5.2 The work in this Agreement will occur and reach several milestones prior to Final Completion Status. Namely:

- Mechanical Completion

- Commissioning Completion

- Operational Completion

- Final Completion

Mechanical Completion – Contractor has completed erection in accordance with drawings and specifications, applicable codes, and met all other requirements of this agreement. “Mechanical Completion” applies to mechanical equipment, piping, electrical, instrumentation, buildings, infrastructure, and all areas of the site.

It is recognized that painting, paving, insulation, as well as final clean up must be completed by Contractor before the installation is deemed finally complete. At the time of “Mechanical Completion”, this work may not be complete, but should be in a sufficiently advanced state of completion so as to not unreasonably interfere with subsequent activities nor affect minimum safety and environmental requirements.

Commissioning Completion – The commissioning phase of work includes the checking and preparation of units or systems for operation, the checking of controls and automation, interlock testing, system purging and flushing, utility unit start-ups, system adjustments, water circulation and other activities. Commissioning prepares the units for initial charging of raw materials, catalysts, etc. and eventual start of the chemical operations.

Operational Completion – Operational Completion occurs when one or more periods of not less than 48 hours in duration occur where the capacity of the production unit has exceeded 90% of nameplate (272 mton per day Biodiesel) and a performance warranty test has been completed.

Final Completion – This milestone occurs when:

	a)	Plant has met Operational Completion status or the Contractor has agreed to pay Owners liquidated damages for performance deficiencies;
	b)	Contract has completed all work;
	c)	Contractor has removed all project equipment, waste and surplus materials from the site;
	d)	Contractor has delivered to Owners all documentation required under the agreement;
	e)	Contractor has completed all punch list items.

5.3 Mechanical Completion status is expected within 15 calendar months from the date of “Beginning of Performance”.

Operational Completion status is expected within 17 calendar months from the date of “Beginning of Performance”.

Final Completion is expected with 18 calendar months from the date of “Beginning of Performance”.

5.4 If the Contractor is delayed at any time in the progress of the Project by any act or neglect of the Owner or by any separate contractor employed by the Owner, or by changes ordered in the Project, or by fire, unusual delay in transportation, adverse weather conditions not reasonably anticipated, unavoidable casualties, or any causes beyond the Contractor’s control, or a delay authorized by the Owner, then the Date for Operational Completion shall be extended by Change Order for the period caused by such delay.

5.5 Failure of the Contractor to complete the Project by the Operational Completion Date shall result in a penalty in the amount of $7,500.00 a day for each day Contractor fails to meet the scheduled date.

Both parties agree to this amount since specific dollar amounts for damages for each such violation are impossible to calculate. Any and all penalties will be capped at $225,000.00 subject to Owner’s Lender’s approval.

ARTICLE 6

Guaranteed Maximum Price

6.1 The Contractor guarantees that the maximum price to the Owner for the Cost of the Project as set forth in Article 8, and the Contractor’s Fee as set forth in Article 7, will not exceed forty-nine million five hundred thousand Dollars ($49,500,000.00 ), which sum shall be called the Guaranteed Maximum Price.

9.1.1 A Change Order is a written order to the Contractor signed by the Owner or his authorized agent and issued after the execution of this Agreement, authorizing a Change in the Project and/or an adjustment in the Guaranteed Maximum Price, the Contractor’s Fee or the Contract Time Schedule. Each adjustment in the Guaranteed Maximum Price resulting from a Change Order shall clearly separate the amount attributable to the Cost of the Project and the Contractor’s Fee.

Guaranteed Max Price
Revised 06/18/2007 Page 15 of 23

9.1.2 The increase or decrease in the Guaranteed Maximum Price resulting from a Change in the Project shall be determined in one or more of the following ways:

9.1.2.1 By mutual acceptance of a lump sum properly itemized and supported by sufficient substantiating data to permit evaluation; or

9.1.2.2 By unit prices stated in this Agreement or subsequently agreed upon; or

9.1.2.3 By mutually agreed to costs plus Contractor’s fee of 10%; or

9.1.2.4 By method provided in Subparagraph 9.1.3.

9.1.3 If none of the methods set forth in Clauses 9.1.2.1 through 9.1.2.3 is agreed upon, the Contractor reserves the right to not go forward with the change.

9.1.4 If unit prices are stated in this Agreement or subsequently agreed upon, and if the quantities originally contemplated are so changed in a proposed Change Order or as a result of several Change Orders that application of the agreed unit prices to the quantities of Work proposed will cause subsequent inequity to the Owner or the Contractor, the applicable unit prices and the Guaranteed Maximum Price shall be equitably adjusted by mutual consent.

9.1.5 Should concealed conditions encountered in the performance of the Work below the surface of the ground or should concealed or unknown conditions in an existing structure be at variance with the conditions indicated by the Drawings, Specifications or Owner-furnished information or should unknown physical conditions below the surface of the ground or should concealed or unknown conditions in an existing structure of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in this Agreement, be encountered, the Guaranteed Maximum Price and the Contract Time Schedule shall be equitably adjusted by Change Order upon claim by either party made within reasonable time after the first observance of the conditions.

9.2 Claims for Additional Cost or Time

9.2.1 If the Contractor wishes to make a claim for an increase in Guaranteed Maximum Price, or increase in his Fee or an extension in the Contract Time Schedule, he shall give the Owner written notice thereof within a reasonable time after the occurrence of the event, giving rise to such claim. This notice shall be given by the Contractor before proceeding to execute the Work, except in an emergency endangering life or property in which case the Contractor shall act, at his discretion, to prevent threatened damage, injury or loss. Claims arising from delay shall be made within a reasonable time after the delay. Increases based upon design and estimating costs with respect to possible changes requested by the Owner shall be made within a reasonable time after the decision is made not to proceed with the change. No such claim shall be valid unless so made. If the Owner and the Contractor cannot agree on the amount of the adjustment in the Guaranteed Maximum Price, the Contractor’s Fee or Contract Time Schedule, it shall be determined pursuant to mediation. Any change in the Guaranteed Maximum Price, the Contractor’s Fee or Contract Time Schedule resulting from such claim shall be authorized by Change Order.

Test Run Procedures

The warranty figures are valid for operation of the plant at nominal capacity and take into account the relevant tolerances of ***%.

The above performance data are valid on the condition that the plant is erected according to our instructions and start-up is conducted by Westfalia’s personnel.

If the performance test run cannot take place during the start-up period for reasons not imputable to Westfalia, then this obligation to demonstrate fulfillment of warranty shall be deemed satisfied if the plant operated continuously under warrantee conditions. The plant shall then be regarded as having been taken over by Purchaser.

In case Westfalia should fail to prove the aforementioned warranties for reasons solely attributable to Westfalia, Westfalia shall at their expense make, as soon as possible the necessary modifications to the design of the plant and supply the equipment to modify the plant. Purchaser shall provide all facilities necessary for carrying out such modifications.

After completion of the modifications further performance test runs shall be carried out under the same conditions as stated above.

If the repeated final performance test run fails to fulfill the warranties for reasons solely attributable to Westfalia, Westfalia shall pay liquated damages agreed upon.

With the payment of the liquidated damages the plant shall be considered as being accepted by Purchaser.

If, for reasons not imputable to Westfalia, neither the warranty test-run nor the continuous operation under warranty conditions is performed successfully within *** months after the mechanical completion or *** months after the coming into force of the contract, whichever occurs earlier, the plant is considered as being accepted. Westfalia may give support to Purchaser in attaining the warrantee values after this period, at terms and conditions to be agreed upon in due time.

All warranties are valid under the condition that Purchaser’s services and supplies will be rendered in accordance with our documentation and process requirements.

Performance test runs shall be conducted over a *** (***) day period by Westfalia Separator.

STANDARD TERMS AND CONDITIONS

1. Acceptance; Agreement. Seller and Buyer agree to the express terms of this Purchase Order. In the event that any provision of any invoice, acknowledgment, quotation, or other document whatsoever provided by Seller to Buyer conflicts with the provisions in this Purchase Order, the provisions of this Purchase Order shall control. In the event that any provision in any invoice, acknowledgment, quotation, or other document whatsoever provided by Seller to Buyer attempts to limit Seller’s liability or restrict Buyer’s remedies, such provision shall be inconsistent with this Purchase Order and shall be void and unenforceable. If any term contained in any Order or other form used by Buyer to order goods under this Purchase Order or in any acknowledgment or other form used by Seller is inconsistent with any term of this Purchase Order, this Purchase Order will take precedence unless Buyer agrees to such inconsistent term by a writing, signed by Seller and Buyer, that specifically references this Purchase Order and specifically acknowledges such inconsistency.

2. Termination for Convenience. Buyer, for its convenience, may at any time terminate this order in whole or in part upon 3 days’ written notice to Seller. Upon the receipt of such notice, Seller immediately will stop, and will cause its suppliers and its subcontractors immediately to stop, all work hereunder. Seller will be paid a reasonable termination charge (including a reasonable overhead and profit for such work): the percent of the order price reflecting the amount of the work performed before the termination notice, plus actual direct costs resulting from the termination. Seller will not be paid for any work done after termination nor for any reasonably avoidable costs thereafter incurred by Seller’s or Seller’s subcontractors.

3. Default; Remedies. If Seller fails to perform any of the terms and conditions under this Purchase Order (including, without limitation, breach by late shipment or performance, defects in workmanship or materials or delivery of items which fail to conform to samples or services which fail to conform to guarantees or warranties), Buyer, in its sole discretion and upon seven (7) days’ written notice to Seller, may declare Seller to be in default. If Seller does not commence to remedy all defaults specified in the notice within the 7 days or fails to diligently complete the cure thereafter, Buyer, with further notice may: (a) cancel, in whole or in part, or refuse delivery in whole or in part of, any and all orders then outstanding between Buyer and Seller, and (b) exercise any and all rights and remedies available at law and in equity (subject to the limitations in these Standard Terms and Conditions). If Seller proves to be solely at fault, Seller will bear all Buyers’ attorneys’ and witnesses’ fees and litigation costs incurred in enforcing this Purchase Order.

Delivery of the equipment or goods shall be DDP, point of delivery indicated on Purchase Order. Title shall pass to Buyer upon delivery to the DDP delivery point. Risk of loss or damage shall pass to Buyer only upon Buyer’s final acceptance.

5. Price Warranty. Seller warrants that the prices for all items and services sold hereunder are as favorable as prices currently extended to any other Buyer for similar quality and quantities of the same or similar items or services or both. If Seller reduces its price for such items or services or both during the term of this Purchase Order, Seller will reduce Buyer’s Prices correspondingly.

In accordance with Seller’s instructions will be safe and appropriate for the purpose for which items of that kind are normally used. Seller warrants that such items or services or both will be fit for the purpose set forth in this Contract. Seller’s warranty will survive Buyer’s inspection, testing, acceptance and use. Seller’s warranty runs to Buyer and its successors and assigns. Upon notice from Buyer, Seller will replace or correct defects of any nonconforming items or services or both, promptly and without expense to Buyer. If Seller fails promptly to correct defects in, or to replace, nonconforming items or services or both, Buyer, after reasonable notice to Seller, may make such corrections or replace such items and services and charge Seller for the reasonable costs of doing so. All these obligations will survive the termination of this Purchase Order.

Xxxxxxxx X-0
Xxxxxxxxxxx Xxxxxxxx & Testing
Pretreatment Section - Soy Energy

March 12, 2007

The following information forms the basis for performance testing and certifying the pretreatment section of the Soy Energy facility.

This information does not apply to the testing and certification of the Biodiesel section of the facility. For that section, Xxxxxxxx X-0 is included in the EPC contract.

In this document, the term contract value refers to the financial value of the equipment purchase between Cimbria SKET and Bratney Co.

In the following, “SELLER” is defined as Cimbria SKET working in conjunction with its U.S. agent, Bratney Company. Conversely, “BUYER” refers to the Soy Energy owner/Board of Directors organization.

Performance Testing

As condition for a handing over/taking over of the plant, the SELLER has to carry out a performance test of the pretreatment unit.

For such a performance test, the BUYER has to provide continuously all necessary raw materials and utilities as listed in sufficient quality and quantity as to enable the SELLER to carry out the start-up and commissioning of the pretreatment unit.

The Performance Test Run has to be carried out over a period of 48 hours during continuous operation of the unit under the direction of the SELLER’s engineers and the presence and assistance of the BUYER’s operators and staff.

The detailed conditions for the Performance Test Run will be agreed to between both BUYER and SELLER three (3) days in advance and will be recorded in a separate protocol.

If the quality, quantity and consumption figures mentioned below are achieved during the 48 hours continuous operation, the Performance Test will be declared as fulfilled and both BUYER and SELLER will sign the Acceptance Certification within five (5) working days.

If the Performance test will not meet the requirements under the fault of the SELLER, the SELLER has the right to repeat the test.

The time to repeat such a test and other conditions shall be mutually agreed upon between the BUYER and the SELLER under consideration of the actual situation at the plant site.

The SELLER is obliged to take all necessary measures to repeat such a Performance Test as quickly as possible and the BUYER has to give his support as being necessary for the performance test.

Performance Warranty and Penalties

The SELLER shall be liable for the processing capacity of the unit, the quality of the final products as well as for the consumption of utilities (total electrical power, total process steam, total water consumption, total phosphoric consumption, total consumption of sodium hydroxide) according to listing below under the condition that the BUYER provide sufficient quantity and quality of vegetable oil and utilities as specified below.

The Performance Warranty is only valid in connection with the conditions as mentioned below.

Should, however, the quality of final products, the processing capacity and the consumption of utilities not attain required levels, and the SELLER is responsible for that, the SELLER is obliged to repair or replace at his choice those parts of the unit which cause the insufficient character of the unit.

Should the plant not reach the contracted and guaranteed parameters the SELLER has to pay liquidated damages (penalties) as follows:

1.	Quality of the final products
	If the Plant does not reach the contracted quality of the final products (technically refined vegetable oil; degummed and deacidified) under responsibility of the SELLER, the SELLER is obliged to take immediately all necessary measures to bring the unit into successful operation.
	The SELLER is obliged to repair or replace at his choice those parts of the Plant which cause the insufficient quality of the contracted final product.
