financial information required by Flextronics from time to time in order to make a proper assessment of the creditworthiness of Customer. 

3.7. Letter of Credit. Within forty-five (45) days of Flextronics’s request made at any time during the term of this Agreement,
Customer agrees to obtain and maintain a stand-by letter of credit or such other financial instrument mutually agreed upon by the parties on behalf of Flextronics to support Customer’s payment obligations set forth in this Agreement and to
minimize the financial risk to Flextronics for its performance of the Work under this Agreement. The stand-by letter of credit or other mutually agreed upon financial instrument shall be for a minimum period of time of three (3) months and
shall be for a total amount that is equal to the total value of the risks associated with Inventory, Special Inventory, and the accounts receivable from Customer. The calculation shall be based upon the forecast provided by Customer pursuant to
Section 3.1. The draw down procedures under the stand-by letter of credit or other mutually agreed upon financial instrument shall be determined solely by Flextronics. Flextronics will, in good faith, review Customer’s creditworthiness
periodically and may provide more favorable terms once it feels it is prudent to do so. In addition, Flextronics agrees that no letter of credit shall be required from Customer as long as Customer has promptly paid all invoices in accordance with
Section 3.5. 
  

	4.	MATERIALS PROCUREMENT; CUSTOMER RESPONSIBILITY FOR MATERIALS 

 4.1. Authorization to Procure Materials, Inventory and Special Inventory. Customer’s accepted purchase orders and forecast will constitute authorization for Flextronics to procure,

 4 

 
be subsequently increased or rescheduled, unless such subsequent increase or reschedule also conforms to the Flexibility Table. 

(b) All reschedules to push out delivery dates outside of the table in subsection (a) require Flextronics’s prior written
approval, which, in its sole discretion, may or may not be granted. If Customer does not request prior approval from Flextronics for such reschedules, or if Customer and Flextronics do not agree in writing to specific terms with respect to any
approved reschedule, then Customer will pay Flextronics the Monthly Charges for any such reschedule, calculated as of the first day after such reschedule for any Inventory and/or Special Inventory that was procured by Flextronics to support the
original delivery schedule that is not used to manufacture Product pursuant to an accepted purchase order within thirty (30) days of such reschedule. In addition, if Flextronics notifies Customer that such Inventory and/or Special Inventory has
remained in Flextronics’s possession for more than ninety (90) days since such reschedule, then Customer agrees to immediately purchase any affected Inventory and/or Special Inventory upon receipt of the notice by paying the Affected
Inventory Costs. In addition, any finished Products that have already been manufactured to support the original delivery schedule will be treated as cancelled as provided in Sections 5.3 and 5.4 below. 

(c) Flextronics will use reasonable commercial efforts to meet any quantity increases, which are subject to Materials and capacity
availability. All reschedules or quantity increases outside of the table in subsection (a) require Flextronics’s approval, which, in its sole discretion, may or may not be granted. If Flextronics agrees to accept a reschedule to pull in a
delivery date or an increase in quantities in excess of the flexibility table in subsection (a) and if there are extra costs to meet such reschedule or increase, Flextronics will inform Customer for its acceptance and approval in advance.

 (d) Any delays in the normal production or interruption in the workflow process caused by Customer’s changes to the
Specifications or failure to provide sufficient quantities or a reasonable quality level of Customer Controlled Materials where applicable to sustain the production schedule, will be considered a reschedule of any affected purchase orders for
purposes of this Section 5.2 for the period of such delay. In addition, Customer shall be responsible for costs related to adjusting foreign currency hedging contracts due to changes in cash flows resulting from such delays. 

(e) For purposes of calculating the amount of Inventory and Special Inventory subject to subsection (b), the “Lead Time”
shall be calculated as the Lead Time at the time of procurement of the Inventory and Special Inventory. 
 5.3.
Cancellation of Orders and Customer Responsibility for Inventory. 
 (a) Customer may not cancel all or any
portion of Product quantity of an accepted purchase order without Flextronics’s prior written approval, which, in its sole discretion, may or may not be granted. If Customer does not request prior approval, or if Customer and Flextronics do not
agree in writing to specific terms with respect to any approved cancellation, then Customer will pay Flextronics Monthly Charges for any such cancellation, calculated as of the first day after such cancellation for any Product or Inventory or
Special Inventory procured by Flextronics to support the original delivery schedule. In addition, if Flextronics notifies Customer that such Product, Inventory and/or Special Inventory has remained in Flextronics’s possession for more than
thirty (30) days since such cancellation, then Customer agrees to immediately purchase from Flextronics, such Product, Inventory and/or Special Inventory by paying the Affected Inventory Costs. In addition, Flextronics shall calculate the cost
or gain of unwinding any currency hedging contracts entered into by Flextronics to support the cancelled purchase order(s). Should the unwinding result in a loss to Flextronics, Customer agrees to cover such loss amount for Flextronics immediately
upon receipt of an invoice for such amount. Should the unwinding result in a gain to Flextronics, a credit note will be immediately issued to Customer. 
 (b) If the forecast for any period is less than the previous forecast supplied over the same period, that amount will be considered canceled and Customer will be responsible for any Special Inventory
purchased or ordered by Flextronics to support the forecast. 
 (c) Products that have been ordered by Customer and that have
not been picked up in accordance with the agreed upon shipment dates shall be considered cancelled and Customer will be responsible for such Products in the same manner as set forth above in Section 5.3(a). 

  
 5 

 (d) For purposes of calculating the amount of Inventory and Special Inventory subject to
subsection (a), the “Lead Time” shall be calculated as the Lead Time at the time of (i) procurement of the Inventory and Special Inventory; (ii) cancellation of the purchase order or (iii) termination of this Agreement,
whichever is longer. 
 5.4. Mitigation of Inventory and Special Inventory. Prior to invoicing Customer for the
amounts due pursuant to Sections 5.2 or 5.3, Flextronics will use reasonable commercial efforts for a period of thirty (30) days, to return unused Inventory and Special Inventory and to cancel pending orders for such inventory, and to otherwise
mitigate the amounts payable by Customer. Customer shall pay amounts due under this Section 5 within thirty (30) days of receipt of an invoice. Flextronics will ship the Inventory and Special Inventory paid for by Customer under this
Section 5.4 to Customer promptly upon said payment by Customer. In the event Customer does not pay within thirty (30) days, Flextronics will be entitled to dispose of such Inventory and Special Inventory in a commercially reasonable manner
and credit to Customer any monies received from third parties. Flextronics shall then submit an invoice for the balance amount due and Customer agrees to pay said amount within thirty (30) days of its receipt of the invoice. 

5.5. No Waiver. For the avoidance of doubt, Flextronics’s failure to invoice Customer for any of the charges set forth
in this Section 5 does not constitute a waiver of Flextronics’s right to charge Customer for the same event or other similar events in the future. 
  5.6. Delivery performance. On time delivery shall be measured and reported to Customer on a monthly basis. Orders shall be considered on time if they are shipped from one week earlier than
the scheduled shipment date up to one day after the scheduled shipment date. On-time delivery shall be the sole responsibility of Flextronics, except in cases where customer responsibility of inventory causes delays. If Flextronics can not meet the
on time delivery requirement for any order due to Flextronics’ failure to make a timely shipment, then Flextronics will ship that Order at Flextronics’ own expense via air transportation or other expedient means acceptable to Customer.

   

	6.	PRODUCT ACCEPTANCE AND EXPRESS LIMITED WARRANTY 

 6.1. Product Acceptance. The Products delivered by Flextronics will be accepted upon delivery in accordance with section 5.1 of this Agreement. If Products do not comply with the express

to either substitute a fully equivalent Product or process (as applicable) not subject to such injunction, modify such Product or process (as applicable) so that it no longer is subject to such injunction, or obtain the right to continue using the
enjoined process or Product (as applicable). In the event that any of the foregoing remedies cannot be effected on commercially reasonable terms, then, all accepted purchase orders and the current forecast will be considered cancelled and Customer
shall purchase all Products, Inventory and Special Inventory as provided in Sections 5.3 and 5.4 hereof. Any changes to any Products or process must be made in accordance with 

  
 8 

 
Section 2.2 above. Notwithstanding the foregoing, in the event that a third party makes an infringement claim, but does not obtain an injunction, the indemnifying party shall not be required
to substitute a fully equivalent Product or process (as applicable) or modify the Product or process (as applicable) if the indemnifying party obtains an opinion from competent patent counsel reasonably acceptable to the other party that such
Product or process is not infringing or that the patents alleged to have been infringed are invalid. 
 9.5. No Other
Liability. EXCEPT WITH REGARD TO A BREACH OF SECTIONS 9.1 AND 9.2 ABOVE OR SECTION 10.1 BELOW, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY “COVER” DAMAGES (INCLUDING INTERNAL COVER DAMAGES WHICH THE PARTIES

CONTRACT, TORT (INCLUDING THE POSSIBILITY OF NEGLIGENCE OR STRICT LIABILITY), OR OTHERWISE, EVEN IF THE PARTY HAS BEEN WARNED OF THE POSSIBILITY OF ANY SUCH LOSS OR DAMAGE, AND EVEN IF ANY OF THE LIMITED REMEDIES IN THIS AGREEMENT FAIL OF THEIR
ESSENTIAL PURPOSE. 
 THE FOREGOING SECTION 9 STATES THE ENTIRE LIABILITY OF THE PARTIES TO EACH OTHER CONCERNING
INFRINGEMENT OF PATENT, COPYRIGHT, TRADE SECRET OR OTHER INTELLECTUAL PROPERTY RIGHTS. 
  

	10.	MISCELLANEOUS 

 10.1.
Confidentiality. 
 (a) Each party shall refrain from using any and all Confidential Information of the disclosing
party for any purposes or activities other than those specifically authorized in this Agreement. Except as otherwise specifically permitted herein or pursuant to written permission of the party to this Agreement owning the Confidential Information,
no party shall disclose or facilitate disclosure of Confidential Information of the disclosing party to anyone without the prior written consent of the disclosing party, except to its employees, consultants, parent company, and subsidiaries of its
parent company who need to know such information for carrying out the activities contemplated by this Agreement and who have agreed in writing to confidentiality terms that are no less restrictive than the requirements of this Section.
Notwithstanding the foregoing, the receiving party may disclose Confidential Information of the disclosing party pursuant to a subpoena or other court process only (i) after having given the disclosing party prompt notice of the receiving
party’s receipt of such subpoena or other process and (ii) after the receiving party has given the disclosing party a reasonable opportunity to oppose such subpoena or other process or to obtain a protective order. Confidential Information
of the disclosing party in the custody or control of the receiving party shall be promptly returned or destroyed upon the earlier of (i) the disclosing party’s written request or (ii) termination of this Agreement. Confidential
Information disclosed pursuant to this Agreement shall be maintained confidential for a period of three (3) years after the disclosure thereof. The existence and terms of this Agreement shall be confidential in perpetuity. 

(b) Notwithstanding anything contained in this Section 10.1, a receiving Party may disclose the existence and terms of this
Agreement if such information is required by Law to be disclosed under applicable law, including without limitation pursuant to the rules and regulations promulgated by the United States Securities and Exchange Commission. 

10.2. Use of Flextronics Name is Prohibited. The existence and terms of this Agreement are Confidential Information and
protected pursuant to Section 10.1 above. Accordingly, Customer may not use Flextronics’s name or identity or any other Confidential Information in any advertising, promotion or other public announcement without the prior express written
consent of Flextronics. Flextronics may not use Customer’s name or identity or any other Confidential Information in any advertising, promotion or other public announcement without the express written consent of Customer. 

10.3. Entire Agreement; Severability. This Agreement constitutes the entire agreement between the Parties with respect to
the transactions contemplated hereby and supersedes all prior agreements and understandings between the parties relating to such transactions. If the scope of any of the provisions of this Agreement is too broad in any respect whatsoever to permit
enforcement to its full extent, then such provisions shall be enforced to the 

  
 9 

 
maximum extent permitted by law, and the parties hereto consent and agree that such scope may be judicially modified accordingly and that the whole of such provisions of this Agreement shall not
thereby fail, but that the scope of such provisions shall be curtailed only to the extent necessary to conform to law. 
 10.4.
Amendments; Waiver. This Agreement may be amended only by written consent of both parties. The failure by either party to enforce any provision of this Agreement will not constitute a waiver of future enforcement of that or any other
provision. Neither party will be deemed to have waived any rights or remedies hereunder unless such waiver is in writing and signed by a duly authorized representative of the party against which such waiver is asserted. 

10.5. Independent Contractor. Neither party shall, for any purpose, be deemed to be an agent of the other party and the
relationship between the parties shall only be that of independent contractors. Neither party shall have any right or authority to assume or create any obligations or to make any representations or warranties on behalf of any other party, whether
express or implied, or to bind the other party in any respect whatsoever. 
 10.6. Expenses. Each party shall pay
their own expenses in connection with the negotiation of this Agreement. All fees and expenses incurred in connection with the resolution of Disputes shall be allocated as further provided in Section 10.11 below. 

10.7. Insurance. Customer shall procure and/or maintain at its own expense the following insurance and will use
commercially reasonable efforts to do so within sixty (60) days of the Effective Date: (i) commercial general liability insurance (including coverage for bodily injury, personal injury, property damage, contractual liability, products and
completed operations) in an amount not less than One Million Dollars ($1,000,000.00) per occurrence; (ii) umbrella excess liability insurance in an amount not less than One Million Dollars ($1,000,000.00); and (iii) an errors and omissions
insurance policy which covers Customer’s obligations hereunder in an amount not less than One Million Dollars ($1,000,000.00). Such insurance shall be written by an insurance company with a Best’s rating of at least A-VIII who is licensed
to do business in all states of the United States. Customer shall furnish certificates of insurance and such other appropriate documentation (including evidence of renewal of insurance) evidencing all insurance coverage’s set forth in this
Section 10.6. Such certificates of insurance and other documentation shall name Flextronics and its officers, directors and employees as additional insured. Such certificates of insurance and other documentation shall contain a broad form
naming Flextronics and its officers, directors and employees as an additional insured. Customer will provide Flextronics with at least thirty (30) days prior written notice of any cancellation or material alteration of the insurance coverage
set forth in this Section 10.6. Failure by Flextronics to receive or request the aforementioned certificates of insurance and other documentation shall not represent a waiver of the requirements for insurance coverage set forth in this
Section 10.7 
 10.8. Force Majeure. In the event that either party is prevented from performing or is unable
to perform any of its obligations under this Agreement (other than a payment obligation) due to any act of God, acts or decrees of governmental or military bodies, fire, casualty, flood, earthquake, war, strike, lockout, epidemic, destruction of
production facilities, riot, insurrection, Materials unavailability, or any other cause beyond the reasonable control of the party invoking this section (collectively, a “Force Majeure”), and if such party shall have used its
commercially reasonable efforts to mitigate its effects, such party shall give prompt written notice to the other party, its performance shall be excused, and the time for the performance shall be extended for the period of delay or inability to
perform due to such occurrences. Regardless of the excuse of Force Majeure, if such party is not able to perform within ninety (90) days after such event, the other party may terminate the Agreement. 

10.9. Successors, Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their
respective successors, assigns and legal representatives. Neither party shall have the right to assign or otherwise transfer its rights or obligations under this Agreement except with the prior written consent of the other party, not to be
unreasonably withheld. Notwithstanding the foregoing, Flextronics may assign some or all of its rights and obligations under this Agreement to an affiliated Flextronics entity. 

10.10. Notices. All notices required or permitted under this Agreement will be in writing and will be deemed received
(a) when delivered personally; (b) when sent by confirmed facsimile; (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one (1) day after deposit
with a commercial overnight carrier. All communications will be sent to the addresses set forth above or to such other address as may be designated by a party by giving written notice to the other party pursuant to this section. 

  
 10 

 10.11. Disputes Resolution; Waiver of Jury Trial. 

(a) Except as otherwise provided in this Agreement, the following binding dispute resolution procedures shall be the exclusive means used
by the parties to resolve all disputes, differences, controversies and claims arising out of or relating to the Agreement or any other aspect of the relationship between Flextronics and Customer or their respective affiliates and subsidiaries
(collectively, “Disputes”). Either party may, by written notice to the other party, refer any Disputes for resolution in the manner set forth below. 
 (b) Any and all Disputes shall be referred to arbitration under the rules and procedures of Judicial Arbiter Group, Inc. (“JAG”), who shall act as the arbitration administrator (the
“Arbitration Administrator”). 
 (c) The parties shall agree on a single arbitrator (the
“Arbitrator”). The Arbitrator shall be a retired judge selected by the parties from a roster of arbitrators provided by the Arbitration Administrator. If the parties cannot agree on an Arbitrator within seven (7) days of
delivery of the demand for arbitration (“Demand”) (or such other time period as the parties may agree), the Arbitration Administrator will select an independent Arbitrator. 

(d) Unless otherwise mutually agreed to by the parties, the place of arbitration shall be Denver, Colorado, although the arbitrators may
be selected from rosters outside Denver. 
 (e) The Federal Arbitration Act shall govern the arbitrability of all Disputes. The
Federal Rules of Civil Procedure and the Federal Rules of Evidence (the “Federal Rules”), to the extent not inconsistent with this Agreement, govern the conduct of the arbitration. To the extent that the Federal Arbitration Act and
Federal Rules do not provide an applicable procedure, Colorado law shall govern the procedures for arbitration and enforcement of an award, and then only to the extent not inconsistent with the terms of this Section. Disputes between the parties
shall be subject to arbitration notwithstanding that a party to this Agreement is also a party to a pending court action or special proceeding with a third party, arising out of the same transaction or series of related transactions and there is a
possibility of conflicting rulings on a common issue of law or fact. 
 (f) Unless otherwise mutually agreed to by the parties,
each party shall allow and participate in discovery as follows: 
 (i) Non-Expert Discovery. Each party may
(1) conduct three (3) non-expert depositions of no more than five (5) hours of testimony each, with any deponents employed by any party to appear for deposition in Denver, Colorado; (2) propound a single set of requests for
production of documents containing no more than twenty (20) individual requests; (3) propound up to twenty written interrogatories; and (4) propound up to ten (10) requests for admission. 

(ii) Expert Discovery. Each party may select a witness who is retained or specially employed to provide expert testimony and an
additional expert witness to testify with respect to damages issues, if any. The parties shall exchange expert reports and documents under the same requirements as Federal Rules of Civil Procedure 26(a)(2) &(4). 

(iii) Additional Discovery. The Arbitrator may, on application by either party, authorize additional discovery only if deemed
essential to avoid injustice. In the event that remote witnesses might otherwise be unable to attend the arbitration, arrangements shall be made to allow their live testimony by video conference during the arbitration hearing. 

(g) The Arbitrator shall render an award within six (6) months after the date of appointment, unless the parties agree to extend
such time. The award shall be accompanied by a written opinion setting forth the findings of fact and conclusions of law. The Arbitrator shall have authority to award compensatory damages only, and shall not award any punitive, exemplary, or
multiple damages. The award (subject to clarification or correction by the arbitrator as allowed by statute and/or the Federal Rules) shall be final and binding upon the parties, subject solely to the review procedures provided in this Section.

 (h) Either party may seek arbitral review of the award. Arbitral review may be had as to any element of the award.

 (i) This Agreement’s arbitration provisions are to be performed in Denver, Colorado. Any judicial proceeding arising out
of or relating to this Agreement or the relationship of the parties, including without limitation any 

  
 11 

 
proceeding to enforce this Section, to review or confirm the award in arbitration, or for preliminary injunctive relief, shall be brought exclusively in a court of competent jurisdiction in the
county of Denver, Colorado (the “Enforcing Court”). By execution and delivery of this Agreement, each party accepts the jurisdiction of the Enforcing Court. 
 (j) Each party shall pay their own expenses in connection with the resolution of Disputes pursuant to this Section, including attorneys’ fees. 

(k) Notwithstanding anything contained in this Section to the contrary, in the event of any Dispute, prior to referring such Dispute to
arbitration pursuant to Subsection (b) of this Section, Customer and Flextronics shall attempt in good faith to resolve any and all controversies or claims relating to such Disputes promptly by negotiation commencing within ten
(10) calendar days of the written notice of such Disputes by either party, including referring such matter to Customer’s then-current President and Flextronics’s then current executive in charge of manufacturing operations in the
region in which the primary activities of this Agreement are performed by Flextronics. The representatives of the parties shall meet at a mutually acceptable time and place and thereafter as often as they reasonably deem necessary to exchange
relevant information and to attempt to resolve the Dispute for a period of four (4) weeks. In the event that the parties are unable to resolve such Dispute pursuant to this Subsection (k), the provisions of Subsections (a) through
(j) of this Section, inclusive, as well as Subsections (1), (m) and (n) of this Section shall apply. 
 (l) The
parties agree that the existence, conduct and content of any arbitration pursuant to this Section shall be kept confidential and no party shall disclose to any person any information about such arbitration, except as may be required by law or by any
governmental authority or for financial reporting purposes in each party’s financial statements. 
 (m) IN THE EVENT OF ANY
DISPUTE BETWEEN THE PARTIES, WHETHER IT RESULTS IN PROCEEDINGS IN ANY COURT IN ANY JURISDICTION OR IN ARBITRATION, THE PARTIES HEREBY KNOWINGLY AND VOLUNTARILY, AND HAVING HAD AN OPPORTUNITY TO CONSULT WITH COUNSEL, WAIVE ALL RIGHTS TO TRIAL BY
JURY, AND AGREE THAT ANY AND ALL MATTERS SHALL BE DECIDED BY A JUDGE OR ARBITRATOR WITHOUT A JURY TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW. 
 (n) In the event of any lawsuit between the parties arising out of or related to this Agreement, the parties agree to prepare and to timely file in the applicable court a mutual consent to waive any
statutory or other requirements for a trial by jury. 
 10.12. Even-Handed Construction. The terms and conditions
as set forth in this Agreement have been arrived at after mutual negotiation, and it is the intention of the parties that its terms and conditions not be construed against any party merely because it was prepared by one of the parties. 

10.13. Controlling Language. This Agreement is in English only, which language shall be controlling in all respects. All
documents exchanged under this Agreement shall be in English. 
 FLEXTRONICS CONFIDENTIAL 

10.14. Controlling Law. This Agreement shall be governed and construed in all respects in accordance with the domestic laws
and regulations of the State of Colorado, without regard to its conflicts of laws provisions; except to the extent there may be any conflict between the law of the State of Colorado and the Incoterms of the International Chamber of Commerce, 2000
edition, in which case the Incoterms shall be controlling. The parties specifically agree that the 1980 United Nations Convention on Contracts for the International Sale of Goods, as may be amended from time to time, shall not apply to this
Agreement. The parties acknowledge and confirm that they have selected the laws of the State of Colorado as the governing law for this Agreement in part because jury trial waivers are enforceable under Colorado law. The parties further acknowledge
and confirm that the selection of the governing law is a material term of this Agreement. 
 10.15. Counterparts.
This Agreement may be executed in counterparts. 

  
 12 

 IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed by their duly authorized
representatives as of the Effective Date.

 The following applies: 
  

	 	1.	During the ramp-up of the Customers product shipments (April 2009 -September 2009), Step 1 pricing will be used. 

 

	 	2.	Step quantities will be applied quarterly thereafter. The step quantities will be used as the basis for step pricing. 

 

	 	3.	A true-up will be performed at the end of each quarter, to apply the appropriate step price for that quantity. Overages in quantity will be applied to the next quarter
quantities. Additionally, a true up will be performed at the end of the first full year of production (April 2009 – April 2010) to make sure that customer has met the minimum quantity for step 1 pricing. Flextronics and customer will determine
an appropriate method to account for product changes from Raptor to Dually since Dually will only be built at one-half the quantity of Raptor. 

  

	 	4.	All scrap product will be purchased by the Customer, unless scrap was caused by Flextronics. Scrap will be shipped to customer and invoiced monthly.

  

	 	5.	The minimum quantity for each product must be reached each quarter except during the April 2009 – Sept 2009 ramp-up period. If the minimum quantity is not reached,
further cost recovery from the Customer will be required. 

  

	 	6.	Dually price will be quoted when RFQ is received. 

  

	 	7.	Pricing for new or replacement products will be quoted as required.

 MANUFACTURING RIGHTS. 

 

	1.	Ariane grants to Enphase a [***], fully paid, non-exclusive. non-sublicensable (except to have made for Enphase) right and license to place orders for Product
with, to purchase Product from and receive delivery of Product directly from Ariane’s suppliers and to use, sell, import, export, offer for sale, or otherwise transfer Product using the Licensed Technology and manufacturing information supplied
by Ariane to its suppliers for the applicable Product. The right and license shall only be exercisable by Enphase if Ariane fails to deliver a Product to Enphase, because (a) Ariane files for bankruptcy protection under Chapter 7 or Chapter 11
of the U.S. Bankruptcy Code or a receiver is appointed for Ariane and Ariane fails to deliver a Product to Enphase under this Agreement or a Purchase Order for a period of forty five (45) consecutive days after Enphase provides written notice
of such failure or (b) fails for any other reason whatsoever to deliver a Product to Enphase under this Agreement for a period of forty five (45) consecutive days after Enphase provides written notice of such failure. Failure to deliver
means failure to deliver the ordered quantities of acceptable Product within eight (8) weeks of the date of a Purchase Order. 

  

	2.	“Product” means Ariane’s PLM-1 ASIC. 

  

	3.	In the event that the conditions of Paragraph 1 have been satisfied and Ariane’s suppliers cease to manufacture Product, Ariane grants to Enphase a [***]
fully paid, non-exclusive, non-sublicensable (except to have made for Enphase) license to use the Licensed Technology for Product for the sole and limited purpose for Enphase to make, have made, use, sell, import, export, offer for sale, or
otherwise transfer Product. 

  

	4.	Ariane agrees that it will at all times keep Enphase apprised of the identity of its suppliers of Product until Enphase notifies Ariane that it no longer wishes to
purchase Product. Ariane agrees that it will notify each supplier of Product in writing of the existence of this Agreement with a copy to Enphase. 

  

	5.	The Parties agree that Ariane’s failure to notify its supplier that it has failed to deliver as that term is defined in Paragraph 1 would cause irreparable harm to
Enphase that cannot be adequately compensated at law. Accordingly, the parties agree that Enphase shall be entitled to seek injunctive relief requiring to Ariane or a receiver for Ariane to confirm in writing to Ariane’s supplier that a failure
to deliver has occurred.
