 Exhibit 10.4 

IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 

1. PURPOSE. The purpose of this Plan is to provide incentives to attract, retain, and motivate eligible persons whose present and
potential contributions are important to the success of the Company, and any Parents, Subsidiaries, and Affiliates that exist now or in the future, by offering them an opportunity to participate in the Company’s future performance through the
grant of Awards. Capitalized terms not defined elsewhere in the text are defined in Section 29. 
 2. SHARES SUBJECT TO THE PLAN.

 2.1. Number of Shares Available. Subject to Sections 2.6 and 22 and any other applicable provisions hereof, the total
number of Shares reserved and available for grant and issuance pursuant to this Plan as of the date of adoption of the Plan by the Board, is 2,205,000 Shares, plus (a) any reserved Shares not issued or subject to outstanding awards granted
under the Company’s 2018 Equity Incentive Plan, as amended (the “2018 Plan”) on the Effective Date (as defined below), (b) Shares that are subject to awards granted under the 2018 Plan and the Company’s 2008 Equity
Incentive Plan, as amended (collectively with the 2018 Plan, the “Prior Plans”) that cease to be subject to such awards by forfeiture or otherwise after the Effective Date, (c) Shares issued under the Prior Plans before
or after the Effective Date pursuant to the exercise of stock options that are, after the Effective Date, forfeited, (d) Shares issued under the Prior Plans that are repurchased by the Company at the original purchase price or are otherwise
forfeited, and (e) Shares that are subject to stock options or other awards under the Prior Plans that are used to pay the exercise price of a stock option or withheld to satisfy the tax withholding obligations related to any award. 

2.2. Lapsed, Returned Awards. Shares subject to Awards, and Shares issued under the Plan under any Award, will again be
available for grant and issuance in connection with subsequent Awards under this Plan to the extent such Shares: (a) are subject to issuance upon exercise of an Option or SAR granted under this Plan but which cease to be subject to the Option
or SAR for any reason other than exercise of the Option or SAR, (b) are subject to Awards granted under this Plan that are forfeited or are repurchased by the Company at the original issue price, (c) are subject to Awards granted under
this Plan that otherwise terminate without such Shares being issued or (d) are surrendered pursuant to an Exchange Program. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in
reducing the number of Shares available for issuance under the Plan. Shares used to pay the exercise price of an Award or withheld to satisfy the tax withholding obligations related to an Award will become available for grant and issuance in
connection with subsequent Awards under this Plan. For the avoidance of doubt, Shares that otherwise become available for grant and issuance because of the provisions of this Section 2.2 will not include Shares subject to Awards that initially
became available because of the substitution clause in Section 22.2 hereof. 
 2.3. Minimum Share Reserve. At all times
the Company will reserve and keep available a sufficient number of Shares as will be required to satisfy the requirements of all outstanding Awards granted under this Plan. 

2.4. Automatic Share Reserve Increase. The number of Shares available for grant and issuance under the Plan will be increased on
January 1st of each of 2022 through 2031 by the lesser of (a) five percent (5%) of the total number of shares of all classes of the Company’s common stock issued and outstanding on each
December 31st immediately prior to the date of increase (rounded down to the nearest whole share) and (b) such number of Shares determined by the Board. 

  
 1 













 2.5. ISO Limitation. No more than 6,615,000 Shares will be issued pursuant to
the exercise of ISOs granted under the Plan. 
 2.6. Adjustment of Shares. If the number or class of outstanding Shares is
changed by a stock dividend, extraordinary dividend or distribution (whether in cash, shares, or other property, other than a regular cash dividend), recapitalization, stock split, reverse stock split, subdivision, combination, consolidation,
reclassification, spin-off, or similar change in the capital structure of the Company, without consideration, then (a) the number and class of Shares reserved for issuance and future grant under the Plan
set forth in Section 2.1, including Shares reserved under sub-clauses (a)-(e) of Section 2.1, (b) the Exercise Prices of and number and class of Shares subject to outstanding Options and SARs,
(c) the number and class of Shares subject to other outstanding Awards and (d) the maximum number and class of Shares that may be issued as ISOs set forth in Section 2.5, will be proportionately adjusted, subject to any required
action by the Board or the stockholders of the Company and in compliance with applicable securities or other laws, provided that fractions of a Share will not be issued. 

If, by reason of an adjustment pursuant to this Section 2.6, a Participant’s Award Agreement or other agreement related to any
Award, or the Shares subject to such Award, covers additional or different shares of stock or securities, then such additional or different shares, and the Award Agreement or such other agreement in respect thereof, will be subject to all of the
terms, conditions, and restrictions which were applicable to the Award or the Shares subject to such Award prior to such adjustment. 
 3.
ELIGIBILITY. ISOs may be granted only to Employees. All other Awards may be granted to Employees, Consultants, Directors, and Non-Employee Directors, provided that such Consultants, Directors,
and Non-Employee Directors render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction. 

4. ADMINISTRATION. 

4.1. Committee Composition; Authority. This Plan will be administered by the Committee or by the Board acting as the Committee.
Subject to the general purposes, terms, and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan, except, however, the Board will establish the terms for the grant of an
Award to Non-Employee Directors. The Committee will have the authority to: 
 (a) construe and
interpret this Plan, any Award Agreement, and any other agreement or document executed pursuant to this Plan; 
 (b) prescribe, amend, and
rescind rules and regulations relating to this Plan or any Award; 
 (c) select persons to receive Awards; 

(d) determine the form and terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the Exercise Price, the time or times when Awards may vest and be exercised (which may be based on performance criteria) or settled, any vesting acceleration or waiver of forfeiture restrictions, the
method to satisfy tax withholding obligations or any other tax liability legally due, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Committee will determine; 

  
 2 













 (e) determine the number of Shares or other consideration subject to Awards; 

(f) determine the Fair Market Value in good faith and interpret the applicable provisions of this Plan and the definition of Fair Market Value
in connection with circumstances that impact the Fair Market Value, if necessary; 
 (g) determine whether Awards will be granted singly, in
combination with, in tandem with, in replacement of, or as alternatives to, other Awards under this Plan or any other incentive or compensation plan of the Company or any Parent, Subsidiary, or Affiliate; 

(h) grant waivers of Plan or Award conditions; 

(i) determine the vesting, exercisability, and payment of Awards; 

(j) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement; 

(k) determine whether an Award has been vested and/or earned; 

(l) determine the terms and conditions of any, and to institute any Exchange Program; 

(m) reduce, waive, or modify any criteria with respect to Performance Factors; 

(n) adjust Performance Factors to take into account changes in law and accounting or tax rules as the Committee deems necessary or appropriate
to reflect the impact of extraordinary or unusual items, events, or circumstances to avoid windfalls or hardships; 
 (o) adopt terms and
conditions, rules, and/or procedures (including the adoption of any subplan under this Plan) relating to the operation and administration of the Plan to accommodate requirements of local law and procedures outside of the United States or to qualify
Awards for special tax treatment under laws of jurisdictions other than the United States; 
 (p) exercise discretion with respect to
Performance Awards; 
 (q) make all other determinations necessary or advisable for the administration of this Plan; and 

(r) delegate any of the foregoing to a subcommittee or to one or more executive officers pursuant to a specific delegation as permitted by
applicable law, including Section 157(c) of the Delaware General Corporation Law. 
 4.2.
Committee Interpretation and Discretion. Any determination made by the Committee with respect to any Award will be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express
term of the Plan or Award, at any later time, and such determination will be final and binding on the Company and all persons having an interest in any Award under the Plan. Any dispute regarding the interpretation of the Plan or any Award Agreement
will be submitted by the Participant or Company to the Committee for review. The resolution of such a dispute by the Committee will be final and binding on the Company and the Participant. The Committee may delegate to one or more executive officers
the authority to review and resolve disputes with respect to Awards held by Participants who are not Insiders, and such resolution will be final and binding on the Company and the Participant. 

  
 3 













 4.3. Section 16 of the Exchange Act. Awards granted to Participants who are
subject to Section 16 of the Exchange Act must be approved by two or more “non-employee directors” (as defined in the regulations promulgated under Section 16 of the Exchange Act). 

4.4. Documentation. The Award Agreement for a given Award, the Plan, and any other documents may be delivered to, and accepted
by, a Participant or any other person in any manner (including electronic distribution or posting) that meets applicable legal requirements. 

4.5. Foreign Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws and
practices in other countries in which the Company, its Subsidiaries, and Affiliates operate or have Employees or other individuals eligible for Awards, the Committee, in its sole discretion, will have the power and authority to: (a) determine
which Subsidiaries and Affiliates will be covered by the Plan; (b) determine which individuals outside the United States are eligible to participate in the Plan, which may include individuals who provide services to the Company, Subsidiary or
Affiliate under an agreement with a foreign nation or agency; (c) modify the terms and conditions of any Award granted to individuals outside the United States or foreign nationals to comply with applicable foreign laws, policies, customs, and
practices; (d) establish subplans and modify exercise procedures, vesting conditions, and other terms and procedures to the extent the Committee determines such actions to be necessary or advisable (and such subplans and/or modifications will
be attached to this Plan as appendices, if necessary); and (e) take any action, before or after an Award is made, that the Committee determines to be necessary or advisable to obtain approval or comply with any local governmental
regulatory exemptions or approvals, provided, however, that no action taken under this Section 4.5 will increase the Share limitations contained in Section 2.1 hereof. Notwithstanding the foregoing, the Committee may not take any actions
hereunder, and no Awards will be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law. 

5. OPTIONS. An Option is the right but not the obligation to purchase a Share, subject to certain conditions, if applicable. The
Committee may grant Options to eligible Employees, Consultants, and Directors and will determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options
(“NSOs”), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may vest and be exercised, and all other terms and conditions of the Option, subject to the following
terms of this section. 
 5.1. Option Grant. Each Option granted under this Plan will identify the Option as an ISO or an NSO.
An Option may be, but need not be, awarded upon satisfaction of such Performance Factors during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the Option is being earned upon the
satisfaction of Performance Factors, then the Committee will: (a) determine the nature, length, and starting date of any Performance Period for each Option; and (b) select from among the Performance Factors to be used to measure the
performance, if any. Performance Periods may overlap and Participants may participate simultaneously with respect to Options that are subject to different performance goals and other criteria. 

5.2. Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such
Option, or a specified future date. The Award Agreement will be delivered to the Participant within a reasonable time after the granting of the Option. 

5.3. Exercise Period. Options may be vested and exercisable within the times or upon the conditions as set forth in the Award
Agreement governing such Option, provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted and provided further that no ISO granted to a person who, at the time the
ISO is granted, directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or 

  
 4 













 
of any Parent or Subsidiary (“Ten Percent Stockholder”) will be exercisable after the expiration of five (5) years from the date the ISO is granted. The Committee
also may provide for Options to become exercisable at one time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee determines. 

5.4. Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted, provided
that: (a) the Exercise Price of an Option will be not less than one hundred percent (100%) of the Fair Market Value of the Shares on the date of grant, and (b) the Exercise Price of any ISO granted to a Ten Percent Stockholder will not be
less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased may be made in accordance with Section 12 and the Award Agreement and in accordance with any procedures
established by the Company. 
 5.5. Method of Exercise. Any Option granted hereunder will be vested and exercisable according
to the terms of the Plan and at such times and under such conditions as determined by the Committee and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. An Option will be deemed exercised when the Company
receives: (a) notice of exercise (in such form as the Committee may specify from time to time) from the person entitled to exercise the Option (and/or via electronic execution through the authorized third-party administrator), and (b) full
payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration and method of payment authorized by the Committee and permitted by the Award Agreement
and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 2.6 of the Plan. Exercising an Option in any manner will decrease
the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 

5.6. Termination of Service. If the Participant’s Service terminates for any reason except for Cause or the
Participant’s death or Disability, then the Participant may exercise such Participant’s Options only to the extent that such Options would have been exercisable by the Participant on the date Participant’s Service terminates no later
than three (3) months after the date Participant’s Service terminates (or such shorter or longer time period as may be determined by the Committee, with any exercise beyond three (3) months after the date Participant’s employment
terminates deemed to be the exercise of an NSO), but in any event no later than the expiration date of the Options. 
 (a) Death. If
the Participant’s Service terminates because of the Participant’s death (or the Participant dies within three (3) months after Participant’s Service terminates other than for Cause or because of the Participant’s
Disability), then the Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the date Participant’s Service terminates and must be exercised by the Participant’s
legal representative, or authorized assignee, no later than twelve (12) months after the date Participant’s Service terminates (or such shorter or longer time period as may be determined by the Committee), but in any event no later than
the expiration date of the Options. 
 (b) Disability. If the Participant’s Service terminates because of the Participant’s
Disability, then the Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the date Participant’s Service terminates and must be exercised by the Participant (or the
Participant’s legal representative or authorized assignee) no later than twelve (12) 

  
 5 













 
months after the date Participant’s Service terminates (or such shorter time period not less than six (6) months or longer time period as may be determined by the Committee, with any
exercise beyond (a) three (3) months after the date Participant’s employment terminates when the termination of Service is for a Disability that is not a “permanent and total disability” as defined in Section 22(e)(3) of the
Code or (b) twelve (12) months after the date Participant’s employment terminates when the termination of Service is for a Disability that is a “permanent and total disability” as defined in Section 22(e)(3) of the Code,
deemed to be exercise of an NSO), but in any event no later than the expiration date of the Options. 
 (c) Cause. Unless otherwise
determined by the Committee, if the Participant’s Service terminates for Cause, then Participant’s Options (whether or not vested) will expire on the date of termination of Participant’s Service if the Committee has reasonably
determined in good faith that such cessation of Services has resulted in connection with an act or failure to act constituting Cause (or such Participant’s Services could have been terminated for Cause (without regard to the lapsing of any
required notice or cure periods in connection therewith) at the time such Participant terminated Service), or at such later time and on such conditions as are determined by the Committee, but in any event no later than the expiration date of the
Options. Unless otherwise provided in an employment agreement, Award Agreement, or other applicable agreement, Cause will have the meaning set forth in the Plan. 

5.7. Limitations on ISOs. With respect to Awards granted as ISOs, to the extent that the aggregate Fair Market Value of the
Shares with respect to which such ISOs are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be
treated as NSOs. For purposes of this Section 5.7, ISOs will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.
In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective date of such amendment. 
 5.8. Modification,
Extension or Renewal. The Committee may modify, extend, or renew outstanding Options and authorize the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant,
impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO that is modified, extended, renewed, or otherwise altered will be treated in accordance with Section 424(h) of the Code. Subject to
Section 19 of this Plan, by written notice to affected Participants, the Committee may reduce the Exercise Price of outstanding Options without the consent of such Participants, provided, however, that the Exercise Price may not be reduced
below the Fair Market Value on the date the action is taken to reduce the Exercise Price. 
 5.9. No Disqualification.
Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be interpreted, amended, or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under
Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO under Section 422 of the Code. 
 6.
RESTRICTED STOCK UNITS. A Restricted Stock Unit (“RSU”) is an award to an eligible Employee, Consultant, or Director covering a number of Shares that may be settled by issuance of those Shares (which may consist
of Restricted Stock) or in cash. All RSUs will be made pursuant to an Award Agreement. 
 6.1. Terms of RSUs. The Committee
will determine the terms of an RSU including, without limitation: (a) the number of Shares subject to the RSU, (b) the time or times during which the RSU may be settled, (c) the consideration to be distributed on settlement, and
(d) the effect of the Participant’s 

  
 6 













 
termination of Service on each RSU, provided that no RSU will have a term longer than ten (10) years. An RSU may be awarded upon satisfaction of such performance goals based on Performance
Factors during any Performance Period as are set out in advance in the Participant’s Award Agreement. If the RSU is being earned upon satisfaction of Performance Factors, then the Committee will: (i) determine the nature, length, and
starting date of any Performance Period for the RSU; (ii) select from among the Performance Factors to be used to measure the performance, if any; and (iii) determine the number of Shares deemed subject to the RSU. Performance Periods may
overlap and Participants may participate simultaneously with respect to RSUs that are subject to different Performance Periods and different performance goals and other criteria. 

6.2. Form and Timing of Settlement. Payment of earned RSUs will be made as soon as practicable after the date(s) determined by
the Committee and set forth in the Award Agreement. The Committee, in its sole discretion, may settle earned RSUs in cash, Shares, or a combination of both. The Committee may also permit a Participant to defer payment under a RSU to a date or dates
after the RSU is earned, provided that the terms of the RSU and any deferral satisfy the requirements of Section 409A of the Code to the extent applicable. 

6.3. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date
Participant’s Service terminates (unless determined otherwise by the Committee). 
 7. RESTRICTED STOCK AWARDS. A Restricted Stock
Award is an offer by the Company to sell to an eligible Employee, Consultant, or Director Shares that are subject to restrictions (“Restricted Stock”). The Committee will determine to whom an offer will be made, the number of
Shares the Participant may purchase, the Purchase Price, the restrictions under which the Shares will be subject, and all other terms and conditions of the Restricted Stock Award, subject to the Plan. 

7.1. Restricted Stock Purchase Agreement. All purchases under a Restricted Stock Award
will be evidenced by an Award Agreement. Except as may otherwise be provided in an Award Agreement, a Participant accepts a Restricted Stock Award by signing and delivering to the Company an Award Agreement with full payment of the Purchase Price,
within thirty (30) days from the date the Award Agreement was delivered to the Participant. If the Participant does not accept such Award within thirty (30) days, then the offer of such Restricted Stock Award will terminate, unless the
Committee determines otherwise. 
 7.2. Purchase Price. The Purchase Price for a Restricted Stock Award
will be determined by the Committee and may be less than Fair Market Value on the date the Restricted Stock Award is granted. Payment of the Purchase Price must be made in accordance with Section 12 of the Plan, and the Award Agreement and in
accordance with any procedures established by the Company. 
 7.3. Terms of Restricted Stock Awards. Restricted Stock Awards
will be subject to such restrictions as the Committee may impose or are required by law. These restrictions may be based on completion of a specified period of Service with the Company or upon completion of Performance Factors, if any, during any
Performance Period as set out in advance in the Participant’s Award Agreement. Prior to the grant of a Restricted Stock Award, the Committee will: (a) determine the nature, length, and starting date of any Performance Period for the
Restricted Stock Award; (b) select from among the Performance Factors to be used to measure performance goals, if any; and (c) determine the number of Shares that may be awarded to the Participant. Performance Periods may overlap and a
Participant may participate simultaneously with respect to Restricted Stock Awards that are subject to different Performance Periods and having different performance goals and other criteria. 

  
 7 













 7.4. Termination of Service. Except as may be set forth in the
Participant’s Award Agreement, vesting ceases on such date Participant’s Service terminates (unless determined otherwise by the Committee). 

8. STOCK BONUS AWARDS. A Stock Bonus Award is an award to an eligible Employee, Consultant, or Director of Shares for Services to be
rendered or for past Services already rendered to the Company or any Parent, Subsidiary, or Affiliate. All Stock Bonus Awards will be made pursuant to an Award Agreement. No payment from the Participant will be required for Shares awarded pursuant
to a Stock Bonus Award. 
 8.1. Terms of Stock Bonus Awards. The Committee will determine the number of Shares to be awarded
to the Participant under a Stock Bonus Award and any restrictions thereon. These restrictions may be based upon completion of a specified period of Service with the Company or upon satisfaction of performance goals based on Performance Factors
during any Performance Period as set out in advance in the Participant’s Stock Bonus Agreement. Prior to the grant of any Stock Bonus Award the Committee will: (a) determine the nature, length, and starting date of any Performance Period
for the Stock Bonus Award; (b) select from among the Performance Factors to be used to measure performance goals; and (c) determine the number of Shares that may be awarded to the Participant. Performance Periods may overlap and a
Participant may participate simultaneously with respect to Stock Bonus Awards that are subject to different Performance Periods and different performance goals and other criteria. 

8.2. Form of Payment to Participant. Payment may be made in the form of cash, whole Shares, or a combination thereof, based on
the Fair Market Value of the Shares earned under a Stock Bonus Award on the date of payment, as determined in the sole discretion of the Committee. 

8.3. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date
Participant’s Service terminates (unless determined otherwise by the Committee). 
 9. STOCK APPRECIATION RIGHTS. A Stock
Appreciation Right (“SAR”) is an award to an eligible Employee, Consultant, or Director that may be settled in cash or Shares (which may consist of Restricted Stock) having a value equal to (a) the difference between the
Fair Market Value on the date of exercise over the Exercise Price multiplied by (b) the number of Shares with respect to which the SAR is being settled (subject to any maximum number of Shares that may be issuable as specified in an Award
Agreement). All SARs will be made pursuant to an Award Agreement. 
 9.1. Terms of SARs. The Committee will determine the
terms of each SAR including, without limitation: (a) the number of Shares subject to the SAR, (b) the Exercise Price and the time or times during which the SAR may be settled, (c) the consideration to be distributed on settlement of
the SAR, and (d) the effect of the Participant’s termination of Service on each SAR. The Exercise Price of the SAR will be determined by the Committee when the SAR is granted and may not be less than Fair Market Value of the Shares on the
date of grant. A SAR may be awarded upon satisfaction of Performance Factors, if any, during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the SAR is being earned upon the satisfaction of
Performance Factors, then the Committee will: (i) determine the nature, length, and starting date of any Performance Period for each SAR; and (ii) select from among the Performance Factors to be used to measure the performance, if any.
Performance Periods may overlap and Participants may participate simultaneously with respect to SARs that are subject to different Performance Factors and other criteria. 

9.2. Exercise Period and Expiration Date. A SAR will be exercisable within the times or upon the occurrence of events determined
by the Committee and set forth in the Award Agreement governing 

  
 8 













 
such SAR. The SAR Agreement will set forth the expiration date, provided that no SAR will be exercisable after the expiration of ten (10) years from the date the SAR is granted. The
Committee may also provide for SARs to become exercisable at one time or from time to time, periodically or otherwise (including, without limitation, upon the attainment during a Performance Period of performance goals based on Performance Factors),
in such number of Shares or percentage of the Shares subject to the SAR as the Committee determines. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on the date Participant’s Service terminates (unless
determined otherwise by the Committee). Notwithstanding the foregoing, the rules of Section 5.6 also will apply to SARs. 
 9.3.
Form of Settlement. Upon exercise of a SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying (a) the difference between the Fair Market Value of a Share on the date of exercise
over the Exercise Price, by (b) the number of Shares with respect to which the SAR is exercised. At the discretion of the Committee, the payment from the Company for the SAR exercise may be in cash, in Shares of equivalent value, or in some
combination thereof. The portion of a SAR being settled may be paid currently or on a deferred basis with such interest, if any, as the Committee determines, provided that the terms of the SAR and any deferral satisfy the requirements of
Section 409A of the Code to the extent applicable. 
 9.4. Termination of Service. Except as may be set forth in the
Participant’s Award Agreement, vesting ceases on the date Participant’s Service terminates (unless determined otherwise by the Committee). 

10. PERFORMANCE AWARDS. 

10.1. Types of Performance Awards. A Performance Award is an award to an eligible Employee, Consultant, or Director that is
based upon the attainment of performance goals, as established by the Committee, and other terms and conditions specified by the Committee, and may be settled in cash, Shares (which may consist of, without limitation, Restricted Stock), other
property, or any combination thereof. Grants of Performance Awards will be made pursuant to an Award Agreement that cites Section 10 of the Plan. 

(a) Performance Shares. The Committee may grant Awards of Performance Shares, designate the Participants to whom Performance Shares are
to be awarded, and determine the number of Performance Shares and the terms and conditions of each such Award. Performance Shares will consist of a unit valued by reference to a designated number of Shares, the value of which may be paid to the
Participant by delivery of Shares or, if set forth in the instrument evidencing the Award, of such property as the Committee will determine, including, without limitation, cash, Shares, other property, or any combination thereof, upon the attainment
of performance goals, as established by the Committee, and other terms and conditions specified by the Committee. The amount to be paid under an Award of Performance Shares may be adjusted on the basis of such further consideration as the Committee
will determine in its sole discretion. 
 (b) Performance Units. The Committee may grant Awards of Performance Units, designate the
Participants to whom Performance Units are to be awarded, and determine the number of Performance Units and the terms and conditions of each such Award. Performance Units will consist of a unit valued by reference to a designated amount of property
other than Shares, which value may be paid to the Participant by delivery of such property as the Committee will determine, including, without limitation, cash, Shares, other property, or any combination thereof, upon the attainment of performance
goals, as established by the Committee, and other terms and conditions specified by the Committee. 
 (c) Cash-Settled Performance
Awards. The Committee may also grant cash-based Performance Awards to Participants under the terms of this Plan. Such awards will be based on the attainment of performance goals using the Performance Factors within this Plan that are established
by the Committee for the relevant performance period. 

  
 9 













 10.2. Terms of Performance Awards. The Committee will determine, and each
Award Agreement will set forth, the terms of each Performance Award including, without limitation: (a) the amount of any cash bonus, (b) the number of Shares deemed subject to an award of Performance Shares, (c) the Performance
Factors and Performance Period that will determine the time and extent to which each award of Performance Shares will be settled, (d) the consideration to be distributed on settlement, and (e) the effect of the Participant’s
termination of Service on each Performance Award. In establishing Performance Factors and the Performance Period the Committee will: (i) determine the nature, length, and starting date of any Performance Period; (ii) select from among the
Performance Factors to be used; and (iii) determine the number of Shares deemed subject to the award of Performance Shares. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. Prior
to settlement the Committee will determine the extent to which Performance Awards have been earned. Performance Periods may overlap and Participants may participate simultaneously with respect to Performance Awards that are subject to different
Performance Periods and different performance goals and other criteria. 
 10.3. Termination of Service. Except as may be set
forth in the Participant’s Award Agreement, vesting ceases on the date Participant’s Service terminates (unless determined otherwise by the Committee). 

11. CASH AWARDS. A Cash Award (“Cash Award”) is an award that is denominated in, or payable to an eligible
Participant solely in, cash, as deemed by the Committee to be consistent with the purposes of the Plan. Cash Awards shall be subject to the terms, conditions, restrictions and limitations determined by the Committee, in its sole discretion, from
time to time. Awards granted pursuant to this Section 11 may be granted with value and payment contingent upon the achievement of Performance Factors. 

12. PAYMENT FOR SHARE PURCHASES. Payment from a Participant for Shares purchased pursuant to this Plan may be made in cash or by check
or, where expressly approved for the Participant by the Committee and where permitted by law (and to the extent not otherwise set forth in the applicable Award Agreement): 

(a) by cancellation of indebtedness of the Company to the Participant; 

(b) by surrender of shares of the Company held by the Participant that have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Award will be exercised or settled; 
 (c) by waiver of compensation due or accrued
to the Participant for services rendered or to be rendered to the Company or a Parent or Subsidiary; 
 (d) by consideration received by the
Company pursuant to a broker-assisted or other form of cashless exercise program implemented by the Company in connection with the Plan; 

(e) by any combination of the foregoing; or 

(f) by any other method of payment as is permitted by applicable law. 

The Committee may limit the availability of any method of payment, to the extent the Committee determines, in its discretion, such limitation
is necessary or advisable to comply with applicable law or facilitate the administration of the Plan.

 13. GRANTS TO NON-EMPLOYEE DIRECTORS. 

13.1. General. Non-Employee Directors are eligible to receive any type of Award offered
under this Plan except ISOs. Awards pursuant to this Section 13 may be automatically made pursuant to policy adopted by the Board, or made from time to time as determined in the discretion of the Board. No
Non-Employee Director may receive Awards under the Plan that, when combined with cash compensation received for service as a Non-Employee Director, exceed seven hundred
fifty thousand dollars ($750,000) in value (as described below) in any fiscal year or one million dollars ($1,000,000) in value (as described below) in the fiscal year of his or her election to the Board. The value of Awards for purposes of
complying with this maximum will be determined as follows: (a) for Options and SARs, grant date fair value will be calculated using the Company’s regular valuation methodology for determining the grant date fair value of Options for
reporting purposes, and (b) for all other Awards other than Options and SARs, grant date fair value will be determined by either (i) calculating the product of the Fair Market Value per Share on the date of grant and the aggregate number
of Shares subject to the Award, or (ii) calculating the product using an average of the Fair Market Value over a number of trading days and the aggregate number of Shares subject to the Award as determined by the Committee. Awards granted to an
individual while he or she was serving in the capacity as an Employee or while he or she was a Consultant but not a Non-Employee Director will not count for purposes of the limitations set forth in this
Section 13.1. 
 13.2. Eligibility. Awards pursuant to this Section 13 will be granted only to Non-Employee Directors. A Non-Employee Director who is elected or re-elected as a member of the Board will be eligible to receive an
Award under this Section 13. 
 13.3. Vesting, Exercisability and Settlement. Except as set forth in Section 22,
Awards will vest, become exercisable, and be settled as determined by the Board. With respect to Options and SARs, the exercise price granted to Non-Employee Directors will not be less than the Fair Market
Value of the Shares at the time that such Option or SAR is granted. 
 13.4. Election to Receive Awards in Lieu of Cash. A Non-Employee Director may elect to receive his or her annual retainer payments and/or meeting fees from the Company in the form of cash or Awards or a combination thereof, if permitted, and as determined, by the
Committee. Such Awards will be issued under the Plan. An election under this Section 13.4 will be filed with the Company on the form prescribed by the Company. 

14. WITHHOLDING TAXES. 

14.1. Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan or a tax event
occurs, the Company may require the Participant to remit to the Company, or to the Parent, Subsidiary, or Affiliate, as applicable, employing the Participant an amount sufficient to satisfy applicable U.S. federal, state, local, and
international income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items (the “Tax-Related
Items”) legally due from the Participant prior to the delivery of Shares pursuant to exercise or settlement of any Award. Whenever payments in satisfaction of Awards granted under this Plan are to be made in cash, such payment will be
net of an amount sufficient to satisfy applicable withholding obligations for Tax-Related Items. Unless otherwise determined by the Committee, the Fair Market Value of the Shares will be determined as of the
date that the taxes are required to be withheld and such Shares will be valued based on the value of the actual trade or, if there is none, the Fair Market Value of the Shares as of the previous trading day. 

14.2. Stock Withholding. The Committee, or its delegate(s), as permitted by applicable law, in its sole discretion and pursuant
to such procedures as it may specify from time to time and to limitations of local law, may require or permit a Participant to satisfy such Tax Related Items legally due from the 

  
 11 













 
Participant, in whole or in part by (without limitation) (a) paying cash, (b) having the Company withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the Tax-Related Items to be withheld, (c) delivering to the Company already-owned shares having a Fair Market Value equal to the Tax-Related Items to be withheld, or
(d) withholding from the proceeds of the sale of otherwise deliverable Shares acquired pursuant to an Award either through a voluntary sale or through a mandatory sale arranged by the Company. The Company may withhold or account for these Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum permissible statutory tax rate for the applicable tax jurisdiction, to the
extent consistent with applicable laws. 
 15. TRANSFERABILITY. Unless determined otherwise by the Committee, an Award may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution. If the Committee makes an Award transferable, including, without limitation, by instrument to an inter vivos or
testamentary trust in which the Awards are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or by domestic relations order to a Permitted Transferee, such Award will contain such additional terms and conditions as the
Committee deems appropriate. All Awards will be exercisable: (a) during the Participant’s lifetime only by the Participant or the Participant’s guardian or legal representative; (b) after the Participant’s death, by the
legal representative of the Participant’s heirs or legatees; and (c) in the case of all awards except ISOs, by a Permitted Transferee. 

16. PRIVILEGES OF STOCK OWNERSHIP; RESTRICTIONS ON SHARES. 

16.1. Voting and Dividends. No Participant will have any of the rights of a stockholder with respect to any Shares until the
Shares are issued to the Participant, except for any Dividend Equivalent Rights permitted by an applicable Award Agreement. Any Dividend Equivalent Rights will be subject to the same vesting or performance conditions as the underlying Award. In
addition, the Committee may provide that any Dividend Equivalent Rights permitted by an applicable Award Agreement will be deemed to have been reinvested in additional Shares or otherwise reinvested. After Shares are issued to the Participant, the
Participant will be a stockholder and have all the rights of a stockholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that if
such Shares are Restricted Stock, then any new, additional or different securities the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital
structure of the Company will be subject to the same restrictions as the Restricted Stock; provided, further, that the Participant will have no right to such stock dividends or stock distributions with respect to Unvested Shares, and
any such dividends or stock distributions will be accrued and paid only at such time, if any, as such Unvested Shares become vested Shares. The Committee, in its discretion, may provide in the Award Agreement evidencing any Award that the
Participant will be entitled to Dividend Equivalent Rights with respect to the payment of cash dividends on Shares underlying an Award during the period beginning on the date the Award is granted and ending, with respect to each Share subject to the
Award, on the earlier of the date on which the Award is exercised or settled or the date on which it is forfeited provided, that no Dividend Equivalent Right will be paid with respect to the Unvested Shares, and such dividends or stock
distributions will be accrued and paid only at such time, if any, as such Unvested Shares become vested Shares. Such Dividend Equivalent Rights, if any, will be credited to the Participant in the form of additional whole Shares as of the date of
payment of such cash dividends on Shares. 
 16.2. Restrictions on Shares. At the discretion of the Committee, the Company may
reserve to itself and/or its assignee(s) a right to repurchase (a “Right of Repurchase”) a portion of any or all Unvested Shares held by a Participant following such Participant’s termination of Service at any time
within ninety (90) days (or such longer or shorter time determined by the Committee) after the later of the date Participant’s Service terminates and the date the Participant purchases Shares under this Plan, for cash and/or cancellation
of purchase money indebtedness, at the Participant’s Purchase Price or Exercise Price, as the case may be. 

  
 12 













 17. CERTIFICATES. All Shares or other securities whether or not certificated, delivered
under this Plan will be subject to such stock transfer orders, legends, and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable U.S. federal, state, or foreign securities law, or any
rules, regulations, and other requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted, and any non-U.S. exchange controls or securities law
restrictions to which the Shares are subject. 
 18. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a Participant’s
Shares, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately endorsed in blank, with the Company or an agent
designated by the Company to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. Any Participant who is permitted to
execute a promissory note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of the
Participant’s obligation to the Company under the promissory note, provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in any event, the Company will
have full recourse against the Participant under the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares, the Participant will be required to execute and
deliver a written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is paid. 

19. REPRICING; EXCHANGE AND BUYOUT OF AWARDS. Without prior stockholder approval, the Committee may (a) reprice Options or SARs (and
where such repricing is a reduction in the Exercise Price of outstanding Options or SARs, the consent of the affected Participants is not required provided written notice is provided to them, notwithstanding any adverse tax consequences to them
arising from the repricing), and (b) with the consent of the respective Participants (unless not required pursuant to Section 5.9 of the Plan), pay cash or issue new Awards in exchange for the surrender and cancellation of any, or all,
outstanding Awards. 
 20. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will not be effective unless such Award is in
compliance with all applicable U.S. federal and state and foreign securities and exchange control and other laws, rules, and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which
the Shares may then be listed or quoted, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or
deliver certificates for Shares under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable and/or (b) completion of any registration or other qualification of
such Shares under any state, federal, or foreign law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance
with the registration, qualification, or listing requirements of any foreign or state securities laws, exchange control laws, stock exchange, or automated quotation system, and the Company will have no liability for any inability or failure to do
so. 
 21. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any
Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent, Subsidiary, or Affiliate or limit in any way the right of the Company or any Parent, Subsidiary, or Affiliate to terminate
Participant’s employment or other relationship at any time. 

  
 13 













 22. CORPORATE TRANSACTIONS. 

22.1.
Assumption or Replacement of Awards by Successor. In the event that the Company is subject to a Corporate Transaction, outstanding Awards acquired
under the Plan shall be subject to the agreement evidencing the Corporate Transaction, which need not treat all outstanding Awards in an identical manner. Such agreement, without the Participant’s consent, shall provide for one or more of the
following with respect to all outstanding Awards as of the effective date of such Corporate Transaction: 
 (a) The continuation of an
outstanding Award by the Company (if the Company is the successor entity). 
 (b) The assumption of an outstanding Award by the successor or
acquiring entity (if any) of such Corporate Transaction (or by its parents, if any), which assumption, will be binding on all selected Participants; provided that the exercise price and the number and nature of shares issuable upon exercise of any
such option or stock appreciation right, or any award that is subject to Section 409A of the Code, will be adjusted appropriately pursuant to Section 424(a) of the Code and/or Section 409A of the Code, as applicable. 

(c) The substitution by the successor or acquiring entity in such Corporate Transaction (or by its parents, if any) of equivalent awards with
substantially the same terms for such outstanding Awards (except that the exercise price and the number and nature of shares issuable upon exercise of any such option or stock appreciation right, or any award that is subject to Section 409A of
the Code, will be adjusted appropriately pursuant to Section 424(a) of the Code and/or Section 409A of the Code, as applicable). 

(d) The full or partial acceleration of exercisability or vesting and accelerated expiration of an outstanding Award and lapse of the
Company’s right to repurchase or re-acquire shares acquired under an Award or lapse of forfeiture rights with respect to shares acquired under an Award. 

(e) The settlement of the full value of such outstanding Award (whether or not then vested or exercisable) in cash, cash equivalents, or
securities of the successor entity (or its parent, if any) with a fair market value equal to the required amount, followed by the cancellation of such Awards; provided however, that such Award may be cancelled if such Award has no value, as
determined by the Committee, in its discretion. Subject to Section 409A of the Code, such payment may be made in installments and may be deferred until the date or dates the Award would have become exercisable or vested. Such payment may be
subject to vesting based on the Participant’s continued service, provided that the vesting schedule shall not be less favorable to the Participant than the schedule under which the Award would have become vested or exercisable. For purposes of
this Section 22.1(e), the fair market value of any security shall be determined without regard to any vesting conditions that may apply to such security. 

(f) The cancellation of outstanding Awards in exchange for no consideration. 

The Board shall have full power and authority to assign the Company’s right to repurchase or
re-acquire or forfeiture rights to such successor or acquiring corporation. In addition, in the event such successor or acquiring corporation (if any) refuses to assume, convert, replace or substitute Awards,
as provided above, pursuant to a Corporate Transaction, the Committee will notify the Participant in writing or electronically that such Participant’s Award will, if exercisable, be exercisable for a period of time determined by the Committee
in its sole discretion, and such Award will terminate upon the expiration of such period. Awards need not be treated similarly in a Corporate Transaction and treatment may vary from Award to Award and/or from Participant to Participant. 

  
 14 













 22.2. Assumption of Awards by the Company. The Company, from time to time,
also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either: (a) granting an Award under this Plan in substitution of such other
company’s award, or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award granted under this Plan. Such substitution or assumption will be permissible if the
holder of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the Company assumes an award granted by another company,
the terms and conditions of such award will remain unchanged (except that the Purchase Price or the Exercise Price, as the case may be, and the number and nature of Shares issuable upon exercise or settlement of any such Award will be
adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option in substitution rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise
Price. Substitute Awards will not reduce the number of Shares authorized for grant under the Plan or authorized for grant to a Participant in a calendar year. 

22.3. Non-Employee Directors’ Awards. Notwithstanding any provision to the contrary
herein, in the event of a Corporate Transaction, the vesting of all Awards granted to Non-Employee Directors will accelerate and such Awards will become exercisable (as applicable) in full prior to the
consummation of such event at such times and on such conditions as the Committee determines. 
 23. ADOPTION AND STOCKHOLDER APPROVAL.
This Plan will be submitted for the approval of the Company’s stockholders, consistent with applicable laws, within twelve (12) months before or after the date this Plan is adopted by the Board. 

24. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will become effective on the Effective Date and
will terminate ten (10) years from the date this Plan is adopted by the Board. This Plan and all Awards granted hereunder will be governed by and construed in accordance with the laws of the State of Delaware (excluding its conflict of laws
rules). 
 25. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate or amend this Plan in any respect, including,
without limitation, amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan, provided, however, that the Board will not, without the approval of the stockholders of the Company, amend this Plan in any manner that
requires such stockholder approval, provided further that a Participant’s Award will be governed by the version of this Plan then in effect at the time such Award was granted. No termination or amendment of the Plan will affect any
then-outstanding Award unless expressly provided by the Committee. In any event, no termination or amendment of the Plan or any outstanding Award may adversely affect any then outstanding Award without the consent of the Participant, unless such
termination or amendment is necessary to comply with applicable law, regulation, or rule. 
 26. NONEXCLUSIVITY OF THE PLAN. Neither
the adoption of this Plan by the Board, the submission of this Plan to the stockholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional
compensation arrangements as it may deem desirable, including, without limitation, the granting of stock awards and bonuses otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific
cases. 

  
 15 













 27. INSIDER TRADING POLICY. Each Participant who receives an Award will comply with any
policy adopted by the Company from time to time covering transactions in the Company’s securities by Employees, officers, and/or Directors of the Company, as well as with any applicable insider trading or market abuse laws to which the
Participant may be subject. 
 28. ALL AWARDS SUBJECT TO COMPANY CLAWBACK OR RECOUPMENT POLICY. All Awards, subject to applicable
law, will be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of Participant’s employment or other service with the Company that is applicable
to officers, Employees, Directors or other service providers of the Company, and in addition to any other remedies available under such policy and applicable law, may require the cancellation of outstanding Awards and the recoupment of any gains
realized with respect to Awards.

termination exists will be made in good faith by the Company and will be final and binding on the Participant. This definition does not in any way limit the Company’s or any Parent’s or Subsidiary’s ability to terminate a
Participant’s employment or services at any time as provided in Section 21 above. Notwithstanding the foregoing, the foregoing definition of “Cause” may, in part or in whole, be modified or replaced in each individual employment

the Company and issued and promulgated to employees in writing provides otherwise. In the case of any Employee on an approved leave of absence or a reduction in hours worked (for illustrative purposes only, a change in schedule from that of

 PERFORMANCE SHARES AGREEMENT 

IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 
 You have been
granted a Performance Shares Award (“Performance Shares Award”) by Impel NeuroPharma, Inc. (the “Company”), subject to the terms, restrictions and conditions of the Company’s 2021 Equity Incentive
Plan (the “Plan”), the Notice of Performance Shares Award (“Notice”) and this Performance Shares Agreement (this “Agreement”). 

1. Settlement. Your Performance Shares Award shall be settled in Shares and the Company’s transfer agent shall record
ownership of such Shares in your name as soon as reasonably practicable after achievement of the performance factors enumerated under the Vesting Schedule in the Notice. 

2. No Stockholder Rights. Unless and until you are recorded as the holder of such Shares on the stock records of the
Company and its transfer agent, you shall have no right to dividends or to vote Shares. 
 3.
No-Transfer. Your interest in this Performance Shares Award shall not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of by you or any person whose interest
derives from your interest. 
 4. Restrictions on Resale. By signing this Agreement, you agree not to sell any Shares acquired pursuant
to the Plan and this Agreement at a time when applicable laws, regulations or Company or underwriter trading policies prohibit exercise or sale. This restriction will apply as long as you are providing Service to the Company or a Subsidiary of the
Company. 
 5. Termination. If your Service terminates for any reason, all of your rights under the Plan, this Agreement and the
Notice in respect of this Award shall immediately terminate. In case of any dispute as to whether a termination of Service has occurred, the Committee shall have sole discretion to determine whether such termination has occurred and the effective
date of such termination. 
 6. Tax Consequences. YOU SHOULD CONSULT A TAX ADVISER BEFORE ACQUIRING THE SHARES IN THE
JURISDICTION IN WHICH YOU ARE SUBJECT TO TAX. Shares shall not be issued under this Agreement unless you make arrangements acceptable to the Company to pay any withholding taxes that may be due as a result of the acquisition or vesting of Shares.

 7. Responsibility for Taxes. Regardless of any action the Company or, if different, your employer (the
“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account and other tax-related items related to your participation
in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and
remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Performance Shares Award, including the grant of the Performance Shares Award, the issuance of the Shares subject to the Performance Shares Award, the vesting
of such Shares, the subsequent sale of such Shares and the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of the Performance Shares Award to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. You acknowledge that if you are subject to Tax-Related Items in more than one jurisdiction, the Company and/or the
Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

The Company will only recognize you as a record holder of Shares subject to the Performance Shares Award if you have paid or made, prior to
any relevant taxable or tax withholding event, as applicable, adequate arrangements satisfactory to the Company and/or the Employer to satisfy any withholding obligation the 












 
Company and/or the Employer may have for Tax-Related Items. In this regard, you authorize the Company and/or the Employer, and their respective agents, at
their discretion, to withhold all applicable Tax-Related Items from your wages or other cash compensation paid to you by the Company and/or the Employer or by withholding from proceeds of the sale of the
Shares subject to the Performance Shares Award either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf and you hereby authorize such sale pursuant to this authorization). The Committee may also authorize
one or a combination of the following methods to satisfy Tax-Related Items: (a) payment by you to the Company or the Employer of an amount equal to the Tax-Related
Items in cash, (b) having the Company withhold Shares subject to the Performance Shares Award that would otherwise be issued to you when they vest having a value equal to the Tax-Related Items to be
withheld, (c) delivering to the Company already-owned Shares having a value equal to the Tax-Related Items to be withheld, or (d) any other arrangement approved by the Company and permissible under
applicable law; in all cases, under such rules as may be established by the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable; provided,
however, that if you are a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall be a mandatory sale (unless the Committee shall establish an alternate method prior to the taxable or withholding event).
You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your participation in the Plan or the issuance of Shares
subject to this Performance Shares Award or vesting thereof that cannot be satisfied by the means previously described. 
 Depending on the
withholding method, the Company may withhold or account for Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum applicable
rate in which case you may receive a refund of any over-withheld amount in cash and will have no entitlement to the Shares subject to the Performance Shares Award that would otherwise be released when they vest. If the obligation for Tax-Related Items is satisfied by withholding in Shares that would otherwise be subject to release when they vest, for tax purposes, you are deemed to have been issued the full number of such Shares, notwithstanding
that a number of the such Shares are held back solely for the purpose of paying the Tax-Related Items. 

Finally, you acknowledge that the Company has no obligation to deliver Shares subject to the Performance Shares Award to you until you have
satisfied the obligations in connection with the Tax-Related Items as described in this Section. 
 8.
Acknowledgement. The Company and you agree that the Performance Shares Award is granted under and governed by the Notice, this Agreement and the provisions of the Plan (incorporated herein by reference). You:
(i) acknowledge receipt of a copy of the Plan and the Plan prospectus, (ii) represent that you have carefully read and are familiar with their provisions and the provisions of the Notice and this Agreement, and (iii) hereby accept the
Performance Shares Award subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. You hereby agree to accept as binding, conclusive and final all decisions or interpretations of the Committee upon
any questions relating to the Plan, the Notice and this Agreement. 
 9. Entire Agreement; Enforcement of Rights. This
Agreement, the Plan and the Notice constitute the entire agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning
the purchase of the Shares hereunder are superseded. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing and signed by the parties to this Agreement. The failure
by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 
 10. Stop Transfer
Orders. 
 (a) Stop-Transfer Notices. You agree that, in order to ensure compliance with the restrictions referred to
herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 












 (b) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as the owner or to accord the right to vote or pay dividends to any purchaser or other
transferee to whom such Shares shall have been so transferred. 
 11.
Compliance with Laws and Regulations. The issuance of Shares will be subject to and conditioned
upon compliance by the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s common stock may be
listed or quoted at the time of such issuance or transfer. The Shares issued pursuant to this Agreement shall be endorsed with appropriate legends, if any, determined by the Company. 

12. Governing Law; Severability. If one or more provisions of
this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with
its terms. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to
principles of conflicts of law. For purposes of litigating any dispute that may arise directly or indirectly from the Plan, the Notice and this Agreement, the parties hereby submit and consent to litigation in the exclusive jurisdiction of the State
of Washington and agree that any such litigation shall be conducted only in the courts of the State of Washington in King County, Washington or the federal courts of the United States for the State of Washington and no other courts. 

10. No Rights as Employee, Director or Consultant. Nothing in this Agreement shall affect in any manner whatsoever the right or
power of the Company, or a Parent, Subsidiary or Affiliate of the Company, to terminate your Service, for any reason, with or without Cause. 
 11.
Consent to Electronic Delivery of All Plan Documents and Disclosures. By acceptance of this Performance Shares Award, you consent to the electronic delivery of the Notice, this Agreement, the Plan, account statements, Plan
prospectuses required by the Securities and Exchange Commission, U.S. financial reports of the Company, and all other documents that the Company is required to deliver to its security holders (including, without limitation, annual reports and proxy
statements) or other communications or information related to the Performance Shares Award. Electronic delivery may include the delivery of a link to a Company intranet or the internet site of a third party involved in administering the Plan, the
delivery of the document via e-mail or such other delivery determined at the Company’s discretion. You acknowledge that you may receive from the Company a paper copy of any documents delivered
electronically at no cost if you contact the Company by telephone, through a postal service or electronic mail at [insert email]. You further acknowledge that you will be provided with a paper copy of any documents delivered electronically if
electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third party a paper copy of any documents delivered electronically if electronic delivery fails. You agree to participate in the
Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company. Also, you understand that your consent may be revoked or changed, including
any change in the electronic mail address to which documents are delivered (if you have provided an electronic mail address), at any time by notifying the Company of such revised or revoked consent by telephone, postal service or electronic mail at
[insert email]. Finally, you understand that you are not required to consent to electronic delivery. 












 12. Award Subject to Company Clawback or Recoupment. To the extent permitted by
applicable law, Performance Shares Award shall be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or the Committee or required by law during the term of your employment or other
Service that is applicable to you. In addition to any other remedies available under such policy, applicable law may require the cancellation of your Performance Shares Award (whether vested or unvested) and the recoupment of any gains realized with
respect to your Performance Shares Award. 
 BY ACCEPTING THE PERFORMANCE SHARES AWARD, YOU AGREE TO ALL OF THE TERMS AND CONDITIONS
DESCRIBED ABOVE AND IN THE PLAN.

 RESTRICTED STOCK AGREEMENT 

IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 

THIS RESTRICTED STOCK AGREEMENT (this “Agreement”) is made by and between Impel NeuroPharma, Inc., a Delaware
corporation (the “Company”), and the purchaser (“you”) named on the Notice of Restricted Stock Award (the “Notice”) pursuant to the Company’s 2021 Equity Incentive Plan
(the “Plan”) as of the date you have executed the Notice. Unless otherwise defined herein, the terms defined in the Plan shall have the same meanings in this Agreement. 

1. Sale of Stock. Subject to the terms and conditions of this Agreement, on the Purchase Date (as defined below) the Company
will issue and sell to you, and you agree to purchase from the Company, the number of Restricted Shares shown on the Notice at the Purchase Price per Restricted Share set forth on the Notice. The term “Restricted Shares”
refers to the purchased Restricted Shares and all securities received in replacement of or in connection with the Restricted Shares pursuant to stock dividends or splits, all securities received in replacement of the Restricted Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which you are entitled by reason of your ownership of the Restricted Shares. 

2. Time and Place of Purchase. The purchase and sale of the Restricted Shares under this Agreement shall occur at the principal
office of the Company simultaneously with the execution of this Agreement by the parties, or on such other date as the Company and you shall agree (the “Purchase Date”). On the Purchase Date, the Company will issue a stock
certificate registered in your name, or uncertificated shares designated for you in book entry form on the records of the Company’s transfer agent, representing the Restricted Shares to be purchased by you against payment of the purchase price
therefor by you by (a) check or wire transfer made payable to the Company, (b) cancellation of indebtedness of the Company to you, (c) your personal Services that the Committee has determined have already been or will be rendered to
the Company, or (d) a combination of the foregoing. 
 3. Restrictions on Resale. By signing this Agreement, you agree
not to sell any Restricted Shares acquired pursuant to the Plan and this Agreement at a time when applicable laws, regulations or Company or underwriter trading policies prohibit exercise or sale. This restriction will apply as long as you are
providing Service to the Company or a Subsidiary of the Company. 
 4. Company’s Repurchase Right for Unvested Shares.
The Company, or (subject to Section 4.4) its assignee, shall have the right (but not the obligation) to repurchase a portion of the Restricted Shares that are Unvested Shares (as defined below) at the times and on the terms and conditions set
forth in this Section (the “Repurchase Right”) if your Service terminates for any reason, or no reason, including without limitation, death, Disability (as defined in the Plan), voluntary resignation or termination by the
Company with or without Cause. 
 4.1 Termination of Service. In case of any dispute as to whether your Service has
terminated, the Committee shall have discretion to determine in good faith whether your Service has been terminated and the effective date of your termination of Service. 

4.2 Vested and Unvested Shares. Restricted Shares that are vested pursuant to the Vesting Schedule set forth in the Notice are
“Vested Shares.” Restricted Shares that are not vested pursuant to the Vesting Schedule set forth in the Notice are “Unvested Shares.” On the Date of Grant, all of the Restricted
Shares will be Unvested Shares. No fractional Restricted Shares shall be issued. No 












 
Restricted Shares will become Vested Shares after your termination of Service unless as set forth in the Vesting Schedule in the Notice of Grant. The number of the Restricted Shares that are
Vested Shares or Unvested Shares will be proportionally adjusted to reflect any stock split, reverse stock split or similar change in the capital structure of the Company as set forth in Section 2.6 of the Plan occurring after the Date of
Grant. 
 4.3 Exercise of Repurchase Right. Unless the Company provides written notice to you within 90 days from the date of
termination of your Service to the Company that the Company does not intend to exercise its Repurchase Right with respect to some or all of the Unvested Shares, the Repurchase Right shall be deemed automatically exercised by the Company as of the
90th day following such termination, provided that the Company may notify you that it is exercising its Repurchase Right as of a date prior to such 90th day. Unless you are otherwise notified by the Company pursuant to the preceding sentence that
the Company does not intend to exercise its Repurchase Right as to some or all of the Unvested Shares, execution of this Agreement by you constitutes written notice to you of the Company’s intention to exercise its Repurchase Right with respect
to all Unvested Shares to which such Repurchase Right applies at the time of your termination of Service. The Company, at its choice, may satisfy its payment obligation to you with respect to exercise of the Repurchase Right by either
(A) delivering a check to you or wiring funds in the amount of the purchase price for the Unvested Shares being repurchased, or (B) in the event you are indebted to the Company, canceling an amount of such indebtedness equal to the
purchase price for the Unvested Shares being repurchased, or (C) by a combination of (A) and (B) so that the combined payment and cancellation of indebtedness equals such purchase price. In the event of any deemed automatic exercise of the
Repurchase Right by canceling an amount of such indebtedness equal to the purchase price for the Unvested Shares being repurchased, such cancellation of indebtedness shall be deemed automatically to occur as of the date of termination of your
Service unless the Company otherwise satisfies its payment obligations. As a result of any repurchase of Unvested Shares pursuant to the Repurchase Right, the Company shall become the legal and beneficial owner of the Unvested Shares being
repurchased and shall have all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the number of Unvested Shares being repurchased by the Company, without further action by you. 

4.4 Assignment. The Repurchase Right may be assigned by the Company in whole or in part to any persons or organization. 

4.5 Additional or Exchanged Securities and Property. Subject to the provisions of Section 4.2 above, in the event of a
merger or consolidation of the Company with or into another entity, any other corporate reorganization, a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital
structure of the Company, without consideration, any securities or other property (including cash or cash equivalents) that are by reason of such transaction exchanged for, or distributed or issued with respect to, any Unvested Shares shall
immediately be subject to the Repurchase Right. Appropriate adjustments shall be made to the price per share to be paid for Unvested Shares upon the exercise of the Repurchase Right (by allocating such price among the Unvested Shares and such other
securities or property), provided that the aggregate purchase price payable for the Unvested Shares and all such other securities and property shall remain the same price that was original payable under the Repurchase Right to
repurchase such Unvested Shares. Subject to the provisions of Section 4.2 above, in the event of a merger or consolidation of the Company with or into another entity or any other corporate reorganization, the Repurchase Right may be exercised
by the Company’s successor. 
 5. Non-Transferability of Unvested Shares. In
addition to any other limitation on transfer created by applicable securities laws or any other agreement between the Company and you, you may not transfer any Unvested Shares, or any interest therein, unless consented to in writing by a duly
authorized 












 
representative of the Company. Any purported transfer is void and of no effect, and no purported transferee thereof will be recognized as a holder of the Unvested Shares for any purpose
whatsoever. Should such a transfer purport to occur, the Company may refuse to carry out the transfer on its books, set aside the transfer, or exercise any other legal or equitable remedy. In the event the Company consents to a transfer of Unvested
Shares, all transferees of Restricted Shares or any interest therein will receive and hold such Restricted Shares or interest subject to the provisions of this Agreement, including, insofar as applicable, the Repurchase Right. In the event of any
purchase by the Company hereunder where the Restricted Shares or interest are held by a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Restricted Shares or interest you for consideration equal to the
amount to be paid by the Company hereunder. In the event the Repurchase Right is deemed exercised by the Company, the Company may deem any transferee to have transferred the Restricted Shares or interest to you prior to their purchase by the
Company, and payment of the purchase price by the Company to such transferee shall be deemed to satisfy your obligation to pay such transferee for such Restricted Shares or interest, and also to satisfy the Company’s obligation to pay you for
such Restricted Shares or interest. 
 6. Acceptance of Restrictions. Purchase of the Restricted Shares shall constitute your
agreement to such restrictions and the legending of your certificates or the notation in the Company’s direct registration system for stock issuance and transfer of such restrictions and accompanying legends set forth in Section 7.1 with
respect thereto. Notwithstanding such restrictions, however, so long as you are the holder of the Restricted Shares, or any portion thereof, he or she shall be entitled to receive all dividends declared on and to vote the Restricted Shares and to
all other rights of a stockholder with respect thereto. 
 7. Stop Transfer Orders. 

7.1 Stop-Transfer Notices. You agree that, in order to ensure compliance with the restrictions referred to herein, the Company
may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

7.2 Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Restricted Shares that have
been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as the owner or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Restricted Shares shall
have been so transferred. 
 8. No Rights as Employee, Director or Consultant. You understand that your employment or
consulting relationship with the Company is for an unspecified duration, can be terminated at any time (i.e., is “at-will”), and that nothing in this Agreement changes the at-will nature of that relationship. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent, Subsidiary or Affiliate of the Company, to terminate your Service,
for any reason, with or without Cause. 
 9. Miscellaneous. 

9.1 Acknowledgement. The Company and you agree that the Restricted Shares are granted under and governed by the Notice, this

conclusive and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice and the Restricted Stock Agreement. 












 9.2 Entire Agreement; Enforcement of Rights. This Agreement, the Plan and the
Notice constitute the entire agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning the purchase of the
Restricted Shares hereunder are superseded. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing and signed by the parties to this Agreement. The failure by either
party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 
 9.3 Compliance
with Laws and Regulations. The issuance of Restricted Shares will be subject to and conditioned upon compliance by the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of
any stock exchange or automated quotation system on which the Company’s common stock may be listed or quoted at the time of such issuance or transfer. The Restricted Shares issued pursuant to this Agreement shall be endorsed with appropriate
legends, if any, determined by the Company. 
 9.4 Governing Law; Severability. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with its terms. This
Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of
conflicts of law. For purposes of litigating any dispute that may arise directly or indirectly from the Plan, the Notice and this Agreement, the parties hereby submit and consent to litigation in the exclusive jurisdiction of the State of Washington
and agree that any such litigation shall be conducted only in the courts of Washington in King County, Washington or the federal courts of the United States for the State of Washington and no other courts. 

9.5 Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties hereto and
their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 

9.6 Notices. Any notice to be given under the terms of the Plan shall be addressed to the Company in care of its principal
office, and any notice to be given to you shall be addressed to you at the address maintained by the Company for such person or at such other address as you may specify in writing to the Company. Any and all notices required or permitted to be given
to a party pursuant to the provisions of this Agreement will be in writing and will be effective and deemed to provide such party sufficient notice under this Agreement on the earliest of the following: (a) at the time of personal delivery, if
delivery is in person; (b) at the time of transmission by facsimile, addressed to the other party at its facsimile number specified herein (or hereafter modified by subsequent notice to the parties hereto), with confirmation of receipt made by
both telephone and printed confirmation sheet verifying successful transmission of the facsimile; (c) one (1) business day after deposit with an express overnight courier for United States deliveries, or two (2) business days after such
deposit for deliveries outside of the United States, with proof of delivery from the courier requested; or (d) three (3) business days after deposit in the United States mail by certified mail (return receipt requested) for United States
deliveries. All notices for delivery outside the United States will be sent by facsimile or by express courier. All notices not 












 
delivered personally or by facsimile will be sent with postage and/or other charges prepaid and properly addressed to the party to be notified at the address or facsimile number set forth below
the signature lines of this Agreement, or at such other address or facsimile number as such other party may designate by one of the indicated means of notice herein to the other parties hereto. Notices to the Company will be marked “Attention:
[title].” 
 9.7 U.S. Tax Consequences. Unless an Election (defined below) is made, upon vesting of Restricted Shares,
you will include in taxable income the difference between the fair market value of the vesting Restricted Shares, as determined on the date of their vesting, and the price paid for the Restricted Shares. This will be treated as ordinary income by
you and will be subject to withholding by the Company when required by applicable law. In the absence of an Election, the Company shall satisfy the withholding requirements as set forth in Section 10 below. If you make an Election, then you
must, prior to making the Election, pay in cash (or cash equivalent) to the Company an amount equal to the amount the Company is required to withhold for income and employment taxes. 

10. Responsibility for Taxes. Regardless of any action the Company or, if different, your employer (the
“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account and other tax-related items related to your participation
in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and
remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Shares purchased under this award, including the issuance of the Restricted Shares or vesting of such Restricted Shares, the subsequent sale of
Restricted Shares and the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of the award or any aspect of the Restricted Shares to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. You acknowledge that if you are subject to Tax-Related Items in more than one jurisdiction, the Company and/or the
Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

The Company will only recognize you as a record holder of Restricted Shares if you have paid or made, prior to any relevant taxable or tax
withholding event, as applicable, adequate arrangements satisfactory to the Company and/or the Employer to satisfy any withholding obligation the Company and/or the Employer may have for Tax-Related Items. In
this regard, you authorize the Company and/or the Employer, and their respective agents, at their discretion, to withhold all applicable Tax-Related Items from your wages or other cash compensation paid to you
by the Company and/or the Employer or by one or a combination of the following methods: (a) payment by you to the Company or the Employer of an amount equal to the Tax-Related Items in cash,
(b) having the Company withhold otherwise deliverable Restricted Shares that would otherwise be released from the Repurchase Right when they vest having a value equal to the Tax-Related Items to be
withheld, (c) delivering to the Company already-owned Shares having a value equal to the Tax-Related Items to be withheld, (d) withholding from proceeds of the sale of the Restricted Shares either
through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf and you hereby authorize such sale pursuant to this authorization), or (e) any other arrangement approved by the Company and permissible under
applicable law; in all cases, under such rules as may be established by the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable; provided,
however, that if you are a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall be a mandatory sale under (d) above (unless the Committee shall establish an alternate method prior to the taxable or
withholding event). You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your Participation in the Plan or
your purchase of Restricted Shares that cannot be satisfied by the means previously described. 












 Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum applicable rate in which case you may receive a refund of any over-withheld
amount in cash and will have no entitlement to the Restricted Shares that would otherwise be released from the Repurchase Right when they vest. If the obligation for Tax-Related Items is satisfied by
withholding in Restricted Shares that would otherwise be released from the Repurchase Right when they vest, for tax purposes, you are deemed to have been issued the full number of Restricted Shares, notwithstanding that a number of the Restricted
Shares are held back solely for the purpose of paying the Tax-Related Items. 
 Finally, you
acknowledge that the Company has no obligation to deliver Restricted Shares or proceeds from the sale of Restricted Shares to you or to release Restricted Shares from the Repurchase Right when they vest until you have satisfied the obligations in
connection with the Tax-Related Items as described in this Section. 
 11.
Section 83(b) Election. You hereby acknowledge that you have been informed that, with respect to the purchase of the Restricted Shares, an election may be filed by you with the Internal Revenue Service, within 30 days of
the purchase of the Restricted Shares, electing for United States tax purposes pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the Restricted Shares and their Fair Market Value on the
date of purchase (the “Election”). Making the Election will result in recognition of taxable income to you on the date of purchase, measured by the excess, if any, of the Fair Market Value of the Restricted Shares over the
purchase price for the Restricted Shares. Absent such an Election, taxable income will be measured and recognized by you at the time or times on which the Company’s Repurchase Right lapses. You are strongly encouraged to seek the advice of your
own tax advisors in connection with the purchase of the Restricted Shares and the advisability of filing of the Election. YOU ACKNOWLEDGE THAT IT IS SOLELY YOUR RESPONSIBILITY, AND NOT THE COMPANY’S RESPONSIBILITY, TO TIMELY FILE THE ELECTION
UNDER SECTION 83(b) OF THE CODE, EVEN IF YOU REQUEST THE COMPANY, OR ITS REPRESENTATIVE, TO MAKE THIS FILING ON YOUR BEHALF. 

12. Consent to Electronic Delivery and Acceptance of All Plan Documents and Disclosures. By acceptance of this Restricted Stock
Award, you consent to the electronic delivery of the Notice, this Agreement, the Plan, account statements, Plan prospectuses required by the Securities and Exchange Commission, U.S. financial reports of the Company, and all other documents that the
Company is required to deliver to its security holders (including, without limitation, annual reports and proxy statements) or other communications or information related to the Restricted Stock Award. Electronic delivery may include the delivery of
a link to a Company intranet or the internet site of a third party involved in administering the Plan, the delivery of the document via e-mail or such other delivery determined at the Company’s
discretion. You acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost if you contact the Company by telephone, through a postal service or electronic mail at [insert email]. You further
acknowledge that you will be provided with a paper copy of any documents delivered electronically if electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third party a paper copy of
any documents delivered electronically if electronic delivery fails. You agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party
designated by the Company. Also, you understand that your consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if you have provided an electronic mail address), at any time by
notifying the Company of such revised or revoked consent by telephone, postal service or electronic mail at [insert email]. Finally, you understand that you are not required to consent to electronic delivery. 












 13. Award Subject to Company Clawback or Recoupment. To the extent permitted
by applicable law, the Restricted Shares shall be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or the Committee or required by law during the term of your employment or other
Service that is applicable to you. In addition to any other remedies available under such policy, applicable law may require the cancellation of your Restricted Shares (whether vested or unvested) and the recoupment of any gains realized with
respect to your Restricted Shares. 
 BY ACCEPTING THIS RESTRICTED STOCK AWARD, YOU AGREE TO ALL OF THE TERMS AND CONDITIONS DESCRIBED ABOVE
AND IN THE PLAN.

 IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AWARD AGREEMENT 

Unless otherwise defined in this Restricted Stock Unit Award Agreement (this “Agreement”), any capitalized terms used
herein will have the same meaning ascribed to them in the Impel NeuroPharma, Inc. 2021 Equity Incentive Plan (the “Plan”). 

Participant has been granted Restricted Stock Units (“RSUs”) subject to the terms, restrictions, and conditions of the
Plan, the Notice of Restricted Stock Unit Award (the “Notice”), and this Agreement. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of the Notice or this Agreement, the
terms and conditions of the Plan will prevail. 
 1. Settlement. Settlement of RSUs shall be made in the same calendar year as
the applicable date of vesting under the vesting schedule set forth in the Notice; provided, however, that if a vesting date under the vesting schedule set forth in the Notice occurs in December, then settlement of any RSUs that vest in December
shall be made within 30 days of vesting. Settlement of RSUs shall be in Shares. Settlement means the delivery to Participant of the Shares vested under the RSUs. No fractional RSUs or rights for fractional Shares will be created pursuant to this
Agreement. 
 2. No Stockholder Rights. Unless and until such time as Shares are issued in settlement of vested RSUs,
Participant will have no ownership of the Shares allocated to the RSUs and will have no rights to dividends or to vote such Shares. 
 3.
Dividend Equivalents. Dividend equivalents, if any (whether in cash or Shares), will not be credited to Participant, except as permitted by the Committee. 

4. Non-Transferability of RSUs. The RSUs and any interest therein will not be sold,
assigned, transferred, pledged, hypothecated, or otherwise disposed of in any manner other than by will or by the laws of descent or distribution or court order or unless otherwise permitted by the Committee on a case-by-case basis. 
 5. Termination; Leave of Absence; Change in Status. If
Participant’s Service terminates for any reason, all unvested RSUs will be forfeited to the Company immediately, and all rights of Participant to such RSUs automatically terminate without payment of any consideration to Participant.
Participant’s Service will be considered terminated as of the date Participant is no longer providing services (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the
jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any) and will not, subject to the laws applicable to Participant’s Award, be extended by any notice period mandated under local laws (e.g.,
Service would not include a period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any). Participant
acknowledges and agrees that the Vesting Schedule may change prospectively in the event Participant’s service status changes between full- and part-time status and/or in the event Participant is on an approved leave of absence in accordance the
Company’s policies relating to work schedules and vesting of awards or as determined by the Committee. Participant acknowledges that the vesting of the Shares pursuant to this Notice and Agreement is subject to Participant’s continued
Service. In case of any dispute as to whether termination of Service has occurred, the Committee will have sole discretion to determine whether such termination of Service has occurred and the effective date of such termination (including whether
Participant may still be considered to be providing services while on an approved leave of absence). 












 6. Taxes. 

(a) Responsibility for Taxes. To the extent permitted by applicable law, Participant acknowledges that, regardless of any action taken
by the Company or, if different, a Parent, Subsidiary or Affiliate employing or retaining Participant (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on
account or other tax-related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related
Items”) is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer, if any. Participant further acknowledges that the Company and/or the Employer (i) make no
representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs, including, but not limited to, the grant, vesting or settlement of the RSUs and the
subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends, and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate
Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant is subject to Tax-Related Items in more than one
jurisdiction, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.
PARTICIPANT SHOULD CONSULT A TAX ADVISER APPROPRIATELY QUALIFIED IN THE COUNTRY OR COUNTRIES IN WHICH PARTICIPANT RESIDES OR IS SUBJECT TO TAXATION. 

(b) Withholding. Prior to any relevant taxable or tax withholding event, to the extent permitted by applicable law and as applicable,
Participant agrees to make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or the Employer, or their
respective agents, at their discretion, to satisfy any withholding obligations for Tax-Related Items by one or a combination of the following: 

 

	 	(i)	 withholding from Participant’s wages or other cash compensation paid to Participant by the Company and/or
the Employer; or 


  

	 	(ii)	 withholding from proceeds of the sale of Shares acquired upon settlement of the RSUs either through a voluntary
sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization and without further consent); 


  

	 	(iii)	 withholding Shares to be issued upon settlement of the RSUs, provided the Company only withholds the number of
Shares necessary to satisfy no more than the maximum applicable statutory withholding amounts; 


  

	 	(iv)	 Participant’s payment of a cash amount (including by check representing readily available funds or a wire
transfer); or 


  

	 	(v)	 any other arrangement approved by the Committee and permitted under applicable law; 



all under such rules as may be established by the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable; provided however, that if Participant is a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall be a mandatory sale (unless
the Committee (as constituted in accordance with Rule 16b-3 under the Exchange Act) shall establish an alternate method prior to the taxable or withholding event). 

Depending on the withholding method, the Company may withhold or account for Tax-Related Items by
considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum permissible statutory rate for Participant’s tax jurisdiction(s) in which case Participant will have no entitlement to the
equivalent amount in Shares and will receive a refund of any over-withheld amount in cash in accordance with applicable law. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for
tax purposes, Participant is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares are held back solely for the purpose of satisfying the withholding obligation for Tax-Related Items. 












 Finally, Participant agrees to pay to the Company and/or the Employer any amount of Tax-Related Items that the Company and/or the Employer may be required to withhold or account for as a result of Participant’s participation in the Plan that cannot be satisfied by the means previously
described. The Company has no obligation to deliver Shares or proceeds from the sale of Shares to Participant until Participant has satisfied the obligations in connection with the Tax-Related Items as
described in this Section. 
 7. Nature of Grant. By accepting the RSUs, Participant acknowledges, understands and agrees that:

 (a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or
terminated by the Company at any time, to the extent permitted by the Plan; 
 (b) the grant of the RSUs is exceptional, voluntary, and
occasional, and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of RSUs, even if RSUs have been granted in the past; 

(c) all decisions with respect to future RSUs or other grants, if any, will be at the sole discretion of the Company; 

(d) Participant is voluntarily participating in the Plan; 

(e) the RSUs and Participant’s participation in the Plan will not create a right to employment or be interpreted as forming or amending
an employment or service contract with the Company or the Employer and will not interfere with the ability of the Company or the Employer, as applicable, to terminate Participant’s employment or service relationship (if any); 

(f) the RSUs and the Shares subject to the RSUs, and the income and value of same, are not intended to replace any pension rights or
compensation; 
 (g) the RSUs and the Shares subject to the RSUs, and the income and value of same, are not part of normal or expected
compensation for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments,
bonuses, long-service awards, pension or retirement, or welfare benefits or similar payments; 
 (h) unless otherwise agreed with the
Company, the RSUs, and the Shares subject to the RSUs, and the income and value of same, are not granted as consideration for, or in connection with, the service Participant may provide as a director of a Parent, Subsidiary, or Affiliate; 

(i) the future value of the underlying Shares is unknown, indeterminable, and cannot be predicted with certainty; 

(j) no claim or entitlement to compensation or damages will arise from forfeiture of the RSUs resulting from Participant’s termination of
Service (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any),
and in consideration of the grant of the RSUs to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Employer, the Company, and any Parent, Subsidiary or Affiliate; waives his or her
ability, if any, to bring any such claim; and releases the Employer, the Company, and any Parent, Subsidiary, or Affiliate from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then,
by participating in the Plan, Participant will be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim; 












 (k) unless otherwise provided in the Plan or by the Company in its discretion, the RSUs and
the benefits evidenced by this Agreement do not create any entitlement to have the RSUs or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any Corporate
Transaction affecting the Shares; and 
 (l) the following provisions apply only if Participant is providing services outside the United
States: 
  

	 	(i)	 the RSUs and the Shares subject to the RSUs are not part of normal or expected compensation or salary for any
purpose; 


  

	 	(ii)	 Participant acknowledges and agrees that neither the Company, the Employer nor any Parent or Subsidiary or
Affiliate will be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the RSUs or of any amounts due to Participant pursuant to the settlement of the
RSUs or the subsequent sale of any Shares acquired upon settlement. 


 8. No Advice Regarding Grant. The
Company is not providing any tax, legal, or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant
acknowledges, understands and agrees he or she should consult with his or her own personal tax, legal, and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

9. Language. If Participant has received this Agreement or any other document related to the RSU and/or the Plan translated into a
language other than English and if the meaning of the translated version is different than the English version, the English version will control. 

10. Imposition of Other Requirements. The Company reserves the right to impose other requirements on Participant’s
participation in the Plan, on the RSUs and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to sign any additional agreements or
undertakings that may be necessary to accomplish the foregoing. 
 11. Acknowledgement. The Company and Participant agree that
the RSUs are granted under and governed by the Notice, this Agreement, and the Plan (incorporated herein by reference). Participant: (a) acknowledges receipt of a copy of the Plan and the Plan prospectus, (b) represents that Participant
has carefully read and is familiar with their provisions, and (c) hereby accepts the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. 

12. Entire Agreement; Enforcement of Rights. This Agreement, the Plan, and the Notice constitute the entire agreement and
understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments, or negotiations concerning the purchase of the Shares hereunder are superseded. No adverse
modification of or adverse amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing and signed by the parties to this Agreement (which writing and signing may be electronic). The failure by
either party to enforce any rights under this Agreement will not be construed as a waiver of any rights of such party. 












 13.
Compliance with Laws and Regulations. The issuance of Shares and the sale of Shares will be
subject to and conditioned upon compliance by the Company and Participant with all applicable state, federal, local and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which
the Company’s Shares may be listed or quoted at the time of such issuance or transfer. Participant understands that the Company is under no obligation to register or qualify the Common Stock with any state, federal, or foreign securities
commission or to seek approval or clearance from any governmental authority for the issuance or sale of the Shares. Further, Participant agrees that the Company will have unilateral authority to amend the Plan and this RSU Agreement without
Participant’s consent to the extent necessary to comply with securities or other laws applicable to issuance of Shares. Finally, the Shares issued pursuant to this RSU Agreement will be endorsed with appropriate legends, if any, determined by
the Company. 
 14. Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law,
the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (a) such provision will be excluded from this Agreement,
(b) the balance of this Agreement will be interpreted as if such provision were so excluded and (c) the balance of this Agreement will be enforceable in accordance with its terms. 

15. Governing Law and Venue. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the
parties hereto will be governed, construed, and interpreted in accordance with the laws of the State of Delaware, without giving effect to such state’s conflict of laws rules. 

Any and all disputes relating to, concerning or arising from this Option Agreement, or relating to, concerning or arising from the
relationship between the parties evidenced by the Plan or this Option Agreement, will be brought and heard exclusively in the United States District Court for the State of Washington or the Superior Court in King County, Washington. Each of the
parties hereby represents and agrees that such party is subject to the personal jurisdiction of said courts; hereby irrevocably consents to the jurisdiction of such courts in any legal or equitable proceedings related to, concerning, or arising from
such dispute, and waives, to the fullest extent permitted by law, any objection which such party may now or hereafter have that the laying of the venue of any legal or equitable proceedings related to, concerning, or arising from such dispute which
is brought in such courts is improper or that such proceedings have been brought in an inconvenient forum. 
 16. No Rights as Employee,
Director or Consultant. Nothing in this Agreement shall create a right to employment or other Service or be interpreted as forming or amending an employment, service contract or relationship with the Company and this Agreement shall
not affect in any manner whatsoever any right or power of the Company, or a Parent, Subsidiary or Affiliate, to terminate Participant’s Service, for any reason, with or without Cause. 

17. Consent to Electronic Delivery of All Plan Documents and Disclosures. By Participant’s acceptance of the Notice (whether
in writing or electronically), Participant and the Company agree that the RSUs are granted under and governed by the terms and conditions of the Plan, the Notice, and this Agreement. Participant has reviewed the Plan, the Notice, and this Agreement
in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Notice and Agreement, and fully understands all provisions of the Plan, the Notice, and this Agreement. Participant hereby agrees to accept as binding,
conclusive, and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice, and this Agreement. Participant further agrees to notify the Company upon any change in Participant’s residence
address. By acceptance of the RSUs, Participant agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company
and consents to the electronic delivery of the Notice, this Agreement, the Plan, account statements, Plan prospectuses required by the U.S. Securities and Exchange Commission, U.S. financial reports of the Company, and all other documents that the
Company is required to deliver to its security holders (including, without limitation, annual reports and proxy statements), or other communications or information related to the RSUs and current or future participation in the Plan. Electronic
delivery may include the delivery of a link to the Company intranet or the internet site of a third 












 
party involved in administering the Plan, the delivery of the document via e-mail, or such other delivery determined at the Company’s discretion.
Participant acknowledges that Participant may receive from the Company a paper copy of any documents delivered electronically at no cost if Participant contacts the Company by telephone, through a postal service, or electronic mail to Stock
Administration. Participant further acknowledges that Participant will be provided with a paper copy of any documents delivered electronically if electronic delivery fails; similarly, Participant understands that Participant must provide on request
to the Company or any designated third party a paper copy of any documents delivered electronically if electronic delivery fails. Also, Participant understands that Participant’s consent may be revoked or changed, including any change in the
electronic mail address to which documents are delivered (if Participant has provided an electronic mail address), at any time by notifying the Company of such revised or revoked consent by telephone, postal service, or electronic mail to Stock
Administration. Finally, Participant understands that Participant is not required to consent to electronic delivery if local laws prohibit such consent. 

18. Insider Trading Restrictions/Market Abuse Laws. Participant acknowledges that, depending on Participant’s country of
residence, Participant may be subject to insider trading restrictions and/or market abuse laws, which may affect Participant’s ability to, directly or indirectly, acquire or sell the Shares or rights to Shares under the Plan during such times
as Participant is considered to have “inside information” regarding the Company (as defined by the laws in Participant’s country). Any restrictions under these laws or regulations are separate from and in addition to any restrictions
that may be imposed under any applicable Company insider trading policy. Participant acknowledges that it is Participant’s responsibility to comply with any applicable restrictions and understands that Participant should consult his or her
personal legal advisor on such matters. In addition, Participant acknowledges that he or she read the Company’s Insider Trading Policy, and agrees to comply with such policy, as it may be amended from time to time, whenever Participant acquires
or disposes of the Company’s securities. 
 19. Code Section 409A. For purposes of this
Agreement, a termination of employment will be determined consistent with the rules relating to a “separation from service” as defined in Section 409A of the Internal Revenue Code and the regulations thereunder
(“Section 409A”). Notwithstanding anything else provided herein, to the extent any payments provided under this RSU Agreement in connection with Participant’s termination of employment
constitute deferred compensation subject to Section 409A, and Participant is deemed at the time of such termination of employment to be a “specified employee” under Section 409A, then such payment will not be made or commence
until the earlier of (a) the expiration of the six (6) month period measured from Participant’s separation from service to the Employer or the Company, or (b) the date of Participant’s death following such a separation from
service; provided, however, that such deferral will only be effected to the extent required to avoid adverse tax treatment to Participant including, without limitation, the additional tax for which Participant would otherwise be liable under
Section 409A(a)(1)(B) in the absence of such a deferral. To the extent any payment under this RSU Agreement may be classified as a “short-term deferral” within the meaning of Section 409A, such payment will be deemed a short-term
deferral, even if it may also qualify for an exemption from Section 409A under another provision of Section 409A. Payments pursuant to this section are intended to constitute separate payments for purposes of
Section 1.409A-2(b)(2) of the Treasury Regulations. 
 20.
Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the
Company’s securities, Participant hereby agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in
the registration), except pursuant to a transfer for no consideration in accordance with Section 4 above, without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of
the public offering; provided however that, if during the last seventeen (17) days of the restricted period the Company 












 
issues an earnings release or material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release
earnings results during the sixteen (16)-day period beginning on the last day of the restricted period, then, upon the request of the managing underwriter, to the extent required by any Financial Industry
Regulatory Authority rules, the restrictions imposed by this Section shall continue to apply until the end of the third trading day following the expiration of the fifteen (15)-day period beginning on the
issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred sixteen (216) days after the effective date of the registration statement. 

21. Award Subject to Company Clawback or Recoupment. To the extent permitted by applicable law, the RSUs will be subject to
clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of Participant’s employment or other Service that is applicable to Participant. In addition to any other
remedies available under such policy and applicable law, the Company may require the cancellation of Participant’s RSUs (whether vested or unvested) and the recoupment of any gains realized with respect to Participant’s RSUs. 

BY ACCEPTING THIS AWARD OF RSUS, PARTICIPANT AGREES TO ALL OF THE TERMS AND CONDITIONS DESCRIBED ABOVE AND IN THE PLAN.

 STOCK APPRECIATION RIGHT AWARD AGREEMENT 

IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 
 You have been
granted an award of Stock Appreciation Rights (the “SAR”) by Impel NeuroPharma, Inc. (the “Company”) under the Company’s 2021 Equity Incentive Plan (the “Plan”), subject to
the terms and conditions of the Plan, the Notice of Stock Appreciation Right Award (the “Notice of Grant”), and this Stock Appreciation Right Agreement (the “Agreement”). 

1. Grant of SAR. You have been granted a SAR for the number of Shares set forth in the Notice of Grant with the Exercise
Price set forth in the Notice of Grant. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of the Plan shall prevail. 

2. Termination Period. 

(a) General Rule. If your Service terminates for any reason except death or Disability, and other than for Cause, then this SAR will
expire at the close of business at Company headquarters on the date three months after your termination of Service (subject to the expiration detailed in Section 5 or as provided in the Plan). In no event shall this SAR be exercised later than
the Expiration Date set forth in the Notice of Grant. If your Service is terminated for Cause, this SAR will expire upon the date of such termination. The Company determines when your Service terminates for all purposes under this Agreement. 

You acknowledge and agree that the vesting schedule set forth in the Notice of Grant may change prospectively in the event that your service
status changes between full and part-time status in accordance with Company policies relating to work schedules and vesting of awards. You acknowledge that the vesting of the SARs pursuant to this Agreement is earned only by continuing Service. 

(b) Death; Disability. If you die before your Service terminates (or you die within three months of your termination of Service other
than for Cause), then this SAR will expire at the close of business at Company headquarters on the date 12 months after the date of death (subject to the expiration detailed in Section 5 or as provided in the Plan). If your Service terminates
because of your Disability, then this SAR will expire at the close of business at Company headquarters on the date 12 months after your termination date (subject to the expiration detailed in Section 5 or as provided in the Plan).
 
 (c) No Notice. You are responsible for keeping track of these exercise periods following your termination of Service for
any reason. The Company will not provide further notice of such periods. In no event shall this SAR be exercised later than the Expiration Date set forth in the Notice of Grant. 

3. Exercise of SAR. 

(a) Right to Exercise. Subject to the applicable provisions of the Plan and this Agreement, this SAR is exercisable during its term in
accordance with the Vesting Schedule set forth in the Notice of Grant and the applicable provisions of the Plan and this Agreement. In the event of your death, Disability, or other cessation of Service, the exercisability of the SAR is governed by
the applicable provisions of the Plan, the Notice of Grant and this Agreement. This SAR may not be exercised for a fraction of a Share. 

(b) Method of Exercise. This SAR is exercisable by delivery of an exercise notice in a form specified by the Company (the
“Exercise Notice”), which shall state the election to exercise the SAR, the number of Shares in respect of which the SAR is being exercised, and such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be delivered in person, by mail, via electronic mail or facsimile or by other authorized method to the Secretary of the Company or other person designated by the Company. This SAR
shall be deemed to be exercised upon receipt by the Company of a fully executed Exercise Notice and any applicable withholding of Tax-Related Items that are required to be withheld as detailed in
Section 7 below. 












 (c) No Shares shall be issued pursuant to the exercise of this SAR unless such issuance and
exercise complies with all relevant provisions of law and the requirements of any stock exchange or quotation service upon which the Shares are then listed. Assuming such compliance, for income tax purposes the exercised Shares shall be considered
transferred to you on the date the SAR is exercised with respect to such exercised Shares. 
 4.
Non-Transferability of SAR. This SAR may not be transferred in any manner other than by will or by the laws of descent or distribution or court order and may be exercised during your lifetime
only by you unless otherwise permitted by the Committee on a case-by-case basis. The terms of the Plan and this Agreement shall be binding upon your executors,
administrators, heirs, successors and assigns. 
 5. Term of SAR. This SAR shall in any event expire on the Expiration
Date set forth in the Notice of Grant, which date is ten years after the Date of Grant. You are responsible for keeping track of the Expiration Date. The Company is not obligated to provide notice of the Expiration Date and you should not
depend on the Company providing any such notice (even if such notices have been provided in the past or are provided in some but not all circumstances). 

6. Tax Consequences. You should consult a tax adviser for tax consequences relating to this SAR in the jurisdiction in
which you are subject to tax. YOU SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS SAR OR DISPOSING OF THE SHARES. You will not be allowed to exercise this SAR unless you make arrangements acceptable to the Company to pay Tax-Related Items that are required to be withheld as further described in Section 7 below. 

7. Responsibility for Taxes. Regardless of any action the Company or, if different, your employer (the
“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account and other tax-related items related to your participation
in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and
remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this SAR, including the grant, vesting or exercise of this SAR, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends;
and (b) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the SAR to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax
result. You acknowledge that if you are subject to Tax-Related Items in more than one jurisdiction, the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account
for Tax-Related Items in more than one jurisdiction. 
 Prior to any relevant taxable or tax
withholding event, as applicable, you shall pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy any withholding obligation the Company and/or the Employer may have for
Tax-Related Items. In this regard, you authorize the Company and/or the Employer, and their respective agents, at their discretion, to withhold all applicable
Tax-Related Items from your wages or other cash compensation paid to you by the Company and/or the Employer or by one or a combination of the following methods: (a) payment by you to the Company or the
Employer of an amount equal to the Tax-Related Items in cash, (b) having the Company withhold otherwise deliverable cash or Shares having a value equal to the
Tax-Related Items to be withheld, (c) delivering to the Company already-owned Shares having a value equal to the Tax-Related Items to be withheld,
(d) withholding from proceeds of the sale of the Shares either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf and you hereby authorize such sale pursuant to this authorization), or (e) any
other arrangement approved by the Company and permissible under applicable law; in all cases, under such rules as may be established by 












 
the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable; provided, however, that if
you are a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall be a mandatory sale under (d) above (unless the Committee shall establish an alternate method prior to the taxable or withholding
event). You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your participation in the Plan or your issuance
of Shares upon exercise of the SARs that cannot be satisfied by the means previously described. 
 Depending on the withholding method, the
Company may withhold or account for Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum applicable rate in which case you
may receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax
purposes, you are deemed to have been issued the full number of Shares subject to the vested SARs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related
Items. 
 Finally, you acknowledge that the Company has no obligation to deliver Shares or proceeds from the sale of Shares to you until you
have satisfied the obligations in connection with the Tax-Related Items as described in this Section. 

8. Acknowledgement. The Company and you agree that the SAR is granted under and governed by the Notice of Grant, this
Agreement and the provisions of the Plan (incorporated herein by reference). You: (i) acknowledge receipt of a copy of the Plan and the Plan prospectus, (ii) represent that you have carefully read and are familiar with their provisions and
the provisions of the Notice of Grant and this Agreement, and (iii) hereby accept the SAR subject to all of the terms and conditions set forth in this SAR Agreement and those set forth in the Plan and the Notice of Grant. You hereby agree to
accept as binding, conclusive and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice of Grant and the SAR Agreement. 

9. Entire Agreement; Enforcement of Rights. This Agreement, the Plan and the Notice of Grant constitute the entire
agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning this SAR are superseded. No modification of or amendment
to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing and signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as
a waiver of any rights of such party. 
 10. Compliance with Laws and Regulations. The issuance of Shares will be
subject to and conditioned upon compliance by the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the
Company’s common stock may be listed or quoted at the time of such issuance or transfer. The Shares issued pursuant to this Agreement shall be endorsed with appropriate legends, if any, determined by the Company. 

11. Governing Law; Severability. If one or more provisions of this Agreement are held to be unenforceable under
applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this
Agreement, (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with its terms. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law. For
purposes of litigating any dispute that may arise directly or indirectly from the Plan, the Notice of Grant and this Agreement, the parties hereby submit and consent to litigation in the exclusive jurisdiction of the State of Washington and agree
that any such litigation shall be conducted only in the courts of Washington in King County, Washington or the federal courts of the United States for the State of Washington and no other courts. 












 12. No Rights as Employee, Director or Consultant. Nothing in this
Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent, Subsidiary or Affiliate of the Company, to terminate your Service, for any reason, with or without Cause. 

13. Consent to Electronic Delivery and Acceptance of All Plan Documents and Disclosures. By your acceptance of
this SAR, you consent to the electronic delivery of the Notice of Grant, this Agreement, the Plan, account statements, Plan prospectuses required by the U.S. Securities and Exchange Commission, U.S. financial reports of the Company, and all other
documents that the Company is required to deliver to its security holders (including, without limitation, annual reports and proxy statements) or other communications or information related to the SAR. Electronic delivery may include the delivery of
a link to a Company intranet or the internet site of a third party involved in administering the Plan, the delivery of the document via e-mail or such other delivery determined at the Company’s
discretion. You acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost if you contact the Company by telephone, through a postal service or electronic mail at [insert email]. You further
acknowledge that you will be provided with a paper copy of any documents delivered electronically if electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third party a paper copy of
any documents delivered electronically if electronic delivery fails. You agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party
designated by the Company. Also, you understand that your consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if you have provided an electronic mail address), at any time by
notifying the Company of such revised or revoked consent by telephone, postal service or electronic mail at [insert email]. Finally, you understand that you are not required to consent to electronic delivery. 

14. Award Subject to Company Clawback or Recoupment. To the extent permitted by applicable law, the SAR shall be subject
to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or the Committee or required by law during the term of your employment or other Service that is applicable to you. In addition to any other
remedies available under such policy, applicable law may require the cancellation of your SAR (whether vested or unvested) and the recoupment of any gains realized with respect to your SAR. 

BY ACCEPTING THIS SAR, YOU AGREE TO ALL OF THE TERMS AND CONDITIONS DESCRIBED ABOVE AND IN THE PLAN.

 3.
Restrictions on Resale. By signing this Agreement, you agree not to sell any Shares acquired pursuant to the Plan and this Agreement at a time when applicable laws, regulations or Company or underwriter trading policies prohibit
exercise or sale. This restriction will apply as long as you are providing Service to the Company or a Subsidiary of the Company. 
 4. Tax
Consequences. YOU SHOULD CONSULT A TAX ADVISER BEFORE ACQUIRING THE SHARES IN THE JURISDICTION IN WHICH YOU ARE SUBJECT TO TAX. Shares shall not be issued under this Agreement unless you make arrangements acceptable to the Company to
pay any withholding taxes that may be due as a result of the acquisition of Shares. 
 5. Responsibility for Taxes. Regardless of any
action the Company or, if different, your employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account and other
tax-related items related to your participation in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the
ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and the
Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Stock Bonus Award, including the grant of the Stock Bonus Award,
the issuance of the Shares subject to the Stock Bonus Award, the subsequent sale of such Shares and the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of the Stock Bonus Award to reduce or

Tax-Related Items. In this regard, you authorize the Company and/or the Employer, and their respective agents, at their discretion, to withhold all applicable
Tax-Related Items from your wages or other cash compensation paid to you by the Company and/or the Employer or by one or a combination of the following methods: (a) payment by you to the Company or the

authorization), or (e) any other arrangement approved by the Company and permissible under applicable law; in 












 
all cases, under such rules as may be established by the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan
Policy, if applicable; provided, however, that if you are a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall be a mandatory sale under (d) above (unless the Committee shall establish an
alternate method prior to the taxable or withholding event). You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a
result of your participation in the Plan or the issuance of Shares subject to this Stock Bonus Award that cannot be satisfied by the means previously described. 

Depending on the withholding method, the Company may withhold or account for Tax-Related Items by
considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum applicable rate in which case you may receive a refund of any over-withheld amount in cash and will have no entitlement to the

otherwise be issued to you, for tax purposes, you are deemed to have been issued the full number of such Shares, notwithstanding that a number of the such Shares are held back solely for the purpose of paying the
Tax-Related Items. 
 Finally, you acknowledge that the Company has no obligation to deliver Shares
subject to the Stock Bonus Award to you until you have satisfied the obligations in connection with the Tax-Related Items as described in this Section.

Agreement and the provisions of the Plan (incorporated herein by reference). You: (i) acknowledge receipt of a copy of the Plan and the Plan prospectus, (ii) represent that you have carefully read and are familiar with their provisions and
the provisions of the Notice and this Agreement, and (iii) hereby accept the Stock Bonus Award subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. You hereby agree to accept as binding,
conclusive and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice and the Stock Bonus Award. 

7. Entire Agreement; Enforcement of Rights. This Agreement, the Plan and the Notice constitute the entire agreement and
understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning the purchase of the Shares hereunder are superseded. No modification of
or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing and signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be
construed as a waiver of any rights of such party. 
 8.
Compliance with Laws and Regulations. The issuance of Shares will be subject to and conditioned
upon compliance by the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s common stock may be
listed or quoted at the time of such issuance or transfer. The Shares issued pursuant to this Agreement shall be endorsed with appropriate legends, if any, determined by the Company. 

9. Stop Transfer Orders. 

(a) Stop-Transfer Notices. You agree that, in order to ensure compliance with the restrictions referred to herein, the Company
may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(b) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as the owner or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.













 10.
Governing Law; Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such
provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of this Agreement
shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with its terms. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of
the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law. For purposes of litigating any dispute that may arise directly or
indirectly from the Plan, the Notice and this Agreement, the parties hereby submit and consent to litigation in the exclusive jurisdiction of the State of Washington and agree that any such litigation shall be conducted only in the courts of
Washington in King County, Washington or the federal courts of the United States for the State of Washington and no other courts. 
 10. No
Rights as Employee, Director or Consultant. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent, Subsidiary or Affiliate of the Company, to terminate your Service, for any
reason, with or without Cause.

acceptance of this Stock Bonus Award, you consent to the electronic delivery of the Notice, this Agreement, the Plan, account statements, Plan prospectuses required by the Securities and Exchange Commission, U.S. financial reports of the Company,

 IMPEL NEUROPHARMA, INC. 

2021 EQUITY INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

Unless otherwise defined in this Stock Option Agreement (this “Option Agreement”), any capitalized terms used herein
will have the same meaning ascribed to them in the Impel NeuroPharma, Inc. 2021 Equity Incentive Plan (the “Plan”). 

Optionee has been granted an option to purchase Shares (the “Option”) of Impel NeuroPharma, Inc. (the
“Company”), subject to the terms, restrictions, and conditions of the Plan, the Notice of Stock Option Grant (the “Notice”), and this Option Agreement. In the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of the Notice or this Option Agreement, the terms and conditions of the Plan will prevail. 

1. Vesting. Subject to the applicable provisions of the Plan and this Option Agreement, the Option may be
exercised, in whole or in part, in accordance with the Vesting Schedule set forth in the Notice. Optionee acknowledges and agrees that the Vesting Schedule may change prospectively in the event Optionee’s Service status changes between full and
part-time and/or in the event Optionee is on a leave of absence, in accordance with Company policies relating to work schedules and vesting of Awards or as determined by the Committee. Optionee acknowledges that the vesting of the Option pursuant to
this Notice and Agreement is subject to Optionee’s continuing Service. 
 2. Grant of Option. Optionee has
been granted an Option for the number of Shares set forth in the Notice at the exercise price per Share in U.S. Dollars set forth in the Notice (the “Exercise Price”). If designated in the Notice as an Incentive Stock Option
(“ISO”), the Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if the Option is intended to be an ISO, to the extent that it exceeds the U.S. $100,000 rule of Code
Section 422(d) it will be treated as a Nonqualified Stock Option (“NSO”). 
 3. Termination Period.

 (a) General Rule. If Optionee’s Service terminates for any reason except death or Disability, and other than for Cause,
then the Option will expire at the close of business at Company headquarters on the date three (3) months after Optionee’s Termination Date (as defined below) (with any exercise beyond three (3) months after the date Optionee’s
employment terminates deemed to be the exercise of an NSO). The Company determines when Optionee’s Service terminates for all purposes under this Option Agreement. 

(b) Death; Disability. If Optionee dies before Optionee’s Service terminates (or Optionee dies within three (3) months of
Optionee’s termination of Service other than for Cause), then the Option will expire at the close of business at Company headquarters on the date twelve (12) months after the date of death (subject to the expiration details in
Section 7). If Optionee’s Service terminates because of Optionee’s Disability, then the Option will expire at the close of business at Company headquarters on the date twelve (12) months after Optionee’s Termination Date
(subject to the expiration details in Section 7). 
 (c) Cause. Unless otherwise determined by the Committee, the Option
(whether or not vested) will terminate immediately upon the Optionee’s cessation of Services if the Company reasonably determines in good faith that such cessation of Services has resulted in connection with an act or failure to act
constituting Cause (or the Optionee’s Services could have been terminated for Cause (without regard to the lapsing of any required notice or cure periods in connection therewith) at the time the Optionee terminated Services). 












 (d) No Notification of Exercise Periods. Optionee is responsible for keeping track of
these exercise periods following Optionee’s termination of Service for any reason. The Company will not provide further notice of such periods. In no event will the Option be exercised later than the Expiration Date set forth in the Notice.

 (e) Termination. For purposes of this Option, Optionee’s Service will be considered terminated as of the date Optionee is no
longer providing Service to the Company, its Parent or one of its Subsidiaries or Affiliates (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where
Optionee is employed or the terms of Optionee’s employment agreement, if any) (the “Termination Date”). The Committee will have the exclusive discretion to determine when Optionee is no longer actively providing services
for purposes of Optionee’s Option (including whether Optionee may still be considered to be providing services while on an approved leave of absence). Unless otherwise provided in this Option Agreement or determined by the Company,
Optionee’s right to vest in this Option under the Plan, if any, will terminate as of the Termination Date and will not be extended by any notice period (e.g., Optionee’s period of Service would not include any contractual notice
period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Optionee is employed or the terms of Optionee’s employment agreement, if any). Following the Termination Date, Optionee
may exercise the Option only as set forth in the Notice and this Section, provided that the period (if any) during which Optionee may exercise the Option after the Termination Date, if any, will commence on the date Optionee ceases to provide
services and will not be extended by any notice period mandated under employment laws in the jurisdiction where Optionee is employed or terms of Optionee’s employment agreement, if any. If Optionee does not exercise this Option within the
termination period set forth in the Notice or the termination periods set forth above, the Option will terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as set forth in the Notice. 

4. Exercise of Option. 

(a) Right to Exercise. The Option is exercisable during its term in accordance with the Vesting Schedule set forth in the Notice and
the applicable provisions of the Plan and this Option Agreement. In the event of Optionee’s death, Disability, termination for Cause, or other cessation of Service, the exercisability of the Option is governed by the applicable provisions of
the Plan, the Notice, and this Option Agreement. The Option may not be exercised for a fraction of a Share. 
 (b) Method of
Exercise. The Option is exercisable by delivery of an exercise notice in a form specified by the Company (the “Exercise Notice”), which will state the election to exercise the Option, the number of Shares in respect of
which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice will be delivered in
person, by mail, via electronic mail or facsimile or by other authorized method to the Secretary of the Company or other person designated by the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares together with any applicable Tax-Related Items (as defined in Section 8 below). The Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise
Notice accompanied by such aggregate Exercise Price and payment of any applicable Tax-Related Items. No Shares will be issued pursuant to the exercise of the Option unless such issuance and exercise complies
with all relevant provisions of law and the requirements of any stock exchange or quotation service upon which the Shares are then listed. Assuming such compliance, for United States income tax purposes the Exercised Shares will be considered
transferred to Optionee on the date the Option is exercised with respect to such Exercised Shares. 
 (c) Exercise by Another. If
another person wants to exercise the Option after it has been transferred to him or her in compliance with this Option Agreement, that person must prove to the Company’s satisfaction that he or she is entitled to exercise the Option. That
person must also complete the proper Exercise Notice form (as described above) and pay the Exercise Price (as described below) and any applicable Tax-Related Items (as described below). 












 5. Method of Payment. Payment of the aggregate Exercise Price
will be by any of the following, or a combination thereof, at the election of Optionee: 
 (a) Optionee’s personal check (or readily
available funds), wire transfer, or a cashier’s check; 
 (b) certificates for shares of Company stock that Optionee owns, along with
any forms needed to effect a transfer of those shares to the Company; the value of the shares, determined as of the effective date of the Option exercise, will be applied to the Exercise Price. Instead of surrendering shares of Company stock,
Optionee may attest to the ownership of those shares on a form provided by the Company and have the same number of shares subtracted from the Option shares issued to Optionee. However, Optionee may not surrender, or attest to the ownership of,
shares of Company stock in payment of the Exercise Price of Optionee’s Option if Optionee’s action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to this Option for financial
reporting purposes; 
 (c) cashless exercise through irrevocable directions to a securities broker approved by the Company to sell all or
part of the Shares covered by the Option and to deliver to the Company from the sale proceeds an amount sufficient to pay the Exercise Price and any applicable Tax-Related Items. The balance of the sale
proceeds, if any, will be delivered to Optionee. The directions must be given by signing a special notice of exercise form provided by the Company; or 

(d) any other method authorized by the Company; 

provided, however, that the Company may restrict the available methods of payment to facilitate compliance with applicable law or administration of the Plan.

 6. Non-Transferability of Option. In general, except as provided
below, only Optionee may exercise this Option prior to Optionee’s death. Optionee may not transfer or assign this Option, except as provided below. For instance, Optionee may not sell this Option or use it as security for a loan. If Optionee
attempts to do any of these things, this Option will immediately become invalid. However, if Optionee is a U.S. taxpayer, Optionee may dispose of this Option in Optionee’s will. If Optionee is a U.S. taxpayer and this Option is designated as a
NSO in the Notice of Grant, then the Committee may, in its sole discretion, allow Optionee to transfer this Option as a gift to one or more family members. For purposes of this Agreement, “family member” means a child, stepchild,
grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in- law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law (including adoptive relationships), any individual sharing
Optionee’s household (other than a tenant or employee), a trust in which one or more of these individuals have more than 50% of the beneficial interest, a foundation in which Optionee or one or more of these persons control the management of
assets, and any entity in which Optionee or one or more of these persons own more than 50% of the voting interest. In addition, if Optionee is a U.S. taxpayer and this Option is designated as a NSO in the Notice of Grant, then the Committee may, in
its sole discretion, allow Optionee to transfer this Option to Optionee’s spouse or former spouse pursuant to a domestic relations order in settlement of marital property rights. The Committee will allow Optionee to transfer this Option only if
both Optionee and the transferee(s) execute the forms prescribed by the Committee, which include the consent of the transferee(s) to be bound by this Agreement. This Option may not be transferred in any manner other than by will or by the laws of
descent or distribution or court order and may be exercised during Optionee’s lifetime only by Optionee, Optionee’s guardian, or legal representative, as permitted in the Plan and applicable local laws. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of Optionee. 
 7. Term of
Option. The Option will in any event expire on the expiration date set forth in the Notice, which date is no more than ten (10) years after the Date of Grant (five (5) years after the Date of Grant if this option is
designated as an ISO in the Notice of Stock Option Grant and Section 5.3 of the Plan applies). 












 8. Taxes. 

(a) Responsibility for Taxes. Optionee acknowledges that, regardless of any action taken by the Company or, if different, a Parent,
Subsidiary, or Affiliate employing or retaining Optionee (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account, or other tax related items related
to Optionee’s participation in the Plan and legally applicable to Optionee (“Tax-Related Items”) is and remains Optionee’s responsibility and may exceed the amount actually
withheld by the Company or the Employer, if any. Optionee further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related
Items in connection with any aspect of this Option, including, but not limited to, the grant, vesting, or exercise of this Option; the subsequent sale of Shares acquired pursuant to such exercise; and the receipt of any dividends; and (ii) do
not commit to and are under no obligation to structure the terms of the grant or any aspect of this Option to reduce or eliminate Optionee’s liability for Tax-Related Items or achieve any particular tax
result. Further, if Optionee is subject to Tax-Related Items in more than one jurisdiction, Optionee acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to
withhold or account for Tax-Related Items in more than one jurisdiction. OPTIONEE SHOULD CONSULT A TAX ADVISER APPROPRIATELY QUALIFIED IN THE COUNTRY OR COUNTRIES IN WHICH OPTIONEE RESIDES OR IS SUBJECT TO
TAXATION. 
 (b) Withholding. Prior to any relevant taxable or tax withholding event, as applicable, Optionee agrees to
make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Optionee authorizes the Company and/or the Employer, or their respective agents, at their
discretion, to satisfy any withholding obligations for Tax-Related Items by one or a combination of the following, all under such rules as may be established by the Committee and in compliance with the
Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable: 
  

	 	(i)	 withholding from Optionee’s wages or other cash compensation paid to Optionee by the Company and/or the
Employer; or 


  

	 	(ii)	 withholding from proceeds of the sale of Shares acquired at exercise of this Option either through a voluntary
sale or through a mandatory sale arranged by the Company (on Optionee’s behalf pursuant to this authorization and without further consent); 


  

	 	(iii)	 withholding Shares to be issued upon exercise of the Option, provided the Company only withholds the number of
Shares necessary to satisfy no more than applicable statutory withholding amounts; 


  

	 	(iv)	 Optionee’s payment of a cash amount (including by check representing readily available funds or a wire
transfer); or 


  

	 	(v)	 any other arrangement approved by the Committee and permitted under applicable law; 



provided, however, that if Optionee is a Section 16 officer of the Company under the Exchange Act, then the method of withholding shall
be a mandatory sale (unless the Committee as constituted in accordance with Rule 16b-3 of the Exchange Act shall establish an alternate method from alternatives (i) – (v) above prior to the Tax-Related Items withholding event). 
 Depending on the withholding method, the Company may withhold or
account for Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including up to the maximum permissible statutory rate for Optionee’s tax
jurisdiction(s) in which case Optionee will have no entitlement to the equivalent amount in Shares and will receive a refund of any over-withheld amount in cash in accordance with applicable law. If the obligation for
Tax-Related Items is satisfied by withholding in Shares, for tax purposes, Optionee is deemed to have been issued the full number of Exercised Shares; notwithstanding that a number of the Shares are held back
solely for the purpose of satisfying the withholding obligation for Tax-Related Items. 












 Finally, Optionee agrees to pay to the Company and/or the Employer any amount of Tax-Related Items that the Company and/or the Employer may be required to withhold or account for as a result of Optionee’s participation in the Plan that cannot be satisfied by the means previously described.
The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if Optionee fails to comply with Optionee’s obligations in connection with the Tax-Related Items. 

(c) Notice of Disqualifying Disposition of ISO Shares. If Optionee is subject to Tax-Related
Items in the United States and sells or otherwise disposes of any of the Shares acquired pursuant to an ISO on or before the later of (i) two (2) years after the grant date, or (ii) one (1) year after the exercise date, Optionee
will immediately notify the Company in writing of such disposition. Optionee agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized from such early disposition of ISO Shares by payment in
cash or out any wages or other cash compensation paid to Optionee by the Company and/or the Employer. 
 9. Nature of
Grant. By accepting the Option, Optionee acknowledges, understands and agrees that: 
 (a) the Plan is established voluntarily
by the Company, it is discretionary in nature, and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan; 

(b) the grant of the Option is exceptional, voluntary, and occasional, and does not create any contractual or other right to receive future
grants of options, or benefits in lieu of options, even if options have been granted in the past; 
 (c) all decisions with respect to
future options or other grants, if any, will be at the sole discretion of the Company; 
 (d) Optionee is voluntarily participating in the
Plan; 
 (e) the Option and Optionee’s participation in the Plan will not create a right to employment or be interpreted as forming or
amending an employment or service contract with the Company or the Employer, and will not interfere with the ability of the Company or the Employer, as applicable, to terminate Optionee’s employment or service relationship (if any); 

(f) the Option and the Shares subject to the Option, and the income and value of same, are not intended to replace any pension rights or
compensation; 
 (g) the Option and the Shares subject to the Option, and the income and value of same, are not part of normal or expected
compensation for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments,
bonuses, long-service awards, pension or retirement, or welfare benefits or similar payments; 
 (h) unless otherwise agreed with the
Company, the Option, and the Shares subject to the Option, and the income and value of same, are not granted as consideration for, or in connection with, the service Optionee may provide as a director of a Parent, Subsidiary, or Affiliate; 

(i) the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty; if the underlying
Shares do not increase in value, the Option will have no value; if Optionee exercises the Option and acquires Shares, the value of such Shares may increase or decrease, even below the Exercise Price; 












 (j) no claim or entitlement to compensation or damages will arise from forfeiture of the
Option resulting from Optionee’s termination of Service (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Optionee is employed or the terms of
Optionee’s employment agreement, if any), and in consideration of the grant of the Option to which Optionee is otherwise not entitled, Optionee irrevocably agrees never to institute any claim against the Employer, the Company, and any Parent,
Subsidiary, or Affiliate; waives his or her ability, if any, to bring any such claim; and releases the Employer, the Company, and any Parent, Subsidiary, or Affiliate from any such claim; if, notwithstanding the foregoing, any such claim is allowed
by a court of competent jurisdiction, then, by participating in the Plan, Optionee will be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such
claim; 
 (k) unless otherwise provided in the Plan or by the Company in its discretion, the Option and the benefits evidenced by this
Option Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any Corporate Transaction affecting the
Shares; and 
 (l) neither the Employer, the Company, or any Parent, Subsidiary or Affiliate will be liable for any foreign exchange rate
fluctuation between Optionee’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Optionee pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon
exercise. 
 (m) the following provisions apply only if Optionee is providing services outside the United States: 

 

	 	(i)	 the Option and the Shares subject to the Option are not part of normal or expected compensation or salary for
any purpose; and 


  

	 	(ii)	 Optionee acknowledges and agrees that neither the Company, the Employer nor any Parent or Subsidiary or
Affiliate will be liable for any foreign exchange rate fluctuation between Optionee’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Optionee pursuant to the exercise of the Option
or the subsequent sale of any Shares acquired upon exercised 


 10. No Advice Regarding Grant.
The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Optionee’s participation in the Plan or Optionee’s acquisition or sale of the underlying Shares. Optionee
acknowledges, understands, and agrees that he or she should consult with his or her own personal tax, legal, and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

11. Language. If Optionee has received this Option Agreement, or any other document related to the Option and/or
the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control. 

12. Imposition of Other Requirements. The Company reserves the right to impose other requirements on
Optionee’s participation in the Plan, on the Option, and on any Shares purchased upon exercise of the Option, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Optionee to sign
any additional agreements or undertakings that may be necessary to accomplish the foregoing. 
 13.
Acknowledgement. The Company and Optionee agree that the Option is granted under and governed by the Notice, this Option Agreement and the Plan (incorporated herein by reference). Optionee: (a) acknowledges receipt of a
copy of the Plan and the Plan prospectus, (b) represents that Optionee has carefully read and is familiar with their provisions, and (c) hereby accepts the Option subject to all of the terms and conditions set forth herein and those set
forth in the Plan and the Notice. 












 14. Entire Agreement; Enforcement of Rights. This Option
Agreement, the Plan, and the Notice constitute the entire agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments, or negotiations
concerning the purchase of the Shares hereunder are superseded. No adverse modification of, or adverse amendment to, this Option Agreement, nor any waiver of any rights under this Option Agreement, will be effective unless in writing and signed by
the parties to this Option Agreement (which writing and signing may be electronic). The failure by either party to enforce any rights under this Option Agreement will not be construed as a waiver of any rights of such party. 

15. Compliance with Laws and Regulations. The issuance of Shares and the sale of Shares will be subject to and
conditioned upon compliance by the Company and Optionee with all applicable state, federal, local and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s
Shares may be listed or quoted at the time of such issuance or transfer. Optionee understands that the Company is under no obligation to register or qualify the Common Stock with any state, federal, or foreign securities commission or to seek
approval or clearance from any governmental authority for the issuance or sale of the Shares. Further, Optionee agrees that the Company will have unilateral authority to amend the Plan and this Option Agreement without Optionee’s consent to the
extent necessary to comply with securities or other laws applicable to issuance of Shares. Finally, the Shares issued pursuant to this Option Agreement will be endorsed with appropriate legends, if any, determined by the Company. 

16. Severability. If one or more provisions of this Option Agreement are held to be unenforceable under applicable
law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (a) such provision will be excluded from this Option
Agreement, (b) the balance of this Option Agreement will be interpreted as if such provision were so excluded and (c) the balance of this Option Agreement will be enforceable in accordance with its terms. 

17. Governing Law and Venue. This Option Agreement and all acts and transactions pursuant hereto and the rights
and obligations of the parties hereto will be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to such state’s conflict of laws rules. 

Any and all disputes relating to, concerning or arising from this Option Agreement, or relating to, concerning or arising from the
relationship between the parties evidenced by the Plan or this Option Agreement, will be brought and heard exclusively in the United States District Court for the State of Washington or the Superior Court, King County, Washington. Each of the
parties hereby represents and agrees that such party is subject to the personal jurisdiction of said courts; hereby irrevocably consents to the jurisdiction of such courts in any legal or equitable proceedings related to, concerning, or arising from
such dispute, and waives, to the fullest extent permitted by law, any objection which such party may now or hereafter have that the laying of the venue of any legal or equitable proceedings related to, concerning, or arising from such dispute which
is brought in such courts is improper or that such proceedings have been brought in an inconvenient forum. 
 18. No Rights as
Employee, Director or Consultant. Nothing in this Option Agreement will affect in any manner whatsoever any right or power of the Employer or the Company to terminate Optionee’s Service, for any reason, with or without Cause.

 19. Lock-Up Agreement. In connection with the initial public offering of the
Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby agrees not to sell, make any short sale of, loan, grant any option for the purchase
of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration), except pursuant to a transfer for no consideration in accordance with Section 6 above, without the prior
written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such managing
underwriters and to execute 












 
an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering; provided however that, if during the last seventeen (17) days of the
restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the
sixteen (16)-day period beginning on the last day of the restricted period, then, upon the request of the managing underwriter, to the extent required by any Financial Industry Regulatory Authority rules, the
restrictions imposed by this Section shall continue to apply until the end of the third trading day following the expiration of the fifteen (15)-day period beginning on the issuance of the earnings release or
the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred sixteen (216) days after the effective date of the registration statement. 

20. Consent to Electronic Delivery of All Plan Documents and Disclosures. By Optionee’s acceptance of the
Notice (whether in writing or electronically), Optionee and the Company agree that the Option is granted under and governed by the terms and conditions of the Plan, the Notice, and this Option Agreement. Optionee has reviewed the Plan, the Notice,
and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing the Notice and Agreement, and fully understands all provisions of the Plan, the Notice, and this Option Agreement. Optionee hereby
agrees to accept as binding, conclusive, and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice, and this Option Agreement. Optionee further agrees to notify the Company upon any change in
Optionee’s residence address. By acceptance of the Option, Optionee agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party
designated by the Company and consents to the electronic delivery of the Notice, this Option Agreement, the Plan, account statements, Plan prospectuses required by the U.S. Securities and Exchange Commission, U.S. financial reports of the Company,
and all other documents that the Company is required to deliver to its security holders (including, without limitation, annual reports and proxy statements), or other communications or information related to the Option and current or future
participation in the Plan. Electronic delivery may include the delivery of a link to the Company intranet or the internet site of a third party involved in administering the Plan, the delivery of the document via
e-mail, or such other delivery determined at the Company’s discretion. Optionee acknowledges that Optionee may receive from the Company a paper copy of any documents delivered electronically at no cost if
Optionee contacts the Company by telephone, through a postal service, or electronic mail to Stock Administration. Optionee further acknowledges that Optionee will be provided with a paper copy of any documents delivered electronically if electronic
delivery fails; similarly, Optionee understands that Optionee must provide on request to the Company or any designated third party a paper copy of any documents delivered electronically if electronic delivery fails. Also, Optionee understands that
Optionee’s consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if Optionee has provided an electronic mail address), at any time by notifying the Company of such revised or
revoked consent by telephone, postal service, or electronic mail to Stock Administration. Finally, Optionee understands that Optionee is not required to consent to electronic delivery if local laws prohibit such consent. 

21. Insider Trading Restrictions/Market Abuse Laws. Optionee acknowledges that, depending on Optionee’s
country, Optionee may be subject to insider trading restrictions and/or market abuse laws, which may affect Optionee’s ability to acquire or sell the Shares or rights to Shares under the Plan during such times as Optionee is considered to have
“inside information” regarding the Company (as defined by the laws in Optionee’s country). Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable
Company insider trading policy. Optionee acknowledges that it is Optionee’s responsibility to comply with any applicable restrictions and understands that Optionee should consult his or her personal legal advisor on such matters. In addition,
Optionee acknowledges that he or she has read the Company’s Insider Trading Policy, and agrees to comply with such policy, as it may be amended from time to time, whenever Optionee acquires or disposes of the Company’s securities. 












 22. Award Subject to Company Clawback or Recoupment. To the
extent permitted by applicable law, the Option will be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of Optionee’s employment or other
Service that is applicable to Optionee. In addition to any other remedies available under such policy and applicable law, the Company may require the cancellation of Optionee’s Option (whether vested or unvested) and the recoupment of any gains
realized with respect to Optionee’s Option. 
 BY ACCEPTING THIS OPTION, OPTIONEE AGREES TO ALL OF THE TERMS AND CONDITIONS
DESCRIBED ABOVE AND IN THE PLAN.
