EXHIBIT 10.10  


 
 

ETHANOL MARKETING AGREEMENT    
    


This
Ethanol Marketing Agreement ("Agreement") is made and entered into as of the 14th day of October 2002 by and between VeraSun Energy Corporation, a South Dakota corporation ("VERASUN") and

In
consideration of the mutual terms and conditions contained herein, the Parties agree as follows: 


	1.
	Terms and Termination



	A.
	The
term of this Agreement shall commence on the first day of ethanol sales and continue for a primary term of two (2) years and thereafter, renewing for consecutive two
(2) year terms, unless terminated by either party with at least six (6) months prior written notice without cause.



	B.
	In
addition, this Agreement may be terminated under the circumstances set out below.

	C.
	Schedule
all loads with VERASUN.



	D.
	Extend
any alliance volume buying power of discounting to VERASUN.

CONFIDENTIAL  


 
 

EXHIBIT "A"    
    


	1.
	Commercial Objective:    To the extent commercially feasible as determined in AREI's good faith judgment in accordance with
the provisions of this Exhibit "A", AREI will not disadvantage the Pooled Net Price to be paid VERASUN under the Agreement, as a result of its Purchase/Resale Program.



	2.
	Defined Terms



	

	"Alliance Partners"—shall mean the group of ethanol producers that have agreed to exclusively
commit substantially all of their ethanol production to AREI for purposes of AREI marketing their ethanol.



	

	"Purchase/Resale Program"—shall mean the program administrated by AREI, independent of VERASUN
or other Alliance Partners, whereby AREI purchases ethanol from non-Alliance Partners for the purpose of selling to customers, independent of the Pooled Market Alliance Volume.



	

	"Contract Segment"—shall mean the type of ethanol contract used in selling ethanol. Contracts
are segmented into the following categories:



	

	Fixed Contracts—whereby a buyer agrees to purchase a volume of ethanol from AREI at a particular
time, over a period of time, for a fixed price;



	

	Spot—whereby a buyer agrees to buy a volume of ethanol from AREI at a specific time, or over a
period of time, for a price that varies over the term of the contract and is based on a mutually agreed upon market index;



	

	Gas Plus—whereby a buyer agrees to buy a volume of ethanol from AREI at a particular time, or
over a period of time, for a price that is determined by the sum of: a gasoline market index (e.g. NYMEX, CARB), plus a fixed amount. The gas plus segment is further segmented by the gasoline market
index used in determining the price.






	3.
	Business Rules



	

	The
following describes the business rules AREI will follow and the methodology AREI will employ to measure its performance against the commercial objective
set forth above with contracts beginning effective October 1, 2003.



	A.
	To
the extent commercially feasible, AREI will attempt to maintain its total mix of Alliance Partner sales contracts, as follows: 









	 
	Contract Segment
 
	 	Low
	 	Target % of

Total Gallons

Sold
	 	High

	 	Fixed Price	 	20%	 	33%	 	45%
	 	Gas Plus	 	20%	 	33%	 	45%
	 	Spot	 	20%	 	33%	 	45%





	B.
	Prior
to entering into a contract for the sale of ethanol of a Contract Segment type specified in 3.A. above originating from the Purchase/Resale Program (a "New Resale Contract") AREI
will compare the average netback price (on a cents per gallon basis) being realized from the sale of that portion of the Pooled Market Alliance Volumes being sold under then existing contracts of the
same Contract Segment (with such average netback price to be calculated on the same basis as the Net Pooled Price, except limited to the specific Contract Segment type at issue) (herein the "Alliance
Contract Segment Net Pooled Price") against the average net back price (on a cents per gallon basis before purchase/resale margin) being realized from the sale of that portion of the quantities of
ethanol being purchased under the Purchase/Resale 










Program
and being sold under then existing contracts of the same Contract Segment under the Purchase/Resale Program (with such average netback price to be calculated on a basis similar to that used in
calculating the Net Pooled Price except using Purchase/Resale Program volumes rather than Pooled Market Alliance Volumes). Where a New Resale Contract will be a Gas Plus Contract Segment type, only
contracts having the same gasoline index will be used in making the above comparison. Whenever possible and to the extent commercially feasible, AREI will only enter into a New Resale Contract of a
particular Contract Segment type when the then existing Purchase/Resale Contract Segment Net Pooled Price before purchase/resale margin (after including such New Resale Contract) will be less than or
equal to the then existing Alliance Contract Segment Net Pooled Price, both as determined on the basis of then existing contracts of the same Contract Segment type. 



	C.
	AREI
may still enter into Purchase/Resale Program contracts for good commercial reasons.






	4.
	Reporting



	

	AREI
will monitor the activities set forth in 3. above and report monthly by Contract Segment to VERASUN on:




	•
	Alliance
Ethanol Average Market Price



	•
	Breakdown
of Pooled Costs



	•
	Pooled
Net Price



	•
	Pooled
Market Alliance Volumes



	•
	Average
Purchase/Resale Market Price



	•
	Breakdown
of Purchase/Resale Costs



	•
	Average
Purchase/Resale Net Price Before Margin



	•
	Purchase/Resale
Volume



	•
	Differences
by Contract Segment of Alliance Ethanol Average Market Price and Pooled Net Price compared to Average Purchase/Resale Market Price and Average Purchase/Resale
Net Price







	5.
	Revisions



	

	—AREI
shall have the right to amend or eliminate this Exhibit "A" (a "Contract Change") subject to the following: 



        A.    Any
such Contract Change shall require VERASUN's written consent, with such consent not to be unreasonably withheld. For purposes of the foregoing, VERASUN shall not
withhold its consent to any amendment to this Exhibit "A" as long as such amendment will not have, in VERASUN's reasonable judgment, an adverse economic effect on VERASUN under the Agreement. 


        B.    VERASUN
shall have thirty (30) days from receipt of AREI's written notice of a proposed Contract Change to notify AREI in writing of whether or not VERASUN
consents to such Contract Change. If VERASUN notifies AREI in writing within such thirty (30) day period of its consent to such Contract Change or fails to provide written notice to AREI within
such thirty (30) day period of its non-consent to such Contract Change then such Contract Change shall be effective as of the date set forth in AREI's written notice; provided,
however, if such Contract Change will not have an adverse economic effect on VERASUN under the Agreement it shall also be effective as of the date set forth in AREI's written notice, whether or not
such consent is given by VERASUN. 


        C.    Subject
to B. above, if VERASUN provides written notice of its non-consent to the Contract Change within thirty (30) days of its receipt of AREI's
written notice of such Contract Change, then the Contract Change shall not be effective.

        5.B.    Commission.    AREI shall deduct from the Pooled Net Price a commission equal to [*]
percent [*] of the Pooled Net Price. The total commission shall not exceed [*] for the first [*] gallons produced on an annual
