4.      DETERMINATION OF AWARDS. The amount of the Award payable to each
        Eligible Employee for each Plan Year shall equal $500,000 for every
        $1.00 of Base Net Income Per Share for the Plan Year, or the pro-rata

        and may amend it from time to time; provided, however, that no
        termination or amendment of the Plan shall adversely affect the rights
        of an Eligible Employee or a beneficiary to a previously earned Award.

8.      GENERAL PROVISIONS.

        a.      Nothing set forth in this Plan shall prevent the Board from
                adopting other or additional compensation arrangements. Neither
                the adoption of the Plan or any Award hereunder shall confer
                upon an Eligible Employee any right to continued employment.

        b.      No member of the Board or the Committee, nor any officer or
                employee of the Company acting on behalf of the Board or the

    2006 or a review of the available subsurface information, or (2) are unknown
    physical conditions of an unusual nature, which differ materially from those
    ordinarily found to exist and generally recognized as inherent in
    construction activities of the character provided for in this Contract, or
    (3) differ from conditions shown in any drawing, document or other
    information, if any, that Owner is required to deliver to Delta-T under
    Section 3 above, then notice by the observing Party shall be given to the
    other Party promptly before such conditions are further disturbed and in no
    event later than 21 days after first observance of the conditions. If any
    such condition causes any increase or decrease in Delta-T's cost of, or time
    required for, performance of any part of the Work, or any increase or
    decrease in any other obligation of Delta-T, Owner shall within 21 days of
    issuance or receipt of notice, as the case may be, under this Section 4.1,
    issue a change order in accordance with Section 6 below.

    others, but any changes to the Work or the Schedule required to do so shall
    be treated as a change under Section 6 below. Notwithstanding the foregoing,
    Delta-T shall not be required to check the quality or quantity of work
    performed by Owner or Owner's contractors or subcontractors, provided,
    however, Delta-T shall confirm that any predecessor work shall be sufficient
    for Delta-T's Work. Delta-T shall not have control over or responsibility
    for the construction, methods, techniques, sequences or procedures, or for
    safety precautions and programs used by Owner or Owner's contractors or
    subcontractors in connection with the Work and shall have no liability
    thereon.

5.  SCHEDULE

    5.1 SCHEDULE: Delta-T shall use its best reasonable efforts to perform the
    Work in accordance with the Schedule, but it does not guarantee that the
    Work will be completed according to such Schedule. In case of any delay
    other than a delay caused by Delta-T, its employees, subcontractor's or
    vendors for reasons other than force majeure (which shall be treated in
    accordance with Section 19 below), the Schedule for completion of the Work,
    or any part of it, shall be extended by a number of days equal to the actual
    number of days of such delay, plus the number of days reasonably required
    for demobilization and remobilization. Delta-T shall use all reasonable
    efforts to comply with Owner's wishes with respect to changes in Schedule,
    but any adjustment requested by Owner to the Schedule shall be deemed a
    change and Delta-T shall have no obligation to slow down or accelerate its
    performance of the Work except in accordance with Section 6 below.

    5.2 COMPENSATION TO DELTA-T FOR DELAY: In the event of any delay caused by
    Owner, its employees, subcontractor's or vendors for reasons other than
    force majeure exceeds, individually or in the aggregate, fourteen (14) days,
    Delta-T shall be entitled to compensation for its unavoidable direct costs
    resulting from such delay, including in particular, but without limitation,
    the costs, if any, of extended site overhead and those itemized at Exhibit
    B.

6.  CHANGES

                                       10
<PAGE>

    6.1 ISSUANCE OF CHANGE ORDERS BY OWNER: Owner may by its written order
    require changes in the Work within the general scope of the Contract
    consisting of additions, deletions or other revisions which do not result in
    any material change in the Work, provided that the Contract Sum and payment
    schedule are adjusted to reflect the change in Delta-T's direct costs
    resulting from such changes, plus a reasonable amount for profit, and that
    the time allowed for completion, warranty obligations, and any other
    obligations of Delta-T affected by the changes are adjusted to cover the
    consequences to Delta-T resulting from such change. Furthermore, Owner shall
    issue a change order providing for all such adjustments when required to do
    so under Section 4.1 above. The amount to be paid to Delta-T, the effect on
    Schedule, if any, and any other adjustments to the Contract will be made by
    mutual agreement. If the change, in Delta-T's judgment, would have a
    detrimental impact on performance of the Plant, or if the amount of the cost
    of the change order in dispute exceeds 1% of the Contract Sum, then Delta-T
    shall have no obligation to proceed with any change until such agreement is
    reached. Furthermore, Delta-T shall in no case be required to agree to any
    change requiring the handling of PCBs, asbestos or any other hazardous
    material. In all other cases, if Owner and Delta-T are unable to reach
    agreement within fifteen (15) days of the date of Delta-T's notice to Owner
    provided in accordance with Section 6.2 below, then Delta-T shall proceed
    with the change and the matter shall be resolved as provided at Section 18
    below.

    6.2 NOTICE OF INSTRUCTION CONSTITUTING A CHANGE; NOTICE OF IMPACT OF CHANGE
    ORDER: If Delta-T receives instructions from Owner, which in Delta-T's
    opinion constitute a change in the Work, Delta-T shall so advise Owner
    within five (5) business days of receipt of such instruction. If Delta-T
    receives a change order under Section 6.1 above or becomes aware of a
    constructive change order of the type described at Section 6.3 below, or
    gives Owner a notice that an instruction of Owner constitutes a change, then
    Delta-T shall within ten (10) business days thereafter submit to Owner a
    statement of the impact of such change on Contract Sum, payment schedule,
    Schedule, warranties, and any other provisions of the Contract affected
    thereby. Delta-T shall not delay prosecution of the Work not affected by the
    change.

    6.3 CONSTRUCTIVE CHANGE ORDERS: Any of the following shall be deemed
    constructive change orders: (a) a modification of applicable law, ordinance
    or regulation resulting in any increase in taxes or insurance premiums, or
    any other cost, payable by Delta-T or in any government regulated costs that
    was not or should not have been reasonably anticipated by Delta-T, (b) any
    increase in Delta-T's costs due to force majeure, but only to the extent (i)
    such costs are not compensated by insurance, and (ii) the actual delay
    caused by the force majeure event is more than five (5) days, and (iii) such
    costs include the direct costs of the force majeure event plus fifty percent
    of any extended general condition costs, or (c) unknown or differing site
    conditions of the type described at Section 4.1 above.

7.  COMMISSIONING, STARTUP, TRAINING OF OWNER'S PERSONNEL, AND FINAL ACCEPTANCE

    7.1 MECHANICAL COMPLETION AND COMMISSIONING: Delta-T shall give Owner at
    least five calendar days notice when Delta-T believes that the Work has
    reached Mechanical Completion. Owner and Delta-T shall, within seven
    calendar days jointly inspect the Work and prepare a proposed Punch List.
    Such Punch List shall clearly designate which items, if any, need to be
    completed in order to reach Mechanical Completion. Delta-T shall within
    three (3) calendar days of receipt of the jointly prepared Punch List mark
    the list to show Delta-T's disagreement, if any, with any of the items
    listed by Owner, and return a copy of the list so marked and signed by
    Delta-T to Owner. In the event that Parties do not agree on the items that
    should be included on the Punch List within three (3) calendar days
    thereafter, then either Party may submit the matter to disputes resolution
    under Section 18 below. Owner and Delta-T shall commence Commissioning upon
    achievement of Mechanical Completion of the Plant.

    7.2 PERFORMANCE TEST: Owner and Delta-T shall Startup the Plant and begin
    the Performance Test as soon as the conditions to Startup described in
    Exhibit C have been completed. If for any reason the Performance Test is not
    completed on the first attempt, then Owner shall allow Delta-T reasonable
    access to the Plant to do all things required to be done to achieve Final
    Completion for a period of at least six (6) months after Startup, as
    provided at Exhibit D.

    7.3 TRAINING OF OWNER'S PERSONNEL: Delta-T shall provide the training
    described in Exhibit A. Except as provided otherwise in Exhibit A, Owner
    shall provide appropriate personnel, and Delta-T shall provide such
    training, at times mutually agreed by them, commencing prior to
    Commissioning in sufficient time to prepare Owner's employees to perform
    Commissioning and Startup and to perform their obligations with respect to
    the Performance Test.

                                       12
<PAGE>

    7.4 USE OF PLANT PRIOR TO FINAL ACCEPTANCE: Owner may use the Plant for
    commercial purposes on or after the achievement of Mechanical Completion. If
    Owner elects to use any portion of the Work for commercial purposes prior to
    Final Completion, however, then it shall allow Delta-T free access to the
    Plant to do all things required to be done to achieve Final Completion,
    including without limitation, shut downs of the Plant, as reasonably
    necessary including, without limitation, preparation for and execution of
    one or more Performance Tests.

    7.5 FAILURE TO REACH FINAL COMPLETION FOR REASONS BEYOND DELTA-T'S CONTROL:
    Subject to the provisions of Section 19 below, if for any reason Owner fails
    to permit Delta-T access to the Plant after the date of Mechanical
    Completion in order to permit Delta-T to do all things necessary to achieve
    Final Completion, or Delta-T is prevented from achieving Final Completion
    for reasons beyond Delta-T's control and such failure to permit access or
    prevention of performance continues for an aggregate of sixty (60) days,
    then Final Completion shall be deemed to occur on the sixtieth day (in the
    aggregate) that such access is denied or performance prevented for purposes
    of payment only in accordance with Section 8 below. Delta-T shall complete
    the Performance Testing in accordance with Exhibit C.

8.  PAYMENT

    8.1 CONTRACT SUM: Owner will pay Delta-T for the full and satisfactory
    completion of the Work the Contract Sum of $61,800,000.00, or such other sum
    as may be determined in accordance with Section 6. In addition to the sum of
    $61,800,000.00, Owner will pay Delta-T the sum of $10,600,000.00 for the
    cost of the dryer, field-fab tanks, shop-fab tanks, bulk piping and
    electrical wiring[.] * * The Contract Sum does not include any sales or
    other tax. If Delta-T is, now or in the future, required to collect from
    Owner or pay any federal, state, local or other tax with respect to all or
    any part of the Work, then that amount shall be paid by Owner at Delta-T's
    request, in addition to the Contract sum. The Contract Sum listed in this
    paragraph 8.1 is contingent on

    * PORTIONS OMITTED PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT WHICH
    HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

                                       13
<PAGE>

    the Owner making the first payment to Delta-T in the amount of $8,000,000.00
    (equipment deposits) on or before August 9, 2006. In the event that the
    Owner fails to make this payment, a constructive change order shall be
    issued to cover any increase in equipment costs.

    8.2 PAYMENT TERMS: Owner shall make payment in accordance with Exhibit B and
    this Section 8. Delta-T shall submit Applications for Payment in the form
    set forth at Exhibit B. Owner shall, through Owner's Representative, sign
    the Certificate for Payment set forth on the Application for Payment for the
    full payment applied for, unless it believes that all or any part of such
    amount is not then due. If Owner believes all or part of the amount
    requested in the Application for Payment is not then due, Owner shall amend
    the Certificate for Payment contained therein by indicating the amount, if
    any, that it believes to be due, and shall sign the certificate as amended
    and deliver the certificate, together with written notice of Owner's reasons
    for certifying less than the whole amount of applied for. Owner or Owner's
    construction lender shall wire transfer, in immediately available funds, all
    amounts for which it has issued certificates, within the time set forth in
    Exhibit B, and if no time is indicated thereon, within thirty (30) days of
    the date of its receipt of the Application for Payment, to a bank account to
    be selected by Delta-T, at its sole discretion. Owner's payment shall
    constitute a Certificate for Payment if the Certificate for Payment form is
    not executed by Owner. If Owner does not certify payment in the amount of
    the Application, and Delta-T and Owner cannot agree on a revised amount
    within fifteen (15) days of the date of the Certificate for Payment for less
    than the full amount, then either Party may request a demand for arbitration
    in accordance with Section 18. In any case, when the reasons stated by Owner
    for withholding payment of any amount for which an application has been made
    are removed, in whole or in part, Owner shall immediately issue a
    Certificate for Payment for the amount withheld and make payment, via wire
    transfer as described in this Section 8.2, of the amount so certified. .

    8.3 LATE PAYMENT: Owner shall pay the lesser of 1.0% per month or the
    highest amount permitted by law on all sums more than 10 calendar days past

    all valid amounts due for all materials, labor and equipment used in or in
    connection with the performance of this Contract, including those of its
    subcontractor's and vendors, when bills or claims become due, and shall
    indemnify and hold harmless Owner from and against all claims of its
    subcontractors and vendors for amounts due arising from Delta-T's failure to
    make any such payments, provided that Owner gives Delta-T prompt notice of
    such claim and cooperates with Delta-T in defense of such claim.

                                       14
<PAGE>

    8.5 MECHANIC'S LIENS: Delta-T shall keep the real property upon which the
    Plant is to be located free and clear of laborer's, materialmen's and
    mechanic's liens arising out of the performance of the Work for which Owner
    has made payment. Owner shall promptly notify Delta-T in writing of any lien
    so arising of which it has notice or knowledge. Delta-T shall obtain and
    timely provide to Owner a partial release of lien with respect to any
    partial or progress payment made to relevant subcontractors and shall also
    obtain and timely provide a complete release of lien and general release
    with respect to any subcontract for which full and final payment is made. In
    each case, the release of lien may be for an amount less amounts that will
    be paid from the payment for which such release of lien is requested.
    Delta-T shall promptly pay each subcontractor upon receipt of payment from
    Owner of the amount invoiced that is due to such subcontractor.

    8.6 FINAL PAYMENT: Delta-T shall invoice Owner for the final amount due to
    it in accordance with Exhibit B.

    8.7 CONSTRUCTION LENDER. Delta-T understands that Owner is obtaining

    making progress and other payments to Delta-T. Delta-T agrees to cooperate
    with any and all reasonable requirements and procedures imposed by Owner's
    construction lender.

    8.8 WITHHOLDING PAYMENTS. Owner shall be entitled to deduct from any amounts
    due or owing by Owner to Contractor any amounts as may be reasonably
    necessary to protect owner from losses due to:

    (a) Work that is damaged, defective or not in conformance with this
    Agreement and has not been remedied by Contractor after having written
    notice from Owner of such damage, defect or nonconformity and Contractor
    having not corrected such damage, defect or nonconformity within thirty (30)
    calendar days of receiving such notice; or

                                       15
<PAGE>

    (b) Failure of Contractor to pay Subcontractors, or for labor, materials or
    Equipment unless a Payment Default has occurred and is continuing and then
    only to the extent such Work was part of the Invoice which forms the basis
    of the Default Payment; or

    (c) claims filed by third parties relating to or arising out of the Work
    against the Owner or its Construction Lender and damage to the Owner or
    another person or entity caused by Delta-T, its subcontractor, or material
    suppliers that arise out of the Work, provided such claim or damage has not
    been resolved by Delta-T after having written notice from Owner of such
    claim or damage and Delta-T not having corrected or resolved such claim or
    damage within thirty (30) days of receiving such notice.

9. RIGHTS OF OWNER AND DELTA-T TO SUSPEND WORK OR TERMINATE

    9.1 OWNER'S RIGHT TO TERMINATE FOR CAUSE: Owner may terminate this Contract
        if: a. a petition in bankruptcy is filed by Delta-T, and such filing
        materially impacts Delta-T's ability to perform its obligations under
        this Contract, or such a petition is filed against Delta-T and it is not
        dismissed within 45 days, or

        b. Delta-T commits a material breach of a material obligation under this
        Contract, or fails to make reasonable progress toward completion of the
        Work, and fails to cure such breach or failure within the longer of 45
        days of its receipt of written notice of such breach or such longer time
        as is reasonably required to cure such breach.

    Upon such termination Owner may take possession of the Work completed by
    Delta-T or delivered to the Plant site and all materials and Equipment at
    the site acquired for incorporation into the Work and owned by Owner or
    Delta-T, take assignment of all purchase orders and subcontracts related to
    the Work and complete the Work by whatever reasonable method Owner may deem
    expedient. Owner shall permit Delta-T access to the Plant site after such
    termination as reasonably required by Delta-T to remove any equipment,
    trailers, supplies, goods and materials maintained by Delta-T in connection
    with the Work but not intended to be incorporated into the Plant, or owned
    or used by any of its subcontractors under subcontracts not to be assigned
    to Owner. In the event of termination for any of the reasons set forth
    above, Delta-T will be liable to Owner for any reasonable costs incurred by

                                       16
<PAGE>

    Owner to complete the Work in excess of the Contract Sum remaining unpaid to
    Delta-T, up to a maximum of 10% of the Contract Sum. In case of such
    termination, the license granted under Section 17.2 below with respect to
    the Delta-T Technology delivered prior to the date of termination shall
    become effective, no further payments will be made to Delta-T after
    termination until the Work is completed and upon completion of the Work,
    Owner shall pay Delta-T the balance due under this Contract, less the
    amounts required to be paid by Owner to third parties to complete the Work,
    and if the unpaid balance of the Contract Sum is less than the cost of
    finishing the Work, Delta-T shall then pay such excess, up to a maximum of
    the amount set forth in the preceding sentence.

    9.2 DELTA-T'S RIGHT TO STOP WORK: If Owner does not pay Delta-T amounts that
    Owner has certified for payment within five (5) Days after the date such
    payment is due, then Delta-T may, upon ten (10) Days written notice to
    Owner, stop the Work until payment of the amount owing has been received.;
    provided, however, Delta-T may not stop the Work if there is a good faith
    dispute regarding the amount of payment due Delta-T. If Delta-T suspends the
    Work under this Section 9.2, then the time allowed for completion of any of
    the Work shall be extended as provided at Section 5.1 above.

    9.3 DELTA-T'S RIGHT TO TERMINATE: Delta-T may terminate the Contract on
    seven (7) Days written notice if the Work is stopped, without fault on the
    part of the Delta-T or, any of its vendors or subcontractors, for more than
    twenty-one Days, for any of the following reasons:
          a. a petition in bankruptcy is filed by Owner, and such filing
          materially impacts Owner's ability to perform its obligations under
          this Contract, or such a petition is filed against Owner and it is not
          dismissed within forty-five (45) Days.
          b. Owner has not made payment within sixty (60) Days of the date due;
          or
          c. Owner commits any other material breach of a material obligation
          under this Contract, and fails to cure such breach within the longer
          of 45 Days of its receipt of written notice of such breach or such
          longer time as is reasonably required to cure such breach.

    Delta-T may terminate the Contract on seven (7) Days written notice if the
    Work is stopped, without fault on the part of the Delta-T or, any of its
    vendors or subcontractors, for more than ninety (90) Days because of the
    issuance of any order of a court or other public authority having
    jurisdiction over the Site or project.

                                       17
<PAGE>

    Upon such termination Owner shall pay Delta-T (a) all amounts then due to it
    under this Contract as of the date of termination, including all amounts
    completed but not yet invoiced, and including the portions, if any, of such
    amounts that would have been held as retainage in accordance with Exhibit B,
    (b) all unavoidable costs payable to subcontractors at any tier and all
    other vendors related to the work, including reasonable fees for
    cancellation, and (c) a termination fee calculated as set forth in Exhibit
    B. For this purpose, the amounts then due to Delta-T shall be deemed to be
    all amounts billed in accordance with Exhibit B up to the date of
    termination, plus the value of all goods delivered and services performed
    under this Contract and not billed as of the date of termination. In the
    event that the Parties cannot agree on the total amount due within thirty
    (30) Days of the date of Delta-T's demand for payment hereunder, either
    Party may initiate arbitration under Section 18.2 below.

10.  SAFETY AND SECURITY

    likewise. At completion of the Work, Delta-T shall leave the premises clean
    of all debris resulting from performance of the Work. Owner shall provide
    dumpsters for disposal or recycling of materials and Delta-T shall be
    responsible to insure that the proper material is placed in the appropriate
    dumpster. Owner shall receive the proceeds of the sale or recycling of any
    salvage items or scrap from the project.

    10.2 SECURITY: During construction and installation of the Work, Delta-T
    will use reasonable means to protect the Work and all Equipment and
    materials to be used in connection with the Work and located on the Work

    all equipment owned or leased by Delta-T or any of its subcontractors, and
    all other equipment and goods of any kind located at the Plant site for the
    purpose of performing the Work.

    10.3 SAFETY: Delta-T will insure all its labor and other authorized
    personnel comply with all appropriate safety and security regulations,
    procedures or standards. Delta-T shall furnish and maintain all necessary
    safety equipment and training for its employees and shall maintain a safe
    work site at all times. All Work shall be performed in accordance with
    Delta-T and its primary subcontractor's safety plan.

                                       18
<PAGE>

    10.4 COMPLIANCE WITH OSHA AND SIMILAR LAWS AND REGULATIONS: Owner shall at
    all times be solely responsible for compliance with the Occupational Safety
    and Health Act ("OSHA"), and any similar state laws or regulations, with
    respect to its own employees. In particular, but without limitation, Owner
    shall be responsible for claims made by any of its employees, by reason of
    any personal injury or death which results from a violation of any such law
    or regulation. Delta-T shall be solely responsible for compliance with OSHA,
    and any similar state laws or regulations, with respect to its own employees
    and will require the same of its subcontractors. In particular, but without
    limitation, Delta-T shall be responsible for claims made by any of its
    employees, whether against Owner or Delta-T by reason of any personal injury
    or death which results from a violation of any such law or regulation. The
    Schedule shall be extended as necessary to allow for cure of any unsafe
    condition, which results in a suspension of the Work, which is caused by
    anyone other than Delta-T, its agents, employees or sub-subcontractors.

11.  PROJECT EXECUTION

    11.1 DELTA-T REPRESENTATIVES: Delta-T will keep a Project Manager
    ("Delta-T's Project Manager") assigned to the Work at all times during its
    progress, and shall keep a Site Manager on the Work site on a daily basis
    during the construction phase of the Work. Delta-T's Project Manager shall
    represent Delta-T, and written communications given to Delta-T's Project
    Manager or Delta-T's Site Manager shall be as binding as if given to Delta-T
    itself. All communications to Delta-T's Project Manager or Site Manager by
    Owner shall be confirmed in writing upon request by Delta-T.

    11.2 OWNER REPRESENTATIVE: Owner will have at all times during the progress
    of the Work, a competent representative ("Owner's Representative") assigned
    to the Work. Owner's Representative shall represent Owner, and written
    communications given to Owner's Representative shall be as binding as if
    given to Owner itself. Owner shall have its Owner's Representative on site,

                                       19
<PAGE>

        11.3.1 REVIEWS: Delta-T will, as appropriate, and additionally upon
        Owner's request, issue a project progress schedule to Owner. Delta-T
        shall provide Owner each week a two-week look ahead schedule. Delta-T
        shall participate in weekly meetings to review the progress of the Work
        at the Work site at Owner's request as set forth in Exhibit A. . Owner
        may review and comment on any plan, drawing or specification, that
        Delta-T delivers to Owner. No review or comment made by Owner shall
        result in Owner's being deemed to have assumed any responsibility for
        any of the Work. Delta-T shall attempt to incorporate Owner's comments
        where it can do so without increasing Delta-T's cost, the time required
        for performance, or any of its other obligations, but Delta-T shall have
        no obligation to suspend work to allow time for review and comment
        except as provided in the Schedule, or to incorporate any of Owner's
        comments except as required in order to comply with Delta-T`s
        obligations under the Contract, or as agreed under Section 6 above.

        11.3.2 APPROVAL PROCESS: If Exhibit A or the Schedule provides for
        approval by Owner of any portion of the Work or any document, then Owner
        shall be deemed to have given its approval unless it delivers written
        notice of its disapproval, and the specific reasons for its disapproval
        within the time allowed according to the Exhibit or Schedule.In the
        event that the reason for disapproval by the reviewing Party results
        from failure of the other Party ("submitting Party") to fulfill any of
        its obligations under this Contract, then the submitting Party shall
        correct the work or document requiring correction and resubmit it for
        review. The reviewing Party shall have five (5) business days, or
        one-half the time allowed according to the applicable Exhibit or
        Schedule if such time is prescribed, for the initial review to approve
        or disapprove the resubmitted work or document, and it shall be deemed
        to have given its approval unless it delivers written notice of its
        disapproval, and the specific reasons for its disapproval, within that
        time. The review and resubmittal process shall continue in like manner
        until the submitted Work is approved. In the event that any disapproval
        results from a cause other than failure of the submitting Party to
        fulfill any of its obligations under this Contract, the Schedule shall
        automatically be extended as provided at Section 5.1 above.

    11.4 SUBCONTRACTORS AND VENDORS:

                                       20
<PAGE>

        11.4.1 NOTICE OF SUBCONTRACTOR SELECTION: Delta-T shall, as soon as
        practicable after award of the Contract, furnish in writing to Owner the
        names of persons or entities (including those who are to furnish
        materials or equipment fabricated to a special design) proposed for
        major portions of the Work. Owner acknowledges that Delta-T,
        particularly on large or fast-track projects, may not make final
        selection of some subcontractor or vendors until later in the project,
        and that Delta-T has the right to select subcontractors and vendors as
        long as the selection would not result in failure to satisfy the
        requirements of this Contract. The subcontracting of any portion of the
        Work, as described in Exhibit A, shall not relieve Delta-T of
        responsibility for performance of the Work as provided therein.
        Notwithstanding the foregoing, Delta-T shall have the right to
        subcontract such portions of the Work as it shall determine to be
        necessary to others which, in turn, shall have the right to subcontract
        such portions of the Work assigned to them, if any, as they shall deem
        necessary.

12.  WARRANTY

    12.1 EQUIPMENT WARRANTIES: Delta-T shall, for the protection of Owner,
    assign to Owner all warranties and guarantees supplied by all vendors and
    subcontractors from who it procured goods or services incorporated into the
    Project. In addition, Delta-T warrants to Owner that the Equipment will be
    free from mechanical defects, structural defects and defects in material and
    workmanship until twelve (12) months from completion of the Performance
    Test,. OWNER'S SOLE AND EXCLUSIVE REMEDY IN CASE OF BREACH OF THIS WARRANTY
    SHALL BE REPAIR OR REPLACEMENT AS PROVIDED IN THIS SECTION 12.1. If any
    defect covered by the above warranties is discovered within the warranty
    period, Delta-T shall, subject to the provisions set forth below, repair or
    replace the defective material or Equipment. The decision to repair or
    replace shall be made by Owner. If Owner and Delta-T do not agree on whether
    repair or replacement is the most appropriate remedy, and if the remedy
    recommended by Delta-T would not impair the performance of the Work or
    otherwise materially diminish the value of the Work, then Delta-T shall not
    be required to perform the remedy elected by Owner unless Owner pays Delta-T
    the excess cost of performing such remedy over and above the cost of
    performing the remedy recommended by Delta-T. Delta-T shall in no case have
    any liability, under this warranty or otherwise, for any defect or
    deterioration which results from failure of Owner to provide any feedstock,
    utilities, or other supplies, services or conditions specified in Exhibit C,
    force majeure, improper operation or maintenance including damage caused by
    freezing, foreign substance or impurity introduced into the equipment, or
    any other matter not within Delta-T's control.

                                       21
<PAGE>

    12.2 DESICCANT MATERIAL: Delta-T warrants that the molecular sieve desiccant
    will not deteriorate due to mechanical abrasion to such an extent as to
    reduce the dehydration capacity of the molecular sieve below the level
    specified in the Performance Guarantee set forth at Exhibit D for a period
    of five years from twelve (12) months from the completion of the Performance
    Test. OWNER'S SOLE AND EXCLUSIVE REMEDY UNDER THIS WARRANTY SHALL BE
    REPLACEMENT OF THE DESICCANT MATERIAL AS PROVIDED IN THIS SECTION 12.2.
    Replacement shall be made at no cost to Owner in the event of a claim under
    this warranty within one year after Final Acceptance. With respect to any
    claim made thereafter, the desiccant replacement cost to Owner shall be pro
    rated, on a daily basis, on the basis of the number of days remaining in the
    last four (4) years of the warranty period. As an example, Owner would pay
    50% of the cost of replacement desiccant if the original desiccant had to be
    replaced exactly three (3) years from the commencement of the warranty
    period (100% x 730th day/ 1460 total Days).

    12.3 PROFESSIONAL SERVICES: Delta-T warrants, for a period ending one year
    after Final Acceptance, or the last date on which Delta-T performed work
    under this Contract if this Contract is terminated for any reason prior to
    Final Acceptance, that the services provided by it hereunder will be
    provided with reasonable skill and care of the type normally exercised by
    other design professionals under similar circumstances. Delta-T shall not
    have any obligation or liability for failures or defects due to ordinary
    wear and tear, corrosion or erosion, or as a result of improper operation,
    improper maintenance or operating conditions more severe than, or different
    from, those contemplated in the original design of the Work.

    12.4 LABOR: Delta-T warrants to Owner that the labor performed and materials
    supplied will be free from defects in workmanship and will be of good
    quality until twelve (12) months from completion of the Performance Test.
    OWNER'S SOLE AND EXLCUSIVE REMEDY IN CASE OF BREACH OF THIS WARRANTY SHALL
    BE REPAIR OR REPLACEMENT AS PROVIDED IN THIS SECTION 12.4. If any defect
    covered by the above warranties is discovered within the warranty period,
    Delta-T shall, subject to the provisions set forth below, repair or replace
    the defective workmanship. The decision to repair or replace shall be made
    by Owner. If Owner and Delta-T do not agree on whether repair or replacement
    is the most appropriate remedy, and if the remedy recommended by Delta-T
    would not impair the performance of the Work or otherwise materially
    diminish the value of the Work, then Delta-T shall not be required to

                                       22
<PAGE>

    perform the remedy elected by Owner unless Owner pays Delta-T the excess
    cost of performing such remedy over and above the cost of performing the
    remedy recommended by Delta-T. Delta-T shall in no case have any liability,
    under this warranty or otherwise, for any defect or deterioration which
    results from failure of Owner to provide any feedstock, utilities, or other
    supplies, services or conditions specified in Exhibit C, force majeure,
    improper operation or maintenance including damage caused by freezing,
    foreign substance or impurity introduced into the equipment, or any other
    matter not within Delta-T's control

    12.5 PROCESS WARRANTY: Delta-T warrants that the Plant will perform as set
    forth in Exhibit D during the Performance Test. Delta-T shall not have any
    obligation or liability for failures or defects due to ordinary wear and
    tear, corrosion or erosion, or as a result of improper operation, improper
    maintenance or operating conditions more severe than, or different from,
    those contemplated in the original design of the Work. OWNER'S SOLE AND
    EXCLUSIVE REMEDY FOR BREACH OF THIS WARRANTY IS PAYMENT BY DELTA-T OF
    LIQUIDATED DAMAGES AS SET FORTH AT EXHIBIT D.

    12.6 NO OTHER WARRANTIES: Delta-T's sole warranties to Owner under this
    Contract are the warranties set forth in this Section 12 and in Exhibit D.
    OWNER HEREBY ACKNOWLEDGES AND AGREES THAT DELTA-T MAKES NO OTHER WARRANTY
    UNDER OR BY VIRTUE OF THIS CONTRACT, WHETHER EXPRESS OR IMPLIED, AND WHETHER
    RELATED TO GOODS OR SERVICES, AND THAT DELTA-T MAKES NO WARRANTY OF ANY KIND
    TO ANYONE OTHER THAN TO OWNER.

    12.7 NOTICE OF WARRANTY CLAIM: Owner shall notify Delta-T of any defect
    covered by the warranty set forth in Section 12.5 and Exhibit D as provided
    at Exhibit D, and shall notify Delta-T in writing of any defect covered by
    any other warranty within thirty (30) Days after discovering such defect,
    and in no case later than thirty (30) Days after expiration of the
    applicable warranty period.

    12.8 PERFORMANCE IN EXCESS OF GUARANTEES: Performance of the Plant in excess
    of the performance guarantees shall in no way be construed to void the
    warranties set forth herein.

13. TRANSFER OF TITLE AND RISK OF LOSS

                                       23
<PAGE>

Title to, and risk of loss of, the Equipment or any part thereof and all
materials and components used, or to be used in the Plant, shall pass to Owner
upon delivery to the Work site. This provision, however, shall in no case be
deemed to alter any of the rights or obligations of any party under any
insurance policy provided under Exhibit G, or any waiver of subrogation set
forth in Section 14 below.

14. INSURANCE

    14.1 REQUIRED INSURANCE: Each Party shall carry the insurance coverage
    described in Exhibit G as insurance to be carried by it.

    14.2 ADJUSTMENT OF LOSS: Any loss insured under property or builders risk
    insurance required under this Section 14 shall be adjusted by the insurance
    carrier with the insured as fiduciary for the other party or parties whose
    interests are insured thereunder as their interests may appear, and the
    insured shall pay the proceeds due to them promptly. The insured shall bear
    the costs of the deductible, if any, under such policy.

    14.3 WAIVER OF SUBROGATION: Owner and Delta-T intend that all builder's risk
    policies purchased, or required to be purchased, in accordance with Exhibit
    G will protect Owner, Delta-T and all subcontractors at any tier, and will
    provide primary coverage for all losses and damages caused by the perils or
    causes of loss covered thereby. Owner and Delta-T waive all rights against
    each other and their respective subcontractors, officers, directors, agents
    and employees of the other arising out of or resulting from any of the
    perils or causes of loss covered by such policies and any other property
    insurance during the period prior to Final Completion and payment of all
    amounts due to Delta-T under this Contact. None of the above waivers shall
    extend to the rights that any Party making such waiver may have to the
    proceeds of insurance held by Owner as trustee or otherwise payable under
    any policy so issued. In addition, Owner waives all rights against Delta-T,
    its subcontractors at any tier and the officers, directors and employees and
    agents of any of them for business interruption and any other consequential
    damages caused by, arising out of or resulting from any such insured perils
    or causes of loss or any other peril or cause of loss whether or not
    insured. All policies required under the Contract shall be endorsed to
    include such waivers of subrogation, or confirmation of such waivers shall
    appear on the certificates of insurance required to be delivered under
    Section 14.4 below. Owner and the Delta-T shall require from each of their
    contractors and subcontractors who do work on the Project similar waivers,
    each in favor of the other parties enumerated in this Section.

                                       24
<PAGE>

    14.4 CERTIFICATES OF INSURANCE: Before commencing the Work, Delta-T and
    Owner shall each furnish the other with certificates evidencing the coverage
    required under Exhibit G from the insurance company or companies carrying
    the aforesaid coverage. These certificates will provide that the policies
    may not be amended or terminated unless at least thirty (30) days prior
    written notice is given to Owner and Delta-T. Failure of either Party to
    demand any such certificate prior to commencement of the Work shall not,
    however, be deemed to relieve any Party of its obligation to carry such
    insurance.

15.  INDEMNITY

    15.1 INDEMNITY BY DELTA-T FOR PERSONAL INJURY AND PROPERTY DAMAGE: Delta-T
    shall indemnify and hold harmless Owner and its agents and employees from
    and against all claims made by a third party for any, damages, losses and
    expenses, including, but not limited to attorney's fees, arising out of or
    resulting from Delta-T's performance of the Work, provided that any such
    damage, loss or expense: (1) is attributable to bodily injury, sickness,
    disease or death, or to injury to or destruction of tangible property (other
    than the Plant, Equipment or the Work itself) and (2) is caused in whole or
    in part by any negligent act or omission of Delta-T, its subcontractors, or
    anyone for whose acts Delta-T is liable. In the event that any such damage,
    loss or expense was caused in part by Owner or by any other person or
    entity, however, then Delta-T shall be obliged to pay only the portion of
    the damage, loss or expense, including reasonable attorney's fees as is
    attributable to its relative share of the negligence or omission which
    caused such damage, loss or expense.

    15.2 INDEMNITY BY DELTA-T FOR INTELLECTUAL PROPERTY: Notwithstanding
    anything to the contrary herein, Delta-T hereby warrants that the Plant, and
    the use thereof in an application described in the process description set
    forth at Exhibit A, as delivered by Delta-T under this Contract, when
    operated in accordance with Delta-T's operating instructions, will not
    infringe any United States patent, copyright, any trade secret, or any other
    intellectual property right held by others. Delta-T further agrees, upon
    receipt of notification from Owner of a lawsuit or claim against Owner for
    such an infringement, to promptly defend such claim with competent counsel
    of its own choosing. Delta-T further agrees, to indemnify Owner against any
    royalties, damages, orders, and court costs, awarded by a final,
    non-appealable judgment resulting from a finding of an infringement covered
    by this indemnity, or the settlement of a claim indemnifiable under this
    Section 15.2.

                                       25
<PAGE>

    15.3 CONDITIONS TO INDEMNITY: The indemnities set forth in Sections 15.1 and
    15.2 above all shall not apply to any design, process or product of a
    particular manufacturer or manufacturers, which is specified by Owner. These
    indemnities are valid only if (a) Owner gives notice of any claim or lawsuit
    for which it claims indemnity within time sufficient for Delta-T to contest
    such claim, (b) Owner cooperates fully and promptly with Delta-T in the
    defense thereof at Owner's expense for all items related to such defense for
    time of witnesses who are employees of Owner, costs related to travel,
    production of documents, fees for any counsel it elects to assist it in
    addition to counsel appointed by Delta-T for defense of the claim, and (c)
    Delta-T has full authority in defense of such lawsuit or claim and to settle
    such claim, provided that, it pays to Owner the cost, if any, of any change
    in operations resulting from such settlement. In no case shall Delta-T be
    liable under Sections 15.1 or 15.2 for any amount, including costs and
    attorney's fees, in excess of the limit set forth at Section 16 below.

    15.4 INDEMNITY BY OWNER: Owner shall indemnify and hold harmless Delta-T
    and its agents and employees from and against all damages, losses and
    expenses, including but not limited to attorney's fees, and arising or
    resulting from a claim, order, requirement or charge made or brought by a
    third party or by the federal, state or local government, or any department,
    agency or subdivision thereof, based, in whole or in part, on: (a) defects
    in title; (b) Owner's negligence; (c) hazardous materials, unless such
    materials were brought on the Site by Delta-T or its subcontractors; (d) the
    existence of any substance located on or under the Work site, unless such
    substance was brought on the Site by Delta-T or its subcontractors; (e) a
    condition of the Work site subject to any law or regulation related to
    protection of the environment; or (f) any other matters for which Owner
    shall have responsibility pursuant to this Contract. This indemnification is
    valid only if (a) Delta-T gives notice of any claim or lawsuit for which it
    claims indemnity within time sufficient for Owner to contest such claim, (b)
    Delta-T cooperates fully and promptly with Owner in the defense thereof at
    its expense for all items related to such defense for time of witnesses who
    are employees of Delta-T, costs related to travel, production of documents,
    fees for any counsel it elects to assist it in addition to counsel appointed
    by Owner for defense of the claim, and (c) Owner has full authority in
    defense of such lawsuit or claim and to settle such claim, provided that
    such settlement requires payment of monetary damages only and that Owner
    can, and does, pay the full cost of any such settlement.

                                       26

16. LIMITATION OF LIABILITY

In no case shall Delta-T or Owner have any liability to the other under or
arising from any performance, delay in performance, or breach of this Contract
for any indirect, incidental, reliance, punitive, exemplary, or consequential
damages (including, without limitation, lost profits, increase in costs of goods
or services resulting from delay, cost of capital or losses due to business
interruption) whether based on contract, tort or other legal theory, whether or
not Delta-T had knowledge of the damages that might result, except as expressly
provided otherwise under these General Conditions and except in case of breach
of Section 17 below, to which this limitation shall not apply. Subject to the
limitations set forth in this paragraph, nothing shall preclude Delta-T or Owner
from recovering direct damages. Furthermore, Delta-T's maximum cumulative
liability for any and all direct damages under this Contract, including without
limitation liquidated damages payable Exhibit D, shall be as follows:

        1. 100% of the Contract Sum as set forth in paragraph 8.1 beginning at
commencement of the Project. (For purposes of paragraph 16 only, the computation
of the Contract Sum shall not include any Change Orders as provided for in this
Agreement.) The 100% of Contract Sum maximum liability shall be reduced in
amounts equal to the payments made by Owner to Delta-T under this Agreement.
Once the Owner has paid Delta-T 50% of the Contract Sum, Delta-T's maximum
liability shall remain fixed at 50% of the Contract Sum until such time as the
Plant reaches Mechanical Completion.

        2. Once the Plant reaches Mechanical Completion, Delta-T's maximum
cumulative liability shall be reduced to Thirteen Million Dollars
($13,000,000.00), inclusive of the Retainage provided for under this Agreement.
Delta-T's maximum liability shall remain fixed at $13,000,000.00 until such time
as the Plant reaches 90% of the Performance Guaranty values set forth in this
Agreement.

        3. Upon reaching 90% of the Performance Guaranty amounts, Delta-T's
maximum cumulative liability shall be reduced to the amount of the Retainage
which shall be released pursuant to Exhibit B.

        The limitations set forth in this Section shall not apply to limit or
restrict available insurance nor shall it effect warranty or indemnification
obligations hereunder.

                                       27

17.  CONFIDENTIALITY

    17.1 CONFIDENTIAL INFORMATION: Owner shall not use any Confidential
    Information for any purpose other than the purposes permitted under this
    Contract and shall not use any Delta-T Technology except as permitted under
    Section 17.2. Furthermore, Owner shall not disclose any Delta-T Technology
    or other Confidential Information to, or permit the visual inspection of the
    Equipment, Plant or Work embodying any Confidential Information by, any
    person or entity other than its employees who need to have access to such
    data in order to operate the Plant, any consulting engineers retained by
    Owner, or representatives of the construction lender unless (a) such access
    is required by local, state or federal regulatory authorities, or (b) it is
    necessary to do so in order to maintain or repair the Plant or to facilitate
    interface of connection of the Equipment to other equipment or facilities of
    Owner, and Owner has complied with the first right of refusal requirements
    of Section 17.3 below; and (c) Owner first obtains a signed confidentiality
    agreement from such person in the form attached hereto as Exhibit H and
    provided a copy of the same to Delta-T. In addition to the foregoing,
    Delta-T shall have the right to reasonably object to Owner's request to
    disclose Confidential Information to third parties. Furthermore, Owner shall
    not disclose any Confidential Information to any of its employees other than
    those who have been made aware of and agreed to comply with the
    non-disclosure provisions of this Section 17.1. Owner shall not disclose any
    Confidential Information pursuant to court order or other legal process
    unless it is advised by its legal counsel that it is legally required to do
    so; it has promptly given Delta-T notice of such order or process so that
    Delta-T can seek to obtain a secrecy order; and, it uses all other
    reasonable means to ensure the confidential treatment of such information.
    In particular, but without limitation, in no event will Owner knowingly
    allow an entity that is a competitor of Delta-T to tour the Plant, or to
    provide maintenance or other services that would expose it to Delta-T
    Technology, as long as there is a reasonably feasible alternative to
    complete the maintenance through Delta-T or a non-competitor of Delta-T. A
    "competitor" for this purpose shall mean entities listed on Exhibit I, and
    such other entities as Delta-T may advise Owner from time to time in
    writing. Owner shall maintain a log of each individual (other than its
    employees and contractors) who has access to the Delta-T Technology, and the
    date and purpose for such access. Owner shall provide a copy of such log to
    Delta-T upon request.

                                       28
<PAGE>

    17.2 LICENSE OF DELTA-T TECHNOLOGY: Owner acknowledges that Delta-T is and
    shall remain the sole owner of the Delta-T Technology, and of the copyrights
    in all the drawings, manuals and other documents provided by Delta-T under
    this Agreement. Delta-T grants to Owner, subject to the conditions of this
    Agreement, a non-exclusive, paid-up, non-transferable right to use in
    perpetuity the Delta-T TECHNOLOGY, without right to grant such rights to
    others, solely for the purposes of:

          a.   Use and operation of the Plant.

          b.   Maintenance, repair, and optimization or enhancement of the
               Plant.

    Optimization and enhancement, for this purpose, shall include
    de-bottlenecking, but shall not include expanding the physical dimensions of
    the distillation columns and molsieve vessels specified in the design, or
    adding to the original number of distillation columns and molsieve vessels
    delivered by Delta-T under this Contract. Delta-T agrees that if Owner
    wishes to expand or add distillation columns or molsieve vessels in order to
    increase the production capacity of the Plant, Delta-T shall negotiate in
    good faith with Owner to agree to a grant of rights, and corresponding
    technology fee, to allow for such expansion or addition. The right granted
    under this Section 17.2 shall become effective only upon payment in full of
    the entire amount due to Delta-T under Section 8 above, and Owner shall have
    no right to use any such Delta-T Technology, for any purpose other than
    Plant Startup and conducting the Performance Test until the payment of all
    such amounts is made per the terms of this Contract.

    17.3 FIRST RIGHT OF REFUSAL: Owner shall not disclose any Delta-T Technology
    for the purpose of maintenance or repair of the Plant to anyone other than
    its employees or other entities who need to have access for those purposes
    unless (a) Owner first obtains a fully executed Non-Disclosure Agreement in
    a form identical to Exhibit H from each such person or entity who may be
    exposed in any way to Delta-T's Technology and (b) Owner provides Delta-T
    with a copy of such fully executed Non-Disclosure Agreement.

18.  DISPUTE RESOLUTION

                                       29
<PAGE>

    18.1 EXECUTIVE CONFERENCE OR MEDIATION: In the event of any controversy or
    claim arising out of or related to this Contract, or the interpretation,
    termination or breach hereof, other than default in payment due under
    Section 8 above which shall be subject to the provisions of this Section at
    Delta-T's option, the Parties shall, upon the written request of either of
    them, attempt to resolve the matter by agreement of the representatives of
    the Parties. Such representatives shall be at least one management level
    above the individuals who have had direct responsibility for performance of
    the Contract, or the highest level of management of any Party whose highest
    level of management has had direct responsibility for such performance. Such
    representatives shall meet in person or by telephone or teleconference at
    least once, and shall attempt to resolve any matter raised by either of them
    by the written notice requesting such resolution for a period of at least
    thirty (30) Days. In the event that the Parties are unable to resolve the
    dispute by agreement of such representatives within such thirty (30) Day
    period, then at the written request of either Party, the Parties shall
    submit the matter to mediation under the then current rules of mediation and
    conciliation of the American Arbitration Association. The Parties shall
    attempt to resolve any matter submitted to mediation under this Section 18.1
    within thirty (30) Days after the date of delivery of the written request
    for mediation.

    18.2 ARBITRATION: Any controversy or claim arising out of or related to this
    Contract, or the interpretation, termination or breach hereof, which cannot
    be resolved by mutual agreement of the parties or by mediation within the
    time periods provided at Section 18.1 above shall be submitted to binding
    arbitration in accordance with the applicable rules of the American
    Arbitration Association. The place of arbitration shall be Nebraska. Neither
    Party shall submit any such matter to arbitration unless the parties have
    been unable to resolve it by mediation for a period of at least thirty (30)
    days after the date of request for mediation. Any party who files a notice
    of demand for arbitration must assert in the demand all claims then known to
    that party against the other. Judgment upon any award rendered by an
    arbitrator or arbitrators under this Contract may be entered upon it in
    accordance with applicable law in any court having jurisdiction thereof, but
    either party hereto shall have the right to contest such award on the
    grounds that it is contrary to applicable law.

    18.3 INJUNCTIVE RELIEF: Notwithstanding the foregoing, Delta-T may seek
    injunctive relief from any court of competent jurisdiction at any time in
    case of a breach of Section 17 above.

    18.4 ATTORNEY'S FEES AND COSTS: All costs, expenses and attorney's fees
    resulting from the litigation or arbitration of any claim under this
    Contract shall be paid by the losing party to the prevailing party,
    considering the totality of the circumstances, including any offers of
    settlement.

                                       30
<PAGE>

19.     FORCE MAJEURE

        19.1 No delay in, or failure of, performance by either Party under this
Contract will constitute default hereunder or give rise to any claim for damages
if and to the extent caused by an occurrence beyond the control of the party
affected, to include but not limited to, acts of governmental authority, acts of
God, strikes or other concerted acts of workmen, fire, flood, abnormal weather,
explosions, riots, war, rebellion or sabotage.

        19.2 Adjustments to all scheduled dates shall be made as a result of a
delay caused by a Force Majeure Event and shall be equal to the actual number of
days of delay incurred by Delta-T or its subcontractors.

20.  GENERAL PROVISIONS

    20.1 ASSIGNMENT: Neither Delta-T nor Owner shall assign or transfer its
    duties or obligations hereunder without the prior written consent of the
    other, which consent shall not be unreasonable withheld. This Contract shall
    be binding upon and shall inure to the benefit of the Parties and the
    successors and permitted assigns of Owner and Delta-T.

    20.2 ENTIRE CONTRACT; WAIVER; AMENDMENT: These General Conditions and the
    attached Exhibits constitute the full and complete contract between the
    parties hereto with respect to the subject matter hereof. There are no
    statements, agreements, understandings, representations or trade customs of
    any kind, express or implied, concerning the subject matter which are not
    merged herein or superseded hereby. A waiver of any of the terms of this
    Contract shall not bind either party unless signed by one of its duly
    authorized representatives. Waiver by either Party of any default by the
    other party hereunder shall not be deemed a waiver by such Party of any
    default by the other which may occur thereafter. This Contract may only be
    modified or amended by an agreement in writing executed by both Parties
    hereto.

    20.3 GOVERNING LAW: The validity, performance, construction and effect of

21.  PROCEEDING BEFORE FINANCIAL CLOSING

     21.1 The Owner has the option to request that Delta-T initiate engineering
          tasks prior to financial closing. If this option is elected, until
          such time as Owner notifies DELTA-T that Owner has secured financing
          sufficient to permit Owner to pay all its financial obligations in
          connection with building of the Plant upon terms acceptable to Owner,
          (the "Financing"), DELTA-T shall only perform (i) the tasks described
          on Exhibit J and (ii) such other portions of the Work as Owner may
          from time to time specifically request and as DELTA-T may agree in a
          writing signed by it to perform. DELTA-T shall have the right to
          receive from Owner reasonable assurance of Owner's ability to pay for
          Work that Owner asks it to perform prior to performing any such Work
          until such time as DELTA-T shall have received written notice from the
          Owner, and evidence reasonable acceptable to DELTA-T, that the
          Financing has been secured. If this option is elected, Owner shall
          provide DELTA-T a topographical and legal survey of the Plant site,
          and the amount due to DELTA-T under Exhibit B-3, prior to commencement
          of Work under this Section 21. DELTA-T's commencement of Work under
          this Section 21 shall in no case be deemed a waiver of Owner's
          obligation to provide the items that it is required to provide under
          Section 3 above prior to performing Work other than the Work described
          on Exhibit J.

     21.2 If DELTA-T does not receive notice that Financing has been secured on
          or before September 15, 2006, then DELTA-T may terminate this
          Agreement at any time thereafter without penalty or expense of any
          kind upon at least 30 days' written notice of its intent to terminate.
          In such case, the termination shall become effective at the end of the
          notice period unless DELTA-T receives notice of Owner's receipt of
          Financing prior to the effective date of termination. Upon termination
          under this Section, Owner's rights in the DELTA-T technology under
          Section 17.2 above shall immediately cease, and Owner shall return all
          documents and other materials containing any such technology to
          DELTA-T and certify to DELTA-T in writing that it has done so. Upon
          such termination, neither Party shall have any obligations to the
          other under this Agreement (except for such obligations as survive
          under Section 20 above), except that Owner shall be obligated to pay
          DELTA-T for all Work performed by DELTA-T prior to date of such
          termination.
