      (c)   Letters of Credit.

            (i)   GT Letter of Credit. Within ten (10) Business Days after the
                  Commencement Date, GT shall open an irrevocable confirmed
                  standby letter of credit in favor of Customer in an amount
                  equal to the First Installment (the "GT Letter of Credit")
                  against GT's failure to Deliver the Equipment. The GT Letter
                  of Credit shall be valid (subject to the reductions as set out
                  below in this Section 3.2(c)(i)) until Delivery of the last
                  item of Equipment, at which time the GT Letter of Credit shall
                  expire and no longer be valid, GT may, in its sole discretion,
                  choose to use either of the following banks as issuing banks
                  for the GT Letter of Credit: (i) Citizens Bank, and/or (ii)
                  any other U.S. bank designated by GT (or any non-U.S. bank
                  designated by GT and reasonably acceptable to the Customer).
                  The GT Letter of Credit may be reduced by GT by the amount
                  equal to the sum of thirty-five percent (35%) of the Unit
                  Price for an item of Equipment that has been Delivered to
                  Customer upon presentation by GT to its issuing bank of a
                  notarized letter from GT certifying that GT has the right to
                  reduce the GT Letter of Credit under the terms and conditions
                  of the Agreement in the amount requested. Upon Delivery of the
                  last item of Equipment, the GT Letter of Credit shall expire
                  and no longer be valid. Prior to opening the GT Letter of
                  Credit, GT shall provide a draft of the terms of the GT Letter
                  of Credit to Customer and shall discuss any reasonable
                  comments thereto that Customer may have, provided that such
                  comments are provided to GT in a timely manner so that GT can
                  meet its timing obligation to set up the GT Letter of Credit
                  as set forth herein.

            (ii)  Payment Against GT Letter of Credit. Payment against any GT
                  Letter of Credit shall be available to Customer at any time
                  and from time to time, upon presentation to GT's issuing bank
                  of a notarized letter from Customer (A) certifying that GT has
                  failed to Deliver the Equipment as set forth in Section 4.2
                  and for a period of three (3) months thereafter (provided that
                  such delay is not directly or indirectly due or otherwise
                  attributable, in whole or part, to any act or omission of
                  Customer (or for the avoidance of doubt, any Force Majeure
                  Event)); and (B) specifying the

                  the amount payable by GT hereunder as a result of such late
                  Delivery; provided that Customer shall have given GT at least
                  ten (10) Business Days prior notice. Payment against the GT
                  Letter of Credit with respect to late Delivery of Equipment,
                  as set forth above, shall be available in an amount equal to
                  the sum of thirty-five percent (35%) of the Unit Prices for
                  such item of Equipment that was not Delivered. Notwithstanding
                  the foregoing, no payment shall be made against the GT Letter
                  of Credit, if GT has previously provided documentation of
                  Delivery of such item of Equipment to GT's issuing bank or
                  payment or other fulfillment of such obligation, as
                  applicable, to GT's issuing bank, or a notarized letter from
                  GT certifying that GT has Delivered such item of Equipment,
                  made such payment or otherwise fulfilled such obligation, as
                  applicable.

            (iii) Customer's Letter of Credit. Within (A) one hundred (100) days
                  after the Effective Date, Customer shall open a confirmed
                  irrevocable letter of credit in favor of GT in an amount equal
                  to fifty million eight hundred and seventy-five thousand U.S.
                  dollars (US $*) (i.e., one-half of fifty-five percent (55%) of
                  the Purchase Price) and (B) two hundred (200) days after the
                  Effective Date, Customer shall increase such letter of credit
                  by an additional fifty million eight hundred and seventy-five
                  thousand U.S. dollars (US $*) (i.e., the second one-half of
                  fifty-five percent (55%) of the Purchase Price); in each case
                  against Customer's failure to pay Installments as they become
                  payable, and/or for GT to draw down on to receive payment of
                  any Installment(s) (whether because Customer has not paid the
                  Installment by the applicable date required under this
                  Agreement or because GT opts, in its sole discretion, to
                  receive payment of any Installment by drawing down on the
                  Customer Letter of Credit (as set forth in Section 3.2(b))
                  (the "Customer Letter of Credit"). The Customer Letter of
                  Credit shall be reduced by each Installment payment (or, with
                  respect to the Delivery Installments and the Startup
                  Installments, each partial installment thereof paid to GT
                  pursuant to Section 3.2(a)) paid to GT after the date the
                  Customer Letter of Credit was opened, upon Customer's payment
                  thereof in accordance with Section 3.2(a). The Customer Letter
                  of Credit shall be valid until Customer's payment of all of
                  the Installments to GT in accordance with the terms and
                  conditions of this Agreement pursuant to Section 3.2(a), and
                  presentation by Customer to its issuing bank of a notarized
                  letter from Customer certifying that Customer has the right to
                  reduce the Customer Letter of Credit under the terms and
                  conditions of this Agreement in the amount requested. The
                  issuing bank shall be the Bank of China, and, if a confirming
                  bank is requested by GT, it shall be either the Industrial and
                  Commercial Bank of China or the Commercial Bank of China. The
                  terms of the Customer Letter of Credit shall be reasonably
                  acceptable to GT. Prior to opening the Customer Letter of
                  Credit, Customer shall provide a draft of the terms of the

                  reasonable comments thereto that GT may have, provided that
                  such comments are provided to Customer in a timely manner so
                  that Customer can meet its timing obligation to set up the
                  Customer Letter of Credit as set forth herein.

                  Customer Letter of Credit shall be available to GT at any time
                  and upon time to time, upon presentation to the issuing bank
                  of a notarized letter from GT certifying that: (A) an
                  Installment is due and payable pursuant to Section 3.2(a) (if
                  GT opts to draw down on the Customer Letter of Credit instead
                  of receiving payment by wire transfer from Customer, as set
                  forth in Section 3.2(b)); and/or (B) Customer has breached its
                  payment obligations hereunder and failed to pay, in whole or
                  part, one or more Installment payments pursuant to the
                  Installment schedule set forth in Section 3.2(a) or the other
                  terms or conditions of this Agreement. GT shall be entitled to
                  full payment of such overdue Installments, together with any
                  interest payable by Customer to GT with respect thereto
                  pursuant to Section 3.2(b).

            (v)   Requirements for Letters of Credit. All letters of credit
                  required hereunder shall comply with the Uniform Rules and
                  Customs for Documentary Letters of Credit (Publication of the
                  International Chamber of Commerce #500, 1993 revision).

      (d)   Withholdings. All payments due or payable to GT under this Agreement
            shall be paid in full, regardless of whether Customer is required to
            withhold or to apply any taxes, charges, levies or other duties on
            payments made under this Agreement. If Customer is required to
            withhold or to apply any taxes, levies or other duties on payments
            made under this Agreement, then Customer shall gross up such
            payments so that GT receives the payment in full regardless of any
            withholdings or application of any taxes, levies or other duties on
            payments made under this Agreement, and if GT applies to obtain
            credit for the amount of the withholding or application, and if
            obtained, such amount shall be repaid by GT to Customer when and if
            it is received by GT.

</Table>

      Notwithstanding anything contained herein, (a) for purposes of the timing
      of Delivery and the Delivery schedule set forth above in the table,
      Delivery shall be deemed to have occurred when such item is made available
      to the carrier for transport to Customer; and (b) GT shall not be
      responsible for any delay arising after such item of Equipment is made
      available to the carrier, and if such item of Equipment is lost, damaged
      or destroyed after it is made available to the carrier, the Parties shall
      mutually agree upon a revised Delivery schedule for such item of Equipment
      and Customer hereby acknowledges and agrees that GT shall not have any
      responsibility or liability with respect to any such item of Equipment and
      Customer shall not have any right to terminate this Agreement pursuant to
      Section 8.3(a) in connection with any such delay). The Parties also hereby
      acknowledge and agree that in no event shall GT be considered to be in
      breach hereunder due to any delay in making any Equipment to the carrier
      for transport in the country of manufacture, until after such time, if
      then, as GT is at least more than ninety (90) days late under the terms
      and conditions of this Agreement (and, for the avoidance of doubt, this
      Section shall be subject to Section 10.6 and therefore, such ninety (90)
      day period shall be extended by any period during which there is a Force
      Majeure Event).

4.3   DELIVERY BY AIR FREIGHT. If Customer requests Delivery by air instead of
      ocean shipment for any item(s) of Equipment (assuming that such Equipment
      can be Delivered by air transport on or prior to the Delivery schedule set
      forth in Section 4.2), then, for the

                                       16
<PAGE>

      avoidance of doubt, Customer shall reimburse GT pursuant to Section 4.1
      for all charges for freight, insurance, VAT and other taxes and duties for
      such air shipment.

4.4   INSPECTIONS.

      (a)   Observation of Packaging. If requested by Customer, GT shall provide
            Customer with reasonable advance written notice of the anticipated
            Equipment packing dates prior to shipment, and Customer at its
            option shall have the right to have its representative or
            representatives present at GT's (or its vendor's) facilities where
            the Equipment is being manufactured to observe the condition and
            packaging of Equipment at a day and time specified by GT. GT shall
            not have any obligation to delay packaging or shipment of any
            Equipment if for any reason Customer's representative does not show
            up on the date and at the time specified by GT.

      (b)   Inspections of Equipment After Packaging. If requested by Customer
            in a timely manner, Customer may inspect the external packaging and
            crating for each shipment of the Equipment in the presence of GT or
            its agent at the port of the country of manufacture through its
            representative or representatives at a day and time specified by GT;
            provided that such inspection shall be limited to a visual
            inspection for obvious physical damage or quantity discrepancies
            that are evident without opening or otherwise tampering with any of
            the packaging or crating materials, provided further that GT shall
            not have any obligation to delay Delivery of any Equipment if for
            any reason Customer's representative is not available on the date
            and at the time specified by GT.

      (c)   Condition to Access. Notwithstanding anything contained herein, as a
            condition to GT permitting Customer or its personnel or any other
            representatives (and/or any other persons or entities who GT is
            willing to permit access, as determined by GT in its sole
            discretion) ("Customer Representatives") to access any of the
            facilities of GT or any of its contractors or vendors, Customer and
            its Customer Representatives shall, if requested by GT (and/or by
            any of its contractors or vendors), sign an agreement that (i)
            protects GT's and GT's contractors' and vendors' confidential
            information, (ii) requires compliance with GT's and its contractor's
            and vendors' policies and procedures, as applicable, and (iii)
            provides that GT is a third party beneficiary thereof and/or such
            other similar types of provisions as may be requested by GT and/or
            its contractors or vendors.

      (d)   Final Inspection on Arrival. Within ten (10) Business Days after
            arrival at the port of destination of an item of Equipment, Customer
            shall inspect such item of Equipment for any defect or damage that
            is reasonably discoverable upon physical inspection of such item of
            Equipment and that is unrelated to Customer's shipment of such
            Equipment. Customer shall notify GT in writing within such ten (10)
            Business Day period of any such defect in and/or damage to such Unit
            of Equipment. If GT does not receive such notice of defect and/or
            damage with respect to any Unit of Equipment within such ten (10)
            Business Day period after

                                       17
<PAGE>

            receipt by Customer of a Unit of Equipment, then Customer shall be
            deemed to have accepted such Unit of Equipment and to have waived
            any claim or remedy with respect to any such defect and/or damage.
            If Customer notifies GT of any such defect and/or damage within the
            ten (10) Business Day period and such defect and/or damage exists,
            then Customer shall be entitled, as its sole and exclusive remedy
            for any such defect and/or damage to any item of Equipment, to the
            remedies set forth in Section 9.2 (c), subject, however, to the
            exceptions set forth in Section 9.2(b). For the avoidance of doubt,
            in no event shall GT have any responsibility or obligation hereunder
            with respect to any defect or damage to any item of Equipment that
            occurs after Delivery of an item of Equipment and that is not
            attributable to GT (except to the extent covered by the warranty
            under Section 9.2(a) and not subject to any exceptions set forth in
            Section 9.2(b)).

4.5   BOOKS AND RECORDS; AUDITS; INSPECTIONS; CONDITION TO WARRANTY;
      RE-CALCULATIONS; AND CONDUCT OF QUALIFYING RUNS.

      (a)   Books and Records. During the Warranty Period, Customer shall
            maintain accurate and complete books and records in sufficient form
            and detail to support the calculation of the Average Growth Rate,
            including logs of growth time and growth rate for each Run from each
            Reactor, as well as downtime between each Run, and all other
            supporting data and information as may be necessary to confirm the
            correctness and accuracy of all such calculations (and including as
            may be necessary to confirm any data generated through any runs that
            should have been excluded, as set out below in this Section). Any
            data generated through any runs that are interrupted, shut down or
            are subject to any errors or which are run other than in the
            ordinary course or which do not meet all written operating
            instructions provided by GT shall be excluded from any calculations
            hereunder.

      (b)   Notice of Non-Compliance with the Warranty; Audits; and Inspection.
            After GT's receipt of notice of any claim by Customer of
            non-compliance with the warranty set forth in Section 9.2(a), GT
            (and/or an auditor and/or representatives designated by GT) may,
            upon reasonable prior notice, (i) audit the books and records of
            Customer referenced above in Section 4.5(a), (ii) inspect the
            Reactors and Converters and other Equipment at Customer's site and
            observe the practices and procedures employed by Customer to operate
            the Reactors and Converters and the other Equipment to determine the
            Average Growth Rate. Such audits and inspections shall be conducted
            during normal business hours in a manner so as to not unreasonably
            disrupt Customer's normal operations.

      (c)   Re-Calculation of the Average Growth Rate. At GT's request, whether
            in response to any claim by Customer of non-compliance with the
            warranty set forth in Section 9.2(a), or otherwise with respect to a
            Reactor, Customer shall perform new Qualifying Runs for such Reactor
            and re-calculate the Average Growth Rate based upon such new
            Qualifying Runs, and GT shall have the right, at its sole option, to
            observe and comment upon any such Runs and re-calculations (or

                                       18
<PAGE>

            otherwise) and Customer shall in good faith cooperate and consult
            with GT in connection therewith and Customer shall comply with any
            directions provided to Customer by GT. If (x) Customer fails to
            comply with the foregoing, or (y) the re-calculation of the Average
            Growth Rate for the affected Reactor based upon such new Qualifying
            Runs shows that the Reactor does have the capacity to meet the
            Minimum Average Growth Rate and comply with the warranty set forth
            in Section 9.2(a), then GT shall be deemed to have complied with the
            warranty set forth in Section 9.2(a). If however, the re-calculation
            of the Average Growth Rate based upon such new Qualifying Runs
            confirms that a Reactor does not comply with the warranty set forth
            in Section 9.2(a), then Customer shall be entitled, as its sole and
            exclusive remedy for such breach of the warranty, to the remedies
            set forth in Section 9.2(c), subject, however, to the exceptions set
            forth in Section 9.2(b). For the avoidance of doubt, and
            notwithstanding anything contained herein, any data generated
            through any Rns that are interrupted, shut down or are subject to
            any errors or which are run other than in the ordinary course or
            which do not meet all written directions provided by GT shall be
            excluded from all of the applicable calculations and shall be
            re-calculated.

                           DOCUMENTATION AND SERVICES

5.1   DELIVERY OF DOCUMENTATION.

      (a)   Delivery of Documentation. GT shall deliver the Documentation
            (including the Basic Engineering Packages) to Customer pursuant to
            the Delivery schedule specified in Exhibit C, in electronic or other
            form or medium, as determined by GT but which is in a form or medium
            that is usable by Customer's engineers. Customer acknowledges and
            agrees that Customer's use of the Documentation shall be subject to,
            and in accordance with, the terms and conditions of the License.

      (b)   Language of Documents. All Documentation and other documentation to
            be delivered by GT to Customer hereunder shall be in English.

5.2   SERVICES. GT shall use commercially reasonable efforts to provide training
      for Installation, operation, and maintenance of the Equipment and Startup
      of the Reactors, and other related services, that may be reasonably
      requested by Customer and mutually agreed upon with GT, in each case as
      described and subject to the terms set out in Exhibit E ("Services"),
      including with respect to the rate payable by Customer for such Services.
      For the avoidance of doubt, Customer hereby acknowledges and agrees that
      GT is only providing Customer with assistance hereunder, and that Customer
      shall conduct and be responsible for the Installation, Startup, operation
      and maintenance of the Equipment and shall provide and be responsible for
      all local labor and support, including all of the costs thereof. For the
      avoidance of doubt, Customer, and not GT, shall be solely responsible for
      the Facility (including providing all engineering for the Facility and
      confirming all

                                       19
<PAGE>

      design details), and for the integrated system for the production of PV
      Polysilicon (including TCS synthesis/pre-purification, TCS
      distillation/purification, STC hydrogenation and TCS reduction by hydrogen
      (polysilicon deposition)), and integration with third party products and
      equipment.

                                 CONFIDENTIALITY

6.1   CONFIDENTIAL INFORMATION. In connection with this Agreement, a Party
      ("Receiving Party") may discover, receive, or otherwise acquire, whether
      directly or indirectly, information or materials (including intellectual
      property) related to the other Party ("Disclosing Party") or its
      Affiliates or Disclosing Party's or its Affiliates' businesses, or
      information or materials (including intellectual property) of third
      parties that Disclosing Party is obligated to keep confidential
      (collectively, in whatever form or medium, and including any such
      information or materials disclosed by one Party to the other Party, or
      otherwise obtained from the other Party, prior to the Effective Date,
      "Confidential Information"), subject to the provisions of Section 6.2 and
      Section 6.3. For the avoidance of doubt, and without limiting the
      foregoing, GT Confidential Information shall include, without limitation,
      the Basic Engineering Packages and other Documentation, the GT
      Intellectual Property and the Specifications. For the avoidance of doubt,
      Customer hereby acknowledges and agrees that any information in
      non-tangible form retained in the memories of any persons who have
      obtained or have any access to any GT Confidential Information
      ("residuals"), shall be included in the GT Confidential Information and
      may only be used by the Customer under the terms and conditions of the
      License. Confidential Information shall not include information (i) that
      is, or becomes, publicly known through no wrongful act or omission, direct
      or indirect, of the Receiving Party or its officers, directors, employees,
      consultants or agents, (ii) that was already known to Receiving Party
      without obligations of confidentiality prior to the receipt from
      Disclosing Party, as reasonably evidenced by the Receiving Party, and was
      legitimately in Receiving Party's possession, without any existing
      obligation to keep such information confidential, (iii) that Receiving
      Party independently develops, invents or conceives without the use of any
      Confidential Information of Disclosing Party, as evidenced by the
      Receiving Party's documentation in existence at the time of disclosure by
      the Disclosing Party, (iv) that Receiving Party receives or has received
      on a non-confidential basis from a source other than Disclosing Party that
      is entitled to disclose the same to Receiving Party; or (v) that was
      disclosed with the prior written approval of the Disclosing Party.

6.2   CONFIDENTIALITY OBLIGATIONS. GT shall (i) use Customer's Confidential
      Information solely in connection with exercise of its rights or
      performance of its obligations under this Agreement, and (ii) disclose
      Customer Confidential Information only as necessary to its Affiliates and
      each of their officers, employees, consultants, contractors, agents and
      other representatives whose duties relate to this Agreement and reasonably
      require familiarity with such information in order for GT to perform its
      obligations or exercise its rights hereunder. Customer may (i) use GT's
      Confidential Information as necessary to exercise Customer's rights under
      the License and subject to the terms and conditions thereof, and

                                       20
<PAGE>

      (ii) disclose GT's Confidential Information only as necessary to its
      officers and employees and if and to the extent each is authorized in
      writing by GT, its consultants and contractors, whose duties relate to
      this Agreement and reasonably require familiarity with such information in
      order for Customer to perform its obligations or exercise its rights
      hereunder and who are bound by a legally enforceable written obligation of
      confidentiality with terms which are the same as, or more stringent than,
      those set out herein, including obligations to prevent unauthorized access
      and to maintain the confidentiality of, and not disclose any of, the GT
      Confidential Information to any other person or entity. Receiving Party
      shall take such precautions to maintain and protect the confidentiality of
      the other Party's Confidential Information (including from any
      unauthorized access or use and from any disclosure or misappropriation) as
      it takes for its own most highly sensitive information, but in no event
      shall Receiving Party use less than a reasonable degree of care. In no
      event shall Receiving Party reverse engineer, decompile or otherwise
      attempt to discover or reproduce any technology or other intellectual
      property included in the Disclosing Party's Confidential Information
      (including, if any, source code for any software included in the
      Disclosing Party's Confidential Information). The foregoing
      confidentiality and other obligations shall continue hereunder
      indefinitely, or for the longest period of time permitted under applicable
      law or regulation, and shall survive expiration or termination of this
      Agreement for any reason. The non-disclosure obligations in this Section
      6.2 shall not apply to Confidential Information to the extent it is
      required to be disclosed (a) as required by judicial order or as otherwise
      required by applicable law or regulation (including under the rules of the
      United States Securities Exchange Commission); or (b) as required by
      applicable laws and regulations, including requirements under any stock
      exchange on which such Party is listed or may be listed; or (c) in
      confidence, and subject to obligations of confidentiality, to legal
      counsel, accountants, banks and financing sources and their advisors; or
      (d) to actual or potential acquirers, investors and lenders and their
      respective representatives under written confidentiality agreements that
      protect the confidentiality of the contents of this Agreement and the
      Confidential Information of the other Party; or (e) in confidence, in
      connection with the enforcement of this Agreement or any rights hereunder;
      provided however, that the Receiving Party making a disclosure pursuant to
      an exception set forth in the preceding subsections (a) or (b) of this
      Section shall provide the other Party with advance notice and shall, if
      requested by the other Party, to the extent practical and available,
      cooperate with the other Party in seeking confidential treatment of the
      information to be disclosed and/or to limit the scope of the proposed
      disclosure and minimization of the same (including application for a
      protective order).

6.3   NONDISCLOSURE OF AGREEMENT; PRESS RELEASES. Neither Party, nor its
      Affiliates, shall disclose, publish or otherwise reveal the contents of
      this Agreement to any third party without the prior express written
      consent of the other Party; provided that, each Party shall be permitted
      to disclose the terms and conditions of this Agreement as set forth in
      subsection (a) through (e) in Section 6.2. No press release referring to
      this Agreement or utilizing the other Party's name shall be made without
      the prior written consent of such other Party.

                                       21
<PAGE>

6.4   NON-SOLICITATION. During the term of this Agreement and for a period of
      two (2) years thereafter, Customer shall not solicit or hire, directly or
      indirectly, any of GT's or its Affiliates' respective officers, employees,
      contractors or consultants (unless Customer obtains GT's prior written
      consent (which consent GT may give or withhold in its sole discretion)).

                                    ARTICLE 7
                                 INDEMNIFICATION

7.1   INDEMNIFICATION. Subject to the exceptions in Sections 7.2 and 9.4, GT
      hereby agrees to indemnify, defend and hold Customer harmless from and
      against Losses resulting from any claim by a third party that the
      operation of the Equipment by Customer infringes the copyright or any
      other intellectual property rights of any third party that are registered
      in the United States (other than any patent rights that are not filed or
      published as of the Signing Date (which patents rights are hereby
      expressly excluded)).

7.2   CERTAIN EXCEPTIONS. GT shall have no obligation with respect to any claim
      of infringement based upon the Equipment or use thereof if (i) installed,
      operated or maintained in any manner other than in accordance with the
      Documentation, the Specifications and any instructions provided by GT,
      (ii) used for other than its intended purpose, (iii) repaired or
      materially altered, other than by GT, or (iv) combined with other
      equipment, materials or software, technology or other intellectual
      property not supplied by GT or not recommended or authorized by GT in
      writing.

7.3   REMEDIES FOR INFRINGEMENT. In the event any claim of actual or alleged
      infringement is made or threatened by a third party against Customer based
      upon the Equipment, then Customer shall promptly provide the details of
      any such claim to GT as soon as practicable, including copies of all
      relevant documents. Upon GT's receipt and review of such claim, or if GT
      otherwise reasonably believes (as determined by GT in its reasonable
      business judgment) that the Equipment or its use may infringe the
      intellectual property rights of a third party, GT may, at its cost and
      sole option, undertake such steps as GT determines are appropriate to
      avoid such infringement (including, for example, obtaining a license from
      the relevant party, modifying the Equipment and/or replacing the Equipment
      with non-infringing equipment). Customer shall reasonably cooperate with
      GT, at GT's cost and as requested by GT, to resolve any such claim and
      remedy and/or avoid any infringement and to limit any actual or potential
      liability or Losses arising from any infringing activities (including by
      providing GT with access to the Equipment to modify and/or replace
      Equipment), if and as may be requested by GT. In the event that, as
      determined by GT in GT's reasonable business judgment, it would not be
      commercially practicable to avoid or remedy any infringement, then
      Customer shall cease all actual or alleged infringing activities within no
      more than ten (10) Business Days of Customer's receipt of GT's written
      notice requesting Customer to do so and, at GT's sole option, Customer
      shall return to GT (freight prepaid by GT) or certify that it has
      destroyed the Equipment, and as Customer's sole and exclusive remedy, GT
      shall refund

                                       22
<PAGE>

      the Unit Price of such Equipment to Customer, less straight line
      depreciation of such Equipment over a ten (10) year period.

7.4   INDEMNIFICATION PROCEDURES. GT shall have the right to appoint counsel of
      its choosing and shall have sole control over the defense and/or
      settlement and/or other disposition of any claim or suit for which
      Customer is entitled to indemnification hereunder. Customer may
      participate and select its won respective counsel, at Customer's cost,
      upon notice to GT, unless there is a conflict of interest that would
      prevent representation by joint counsel, in which case, Customer may
      select respective counsel reasonably acceptable to GT and GT shall pay for
      Customer's counsel.

                                    ARTICLE 8
                               TERM; TERMINATION.

8.1   TERM. Subject to the occurrence of the Closing Condition as set forth in
      Section 8.2, the term of this Agreement shall commence upon the Effective
      Date and shall terminate (unless earlier terminated hereunder) the earlier
      of (x) the expiration of the Warranty Period, and (y) five (5) years from
      the Effective Date.

8.2   CLOSING CONDITION. The Parties hereby acknowledge and agree that, except
      for this Section 8.2 and Article 6 and Section 8.1 (which provisions shall
      be effective as of the Signing Date), notwithstanding anything else
      contained herein, none of the other terms or conditions of this Agreement
      shall be effective unless and until GT's Board of Directors has approved
      the terms and conditions of this Agreement (the "Closing Condition"). Upon
      satisfaction of the Closing Condition, all of the terms and conditions of
      this Agreement shall be effective and in full force and effect (the
      "Effective Date"). If the Closing Condition is not satisfied within
      forty-five (45) days of the Signing Date, this Agreement shall
      automatically and immediately terminate (unless otherwise mutually agreed
      in writing by the Parties).

8.3   TERMINATION. This Agreement may be terminated by either Party upon written
      notice to the other Party:

      (a)   by a Party upon the failure of the other Party to perform any
            material term, condition or covenant of this Agreement, which
            failure has not been cured within thirty (30) days of the date of
            written notice of such failure given by the other Party or, with
            respect to any failure to make any payment when due and payable
            hereunder, within five (5) Business Days of such notice of failure;
            or

      (b)   by a Party upon the other Party becoming insolvent or initiating
            (voluntarily or involuntarily) any bankruptcy proceeding.

8.4   EFFECT OF TERMINATION.

      (a)   The expiration or termination of this Agreement pursuant to the
            terms of this Article 8 or otherwise shall not relieve any of the
            Parties of any obligations

                                       23
<PAGE>

            accruing prior to such termination, and any such termination shall
            be without prejudice to the rights of either party against the other
            conferred on it by this Agreement. Neither party shall be entitled
            to any compensation whatsoever as a result of termination of this
            Agreement (but without limiting either party's damages for any
            breach of this Agreement). In addition, except as provided below,
            the provisions of Sections 2.2, 2.3, 2.4, 2.5, 3.2, 8.4, 9.3 and 9.4
            and Article 1, Article 6, Article 7 and Article 10 shall survive
            expiration or termination of this Agreement for any reason. Upon
            expiration or termination of this Agreement, (a) except as expressly
            permitted under this Agreement, each Party shall immediately cease
            use of the Confidential Information of the other Party (and if
            requested by the other Party, shall return or destroy, all tangible
            embodiments thereof); and (b) all amounts due hereunder shall be
            immediately due and payable. Notwithstanding anything to the
            contrary contained herein, upon any termination of this Agreement by
            GT pursuant to Section 8.3(a), the License granted pursuant to
            Section 2.2 shall automatically and immediately terminate, whether
            during or after the term of this Agreement. For the avoidance of
            doubt, the License shall be subject to termination upon written
            notice by GT in the event that Customer (or any assignee or
            transferee) fails to comply with, or otherwise breaches, any of the
            terms or conditions of (x) Section 2.2 (including any breach of any
            of Customer's obligations thereunder with respect to sublicensing,
            assignment and transfer), (y) Article 6, and/or (z) Section 10.8(b).

      (b)   The Parties agree that the license rights granted to each Party
            hereunder are rights in "intellectual property" within the scope of
            Section 101 (or its successors) of the United States Bankruptcy Code
            (the "Code"). Each Party, as a licensee of intellectual property
            rights hereunder, shall have and may fully exercise all rights
            available to a licensee under the Code, including under Section
            365(n) or its successors.

                                    ARTICLE 9
               REPRESENTATIONS AND WARRANTIES; PRODUCT WARRANTIES

            Subject to Section 9.2(b), GT hereby represents and warrants that
            each item of Equipment, upon Delivery, shall (A) be new and free
            from material defects in design, workmanship and materials (except
            for normal wear and tear on parts), and (B) conform to its
            respective Specifications, through the applicable Warranty Period;
            except that, for the avoidance of doubt, notwithstanding anything to
            the contrary in the Specifications or hereunder, the only
            representation or warranty provided with respect to any growth rate,
            shall be, subject to Section 9.2(b) and Section 4.5, that, during
            the Warranty Period, each Reactor shall have the capacity to yield
            at least the applicable Minimum Average Growth Rate. Customer's sole
            and exclusive remedy, and GT's sole liability, for any failure of
            any Equipment to comply with this Section 9.2(a) shall be solely as
            set forth in Section 9.2(c). Customer hereby agrees that the
            foregoing remedy shall be its sole and exclusive remedy and shall
            not be deemed to have, and Customer shall not assert that it has,
            failed its essential purpose.

      (b)   Exceptions to Warranties; Indemnity. Notwithstanding anything herein
            to the contrary, the warranties set forth in this Section 9.2, and
            the indemnity set forth in Section 7.1, shall not apply to, and GT
            shall have no obligation with respect to, (i) any non-conformities
            or other defects resulting from normal wear and tear or (ii) to any
            Equipment that is (A) installed, operated, used or maintained in any
            manner other than in accordance with the Documentation, the
            Specifications or any instructions provided by GT, (B) operated or
            used other than for its intended purpose, (C) subject to misuse,
            neglect or accident, (D) repaired, modified or in way altered in any
            respect other than by GT, or (E) combined with other equipment,
            materials or software, technology or other intellectual property not
            supplied or recommended or authorized in writing by GT.

      (c)   Remedies for Non-Compliance. Subject to Section 9.2(b), if any item
            of Equipment fails to comply with the warranty set forth in Section
            9.2(a) (after re-calculations as set forth in Section 4.5(c)) (and
            provided that none of the foregoing, is subject to any exception
            under Section 9.2(b), and provided further that Customer has
            complied with all of the conditions set forth in Section 4.5 and
            Customer notifies GT of any of the foregoing, then GT shall, at GT's
            sole option, repair or replace any such defective Equipment (and
            Customer acknowledges that such repair or replacement could take GT
            up to, for example, twelve (12) months depending upon the nature of
            the repair or replacement). GT shall bear all of its own costs and
            expenses incurred in connection with fulfilling its warranty
            obligations under this Section 9.2(c). Customer shall cooperate with
            GT and allow GT and its representatives reasonable access to
            Customer's site for the purposes of repairing Equipment or removing
            Equipment for repair or replacement, as determined by GT in its
            discretion. Repaired or replaced Equipment shall be shipped to
            Customer by GT by reasonable commercial means, at GT's cost. If
            requested by GT, Customer shall ship or deliver such item of
            Equipment to the facility designated by GT (provided that GT shall
            pay for and

                                       25
<PAGE>

            arrange the shipping or other transport of such item of Equipment).
            If GT, in its discretion, is not able to repair or replace such item
            of Equipment, then GT shall refund to Customer the total Unit Price
            for such item of Equipment, less straight line depreciation of such
            item of Equipment over a ten (10) year period. The foregoing shall
            be Customer's sole and exclusive remedy, and GT's sole liability,
            for any failure of any Equipment to comply with any warranties.
            Customer hereby agrees that the foregoing remedy shall not be deemed
            to have, and Customer shall not assert that it has, failed its
            essential purpose.

9.3   DISCLAIMERS. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET
      FORTH IN SECTION 9.2 (WHICH ARE EXCLUSIVE AND IN LIEU OF ALL OTHER
      REPRESENTATIONS AND WARRANTIES OF ANY KIND) GT MAKES NO OTHER WARRANTY,
      EXPRESS OR IMPLIED, WITH RESPECT TO THE EQUIPMENT OR OTHERWISE, AND
      EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER STATUTORY, EXPRESS OR IMPLIED,
      INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR

      INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
      PURPOSE, NON-INFRINGEMENT AND ALL REPRESENTATIONS OR WARRANTIES ARISING
      FROM COURSE OF DEALING OR USAGE OF TRADE.

9.4   LIMITATIONS OF LIABILITY. UNDER NO CIRCUMSTANCES WILL GT, OR ITS
      AFFILIATES OR ANY OF ITS OR THEIR DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS
      BE LIABLE TO CUSTOMER FOR ANY SPECIAL, INDIRECT, INCIDENTAL,
      CONSEQUENTIAL, SPECIAL, EXEMPLARY, PUNITIVE OR OTHER DAMAGES, OR ANY LOSS
      OF PROFITS OR REVENUES, OR ANY LOSS RESULTING FROM INTERRUPTION OF
      BUSINESS OR COST OF CUSTOMER'S LABOR, EVEN IF GT OR ITS AFFILIATES OR ANY
      OF ITS OR THEIR DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS HAVE BEEN ADVISED
      OF THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING ANY FAILURE OF
      ESSENTIAL PURPOSE OF ANY LIMITED REMEDY OF ANY KIND, UNDER ANY CONTRACT,
      TORT, NEGLIGENCE, STRICT LIABILITY OR ANY OTHER THEORY (AND INCLUDING
      UNDER ANY WARRANTY OR OTHERWISE), ARISING OUT OF OR RELATING IN ANY WAY TO

                                       26
<PAGE>

      TERMS OR CONDITIONS OF, THIS AGREEMENT). THE REMEDIES EXPRESSLY PROVIDED
      HEREIN ARE CUSTOMER'S SOLE AND EXCLUSIVE REMEDIES, WHETHER CLAIMS ARE
      BASED IN ANY CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR ANY OTHER
      THEORY (OR INCLUDING UNDER ANY WARRANTY OR OTHERWISE). TO THE EXTENT
      PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL GT'S OR ITS AFFILIATES OR
      ANY OF ITS OR THEIR DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS TOTAL
      COLLECTIVE LIABILITY ARISING OUT OF OR RELATING IN ANY WAY TO OR IN
      CONNECTION WITH THIS AGREEMENT OR ITS IMPLEMENTATION EXCEED THE AMOUNT OF
      THE PURCHASE PRICE PAID BY CUSTOMER TO GT FOR THE EQUIPMENT HEREUNDER.
      CUSTOMER ACKNOWLEDGES AND AGREES THAT THE EXCLUSIVE REMEDIES AND
      LIMITATIONS OF LIABILITIES SET FORTH HEREIN WERE BARGAINED FOR AND ARE
      ESSENTIAL TERMS OF THIS AGREEMENT AND THAT, BUT FOR SUCH EXCLUSIONS AND
      LIMITATIONS, THE PURCHASE PRICE WOULD BE HIGHER. NOTHING IN THIS AGREEMENT
      SHALL LIMIT OR EXCLUDE THE LIABILITY OF EITHER PARTY FOR DEATH OR PERSONAL
      INJURY RESULTING FROM ITS NEGLIGENCE OR FOR FRAUDULENT MISREPRESENTATION.

      third party in connection with a sale of all or substantially all of the
      assets to which this Agreement relates (whether by assignment, operation
      of law, by merger or otherwise), in each case shall not require the prior
      written consent of the other Party; provided, further however, that the
      assigning or transferring Party, as applicable, (x) notifies the other
      Party of such assignment or other transfer, and (y) the assignee or
      transferee (including any assignee or

                                       27
<PAGE>

      transferee consented to by the other Party in writing, as set forth
      above), as applicable, acknowledges and agrees in writing to the
      non-assigning, or non-transferring, as applicable, Party to be bound by
      the terms and conditions of this Agreement, and (z) with respect to any
      such assignment or other transfer by Customer to a subsidiary or other
      Affiliate (or any other assignment or other transfer consented to by GT in
      writing, as set forth above), prior to any such assignment or other
      transfer, such subsidiary or other Affiliate (or such other assignee or
      other transferee consented to in writing by GT (as set forth above)) shall
      open an irrevocable confirmed standby letter of credit in favor of, and
      which is acceptable to, GT (and which is consistent with the terms of
      Section 3.2(c)(iii)) in replacement of the irrevocable confirmed letter of
      credit in favor of GT opened by Customer in accordance with the terms of
      Section 3.2(c)(iii). Any attempt at assignment or other transfer (whether
      by assignment, operation of law, by merger or otherwise) in violation of
      this Section 10.2 (and/or Section 2.2) shall be null and void.
      Notwithstanding anything contained herein to the contrary, no assignment
      or other transfer (whether by assignment, operation of law, by merger or
      otherwise) of this Agreement shall be permitted if it would violate the
      terms of Section 10.8(b) or Section 2.2.

10.3  BINDING EFFECT. The terms and conditions of this Agreement shall be
      binding upon, and shall inure to the benefit of, the Parties hereto and
      their respective permitted successors and assigns.

10.4  NO THIRD PARTY BENEFICIARIES. Nothing in this Agreement, express or
      implied, is intended to or shall be construed to confer upon or give to
      any person or other entity, other than the Parties, any interests, rights,
      remedies or other benefits with respect to or in connection with any
      agreement or provision contained herein or contemplated hereby, and the
      provisions of the Contract (Third Party Rights) Act are hereby
      specifically excluded.

10.5  RELATIONSHIP OF PARTIES. The relationship hereby established between GT
      and Customer is solely that of supplier and customer. Each is an
      independent contractor engaged in the operation of its own respective
      business, and nothing in this Agreement shall be construed to create a
      partnership, agency, joint venture, pooling, franchise or
      employer-employee relationship between the Parties. Neither Party shall be
      responsible for the compensation, payroll-related taxes, workers'
      compensation, accident or health insurance or other benefits of employees
      of the other Party. Neither Party has the power or authority to act for,
      represent, or bind the other Party (or any of the other Party's
      Affiliates) in any manner.

10.6  FORCE MAJEURE. Neither Party shall be held responsible for any delay or
      failure to perform a obligation hereunder to the extent caused by fires,
      strikes, embargoes, government requirements, civil or military
      authorities, terrorism (or the threat thereof), acts of God or of the
      public enemy or any other causes beyond their reasonable control (each a
      "Force Majeure Event") provided, however, that this Section shall not
      relieve a party of its obligation to make payments as they become due
      hereunder. A Party shall

                                       28
<PAGE>

      promptly notify the other Party of the occurrence of a Force Majeure
      Event, the time for performance under this Agreement by the Party whose
      performance is affected by such Force Majeure Event shall be suspended
      during the continuance of such Force Majeure Event and thereafter extended
      for the period equal to that during which such Force Majeure Event
      continued. The Party whose performance is affected by a Force Majeure
      Event shall provide written notice to the other Party of such Force
      Majeure Event, specifying the nature and the expected duration of the
      Force Majeure Event, within fifteen (15) Business Days after the Party
      whose performance is affected becomes aware of such Force Majeure Event,
      and, to the extent reasonable, shall use its commercially reasonable
      efforts to mitigate the effects of the Force Majeure Event.

10.7  CHOICE OF LAW; JURISDICTION. This Agreement, the legal relations between
      the Parties and any related order shall be governed and interpreted,
      construed, and enforced in accordance with the laws of England,
      notwithstanding the choice of law rules of any jurisdiction. The
      Convention for the International Sale of Goods shall not apply to this
      Agreement and is hereby expressly disclaimed. SUBJECT TO SECTIONS 10.9 AND
      10.10, IF A PARTY BRINGS A JUDICIAL PROCEEDING THAT IS PERMITTED BY THIS
      AGREEMENT TO ENFORCE ANY DECISION OF A MAJORITY OF THE ARBITRATORS TO
      SECTION 10.9 OR TO SEEK INJUNCTIVE OR OTHER EQUITABLE RELIEF PURSUANT TO
      SECTION 10.10 (A "PERMITTED JUDICIAL PROCEEDING") IN ANY COURT OF
      COMPETENT JURISDICTION LOCATED IN LONDON, ENGLAND, THE OTHER PARTY HEREBY
      IRREVOCABLY CONSENTS TO THE JURISDICTION OF, AND VENUE IN, ANY SUCH COURT
      OF COMPETENT JURISDICTION LOCATED IN LONDON, ENGLAND AND SHALL NOT CONTEST
      OR SEEK TO CHANGE SUCH VENUE. IN ADDITION, IF GT BRINGS A PERMITTED
      JUDICIAL PROCEEDING IN ANY COURT OF COMPETENT JURISDICTION LOCATED IN
      CHINA, CUSTOMER HEREBY IRREVOCABLY CONSENTS TO THE JURISDICTION OF, AND
      VENUE IN, ANY SUCH COURT OF COMPETENT JURISDICTION LOCATED IN HONG KONG OR
      OTHERWISE IN CHINA AND SHALL NOT CONTEST OR SEEK TO CHANGE SUCH VENUE.
      SUBJECT TO SECTIONS 10.9 AND 10.10, THE FOREGOING SHALL NOT, HOWEVER,
      LIMIT A PARTY FROM BRINGING A PERMITTED JUDICIAL PROCEEDING IN ANY OTHER
      COURT OF COMPETENT JURISDICTION, REGARDLESS OF WHETHER WITHIN OR OUTSIDE
      OF ENGLAND. EACH PARTY CONSENTS TO SERVICE OF PROCESS BY ANY METHOD OF
      NOTICE (EXCEPT EMAIL) SPECIFIED IN SECTION 10.11 (TO THE EXTENT PERMITTED
      BY APPLICABLE LAW).

10.8  COMPLIANCE WITH LAWS.

      (a)   Customer shall, and shall cause its Affiliates and each of their
            respective directors, officers, employees, consultants, contractors,
            agents and owners to, comply with all applicable laws and
            regulations relating to this Agreement and the performance of their
            obligations and exercise of their rights hereunder, including

                                       29
<PAGE>

            all applicable export control laws and laws prohibiting corrupt
            practices (e.g., United States Foreign Corrupt Practices Act).

      (b)   Without limiting Section 10.8(a), notwithstanding anything herein to
            the contrary, Customer shall not, and shall cause its Affiliates,
            and each of their respective directors, officers, employees,
            consultants, contractors, agents and owners, to not, use, or export,
            assign or otherwise transfer (whether by assignment, sale, operation
            of law or otherwise) to any person, entity or country, this
            Agreement or any rights or obligations hereunder, any of the
            Equipment or any of GT's Confidential Information, or exercise any
            rights hereunder, which, if done by GT directly, would violate any
            laws of the United States or any other applicable laws and
            regulations (including any export control laws or regulations) or
            which would otherwise result in GT being in violation of any such
            laws or regulations.

10.9  DISPUTE RESOLUTION.

      (a)   NEGOTIATION BETWEEN PARTIES. The Parties agree to negotiate in good
            faith to resolve any dispute, controversy or difference between them
            arising out of, in connection with or relating to, this Agreement
            (any such dispute, controversy or difference, a "Dispute"), and for
            such purpose shall nominate one senior officer as its
            representative. These representatives shall meet in person and shall
            attempt in good faith to resolve the Dispute, provided that if such
            senior officers are unable or otherwise do not meet, or the Dispute
            is not otherwise resolved by the Parties, within thirty (30) days of
            the written meeting request, either Party may thereafter commence
            arbitration proceedings in accordance with Section 10.9(b) below.
            The Parties agree that during the pendency of any Dispute, the
            Parties shall continue to perform their respective obligations under
            this Agreement to the extent that such performance is not the
            subject of the Dispute. Notwithstanding the foregoing, for the
            avoidance of doubt, and without limiting any of GT's available
            rights or remedies, if the Dispute relates to Customer's failure to
            pay GT amounts owed to GT, GT may proceed directly to arbitration at
            any time upon ten (10) Business Days notice to Customer, and shall
            not be obligated to continue to perform its obligations under this
            Agreement until Customer remedies such failure to make payment by
            paying GT in full all such overdue amounts, together with any
            interest payable by Customer to GT with respect thereto pursuant to
            Section 3.23.2(b).

      (b)   ARBITRATION. Subject to Section 10.10, any Dispute not resolved
            under Section 10.9(a) shall be resolved through arbitration pursuant
            to this Section 10.9(b). The Parties hereby waive any right to
            institute a court or other dispute resolution proceeding and
            acknowledge that arbitration in accordance with this Section 10.9(b)
            is the sole and exclusive means of resolving any Dispute hereunder
            or relating hereto, except that the Parties may at any time,
            initiate other proceedings as provided in Section 10.10. Subject to
            Section 10.10, all Disputes shall be finally settled by arbitration
            in accordance with the auspices of the

                                       30
<PAGE>

      International Institute for Conflict Prevention & Resolution ("CPR")
      pursuant to the CPR Rules for Non-Administered Arbitration of
      International Disputes and shall, unless otherwise mutually agreed by the
      Parties, be held in London, England before by an arbitration board
      consisting of three (3) arbitrators. Each of the Customer and GT shall
      select one arbitrator within thirty (30) days after giving or receiving a
      demand for arbitration. Such arbitrators shall be freely selected, and
      neither Customer nor GT shall be limited in their selection to any
      prescribed list. The two (2) arbitrators appointed by the Parties shall
      appoint the third arbitrator who shall serve as the chairman of the
      arbitration board. If either the Customer or GT does not appoint an
      arbitrator who has consented to participate within thirty (30) days after
      selection of the first arbitrator, the relevant appointment shall be made
      in accordance with the CPR Rules for Non-Administered Arbitration of
      International Disputes. The arbitration proceedings shall be conducted in
      English. The arbitration tribunal shall apply the CPR Rules for
      Non-Administered Arbitration of International Disputes in effect at the
      time of the arbitration. However, if such rules are in conflict with the
      provisions of this Section 10.9(b) including the provisions concerning the
      appointment of arbitrators, the provisions of this Section 10.9(b) shall
      prevail. The arbitrators shall decide any Dispute submitted by the Parties
      to the arbitration in accordance with the substantive law of England. In
      making their award, the arbitrators shall have the right to award
      reasonable attorney's fees as they deem just and appropriate under the
      circumstances (subject to the terms and conditions of this Agreement). The
      award shall be issued within sixty (60) days of the constitution of the
      arbitration tribunal, provided, however, that the arbitration tribunal
      shall, upon a finding that it is impracticable to meet such deadline
      consistent with its primary obligation justly to determine the controversy
      before it, have discretion to extend or alter such deadline to the extent
      necessary to prevent injustice or preserve the enforceability of its
      award. The award of the arbitration tribunal shall be final and binding
      upon the disputing Parties, and any Party may apply to a court of
      competent jurisdiction for enforcement of such award. For the avoidance of
      doubt, the arbitrators shall not have the authority to award punitive or
      special damages (including any lost profits) and awards shall be
      consistent with the limitations on liability set out in Section 9.4 and
      shall be made in accordance with, and subject to, the other terms and
      conditions of this Agreement. In the absence of a contrary ruling by the
      arbitrators, each Party shall pay its own costs and fees in connection
      with the arbitration. Each Party shall cooperate with the other Party and
      use its respective reasonable commercial efforts to take such actions
      reasonably required to facilitate the prompt enforcement in the PRC or in
      any other jurisdiction, as applicable, of any arbitration award made by
      the tribunal in accordance with the terms and conditions of this
      Agreement.

10.10 INJUNCTIVE RELIEF; SPECIFIC PERFORMANCE. The Parties hereto acknowledge
      and agree that a breach of the terms of this Agreement could give rise to
      irreparable harm for which money damages would not be an adequate remedy
      and accordingly the Parties agree that, in addition to any other remedies,
      and notwithstanding anything contained in this

                                       31
<PAGE>

      Agreement, each Party shall be entitled to seek preliminary or injunctive
      relief and to enforce the terms of this Agreement by a decree of specific
      performance. Without limiting the generality of the foregoing, Customer
      hereby acknowledges and agrees that the GT Confidential Information has
      substantial business value to GT, provides a significant competitive
      advantage to GT and that any improper use or disclosure of any GT
      Confidential Information would materially impair the business value of
      such GT Confidential Information and irreparably harm GT's business.
      Therefore, Customer hereby agrees that, notwithstanding anything contained
      in this Agreement, GT shall be entitled to preliminary or injunctive
      relief and to specific enforcement of this Agreement in connection with
      any breach of the terms of Section 2.2, Article 6 and/or Section 10.8(b),
      in each case without posting of any bond or other security.

10.11 NOTICES. Any consent, agreement, approval or notice required or permitted
      to be given or made under this Agreement by one of the Parties hereto to
      other Party shall be in writing and in English and shall be delivered in
      person or by Federal Express (or other recognized international courier
      service requiring signature upon receipt) or by facsimile or email (as
      evidenced by a paper copy of such email). Such notice shall be deemed
      effective upon receipt or, in the case of facsimile or email, upon written
      confirmation of receipt by the other Party (such confirmation to be
      transmitted in person, by email or international courier as provided
      above). For purposes of notice, the addresses of the Parties shall be as

      its obligations, agreements or conditions hereunder may only be waived in

      original intent of such provision.

10.16 ENTIRE AGREEMENT. The exhibits and any other attachments to this
      Agreement, and all terms and conditions contained therein, are hereby
      incorporated by reference provided that, in the event of a conflict
      between any term or condition of this Agreement and any term or condition

            feedgas to the Reactor, and the level of contamination of the seed
            filaments.

      2.    The level of surface metals contamination is determined by how the
            polysilicon is processed following removal from the Reactor, and the
            cleanliness of the room where the polysilicon is handled.
