NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth, the parties agree as follows:

ARTICLE 1                                Definitions

(1.1)                         The defined terms in the License Agreement shall have the same meanings when used herein and shall apply to this Agreement.

(1.2)                         The terms defined in Schedule A attached hereto shall, for all purposes of this Agreement, have the meanings specified in said Schedule A.

[********] Material has been omitted pursuant to request for confidential treatment and such material has been filed separately with the Securities and Exchange Commission.

ARTICLE 2                                Consideration and Scope of Work

(2.1)                         Consideration.  CVP hereby agrees to perform all of its obligations required by this Agreement and the License (collectively, the “Core Agreements”).

(2.2)                         Description of Work.  CVP shall provide the engineering and other services required of it as set-forth and described in the Schedules B and D attached hereto.

ARTICLE 3                                Application of Process Guarantees

(3.l)                            The Process Guarantees (as defined in Article 4) shall apply to BSE’s Monroe, Wisconsin facility (the “Plant”) only when the Project is completed including without limitation, the procurement and installation of all equipment in accordance with the engineering design specifications and instructions.

(3.2)                         When the Process Guarantees are deemed met and satisfied as provided in Article 6 or Schedule C, such Process Guarantees shall no longer apply to the Plant and CVP’S obligations with respect thereto shall be deemed satisfied in full and shall cease.

ARTICLE 4                                Process Guarantee

CVP guarantees that during the performance test described in Article 6 (the “Performance Test”), the Plant will process fresh substrate charge to produce corn germ, corn fiber, corn protein concentrate, CO₂, and “anhydrous alcohol,” according to the specifications set forth in Schedule C attached hereto (the “Process Guarantee”).  CVP acknowledges that, during the initial Start-up, the Plant will temporarily produce HI-PRO DDGS which will have similar specifications to the DDGS being produced currently by BSE, however, such temporary production of HI-PRO DDGS is not part of the Process Guarantee or the Performance Test.  In the event that the Plant does not, during the Performance Test, meet or exceed the Process Guarantee, then CVP covenants and agrees to take any reasonable action necessary, at its own expense, to modify or adjust the Project such that the Process Guarantee is met.  CVP hereby represents and warrants that the Project as contemplated by the Core Agreements shall not adversely effect the Plant’s current operations including the production of ethanol or carbon dioxide (including, without limitation, causing the Plant to cease operations at any one time for more than 72 hours in aggregate).  As BSE’s sole and exclusive remedy, should the Plant not meet the Process Guarantee at the conclusion of the last of the Performance Tests permitted under Article 6 hereof, subject to the parameters set forth in Schedule D hereto, due to material fault of CVP, CVP shall, within sixty (60) days after the submission by CVP of the results of such Performance Test as required under Article 6 hereof, pay to BSE as liquidated damages, at the office of BSE designated on Page 1 of this Agreement, in lawful money of the United States of America, a sum of money calculated pursuant to Schedule C.

ARTICLE 5                                Start-Up Assistance; Training

(5.1)                         Start-up shall occur in accordance with the Master Schedule approved by BSE.   “Start-up” shall mean the commencement of operations by the Plant.  CVP shall give at least thirty (30) days notice in writing to BSE specifying the estimated date of completion of the

2

Upgrade of the Plant. CVP’S senior technologists shall be in attendance at the Plant at least two (2) weeks prior to Start-up, as necessary, to inspect the Plant to determine if the Plant is ready to operate and that the conditions as set forth in Article 3.1 have been met.

(5.2)                         CVP shall use its best efforts to assist BSE in the start-up of the Plant in order to establish operating conditions, and to carry out the Performance Test; provided, however, that regardless of the effort used, the Process Guarantee shall be absolute.  CVP shall supervise and provide technical and operational training for representatives of BSE with respect to the operation of the Plant consistent with the Licensed Process to ensure that such representatives of BSE are fully trained in the operation of the Plant consistent with the Licensed Process.  CVP’S duty of supervision and training under this Section is limited to the operation of Plant consistent with the Licensed Process and does not include, or extend to any other matters, including but not limited to employee safety, employee conduct or general machine operation.  CVP’S duty to provide training and supervision shall terminate upon completion of satisfactory training of BSE’s representatives and the successful completion of a Performance Test, unless otherwise extended by mutual agreement of BSE and CVP.  Notwithstanding the above, CVP shall be responsible for managing, directing and coordinating the Performance Test.

(5.3)                         As part of CVP’S training of representatives of BSE, and prior to the commencing of Start-up operations, CVP shall provide a Process Operation Manual, as described in Schedule A attached hereto, that will set-forth the proper operation and maintenance of the Plant consistent with the Licensed Process.

ARTICLE 6                                Performance Test

(6.l)                            After the Start-up described in Article 5 and the Plant having reached nameplate capacity of 52 million gallons per year for a period of seven (7) consecutive days (as calculated on the basis of a 365 day year), but not later than ninety (90) days from the later of the date of completion of the Start-up, CVP shall notify BSE in writing that the Plant is ready for the Performance Test (the “Performance Test Notification”).

(6.2)                         Upon receipt of the Performance Test Notification, BSE shall have the obligation of calling for the Performance Test by setting a date for same not less than seven (7) days nor more than thirty (30) days from the date of the Performance Test Notification.  Delays in the beginning of the Performance Test caused by other portions of the Plant outside the “Battery Limits” of the Licensed Process as described on Schedule D attached hereto will not be deemed to constitute a material cause for a delay of the Performance Test, unless agreed to by CVP and BSE.

(6.3)                         The Performance Test shall be conducted by CVP, provided that BSE shall cause its representatives to take all reasonable actions to assist CVP in satisfactorily completing the Performance Test.  The Performance Test shall be deemed to have been met as soon as the Plant has satisfied the requirements of the Process Guarantee and Section 6.5.

(6.4)                         In the event that the Plant fails a Performance Test then CVP shall promptly take all actions reasonably necessary to repair the deficiency which resulted in such failure at its own

3

expense.  Thereafter, CVP shall reasonably promptly conduct additional Performance Tests and make additional repairs or modifications as reasonably necessary and at its own expense until the Plant successfully meets the Process Guarantee.

(6.5)                         Within two (2) business days after completion of each Performance Test, CVP shall submit to BSE in writing the results thereof.  If CVP determines that the Process Guarantee has been met, then CVP shall certify in writing that the Process Guarantee relating to such Performance Test has been met in all regards (the “Certification”). Such Process Guarantee shall be deemed to have been met if CVP provides the Certification and if BSE, within sixty (60) days after receiving the Certification, does not respond in writing to CVP detailing in what respect, in BSE’S opinion, such Process Guarantee has not been met.  If BSE notifies CVP that the Process Guarantee, in BSE’s reasonable judgment, has not been met, then CVP, at its cost and expense, shall make such corrections as are reasonably necessary to ensure that the Plant complies with the Process Guarantee.

(6.6)                         BSE shall furnish, at no cost to CVP, fresh substrate charge, yeast culture, enzymes, chemicals, utilities, operating and maintenance personnel, minor (nonmaterial) maintenance materials and necessary services, such as adequate laboratory inspection and minor (nonmaterial) operating supplies as are required for the operation of the Plant in order to meet the Process Guarantee as herein made. BSE shall be responsible to process fresh substrate charge at a rate as reasonably required by CVP during the Performance Test, provided that such rate shall not exceed 100% of daily capacity (calculated at 52 million gallons of ethanol per year).

(6.7)                         Notwithstanding any other provision of the Core Agreements, CVP covenants and agrees that the Plant shall be fully upgraded and operational, having successfully passed its Performance Test in accordance with the Master Schedule approved by BSE, unless otherwise extended by mutual written agreement of BSE and CVP.

ARTICLE 7                                Modifications

(7.1)                         Prior to meeting the Process Guarantee, CVP shall have the right to make such reasonable changes, at its own cost and expense, to the Project as are required to meet the Process Guarantee with the prior written consent of BSE (which consent shall not be unreasonably withheld, conditioned or delayed).  CVP represents that it has the authority to make such changes and that such changes shall be subject to all representations and warranties stated in the Core Agreements.  CVP will furnish the necessary design engineering documentation showing such changes at no charge to BSE.

(7.2)                         In order to enable CVP to determine, prior to making such modifications to the Plant, the nature of the defects in the Plant, if any, BSE shall, upon reasonable notice and request by CVP, operate the Plant under commercially reasonable and safe operating conditions as may be reasonably specified by CVP from time to time during the Performance Test.

(7.3)                         In the event BSE fails to operate and maintain the Plant in substantial accordance with the operation manual provided by CVP, CVP shall provide written notice of such failure to BSE and BSE shall cure such failure.  Notwithstanding the above, if the reason that BSE failed

4

to operate and maintain the Plant in material accordance with the operation manual provided by CVP is because such operation and maintenance would result in a material adverse effect on the Plant, then CVP shall modify said operation manual so that compliance with the operation manual will not result in a material adverse effect on the Plant.

(7.4)                         Except as may otherwise be provided herein, BSE shall assume all expenses of operation of the Plant, and shall have complete control of the Plant at all times.

ARTICLE 8                                Guarantee

(8.1)                         Subject to the limitations in Section 8.2 below, CVP hereby guarantees the prompt, full and faithful discharge of each and every obligation, term, condition and agreement of CVP in the Core Agreements.

(8.2)                         Notwithstanding any other provision of the Transaction Documents, including without limitation, the License, in no event shall CVP’s aggregate liability under the Transaction Documents exceed[********].  In no event shall CVP be responsible for any punitive, incidental, consequential, exemplary or lost profits damages.

ARTICLE 9                                Security

In order to secure CVP’s obligations under this Agreement, CVP agrees as follows:

(9.1)                         Notwithstanding anything to the contrary in the License, BSE may withhold five percent (5%) of each payment due under the Technical Information Fee, said retainage to be paid to CVP immediately upon completion of the Performance Test to the reasonable satisfaction of BSE.

(9.2)                         CVP shall cause Centrisys Corporation, AMG, Inc. and QTI to execute separate limited guarantees in favor of BSE, guaranteeing CVP’s payment obligations under this Agreement, said limited guarantees to be limited to no more than [********] each.  Each of said limited guarantees shall be terminated immediately upon completion of the Performance Test to the reasonable satisfaction of BSE.

ARTICLE 10                         Insurance

(10.1)                   CVP agrees, at its expense, to maintain in full force and effect during the entire time any work is performed at the Plant by CVP or the employees, agents or subcontractors of either, a policy or policies of public liability and property damage insurance under which BSE are named as additional insured.  The policy shall provide that BSE will receive 30 day written notice of any material change in policy conditions, non-refundable or cancellation.  The minimum limits of coverage of such policies in the aggregate shall be Two Million and no/100 Dollars ($2,000,000.00) for injury or death to any one person, and One Million and no/100 Dollars ($1,000,000.00) with respect to damage to property.
