                           responsible for scheduling all shipments of Owner's

                           to market Owner's Ethanol through storage facilities
                           such as Williams or Kaneb pipeline terminals, Owner
                           will pay all lease and throughput cost associated
                           with such leases.

                  d.       FREIGHT. When necessary to Market Owner's Ethanol,

                  e.       CUSTOMER CREDITWORTHINESS. Marketer will make
                           reasonable efforts to review the creditworthiness of

                           believes should be rejected. Owner will have the

                           recommendations and/or reports and notify Marketer in
                           writing of any customers in addition to the

                           to any customer rejected by Owner or Marketer.

                  f.       ACCOUNTS RECEIVABLE. Marketer will make reasonable
                           efforts to collect any past due accounts. However,
                           Marketer shall not be required to initiate litigation

                           authorized to turn over to collection agencies a
                           delinquent account unless Owner determines that it
                           will assume responsibility for collecting the
                           account. Any collection agency fees resulting from
                           the collections process will be borne by Owner. All

         7.       VALUE-ADDED OPPORTUNITIES. Marketer and Owner mutually
                  recognize that on occasion Marketer will be able to develop a
                  sale opportunity for Owner's ethanol that is above the market
                  value for sales typically completed on a spot market or
                  contract rollover basis (a "value-added transaction").
                  Examples of value-added transactions include the building of
                  new markets, time exchanges, location exchanges, rack pricing,
                  and negotiation of spread differentials. The parties
                  acknowledge that new value-added opportunities not yet known
                  to the parties are expected to be developed by Marketer in the
                  future.

                  Owner and Marketer acknowledge that for value-added
                  opportunities, the Marketing Fee is insufficient to compensate
                  Marketer for additional income and profits generated for
                  Owner. In order to facilitate the completion of value-added
                  opportunities which occur and disappear quickly within the
                  market, Owner agrees to identify representatives of Owner with
                  authority to approve value-added transactions. Marketer will
                  upon identification of a value-added opportunity present to
                  any one of Owner's representatives the value-added opportunity
                  for consideration. Marketer will explain to Owner's
                  representative the value-added opportunity and a proposed
                  compensation arrangement for Marketer. Owner has complete and
                  sole discretion to accept or reject the value-added
                  opportunity and fee proposal. If agreed upon by Owner's
                  representative, Marketer will confirm in writing to Owner's
                  representative the agreement of the parties regarding the
                  value-added opportunity. In this case, Marketer shall complete
                  the value-added transaction in accordance with the agreement
                  of the parties. If Owner's representative declines to
                  participate in the value-added opportunity, then Marketer will
                  not complete the value-added opportunity for Owner's account.

         8.       REPORTING. Marketer will provide Owner with the following
                  reports on a schedule described below during the term of this
                  Agreement:

                  Shipping Orders-                   Daily
                  Market Information-                Weekly
                  Sales Summary-                     Monthly

                  Owner will provide Marketer with the following reports on a
                  scheduled described below during the term of this Agreement:

                  Daily Production-                  Daily
                  Combined Shipping Schedule-        Daily

<PAGE>

                  In addition to the aforementioned reports, Owner will timely
                  inform Marketer of daily inventories, plant shutdowns, daily
                  production projections, and any other information requested by
                  Marketer in which to perform under this Agreement.

         9.       DISCONTINUATION OF PRODUCTION. In the event that Owner wishes
                  to discontinue or reduce the production of Ethanol, Owner will
                  notify Marketer one (1) year in advance of Owner's decision so
                  that all contract commitments made by Marketer for Owner may
                  be met. If less than one (1) year notice of discontinuance or
                  reduction of production is provided to Marketer, or if
                  unforeseen circumstances cause Owner to cease or reduce
                  production at its plant, Owner grants to Marketer the power to
                  buy in Ethanol short falls for the account of the Owner on any
                  unfilled contracts, and that any associated losses will be
                  reimbursed by Owner to Marketer.

         10.      LIABILITY. Any and all liability related to the Ethanol,
                  including but not limited to Ethanol quality and the handling,
                  transportation and storage of Ethanol, shall remain the sole
                  responsibility of Owner.

         11.      INSURANCE. Marketer will furnish Owner with an insurance
                  certificate verifying that Marketer has liability insurance.

         12.      ENTIRE AGREEMENT AND AMENDMENT. This Agreement contains the
                  entire Ethanol Marketing Agreement between the parties. No
                  oral statements, representations or prior written matter not
                  contained in this Agreement shall have any effect regarding
                  products marketing. This Agreement shall not be amended or
                  modified in any manner except by a writing executed by both
                  parties.

         13.      INDEMNIFICATION OF MARKETER. Owner shall indemnify, hold
                  harmless and defend Marketer, and its officers, directors,
                  employees and agents from and against any and all claims,
                  actions, damages, liabilities and expenses, including but not
                  limited to, attorney's and other professional fees, in

                  services provided under the terms and conditions of this
                  Agreement, and for Owner's breach of this Agreement, except
                  that Owner shall not indemnify, hold harmless and defend
                  Marketer from (i) the negligent or intentional acts of
                  Marketer and its officers, directors, employees and agents,
