the means, methods, sequences and techniques of construction.

     3.4 GOVERNMENT APPROVALS AND PERMITS. Except as identified in Exhibit C and
with respect to items identified as Owner's responsibility, in Exhibit G (which
items shall be obtained by Owner pursuant to Section 4.5), Design-Builder shall
obtain and pay for all necessary permits, approvals, licenses, government
charges and inspection fees required for the prosecution of the Work by any

                                    ARTICLE 6

                   COMMENCEMENT AND COMPLETION OF THE PROJECT

     6.1 WORK SCHEDULE. Design-Builder shall prepare and submit a schedule for
the execution of the Work to Owner. The schedule ("Work Schedule") shall
indicate the dates for the start and completion of the various stages of Work,
including the dates when Owner's obligations are required to be complete to
enable Design-Builder to achieve the Contract Time(s). The Work Schedule shall
be revised as required by conditions and progress of the Work but such revisions
shall not relieve Design-Builder of its obligations to complete the Work within
the Contract Time(s), unless such revisions to the work Schedule are the result
of any direct or indirect delay in the completion of Owner's obligations. Then
Design-Builder shall be relieved of its obligations to complete the Work within
the Contract Time(s) for completion of the Work shall be extended accordingly
without penalty to Design-Builder.

     6.2 NOTICE TO PROCEED; COMMENCEMENT. The Work shall commence within five
(5) days of Design-Builder's receipt of Owner's written valid notice to proceed
("Notice to Proceed") unless the parties mutually agree otherwise in writing.
The parties agree that a valid Owner's Notice to Proceed cannot be given until:
[ * ] Owner and Designer mutually agree that time is of the essence with respect
to the dates and times set forth in the Contract Documents. Design-Builder must
receive a valid Owner's Notice to Proceed within 180 days of the signing of this
Agreement; otherwise, the Contract Price referred to in Section 9.1 is subject
to a price increase.

          6.2.1 Owner shall provide the following within 90 days of
Design-Builder's receipt of Owner's valid Notice to Proceed, as described in
Section 6.2 above of this Agreement:

     -    Owner shall determine its water supply and pretreatment system design
          and provide Design-Builder with a detailed design, and

[ * ] Portions omitted pursuant to a request for confidential treatment and
      filed separately with the Securities and Exchange Commission.


                                       12
<PAGE>

     -    Owner shall provide the name of its property/all risk insurance
          carrier and the specific requirements for fire protection.

The two bulleted requirements referred to above are further detailed in Exhibit
C. The Scheduled Substantial Completion date will likewise be extended a
corresponding amount of days for each day Owner exceeds the 90-day timeframe
referred to above in Section 6.2.1.

     6.3 PROJECT START-UP AND TESTING. Owner shall provide, at Owner's cost,
equipment, tools, instruments and materials necessary for Owner to comply with
its obligations under Exhibit C, raw materials, consumables and personnel,
necessary for start-up and testing of the Plant, and Design-Builder shall
provide supervision, standard and special test instruments, tools, equipment and
materials required to perform component and equipment checkout and testing,
initial start-up, operations supervision and corrective maintenance of all
permanent Plant equipment within the scope of the Work. Notwithstanding the
foregoing sentence, Design-Builder shall be responsible for raw materials and
consumables to the extent such amounts provided by Owner are destroyed or
damaged (as opposed to consumed in the ordinary course of start-up and testing)
by Design-Builder or its personnel during start-up and testing. Design-Builder
shall supervise and direct Owner's employees who shall participate in the
start-up activities with Design-Builder's personnel to become familiar with all
aspects of the Plant. Owner and the Independent Engineer may witness start-up
and testing activities. Performance testing will be conducted in accordance with
the provisions of Section 7.2 hereof.

     6.4 SUBSTANTIAL COMPLETION.

          6.4.1 Substantial Completion of the entire Work shall be achieved no
later than 485 calendar days after the date of the Notice to Proceed, subject to
adjustment in accordance with the Contract Documents hereof (the "Scheduled
Substantial Completion Date").

          6.4.2 "Substantial Completion" is the date on which the Work is
sufficiently complete so that Owner can occupy and use the Project for its
intended purposes. Substantial Completion shall be attained at the point in time
when the Plant is ready to begin operation for its intended use (ethanol
production; i.e., the "grind corn" date).

          6.4.3 PROCEDURES. Design-Builder shall notify Owner in writing when it
believes Substantial Completion has been achieved with respect to the Work.
Within five (5) days of Owner's receipt of Design-Builder's notice, Owner and
Design-Builder will jointly inspect such Work to verify that it is substantially
complete in accordance with the requirements of the Contract Documents. If such
Work is substantially complete, Design-Builder shall prepare and issue a
Certificate of Substantial Completion for the Work that will set forth (i) the
date of Substantial Completion, (ii) the remaining items of Work that have to be
completed before final payment ("the Punch List"), (iii) provisions (to the
extent not already provided in this Agreement) establishing Owner's and
Design-Builder's responsibility for the Project's security, maintenance,
utilities and insurance pending Final Payment, and (iv) an acknowledgment that
warranties with respect to the Work commence on the date of Substantial
Completion, except as may otherwise be noted in the Certificate of Substantial
Completion. Upon Substantial Completion of the entire Work or, if applicable,
any portion of the Work, and Performance Testing, Owner shall release to
Design-Builder all retained amounts relating, as applicable, to the


                                       13

<PAGE>

entire Work or completed portion of the Work, less an amount equal to the
reasonable value of all remaining or incomplete items of Work as noted in the
Certificate of Substantial Completion.

               a) Owner, at its option, may use a portion of the Work prior to
     completion of the entire Work; provided, that (i) a Certificate of
     Substantial completion has been issued for the portion of Work addressing
     the items set forth in Section 6.4.3 above, (ii) Design-Builder and Owner
     have, to the extent required, obtained the consent of their sureties and
     insurers and the appropriate government authorities having jurisdiction
     over the Project, and (i) Owner and Design-Builder agree that Owner's use
     or occupancy will not interfere with Design-Builder's completion of the
     remaining Work in accordance with the Contract Documents.

     6.5 FINAL COMPLETION.

          6.5.1 final Completion of the Work shall be achieved as expeditiously
as reasonably practicable.

          6.5.2 Final Completion shall be achieved when the Owner reasonably
determines that the following conditions have been met:

               a) Substantial Completion has been achieved;

               g) certificates of insurance confirming that required coverages
     will remain in effect consistent with the requirements of the Contract
     Documents; and

               h) the performance test report has been completed according to
     Section 7.2

          6.5.3 After receipt of a Final Application for Payment from
Design-Builder, Owner shall make final payment in accordance with Section 10.3.

          6.5.4 At the time of submission of its Final Application for Payment,

<PAGE>

               a) an affidavit that there are no claims, obligations or liens
     outstanding or unsatisfied for labor, services, material, equipment, taxes
     or other items performed, furnished or incurred for or in connection with
     the Work which will in any way affect Owner's interests;

               b) a general release executed by Design-Builder waiving, upon
     receipt of final payment by Design-Builder, all claims for payment,
     additional compensation, or damages for delay, except those previously made
     to Owner in writing and remaining unsettled at the time of final payment
     provided such general release shall not waive defenses to claims that may
     be asserted by Owner after payment or claims arising after payment;

               c) consent of Design-Builder's surety, if any, to final payment;
     and

               d) all other documents or materials relating to the Project not
     previously provided to Owner, including as-built plans and drawings.

          6.5.5 Upon making final payment, Owner waives all claims against
Design-Builder except claims relating to (i) Design-Builder's failure to satisfy
its payment obligations, if such failure affects Owner's interests, (ii)
Design-Builder's failure to complete the Work consistent with the Contract
Documents, including defects appearing after Substantial Completion, and (iii)
the terms of any special warranties required by the Contract Documents.

     6.6 POST COMPLETION SUPPORT. Adequate personnel to complete all Work within
the guaranteed schedule will be maintained on-site by Design-Builder or a
Subcontractor until Final Completion has been achieved. In addition to
prosecuting the Work until Final Completion has been achieved, Design-Builder or

                                    ARTICLE 7

                               PERFORMANCE TESTING

     7.1 PERFORMANCE GUARANTEE. The Design-Builder guarantees the Criteria
listed in Exhibit A. If there is a performance shortfall, Design-Builder will
pay all design, and construction, and all other costs associated with making the
necessary corrections, including corrections necessary to meet air emissions
standards, except that Owner is responsible for the increased cost(s) related to
the pollution control equipment referred to in Section 9.1. Design-Builder
retains the right to use its sole discretion in determining the method to remedy
any performance related issues.

          7.1.1 If Owner, for whatever reason, prevents Design-Builder from
demonstrating the Performance Guarantee Criteria within 30 days of
Design-Builder's notice that the Project is ready for Performance Testing,
Design-Builder is thereby deemed to have fulfilled all of its


                                       15
<PAGE>

Performance Guarantee obligations listed in Exhibit A.

     7.2 PERFORMANCE TESTING.

          7.2.1 The Design-Builder shall direct and supervise the tests and, if
necessary, the retests of the Plant using Design-Builder's supervisory personnel
and the Air Emissions Tester shall conduct the air emissions test, in each case,
in accordance with the testing procedures set forth in Exhibit A (the
"Performance Tests"), to demonstrate, at a minimum, compliance with the
Performance Guarantee Criteria. Design-Builder shall cooperate with the Air
Emissions Tester to facilitate performance of all air emissions tests.

          7.2.2 No later than thirty (30) days prior to the earlier of Scheduled
Substantial Completion and the Substantial Completion Date, Design-Builder shall
provide to Owner for review a detailed testing plan for Performance Tests (other
than for air emissions). Design-Builder shall notify the Owner five (5) business
days prior to the date Design-Builder intends to commence the Performance Tests
and shall notify the Owner upon commencement of the Performance Tests. Owner and
Independent Engineer each have the right to witness all testing, including the
Performance Tests and any equipment testing, whether at the Site or at the
Sub-contractor's or equipment supplier's premises during the course of this
Agreement. Owner shall bear the costs of providing a witness to any such
testing.

          7.2.3 Design-Builder shall provide to Owner a performance test report
(excluding results from air emissions testing), including all applicable test
data, calculations and certificates indicating the results of the Performance
Tests and within five (5) business days of Owner's receipt of such results,
Owner, Independent Engineer and Design-Builder will jointly inspect such Work
and review the results of the Performance Tests to verify that the Performance
Guarantee Criteria have been met. If Owner reasonably determines that the
Performance Guarantee Criteria have not been met, Owner shall notify
Design-Builder the reasons why Owner determined that the Performance Guarantee
Criteria have not been met and Design-Builder shall promptly take such action or
perform such additional work as will achieve the Performance Guarantee Criteria
and shall issue to the Owner another notice in accordance with Section 7.2.2;
provided however that if the notice relates to a retest, the notice may be
provided no less than two (2) business days prior to the Performance Tests. Such
procedure shall be repeated as necessary until Owner verifies that the
Performance Guarantee Criteria have been met.

                                    ARTICLE 8

                                   WARRANTIES

     8.1 Design-Builder Warranty. Design-Builder warrants to Owner that the
construction, including all materials and equipment furnished as part of the
construction, shall be new, of good quality, in conformance with the Contract
Documents and all Legal Requirements, free of defects in materials and
workmanship. Design-Builder's warranty obligation excludes defects caused by
abuse, alterations, or failure to maintain the Work by persons other than
Design-Builder or anyone for whose acts Design-Builder may be liable. Nothing in
this warranty is intended to limit any manufacturer's warranty which provides
Owner with greater warranty rights


                                       16

<PAGE>

than set forth in this Section 8.1 or the Contract Documents. Design-Builder
will provide to Owner all manufacturers' and Subcontractors' warranties upon the
earlier of Substantial Completion and termination of this Agreement. Owner's
failure to materially comply with all Operating Procedures shall void those
guarantees, representations and warranties, whether expressed or implied, that
were given by Design-Builder to Owner, concerning the performance of the Plant
that are reasonably determined by Design-Builder to be materially affected by
such failure. If Design-Builder reasonably determines that all damage caused by
such failure can be repaired and Owner makes all repairs needed to correct such
damage, as reasonably determined by Design-Builder, such guarantees,
representations and warranties shall be reinstated for the remaining term
thereof, if any, from the date of such repair.

     8.2 CORRECTION OF DEFECTIVE WORK.

          8.2.1 Design-Builder agrees to correct any Work that is found to not
be in conformance with the Contract Documents, including that part of the Work
subject to Section 8.1, within a period of one year from the date of Substantial
Completion of the Work; provided that such one-year period shall be extended for
any part of the Work that is found to be not in conformance with the Contract
Documents for each day that such part of the Work is not operating in conformity
with the Contract Documents, including any time during which any part of the
Work is repaired or replaced pursuant to this Article VIII.

          8.2.2 Design-Builder shall, within seven (7) days of receipt of
written notice from Owner that the Work is not in conformance with the Contract
Documents, take meaningful steps to commence correction of such nonconforming
Work, including the correction, removal or replacement of the nonconforming
Work. If Design-Builder fails to commence the necessary steps within such seven
(7) day period, Owner, in addition to any other remedies provided under the
Contract Documents, may provide Design-Builder with written notice that Owner
will commence or assume correction of such nonconforming Work with its own
forces. If Owner does perform such corrective Work, Design-Builder shall be
responsible for all reasonable costs incurred by Owner in performing such
correction. If the nonconforming Work creates an emergency requiring an
immediate response, the seven (7) day periods identified herein shall be
inapplicable.

     8.3 WARRANTY PERIOD NOT LIMITATION TO OWNER'S RIGHTS. The one-year period
referenced in Section 8.2 above applies only to Design-Builder's obligation to
correct nonconforming Work and is not intended to constitute a period of
limitations for any other rights or remedies Owner may have regarding
Design-Builder's other obligations under the Contract Documents.

<PAGE>

Article 13. The Contract Price includes a Two Million Dollar ($2,000,000)
allowance for pollution control equipment; the purpose for which is to reduce or
control SOx emissions. Design and installation costs shall be at no markup to
Owner, and the $2,000,000 is a maximum not to exceed cost to the Owner. Unless
otherwise provided in the Contract Documents, the Contract Price is deemed to
include all sales, use, consumer and other taxes mandated by applicable Legal
Requirements. Design-Builder and Owner acknowledge that a portion of the Project
is exempt from sales tax, and Design-Builder agrees to reasonably cooperate with
Owner in claiming any applicable refund of sales tax paid by Owner by providing
reasonable documentation directly to the State Tax Agency only. Any refund of
such taxes Owner receives for the Project will be split evenly (50/50) with the
Design-Builder. The Contract Price assumes the use of non-union labor. If Legal
Requirements require Owner or Owner otherwise requires Design-Builder to use
union labor, the Contract Price shall be adjusted upwards to include any
increased costs associated with the use of union labor.

specific amounts Owner intends to withhold, the reasons and contractual basis
for the withholding, and the specific measures Design-Builder must take to
rectify Owner's concerns. Design-Builder and Owner will attempt to resolve
Owner's concerns prior to the date payment is due. If the parties cannot resolve
such concerns, Design-Builder may pursue its rights under the Contract
Documents, including those under Article 19. Notwithstanding anything to the
contrary in the Contract Documents, Owner shall pay Design-Builder all
undisputed amounts in an Application for Payment within the times required by
the Agreement.

applicable, any portion of the Work, pursuant to Section 6.4, Owner shall
release to Design-Builder all retained amounts relating, as applicable, to the
entire Work or completed portion of the Work, less an amount equal to the

Certificate of Substantial Completion, provided that such payment shall only be
made if Design-Builder has met the Performance Guarantee Criteria listed in
Exhibit A

not apply to any amount actually adjudged to be in dispute.

          10.4.2 RIGHT TO SUSPEND WORK. If Owner fails to pay Design-Builder any
undisputed amount that becomes due, Design-Builder, in addition to all other
remedies provided in the Contract Documents, may stop Work pursuant to Section

rate set forth in Section 10.4.1.

     10.5 DESIGN-BUILDER'S PAYMENT OBLIGATIONS. Design-Builder will pay Design
Consultants and Subcontractors, in accordance with its contractual obligations
to such parties, all the amounts Design-Builder has received from Owner on
account of their work. Design-Builder will impose similar requirements on Design
Consultants and Subcontractors to pay those parties with whom they have
contracted. Design-Builder will indemnify and defend Owner against any claims
for payment and mechanic's liens as set forth in Section 14.3 hereof.

     10.6 RECORD KEEPING AND FINANCE CONTROLS. With respect to changes in the

of the Work due to acts, omissions, conditions, events, or circumstances beyond
its control and due to no fault of its own or those for whom Design-Builder is

obligations under the Contract Documents because of a Force Majeure Event, such
party will be excused from performance affected by the Force Majeure Event to
the extent and for the period of time so affected; provided that:

          a)   the nonperforming party gives the other party notice describing
               the event or circumstance;

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

          c)   when the nonperforming party is able to resume performance of its
               obligations under the Contract Documents, that party shall give
               the other party written notice to that effect; and

          d)   in addition to Design-Builder's right to a time extension for
               those events set forth in Section 12.1 above, Design-Builder
               shall also be entitled to an appropriate adjustment of the
               Contract Price provided, however, that the Contract Price shall
               not be adjusted for those events set forth in Section 12.1 above
               that are beyond the control of both Design-Builder and Owner.

of this Agreement signed by Owner and Design-Builder, stating their agreement
upon all of the following:

               a)   The scope of the change in the Work;

               b)   The amount of the adjustment to the Contract Price; and

               c)   The extent of the adjustment to the Contract Time(s).

          13.1.2 All changes in the Work authorized by an applicable Change
Order shall be performed under the applicable conditions of the Contract
Documents. Owner and Design-Builder shall negotiate in good faith and as
expeditiously as possible the appropriate adjustments for such changes.

Design-Builder is entitled to be paid for any services required by Owner, or if
there are any other disagreements over the scope of Work or proposed changes to
the Work, Owner and Design-Builder shall resolve the disagreement pursuant to
Article 19 hereof. As part of the negotiation process, Design-Builder shall
furnish Owner with a good faith estimate of the costs to perform the disputed
services in accordance with Owner's interpretations. If the parties are unable
to agree and Owner expects Design-Builder to perform the services in accordance
with Owner's interpretations, Design-Builder shall proceed to perform the
disputed services, conditioned upon Owner issuing a written order to
Design-Builder (i) directing Design-Builder to proceed, and (ii) specifying
Owner's interpretation of the services that are to be performed. If this occurs,
Design-Builder shall be entitled to submit in its Applications for Payment an
amount equal to fifty percent (50%) of its reasonable estimated direct cost to
perform the services, and Owner agrees to pay such amounts, with the express
understanding that (x) such payment by Owner does not prejudice Owner's right to
argue that it has no responsibility to pay for such services, and (y) receipt of
such payment by


                                       23

the disputed services if Owner's order is deemed to be a change to the Work.

     13.3 EMERGENCIES. In any emergency affecting the safety of persons and/or
property, Design-Builder shall act, at its discretion, to prevent threatened
damage, injury or loss and shall notify the Owner as soon as practicable. Any
change in the Contract Price and/or the Contract Time(s) on account of emergency
work shall be determined as provided in this Article 13.

or Owner believes that it is entitled to relief against the other for any event
arising out of or related to the Work or Project, such party shall provide
written notice to the other party of the basis for its claim for relief. Such
notice shall, if possible, be made prior to incurring any cost or expense and in
accordance with the notice requirements contained Section 20.7. In the absence
of any specific notice requirement, written notice shall be given within a
reasonable time, not to exceed twenty-one (21) days, after the occurrence giving
rise to the claim for relief or after the claiming party reasonably should have
recognized the event or condition giving rise to the request, whichever is
later. Such notice shall include sufficient information to advise the other
party of the circumstances giving rise to the claim for relief, the specific
contractual adjustment or relief requested and the basis of such request.

     13.5 CONTRACT TIME ADJUSTMENT. Design-Builder shall be entitled to an
extension of the Scheduled Substantial Completion Date or Final Completion Date
to the extent the Plant is unable to operate as expected not due to any act or
omission of the Design-Builder, in addition to time extensions available due to
an event as described in Section 12.1.

the sole agreement between the parties relating to liability for infringement of
violation of any patent or copyright.

          15.2.2 Upon the occurrence of an event set forth in Section 15.2.1
above, Owner may provide written notice to Design-Builder that it intends to
terminate the Agreement unless the problem cited is cured, or commenced to be
cured, within seven (7) days of Design-Builder's receipt of such notice. If
Design-Builder fails to cure, or reasonably commence to cure, such problem, then
Owner may give a second written notice to Design-Builder of its intent to
terminate within an additional seven (7) day period. If Design-Builder, within
such second seven (7) day period, fails to cure, or reasonably commence to cure,
such problem, then Owner may

declare the Agreement terminated for default by providing written notice to
Design-Builder of such declaration.

          15.2.3 Upon declaring the Agreement terminated pursuant to Section
15.2.2 above, Owner may enter upon the premises and take possession, for the
purpose of completing the Work, of all materials, equipment, scaffolds, tools,
appliances and other items thereon, which have been purchased for the
performance of the Work, all of which Design-Builder hereby transfers, assigns
and sets over to Owner for such purpose, and to employ any person or persons to
complete the Work and provide all of the required labor, services, materials,
equipment and other items. In the event of such termination, Design-Builder
shall not be entitled to receive any further payments under the Contract
Documents until the Work shall be finally completed in accordance with the
Contract Documents. At such time, if the unpaid balance of the Contract Price
exceeds the cost and expense incurred by Owner in completing the Work, such
excess shall be paid by Owner to Design-Builder. If Owner's cost and expense of
completing the Work exceeds the unpaid balance of the Contract Price, then
Design-Builder shall be obligated to pay the difference to Owner. Such costs and
expense shall include not only the cost of completing the Work, but also losses,
damages, costs and expenses, including attorneys' fees and expenses, incurred by
Owner in connection with the re-procurement and defense of claims arising from
Design-Builder's default, subject to the waiver of consequential damages set
forth in Section 19.4 hereof.

          15.2.4 If Owner improperly terminates the Agreement for cause, the
termination for cause will be converted to a termination for convenience in
accordance with the provisions of Section 153.

     15.3 OWNER'S RIGHT TO TERMINATE FOR CONVENIENCE.

          15.3.1 Upon ten (10) days' written notice to Design-Builder, Owner
may, for its convenience and without cause, elect to terminate this Agreement.
In such event, Owner shall pay Design-Builder for the following:

          a)   To the extent not already paid, all Work executed, and for proven
               loss, cost or expense in connection with the Work;

          b)   The reasonable costs and expenses attributable to such
               termination, including demobilization costs and amounts due in
               settlement of terminated contracts with Subcontractors and Design
               Consultants;;

          c)   Overhead and profit margin in the amount of fifteen percent (15%)
               on the sum of items (a) and (b) above, except that overhead
               and profit shall not be due regarding amounts due in settlement
               of terminated contracts with subcontractors and design
               consultants; and

          d)   all retainage withheld by Owner on account of Work that has been
               completed in accordance with the Contract Documents.

employees, agents or third parties, Owner's rights to use the Work Product shall
be as set forth in Section 5.3.

     15.4 DESIGN-BUILDER'S RIGHT TO STOP WORK.

          15.4.1 Design-Builder may, in addition to any other rights afforded
under the Contract Documents or at law, stop work for the following reasons:

               a) Owner's failure to provide financial assurances as required
     under Section 4.3: or

               b) Owner's failure to pay amounts properly due under
     Design-Builder's Application for Payment.

          15.4.2 If any of the events set forth in Section 15.4.1 above occur
Design-Builder has the right to stop work by providing written notice to Owner
that Design-Builder will stop work unless such event is cured within seven (7)
days from Owner's receipt of Design-Builder's notice. If Owner fails to cure or
reasonably commence to cure, such problem, then Design-Builder may give a second
written notice to Owner of its intent to stop work within an additional seven
(7) day period. If Owner, within such second seven (7) day period, fails to
cure, or reasonably commence to cure, such problem, then Design-Builder may stop
work. In such case, Design-Builder shall be entitled to make a claim for
adjustment to the Contract Price and Contract Time(s) to the extent it has been
adversely impacted by such stoppage.

     15.5 DESIGN-BUILDER'S RIGHT TO TERMINATE FOR CAUSE.

          15.5.1 Design-Builder, in addition to any other rights and remedies
provided in the Contract Documents or by law, may terminate the Agreement for
cause for the following reasons:

               a) The Work has been stopped for sixty (60) consecutive days, or
     more than ninety (90) days during the duration of the Project, because of
     court order, any government authority having jurisdiction over the Work, or
     orders by Owner under Section 15.1 hereof, provided that such stoppages are
     not due to the acts or omissions of Design-Builder or anyone for whose acts
     Design-Builder may be responsible.

               b) Owner's failure to provide Design-Builder with any
     information, permits or approvals that are Owner's responsibility under the
     Contract Documents which result in the Work being stopped for sixty (60)
     consecutive days, or more than ninety (90) days during the duration of the
     Project, even though Owner has not ordered Design-Builder in writing to
     stop and suspend the Work pursuant to Section 15.1 hereof.

               c) Owner fails to make available to Design-Builder the Plant as
     required in Exhibit C which result in the Work being stopped for sixty
     (60) consecutive days, or more than ninety (90) days during the duration of
     the Project even though Owner


                                       28

<PAGE>

     has not ordered Design-Builder in writing to stop and suspend the Work
     pursuant to Section 15.1 hereof.

               d) Owner's failure to cure the problems set forth in Section
     15.4.1 above after Design-Builder has stopped the Work.

          15.5.2 Upon the occurrence of an event set forth in Section 15.5.1
above, Design-Builder may elect to terminate this Agreement by providing written
notice to Owner that it intends to terminate the Agreement unless the problem
cited is cured, or commenced to be cured, within seven (7) days of Owner's
receipt of such notice. If Owner fails to cure, or reasonably commence to cure,
such problem, then Design-Builder may give a second written notice to Owner of
its intent to terminate within an additional seven (7) day period. If Owner,
within such second seven (7) day period, fails to cure, or reasonably commence
to cure, such problem, then Design-Builder may declare the Agreement terminated
for default by providing written notice to Owner of such declaration. In such
case, Design-Builder shall be entitled to recover in the same manner as if Owner
had terminated the Agreement for its convenience under Section 15.3.

     15.6 BANKRUPTCY OF OWNER OR DESIGN-BUILDER.

          15.6.1 If either Owner or Design-Builder institutes or has instituted
against it a case under the United States Bankruptcy Code (such party being
referred to as the "Bankrupt Party"), such event may impair or frustrate the
Bankrupt Party's ability to perform its obligations under the Contract
Documents. Accordingly, should such event occur:

               a) The Bankrupt Party, its trustee or other successor, shall
     furnish, upon request of the non-Bankrupt Party, adequate assurance of the
     ability of the Bankrupt Party to perform all future material obligations
     under the Contract Documents, which assurances shall be provided within ten
     (10) days after receiving notice of the request; and

               b) The Bankrupt Party shall file an appropriate action within the
     bankruptcy court to seek assumption or rejection of the Agreement within
     sixty (60) days of the institution of the bankruptcy filing and shall
     diligently prosecute such action.

          15.6.2 If the Bankrupt Party fails to comply with its foregoing
obligations, the non-Bankrupt Party shall be entitled to request the bankruptcy
court to reject the Agreement, declare the Agreement terminated and pursue any
other recourse available to the non-Bankrupt Party under this Article 15.

          15.6.3 The rights and remedies under this Section 15.6 above shall not
be deemed to limit the ability of the non-Bankrupt Party to seek any other
rights and remedies provided by the Contract Documents or by law, including its
ability to seek relief from any automatic stays under the United States
Bankruptcy Code or the right of Design-Builder to stop Work under any applicable
provision of this Agreement.

     19.1 DISPUTE AVOIDANCE AND MEDIATION. The parties are fully committed to
working with each other throughout the Project and agree to communicate
regularly with each other at all times so as to avoid or minimize disputes or
disagreements. If disputes or disagreements do arise, Design-Builder and Owner
each commit to resolving such disputes or disagreements in an amicable,
professional and expeditious manner so as to avoid unnecessary losses, delays
and disruptions to the Work.

Design-Builder and Owner will first attempt to resolve disputes or disagreements
at the field level through discussions between Design-Builder's Representative
and Owner's Representative.

If a dispute or disagreement cannot be resolved through Design-Builder's
Representative and Owner's Representative, Design-Builder's Senior
Representative and Owner's Senior Representative, upon the request of either
party, shall meet as soon as conveniently possible, but in no case later than
thirty (30) days after such a request is made, to attempt to resolve such
dispute or disagreement. Prior to any meetings between the Senior

disagreement cannot be resolved on terms satisfactory to both parties, the
parties shall submit the dispute or disagreement to non-binding mediation. The
mediation shall be conducted by a mutually agreeable impartial mediator, or if
the parties cannot so agree, a mediator designated by the American Arbitration

including but not limited to, losses of use, profits, business, reputation or
financing, except Design-Builder does not waive any such damages resulting from
or arising out of any breach of Owner's duties and obligations under the limited
license granted by Design-Builder to Owner pursuant to Article 5.

                                   ARTICLE 20

     20.1 ASSIGNMENT. Neither Design-Builder nor Owner shall, without the
written consent of the other, which shall not be unreasonably withheld or
delayed, assign, transfer or sublet any portion or part of the Work or the
obligations required by the Contract Documents. Notwithstanding the foregoing,
Owner may, assign all of its rights and obligations under the Contract Documents
to its Lenders or Lenders' Agent as collateral security in connection with Owner
obtaining or arranging any financing for the Plant; provided, however, Owner
shall deliver, at least ten (10) days prior to any such assignment, to
Design-Builder (a) written notice of such assignment and (b) a written
instrument of assignment from the assignee in form and substance reasonably
acceptable to Design-Builder. In respect to any assignment to the Lenders or
Lenders' Agent, the written assignment may authorize such Lenders or Lenders'
Agent, to subsequently assign their rights under the Contract Documents in
connection with any foreclosure or other enforcement of their security interest,
if such Lenders or Lenders' Agent comply with clauses (a) and (b) above with
respect to such subsequent assignment. Design-Builder shall execute, if
requested, a consent to assignment for the benefit of the Lenders and/or the
Lenders' Agent, with respect to any such assignments.

Contract Documents are binding upon the parties, their employees, agents, heirs,
successors and assigns.

     20.3 GOVERNING LAW. The Agreement and all Contract Documents shall be
governed by the laws of Minnesota, without giving effect to its conflict of law
principles.

     20.4 SEVERABILITY. If any provision or any part of a provision of the
Contract Documents shall be finally determined to be superseded, invalid,
illegal, or otherwise unenforceable pursuant to any applicable Legal
Requirements, such determination shall not impair or otherwise affect the
validity, legality, or enforceability of the remaining provision or parts of the
provision of the Contract Documents, which shall remain in full force and effect
as if the unenforceable provision or part were deleted.

     20.5 NO WAIVER. The failure of either Design-Builder or Owner to insist, in
any one or more instances, on the performance of any of the obligations required
by the other under the Contract Documents shall not be construed as a waiver or
relinquishment of such obligation or right with respect to future performance.

     20.8 NO PRIVITY WITH DESIGN CONSULTANT/SUBCONTRACTORS. Nothing in the
Contract Documents is intended or deemed to create any legal or contractual
relationship between Owner and any Design Consultant or Subcontractor.

     20.9 AMENDMENTS. The Contract Documents may not be changed, altered, or
amended in any way except in writing signed by a duly authorized representative
of each party.

     20.10 COOPERATION WITH LENDERS AND INDEPENDENT ENGINEER.

          20.10.1 In connection with any financing of the Project,
Design-Builder, at Owner's cost, shall, it so requested by Owner: (1) deliver to
the Lenders or the agent acting on behalf of the Lenders ("Lenders' Agent")
certified copies of its corporate charter and bylaws, resolutions, incumbency
certificates, and/or legal opinions (covering such items as the validity and
enforceability of the Contract Documents and the due organization and existence
of Design-Builder).

          20.10.2 Design-Builder agrees that upon written notice that Owner has
assigned its rights under the Contract Documents to Lenders' Agent as security
for its obligations to Lenders: Design-Builder shall deliver to Lenders' Agent
notices given under the Contract Documents to Owner at the same time and in the
same manner as given to Owner; Lenders' Agent shall be entitled to exercise
rights and to cure any defaults of Owner under the Contract Documents and
Design-Builder shall accept such exercise or cure as though it had been done by
Owner; and Design-Builder shall execute such further agreements or documents
reasonably requested by Lenders' Agent providing assurances and other
protections to Lenders in furtherance of the provisions set forth above in
connection with the financing of the Work. Design-Builder further agrees that if
Lenders succeed to the interests of Owner in foreclosure or otherwise, Design-
Builder shall continue to perform in a timely manner its obligations under the
Contract Documents and shall recognize Lenders or any substitute entity with
proven sufficient financial and other resources to perform Owner's obligations
hereunder nominated by Lenders, and accepted by Design-Builder, in the place of
Owner.

          20.10.3 Design-Builder and Owner acknowledge that the Lenders, as a
condition to providing financing for the Plant, shall require Owner to provide
the Independent Engineer with certain participation and review rights with
respect to Design-Builder's performance of the Work. Design-Builder acknowledges
and agrees that such participation and review rights shall consist of the right
to (i) enter the Site and inspect the Work upon reasonable notice to
Design-Builder; (ii) attend all start-up and testing procedures; and (iii)
review and approve such other items for which Owner is required by Lenders to
obtain the concurrence, opinion or a certificate of the Independent Engineer or
the Lenders pursuant to the Financing Documents which items do not materially
alter the rights or impose additional obligations on Design-Builder
(collectively, the "Oversight Items").

          20.10.4 Notwithstanding anything to the contrary contained in Section
20.10.3, all the rights of the Independent Engineer with respect to the
Oversight Items derive from the corresponding rights of Owner under the Contract
Documents, and as such, neither increase Owner's rights hereunder nor increase
Design-Builder's obligations hereunder. The exercise of any


                                       38

<PAGE>

such rights by Independent Engineer shall be completed within the same time
periods as are set forth in the Contract Documents for the exercise of the
corresponding rights by Owner and Owner shall be solely responsible for
obtaining any review, inspection or approval from Independent Engineer as
required by Lenders. Should Owner fail to provide any required response to
Design-Builder within the time periods set forth in the Contract Documents due
to the action or inaction of the Independent Engineer, such failure shall have
the same effect under the Contract Documents as if such failure had been caused
by the action or inaction of Owner.

          20.10.5 For purposes hereof, Design-Builder may rely solely upon Owner
and shall have no duty to inquire as to whether or not the Independent Engineer
has exercised its rights with respect to the Oversight Items or has provided
Owner with any approval Owner may be required by Lenders to obtain from the
Independent Engineer. Any right that the Independent Engineer has failed to
exercise will be deemed waived.

                                    EXHIBIT B

GENERAL PROJECT SCOPE

Construct a 50 million-gallon per year (MGY) coal-fired ethanol plant near
Richardton, North Dakota. The plant will grind approximately 17.9 million
bushels per year to produce approximately 50 MGY of fuel grade ethanol denatured
with five percent gasoline. The plant will also produce approximately 160,750
tons per year of 11% moisture dried distillers grains with solubles (DDGS), and
approximately 151,250 tons per year of raw carbon dioxide (CO(2)) gas.

Delivered corn will be dumped in the receiving building. The receiving building
will have one truck and one rail receiving bay. The rail receiving bay will be
serviced by both a 40,000 bushel/hour leg system and a 20,000 bushel/hour
back-up leg system. The 20,000 bushel/hour leg system will also service the
truck receiving bay, giving the plant the ability to unload unit trains of corn
in the rail bay and simultaneously unloading truck quantities of corn in the
truck bay. Said receiving building shall have sufficient height to accommodate
end-dump trailers. The truck driver will drive onto one of the two 115 foot long
scales located near the administration building, be weighed and sampled, then
drive to the receiving building, dump the grain, then proceed back to the scale
and obtain a final weight ticket from the scale operator. The trucks will not be
required to move during the unloading process in the receiving building. Maximum
truck dump time is ten minutes. The two independent legs will lift the corn to
one of two 750,000 - bushel concrete storage bins or corn day bin with adequate
clean out access or sweep auger. A dust collection system will be installed on
the grain receiving system to limit particulate emissions as described in the
Air Quality Permit application.

Ground corn will be mixed in a slurry tank, routed through a pressure vessel and
steam flashed off in a flash vessel. Cooked mash will continue through
liquefaction tanks and into one of the fermenters. Simultaneously, propagated
yeast will be added to the mash as the fermenter is filling. After batch
fermentation is complete, the beer will be pumped to the beer well and then to
the beer column to vaporize the alcohol from the mash.

Alcohol streams are purified in the rectifier column and the side stripper, and
dehydrated in the molecular sieve system. Two hundred proof alcohol is pumped to
the tank farm day tank and blended with five percent natural gasoline as the
product is being pumped into one of two 750,000 gallon final storage tanks.
Loading facilities for truck and rail cars will be provided. Tank farm tanks
include: one tank for 190 proof storage, one tank for 200 proof storage, one
tank for denaturant storage and two 750,000 gallon tanks for denatured ethanol
storage.

Corn mash from the beer column is dewatered in the centrifuge(s). The centrifuge
capacity shall allow for 100% name plate production with one centrifuge out for
maintenance. The solids, called wet cake are conveyed to the dryer system. The
liquid, called thin stillage is routed to the evaporators where moisture is
removed. The wet cake and syrup are routed to the drying system. The drying
system will consist of three steam tube dryers. The exhaust from the drying
system will be routed as combustion air to the coal combustor.

A modified wel or wet cake pad is located along side the DDGS dryer building to
divert modified wet or wet cake to the pad when necessary such as start up or
for limited production of modified wet or wet cake for sales. DDGS is
pneumatically conveyed to flat storage in the DDGS storage building. Shipping is
accomplished by scooping and pushing the product with a


                                       B-1

<PAGE>

front-end loader into an in-floor conveyor system. The DDGS load out pit has
capacity for approximately one semi-trailer load. DDGS is weighed with a bulk
weigh system.

Steam will be generated in a waste heat boiler driven by the flue gases from the
coal combustor. Since the dryer exhaust is routed to the coal combustor for
combustion air, the coal combustor destroys VOCs and acts like a Thermal
Oxidizer. The combustion air is routed in such fashion that it also fluidizes a
sand bed in which the coal is introduced to combust. The combustor requires
natural gas or propane for start up. To achieve emission constraints, limestone
will be metered in with the coal to react with sulfur. The layout of the
combustor, boiler, and economizer are intended to provide drop out points for
fly ash. The final item in the layout before the induced draft fan is a dust
collector. All ash exiting the system will exit as fly ash. Both fly ash and
limestone silos are included. The fly ash and limestone silos have nominal
storage capacities of seven days.

Coal, received by truck delivery, will be stored in two silos with a combined
storage capacity of approximately five days. At the outlet of each coal silo,
coal will be sized (3/4" minus) and limestone added before being routed to the
coal feeder bunkers. The coal combustor will also utilize anhydrous ammonia for
NOx emission reduction. A CEMS (Continuous emission monitoring system) is
included, sufficient to meet the monitoring requirements of the air permit

Fresh water for the boilers, cooking, cooling tower and other processes will be
obtained from the Owner supplied water pretreatment system. Boiler water
conditioned in regenerative softeners will be pumped through a deaerator
scrubber and into a deaerator tank. Appropriate boiler chemicals will be added
as preheated water is sent to the boiler.

The process will be cooled by circulating water through heat exchangers and a
cooling tower. No chiller is included and Owner assumes sole and complete
responsibility for any production capacity shortfalls or other limitations or
efficiency loss related to the elimination of the chiller from the design.

The design includes a compressed air system consisting of air compressor(s), a
receiver tank, pre-filter, coalescing filter, and double air dryer(s).

The design also incorporates the use of a clean-in-place (CIP) system for
cleaning cook, fermentation, distillation, evaporation, centrifuges, and other
systems. Fifty percent caustic soda is received by truck and stored in a tank.

Under normal operating circumstances, the plant will not have any wastewater
discharges that have been in contact with com, corn mash, cleaning system, or
contact process water. An ICM/Phoenix Bio-Methanator will reduce the BOD in
process water allowing complete reuse within the plant. The plant will have
blowdown discharges from the cooling tower and may have water discharge from any
water pre-treatment processes. Owner shall provide on-site connection to
sanitary sewer or septic system.

Most plant processes are computer controlled by a Siemens/Moore APACS
distributed control system with graphical user interface and three workstations.
The process control room control console will have dual monitors to facilitate
operator interface between two graphics screens at the same time. Additional
programmable logic controllers (PLCs) will control certain process equipment.
Design Builder provides lab equipment.

The cooking system requires the use of anhydrous ammonia, and other systems
require the use of sulfuric acid. Therefore, a storage tank for ammonia and a
storage tank for acid will be on site to


                                      B-2

<PAGE>

provide the quantities necessary. The ammonia storage requires that plant
management implement and enforce a Process Safety Management (PSM) program. The
plant design may require additional programs to ensure safety and to satisfy
regulatory authorities.

NOTE: Exhibit B is a general description of the plant's basic operation. Not all
equipment and equipment sizes quoted may be used on every plant. Site specific
equipment and equipment sizes will be determined during each plant's final
design.

                                    EXHIBIT C

OWNER'S RESPONSIBILITIES

The Owner shall perform and provide the permits, authorizations, services and
construction as specifically described hereafter:

1)   LAND AND GRADING -- Owner shall provide a site near or in Richardton, North
     Dakota. Owner shall obtain all legal authority to use the site for its
     intended purpose and perform technical due diligence to allow
     Design-Builder to perform including, but not limited to, proper zoning
     approvals, building permits, elevation restrictions, soil tests, and water
     tests. The site shall be rough graded per Design-Builder specifications and
     be +/- three inches of final grade including the rough grading for Site
     roadways. The site soils shall be modified as required to provide a minimum
     allowable soil bearing pressure as described in Table 1.

     Other items to be provided by the Owner include, but are not limited to,
     the following: initial site survey (boundary and topographic) as required
     by the Design-Builder, layout of the property corners including two
     construction benchmarks, Soil Borings and subsequent Geotechnical Report
     describing recommendation for Roads, foundations and if required, soil
     stabilization/remediation, land disturbance permit, erosion control permit,
     site grading as described above with minimum soil standards, placement of
     erosion control measures, plant access road from a county, state or federal
     road designed to meet local county road standards, plant storm and sanitary
     sewers, fire water system with hydrants and plant water main branches taken
     from the system to be within five feet of the designated building
     locations, all tanks, motors and other equipment associated with or
     necessary to operate the fire water loop and associated systems, plant
     roads as specified and designed for the permanent elevations and effective
     depth, "construction" grading plan as drawn (including site retention
     pond), plant water well and associated permit(s). Owner shall also provide
     the final grading, seeding, and mulching, and the site fencing at the site.

     Owner is encouraged to obtain preliminary designs/information and estimates
     of the cost of performing all Owner required permits and services as stated
     in this Exhibit C. Specifically, the cost of the fire water systems
     (including associated fire water pumps, required tank, building (if
     required), sprinklers, and all other equipment and materials associated
     with the fire water delivery systems) is estimated being in excess of
     $800,000. The requirements of each state and the decisions of each Owner
     will increase or decrease the actual cost.

     The Owner's required activities related to site preparation for
     construction are to be divided into Phase I and Phase II activities as
     described below:

set forth herein;

     NOW, THEREFORE, the parties, in consideration of the foregoing premises and
the mutual promises contained herein and for other good and valuable
consideration, receipt of which is hereby acknowledged, agree as follows:

     1. Upon OWNER's payment in full of all amounts due and owing to Fagen under
     the Contract, ICM agrees to grant to OWNER a limited license to use the
     Proprietary Property (hereinafter defined) solely in connection with the

<PAGE>

     consultants or other representatives (hereinafter collectively referred to
     as "Representatives"). Information and materials shall not be deemed to be
     in the public domain merely because such information is embraced by more
     general disclosures in the public domain, and any combination of features
     shall not be deemed to be within the foregoing exceptions merely because
     individual features are in the public domain if the combination itself and
     its principles of operation are not in the public domain.

     3. OWNER shall not use the Proprietary Property for any purpose other than
     the Purpose. OWNER shall not use the Proprietary Property in connection
     with any expansion or enlargement of the Plant.

     4. OWNER's failure to materially comply with the Operating Procedures shall
     void all guarantees, representations and warranties, whether expressed or
     implied, if any, that were given by ICM to OWNER, directly or indirectly
     through Fagen, concerning the performance of the Plant. OWNER agrees to
     indemnify, defend and hold harmless ICM, Fagen and their respective
     Representatives from any and all losses, damages and expenses including,
     without limitation, reasonable attorneys' fees resulting from, relating to
     or arising out of Owner's or its Representatives' (i) failure to materially
     comply with the Operating Procedures or, (ii) negligent or unauthorized use
     of the Proprietary Property.

     5. Any and all modifications to the Proprietary Property by OWNER or its
     Representatives shall be the property of ICM. OWNER shall promptly notify
     ICM of any such modification and OWNER agrees to assign all of its right,
     title and interest in such modification to ICM; provided, however, OWNER
     shall retain the right, at no cost, to use such modification in connection
     with the Purpose.

     6. ICM has the exclusive right and interest in and to the Proprietary
     Property and the goodwill associated therewith. OWNER will not, directly or
     indirectly, contest ICM's ownership of the Proprietary Property. OWNER'S
     use of the Proprietary Property does not give OWNER any ownership interest
     or other interest in or to the Proprietary Property except for the limited
     license granted to OWNER herein.

     7. OWNER shall pay no license fee or royalty to ICM for OWNER'S use of the
     Proprietary Property pursuant to the limited license granted to OWNER, the
     consideration for this limited license is included in the amounts payable
     by OWNER to Fagen for the construction of the Plant under the Contract.

     8. OWNER may not assign the limited license granted herein, in whole or in
     part, without the prior written consent of ICM, which will not be
     unreasonably withheld or delayed. Prior to any assignment, OWNER shall
     obtain from such assignee a written instrument, in form and substance
     reasonably acceptable to ICM, agreeing to be bound by all the terms and
     provisions of this License Agreement. Any assignment of this License
     Agreement shall not release OWNER from (i) its duties and obligations
     hereunder concerning the disclosure and use of the Proprietary Property, or
     (ii) damages to ICM resulting from, or arising out of, a breach of such
     duties or obligations by OWNER or its Representatives. ICM may assign its
     right, title and interest in the Proprietary Property, in whole or part,
     subject to the limited license granted herein.

     9. The Proprietary Property is confidential and proprietary. OWNER shall
     keep the Proprietary Property confidential and shall use all reasonable
     efforts to maintain the Proprietary Property as secret and confidential for
     the sole use of OWNER and its Representatives for the Purpose. OWNER shall
     retain all Proprietary Property at its principal place of business and/or
     the Plant. OWNER shall not at any time without ICM's prior written consent,
     copy, duplicate, record, or otherwise reproduce the Proprietary Property,
     in whole or in part, or otherwise make the same available to any
     unauthorized


                                       D-2

<PAGE>

     person. OWNER shall not disclose the Proprietary Property except to its
     Representatives who are directly involved with the Purpose, and even then
     only to such extent as is necessary and essential for such Representative's
     involvement. OWNER shall inform such Representatives of the confidential
     and proprietary nature of such information. OWNER shall make all reasonable
     efforts to safeguard the Proprietary Property from disclosure by its
     Representatives to anyone other than permitted hereby. In the event that
     OWNER or its Representatives are required by law to disclose the
     Proprietary Property. OWNER shall provide ICM with prompt written notice of
     same so that ICM may seek a protective order or other appropriate remedy.
     In the event that such protective order or other appropriate remedy is not
     obtained, OWNER or its Representatives will furnish only that portion of
     the Proprietary Property which in the reasonable opinion of its or their
     legal counsel is legally required and will exercise its reasonable efforts
     to obtain reliable assurance that the Proprietary Properly so disclosed
     will be accorded confidential treatment.

     10. OWNER agrees to indemnify ICM for any and all damages (including,
     without limitation, reasonable attorneys' fees) arising out of or resulting
     from any unauthorized disclosure or use of the Proprietary Property by
     OWNER or its Representatives. OWNER agrees that ICM would be irreparably
     damaged by reason of a violation of the provisions contained herein and
     that any remedy at law for a breach of such provisions would be inadequate.
     Therefore, ICM shall be entitled to seek injunctive or other equitable
     relief in a court of competent jurisdiction against OWNER or its
     Representatives for any unauthorized disclosure or use of the Proprietary
     Property without the necessity of proving actual monetary loss or posting
     any bond. It is expressly understood that the remedy described herein shall
     not be the exclusive remedy of ICM for any breach of such covenants, and
     ICM shall be entitled to seek such other relief or remedy, at law or in
     equity, to which it may be entitled as a consequence of any breach of such
     duties or obligations.

     11. All provisions of this License Agreement shall survive and remain in
     full force and effect notwithstanding any termination or expiration of the
     Contract or the license granted herein under paragraph 12.

     12. ICM may terminate the limited license granted to OWNER herein upon
     written notice to OWNER if OWNER willfully or wantonly uses the Proprietary
     Property for any purpose, or discloses the Proprietary Property to anyone,
     other than permitted herein. Upon termination of the license, OWNER, upon
     request by ICM, shall promptly return to ICM all documents in OWNER's or
     its Representatives' possession that contain Proprietary Property.

     13. The laws of the State of Kansas, United States of America, shall govern
     the validity of the provisions contained herein, the construction of such
     provisions, and the interpretation of the rights and duties of the parties.
     Any legal action brought to enforce or construe the provisions of this
     License Agreement shall be brought in the federal or state courts located
     in Kansas, and the parties agree to and hereby submit to the exclusive
     jurisdiction of such courts and agree that they will not invoke the
     doctrine of forum non conveniens or other similar defenses in any such
     action brought in such courts. In the event the Plant is located in, or
     OWNER is organized under the laws of, a country other than the United
     States of America, OWNER hereby specifically agrees that any injunctive or
     other equitable relief granted by a court located in the State of Kansas,
     United States of America, or any award by a court located in the State of
     Kansas, shall be specifically enforceable as a foreign judgment in the
     country in which the Plant is located, OWNER is organized or both, as the
     case may be, and agrees not to contest the validity of such relief or award
