12. Commitments and Contingencies The LLC, through its subsidiaries, entered into two operating lease agreements with Cargill. Cargill s grain handling and storage facilities, located adjacent to the Wood River and Fairmont plants, are being leased for 20 years, which began in September 2008 for both plants. Minimum annual payments initially were $800,000 for the Fairmont plant and $1,000,000 for the Wood River plant so long as the associated corn supply agreements with Cargill remain in effect.

The deferred lease payments were to be paid back to Cargill over a two year period beginning September 1, 2010. On September 23, 2010 the subsidiaries and Cargill entered into a letter agreement ( Letter Agreement ) whereby (i) effective October 2010 the minimum annual payments under the leases were reduced to $50,000 for the Fairmont plant and $250,000 for the Wood River plant and (ii) repayment of the deferred lease payments have been deferred for an indefinite period of time. As of September 30, 2011 the deferred lease payments totaled $1.6 million and are included in other non-current liabilities.
