 3.3
Royalties. WEG shall pay Royalties to NPS for
[                    *                    ] NPS
2.X Units shipped by WEG under this Agreement (excluding units shipped due to warranty/replacement causes), provided that the Royalty on the Initial Turbine shall be paid after such unit is sold. After the payment of the Royalties for
[                    *                    ] NPS
2.X Units shipped by WEG,
[                    *                    ].
Along with each Royalty payment, WEG shall provide the following information to NPS in writing, signed by an authorized officer of WEG: the number of NPS 2.X Units shipped during the previous
[                    *                    ], the
date on which each such Unit was shipped, the destination of each such Unit (if known), the serial number of each such Unit, and such other information as NPS may reasonably request to verify the accuracy of the Royalties being paid. For all
purposes of this Agreement, an NPS 2.X Unit shall be considered to have been “shipped” upon Ex Works shipment of the hub, nacelle and generator for such unit.

 3.4 Payment Terms. All payments of Fixed Fee milestones pursuant to Section 3.2 above
shall be made by wire transfer in U.S. dollars and are due within twenty (20) days after completion of the applicable payment milestone. All payments of Royalties pursuant to Section 3.3 above shall be made by wire transfer in U.S. dollars
and are due
[                    *                    ]. Any
failure by WEG to pay any amounts owing to NPS under this Article 3 shall be deemed to be a material breach of this Agreement and shall entitle NPS to suspend performance hereunder and to the remedies set forth in Article 10. If WEG fails to make
any payment within twenty (20) days after the date such payment is due under this Agreement, in addition to all other rights which NPS may have at law, in equity or under this Agreement, interest shall accrue on the amount past due, including
any disputed amounts later resolved in favor of NPS, at a rate per annum of ten percent (10%), but in no event at a rate greater than permitted by any applicable Law. 

3.5 Taxes. The Parties agree that all public levies (taxes, charges, VAT, withholding payment, custom duties, etc.) imposed in
connection with the execution or closing of the Agreement shall be borne by NPS to the extent such levies are imposed in the U.S., and by WEG to the extent such levies are imposed in the Territory. Any withholding taxes or like charges which WEG
shall be required to withhold on remittance of any payment to NPS under the prevailing tax laws shall not be deducted from the amounts to be paid to NPS, and WEG shall be responsible for the payment of such taxes or charges or obtaining an exemption
from such taxes or charges, as appropriate. WEG shall promptly provide NPS with the evidence of its payment of or exemption from all taxes or charges. 

3.6 Audit Rights. At its own expense and upon at least ten (10) Business Days’ prior written notice, NPS may, using internal
personnel or a third party, inspect WEG’s facilities and records during business hours for the purposes of determining whether WEG is operating in compliance with the terms of this Agreement, including but not limited to confirming that WEG is
accurately reporting the number of NPS 2.X Units produced and shipped. Such inspection may include but shall not be limited to inspecting NPS 2.X Units in production at WEG’s factory or installed at customer sites, and examining purchase
orders, shipping documents, contracts, sublicenses or other agreements entered into by WEG for the marketing, sale or manufacture of NPS 2.X Units or any Components or otherwise in connection with this Agreement. In conducting such audit, NPS will
use all reasonable efforts to minimize any interference with the normal operations of WEG. All information provided to NPS in the course of conducting such audit shall be deemed to be Confidential Information of WEG. If any inaccuracies are
discovered during such audit implying any unpaid Royalties to NPS, WEG shall reimburse NPS for half of the auditing costs. Additionally, if NPS determines that there is a discrepancy between the number of NPS 2.X Units actually shipped and the
number of NPS 2.X Units as reported to NPS, WEG shall pay any unpaid Royalties owing thereon within five (5) Business Days of such discovery plus interest, as determined in accordance with Section 3.4 above, from the date such Royalty
payment was originally due.

against WEG and/or its customers; (ii) procure for WEG and/or its customers the right to continue using the NPS 2.1 and the NPS 2.X Technology; or (iii) modify the NPS 2.X Technology so that it becomes non-infringing, bearing the costs
incurred by WEG to implement such modifications. 
 6.5 Intellectual Property Challenge. Should WEG commence, become a party adverse
to NPS in, or prosecute, directly or indirectly, any declaratory judgment action or other action alleging the invalidity, unenforceability or non-infringement of any NPS Intellectual Property, then NPS shall provide written notice thereof to WEG

data, trade secrets, manufacturing processes and procedures, finances, organizational structure, business plan and strategies, sales, profitability, sales and marketing strategies, customers, sources of supply and business relationships.
Confidential Information shall also include comparable information that a Party may receive or has received belonging to others who do business with such Party. Notwithstanding the foregoing, it is understood and agreed that Confidential Information
shall not include any information which: 
 (a) is, at the time of disclosure by the disclosing Party hereunder, or thereafter becomes, a
part of the public domain or publicly known or available through no fault or negligence of the receiving Party; 
 (b) was otherwise in the
receiving Party’s lawful possession prior to disclosure by the disclosing Party, other than under an obligation of confidentiality; 

(c) was independently discovered or developed by the receiving Party, without use of the other Party’s Confidential Information, as can
be demonstrated by competent proof; or 

  
 21 

 (d) is lawfully disclosed to the receiving Party on a non-confidential basis by a third party who
is not in violation of an obligation of confidentiality to the disclosing Party relative to such information. 
 11.2 Identification and
Protection of Confidential Information. 
 (a) All information to be treated as Confidential Information subject to the provisions of
this Agreement shall be clearly marked as such (or, if communicated verbally, shall be verbally identified as confidential at the time of disclosure). Confidential Information may be disclosed by the receiving Party only to those employees of such
Party that have a “need to know” such information in order to perform their responsibilities under this Agreement on behalf of such Party. The receiving Party will, and will cause each of its employees to: 

(i) keep in utmost confidence all of the disclosing Party’s Confidential Information; 

(ii) not use any of the disclosing Party’s Confidential Information for any purpose other than the performance of this
Agreement; 
 (iii) not disclose any of the disclosing Party’s Confidential Information to any third party without the
disclosing Party’s prior written consent except in the distribution to customers and suppliers for usual and customary wind turbine business purposes, provided, that each such customer and supplier shall have first entered into a
confidentiality agreement in regard to such Confidential Information containing provisions protective of the disclosing Party’s rights therein that are at least as protective as those set forth herein; 

(iv) not cause or permit reverse engineering or copying of any of the disclosing Party’s Confidential Information or
decompilation or disassembly of any software programs which are part of such Confidential Information; and 
 (v) within
thirty (30) days after the termination of this Agreement for any reason, return to the disclosing Party or destroy all of the disclosing Party’s Confidential Information in the possession of the receiving Party, regardless of form and
including, without limitation, all copies, analyses, derivations and compilations of such Confidential Information and provide verification by a senior officer of the receiving Party that all such Confidential Information has been returned to the
disclosing Party or has been destroyed. 
 (b) Without limiting the foregoing, the receiving Party agrees to employ with regard to the
disclosing Party’s Confidential Information procedures no less restrictive than the strictest procedures used by the receiving Party to protect its own confidential information, and in no case less than a reasonable degree of care under the
circumstances. In particular, WEG (i) shall 

  
 22 

 
maintain all written NPS Confidential Information in secure locations which may only be accessed by WEG employees who are authorized to have access to such information in accordance with the
terms of this Article 11; (ii) shall maintain all electronic NPS Confidential Information on separate, secure servers and computers which are password-protected and which may only be accessed by WEG employees who are authorized to have access
to such information in accordance with the terms of this Article 11; and (iii) shall treat NPS Confidential Information involving magnets, generator stator modules and converter control boards like the most sensitive WEG Confidential
Information and shall not disclose such NPS Confidential Information to any third party other than experienced and qualified suppliers which will be providing such Components to WEG. The receiving Party shall promptly notify the disclosing Party of
any known unauthorized use or disclosure of the disclosing Party’s Confidential Information, and will cooperate with the disclosing Party in any litigation brought by the disclosing Party against third parties to protect its proprietary rights.

 (c) In the event that either Party is requested or required by a court, by governmental action or otherwise in connection with legal
proceedings (by oral question, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process) to disclose any Confidential Information of the disclosing Party, the receiving Party agrees to promptly
notify the disclosing Party in writing of such request or requirement so that the disclosing Party may seek a protective order or, in its discretion, waive compliance with these confidentiality provisions. 

(d) WEG acknowledges by signing this Agreement that the NPS Intellectual Property was not known by WEG prior to the execution of this
Agreement and constitutes Confidential Information of NPS. 
 (e) The obligations set forth in this Article 11 shall survive any termination
of this Agreement for a period of five (5) years. 
 Article 12 – Assignment 

12.1 Non-Assignment. This Agreement may not be assigned by either Party without the prior written consent of the other Party, such
consent not to be unreasonably withheld or delayed, provided, however that (a) either Party may assign this Agreement in whole, without the prior consent of the other Party, to a successor in ownership of all or substantially all of its
business assets to which this Agreement pertains, whether by sale of assets, merger, consolidation or otherwise, and (b) either Party may assign this Agreement in whole or in part, without the prior consent of the other Party, to any one or
more of its Affiliates (including, without limitation, an Affiliate formed by the amalgamation of such Party with another person or otherwise) so long as such Affiliate remains an Affiliate of such Party and provided that (i) the successor or
Affiliate agrees in writing to be bound by the terms of this Agreement and (ii) no such assignment shall place the non-assigning Party in a worse financial position by virtue of 

  
 23 

 
such assignment (including without limitation, with respect to taxes if the assignee is subject to the laws of a jurisdiction which different from the assigning Party). Any other purported
assignments shall void. This Agreement shall be binding upon any such permitted assignee and, subject to the restrictions on assignments herein set forth, inure to the benefit of the successors and assigns of each of the Parties hereto. 

Article 13 – Dispute Resolution

the initiation of any legal action or proceeding to resolve disputes between the Parties, in the event a dispute arises between WEG and NPS regarding, arising out of, relating to or in connection with this Agreement, its application, interpretation,
breach, termination, validity or invalidity thereof, or other related matter, or any other matter involving the Parties or any Affiliate thereof (each of the foregoing, a “Dispute”), upon the written request of either WEG or NPS (a
“Request”), the Parties shall use commercially reasonable efforts in good faith to settle the Dispute amicably. If a Dispute is not resolved within sixty (60) days after written notice of a Dispute by one Party to the other Party then
the provisions of Section 13.2 shall apply. 
 13.2 Arbitration. All Disputes that remain unresolved pursuant to
Section 13.1 shall be submitted to the International Court of Arbitration of the International Chamber of Commerce (the “ICC”) and shall be finally settled under the Rules of Arbitration of the ICC by a panel of three arbitrators.
Each Party shall appoint one arbitrator, and the two arbitrators so appointed shall jointly appoint a third arbitrator. In the event of the failure by any Party to appoint an arbitrator within thirty (30) days from the date of the receipt of
the notice from the other Party and/or failure by the two arbitrators appointed by the Parties to appoint the third arbitrator within a period of thirty (30) days, such arbitrator(s) shall be appointed by the ICC. The place of arbitration shall
be New York, New York, USA and the language of such arbitration shall be English. Both Parties shall bear equally the cost of the arbitration, unless otherwise determined by the arbitrators. All decisions of the arbitrators shall be final and
binding on both Parties and enforceable in any court of competent jurisdiction. Notwithstanding this, application may be made to any court for a judicial acceptance of the award or order of enforcement. In the event of judicial acceptance or an
order of enforcement, each Party expressly waives all rights to object thereto. 
 13.3 Provisional Relief. In connection with any
Dispute, each Party may seek and shall be entitled to receive provisional equitable relief from any court of competent jurisdiction, including without limitation provisional injunctive relief, provided that the final resolution of the Dispute shall
be through the arbitral tribunal appointed in accordance with Section 13.2. Each of WEG and NPS hereby submit to the exclusive jurisdiction of the courts located in New York, New York, USA with respect to any such claim for provisional relief,
provided that NPS may elect to bring such claim for provisional relief in any court in in the Territory which would have 

  
 24 

 
jurisdiction to hear such claim. Each Party waives any objection such Party might have to the laying of venue in such courts, including but not limited to objections based on lack of personal
jurisdiction, improper venue or inconvenience of the forum.

Article 9 – Force Majeure 
 9.1
Definition of Force Majeure. For purposes of this Agreement, “Force Majeure Event” means an event which is beyond the control of a Party, which is unforeseen, unavoidable and insurmountable, and which prevents total or partial
performance by such Party. Examples of Force Majeure include: 
 (a) natural disasters, including hurricanes, monsoons, lightning, flood,
earthquakes, fire, winds in excess of 40 meters per second, and severe weather; 
 (b) war, hostilities (whether war be declared or not),
piracy, invasions, mobilizations, requisitions, or embargoes; 
 (c) rebellions, revolutions, insurrections, or civil war, acts of
terrorism; 
 (d) contamination by radioactivity; 

(e) act or omission of any governmental agency or authority; 

(f) civil unrest, riot, agitation or vandalism; and 

(g) strikes or lock-outs, including strikes or lock-outs affecting any of the Parties’ subcontractors. 

9.2 Excuse from Performance; Notice. If either Party is rendered wholly or partially unable to perform its obligations under this
Agreement because of a Force Majeure Event, that Party shall be excused from whatever performance is affected by the Force Majeure Event to the extent so affected. The Party impacted by the Force Majeure Event shall promptly give the other Party
written notice describing the particulars of the occurrence. In no event shall the notice be more than five (5) Business Days after the affected Party becomes aware of such occurrence. Promptly thereafter and no later than twenty (20) days
after such occurrence, the non-performing Party shall give the other Party written notice estimating the expected duration and probable impact on the performance of such Party’s obligations hereunder, and continue to furnish timely regular
reports with respect thereto during the continuation of the Force Majeure Event. The suspension of performance shall be of no greater scope and of no longer duration 

  
 15 

 CONFIDENTIAL 
  

 
than is reasonably required by the Force Majeure Event. The non-performing Party shall exercise all reasonable efforts to mitigate or limit damages to the other Party. When the non-performing
Party is able to resume performance of its obligations under this Agreement, such Party shall give the other Party notice to that effect and shall promptly resume performance hereunder. 

9.3 Extended Force Majeure Event. If the Force Majeure Event continues for more than one hundred and twenty (120) days, the
Parties shall determine the extent of the influence of the Force Majeure Event upon the performance of obligations under this Agreement, to determine the future course of action. In particular, the Parties will determine: 

(a) whether the Agreement should be dissolved; or 

(b) whether the Party affected by the Force Majeure Event should be relieved the obligations that it is prevented from discharging by virtue
of the Force Majeure; or 
 (c) whether the Party which is affected by the Force Majeure Event should be permitted to delay the performance
of this Agreement by a duration equivalent to the duration of the Force Majeure.

 17 

 CONFIDENTIAL 
  

 
Agreement. Notwithstanding the foregoing, NPS shall not be required to return or destroy, as the case may be, any Developed Intellectual Property that
(i) [                    *

performance. 
 Article 11 – Confidentiality 

11.1 Definition. The term “Confidential Information” shall mean any and all information relating to the business or operations
of either Party not generally known by others, including, but not limited to, information relating to a Party’s products and proposed products, research and development programs and activities, Intellectual Property, technical information and
data, trade secrets, manufacturing processes and procedures, finances, organizational structure, business plan and strategies, sales, profitability, sales and marketing strategies, customers, sources of supply and business relationships.
Confidential Information shall also include comparable information that a Party may receive or has received belonging to others who do business with such Party. Notwithstanding the foregoing, it is understood and agreed that Confidential Information
shall not include any information which: 
 (a) is, at the time of disclosure by the disclosing Party hereunder, or thereafter becomes, a
part of the public domain or publicly known or available through no fault or negligence of the receiving Party; 

  
 18 

 CONFIDENTIAL 
  

 (b) was otherwise in the receiving Party’s lawful possession prior to disclosure by the
disclosing Party, other than under an obligation of confidentiality; 
 (c) was independently discovered or developed by the receiving
Party, without use of the other Party’s Confidential Information, as can be demonstrated by competent proof; or 
 (d) is lawfully
disclosed to the receiving Party on a non-confidential basis by a third party who is not in violation of an obligation of confidentiality to the disclosing Party relative to such information. 

11.2 Identification and Protection of Confidential Information. 

(a) All information to be treated as Confidential Information subject to the provisions of this Agreement shall be clearly marked as such (or,
if communicated verbally, shall be verbally identified as confidential at the time of disclosure). Confidential Information may be disclosed by the receiving Party only to those employees of such Party that have a “need to know” such
information in order to perform their responsibilities under this Agreement on behalf of such Party. The receiving Party will, and will cause each of its employees to: 

(i) keep in utmost confidence all of the disclosing Party’s Confidential Information; 

(ii) not use any of the disclosing Party’s Confidential Information for any purpose other than the performance of this
Agreement; 
 (iii) not disclose any of the disclosing Party’s Confidential Information to any third party without the
disclosing Party’s prior written consent except in the distribution to customers and suppliers for usual and customary wind turbine business purposes, provided, that each such customer and supplier shall have first entered into a
confidentiality agreement in regard to such Confidential Information containing provisions protective of the disclosing Party’s rights therein that are at least as protective as those set forth herein; 

(iv) not cause or permit reverse engineering or copying of any of the disclosing Party’s Confidential Information or
decompilation or disassembly of any software programs which are part of such Confidential Information; and 
 (v) within
thirty (30) days after the termination of this Agreement for any reason, return to the disclosing Party or destroy all of the disclosing Party’s Confidential Information in the possession of the receiving Party, regardless of form and
including, without limitation, all copies, analyses, derivations and compilations of such Confidential Information and provide verification by a senior officer of the receiving Party that all such Confidential Information has been returned to the
disclosing Party or has been destroyed. 

  
 19 

 CONFIDENTIAL 
  

 (b) Without limiting the foregoing, the receiving Party agrees to employ with regard to the
disclosing Party’s Confidential Information procedures no less restrictive than the strictest procedures used by the receiving Party to protect its own confidential information, and in no case less than a reasonable degree of care under the
circumstances. In particular, WEG (i) shall maintain all written NPS Confidential Information and all source code in secure locations which may only be accessed by WEG employees who are authorized to have access to such information in
accordance with the terms of this Article 11; (ii) shall maintain all electronic NPS Confidential Information and all source code on separate, secure servers and computers which are password-protected and which may only be accessed by WEG
employees who are authorized to have access to such information in accordance with the terms of this Article 11; (iii) shall treat NPS Confidential Information involving magnets, generator stator modules and converter control boards like the
most sensitive WEG Confidential Information and shall not disclose such NPS Confidential Information to any third party other than experienced and qualified suppliers which will be providing such Components to WEG; and (iv) shall treat all
source code like the most sensitive WEG Confidential Information and shall not disclose source code to any third party for any reason. The receiving Party shall promptly notify the disclosing Party of any known unauthorized use or disclosure of the
disclosing Party’s Confidential Information, and will cooperate with the disclosing Party in any litigation brought by the disclosing Party against third parties to protect its proprietary rights. 

(c) In the event that either Party is requested or required by a court, by governmental action or otherwise in connection with legal
proceedings (by oral question, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process) to disclose any Confidential Information of the disclosing Party, the receiving Party agrees to promptly
notify the disclosing Party in writing of such request or requirement so that the disclosing Party may seek a protective order or, in its discretion, waive compliance with these confidentiality provisions. 

(d) WEG acknowledges by signing this Agreement that the NPS Intellectual Property was not known by WEG prior to the execution of this
Agreement and constitutes Confidential Information of NPS. 
 (e) The obligations set forth in this Article 11 shall survive any termination
of this Agreement for a period of five (5) years. 
 Article 12 – Assignment 

12.1 Non-Assignment. This Agreement may not be assigned by either Party without the prior written consent of the other Party, such
consent not to be unreasonably withheld or delayed, provided, however that (a) subject to Section 12.2 below, either Party may assign this 

  
 20 

 CONFIDENTIAL 
  

 
Agreement in whole, without the prior consent of the other Party, to a successor in ownership of all or substantially all of its business assets to which this Agreement pertains, whether by sale
of assets, merger, consolidation or otherwise, and (b) either Party may assign this Agreement in whole or in part, without the prior consent of the other Party, to any one or more of its Affiliates (including, without limitation, an Affiliate
formed by the amalgamation of such Party with another person or otherwise) so long as such Affiliate remains an Affiliate of such Party and provided that (i) the successor or Affiliate agrees in writing to be bound by the terms of this
Agreement and (ii) no such assignment shall place the non-assigning Party in a worse financial position by virtue of such assignment (including without limitation, with respect to taxes if the assignee is subject to the laws of a jurisdiction
which different from the assigning Party). Any other purported assignments shall void. This Agreement shall be binding upon any such permitted assignee and, subject to the restrictions on assignments herein set forth, inure to the benefit of the
successors and assigns of each of the Parties hereto.

breach, termination, validity or invalidity thereof, or other related matter, or any other matter involving the Parties or any Affiliate thereof (each of the foregoing, a “Dispute”), upon the written request of either WEG or NPS (a
“Request”), the Parties shall use commercially reasonable efforts in good faith to settle the Dispute amicably. If a Dispute is not resolved within sixty (60) days after written notice of a Dispute by one Party to the other Party then

other Party and/or failure by the two arbitrators appointed by the Parties to appoint the third arbitrator within a period of thirty (30) days, such arbitrator(s) shall be appointed by the ICC. The place of arbitration shall be New York, New
York, USA and the language of such arbitration shall be English. Both Parties shall bear equally the cost of the arbitration, unless otherwise determined by the arbitrators. All decisions of the arbitrators shall be final and binding on both Parties
and enforceable in any court of competent jurisdiction. Notwithstanding this, application may be made to any court for a judicial acceptance of the award or order of enforcement. In the event of judicial acceptance or an order of enforcement, each
Party expressly waives all rights to object thereto. 
 13.3 Provisional Relief. In connection with any Dispute, each Party may seek
and shall be entitled to receive provisional equitable relief from any court of competent jurisdiction, including without limitation provisional injunctive relief, provided that the final resolution of the Dispute shall be through the arbitral

elect to bring such claim for provisional relief in any court which would have jurisdiction to hear such claim. Each Party waives any objection such Party might have to the laying of venue in such courts, including but not limited to objections
based on lack of personal jurisdiction, improper venue or inconvenience of the forum.

proceeding to enforce rights under this Agreement, the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees.

the specific purpose for which it is given.

 14.3 Entire Agreement. This Agreement, including all Schedules and Annexes, together
with the Mutual Confidentiality Agreement between the Parties dated November 1, 2012, constitutes the entire agreement of the Parties with respect to the subject matter hereof, and supersedes all previous agreements by and between the Parties
as well as all proposals or term sheets, oral or written, and all negotiations, conversations or discussions heretofore had between the Parties related to the subject matter of this Agreement. The Parties expressly acknowledge and agree that this
Agreement supersedes the terms of Section 2.6 (NPS 3.X Option) of that certain Technological Know-How Transfer Agreement for NPS 2.X dated March 20, 2013 between the Parties, and that such section is no void and of no further force or
effect. 
 14.4 No Waiver; Remedies. No failure on the part of either Party to exercise, and no delay in exercising, any right, power
or privilege hereunder shall operate as a waiver thereof or a consent thereto; nor shall any single or partial exercise of any such right, power or privilege preclude any other of further exercise thereof or the exercise of any other right, power or
privilege. The remedies herein provided are cumulative and not exclusive of any remedies provided by applicable law. 
 14.5
Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect, that provision shall be limited or eliminated to the minimum extent necessary so that this Agreement shall otherwise remain in

 14.6 Language. All notices, certificates, correspondence or other communications under or
in connection with this Agreement, shall be in English.

Agreement. 
 14.8 Survival. Articles 10,11,13 and 14 and Section 8.2 any other provision of this Agreement where the context
requires, as well as any rights or obligations otherwise accrued hereunder (including but not limited to any accrued payment obligations) shall continue to bind the Parties notwithstanding the termination or expiry of this Agreement. 

14.9 Costs and Expenses. Except as otherwise expressly provided herein, each Party shall bear its own costs and expenses, including
without limitation any fees payable to its advisors, in connection with the negotiation, preparation and execution of this Agreement. 

14.10 No Agency. The Parties agree that nothing in this Agreement shall be in any manner interpreted to constitute an agency or
partnership for and on behalf of any other Party and the relationship between the Parties is as a principal to principal and on an arm’s length basis. Except as otherwise expressly agreed to, nothing contained herein shall confer, on any Party,
the authority to incur any obligation or liability on behalf of the other Party or bind the other.
