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:

| |    |

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.

Changes in the
Project

9.1 The Owner, without invalidating this
Agreement, may order Changes in the Project within the general scope of this
Agreement consisting of additions, deletions or other revisions, the Guaranteed
Maximum Price, if established, the Contractors Fee, and the Contract Time
Schedule being adjusted accordingly. All such Changes in the Project shall be
authorized by Change Order.

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.

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.

11.3 Owners
Liability Insurance

11.4 Insurance to
Protect Project

11.4.1 The Owner shall purchase and maintain
property insurance in a form and an amount acceptable to the Contractor upon
the entire Project for the full cost of replacement at the time of any loss.
This insurance shall include as named insureds the Owner, the Contractor,
Subcontractors and Subsubcontractors and shall insure against loss from the
perils of Fire, Extended Coverage, and shall include All Risk insurance for
physical loss or damage including, without duplication of coverage, at least
theft, vandalism, malicious mischief, transit, collapse, explosion, testing,

insurance shall include coverage during start-up and commissioning of the
project. The Owner will increase limits of coverage, if necessary, to reflect the
estimated replacement cost. The Owner will be responsible for any co-insurance
penalties or deductibles. If the Project covers an addition to or is adjacent

or use a portion or portions of the Project prior to the Operational Completion
thereof, such occupancy shall not commence prior to a time mutually agreed to
by the Owner and the Contractor and to which the insurance company or companies

policies. This insurance shall not be cancelled or lapsed on account of such
partial occupancy. Consent of the Contractor and of the insurance company or
companies to such occupancy or use shall not be reasonably withheld.

11.4.2 The Owner shall purchase and maintain such
boiler and machinery insurance as may be required or necessary. This insurance
shall include the interests of the Owner, the Contractor, the Subcontractor and
Subsubcontractors in the Work.

11.4.3 The Owner shall purchase and maintain such
insurance as will protect the Owner and the Contractor against loss of use of
Owners property due to those perils insured pursuant to Subparagraph 9.4.1.
Such policy will provide coverage for expenses of expediting materials,
continuing overhead of the Owner and the Contractor, necessary labor expense
including overtime, loss of income by the Owner and other determined exposures.
Exposures of the Owner and the Contractor shall be determined by mutual
agreement and separate limits of coverage fixed for each item.

policies with the Contractor before an exposure to loss may occur. Copies of
any subsequent endorsements will be furnished by the Contractor. The Contractor
will be given sixty (60) days notice of cancellation, non-renewal, or any
endorsements restricting or reducing coverage. If the Owner does not intend to
purchase such insurance, he shall inform the Contractor in writing prior to the
commencement of the Work. The Contractor may then affect insurance which will
protect the interest of himself, the Subcontractors and their Subsubcontractors
in the Project, the cost of which shall be added to the Guaranteed Maximum
Price by Change Order. If the Contractor is damaged by failure of the Owner to purchase
or maintain such insurance or to so notify the Contractor, the Owner shall bear
all reasonable costs properly attributable thereto.

of Subrogation

11.6.1 The Owner and Contractor waive all rights
against each other, the Architect/Engineer, Subcontractor and Subsubcontractors
for damages caused by perils covered by insurance provided under Paragraph

against each other, the Architect/Engineer, Subcontractor and Subsubcontractors
or loss or damage to any equipment used in connection with the Project which

12.1.1 If the Project is stopped for a period of
thirty (30) days under an order of any court or other public authority having
jurisdiction, or as a result of an act of government, such as a declaration of
national emergency making materials unavailable, through no act or fault of the
Contractor or if the Project should be stopped for a period of thirty (30) days
by the Contractor for the Owners failure to make payment thereon, then the
Contractor may, upon seven days written notice to the Owner, terminate this
Agreement and recover from the Owner payment for all Work executed, the
Guaranteed Maximum Price earned to date, and for any proven loss sustained upon
any materials, equipment, tools, construction equipment and machinery,
including reasonable profit and damages.

12.2 Owners Right to
Perform Contractors Obligations and Termination by the Owner for Cause

12.2.1 If the Contractor fails to perform any of
his obligations he assumes to perform Work with his own forces, the Owner may,
after seven days written notice, during which period the Contractor fails to
perform such obligation, make good such deficiencies. The Guaranteed Maximum
Price, if any, shall be reduced by the reasonable cost to the Owner of making
good such deficiencies.

12.2.2 If the Contractor is adjudged a bankrupt,
or if he makes a general assignment for the benefit of his creditors, or if a
receiver is appointed on account of his insolvency, or if he persistently or
repeatedly refuses or fails, except in cases for which extension of time is
provided, to supply enough properly skilled workmen or proper materials, or if
he fails to make proper payment to Subcontractors or for materials or labor, or
persistently disregards laws, ordinances, rules, regulations or orders of any
public authority having jurisdiction, or otherwise is guilty of a substantial
violation of a provision of this Agreement, then the Owner may, without
prejudice to any right or remedy and after giving the Contractor and his
surety, if any, thirty days written notice, during which period the Contractor
fails to cure the violation, terminate the employment of the Contractor and
take possession of the site and of all materials, equipment, tools,
construction equipment and machinery thereon owned by the Contractor and may finish the Work by
whatever reasonable method he may deem expedient. In such case, the Contractor
shall not be entitled to receive payment until the Work is finished nor shall
he be relieved from his obligations assumed under Article 6.

12.3 Termination
by Owner Without Cause

12.3.1 If the Owner terminates the Agreement
other than pursuant to 12.2.2, he shall pay the Contractor the total of: (a.)
Costs incurred by the Contractor in performing the Project, including initial
costs and preparatory expenses; (b.) Costs incurred in settling and paying
termination claims under terminated subcontracts; (c.) Accounting, legal,
clerical and other expenses incurred as a result of termination; (d.) Storage,
transportation demobilization and other costs incurred for the preservation,
protection or disposition of material and equipment on the Project; (e.) Any
other necessary and reasonable costs incurred by the Contractor as a result of
the Owners termination of this Agreement; (f.) Overhead at ten percent (10%)
of the total amount of (a.) through (e.) above; profit at ten percent (10%) of
the total amount of (a.) through (f.) above, as adjusted pursuant to Articles 6
and 9. In calculating the amount due the Contractor under this clause, a
deduction shall be made for all payments to the Contractor under this
Agreement. Contractor has a fiduciary responsibility to the Owner to minimize
costs of termination and maximize return of all down payments.

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.

the Contract Price.

The total aggregate
liability of Seller with respect to liquidated damages (Delivery and
Performance) shall not exceed in total 7.5% of the Contract Price

Breakdowns, not caused by
Seller supplied Equipment will not be considered a failure of the Seller supplied
portion of the Plant. Process interruptions of less than four (4) hours caused
by the Equipment shall not be considered as a failure of the continuous
performance guarantee. If the Plant fails to meet the performance guarantees
during a qualifying five (5) day performance test, Seller will have sixty (60)
days to make corrective action and repeat the performance test.

Seller will be responsible
for liquidated damages which will be the Buyers exclusive remedy in each case.

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.

4.Delivery.Time is an important consideration for both parties
under this Purchase Order. Seller will notify Buyer at once if Seller cannot
fill this order or if shipment or performance is delayed for any cause
whatsoever. If delivery of terms or services or both is not completed by the
time promised, Buyer, without liability and in addition to its other rights and
remedies, may terminate this Purchase Order by notice effective when received
by Seller as to items not yet shipped or services not yet rendered and may
purchase substitute items or services or both and charge Seller with all
losses. 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. Seller warrants that prices shown on this Purchase Order are
complete, and no additional charges of any type (including, without limitation,
charges for shipping, packaging, labeling, custom duties, taxes, storage,
insurance, boxing and crating) will be added without Buyers express written
consent.

6. Taxes.Seller shall include sales and use taxes in the
Purchase Price of all goods and services provided to Buyer and shall separately
account for such taxes. Buyer is exempt from sales and use taxes on the
purchase of certain equipment to be incorporated into the Project to the extent
allowed by law. Buyer will provide Seller with an exemption certificate or
information which authorizes tax exempt purchases for this Project. The
Purchase Price shall be adjusted (reduced) for any such exempt taxes.

7.Warranty.Seller warrants that all items or services or both
furnished under this Purchase Order will conform to all samples,
specifications, drawings, proposals, performance guarantees, warranties, and
appropriate standards will be free from defects in material and workmanship.
Seller warrants that all such items and services will conform to all statements
made on the containers or labels for such items or services or both, and that
all items will be adequately contained, packaged, marked and labeled. Seller
warrants that all such items when used and maintained.

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.

even the warranties will continue for twenty-four (24) months from initial
operation but not more than thirty (30) months from the date of delivery)
provided that:

(a)
the equipment is installed in accordance with Sellers specifications and
instructions and is used and maintained normally and properly in accordance with
Sellers instructions as to maintenance and operation, set forth in written
operation and maintenance manuals and instruction sheets furnished by Seller;

(b)
the equipment is used for processing feed stock consistent with the feed stock

Seller;

(d)

startup, operation and maintenance.

This warranty shall not cover
(i) any equipment furnished by Buyer or any third party (other than a
subcontractor of Seller), (ii) any defects arising from corrosion, abrasion,
use of unsuitable lubricants, or negligent attendance or faulty operation,
(iii) ordinary wear and tear, or (iv) any defects caused by errors on the part

PURPOSE (OTHER THAN THE PURPOSE STATED IN THE BUYERS SPECIFICATIONS OR THIS
CONTRACT), SUITABILITY OR PERFORMANCE. No other promise or affirmation of fact

the equipment) shall constitute a warranty of Seller or give rise to any
liability or obligation on the part of Seller.

8. Technical Support.Seller shall provide appropriate and
trained technical support throughout the Project and the warranty period as
necessary to ensure proper installation, commissioning, and use of all
equipment and materials purchased by Buyer. Seller shall provide three sets of

including without limitation the manufacture, delivery, installation, and
operation of the plant, equipment, goods, or system for use by Buyer, without
conflict with the rights of others. Seller further warrants that it has the
right to sublicense all intellectual property, technology, and processes to
operate the plant, equipment, goods, or systems and hereby assigns and
transfers to Buyer the right and license to use any such intellectual property,
technology, processes and software, including third-party software or firmware,
used to operate the plant equipment, goods, or system supplied to Buyer other
than Sellers proprietary software, which Seller licenses Buyer to use solely
for the operation and maintenance of the equipment or system purchased from
Seller under this Purchase Order.

10.Indemnification.Seller will defend and indemnify Buyer
against all damages, liabilities, claims, losses and expenses (including
attorneys and witnesses fees and litigation costs) to the extent arising or
resulting in any way from any defect in the items or services or both purchased

(including the costs and attorneys fees of any suit or claims related thereto)
incurred by Seller to the extent of persons being injured or property being
damaged directly or indirectly as a result of such failure. Buyer also agrees
to indemnify and save Seller harmless from, any claim, liability or obligation
incurred by Seller to the extent resulting from persons being injured or
property being damaged due to use of Seller equipment for materials or products

not specifically authorized in writing by Seller or due to changes in the
Seller equipment made by Buyer without Sellers specific written authorization.

11.Insurance.Seller will maintain the following insurance coverage,
and agrees that such insurance will not be terminated until the work is

providing for payment to the Seller and Buyer as their respective interests may

any right of contribution by any insurance that may be carried by Buyer.

12. Controlled Insurance Program.Buyer is

alleged patent or copyright infringement and claims arising from similarity in
design, trademark or appearance of items or services or both furnished
hereunder; provided, however, that such indemnity does not include any

Seller. This obligation to indemnify and hold harmless will extend to all
expenses, losses, royalties, lost profits and damages (including, without
limitation, litigation costs, attorneys and witnesses fees and settlement
payments) resulting from any such suit or proceeding, threatened or brought.
Upon receipt of notice from Buyer, Seller promptly will assume full
responsibility to defend and to resolve any such suit or proceeding brought or
threatened against Buyer and its agents. Seller will notify Buyer in writing of
the selection of counsel for any such suit or proceeding, and will change
counsel upon Sellers receipt, within 3 business days of Buyers written notice
specifying Buyers good faith reasons for objecting. Buyer, at its option and
expense, may be represented by, and actively participate through, its own
counsel in any such suit or proceeding; Sellers counsel will cooperate fully
with Buyers counsel in such event. All these obligations will survive the
termination of this Purchase Order.

14. Inspection; Rejection.Payment for the
items or services or both will not constitute acceptance of the goods or
services provided by Buyer. Seller will not substitute any items or services or
both without Buyers prior written approval. Buyer may count, test and inspect
all items and services furnished hereunder and reject any such items and
services which are in excess of quantities ordered, defective or nonconforming.
All or part of such rejected items may be returned at Sellers expense,
including, without limitation, all transportation and handling costs. All or
part of such rejected services may be replaced or completed at Sellers
expense. Nothing in this Purchase Order will relieve Seller from its
obligations of testing, inspection and quality control.

15.Payment.Payment may be withheld, in whole or in part, to
protect Buyer from loss on account of the following: a) defective equipment,
materials, or work of Seller, which is not remedied; b) claims filed by third

damage to the Buyer or another person or entity caused by Seller or Sellers
subcontractors or material suppliers.

for Final Payment, which shall be accompanied by (a) all manuals or operations
books or similar information, (b) as built drawings of Sellers work, and (c)
properly executed final lien waiver and release from Seller. Buyer shall make

Addendum A-2
Performance Warranty & 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, Addendum A-1 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

|E) | The
 direction of commissioning of the erected unit has been carried out by the
 engineers of the SELLER and with
 support of educated and experienced staff of the BUYER. The staff of the BUYER
 has to follow and carry out all instructions as given by the specialists of
 the SELLER.
|   |                                                                                                                                                                                                                                                                                            
|F) | The project
 conditions at the time of signing the contract have not been changed or the BUYER has informed the SELLER about
changes/modifications with
 the acceptance of the SELLER.                                                                                                     

The Performance Warranty (quality, capacity, consumption of electrical
power, process water, process steam, sodium hydroxide, phosphoric acid) becomes
automatically null and void if one of the above mentioned conditions have not
been fulfilled and the BUYER is
responsible for that.

In principle, the operation of the plant with other types of crude
vegetable oils and utilities not in conformity with the types mentioned in this
contract is possible, but only under the condition that the SELLER will not be held responsible for any
faults or damages of the unit.

The processing of other types of oil is
possible but in this case the specification of the degummed oil and the
consumption of utilities will change.

 cycle, 480 volt secondary from the main transformer furnished by the local
 utility company. The electrical
 contractor (The Ken Bratney Companys responsibility) will provide
 underground service from a high voltage switch (supplied by The Ken Bratney
 Co.) to the primary side of the transformers and from the secondary side of
 the transformers to the motor control center switch panels. This will further
 include power switching gear, motor control center and a backup power (UPS)
 system as required for the operation of the control system. Electrical

 galvanized) with insulated sandwich wall panels, pre-engineered roof purlins
 and wall girts fabricated from galvanized sheet stock, metal sheeting and
 vinyl-reinforced insulation in the roof.
 The structure is approximately 50 wide x 95 long x 80 tall. The grade level will be concrete on grade
 with the intermediate levels structural steel with bar grating. The structure
 under the separators will be a concrete over steel framing. This building
 will have fire sprinklers at each level. Two fire exit stairwells will
 provide access to each level of the structure with exits at grade direct to
 the outside.
