Registration
Rights

 

2.1
Registration.

 

(a)
Registration. The Company must register Investor’s Registrable Securities not later than 90 days after the SEC declares
effectiveness of the IPO filing on the same registration statement and use its commercially reasonable efforts to effect such registration
(including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state
securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities
of any Holder or Holders.

 

    	4

     

    

 

2.2
Company Registration.

 

(a)
Company Registration. If the Company shall determine to register any of its securities either for its own account or the account
of a security holder or holders, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee
benefit plans, a registration relating to the offer and sale of debt securities, a registration relating to a corporate reorganization
or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will:

 

(i)
promptly give written notice of the proposed registration to all Holders; and

 

(ii)
use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance),
except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified
in a written request or requests made by any Holder or Holders received by the Company within fifteen (15) days after such written notice
from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registrable Securities.

 

(b)
Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting,
the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right
of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting
and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing
to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and other holders
of securities of the Company with registration rights to participate therein distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

 

If
a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such
person shall also be excluded therefrom by written notice from the Company or the underwriter. The Registrable Securities or other securities
so excluded shall also be withdrawn from such registration. Any Registrable Securities or other securities excluded or withdrawn from
such underwriting shall be withdrawn from such registration.

 

(c)
Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under
this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such
registration.

 

2.3
Registration on Form S-3.

 

(a)
Request for Form S-3 Registration. After its initial public offering, the Company shall use commercially reasonable efforts to
qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form
S-3 or any comparable or successor form or forms, in addition to the rights contained in the foregoing provisions of this Section 2 and
subject to the conditions set forth in this Section 2.3, if the Company shall receive from a Holder or Holders of Registrable Securities
a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect
to all or part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to be disposed
of and the intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect
to such Registrable Securities as required by Section 2.1(a)(i) and (ii).

 

    	5

     

    

 

(b)
Limitations on Form S-3 Registration. The Company shall not be obligated to effect, or take any action to effect, any such registration
pursuant to this Section 2.3:

 

(i)
In the circumstances described in either Sections 2.1(b)(i), 2.1(b)(iii) or 2.1(b)(v);

 

(ii)
If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose
to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $500,000;
or

 

(iii)
If, in a given twelve-month period, the Company has effected two (2) such registrations in such period.

 

(c)
Deferral. The provisions of Section 2.1(c) shall apply to any registration pursuant to this Section 2.3.

 

(d)
Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute the
Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.1(e) shall apply to such registration.
Notwithstanding anything contained herein to the contrary, registrations effected pursuant to this Section 2.3 shall not be counted as
requests for registration or registrations effected pursuant to Section 2.1.

 

2.4
Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and
2.3 hereof shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses
of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the request
of the Holders of a majority of the Registrable Securities to be registered, or because a sufficient number of Holders shall have withdrawn
so that the minimum offering conditions set forth in Sections 2.1 and 2.3 are no longer satisfied (in which case all participating Holders
shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered), unless
the Holders of a majority of the Registrable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1;
provided, however, in the event that a withdrawal by such Holders is based upon material adverse information relating to
the Company that is different from the information known or available (upon request from the Company or otherwise) to the Holders requesting
registration at the time of their request for registration under Section 2.1, such registration shall not be treated as a counted registration
for purposes of Section 2.1 hereof, even though the Holders do not bear the Registration Expenses for such registration. All Selling
Expenses relating to securities registered on behalf of the Holders shall be borne by the holders of securities included in such registration
pro rata among each other on the basis of the number of Registrable Securities so registered.

 

2.5
Registration Procedures. In the case of each registration effected by the Company pursuant to Section 2, the Company will keep
each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company
will keep such registration effective for a period of ending on the earlier of the date which is one hundred twenty (120) days from the
Maturity Date or until Holder holds no more Registrable Securities, including all securities to be issued upon conversion of the debt
of the Company held by the Holder.

(a)
Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection

of all securities covered by such registration statement for the period set forth in Section 2.5(a) above;

 

(b)
Furnish such number of prospectuses, including any preliminary prospectuses, and other documents incident thereto, including any amendment
of or supplement to the prospectus, as a Holder from time to time may reasonably request;

 

(c)

required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process
in any such states or jurisdictions;

 

(d)
Notify each seller of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing,
and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment
of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include
an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements
therein not misleading or incomplete in light of the circumstances then existing;

 

(e)
Provide a transfer agent and registrar for all Registrable Securities registered pursuant to such registration statement and a CUSIP
number for all such Registrable Securities, in each case not later than the effective date of such registration;

 

(f)
Cooperate with any due diligence investigation undertaken by the Holders, including without limitation by making available documents
and information, as reasonably requested;

 

(g)
Obtain and furnish usual and customary opinions of counsel to the Company and “comfort” letters from the auditors of the
Company;

 

(h)

(i)

perform its obligations under) an underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided
such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder participating
in such underwriting shall also enter into and perform its obligations under such an agreement; provided further, however,
that a Holder will not by any provision in this Agreement be required to enter into any agreement or undertaking in connection with any
registration in this Section 2.5 providing for any indemnification or contribution on the part of the Holder greater than the Holder’s
obligations under Section 2.6 hereof;

 

(j)
promptly make available for inspection by the selling Holders, any underwriter(s) participating in any disposition pursuant to such registration
statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, financial
and other records, pertinent corporate documents, and properties of the Company, each as reasonably requested, and cause the Company’s
officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter,
attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration
statement and to conduct appropriate due diligence in connection therewith; and

 

(k)
notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been
declared effective or a supplement to any prospectus forming a part of such registration statement has been filed.

 

2.6
Indemnification.

 

(a)
To the extent permitted by law, the Company will indemnify and hold harmless each Holder, each of its officers, directors and partners,

to which registration, qualification or compliance has been effected pursuant to this Section 2, and each underwriter, if any, and each
person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages

in the registration statement, any issuer free writing prospectus (as defined in Rule 433 of the Securities Act), any issuer information
(as defined in Rule 433 of the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any

to by the Company, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary

Company in connection with any offering covered by such registration, qualification or compliance, and the Company will reimburse each
such Holder, each of its officers, directors, partners, legal counsel and accountants and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection
with investigating and defending or settling any such claim, loss, damage, liability or action as such expenses are incurred; provided
that the Company will not be liable in any such case to the extent that such untrue statement (or alleged untrue statement), omission
(or alleged omission) or violation (or alleged violation) is made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished to the Company by such Holder, any of such Holder’s
officers, directors, partners, legal counsel or accountants, any person controlling such Holder, such underwriter or any person who controls
any such underwriter, and stated to be specifically for use therein; and provided, further that, the indemnity agreement
contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if
such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed).

 

    	8

     

    

 

(b)
To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to
which such registration, qualification or compliance is being effected, indemnify and hold harmless the Company, each of its directors,
officers, partners, legal counsel and accountants and each underwriter, if any, of the Company’s securities covered by such a registration
statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, each other
such Holder, and each of their officers, directors and partners, and each person controlling each other such Holder, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue
statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or other document (including
any related registration statement, notification, or the like) incident to any such registration, qualification or compliance, or (ii)
any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements

persons, underwriters, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement
(or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and stated to be
specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts
paid in settlement of any such claims, losses, damages or liabilities (or actions in respect thereof) if such settlement is effected
without the consent of such Holder (which consent shall not be unreasonably withheld or delayed); and provided that in no event
shall any indemnity under this Section 2.6(a), when taken together with any contribution under Section 2.6(d), exceed the net proceeds
from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder.

 

(c)
Each party entitled to indemnification under this Section 2.6 (the “Indemnified Party”) shall give notice to the party
required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge

litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim
or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld),
and the Indemnified Party may participate in such defense at such party’s expense; and provided further that the failure
of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section
2.6, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except
with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying
Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting
therefrom.

 

    	9

     

    

 

(d)
If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying
such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss,
liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on
the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability,
claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of
the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and
the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.
No person or entity will be required under this Section 2.6(d) to contribute any amount, when taken together with any indemnity under
Section 2.6(b), in excess of the net proceeds from the offering received by such person or entity, except in the case of fraud or willful
misconduct by such person or entity. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

 

(e)
Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations
of the Company and Holders under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a registration
under this Section 2, and otherwise shall survive the termination of this Agreement.

 

(f)
2.7 Information by Holder. Each Holder of Registrable Securities shall furnish to the Company such information regarding such
Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required
in connection with any registration, qualification, or compliance referred to in this Section 2.

 

2.8

(a)
The holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the provisions
of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion

the benefit of the Company to take and hold such Restricted Securities subject to, and to be bound by, the terms and conditions set forth
in this Agreement, including, without limitation, this Section 2.8 and Section 2.10, except for transfers permitted under Section 2.8(b),

have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, and, if requested
by the Company, such Holder shall have furnished the Company, at its expense, with (i) an opinion of counsel, reasonably satisfactory
to the Company, to the effect that such disposition will not require registration of such Restricted Securities under the Securities
Act or (ii) a “no action” letter from the Commission to the effect that the transfer of such securities without registration
will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of
such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered
by the Holder to the Company.

 

(b)
Permitted transfers include: (i) a transfer not involving a change in beneficial ownership; (ii) transactions involving the distribution
without consideration of Restricted Securities by any Holder to (x) a parent, subsidiary or other affiliate of Holder that is a corporation,
(y) any of its partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate
of any of its partners, members or other equity owners or retired partners, retired members or other equity owners, or (z) a venture
capital fund that is controlled by or under common control with one or more general partners or managing members of, or shares the same
management company with, such Holder (each, an “Affiliated Transfer”); or (iii) transfers in compliance with Rule
144, as long as the Company is furnished with satisfactory evidence of compliance with such Rule; provided, in each case, that
the Holder thereof shall give written notice to the Company of such Holder’s intention to effect such disposition and shall have
furnished the Company with a reasonably detailed description of the manner and circumstances of the proposed disposition. It is agreed
that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances.

Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or

Company under this Section 2 may be transferred orassigned by a Holder only to a transferee or assignee of not less than one hundred
thousand (100,000) shares of Registrable Securities (as presently constituted and subject to subsequent adjustments for stock splits,

is given written notice prior to said transfer or assignment, stating the name and address of the transferee or assignee and identifying
the securities with respect to which such registration rights are intended to be transferred or assigned and (ii) the transferee or assignee
of such rights assumes in writing the obligations of such Holder under this Agreement, including without limitation the obligations set

Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90)-day

Covenants of the Company

 

The
Company hereby covenants and agrees, as follows:

 

3.1
Basic Financial Information and Inspection Rights, Default.

 

(a)
Basic Financial Information. The Company will furnish the following reports to each Holder who owns at least one million (1,000,000)
Shares and/or Conversion Stock (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse
stock splits, and the like) (each, a “Significant Holder”):

 

(i)
As soon as practicable after the end of each fiscal year of the Company, and in any event within one hundred and twenty (120) days after
the end of each fiscal year of the Company, (x) a consolidated balance sheet of the Company and its subsidiaries, if any, as at the end
of such fiscal year, and consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such year,
prepared in accordance with U.S. generally accepted accounting principles consistently applied, certified by independent public accountants
of recognized national standing selected by the Company and (y) a capitalization table in reasonable detail;

 

    	13

     

    

 

(ii)
As soon as practicable after the end of the first, second and third quarterly accounting periods in each fiscal year of the Company,
and in any event within forty-five (45) days after the end of the first, second, and third quarterly accounting periods in each fiscal
year of the Company, (x) an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such
quarterly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such
period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting
from normal year-end audit adjustments and (y) a capitalization table in reasonable detail; and

 

(iii)
As soon as practicable after the end of each month, and in any event within thirty (30) days after the end of each month, an unaudited
consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such monthly period, and unaudited consolidated
statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally
accepted accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments.

 

(b)
Inspection. The Company shall permit each Investor, at such Investor’s expense, to visit and inspect the Company’s
properties, to examine its books of account and records and to discuss the Company’s affairs, finances and accounts with its officers,
all at such reasonable times as may be convenient to the Company and such Investor; provided, however, that the Company shall
not be obligated pursuant to this Section 3.1 to provide access to any information which it reasonably considers to be a trade
secret or similar confidential information.

 

(c)
Qualified Small Business Stock. The Company agrees that for so long as any of the Shares are held by an Investor (or a transferee
in whose hands such Shares are eligible to qualify as “qualified small business stock” within the meaning of Section 1202(c)
of the Internal Revenue Code), it will use commercially reasonable efforts to comply with any applicable filing and reporting requirements
of Section 1202 of the Internal Revenue Code and any regulations promulgated thereunder; provided, however, that “commercially
reasonable efforts” as used in this Section 3.1(c) shall not be construed to require the Company to operate its business in a manner
which would adversely affect its business, limit its future prospects or alter the timing or resource allocation related to its planned
operations or financing activities.

 

(d)
Independent Appraisal. Within three (3) months after the date of this Agreement, the Company shall present to the Board of Directors
and any Investor the results of an independent appraisal, that meets certain requirements of the Internal Revenue Code, of the value
of the Common Stock. The Company will obtain an updated appraisal from time to time as may be reasonably required to facilitate compliance
with Section 409A of the Internal Revenue Code and the safe harbor provisions thereunder.

 

(e)
Default. In the event the Company defaults on any of its obligations under this Agreement, the Company agrees to pay to the Holder
a penalty of a cash payment equal to 0.02857% of the principal amount and interest due and owing under any Note held by the Holder or
that number shares of common stock of the Company equal 1% of the shares of common stock underlying any Note and Warrant held by the
Holder, in total amount per week paid in, whichever is greater.

 

    	14

     

    

 

3.2
Confidentiality. Anything in this Agreement to the contrary notwithstanding, no Holder by reason of this Agreement shall have
access to any trade secrets or similar confidential information of the Company. Each Holder acknowledges that the information received
by them pursuant to this Agreement may be confidential and for its use only, and it will not use any such confidential information in
violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees or
agents having a need to know the contents of such information, and its attorneys or to any prospective purchaser of any Registrable Securities
from such Holder), except in connection with the exercise of rights under this Agreement, unless (i) such Holder has received the prior
written consent of the Company, (ii) the Company has made such information available to the public or (iii) such Holder is required to
disclose such information by a governmental authority.

 

3.3
Termination of Covenants. The covenants set forth in Sections 3.1 to 3.2 shall terminate and be of no further force and effect
after the closing of the earlier of (i) a Qualified IPO or (ii) upon a Change of Control where the Holders receive in exchange for their
shares of Registrable Securities cash or equity securities traded on a nationally recognized exchange. The covenants set forth in Section
3.1 and 3.2 shall also terminate and be of no further force and effect after the Company becomes subject to the provisions of the Exchange
Act.

 

Section
4

 

Right
of First Refusal

 

4.1
Right of First Refusal to Investors. The Company hereby grants to each Investor the right of first refusal to purchase up to 20%
of its pro rata share of New Securities (as defined in this Section 4.1(a)) which the Company may, from time to time, propose to sell
and issue after the date of this Agreement. A Investor’s pro rata share, for purposes of this right of first refusal, is equal
to the ratio of (a) the number of shares of Common Stock owned by such Investor as if the Investor were to convert all of its convertible
debt into shares at the Conversion Price (assuming full conversion of the Shares and exercise of all outstanding convertible securities,
rights, options and warrants, directly or indirectly, into Common Stock held by said Investor) to (b) the total number of shares of Common
Stock outstanding immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding
convertible securities, rights, options and warrants, directly or indirectly). Each Investor shall have a right of over-allotment such
that if any Investor fails to exercise its right hereunder to purchase its pro rata share of New Securities, the other Investors may
purchase the non-purchasing Investor’s portion on a pro rata basis until all such New Securities as to which the Investors had
a right of first refusal have been subscribed for. This right of first refusal shall be subject to the following provisions:

 

(a)
“New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether
now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any
type whatsoever that are, or may become, exercisable or convertible into capital stock.

 

    	15

     

    

 

(b)
In the event the Company proposes to undertake an issuance of New Securities, it shall give each Investor written notice of its intention,
describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each
Investor shall have fifteen (15) days after any such notice is mailed or delivered (the “Election Period”) to agree
to purchase such Holder’s pro rata share of such New Securities and to indicate whether such Holder desires to exercise its over-allotment
option for the price and upon the terms specified in the notice by giving written notice to the Company, in substantially the form attached
hereto as Schedule 1, and stating therein the quantity of New Securities to be purchased.

 

(c)
In the event the Holders fail to exercise fully the right of first refusal and over-allotment rights, if any, within the Election Period,
the Company shall have thirty (30) days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered
thereby shall be closed, if at all, within sixty (60) days from the date of said agreement) to sell that portion of the New Securities
with respect to which the Investors’ right of first refusal option set forth in this Section 4.1 was not exercised, at a price
and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Investors delivered pursuant
to Section 4.1(b). In the event the Company has not sold within such thirty (30) day period following the Election Period, or such sixty
(60) day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first
again offering such securities to the Investors in the manner provided in this Section 4.1.

 

(d)
The right of first refusal granted under this Agreement shall expire upon, and shall not be applicable to the last to occur of: (i) a
Qualified IPO, (ii) upon a Change of Control where the Holders receive in exchange for their shares of Registrable Securities cash or
equity securities traded on a nationally recognized exchange, or (iii) upon the maturity date of the Company debt held by the Holder.

 

Section
5

 

Miscellaneous

 

5.1
Amendment. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended, waived, discharged
or terminated other than by a written instrument referencing this Agreement and signed by the Company and the Holders holding a majority
of the Registrable Securities (excluding any of such shares that have been sold to the public or pursuant to Rule 144); provided,
however, that any person acquiring shares of, or securities exercisable for or convertible into shares of, Registrable Securities
after the date of this Agreement may become a party to this Agreement, by executing a counterpart of this Agreement without any amendment
of this Agreement pursuant to this Section 5.1 or any consent or approval of any other Holder; provided, further, that
if any amendment, waiver, discharge or termination operates in a manner that treats any Investor or group of Investors different from
other Investors or group of Investors, the consent of such Investor or group of Investors, as the case may be, shall also be required
for such amendment, waiver, discharge or termination; and provided further, that neither this Agreement nor any term hereof may
be amended, waived, discharged or terminated without the consent of a Significant Holder, unless such amendment, waiver, discharge or
termination applies to all Significant Holders in the same manner, including any amendment of the defined term “Significant Holder.”
Any such amendment, waiver, discharge or termination effected in accordance with this Section 5.1 shall be binding upon each Holder and
each future holder of all such securities of Holder. Each Holder acknowledges that, subject to the limitations set forth in this Section
5.1, by the operation of this Section 5.1, the holders of a majority of the Registrable Securities (excluding any of such shares that
have been sold to the public or pursuant to Rule 144 and, excluding, with respect to Section 2 (other than Sections 2.8, 2.9 and 2.10),
any of such shares held by Holders whose rights to request registration or inclusion in any registration pursuant to Section 5 have terminated
in accordance with Section 2.14), jointly and not severally, will have the right and power to diminish or eliminate all rights of such
Holder under this Agreement.

 

    	16

     

    

 

5.2
Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered

as may be updated in accordance with the provisions hereof;

 

(b)
if to any Holder, at such address, facsimile number or electronic mail address as shown in the Company’s records, or, until any
such holder so furnishes an address, facsimile number or electronic mail address to the Company, then to and at the address, facsimile
number or electronic mail address of the last holder of such shares for which the Company has contact information in its records; or

 

(c)
if to the Company, one copy should be sent to 1801 Century Park East, Suite 520, Los Angeles, California 90067, Attn: Chief Financial
Officer, or at such other address as the Company shall have furnished in writing to the Investors, with a copy (which shall not constitute
notice) to Thomas E. Puzzo, Law Offices of Thomas E. Puzzo, PLLC, 3823 44th Ave. NE, Seattle, Washington 98105.

 

With
respect to any notice given by the Company under any provision of the Delaware General Corporation Law or the Company’s charter
or bylaws, each party hereto agrees that such notice may be given by facsimile or by electronic mail.

 

Each
such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given when delivered
if delivered personally, or, if sent by mail, at the earlier of its receipt or 72 hours after the same has been deposited in a regularly
maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid or, if sent by facsimile, upon confirmation
of facsimile transfer or, if sent by electronic mail, upon confirmation of delivery when directed to the electronic mail address set
forth on Exhibit A. In the event of any conflict between the Company’s books and records and this Agreement or any notice
delivered hereunder, the Company’s books and records will control absent fraud or error.

 

Subject
to the limitations set forth in Delaware General Corporation Law §232(e), each Investor and Holder consents to the delivery of any
notice to stockholders given by the Company under the Delaware General Corporation Law or the Company’s certificate of incorporation
or bylaws by (i) electronic mail to the electronic mail address set forth on Exhibit A (or to any other electronic mail address
for the Investor or Holder in the Company’s records), (ii) posting on an electronic network together with separate notice to the
Investor or Holder of such specific posting or (iii) any other form of electronic transmission (as defined in the Delaware General Corporation
Law) directed to the Investor or Holder. This consent may be revoked by an Investor or Holder by written notice to the Company and may
be deemed revoked in the circumstances specified in Delaware General Corporation Law §232.

 

    	17

     

    

 

5.3
Governing Law. This Agreement shall be governed in all respects by the internal laws of the State of Delaware as applied to agreements
entered into among Delaware residents to be performed entirely within the State of Delaware, without regard to principles of conflicts
of law.

 

5.4
Successors and Assigns. This Agreement, and any and all rights, duties and obligations hereunder, shall not be assigned, transferred,
delegated or sublicensed by any Investor without the prior written consent of the Company, except (i) to any affiliate or (ii) to an
assignee or transferee who acquires at least 1,000,000 Shares and/or Registrable Securities (as adjusted for any stock combination, stock
split, stock dividend, recapitalization or other similar transaction), it being acknowledged and agreed that any such assignment, including
an assignment contemplated by the preceding clauses (i) or (ii) shall be subject to and conditioned upon any such assignee’s delivery
to the Company and the other Investors of a counterpart signature page hereto pursuant to which such assignee shall confirm their agreement
to be subject to and bound by all of the provisions set forth in this Agreement that were applicable to the assignor of such assignee;
provided, however, that if the Board of Directors of the Company advises the applicable Investor, within ten (10) days after the
Company has received written notice of the proposed transfer, that the Board of Directors has determined in good faith that the assignee
or transferee acquiring such shares pursuant to the preceding clause (ii) is a competitor of the Company, such assignment, transfer,
delegation, or sublicense shall be void. Any attempt by an Investor without such permission to assign, transfer, delegate or sublicense
any rights, duties or obligations that arise under this Agreement shall be prohibited. Subject to the foregoing and except as otherwise
provided herein, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, assigns, heirs,
executors and administrators of the parties hereto.

 

5.5
Entire Agreement. This Agreement and the exhibits hereto constitute the full and entire understanding and agreement between the

the subjects hereof or thereof by any warranties, representations or covenants except as specifically set forth herein.

 

5.6
Delays or Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing
to any party to this Agreement upon any breach or default of any other party under this Agreement shall impair any such right, power
or remedy of such non-defaulting party, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein,
or of or in any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver
of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character
on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions
of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies,
either under this Agreement or by law or otherwise afforded to any party to this Agreement, shall be cumulative and not alternative.

 

5.7
Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable
or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement,
and such court will replace such illegal, void or unenforceable provision of this Agreement with a valid and enforceable provision that
will achieve, to the extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision.
The balance of this Agreement shall be enforceable in accordance with its terms.

a referee sitting without a jury, such referee to be mutually acceptable to the parties or, if no agreement is reached, by a referee
appointed by the Presiding Judge of the California Superior Court for Los Angeles County. This Section 5.16 shall not restrict a party

(i) A change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group
(“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however,
that for purposes of this subsection, (A) the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change
in Control, and (B) if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in 

 
substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, the direct or indirect beneficial ownership of
fifty percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event will not be considered a Change in Control under this subsection (i). For this purpose, indirect beneficial
ownership will include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities which own the Company, as the case may be, either directly or through one or more
subsidiary corporations or other business entities; or

that a majority of members of the Board is replaced during any twelve (12)-month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For
purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or
has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal
to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following
will not constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of
assets by the Company to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or

 Notwithstanding the
foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Section 409A. 

Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to change the
state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such
transaction.

Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in
reducing the number of Shares available for issuance under the Plan. 
 (c) Share Reserve. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan. 
 4.

 (a) The Employee was not previously an
Employee or Director, or the Employee is to become employed by the Company or any of its Parent or Subsidiaries following a bona-fide period of non-employment (within the meaning of Listing Rule 5635(c)(4));
and 
 (b) The grant of the Award or Awards to the Employee is an inducement material to the Employee’s entering into employment with
the Company (or any of its Parent or Subsidiaries, as applicable) in accordance with the Listing Rule. 
 Notwithstanding the foregoing, an
Employee may be granted an Award in connection with an acquisition or merger to the extent permitted by Listing Rule 5635(c)(3). 
 6.
Stock Options. 
 (a) Grant of Options. Subject to the terms and conditions of the Plan, including without limitation the eligibility
requirements of Section 5, an Option may be granted to an Employee at any time and from time to time as will be determined by the Administrator, in its sole discretion. 

(b) Number of Shares. The Administrator will have complete discretion to determine the number of Shares subject to Options granted to
any Participant. 
 (c) Term of Option. The Administrator will determine the term of each Option in its sole discretion. The term of
each Option will be stated in the Award Agreement. 
 (d) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by
the Administrator but will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (ii)
Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

 (iii) Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option,
including the method of payment. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the
Administrator determines in its sole discretion; (5) consideration 

  
 -8- 

 
received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan;
(6) by net exercise; (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment. 

(e) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the
Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (i) a notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any
consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the
name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other
rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment
will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of Relationship as a Service Provider.
If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is
specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the
Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and
the Shares covered by such Option will revert to the Plan. 
 (iii) Disability of Participant. If a Participant ceases to be a
Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in the 

  
 -9- 

 
Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless
otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the
Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with
the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at
the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option
will terminate, and the Shares covered by such Option will revert to the Plan. 
 (v) Tolling Expiration. A Participant’s Award
Agreement may also provide that: 
 (1) if the exercise of the Option following the termination of Participant’s status as a Service
Provider (other than upon the Participant’s death or Disability) would result in liability under Section 16(b), then the Option will terminate on the earlier of (A) the expiration of the term of the Option set forth in the Award
Agreement, or (B) the tenth (10th) day after the last date on which such exercise would result in liability under Section 16(b); or 

(2) if the exercise of the Option following the termination of the Participant’s status as a Service Provider (other than upon the
Participant’s death or Disability) would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act, then the Option will terminate on the earlier of (A) the
expiration of the term of the Option or (B) the expiration of a period of thirty (30) days after the termination of the Participant’s status as a Service Provider during which the exercise of the Option would not be in violation of
such registration requirements. 
 7. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and conditions of the Plan, including without limitation the eligibility
requirements of Section 5, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Employees in such amounts as the Administrator, in its sole discretion, will determine. 

  
 -10- 

 (b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by
an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the

Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may
determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f)
Voting Rights. During the Period of Restriction, Participants holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g) Dividends and Other Distributions. During the Period of Restriction, Participants holding Shares of Restricted Stock will be
entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions
on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 
 (h) Return of Restricted
Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 

8. Restricted Stock Units. 

(a) Grant. Subject to the terms and conditions of the Plan, including without limitation the eligibility requirements of
Section 5, Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant
in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 

(b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to
which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual
goals (including, but not limited to, continued employment or service), applicable federal or state securities laws or any other basis determined by the Administrator in its discretion. 

  
 -11- 

 (c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the
Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting
criteria that must be met to receive a payout. 
 (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be
made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of

(b) Number of Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted to
any Employee.

a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will
have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. 
 (d) Stock
Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and

Appreciation Right granted under the Plan will expire ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement, as determined by the Administrator, in its sole discretion. Notwithstanding the

 (ii) The number of Shares with respect to which the Stock Appreciation Right is exercised. 

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or
in some combination thereof. 
 10. Performance Units and Performance Shares. 

(a) Grant of Performance Units/Shares. Subject to the terms and conditions of the Plan, including without limitation the eligibility
requirements of Section 5, Performance Units and Performance Shares may be granted to Employees at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete
discretion in determining the number of Performance Units and Performance Shares granted to each Participant. 
 (b) Value of Performance
Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of
grant. 
 (c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions
(including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the
Participants. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will
specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit
or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will
be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting
provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share. 

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as
practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of
the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 

  
 -13- 

 (f) Cancellation of Performance Units/Shares. On the date set forth in the Award
Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 

11. Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will
be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its
Parent, or any Subsidiary. 
 12. Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator
makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 
 13.
Adjustments; Dissolution or Liquidation; Merger or Change in Control. 
 (a) Adjustments. In the event that any dividend or
other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to
prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares
covered by each outstanding Award, and the numerical Share limit in Section 3 of the Plan. 
 (b) Dissolution or Liquidation. In
the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised,
an Award will terminate immediately prior to the consummation of such proposed action. 
 (c) Change in Control. In the event of a
merger of the Company with or into another corporation or other entity or a Change in Control, each outstanding Award will be treated as the Administrator determines subject to the restriction in the following paragraph, including, without
limitation, that each Award be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator will not be required to treat all Awards or Participants
similarly in the transaction. 
 In the event that the successor corporation does not assume or substitute for the Award, the Participant
will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and
Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, unless specifically provided otherwise under the applicable Award Agreement, a Company policy applicable to the Participant, or other written agreement
between the Participant and the Company, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and 

  
 -14- 

 
conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a Change in Control, the Administrator will notify the Participant in writing
or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such
period. 
 For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the Award
confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of
Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the
exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal
in fair market value to the per share consideration received by holders of Common Stock in the Change in Control. 
 Notwithstanding
anything in this Section 13(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its
successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not
be deemed to invalidate an otherwise valid Award assumption. 
 14. Tax. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such
earlier time as any tax withholding obligations are due, the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy U.S. federal, state, or local taxes, non-U.S. taxes, or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof). 

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to
time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash or Shares having a fair
market value not in excess of the maximum statutory amount required to be withheld, or (iii) delivering to the Company already-owned Shares having a fair market value not in excess of the maximum statutory amount required to be withheld. The
fair market value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

  
 -15- 

 (c) Compliance With Section 409A. Awards will be designed and
operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest
applicable under Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Section 409A and will be construed and
interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Section 409A the Award will be
granted, paid, settled or deferred in a manner that will meet the requirements of Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A. In no
event will the Company (or any Parent or Subsidiary of the Company, as applicable) reimburse a Participant for any taxes imposed or other costs incurred as a result of Section 409A. 

15. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to
continuing the Participant’s relationship as a Service Provider, nor will they interfere in any way with the Participant’s right or the right of the Company (or any Parent or Subsidiary of the Company) to terminate such relationship at any
time, with or without cause, to the extent permitted by Applicable Laws. 
 16. Date of Grant. The date of grant of an Award will be,
for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable
time after the date of such grant. 
 17. Term of Plan. The Plan will become effective upon its adoption by the Board or its
designated Committee (as applicable). It will continue in effect for a term of ten (10) years from the date adopted by the Board or its designated Committee (as applicable), unless terminated earlier under Section 18 of the Plan.

 18. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent that the Administrator (in
its discretion) determines such approval is necessary and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or
Termination. No amendment, alteration, suspension or termination of the Plan will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing
and signed by the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such
termination. 
 19. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to an Award unless the exercise of such Award and the issuance and delivery of
such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

  
 -16- 

 (b) Investment Representations. As a condition to the exercise of an Award, the
Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required. 
 20. Inability to Obtain Authority. The inability of the
Company to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration or other qualification of the Shares under any U.S. federal or state law, any
non-U.S. law, or the rules and regulations of the Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other governmental or regulatory body, which
authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to
issue or sell such Shares as to which such requisite authority, registration, qualification or rule compliance will not have been obtained. 

21. Clawback. The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and/or benefits with
respect to an Award will be subject to reduction, cancellation, forfeiture, and/or recoupment upon the occurrence of certain specified events, in addition to any applicable vesting, performance or other conditions and restrictions of an Award.
Notwithstanding any provisions to the contrary under this Plan, an Award granted under the Plan shall be subject to the Company’s clawback policy (if any) as may be established and/or amended from time to time. The Board may require a
Participant to forfeit or return to and/or reimburse the Company all or a portion of the Award and/or Shares issued under the Award, any amounts paid under the Award, and any payments or proceeds paid or provided upon disposition of the Shares
issued under the Award, pursuant to the terms of such Company policy or as necessary or appropriate to comply with Applicable Laws.

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 

1. Grant of Option. The Company hereby grants to the individual (“Participant”) named in the Notice of Stock Option Grant of
this Option Agreement (the “Notice of Grant”) an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise
Price”), subject to all of the terms and conditions in this Option Agreement and the Plan, which is incorporated herein by this reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of
the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan will prevail. 
 2. Vesting
Schedule. Except as provided in Section 3, the Option awarded by this Option Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Shares subject to this Option that are 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 Option Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant until the date such
vesting occurs. 
 3. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or
some lesser portion of the balance, of the unvested Option at any time, subject to the terms of the Plan. If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator. 

4. Exercise of Option. 

(a) Right to Exercise. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during
such term only in accordance with the Plan and the terms of this Option Agreement. 
 (b) Method of Exercise. This Option is
exercisable by delivery of an exercise notice (the “Exercise Notice”) in the form attached as Exhibit B to the Notice of Grant or in a manner and pursuant to such procedures as the Administrator may determine, which will state the
election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of
the Plan. The Exercise Notice will be completed by Participant and delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares and of any Tax Obligations (as defined in
Section 6(a)). This Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 

5. Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the
election of Participant: 
 (a) cash in U.S. dollars; 

 (b) check designated in U.S. dollars; 

(c) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 

(d) if Participant is a U.S. employee, surrender of other Shares which have a Fair Market Value on the date of surrender equal to the
aggregate Exercise Price of the Exercised Shares and that are owned free and clear of any liens, claims, encumbrances, or security interests, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any
adverse accounting consequences to the Company. 
 6. Tax Obligations. 

(a) Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or, if different,
Participant’s employer (the “Employer”) or Parent or Subsidiary to which Participant is providing services (together, the Company, Employer and/or Parent or Subsidiary to which the Participant is providing services, the “Service
Recipient”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Option, including, without limitation, (i) all federal, state, and local taxes (including the
Participant’s Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or the Service Recipient or other payment of tax-related items related to
Participant’s participation in the Plan and legally applicable to Participant, (ii) the Participant’s and, to the extent required by the Company (or Service Recipient), the Company’s (or Service Recipient’s) fringe benefit
tax liability, if any, associated with the grant, vesting, or exercise of the Option or sale of Shares, and (iii) any other Company (or Service Recipient) taxes the responsibility for which the Participant has, or has agreed to bear, with
respect to the Option (or exercise thereof or issuance of Shares thereunder) (collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Service
Recipient. Participant further acknowledges that the Company and/or the Service Recipient (A) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Option, including, but not
limited to, the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends or other distributions, and (B) do not commit to and are under no obligation to
structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s liability for Tax Obligations or achieve any particular tax result. Further, if Participant is subject to Tax Obligations in more than one
jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Service Recipient (or former employer, as applicable) may be required to
withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the applicable taxable event, Participant
acknowledges and agrees that the Company may refuse to issue or deliver the Shares. 
 (b) Tax Withholding. When the Option is
exercised, Participant generally will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or
her jurisdiction. Pursuant to such procedures as the Administrator may specify from time to time, the Company and/or Service Recipient 

  
 - 2 - 

 
shall withhold the amount required to be withheld for the payment of Tax Obligations. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to
time, may permit Participant to satisfy such Tax Obligations, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable Shares
having a fair market value equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or such greater amount as Participant may elect if permitted by the Administrator, if such greater amount would
not result in adverse financial accounting consequences), (iii) withholding the amount of such Tax Obligations from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Service Recipient,
(iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax Obligations, or (v) selling a sufficient number of such Shares otherwise deliverable to Participant through such means as the
Company may determine in its sole discretion (whether through a broker or otherwise) equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or such greater amount as Participant may elect if
permitted by the Administrator, if such greater amount would not result in adverse financial accounting consequences). To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy
any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant. Further, if Participant is subject to tax in more than one jurisdiction between the Date of Grant and a date of any relevant taxable or tax withholding event,
as applicable, Participant acknowledges and agrees that the Company and/or the Service Recipient (and/or former employer, as applicable) may be required to withhold or account for tax in more than one jurisdiction. If Participant fails to make
satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the Option exercise, Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such
amounts are not delivered at the time of exercise. 
 (c) Code Section 409A. Under Code Section 409A, a stock
right (such as the Option) that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per share exercise price that is determined by the
Internal Revenue Service (the “IRS”) to be less than the fair market value of an underlying share on the date of grant (a “discount option”) may be considered “deferred compensation.” A stock right that is a
“discount option” may result in (i) income recognition by the recipient of the stock right prior to the exercise of the stock right, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and
interest charges. The “discount option” may also result in additional state income, penalty and interest tax to the recipient of the stock right. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will
agree that the per Share exercise price of this Option equals or exceeds the fair market value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share
exercise price that was less than the fair market value of a Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 

7. 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 certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its
transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation, and delivery, 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. 

  
 - 3 - 

 8. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE
VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER, WHICH UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW IS AT THE WILL OF THE COMPANY (OR THE SERVICE RECIPIENT) AND NOT THROUGH THE ACT OF
BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION 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 COMPANY (OR THE SERVICE RECIPIENT) TO
TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW, MAY BE AT ANY TIME, WITH OR WITHOUT CAUSE. 

9. Nature of Grant. In accepting the Option, Participant acknowledges, understands and agrees that: 

(a) the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of
options, or benefits in lieu of options, even if options have been granted in the past; 
 (b) all decisions with respect to future option
or other grants, if any, will be at the sole discretion of the Company; 
 (c) Participant is voluntarily participating in the Plan; 

(d) the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation; 

(e) the Option and Shares acquired under the Plan and the income and value of same, are not part of normal or expected compensation for
purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or
welfare benefits or similar payments; 
 (f) the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be
predicted with certainty; 
 (g) if the underlying Shares do not increase in value, the Option will have no value; 

(h) if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease in value, even below the
Exercise Price; 

  
 - 4 - 

 (i) for purposes of the Option, Participant’s engagement as a Service Provider will be
considered terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later found to be invalid or in breach of
employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Option Agreement (including by reference in the
Notice of Grant to other arrangements or contracts) or determined by the Administrator, (i) Participant’s right to vest in the Option under the Plan, if any, will terminate as of such date and will not be extended by any notice period
(e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is a Service Provider
or Participant’s employment or service agreement, if any, unless Participant is providing bona fide services during such time); and (ii) the period (if any) during which Participant may exercise the Option after such termination of
Participant’s engagement as a Service Provider will commence on the date Participant ceases to actively provide services and will not be extended by any notice period mandated under employment laws in the jurisdiction where Participant is
employed or terms of Participant’s engagement agreement, if any; the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of his or her Option grant (including
whether Participant may still be considered to be providing services while on a leave of absence and consistent with local law);  

(j) unless otherwise provided in the Plan or by the Copmpany in its discretion, the Option and the benefits evidenced by this Option Agreement
do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and 

(k) the following provisions apply only if Participant is providing services outside the United States: 

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

(ii) Participant acknowledges and agrees that no Service Recipient shall be liable for any foreign exchange rate fluctuation between
Participant’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise; and 

(iii) no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from the termination of
Participant’s engagement as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s
employment or service agreement, if any), and in consideration of the grant of the Option to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against any Service Recipient, waives his or her
ability, if any, to bring any such claim, and releases each Service Recipient from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant
shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

  
 - 5 - 

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

11. 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 in this Option Agreement and any other Option grant materials by and among, as applicable, the Employer or other Service Recipient, the Company and any Parent or Subsidiary
for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Employer may hold certain 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 or directorships held in the Company, details of all Options or
any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. 

Participant understands that Data will be transferred to a stock plan service provider as may be selected by the Company in the future,
which is assisting the Company with the implementation, administration, and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country of
operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request a list with the names and
addresses of any potential recipients of the Data by contacting his or her local People representative. Participant authorizes the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing,
administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing Participant’s participation in the Plan. Participant
understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant understands that if he or she resides outside the United States, he or she may, at any
time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local People
representative. Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her engagement as a
Service Provider and career with the Employer will not be adversely affected; the only adverse consequence of refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant Options or other equity
awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of
Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local People representative.

Plan, the Company shall not be required to issue any certificate or certificates for Shares hereunder prior to the lapse of such reasonable period of time following the date of exercise of the Option as the Administrator may establish from time to
time for reasons of administrative convenience.

document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

decide to deliver any documents related to the Option awarded under the Plan or future options that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant
hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or a third party
designated by the Company. 
 19. Captions. Captions provided herein are for convenience only and are not to serve as a basis for
interpretation or construction of this Option Agreement. 
 20. Agreement Severable. In the event that any provision in this Option
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 Option Agreement. 

21. Amendment, Suspension or Termination of the Plan. By accepting this Option, Participant expressly warrants that he or she has
received an Option 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. 

22. Governing Law and Venue. This Option Agreement will be governed by the laws of California, without giving effect to the conflict of

conditions set forth in an appendix (if any) to this Option Agreement for any country whose laws are applicable to Participant and this Option (as determined by the Administrator in its sole discretion) (the “Country Addendum”). Moreover,
if Participant relocates to one of the countries included in the Country Addendum (if any), the special terms and conditions for such country will apply to Participant, to the extent the Company determines that the application of such terms and
conditions is necessary or advisable for legal or administrative reasons. The Country Addendum (if any) constitutes a part of this Option Agreement. 

24. Modifications to the Agreement. This Option Agreement constitutes the entire understanding of the parties on the subjects covered.
Participant expressly warrants that he or she is not accepting this Option Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Option 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 Option Agreement, the Company reserves the right to revise this Option 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 Section 409A of the Code in connection with
the Option. 

  
 - 8 - 

 25. No Waiver. Either party’s failure to enforce any provision or provisions of
this Option Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Option Agreement. The rights granted both parties herein
are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 

26. Tax Consequences. Participant has reviewed with his or her own tax advisors the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Option Agreement. With respect to such matters, Participant relies solely on such advisors and not on any statements or
representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of this investment or the
transactions contemplated by this Option Agreement.

STOCK OPTION AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the Option granted to Participant under the Plan if
Participant works in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if Participant relocates to
another country after receiving the Option, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan, and/or the Stock Option Agreement to
which this Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of
                    . Such laws are often complex and change frequently. As a result, the Company strongly recommends that Participant not
rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan because the information may be outdated when Participant exercises the Option or sells Shares acquired under the
Plan. 
 In addition, the notifications are general in nature and may not apply to Participant’s particular situation, and the Company is not in a
position to assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as to how the relevant laws in Participant’s country may apply to Participant’s situation. 

Finally, if Participant is a citizen or resident of a country other than the one in which Participant is currently working (or is considered as such for local
law purposes) or if Participant moves to another country after the Option is granted, the information contained herein may not be applicable to Participant.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT 

1. Grant of Restricted Stock Units. The Company hereby grants to the individual (the “Participant”) named in the Notice of
Grant of Restricted Stock Units of this Award Agreement (the “Notice of Grant”) under the Plan an Award of Restricted Stock Units, subject to all of the terms and conditions in this Award Agreement and the Plan, which is incorporated
herein by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Award Agreement, the terms and conditions of the Plan shall 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 or 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock Units, such
Restricted Stock Unit will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. 

3. Vesting Schedule. Except as provided in Section 4, and subject to Section 5, the Restricted Stock Units awarded by this
Award Agreement will vest in accordance with the vesting schedule set forth in the Notice of Grant, subject to Participant continuing to be a Service Provider through each applicable vesting date. 

4. Payment after Vesting. 

(a) General Rule. Subject to Section 8, any Restricted Stock Units that vest will be paid to Participant (or in the event of
Participant’s death, to his or her properly designated beneficiary or estate) in whole Shares. Subject to the provisions of Section 4(b), such vested Restricted Stock Units shall be paid in whole Shares as soon as practicable after
vesting, but in each such case within sixty (60) days following the vesting date. In no event will Participant be permitted, directly or indirectly, to specify the taxable year of payment of any Restricted Stock Units payable under this Award
Agreement. 
 (b) Acceleration. 

(i) Discretionary Acceleration. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser
portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Administrator. If
Participant is a U.S. taxpayer, the payment of Shares vesting pursuant to this Section 4(b) shall in all cases be paid at a time or in a manner that is exempt from, or complies with, Section 409A. The prior sentence may be superseded in a
future agreement or amendment to this Award Agreement only by direct and specific reference to such sentence. 
 (ii) Notwithstanding
anything in the Plan or this Award Agreement or any other agreement (whether entered into before, on or after the Date of Grant), 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 Section 409A, as determined by the Company), other than due to Participant’s death, and if (x) Participant is a U.S.
taxpayer and a “specified employee” within the meaning of 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 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 Participant dies following his or her termination as a Service Provider, in which case, the Restricted Stock
Units will be paid in Shares to Participant’s estate as soon as practicable following his or her death. 
 (c)
Section 409A. It is the intent of this Award Agreement that it and all payments and benefits to U.S. taxpayers hereunder be exempt from, or comply with, the requirements of 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 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 Treasury Regulation Section 1.409A-2(b)(2). However, in no event will the Company reimburse Participant, or be
otherwise responsible for, any taxes or costs that may be imposed on Participant as a result of Section 409A. For purposes of this Award Agreement, “Section 409A” means Section 409A of the Code, and any final Treasury
Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time. 
 5. Forfeiture Upon Termination
as a Service Provider. Notwithstanding any contrary provision of this Award Agreement, if Participant ceases to be a Service Provider for any or no reason, the then-unvested Restricted Stock Units awarded by this Award Agreement will thereupon
be forfeited at no cost to the Company and Participant will have no further rights thereunder. 
 6. Tax Consequences. Participant
has reviewed with his or her own tax advisors the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Award Agreement. With respect to such
matters, Participant relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for
Participant’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Award Agreement. 

7. 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, 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 laws or regulations pertaining to said transfer. 

  
 -2- 

 8. Tax Obligations 

(a) Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or, if different,
Participant’s employer (the “Employer”) or Parent or Subsidiary to which Participant is providing services (together, the Company, Employer and/or Parent or Subsidiary to which the Participant is providing services, the “Service
Recipient”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Restricted Stock Units, including, without limitation, (i) all federal, state, and local taxes (including
the Participant’s Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or the Employer or other payment of tax-related items related to Participant’s
participation in the Plan and legally applicable to Participant, (ii) the Participant’s and, to the extent required by the Company (or Service Recipient), the Company’s (or Service Recipient’s) fringe benefit tax liability, if
any, associated with the grant, vesting, or settlement of the Restricted Stock Units or sale of Shares, and (iii) any other Company (or Service Recipient) taxes the responsibility for which the Participant has, or has agreed to bear, with
respect to the Restricted Stock Units (or settlement thereof or issuance of Shares thereunder) (collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the
Company or the Service Recipient. Participant further acknowledges that the Company and/or the Service Recipient (A) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the
Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends or other distributions, and
(B) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate Participant’s liability for Tax Obligations or achieve any particular tax result.
Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Service
Recipient (or former employer, as applicable) may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required Tax Obligations hereunder
at the time of the applicable taxable event, Participant acknowledges and agrees that the Company may refuse to issue or deliver the Shares. 

(b) Tax Withholding and Default Sell-to-Cover Method of Tax
Withholding. When Shares are issued as payment for vested Restricted Stock Units, Participant generally will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a
non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. Subject to Section 8(c), the minimum amount of Tax Obligations which the Company determines must be withheld
with respect to this Award (“Tax Withholding Obligation”) will be satisfied by Shares being sold on Participant’s behalf at the prevailing market price pursuant to such procedures as the Company may specify from time to time,
including through a broker-assisted arrangement (it being understood that the Shares to be sold must have vested pursuant to the terms of this Award Agreement and the Plan) (the
“Sell-to-Cover Method”). The proceeds from the Sell-to-Cover Method will be
used to satisfy Participant’s Tax Withholding Obligation arising with respect to this Award. In addition to Shares sold to satisfy the Tax Withholding Obligation, additional Shares will be sold to satisfy any associated broker or other fees.
Only whole Shares will be sold through the Sell-to-Cover Method to satisfy any Tax Withholding Obligation and any associated broker or other fees. Any proceeds from the
sale of Shares in excess of the Tax Withholding Obligation and any associated broker or other fees generated 

  
 -3- 

 
through the Sell-to-Cover Method will be paid to Participant in accordance with procedures the Company may specify
from time to time. By accepting this Award, Participant expressly consents to the sale of Shares to cover the Tax Withholding Obligation (and any associated broker or other fees) through the Sell-to-Cover Method and agrees and acknowledges that Participant may not satisfy them by any means other than such sale of Shares, unless required to do so by the Administrator or pursuant to the
Administrator’s express written consent. 
 (c) Administrator Discretion. Notwithstanding the foregoing Sections 8(a) and
8(b), if the Administrator determines it is in the best interests of the Company for Participant to satisfy Participant’s Tax Withholding Obligation by a method other than through the default Sell-to-Cover Method described in Section 8(b), it may permit or require Participant to satisfy Participant’s Tax Withholding Obligation, in whole or in part (without limitation), if permissible by
Applicable Laws, by (i) paying cash, (ii) withholding the amount of such Tax Withholding Obligation from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Service Recipient,
(iii) delivering to the Company Shares that Participant owns and that have vested with a fair market value equal to the amount required to be withheld (or such greater amount up to the maximum statutory rate applicable to the Participant if
permitted by the Administrator and provided such greater amount would not result in adverse financial accounting consequences to the Company as determined by the Administrator), (iv) by having the Company withhold otherwise deliverable Shares having
a fair market value equal to the amount required to be withheld (or such greater amount up to the maximum statutory rate applicable to the Participant if permitted by the Administrator and provided such greater amount would not result in adverse
financial accounting consequences to the Company as determined by the Administrator) or (v) such other means as the Administrator deems appropriate. 

(d) Company’s Obligation to Deliver Shares. For clarification purposes, in no event will the Company issue Participant any Shares
unless and until arrangements satisfactory to the Administrator have been made for the payment of Participant’s Tax Withholding Obligation. If Participant fails to make satisfactory arrangements for the payment of such Tax Withholding
Obligations hereunder at the time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 3 or 4 or Participant’s Tax Withholding Obligations otherwise become due, Participant will permanently forfeit such
Restricted Stock Units to which Participant’s Tax Withholding Obligation relates and any right to receive Shares thereunder and such Restricted Stock Units will be returned to the Company at no cost to the Company. Participant acknowledges and
agrees that the Company may refuse to issue or deliver the Shares if such Tax Obligations are not delivered at the time they are due. 
 9.
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
certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a
brokerage account). After such issuance, recordation, and delivery, 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. 

  
 -4- 

 10. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE
VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER, WHICH UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW IS AT THE WILL OF THE COMPANY (OR THE SERVICE RECIPIENT) AND NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS RESTRICTED STOCK UNIT AWARD 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 SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE
COMPANY (OR THE SERVICE RECIPIENT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW, MAY BE AT ANY TIME, WITH OR WITHOUT CAUSE. 

11. Grant is Not Transferable. Except to the limited extent provided in Section 7, this grant and the rights and privileges
conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will 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. Nature of Grant. In accepting the grant, Participant acknowledges, understands, and agrees that:

 (a) the grant of the 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 in the past;

(c) Participant is voluntarily participating in the Plan; 

(d) the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any pension rights or
compensation; 
 (e) the Restricted Stock Units and the Shares subject to the Restricted Stock Units, and the income and value of same, are
not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses,

 (g) for purposes of the Restricted Stock Units, Participant’s status as a Service
Provider will be considered terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in
breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Award Agreement (including by
reference in the Notice of Grant to other arrangements or contracts) or determined by the Administrator, Participant’s right to vest in the Restricted Stock Units under the Plan, if any, will terminate as of such date and will not be extended
by any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is a
Service Provider or the terms of Participant’s employment or service agreement, if any, unless Participant is providing bona fide services during such time); the Administrator shall have the exclusive discretion to determine when Participant is
no longer actively providing services for purposes of the Restricted Stock Units grant (including whether Participant may still be considered to be providing services while on a leave of absence and consistent with local law); 

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

(ii) 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 purpose; 
 (iii) Participant acknowledges and agrees that none of the Company, the Employer or any Parent or Subsidiary
shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to Participant pursuant to the settlement
of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement; and 
 (iv) no claim or entitlement to
compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from the termination of Participant’s status as a Service Provider (for any reason whatsoever whether or not later found to be invalid or in breach of
employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of the Restricted Stock Units to which Participant is
otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any Parent or Subsidiary or the Service Recipient, waives his or her ability, if any, to bring any such claim, and releases the Company,
any Parent or Subsidiary and the Service Recipient from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to
have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim.

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

14. 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 in this Award Agreement and any other Restricted Stock Unit grant materials by and among, as applicable, the Employer or other Service Recipient, the Company and any Parent
or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Service Recipient may hold certain 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 or directorships held in the Company, details of all
Restricted Stock Units or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan.

 Participant understands that Data will be transferred to a stock plan service provider as may be selected by the Company in
the future, which is assisting the Company with the implementation, administration, and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipients’
country of operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request a list with the
names and addresses of any potential recipients of the Data by contacting his or her local People representative. Participant authorizes the Company, any stock plan service provider selected by the Company and any other possible recipients which may
assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and
managing his or her participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant understands if he or she resides
outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost,
by contacting in writing his or her local People representative. Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke
his or her consent, his or her status as a Service Provider and career with the Service Recipient will not be adversely affected; the only adverse consequence of refusing or withdrawing Participant’s consent is that the Company would not be
able to grant Participant Restricted Stock Units or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in
the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local People representative.

any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Award Agreement. The rights granted both parties herein are cumulative and shall not

Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or non-U.S. law, the tax code
and related regulations or under the rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange
Commission or any other 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, rule compliance, clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Subject to the terms of the Award Agreement and the Plan, the Company shall not be
required to issue any certificate or certificates for Shares hereunder prior to the lapse of such reasonable period of time following the date of vesting of the Restricted Stock Units as the Administrator may establish from time to time for reasons
of administrative convenience.

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. 
 24. 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 Section 409A or to otherwise avoid imposition of any additional tax or income recognition under
Section 409A in connection with this Award of Restricted Stock Units. 
 25. Governing Law; Venue; Severability. This Award
Agreement and the Restricted Stock Units are governed by the internal substantive laws, but not the choice of law rules, of California. For purposes of litigating any dispute that arises under these Restricted Stock Units or this Award Agreement,
the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of San Mateo County, California, or the United States federal courts for the Northern District of
California, and no other courts, where this Award Agreement is made and/or to be performed. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Award Agreement
shall continue in full force and effect.

2022 INDUCEMENT EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the Award of Restricted Stock Units granted to Participant
under the Plan if Participant works in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if
Participant relocates to another country after receiving the Award of Restricted Stock Units, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan, and/or the Restricted Stock Unit
Agreement to which this Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of [DATE]. Such laws are often complex and change frequently. As a result, the
Company strongly recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan because the information may be outdated when Participant vests
in the Restricted Stock Units and acquires Shares, or when Participant subsequently sell Shares acquired under the Plan. 
 In addition, the notifications
are general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as
to how the relevant laws in Participant’s country may apply to Participant’s situation. 
 Finally, if Participant is a citizen or resident of a
country other than the one in which Participant is currently working (or is considered as such for local law purposes) or if Participant moves to another country after receiving the Award of Restricted Stock Units, the information contained herein
may not be applicable to Participant.
