Credit and the Company agree as follows:

SECTION 1. Supplements. In the event the Company desires to borrow from Farm
Credit and the Company has satisfied the conditions precedent set forth in
Section 7 of this Master Loan Agreement (the “MLA”), Farm Credit will lend to
the Company, (or in the event Farm Credit and the Company desire to consolidate
any existing loans hereunder) pursuant to a Supplement to this agreement (a
“Supplement”) and other provisions hereof. Each Supplement will set forth the
amount of the loan, the purpose of the loan, the interest rate or rate options
applicable to that loan, the repayment terms of the loan, and any other terms
and conditions applicable to that particular loan. Each loan will be governed by
the terms and conditions contained in this agreement and in the Supplement
relating to the loan.

SECTION 2. Sale of Participation Interests and Appointment of Administrative
Agent. The Company acknowledges that concurrent with the execution of this MLA

November 20, 2006, (“Agency Agreement”), Farm Credit and CoBank appointed CoBank
to act as Administrative Agent (“Agent”) to act in place of Farm Credit
hereunder and under the Supplements and any security documents to be executed
thereunder. All funds to be advanced hereunder shall be made by Agent, all
repayments by the Company hereunder shall be made to Agent, and all notices to
be made to Farm Credit hereunder shall be made to Agent. Agent shall be solely

entitled to rely on (and shall incur no liability to the Company in acting on)
any request or direction furnished in accordance with the terms thereof.

SECTION 4. Repayment. The Company’s obligation to repay each loan shall be
evidenced by the promissory note set forth in the Supplement relating to that
loan or by such replacement note as Agent shall require. Agent shall maintain a

SECTION 12. Events of Default. Each of the following shall constitute an “Event
of Default” under this agreement:

(A) Payment Default. The Company should fail to make any payment to Agent, or
purchase any equity in Farm Credit, when due.

(B) Representations and Warranties. Any representation or warranty made or
deemed made by the Company herein or in any Supplement, application, agreement,
certificate, or other document related to or furnished in connection with this
agreement or any Supplement, shall prove to have been false or misleading in any
material respect on or as of the date made or deemed made.

(C) Certain Affirmative Covenants. The Company or, to the extent required
hereunder, any Subsidiary should fail to perform or comply with Sections 9(A)
through 9(H)(ii), 9(H)(vi) through 9(H)(viii) or any reporting covenant set
forth in any Supplement hereto, and such failure continues for 15 days after
written notice thereof shall have been delivered by Agent to the Company.

(D) Other Covenants and Agreements. The Company or, to the extent required
hereunder, any Subsidiary should fail to perform or comply with any other
covenant or agreement contained herein or in any other Loan Document or shall
use the proceeds of any loan for an unauthorized purpose.

(E) Cross-Default. The Company should, after any applicable grace period, breach
or be in default under the terms of any other agreement between the Company and
Farm Credit.

(F) Other Indebtedness. The Company or any Subsidiary should fail to pay when
due any indebtedness to any other person or entity for borrowed money or any
long-term obligation for the deferred purchase price of property (including any
capitalized lease), or any other event occurs which, under any agreement or
instrument relating to such indebtedness or obligation, has the effect of
accelerating or permitting the acceleration of such indebtedness or obligation,
whether or not such indebtedness or obligation is actually accelerated or the
right to accelerate is conditioned on the giving of notice, the passage of time,
or otherwise.

(G) Judgments. A judgment, decree, or order for the payment of money shall be
rendered against the Company or any Subsidiary in an amount exceeding
$100,000.00 and either: (i) enforcement proceedings shall have been commenced,
(ii) a Lien prohibited under Section 10(B) hereof shall have been obtained, or
(iii) such judgment, decree, or order shall continue unsatisfied and in effect
for a period of 20 consecutive days without being vacated, discharged,
satisfied, or stayed pending appeal.

(H) Insolvency, Etc. The Company or any Subsidiary shall: (i) become insolvent
or shall generally not, or shall be unable to, or shall admit in writing its
inability to, pay its debts as they come due; or (ii) suspend its business
operations or a material part thereof or make an assignment for the benefit of
creditors; or (iii) apply for, consent to, or acquiesce in the appointment of a
trustee, receiver, or other custodian for it or any of its property or, in the
absence of such application, consent, or acquiescence, a trustee, receiver, or
other custodian is so appointed; or (iv) commence or have commenced against it
any proceeding under any bankruptcy, reorganization, arrangement, readjustment
of debt, dissolution, or liquidation Law of any jurisdiction.

(I) Material Adverse Change. Any material adverse change occurs, as reasonably
determined by Agent, in the Company’s financial condition, results of operation,
or ability to perform its obligations hereunder or under any instrument or
document contemplated hereby.

(J) Revocation of Guaranty. Any guaranty, suretyship, subordination agreement,
maintenance agreement, or other agreement furnished in connection with the
Company’s obligations hereunder and under any Supplement shall, at any time,
cease to be in full force and effect, or shall be revoked or declared null and
void, or the validity or enforceability thereof shall be contested by the
guarantor, surety or other maker thereof (the “Guarantor”), or the Guarantor
shall deny any further liability or obligation thereunder, or shall fail to
perform its obligations thereunder, or any representation or warranty set forth
therein shall be breached, or the Guarantor shall breach or be in default under
the terms of any other agreement with Agent (including any loan agreement or
security agreement), or a default set forth in Subsections (F) through
(H) hereof shall occur with respect to the Guarantor.

SECTION 13. Remedies. Upon the occurrence and during the continuance of an Event
of Default or any Potential Default, Farm Credit shall have no obligation to
continue to extend credit to the Company and may discontinue doing so at any
time without prior notice. For all purposes hereof, the term “Potential Default”
means the occurrence of any event which, with the passage of time or the giving
of notice or both would become an Event of Default. In addition, upon the
occurrence and during the continuance of any Event of Default, Farm Credit or
Agent may, upon notice to the Company, terminate any commitment and declare the
entire unpaid principal balance of the loans, all accrued interest thereon, and
all other amounts payable under this agreement, all Supplements, and the other
Loan Documents to be immediately due and payable. Upon such a declaration, the
unpaid principal balance of the loans and all such other amounts shall become
immediately due and payable, without protest, presentment, demand, or further
notice of any kind, all of which are hereby expressly waived by the Company. In
addition, upon such an acceleration:

(A) Enforcement. Farm Credit or Agent may proceed to protect, exercise, and
enforce such rights and remedies as may be provided by this agreement, any other
Loan Document or under Law. Each and every one of such rights and remedies shall
be cumulative and may be exercised from time to time, and no failure on the part
of Farm Credit or Agent to exercise, and no delay in exercising, any right or
remedy shall operate as a waiver thereof, and no single or partial exercise of
any right or remedy shall preclude any other or future exercise thereof, or the
exercise of any other right. Without limiting the foregoing, Agent may hold
and/or set off and apply against the Company’s obligations to Farm Credit cash
collateral held by Farm Credit or Agent, or any balances held by Farm Credit or
Agent for the Company’s account (whether or not such balances are then due).

(B) Application of Funds. Agent may apply all payments received by it to the
Company’s obligations to Farm Credit in such order and manner as Agent may elect
in its sole discretion.

In addition to the rights and remedies set forth above: (i) if the Company fails
to purchase any equity in Farm Credit when required or fails to make any payment
to Agent when due, then at Agent’s option in each instance, such payment shall
bear interest from the date due to the date paid at 4% per annum in excess of
the rate(s) of interest that would otherwise be in effect on that loan; and
(ii) after the maturity of any loan (whether as a result of acceleration or
otherwise), the unpaid principal balance of such loan (including without
limitation, principal, interest, fees and expenses) shall automatically bear
interest at 4% per annum in excess of the rate(s) of interest that would
otherwise be in effect on that loan. All interest provided for herein shall be
payable on demand and shall be calculated on the basis of a year consisting of
360 days.

SECTION 14. Broken Funding Surcharge. Notwithstanding any provision contained in
any Supplement giving the Company the right to repay any loan prior to the date
it would otherwise be due and payable, the Company agrees to provide three
Business Days’ prior written notice for any prepayment of a fixed rate balance
and that in the event it repays any fixed rate balance prior to its scheduled
due date or prior to the last day of the fixed rate period applicable thereto
(whether such payment is made voluntarily, as a result of an acceleration, or
otherwise), the Company will pay to Agent a surcharge in an amount equal to the
greater of: (i) an amount which would result in Farm Credit, Agent, and all
subparticipants being made whole (on a present value basis) for the actual or
imputed funding losses incurred by Farm Credit, Agent, and all subparticipants
as a result thereof; or (ii) $300.00. Notwithstanding the foregoing, in the
event any fixed rate balance is repaid as a result of the Company refinancing
the loan with another lender or by other means, then in lieu of the foregoing,
the Company shall pay to Agent a surcharge in an amount sufficient (on a present
value basis) to enable Farm Credit, Agent, and all subparticipants to maintain
the yield they would have earned during the fixed rate period on the amount
repaid. Such surcharges will be calculated in accordance with methodology
established by Farm Credit, Agent, and all subparticipants (copies of which will
be made available to the Company upon request).

SECTION 15. Complete Agreement, Amendments. This agreement, all Supplements, and
all other instruments and documents contemplated hereby and thereby, are
intended by the parties to be a complete and final expression of their
agreement. No amendment or modification of this Agreement shall be effective
unless in writing signed by both parties hereto. No waiver of any provision
hereof, and no consent to any departure by either party herefrom, shall be
effective unless approved in writing by the other party, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. In the event this agreement is amended or restated,
each such amendment or restatement shall be applicable to all Supplements
hereto.

SECTION 16. Other Types of Credit. From time to time, Farm Credit may extend
other types of credit to or for the account of the Company to expedite or
facilitate the loans extended hereunder. In the event the parties desire to do
so under the terms of this agreement, such extensions of credit may be set forth
in any Supplement hereto and this agreement shall be applicable thereto.

SECTION 17. Applicable Law. Except to the extent governed by applicable federal
law, this agreement and each Supplement shall be governed by and construed in
accordance with the laws of the State of Colorado, without reference to choice
of law doctrine.

SECTION 18. Notices. All notices hereunder shall be in writing and shall be
deemed to be duly given upon delivery if personally delivered or sent by

expenses of counsel retained or employed by Agent, including expenses of
in-house counsel of Agent) incurred by Agent and any participants from Farm
Credit in connection with the origination, administration, collection, and
enforcement of this agreement and the other Loan Documents, including, without
limitation, all costs and expenses incurred in perfecting, maintaining,
determining the priority of, and releasing any security for the Company’s
obligations to Farm Credit, and any stamp, intangible, transfer, or like tax
payable in connection with this agreement or any other Loan Document.

SECTION 20. Effectiveness and Severability. This agreement shall continue in
effect until: (i) all indebtedness and obligations of the Company under this
agreement, all Supplements, and all other Loan Documents shall have been paid or
satisfied; (ii) Agent has no commitment to extend credit to or for the account
of the Company under any Supplement; and (iii) either party sends written notice
to the other terminating this agreement. Any provision of this agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability without invalidating the remaining provisions hereof or
thereof.

SECTION 21. Successors and Assigns. This agreement, each Supplement, and the
other Loan Documents shall be binding upon and inure to the benefit of the
Company and Farm Credit and their respective successors and assigns, except that
the Company may not assign or transfer its rights or obligations under this
agreement, any Supplement or any other Loan Document without the prior written
consent of Agent.

SECTION 22. Participations, Etc. From time to time, Farm Credit may sell to one
or more banks, financial institutions or other lenders a participation in one or
more of the loans or other extensions of credit made pursuant to this agreement.
However, no such participation shall relieve Farm Credit of any commitment made
to the Company under any Supplement hereto. In connection with the foregoing,
Farm Credit may disclose information concerning the Company and its Subsidiaries
to any participant or prospective participant, provided that such participant or
prospective participant agrees to keep such information confidential. Farm
Credit agrees that all Loans that are made by Farm Credit and that are retained
for its own account and are not included in a sale of participation interest
shall be entitled to patronage distributions in accordance with the bylaws of
Farm Credit and its practices and procedures related to patronage distribution.
Accordingly, all Loans that are included in a sale of participation interest
shall not be entitled to patronage distributions from Farm Credit. A sale of
participation interest may include certain voting rights of the participants
regarding the loans hereunder (including without limitation the administration,
servicing and enforcement thereof). Farm Credit agrees to give written
notification to the Company of any sale of participation interests.

SECTION 23. Counterparts. This agreement, each Supplement and any other Loan
Document may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which, when so executed, shall be
deemed to be an original and shall be binding upon all parties and their
respective permitted successors and assigns, and all of which taken together
shall constitute one and the same agreement.

SECTION 24. Administrative Fee. The Company agrees to pay to Agent on
November 1, 2007, and on each November 1 thereafter, for as long as the Company
has commitments from Farm Credit, an administrative fee in the amount of
$35,000.00.

SECTION 25. Assumed Master Loan Agreement. The parties acknowledge that the
Company has assumed the Master Loan Agreement dated as of February 17, 2006,
between Farm Credit and Advanced BioEnergy, LLC, as the same may have been
amended from time to time (the “Advanced MLA”), together with all obligations
thereunder and under all Supplements, security documents, and other documents
related thereto. The parties agree that the Advanced MLA shall remain in full
force and effect concurrently with this MLA, provided, however, that to the
extent of any inconsistencies between this MLA and the Advanced MLA, the terms
and conditions of this MLA (including without reporting covenants, financial
covenants, and negative and affirmative covenants) shall prevail, and the
Advanced MLA shall be deemed amended accordingly. Consistently with the
foregoing, all Conditions Precedent to lending under this MLA shall apply to,
and be binding upon, any lending under the Advanced MLA.

IN WITNESS WHEREOF, the parties have caused this agreement to be executed by
their duly authorized officers as of the date shown above.
