sell and transfer, the Consideration Shares, and the Purchaser can transfer legal ownership of the Consideration Shares, in all cases free and clear from any and all Liens, free from all other
rights exercisable by or claims by third parties and free from any contractual or legal restrictions on transfer (other than those under this Agreement and under the Joint Venture Agreement). Upon Closing the Purchaser will transfer good and valid
title to the Consideration Shares to the Company, free and clear from all Liens (other than those under this Agreement and under the Joint Venture Agreement), free from all other rights exercisable by or claims by third parties and free from any
contractual or legal restrictions on transfer (other than those under this Agreement and under the Joint Venture Agreement). Other than those under this Agreement and under the Joint Venture Agreement, there are no outstanding subscriptions,
options, warrants, puts, calls, agreements, understandings, claims or other commitments or rights of any type or other securities (i) requiring the issuance, sale, transfer, repurchase, redemption or other acquisition of the Consideration
Shares, (ii) restricting the transfer of the Consideration Shares, or (iii) relating to the voting of the Consideration Shares. 

(d) Investment Intent. The Purchaser understands that the Issued Shares are “restricted securities” and have not been
registered under the Securities Act or any applicable state securities law and is acquiring the Issued Shares as principal for its own account and not with a view to or for distributing or reselling such Issued Shares or any part thereof in
violation of the Securities Act or any applicable state securities law, has no present intention of distributing any of such Issued Shares in violation of the Securities Act or any applicable state securities law and has no direct or indirect
arrangement or understandings with any other Persons regarding the distribution or resale of such Issued Shares (this representation and warranty not limiting the Purchaser’s right to sell the Issued Shares pursuant to a registration statement
covering Issued Shares or otherwise in compliance with applicable federal and state securities laws) in violation of the Securities Act or any applicable state securities law; provided, however, that by making the representations herein, the
Purchaser does not agree to hold any of the Issued Shares for any minimum period of time and reserves the right, subject to the provisions of this Agreement and the Registration Rights Agreement, at all times to sell or otherwise dispose of all or
any part of such Issued Shares pursuant to an effective registration statement under the Securities Act or under an exemption from such registration and in compliance with applicable foreign, federal and state securities laws. The Purchaser does not
presently have any agreement, plan or understanding, directly or indirectly, with any Person to distribute or effect any distribution of any of the Issued Shares (or any securities which are derivatives thereof) to or through any person or entity.

 (e) Purchaser Status. At the time the Purchaser was offered the Issued Shares, it was, and as of the date hereof it is, an
“accredited investor” as defined in Rule 501(a). 
 (f) Experience of the Purchaser. The Purchaser, either alone or
together with its Representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Issued Shares, and has so evaluated
the merits and risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Issued Shares and, at the present time, is able to afford a complete loss of such investment. 

  
 - 13 - 

 (g) General Solicitation. The Purchaser is not purchasing the Issued Shares as a result
of any advertisement, article, notice or other communication regarding the Issued Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or
general advertisement 
 ARTICLE IV 

INDEMNIFICATION 
 4.1
Survival of Representations and Warranties. The representations and warranties of the Parties hereto contained Article III in this Agreement shall survive the Closing a period of twelve (12) months from the Closing Date.
Notwithstanding the forgoing: the Fundamental Representations shall survive the Closing for a period of three (3) years from the Closing Date. For the avoidance of doubt, to bring a claim for indemnification under this Agreement, an Indemnified
Party need only provide written notice to the Indemnifying Party before the expiration of the applicable survival period, notwithstanding that resolution of such claims for indemnification may occur after expiration of such survival period. 

4.2 Indemnification. 

(a) The Company agrees to indemnify, defend and hold harmless the Purchaser and its Affiliates and their respective successors and permitted
assigns, partners, members, shareholders, directors, officers, employees, agents and other representatives (collectively, the “Purchaser Indemnified Parties”) from and against any and all Losses that are actually incurred as
a result of (i) any inaccuracy in or breach of any of the representations and warranties made by the Company in Section 3.1 of this Agreement or (ii) any breach of, or failure by the Company to perform any of the Company’s
covenants, agreements or other obligations contained in this Agreement. 
 (b) The Purchaser agrees to indemnify, defend and hold harmless
the Company and its Affiliates and their respective successors and permitted assigns, partners, members, shareholders, directors, officers, employees, agents and other representatives (collectively, the “Company Indemnified
Parties”, and together with the Purchaser Indemnified Parties, the “Indemnified Parties”) from and against any and all Losses that are actually incurred as a result of any of (i) any inaccuracy in or breach
of any of the representations or warranties made by the Purchaser in Section 3.2 of this Agreement or (ii) any breach of, or failure by the Purchaser to perform any of the Purchaser’s covenants, agreements or other obligations
contained in this Agreement. 
 4.3 Limitations on Liability. 

(a) For any claims of the Indemnified Parties under Sections 4.2(a)(i) and 4.2(b)(i), as applicable, subject to
Section 4.3(b), the Party from whom indemnification is sought (the “Indemnifying Party”) shall not be liable (i) for any individual occurrence, event, circumstance, act or omission where the Loss relating
thereto, arising out of or resulting therefrom, is less than US$50,000 (the “Threshold Amount”), (ii) for any Losses unless the aggregate amount of all Losses (excluding any Losses less than the Threshold Amount) of the

  
 - 14 - 

 
applicable Indemnified Parties exceeds one percent (1%) of the Total Issued Share Value (the “Aggregate Basket Amount”), in which case the Indemnifying Party shall
only be liable for such Losses in excess of the Aggregate Basket Amount, and (iii) for Losses in excess of five percent (5%) of the Total Issued Share Value (the “Indemnity Cap”). 

(b) For any claims of the Indemnified Parties under Sections 4.2(a)(ii) or 4.2(b) (ii), as applicable, or any claims for
indemnification resulting from or arising out of any breach of the Fundamental Representations, the aggregate amount of liability of the Indemnifying Party under this Agreement shall be limited to one-hundred percent (100%) of the Total Issued
Share Value. 
 (c) No Party shall be liable under this Article IV for any Losses based upon or arising out of any in accuracy in or breach
of any of the representations or warranties it makes under this Agreement if the other Party (or an Affiliate thereof) had knowledge of such inaccuracy or breach prior to the Closing. 

(d) In calculating the amount of any Losses payable to an Indemnified Party hereunder, the amount of the Losses (i) shall not be
duplicative of any other Loss for which an indemnification claim has been made, (ii) shall be computed net of any amounts actually recovered by such Indemnified Party (the “Third Party Indemnification Amount”) under any
other indemnification agreements, understanding or similar arrangements other than this Agreement with respect to such Losses (net of any costs and expenses incurred in obtaining such recovery), and (iii) shall be computed net of any amounts
actually recovered by such Indemnified Party under any insurance policy with respect to such Losses (net of any costs and expenses incurred in obtaining such insurance proceeds). If the Indemnifying Party pays an Indemnified Party for a claim and
subsequently insurance proceeds or the Third Party Indemnification Amount, as the case may be, in respect of such claim is collected by such Indemnified Party, then such Indemnified Party promptly shall remit the insurance proceeds (net of any costs
and expenses incurred in obtaining such insurance proceeds) or the Third Party Indemnification Amount, as the case may be, up to the amount paid by the Indemnifying Party to such Indemnified Party. For the purpose of this Section 4.3(d),
from and after the Closing, MKC and its subsidiaries shall be deemed to be Company Indemnified Parties. 
 4.4 Claims for
Indemnification. 
 (a) Third-Party Claims. All claims for indemnification made under this Agreement resulting from,
related to or arising out of a third-party claim against an Indemnified Party shall be made in accordance with the following procedures. An Indemnified Party shall give prompt written notification (not more than 30 days after becoming aware of
any third party claim) to the Indemnifying Party of the commencement of any action, suit or proceeding relating to a third-party claim for which indemnification may be sought or, if earlier, upon the assertion of any such claim by a third party;
provided that the failure to so notify an Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party has been materially prejudiced thereby. Such notification shall
include a description in reasonable detail, to the extent known or on hand at the time, of the facts constituting the basis for such third-party claim, all relevant documentation with respect to such third-party claim (including any summons,
complaint, pleading, written 

  
 - 15 - 

 
demand or other document or instrument) and the amount of the Losses claimed. At any time after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the
Indemnified Party, assume control of the defense of such action, suit, proceeding or claim by acknowledging without qualification its indemnification obligations as provided in this Article IV in writing to the Indemnified Party and assuming
all liability for such claim for indemnification (without any reservation of rights). If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense at the reasonable expense of the
Indemnifying Party. The Party not controlling such defense may participate therein at its own expense. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the
defense thereof and shall have the right to settle such action, suit, proceeding or claim; provided, however, (i) the Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior
written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed), and (ii) the Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior
written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement does not impose injunctive or equitable relief on the Indemnified Party or its Affiliates and includes a
complete release of the Indemnified Party and its Affiliates without prejudice. 
 (b) Procedure for Claims. An Indemnified
Party wishing to assert a claim for indemnification under this Article IV which does not involve a third-party claim shall deliver to the Indemnifying Party a notification in accordance with Section 7.4. Except to the
extent otherwise expressly stated in a written notice, if any, delivered by the Indemnifying Party within thirty (30) days following receipt of the notification, the Indemnifying Party shall be deemed to have not contested that the Indemnified
Party is entitled to receive any portion or all of the Losses claimed in such notification or is otherwise entitled to indemnification with respect to the matter described in the notice. If the Dispute relating to such notification is not
resolved within 90 days following the delivery of the notification, the Indemnifying Party and the Indemnified Party shall each have the right to submit such Dispute in accordance with the provisions of Section 7.8. 

4.5 Sole and Exclusive Remedy. From and after the Closing, except with respect to claims for equitable relief, including, without
limitation, specific performance, made with respect to breaches of any covenant or agreement contained in this Agreement, the rights provided to the Parties under this Article IV shall be the sole and exclusive remedies of the Indemnified
Parties with respect to claims under this Agreement or otherwise relating to the transactions contemplated hereby.
 4.6 Specific
Performance. In the event of a breach by the Company or by the Purchaser of any of their obligations under this Agreement and notwithstanding the provisions of this Article IV and Section 7.8, the Company or the Purchaser, as
the case may be, will be entitled to specific performance of its rights, injunctive relief and other equitable remedies under this Agreement. The Parties hereof agree that monetary damages would not provide adequate compensation for any Losses
incurred by reason of a breach by any Party of any of the provisions of this Agreement and hereby further agree, in the event of any action for specific performance, injunctive relief or other equitable remedies in respect of such breach, to waive
and not assert the defense that a remedy at law would be adequate.

 ARTICLE V 

OTHER AGREEMENTS OF THE PARTIES 

5.1 Legends; Transferability. 

(a) The Purchaser agrees to the imprinting, so long as is required by this Section 5.1, of a legend on any of the Issued Shares
in the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF
ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO
THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. 
 (b) Certificates evidencing the
Issued Shares shall not contain any legend (including the legend set forth in Section 5.1(a)), (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any
sale of such Issued Shares pursuant to Rule 144, (iii) if such Issued Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to
such Issued Shares and without volume or manner-of-sale restrictions, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
Commission). The Company agrees that following such time as such legend is no longer required under this Section 5.1(b), it will, as soon as reasonably practicable but in no event later than seven (7) Business Days following the
delivery by the Purchaser to the Company or the Company Transfer Agent of a certificate representing the Issued Shares issued with a restrictive legend, deliver or cause to be delivered to the Purchaser a certificate representing such shares that is
free from all restrictive and other legends. Any fees associated with the issuance of an opinion or the removal of legends pursuant to this Section 5.1(b) shall be borne by the Company. The Company may not make any notation on its
records or give instructions to the Company Transfer Agent that enlarge the restrictions on transfer set forth in this Section 5.1. Certificates for the Issued Shares subject to legend removal hereunder shall be transmitted by the
Company Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with The Depository Trust Company as directed by the Purchaser. 

5.2 Acknowledgment. The Company acknowledges that its obligations under the Transaction Documents are unconditional and absolute and
not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against the Purchaser and regardless of the dilutive effect that such issuance may have on the
ownership of the other shareholders of the Company. 

  
 - 17 - 

 5.3 Furnishing of Information; Public Information. The Company shall use its reasonable
best efforts to be and remain in compliance with the periodic filing requirements imposed under the Commission’s rules and regulations, including the Exchange Act, and any other applicable laws or rules, and thereafter shall timely file such
information, documents and reports as the Commission may require or prescribe under Section 13 or 15(d) (whichever is applicable) of the Exchange Act. If the Company is not required to file such reports during such period, it will, upon the
request of the Purchaser, make publicly available such necessary information for so long as necessary to permit sales pursuant to Rule 144 or Regulation S under the Securities Act, and it will take such further action as the Purchaser may reasonably
request, all to the extent required from time to time to enable the Purchaser to sell the Issued Shares without Registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 or Regulation S under the
Securities Act, as such Rules may be amended from time to time, or (b) any rule or regulation hereafter adopted by the Commission. From and after the Closing through the first anniversary of the date upon which the Purchaser does not own any
Issued Shares, the Company shall forthwith upon request furnish the Purchaser (i) a written statement by the Company as to whether it has complied with such requirements and, if not, the specifics thereof, (ii) a copy of the most recent
annual or quarterly report of the Company, and (iii) such other reports and documents filed by the Company with the Commission as the Purchaser may reasonably request in availing itself of an exemption for the sale of the Issued Shares without
registration under the Securities Act. 
 5.4 Integration. The Company shall not sell, offer for sale, solicit offers to buy or
otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Issued Shares to the Purchaser in a manner that would require the registration under the
Securities Act of the sale of the Issued Shares to the Purchaser or that would be integrated with the offer or sale of the Issued Shares for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval
prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction. 

5.5 Appointment of Directors. Prior to the Closing, the Purchaser shall cooperate with the Company to cause the MKC Board of Directors
to convene a meeting of the shareholders of MKC immediately after the Closing to appoint as directors and statutory auditor(s) of MKC the persons designated by the Company and so notified in writing to the Purchaser at least ten (10) Business
Days prior to the Closing. At the request of the Company, the Purchaser shall deliver to the Company a power of attorney appointing the Company as the attorneys-in-fact of the Purchaser to attend and vote at such meeting of shareholders on behalf of
the Purchaser, provided however, that, such power of attorneys shall be effective conditional upon the Closing. 
 5.6
Release of Directors and Statutory Auditor. The Parties shall cooperate with each other, and the Company shall cause the Company MEMC Shareholders to provide full cooperation to the Purchaser, to (x) cause MKC to deliver at the Closing a

directors of the Company. 
 5.9 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of
the Company, any other Person, that the Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or
arrangement in effect or hereafter adopted by the Company, or that the Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving the Issued Shares under the Transaction Documents or under any other
agreement between the Company and the Purchaser.

allowing any Disposition by the Major Shareholder during the Lock-Up Period pursuant to the lock-agreement by and between the Major Shareholder and the Underwriters, the covenant in this Section 5.17 shall be deemed to have been
automatically waived and the Purchaser shall be allowed to engage in a Disposition without any written consent from the Company, with such Disposition being on a pro rata basis with the Major Shareholder, based on the number of total outstanding
Ordinary Shares at such time; provided, further, that such waiver and permissible Disposition shall be limited solely to the extent of allowing the Purchaser to participate in the Disposition transaction by the Major Shareholder.

notice to the Company if the Purchaser is not then in material breach of any provision of this Agreement and there has been a material breach of any representation, warranty, covenant or
agreement made by the Company; or (y) the Company by written notice to the Purchaser if the Company is not then in material breach of any provision of this Agreement and there has been a material breach of any representation, warranty, covenant
or agreement made by the Purchaser in this Agreement, and in the case of either (x) or (y) above, such breach cannot be cured, or has not been cured, by the breaching Party within twenty (20) Business Days following the receipt by the
breaching Party of the non-breaching Party’s notice thereof, or (iii) by the Purchaser by written notice to the Company if the Closing has not been consummated at or before 5:00 p.m. (New York time) on September 30, 2014; provided,
however, that subject to Section 7.1(b), such termination will not affect the right of any Party to seek any and all remedies for any Losses incurred as a result of any breach by the other Party or Parties and that the provisions set

termination of this Agreement pursuant to Section 7.1(a)(iii) (or the failure of the transactions to be consummated as a result of such termination), and upon payment of the Termination Fee in accordance with this
Section 7.1(b), none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement. Solely for purposes of establishing the
basis of the amount thereof, it is agreed that the Termination Fee is a liquidated damage and not a penalty and is a reasonable measure of the damages that would be suffered by the Purchaser (including reputational damages). The Parties acknowledge

 For a period of six months from the First Six Months – [***]pcs / Month 

For a period of twelve months from the First Period – [***]pcs / Month 

For a period of twelve months from the Second Period – [***]pcs / Month 

Notwithstanding anything to the contrary, Samsung’s purchase requirements specified herein shall not apply for such quantities of Products
for a given period, if and to the extent that (a) the Products supplied by Supplier do not meet the Specifications, quality standards or cause quality issues, (b) Supplier does invoice Samsung for the Products with a price higher than the
price calculated by Samsung and communicated to Supplier in accordance with the procedure set-out in this Agreement and/or (c) Supplier fails to deliver the committed quantity of the required Products in accordance with the Delivery schedule.

 c. Samsung shall use its commercially reasonable efforts to prioritize [***] qualification. 

d. During and within two (2) years following the term of this Agreement, upon reasonable notice, Supplier shall have the right, at its
expense, to have a neutral third party audit the price calculations made by Samsung pursuant to Section 2.3 and to audit compliance with the requirements therein. Such audits shall be conducted no more than twice per year during term of this
Agreement and for six (6) months thereafter. Any such audit shall be conducted during regular business hours at Samsung’s offices and shall not interfere unreasonably with Samsung’s business activities. All information disclosed to
such neutral third party in connection with such audit shall be held by such party in strict confidence and shall not be disclosed by such party to any Third Party. The neutral third party shall report only the summary results of the audit to
Supplier and shall not disclose to Supplier and specific Samsung customer information. All such records shall be retained by Samsung for a period of at least three (3) years or longer if required by applicable laws. 

2.4 Terms of Payment. Unless mutually accepted Purchase Order or mutually agreed otherwise, Supplier shall invoice Samsung for each shipment of
Products upon delivery of such shipment to Samsung. Samsung shall pay the undisputed amounts payable to Supplier under this Agreement within [***] days after the date of receipt by Samsung of Supplier’s original invoice in complete and proper
form (which shall not precede the shipment date). Samsung may withhold payment of particular charges that Samsung disputes in good faith. The prices and terms of payment stated herein apply to all Products purchased hereunder. Samsung shall have no
obligation to honor invoices for Products at any increased price or additional charge, unless such item is agreed to in writing by Samsung. All payments shall be conditional upon Samsung’s acceptance of delivery of the Products.

Supplier shall allocate supplies of the Products to Samsung and the Samsung Affiliates and to its other customers in a manner that is fair and reasonable.

of Products to Samsung. Once such country of origin information has been provided to Samsung, Supplier shall also inform Samsung, through at least six (6) months prior notice, of any change in the country of origin status. 

  

	[***]	Indicates that text has been omitted which is the subject of a confidential treatment request. The text has been separately filed with the Securities and Exchange Commission. 

 Article 3 

Forecasting and Ordering Process; Delivery 

3.1 Forecasts. Samsung may provide Supplier on the last Business Day of each calendar month with a rolling forecast of Samsung’s expected order
volumes for the Products including the applicable Specifications covering a period of three (3) months starting one (1) month ahead of the date of such forecast (the “Order Forecast”). The actual order volume for the first month
of such Order Forecast shall not deviate from the Order Forecast and the actual order volume for the second month of the Order Forecast shall not deviate upwards or downwards by more than three percent (3%) from the Order Forecast for the
respective month (the “Guaranteed Order Forecast”). The Order Forecast for month three (3) shall be non-binding. 
 3.2 Purchase
Orders. 
 a. Samsung may issue Purchase Orders from time to time to Supplier. Purchase Orders shall be consistent with the lead times
and quantities in the binding portion of the Order Forecast as set forth in Section 3.1 above. Supplier shall respond to such Purchase Orders within five (5) Business Days of receipt of a Purchase Order with (i) full acceptance of
Purchase Order confirming the quantity, delivery date and delivery location(s); (ii) partial acceptance of Purchase Order suggesting different quantity, delivery date or delivery location(s); or (iii) rejection of the Purchase Order. If a
Purchase Order is partially accepted, the Parties may agree to a revised Purchase Order, which if mutually confirmed shall become an accepted Purchase Order. Supplier shall fulfill all such Purchase Orders and shall use commercially reasonable
efforts to reduce the lead-time during the term of this Agreement. Even if Supplier issues a notice rejecting the Purchase Order, if Supplier delivers Products to Samsung, such Products shall be deemed to be delivered pursuant to the terms of this
Agreement. If Supplier believes any shipment may not be delivered on schedule (and without waiver of any rights by either Party), Supplier must provide advance notification to Samsung, along with proposed solutions and recovery plans. 

b. Samsung may at any time before Supplier’s acceptance of a Purchase Order, by written notice, make changes in or cancel such Purchase
Order, subject to Samsung’s obligations with respect to the lead times and quantity commitments in the binding portion of the Order Forecast. After acceptance of a Purchase Order by Supplier, Samsung may request in writing changes in or
cancellation of such Purchase Order, and Supplier shall use its commercially reasonable efforts to comply with Samsung’s request. If any such change is likely to cause an increase in the cost of or time required for performance of
Supplier’s obligations pursuant to this Agreement, Supplier shall notify Samsung of such increase and the Parties shall discuss an equitable adjustment in the price or delivery schedule or both. 

c. In addition to any other provision contained herein for the cancellation or termination of this Agreement, Samsung may cancel any Purchase
Order or part thereof, solely at its convenience, in whole or in part, by written notice to Supplier. Upon such cancellation, Samsung shall be liable for Products already manufactured or in the process of manufacture but under no circumstances shall
Samsung or the Samsung Affiliates be liable for Supplier’s commitments or production arrangements in excess of the amount, or in advance of the time, necessary to meet Samsung’s delivery schedule specified in a Purchase Order. Samsung may
cancel or reschedule any past-due deliveries on Purchase Orders without any liability whatsoever unless delayed shipment is mutually agreed in advance. If only a portion of the Products are available for shipment to meet the delivery date, Supplier
shall notify Samsung as soon as practicable and ship the available Products unless otherwise directed by Samsung. Samsung may return any unauthorized under-shipment or any over-shipment or any portions
thereof, at Supplier’s expense. 
 3.3 Delivery. 

a. The obligation of Supplier to meet the delivery dates, specifications, and quantities, as set forth herein, is of the essence in this
Agreement. If any of Supplier’s deliveries fail to meet schedule, Samsung, without limiting its other rights or remedies, may direct expedited routing and charge any 

 
excess cost incurred thereby to Supplier. Except to the extent that Samsung has requested or authorized advance partial shipments, Products that are delivered in advance of schedule are delivered
at the sole risk of Supplier and may, at Samsung’s option, be returned at Supplier’s expense for proper delivery and/or Samsung may withhold payment therefore until the date that the Products are actually scheduled for delivery. No
substitution of materials or accessories may be made to Products without Samsung’s written consent. 
 b. If requested by Samsung,
Supplier shall update Samsung with the status of each delivery promptly. 
 c. All deliveries, unless otherwise stated in the accepted
Purchase Order, shall comply with the delivery terms otherwise mutually agreed in writing. Supplier acknowledges that the Products and any related materials or information provided along with the Products may be subject to export control laws and
regulations of the United States or any other countries, and Supplier agrees to comply with all applicable export statues, rules and regulations of any governmental authority having jurisdiction and shall obtain all necessary permits, licenses and
consents of governmental authorities necessary for the manufacture, sale, export, import or other performance contemplated by this Agreement. In addition, Supplier shall provide Samsung with all information necessary, including but not limited to,
proper Product classification and ECCN numbers under applicable export control laws and regulations, to allow Samsung to export Products or Samsung products incorporating Products. Title to any returnable or re-useable containers or packages in
which the Products are delivered, including Hybox and [***] shall be allowed within Samsung’s specifications. Samsung agrees that it shall return Hybox containers to Supplier at no cost to Supplier. Supplier shall be responsible for performing
maintenance on such containers. 
 3.4 Late Delivery. 

a. TIME IS OF THE ESSENCE WITH RESPECT TO ALL DELIVERIES AND PERFORMANCE. 

b. Supplier will use its best efforts to expedite delivery of delayed Products and will be responsible for all expediting costs. 

3.5 Packing, Marking and Shipment. Unless otherwise specified by Samsung in writing, Supplier shall pack and mark the Products so as to reasonably
ensure that the Products reach Samsung at its ultimate destination in a secure fashion. Secondarily, unless otherwise agreed to in writing by Samsung or requested by Samsung either through the Purchase Order or otherwise, Supplier shall attempt to
secure the lowest transportation rates to meet carrier requirements and shall prepay all shipping charges. Damage discovered after transfer of title that is determined to be a result of faulty packaging or handling by Supplier shall be
Supplier’s responsibility. Unless otherwise provided, the price stated in this Agreement shall include all charges and expenses with respect to containers, packing and crating, and for transportation to the mutually agreed destination.
Notwithstanding, it is understood that the pricing set forth in Section 2.3a above is for the price of the Products only and does not include transportation. Purchase Order number, Harmonized Tariff Codes and Samsung part numbers, if
applicable, must be shown on all packing slips and invoices and on all packages, crates, and other containers. Each shipment must contain a packing slip showing the number of pieces in the shipment. Samsung’s count shall be accepted as correct
if any packing slip quantity is in dispute or the packing slip is omitted. In the event that there are any delays in the delivery of the Product(s) as a result of any regulatory requirements in connection with the Product packaging, Supplier shall
be fully liable for any costs, loss or damages associated with such delay. 
 3.6 Inspection and Product Changes 

a. Supplier shall conduct outgoing inspection of Products in accordance with procedures agreed between the Parties before delivery of such
Product to Samsung, and Samsung will be permitted to participate in such outgoing inspection. If any inspection or test is made on Supplier’s premises, 

  

	[***]	Indicates that text has been omitted which is the subject of a confidential treatment request. The text has been separately filed with the Securities and Exchange Commission. 

 
Supplier, without additional charge, shall provide reasonable facilities and assistance for the safety and convenience of Samsung’s representatives. Inspection may be performed, at
Samsung’s option, on an appropriate statistical sampling basis. Upon delivery of the Product at the location specified by Samsung, Samsung will have the right to conduct incoming inspection of such Product. 

b. Samsung shall notify Supplier of any shortages or other non-conforming Product. If Samsung rejects any Product based on non-conformance,
Samsung may, in addition to all its other rights and remedies at law or equity, exercise one or more of the following remedies: (i) return rejected Product for full credit at the Product price charged plus any transportation charges; or
(ii) accept a conforming part of any shipment; or (iii) have rejected Product replaced by Supplier at the Product price stipulated in this Agreement. This section does not apply to rejections based on defects, which are covered by the
Warranty section below. 
 c. Upon reasonable prior notice to Supplier, Samsung shall have the right, during normal business hours and at
its own expense, to participate in outgoing inspection of Products as set forth in Section 3.6a above. Supplier agrees to cooperate fully with such inspection. No inspection, approval or acquiescence by Samsung with respect to Product shall
relieve Supplier from any portion of its warranty obligation nor shall waiver by Samsung of any specification requirement for one or more items constitute a waiver of such requirements for remaining items unless expressly agreed by Samsung in
writing. The inspection rights stated above are notwithstanding prior payment therefor by Samsung. 
 d. Supplier shall comply with all
applicable requirements in the ISO 9001:2008 quality system standards and the ISO 14001:2004 environmental system standards, as replaced or renewed, or other quality assurance standards that are substantially equivalent and approved by Samsung.
Supplier shall also comply with Samsung’s Standard for Control of Substances with Environmental Impacts within Products (“Samsung Environmental Standards, 0QA-2049,” which will be provided to Supplier upon request) in controlling
environmentally hazardous substances. The Parties will work together to accelerate qualification of [***]. For the [***], the Parties agree that minimum [***]% [***] shall apply, but no additional discount will be acceptable in the years of 2014 and
2015. The parties agree to negotiate in good faith a new [***] for [***] from July 2015 forward. 
 e. Supplier shall give Samsung no less
than ninety (90) days prior written notice of any Product revision that may impact the Product’s operation, interchangeability with existing Products, appearance, life cycle or Samsung or Samsung’s customer(s) engineering/quality
approvals of any Products. Supplier shall, at the time of notification, provide Samsung with (i) a Product change number; (ii) a description of such change; (iii) reason for change; (iv) a description of the impact of such change
upon (A) reliability, (B) Product specifications, (C) form, fit or function; (v) proposed price impact (if any) and (vi) proposed effective date for such change and recommend implementation schedule therefore. Only upon
Samsung’s written approval of the change, may Supplier implement the change to Product. Notwithstanding the above, Supplier shall not change its production methods or conditions (which includes, but is not limited to, process changes, sourcing
changes, design changes, component stepping changes, geographical relocation of manufacturing site, drawing changes or process step discontinuance) in a manner that would alter the Product Specifications after the issuance of a Purchase Order and
before delivery of the ordered Product without the prior written consent of Samsung. Supplier shall inform Samsung in writing of all such planned changes. If Supplier makes any such above changes without Samsung’s prior written consent,
Supplier shall be responsible for any direct damages and loss caused by the failure of such Product used by Samsung. 
 3.7 Audit. Supplier shall
maintain and retain complete and accurate books and records relating to the production, packaging, storage and shipment of Product. Supplier shall also maintain and retain any other records required to be maintained under this Agreement or required
to be kept by any applicable laws. At any time during and within two (2) years following the term hereof, upon reasonable notice, Samsung will have the right to audit Supplier’s books, records, documents, reports and other materials related to
this Agreement for the sole purpose of verifying its compliance with the terms of this Agreement. Any such audit shall be conducted during regular business hours at Supplier’s offices and shall not interfere unreasonably with the
Supplier’s business activities. Such audit may be conducted by an independent auditor as designated by Samsung at Samsung’s

not be disclosed by the auditor to any Third Party. All such records shall be retained by Supplier for a period of at least three (3) years or longer if required by applicable laws. 

Article 4

 4.1 Warranty.
Supplier warrants to Samsung that (i) Products will at the time of delivery be free and clear of all liens and encumbrances, (ii) Supplier has all right, title and interest necessary to provide Samsung (and all those taking title or

of such Products; (b) repair such Products; or (c) replace the Products. Return of Products hereunder shall be at Supplier’s expense (including any expenses and penalties incurred by Samsung in recalling Products delivered to
Samsung’s customers). Delivery to Samsung of corrected or replaced Products shall also be at Supplier’s expense. Products corrected or replaced shall be subject to all warranty and indemnification provisions of this Agreement in the same
manner and to the same extent as Products originally delivered under this Agreement, provided that the remaining Warranty Period for such Products would be extended, if applicable, to be at least [***] days. All repairs costs including, but not
limited to, labor and parts shall be the full responsibility of the Supplier during the Warranty Period. EXCEPT AS SET FORTH IN THIS SECTION 4.1, SUPPLIER MAKES NO OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, WITH RESPECT TO THE PRODUCTS
AND SPECIFICALLY DISCLAIMS THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 
 4.2 Epidemic Failure. Unless mutually agreed
otherwise in writing, an “Epidemic Failure” shall mean a defect from which the same root cause has been established which affects more than [***] percent ([***]%) of Products supplied to Samsung for any given [***] days, provided that such
defect is caused solely by such Products and does not include failures or defects arising from the use of such Products not in accordance with the Product Specifications. If an Epidemic Failure occurs during a period of [***] from the date of
Samsung’s acceptance of delivery of the Products, then in addition to the standard warranty remedies provided in Section 4.1, Samsung may return all the Products from the same manufacturing lot that is the subject of the Epidemic Failure.
In addition, Supplier will, at Samsung’s discretion, reimburse Samsung for all actual and reasonable out-of-pocket expenses incurred by Samsung for the repair and replacement of defective Products from the manufacturing lot that is the subject
of the Epidemic Failure, including expenses associated with problem diagnosis, field and finished goods inventory repair or replacement. 
 4.3 RMA
Process. The Parties shall comply with the RMA process stipulated in the Products Schedule. If no RMA process is stipulated, the Parties agree to cooperate with each other for prompt but not later than 30 days from the Parties’ agreement on

 Article 5 

Product End-of-Life; Availability, Parts and Maintenance 

5.1 Supplier shall provide Samsung with no less than one (1) year prior written notice of its intent to no longer offer for sale any Product and shall

repair parts. 
 5.2 Supplier shall provide Samsung with full technical support for Products, including providing Samsung with manuals, drawings, plans and
other documentation, and shall make available any product upgrade, improvement or retrofit to Samsung at competitive cost. If during the manufacturing stage of the Product, Supplier has developed an improvement or advancement applicable to the
Product, Supplier shall inform Samsung promptly and incorporate such improvements or advancements into the Products currently in production with the consultation and approval of Samsung. 

Article 6 

Confidentiality 
 6.1
Confidentiality. Each Party hereto agrees not to use any Confidential Information of the other Party for any purpose, other than in performing its obligations hereunder, or disclose any Confidential Information of the other Party to any Third
Party for any purpose except as otherwise expressly authorized by this Agreement. Each Party hereto shall use the same degree of care, but no less than reasonable care, to avoid disclosure or use of the Confidential Information of the other Party as
such Party employs with respect to its own Confidential Information of like importance. The receiving Party will limit the disclosure of such Confidential Information to such employees or employees of its Affiliates with a legitimate need to know in
connection with this Agreement, provided that such employees are informed of the confidentiality obligations herein and are subject to written confidentiality agreements with confidentiality obligations no less restrictive as those set forth herein.
The receiving Party will be responsible for any improper disclosure or use of the disclosing Party’s Confidential Information by such receiving Party’s employees to whom it discloses such Confidential Information. 

6.2 Supplier Obligations. In addition to the confidentiality obligations under Section 6.1, Supplier shall: 

 

	 	(i)	keep the price and quantity terms of this Agreement and contents of Purchase Orders confidential; 

  

	 	(ii)	keep the manufacturing process of Products that are customized for Samsung confidential and shall not permit any third party’s access to the manufacturing facilities for such Products without Samsung’s prior
approval; 

  

	 	(iii)	not allow access to Samsung’s Confidential Information without Samsung’s prior approval to anyone, whether employed by Supplier or not, who it knows or reasonably suspects has close relationship with
Samsung’s competitors, whether through employment, consulting arrangement or otherwise; 

  

	 	(iv)	have all its departing employees who have had any access to Samsung’s Confidential Information return all confidential or proprietary information or trade secrets that they have culminated while employed by
Supplier. 

 6.3 Exceptions. The obligations of confidentiality set forth in this Agreement shall not apply to any part
of Confidential Information which: (i) is or has become published or otherwise available to the public other than by a breach of this Agreement any other duty of confidentiality by the receiving Party; (ii) rightfully received by the
receiving Party from a third party without confidential limitation; (iii) approved in writing for public release by the disclosing Party; (iv) known to the receiving Party prior to its first receipt of such Confidential Information from
the disclosing Party; or (v) independently developed by the receiving Party without use of or reference to such Confidential Information; or (vi) disclosed as required by law or the rules of any stock exchange on which a party’s
securities are listed. For the purpose of the above exceptions, disclosures which are specific shall not be deemed to be within the foregoing exceptions merely because they are embraced by general disclosures which fall within one of those
exceptions. Additionally, any combination of features shall not be deemed to be within the foregoing exceptions merely because individual features thereof are. 

6.4 Public Disclosure. Subject to any requirement by applicable law, regulation or legal process, the Parties agree not to disclose the existence of
this Agreement or any of the contents without the prior express written consent of the other Party; provided, however, that the Parties may disclose such information to their respective employees, officers, directors, consultants, contractors and
professional advisors (collectively, the “Representatives’) who strictly need to know such information in connection with the performance of this Agreement; provided further that each Party shall be liable for any failure of any of its
Representatives to abide by the confidentiality provisions of this Agreement as if such failure was the act or omission of such Party. In the event that a Party is required by applicable law, regulation or legal process to disclose any of such
information, such Party shall notify the other Party promptly to permit such other Party to seek measures to maintain the confidentiality of its Confidential Information; provided that such Party shall disclose only that portion of the Confidential
Information which such Party is legally required to disclose. 
 6.5 Term of Confidentiality. The provisions of this Article 6 will survive the
expiration or termination of this Agreement for five (5) years. 
 6.6 Return or Destruction. Upon the termination of this Agreement, or upon
the disclosing Party’s earlier request, the receiving Party will deliver to the disclosing Party (and will not recreate or deliver to anyone else) all of the disclosing Party’s Confidential Information that the receiving Party may have in
its possession or control; or upon the disclosing Party’s request, the receiving Party will destroy all Confidential Information of the disclosing Party in its possession, including all copies and confirm in writing that it has complied with
the obligations set forth in this paragraph. However, this provision under Section 6.6 will not apply to any Confidential Information of Supplier that is embedded in or a part of any of Product that is used or owned by Samsung under this
Agreement. 
 6.7 Use of Names and Trademarks. Supplier shall not make any oral or written statement or perform any act indicating that Samsung
endorses or approves, or has endorsed or approved Supplier or its work products. Nothing contained in this Agreement will be construed as conferring any right to use in advertising, publicity or other promotional activities any name, trade name,
trademark or other designation of a Party (including any contraction, abbreviation or simulation of any of the foregoing) without the prior written approval of such Party. 

6.8 IP Transfer or Assignment. Supplier may not assign or transfer to a Third Party any of its intellectual property materially related to
Supplier’s performance of its obligations herein without Samsung’s prior written approval. In case such assignment or transfer occurs, Supplier shall have such assignee or transferee provide a written certification of non-assertion to
Samsung that expressly covenants that it will not enforce or assert such intellectual property against either Supplier or Samsung. 

 Article 7 

Indemnification 
 7.1 Supplier shall
defend, indemnify and hold harmless Samsung and its Affiliates and their respective directors, officers, employees, agents, customers and distributors (collectively, the “Samsung Indemnitees”) from and against any and all Claims,
liabilities, damages, losses, judgments, authorized settlements, costs and expenses (including without limitation, reasonable attorney’s fees), (i) resulting from, arising out of or in connection with any alleged or actual intellectual
property infringement or misappropriation Claims raised by a third-party (including any Claim alleging that the manufacture, use and/or sale of any Product constitutes infringement or misappropriation of such third-party’s patent, trademark,
copyright, utility right, design right, know-how, trade secret or other intellectual property right to the extent attributable to Supplier), (ii) resulting from, arising out of or in connection with the delivery, condition, manufacture,
purchase, use, sale, import, distribution or other transfer of Products purchased hereunder, except to the extent solely caused by the gross negligence of Samsung (iii) a breach of any agreement, covenant, representation or warranty made by
Supplier in this Agreement, (iv) any damage to property and injuries (including death) to any persons resulting from, arising out of or in connection with Products purchased hereunder, or (v) the negligence, gross negligence, bad faith or
intentional or willful misconduct of Supplier, its Affiliates and their respective Representatives in the performance by Supplier such party of its obligations hereunder. 

7.2 In addition to the foregoing, should any Product become or in Supplier’s reasonable opinion be likely to become, the subject of any Claim for
infringement or misappropriation, Supplier shall, at Samsung’s option and Supplier’s expense, (a) use its best efforts to procure for Samsung the right to continue using Products, or (b) replace or modify Products so that it
becomes non-infringing while still providing substantially the same functionality. If the foregoing is not possible within a commercially reasonable time frame, then Supplier shall refund the full amount paid by Samsung and any Samsung Affiliate for
all such Product, without prejudice to any other remedies that are available to Samsung. 
 7.3 The foregoing provisions of this article shall be subject to
(i) prompt and proper notification by the Samsung Indemnitees to Supplier of any Claim covered under Section 7.1; provided, however, that the failure to provide such notice within a reasonable period of time shall not relieve Supplier of
any of its obligations hereunder except to the extent Supplier is prejudiced by such failure or delay; and (ii) prompt and proper cooperation from the Samsung Indemnitees to Supplier, at Supplier’s expense, to the extent necessary in the
defense of any such Claim. Supplier shall assume, at its cost and expense, the defense of such Claim through counsel selected by Supplier and reasonably acceptable to Samsung Indemnitees, except that Samsung Indemnitees may at their option and
expense select and be represented by separate counsel. Supplier may not settle any such Claim without Samsung Indemnitees’ written consent unless such settlement (a) includes a release of all covered Claims pending against the Samsung
Indemnitees; (b) contains no admission of liability or wrongdoing by the Samsung Indemnitees; and (c) imposes no obligations upon the Samsung Indemnitees (other than an obligation to cease use of any infringing item). 

7.4 Notwithstanding anything to the contrary, Supplier shall not be liable for Claims where (i) Product is based on a specific and detailed design
implementation supplied by Samsung and there is no non-infringing alternative, or (ii) the infringement arises directly from a modification of Product made by Samsung without Supplier’s consent, and such infringement would not have arisen
but for such modification. 
 Article 8 

Limitation of Liability

CLAIMS ARISING UNDER ARTICLES 6 AND 7 OR CLAIMS INVOLVING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, (I) IN NO EVENT SHALL ANY PARTY BE LIABLE TO THE OTHER FOR ANY LOSS OF REVENUE, LOSS OF ACTUAL OR ANTICIPATED PROFITS,

b. In the event of a Supplier Bankruptcy Event, Samsung may cancel this Agreement or any Purchase Order in whole or in part and may pursue any
further remedies available at law or in equity. No waiver by Samsung of a breach by Supplier of any provision of this Agreement shall constitute a waiver of any other breach or provision. All of Samsung’s rights and remedies hereunder shall be
cumulative and not exclusive.

the parties toward each other will cease, except Articles 1, 4, 5, 6, 7, 8, 9 and 10 shall survive expiration or termination of this Agreement.
