 Exhibit 10.9 

INDEMNIFICATION AND ADVANCEMENT AGREEMENT 

This Indemnification and Advancement Agreement (“Agreement”) is made as of
                    , 20         by and between Eargo, Inc., a Delaware corporation (the
“Company”), and                         , [a member of the Board of Directors/an officer/an employee] of
the Company (“Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements between the Company and Indemnitee covering indemnification and advancement. 

RECITALS 
 WHEREAS, the
Board of Directors of the Company (the “Board”) believes that highly competent persons have become more reluctant to serve publicly-held corporations as directors, officers, or in other capacities unless they are provided with
adequate protection through insurance or adequate indemnification and advancement of expenses against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an
ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United
States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time,
directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought
only against the Company or business enterprise itself. The Bylaws and Certificate of Incorporation of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to
the General Corporation Law of the State of Delaware (the “DGCL”). The Bylaws, Certificate of Incorporation, and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby
contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification and advancement of expenses; 

WHEREAS, the uncertainties relating to such insurance, to indemnification, and to advancement of expenses may increase the difficulty of
attracting and retaining such persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such
persons is detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

 WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws, Certificate of
Incorporation and any resolutions adopted pursuant thereto, and is not a substitute therefor, nor diminishes or abrogates any rights of Indemnitee thereunder; and 

WHEREAS, Indemnitee does not regard the protection available under the Bylaws, Certificate of Incorporation, DGCL and insurance as adequate in
the present circumstances, and may not be willing to serve or continue to serve as an officer or director without adequate additional protection, and the Company desires Indemnitee to serve or continue to serve in such capacity. Indemnitee is
willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified and be advanced expenses. 

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree
as follows: 
 Section 1.    Services to the Company. Indemnitee agrees to serve as a
[director/officer/employee] of the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law). This Agreement does not create any
obligation on the Company to continue Indemnitee in such position and is not an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee. 

Section 2.    Definitions. As used in this Agreement: 

(a)    “Agent” means any person who is authorized by the Company or an Enterprise to act for or represent the
interests of the Company or an Enterprise, respectively. 
 (b)    A “Change in Control” occurs upon the

Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the Company’s then
outstanding securities unless the change in relative beneficial ownership of the Company’s securities by any Person results solely from a reduction in the aggregate number of outstanding shares of securities entitled to vote generally in the
election of directors; 
 ii.    Change in Board of Directors. During any period of two (2) consecutive years (not
including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement with the
Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least
two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to
constitute at least a majority of the members of the Board;

 iii.    Corporate Transactions. The effective date of a merger or
consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by

with the power to elect at least a majority of the board of directors or other governing body of such surviving entity; 

iv.    Liquidation. The approval by the stockholders of the Company of a complete liquidation of the Company or an

in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable in the good faith judgment of such counsel will be presumed conclusively to be reasonable.
Expenses, however, do not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee.

criminal, administrative, legislative, or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, potential party, non-party
witness or otherwise by reason of Indemnitee’s Corporate Status or by reason of any action taken by Indemnitee (or a failure to take action by Indemnitee) or of any action (or failure to act) on Indemnitee’s part while acting pursuant to
Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement. A
Proceeding also includes a situation the Indemnitee believes in good faith may lead to or culminate in the institution of a Proceeding. 

Section 3.    Indemnity in Third-Party Proceedings. The Company will indemnify Indemnitee in accordance with
the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 3, the Company will indemnify Indemnitee to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein,
if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal Proceeding had no reasonable cause to believe that Indemnitee’s conduct
was unlawful. 
 Section 4.    Indemnity in Proceedings by or in the Right of the Company. The Company will
indemnify Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant
to this Section 4, the Company will indemnify Indemnitee to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or
any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. The Company will not indemnify Indemnitee for Expenses under this
Section 4 related to any claim, issue or matter in a Proceeding for which Indemnitee has been finally adjudged by a court to be liable to the Company, unless, and only to the extent that, the Delaware Court of Chancery or any court in which the
Proceeding was brought determines upon application by Indemnitee that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 

Section 5.    Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any
other provisions of this Agreement, to the fullest extent permitted by applicable law, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection with any Proceeding the extent that
Indemnitee is successful, on the merits or otherwise. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the
Company will indemnify Indemnitee against 

  
 -5- 

 
all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent
permitted by law. For purposes of this Section 5 and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, will be deemed to be a successful result as to such claim,
issue or matter. 
 Section 6.    Indemnification For Expenses of a Witness. Notwithstanding any other
provision of this Agreement and to the fullest extent permitted by applicable law, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with any
Proceeding to which Indemnitee is not a party but to which Indemnitee is a witness, deponent, interviewee, or otherwise asked to participate. 

Section 7.    Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to
indemnification by the Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company will indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

Section 8.    Additional Indemnification. Notwithstanding any limitation in Sections 3, 4, or 5, the Company
will indemnify Indemnitee to the fullest extent permitted by applicable law (including but not limited to, the DGCL and any amendments to or replacements of the DGCL adopted after the date of this Agreement that expand the Company’s ability to
indemnify its officers and directors) if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor). 

Section 9.    Exclusions. Notwithstanding any provision in this Agreement, the Company is not obligated under
this Agreement to make any indemnification payment to Indemnitee in connection with any Proceeding: 
 (a)    for which
payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except to the extent provided in Section 16(b) of the Exchange Act and except with respect to any excess beyond the amount
paid under any insurance policy or other indemnity provision; or 
 (b)    for (i) an accounting of profits made
from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law, (ii) any reimbursement of the
Company by the Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such
reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase
and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act) or (iii) any reimbursement of the Company by Indemnitee of any compensation pursuant to any compensation recoupment or clawback policy adopted by
the Board or the compensation committee of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act; or 

  
 -6- 

 (c)    initiated by Indemnitee, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Proceeding or part of any Proceeding is to enforce Indemnitee’s rights to indemnification or
advancement, of Expenses, including a Proceeding (or any part of any Proceeding) initiated pursuant to Section 14 of this Agreement, (ii) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or
(iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 10.    Advances of Expenses. 

(a)    The Company will advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection
with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee or any Proceeding (or any part of any Proceeding) initiated by Indemnitee if (i) the Proceeding or part of any Proceeding is to enforce Indemnitee’s rights to
obtain indemnification or advancement of Expenses from the Company or Enterprise, including a proceeding initiated pursuant to Section 14 or (ii) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation.
The Company will advance the Expenses within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding. 

(b)    Advances will be unsecured and interest free. Indemnitee undertakes to repay the amounts advanced (without
interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company, thus Indemnitee qualifies for advances upon the execution of this Agreement and delivery to the Company. No other form of
undertaking is required other than the execution of this Agreement. The Company will make advances without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification
under the other provisions of this Agreement. 
 Section 11.    Procedure for Notification of Claim for
Indemnification or Advancement. 
 (a)    Indemnitee will notify the Company in writing of any Proceeding with
respect to which Indemnitee intends to seek indemnification or advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. Indemnitee will include in the written notification to
the Company a description of the nature of the Proceeding and the facts underlying the Proceeding and provide such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what
extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. Indemnitee’s failure to notify the Company will not relieve the Company from any obligation it may have to Indemnitee under this Agreement, and
any delay in so notifying the Company will not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company will, promptly upon receipt of such a request for indemnification, advise the Board in writing that
Indemnitee has requested indemnification or advancement. 

  
 -7- 

 (b)    The Company will be entitled to participate in the Proceeding at
its own expense. 
 Section 12.    Procedure Upon Application for Indemnification. 

(a)    Unless a Change of Control has occurred, the determination of Indemnitee’s entitlement to indemnification will
be made: 
 i.    by a majority vote of the Disinterested Directors, even though less than a quorum of the Board; 

ii.    by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even
though less than a quorum of the Board; 
 iii.     if there are no such Disinterested Directors or, if such
Disinterested Directors so direct, by written opinion provided by Independent Counsel selected by the Board; or 

iv.    if so directed by the Board, by the stockholders of the Company. 

(b)    If a Change in Control has occurred, the determination of Indemnitee’s entitlement to indemnification will be
made by written opinion provided by Independent Counsel selected by Indemnitee (unless Indemnitee requests such selection be made by the Board). 

(c)     The party selecting Independent Counsel pursuant to subsection (a)(iii) or (b) of this Section 12 will
provide written notice of the selection to the other party. The notified party may, within ten (10) days after receiving written notice of the selection of Independent Counsel, deliver to the selecting party a written objection to such
selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this
Agreement, and the objection will set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected will act as Independent Counsel. If such written objection is so made and substantiated,
the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within thirty (30) days after the later of
submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, Independent Counsel has not been selected or, if selected, any objection to has not been resolved,
either the Company or Indemnitee may petition the Delaware Court for the appointment as Independent Counsel of a person selected by such court or by such other person as such court designates. Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel will be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

  
 -8- 

 (d)    Indemnitee will cooperate with the person, persons or entity
making the determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise
protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. The Company will advance and pay any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity
making the indemnification determination irrespective of the determination as to Indemnitee’s entitlement to indemnification and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise
Indemnitee in writing of the determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which indemnification has been denied and providing a copy of any written opinion provided to the
Board by Independent Counsel. 
 (e)    If it is determined that Indemnitee is entitled to indemnification, the Company
will make payment to Indemnitee within ten (10) days after such determination. 

Section 13.    Presumptions and Effect of Certain Proceedings. 

(a)    In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity
making such determination will, to the fullest extent not prohibited by law, presume Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(a) of
this Agreement, and the Company will, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a
determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including
by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, will be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b)    If the determination of the Indemnitee’s entitlement to indemnification has not made pursuant to
Section 12 within sixty (60) days after the latter of (i) receipt by the Company of Indemnitee’s request for indemnification pursuant to Section 11(a) and (ii) the final disposition of the Proceeding for which
Indemnitee requested Indemnification (the “Determination Period”), the requisite determination of entitlement to indemnification will, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee will be
entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable law. The Determination Period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the
determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, the Determination Period may be
extended an additional fifteen (15) days if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a)(iv) of this Agreement. 

  
 -9- 

 (c)    The termination of any Proceeding or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, will not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee
to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that
Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 (d)    For purposes of any
determination of good faith, Indemnitee will be deemed to have acted in good faith if Indemnitee acted based on the records or books of account of the Company, its subsidiaries, or an Enterprise, including financial statements, or on information
supplied to Indemnitee by the directors or officers of the Company, its subsidiaries, or an Enterprise in the course of their duties, or on the advice of legal counsel for the Company, its subsidiaries, or an Enterprise or on information or records
given or reports made to the Company or an Enterprise by an independent certified public accountant or by an appraiser, financial advisor or other expert selected with reasonable care by or on behalf of the Company, its subsidiaries, or an
Enterprise. Further, Indemnitee will be deemed to have acted in a manner “not opposed to the best interests of the Company,” as referred to in this Agreement if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed
to be in the best interests of the participants and beneficiaries of an employee benefit plan. The provisions of this Section 13(d) is not exclusive and does not limit in any way the other circumstances in which the Indemnitee may be deemed to
have met the applicable standard of conduct set forth in this Agreement. 
 (e)    The knowledge and/or actions, or
failure to act, of any director, officer, trustee, partner, managing member, fiduciary, agent or employee of the Enterprise may not be imputed to Indemnitee for purposes of determining Indemnitee’s right to indemnification under this Agreement.

 Section 14.    Remedies of Indemnitee. 

(a)    Indemnitee may commence litigation against the Company in the Delaware Court of Chancery to obtain indemnification
or advancement of Expenses provided by this Agreement in the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) the Company
does not advance Expenses pursuant to Section 10 of this Agreement, (iii) the determination of entitlement to indemnification is not made pursuant to Section 12 of this Agreement within the Determination Period, (iv) the Company
does not indemnify Indemnitee pursuant to Section 5 or 6 or the second to last sentence of Section 12(d) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) the Company does not
indemnify Indemnitee pursuant to Section 3, 4, 7, or 8 of this Agreement within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any
other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding 

  
 -10- 

 
designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder. Alternatively, Indemnitee, at Indemnitee’s option, may seek
an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee must commence such Proceeding seeking an adjudication or an award in arbitration within
180 days following the date on which Indemnitee first has the right to commence such Proceeding pursuant to this Section 14(a); provided, however, that the foregoing clause does not apply in respect of a Proceeding brought by
Indemnitee to enforce Indemnitee’s rights under Section 5 of this Agreement. The Company will not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b)    If a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 will be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee may not be prejudiced by reason of that
adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14 the Company will have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be and
will not introduce evidence of the determination made pursuant to Section 12 of this Agreement. 
 (c)    If a
determination is made pursuant to Section 12 of this Agreement that Indemnitee is entitled to indemnification, the Company will be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d)    The Company is, to the fullest extent not prohibited
by law, precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and will stipulate in any such court
or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 
 (e)    It is the
intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by
litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company, to the fullest extent permitted by law, will (within ten (10) days
after receipt by the Company of a written request therefor) advance to Indemnitee such Expenses which are incurred by Indemnitee in connection with any action concerning this Agreement, Indemnitee’s right to indemnification or advancement of
Expenses from the Company, or concerning any directors’ and officers’ liability insurance policies maintained by the Company. and will indemnify Indemnitee against any and all such Expenses unless the court determines that each of the
Indemnitee’s claims in such Proceeding were made in bad faith or were frivolous or are prohibited by law.

 Section 15.    Establishment of Trust. 

(a)    In the event of a Potential Change in Control or a Change in Control, the Company will, upon written request by
Indemnitee, create a trust for the benefit of Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee will fund such Trust in an amount sufficient to satisfy the reasonably anticipated indemnification and
advancement obligations of the Company to the Indemnitee in connection with any Proceeding for which Indemnitee has demanded indemnification and/or advancement prior to the Potential Change in Control or Change in Control (the “Funding
Obligation”). The trustee of the Trust (the “Trustee”) will be a bank or trust company or other individual or entity chosen by the Indemnitee and reasonably acceptable to the Company. Nothing in this Section 15
relieves the Company of any of its obligations under this Agreement. 
 (b)    The amount or amounts to be deposited in
the Trust pursuant to the Funding Obligation will be determined by mutual agreement of the Indemnitee and the Company or, if the Company and the Indemnitee are unable to reach such an agreement, by Independent Counsel selected in accordance with
Section 12(b) of this Agreement. The terms of the Trust will provide that, except upon the consent of both the Indemnitee and the Company, upon a Change in Control: (i) the Trust may not be revoked, or the principal thereof invaded,
without the written consent of the Indemnitee; (ii) the Trustee will advance, to the fullest extent permitted by applicable law, within two (2) business days of a request by the Indemnitee; (iii) the Company will continue to fund the
Trust in accordance with the Funding Obligation; (iv) the Trustee will promptly pay to the Indemnitee all amounts for which the Indemnitee is entitled to indemnification pursuant to this Agreement or otherwise; and (v) all unexpended funds
in such Trust revert to the Company upon mutual agreement by the Indemnitee and the Company or, if the Indemnitee and the Company are unable to reach such an agreement, by Independent Counsel selected in accordance with Section 12(b) of this
Agreement, that the Indemnitee has been fully indemnified under the terms of this Agreement. New York law (without regard to its conflicts of laws rules) governs the Trust and the Trustee will consent to the exclusive jurisdiction of Delaware Court
of Chancery, in accordance with Section 25 of this Agreement. 
 Section 16.    Non-exclusivity; Survival of Rights; Insurance; Subrogation. 
 (a)    The
indemnification and advancement of Expenses provided by this Agreement are not exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of
stockholders or a resolution of directors, or otherwise. The indemnification and advancement of Expenses provided by this Agreement may not be limited or restricted by any amendment, alteration or repeal of this Agreement in any way with respect to
any action taken or omitted by Indemnitee in Indemnitee’s Corporate Status occurring prior to any amendment, alteration or repeal of this Agreement. To the extent that a change in Delaware law, whether by statute or judicial decision, permits
greater indemnification or advancement of Expenses than would be afforded currently under the Bylaws, Certificate of Incorporation, or this Agreement, it is the intent of the parties hereto that Indemnitee enjoy by this Agreement the greater
benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy is cumulative and in addition to every other right and remedy given hereunder or now
or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or employment of any other right or remedy.

 (b)    The Company hereby acknowledges that Indemnitee may have certain
rights to indemnification, advancement of Expenses and/or insurance provided by one or more Persons with whom or which Indemnitee may be associated ([including without limitation [Fund names(s)],] the “Fund Indemnitors”). 

i.    The Company hereby acknowledges and agrees: 

  1)    the Company is the indemnitor of first resort with respect to any request for indemnification or
advancement of Expenses made pursuant to this Agreement concerning any Proceeding arising from or related to Indemnitee’s Corporate Status with the Company; 

  2)     the Company is primarily liable for all indemnification and indemnification or advancement of Expenses
obligations for any Proceeding arising from or related to Indemnitee’s Corporate Status, whether created by law, organizational or constituent documents, contract (including this Agreement) or otherwise; 

  3)    any obligation of any other Persons with whom or which Indemnitee may be associated (including, without
limitation, any Fund Indemnitor) to indemnify Indemnitee and/or advance Expenses to Indemnitee in respect of any proceeding are secondary to the obligations of the Company’s obligations; 

  4)    the Company will indemnify Indemnitee and advance Expenses to Indemnitee hereunder to the fullest
extent provided herein without regard to any rights Indemnitee may have against any other Person with whom or which Indemnitee may be associated (including, any Fund Indemnitor) or insurer of any such Person; and 

ii.    the Company irrevocably waives, relinquishes and releases (A) any other Person with whom or which Indemnitee
may be associated (including, without limitation, any Fund Indemnitor) from any claim of contribution, subrogation, reimbursement, exoneration or indemnification, or any other recovery of any kind in respect of amounts paid by the Company to
Indemnitee pursuant to this Agreement and (B) any right to participate in any claim or remedy of Indemnitee against any Fund Indemnitor (or former Fund Indemnitor), whether or not such claim, remedy or right arises in equity or under contract,
statute or common law, including, without limitation, the right to take or receive from any Fund Indemnitor (or former Fund Indemnitor), directly or indirectly, in cash or other property or by set-off or in
any other manner, payment or security on account of such claim, remedy or right. 
 iii.    In the event any other
Person with whom or which Indemnitee may be associated (including, without limitation, any Fund Indemnitor) or their insurers advances or extinguishes any liability or loss for Indemnitee, the payor has a right of subrogation against the Company or
its insurers for all amounts so paid which would otherwise be payable by the Company or its insurers under this Agreement. In no event will payment by any other Person with whom or which Indemnitee may be associated (including, without limitation,
any Fund Indemnitor) or their insurers affect the obligations of the Company hereunder or shift primary liability for the Company’s obligation to indemnify or advance of Expenses to any other Person with whom or which Indemnitee may be
associated (including, without limitation, any Fund Indemnitor). 

  
 -13- 

 iv.    Any indemnification or advancement of Expenses provided by any
other Person with whom or which Indemnitee may be associated (including, without limitation, any Fund Indemnitor) is specifically in excess over the Company’s obligation to indemnify and advance Expenses or any valid and collectible insurance
(including but not limited to any malpractice insurance or professional errors and omissions insurance) provided by the Company. 

(c)    To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, officers, employees, or agents of the Enterprise, the Company will obtain a policy or policies covering Indemnitee to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or
policies, including coverage in the event the Company does not or cannot, for any reason, indemnify or advance Expenses to Indemnitee as required by this Agreement. If, at the time of the receipt of a notice of a claim pursuant to this Agreement,
the Company has director and officer liability insurance in effect, the Company will give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the
respective policies. The Company will thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.
Indemnitee agrees to assist the Company efforts to cause the insurers to pay such amounts and will comply with the terms of such policies, including selection of approved panel counsel, if required. 

(d)    The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee for any Proceeding
concerning Indemnitee’s Corporate Status with an Enterprise will be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such Enterprise. The Company and Indemnitee intend that any such
Enterprise (and its insurers) be the indemnitor of first resort with respect to indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. The Company’s
obligation to indemnify and advance Expenses to Indemnitee is secondary to the obligations the Enterprise or its insurers owe to Indemnitee. Indemnitee agrees to take all reasonably necessary and desirable action to obtain from an Enterprise
indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. 

(e)    In the event of any payment made by the Company under this Agreement, the Company will be subrogated to the extent
of such payment to all of the rights of recovery of Indemnitee from any Enterprise or insurance carrier. Indemnitee will execute all papers required and take all action necessary to secure such rights, including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights. 
 Section 17.    Duration of
Agreement. This Agreement continues until and terminates upon the later of: (a) ten (10) years after the date that Indemnitee ceases to serve as a director [director/officer/employee] of the Company or (b) one (1) year after the final
termination of any Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant

  
 -14- 

 
to Section 14 of this Agreement relating thereto. The indemnification and advancement of Expenses rights provided by or granted pursuant to this Agreement are binding upon and be enforceable
by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), continue as to an
Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other Enterprise, and inure to the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and other
legal representatives. 
 Section 18.    Severability. If any provision or provisions of this Agreement is
held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement
containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will not in any way be affected or impaired thereby and remain enforceable to the fullest extent permitted by law;
(b) such provision or provisions will be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of
this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will be construed so as to
give effect to the intent manifested thereby. 
 Section 19.    Interpretation. Any ambiguity in the terms
of this Agreement will be resolved in favor of Indemnitee and in a manner to provide the maximum indemnification and advancement of Expenses permitted by law. The Company and Indemnitee intend that this Agreement provide to the fullest extent
permitted by law for indemnification in excess of that expressly provided, without limitation, by the Certificate of Incorporation, the Bylaws, vote of the Company stockholders or disinterested directors, or applicable law. 

Section 20.    Enforcement. 

(a)    The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations
imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving or continuing to serve as a director or officer of the
Company. 
 (b)    This Agreement constitutes the entire agreement between the parties hereto with respect to the
subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in
furtherance of the Certificate of Incorporation, the Bylaws and applicable law, and is not a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

Section 21.    Modification and Waiver. No supplement, modification or amendment of this Agreement is binding
unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement will be deemed or constitutes a waiver of any other provisions of this Agreement nor will any waiver constitute a continuing waiver.

promptly to notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of
Expenses covered hereunder. The failure of Indemnitee to so notify the Company does not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise.

in writing and will be deemed to have been duly given if (a) delivered by hand to the other party, (b) sent by reputable overnight courier to the other party or (c) sent by facsimile transmission or electronic mail, with receipt of

Section 24.    Contribution. To the fullest extent permissible under applicable law, if the indemnification
provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, will contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes,
amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such
Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its
directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

parties are governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 14(a) of
this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or Proceeding arising out of or in connection with this Agreement may be brought

existence of this Agreement. 
 Section 27.    Headings. The headings of this Agreement are inserted for
convenience only and do not constitute part of this Agreement or affect the construction thereof.

a timely, professional and workmanlike manner pursuant to the highest industry standards in accordance with the terms of each Purchase Order, Statement of Work, the BOM, Specifications, and this Agreement. 

2.2. Statements of Work. Supplier will perform all Services that are incidental to the Manufacturing Process and the assembly,
production, testing, labeling, packaging and delivery of Units in accordance with the Specifications, the terms of this Agreement, the applicable Orders and, if any, the corresponding SOW(s). For all other Services, Supplier will perform such other
Services in accordance with the Specifications, as applicable, and the requirements and deadlines in the applicable SOW(s). The form of SOW is set forth in Exhibit A to this Agreement. SOWs may be entered into under this
Agreement by Eargo or any Affiliate. Each SOW will include all its relevant Appendices listed above in complete form. Each SOW covering a Product must include the relevant Specifications for that particular Product as Appendix 1 to that SOW.
Each SOW will remain in effect until termination in accordance with this Agreement or completed as required by its terms. Any SOW that does not include the applicable Appendices in complete form, does not include Specifications in complete form
under Appendix 1 thereto, or is not executed by Eargo (or its Affiliate, as the case may be) will be of no force and effect and will not be binding upon Eargo. The entity that executes a SOW with Supplier will be considered “Eargo”
for all purposes of the SOW and this Agreement and the SOW will be considered a two party agreement between Supplier and such entity. 

2.3. Specifications. The Specifications set forth under each SOW are binding upon Supplier and Supplier will manufacture Units in
accordance with the Specifications. Supplier will not make any change or modification to the Specifications, to any Components described therein, or to the Units (including, without limitation, changes in form, fit, function, design, appearance or
place of manufacture of the Units or changes [***]. Supplier agrees that its capability to comply, and actual compliance with, the Specifications in manufacturing the Products is a material term of this Agreement, without which Eargo would not have
selected Supplier, and a condition precedent to any obligation Eargo (or its Affiliate(s) or Authorized Buyer(s)) may otherwise have to pay Supplier for the applicable Products manufactured or shipped. 

2.4. Logistics. 
 2.4.1.
Supplier will be responsible for procuring (from Eargo and/or the Approved Vendors, if any, as set forth in the applicable SOW) all Components and raw materials required for the Products. Supplier will be responsible for all costs and expenses
associated with such procurement and delivery of Components to Supplier, all costs associated with configuration, assembly, production, manufacturing, testing, packaging, and shipping the Products based on the Approved First Article. Supplier is
responsible for all costs associated with secure storage and warehousing of all Products, including Components not yet assembled with Products, in accordance with this Agreement. Supplier will be responsible for establishing relationships with
Eargo’s designated freight forwarders and carriers for the shipment and delivery of all Units. Notwithstanding anything to the contrary, Supplier will first procure any Components, raw materials and/or equipment required for the Products from
Eargo, prior to any Approved Vendors, or any other vendors (as permitted in Section 3.3).

 2.4.2. If Eargo determines, in its sole discretion, that a Product has reached stable
production volumes in a specific region, the parties will work together to establish a hub strategy for the specified region(s). In addition, the parties will mutually agree upon incorporating any applicable hub, and electronic database interchange
(EDI) terms into this Agreement, including without limitation, any hub fees that are necessary for determining the Unit Price (as defined below) of any applicable Product(s). In this event, Supplier acknowledges and agrees that it will not include
or increase any applicable hub fees without Eargo’s prior written approval. 
 2.5. Bill of Materials. Prior to the commencement
of any Services, Eargo and Supplier will agree in writing on a bill of materials for the Product that itemizes the Components, Approved Vendors, and other materials necessary for the manufacture, assembly, testing and packaging of the Products and
which, if signed by Eargo, is made a part of the applicable Specifications (the “BOM”). Each BOM will reference the applicable SOW and Specifications to which it pertains. The BOM may also specify the
lead-times for the Products. The parties may update the BOM from time to time solely by mutual written agreement. A BOM that is not signed by Eargo is not accepted by Eargo and is not made a part of the
applicable SOW or Specifications. 
 2.6. Manufacturer Warranty Support. If and as required by Eargo under a SOW, Supplier will
provide manufacturer warranty support for the Products. In that event, Supplier agrees that manufacturer warranty support for the Products will include and consist of those Services outlined in Appendix 8 to the applicable SOW. Supplier will
ensure that all manufacturer warranty support for the Products will be provided in accordance with the service levels set forth in Appendix 8 of the applicable SOW (“Service Levels”). If Supplier fails to meet the Service
Levels in any calendar month (“Service Level Default”), in addition to its other rights and remedies under this Agreement and at law, Eargo will be entitled to receive service level credits from Supplier as set forth in Appendix
8 of the applicable SOW and Supplier will be required to pay directly or reimburse Eargo (at Eargo’s sole option) for any and all costs and expenses incurred by Eargo in the engagement of third party provider(s) to provide manufacturer
warranty support for the Products at the level required under Appendix 8. Following the termination or expiration of the Agreement, Supplier will within [***] from the date of termination refund to Eargo the amount of any unused credits,
together with the amount of any payments or reimbursements due Eargo as per this Section 2.6. 
 3. Project Management. 

3.1. Project Management. Supplier is responsible, at its expense, for managing all aspects of the Services, including but not limited
to the procurement of all Components, contracting with Approved Vendors, managing all Approved Vendors, managing Supplier Parties, creating and testing First Articles for each Product, procurement, installation and maintenance of all equipment

 3.2. Use of Subcontractors. Supplier may not subcontract all or any portion of its
obligations under this Agreement or any SOW without Eargo’s prior written consent, in each instance, which consent may be withheld at Eargo’s sole and absolute discretion. In any event, Supplier is not permitted to and will not subcontract
all of its obligations under this Agreement under any circumstances unless Eargo specifically and unequivocally consents to that in advance and in writing, solely under circumstances involving a sale of all or substantially all of the business or
assets of Supplier or the liquidation of Supplier. Notwithstanding Eargo’s consent to Supplier’s engagement of any Subcontractor(s), Supplier will not be relieved of any obligations under this Agreement and will remain solely responsible
for the acts and omissions of its Subcontractors as well as the completion of the Services and delivery of the Products in accordance with this Agreement. Supplier will ensure that all Subcontractors comply with the terms of this Agreement, the
applicable SOW(s), corresponding Specifications, BOM and other referenced Appendices and documents, as well as all Policies and governing law. Any act, omission, breach, default or non-Compliance by a
Subcontractor will be deemed to be an act, omission, breach, default or non-Compliance on the part of and attributable to Supplier for which Supplier will be responsible. 

3.3. Approved Vendors. Unless otherwise expressly set forth in the applicable SOW, Supplier will use in its production of Units such
Components, and, if applicable, raw materials, of the exact type, quality, and grade specified by Eargo, to the extent Eargo chooses to so specify, and will only purchase Components, and, if applicable, raw materials, from Eargo or Approved Vendors
appearing on Appendix 3 (Approved Vendors); provided, however, that in the event Supplier cannot purchase a Component from Eargo or an Approved Vendor for any reason, Supplier will be able to purchase such Component from an
alternate vendor, subject to Eargo’s prior written approval, in each instance, [***]. Eargo makes no guarantee that certain pricing or commercial terms will be extended by such Approved Vendors to Supplier. If Eargo has a contract with an
Approved Vendor, then Eargo may require Supplier to place orders under Eargo’s contract terms, provided, however, that Supplier understands it is solely responsible for entry into an agreement with the applicable Approved Vendor.
If Supplier has a contract with an Approved Vendor, Supplier will ensure that such agreement expressly provides that Eargo is an intended third party beneficiary and is entitled to the protections of the following minimum terms and conditions
entered into by Supplier for the benefit of Eargo, including, without limitation, conformance to specifications, [***] environment regulations compliance, indemnity for infringement of intellectual property rights and
Supplier-facilitated warranty remedies. Eargo reserves the right to remove any Approved Vendor from the list in Appendix 3 to the applicable SOW, in which case, Supplier will have [***] from the date of
notice of the updated list of Approved Vendors from Eargo to wind-down its work with the former Approved Vendor(s). In addition, Supplier understands that any purchases by Supplier from an Approved Vendor
constitute a contract between Supplier and that Approved Vendor and in no event will Eargo be liable under such contract for any breach or default by the Approved Vendor or Supplier. 

3.4. Order Quantities and Lead Times. Supplier and Eargo will mutually agree upon the minimum order quantities
(“MOQs”) from Component and/or raw materials Approved Vendors every [***], which will be calculated and based upon Eargo’s most recent Forecast, unless otherwise approved in writing by Eargo in advance of purchase or delivery.
In addition, lead times for Supplier’s Component and/or raw materials Approved Vendors will be less than [***], unless otherwise approved in writing by Eargo in advance of purchase or delivery. Supplier may order any Components or raw materials
based on the applicable then-current MOQs, Forecasts and lead times. The parties acknowledge and agree that Eargo will not be responsible or liable for any Components or raw materials ordered by Supplier
beyond the lead times and MOQs specified in this Section 3.4, unless Supplier has obtained written approval in advance from Eargo, in each instance. 

  
 7 

 3.5. Inbound Quality Control. Supplier will utilize [***] to inspect the raw
materials, where applicable, and Components and Services (including any aspects of the Manufacturing Process) received from Approved Vendors to verify that all of the foregoing are in Compliance. In addition, Supplier will implement a dock to stock
program, whereby such Components and/or raw materials will be delivered directly to Supplier’s point of use. If Supplier discovers that any raw material, Component, Services or Manufacturing Process is not in Compliance, Supplier will
immediately, at its sole cost and expense, replace the non-conforming element, item or service with an element, item or service of the same nature that is in Compliance. Supplier will not use non-conforming Components in any Prototype, First Article or Products. In addition, and without limiting the foregoing, prior to manufacturing any Product(s) for Eargo, the parties will develop and publish a
mutually agreed upon quality plan (the “Quality Plan”). Supplier will adhere to all aspects of the Quality Plan and the Quality Plan will be reviewed by the parties on a [***] basis. 

3.6. Management of Supplier Parties and Approved Vendors. Supplier acknowledges and agrees that it is responsible for identifying,
qualifying, negotiating with and contracting with all Approved Vendors and Subcontractors, at no additional charge to Eargo, to ensure timely, compliant, high-quality Services, Components, Products and
Manufacturing Processes and represent Eargo’s interests. Pursuant to Section 6.6 (Contingency Plan), Supplier will define contingencies for emergency backup Subcontractors and Approved Vendors in the event that any Subcontractors and/or
Approved Vendors engaged by Supplier should fail or be unable or unwilling to perform. Supplier will provide Eargo with a backup contingency plan within [***] from the Effective Date of this Agreement. 

3.7. Eargo Equipment. If Eargo consigns certain equipment and/or fixtures to Supplier, Supplier will: (a) use the equipment per
Eargo’s equipment specifications (“Equipment Specifications”), and solely for the purposes of manufacturing Products, including any Prototypes, or pre-production Units; (b) return
the equipment to Eargo upon request in the same condition as delivered by Eargo (reasonable wear and tear excepted); (c) clearly identify all Eargo equipment by an appropriate tag; and (d) be solely responsible [***] in the use and protection
of the equipment, including routine preventive maintenance, and all repairs or replacements to or for such Eargo-consigned equipment in connection with Supplier’s or the Supplier Parties’ [***].
Without limiting the foregoing, [***]. 
 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. 

  
 10 

 5. Engineering Change Order (ECO). 

5.1. Adherence to Specifications and Approved Vendor List. Unless agreed to in advance in an Approved ECO by Eargo, Supplier will
purchase Components listed on the BOM and only through or from Eargo or Approved Vendors appearing on Appendix 3 (Approved Vendors) and perform the Services and create the Product(s) in accordance with the applicable Specifications. 

5.2. ECO Submission. Eargo will be entitled to propose additions, deletions, amendments, or other modifications or changes to any
Statement of Work, functional requirements, Specifications, BOM, Manufacturing Process, or any other aspect of the Services, Products or Components, or request that Supplier incorporate any engineering, project management or other changes relating
to the Services, Products or Components, including, without limitation, any change or modification to the materials or processes for any Services, Products or Components, (collectively, “Changes”) at any time during the Term by
submitting an engineering change order (“ECO”) (“Proposed ECO”) to Supplier. Supplier’s approval of the Proposed ECO, which will not be unreasonably withheld or delayed, is required for the specified ECO
Changes to become effective. If the Proposed ECO will impact the timing (including without limitation lead time for fulfillment of Purchase Orders) and/or costs related to any Services, Products or Components, Supplier will provide Eargo with a
reasonable evaluation of such Changes within [***] following receipt of a Proposed ECO, which evaluation will include [***]. In addition, Supplier will be entitled to propose Changes [***] by submitting a Proposed ECO to Eargo; provided that
Eargo will have the right to accept or reject any Proposed ECO by Supplier in its sole and absolute discretion. Eargo’s silence as to any Proposed ECO submitted by Supplier will not be deemed acceptance or approval. No Proposed ECO submitted by
Supplier will be accepted by or binding upon Eargo until Eargo specifically accepts that Proposed ECO in writing, in which case, the terms and conditions under which Eargo accepts such Proposed ECO will be final and binding upon Supplier. Each ECO
will be in the form as set forth in Exhibit C, and no modification, deletion or amendment to, or substitution of, the form of ECO as set forth in Exhibit C will be valid without Eargo’s prior
written consent. 
 5.3. ECO Submissions. Any and all proposed changes by Supplier to Products or Components, whether material or
immaterial, including those that affect the form, fit, or function of the Product or Component must be submitted as an ECO. Except as expressly set forth in Section 5.5 below, no Change may be made unless and until documented in an ECO,
submitted as a Proposed ECO, and approved in advance by Eargo (if submitted by Supplier) or by Supplier (if submitted by Eargo) (the “Approved ECO”). No approved Change will be effective prior to the date specified in the Approved
ECO. In addition to and not in lieu or limitation of any other remedies Eargo may have hereunder, Supplier will indemnify Eargo for any Changes undertaken by Supplier not in conformance with this Section 5. Any properly executed Approved ECO is
subject to the terms of this Agreement, except to the extent, if any, otherwise expressly set forth in such Approved ECO. Approved ECOs do not constitute amendments to the terms and conditions of this Agreement. 

  
 11 

 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.

 8. Orders. 

8.1. Order Placement. Eargo, its Affiliate(s), and any Approved Buyer(s) may purchase Products, Components and Services from Supplier
pursuant to Purchase Orders referencing this Agreement or the applicable SOW, and, where applicable as to Services that are not incidental to the production of the Products, pursuant to SOWs executed by Eargo referencing this Agreement. Eargo, its
Affiliate(s), and Approved Buyer(s), as applicable, will issue Purchase Orders on a [***] basis for the upcoming [***], pursuant to the Forecasts provided to Supplier. Supplier will accept and timely fulfill all Purchase Orders issued by Eargo, its
Affiliate(s), and any Approved Buyer(s) by the applicable Delivery Dates specified in the corresponding Purchase Orders. Any purchase of Units is inclusive of the relevant incidental Services at no additional cost. Units will be delivered in
accordance with the terms and conditions set forth in this Agreement, the applicable SOW, and its Appendices, including the applicable Specifications, and the corresponding Purchase Order(s). The entity that issues a Purchase Order to Supplier will
be considered “Eargo” for all purposes of that Purchase Order and this Agreement and that Purchase Order will be considered a two party agreement between Supplier and such entity. All Orders will be accepted by Supplier upon issuance.
Notwithstanding the foregoing, Eargo is not obligated to make any minimum amount of Orders (whether in dollars, quantity or otherwise) and makes no commitment to do so. 

8.2. Order Changes. Eargo, its Affiliate(s), or any Approved Buyer(s), as applicable, may, make any additions, deductions or deviations
to the quantities and delivery schedules for any shipments under any Purchase Order, at no additional charge, as follows: [***]. In addition, Eargo, its Affiliate(s), or any Approved Buyer(s), as applicable, may, without charge, redirect the
delivery of Units to alternate locations, change the method of shipping, or postpone delivery under a Purchase Order. 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. Each Approved Buyer will be
independently and solely responsible for its respective purchases of Units and Services hereunder, including any and all payment obligations and fees owed for such purchases. 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. 
 9. Shipment and Delivery. 

9.1. Delivery. Supplier will: (a) fulfill all orders under each Purchase Order and, where applicable, each SOW, within [***]
measured from [***]; and (b) deliver all Units and Services in accordance with Eargo’s requirements and by the delivery date(s) specified on the Purchase Order or SOW, as applicable, or such other date that Eargo may later specify as
permitted by this Agreement (“Delivery Date”). Supplier will deliver all Units to the delivery address(es) set forth in the applicable Purchase Order. Supplier hereby acknowledges and agrees that Eargo may, from time to time,
require Supplier to deliver all or a portion of the Units ordered under the Purchase Order to Approved Buyer(s)’ locations or other non-Eargo locations, pursuant to the applicable Purchase Order. Any
Components consisting of Software, will be provided via electronic delivery unless included with the Products or otherwise specified in the applicable Purchase Order or SOW. 

9.2. Shipping Terms. Except as otherwise set forth in the applicable SOW, Supplier will ship and deliver all Units [***] to the
delivery location designated by Eargo, its Affiliate or Approved Buyer, as applicable, in the applicable Purchase Order or SOW, on or before the applicable Delivery Date. Transfer of title and risk of loss will be as per [***]. Upon Eargo’s
request, at no additional charge to Eargo, Supplier will ship mixed and partial pallets of Units. 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. If delivery of any shipment of Units or completion of any Service is delayed, or Supplier anticipates will be
delayed, by more than [***] beyond the applicable Delivery Date, or amended Delivery Date (if amended by Eargo pursuant to Section 8.2), at no fault of Eargo, then Eargo may at any time thereafter terminate the applicable Purchase Order(s) or
SOW(s), in whole or in part, without any liability, be relieved of any existing or future payment obligations to Supplier with respect to such Purchase Order(s) or SOW(s), and receive from Supplier a complete refund of all amounts paid by Eargo in
connection with the terminated Purchase Order(s) or SOW(s). 
 9.4. Import/Export. Supplier will, at no charge, promptly forward to
Eargo any and all documents that may be reasonably required to allow Eargo to clear any and all Units, or any portion thereof, through customs, and/or obtain possession of any and all Units, or any portion thereof, at the port of entry. In addition,
Supplier will provide any assistance Eargo deems necessary in order for Eargo, its Affiliate(s) or Approved Buyer(s), as applicable, to obtain any export licenses or other official authorizations to carry out the export of the Units. 

9.5. Returns. If Eargo returns any Units under this Agreement, they will be returned to [***], Eargo’s place of business. Supplier
will be the exporter and importer of record for all returns and responsible for ensuring that such returns comply with all export and import regulations. Eargo will return the Units via the freight forwarders that are selected or pre-approved by Supplier. Title and risk of loss for returned Units transfers to Supplier as per [***]. 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. If any replacement Products provided to Eargo after rejection of the original Products is found to have any errors or defects, does not conform to the applicable functional requirements or Specifications, contains cosmetic or packaging

the parties in good faith; or (c) terminate any pending or committed Purchase Order(s) or SOW(s) with respect to such Products, without any penalty or other liability to Eargo. If Eargo elects to terminate any pending or committed Purchase
Order(s) or SOW(s), Eargo will, in addition to, and not in lieu or limitation of, any other remedies available to Eargo, be entitled to a prompt and full refund of all amounts previously paid for such rejected Products. 

11. Unit Price and Payment. 
 11.1.
Unit Price. The per unit price of each Product will not exceed the aggregate sum of the BOM Cost and Value Added in accordance with this Agreement (the “Unit Price”). Notwithstanding anything to the contrary, the Unit Price,
and any Price Quotations (as defined below) for Products, will include all Services that are incidental to the assembly, manufacturing, 

  
 19 

 
testing, packaging, labeling and delivery of the Units, Project Management Services, and all Services that involve finishing, testing, inspecting,
non-recurring engineering, minimum order quantities, and packaging fees, applicable royalties and all applicable inland taxes (excluding sales, use and similar taxes) and Eargo will not be invoiced or
responsible to pay or reimburse Supplier for any amounts related to such included Services. Supplier will directly sell the Units and Services to Eargo, its Affiliate(s) and Approved Buyer(s) at the agreed Unit Price. The parties will review the
Unit Price on a [***] basis. 
 11.1.1. Value Added. Parties will agree on the Value Added in writing through the Price Quotation
provided to Eargo by Supplier and the Value Added will not exceed the quoted amount unless formally amended in writing by the parties. Supplier will not increase the Value Added unless warranted by a formal change to Specifications, design,
Manufacturing Process, and/or BOM that has been documented under an Approved ECO. 
 11.2. Price Quotation. Eargo may request that
Supplier provide pricing for certain Units, Services, BOM Costs, Value Added, minimum order quantities or any other Unit Price components through a request for proposal or request for quotation (“RFP” or “RFQ”) or
other request methodology including, but not limited to, open book costing (collectively, “Price Quotation”). Supplier will not present Eargo with Unit Price increases unless such increases are justified by [***]. Eargo reserves the
right to further negotiate Unit Price provided via a Price Quotation and the agreed upon Unit Price will be applicable on a worldwide basis and will not increase for a [***] period from the agreed effective date for the Unit Price (“Pricing
Period”). If Eargo does not issue another Price Quotation for the subsequent Pricing Period, the [***] period following the Pricing Period (“Subsequent Pricing Period”), the current Unit Price will remain in effect and
fixed for the duration of the Term. 
 11.3. Non-recurring Engineering Fees. The
parties agree that any applicable non-recurring engineering fees, if any, will only include [***] and will not include any mark-ups, engineering, labor or development fees, unless otherwise expressly authorized in writing by Eargo. Any non-recurring engineering fees will be pre-approved in writing by Eargo, and Supplier acknowledges and agrees that once the
non-recurring engineering fee is paid for the Products, Supplier will not be entitled to any further non-recurring engineering fees, regardless of the extent Purchase
Orders are placed. 
 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 [***]

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. For
professional or engineering Services that are not included within the Unit Price and are performed under a SOW, Supplier will not invoice for any such Services until Acceptance has been achieved. The fees for the Units and, where applicable,
professional or engineering Services that are not included within the Unit Price will be as set forth on the applicable Purchase Order and correspond to the Unit Price under Appendix 5 (Unit Price) to the applicable SOW. At a minimum, each
invoice will identify: (a) this Agreement; (b) the applicable Purchase Order and, where applicable, SOW; (c) dates when each Unit was provided; (d) the taxing jurisdiction(s) in which each Unit was provided; (e) the name,

 11.8. Payment. All payments will be made in U.S. Dollars, unless otherwise
specified on the applicable Purchase Order or SOW. Subject to the terms of this Agreement, all invoices are due [***] after (a) delivery and successful Initial Inspection, as confirmed by Eargo, its Affiliate, or Approved Buyer, as applicable,
to which such invoice pertains, or (b) in the case of engineering or professional Services not included in the Unit Price for Units and that are performed under a SOW, after Supplier’s completion of the applicable Services and Acceptance
of the same by Eargo, and (c) in the case of (a) or (b), after Eargo’s receipt of an undisputed invoice. Eargo will have no obligation to pay any charges and expenses that Supplier fails to invoice to Eargo within [***] after
Acceptance of the applicable Units. In the event, Supplier purchases any Components and/or raw materials from Eargo, Supplier will pay all undisputed amounts on each invoice within [***] after Supplier’s receipt of such invoice. During the
Term, Supplier will extend a credit line of [***] to Eargo, and Eargo will provide updated financials to Supplier on a [***] basis so that the parties can review and discuss potential increases to Eargo’s credit line on a [***] basis. Supplier

transactions and payments under this Agreement. Subject to the terms of this Agreement, Supplier may charge and Eargo will pay applicable federal, national, state or local sales or use taxes or value added taxes that Supplier is legally obligated to
charge (“Sales Taxes”), provided that such Sales Taxes are stated on the original invoice that Supplier provides to Eargo and Supplier’s invoice states such Sales Taxes separately and meet the appropriate tax
requirements for a valid invoice. Eargo may provide Supplier with an exemption certificate acceptable to relevant taxing authorities, in which case, Supplier will not collect the Sales Taxes covered by such certificate. Throughout the Term, Supplier
will provide Eargo any forms, documents, or certifications as may be required for Eargo to satisfy any information reporting or withholding tax obligations with respect to any payments under this Agreement. Eargo will have no obligation to pay any
taxes or fees that are: (a) based upon Supplier’s net or gross income or gross receipts; (b) franchise taxes or other taxes based on Supplier’s corporate existence or status; (c) personal property taxes on Units; and
(d) due in whole or in part because of any failure by Supplier or its agents to file any return or information required by law, rule, or regulation. 

11.10. Invoice Disputes. Notwithstanding anything to the contrary, Eargo reserves the right to dispute any invoice within [***] of its
issuance. In the event of a good faith dispute with regard to an item appearing on any invoice, Eargo reserves the right to withhold such disputed amount while the parties attempt to resolve the dispute. Eargo’s withholding of such payment will
not constitute a breach of this Agreement, nor will it be grounds for Supplier to suspend or withhold any manufacturing, production, fulfillment or deliveries or otherwise suspend its performance or any Services hereunder. 

12. Term and Termination. 
 12.1.
Term. The term of this Agreement begins on the Effective Date and continues in effect for twelve (12) months, automatically renewing thereafter for additional twelve (12) month periods, unless sooner terminated as provided in this
Agreement (the “Term”).

 12.2. Termination for Convenience. Notwithstanding anything to the contrary, Eargo
may terminate this Agreement, any Purchase Order or any SOW at any time, for any or no reason, by giving Supplier one hundred and twenty (120) days’ written notice. Except as otherwise provided in this Agreement, Supplier may terminate
this Agreement, at any time, for any or no reason, by giving Eargo at least twelve (12) months’ written notice. Upon any termination for any or no reason by either party, Supplier will [***] of all amounts paid in advance for Units or
Services not yet delivered or performed by Supplier or not fully delivered or performed by Supplier in accordance with this Agreement. 

12.3. Termination for Cause. Either party may terminate this Agreement if the other party fails to cure any material breach of this
Agreement within thirty (30) days after receipt of written notice of such breach. In addition, in particular, Eargo reserves the right to terminate this Agreement for cause immediately upon written notice to Supplier in the event of:

caused by any act, omission, default or breach by Supplier or any Supplier Parties, (d) any Epidemic Failure pursuant to Section 17.3 below, (e) where permitted, any Force Majeure Event (as defined below) affecting Supplier pursuant
to Section 25.5.3 below, (f) any unauthorized distribution of the Products, or (g) any unauthorized use of the Marks. 

12.4. No Suspension. Whether or not any disabling device or capability is listed in the applicable SOW or Specifications, Supplier
agrees that in no event will it utilize or activate the same or otherwise attempt to avail itself of any self-help remedies without first obtaining a final judgment issued by a court of competent jurisdiction.
In addition, Supplier is not permitted to and will not suspend performance or suspend or withhold any deliveries during the period of any dispute between the parties or otherwise. 

12.5. Effect of Termination. Upon the expiration or any termination of this Agreement, Supplier will: (a) perform the Transition
Services, (b) return materials, information and resources made available to Supplier as required by this Agreement, (c) if requested by Eargo, fulfill all then-outstanding unfulfilled Purchase Orders
(except to the extent the same are canceled by Eargo as provided herein), (d) then cease any and all use of Eargo Property and manufacturing or sale of the Units, and (e) once all outstanding Purchase Orders (unless the same have been canceled
by Eargo as provided herein) are fulfilled, cease all use of Eargo Property. Additionally, upon the expiration or any termination of this Agreement, Eargo will have the option to purchase from Supplier any Components or Excess inventory at the
lesser of the Unit Price or the fair market value of such Components or Excess Inventory. Any termination of a Purchase Order or SOW will not result in termination of any other Purchase Orders(s), SOW(s) or this Agreement. Any termination of this
Agreement, however, will result in termination of all SOW(s) and Purchase Order(s) then un-fulfilled unless Eargo elects otherwise pursuant to an amendment to this Agreement prior to the effective date of such
termination as to the handling of then-pending Purchase Orders. 
 12.6. Transition. Unless
otherwise instructed by Eargo, upon expiration or termination of this Agreement and/or any SOW(s), Supplier will furnish any and all Prototypes, First Articles, and Products, all associated documentation pertaining to the same, and Reports, to Eargo
in the format required by Eargo, regardless of the state of completion within [***] of expiration or 

  
 23 

 
termination of this Agreement. Additionally, commencing from the expiration date of this Agreement or the termination date of this Agreement, or any SOW or Purchase Order, as applicable, if
requested by Eargo and for a period designated by Eargo (the “Transition Period”), Eargo may continue to order Units and Services. During the Transition Period [***], Supplier will also make available to Eargo such other services as
mutually agreed to by the parties, including services consisting of the transitioning of the manufacturing of Products to another manufacturing source and services that facilitate Eargo obtaining from another vendor substitute units and services
(collectively, “Transition Services”). Supplier will [***] with Eargo, its Affiliate(s) and their respective Representatives and agents in the performance of the Transition Services. If Eargo terminates this Agreement pursuant to
Section 12.3 above then Supplier will perform the Transition Services at no cost to Eargo and Supplier will not invoice or attempt to collect from Eargo fees or other amounts associated with the performance of such Transition Services.

Confidential Information, Eargo Data, Products, Enhancements, Feedback, Systems, Reports, Specifications, Approved Buyer list(s), Approved Vendor list(s), Prototypes, First Articles and Approved First Articles, and any materials or resources,
provided by Eargo to Supplier or otherwise accessed by Supplier in connection with this Agreement (collectively, “Eargo Property”). 

13.2. IPR Assignment. Supplier will not (and will not permit any Subcontractor) to improve, enhance, or modify any Products
(collectively, “Enhancements”) without Eargo’s prior written consent in each instance and without meeting Compliance and adhering to the applicable Specifications. In any event, (a) if Supplier (or any Subcontractor)
develops any Enhancements, and (b) as to all Feedback, Supplier hereby irrevocably transfers and assigns to Eargo and its Affiliate(s), successors and assigns, without further compensation or any attribution (and Eargo owns all right, title and
interest in) all Intellectual Property Rights in and to Enhancements, Products, and Feedback. If Supplier has any rights to the Enhancements, Products, or Feedback that cannot be assigned to Eargo, then Supplier hereby unconditionally and
irrevocably assigns the enforcement of any and all IPR to Eargo and grants Eargo, its Affiliate(s), Approved Buyer(s), and all of their respective subcontractors, agents and assignees, under all Intellectual Property Rights,

  
 24 

 
an exclusive, irrevocable, perpetual, universal, fully paid up, royalty-free license (with the right to sublicense through multiple levels of
sublicensees), to make, sell, lease, use, execute, reproduce, modify, adapt, display, perform, distribute, make derivative works of, export, disclose, market, promote, and otherwise disseminate or transfer, for any purpose whatsoever, and via any
means or methods now known or hereafter developed, any and all rights in and to the Enhancements, Products, and Feedback. Additionally, Supplier irrevocably and unconditionally grants Eargo the power and interest to act as Supplier’s attorney-in-fact to execute any and all documents necessary to effectuate or perfect the assignments by Supplier and other rights of Eargo under this Agreement. Supplier, on
behalf of itself and the Supplier Parties, will not assert, and otherwise waives, any and all “moral rights” or equivalent rights in and to the Enhancements, Products, and Feedback and hereby assigns to Eargo all such rights to the fullest
extent permitted by law. 
 13.3. Non-Assertion. Supplier agrees not to sue upon or
otherwise assert in any proceeding against Eargo or any of its Affiliate(s), Approved Buyer(s), subcontractors, successors, assigns, officers, directors or employees, any Intellectual Property Rights relating to any Eargo Property. Supplier further
acknowledges and agrees that it will not, and it will not authorize any employee, independent contractor or third party to, file or register for any patent, copyright, trademark, trade dress or service mark protection in any country with respect to
any Product or Component, without Eargo’s [***] in each instance, provided, however, that in no event will Supplier attempt or authorize any employee, independent contractor or third party to, file or register for any patent,
copyright, trademark, trade dress or service mark protection in any country with respect to any [***] Property. Notwithstanding anything to the contrary contained in this Agreement, the covenants contained in this Section 13 will survive the
expiration or termination of this Agreement for any or no reason. 
 13.4. Eargo Marks. Supplier agrees that it will not use
Eargo’s name, logo or trademarks or that of any of its Affiliate(s) or pertaining to any of its Products (collectively, “Marks”) except on the Products in accordance with: (a) Eargo’s
then-current branding and trademark usage guidelines, (b) Eargo’s prior approval (which may be provided in the applicable Specifications with standards against which use of the Marks must comply),
and (c) any other requirements or approvals governing use of the Marks that Eargo may furnish under the applicable SOW, which may be given or withheld in Eargo’s sole and absolute discretion. Eargo may require that Supplier manufacture
Prototypes, First Articles, and Products that bear Eargo’s Marks or other branding, as set out in the Specifications or as otherwise directed by Eargo. Supplier (and the Approved Vendors) will not manufacture any Products that contain or bear
any Marks or other branding (or alterations to any Marks or branding) that was not officially pre-approved by Eargo, in each instance, as part of the 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. All approved uses of the Marks will inure to the benefit of Eargo and its Affiliate(s), as applicable, and must be in accordance with
Eargo’s then-current branding and trademark usage guidelines provided or made available to Supplier. 

13.5. Feedback. Notwithstanding anything to the contrary, Eargo is free to retain, use and incorporate any and all written or oral
ideas, suggestions or recommendations provided by or on behalf of Supplier, its authorized Subcontractors, or any Approved Vendors (referred to as “Feedback”) relating to the Products, Marks, Eargo Data or Confidential Information,
without payment, attribution, or other consideration of any kind or nature to Supplier. 

  
 25 

 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. 
 15. Access and
Data Security. 
 15.1. Access to Systems. Access, if any, to Eargo’s computer, telecommunication or other information
systems (“Systems”), if any, is granted solely to facilitate the business relationship described in this Agreement, and is limited to those specific Systems, time periods, and personnel as are separately designated by Eargo in
writing from time to time. Access is subject to business control and information protection policies, standards, and guidelines as may be provided by Eargo. Use of any other Systems is expressly prohibited. Use of Systems during other time periods
or by individuals not authorized by Eargo is expressly prohibited. Without limiting 

  
 27

an information security program that meets the highest standards of best industry practice to safeguard Eargo Data. Such information security program will include, without limitation: (a) adequate physical security of all premises in which
Eargo Data will be processed or stored; (b) all reasonable precautions taken with respect to the employment of and access given to Supplier personnel, including background checks and security clearances that assign specific access privileges to
individuals; and (c) an appropriate network security program (which includes, without limitation, encryption of all sensitive or private data). Supplier agrees not to utilize any Eargo Data unless it is necessary to do so in order to fulfill an
obligation under this Agreement. Supplier also agrees that it will not sell, disclose, transfer, share or lease any Eargo Data under any circumstances. 

15.2.2. Notification of Security Breach. Supplier will notify Eargo immediately following discovery of any suspected breach or
compromise of the security, confidentiality, or integrity of any Eargo Data. Written notification provided pursuant to this paragraph will include a brief summary of the available facts, the status of Supplier’s investigation, and if known and
applicable, the potential number of persons affected by release of data relating to such person (“Affected Persons”). If applicable, upon written request from Eargo, Supplier agrees to notify the Affected Persons regarding any
security breach in a form approved in writing by Eargo. Such notices will be delivered within a reasonable time and in a manner approved by Eargo. Supplier agrees to provide at no charge to Affected Persons appropriate credit monitoring services for
at least [***]. All costs associated with any security breach including but not limited to, the costs of the notices to, and credit monitoring for, Affected Persons will be the sole responsibility of Supplier. Supplier agrees that it will not
communicate with any third party, including, but not limited to the media, vendors, consumers and Affected Persons regarding any security breach without Eargo’s specific prior written consent and approval of the content of such communication.
At Eargo’s request, Supplier will execute and abide by the terms of any agreements as may be required by applicable law or regulation. 

15.3. Returns; Eargo Confidentiality. Notwithstanding anything that may be construed to the contrary, Eargo, its Affiliate(s), and
Authorized Buyer(s) have no obligation to return to Supplier any Product, or Component thereof, which may contain any Eargo or Affiliate Confidential Information, including but not limited to hard disk drives, solid state drives and other memory
devices, in order for Supplier to perform its warranty obligations under this Agreement.

re-perform the Services and ship replacement Units all at no additional cost to Eargo, with Supplier being solely responsible for any and all shipping costs, including full freight costs, in both directions
for any such replacement Units. 
 16.3.2. Product Warranty Remedies. Eargo will submit any and all claims for a breach of warranty

 31 

 16.3.3. Remedial Performance Issues. If Supplier fails to repair or replace Defective
Products within [***] after Supplier’s receipt of the applicable Defective Products, or with respect to Services, within [***] after Eargo informs Supplier that the applicable Service does not conform to the warranties in Section 16, Eargo
may, at its sole option, (a) extend the correction period; or (b) obtain a full refund of all fees paid to Supplier for the defective Product and/or Service and reimbursement for any other Product and/or property that Eargo is unable to

Epidemic Failures. 
 17.1. Epidemic Failure. “Epidemic Failure” means the occurrence of Defective Products,
Component defects, or other failures (whether or not resulting in breach of any warranties of Section 16) that: (a) are experienced by more than [***] of the identifiable subclass of the Products or of the Units of any given Product or
Component in substantially the same manner, whether occurring in whole or in part during or after the Warranty Period; or (b) any governmental agency or court of competent jurisdiction finds that any Product or Component contains a safety
hazard or other condition that requires or would make advisable a recall of such Product or Component. Supplier will be responsible for any and all [***] costs and expenses that Eargo, its Affiliate(s), and their respective subcontractors, incur
related to any Epidemic Failure that is the result of Supplier or the Supplier Parties failing to manufacture the Units to the Specifications. Typical costs for which Supplier would be responsible include freight costs to recall Units from
Eargo’s customers, warehouses, or distribution centers, freight costs to ship failed Units back to Supplier, costs to remedy the Units including repair, rework, replacement, and testing costs, and freight costs to ship remedied Units back to
Eargo. 
 17.2. Failure Analysis. If an Epidemic Failure occurs: (a) Eargo will promptly notify Supplier upon discovery of the
Epidemic Failure; (b) Supplier and Eargo will jointly exert all [***] efforts to diagnose the problem and plan a work-around or more permanent solution; (c) Supplier will apply its ECO procedure in

if one is needed., Subject to Supplier’s obligations in Section 17.1, Eargo will [***], if any, of a “root cause” analysis and follow-up corrective actions associated with any epidemic
failure due [***]. 
 17.3. Termination for Epidemic Failure. If an Epidemic Failure occurs, Eargo may terminate any and all
applicable Purchase Order(s) or SOW(s) upon notice to Supplier, in whole or in part, without any liability, and receive from Supplier a complete refund of all amounts paid by Eargo in connection with the terminated Purchase Order(s) or SOW(s) and be
relieved of any and all payment obligations to Supplier with respect to such Purchase Order(s) or SOW(s). 

  
 32 

 18. Disclaimer. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES ANY WARRANTIES,
EITHER EXPRESS OR IMPLIED, AND EACH PARTY EXPRESSLY DISCLAIMS ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 
 19.
Indemnification. 
 19.1. Indemnification by Supplier. Supplier covenants and agrees to indemnify, defend and hold harmless
Eargo, its Affiliate(s), Approved Buyer(s), and their respective agents, contractors, officers, directors, employees and Representatives (including any combination of the Eargo, its Affiliate(s), Approved Buyer(s) or their respective agents,
contractors, officers, directors, employees and Representatives) (collectively, the “Indemnified Parties”) from and against any and all claims, allegations, losses, damages, settlements, governmental fines and penalties, and all
other liabilities, including attorneys’ and other professional fees and court costs, and all costs and expenses, arising out of or related to: (a) the Units, or any portion thereof, on their own or in combination with any other goods and
services, infringe any rights or IPR of a third party (collectively, “Third Party IPR”) where such Third Party IPR relates to Supplier’s Manufacturing Process, or manufacturing, packaging, testing, or other Services provided
under this Agreement, excluding Product design and materials or equipment consigned to Supplier by Eargo; (b) personal injury or property damage resulting, directly or indirectly from the Units or Services (including any Hazard), the
performance of Supplier’s obligations hereunder, or the fault or negligence of Supplier or the Supplier Parties; (c) negligent, willful or reckless acts or omissions, dishonesty or fraud of or by Supplier or any Supplier Parties;
(d) a breach or alleged breach by Supplier or any Supplier Parties of any provision or clause (e.g., Supplier or Supplier Parties act in contravention of any clause or perform acts contrary to the terms specified in this Agreement) of
this Agreement; (e) any claim or cause of action anywhere in the world asserted against Eargo or any of the Indemnified Parties alleging or in connection with alleged defects in the assembly or manufacturing of the Product(s); or
(f) violations of law in the manufacture of the Products; (each a “Claim” and collectively, “Claims”). 

19.2. Process and Remedies. Eargo will give prompt written notice of each Claim to Supplier and, subject to Supplier fulfilling all of
its obligations under this Section 19, Eargo will permit Supplier to control the defense of the Claim, provided that: (a) Supplier’s use of counsel of its own choosing has been
pre-approved by Eargo, such approval not to be unreasonably withheld or delayed; and (b) Supplier will not enter into any settlement of any Claim that imposes any obligation on Eargo without Eargo’s
prior written consent. In that event, Eargo will not settle such Claim without Supplier’s consent if such settlement requires any payment by Supplier, provided that Supplier will not unreasonably withhold or delay its consent. Eargo may
participate in the defense of any Claims by counsel of its own choosing, at its cost and expense. Notwithstanding the foregoing, Eargo may control the defense and settlement of a Claim if there is a reasonable risk that Supplier will not be able to
cover its full obligation for the Claim or if there is a significant risk of harm to Eargo from a request for an injunction. Supplier agrees to provide information and assistance reasonably necessary to enable Eargo to defend the Claim (at
Supplier’s expense), and if Supplier defends at Eargo’s request, then Eargo will do the same (at Supplier’s expense). 

  
 33 

 
Supplier will not publicize or permit any third party to publicize any settlement of such Claim or allegation without Eargo’s prior written permission, in each instance. If Supplier can
substantiate with a preponderance of the evidence that the Claim is not fully covered by the indemnity obligations in Section 19.1 above, then the parties agree the Claim will be tolled while the parties negotiate in good faith an equitable
arrangement regarding the defense of the Claim and any settlement thereof consistent with Supplier’s obligations hereunder. 
 19.3.
Claim Mitigation. Without limiting any of Supplier’s indemnification or other obligations under Section 19, if a Product becomes, or in either party’s reasonable opinion is likely to become, the subject of a Claim, Supplier
will, at Eargo’s sole option, and Supplier’s sole expense: (a) procure for Eargo the right to continue to manufacture, use, distribute, market and sell the applicable Product as contemplated hereunder; (b) modify the Product to
eliminate any Claim which might result from its manufacture, use, distribution, marketing or sale hereunder, provided that the Product’s performance must remain at least as good as provided in the Specifications and subject to
Eargo’s approval; (c) replace the Product with equally suitable, compatible and functionally equivalent non-infringing Product subject to Eargo’s approval, at no additional charge to Eargo; or
(d) reimburse Eargo for costs of cover associated with Eargo’s engagement of any third parties to perform the obligations of Supplier that are impacted by the actual or potential Claim. 

20. Limitation of Liability.
