NOW, THEREFORE, in consideration of the mutual agreements specified in this Amendment, EdenIQ, the Stockholder Representative, and Aemetis hereby agree as follows:

1. Amendment to Section 4.1 of the Agreement.

(a) Section 4.1 of the Agreement is amended and restated in its entirety to read as follows:

 “4.1 Operation in Ordinary Course. EdenIQ covenants that between the date hereof and the Closing, except as contemplated hereby or with the prior consent of Aemetis, it shall refrain from: (a) entering into any transaction with respect to its business other than in the ordinary course; (b) permitting any encumbrance, mortgage, pledge or lease of or on any material asset, other than in connection with the conduct of EdenIQ’s business in the ordinary course; (c) disposing of any material asset; (d) incurring any material liabilities, other than indebtedness incurred in the ordinary course of business under already established credit facilities or in connection with the Transactions; (e) accelerating the collection of any receivables or delay the payment of liabilities outside the ordinary course; or (f) making any material product or marketing announcement; provided, however, that nothing in this Section 4.1 or any other term or provision of this Agreement shall prevent EdenIQ or its employees, officers, directors or Affiliates from directly or indirectly, soliciting, initiating, encouraging, discussing, negotiating or accepting any offer or proposal by or from any party regarding (A) any reorganization, recapitalization, or merger of EdenIQ; (B) any acquisition or disposition of an interest in any capital stock of EdenIQ or any securities convertible into any capital stock of EdenIQ; (C) any issuance by EdenIQ of any new indebtedness or refinancing of existing indebtedness; or (D) any similar transaction (collectively, an “Alternative Transaction”); provided further, that EdenIQ may not enter into any binding legal agreement with respect to any such Alternative Transaction prior to the termination of this Agreement. All EdenIQ records regarding such an Alternative Transaction shall be exempt from the provision of Section 4.2 and Aemetis shall not be entitled access to such materials.”

2. Amendment to Section 8.1(d) of the Agreement.

(a) Section 8.1(d) of the Agreement is amended and restated in its entirety to read as follows:

“(d) By either EdenIQ or Aemetis, upon written notice, if the transactions contemplated by this Agreement have not been consummated by July 22, 2016, (the “Termination Date”); provided that the right to terminate this Agreement under this Section 8.1(d) shall not be available to a Party if the failure of such transactions to be consummated is due to the willful failure of such Party to perform any of its obligations under this Agreement to the extent required to be performed by it prior to or on the Closing Date.”

3. Defined Terms. Capitalized terms used but not defined herein shall have the meaning assigned to them in the Agreement.

4. No Other Modification. The Agreement shall not be modified by this Amendment in any respect except as expressly set forth herein.

5. Governing Law. The validity, interpretation, and performance of this Agreement shall be controlled by and construed under the laws of the State of Delaware.
