ASSIGNMENT OF CONTRACT FOR CONSTRUCTION

This ASSIGNMENT OF CONTRACT FOR CONSTRUCTION (the “Assignment”) is made this 30^th day of March, 2007, by OTTER TAIL AG ENTERPRISES, LLC, a Minnesota limited liability company (the “Company”) in favor of MMCDC NEW MARKETS FUND II, LLC, a Delaware limited liability company (the “Lender”).

RECITALS

A. Company and Lender have entered into a Construction and Term Loan Agreement dated as of March 30, 2007 (as amended, restated or otherwise modified from time to time, the “Loan Agreement”), pursuant to which Lender will make certain loans to Company for the purposes of acquiring, constructing, equipping, and furnishing an ethanol production facility to be located near the City of Fergus Falls, Otter Tail County, Minnesota (the “Project”).

B. As a condition to extending the loans to Company, Lender has required the execution of this Assignment by Company.

AGREEMENT

Accordingly, in consideration of the foregoing, the parties agree as follows:

1. Company does hereby grant, assign, transfer and set over unto the Lender all of its right, title and interest in and to that certain Contract for Construction dated October 24, 2006 (the “Contract”) by and between Company and Xxxxx Bros. Construction, Inc., a Minnesota corporation, doing business as Xxxxx Brothers Companies, with a registered address of Xxxx 0^xx Xxxxxx & Xxxxxxx 00 Xxxxxx, Xxxxxx, Xxxxxxxxx 00000 (“Contractor”), providing for certain grading, streets, sewer and utility work and other services necessary to complete the work described in the Contract, a true and correct copy of which is attached to this Assignment as Exhibit A.

2. Company agrees that Lender does not assume any of the obligations or duties of Company under and with respect to the Contract unless and until Lender gives Contractor and Company written notice that it has affirmatively exercised its right to performance under the Contract following the occurrence of an Event of Default under the Loan Agreement, which has not been cured within the applicable grace period, if any. In the event that Lender does not personally undertake to complete the Project or perform under the Contract, Lender has no liability whatsoever for the performance of any such obligations or duties. For the purpose of performing under the Contract, Lender may, in its absolute discretion, reassign its right, title and interest in the Contract, upon notice to Contractor and the Company, but without any requirement of Company’s consent.

3. Company represents and warrants there have been no prior assignments of the Contract, that the Contract is a valid and enforceable agreement, and that neither Company nor Contractor is in default thereunder and that all covenants, conditions and agreements have been performed as required therein, except those not due to be performed until after the date hereof.

Except as permitted by the Loan Agreement, Company agrees that no material change in the terms thereof shall be valid without the prior written approval of Lender, which approval shall not be unreasonably withheld. Company agrees not to assign, sell, pledge, mortgage or otherwise transfer or encumber its interest in the Contract so long as this Assignment is in effect, except as otherwise permitted under the Loan Agreement.

4. Company hereby irrevocably constitutes and appoints Lender as its attorney-in-fact to demand, receive and enforce Company’s rights with respect to the Contract, to make payments under the Contract and to give appropriate receipt, releases and satisfactions for and on behalf of and in the name of Company, at the option of Lender in the name of Lender, with the same force and effect as Company could do if this Assignment had not been made.

5. This Assignment shall constitute a perfected, absolute and present assignment, provided that Lender shall have no right under this Assignment to take any actions under paragraph 4 of this Assignment or to enforce the provisions of this Assignment or the Contract until an Event of Default occurs under the Loan Agreement, which has not been cured within the applicable grace period, if any. Upon the occurrence of any such Event of Default, Lender may, without affecting any of its rights or remedies against Company under any other instrument, document, or agreement exercise its rights under this Assignment as Company’s attorney-in-fact in any manner permitted by law.

6. Company hereby agrees to indemnify and hold Lender harmless from and against any and all claims, demands, liabilities, losses, lawsuits, judgments, and reasonable costs and expenses, including without limitation reasonable attorneys’ fees, to which Lender may become exposed, or which Lender may incur, in exercising any of its rights under this Assignment.

7. Upon the repayment in full of all obligations due Lender by Company under the Loan Agreement, the assignment granted herein shall terminate and all rights, title and interest in and to the Contract shall revert back to Company. Upon any such termination, Lender will, at the expense of Company, execute and deliver to Company such documents as Company shall reasonably request to evidence the termination of the assignment.

8. Subject to the aforesaid limitation of further assignment by Company, this Assignment shall be binding upon Company, its successors and assigns, and shall inure to the benefit of Lender, its successors and assigns.

9. This Assignment can be waived, modified, amended, terminated or discharged only explicitly in writing signed by Lender and Company. A waiver signed by Lender shall be effective only in a specific instance and for the specific purpose given. Mere delay or failure to act shall not preclude the exercise or enforcement of any of Lender’s rights or remedies hereunder. All rights and remedies of Lender shall be cumulative and shall be exercised singularly or concurrently, at Lender’s option, and the exercise or enforcement of any one such right or remedy shall neither be a condition to nor bar the exercise of enforcement of any other.

10. The Company agrees that the Lender may, without the consent of the Company, assign its right, title and interest in the Contract to any Persons succeeding to Lender’s interest

(or any part thereof) under the Loan Agreement and any other Loan Documents, upon written notice to the Company, and any such assignment shall be valid and binding upon the Company. Nothing in this paragraph 10 shall modify any obligation of the Lender to provide notice to the Contractor or obtain the consent of the Contractor to an assignment of such interest as provided in the Contract.

11. All capitalized terms used in this Assignment, but not otherwise defined herein, shall have the meanings as set forth in the Loan Agreement.
