2021 EQUITY INCENTIVE PLAN

 

RESTRICTED STOCK UNIT AGREEMENT

 

1. Grant. The Company
hereby grants to the individual (the “Participant”) named in the Notice of Restricted Stock Unit Grant (the
“Notice of Grant”) an Award of Restricted Stock Units under the Momentus Inc. 2021 Equity Incentive Plan (the
“Plan”), subject to all of the terms and conditions in the Notice of Grant, this Restricted Stock Unit Agreement
(the “Award Agreement”) and the Plan, which is incorporated herein by reference. [If there is a conflict between
the terms and conditions of the Plan and the terms and conditions of this Award Agreement, the terms and conditions of the Plan will prevail.]

 

2. Company’s Obligation
to Pay. Each Restricted Stock Unit represents the right to receive a Share on the date it vests. Unless and until the Restricted Stock
Units will have vested in the manner set forth in Section 3, Participant will have no right to receive Shares pursuant to any such Restricted
Stock Units. Prior to actual payment of any vested Restricted Stock Units, such Restricted Stock Units will represent an unsecured obligation
of the Company. Any Restricted Stock Units that vest in accordance with Section 3 will be settled by delivery of whole Shares as set forth
herein to Participant (or in the event of Participant’s death, to his or her estate), subject to Participant satisfying any Tax-Related
Items as set forth in Section 7. Subject to the provisions of Section 4, such vested Restricted Stock Units will be settled by delivery
of whole Shares as soon as practicable after vesting, but in each such case within the period ending no later than the date that is two
and one-half (21⁄2) months from the end of the Company’s tax year that includes the vesting date. In no event will Participant
be permitted, directly or indirectly, to specify the taxable year in which Shares will be issued upon payment of any Restricted Stock
Units under this Award Agreement.

 

3. Vesting Schedule.
The Restricted Stock Units awarded by this Award Agreement will vest in accordance with the vesting provisions set forth in the Notice
of Grant. [Restricted Stock Units scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in accordance
with any of the provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from the Date of
Grant until the date such vesting occurs.] Service Provider status for purposes of this Award will end on the day that Participant is
no longer actively providing services as an Employee, Director, or Independent Contractor and will not be extended by any notice period
or “garden leave” that may be required contractually or under Applicable Laws. Notwithstanding the foregoing, the Administrator
(or any delegate) shall have the sole and absolute discretion to determine when Participant is no longer providing active service for
purposes of Service Provider status and participation in the Plan.

 

4. Administrator Discretion.
Notwithstanding anything in the Plan or this Award Agreement to the contrary, if the vesting of the balance, or some lesser portion of
the balance, of the Restricted Stock Units is accelerated in connection with Participant’s termination as a Service Provider (provided
that such termination is a “separation from service” within the meaning of Code Section 409A, as determined by the Company),
other than due to death, and if (x) Participant is a “specified employee” within the meaning of Code Section 409A at the time
of such termination as a Service Provider and (y) the payment of such accelerated Restricted Stock Units will result in the imposition
of additional tax under Code Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination
as a Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and
one (1) day following the date of Participant’s termination as a Service Provider, unless the Participant dies following his or
her termination as a Service Provider, in which case, the Restricted Stock Units will be settled in Shares to the Participant’s
estate as soon as practicable following his or her death. It is the intent of this Award Agreement that it and all payments and benefits
hereunder be exempt from, or comply with, the requirements of Code Section 409A so that none of the Restricted Stock Units provided under
this Award Agreement or Shares issuable thereunder will be subject to the additional tax imposed under Code Section 409A, and any ambiguities
herein will be interpreted to be so exempt or so comply. Each payment payable under this Award Agreement is intended to constitute a separate
payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). For purposes of this Award Agreement, “Code Section 409A”
means Section 409A of the Code, and any final U.S. Treasury Regulations and U.S. Internal Revenue Service guidance thereunder, as each
may be amended from time to time.

 

    2

     

    

 

5. Forfeiture upon Termination
of Status as a Service Provider. Except as otherwise provided in the Notice of Grant, any Restricted Stock Units that have not vested
will be forfeited and will return to the Plan on the date that is thirty (30) days following the termination of Participant’s status
as a Service Provider.

 

6. Death of Participant.
Any distribution or delivery to be made to Participant under this Award Agreement will, if Participant is then deceased, be made to Participant’s
designated beneficiary, if so allowed by the Administrator in its sole discretion, or if no beneficiary survives Participant, the administrator
or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as
transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any Applicable
Laws or regulations pertaining to said transfer.

 

7. Withholding of Taxes.
Regardless of any action the Company or Participant’s employer (the “Employer”) takes with respect to
any or all applicable national, local, or other tax or social contribution, withholding, required deductions, or other payments, if any,
that arise upon the grant or vesting of the Restricted Stock Units or the holding or subsequent sale of Shares, and the receipt of dividends,
if any, or otherwise in connection with the Restricted Stock Units or the Shares (“Tax-Related Items”), Participant
acknowledges and agrees that the ultimate liability for all Tax-Related Items legally due by Participant is and remains Participant’s
responsibility and may exceed any amount actually withheld by the Company or the Employer. Participant further acknowledges and agrees
that Participant is solely responsible for filing all relevant documentation that may be required in relation to the Restricted Stock
Units or any Tax-Related Items (other than filings or documentation that is the specific obligation of the Company, an Affiliate or Employer
pursuant to Applicable Laws) such as but not limited to personal income tax returns or reporting statements in relation to the grant,
vesting or payment of the Restricted Stock Units, the holding of Shares or any bank or brokerage account, the subsequent sale of Shares,
and the receipt of any dividends. Participant further acknowledges 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 Stock Units, including the grant or vesting
of the Restricted Stock Units, the subsequent sale of Shares acquired under the Plan, and the receipt of dividends, if any; and (b) do
not commit to and are under no obligation to structure the terms of the Restricted Stock Units or any aspect of the Restricted Stock Units
to reduce or eliminate Participant’s liability for Tax-Related Items, or achieve any particular tax result. Participant also understands
that Applicable Laws may require varying Share or Restricted Stock Unit valuation methods for purposes of calculating Tax-Related Items,
and the Company assumes no responsibility or liability in relation to any such valuation or for any calculation or reporting of income
or Tax-Related Items that may be required of Participant under Applicable Laws. Further, if Participant has become subject to tax in more
than one jurisdiction between the date of grant and the date of any relevant taxable event, 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. Notwithstanding any contrary provision of this Award Agreement, no certificate representing the Shares will be issued to
Participant, unless and until satisfactory arrangements (as determined by the Administrator) will have been made by Participant with respect
to the payment of any Tax-Related Items which the Company determines must be withheld with respect to such Shares.

 

As a condition to the grant
and vesting of the Restricted Stock Units and as set forth in Section 16 of the Plan, Participant hereby agrees to make adequate provision
for the satisfaction of (and will indemnify the Company and any Affiliate for) any Tax-Related Items. In this regard, Participant authorizes
the Company and/or the Employer or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related
Items by one or a combination of the following: (i) by receipt of a cash payment from Participant; (ii) by withholding from Participant’s
wages or other cash compensation paid to Participant by the Company or the Employer; (iii) withholding Shares that otherwise would be
issued to Participant upon payment of the vested Restricted Stock Units (provided that amounts withheld shall not exceed the amount necessary
to satisfy the Company’s minimum tax withholding obligations); (iv) by withholding from proceeds of the sale of Shares acquired
upon payment of the vested Restricted Stock Units through a voluntary sale or a mandatory sale arranged by the Company (on Participant’s
behalf pursuant to this authorization), or (v) by any other arrangement approved by the Committee. Notwithstanding the foregoing, if Participant
is subject to Section 16 of the Exchange Act, Participant’s obligations with respect to all Tax-Related Items shall be satisfied
by the Company withholding Shares that otherwise would be issued to Participant upon payment of the vested Restricted Stock Units; provided
that amounts withheld shall not exceed the amount necessary to satisfy the Company’s minimum tax withholding obligations. Any Shares
withheld pursuant to this Section 7 shall be valued based on the Fair Market Value as of the date the withholding obligations are satisfied.
Furthermore, Participant agrees to pay the Company, any Affiliate or Employer any Tax-Related Items that cannot be satisfied by the foregoing
methods.

 

    3

     

    

 

8. Rights as Stockholder.
Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of
the Company in respect of any Shares deliverable hereunder unless and until such Shares will have been issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company). After such issuance, Participant will have all
the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares,
but prior to such issuance, Participant will not have any rights to dividends and/or distributions on such Shares.

 

9. No Guarantee of Continued
Service or Grants. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE
HEREOF SHALL OCCUR ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE EMPLOYER OR CONTRACTING ENTITY (AS APPLICABLE) AND NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS AWARD OF RESTRICTED STOCK UNITS OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER
ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR
AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE EMPLOYER OR THE COMPANY (OR ANY AFFILIATE)
TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE, SUBJECT TO APPLICABLE LAWS.

 

Participant also acknowledges
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; (b) the grant of Restricted Stock Units is voluntary and occasional and does not create
any contractual or other right to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units even
if Restricted Stock Units have been granted repeatedly in the past; (c) all decisions with respect to future awards of Restricted Stock
Units, if any, will be at the sole discretion of the Company; (d) Participant’s participation in the Plan is voluntary; (e) the
Restricted Stock Units and the Shares subject to the Restricted Stock Units are extraordinary items that do not constitute regular compensation
for services rendered to the Company or the Employer, and that are outside the scope of Participant’s employment contract, if any;
(f) the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any pension rights or
compensation; (g) the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not part of normal or expected compensation
or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal,
or end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments and in no event
should be considered as compensation for, or relating in any way to, past services for the Company or the Employer, subject to Applicable
Laws.

 

10. Address for Notices.
Any notice to be given to the Company under the terms of this Award Agreement will be addressed to the Company, in care of its Secretary
at Momentus Inc., 3901 N. First Street, San Jose, CA 95134, or at such other address as the Company may hereafter designate in writing.

 

11. Grant is Not Transferable.
Except to the limited extent provided in Section 6, this grant and the rights and privileges conferred hereby may not be transferred,
assigned, pledged or hypothecated in any way (whether by operation of Applicable Laws or otherwise) and may not be subject to sale under
execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant,
or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant
and the rights and privileges conferred hereby immediately will become null and void.

 

12. Binding Agreement.
Subject to the limitation on the transferability of this grant contained herein, this Award Agreement will be binding upon and inure to
the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

 

    4

     

    

 

13. Additional Conditions
to Issuance of Stock and Imposition of Other Requirements. If at any time the Company will determine, in its discretion, that the
listing, registration, qualification or compliance of the Shares upon or with any securities exchange or under any Applicable Laws, the
tax code and related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition
to the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such listing,
registration, qualification, compliance, consent or approval will have been completed, effected or obtained free of any conditions not
acceptable to the Company. Where the Company determines that the delivery of any Shares will violate any state, federal or foreign securities
or exchange laws or other Applicable Laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates
that the delivery of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements
of any Applicable Laws or securities exchange and to obtain any such consent or approval of any such governmental authority or securities
exchange. The Company shall not be obligated to issue any Shares pursuant to the Restricted Stock Units at any time if the issuance of
Shares violates or is not in compliance with any Applicable Laws.

 

Furthermore, the Company reserves
the right to impose other requirements on Participant’s participation in the Plan, on the Restricted Stock Units and on any Shares
acquired under the Plan, to the extent the Company determines it is necessary or advisable in order to comply with any Applicable Laws
or facilitate the administration of the Plan, and to require Participant to sign any additional agreements or undertakings that may be
necessary to accomplish the foregoing. Furthermore, Participant understands that the Applicable Laws of the country in which he or she
is resident at the time of grant or vesting of the Restricted Stock Units or the holding or disposition of Shares (including any rules
or regulations governing securities, foreign exchange, tax, labor or other matters) may restrict or prevent the issuance of Shares or
may subject Participant to additional procedural or regulatory requirements he or she is solely responsible for and will have to independently
fulfill in relation to the Restricted Stock Units or the Shares. [Notwithstanding any provision herein, the Restricted Stock Units and
any Shares shall be subject to any special terms and conditions or disclosures as set forth in any addendum for Participant’s country
(the “Country-Specific Addendum,” which forms part this Award Agreement)]. Participant also understands and
agrees that if he or she works, resides, moves to, or otherwise is or becomes subject to Applicable Laws or company policies of another
jurisdiction at any time, certain country-specific notices, disclaimers and/or terms and conditions may apply to him or her as from the
date of grant, unless otherwise determined by the Company in its sole discretion.

 

14. Lock-Up Agreement.
If so requested by the Company in connection with a transaction pursuant to which the securities of the Company will be exchanged for
securities of a company (or any successor or parent thereof) registered under the Securities Act of 1933, as amended (the “Securities
Act”), including, without limitation, through a transaction with a publicly-listed blank check company then registered under
the Securities Act (a “SPAC Transaction”), Participant hereby agrees (i) not to offer, pledge, sell, contract
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 without the prior written consent of the Company for a period of 180 days from the date of the consummation of the
transaction in which the securities of the Company became a Listed Security (as defined below), and (ii) to execute an agreement reflecting
the foregoing. For purposes of this Section, “Listed Security” means any security of the Company that is listed
or approved for listing on a national securities exchange (including, without limitation, pursuant to a SPAC Transaction) or designated
or approved for designation as a national market system security on an interdealer quotation system by the Financial Industry Regulatory
Authority (or any successor thereto).

 

15. Plan Governs. This
Award Agreement is subject to all terms and provisions of the Plan. If there is a conflict between one or more provisions of this Award
Agreement and one or more provisions of the Plan, the provisions of the Plan will govern. Capitalized terms used and not defined in this
Award Agreement and the Notice of Grant will have the meaning set forth in the Plan.

 

16. Administrator Authority.
The Administrator will have the power to interpret the Plan and this Award Agreement and to adopt such rules for the administration, interpretation
and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the
determination regarding whether any Restricted Stock Units have vested). All actions taken, and all interpretations and determinations
made, by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No
member of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect
to the Plan or this Award Agreement.

and maintained by the Company or a third party designated by the Company, and consents to the electronic delivery of the Award Agreement,
the Plan, account statements, Plan prospectuses, and all other documents, communications, or information related to the Award and current

if Participant contacts the Company by telephone, through a postal service, or electronic mail to Stock Administration.

 

18. Translation. If
Participant has received this Award Agreement, including appendices, or any other document related to the Plan translated into a language
other than English, and the meaning of the translated version is different than the English version, the English version will control.

 

19. Captions. Captions
provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Award Agreement.

 

20. Agreement Severable.
If any provision in this Award Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity
or unenforceability will not be construed to have any effect on, the remaining provisions of this Award Agreement.

 

21. Modifications to the
Award Agreement. This Award Agreement constitutes the entire understanding of the parties on the subjects covered. Participant expressly
warrants that he or she is not accepting this Award Agreement in reliance on any promises, representations, or inducements other than
those contained herein. Modifications to this Award Agreement or the Plan can be made only in an express written contract executed by
a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Award Agreement, the Company reserves
the right to revise this Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant,
to comply with Code Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Code Section 409A
in connection to this Award of Restricted Stock Units.

 

22. Data Privacy.
Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s
Personal Data (as described below) by and among, as applicable, the Company, any Affiliate or third parties as may be selected by the
Company for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. Participant
understands that refusal or withdrawal of consent will affect Participant’s ability to participate in the Plan; without providing
consent, Participant will not be able to participate in the Plan or realize benefits (if any) from the Restricted Stock Units.

 

Participant understands
that the Company and any Affiliate or designated third parties may hold personal information about Participant, including, but not limited
to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number,
salary, nationality, job title, any shares of stock or directorships held in the Company or any Affiliate, details of all Restricted Stock
Units or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Personal
Data”). Participant understands that Personal Data may be transferred to any Affiliate or third parties assisting in the implementation,
administration and management of the Plan, that these recipients may be located in the United States, Participant’s country (if
different than the United States), or elsewhere, and that the recipient’s country may have different data privacy laws and protections
than Participant’s country. In particular, the Company may transfer Personal Data to the broker or stock plan administrator assisting
with the Plan, to its legal counsel and tax/accounting advisor, and to the Affiliate or entity that is Participant’s employer and
its payroll provider.

 

    6

     

    

 

Participant should also
refer to any data privacy policy implemented by the Company (which will be available to Participant separately and may be updated from
time to time) for more information regarding the collection, use, storage, and transfer of Participant’s Personal Data.

 

23. Foreign Exchange Fluctuations
and Restrictions. Participant understands and agrees that the future value of the underlying Shares is unknown and cannot be predicted
with certainty and may decrease. Participant also understands that neither the Company, nor any Affiliate is responsible for any foreign
exchange fluctuation between local currency and the United States Dollar or the selection by the Company or any Affiliate in its sole
discretion of an applicable foreign currency exchange rate that may affect the value of the Restricted Stock Units or Shares received
(or the calculation of income or Tax-Related Items thereunder). Participant understands and agrees that any cross-border remittance made
to transfer proceeds received upon the sale of Shares must be made through a locally authorized financial institution or registered foreign
exchange agency and may require the Participant to provide such entity with certain information regarding the transaction.

 

24. Amendment, Suspension
or Termination of the Plan. By accepting this Award, Participant expressly warrants that he or she has received an Award of Restricted
Stock Units under the Plan, and has received, read and understood a description of the Plan. Participant understands that the Plan is
discretionary in nature and may be amended, suspended or terminated by the Company at any time.

 

25. Governing Law and
Venue. This Award Agreement will be governed by the laws of the State of Delaware, without giving effect to the conflict of law principles
thereof. For purposes of litigating any dispute that arises under this Award of Restricted Stock Units or this Award Agreement, the parties
hereby submit to and consent to the jurisdiction of the State of Delaware, and agree that such litigation will be conducted in the courts
of New Castle County, Delaware, or the federal courts for the United States for the District of Delaware, and no other courts.

[Country-Specific Addendum

 

This Addendum includes additional country-specific
notices, disclaimers, and/or terms and conditions that apply to individuals who are working or residing in the countries listed below,
if any, and that may be material to Participant’s participation in the Plan. Such notices, disclaimers, and/or terms and conditions
may also apply, as from the date of grant, if Participant moves to or otherwise is or becomes subject to the Applicable Laws or company
policies of any country listed below. However, because foreign exchange regulations and other local laws are subject to frequent change,
Participant is advised to seek advice from his or her own personal legal and tax advisor prior to accepting the Restricted Stock Units
or holding or selling Shares acquired under the Plan. The Company is not providing any tax, legal or financial advice, nor is the Company
making any recommendations regarding Participant’s acceptance of the Restricted Stock Units or participation in the Plan. Unless
otherwise noted below, capitalized terms shall have the same meaning assigned to them under the Plan, the Notice of Restricted Stock Unit
Grant and the Award Agreement. This Addendum forms part of the Award Agreement and should be read in conjunction with the Award Agreement
and the Plan.

 

Securities Law Notice: Unless otherwise
noted, neither the Company nor the Shares are registered with any local stock exchange or under the control of any local securities regulator
outside the United States. The Award Agreement (of which this Addendum is a part), the Notice of Restricted Stock Unit Grant, the Plan,
and any other communications or materials that you may receive regarding participation in the Plan do not constitute advertising or an
offering of securities outside the United States, and the issuance of securities described in any Plan-related documents is not intended
for public offering or circulation in your jurisdiction.]

 

 

8Exhibit 10.8

 

MOMENTUS INC.

 

2021 EMPLOYEE STOCK
PURCHASE PLAN

 

1.  General;
Purpose.

 

(a)  Purpose.
The Plan provides a means by which Eligible Employees and/or Eligible Service Providers of either the Company or a Designated Company
may be given an opportunity to purchase shares of Common Stock. The Plan permits the Company to grant a series of Purchase Rights to Eligible
Employees and/or Eligible Service Providers. The Company, by means of the Plan, seeks to retain and assist its Related Corporations or
Affiliates in retaining the services of such Eligible Employees and Eligible Service Providers, to secure and retain the services of new
Eligible Employees and Eligible Service Providers and to provide incentives for such persons to exert maximum efforts for the success
of the Company and its Related Corporations and Affiliates.

 

(b)  Qualified
and Non-Qualified Offerings Permitted. The Plan includes two components: a 423 Component and a Non-423 Component. The Company
intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as an Employee Stock Purchase Plan.
The provisions of the 423 Component, accordingly, will be construed in a manner that is consistent with the requirements of Section 423
of the Code, including without limitation, to extend and limit Plan participation in a uniform and non-discriminating basis. In addition,
this Plan authorizes grants of Purchase Rights under the Non-423 Component that do not meet the requirements of an Employee Stock
Purchase Plan. Except as otherwise provided in the Plan or determined by the Board, the Non-423 Component will operate and be administered
in the same manner as the 423 Component. In addition, the Company may make separate Offerings which vary in terms (provided that
such terms are not inconsistent with the provisions of the Plan or the requirements of an Employee Stock Purchase Plan, except in each
case with respect to a Non-423 Component), and the Company will designate which Designated Company is participating in each separate
Offering and if any Eligible Service Providers will be eligible to participate in a separate Offering. Eligible Employees will be able
to participate in the 423 Component or Non-423 Component of the Plan. Eligible Service Providers will only be able to participate
in the Non-423 Component of the Plan.

 

2.  Administration.

 

(a)  The
Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided
in Section 2(c).

 

(b)  The
Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

 

(i)  To
determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical).

 

(ii)  To
designate from time to time which Related Corporations will be eligible to participate in the Plan as Designated 423 Corporations or as
Designated Non-423 Corporations, which Affiliates will be eligible to participate in the Plan as Designated Non-423 Corporations,
and which Designated Companies will participate in each separate Offering (to the extent that the Company makes separate Offerings).

 

     

     

    

 

(iii)  To
designate from time to time which persons will be eligible to participate in the Non-423 Component of the Plan as Eligible Service
Providers and which Eligible Service Providers will participate in each separate Offering (to the extent that the Company makes separate
Offerings).

 

(iv)  To
construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for its administration.
The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent
it deems necessary or expedient to make the Plan fully effective.

 

(v)  To
settle all controversies regarding the Plan and Purchase Rights granted under the Plan.

 

(vi)  To
suspend or terminate the Plan at any time as provided in Section 12.

 

(vii)  To
amend the Plan at any time as provided in Section 12.

 

(viii)  Generally,
to exercise such powers and to perform such acts as it deems necessary or expedient to promote the best interests of the Company, its
Related Corporations, and Affiliates and to carry out the intent that the 423 Component be treated as an Employee Stock Purchase
Plan.

 

(ix)  To
adopt such rules, procedures and sub-plans relating to the operation and administration of the Plan as are necessary or appropriate under
Applicable Laws to permit or facilitate participation in the Plan by Employees or Eligible Service Providers who are foreign nationals
or employed or providing services or located or otherwise subject to the laws of a jurisdiction outside the United States. Without limiting
the generality of, but consistent with, the foregoing, the Board specifically is authorized to adopt rules, procedures, and sub-plans,
which, for purposes of the Non-423 Component, may be beyond the scope of Section 423 of the Code, regarding, without limitation,
eligibility to participate in the Plan, handling and making of Contributions, establishment of bank or trust accounts to hold Contributions,
payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements,
withholding procedures and handling of share issuances, any of which may vary according to Applicable Laws.

 

(c)  The
Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration is delegated to a Committee,
the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been
delegated to the Committee, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized
to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board and Applicable Laws. The
Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or
all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will
have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan.

 

(d)  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.

 

    2 

     

    

 

3.  Shares
of Common Stock Subject to the Plan.

 

(a)  Number
of Shares Available; Automatic Increases. Subject to the provisions of Section 11(a) relating to Capitalization Adjustments,
the maximum number of shares of Common Stock that may be issued under the Plan will not exceed1,595,445 shares of Common Stock, plus
the number of shares of Common Stock that are automatically added on the first day of each Fiscal Year beginning with the 2022 Fiscal
Year and ending on (and including) the first day of the 2031 Fiscal Year, in each case, in an amount equal to the lesser of (i) half
a percent (0.5%) of the total number of shares of Common Stock outstanding on the last day of the calendar month prior to the date of
such automatic increase, and (ii) 1,595,445 shares of Common Stock. Notwithstanding the foregoing, the Board may act prior to the
first day of any fiscal year to provide that there will be no increase in the share reserve for such fiscal year or that the increase
in the share reserve for such fiscal year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the
preceding sentence.

 

(b)  Share
Recycling. If any Purchase Right granted under the Plan terminates without having been exercised in full, the shares of Common Stock
not purchased under such Purchase Right will again become available for issuance under the Plan.

 

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

 

4.  Grant
of Purchase Rights; Offering.

 

(a)  Offerings.
The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees and/or Eligible Service Providers
under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering
will be in such form and will contain such terms and conditions as the Board will deem appropriate, and, with respect to the 423 Component,
will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights
and privileges. The terms and conditions of an Offering will be incorporated by reference into the Plan and treated as part of the Plan.
The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of
this Plan by reference in the Offering Document or otherwise) the period during which the Offering will be effective, which period will
not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8, inclusive.

 

(b)  More
than One Purchase Right. If a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise
indicates in forms delivered to the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a
Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise
prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase
Right if different Purchase Rights have identical exercise prices) will be exercised.

 

    3 

     

    

 

(c)  Restart
Provision Permitted. To the extent more than one Purchase Period is provided during an Offering, the Board will have the discretion
to structure such Offering so that if the Fair Market Value of a Share on the first Trading Day of a new Purchase Period within that Offering
is less than or equal to the Fair Market Value of a Share on the Offering Date for that Offering, then (i) that Offering will terminate
as of the Purchase Date specified with respect to such Purchase Period, after giving effect to such purchase on the applicable Purchase
Date, (ii) all Contribution amounts not applied to the purchase of Shares after giving effect to such purchase on the applicable Purchase
Date shall be refunded to the applicable Participants and (iii) the Participants in such terminated Offering will be automatically enrolled
in a new Offering beginning on the first Trading Day of such new Offering Period and Purchase Period.

 

5.  Eligibility.

 

(a)  General.
Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to
Employees of a Related Corporation or, solely with respect to the Non-423 Component, Employees of an Affiliate or Eligible Service
Providers.

 

(b)  Grant
of Purchase Rights in Ongoing Offering. The Board may provide that Employees will not be eligible to be granted Purchase Rights under
the Plan if, on the Offering Date, the Employee (i) has not completed at least two (2) years of service since the Employee’s
last hire date (or such lesser period of time as may be determined by the Board in its discretion), (ii) customarily works not more
than twenty (20) hours per week (or such lesser period of time as may be determined by the Board in its discretion), (iii) customarily
works not more than five (5) months per calendar year (or such lesser period of time as may be determined by the Board in its
discretion), (iv) is a highly compensated employee within the meaning of Section 423(b)(4)(D) of the Code, or (v) has not
satisfied such other criteria as the Board may determine consistent with Section 423 of the Code. Unless otherwise determined by
the Board for any Offering Period, an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee
customarily works more than twenty (20) hours per week and more than five (5) months per calendar year.

 

(c)  5%
Stockholders Excluded. No Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase Rights
are granted, such Employee owns stock possessing five (5) percent or more of the total combined voting power or value of all classes
of stock of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of Section 424(d) of the
Code will apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase
Rights and options will be treated as stock owned by such Employee.

 

(d)  $25,000
Limit. As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights only if such Purchase
Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do
not permit such Eligible Employee’s rights to purchase stock of the Company or any Related Corporation to accrue at a rate which,
when aggregated, exceeds U.S. $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with
respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding
at any time.

 

    4 

     

    

 

(e)  Service
Requirement. An Eligible Service Provider will not be eligible to be granted Purchase Rights unless the Eligible Service Provider
is providing bonafide services to the Company or a Designated Company on the applicable Offering Date.

 

(f)  Non-423 Component
Offerings. Notwithstanding anything set forth herein except for Section 5(d) above, the Board may establish additional eligibility
requirements, or fewer eligibility requirements, for Employees and/or Eligible Service Providers with respect to Offerings made under
the Non-423 Component even if such requirements are not consistent with Section 423 of the Code.

 

6.  Purchase
Rights; Purchase Price.

 

(a)  Grant
and Maximum Contribution Rate. On each Offering Date, each Eligible Employee or Eligible Service Provider, pursuant to an Offering
made under the Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock (rounded down to the nearest
whole share) purchasable either with a percentage or with a maximum dollar amount, as designated by the Board; provided however, that
in the case of Eligible Employees, such percentage or maximum dollar amount will in either case not exceed 15% of such Employee’s
earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board
determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering,
unless otherwise provided for in an Offering.

 

(b)  Purchase
Dates. The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will
be exercised and shares of Common Stock will be purchased in accordance with such Offering.

 

(c)  Other
Purchase Limitations. In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of shares
of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number
of shares of Common Stock that may be purchased by all Participants pursuant to such Offering, and (iii) a maximum aggregate number
of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase
of shares of Common Stock issuable on exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number,
then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation
of the shares of Common Stock (rounded down to the nearest whole share) available will be made in as nearly a uniform manner as will be
practicable and equitable.

 

(d)  Purchase
Price. The purchase price of shares of Common Stock acquired pursuant to Purchase Rights will be not less than the lesser of:

 

(i)  an
amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or

 

(ii)  an
amount equal to 85% of the Fair Market Value of the shares of Common Stock on the applicable Purchase Date.

 

    5 

     

    

 

7.  Participation;
Withdrawal; Termination.

 

(a)  Enrollment.
An Eligible Employee may elect to authorize payroll deductions as the means of making Contributions by completing and delivering to the
Company, within the time specified by the Company, an enrollment form provided by the Company or any third party designated by the Company
(each, a “Company Designee”). The enrollment form will specify the amount of Contributions not to exceed the
maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant
under the Plan and will be deposited with the general funds of the Company except where Applicable Laws require that Contributions be
deposited with a Company Designee or otherwise be segregated.

 

(b)  Contributions.
If permitted in the Offering, a Participant may begin Contributions with the first payroll or payment date occurring on or after the Offering
Date (or, in the case of a payroll date or payment date that occurs after the end of the prior Offering but before the Offering Date of
the next new Offering, Contributions from such payroll or payment will be included in the new Offering) or on such other date as set forth
in the Offering. If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions.
If required under Applicable Laws or if specifically provided in the Offering, in addition to or instead of making Contributions by payroll
deductions, a Participant may make Contributions through a payment by cash, check, or wire transfer prior to a Purchase Date, in a manner
directed by the Company or a Company Designee.

 

(c)  Withdrawals.
During an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company or a Company
Designee a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. On such
withdrawal, such Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute as soon
as practicable to such Participant all of his or her accumulated but unused Contributions without interest and such Participant’s
Purchase Right in that Offering will then terminate. A Participant’s withdrawal from that Offering will have no effect on his or
her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment
form to participate in subsequent Offerings.

 

(d)  Termination
of Eligibility. Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either
(i) is no longer an Eligible Employee or Eligible Service Provider for any reason or for no reason, or (ii) is otherwise no
longer eligible to participate. The Company shall have the exclusive discretion to determine when Participant is no longer actively providing
services and the date of the termination of employment or service for purposes of the Plan. As soon as practicable, the Company will distribute
to such individual all of his or her accumulated but unused Contributions without interest.

 

(e)  Leave
of Absence. For purposes of this Section 7, an Employee will not be deemed to have terminated employment or failed to remain
in the continuous employ of the Company or of a Designated Company in the case of sick leave, military leave, or any other leave of absence
approved by the Company; provided that such leave is for a period of not more than three (3) months or reemployment upon the expiration
of such leave is guaranteed by contract or statute. The Company will have sole discretion to determine whether a Participant has terminated
employment and the effective date on which the Participant terminated employment, regardless of any notice period or garden leave required
under local law.

 

(f)  Transfers.
Unless otherwise determined by the Board, a Participant whose employment (or in the case of Eligible Service Providers, service) transfers
or whose employment (or in the case of Eligible Service Providers, service) terminates with an immediate rehire (or in the case of Eligible
Service Providers, reengagement) with no break in employment (or in the case of Eligible Service Providers, service) by or between the
Company and a Designated Company or between Designated Companies will not be treated as having terminated employment (or in the case of
Eligible Service Providers, service) for purposes of participating in the Plan or an Offering; however, if a Participant transfers from
an Offering under the 423 Component to an Offering under the Non-423 Component, the exercise of the Participant’s Purchase Right
will be qualified under the 423 Component only to the extent such exercise complies with Section 423 of the Code. If a Participant
transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the Purchase Right will
remain non-qualified under the Non-423 Component. In the event that a Participant’s Purchase Right is terminated under the Plan,
the Company will distribute as soon as practicable to such individual all of his or her accumulated but unused Contributions.

 

    6 

     

    

 

(g)  No
Transfers of Purchase Rights. During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant.
Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the
Company, by a beneficiary designation as described in Section 10.

 

(h)  No
Interest. Unless otherwise specified in the Offering or required by Applicable Law, the Company will have no obligation to pay interest
on Contributions.

 

8.  Exercise
of Purchase Rights.

 

(a)  On
each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of shares of Common Stock (rounded
down to the nearest whole share), up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering,
at the purchase price specified in the Offering. No fractional shares will be issued unless specifically provided for in the Offering.

 

(b)  Unless
otherwise provided in the Offering, if any amount of accumulated Contributions remains in a Participant’s account after the purchase
of shares of Common Stock on the final Purchase Date in an Offering, then such remaining amount will roll over to the next Offering.

 

(c)  No
Purchase Rights may be exercised to any extent unless the shares of Common Stock to be issued on such exercise under the Plan are covered
by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all Applicable Laws.
If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will
be exercised on such Purchase Date, and the Purchase Date will be delayed until the shares of Common Stock are subject to such an effective
registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than three (3) months
from the original Purchase Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are
not registered and the Plan is not in material compliance with all Applicable Laws, as determined by the Company in its sole discretion,
no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed as soon as practicable to the Participants
without interest.

 

9.  Covenants
of the Company. The Company will seek to obtain from each U.S. federal or state, foreign or other regulatory commission or agency
having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock
thereunder unless the Company determines, in its sole discretion, that doing so would cause the Company to incur costs that are unreasonable.
If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary
for the grant of Purchase Rights or the lawful issuance and sale of Common Stock under the Plan, and at a commercially reasonable cost,
the Company will be relieved from any liability for failure to grant Purchase Rights or to issue and sell Common Stock on exercise of
such Purchase Rights.

 

    7 

     

    

 

10.  Designation
of Beneficiary.

 

(a)  The
Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any shares of Common
Stock or Contributions from the Participant’s account under the Plan if the Participant dies before such shares or Contributions
are delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary.
Any such designation or change must be on a form approved by the Company or as approved by the Company for use by a Company Designee.

 

(b)  If
a Participant dies, in the absence of a valid beneficiary designation, the Company will deliver any shares of Common Stock and Contributions
to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge
of the Company), the Company, in its sole discretion, may deliver such shares of Common Stock and Contributions, without interest, to
the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such
other person as the Company may designate.

 

11.  Capitalization
Adjustments; Dissolution or Liquidation; Corporate Transactions.

 

(a)  Capitalization
Adjustment. 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 the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities
by which the share reserve is to increase automatically each year pursuant to Section 3(a), (iii) the class(es) and number of
securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and
number of securities that are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and
its determination will be final, binding, and conclusive.

 

(b)  Dissolution
or Liquidation. In the event of a dissolution or liquidation of the Company, the Board will shorten any Offering then in progress
by setting a New Purchase Date prior to the consummation of such proposed dissolution or liquidation. The Board will notify each Participant
in writing, prior to the New Purchase Date that the Purchase Date for the Participant’s Purchase Rights has been changed to the
New Purchase Date and that such Purchase Rights will be automatically exercised on the New Purchase Date, unless prior to such date the
Participant has withdrawn from the Offering as provided in Section 7.

 

(c)  Corporate
Transaction. In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving
or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including
a right to acquire the same consideration paid to the stockholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if
any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute
similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common
Stock (rounded down to the nearest whole share) prior to the Corporate Transaction under the outstanding Purchase Rights (with such actual
date to be determined by the Board in its sole discretion), and the Purchase Rights will terminate immediately after such purchase. The
Board will notify each Participant in writing, prior to the New Purchase Date that the Purchase Date for the Participant’s Purchase
Rights has been changed to the New Purchase Date and that such Purchase Rights will be automatically exercised on the New Purchase Date,
unless prior to such date the Participant has withdrawn from the Offering as provided in Section 7.

 

    8 

     

    

 

(d)  Spin-Off.
In the event of a spin-off or similar transaction involving the Company, the Board may take actions deemed necessary or appropriate in
connection with an ongoing Offering and subject to compliance with Applicable Laws (including the assumption of Purchase Rights under
an ongoing Offering by the spun-off company, or shortening an Offering and scheduling a new Purchase Date prior to the closing of such
transaction). In the absence of any such action by the Board, a Participant in an ongoing Offering whose employer ceases to qualify as
a Related Corporation as of the closing of a spin-off or similar transaction will be treated in the same manner as if the Participant
had terminated employment (as provided in Section 7(d)).

 

12.  Amendment,
Termination or Suspension of the Plan.

 

(a)  Plan
Amendment. The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided
in Section 11(a) relating to Capitalization Adjustments, stockholder approval will be required for any amendment of the Plan for
which stockholder approval is required by Applicable Laws, including any amendment that either (i) increases the number of shares
of Common Stock available for issuance under the Plan, (ii) expands the class of individuals eligible to become Participants and
receive Purchase Rights, (iii) materially increases the benefits accruing to Participants under the Plan or reduces the price at
which shares of Common Stock may be purchased under the Plan, (iv) extends the term of the Plan, or (v) expands the types of
awards available for issuance under the Plan, but in each of (i) through (v) above only to the extent stockholder approval is required
by Applicable Laws.

 

(b)  Suspension
or Termination. The Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the
Plan is suspended or after it is terminated.

 

(c)  No
Impairment of Rights. Any benefits, privileges, entitlements, and obligations under any outstanding Purchase Rights granted before
an amendment, suspension, or termination of the Plan will not be materially impaired by any such amendment, suspension, or termination
except (i) with the consent of the person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws,
listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the
regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation
any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by the Board, or (iii) as
necessary to obtain or maintain any special tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase
Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right or the 423 Component
complies with the requirements of Section 423 of the Code.

 

    9 

     

    

 

(d)  Corrections
and Administrative Procedures. Notwithstanding anything in the Plan to the contrary, the Board will be entitled to: (i) permit
Contributions in excess of the amount designated by a Participant in order to adjust for mistakes in the Company’s processing of
properly completed Contribution elections; (ii) establish reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld
from the Participant’s Contributions; (iii) amend any outstanding Purchase Rights or clarify any ambiguities regarding the
terms of any Offering to enable the Purchase Rights to qualify under and/or comply with Section 423 of the Code; and (iv) establish
other limitations or procedures as the Board determines in its sole discretion advisable that are consistent with the Plan. The actions
of the Board pursuant to this paragraph will not be considered to alter or impair any Purchase Rights granted under an Offering as they
are part of the initial terms of each Offering and the Purchase Rights granted under each Offering.

 

13.  Tax
Matters.

 

(a)  Section 409A
of the Code. Purchase Rights granted under the 423 Component are intended to be exempt from the application of Section 409A
of the Code under U.S. Treasury Regulation Section 1.409A-1(b)(5)(ii). Purchase Rights granted under the Non-423 Component to
U.S. taxpayers are intended to be exempt from the application of Section 409A of the Code under the short-term deferral exception
and any ambiguities will be construed and interpreted in accordance with such intent. Subject to Section 13(b) below, Purchase Rights
granted to U.S. taxpayers under the Non-423 Component will be subject to such terms and conditions that will permit such Purchase
Rights to satisfy the requirements of the short-term deferral exception available under Section 409A of the Code, including the requirement
that the shares subject to a Purchase Right be delivered within the short-term deferral period. Subject to Section 13(b) below, in
the case of a Participant who would otherwise be subject to Section 409A of the Code, to the extent the Board determines that a Purchase
Right or the exercise, payment, settlement, or deferral thereof is subject to Section 409A of the Code, the Purchase Right will be
granted, exercised, paid, settled, or deferred in a manner that will comply with Section 409A of the Code, including U.S. Department
of Treasury regulations and other interpretive guidance issued thereunder, including, without limitation, any such regulations or other
guidance that may be issued after the adoption of the Plan. Notwithstanding the foregoing, the Company will have no liability to a Participant
or any other party if the Purchase Right that is intended to be exempt from or compliant with Section 409A of the Code is not so
exempt or compliant or for any action taken by the Board with respect thereto.

 

(b)  No
Guarantee of Tax Treatment. Although the Company may endeavor to (i) qualify a Purchase Right for special tax treatment under
the laws of the United States or jurisdictions outside of the United States, or (ii) avoid adverse tax treatment (e.g., under Section 409A
of the Code), the Company makes no representation to that effect and expressly disavows any covenant to maintain special or to avoid unfavorable
tax treatment, notwithstanding anything to the contrary in this Plan, including Section 13(a) above. The Company will be unconstrained
in its corporate activities without regard to the potential negative tax impact on Participants under the Plan.

 

14.  Tax
Withholding. The Participant will make adequate provision to satisfy the Tax-Related Items withholding obligations, if any, of the
Company and/or the applicable Designated Company which arise with respect to Participant’s participation in the Plan or upon the
disposition of the shares of the Common Stock. The Company and/or the Designated Company may, but will not be obligated to, withhold from
the Participant’s compensation or any other payments due the Participant the amount necessary to meet such withholding obligations,
withholding a sufficient whole number of shares of Common Stock issued following exercise having an aggregate value sufficient to pay
the Tax-Related Items or withhold from the proceeds of the sale of shares of Common Stock, either through a voluntary sale or a mandatory
sale arranged by the Company or any other method of withholding that the Company and/or the Designated Company deems appropriate. The
Company and/or the Designated Company will have the right to take such other action as may be necessary in the opinion of the Company
or a Designated Company to satisfy withholding and/or reporting obligations for such Tax-Related Items. The Company shall not be required
to issue any shares of Common Stock under the Plan until such obligations are satisfied.

 

    10 

     

    

 

15.  Effective
Date of Plan. The Plan will become effective on the Effective Date. No Purchase Rights will be exercised unless and until the Plan
has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the Plan is
adopted (or, if required under Section 12(a) above, amended) by the Board.

 

16.  Miscellaneous
Provisions.

 

(a)  Proceeds
from the sale of shares of Common Stock pursuant to Purchase Rights will constitute general funds of the Company.

 

(b)  A
Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, shares of Common Stock subject
to Purchase Rights unless and until the Participant’s shares of Common Stock acquired on exercise of Purchase Rights are recorded
in the books of the Company (or its transfer agent).

 

(c)  The
Plan and Offering do not constitute an employment or service contract. Nothing in the Plan or in the Offering will in any way alter the
at-will nature of a Participant’s employment, if applicable, or be deemed to create in any way whatsoever any obligation on the
part of any Participant to continue his or her employment or service relationship with the Company, a Related Corporation, or an Affiliate,
or on the part of the Company, a Related Corporation, or an Affiliate to continue the employment or service of a Participant.

 

(d)  The
provisions of the Plan will be governed by the laws of the State of Delaware without resort to that state’s conflicts of laws rules.
For purposes of litigating any dispute that may arise directly or indirectly from the Plan or any Offering, the parties hereby submit
and consent to the exclusive jurisdiction of the State of Delaware and agree that any such litigation shall be conducted only in the courts
of Delaware or the federal courts of the United States located in Delaware and no other courts.

 

(e)  If
any particular provision of the Plan is found to be invalid or otherwise unenforceable, such provision will not affect the other provisions
of the Plan, but the Plan will be construed in all respects as if such invalid provision were omitted.

 

(f) If any provision of the
Plan does not comply with Applicable Laws, such provision will be construed in such a manner as to comply with Applicable Laws.

 

    11 

     

    

 

17.  Definitions.
As used in the Plan, the following definitions will apply to the capitalized terms indicated below:

 

(a)  “423 Component”
means the part of the Plan, which excludes the Non-423 Component, pursuant to which Purchase Rights that satisfy the requirements
