4. First Article Procedures.

4.1. Prototype. [***], Supplier will build, assemble, test and deliver to Eargo an initial prototype of the Product in accordance with the then-current applicable Specifications, SOW, and BOM (each a “Prototype”). Supplier will demonstrate to Eargo that the Prototype is in Compliance, which if requested will include testing the Prototype in accordance with the procedures set out in Section 4.3 below. Eargo does not guarantee that Supplier’s manufacture of a Prototype will result in the manufacturing of a First Article, or in Orders for any Products. Eargo reserves the right to engage other manufacturers to build and manufacture Products based on the Prototype. For the avoidance of doubt, Supplier will not manufacture any Products based on any Prototype, unless such Prototype has also been designated as an Approved First Article by Eargo in accordance with the procedures set out in the following provisions of this Section 4.

8

4.2. First Article. Supplier will build, assemble, test and deliver to Eargo a single Unit of the Product (“First Article”) in accordance with the then-current applicable Specifications, SOW, BOM, and, if applicable, the Prototype for that particular Product, it being understood by Supplier that the First Article may not be adequate; accordingly, Supplier will create as many First Articles, at Supplier’s sole cost and expense, as are necessary to satisfy the procedure described in this Section 4 (each a “First Article”). Supplier is responsible for correcting, at its sole cost and expense, any deficiencies in any First Article discoverable by Supplier prior to delivery of the same to Eargo. Supplier will deliver each First Article to Eargo for its inspection and testing. Supplier understands and agrees, however, that Eargo is not solely responsible for testing the First Article but may elect to do so as to certain matters.

4.3. First Article Testing. For each First Article, Supplier will perform the following testing in accordance with the requirements and sequence described below in this Section 4.3, at Supplier’s sole cost and expense. Supplier will perform all testing promptly and complete such testing as set forth in the applicable SOW. For each First Article, Supplier will inspect and test the First Article to determine if such First Article meets the then-current Specifications and BOM for that proposed Product as to each and every applicable test subject described below, is in Compliance in all other respects, and is otherwise suitable for Eargo’s business purposes as described in this Agreement and the applicable SOW, including as captured in any ECOs. A First Article will not be considered or eligible for consideration as an Approved First Article unless all testing outlined below is completed and successful results are achieved. Supplier will deliver the results of each and all testing to Eargo. Eargo reserves the right to independently conduct any tests or to validate Supplier’s reported test results in any instance against Eargo’s own findings or that of a third party testing provider engaged by Eargo. Eargo reserves the right to require Supplier to re-perform any tests for the First Article and Supplier will comply and re-perform such tests at Supplier’s sole cost and expense. Supplier agrees to and will promptly provide to Eargo, at Supplier’s sole cost and expense, all results of such testing and re-testing.

4.3.1. Form Testing. Following Eargo’s receipt of the First Article, Supplier will inspect and test the First Article to determine if such First Article meets the then-current Specifications and BOM for that proposed Product as to form, is in Compliance in all other respects, and is otherwise suitable for Eargo’s business purposes.

4.3.2. Fit Testing. Following successful completion of the form testing, Supplier and Eargo will inspect and test the First Article to determine if such First Article meets the then-current Specifications and BOM for that proposed Product as to fit relative to the Product and the applicable system requirements, is in Compliance in all other respects, and is otherwise suitable for Eargo’s business purposes.

4.3.3. Function Testing. Following successful completion of the form and fit testing, Supplier will inspect and test the First Article and, in particular, its Components, to determine if such First Article meets the then-current Specifications and BOM for that proposed Product as to function including Component testing, is in Compliance in all other respects, and is otherwise suitable for Eargo’s business purposes.

9

4.4. Approved First Article. After (a) all of the foregoing tests are completed in accordance with the above for each First Article, (b) the final First Article is confirmed to comply with the then-current applicable Specifications and BOM for the proposed Product, is in Compliance in all other respects, and is otherwise suitable for Eargo’s business purposes, and (c) Eargo has received the results of such testing from Supplier and Eargo has evaluated, validated and considered the findings from all such testing, then Eargo will issue its formal approval or rejection of the applicable final First Article. Eargo’s silence will not be deemed approval of a First Article. In addition, any approval or apparent approval issued by Eargo casually or after one test is completed will not be construed as approval of a First Article for purposes of this Section 4.4 if all other testing was not complete. Additionally, Eargo’s acknowledgment that a test of a First Article has been completed will not be construed as an approval. If and only if Eargo notifies Supplier, in writing, of Eargo’s acceptance of the final First Article and satisfaction with the test results, after all of the foregoing tests have been successfully completed, will the final First Article be deemed the Eargo-approved First Article of the applicable Product (the “Approved First Article”).

4.5. Rejection/Re-performance. If Eargo determines, in its sole discretion, that the applicable First Article is unacceptable or if any particular test fails or produces results that are unacceptable to Eargo then Supplier will be required to re-perform the applicable test(s) or all tests, as the case may be, at Supplier’s sole cost and expense. Unless otherwise agreed by the parties in writing, Supplier will either deliver to Eargo a corrected First Article, or re-perform any or all tests within [***] of Eargo’s notice of rejection. Eargo may elect to describe why the First Article failed to meet Compliance and/or issue an ECO, update the Specifications, or make other changes pursuant to Section 5 below, in which case Supplier will create and deliver another First Article for re-testing and acceptance in accordance with Section 4.3 above.

4.6. Use of Approved First Article. Supplier (and the Approved Vendors) will not manufacture any Products based upon a First Article that is not officially approved by Eargo as an Approved First Article and Eargo, its Affiliate(s), and Approved Buyer(s) will not have any obligation to pay Supplier for any Products manufactured on that basis. Supplier understands that a First Article does not alone qualify as an Approved First Article or an authorization to manufacture the applicable Product, even if a Purchase Order has been issued to Supplier on or about the time at which a First Article is delivered. Once the Approved First Article is confirmed, Supplier will not make any changes to (a) the Approved First Article, including but not limited to the applicable branding and/or packaging, (b) its Manufacturing Process for the same, (c) or any other process or methodology pertaining to that Approved First Article [***], or (d) its Subcontractors. Any above change to or in connection with an Approved First Article that is not specifically approved in advance and in writing, in each instance, by Eargo, is prohibited and will be at Supplier’s sole risk, cost and expense. Supplier agrees to inform Eargo of any potential change in its Manufacturing Process related to Products or that of an approved Subcontractor no less than [***] prior to the date the Supplier or such Subcontractor is contemplating the implementation of the change. If any changes are made to the [***], Eargo may require that Supplier create a new First Article for Eargo’s review and acceptance, in which case Supplier will cease manufacturing any Products until such time that a new First Article is created, tested and approved to result in an Approved First Article pursuant to and in accordance with this Section 4.

5.4. Acceptance of ECO. Notwithstanding anything in this Section or anywhere else in this Agreement, Supplier acknowledges and agrees that it will (a) promptly execute any Approved ECO: (i) which does not result in any additional costs in, or changes in the timing of, the performance of such Services or production, testing, manufacture or delivery of Products, or (ii) which results in additional costs in, and/or changes in the timing of, the performance of such Services, but where Eargo has agreed to pay the reasonable costs of the Changes and/or agreed to the reasonable adjustments to the timing for such Changes, and (b) promptly implement any and all Changes specified in any such Approved ECO in compliance with the terms of such Approved ECO and this Agreement.

5.5. Exceptions to ECO Process. Notwithstanding anything to the contrary, the exceptions to the ECO process are (a) Eargo’s updates to: (i) the list of Approved Buyer(s), (ii) the list of Approved Vendors, (iii) the Policies, and (iv) other Exhibits to this Agreement that do not pertain to any particular SOW, Specifications, BOM or similar matters, and (b) any amendments to this Agreement mutually executed by the parties. In the event of any of the foregoing, Supplier acknowledges that no ECO is required or will be submitted and that such changes are effective immediately upon the date of such notice by Eargo to Supplier.

6. Manufacturing.

6.1. Manufacturing Process. Supplier will manufacture all Units in accordance with the Manufacturing Process, including, without limitation, the BOM, and, any instructions, drawings and other records provided by Eargo, that must be used to produce a Unit (the “Device Master Record” or “DMR”). Without limiting the foregoing, Supplier will also comply with the quality specifications set forth in Supplier’s Quality Manual, which will be provided to Eargo upon request. Supplier is not permitted to and will not make or implement any changes to the Manufacturing Process unless each proposed change is made in accordance with the ECO procedure in this Agreement and under a resulting Approved ECO prior to implementation of the proposed change.

6.2. Forecasts. Eargo will provide non-binding [***] rolling forecasts to Supplier, identifying Eargo’s potential future Product needs for the applicable period (“Forecasts”). Forecasts are for planning purposes only, and are not an order, purchase or commitment. Supplier will accept each Forecast within [***] of receipt of the same. Supplier will allocate enough manufacturing capacity, Components and raw materials for the Products, to be able to meet each Forecast. If there is a capacity constraint, Supplier will give Eargo priority allocation. For avoidance of doubt, Eargo will not be liable for any increased capacity or other actions that Supplier may take or not take as a result of such Forecast. Eargo makes no guarantee that any Forecast is accurate.

6.3. Minimum Inventory Levels. Continuously throughout the Term, unless otherwise indicated by Eargo, Supplier agrees to and will maintain a minimum [***] inventory quantity (i.e., calculated and based upon Eargo’s most recent Forecast) of the Products that are readily available for shipment (“Minimum Inventory”). All Products manufactured and/or Components procured by Supplier to meet a then-current Minimum Inventory quantity will be considered “Inventory” under this Agreement. Supplier understands and agrees, however, that in no event will Eargo be responsible for any costs associated with Supplier’s compliance with the Minimum Inventory

12

requirement or for the insurance, storage or other costs associated with any Inventory. When Supplier is creating Inventory levels to satisfy the required Minimum Inventory, any reduction in quantity of Products that were ordered pursuant to a Purchase Order, or any quantity of Products ordered pursuant to a Purchase Order that is later cancelled by Eargo, will be [***]. Supplier will monitor and report its Inventory to Eargo on a [***] basis or at other time intervals as mutually agreed upon in writing by both parties. Supplier will maintain insurance on all Inventory and will ensure that the Inventory is kept in a secure location. Eargo will have the right to inspect any and all locations where Inventory is stored, upon request.

6.4. Spare Parts. From time to time, Eargo, its Affiliate(s), and/or the Approved Buyer(s) may purchase any or all of the Components for the Products from Supplier by issuing an Order. All Components will be sold to Eargo at the price set forth in the applicable Order not to exceed Supplier’s actual cost, [***] and will be subject to the terms of this Agreement.

6.5. Excess and Obsolete Inventory. “Excess Inventory” means unique and custom materials that Supplier owns or has an irrevocable commitment to purchase, which cannot be re-used by Supplier’s other customers or sold on the secondary market and which are limited to quantities that will not be consumed in the [***] following Eargo’s then-current Forecast projections. “Obsolete Inventory” means unique and custom materials that Supplier owns or has an irrevocable commitment to purchase, which cannot be re-used by Supplier’s other customers or sold on the secondary market and which are limited to quantities that will not be consumed in the [***] following Eargo’s then-current Forecast projections. Supplier will inform Eargo of the financial impact of Obsolete Inventory within [***] of material obsolescence (e.g., from ECO release that deems or renders the material obsolete). Eargo will in no way be responsible for Obsolete Inventory that [***] of material obsolescence. Supplier may submit a claim for reimbursement of its storage costs for such Excess Inventory or Obsolete Inventory to Eargo within [***] from the end of such applicable period. Supplier’s failure to submit such a claim within this [***] period will constitute waiver of any claim for reimbursement for storage costs associated with the Excess Inventory or Obsolete Inventory. Any potential storage costs must be mutually agreed to by the parties in writing.

6.6. Contingency Plan. Supplier is responsible for anticipating and promptly notifying Eargo of any inability on its part or its Subcontractors’ part to perform their respective obligations under this Agreement. Supplier will maintain continuously throughout the Term a contingency plan, which may be reviewed and approved by Eargo at its sole discretion, and includes emergency back-up capacity, alternative or back-up Subcontractors and Approved Vendors, back-up or redundant systems or Manufacturing Process, and appropriate Records (as defined below) protection and recovery, to allow Supplier to continue to perform the Services, maintain the Minimum Inventory, issue Reports, and test, manufacture and deliver the Units in accordance with this Agreement and without disruption or delay. At a minimum, Supplier will ensure that such contingency plan avoids sole source suppliers for any raw materials or Components and if any raw material or Component is sole sourced then Supplier will maintain an excess supply of the same at all times in an appropriate quantity relative to the Forecasts. Upon execution of this Agreement and, thereafter, upon Eargo’s request, Supplier will provide a copy of its then-current contingency plan to Eargo for review. Eargo reserves the right to propose reasonable changes or adjustments to the contingency plan which Supplier will adopt and be prepared to implement at its own cost. If Eargo requests to review the contingency plan, then the contingency plan is subject to Eargo’s approval before it may be relied upon by Supplier. Any changes to the contingency plan as approved by Eargo will follow the ECO process as set forth in Section 5.

13

6.7. Manufacturing Facilities/Inspection. Supplier will provide, regularly during the Term and more frequently as and when requested by Eargo, copies of all manufacturing documentation, including but not limited to documentation pertaining to the Manufacturing Process, created by Supplier, for which Eargo will have unrestricted rights to use the same. In addition, and without limiting, Eargo’s other rights in Section 22.4.2 below, Eargo or its designee may, from time to time, inspect Supplier’s facilities, operations and systems (and the facilities, operations and systems of its Subcontractors) to verify that the Products and Components are of appropriate quality and otherwise meet the requirements of this Agreement and that such facilities, operations and systems meet the Policies, and Eargo’s social accountability and safety standards. Eargo will be under no obligation to purchase or otherwise accept any Units that are produced (whether in whole or in part) in a facility or under any operations, methodology or systems that do not meet the Policies or Eargo’s social accountability or safety standards. If an Epidemic Failure occurs, Supplier will bear the costs of any such inspections made by Eargo [***]. Inspections that are conducted, or not conducted, will not affect any of Eargo’s rights under this Agreement.

6.8. Unauthorized Distribution and Counterfeit Goods. Supplier represents and warrants continuously throughout the Term that it will not, and will not permit any third party, including Supplier Parties, to: (a) distribute, or otherwise make any Units of the Product, available to any third party, other than to an Eargo Affiliate or Approved Buyer, as contemplated by this Agreement and the applicable SOW; (b) use a Prototype, First Article (including an Approved First Article), the Product, or any Components, to develop or manufacture a product or other good that is identical or confusingly similar to the Product(s); (c) create, manufacture or distribute any goods (other than the Products) bearing the Marks, or (d) attempt to create, manufacture or distribute any counterfeit version(s) of the Product(s). In the event that Eargo discovers that Supplier or any Supplier Parties have breached or are attempting to breach the warranties in this Section 6.8, in addition to (and not in lieu of) all of Eargo’s rights and remedies under this Agreement and otherwise, Eargo will be entitled to seek and obtain injunctive and equitable relief, reimbursement of attorneys’ fees, court costs, and all costs incurred by or on behalf of Eargo to protect the Marks or recover any Products or to confiscate any counterfeit goods. Supplier will immediately notify Eargo of any suspected or actual breach of this Section 6.8 by any Supplier Parties, and will cooperate with Eargo in any action that it may take against such Supplier Parties.

6.9. Notice of Changes and End of Life. Supplier will provide Eargo with no less than [***] advance written notice whenever a Component, Hardware or Software is planned to end of life, provided that if Supplier has been notified by the Approved Vendor(s) or any other applicable vendors (as permitted in Section 3.3) earlier than [***] prior to the planned end of life then Supplier will provide such earlier notice to Eargo. In the event of a change to any Component, Hardware or Software, Supplier will provide Eargo a written, detailed end of life plan that will include, without limitation, [***] to maintain the existing configuration for a reasonable length of time that will be no shorter than [***]. In all cases, Supplier will conduct extensive testing to ensure the replacement Components, Hardware or Software meets Supplier’s and Eargo’s quality standards and will not incorporate any new Components, Hardware or Software into the applicable Product without Eargo’s prior written consent and providing Eargo with the opportunity to re-qualify the Components, Hardware or Software and the manufacturing line therefor, including without limitation the Manufacturing Process for such Components, Hardware or Software, in Eargo’s sole discretion.

7. Packaging.

7.1. Requirements. Supplier will comply with all of Eargo’s approval requirements and applicable packaging and labeling instructions and requirements, including as may be set forth in the applicable Specifications, SOW or Policies. In addition, Supplier will select packaging and labeling that complies with environment regulations, to the extent such selection does not conflict with the applicable Specifications, SOW or Policies. Eargo will be solely responsible for providing the applicable packaging and labeling requirements to Supplier, however, if no requirements are provided, Supplier will ensure that the Units are packaged, marked and labeled in accordance with [***] and Eargo’s then-current branding and usage guidelines for the Marks, including marking the Units and packaging with the country of origin as required by applicable law, and, where appropriate, provide a certificate of origin and any other documents required by customs clearance and/or for tax purposes, along with all required shipping documentation. Supplier is not authorized to and will not print any of Supplier’s own trade names, trademarks, or logos on any Units without Eargo’s prior written consent, in each instance, which may be withheld at Eargo’s sole discretion. In all events, Supplier must include a valid packing slip number or package ID on each package or shipment of Units. For clarity, Supplier understands that, unless Eargo directs Supplier otherwise, Supplier will not include any sales documentation within any package or shipment of Units, including shipments that are to be delivered to Eargo, its Affiliate, or an Approved Buyer. If Supplier delivers a Unit that does not meet the packaging and labeling requirements of this Agreement, the applicable Specifications, SOW or Policies, Eargo may reject the Units and return such Units to Supplier for replacement by Supplier at Supplier’s sole cost and expense, or charge and bill to Supplier all repackaging and relabeling costs and expenses incurred by Eargo as a result of Supplier’s failure to comply with the packaging and labeling requirements of this Agreement.

7.2. Outbound Quality Control. Supplier will inspect each and every Unit prior to shipment to verify that each such Unit is in Compliance. If Supplier discovers that any or all of the Units are not in Compliance, Supplier will immediately replace the non-conforming Units with Units that are in Compliance prior to shipment. Supplier understands that any failure to conduct proper quality control and address Compliance prior to shipment will be at Supplier’s sole risk, cost and expense.

7.3. Documentation. To the extent, if any, Eargo requires any information of Supplier for the Documentation for the Products, Supplier will promptly comply with Eargo’s requests and furnish the required information. Supplier acknowledges and agrees that Eargo has no obligation whatsoever to provide specific credit or reference to Supplier in the Documentation for the Products but may do so if Eargo concludes that doing so is required under applicable law or is generally required under Eargo’s own Policies or preferred practices.

Supplier will accept and implement all of the above changes, as applicable.

8.3. Order Cancellation. If Eargo cancels any Purchase Order before Supplier or any authorized Subcontractors has placed non-cancelable orders for Components for the Units, or has commenced actual manufacturing of the Units ordered under such Purchase Order, Eargo will have no liability for such Units or payment under the affected Purchase Order(s). Except where otherwise permitted in this Agreement, including under Section 8.2, if Eargo cancels any Purchase Order after Supplier or its authorized Subcontractors has placed orders for Components or raw materials for the Units, or commenced actual manufacturing of the Units ordered within authorized Product lead times, Eargo will [***] for any non-cancellable or non-refundable Components or raw materials that have been procured within authorized Product lead times. Upon Eargo’s written request, if Eargo intends to reorder all or any portion of the Units covered by a cancelled Purchase Order within [***] of cancellation of such Purchase Order, Supplier will hold any non-cancellable and non-refundable Components or raw materials at a carrying cost not to exceed [***] of the non-cancellable and non-refundable Component or raw material value per [***], as applicable.

8.4. Buyers. Any of Eargo’s Affiliate(s) or the Approved Buyer(s) purchasing pursuant to this Agreement may purchase Units under the same terms as those in this Agreement, including, but not limited to, the Unit Price, and may otherwise act under the same terms as those in this Agreement that apply to Eargo. Eargo’s Affiliate(s) and the Approved Buyer(s) are entitled to the benefits and protections of the delivery, compliance, indemnity, representations and warranties, and remedies provisions of this Agreement to the same extent as Eargo. Further, Eargo is entitled to all rights under this Agreement for all Units purchased by Eargo’s Affiliate(s) and Approved Buyer(s) as if Eargo had purchased the Units directly from the Supplier. When any of Eargo’s Affiliate(s) or the Approved Buyer(s) are acting as this Section 8.4 allows, this Agreement’s terms will govern Supplier’s dealings with such Affiliate(s) or Approved Buyer(s), and separate agreements that Supplier may have with Approved Buyer(s) will not apply to those dealings. Notwithstanding anything to the contrary, (a) Supplier will not disclose or otherwise enable any

16

Approved Buyer(s) to access, view, or use any Confidential Information of Eargo, or the terms or conditions of this Agreement, except to the extent expressly authorized by Eargo in advance and in writing; and (b) under no circumstances will any Approved Buyer have authority to issue any approvals, consents, or notices where such approvals, consents, or notices from Eargo are required under this Agreement.

Quantities of Units purchased by Eargo’s Affiliate(s) and Approved Buyer(s) will be included when determining the total volume of Eargo’s purchases under this Agreement In no event will Supplier (and Supplier acknowledges that it has no rights to) sell or otherwise make available any Units to parties other than to Eargo, its Affiliate(s) and the Approved Buyer(s).

8.5. Timely Performance. Supplier acknowledges that time is of the essence regarding the performance of Supplier’s obligations under this Agreement. If Supplier has any knowledge that anything has prevented or may prevent or threaten to prevent its timely performance under this Agreement or any Purchase Order or SOW, Supplier will immediately notify Eargo and include all relevant information concerning the delay or potential delay. Such notification will not operate to relieve Supplier’s obligation to deliver by the Delivery Date unless Eargo agrees otherwise in writing, rather the notice is intended solely to allow the parties to plan for addressing the possible delay.

8.6. No Guarantees. Supplier acknowledges and agrees that Eargo, its Affiliate(s), and the Approved Buyer(s) make no commitment, whether express or implied, to issue any Purchase Orders for Units under this Agreement, and are under no obligation to do so, or as to the frequency, quantity or value of any Purchase Orders that may be issued under this Agreement.

Detailed packaging specifications may be set forth in a SOW. Supplier will ship the Units only via freight carriers that are selected or pre-approved by Eargo, and Supplier will manage all shipments directly with Eargo’s preferred freight forwarder. Supplier will mark the Units and packaging with

17

the country of origin as required by applicable law, and provide a certificate of origin and any other documents required by customs clearance and/or tax purposes. For the avoidance of doubt, Eargo will be solely responsible for specifying any labeling of Units, pursuant to Section 7 above, and Supplier is responsible for adhering to such labeling instructions. Supplier will be responsible for all losses or damages caused or due to any errors or defects in packaging or transportation.

9.3. Late Delivery. If Supplier’s ability to manufacture and deliver any Units in accordance with the then-current Forecast is, or is likely to be, constrained for any reason, Supplier will promptly notify Eargo, in writing, of the constraint, provide a detailed description of Supplier’s plan to resolve it, and provide Eargo with [***] updates regarding the steps Supplier has taken to resolve the constraint.

Supplier agrees that any duties and taxes that may be recoverable by the Supplier will not be charged or collected from Eargo.

10. Inspection and Acceptance.

10.1. Inspection and Acceptance. Upon receipt of Units under each delivery, Eargo will inspect such Units within [***] for obvious damage or defects (“Initial Inspection”). If all or any such Units fail the Initial Inspection then the shipment will be rejected and Acceptance will not be met. If all such Units meet Initial Inspection then Eargo will engage in further testing of the Units for a period of [***] following the Initial Inspection (“Test Period”) to determine whether such Units are in Compliance and to validate that such Units are not the subject of a government or manufacturer recall. If (individual Units or entire lots) are not in Compliance as determined by Eargo, its Affiliate(s) or Approved Buyer(s), as applicable, during the Test Period, then the Units will be rejected and Acceptance will not be met; in which case, Eargo may return such shipment and require a re-shipment of the conforming Units as detailed in Section 10.2 below. Before the end of the Test Period, Eargo, its Affiliate or Approved Buyer, as applicable, will notify Supplier of either its acceptance of the Units (“Acceptance”) or describe in reasonable detail why the Units are not in Compliance. Acceptance does not waive any of Eargo’s other rights or remedies under this Agreement with respect to such Units. Supplier understands that Eargo’s silence or payment of any invoices will not be deemed Acceptance of any Units.

18

10.2. Correction. If Eargo notifies Supplier that a Unit has failed Initial Inspection, is not in Compliance or has otherwise not met Acceptance, or if such Unit is the subject of a government or manufacturer’s recall, Eargo may at its sole discretion exercise one or more of the following remedies: (a) retain such Unit for correction by Supplier or another third party, in which event, Supplier will reimburse Eargo for all costs and expenses reasonably incurred by Eargo in connection with such correction; (b) retain such Unit as delivered, with an [***] to account for the diminished value of such Unit; (c) return such Unit to Supplier for correction or replacement by Supplier at Supplier’s sole cost and expense, including but not limited to all shipping costs associated with delivery of the Units to Eargo and return of the Units to Supplier, and Supplier will comply with Eargo’s instruction, if any, on how to correct or replace such Units; (d) return such Units to Supplier for full credit or refund, as elected by Eargo; (e) purchase from others in substitution for such Units, in which event, Supplier will promptly pay to Eargo the costs of the substitute products in excess of the Unit Price for such Units; and/or (f) terminate the Purchase Order or SOW with respect to such Units at no charge and without liability (Supplier will continue to perform such Purchase Order or SOW to the extent not terminated by Eargo), in which event, Eargo may request, and Supplier will upon such request promptly deliver to Eargo any completed and partially completed Units (and all related material and information) and transfer to Eargo all tangible property rights, title and interests in such Units as directed by Eargo [***]. Eargo will be entitled to recover from Supplier all costs and expenses reasonably incurred by Eargo in connection with any of the foregoing (including, without limitation, all costs to return such Units to Supplier). Eargo may recover any amount owed by Supplier to Eargo through, at Eargo’s election, credit, setoff, invoice, refund, cash payment, or otherwise.

10.3. Rejection of Replacement Products.

11.4. Cost Reduction. Eargo and Supplier will agree on a joint cost-reduction program throughout the first [***] of production of new Products. The program will consist of specific cost targets, specific project plans and timing, and specific cost-sharing schedules. After the first [***] of production of new Products, the parties will cooperate in good-faith to achieve a [***] cost reduction target of [***] for all delivered Products. BOM Cost and Value Added pricing will be reviewed [***] to ensure price reduction commitments are consistent with this provision and otherwise acceptable to Eargo. Supplier will provide data for the following [***] at least [***] prior to the then-current [***]-end. The parties will share the benefit of cost reductions of established Products (beyond the first [***] of production) per the following schedules:

20

11.4.1. BOM Cost reductions will be shared between the parties as follows: (a) if Supplier initiated the BOM Cost reduction within the first [***] of the Term, (i) Supplier receives [***] of the applicable BOM Cost reduction achieved for the first [***], [***] for the second [***], and [***] thereafter; and (ii) Eargo receives [***] for the first [***], [***] for the second [***], and [***] of the applicable BOM Cost reduction achieved thereafter; (c) if Supplier initiated the BOM Cost reduction after the first [***] of the Term, (i) Supplier receives [***] of the applicable BOM Cost reduction achieved for the first [***], and [***] thereafter; and (ii) Eargo receives [***] for the first [***] and [***] of the applicable BOM Cost reduction achieved thereafter; and (d) if Eargo initiated any BOM Cost reduction during the Term, (i) Supplier receives [***] for the first [***], and [***] thereafter; and (ii) Eargo receives [***] for the first [***], and [***] of the applicable BOM Cost reduction achieved thereafter.

11.4.2. Process improvements or labor cost reductions will be [***] between the parties as follows: Supplier will receive [***] of the applicable process improvement or labor cost reduction and Eargo will receive [***] of the applicable process improvement or labor cost reduction, [***].

11.4.3. If Eargo cancels any Purchase Order, Supplier will use [***] to mitigate the costs in connection with and other effects of such cancellation, including without limitation canceling orders for Components, returning Components (provided, however, that Supplier will not be obligated to attempt to return any Components which are, in the aggregate, worth less than [***]), ceasing the Manufacturing Process immediately, re-using, re-selling or selling for scrap any Components or raw materials and similar actions, and Eargo will [***] of the Units which Supplier is unable to mitigate.

11.5. Most Favored Pricing. If Supplier offers any more favorable term or condition to any other company than that which is offered to Eargo, then Supplier will concurrently extend equal or better terms and conditions to Eargo, and this Agreement and any applicable Purchase Order or SOW will be deemed amended to provide those terms to Eargo. Any amounts charged to Eargo in excess of prices offered by Supplier to any other company or partner for the Product will promptly be refunded or credited to Eargo, at Eargo’s sole option.

11.6. Invoices. For each and every Order, Supplier will not invoice Eargo, its Affiliate, or Approved Buyer, as applicable, for Units under that Order until all Units required under that Order have been delivered in accordance with the Delivery Date and to the specified delivery location on the applicable Purchase Order, and such Units have passed Initial Inspection.

14. Confidential Information.

14.1. Meaning of Confidential Information. The parties agree that “Confidential Information” means any and all information (in any form or media) regarding a party’s, prospective, methods of operation, engineering methods and processes (including any information which may be obtained by a party by reverse engineering, decompiling or examining any Software or Hardware provided by the other party under this Agreement), programs and databases, patents and designs, billing rates, billing procedures, identities of and contact information regarding Approved Vendors and Approved Buyer(s), business methods, finances, management, and any other business information relating to such party (whether constituting a trade secret or proprietary or otherwise) which has value to such party and is treated by such party as being confidential. A party receiving Confidential Information under this Agreement is referred to as the “Receiving Party” and a party disclosing, furnishing or making Confidential Information available to the other party or its Representatives pursuant to this Agreement is referred to as the “Disclosing Party.” For purposes of this Agreement, “Person” will mean and include any individual, partnership, association, corporation, trust, unincorporated organization, limited liability company or any other business entity or enterprise; and “Representative” will mean a party’s employees, agents, or representatives, including without limitation, financial advisors, lawyers, accountants, experts and consultants. Each party acknowledges that Confidential Information of a Disclosing Party is the property of the Disclosing Party, provided, however, that in no event is Eargo Property to be considered included within or construed as the Confidential Information of Supplier. The terms of this Agreement, including all Specifications, Eargo Data, content of Reports, Forecasts, Prototypes or samples of the Product, Prototypes, First Articles, Approved First Articles, and any not previously publicly disclosed information about Eargo’s or its Affiliate(s)’ respective business, finances, information systems, software or technology provided by or on behalf of Eargo to Supplier under this Agreement will be deemed Confidential Information of Eargo without any further marking or designation and regardless of the lack of the same.

14.2. Non-Disclosure Obligation. Except as expressly authorized herein, the Receiving Party will hold in confidence and not use or disclose, and ensure that its Representatives do not use or disclose, any Confidential Information of the Disclosing Party, except solely for the purpose of performing the Receiving Party’s obligations under this Agreement, but not otherwise. For a period of [***] from the date of the last disclosure under this Agreement, the Receiving Party: (a) will maintain as confidential all Confidential Information disclosed to it by the Disclosing Party, (b) will not, directly or indirectly, disclose any such Confidential Information to any Person other than (i) those Representatives of the Receiving Party whose duties under this Agreement justify the need to know such Confidential Information and then only after each Representative has agreed to be bound by this Confidentiality Agreement, in writing, and clearly understands his or her obligation to protect the confidentiality of such Confidential Information and to restrict the use of such Confidential Information, and (ii) if Supplier is the Receiving Party, to an Approved Vendor solely for the purpose of obtaining information from that Approved Vendor necessary for Supplier to prepare a Price Quotation, provided that each such Approved Vendor clearly understands its obligation to protect the confidentiality of such Confidential Information and to restrict the use of such Confidential Information, and (c) will treat such Confidential Information with the same degree of care as it treats its own Confidential Information (but in no case with less than a reasonable degree of care).

26

14.3. Exceptions to Confidential Information. The Receiving Party’s nondisclosure obligation will not apply to any information, regardless of whether marked or asserted to be Confidential Information by the Disclosing Party, which the Receiving Party can document with written records: (a) was rightfully in its possession or known to it prior to receipt of the Confidential Information; (b) is or has become public knowledge through no fault, act or omission of the Receiving Party; (c) is rightfully obtained by the Receiving Party from a third party without breach of any confidentiality obligation; or (d) is independently developed by employees of the Receiving Party who had no access to such information.

14.4. Compulsory Disclosures. If the Receiving Party or its Representatives is required or becomes legally compelled to disclose any of the Confidential Information pursuant to a regulation, law or court order, it will provide the Disclosing Party with prompt written notice so the Disclosing Party may seek appropriate protective orders. If a protective order or other remedy is not obtained, then only that part of the Confidential Information that is legally required to be furnished will be furnished, and reasonable efforts will be made to obtain reliable assurances of confidentiality.

14.5. Return of Materials. Except as otherwise set forth in this Agreement, all Confidential Information supplied by the Disclosing Party will remain the property of the Disclosing Party, and upon expiration or termination of this Agreement, for any or no reason, or upon earlier request by the Disclosing Party, will be promptly destroyed (with certification of such destruction in writing) or (if specifically requested in writing) returned by the Receiving Party, including all documents or materials of any nature in the Receiving Party’s possession, custody or control (regardless of the media in which such documents or materials are stored), including Confidential Information of the Disclosing Party and its Affiliate(s), that have been furnished by or on behalf of the Disclosing Party to the Receiving Party, or reproduced or developed by the Receiving Party or its authorized Subcontractors based on the Disclosing Party’s Confidential Information, provided, however, the Receiving Party may maintain copies of any such Confidential Information to the extent required for backup, disaster recovery, or business continuity; in such event the obligations of confidentiality hereunder will survive until such copies are destroyed.

14.6. Injunctive Relief. The Receiving Party acknowledges that disclosure of Confidential Information may cause substantial harm for which damages alone may not be a sufficient remedy, and therefore upon any such disclosure by the Receiving Party, the Disclosing Party will be entitled to seek appropriate equitable relief in addition to whatever other remedies it might have at law.
