      commencement of the Factory Acceptance Test, SELLER shall provide BUYER with
      technical instruction in the operation and maintenance of the Equipment as
      described in **Appendix

      Factory Acceptance Test after having been given notification in accordance
      with
      Section 5.2.1 above,
      and if SELLER conducts the Factory Acceptance Test in BUYER’s absence, and
      confirms that the Equipment meets the Technical Specifications, then SELLER

      the
      Port of Shipment. The expenses of any such inspection shall be for BUYER’s
      account.




5.2.5.  The
      Factory Acceptance Test shall not be a substitute for the inspection of the
      Equipment at the Port of Unloading or the Work Site, or as a substitute for
      the
      Commissioning Test, and the Factory Acceptance Test shall not release SELLER
      from its warranty obligations as further specified in this
      Agreement.




5.3.  Installation

      and
      SELLER shall conduct the Commissioning Test to confirm that the Equipment
      operates in accordance with the Technical Specifications. Provided that all
      of
      the Technical Specifications for the Equipment are satisfied, BUYER and SELLER
      shall each sign the Certificate of Commissioning; provided, however, that if
      BUYER does not attend the Commissioning Test, and if SELLER conducts the
      Commissioning Test in BUYER’s absence, and confirms that the Equipment meets the
      Technical Specifications, then SELLER may sign the Certificate of Commissioning
      and the Commissioning Test shall have been deemed completed without the
      Certificate of Commissioning being signed by BUYER.




5.4.  Notwithstanding
      anything to the contrary in this Agreement, BUYER or SELLER’s execution of the
      Factory Acceptance Certificate or the Certificate of Commissioning shall not
      release SELLER from its warranty for the Equipment as described in

        other expenses (including attorneys’ and expert witnesses’ costs and fees)
        arising from or relating to any breach of any representation, warranty,
        covenant, or obligation of SELLER in this Agreement or any intentional
        misconduct or negligence by SELLER or any of SELLER’s agents or subcontractors

  10.  Termination
        & Cancellation
  10.1.  The
        term
        of this Agreement shall begin on the Effective Date and, unless previously
        terminated as hereinafter set forth, shall remain in force until the expiration
        of the Warranty Period.
  10.2.  Each
        Party may, at its discretion, upon written notice to the other Party, and
        in
        addition to its rights and remedies provided under this Agreement or any
        other
        agreement executed in connection with this Agreement and at law or in equity,
        terminate this Agreement in the event of any of the following:
  10.2.1.  Upon
        a
        material breach of the other Party of any material provision in this Agreement,
        and failure of the other Party to cure such material breach within one hundred
        eighty (180) days after written notice thereof; provided, however, that such
        cure period shall not modify or extend the sixty (60) day cure period for
        SELLER’s delivery obligations pursuant to Section 4.4 above;
        and provided, further that such one hundred eighty (180) day cure period
        shall
        not apply to BUYER’s failure to make any payment to SELLER pursuant to this
        Agreement. In the event of BUYER’s failure to make payment on the 30-day payment
        terms set forth in Section 3.1 hereof, termination by SELLER shall require
        the
        issuance of a written notice of default containing the threat of immediate
        termination if payment is not made within an additional grace period of not
        less
        than ten (10) business days.
  10.2.2.  Upon
        the
        voluntary or involuntary initiation of bankruptcy or insolvency proceedings
        against the other Party; provided, that for an involuntary bankruptcy or
        insolvency proceeding, the Party subject to the proceeding shall have sixty
        (60)
        working days within which to dissolve the proceeding or demonstrate to the
        terminating Party’s satisfaction the lack of grounds for the initiation of such
        proceeding;

        the
        other Party (i) becomes unable, or admits in writing its inability, to pay
        its
        debts generally as they mature, (ii) becomes insolvent (as such term may

  10.3.  In
        addition to BUYER’s termination rights pursuant to Section 1 0.2 above,
        BUYER may terminate this Agreement upon written notice to SELLER, and without
        any further obligation or liability to SELLER, for any of the following
        reasons:
  10.3.1.  For
        BUYER’s convenience at any time prior to payment of the Initial Payment to
        SELLER;
  10.3.2.  If
        SELLER
        does not sign the Consent or provide the Legal Opinion pursuant to
        Section 13 below;
  10.3.3.  If
        at any
        time prior to delivery of the Equipment, FOB Port of Shipment, BUYER has
        a
        justifiable reason to believe that SELLER will be more than sixty (60) days
        late
        in the delivery of the Equipment, BUYER may immediately cancel this agreement
        and shall, in addition to all other rights and remedies available in law
        and
        equity, be entitled to a refund of the Initial Payment plus the maximum amount
        of liquidated damages payable pursuant to Section 4.4 above.
  10.4.  SELLER
        may terminate this Agreement without any further obligation or liability
        to
        BUYER if BUYER has not paid the Initial Payment within one hundred eighty
        (180)
        days after the Effective Date. Upon such termination, each of BUYER and SELLER
        shall be released from any further obligations or liability to the other
        Party
        under this Agreement.
  10.5.  Upon
        the
        expiration or termination of this Agreement howsoever arising, the following
        Sections shall survive such expiration or termination:
        Sections 1 (Definitions), 7.3 (Warranty Claims), 8 (Indemnification), 9 (Non-solicitation), 1 0 (Termination & Cancellation), 11 (Force
        Majeure), 12 (Limitations of Liability), and 14 (General
        Provisions).
  11.  Force
        Majeure. Neither Party shall be liable to the other Party for failure of or
        delay in performance of any obligation under this Agreement, directly, or
        indirectly, owing to acts of God, war, war-like condition, embargoes, riots,
        strike, lock-out and other events beyond its reasonable control which were
        not
        reasonably foreseeable and whose effects are not capable of being overcome
        without unreasonable expense and/or loss of time to the affected Party (i.e.,
        the party that is unable to perform). If such failure or delay occurs, the
        affected Party shall notify the other Party of the occurrence thereof as
        soon as
        possible, and the Parties shall discuss the best way to resolve the event
        of
        force majeure. If the performance of SELLER is delayed for Force Majeure
        for a
        cumulative period of thirty (30) days or more, SELLER will use commercially
        reasonable efforts to transition its production of the Equipment for the
        duration of the Force Majeure to an alternate source. If the conditions of
        Force
        Majeure continue to materially impede performance of any material obligation
        under this Agreement for a period of more than three (3) consecutive calendar
        months (and, only if SELLER is the affected Party, SELLER has not used
        commercially reasonable efforts to transition its production of the Deliverables
        as provided in the immediately preceding sentence), then the non-affected Party
        shall be entitled to terminate this Agreement by 30 days prior written notice
        to
        the other Party.

        and
        SELLER shall perform its obligations hereunder in favor of the Agent or the
        Subsequent Transferee, as the case may be.

        the
        enforcement of creditors’ rights generally, and (b) general principles of equity

        BUYER. SELLER also irrevocably waives any right SELLER may have to a jury
        trial.
  15.2.  Severability .

        valid
        and enforceable to the maximum extent permitted by law.
  15.3.  No

        written consent. Any attempted assignment, delegation, or transfer in violation
        of the foregoing will be null and void. BUYER may assign this Agreement,
        or any
        of its rights under this Agreement to any third party with or without SELLER’s
        consent.
  15.4.  Notices .

        relation to FAT (factory acceptance tests) and later in Hoku plant in relation
        to installation, commissioning and final acceptance. For each type of equipment
        the topics will be: Overall description of equipment, installation, operation,
        and maintenance. The total time spent during FAT for this purpose two week
        and
        the total at Hoku-site 6 weeks incl. time for installation supervision. The
        reason it is taken together is that the installation process is often quite
        practical also used for demonstration of certain aspects of the
        equipment.
  The
        FAT
        will include 2 weeks of training for the BUYER at the SELLER
        Facility.

        and
        range of rotation and vertical movement), alignment and end vacuum.
  Phase
        II.
        In the second part of the tests, the operational performance will be proven
        as
        follows:
