MASTER NETTING, SETOFF, CREDIT AND SECURITY AGREEMENT WASHINGTON, IA

Producer and Gavilon are Parties to a certain Feedstock Supply Agreement (“Feedstock Agreement”) and a certain Biodiesel Sale and Purchase Agreement (“Biodiesel Agreement”), each of even date herewith (collectively, the “Supply Agreements”).

The Supply Agreements require each Party to make payment to, and to perform various supply and other obligations for, the other Party.

Each Party desires to have the right to setoff, net and terminate the transactions under the Supply Agreements in accordance with the terms thereof and hereof, and this Master Agreement is entered into in reliance on the Parties' agreements herein.

The Parties further desire to set forth and establish certain credit and security obligations required in connection with the Supply Agreements.

Due Dates; Payment Dates. Payments for Feedstock shall be deemed due from Producer on the fifteenth (15^th) day after delivery to Producer's plant. Payments for Biodiesel shall be deemed due from Gavilon on the day of delivery into Gavilon's transport vessel. Any amounts owed by the Parties pursuant to the Supply Agreements and which are deemed due during each week (Monday through Sunday) shall be payable on the following Wednesday (each a “Payment Date”). If any Payment Date falls on a Holiday, payment shall be made on the preceding banking day.”

Netting Statements. Each Monday Gavilon shall provide Producer with a netting statement which identifies the Parties' respective payment obligations under the Supply Agreements during the prior week (the “Netting Statement”), and the difference of the greater amount owed by either Party less the amount owed by the other Party (the “Net Settlement”). The Net Settlement shall be paid by the Party owing the greater amount. Payment shall be made via wire transfer to the other Party on the applicable Payment Date. The Applicable Payment Date for finished biodiesel shall be as described in Item 1.1 as above.

Disputed Amounts. Producer shall promptly notify Gavilon of any disputes it may have upon the receipt of each Netting Statement. If any portion of the Net Settlement remains subject to dispute as of an applicable Payment Date, the disputed amount shall nonetheless be paid and then resolved pursuant to the terms of the applicable Supply Agreement and this Agreement. Any refund or additional amounts owed by either Party to the other Party shall be promptly paid upon resolution of the dispute.

Representations, Warranties and Covenants. Each of Producer and Gavilon represents, warrants and covenants to the other that:

It is not relying upon any representations of the other Party other than those expressly set forth in this Master Agreement, the Supply Agreements or any confirmation issued pursuant thereto;

It has entered into this Master Agreement with a full understanding of the material terms and risks of the same, and it is capable of assuming those risks;

The Parties agree that this Master Agreement, the Supply Agreements, and the transactions thereunder form a single integrated agreement. Each Party has received consideration hereunder for its agreement to treat each of the Supply Agreements and this Master Agreement as one integrated agreement; and

Except as set forth in Section 4.2, or pursuant to the Consent to Collateral Assignment of Contracts and Agreements and Intercreditor Agreement dated October 12, 2011 between Gavilon and MLIC Asset Holdings, LLC (the “Consent Agreement”), it has not assigned, transferred, created or permitted to exist any lien or other encumbrance on, or otherwise disposed of, or purported to assign, transfer, create or permit to exist any lien or other encumbrance on, or otherwise dispose of, any of its rights to any amounts that may be owed to it under the Supply Agreements to any third party, and covenants that, so long as this Master Agreement is in effect, it will not assign, transfer, create or permit to exist any lien or other encumbrance on, or otherwise dispose of or purport to assign, transfer, create or permit to exist any lien or other encumbrance on, or otherwise dispose of, any of its rights to any amounts that may be owed to it under the Supply Agreements, to any third party.

Additional Security. Producer hereby grants to Gavilon a first priority continuing security interest in all right, title and interest held by Producer in, to and under all transactions (subject to clause 4.2(a)) arising under the Supply Agreements including payment intangibles and other contract rights, receivables and other proceeds arising therefrom. By executing this Master Agreement Producer authorizes Gavilon to file such financing statements and notices as Gavilon deems appropriate to perfect such security interest. It is understood that the transactions entered into under the Supply Agreements are based on and subject to, market volatility and other factors as well as Producer's credit standing. Consequently, such factors may necessitate that Producer provide security in an amount determined by Gavilon in its reasonable discretion or otherwise provide adequate assurances of Producer's ability to perform all of its obligations under the Supply Agreements. Gavilon acknowledges that additional security may be limited by Producer's existing creditors and may require such creditors' prior approval.

Financial Information. If requested by Gavilon, Producer shall deliver within one hundred twenty (120) days following the end of each fiscal year, a copy of its (or its guarantor's) annual report containing audited consolidated financial statements for such fiscal year certified by independent certified public accountants. In all cases the statements shall be for the most recent accounting period and prepared in accordance with generally accepted accounting principles, consistently applied; provided, however, should any such statements not be available timely due to a delay in preparation or certification, such delay shall not be considered a default so long as Producer diligently pursues the preparation, certification and delivery of the statements.

Term. This Master Agreement shall commence on the date hereof and continue in effect until the Supply Agreements have been terminated and all amounts owing thereunder shall have been fully and indefeasibly paid.

Assignment. Except as set forth herein, neither Party may assign this Agreement or any of its rights or obligations hereunder without the prior written consent of the other Party. A change in fifty percent (50%) or more in the ownership of either Party shall be construed to be an assignment for purposes of this Section 4.2. The above notwithstanding, (a) Producer may assign its rights to receive any Net Settlement or Final Net Settlement Amount to a lender that first executes the Consent Agreement, and (b) Gavilon may, without the need for consent from Producer: (i) transfer, sell, pledge, encumber or assign this Agreement in connection with any financing or other financial arrangements; (ii) transfer or assign this Agreement to an affiliate as long as the affiliate is at least as creditworthy as Gavilon; or (iii) transfer or assign this Agreement to an entity succeeding to all or substantially all of the assets of Gavilon by way of merger, reorganization or otherwise. In the event the Plant is sold by Producer, Producer shall assign this Master Agreement to the purchaser of the Plant and require the purchaser to assume all of Producer's obligations hereunder, provided that such purchaser is reasonably acceptable to Gavilon. Except as provided in the Consent Agreement, no such assignment shall affect the rights or obligations of the Parties (including those with respect to netting and setoff) under this Agreement or any Confirmed Orders. It is further agreed that no such assignment shall be permitted unless the Supply Agreements are similarly assigned in accordance with their terms.
