TRANSFER IS IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF SUCH ACT AND APPLICABLE LAWS OR SOME OTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND APPLICABLE LAWS IS AVAILABLE WITH RESPECT THERETO. 
 PREFERRED STOCK PURCHASE WARRANT 
  

			
	Warrant No. ___________	 	Number of Shares: 47,468
		 	Series C-l Preferred Stock

 HEMOSENSE, INC. 
 Effective as of _________, 2005 
 Void after
__________, 2012 
 1. Issuance. This Preferred Stock Purchase Warrant (the “Warrant”) is issued to
LIGHTHOUSE CAPITAL PARTNERS V, L.P. by HEMOSENSE, INC., a Delaware corporation (hereinafter with its successors called the “Company”).

 2. Purchase Price; Number of Shares. The registered holder of this Warrant (the “Holder”), commencing on
the date hereof, is entitled upon surrender of this Warrant with the subscription form annexed hereto duly executed, at the principal office of the Company, to purchase from the Company, at a price per share of $1.58 (the “Purchase
Price”), 47,468 fully paid and nonassessable shares of the Company’s Series C-l Preferred Stock, $0.001 par value (the “Preferred Stock”). 
 Until such time as this Warrant is exercised in full or expires, the Purchase Price and the securities issuable upon exercise of this Warrant are subject to adjustment as hereinafter provided. The person or persons in
whose name or names any certificate representing shares of Preferred Stock is issued hereunder shall be deemed to have become the holder of record of the shares represented thereby as at the close of business on the date this Warrant is exercised
with respect to such shares, whether or not the transfer books of the Company shall be closed. 
 3. Payment of Purchase Price.
The Purchase Price may be paid (i) in cash or by check, (ii) by the surrender by the Holder to the Company of any promissory notes or other obligations issued by the Company, with all such notes and obligations so surrendered being
credited against the Purchase Price in an amount equal to the principal amount thereof plus accrued interest to the date of surrender, or (iii) by any combination of the foregoing. 
 4. Net Issue Election. The Holder may elect to receive, without the payment by the Holder of any additional consideration, shares of
Preferred Stock equal to the value of this Warrant or any portion hereof by the surrender of this Warrant or such portion to the Company, with the net issue election notice annexed hereto duly executed, at the principal office of the Company.
Thereupon, the Company shall issue to the Holder such number of fully paid and nonassessable shares of Preferred Stock as is computed using the following formula: 
 X = Y(A-B) 
         A 
  

			
	where: X =	  	the number of shares of Preferred Stock to be issued to the Holder pursuant to this Section 4.
		
	Y =	  	the number of shares of Preferred Stock covered by this Warrant in respect of which the net issue election is made pursuant to this Section 4.
		
	A =	  	the Fair Market Value (defined below) of one share of Preferred Stock, as determined at the time the net issue election is made pursuant to this Section 4.
		
	B =	  	the Purchase Price in effect under this Warrant at the time the net issue election is made pursuant to this Section 4.










 “Fair Market Value” of a share of Preferred Stock (or fully paid and nonassessable
shares of the Company’s common stock, $0.001 par value (the “Common Stock”) if the Preferred Stock has been automatically converted into Common Stock) as of the date that the net issue election is made (the
“Determination Date”) shall mean: 
 (i) If the net issue election is made in connection with and
contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering pursuant to a Registration Statement under the 1933 Act (a “Public Offering”), and if the Company’s Registration
Statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect
to such offering multiplied by the number of shares of Common Stock into which each share of Preferred Stock is then convertible. 
 (ii) If the net issue election is not made in connection with and contingent upon a Public Offering, then as follows: 
 (a) If traded on a securities exchange or the Nasdaq National Market, the fair market value of the Common Stock shall be deemed to be the average of the closing or last reported sale prices of the Common Stock
on such exchange or market over the five day period ending five trading days prior to the Determination Date, and the fair market value of the Preferred Stock shall be deemed to be such fair market value of the Common Stock multiplied by the number
of shares of Common Stock into which each share of Preferred Stock is then convertible; 
 (b) If otherwise traded in
an over-the-counter market, the fair market value of the Common Stock shall be deemed to be the average of the closing ask prices of the Common Stock over the five day period ending five trading days prior to the Determination Date, and the fair
market value of the Preferred Stock shall be deemed to be such fair market value of the Common Stock multiplied by the number of shares of Common Stock into which each share of Preferred Stock is then convertible; and 
 (c) If there is no public market for the Common Stock, then fair market value shall be determined in good faith by the
Company’s Board of Directors. 
 5. Partial Exercise. This Warrant may be exercised in part, and the Holder shall be
entitled to receive a new warrant, which shall be dated as of the date of this Warrant, covering the number of shares in respect of which this Warrant shall not have been exercised. 
 6. Fractional Shares. In no event shall any fractional share of Preferred Stock be issued upon any exercise of this Warrant. If, upon
exercise of this Warrant in its entirety, the Holder would, except as provided in this Section 6, be entitled to receive a fractional share of Preferred Stock, then the Company shall issue the next higher number of full shares of
Preferred Stock, issuing a full share with respect to such fractional share. 
 7. Expiration Date; Automatic Exercise. This
Warrant shall expire at the close of business on __________, 2012, and shall be void thereafter (the “Expiration Date”). Notwithstanding the foregoing, this Warrant shall automatically be deemed to be exercised in full pursuant to
the provisions of Section 4 hereof, without any further action on behalf of the Holder, immediately prior to the time this Warrant would otherwise expire pursuant to the preceding sentence. 
  

 -2- 








 8. Reserved Shares; Valid Issuance. The Company covenants that it will at all times from
and after the date hereof reserve and keep available such number of its authorized shares of Preferred Stock and Common Stock free from all preemptive or similar rights therein, as will be sufficient to permit, respectively, the exercise of this
Warrant in full and the conversion into shares of Common Stock of all shares of Preferred Stock receivable upon such exercise. The Company further covenants that such shares as may be issued pursuant to such exercise and/or conversion will, upon
issuance, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof. 
 9. Stock Splits and Dividends. If after the date hereof the Company shall subdivide the Preferred Stock, by split-up or otherwise, or combine the Preferred Stock, or issue additional shares of Preferred Stock in payment of a
stock dividend on the Preferred Stock, the number of shares of Preferred Stock issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the
case of a combination, and the Purchase Price shall forthwith be proportionately decreased in the case of a subdivision or stock dividend, or proportionately increased in the case of a combination. 
 10. Adjustments for Diluting Issuances. The other antidilution rights applicable to the Preferred Stock and the Common Stock of the Company
are set forth in the Amended and Restated Certificate of Incorporation, as amended from time to time (the “Articles”), a true and complete copy in its current form which is attached hereto as Exhibit A. Such
rights shall not be restated, amended or modified in any manner which affects the Holder differently than the holders of Series C-l Preferred without such Holder’s prior written consent. The Company shall promptly provide the Holder hereof
with any restatement, amendment or modification to the Articles promptly after the same has been made. 
 11. Mergers and
Reclassifications. If after the date hereof the Company shall enter into any Reorganization (as hereinafter defined), this Warrant shall expire and terminate effective as of the closing of such Reorganization. Notwithstanding the foregoing, in
the event that any outstanding warrants to purchase equity securities of the Company are assumed by the successor entity of a Merger (or parent thereof), this Warrant shall also be similarly assumed. Notwithstanding the foregoing, this Warrant shall
automatically be deemed to be exercised in full pursuant to the provisions of Section 4 hereof, without any further action on behalf of the Holder, immediately prior to the time this Warrant would otherwise expire pursuant to the
preceding sentence. For the purposes of this Section 11, the term “Reorganization” shall include without limitation any reclassification, capital reorganization or change of the Preferred Stock (other than as a result of
a subdivision, combination or stock dividend provided for in Section 9 hereof), or any consolidation of the Company with, or merger of the Company into, another corporation or other business organization (other than a merger in which the
Company is the surviving corporation and which does not result in any reclassification or change of the outstanding Preferred Stock), or any sale or conveyance to another corporation or other business organization of all or substantially all of the
assets of the Company. 
 12. Certificate of Adjustment. Whenever the Purchase Price is adjusted, as herein provided, the
Company shall promptly deliver to the Holder a certificate of the Company’s chief financial officer setting forth the Purchase Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 

13. Notices of Record Date, Etc. In the event of: 
 (a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders
thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase, sell or otherwise acquire or dispose of any shares of stock of any class or any other securities or property, or to receive any other
right; 
 (b) any reclassification of the capital stock of the Company, capital reorganization of the Company,
consolidation or merger involving the Company (other than a merger in which the Company is the surviving corporation and which does not result in any reclassification or change of the outstanding Preferred Stock), or sale or conveyance of all or
substantially all of its assets; or 
  

 -3- 








 (c) any voluntary or involuntary dissolution, liquidation or winding-up of the
Company; then in each such event the Company will provide or cause to be provided to the Holder a written notice thereof. Such notice shall be provided at least twenty (20) business days prior to the date specified in such notice on which any
such action is to be taken.

 (i) If the net issue election is made in connection with and
contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering pursuant to a Registration Statement under the 1933 Act (a “Public Offering”), and if the Company’s Registration
Statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect
to such offering multiplied by the number of shares of Common Stock into which each share of Preferred Stock is then convertible. 
 (ii) If the net issue election is not made in connection with and contingent upon a Public Offering, then as follows: 
 (a) If traded on a securities exchange or the Nasdaq National Market, the fair market value of the Common Stock shall be deemed to be the average of the closing or last reported sale prices of the Common Stock
on such exchange or market over the five day period ending five trading days prior to the Determination Date, and the fair market value of the Preferred Stock shall be deemed to be such fair market value of the Common Stock multiplied by the number
of shares of Common Stock into which each share of Preferred Stock is then convertible; 
 (b) If otherwise traded in
an over-the-counter market, the fair market value of the Common Stock shall be deemed to be the average of the closing ask prices of the Common Stock over the five day period ending five trading days prior to the Determination Date, and the fair
market value of the Preferred Stock shall be deemed to be such fair market value of the Common Stock multiplied by the number of shares of Common Stock into which each share of Preferred Stock is then convertible; and 
 (c) If there is no public market for the Common Stock, then fair market value shall be determined in good faith by the
Company’s Board of Directors. 
 5. Partial Exercise. This Warrant may be exercised in part, and the Holder shall be
entitled to receive a new warrant, which shall be dated as of the date of this Warrant, covering the number of shares in respect of which this Warrant shall not have been exercised. 
 6. Fractional Shares. In no event shall any fractional share of Preferred Stock be issued upon any exercise of this Warrant. If, upon
exercise of this Warrant in its entirety, the Holder would, except as provided in this Section 6, be entitled to receive a fractional share of Preferred Stock, then the Company shall issue the next higher number of full shares of
Preferred Stock, issuing a full share with respect to such fractional share. 
 7. Expiration Date; Automatic Exercise. This
Warrant shall expire at the close of business on __________, 2012, and shall be void thereafter (the “Expiration Date”). Notwithstanding the foregoing, this Warrant shall automatically be deemed to be exercised in full pursuant to
the provisions of Section 4 hereof, without any further action on behalf of the Holder, immediately prior to the time this Warrant would otherwise expire pursuant to the preceding sentence.

 8. Reserved Shares; Valid Issuance. The Company covenants that it will at all times from
and after the date hereof reserve and keep available such number of its authorized shares of Preferred Stock and Common Stock free from all preemptive or similar rights therein, as will be sufficient to permit, respectively, the exercise of this
Warrant in full and the conversion into shares of Common Stock of all shares of Preferred Stock receivable upon such exercise. The Company further covenants that such shares as may be issued pursuant to such exercise and/or conversion will, upon
issuance, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof. 
 9. Stock Splits and Dividends. If after the date hereof the Company shall subdivide the Preferred Stock, by split-up or otherwise, or combine the Preferred Stock, or issue additional shares of Preferred Stock in payment of a
stock dividend on the Preferred Stock, the number of shares of Preferred Stock issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the
case of a combination, and the Purchase Price shall forthwith be proportionately decreased in the case of a subdivision or stock dividend, or proportionately increased in the case of a combination. 
 10. Adjustments for Diluting Issuances. The other antidilution rights applicable to the Preferred Stock and the Common Stock of the Company
are set forth in the Amended and Restated Certificate of Incorporation, as amended from time to time (the “Articles”), a true and complete copy in its current form which is attached hereto as Exhibit A. Such
rights shall not be restated, amended or modified in any manner which affects the Holder differently than the holders of Series C-l Preferred without such Holder’s prior written consent. The Company shall promptly provide the Holder hereof
with any restatement, amendment or modification to the Articles promptly after the same has been made. 
 11. Mergers and
Reclassifications. If after the date hereof the Company shall enter into any Reorganization (as hereinafter defined), this Warrant shall expire and terminate effective as of the closing of such Reorganization. Notwithstanding the foregoing, in
the event that any outstanding warrants to purchase equity securities of the Company are assumed by the successor entity of a Merger (or parent thereof), this Warrant shall also be similarly assumed. Notwithstanding the foregoing, this Warrant shall
automatically be deemed to be exercised in full pursuant to the provisions of Section 4 hereof, without any further action on behalf of the Holder, immediately prior to the time this Warrant would otherwise expire pursuant to the
preceding sentence. For the purposes of this Section 11, the term “Reorganization” shall include without limitation any reclassification, capital reorganization or change of the Preferred Stock (other than as a result of
a subdivision, combination or stock dividend provided for in Section 9 hereof), or any consolidation of the Company with, or merger of the Company into, another corporation or other business organization (other than a merger in which the
Company is the surviving corporation and which does not result in any reclassification or change of the outstanding Preferred Stock), or any sale or conveyance to another corporation or other business organization of all or substantially all of the
assets of the Company. 
 12. Certificate of Adjustment. Whenever the Purchase Price is adjusted, as herein provided, the Company
shall promptly deliver to the Holder a certificate of the Company’s chief financial officer setting forth the Purchase Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 
 13. Notices of Record Date, Etc. In the event of: 
 (a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders
thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase, sell or otherwise acquire or dispose of any shares of stock of any class or any other securities or property, or to receive any other
right; 
 (b) any reclassification of the capital stock of the Company, capital reorganization of the Company,
consolidation or merger involving the Company (other than a merger in which the Company is the surviving corporation and which does not result in any reclassification or change of the outstanding Preferred Stock), or sale or conveyance of all or
substantially all of its assets; or 
  

 -3- 








 (c) any voluntary or involuntary dissolution, liquidation or winding-up of the
Company; then in each such event the Company will provide or cause to be provided to the Holder a written notice thereof. Such notice shall be provided at least twenty (20) business days prior to the date specified in such notice on which any
such action is to be taken.

order to protect the rights of the Holder. 
 20. Governing Law. The provisions and terms of this Warrant shall be governed by
