 2.2 Quantity and Price. 
 (a) Target Purchase Quantities and Minimum Purchase Quantities. Each Contract Year, as set forth below in this Section 2.2(a),
Gintech agrees to purchase from MEMC, over the course of the Contract Year, a target quantity of Wafers (such yearly target purchase quantity commitments, measured in megawatts, the “Yearly Target Quantity”), at the prices set forth
on Attachment B hereto. Each Contract Year, as set forth below in this Section 2.2(a), MEMC agrees to supply Gintech, over the course of the Contract Year, with the Yearly Target Quantity per Contract Year, at the prices set forth on
Attachment B hereto, which Yearly Target Quantity will not fall below the Yearly Minimum Quantities (as such term is defined in Section 2.2(a)(i) below for Contract Years one through five and in Section 2.2(a)(ii) below for Contract
Years six through eleven). 
 (i ) For Contract Years one through five, the minimum quantities to be purchased by Gintech
(such quantities, the “Yearly Minimum Quantities”) shall be equal to the greater of (A) 100% of the yearly minimum quantities set forth on Attachment B hereto and (B) approximately [XXXX]% of Gintech’s
then current solar wafer demand (measured in Watts), provided that MEMC can accommodate [XXXX]% of Gintech’s actual then current solar wafer demand (as part of and pursuant to the rolling forecast process of Section 2.2(e)
hereof). For Contract Years one through five, MEMC shall be obligated to supply Gintech quantities only up to [XXXX]% of the Yearly Target Quantities set forth on Attachment B hereto for such Contract Year, unless MEMC has been given
at least three (3) years advance notice of Gintech’s request for quantities in excess of [XXXX]% of the Yearly Target Quantities in such years, and MEMC has agreed to supply such quantities. 
 (ii) For Contract Years six through eleven, no later than the first day of Contract Year three (January 1, 2009), the Parties agree to
commence a review to determine the exact quantities to be purchased and supplied for Contract Years six through eleven. Notwithstanding the foregoing, for Contract Years six through eleven, the minimum quantities to be purchased by Gintech (again,
for such Contract Years, such quantities, the “Yearly Minimum Quantities”) shall be equal to the greater of (A) 100% of the Yearly Minimum Quantities set forth on Attachment B hereto and (B) approximately
[XXXX]% of Gintech’s then current solar wafer demand (measured in Watts), provided that MEMC can accommodate [XXXX]% of Gintech’s actual then current solar wafer demand (as part of and pursuant to the rolling forecast
process of Section 2.2(e) hereof). For Contract Years six through eleven, MEMC shall be obligated to supply Gintech quantities only up to 100% of the Yearly Minimum Quantities set forth on Attachment B hereto for such Contract Years,
unless MEMC has been given at least three (3) years advance notice of Gintech’s request for quantities in excess of 100% of the Yearly Minimum Quantities for such years, in which event MEMC will be obligated to supply such increased
quantities; provided, however, that in no event shall the increased quantity to be supplied by MEMC in Contract Years six through eleven exceed the Yearly Target Quantities set forth on Attachment B hereto unless such excess quantities
have been requested by Gintech and agreed to by MEMC (after the required three (3) years advance notice).

 CONFIDENTIAL TREATMENT 
  

 (iii) The Yearly Minimum Quantities may also be reduced, for any Contract Year,
pursuant to and in accordance with the provisions of Section 2.2(f)(i)(A). 
 (b) Mix Between Multi Wafers and Mono
Wafers. Attachment B sets forth the aggregate yearly quantities of Multi Wafers and Mono Wafers to be supplied in each Contract Year, and does not differentiate for the purpose of aggregate yearly quantities between Multi Wafers and Mono
Wafers. In the first three Contract Years, the percentage mix between Multi Wafers and Mono Wafers supplied shall be at MEMC’s discretion; provided, however, that in such Contract Years MEMC may choose not to supply any Mono Wafers. In
Contract Years four through eleven, MEMC shall change the percentage mix between Multi Wafers and Mono Wafers based on Gintech’s request; provided that (i) Gintech has given at least three (3) years advance notice of such
requested change in percentage mix between Multi Wafers and Mono Wafers; and (ii) MEMC can reasonably accommodate such requested change in percentage mix between Multi Wafers and Mono Wafers; and provided, further, that in no event will
MEMC be obligated to supply more than [xxxxxxx] percent ([XXXX]%) of Wafers in any Contract Year as Mono Wafers, unless requested by Gintech and agreed to by MEMC. 
 (c) Prices. The prices set forth on Attachment B hereto are on a Dollar per Watt basis. Attachment B also includes,
for illustration purposes, the prices on a per Wafer basis, which price per Wafer calculations are based on an indicative average efficiency factor of [XXXX]% for Multi Wafers and an indicative average efficiency factor of [XXXX]% for
Mono Wafers. The Parties agree that the actual average efficiency factor for both Multi Wafers and Mono Wafers experienced by Gintech when using MEMC Wafers, shall be used to calculate the price per Wafer. These actual average efficiency factors
shall be subject to audit and/or verification as mutually agreed by the Parties. The Parties agree that after an average efficiency factor for both Multi Wafers and Mono Wafers is established, all prices per Multi Wafer or Mono Wafer calculated
using such average efficiency factor for the purposes of invoicing under Section 2.4 hereof shall be based on such average efficiency factor until the average efficiency factor is changed pursuant to the procedures on Attachment B. The
Parties also agree and acknowledge that as the average efficiency factor increases, based on actual measurements by the mutually agreed method of producing solar cells based on the Baseline Cell Process (as such term is defined in Attachment
B), the price per Wafer will increase (while the price per Watt remains fixed) and the quantity of Wafers supplied will decrease (while quantities of Watts remains fixed). All prices per Wafer set forth on Attachment B hereto (for the
purposes of invoicing under Section 2.4 hereof) shall be updated for efficiency changes at least as frequently as is set forth on Attachment B. 
 (d) Purchase Shortfalls. If Gintech purchases fewer Watts than the lesser of (i) the Yearly Minimum Quantity, as calculated in accordance with Section 2.2(a) or (ii) the amount of Watts
tendered for delivery by MEMC during any Contract Year, Gintech shall pay to MEMC via wire transfer of immediately available funds, within ten (10) days 

  

 6 









 CONFIDENTIAL TREATMENT 
  

 
after being invoiced therefor, the difference between (A) the amount that would have been payable by Gintech during such Contract Year if Gintech had
purchased the lesser of (i) the Yearly Minimum Quantity as calculated in accordance with Section 2.2(a) or (ii) the amount of Watts tendered for delivery by MEMC during the entire Contract Year, and (B) the amount payable
by Gintech during such Contract Year for the actual volume of Watts purchased by Gintech from MEMC based on the applicable price listed on Attachment B hereto (such calculated amount, the “Purchase Shortfall”). The Purchase
Shortfall shall accrue interest at the rate of one and one-half percent (1.5%) per month from the date of the invoice therefor, unless prohibited by Law. 
 (e) Monthly Planning; Rolling Forecast. For planning purposes only, no later
than the third (3rd) Business Day of each calendar month, Gintech shall deliver to MEMC a forecast of the
quantities of Wafers that Gintech anticipates that it will order from MEMC over the subsequent rolling twelve (12) months. Such rolling forecasts are for capacity planning purposes only, and such estimated amounts in the rolling forecasts shall
have no effect on Gintech’s obligation to purchase some or all of Gintech’s Yearly Minimum Quantity for any Contract Year or MEMC’s obligation to deliver the indicated quantities, unless such quantity is confirmed pursuant to the
procedures of Section 2.3. 
 (f) Missed Deliveries. If, in any Contract Year, MEMC fails to deliver twenty five
percent (25%) or more of the Yearly Minimum Quantities of Wafers MEMC would be required to deliver pursuant to the provisions of Section 2.2(a) (a “Missed Delivery”), and such Missed Deliveries continue uncured by the end
of such Contract Year, then the following provisions shall apply: 
 (i) MEMC shall have the right to try to “make
up” Missed Deliveries for any Contract Year through the end of the following subsequent Contract Year. The Wafer price for such Missed Deliveries, if actually made in the subsequent Contract Year, shall be the Wafer price at the time of
shipment of the Wafers. If MEMC fails to make up the Missed Deliveries prior to the end of the subsequent Contract Year, then: 
 (A) Gintech shall have the right, but not the obligation, which right must be
exercised by Gintech, in writing (and if not so exercised, shall be automatically waived for such Contract Year, and only such Contract Year), no later than the last Business Day of the following subsequent Contract Year, to reduce the Yearly
Minimum Quantity for the next following Contract Year as follows. The Yearly Minimum Quantity for such next following Contract Year shall be reduced by an amount equal to one-half ( 1/2) the amount of the Missed Deliveries for the relevant prior Contract Year (taking into account the actual deliveries made by MEMC in the subsequent Contract Year intended as
make up deliveries for the relevant prior Contract Year); and 
 (B) If Gintech chooses to reduce its Yearly Minimum
Quantity for such next following Contract Year pursuant to the provisions of Section 2.2(f)(i)(A), then a corresponding reduction in the Letter of Credit Amount shall be made pursuant to the provisions of Section 3.1(c).

 2.3 Purchase Orders and Order Acknowledgements. Gintech will issue a written purchase order to
MEMC through email, fax or internationally recognized carrier on at least a monthly basis. Such purchase orders shall contain the requested delivery dates. All such purchase orders shall be subject to the terms and conditions set forth in this
Agreement. MEMC shall, within five (5) Business Days after it receives any such purchase order, respond to such Gintech purchase orders with a written MEMC Order Acknowledgement, which MEMC Order Acknowledgement will set forth those requested
Gintech quantities for which MEMC can then confirm a quantity (which quantity may be a partial quantity of the Gintech purchase order) and an estimated shipment calendar week. MEMC Order Acknowledgements shall reference the applicable Gintech
purchase order. Until such time as MEMC has provided Gintech with an MEMC Order Acknowledgement for all Wafers requested on a Gintech purchase order, such purchase order shall not be deemed accepted by MEMC for the full amount of Wafers, but shall
only be deemed accepted by MEMC for that amount of Wafers for which a confirmed quantity and shipment week has been provided. At all times during the term of this Agreement, unless otherwise mutually agreed by the parties, Gintech shall have
provided MEMC with binding purchase orders requesting shipments of Wafers over at least the next ninety (90) days. Unless expressly agreed in writing by MEMC and Gintech, no additional or different terms or conditions contained in any
quotation, sales order, acknowledgement form, purchase order or other communication from MEMC or Gintech shall be binding upon MEMC or Gintech, and each Party hereby objects to any such additional or different terms or conditions. To the extent
there is any conflict among the terms and conditions of this Agreement, any Gintech purchase order and any MEMC Order Acknowledgement, the terms of this Agreement shall apply. 
 2.4 MEMC Invoices. MEMC invoices shall reference the applicable Gintech purchase order and shall be submitted for payment by MEMC to the Gintech
accounts payable address specified in writing from time to time by Gintech. To the extent there is any conflict between the terms and conditions of this Agreement and of any such invoice, the terms of this Agreement shall apply. All prices in the
invoices shall be based on the then-current price for each Wafer, calculated in accordance with the provisions set forth on Attachment B, on the date of confirm. 
 2.5 Terms of Sale and Shipment Terms. 
 (a) Terms of Sale. All sales of Wafers
hereunder shall be made Ex Works (Incoterms 2000: EXW) MEMC’s designated location. “Incoterms 2000” means the version of “Incoterms” adopted by the International Chamber of Commerce effective January 1, 2000,
including all amendments thereof, but excluding any amendments thereof specifically agreed to by the Parties as not being applicable to this Agreement. Notwithstanding the foregoing Ex Works terms of sale, if MEMC manufactures Wafers at a facility
located in either Europe or the United States (“Non-Asia Pacific Wafers”) and then ships such Non-Asia Pacific Wafers to Gintech, MEMC shall pay, within thirty (30) days of being invoiced by Gintech therefor, fifty percent
(50%) of all freight costs associated with such sales of Non-Asia Pacific Wafers under this Agreement, with such invoices to provide reasonable detail and supporting documentation for MEMC to confirm such freight costs.

 (b) Shipment Date. Per Section 2.3 above, the scheduled shipment date for
Wafers will be specified by MEMC in the MEMC Order Acknowledgment. 
 (c) Shipment Instructions. Gintech shall furnish
written shipping instructions to MEMC from time to time, and such shipping instructions, if different from the last shipping instructions provided by Gintech to MEMC, shall take effect no earlier than ten (10) Business Days after receipt of
such written instructions by MEMC. MEMC shall pack and ship Wafers in accordance with then-current industry standards and practice. 
 (d) Shipment Date Change Requests. Gintech may request to delay or pull in shipment of an individual delivery or any part thereof upon written notice to MEMC, subject to the following conditions: 
 (i) Unless agreed to by MEMC, the shipment date change request notice must be received by MEMC at least ninety (90) days prior to the
scheduled shipment date; and 
 (ii) If the shipment date change request notice is a delay request (a push out of requested
delivery date), Gintech must commit to nonetheless purchase the delayed Wafers no later than the end of the Contract Year in which such shipment was originally scheduled by MEMC; and 
 (iii) MEMC must agree to such request in writing; and 
 (iv) In the event of an accepted shipment date change request, Gintech shall accept delivery of and pay for Wafers already manufactured or
in the process of manufacture for such accepted purchase order at the time the shipment date change request notice is received by MEMC. 
 (e) In no event shall delay of any shipment or any part thereof as requested by Gintech pursuant to Section 2.5(d) affect, in any way, Gintech’s obligation to purchase some or all of Gintech’s Yearly
Minimum Quantity for any Contract Year, unless the provisions of Section 2.2(a) hereof would otherwise require a change to Gintech’s Yearly Minimum Quantities for that Contract Year or a subsequent Contract Year. 
 2.6 Title and Risk of Loss. Pursuant to and consistent with the Incoterms 2000 term of sale of Ex Works MEMC’s designated location, title to
and risk of loss of Wafers shall pass to Gintech at the time when the Wafers have been made available by MEMC for pickup by Gintech at MEMC’s designated location and Gintech has been notified that such Wafers have been made available by MEMC
for pickup by Gintech. 
 2.7 Payment Terms; Delivery Terms; Freight Terms. 
 (a) MEMC shall issue an invoice to Gintech for each shipment of Wafers. All invoices will be in Dollars. Payment of invoices by Gintech
shall be in Dollars, by wire

transfer, check or by other means mutually agreed on by the Parties. Payment is due thirty (30) days from the date of the invoice. MEMC reserves the
right to assess a late payment charge of one and one-half percent (1.5%) per month on the unpaid balance of any past due amount, unless prohibited by Law. If Gintech fails to pay the purchase price when due for any shipment, MEMC may, but need
not, require receipt of payment in full prior to manufacturing the balance of any outstanding or subsequent order. Payment of sums due from Gintech shall be made upon terms set forth above. MEMC may recover for each delivery hereunder as a separate
transaction, without reference to any other delivery. If Gintech has been failing to pay the purchase price when due for one or more shipments, and MEMC reasonably concludes that Gintech is in unsound financial condition and has notified Gintech of
such conclusion, and the Parties have then negotiated in good faith for at least ten (10) Business Days to remedy such conclusion, or if Gintech is in default with respect to any of the material terms and conditions of this or any other
agreement with MEMC, MEMC shall forthwith have the right to demand cash payment in advance or additional financial assurance until such time as said credit has been reestablished or default cured to MEMC’s satisfaction. If Gintech fails to pay
the purchase price when due for any shipment, MEMC may also, but need not, (i) immediately offset any late payments against the Loan/Security Deposit and/or the Letter of Credit required by Section 3.1(c) and (ii) prior to any further
shipments of Wafers, require that Gintech replenish the Loan/Security Deposit and/or the Letter of Credit required by Section 3.1(c) in accordance with the terms of this Agreement. 
 (b) All prices are based on Ex Works MEMC’s designated location. Gintech shall pay all transportation charges on a freight collect
basis. Any Taxes, levies or assessments (including related interest and penalties) imposed, levied, assessed or arising by virtue of this Agreement other than Taxes based upon the net income of MEMC shall be the liability and responsibility of
Gintech. If any charges are exempt from sales or use Tax liability, Gintech must provide MEMC with evidence of tax exemption acceptable to the relevant taxing authority. 
 2.8 Representations and Warranties. MEMC represents and warrants that the Wafers delivered to Gintech under this Agreement shall meet the specifications set forth in Attachment A hereto. EXCEPT AS SET
FORTH IN THE PRECEDING SENTENCE, MEMC MAKES NO OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, OF FITNESS OF THE WAFERS FOR PARTICULAR USE OR OTHERWISE, INCLUDING WITHOUT LIMITATION, WARRANTY OF MERCHANTABILITY AND/OR FITNESS FOR A
PARTICULAR PURPOSE. 
 2.9 Limitation of Liability. 
 (a) Limitation. MEMC’s total liability, and Gintech’s exclusive remedy, for any and all Losses and damages, arising out
of any cause whatsoever under any theory of contract, tort, strict liability, or other legal or equitable theory, including under a breach of representations and warranties made under Section 2.8 hereof, shall be limited solely to
Gintech’s actual direct damages directly caused by the failure of the Wafers to meet the specifications set forth in Attachment A hereto; provided, however, that such actual direct damages may not exceed the purchase price of the
Wafers that caused the damages, 

  

 10 









 CONFIDENTIAL TREATMENT 
  

 
or, at MEMC’s option, the repair or replacement of such Wafers; and provided further that in order to recover for the failure of the Wafers to
meet the specifications set forth in Attachment A hereto, Gintech shall be required to prove that such Wafers do not meet such specifications. In no event shall MEMC be liable for lost profits, special, incidental, consequential or punitive
damages. MEMC shall not be liable for, and Gintech assumes liability for, all personal injury and property damage connected with the handling, transportation, possession, processing, further manufacture, other use or resale of the Wafers, whether
the Wafers are used alone or in combination with any other material. 
 (b) Technical Advice. If MEMC furnishes
technical or other advice to Gintech, whether or not at Gintech’s request, with respect to processing, further manufacture, other use or resale of the Wafers, MEMC shall not be liable for, and Gintech assumes all risk of, such advice and the
results thereof, if such advice is followed by Gintech. Similarly, if MEMC offers technical or other advice to Gintech, whether or not at Gintech’s request, with respect to processing, further manufacture, other use or resale of the Wafers, and
Gintech declines to follow such advice, MEMC shall not be liable for, and Gintech assumes all risk of, such declination of advice and the results thereof. 
 2.10 Force Majeure. 
 (a) MEMC shall not be liable for any delay or failure to perform
due to any cause or condition beyond its reasonable control, whether foreseeable or not, including, without limitation, Acts of God, war, riot, fire, explosion, accident, flood or sabotage; lack of adequate fuel, power or raw materials, labor,
containers or transportation facilities; compliance with governmental requests, Laws, regulations, orders, action or national defense requirements; embargoes or acts of civil or military authorities; theft, breakage or failure of machinery or
apparatus; or in the event of labor trouble, strike, lockout or injunction (provided that MEMC shall not be required to settle a labor dispute against its own best judgment) (all of such events, a “Force Majeure Event”). MEMC shall
give prompt written notice to Gintech of any such Force Majeure Event and any associated delivery changes. 
 (b) If a Force
Majeure Event occurs, MEMC shall not be responsible for any damage, increased costs, or Losses which Gintech may sustain by reason of such failure of performance, but this Agreement shall not be regarded as terminated or frustrated as a result such
failure of performance. If a Force Majeure Event occurs, MEMC shall take appropriate means to minimize or remove the effects of the Force Majeure Event and, within the shortest practicable time, attempt to resume performance of its obligations under
this Agreement affected by the Force Majeure Event, except as may be permitted by Section 2.10(c). 
 (c) If MEMC has
suffered a Force Majeure Event and is unable to perform substantially all of its obligations under this Agreement for eighteen (18) months or more after suspension of its performance after the occurrence of a Force Majeure Event, then Gintech
and MEMC may mutually terminate this Agreement if the Parties mutually agree to terminate. Notwithstanding anything in this Agreement to the contrary, in no event shall the occurrence of a Force Majeure Event hereunder excuse either Party from its
obligations to pay to the other Party any sums accrued or due hereunder to such other Party.

[xxxxxxx] percent ([XXXX]%) interest in any Person in a Restricted Gintech Business shall be permitted. In addition, Gintech shall not, and each shall cause each of its affiliates and Subsidiaries to not, directly or indirectly, permit
investment in Gintech or its affiliates or Subsidiaries by any MEMC Competitor; provided, however, that this Section 2.11(a) shall not apply if an MEMC Competitor acquires an interest (equity or debt) in Gintech or its affiliates or
Subsidiaries through trading in the stock market without being invited by Gintech or its affiliates or Subsidiaries; and provided further that in the event that any MEMC Competitor acquires a [xxxxxxx] percent ([XXXX]%) interest
or more in Gintech or its affiliates or Subsidiaries, if requested in writing by MEMC, Gintech will use best efforts to negotiate with the MEMC Competitor in order to have such MEMC Competitor sell its position in the public markets or in a
negotiated private transaction. 
 (b) If, at the time of enforcement of the covenants contained in this Section 2.11
(the “Restrictive Gintech Covenants”), a court shall hold that the duration, scope or area restrictions stated herein are unreasonable under circumstances then existing, the Parties agree that the maximum duration, scope or area
reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court shall be allowed and directed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by
Law. Upon advice of legal counsel, Gintech has determined and hereby acknowledges that the Restrictive Gintech Covenants are reasonable in terms of duration, scope and area restrictions. Gintech acknowledges that both MEMC and Gintech have been
doing business throughout the world. 
 (c) If Gintech or any of its affiliates or Subsidiaries breaches, or threatens to
commit a breach of, any of the Restrictive Gintech Covenants, MEMC shall have the following rights and remedies, each of which rights and remedies shall be independent of the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to MEMC at law or in equity: 
 (i) the right and remedy to have the
Restrictive Gintech Covenants specifically enforced by any court of competent jurisdiction, it being agreed that any breach or threatened breach of the Restrictive Gintech Covenants would cause irreparable injury to MEMC and that money damages would
not provide an adequate remedy to MEMC; and 
  

 12 









 CONFIDENTIAL TREATMENT 
  

 (ii) the right and remedy to require such Person to account for and pay over to MEMC
any profits, monies, accruals, increments or other benefits derived or received by such Person as the result of any transactions constituting a breach of the Restrictive Gintech Covenants; and 
 (iii) the right and remedy to cease deliveries of Wafers hereunder until the breach of any of the Restrictive Gintech Covenants is cured.

 2.12 Noncompete in Favor of Gintech. 
 (a) MEMC understands that Gintech shall be entitled to protect and preserve the going concern value of its business to the extent permitted by Law and that Gintech would not have entered into this Agreement absent the
provisions of this Section 2.12. Therefore, during the Initial Term (and any extensions of the Initial Term pursuant to Section 4.1 hereof), except as may be agreed to in writing by Gintech in advance of engaging in any activities, MEMC
shall not, and each shall cause each of its affiliates and Subsidiaries to not, directly or indirectly, engage in any Restricted MEMC Business anywhere in the world including (A) owning any interest in, managing, operating, controlling or
participating in any Person which owns or operates a Restricted MEMC Business, (B) soliciting any customer or prospective customer of Gintech anywhere in the world to purchase any products or services which compete with those provided by
Gintech and (C) assisting any Person in any way to do, or attempt to do, anything prohibited above; provided, however, that the ownership by MEMC of up to a [xxxxxxx] percent ([XXXX]%) interest in any Person in a Restricted
MEMC Business shall be permitted. 
 (b) If, at the time of enforcement of the covenants contained in this Section 2.12
(the “Restrictive MEMC Covenants”), a court shall hold that the duration, scope or area restrictions stated herein are unreasonable under circumstances then existing, the Parties agree that the maximum duration, scope or area
reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court shall be allowed and directed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by
Law. Upon advice of legal counsel, MEMC has determined and hereby acknowledges that the Restrictive MEMC Covenants are reasonable in terms of duration, scope and area restrictions. MEMC acknowledges that both Gintech and MEMC have been doing
business throughout the world. 
 (c) If MEMC or any of its affiliates or Subsidiaries breaches, or threatens to commit a
breach of, any of the Restrictive MEMC Covenants, Gintech shall have the following rights and remedies, each of which rights and remedies shall be independent of the others and severally enforceable, and each of which is in addition to, and not in
lieu of, any other rights and remedies available to Gintech at law or in equity: 
 (i) the right and remedy to have the
Restrictive MEMC Covenants specifically enforced by any court of competent jurisdiction, it being agreed that any breach or threatened breach of the Restrictive MEMC Covenants would cause irreparable injury to Gintech and that money damages would
not provide an adequate remedy to Gintech and 
  

 13 









 CONFIDENTIAL TREATMENT 
  

 (ii) the right and remedy to require such Person to account for and pay over to
Gintech any profits, monies, accruals, increments or other benefits derived or received by such Person as the result of any transactions constituting a breach of the Restrictive MEMC Covenants. 
 2.13 Preferred Vendor. The quantities of Wafers to be supplied by MEMC hereunder assume that in any Contract Year such amount of Wafers will be
approximately [XXXX]% of Gintech’s then current solar wafer demand, and the Yearly Minimum Quantities and Yearly Target Quantities of Wafers set forth in Attachment B, as modified by Section 2.2(a), reflect this mutual
intention of the parties. In addition, MEMC shall be considered as a preferred vendor and shall have an annual right of first refusal (but not an obligation, unless MEMC would be so obligated pursuant to Section 2.2(a) hereof) to negotiate with
Gintech to supply Gintech with additional Wafers, in excess of [xxxxxxx] percent ([XXXX]%) of Gintech’s then current demand for Wafers (such potential amount, the “Additional Wafer Supply”). The price per watt for
such Additional Wafer Supply shall be negotiated by the parties. If the parties are unable to reach agreement on price and quantity for such Additional Wafer Supply by November 1 for the ensuing Contract Year commencing on January 1,
Gintech may buy such Additional Wafer Supply from other suppliers. Such Additional Wafer Supply, if supplied by MEMC, shall not be added to the Yearly Minimum Quantity for the then current Contract Year or any Contract Year thereafter unless the
parties expressly agree. 
 ARTICLE III 
 LOAN/SECURITY DEPOSIT AND LETTER OF CREDIT; EXECUTION OF ADDITIONAL 
 AGREEMENTS 
 3.1 Loan/Security Deposit. To induce MEMC to invest in additional polysilicon production and wafer manufacturing capacity, Gintech agrees to loan
MEMC, per the schedule set forth on Attachment C hereto, the amount of $341.3 million (the “Loan/Security Deposit”), as a means of securing Gintech’s obligations to MEMC, which Loan/Security Deposit shall be repaid by
MEMC, without interest, up to the amount of $324.2 million (95% of the aggregate Loan/Security Deposit amount, such retained amount of $17.1 million, the “Retained Loan/Security Deposit Amount”), according to the repayment schedule
set forth on Attachment C hereto, unless Gintech has not purchased the Yearly Minimum Quantities in any Contract Year under the “take or pay” provisions of Section 2.2(a) hereof, in which case MEMC may choose to offset pursuant
to this Article III any payments required from Gintech under Section 2.2(a) hereof against MEMC’s obligation to repay the Loan/Security Deposit. 
  

 14 









 CONFIDENTIAL TREATMENT 
  

 (a) In any Contract Year when Gintech is required to pay MEMC a portion of the
Loan/Security Deposit per the schedule set forth on Attachment C, payment by Gintech to MEMC shall be made, in full, no later than the fifth Business Day of the applicable Contract Year; provided, however, that Gintech shall be
entitled to request MEMC to calculate the difference between the amount of the Loan/Security Deposit repayable by MEMC pursuant to Section 3.1(b) and the amount of the Loan/Security Deposit payable by Gintech in any Contract Year, and Gintech
shall pay such difference to MEMC no later than the fifth Business Day of the applicable Contract Year. In connection with the Loan/Security Deposit amount to be paid by Gintech to MEMC for the first Contract Year, twenty five percent (25%) of
the Loan/Security Deposit amount to be paid by Gintech to MEMC for that first Contract Year shall be paid to MEMC three (3) Business Days after the date of this Agreement, and seventy five percent (75%) of the Loan/Security Deposit amount
to be paid by Gintech to MEMC for that first Contract Year shall be paid to MEMC on or before the first shipment date for Wafers. 
 (b) In any Contract Year when MEMC is required to repay a portion of the Loan/Security Deposit to Gintech per the schedule set forth on Attachment C, payment by MEMC to Gintech shall be made, in full, no later than the fifth Business
Day of the applicable Contract Year; provided, however, that if in any Contract Year there is a Purchase Shortfall that has not been paid by Gintech via wire transfer to MEMC in accordance with the provisions of Section 2.2(d) hereof,
MEMC shall not be required to repay that portion of the Loan/Security Deposit up to the Purchase Shortfall in the next Contract Year, but instead MEMC may retain the amount of the Loan/Security Deposit up to the Purchase Shortfall (including the
amount of any interest accrued on the Purchase Shortfall in accordance with Section 2.2(d) hereof, until the date that MEMC actually transfers or retains such amount); and provided further, that if in any Contract Year there is a
Purchase Shortfall (or an aggregate Purchase Shortfall from more than one Contract Year) that has not been paid by Gintech to MEMC in excess of the amount of any Loan/Security Deposit not yet repaid by MEMC, MEMC may withhold repayment in any future
Contract Years of the Loan/Security Deposit up to the amount of the aggregate unpaid Purchase Shortfall. If the aggregate unpaid Purchase Shortfall(s) exceed the remaining Loan/Security Deposit not yet repaid by MEMC, MEMC shall have any and all
remedies available to it to recover from Gintech immediately the amount of any aggregate unpaid Purchase Shortfall, including drawing on the Letter of Credit pursuant to the provisions of Section 3.1(c). 
 (c) The Parties have also agreed that the amount of the Loan/Security Deposit outstanding in any Contract Year is less than the
appropriate amount of security to be held by MEMC in order to ensure payment for Gintech’s “take or pay” obligations under Section 2.2(a) hereof. Accordingly, the Parties have agreed that Gintech will be required to deliver to
MEMC, no later than the seventh Business Day of each Contract Year, an irrevocable Letter of Credit drawn on a bank that is requested by Gintech and approved by MEMC (the “LC Bank”), in an amount equal to the Required Letter of
Credit Amount for such Contract Year as is set forth on Attachment C (the “Letter of Credit Amount”), and that expires on the eighth Business Day of the subsequent Contract Year. Gintech may, in its discretion, use quarterly
or half-year revolving Letters of Credit to cover the full Letter of Credit Amount during any respective Contract Year; provided, however,  

  

 15 









 CONFIDENTIAL TREATMENT 
  

 
that in no event shall there ever be a gap in coverage (i.e., a Letter of Credit will not be permitted to expire before a replacement Letter of Credit is put
in place). MEMC’s right to unilaterally draw on the Letter of Credit (after exhaustion of the Loan/Security Deposit amount then held by MEMC) shall be substantially similar to those rights set forth in Section 3.1(b) above. The Letter of
Credit Amount set forth on Attachment C for each Contract Year was calculated as follows: 
 (i) In Contract Year one,
the Letter of Credit Amount shall be equal to twelve (12) months of MEMC’s revenue under this Agreement, based on the minimum quantity of Wafers for that Contract Year at the pricing for that Contract Year (assuming all Multi Wafers),
less the cumulative net amount of the Loan/Security Deposit then held by MEMC; 
 (ii) In Contract Year two, the Letter
of Credit Amount shall be equal to nine (9) months of MEMC’s revenue under this Agreement, based on the minimum quantity of Wafers for that Contract Year at the pricing for that Contract Year (assuming all Multi Wafers), less the
cumulative net amount of the Loan/Security Deposit then held by MEMC; and 
 (iii) In Contract Year three through Contract
Year eleven, the Letter of Credit Amount shall be equal to six (6) months of MEMC’s revenue under this Agreement, based on the minimum quantity of Wafers for that Contract Year at the pricing for that Contract Year (assuming an split
between Multi Wafers and Mono Wafers of 75%/25%, respectively), less the cumulative net amount of the Loan/Security Deposit then held by MEMC. 
 (iv) In any Contract Year for which the Yearly Minimum Quantity is adjusted upward or downward pursuant to the provisions of Section 2.2(a) or Section 2.2(f)(i)(A), the Letter of Credit Amount will also be
adjusted upward or downward consistent with the provisions of this Section 3.1(c). 
 (d) The Parties have also agreed
that the amount of the Loan/Security Deposit outstanding in any Contract Year to be held by MEMC in order to ensure payment for Gintech’s “take or pay” obligations under Section 2.2(a) hereof may be adjusted pursuant to the
provisions of this Section 3.1(d) as follows: 
 (i) Beginning in Contract Year two, every October 1 and
April 1 Gintech will provide MEMC with complete financial statements for the six months and twelve months ended June 30 and December 31, respectively (such financial statements, the “Financial Statements”). From the
Financial Statements, MEMC will verify whether Gintech meets the Guaranteed Financial Performance Criteria. 
 (ii) If the
Guaranteed Financial Performance Criteria for the prior twelve (12) month period are met, then the Letter of Credit Amount shall not be adjusted pursuant to this Section 3.1(d). 
  

 16 









 CONFIDENTIAL TREATMENT 
  

 (iii) If, however, the Guaranteed Financial Performance Criteria for the prior twelve
(12) month period are not met, then the Letter of Credit Amount shall be adjusted pursuant to this Section 3.1(d), by Gintech being required to increase the amount of security for MEMC by increasing the Letter of Credit Amount by an
additional six (6) months of months of MEMC’s revenue under this Agreement, based on the minimum quantity of Wafers for that Contract Year at the pricing for that Contract Year (assuming a split between Multi Wafers and Mono Wafers of
[XXXX]%/[XXXX]%, respectively), less the cumulative net amount of the Loan/Security Deposit then held by MEMC (e.g., in Contract Year two the total amount of required revenue months to be held as security would be fifteen
(15) and in Contract Years three through eleven, the total amount of required revenue months would be twelve (12)). 
 (iv) In the event that Gintech will be required to increase the Letter of Credit Amount pursuant to Section 3.1(d)(iii), then Gintech shall deliver to MEMC a Letter of Credit for the increased amount no later than ten
(10) Business Days after MEMC has performed the calculation required by Section 3.1(d)(i) above and has requested an increase in the Letter of Credit Amount from Gintech in writing. All other terms and provisions of this Agreement shall
apply to any Letter of Credit required by this Section 3.1(d). 
 (v) Notwithstanding the foregoing provisions of this
Section 3.1(d), if the quantity of Wafers tendered for delivery by MEMC during the just-ended Contract Year is less than the Yearly Minimum Quantities for such just-ended Contract Year, then each of the financial performance measures that make
up the Guaranteed Financial Performance Criteria shall be reduced by the same percentage as the amount that the quantity of Wafers tendered for delivery by MEMC during the just-ended Contract Year is less than the Yearly Minimum Quantities for such
just-ended Contract Year (e.g., if MEMC has tendered for delivery only 95% of the Yearly Minimum Quantity for a Contract Year, then the threshold amount of each of the financial performance measures that make up the Guaranteed Financial Performance
Criteria shall be reduced to only 95% of such amounts). 
 3.2 Execution of Gintech Silicon Material Corporation Stock Purchase
Agreement. 
 (a) Concurrently with the execution of this Agreement, Gintech and MEMC shall execute the Gintech Silicon
Material Corporation Stock Purchase Agreement, pursuant to which Gintech shall transfer to MEMC one hundred percent (100%) of the ownership interests in Gintech Silicon Material Corporation (“Gintech Material”) as soon as
practicable after December 16, 2006, but in no event later than December 31, 2006, which ownership interests shall then include all associated Tax holidays and benefits and incentives from Governmental Authorities, for lease of that
certain 1.7 hectare parcel or that certain 1.8 hectare parcel of land and/or real property located in Hsin Chu Science Park (the “Real Property Interest”) suitable for MEMC to build a factory thereon to manufacture some of the Wafers
should MEMC so choose. 
  

 17 









 CONFIDENTIAL TREATMENT 
  

 (b) Gintech warrants and represents that Gintech Material is qualified to enjoy the
tax incentives (five years tax holidays) as provided for under Article 9 of the Statute for Upgrading Industries, pursuant to the approval letter (Ref. No. Kong Hua Zi 09400716260) issued by the Industrial Development Bureau (“IDB”) dated
December 31, 2005. 
 (c) The Parties acknowledge and agree that such five years tax holidays status was granted based upon
the original investment proposal submitted by Gintech Material to IDB. The Parties agree to cooperate with each other to amend the original investment proposal of Gintech Material to ensure that after being acquired by MEMC, Gintech Material will
still be able to enjoy such five years tax holidays status based upon such amended investment proposal and seek the required regulatory approval for such amended investment proposal. 
 (d) If such five years tax holidays status granted to Gintech Material is cancelled or revoked, MEMC shall be entitled to hold back from
the Loan/Security Deposit the amount of [xxxxxxx] Dollars ($[XXXX]) per year for each of the five years of such cancelled or revoked tax holidays status; provided, however, that in no event shall Gintech be subject to any such
hold back in the case where such five years tax holidays status is cancelled or revoked for any of the following reasons: (i) Gintech Material fails to submit the amended investment proposal for IDB’s approval on or before December 31, 2006;
(ii) Gintech Material fails to complete the construction of a new manufacturing facility with the minimum capacity of 100 Megawatts in Taiwan for manufacture of solar wafers on or before December 31, 2009 (after the granting of a one year extension
by the IDB, if so requested by MEMC and/or Gintech Material); or (iii) the total amount of investment made by MEMC in Gintech Material is less than US$[XXXX] on or before December 31, 2009 (after the granting of a one year extension by the
IDB, if so requested by MEMC and/or Gintech Material). 
 3.3 Execution of Share Subscription Agreement. Concurrently with the
execution of this Agreement, Gintech and MEMC shall execute the Share Subscription Agreement, pursuant to which MEMC shall purchase 7.8 million shares of Gintech stock at NT$10 per share. 
 ARTICLE II 
 TERM AND TERMINATION 
 4.1 Term. The Term of this Agreement shall commence on the Effective Date and shall expire ten (10) years following the Effective Date (the
“Initial Term”). No less than twelve (12) months prior to the expiration of the Initial Term, the Parties agree to negotiate in good faith to extend the Initial Term of the Agreement, with such negotiations intended to address
price, quantity (including minimum quantities) and length of any extension term. In no event shall this Agreement be extended beyond the Initial Term unless the Parties expressly agree on all material terms of such extension. 
 4.2 Termination by Either Party. Either Party to this Agreement may terminate this Agreement by written notice to the other Party
if, and only if, such other Party (a) becomes 
  

 18 









 CONFIDENTIAL TREATMENT 
  

 
insolvent, (b) makes a general assignment for the benefit of creditors, (c) suffers or permits the appointment of a receiver for its business or
assets, (d) becomes subject as the debtor to any proceeding under any bankruptcy or insolvency Law, whether domestic or foreign, and such proceeding is not dismissed with prejudice within sixty (60) days after filing, or (e) commences
liquidation or dissolution proceedings, voluntarily or otherwise. In addition, if a Force Majeure Event has occurred, and the Parties have mutually agreed to terminate this Agreement pursuant to the provisions of Section 2.10(c), this Agreement
shall be so terminated on the date the Parties have agreed shall be the termination date. 
 4.3 Termination by MEMC. 
 (a) In the event that Gintech has failed to pay a Purchase Shortfall to MEMC within five (5) Business Days of being notified thereof,
and the amount of the unpaid Purchase Shortfall is greater than the amount of the Loan/Security Deposit and Letter of Credit then held by MEMC, then MEMC shall have the right, upon at least ten (10) Business Days prior written notice to Gintech
in accordance with the notice provisions of Section 7.4, to immediately terminate this Agreement if: 
 (i) Gintech has not paid to MEMC, in immediately available funds, the amount of the
unpaid Purchase Shortfall (after MEMC shall have retained the Loan/Security Deposit and drawn on the Letter of Credit) no later than the ninth (9th) Business Day after receiving such written notice; and 
 (ii) Gintech has not replenished the Loan/Security Deposit to be held by MEMC
(after MEMC has retained the Loan/Security Deposit) by wiring MEMC, in immediately available funds, the amount of the Loan/Security Deposit as would be required for such Contract Year by Attachment B (taking into account the provisions of
Section 2.2(a), Section 2.2(f), Section 3.1(c) and Section 3.1(d) hereof) and replaced the Letter of Credit with a new Letter of Credit in the amount of the Letter of Credit Amount required for such Contract Year by Attachment
B (taking into account the provisions of Section 2.2(a), Section 2.2(f), Section 3.1(c) and Section 3.1(d) hereof) no later than the ninth (9th) Business Day after receiving such written notice. 
 4.4 Termination by Gintech. 
 (a) In the event that MEMC has failed to deliver the Yearly Minimum Quantities
as would be required to be delivered pursuant to the provisions of Section 2.2(a) hereof (taking into account the provisions, including the recovery provisions, of Section 2.2(f)(i) hereof) for three (3) consecutive Contract Years,
then, no later than thirty (30) days after the end of such third consecutive Contract Year, Gintech may provide written notice to MEMC that Gintech intends to immediately terminate this Agreement. Such termination will take effect five
(5) Business Days thereafter if the breach is not cured by MEMC within such five (5) Business Day period; provided, however, that Gintech shall be required to accept delivery of and pay for Wafers already manufactured or in the
process of manufacture for any accepted purchase orders at the time the termination notice pursuant to this Section 4.4(a) is received by MEMC in accordance with the notice provisions of Section 7.4. 
  

 19 









 CONFIDENTIAL TREATMENT 
  

 (b) If Gintech would have the right to terminate this Agreement pursuant to
Section 4.4(a), but Gintech does not provide written notice of such intent to terminate to MEMC within the prescribed time frames of Section 4.4(a), then Gintech may not terminate this Agreement pursuant to Section 4.4(a) for that
entire Contract Year, and will be deemed to have waived such right to terminate this Agreement pursuant to Section 4.4(a) for that three (3) Contract Year period of missed deliveries. In such event, Gintech can still “count” the
two most recent Contract Years of missed deliveries of Wafers (as would be required to be delivered by MEMC pursuant to the provisions of Section 2.2(a) hereof (taking into account the recovery provisions of Section 2.2(f)(i) hereof)) for
the purposes of determining whether, at the end of the subsequent Contract Year, a new right to terminate this Agreement pursuant to Section 4.4(a) has been triggered. In such case, the provisions of both Section 4.4(a) and this
Section 4.4(b) shall again apply. 
 4.5 Effect of Termination. Upon termination or expiration of this Agreement, the
Parties’ obligations hereunder shall terminate. Notwithstanding the foregoing, the provisions of Section 2.2, Section 2.9, Article V and Article VI are of a continuing nature and shall survive termination of this Agreement
for any reason. No such termination shall relieve any Party from liability for any prior or subsequent breach of this Agreement. If the termination was validly made by Gintech pursuant to Section 4.2 or Section 4.4(a), MEMC shall return
the balance of Loan/Security Deposit to Gintech within sixty (60) days of the termination. 
 ARTICLE V 
 INDEMNIFICATION 
 5.1 Indemnification
Generally. Gintech shall indemnify and defend MEMC and its directors, officers, employees, contractors and agents, from any liability (including reasonable attorneys’ fees) for any Loss or injury to persons or property which may result from
Gintech’s breach of its representations, warranties or covenants in this Agreement. 
 5.2 Resolution of Disputes; Litigation.

 (a) Prior to initiating any legal or other action or proceeding against the other, the Parties shall attempt in good faith
to resolve any controversy or claim arising from or relating to this Agreement promptly by negotiations between the respective representatives of the Parties. The disputing Party shall give the other Party written notice of the dispute. Within
twenty (20) days after receipt of such notice, the receiving Party shall submit a written response to the other Party. The notice and response shall include a statement of the respective Party’s position and arguments supporting its
position. The representatives shall meet at a mutually acceptable time and place within thirty (30) days after the date of the disputing Party’s notice and thereafter as often as they reasonably deem necessary to exchange relevant
information and to attempt to resolve the dispute. If the matter has not been resolved through negotiation within sixty 

  

 20 









 CONFIDENTIAL TREATMENT 
  

 
(60) days after the date of the disputing Party’s notice, or if either Party will not meet with the other Party within thirty (30) days after the
date of the disputing Party’s notice, then either Party is free to bring any legal action or proceeding, so long as such legal action or proceeding complies with the provisions of Section 7.12 hereof. All deadlines specified herein may be
extended by mutual written agreement of the Parties. 
 (b) If no agreement can be reached between the Parties after good
faith negotiation above, either Gintech or MEMC may bring any legal action or proceeding, so long as such legal action or proceeding complies with the provisions of Section 7.12 hereof, unless the amount of the damage or loss is at issue in a
pending action or proceeding involving a third party claim, in which event such action or proceeding shall not be commenced until such amount is ascertained or both Parties agree to the action or proceeding. 
 (c) In the event that any suit or action is instituted to enforce any provision in this Agreement, the prevailing Party in such dispute
shall be entitled to recover from the losing Party all fees, costs and expenses of enforcing any right of such prevailing Party under or with respect to this Agreement, including without limitation, such reasonable fees and expenses of attorneys and
accountants, which shall include, without limitation, all fees, costs and expenses of appeals. 
 5.3 Time Limits. Any right to
indemnification or other recovery under this Article V shall only apply to Losses arising from claims with respect to which the Indemnified Person shall have notified the Indemnifying Person in writing within one (1) year of the occurrence
of the facts giving rise to the underlying claim; provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any Losses arising from claims as to which the Indemnified Person shall have, before
the expiration of the one (1) year period, previously delivered a notice pursuant to Section 5.2 to the Indemnifying Person. 
 5.4
General Indemnification Provisions. 
 (a) The Indemnifying Party shall pay the Indemnified Party immediately available
funds on an as-incurred basis for any Losses for which the Indemnified Party is entitled to indemnification hereunder. Any such indemnification payments shall include interest at the rate of 5% per annum (computed on the basis of a 360-day
year) from the date any such Losses are suffered or sustained by the Indemnified Party. 
 (b) If and to the extent that any
provision of Section 5.1 is unenforceable for any reason, each Party hereto agrees to make the maximum contribution to the payment and satisfaction of any Losses as to which such Party would otherwise have been responsible for indemnification
which is permissible under applicable Law. 
 (c) Each Indemnifying Party hereby waives (i) presentment, demand, protest,
notice of protest, notice of dishonor and notice of nonpayment; (ii) the right, if any, to the benefit of, or to direct the application of, any security hypothecated to Indemnified Party (if any), until all indemnification liability of another
Indemnifying Party to Indemnified Party, howsoever arising, shall have been satisfied; (iii) the right to require the 

  

 21 









 CONFIDENTIAL TREATMENT 
  

 
Indemnified Party to proceed against another Indemnifying Party, or to pursue any other remedy in Indemnified Party’s power (if any); and agrees that
Indemnified Party may proceed against Indemnifying Party directly and independently of any other Indemnifying Party, and that any extension, forbearance, amendment, or acceptance, release or substitution of security, or any impairment or suspension
of Indemnified Party’s remedies or rights against another Indemnifying Party or the cessation of the liability for indemnification hereunder of another Indemnifying Party for any reason other than full satisfaction of the indemnification
obligation at issue, shall not in anywise affect the liability of Indemnifying Party hereunder. 
 ARTICLE VI

developed by Gintech. The confidentiality obligations of Gintech hereunder shall continue during the term of this Agreement and for a period of ten (10) years after termination. 
 (c) The Parties to this Agreement shall consult with each other as to the form, substance and timing of any press release or other public
disclosure related to this Agreement or the transactions contemplated hereby and no such press release or other public disclosure shall be made without the consent of the other Party hereto, which consent shall not be unreasonably withheld or

 6.2 Equitable Relief. Notwithstanding any other provision of this Agreement, it is understood
and agreed that the remedy of indemnity payments pursuant to Article V and other remedies at law may be inadequate in the case of any breach of the covenants contained in this Article VI. Accordingly, either Party shall be entitled to seek
equitable relief, including the remedy of specific performance, with respect to any breach or attempted breach of such covenants. 
 ARTICLE VII 
 GENERAL PROVISIONS 
 7.1 No Partnership. Nothing contained in this Agreement shall create or shall be construed as creating a partnership, a joint venture or an agency relationship between the Parties to this Agreement. The Parties
