                          U.S. Water Services Agreement

                             East Kansas Agri-Energy

TERM

U.S. Water Services agrees to provide the necessary water treatment chemicals,
service program and for a period of three years from the startup of the plant
which is expected to be approximately Fall of 2005 INVESTMENT

 Customer agrees to pay U.S. Water Services:

   /X/ $84,633 annually for specialty water treatment chemicals and testing
       reagents (schedule A-1). The annual amount is based on nameplate ethanol
       production of 35 million gallons per year.

   /X/ $ 10,000 One time fee for Waterworks. (schedule B-1) details the
       components and function of the "Waterworks" automation and equipment
       upgrade package.

   / / _________ for engineering services, environmental support services and
       plant start up assistance (appendix A).

The payments will be made in monthly installments of $7052.75, according to
invoices generated by U.S. Water Services. State and local taxes will be added
to each invoice unless a tax exemption is on file with U.S. Water Services. This
agreement will automatically renew each year. Price increases may be taken on
the anniversary date of the contract provided that a 30-day notice of the
increase is provided to the customer.

 WATER WORKS OPTION
Waterworks Option selected ____U____Yes_________No
 The customer agrees to purchase "Waterworks" integration software and hardware.
 Payments for "Waterworks" will be billed as a one time invoice on the first day
 of the month that chemicals are delivered to the plant site.

BUNDLED DISCOUNT
 Selecting US Water Services as both the equipment and water treatment equipment
 supplier will entitle the customer to a one time bundled discount equal to 5%
 of the total capital equipment package or a 10% discount taken as a monthly
 credit over the length of the initial agreement
 ______We select 5% up front capital discount = $5801.00
 __U __We select 10% discount applied against the monthly service agreement
for three years = $322.28/month

NOT TO EXCEED COSTS FOR CHEMICALS

 U.S. Water Services agrees to limit the annual chemical cost for the specialty
 water treatment chemicals in schedule A-1 to a maximum of $84,633,provided the
 chemicals are applied within the recommended limits specified by U.S. Water
 Services. The not to exceed cost does not include start up cleaning chemicals,
 RO cleaners, consumables such as filters or replacement parts. If annual
 production and water usage are above nameplate design the customer maybe billed
 at a rate of $2418.00 / 1 million gallons additional ethanol production.
 Nameplate design and water efficiencies are stated below. Operational variances
 from the design basis below may result in additional charges. Charges will be
 reconciled at the end of every quarter. All efficiencies are based on a
 quarterly average.

   -  Cooling tower makeup does not exceed 22 million gallons/qtr.
   -  Cooling tower average cycles maintains over 3 cycles of concentration
   -  Boiler condensate return is maintained above 93%
   -  Boiler Steam load averages 75,000 pounds per hour
   -  Boiler makeup does not exceed an average of 14 gallons per minute of RO
      water.
      Make up water quality remains constant.
