 This SUBSCRIPTION AGREEMENT (this “Agreement”) made as of the date set forth on the signature page hereof between INSITE VISION
INCORPORATED, a Delaware corporation having a place of business at 965 Atlantic Avenue, Alameda, California 94501 (the “Company”) and the undersigned (each, a “Subscriber” and collectively, the
“Subscribers”). 
  
 W I T N E S S E T H:

  
 WHEREAS, the Company desires to sell Units (as defined below)
to persons who qualify as “accredited investors” as defined in Rule 501 of Regulation D promulgated under the Securities Act of 1933 (the “Securities Act”); and 
  
 WHEREAS, the Subscribers desire to purchase that number of Units set forth on
the signature page hereof on the terms and conditions hereinafter set forth; 
  
 NOW, THEREFORE, in consideration of the promises and the mutual representations and covenants hereinafter set forth, the parties hereto do hereby agree as follows: 
  

	I.	SUBSCRIPTION FOR UNITS 

  
 1.1 Amount of the Offering. The Company will offer to sell to persons who qualify as “accredited investors” as defined in Rule 501 of
Regulation D promulgated under the Securities Act up to an aggregate of 1,500 Units (the “Maximum Offering”), subject to the Company’s right, in its sole discretion, to sell up to an additional aggregate of 300 Units (the
“Over-allotment”). Together, the Maximum Offering and the Over-allotment shall be referred to as the “Offering”. 
  
 (a) Each “Unit” shall consist of: 
  
 (i) a number of shares of common stock of the Company, par value $0.01 per share (the “Common Stock”), determined by
dividing $10,000 (the “Unit Price”) by the average per share closing price of the Common Stock as reported on the American Stock Exchange (“AMEX”) for the five trading days immediately preceding the Initial Closing
(as defined below), but in no case exceeding $0.50 per share (the “Per Share Price”); 
  
 (ii) Class A redeemable warrants (the “Class A Warrants”) to purchase a number of shares of Common Stock equal to 25% of
the Common Stock included in such Unit with an exercise price equal to $0.75 per share; and 

 (iii) Class B redeemable warrants (the “Class B Warrants”) to purchase a
number of shares of Common Stock equal to 25% of the Common Stock included in such Unit with an exercise price equal to $0.75 per share. 
  
 (b) The terms of the Class A Warrants and Class B Warrants (collectively, the “Warrants”) shall be identical with the exception of their
respective redemption prices. In the event that the average closing price of the Common Stock on AMEX for any 20 consecutive trading days is at least $1.50 (subject to proportionate adjustment for stock splits, reverse stock splits and similar
events with respect to the Common Stock occurring after the date hereof) (the “Class A Redemption Price”), the Company shall be entitled to redeem the outstanding Class A Warrants, or any portion of them, at a per warrant share
redemption price of $0.75 (subject to proportionate adjustment for stock splits, reverse stock splits and similar events with respect to the Common Stock occurring after the date hereof) by giving 30 days written notice to the holder. In the event
that the average closing price of the Common Stock on AMEX for any 20 consecutive trading days is at least $2.50 (subject to proportionate adjustment for stock splits, reverse stock splits and similar events with respect to the Common Stock
occurring after the date hereof) (the “Class B Redemption Price”), the Company shall be entitled to redeem the outstanding Class B Warrants, or any portion of them, at a per warrant share redemption price of $1.75 (subject to
proportionate adjustment for stock splits, reverse stock splits and similar events occurring with respect to the Common Stock after the date hereof) by giving 30 days written notice to the holder. The Warrants shall be in substantially the form
attached as exhibits to the Memorandum (as defined herein).  
  
 1.2 Initial Closing. Upon receipt of binding subscription agreements for up to the Maximum Offering in the aggregate plus the Over-allotment, if applicable (the “Subscriptions”), and subject to the other terms and
conditions of this Agreement, at a time to be agreed upon by the Company and Paramount Capital, Inc. (the “Placement Agent”) and of which the Subscribers will be notified by the Placement Agent by facsimile transmittal or otherwise,
the Company will sell to the Subscribers and the Subscribers will purchase from the Company, on a pro-rata basis, that portion of the Common Stock and Warrants included in the Units subscribed for by Subscribers under the terms of the Offering,
equal to a number of Securities (as defined herein), assuming full exercise of the Warrants, that the Company is able to sell upon issuance of 19.9% of the Company’s outstanding shares of Common Stock immediately prior to such issuance (the
“Initial Closing” and such date the “Initial Closing Date”), and the Subscribers will remit to the Escrow Agent prior to the Initial Closing the applicable pro-rata portion of the Aggregate Purchase Price for the
Initial Closing (the “Initial Closing Amount”) for release to the Company at the Initial Closing. In no event shall the Company sell an amount of Securities (assuming full exercise of the Warrants) at the Initial Closing that would
exceed 19.9% of the Company’s outstanding shares of Common Stock immediately prior to such issuance. The Placement Agent will notify each Subscriber, after consultation with the Company, as to such Subscriber’s portion of the Initial
Closing Amount (each an “Initial Subscriber Amount”) by providing such Subscriber with a notice substantially similar to that attached hereto as Exhibit A. The “Aggregate Purchase Price” shall mean the
product of the amount of Units sold to Subscribers and the Unit Price and shall equal the Initial Closing Amount (as defined below) plus the Final Closing Amount (as defined below). Upon compliance with all conditions to the Initial 
  

 2 

 Closing, the Placement Agent, with notice to the Company, shall authorize the Escrow Agent to release the proceeds of the
Initial Closing to the Company, less fees and expenses due to the Placement Agent. Interest, if any, that has accrued with respect to the Initial Closing Amount while in escrow shall also be distributed to the Company at the Initial Closing and
Subscribers will have no right to such interest. 
  
 1.3 Final
Closing. Within five (5) business days after receipt of written notice from the Company that it has obtained stockholder approval meeting the requirements of AMEX (the “Stockholder Approval”) to: (a) issue to the Subscribers the
balance of the Common Stock and Warrants included in the Units (including any shares of Common Stock issuable upon exercise thereof) subscribed for by the Subscribers and not issued at the Initial Closing, (b) issue to the Placement Agent the
warrant pursuant to that certain placement agent agreement by and between the Company and the Placement Agent (the “Placement Warrant”) (including any shares of Common Stock issuable upon exercise thereof), and (c) amend the
Company’s Certificate of Incorporation to increase the number of authorized shares of Common Stock in an amount sufficient to issue the balance of the Common Stock and Warrants included in the Units (including any shares of Common Stock
issuable upon exercise thereof) and the Placement Warrant (including any shares of Common Stock issuable upon exercise thereof), each Subscriber is required, and hereby agrees to fulfill the balance of its Subscription at the Final Closing by
forwarding additional funds to the Escrow Agent prior to the Final Closing equal to, on a pro-rata basis, the Aggregate Offering Amount minus the Initial Closing Amount (the “Final Closing Amount”). Upon compliance with all
conditions to the Final Closing, the Placement Agent, with notice to the Company, shall authorize the Escrow Agent to release the proceeds of the Final Closing to the Company, less fees and expenses due to the Placement Agent and the Subscribers
shall purchase and the Company shall sell the balance of the Common Stock and Warrants included in the Units (the “Final Closing” and such date, the “Final Closing Date”). Interest, if any, that has accrued with
respect to the Final Closing Amount while in escrow shall also be distributed to the Company at the Final Closing and Subscribers will have no right to such interest. Prior to the Final Closing and in any event not more than two (2) business days
after Stockholder Approval, the Company shall file with the Secretary of State of the State of Delaware an amendment to the Company’s Certificate of Incorporation (the “Amended Certificate of Incorporation”) increasing the
authorized number of shares of Common Stock in an amount sufficient to issue the balance of such Securities (including subsequent exercises of the Warrants). The receipt of Stockholder Approval (as further described below) is a condition to the
Final Closing and such condition may not be waived by the Subscribers. 
  
 1.4 Stockholder Approval. The Company is required to seek the Stockholder Approval within 90 days of the Initial Closing Date (the “Stockholder Approval Termination Date”). The Stockholder Approval Termination Date
may be extended by mutual agreement between the Placement Agent and the Company, without notice to Subscribers, for up to an additional 45 days. If Stockholder Approval is not obtained by the Stockholder Approval Termination Date, as extended as
provided herein, then the obligation of the Subscriber to purchase in the Final Closing the balance of the Securities subscribed for by such Subscriber and not issued at the Initial Closing and to remit the Final Closing Amount will be terminable at
the 
  

 3 

 option of the Subscriber, and if terminated, such obligations of the Subscriber to purchase in the Final Closing the
balance of the Securities subscribed for by such Subscriber and not issued at the Initial Closing shall be deemed null and void. In addition, in the event Stockholder Approval has not been obtained by the Company on or before the Stockholder
Approval Termination Date, the Company will pay to the Subscribers on a pro-rata basis, as liquidated damages and not as a penalty, an aggregate cash payment among all Subscribers equal to 2% of the Initial Closing Amount distributed pro-rata among
all Subscribers at the Initial Closing Date, for each week beyond the Stockholder Approval Termination Date that Stockholder Approval is not obtained, up to a maximum of 8% of the Initial Closing Amount distributed pro-rata among all Subscribers in
the aggregate, such that upon the completion of four weeks after the Stockholder Approval Termination Date, these liquidated damages will equal 8% of the Initial Closing Amount in the aggregate and no further liquidated damages will be owed pursuant
to this provision. 
  
 1.5 Offering Termination Date.
Unless terminated earlier in the Placement Agent’s or the Company’s sole discretion, the Offering will expire on the earlier to occur of the Final Closing Date and 11:59 p.m. New York City time on June 30, 2004 (subject to extension at the
Company’s sole discretion without notice to the Subscribers) (the “Offering Termination Date”). 
  
 1.6 Prior to each of the Initial Closing and Final Closing, the Initial Closing Amount and the Final Closing Amount, respectively, will be deposited in a
segregated escrow account with the Escrow Agent pursuant to the instructions provided below in this Section 1.6. Subject to the terms and conditions of this Agreement (including, without limitation, the Company’s and the Placement Agent’s
option, each at its sole discretion, to refuse to accept Subscriptions from any Subscriber and, in the case of Subscriptions for Securities to be issued at the Final Closing, the requirement that the Company obtain Stockholder Approval prior to the
Final Closing), the Subscriber hereby subscribes for and agrees to purchase from the Company such number of Units and the Company agrees to sell such number of Units to the Subscriber as is set forth upon the signature page hereof at the Offering
Price (as defined on the signature page hereto). Pursuant to Sections 1.2 and 1.3, the Initial Closing Amount and Final Closing Amount, respectively, is payable by wire transfer, certified bank check, personal or business check, or money order made
payable to “US Bank Trust National Association Corporation Trust, (the “Escrow Agent”) F/B/O InSite Vision Incorporated.” Subscribers paying by wire transfer should direct such wire transfer to:

	II.	REPRESENTATIONS, WARRANTIES AND COVENANTS OF SUBSCRIBERS 

  
 Each Subscriber hereby represents, warrants and covenants to the Company, severally and not jointly with any other Subscriber, as follows:

  
 2.1 The Subscriber recognizes and acknowledges that the
purchase of the Units involves a high degree of risk including, but not limited to, the following: (i) an investment in the Company is highly speculative, and only Subscribers who can afford the loss of their entire investment should consider
investing in the Company and the Units; (ii) the Subscriber may not be able to liquidate his/her/its investment; (iii) transferability of the Common Stock and Warrants included in the Units, and the common stock issuable upon exercise of the
Warrants (collectively the “Securities”) is extremely limited; (iv) in the event of a disposition of the Securities, the Subscriber could sustain the loss of his/its entire investment; (v) the Company has not paid any dividends on
its Common Stock since inception and does not anticipate the payment of dividends in the foreseeable future; and (vi) the Company may not obtain the Stockholder Approval, and accordingly, if Stockholder Approval is not obtained the Company will be
unable to conduct the Final Closing and the Subscriber will not be able to purchase Units in the Final Closing. 
  
 2.2 The Subscriber represents that the Subscriber is an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated
under the Securities Act of 1933, as amended (the “Securities Act”), as indicated by the Subscriber’s responses to the questions contained in Article VIII hereof which responses are true and correct as of the date hereof and
shall be true and correct as of each of the Initial Closing and Final Closing, and that the Subscriber is able to bear the economic risk of an investment in the Company. If the Subscriber is a natural person, the Subscriber has reached the age of
majority in the state or other jurisdiction in which the Subscriber resides, has adequate means of providing for the Subscriber’s current financial needs and contingencies, is able to bear the substantial economic risks of an investment in the
Securities for an indefinite period of time, has no need for liquidity in such investment and, at the present time, could afford a complete loss of such investment. 
  
 2.3 The Subscriber hereby acknowledges and represents that (i) the Subscriber is knowledgeable, sophisticated and has
experience in making, and is qualified to make, decisions with respect to investments representing an investment decision like that involved in the purchase of the Units and has prior investment experience, including investment in securities which
are non-listed, unregistered and/or not traded on the NASDAQ National or SmallCap 
  

 5 

 Market or listed on AMEX; (ii) the Subscriber recognizes the highly speculative nature of this investment, that an
investment in the Units and the underlying Securities involves a significant degree of risk, that the market price of the Common Stock has been and continues to be volatile, and Subscriber has carefully evaluated the risks of an investment in the
Units; and (iii) the Subscriber is able to bear the economic risk of an investment in the Units and the potential loss of such investment, which risk the Subscriber hereby assumes. 
  
 2.4 The Subscriber hereby acknowledges that he/she/it has received and carefully reviewed this Agreement, the confidential
offering memorandum prepared by the Company and dated as of March 5, 2004, as amended or supplemented, including all documents attached thereto or incorporated by reference therein, including the following documents filed by the Company with the
Securities and Exchange Commission (the “SEC” or the “Commission”, and such documents, the “SEC Filings”): SEC Form 10-K, filed March 31, 2003; SEC Form 10-K/A filed April 29, 2003; SEC Forms 10-Q

offering memorandum, including the SEC Filings and all other exhibits and information incorporated by reference therein is referred to herein as the “Memorandum”). Any information that the Company subsequently files with the SEC
that is incorporated by reference will automatically update and supersede any previous information that is part of this Memorandum. The Subscriber further represents that the Subscriber has been furnished by the Company during the course of this
transaction with all information regarding the Company which the Subscriber, its investment advisor, attorney and/or accountant has requested or desired to know, has been afforded the opportunity to ask questions of and receive answers from duly
authorized officers or other representatives of the Company concerning the terms and conditions of the Offering, and has received any additional information which the Subscriber has requested. 
  
 2.5 (a) The Subscriber has relied solely upon the information provided by the
Company in making the decision to invest in the Units. The Subscriber is familiar with and understands the terms of the Offering, including the rights to which the Subscriber is entitled under this Agreement. In evaluating the suitability of an
investment in the Company, the Subscriber has not relied upon any representation or other information (whether oral or written) from the Company, or any agent, employee or affiliate of the Company other than as set forth in the Memorandum and the
results of Subscriber’s own independent investigation. Subscriber understands and acknowledges that nothing in this Agreement, the Memorandum or any other materials provided to Subscriber in connection with the Subscription for the Units or
sale of the Securities constitutes investment, tax or legal advice. To the extent deemed necessary or advisable by Subscriber in his/her/its sole discretion, the Subscriber has retained, at his/her/its sole expense, and relied upon appropriate
professional advice regarding the investment, tax and legal merits and consequences of this Agreement and its purchase of the Units hereunder. 
  

 6 

 (b) The Subscriber represents that no Units or other securities were offered or sold to it by means of
any form of general solicitation or general advertising, and in connection therewith the Subscriber did not: (A) receive or review any advertisement, article, notice or other communication published in a newspaper or magazine or similar media or
broadcast over television or radio whether closed circuit, or generally available; or (B) attend any seminar meeting or industry or Subscriber conference whose attendees were invited by any general solicitation or general advertising. 
  
 2.6 The Subscriber hereby acknowledges that the Offering has not been
reviewed, recommended or endorsed by the United States Securities and Exchange Commission or any state securities regulatory authority or other governmental body or agency, since the Offering is intended to be exempt from the registration
requirements of Section 5 of the Securities Act pursuant to Regulation D promulgated under the Securities Act. The Subscriber shall not sell or otherwise transfer the Units unless such transfer is registered under the Securities Act or unless an
exemption from such registration is available. The Subscriber understands that if required by the laws or regulations or any applicable jurisdictions, the Offering contemplated hereby will be submitted to the appropriate authorities of such state(s)
for registration of exemption therefrom. 
  
 2.7 The Subscriber
understands and acknowledges that neither the Units nor the Securities have been registered under the Securities Act on reliance of a claimed exemption under the provisions of the Securities Act which depends, in part, upon the Subscriber’s
investment intention and the truth and accuracy of, and Subscriber’s compliance with, the representations, warranties, acknowledgments and covenants of Subscriber set forth herein. In this connection, the Subscriber hereby represents that the
representations, warranties, acknowledgments and covenants of Subscriber set forth herein are true and accurate, Subscriber will comply with the covenants set forth herein, and the Subscriber is purchasing the Units and underlying Securities for the
Subscriber’s own account for investment purposes only and not with a view toward the resale or distribution to others and has no contract, undertaking, agreement or other arrangement, in existence or contemplated, to sell, pledge, assign or
otherwise transfer the Units or underlying Securities to any other person. The Subscriber, if an entity, also represents that it was not formed for the purpose of purchasing the Units or underlying Securities. The Subscriber has no current plans to
effect a “change of control” of the Company, as such term is understood in Rule 13d of the Exchange Act. 
  
 2.8 The Subscriber understands that neither the Units nor the Securities will be registered or available for sale in the public markets except as
specifically provided herein, and Rule 144 promulgated under the Securities Act (“Rule 144”) requires, among other conditions, a one-year holding period for non-affiliates of the Company prior to the resale (in limited amounts) of
securities acquired in a non-public offering without having to satisfy the registration requirements under the Securities Act. The Subscriber understands and hereby acknowledges that the Company is under no obligation to register any of the Units or
Securities under the Securities Act or any state securities or “blue sky” laws or assist the Subscriber in obtaining an exemption from various registration requirements, other than as set forth in Article VI herein. The Subscriber agrees
to hold the Company and its directors, officers, employees, controlling persons and agents and their respective heirs, representatives, successors and assigns harmless 
  

 7 

 and to indemnify them against all liabilities, costs and expenses incurred by them as a result of (i) any
misrepresentation made by the Subscriber contained in this Agreement (including the Confidential Subscriber Questionnaire contained in Article VIII herein), (ii) any sale or distribution by the Subscriber in violation of the Securities Act or any
applicable state securities or “blue sky” laws or (iii) any untrue statement of a material fact made by the Subscriber and contained herein (including the Confidential Subscriber Questionnaire contained in Article VIII herein) or omission
of a material fact asked for by such questionnaire necessary to make such statements made by the Subscriber and contained herein (including the Confidential Subscriber Questionnaire contained in Article VIII herein), in light of the circumstances in
which they are made, not misleading. 
  
 2.9 The Subscriber
consents to the placement of a legend on any certificate or other document evidencing the Units substantially as set forth below, that such Units have not been registered under the Securities Act or any state securities or “blue sky” laws
and setting forth or referring to the restrictions on transferability and sale thereof contained in this Agreement. The Subscriber is aware that the Company will make a notation in its appropriate records and with its transfer agent with respect to
the restrictions on the transferability of the Units. 
  
 THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND
RESALE AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE
REASONABLY SATISFACTORY TO THE COMPANY, REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT. 
  
 2.10 The Subscriber agrees to supply the Company, within five (5) days after
the Subscriber receives the request therefore from the Company, with such additional information concerning the Subscriber as the Company deems necessary or advisable. 
  
 2.11 The Subscriber hereby represents that the address of the Subscriber furnished by Subscriber on the signature page
hereof is the Subscriber’s principal residence if Subscriber is an individual or its principal business address if it is a corporation or other entity. 
  
 2.12 The Subscriber represents that (i) the Subscriber has full right, power, authority and capacity (corporate, personal, statutory and otherwise) to
execute, deliver, and perform this Agreement and to purchase the Securities and has taken all action necessary to authorize the execution, delivery and performance of this Agreement; and (ii) this Agreement constitutes the legal, valid and binding
obligation of the Subscriber, enforceable against the Subscriber in accordance with its terms. 
  

 8 

 2.13 If the Subscriber is a corporation, partnership, limited liability company, trust, employee benefit
plan, individual retirement account, Keogh Plan, or other entity (a) it is authorized and qualified to become an Subscriber in the Company and the person signing this Agreement on behalf of such entity has been duly authorized by such entity to do
so and (b) it is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization. 
  
 2.14 The Subscriber acknowledges that if he or she is a Registered Representative of an NASD member firm, he or she must give such firm the notice
required by the NASD Rules of Fair Practice, receipt of which must be acknowledged in accordance with such rules. 
  
 2.15 The Subscriber acknowledges and agrees that it shall not be entitled to seek any remedies with respect to the Offering from any party other than the
Company. 
  
 2.16 The Subscriber understands, acknowledges and
agrees with the Company that this Subscription may be rejected, in whole or in part, by the Company or the Placement Agent, in each of their sole and absolute discretion, at any time before the Initial Closing Date notwithstanding prior receipt by
the Subscriber of notice of acceptance of the Subscriber’s Subscription. Subscriptions accepted at the Initial Closing Date shall be binding on the Company. For clarification, the Company and the Placement Agent cannot refuse to accept the any
Subscriber’s Final Closing Amount after the Company has accepted such Subscriber’s Initial Closing Amount so long as the Final Closing occurs. 
  
 2.17 The Subscriber understands, acknowledges and agrees with the Company that, except as otherwise set forth herein, the Subscription hereunder is
irrevocable by the Subscriber, that, except as required by law, the Subscriber is not entitled to cancel, terminate or revoke this Agreement or any agreements of the Subscriber hereunder and that this Agreement and such other agreements shall
survive the death or disability of the Subscriber and shall be binding upon and inure to the benefit of the parties and their heirs, executors, administrators, successors, legal representatives and permitted assigns. If the Subscriber is more than
one person, the obligations of the Subscriber hereunder shall be joint and several and the agreements, representations, warranties and acknowledgments herein contained shall be deemed to be made by and be binding upon each such person and his/her
heirs, executors, administrators, successors, legal representatives and permitted assigns. 
  
 2.18 The Subscriber understands, acknowledges and agrees with the Company that the Offering is intended to be exempt from registration under the Securities Act by virtue of Section 4(2) of the Securities Act and the
provisions of Regulation D thereunder, and/or the provisions of Regulation S, which is in part dependent upon the truth, completeness and accuracy of the statements made by the Subscriber. 
  

 9 

 2.19 The Subscriber understands, acknowledges and agrees with the Company that, there can be no assurance
that the Subscriber will be able to sell or dispose of the Securities. It is understood that in order not to jeopardize the Offering’s exempt status under Section 4(2) of the Securities Act and Regulation D, as well as Regulation S, in addition
to any other restrictions on transfer set forth herein or in the Warrants, the Company may, at a minimum, require any transferee to fulfill the Subscriber suitability requirements thereunder and make the representations, warranties and covenants of
Subscriber hereunder. 
  
 2.20 The Subscriber agrees that during
the period from the date that Subscriber was first contacted with respect to the Offering through the last date upon which Subscriber holds any Units, the Subscriber will not directly or indirectly, through related parties, affiliates or otherwise
sell “short” or “short against the box” (as those terms are generally understood) any equity security of the Company or take any action with respect to any equity security of the Company which would violate the Securities Act or
the rules and regulations promulgated thereunder. 
  
 2.21 The
Subscriber acknowledges and agrees that the information contained in this Agreement, the Memorandum or otherwise made available to the Subscriber by the Company (collectively, the “Confidential Information”) is to be used solely for
the purpose of evaluating a possible investment in the Units and is confidential and non-public and agrees that all such Confidential Information shall be kept in confidence by the Subscriber and neither used by the Subscriber for the
Subscriber’s personal benefit (other than in connection with evaluating a possible investment in the Units) nor disclosed to any third party for any reason and in any manner, notwithstanding that a Subscriber’s subscription may not be
accepted by the Company; provided, however, that this obligation shall not apply to any such Confidential Information that (i) is part of the public knowledge or literature and readily accessible at the date hereof (except as a result of a breach of
this provision), or (ii) becomes part of the public knowledge or literature and readily accessible by publication (except as a result of a breach of this provision). 
  
 2.22 If the Subscriber is purchasing the Units in a fiduciary capacity for another person or entity, including without
limitation a corporation, partnership, trust or any other entity, the Subscriber has been duly authorized and empowered to execute this Agreement and all other subscription documents, and such other person or entity fulfills all the requirements for
purchase of the shares as such requirements are set forth herein, concurs in the purchase of the Securities and agrees to be bound by the obligations, representations, warranties and covenants contained herein. Upon request of the Company, the
Subscriber will provide true, complete and current copies of all relevant documents creating the Subscriber, authorizing its investment in the Company and/or evidencing the satisfaction of the foregoing. 
  
 2.23 No authorization, approval, consent or license of any person is required
to be obtained for the purchase of the Units by the Subscriber, other than as have been obtained and are in full force and effect. The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby
will not, result in any violation of or constitute a default under any material agreement or other instrument to which the Subscriber is a party or by which the Subscriber or any of its properties are bound, or to the best of the Subscriber’s
knowledge, any permit, franchise, judgment, order, decree, statute, rule or regulation to which the Subscriber or any of its businesses or properties is subject. 
  

 10 

 2.24 The representations, warranties and agreements of the Subscriber contained herein, in the
Confidential Subscriber Questionnaire and in any other writing delivered in connection with the transactions contemplated hereby shall be true and correct in all respects on and as of the Initial Closing Date and Final Closing Date as if made on and
as of such date and shall survive the execution and delivery of this Agreement and the purchase of the Securities. Subscriber agrees to notify the Company as promptly as possible of any change in any of the foregoing information until such time as
the Subscriber has sold all of its Securities. 
  
 2.25 The
Subscriber hereby covenants with the Company not to make any sale of the Securities under the Registration Statement without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied, and further agrees to
comply with reasonable requests of the Company or its transfer agent to provide additional information and representations concerning such sale.

Securities Law of 1968: 
  
 “THE SALE OF THE SECURITIES THAT
ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE
QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE
QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.” 
  
 2.27 The Subscriber is not an adverse party to the Company in any lawsuit involving the Company. 
  

	III.	REPRESENTATIONS, WARRANTIES AND COVENANTS BY AND OF THE COMPANY 

  
 The Company hereby represents and warrants to the Subscriber that (for purposes of this Article III, references to “Memorandum” shall mean the
Memorandum excluding the SEC Filings): 
  
 3.1 Organization,
Good Standing and Qualification. As of each of the Initial Closing and Final Closing, the Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has full corporate power and
authority to 
  

 11 

 conduct its business as currently conducted. The Company is duly qualified as a foreign corporation to do business and is
in good standing in every jurisdiction in which the property owned or leased by it or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or in good standing would
not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, operations, condition (financial or otherwise), assets, or results of operations of the Company and its Subsidiaries (as defined below)
as a whole (a “Material Adverse Effect”). 
  
 3.2

not aware that any of its employees, including the employees of its Subsidiaries, are obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any
court or administrative agency, that the Company believes would materially interfere with the use of the employee’s best efforts to promote the interests of the Company and/or its Subsidiaries or that would conflict with the business of the
Company and/or its Subsidiaries as currently conducted. To the Company’s knowledge, neither the execution and delivery of this Agreement, nor the carrying on of the business of the Company and its Subsidiaries by the employees of the Company
and its Subsidiaries, nor the conduct of the business of the Company and its subsidiaries, as currently conducted, will conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any such employee is now obligated.

 (c) make every
reasonable effort to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time;

conformity with written information furnished to the Company by or on behalf of such Holder or person controlling such Holder and stated to be specifically for use in preparation of such registration statement, prospectus or any supplement or

in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.7(c) below), arising out of or based on any untrue statement of a material fact contained in any registration
statement, prospectus, or any amendment or supplement thereof, incident to any such registration, qualification or compliance, or based on any omission to state therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in light of the circumstances in which they were made, in each case to the extent, but only to the extent, that such untrue statement or omission thereof is made in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Holder and stated to be specifically for use in preparation of such registration statement, prospectus or any amendment or supplement thereto, and the Holder will reimburse the Company, its
directors and officers, and each person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating, defending, settling, compromising or paying any such claim, loss, damage, liability,
expense or action as incurred. Notwithstanding the foregoing, in no event shall a Holder be liable for any such claims, losses, damages or liabilities in excess of the net proceeds received by such Holder in the Offering, except in the event of
fraud or intentional misrepresentation by such Holder. 
  
 (c)
Each party entitled to indemnification under this Section 6.7 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought, provided that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement,
unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. Subject to provisions hereinafter stated, in case any such action is brought against any Indemnified Party and such Indemnified Party
seeks or intends to seek indemnity from an Indemnifying Party, the Indemnifying Party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense
thereof with counsel reasonably satisfactory to such Indemnified Party; provided, however, if the defendants in any such action include both the Indemnified Party 
  

 23 

 and the Indemnifying Party, and the Indemnifying Party and the Indemnified Party, based upon the advice of such
Indemnified Party’s counsel, shall have reasonably concluded that there may be a conflict of interest between the positions of the Indemnifying Party and the Indemnified Party in conducting the defense of any such action or that there may be
legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the Indemnifying Party, the Indemnified Party or parties shall have the right to select separate counsel to assume such
legal defenses and to otherwise participate in the defense of such action on behalf of such Indemnified Party or parties. Upon receipt of notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense of such
action and approval by the Indemnified Party of counsel, the Indemnifying Party will not be liable to such Indemnified Party under this Section 6.7 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with
the defense thereof unless (i) the Indemnified Party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the Indemnifying
Party shall not be liable for the expenses of more than one separate counsel, approved by such Indemnifying Party in the case of paragraph (a), representing the Indemnified Parties who are parties to such action or (ii) the Indemnifying Party shall
not have employed counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall
be at the expense of the Indemnifying Party. In no event shall any Indemnifying Party be liable in respect of any amounts paid in settlement of any action unless the Indemnifying Party shall have approved the terms of such settlement; provided
that such approval shall not be unreasonably withheld.  
  
 (d) If the indemnification provided for in this Section 6.7 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement
which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact or the inaccurate representation and/or warranty relates to information supplied by the Indemnifying Party or by the Indemnified Party
and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, in no event shall a Holder be liable for any such claims, losses, damages or
liabilities pursuant to this paragraph 6.7(b) in excess of the net proceeds received by such Holder in the Offering, except in the event of fraud or intentional misrepresentation by such Holder. 
  
 6.8 (a) Notwithstanding any other provision of this Agreement, each Holder
agrees that, upon receipt of any notice from the Company of the happening of any event requiring 
  

 24 

 the preparation of a supplement or amendment to a prospectus relating to Registrable Securities or the filing of an
appropriate report with the SEC pursuant to the Exchange Act, so that, as thereafter delivered to the Holders, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement contemplated by Section 6.2 or 6.3 (as applicable) until its receipt of
copies of the supplemented or amended prospectus from the Company or confirmation of the filing of such report with the SEC by the Company, any such prospectus to be forwarded promptly to the Subscriber by the Company, and, if so directed by the
Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 

 
 (b) Notwithstanding any other provision of this Agreement, each Holder
shall suspend, upon request of the Company, any disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 6.2 and 6.3 (as applicable) during any periods not to exceed 60 days in the aggregate
within any one 12-month period when the Company reasonably determines in good faith that offers and sales pursuant thereto should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the
disclosure that would be required in such a prospectus is premature, would have an adverse effect on the Company or is otherwise inadvisable. 
  
 (c) As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in writing or as shall be required in connection with any registration, qualification or compliance referred to in this Article VI. 
  
 (d) Each Holder hereby covenants with the Company not to make any sale of the
Registrable Securities without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied. 
  
 (e) Each Holder acknowledges and agrees that the Registrable Securities sold pursuant to the Registration Statement described in this Section are not
transferable on the books of the Company unless the stock certificate submitted to the transfer agent evidencing such Registrable Securities is accompanied by a certificate reasonably satisfactory to the Company to the effect that (i) the
Registrable Securities have been sold in accordance with such Registration Statement and (ii) the requirement of delivering a current prospectus has been satisfied. 
  
 (f) Each Holder agrees not to take any action with respect to any distribution deemed to be made pursuant to such
registration statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law. 
  
 (g) At the end of the period during which the Company is obligated to keep the Registration Statement current and effective as described above, the
Holders of Registrable 
  

 25 

 Securities included in the Registration Statement shall discontinue sales of shares pursuant to such Registration
Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which
remain unsold immediately upon receipt of such notice from the Company. 
  
 6.9 With a view to making available to the Holders the benefits of certain rules and regulations of the Commission which at any time permit the sale of the Registrable Securities to the public without registration, the Company shall use its
reasonable best efforts to: 
  
 (a) make and keep public
information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times; 
  
 (b) file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and 
  
 (c) so long as a Holder owns any unregistered Registrable Securities, furnish
to such Holder, upon any reasonable request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other
reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration. 
  
 6.10 The rights to cause the Company to register Registrable Securities
granted to the Holders by the Company under Section 6.1 may be assigned in full by a Holder in connection with a transfer by such Holder of its Registrable Securities, but only if: (i) such transfer may otherwise be effected in accordance with
applicable securities laws; (ii) such Holder gives prior written notice of the proposed transfer to the Company including the name and address of such transferee and a copy of the transfer documents and agreements; (iii) such transferee agrees in
writing with the Company to be bound by and to comply with the terms and provisions of this Agreement; (iv) the transferee is an “accredited investor” as that term is defined in Rule 501 of Regulation D; and (v) such transfer is otherwise
in compliance with this Agreement. Except as specifically permitted by this Section 6.10, the rights of a Holder with respect to Registrable Securities as set forth herein shall not be transferable to any other Person, the Company may impose stop
transfer orders with respect to any such transfer or attempted transfer, and any such transfer or attempted transfer shall be null and void. 
  
 6.11 The Company shall use best efforts to cause all Registrable Securities covered by a Registration Statement to be listed on each securities exchange,
interdealer quotation system or other market on which similar securities issued by the Company are then listed. 
  
 6.12 With the written consent of the Company and the Holders holding at least a majority of the Registrable Securities that are then outstanding, any
provision of this Article VI may be waived (either generally or in a particular instance, either retroactively or prospectively 
  

 26 

 and either for a specified period of time or indefinitely) or amended. Upon the effectuation of each such waiver or
amendment, the Company shall promptly give written notice thereof to the Holders, if any, who have not previously received notice thereof or consented thereto in writing.

 Part
V REGISTRATION QUESTIONNAIRE 
  
 The following questions in this Part V
are specifically intended to provide information to the Company for the Company’s use in the preparation of the Registration Statement contemplated by the Subscription Agreement and for specific inclusion in such Registration Statement.

  
 PLEASE ANSWER EVERY QUESTION BELOW. If a question is inapplicable to you
or your answer is in the negative, please so state by inserting “N/A.” If you are in doubt whether a particular question requires an affirmative response from you, please furnish full particulars so that those persons responsible for
preparing the Registration Statement contemplated by the Subscription Agreement can determine whether any disclosure based on your answer is required. Information requested in this questionnaire is as of the date you complete the questionnaire,
unless otherwise indicated. Your furnishing such information does not necessarily mean that such information will be disclosed, although it may be disclosed. You are required to promptly provide the Company with any update to the information if
such information changes after the date hereof. 
  
 DEFINITIONS 
  
 Your answers to this
questionnaire should be made upon the basis of the following definitions of terms used in this questionnaire: 
  
 The term “beneficial owner” of a security includes any person who, directly or indirectly, through any contract, arrangement,
understanding, relationship or otherwise has or shares (1) voting power, which includes the power to vote, or direct the voting of, such security or (2) investment power, which includes the power to dispose or direct the disposition of
such security. A person may be regarded as having voting power of a security which is owned (i) by his spouse or minor children or by any of his relatives or his spouse’s relatives who share the same home with him, (ii) a partnership of which
he is a partner or (iii) a corporation of which he is a substantial stockholder. A person is also deemed to be the beneficial owner of shares which that person has the right to acquire within 60 days, including but not limited to any right to
acquire through the exercise of an option, through conversion of a security, pursuant to the power to revoke a trust or pursuant to the automatic termination of a trust. Please also disclose any other rights, which you have to acquire securities of
the Company on or before March 1, 2004. 
  

 34 

 The term “material,” when used to qualify a requirement for the furnishings of
information as to any subject, limits the information required to those matters about which the average prudent investor should reasonably be informed before buying or selling the securities of the Company. If you are in doubt as to the materiality
of certain information, you should relate sufficient facts to enable the Company and its advisors to reach a conclusion as to its materiality. 
  
 QUESTIONS 
  
 QUESTION 1: 
  
 State your present position or positions with the Company (if any), including membership on any audit, personnel, compensation or similar committee or committees; any positions held by you during the previous three
years; and any positions to which you have been elected or appointed but the duties of which you have not yet assumed. For each position, list the term or expected term of office. 
  
 ANSWER: 
  
 QUESTION 2: 
  
 Other than Securities that you will acquire in connection with the Offering, provide below information regarding the equity securities of the Company of which you are the “beneficial
owner.” Please refer to the definition of “beneficial owner,” above. Under the column “Nature of Ownership,” please indicate amounts of securities for which you have (a) sole voting power, (b) shared voting power, (c)
sole investment power, or (d) shared investment power. If your response covers any securities included because you have the right to acquire them on or before             , 2004,
please separately indicate the amount of such securities. Also, if you hold more than 5% of the Company’s securities pursuant to a voting trust or similar agreement, please separately state the amount of such securities held or to be held
pursuant to the trust or agreement, the duration of the agreement and the names and addresses of the voting trustees, outlining briefly their voting rights and other powers under the trust or agreement.

 QUESTION 8: 
  
 If you are affiliated with a broker-dealer, did you purchase the securities in the ordinary course of business? 
  
 ANSWER: 
  
 Yes             
                    No             
  
 QUESTION 9: 
  
 If you are affiliated with a broker-dealer, did you have any agreements or understandings, directly or indirectly, with any person to
distribute the securities at the time that you purchased the securities? 
  
 ANSWER: 
  
 Yes
            
                    No             
  
 Please note that the Commission takes the position that if you are a
broker-dealer, you are to be identified in the Registration Statement as an underwriter. In the “Plan of Distribution,” the Registration Statement will provide substantially as follows: 
  
 “The selling stockholders and any broker-dealers, agents or underwriters
that participate with the selling stockholders in the distribution of the issued and outstanding shares of common stock or the shares of stock issuable upon exercise of warrants may be deemed to be “underwriters” within the meaning of the
Securities Act, in which event any commissions received by these broker-dealers, agents or underwriters and any profits realized by the selling stockholders on the resales of the securities may be deemed to be underwriting commissions or discounts
under the Securities Act. If the selling stockholders are deemed to be underwriters, the selling stockholders may be subject to certain statutory and regulatory liabilities, including liabilities imposed pursuant to Sections 11, 12 and 17 of the
Securities Act and Rule 10b-5 under the Exchange Act.”

 QUESTION 10: 
  
 Are their specific individuals who have voting or investment control over the securities? 
  
 ANSWER: 
  
 Yes             
                    No             
  
 If you answered “yes”, please list the names of such individuals:

 Common Stock 
  
  

					
	No. A- [    ]	 	 	 	                 
Shares

  
 FOR VALUE RECEIVED,
INSITE VISION INCORPORATED., a Delaware corporation (the “Company”), hereby certifies that [            ], its designee or its permitted assigns is entitled to
purchase from the Company, at any time or from time to time commencing on                  , 2004 and prior to 5:00 P.M., New York City time, on
                 , 2009,
                             fully paid and non-assessable shares of common stock, $0.01 par value per
share, of the Company for an aggregate purchase price of [        ] ($            ). (Hereinafter, (i) said common stock, $0.01
par value per share, of the Company, is referred to as the “Common Stock”; (ii) the shares of the Common Stock (subject to adjustment as set forth herein) purchasable hereunder or under any other Warrant (as hereinafter defined) are
referred to as the “Warrant Shares”; (iii) the aggregate purchase price payable for the Warrant Shares purchasable hereunder is referred to as the “Aggregate Warrant Price”; (iv) the price payable (initially $0.75
per share subject to adjustment as set forth herein) for each of the Warrant Shares hereunder is referred to as the “Per Share Warrant Price”; (v) this Warrant, all similar Warrants issued on the date hereof and all warrants
hereafter issued in exchange or substitution for this Warrant or such similar Warrants are referred to as the “Warrants”; and (vi) the holder of this Warrant is referred to as the “Holder” and the holder of this
Warrant and all other Warrants and Warrant Shares are referred to as the “Holders” and Holders of more than fifty percent (50%) of the Warrant Shares then issuable upon exercise of then outstanding Warrants are referred to as the
“Majority of the Holders”). The Aggregate Warrant Price is not subject to adjustment. 

 This Warrant, together with warrants of like tenor, constituting in the aggregate Warrants to purchase
[            ] Warrant Shares, was originally issued pursuant to a Subscription Agreement (the “Subscription Agreement”) between the Company and the investor named
therein in connection with a private placement by the Company of its securities. By acceptance of this Warrant, the Holder agrees to comply with all applicable provisions of the Subscription Agreement 
  
 1. Exercise of Warrant. 
  
 (a) This Warrant may be exercised in whole at any time, or in part from time
to time, commencing on                  , 2004 and prior to 5:00 P.M., New York City time, on
                 , 2009 by the Holder by the surrender of this Warrant (with the subscription form at the end hereof duly executed) at the address set
forth in Section 10(a) hereof, together with proper payment of the Aggregate Warrant Price, or the proportionate part thereof if this Warrant is exercised in part, with payment for the Warrant Shares made by certified or official bank check payable
to the order of the Company; or 
  
 (b) If this Warrant is
exercised in part, this Warrant must be exercised for a number of whole shares of the Common Stock and the Holder is entitled to receive a new Warrant covering the Warrant Shares that have not been exercised and setting forth the proportionate part
of the Aggregate Warrant Price applicable to such Warrant Shares. Upon surrender of this Warrant in connection with the exercise of this Warrant pursuant to the terms hereof, the Company will (i) issue a certificate or certificates in the name of
the Holder for the largest number of whole shares of the Common Stock to which the Holder shall be entitled upon such exercise and, if this Warrant is exercised in whole, in lieu of any fractional share of the Common Stock to which the Holder shall
be entitled, pay to the Holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board of Directors of the Company shall determine), and (ii) deliver the other securities and properties
receivable upon the exercise of this Warrant, or the proportionate part thereof, if this Warrant is exercised in part, pursuant to the provisions of this Warrant. 
  
 2. Reservation of Warrant Shares; Listing. 
  
 The Company agrees that, prior to the expiration of this Warrant, the Company shall at all times (a) have authorized and in
reserve, and shall keep available, solely for issuance and delivery upon the exercise of this Warrant, the shares of the Common Stock and other securities and properties as from time to time shall be receivable upon the exercise of this Warrant,
free and clear of all restrictions on sale or transfer, other than under Federal or state securities laws, and free and clear of all preemptive rights and rights of first refusal and (b) if the Company hereafter lists its Common Stock on any
national securities exchange, the NASDAQ National Market or the NASDAQ Smallcap Market, use its commercially reasonable efforts to keep the Warrant Shares authorized for listing on such exchange upon notice of issuance. 
  

 2 

 3. Certain Adjustments. 
  
 (a) If, at any time or from time to time after the date of this Warrant, the Company shall issue or distribute to all
holders of shares of Common Stock by reason of their ownership thereof evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (excluding a subdivision, combination or reclassification, or dividend or
distribution payable in shares of Common Stock, referred to in subsection 3(b), and also excluding cash dividends or cash distributions paid out of net profits legally available therefor (any such non-excluded event being herein called a
“Special Dividend”)), the Per Share Warrant Price shall be adjusted (effective immediately prior to such issuance or distribution but after the record date for such issuance or distribution) by multiplying the Per Share Warrant
Price then in effect by a fraction, the numerator of which shall be the Current Market Price in effect on the record date for such issuance or distribution less the fair market value (as determined in good faith by the Company’s Board of
Directors) of the evidence of indebtedness, cash, securities or property, or other assets issued or distributed in such Special Dividend applicable to one share of Common Stock and the denominator of which shall be the Current Market Price in effect
on the record date for such issuance or distribution. An adjustment made pursuant to this subsection 3(a) shall become effective immediately prior to the payment date but after the record date of any such Special Dividend. If such dividend,
distribution, subdivision or combination is not consummated in full, the Per Share Warrant Price and Warrant Shares shall be readjusted accordingly. 
  
 (b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii) combine or reverse-split its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital
stock of the Company, then the Per Share Warrant Price and the number of Warrant Shares shall forthwith be proportionately decreased and increased, respectively, in the case of a subdivision, distribution or stock dividend, or proportionately
increased and decreased, respectively, in the case of a combination or reverse stock split. The Aggregate Warrant Price payable for the then total number Warrant Shares available for exercise under this Warrant shall remain the same. Adjustments
made pursuant to this subsection 3(b) shall become effective on the record date in the case of a dividend or distribution, and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.
If such dividend, distribution, subdivision or combination is not consummated in full, the Per Share Warrant Price and Warrant Shares shall be readjusted accordingly. 
  
 (c) In case of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a
party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of all or substantially all of the assets of the Company, or in the case of any statutory exchange
of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company but excluding any exchange of securities or merger with another corporation in which the Company is a
continuing corporation and that does not result in any reclassification of or similar change in the Common Stock), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of
securities, cash or other property which the Holder would have owned or 
  

 3 

 have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory
exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary,
appropriate adjustment shall be made in the application of the provisions set forth in this Article III with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Article III
shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection
3(c) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The Company shall require the issuer of any shares of stock or other securities or property thereafter
deliverable on the exercise of this Warrant to be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and
of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than twenty (20) days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of
securities shall be deemed a consolidation or merger for the foregoing purposes. 
  
 (d) No adjustment in the Per Share Warrant Price shall be required unless such adjustment would require an increase or decrease of at least $0.03 per share of Common Stock; provided, however, that any
adjustments which by reason of this subsection 3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further, however, that adjustments shall be required and made in
accordance with the provisions of this Article III (other than this subsection 3(d)) not later than such time as may be required in order to preserve the tax-free nature of a distribution, if any, to the Holder of this Warrant or Common Stock
issuable upon the exercise hereof. All calculations under this Article III shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Article III to the contrary notwithstanding, the Company shall be
entitled to make such reductions in the Per Share Warrant Price, in addition to those required by this Article III, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights
to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. 
  
 (e) Whenever the Per Share Warrant Price is adjusted as provided in this Article III and upon any modification of the rights of a Holder of Warrants in
accordance with this Article III, the Company shall promptly prepare a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of
the Warrants. 
  
 (f) If the Board of Directors of the Company
shall declare any dividend or other distribution with respect to the Common Stock other than a cash distribution out of earned surplus, the Company shall mail notice thereof to the Holders of the Warrants not less than ten (10) days prior to the
record date fixed for determining stockholders entitled to participate in such dividend or other distribution. 
  

 4 

 (g) If, as a result of an adjustment made pursuant to this Article III, the Holder of any Warrant
thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and
shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Warrant Price between or among shares or such classes of capital stock or shares of Common
Stock and other capital stock. 
  
 (h) In case any event shall
occur as to which the other provisions of this Article III are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential
intent and principles of the adjustments set forth in this Article III then, in each such case, the Board of Directors of the Company shall in good faith determine the adjustment, if any, on a basis consistent with the essential intent and
principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon such determination, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described
therein. 
  
 4. Fully Paid Stock; Taxes. The shares of the Common
Stock represented by each and every certificate for Warrant Shares delivered on the exercise of this Warrant shall, subject to compliance by the Holder with the terms hereof, at the time of such delivery, be duly authorized, validly issued and
outstanding, fully paid and nonassessable, and not subject to preemptive rights or rights of first refusal imposed by any agreement to which the Company is a party, and the Company will take all such actions as may be necessary to assure that the
par value, if any, per share of the Common Stock is at all times equal to or less than the then Per Share Warrant Price. The Company shall pay, when due and payable, any and all Federal and state stamp, original issue or similar taxes which may be
payable in respect of the issue of any Warrant Share or any certificate thereof to the extent required because of the issuance by the Company of such security. 
  

5. Registration Under Securities Act. 
  
 (a) The Holder shall have the right to participate in the registration rights granted to purchasers of the Common Stock pursuant to Article VI of the
Subscription Agreement. By acceptance of this Warrant, the Holder agrees to comply with the provisions in Article VI of the Subscription Agreement to same extent as if it were a party thereto. 
  
 (b) Until all of the Warrant Shares and any shares of Common Stock issuable
thereunder have been sold under a Registration Statement or pursuant to Rule 144(k), so long as the Company’s Common Stock remains registered under the Securities Act, the Company shall use its commercially reasonable efforts to file with the
SEC all current reports and the information as may be necessary to enable the Holder to effect sales of its shares in reliance upon Rule 144(k) promulgated under the Securities Act. 
  

 5 

 6. Investment Intent; Limited Transferability. 
  
 (a) By accepting this Warrant, the Holder represents to the Company that it
understands that this Warrant and any securities obtainable upon exercise of this Warrant have not been registered for sale under Federal or state securities laws and are being offered and sold to the Holder pursuant to one or more exemptions from
the registration requirements of such securities laws. In the absence of an effective registration of such securities or an exemption therefrom, any certificates for such securities shall bear the legend set forth on the first page hereof. The
Holder understands that it must bear the economic risk of its investment in this Warrant and any securities obtainable upon exercise of this Warrant for an indefinite period of time, as this Warrant and such securities have not been registered under
Federal or state securities laws and therefore cannot be sold unless subsequently registered under such laws, unless an exemption from such registration is available. The Holder further represents to the Company, by accepting this Warrant, that it
has full power and authority to accept this Warrant and make the representations set forth herein. 
  
 (b) The Holder, by its acceptance of this Warrant, represents to the Company that it is acquiring this Warrant and will acquire any securities obtainable
upon exercise of this Warrant for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof in violation of the Securities Act. The Holder agrees, by acceptance of this Warrant, that this Warrant
and any such securities will not be sold or otherwise transferred unless (i) a registration statement with respect to such transfer is effective under the Securities Act and any applicable state securities laws or (ii) such sale or transfer is made
pursuant to one or more exemptions from the Securities Act. 
  
 (c) In addition to the limitations set forth in Article I and in accordance with the legend on the first page hereof, this Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions
of the Securities Act and the applicable state securities “blue sky” laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of
this Warrant as it appears on the Company’s books at any time as the Holder for all purposes. The Company shall permit any Holder of a Warrant or its duly authorized attorney, upon written request during ordinary business hours, to inspect and
copy or make extracts from its books showing the registered Holders of Warrant. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical
to those of the Holder unless, in each case, otherwise prohibited by applicable law. 
  
 (d) The Holder has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the Warrants
or the exercise of the Warrants; and (ii) the opportunity to request such additional information which the Company possesses or can acquire without unreasonable effort or expense. 
  
 (e) The Holder did not (i) receive or review any advertisement, article, notice or other communication published in a
newspaper or magazine or similar media or broadcast over television or radio, whether closed circuit, or generally available; or (ii) attend any seminar, meeting or investor or other conference whose attendees were, to such Holder’s knowledge,
invited by any general solicitation or general advertising. 
  

 6 

 (f) The Holder is an “accredited investor” within the meaning of Regulation D under the
Securities Act. Such Holder is acquiring the Warrants for its own account and not with a present view to, or for sale in connection with, any distribution thereof in violation of the registration requirements of the Securities Act, without
prejudice, however, to such Holder’s right, subject to the provisions of the Subscription Agreement and this Warrant, at all times to sell or otherwise dispose of all or any part of such Warrants and Warrant Shares. 
  
 (g) Either by reason of such Holder’s business or financial experience
or the business or financial experience of its professional advisors (who are unaffiliated with and who are not compensated by the Company or any affiliate, finder or selling agent of the Company, directly or indirectly), such Holder has the
capacity to protect such Holder’s interests in connection with the transactions contemplated by this Warrant and the Purchase Agreement. The Holder, by its acceptance of this Warrant, represents to the Company that it is able to fend for
itself, can bear the economic risk of its investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in this Warrant. Holder also represents it has not
been organized for the purpose of acquiring this Warrant. 
  
 7. Optional
Redemption. 
  
 (a) In the event that the average closing
price of the Common Stock for any 20 consecutive trading days on the AMEX is at least $1.50 (subject to proportionate adjustment for any stock splits, combinations, or similar events with respect to the Common Stock after the original issuance date
of this Warrant) (the “Redemption Price”), the Company shall be entitled to redeem the all outstanding and unexercised Warrants, or any portion of them, upon 30 business days’ written notice to the Holder, in which case the
Company shall be entitled to redeem all of the Warrants, or such portion of them identified in such notice and outstanding at the time of redemption, at a per Warrant redemption price equal to $0.75 (subject to proportionate adjustment for any stock
splits, combinations, or similar events with respect to the Common Stock after the original issuance date of this Warrant). The Holder agrees to return the certificate representing any redeemed Warrants to the Company upon their redemption. In the
event the certificate so returned represents a number of Warrants in excess of the number being redeemed, the Company shall as promptly as practicable issue to the Holder a new certificate for the number of unredeemed Warrants. 
  
 (b) So long as any Warrant Shares remain unregistered and such Warrant Shares
are not able to be immediately sold pursuant to a registration statement or Rule 144(k), the Company shall not be entitled to exercise its redemption rights pursuant to subsection 7(a) above. 
  
 8. Loss, etc., of Warrant. Upon receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver to the Holder a new Warrant of like date, tenor and denomination. 
  

 7 

 9. Warrant Holder Not Stockholder. This Warrant does not confer upon the Holder any right to vote on or
consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, nor any other rights or liabilities as a stockholder, prior to the exercise hereof; this Warrant does, however, require certain notices to
Holders as set forth herein. 
  
 10. Communication. No notice or
other communication under this Warrant shall be effective or deemed to have been given unless, the same is in writing and is mailed by first-class mail, postage prepaid, or via recognized overnight courier with confirmed receipt, addressed to:

  
 (a) the Company at InSite Vision
Incorporated, Chief Financial Officer, 965 Atlantic Avenue, Alameda, CA 94501, or other such address as the Company has designated in writing to the Holder. 
  
 or 
  
 (b) the Holder at the address of such Holder as set forth on the signature page to the Subscription Agreement or other such address as the
Holder has designated in writing to the Company. 
  
 11. Headings.
The headings of this Warrant have been inserted as a matter of convenience and shall not affect the construction hereof. 
  
 12. Applicable Law. This Warrant shall be governed by and construed in accordance with the law of the State of New York without giving effect to the
principles of conflicts of law thereof. 
  
 13. Amendment, Waiver,
etc. Except as expressly provided herein, neither this Warrant nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the party against whom enforcement of any such amendment,
waiver, discharge or termination is sought; provided, however, that any provisions hereof may be amended, waived, discharged or terminated upon the written consent of the Company and the Majority of the Holders.
