class of securities (the “Shares”) of the Company at the Warrant Price, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant.

 ARTICLE 1. EXERCISE. 
 1.1 Method
of Exercise. Holder may exercise this Warrant by delivering a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set forth in
Article 1.2, Holder shall also deliver to the Company a check, wire transfer (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased. 

1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1, Holder may from time to time convert this
Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to Article 1.3. 
 1.3
Fair Market Value. If the Company’s common stock is traded in a public market the fair market value of each Share shall be the closing price of a Share reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company (or in 

 
the instance where the Warrant is exercised immediately prior to the effectiveness of the Company’s initial public offering, the “price to public” per share price specified in the
final prospectus relating to such offering). If the Company’s common stock is not traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. 

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant and, if applicable, the Company
receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not
so acquired. 
 1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation on surrender and cancellation of
this Warrant, the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 1.6 Treatment of Warrant
Upon Acquisition of Company. 
 1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means
(A) a sale of all or substantially all of the assets of the Company, (B) any consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, other than any such
consolidation, merger or reorganization in which the stockholders of the Company immediately prior to such consolidation, merger or reorganization, continue to hold at least a majority of the voting power of the surviving entity in substantially the
same proportions (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; or (C) any transaction or series of related transactions to which the Company is a party in
which in excess of 50% of the Company’s voting power is transferred; provided that an Acquisition shall not include any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the
Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof). 
 1.6.2 Treatment of
Warrant at Acquisition. Upon the written request of the Company, Holder agrees that, in the event of an Acquisition, either (a) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed
effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide Holder with written notice of
its request relating to the foregoing (together with such reasonable information as Holder may request In connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days
prior to the dosing of the proposed Acquisition. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares then upon exercise of this Warrant, for each
Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend occurred.

 
If the Company subdivides the Shares by reclassification or otherwise into a greater number of shares or takes any other action which increase the amount of stock into which the Shares are
convertible, the number of shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares are combined or consolidated, by reclassification or otherwise, into a
lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any reclassification, exchange, substitution, or other event that
results in a change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. The Company or its successor shall promptly issue to Holder an amendment to this
Warrant setting forth the number and kind of such new securities or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the
number and/or class of securities issuable upon exercise or conversion of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this
Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events. 
 2.3 Intentionally Omitted. 

2.4 No Impairment. The Company shall not, by amendment of its Articles or Certificate (as applicable) of Incorporation or through a
reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this
Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article 2 and in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against
impairment. Notwithstanding the foregoing, in no event shall the Company’s obligations pursuant to this Section 2.4 prohibit the Company from amending its Certificate of Incorporation with the requisite consent of its stockholders and its
board of directors as required under Delaware law. 
 2.5 Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion of this Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such fractional
share interest by paying Holder the amount computed by multiplying the fractional interest by the fair market value of a full Share. 
 2.6
Certificate as to Adjustments. Upon each adjustment of the Warrant Price, the Company shall promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate of its
Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the
series of adjustments leading to such Warrant Price.

 (ll) “Ten Percent Holder” means a person who 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. 
 3. Stock Subject to the Plan. Subject to the provisions of Section 14 of the Plan, the maximum
aggregate number of Shares that may be sold under the Plan is 27,760,000 Shares of Common Stock. The Shares may be authorized, but unissued, or reacquired Common Stock. If an award should expire or become unexercisable for any reason without having
been exercised in full, or is surrendered pursuant to an Option Exchange Program, the unpurchased Shares that were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan. In addition, any
Shares of Common Stock which are retained by the Company upon exercise of an award in order to satisfy the exercise or purchase price for such award or any withholding taxes due with respect to such exercise or purchase shall be treated as not
issued and shall continue to be available under the Plan. Shares issued under the Plan and later repurchased by the Company pursuant to any repurchase right which the Company may have shall not be available for future grant under the Plan.

 4. Administration of the Plan. 
 (a) General. The Plan shall be administered by the Board or a Committee, or a combination thereof, as determined by the Board. The Plan may be administered by different administrative bodies
with respect to different classes of Participants and, if permitted by the Applicable Laws, the Board may authorize one or more officers to make awards under the Plan. 

 (b) Committee Composition. If a Committee has been appointed pursuant to this
Section 4, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of any Committee and appoint additional members thereof, remove members (with
or without cause) and appoint new members in substitution therefor, fill vacancies (however caused) and remove all members of a Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws and, in the
case of a Committee administering the Plan in accordance with the requirements of Rule 16b-3 or Section 162(m) of the Code, to the extent permitted or required by such provisions. 

(c) 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 shall have the authority, in its discretion: 
 (i) to determine
the Fair Market Value of the Common Stock, in accordance with Section 2(q) of the Plan, provided that such determination shall be applied consistently with respect to Participants under the Plan; 

(ii) to select the Employees and Consultants to whom Options and Stock Purchase Rights may from time to time be granted; 

(iii) to determine whether and to what extent Options and Stock Purchase Rights are granted; 

(iv) to determine the number of Shares of Common Stock to be covered by each award granted; 

(v) to approve the form(s) of agreement(s) used under the Plan; 

(vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder, which terms and
conditions include but are not limited to the exercise or purchase price, the time or times when awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction
or limitation regarding any Option, Optioned Stock, Stock Purchase Right or Restricted Stock, based in each case on such factors as the Administrator, in its sole discretion, shall determine; 

(vii) to determine whether and under what circumstances an Option may be settled in cash under Section 10(c) instead of Common
Stock; 
 (viii) to implement an Option Exchange Program on such terms and conditions as the Administrator in its discretion
deems appropriate, provided that no amendment or adjustment to an Option that would materially and adversely affect the rights of any Optionee shall be made without the prior written consent of the Optionee; 

(ix) to adjust the vesting of an Option held by an Employee or Consultant as a result of a change in the terms or conditions under which
such person is providing services to the Company; 

 (x) to construe and interpret the terms of the Plan and awards granted under the Plan,
which constructions, interpretations and decisions shall be final and binding on all Participants; 
 (xi) to make any
adjustment or amendment to the Plan or to an outstanding award with or without a Participant’s consent if such adjustment or amendment is necessary to avoid the Company’s incurring adverse accounting charges; and 

(xii) in order to fulfill the purposes of the Plan and without amending the Plan, to modify grants of Options or Stock Purchase Rights
to Participants who are foreign nationals or employed outside of the United States in order to recognize differences in local law, tax policies or customs. 
 5. Eligibility. 
 (a) Recipients of Grants.
Nonstatutory Stock Options and Stock Purchase Rights may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock
Options. 
 (b) Type of Option. Each Option shall be designated in the Option Agreement as either an Incentive
Stock Option or a Nonstatutory Stock Option. 
 (c) ISO $100,000 Limitation. Notwithstanding any designation under
Section 5(b), to the extent that the aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the
Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 
 (d) No Employment Rights. The Plan shall not confer upon any Participant any right with respect to continuation of an employment or consulting relationship with the Company, nor shall it
interfere in any way with such Participant’s right or the Company’s right to terminate his or her employment or consulting relationship at any time, with or without Cause. 

6. Term of Plan. The Plan shall become effective upon its adoption by the Board of Directors. It shall continue in effect
for a term of ten (10) years unless sooner terminated under Section 16 of the Plan. 
 7. Term of
Option. The term of each Option shall be the term stated in the Option Agreement; provided that the term shall be no more than ten years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and
provided further that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement. 

 8. [Reserved.] 

9. Option Exercise Price and Consideration. 
 (a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator and set forth in the
Option Agreement, but shall be subject to the following: 
 (i) In the case of an Incentive Stock Option 

(A) granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant; or 
 (B) granted to any other Employee, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of grant. 
 (ii) In the case of a Nonstatutory Stock
Option 
 (A) granted prior to the date, if any, on which the Common Stock becomes a Listed Security to a person who is at the
time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined
by the Administrator; 
 (B) granted prior to the date, if any, on which the Common Stock becomes a Listed Security to any
other eligible person, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined by the
Administrator. 
 (C) granted on or after the date, if any, on which the Common Stock becomes a Listed Security to any eligible
person, the per share Exercise Price shall be such price as determined by the Administrator provided that if such eligible person is, at the time of the grant of such Option, a Named Executive of the Company, the per share Exercise Price shall be no
less than 100% of the Fair Market Value on the date of grant if such Option is intended to qualify as performance-based compensation under Section 162(m) of the Code. 
 (iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required above pursuant to a merger or other corporate transaction. 

(b) Permissible Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option,
including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist entirely of (1) cash; (2) check; (3) delivery of
Optionee’s promissory note with such recourse, interest, security and redemption provisions as the Administrator determines to be appropriate (subject to the provisions of Section 153 of the Delaware General Corporation Law);
(4) cancellation of indebtedness; (5) other Shares that have a Fair Market Value on the date of 

 
surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised, provided that in the case of Shares acquired, directly or indirectly, from the Company, such
Shares must have been owned by the Optionee for more than six months on the date of surrender (or such other period as may be required to avoid the Company’s incurring an adverse accounting charge); (6) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and a securities broker approved by the Company shall require to effect exercise of the Option and prompt delivery to the Company of the sale or loan proceeds required to
pay the exercise price and any applicable withholding taxes; or (7) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of
such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option exercise. 

10. Exercise of Option. 
 (a) General. 
 (i) Exercisability. Any Option granted
hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, consistent with the term of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with
respect to the Company and/or the Optionee; provided however that, if required by the Applicable Laws, any Option granted prior to the date, if any, upon which the Common Stock becomes a Listed Security shall become exercisable at the rate of at
least 20% per year over five years from the date the Option is granted. In the event that any of the Shares issued upon exercise of an Option (which exercise occurs prior to the date, if any, upon which the Common Stock becomes a Listed
Security) should be subject to a right of repurchase in the Company’s favor, such repurchase right shall, if required by the Applicable Laws, lapse at the rate of at least 20% per year over five years from the date the Option is granted.
Notwithstanding the above, in the case of an Option granted to an officer, Director or Consultant of the Company or any Parent, Subsidiary or Affiliate of the Company, the Option may become fully exercisable, or a repurchase right, if any, in favor
of the Company shall lapse, at any time or during any period established by the Administrator. The Administrator shall have the discretion to determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of
absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such leave. 
 (ii) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator may require that an Option be exercised as to a minimum number of Shares,
provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 
 (iii) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is exercised. Full payment may, as authorized by the Administrator, consist of any consideration and
method of payment allowable under Section 9(b) of the Plan, provided that the Administrator may, in its sole discretion, refuse to accept any form of consideration at the time of any Option exercise. 

 Exercise of an Option in any manner shall result in a decrease in the number of Shares that
thereafter may be 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. 
 (iv) Rights as Stockholder. Until the issuance of the Shares (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 shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is
prior to the date the stock certificate is issued, except as provided in Section 14 of the Plan. 
 (b) Termination
of Employment or Consulting Relationship. Except as otherwise set forth in this Section 10(b), the Administrator shall establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain
exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived or modified by the Administrator at any time. To the extent that the Optionee is not entitled to exercise an Option at the
date of his or her termination of Continuous Service Status, or if the Optionee (or other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified in the Option Agreement or below (as
applicable), the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option shall revert to the Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in the Option
Agreement (and subject to Section 7). 
 The following provisions (1) shall apply to the extent an Option Agreement
does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service Status, and (2) establish the minimum post-termination exercise periods that may be set forth in an Option
Agreement: 
 (i) Termination other than Upon Disability or Death or for Cause. In the event of termination of an
Optionee’s Continuous Service Status, such Optionee may exercise an Option for 30 days following such termination to the extent the Optionee was entitled to exercise it at the date of such termination. No termination shall be deemed to occur
and this Section 10(b)(i) shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or (ii) the Optionee is an Employee who becomes a Consultant. 

(ii) Disability of Optionee. In the event of termination of an Optionee’s Continuous Service Status as a result of
his or her disability (including a disability within the meaning of Section 22(e)(3) of the Code), such Optionee may exercise an Option at any time within six months following such termination to the extent the Optionee was entitled to exercise
it at the date of such termination. 

 (iii) Death of Optionee. In the event of the death of an Optionee during the
period of Continuous Service Status since the date of grant of the Option, or within thirty days following termination of Optionee’s Continuous Service Status, the Option may be exercised by Optionee’s estate or by a person who acquired
the right to exercise the Option by bequest or inheritance at any time within twelve months following the date of death, but only to the extent of the right to exercise that had accrued at the date of death or, if earlier, the date the
Optionee’s Continuous Service Status terminated. 
 (iv) Termination for Cause. In the event of termination
of an Optionee’s Continuous Service Status for Cause, any Option (including any exercisable portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee of termination of the
Optionee’s Continuous Service Status. If an Optionee’s employment or consulting relationship with the Company is suspended pending an investigation of whether the Optionee shall be terminated for Cause, all the Optionee’s rights under
any Option likewise shall be suspended during the investigation period and the Optionee shall have no right to exercise any Option. This Section 10(b)(iv) shall apply with equal effect to vested Shares acquired upon exercise of an Option
granted prior to the date, if any, upon which the Common Stock becomes a Listed Security to a person other than an officer, Director or Consultant, in that the Company shall have the right to repurchase such Shares from the Participant upon the
following terms: (A) the repurchase is made within 90 days of termination of the Participant’s Continuous Service Status for Cause at the Fair Market Value of the Shares as of the date of termination, (B) consideration for the
repurchase consists of cash or cancellation of purchase money indebtedness, and (C) the repurchase right terminates upon the effective date of the Company’s initial public offering of its Common Stock. With respect to vested Shares issued
upon exercise of an Option granted to any officer, Director or Consultant, the Company’s right to repurchase such Shares upon termination of the Participant’s Continuous Service Status for Cause shall be made at the Participant’s
original cost for the Shares and shall be effected pursuant to such terms and conditions, and at such time, as the Administrator shall determine. Nothing in this Section 10(b)(iv) shall in any way limit the Company’s right to purchase
unvested Shares issued upon exercise of an Option as set forth in the applicable Option Agreement. 
 (c) Buyout
Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made. 
 11. Stock Purchase Rights. 

(a) Rights to Purchase. When the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such
offer. In the case of a Stock Purchase Right granted prior to the date, if any, on which the Common Stock becomes a Listed Security and if required by the Applicable Laws at that time, the purchase price of Shares subject to such Stock Purchase
Rights shall not be less than 85% of the Fair Market Value of the Shares as of the date of the offer, or, in the case of a Ten Percent Holder, the price shall not be less than 100% of the Fair Market Value of the Shares as of the date of the offer.
If the Applicable Laws do not impose the requirements set forth in the preceding sentence and with respect to any 

 
Stock Purchase Rights granted after the date, if any, on which the Common Stock becomes a Listed Security, the purchase price of Shares subject to Stock Purchase Rights shall be as determined by
the Administrator. The offer to purchase Shares subject to Stock Purchase Rights shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 

(b) Repurchase Option. 
 (i) General. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser’s employment with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original purchase price paid
by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may determine, provided that with respect to a Stock Purchase Right granted
prior to the date, if any, on which the Common Stock becomes a Listed Security to a purchaser who is not an officer, Director or Consultant of the Company or of any Parent or Subsidiary of the Company, it shall lapse at a minimum rate of
20% per year if required by the Applicable Laws. 
 (ii) Termination for Cause. In the event of termination
of a Participant’s Continuous Service Status for Cause, the Company shall have the right to repurchase from the Participant vested Shares issued upon exercise of a Stock Purchase Right granted to any person other than an officer, Director or
Consultant prior to the date, if any, upon which the Common stock becomes a Listed Security upon the following terms: (A) the repurchase must be made within 90 days of termination of the Participant’s Continuous Service Status for Cause at
the Fair Market Value of the Shares as of the date of termination, (B) consideration for the repurchase consists of cash or cancellation of purchase money indebtedness, and (C) the repurchase right terminates upon the effective date of the
Company’s initial public offering of its Common Stock. With respect to vested Shares issued upon exercise of a Stock Purchase Right granted to any officer, Director or Consultant, the Company’s right to repurchase such Shares upon
termination of such Participant’s Continuous Service Status for Cause shall be made at the Participant’s original cost for the Shares and shall be effected pursuant to such terms and conditions, and at such time, as the Administrator shall
determine. Nothing in this Section 11(b)(ii) shall in any way limit the Company’s right to purchase unvested Shares as set forth in the applicable Restricted Stock Purchase Agreement. 

(c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions not
inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock Purchase Agreements need not be the same with respect to each purchaser. 

(d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to
those of a stockholder, and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior
to the date the Stock Purchase Right is exercised, except as provided in Section 14 of the Plan. 

 12. Taxes. 

(a) As a condition of the exercise of an Option or Stock Purchase Right granted under the Plan, the Participant (or in the case of the
Participant’s death, the person exercising the Option or Stock Purchase Right) shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local or foreign withholding tax obligations
that may arise in connection with the exercise of the Option or Stock Purchase Right and the issuance of Shares. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. If the Administrator allows
the withholding or surrender of Shares to satisfy a Participant’s tax withholding obligations under this Section 12 (whether pursuant to Section 12(c), (d) or (e), or otherwise), the Administrator shall not allow Shares to be
withheld in an amount that exceeds the minimum statutory withholding rates for federal and state tax purposes, including payroll taxes. 
 (b) In the case of an Employee and in the absence of any other arrangement, the Employee shall be deemed to have directed the Company to withhold or collect from his or her compensation an amount
sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of an exercise of the Option or Stock Purchase Right. 
 (c) This Section 12(c) shall apply only after the date, if any, upon which the Common Stock becomes a Listed Security. In the case of Participant other than an Employee (or in the case of an Employee
where the next payroll payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the absence of any other arrangement and to the extent permitted under the Applicable Laws, the Participant shall be
deemed to have elected to have the Company withhold from the Shares to be issued upon exercise of the Option or Stock Purchase Right that number of Shares having a Fair Market Value determined as of the applicable Tax Date (as defined below) equal
to the amount required to be withheld. For purposes of this Section 12, the Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined under the Applicable Laws (the
“Tax Date”). 
 (d) If permitted by the Administrator, in its discretion, a Participant may satisfy his or her
tax withholding obligations upon exercise of an Option or Stock Purchase Right by surrendering to the Company Shares that have a Fair Market Value determined as of the applicable Tax Date equal to the amount required to be withheld. In the case of
shares previously acquired from the Company that are surrendered under this Section 12(d), such Shares must have been owned by the Participant for more than six (6) months on the date of surrender (or such other period of time as is
required for the Company to avoid adverse accounting charges). 
 (e) Any election or deemed election by a Participant to have
Shares withheld to satisfy tax withholding obligations under Section 12(c) or (d) above shall be irrevocable as to the particular Shares as to which the election is made and shall be subject to the consent or disapproval of the
Administrator. Any election by a Participant under Section 12(d) above must be made on or prior to the applicable Tax Date. 

 (f) In the event an election to have Shares withheld is made by a Participant and the Tax
Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Participant shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is exercised but
such Participant shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 

13. Non-Transferability of Options and Stock Purchase Rights. 

(a) General. Except as set forth in this Section 13, Options and Stock Purchase Rights may not be sold, pledged,
assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option or Stock Purchase Right may be
exercised, during the lifetime of the holder of an Option or Stock Purchase Right, only by such holder or a transferee permitted by this Section 13. 
 (b) Limited Transferability Rights. Notwithstanding anything else in this Section 13, prior to the date, if any, on which the Common Stock becomes a Listed Security, the Administrator
may in its discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to
“Immediate Family” (as defined below), on such terms and conditions as the Administrator deems appropriate. Following the date, if any, on which the Common Stock becomes a Listed Security, the Administrator may in its discretion grant
transferable Nonstatutory Stock Options pursuant to Option Agreements specifying the manner in which such Nonstatutory Stock Options are transferable. “Immediate Family” means any child, stepchild, grandchild, parent, stepparent,
grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law,
brother-in-law, or sister-in-law, and shall include adoptive relationships. 

14. Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions. 

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of Shares of
Common Stock covered by each outstanding Option or Stock Purchase Right, the numbers of Shares set forth in Sections 3(a) above, and the number of Shares of Common Stock that have been authorized for issuance under the Plan but as to which no
Options or Stock Purchase Rights have yet been granted or that have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per Share of Common Stock covered by each such outstanding
Option or Stock Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or
reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the
Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares
of Common Stock subject to an Option or Stock Purchase Right. 

 (b) Dissolution or Liquidation. In the event of the dissolution or liquidation
of the Company, each Option and Stock Purchase Right will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
 (c) Corporate Transaction. In the event of a Corporate Transaction, each outstanding Option or Stock Purchase Right shall be assumed or an equivalent option or right shall be substituted by
such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), unless the Successor Corporation does not agree to assume the award or to substitute an equivalent option or right, in
which case such Option or Stock Purchase Right shall terminate upon the consummation of the transaction. 
 For purposes of this
Section 14(c), an Option or a Stock Purchase Right shall be considered assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Corporate Transaction or a Change of Control, as the case may be, each
holder of an Option or Stock Purchase Right would be entitled to receive upon exercise of the award the same number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive
upon the occurrence of the transaction if the holder had been, immediately prior to such transaction, the holder of the number of Shares of Common Stock covered by the award at such time (after giving effect to any adjustments in the number of
Shares covered by the Option or Stock Purchase Right as provided for in this Section 14); provided that if such consideration received in the transaction is not solely common stock of the Successor Corporation, the Administrator may, with the
consent of the Successor Corporation, provide for the consideration to be received upon exercise of the award to be solely common stock of the Successor Corporation equal to the Fair Market Value of the per Share consideration received by holders of
Common Stock in the transaction. 
 (d) Limitation on Payments. In the event that the vesting acceleration or
lapse of a repurchase right provided for in Section 14(c) above (x) constitutes “parachute payments” within the meaning of Section 280G of the Code, and (y) but for this Section 14(d) would be subject to the excise
tax imposed by Section 4999 of the Code (or any corresponding provisions of state income tax law), then such vesting acceleration or lapse of a repurchase right shall be either 

(A) delivered in full, or 
 (B) delivered as to such lesser extent which would result in no portion of such severance benefits being subject to excise tax under Code Section 4999, whichever amount, taking into account the
applicable federal, state and local income taxes and the excise tax imposed by Code Section 4999, results in the receipt by the Participant on an after-tax basis of the greater amount of acceleration or
lapse of repurchase rights benefits, notwithstanding that all or some portion of such benefits may be taxable under Code Section 4999. Any determination required under this Section 14(d) shall be made by the Participant. In the event that
(A) above applies, then the Participant shall be responsible for any excise taxes imposed with respect to such benefits. In the event that (B) above applies, then each benefit provided hereunder shall be proportionately reduced to the
extent necessary to avoid imposition of such excise taxes. 

 (e) Certain Distributions. In the event of any distribution to the
Company’s stockholders of securities of any other entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately
adjust the price per Share of Common Stock covered by each outstanding Option or Stock Purchase Right to reflect the effect of such distribution. 
 15. Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be the later of the date on which the Administrator
makes the determination granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. Notice of the determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of such grant. 
 16. Amendment and Termination
of the Plan. 
 (a) Authority to Amend or Terminate. The Board may at any time amend, alter, suspend or
discontinue the Plan, but no amendment, alteration, suspension or discontinuation (other than an adjustment pursuant to Section 14 above) shall be made that would materially and adversely affect the rights of any Optionee or holder of Stock
Purchase Rights under any outstanding grant, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and
to such a degree as required. 
 (b) Effect of Amendment or Termination. No amendment or termination of the Plan
shall materially and adversely affect Options or Stock Purchase Rights already granted, unless mutually agreed otherwise between the Optionee or holder of the Stock Purchase Rights and the Administrator, which agreement must be in writing and signed
by the Optionee or holder and the Company. 
 (c) Accounting Issues. Notwithstanding anything else to the contrary
in this Section 16, the Administrator may at any time amend or adjust the Plan or an outstanding award issued under the Plan without the consent of the affected Participant(s) if such amendment or adjustment is necessary to avoid the
