 Exhibit 10.3 
 AGREEMENT REGARDING 
 CHANGE OF CONTROL OR SEPARATION OF SERVICE 
 This agreement (“Agreement”) is made and entered into effective as of
                     (“Effective Date”), by and between Tanox, Inc. (“Tanox” or the “Company”), whose address is
10301 Stella Link, Houston, Texas, 77025, and                      (“Executive”), whose address is
                    . This Agreement may sometimes refer to Tanox and Executive singularly as a “Party” or collectively as the
“Parties.” 
 1. Confirmation of Employment At-Will 
 Executive’s employment with Tanox has been, is, and shall continue to be on an at-will basis. This means that either Executive or Tanox may
terminate Executive’s employment with the Company at any time and for any reason or no reason at all, except that if (a) a Change in Control of the Company shall have occurred and the Executive’s employment by the Company is
thereafter terminated (whether by the Executive with Good Reason or the Company without Cause as provided in Paragraph 3), or (b) Executive’s employment is terminated in certain other circumstances delineated in this Agreement, then the
Executive shall be entitled to receive certain benefits as provided in this Agreement. 
 2. Change of Control 
 A “Change of Control” shall be deemed to have occurred on the date that one or more of the following occurs: 
 A. Individuals who, on the date hereof, constitute the entire Board of Directors of the Company (“Incumbent Directors”) cease for any reason to
constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a
majority of the then Incumbent Directors shall be considered as though such individual was an Incumbent Director, but excluding, for this purpose any such individual whose initial assumption of office occurs as a result of either an actual or
threatened election contest, as such terms are used in Rule 14a-11 under the Securities Exchange Act of 1934, as amended (“Exchange Act”) or other actual or threatened solicitation of proxies or consents by or on behalf of any Person (as
defined below) other than the Board; 
 B. The stockholders of the Company shall approve (i) any merger, consolidation or
recapitalization of the Company (or, if the capital stock of the Company is affected, any subsidiary of the Company), or any sale, lease, or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a
single plan) of all or substantially all of the assets of the Company (each of the foregoing being an “Acquisition Transaction”) where (1) the stockholders of the Company immediately prior to such Acquisition Transaction would not
immediately after such Acquisition Transaction beneficially own, directly or indirectly, shares or 
  

 Page 1 

 other ownership interests representing in the aggregate fifty one percent (51%) or more of (a) the then
outstanding common stock or other equity interests of the corporation or other entity surviving or resulting from such merger, consolidation or recapitalization or acquiring such assets of the Company, as the case may be (the “Surviving
Entity”) (or of its ultimate parent corporation or other entity, if any), and (b) the Combined Voting Power of the then outstanding Voting Securities of the Surviving Entity (or of its ultimate parent corporation or other entity, if any)
or (2) the Incumbent Directors at the time of the initial approval of such Acquisition Transaction would not immediately after such Acquisition Transaction constitute a majority of the Board of Directors, or similar managing group, of the
Surviving Entity (or of its ultimate parent corporation or other entity, if any), or (ii) any plan or proposal for the liquidation or dissolution of the Company; or 
 C. Any Person other than Nancy T. Chang or Tse Wen Chang shall be or become the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of securities of the Company
representing in the aggregate more than forty percent (40%) of either (i) the then outstanding shares of common stock of the Company (“Common Stock”) or (ii) the Combined Voting Power of all then outstanding Voting
Securities of the Company; provided, however, that notwithstanding the foregoing, a Change in Control shall not be deemed to have occurred for purposes of this Subsection (C): 
 (1) Solely as a result of an acquisition of securities by the Company which, by reducing the number of shares of Common Stock or other Voting Securities
outstanding, increases (a) the proportionate number of Common Stock beneficially owned by any Person to more than forty percent (40%) of the Common Stock then outstanding, or (b) the proportionate voting power represented by the
Voting Securities beneficially owned by any Person to more than forty percent (40%) of the Combined Voting Power of all then outstanding Voting Securities; or 
 (2) Solely as a result of an acquisition of securities directly from the Company except for any conversion of a security that was not acquired directly from the Company, 
 (3) provided, further, that if any Person referred to in paragraph (1) or (2) of this Subsection (C) shall thereafter become the
beneficial owner of any additional Common Stock or other Voting Securities of the Company (other than pursuant to a stock split, stock dividend or similar transaction), then a Change in Control shall be deemed to have occurred for purposes of this
Subsection (C). 
 D. For purposes of the definition of “Change in Control”: 
 (i) “Affiliate” shall mean, as to a specified Person, another Person that directly, or indirectly through one or more intermediaries, controls
or is controlled by, or is under common control with, the specified Person, within the meaning of such terms as used in Rule 405 under the Securities Act of 1933, as amended (“Securities Act”), or any successor rule. 
 (ii) “Combined Voting Power” shall mean the aggregate votes entitled to be cast generally in the election of the Board of Directors, or similar
managing group, of a corporation or other entity by holders of then outstanding Voting Securities of such corporation or other entity. 
  

 Page 2 

 (iii) “Person” shall mean any individual, entity (including, without limitation, any
corporation, partnership, trust, joint venture, association or governmental body) or group (as defined in Sections 14(d)(3) or 15(d)(2) of the Exchange Act and the rules and regulations thereunder); provided, however, that Person shall not include
the Company, any of its subsidiaries, any employee benefit plan of the Company or any of its majority-owned subsidiaries or any entity organized, appointed or established by the Company or such subsidiaries for or pursuant to the terms of any such
plan. 
 (iv) “Voting Securities” shall mean all securities of a corporation or other entity having the right under ordinary
circumstances to vote in an election of the Board of Directors, or similar managing group, of such corporation or other entity. 
 3.
Termination Following a Change in Control 
 A. If a Change in Control of the Company shall have occurred, any subsequent termination
of Executive’s employment (i) by the Executive upon an Event of Termination for Good Reason (hereafter defined) or (ii) by the Company upon an Event of Termination for Cause (hereafter defined), shall be communicated by written notice
to the other party. If the notice is from the Company and states that the Executive’s employment by the Company is terminated by the Company as a result of the occurrence of an Event of Termination for Cause, the notice shall specifically
describe the action or inaction of the Executive that the Company believes constitutes an Event of Termination for Cause. If the notice is from the Executive and states that the Executive’s employment by the Company is terminated by the
Executive as a result of the occurrence of an Event of Termination for Good Reason, the notice shall specifically describe the action or inaction of the Company that the Executive believes constitutes an Event of Termination for Good Reason.

 B. An “Event of Termination for Cause” shall have occurred: (i) if Executive should be convicted of or pleads nolo
contendre to any felony offense or to a crime that the Board determines, in its sole discretion, is a crime of moral turpitude (whether or not a felony); (ii) if Executive should commit willful misconduct (that is, done in bad faith or
without reasonable belief that such action is in the best interest of the Company) or violate any law in connection with the performance of any of Executive’s duties, including, without limitation, (a) misappropriation of funds or property
of the Company or any of its affiliates or customers, (b) securing or attempting to secure personally any profit in connection with any transaction entered into on behalf of the Company or any of its affiliates, or (c) making any material
misrepresentation to the Board, the Company, or any of the Company’s affiliates; (iii) if Executive materially violates or fails to comply with any written Company policy; (iv) if Executive materially breaches any term of this
Agreement; or (v) the willful and continued failure or neglect of the Executive to substantially perform his/her duties with the Company (other than any such failure resulting from incapacity due to physical or mental illness). The Board shall
not have Cause to terminate Executive’s employment under Paragraph 3.B. (iii), (iv), or (v) of this Agreement unless and until the Board provides written notice to Executive identifying Executive’s alleged violation of policy, breach
of this Agreement, or failure to perform (or neglect of) any duty and Executive fails to cure such violation of policy, breach of this Agreement or failure to perform (or neglect of) any duty within 60 days. 
  

 Page 3 

 C. An “Event of Termination for Good Reason” shall have occurred in the event of any of the
following: 
 (i) Executive’s assignment to any duties or the significant reduction of Executive’s duties or a significant
change of Executive’s title, any of which is inconsistent with his or her position or title with the Company and responsibilities in effect immediately prior to such assignment, except in each case in connection with a promotion. For purposes
of clarification, if Executive is not the Vice President of Human Resources of the successor entity or its ultimate parent, if any, then Executive will have suffered a significant reduction of his/her duties which qualifies as an Event of
Termination for Good Reason pursuant to this paragraph; 
 (ii) reduction by the Company in Executive’s base compensation as in
effect immediately prior to such reduction, provided that an Event of Termination for Good Reason shall not be deemed to have occurred where Executive’s base compensation is reduced as part of an overall cost reduction program that affects all
senior executives of the Company and does not disproportionately affect Executive; 
 (iii) any purported termination of Executive by
the Company (other than a voluntary resignation initiated by Executive, except for a voluntary termination initiated by Executive for the reasons described in this paragraph) which is not effected for disability or for Cause; 
 (iv) relocation of Executive’s principal place of employment by more than 50 miles; 
 (v) the failure of any successor entity to the Company to expressly assume in writing the terms of this agreement; and 
 (vi) any material breach by the Company of any material provision of this agreement which has not been cured within 30 days of written notice to the
Company by Executive of such breach. 
 4. Severance Benefits 
 A. If a Change of Control occurs and, within one year thereafter, the Executive’s employment by the Company is terminated by the Executive following
an Event of Termination for Good Reason or by the Company otherwise than as a result of an Event of Termination for Cause, Executive will be entitled to receive Change of Control Severance Benefits consisting of: (a) a lump sum payment equal to
one year of Executive’s base salary as in effect immediately prior to the Change of Control (minus lawful withholdings); (b) a lump sum payment equal to the dollar amount of Executive’s full target bonus percentage as in effect
immediately prior to the Change of Control (minus lawful withholdings); (c) a lump sum payment of $15,000 (minus lawful withholdings) that Executive may use for benefit continuation under COBRA or for any other purpose; and (d) accelerated
vesting of Executive’s stock options under any stock option agreement(s) between Executive and Tanox, meaning that all outstanding but unvested stock 
  

 Page 4 

 options shall be accelerated and fully vested, and all vested options shall be exercisable until the later of
(i) the 15th day of the third month following the date at which the stock options would otherwise have expired
in accordance with their original terms, (ii) December 31 of the calendar year in which the stock options would otherwise have expired in accordance with their original terms and (iii) such longer period (not to exceed twelve months
following the Separation from Service (as defined in paragraph 4.C below) as may be provided by the Treasury Department in the final regulations addressing Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”);
provided, however, that the foregoing shall not be construed to cause an incentive stock option to fail to meet the statutory requirements of Section 422 of the Code. 
 B. If at any time prior to a Change in Control the Executive’s employment is terminated by the Company for any reason other than an Event of
Termination for Cause or if Executive resigns because of an Event of Termination for Good Reason, Executive shall be entitled to receive payment equal to (i) one year of Executive’s base salary (minus lawful withholdings) and
(ii) $15,000 (minus lawful withholdings) that Executive may use for benefit continuation under COBRA or for any other purpose (“Separation Benefits”). 
 C. If payable under paragraph 4.A, the Change of Control Severance Benefits shall be paid on the later of the 60th day after the effective date of Executive’s “separation from service” (within the meaning of Section 409A and the regulations issued thereunder) (“Separation from
Service”), or six months and one day after the Executive’s Separation from Service if the Executive is a “specified employee” (as that term is defined under Section 409A of the Code and the regulations issued thereunder)
(“Specified Employee”) at the time the Executive becomes entitled to Change of Control Severance Benefits under this Paragraph. If payable under paragraph 4.B, the Separation Benefits shall be paid periodically in installments over the
twelve months following the Executive’s Separation from Service, in accordance with the Company’s regular payroll practices, provided that no payment shall be made prior to the 60th day after the effective date of Executive’s Separation from Service or six months and one day after the Executive’s Separation from Service if the
Executive is a Specified Employee at the time the Executive becomes entitled to the Separation Benefits under this Paragraph. Notwithstanding the foregoing, no Change of Control Severance Benefits or Separation Benefits shall be due under this
Agreement unless (a) prior to the 60th day after the effective date of Executive’s separation from
service, Executive has signed a release agreement (“Release Agreement”) that the Company will provide in which Executive releases any possible claims against the Company and all of its parents, divisions, subsidiaries, affiliates, and
related companies, and their present and former agents, employees, officers, directors, attorneys, stockholders, plan fiduciaries, successors, and assigns; and (b) prior to the 60th day after the effective date of Executive’s separation from service, the seven day revocation period in the Release Agreement has expired without
Executive’s revocation. In the case of Separation Benefits, the Release Agreement shall also include a reasonable agreement to cooperate for a period of six months following the employment termination date and a mutual non-disparagement clause.

 5. General Provisions 
 A. This Agreement may not be assigned by Executive. This Agreement may be assigned in whole or in part by the Company to a successor in interest. Executive expressly 
  

 Page 5 

 agrees to honor and accept such assignment or other transfer and, on the consummation thereof, to attorn to the
Company’s assignee and to perform Executive’s duties and obligations under this Agreement for the benefit of the Company’s assignee as if the Company’s assignee were the Company. Executive further agrees that, on the consummation
of such assignment or other transfer, all references in this Agreement to the Company shall become and shall be deemed to be references to the Company’s assignee and the Company shall be relieved of all obligations under this Agreement.

 B. This Agreement shall be governed by, construed, and enforced in accordance with the internal, local laws, of the State of Texas
(without regard to conflicts of law rules) and the obligations of the Company and Executive shall be performable in the State of Texas. The Parties agree that proper jurisdiction and venue for any dispute arising under this Agreement are in state or
federal court in Harris County, Texas. 
 C. This Agreement contains the entire agreement between the Parties regarding any benefit Executive
may receive from any type of change of control or separation benefits (as defined in this Agreement or otherwise) at Tanox and supersedes and replaces all prior communications and agreements (oral or written) between Executive and the Company
regarding any benefit Executive may receive from any type of change of control or separation benefits (as defined in this Agreement or otherwise) at Tanox. This Agreement does not extinguish any previous written stock option agreements between
Executive and the Company; however, it modifies any previous written stock option agreements as provided in Paragraph 4 of this Agreement. Except as provided in this paragraph C, this Agreement does not extinguish any other agreements between
Executive and the Company. Except as expressly provided in this Agreement, no variation, modification, or change of this Agreement shall be binding upon either Party hereto unless set forth in a document duly executed by both Parties. 
 D. This Agreement is intended to express the Parties’ mutual intent, and irrespective of the Party preparing this document, no rule of construction
shall be applied against such Party, as both Parties have actively participated in the preparation and negotiation of this Agreement. 
 E.
No Party’s waiver of the other Party’s breach of any condition or provision of this Agreement shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. Failure on either
Party’s part to complain of any act or failure to act of the other Party or to declare the other Party in default, irrespective of how long such failure or default continues, shall not constitute a waiver by such Party of such Party’s
rights under this Agreement. 
 F. If any provision of this Agreement or the application thereof to any person or circumstance shall be
invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law. 

G. This Agreement shall inure to the benefit of and be binding on the undersigned Parties and their respective permitted successors and permitted
assigns. Whenever, in this instrument, a reference to any Party is made, such reference shall be deemed to include a reference to such Party’s permitted successors and permitted assigns; however, neither this 
  

 Page 6 

 Paragraph 5.G. nor any other portion of this Agreement shall be interpreted to constitute a consent to any assignment or
other transfer of this Agreement or any part hereof other than pursuant to and in accordance with this Agreement’s other provisions. 
 H. The prevailing Party in any dispute between the Parties to this Agreement, arising out of the interpretation, application, or enforcement of any provision of this Agreement, shall be entitled to recover all of its reasonable
attorneys’ fees and costs, whether suit be filed or not, including, without limitation, costs and attorneys’ fees related to or arising out of any arbitration, administrative proceedings, trial, or appellate proceedings, or petition for
review before any other court or administrative body. 
 I. Notwithstanding any other provision of this Agreement to the
contrary, Executive and the Company shall in good faith amend this Agreement to the limited extent necessary to comply with the requirements under Section 409A of the Code, and any regulations or other guidance issued thereunder, in order
to ensure that any amounts paid or payable hereunder are not subject to the additional 20% income tax thereunder while maintaining to the maximum extent practicable the original intent of this Agreement. 
 EXECUTED, in multiple counterparts, each of which shall have the force and effect of an original, on the Effective Date.

 SUPPLY OF WAFERS 

2.1 Wafer Specifications. Subject to the annual technology reviews as set forth in Section 2.10 below, the Wafers to be supplied under
this Agreement shall meet the specifications as agreed to by the Parties as set forth in Attachment A to this Agreement. MEMC shall maintain, in accordance with MEMC’s standard procedures, accurate records and data for any quality
testing done by or for MEMC of any Wafers purchased by Suntech hereunder and shall make such records and test data available to Suntech upon reasonable request. 
 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), Suntech 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 Suntech, 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 ten). 
 (i) For
Contract Years one through five, the quantities to be purchased by Suntech (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 *** of Suntech’s then current solar wafer demand (measured in Watts), provided that MEMC can accommodate *** of Suntech’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 Suntech quantities only up to *** 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 Suntech’s request for quantities in excess of *** of the Yearly Target Quantities in such years, and MEMC has agreed to supply such quantities.

  

 4 

 (ii) For Contract Years six through ten, 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 ten. Notwithstanding the foregoing, for Contract Years six through ten, the quantities to
be purchased by Suntech (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 *** of Suntech’s then current solar wafer demand (measured in Watts), provided that MEMC can accommodate 50% of Suntech’s actual then current solar wafer demand (as part of and pursuant to the rolling forecast
process of Section 2.2(e) hereof); provided, however, that in no event shall the Yearly Minimum Quantity to be purchased by Suntech in Contract Years six through ten exceed the Yearly Target Quantities set forth on Attachment B
hereto. For Contract Years six through ten, MEMC shall be obligated to supply Suntech 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 Suntech’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 ten exceed the Yearly Target Quantities set forth on Attachment B hereto unless such excess quantities have been requested by Suntech and agreed to
by MEMC (after the required three (3) years advance notice). 
 (iii) The Yearly Minimum Quantities may also be reduced,
for any Contract Year, pursuant to and in accordance with the provisions of Section 2.6. 
 (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 two Contract Years, the percentage mix between Multi Wafers and Mono Wafers supplied shall be at MEMC’s discretion. In Contract Years three through ten, MEMC shall change the percentage mix between Multi
Wafers and Mono Wafers based on Suntech’s request; provided that (i) Suntech has given at least one (1) year 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 ******** (***) of Wafers in any Contract Year as either
Multi Wafers or Mono Wafers, unless requested by Suntech 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
***** for Multi Wafers and an indicative average efficiency factor of ***** for Mono Wafers. The Parties agree that the actual average efficiency factor for both Multi Wafers and Mono Wafers experienced by Suntech 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
Suntech 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, Suntech shall
pay to MEMC via wire transfer of immediately available funds, within ten (10) days after being invoiced therefor, the difference between (A) the amount that would have been payable by Suntech during such Contract Year if Suntech 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 Suntech during such Contract Year for the actual volume of Watts purchased by Suntech 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-half percent (0.5%) 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, Suntech shall deliver to MEMC a forecast of the quantities of Wafers that Suntech 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 Suntech’s obligation to purchase some or all of Suntech’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. 
 2.3 Purchase Orders and Order Acknowledgements. Suntech 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 Suntech purchase
orders with a written MEMC Order Acknowledgement, which MEMC Order Acknowledgement will set forth those requested Suntech quantities for which MEMC can then confirm a quantity (which quantity may be a partial quantity of the Suntech purchase order)
and an estimated shipment calendar week. MEMC Order Acknowledgements shall reference the 

  

 6 

 
applicable Suntech purchase order. Until such time as MEMC has provided Suntech with an MEMC Order Acknowledgement for all Wafers requested on a Suntech
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, Suntech 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 Suntech, no additional or different terms or conditions contained in any quotation, sales order, acknowledgement form, purchase order or other communication from MEMC or Suntech shall be binding upon MEMC or Suntech,
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 Suntech purchase order and any MEMC Order Acknowledgement, the terms of
this Agreement shall apply. 
 2.4 MEMC Invoices. MEMC invoices shall reference the applicable Suntech purchase order and shall be
submitted for payment by MEMC to the Suntech accounts payable address specified in writing from time to time by Suntech. 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, MEMC shall pay, within thirty (30) days of being invoiced by Suntech therefor, fifty percent (50%) of all freight costs associated with sales of Wafers under this Agreement, with such invoices to
provide reasonable detail and supporting documentation for MEMC to confirm such freight costs. MEMC shall pack and ship Wafers in accordance with then-current industry standards and practice. 
 (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. Suntech shall furnish written shipping instructions to MEMC from time to
time, and such shipping instructions, if different from the last shipping instructions provided by Suntech to MEMC, shall take effect no earlier than seven (7) Business Days after receipt of such written instructions by MEMC. 
 (d) Shipment Date Change Requests. Suntech 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 
  

 7 

 (ii) If the shipment date change request notice is a delay request (a push out of
requested delivery date), Suntech 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, Suntech 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 Suntech pursuant to Section 2.5(d) affect, in any way, Suntech’s obligation to purchase some or all of Suntech’s Yearly
Minimum Quantity for any Contract Year, unless the provisions of Section 2.6(a) hereof would otherwise require a change to Suntech’s Yearly Minimum Quantities for that Contract Year or a subsequent Contract Year. 
 2.6 Missed Deliveries. 
 (a) Missed Deliveries Generally. 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 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) Suntech shall have the right, but not the obligation, which right must be exercised by
Suntech, 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 current Contract Year, to reduce the Yearly Minimum Quantity for such
subsequent Contract Year as follows. The Yearly Minimum Quantity for such subsequent Contract Year shall be reduced to an amount equal to the product of (I) the amount the Yearly Minimum Quantity for such subsequent Contract Year would have
otherwise been pursuant to the provisions of Section 2.2(a) multiplied by (II) the quotient of (x) the actual deliveries made by MEMC in the Contract Year (including the actual 

  

 8 

 
deliveries made by MEMC in the subsequent Contract Year intended as make up deliveries for the prior Contract Year) divided by (y) the amount of the
Yearly Minimum Quantity to be supplied by MEMC for such Contract Year pursuant to the provisions of Section 2.2(a); and 
 (B) If Suntech chooses to reduce its Yearly Minimum Quantity for such subsequent Contract Year pursuant to the provisions of Section 2.6(a)(i)(A), then a corresponding reduction in the Letter of Credit Amount shall be made pursuant to
the provisions of Section 3.1(c); and 
 (C) If Suntech chooses to reduce its Yearly Minimum Quantity for such
subsequent Contract Year pursuant to the provisions of Section 2.6(a)(i)(A), then MEMC shall also be required to return a pro-rata portion of the Retained Loan/Security Deposit Amount 
 (ii) Notwithstanding the foregoing, the Parties expressly agree and acknowledge that any Missed Deliveries hereunder or Wafer Delivery
Misses (defined in Section 2.6(b) below) shall not allow Suntech to terminate this Agreement, under Article IV, Section 2.13(c) or otherwise, unless (A) Section 4.4 hereof or (B) the last sentence of Section 4.2
would allow termination of this Agreement, but Missed Deliveries or Wafer Delivery Misses shall allow Suntech to proceed against MEMC for breach of the covenant to deliver Wafers on a timely basis. In no event shall delay of any shipment or any part
thereof by MEMC affect, in any way, Suntech’s obligation to purchase some or all of Suntech’s Yearly Minimum Quantity for any Contract Year unless the provisions of Section 2.6(a) hereof would otherwise require a change to
Suntech’s Yearly Minimum Quantity for that Contract Year or a subsequent Contract Year. 
 (b) Missed Deliveries in
Contract Years One through Three. In addition to the provisions of Section 2.6(a), only for Contract Years one, two and three, if MEMC is unable to deliver the Yearly Minimum Quantities pursuant to the provisions of Section 2.2(a), for
those three (3) Contract Years the following provisions shall also apply. If in any given half year period in the first three Contract Years (January through June or July through December), MEMC’s actual deliveries against committed
purchase orders (pursuant to MEMC’s standard Order Acknowledgement procedures in accordance with Section 2.3 hereof) are lower than such committed quantities (such delivery failure, a “Wafer Delivery Miss”), then MEMC
shall be required to offer Suntech the option of purchasing polysilicon from MEMC in an amount up to the Wafer Delivery Miss (with amounts of Wafers (Watts) converted to kilograms of polysilicon at MEMC’s experienced conversion rate for
the prior three (3) months) at the prices set forth on Attachment D. Suntech shall be provided with reasonable access (through an independent third party), upon request, to appropriate documentation of MEMC (or MEMC’s third party
outsource manufacturers) to allow Suntech to audit and verify MEMC’s experienced conversion rate(s) of kilograms of polysilicon to Wafers. The offer of any polysilicon pursuant to these provisions shall be made no later than ten (10) days
after the applicable measurement period (i.e., after one of the half year periods), with a reasonable delivery schedule for polysilicon to be agreed to by the Parties within 

  

 9 

 
five (5) Business Days thereafter. MEMC agrees to use commercially reasonable best efforts to delivery polysilicon as quickly as possible in the event
that MEMC is required to deliver polysilicon hereunder. If Suntech actually purchases polysilicon pursuant to the provisions of this Section 2.6(b), the decision to “count” such polysilicon sales against any requirement to deliver
Wafers or to makeup missed Wafer sales for the Contract Year shall be at MEMC’s discretion. If MEMC decides that such delivered polysilicon will be counted for purposes of fulfilling MEMC’s Wafer delivery obligation under
Section 2.2(a) hereof for the current Contract Year, then no changes will be made to the subsequent Contract Year’s Yearly Minimum Quantity, Letter of Credit or Loan/Security Deposit under Section 2.2(a) hereof 
 2.7 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 Suntech at the time when the Wafers have been made available by MEMC for pickup by Suntech at MEMC’s designated location and Suntech has been notified that such Wafers have been made available by MEMC
for pickup by Suntech. 
 2.8 Payment Terms; Delivery Terms; Freight Terms. 
 (a) MEMC shall issue an invoice to Suntech for each shipment of Wafers. All invoices will be in Dollars. Payment of invoices by Suntech
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-half percent (0.5%)
per month on the unpaid balance of any past due amount, unless prohibited by Law. If Suntech 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 Suntech 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 Suntech has been
failing to pay the purchase price when due for one or more shipments, and MEMC reasonably concludes that Suntech is in unsound financial condition and has notified Suntech 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 Suntech 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 Suntech 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 Suntech 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. Notwithstanding the foregoing Ex Works term of sale, MEMC shall select the carrier and shall negotiate with the carrier the transportation charges. Suntech shall pay all transportation
charges on a freight collect basis, but shall be permitted to bill MEMC for 

  

 10 

 
(50%) of all freight costs associated with sales of Wafers under this Agreement, pursuant to and consistent with Section 2.5(a). 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 Suntech. If any charges are
exempt from sales or use Tax liability, Suntech must provide MEMC with evidence of tax exemption acceptable to the relevant taxing authority. 
 2.9 Inspection. No later than within twenty (20) Business Days after receipt of each shipment of Wafers by Suntech under Section 2.7 hereof, Suntech shall inspect such Wafers for any defect (including compliance with
specifications), breakage (notwithstanding the foregoing Ex Works term of sale), overage or shortage. Suntech shall be deemed to have unconditionally accepted the entire shipment unless MEMC receives, within twenty five (25) Business Days after
Suntech’s receipt of the Wafers under Section 2.7 hereof, a written notice specifying the alleged defect, breakage, overage or shortage. If, however, the condition is not discoverable upon inspection of the Wafers, then the failure of
Suntech to provide MEMC with a written notice of claim within ninety (90) days after Suntech’s receipt of the Wafers under Section 2.7 hereof shall be a waiver of any claim relating to the Wafers, whether such claim be based in
contract, tort, strict liability or otherwise. MEMC will accept Wafers returned by Suntech and will pay transportation charges for such Wafers so long as the return was authorized in advance by MEMC and MEMC’s Returned Material Authorization
number is prominently marked on each shipping container. MEMC will not unreasonably withhold authorization for return requests where Suntech has provided MEMC with reasonable proof of Wafers not complying with specifications, or of shortages or
breakages, etc. Where MEMC has authorized a return of Wafers in accordance with the above procedures and MEMC’s standard returns process, MEMC shall, at its option: (a) replace the non-conforming or damaged Wafers, without any additional
expense to Suntech, within twenty (20) Business Days after receiving Suntech’s written notice, or (b) reimburse to Suntech the price paid for the non-conforming, missing or damaged Wafers, within twenty (20) Business Days after
MEMC has authorized a return of Wafers in accordance with the above procedures and MEMC’s standard returns process. 
 2.10 Annual
Technology Reviews; Quality Considerations. 
 (a) Annual Technology Reviews. Both MEMC and Suntech agree that,
starting no later than July 1, 2007, the Parties will conduct, at least annually, a review of the technology evolution for Wafers, polysilicon and solar cells. The implementation of any output from such technology reviews as it relates to
Wafers, Wafer manufacturing or polysilicon manufacturing shall be made by mutual agreement if possible; provided, however, that if the Parties are unable to reach agreement, any changes to be made to Wafers, Wafer manufacturing or polysilicon
manufacturing (or not made) shall be in MEMC’s sole reasonable discretion. The Parties also agree and acknowledge that continuous improvement efforts to Wafers and Wafer specifications (set forth in Attachment A hereto) will be made by
MEMC, and Suntech will cooperate with MEMC to accommodate reasonable changes to such specifications, such as changes in Wafer thickness within industry norms (e.g., Suntech may need to make reasonable changes in its cell production processes, such
as improved handling processes, to account for thinner Wafers). Similarly, Suntech may also request changes to Wafer specifications, such as 

  

 11 

 
Wafer dimensions, with appropriate notice. MEMC will make reasonable efforts to accommodate these requests. The primary Wafer size to be purchased and sold
pursuant to this Agreement is *** millimeter. Attachment A hereto also includes specification for *** millimeter Multi Wafers. The quantity of *** millimeter Multi Wafers to be supplied must be agreed to by MEMC, and MEMC shall use
commercially reasonable best efforts to supply Suntech with *** millimeter Multi Wafers if requested by Suntech. Any requested quantity of *** millimeter Multi Wafers that cannot be agreed to and supplied by MEMC shall instead be supplied as ***
millimeter Multi Wafers (on an equivalent number of Watts to be supplied basis). The Parties also agree to work together, if requested by the other Party, to determine if ***** wafers could be delivered by MEMC at the same prices (in any Contract
Year) as the price for Mono Wafers for that Contract Year (as set forth on Attachment B), and MEMC also agrees, if requested by Suntech, to provide Suntech with specifications for other types of wafers that MEMC could deliver at the same
prices (in any Contract Year) as the price for Wafers for that Contract Year as set forth on Attachment B. 
 (b)
Quality Considerations. The parties acknowledge that there are certain Wafer quality characteristics that, by their nature, may fall outside of the agreed upon specifications set forth in Attachment A hereto, but still may affect
product performance at the cell level or module level (i.e., the Wafers meet all specifications, but still cause significant deviation in performance or in Suntech’s production line). For those Wafer quality characteristics that are part of the
agreed upon specifications set forth in Attachment A, Section 2.11 addresses these issues. For those Wafer quality characteristics that are not part of the agreed upon specifications, but such characteristics still appear to cause
significant deviation in Wafer performance or in Suntech’s production line, the parties will jointly agree to address such non-specification Wafer quality characteristics on a continuous improvement basis or on a Wafer replacement basis after
joint analysis of Wafer characteristics can be correlated to any such issues (e.g., the Parties will work together to ensure that the Wafer breakage rate is within industry norms, assuming that Suntech’s processes (including handling) fall
within industry norms). 
 2.11 Representations and Warranties. MEMC represents and warrants that the Wafers delivered to Suntech
under this Agreement shall meet the specifications set forth in Attachment A hereto, and that Suntech shall obtain full and unencumbered title to all Wafers, free and clear of any and all rights of third parties, when title to the Wafers
passes to Suntech pursuant to and consistent with Section 2.7 hereof. 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. 
 2.12 Limitation of
Liability. 
 (a) Limitation. MEMC’s total liability, and Suntech’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 

  

 12 

 
of representations and warranties made under Section 2.11 hereof, shall be limited solely to Suntech’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, 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, Suntech shall be required to provide reasonable proof
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 Suntech 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. Suntech’s total liability,
and MEMC’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, shall be limited solely to MEMC’s actual direct
damages directly caused by any breach of contract by Suntech; provided, however, that such actual direct damages may not exceed MEMC’s lost profits as result of Suntech’s breach, plus any reasonable expenses or Losses MEMC may have
incurred before Suntech’s breach. 
 (b) Patents. If any suit is brought against Suntech for infringement of any
patent, now or hereafter existing in the United States or in any country where MEMC has furnished Wafers alleging that the Wafers or MEMC’s methods of manufacturing such Wafers infringe any such patent, MEMC shall, at its own expense, defend
and control the suit against these allegations, and shall pay any award of damages assessed against Suntech in the suit to the extent only that the damages are awarded in connection specifically with the alleged infringement, provided that
Suntech gives MEMC prompt notice in writing of the institution of the suit and, to the full extent of Suntech’s power to do so, MEMC is given information, reasonable assistance, and the sole authority to defend or settle the claim. MEMC shall
have no obligation under this Section 2.12(b) if the alleged infringement or violation is based upon (i) the compliance of MEMC with Suntech’s designs, specifications or instructions; or (ii) modifications of the Wafers after
they have been delivered to Suntech; or (iii) the use of Wafers in conjunction with other products not furnished by MEMC if the alleged infringement is primarily related to such other products. MEMC shall have no liability for infringement of
patents or violation of any third party proprietary rights except as expressly provided in this Section 2.12(b). 
 (c)
Technical Advice. If MEMC furnishes technical or other advice to Suntech, whether or not at Suntech’s request, with respect to processing, further manufacture, other use or resale of the Wafers, MEMC shall not be liable for, and Suntech
assumes all risk of, such advice and the results thereof, if such advice is followed by Suntech. Similarly, if MEMC offers technical or other advice to Suntech, whether or not at Suntech’s request, with respect to processing, further
manufacture, other use or resale of the Wafers, and Suntech declines to follow such advice, MEMC shall not be liable for, and Suntech assumes all risk of, such declination of advice and the results thereof. 
  

 13 

 2.13 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, resulting from a catastrophic event, including, without limitation, Acts of God, war, riot, fire, explosion, accident, flood or sabotage; lack of adequate fuel, power or single sourced raw materials; compliance with governmental
requests, Laws, regulations, orders, action or national defense requirements; embargoes or acts of civil or military authorities; 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 Suntech of any such Force Majeure Event within fourteen (14) days of such 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 Suntech 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, except as may be permitted by Section 2.13(c). 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. 
 (c) If MEMC has suffered a Force Majeure Event and is unable to perform substantially all of its
obligations under this Agreement for twelve (12) months or more after suspension of its performance after the occurrence of a Force Majeure Event, if the Parties mutually agree, then Suntech and MEMC may mutually terminate this Agreement.
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.

 (d) If Suntech has suffered a catastrophic Force Majeure Event and is unable to perform substantially all of its
obligations under this Agreement (including under committed purchase orders pursuant to Section 2.3 or to purchase Yearly Minimum Quantities under Section 2.2(a)) for six (6) months or more, MEMC and Suntech shall, in good faith, try
to reach an accommodation whereby MEMC could allow Suntech to temporarily reduce its obligations under committed purchase orders pursuant to Section 2.3 or under Section 2.2(a), with the understanding that Suntech would be expected to
resume its purchases of Wafers under this Agreement at the levels required by Section 2.2(a) as soon as commercially practicable, and in any event no later than twelve (12) months after the occurrence of the catastrophic Force Majeure
Event. 
 2.14 Noncompete in Favor of MEMC. 
 (a) Suntech understands that MEMC shall be entitled to protect and preserve the going concern value of its business to the extent
permitted by Law and that MEMC would not have entered into this Agreement absent the provisions of this Section 2.14. 

  

 14 

 
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
MEMC in advance of engaging in any activities, Suntech shall not, and each shall cause each of its affiliates and Subsidiaries to not, directly or indirectly, engage in any Restricted Suntech 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 Suntech Business, (B) soliciting any customer or prospective customer of MEMC anywhere in the world to purchase any products or
services which compete with those provided by MEMC and (C) assisting any Person in any way to do, or attempt to do, anything prohibited above; provided, however, that the ownership by Suntech after July 6, 2006 of up to a *********
(***) interest in any Person in a Restricted Suntech Business shall be permitted; and provided, further, that the continued ownership by Suntech as of July 6, 2006 of an interest in any company in a Restricted Suntech Business shall be
permitted. 
 (b) If, at the time of enforcement of the covenants contained in this Section 2.14 (the
“Restrictive Suntech 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, Suntech has determined and hereby acknowledges that the Restrictive Suntech Covenants are reasonable in terms of duration, scope and area restrictions. Suntech acknowledges that both MEMC and Suntech have been
doing business throughout the world. 
 (c) If Suntech or any of its affiliates or Subsidiaries breaches, or threatens to
commit a breach of, any of the Restrictive Suntech 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 Suntech Covenants specifically enforced by any court of competent jurisdiction, it being agreed that any breach or threatened breach of the Restrictive Suntech Covenants would cause irreparable injury to MEMC and that money damages would
not provide an adequate remedy to MEMC; and 
 (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 Suntech Covenants. 
 2.15 Noncompete in Favor of Suntech. 
 (a) MEMC understands that Suntech shall be entitled to protect and preserve the going concern value of its business to the extent permitted by Law and that Suntech would not have entered into this Agreement absent the
provisions of this Section 2.15. 

  

 15 

 
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
Suntech 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 Suntech anywhere in the world to purchase any products or
services which compete with those provided by Suntech and (C) assisting any Person in any way to do, or attempt to do, anything prohibited above; provided, however, that the ownership by MEMC after July 6, 2006 of up to a **********
(***) 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 2.15 (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 Suntech 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, Suntech 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 Suntech 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
Suntech and that money damages would not provide an adequate remedy to Suntech and 
 (ii) the right and remedy to require
such Person to account for and pay over to Suntech 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. 

ARTICLE III 
 LOAN/SECURITY DEPOSIT AND
LETTER OF CREDIT 
 3.1 Loan/Security Deposit. To induce MEMC to invest in additional polysilicon production and wafer manufacturing
capacity, Suntech agrees to loan MEMC, per the schedule 

  

 16 

 
set forth on Attachment C hereto, the amount of $625.0 million (the “Loan/Security Deposit”), as such amount may be adjusted pursuant
to Section 2.6(a) hereof, as a means of securing Suntech’s obligations to MEMC, which Loan/Security Deposit shall be repaid by MEMC, without interest, up to the amount of $606.3 million (97% of the aggregate Loan/Security Deposit amount,
such retained amount of $18.7 million, as such amount may be adjusted pursuant to Section 2.6(a) hereof, the “Retained Loan/Security Deposit Amount”), according to the repayment schedule set forth on Attachment C hereto,
unless Suntech 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 Suntech under Section 2.2(a) hereof against MEMC’s obligation to repay the Loan/Security Deposit. 
 (a) In any Contract Year when Suntech is required to pay MEMC a portion of the Loan/Security Deposit per the schedule set forth on Attachment C, payment by Suntech to MEMC shall be made, in full, no later than the fifth Business Day
of the applicable Contract Year; provided, however, that in connection with the Loan/Security Deposit amount to be paid by Suntech to MEMC for the first Contract Year, twenty five percent (25%) of the Loan/Security Deposit amount to be
paid by Suntech to MEMC for that first Contract Year shall be paid to MEMC fifteen (15) days after the date of this Agreement, and seventy five percent (75%) of the Loan/Security Deposit amount to be paid by Suntech 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 Suntech per the schedule set forth on Attachment C, payment by MEMC to Suntech 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 Suntech 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 Suntech 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
Suntech 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 Suntech’s “take or pay” obligations under Section 2.2(a) hereof. Accordingly, the Parties have agreed that Suntech will be required 

  

 17 

 
to deliver to MEMC, no later than the fifth Business Day of each Contract Year, an irrevocable Letter of Credit drawn on the New York, New York branch of the
Bank of China (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 sixth
Business Day of the subsequent Contract Year. If, in any Contract Year, MEMC instead requires that the LC Bank be a United States bank (i.e., not a United States branch of the Bank of China), then MEMC will pay for the incremental cost of having a
Letter of Credit on the Bank of China confirmed by such United States bank on the Bank of China’s behalf. Suntech may, in its discretion, use quarterly or half-year revolving Letters of Credit to cover the Letter of Credit Amount during any
respective Contract Year; provided, however, 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 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 an equal split between Multi Wafers and Mono 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 an equal split between Multi Wafers and Mono
Wafers), less the cumulative net amount of the Loan/Security Deposit then held by MEMC; and 
 (iii) In Contract Year
three through Contract Year ten, 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 equal split between Multi Wafers and Mono Wafers), 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 2.6(a)(i)(A), the Letter of Credit Amount will also be
adjusted upward or downward consistent with the provisions of this Section 3.1(c). 
  

 18 

 ARTICLE IV 
 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. 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 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 2.13(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 Suntech has failed to pay a Purchase Shortfall to MEMC within ten (10) 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 Suntech in accordance with the notice provisions of Section 7.4, to immediately terminate this
Agreement if: 
 (i) Suntech 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) Suntech 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 2.6 and Section 3.1(c) 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 2.6 and Section 3.1(c) hereof) no later than the ninth (9th) Business Day after receiving such written notice. 
  

 19 

 4.4 Termination by Suntech. 
 (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 2.6 hereof) for three (3) consecutive Contract Years, then, no later than thirty (30) days after the end of
such third consecutive Contract Year, Suntech may provide written notice to MEMC that Suntech 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 Suntech 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. 
 (b) If Suntech would have the right to terminate this Agreement pursuant to Section 4.4(a), but Suntech does not provide written notice of such intent to terminate to MEMC within the prescribed time frames of
Section 4.4(a), then Suntech 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, Suntech 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 2.6 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 2.11 (subject to
the time limits of Section 2.9 and Section 5.3), Section 2.12, 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 Suntech pursuant to Section 4.2 or Section 4.4(a), MEMC shall return the balance of Loan/Security Deposit to Suntech within thirty
(30) days of the termination. 
 ARTICLE V 
 INDEMNIFICATION 
 5.1 Indemnification Generally. Subject to Section 2.12, Suntech 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 Suntech’s breach of its
representations, warranties or covenants in this Agreement. Subject to Section 2.12, MEMC shall indemnify and defend Suntech 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 MEMC’s breach of its representations, warranties or covenants in this Agreement. 
  

 20 

 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 (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 Suntech 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. 
  

 21 

 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 compounded annually (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 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 

CONFIDENTIAL INFORMATION 
 6.1
Confidential Information; Public Disclosure.

existence of or the details of this Agreement and any trade secrets or other proprietary information it obtains with respect to Suntech during or after the term of this Agreement except as expressly permitted hereunder, and that it will treat all
such information as confidential and will use such information only for carrying out the purposes of this Agreement; provided, however, that MEMC will not be obligated to treat as confidential any information acquired by it that is either
known to the general public or to the industry, or known to, or in the possession of, MEMC prior to disclosure by Suntech, that is disclosed as required by Law, or that is independently developed by MEMC. The confidentiality obligations of MEMC
hereunder shall continue during the term of this Agreement and for a period of ten (10) years after termination.

or to the industry, or known to, or in the possession of, Suntech prior to disclosure by MEMC, that is disclosed as required by Law, or that is independently developed by Suntech. The confidentiality obligations of Suntech 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

applicable Law, including the requirements of the New York Stock Exchange or the United States Securities and Exchange Commission. 
 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
