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 [***].

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.

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.

6.5 Rescheduling Purchase Orders

Within [***] of the scheduled delivery date for a Product as set forth in the BUYER’s Purchase Order (the “Delivery Date”), but prior to the 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.

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, ▇▇▇▇▇▇▇ Tesla Incorporated (“▇▇▇▇▇▇▇ Tesla”), located at ▇▇▇▇▇▇▇ Tesla Incorporated, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇. 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 ▇▇▇▇▇▇▇ 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 ▇▇▇▇ ▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇. 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 ▇▇▇▇▇▇▇ 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.

12.1 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.

(d) BUYER and its agents and designees shall have the right to audit SELLER’s facilities, systems, records, procedures, and documentation related to this Agreement and any Statement of Work. In connection with any such audit, SELLER shall also provide BUYER reasonable access to its personnel. Such audits may be conducted upon reasonable notice during the Term and for a period of up to [***] after termination or expiration of this Agreement, or for such longer period as may otherwise be required under applicable laws. If requested by BUYER, and provided that the exclusivity described in Section 4.1 is still applicable, SELLER shall permit and provide working space for BUYER to staff persons on location at SELLER’s premises during preparation for manufacturing and packaging. Such persons shall be given reasonable access to all records, facilities and personnel working on any Statement of Works, including, without limitation all quality and manufacturing process documentation including part specifications, part drawings, assembly drawings, bills of material, assembly instructions (travelers), test procedures, test fixtures, and training records. BUYER’S rights hereunder are specifically limited to the right to audit and shall not include any right to copy or remove information except as required by law or regulation. BUYER’S personnel will only be given access to records and other data in the presence of SELLER’s personnel. BUYER shall not be restricted from note taking as long as the resulting records are maintained in accordance with the confidentiality provisions included below.

12.3 Quality Assurance

SELLER shall establish process controls, ongoing inspection and test procedures such that the Products manufactured meet the required quality level agreed upon by BUYER and SELLER.

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.

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.

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.

4. Ownership of Confidential Information and Other Materials. All Confidential Information, and any Derivatives thereof whether created by Discloser or Recipient, remain the property of Discloser and no license or other rights to Confidential Information is granted or implied hereby. For purposes of this Agreement, “Derivatives” shall mean: (i) for copyrightable or copyrighted material, any translation, abridgement, revision or other form in which an existing work may be recast, transformed or adapted; (ii) for patentable or patented material, any improvement thereon; and (iii) for material which is protected by trade secret, any new material derived from such existing trade secret material, including new material which may be protected by copyright, patent and/or trade secret. All materials (including without limitation, documents, drawings, models, apparatus, sketches, designs and lists) furnished to one party by the other, and which are designated in writing to be the property 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 indirectly, any technical data acquired from the other pursuant to this Agreement or any product utilizing any such data to any country for which the U.S. Government or any agency thereof at the time of export requires an export license or other government approval without first obtaining such license or approval.

9. Term. This Agreement shall govern all communications between the parties that are made during the period from the effective date of this Agreement to the date on which either party receives from the other written notice that subsequent communications shall not be so governed; provided, however, that each party’s Nondisclosure and Nonuse Obligations with respect to Confidential Information of the other party which it has previously received shall continue in perpetuity unless terminated pursuant to Paragraph 3 (“Exclusions from Nondisclosure and Nonuse Obligations”).

Any notice required or permitted by this Agreement shall be in writing and shall be delivered as follows with notice deemed given as indicated: (i) by personal delivery when delivered personally; (ii) by overnight courier upon written verification of receipt; (iii) by telecopy or facsimile transmission upon acknowledgment of receipt of electronic transmission; or (iv) by certified or registered mail, return receipt requested, upon verification of receipt.

12. Severability. Should any provisions of this Agreement be held by a court of law to be illegal, invalid or unenforceable, the legality, validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby.

13. Waiver. The waiver by Discloser of a breach of any provision of this Agreement by Recipient shall not operate or be construed as a waiver of any other or subsequent breach by Recipient.

14. Injunctive Relief. A breach of any of the promises or agreements contained herein will result in irreparable and continuing damage 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 damages if appropriate).

15. Entire Agreement. This Agreement constitutes the entire agreement with respect to the Confidential Information disclosed herein and supersedes all prior or contemporaneous oral or written agreements concerning such Confidential Information.
