LANDFILL GAS PURCHASE AND SALE AGREEMENT

This Landfill Gas Sale & Agreement (“Agreement”) dated July 28, 2006 is made between Siouxland Ethanol, a Nebraska corporation (“Buyer”) and ▇.▇. ▇▇▇▇, Inc. a Nebraska corporation (“Seller”).

WHEREAS, Seller owns and operates a private landfill (“Landfill”) at ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇; and

WHEREAS, the Landfill is producing certain gases resulting from the natural anaerobic decomposition of refuse material (“Landfill Gas”) and Seller desires to capture and dispose of the Landfill Gas in an environmentally and economically prudent fashion; and

WHEREAS, Buyer owns and operates an ethanol plant facility (the Facility) in Jackson, Nebraska which is located approximately one mile from the landfill; and

WHEREAS, Seller desires to sell and deliver the Landfill Gas produced at the Landfill to Buyer’s Facility and to construct facilities to extract, handle, and transport the Landfill Gas; and

WHEREAS, Buyer desires to purchase from Seller the Landfill Gas produced at the Landfill for use as fuel in one or more burners at the Facility.

NOW, THEREFORE, in consideration of the premises and the mutual promises hereinafter set forth, Seller agrees to sell and Buyer agrees to purchase Landfill Gas upon the terms and conditions set forth in this Agreement.

Article I – Definitions

Article II-Construction of Landfill Gas Equipment and Facilities

2.1 Pipeline, Equipment and Facilities

(a) Seller shall be solely responsible and liable for designing, constructing, operating, maintaining and repairing any and all equipment and facilities located on its property and used to extract, capture, handle, store and/or transport the Landfill Gas from the Landfill to the southern edge of Seller’s property and to the northern edge of Buyer’s property, located between ▇▇▇▇ Blvd. and 143^rd Street, Dakota County, Nebraska (“Seller’s Equipment”). Seller shall be fully and solely responsible and liable for operating, maintaining and repairing Seller’s Equipment, and shall be deemed the operator of such pipeline and equipment for purposes of the Nebraska One Call Law (Title 155, Chap. 2).

Such support shall include participating in regulatory proceedings and providing information concerning each party’s operations.
2.3		Equipment and systems for combustion of Landfill Gas. Seller agrees to reimburse the Buyer up to $400,000 for the design, installation and maintenance of specific equipment and systems required for the combustion of Landfill Gas in the Buyers’ ethanol plant. The Seller has until the end of the fifth year from the Commencement Date to pay the $400,000. Upon written request, the Buyer shall provide a detailed invoice to Seller for the equipment and systems costs associated with the combustion of Landfill Gas.

Article III- Sale and Purchase of Landfill Gas

3.1 Sale and Purchase; Quantity — Except as provided in section 3.2 below. Seller shall make available to Buyer for purchase all of the Landfill Gas that seller extracts from the Landfill. It is the mutual expectation of Seller and Buyer that the Landfill will generate, and Seller will make available to Buyer, those quantities of Landfill Gas as described in section 5.1(a) and in Exhibit A attached hereto and incorporated herein. Seller agrees to deliver and sell to Buyer and Buyer agrees to accept and purchase from Seller that quantity of Landfill Gas and available for use by Buyer for fuel in the burner(s) in Buyer’s Facility. Exceptions to above would be in cases of necessary shut down by the ethanol plant for necessary repairs and updates. It will be the Seller’s responsibility to deal with the landfill methane being created at that time to either flare the gas or shut down the system in accordance with Nebraska DEQ requirements.

3.2 Price. The price per MMBtu for a given month (1^st through month end) will be a discount of 25% from the price published in ▇▇▇▇▇’▇ monthly “Inside FERC’s Gas Market Report” for the Northern Natural Gas Co. Demarcation spot gas price for that month, except with a final maximum price (ceiling) of $6.00 per MMBtu and final minimum price (floor) of $4.75 per MMBtu for a subject month period. Siouxland Ethanol further agrees to purchase up to 1200 MMBtu/day at above prices. In such cases that the Seller may produce in excess of 1200 MMBtu/day, Seller then agrees to lower the price for any amount over and above the initial 1200 MMBtu/day to a fixed price of the lesser of $3.25 per MMBtu or the ▇▇▇▇▇’▇ monthly spot gas price referenced above should such published price be below $3.25.

3.3MMBTU Adjustment. The agreed pricing set forth In Section 3.2 above is based on assumed average daily methane content of the Landfill Gas of 50% and a measured BTU value of 9.05 BTU/cf/%Methane by Volume, equal to approximately 500 BTU/cf. (See Exhibit B) Seller’s Equipment shall include a meter for daily monitoring and recording of percent methane content of the Landfill Gas. On a daily basis, Seller will record the methane content of the Landfill Gas delivered to Buyer based on the readings from such

meter. The average monthly methane content of the Landfill Gas multiplied by 9.05 BTU/cf/%methane shall be used as the second component in the MMBTU formula set forth in Section 1.2 above in determining the number of MMBTU purchased during such month.

3.4 Invoices; Payment. Within (10) business days following the end of each month, Buyer will transmit to Seller the applicable Facility Meter readings for Landfill Gas delivered to Buyer during the preceding such month. Based on the flow readings from Buyer’s Facility Meter and the methane readings from Seller’s meter, the BTU values from the Seller’s gas chromatograph and the “Inside FERC’s Gas Market Report” monthly Northern Natural Gas Co. Demarcation pricing index, Seller shall prepare and send to Buyer within 10 business days following receipt of the data from Buyer an invoice which shall be accompanied by a report showing daily amounts for flow, methane and MMBTUs. Buyer shall remit payment to Seller within 10 business days following receipt of Seller’s invoices.

3.5 Errors in Billing. Should either party find at any time within one (1) year after the date of any invoice rendered by Seller that there has been an undercharge or an overcharge in the amount billed in the invoice, the party finding the error shall promptly notify the other party in writing. In the Case of an undercharge, Seller shall submit a statement for such undercharge, and Buyer, upon verifying the same, shall pay such an amount within thirty — (30) days after receipt of the statement but without interest. In the case of an overcharge, Seller shall refund the amount of the overcharge to Buyer within thirty — (30) days of notification by Buyer, but without interest.
