 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 $2.50 (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 $1.75 (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.

 IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by the undersigned duly authorized
officer, this      day of             , 2004.

	 	                 Shares

  
 FOR VALUE RECEIVED,
INSITE VISION INCORPORATED, a Delaware_ corporation (the “Company”), hereby certifies that Paramount Capital, Inc., 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 $         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 as compensation pursuant to the Engagement Agreement and all warrants hereafter issued in exchange or
substitution for this Warrant or such similar Warrants are referred to as the “Warrants”; (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

 on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last
reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the

dated February 12, 2004 (the “Engagement Agreement”) between the Company and Paramount Capital, Inc. in connection with a private placement by the Company of its securities (the “Units”). 
  
 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: 
  
 (i) by the surrender of this Warrant (with the subscription form at the end hereof duly executed) at the address set forth in subsection
9(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 
  
 (ii) by the surrender of this
Warrant (with the cashless exercise form at the end hereof duly executed) (a “Cashless Exercise”) at the address set forth in subsection 9(a) hereof. Pursuant to such Cashless Exercise, the aggregate purchase price for Warrant
Shares being purchased hereunder shall be paid by surrender of a number of Warrant Shares available for exercise under this Warrant that have a Current Market Value equal to the aggregate purchase price of the Warrant Shares being purchased as
determined herein. If the Holder elects the Cashless Exercise method of payment, the Company shall issue to Holder upon exercise a number of shares of Warrant Shares determined in accordance with the following formula: 
  

			
	  
 X=
	 	Y(A-B)
	 	    A

  
 where: X = the number of Warrant Shares to be issued to the Holder; 
  

 2 

			
	Y =	 	the number of Warrant Shares with respect to which the Holder is exercising its purchase rights under this Warrant;
		
	A =	 	the Current Market Value of one (1) share of the Warrant Shares on the date of exercise; and
		
	B =	 	the Per Share Warrant Price.

  
 No fractional shares
arising out of the above formula for determining the number of shares to be issued to the Holder shall be issued, and the Company shall in lieu thereof make payment to the Holder of cash in the amount of such fraction multiplied by the Current
Market Value of one (1) share of the Warrant Shares on the date of exercise. 
  
 (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. 
  
 (c) Notice of any transaction the closing of which would cause the Expiration
Date to occur shall be mailed to the Holders not less than ninety (90) days prior to the date of such closing, unless notice thereof has previously been given to the Holders pursuant to any other provision hereof. 
  
 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.

 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 
  

 4 

 owned or 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 $0.01 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. The Company may, but shall not be obligated to unless requested by a Majority of the Holders, obtain, at its expense, a certificate of a firm of independent
public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Warrant Price and the number of Warrant Shares in effect after such adjustment or the effect of
such modification, 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. 
  

 5 

 (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. 
  
 (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 between such purchasers and the Company that were entered into in connection with the sale of the Units. 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 
  

 6 

 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. 
  
 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 and in accordance with the legend set forth on the first page hereof. 
  
 (c) The Holder, by its acceptance of this Warrant, represents to the Company that that it is able to fend for itself, can bear the economic risk of its
investment, 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, has received and reviewed a copy of the Private Placement Memorandum provided by
the Company in connection with the Subscription Agreements and has had the opportunity to ask questions and receive answers from the Company regarding its business and financial condition. Holder also represents it has not been organized for the
purpose of acquiring this Warrant. 
  
 (d) This Warrant may not be
sold, transferred, assigned or hypothecated for six (6) months from the date hereof except (i) to any firm or corporation that succeeds to all or substantially all of the business of Paramount Capital, Inc., (ii) to any of the officers, employees,
associates or affiliated companies of Paramount Capital, Inc., or of any such successor firm, (iii) to any NASD member participating in the Offering or any officer or employee of any such NASD member or (iv) in the case of an individual, pursuant to
such individual’s last will and 
  

 7 

 testament or the laws of descent and distribution, and is so transferable only upon the books of the Company which the
Company shall cause to be maintained for such purpose. Provided however, in no event shall any portion of this Warrant be sold, transferred, assigned or hypothecated to more than 35 persons or entities. By acceptance of this Warrant each Holder
(including any transferee of this Warrant or any portion hereof), makes the representations set forth herein and further acknowledges that it has received and reviewed that certain Confidential Private Offering Memorandum of the Company, dated March
5, 2004, and any subsequent filings made by the Company with the Securities and Exchange Commission. 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 and obligations of the holder thereof shall be identical to those of the Holder. 
  
 7. 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. 
  
 8. 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.

  
 9. 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. 
  
 (b) the Holder at c/o Paramount Capital, Inc., 787 Seventh Avenue, 48th Floor, New York, NY 10019 or other such address as the Holder has designated in writing to the Company. 
  
 10. Headings. The headings of this Warrant have been inserted
as a matter of convenience and shall not affect the construction hereof. 
  
 11. 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. 
  

 8 

 12. 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.
