                            STOCK PURCHASE AGREEMENT

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

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

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

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

         1. Purchase and Sale of Shares.

            1.1 Sale and Issuance of Shares.

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

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

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

         2. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Investor that, except as set forth on a Schedule

             2.2 Authorization. All corporate action on the part of the Company,
its officers, directors, and stockholders necessary for the authorization,

                                       2.
   3

and will be free of restrictions on transfer other than restrictions on transfer

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

foregoing. The foregoing includes, without limitation, actions pending or

Incorporation or Bylaws or of any instrument, judgment, order, writ, decree or

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


                                       3.
   4
impairment, forfeiture, or nonrenewal of any material permit, license,
authorization, or approval applicable to the Company, its business or operations

under which they were made, not misleading.

             2.8 Disclosure. This Agreement and the Schedules and Exhibits
hereto do not contain any untrue statement of material fact or omit to state a
material fact necessary to make the statements mad herein or therein not
misleading in light of the circumstances under which they were made.

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

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

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

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


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

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

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

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

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

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

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

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

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

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

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

         5. Conditions of Investor's Obligations at First Closing and Second

purchased at each of the First Closing and Second Closing, as the case may be,

         7. Covenants of the Investor.

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

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

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

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

         8. Covenants of the Company.

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

         8.2 Registration Rights.

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

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

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

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

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


                                      10.
   11
             8.3 * * * [* 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.]

         9. Miscellaneous.

             9.1 Survival of Warranties. The warranties, representations and
covenants of the Company and the Investor contained in or made pursuant to this
Agreement shall survive the execution and delivery of this Agreement, the First
Closing and the Second Closing and shall in no way be affected by any
investigation of the subject matter thereof made by or on behalf of the Investor
