IC TECHNOLOGY DEVELOPMENT AGREEMENT 

THIS IC TECHNOLOGY DEVELOPMENT AGREEMENT (“Agreement”) is entered into as of May 28, 2009 by and among Polar Semiconductor, Inc., a
Delaware corporation headquartered in Bloomington, Minnesota (“PSI”); Sanken Electric Co., Ltd., a Japanese corporation headquartered in Saitama, Japan (“Sanken”); and Allegro MicroSystems, Inc., a Delaware corporation
headquartered in Worcester, Massachusetts (“Allegro”). 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 with the anticipation that such technology may be used by
PSI to manufacture products for Sanken and Allegro; and 
 WHEREAS, the Parties wish to stipulate the terms and conditions that will apply to such
technology development; and 
 WHEREAS, the Parties have entered into several prior agreements concerning technology development, and wish to
integrate such agreements into a single agreement that will act as a successor to the prior agreements. 
 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 an IC 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 an IC 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 twelve (12) 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 Allegro and 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, PSI will
maintain an advanced technology group and will evaluate and install new process modules. PSI will be responsible for and will have sole discretion regarding staffing and personnel assignments required to complete PSI’s portion of the
Development Activities. Allegro and Sanken may assign staff to these projects as agreed to by the Team, and may station employees at PSI to work on the Development Activities. 

4.     Expense of Development Activities. Sanken and Allegro [XXX]. On an annual basis, the Parties will mutually agree upon
(a) the fee to be paid to PSI by Sanken and Allegro 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. PSI 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 or Allegro. PSI and Sanken or Allegro, as applicable, will agree upon reasonable prices and
terms for products manufactured for Sanken or Allegro by PSI using the Technology. The Parties anticipate that such pricing will incorporate the benefits of yield improvements and cost reductions. Sanken or Allegro, as applicable, will provide good
faith quarterly and long-range forecasts of products to be purchased from PSI, and PSI will reserve and/ or install such capacity for Sanken or Allegro. 

7.     Transfer of Technology. While the intention of the Parties is that PSI will manufacture products based on the
Technology, Sanken or Allegro 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 PSI’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 or Allegro 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 PSI as negotiated with the applicable Party; or (d) transfer to a new owner of Sanken or Allegro.

 8.     PSI Intellectual Property. Except as set forth in this
Section 8, PSI will retain ownership of all intellectual property that PSI owned prior to the Development Activities. The exception is that Sanken and Allegro shall have a nonexclusive license for the applicable portion of so-called Polar 35 technology, which is a technology upon which some of the Technology will be developed pursuant to the Development Agreement. PSI acknowledges receipt of $[XXX] from each of Sanken and Allegro as
compensation for such license. Such license shall continue for as long as Allegro and/ or Sanken use (either directly or by transfer permitted herein) any of the Technology developed pursuant to this Agreement. 

9.     Ownership of the Technology. Sanken, Allegro and PSI shall jointly own the Technology developed pursuant to this
Agreement subject to the following exceptions: (a) Allegro shall have sole ownership of all intellectual property related to the design and manufacture of magnetic sensors; and (b) Sanken and Allegro shall jointly own the SG5 technology
and its derivatives. Neither Sanken, Allegro, nor PSI shall sell, assign or transfer any of the Technology to any other party without the written consent of any other Party who has joint ownership in the Technology or as expressly permitted under
this Agreement. Sanken and Allegro shall have the right of access to the details of the Technology. Technology that is not subject to one of the exceptions set forth in subsection (a) or (b) above shall, unless otherwise agreed to in writing by
the Team, be jointly owned by all three Parties. 
 10.     PSI Use of SG5 Technology. With respect to that portion of the
Technology that is SG5 technology and its derivatives (which portion is jointly owned by Sanken and Allegro pursuant to Section 9), PSI may use individual unit processes within SG5 or its derivatives (such as devices, models, process design
kit, process control module, electrical test code for process control module, characterization reports, qualification reports, application notes, etc.) in the conduct of its business and manufacturing for others. Such elements of the Technology may
be ported by PSI across technology platforms in a modular way. However, PSI shall not use the Technology as a whole or use a combination of unit processes of the Technology so as to create a system or technology that competes with Sanken’s or
Allegro’s business or technology for five years after PSI establishes its capability to manufacture products for Sanken and Allegro using the Technology based upon successful qualification thereof.
