HELIUS MEDICAL TECHNOLOGIES, INC. 

2021 INDUCEMENT PLAN 

ADOPTED BY THE BOARD OF DIRECTORS:
JULY 2, 2021 
 1.    GENERAL. 

(a)    Eligible Award Recipients. The only persons eligible to receive grants of Awards under this Plan
are individuals who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) or 5635(c)(3), if applicable, and the related guidance under Nasdaq IM 5635-1 (together with any
analogous rules or guidance effective after the date hereof, the “Inducement Award Rules”). A person who previously served as an Employee or Director will not be eligible to receive Awards under
this Plan, other than following a bona fide period of non-employment. Persons eligible to receive grants of Awards under this Plan are referred to in this Plan as “Eligible
Employees.” These Awards must be approved by either a majority of the Company’s “Independent Directors” (as such term is defined in Nasdaq Marketplace
Rule 5605(a)(2)) or the Company’s compensation committee, provided such committee comprises solely of two (2) or more Independent Directors to whom authority has been delegated by the Board in accordance with Section 2(c) (the
“Committee”) in order to comply with the exemption from the stockholder approval requirement for “inducement grants” provided under the Inducement Award Rules. 

(b)    Available Awards. This Plan provides for the grant of the following Awards: (i) Options,
(ii) Stock Appreciation Rights, (iii) Restricted Stock Awards, (iv) Restricted Stock Unit Awards, (v) Performance Stock Awards, (vi) Performance Cash Awards and (vii) Other Stock Awards. All Options shall be
Nonstatutory Stock Options. 
 (c)    Purpose. This Plan, through the grant of Awards, is intended to
provide (i) an inducement material for certain individuals to enter into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Marketplace Rules, (ii) incentives for such persons to exert maximum efforts for the
success of the Company and any Affiliate and (iii) a means by which Eligible Employees may be given an opportunity to benefit from increases in value of the Common Stock. 

2.    ADMINISTRATION. 

(a)    Administration by Board. The Board will administer this Plan; provided, however, that Awards may
only be granted by either (i) a majority of the Company’s Independent Directors or (ii) the Committee. Subject to those constraints and the other constraints of the Inducement Award Rules, the Board may delegate some of its powers of
administration of this Plan to a Committee or Committees, as provided in Section 2(c). 
 (b)    Powers
of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of this Plan and the Inducement Award Rules: 

  
 1 

 (i)    To determine: (A) who will be granted Awards;
(B) when and how each Award will be granted; (C) what type of Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or
Common Stock under the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value applicable to an Award; provided, however, that Awards may only be granted by either
(i) a majority of the Company’s Independent Directors or (ii) the Committee. 
 (ii)    To
construe and interpret this Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for administration of this Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or
inconsistency in this Plan or in any Award Agreement, in a manner and to the extent it will deem necessary or expedient to make this Plan or Award fully effective. 

(iii)    To settle all controversies regarding this Plan and Awards granted under it. 

(iv)    To accelerate, in whole or in part, the time at which an Award may be exercised or vest (or the time at
which cash or shares of Common Stock may be issued in settlement thereof). 
 (v)    To suspend or terminate
this Plan at any time. Except as otherwise provided in this Plan or an Award Agreement, suspension or termination of this Plan will not materially impair a Participant’s rights under the Participant’s then-outstanding Award without
the Participant’s written consent, except as provided in subsection (viii) below. 
 (vi)    To amend
this Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments relating to certain nonqualified deferred compensation under Section 409A of the Code and/or to ensure this Plan or Awards
granted under this Plan are exempt from, or compliant with, the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. Except as provided in
Section 9(a) relating to Capitalization Adjustments, if required by applicable law or listing requirements, the Company shall seek stockholder approval for any amendment of this Plan. Except as otherwise provided in
this Plan or an Award Agreement, no amendment of this Plan will materially impair a Participant’s rights under an outstanding Award without the Participant’s written consent. 

(vii)    To submit any amendment to this Plan for stockholder approval, including, but not limited to, amendments
to this Plan intended to satisfy the requirements of Rule 16b-3 or to comply with other applicable laws or listing requirements. 

(viii)    To approve forms of Award Agreements for use under this Plan and to amend the terms of any one or more
Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in this Plan that are not subject to Board discretion; provided,
however, that a Participant’s rights under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and (B) such Participant consents in writing. Notwithstanding the
foregoing, (1) a Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole 

  
 2 

 
discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board
may amend the terms of any one or more Awards without the affected Participant’s consent (A) to clarify the manner of exemption from, or to bring the Award into compliance with, Section 409A of the Code and the Department of Treasury
regulations and other interpretive guidance issued thereunder (including, without limitation, such guidance as may be issued after the Effective Date); or (B) to comply with other applicable laws or listing requirements. 

(ix)    Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to
promote the best interests of the Company and that are not in conflict with the provisions of this Plan or Awards. 

(x)    To adopt such procedures and sub-plans as are necessary or
appropriate to permit participation in this Plan by Eligible Employees who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to this Plan or any Award
Agreement that are required for compliance with the laws of the relevant foreign jurisdiction). 
 (c)    Delegation
to Committee. 
 (i)    General. Subject to the terms of Section 4(b),
the Board may delegate some or all of the administration of this Plan to a Committee or Committees. If administration of this Plan is delegated to a Committee, the Committee will have, in connection with the administration of this Plan, the
powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this
Plan to the Board will thereafter be construed as being to the Committee or subcommittee, as applicable). Any delegation of administrative powers will be reflected in resolutions, not inconsistent with the provisions of this Plan, adopted from
time to time by the Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee and/or revest in the Committee any powers delegated to the subcommittee. The Board may retain the authority to concurrently
administer this Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. 

(ii)    Rule 16b-3 Compliance. The Committee may consist
solely of two or more Non-Employee Directors in accordance with Rule 16b-3. 

(d)    Effect of Board’s Decision. All determinations, interpretations and constructions
made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 

(e)    Repricing; Cancellation and Re-Grant of Awards. Neither
the Board nor any Committee will have the authority to reduce the exercise, purchase or strike price of any outstanding Option or SAR, unless the stockholders of the Company have approved such an action within twelve (12) months prior to such
an event.

 3.    SHARES SUBJECT TO
THIS PLAN. 
 (a)    Share Reserve. Subject to
Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Awards will not exceed 100,000 shares (the “Share Reserve”). No
Participant in the Plan may be granted an Award during the term of the Plan in excess of the Share Reserve. For clarity, the Share Reserve is a limitation in the number of shares of Common Stock that may be issued pursuant to the Plan and does not
limit the granting of Awards except as provided in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by Nasdaq Marketplace Rule 5635(c) or, if applicable NYSE Listed Company Manual Section 303A.08,
AMEX Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under this Plan. 

(b)    Reversion of Shares to the Share Reserve. If an Award or any portion thereof (i) expires or
otherwise terminates without all of the shares covered by such Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or
otherwise offset) the number of shares of Common Stock that may be available for issuance under this Plan. If any shares of Common Stock issued pursuant to an Award are forfeited back to or repurchased or reacquired by the Company for any
reason, including because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under
this Plan. Any shares reacquired by the Company in satisfaction of tax withholding obligations on an Award or as consideration for the exercise or purchase price of an Award will again become available for issuance under this Plan. 

(c)    Source of Shares. The stock issuable under this Plan will be shares of authorized but unissued
or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise. 

4.    ELIGIBILITY. 

(a)    Eligibility for Specific Awards. Awards may only be granted to persons who are Eligible Employees
described in Section 1(a) of this Plan, where the Award is an inducement material to the individual’s entering into employment with the Company or an Affiliate within the meaning of Rule 5635(c)(4) of the Nasdaq
Marketplace Rules or is otherwise permitted pursuant to Rule 5635(c) of the Nasdaq Marketplace Rules, provided, however, that Awards may not be granted to Eligible Employees who are providing Continuous Service only to any “parent”
of the Company, as such term is defined in Rule 405 of the Securities Act, unless (i) the stock underlying such Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Awards are
granted pursuant to a corporate transaction such as a spin off transaction), (ii) the Company, in consultation with its legal counsel, has determined that such Awards are otherwise exempt from Section 409A of the Code, or (iii) the
Company, in consultation with its legal counsel, has determined that such Awards comply with the distribution requirements of Section 409A of the Code. 

  
 4 

 (b)    Approval Requirements. All Awards granted must be
approved either by a majority of the Company’s Independent Directors or the Committee. 

5.    PROVISIONS RELATING TO OPTIONS
AND STOCK APPRECIATION RIGHTS. Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will be Nonstatutory Stock
Options at the time of grant. The provisions of separate Options or SARs need not be identical; provided, however, that each Award Agreement will conform to (through incorporation of provisions hereof by reference in the applicable Award
Agreement or otherwise) the substance of each of the following provisions: 
 (a)    Term. No Option
or SAR will be exercisable after the expiration of 10 years from the date of its grant or such shorter period specified in the Award Agreement. 

(b)    Exercise Price. The exercise or strike price of each Option or SAR will be not less than 100% of
the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than 100% of the Fair Market Value of the
Common Stock subject to the Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of
Section 409A of the Code. Each SAR will be denominated in shares of Common Stock equivalents. 

(c)    Purchase Price for Options. The purchase price of Common Stock acquired pursuant to the exercise
of an Option may be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board will have the authority to grant Options that do
not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of payment. The permitted methods of payment
are as follows: 
 (i)    by cash, check, bank draft or money order payable to the Company; 

(ii)    pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior
to the issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 

(iii)    by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

(iv)    by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares
of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company will accept a cash or other payment from the
Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of Common Stock will no longer

  
 5 

 
be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net
exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 

(v)    in any other form of legal consideration that may be acceptable to the Board and specified in the
applicable Award Agreement. 
 (d)    Exercise and Payment of a SAR. To exercise any outstanding SAR,
the Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not
greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested
under such SAR, and with respect to which the Participant is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such
date. The appreciation distribution may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Award Agreement evidencing such SAR. 

(e)    Transferability of Options and SARs. The Board may, in its sole discretion, impose such
limitations on the transferability of Options and SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i)    Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the
laws of descent and distribution (or pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that
is not prohibited by applicable tax and securities laws. Except as explicitly provided in this Plan, neither an Option nor a SAR may be transferred for consideration. 

(ii)    Domestic Relations Orders. Subject to the approval of the Board or a duly authorized Officer,
an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument. 

(iii)    Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a
Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the death of the Participant, will thereafter be entitled to exercise the Option or SAR and
receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, upon the death of the Participant the executor or administrator of the Participant’s estate will be entitled to exercise
the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation
would be inconsistent with the provisions of applicable laws. 

  
 6 

 (f)    Vesting Generally. The total number of shares
of Common Stock subject to an Option or SAR may vest and become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not
be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this
Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of Common Stock as to which an Option or SAR may be exercised. 

(g)    Termination of Continuous Service. Except as otherwise provided in the applicable Award
Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than upon the Participant’s death or Disability), the Participant may exercise his or
her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) within the period of time ending on the earlier of (i) the date that is three (3) months
following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement, which period will not be less than thirty (30) days if necessary to comply with applicable
laws unless such termination is for Cause) and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or
SAR (as applicable) within the applicable time frame, the Option or SAR will terminate. 
 (h)    Extension of
Termination Date. Except as otherwise provided in the applicable Award Agreement or other written agreement between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s
Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the
Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of time (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the
Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award
Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received on exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other
than for Cause) would violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a period of months (that need not be consecutive) equal to the applicable post-termination
exercise period after the termination of the Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or
(ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. 

  
 7 

 (i)    Disability of Participant. Except as otherwise
provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her
Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date twelve
(12) months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement, which period will not be less than six (6) months if necessary to comply with applicable laws) and
(ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option
or SAR (as applicable) will terminate.
 (j)    Death of Participant. Except as otherwise provided in
the applicable Award Agreement or other agreement between the Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the
period (if any) specified in the Award Agreement for exercisability after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled
to exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the
Participant’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Award Agreement, which period will not be less
than six (6) months if necessary to comply with the applicable laws) and (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not
exercised within the applicable time frame, the Option or SAR (as applicable) will terminate. 

(k)    Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award
Agreement or other individual written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate immediately upon such Participant’s
termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. 

(l)    Non-Exempt Employees. If an Option or SAR is granted to
an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six
(6) months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such
non-exempt Employee dies or suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or
(iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement, in another agreement between the Participant and the Company, or, if no such definition, in accordance with the Company’s
then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six (6) months following the date of grant. The foregoing provision is intended to operate so that any income
derived by a non-exempt employee in connection with the 

  
 8 

 
exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the extent permitted and/or required for compliance with the Worker Economic Opportunity Act to
ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Award will be exempt from the employee’s regular rate of pay, the
provisions of this Section 5(l) will apply to all Awards and are hereby incorporated by reference into such Award Agreements. 

6.    PROVISIONS OF AWARDS OTHER THAN
OPTIONS AND SARS. 
 (a)    Restricted Stock
Awards. Each Restricted Stock Award Agreement will be in such form and will contain such terms and conditions as the Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares
of Common Stock may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which certificate will be held in such
form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical.
Each Restricted Stock Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

(i)    Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash,
check, bank draft or money order payable to the Company, (B) past or future services to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible
under applicable law. 
 (ii)    Vesting. Shares of Common Stock awarded under the Restricted Stock
Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii)    Termination of Participant’s Continuous Service. If a Participant’s Continuous
Service terminates, the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant as of the date of termination of Continuous Service under the terms of the Restricted
Stock Award Agreement. 
 (iv)    Transferability. Rights to acquire shares of Common Stock under
the Restricted Stock Award Agreement will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will determine in its sole discretion, so long as Common Stock
awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement. 

(v)    Dividends. A Restricted Stock Award Agreement may provide that any dividends paid
on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

  
 9 

 (b)    Restricted Stock Unit
Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and conditions as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may
change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical. Each Restricted Stock Unit Award Agreement will conform to (through incorporation of the provisions hereof by
reference in the Agreement or otherwise) the substance of each of the following provisions: 

(i)    Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine
the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock subject to
a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii)    Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board
may impose such restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

(iii)    Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of Common
Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 

(iv)    Additional Restrictions. At the time of the grant of a Restricted Stock Unit
Award, the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such
Restricted Stock Unit Award. 
 (v)    Dividend Equivalents. Dividend equivalents may be credited in
respect of shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted
into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will
be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 

(vi)    Termination of Participant’s Continuous Service. Except as
otherwise provided in the applicable Restricted Stock Unit Award Agreement or other written agreement between a Participant and the Company or an Affiliate, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon
the Participant’s termination of Continuous Service. 
 (c)    Performance Awards. 

(i)    Performance Stock Awards. A Performance Stock Award is an Award that is payable (including that
may be granted, may vest or may be exercised) contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance 

  
 10 

 
Stock Award may, but need not, require the Participant’s completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved
during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the Board or Committee, in its sole discretion. In addition, to the extent permitted by
applicable law and the applicable Award Agreement, the Board or the Committee may determine that cash may be used in payment of Performance Stock Awards. 

(ii)    Performance Cash Awards. A Performance Cash Award is a cash award that is payable contingent
upon the attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service. At the time of grant of a Performance Cash Award, the
length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the Board or Committee,
in its sole discretion. The Board or Committee may specify the form of payment of Performance Cash Awards, which may be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such
portion thereof as the Board may specify, to be paid in whole or in part in cash or other property. 

(iii)    Discretion. A majority of the Company’s Independent Directors or the Committee retains
the discretion to adjust or eliminate the compensation or economic benefit due upon attainment of Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period. Partial achievement
of the specified criteria may result in the payment or vesting corresponding to the degree of achievement as specified in the Award Agreement or the written terms of a Performance Cash Award. 

(d)    Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or
otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common Stock at the time of grant) may be granted
either alone or in addition to Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of this Plan, a majority of the Company’s
Independent Directors or the Committee will have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent
thereof) to be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards. 

7.    COVENANTS OF THE COMPANY. 

(a)    Availability of Shares. The Company will keep available at all times the number of shares of
Common Stock reasonably required to satisfy then-outstanding Awards. 
 (b)    Securities Law
Compliance. The Company will seek to obtain from each regulatory commission or agency having jurisdiction over this Plan, as necessary, such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon
exercise

or vesting of the Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act, or other securities or applicable laws, this Plan, any
Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the
Company deems necessary or advisable for the lawful issuance and sale of Common Stock under this Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise or vesting of such Awards unless and
until such authority is obtained. A Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock pursuant to the Award if such grant or issuance would be in violation of any applicable securities law.

 (c)    No Obligation to Notify or Minimize Taxes. The Company will have no duty or
obligation to any Participant to advise such holder as to the tax treatment or time or manner of exercising such Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or
expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award. 

8.    MISCELLANEOUS. 

(a)    Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of
Common Stock pursuant to Awards will constitute general funds of the Company. 
 (b)    Corporate Action
Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when
the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the
corporate action approving the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the papering of the
Award Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents. 

(c)    Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Award pursuant to its
terms, and (ii) the issuance of the Common Stock subject to such Award has been entered into the books and records of the Company. 

(d)    No Employment or Other Service Rights. Nothing in this Plan, any Award Agreement or any other
instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or will
affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or 

  
 12 

 
without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the
service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state or foreign jurisdiction in which the Company or the Affiliate is domiciled or incorporated, as the case may
be. 
 (e)    Change in Time Commitment. In the event a Participant’s regular level of time
commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time
Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding reduction in the number of shares or
cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule
applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended. 

(f)    Investment Assurances. The Company may require a Participant, as a condition of exercising or
acquiring Common Stock under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably
satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that such Participant is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award;
and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise
distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Award has
been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under this Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 

(g)    Withholding Obligations. Unless prohibited by the terms of an Award Agreement, the Company may,
in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment;
(ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; provided, however, that no shares of Common Stock are withheld with a value exceeding
the maximum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash;
(iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award Agreement. 

  
 13 

 (h)    Electronic Delivery. Any reference herein to a
“written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium
controlled by the Company to which the Participant has access). 
 (i)    Deferrals. To the extent
permitted by applicable law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish
programs and procedures for deferral elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for
distributions while a Participant is still an employee or otherwise providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments,
including lump sum payments, following the Participant’s termination of Continuous Service, and implement such other terms and conditions consistent with the provisions of this Plan and in accordance with applicable law. 

(j)    Compliance with Section 409A of the Code. Unless otherwise
expressly provided for in an Award Agreement, this Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes this Plan and the Awards granted hereunder exempt from Section 409A of the Code, and, to the
extent not so exempt, in compliance with Section 409A of the Code. If the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement evidencing such
Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby
incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant
holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code, no distribution or payment of any amount that is due because
of a “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six months following the date of such Participant’s
“separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a
manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule. Notwithstanding any provision
of this Plan, in no event will the Company be liable for any additional tax, interest or penalty imposed upon or other detriment suffered by a Participant under Section 409A of the Code or for any damages suffered by such Participant for any
failure of this Plan or any Award to comply with or be exempt from Section 409A of the Code. 

  
 14 

 (k)    Clawback/Recovery. All Awards granted under
this Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are
listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board
determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of an event constituting Cause. No recovery of
compensation under such a clawback policy will be an event giving rise to a right to voluntary terminate employment upon “resignation” for “good reason” or for a “constructive termination” or any similar term under any
plan of or agreement with the Company. 
 (l)    Not Benefit Plan Compensation. Payments and other
benefits received by a Participant under an Award made pursuant to this Plan will not be deemed a part of Participant’s compensation for purposes of determining the Participant’s benefits under any other benefit plans or arrangements
provided by the Company or an Affiliate, except where the Board expressly provides otherwise in writing. 

9.    ADJUSTMENTS UPON CHANGES IN COMMON
STOCK; OTHER CORPORATE EVENTS. 

(a)    Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will
appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to this Plan pursuant to Section 3(a); and (ii) the class(es) and number of securities and price per share of
Common Stock subject to outstanding Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive. 

(b)    Dissolution. Except as otherwise provided in the Award Agreement, in the event of a Dissolution
of the Company, all outstanding Awards (other than Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion
of such Dissolution, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Award is
providing Continuous Service; provided, however, that the Board may, in its sole discretion, cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Awards have not
previously expired or terminated) before the Dissolution is completed but contingent on its completion. 

(c)    Transaction. The following provisions will apply to Awards in the event of a Transaction unless
otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time of grant of an Award. In the event
of a Transaction, then, notwithstanding any other provision of this Plan, the Board may take one or more of the 

  
 15 

 
following actions with respect to Awards, contingent upon the closing or completion of the Transaction: 

(i)    arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring
corporation’s parent company) to assume or continue the Award or to substitute a similar stock award for the Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to
the Transaction); 
 (ii)    arrange for the assignment of any reacquisition or repurchase rights held by the
Company in respect of Common Stock issued pursuant to the Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii)    accelerate the vesting, in whole or in part, of the Award (and, if applicable, the time at which the
Award may be exercised) to a date prior to the effective time of such Transaction as the Board determines (or, if the Board does not determine such a date, to the date that is five days prior to the effective date of the Transaction), with such
Award terminating if not exercised (if applicable) at or prior to the effective time of the Transaction; provided, however, that the Board may require Participants to complete and deliver to the Company a notice of exercise before the effective date
of a Transaction, which exercise is contingent upon the effectiveness of such Transaction; 
 (iv)    arrange
for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Award; 

(v)    cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the
effective time of the Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and 

(vi)    make a payment, in such form as may be determined by the Board equal to the excess, if any, of
(A) the value of the property the Participant would have received upon the exercise of the Award immediately prior to the effective time of the Transaction, over (B) any exercise price payable by such holder in connection with such
exercise. For clarity, this payment may be $0 if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of the
Company’s Common Stock in connection with the Transaction is delayed as a result of escrows, earn outs, holdbacks or other contingencies. 
 The Board
need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants. The Board may take different actions with respect to the vested and unvested portions of an Award. 

(d)    Change in Control. An Award may be subject to additional acceleration of vesting and
exercisability upon or after a Change in Control as may be provided in the Award Agreement for such Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such
provision, no such acceleration will automatically occur. 

  
 16 

 10.    TERMINATION OR
SUSPENSION OF THIS PLAN. The Board may suspend or terminate this Plan at any time. No Awards may be granted under this Plan while this Plan is suspended or after it is
terminated. 
 11.    EFFECTIVE DATE OF THIS
PLAN. This Plan will come into existence on the Effective Date. 

12.    CHOICE OF LAW. The laws of the State of
Delaware will govern all questions concerning the construction, validity and interpretation of this Plan, without regard to that state’s conflict of laws rules. 

13.    DEFINITIONS. As used in this Plan, the following definitions will
apply to the capitalized terms indicated below: 
 (a)    “Affiliate” means, at the time
of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 of the Securities Act. The Board will have the authority to determine the time or times at which “parent” or
“subsidiary” status is determined within the foregoing definition.

Restricted Stock Unit Award, a Performance Stock Award, a Performance Cash Award or an Other Stock Award.

structure or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the
conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment. 

(f)    “Cause” shall have the meaning ascribed to such term in any
written agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s

unauthorized use or disclosure of the Company’s confidential information or 

  
 17 

 
trade secrets; or (v) such Participant’s gross misconduct. The determination that a termination of the Participant’s Continuous Service is either for Cause or without Cause shall
be made by the Company, in its sole discretion. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant shall have no
effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose. 

(g)    “Change in Control” unless otherwise defined in the applicable Award Agreement or
other written agreement approved by the Board or the Committee means the occurrence of any of the following: 

(i)    the acquisition (including through purchase, reorganization, merger, consolidation or similar transaction),
directly or indirectly, in one or more transactions by a person of beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities representing 50% or more of the combined voting
power of the securities of the Company entitled to vote generally in the election of directors of the Board, calculated on a fully diluted basis after giving effect to such acquisition; 

(ii)    an election of persons to the Board that causes two-thirds of the
Board to consist of persons other than (i) members of the Board on the Effective Date and (ii) persons who were nominated for election as members of the Board at a time when two-thirds of the Board
consisted of persons who were members of the Board on the Effective Date; provided that any person nominated for election by a Board at least two-thirds of which consisted of persons
described in clauses (i) or (ii) or by persons who were themselves nominated by such Board shall be deemed to have been nominated by a Board consisting of persons described in clause (i); or 

(iii)    the sale or other disposition, directly or indirectly, of all or substantially all of the assets of the
Company and its Subsidiaries, taken as a whole, to any person; 
 provided, however, that a Change in Control shall be

voting securities of the Company or any of its Affiliates or any rights to acquire voting securities of the Company or any of its Affiliates which are convertible into voting securities.    For purposes of this definition of
Change in Control, a “person” means any individual, entity (including any employee benefit plan or any trust for an employee benefit plan) or group (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act,
or any successor provision).

including an advisor, who is (i) engaged by the Company or an Affiliate to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is
compensated for such services. However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of this Plan. Notwithstanding the
foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s
securities to such person. 
 (l)    “Continuous Service” means that the
Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as
an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not
terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such
Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s
sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave,
or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in
the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law. 

(m)    “Corporate Transaction” means the consummation, in a single transaction or in a
series of related transactions, of any one or more of the following events: 
 (i)    a sale or
other disposition of all or substantially all, as determined by the Board, in its sole discretion, of the consolidated assets of the Company and its Subsidiaries; 

(ii)    a sale or other disposition of more than 50% of the outstanding securities of the Company; 

(iii)    a merger, consolidation or similar transaction following which the Company is not the surviving
corporation; or 
 (iv)    a merger, consolidation or similar transaction following which the Company is the
surviving corporation but the shares of Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property,
whether in the form of securities, cash or otherwise. 

  
 19 

 (n)    “Director” means a member of the
Board. Directors are not eligible to receive Awards under this Plan with respect to their service in such capacity.

(p)    “Dissolution” means when the Company, after having executed a certificate of
dissolution with the State of Delaware (or other applicable state), has completely wound up its affairs. Conversion of the Company into a Limited Liability Company (or any other pass-through entity) will not be considered a
“Dissolution” for purposes of this Plan. 
 (q)    “Effective Date” means
July 2, 2021. 
 (r)    “Employee” means any person employed by the Company or an
Affiliate. However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of this Plan. 

(s)    “Entity” means a corporation, partnership, limited liability company or other
entity. 
 (t)    “Exchange Act” means the Securities Exchange Act of 1934, as amended,
and the rules and regulations promulgated thereunder.

shall be the closing price reported or quoted on the NASDAQ Stock Market for the Common Stock on such date, or if the Common Stock shall not have been reported or quoted on such date and the Common Stock is listed on the TSX, the Fair Market Value
of a share of Common Stock shall be the United States dollar equivalent (determined by using the closing $CAN to $US exchange rate published by the Bank of Canada on the applicable date) of the closing price reported or quoted on the TSX for the
Common Stock on such date, or if the Common Stock shall not have been reported or quoted on such date on either the NASDAQ Stock Market or the TSX, the Fair Market Value of a share of Common Stock shall be the closing price reported or quoted on the

closing price reported or quoted on the TSX for the Common Stock on such date, or if the Common Stock shall not have been reported or quoted on such date, on the first day prior thereto on which the Common Stock was reported or quoted on the TSX, in
each case as reported in a source the Board or the Committee deems reliable; 
 (iii)    if the Common Stock is
not listed on the NASDAQ Stock Market or the TSX, the Fair Market Value of a share of Common Stock shall be the closing price reported for the Common Stock on such date: (i) as reported on the principal national securities exchange in the

the fair market value of the Common Stock as determined by the Board or the Committee in good faith in whatever manner it considers appropriate taking into account the requirements of Section 409A or Section 422 of the Code, as applicable.

operational unit, business segment or administrative department of the Company or any Affiliate) performance under one or more of the measures described above and may be measured relative to the performance of other corporations (or an affiliate,
subsidiary, division, other operational unit, business segment or administrative department of another corporation or its affiliates). Any goal may be expressed as a dollar figure, on a percentage basis (if applicable) or on a per share basis, and
goals may be either absolute, relative to a selected peer group or index, or a combination of both. The Committee may: (A) designate additional business criteria on which the Performance Criteria may be based or (B) adjust, modify or amend

measures used in Performance Criteria set under the Plan shall be determined in accordance with generally accepted accounting principles (“GAAP”) and in a manner consistent with the methods used in the Company’s regular
reports on Forms 10-K and 10-Q, without regard to any of the following unless otherwise determined by the Committee: (1) all items of gain, loss or expense for the
fiscal year or other applicable performance period that are related to special, unusual or non-recurring items, events or circumstances affecting the Company (or Affiliate, division, other operational unit,
business segment or administrative department of the Company or any Affiliate) or the financial statements of the Company (or Affiliate, division, other operational unit, business segment or administrative department of the Company or any
Affiliate); (2) all items of gain, loss or expense for the fiscal year or other applicable performance period that are related to (i) the disposal of a business or discontinued operations or (ii) the operations of any business acquired by
the Company (or Affiliate, division, other operational unit, business segment or administrative department of the Company or any Affiliate) during the fiscal year or other applicable performance period; and (3) all items of gain, loss or
expense for the fiscal year or other applicable performance period that are related to changes in accounting principles or to changes in applicable law or regulations. To the extent any Performance Criteria are expressed using any measures that
require deviations from GAAP, such deviations shall be at the discretion of the Committee as exercised at the time the Performance Criteria are set. 

(hh)    “Performance Goals” means, for a Performance Period, the one or more goals

Company, or the financial statements of the Company in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions; or (c) in view of the Company’s Independent Directors or the
Committee’s assessment of the business strategy of the Company, performance of comparable organizations, economic and business conditions, and any other circumstances deemed relevant. Specifically, the Company’s Independent Directors or
the Committee are authorized to make adjustment in the method of calculating attainment of Performance Goals and objectives for a Performance Period as follows: (i) to exclude the dilutive effects of acquisitions or joint ventures; (ii) to
assume that any business divested by the Company achieved performance objectives at targeted levels during the balance of a Performance Period following such divestiture; and (iii) to exclude the effect of any change in the outstanding shares
of common stock of the Company by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar
corporate change, or any distributions to common stockholders other than regular cash dividends. In addition, the Company’s Independent Directors or the Committee are authorized to make adjustment in the method of calculating attainment of
Performance Goals and objectives for a Performance Period as follows: (i) to exclude restructuring and/or other nonrecurring charges; (ii) to exclude exchange rate effects, as applicable, for
non-U.S. dollar denominated net sales and operating earnings; (iii) to exclude the effects of changes to generally accepted accounting standards required by the Financial Accounting Standards Board;
(iv) to exclude the effects of any items that are “unusual” in nature or occur “infrequently” as determined under generally accepted accounting principles; (v) to exclude the effects to any statutory adjustments to
corporate tax rates; and (vi) to make other appropriate adjustments selected by the Company’s Independent Directors or the Committee. 

(ii)    “Performance Period” means the period of time selected by a majority of the
Company’s Independent Directors or the Committee over which the attainment of one or more Performance Goals will be measured for the purpose of determining a Participant’s right to and the payment of an Award. Performance Periods may
be of varying and overlapping duration, at the sole discretion of a majority of the Company’s Independent Directors or the Committee. 

(jj)    “Performance Stock Award” means an Award granted under the terms and conditions of

 ATTACHMENT I 

HELIUS MEDICAL TECHNOLOGIES, INC. 

OPTION AGREEMENT 

(2021 INDUCEMENT PLAN) 

(NONSTATUTORY STOCK OPTION) 

Pursuant to your Stock Option Grant Notice (the “Grant Notice”) and this Option Agreement (this
“Agreement”), Helius Medical Technologies, Inc., a Delaware corporation (the “Company”) has granted you an option under the Helius Medical Technologies, Inc. 2021 Inducement Plan (the
“Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. The option is granted to you effective as of the date of
grant set forth in the Grant Notice (the “Date of Grant”). The option is granted in compliance with Nasdaq Listing Rule 5635(c)(4) as a material inducement to you entering into employment with the Company. If there
is any conflict between the terms in this Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but defined in the Plan will have the same definitions as
in the Plan. 
 The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1.    VESTING. Subject to the provisions contained herein, your option will vest as
provided in your Grant Notice. Vesting will cease upon the termination of your Continuous Service (except as may otherwise be provided in the vesting section of the Grant Notice). 

2.    NUMBER OF SHARES AND EXERCISE
PRICE. The number of shares of Common Stock subject to your option and your exercise price per share in your Grant Notice will be adjusted for Capitalization Adjustments. 

3.    EXERCISE RESTRICTION FOR NON-EXEMPT EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided in the Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the
Date of Grant, even if you have already been an employee for more than six (6) months. Consistent with the provisions of the Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month
anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in which your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your
“retirement” (as defined in the Company’s benefit plans). 
 4.    METHOD
OF PAYMENT. You must pay the full amount of the exercise price for the shares you wish to exercise. You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or
in any other manner permitted by the Grant Notice, which may include one or more of the following: 

  
 3 

 (a)    Provided that at the time of exercise the Common Stock is
publicly traded, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of
irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”. 

(b)    Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company
(either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of
exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form
approved by the Company. You may not exercise your option by delivery to the Company of Common Stock if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

(c)    Subject to the consent of the Company at the time of exercise, by a “net exercise” arrangement
pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price. You must pay
any remaining balance of the aggregate exercise price not satisfied by the “net exercise” in cash or other permitted form of payment. Shares of Common Stock will no longer be outstanding under your option and will not be exercisable
thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding obligations. 

5.    WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock. 
 6.    SECURITIES LAW COMPLIANCE. In no
event may you exercise your option unless the shares of Common Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be
exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with all other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines
that such exercise would not be in material compliance with such laws and regulations (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

7.    TERM. You may not exercise your option before the Date of Grant or after the
expiration of the option’s term. The term of your option expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following: 

(a)    immediately upon the termination of your Continuous Service for Cause; 

(b)    immediately upon the termination of your Continuous Service for any reason to the extent the shares subject
to your option have not vested on or prior to such termination of your Continuous Service (except as may otherwise be provided in the vesting section of the Grant Notice); 

  
 4 

 (c)    three (3) months after the termination of your
Continuous Service for any reason other than Cause (except as may otherwise be provided in the vesting section of the Grant Notice), your Disability or your death (except as otherwise provided in Section 7(e) below); provided,
however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above regarding “Securities Law Compliance,” your option will not expire until
the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; provided further, if during any part of such three (3) month period,
the sale of any Common Stock received upon exercise of your option would violate the Company’s insider trading policy, then your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service during which the sale of the Common Stock received upon exercise of your option would not be in violation of the Company’s insider trading
policy. Notwithstanding the foregoing, if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant, and (iii) you have
vested in a portion of your option at the time of your termination of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant, and
(B) the date that is three (3) months after the termination of your Continuous Service (or such other date that may otherwise be provided in the vesting section of the Grant Notice), and (y) the Expiration Date; 

(d)    twelve (12) months after the termination of your Continuous Service due to your Disability (except as
otherwise provided in Section 7(d)) below; 
 (e)    twelve (12) months after your death if you die
either during your Continuous Service or within three (3) months after your Continuous Service terminates for any reason other than Cause; 

(f)    the Expiration Date indicated in the Grant Notice; or 

(g)    the day before the tenth (10th) anniversary of the Date
of Grant. 
 8.    EXERCISE. 

(a)    You may exercise the vested portion of your option (and the unvested portion of your option if your Grant
Notice so permits) during its term by (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price
and any applicable withholding taxes to the Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require. 

(b)    By exercising the Grant Notice you agree that, as a condition to any exercise of your option, the Company
may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising 

  
 5 

 
by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or
(iii) the disposition of shares of Common Stock acquired upon such exercise. 

9.    TRANSFERABILITY. Except as otherwise provided in this Section 9, your option
is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. 

(a)    Certain Trusts. Upon receiving written permission from the Board or its duly authorized designee,
you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust. You and the trustee must enter into
transfer and other agreements required by the Company. 
 (b)    Domestic Relations Orders. Upon
receiving written permission from the Board or its duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of
a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the
Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this option with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required
information is contained within the domestic relations order or marital settlement agreement. 

(c)    Beneficiary Designation. Upon receiving written permission from the Board or its duly authorized
designee, you may, by delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to
exercise this option and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate will be entitled to exercise this option and receive, on
behalf of your estate, the Common Stock or other consideration resulting from such exercise. 

10.    OPTION NOT A SERVICE
CONTRACT. Your option is not an employment or service contract, and nothing in your option will be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate,
or of the Company or an Affiliate to continue your employment. In addition, nothing in your option will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue any relationship
that you might have as a Director or Consultant for the Company or an Affiliate. 
 11.    WITHHOLDING
OBLIGATIONS. 
 (a)    At the time you exercise your option, in whole or in part, and at any
time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “same day sale” pursuant to a
program developed under Regulation T as promulgated 

  
 6 

 
by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an
Affiliate, if any, which arise in connection with the exercise of your option. 
 (b)    Upon your request and
subject to approval by the Company, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole
shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the maximum amount of tax permitted to be withheld by law (or such lower amount as may be necessary to avoid classification of
your option as a liability for financial accounting purposes). Shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such
exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c)    You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate
are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company will have no obligation to issue a certificate for such shares of Common Stock or release such shares of
Common Stock from any escrow provided for herein, if applicable, unless such obligations are satisfied. 

12.    TAX CONSEQUENCES. You hereby agree that the Company does
not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related
to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in the Grant Notice is at least equal
to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. 

13.    NOTICES. Any notices provided for in your option or the Plan will be given in writing
(including electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the
last address you provided to the Company. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the Plan by
electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained
by the Company or another third party designated by the Company. 
 14.    GOVERNING
PLAN DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and
regulations, which may from time to time be promulgated and adopted pursuant to the Plan. If there is any conflict between the provisions of your option 

  
 7 

 
and those of the Plan, the provisions of the Plan will control. In addition, your option (and any compensation paid or shares issued under your option) is subject to recoupment in accordance
with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law. 

15.    OTHER DOCUMENTS. You hereby acknowledge receipt of
and the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s policy permitting
certain individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

16.    EFFECT ON OTHER EMPLOYEE
BENEFIT PLANS. The value of this option will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan sponsored by the
Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans. 

17.    VOTING RIGHTS. You will not have voting or any other rights as a
