Aventine Renewable Energy Holdings, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

(1)           Basis of Reporting for Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements include the accounts of Aventine Renewable Energy Holdings, Inc. and its subsidiaries, which are collectively referred to as “Aventine”,  the “Company”, “we”, “our” or “us”, unless the context otherwise requires.  All significant intercompany transactions have been eliminated in consolidation.

We have prepared the unaudited condensed consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission.  Certain information and footnote disclosures normally included in statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to make the information presented not misleading.  These financial statements should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2006.

The accompanying condensed consolidated financial statements presented herewith reflect all adjustments (consisting of only normal and recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the results of operations for the three and six month periods ended June 30, 2007 and 2006.  The results of operations for interim periods are not necessarily indicative of results to be expected for an entire year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ materially from those estimates.

As of June 30, 2007, the Company’s Summary of Critical Accounting Policies for the year ended December 31, 2006, which are detailed in the Company’s Annual Report on Form 10-K, have not changed from December 31, 2006, except for the adoption of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes.  See Note 12 for additional information regarding the adoption of FIN 48 by the Company.

(2)           Recent Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”), Fair Value Measurements.  SFAS 157 defines fair value, establishes a framework for measuring fair value, and expands disclosure about fair value measurements.  The statement is effective for financial statements issued for fiscal years beginning after November 15, 2007.  The Company is currently evaluating the effect that the adoption of SFAS 157 will have, if any, on its consolidated results of operations, financial position and related disclosures.

In February 2007, The FASB issued Statement of Financial Accounting Standards No. 159 (“SFAS 159”), The Fair Value Option for Financial Assets and Financial Liabilities Including an amendment of FASB Statement No. 115.  SFAS No. 159 permits a company to choose to measure many financial instruments and other items at fair value that are not currently required to be measured at fair value.  The objective is to improve financial reporting by providing a company with the opportunity to

4

mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions.  A company shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date.  SFAS No. 159 will be effective for fiscal years that begin after November 15, 2007.  We are currently assessing the impact SFAS No. 159 will have on our consolidated financial statements.

(3)Short-Term Securities

We from time to time invest a portion of our cash in tax-free municipal auction rate certificates which generally have contractual maturities of greater than 20 years.  We consider these certificates as held for sale.  These certificates are widely traded in the public markets and may be sold as needed.  The interest rates on these certificates reprice every 35 days to the then current market rate.  Generally, the carrying value of these securities approximates the market value, and there is no gain or loss expected from changes in market value.

(4)           Inventories

Inventories are as follows:

(In thousands)	June 30, 2007		December 31, 2006
Finished products	$	67,228	$	61,775
Work-in-process	2,408		1,106
Raw materials	3,093		2,070

(5)           Prepaid Expenses and Other

Prepaid expenses and other are as follows:

(In thousands)	June 30, 2007		December 31,  2006
Fair value of derivative instruments	$	2,521	$	1,503
Prepaid insurance	1,537		1,280
Deferred income taxes current	981		1,064
Other prepaid expenses	782		702
Totals	$	5,821	$	4,549

(6)           Other Assets

Other assets are as follows:

(In thousands)	June 30,  2007		December 31, 2006
Deferred debt issuance costs	$	7,991	$	—
Investment in marketing alliances	6,000		6,000
Totals	$	13,991	$	6,000

5

Deferred debt issuance costs are subject to amortization.  Remaining deferred debt issuance costs of $7.1 million related to our 10% senior unsecured notes will be amortized utilizing a method which approximates the effective interest method over the remaining life of 10 years, resulting in amortization expense of $0.4 million over the remaining six months of 2007, and $0.7 million yearly thereafter.  Remaining deferred debt issuance costs of $0.9 million related to our secured revolving credit facility will be amortized utilizing a method which approximates the effective interest method over the five year remaining life, resulting in amortization expense of $0.1 million over the remaining six months of 2007, and $0.2 million in each of the next four succeeding years beginning in 2008.

(7)           Debt

The following table summarizes long-term debt:

(In thousands)	June 30,  2007		December 31, 2006
Senior unsecured 10% notes due April 2017	$	300,000	$	—
Secured revolving credit facility	—		—
	300,000		—
Less short-term borrowings	—		—
Total	$	300,000	$	—

Liquidity Facility

In March 2007, we entered into a new secured revolving credit facility with JPMorgan Chase Bank, N.A. of up to $200 million, subject to collateral availability, which, under certain circumstances, can be increased up to $300 million.  We had no borrowings outstanding under our secured revolving credit facility at June 30, 2007, and $1.2 million of standby letters of credit outstanding, leaving approximately $70.8 million in additional borrowing availability under our secured revolving credit facility as of that date.  As of December 31, 2006, we had no borrowings outstanding under our previous secured revolving credit facility and $4.0 million of standby letters of credit outstanding, leaving approximately $26.0 million in additional borrowing availability under the previous secured revolving credit facility as of that date.

A fixed asset component in an amount of $50 million may be added to the borrowing base on or prior to December 31, 2007 upon the satisfaction of certain requirements.  We are in the process of satisfying the requirements necessary in order to take advantage of this fixed asset component.

Senior Notes

In March 2007, we issued $300 million aggregate principal amount of senior unsecured 10% fixed-rate notes due April 2017 (“Notes”).  Our Notes were issued pursuant to an indenture, dated as of March 27, 2007, between us and Wells Fargo Bank, N.A., as trustee.  The Notes are general unsecured obligations of the Company and certain of its guarantor subsidiaries, initially limited to $300 million aggregate principal amount.  We may, subject to the covenants and applicable law, issue additional notes under the indenture.  Any additional Notes would be treated as a single class with the previously issued Notes for all purposes under the indenture.

Our Notes have interest payments due semi-annually on April 1 and October 1 of each year, and are redeemable after the dates and at prices (expressed in percentages of principal amount on the redemption date), as set forth below:

6

Year	Percentage
April 1, 2012	105.000%
April 1, 2013	103.330%
April 1, 2014	101.667%
April 1, 2015 and thereafter	100.000%

In addition, at any time prior to April 1, 2010, we may redeem up to 35% of the principal amount of the Notes from time to time originally issued with the net cash proceeds of one or more sales of qualifying capital stock of the Company at a redemption price of 100% of the principal amount, together with accrued and unpaid interest to the redemption date, provided that at least 65% of the aggregate principal amount of the Notes originally issued remains outstanding immediately after such redemption and notice of any such redemption is mailed within 60 days of each such sale of capital stock.

We have registered the Notes through a shelf registration statement in accordance with a registration rights agreement.  The shelf registration statement was declared effective on July 12, 2007.  We are currently conducting an exchange offer to exchange the Notes for an issue of registered unsecured senior notes, with terms identical to the Notes.  If by October 23, 2007 we have not consummated a registered exchange offer for the Notes, the annual interest rate on the Notes will increase by 0.25% and by 0.25% for each subsequent 90 day period, up to a maximum 1.00% over the stated fixed rate of the Notes.

(8)           Other Long-Term Liabilities

Other long-term liabilities are as follows:

(In thousands)	June 30, 2007		December 31, 2006
Reserve for uncertain tax positions (See Note 12)	$	8,991	$	—
Accrued interest on Uncertain tax positions (See Note 12)	701		—
Accrued pension and postretirement	2,181		2,427
Unearned commissions	1,766		1,977
Totals	$	13,639	$	4,404

(9)           Stock-Based Compensation Plans

The Company values its share-based payment awards using a form of the Black-Scholes option-pricing model (the “option-pricing model”).  The determination of fair value of share-based payment awards on the date of grant using this option-pricing model is affected by our stock price as well as the input of other subjective assumptions.  The option-pricing model requires a number of assumptions, of which the most significant are, expected stock price volatility, the expected pre-vesting forfeiture rate and the expected option term (the amount of time from the grant date until the options are exercised or expire).  Expected volatility is normally calculated based upon actual historical stock price movements over the expected option term.  Since we have no long-term history of stock price volatility as a public company, we calculate volatility by considering, among other things, the expected volatilities of public companies engaged in similar industries.  Pre-vesting forfeitures are estimated using a 3% forfeiture rate.  The expected option term is calculated using the “simplified” method permitted by SAB 107.  Our options have characteristics significantly different from those of traded options, and changes in the assumptions can materially affect the fair value estimates.

7

Beginning in 2007, the Company commenced an ongoing long-term incentive program under the Aventine Renewable Energy Holdings, Inc. 2003 Stock Incentive Plan, as amended (the “Plan”).  It is anticipated that this program will provide regular annual grants of performance shares.  Performance shares are stock units that will be converted to common shares, to the extent earned, at the end of a three-year performance cycle.  The first performance cycle began on January 1, 2007, and will end on December 31, 2009.  Under the performance share program, each participant is given a target award expressed as a number of shares, with a payout opportunity ranging from 0% to 150% of the target, depending on the performance relative to pre-determined goals.  The performance goals for the January 1, 2007 to December 31, 2009 performance cycle relate to the growth of the Company as measured by actual equity gallons produced.  On May 25, 2007, the Company issued 94,500 performance shares at the target award level to various participants under the Plan.  Under FAS 123R, an accounting estimate of the number of these shares that are expected to vest has been made and are being expensed utilizing the grant-date fair value of the shares from the date of grant through the end of the performance cycle period.  Any future changes to the estimate will be reflected in stock-based compensation expense in the period the estimate change is made.

Pre-tax stock-based compensation expense for the three month period ended June 30, 2007 was $1.8 million, of which $0.1 million was charged to cost of goods sold and $1.7 million was charged to selling, general and administrative expense.  This expense reduced earnings per share by $0.03 per basic and diluted share for the quarter ended June 30, 2007.  For the three month period ended June 30, 2006, pre-tax stock-based compensation expense was $1.7 million, all of which was charged to selling, general and administrative expense.  This expense reduced earnings per share by $0.05 per basic and diluted share for the quarter ended June 30, 2006.  For the six month period ended June 30, 2007, pre-tax stock-based compensation expense was $3.4 million, of which $0.1 million was charged to cost of goods sold and $3.3 million was charged to selling, general and administrative expense.  This expense reduced earnings per share for the six month period ended June 30, 2007 by $0.05 per basic and diluted share.   For the six month period ended June 30, 2006, pre-tax stock-based compensation expense was $3.0 million, all of which was charged to selling, general and administrative expense.  This expense reduced earnings per share for the six month period ended June 30, 2006 by $0.09 per basic share and $0.08 per diluted share.  The Company recognized a tax benefit on its condensed consolidated statement of income from stock-based compensation expense in the amount of $0.5 million and $0.7 million for the three month periods ended June 30, 2007 and 2006, respectively, and in the amount of $1.0 million and $1.2 million for the six month periods ended June 30, 2007 and 2006, respectively.  The Company recorded pre-tax stock-based compensation expense for the three and six month periods ended June 30, 2007 and 2006 as follows:

	Three months ended June 30,				Six months ended June 30,
(in millions)	2007		2006		2007		2006

Total	$	22.0	7.0	$	23.3	3.4

The Company granted stock options during the quarters ended June 30, 2007 and 2006.  The determination of the fair value of the stock option awards, using the option-pricing model, incorporated the assumptions in the following table for stock options granted during the three month periods ended June 30, 2007 and 2006.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant over the expected term.  Expected volatility is calculated by considering, among other things, the expected volatilities of public companies engaged in similar industries.  The expected option term is calculated using the “simplified” method permitted by SAB 107.  Assumptions for options granted in the three month period ending June 30, 2007 and 2006 are as follows:

	2007			2006
Expected stock price volatility	58.0		%	58.0		%
Expected life (in years)	6.5			6.5
Risk-free interest rate	4.9		%	4.9		%
Expected dividend yield	0.0		%	0.0		%
Weighted average fair value	$	10.57		$	13.77

(12)         Income Taxes

The Company lowered its estimated annual tax rate for 2007 during the second quarter to adjust its income tax rate for the six month period ending June 30, 2007 to 32.5%, which is the rate we now estimate we will incur for 2007.  This was done to reflect both a higher level of tax exempt interest

11

income from investments and from a lower level of pre-tax income as compared to our first quarter of 2007 estimate.  This year to date true-up reduced the second quarter 2007 income tax expense by $0.6 million.  This change in estimate increased second quarter 2007 basic and diluted earnings per share by $0.02 per share.

In July 2006, the FASB issued FIN 48.  This interpretation clarified the accounting for uncertainty in income taxes recognized in the financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes.  FIN 48 prescribes a recognition threshold and measurement of a tax position taken or expected to be taken in a tax return.  This interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, and disclosure.

We adopted the provisions of FIN 48 on January 1, 2007.  As a result of the adoption, we recognized a $0.7 million decrease in our reserves for uncertain tax positions and a $0.5 million increase in accrued interest on uncertain tax positions, resulting in a net $0.2 million increase in retained earnings.  We also reclassified $8.1 million between deferred income taxes and other long-term liabilities to conform to the balance sheet presentation requirements of FIN 48.

As of January 1, 2007, we had $8.5 million of uncertain tax benefits.  All of our unrecognized tax benefits, if recognized in future periods, would impact the Company’s effective tax rate.  During the three and six month periods ended June 30, 2007, our liability for unrecognized tax benefits increased by $0.5 million and $0.9 million, respectively.  At June 30, 2007, our liability for unrecognized tax benefits was $9.5 million, and is included in other long-term liabilities on the condensed consolidated balance sheet.

We include interest expense or income, as well as potential penalties on unrecognized tax benefits, as a component of income tax expense in the condensed consolidated statement of operations.  The total amount of accrued interest related to uncertain tax positions at January 1, 2007 was $0.5 million, net of the deferred tax benefit, and is included in other long-term liabilities.  We increased our accrual for interest related to uncertain tax positions by $0.1 million and $0.2 million, respectively, net of the deferred tax benefit, for the three and six month periods ended June 30, 2007.  Our liability for accrued interest on unrecognized tax benefits at June 30, 2007 was $0.7 million, net of the deferred tax benefit, and is included in other long-term liabilities on the condensed consolidated balance sheet.

Our federal income tax returns for 2003 to 2006 are open tax years.  We file in numerous state jurisdictions with varying statutes of limitation open from 2002 through 2006 depending on each jurisdiction’s statute of limitation.  In 2006, the IRS commenced an examination of our U.S. income tax return.  The Company expects this examination to be concluded and settled within the next 12 months.  Based on the outcome of this examination, or as a result of the expiration of statute of limitations for specific jurisdictions, our unrecognized tax benefits for tax positions taken on previously filed tax returns possibly will materially change from the unrecognized tax benefits recorded as other long-term liabilities in our financial statements at January 1, 2007.  In addition, the outcome of these examinations may impact the valuation of certain deferred tax assets in future periods.  As a result, based on the status of these examinations, and the protocol of finalizing audits by the relevant tax authorities, which could include formal legal proceedings, it is not possible to estimate the impact of any amount of such changes, if any, to previously recorded uncertain tax positions.

(13)         Earnings Per Share

Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding during each period.  Diluted earnings per share are calculated using the

12

treasury stock method in accordance with SFAS 128, and includes the effect of all dilutive securities, including non-qualified stock options and restricted stock units (“RSU’s”).

The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended June 30,				Six months ended June 30,
(In thousands, except per share data)	2007		2006		2007		2006
Net income	$	12,607	$	24,654	$	27,547	$	36,841
Weighted average shares and share equivalents outstanding:
Basic shares	41,912		35,152		41,861		35,149
Dilutive non-qualified stock options and RSU’s	737		1,420		693		1,378
Diluted weighted average shares and share equivalents	42,649		36,572		42,554		36,527
Income per common share - basic:	$	0.30	$	0.70	$	0.66	$	1.05
Income per common share - diluted:	$	0.30	$	0.67	$	0.65	$	1.01

We had additional potential dilutive securities outstanding representing 530,000 common shares for the three month period ended June 30, 2007 that were not included in the computation of potentially dilutive securities because the options’ exercise prices were greater than the average market price of the common shares.

(14)         Industry Segment

The Company operates in one reportable business segment, the manufacture and marketing of fuel-grade ethanol.

(15)         Litigation

We are from time to time involved in various legal proceedings, including legal proceedings relating to the extensive environmental laws and regulations that apply to our facilities and operations. We are not involved in any legal proceedings that we believe could have a material adverse effect upon our business, operating results or financial condition.

(16)         Condensed Consolidating Financial Information

The following tables present condensed consolidating financial information for: (a) Aventine Renewable Energy Holdings, Inc.

Vernon, LLC; and (c) the Non-Guarantor Subsidiary, Nebraska Energy, LLC.  Each Subsidiary Guarantor is wholly-owned by Aventine Renewable Energy Holdings, Inc.  The guarantees of each of the Subsidiary Guarantors are full, unconditional, joint and several.  Accordingly, separate financial statements of the wholly-owned Subsidiary Guarantors are not presented because the Subsidiary Guarantors are jointly, severally and unconditionally liable under the guarantees, and the Company believes that separate financial statements and other disclosures regarding the Subsidiary Guarantors are not material to investors.  Furthermore,

13

there are no significant legal restrictions on the Parent’s ability to obtain funds from its subsidiaries by dividend or loan.

Company Overview

Aventine is a leading producer and marketer of ethanol.  Through our own production facilities, marketing alliances with other ethanol producers and our purchase/resale operations, we market and distribute ethanol to many of the leading energy companies in the U.S.  We have a comprehensive national distribution network utilizing trucks, a leased railcar and barge fleet and a terminal network at critical points on the nation’s transportation grid where our ethanol is blended with our customers’ gasoline.  Aventine is also a marketer and distributor of biodiesel.  In addition to producing ethanol, our facilities also produce several co-products including: corn gluten feed and meal, corn germ, condensed corn distillers solubles, dried distillers grain with solubles (“DDGS”), wet distillers grain with solubles (“WDGS”), carbon dioxide and brewers’ yeast.

Results of Operations

The following discussion summarizes the significant factors affecting the consolidated operating results of the Company for the three and six month periods ended June 30, 2007 and 2006.  This discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements contained in Item 1 above, and the consolidated financial statements and related notes for the year ended December 31, 2006 included in the Company’s Annual Report on Form 10-K.

Our revenues are principally derived from the sale of ethanol and from the sale of co-products (corn gluten feed and meal, corn germ, condensed corn distillers solubles, DDGS, WDGS, carbon dioxide, and brewers’ yeast) that we produce as by-products during the production of ethanol at our plants, which we refer to as co-product revenues.  We sell ethanol obtained from the following sources:

17

·Ethanol we manufacture at our plants;

·Ethanol we purchase from our marketing alliance partners; and

·Ethanol we purchase on the spot market.

We market and sell ethanol without regard to whether we produced it, are marketing it for our marketing alliance partners or purchased it on the spot market for resale.  In addition to ethanol, we also purchase and market biodiesel.

Executive Summary

We generated net income of $12.6 million, or $0.30 per diluted share in the second quarter of 2007, as compared to net income of $24.7 million, or $0.67 per diluted share, in the second quarter of 2006.  Net income decreased primarily as a result of significantly higher corn costs combined with lower ethanol revenue per gallon sold.  Second quarter 2006 results benefited from the sale of 10.5 million gallons of ethanol from inventory at prices significantly higher than their first quarter 2006 weighted average cost of $1.58 per gallon, increasing gross profit in the second quarter of 2006 by approximately $18.6 million.  In addition, higher selling, general and administrative expenses, including costs associated with being a public company and from the expansion and growth of our business, also attributed to the decline in net earnings.  Revenue in the second quarter of 2007 was $394.9 million, a decrease of $48.0 million, or 10.8%, over second quarter 2006 revenue of $442.9 million.  The decrease is mainly the result of a decrease in gallons sold, as VeraSun Energy Corporation was no longer part of our marketing alliance, along with a reduction in the average price per gallon of ethanol sold.  The average sales price per gallon of ethanol in the second quarter of 2007 was $2.29 per gallon, down from $2.41 per gallon in the same quarter in 2006.

Gallons of ethanol sold in the second quarter of 2007 decreased 10.0% to 158.7 million gallons, as compared to 176.3 million gallons in the second quarter of 2006.  Ethanol sales for the quarter decreased as a result of lower marketing alliance purchases due to a former alliance member leaving our marketing alliance on April 1, 2007.  The lower number of marketing alliance gallons purchased was offset somewhat by increased equity production.  Ethanol production in the quarter totaled 50.7 million gallons, up from 28.9 million gallons in the second quarter of 2006.  This record production was achieved despite some operational issues at the Aurora facility.

Gross profit totaled $27.4 million in the second quarter of 2007, a decrease of $22.8 million, or 45.4%, from the second quarter of 2006.  The decline in gross profit was principally the result of a significantly lower commodity spread caused by higher corn prices and lower ethanol prices.  Our corn costs during the second quarter of 2007 averaged $3.99 per bushel, significantly higher than our second quarter 2006 cost of $2.27 per bushel.

The average cost of inventory was $1.98 at the end of the second quarter of 2007 as compared to $1.91 at the end of the first quarter of 2007.  The average cost per gallon of ethanol purchased in the second quarter of 2007 was higher than in the first quarter of 2007.  This means that the lower per gallon value of ethanol in inventory at the end of the first quarter of 2007 positively impacted gross margin during the second quarter by $2.1 million.  This compares with the same issue positively impacting gross margin in the second quarter of 2006 by approximately $18.6 million, as the second quarter 2006 average

18

cost of inventory was $2.19 per gallon as compared to $1.58 per gallon at the end of the first quarter of 2006.  Our inventory is valued based upon a weighted average price we pay for ethanol that we purchase from our marketing alliance partners and our purchase/resale transactions, along with our own cost to produce ethanol.  Changes, either upward or downward, in our purchased cost of ethanol or our own production costs, will cause the inventory value to fluctuate from period to period, perhaps significantly.  These changes in value flow through our statement of operations as the inventory is sold and can significantly increase or decrease our profitability.

Other non-operating income for the second quarter of 2007 includes $2.1 million of realized and unrealized gains on corn derivative contracts and from realized and unrealized losses on the sale of forward gasoline contracts.  All of our derivative hedge positions have been marked to market, and we have already recorded income or loss with respect to these positions as of June 30, 2007.  Increases in prices for open derivative contracts above the closing price at June 30, 2007 will result in mark to market losses on these positions, while prices lower than those at June 30, 2007 will allow for additional hedge gains.

For the Three Months Ended June 30, 2007 Compared to the Three Months Ended June 30, 2006

Total gallons sold in the second quarter of 2007 were 158.7 million gallons, versus 176.3 million gallons sold in the second quarter of 2006, a decrease of 17.6 million gallons or 10.0%.  Gallons sourced were as follows:

Net sales in the second quarter of 2007 decreased 10.8% from the second quarter of 2006.  Net sales were $394.9 million in the second quarter of 2007 versus $442.9 million in the second quarter of 2006.  Overall, the decrease in net sales was a combination of a decrease in the number of gallons sold and a decrease in the average sales price of ethanol.  Gallons sold in the second quarter of 2007 declined as a result of a lower number of gallons that were purchased from marketing alliance partners as a result of the departure of a marketing alliance partner from our alliance on April 1, 2007.  The average gross selling price of ethanol in the second quarter of 2007 was $2.29 per gallon, down from the $2.41 received in the second quarter of 2006.

Co-product revenue for the second quarter of 2007 totaled $23.2 million, an increase of $11.5 million or 98.3%, from the second quarter 2006 total of $11.7 million.  Co-product revenue increased during the second quarter of 2007 principally from an increase in co-product tonnage sold as a result of the DDGS produced from the new Pekin dry mill production, along with higher average selling prices.  In the second quarter of 2007, we sold 297.1 thousand tons, versus 200.4 thousand tons in the second quarter of 2006.  Co-product returns, as a percentage of the price of corn, were 31.1% during the second quarter of 2007, versus 46.2% in the second quarter of 2006.  Co-product returns, as a percentage of the price of corn, decreased in the second quarter of 2007 as compared to 2006 as the result of the mix of co-products produced, with the addition of the new Pekin dry mill, and as a result of co-product pricing not keeping pace with the year over year increase in the price of corn.  Due to the addition of the new dry

19

mill in Pekin, the increase in DDGS production increased the percentage of the lower value DDGS to the overall mix of available co-products.

Cost of goods sold for the quarter ended June 30, 2007 was $367.5 million, compared to $392.7 million for the quarter ended June 30, 2006, a decrease of $25.2 million or 6.4%.  Cost of goods sold consists of the cost to produce ethanol at our own facilities, the cost of purchasing ethanol from our marketing alliance partners and from unaffiliated producers and marketers, freight and logistics costs and the cost of motor fuel taxes which have been billed to customers.  The decrease in cost of goods sold is principally the result of the reduced number of ethanol gallons purchased from marketing alliance partners, offset by higher purchased ethanol costs, and higher corn and production costs.

Purchased ethanol in the second quarter of 2007 totaled $207.9 million, versus $314.5 million in the second quarter of 2006.  The decrease in purchased ethanol results from both a decrease in the number of gallons of ethanol purchased, and by decreases in the cost per gallon of ethanol purchased.  In the second quarter of 2007, we purchased 97.2 million gallons of ethanol at an average cost of $2.14 per gallon as compared to 136.9 million gallons of ethanol at an average cost of $2.30 in the second quarter of 2006.

Production costs include corn costs, conversion costs (defined as the cost of converting the corn into ethanol, and includes production salaries, wages and stock compensation costs, fringe benefits, utilities (including coal and natural gas), maintenance, denaturant, insurance, materials and supplies and other miscellaneous production costs) and depreciation and amortization.  Corn costs in the second quarter of 2007 totaled $74.7 million or $3.99 per bushel, versus $25.3 million, or $2.27 per bushel in the second quarter of 2006.  The increase in corn costs is principally the result of a perceived increased demand by the marketplace as a result of expected new ethanol production facilities being built.  Conversion costs for the second quarter of 2007 increased to $30.9 million from $22.9 million for the second quarter of 2006.  The total dollars spent on conversion costs increased year over year as a result of the new Pekin dry mill production.  However, the conversion cost per gallon declined year over year to $0.61 per gallon in the second quarter of 2007 versus $0.79 per gallon in the second quarter of 2006.  Conversion costs per gallon in the second quarter of 2006 were negatively affected by lower production caused by maintenance outages at both production facilities along with production issues at the Aurora, Nebraska facility.

Depreciation in the second quarter of 2007 totaled $3.0 million, versus $1.1 million in the second quarter of 2006.  The increase in depreciation expense is the result of the new Pekin dry mill beginning production.  Motor fuel taxes were $4.3 million in the second quarter of 2007 versus $4.0 million in the second quarter of 2006.  The cost of motor fuel taxes are recovered through billings to customers.

Freight/logistics costs in the second quarter of 2007 decreased to $28.0 million, or approximately $0.18 per gallon, from $29.6 million, or $0.17 per gallon in the second quarter of 2006.  Freight/logistics cost per gallon is calculated by taking total freight/logistics costs incurred and dividing by the total ethanol gallons sold.  Total freight/logistics costs may also include costs to ship co-products.  The increase in freight/logistics cost per gallon is principally the result of a reduced number of gallon shipped over which to spread fixed costs, and from the expansion of our distribution system footprint.

The average cost of inventory was $1.98 at the end of the second quarter of 2007 as compared to $1.91 at the end of the first quarter of 2007. The average cost per gallon of ethanol purchased in the second quarter was higher than in the first quarter.  This means that the lower per gallon value of ethanol in inventory at the end of the first quarter positively impacted gross margin during the second quarter by $2.1 million.  In 2006, the average cost of inventory was $2.19 at the end of the second quarter as compared to $1.58 at the end of the first quarter of 2006.  Because the average cost per gallon of ethanol

20

purchased in the second quarter of 2006 was higher than in the first quarter of 2006, the lower per gallon value of ethanol in inventory at the end of the first quarter positively impacted gross margin during the second quarter by approximately $18.6 million.

Selling, general and administrative expenses (“SG&A”) expenses were $8.8 million in the second quarter of 2007, compared to $7.4 million in the second quarter of 2006.  The increase in SG&A expenses include increased costs related to being a public company, and from costs associated with the expansion and growth of our business.  Year over year increases reflect increased expenditures for legal and other professional fees associated with our being a public company, including increased legal fees related to our capacity expansion efforts, the costs of complying with Section 404 of Sarbanes-Oxley Act of 2002, higher insurance costs related to directors and officers insurance, and increased IT costs.

Interest income in the second quarter of 2007 was $4.2 million, versus $1.2 million in the second quarter of 2006.  The increase in interest income is due to a combination of a higher average level of funds available to invest as a result of our recent note offering and funds from last year’s initial public offering, combined with higher short-term investment rates due to increases in interest rates in general.

Interest expense in the second quarter of 2007 was $7.0 million, as compared to $4.2 million in the second quarter of 2006.  Interest expense in the second quarter of 2007 increased due to the issuance in March 2007 of $300 million aggregate principal amount of 10.0% senior unsecured notes.  In the second quarter of 2006, we had outstanding a previous issue of $160 million aggregate principal amount of floating rate senior secured notes, the majority of which was repurchased in July 2006.

The minority interest for the quarter ended June 30, 2007 was a $0.7 million charge to income compared to $1.7 million charge to income for the quarter ended June 30, 2006.  This decrease reflects the reduced operating performance of our Nebraska subsidiary caused primarily by the year over year significant increase in corn costs and the lower average price received per gallon in the second quarter of 2007 from the sale of ethanol.

Other non-operating income for the second quarter of 2007 includes $2.1 million of realized and unrealized gains on corn derivative contracts and from realized and unrealized losses on the sale of forward gasoline contracts.  These include the effect of marking to market these contracts at quarter end.  For the second quarter of 2006, net realized and unrealized gains of $1.9 million were recorded on corn derivative contracts.  Other non-operating income is impacted by the CBOT prices for derivative contracts.

The income tax rate for the second quarter of 2007 was 28.9% versus a rate of 39.1% in the second quarter of 2006.  The lower rate in the second quarter of 2007 resulted from lower state rates now being accrued as compared to the second quarter of 2006, along with adjusting our estimated tax provision for the second quarter of 2007 to reflect both a higher level of tax exempt interest income from investments and from a lower level of pre-tax income as compared to our first quarter of 2007 estimate.  The true-up in the second quarter of 2007 adjusts our year to date 2007 rate to 32.5%, which is what we now estimate we will incur for 2007.  Income tax expense for the second quarter of 2007 also includes a component for interest expense related to uncertain tax positions in accordance with FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109.

For the Six Months Ended June 30, 2007 Compared to the Six Months Ended June 30, 2006

Total gallons sold in the first six months of 2007 were 351.9 million gallons, versus 341.1 million gallons sold in the first six months of 2006, an increase of 10.8 million gallons or 3.2%.  Gallons sourced were as follows:

Net sales in the first half of 2007 increased 9.9% from the first half of 2006.  Net sales were $831.6 million in the first half of 2007 versus $756.4 million in the first half of 2006.  Overall, the increase in net sales was a combination of the increase in the number of gallons sold and the increase in the average sales price of ethanol.  Gallons sold in the first six months of 2007 increased as a result of a higher equity production and a higher number of gallons purchased from non-affiliated producers offset by the lower number of gallons that were purchased from marketing alliance partners as a result of a marketing alliance partner who left our marketing alliance as of April 1, 2007.  The average gross selling price of ethanol in the first half of 2007 increased to $2.18 per gallon, from the $2.11 received in the first half of 2006.

Co-product revenue for the first six months of 2007 totaled $46.3 million, an increase of $19.8 million or 74.7%, from the first six month 2006 total of $26.5 million.  Co-product revenue increased during the first six months of 2007 versus 2006 principally from an increase in co-product tonnage sold as a result of the DDGS produced from the new dry mill production and production issues in 2006, along with higher average selling prices.  In the first six months of 2007, we sold 564.1 thousand tons, versus 448.8 thousand tons in the first six months of 2006.  Co-product returns, as a percentage of the price of corn, were 33.2% during the first half of 2007, versus 48.1% in the first half of 2006.  Co-product returns, as a percentage of the price of corn, decreased in the first half of 2007 as compared to 2006 as the result of increases in the price of corn continuing to outpace the increase in co-product pricing, and from the mix of co-products produced.  Due to the addition of the new dry mill in Pekin, the increase in DDGS production increased the percentage of the lower value DDGS to the overall mix of available co-products.

Cost of goods sold for the first six months of 2007 was $775.7 million, compared to $675.6 million for the first six months of 2006, an increase of $100.1 million or 14.8%.  Cost of goods sold consists of the cost to produce ethanol at our own facilities, the cost of purchasing ethanol from our marketing alliance partners and from unaffiliated producers and marketers, freight and logistics costs and the cost of motor fuel taxes which have been billed to customers.  The increase in cost of goods sold is principally the result of the increased number of ethanol gallons purchased from non-affiliated producers and marketers, and from higher purchased ethanol costs and higher corn and production costs.

Purchased ethanol in the first half of 2007 totaled $508.7 million, versus $536.2 million in the first six months of 2006.  The decrease in purchased ethanol results from a decrease in the number of gallons of ethanol purchased, offset by an increase in the cost per gallon of ethanol purchased.  In the first half of 2007, we purchased 253.4 million gallons of ethanol at an average cost of $2.01 per gallon as compared to 271.9 million gallons of ethanol at an average cost of $1.97 in the first half of 2006.

Production costs include corn costs, conversion costs (defined as the cost of converting the corn into ethanol, and includes production salaries, wages and stock compensation costs, fringe benefits, utilities (including coal and natural gas), maintenance, denaturant, insurance, materials and supplies and

22

other miscellaneous production costs) and depreciation and amortization.  Corn costs in the first half of 2007 totaled $139.4 million or $3.79 per bushel, versus $54.5 million, or $2.19 per bushel in the first half of 2006.  The increase in corn costs is principally the result of a perceived increased demand by the marketplace as a result of expected new ethanol production facilities being built.  Conversion costs for the first half of 2007 increased to $57.9 million from $43.5 million for the first half of 2006.  The total dollars spent on conversion costs increased year over year as a result of the new Pekin dry mill production.  However, the conversion cost per gallon declined year over year to $0.58 per gallon in the first half of 2007 versus $0.66 per gallon in the first half of 2006.  Conversion costs per gallon in the first half of 2006 were negatively affected by lower production caused by maintenance outages at both production facilities along with production issues at the Aurora, Nebraska facility.

Depreciation in the first half of 2007 totaled $6.0 million, versus $2.1 million in the first half of 2006.  The increase in depreciation expense is the result of the new Pekin dry mill beginning production.  Motor fuel taxes were $10.5 million in the first half of 2007 versus $5.6 million in the first half of 2006.  The cost of motor fuel taxes are recovered through billings to customers.

Freight/logistics costs in the first half of 2007 increased to $58.2 million, or approximately $0.17 per gallon, from $52.0 million, or $0.15 per gallon in the first half of 2006.  The increase in freight/logistics cost is principally the result of a reduced number of gallons shipped over which to spread fixed costs, and from the expansion of our distribution system footprint.

The average cost of inventory was $2.19 at the end of the second quarter of 2006 as compared to $1.58 at the end of the first quarter of 2006. The average cost per gallon of ethanol purchased in the second quarter was higher than in the first quarter.  This means that the lower per gallon value of ethanol in inventory at the end of the first quarter positively impacted gross margin during the second quarter by approximately $18.6 million.

SG&A expenses were $18.4 million in the first half of 2007, compared to $13.6 million in the first half of 2006.  SG&A expenses increased as a result of increased costs related to being a public company, and from costs associated with the expansion and growth of our business.  Year over year increases in SG&A costs are primarily due to increased costs related to legal and other professional fees associated with our being a public company, including increased legal fees related to our capacity expansion efforts, the costs of complying with Section 404 of Sarbanes-Oxley Act of 2002, higher insurance costs related to directors and officers insurance, and increased IT costs.

Interest income in the first half of 2007 was $5.5 million, versus $1.9 million in the first half of 2006.  The increase in interest income is due to a combination of a higher average level of funds available to invest as a result of our March 2007 note offering and funds from last year’s initial public offering, combined with higher short-term investment rates due to increases in interest rates in general.

Interest expense in the first half of 2007 was $7.4 million, as compared to $8.6 million in the first half of 2006.  Interest expense in the first half of 2007 reflects only interest incurred from March 2007 through June 2007 on our $300 million aggregate principal amount of 10.0% senior unsecured notes.  In the first half of 2006, we had outstanding a previous issue of $160 million aggregate principal amount of floating rate senior secured notes for the entire first half of 2006, the majority of which was repurchased in July 2006.

The minority interest for the first half of 2007 was a $1.2 million charge to income compared to $2.9 million charge to income for the first half of 2006.  This decrease reflects the reduced operating performance of our Nebraska subsidiary caused primarily by the year over year significant increase in

23

corn costs offset somewhat by the higher average price received per gallon in the first half of 2007 as compared to 2006 from the sale of ethanol.

Other non-operating income for the first half of 2007 of $6.0 million reflects realized and unrealized gains on corn derivative contracts and from realized and unrealized losses on the sale of forward gasoline contracts.  These include the effect of marking to market these contracts at June 30, 2007.  For the first half of 2006, we recognized $2.5 million of net realized and unrealized gains on corn derivative contracts.  Other non-operating income is impacted by the CBOT prices for derivative contracts.

Income taxes for the first half of 2007 were accrued at a rate of 32.5% versus a rate of 39.3% in the first half of 2006.  The lower rate in the first half of 2007 results from lower state rates being accrued as compared to the first half of 2006, along with a higher level of tax exempt interest income from investments and a lower level of pre-tax income as compared to our 2006 estimate.  We expect our estimated tax rate for 2007 to be approximately 32.5%.  Income tax expense for the first six months of 2007 also includes a component for interest expense related to uncertain tax positions in accordance with FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109.

Trends and Factors that May Affect Future Operating Results

Ethanol Pricing

As of June 30, 2007, we had contracts for delivery of ethanol totaling 161.7 million gallons for delivery throughout the remainder of 2007, which represents approximately 57% of our expected ethanol shipments for the remainder of the year.  These commitments were for 20.7 million gallons at an average  fixed price of $2.05, 49.7 million gallons at an average positive spread to wholesale gasoline of $0.03 (based upon the NYMEX, Chicago and NY harbor indices), and 91.3 million gallons at spot prices (using various Platt, OPIS and AXXIS indices).  Although these contracts are for delivery throughout 2007, they are heavily weighted towards the third quarter of 2007.  In the second quarter of 2007, we also took short gasoline positions through swap agreements where we sold 15.2 million gallons of gasoline at a fixed price of $1.96 per gallon for delivery from August 2007 through January 2008.  We did this to hedge some of our gas plus contracts from potentially falling gasoline prices.  The mark to market value of these positions at June 30, 2007 was a loss of approximately $1.5 million.

Corn Pricing

Based on our current hedges and current market conditions, we estimate our corn costs for the third quarter of 2007 will be in the $3.75 to $3.85 per bushel range, and our fourth quarter 2007 corn costs will be in the $3.40 to $3.50 per bushel range, excluding any effects of mark to market adjustments on our hedge positions.  All of our corn hedge positions have been marked to market, and we have already recorded income or loss with respect to these positions as of June 30, 2007.  Increases in prices for open derivative contracts above the closing price at June 30, 2007 will result in mark to market losses on these positions, while prices lower than those at June 30, 2007 will allow for additional hedge gains.

Marketing Alliance

As of April 1, 2007, VeraSun Energy Corporation was no longer part of our marketing alliance.  During the second quarter, two new marketing alliance partner projects began ethanol production.  E3 Biofuels, with production capacity of 24 million gallons of ethanol annually, and Redfield Energy, LLC, with production capacity of 50 million gallons of ethanol annually, both began shipping product during

24

the second quarter.  As of June 30, 2007, our marketing alliance partners have nameplate capacity to produce 361 million gallons of ethanol annually.   We expect one more new plant with annual capacity of 50 million gallons to come online in 2007, along with the expansion of one existing plant to also add 50 million gallons of annual capacity.  We have also signed contracts to market an additional 1.4 billion gallons of ethanol from existing and new marketing alliance partners who have projects currently under construction, and for projects which have been proposed.  301 million gallons of this amount is currently under construction.  We believe these plants currently under construction will be completed and we expect to market these additional gallons.  These plants are expected to come online between October 2007 and December 2008.  In addition, we have also signed marketing agreements for another 1.1 billion gallons of annual capacity for proposed projects.  Construction of these proposed projects has not commenced, and there can be no assurances that these projects will be commenced or completed on a timely basis, or at all.

Supply and Demand

It is expected that annual ethanol production capacity in the U.S. will total in excess of 7.5 billion gallons annually by the end of 2007, which is the amount required by the existing renewable fuel standard for 2012.  Ethanol produced in the United States competes with sugar-based ethanol produced in Brazil.  This additional capacity, along with imports, may cause supply to exceed demand.  If additional demand for ethanol is not created, either through additions to discretionary blending (through increased penetration rates in areas that blend ethanol today or through the establishment of new markets where little or no ethanol is blended today), or through additional governmental mandates at either the federal or state level, the excess supply may cause ethanol prices to decrease, perhaps substantially.

Expansion

We have identified opportunities to increase our equity production capacity through the development of new production facilities and are continually exploring acquisition opportunities.  In addition to the 57 million gallon dry mill expansion of our Pekin, Illinois facility which was completed in early 2007, we have committed to build new ethanol production facilities at Mt. Vernon, Indiana and Aurora, Nebraska, and are exploring adding additional capacity at our existing Pekin, Illinois campus.

We intend to substantially complete 226 million gallons of capacity expansions by the end of 2008.  The timing of the remaining expansions will be based upon, among other factors, market conditions and the availability of financing on attractive terms.   On May 31, 2007, we entered into separate but substantially identical EPC contracts with a construction firm, Kiewit Energy Company (“Kiewit”), to build two initial 113 million gallon ethanol production facilities in Mount Vernon, Indiana and Aurora, Nebraska.  Delta-T Corporation is the technology provider and is a sub-contractor to Kiewit under the EPC contracts.  Under the terms of each of the EPC contracts, Kiewit will provide certain EPC materials and services necessary to build ethanol production facilities at each site capable of initially producing 113 million gallons of denatured ethanol annually as the primary product.  In addition, the EPC contracts also call for Kiewit to provide certain additional materials and services to prepare each site for a phase II expansion.  A phase II expansion would double the capacity of each of the plants, and the Company is currently seeking permits for the full 226 million gallons of annual production capacity for each site upfront.  The EPC contracts call for payments to Kiewit in the amount of $462.5 million.  Certain owner project costs are excluded from the EPC contracts.  These include, but are not limited to, the cost of land, as well as the cost of bringing power, water sewer and natural gas service to the sites.  These costs are the responsibility of Aventine.

Each of the EPC contracts also allows for credits against the contract total for amounts paid for materials and services under each of an advance work agreement entered into with Delta-T Corporation

25

in March 2007 and a pre-EPC agreement entered into with Kiewit in March 2007.  Our timetable to begin and complete these projects is subject to numerous factors beyond our control.  In particular, we have not yet received any environmental or other permits with respect to these expansions (although construction and certain other permit applications have been filed).  Accordingly, we cannot give assurance that these expansion projects will be completed on a timely basis or at all or that we will realize the benefits we anticipate.  In addition, while we expect to raise additional funds for the phase II facility additions, we cannot be sure that we will be able to obtain such additional funding for these phase II transactions on attractive terms or at all.  In addition, we may have to pay penalties or damages under certain contracts related to such capacity expansions.

Bio-Diesel

During the second quarter of 2007, we announced the addition of a major new biodiesel producer to our biodiesel marketing effort.  In the second quarter of 2007, we sold 1.9 million gallons of biodiesel.  Although this program is still in its infancy, we are adding additional resources toward its growth.

Liquidity and Capital Resources

Overview and Outlook

The following table sets forth selected information concerning our financial condition:

On May 31, 2007, we entered EPC contracts to build two initial 113 million gallon ethanol production facilities in Mount Vernon, Indiana and Aurora, Nebraska.   These EPC contracts call for payments to Kiewit in the amount of $462.5 million.  Certain owner project costs are excluded from the EPC contracts.  These include, but are not limited to, the cost of land, as well as the cost of bringing power, water sewer and natural gas service to the sites.  These costs are the responsibility of Aventine.  Each of the EPC contracts also allows for credits against the contract total for amounts paid for materials and services under each of an advance work agreement entered into with Delta-T Corporation in March 2007 and a pre-EPC agreement entered into with Kiewit in March 2007.  The EPC contracts also call for Kiewit to provide certain additional materials and services to prepare each site for a phase II expansion.  A phase II expansion would double the capacity of each of the plants, and the Company is currently seeking permits for the full 226 million gallons of annual production capacity for each site upfront.  While we expect to raise additional funds for the Aurora West and Mt. Vernon phase II facility additions as well as the Pekin III facility, we cannot be sure that we will be able to obtain such additional funding for these transactions on attractive terms or at all.

We are contractually obligated, subject to certain conditions, including obtaining necessary permits, to develop both a 113 million gallon plant adjacent to our Nebraska facility (using commercially reasonable best efforts to obtain a permit for 226 million gallon capacity) and a 226 million gallon plant in Mount Vernon, Indiana.  If we do not meet certain specified milestones, we will be subject to penalties.  The contract to complete the 226 million gallon expansion adjacent to our Nebraska facility provides for liquidated damages not exceeding $5 million if specified milestones are not met or we do

26

not construct a facility with a capacity of at least 110 million gallons.  If such penalties are not paid, the counterparty to the contract has the right to repurchase the property at cost (subject to adjustment for any expenses, which we have paid with respect to infrastructure construction).  In certain cases, the counterparty can agree to an extension and limited cure rights for payments.  The contract for completion of the 226 million gallon plant in Mount Vernon, Indiana provides that, if we do not meet certain milestones, subject to specified extension rights and cure periods, we will be in default under our lease with the Indiana Port Commission.  The State of Indiana may complete construction of the plant at our expense if we fail to do so.  The contract does not provide for liquidated damages as an alternative.  In addition, we would also be subject to certain other penalties provided for in the lease.  Notwithstanding the above, if, despite our diligent efforts, we are unable to obtain permits for the Mt. Vernon facility by September 1, 2007, we have agreed to negotiate in good faith a waiver of the compliance date and establish a new date for compliance.  If we do not reach an agreement, either the Mount Vernon lessor or we can terminate the Mount Vernon lease.  Accordingly, we cannot estimate the amount of damages we could be liable for.

With our current cash balances, amounts available under our secured revolving credit facility and anticipated cash flow from operations, we believe that we will be able to satisfy existing anticipated working capital needs, debt service obligations, capital expenditure and other anticipated cash requirements for the remainder of the year.

Sources of Liquidity

Our principal sources of liquidity are cash, short-term investments, cash provided by operations, and cash available under our secured revolving credit facility.

Cash and short-term investments.  For the first six months of 2007, cash and short-term investments increased by $257.1 million.  Cash and short-term investments as of June 30, 2007 and December 31, 2006 were $385.8 million and $128.7 million, respectively.   The increase in cash and short-term investments is principally the result of cash received from the private placement of $300 million aggregate principal amount of senior unsecured 10% fixed rate notes, net of fees, cash received from our initial public offering completed in the third quarter of 2006, and from cash provided by operations.

Cash provided by operations.  Net cash provided by operating activities in the first six months of 2007 was $45.0 million, as compared to cash provided by operating activities of $43.5 million for the first six months of 2006.  The increase in cash provided by operations in 2007 versus 2006 is primarily the result of accounts receivable decreasing at a faster rate than our accounts payable, due to the lower working capital requirements necessary to support ethanol purchases from the marketing alliance partner who left our marketing alliance on April 1, 2007.  Cash on our balance sheet, along with the cash received from the issuance of the $300 million of 10% senior unsecured notes, along with continued strong pricing and demand for ethanol, has significantly helped our working capital position.

Cash available under our liquidity facility.  Our liquidity facility consists of a five-year $200 million senior secured revolving credit facility that may, under certain circumstances, increase in amount up to $300 million.  We had no borrowings outstanding under our secured revolving credit facility at June 30, 2007 and $1.2 million of standby letters of credit outstanding, leaving approximately $70.8 million in additional borrowing availability thereunder as of that date.  As of December 31, 2006, we had no borrowings outstanding under our previous secured revolving credit facility and $4.0 million of standby letters of credit outstanding, leaving approximately $26.0 million in additional borrowing availability under the previous secured revolving credit facility as of that date.  A fixed asset component in an amount of $50 million may be added to the borrowing base under our new senior secured revolving liquidity facility on or prior to December 31, 2007 upon the satisfaction of certain requirements.  We are

27

in the process of satisfying the requirements necessary in order to take advantage of this fixed asset component.

Uses of Liquidity

Our principal uses of liquidity are capital expenditures, payments related to our outstanding debt and liquidity facility, and the repurchase of shares of our common stock.

Capital expenditures.  In the first six months of 2007, capital expenditures (excluding expansion related expenditures) totaled $8.7 million versus $5.1 million in the first six months of 2006.  Capital expenditures include asset replacement, environmental and safety compliance and cost reduction and productivity improvement items.  Our capital spending plan for all of 2007, excluding our expansion projects, is forecasted to be between $20 and $22 million.

Capital expenditures related to our announced expansion projects totaled $69.7 million in the first six months of 2007.  Amounts spent on the Aurora West and Mt. Vernon include the pre-purchasing of long lead-time equipment and stainless steel material, licensing fees and site preparation work in anticipation of receiving environmental permits.  We expect to spend approximately $250 million in total during 2007 on capacity related expenditures.

Payments related to our outstanding debt and liquidity facility.  In the first six months of 2007, we did not make any interest payments on our debt or our liquidity facility.   In the first six months of 2006, we paid $8.7 million in interest payments on our debt and liquidity facility.

Repurchase of shares of common stock.  In the first six months of 2007, we did not repurchase any shares of our common stock under the share repurchase program approved by our Board of Directors.  The share repurchase program allows the repurchase of up to $50 million of our outstanding common stock, although there are no minimum share purchase requirements.  There is approximately $48.8 million available to be repurchased under this program.

Environmental Matters

We are subject to extensive federal, state and local environmental laws, regulations and permit conditions (and interpretations thereof), including those relating to the discharge of materials into the air, water and ground, the generation, storage, handling, use, transportation and disposal of hazardous materials, and the health and safety of our employees.  These laws, regulations, and permits require us to incur significant capital and other costs, including costs to obtain and maintain expensive pollution control equipment.  They may also require us to make operational changes to limit actual or potential impacts to the environment.  A violation of these laws, regulations or permit conditions can result in substantial fines, natural resource damages, criminal sanctions, permit revocations and/or facility shutdowns.  In addition, environmental laws and regulations (and interpretations thereof) change over time, and any such changes, more vigorous enforcement policies or the discovery of currently unknown conditions may require substantial additional environmental expenditures.

We are also subject to potential liability for the investigation and cleanup of environmental contamination at each of the properties that we own or operate and at off-site locations where we arranged for the disposal of hazardous wastes.  From time to time, hazardous material spills have occurred at our facilities or properties, which we investigate and remediate as necessary.  Also, soil and groundwater contamination has been identified in the past at our Pekin, Illinois campus.  If significant contamination is identified at our properties in the future, costs to investigate and remediate this contamination as well as any costs to investigate or remediate associated natural resource damages could

28

be significant.  If any of these sites are subject to investigation and/or remediation requirements, we may be responsible under CERCLA or other environmental laws for all or part of the costs of such investigation and/or remediation, and for damages to natural resources.  We may also be subject to related claims by private parties alleging property damage or personal injury due to exposure to hazardous or other materials at or from such properties.  We have not accrued any amounts for environmental matters as of June 30, 2007.  The ultimate costs of any liabilities that may be identified or the discovery of additional contaminants could adversely impact our results of operation or financial condition.

In addition, the hazards and risks associated with producing and transporting our products (such as fires, natural disasters, explosions, abnormal pressures and spills) may result in spills or releases of hazardous substances, and may result in claims from governmental authorities or third parties relating to actual or alleged personal injury, property damage, or damages to natural resources.  We maintain insurance coverage against some, but not all, potential losses caused by our operations. Our coverage includes, but is not limited to, physical damage to assets, employer’s liability, comprehensive general liability, automobile liability and workers’ compensation.  We do not carry environmental insurance.  We believe that our insurance is adequate for our industry, but losses could occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage.  The occurrence of events which result in significant personal injury or damage to our property, natural resources or third parties that is not covered by insurance could have a material adverse impact on our results of operations and financial condition.

Our air emissions are subject to the federal Clean Air Act, as amended, and similar state laws which generally require us to obtain and maintain air emission permits for our ongoing operations as well as for any expansion of existing facilities or any new facilities.  Obtaining and maintaining those permits requires us to incur costs, and any future more stringent standards may result in increased costs and may limit or interfere with our operating flexibility.  In addition, the permits ultimately issued may impose conditions which are more costly to implement than we had anticipated.  These costs could have a material adverse affect on our financial condition and results of operations.  Because other ethanol manufacturers in the U.S. are and will continue to be subject to similar laws and restrictions, we do not currently believe that our costs to comply with current or future environmental laws and regulations will adversely affect our competitive position with other U.S. ethanol producers.  However, because ethanol is produced and traded internationally, these costs could adversely affect us in our efforts to compete with foreign producers not subject to such stringent requirements.

Federal and state environmental authorities have been investigating alleged excess VOC emissions and other air emissions from many U.S. ethanol plants, including our Illinois and Nebraska facilities.  The matter relating to our Illinois wet mill facility is still pending, and we could be required to install costly additional air pollution control equipment or take other measures to control air pollutant emissions at that facility.  In addition, if the authorities determine our emissions were in violation of applicable law, we would likely be required to pay fines that could be material.

We have made, and expect to continue making, significant capital expenditures on an ongoing basis to comply with increasingly stringent environmental laws, regulations and permits.  We have included in our capital budget for 2007 approximately $10.8 million for projects relating to environmental, health and safety matters, including for the installation of air pollution control equipment and for wastewater discharge improvements at our Illinois wet mill facility.  As of June 30, 2007, we have spent approximately $2.1 million of this amount.  The majority of the 2007 environmental capital budget relates to compliance with the EPA’s final National Emissions Standard for Hazardous Air

29

Pollutants, or NESHAP, under the federal Clean Air Act for industrial, commercial and institutional boilers and process heaters.  This NESHAP requires us to implement maximum achievable control technology at our Illinois wet mill facility to reduce hazardous air pollutant emissions from certain of our boilers and process heaters.  We have been granted an extension until June 12, 2008 to complete work under this NESHAP.  Based on engineering conducted to date and currently available information, we have budgeted $7.4 million to comply with this NESHAP in 2007.  If we do not meet this June 2008 deadline, fines and penalties could be imposed on us, which could be substantial.

We currently generate revenue from the sale of carbon dioxide, which is a co-product of the ethanol production process at each of our Illinois and Nebraska facilities.  New laws or regulations relating to the production, disposal or emissions of carbon dioxide may require us to incur significant additional costs and may also adversely affect our ability to continue generating revenue from carbon dioxide sales.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks, including changes in commodity prices and interest rates.  Market risk is the potential loss arising from adverse changes in market rates and prices.  In the ordinary course of business, we enter into various types of transactions involving financial instruments to manage and reduce the impact of changes in commodity prices and interest rates.  We do not enter into derivatives or other financial instruments for trading or speculative purposes.

Commodity Price Risks

We are subject to market risk with respect to the price and availability of corn, the principal raw material we use to produce ethanol and ethanol by products.  In general, rising corn prices result in lower profit margins and, therefore, represent unfavorable market conditions.  This is especially true when market conditions do not allow us to pass along increased corn costs to our customers.  The availability and price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global demand and supply.  Our weighted average gross corn costs for the three months ended June 30, 2007 and 2006 was $3.99 and $2.27 per bushel, respectively.  For the six month periods ended June 30, 2007 and 2006, our weighted average corn costs were $3.79 and $2.19 per bushel, respectively.

We have firm-price purchase commitments with some of our corn suppliers under which we agree to buy corn at a price set in advance of the actual delivery of that corn to us.  At June 30, 2007, we had commitments to purchase approximately 18.0 million bushels of corn through December 2009 at an average price of $3.98 per bushel from these corn suppliers.  Under these arrangements, we assume the risk of a price decrease in the market price of corn between the time this price is fixed and the time the corn is delivered.  In order to reduce our market exposure to price decreases, at the time we enter into a firm-price purchase commitment, we also often enter into commodity forward contracts to sell a like amount of corn at the then-current price for delivery to the counterparty at a later date.  We account for these transactions under Statement of Financial Accounting Standard No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended by Statement of Financial Accounting Standard No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, and by Statement of Financial Accounting Standard No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging Activities, (hereinafter collectively referred to as “SFAS 133”).  These forward contracts are not designated as hedges and, therefore, are marked to market each period, with corresponding gains and losses recorded in other non-operating income.  The fair value of these derivative assets is recognized in

30

other current assets in the Condensed Consolidated Balance Sheet, net of any cash received from the brokers.  Information on this type of derivative transaction is as follows:

(In millions)	June 30, 2007
Realized and unrealized gains included in earnings	$	3.7

(In millions)	June 30, 2007
Net bushels sold	12.5
Aggregate notional value of derivatives outstanding	$	48.6

Unrealized gain on the fair value of outstanding derivative positions	$	4.7
The change in fair value due to the effect of a 10% adverse change in commodity prices to current fair value	$	(4.4	)

We are also subject to market risk with respect to ethanol pricing.  Our ethanol sales are priced using contracts that can either be fixed; based upon the price of wholesale gasoline plus or minus a fixed amount; or based upon a market price at the time of shipment.  We sometimes fix the price at which we sell ethanol using fixed price physical delivery contracts.  At June 30, 2007, we had fixed contracts to sell approximately 20.7 million gallons of ethanol at an average fixed price of $2.05 per gallon.  These normal purchase/sale transactions are not marked to market.

We also sell forward ethanol using contracts where the price is determined at a point in the future based upon an index plus or minus a fixed amount.  At June 30, 2007, we had sold forward approximately 49.7 million gallons of ethanol using wholesale gasoline as an index plus a fixed spread that averaged $0.03 per gallon.  Under these arrangements, we assume the risk of a price decrease in the market price of gasoline.  In order to reduce our market exposure to price decreases, at the time we enter into a firm sales commitment, we may also enter into commodity forward contracts to sell a like amount of gasoline at the then-current price for delivery to the counterparty at a later date.  We account for these transactions under SFAS 133.  These forward contracts are not designated as hedges and, therefore, are marked to market each period, with corresponding gains and losses recorded in other non-operating income.  The fair value of these derivative assets is recognized in other current assets in the Condensed Consolidated Balance Sheet, net of any cash received from the brokers.  Information on this type of derivative transaction is as follows:

(In millions)	June 30, 2007
Realized and unrealized loss included in earnings	$	(1.5	)

(In millions)	June 30, 2007
Gallons sold	15.2
Aggregate notional value of derivatives outstanding	$	29.8

The change in fair value due to the effect of a 10% adverse change in commodity prices to current fair value	$	(3.1	)

Material Limitations

The disclosures with respect to the above noted risks do not take into account the underlying commitments or anticipated transactions.  If the underlying items were included in the analysis, the gains

31

or losses on the futures contracts may be offset.  Actual results will be determined by a number of factors that are not generally under our control and could vary significantly from those factors disclosed.

We are exposed to credit losses in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to our hedged commitments. Although nonperformance is possible, we do not anticipate nonperformance by any of these parties.

Item 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision of, and with the participation of management, including our Chief Executive Officer, Ronald H. Miller, and our Chief Financial Officer, Ajay Sabherwal, the Company carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report.  Based upon that evaluation, Messrs. Miller and Sabherwal have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures have been designed and are effective to provide reasonable assurance that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission.  These disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed in such reports is accumulated and communicated to our management, including Messrs. Miller and Sabherwal, as appropriate to allow timely decisions regarding the required disclosure.  The design of any system of controls is based in part upon certain assumptions about the likelihood of future events.  There can be no assurance that any design will succeed in achieving its stated goal under all potential future conditions, regardless of how remote.

Changes in Internal Control over Financial Reporting

Based upon evaluation by our management, which was conducted with the participation of Messrs. Miller and Sabherwal, there has been no change in our internal control over financial reporting during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

12

and exclusive remedy for such delay shall be *** per Day (the “Reduced LDs”) commencing on the 31st Day after the Guaranteed Substantial Completion (the “Reduced LD Date”) (unless (x) during the thirty (30) day period between the Guaranteed Substantial Completion Date and the Reduced LD Date a problem arises due to Owner (other than Owner’s exercise of its rights under this Contract) which prevents reaching Substantial Completion by the Reduced LD Date in which event the Reduced LD Date will be extended by the number of days such problem causes Substantial Completion not to be achieved or (y) on the Reduced LD Date Substantial Completion has not been achieved due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T involving a delay in equipment delivery beyond Delta-T’s control (including a delay in delivery of replacement equipment beyond Delta-T’s control which replacement equipment was due to equipment failure) in which event the Reduced LD Date will be extended until such equipment is delivered to the Plant Site); provided further; however, in the event any such delay in Substantial Completion is due both to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T and also to other reasons for which the Base LDs would apply (the “Base LD Causes”), then until such time as the Base LD Causes are remedied such that the only remaining reason, if any, Substantial Completion is not achieved is due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T, then the Base LDs shall be paid by Kiewit to Owner and not the Reduced LDs, and once such Base LD Causes are so remedied, if the defects in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T have not been remedied so that Substantial Completion has not yet been reached, then the Reduced LDs shall be paid by Kiewit to Owner until Substantial Completion is reached.  In addition to the foregoing, and notwithstanding any other provision of this Contract, but subject to Section 16.1, in the event Substantial Completion is not reached by the Guaranteed Substantial Completion Date, Kiewit and Owner agree to work together and with Delta-T in a commercially reasonable and expeditious manner in order to reach Substantial Completion at the earliest possible time.  Kiewit shall use all reasonable efforts to comply with Owner’s wishes with respect to changes in Schedule, but any i) material adjustment requested by Owner to the Schedule; or ii) Owner’s

13

inappropriate disapproval of deliverables as more fully set forth in Section 11.3.2, shall be deemed a change and Kiewit shall have no obligation to slow down or accelerate its performance of the Work except in accordance with Article 6 below.

5.2Threshold.  Upon obtaining Substantial Completion, Kiewit shall have *** days thereafter to increase the output of merchantable ethanol product of the Plant from *** of the Nameplate to *** of the Nameplate (*** per year of undenatured ethanol) (the “Threshold”).  However, so long as Kiewit is working diligently and in good faith to reach the Threshold, Owner shall agree to reasonable extensions of said *** day period.

5.3Early Completion Bonus.  If Substantial Completion of the Plant is attained prior to *** months after the date of the issuance of the Notice to Proceed, Owner shall pay Kiewit at the time of Final Payment an early completion bonus equal to *** of the equivalent of delay liquidated damages rate, had the Work been that same number of Days late for each Day that Substantial Completion occurred prior to said date.  In no event shall the early completion bonus exceed ***.

6.Changes

6.1Issuance of Change Orders by Owner:  Owner may by its written order require changes in the Work within the general scope of the Contract consisting of additions, deletions or other revisions, provided that the Contract Sum and payment schedule are adjusted to reflect the change in Kiewit’s direct and indirect costs resulting from such changes, plus a reasonable amount for profit, and that the time allowed for completion, warranty obligations, and any other obligations of Kiewit affected by the changes are adjusted to cover the consequences to Kiewit resulting from such change.  Kiewit shall have the right to request a claim for such adjustments to the extent the cumulative impact of such changes can reasonably be demonstrated.  The amount to be paid to Kiewit, the effect on the Schedule, if any, and any other adjustments to the Contract will be made by mutual agreement.

then Kiewit shall notify Owner, Owner shall take the necessary corrective actions and the affected Performance Tests shall be re-run at Owner’s expense.  However, if Owner refuses or fails  to provide the requested items, then Kiewit shall have no obligation or liability for any such breach of the applicable warranty or Performance Guarantees under this Contract.

7.5Substantial Completion:  Substantial Completion shall be achieved when the requirements for Substantial Completion in Exhibit E have been satisfied.  Kiewit shall provide Owner a certificate of Substantial Completion certifying that all requirements for Substantial Completion have been met at the time when all requirements for Substantial Completion have been achieved.  Owner shall have three (3) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Substantial Completion has been achieved.  Owner shall specify in detail any requirements for Substantial Completion which it believes Kiewit has failed to achieve within seven (7) Business Days after receipt of such certificate.  Substantial Completion shall be deemed to have occurred on the date when the last of the requirements for Substantial Completion has been achieved.  Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take

19

whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach Substantial Completion; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve Substantial Completion; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

7.6          Cure:  After Substantial Completion (at which point care, custody and control transfers to Owner in accordance with Article 13), Owner shall allow Kiewit reasonable access to the Plant.  After reaching Substantial Completion, Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach the Threshold; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Threshold; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

After reaching the Threshold, Kiewit shall, for a period of up to six (6) months thereafter and subject to Section 16.1, (i) use good faith efforts to  cause the Plant to satisfy the Performance Guarantees in Section 7.3 and to re-run the Performance Tests as needed during that period; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Performance Guarantees; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects, and (ii) complete all Punch List items to the reasonable satisfaction of Owner.  Kiewit shall have the foregoing period of time in which to satisfy the obligations in the preceding sentence before being subject to paying any liquidated damages.

Kiewit is obligated to continue all aspects of the Work necessary to achieve completion of Performance Tests, Substantial Completion, the Threshold, and Final Acceptance (and in connection therewith, Kiewit is obligated to expend all necessary

20

funds, devote all necessary time, and provide or procure all necessary work, materials, labor and services), except as such obligation is limited by Section 16.1 below.  All cost and expense associated with meeting such obligation, including any necessary acceleration of the rate of work will, unless and except to the extent required in accordance with Article 6, be for Kiewit’s account.

7.7Liquidated Damages and Maximum Damages for Performance Guarantees:  If the Plant has achieved Substantial Completion and Threshold, but has not achieved one or more of the Performance Guarantees set forth in Section 7.3 above during a Performance Test as provided herein, and Kiewit has not been able to correct the defect and pass all components of the Performance Tests within the time set forth at Section 7.6 above, then Kiewit shall pay to Owner liquidated damages based on the net amount (i.e. the amount of damages in each case for which damages apply shall be netted against the countervailing factor in each case for which the countervailing factor applies, to determine the final net performance liquidated damages if any) due as set forth in Section 7.8 below up to a maximum cumulative amount in accordance with Article 16 of the General Conditions of this Contract.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, except as such obligation is limited by Section 16.1.  For the avoidance of doubt, the countervailing factors shall not be taken into account for the purposes of determining whether Substantial Completion or the Threshold has been achieved.  Kiewit shall pay such liquidated damages no later than the date that is six (6) months after the achievement of the Threshold.

The sum of the countervailing factors, determined as set forth under Section 7.8 below, shall be deducted from the sum of the damages determined thereunder.  In no case, however, shall Owner have any obligation to pay Kiewit as a result of such calculation.  If the countervailing factors are greater than the damages, the performance liquidated damages shall be deemed to be zero.

21

7.8Amount of Damages and Countervailing Factors

Fuel Ethanol Yield:	*** per *** pounds of anhydrous undenatured ethanol (average per ASTM D4806-06) per pound of dry fermentable starch that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Yield listed in Section 7.3.1 above. To the extent the yield is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall be a countervailing factor. For purposes of calculating damages as set forth above, damages shall be measured in increments of .001. An increment of .0005 or less is rounded down. An increment of .0006 or above would be rounded up.
Fuel Ethanol Production Rate:	*** per 10 US gallons per hour of anhydrous undenatured ethanol (average per ASTM D4806-06) that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Production Rate listed in Section 7.3.1 above. To the extent the rate is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall not be a countervailing factor.
Natural Gas Consumption:	*** *** *** ***

7.9Damages Reasonable:  The Parties acknowledge and agree that the terms of this Contract with respect to liquidated damages, including those payable under this Article 7, are fair and reasonable considering the damage Owner would sustain in the event of the failure of the Plant to meet the Performance Guarantees set forth in Section 7.3 above, that such damages have been agreed upon and fixed as liquidated damages because of the difficulty of ascertaining as of the date hereof the exact damages that would be sustained by Owner, and that such liquidated damages provisions shall be applicable regardless of the actual amount of damages sustained.  All amounts shall be paid as liquidated

22

damages and not as a penalty.  The Parties specifically waive the right to challenge the liquidated damages rates and limits provided herein.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, subject to the limitations set forth in Section 16.1.

7.10Performance Bonus:  Upon Final Acceptance, Kiewit and Owner shall cooperate during a six-month bonus period of operation.  Owner agrees to pay to Kiewit a bonus of *** for each *** above *** of Nameplate, capped at a bonus of ***; provided that the Plant meets the requirements of all applicable permits required for the operation of the Plant on a continuous basis (e.g. if there is an annual limit on emissions, the operation of the Plant at the levels during the applicable period, if operated on a continuous basis for a year, would meet the applicable annual emissions requirements).  Kiewit has six (6) months from Final Acceptance to achieve this bonus.  The bonus shall be determined by reviewing operating data on rolling two-week periods commencing on the date of Final Acceptance.  Bonus shall be payable thirty (30) Days after achieving these bonus criteria.

7.11Training of Owner’s Personnel:  Kiewit shall provide the training described in Exhibit A.  Owner shall provide appropriate personnel, and Kiewit shall provide such training, at times mutually agreed by them, commencing prior to Commissioning in sufficient time to prepare Owner’s employees to perform Commissioning and Startup and to perform their obligations with respect to the Performance Test.

7.12Use of Plant Prior to Final Acceptance:  Owner may use the Plant for commercial purposes on or after the achievement of Substantial Completion.  If Owner elects to use any portion of the Work for commercial purposes prior to Final Acceptance, it shall allow Kiewit reasonably unrestricted access to the Plant to do all things required to be done to complete the Punch List and achieve Final Acceptance and to meet full Performance Guarantees, as long as such access does not unreasonably interfere with Owner’s use of the Plant for commercial

23

purposes.  In the event Owner fails to comply with its obligation to provide Kiewit access to the Plant as set forth in the preceding sentence, (i) for each day that Owner so fails to provide such access, Kiewit shall have an additional day to satisfy its obligations hereunder which were adversely affected by Owner’s failure to so provide such access and (ii) if such failure to so provide such access is for an aggregate of thirty (30) days, then at the end of such thirty (30) aggregate day period, if Final Acceptance has not yet occurred, the matters set forth in items (i), (ii) and (iii) of the definition of Final Acceptance shall be deemed to have occurred.

7.13Final Acceptance:  Kiewit shall provide Owner a certificate of Final Acceptance certifying that all requirements for Final Acceptance have been met at the time when all requirements for Final Acceptance have been achieved.  Owner shall have ten (10) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Final Acceptance has been achieved.  Owner shall specify in detail any requirements for Final Acceptance which it believes Kiewit has failed to achieve.  Final Acceptance shall be deemed to have occurred on the date when the last of the requirements for Final Acceptance has been achieved.

8.Price and Payment

8.1Contract Sum:  Owner will pay Kiewit for the full and satisfactory completion of the Work the Contract Sum of ***, or such other sum as may be adjusted in accordance with this Contract, plus Excluded Taxes required under applicable laws to be paid or remitted by Kiewit in connection with the Work.  Owner shall be credited against the Contract Sum with all amounts paid by Owner or its affiliates under the AWA and the Pre-EPC Agreement.  The Contract Sum includes the cost of materials and Equipment described in the AWA and the Pre-EPC Agreement to the extent such materials and Equipment are incorporated into the Work.  In addition, the Contract Sum includes allowances for each of the matters (and for the amounts) set forth on Exhibit P.  The Contract Sum shall be adjusted for (a) preliminary site Work and piling Work according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such preliminary site Work and piling Work plus a

24

markup of *** and (b) all other Work set forth on Exhibit P (i.e. other than preliminary site Work and pilings Work) according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such Work (without any markup).  All matters covered under the AWA and Pre-EPC Agreement are superseded by the provisions of this Contract and are covered hereby.  The license fee to be paid by Owner under the License Agreement shall be paid by Owner directly to Delta-T and is not included in the Contract Sum.  If the Notice to Proceed is provided more than ninety (90) days after the execution date of this Contract, the Contract Sum and the Guaranteed Substantial Completion Date shall be subject to equitable adjustment in accordance with Article 6.

The Contract Sum does not include Excluded Taxes.  Excluded Taxes means any: (i) taxes imposed by any Governmental Entity on the gross receipts earned by, or paid to, Kiewit on the Contract Sum or any other amounts to be paid by Owner to Kiewit hereunder or any portion of such amounts thereof, (ii) sales or use taxes imposed on Kiewit or any of its Subcontractors for purchases or sales of Equipment or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site or (iii) any property taxes imposed directly or indirectly by any Governmental Entity on the Plant, Equipment, or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site; provided, however, Excluded Taxes do not include any tax based on the net income of Kiewit or its Subcontractors.  If Kiewit or any of its Subcontractors are, now or in the future, required to collect from Owner or pay any Excluded Taxes with respect to all or any part of the Work (other than any such tax based on income), then that amount shall be paid by Owner at Kiewit’s request, in addition to the Contract Sum.  Kiewit shall (and shall make a good faith effort to cause its Subcontractors to) cooperate with and provide reasonable assistance to Owner in obtaining any exclusions, exemptions or credits from any Excluded Taxes and to minimize said Excluded Taxes.  Owner shall hold harmless, defend and indemnify Kiewit and its Subcontractors for, and reimburse to Kiewit or any of its Subcontractors, any Excluded Taxes, interest or penalties associated therewith, or any other amounts, that must be paid by Kiewit or any of its Subcontractors as a result of an assessment or other action by a Governmental Entity as the result of Kiewit’s or Kiewit’s Subcontractors’

25

reliance upon Owner’s claims of entitlement to any exemptions or reductions of Excluded Taxes.  Upon Kiewit or any of its Subcontractors receiving any such assessment or notice of any such other action by a Governmental Entity, Kiewit shall, and shall cause its Subcontractors to, promptly notify Owner of same.  Upon Owner’s receipt of such notice from Kiewit or its Subcontractors, Owner shall undertake the defense of any such assessment or other action by the applicable Governmental Entity, and Kiewit shall, and shall cause its Subcontractors to, cooperate with Owner in such defense.  Owner shall have the right to control such defense of any such assessment or other action by the applicable Governmental Entity.  A preliminary listing of available tax exemptions and concessions expected to be applicable to or available to the construction or operation of the Plant is attached hereto as Exhibit Q.

If Kiewit or any of its Subcontractors are required by applicable laws or are otherwise required to pay Excluded Taxes, Kiewit shall include requests for payment or reimbursement of such Excluded Taxes with Applications for Payment, the Final Payment, or any time within ninety (90) Days of a requirement by a Governmental Entity to pay such Excluded Taxes.

8.2Termination Fee:  In the event that Owner exercises a right to terminate under Section 9.4, or in the event that Kiewit terminates this Contract under Section 9.3 (provided the suspension of the Work which resulted in such termination by Kiewit does not include a suspension due to a Force Majeure Event),  the Owner shall pay in addition to sums due under Section 9.4 of the General Conditions, a fee determined as follows, as a liquidated damage for lost opportunity cost and not as a penalty: 

Termination:	Termination Fee as a Percentage of Total Contract Sum
Within Ninety (90) Days after the Date of Commencement	***
From Ninety-one (91) to one hundred fifty (150) Days after the Date of Commencement	***
From One hundred fifty-one (151) to two hundred ten (210) Days after the Date of Commencement	***

26

8.3Payment Terms:  Owner shall provide a mobilization payment to Kiewit in accordance with and at the times set forth in Exhibit B.  Owner shall make monthly progress payments according to percentage of completion beginning with and including payments made for work done under the AWA or Pre-EPC Agreement as set forth on Exhibit R, which payment schedule shall reflect the concept of “cash neutrality”.  For purposes of this Contract, “cash neutrality” shall mean that Kiewit will not be required to be out of pocket at any time for any amounts owed by Kiewit for the Work and that Kiewit shall not be paid by Owner for the Work in advance in such a manner that would result in Kiewit being cash positive as reasonably estimated by Owner and Kiewit. In the event the payment schedule set forth on Exhibit R conflicts with the foregoing definition of Cash Neutrality, the parties agree to conform said exhibit accordingly.  Kiewit shall submit Applications for Payment in the form set forth at Exhibit B.1, together with reasonable supporting documentation for said Application, to Owner.  Owner shall, through Owner’s Representative, sign the Certificate for Payment set forth on the Application for Payment for the full payment applied for, unless it believes that all or any part of such amount is not then due.  If Owner believes all or part of the amount requested in the Application for Payment is not then due, Owner shall amend the Application for Payment contained therein by indicating the amount, if any, that it believes to be due, and shall sign the application as amended and deliver the certificate, together with written notice of Owner’s reasons for certifying less than the whole amount applied for.  Retainage for each payment shall be *** for a 108 MGY plant; provided however, that Kiewit may provide an adjustable and irrevocable letter of credit in lieu of retainage in a form reasonably acceptable to Owner.  There shall be no retainage for Equipment that was the subject of the AWA.    In addition, upon payment of *** of the Contract Sum (excluding payments for Equipment that was the subject of the AWA), and provided Kiewit is in material compliance with this Contract, there shall be no retainage on any further payments under this Contract.  Upon reaching the Threshold, and provided Contractor is in material compliance with this Contract, Owner shall release the retainage in exchange for Kiewit providing Owner a letter of credit for an amount equal to *** of the agreed upon estimated value of the

27

cost of completion of Punch List items plus any potential liability of Kiewit for liquidated damages.  Owner shall wire transfer, in immediately available funds, all amounts for which it has issued certificates, within fifteen (15) Business Days of the date of its receipt of the Application for Payment, to a bank account to be selected by Kiewit.  If Owner does not certify payment in the amount of the Application, and Kiewit and Owner cannot agree on a revised amount within five (5) Business Days of the date of the Owner’s submittal of the amended Application for less than the full amount, then either Party may commence the Dispute Resolution process in accordance with Article 18.  In any case, when the reasons stated by Owner for withholding payment of any amount for which an application has been made are removed to Owner’s reasonable satisfaction, in whole or in part, Owner shall immediately issue a Certificate for Payment for the amount withheld (to the extent the reason stated for withholding is removed) and make payment, via wire transfer as described in this Section 8.3, of the amount so certified on or before the date that the next payment is due.

8.4Late Payment:  Late payments by either Party shall bear interest at the rate of Wall Street Journal prime rate plus two percent (2%).

8.5Mechanic’s Lien Waivers and Indemnity:  Kiewit shall pay promptly for all amounts due for all materials, labor, Service and Equipment used in or in connection with the performance of this Contract, including those of its Subcontractors, when bills or claims become due, and shall indemnify and hold harmless Owner from and against all claims of its Subcontractors.  Owner shall give Kiewit prompt notice of any such claim upon receipt by Owner of any such claim.

8.6Mechanic’s Liens:  Kiewit shall keep the Plant Site and any other adjacent real property owned or leased by Owner and all other property of Owner which is located on the Plant Site or such adjacent real property, free and clear of laborer’s, materialmen’s and mechanic’s or similar type liens arising out of the performance of the Work, unless Owner fails to make required payments to Kiewit as set forth in this Article 8 and then only to the extent Owner has failed to make such payments.  Owner shall promptly notify Kiewit in writing of any lien so

28

arising of which it has notice or knowledge.  Kiewit shall provide to Owner as a condition to payments to be made pursuant to Article 8, a partial release of lien in the form of Exhibit B.2.1 duly executed by Kiewit and any major Subcontractors (those with subcontracts having a value of over $500,000) and shall also obtain and timely provide a complete release of lien and general release with respect to any such subcontract for which full and final payment is made, in the form of Exhibit B.2.  In each case, the release of lien may be for an amount less amounts that will be paid from the payment for which such release of lien is requested.  Kiewit shall promptly pay each Subcontractor upon receipt of payment from Owner of the amount invoiced that is undisputed and due to such Subcontractor.

If notwithstanding the foregoing, a lien is attached to the Plant, or the Plant Site, or any part thereof, without limiting any other rights of Owner, Owner shall have the right, at its option, to take all action reasonably necessary to discharge such lien upon thirty (30) days prior written notice to Kiewit of such lien.  Kiewit shall reimburse Owner for all amounts expended by Owner to obtain such discharge, including all costs and attorney’s fees and expenses and Owner shall have the right to deduct such amounts from payments otherwise due to Kiewit which will be debts due and payable by Kiewit to Owner.

8.7Final Payment:  Kiewit shall invoice Owner for the final amount due to it under this Contract upon reaching Final Acceptance.  Payment of all of the Contract Sum remaining unpaid, and any and all other amounts owing to Kiewit under the Contract (less and except any amounts owed by Kiewit to Owner), shall be made within thirty (30) Days after Final Acceptance and receipt by Owner of a final invoice; provided, that such payment shall not become due until Kiewit submits to Owner an affidavit in form and substance reasonably satisfactory to Owner that all payrolls, undisputed amounts owed to Subcontractors, suppliers and materialmen and any other indebtedness which might be or give rise to a lien against the Plant or the Plant Site arising out of performance of the Work or any portion thereof have been paid.

29

8.8Effect of Payment

No payment, final or otherwise or verification under this Article 8, shall constitute a waiver of claims by Owner or constitute or be deemed an acceptance, in whole or in part, of any portion of the Plant not in accordance with this Contract.

Upon receipt by Kiewit of payment in respect of the final Application for Payment pursuant to Section 8.7 (“Final Payment”), Kiewit releases Owner from any claim for payment for the Work.  For the avoidance of doubt, the sums paid to Kiewit in respect of its final Application for Payment pursuant to Section 8.7 shall constitute a valid and binding Final Payment for the purposes of this Section 8.8.

8.9Set-Off

Owner may deduct from moneys otherwise due to Kiewit:

(i)any debt or other moneys due from Kiewit to Owner in relation to the Contract; and

(ii)any claim to money which the Owner may have against the Kiewit whether for damages (including liquidated damages) or otherwise, under this Contract or otherwise at law relating to the Work.

9.Rights of Owner and Kiewit to Suspend Work or Terminate

9.1Owner’s Right to Terminate For Cause:  Owner may terminate this Contract if Kiewit commits or is subject to (a) voluntary bankruptcy, liquidation, reorganization or insolvency; (b) involuntary bankruptcy liquidation, reorganization or insolvency; (c) false or materially misleading representation or warranty; (d) assignment or transfer without permission; (e) failure to maintain insurance coverage as required; (f) failure to comply with any applicable law or permit; (g) cessation or abandonment of the Services (unless due to an emergency and then only for the duration necessitated by the emergency or due to Owner’s failure to make payment as required); (h) failure to supply sufficient skilled workers or suitable materials and equipment; (i) failure to achieve Substantial Completion within one hundred eighty (180) Days of the Guaranteed Substantial Completion Date; (j) failure to perform or observe any other material provision of this Contract; or (k) termination or repudiation of the EPC Guaranty

30

or voluntary or involuntary bankruptcy or insolvency of the guarantor under the EPC Guaranty; and, in the case of (c), (e), (f), (g), (h), or (j), Kiewit fails to cure such breach within thirty (30) Days (or such longer period (not to exceed one hundred eighty (180) Days) in the case of (e), (f), (h) or (j)) from written notice of such breach as may be commercially necessary.

Upon such termination Owner may take possession of the Work completed by Kiewit or delivered to the Plant Site and all materials and Equipment at the Plant Site acquired for incorporation into the Work and owned by Owner or Kiewit, take assignment of all purchase orders and subcontracts related to the Work and complete the Work by whatever reasonable method Owner may deem expedient.  Owner shall permit Kiewit access to the Plant Site after such termination as reasonably required by Kiewit to remove any equipment, trailers, supplies, goods and materials maintained by Kiewit in connection with the Work but not intended to be incorporated into the Plant, or owned or used by any of its Subcontractors under subcontracts not to be assigned to Owner.  In the event of termination for any of the reasons set forth above, Kiewit will be liable to Owner for any reasonable costs incurred by Owner to build the Plant as specified, in excess of the Contract Sum, up to a maximum of one hundred percent (100%) of the Contract Sum.  In case of such termination, the license granted under Section 2.4 above shall remain effective.

9.2Kiewit’s Right to Suspend Work:  If Owner does not pay Kiewit amounts that Owner has certified in writing for payment by the date such payment is due, then Kiewit may, upon fifteen (15) Days written notice to Owner, suspend the Work until payment of the amount owing has been received.  If Kiewit suspends the Work under this Section 9.2, then Kiewit shall be entitled to a change order in accordance with Article 6.

9.3Kiewit’s Right to Terminate:  Kiewit may terminate the Contract on fifteen (15) Days written notice to Owner if the Work is suspended, without fault on the part of Kiewit or, any of its Subcontractors, for more than one hundred eighty (180) consecutive Days.  In such event the termination shall be treated as if it were a termination for convenience by Owner, in accordance with Section 9.4, except that no Termination Fee shall be owed under Section 8.2 if such suspension

31

which resulted in such termination included a suspension due to a Force Majeure Event.

9.4Termination for Convenience by Owner.  Owner shall have the right, in its sole discretion, to terminate this Contract for convenience by giving written notice to Kiewit, but in the event of such termination for convenience, Owner will not enter into a contract with another person or entity to construct the Plant.  Upon such notice Kiewit shall immediately stop work and take all necessary and prudent actions to protect and preserve the Work, and to minimize Owner’s costs in terminating the project at that stage of completion.  Upon such termination Owner shall pay Kiewit (a) all amounts then due to it under this Contract as of the date of termination, including all amounts completed but not yet invoiced, and including the portions, if any, of such amounts that would have been held as retainage in accordance with Section 8.3 (or shall release the letter of credit in lieu of retainage, or the Punch-list letter of credit as applicable),  (b) all unavoidable costs payable to Subcontractors, including, without limitation, fees for cancellation or breakage costs, and Kiewit’s costs of demobilization, and (c) a termination fee calculated as set forth in Section 8.2, but in no event shall the total of such amounts set forth in Paragraphs (a) - (c) above exceed the Contract Sum.  For this purpose, the amounts then due to Kiewit shall be deemed to be all amounts billed in accordance with Exhibit B up to the date of termination, plus the value of all goods delivered and services performed under this Contract and not billed as of the date of termination less any amounts which have been prepaid by Owner for said items.  In the event that the Parties cannot agree on the total amount due within thirty (30) Days of the date of Kiewit’s demand for payment hereunder and delivery by Kiewit to Owner of all backup documentation supporting the amounts claimed to be owed by Kiewit, either Party may initiate the Dispute Resolution process set forth in Article 18 below.

9.5Owner’s Right to Suspend.  Owner shall have the right, in its sole discretion to suspend work under this Contract for periods of time up to one hundred eighty (180) days individually and in the aggregate.  In such event, Kiewit shall be entitled to an equitable adjustment to the Contract Sum and to the Schedule in accordance with Article 6 herein, including, but not limited to, an adjustment for

32

costs of escalation for labor and materials, unless such suspension is due to the failure of Kiewit or its Subcontractors to act in accordance with Good Industry Standards in the performance of their obligations under this Contract.

10.Safety and Security

10.1Premises:  Kiewit will keep the Plant Site clean and orderly and will insure that its Subcontractors do likewise.  At completion of the Work, Kiewit shall leave the Plant Site clean of all debris resulting from performance of the Work and in an orderly condition, to enable safe and reliable operation of the Plant in accordance with Applicable Laws.

10.2Security:  During construction and installation of the Work, Kiewit shall be solely responsible to protect the Work and all Equipment and materials to be used in connection with the Work and located on the Work site safe from injury, defacement, theft or damage and all equipment owned or leased by Kiewit or any of its Subcontractors, and all other equipment and goods of any kind located at the Plant Site for the purpose of performing the Work.  Kiewit shall hire guards and watchmen as reasonably necessary to watch the Plant Site and shall take other actions as appropriate to maintain the security of the Plant Site and prevent loss or damage to the Plant, the Equipment or the Plant Site.  Without limiting the foregoing provisions of this Section 10.2, Kiewit shall ensure that lay-down and staging operations, parking and warehousing, is adequately protected from theft, damage or mischief.

10.3Safety: Kiewit will insure all its labor and other authorized personnel comply with all appropriate safety and security regulations, procedures or standards of Kiewit and governmental authorities and in accordance with Owner’s safety standards set forth in Exhibit S attached hereto. Kiewit shall furnish and maintain all necessary safety equipment and training for its employees and shall maintain a safe work site at all times.

33

11.          Project Execution

11.1Kiewit Representatives:  Kiewit will keep a competent Project Manager (“Kiewit’s Project Manager”) assigned to the Work at all times during its performance of the Work and shall immediately notify Owner of said appointment, provided that the appointment shall be subject to the reasonable approval of Owner.  Kiewit’s Project Manager shall represent Kiewit, and written communications given to Kiewit’s Project Manager shall be as binding as if given to Kiewit itself.  Kiewit shall have the Kiewit Project Manager on site, or available in person or by telephone within twenty four 24 hours, at all times during the performance of the Work.

11.2Owner Representative:  Owner will have at all times during the progress of the Work, a competent representative (“Owner’s Representative”) assigned to the Work.  Owner’s Representative shall represent Owner, and written communications given to Owner’s Representative shall be as binding as if given to Owner itself.  Owner shall have its Owner’s Representative on site, or available in person or by telephone within twenty four 24 hours, at all times during the performance of the Work.

11.3Project Reviews and Approvals:

11.3.1     Reviews:  Kiewit will, as appropriate, and additionally upon Owner’s request, issue a project progress schedule to Owner which shall include the schedule and status of construction and procurement activities and estimated time to complete the Work.  Kiewit shall participate in reviews of the progress of the Work at the Work site at Owner’s request as set forth in Exhibit A, and if no provision for progress reviews is made in such exhibit, at Owner’s request up to once each month.  Owner may review and comment on any plan, drawing or specification that Kiewit delivers to Owner.  No review or comment made by Owner shall result in Owner’s being deemed to have assumed any responsibility for any of the Work.  Kiewit shall attempt to incorporate Owner’s comments where it can do so without materially increasing Kiewit’s cost, the time required for performance, or any of its other obligations, but Kiewit shall have no obligation to suspend work to allow time for review and comment except as

34

provided in the Schedule, or to incorporate any of Owner’s comments except as required in order to comply with Kiewit’s obligations under the Contract, or as agreed under Article 6 above.

11.3.2     Approval Process:  If Exhibit A or the Schedule provides for approval by Owner of any document, then, Owner shall be deemed to have given its approval unless it delivers written notice of its disapproval, and the specific reasons for its disapproval within the time allowed according to the Exhibit or Schedule, or in the absence of statement of the time allowed, within five (5) business days of receipt of the document or written request for approval; In the event that the reason for disapproval by the reviewing Party results from failure of the other Party (“submitting Party”) to fulfill any of its obligations under this Contract, then the submitting Party shall correct the work or document requiring correction and resubmit it for review.  The reviewing Party shall have the longer of three (3) Business Days, or one-half the time allowed according to the applicable Exhibit or Schedule if such time is prescribed, for the initial review to approve or disapprove the resubmitted work or document, and it shall be deemed to have given its approval unless it delivers written notice of its disapproval, and the specific reasons for its disapproval, within that time. The review and resubmittal process shall continue in like manner until the submitted Work is approved.  In the event that any disapproval results from a cause other than failure of the submitting Party to fulfill any of its obligations under this Contract, the Guaranteed Substantial Completion Date and other relevant milestones shall automatically be extended as provided at Section 5.1 above.

11.4Notice of Subcontractor Selection:  Kiewit shall, as soon as practicable after award of the Contract, furnish in writing to Owner the names of persons or entities (including those who are proposed to furnish materials or Equipment fabricated to a special design) proposed for major portions of the Work (over $500,000).  If such person or entity is not listed on the pre-approved list of major Subcontractors provided as Exhibit T hereto, Owner may reasonably reject any such proposed person or entity, provided that Owner must reject any such proposed Subcontractor within five (5) Business Days after receipt by Owner of such proposal by Kiewit, or else such proposed Subcontractor shall be deemed acceptable to Owner.  Subject to the preceding sentence, Owner acknowledges

35

(i) that Kiewit, particularly on large or fast-track projects, may not make final selection of some Subcontractors until later in the project, and (ii) that Kiewit has the right to select Subcontractors as long as such selection would not result in failure by Kiewit to satisfy the requirements of this Contract.  The subcontracting of any portion of the Work, as described in Exhibit A, shall not relieve Kiewit of responsibility for performance of the Work as provided therein.  Subject to the foregoing, Kiewit shall have the right to subcontract such portions of the Work (but not all of the Work) as it shall determine to be necessary to others which, in turn, shall have the right to subcontract such portions of the Work assigned to them, if any, as they shall deem necessary.

Kiewit acknowledges and agrees that:

(a)the provisions of this Section 11.4 shall not operate to limit or relieve in any way any obligation of Kiewit to Owner under this Contract, including obligations with respect to the conduct and completion of the Work in strict accordance with the terms of this Contract; and

(b)it will be liable to Owner for all acts, omissions and defaults of the Subcontractors (and those of the employees and agents of the Subcontractors) relating to, or in any way connected with, the Work, to the same extent as if they were the acts, omissions and defaults of Kiewit.

11.5No Privity Between Subcontractors and Owner:  Nothing herein shall establish any contractual relationship or privity between Owner and any Subcontractor.

11.6Relations with Subcontractors

All Work performed by any Subcontractor will be accomplished pursuant to an appropriate agreement which shall provide for a novation or assignment as set forth in Section 12.1.

36

11.7Payments to Subcontractors

Owner shall have no obligation to pay, or to cause the payment of, any moneys to any Subcontractor or any other person acting through, under or on behalf of Kiewit.

12.          Warranty

12.1Warranty:  Kiewit warrants to Owner that the Plant will be free from defects in design, material, and workmanship until twelve (12) months from Substantial Completion.   If any defect covered by the above warranties is discovered within the warranty period, Kiewit shall, subject to the provisions set forth below, repair or replace the defective design, workmanship, material or Equipment, and such repair or replacement (including any ancillary or open “in and out” work required to effectuate such repair or replacement) shall be the sole and exclusive remedy for any warranty claims.  Kiewit shall in no case have any liability, under this warranty or otherwise, for any defect or deterioration which results from failure of Owner to operate the Plant in accordance with applicable manuals and specifications, or from ordinary wear and tear, or should Owner operate the Plant negligently.  Work repaired under warranty shall be re-warrantied for an additional twelve (12) months, provided that all warranties shall expire twenty four (24) months from Substantial Completion, provided any rework under the warranty is not defective.  At the end of the warranty period Kiewit shall, for the protection of Owner, assign to Owner all warranties and guarantees supplied by all major Subcontractors (over $500,000) from who it procured goods or services incorporated into the Work and for any other Subcontractors who have provided extended warranties.

12.2General:  Kiewit warrants that the Work provided by it hereunder will be performed with skill and care and shall be of first quality, new, and in accordance with prudent industry practices.

12.3No Other Warranties:  Kiewit’s sole warranties to Owner under this Contract are the warranties set forth in this Article 12 and in Section 15.2.  OWNER HEREBY ACKNOWLEDGES AND AGREES THAT KIEWIT MAKES NO OTHER WARRANTY UNDER OR BY VIRTUE OF THIS CONTRACT, WHETHER EXPRESS OR IMPLIED (INCLUDING BUT NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY), WHETHER RELATED TO GOODS OR SERVICES,

37

AND THAT KIEWIT MAKES NO WARRANTY OF ANY KIND TO ANYONE OTHER THAN TO OWNER.

44

consequential in nature.  Furthermore, Kiewit’s cumulative liability for any and all losses, claims, or damages of any kind under this Contract, including without limitation liquidated damages payable under Article 5 or Article 7, shall in no event exceed *** of the Contract Sum, which limitation shall be reduced to *** of the Contract Sum upon the achievement of the Threshold; provided, however, that the foregoing limitations of liability to *** of the Contract Sum upon the achievement of the Threshold shall not apply to liability for (i) breach of Kiewit’s obligations to clear liens in accordance with Section 8.6, (ii) fraud or willful misconduct by Kiewit or its Subcontractors (iii) Kiewit’s indemnities pursuant to Article 15, (iv) any right to insurance proceeds Owner may have as a result of its status as “additional insured” on any policy of insurance supplied by Kiewit pursuant to this Contract, or (v) Kiewit’s warranty obligations under Article 12; provided however, that in any event the aggregate limitation of liability of *** of the Contract Sum shall apply.  Notwithstanding any provision herein to the contrary, Kiewit’s liability under this Contract as to costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T (i) which result in the failure to achieve Substantial Completion shall be limited to *** and (ii) after achieving Substantial Completion, which result in the failure to achieve the Threshold shall be limited to the License Fee plus any proceeds from the insurance coverage under Section 14.2(d) resulting from a claim(s) by Owner, and (iii) after achieving the Threshold, which results in the failure to achieve the Performance Guarantees shall be limited to the lesser of the License Fee or the liquidated damages described in Section 7.8 which would apply for failure to achieve the Performance Guarantees, plus any proceeds from the insurance coverage under Section 14.2(d) resulting from a claim(s) by Owner, minus any amounts incurred by Kiewit under item (ii) of this sentence; provided, however, in the event of Delta-T’s bankruptcy or insolvency which results in Delta-T not paying to Kiewit amounts equal to the amount of Kiewit’s liability to Owner under this sentence up to the applicable limitations on liability set forth above in this sentence then in lieu of such applicable limitations on liability, Kiewit’s liability shall be limited to the sum of (x) any amounts paid by Delta-T to Kiewit with respect to such liability of Kiewit to Owner under this sentence, (y) any amounts not yet paid by Kiewit to Delta-T under Kiewit’s subcontract with Delta-T

EXHIBIT C
PERFORMANCE TEST PROTOCOLS

1.Performance Test Protocols

1.1Pre-Test Preparation

1.1.1Prior to the PERFORMANCE TEST, the Plant must have reached Mechanical Completion.  In addition, the OWNER must have run the Plant at or near design rate consistently for a period of ***, as evidenced by Plant operational data provided to KIEWIT by OWNER, before the PERFORMANCE TEST is initiated. This *** operating period may be reduced or waived upon the agreement of the KIEWIT Test Coordinator and the Owner Representative.  Before commencement of PERFORMANCE TEST, KIEWIT shall notify OWNER in writing at least *** prior to planned commencement of the PERFORMANCE TEST that all pre-test conditions have been satisfied, including the following:

·Adequate and competent supervision, personnel and resources for effective operation, maintenance and performance analysis of the Plant, including laboratory analysis, temporary meters or other measuring devices and instrumentation specified as to accuracy and reproducibility by KIEWIT in advance of the PERFORMANCE TEST required to conduct and evaluate the PERFORMANCE TEST shall have been furnished.  The Plant shall be operated and maintained in accordance with the technical advice and instruction from the Operations Manual and on-site directives from KIEWIT, and otherwise within generally accepted practices within the fuel ethanol industry.

·The Plant, its machinery, equipment, instrumentation and piping, shall all be clean lubricated where appropriate, leak tight, and ready to operate according to design specifications.  All systems and appropriate checkouts and calibrations shall have been completed and documented by responsible Plant technicians, contractors, and/or vendors.  Analytical and any special test equipment and reagents will have been calibrated and made accurate.

·Cleaning (CIP) of the process equipment has been accomplished *** or less before the PERFORMANCE TEST per KIEWIT direction and standard procedures set out in the KIEWIT Operations Manual. This requirement to CIP within *** may be reduced or waived upon the agreement of the KIEWIT Test Coordinator and the Owner Representative.  All ingredients and supplies required to complete the test are on hand.  This includes, but is not limited to, feedstock of corn (meeting specifications listed in Article 7 Section 1.2) supplied in stable quantities sufficient to support Plant operation at a rate up to *** of the guaranteed fuel ethanol production rate, as well as sufficient steam, water, stable permanent power, and other utilities, enzymes, chemicals, and other ingredients of the type specified by KIEWIT in the Operations Manual and supplies to support Plant operation at a rate up to *** of the guaranteed fuel ethanol production rate.

·Adequate operation, analytical, and maintenance support shall be scheduled for the test period.

1

1.2Coordination

1.2.1KIEWIT shall coordinate the PERFORMANCE TEST with OWNER during the *** PERFORMANCE TEST period.  This coordination of the PERFORMANCE TEST activities will be handled by a KIEWIT Representative designated to serve as KIEWIT’s Test Coordinator (“Test Coordinator”).  The Test Coordinator will work with an individual designated by the OWNER to be its Representative for the PERFORMANCE TEST to set the test schedule and to coordinate operations during the test period. KIEWIT will also assign KIEWIT Shift Coordinators to support the operation during the test period.

1.2.2OWNER shall supply, or cause to be supplied, all feedstock, utilities and other supplies and services required to conduct the PERFORMANCE TEST, as specified under Section 1.1.1 above, throughout the entire Plant during all PERFORMANCE TESTS.

1.2.3OWNER shall direct its personnel in the operation of the Plant in a manner consistent with the operating parameters provided in the Operations Manual.  Owner’s personnel shall be under the direction of Kiewit.

1.3Conducting the Test

1.3.1The KIEWIT Test Coordinator shall be provided with operating data by the OWNER sufficient to verify that the Plant is operating at a condition suitable for initiation of the PERFORMANCE TEST.  At the scheduled start time of the PERFORMANCE TEST, the KIEWIT Test Coordinator will signal that the test has formally begun and will direct operators to take the initial test measurements. The test will be conducted over a *** period of operation.  During the Test period, the Plant shall be operated by the OWNER in compliance with the KIEWIT Operations Manual and instructions provided by KIEWIT, including, without limitation, adjustments in temperatures, pressures, feedstock rates, steam flow, and other process control inputs, provided these adjustments do not result in unsafe operating conditions.  Plant operators will monitor and record operating data according to standard procedures and in addition will record the supplemental data specified in this protocol on data sheets in the form to be provided by KIEWIT.  Records will be developed from permanent Plant equipment that is calibrated immediately prior to test.  All test measurements will be reviewed by the Test Coordinator (or a designated Representative) and OWNER.  If the Test Coordinator or the Owner Representative believes that there might be a problem with the measurement method or reading, the reading will be retaken and verified by the Test Coordinator and OWNER’S Representative. Immediately upon the conclusion of the PERFORMANCE TEST, the Test Coordinator will meet with Representatives of OWNER to review the test results.  KIEWIT and OWNER shall each be given a copy of the test results.  If the Performance Guarantees have been met, then OWNER shall promptly issue a notice to KIEWIT to such effect.  If the PERFORMANCE TESTS have not been met, then OWNER shall issue a written notice to KIEWIT within *** of completion of the PERFORMANCE TESTS indicating in what manner such Performance Guarantees have not been successfully completed.

1.3.2If the *** test period is interrupted for any reason within KIEWIT’s control or OWNER’S control, a *** test period will resume after the cause for the interruption has been corrected and the Plant has achieved an acceptable operating capacity at substantially the same rate immediately prior to the interruption.  KIEWIT and OWNER shall stop the PERFORMANCE TEST if it becomes obvious that it cannot be carried to a

2

satisfactory conclusion in the current attempt.  If the PERFORMANCE TEST has been interrupted for reasons not attributable to KIEWIT, and continues to be interrupted such that KIEWIT has spent a cumulative period of *** on site since the commencement of the test, then OWNER shall compensate KIEWIT for the personnel that KIEWIT has on site.  This compensation period shall begin on the *** on site, and will continue until the completion of the PERFORMANCE TEST.  This compensation will cease should the inability to complete the PERFORMANCE TEST be the fault of KIEWIT.  Compensation rates shall be at Kiewit’s standard rates.

2.Analytical/Calculation Protocols

2.1Undenatured Fuel Ethanol Quality
	METHOD:	Analyze samples according to ASTM D4806-06. The last test result before emptying day tank into main storage tank shall determine the quality for the batch. The average of all batch test results over the test period shall be used in determining the quality for the PERFORMANCE TEST. If required, a separate sample may be denatured with *** denaturant and the tests repeated to ensure ASTM D4806-06 is met.
		If the fuel ethanol in the day tank does not meet the quality specifications of Article 7, KIEWIT has the discretion to send it on to the main storage tank (on the theory that the blended product in the main storage tank will meet the quality specifications) the average of all batch test results shall be used to establish the blended quality. If the blended fuel ethanol does not meet quality specifications as a result of below quality product measured in one or more day tank batches the volume of the batch(s) shall not be included in ethanol production “rate” quantities used in calculating liquidated damages.
	SAMPLE POINT:	Undenatured Fuel Ethanol Day Tank Storage
	SAMPLE SIZE:	***
	SAMPLE CONTAINER:	Nalgene
	FREQUENCY:	Once per ***
	SAMPLES RETAINED:	All
	PREPARATION:	Standardize test reagents. Clean glassware and sample containers. Assure that reagents are of sufficient quality.
	DOCUMENTATION:	Log results on a PERFORMANCE TEST Data Sheet.
2.2           Undenatured Fuel Ethanol Production Rate

3

	METHOD:	The day tank will be manually measured every *** to serve as the principal method of measurement of production volume, along with a final measurement of the day tank before the contents are sent to the main storage tank(s). In addition, flow totalizer readings will be taken from product meter or other measuring device mutually agreed upon between OWNER and KIEWIT at regular intervals as backup verification of the manual measurements. The total quantity of ethanol produced will be adjusted to a volume equivalent ethanol per ASTM D4806-06. Divide by the total number of test hours to determine the average rate over the test period
	SAMPLE POINT:	Product volumetric totalizing meter (with computer monitoring) after Product Receiver.
	SAMPLE SIZE:	N/A
	SAMPLE CONTAINER:	N/A
	FREQUENCY:	Once per *** and at the end of each Day Tank batch.
	SAMPLES RETAINED:	N/A
	PREPARATION:	Certify that the flow meter is properly calibrated.
	DOCUMENTATION:	Log results on a PERFORMANCE TEST Data Sheet and sign off by the OWNER and KIEWIT.
2.3           Undenatured Fuel Ethanol Yield
	BASIS:	See Section 7.3.1 Anhydrous Fuel Ethanol Yield of the General Conditions.
	METHOD:	Record corn-weigh belt totalizer readings to measure the accumulated meal weight. Measure the sample moisture and starch content. Convert total undenatured ethanol volume from the Rate Test to weight at 60oF. Divide the calculated mass quantity of undenatured ethanol by the calculated corn mass quantity of total starch fed over the time period to determine yield. In addition, this weigh belt total should be cross checked by totaling all corn receipts, subtracting all foreign material content, and taking into account the current corn bin volumes. OWNER and KIEWIT shall mutually agree on the method for the testing of dry fermentable solids.
	TEST POINT:	Corn weigh belt
	FREQUENCY:	Once per ***
	PREPARATION:	Certify that the weigh belt is properly calibrated

4

	DOCUMENTATION:	Log results on “PERFORMANCE TEST Data Sheet”
2.4Natural Gas Consumption
	METHOD:	Record Plant natural gas meter totalizer readings in MCF over test period. Obtain high heat value specification for gas from the utility providing natural gas to the site over the test period and calculate the BTU over the test period. Divide this value by the amount of undenatured ethanol produced during the test period to determine BTU per gallon of undenatured ethanol produced during the test period. Average results of all calculations for test period to determine natural gas consumption value for Performance Test.
	TEST POINT:	Plant gas meter

PROJECT INFORMATION

Site Location and Description

This report presents the results of the geotechnical evaluation performed for the proposed Ethanol Plant site located between County Road ‘N’ and County Road ‘O’ along Highway 34, which is approximately 2 miles west of Aurora, Nebraska. The approximate location of the proposed ethanol plant is shown on the Site Location Plan, included in Appendix A.

At the time of our field exploration, the site was undeveloped with the majority of the site consisting of irrigated farmland. It should be noted that alfalfa was planted at the time of the field exploration. The ground surface was relatively flat and sloped gradually to the south and east. The existing site grades generally slope downward to the east and south with existing ground elevations ranging from a high of about 1813.0 feet in the western area of the site to a low of about 1802.0 feet in the southeast portion of the site.

In addition to the agricultural land, a railroad line running east and west is located along the southern boundary of the project site. An existing farmstead was also noted in the northeast area of the project site.

Project Description

The purpose of the proposed ethanol plant is to provide additional ethanol service to an existing ethanol plant which is located directly to the east of the proposed site. In order to provide access to the ethanol plant, a rail loop and overpass is currently under construction. Loading for the proposed structures at the ethanol plant are based on the structural information provided by Mark Rigdon with Bibb and Associates. A table titled Tank and Vessel Weights for the approximate structural loading conditions and proposed support types for the ethanol plant are presented in Appendix E. The proposed buildings will be slab-on-grade structures with an anticipated finished floor elevation near 1810.0 feet.

The proposed plant will initially be constructed to produce 100 million gallons per year (mgpy) with the capability to be expanded to an ultimate capacity of 220 mgpy. The ethanol plant will consist of grain storage silos and DDG storage silos, various process tanks, fermentation tanks, pre-engineered and engineered buildings, storage tanks, cooling tower, DDGS storage buildings and various equipment pads. The majority of the larger tanks across the site will be supported on an intermediate or deep foundation system with the majority of the buildings being supported on a shallow foundation system. Note that several of the structures are anticipated to be supported on a standard mat foundation system.

2

At the time of this report no information was available regarding the grain storage silos or DDG storage silos. It was assumed based on previous experience that the grain storage silos will require an allowable bearing capacity of at least 8,000 psf. Based on the foundation support requirements, the grain storage silos will likely need to be supported on a deep foundation system.

Based on the anticipated finished floor elevation of 1810.0 feet for the structures and the ground surface elevations obtained at the boring locations by our survey team, maximum excavation depths of approximately 3 feet and maximum fill depth of about 3 feet are anticipated in the plant area. Concrete and/or asphalt paved access and frontage roads will be located across the site along with new rail lines looping around the perimeter of the proposed plant. In regards to the finished floor elevation of 1810.0, the majority of the structures and buildings will be at or near this elevation with exception to the receiving pit, which is typically bearing at a depth of approximately 12 feet below the finished floor elevation of 1810.0.

A new bridge over the rail line is planned at the plant entrance. The proposed overpass will enter from the plant from the west and will be designed as a one-span structure, approximately 95 feet long. The approach abutments and embankments will be constructed using mechanically stabilized earth (MSE) walls. The approach embankments will have a maximum height of 30 feet, at the abutments. A previous geotechnical investigation has already been completed to address the foundation design for the bridge and MSE walls.

A rail line loop is also being installed around the perimeter of the proposed plant area. Earthen embankments will be constructed to maintain the required grade for the rail line. Based on the site plan it is anticipated that the top of rail (TOR) elevation will range from 1807.0 to 1814.0, which will require varying fill and excavation depths along the alignment.

Note: At the time of this report, six storm water detention ponds were planned across the proposed construction site with varying base elevations.

As stated previously, please note that the recommendations for the overpass, MSE walls and rail loop were provided in the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006.

EXPLORATORY AND TEST PROCEDURES

Field Exploration

The field exploration program for the final investigation at the ethanol site consisted of performing 29 soil test borings at the locations depicted on the Boring Location Plan (Appendix A). The borings were staked and the ground surface elevations determined in the field by an OA survey crew. Note that in addition to the soil test borings and laboratory data for the final report, review was made of several supplemental reports that were conducted as part of the varying construction operations for the proposed ethanol plant. Please reference the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006 for the additional information.

The soil test borings were advanced to depths ranging from 20 to 80 feet with a truck-mounted drill rig using 4-inch diameter continuous-flight augers. Soil samples were obtained at selected intervals in the test borings. Soil samples designated as “U” samples on the boring logs (Appendix B) were obtained in general accordance with ASTM D-1587 (Thin-Walled Tube Sampling of Soils). Soil samples designated as “SS” samples were obtained in general accordance with ASTM D-1586 (Penetration Test and Split-Barrel Sampling of Soils). Recovered samples were sealed in steel tubes and transported to a laboratory where they were extruded, sealed in plastic containers, labeled and stored for future laboratory testing.

Descriptions of the soils encountered in the soil test borings were prepared in general accordance with ASTM D-2488 (Visual-Manual Procedure for Description and Identification of Soils). Soil stratification, as shown on the Boring Logs, represents soil conditions at the boring locations; however, variations may occur between or around the boring locations. The lines of demarcation represent the approximate boundary between soil types, but the transition may be more gradual. Water level readings were obtained in the drill holes at the times and under conditions stated on the Boring Logs.

Laboratory Testing

Descriptions of the soils encountered in the soil test borings were prepared in general accordance with ASTM D-2488 (Visual-Manual Procedure for Description and Identification of Soils). Soil stratification, as shown on the Boring Logs, represents soil conditions at the boring locations; however, variations may occur between or around the boring locations. The lines of demarcation represent the approximate boundary between soil types, but the transition may be more gradual.

4

Laboratory tests were performed to evaluate the engineering properties of the recovered soil samples. Unconfined compression tests were used to define the stress-strain characteristics and related shear strength of the cohesive soils. Consolidation tests were performed on thin-walled tube samples of foundation material to evaluate consolidation characteristics under an in-situ and saturated condition. Atterberg Limits tests were conducted to aid in the classification of the soils under the Unified Soils Classification System and to evaluate the shrink/swell characteristics of the soils.

All tests were conducted in general accordance with current American Society of Testing and Materials (ASTM) or other appropriate test procedures. A summary of the laboratory test results is presented in Appendix C.

SUBSURFACE CONDITIONS

Test Boring Summary

The following soil types were encountered in the soil test borings performed at the site.

Developed Zone

Every soil test boring encountered a varying thickness of developed zone (approximately 6 to 12 inches in depth), which consisted of varying amounts of organics and roots. Organic material is typically considered unsuitable for structural support or for use as structural fill due to its high organic content. For budgeting purposes, a 10-inch depth is recommended for topsoil removal.

Peoria Loess

Peoria loess was encountered beneath the developed zone (See Appendix B Boring Logs for locations and depths regarding where the lean clay was encountered). Soils identified as Peoria loess generally were light brown to dark brown, dry to very moist, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 11.2 to 30.1 percent, dry densities ranging from 81.9 to 110.5 pounds per cubic foot (pcf) and unconfined compressive strengths ranging from 0.5 to 1.8 tons per square foot (tsf). Atterberg limit tests performed on the Peoria loess soils indicated liquid limits ranging from 35 to 40 and plastic indexes ranging from 14 to 20. The unconfined compressive strength values indicate a soft to stiff consistency for the cohesive Peoria loess soils.

Sangamon Formation

The Sangamon Formation was encountered beneath the Peoria loess (See Appendix B Boring Logs for locations and depths regarding where the lean clay was encountered). Soils identified as part of the Sangamon Formation generally were dark brown to dark reddish brown, moist to very moist, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 24.7 to 29.9 percent, dry densities ranging from 85.0 to 95.9 pcf and unconfined compressive strengths ranging from 0.8 to 1.0 tsf. The unconfined compressive strength values indicate a firm to stiff consistency for the cohesive Sangamon soils.

6

Loveland Formation

The Loveland formation was encountered beneath the Sangamon Formation at varying depths across the site (See Appendix B Boring Logs for location and depths regarding where the lean clay was encountered). Soils identified as the Loveland formation generally were reddish brown to brown, moist to very, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 15.3 to 27.2 percent, dry densities ranging from 91.2 to 112.9 pcf and unconfined compressive strengths ranging from 0.7 to 3.3 tsf. Atterberg limit tests performed on the Loveland formation indicated liquid limits ranging from 29 to 40 and plastic indexes ranging from 13 to 24. The unconfined compressive strength values indicate a firm to very stiff consistency for the cohesive Loveland formation soils.

Alluvium

The alluvium was encountered at varying depths across the site (See Appendix B Boring Logs for location and depths regarding where the poorly graded to clayey sand was encountered). Soils identified as alluvium generally were light brown, moist to wet, clayey sand to poorly graded sand. The blow counts for the poorly graded alluvium typically ranged from 10 to 67 blows per foot (bpf) indicating a relative density ranging from medium dense to very dense. In addition to the poorly graded sands, lean clay was also noted in soil test borings B-20 and B-23.

After completion of the drilling operations, ground water was not encountered in any of the soil test borings. We note that groundwater levels will fluctuate depending on seasonal variations of precipitation and other factors such as temporary perched conditions near the retention ponds that were not evident or present at the time of drilling. Ultimately, these conditions may result in a groundwater condition that is at a higher elevation at some time in the future. The Drainage and Groundwater Consideration section of this report will address any site drainage concerns.

Note: The previously reported laboratory test data is based solely on the soil test borings that were conducted for this investigation. Review should be made to the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006 for more information on the laboratory test data.

CONCLUSIONS AND RECOMMENDATIONS

The conclusions and recommendations presented in the following sections of this report are based on the information available regarding the proposed construction, the results obtained from our soil test borings and laboratory tests, and our experience with similar projects. Because the samples obtained from the soil test borings represent a very small statistical sampling of subsurface conditions, it is possible that conditions will be encountered during construction that are substantially different from those indicated by the soil test borings. In these instances, adjustments to design and construction may be necessary.

The recommendations presented in this report are based on the Site Plan and project information provided by Aventine Renewable Energy, Inc, Bibb and Associates and the assumptions stated in this report. Changes in the proposed location or design of the structures can have significant effects on the conclusions and recommendations of the geotechnical report. OA should be contacted in the event of such changes to re-evaluate our recommendations.

Site Preparation – Non-Building Areas

Site preparation should begin by removing all vegetation, trees, topsoil, roots, and other deleterious materials. A minimum stripping depth of 10 inches will be required to remove the developed zone material. The stripping depth should be adjusted as necessary in the field to remove all topsoil. The stripped material shall be removed from the proposed construction areas. The topsoil strippings are suitable fill material for covering the last 6 to 9 inches of earthen berms and excavation slopes along with filling in any landscape areas.

In the farm stead area, any required tree removal should also be completed at this time. Care should be taken to thoroughly remove all root systems from the proposed construction areas. Materials disturbed during removal of stumps should be undercut and replaced with structural fill. A zone of desiccated soils may exist in the vicinity of the trees. The desiccated soils have a higher swell potential and should also be undercut and replaced with structural fill. Deeper organic soils may be encountered within more heavily tree-covered areas, which should also be undercut and stockpiled with the topsoil materials.

Site clearing, grubbing, and stripping will need to be performed only during dry weather conditions. Operation of heavy equipment on the site during wet conditions could result in excessive rutting and mixing of organic debris with the underlying soils.

8

Proofrolling operations are recommended in the non-building areas since future expansion is possible. Any areas to receive structural fill in future building or tank areas should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling should also be performed in areas requiring mass excavation after the rough finished subgrade elevation has been achieved. Proofrolling operations should be observed on a full-time basis by a qualified inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The areas that may require undercutting and/or stabilization should be identified at the time of construction, and the stabilization method recommended will depend on the location and depth of the soft area.

Fill placed in the non-building areas should be compacted in accordance with the recommendations stated in the Structural Fill section of the report.

Note: In addition to the tree removal at the existing farm stead in the northwest area of the project site, it will also be critical that all existing building foundations and any grain bin foundation areas be excavated and replaced with structural fill in accordance with the structural fill section of this report. Care should be given to insure that all rubble and concrete associated with demolition operations be removed in its entirety from the project site.

Site Preparation - -Buildings and Tank Areas

In all new fill and excavation areas, vegetation, topsoil, roots, and other deleterious materials (typically 10 inches in depth), deemed unsuitable by the engineer’s field representative shall be removed from the proposed construction areas, and replaced with controlled fill. The topsoil strippings are suitable fill material for covering the last 6 to 9 inches of earthen berms and excavation slopes along with filling in landscape areas. Note that due to the varying crops that have been planted over the years it will be critical that the engineer’s field representative be present to insure all topsoil is properly removed. Areas of extensive root development (especially from alfalfa vegetation) may require additional core-out operations to insure an adequate subgrade is achieved prior to placement of any structural fill.

9

Any required tree removal should also be completed at this time. Care should be taken to thoroughly remove all root systems from the proposed construction areas. Materials disturbed during removal of stumps should be undercut and replaced with structural fill. A zone of desiccated soils may exist in the vicinity of the trees. The desiccated soils have a higher swell potential and should also be undercut and replaced with structural fill. Deeper organic soils may be encountered within more heavily tree-covered areas, which should also be undercut and stockpiled with the topsoil materials.

Site clearing, grubbing, and stripping will need to be performed only during dry weather conditions. Operation of heavy equipment on the site during wet conditions could result in excessive rutting and mixing of organic debris with the underlying soils.

The areas to receive structural fill in the building and tank areas should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling should also be performed in areas requiring mass excavation after rough finished subgrade elevation has been achieved. Proofrolling operations should be observed by a full-time inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The identification of areas that may require undercutting and/or stabilization should be based on the actual conditions at the time of construction, and will depend on the location of the soft area.

NOTE: Information obtained during the field exploration and laboratory testing indicated that there are areas of weak material present across the site. Therefore, it will be critical that proofrolling operations occur across the entire area of the proposed site in order to identify these areas that are near the existing ground surface. Failure to identify and remediate these areas, could result in excessive movement of structures once construction is completed.

Foundation Design

Based on the foundation loading requirements for the proposed structures and stipulated soil bearing capacity conditions, Table 1 is provided to define the acceptable bearing capacity, type of foundation system required and the estimated settlements associated with the various loading conditions. Based on the allowable bearing capacity that is utilized, Table 1 references the recommended foundation system that is at or just below the allowable settlement tolerances.

Note 1) Lack of foundation information does not allow for estimation of settlement. Assumed structure will be supported on an equipment mat.

Note 2) * - No applied load was provided. Reported bearing indicates an allowable bearing capacity.

Note 3) ** - Indicates applied bearing load was calculated from footing dimensions and structure loads

11

Please note that the settlement values listed in Table 1 were calculated based on two conditions. The first condition, listed under the “existing” column, analyzed the soils beneath the foundation elements under the assumption that in-situ soil would remain at the current moisture contents and saturation percentages. The second condition, listed under the “saturated” column, analyzed the soils beneath the foundation elements under the assumption that they became saturated. Overall, the risk of moisture increases and additional consolidation settlement is dependent on the surface drainage conditions and proximity of the structures as they relate to the retention pond locations. These assumptions and well as the degree of conservatism was taken into account when determining the recommended foundation system.

DDGS Storage Building

Based on information from Bibb and Associates and experience with similar structures, it is anticipated that the DDGS Storage Building will be supported on a shallow foundation to carry the building load and a mat foundation/concrete floor slab to carry the live load within the building. Loading conditions, provided by Bibb and Associates indicated a dead load of 2,000 psf for the building structure and an assumed live load of 1,500 psf, would be sufficient for the interior portion of the building where the concrete floor slab is supporting the grain.

Based on the site plan provided by Aventine, it was assumed that the total dimension of the DDGS storage building will be approximately 120 by 600 feet. Loading conditions indicate that the DDGS Storage Building can tolerate 1-inch total and ½-inch differential movement. Due to the deep influence zone induced by the mat foundation/concrete floor slab and the anticipated live load of 1,500 psf, remedial measures are recommended to properly support the proposed structure.

Note: The information contained within the section of the report is based on the assumption that there will be no column loads within the interior portion of the DDGS Storage building. If this assumption is found to be inaccurate, OA should be contacted to reevaluate this section of the report.

Settlement data was utilized to determine the anticipated settlement for the proposed DDGS Storage Building under two conditions. The first condition, analyzed the foundation under a saturated condition, assuming that all of the subgrade would become saturated at some point. The second condition analyzed the foundation under an “in-situ” condition, which assumed that the existing subgrade would remain at its current moisture content and saturation percentage. Based on those assumptions, the anticipated settlement for the first and second conditions resulted in settlement that ranged from 2 to 3 inches and 1 to 2 inches, respectively. Based on previous experience with structures of this size, tolerable ranges of settlement are approximately 2-inch total and 1-inch differential were used as the controlling criteria in our analysis.

12

Based on an assumed finished floor elevation of 1810.0, the placement of approximately 3 to 5 feet of structural fill will be required to reach the floor subgrade elevation. In addition to the structural fill placement within the building footprint and at least 10 feet beyond the perimeter of the DDGS Storage Building a surcharge to an elevation of 1818.0 is required. The intent of the proposed surcharge is to induce consolidation of the underlying soft compressive layers of soil prior to construction operations. The area of surcharge is shown on the Surcharge/Settlement Plate Map (Included in Appendix F).

Based on construction sequence regarding grading operations with respect to foundation installation, it is recommended that mass grading and associated surcharge operations be completed at least 45 to 60 days in advance of foundation/footing construction. The duration of the surcharge or time rate to achieve 90 percent consolidation assumed a double drainage condition. It is recommended that settlement monitoring be implemented to determine when settlement is complete. Two settlement-monitoring plates with locations identified on the Surcharge/Settlement Plate Map (included in Appendix F) are recommended in the areas of the DDGS Storage building. The two settlement plates will verify when primary consolidation is complete while providing the necessary documentation required to determine when foundation excavation operations can begin. The settlement plates should be installed at the present ground surface. During the consolidation process, the elevation of the settlement monuments should be monitored at least twice a week and surveyed to the nearest l00th of a foot. Note that a surcharge load was applied to the Dry Fertilizer Plant as part of the Coop Expansion which resulted in approximately 1.5 inches of settlement in a period of 50 days. Based on the site conditions for the proposed plant, a similar time frame should be expected for the DDGS Storage Building.

All structural fill should be compacted in accordance to the recommendations stated in the Structural Fill section of this report. In regards to the surcharge material placed above the finished floor elevation, it is recommended the material be compacted to at least 90 percent of the proctor value. No moisture range is specified for the surcharge material since it will be removed after the settlement is complete. Because the area of the DDGS Storage building will require structural fill to achieve the finished floor elevation of 1810.0, it is an option after the structural fill is placed to utilize the strippings of the developed zone from across the site as the surcharge material placed above the finish floor elevation. It should be noted, that the developed zone is only suitable for areas of surcharge and care should be used to ensure all of the developed zone strippings are removed from the building area after completion of the surcharge.

13

Upon completion of construction of the DDGS Storage Building, it will be critical that absolutely no moisture may be allowed to enter or weep into the area below the concrete floor slab. To prevent moisture from entering between the areas within the perimeter wall footings it is recommended that caulking be placed in any cold joints and the area beyond the building must have sufficient drainage away from the foundation system.

The site should be graded at a minimum of a 20H:1V slope away from the proposed building, and this should extend a minimum of 40 foot beyond the perimeter of the building. If a slope of 20H:1V is not attainable, concrete pavement should be used to prevent water from entering the subgrade soils around the structure. All cracks and voids in the paving areas must be sealed with caulk to prevent water from infiltrating into the underlying subgrade. As an extra precaution, a high density polyethylene (HDPE) membrane could be attached to the perimeter of the foundation wall to promote drainage away from the foundation systems and minimize the risk of surface runoff from infiltrating into the soil subgrade below the bearing surface of the grain silos, which could ultimately induce additional settlement. If utilized, the HPDE membrane should extend a minimum horizontal distance at least 10 feet out from the ring wall footing.

Note: It is critical these site drainage recommendations be implemented to prevent excessive  settlement.

Shallow Foundations

Based on the results of the subsurface exploration, laboratory test results, and our engineering evaluation, the subsurface conditions at this site are suitable for supporting the proposed structures as identified in Table 1 on a shallow foundation system. The appropriate foundation system should be selected based on tolerable settlement limits for the respective structure. At the proposed finished floor elevations near 1080.0 feet (USGS datum), the exterior and interior shallow foundation system will be supported in the natural clay soils or structural fill, depending on location.

Based on the laboratory test results and the drilling exploration, we recommend that the footings for the structures be designed for the allowable bearing capacities shown in Table 1. The net allowable bearing pressure refers to the bearing pressure at foundation level in excess of the surrounding overburden pressure. The recommended soil bearing capacity includes a factor of safety of at least 3 against shear failure. Footings should have minimum dimensions in accordance with local building codes. Exterior footings and footings in unheated areas should bear at a minimum depth

14

of 3.5 feet below the lowest adjacent final ground surface. It is recommended that any interior footings in heated areas bear at a depth as shallow as possible below the lowest adjacent final ground surface. The analysis for interior and exterior footings utilized a bearing depth of 2 and 3.5 feet, respectively, below the finished floor elevation.

Based on the soil properties estimated for this site, and assuming the recommended bearing capacity from Table 1 for the shallow foundation systems are utilized, any consolidation of the underlying soil is anticipated to be within the tolerable ranges. Provided the recommendations contained in this report are followed, total post-construction settlements are anticipated to be in the ranges as shown in Table 1. To reduce effects of differential settlement and lateral load forces, a floating floor slab, independent from the wall and column loads, with expansion joints will be critical in minimizing the potential cracking that can occur along and around the proposed foundation system. Floor slab control joints should be used to reduce damage due to shrinkage cracks.

It is possible that some soils at the site will have an allowable soil bearing pressure less than the recommended design value. Therefore, foundation bearing surface evaluations should be performed by an OA representative during footing construction to aid in the identification of such soils. After the evaluations and any required remedial measures are performed, concrete should be placed as quickly as possible to avoid exposure of the foundation subsoils to wetting, drying or freezing. If soils in the areas of the foundation support are subjected to such conditions, the footing excavations should be reevaluated.

Intermediate Foundation System

Based on the existing site conditions, required bearing capacities and risk of unacceptable settlement, it is our recommendation that the heavier loaded structures referenced in Table 2 can also be supported on an intermediate foundation system.

In order to achieve total and differential settlement values and to obtain required bearing capacities, we recommend utilizing an intermediate foundation system that can be provided by Geopier© or vibro stone columns. In our opinion, due to the deep influence zones of the large mat and tank foundations; core-out or surcharge load operations would not be feasible due to the extreme depth of excavation or height of surcharge that would be required to reduce the settlements to within acceptable limits. In addition, these types of remedial measures also cause time delays on the order of 60 to 90 days which can often slow down the construction activity on site.

15

The intermediate foundation system would require certain structures be supported on a Geopier© or vibro stone column system. Either foundation system would extend through the compressible zones of material that exist beneath the footprint of the proposed structures and bear into the stiffer material below.

Upon completion of the structural foundation plans, The Geopier Foundation Company, Hayward Baker and Subsurface Constructors, Inc. should be contacted to provide feasibility, design and cost information for the use of either Geopiers© or vibro stone columns, respectively. The following table provides the location, point of contact and respective phone numbers.

TABLE 2
INTERMEDIATE FOUNDATION SYSTEM CONTACTS

Company	Contact	Phone Number	Email Address
Geopier Foundation Company	Bob Lapke	(402) 597-6000	blapke@geopiermw.com
Hayward Baker	Frank Swekosky	(630) 339-4308	FJSwekosky@HaywardBaker.com
Subsurface Constructors	W. Lyle Simonton	(314) 421-2460	lsimonton@subsurfaceconstructors.com

The intermediate systems should include the total cost associated with mobilization, installation of Geopier© or vibro stone columns including concerns related to ground water and soil stabilization of the drilled shaft, and removal of any spoil piles. Based on the most economical cost that meets the previously stated criteria, it is recommended that Aventine Renewable Energy, Inc. enter into an agreement with one of the three companies, so a cost to stabilize the soil can be completed immediately upon completion of the grading operations. Bibb & Associates should be able to provide each firm with the structural drawings that requires the foundation system to be supported on an intermediate system. The intermediate foundation company should also provide recommendations regarding how the shallow footing system is to be supported and/or connected to the intermediate foundation system. OA can provide any input needed to assist in development of those recommendations as well as help coordinate the bidding and award process between the three companies so Aventine Renewable Energy, Inc. receives the most economical bid price.

16

The Geopier© or vibro stone column option will also result in reduced installation time for a given footing location, compared to the time required for installation associated with augered-in-place piles. A vibro stone column or Geopier© system allows for the installation of the concrete footing immediately after the column of crushed aggregate is placed.

Deep Foundation System

Based on the existing site conditions and required foundation bearing capacities, it is our recommendation the grain elevators and grain storage silos be supported on a deep foundation system.

In order to achieve total and differential settlement values and to obtain required bearing capacities, we recommend utilizing an auger cast-in-place foundation system. In our opinion, due to the deep influence zones of the large mat and tank foundations; core-out operations would not be feasible due to the extreme depth of excavation that would be required to reduce the settlements to within acceptable limits.

We recommend the final design utilize auger cast-in-place piles to support the associated mat foundations and tanks. The auger cast-in-place piles should be based on the following:

I.Piles consisting of augered cast-in-place concrete piles utilizing the individual allowable compressive capacities shown in Table 3. A tension capacity equal to three tenths the compressive capacity should be assumed in final design. Minimum center-to-center pile spacing should be no less than 3 pile diameters. No reduction in individual pile capacity for group action is needed for this spacing. The structural capacity of the piles should be determined using applicable AASHTO codes.

II.It is our recommendation the augered, cast-in-place piles bear into the medium dense to dense poorly graded sand. Table 3 indicates the proposed bearing depth of the augered, cast-in-place pile.

17

TABLE 3

DEEP FOUNDATION AUGERED CAST-IN-PLACE PILES

Auger-cast Pile Diameter (inches)	Designed Pile Length (ft)	Minimum Tip Elevation (ft)	Allowable Compressive Capacity (tons)
14	65	1738.0	70
14	70	1733.0	75
16	60	1743.0	77
16	65	1738.0	100
18	60	1743.0	90
18	65	1738.0	120

·Specification requirements that are needed for augered, cast-in-place, concrete piles include design of the grout mix to limit bleeding of completed piles and contractor responsibility for increased length of piles or additional piles to compensate for soil disturbance if it is necessary to withdraw the auger without grouting. The grout mix at a minimum should be required to achieve a 28-day compressive strength of 4,000 psi. The contractor should be assigned responsibility for any effects pile installation has on previously installed piles, and to lengthen the disturbed pile as directed by the geotechnical engineer. It is advisable to prohibit installation of piles less than 6 pile diameters apart, on the same day, to reduce the risk of disturbance to piles containing uncured grout. To check the suitability of the bearing stratum during pile installation, a full-time OA representative should verify that the base depth is no higher than the elevations stated in Table 3 and that each cast-in-place pile is drilled into the medium dense to dense poorly graded sand. The addition of water to aid in drilling should not be allowed. Should the piles be required to resist uplift loads the structural engineer will be required to determine the reinforcement depth through consultation with the geotechnical engineer. In accordance with ACI 318-10.9.1 reinforcing consisting of about 1 percent of the pile cross sectional area to a depth of 10 to 15 feet is common for the augered piles to accommodate incidental bending moments and transient lateral loads. Ultimately the structural engineer should determine the reinforcement required and overall depth based on the design condition parameters.

18

IV.Specifications should require the contractor to provide a grout head pump that will maintain six to eight feet of grout head pressure. It is recommended the specification state that the  auger be extracted at a regular rate of no greater than 2 to 3 feet per second, and the entire cast-in-place pile be placed in a single continuous pour. No construction joints are to be allowed within the pile. It should be noted that the recommended extraction rate is based off of a pump capacity of 1 cubic foot per stroke, and the extraction rate should be adjusted based on the capacity of the grout pump.

V.A previously performed load test was completed for the Coop Expansion and field verified the bearing capacity and associated settlement is within the design parameters, therefore we do feel it is necessary to perform a pile load test of the auger cast pile.

VI.In regards to the connection of the grain bins and silos to the perimeter footing of the ring wall foundations, we recommend utilizing flashing, or some other type of preventative  measure, to ensure that rainwater doesn’t seep or drain into the area between the base of  the tank and concrete mat.

VII.Based on the existing soil conditions encountered in the clays, silts and sands, a lateral modulus of subgrade reaction value of 150 kips per cubic foot is recommended.

VIII.Upon completion of the deep foundation system for each structure and the placement of the structural fill, total post- construction settlements are anticipated to be 1 inch or less with  minimal, if any, differential settlements.

Please note that while this section of the report is specific to the grain silos and DDG silos, the above recommendations are also applicable to the various tanks and structures that were recommended to utilize an intermediate or deep foundation system in Table 1. In the event that it was found to be more cost effective to utilize a deep foundation system rather than a vibro-stone column or Geopier© system, the above recommendations should be utilized for foundation design.

Floor Slab Subgrade Preparation

The soil subgrade in the areas of concrete slab-on-grade support is often disturbed during foundation and superstructure construction. Additionally, floor slab areas are often disturbed by construction equipment traffic between the time of initial grading and final construction. To prepare the floor slab subgrade, the top 12 inches of the subgrade in the building areas below the floor slab

19

should be compacted to a minimum of 98 percent of the maximum dry density as determined by ASTM D698-91, Standard Proctor Moisture-Density Relationship. The moisture content should also be controlled between - -1 and +3 percent of the optimum. The final subgrade should be proofrolled and evaluated by a full-time inspector immediately prior to placement of the concrete to detect any localized areas of instability. If unstable soils are encountered which cannot be adequately densified in place, such soils will typically require the installation of additional crushed stone materials or a geosynthetic over the soft soils.

Regarding the potential for expansive clays, numerous Atterberg limit tests were performed on the soils at the site. Per the graphical plots of the liquid limit and plasticity indexes, expansive soils were encountered at various locations. However, the depth in which they were encountered was well below the anticipated floor elevation and will not influence construction operations. Therefore, no additional remedial measures are deemed necessary to achieve the required criteria of less than 3¤4 inches of potential vertical rise of an exposed concrete floor slab in the building.

Based on the fact that groundwater was not encountered at the time of final drilling operations, the placement of a synthetic barrier to minimize potential vapor rise through the slab is not necessary. Assuming these recommendations are implemented, a subgrade modulus of at least 150 psi/in for the floor slab design is acceptable.

Structural Fill

During construction, we recommend that fill materials placed in the building areas have a liquid limit of less than 50 and a plasticity index less than 30. Whenever possible, highly plastic silt (MH) or fat clay (CH) soils should not be placed within the upper 3 feet of the final ground elevation. Soils in this zone, which have a liquid limit greater than 50 and a plasticity index greater than 30 will typically require removal or blending with less plastic materials to result in lower Atterberg limits.

In addition to the plasticity characteristics, the fill soils should also be relatively free of organic materials (less than about two hundredths of a percent by weight) and other deleterious material. In addition, the soils should not contain particle sizes larger than three inches.

Based on the results of our laboratory testing program, a majority of the on site materials meet the previously mentioned structural fill criteria. During grading operations, representative samples of the proposed structural fill materials should be periodically checked via laboratory testing to verify

20

compliance with structural fill requirements. A representative from the testing agency should be on site on a full-time basis to monitor excavation and grading operation as well as the suitability of fill materials. Any imported fill material should be tested prior to placement at the site to verify it complies with the criteria stated in this section of the report.

Suitable fill material should be placed in thin lifts (lift thickness depends on type of compaction equipment, but in general, lifts of 8 inches loose measurement is recommended). The soil should be compacted by heavy compaction equipment such as a Caterpillar 815 sheepsfoot roller. Within small excavations, such as in utility trenches (less than 24 inches in width), around manholes or behind retaining walls, we recommend the use of “wacker packers”, “Rammax” compactors or vibrating plate compactors to achieve the specified compaction. Loose lift thickness of 4 inches are recommended in small area fills. Structural fill and backfill must be compacted in accordance with the criteria stated in Table 4.

TABLE 4

STRUCTURAL FILL PLACEMENT GUIDELINES

Areas of Fill Placement	Compaction Recommendation (ASTM D698Standard Proctor)	Moisture Content (Percent of Optimum)
If Granular Cushion is utilized Beneath Floor Slab	98%*	As necessary to obtain density
Floor Slab/Soil Subgrade Material – 1’-0” below the base of the floor slab	98%	-1 to +3 percent
Structural fill placed within 10 feet beyond the perimeter of the building pad	98%	-1 to +3 percent
Pavement Aggregate Base – 0’-8” below base of pavement	98%*	As necessary to obtain density
Pavement Soil Subgrade Material – 0’-8” below the base of the Pavement Aggregate Base	98%	-1 to +3 percent
Pavement Soil Subbase - At depths greater than 0’-8” below the base of the Pavement Aggregate Base	95%	-3 to +3 percent
Structural fill placed within the embankment of the railroad lines	98%	-1 to +3 percent
Utility Trenches – Within building and pavement areas	98%	-1 to +3 percent
Storm Detention Pond and Non-structural Fill Areas	95%	-1 to +3 percent
Beneath Landscaped/Grass Areas	92%	As necessary to obtain density

·Alternative Compaction Method – 60% Relative Density

21

The moisture content of suitable borrow soils should generally be between the specified ranges in Table 4. More stringent moisture limits may be necessary with certain soils. Based on the moisture content of the soil samples at the time of drilling operations, adjustments to the moisture content will be necessary to allow compaction in accordance with project specifications. Dependent on the percentage of fines, the clean free-draining aggregates utilized in the granular cushion beneath the floor slab could alternatively be consolidated by means of a vibratory compactor to at least 60% “relative density”, as determined in accordance with ASTM D 4253 (Standard Test Methods for Maximum lndex Density and Unit Weight of Soils Using a Vibratory Table) and D 4254 (Standard Test Methods for Minimum lndex Density and Unit Weight of Soils and Calculations of Relative Density).

Seismic Site Classification

Based on the subsurface conditions encountered in the borings, we recommend using a Seismic Site Class Definition of “D” per IBC 2003. There is no significant risk of liquefaction or mass movement of the on-site soils due to a seismic event.

Pavement Subgrade Preparation

Based on construction activities that have occurred, prior to this report, the upper two to three feet of expansive “hard-pan” Peoria loess has been removed and replaced with imported lean clay for the perimeter loop roadway. In addition the roadways within the plant will have the subgrade properly reworked in the final 8 inches below the aggregate base. Therefore, the final pavement subgrade implemented within the plant just prior to the placement of the concrete pavement should consist of 8 inches of the soil subgrade compacted to at least 98% of ASTM D-698, Standard Proctor, at a moisture content of -1 to +3 percent of optimum. After the subgrade soil is prepared, the area should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling operations should be observed by a full-time inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The identification of areas that may require undercutting and/or stabilization should be based on the actual conditions at the time of construction, and will depend on the location of the soft area.

22

Once the subgrade soil has been visually observed to be stable, we recommend the placement of an 8-inch crushed limestone base course for the Heavy-Duty Pavement. The crushed limestone aggregate should meet the following gradation, which has 80 to 100 percent passing the 1-inch sieve, 50 to 95 percent passing the  ¾-inch sieve, 24 to 55 percent passing the 0.375-inch sieve, 11 to 37 percent passing the No. 4 sieve, 7 to 26 percent passing the No. 10 sieve, and 0 to 6 percent passing the No. 200 sieve. A recycled crushed concrete (NDOR Standard Specifications, Table 1033.11) is also deemed acceptable as an aggregate base. With a design life of 20 years and the seasonal changes in Nebraska, the pavement subgrade meeting the compaction specification at the time of installation has the potential to rapidly deteriorate without the use of an 8-inch crushed limestone base course or recycled crushed concrete. In regards to any future parking lot areas, it is recommended that a 4-inch crushed limestone base or recycled crushed concrete be utilized.

Since the coefficient of drainage is a critical factor in determining the pavement design thickness, it is also recommended that lateral drainage lines be installed along the edge of the roadway pavement for Heavy-Duty Pavement. The drainage lines should properly daylight into drainage ways and/or collector systems. Seasonal weather conditions along with surface runoff saturating the aggregate subbase can have a significant impact on the design life of the pavement. At a minimum, the drainage lines should be located on each side of the roadway edge and flow at least 4 inches below the aggregate subbase. If a storm sewer collection system is anticipated, the edge drains should gravity drain to the randomly located inlets and properly discharge any subsurface water that is collected in the drainage lines. Assuming a drainage system is implemented to eliminate any subsurface water, a good drainage coefficient value of 1.15 was utilized in the pavement design software.

It is important that the subgrade support be relatively uniform, with no abrupt changes in the degree of support. Non-uniform pavement support can result from the transition at cut and fill areas, varying soil moisture contents, varying soil types, and where utility backfill has been placed in areas to be paved. Improper subgrade preparation such as inadequate vegetation removal, proofrolling, and compaction can also result in non-uniform subgrade support.

Pavement Design

Pavement design is influenced by the anticipated traffic loads and volumes for the Aurora West Ethanol Plant, site subgrade conditions, pavement materials, and the desired design life. The recommended pavement thickness is based on our experiences with the alternate pavement types and equivalent pavement sections based on recognized structural coefficients.

23

The recommended design requires that the site be properly prepared in accordance with the Pavement Subgrade Preparation section of this report and that site drainage be provided to minimize the future wetting of the pavement subgrade. A pavement design life of 20 years was used. AASHTO pavement design procedures were used to estimate the required pavement thickness. The following parameters were adopted for the thickness design:

·Equivalent Single Axle Load:	14,000,000 ESAL’s for Access/Frontage Roads
·Equivalent Single Axle Load:	3,000,000 ESAL’s for Intermediate/Haul Roads
·Equivalent Single Axle Load:	200,000 ESAL’s for associated parking lot
·Stabilized Subbase:	8” cohesive lean clay or silt, compacted to at least 98% of ASTM D-698, Standard Proctor, at a moisture content between –1 and +3 percent of optimum
·Stabilized Subbase:	8” crushed limestone/recycled crushed concrete for Intermediate/Haul Roads and Access/Frontage Roads 4” crushed limestone/recycled crushed concrete for parking lot
·CBR value:	3.0
·Working stress (PCC)	600 psi

The Standard-Duty and Heavy-Duty pavement recommendations are based on a design life of 20 years, terminal serviceability = 2.25, reliability = 90%, initial serviceability = 4.2, and standard deviation = 0.35 for rigid pavements. In regards to the load transfer value, the Standard-Duty pavement assumed the saw joints were not doweled but for the Heavy-Duty pavement analysis the analysis utilized doweled joints to achieve the recommended pavement thickness.

Based on the above design parameters, we recommend the following minimum pavement design thickness.

As stated previously, the Heavy-Duty Pavement in addition to the stabilized subbase of 8-inch crushed limestone or recycled crushed concrete should have dowel bars located at the transverse control joints to help eliminate the potential of joint failure. The implementation of dowels at the transverse joints will help transfer the loads and help decrease the necessary thickness of concrete.

25

Surface drainage around the pavement and proper maintenance are also important for long-term performance. Curbs should be backfilled as soon as possible after construction of the pavement. Backfill should be compacted and should be sloped to prevent water from ponding and infiltration under the pavement. All pavement joints should be caulked and any cracks should be quickly patched or sealed to prevent moisture from reaching and softening the subgrade.

[GRAPHIC]

Lateral Earth Pressures

The following soil parameters are provided for use in designing retaining walls, truck dock walls and/or foundation walls subject to lateral earth pressures. The parameters are based on the assumption that retained soils will be similar in composition to the onsite soils that were encountered in this investigation.

Retaining walls which are rigidly restrained at the top and are essentially unable to deflect or rotate should be designed for “at rest” earth pressure conditions. Retaining walls that are unrestrained at the top and are free to deflect or rotate slightly may be designed for “active” earth pressure conditions. The “passive” earth pressure condition should be used to evaluate the resistance of soil to lateral loads. Table 6 presents recommended values of earth pressure coefficients based on our experience with soils in the area. Equivalent fluid densities are frequently used for the calculation of lateral earth pressures for the “at-rest” and “active” conditions and are therefore provided in Table 6. These pressures do not apply to highly expansive clays with Liquid Limits above 50 and Plastic Indexes above 30 or expansive shales. Expansive shales can swell, producing very high lateral earth pressures.

TABLE 6

26

The lateral earth pressure design recommendations are based on the following assumptions:

·For active earth pressure, wall must rotate about base, with top lateral movements 0.002 Z to 0.004 Z, where Z is wall height

·Drained conditions assume a permanent drainage system behind the retaining wall that will allow no development of hydrostatic pressure

·Horizontal backfill (i.e., no sloping backfill above the top of the wall)

·The upper 42 inches do not contribute resistance against horizontal movement if the soil is subject to frost action and seasonal volume change

·Onsite backfill soils having a bulk unit weight of 120 pcf

·Backfill soils placed within the height of the retaining wall consisting of selected lean clay should be tested to verify the lean clays exhibit low plasticity

·Imported granular backfill soils having an angle of internal friction of 32 degrees

·Uniform surcharge, where S is surcharge pressure, in pounds per square foot (psf)

·Heavy equipment and other concentrated load components not included

·No safety factor is included

The cohesive conditions assume the backfill soils placed within seven tenths the height of the retaining wall height consist of selected lean clay or silt exhibiting an Atterberg liquid limit of less than 50. Should the cohesive parameters from Table 6 be utilized, a granular fill of at least two feet behind the wall is still recommended for the drained condition. For granular values to be valid, the granular backfill must extend out from the base of the wall at an angle of 45 and 60 degrees from the active and passive cases, respectively. Utilizing a locally available aggregate meeting the gradation of 100 percent passing the 1-inch, 77 to 97 percent passing the No. 4 sieve, 50 to 70 percent passing the No. 10 sieve, 16 to 40 percent passing the No. 30 sieve and 0 to 3 percent passing the No. 200 sieve is considered acceptable.

To calculate the resistance to sliding, a frictional resistance of 500 psf is recommended for footings bearing on approved cohesive bearing soil. To calculate the resistance to sliding for footings bearing on a suitable crushed limestone, an ultimate coefficient of friction value of 0.5 is recommended. Should the footing bear on the soil subgrade, we recommend using an alternative coefficient of friction of 0.3. Should an aggregate base be utilized as foundation bearing soil, the aggregate should have a minimum friction angle of 32 degrees and assume no cohesion value. A factor of safety of at least 1.5 to 2 should be applied.

27

Slopes and Temporary Excavations

The owner and the contractor should make themselves aware of and become familiar with applicable local, state, and federal safety regulations, including current OSHA excavation and trench safety standards. Construction site safety generally is the sole responsibility of the contractor. The contractor shall also be solely responsible for the means, methods, techniques, sequences, and operations of construction operations. OA is providing the following information solely as a service to our client. Under no circumstances should OA’s provision of the following information be construed to mean that we are assuming responsibility for construction site safety or the contractor’s activities, such responsibility is not implied and should not be inferred.

The contractor should be aware that slope height, slope inclination, and excavation depths (including utility trench excavations) should in no case exceed those specified in local, state, or federal safety regulation; e.g., OSHA Health and Safety Standards for Excavations, 29 CFR Part 19266, or successor regulations. Such regulations are strictly enforced and, if not followed, the owner, the contractor, or earthwork or utility subcontractors could be liable for substantial penalties.

For this site, the overburden soil encountered in the upper 20 feet of our exploratory borings consisted of lean clays. We anticipate that OSHA will classify these materials as type B. OSHA recommends a maximum slope inclination of 1 H: 1V for type B soils.

Note: Soils encountered in the construction excavations may vary significantly across the site. Our soil classifications are based solely on the materials encountered in the widely spaced boring locations. The contractor should verify that similar conditions exist throughout the proposed area of excavation. If different subsurface conditions are encountered at the time of construction, OA must be contacted immediately to evaluate the conditions encountered. If any excavation, including a utility trench, is extended to a depth of more than 20 feet, OSHA requires that the side slopes of such excavation be designed by a professional engineer registered in the state where construction is occurring.

As an alternative to temporary slopes, vertical excavations can be temporarily shored. The contractor or the specialty subcontractor is responsible for the design of the temporary shoring in accordance with applicable regulatory requirements.

28

Construction Equipment Mobility

Some of the soils encountered at this site, may be highly susceptible to softening under the action of construction equipment traffic. Mitigation of equipment mobility problems and management of soft surficial soils will be greatly dependent on the severity of the problem, the season in which construction is performed and prevailing weather conditions.

To reduce equipment mobility problems and in order to deal with soft, wet, surficial soils the following recommendations are provided:

·Optimize surface water drainage at the site to maintain positive drainage away from work areas

·Whenever possible, wait for dry weather conditions to prevail, and do not operate construction equipment on the site during wet conditions. Rutting the surface will only aggravate the problem

·Use construction equipment that is well suited for the intended job under the site conditions. Heavy rubber-tired equipment typically requires better site conditions than light, track-mounted equipment

·Implement a construction schedule that realistically allows for rain days. Pressure to perform earthwork under a tight schedule is frequently counterproductive

Ultimately, it may be necessary to take steps to aggressively improve construction mobility if construction must proceed under unfavorable conditions. Methods for coping with equipment mobility problems may range from removing several feet of soft wet soils, to utilizing crushed stone materials and/or stabilization fabric. Other methods include cement modification of soils, lime stabilization, etc. The optimal approach should be evaluated by the geotechnical engineer at the time of construction.

Corrosivity and Thermal Resistivity of Soils

Note that these sections of the report were recently requested by Bibbs & Associates. Testing is currently underway and will be issued in the form of an addendum once the laboratory analysis is completed.

29

Drainage and Groundwater Considerations

After completion of the drilling operations, ground water was not encountered in any of the soil test borings. Therefore, it is not anticipated to be a concern during construction. We note that groundwater levels will fluctuate depending on seasonal variations of precipitation and other factors that were not evident at the time of drilling and may occur at higher elevations in proximity to the retention ponds at some time in the future.

Since moisture increases to the underlying soil can result in significant settlement, the site should also be graded to avoid water flows, concentrations, or standing water behind retaining walls, building foundations and tanks. If swales are designed at the top of the retaining walls, proper line and slope should be considered to avoid any water flow down behind retaining walls. Special attention to sources of storm water from building and tank roofs, gutter downspouts, and paved areas draining to one point is needed.

Additionally, in order to minimize concerns related to improper drainage away from building foundation that tends to soften when exposed to water, the following general recommendations are provided:

·Site grading should provide for efficient drainage of rainfall away from the tanks, mat foundations, buildings and pavement areas.

·Roof run-off should be collected and transferred directly to the storm sewer system, if possible, or to a location well away from the building and pavements. Conventional downspout drainage leading to splash blocks, though not as desirable, may be used.

·External hose connections should incorporate splash blocks to prevent localized accidental flooding of foundation soils. External hose connections should have cutoff valves inside the building to prevent accidental or unauthorized use of external hose connections.

·Building maintenance personnel should be informed of the potential problems associated with watering in close proximity to the building. Excessive watering of shrubs or lawns near buildings should be avoided. Placement of deep-rooted or water-intensive shrubs near buildings also should be avoided.

DRILLING AND SAMPLING SYMBOLS

SS:	Split-Spoon Sample
U:	Thin-walled Tube Sample
% Rec:	Percentage of Thin-walled Tube sample recovered
SPT Blow Counts:	Standard Penetration Test blows per 6" penetration
HSA:	Hollow Stem Auger
CFA:	Continuous Flight Auger
N.E.:	Not Encountered
N.A.:	Not Available

DRILLING PROCEDURES

Soil sampling and standard penetration testing performed in accordance with ASTM D 1586. The standard penetration resistance (SPT) “N” value is the number of blows of a 140 pound hammer falling 30 inches to drive a 2 inch O.D., 1.4 inch I.D. split-spoon sampler one foot. The thin-walled tube sampling procedure is described by ASTM specification D 1587.

WATER LEVEL MEASUREMENTS

Water levels indicated on the boring logs are levels measured in the borings at the times indicated. In relatively high permeable materials, the indicated levels may reflect the location of groundwater. In low permeability soils, the accurate determination of groundwater levels is not possible with only short-term observations.

SOIL PROPERTIES & DESCRIPTIONS

Soil descriptions are based on the Unified Soil Classification System (USCS) as outlined in ASTM Designations D-2487 and D-2488. The USCS group symbol shown on the boring logs correspond to the group names listed below.

Group Symbol	Group Name
GW	Well Graded Gravel
GP	Poorly Graded Gravel
GM	Silty Gravel

RE:	Aventine - Aurora West Ethanol Plant Addendum #1 – Chemical and Thermal Resistivity Testing
DATE:	May 15, 2007
PROJECT #:	2006-1563

The following sections of this addendum should be added to the Report of Geotechnical Exploration performed for the Aurora West Ethanol Plant dated April 20, 2007.

Corrosivity of Soils

A series of chemical tests were performed in accordance with AWWA C105/A21.5-05, Appendix A on representative samples of the subsurface soils. The results are presented in Table 1 below and are attached to this addendum.

TABLE 1
CHEMICAL TESTING RESULTS

Sample Boring	Sample  Depth (ft)	Resistivity (ohm/cm)	PH	Redox (mV)	Sulfides (mg/kg)
B-2	8.5-10.0	1261	6.7	282	NEG
B-3	3.5-5.0	4017	8.0	248	NEG
B-6	3.5-5.0	2018	7.4	247	NEG
B-12	1.0-2.5	4582	7.6	235	NEG
B-19	1.0-2.5	5897	7.7	237	NEG
B-22	3.5-5.0	6064	7.5	235	NEG
B-24	1.0-2.5	5275	5.8	268	NEG

Once compiled, the results of the chemical testing were evaluated on a point system utilizing the criteria presented in Table 2 to determine potentially corrosive conditions for underground utilities.

* Ten points indicates that soil is corrosive to ductile-iron pipe; protection is needed.

† If sulfides are present and low or negative redox-potential results are obtained, add three points for this range.

Based on the test results of the chemical tests and point system presented in Table 2, the following point totals for each sample is provided in Table 3.

TABLE 3
CORROSIVITY POINT SYSTEM

Sample	Sample	Points
Boring	Depth (ft)	Resistivity	PH	Redox	Sulfides	Moisture	Total
B-2	8.5-10.0	10	0	0	0	2	12
B-3	3.5-5.0	0	0	0	0	2	2
B-6	3.5-5.0	5	0	0	0	2	7
B-12	1.0-2.5	0	0	0	0	2	2
B-19	1.0-2.5	0	0	0	0	2	2
B-22	3.5-5.0	0	0	0	0	2	2
B-24	1.0-2.5	0	0	0	0	2	2

The results of the tests indicate the point total varies from 2 to 12 across the site. Based on the AWWA guidelines, any point total greater than 10 requires corrosion protection. Therefore, it is recommended that any ductile iron pipe in the vicinity of soil test boring B-2 be double polyethylene encased. In addition, please note that the higher resistivity condition encountered in soil test boring B-2 was at a depth of 8.5 to 10 feet. Based on the overall results and proposed grading operations, it is also recommended that any utility lines located at depths greater than 5 feet below the existing borehole elevation be double encased.

A series of chemical tests according to AASHTO T-290 and AASHTO T-291 regarding sulfate and chloride content were also performed on representative samples of the subsurface soils. These tests were used to evaluate the soils for specific chemical factors that could be aggressive to concrete. The factors, in addition to the above pH and Redox values, include sulfate and chloride content. The results are defined as parts per million (ppm) and are provided in Table 4.

TABLE 4
CHEMICAL TESTS ON SOIL SAMPLES

Boring	Depth	Sulfates (ppm)		Chlorides (ppm)
No.	(ft)	Test Results	Required	Test Results	Required
B-2	8.5-10.0	12.1	Max. 200	4.1	Max. 100
B-3	3.5-5.0	15.5	Max. 200	4.2	Max. 100
B-6	3.5-5.0	21.1	Max. 200	5.5	Max. 100
B-12	1.0-2.5	20.1	Max. 200	4.0	Max. 100
B-19	1.0-2.5	15.4	Max. 200	3.9	Max. 100
B-22	3.5-5.0	19.1	Max. 200	4.7	Max. 100
B-24	1.0-2.5	17.7	Max. 200	5.2	Max. 100

Based on our experience and soil survey information, sulfate and chloride resistant cement will not be required for any

exposed concrete. Regarding the cement type based on the chemical test readings of sulfates and chlorides less than 200 ppm and 100 ppm, respectively, a Type I or Type II cement is considered acceptable. Maximum water/cement ratio by weight shall not exceed 0.5. Actual test results are included in the Appendix C, Laboratory Test Data.

Thermal Resistivity of Soils

A series of Thermal Resistivity testing was completed in accordance with ASTM D-5334 and IEEE 442. The results from the testing are presented in Table 5 below and are attached to this addendum.

TABLE 5
THERMAL RESISTIVITY TESTS ON SOIL SAMPLES

B-22	Remolded	102.2	14.8	78		234

* - Represents erroneous data due to sample contamination

Samples that were submitted for testing were tested under two conditions. The first condition required that the sample be remolded to resemble the in-situ soil conditions in each respective soil test boring. Upon obtaining the desired dry density and moisture content, the Thermal Resistivity was measured. The sample was then dried in an oven and tested again to determine the Thermal Resistivity of the material with no moisture.

It is important to note that the results from soil test boring B-20 are invalid and should be excluded from the data set. Laboratory notes indicate that the sample was primarily sand which is not representative of the upper 10 feet of the on-site material.

EXHIBIT E
MECHANICAL COMPLETION, COMMISSIONING, STARTUP

Definitions:

Mechanical Completion:  The completion of construction activities essential to the safe and proper operation of the Plant in accordance with the requirements of the Contract, as more fully listed below to the extent necessary to permit:

(i)safe and sound start-up and operation of the Plant as a fully integrated system; and

(ii)successful completion and conduct of the commissioning tests.

but excluding correction of minor non-operational matters such as painting, landscaping and nonessential insulation.  Nonessential insulation shall not include any insulation needed for personnel safety, any insulation that materially and negatively impacts the process or any outdoor process piping insulation required for freeze protection.

Irrespective of the following, Mechanical Completion shall be deemed to have occurred in the event feedstock has been introduced into the process and ethanol has been produced.

Commissioning:  The checking, testing and preparation of the Plant for operation, functional control loop checking, interlock testing, system purging and utility system startups, as more fully listed below.  In general, the tasks required for taking the Plant from Mechanical Completion and making it ready for start-up.

Ready for Startup:  When the activities listed for Mechanical Completion and Commissioning have occurred and the Plant is ready to mill corn at the hammer mills.  At that time, KIEWIT will notify OWNER that the Plant is Ready for Startup.  All paved roads must be completed before the Plant is ready for Startup.

Startup:  Startup begins with the initial feed of raw material to the Plant, filling of Equipment with operating material, startup and operation of individual process stages, adjustment and optimization of operating conditions, optimization of control loops, verification of startup, shutdown and partial load operations.  Utility system startups (unless integrated with the processing portions of the Plant) are a part of the Commissioning Phase.

Substantial Completion:  As defined below.

These events may not occur at the same point in time for all parts of the Plant.  Utility systems needed for operation of the rest of the Plant may reach Mechanical Completion, Commissioning and Startup before the main process parts of the Plant.  Some processing areas of the Plant or sub-systems of operating areas may reach Mechanical Completion and be Commissioned and Started up before other parts of the Plant, for example, grain receiving and storage may be completed and into operation, i.e., filled with grain, prior to other parts of the Plant.  Mechanical Completion, Commissioning and

1

Startup shall not be deemed to occur, however, until all portions of the Plant meet the requirements for each such stage.

The following lists indicate the activities or events, which take place in each of the phases described.

Mechanical Completion

·Inspection of all equipment to check that erected facilities conform to construction drawings and Contract specifications.

·Non-operating field leak tests or field pressure tests on piping and field-fabricated equipment as required by the Contract specifications, disposing of test media on site at a location specified by OWNER, and removal of test blinds and restoring systems to “ready for operation” condition.

PROCESS SAFETY MANAGEMENT
CONTRACTORS

A.Policy

Aventine Renewable Energy, Inc. is committed to the prevention of accidents and improving quality and productivity related to Contractor work by providing a safe workplace that protects Aventine and Contractor employees, the environment and the general public.

Aventine shall promote an attitude of partnership, cooperation, and communication with Contractors to enhance workplace safety. Personal safety is a fundamental responsibility of both Aventine and Contractor employees.

Aventine shall maintain the independent contractor status of its Contractors and their Subcontractors. Aventine shall not dictate the manner and means by which the Contractor performs its work, except where specified in the written contract; and, whenever unsafe acts/unsafe conditions pose an immediate threat to the safety or health of personnel; and/or potential damage to Aventine property.

B.Purpose

To establish a policy and procedure for providing Aventine employees with guidance in developing site-specific rules and practices to improve the safety and health performance of contractors who perform work at Aventine.

To ensure that all Contractor personnel are informed of the known potential fire, explosion, toxic release hazards, and other serious safety hazards related to their work or the process.

To ensure that all Contractor personnel are aware of all applicable Aventine safety rules and procedures pertaining to their work site, including the facility’s emergency procedures.

This procedure applies to Aventine employees responsible for Contractor selection, training, inspections and assessments, and for Contractor work involving new construction projects, major renovation, and repair/maintenance activities.

* Note: Repair/maintenance activities and incidental contractor work that do not compromise the safety of personnel, facilities, and processes are excluded. (E.g., janitorial and delivery services, etc.)

1

C.        Approach

Contract employees must perform their work safely. Considering that Contractors often perform very specialized and potentially hazardous tasks, such as confined space entry activities and non-routine repair activities; their work must be controlled while they are on or near a process covered by PSM. A permit system or work authorization system for these types of activities are required for all affected employees. The use of a work authorization system keeps an employer informed of contract employee activities. A well-run and well-maintained process, where employee safety is fully recognized benefits all of those who work in the facility whether they are employees of the employer or the contractor.

D.Responsibilities

When selecting a contractor, the employer must obtain and evaluate information regarding the contract employer’s safety performance and programs. The employer also must inform contract employers of the known potential fire, explosion, or toxic release hazards related to the contractor’s work and the process. The employers must explain to contract employers the applicable provisions of the emergency action plan; develop and implement safe work practices to control the presence, entrance, and exit of contract employers and contract employees in covered process areas; evaluate periodically the performance of contract employers in fulfilling their obligations; and maintain a contract employee injury and illness log related to the contractor’s work in the process areas.

E.Program Elements

·The Contractor and any personnel under his jurisdiction shall continuously observe and enforce all applicable governmental safety regulations and all safety rules and signs that may have been or may be established by Aventine. Proper safety procedures and equipment must be utilized and maintained at al times for protection of all personnel and facilities.

·Before beginning work, the Contractor or his qualified supervisors shall inspect the premises, location of work area, and examine all safety rules and instructions to determine the nature and extent of difficulties and hazards.

·Contractor shall promptly report in writing, all accidents in connection with the work. Full details and statements of witnesses shall be included in the reports on any accident that has resulted in injury, property damage, or death.

·Aventine reserves the right to suspend any Contractor where life or Company property is imperiled. The Contractor shall suspend work when notified by the Company that any personnel or equipment are exposed to unreasonable hazards.

2

·Aventine shall issue Cutting and Welding permits before any cutting or welding is performed in the plant. These permits shall be renewed each day. Outside Contractors shall provide adequate fire protection equipment at the job site, and Cutting and Welding equipment shall be maintained and used as per O.S.H.A. standards. An Alcohol Area Hot Work Permit must be obtained for any work in the alcohol production storage or loading areas, or any other areas defined by the Plant contact.

·Contractors shall obtain approval from the Plant contact prior to moving any heavy construction equipment from one area to another. Flagmen or groundmen will be provided by the Contractor as needed ahead of or behind any heavy moving loads to ensure safe movement of this equipment.

·Contractors’ equipment, supplies and building materials shall be kept in order at all times to eliminate accident hazard and possible injury to employees and its security is the responsibility of the Contractor.

·At the end of the workday, work areas shall be fenced, boarded and lighted as necessary. All of the Contractors’ equipment shall be shut off and all obstacles removed from all walking areas.

·All drivers of Contractors’ vehicles are required to observe speed limits and posted instructions on Company roads.

·Movement of Contractor’s personnel on Company property MUST be confined to the location of their work site. In going to and from designated work assignments, Contractors’ personnel must stay on established roads and walks. They must not walk through buildings or shops.

a.)All Contractors’ will sign in and out or use the provided swipe cards to enter and leave the plant on a daily basis at the Security Office.

b.) All Contractors’ and equipment will enter and leave the plant via the Main Gate as directed by Security.

c.)Contractor trucks are NOT TO BE USED TO CARRY EMPLOYEES TO AND FROM THE WORK AREA IN AN UNSAFE MANNER. (E.g. workers are not to ride in the back of pickup trucks, on forklifts, etc.) Any worker riding in a Contractors’ vehicle must be in a belted seat.

5.             Schedule

5.1Schedule:  Kiewit guarantees that Substantial Completion of the Work will be achieved no later than, the later of (i) *** or (ii) ***, (“Guaranteed Substantial Completion Date”). Owner will not provide Kiewit the Notice to Proceed until the Air Permit is issued and any permits or approval necessary to provide reasonably unrestricted access to the Plant Site in order for Kiewit to be able to perform the Work are issued and/or obtained.   In the event of a delay in Substantial Completion not permitted by the terms of this Contract, except as otherwise set forth in this Section 5.1, Kiewit’s sole and exclusive liability and Owner’s sole and exclusive remedy for such delay shall be:  (i) Days 1 — 30, $ ***, (ii) Days 31 — 60,

12

***, and (iii) Days 61 plus, $ *** (the “Base LDs”); provided, however, in the event any such delay in Substantial Completion is due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T, then, except as otherwise set forth in this Section 5.1, Kiewit’s sole and exclusive liability and Owner’s sole and exclusive remedy for such delay shall be $ *** per Day (the “Reduced LDs”) commencing on the 31st Day after the Guaranteed Substantial Completion (the “Reduced LD Date”) (unless (x) during the thirty (30) day period between the Guaranteed Substantial Completion Date and the Reduced LD Date a problem arises due to Owner (other than Owner’s exercise of its rights under this Contract) which prevents reaching Substantial Completion by the Reduced LD Date in which event the Reduced LD Date will be extended by the number of days such problem causes Substantial Completion not to be achieved or (y) on the Reduced LD Date Substantial Completion has not been achieved due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T involving a delay in equipment delivery beyond Delta-T’s control (including a delay in delivery of replacement equipment beyond Delta-T’s control which replacement equipment was due to equipment failure) in which event the Reduced LD Date will be extended until such equipment is delivered to the Plant Site); provided further; however, in the event any such delay in Substantial Completion is due both to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T and also to other reasons for which the Base LDs would apply (the “Base LD Causes”), then until such time as the Base LD Causes are remedied such that the only remaining reason, if any, Substantial Completion is not achieved is due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T, then the Base LDs shall be paid by Kiewit to Owner and not the Reduced LDs, and once such Base LD Causes are so remedied, if the defects in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T have not been remedied so that Substantial Completion has not yet been reached, then the Reduced LDs shall be paid by Kiewit to Owner until Substantial Completion is reached.  In addition to the foregoing, and notwithstanding any other provision of this Contract, but subject to Section 16.1, in the event Substantial Completion is not reached by the Guaranteed Substantial Completion Date, Kiewit and Owner agree to work together and with Delta-T in a

13

commercially reasonable and expeditious manner in order to reach Substantial Completion at the earliest possible time.  Kiewit shall use all reasonable efforts to comply with Owner’s wishes with respect to changes in Schedule, but any i) material adjustment requested by Owner to the Schedule; or ii) Owner’s inappropriate disapproval of deliverables as more fully set forth in Section 11.3.2, shall be deemed a change and Kiewit shall have no obligation to slow down or accelerate its performance of the Work except in accordance with Article 6 below.

5.2Threshold.  Upon obtaining Substantial Completion, Kiewit shall have *** days thereafter to increase the output of merchantable ethanol product of the Plant from *** of the Nameplate to *** of the Nameplate (*** per year of undenatured ethanol) (the “Threshold”).  However, so long as Kiewit is working diligently and in good faith to reach the Threshold, Owner shall agree to reasonable extensions of said *** day period.

5.3Early Completion Bonus.  If Substantial Completion of the Plant is attained prior to *** months after the date of the issuance of the Notice to Proceed, Owner shall pay Kiewit at the time of Final Payment an early completion bonus equal to *** of the equivalent of delay liquidated damages rate, had the Work been that same number of Days late for each Day that Substantial Completion occurred prior to said date.  In no event shall the early completion bonus exceed ***.

6.             Changes

6.1Issuance of Change Orders by Owner:  Owner may by its written order require changes in the Work within the general scope of the Contract consisting of additions, deletions or other revisions, provided that the Contract Sum and payment schedule are adjusted to reflect the change in Kiewit’s direct and indirect costs resulting from such changes, plus a reasonable amount for profit, and that the time allowed for completion, warranty obligations, and any other obligations of Kiewit affected by the changes are adjusted to cover the consequences to Kiewit resulting from such change.  Kiewit shall have the right to request a claim for such adjustments to the extent the cumulative impact of such changes can reasonably be demonstrated.  The amount to be paid to

Kiewit, the effect on the Schedule, if any, and any other adjustments to the Contract will be made by mutual agreement.

6.1.1       Change Order Effect upon Performance.  If the change submitted by Owner, in Kiewit’s good faith reasonable judgment, would have a detrimental impact on performance of the Plant, Kiewit will have no obligation to proceed with any change.

6.1.2       Change Order Dispute.  If there is a dispute as to whether a change order is required, then Kiewit shall proceed with the change, without markup, on a reimbursable basis until the dispute is resolved in accordance with Article 18.  If it is determined that a change order was required then Owner shall pay Kiewit on a cost plus basis in accordance with Section 6.1.4 below.  If it is determined that no change order is required then Kiewit shall reimburse Owner for the amount that Owner has paid to Kiewit for said Work, together with interest at the rate set forth in Section 8.4 below.

If the amount of the change order is in dispute, then Kiewit will proceed with the change on a cost plus basis in accordance with Section 6.1.4 below.

6.1.3       Hazardous Substances.  Kiewit shall in no case be required to agree to any change requiring Kiewit’s handling of PCBs, asbestos or any other Hazardous Substances except to the extent such Hazardous Substance is brought onto the site by Kiewit and/or Subcontractors (and not subsequently negligently released by Owner or its other contractors or agents) or results from negligent exacerbation of a known environmental condition by Kiewit or its Subcontractors.

6.1.4       Changes Priced On Cost Plus Basis.  For changes priced on a cost plus basis, Kiewit shall be entitled to a *** total markup for off-site overhead, contingency and profit.

6.1.5       Change Order for Expansion.  Owner’s issuance of a change order for the expansion of Nameplate from 108,000,000 to 216,000,000 gallons per year of un-denatured ethanol shall be allowed as within the general scope of the

15

Contract and Kiewit shall be entitled to a change in the Contract Sum, Schedule, and Services, as mutually agreed so long as Owner first executes an amended technology license agreement with Delta-T.

6.2Notice of Instruction Constituting a Change; Notice of Impact of Change Order:  If Kiewit receives instructions from Owner, which in Kiewit’s opinion constitute a change in the Work, Kiewit shall so advise Owner within eight (8) Business Days of receipt of such instruction.  If Kiewit receives a change order under Section 6.1 above or becomes aware of a constructive change order described at Section 6.3 below, or gives Owner a notice that an instruction of Owner constitutes a change, then Kiewit shall within eight (8) Business Days thereafter submit to Owner a statement of the impact of such change on the Contract Sum, payment schedule or Schedule; provided however, the warranties and any other provisions of the Contract will not be affected thereby.  Kiewit shall not delay prosecution of the Work.

6.3Constructive Change Orders:  Any of the following shall entitle Kiewit to request an increase in the Contract Sum and/or an extension of the Schedule: (a) a material modification of applicable law, ordinance or regulation after the Date of Commencement, (b) a Force Majeure Event (provided however that in no event shall Kiewit be entitled to an increase in the Contract Sum to the extent due to a Force Majeure Event), (c) unknown or differing site conditions at the Plant Site described at Article 4 above, (d) discovery of Hazardous Substances or archaeological materials at the Plant Site which were not previously disclosed to or known by Kiewit, (e) suspension by Owner, (f) material delay by Owner, or its subcontractors in the performance of Owner’s obligations under the Contract, that results in a material delay in the performance of the Work by Contractor or its Subcontractors, (g) interference (but not the exercise of Owner’s rights under the Contract) by Owner or its subcontractors in any material respect in the performance by Contractor, or its Subcontractors, of the Work that results in a material delay in the performance of the Work by Contractor or its subcontractors, and (h) suspension or injunction by court order (unless such suspension or injunction is the result of actions taken by Kiewit or its Subcontractors under this Contract).  Kiewit shall provide written notice to Owner

16

promptly upon becoming aware of any of the events above, or, in the case of a Force Majeure Event, promptly upon becoming aware that there may be a schedule impact  from such event.

7.             Commissioning, Testing, and Performance

7.1Mechanical Completion, Commissioning and Startup:  Commencing six (6) months prior to the anticipated Mechanical Completion Date, Kiewit shall provide to Owner written notice of said estimated date and provide, not less than monthly, periodic written updates of this estimated completion date.  Kiewit shall give Owner prompt reasonable written notice when Kiewit believes that the Work has reached Mechanical Completion.  Kiewit shall commence Commissioning upon achievement of Mechanical Completion.  Mechanical Completion shall be achieved when the requirements therefor listed in Exhibit E have been satisfied.  Kiewit shall Startup the Plant as soon as reasonably practicable after Mechanical Completion has been achieved.

7.2Substantial Completion and Threshold Tests:  At such time(s) as Kiewit believes the Plant is operating at sufficient capacity to meet the output levels required for Substantial Completion and subsequently, the Threshold, testing shall be conducted to confirm that the required levels of merchantable ethanol product are being produced at the Plant.  The testing to determine whether the output levels required for Substantial Completion and subsequently the Threshold have been obtained shall continue for a period of twenty (24) hours and shall be at a stable production rate for such period and shall otherwise meet the requirements set forth on Exhibit C.  A separate test shall be conducted to determine whether the output levels required for Substantial Completion and for the Threshold have been met, unless the parties mutually agree in writing otherwise, or unless the output levels required for both Substantial Completion and the Threshold have been met by a single test.

7.3Performance Test and Performance Guarantees:  Kiewit shall begin the Performance Test as soon as reasonably practicable after the Threshold has been achieved.  Kiewit shall cause the Plant to meet or exceed the Performance Guarantees set forth in this Section 7.3 while demonstrating at the time of the

17

final Performance Test that the Plant meets all requirements of the Air Permit issued for the Plant.  All quantities set forth below are based on average quantities over the period of the applicable Performance Test.

7.3.1       Anhydrous Undenatured Ethanol Production Guarantee

Anhydrous Fuel Ethanol Production Rate:	Minimum *** US undenatured gallons per hour (average) based on a minimum feedstock specification of *** lb/bushel test weight corn containing a maximum of *** moisture (by weight), a minimum of *** dry fermentable starch (by weight) and a maximum of *** foreign material (by weight).
	When blended with the proper denaturant, denatured ethanol will meet specifications for fuel ethanol per ASTM D4806-06.
Anhydrous Fuel Ethanol Yield:	Minimum *** pounds un-denatured fuel ethanol per pound of dry fermentable starch (average) in corn feed based on a minimum feedstock specification of *** lb/bushel test weight corn containing a maximum of *** moisture (by weight), a minimum of *** dry fermentable starch (by weight), and a maximum of *** foreign material (by weight).

7.3.2       Utility Consumption Guarantees

Natural Gas. Maximum *** BTU HHV per gallon (average) of un-denatured fuel ethanol produced for gas-fired boilers and gas fired ring dryers based on natural gas provided at a minimum gas quality of *** BTU per standard cubic foot (1atm, 70° F), and *** to *** maximum (weight) DDGS moisture content.

18

7.4Condition to Performance Guarantees.  If any breach of warranty under this Contract or failure to meet the Performance Guarantees under this Contract is the result of:

7.4.1       The feedstock provided by Owner, not being in compliance with the conditions described in Section 7.3.1 or 7.3.2, as applicable;

7.4.2       Abuse, or poor maintenance, of the Equipment;

7.4.3       Owner’s failure to fulfill any of its obligations, which individually or in the aggregate are material, under the Performance Test protocols set forth in Exhibit C;

7.4.4       Owner’s failure, in any material way, to operate the Plant in accordance with the operating manuals and instructions provided by Kiewit;

7.4.5       Owner designing or procuring equipment and systems, other than under this Contract, that fail to meet Delta-T’s basic process design specifications for energy efficiency;

7.4.6       Owner fails to provide electrical service with at least a 0.85 power factor;

then Kiewit shall notify Owner, Owner shall take the necessary corrective actions and the affected Performance Tests shall be re-run at Owner’s expense.  However, if Owner refuses or fails  to provide the requested items, then Kiewit shall have no obligation or liability for any such breach of the applicable warranty or Performance Guarantees under this Contract.

7.5Substantial Completion:  Substantial Completion shall be achieved when the requirements for Substantial Completion in Exhibit E have been satisfied.  Kiewit shall provide Owner a certificate of Substantial Completion certifying that all requirements for Substantial Completion have been met at the time when all requirements for Substantial Completion have been achieved.  Owner shall have three (3) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Substantial Completion has been achieved.  Owner shall specify in detail any requirements for Substantial Completion which it believes

19

Kiewit has failed to achieve within seven (7) Business Days after receipt of such certificate.  Substantial Completion shall be deemed to have occurred on the date when the last of the requirements for Substantial Completion has been achieved.  Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach Substantial Completion; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve Substantial Completion; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

7.6          Cure:  After Substantial Completion (at which point care, custody and control transfers to Owner in accordance with Article 13), Owner shall allow Kiewit reasonable access to the Plant.  After reaching Substantial Completion, Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach the Threshold; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Threshold; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

After reaching the Threshold, Kiewit shall, for a period of up to six (6) months thereafter and subject to Section 16.1, (i) use good faith efforts to  cause the Plant to satisfy the Performance Guarantees in Section 7.3 and to re-run the Performance Tests as needed during that period; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Performance Guarantees; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects, and (ii) complete all Punch List items to the reasonable satisfaction of Owner.  Kiewit shall have the foregoing period of time in which to satisfy the obligations in the preceding sentence before being subject to paying any liquidated damages.

20

Kiewit is obligated to continue all aspects of the Work necessary to achieve completion of Performance Tests, Substantial Completion, the Threshold, and Final Acceptance (and in connection therewith, Kiewit is obligated to expend all necessary funds, devote all necessary time, and provide or procure all necessary work, materials, labor and services), except as such obligation is limited by Section 16.1 below.  All cost and expense associated with meeting such obligation, including any necessary acceleration of the rate of work will, unless and except to the extent required in accordance with Article 6, be for Kiewit’s account.

7.7Liquidated Damages and Maximum Damages for Performance Guarantees:  If the Plant has achieved Substantial Completion and Threshold, but has not achieved one or more of the Performance Guarantees set forth in Section 7.3 above during a Performance Test as provided herein, and Kiewit has not been able to correct the defect and pass all components of the Performance Tests within the time set forth at Section 7.6 above, then Kiewit shall pay to Owner liquidated damages based on the net amount (i.e. the amount of damages in each case for which damages apply shall be netted against the countervailing factor in each case for which the countervailing factor applies, to determine the final net performance liquidated damages if any) due as set forth in Section 7.8 below up to a maximum cumulative amount in accordance with Article 16 of the General Conditions of this Contract.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, except as such obligation is limited by Section 16.1.  For the avoidance of doubt, the countervailing factors shall not be taken into account for the purposes of determining whether Substantial Completion or the Threshold has been achieved.  Kiewit shall pay such liquidated damages no later than the date that is six (6) months after the achievement of the Threshold.

The sum of the countervailing factors, determined as set forth under Section 7.8 below, shall be deducted from the sum of the damages determined thereunder.  In no case, however, shall Owner have any obligation to pay Kiewit as a result of such calculation.  If the countervailing factors are greater than the damages, the performance liquidated damages shall be deemed to be zero.

21

7.8Amount of Damages and Countervailing Factors

Fuel Ethanol Yield:

$*** per *** pounds of anhydrous undenatured ethanol (average per ASTM D4806-06) per pound of dry fermentable starch that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Yield listed in Section 7.3.1 above. To the extent the yield is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall be a countervailing factor. For purposes of calculating damages as set forth above, damages shall be measured in increments of .001. An increment of .0005 or less is rounded down. An increment of .0006 or above would be rounded up.

Fuel Ethanol Production Rate:

*** per 10 US gallons per hour of anhydrous undenatured ethanol (average per ASTM D4806-06) that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Production Rate listed in Section 7.3.1 above. To the extent the rate is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall not be a countervailing factor.

Natural Gas Consumption: *** ***

7.9Damages Reasonable:  The Parties acknowledge and agree that the terms of this Contract with respect to liquidated damages, including those payable under this Article 7, are fair and reasonable considering the damage Owner would sustain in the event of the failure of the Plant to meet the Performance Guarantees set forth in Section 7.3 above, that such damages have been agreed upon and fixed as liquidated damages because of the difficulty of ascertaining as of the date hereof the exact damages that would be sustained by Owner, and that such liquidated damages provisions shall be applicable regardless of the actual amount of damages sustained.  All amounts shall be paid as liquidated

22

damages and not as a penalty.  The Parties specifically waive the right to challenge the liquidated damages rates and limits provided herein.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, subject to the limitations set forth in Section 16.1.

7.10Performance Bonus:  Upon Final Acceptance, Kiewit and Owner shall cooperate during a six-month bonus period of operation.  Owner agrees to pay to Kiewit a bonus of $*** for each *** above *** of Nameplate, capped at a bonus of $***; provided that the Plant meets the requirements of all applicable permits required for the operation of the Plant on a continuous basis (e.g. if there is an annual limit on emissions, the operation of the Plant at the levels during the applicable period, if operated on a continuous basis for a year, would meet the applicable annual emissions requirements).  Kiewit has six (6) months from Final Acceptance to achieve this bonus.  The bonus shall be determined by reviewing operating data on rolling two-week periods commencing on the date of Final Acceptance.  Bonus shall be payable thirty (30) Days after achieving these bonus criteria.

7.11Training of Owner’s Personnel:  Kiewit shall provide the training described in Exhibit A.  Owner shall provide appropriate personnel, and Kiewit shall provide such training, at times mutually agreed by them, commencing prior to Commissioning in sufficient time to prepare Owner’s employees to perform Commissioning and Startup and to perform their obligations with respect to the Performance Test.

7.12Use of Plant Prior to Final Acceptance:  Owner may use the Plant for commercial purposes on or after the achievement of Substantial Completion.  If Owner elects to use any portion of the Work for commercial purposes prior to Final Acceptance, it shall allow Kiewit reasonably unrestricted access to the Plant to do all things required to be done to complete the Punch List and achieve Final Acceptance and to meet full Performance Guarantees, as long as such access does not unreasonably interfere with Owner’s use of the Plant for commercial

23

purposes.  In the event Owner fails to comply with its obligation to provide Kiewit access to the Plant as set forth in the preceding sentence, (i) for each day that Owner so fails to provide such access, Kiewit shall have an additional day to satisfy its obligations hereunder which were adversely affected by Owner’s failure to so provide such access and (ii) if such failure to so provide such access is for an aggregate of thirty (30) days, then at the end of such thirty (30) aggregate day period, if Final Acceptance has not yet occurred, the matters set forth in items (i), (ii) and (iii) of the definition of Final Acceptance shall be deemed to have occurred.

7.13Final Acceptance:  Kiewit shall provide Owner a certificate of Final Acceptance certifying that all requirements for Final Acceptance have been met at the time when all requirements for Final Acceptance have been achieved.  Owner shall have ten (10) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Final Acceptance has been achieved.  Owner shall specify in detail any requirements for Final Acceptance which it believes Kiewit has failed to achieve.  Final Acceptance shall be deemed to have occurred on the date when the last of the requirements for Final Acceptance has been achieved.

8.Price and Payment

8.1Contract Sum:  Owner will pay Kiewit for the full and satisfactory completion of the Work the Contract Sum of ***, or such other sum as may be adjusted in accordance with this Contract, plus Excluded Taxes required under applicable laws to be paid or remitted by Kiewit in connection with the Work.  Owner shall be credited against the Contract Sum with all amounts paid by Owner or its affiliates under the AWA  and the Pre-EPC Agreement.  The Contract Sum includes the cost of materials and Equipment described in the AWA and the Pre-EPC Agreement to the extent such materials and Equipment are incorporated into the Work.  In addition, the Contract Sum includes  allowances for each of the matters (and for the amounts) set forth on Exhibit P.  The Contract Sum shall be adjusted for (a) preliminary site Work and piling Work according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such preliminary site Work and piling Work plus a

24

markup of *** and (b) all other Work set forth on Exhibit P (i.e. other than preliminary site Work and pilings Work) according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such Work (without any markup).  All matters covered under the AWA and Pre-EPC Agreement are superseded by the provisions of this Contract and are covered hereby.  The license fee to be paid by Owner under the License Agreement shall be paid by Owner directly to Delta-T and is not included in the Contract Sum.  If the Notice to Proceed is  provided more than ninety (90) days after the execution date of this Contract, the Contract Sum and the Guaranteed Substantial Completion Date shall be subject to equitable adjustment in accordance with Article 6.

The Contract Sum does not include Excluded Taxes.  Excluded Taxes means any: (i) taxes imposed by any Governmental Entity on the gross receipts earned by, or paid to, Kiewit on the Contract Sum or any other amounts to be paid by Owner to Kiewit hereunder or any portion of such amounts thereof, (ii) sales or use taxes imposed on Kiewit or any of its Subcontractors for purchases or sales of Equipment or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site or (iii) any property taxes imposed directly or indirectly by any Governmental Entity on the Plant, Equipment, or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site; provided, however, Excluded Taxes do not include any tax based on the income of Kiewit or its Subcontractors, such as the Indiana adjusted gross income tax (IC § 6-3-14, et seq.).  If Kiewit or any of its Subcontractors are, now or in the future, required to collect from Owner or pay any Excluded Taxes with respect to all or any part of the Work (other than any such tax based on income), then that amount shall be paid by Owner at Kiewit’s request, in addition to the Contract Sum.  Kiewit shall (and shall make a good faith effort to cause its Subcontractors to) cooperate with and provide reasonable assistance to Owner in obtaining any exclusions, exemptions or credits from any Excluded Taxes and to minimize said Excluded Taxes.  Owner shall hold harmless, defend and indemnify Kiewit and its Subcontractors for, and reimburse to Kiewit or any of its Subcontractors, any Excluded Taxes, interest or penalties associated therewith, or any other amounts, that must be paid by Kiewit or any of its Subcontractors as a result of an assessment or other action by a Governmental Entity as the result of Kiewit’s or

25

Kiewit’s Subcontractors’ reliance upon Owner’s claims of entitlement to any exemptions or reductions of Excluded Taxes.  Upon Kiewit or any of its Subcontractors receiving any such assessment or notice of any such other action by a Governmental Entity, Kiewit shall, and shall cause its Subcontractors to, promptly notify Owner of same.  Upon Owner’s receipt of such notice from Kiewit or its Subcontractors, Owner shall undertake the defense of any such assessment or other action by the applicable Governmental Entity, and Kiewit shall, and shall cause its Subcontractors to, cooperate with Owner in such defense.  Owner shall have the right to control such defense of any such assessment or other action by the applicable Governmental Entity.  A preliminary listing of available tax exemptions and concessions expected to be applicable to or available to the construction or operation of the Plant is attached hereto as Exhibit Q.

If Kiewit or any of its Subcontractors are required by applicable laws or are otherwise required to pay Excluded Taxes, Kiewit shall include requests for payment or reimbursement of such Excluded Taxes with Applications for Payment, the Final Payment, or any time within ninety (90) Days of a requirement by a Governmental Entity to pay such Excluded Taxes.

8.2Termination Fee:  In the event that Owner exercises a right to terminate under Section 9.4, or in the event that Kiewit terminates this Contract under Section 9.3 (provided the suspension of the Work which resulted in such termination by Kiewit does not include a suspension due to a Force Majeure Event),  the Owner shall pay in addition to sums due under Section 9.4 of the General Conditions, a fee determined as follows, as a liquidated damage for lost opportunity cost and not as a penalty: 

Termination:	Termination Fee as a Percentage of Total Contract Sum
Within Ninety (90) Days after the Date of Commencement	***
From Ninety-one (91) to one hundred fifty (150) Days after the Date of Commencement	***
From One hundred fifty-one (151) to two hundred ten (210) Days after the Date of Commencement	***

26

8.3Payment Terms:  Owner shall provide a mobilization payment to Kiewit in accordance with and at the times set forth in Exhibit B.  Owner shall make monthly progress payments according to percentage of completion beginning with and including payments made for work done under the AWA or Pre-EPC Agreement as set forth on Exhibit R, which payment schedule shall reflect the concept of “cash neutrality”.  For purposes of this Contract, “cash neutrality” shall mean that Kiewit will not be required to be out of pocket at any time for any amounts owed by Kiewit for the Work and that Kiewit shall not be paid by Owner for the Work in advance in such a manner that would result in Kiewit being cash positive as reasonably estimated by Owner and Kiewit. In the event the payment schedule set forth on Exhibit R conflicts with the foregoing definition of Cash Neutrality, the parties agree to conform said exhibit accordingly.  Kiewit shall submit Applications for Payment in the form set forth at Exhibit B.1, together with reasonable supporting documentation for said Application, to Owner.  Owner shall, through Owner’s Representative, sign the Certificate for Payment set forth on the Application for Payment for the full payment applied for, unless it believes that all or any part of such amount is not then due.  If Owner believes all or part of the amount requested in the Application for Payment is not then due, Owner shall amend the Application for Payment contained therein by indicating the amount, if any, that it believes to be due, and shall sign the application as amended and deliver the certificate, together with written notice of Owner’s reasons for certifying less than the whole amount applied for.  Retainage for each payment shall be *** for a 108 MGY plant; provided however, that Kiewit may provide an adjustable and irrevocable letter of credit in lieu of retainage in a form reasonably acceptable to Owner.  There shall be no retainage for Equipment that was the subject of the AWA.    In addition, upon payment of *** of the Contract Sum (excluding payments for Equipment that was the subject of the AWA), and provided Kiewit is in material compliance with this Contract, there shall be no retainage on any further payments under this Contract.  Upon reaching the Threshold, and provided Contractor is in  material compliance with this Contract, Owner shall release the retainage in exchange for Kiewit providing Owner a letter of credit for an amount equal to *** of the agreed upon estimated value of the

27

cost of completion of Punch List items plus any potential liability of Kiewit for liquidated damages.  Owner shall wire transfer, in immediately available funds, all amounts for which it has issued certificates, within fifteen (15) Business Days of the date of its receipt of the Application for Payment, to a bank account to be selected by Kiewit.  If Owner does not certify payment in the amount of the Application, and Kiewit and Owner cannot agree on a revised amount within five (5) Business Days of the date of the Owner’s submittal of the amended Application for less than the full amount, then either Party may commence the Dispute Resolution process in accordance with Article 18.  In any case, when the reasons stated by Owner for withholding payment of any amount for which an application has been made are removed to Owner’s reasonable satisfaction, in whole or in part, Owner shall immediately issue a Certificate for Payment for the amount withheld (to the extent the reason stated for withholding is removed) and make payment, via wire transfer as described in this Section 8.3, of the amount so certified on or before the date that the next payment is due.

8.4Late Payment:  Late payments by either Party shall bear interest at the rate of Wall Street Journal prime rate plus two percent (2%).

8.5Mechanic’s Lien Waivers and Indemnity:  Kiewit shall pay promptly for all amounts due for all materials, labor, Service and Equipment used in or in connection with the performance of this Contract, including those of its Subcontractors, when bills or claims become due, and shall indemnify and hold harmless Owner from and against all claims of its Subcontractors.  Owner shall give Kiewit prompt notice of any such claim upon receipt by Owner of any such claim.

8.6Mechanic’s Liens:  Kiewit shall keep the Plant Site and any other adjacent real property owned or leased by Owner and all other property of Owner which is located on the Plant Site or such adjacent real property, free and clear of laborer’s, materialmen’s and mechanic’s or similar type liens arising out of the performance of the Work, unless Owner fails to make required payments to Kiewit as set forth in this Article 8 and then only to the extent Owner has failed to make such payments.  Owner shall promptly notify Kiewit in writing of any lien so

28

arising of which it has notice or knowledge.  Kiewit shall provide to Owner as a condition to payments to be made pursuant to Article 8, a partial release of lien in the form of Exhibit B.2.1 duly executed by Kiewit and any major Subcontractors (those with subcontracts having a value of over $500,000) and shall also obtain and timely provide a complete release of lien and general release with respect to any such subcontract for which full and final payment is made, in the form of Exhibit B.2.  In each case, the release of lien may be for an amount less amounts that will be paid from the payment for which such release of lien is requested.  Kiewit shall promptly pay each Subcontractor upon receipt of payment from Owner of the amount invoiced that is undisputed and due to such Subcontractor.

If notwithstanding the foregoing, a lien is attached to the Plant, or the Plant Site, or any part thereof, without limiting any other rights of Owner, Owner shall have the right, at its option, to take all action reasonably necessary to discharge such lien upon thirty (30) days prior written notice to Kiewit of such lien.  Kiewit shall reimburse Owner for all amounts expended by Owner to obtain such discharge, including all costs and attorney’s fees and expenses and Owner shall have the right to deduct such amounts from payments otherwise due to Kiewit which will be debts due and payable by Kiewit to Owner.

8.7Final Payment:  Kiewit shall invoice Owner for the final amount due to it under this Contract upon reaching Final Acceptance.  Payment of all of the Contract Sum remaining unpaid, and any and all other amounts owing to Kiewit under the Contract (less and except any amounts owed by Kiewit to Owner), shall be made within thirty (30) Days after Final Acceptance and receipt by Owner of a final invoice; provided, that such payment shall not become due until Kiewit submits to Owner an affidavit in form and substance reasonably satisfactory to Owner that all payrolls, undisputed amounts owed to Subcontractors, suppliers and materialmen and any other indebtedness which might be or give rise to a lien against the Plant or the Plant Site arising out of performance of the Work or any portion thereof have been paid.

29

8.8Effect of Payment

No payment, final or otherwise or verification under this Article 8, shall constitute a waiver of claims by Owner or constitute or be deemed an acceptance, in whole or in part, of any portion of the Plant not in accordance with this Contract.

Upon receipt by Kiewit of payment in respect of the final Application for Payment pursuant to Section 8.7 (“Final Payment”), Kiewit releases Owner from any claim for payment for the Work.  For the avoidance of doubt, the sums paid to Kiewit in respect of its final Application for Payment pursuant to Section 8.7 shall constitute a valid and binding Final Payment for the purposes of this Section 8.8.

8.9Set-Off

Owner may deduct from moneys otherwise due to Kiewit:

(i)any debt or other moneys due from Kiewit to Owner in relation to the Contract; and

(ii)any claim to money which the Owner may have against the Kiewit whether for damages (including liquidated damages) or otherwise, under this Contract or otherwise at law relating to the Work.

9.Rights of Owner and Kiewit to Suspend Work or Terminate

9.1Owner’s Right to Terminate For Cause:  Owner may terminate this Contract if Kiewit commits or is subject to (a) voluntary bankruptcy, liquidation, reorganization or insolvency; (b) involuntary bankruptcy liquidation, reorganization or insolvency; (c) false or materially misleading representation or warranty; (d) assignment or transfer without permission; (e) failure to maintain insurance coverage as required; (f) failure to comply with any applicable law or permit; (g) cessation or abandonment of the Services (unless due to an emergency and then only for the duration necessitated by the emergency or due to Owner’s failure to make payment as required); (h) failure to supply sufficient skilled workers or suitable materials and equipment; (i) failure to achieve Substantial Completion within one hundred eighty (180) Days of the Guaranteed Substantial Completion Date; (j) failure to perform or observe any other material provision of this Contract; or (k) termination or repudiation of the EPC Guaranty

30

or voluntary or involuntary bankruptcy or insolvency of the guarantor under the EPC Guaranty; and, in the case of (c), (e), (f), (g), (h), or (j), Kiewit fails to cure such breach within thirty (30) Days (or such longer period (not to exceed one hundred eighty (180) Days) in the case of (e), (f), (h) or (j)) from written notice of such breach as may be commercially necessary.

Upon such termination Owner may take possession of the Work completed by Kiewit or delivered to the Plant Site and all materials and Equipment at the Plant Site acquired for incorporation into the Work and owned by Owner or Kiewit, take assignment of all purchase orders and subcontracts related to the Work and complete the Work by whatever reasonable method Owner may deem expedient.  Owner shall permit Kiewit access to the Plant Site after such termination as reasonably required by Kiewit to remove any equipment, trailers, supplies, goods and materials maintained by Kiewit in connection with the Work but not intended to be incorporated into the Plant, or owned or used by any of its Subcontractors under subcontracts not to be assigned to Owner.  In the event of termination for any of the reasons set forth above, Kiewit will be liable to Owner for any reasonable costs incurred by Owner to build the Plant as specified, in excess of the Contract Sum, up to a maximum of one hundred percent (100%) of the Contract Sum.  In case of such termination, the license granted under Section 2.4 above shall remain effective.

9.2Kiewit’s Right to Suspend Work:  If Owner does not pay Kiewit amounts that Owner has certified in writing for payment by the date such payment is due, then Kiewit may, upon fifteen (15) Days written notice to Owner, suspend the Work until payment of the amount owing has been received.  If Kiewit suspends the Work under this Section 9.2, then Kiewit shall be entitled to a change order in accordance with Article 6.

9.3Kiewit’s Right to Terminate:  Kiewit may terminate the Contract on fifteen (15) Days written notice to Owner if the Work is suspended, without fault on the part of Kiewit or, any of its Subcontractors, for more than one hundred eighty (180) consecutive Days.  In such event the termination shall be treated as if it were a termination for convenience by Owner, in accordance with Section 9.4, except that no Termination Fee shall be owed under Section 8.2 if such suspension

31

which resulted in such termination included a suspension due to a Force Majeure Event.

9.4Termination for Convenience by Owner.  Owner shall have the right, in its sole discretion, to terminate this Contract for convenience by giving written notice to Kiewit, but in the event of such termination for convenience, Owner will not enter into a contract with another person or entity to construct the Plant.  Upon such notice Kiewit shall immediately stop work and take all necessary and prudent actions to protect and preserve the Work, and to minimize Owner’s costs in terminating the project at that stage of completion.  Upon such termination Owner shall pay Kiewit (a) all amounts then due to it under this Contract as of the date of termination, including all amounts completed but not yet invoiced, and including the portions, if any, of such amounts that would have been held as retainage in accordance with Section 8.3 (or shall release the letter of credit in lieu of retainage, or the Punch-list letter of credit as applicable),  (b) all unavoidable costs payable to Subcontractors, including, without limitation, fees for cancellation or breakage costs, and Kiewit’s costs of demobilization, and (c) a termination fee calculated as set forth in Section 8.2, but in no event shall the total of such amounts set forth in Paragraphs (a) - (c) above exceed the Contract Sum.  For this purpose, the amounts then due to Kiewit shall be deemed to be all amounts billed in accordance with Exhibit B up to the date of termination, plus the value of all goods delivered and services performed under this Contract and not billed as of the date of termination less any amounts which have been prepaid by Owner for said items.  In the event that the Parties cannot agree on the total amount due within thirty (30) Days of the date of Kiewit’s demand for payment hereunder and delivery by Kiewit to Owner of all backup documentation supporting the amounts claimed to be owed by Kiewit, either Party may initiate the Dispute Resolution process set forth in Article 18 below.

9.5Owner’s Right to Suspend.  Owner shall have the right, in its sole discretion to suspend work under this Contract for periods of time up to one hundred eighty (180) days individually and in the aggregate.  In such event, Kiewit shall be entitled to an equitable adjustment to the Contract Sum and to the Schedule in accordance with Article 6 herein, including, but not limited to, an adjustment for

32

costs of escalation for labor and materials, unless such suspension is due to the failure of Kiewit or its Subcontractors to act in accordance with Good Industry Standards in the performance of their obligations under this Contract.

required in order to comply with Kiewit’s obligations under the Contract, or as agreed under Article 6 above.

11.3.2     Approval Process:  If Exhibit A or the Schedule provides for approval by Owner of any document, then, Owner shall be deemed to have given its approval unless it delivers written notice of its disapproval, and the specific reasons for its disapproval within the time allowed according to the Exhibit or Schedule, or in the absence of statement of the time allowed, within five (5) business days of receipt of the document or written request for approval; In the event that the reason for disapproval by the reviewing Party results from failure of the other Party (“submitting Party”) to fulfill any of its obligations under this Contract, then the submitting Party shall correct the work or document requiring correction and resubmit it for review.  The reviewing Party shall have the longer of three (3) Business Days, or one-half the time allowed according to the applicable Exhibit or Schedule if such time is prescribed, for the initial review to approve or disapprove the resubmitted work or document, and it shall be deemed to have given its approval unless it delivers written notice of its disapproval, and the specific reasons for its disapproval, within that time. The review and resubmittal process shall continue in like manner until the submitted Work is approved.  In the event that any disapproval results from a cause other than failure of the submitting Party to fulfill any of its obligations under this Contract, the Guaranteed Substantial Completion Date and other relevant milestones shall automatically be extended as provided at Section 5.1 above.

35

(i) that Kiewit, particularly on large or fast-track projects, may not make final selection of some Subcontractors until later in the project, and (ii) that Kiewit has the right to select Subcontractors as long as such selection would not result in failure by Kiewit to satisfy the requirements of this Contract.  The subcontracting of any portion of the Work, as described in Exhibit A, shall not relieve Kiewit of responsibility for performance of the Work as provided therein.  Subject to the foregoing, Kiewit shall have the right to subcontract such portions of the Work (but not all of the Work) as it shall determine to be necessary to others which, in turn, shall have the right to subcontract such portions of the Work assigned to them, if any, as they shall deem necessary.

Kiewit acknowledges and agrees that:

(b)it will be liable to Owner for all acts, omissions and defaults of the Subcontractors (and those of the employees and agents of the Subcontractors) relating to, or in any way connected with, the Work, to the same extent as if they were the acts, omissions and defaults of Kiewit.

3.3Geotechnical Analysis and Foundation Basis

The Scope of Work is based upon Exhibit D, Site Geotechnical Report dated May 18, 2007 (the Geotechnical Report”). To supplement this preliminary analysis, the following comments are noted.

·The corn silos will likely be on piles

·Other areas of the plant are expected to be supported on native soil, geopiers, or to over excavate and re-compact.

Kiewit’s design also assumes no bedrock, or groundwater, other than as set forth in the Geotechnical Report, will be encountered, and deep foundations i.e. piles, geopiers, etc. will be used for the corn silo loads.  Other areas of the plant will use geopiers, over-excavated/re-compacted or native soil.  The design assumes that all soils can be excavated with small scrapers and used for fill.  The design does not provide for the handling or disposal of unsuitable soils, buried refuse or debris.  The design assumes that design soil compaction can be achieved using the existing site soils.  All subsurface conditions shall be considered to be consistent with native soils with no below grade obstructions.

A final geotechnical report shall be provided by the Owner, coordinated with Kiewit..  It shall include borings, samples and laboratory testing sufficient to determine the existing soil conditions for design and construction of the foundations and other specific features for all major equipment items including tanks, cooling tower, stacks, buildings, plant components, disposal facilities, and roads.  The report shall include recommendations for foundations, site surfacing/fill materials, and roadway fill.

Any differences between the final geotechnical report and the Geotechnical Report shall constitute a change (increase or decrease) to the allowances set forth in Exhibit P.

PERFORMANCE TEST PROTOCOLS

1.Performance Test Protocols

1.1Pre-Test Preparation

1.1.1Prior to the PERFORMANCE TEST, the Plant must have reached Mechanical Completion.  In addition, the OWNER must have run the Plant at or near design rate consistently for a period of ***, as evidenced by Plant operational data provided to KIEWIT by OWNER, before the PERFORMANCE TEST is initiated. This *** operating period may be reduced or waived upon the agreement of the KIEWIT Test Coordinator and the Owner Representative.  Before commencement of PERFORMANCE TEST, KIEWIT shall notify OWNER in writing at least *** prior to planned commencement of the PERFORMANCE TEST that all pre-test conditions have been satisfied, including the following:

·Adequate and competent supervision, personnel and resources for effective operation, maintenance and performance analysis of the Plant, including laboratory analysis, temporary meters or other measuring devices and instrumentation specified as to accuracy and reproducibility by KIEWIT in advance of the PERFORMANCE TEST required to conduct and evaluate the PERFORMANCE TEST shall have been furnished.  The Plant shall be operated and maintained in accordance with the technical advice and instruction from the Operations Manual and on-site directives from KIEWIT, and otherwise within generally accepted practices within the fuel ethanol industry.

·The Plant, its machinery, equipment, instrumentation and piping, shall all be clean lubricated where appropriate, leak tight, and ready to operate according to design specifications.  All systems and appropriate checkouts and calibrations shall have been completed and documented by responsible Plant technicians, contractors, and/or vendors.  Analytical and any special test equipment and reagents will have been calibrated and made accurate.

·Cleaning (CIP) of the process equipment has been accomplished *** or less before the PERFORMANCE TEST per KIEWIT direction and standard procedures set out in the KIEWIT Operations Manual. This requirement to CIP within *** may be reduced or waived upon the agreement of the KIEWIT Test Coordinator and the Owner Representative.  All ingredients and supplies required to complete the test are on hand.  This includes, but is not limited to, feedstock of corn (meeting specifications listed in Article 7 Section 1.2) supplied in stable quantities sufficient to support Plant operation at a rate up to *** of the guaranteed fuel ethanol production rate, as well as sufficient steam, water, stable permanent power, and other utilities, enzymes, chemicals, and other ingredients of the type specified by KIEWIT in the Operations Manual and supplies to support Plant operation at a rate up to *** the guaranteed fuel ethanol production rate.

·Adequate operation, analytical, and maintenance support shall be scheduled for the test period.

1

1.2Coordination

1.2.1KIEWIT shall coordinate the PERFORMANCE TEST with OWNER during the *** PERFORMANCE TEST period.  This coordination of the PERFORMANCE TEST activities will be handled by a KIEWIT Representative designated to serve as KIEWIT’s Test Coordinator (“Test Coordinator”).  The Test Coordinator will work with an individual designated by the OWNER to be its Representative for the PERFORMANCE TEST to set the test schedule and to coordinate operations during the test period. KIEWIT will also assign KIEWIT Shift Coordinators to support the operation during the test period.

1.2.2OWNER shall supply, or cause to be supplied, all feedstock, utilities and other supplies and services required to conduct the PERFORMANCE TEST, as specified under Section 1.1.1 above, throughout the entire Plant during all PERFORMANCE TESTS.

1.2.3OWNER shall direct its personnel in the operation of the Plant in a manner consistent with the operating parameters provided in the Operations Manual.  Owner’s personnel shall be under the direction of Kiewit.

1.3Conducting the Test

1.3.1The KIEWIT Test Coordinator shall be provided with operating data by the OWNER sufficient to verify that the Plant is operating at a condition suitable for initiation of the PERFORMANCE TEST.  At the scheduled start time of the PERFORMANCE TEST, the KIEWIT Test Coordinator will signal that the test has formally begun and will direct operators to take the initial test measurements. The test will be conducted over a *** period of operation.  During the Test period, the Plant shall be operated by the OWNER in compliance with the KIEWIT Operations Manual and instructions provided by KIEWIT, including, without limitation, adjustments in temperatures, pressures, feedstock rates, steam flow, and other process control inputs, provided these adjustments do not result in unsafe operating conditions.  Plant operators will monitor and record operating data according to standard procedures and in addition will record the supplemental data specified in this protocol on data sheets in the form to be provided by KIEWIT.  Records will be developed from permanent Plant equipment that is calibrated immediately prior to test.  All test measurements will be reviewed by the Test Coordinator (or a designated Representative) and OWNER.  If the Test Coordinator or the Owner Representative believes that there might be a problem with the measurement method or reading, the reading will be retaken and verified by the Test Coordinator and OWNER’S Representative. Immediately upon the conclusion of the PERFORMANCE TEST, the Test Coordinator will meet with Representatives of OWNER to review the test results.  KIEWIT and OWNER shall each be given a copy of the test results.  If the Performance Guarantees have been met, then OWNER shall promptly issue a notice to KIEWIT to such effect.  If the PERFORMANCE TESTS have not been met, then OWNER shall issue a written notice to KIEWIT within *** of completion of the PERFORMANCE TESTS indicating in what manner such Performance Guarantees have not been successfully completed.

1.3.2If the *** test period is interrupted for any reason within KIEWIT’s control or OWNER’S control, a new *** test period will resume after the cause for the interruption has been corrected and the Plant has achieved an acceptable operating capacity at substantially the same rate immediately prior to the interruption.  KIEWIT and OWNER shall stop the PERFORMANCE TEST if it becomes obvious that it cannot be carried to a

2

satisfactory conclusion in the current attempt.  If the PERFORMANCE TEST has been interrupted for reasons not attributable to  KIEWIT, and continues to be interrupted such that KIEWIT has spent a cumulative period of *** on site since the commencement of the test, then OWNER shall compensate KIEWIT for the personnel that KIEWIT has on site.  This compensation period shall begin on the *** on site, and will continue until the completion of the PERFORMANCE TEST.  This compensation will cease should the inability to complete the PERFORMANCE TEST be the fault of KIEWIT.  Compensation rates shall be at Kiewit’s standard rates.

2.	Analytical/Calculation Protocols
2.1	Undenatured Fuel Ethanol Quality
	METHOD:	Analyze samples according to ASTM D4806-06. The last test result before emptying day tank into main storage tank shall determine the quality for the batch. The average of all batch test results over the test period shall be used in determining the quality for the PERFORMANCE TEST. If required, a separate sample may be denatured with *** denaturant and the tests repeated to ensure ASTM D4806-06 is met.
		If the fuel ethanol in the day tank does not meet the quality specifications of Article 7, KIEWIT has the discretion to send it on to the main storage tank (on the theory that the blended product in the main storage tank will meet the quality specifications) the average of all batch test results shall be used to establish the blended quality. If the blended fuel ethanol does not meet quality specifications as a result of below quality product measured in one or more day tank batches the volume of the batch(s) shall not be included in ethanol production “rate” quantities used in calculating liquidated damages.
	SAMPLE POINT:	Undenatured Fuel Ethanol Day Tank Storage
	SAMPLE SIZE:	***
	SAMPLE CONTAINER:	Nalgene
	FREQUENCY:	Once per ***
	SAMPLES RETAINED:	All
	PREPARATION:	Standardize test reagents. Clean glassware and sample containers. Assure that reagents are of sufficient quality.
	DOCUMENTATION:	Log results on a PERFORMANCE TEST Data Sheet.

2.2	Undenatured Fuel Ethanol Production Rate
	METHOD:	The day tank will be manually measured every *** to serve as the principal method of measurement of production volume, along with a final measurement of the day tank before the contents are sent to the main storage tank(s). In addition, flow totalizer readings will be taken from product meter or other measuring device mutually agreed upon between OWNER and KIEWIT at regular intervals as backup verification of the manual measurements. The total quantity of ethanol produced will be adjusted to a volume equivalent ethanol per ASTM D4806-06. Divide by the total number of test hours to determine the average rate over the test period
	SAMPLE POINT:	Product volumetric totalizing meter (with computer monitoring) after Product Receiver.
	SAMPLE SIZE:	N/A
	SAMPLE CONTAINER:	N/A
	FREQUENCY:	Once per *** and at the end of each Day Tank batch.
	SAMPLES RETAINED:	N/A
	PREPARATION:	Certify that the flow meter is properly calibrated.
	DOCUMENTATION:	Log results on a PERFORMANCE TEST Data Sheet and sign off by the OWNER and KIEWIT.
2.3	Undenatured Fuel Ethanol Yield
	BASIS:	See Section 7.3.1 Anhydrous Fuel Ethanol Yield of the General Conditions.
	METHOD:	Record corn-weigh belt totalizer readings to measure the accumulated meal weight. Measure the sample moisture and starch content. Convert total undenatured ethanol volume from the Rate Test to weight at 60oF. Divide the calculated mass quantity of undenatured ethanol by the calculated corn mass quantity of total starch fed over the time period to determine yield. In addition, this weigh belt total should be cross checked by totaling all corn receipts, subtracting all foreign material content, and taking into account the current corn bin volumes. OWNER and KIEWIT shall mutually agree on the method for the testing of dry fermentable solids.
	TEST POINT:	Corn weigh belt
	FREQUENCY:	Once per ***
	PREPARATION:	Certify that the weigh belt is properly calibrated

4

	DOCUMENTATION:	Log results on “PERFORMANCE TEST Data Sheet”
2.4	Natural Gas Consumption
	METHOD:	Record Plant natural gas meter totalizer readings in MCF over test period. Obtain high heat value specification for gas from the utility providing natural gas to the site over the test period and calculate the BTU over the test period. Divide this value by the amount of undenatured ethanol produced during the test period to determine BTU per gallon of undenatured ethanol produced during the test period. Average results of all calculations for test period to determine natural gas consumption value for Performance Test.
	TEST POINT:	Plant gas meter
	FREQUENCY:	Once per ***
	PREPARATION:	Certify gas meter is properly calibrated and suspend all non-process use of natural gas. The gas meter shall be pressure and temperature compensated in accordance with the local gas company standards.
	DOCUMENTATION:	Log results on an “Performance Test Data Sheet.”

2.5Air Emissions

Testing shall be performed in compliance with the stricter of all applicable requirements of the USEPA and IDEM.

2.6Calculation Protocol

All calculations will be based on actual measured data taken during the test period.  For any given sample period, the average value during that period will be determined by the average of the measured data points for that sample period.  The liquidated damages, if any, will be determined using the data collected for each individual sample period and averaged over the PERFORMANCE TEST period. All samples shall be taken in duplicate and OWNER and KIEWIT shall each retain one sample.  OWNER shall analyze one of the duplicates; the second shall be reserved for use in case of a disagreement.  OWNER shall cause such analyses to be conducted at the Plant during the PERFORMANCE TEST period and in the presence of the Test Coordinator or such coordinator’s designee, and OWNER, and Lender’s designated representative, if applicable, if they are present; provided, however, if equipment for such testing is unavailable at the Plant the sample will be sent to an outside laboratory reasonably acceptable to OWNER and KIEWIT for analysis.  In case of disagreement, a referee laboratory shall be selected by agreement between OWNER and KIEWIT, and the cost of such referee laboratory shall be paid by the Party or Parties not substantiated by the referee.  The findings of this referee laboratory shall be accepted as final.

1.0      EXECUTIVE SUMMARY

1.1      Purpose and Scope of Study

The purpose of this study was to explore the subsurface conditions at the site and to develop recommendations to aid in the design and construction of the proposed Ethanol Plant to be located at Mount Vernon, Indiana. More specifically, our work included:

1. Review of our previous assessments;

2.Site reconnaissance by a Geotechnical Engineer;

3.Seventy-seven (77) Standard Penetration Test (SPT) borings to explore the soil and groundwater conditions and to provide samples of the subsurface materials;

4.Deep cores at two (2) locations to characterize the shale and obtain samples of the same;

5.Observation of six (6) test pits to take into account the macrostructure of the surficial clayey soils;

6.Performance of in-situ geophysical surveys including thermal and electrical resistivity and shear wave velocity testing;

7.Laboratory tests conducted on samples obtained from the borings to evaluate the classification and engineering properties of the soil and bedrock; and

8.Engineering analyses of the field and laboratory test data to develop recommendations to guide design of foundation, pavement and floor slab support. We also developed recommendations regarding general construction procedures and identified potential construction problems.

In the body of this report, we present a summary of our findings, an interpretation of the subsurface conditions, our design recommendations and construction considerations. A Preliminary Foundation Parameters summary is presented in the Tables Appendix. Various figures are presented in the Figures Appendix. The field and laboratory operations, together with the soil boring and test pit logs, are presented in the Field Exploration Appendix. General Qualifications and Contractual Considerations are presented in the Qualifications Appendix. L-Pile and Driven Computer Program printouts are provided in the Calculations Appendix.

Guidelines for Auger Cast-In-Place (ACIP) Pile Specifications are provided in Appendix A. The geophysical survey results are provided in Appendix B.

1.2      Principal Findings

·The site is relatively flat with soft and wet ground surface conditions observed during the field operations.

·The geotechnical exploration reveals that the site is underlain by about 80 ft of clayey soils in turn underlain by sandy soils to the top of shale bedrock encountered about 130 ft below existing grade. The average groundwater depth was about 1 to 2 ft below the ground surface.

·The upper clayey soils are relatively low in strength allowing only lightly loaded shallow foundations and mats to be designed for 2,000 pounds per square foot (psf). Foundations should bear on an improved “crust” of lime stabilized soils.

·Fermentation, beerwell and ethanol storage tanks may be supported on the clayey soils provided vertical soil reinforcement (e.g., Geopiers) is incorporated in the upper 20 to 25 ft of the deposit and 3 inches of total settlement can be tolerated.

·The substantial loads exerted by the grain silos will require deep foundation support to reduce settlement. Deep foundations may include moderate capacity, 90 ft long auger cast piles or high capacity, steel H piles driven to bedrock.

·The geophysical survey confirms that this site seismically is a Class D.

·Floor, pavement and railroad areas should also be lime stabilized to facilitate earthwork operations and better define earthwork costs prior to construction.

·The high groundwater conditions encountered at the site are problematic and will require site filling and/or subsurface drainage.

2.0      SITE AND SUBSURFACE CONDITIONS

2.1      Site Location and Topography

The site consists of Areas B and C totaling an approximate area of 60 acres (see Figure 1). The site is also bisected by Southwind Port Road. The site surface was fairly flat with elevations generally in the 377 ft to 378 ft range. The site has been used to grow crops.

2.2      Site History

The site is currently occupied by the Indiana Port Authority, which leases the site for cropland to a local farmer. According to Mr. Bruce Willis of the Indiana Port Authority, the land has been utilized solely for cropland since 1959. The site was previously utilized for a small dirt runway for the municipal airport, dirt racetrack, and carnival on the westernmost portion in addition to farmland for an unknown period in the 1940s and 1950s, according to Mr. Bruce Willis. Prior to that, the site was used as cropland.

2.3      Site Conditions

2.3.1   Fall 2006

The fields contained fully grown corn prior to harvesting. The borings were located so as to reduce intrusion into the corn field and crop damage. Recent rains made the ground soft, but vehicles and equipment were still capable of maneuvering. No visual or physical access to interior portions of the field was possible due to the fully grown corn.

2.3.2   March 2007

The corn fields had been harvested leaving approximately 6-inch high stubble in the fields. The fields were very soft and yielding and had standing water over approximately 20 percent of the area from recent rains. The majority of the area that had standing water was on the west side of Southwind Port Road. Foot access was difficult due to soft ground surface conditions even at drier areas of the site. Even after a week of drying, four-wheel drive vehicles could not access the fields, though track equipment could with difficulty on the northeast quadrant of the site.

2-1

2.3.3   April 2007

The fields continued to have soft areas due to recent rains, but tracked and four-wheel drive vehicles were able to maneuver in the fields. Some areas (generally in the northeast portion of the site) had desiccation cracking in the upper approximate 1 to 4 inches of soil.

2.4      Geologic Setting

The site is located within the Wabash Lowland physiographic province. The province is underlain primarily by sandstone and shale of Pennsylvanian age and is characterized by broad, partly sediment filled valleys and rounded hills.

Thick lake and river sediments and outwash deposits overlie the bedrock in places. Along the Ohio River are broad, terraced valley-fill sediments. Unconsolidated soils at this site consist of two deposits, i.e., clayey overbank soils underlain by sandy valley train deposits. This sequence is common in the locale based on published information regarding the Atherton Formation. Overbank sediments are deposited on a valley floor outside of the stream channel. Such waters usually contain much sediment in suspension resulting in fine layers of clay/silt deposition. Valley train deposits are stratified drift from meltwater-fed, braided and overloaded streams, deposited within a confining valley.

In the area of Mount Vernon, Robinson (1977)1 maps the bedrock surface at an elevation of approximately 250 ft msl. With a land surface elevation of about 380 ft msl, this information suggests that the total thickness of unconsolidated soil is about 130 ft in the locale.

Underlying bedrock is primarily the lower part of the Pennsylvanian McCleansboro Group characterized by shale, sandstone, limestone, and thin coal. A fault trends from southwest to northeast along the west side of the prospective sites, beyond which bedrock is the middle part of the McCleansboro Group also characterized by shale, sandstone, limestone, and thin coal. Bedrock at deeper depths includes the Pennsylvanian Carbondale Group, Racoon Creek Group, and Mississippian rocks of the Chester Age, the Stephensport Group, West Baden Group, Blue

River Group, the Sanders Group, and the Borden Group. These rocks consist of alternating sequences of limestone, siltstone, shale, and sandstone (Gray, et al., 1970).2

2.5      Soil Conditions

Our interpretation of the subsurface conditions is based upon seventy-seven (77) drilled soil borings drilled, six (6) test pit excavations, and two (2) rock cores advanced at the approximate locations shown in Figure 2. Geophysical surveys also included electrical/thermal resistivity and shear wave velocity testing. Borings B-1 through B-4 and test pits TP-1 through TP-6 were located by pacing from existing site features while borings B-5 through B-77, by our surveying staff. All borings were drilled with all-terrain vehicle mounted equipment due to very soft and wet ground surface conditions. The following discussion is general; for more specific information, refer to the boring and test pit logs presented in the Field Exploration Appendix and the geological cross section shown in Figure 3.

The test pits, soil borings and rock cores extended to a maximum depth of 148 ft below existing grade at the explored locations. In general, topsoil, clayey soils, sandy soils and bedrock were encountered. The following provides additional information concerning each of these strata.

·Topsoil – This material was generally 6 to 12 inches thick (occasionally 18 inches thick), and encountered in all the borings and test pits. It is typically described as brown to dark brown clayey topsoil with organics. During test pit excavation, minor desiccation was noted in the upper 1 to 4 inches of topsoil during a period of dry weather.

·Clayey Soils – Below the topsoil, clayey soils were encountered to an average depth of approximately 80 ft below existing grade (elevation 300 ft ±). These are believed to be overbank deposits from ancient floods along the Ohio River. The clayey soils are typically brown to brown and gray in color occasionally becoming all gray or bluish-gray and consisted of low plasticity silty clays and lean clays. Layers of very loose to medium dense silts and clayey silts were interbedded within the clay matrix along with traces of organic material near the surface. The consistency of the silty/lean clays was generally

soft to stiff in the upper approximately 20 to 25 ft, stiff to very stiff to about 60 ft and becoming mostly medium to stiff thereafter. The unconfined compressive strength envelope shown in Figure 4 shows the lower end of this general strength trend. Transitional soils including loose silty or clayey sands were often encountered at the base of the deposit. The upper 4 to 5 ft of clayey soils examined during excavation of test pits readily caved in small portions. Within the test pits, the clayey soils below the depth of groundwater infiltration readily caved in larger portions which caused difficulties maintaining an open cut test pit.

·Sandy soils – Below the clayey soils, sandy soils believed to be valley train deposits were encountered. The sandy soils are generally described as brown to grayish brown in color, fine to coarse in texture and loose/medium dense near the surface becoming dense to very dense at the base. Variable amounts of silt and clay were encountered within the sand matrix, generally becoming less prevalent with depth.

·Bedrock – Below the above described sandy soils at depths ranging from approximately 128 to 136 ft below existing grade, bedrock was encountered. Where cored, the bedrock is described as dark gray clay shale. Standard Penetration Test resistance values near the weathered bedrock surface ranged from 50 blows per 1 to 5 inches of split-spoon penetration indicating a very dense condition. Rock quality designations ranged from about 24 to 30 percent indicating a very poor to poor3 in-situ rock quality.

2.6      Groundwater Conditions

Groundwater level readings obtained both during and after drilling operations are noted on the boring logs. Water levels ranging from approximately 0.4 to 5.7 ft were recorded after a waiting period of up to 5½ weeks; however, the average was generally in the 1 to 2 ft range for all of the borings that were drilled to varying depths (10 ft to 148 ft). This indicates that the encountered soils are likely saturated throughout their occurrence and little if any horizontal or vertical hydraulic gradients exist.

2-4

During test pit excavation, groundwater flowed into the pits starting at about 4 to 6.5 ft below ground surface. The majority of the water entered from the walls of the excavation, though some water was noted coming up from the bottom of the test pits. The largest amounts of water tended to enter through siltier portions of the clayey soils. Test pits generally filled with about 1 to 2 ft of water in 20 minutes.

In clayey soils, relatively long periods of time are usually required for the groundwater level to attain an equilibrium position in the boreholes. Therefore, long-term monitoring may yield different results. Additionally, seasonal fluctuations in the groundwater level may occur due to variations in precipitation, evaporation, and surface water runoff. Shallower water table conditions will likely occur during and after significant precipitation. Groundwater should be expected to rise to near the ground surface during the wet season and this should be assumed for design purposes.

2.7      Consolidation Tests

Nine, one-dimensional consolidation tests were performed on relatively undisturbed, 3 in. diameter, shelby samples of cohesive soils. The results of each individual test are presented as plots of vertical strain versus logarithm of vertical effective stress as shown in the Field Exploration Appendix.

Maximum past consolidation pressures (Pc) were determined from these curves. The test results are summarized below.

2-5

Boring	Depth (ft)	Description	Location	Preconsolidation Pressure-tons/ft2 (Pc)	Over- consolidation Ratio
B-7	16-18.5	Silty Clay to Clayey Silt	Ethanol Storage	1.2	2.4
B-8	21-23	Silty Clay	Ethanol Storage	3.25	5.0
B-11	66-66.5	Lean Clay	Ethanol Storage	5.5	2.8
B-19	20.5-21	Lean Clay	DDGS Storage	2.6	4.1
B-24	13.5-14	Lean Silt	Grain Storage	3.8	9.0
B-25	31-31.5	Lean Clay	Grain Storage	1.9	2.0
B-31	68.5-69	Silty Clay	Process Building	2.6	1.3
B-51	66.5-67	Lean Clay	Fermentation	4.0	2.0
B-58	35.5-36	Lean Clay	Future Fraction	8.0	7.4

Preconsolidation pressures were typically higher in the middle of the clayey soil deposit, decreasing towards the surface and base. The preconsolidation pressure envelope shown in Figure 4 shows this general trend. The preconsolidation pressure generally mirrors the unconfined compressive strength envelope and is higher by an multiplier of about 2.3 to 3.5, which is considered normal for low plasticity lean clays and silty clays.

2.8      Standard Proctor and California Bearing Ratio Testing

Two standard Proctor and California Bearing Ratio tests were conducted on bulk samples obtained from within the proposed roadway and railroad areas. The results are tabulated below:

2-6

Boring Location	Depth (ft)	Soil Description	Maximum Dry Density (pcf)4	Optimum Moisture Content (%)4	Natural Moisture Content (%)	California Bearing Ratio (CBR)
B-69	0.8-1.3	Lean Clay	106.5	18.3	23.3	3.8
B-75	0.8-1.3	Lean Clay	106.3	16.3	24.2	4.2

The natural moisture contents are about 5 to 8 percent higher than the optimum moisture contents which indicates that a substantial drying effort (or lime modification) will be necessary to facilitate compaction. We are currently running tests on a sample of the soil/lime mixture to measure potential strength gain and improved soil characteristics.

3.0      PROJECT INFORMATION

We understand that the proposed development consists of a 216-million gallon per year, dry mill Ethanol Plant (see Table 1 provided by Bibb & Associates for more information regarding foundation parameters). Buildings are planned to consist of one-story, high eave-height, steel-framed structures. Building column and wall loads are not anticipated to exceed 100 kips and 4 kips per linear foot, respectively (column loads for the boilers may reach 200 kips). Most of the main building structures will have conventional interior slabs-on-grade with individual foundations supporting equipment and tank loads. We expect the interior slabs-on-grade will be subjected to a maximum floor load of 200 pounds per square foot (psf), except for the DDG storage building where the floor load may reach 1,200 psf.

Large storage silo/tanks are also planned. The tanks are expected to consist of metal shells and floor with a concrete ringwall foundation (relatively settlement insensitive) while the silos will likely be slip-formed concrete cylinders supported on 2 to 3 ft thick, octagonally-shaped, reinforced concrete mat slabs (fairly settlement sensitive). The silo foundations typically extend about 6 to 10 ft below final grade and incorporate below grade tunnels and pits.

The plant design grade is still unknown, but we would expect that filling will be required to help alleviate problems associated with the high groundwater conditions. Other improvements will include paved parking and drive areas servicing the buildings. Allowable settlements specified by the designer are no more than 2.5 inches total (raised to 3 inches at large tanks) and 1 inch differential for tanks and silos, and 1 inch total and ½ inch differential for buildings.

4.0      DESIGN RECOMMENDATIONS

4.1Basis

Our recommendations are based on data presented in this report, which includes seventy-seven (77) widely-spaced soil borings, six (6) test pits, two (2) rock cores and a geophysical survey. Subsurface variations can exist on a site which may not be indicated by a dispersed exploratory boring program. We have also discussed our findings with local piling contractors, the Geopier Foundation Company and Dr. Safdar Gill, P.E., of Ground Engineering Consultants, Inc. If such variations or unexpected conditions are encountered during construction, or if the project information is incorrect or changed, we should be informed immediately since the validity of our recommendations may be affected. Refer to the Qualifications Appendix for additional Qualifications and Contractual Considerations.

On projects with fairly weak soil conditions and substantial loads such as those present at this site, discussions should continue between the Geotechnical Engineer, designer and contractor. In particular, as the design takes shape we can provide additional input on the selected foundation system and feasibility of various construction procedures.

4.2General Subsurface Assessment

Based on the results of field and laboratory testing, the following generalizations can be made.

·The upper approximate 20 ft of the clayey soil layer has relatively low strength [design unconfined compressive strength (Qu) envelope of 0.4 to 0.6 tsf]. These soils are capable of supporting relatively light building loads of 200 kips (1 inch of allowable settlement), and mat loads (2.5 inches allowable settlement) provided the upper surface is strengthened with lime to form a firm “crust.” Footings (less than 10 ft square) and tanks (less than 20 ft in diameter) may be designed for a maximum net allowable soil bearing pressure of 2,000 psf, provided the surface is adequately stabilized and the settlements can be tolerated.

·The 2,000 psf (1 tsf) bearing pressure will be attenuated by the lime stabilized crust so that plastic yielding of the soft to medium stiff clays will be reduced and the 1.4 tsf preconsolidation pressure (see Figure 4) will not be exceeded. Therefore, settlements

4-1

will be reduced. The lime stabilization cost can also be defined with more certainty prior to construction (rather than random undercutting).

·Foundation soils beneath footings/tanks exerting contact pressures 2,000 psf or higher will require additional improvement, likely vertical reinforcement such as geopiers.

·The fermentation, beerwell and ethanol storage tanks exert contact pressures of 4,000 psf, or 2 tsf. This pressure exceeds the design preconsolidation pressure of 1.4 tsf from 0 to 20 ft; therefore, large settlements are predicted to occur if this zone is not improved. Provided soil vertical reinforcement (e.g., Geopiers) is extended into the stiffer overconsolidated clays having preconsolidation pressures exceeding 2 tsf (deemed the “upper zone”), settlements are estimated not to exceed 3 inches total and 1 inch differential. This settlement is estimated to take approximately 3 years to complete (the “end of consolidation”).(5) Therefore, long-term settlements of the deeper clays (deemed the “lower zone”) are expected to occur relatively slowly and any necessary adjustments to piping hookup could be made in a timely manner, provided adequate monitoring is maintained. It is estimated that hydrotesting the tanks for a minimum period two (2) weeks will fully consolidate the upper zone and cause some settlement of the lower zone so that potentially one-half of the estimate settlement will be precipitated.

·The grain silos are 75 ft in diameter and exert a substantial contact pressure of 8,000 psf, or 4 tsf. Even considering geopier installation, over 5 inches of settlement is estimated. Therefore, deep foundations are recommended.

·Medium capacity, 18-inch diameter, 90 ft long auger cast piles and high capacity, large section H-piles (HP 14x117) driven to bedrock (135 ft ±) can be designed for allowable compression capacities of 100 and 300 tons, respectively. Pile settlement for the auger cast pile is estimated to be about 1-1.5 inches (which includes group effects) and the deep H-pile, about 1 inch. Due to the geological conditions encountered at the site, we prefer the deeper driven pile option.

4-2

More specific design recommendations for foundations, floor slabs, piles and ancillary aspects of the project are provided in Sections 4.3 through 4.11 below.

4.3      Shallow Foundations

4.3.1   General Building and Lightly Loaded Tank Foundations

In our opinion, the proposed ethanol plant building structures and lightly loaded tanks can be supported on shallow foundations. Foundations should be constructed in compliance with the recommendations for site preparation, fill placement, and inspection that are discussed in Section 5.0 of this report.

Due to the weak nature of the encountered surficial clayey soils, we recommend that Code L lime (or equivalent) be incorporated to a depth of at least 16 inches into the soil below footings. Code L lime, manufactured by the Mississippi Lime Company of St. Genevieve, MO, is commonly used for soil stabilization in the area. We are currently running tests on a sample of soil/lime mixture to measure potential strength gain and improved soil characteristics.

In our opinion, a maximum net allowable soil bearing pressure of 2,000 psf is achievable provided that the foundations bear on at least 16 inches of lime stabilized soil overlying the natural clayey soils, or on structural fill overlying the same. This value is that pressure which may be transmitted to the foundation soil in excess of the final minimum surrounding overburden pressure and may be increased by one-third when considering temporary wind or seismic loading conditions. This pressure is valid for column footing loads not exceeding 200 kips and width not exceeding 10 ft. Larger footings or mat foundations (maximum width of 20 ft) may also be proportioned for 2,000 psf provided a maximum total settlement of 2½ inches is tolerable. If this pressure or these widths are exceeded, then the installation of vertical soil reinforcement (e.g., Geopiers) will become necessary.

We recommend that wall and column footings should be at least 18 and 24 inches wide, respectively. In order to provide adequate frost protection, we recommend locating perimeter footings in heated areas of the structures at a depth of at least 1.5 ft below finished outside grade. In non-heated areas of the structures, the foundations should be located at a depth of at least 2.0 ft below finished grade. Interior footings in heated areas can bear at nominal depths below the finished floor.

4-3

In addition, each new foundation should be positioned so it does not induce significant pressure on adjacent new or existing foundations, otherwise the stress overlap must be considered in the design.

4.3.2   Fermentation, Beer Well and Ethanol Storage Tanks

The Geopier Foundation Company can design and construct a series of Geopiers under the proposed tanks. Geopiers consist of columns of highly compacted crushed rock which impart lateral stresses to the soil, thus reducing post-construction settlement with the use of conventional concrete ringwall/metal floor type foundations. Geopiers will be placed on a fairly close grid spacing with a surficial bridging layer possibly consisting of compacted stone or lime stabilized soil. The bottom of the Geopiers should extend into stiff clayey soils below a depth of 20 ft having a minimum unconfined compressive strength of 1.0 tsf. This strength value must be checked by a representative of the Geotechnical Engineer during construction. Furthermore, we recommend that the tanks be hydrotested for at least two weeks and drained prior to production filling and pipe connecting. Total and differential tank settlement is estimated not to exceed 3 inches and 1 inch, respectively.

Mr. Aaron Gaul, P.E., Principal Engineer, is the contact at the Geopier Foundation Company. He can be contacted at (816) 421-4334. He can design and price the Geopier system for the project.

Geopiers could be installed prior to placing new grade raising fill or could be installed through new fill ultimately tipping in stiff clayey soils. It should be recognized that stone columns or alternative ground modification systems also may be possible at this site.

4.4      Piles

4.4.1   Pile Overview

The technology provider desires a 100-ton allowable compression capacity. For this load, a medium capacity, 18-inch diameter, 90 ft long auger cast pile was selected since it will most likely be a cost effective pile for this load range. Shorter piles tipping above the sand will have low capacity and will likely not be practical, especially for the heavily loaded silo where the pile spacing will become crowded and possibly less than the minimum 3B (B=diameter) required.

4-4

In addition, since auger cast piles must penetrate into the water bearing sand to exploit the bearing capacity at the pile tip, there is the distinct possibility of a discontinuity occurring at the junction of the clay/sand layer. In fact, past experience on another project with similar geology has indicated that this discontinuity can indeed jeopardize the integrity of the pile shaft. Therefore, the owner will bear more than normal risk if this pile type is selected. Consequently, careful inspection and thorough testing will be required during the installation phase. Unfortunately, the high slenderness ratio (SR) of 60 (SR=D/B where D=pile length) precludes the usefulness of economical low strain testing so pile inspection and testing costs will be substantial.

High capacity, steel H piles driven to bedrock should be considered for silo support. Available steel yield strength has now reached 50 kip/in2 leading to nearly 40 percent recent increase in pile capacity. A 300-ton design load will also lead to a two-thirds decrease in the number of piles. Pile driving records are maintained during installation so each pile is in fact a “self tested” pile, leading to greater certainty with respect to its actual capacity. In addition, H piles are low displacement allowing quicker penetration than a displacement pile also reducing clay heave around the pile. More specific details regarding design of auger cast and H piles are provided in Sections 4.4.2 and 4.4.3 below, respectively.

4.4.2   Auger Cast

The following design parameters are recommended:

·Design compression capacity = 100 tons

·Design uplift capacity = 50 tons

·Design lateral capacity for wide (12 ft) spacing (center to center) = 10 tons

·Design lateral capacity for close (4.5 ft) spacing (center to center) = 4 tons

·Recommended minimum spacing = 4.5 ft

·Pile diameter = 18 in. nominal

·Pile tip elevation = 288 ft

4-5

·28-day grout strength = 4,000 psi

We recommend that piles have a full length No. 10 reinforcement bar. When considering lateral loads, the variations of the shear force, moment and deflection with depth are also shown in Appendix A. The pile should be adequately reinforced to resist these loads. The estimated pile settlement is on the order of 1 to 1½ inches and includes group effects since deep sandy soils below the pile tips will be impacted. Most of the settlement is expected to occur as the loads are applied. Refer to Section 5.3 for pile installation recommendations.

4.4.3   H Pile

The following design parameters are recommended:

·Design compression capacity = 300 tons (see Driven print out in Appendix A)

·Design uplift capacity = 200 tons

·Design lateral capacity for wide (9 ft) spacing (center to center) = 5 tons

·Design lateral capacity for close (3.5 ft) spacing (center to center) = 2.5 tons

·Recommend minimum pile spacing = 3.5 ft

·H pile section = HP 114 x17

·Minimum steel yield strength (fy) = 50 kips/in.2

·Estimated pile tip elevation = 240 ft

The design capacity will be obtained by driving the piles through the overburden soils and then to a sufficient penetration and resistance into shale bedrock. Tip protection is recommended. The actual pile tip depth is expected to vary across the site and will be determined by the Wave Equation analysis. Refer to Section 5.4 for pile installation recommendations.

The estimated pile settlement is 1 inch. A group action reduction factor is not required since the piles will bear on a very strong formation. The majority of pile settlements should occur upon load application.

4-6

4.5      Floor Slab

The floor slab should be supported on a minimum 4-inch thick, granular base course layer, bearing on a lime stabilized subgrade (refer to Section 5.1), or on structural fill overlying the same. In our opinion, the relatively clean, free-draining granular base beneath the floor slab should contain no more than five percent fines, by dry weight, passing a No. 200 U.S. Standard sieve. It is also our opinion that the on-site soils within the anticipated excavation depths do not meet this requirement. We also recommend that a plastic vapor barrier be placed under the floor slab where moisture sensitive floor coverings will be used. The floor slab should be structurally independent of the building columns and walls, and should be liberally jointed. A modulus of subgrade reaction (k30) of 200 pounds per cubic inch (pci) may be used for floor slab design (30- inch plate).

4.6      Below Grade Walls

4.6.1   Lateral Pressure on Below Grade Walls

Below grade walls must be designed to resist lateral earth pressures. The magnitude of lateral earth pressure depends on the type of backfill material, the method of backfill placement and compaction, the drainage characteristics of the wall/backfill system and the degree to which the wall is permitted to yield after placement of the backfill. We assume that below grade walls will be essentially non-yielding and that a relatively free-draining, (non-frost susceptible) granular soil will be placed as backfill against the walls. We recommend that the lateral earth pressure be calculated by assuming that the soil behaves as an equivalent fluid with a unit weight of 50 pounds per cubic foot (pcf). The method of pressure computation recommended above presumes that there will be no hydrostatic pressure due to water buildup against the wall. In addition, lateral pressures due to surface surcharge and traffic loads adjacent to the walls (within a zone defined by a 45 degree slope from the base of the wall) must be considered. A revised equivalent fluid pressure, which includes the effects of these added loads, can be provided upon request.

4.6.2   Groundwater Control

One way to permanently control the groundwater for functional spaces extending below the groundwater table is to use perforated pipes surrounded by a minimum of 6 inches of free- draining granular material and an appropriate filter material (or fabric). These should be placed

4-7

along the base of the foundation wall and under the slab at regular intervals. The pipe invert should be at least 12 inches below the base slab surface and should drain to a storm sewer or a sump pit from which the water can be pumped. In general, this system is most effective in fairly impervious soils at or above the ambient groundwater level. More than normal pumping should be expected at this site where functional spaces extend below the ground surface due to the high water table.

An optional method to handle the groundwater, if permanent drainage is not provided, is to design the walls and base of the functional spaces extending below the groundwater table to resist hydrostatic pressures. Below the water table, we recommend that the lateral earth pressure be calculated by assuming that the soil behaves as an equivalent fluid with a unit weight of 90 pcf. Design concepts to resist hydrostatic uplift include, but are not limited to, increasing the dead load of the foundation, constructing a “lip” on the foundation base and installing soil or rock anchors with uplift capacity. Such foundations should be waterproofed, utilizing volclay panels or equivalent, and water stops, to repel water inflows.

4.7      Pavement

Note: The technology provider has yet to provide design ESAL’s, so no pavement sections are provided yet.

4.7.1   General

Our recommendations are based on the assumption that the paved areas will be constructed on a proof-rolled (or stabilized) subgrade (see Section 5.1), or on structural fill overlying the same. Our recommendations for asphaltic concrete and Portland cement concrete pavement are presented in Sections 4.7.2 and 4.7.3, respectively. These guidelines have been developed from the results of our geotechnical exploration using an assumed medium traffic loading (considerable in-out movement, trucks in designated areas only) and an assumed California Bearing Ratio (CBR) value of four.

4.7.2   Asphaltic Concrete Areas

Serviceable pavements can be achieved by different combinations of materials and thicknesses, varied to provide roughly equivalent strengths. Local practice for existing pavement construction could be reviewed for other blends, or combinations of materials that have been

4-8

found satisfactory, and for applicable minimum standards. For pavements at this site, we provide the following guidelines. Please note that the thicknesses listed below refer to compacted thicknesses.

Light duty pavement areas subjected to only passenger car and light truck loadings:

1.                  inches of combination surface and binder course;

2.                  inches of dense-graded granular base course.

Heavy duty pavement areas subjected to heavy truck loadings, but not truck standing or turnaround areas:

1.                  inches of combination surface and binder course;

2.                  inches of dense-graded granular base course.

When considering the above heavy duty pavement cross section and an assumed CBR value of           , we estimated that an Equivalent Single Axle Load (ESAL) of approximately                      may be used for traffic intensity design for heavy duty pavement areas. If the actual ESAL is higher than this, then increasing the pavement thickness will likely become necessary.

We recommend that the base course consist of a dense-graded, crushed aggregate material, such as No. 53 stone. The gradation of this material is described in the Indiana Department of Transportation (INDOT) specifications. The base course should be compacted to no less than 98 percent of its maximum standard Proctor density, or its equivalent relative density. Further, suitable primer and tack coats should be placed between the base course and between the overlying asphalt layers. In addition, all asphalt material and paving operations should meet applicable specifications of the Asphalt Institute and the INDOT specifications.

Structural fill should be compacted to a minimum of 98 percent of the standard Proctor density (ASTM D-698) in the upper 2 ft and to a minimum of 95 percent of the same below this level. Structural fill in the top 2 ft should also not be frost susceptible.

Where standing water develops either on the pavement surface, or within the base course layer, softening of the subgrade and deterioration of the pavements may occur. Therefore, it is recommended that all project pavements be designed with suitable drainage systems (e.g., underdrains). In addition, if clayey soils are to be used as grade raising fill, we recommend that “finger” drains extend under the base course and discharge into catch basins and/or manholes.

4-9

The procedures we have used to develop our pavement guidelines are consistent with generally accepted engineering practice and are intended to provide a 20-year life span. However, based upon our past experience, we have found that proper construction techniques, quality of drainage, pavement maintenance and actual traffic loads are the major factors in determining pavement life and performance. It is important that experienced technical personnel observe construction activities to check that the pavement layers are constructed as designed.

4.7.3   Portland Cement Concrete Areas

Our experience has indicated that high quality, unreinforced concrete placed on a compacted, minimum 4-inch thick, free-draining base course overlying a stabilized subgrade (see Section 5.1) can provide long-term performance as a rigid pavement system. Satisfactory performance and low maintenance is highly dependent on adequate subgrade drainage and closely spaced joints. A joint pattern not exceeding 15 ft by 15 ft is recommended for unreinforced concrete.

Based on an assumed modulus of subgrade reaction of 200 pci, an assumed 28-day concrete compressive strength of 4,000 psi and ESAL not exceeding                 , a concrete pavement thickness of      inches is recommended for heavy duty pavement. If the actual ESAL is higher than that stated above, then increasing the concrete thickness will likely become necessary.

4.8      Seismic Design

4.8.1   Site Classification

A site classification is required for the calculation of minimum earthquake design forces. The site classification is a function of soil type (i.e., depth of soil and strata types) and depth to bedrock. The follow up borings indicate the bedrock is on the order of 130 ft below the existing grade. Based on the average property descriptions in Table 1613.5.2 of the 2006 IBC along with the soil boring and geophysical results, in our opinion, the soil conditions at this site most closely resemble the site classification D.

4.8.2   Design Spectral Response Acceleration Parameters

The mapped spectral response acceleration coefficients obtained from the USGS zip code earthquake ground hazard website for zip code 47620 are as follows:

0.2 second period: Ss = 0.91g

4-10

1.0 second period: Ss = 0.25g

The site coefficients Fa = 1.14 and Fv = 1.9 were interpolated from the IBC 2006 Tables 1613.5.3(1) and 1613.5.3(2) as a function of the site classification and mapped spectral response acceleration coefficients.

The design spectral response acceleration parameters are as follows:

SDS = 0.69

SD1 = 0.32

Other earthquake resistant design parameters should be applied consistent with the minimum requirements of the Indiana Building Code.

4.9      Foundation Design Parameters

The following engineering parameters are recommended for foundation design:

·Saturated unit weight = 122 lbs/ft3

·Buoyant unit weight = 60 lbs/ft3

·Coefficient of sliding friction of concrete against soil = 0.33

·Coefficient of active earth pressure (drained) = Ka = 0.33

·Coefficient of earth pressure at rest (drained) = Ko = 0.5

·Coefficient of passive earth pressure (drained) = Kp = 3.0

·Coefficient of active earth pressure (undrained) = Ka = 1.0

·Coefficient of earth pressure at rest (undrained) = Ko = 1.0

·Coefficient of passive earth pressure (undrained) = Kp = 1.0

·Cohesion (total stress) = c = 600 lbs/ft2

·Modulus of subgrade reaction for footing up to 10 ft wide = K10’ = 15 pci

·Modulus of subgrade reaction for footing or mat up to 20 ft wide = K20’ = 6 pci

The parameters indicated above are appropriate for the low plasticity clayey soils encountered in the borings.

4-11

4.10    Corrosivity Concerns

Twelve split-spoon samples were composited into three samples representing the upper 10 ft of the soils and tested for corrosivity parameters. The results are shown below.

Boring	Depth (ft)	Chloride  Solid ppm(6)	Sulfate Total Soil ppm(7)	pH Soil	Resistivity (ohms/cm)
B-12	1-10	<100	57.2	7.9	7600
B-21	1-10	<100	59.3	8.2	8440
B-34	1-10	<100	57.2	8.2	7600

Considering a maximum sulfate concentration of 59.3 ppm, the potential degree of sulfate attack is considered negligible7 and sulfate resistant concrete is not required. The soil is not considered corrosive to ductile iron pipe.

4.11    Geophysical Survey

The results of our geophysical investigation is presented in Appendix B (the soil resistivity and thermal conductivity data are shown in Tables 1 and 2, respectively). Based on the results of the shear wave testing, the following low strain shear modulus (Go) can be assumed.

5.0      CONSTRUCTION CONSIDERATIONS

5.1      Site Preparation

Structural areas, plus a minimum 5 ft margin beyond the structure perimeter, should be initially prepared by stripping any vegetation, the upper 6 to 12 inches of topsoil and all other unsuitable materials (including unsuitable debris resulting from the demolition of Southwind Port Road). Thereafter, the lime-stabilization should be implemented. The recommended depth of improvement below foundations, floor slabs and pavements shall be 16 inches.

After the lime-stabilized soils have been allowed to cure for a minimum period of three (3) days, the surface should be proof-rolled to check that the stabilization process was successful. Proof-rolling consists of repeated passes of a loaded, rubber-tired vehicle such as a tandem-axle dump-truck or scraper. The proof-rolling operations should be observed by the soils geo-technician representing the Geotechnical Engineer of Weaver Boos and the proof-rolling vehicle should be loaded as directed by him. Any areas judged by the engineer to rut, pump, or deflect excessively should be undercut and replaced with structural fill (see Section 5.5), or otherwise stabilized (e.g., using additional lime or flyash, geotextile/geogrid reinforcement or bridging stone layers). The above site preparation recommendations should be utilized for proposed pavement and railroad track areas also.

Care should be exercised during the initial grading and construction operations at the site. The combination of excess surface moisture from precipitation ponding on the site and the traffic of heavy equipment, including heavy compaction equipment, may create pumping and general deterioration of the bearing capacities of the shallower soils. Further, the clayey nature of some of the surficial soils combined with potential poor site drainage and high water table make this site particularly susceptible to subgrade deterioration. Thus, grading should be performed during the dry-season, if at all possible. If such problems arise, the operations in the affected areas should be halted pending an evaluation of the conditions by the Geotechnical Engineer.

5.2      Foundation Excavations

Geopiers should be installed where specified. Geopiers shall tip into the stiff clayey soils encountered below an approximate depth of approximately 20 ft and this must be checked by a representative of the Geotechnical Engineer. Prior to placing concrete, all foundation subgrades should be tested with a Static Cone Penetrometer (SCP) to check that an adequate bearing

5-1

capacity exists below the foundation bottom grade. Excavation walls should be sloped (see Section 5.8), shielded or shored in accordance with current OSHA requirements. Any weak soils should be undercut to depths determined by the representative of the Geotechnical Engineer, and the cavity backfilled with granular structural fill, or lean concrete, or the footing can bear at the excavated depth. Where structural fill is installed to backfill foundation undercuts, it should be granular in nature. Further, its limits should extend laterally beyond all edges of the footings at least 6 inches per foot of undercut depth below the foundation bottom grade.

5.3      Auger Cast Pile

Eighteen-inch diameter, auger cast-in-place piles shall be installed with a continuous-flight, hollow-stem auger that is rotated to the tip penetration depth. The formed hole shall be pumped with high-strength grout as the auger is withdrawn. Grout shall be pumped through the auger and ejected at the bottom of the auger head while keeping the bottom of the auger submerged in the mortar during the filling operation. A minimum grout factor of 1.15 is recommended from the ground surface to 80 ft within the clayey soils and 1.3 below (within the sandy soils). The grout factor is obtained by dividing the quantity of grout place in the pile by the theoretical neat volume of the pile. We also recommend a Pile Installation Recorder be utilized for all piles. Reinforcing steel including a full depth No. 10 rebar with an appropriate centering device shall be placed while the mortar is still fluid.

The quality of auger cast piling is very sensitive to the field operations. We therefore recommend that a representative of the Geotechnical Engineer be present during the entire time that the pile installation operation proceeds. In addition, high strain dynamic pile testing of two piles per silo is recommended to verify pile capacity. We recommend that two full-scale field compression load tests be specified. The final loads exerted on the piles during compression tests should reach twice the design load. We recommend that pile installation be in accordance by the “Guidelines, Augered Cast-In-Place (ACIP) Pile Specifications,”(8) prepared with the Deep Foundation Institute and presented in Appendix A.

5.4      Driven Piles

The pile driving hammer should have sufficient energy to drive the piles through the existing overburden soils and then to sufficient penetration and resistance into the shale bedrock. Upon selection of the appropriate hammer size and model, we recommend that a Wave Equation analysis be performed to confirm that the selected hammer, pile section, and soil parameters are matched to provide the specified design capacity. Piles will need to be driven to an ultimate capacity of twice the design load. The Wave Equation analysis will establish the driving criteria, which will control the pile tip elevation in terms of penetration resistance. Several test probe piles (at least one per silo) should be driven around the site to obtain an indication of variability of pile tip elevation.

Several piles should be retapped at least one day after driving (and after all immediate adjacent piles are driven) to check for relaxation and loss of the pile capacity. We recommend that at least one full-scale field compression load test be specified (the actual number will depend upon the driving conditions experienced at the site). After successful completion of the load testing program, the required number of production piles may be ordered from the manufacturer.

We recommend that the Pile Driving Analyzer be utilized to monitor the installation of the test load piles and the test probe piles. The Pile Driving Analyzer will determine the condition of the driving equipment and the efficiency of the drive train. This procedure will reduce problems associated with faulty driving equipment and will reduce the possibility of a pile load test failure. Considering the cost of pile load tests, the use of the analyzer is strongly recommended.

We expect that piles will penetrate several feet into the shale bedrock. Although not encountered in the borings, there may be boulders in the natural soil. Therefore, the construction documents for this portion of the project should include provisions for removing or displacing (i.e., spudding) obstructions, or handling some local drift (e.g., driving sister piles or redesigning pile caps).

The Geotechnical Engineer, or his authorized representative, should be present at all times during installation of foundation piling to observe that the piles are driven in accordance with the specified driving criteria. Installation of piles should be conducted in accordance with applicable codes and general accepted practice.

5.5      Structural Fill

Structural fill, defined as any fill which will support structural loads, should be free of organic material, have a plasticity index less than 25, a maximum particle size of 3 inches, and a maximum dry density in excess of 100 pounds per cubic foot, as determined by the standard Proctor compaction test (ASTM D-698). Granular structural fill should have a fines content not exceeding 5 percent and be free draining and non-frost susceptible. Structural fill should be compacted to at least 95 to 98 percent of its maximum standard Proctor dry density under floor slabs and foundations, respectively.

For the clayey soils (designated as CL), the moisture content should be within -2 to +3 percent of its optimum moisture content. In addition, structural fill in pavement/railroad areas and backfill adjacent to walls should not be frost susceptible. Topsoil containing less than six percent organic material may be reused below roadways provided they are not placed within 2 ft of the roadway base course and some settlement of the roadway surface can be tolerated.

5.6      Fill Placement Control

To achieve the recommended compaction of structural fill, we suggest that the fill be placed and compacted in layers not exceeding 9 inches in loose thickness. To monitor compliance with the recommended density standards, we recommend that in-place density tests be performed at a frequency of at least one test for every 2,500 to 5,000 sq ft of fill area for each lift of compacted fill in structural and paved areas, respectively.

5.7      Groundwater Concerns

At the time of our exploration, the water table appeared to be near or above the expected maximum excavation depth at the site. While no serious dewatering problems are anticipated, some seepage into excavations may be experienced, depending on the seasonal conditions. It is anticipated that most seepage could be handled by conventional dewatering methods such as pumping from sumps. However, where deep excavations extend below water bearing sands for below grade tunnels and pits or any deep undercut areas, a more extensive dewatering effort may become necessary.

5-4

5.8      Slope Stability

Based on our analysis of in-situ soil conditions, excavation slopes should be cut no steeper than 1.0H:1.0V in order to maintain temporary stability of the excavation sides. However, OSHA requirements must be met and may be more restrictive. Our slope value assumes that the dewatering operation has lowered the water table to below the toe of the excavation slope. In addition, we recommend that any surcharge fill or heavy equipment be kept at least 5 ft away from the edge of the excavation. If a 1.0H:1.0V slope value cannot be achieved due to site restrictions at the ground surface, then the excavation sides should be shielded or shored as required.

Permanent slopes should be no steeper than 3.0H:1.0V. A minimum building setback from the top of all slopes of 10 ft is recommended. In pavement areas, a minimum top of slope setback of 5 ft is acceptable. For erosion protection, a protective cover of grass or other vegetation should be established on permanent soil slopes as soon as possible.

If fill is to be compacted on slopes steeper than 8.0H:1.0V (horizontal to vertical), special care must be taken to “tie-in” the compacted fill with the slope. All new fill must be placed and compacted in horizontal lifts and benched into the slope so that a continuous surface is not left between the new fill and the natural soil. The benching can be done with a dozer blade.

Soil and Rock Layering Information

The soil profile is modelled using 7 layers

Layer 1 is soft clay, p-y criteria by Matlock, 1970
Distance from top of pile to top of layer	=	.000	in
Distance from top of pile to bottom of layer	=	132.000	in

Layer 2 is soft clay, p-y criteria by Matlock, 1970
Distance from top of pile to top of layer	=	132.000	in
Distance from top of pile to bottom of layer	=	240.000	in

Layer 3 is stiff clay with water-induced erosion
Distance from top of pile to top of layer	=	240.000	in
Distance from top of pile to bottom of layer	=	324.000	in
p-y subgrade modulus k for top of soil layer	=	.000	lbs/in**3
p-y subgrade modulus k for bottom of layer	=	.000	lbs/in**3

NOTE: Internal default values for p-y subgrade modulus will be computed for the above soil layer.

2

p-y subgrade modulus k for top of soil layer	=	.000	lbs/in**3
p-y subgrade modulus k for bottom of layer	=	.000	lbs/in**3

NOTE: Internal default values for p-y subgrade modulus will be computed for the above soil layer.

Layer 6 is sand, p-y criteria by Reese et al., 1974
Distance from top of pile to top of layer	=	960.000	in
Distance from top of pile to bottom of layer	=	1608.000	in
p-y subgrade modulus k for top of soil layer	=	60.000	lbs/in**3
p-y subgrade modulus k for bottom of layer	=	60.000	lbs/in**3

Layer 7 is weak rock, p-y criteria by Reese, 1997
Distance from top of pile to top of layer	=	1608.000	in
Distance from top of pile to bottom of layer	=	1728.000	in
Initial modulus of rock at top of layer	=	1.0000E+05	lbs/in**2
Initial modulus of rock at bottom of layer	=	1.0000E+05	lbs/in**2

(Depth of lowest layer extends           .00 in below pile tip)

2.0  PRODUCTS

2.1Pile Materials

2.1.1Grout

a.Portland Cement – Portland cement shall conform to current ASTM standards, designation C150.

b.Mineral Admixture – Mineral admixture, if used, shall be flyash or natural pozzolan which can combine with the lime liberated during the process of hydration of Portland cement to form compounds containing cementitious properties. The material shall conform to ASTM C618, Class C or Class F.

c.Fluidifier – Fluidifier shall increase the fluidity of the mixture and act as a water reducing agent and retardant without adversely impacting the design compressive strength of the grout mix.

d.Water – Water shall be potable, fresh, clean, and free of sewage, oil, acid, alkali, salts, organic matter, suspended solids, or other materials that may be detrimental to the grout. Recycled/reclaimed water may be used provided its inclusion and associated temperature does not adversely impact the design compressive strength of the mix.

e.Fine Aggregate – Sand utilized as fine aggregate shall meet the requirements of ASTM C33.

f.Grout Mixes – The grout shall consist of Portland cement, fine aggregate, and water, and may also contain a mineral admixture and approved fluidifier. The components shall be

3

proportioned and mixed to produce a grout capable of maintaining the solids in suspension and being efficiently pumped. These materials shall be proportioned to produce a hardened grout which will achieve the design strength within 28 days. The design 28-day grout strength for this project shall be 3,000 lbs/in2. All materials shall be accurately measured as they are fed to the mixer.

Time of mixing shall be not less than one minute at the site. If agitated continuously, the grout may be held in the mixer or agitator for a period not exceeding two and one-half hours at grout temperatures below 70° F and for a period not exceeding two hours at temperatures not exceeding 100° F. Grout shall not be placed when its temperature falls below 40° F or exceeds 100° F, unless approved procedures for cold or hot weather grouting are followed. Protect grout from physical damage or reduced strength which could be caused by frost, freezing action, or low temperature or from damage during high temperatures in accordance with ACI 305/306. When ambient outdoor temperatures exceed 95° F, a grout temperature of up to 105° F may be allowed, provided the mixing time is reduced to 1 hour and a set retarder is added to the mix.

The grout mix shall be sampled and tested using a set of six (6) two inch cubes for each 50 yd3 of grout placed, or at least one set for each day during which piles are placed. A set of samples shall be taken/tested from each truck of grout delivered during indicator pile installation. Two cubes shall be tested at 7 days, two cubes tested at 28 days, and two cubes held in reserve. Cubes shall be cured and tested in accordance with ASTM C109. Cube specimens shall be restrained from expansion as described in ASTM C942.

g.Adding Water to Grout On-Site – Adding water to the grout on-site is sometimes necessary to provide a consistent grout mixture prior to pumping. The amount of water that may be added to provide both consistent and adequate flow characteristics must not compromise the specified grout strength or, if specified, the water/cement ratio. The total amount of water required to provide adequate flow may exceed the amount listed in the mix design. In this case, the amount of added water should be recorded by the Testing Agency and the Inspector, with samples taken for compression testing.

2.1.2Reinforcing

a.Reinforcing bars shall conform to the requirements of ASTM A615, Grade 60.

b.Reinforcing Bar Fabrication – Reinforcing steel assemblies shall be detailed and fabricated in accordance with the latest Standard Practice for Detailing Reinforced Concrete Structures manual (ACI 315 – latest edition).

3.2Indicator Piles

There are no indicator piles required for this project.

3.3Pile Load Tests

No load testing is required for this project.

3.4Installation Procedure

3.4.1 Tolerance

Piles shall be located as shown on the drawings or as otherwise directed by the Architect/Engineer. Pile centers shall be located to an accuracy of ±3 inches. Vertical piles shall be plumb within two percent. Piles shall be installed to within four percent of the specified incline (or “batter”) as determined by the angle from horizontal.

6

3.4.2 Lengths

The length and drilling criteria for production piles will be determined by the Geotechnical Engineer based on his review of the indicator/probe piles installation, reaction piles and/or test piles, and the pile load tests.

3.4.3 Bottom Plug

The hole in the bottom of the hollow stem auger shall be closed with a suitable plug to prevent soil intrusion into the stem while being advanced into the ground. The plug shall be removed by grout pressure or with the reinforcing bar.

3.4.4 Auger Rate

Advance the auger at a continuous rate to prevent removal of excess soil. Stop advancement after reaching the required embedment into the bearing strata or refusal criteria.

3.4.5 Refusal

Auger refusal is defined as a rate of auger penetration of less than 1 foot per minute of drilling.

3.4.6 Expelling Bottom Plug

At the start of grout pumping, lift the auger 6 to 12 inches from the bottom to facilitate expelling the tip plug. The auger shall then be lowered back down to the previously established tip elevation.

3.4.7 Grout Head/Ratio

Prior to raising the auger, a minimum theoretical initial grout head of 5 ft shall be pumped. Positive rotation of the auger shall be maintained at all times during placement of the grout. The rate of grout injection and auger withdrawal shall be coordinated to maintain:  the minimum grout head at all times, and the total grout volume of at least 125 percent of the theoretical volume for each pile depth increment. After grout is flowing at the ground surface from the auger flighting, the rate of grout injection and auger withdrawal shall be coordinated so that there is at least 100 percent of the theoretical volume for each subsequent depth increment. If grout pumping is interrupted for any reason, or discontinued grout or slurry return at the ground surface is observed, the Pile Contractor shall lower the auger at least 5 ft below the level where the interruption occurred while continuously pumping grout. The grout quantity shall be determined by counting pump strokes and using the predetermined grout volume per pump stroke.

3.4.8 Redrilling

If less than the specified minimum grout factor is placed in any 5-ft increment (at least until the grout head on the auger flighting reaches the ground surface), the auger shall be lowered 5 ft or

7

to the bottom of the pile if that is less, followed by controlled auger withdrawal while maintaining grout injection.

3.4.9 Auger Withdrawal/Rotation

Auger turning and hoisting equipment shall be provided to enable the auger’s continuous rotation in a positive (clockwise) direction while being withdrawn at a steady, continuous rate during grout pumping.

3.4.10 Spoils

The excess spoil that accumulates around the auger due to the drilling process and grout injection shall be promptly cleared away.

3.4.11 Reinforcement

Pile reinforcement shall be installed immediately upon completion of the grouting operation, and before the grout reaches its initial set; single bars may be installed through the center of the hollow stem of augers so fitted prior to grouting. The reinforcement shall be free of soil, auger spoil, or other deleterious materials prior to insertion into the grouted shafts. The reinforcement shall fall freely under its own weight to the specified level within the shaft; vibration or pushing of the cage with equipment shall not be undertaken unless permitted by the Architect/Engineer.

3.4.12 Adjacent Piles

Adjacent piles with six pile diameters, center to center, shall not be installed within 12 hours of each other.

3.5Obstructions

If non-augerable material is encountered above the desired tip elevation, such as cobbles, boulders, rock, metal, timbers or debris which causes auger refusal (as defined in Paragraph 3.4.5, herein), the pile shall be completed to the depth of the non-augerable material in accordance with these specifications. The length of such short piles shall be included in the total linear feet of pile for payment. If required by the Architect/Engineer, additional adjacent piles shall be placed and the length of these additional piles shall also be included in the total linear feet of piles for payment.

3.6Pile Completion

a.The level of grout in completed piles shall be periodically inspected for settlement. Should grout settlement occur, the pile may be filled with grout provided any deleterious materials that may have accumulated on top of the settling grout are completely removed. The level of grout should not be permitted to settle below the groundwater

8

level prior to initial set. Special attention should be paid to inspecting the level of grout in a completed pile while installing an adjacent pile.

b.Where the pile cutoff is near or above the surrounding ground surface or above the bottom of the excavation, sleeves or casing of the proper diameter at least 18 inches in length shall be placed around the pile tops. Removal of fluid grout by dipping or any other means in a completed pile prior to the grout attaining its initial set shall only be performed if approved by the Geotechnical Engineer and if witnessed by the Inspector.

c.Cut off the tops of piles, square with pile axis and at the elevations indicated by removing fresh grout from the top of the pile or by cutting off hardened grout down to final cutoff point at any time after initial set has occurred.

3.7Post-Construction Testing

Completed piles or questionable piles may be specified for post-construction non-destructive testing (NDT).

3.8Pile Acceptance

The Architect/Engineer will evaluate the pile installation data obtained by the Inspector, grout sampling/testing data provided by the Testing Agency, and any supplemental information provided by the Geotechnical Engineer and determine the acceptability of the completed piles. The Architect/Engineer will notify the Pile Contractor if a pile is not in conformance with the specifications.

4.0  PAYMENT

The base bid shall be for the total linear feet of piles called for on the drawings and in the specifications.  Payment for increase or decrease in actual total pile footage installed and increase or decrease in the number of piles installed shall be in accordance with the respective unit prices in the Contract.  Payment for changes in the number of pile load tests shall be in accordance with the respective unit prices in the Contract.

Re:Results of a Geophysical Investigation
Proposed Mount Vernon Dry Mill Ethanol Plant
Mount Vernon, IN

Dear Mr. Coats:

Weaver Boos Consultants, LLC (WBC) has prepared the following report to document the procedures and findings from geophysical surveys performed at the proposed Mount Vernon Dry Mill Ethanol Plant in Mount Vernon, Indiana. This work was completed in general accordance with our Proposal No. P70129 dated April 9, 2007, and was authorized by you on April 16, 2007. The scope of work included ten electrical resistivity soundings, six test pits and thermal resistivity tests, and one seismic survey to evaluate shear wave velocities through the Multi-channel Analysis of Surface Wave (MASW) method.  Shear wave velocities were used to calculate the shear moduli presented in our Final Geotechnical Exploration Report. The results of our findings are presented below.

SOIL RESISTIVITY SURVEYING

Soil resistivity measurements were recorded at ten sounding locations as shown in Figure 1. Measurements were recorded using a four-electrode Wenner array in general accordance with ASTM Standard G57-95a (2001) “Standard Test Method for Field Measurement of Soil Resistvity Using the Wenner Four Electrode Method” and IEEE No. 442-1981 “IEEE Guide for Measuring Earth Resistivity, Ground Impedance, and Earth Surface Potentials of a Ground System”. A STING R1 Resistivity Meter from Advanced Geosciences, Inc. was used to record the data. Apparent resistivity values were calculated at a-spacings of 3, 6, 9, 12, and 15 ft as

designated by Bibb & Associates. A minimum of three measurements were recorded at each a-spacing; the value with lowest percent error is presented in Table 1. Electrodes were expanded in the direction of the double-arrow shown in Figure 1.

THERMAL RESISTIVITY TESTING

Soil thermal resistivity tests were performed in general accordance with ANSI/IEEE Standard 442-1996 “Guide to Soil Resistivity Measurements”. WBC used a KD2 Pro Portable Thermal Properties Sensor to measure thermal resistivity in six test pits at the locations shown in Figure 1. This instrument is in compliance with the ANSI/IEEE standard and uses a single-needle sensor to measure the thermal resistivity or conductivity of the medium. A 10 cm needle was used for all measurements to conform to ASTM and IEEE standards. Two measurements were recorded at a depth of 5 ft below ground surface approximately 15 minutes apart to allow the needle to equilibrate between readings. The needle sensor was inserted in a Styrofoam block between measurements. Thermal conductivity (W/moC), thermal resistivity (cmoC/W) and volumetric specific heat (C) results are tabulated in Table 2.

MULTI-CHANNEL ANALYSIS OF SURFACE WAVES (MASW)

Active and passive surface wave techniques were used to determine shear wave velocity profiles (Vs) along one seismic spread near the north end of the site (see Figure 1). Unlike former methods which utilized a source and two receivers in three boreholes, testing with the MASW method is performed at the surface, and relies on the dispersive character of the Rayleigh waves. The “active” portion of data collection is similar to that of seismic refraction. Surface waves are generated by a dynamic source, in this case a sledge hammer and steel plate offset 20 ft from each end of the seismic line. The various wavelengths of the surface waves were monitored by a multi-channel seismograph and 24 receivers (4.5 Hz geophones) installed in the ground at 5 ft intervals. Each record was recorded using a 1-second record with ½ millisecond sampling interval. The effective exploration depth of the active test is estimated at one-half the spread length, or approximately 50 to 60 ft below ground surface (bgs).

The “passive” portion of the data collection essentially measures the ambient noise, i.e. surface waves generated from passing traffic, wind, etc. Geophone spacing was increased to 10 ft, and record length was increased to 32 seconds with a 2-millisecond sampling interval. The dispersion curve for the passive test is defined as the lower envelope of the Rayleigh wave

energy, which represents greater depths. By integrating the active and passive tests, the method is capable of exploring depths over 100 ft bgs.

Rayleigh wave velocity is determined by the material properties (primarily shear wave velocity) of the subsurface. The Rayleigh wave dispersion curve is obtained by a wavefield transformation of the seismic field record, which effectively isolates the surface wave energy from the body waves. The surface wave dispersion curve is then modeled or inverted to obtain a shear wave velocity profile. For this investigation, the program SurfSeis v.2.05 by the Kansas Geological Survey was used to analyze the combined active and passive dataset. However, wild variations observed in the near surface data were not considered realistic, and as a result the data were also analyzed in the program SeisImager.

The dispersion curves and shear wave velocity profiles created in both programs are presented in Figures 2 (SurfSeis) and 3 (SeisImager). The general trends and layer boundaries of the interpreted results are generally consistent between the two programs, with several important differences. For example, the shallow data (0-20 ft ± bgs) on the SeisImager inversion (see Figure 3) are more realistic and are therefore considered more reliable that those from SurfSeis. The dispersion curve from SeisImager also permitted slightly deeper interpretation, and appears to show the bedrock interface at approximately 121 ft bgs. Although the trends on the two profiles are very similar, the magnitude of interpreted shear wave velocities appears to be greater on the SurfSeis inversion. Despite these differences, average shear wave velocities on both profiles is greater than 600 ft/second. Individual shear velocities for each interval are included on the SurfSeis inversion (see Figure 2). Average shear wave velocities were used to calculate the shear moduli, the results of which are presented in our Final Geotechnical Exploration Report.

EXHIBIT E
MECHANICAL COMPLETION, COMMISSIONING, STARTUP

Definitions:

Mechanical Completion:  The completion of construction activities essential to the safe and proper operation of the Plant in accordance with the requirements of the Contract, as more fully listed below to the extent necessary to permit:

(i)safe and sound start-up and operation of the Plant as a fully integrated system; and

(ii)successful completion and conduct of the commissioning tests.

but excluding correction of minor non-operational matters such as painting, landscaping and nonessential insulation. Nonessential insulation shall not include any insulation needed for personnel safety, any insulation that materially and negatively impacts the process or any outdoor process piping insulation required for freeze protection.

Irrespective of the following, Mechanical Completion shall be deemed to have occurred in the event feedstock has been introduced into the process and ethanol has been produced.

Commissioning:  The checking, testing and preparation of the Plant for operation, functional control loop checking, interlock testing, system purging and utility system startups, as more fully listed below.  In general, the tasks required for taking the Plant from Mechanical Completion and making it ready for start-up.

Ready for Startup:  When the activities listed for Mechanical Completion and Commissioning have occurred and the Plant is ready to mill corn at the hammer mills.  At that time, KIEWIT will notify OWNER that the Plant is Ready for Startup.  All paved roads must be completed before the Plant is ready for Startup.

Startup:  Startup begins with the initial feed of raw material to the Plant, filling of Equipment with operating material, startup and operation of individual process stages, adjustment and optimization of operating conditions, optimization of control loops, verification of startup, shutdown and partial load operations.  Utility system startups (unless integrated with the processing portions of the Plant) are a part of the Commissioning Phase.

Substantial Completion:  As defined below.

These events may not occur at the same point in time for all parts of the Plant.  Utility systems needed for operation of the rest of the Plant may reach Mechanical Completion, Commissioning and Startup before the main process parts of the Plant.  Some processing areas of the Plant or sub-systems of operating areas may reach Mechanical Completion and be Commissioned and Started up before other parts of the Plant, for example, grain receiving and storage may be completed and into operation, i.e., filled with grain, prior to other parts of the Plant.  Mechanical Completion, Commissioning and

1

PROCESS SAFETY MANAGEMENT
CONTRACTORS

A.Policy

Aventine Renewable Energy, Inc. is committed to the prevention of accidents and improving quality and productivity related to Contractor work by providing a safe workplace that protects Aventine and Contractor employees, the environment and the general public.

Aventine shall promote an attitude of partnership, cooperation, and communication with Contractors to enhance workplace safety. Personal safety is a fundamental responsibility of both Aventine and Contractor employees.

Aventine shall maintain the independent contractor status of its Contractors and their Subcontractors. Aventine shall not dictate the manner and means by which the Contractor performs its work, except where specified in the written contract; and, whenever unsafe acts/unsafe conditions pose an immediate threat to the safety or health of personnel; and/or potential damage to Aventine property.

B.Purpose

To establish a policy and procedure for providing Aventine employees with guidance in developing site-specific rules and practices to improve the safety and health performance of contractors who perform work at Aventine.

To ensure that all Contractor personnel are informed of the known potential fire, explosion, toxic release hazards, and other serious safety hazards related to their work or the process.

To ensure that all Contractor personnel are aware of all applicable Aventine safety rules and procedures pertaining to their work site, including the facility’s emergency procedures.

This procedure applies to Aventine employees responsible for Contractor selection, training, inspections and assessments, and for Contractor work involving new construction projects, major renovation, and repair/maintenance activities.

* Note: Repair/maintenance activities and incidental contractor work that do not compromise the safety of personnel, facilities, and processes are excluded. (E.g., janitorial and delivery services, etc.)

1

C.Approach

Contract employees must perform their work safely. Considering that Contractors often perform very specialized and potentially hazardous tasks, such as confined space entry activities and non-routine repair activities; their work must be controlled while they are on or near a process covered by PSM. A permit system or work authorization system for these types of activities are required for all affected employees. The use of a work authorization system keeps an employer informed of contract employee activities. A well-run and well-maintained process, where employee safety is fully recognized benefits all of those who work in the facility whether they are employees of the employer or the contractor.

D.Responsibilities

When selecting a contractor, the employer must obtain and evaluate information regarding the contract employer’s safety performance and programs. The employer also must inform contract employers of the known potential fire, explosion, or toxic release hazards related to the contractor’s work and the process. The employers must explain to contract employers the applicable provisions of the emergency action plan; develop and implement safe work practices to control the presence, entrance, and exit of contract employers and contract employees in covered process areas; evaluate periodically the performance of contract employers in fulfilling their obligations; and maintain a contract employee injury and illness log related to the contractor’s work in the process areas.

E.Program Elements

Proper safety procedures and equipment must be utilized and maintained at all times for protection of all personnel and facilities.

·Before beginning work, the Contractor or his qualified supervisors shall inspect the premises, location of work area, and examine all safety rules and instructions to determine the nature and extent of difficulties and hazards.

·Contractor shall promptly report in writing, all accidents in connection with the work. Full details and statements of witnesses shall be included in the reports on any accident that has resulted in injury, property damage, or death.

·Aventine reserves the right to suspend any Contractor where life or Company property is imperiled. The Contractor shall suspend work when notified by the Company that any personnel or equipment are exposed to unreasonable hazards.
