 CODEXIS, INC. 
 Effective as of February 12, 2004 
 Void after February 12, 2011 
 1. Issuance. This Common Stock Purchase
Warrant (the “Warrant”) is issued to
                                        
 by CODEXIS, 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              (the “Purchase
Price”),                      fully paid and nonassessable shares of Common Stock, $0.0001 par value, of the Company (the
“Common 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 Common 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 (a) in cash or by check, or (b) 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 Common 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 Common Stock as is computed using the following formula: 
  

 1 









									
		 	 X
	 	 =
	 	 Y (A-B)
	 	
		 	 	 	A	 	

  

					
	where:	 	X =	 	the number of shares of Common Stock to be issued to the Holder pursuant to this Section 4.
			
		 	Y =	 	the number of shares of Common 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 Common 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 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. 
 (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; 
 (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 
 (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 Common Stock be issued upon any exercise of this Warrant. If, upon exercise of this Warrant in its entirety, the

  

 2 








 
Holder would, except as provided in this Section 6, be entitled to receive a fractional share of Common Stock, then the Company shall pay cash equal to the product of such fraction
multiplied by the Common Stock’s fair market value (as determined by the Board of Directors) on the date of exercise. 
 7. Expiration Date; Automatic Exercise. This Warrant shall expire at the close of business on February 12, 2011, and shall be void thereafter. 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 Common Stock, free from all preemptive or similar rights therein, as will be sufficient to permit the exercise of this Warrant in full. The Company further covenants that such shares as may be issued
pursuant to such exercise will, upon issuance in accordance with the terms hereof, 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 Common Stock, by split-up or otherwise, or
combine the Common Stock, or issue additional shares of Common Stock in payment of a stock dividend on the Common Stock, the number of shares of Common 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. Antidilution Rights. The other antidilution rights applicable to 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 Common Stock 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. Dissolutions, Liquidations, Mergers or Changes in Control. 
 (a) Dissolution or Liquidation.
In the event of the proposed dissolution or liquidation of the Company, the Company shall notify the Holder as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, the
Warrant will terminate immediately prior to the consummation of such proposed action. 
 (b) Merger or Change in
Control. In the event of a merger of the Company with or into another corporation, or a Change in Control, the Warrant shall be assumed or an equivalent warrant substituted by the successor corporation or a parent or subsidiary of the

  

 3 








 
successor corporation. In the event that the successor corporation or parent or subsidiary of the successor corporation in a merger or Change in Control refuses to assume or substitute for the
Warrant, then the Company shall notify the Holder in accordance with the provisions of Section 13 hereof of the pending Change of Control and Holder may then elect to exercise the Warrant not less than three (3) days prior to the
effective date of the Change of Control. 
 (c) “Change in Control” means the occurrence of any of the
following events: 
 (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”)) becomes the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing fifty percent
(50%) or more of the total voting power represented by the Company’s then outstanding voting securities; or 
 (ii) The consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; or 
 (iii) The consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation. 
 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, or sale or conveyance of all or substantially all of its assets; or 
 (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 ten
(10) days prior to the date specified in such notice on which any such action is to be taken.
