      NOW,
THEREFORE, in consideration of the foregoing premises, the mutual undertakings
hereinafter set forth, and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the Ports, Lessee and
Guarantor (solely for purposes of its agreement to the provisions of Paragraphs
3 and 4 below) hereby agree as follows:

       

      1.           The
Parties previously entered into a Fourth Amendment to Lease Agreement and
Reaffirmation of Guaranty dated June 19, 2008.  In part the Fourth
Amendment added the following language:

       

      5
(a)           Note to
east portion of Parcel #1 concerning additional railroad tracts to be installed
by the Commission to serve Consolidated Grain and Barge, to the effect that:
“Additional railroad tracks to be installed by the Indiana Port Commission, land
to be surrendered back to the Commission and deleted from the Leased Premises by
an amendment to the Lease between the Commission and Aventine Renewable
Energy-Mt Vernon, LLC.”

       

      2.           The
Parties agreed in Section 5 of the Fourth Amendment to enter into amendments to
the Lease to reflect as-built and other conditions of the Real
Estate.  In reference to Section 5(a) of the Fourth Amendment as
recited in Paragraph 1 of this Sixth Amendment, certain acreage of the Real
Estate will be removed from the Leased Premises and surrendered back to the
Ports. The land to be surrendered back to the Ports, defined herein as Tract 1,
consists of approximately 2.37 +/- acres
and is more particularly described and depicted in the drawing and
description attached hereto, made a part hereof, and marked as Exhibit 1
SBH-50009020512190.  A metes and bounds description, as well as
the actual acreage of Tract 1, will be established by the “as built” ALTA/ACSM
Land Title Survey of the Leased Premises, containing Table A Items 1-4, 6, 7a,
8-10, 11a and 13 (the "As
Built Survey") to
be provided by Lessee pursuant to paragraph 4 hereafter.

       

      3.           Attached
to said Fourth Amendment, as well as to this Sixth Amendment, is Exhibit A – Description of Leased
Real Estate, (“Exhibit
A”).  Exhibit A describes the Leased Premises as consisting of
118.05 acres.

       

      4.           By
agreement of the Parties a final As Built Survey is to be performed by Lessee
when the project is at a stage when the actual boundaries are readily
identifiable, including all necessary easements and rights of way, but in no
event later than December 31, 2009.

       

      5.           Article
III of the Lease provides that Lessee shall pay Initial Ground Rent of Three
Thousand Two Hundred Dollars ($3,200) per acre per year, and Section 1.01 of the
Lease identifies the demised real estate as approximately 116 acres, more or
less.

       

      6.           It
is further agreed by the Parties that an adjustment to the Initial Ground Rent
paid and payable by Lessee will be made upon completion of the As Built
Survey.  The Parties acknowledge that since the execution of the
Lease, Lessee has occupied more than the 116 acres.  Specifically,
Lessee has occupied 117.808 acres from October 31, 2006 until increased to
118.05 on June 19, 2008; and reduced by 2.37 acres on February 12, 2009. Until
the As Built Survey is 

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

      completed
and the adjustment to the Initial Ground Rent is calculated, the Initial Ground
Rent shall continue to be based upon the 116 acres.  Upon completion
of the As Built Survey, the Ports will calculate the actual Initial Ground Rent
that should have been paid since October 31, 2006 based upon the actual acreage
occupied by Lessee as such acreage has changed as set forth above (the "True Up Rent").  The
Initial Ground Rent that has been paid based upon the 116 acres shall be
subtracted from the True Up Rent and the difference, if any, shall be paid
by Lessee within 30 days of receipt of the invoice from the Ports.  In
the event that the result of the True Up Rent comparison is a negative amount,
such that Lessee has overpaid based on actual acreage occupied, then the Port
shall issue a credit to Lessee on the next month’s rent due.

      

      7.           Lessee
hereby releases and surrenders back to the Ports Tract 1, and the Ports hereby
accept Tract 1 and the same is hereby removed and deleted from the Demised
Premises.

       

      8.           Guarantor
hereby consents to the amendments to the Lease made by this Sixth Amendment and
agrees that such amendments shall not affect, impair, discharge, relieve or
release Guarantor of its obligations under the terms of the Lease Guaranty, and
that such Lease Guaranty shall be deemed to reference the Lease as amended
hereby.  Guarantor hereby ratifies, confirms and reaffirms in all
respects, the Lease Guaranty, and agrees that said Lease Guaranty shall continue
in full force and effect.

       

      9.           The
Ports and Lessee agree that the above and foregoing Recitals are true, correct
and complete and are hereby incorporated and made a part of this Sixth Amendment
as if completely and fully set forth herein.  Capitalized terms used
in this Sixth Amendment without definition shall have the meanings set forth in
the Lease as previously amended, except that any internal references in the
Lease to the word "Lease" shall mean the Lease,
as previously and hereby amended, wherever therein the context so requires in
order to give meaning to this Sixth Amendment.

       

      10.           Lessee
and the Ports hereby affirm, reaffirm and confirm that as of the date hereof the
Lease is in full force and effect, that the Lease has not been modified or
amended (except as provided in this Sixth Amendment) and that all of the Ports'
and Lessee's obligations accrued to date have been performed.  Lessee
and Ports hereby agree that there are, as of the date hereof, regardless of the
giving of notice or the passage of time, or both, no defaults or breaches on the
part of the Ports or Lessee under the Lease, as amended by this Sixth
Amendment.  Each of Lessee and the Ports hereby ratify the provisions
of the Lease on behalf of themselves and their respective successors and assigns
and agree to attorn and be bound to each other and their respective successors
and assigns as to all of the terms, covenants and conditions of the Lease, as
amended hereby.  This Sixth Amendment shall be incorporated into and
made a part of the Lease and all provisions thereof not expressly modified or
amended hereby shall remain in full force and effect.  Nothing
contained in this Sixth Amendment (except, as applicable, for the specific
amendments to the Lease set forth in this Sixth Amendment) shall release or
relieve Lessee or Ports from their respective obligations or liabilities under
the Lease accruing prior to the date hereof.

       

      11.           Except
as expressly amended and modified by this Sixth Amendment, the Lease shall
otherwise remain in full force and effect, the parties hereto hereby ratifying
and confirming

      the
same.  This Sixth Amendment, together with the Lease, is the complete
understanding between the parties and supersedes all other prior agreements and
representations concerning its subject matter.  To the extent of any
inconsistency between the Lease and this Sixth Amendment, the terms of this
Sixth Amendment shall control.

       

      12.           Immediately
following the signature page of this Sixth Amendment is the Addendum of State
required contract provisions previously executed by the Parties.  The
Parties reaffirm the covenants and affirmations contained in said Addendum and
incorporate the same into this Sixth Amendment.

    WHEREAS,
Owner and Kiewit are parties to that certain Engineering, Procurement and

and

     

    WHEREAS,
Owner and Kiewit desire to amend the Contract as set forth below.

     

    NOW,
THEREFORE, in consideration of the premises and the mutual covenants herein
contained, Owner and Kiewit agree as follows;

     

    1.           Capitalized
terms not defined herein shall have the meaning set forth in the
Contract.

     

    2.           The

following language is inserted in lieu thereof:

     

    “Kiewit guarantees that Substantial
Completion of the Work will be  achieved no later than June 30, 2009
(“Guaranteed Substantial Completion Date”).”

     

    3.           The
third sentence of Section 5.1 of the Contract is hereby amended by inserting the
following language after the phrase “provided, however,” on the last line of
page 12 of the Contract:

     

    “such
Base LDs shall not commence with until the 31st Day
after the Guaranteed Substantial Completion Date (i.e. Day 1 under item (i)
above shall be such 31st Day
after the Guaranteed Substantial Completion Date) and provided further, however,
.. . .”

     

    4.           Section
5.3 Early Completion Bonus
of the Contract is deleted in its entirety and there shall be no early
completion bonus under the Contract.

     

    5.           For
all Work performed under the Contract prior to September 22, 2008 (i.e. for Work

Owner will  make monthly progress payments in accordance with Section
8.3.  For all Work performed under the Contract from and after
September 22, 2008, notwithstanding any language of the second, third and fourth
sentences of Section 8.3 to the contrary, Owner shall pay for such Work in nine
(9) equal monthly installments.  Such nine (9) equal monthly
installments shall be determined as 

     

     

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    follows:
(i) first, an amount equal to the initial Contract Sum of Two Hundred Thirty
Million Seventeen Thousand Four Hundred Sixteen and no/100 Dollars
($230,017,416) shall be adjusted (up or down) for any agreed upon changes to the
Contract Sum as a result of any agreed upon Change Orders, and for any
adjustments to the Contract Sum under the fourth sentence of Section 8.1 for
Work performed prior to September 22, 2008, (ii) second, all progress payments
paid by Owner for Work performed under the Contract prior to September 22, 2008
(excluding any Excluded Taxes included in such progress payments) shall be
subtracted from the amount determined under item (i) above; for the avoidance of
doubt, all amounts paid by Owner or its affiliates under the AWA and the Pre-EPC
Agreement shall be considered as progress payments paid by Owner, (iii) third,
the amount determined under item (ii) above shall be increased by any Excluded
Taxes which Owner and Kiewit estimate, as of October 1, 2008, will be owed by
Owner under Section 8.1 for Work performed from and after September 22, 2008,
(iv) fourth, the amount determined under item (iii) above shall be adjusted up
or down for any adjustments to the Contract Sum under the fourth sentence of
Section 8.1 which Kiewit and Owner estimate, as of October 1, 2008, will occur
for Work to be performed from and after September 22, 2008, and (v) fifth, the
amount determined under item (iv) shall be the amount to be paid by Owner in
nine (9) equal monthly installments (each installment being the amount
determined under item (iv) divided by nine (9)) commencing with Work performed
under the Contract from and after September 22, 2008, for which the first of
such nine (9) installments will be paid by Owner in November 2008 and the last
of such nine (9) installments will be paid by Owner in July 2009, subject to the
payment process hereafter set forth in this Section 8.3.  However, the
last of these nine (9) monthly installment payments shall be subject to
adjustment to reflect any difference, up or down, between the total amount owed
by Owner under this Contract for the Work and the total amount paid by Owner
under this Contract for the Work (including payment of such ninth (9th)
monthly installment before any such adjustment and including credits for all
amounts paid by Owner or its affiliates under the AWA and the Pre-EPC
Agreement).”

     

    6.           The
Applications for Payment and supporting documentation to be submitted by Kiewit
to Owner under Section 8.3 of the Contract pertaining to the nine (9)
installment payments which are described in paragraph 5. of this Amendment shall
contain the same information as Applications for Payment and supporting
documentation previously submitted by Kiewit as well as the calculation of the
installment payments with reasonable supporting documentation; provided,
however, each Monthly Progress Invoice shall also include line items identifying
the difference (both for the current period and on a cumulative basis) between
what the progress payment(s) would have been had Section 8.3 of the Contract not
been amended as set forth in paragraph 5. of this Amendment and the installment
payment(s) determined under Section 8.3 of the Contract as amended under
paragraph 5. of this Amendment.

     

    7.           The
corn grind date in order, in part, for Plant Startup to occur under the Contract
is targeted to occur on May 30, 2009.

     

    8.           Except
as set forth above, all terms of the Contract shall remain in full force and
effect.

     

    9.           This
Amendment may be executed by Kiewit and Owner in any number of counterparts,
each of which shall be deemed an original instrument, but all of which together
shall constitute one and the same instrument.  Execution may be
evidenced by facsimile
