 1. Purposes of the Plan. The purposes of this Plan are: 

 

	 	•	 	 to attract and retain the best available personnel for positions of substantial responsibility,

Section 4 of the Plan. 
 (b) “Applicable Laws” means the legal and regulatory requirements relating to the
administration of equity-based awards, including without limitation the related issuance of shares of Common Stock, including without limitation under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or

Stock, Restricted Stock Units, Performance Units, or Performance Shares.

(f) “Change in Control” means the occurrence of any of the following events: 

(i) Change in Ownership of the Company. 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, 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. Further, 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, 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 
 (ii) Change in Effective Control of the
Company. A change in the effective control of the Company which occurs on the date 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) Change in Ownership of a Substantial Portion of the
Company’s Assets. 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) 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 voting power of which is owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty
percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a
Person described in this subsection (iii)(B)(3). For purposes of this subsection (iii), gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities
associated with such assets. 
 For purposes of this definition, persons will be considered to be acting as a group if they are owners of a

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: (x) its primary purpose is to change the jurisdiction of the Company’s incorporation, or (y) its primary 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.

Stock Subject to the Plan.

Stock Subject to the Plan. Subject to the provisions of Section 14 of the Plan and the automatic increase set forth in Section 3(b), the maximum aggregate
number of Shares that may be issued under the Plan is 10,000,000 Shares, plus (i) any Shares that, as of the day immediately prior to the Registration Date, have been reserved but not issued pursuant to any awards granted under the
Company’s 2010 Stock Plan (the “2010 Plan”), and are not subject to any awards thereunder, plus (ii) any Shares subject to stock options, restricted stock units, or similar awards granted under the 2010 Plan that, on or
after the Registration Date, expire or otherwise terminate without having been exercised or issued in full, are tendered to or withheld by the Company for payment of an exercise price or for tax withholding obligations, or are forfeited to or
repurchased by the Company due to failure to vest, with the maximum number of Shares to be added to the Plan pursuant to the foregoing clauses (i) and (ii) equal to 33,015,235 Shares. In addition, Shares may become available for issuance under
the Plan pursuant to Sections 3(b) and 3(c). The Shares may be authorized, but unissued, or reacquired Common Stock. 
 (b) Automatic
Share Reserve Increase. Subject to the provisions of Sections 14 and 18 of the Plan, the number of Shares available for issuance under the Plan will be increased on the first day of each Fiscal Year beginning with the 2022 Fiscal Year, in
an amount equal to the least of (i) 12,500,000 Shares; (ii) five percent (5%) of the outstanding Shares on the last day of the immediately preceding Fiscal Year; or (iii) such number of Shares determined by the Administrator no later

failure to vest, then the unpurchased Shares (or for Awards other than Options or Stock Appreciation Rights, the forfeited or repurchased Shares), which were subject thereto will become available for future grant or sale under the Plan (unless the
Plan has terminated). With respect to Stock Appreciation Rights, only Shares actually issued (i.e., the net Shares issued) pursuant to a Stock Appreciation Right will cease to be available under the Plan; all remaining Shares under Stock
Appreciation Rights will remain available for future grant or sale under the Plan (unless the Plan has terminated). Shares that actually have been issued under the Plan under any Award will not be returned to the Plan and will not become available
for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares, or Performance Units are repurchased by the Company or are forfeited to the Company
due to failure to vest, such Shares will become available for future grant under the 

  
 -6- 

 
Plan. Shares used to pay the exercise price of an 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, the cash payment will not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject to adjustment as provided in
Section 14, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code and the
Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Sections 3(b) and 3(c). 

(d) Share Reserve. The Company, at all times during the term of this Plan, will reserve and keep available such number of Shares as
will be sufficient to satisfy the requirements of the Plan. 
 4. Administration of the Plan. 

(a) Procedure. 
 (i)
Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 

(ii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under
Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3. 

(iii) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a Committee,
which committee will be constituted to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion, to: 

(i) determine the Fair Market Value; 

(ii) select the Service Providers to whom Awards may be granted hereunder; 

(iii) determine the number of Shares to be covered by each Award granted hereunder; 

(iv) approve forms of Award Agreement for use under the Plan;

regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 

  
 -7- 

 (vi) institute and determine the terms and conditions of an Exchange Program; 

(vii) prescribe, amend, and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable non-U.S. laws or for qualifying for favorable tax treatment under applicable
non-U.S. laws; 
 (viii) construe and interpret the terms of the Plan and Awards granted under the
Plan; 
 (ix) modify or amend each Award (subject to Section 19(c) of the Plan), including without limitation the discretionary
authority to extend the post-termination exercisability period of Awards; provided, however, that in no event will the term of an Option or Stock Appreciation Right be extended beyond its original maximum term; 

(x) allow Participants to satisfy tax withholding obligations in a manner prescribed in Section 15 of the Plan; 

(xi) authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by
the Administrator; 
 (xii) temporarily suspend the exercisability of an Award if the Administrator deems such suspension to be necessary
or appropriate for administrative purposes; 
 (xiii) allow a Participant to defer the receipt of the payment of cash or the delivery of
Shares that otherwise would be due to the Participant under an Award; and 
 (xiv) make all other determinations deemed necessary or
advisable for administering the Plan. 
 (c) Effect of Administrator’s Decision. The Administrator’s
decisions, determinations, and interpretations will be final and binding on all Participants and any other holders of Awards and will be given the maximum deference permitted by Applicable Laws. 

5. Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Shares,
and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 
 6. Stock
Options. 
 (a) Grant of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time
to time, may grant Options to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 
 (b)
Stock Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such
other terms and conditions as the Administrator, in its sole discretion, will determine. 

  
 -8- 

 (c) Limitations. Each Option will be designated in the Award Agreement as either an
Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by
the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this
Section 6(c), Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 

(d) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term
will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted,
owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant
or such shorter term as may be provided in the Award Agreement. 
 (e) 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, subject to the following: 
 (1) In the case of an Incentive Stock Option 

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. 

(B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no
less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (2) In the case of a Nonstatutory
Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(3) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the
Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code. 

(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. 

  
 -9- 

 (iii) Form of Consideration. The Administrator will determine the acceptable form of
consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. 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 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. 

(f) 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: (1) a notice of exercise (in accordance with the procedures that the
Administrator may specify from time to time) from the person entitled to exercise the Option, and (2) full payment for the Shares with respect to which the Option is exercised (together with any applicable tax withholdings). 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 14 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 cessation of the Participant’s Service Provider status 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 cessation of the Participant’s Service Provider status (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 cessation of the Participant’s Service Provider status. Unless otherwise provided
by the Administrator, if on the date of cessation of the Participant’s 

  
 -10- 

 
Service Provider status 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 cessation of the
Participant’s Service Provider status, 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 cessation of the Participant’s Service Provider status (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 twelve (12) months following cessation of the
Participant’s Service Provider status. Unless otherwise provided by the Administrator, if on the date of cessation of the Participant’s Service Provider status 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 cessation of the Participant’s Service Provider status, 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 the 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 the
Participant’s death. Unless otherwise provided by the Administrator, if at the time of death, the 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 cessation of the 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 cessation 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 cessation 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.

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

(c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued pursuant to exercise of 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
conditions as the Administrator, in its sole discretion, will determine. 
 (e) Expiration of Stock Appreciation Rights. A Stock
Appreciation Right granted under the Plan will expire upon the date as determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d) relating to the
term and Section 6(f) relating to exercise also will apply to Stock Appreciation Rights. 
 (f) Payment of Stock Appreciation Right
Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined as the product of: 

(i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; and 

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

At the discretion of the Administrator, the payment upon exercise of a Stock Appreciation Right may be in cash, in Shares of equivalent value,
or in some combination of both. 
 8. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time,
may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify any Period of
Restriction, the number of 

  
 -12- 

 
Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will
hold Shares of Restricted Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this
Section 8 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of any applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as
it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this Section 8, 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 any applicable 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 any applicable Period of Restriction, Service Providers 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 any applicable Period of Restriction, Service Providers 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. 

9. Restricted Stock Units. 

(a) Grant. 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. 

(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. 

  
 -13- 

 (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 settle earned Restricted Stock Units only in cash, Shares, or a combination of both.

 (e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the
Company. 
 10. Performance Units and Performance Shares. 

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers 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 Service Providers.
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. 

  
 -14- 

 (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. Outside Director Award Limitations. No Outside Director may be paid, issued, or granted, in any Fiscal Year, equity awards
(including any Awards issued under this Plan) with an aggregate value (the value of which will be based on the average per Share closing price for the twenty (20) consecutive Trading Days ending on the fifth (5th) Trading Day prior to the grant date of the Award) and any other compensation (including without limitation any cash retainers or fees) that, in the aggregate, exceed $1,000,000. Any Awards or other
compensation paid or provided to an individual for his or her services as an Employee, or for his or her services as a Consultant (other than as an Outside Director), will not count for purposes of the limitation under this Section 11. 

12. 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 of its Subsidiaries. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a
leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and
will be treated for tax purposes as a Nonstatutory Stock Option. 
 13. 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 and 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. 

14. 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, reclassification, 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 (other than any ordinary dividends or other ordinary distributions), 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 of stock that may be delivered under the Plan and/or the number, class, and price of shares of
stock covered by each outstanding Award, and the numerical Share limits in Section 3 of the Plan. 
 (b) Dissolution or
Liquidation. In the event of a 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. 

  
 -15- 

 (c) Merger or 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 provisions of the following paragraph) without a Participant’s consent, including, without
limitation, that (i) Awards will be assumed, or substantially equivalent awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and
prices; (ii) upon written notice to a Participant, that the Participant’s Awards will terminate upon or immediately prior to the consummation of such merger or Change in Control; (iii) outstanding Awards will vest and become
exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part, prior to or upon consummation of such merger or Change in Control, and, to the extent the Administrator determines, terminate upon or
immediately prior to the effectiveness of such merger or Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise
of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith
that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment), or (B) the replacement of such Award with other rights
or property selected by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this Section 14(c), the Administrator will not be obligated to treat all Awards, all
Awards held by a Participant, all Awards of the same type, or all portions of Awards, similarly. 
 In the event that the successor
corporation does not assume or substitute for the Award (or portions thereof), the Participant will fully vest in and have the right to exercise the Participant’s outstanding Option and Stock Appreciation Right (or portions thereof) that is not
assumed or substituted for, including Shares as to which such Award would not otherwise be vested or exercisable, all restrictions on Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units (or portions thereof) not
assumed or substituted for will lapse, and, with respect to such Awards with performance-based vesting (or portions thereof) not assumed or substituted for, all performance goals or other vesting criteria will be deemed achieved at one hundred
percent (100%) of target levels and all other terms and conditions met, in each case, unless specifically provided otherwise under the applicable Award Agreement or other written agreement between the Participant and the Company or any of its
Subsidiaries or Parents, as applicable. In addition, if an Option or Stock Appreciation Right (or portions thereof) is not assumed or substituted for in the event of a merger or Change in Control, the Administrator will notify the Participant in
writing or electronically that such Option or Stock Appreciation Right (or its applicable portion) will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right (or its
applicable portion) will terminate upon the expiration of such period. 
 For the purposes of this subsection (c), an Award will be
considered assumed if, following the merger or Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the consideration (whether stock, cash,
or other securities or property) received in the merger or 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 merger or 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 

  
 -16- 

 
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 merger or Change in Control. 

Notwithstanding anything in this subsection (c) to the contrary, and unless otherwise provided in an Award Agreement or other written
agreement between the Participant and the Company or any of its Subsidiaries or Parents, as applicable, 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. 
 Notwithstanding anything
in this subsection (c) to the contrary, if a payment under an Award Agreement is subject to Section 409A and if the change in control definition contained in the Award Agreement or other written agreement related to the Award does not
comply with the definition of “change in control” for purposes of a distribution under Section 409A, then any payment of an amount that otherwise is accelerated under this Section will be delayed until the earliest time that such
payment would be permissible under Section 409A without triggering any penalties applicable under Section 409A. 
 (d) Outside
Director Awards. With respect to Awards granted to an Outside Director, in the event of a Change in Control, the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares
underlying such Award, including those Shares which would not be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or
other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met, unless specifically provided otherwise under the applicable Award Agreement or other written agreement between
the Participant and the Company or any of its Subsidiaries or Parents, as applicable. 
 15. 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 (or any of its Subsidiaries, Parents, or affiliates employing or retaining the services of a Participant, as applicable) will have the power and the right to deduct or withhold, or
require a Participant to remit to the Company (or any of its Subsidiaries, Parents, or affiliates, as applicable), an amount sufficient to satisfy U.S. federal, state, and local, non-U.S., and 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, check, or other cash equivalents; (ii) electing to have the Company withhold otherwise deliverable cash or Shares having a fair market value equal to the minimum statutory amount required to be withheld or
such greater amount as the Administrator may determine if such amount would not have adverse accounting consequences, as the Administrator determines in 

  
 -17- 

 
its sole discretion; (iii) delivering to the Company already owned Shares having a fair market value equal to the statutory amount required to be withheld or such greater amount as the
Administrator may determine, in each case, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion; (iv) selling a sufficient number of Shares otherwise
deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld; or (v) any combination of the foregoing methods of
payment. The withholding amount will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state, or local marginal income
tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined or such greater amount as the Administrator may determine if such amount would not have adverse accounting
consequences, as the Administrator determines in its sole discretion. 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. 

(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 of its Subsidiaries
or Parents have any obligation or liability under the terms of this Plan to reimburse, indemnify, or hold harmless any Participant or any other person in respect of Awards, for any taxes, interest, or penalties imposed, or other costs incurred, as a
result of Section 409A. 
 16. 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 interfere in any way with the Participant’s right or the right of the Company and its Subsidiaries or Parents, as applicable, to terminate such
relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 17. 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. 
 18. Term of Plan. 

(a) Effectiveness. Subject to Section 22 of the Plan, the Plan will become effective upon the later to occur of
(i) its adoption by the Board or (ii) the business day immediately prior to the Registration Date. 
 (b) Expiration. The
Plan will continue in effect until terminated under Section 19, but (i) no Options that qualify as Incentive Stock Options may be granted after (10) years from the date the Plan is adopted by the Board, and (ii) Section 3(b)
relating to automatic share reserve increases will operate only until the ten (10) year anniversary of the date the Plan is adopted by the Board. 

  
 -18- 

 19. Amendment and Termination of the Plan. 

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

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent 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. 

20. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of 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. 

(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. 
 21. 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. state or federal law or non-U.S. law, or under 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. 
 22. Stockholder Approval. The Plan will be subject to
approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 

23. Forfeiture Events. The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and benefits
with respect to an Award will be subject to reduction, cancellation, forfeiture, recoupment, reimbursement, or reacquisition upon the 

  
 -19- 

 
occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Notwithstanding any provisions to the contrary under this Plan, an
Award will be subject to the Company’s clawback policy as may be established and/or amended from time to time to comply with Applicable Laws (including without limitation pursuant to the listing standards of any national securities exchange or
association on which the Company’s securities are listed, or as may be required by the Dodd-Frank Wall Street Reform and Consumer Protection Act) (the “Clawback Policy”). The Administrator may require a Participant to forfeit,
return, or reimburse the Company all or a portion of the Award and any amounts paid thereunder pursuant to the terms of the Clawback Policy or as necessary or appropriate to comply with Applicable Laws. Unless this Section 23 specifically is
mentioned and waived in an Award Agreement or other document, no recovery of compensation under a Clawback Policy or otherwise will constitute an event that triggers or contributes to any right of a Participant to resign for “good reason”
or “constructive termination” (or similar term) under any agreement with the Company or any Parent or Subsidiary of the Company.

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 

1. Grant of Option. 
 (a)
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 19(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. 

(b) For U.S. taxpayers, the Option will be designated as either an Incentive Stock Option (“ISO”) or a Nonstatutory Stock Option
(“NSO”). If designated in the Notice of Grant as an ISO, this Option is intended to qualify as an ISO under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). However, if this Option is intended to be
an ISO, to the extent that it exceeds the $100,000 rule of Code Section 422(d) it will be treated as an NSO. Further, if for any reason this Option (or portion thereof) will not qualify as an ISO, then, to the extent of such nonqualification,
such Option (or portion thereof) will be regarded as a NSO granted under the Plan. In no event will the Administrator, the Company, or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or
any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 (c) For
non-U.S. taxpayers, the Option will be designated as an NSO. 
 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. Unless specifically provided otherwise in this Option Agreement or other written
agreement between Participant and the Company or any of its Subsidiaries or Parents, as applicable, 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 Vesting Schedule set out in the Notice of Grant and with the applicable provisions of 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, together with any applicable Tax Obligations. 

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 any Parent or Subsidiary to which Participant is providing services (together, the “Service Recipients”), 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 Participant’s Federal Insurance Contributions Act (FICA) obligations) that are required to be
withheld by any Service Recipient or other payment of tax-related items related to Participant’s participation in the Plan and legally applicable to Participant; (ii) Participant’s and, to the
extent required by any Service Recipient, the 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 Service Recipient taxes the
responsibility for which 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 sole responsibility
and may exceed the amount actually withheld by the applicable Service Recipient(s). Participant further acknowledges that no Service 

  
 -2- 

 
Recipient (A) makes any 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) makes any commitment to and is under any 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 applicable Service Recipient(s) (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. Pursuant to such procedures as the Administrator may specify from time
to time, the applicable Service Recipient(s) will 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 in U.S. dollars; (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) having the amount of such Tax Obligations withheld from Participant’s wages or other cash compensation paid to Participant by the applicable Service Recipient(s);
(iv) delivering to the Company Shares that Participant owns and that have vested with 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). 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 applicable Service Recipient(s) (and/or former employer, as applicable) may be required to withhold or account for tax in more than one
jurisdiction. 
 (c) Notice of Disqualifying Disposition of ISO Shares. If the Option is an ISO, and if Participant sells or
otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant immediately
will notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant. 

(d) Section 409A. Under 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 

  
 -3- 

 
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” also may 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 will be solely responsible for Participant’s costs related to such a determination. In no event will the Company or any of its Parent or Subsidiaries have any liability or obligation to reimburse, indemnify, or hold harmless
Participant for any taxes, penalties, and interest that may be imposed, or other costs that may be incurred, as a result of Section 409A. 

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. 
 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 APPLICABLE 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 ANY 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. 

  
 -4- 

 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 Administrator; 
 (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; 
 (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; 
 (i) for purposes of the Option, 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 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 the terms
of 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 will have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of this Option grant (including whether
Participant may still be considered to be providing services while on a leave of absence and consistent with local law);  

  
 -5- 

 (j) unless otherwise provided in the Plan or by the Administrator 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 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 will be liable for any foreign exchange rate fluctuation
between Participant’s local currency and the United States Dollar that may affect the value of the 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 will arise from forfeiture of the Option 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 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
will be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

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 Shares underlying the Option. 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 Service Recipients 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 

  
 -6- 

 
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 may be transferred to a stock plan service provider, as may be selected by the Company in
the future, 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 human resources 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 human resources 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 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 human resources representative. 

12. Address for Notices. Any notice to be given to the Company under the terms of this Option Agreement will be addressed to the
Company at Sumo Logic, Inc., 305 Main Street, Redwood City, CA 94063, or at such other address as the Company may hereafter designate in writing. 

13. Non-Transferability of Option. This Option may not be transferred in any manner otherwise
than by will or by the laws of descent and distribution and may be exercised during the lifetime of Participant only by Participant. 
 14.
Successors and Assigns. The Company may assign any of its rights under this Option Agreement to single or multiple assignees, and this Option Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer herein set forth, this Option Agreement will be binding upon Participant and his or her heirs, executors, administrators, successors, and assigns. The rights and obligations of Participant under this Option Agreement may be
assigned only with the prior written consent of the Company. 

  
 -7- 

 15. Additional Conditions to Issuance of Stock. If at any time the 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 exercise of the Options or the purchase by, or issuance of Shares, to Participant (or his or her estate) hereunder, such exercise, purchase, or 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 Option Agreement and the Plan, the Company will not be required to issue any certificate or certificates for (or make any entry on the books of the Company or of a duly authorized transfer agent of the Company of) the 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. 

16. Language. If Participant has received this Option Agreement or any other 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. 

17. Interpretation. The Administrator will have the power to interpret the Plan and this Option Agreement and to adopt such rules for
the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares subject to the Option have vested).
All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company, and all other interested persons. Neither the Administrator nor any person acting on behalf
of the Administrator will be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Option Agreement. 

18. Electronic Delivery and Acceptance. The Company may, in its sole discretion, 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 require Participant 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. 

  
 -8- 

 20. Option 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 Administrator at any time. 

22. Governing Law and Venue. This Option Agreement and the Option 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 this Option or this Option 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 Option is made and/or to be performed. 

23. Country Addendum. Notwithstanding any provisions in this Option Agreement, this Option will be subject to any special terms and
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 Option 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 Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A in connection with the
Option. 
 25. No Waiver. Either party’s failure to enforce any provision or provisions of this Option Agreement will 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 will 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

  
 -9- 

 
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) will 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.

COUNTRY ADDENDUM 
 Terms and
Conditions 
 This Country Addendum includes additional terms and conditions that govern the stock option (the “Option”) to purchase shares
of the Common Stock of Sumo Logic, Inc. (the “Company”) granted pursuant to the terms and conditions of the Sumo Logic, Inc. 2020 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement to which this Country Addendum is
attached (the “Option Agreement”) to the extent the individual to whom the Option was granted (“Participant”) resides in one of the countries listed below. 

Notifications 
 This Country Addendum also
includes information regarding exchange controls and certain other issues of which Participant should be aware with respect to his or her participation in the Plan. The information is based on the securities, exchange control, and other laws in
effect in the respective countries as of                 , 2020. Such laws often are complex and change frequently. As a result, the Company strongly recommends
that Participant not rely on the information in this Country Addendum as the only source of information relating to the consequences of Participant’s participation in the Plan because the information may be out of date at the time Participant
exercises the Options or sells the Shares acquired under the Plan. 
 In addition, the information contained herein is 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 of
Participant’s country may apply to his or her situation. 
 Finally, if Participant is a citizen or resident of a country other than the one in which
Participant currently is working or transfers to another country after the grant of the Option, or is considered a resident of another country for local law purposes, the information contained herein may not be applicable to Participant in the same
manner. In addition, the Company, in its discretion, will determine the extent to which the terms and conditions contained herein will apply to Participant under these circumstances.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT 

1. Grant of Restricted Stock Units. The Company hereby grants to the individual (“Participant”) named in the Notice of
Restricted Stock Unit Grant of this Award Agreement (the “Notice of Grant”) under the Plan an Award of Restricted Stock Units, and subject to the terms and conditions of this Award Agreement and the Plan, which is incorporated herein by
reference. Subject to Section 19(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 will prevail. 

2. Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive a Share on the date it vests. Unless
and until the Restricted Stock Units will have vested in the manner set forth in Section 3 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 provisions 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 will 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) will 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 the cessation of Participant’s status as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A,
as determined by the Administrator), 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 the cessation of
Participant’s status 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 cessation of Participant’s status 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 or any of its Parent or Subsidiaries have any liability or obligation to reimburse, indemnify, or hold harmless Participant for any taxes,
penalties, and interest that may be imposed, or other costs that may be incurred, as a result of Section 409A. 
 5. Forfeiture
Upon Termination as a Service Provider. Unless specifically provided otherwise in this Award Agreement or other written agreement between Participant and the Company or any of its Subsidiaries or Parents, as applicable, 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) will be solely 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.

 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 any Parent or Subsidiary to which Participant is providing services (together, the “Service Recipients”), 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 Participant’s Federal Insurance Contributions Act (FICA) obligations) that are
required to be withheld by any Service Recipient or other payment of tax-related items related to Participant’s participation in the Plan and legally applicable to Participant;
(ii) Participant’s and, to the extent required by any Service Recipient, the 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 Service Recipient taxes the responsibility for which 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 sole responsibility and may exceed the amount actually withheld by the applicable Service Recipient(s). Participant further acknowledges that no Service Recipient (A) makes any
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) makes any commitment to and is under any 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 applicable Service Recipient(s) (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 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. 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 Administrator 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 proceeds from the sale 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 to satisfy any Tax Withholding Obligation. Any proceeds from the sale of Shares in excess of the Tax Withholding
Obligation and any associated broker or other fees 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 Obligations (and any associated broker or other fees) 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. 

  
 -3- 

 (c) Administrator Discretion. If the Administrator determines that Participant cannot
satisfy Participant’s Tax Withholding Obligation through the default procedure described in Section 8(b) or the Administrator otherwise determines to allow Participant to satisfy Participant’s Tax Withholding Obligation by a method
other than through the default procedure set forth 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 local law,
by (i) paying cash in U.S. dollars; (ii) electing to have the Company withhold otherwise deliverable Shares having a value equal to the minimum amount statutorily required to be withheld (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) having the amount of such Tax Withholding Obligation withheld from Participant’s wages or other cash compensation paid
to Participant by the applicable Service Recipient(s); (iv) delivering to the Company Shares that Participant owns and that have vested with a fair market value equal to the minimum amount statutorily required to be withheld (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); or (v) such other means as the Administrator deems appropriate. 

(d) No Representations. Participant has reviewed with his or her own tax advisers 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 advisers 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) will 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. 
 (e) 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. 
 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 APPLICABLE 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 WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF ANY 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 this Award of Restricted Stock Units, 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; 

(b) all decisions with respect to future Restricted Stock Units or other grants, if any, will be at the sole discretion of the Administrator;

 (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,
long-service awards, pension or retirement, or welfare benefits or similar payments; 
 (f) the future value of the Shares underlying the
Restricted Stock Units is unknown, indeterminable, and cannot be predicted; 

  
 -5- 

 (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 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 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 will 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 Administrator 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: 

(i) 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; 
 (ii) Participant acknowledges and agrees that no Service Recipient will be liable for any foreign exchange rate
fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the 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 
 (iii) no claim or entitlement to compensation or damages will 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 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 will be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal
of such claim.

 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 Shares underlying the Restricted Stock Units. 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 Service Recipients 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 may be transferred to a stock plan service provider, as may be selected by the Company in the future, 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 human resources 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 human resources 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 human resources representative.

Restricted Stock Units awarded under the Plan or future Restricted Stock Units that may be awarded under the Plan by electronic means or require Participant 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. 

17. No Waiver. Either party’s failure to enforce any provision or provisions of this Award Agreement will 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 Award Agreement. The rights granted both parties herein are cumulative and will not constitute a
waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 
 18. Successors and
Assigns. The Company may assign any of its rights under this Award Agreement to single or multiple assignees, and this Award Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on

the prior written consent of the Company. 
 19. Additional Conditions to Issuance of Stock. If at any time the 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 will not be required to issue any
certificate or certificates for (or make any entry on the books of the Company or of a duly authorized transfer agent of the Company of) the 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. 
 20.
Language. If Participant has received this Award Agreement or any other 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. 
 21. Interpretation. The Administrator will have the power to interpret the Plan and this Award Agreement and
to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited 

  
 -8- 

 
to, the determination of whether or not any Restricted Stock Units have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final
and binding upon Participant, the Company, and all other interested persons. Neither the Administrator nor any person acting on behalf of the Administrator will be personally liable for any action, determination, or interpretation made in good faith
with respect to the Plan or this Award Agreement. 
 22. Captions. Captions provided herein are for convenience only and are not to
serve as a basis for interpretation or construction of this Award Agreement. 
 23. Amendment, Suspension or Termination of the Plan.
By accepting this Award, Participant expressly warrants that he or she has received an Award of Restricted Stock Units under the Plan, and has received, read, and understood a description of the Plan. Participant understands that the Plan is
discretionary in nature and may be amended, suspended, or terminated by the Administrator 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 will continue in full force and effect. 

26. Entire Agreement. The Plan is incorporated herein by this reference. The Plan and this Award Agreement (including the appendices
and exhibits referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject
matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. 

27. Country Addendum. Notwithstanding any provisions in this Award Agreement, the Restricted Stock Unit grant will be subject to any
special terms and conditions set forth in an appendix (if any) to this Award Agreement for any country whose laws are applicable to Participant and this Award of Restricted Stock Units (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 Award Agreement.

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 pursuant to the
terms and conditions of the Sumo Logic, Inc. 2020 Equity Incentive Plan (the “Plan”) and the Restricted Stock Unit Agreement to which this Country Addendum is attached (the “Restricted Stock Unit Agreement”) to the extent the
individual to whom the Restricted Stock Units were granted (“Participant”) resides in one of the countries listed below. 
 Notifications

 This Country Addendum also includes information regarding exchange controls and certain other issues of which Participant should be aware with
respect to his or her participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of
                , 2020. Such laws often are complex and change frequently. As a result, the Company strongly recommends that Participant not rely on the
information in this Country Addendum as the only source of information relating to the consequences of Participant’s participation in the Plan because the information may be out of date at the time Participant vest in or receives or sells the
Shares covered by the Restricted Stock Units. 
 In addition, the information contained herein is 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 of Participant’s country may apply
to his or her situation. 
 Finally, if Participant is a citizen or resident of a country other than the one in which Participant currently is working or
transfers to another country after the grant of the Restricted Stock Units, or is considered a resident of another country for local law purposes, the information contained herein may not be applicable to Participant in the same manner. In addition,
the Company, in its discretion, will determine the extent to which the terms and conditions contained herein will apply to Participant under these circumstances.EX-10.3

 Exhibit 10.3 

SUMO LOGIC, INC. 
 2020
EMPLOYEE STOCK PURCHASE PLAN 
 1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated
Companies with an opportunity to purchase Common Stock through accumulated Contributions. The Company intends for the Plan to have two components: a component that is intended to qualify as an “employee stock purchase plan” under
Section 423 of the Code (the “423 Component”) and a component that is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code (the
“Non-423 Component”). The provisions of the 423 Component, accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with
the requirements of Section 423 of the Code. An option to purchase shares of Common Stock under the Non-423 Component will be granted pursuant to rules, procedures, or sub-plans adopted by the Administrator designed to achieve tax,
securities laws, or other objectives for Eligible Employees and the Company. Except as otherwise provided herein, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

 2. Definitions. 

(a) “Administrator” means the Board or any Committee designated by the Board to administer the Plan pursuant to
Section 14. 
 (b) “Affiliate” means any entity, other than a Subsidiary, in which the Company has an equity or other
ownership interest. 
 (c) “Applicable Laws” means the requirements relating to the administration of equity-based awards,
including but not limited to the related issuance of shares of Common Stock, under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and
the applicable laws of any foreign country or jurisdiction where options are, or will be, granted under the Plan. 
 (d)
“Board” means the Board of Directors of the Company. 
 (e) “Change in Control” means the occurrence of
any of the following events: 
 (i) A change in the ownership of the Company that 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, 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. Further, 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, 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 

(ii) A change in the effective control of the Company which occurs on the date 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:

owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least
fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3). For purposes of this subsection (iii), gross fair market value means the value of the assets
of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 

For purposes of this Section 2(e), persons will be considered to be acting as a group if they are owners of a corporation that enters
into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 
 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 primary purpose is to change
the jurisdiction of the Company’s incorporation, or (ii) its primary 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. 
 (f) “Code” means the U.S. Internal Revenue Code of 1986, as amended. Reference to a specific section
of the Code or U.S. Treasury Regulation thereunder will include such section or regulation, any valid regulation or other official applicable guidance promulgated under such section, and any comparable provision of any future legislation or

by the Administrator (if required under applicable local law) for purposes of any separate Offering or for Eligible Employees participating in the Non-423 Component. For purposes of the Plan, the employment
relationship will be treated as continuing intact while the individual is on sick leave or other leave of absence that the Employer approves or is legally protected under Applicable Laws with respect to the Participant’s participation in the
Plan. Where the period of leave exceeds three (3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have terminated three (3) months and
one (1) day following the commencement of such leave. The Administrator, in its discretion, from time to time may, prior to an Enrollment Date for all options to be granted on such Enrollment Date in an Offering, determine (for each Offering
under the 423 Component, on a uniform and nondiscriminatory basis or as otherwise permitted by U.S. Treasury Regulation Section 1.423-2) that the definition of Eligible Employee will or will not include
an individual if he or she: (i) has not completed at least two (2) years of service since his or her last hire date (or such lesser period of time as may be determined by the Administrator in its discretion); (ii) customarily works

may be determined by the Administrator in its discretion); (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code; or (v) is a highly compensated employee within the meaning of Section 414(q) of
the Code with compensation above a certain level or is an officer or subject to the disclosure requirements of 

  
 3 

 
Section 16(a) of the Exchange Act, provided the exclusion is applied with respect to each Offering under the 423 Component in an identical manner to all highly compensated individuals of the
Employer whose employees are participating in that Offering. Each exclusion will be applied with respect to an Offering in a manner complying with U.S. Treasury Regulation Section 1.423-2(e)(2)(ii). Such
exclusions may be applied with respect to an Offering under the Non-423 Component without regard to the limitations of U.S. Treasury Regulation Section 1.423-2.

(p) “Enrollment Date” means the first Trading Day of each Offering Period.

to Section 20(a), the Administrator, in its sole discretion, may determine that any Purchase Period also terminating under such Offering Period will terminate without options being exercised on the Exercise Date that otherwise would have
occurred during such Purchase Period. 
 (s) “Fair Market Value” means, as of any date, and unless otherwise determined by
the Administrator the value of a share of Common Stock determined as follows: 
 (i) For purposes of the Enrollment Date of the first
Offering Period under the Plan, the Fair Market Value will be the initial price to the public as set forth in the final prospectus included within the registration statement in Form S-1 filed with the
Securities and Exchange Commission for the initial public offering of the Company’s Common Stock. 
 (ii) For all other purposes, the
Fair Market Value will be the closing sales price for Common Stock as quoted on any established stock exchange or national market system (including without limitation the New York Stock Exchange, the Nasdaq Global Select Market, the Nasdaq Global
Market or the Nasdaq Capital Market of The Nasdaq Stock Market) on which the Common Stock is listed on the date of determination (or the closing bid, if no sales were reported), as reported in The Wall Street Journal or such other source as
the Administrator deems reliable. If the determination date for the Fair Market Value occurs on a non-Trading Day (i.e., a weekend or holiday), the Fair Market Value will be such price on the immediately
preceding Trading Day, unless otherwise determined by the Administrator. In the absence of an established market for the Common Stock, the Fair Market Value thereof will be determined in good faith by the Administrator. 

The determination of fair market value for purposes of tax withholding may be made in the Administrator’s discretion subject to
Applicable Laws and is not required to be consistent with the determination of Fair Market Value for other purposes. 
 (iii) In the
absence of an established market for the Common Stock, the Fair Market Value thereof will be determined in good faith by the Administrator; or 

(iv) For purposes of the Enrollment Date of the first Offering Period under the Plan, the Fair Market Value will be the initial price to the
public as set forth in the final prospectus included within the Registration Statement.

dates of the applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by U.S. Treasury Regulation
Section 1.423-2(a)(1), the terms of each Offering need not be identical provided that the terms of the Plan and an Offering together satisfy U.S. Treasury Regulation
Section 1.423-2(a)(2) and (a)(3). 
 (w) “Offering Periods” means the
consecutive, overlapping periods of approximately twenty-four (24) months during which an option granted pursuant to the Plan may be exercised, (i) commencing on the first Trading Day on or after June 15 and December 15 of each
year and terminating on the first Trading Day on or after June 15 and December 15, approximately twenty-four (24) months later; provided, however, that the first Offering Period under the Plan will commence with the first Trading Day
on or after the date on which the Securities and Exchange Commission declares the Company’s Registration Statement effective and will end on the first Trading Day on or after December 15, 2022, and provided, further, that the second
Offering Period under the Plan will commence on the first Trading Day on or after June 15, 2021. The duration and timing of Offering Periods may be changed pursuant to Sections 4, 20, and 30.

(bb) “Purchase Price” means an amount equal to eighty-five percent (85%) of the Fair Market Value on the Enrollment Date or
on the Exercise Date, whichever is lower; provided, however, that the Purchase Price may be determined for subsequent Offering Periods by the Administrator subject to compliance with Section 423 of the Code (or any successor rule or provision
or any other Applicable Law, regulation or stock exchange rule) or pursuant to Section 20. 
 (cc) “Registration Date”

 (dd) “Registration Statement” means the registration statement
on Form S-1 filed with the Securities and Exchange Commission for the initial public offering of the Common Stock.

Section of the Code will include such Treasury Regulation or Section, any valid regulation promulgated under such Section, and any comparable provision of any future legislation or regulation amending, supplementing, or superseding such Section or
regulation. 
 3. Eligibility. 

(a) First Offering Period. Any individual who is an Eligible Employee immediately prior to the first Offering Period will be
automatically enrolled in the first Offering Period. 
 (b) Subsequent Offering Periods. Any Eligible Employee on a given Enrollment
Date subsequent to the first Offering Period will be eligible to participate in the Plan, subject to the requirements of Section 5. 

(c) Non-U.S. Employees. Eligible Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether they also are citizens or residents of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from
participation in the Plan or an Offering if the participation of such Eligible Employees is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to
violate Section 423 of the Code. In the case of the Non-423 Component, Eligible Employees may be excluded from participation in the Plan or an Offering if the Administrator determines that participation
of such Eligible Employees is not advisable or practicable. 
 (d) Limitations. Any provisions of the Plan to the contrary
notwithstanding, no Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant
to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or
value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of
the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds twenty-five thousand dollars ($25,000) worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each
calendar year in which such option is outstanding at any time, as determined in accordance with Section 423 of the Code and the regulations thereunder. 

4. Offering Periods. The Plan will be implemented by consecutive Offering Periods with a new Offering Period commencing on the
first Trading Day on or after June 15 and December 15 each year, or on such other dates as the Administrator will determine; provided, however, that the first Offering Period under the Plan will commence with the first Trading Day
on or after the Registration Date and end on the first Trading Day on or after December 15, 2022, and provided, 

  
 6 

 
further, that the second Offering Period under the Plan will commence on the first Trading Day on or after June 15, 2021. The Administrator will have the power to change the duration of
Offering Periods (including the commencement dates thereof) with respect to future Offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter; provided,
however, that no Offering Period may last more than twenty-seven (27) months. 
 5. Participation. 

(a) First Offering Period. An Eligible Employee will be entitled to continue to participate in the first Offering Period pursuant to
Section 3(a) only if such individual submits a subscription agreement authorizing Contributions in a form determined by the Administrator (which may be similar to the form attached hereto as Exhibit A) to the Company’s designated
plan administrator (i) no earlier than the effective date of the Form S-8 registration statement with respect to the issuance of Common Stock under this Plan, and (ii) no later than ten
(10) business days following the effective date of such S-8 registration statement or such date as the Administrator may determine (the “Enrollment Window”). An Eligible Employee’s failure
to submit the subscription agreement during the Enrollment Window will result in the automatic termination of such individual’s participation in the first Offering Period. 

(b) Subsequent Offering Periods. An Eligible Employee may participate in the Plan pursuant to Section 3(b) by (i) submitting
to the Company’s stock administration office (or its designee) a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose, or (ii) following an electronic or other
enrollment procedure determined by the Administrator, in either case on or before a date determined by the Administrator prior to an applicable Enrollment Date. 

6. Contributions. 
 (a)
At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the
Offering Period in an amount not exceeding fifteen percent (15%) of the Compensation that he or she receives on the pay day, provided, however, that the last day upon which Contributions will be made with respect to any Purchase Period will be the
last day of the calendar month immediately prior to the Exercise Date of such Purchase Period (for illustrative purposes, should a pay day occur in the same month as the Exercise Date of a Purchase Period with respect to which a Participant is able
to exercise an option, that Participant may make no Contributions with respect to such pay day). The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by
cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided
in Section 10 hereof. 
 (b) In the event Contributions are made in the form of payroll deductions, such payroll deductions for a
Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the last Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the
Participant as provided in Section 10 hereof; provided, however, that for the first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window. 

  
 7 

 (c) All Contributions made for a Participant will be credited to his or her account under
the Plan and Contributions will be made in whole percentages of his or her Compensation only. A Participant may not make any additional payments into such account. 

(d) A Participant may discontinue his or her participation in the Plan as provided under Section 10. 

(e) Unless otherwise determined by the Administrator: 

(i) During any Purchase Period, a Participant may not increase the rate of his or her Contributions and may only decrease the rate of his or
her Contributions one (1) time and such decrease may be to a Contribution rate of zero percent (0%); and 
 (ii) During any Offering
Period, a Participant may increase or decrease the rate of his or her Contributions to become effective as of the beginning of the next Purchase Period occurring in such Offering Period. 

Any such increase or decrease in a Participant’s rate of Contributions requires the Participant to (i) properly complete and submit
to the Company’s stock administration office (or its designee) a new subscription agreement authorizing the change in Contribution rate in the form provided by the Administrator for such purpose, or (ii) follow an electronic or other
procedure prescribed by the Administrator, in either case, on or before a date determined by the Administrator prior to an applicable Exercise Date or, with respect to increases or decreases in a Participant’s rate of Contributions applicable
to a future Offering Period, on or before the Enrollment Date of such Offering Period. If a Participant has not followed such procedures to change the rate of Contributions, the rate of his or her Contributions will continue at the originally
elected rate throughout the Purchase Period and future Offering Periods and Purchase Periods (unless the Participant’s participation is terminated as provided in Sections 10 or 11). The Administrator may, in its sole discretion, amend the
nature and/or number of Contribution rate changes that may be made by Participants during any Offering Period or Purchase Period and may establish other conditions or limitations as it deems appropriate for Plan administration. Except as otherwise
provided in this subsection (e), any change in the rate of Contributions made pursuant to this Section 6(e) will be effective as of the first (1st) full payroll period following five
(5) business days after the date on which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in payroll deduction rate more quickly). 

(f) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(d), a
Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(d) hereof, Contributions will recommence at the rate originally elected by
the Participant effective: (i) in the event of a limitation described in Section 3(d)(i), as of the beginning of the next Offering Period where Section 3(d)(i) no longer applies, and, (ii) and in the event of a limitation
described in Section 3(d)(ii), as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10. 

(g) Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Participants to participate in the Plan via cash
contributions instead of payroll deductions if (i) payroll deductions are not permitted or advisable under Applicable Law; (ii) the Administrator determines that cash contributions are permissible for Participants participating in the 423
Component; and/or (iii) the Participants are participating in the Non-423 Component. 

  
 8 

 (h) At the time the option is exercised, in whole or in part, or at the time some or all of
the Common Stock issued under the Plan is disposed of (or at any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other
tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security, or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of
the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company
or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to the sale or early disposition of Common Stock by the
Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or use any other method of withholding the Company or the Employer deems appropriate to the extent
permitted by U.S. Treasury Regulation Section 1.423-2(f). 
 7. Grant of Option. On the
Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares
of Common Stock determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that
in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than 5,000 shares of Common Stock (subject to any adjustment pursuant to Section 19) and provided further that such purchase will be subject to the
limitations set forth in Sections 3(d) and 13. The Eligible Employee may accept the grant of such option (i) with respect to the first Offering Period by submitting a properly completed subscription agreement in accordance with the requirements
of Section 5 on or before the last day of the Enrollment Window, and (ii) with respect to any subsequent Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5. The
Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period. Exercise of the option will occur as
provided in Section 8, unless the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period. 

8. Exercise of Option. 

(a) Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares of Common Stock
will be exercised automatically on each Exercise Date, and the maximum number of full shares of Common Stock subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or
her account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the Participant’s account for the
subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant.
During a Participant’s lifetime, a Participant’s option to purchase shares of Common Stock hereunder is exercisable only by him or her. 

(b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to
be exercised may exceed (i) the 

  
 9 

 
number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available
for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise
Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering
Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable
and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The
Company may make a pro rata allocation of the shares of Common Stock available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the
Plan by the Company’s stockholders subsequent to such Enrollment Date. 
 9. Delivery. As soon as reasonably practicable after
each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares of Common Stock purchased upon exercise of his or her option in a form determined by the Administrator
(in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may
utilize electronic or automated methods of share transfer. The Company may require that shares of Common Stock be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of
disqualifying dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares of Common Stock have been
purchased and delivered to the Participant as provided in this Section 9. 
 10. Withdrawal. 

(a) A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose (which may be similar to the
form attached hereto as Exhibit B), or (ii) following an electronic or other withdrawal procedure determined by the Administrator. The Administrator may set forth a deadline of when a withdrawal must occur to be effective prior to a
given Exercise Date in accordance with policies it may approve from time to time. All of the Participant’s Contributions credited to his or her account will be paid to such Participant as soon as administratively practicable after receipt of
notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares of Common Stock will be made for such Offering Period. If a Participant
withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of
Section 5. 
 (b) A Participant’s withdrawal from an Offering Period will not have any effect on his or her eligibility to
participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws. 

  
 10 

 11. Termination of Employment. Upon a Participant’s ceasing to be an Eligible
Employee, for any reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the
Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such Participant’s option will be automatically terminated. Unless determined otherwise by the
Administrator in a manner that, with respect to an Offering under the 423 Component, is permitted by, and compliant with, Code Section 423, a Participant whose employment transfers between entities through a termination with an immediate rehire
(with no break in service) by the Company or a Designated Company will not be treated as terminated under the Plan; however, if a Participant transfers from an Offering under the 423 Component to the Non-423 Component, the exercise of the option
will be qualified under the 423 Component only to the extent it complies with Section 423 of the Code; further, no Participant will be deemed to switch from an Offering under the Non-423 Component to an Offering under the 423 Component or vice
versa unless (and then only to the extent) such switch would not cause the 423 Component or any option thereunder to fail to comply with Code Section 423. 

12. Interest. No interest will accrue on the Contributions of a participant in the Plan, except as may be required by Applicable Law,
as determined by the Company, and if so required by the laws of a particular jurisdiction, will apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation
Section 1.423-2(f). 
 13. Stock. 

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of
Common Stock that will be made available for sale under the Plan will be 2,000,000 shares of Common Stock, plus the number of shares of Common Stock to be added to the Plan pursuant to the next sentence. The number of shares of Common Stock
available for issuance under the Plan will be increased on the first day of each Fiscal Year beginning with the 2022 Fiscal Year equal to the least of (i) 2,500,000 shares of Common Stock; (ii) one percent (1%) of the outstanding
shares of Common Stock on the last day of the immediately preceding Fiscal Year; or (iii) an amount determined by the Administrator. 

(b) Until the shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), a Participant will have only the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares. 

(c) Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the Participant or, if so
required under Applicable Laws, in the name of the Participant and his or her spouse. 
 14. Administration. The Plan will be
administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of
the Plan, to delegate ministerial duties to any of the Company’s employees, to designate separate Offerings under the Plan, to designate Subsidiaries and Affiliates as participating in the 423 Component or Non-423 Component, to determine
eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary or advisable for the 

  
 11 

 
administration of the Plan (including, without limitation, to adopt such procedures, sub-plans, and appendices to the enrollment agreement as are necessary
or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans and appendices may take precedence over other provisions
of this Plan, with the exception of Section 13(a) hereof, but unless otherwise superseded by the terms of such sub-plan or appendix, the provisions of this Plan will govern the operation of such sub-plan or appendix). Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate
Offering under the 423 Component, or if the terms would not qualify under the 423 Component, in the Non-423 Component, in either case unless such designation would cause the 423 Component to violate the
requirements of Section 423 of the Code. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling
of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency,
obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that, to
the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a
non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision, and determination made by
the Administrator will, to the full extent permitted by law, be final and binding upon all parties. 
 15. Designation of
Beneficiary. 
 (a) If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any
shares of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of
such shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death
prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective. 

(b) Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Administrator. In the
event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such shares and/or cash to the executor or administrator
of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or
relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

(c) All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding
Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f). 
 16. Transferability. Neither Contributions credited to a
Participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan 

  
 12 

 
may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the Participant.
Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof. 

17. Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the
Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by
Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party, provided that, if such segregation or deposit with an independent third party is required by Applicable Laws, it will apply
to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f). Until shares of Common Stock are issued,
Participants will have only the rights of an unsecured creditor with respect to such shares. 
 18. Reports. Individual accounts will
be maintained for each Participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of
Common Stock purchased and the remaining cash balance, if any. 
 19. Adjustments, Dissolution, Liquidation, Merger, or Change in
Control. 
 (a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock,
other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination,
reclassification, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs (other than any ordinary dividends or other ordinary
distributions), the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common
Stock that may be delivered under the Plan, the Purchase Price per share, the class and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in
progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the
date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to
the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 

(c) Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an
equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which
such option relates will be shortened by setting a New Exercise Date on which such Offering Period 

  
 13 

 
will end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically
prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such
date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 
 20. Amendment or
Termination. 
 (a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at
any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next
Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to
Section 19). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest
thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12 hereof) as soon as administratively practicable. 

(b) Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change the Offering Periods or
Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit
Contributions in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution elections, establish reasonable waiting and adjustment periods and/or
accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator
determines in its sole discretion advisable that are consistent with the Plan. 
 (c) In the event the Administrator determines that the
ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting
consequence including, but not limited to: 
 (i) amending the Plan to conform with the safe harbor definition under the Financial
Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time; 

(ii) altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the
time of the change in Purchase Price; 
 (iii) shortening any Offering Period or Purchase Period by setting a New Exercise Date, including
an Offering Period or Purchase Period underway at the time of the Administrator action; 

  
 14 

 (iv) reducing the maximum percentage of Compensation a Participant may elect to set aside
as Contributions; and 
 (v) reducing the maximum number of shares of Common Stock a Participant may purchase during any Offering Period or
Purchase Period. 
 Such modifications or amendments will not require stockholder approval or the consent of any Participants. 

21. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be
deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

22. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of such
option and the issuance and delivery of such shares of Common Stock pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Exchange
Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares of Common Stock may then be listed, and will be further subject to the approval of counsel for the Company with respect to such
compliance. 
 As a condition to the exercise of an option, the Company may require the person exercising such option 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 by
any of the aforementioned applicable provisions of law. 
 23. Section 409A. The Plan is intended to be exempt from the application
of Section 409A, and, to the extent not exempt, is intended to comply with Section 409A and any ambiguities herein will be interpreted to so be exempt from, or comply with, Section 409A. In furtherance of the foregoing and
notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Section 409A or that any provision in the Plan would cause an option under the Plan to be subject
to Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the
Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Section 409A, but only to the extent any such amendments or action by the
Administrator would not violate Section 409A. Notwithstanding the foregoing, the Company and any of its Parent or Subsidiaries will have no obligation to reimburse, indemnify, or hold harmless a Participant or any other party if the option to
purchase Common Stock under the Plan that is intended to be exempt from or compliant with Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the
option to purchase Common Stock under the Plan is compliant with Section 409A. 
 24. Term of Plan. The Plan will become
effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It will continue in effect for a term of twenty (20) years, unless sooner terminated under Section 20. 

  
 15 

 25. Stockholder Approval. The Plan will be subject to approval by the stockholders of
the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 

26. Governing Law. The Plan will be governed by, and construed in accordance with, the laws of the State of California (except its choice-of-law provisions). 
 27. No Right to Employment.
Participation in the Plan by a Participant will not be construed as giving a Participant the right to be retained as an employee of the Company or a Subsidiary or Affiliate, as applicable. Furthermore, the Company or a Subsidiary or Affiliate may
dismiss a Participant from employment at any time, free from any liability or any claim under the Plan. 
 28. Severability. If any
provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability will not affect the remaining parts of the Plan,
and the Plan will be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included. 

29. Compliance with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed
accordingly. 
 30. Automatic Transfer to Low Price Offering Period. To the extent permitted by Applicable Laws, if the Fair Market
Value on any Exercise Date in an Offering Period is lower than the Fair Market Value on the Enrollment Date of such Offering Period, then all Participants in such Offering Period automatically will be withdrawn from such Offering Period immediately
after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period as of the first day thereof.

	  	Change in Payroll Deduction Rate	  		  	

 1.
                                         
                hereby elects to participate in the Sumo Logic, Inc. 2020 Employee Stock Purchase Plan (the “Plan”) and subscribes to purchase shares of
the Company’s Common Stock in accordance with this Subscription Agreement and the Plan. Any capitalized terms not specifically defined in this Subscription Agreement will have the meaning ascribed to them under the Plan. 

2. I hereby authorize and consent to payroll deductions from each paycheck in the amount of
        % of my Compensation (from 1% to 15%); a decrease in rate may be to zero percent (0%)) during the Offering Period in accordance with the Plan. (Please note that no fractional percentages are
permitted.) 
 3. I understand that, subject to the terms and conditions of the Plan: 

(a) The last day upon which such deduction will be made with respect to any Purchase Period will be the last day of the calendar month
immediately prior to the Exercise Date of such Purchase Period (for illustrative purposes, should a pay day occur in the same month as the Exercise Date of a Purchase Period with respect to which I am able to exercise an option, no deduction will be
made with respect to such pay day); 
 (b) During any Purchase Period, I am permitted to decrease the rate of my Contributions only one
(1) time, and such decrease may be to zero percent (0%); and 
 (c) During any Offering Period, I am permitted to increase or decrease
the rate of my Contributions to become effective beginning on the next occurring Purchase Period of that Offering Period. 
 4. I understand
that said payroll deductions will be accumulated for the purchase of shares of Common Stock at the applicable Purchase Price determined in accordance with the Plan. I understand that if I do not withdraw from an Offering Period, any accumulated
payroll deductions will be used to automatically exercise my option and purchase Common Stock under the Plan. I further understand that if I am outside of the U.S., my payroll deductions will be converted to U.S. dollars at an exchange rate selected
by the Company on the purchase date. 
 5. I have received a copy of the complete Plan and its accompanying prospectus. I understand that my
participation in the Plan is in all respects subject to the terms of the Plan. 

 6. Shares of Common Stock purchased for me under the Plan should be issued in the name(s) of
                             (Eligible Employee or Eligible Employee and spouse only). 

7. If I am a U.S. taxpayer, I understand that if I dispose of any shares received by me pursuant to the Plan within two (2) years after
the Offering Date (the first day of the Offering Period during which I purchased such shares) or one (1) year after the Exercise Date, I will be treated for federal income tax purposes as having received ordinary income at the time of such
disposition in an amount equal to the excess of the fair market value of the shares at the time such shares were purchased by me over the price that I paid for the shares. I hereby agree to notify the Company in writing within thirty
(30) days after the date of any disposition of my shares and I will make adequate provision for federal, state or other tax withholding obligations, if any, which arise upon the disposition of the Common Stock. The Company
may, but will not be obligated to, withhold from my compensation the amount necessary to meet any applicable withholding obligation including any withholding necessary to make available to the Company any tax deductions or benefits attributable to
sale or early disposition of Common Stock by me. If I dispose of such shares at any time after the expiration of the two (2)-year and one (1)-year holding periods, I understand that I will be treated for federal income tax purposes as having
received income only at the time of such disposition, and that such income will be taxed as ordinary income only to the extent of an amount equal to the lesser of (a) the excess of the fair market value of the shares at the time of such
disposition over the purchase price which I paid for the shares, or (b) 15% of the fair market value of the shares on the first day of the Offering Period. The remainder of the gain, if any, recognized on such disposition will be taxed as capital
gain. 
 8. For employees that may be subject to tax in non U.S. jurisdictions, I acknowledge and agree that, regardless of any action taken
by the Company or any Designated Company with respect to any or all income tax, social security, social insurances, National Insurance Contributions, payroll tax, fringe benefit, or other tax-related items
related to my participation in the Plan and legally applicable to me including, without limitation, in connection with the grant of such options, the purchase or sale of shares of Common Stock acquired under the Plan and/or the receipt of any
dividends on such shares (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains my responsibility and may exceed the
amount actually withheld by the Company or a Designated Company. Furthermore, I acknowledge that the Company and/or any Designated Company (a) make no representations or undertakings regarding the treatment of any
Tax-Related Items in connection with any aspect of the options under the Plan and (b) do not commit to and are under no obligation to structure the terms of the grant of options or any aspect of my
participation in the Plan to reduce or eliminate my liability for Tax-Related Items or achieve any particular tax result. Further, if I have become subject to tax in more than one jurisdiction between the date
of my enrollment and the date of any relevant taxable or tax withholding event, as applicable, I acknowledge that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 
 Prior to the purchase of shares of Common Stock under
the Plan or any other relevant taxable or tax withholding event, as applicable, I agree to make adequate arrangements satisfactory to the Company and/or the applicable Designated Company to satisfy all
Tax-Related Items. In this regard, I authorize the Company and/or the applicable Designated Company, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with
regard to all Tax-Related Items by one or a combination of the following: (a) withholding from my wages or Compensation paid to me by the Company and/or the applicable Designated Company; or
(b) withholding from proceeds of the sale of the shares of Common Stock purchased under the Plan either through a voluntary sale or through a mandatory sale arranged by the Company (on my 

  
 2 

 
behalf pursuant to this authorization). Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering
applicable maximum withholding rates, in which case I will receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent. 

Finally, I agree to pay to the Company or the applicable Designated Company any amount of Tax-Related
Items that the Company or the applicable Designated Company may be required to withhold as a result of my participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to purchase shares of Common Stock
under the Plan on my behalf and/or refuse to issue or deliver the shares or the proceeds of the sale of shares if I fail to comply with my obligations in connection with the Tax-Related Items. 

9. By electing to participate in the Plan, I acknowledge, understand and agree that: 

(a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated
by the Company at any time, to the extent provided for in the Plan; 
 (b) all decisions with respect to future grants under the Plan, if
applicable, will be at the sole discretion of the Company; 
 (c) the grant of options under the Plan will not create a right to employment
or be interpreted as forming or amending an employment or service contract with the Company, or any Designated Company, and will not interfere with the ability of the Company or any Designated Company, as applicable, to terminate my employment (if
any); 
 (d) I am voluntarily participating in the Plan; 

(e) the options granted under the Plan and the shares of Common Stock underlying such options, and the income and value of same, are not
intended to replace any pension rights or compensation; 
 (f) the options granted under the Plan and the shares of Common Stock underlying
such options, and the income and value of same, are not part of my normal or expected compensation for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or similar payments; 

(g) the future value of the shares of Common Stock offered under the Plan is unknown, indeterminable and cannot be predicted with certainty;

 (h) the shares of Common Stock that I acquire under the Plan may increase or decrease in value, even below the Purchase Price; 

(i) no claim or entitlement to compensation or damages will arise from the forfeiture of options granted to me under the Plan as a result of
the termination of my status as an Eligible Employee (for any reason whatsoever, and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any)
and, in consideration of the grant of options under the Plan to which I am otherwise not entitled, I irrevocably agree never to institute a claim against the Company, or any Designated Company, waive my ability, if any, to bring such claim, and
release the Company, and 

  
 3 

 
any Designated Company from any such claim that may arise; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, I will be deemed irrevocably to have
agreed to not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claim; and 

(j) in the event of the termination of my status as an Eligible Employee (for any reason whatsoever, whether or not later found to be invalid
or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any), my right to participate in the Plan and any options granted to me under the Plan, if any, will terminate effective as of the
date that I am no longer actively employed by the Company or one of its Designated Companies and, in any event, will not be extended by any notice period mandated under the employment laws in the jurisdiction in which I am employed or the terms of
my employment agreement, if any (e.g., active employment would not include a period of “garden leave” or similar period pursuant to the employment laws in the jurisdiction in which I am employed or the terms of my employment
agreement, if any); the Company will have the exclusive discretion to determine when I am no longer actively employed for purposes of my participation in the Plan (including whether I may still be considered to be actively employed while on a leave
of absence). 
 10. I understand that the Company and/or any Designated Company may collect, where permissible under applicable law
certain personal information about me, including, but not limited to, my name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of Common Stock or
directorships held in the Company, details of all options granted under the Plan or any other entitlement to shares of Common Stock awarded, canceled, exercised, vested, unvested or outstanding in my favor (“Data”), for the
exclusive purpose of implementing, administering and managing the Plan. I understand that Company may transfer my Data to the United States, which is not considered by the European Commission to have data protection laws equivalent to the laws in my
country. I understand that the Company will transfer my Data to its designated broker, or such other 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. I understand that the recipients of the Data may be located in the United States or elsewhere, and that a recipient’s country of operation (e.g., the United States) may have different, including less stringent, data
privacy laws that the European Commission or my jurisdiction does not consider to be equivalent to the protections in my country. I understand that I may request a list with the names and addresses of any potential recipients of the Data by
contacting my local human resources representative. I authorize the Company, the Company’s designated broker and any other possible recipients which may assist the Company 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 my participation in the Plan. I understand that Data will be held only as long as is necessary to implement,
administer and manage my participation in the Plan. I understand that I 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 my local human resources representative. Further, I understand that I am providing the consents herein on a purely voluntary basis. If I do not consent, or if I later seek to revoke my
consent, my employment status or career with the Company or any Designated Company will not be adversely affected; the only adverse consequence of refusing or withdrawing my consent is that the Company would not be able to grant me options under the
Plan or other equity awards, or administer or maintain such awards. Therefore, I understand that refusing or withdrawing my consent may affect my ability to participate in the Plan. For more information on the consequences of my refusal to consent
or withdrawal of consent, I understand that I may contact my local human resources representative. 

  
 4 

 If I am an employee outside the U.S., I understand that in accordance with applicable
law, I have the right to access, and to request a copy of, the Data held about me. I also understand that I have the right to discontinue the collection, processing, or use of my Data, or supplement, correct, or request deletion of my Data. To
exercise my rights, I may contact my local human resources representative. 
 I hereby explicitly and unambiguously consent to the
collection, use and transfer, in electronic or other form, of my personal data as described herein and any other Plan materials by and among, as applicable, the Company and its Subsidiaries for the exclusive purpose of implementing, administering
and managing my participation in the Plan. I understand that my consent will be sought and obtained for any processing or transfer of my data for any purpose other than as described in the enrollment form and any other plan materials. 

11. If I have received the Subscription Agreement or any other 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, subject to applicable laws. 

12. The provisions of the Subscription Agreement and these appendices are severable and if any one or more provisions are determined to be
illegal or otherwise unenforceable, in whole or in part, the remaining provisions will nevertheless be binding and enforceable. 
 13.
Notwithstanding any provisions in this Subscription Agreement, I understand that if I am working or resident in a country other than the United States, my participation in the Plan will also be subject to the additional terms and conditions set
forth on Appendix A and any special terms and conditions for my country set forth on Appendix A. Moreover, if I relocate to one of the countries included in Appendix A, the special terms and conditions for such country will apply to me to the extent
the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. Appendix A constitutes part of this Subscription Agreement and the provisions of this Subscription Agreement
govern each Appendix (to the extent not superseded or supplemented by the terms and conditions set forth in the applicable Appendix). 
 14.
I hereby agree to be bound by the terms of the Plan. The effectiveness of this Subscription Agreement is dependent upon my eligibility to participate in the Plan.
