                              RAW GRAINS AGREEMENT*

     THIS RAW GRAINS MARKETING AGREEMENT (this "Agreement"), made and entered
into this 12th of November, 2004, by and among East Kansas Agri-Energy, LLC, a
Kansas limited liability company ("EKAE"), and United Bio Energy Ingredients,
LLC, a Kansas limited liability company ("UBEI").

                              W I T N E S S E T H :

     WHEREAS, EKAE intends to construct and own an ethanol plant, located near
Garnett, Kansas (the "Plant");

     WHEREAS, EKAE desires to buy and UBEI desires to sell all raw grains
required for any ethanol production at the Plant (the "Raw Grains");

     WHEREAS, the parties desire to purchase and sell Raw Grains, and receive
and provide such services, in accordance with the fees, price formula, payment,
delivery and other terms set forth in this Agreement.

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and conditions herein contained, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged by
both parties, it is hereby agreed:

     1.   COMMITMENT AND TERM. Subject to the terms of this Agreement, UBEI
hereby agrees to sell, and EKAE hereby agrees to purchase, all Raw Grains
required for ethanol production at the Plant. The initial term of this Agreement
shall be for five (5) years. The parties shall execute a memorandum setting
forth the actual date of commencement of the term, which shall be approximately
6 months before substantial completion of the Plant. Unless earlier terminated
in accordance with this Agreement, this Agreement shall be automatically renewed
for successive one (1) year terms thereafter unless either party gives written
notice to the other party of its election not to renew, not later than ninety
(90) days prior to the expiration of the then current term.

     2.   PRICE AND PAYMENT.

          A.   PRICE. For all Raw Grains delivered to the Plant by UBEI, EKAE
shall pay UBEI a price equal to the F.O.B. Plant Price plus [*] ($[*]) per
bushel. For purposes of this provision, the "F.O.B. Plant Price" shall mean the
actual cash procurement price of Raw Grains, plus all reasonable and necessary
expenses incurred by UBEI in delivering the Raw Grains to the Plant, whether
incurred prior to or during the term of this Agreement, less any quality
discounts using the Price Discount Schedule contained in EXHIBIT A.

*Portion omitted pursuant to a request for confidential treatment and filed
separately with the Securities and Exchange Commission.

                                       1
<Page>

          B.   PAYMENT. On a daily basis, weekends and holidays excluded, EKAE
shall provide UBEI with certified weight certificates for the previous day's
receipts of Raw Grains. Transmittal of said weight certificates may be
electronically transmitted in a medium acceptable to the parties. The
certificates shall determine the quantity and quality of Raw Grains received at
the Plant for each delivery. UBEI shall invoice EKAE, via the agreed to
electronic medium, the F.O.B. Plant Price defined in paragraph 2.A above for all
properly documented deliveries. Invoices shall be due two (2) business days
after receipt of said invoice by EKAE, and EKAE shall make payment of funds to
UBEI via wire transfer into an account designated by UBEI. Unless EKAE has
provided prior written notice to UBEI of a dispute with respect to said invoice,
failure to pay in accordance with such terms shall entitle UBEI to impose a late
payment fee of Two Tenths of One Cent ($.002) per bushel per calendar day until
such invoice is paid in full. EKAE shall have the right to inspect copy and/or
audit UBEI's expense records and Raw Grains invoices and contracts during normal
business hours at the corporate offices of UBEI. If any such inspection or audit
shall reveal an overpayment made to UBEI, UBEI shall immediately pay EKAE the
amount of the overpayment together with interest from the date that such
overpayment was made at the prime rate in effect on the date of the overpayment
as reported in the Wall Street Journal. The expense of any such inspection or
audit shall be borne by EKAE unless a material overpayment is revealed, then, in
such case, the reasonable expense of such inspection or audit shall be borne by
UBEI.

          C.   BEST EFFORTS. UBEI agrees to use best efforts to achieve the
lowest price for Raw Grains available under prevailing market conditions.

     4.   ON-SITE MERCHANDISER NOT INCLUDED. The provisions of this Agreement do
not include a grain merchandiser on-site at the Plant during the term of this
Agreement.

     5.   DELIVERY AND TITLE.

          A.   PLACE. The place of delivery for all Raw Grains sold by UBEI
pursuant to this Agreement shall be F.O.B. Plant. UBEI and its agents shall be
given access to the Plant in a manner and at all times reasonably necessary and
convenient for UBEI to make delivery as provided herein. EKAE shall direct the
unloading and receiving of all Raw Grains purchased hereunder. All labor and
equipment necessary to load or unload trucks or rail cars shall be supplied by
EKAE without charge to UBEI. EKAE agrees to handle the unloading and receiving
of the Raw Grains in a good and workmanlike manner in accordance with UBEI's
reasonable requirements and in accordance with normal industry practice. EKAE
shall maintain the truck/rail unloading facilities in safe operating condition
in accordance with normal industry standards.

          B.   UNLOADING SCHEDULE. On Friday of each week during the term of
this Agreement, UBEI shall give EKAE a schedule of quantities of Raw Grains to
be delivered by rail by UBEI during the next receiving week (Monday through
Sunday). In the event UBEI delivers some or all of the Raw Grains by truck, UBEI
shall give EKAE sufficient advance notice to allow EKAE to provide the required
unloading services. EKAE shall provide the labor, equipment and facilities
necessary to meet UBEI's unloading schedule and shall be responsible

                                       2
<Page>

for UBEI's additional costs resulting from EKAE's failure to do so; provided,
however, if UBEI has not given notice as provided herein, EKAE is obligated only
to use its best efforts to accommodate UBEI's unloading schedule and EKAE shall
not be responsible for any additional costs incurred by UBEI resulting from
EKAE's failure to do so. All freight charges shall be the responsibility of UBEI
and shall be billed directly to UBEI, and said charges shall be included in the
price charged to EKAE. UBEI shall order and supply trucks as scheduled for truck
shipments.

          C.   PRODUCTION SCHEDULE. UBEI shall provide Raw Grains in quantities
necessary to permit EKAE to maintain its usual production schedule; provided,
however, that UBEI shall not be responsible for failure to schedule receipts of
Raw Grains unless EKAE shall have provided to UBEI, at least five (5) days prior
to the beginning of the next month, notice of the estimated schedule for
production for such month. On Wednesday of each week, EKAE shall provide UBEI
notice of the schedule for actual production for the following production week
(Monday through Sunday). EKAE shall inform UBEI daily of inventory and
production status by 8:30 a.m. CDT.

     For purposes of this paragraph, notification of such production schedules
will be sufficient if made by facsimile or electronically as follows:

          UBEI, to the attention of Ron Hansen, Facsimile number 316-796-0944,
          Email address: ron.hansen@unitedbioenergy.com; and

          EKAE, to the attention of General Manager, Facsimile number _________,
          Email address:________________________.

     Or to such other representatives of UBEI and EKAE as they may designate to
the other in writing.

          D.   TITLE. Title, risk of loss and responsibility for the quality of
Raw Grains shall pass to EKAE upon unloading the Raw Grains at the Plant. Prior
to unloading, EKAE shall have the right to inspect and reject any Raw Grain
delivery that does not meet the quality standards set forth in this Agreement.

     6.   QUANTITY AND WEIGHTS.

          A.   NO REPRESENTATION. It is understood that the Raw Grains required
for the production of the ethanol shall be determined by EKAE's production
schedule and that no warranty or representation has been made by EKAE as to the
exact quantities of Raw Grains required.

          B.   ESTIMATE. The estimated amount of Raw Grains required for the
production of ethanol at the Plant is thirteen million (13,000,000) bushels per
year.

          C.   SCALES. The weight of Raw Grains delivered by UBEI to the Plant
shall be established by weight certificates. EKAE shall obtain truck and rail
weights on the scales at

                                       3
<Page>

the Plant, which shall be maintained by EKAE as required by applicable laws,
rules and regulations. Whenever EKAE's scales are unavailable or inoperable, any
certified scales may be used, at EKAE's sole cost and expense, until EKAE's
scales are available and operable. These inbound weight certificates shall be
determinative of the quantity of Raw Grains for which EKAE is obligated to pay
pursuant to paragraph 2 above, except that Raw Grains procured by UBEI on the
basis of origin weights shall be invoiced at the actual origin weight, with an
allowance for shrinkage not greater than three percent (3%), as measured against
the destination weight.

          D.   RAIL CARS. Except as otherwise consented to by EKAE, all rail
cars for Raw Grains shall be grain hopper cars.

     7.   QUALITY.

          A.   STANDARDS. UBEI understands that EKAE intends to utilize the Raw
Grains purchased from UBEI as primary base stock for ethanol production and that
said Raw Grains are subject to minimum quality standards for such use. UBEI
warrants that Raw Grains delivered to the Plant shall meet the Corn
Specification contained in the Quality Standards in EXHIBIT A attached hereto or
the Sorghum Specification contained in the Quality Standards in EXHIBIT B
attached hereto and shall be acceptable under current industry standards in the
ethanol production industry. The Quality Standards in EXHIBIT A and EXHIBIT B
are subject to change as may be mutually agreed in writing by and between the
parties, provided, however, that such changes shall be in conformance with
generally acceptable industry standards.

          B.   COMPLIANCE. UBEI warrants that at the time of delivery the Raw
Grains will not be adulterated or misbranded within the meaning of the Federal
Food, Drug and Cosmetic Act and that the Raw Grains may lawfully be introduced
into interstate commerce under said Act. Unless otherwise agreed between the
parties to this Agreement, and in addition to other remedies permitted by law,
EKAE may, without obligation to pay, reject any Raw Grains before unloading for
the failure of the Raw Grains to comply with the representations and warranties
in this paragraph. Actual unloading of Raw Grains at the Plant shall waive
EKAE's rights to reject Raw Grains on the grounds of noncompliance with the
representations and warranties in this Agreement. Should any of the Raw Grains
be seized or condemned by any federal or state department or agency for any
reason, except noncompliance by EKAE with applicable federal or state
requirements, such seizure or condemnation shall operate as a rejection by EKAE
of the Raw Grains seized or condemned and EKAE shall not be obligated to offer
any defense in connection with the seizure or condemnation. If UBEI fails to
deliver Raw Grains as required by this Agreement, or EKAE rejects in good faith
any tender of delivery of Raw Grains, EKAE may in good faith and without
unreasonable delay, make any reasonable purchase of Raw Grains in substitution
of the amount due from UBEI and credit any costs incurred in obtaining the
substitute Raw Grains against any amounts owed by EKAE to UBEI.

          C.   PRODUCT TESTING. If UBEI knows, should know or reasonably
suspects that any Raw Grains delivered by UBEI to the Plant do not meet the
standards set forth in this Agreement, UBEI shall promptly so notify EKAE so
that such Raw Grains can be tested before being unloaded at the Plant. If EKAE
knows or reasonably suspects that any Raw Grains

                                       4
<Page>

delivered by UBEI to the Plant do not meet the standards set forth in this
Agreement, then EKAE may obtain independent laboratory tests of the affected Raw
Grains. If such Raw Grains are tested and found to comply with all warranties
made by UBEI herein, then EKAE shall pay all reasonable testing costs and if the
Raw Grains are found not to comply with such warranties, UBEI shall pay all
reasonable testing costs and EKAE shall be allowed to reject such delivery
regardless of whether the affected Raw Grains have been unloaded.

          D.   NON-SPECIFICATION PRODUCTS. If UBEI delivers Raw Grains which do
not meet the Corn Specification contained in EXHIBIT A or the Sorghum
Specification contained in EXHIBIT B, then EKAE agrees to purchase such Raw
Grains in accordance with the Price Discount Schedule contained in EXHIBIT A or
EXHIBIT B, unless such Raw Grains may be rejected in accordance with EXHIBIT A
or EXHIBIT B and this Agreement.

     8.   INSURANCE.

          A.   POLICIES. EKAE warrants to UBEI that all EKAE's employees engaged
in the acquisition of Raw Grains for the Plant shall be covered as required by
law by worker's compensation and unemployment compensation insurance. UBEI
warrants to EKAE that all UBEI's employees or agents of UBEI present at the
Plant shall be covered as required by law by worker's compensation and
unemployment compensation insurance.

          B.   COVERAGES. During the term of this Agreement, EKAE shall purchase
and maintain insurance in such amounts as it may reasonably determine. UBEI
shall be named as an additional insured on all such policies. All such policies
shall contain provisions to the effect that in the event of payment of any loss
or damage the insurers will have no rights of recovery against any of the
insureds or additional insureds thereunder. EKAE waives all rights against UBEI
and its employees and agents for all losses and damages caused by, arising out
of or resulting from any of the perils or causes of loss covered by such
policies and any other property insurance applicable to the Plant. Also during
the term of this Agreement, UBEI shall purchase and maintain commercial general
liability insurance, with combined single limits of not less than $2,000,000
which shall be endorsed to require at least thirty (30) days notice to EKAE
prior to the effective date of any termination or cancellation of coverage. EKAE
shall be named as an additional insured on all such policies and UBEI shall
provide a certificate of insurance to EKAE to establish the coverage maintained
by the commencement date of this Agreement.

          C.   UBEI VEHICLES. UBEI agrees to carry such insurance on its
vehicles and personnel operating on EKAE's property as UBEI reasonably deems
appropriate or as required by law. The parties acknowledge that UBEI may elect
to self insure its vehicles. Upon request, UBEI shall provide a certificate of
insurance to EKAE to establish the coverage maintained by UBEI.

          D.   CONSEQUENTIAL DAMAGES. EACH PARTY TO THIS AGREEMENT UNDERSTANDS
THAT NO OTHER PARTY MAKES ANY GUARANTEE, EXPRESS OR IMPLIED, TO ANY OTHER OF
PROFIT, OR OF ANY PARTICULAR ECONOMIC RESULTS FROM TRANSACTIONS CONTEMPLATED BY
THIS AGREEMENT. IN NO EVENT SHALL ANY PARTY BE LIABLE FOR SPECIAL,

                                       5
<Page>

COLLATERAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES FOR ANY ACT OR OMISSION COMING
WITHIN THE SCOPE OF THIS AGREEMENT, OR FOR BREACH OF ANY OF THE PROVISIONS OF
THIS AGREEMENT, EVEN IF IT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES,
SUCH EXCLUDED DAMAGES INCLUDE, BUT ARE NOT LIMITED TO, LOSS OF GOOD WILL, LOSS
OF PROFITS, LOSS OF USE, AND INTERRUPTION OF BUSINESS.

          E.   OTHER CLAIMS. Except as provided in paragraph 8.D above, nothing
herein shall be construed as a waiver by either party against the other party of
claims, causes of action or other rights which either party may have or
hereafter acquire against the other party for damage or injury to its agents,
employees, invitees, property, equipment or inventory, or third party claims
against the other party for damage or injury to other persons or the property of
others.

     9.   REPRESENTATIONS AND WARRANTIES.

          A.   Each party represents and warrants that it is an entity in good
standing under the laws that it is organized and has all the requisite power and
authority to carry on its business as it has been and to own, lease, and operate
the properties and assets used in connection therewith.

          B.   In addition to the representations and warranties herein
regarding the quality of Raw Grains, UBEI represents and warrants that the Raw
Grains delivered to EKAE shall be free and clear of liens and encumbrances.

          C.   Each individual executing this Agreement in a representative
capacity, by his or her execution hereof, represents and warrants that such
person is fully authorized to do so on behalf of the respective party hereto,
and that no further action or consent on the part of the party for whom such
signatory is acting is required for the effectiveness and enforceability of this
Agreement against such party, following such execution.

     10.  TERMINATION.

          A.   FOR CAUSE. Either party may terminate this Agreement without
liability for cause by providing thirty (30) days prior written notice to the
other party. For purposes of this paragraph, "cause" shall include, but not be
limited to, the happening of an event of default discussed in paragraph 11
below, or any other material breach of any provision of this Agreement, or
material violation of any applicable law, regulation or ruling.

          B.   WITHOUT CAUSE. Either party may terminate this Agreement without
cause by providing ninety (90) days prior written notice to the other party. If
EKAE terminates this Agreement without cause during the initial term, then EKAE
shall pay to UBEI, within thirty (30) days of termination, an amount equal to
the product of three (3) multiplied by the average monthly fee paid to UBEI,
under paragraph 2.A above, for the six (6) months prior to the termination date,
or if the fee has been paid for less than six (6) months, by the average of the
monthly fee for the number of months such monthly fee has been paid to UBEI.

     11.  EVENTS OF DEFAULT. The occurrence of any of the following shall be an
event of default under this Agreement: (1) failure of either party to make
payment to the other when due, if such nonpayment has not been cured within five
(5) days of written notice thereof; (2) default by either party in the
performance of any material covenant, condition or agreement imposed upon that
party by this Agreement, if such nonperformance has not been cured within five
(5) days of written notice thereof; or (3) if either party shall become
insolvent, or make a general assignment for the benefit of creditors or to an

adjudicated bankrupt, or file a petition in bankruptcy and such petition is not

limiting the foregoing, the parties shall have the following remedies whether in

Agreement in accordance with the provisions of paragraph 10.

due to events beyond its reasonable control, including, but not limited to,
fire, storm, flood, earthquake, explosion, act of the public enemy or terrorism,
riots, civil disorders, public emergency, sabotage, strikes, lockouts, labor
disputes, labor shortages, war, stoppages or slowdowns initiated by labor,
transportation embargoes, acts of God, or acts or regulations or priorities of
the federal, state or local government or branches or agencies thereof;
provided, however, both parties agree to use reasonable efforts to correct any
failure or delay in performance.

     14.  INDEMNIFICATION.

          A.   Except as otherwise provided in this Agreement, EKAE shall
indemnify, defend and hold UBEI and its officers, directors, employees and
agents harmless, from any and all losses, liabilities, damages, expenses
(including reasonable attorneys' fees), costs, claims, demands, that UBEI or its

                               ETHANOL AGREEMENT*

     THIS ETHANOL AGREEMENT (this "Agreement"), made and entered into this 12th
day of November, 2004, by and among East Kansas Agri-Energy, LLC, a Kansas
limited liability company ("EKAE"), and United Bio Energy Fuels, LLC, a Kansas
limited liability company ("UBEF").

                              W I T N E S S E T H :

     WHEREAS, EKAE intends to construct and own an ethanol plant, located near
Garnett, Kansas (the "Plant");

     WHEREAS, EKAE desires to sell and UBEF desires to buy all the fuel grade

Garnett, Kansas ("Plant");

     WHEREAS, the parties desire to purchase and sell the Ethanol, and receive
and provide such services, in accordance with the fees, price formula, payment,
delivery and other terms set forth in this Agreement.

     NOW, THEREFORE, in consideration of the promises and the mutual covenants
and conditions herein contained, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by both parties, it
is hereby agreed:

     1.   FEES. During the term of this Agreement, EKAE shall pay UBEF a fee of
[*] ($[*]) for each gallon of Ethanol produced at the Plant and shipped by UBEF
(the "Marketing Fee").

     2.   TERM. The initial term of this Agreement shall be for five (5) years.
The parties shall execute a memorandum setting forth the actual date of
commencement of the term, which shall be approximately 6 months before
substantial completion of the Plant. Unless earlier terminated in accordance
with this Agreement, this Agreement shall be automatically renewed for
successive one (1) year terms thereafter unless either party gives written
notice to the other party of its election not to renew, not later than ninety
(90) days prior to the expiration of the then current term.

accurate sales and expense records and to provide such records to EKAE upon
request. EKAE shall have the right to inspect, copy and/or audit UBEF's sales
invoices and expense records at any time during normal business hours at the
corporate office of UBEF. If any such inspection or audit shall reveal a
deficiency in a payment due to EKAE, UBEF shall immediately pay EKAE the amount
of the deficiency together with interest from the date that such payment should
have been made at the prime rate in effect on the date of the underpayment as
reported in the Wall Street Journal. The expense of any such inspection or audit
shall be borne by EKAE unless a material deficiency in payment is revealed,
then, in such case, the reasonable expense of such inspection or audit shall be
borne by UBEF.

          C.   BEST EFFORTS. UBEF agrees to use its best efforts to achieve the
highest price of Ethanol available under prevailing market conditions as judged
in good faith by UBEF and agrees to communicate to EKAE the terms and conditions
of ethanol sales.

          D.   COLLECTION. UBEF shall be responsible for all customer billing
and account servicing, including, but not limited to, the collection of amounts
owed UBEF by its customers, UBEF shall bear all costs associated with such
billing and collection activities, and UBEF shall assume all losses due to
failure of its customers to pay their account.

          E.   FUTURE SALES BY UBEF. UBEF shall not contract for the sale of
Ethanol to its customers more than one hundred eighty (180) days in advance,
unless EKAE explicitly approves the price and terms of any such contract and
provides notice of such approval to UBEF. Upon notice of termination, UBEF shall
not contract for the sale of Ethanol to its customers more than ninety (90) days
in advance, unless EKAE explicitly approves the price and terms of any such
contract and provides notice of such approval to UBEF. UBEF will advise EKAE
weekly and update EKAE monthly on all outstanding contractual obligations, and
the terms thereof.

     4.   FEES AND EXPENSES. Unless otherwise specifically provided for herein,
and to the extent not already included in the price of the Ethanol, EKAE shall
be responsible for any and all fees and expenses, including but not limited to
fees assessed by any State or other regulatory agency, incurred or assessed on
any Ethanol, whether for licensing, dues, branding, packaging, inspecting, or
otherwise. EKAE shall, as a result of its responsibility for such expenses,
retain all rights to any name, branding, and packaging of the Ethanol upon
termination

                                       2

          F.   TITLE. Title and risk of loss shall pass to UBEF at the point in
time when loading the Ethanol into trucks or rail cars has been completed and
delivery to UBEF of the bill of lading for each such shipment.

          G.   RAIL CAR LEASES. UBEF shall be responsible for estimating the
number of rail car leases required to handle the transportation of the Ethanol
and for negotiating the terms of and executing such rail car leases; provided,
however, that any and all rail car leases executed by UBEF shall be in
substantially the same form as a standard rail car lease previously approved by
EKAE for this purpose. Upon the termination of this Agreement, any and all
existing rail car leases for the transport of Ethanol will be assigned to EKAE,
who will assume and be obligated to the terms and conditions of said leases.
EKAE shall reimburse UBEF for any reasonable expenses incurred by UBEF
associated with such rail car leases, to the extent such expenses are not
already accounted for in the price of the Ethanol.

          H.   RAIL CONTRACTS. UBEF shall negotiate, in consultation with EKAE,
the terms of rail contracts and rates on behalf of EKAE. The rail contracts
shall be placed in the sole name of EKAE.

     6.   QUANTITY AND WEIGHTS.

          A.   PRODUCTION AMOUNT. EKAE represents and warrants that it will sell
to UBEI and UBEI represents and warrants that it will purchase from EKAE all
Ethanol produced at the Plant. However, it is understood that total production
amount of Ethanol shall be determined by EKAE's production schedule and that no
warranty or representation has been made by EKAE as to the exact quantities or
timing of Ethanol to be produced pursuant to this Agreement.

          B.   ESTIMATE. The estimated production of Ethanol at the Plant by
EKAE, to be sold to UBEF, is approximately 35 million (35,000,000) gallons of
Ethanol per year on a ratable production schedule per month, and EKAE shall use
its best efforts to produce such amount of Ethanol.

          C.   SCALES.

                                       4
<Page>

               The quantity of Ethanol delivered to UBEF from the Plant shall be
established by meter or weight certificates, obtained from meters or scales at
the Plant, which shall be maintained by EKAE as required by applicable laws,
rules and regulations. The outbound meter or weight certificates shall be
determinative of the quantity of the Ethanol for which UBEF is obligated to pay
pursuant to paragraph 3 above, and such quantity shall be measured using net 60
degree Fahrenheit compensated gallons.

          D.   RAIL CARS.

               All rail cars for Ethanol shall be the largest allowable tank
cars as determined by UBEF. With respect to Ethanol, all such cars shall meet
all applicable Department of Transportation and Federal Railroad Administration
specifications for shipping ethanol. EKAE agrees that such tank cars for Ethanol
shall be loaded to full visible capacity at the Plant. If not loaded to full
visible capacity, EKAE shall pay in full the portion of freight charges
allocable to the unused capacity of the car.

     7.   QUALITY.

          A.   STANDARDS. EKAE understands that UBEF intends to sell the Ethanol
purchased from EKAE as a gasoline blending component and that the same is
subject to minimum quality standards for such use. EKAE warrants that the
Ethanol produced by the Plant and delivered to UBEF shall conform to the minimum
quality standards outlined in EXHIBIT A or EXHIBIT B (ETHANOL FOR CALIFORNIA) as
may be applicable, attached hereto, as each may be amended from time to time.
Notwithstanding anything in this Agreement to the contrary, EKAE provides no
warranty greater than those received from ICM, Inc. pursuant to the Design-Build
Contract dated August 9, 2004.

          B.   COMPLIANCE. Unless otherwise agreed between the parties to this
Agreement, and in addition to other remedies permitted by law, UBEF may, without
obligation to pay, reject any of the Ethanol before loading for the failure of
the Ethanol to comply with the representations and warranties in this paragraph.
Actual loading of Ethanol shall not waive UBEF's rights to reject Ethanol on the
grounds of noncompliance with the representations and warranties in this
Agreement unless UBEF had actual knowledge of such noncompliance prior to
loading. Should any of the Ethanol be seized or condemned by any federal or
state department or agency for any reason, except noncompliance by UBEF with
applicable federal or state requirements, such seizure or condemnation shall
operate as a rejection by UBEF of the Ethanol seized or condemned and UBEF shall
not be obligated to offer any defense in connection with the seizure or
condemnation. However, UBEF agrees to cooperate with EKAE in connection with the
defense of any quality or other product claims, or any claims involving
governmental seizure or condemnation. UBEF shall be fully responsible for, and
shall indemnify EKAE against any liability for, or claims arising from, any
failure by UBEF to deliver Ethanol to its customers, except to the extent that
delivery fails due to the fault of EKAE. When rejection occurs pursuant to this
paragraph, at its option, UBEF may:

               (1) Dispose of the rejected Ethanol after first offering EKAE a
reasonable opportunity of examining and taking possession thereof, if the
condition of the Ethanol reasonably appears to UBEF to permit such delay in
making disposition; or

                                       5
<Page>

               (2) Dispose of the rejected Ethanol in any manner directed by
EKAE which UBEF can accomplish without violation of applicable laws, rules,
regulations or property rights; or

               (3) If any of the Ethanol is seized or condemned by any federal
or state department or agency or if UBEF has no available means of disposal of
rejected Ethanol and EKAE fails to direct UBEF to dispose of it as provided
herein, UBEF may return the rejected Ethanol to EKAE, upon which event UBEF's
obligations with respect to said rejected Ethanol shall be deemed fulfilled.
Title and risk of loss shall pass to EKAE promptly upon such seizure or
condemnation or rejection by UBEF.

               (4) EKAE shall reimburse UBEF for all costs reasonably incurred
by UBEF in storing, transporting, returning and disposing of the rejected
Ethanol. UBEF shall have no obligation to pay EKAE for rejected Ethanol and may
deduct reasonable costs and expenses to be reimbursed by EKAE from amounts
otherwise owed by UBEF to EKAE.

          C.   PRODUCT TESTING. If EKAE knows or reasonably suspects that any
Ethanol produced by the Plant is adulterated or misbranded, or, are outside of
minimum quality standards set forth in EXHIBIT A or EXHIBIT B, EKAE shall
promptly so notify UBEF so that such Ethanol can be independently tested before
entering interstate commerce. If UBEF knows or reasonably suspects that any
Ethanol produced by the Plant is adulterated or misbranded, or, is outside of
minimum quality standards set forth in EXHIBIT A or EXHIBIT B, then UBEF may
obtain independent laboratory tests of the affected Ethanol. If such Ethanol is
independently tested and found to comply with all warranties made by EKAE
herein, then UBEF shall pay all testing costs, and if the Ethanol is found not
to comply with such warranties, EKAE shall pay all testing costs.

          D.   CHANGES IN STANDARDS. Upon written notice to UBEF, said minimum
quality standards are subject to change at the discretion of EKAE. Sufficient
notice of any such change shall be deemed to be given to UBEF if EKAE gives
written notification to UBEF at least thirty (30) days prior to such change.
Such changes must be in conformance to generally acceptable industry standards.

     8.   RETENTION OF SAMPLES. EKAE will take an origin sample of the Ethanol
from each truck or rail car before each shipment leaves the Plant, using
industry standard sampling methodology. EKAE will label these samples to
indicate the date of shipment of the truck, rail car, or pickup number involved.
EKAE shall also retain the samples and labeling information for no less than six
(6) months after shipment of the Ethanol.

     9.   INSURANCE.

          A.   POLICIES. EKAE warrants to UBEF that all EKAE's employees engaged
in the removal of Ethanol from the Plant shall be covered as required by law by
worker's compensation and unemployment compensation insurance.

          B.   COVERAGES. During the term of this Agreement, EKAE shall purchase
and maintain such insurance in such amounts as it may reasonably determine. UBEF
shall be

                                       6
<Page>

named as an additional insured on all such policies. All such policies shall
contain provisions to the effect that in the event of payment of any loss or
damage the insurers will have no rights of recovery against any of the insureds
or additional insureds thereunder. EKAE waives all rights against UBEF and its
employees and agents for all losses and damages caused by, arising out of or
resulting from any of the perils or causes of loss covered by such policies and
any other property insurance applicable to the Plant. Also during the term of
this Agreement, UBEF shall purchase and maintain commercial general liability
insurance, with combined single limits of not less than $2,000,000 which shall
be endorsed to require at least thirty (30) days notice to EKAE prior to the
effective date of any termination or cancellation of coverage. EKAE shall be
named as an additional insured on all such policies and UBEF shall provide a
certificate of insurance to EKAE to establish the coverage maintained by the
commencement date of this Agreement.

          C.   UBEF VEHICLES. UBEF agrees to carry such insurance on its
vehicles and personnel operating on EKAE's property as UBEF reasonably deems
appropriate or as required by law. The parties acknowledge that UBEF may elect
to self insure its vehicles. UBEF shall provide a certificate of insurance to
EKAE to establish the coverage maintained by UBEF.

          D.   CONSEQUENTIAL DAMAGES. EACH PARTY TO THIS AGREEMENT UNDERSTANDS
THAT NO OTHER PARTY MAKES ANY GUARANTEE, EXPRESS OR IMPLIED, TO ANY OTHER OF
PROFIT, OR OF ANY PARTICULAR ECONOMIC RESULTS FROM TRANSACTIONS CONTEMPLATED BY
THIS AGREEMENT. IN NO EVENT SHALL ANY PARTY BE LIABLE FOR SPECIAL, COLLATERAL,
INCIDENTAL, OR CONSEQUENTIAL DAMAGES FOR ANY ACT OR OMISSION COMING WITHIN THE
SCOPE OF THIS AGREEMENT, OR FOR BREACH OF ANY OF THE PROVISIONS OF THIS
AGREEMENT, EVEN IF IT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, SUCH
EXCLUDED DAMAGES INCLUDE, BUT ARE NOT LIMITED TO, LOSS OF GOOD WILL, LOSS OF
PROFITS, LOSS OF USE, AND INTERRUPTION OF BUSINESS.

          E.   OTHER CLAIMS. Except as provided in paragraph 9.D above, nothing
herein shall be construed as a waiver by either party against the other party of
claims, causes of action or other rights which either party may have or
hereafter acquire against the other party for damage or injury to its agents,
employees, invitees, property, equipment or inventory, or third party claims
against the other party for damage or injury to other persons or the property of
others.

     10.  REPRESENTATIONS AND WARRANTIES.

          A.   Each party represents and warrants that it is an entity in good
standing under the laws that it is organized and has all the requisite power and
authority to carry on its business as it has been and to own, lease, and operate
the properties and assets used in connection therewith.

          B.   In addition to the representations and warranties herein
regarding the quality of Ethanol, EKAE represents and warrants that the Ethanol
delivered to UBEF shall be free and clear of liens and encumbrances.
Notwithstanding the foregoing, UBEF acknowledges that EKAE's senior lender has a
security interest in all of the assets of EKAE subject to EKAE's ability to make
sales in the ordinary course of business.

                                       7

signatory is acting is required for the effectiveness and enforceability of this
Agreement against such party, following such execution.

          D.   Each party warrants that it is now in material compliance, and
during the entire term of this Agreement will remain in material compliance,
with all applicable federal, state, local, and foreign laws, ordinances, orders,

     12.  EVENTS OF DEFAULT. The occurrence of any of the following shall be an
event of default under this Agreement: (1) failure of either party to make
payment to the other when due, if such nonpayment has not been cured within five
(5) days of written notice thereof; (2) default by either party in the
performance of any material covenant, condition or agreement imposed upon that
party by this Agreement, if such nonperformance has not been cured within five
(5) days of written notice thereof, unless such obligation cannot be reasonably
performed within such five (5) day period, then within a reasonable time; or (3)
if either party shall become insolvent, or make a general assignment for the
benefit of creditors or to an agent authorized to liquidate any substantial
amount of its assets, or be adjudicated bankrupt, or file a petition in
bankruptcy and such petition is not dismissed within ninety (90) days following
the date of filing, or apply to a court for the appointment of a receiver for
any of its assets or properties with or without consent, and such receiver shall
not be discharged within sixty (60) days following appointment.

     13.  REMEDIES. Upon the happening of an event of default under paragraph
12, the parties hereto shall have all remedies available under applicable law
with respect to an event of default by the other party, including but not
limited to the recovery of reasonable attorneys' fees and other costs and
expenses. Without limiting the foregoing, the parties shall have the following
remedies whether in addition to or as one of the remedies otherwise available to
them: (1) to declare all amounts owed immediately due and payable; and (2) to
terminate this Agreement within thirty (30) days following the giving of notice
of default and opportunity to cure. Notwithstanding any other provision of this
Agreement, UBEF may offset against amounts otherwise owed to EKAE the price of
any Ethanol which fails to conform to any requirements of this Agreement.

     14.  OPEN CONTRACTS. Upon the termination of this Agreement, for whatever
reason, EKAE shall assume and be responsible for delivering any remaining
quantities of Ethanol required to be delivered by UBEF to its customers pursuant
to UBEF's contracts with the same, provided such contracts are to be delivered
by UBEF from the Plant. Prior to the termination of this Agreement, UBEF shall
provide EKAE with a listing of all such contracts and the quantities of Ethanol
to be delivered pursuant to the same to assist EKAE in completing deliveries
under these open contracts. EKAE agrees to assist UBEF in the collection of
amounts owed to UBEF from those customers receiving deliveries of Ethanol from
UBEF prior to the termination of this Agreement.

     15.  FORCE MAJEURE. Neither EKAE nor UBEF will be liable to the other for
any failure or delay in the performance of any obligation under this Agreement
due to events beyond its reasonable control, including, but not limited to,
fire, storm, flood, earthquake, explosion, act of the public enemy or terrorism,
riots, civil disorders, public emergency, sabotage, strikes, lockouts, labor
disputes, labor shortages, war, stoppages or slowdowns initiated by labor,
transportation embargoes, failure or shortage of materials, acts of God, or acts
or regulations or priorities of the federal, state or local government or
branches or agencies thereof.

     16.  INDEMNIFICATION.

          A.   BY EKAE. Except as otherwise provided in this Agreement, EKAE
shall indemnify, defend and hold UBEF and its officers, directors, employees and
agents harmless, from any and all losses, liabilities, damages, expenses
(including reasonable attorneys' fees),

costs, claims, demands, that UBEF or its officers, directors, employees or

(including reasonable attorneys' fees), costs, claims, demands, that EKAE or its
officers, directors, employees or agents may suffer, sustain or become subject
to, or as a result of (i) any misrepresentation or breach of warranty, covenant
or agreement of UBEF contained herein or (ii) UBEF's negligence or willful
misconduct.

          C.   Where such personal injury or death is the result of negligence
on the part of both EKAE and UBEF, each party's duty of indemnification shall be
in proportion to the percentage of that party's negligence or faults.

     17.  [*]. UBEF hereby acknowledges that EKAE is entering into separate
service agreements with certain affiliates of UBEF (i.e., United Bio Energy
Ingredients, LLC, United Bio Energy Management, LLC, and United Bio Energy

affiliates to EKAE under such agreements may include acting on behalf of EKAE
and/or performing certain duties or obligations of EKAE under the terms and

is no agency, partnership, joint venture or other joint or mutual enterprise or
undertaking created hereby. Nothing contained in this Agreement authorizes one
party to act for or on behalf of the other and neither party is entitled to
commissions from the other.

     19.  CONFIDENTIALITY. The parties agree to execute a Confidentiality and
Nondisclosure Agreement. Such Agreement shall remain in full force and effect
and shall apply and govern all disclosure and use of confidential information
