RECITALS:

                                                A.                                   The Commission is charged with the management and operation of the Ports of Indiana, including the Port of Indiana-Mount Vernon, in Posey County, Indiana (the “Port”).

                                                B.                                     The Parties entered into a certain Lease Agreement dated October 31^st, 2006 wherein the Commission did lease to Lessee a tract of real estate consisting of approximately 116 acres, more or less, located at the Port to be used and occupied by Lessee only for the operation of an ethanol production facility, including the production, storage and shipment (by truck, railroad, barge, pipeline and other means of transportation) of ethanol and ethanol related product and by products, and for related offices, storage tanks, storage facilities and other facilities incidental to such activity (the “Lease”).

                                                C.                                     Lessee and the staff of the Commission each had substantial participation in the preparation of the Lease, which was executed by the Office of the Attorney General and the Office of the Governor on January 19, 2007 and January 24, 2007 respectively.

                                                D.                                    The Parties entered into a certain First Amendment to Lease Agreement and Reaffirmation of Guaranty dated June 14^th, 2007 wherein Section 3.04(b), 4.01(b), and 4.01(c) were deleted in their entirety and new Sections 3.04(b), 4.01(b) and 4.01(c) were replaced as stated in said First Amendment to Lease Agreement.

                                                E.                                      Section 4.01(b) of the First Amendment of Lease Agreement reads:

(b)                                 Lessee shall commence construction of Phase I of the Project on or before September 1, 2007 (the “Construction Date”).  For purposes hereof, “Commence Construction” means the presence of contractors on the Leased Premises performing excavation work beyond clearing of the site after Lessee has obtained all required building permits.  Lessee shall: (i) cause substantial completion of Phase One of the Project with a capacity of 110 million gallons of ethanol and the commencement of production of ethanol from Phase One (other than for the purposes of testing operations) to occur on or before March 1, 2009, and (ii) to cause substantial completion of Phase Two of the Project with a capacity of an additional 110 million gallons of ethanol and the commencement of production of ethanol from Phase Two (other than for purposes of testing operations) to occur on or before January 1, 2010.

F.                                      Section 4.01(c), in part, acknowledged the existence of external circumstances and conditions, which could arise, through no fault of Lessee, which would make it impossible for Lessee to comply with the defined Construction Date.  Section 4.01(c) further provides for a procedure wherein Lessee would notify the Commission of its anticipated failure to comply with the Construction Date, the extension of the Construction Date, and the Parties obligations should Lessee thereafter provide written notice to the Commission of its anticipated failure to comply with the extended Construction Date.  Further, Section 4.01(c) provides:  In the event Lessee believes it will be unable to obtain permits by July 1, 2007, but in good faith believes that such permits may be issued by September 1, 2007, Lessee may postpone until September 1, 2007 such July 1, 2007 date by written notice of such postponement provided to the Commission on or before July 1, 2007.

Lessee may thereafter, but prior to September 1, 2007, give the Commission written notice of an anticipated failure to comply with the September 1, 2007 date.  Immediately following the written notice, Lessee and the Commission agree to negotiate in good faith a waiver of the September 1, 2007 date and the establishment of a new date, which shall be for the shortest reasonable time period required.  Failing agreement, either Lessee or the Commission may terminate this Lease.

G.                                          Pursuant to Section 4.01 (c) Lessee provided written notice to the Commission by letter dated August 30, 2007 of its belifef it would be unable to obtain permits by September 1, 2007, thereby stating its belief it would be unable to commence construction by September 1, 2007.

H.                                         Section 4.01 (c) states: “Immediately following the written notice, Lessee and the Commission agree to negotiate in good faith a waiver of the September 1, 2007 date and the establishment of a new date, which shall be for the shortest reasonable time period required. Failing agreement, either Lessee or the Commission may terminate this Lease”.

I.                                              The Parties have negotiated in good faith a waiver of the September 1, 2007 date and the amendment of certain terms of the Lease and wish to herein memorialize their agreement.

J.                                             Guarantor is joining in the execution of this Second Amendment solely for purposes of consenting to all provisions of this Amendment and ratifying, confirming and reaffirming its obligations under that certain Lease Guaranty dated as of October 31, 2006 (the “Lease Guaranty”).

K.                    The Lessee, the Commission and Guarantor have each had substantial participation in the preparation of this Amendment which shall, upon approval by the Governor of Indiana, become effective.

L.                                      At a properly convened public meeting, the Commission has duly approved the execution and delivery of this Amendment by its duly authorized officers.
