewith or with reference thereto, embody the entire
agreement between the parties hereto and thereto with respect to the subject
matter hereof and thereof and supersede all prior agreements, understandings and
inducements, whether express or implied, oral or written. This Agreement may not
be modified, altered or amended, except by an agreement in writing signed by the
Borrower and the Lender.

         SECTION 7.4 Assignment/Sale of Interest. The Borrower may not sell,
assign or transfer any interest in this Agreement or any of the other Credit
Documents, or any portion thereof, including, without limitation, the Borrower's
rights, title, interests, remedies, powers, and duties hereunder or thereunder.
The Lender may, with the prior written consent of the Borrower not to be
unreasonably withheld (provided that Borrower may refuse to consent to
assignment to a competitor of Borrower in its sole discretion), grant
participations, sell, assign, transfer or otherwise dispose, at any time or
times on or after the Initial Loan Date, of this



                                       17
<PAGE>   21

Agreement and any of the other Credit Documents, or of any portion hereof or
thereof, including, without limitation, the Lender's rights, title, interests,
remedies, powers and duties hereunder or thereunder.

         SECTION 7.5 Reimbursement of Expenses. If, upon or after and during the
continuation of any Event of Default, the Lender employs counsel for advice or
other representation, in connection with any attempt to enforce any rights of
the Lender against the Borrower or any other Person which may be obligated to
the Lender by virtue of this Agreement or any of the other Credit Documents,
irrespective of whether litigation is commenced in pursuance of such rights;
then, in any such event, all reasonable costs and expenses of such counsel shall
be payable, on demand, by the Borrower to the Lender, and shall be additional
Obligations hereunder. Additionally, if any taxes (excluding taxes imposed upon
or measured by the income of the Lender and any foreign taxes imposed on Lender
as a result of (i) entry of this Agreement, (ii) maintenance of any Credit Loans
or (iii) receipt of any payment pursuant hereto) shall be payable on account of
the execution or delivery of this Agreement or the other Credit Documents, or
the execution, delivery, issuance or recording of any of the Credit Documents,
or the creation of any of the Obligations hereunder, by reason of any federal,
state or local statute or other law existing on or after the Initial Loan Date,
the Borrower will pay all such taxes, including, but not limited to, any
interest and penalties thereon, and will indemnify and hold the Lender harmless
from and against liability in connection therewith.

         SECTION 7.6 Indulgences Not Waivers. The Lender's failure, at any time
or times on or after the Effective Date, to require strict performance by the
Borrower of any provision of this Agreement or the other Credit Documents shall
not waive, affect or diminish any right of the Lender thereafter to demand
strict compliance and performance therewith. Any suspension or waiver by the
Lender of a Default or an Event of Default by the Borrower under this Agreement
or any of the other Credit Documents shall not suspend, waive or affect any
other Default or Event of Default by the Borrower under this Agreement or any of
the other Credit Documents, whether the same is prior or subsequent thereto and
whether of the same or of a different type. None of the undertakings,
agreements, warranties, covenants and representations of the Borrower contained
in this Agreement or any of the other Credit Documents and no Default or Event
of Default by the Borrower under this Agreement or any of the other Credit
Documents shall be deemed to have been suspended or waived by the Lender, unless
such suspension or waiver is by an instrument in writing specifying such
suspension or waiver and is signed by a duly authorized representative of the
Lender and directed to the Borrower.

         SECTION 7.7 Severability. Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

         SECTION 7.8 Successors and Assigns. This Agreement and the other Credit
Documents, shall be binding upon and inure to the benefit of the successors and
assigns of the Borrower and the Lender. This provision, however, shall not be
deemed to modify Section 7.4 hereof.



                                       18
<PAGE>   22

         SECTION 7.9 General Waivers by the Borrower. Except as otherwise
expressly provided for in this Agreement, the Borrower waives: (a) presentment,
protest, demand for payment, notice of dishonor, demand and protest and notice
of presentment, default, notice of nonpayment; (b) any and all other notices,
demands and consents in connection with the delivery, acceptance, performance,
default or enforcement of this Agreement or any of the other Credit Documents
and/or any of the Lender's rights thereunder.

         SECTION 7.10 Incorporation by Reference. All of the terms of the other
Credit Documents are incorporated in and made part of this Agreement by
reference; provided, however, that to the extent of any inconsistency between
this Agreement and such other Credit Documents, this Agreement shall prevail and
govern.

         SECTION 7.11 Execution in Counterparts; Facsimile Signatures. This
Agreement and the other Credit Documents may be executed in any number of
counterparts and by different parties thereto, each of which when so executed
and delivered shall be deemed to be an original and all of which counterparts
taken together shall constitute but one and the same instrument. A signature of
a party to any of the Credit Documents sent by facsimile or other electronic
transmission shall be deemed to constitute an original and fully effective
signature of such party.

         SECTION 7.12 Governing Law; Consent to Forum. This Agreement shall be
governed by the laws of the State of New York without giving effect to any
choice of law rules thereof. As part of the consideration for new value this day
received, the Borrower hereby consents to the jurisdiction of any state court
located within New York or federal court in New York, and waives personal
service of any and all process upon it and consents that all such service of
process be made by certified or registered mail directed to the borrower at the
address stated in Section 7.1 hereof and service so made shall be deemed to be
completed upon actual receipt thereof. The Borrower waives any objection to
jurisdiction and venue of any action instituted against it as provided herein
and agrees not to assert any defense based on lack of jurisdiction or venue. The
Borrower further agrees not to assert against the Lender (except by way of a
defense or counterclaim in a proceeding initiated by the Lender) any claim or
other assertion of liability with respect to the Credit Documents, the Lender's
conduct or otherwise in any jurisdiction other than the foregoing jurisdictions.

         SECTION 7.13 Waiver of Jury Trial. To the fullest extent permitted by
law, and as separately bargained-for consideration, the parties hereby waive any
right to trial by jury in any action, suit, proceeding or counterclaim of any
kind arising out of or otherwise relating to any of the Credit Documents.

         SECTION 7.14 Accounting Terms. All accounting terms not specifically
defined herein shall be construed in accordance with GAAP.

         SECTION 7.15 Construction/Headings. This Agreement shall be construed
without regard to any presumption or rule requiring construction against the
party causing such instrument or any portion thereof to be drafted. The Section
and other headings in this Agreement and the index at the beginning of this
Agreement are for convenience of reference
