against WEG and/or its customers; (ii) procure for WEG and/or its customers the right to continue using the 3.3 MW Design; or (iii) modify the NPS Design so that it becomes non-infringing, bearing the costs incurred by WEG to implement
such modifications.

 CONFIDENTIAL 
  

 (b) Without limiting the foregoing, the receiving Party agrees to employ with regard to the

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.

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.

 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
full force and effect and enforceable. 
 14.6 Language. All notices, certificates, correspondence or other communications under or
in connection with this Agreement, shall be in English. 
 14.7 Counterparts. This Agreement is made in three (3) original
copies, each having the same contents and the Parties have read and thoroughly understand the contents hereof and have hereby affixed their respective signatures and seals before witnesses. All counterparts shall constitute but one and the same
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.
