Section 4. 
 (b) “Applicable Laws “ means the requirements relating to the administration of equity-based
awards 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

 (c) “Award” means, individually or collectively, a grant under the
Plan of Options, Stock Appreciation Rights, Restricted Stock, or Restricted Stock Units.

(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 50% of the total voting power of the stock of the
Company, except that any change in the ownership of the stock of the Company as a result of a private financing of the Company that is approved by the Board will not be considered a Change in Control; or 

 (ii) Change in Effective Control of the Company. If the Company has a class
of securities registered pursuant to Section 12 of the Exchange Act, 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 clause (ii), if any Person is considered to be in effective control of the Company, the

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 or persons) assets from the Company that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of the assets
of the Company immediately prior to such acquisition or acquisitions. 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

or system on the day of determination, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; 

(ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair Market Value of a
Share will be the mean between the high bid and low asked prices for the Common Stock on the day of determination (or, if no bids and asks were reported on that date, as applicable, on the last trading date such bids and asks were reported), as

 3. Stock Subject to the Plan. 

(a) Stock Subject to the Plan. Subject to the provisions of Section 13, the maximum aggregate number of Shares that may be
subject to Awards and sold under the Plan is 1,200,000 Shares. The Shares may be authorized but unissued, or reacquired Common Stock. 
 (b)
Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full, is surrendered pursuant to an Exchange Program, or, with respect to Restricted Stock or Restricted Stock Units, is forfeited to or
repurchased by the Company due to the failure to vest, 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 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 have actually 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 or Restricted Stock Units are repurchased by the Company or are forfeited to the Company due to the failure to vest, such
Shares will become available for future grant under the 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, such 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 13, 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 Code Section 422 and the
Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 3(b). 

  
 -4- 

 (c) Share Reserve. The Company, during the term of this Plan, will at all
times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan. 
 4.
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) 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, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion: 

(i) to determine the Fair Market Value; 

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

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

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

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise 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 Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 

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

(vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(viii) to 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 foreign laws or for qualifying for favorable tax treatment under applicable foreign laws; 

(ix) to modify or amend each Award (subject to Section 18(c)), including but not limited to the discretionary authority to extend the
post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(d)); 

  
 -5- 

 (x) to allow Participants to satisfy withholding tax obligations in a manner prescribed in
Section 14; 
 (xi) to 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) to allow a Participant to defer the receipt of the payment of cash or the delivery of
Shares that otherwise would be due to such Participant under an Award; and 
 (xiii) to 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. 
 5.
Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, and Restricted Stock 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 in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the
term of the Option, 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. 

(c) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory
Stock Option. Notwithstanding such designation, however, 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, and calculation will be performed in accordance with Code Section 422
and Treasury Regulations promulgated thereunder. 
 (d) Term of Option. The term of each Option will be stated in the Award
Agreement; provided, however , that the term will be no more than ten (10) years from the date of grant thereof. 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. 

  
 -6- 

 (e) Option Exercise Price and Consideration. 

(i) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option will be
determined by the Administrator, but will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an Employee 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, 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. Notwithstanding the foregoing provisions of this Section 6(e)(i), 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, Code Section 424(a). 
 (ii) Waiting Period and Exercise
Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 

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

  
 -7- 

 Exercising an Option in any manner will decrease the number of Shares thereafter available,
both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (ii)
Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may
exercise his or her Option within such period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the
date of termination. In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the
date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the
time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
 (iii)
Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award
Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent the Option is vested on the date of termination. In the absence of a specified time in the Award Agreement, the Option
shall remain exercisable for twelve (12) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will
revert to the Plan. 
 (iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised
within such period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the date of death, 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 shall remain exercisable for twelve (12) months following the Participant’s termination. Unless otherwise provided by the Administrator, if at the time of death Participant is not
vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares
covered by such Option will revert to the Plan. 

  
 -8- 

 7. Stock Appreciation Rights. 

(a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right 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. 
 (b)
Number of Shares. The Administrator will have complete discretion to determine the number of Shares subject to any Award of Stock Appreciation Rights. 

(c) Exercise Price and Other Terms. The per Share exercise price for the Shares that will determine the amount of the payment to
be received upon exercise of a Stock Appreciation Right as set forth in Section 7(f) 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
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 maximum 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 by multiplying: 
 (i) the difference between the
Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) the number of Shares with respect to which the
Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be
in cash, in Shares of equivalent value, or in some combination thereof. 
 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 the
Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of
Restricted Stock until the restrictions on such Shares have lapsed. 

  
 -9- 

 (c) Transferability. Except as provided in this Section 8 or as the
Administrator determines, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the 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 the Period of Restriction or at such other time as the Administrator may
determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f)
Voting Rights. During the Period of Restriction, 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 the 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, 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, business unit, or individual
goals (including, but not limited to, continued employment or service), 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. 
 (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 in cash, Shares, or a combination of both. 

  
 -10- 

 (e) Cancellation. On the date set forth in the Award Agreement, all unearned
Restricted Stock Units will be forfeited to the Company. 
 10. Compliance With Code 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 Code 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 Code 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 Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the
grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A. 
 11.
Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of
(i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. 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. 

12. Limited Transferability of Awards. 

(a) Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, or otherwise transferred 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. 

(b) Further, until the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or after the
Administrator determines that it is, will, or may no longer be relying upon the exemption from registration under the Exchange Act as set forth in Rule 12h-1(f) promulgated under the Exchange Act, an Option,
or prior to exercise, the Shares subject to the Option, may not be pledged, hypothecated or otherwise transferred or disposed of, in any manner, including by entering into any short position, any “put equivalent position” or any “call
equivalent position” (as defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than to (i) persons who are “family
members” (as defined in Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or (ii) to an executor or guardian of the Participant upon the death or disability of the Participant. Notwithstanding the foregoing
sentence, the Administrator, in its sole discretion, may determine to permit transfers to the Company or in connection with a Change in Control or other acquisition transactions involving the Company to the extent permitted by Rule 12h-1(f). 

  
 -11- 

 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or
other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of
Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be
made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will
notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 

(c) Merger or Change in Control. In the event of a merger or 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 13(c), the Administrator will not be obligated to treat all Awards, all Awards held by a Participant, or all Awards of the same type, similarly. 

In the event that the successor corporation does not assume or substitute for the Award (or portion thereof), the Participant will fully vest
in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock
Units will lapse, and, with respect to Awards with performance-based vesting, 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 addition,
if an Option or Stock Appreciation Right is not assumed or substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be
exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

  
 -12- 

 For the purposes of this Section 13(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 Stock Appreciation Right or upon the payout of a Restricted Stock Unit, 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 Section 13(c) to the contrary, an Award that vests, is earned or
paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent;
provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 

Notwithstanding anything in this Section 13(c) to the contrary, if a payment under an Award Agreement is subject to Code
Section 409A and if the change in control definition contained in the Award Agreement does not comply with the definition of “change of control” for purposes of a distribution under Code Section 409A, then any payment of an
amount that is otherwise accelerated under this Section will be delayed until the earliest time that such payment would be permissible under Code Section 409A without triggering any penalties applicable under Code Section 409A. 

14. Tax Withholding. 
 (a)
Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an
amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof). 

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from
time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation): (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value
equal to the minimum statutory amount required to be withheld, (iii) delivering to the Company already-owned Shares having a Fair Market Value equal to the statutory amount required to be withheld, provided the delivery of such Shares will not
result in any adverse accounting consequences, as the Administrator determines in its sole discretion, or (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. The amount of the withholding requirement 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. 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. 

  
 -13- 

 15. No Effect on Employment or Service. Neither the Plan nor any Award will confer
upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such
relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 16. Date of Grant. The date of grant
of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant
within a reasonable time after the date of such grant. 
 17. Term of Plan. Subject to Section 21, the Plan will become
effective upon its adoption by the Board. Unless sooner terminated under Section 18, it will continue in effect for a term of ten (10) years from the later of (a) the effective date of the Plan, or (b) the earlier of the most
recent Board or stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 18. Amendment and
Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the
Plan. 
 (b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary
and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension
or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of
the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

19. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to 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. 
 20. Inability to Obtain Authority. The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful 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 will not have been obtained. 

  
 -14- 

 21. 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. 

22. Information to Participants. Beginning on the earlier of (i) the date that the aggregate number of Participants under this
Plan is five hundred (500) or more and the Company is relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act and (ii) the date that the Company is required to deliver
information to Participants pursuant to Rule 701 under the Securities Act, and until such time as the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, is no longer relying on the exemption
provided by Rule 12h-1(f)(1) under the Exchange Act or is no longer required to deliver information to Participants pursuant to Rule 701 under the Securities Act, the Company shall provide to each Participant
the information described in paragraphs (e)(3), (4), and (5) of Rule 701 under the Securities Act not less frequently than every six (6) months with the financial statements being not more than 180 days old and with such information
provided either by physical or electronic delivery to the Participants or by written notice to the Participants of the availability of the information on an Internet site that may be password-protected and of any password needed to access the
information. The Company may request that Participants agree to keep the information to be provided pursuant to this section confidential. If a Participant does not agree to keep the information to be provided pursuant to this section confidential,
then the Company will not be required to provide the information unless otherwise required pursuant to Rule 12h-1(f)(1) under the Exchange Act or Rule 701 of the Securities Act.

 (for California residents only, to the extent required by 25102(o)) 

This Appendix A to the Rigetti & Co, Inc. 2013 Equity Incentive Plan shall apply only to the Participants who are residents of the
State of California and who are receiving an Award under the Plan. Capitalized terms contained herein shall have the same meanings given to them in the Plan, unless otherwise provided by this Appendix A. Notwithstanding any provisions contained in
the Plan to the contrary and to the extent required by Applicable Laws, the following terms shall apply to all Awards granted to residents of the State of California, until such time as the Administrator amends this Appendix A or the Administrator
otherwise provides. 
 (a) The term of each Option shall be stated in the Award Agreement; provided, however , that the term
shall be no more than ten (10) years from the date of grant thereof. 
 (b) Unless determined otherwise by the Administrator, Awards may
not be sold, pledged, assigned, hypothecated, or otherwise transferred 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 may only be transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) as permitted by Rule 701 of the Securities Act. 

(c) If a Participant ceases to be a Service Provider, such Participant may exercise his or her Option within such period of time as specified
in the Award Agreement, which shall not be less than thirty (30) days following the date of the Participant’s termination, to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term
of the Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for three (3) months following the Participant’s termination. 

(d) 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 specified in the Award Agreement, which shall not be less than six (6) months following the date of the Participant’s termination, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the
Participant’s termination. 
 (e) If a Participant dies while a Service Provider, the Option may be exercised within such period of time
as specified in the Award Agreement, which shall not be less than six (6) months following the date of the Participant’s death, to the extent the Option is vested on the date of death (but in no event later than the expiration of the term
of such Option as set forth in the Award Agreement) by the Participant’s designated beneficiary, personal representative, 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 shall remain exercisable for twelve (12) months following the Participant’s termination. 

 (f) No Award shall be granted to a resident of California more than ten (10) years
after the earlier of the date of adoption of the Plan or the date the Plan is approved by the stockholders. 
 (g) In the event that any
dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to
prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares
covered by each outstanding Award; provided, however, that the Administrator will make such adjustments to an Award required by Section 25102(o) of the California Corporations Code to the extent the Company is relying upon the
exemption afforded thereby with respect to the Award. 
 (h) This Appendix A shall be deemed to be part of the Plan and the Administrator
shall have the authority to amend this Appendix A in accordance with Section 18 of the Plan.

 Exhibit 10.19 

EXECUTION VERSION 
 THIS WARRANT AND
THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AS SET FORTH IN SECTIONS 5.3 AND 5.5 BELOW, MAY NOT BE OFFERED, SOLD,
PLEDGED OR OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND LAWS OR IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY, SUCH OFFER, SALE, PLEDGE OR OTHER TRANSFER IS EXEMPT FROM SUCH REGISTRATION. 

AMENDED AND RESTATED WARRANT TO PURCHASE STOCK 
  

			
	Company:	  	Rigetti & Co, Inc., a Delaware corporation
		
	Number of Shares:	  	995,099
		
	Type/Series of Stock:	  	Class A Common Stock, par value $0.000001 per share, of the Company (“Common Stock”)
		
	Warrant Price:	  	$0.214 per share
		
	Issue Date:	  	March 9, 2021
		
	Amendment and Restatement Date	  	May 18, 2021
		
	Expiration Date:	  	May 18, 2031 (See also Section 5.1(b))
		
	Credit Facility:	  	This Amended and Restated Warrant to Purchase Stock (“Warrant”) is an amendment and restatement in its entirety of that certain warrant instrument originally issued on the Issue Date (the “Prior Warrant”),
in connection with that certain Loan and Security Agreement, dated as March 9, 2021, between Trinity Capital Inc., a Maryland corporation with an office located at 3075 W. Ray Road, Suite 525, Chandler, AZ 85226 (“Trinity”), as
lender, and the Company, as borrower (as amended, restated, or otherwise modified from time to time, the “Loan Agreement”). Trinity and the Company agree that the Prior Warrant is hereby amended and restated in its entirety as set
forth in this Warrant and the Prior Warrant shall cancelled and of no further force and effect.

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, Trinity (together with any successor or
permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid and non-assessable shares (the
“Shares”) of the above- stated Type/Series of Stock (the “Class”) of the above-named company (the “Company”) at the above-stated Warrant Price, all as set forth above and as adjusted pursuant to
SECTION 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 
 SECTION 1
EXERCISE. 
 1.1 Method of Exercise/Exchange. Holder may at any time and from time to time exercise this Warrant, in whole or
in part, by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise/Exchange in substantially the form attached hereto as Appendix 1 and, unless Holder is exchanging this Warrant pursuant to a cashless
exchange set forth in Section 1.2 a check, wire transfer of same- day funds (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 Cashless Exchange. In lieu of payment of the aggregate Warrant Price in the manner as specified in Section 1.1 above, but
otherwise in accordance with the requirements of Section 1.1, Holder shall have the right to exchange this Warrant or any portion hereof for a number of Shares equal to the value of this Warrant, or portion hereof as to which this Warrant is
being exchanged. Thereupon, the Company shall issue to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula: 

X = Y(A-B)/A 

 where: 

X = the number of Shares to be issued to the Holder; 

Y = the number of Shares with respect to which this Warrant is being exchanged (inclusive of the Shares surrendered to the Company in
satisfaction of the aggregate Warrant Price); 
 A =     the Fair Market Value (as determined pursuant to
Section 1.3 below) of one Share; and 
 B =     the Warrant Price. 

1.3 Fair Market Value. If the Common Stock is then traded or quoted on a nationally recognized securities
exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”) and the Class is Common Stock, the fair market value of a
Share shall be the closing price or last sale price of a share of Common Stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise/Exchange to the Company. If the
Common Stock is not traded in a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in its reasonable good faith judgment. 

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or exchanges this Warrant in the manner set forth in
Section 1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise and, if this Warrant has not been fully exercised or exchanged and has not expired, a new warrant of like
tenor representing the Shares not so acquired. 
 1.5 Replacement of Warrant. 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, substance and amount to the Company or, in the case of
mutilation, on surrender of this Warrant to the Company for cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount. 

1.6 Treatment of Warrant Upon Acquisition of
Company. 
 (a) Acquisition. For the purpose of this Warrant, “Acquisition” means a Liquidation Event (as
defined in the Company’s Fifth Amended and Restated Certificate of Incorporation, as amended and/or restated from time to time), other than a liquidation, dissolution or winding up of the Company. 

(b) Treatment of Warrant in Cash/Public Acquisition. In the event of an Acquisition in which the consideration to be
received by the Company’s stockholders consists solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public Acquisition”), and the fair market value of one Share as
determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date immediately prior to such Cash/Public Acquisition, and Holder has not exercised this Warrant pursuant to Section 1.1 above as to
all Shares, then this Warrant shall automatically be deemed to be exchanged pursuant to Section 1.2 above as to all Shares effective immediately prior to and contingent upon the consummation of a Cash/Public Acquisition. In connection with such
exchange, Holder shall be deemed to have restated each of the representations and warranties in Section 4 of the Warrant as the date thereof and the Company shall promptly notify the Holder of the number of Shares (or such other securities)
issued upon exercise or exchange. In the event of a Cash/Public Acquisition where the fair market value of one Share as determined in accordance with Section 1.3 above would be less than the Warrant Price in effect immediately prior to such
Cash/Public Acquisition, then this Warrant will expire immediately prior to the consummation of such Cash/Public Acquisition. 

  
 2 

 (c) Sale Right in a Cash Acquisition. Notwithstanding the foregoing, in connection
with an Acquisition in which the consideration to be received by the Company’s stockholders is primarily cash, Holder shall have the right in lieu of the foregoing to exchange this Warrant or any portion hereof for a lump-sum cash payment equal to the value of this Warrant, or portion hereof as to which this Warrant is being exchanged. Any payments made by the Company to the Holder pursuant to this Warrant shall be made without
any deduction or withholding for or on account of taxes or otherwise. Thereupon, the Company shall pay to the Holder such lump- sum cash payment equal to the product of “X” multiplied by “A,” each as determined in accordance with
Section 1.2 above. In the event an agreement for an Acquisition provides for escrowed or contingent payments or other payments over time, Holder shall receive payments only at the time that such payments are actually made to the Company’s
stockholders, and Holder’s payments shall be calculated based upon the actual amounts so paid and subject to the same obligations as Holder otherwise would have as a stockholder. 

(d) Treatment of Warrant in Other Acquisitions. Upon the closing of any Acquisition other than a Cash/Public Acquisition defined above,
the Company shall cause the acquiring, surviving or successor entity to assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares
issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant;
provided, however, that if the fair market value of one Share as determined in accordance with Section 1.3 above in such Acquisition is greater than one and one-half times the Warrant Price
then in effect then the acquiring, surviving or successor entity may elect not to assume the obligations of this Warrant and this Warrant shall terminate upon the consummation of such Acquisition, provided further, however, that the
acquiring, surviving or successor entity and the Company shall give the Holder notice in accordance with Section 3.3(d) of this Warrant and reasonable opportunity to exercise or exchange this Warrant prior to the consummation of such
Acquisition, and in any event the provisions of Section 5.1(b) shall be applicable upon such expiration. 
 (e) As used in this
Warrant, “Marketable Securities” means securities meeting all of the following requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required reports and other information under the Securities Act of 1933, as amended (the “Act”) and the Exchange Act;
(ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were Holder to exercise this Warrant on or prior to the closing thereof is then traded in Trading Market;
and (iii) Holder would be able to publicly re-sell, within six months following the closing of such Acquisition, all of the issuer’s shares and/or other securities that would be received by Holder in
such Acquisition were Holder to exercise this Warrant in full on or prior to the closing of such Acquisition. 
 SECTION 2
ADJUSTMENTS TO THE SHARES AND WARRANT PRICE. 
 2.1
Stock Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the Class payable in Common Stock or other securities or property (other than cash), then upon exercise of this
Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would have received had Holder owned the Shares of record as of the date the dividend or
distribution occurred. If the Company subdivides the outstanding shares of the Class by reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant
Price shall be proportionately decreased, provided the aggregate purchase price shall remain the same. If the outstanding shares of the Class 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, provided the aggregate purchase price shall remain the same. 

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Class are
reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and
series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, provided the aggregate purchase price shall remain the same and subject to further adjustment thereafter from
time to time in accordance with the provisions of this Warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations, substitutions, replacements or other similar events. 

  
 3 

 2.3 No Fractional Share. No fractional Share shall be issuable upon exercise 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 of the Warrant, the Company shall eliminate such fractional Share interest by paying Holder in
cash the amount computed by multiplying the fractional interest by (a) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (b) the then-effective Warrant Price. 

2.4 Notice/Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the Company, at
the Company’s expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, Class and/or number of Shares and facts upon which such adjustment is based. The Company shall, upon written
request from Holder, furnish Holder with a certificate of its Chief Executive Officer or Chief Financial Officer, including computations of such adjustment and the Warrant Price, Class and number of Shares in effect upon the date of such
adjustment. 
 SECTION 3 REPRESENTATIONS AND COVENANTS OF THE COMPANY. 

3.1 Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder as follows: 

(a) The initial Warrant Price referenced on the first page of this Warrant is not greater than the price per share at which shares of the

upon the exercise of this Warrant, and any warrants issued in substitution for or replacement of this Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable, and free
of any taxes, liens, charges and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. The Company covenants that it shall at all times cause to be reserved and kept available out
of its authorized and unissued capital stock such number of shares of Common Stock and other securities as will be sufficient to permit the exercise in full of this Warrant. 

(c) The Company’s capitalization table attached hereto as Schedule 1 is true and complete, in all material respects, as of the Issue
Date. 
 (d) The Company (i) has been duly incorporated and is validly existing as a corporation in good standing under the laws of
Delaware, with full corporate power and authority to own or lease, as the case may be, and to operate its properties and conduct its business as presently conducted, and (ii) is duly qualified to do business as a foreign corporation and is in
good standing under the laws of each jurisdiction which requires such qualification, except in the case of clause (ii) above, to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to result in
(i) a material adverse effect on the validity or enforceability of this Warrant, (ii) a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Company, or (iii) a material adverse
effect on the Company’s ability to perform in any material respect its obligations under this Warrant (any of (i), (ii) or (iii)) (a “Material Adverse Effect”). 

(e) The Company has all requisite corporate power and authority, and has taken all requisite corporate action, to execute and deliver this
Warrant, sell and issue the Shares and carry out and perform all of its obligations under this Warrant, and without limiting the foregoing, the Company hereby agrees that the Company shall all times have authorized and reserved the number of Shares
needed to provide for the exercise of the rights then represented by this Warrant. If at any time the Company does not have a sufficient number of Shares authorized and available, then the Company shall call and hold a special meeting of its
stockholders within 60 days of that time for the sole purpose of increasing the number of authorized Shares to a sufficient number. This Warrant constitutes the legal, valid and binding obligation of the Company, enforceable in accordance with its
terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally and (ii) as limited by equitable principles generally,
including any specific performance. 

  
 4 

 (f) No consent, approval, order or authorization of, or registration, qualification,
designation, declaration or filing with, any federal, state, or local governmental authority on the part of the Company is required in connection with the consummation of the transactions contemplated by this Warrant except for the filing of a Form

which shares of Common Stock are offered and/or sold, which compliance will be effected in accordance with such laws. 
 (g) Neither the
execution, delivery or performance of this Warrant by the Company nor the consummation of any of the transactions contemplated thereby (including, without limitation, the issuance and sale by the Company of the Shares) will conflict with, result in
a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, (i) the charter or by-laws of the Company, (ii) the terms of any
indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company is a party or bound or to which its or their property is subject, or
(iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of
its properties, except in the case of clauses (ii) and (iii) above, for any conflict, breach or violation of, or imposition that would not, individually or in the aggregate, have a Material Adverse Effect. 

(h) Neither the Company nor any Person acting on its behalf, has engaged in any form of general solicitation or general advertising (within
the meaning of Regulation D promulgated under the Securities Act) in connection with the offer or sale of this Warrant. 
 (i) Neither of
the Company or any Person acting on its behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any Company security, under circumstances that would adversely affect reliance by the Company on
Section 4(a)(2) of the Securities Act or require registration of this Warrant under the Securities Act or cause this Warrant to be integrated with prior offerings by the Company for purposes of the Securities Act. 

3.2 Reporting. So long as this Warrant has not been terminated or fully exercised, and after the financial obligations under the Loan
Agreement have been fully repaid in cash, the Company shall deliver to the Holder:

 SECTION 4 REPRESENTATIONS AND
WARRANTIES OF THE HOLDER. 
 The Holder represents and warrants to the Company as
follows: 
 4.1 Purchase for Own Account. This Warrant and the securities to be acquired upon exercise of this Warrant by Holder are
being acquired for investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents that it has not been formed for the specific purpose
of acquiring this Warrant or the Shares. 
 4.2 Disclosure of Information. Holder is aware of the Company’s business affairs and
financial condition and has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder
further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company
possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. 

4.3 Investment Experience. Holder understands that the purchase of this Warrant and its underlying securities involves substantial risk.
Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying securities and has such knowledge
and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business relationship with the Company and
certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. 

  
 6 

 4.4 Accredited Investor Status. Holder is an “accredited investor” within
the meaning of Regulation D promulgated under the Act. 
 4.5 The Act. Holder understands that this Warrant and the Shares issuable
upon exercise hereof have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. Holder
understands that this Warrant and the Shares issued upon any exercise hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and
qualification are otherwise available. Holder is aware of the provisions of Rule 144 promulgated under the Act. 
 4.6 No Voting or Other
Stockholder Rights. Holder, as a Holder of this Warrant, will not have any voting rights or any other rights as stockholder of the Company until the exercise of this Warrant. 

4.7 Voting Agreement. Upon any exercise of the Warrant, Holder agrees to be bound by that certain Amended and Restated Voting Agreement
dated as of February 18, 2020 by and among the Company and certain of the Company’s stockholders, as the same may be amended from time to time (the “Voting Agreement”) and shall execute a counterpart signature page and/or
joinder agreement necessary for Holder to become party to such Voting Agreement. 
 4.8 Market
Stand-off Agreement. The Holder agrees that the shares subject to this Warrant shall be subject to the market standoff provisions in Section 2.10 of that certain Amended and Restated Investors’
Rights Agreement dated February 18, 2020, as the same may be amended from time to time (the “Market Standoff Provision”); provided that Holder shall not be subject to any amendment to the Market Standoff Provision
after the date hereof without Holder’s written consent if such amendment would adversely affect Holder in a manner disproportionate to any adverse effect such amendment would have on other stockholders of the Company subject to the Market
Standoff Provision at the time of such amendment. 
 SECTION 5 MISCELLANEOUS. 

5.1 Term and Automatic Exchange Upon Expiration 

(a) Term. Subject to the provisions of Section 1.6 above, this Warrant is exercisable in whole or in part at any time and from
time to time on or before 6:00 P.M. Pacific time, on the Expiration Date and shall be void thereafter; 
 (b) Automatic
Cashless Exchange upon Expiration. In the event that, upon the Expiration Date, the fair market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance
with Section 1.3 above is greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exchanged pursuant to Section 1.2 above as to all Shares (or such other
securities) for which it shall not previously have been exercised, and the Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities) issued upon such exchange to Holder. 

5.2 Legends. The Shares shall be imprinted with a legend in substantially the following form: 

THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR

 5.3 Compliance with Securities Laws
on Transfer. This Warrant and the Shares issuable upon exercise of this Warrant may not be transferred or assigned in whole or in part except in compliance with applicable federal and state securities laws by the transferor
and the transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide
an opinion of counsel if the transfer is to any affiliate of Holder, provided that any such transferee is an “accredited investor” as defined in Regulation D promulgated under the Act. Additionally, the Company shall also not
require an opinion of counsel if there is no material question as to the availability of Rule 144 promulgated under the Act. 
 5.4
Further Assurances. The Company will not increase the par value of any Shares above the Warrant Price then in effect, and will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue
