If a Scope Change Order results in an increase or decrease in the Contract Price, the revised Contract Price (reflecting the increase or decrease as a result of the Scope Change Order) shall exclude all applicable taxes. Client shall reimburse Contractor for all applicable taxes paid by Contractor in accordance with the provisions of this Section 4.2.

4.3 Payment Schedule. Client shall make payments to Contractor in installments, as set forth below.

4.3.1 Appendix B-1 sets forth the Preliminary Schedule of Values for the Project. Within thirty (30) days after the date hereof, Contractor shall submit for Client’s review and approval a detailed schedule of values (“Schedule of Values”) (which shall be consistent with the Preliminary Schedule of Values). Payments shall be made pursuant to the provisions set forth below.

(a) On or before the tenth (10^th) day of each month following the month in which the Commencement Date occurs, Contractor shall deliver to Client a Progress Invoice, for the period ended on the last day of the previous month, together with supporting documentation (including the relevant Monthly Progress Report and the value of Work completed since the prior invoice, based on the Schedule of Values) consistent with Contractor’s invoicing practices and waivers and releases of Liens in substantially the forms set forth in Appendix G-1, Appendix G-2 and Appendix G-3, duly executed and acknowledged by Contractor and each Subcontractor that has provided equipment or services to the Contractor having a value in excess of $100,000 through the date of the invoice. Client shall pay Contractor, or cause Contractor to be paid by Financing Parties, ninety-five percent (95%) of the approved amount due on or before the date which is twenty (20) days following the date Client receives such Progress Invoice (each such payment, a “Progress Payment”). The five percent (5%) of approved amounts not paid to Contractor is referred to as “Retainage”. Notwithstanding the foregoing in this Section 4.3.1, with respect to (i) the payment made to Contractor on the date that the Notice to Proceed is given and (ii) each payment made with respect to the first five Progress Invoices, the Retainage shall be five percent (5%) plus an amount equal to (1/6) x (.05) x the total of Advance Payments made by Client. The accumulated Retainage less one two hundred percent (200%) of the value of the Punch List, less the reasonably estimated value of any Contractor Liens or other Liens or charges that have been filed against all or any part of the Facility or the Facility Site in connection with this Agreement and less liquidated damages payable by Contractor pursuant to Articles 7 and potentially payable by Contractor pursuant to Article 8, if any, shall be paid to Contractor upon achievement of Substantial Completion. Payment Progress Payments shall be made by wire transfer to an account or accounts designated in the Progress applicable Progress Invoice. Late payments will bear interest at the Wall Street Journal prime rate plus five percent (5%).

(b) If there is any dispute about any amount invoiced by Contractor, the amount not in dispute shall be promptly paid as described above, and any disputed amount which is ultimately determined to have been due shall be paid with interest from

the date of withholding to the date of payment as set forth in Section 24.1. Client will provide a notice to Contractor within ten (10) days after receipt of Contractor’s invoice concerning any invoiced amounts disputed by Client.

(c) In lieu of all or a portion of any Retainage to be withheld by Client under this Section 4.3.1, Contractor may provide to Client, at any time, one or more irrevocable letters of credit for Client’s benefit (which shall be transferable to the Financing Parties) in an aggregate stated amount of up to the full amount of Retainage withheld to date. Such letter(s) of credit shall secure Contractor’s obligations under this Agreement and shall be drawable from time to time in whole or in part (for an amount necessary to satisfy Contractor’s obligations up to the amount of Retainage required from Contractor at the time of such draw) on demand by Client upon any failure of Contractor to complete Punch List items, or pay liquidated damages when due in accordance with this Agreement, or otherwise comply with its material obligations hereunder. The issuer and terms of the letter(s) of credit shall be reasonably acceptable to Client and Financing Parties, and the letter(s) of credit shall continue in effect until thirty (30) days following Project Completion. Within ten (10) days following the delivery to Client of any such letter(s) of credit, Client shall release and pay to Contractor Retainage (to the extent then withheld from Progress Payments theretofore made by Client), and thereafter, unless the letter(s) of credit is terminated or has expired, Client shall not withhold Retainage from future payments to Contractor until such time as the total Retainage that would otherwise be withheld by Client is equal to or in excess of the aggregate amount available to be drawn under such letter(s) of credit.

4.3.2 Upon Project Completion, pursuant to Section 6.7, Contractor shall submit a statement summarizing and reconciling all previous invoices, payments and Change Orders. Except as provided elsewhere in this Agreement, within twenty-five (25) days of the receipt of such statement, Client shall pay Contractor, or cause Contractor to be paid by Financing Parties, all remaining amounts due.

4.4.1 Upon termination of all or part of the Work pursuant to Section 15.1 or 15.2 (and subject to Section 4.4.2), Contractor shall be entitled, subject to the provisions of Section 4.4.3, to a payment (the “Termination Payment”) consisting of the total of (i) Contractor’s costs incurred in connection with performance by Contractor of Work prior to the date of termination which have not been previously paid by Client, (ii) all documented costs reasonably incurred by Contractor to implement the termination, preserving or protecting the Work, including demobilization and travel costs, (iii) Subcontractors’ termination charges, if any, reasonably incurred as a direct result of the termination and which cannot be reasonably avoided and (iv) a fee equal to fifteen percent (15%) of the total amounts described in (i), (ii) and (iii) above.

4.4.2 Notwithstanding Section 4.4.1, in the event that Client terminates the Work prior to the date that Notice to Proceed has been given by Client, Contractor shall be entitled to retain payments for Work rendered prior to such termination, based on the rates set forth in Exhibits C to the Limited Notice to Proceed. Contractor shall return or refund the portion of payments made to Contractor which are in excess of the value of the Work provided prior to termination, less any cancellation charges owed by Contractor to Subcontractors, vendors, and equipment suppliers. Contractor shall take reasonable steps to cancel all existing subcontracts and purchase orders upon any notice of termination and to mitigate the costs associated with such cancellation. In no event upon termination under this Section 4.4.2, shall Contractor be entitled to additional payment from Client. Client shall be entitled to possession and ownership of any Work product produced by Contractor.

4.4.3 Payment of the Termination Payment. Client shall pay the Termination Payment to Contractor within thirty (30) days of receipt by Client of the items and documentation required under Section 4.4.1 or Section 4.4.2.

(a) Contractor shall provide written notice to Client that the requirements of Mechanical Completion have been satisfactorily achieved, (the “Notice of Mechanical Completion”).

(b) Within five (5) business days following receipt by Client of such Notice of Mechanical Completion, Client shall notify Contractor in writing whether Contractor has satisfactorily achieved Mechanical Completion.

(c) If Contractor has not satisfactorily achieved the requirements for Mechanical Completion, Client shall specify in such notice to Contractor, in reasonable detail, the reasons for Client’s determination that the requirements for Mechanical Completion have not been satisfactorily achieved. Contractor shall promptly act to correct such deficiencies so as to achieve Mechanical Completion in accordance with the Project Schedule.

(d) If Client fails to respond to Contractor’s Notice of Mechanical Completion within the five (5) day period set forth in Section 6.1(b) above, Mechanical Completion shall be deemed to have been achieved on the date Client received such Notice from Contractor.

(e) Following any such remedial action, Contractor shall deliver to Client a second Notice of Mechanical Completion and the provisions of this Section 6.1 shall apply with respect to such new notice in the same manner as they applied to the original notice.

The foregoing procedure shall be repeated until Mechanical Completion has been satisfactorily achieved as indicated in a written notice from Client.

6.1.1 Punch List. Upon achievement of Mechanical Completion of the Facility, Contractor shall provide the Punch List to Client together with a value for and a schedule for completion of each Punch List item. Client shall, within ten (10) business days of receipt of the Punch List, notify Contractor that it accepts such Punch List or shall otherwise state its reasons for disagreement therewith in reasonable detail; provided, however, that acceptance or rejection thereof shall not relieve Contractor of its liability to complete or correct the Punch List items. Upon Contractor’s completion or correction of each item on the Punch List, Client shall indicate acceptance of such item and make payment to Contractor of the funds held with respect to such item.

6.2 Startup. Contractor shall pursue Startup of the Facility in accordance with Good Practices. Contractor shall, in consultation with Client and its operating personnel, direct the operation of the Facility during Startup in a manner consistent with Good Practices and all Applicable Laws.

Contractor shall give Client at least seven (7) days’ (but not more than 10 days’) prior written notice of the date on which Contractor intends to commence the initial Performance Test. Contractor shall perform and re-perform additional Performance Tests until Substantial Completion is successfully achieved. After Provisional Acceptance is achieved, subject to Section 6.3.1(b) below and Section 6.5.4, Contractor may, without any increase to the Contract Price, take Corrective Action to the Facility and re-perform the Performance Tests for a period of up to one hundred eighty (180) days in order to improve the performance results up to the Performance Guarantees and to reduce Contractor’s liability for amounts payable as Performance Guarantee Payments. An extension of such period may be granted at the Client’s discretion if Client believes that the Contractor is making a good faith effort and demonstrating tangible progress toward achieving the Performance Guarantees. Contractor shall keep the Client’s Representative continuously apprised of the specific schedule, and changes therein, for the commencement and re-performance of

Performance Tests. Contractor, at its reasonable discretion, may abort any attempted Performance Test.

(b) “Corrective Action” shall mean materials, tasks and Work necessary or appropriate to make the Facility meet each Performance Guarantee and to achieve Project Completion, including providing assistance to, and coordinating efforts of items within Client’s Scope be the reason, in whole or in part, for not meeting any Performance Guarantee. Corrective Action Work performed by Contractor to the extent required by underperformance of items within Client’s Scope shall be subject to Scope Change pursuant to Article 12.

6.3.2 Disposition of Output. At all times when Contractor desires to conduct Startup, testing, Performance Tests or other operations of the Project or Project systems in furtherance of Performance Tests or repair and maintenance, Client shall, at no expense to Contractor, arrange for the disposition of the Facility’s output of ethanol, wet cake, DDGS and all other outputs in such manner that does not hinder or disrupt Contractor’s Work.

Following any action taken by Contractor after notice from Client that Contractor failed to successfully achieve Provisional Acceptance, Contractor shall deliver to Client a new Notice of Provisional Acceptance and the provisions of this Section 6.5 shall apply with respect to the new notice in the same manner as they applied to the original notice. Such procedure shall be repeated as necessary until Provisional Acceptance has been successfully achieved.

6.5.4 Risk of Loss. Contractor, at all times prior to Provisional Acceptance, shall bear the risk of physical loss or damage to the Facility, including all materials, equipment and supplies (including temporary materials, equipment and supplies), regardless of whether Client has title thereto.

7.2.3 Payments Reasonable. Client and Contractor hereby acknowledge and agree that the terms, conditions and amounts fixed pursuant to Section 7.2 for Late Completion Payments are reasonable, considering the reduction in value of the Project to Client and the actual costs that Client will incur and other losses that Client will sustain in the event of Contractor’s failure to achieve Provisional Acceptance by the Guaranteed Completion Dates. The amounts of these payments are agreed upon and fixed by the Parties as liquidated damages because of the difficulty of ascertaining the exact amount of reduction in value, costs and other losses that will be actually incurred by Client in such event, and the Parties hereby agree that the payment amounts specified herein are not penalties and shall be applicable regardless of the amount of such reduction in value, costs and other losses actually incurred by Client. The payment of any Late Completion Payments shall not affect Client’s rights to (i) terminate the Agreement pursuant to Article 15 or (ii) receive liquidated damages pursuant to Article 8.

7.2.4 Payment. Contractor shall pay the amounts required under this Section 7.2 on or before the fifth (5th) day of each month for amounts due with respect to delays that occurred during the preceding calendar month.

ARTICLE 11

Force Majeure

11.1 Force Majeure Event. As used in this Agreement, a “Force Majeure Event” shall mean any act or event that prevents the affected Party from performing its obligations under this Agreement if such act or event is beyond the reasonable control of and not the fault of the affected Party. A Force Majeure Event shall include, but not be limited to, the following events: war, lightning, earthquake, fire, volcanic eruption, landslide, typhoon, hurricane, flood, tornado, other unusually severe weather, explosion, strikes or labor disputes (but expressly excluding any strikes or labor disputes involving only employees or other direct labor of Contractor or its Subcontractors at the Facility Site), civil disturbance, act of God or the public enemy, or action

of a court or public authority (provided that if a claim of Force Majeure event asserts an unreasonable delay or inaction of a public authority, such delay, action or inaction shall only be a Force Majeure event, if proper and timely application therefore was made, taking into account all facts and circumstances after due investigation into the time required for such requested action, payments of all necessary fees and charges was made, and diligent and customary pursuit of the application was made). The following events are explicitly excluded from Force Majeure Events and are solely the responsibility of the affected Party: (a) late delivery of equipment or materials (unless caused by a Force Majeure Event), (b) economic hardship, or (c) nonperformance or delay by Subcontractors (unless caused by a Force Majeure Event).

11.2 Excused Performance. Except for payment obligations accruing in accordance with this Agreement for Work that is not affected by a Force Majeure Event, if either Party is rendered wholly or partially unable to perform its obligations under the Agreement because of a Force Majeure Event, that Party will be excused from whatever performance is affected by the Force Majeure Event to the extent so affected; provided that:

(a) The affected Party, within ten (10) business days after becoming aware of the occurrence of a Force Majeure Event, gives the other Party written notice describing the particulars of the occurrence, including an estimation of its expected duration and probable impact on the performance of such Party’s obligations, and thereafter continues to furnish timely regular reports with respect thereto during the continuation of the Force Majeure Event and the effects thereof;

(b) The suspension of performance shall be of no greater scope and of no longer duration than is reasonably required by the Force Majeure Event;

(c) No liability of either Party for an event which arose before the occurrence of the Force Majeure Event shall be excused as a result of the occurrence, except that the obligation for any on-going Late Completion Payments shall cease during the delay caused by the Force Majeure Event; and

(d) The affected Party shall exercise all reasonable efforts to mitigate or limit damages to the other Party; provided, however, notwithstanding anything in this Agreement to the contrary, the affected Party shall not be obligated to accelerate its Work or otherwise incur costs which would not normally be incurred in performance of the Work in order to overcome any delay due to a Force Majeure Event, unless such Party is compensated for the costs resulting from such acceleration in accordance with Article 12.

The Parties shall execute a Change Order pursuant to Article 12 to equitably adjust the Contract Price and Project Schedule as a result of each Force Majeure Event.

ARTICLE 12

Scope Changes

12.1 Scope Changes. Client, without invalidating this Agreement, may order Scope Changes to the Work, where one or more of the Contract Price, the Guaranteed Completion Dates, the Payment Schedule, the Project Schedule or the Project Guarantees and other such parts of this Agreement as may be affected by such Scope Change shall be adjusted as necessary. If Client decides not to issue a Scope Change after having requested one, unless such Scope Change Request is issued in response to a Contractor Scope Change Order Notice as set forth in Section 12.2.2 below, Contractor shall be entitled to reasonable compensation for providing any engineering services in responding to Client’s Scope Change Request. Such reasonable compensation shall be determined in accordance with Appendix K. All Scope Changes shall be authorized by a Scope Change Order and only the Client or Client’s Representative may issue Scope Change Orders.

12.2 Procedure for Scope Changes.

12.2.1 As soon as reasonably possible, but in no event later than fifteen (15) days after Contractor becomes aware of any circumstances which Contractor has reason to believe may constitute a Scope Change, Contractor shall issue to Client a Scope Change Order Notice at Contractor’s expense. All Scope Change Order Notices shall include preliminary documentation sufficient to enable Client to determine (i) the factors necessitating the possibility of a Scope Change; (ii) the impact which the Scope Change is likely to have on the Contract Price; (iii) the impact which the Scope Change is likely to have on scheduling and the Guaranteed Completion Dates; and (iv) any other adjustments to this Agreement which Contractor believes should be made as a result of the Scope Change.

12.2.2 If Client desires to make a Scope Change in response to a Scope Change Order Notice or otherwise, it shall submit a Scope Change Order Request to Contractor. Contractor shall promptly review the Scope Change Order Request and notify Client promptly in writing of the options for implementing the proposed Scope Change (including, if possible, any option that does not involve an extension of time) and the effect, if any, each such option would have on the Contract Price, the Guaranteed Completion Dates, the Payment Schedule, the Project Schedule, or the Project Guarantees, or any other such part of this Agreement as may be affected. The preparation and provision of information to Client in response to Scope Change Order Request shall be at Contractor’s expense if such Scope Change Order Request is issued in response to a Scope Change Order Notice issued by Contractor.

12.2.3 If a Scope Change is in order, Client shall issue a Scope Change Order, in which event the Contractor’s response to a Scope Change Order Request pursuant to Section 12.2.2 shall be binding on Contractor. In the event Client disagrees with Contractor’s statement of the effect of such Scope Change on any one or more of the Contract Price, the Guaranteed Completion Dates, the Payment Schedule, the Project Schedule, the Project

Guarantees, or any other such part of this Agreement as may be affected, Client may proceed to issue the Scope Change Order in accordance with Section 12.7.

12.2.4 Client shall issue a Scope Change Order for each Scope Change.

12.3 Scope Changes Due to Contractor Error. Except as provided in Sections 12.4, 12.5, 12.6 or 12.7, no Scope Change Order shall be issued and no adjustment of any one or more of the Contract Price, the Guaranteed Completion Dates, the Payment Schedule, the Project Schedule or the Project Guarantees shall be made in connection with any delay, failure of performance, correction of errors, omissions, deficiencies or improper or defective Work, machinery, equipment, materials, systems, supplies or other items on the part of Contractor or any Subcontractor in the performance of the Work or provisions of, or delay in provisions of machinery, equipment, materials, systems, supplies or other items by Contractor or any Subcontractor, or any failure of Contractor or any Subcontractor to comply with the Agreement.

12.3.1 To the extent any delay or failure of performance was concurrently caused by Client and Contractor, Contractor shall be entitled to an adjustment of the Contract Price, the Project Schedule and Guaranteed Completion Dates for only that portion of the critical path delay that was due to Client, provided that Contractor submits a proper Scope Change Order Notice in accordance with Section 12.2.1.

12.4 Scope Changes Due to Changes in Law. Any changes in Applicable Laws enacted after the Effective Date of this Agreement which Contractor believes may constitute a Scope Change, shall entitle Contractor to request equitable adjustments to the Contract Price, Project Schedule and other obligations under this Agreement by issuance of a Scope Change under Section 12.2.

12.5 Effect of Force Majeure Event. Subject to the final sentence of Section 11.2, in the event and to the extent that a Force Majeure Event affects Contractor’s ability to meet the Guaranteed Completion Dates, the Payment Schedule or the Project Schedule, an equitable adjustment in one or more of the Guaranteed Completion Dates, the Payment Schedule and the Project Schedule shall be made. Subject to the final sentence of Section 11.2, in the extent a Force Majeure Event adversely impacts Contractor’s cost of performance of the Work, such event shall be treated as a Scope Change and an equitable adjustment in one or more of the Guaranteed Completion Dates, the Payment Schedule, the Project Schedule and the Contract Price shall be made. To the extent Contractor cannot reasonably redeploy labor or equipment, reasonable standby and mobilization/remobilization costs incurred by Contractor resulting from any such delay shall be reimbursed to Contractor monthly as such costs are incurred.

12.9 Scope Change Order Constitutes Complete Relief. Except for aggregate impacts which are either unknown, or despite the exercise of reasonable diligence would not be known at the time of execution of a Scope Change Order, any Scope Change Order agreed to between the Parties shall constitute full compensation to Contractor for all claims for cost for direct, indirect, labor, temporary construction failures, job site, or home office overhead, stacking of trades, inefficiencies, impacts or any other cost of any kind or nature; and in the event the Scope Change Order adjusts the Guaranteed Completion Dates, the executed Scope Change Order constitutes complete relief to Contractor for schedule impacts for all events giving rise to the Scope Change Order.

Client may for its convenience and without cause terminate all remaining Work at any time by delivering notice to Contractor specifying the effective date of termination. Immediately upon receipt of such notice, Contractor shall stop performance of the Work, immediately order and commence preservation or protection of the Work as instructed and demobilization with regard to the Work, assign all title to all Work not already owned, all Subcontracts as designated by Client and all applicable Governmental Approvals to Client, terminate all other Subcontracts, and remove from the Facility Site all tools, Contractor’s Equipment and rubbish.

In the event of such a termination by Contractor, Client shall pay to Contractor such amount as is required pursuant to Section 4.4.

Notwithstanding the foregoing, Client may terminate the Agreement upon thirty (30) days’ notice to Contractor if Contractor disregards any material provision of any Applicable Law, provided any such failure is not remedied within such thirty (30) day period.

(c) In the event that a Parent Guarantee is provided in accordance with Section 4.5 and (i) Guarantor takes any action that results in the termination of the Parent Guarantee prior to the date on which Contractor has no further obligations to Client under the Agreement or (ii) Guarantor fails to perform any duty, obligation, warranty, or responsibility imposed upon Guarantor under the Parent Guarantee or this Agreement, Client may at its option, without prejudice to any other right or remedy Client may have under the Agreement, at any time terminate this Agreement immediately upon written notice to Contractor.

15.4 Consequences of Termination. Upon any termination pursuant to Section 15.3, Client may at its option elect to (a) take possession of the Project and any or all Work, materials or equipment located at the Facility Site and intended to be incorporated into the Facility and all drawings, design and related documents (wherever located), and (b) subject to the third sentence of this Section 15.4, succeed automatically, without the necessity of any further action by Contractor, to the interests of Contractor in any or all Subcontracts entered into by Contractor with respect to the Project provided Contractor shall retain all of its rights against such Subcontractors for any claims of Client for which Contractor is responsible, and Client shall be required to compensate such Subcontractors only for compensation becoming due and payable to such parties under the terms of their Subcontracts with Contractor from and after the date Client elects to succeed to the interests of Contractor in such Subcontracts. All sums claimed by such Subcontractors to be due and owing for Work performed prior to such date shall constitute debts between Contractor and the affected Subcontractors, and Client shall in no way be liable for such sums; provided, however, that Client may, at its election, pay any sums owed to such

Subcontractors and Contractor shall reimburse Client for such sums upon demand. In the event of any termination of this Agreement pursuant to Section 15.3, Client may, without prejudice to any other right or remedy it may have, at its option, finish the Work by whatever method Client may deem expedient (subject to Client’s legal obligation to mitigate its costs). To the extent the costs of completing the Work after a termination pursuant to Section 15.3, including compensation for additional professional services, exceed those amounts that would have been payable to Contractor under the Agreement to complete the Work if the Agreement had been fully performed, Contractor shall pay the difference to Client upon demand.
