 6.         Conditions to
Effectiveness.    The effectiveness of this Amendment is subject to satisfaction of each of the following conditions:

shall constitute a part of the agreement of the parties hereto.

Law.        This Amendment has been made, executed and delivered in the State of California and will be governed and construed for all purposes in accordance with the laws of the State of California,

AND US; CLAIMS THAT ARISE OUT OF OR ARE IN ANY WAY CONNECTED TO THE RELATIONSHIP BETWEEN YOU AND US; AND ANY CLAIMS FOR DAMAGES, BREACH OF CONTRACT, SPECIFIC PERFORMANCE OR ANY EQUITABLE OR LEGAL RELIEF OF ANY KIND, ARISING OUT OF THIS AGREEMENT.

executed in any number of counterparts, each of which will be deemed an original, but all such counterparts together constitute one and the same instrument. This Amendment may be executed and delivered by facsimile or transmitted electronically in
either Tagged Image Format Files (“TIFF”) or Portable Document Format (“PDF”) and, upon such delivery, the facsimile, TIFF or PDF signature, as applicable, will be deemed to have the same effect as if the original
signature had been delivered to the other party.

to each of Agri-Energy and Gevo under this Amendment, each of Agri-Energy and Gevo hereby agrees as follows: 

(a)        Agri-Energy and Gevo, for themselves and on behalf of their respective
successors and assigns, do hereby release, acquit and forever discharge TriplePoint, and the past or present officers, directors, attorneys, affiliates, employees and agents of 

  
 7 

 
TriplePoint, and each of their respective successors and assigns, from any and all claims, demands, obligations, liabilities, causes of action, offsets, damages, costs or expenses, of every type,
kind or nature, whether known or unknown, suspected or unsuspected, liquidated or unliquidated, including any claims that Agri-Energy, Gevo and their respective successors, counsel and advisors may in the future discover they would have now had if
they had known facts not now known to them, whether founded in contract, in tort or pursuant to any other theory of liability, that Agri-Energy or Gevo now has or may acquire against any one or more of them, arising out of events or transactions
which occurred on or before the date hereof (each a “Released Claim” and collectively, the “Released Claims”), including without limitation, those Released Claims arising out of or connected with the transactions

extent it may waive such rights and benefits. Section 1542 provides: 
 A GENERAL RELEASE DOES NOT
EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR. 

(c)        The provisions, waivers and releases set forth in this Section are binding
upon Agri-Energy, Gevo and their respective assigns and successors in interest. The provisions, waivers and releases of this Section shall inure to the benefit of TriplePoint and its agents, employees, officers, directors, assigns and successors in
interest. Agri-Energy and Gevo warrant and represent that they are the sole and lawful owner of all right, title and interest in and to all of the claims released hereby and they have not heretofore voluntarily, by operation of law or otherwise,
assigned or transferred or purported to assign or transfer to any person any such claim or any portion thereof. Each of Agri-Energy and Gevo shall indemnify and hold harmless TriplePoint from and against any claim, demand, damage, debt and liability
(including payment of attorneys’ fees and costs actually incurred whether or not litigation is commenced) based on or arising out of any such assignment or transfer. The provisions of this section shall survive the date hereof. Nothing herein
is or should be construed to be a release of claims against Agri-Energy or Gevo or a satisfaction of any indebtedness.
