          3.2. HOKU
            intends to manufacture the Products at its Facility; however, notwithstanding
            anything to the contrary herein, HOKU may deliver to CUSTOMER Products
            that are
            manufactured by a third party other than HOKU, (the “Alternative
            Products”).
            The
            Alternative Products shall conform to the warranties of HOKU to CUSTOMER
            hereunder, and the quality, price, delivery and any other terms and conditions
            of the Alternative Products shall be no less favorable than the terms
            and
            conditions
            set
            forth in this Agreement. Delivery
            of the Alternative Products shall not release or mitigate HOKU’s liabilities and
            obligations hereunder except that delivery of the Alternative Products
            is deemed
            to be delivery of Products, and CUSTOMER shall have the same rights and
            HOKU
            shall have the same obligations as set forth hereunder with respect to
            any
            Alternative Products. HOKU shall notify CUSTOMER in writing prior to
            the
            delivery of Alternative Products.

           

          3.3. Except
            in
            the case of a force majeure pursuant to Section 12 below, if at any time
            after
            [*], HOKU does not supply any Products pursuant to Section 0
            or
0
            within
            [*] days of the scheduled delivery date, HOKU will provide CUSTOMER with
            a
            purchase price adjustment. Such purchase price adjustment shall be [*]
            percent
            ([*]%) of the value of the respective delayed Products for each week
            or part
            thereof that the Product shipment (or part thereof) is delayed beyond
            the [*]
            day grace period. Any
            purchase price adjustment as a result of this Section 0
            will be
            paid by HOKU at the end of the term of the applicable calendar quarter.
            In lieu of making a cash payment to CUSTOMER pursuant to this Section
            0,
            HOKU
            may,
            at its option, pay for such purchase price adjustment in the form of
            a credit
            issued for future shipments of Products.
            Notwithstanding anything to the contrary, the maximum amount of such
            purchase
            price reduction is limited to [*] percent ([*]%) of the value of the
            respective
            delayed Products. Monthly shipments which are delayed beyond [*] days
            shall be
            deemed to constitute a material breach of this Agreement pursuant to
            Section
0
            below.
            Notwithstanding the foregoing, if CUSTOMER fails to make a payment to
            HOKU
            within the [*] period set forth in Section 0
            below,
            HOKU shall not be required to supply any Product to CUSTOMER until HOKU
            has
            received the past due amount including any interest payable thereon pursuant
            to
            this Agreement. For the avoidance of doubt, CUSTOMER’s right to reduce the
            purchase price pursuant to this Section 0
            shall
            not apply if HOKU is not fulfilling its supply obligations for this
            reason.

           

          4. Shipping
            & Delivery. 

           

          4.1. Except

            with
            a shipment schedule that will be provided by HOKU each Year under this
            Agreement
            (the “Shipment
            Schedule”)
            no
            later than sixty (60) days prior to the applicable Year. The Shipment
            Schedule
            shall provide for approximately equal monthly shipments in amounts not
            less than
            the Minimum Monthly Quantity that adds up to the Minimum Annual Quantity
            of
            Products. 

           

          4.2. HOKU
            will
            use commercially reasonable efforts to make available to CUSTOMER its
            first
            shipment of Products on or before [*].

              Notwithstanding the foregoing, (A) HOKU shall have no obligation to
              ship to
              CUSTOMER any Products that HOKU intends to reserve for its inventory;

              payment of Twenty Two Million U.S. Dollars (US$22,000,000) as an advance
              payment
              for Products to be delivered under this Agreement, via wire transfer
              of
              immediately available funds (the “Initial
              Deposit”);
              provided, however, that in the event applicable law or the requirements
              of the
              Rules Governing the Listing of Securities on The Stock Exchange of
              Hong Kong
              Limited shall require the approval of this Agreement at an Extraordinary

              Meeting of CUSTOMER’s shareholders, then CUSTOMER may delay such payment of the

              is
              not obtained, and if HOKU exercises its right to terminate this Agreement
              pursuant to Section 0,
              then
              CUSTOMER shall be obligated to pay HOKU a break-up fee equal to [*].

                letter of credit in substantially the form of Appendix

                attached
                hereto (the “Letter
                of Credit”)
                together with such additional restrictions consistent with this Agreement
                in
                substitution of the terms currently set forth on Appendix 3, and
                reasonable
                modifications proposed by the issuing bank, in the amount of the Main Deposit.
                The Letter of Credit shall be issued to HOKU by a bank which has
                a credit rating
                that is acceptable to HOKU in its sole discretion, or such other

                approved by HOKU and CUSTOMER (the “Issuing
                Bank”).
                The
                Letter of Credit shall be issued in US Dollars for the full amount
                of the Main
                Deposit, and shall be freely assignable by HOKU in connection with

                2010, but shall be renewable for an additional one-year period if
                the entire
                amount of the Main Deposit has not been paid to HOKU as of such expiration
                date.

               

              5.6.  HOKU
                shall invoice CUSTOMER at or after the time of each shipment of Products
                to
                CUSTOMER. Taxes, customs and duties, if any, will be identified as
                separate
                items on HOKU invoices. All invoices shall be sent to CUSTOMER’s address as
                provided herein. Payment terms for all invoiced amounts shall be
                [*] days from
                date of shipment. All payments shall be made in U.S. Dollars. Unless
                HOKU is
                entitled to retain the Total Deposit as liquidated damages pursuant
                to Section
0
                below,
shipments
                to CUSTOMER shall be credited against the Total Deposit according
                to the schedule of credits in Appendix 1 until there are no Funds
                Remaining on
                the Deposit (as defined in Section 0). 

               

              5.7. The
                prices for the Products do not include any excise, sales, use, import,
                export or
                other similar taxes, such taxes will not include income taxes or
                similar taxes,
                which taxes will be invoiced to and paid by CUSTOMER, provided that
                CUSTOMER is
                legally or contractually obliged to pay such taxes. CUSTOMER shall
                be
                responsible for all transportation charges, duties or charges, liabilities
                and
                risks for shipping and handling (and hereby indemnifies HOKU for
                such costs,
                liabilities and risks); thus, the price for the Products shall not
                include any
                such charges.

               

              5.8. Late
                payments and outstanding balances shall accrue interest at the lesser
                of [*] per
                annum or the maximum allowed by law. 

               

              6. Security
                Interest.

               

              6.1. Subject
                to receipt of the Initial Deposit HOKU hereby grants to CUSTOMER
                a security
                interest to secure the repayment by HOKU to CUSTOMER of the Total
                Deposit
                following any of the events set forth in Section 0
                below,
                which shall be subordinated in accordance with Section 0
                below,
                in all of the tangible and intangible assets related to HOKU’s polysilicon
                business (the “Collateral”).
                

               

              6.2. CUSTOMER
                acknowledges and agrees that the security interests and liens in
                the Collateral
                will not be first priority security interests, will be expressly
                subordinated to
                HOKU’s third-party lenders (the “Senior
                Lenders”)
                that
                provide debt financing for the construction of any HOKU Facility,
                and may be
                subordinated as a matter of law to other security interests, and
                to security
                interests that are created and perfected prior to the security interest
                granted
                to CUSTOMER hereby. CUSTOMER shall enter into subordination agreements
                with the
                Senior Lenders on terms and conditions reasonably acceptable to the
                Senior

                6.3. In
                  addition, CUSTOMER shall enter into collateral, intercreditor and
                  other
                  agreements (the “Collateral
                  Agreements”)
                  with
                  HOKU’s Senior Lenders, and with SANYO Electric Co., Ltd., Suntech Power
                  Holding
                  Co., Ltd., Global Expertise Wafer Division, Ltd., Solarfun Power
                  Hong Kong
                  Limited, Jiangxi Kinko Energy Co., Ltd., and Tianwei New Energy
                  (Chengdu) Wafer
                  Co., Ltd and HOKU’s other customers who provide prepayments for Products
                  (collectively, “HOKU’s
                  Other Customers”),
                  as
                  may be reasonably necessary to ensure that the security interest
                  granted hereby
                  is pari passu with the security interests that may be granted to
                  HOKU’s Other
                  Customers. CUSTOMER may not unreasonably refuse to sign any such
                  Collateral
                  Agreement, provided that such Collateral Agreement grants CUSTOMER
                  a pari passu
                  priority with respect to HOKU’s Other Customers, and is expressly subordinated
                  to the Senior Lenders. 

                 

                6.4. The
                  security interest granted hereby shall continue so long as HOKU
                  continues to
                  maintain any amount of the Total Deposit, and only to the extent
                  of such
                  remaining amount of the Total Deposit being held by HOKU, which
                  has not been
                  credited against the shipment of Products pursuant to this Agreement,
                  or
                  otherwise repaid to CUSTOMER. Notwithstanding anything to the contrary
                  contained
                  in this Agreement, the Collateral consisting of real property shall
                  secure only
                  the obligations of HOKU to refund any portion of the Total Deposit
                  to CUSTOMER
                  in accordance with the terms of this Agreement. When the Total
                  Deposit is no
                  longer held by HOKU, CUSTOMER will sign such documents as are necessary
                  to
                  release its security interests.

                 

                6.5. HOKU
                  and
                  CUSTOMER each agree to act in good faith to execute and deliver
                  any additional
                  document or documents that may be required in furtherance of the
                  foregoing
                  provisions of this Section 0,
                  including the Collateral Agreements. Neither HOKU nor CUSTOMER
                  may unreasonably
                  refuse to sign any such document.

                 

                7. Product
                  Quality Guarantee.

                 

                7.1. HOKU
                  warrants to CUSTOMER that the Products shall meet the Product Specifications.
                  For each shipment, this warranty shall survive for [*] days after
                  the applicable
                  shipment date (the “Warranty
                  Period”).
                  Upon
                  release of the Products to a common carrier or freight forwarder,
                  FOB origin
                  (INCOTERMS 2000), HOKU warrants that the Products shall be free
                  of all liens,
                  mortgages, encumbrances, security interests or other claims or
                  rights. HOKU
                  will, upon prompt notification and compliance with HOKU’s instructions, refund
                  or replace, at CUSTOMER’s sole option, any Product which does not meet the
                  Product Specifications, and CUSTOMER shall comply with the inspection
                  and return
                  goods policy described in Section 0
                  below
                  with respect to such Products. No employee, agent or representative
                  of HOKU has
                  the authority to bind HOKU to any oral representation or warranty
                  concerning the
                  Products. Any oral representation or warranty made prior to the
                  purchase of any
                  Product and not set forth in writing and signed by a duly authorized
                  officer of
                  HOKU shall not be enforceable by CUSTOMER. HOKU makes no warranty
                  and shall have
                  no obligation with respect to damage caused by or resulting from
                  accident,
                  misuse, neglect or unauthorized alterations to the Products.

                    EXPRESSLY DISCLAIMS ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED
                    OR STATUTORY,
                    INCLUDING THE WARRANTIES OF MERCHANTABILITY, AND FITNESS FOR
                    A PARTICULAR
                    PURPOSE. Except as otherwise provided in Section 0
                    below,
                    HOKU’s sole responsibility and CUSTOMER’s exclusive remedy for any claim arising
                    out of the purchase of any Product is a refund or replacement,
                    as described
                    above. In no event shall HOKU’s liability exceed the purchase price paid
                    therefore; nor shall HOKU be liable for any claims, losses or
                    damages of any
                    individual or entity or for lost profits or any special, indirect,
                    incidental,
                    consequential, or exemplary damages, howsoever arising, even
                    if HOKU has been
                    advised of the possibility of such damages.

                   

                  7.3. HOKU
                    shall, at its own expense, indemnify and hold CUSTOMER and its
                    Affiliates
                    harmless from and against any expense or loss resulting from
                    any actual or
                    alleged infringement of any patent, trademark, trade secret,
                    copyright, mask
                    work or other intellectual property related to the Products,
                    and shall defend at
                    its own expense, including attorneys fees, any suit brought against
                    CUSTOMER or
                    CUSTOMER’s Affiliates alleging any such infringement. CUSTOMER agrees
                    that: (i)
                    CUSTOMER shall give HOKU prompt notice in writing of any such
                    suit; (ii) if HOKU
                    provides evidence reasonably satisfactory to CUSTOMER of HOKU’s financial
                    ability to defend the matter vigorously and pay any reasonably
                    foreseeable
                    damages, CUSTOMER shall permit HOKU, through counsel of HOKU’s choice, to answer
                    the charge of infringement and defend such suit (but CUSTOMER,
                    or CUSTOMER’s
                    Affiliate may be represented by counsel and participate in the
                    defense at its
                    own expense); and (iii) CUSTOMER shall give HOKU all needed information,
                    assistance, and authority, at HOKU’s expense, to enable HOKU to defend such
                    suit. In case of a final award of damages in any such suit HOKU
                    shall pay such
                    award, but shall not be responsible for any settlement made without
                    its prior
                    consent. Except as otherwise expressly set forth herein, HOKU
                    disclaims any
                    obligation to defend or indemnify CUSTOMER, its officers, agents,
                    or employees,
                    from any losses, damages, liabilities, costs or expenses which
                    may arise out of
                    the acts of omissions of HOKU.

                    and Return Goods Policy.

                   

                  8.1. An
                    inspection of appearance of each shipment of Product shall be
                    made by CUSTOMER
                    in accordance with sound business practice upon the delivery
                    of the Product, and
                    in no case later than [*]
                    after
                    delivery at CUSTOMER’s factory. CUSTOMER shall inform HOKU promptly, and in no
                    case later than [*]
                    after
                    delivery of Product, in case of any obvious damages or other
                    obvious defects to
                    the Product which CUSTOMER discovers under the inspection of
                    appearance. 

                   

                  8.2. CUSTOMER
                    shall perform final inspection of the Product upon introducing
                    the Product into
                    CUSTOMER’s production process. Such inspection shall take place during
                    the
                    Warranty Period. If the Product does not meet the Product Specifications,
                    CUSTOMER shall notify HOKU in writing without undue delay after
                    the inspection
                    and, together with the notification, submit documentary evidence
                    of the result
                    of the final inspection whereupon HOKU shall have the right to
                    undertake its own
                    inspection prior to any return of the Products pursuant to Section
0
                    below.

                   

                  8.3. Products
                    may be returned to HOKU within the later of (a) [*] after discovery
                    of a defect
                    consistent with Sections 0
                    and
0
                    above;
                    and (b) [*] after HOKU completes its inspection and confirms
                    the defect pursuant
                    to Section 0
                    above,
                    for replacement or a refund including all return shipment expenses.
                    To assure
                    prompt handling, HOKU shall provide CUSTOMER a return goods authorization
                    number
                    within 48 hours of CUSTOMER’s request. Provided that HOKU communicates this
                    number to CUSTOMER within such timeframe, CUSTOMER will reference
                    this number on
                    return shipping documents. Returns made without the authorization
                    number
                    provided by HOKU in accordance with the foregoing may be subject
                    to HOKU’s
                    reasonable charges due to HOKU’s additional handling costs. HOKU reserves the
                    right to reverse any credit issued to CUSTOMER if, upon return,
                    such Product is
                    determined by an Independent Expert not to be defective.
                    The
                    conclusion of the Independent Expert shall be final, binding
                    and non-appealable
                    in respect of the conformity of the Products to the warranties
                    set forth in
                    Section 0
                    above.
                    The fees and expenses of the Independent Expert shall be paid
                    solely by the
                    party that does not succeed in the dispute.

                    9.1. The
                      term
                      of this Agreement shall begin on the Effective Date and shall

                      CUSTOMER’s failure to make payment to HOKU pursuant to this Agreement.
                      In the

                      hereof,
                      termination by HOKU shall require the issuance of a written

                      which occurs on
                      multiple occasions;

                      against the other Party; provided, that for an involuntary
                      bankruptcy or
                      insolvency proceeding, the Party subject to the proceeding
                      shall have sixty (60)

                          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-outs and other
                          events beyond its reasonable control, provided, however,
                          that the non-performing
                          Party shall not be so excused to the extent such default
                          or delay is
                          attributable to such non-performing Party failing to use
                          reasonable efforts to
                          prevent or such non-performing Party causing such default
                          or delay, and such
                          default or delay could not reasonably be circumvented by
                          the non-performing
                          Party through the use of alternate sources, workaround
                          plans or other means.
                          Notwithstanding the foregoing, a strike, lock-out or other
                          labor dispute
                          involving a Party (or, in the case of Supplier, a subcontractor
                          or supplier) and
                          its own personnel will not excuse such Party from performing
                          its obligations
                          hereunder. In such event, the non-performing Party will
                          be excused from further
                          performance or observance of the obligation(s) so affected
                          for as long as such
                          circumstances prevail and such Party continues to use commercially
                          reasonable
                          efforts to recommence performance or observance whenever
                          and to whatever extent
                          without delay. If such failure or delay occurs, the affected
                          Party (i.e. the
                          Party that is unable to perform) 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 conditions of
                          Force Majeure apply for
                          a period of more than two (2) consecutive calendar months,
                          the non-affected
                          Party shall be entitled to terminate this Agreement upon
                          written notice to the
                          other Party.

                            (i) to obtain
                            favorable treatment in securing business from CUSTOMER,

                            to scrupulously comply
                            with the FCPA and to adopt appropriate and reasonable
                            practices and procedures

                            nor to HOKU’s
                            knowledge, any other authorized person or entity associated

                          13.2. This
                            Agreement shall be construed under and governed by the
                            laws of the State of
                            California, U.S.A. 

                           

                          13.3. Upon
                            notice from one Party to the other of a dispute hereunder,
                            the Parties agree to
                            hold a meeting within thirty (30) days of receipt of
                            such notice with at least
                            one (1) representative from each Party who has decision-making
                            authority for
                            such company. At this meeting, the Parties will attempt
                            to resolve the dispute
                            in good faith. If, after the meeting, the dispute has
                            not been resolved, only
                            then may a Party resort to litigation. Any proceeding
                            to enforce or to resolve
                            disputes relating to this Agreement shall be brought
                            in California, USA. In any
                            such proceeding, neither Party shall assert that such
                            a court lacks jurisdiction
                            over it or the subject matter of the proceeding.

                            13.4. HOKU
                              may
                              assign its rights under this Agreement to any collateral
                              agent as collateral
                              security for HOKU’s secured obligations in connection with the financing

                              Facility, without the consent of CUSTOMER. Except as
                              stated in the previous
                              sentence, neither HOKU nor CUSTOMER may assign this
                              Agreement to a third party
                              without the prior written consent of the other Party,

                              unreasonably withheld. Notwithstanding the foregoing,

                              Agreement by either Party in connection with a merger,

          3. Supply
            Obligations.

            Shipment Date at least the Minimum Annual Quantity of Product in approximately
            equal monthly shipments pursuant to Section 4.1 below; provided however,
            that if
            HOKU fails to deliver a monthly shipment, then HOKU may deliver any deficiency
            within [*] days without breaching this section or incurring any purchase
            price
            adjustment (pursuant to Section 3.3
            below).
            The foregoing [*] day grace period shall not apply to the first shipment
            that is
            scheduled for April 30, 2010. Only shipments in excess of each scheduled
            monthly
            shipment pursuant to the Shipment Schedule (as defined in Section 4.1
            below)
            will be considered as making up a quantity deficiency as stated above.
            Notwithstanding the preceding sentence, HOKU shall promptly inform TIANWEI
            of
            any occurrence which will, or may be expected to, result in material
            delay of
            the shipment date or quantity of any scheduled monthly shipment set forth
            in the
            Shipment Schedule, or any other material deviations from the Shipment
            Schedule.
            HOKU shall use all commercially reasonable efforts to make complete delivery
            of
            Products scheduled for monthly shipment pursuant to the Shipment Schedule
            or, if
            later, as soon as commercially practicable. In the event that HOKU fails
            to
            deliver Products in accordance with the Shipment Schedule, TIANWEI may
            cause
            HOKU at HOKU’s own shipping responsibility, cost and expense to deliver Products
            to the locations designated by TIANWEI by rail or ocean cargo vessel.
            At any
            time during the term of this Agreement, HOKU may ship to TIANWEI up to
            the full
            cumulative balance of Minimum Annual Quantity of Product to be shipped
            through
            the end of this Contract (an “Excess
            Shipment”)
            with
            TIANWEI’s written consent. This shipment will be credited against each
            subsequent Minimum Annual Quantity of Product. For example, if the Minimum
            Annual Quantity of Product for a given Year is [*] metric tons, and if
            HOKU
            delivers [*] metric tons in January, then the next shipment of [*] metric
            tons
            is not required until the following Year.

                  3.2. HOKU
                    intends to manufacture the Products at its Facility; however,
                    notwithstanding
                    anything to the contrary herein, HOKU may deliver to TIANWEI
                    Products that are
                    manufactured by a third party other than HOKU (“Third
                    Party Products”),
                    where
                    HOKU is acting only as a reseller or distributor of such Products;
                    and provided
                    that the Products meet the Product Specifications and price set
                    forth in this
                    Agreement; and, provided further, that HOKU shall clearly label
                    all Third Party
                    Products and shall remain primarily liable for the acts and omissions
                    of such
                    third party producer in failing to meet the Quality Specifications.
                    HOKU shall
                    notify TIANWEI in writing prior to the delivery of Third Party
                    Products. 

                   

                  3.3. Except
                    in
                    the case of a force majeure pursuant to Section 12
                    below,
                    if HOKU does not supply any Products pursuant to Section 3.1
                    or
3.2
                    within
                    [*] days of the scheduled delivery date, HOKU will provide TIANWEI
                    with a
                    purchase price adjustment. Such purchase price adjustment shall
                    be [*] percent
                    ([*]%) of the value of the respective delayed Products for each
                    week or part
                    thereof that the Product shipment (or part thereof) is delayed
                    beyond the [*]
                    day grace period. Any
                    purchase price adjustment as a result of this Section 3.3
                    will be
                    immediately creditable by HOKU to the future invoiced price of
                    the Products to
                    be paid by TIANWEI commencing upon the date on which the purchase
                    price
                    reduction becomes due.
                    In lieu
                    of making a cash payment to TIANWEI pursuant to this Section
3.3,
                    HOKU
                    may,
                    at its option, pay for such purchase price adjustment in the
                    form of a credit
                    issued for future shipments of Products.
                    Notwithstanding anything to the contrary, the maximum amount
                    of such purchase
                    price adjustment shall not exceed [*] percent [*] of the value
                    of the respective
                    delayed Products. Monthly shipments which are delayed beyond
                    [*] days shall be
                    deemed to constitute a material breach of this Agreement pursuant
                    to Section
9.2.1
                    below.
                    Notwithstanding the foregoing, if TIANWEI fails to make a payment
                    to HOKU within
                    the [*] period set forth in Section 5.5
                    below,
                    HOKU shall not be required to supply any Product to TIANWEI until
                    HOKU has
                    received the past due amount including any interest payable thereon
                    pursuant to
                    this Agreement. For the avoidance of doubt, TIANWEI’s right to reduce the
                    purchase price pursuant to this Section 3.3
                    shall
                    not apply if HOKU is not fulfilling its supply obligations for
                    this
                    reason. 

                   

                  3.4. HOKU
                    hereby covenants and agrees that during the term of this Agreement,
                    and provided
                    that TIANWEI is not in breach of any material term of this Agreement,
                    including,
                    without limitation, its payment obligations hereunder, HOKU shall
                    not ship any
                    Products to any third party that is not one of HOKU’s Other Customers (e.g.,
                    spot market sales), until HOKU has satisfied its delivery obligations
                    to TIANWEI
                    pursuant to Section 3.1
                    of this
                    Agreement.
