  Niall Kelleher, Director of Finance, Amyris Biotechnologies, Inc. 

Ladies and Gentlemen: 
 The
purpose of this letter (this “Uncommitted Facility Letter”) is to outline the parameters of the uncommitted guidance facility available from BNP Paribas (the “Bank”) for Amyris Fuels, Inc., a corporation organized under the laws
of the State of Delaware (the “Obligor”), for the issuance of letters of credit (documentary and standby) (“Letters of Credit”) and the making of advances (“Advances”, each Letter of Credit or Advance, an
“Accommodation” and collectively, the “Accommodations”). 
 An “uncommitted guidance
facility” means that the Bank shall have no obligation to issue or grant any Accommodation. Each request made by the Obligor for an Accommodation shall be reviewed by the Bank on a case by case basis and the decision to grant any such
Accommodation shall be made by the Bank in its absolute and sole discretion and irrespective of whether or not the Obligor is in compliance with any of the guidelines set forth below. The Bank also reserves the right to summarily refuse any request
for an Accommodation without any review as contemplated by the preceding sentence. Accordingly, the Bank has no commitment to make any Accommodation available. 
  

			
	Obligor:	  	Amyris Fuels, Inc.
		
	Guarantor(s):	  	Amyris Biotechnologies, Inc.
		
	Type:	  	Uncommitted guidance facility (Secured; Borrowing Base)
		
	Purpose:	  	 To provide Accommodations to finance the Obligor’s purchase and sale of ethanol and such other products as the Bank may approve from time to time
(collectively “Product”) and for related hedging and working capital requirements related thereto and general working capital.

		
		  	 Advances may be used to finance negative cash flow, the carrying of accounts receivable, the purchase of Product and margin financing requirements. Letters of
Credit may be used to finance the purchase of Product for resale, for swap transactions related to the hedging of Product, to secure transportation and other performance related obligations of the Obligor.










			
	Availability and Maturity:	  	 No request for any Accommodation may be made after November 24, 2009 (the “Maturity Date”) unless the Bank, in its sole discretion and without
any obligation to do so, extends such date in writing. All Accommodations are payable on the earlier of any specified maturity thereof or ON DEMAND. Any issued and outstanding Letter of Credit with an expiry date later than the Maturity Date
must be cash collateralized in an amount equal to at least 105% of the face amount of such Letter of Credit, in form and substance satisfactory to the Bank, five business days prior to the Maturity Date and shall continue to be secured after the
Maturity Date by such cash and all other collateral in which the Bank has been granted a security interest by the Obligor.

		
		  	 The Obligor may repay any Advance at any time, and from time to time, without penalty or premium and any amount repaid may, subject to the terms hereof, be
reborrowed. Subject to those provisions that expressly provide for survival hereunder, the Obligor may terminate this Uncommitted Facility Letter at any time (without penalty or premium) upon the repayment of all the Advances, the termination of the
Letters of Credit and the repayment of all other amounts then due, owing or accrued hereunder or under any Security Document. Upon any such termination, the Security Documents shall terminate and the Bank shall execute such documents and take such
actions (at Obligor’s expense) as Obligor shall reasonably request to evidence such termination and the termination of liens in and, where applicable, reconveyance, of any collateral herefor.

		
	 Maximum
 Amount:

	  	 Up to the lower of (i) $35,000,000 (“Maximum Amount”) and (ii) the Borrowing Base as defined herein, without, for such purpose only, giving effect
to any outstanding Accommodations.

		
		  	 Included in the Maximum Amount are the following sublimits:

 
 Advance Sublimit: Up to
$20,000,000 for short-term Advances for Product purchases where payment for Product is required to be made prior to receipt of backing receivables associated with such Advance and for associated margin requirements.

		
		  	 Letters of Credit Sublimit: Up to $10,000,000 for Letters of Credit with a maximum tenor of more than 90 days and less than
364 days and performance Letters of Credit of any tenor up to a maximum tenor of less than 364 days.

		
		  	 Any Accommodation may be subject to various sublimits at the same time. A sublimit is an indication of the Bank’s present view of the maximum amount that
it might consider for particular types of Accommodations. Notwithstanding any such sublimits, the Bank has no commitment to make any Accommodation available. Accordingly, under no circumstances should the listing of the above sublimits, or the
incorporation by the Bank of additional sublimits from time to time, be construed as an agreement or commitment by the Bank to provide any


  

 2 









			
		  	 Accommodation within any such sublimit.
  

		  	 Please note that the Bank may modify the Maximum Amount, modify the Borrowing Base, modify or cancel any of the
existing sublimits or incorporate additional sublimits at any time at its sole discretion.

		  	 If on the date of delivery to the Bank of any such Borrowing Base Certificate (or if the Obligor fails to deliver the
same), the aggregate amount of Accommodations outstanding as of the relevant Borrowing Base Reporting Date (as defined above) exceed the Borrowing Base reported thereon (or, in the event of a failure to deliver the same, the Borrowing Base as then
determined by the Bank) the Obligor shall immediately prepay the Accommodations in an amount sufficient so that the Accommodations remaining outstanding do not exceed the Borrowing Base reported on such Borrowing Base Certificate, with such
prepayments being applied first to any outstanding Advances and then to cash collateralizing any outstanding Letters of Credit.

		  	 e)     Backing letters of credit to be advised to
the Bank, or at a minimum, the original letter of credit forwarded by Obligor to the Bank.

maintaining, monitoring and operating this uncommitted facility for the Obligor and expects to receive annual compensation from the facility in an amount at least equal to the Base Amount (as defined herein). In the event that, for any calendar year
(or portion thereof during which this uncommitted facility is in place and is either available to the Borrower to request Accommodations or Accommodations remain outstanding), Cumulative Compensation (as defined herein) earned and paid to the Bank
by the Obligor does not equal the Base Amount, then, in consideration for the Bank maintaining this uncommitted facility, the Obligor agrees to pay the Bank the Minimum Compensation Fee (as defined herein).

		
		  	 Accordingly, promptly following the end of each calendar year (or the date of any termination or expiration of the uncommitted facility hereunder), the Bank
and the Obligor shall calculate the amount of Cumulative Compensation received by the Bank from the Obligor from the beginning of the calendar year to the end of such calendar year (or the date of any termination or expiration of the uncommitted
facility hereunder). If the amount of Cumulative Compensation received by the Bank for the period in question is less than the Base Amount, the Obligor shall pay to the Bank a fee equal to the difference between such Cumulative Compensation and the
Base Amount (the amount of such difference being the “Minimum Compensation Fee”) within five days after calculation of the Cumulative Compensation.

		
		  	 The Obligor acknowledges that neither the payment of any Minimum Compensation Fee nor the Obligor’s obligation to do so shall require the Bank to
maintain the uncommitted facility or to agree to provide any, or any minimum number of, Accommodations to the Obligor.

		
		  	 As used herein, the following terms have the meanings set forth below.

		
		  	 “Base Amount” means $300,000 for the calendar year January to December (or a pro-rated portion of $300,000 corresponding to that portion of any
calendar year that the Bank’s uncommitted facility was in place).

		
		  	 “Cumulative Compensation” means the annual aggregate amount of compensation earned and paid to the Bank in a calendar year from this uncommitted
facility from Letter of Credit commissions, interest on Advances (calculated on the margin collected over the Bank’s Cost of Funds or the Bank’s Prime Rate with respect such Advances as determined by the Bank), Administrative Fee and
monthly wire transfer fees. Cumulative Compensation shall not include the Origination Fee or


  

 7 









			
		  	 the Documentation Fee, but shall include the monthly Administrative Fee. In the event of any difference between the Bank’s and the Obligor’s
calculations of Cumulative Compensation, the Bank’s calculation of Cumulative Compensation shall be conclusive absent manifest error.

		
	Calculation of Interest and Fees:	  	 All interest and fees shall be calculated on a year of 360 days and days actually elapsed.

		
	Security /Other Documentation:	  	 All Accommodations shall be fully secured by a first priority perfected security interest (subject to Permitted Liens) in all Obligor’s present and

		  	 In addition to the Security Documents, Obligor shall also deliver to the Bank, prior to the first Accommodation, the following documents and such other
documents as the Bank may reasonably request from time to time:

		
		  	 a)     Corporate Resolutions (including incumbency

Obligor acknowledges that all amounts due by the Obligor to CIT and/or CFI under such facilities will be secured by all “Collateral” under all of the Security Documents under this Uncommitted Facility Letter and the Obligor acknowledges
that all amounts due from CIT and/or CFI to the Obligor and all property of the Obligor held by CIT and/or CFI shall secure all the obligations of the Obligor to the Bank (including CIT) and to CFI. The Obligor acknowledges that unless otherwise
expressly agreed to in writing by CIT or CFI, as the case may be, none of such “Collateral” shall satisfy or be deemed to satisfy any obligation of the Obligor to CIT or CFI to provide margin or other payment or to deliver credit support,
posted collateral or similar security under the terms of any ISDA Master Agreement, Credit Support Annex or similar agreement between CIT and Obligor (collectively the “CIT ISDA Documents”) or any Customer Agreement or similar agreement
with CFI (collectively, “CFI Futures Documents”) except for cash or other property delivered by Obligor specifically in satisfaction of such obligation under the terms of the relevant CIT ISDA Documents or the CFI Futures Documents, as the
case may be. The Obligor further acknowledges that CFI (and for the avoidance of doubt, CIT) is entitled to benefit from the provisions of the preceding sentences, notwithstanding that it is not a party hereto.
