DISCRETE TECHNOLOGY DEVELOPMENT AGREEMENT 

THIS DISCRETE TECHNOLOGY DEVELOPMENT AGREEMENT (“Agreement”) is entered into as of April 1, 2015 by and between Polar Semiconductor,
LLC, a Delaware corporation headquartered in Bloomington, Minnesota (“PSL”); Sanken Electric Co., Ltd., a Japanese corporation headquartered in Saitama, Japan (“Sanken”). Such parties are singularly referred to herein as a
“Party” and collectively referred to as “Parties.” 
 WHEREAS, the Parties may, from time to time, cooperate in the development
of new technology of discrete semiconductor devices with the anticipation that such technology may be used by PSL to manufacture products for Sanken; and 

WHEREAS, the Parties wish to stipulate the terms and conditions that will apply to such technology development. 

NOW, THEREFORE, the Parties hereby agree as follows: 

1.    Development Activities. The Parties may, from time to time, agree upon certain technologies to be
developed pursuant to this Agreement. In such case, the Parties will cooperate to establish a discrete device process road map and agree upon the process development and enhancement activities necessary to implement such road map (the
“Development Activities”). The technology resulting from the Development Activities, together with derivatives thereof, is referred to herein as the “Technology.” 

2.    Development Team. The Parties have established a Discrete Device Process Development Steering Committee
(hereinafter the “Team”) to agree upon and monitor the Development Activities. The Team will be comprised of an equal number of members from each Party representing both the business and technology segments of each Party. Unless otherwise
agreed by the Parties, the Team will not exceed eight (8) members. It is anticipated that the Team will meet on a quarterly basis. The technology roadmap for the Development Activities shall be based upon requirement inputs from Sanken and
shall be updated at least annually. The Team will describe the anticipated process technology required and review the progress of the Development Activities. The responsibilities of each Party’s development teams to accomplish the technology
roadmap activities, and the establishment, validation, and prioritization of items on the technology roadmap, will be agreed upon by the Team. 

3.    Staffing. In order to conduct the Development Activities, PSL will maintain an Advanced Discrete
Development Group and will evaluate and install new process modules. PSL will be responsible for and will have sole discretion regarding staffing and personnel assignments required to complete PSL’s portion of the Development Activities. Sanken
may assign staff to these projects as agreed to by the Team, and may station employees at PSL to work on the Development Activities. 

 4.    Expense of Development Activities. Sanken will bear
certain designated expenses for the Development Activities. On an annual basis, the Parties will mutually agree upon (a) the fee to be paid to PSL by Sanken for the ensuing fiscal year for these designated expenses (the “Annual Fee”);
(b) the timing of payment of the Annual Fee; and (c) any applicable assumptions concerning the designated expenses or other items that are included or excluded with the Annual Fee. PSL will bear responsibility for any expense that exceeds the
Annual Fee. 
 5.    Outside Party Involvement. The Parties may from time to time mutually decide to procure
assistance or technology from unrelated parties in connection with the Development Activities. Any contracts with such unrelated parties, or any arrangements between the Parties concerning payments to such parties, shall have such terms as the
Parties shall mutually agree and need not be attached as exhibits to this Agreement. Notwithstanding the foregoing, any Party may independently engage its own outside consultant concerning the Development Activities at its own expense. 

6.    Manufacturing for Sanken. PSL and Sanken, as applicable, will agree upon reasonable prices and terms for
products manufactured for Sanken by PSL using the Technology. The Parties anticipate that such pricing will incorporate the benefits of yield improvements and cost reductions. Sanken, as applicable, will provide good faith quarterly and long-range
forecasts of products to be purchased from PSL, and PSL will reserve and/ or install such capacity for Sanken. PSL will have a first right to produce wafers for Sanken that incorporate the technology (subject to Section 7). 

7.    Transfer of Technology. While the intention of the Parties is that PSL will manufacture products based
on the Technology, Sanken may, in the following limited situations, transfer an applicable portion of the Technology to an alternative manufacturing site: (a) a Party’s reasonably projected purchase requirements exceeds PSL’s capacity
and/or allocations to such Party; (b) material quality or delivery nonperformance with respect to products based on the Technology, provided that some reasonable early warning triggers of material nonperformance will be developed by the
Parties; (c) Sanken requires a second source for security of supply or dual sourcing due to business conditions and/or customer contractual requirements, provided that a substantial volume of production shall continue to be purchased from PSL
as negotiated with the applicable Party; or (d) transfer to a new owner of Sanken. 
 8.    Ownership of the
Technology. Sanken and PSL shall jointly own the Technology developed pursuant to this Agreement. Neither Sanken nor PSL shall sell, assign or transfer any of the Technology to any other party without the written consent of any other
Party or as expressly permitted under this Agreement. Sanken shall have the right of access to the details of the Technology.

(b)    The Development Activities shall be identified and agreed by the Team pursuant to such procedures as the Team may
develop from time to time. It shall not be necessary for the Development Activities to be set forth in a document signed by each Party. The Development Activities may be documented in such manner as the Team determines in its discretion. 

(c)    Prices and terms for products manufactured by PSL pursuant to Section 6 shall be determined by the applicable
Parties in any manner they deem appropriate, including without limitation formal agreements, purchase orders and acknowledgements, e-mail communication or such other documentation as may be reasonable and
customary for a supplier-customer relationship. 
 (d)    The documentation described in this Section 9 shall be
maintained in an orderly fashion with the business records of the Parties. However, it shall not be necessary, nor shall it be the practice of the Parties, to attach such documentation as exhibits to this Agreement. 

10.    Term. This Agreement shall continue in effect until such time as (a) the Parties mutually agree to
its termination; (b) the Parties adopt a successor agreement; or (c) the Parties fail to agree upon the Annual Fee for a fiscal year within three months after the commencement of such fiscal year. Sections 7, 8, and 9 herein shall survive
the termination of this Agreement. 
 11.    Confidentiality. Sanken shall not disclose any element of the
Technology to any third party, except for specifically identified Sanken customers in commercial situations for marketing and qualification purposes. Sanken will not apply for any patent in any country in connection with any Technology without
