Statement of Work, SELLER shall notify BUYER within [***] if SELLER is unable or unwilling to supply such excess quantities to BUYER. If SELLER does not notify BUYER of any discrepancies on a
Purchase Order received by SELLER within [***] of receipt thereof; such Purchase Order(s) shall be deemed to have been accepted by SELLER. SELLER shall accept Purchase Orders that are issued by BUYER in accordance with BUYER’s forecasts and the
other terms and conditions of this Agreement. 
 3.5 SELLER shall deliver to BUYER only the quantity of Products authorized by BUYER’s

3.6 If any material used to make products is provided to SELLER by BUYER, BUYER must provide that material on the date required by SELLER. For
each day such material is delivered late by BUYER, the Delivery Date (as defined below) for the Products that are to incorporate such materials shall be extended by one day. 

3.7 In situations where either party provides materials or supplies to SELLER in connection with this Agreement and/or a Statement of Work
(s) (excluding Products purchased by BUYER hereunder), such receiving party shall use such materials and supplies only in accordance with the applicable Statement of Work for which it was received, and such receiving party shall not use it for
any other purpose. The receiving party shall be responsible for all such materials and supplies provided by the providing party while they are in the receiving party’s control or the control of its agents, and the receiving party shall
promptly, at the providing party’s direction, destroy or return to the providing party all unused quantities of materials and supplies provided by the providing party. If any materials or supplies provided by BUYER are destroyed or damaged by
SELLER as a result of SELLER’s negligence or intentional misconduct, then SELLER shall be responsible for replacing the destroyed or damaged materials or paying BUYER the replacement value of the damaged or destroyed materials and any costs or
expenses to accelerate the supply chain for such materials or supplies. For the avoidance of doubt, each party shall retain title to all materials and supplies while they are in the other party’s facility. 

4. EXCLUSIVITY 
 4.1 SELLER
agrees to manufacture and supply Exclusive Products (as defined below) exclusively to BUYER, as and when BUYER may order the same, pursuant to the terms and conditions of this Agreement and any applicable Statements of Work. During the Term and for
[***] thereafter, SELLER agrees not to manufacture or supply any Exclusive Product for itself, for any of its affiliates, or for any third party, or to manufacture, sell or supply any Exclusive Product to any third party without BUYER’s prior
written consent. For the purposes of this Section 4.1, “Exclusive Products” means superconducting magnets for synchrocyclotrons for proton therapy. Notwithstanding the foregoing, the exclusivity restrictions set forth in this
Section 4.1 shall terminate if BUYER: (a) fails to take delivery of the Minimum System Quantities (as defined below) [***], and such failure is not due to SELLER’s failure to perform its obligations hereunder; or (b) BUYER is in
material default of this Agreement and BUYER fails to cure such default within [***] of BUYER’s receipt of written notice of such default from SELLER. “Minimum System Quantities” means [***].

VERSION OF THIS EXHIBIT HAS BEEN FILED SEPARATELY WITH THE SECRETARY OF THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO AN APPLICATION REQUESTING CONFIDENTIAL TREATMENT UNDER RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

  

 4.2 During the term of this Agreement and subject to the provisions of Section 4.3
below, BUYER shall not outsource or secure from any other vendor the Exclusive Products. BUYER agrees that Seller shall be the exclusive supplier of the Exclusive Products aside from provisions below for partial supply by BUYER. 

4.3 Subject to BUYER having sufficient orders for Mevion S250 systems to support BUYER’s purchase of the Minimum System Quantities, BUYER
agrees to purchase the Minimum System Quantities from SELLER. In addition, during the Term and subject to the remainder of this Section 4.3, BUYER agrees to purchase Systems exclusively from SELLER, and not to manufacture Systems for sale nor
have Systems manufactured by a third party. Notwithstanding the foregoing, the exclusivity restrictions set forth in this Section 4.3 shall terminate if (a) SELLER fails to deliver any Product within [***] following the applicable Delivery
Date for such Product, (b) [***] or (c) SELLER is unable or unwilling to supply the Minimum System Quantities. In addition, the exclusivity restrictions set forth in this Section 4.3 shall not apply with respect to Systems in excess
of the Minimum System Quantities, if BUYER has forecasted such excess Systems and SELLER has notified BUYER of Seller’s inability or unwillingness to provide such excess Systems. For the avoidance of doubt, nothing herein shall restrict BUYER
from developing internal manufacturing capabilities for System so that BUYER is capable of manufacturing Systems in the event the exclusivity restrictions herein do not prohibit such manufacture. In the event that (a) BUYER has not been
relieved of its exclusivity obligations set forth in Section 4.3, and (b) BUYER delivers a MEVION S250 to a customer which includes a superconducting magnet system that was manufactured by BUYER (and not by SELLER), BUYER agrees to pay to
SELLER a fee of $[***] for each such delivered MEVION S250 (the “Magnet Manufacturing Fee”). The payment obligations set forth in this Section 4.4 shall terminate upon the earlier to occur of (i) the date that BUYER pays to
SELLER $[***] of aggregate Magnet Manufacturing Fees hereunder, (ii) the date that BUYER has purchased the Deposit Materials in accordance with Section 18, and (iii) expiration or termination of this Agreement. 

4.4 BUYER shall maintain accurate shipping records in sufficient detail to permit the identification of superconducting magnet systems
manufactured by BUYER for which a Magnet Manufacturing Fee is payable. Upon reasonable prior written notice to BUYER, an independent accountant selected by SELLER and reasonably acceptable to BUYER and not paid in whole or in part by a contingent
fee arrangement, shall have reasonable access during normal business hours, but not more often that once in any calendar year, to BUYER’s shipping records as may reasonably be necessary to conduct a review for the purpose of verifying the
accuracy of BUYER’s payment of Magnet Manufacturing Fees hereunder. Prior to commencing any such inspection, the accountant shall enter into a reasonable and customary confidentiality agreement with BUYER which prohibits the disclosure of any
information, except as provided in said confidentiality agreement, relating to BUYER to any person or entity, except that such accountant may issue a report to SELLER, the sole purpose of which shall be to report to SELLER whether BUYER complied
with the payment provisions of Section 4.5 above.

 5. PURCHASE PRICE 

5.1 Pricing 
 SELLER shall sell the Products to
BUYER at the purchase prices set forth on the applicable Statement of Work (as such prices may be adjusted hereunder, “Purchase Price(s)”). [***] Upon BUYER’s receipt of such proposal, the parties shall promptly discuss in good faith
an equitable adjustment to the Purchase Price. In the event the parties are unable to agree to such adjustment, the matter shall be addressed in accordance with the arbitration provision set forth in Section 22.5. The adjusted prices shall be
effective as set forth in Section 5.4. Purchase Prices shall be honored by SELLER for delivery to all BUYER sites or locations, and if authorized by BUYER, to any BUYER-authorized subcontractors or customers. 

5.2 All-Inclusive 
 The Purchase Price for each
Product shall be all-inclusive and represents the sole and exclusive consideration to SELLER hereunder for the Products or otherwise, except for [***]. BUYER shall not be billed for, nor shall BUYER have any obligation to pay, any charge or amount
not specifically authorized in BUYER’s duly issued Purchase Order. Any additional terms or conditions contained on any SELLER invoice, packing slip or other SELLER documentation shall not be binding on BUYER, and no action by BUYER (including
the payment of any such invoice in whole or in part) shall be construed as binding BUYER with respect thereto. 
 5.3 Taxes 

[***] 
 5.4 Effective Date of Purchase Price
Changes 
 All changes in Purchase Prices shall be effective only for new Purchase Orders for Products. 

5.5 Process Improvement 
 The parties shall
jointly manage process improvements for the manufacturing process for the Products. The parties shall conduct an annual review for material and labor cost reductions, lead time reduction, and inventory reduction, and SELLER shall keep a material and
labor cost breakdown containing all particulars that may be necessary for the purpose of performing such reviews. The parties shall make appropriate personnel available for such annual review, including operations management, procurement, and
planning resources for such party. Changes identified through the annual review process shall be handled as part of SELLER’s ECR (defined below) process and as further set forth in Section 3.

 5.6 Cost Reduction Allocation 

SELLER agrees to seek commercially reasonable ways to reduce the cost of manufacturing Products by methods such as reduction of materials costs and component
costs and improvements in procurement, production processes and labor efficiency (“Manufacturing Cost Reductions”). In the event that Manufacturing Cost Reductions are achieved by SELLER, including without limitation through Value
Engineering (V/E) efforts or through the process improvement review procedures set forth in Section 5.5, the then Purchase Price for the applicable Product shall, on a going-forward basis, be decreased by an amount equal to [***]. SELLER shall
promptly disclose all Manufacturing Cost Reductions to BUYER. 
 6. SYSTEM FORECASTS and CONFIRMED FIRM PURCHASE ORDERS 

6.1 As soon as practicable after the Effective Date and on or prior to the first business day of each calendar quarter thereafter, BUYER shall
provide SELLER with [***] rolling forecasts of BUYER’s anticipated requirements of Systems covering the [***] period commencing on the first business day of the calendar quarter following the day on which such forecast is provided by BUYER to
SELLER. 
 6.2 The first [***] of each forecast (the “Confirmed Firm Order Period”) shall be binding on BUYER. BUYER shall issue
Purchase Orders for each System within the [***] lead time for Systems. As part of the forecast and firm order detail issued quarterly, BUYER shall confirm the orders already specified for delivery during the Confirmed Firm Order Period, and
reconcile those firm orders in the second quarter of the Confirmed Firm Order Period to the previously forecast Systems. 
 6.3 In each
forecast following the initial forecast, BUYER may increase or decrease the aggregate quantity of Systems specified for delivery during the [***] of the forecast (The “Mid-Term Forecast Period”) from the amount set forth in corresponding
calendar period in the immediately preceding forecast by a net total of one System without incurring any penalty or additional liability hereunder. In the event that BUYER decreases the net quantity of Systems set forth in the Mid-Term Forecast
Period of a forecast by [***] Systems from the quantity forecasted for corresponding period in the immediately preceding forecast, BUYER agrees to pay to SELLER a rescheduling fee of [***] (the “Rescheduling Fee”) for [***]. In the event
that BUYER increases the aggregate quantity of Systems specified for delivery during the Mid-Term Forecast Period by [***] over the amount set forth for the corresponding calendar period in the immediately preceding forecast, SELLER shall use
commercially reasonable efforts to provide, but shall not be obligated to provide, such excess quantities of Systems. 
 6.4 The quantity of
Systems set forth in a forecast for the period following the Initial and Mid-Term Forecast Period [***] (the “Long Term Forecast Period”) shall be non-binding estimates only and BUYER shall have no obligation to purchase the quantity of
Systems forecast for the Long Term Forecast Period.

date that the SELLER has shipped such Product, BUYER may, free of charge and once per each such Product, reschedule the Delivery Date by delivering notice to Seller (delivered electronically, by facsimile, or by mail) to another date that is within
[***] following the original Delivery Date. Rescheduling the delivery of a Product to a date that is earlier than the Delivery Date set forth in the Purchase Order is subject to SELLER’s written consent. The new Delivery Date specified in
BUYER’s notice (or as agreed to by SELLER, if the proposed rescheduled date is earlier than the Delivery Date set forth in the Purchase Order) shall then become the new Delivery Date for the applicable Product, and the Purchase Order shall in
all other respects remain in full force and effect.

 10. SELLER SAFETY STOCK 

10.1 In the event that BUYER is capable of supplying SELLER with sufficient conductor material for SELLER to manufacture [***] (each, a
“Surplus System”), BUYER shall promptly notify SELLER of same. BUYER shall supply such conductor material to SELLER, and SELLER shall manufacture the Surplus Systems at SELLER’s expense in accordance with a schedule to be discussed
and agreed upon by the parties in good faith. Following completion of the manufacture of the first Surplus System, SELLER shall ship such Surplus System, at SELLER’s expense, along with a complete set of drawings, manufacturing documents and
other data and information that are at least sufficient to enable a reasonably skilled manufacturer in the trade to manufacture Systems [***] (including part drawings, bills of material, assembly, test, and inspection process travelers and data
collection forms) (the “System Manufacturing Information”), to the facility of SELLER’s wholly owned subsidiary, Everson Tesla Incorporated (“Everson Tesla”), located at Everson Tesla Incorporated, 615 Daniels Road,
Nazareth, PA 18064. SELLER shall be solely responsible for storage costs and risk of damage and loss of the Surplus System while in transit to and stored at Everson Tesla’s facility. The second System manufactured pursuant to this
Section 10 shall be stored in a suitable container at SELLER’s manufacturing facility located at Unit 1, Water Lane, Storrington, RH20 3EA, United Kingdom. Nothing in this section shall preclude Tesla and Mevion from mutually agreeing to
supply conductor and produce cold masses or systems in addition to the two safety stock in order to maximize efficiency of the production process. 

10.2 Production of Surplus Systems is of secondary importance to production demands, and shall be done without impacting the System production
and/or delivery schedule. Notwithstanding the foregoing, the Surplus Systems will be utilized by BUYER on a first in, first out basis as follows. Provided there is a Surplus System at the Everson Tesla Facility in Nazareth, PA, the BUYER shall take
delivery of a regularly forecasted system from that location. SELLER shall replace that system with a system already in stock at SELLER’s facility in StorrmgtoiLUK. SELLER shall then replace the Surplus System at the Storrington location in no
more than [***] to provide for the balance of [***] Surplus Systems to continue. SELLER shall organize production and BUYER shall supply sufficient conductor to enable the first surplus system to be available in Nazareth, PA within one year of
signing this agreement. 
 10.3 Notwithstanding the foregoing, SELLER’s obligations with respect to maintenance of Surplus Systems
shall terminate as set forth in Section 17. 
 11. MODIFICATION OF PRODUCTS 

11.1 BUYER shall have ultimate affirmative and negative control of design changes. SELLER shall implement any design change requested by BUYER
within ninety (90) days, with the SELLER having opportunity to re-quote if there is a change in the Product’s manufacturing cost. Any design change proposed by SELLER for Products supplied hereunder shall be sent to BUYER for prior review
and approval before implementation. The parties agree to jointly review any proposed design change within [***] after receipt of such proposal. Changes shall be communicated using SELLER’s Engineering Change Request (ECR) process which is
attached

hereto as Attachment V. In the event that either SELLER or BUYER requests a design change to a Product and SELLER reasonably determines that, as a result of such design change, an adjustment is
required to the proposed delivery schedule set forth in a Purchase Order or Statement of Work, as applicable, the parties shall discuss in good faith, agree on such adjustment and modify the Purchase Order or Statement of Work, as applicable,
accordingly. 
 11.2 SELLER shall not change material, components, manufacturing process, dimensions, tolerances, or specifications for the
Products without prior written consent of BUYER, which consent shall not be unreasonably withheld. In all cases, SELLER shall provide BUYER with at least [***] written notice (or such longer period as agreed to by the parties) in advance of
SELLER’s proposed implementation of any modification, and shall continue to manufacture unmodified Products until such time as BUYER approves of the proposed change. BUYER retains sole discretion to accept or reject proposed design changes. For
the purposes of this Agreement, a Product shall be “compatible” if it shall continue to perform all significant functions of the Product before such modification when used in conjunction with Existing Systems, without any modification to
such Existing Systems. SELLER shall assure that all Products that are modified after the Effective Date (“Modified Product(s)”) shall be “compatible” (as defined herein) in such modified form with all hardware and software
utilized by BUYER in conjunction with such Modified Products (including monitoring software) prior to the modification thereof (collectively, “Existing Systems”). 

11.3 Notwithstanding Section 11.2, if a supplier of SELLER is no longer able or willing to supply to SELLER materials or components as
the case may be, SELLER shall notify BUYER of the same and SELLER shall be permitted to secure a different supplier with the consent of the BUYER, which consent shall not be unreasonably withheld. 

12. QUALITY INSPECTION AND ACCEPTANCE OF INCOMING PRODUCT 

12.1 Shipping Condition 
 SELLER shall ship all
Products to BUYER in new condition. SELLER shall fill each Purchase Order in accordance with its terms and the provisions hereof, except as otherwise expressly provided herein 

12.2 Inspection; Acceptance 

(a) Before shipping any Product, SELLER shall test the Product in accordance with testing and quality assurance procedures to
be mutually agreed to by the parties in writing (the “Testing Procedures”) to ensure that such Product is free from defects and conforms to the applicable Specifications. Any Product that is not free from defects or does not conform to the
applicable Specifications is referred to herein as a “Defective Product.” SELLER shall notify BUYER [***] of performing any Testing Procedures so that a BUYER representative has the opportunity to be present at SELLER’s facility to
observe such Testing Procedures. At or before shipment of any Product, SELLER shall furnish the BUYER with a certificate, in form and substance

reasonably satisfactory to the BUYER, to the effect that SELLER has performed the Testing Procedures on such Product and did not identify any defects or nonconformities to the Specifications
(“Initial Acceptance”). If the Testing Procedures establish that the Product is a Defective Product, BUYER may (i) elect to take delivery of the Product and equitably reduce the Purchase Price by a mutually agreed upon amount [***];
or (ii) require SELLER to promptly replace or correct the Defective Product. SELLER shall document a corrective action for all rejected Defective Products. For any Defective Products that are manufactured using BUYER provided materials or
supplies, SELLER is responsible for reimbursement of BUYER, or recovering the BUYER materials or supplies in a method to be approved by BUYER. BUYER agrees that there will be no hold-back from any future payments for a Product regarding a prior
Defective Product. 
 (b) Upon receipt of a Product, BUYER shall have a period of up to [***] from shipment to test (through
installation, inspection, or use thereof) the Product to confirm that such Product, as delivered, is free from defects and conforms to the applicable Specifications. BUYER shall notify SELLER as soon as practicable whether or not such Product is
free from defects and conforms to the applicable Specifications. If BUYER tests the Product during such [***] period, “Final Acceptance” shall be deemed to occur when (i) BUYER’s delivery of notice to SELLER confirming that the
PRODUCT complies with the Specifications, (ii) or, if BUYER reasonably determines that the Product does not conform to the Specifications, the date that such non-conformity is remedied pursuant to Section 13.2. If, however, BUYER does not
test the PRODUCT during such [***] period, or does not notify SELLER that such PRODUCT does or does not conform to the Specifications during such [***] period, “Final Acceptance” shall be deemed to have occurred upon the expiration of such
[***] period. For the avoidance of doubt, no testing, inspection or other action by the BUYER shall in any way derogate from SELLER’s warranties or BUYER’s remedies set forth herein with respect to such Product. 

(c) BUYER and SELLER shall mutually agree to a detailed Device Master Record (DMR) and documentation for each Product,
including, without limitation, a series of in-process tests for each Product, and hold points in manufacturing of the Product to allow for BUYER review and approval of in-process test results. BUYER shall be permitted to view in-process tests, but
shall be strictly prohibited from copying or removing any information except as required by law or regulation, and after notice to SELLER with the opportunity of SELLER to ascertain if such law or regulation requires the copying or removing of such
information. For purposes of this Agreement, “DMR” shall mean (i) manufacturing process development for Product; (ii) all manufacturing and control procedures necessary for the manufacturing, testing and quality control release
of Product; and (iii) sourcing and testing of all raw materials and components used in the production of any Product. As reasonably required by BUYER in connection with Product manufacturing activities hereunder, SELLER shall enter into a
written quality agreement with BUYER.

13.3 Conditions 
 This Product warranty is
subject to BUYER promptly notifying SELLER in writing of the failure as it appears to BUYER, making available within a reasonable interval a written report of the defect or failure including description of the circumstances where under the defect or
failure appeared, (to the extent BUYER is capable of providing such information) and access to the Product. 
 13.4 Limitations 

THE FOREGOING WARRANTIES AND THOSE IN THIS SECTION 13 ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THOSE OF MERCHANTABILITY OR FITNESS

malfunctioning or damage is caused by non observance of any of the provisions under a-e, and would otherwise not have occurred. In the event that SELLER repairs a product which is not covered by warranty due to operation of this Section 13.4,
SELLER may at its discretion, offer a warranty on the product so repaired.

 13.5 Epidemic Faults 

Under this warranty SELLER warrants to BUYER that Product and Spare Parts shall be free of epidemic faults (class failures). Epidemic faults are for the
purpose of this Agreement defined as defects which are the same or have the same origin with a class failure quantity of [***] Products within a maximum period of [***] from the delivery date of the last of the [***] Products. [***] In case of such
epidemic faults, SELLER, after the initial warranty period in accordance with Section 13.2, warrants solely that the Products or relevant Parts not yet delivered shall be upgraded, and for all Products and Parts already delivered upgraded
components or Products and Parts shall be available from SELLER free of charge and BUYER shall be responsible for the building in and building out of said components, as far as reasonably may be expected. In case said faults compromise the
certification of the Product to safety standards in effect at the time the Product was delivered or in case said faults endanger persons, SELLER shall bear the costs for the building in and building out of said components as well. Notwithstanding
the above, SELLER shall not be responsible for any Epidemic Faults caused by any parts or material supplied by BUYER. 
 13.6 Fit for
Purpose 
 SELLER warrants that the Products and Spare Parts shall be free from defects in design, material and workmanship, shall meet all Specifications,

Escrow Agent, and SELLER agrees to facilitate such delivery promptly following the occurrence of such Release Condition. Without overriding or modifying BUYER’s existing rights to all designs and manufacturing knowhow related to the System,

 19. FORCE MAJEURE 

Neither SELLER nor BUYER shall be considered in default or liable for failure to perform any provision of the Agreement if such delay or failure arises
directly or indirectly out of an act of nature, acts of the public enemy, unusually severe weather conditions, insurrection, riot, government actions (including delays caused by customs agencies other than for fault of SELLER) and other such causes
beyond the control of SELLER or BUYER, provided the affected party notifies the other party within [***] of occurrence. In the event the Force Majeure delay continues for a period of [***] or more, the other party may terminate this Agreement with
no further liability to the other party. 
 20. CONFIDENTIALITY; OWNERSHIP OF INTELLECTUAL PROPERTY 

20.1 The parties acknowledge and agree that all information or data disclosed by one party to the other shall be subject to the terms and
conditions of the Mutual Confidentiality Agreement attached hereto as Attachment VII. 
 20.2 Nothing in this Agreement shall affect the
ownership by either party of (a) any Intellectual Property or process owned by or in the possession of that party or its licensors at the date of this Agreement or (b) Intellectual Property developed independently of the work undertaken
under this Agreement by or on behalf of such party or its licensors without reference to any of the Confidential Information disclosed by the other party (“Independent Intellectual Property”). Other than giving SELLER the right to
manufacture the Products for BUYER, nothing in this Agreement shall give either Party the right to use the other Party’s Independent Intellectual Property. For purposes of this Agreement, “Intellectual Property” shall mean all
patents, patent applications, all provisional, divisional, continuations, renewals, continuations-in-part, re-examinations, patents of addition, supplementary protection certificates, extensions, letters of patent, registration or confirmation
patents and reissues with respect to any patents described in the foregoing clauses, any know-how, data, technology, copyrights, industrial property and technical information. 

20.3 It is agreed by the parties that (a) SELLER owns and shall own all Intellectual Property relating to the design and operation of
processing equipment and process implementation know how involved in their production of the [***] (“Jointly Owned Intellectual Property”). 

20.4 It is possible that, personnel of SELLER and BUYER will, independently or jointly, conceive of inventions or discoveries, relating to the
production, construction, or use of Jointly Owned Intellectual Property, or some aspect thereof. Except for improvements to SELLER’s or BUYER’S Intellectual Property, all such inventions concerning Jointly Owned Intellectual Property shall
be considered to be Jointly Owned Intellectual Property. In this respect, unless the Parties mutually agree to alternative responsibilities, decisions concerning applications for patent protection of any or all of these inventions shall be the
shared responsibility of SELLER and BUYER, who will provide notice to the other party of the invention and jointly file and prosecute such applications and maintain any resulting patents.

The Parties agree that each Party will promptly notify the other Party of when an invention concerning Jointly Owned Intellectual Property has been conceived. This discussion shall take place no
less frequently than once per quarter. When Jointly Owned Intellectual Property is developed during the Term of this Agreement, the Parties agree that, at any time they are free to engage in good faith discussion regarding the possibility that one
Party wishes to become sole owner of such property, and what consideration may be appropriate for such a change in ownership. 
 20.5 In the
event of the occurrence a Release Condition and receipt of the required payment to SELLER by BUYER, SELLER hereby grants to BUYER an irrevocable, perpetual, royalty-free, non-transferrable (except in accordance with Section 15), worldwide
license under Intellectual Property owned or controlled by SELLER solely to the extent necessary to manufacture or have manufactured Products for use in BUYER’s products, and for no other purpose. For the avoidance of doubt, the foregoing
license grant does not provide BUYER with any rights under SELLER’s Intellectual Property to manufacture any products other than Products, and does not permit BUYER to sublicense or otherwise transfer any such rights to any third party (other
than a third party that is manufacturing Products on a contract manufacture basis as BUYER’s agent for sale to BUYER.) The foregoing license does not provide BUYER with any rights to enforce any of SELLER’s Intellectual Property against
any third party or to prosecute or otherwise control SELLER’s maintenance of its Intellectual Property. 
 20.6 BUYER shall not be
restricted from note taking as long as the resulting records are maintained in accordance with the confidentiality provisions included in this Agreement. BUYER may have any picture taken of BUYER’s products in process by SELLER and provided to
BUYER in accordance with SELLER’s policy on use of cameras. 
 21. COMMUNICATION BETWEEN PARTIES 

All notices of default or termination required or permitted to be given under this Agreement shall be made in writing and shall be deemed to have been given
when personally delivered or when deposited for mailing by first class registered or certified mail, return receipt request, with proper postage prepaid and addressed as follows:

any agreement, understanding, representation, warranty, or covenant not expressly set forth in writing herein. This Agreement may be amended only by a written instrument duly executed by both parties, and may not be amended orally or course of

other. 
 22.4 Waivers 
 All waivers hereunder
must be made in writing by a duly authorized representative of the party against whom the waiver is to operate, and failure at any time to require the other party’s performance of any obligation under this Agreement shall not affect the right
subsequently to require performance of that obligation. Each party’s rights and remedies hereunder shall be cumulative with, and may be exercised without prejudice to, such party’s other rights and remedies under this Agreement, at law, or
in equity. 
 22.5 Dispute Resolution

 1. Definition of Confidential Information. “Confidential Information” as used in this Agreement shall
mean any and all technical and non-technical information including, without limitation, patent, copyright, trade secret and proprietary information, techniques, sketches, drawings, models, inventions, know-how, processes, formulae, apparatus,
equipment and biological materials related to the current, future and proposed products and services of each of the parties, and includes, without limitation, their respective information concerning research, experimental work, development, design
details and specifications, engineering, financial information, procurement requirements, purchasing, manufacturing, customer lists, business forecasts and sales and marketing plans “Confidential Information” also includes
proprietary or confidential information of any third party who may disclose such information to either party in the course of the other party’s business. Such information disclosed by the disclosing party (“Discloser”) will be
considered Confidential Information by the receiving party (“Recipient”), only if such information is conspicuously designated as “Confidential”, or if provided orally, identified as confidential at the time of disclosure
and confirmed in writing within thirty (30) days of disclosure. 
 2. Nondisclosure and Nonuse Obligation. Each of the parties
agrees that it will not make use of, disseminate, or in any way disclose any Confidential Information of the other party to any person, firm or business, except to the extent necessary for negotiations, discussions, and consultations with personnel
or authorized representatives of the other party, and any purpose the other party may hereafter authorize in writing. Furthermore, the existence of any business negotiations, discussions, consultations or agreements in progress between the parties
shall not be released to any form of public media without written approval of both parties. Each of the parties agrees that it shall treat all Confidential Information of the other party with the same degree of care as it accords to its own
Confidential Information, and each of the parties represents that it exercises reasonable care to protect its own Confidential Information. If either party is not an individual, such party agrees that it shall disclose Confidential Information of
the other party only to those of its employees who need to know such information and certifies that such employees have previously agreed, either as a condition to employment or in order to obtain the Confidential Information, to be bound by terms
and conditions substantially similar to those of this Agreement. Recipient will immediately give notice to Discloser of any unauthorized use or disclosure of the Confidential Information. Recipient agrees to assist Discloser in remedying any such
unauthorized use or disclosure of the Confidential Information. Except as required by law, neither party shall use the name of the other party or reveal the existence or substance of ongoing discussions, negotiations, or evaluations related to the
subject matter of this Agreement, or any subsequently executed agreement, to any third party without the prior written consent of the other party, which consent shall not be unreasonably withheld.

 3. Exclusions from Nondisclosure and Nonuse Obligations. Each party’s obligations
under Paragraph 2 (“Nondisclosure and Nonuse Obligations”) with respect to any portion of the other party’s Confidential Information shall terminate when the party seeking to avoid its obligation under such Paragraph can
document that: (i) it was in the public domain at or subsequent to the time it was communicated to Recipient by Discloser through no fault of Recipient; (ii) it was rightfully in Recipient’s possession free of any obligation of
confidence at or subsequent to the time it was communicated to Recipient by Discloser; (iii) it was developed by employees or agents of Recipient independently of and without reference to any information communicated to Recipient by Discloser;
(iv) it was communicated by the Discloser to an unaffiliated third party free of any obligation of confidence; or (v) the communication was in response to a valid order by a court or other governmental body, was otherwise required by law,

of such party, shall remain the property of such party and shall be returned to it promptly at its request, together with any copies thereof. 

5. Independent Development. Discloser understands that Recipient may currently or in the future be developing information internally,
or receiving information from other parties that may be similar to Discloser’s information. Accordingly, nothing in this Agreement will be construed as a representation or inference that Recipient will not develop products, or have products
developed for it, that, without violation of this Agreement, compete with the products or systems contemplated by Discloser’s Confidential Information. 

6. Disclosure of Third Party Information. Neither party shall communicate any information to the other in violation of the proprietary
rights of any third party. 
 7. No Warranty. All Confidential Information is provided “AS IS” and without any warranty,
express, implied or otherwise, regarding its accuracy or performance. 
 8. No Export. Neither party shall export, directly or

legality, validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby.

to the non-breaching party for which there will be no adequate remedy at law, and the non-breaching party shall be entitled to injunctive relief and/or a decree for specific performance, and such other relief as may be proper (including monetary
