working capital for operating costs of the ethanol plant. Construction costs do not include the
cost associated with payment of lost profits connected with termination under §15.3 of the
DESIGN/BUILD CONSTRUCTION CONTRACT.

2.2 The CONSTRUCTION NOTE. The obligation of the BORROWER to repay the EXPANSION LOAN
shall be evidenced by the CONSTRUCTION NOTE. Notwithstanding any provisions of the CONSTRUCTION
NOTE, interest shall be payable at the rate provided therein only on such portions of the EXPANSION
LOAN proceeds as actually have been disbursed pursuant to this AGREEMENT.

2.3 Interest on the CONSTRUCTION NOTE. Interest on the CONSTRUCTION NOTE shall accrue at
the LIBOR RATE, plus three hundred ten basis points prior to acceleration or maturity, and nine
hundred ten basis points in excess of the LIBOR RATE in effect from time to time after maturity,
whether by acceleration or otherwise.

2.4 Repayment of the CONSTRUCTION NOTE. Interest only shall be payable quarterly,
commencing September 20, 2006, on the CONSTRUCTION NOTE. All outstanding principal and accrued but
unpaid interest shall be payable on the LOAN TERMINATION DATE.

2.5 EXPANSION TERM LOANS. The existing balance on the EXPANSION LOAN, as of COMPLETION
DATE will be restated and said balance will be paid by three new promissory notes, hereafter called
“FIXED RATE NOTE” (which will be the result of fifty {50%} percent of the EXPANSION LOAN),
“VARIABLE RATE NOTE”, and “LONG TERM REVOLVING NOTE” in the forms attached hereto as Exhibits “D”,
“E”, and “F”, which are by this reference made a part hereof. Those NOTES evidence “EXPANSION TERM
LOANS” and the LONG TERM REVOLVING NOTE evidences a “LONG TERM REVOLVING LOAN”. In addition, the
VARIABLE RATE NOTE shall include the then existing balance of TERM NOTE D. In addition, the LONG

     In addition, on the 20th day of every third month, commencing three months after

be calculated
by BANK based upon an amortization of the then outstanding balances of TERM NOTE D and TERM NOTE E,
which shall be allocated as follows:

	 	a.	 	first to accrued interest on LONG TERM REVOLVING NOTE;
	 
	 	b.	 	next to accrued interest on VARIABLE RATE NOTE;

	 
	 	c.	 	next to principal on VARIABLE RATE NOTE;

     After the VARIABLE RATE NOTE has been fully paid, such quarterly payments shall be allocated

principal and accrued interest under the EXPANSION TERM LOANS shall be due and payable on LOAN
TERMINATION DATE, if not sooner paid.

2.6 REVOLVING LOAN. BANK agrees to lend $5,000,000.00 to BORROWER pursuant to this
facility. BANK will credit proceeds of this revolving loan (“REVOLVING LOAN”) first to repay the
NOTE previously evidencing the REVOLVING LOAN, and thereafter to BORROWER’s deposit account with
the BANK, bearing number 110150455. Subject to the terms hereof, the BANK will lend the BORROWER,
from time to time until the LOAN TERMINATION DATE, such sums as the BORROWER may request by
reasonable same day notice to the BANK, received by the BANK not later than 11:00 A.M. of such day,
but which shall not exceed in the aggregate principal amount at any one time outstanding,
$5,000,000.00 (the “LOAN COMMITMENT”). The BORROWER may borrow, repay without penalty or premium
and reborrow hereunder, from the date of this AGREEMENT until the LOAN TERMINATION DATE, either the
full amount of the LOAN COMMITMENT or any lesser sum. It is the intention of the parties that the
outstanding balance of the REVOLVING LOAN shall not exceed the BORROWING BASE, and if at any time
said balance exceeds the BORROWING BASE, BORROWER shall forthwith pay BANK sufficient funds to
reduce the balance of the REVOLVING LOAN until it is in compliance with this requirement.

hundred basis points in excess of the LIBOR RATE in effect from time to time after maturity,

specified in the REVOLVING NOTE. Such REVOLVING NOTE may also provide for reductions in the
interest rate accrual, based upon BORROWER’s performance.

2.9 TERM NOTE C, TERM NOTE D, AND TERM NOTE E. The existing TERM NOTE C, TERM NOTE D, and
TERM NOTE E, executed pursuant to the 2003 AGREEMENT constitute OBLIGATIONS, and will be paid by
BORROWER according to the following schedule:

     On the first day of each quarter, commencing September 20, 2006, BORROWER shall pay to BANK
the scheduled principal payment shown in Schedule I, attached hereto and by this reference

- 10 -

 

made a part hereof, plus accrued interest on TERM NOTE C.

     In addition, on the first day of each quarter, commencing September 20, 2006, until

	 	c.	 	next to principal on TERM NOTE D;

2.10 LETTERS OF CREDIT. BANK will issue its letters of credit at BORROWER’s request, on BORROWER’s
account, pursuant to the BANK’s customary policies and with its standardized documents, in amounts
outstanding at no time exceeding $1,000,000.00 in the aggregate. This facility will be reviewed by
BANK and is subject to BANK’s annual renewal of the facility.

2.11 Payments and Prepayments. All principal, interest and fees due under this AGREEMENT,
the NOTES and the LOAN DOCUMENTS shall be paid in immediately available funds as contracted in this
AGREEMENT and no later than the payment due date set forth in the periodic statements mailed to the
BORROWER by the BANK. Should a payment come due on a day other than a BANKING DAY, then the
payment shall be made no later than the next BANKING DAY and interest shall continue to accrue
during the extended period.

     On the occasion of any prepayment of TERM NOTE C or TERM NOTE D, BORROWER will pay to BANK a
prepayment fee equal to one (1%) percent of the original principal amount of such NOTE. On the
occasion of any prepayment of CONSTRUCTION NOTE, or FIXED RATE NOTE and VARIABLE RATE NOTE, in
full, BORROWER will pay to BANK a prepayment fee calculated as follows: If the prepayment occurs
during the construction of the PROJECT or within the first three years of the FIXED RATE NOTE or
the VARIABLE RATE NOTE, a fee of Four Hundred Sixty-Three Thousand ($463,000.00) shall be paid to
BANK.

     The NOTES evidencing the OBLIGATIONS may also include requirements for compensation to the
BANK for prepayment of such NOTES evidencing fixed interest rates.

2.12 Fees. At CLOSING, the BORROWER shall pay to the BANK a commitment fee of $231,500.00,
which fee BORROWER agrees and acknowledges has been earned by BANK. On September 20, 2006, and the
same date in each year thereafter, the BORROWER shall pay to the BANK an Annual Servicing Fee of
$20,000.00, which fee BORROWER agrees and acknowledges has been earned by BANK; provided, however,
an Annual Servicing Fee shall not be due and payable on the LOAN TERMINATION DATE and the BANK
shall refund the Annual Servicing Fee on a pro rata basis if the Loan Termination Date occurs other
than on an anniversary of the COMPLETION DATE. The Annual Servicing Fee set forth in this
paragraph 2.12 replaces any obligation of BORROWER to pay a servicing fee pursuant to the 2003
AGREEMENT.

     BORROWER agrees to pay BANK an unused commitment fee on the unused portion of the REVOLVING
LOAN and of the LONG TERM REVOLVING LOAN, calculated and payable on a quarterly basis in arrears.
In the case of the LONG TERM REVOLVING LOAN, such unused commitment fee shall only be calculated
and due following COMPLETION DATE. Such unused

- 11 -

 

commitment fee shall vary, depending on BORROWER’s
ratio of INDEBTEDNESS to NET WORTH during the quarter being measured.

	 	 	 
	If such ratio is:
	 	Such fee shall be:

	 	20 basis points
	less than 1.00 : 1.00
	 	15 basis points
	less than 0.75 : 1.00
	 	15 basis points

actions required by a corporate or limited liability entity under applicable law to own the
PROPERTY and construct the PROJECT, and to execute and deliver, and to perform all of its
obligations under the LOAN DOCUMENTS to which it is a party.

5.2 Authorization of Borrowing; No Conflict as to Law or Other Agreements. The execution,
delivery and performance by the BORROWER of the LOAN DOCUMENTS and the borrowings from time to time
hereunder have been duly authorized by all necessary corporate actions of the BORROWER and do not
and will not (a) require any material consent or approval, or authorization, by any governmental
department, commission, board, bureau, agency or instrumentality, domestic or foreign, other than
those obtained and in full force and effect, (b) violate, in any material respect, any provision of
any law, rule or regulation or of any order, writ, injunction or decree presently in effect having
applicability to the BORROWER, or violate any provision of the Articles of Organization or
operating agreement of the BORROWER, (c) result in a breach of or constitute a default beyond any
applicable cure period under any indenture or loan or credit agreement or any other agreement,
lease or instrument to which the BORROWER is a party or by which it or its properties may be bound
or affected, or (d) other than PERMITTED LIENS and other than in favor of BANK, result in, or
require, the creation or imposition of any mortgage, deed of trust, pledge, lien, security interest
or

- 20 -

 

other charge or encumbrance of any nature to or with any other creditor of the BORROWER, in the
aggregate exceeding $100,000.00, upon or with respect to any of the properties now owned or
hereafter acquired by the BORROWER.

5.3 Legal Agreements. The LOAN DOCUMENTS to which it is a party constitute the legal,
valid and binding obligations of the BORROWER enforceable against the BORROWER in accordance with
their respective terms, and as to the LOAN DOCUMENTS to which BORROWER is not a party, BORROWER
believes such documents constitute the legal, valid and binding obligations of the parties thereto,
enforceable against such parties in accordance with their respective terms, except (a) as limited
by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general
application affecting enforcement of creditors’ rights generally, and (b) as limited by laws
relating to the availability of specific performance, injunctive relief, or other equitable
remedies.

5.4 License and Permits. The BORROWER has all necessary PERMITS required for construction
and operation of the PROJECT and the operation of its ethanol plant business, except those which
are not required for the current stage of construction of the PROJECT, or which cannot be obtained
until completion of the PROJECT.

5.5 Construction of the PROJECT. The PROJECT will be constructed in material compliance
with the PLANS; and will not encroach upon or overhang any easement or right-of-way on land not
constituting part of the PROPERTY. The PROJECT, both during construction and on COMPLETION DATE,
and the contemplated use thereof, will not violate in any material respect, any applicable zoning

record. The BORROWER agrees that it will furnish from time to time such satisfactory evidence with
respect thereto as may be required by the BANK.

5.6 Title to the PROPERTY. The BORROWER has good and marketable fee simple title to the
PROPERTY.

5.7 Financial Condition. The BORROWER has furnished to the BANK its financial statements
for periods through December 31, 2005 and May 31, 2006, as well as its cash flow projections dated

condition of the BORROWER on the dates thereof, and were prepared in GAAP format and on the basis
of assumptions deemed reasonable by the BORROWER. There has been no material adverse change in the
operations, properties or condition (financial or otherwise) of the BORROWER since the date of the
furnished financial statements and the PROJECTIONS and no additional borrowings have been made by
the BORROWER other than the borrowing contemplated hereby or approved by the BANK, or INDEBTEDNESS
secured by PERMITTED LIENS. No certificate or statement furnished to the BANK by or on behalf of
the BORROWER in connection with the transactions contemplated hereby contains any untrue statement
of a material fact or omits to state a material fact necessary in order to make the statements
contained therein or herein not misleading. To the best of the knowledge of the BORROWER, there is
no fact which materially

- 21 -

 

adversely affects or in the future (so far as the BORROWER now foresees)
may materially adversely affect the operation or prospects or condition (financial or other) of the
BORROWER or its properties or assets, which has not been set forth herein or in a certificate or
statement furnished to the BANK by the BORROWER.

5.8 Litigation. There are no actions, suits or proceedings pending or, to the knowledge of
the BORROWER, threatened against or affecting the BORROWER or the properties of the BORROWER before
any court or governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, which, if determined adversely to the BORROWER, would have a material adverse
effect on the financial condition, properties, or operations of the BORROWER.

5.9 Taxes. The BORROWER has filed all federal, state and local tax returns which to the
knowledge of the BORROWER are required to be filed, and the BORROWER has paid or caused to be paid
to the respective taxing authorities all taxes as shown on said returns or on any assessment
received by it to the extent such taxes have become due except those which the BORROWER is
contesting in good faith and with respect to which adequate reserves have been set aside.

5.10 No Default. There is no event, which is, or with notice or the lapse of time would
be, an EVENT OF DEFAULT.

5.11 ERISA. The BORROWER is in compliance in all material respects with the Employee
Retirement Income Security Act of 1974, as amended, and has received no notice to the contrary from

conditions or circumstances that could materially interfere with such compliance in the future; 2)
except for PERMITS that cannot be obtained until completion of the PROJECT, the BORROWER has
obtained all PERMITS, and approvals required by law for the operation of its business; and 3) the
BORROWER has not identified any “recognized environmental conditions,” as that term is defined by
the American Society for Testing and Materials in its standards for environmental due diligence,
which could subject the BORROWER to enforcement action if brought to the attention of appropriate
governmental authorities.

plant has all necessary electrical, gas, water, and sewer facilities in place for the proper
construction and operation of its ethanol plant. BORROWER has made adequate provision for all

6.1.10 The BORROWER will give the BANK prompt written notice of any material violation as to

proceeding involving it that might materially and adversely affect its operations, financial

6.2 Financial Covenants. At all times that any amounts are outstanding under this
AGREEMENT or the LOAN DOCUMENTS to which it is a party, unless the BANK shall otherwise agree in
writing, the BORROWER agrees to comply with the financial covenants described below, which shall be
calculated using GAAP consistently applied, except as they may be otherwise modified by the
capitalized definitions:

6.2.1 The BORROWER shall maintain a FIXED CHARGE COVERAGE RATIO, measured on a trailing
four quarters basis at the end of each full calendar quarter, of no less than 1.25 : 1.0.

- 25 -

 

6.2.2 The BORROWER shall maintain NET WORTH of not less than $50,000,000.00 at all times.
The required minimum NET WORTH of BORROWER, which is to be measured annually at the end of
each fiscal year of BORROWER, shall increase each fiscal year by an amount equal to the
greater of (a) $250,000.00 or (b) the amount of undistributed earnings
accumulated during the fiscal year just ended, but not including allowable distributions
attributable to the just ended fiscal year’s earnings.

6.2.3 The BORROWER shall determine, at each fiscal year end the amount of its EXCESS CASH
FLOW for said fiscal year. Within one hundred twenty days following the fiscal year ended
December 31, 2006, pay fifteen percent (15%) of such sum to BANK, to be applied to the
principal amount of TERM NOTE D. Within one hundred twenty days following each fiscal year
end thereafter, pay fifteen percent (15%) of such sum to BANK, to be applied to the
principal amount of the EXPANSION LOAN or the VARIABLE RATE NOTE, as applicable. Such
annual payment shall not release BORROWER from making any payment of principal or interest
otherwise required by any NOTE. No payment of EXCESS CASH FLOW shall be the cause of a
payment to BANK for interest rate breakage fees or otherwise result in any prepayment
penalty. BANK may require, after annual review of BORROWER’s financial statements, a change
to such percentage payment, provided, however, BORROWER’s obligation to pay such EXCESS CASH
FLOW to BANK shall not exceed twenty (20%) percent of such EXCESS CASH FLOW, nor will
BORROWER be required to pay recapture payments in excess of Four Million Dollars in any
single fiscal year, nor more than Eight Million Dollars in the aggregate.

6.2.4 BORROWER shall maintain the following minimum WORKING CAPITAL during the periods
stated below, measured continuously:

	 	 	 
	Period	 	Minimum WORKING CAPITAL
	 
	Closing through September 30, 2006
	 	$5,500,000.00
	 
	 	 
	October 1, 2006 through December 31, 2006
	 	$6,500,000.00
	 
	 	 
	January 1, 2007 and thereafter
	 	$7,000,000.00

For the purpose of this covenant, the amount of any reduction in any revolving feature of a
TERM LOAN shall constitute an addition to WORKING CAPITAL.

6.3 Affirmative Covenants. During the time period that any amounts are outstanding under
the NOTES, this AGREEMENT or the LOAN DOCUMENTS to which BORROWER is a party, unless the BANK
shall otherwise agree in writing the BORROWER shall:

- 26 -

the completion of the PROJECT, as well as casualty/umbrella (Commercial General
Liability) insurance, against all risks, including flood, earthquake, and mechanical

the property policies;

(ii) Casualty (Commercial General Liability) & Umbrella insurance (including
products and completed operations, operations of subcontractors, and contractual
liability insurance) with coverage in the amount of $2,000,000.00 in the form of

$1,000,000.00 Umbrella policy. The BANK’s interest shall be protected by naming the
BANK as an additional named insured on all such policies;

(iii) State worker’s compensation insurance, with statutory limits, and Employer’s
Liability coverage with coverage of no less than $500,000.00.

(iv) Business automobile liability insurance insuring all vehicles on the site,
including hired and non-owned liability with coverage in the amount of $2,000,000.00

clause (i) above shall contain an agreement of the insurer to give not less than
thirty (30) days’ advance written notice to the BANK in the event of cancellation of
such policy or change affecting the coverage there under. Acceptance of insurance
policies referred to above shall not bar the BANK from requiring additional
insurance, which it reasonably deems necessary.

BANK contracts with third parties at reasonable expense to make the inspection, to examine

statements of account pertaining to the PROJECT and to inspect upon reasonable notice all
books and records pertaining to its operations and to make extracts there from and copies
thereof.

6.3.7 Cause to be paid to the proper authorities when due all federal, state and local

conduct such inspections of the PROPERTY, PROJECT and BORROWER’s personal property subject
to the BANK’s security interest as the BANK may deem necessary for the protection of the
BANK’s interest. Provided, however, such inspections shall occur during regular business
hours, or such other time as the BORROWER and BANK may agree, and shall not unreasonably
interfere with BORROWER’s business operations. Any such

not to be unreasonably withheld by BANK.

6.3.14 Maintain hedging contracts (and applicable control agreements), or risk management
methods acceptable to BANK, as to BORROWER’s grain and utilities needs as well as ethanol

NOTES or this AGREEMENT or the LOAN DOCUMENTS to which BORROWER is a party, unless the BANK shall
otherwise agree in writing the BORROWER shall not:

7.2 Rights and Remedies. If an EVENT OF DEFAULT shall have occurred and be continuing, the
BANK may refrain from making any further disbursements hereunder (but the BANK may make
disbursements after the occurrence of such an EVENT OF DEFAULT without thereby waiving its rights
and remedies hereunder), and the BANK may exercise any or all of the following rights and remedies:

7.2.1 The BANK may declare the EXPANSION LOAN to be terminated, whereupon the same shall
forthwith terminate.

7.2.2 The BANK may declare the entire unpaid principal amount of the CONSTRUCTION NOTE then
outstanding, all interest accrued and unpaid thereon, and all other amounts payable under
this AGREEMENT to be forthwith due and payable, whereupon the CONSTRUCTION NOTE, all such
accrued interest and all such amounts shall become and be forthwith due and payable, without
presentment, demand, protest or further notice of any kind, all of which are hereby
expressly waived by the BORROWER.

7.2.3 The BANK may exercise and enforce its rights and remedies under any or all of the LOAN
DOCUMENTS.

7.2.4 The BANK may enter upon the PROPERTY, if allowed under applicable law, and take
possession thereof, together with the PROJECT then in the course of construction, and

the BORROWER (which authority is coupled with an interest and is irrevocable by the
BORROWER) to complete or cause to be completed the PROJECT, at the cost and expense of the
BORROWER. If the BANK elects to complete or cause to be completed the PROJECT, it may do so
according to the PLANS or according to such changes, alterations or modifications in and to
the PLANS as the BANK may deem reasonable and appropriate; and the BANK may enforce or
cancel all contracts let by the BORROWER relating to construction of the PROJECT, and/or let
other contracts which in the BANK’s sole judgment may seem advisable; and the BORROWER shall
forthwith turn over and duly assign to the

- 34 -

 

BANK, as the BANK may from time to time require,
contracts not already assigned to the BANK relating to construction of the PROJECT,
blueprints, shop drawings, bonds, building permits, bills and statements of accounts
pertaining to the PROJECT, whether paid or not, and any other instruments or records in the
possession of the BORROWER pertaining to the PROJECT. The BORROWER shall be liable under
this AGREEMENT to pay to the BANK, on demand, any amount or amounts reasonably expended by
the BANK in so completing the
PROJECT, together with any reasonable costs, charges, or expenses incident thereto or
resulting therefrom, all of which shall be secured by the LOAN DOCUMENTS. In the event that
a proceeding is instituted against the BORROWER for recovery and reimbursement of any moneys
expended by the BANK in connection with the completion of the PROJECT, a statement of such
expenditures, verified by the affidavit of an officer of the BANK, shall be prima facie
evidence of the amounts so expended and of the propriety of the necessity for such
expenditures; and the burden of proving to the contrary shall be upon the BORROWER. The BANK
shall have the right to apply any funds which it agrees to disburse hereunder to bring about
the completion of the PROJECT and to pay the costs thereof; and if such money so agreed to
be disbursed is insufficient, in the sole judgment of the BANK, to complete the PROJECT, the
BORROWER agrees to promptly deliver and pay to the BANK such sum or sums of money as the
BANK may from time to time demand for the purpose of completing the PROJECT or of paying any
liability, charge or expense which may have been incurred or assumed by the BANK under or in
performance of this AGREEMENT, or for the purpose of completing the PROJECT. It is expressly
understood and agreed that in no event shall the BANK be obligated, or liable in any way to
complete the PROJECT or to pay for the costs of construction thereof beyond the amount of
the EXPANSION LOAN.

7.2.5 The BANK may exercise any other rights and remedies available to it by law or
agreement.

SECTION 8 Miscellaneous.

8.1 Inspections. The BORROWER and the GENERAL CONTRACTOR shall be responsible for making
inspections of the PROJECT and PROPERTY during the course of construction and shall determine to
their own satisfaction that the work done or materials supplied by the GENERAL CONTRACTOR or any
SUBCONTRACTOR to whom payment is to be made out of each disbursement has been properly done or
supplied in accordance with the DESIGN/BUILD CONSTRUCTION CONTRACT. If any work done or materials
supplied by the GENERAL CONTRACTOR or any SUBCONTRACTOR are not satisfactory to the BORROWER and/or
its GENERAL CONTRACTOR and the same is not remedied within fifteen (15) days of the discovery
thereof, the BORROWER will immediately notify the BANK in writing of such fact. It is expressly
understood and agreed that the BANK and any party designated by the BANK may conduct such
inspections of the PROJECT, subject to the limitations expressed in this AGREEMENT, as BANK may
reasonably deem necessary for the protection of the BANK’s interest, and that any inspections which
may be made of the PROJECT by the BANK will be made, solely for the benefit and protection of the
BANK, and that the BORROWER will not rely thereon.

- 35 -

 

8.2 Indemnification by the BORROWER. The BORROWER shall bear all loss, expense (including
reasonable attorneys’ fees) and damage in connection with, and agrees to indemnify and hold
harmless the BANK, its agents, servants and employees from, all claims, demands and judgments made
or recovered against the BANK, its agents, servants and employees, because of bodily injuries,
including death at any time resulting there from, and/or because of damages to property (including
loss of use) from any cause whatsoever, arising out of, incidental to, or in connection with the
construction of the PROJECT, whether or not due to any act of omission or commission, including
negligence of the BORROWER or the GENERAL CONTRACTOR or of his or their employees, servants or
agents, other than gross negligence or willful misconduct of BANK or its agents. The BORROWER’s
liability hereunder shall not be limited to the extent of insurance carried by or provided by the
BORROWER or subject to any exclusion from coverage in any insurance policy. The obligations of the
BORROWER under this Section shall survive the payment of the CONSTRUCTION NOTE.

8.3 No Waiver; Cumulative Remedies. No failure or delay on the part of the BANK in
exercising any right, power or remedy under the LOAN DOCUMENTS shall operate as a waiver thereof;
nor shall any single or partial exercise of any such right, power or remedy preclude any other or
further exercise thereof or the exercise of any other right, power or remedy under the LOAN
DOCUMENTS. The remedies provided in the LOAN DOCUMENTS are cumulative and not exclusive of any
remedies provided by law.

8.4 Amendments, Etc. No amendment, modification, termination or waiver of any provision of
any of the LOAN DOCUMENTS or consent to any departure by the BORROWER therefrom shall be effective
unless the same shall be in writing and signed by the BANK and the BORROWER, and then such waiver
or consent shall be effective only in the specific instance and for the specific purpose for which
given. No notice to or demand on the BORROWER in any case shall entitle the BORROWER to any other
or further notice or demand in similar or other circumstances.

8.5 Addresses for Notices, Etc. Except as otherwise expressly provided herein, all
notices, requests, demands and other communications provided for under the LOAN DOCUMENTS shall be
in writing and sent by mail or telecopy (if by telecopy with a confirmation mailed within two

Exhibit 10.27

US BIO ENERGY CORPORATION

INCENTIVE STOCK OPTION AGREEMENT

2005 STOCK INCENTIVE PLAN

     THIS OPTION AGREEMENT is made as of the        day of                     , 200   , between US Bio
Energy Corporation, a South Dakota corporation (the “Company”), and                                                             , an
employee of the Company (the “Optionee”).

     The Company desires, by affording the Optionee an opportunity to purchase shares of its Common
Stock, $.01 par value per share (the “Common Stock”), as hereinafter provided, to carry out the
purposes of the US Bio Energy Corporation 2005 Stock Incentive Plan (the “Plan”).

     THEREFORE, the parties hereby agree as follows:

     1. Grant of Option. The Company hereby grants to the Optionee the right and option
(hereinafter called the “Option”) to purchase from the Company all or any part of an aggregate
amount of                                                                       
         shares of the Common Stock (the “Shares”) on the terms and
conditions herein set forth. The Option is intended to be an “incentive stock option” within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended; however, to the extent
that the Option does not so qualify with respect to the Optionee, then the Company shall treat this
option as not so qualified and this Agreement shall represent a non-qualified option.

     2. Purchase Price. The purchase price of the Shares shall be $                     per share.

     3. Term of Option. The term of the Option shall expire on                                         , subject
to earlier termination as hereinafter provided.

     4. Exercise of Option. Subject to the terms and conditions hereof, the Option shall
vest at a rate of 20% of number of Shares included in the Option annually on each of the first five
anniversaries of this Agreement; provided that, the Option shall not vest if, at
anniversary date in question, the Optionee is not employed by the Company and has not been
continuously so employed since the date of the Agreement. Further, if the Company shall file a
registration statement with the Securities and Exchange Commission with respect to an initial
public offering of its common stock, the Option shall not be exercisable from such filing date
until that date which is 180 days after the effectiveness of such registration statement or earlier
withdrawal of such registration statement, subject to acceleration of exercisability by the Board
in its discretion

     5. Acceleration of Benefits. Upon the occurrence of a Change in Control, the Option
shall automatically vest as of the date of the Change in Control, without action required on the
part of the Board or the board of directors of the surviving entity and notwithstanding any
provision of Section 4 to the contrary.

 

 

     6. Non-Transferability. The Option shall not be transferable other than by will or
the laws of descent and distribution. The Option may be exercised, during the lifetime of the
Optionee, only by the Optionee.

     7. Termination of Employment.

	 	(a)	 	Termination by Disability; Retirement; Other than Cause. If the
Optionee’s employment with the Company terminates by reason of Disability or Retirement
or for any other reason other than for Cause, the Option may be exercised, to the
extent that the Optionee shall have been entitled to do so at the date of Optionee’s
termination of employment, by the Optionee or the Optionee’s legal representative, but
may not be exercised after three (3) months from the date of the Optionee’s termination
of employment or the expiration of the term of the Option, whichever is shorter.

	 	(b)	 	Termination by Death. If the Optionee’s employment with the Company
terminates by reason of death of the Optionee, the Option may be exercised, to the
extent the Optionee shall have been entitled to do so at the date of death, but may not
be exercised after a period of one (1) year after the date of death or the expiration
of the term of the Option, whichever is shorter. In such event, the Option shall be
exercisable only by the executors or administrators of the Optionee or by the person or
persons to whom the Optionee’s rights under the option shall pass by the Optionee’ s
will or the laws of descent and distribution.

	 	(c)	 	Termination for Cause. Notwithstanding the above, in the event the
Optionee’s employment is terminated for Cause, all unexercised Options shall
immediately terminate.

     8. Method of Exercising Option. Subject to exercise limitations imposed by the
Company, including the limitation set forth in Section 4 above, Options may be exercised in whole
or in part at any time during the term of the Option by giving written notice of exercise to the
Company specifying the number of Shares to be purchased. Such notice shall be accompanied by
payment in full of the purchase price, either by certified or bank check, or by any other form of
legal consideration deemed sufficient by the Committee and consistent with the Plan’s purpose and
applicable law, including promissory notes or a properly executed exercise notice together with
irrevocable instructions to a broker acceptable to the Company to promptly deliver to the Company
the amount of sale or loan proceeds to pay the exercise price. No Shares shall be issued until
full payment therefor has been made.

     9. Investment Certificate. Prior to the receipt of the Shares pursuant to the
exercise of the Option granted hereunder, the Optionee shall, if required in the Company’s
discretion, demonstrate an intent to hold the Shares for investment and not with a view to resale
or distribution thereof to the public, by delivering to the Company an investment certificate or
letter in such form as the Company may require.

2

 

     10. Withholding Requirements. Upon exercise of the Option by the Optionee and prior
to the delivery of the Shares purchased pursuant to such exercise, the Company shall have the right
to require the Optionee to remit to the Company cash in an amount sufficient to satisfy applicable
federal and state tax withholding requirements. The Company shall inform the Optionee as to
whether it will require the Optionee to remit cash for withholding taxes in accordance with the
preceding sentence within two (2) business days after receiving from the Optionee notice that such
Optionee intends to exercise, or has exercised, all or a portion of the Option.

     11. Notice of Disqualifying Disposition. If the Optionee sells or otherwise disposes
of any of the Shares acquired pursuant to this Option on or before two years from the date of grant
or one year following the exercise of the Option, the Optionee shall immediately notify the Company
in writing of such disposition. The Company shall have the right to require the Optionee to remit
to the Company an amount sufficient to satisfy any withholding requirements.

     12. The Plan. This Option is in all respects subject to and governed by all of the
provisions of the Option Plan. A copy of the Plan is on file with the Secretary of the Company and
by acceptance hereof Optionee agrees to and accepts this Option subject to the terms of the Plan.

     13. Status. Neither the Optionee nor the Optionee’s executor, administrator, heirs,
or legatees (each a “permitted transferee”) shall be or have any rights or privileges of a
shareholder of the Company in respect of the Shares issuable upon exercise of the Option granted
hereunder, unless and until certificates representing such Shares shall be issued and delivered
and, if applicable, the permitted transferee has caused the permitted transferee’s name to be
entered as the shareholder of record on the books of the Company.

     14. Company Authority. The existence of the Option herein granted shall not affect in
any way the right or power of the Company or its stockholders to make or authorize any or all
adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure
or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures,
additional Common Stock, preferred or prior preference stock ahead of or affecting the Common Stock
of the Company or the rights thereof, or dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise. The Optionee hereby acknowledges that the Optionee’s
equity interest in the Company is subject to potential dilution.

     15. Authority. The authority to control and manage the operation and administration
of this Option shall be vested in Committee and the Committee shall have all powers with respect to
this Option as it has with respect to the Option Plan. Any interpretation of the Option by the
Board of Directors or the Committee and any decision made by it with respect to the Option shall be
final and binding.

     16. Binding Effect. This Agreement shall be binding upon the heirs, executors,
administrators and successors of the parties hereto.

     17. Capitalized Terms. All capitalized terms not otherwise defined herein shall have
the same meaning such term is given in the Plan.

     IN WITNESS WHEREOF, the Company and the Optionee have executed this Agreement as of the date
first above written.
