Re: Amendment to Uncommitted Facility Letter 

Ladies and Gentlemen: 

We refer to the Uncommitted Facility Letter, dated as of November 25, 2008 (as amended, the “Uncommitted
Facility Letter”), between BNP Paribas (the “Bank”) and Amyris Fuels, Inc. (predecessor in interest to Amyris Fuels, LLC, the “Borrower”). Unless otherwise defined, capitalized terms used in this Amendment to Uncommitted
Facility Letter (this “Amendment”) have the meanings provided for in the Uncommitted Facility Letter. 

Each of the undersigned hereby agrees that, effective as of the date hereof, the Uncommitted Facility Letter shall be
amended as follows: 
 1. The section entitled “Availability and Maturity” of the Uncommitted Facility
Letter is hereby amended by deleting the term “November 24, 2009” in the first sentence and inserting in lieu thereof “January 14, 2011.” 

2. Clause 2 in the section entitled “Borrowing Base” of the Uncommitted Facility Letter is hereby amended and
restated in its entirety to read as follows: 
 “2. Unrealized Gains on Eligible Forward Contracts (adjusted for margin
collected/ paid and net of offsetting unrealized losses or payables) shall be limited to the lesser of [*] of the total net borrowing base asset value and [*] in the aggregate.” 

3. Clause 4 in the section entitled “Borrowing Base” of the Uncommitted Facility Letter is hereby amended and
restated in its entirety to read as follows: 
 “4. Unsold inventory will be limited to [*].” 

This Amendment is executed pursuant to the Uncommitted Facility Letter and shall be construed, administered and applied
in accordance with all of the terms and provisions of the Uncommitted Facility Letter. 
 This Amendment shall
be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.
