 Exhibit 10.4 

IMAGO BIOSCIENCES, INC. 

2021 EMPLOYEE STOCK PURCHASE PLAN 

ARTICLE 1 
 PURPOSE

 The Plan’s purpose is to assist employees of the Company and its Designated Subsidiaries in acquiring a stock ownership interest in the Company,
and to help such employees provide for their future security and to encourage them to remain in the employment of the Company and its Subsidiaries. 
 The
Plan consists of two components: the Section 423 Component and the Non-Section 423 Component. The Section 423 Component is intended to qualify as an “employee stock purchase plan” under
Section 423 of the Code and shall be administered, interpreted and construed in a manner consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes the grant of Options under the Non-Section 423 Component, which need not qualify as Options granted pursuant to an “employee stock purchase plan” under Section 423 of the Code; such Options granted under the Non-Section 423 Component shall be granted pursuant to separate Offerings containing such sub-plans, appendices, rules or procedures as may be adopted by the Administrator and
designed to achieve tax, securities laws or other objectives for Eligible Employees and the Designated Subsidiaries in locations outside of the United States. Except as otherwise provided herein, the
Non-Section 423 Component will operate and be administered in the same manner as the Section 423 Component. Offerings intended to be made under the Non-Section 423
Component will be designated as such by the Administrator at or prior to the time of such Offering. 
 For purposes of this Plan, the Administrator may
designate separate Offerings under the Plan, the terms of which need not be identical, in which Eligible Employees will participate, even if the dates of the applicable Offering Period(s) in each such Offering is identical, provided that the terms
of participation are the same within each separate Offering under the Section 423 Component as determined under Section 423 of the Code. Solely by way of example and without limiting the foregoing, the Company could, but shall not be
required to, provide for simultaneous Offerings under the Section 423 Component and the Non-Section 423 Component of the Plan. 

ARTICLE 2 
 DEFINITIONS

 As used in the Plan, the following words and phrases have the meanings specified below, unless the context clearly indicates otherwise:

compensation plan, including overtime, shift differentials, vacation pay, salaried production schedule premiums, holiday pay, jury duty pay, funeral leave pay, paid time off, military pay, prior week adjustments and weekly bonus, but excluding
bonuses and commissions, education or tuition reimbursements, imputed income arising under any group insurance or benefit program, travel expenses, business and moving reimbursements, including tax gross ups and taxable mileage allowance, income
received in connection with any stock options, restricted stock, restricted stock units or other compensatory equity awards and all contributions made by the Company or any Designated Subsidiary for the Employee’s benefit under any employee

calculated before deduction of any income or employment tax withholdings, but such amounts shall be withheld from the Employee’s net income. 

2.9 “Designated Subsidiary” means each Subsidiary, including any Subsidiary in existence on the Effective Date and any
Subsidiary formed or acquired following the Effective Date, that has been designated by the Board or Committee from time to time in its sole discretion as eligible to participate in the Plan, in accordance with Section 7.2 hereof, such
designation to specify whether such participation is in the Section 423 Component or Non-Section 423 Component. A Designated Subsidiary may participate in either the Section 423 Component or Non-Section 423 Component, but not both; provided that a Subsidiary that, for U.S. tax purposes, is disregarded from the Company or any Subsidiary that participates in the Section 423 Component shall
automatically constitute a Designated Subsidiary that participates in the Section 423 Component. The designation by the Administrator of Designated Subsidiaries and changes in such designations by the Administrator shall not require stockholder
approval. Only Subsidiary Corporations may be designated as Designated Subsidiaries for purposes of the Section 423 Component, and if an entity does not so qualify, it shall automatically be deemed to constitute a Designated Subsidiary that
participates in the Non-Section 423 Component 
 2.10 “Effective Date” means
the date immediately prior to the Public Trading Date. 
 2.11 “Eligible Employee” means, except as otherwise
provided by the Administrator or in an Offering Document, an Employee: 
 (a) who is customarily scheduled to work at least 20 hours per
week; 
 (b) whose customary employment is more than five months in a calendar year; and 

(c) who, after the granting of the Option, would not be deemed for purposes of Section 423(b)(3) of the Code to possess 5% or more of
the total combined voting power or value of all classes of stock of the Company or any Subsidiary. 

  
 2 













 For purposes of clause (c), the rules of Section 424(d) of the Code with regard to the attribution of
stock ownership shall apply in determining the stock ownership of an individual, and stock which an Employee may purchase under outstanding options shall be treated as stock owned by the Employee. 

Notwithstanding the foregoing, the Administrator may exclude from participation in the Section 423 Component as an Eligible Employee: 

(x) any Employee that is a “highly compensated employee” of the Company or any Designated Subsidiary (within the meaning of
Section 414(q) of the Code), or that is such a “highly compensated employee” (A) with compensation above a specified level, (B) who is an officer or (C) who is subject to the disclosure requirements of Section 16(a) of
the Exchange Act; or 
 (y) any Employee who is a citizen or resident of a foreign jurisdiction (without regard to whether they are also a
citizen of the United States or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Code)) if either (A) the grant of the Option is prohibited under the laws of the jurisdiction governing such Employee, or
(B) compliance with the laws of the foreign jurisdiction would cause the Section 423 Component, any Offering thereunder or an Option granted thereunder to violate the requirements of Section 423 of the Code; 

provided that any exclusion in clauses (x) or (y) shall be applied in an identical manner under each Offering to all Employees of the Company and
all Designated Subsidiaries, in accordance with Treas. Reg. § 1.423-2(e). Notwithstanding the foregoing, with respect to the Non-Section 423 Component, the first
sentence in this definition shall apply in determining who is an “Eligible Employee,” except (a) the Administrator may limit eligibility further within the Company or a Designated Subsidiary so as to only designate some Employees of
the Company or a Designated Subsidiary as Eligible Employees, and (b) to the extent the restrictions in the first sentence in this definition are not consistent with applicable local laws, the applicable local laws shall control. 

2.12 “Employee” means an individual who renders services to a Designated Subsidiary in the status of an employee, and,
with respect to the Section 423 Component, a person who is an officer or other employee (as defined in accordance with Section 3401(c) of the Code) of the Company or any Designated Subsidiary. The Company shall determine in good faith and
in the exercise of its discretion whether an individual has become or has ceased to be an Employee and the effective date of such individual’s attainment or termination of such status. For purposes of an individual’s participation in, or
other rights under the Plan, all such determinations by the Company shall be final, binding and conclusive, notwithstanding that any court of law or governmental agency subsequently makes a contrary determination. For purposes of the Plan, the
employment relationship shall be treated as continuing intact while the individual is on sick leave or other leave of absence approved by the Company or a Designated Subsidiary (which, for purposes of the Section 423 Component, must meet the
requirements of Treas. Reg. § 1.421-7(h)(2)). For purposes of the Section 423 Component, where the period of an approved leave of absence exceeds three months, or such other period specified in
Treas. Reg. § 1.421-1(h)(2), and the individual’s right to reemployment is not provided either by statute or contract, the employment relationship shall be deemed to have terminated for purposes of

reported in The Wall Street Journal or such other source as the Administrator deems reliable; 
 (b) If the Common Stock is not

prices for such date or, if there are no high bid and low asked prices for a share of Common Stock on such date, the high bid and low asked prices for a share of Common Stock on the last preceding date for which such information exists, as reported
in The Wall Street Journal or such other source as the Administrator deems reliable; or 
 (c) If the Common Stock is neither listed
on an established securities exchange, national market system or automated quotation system nor regularly quoted by a recognized securities dealer, its Fair Market Value shall be established by the Administrator in good faith (and, with respect to
the initial Offering Period of the Plan, as set forth in the Offering Document for the initial Offering Period).

2.20 “Offering” means an offer under the Plan of an Option that may be exercised during an Offering Period as further
described in Section 4 hereof. Unless otherwise specified by the Administrator, each Offering to the Eligible Employees of the Company or a Designated Subsidiary shall be deemed a separate Offering, even if the dates and other terms of the
applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by Treas. Reg. § 1.423-2(a)(1), the terms of
each separate Offering under the Section 423 Component need not be identical, provided that the terms of the Section 423 Component and an Offering thereunder together satisfy Treas. Reg. §
1.423-2(a)(2) and (a)(3). 
 2.21 “Offering Period” means such period of time commencing on such date(s) as determined by the Board or Committee, in its discretion, and with respect to which Options shall be granted to Participants. The duration and

PARTICIPATION 
 3.1
Eligibility. 
 (a) Any Eligible Employee who is employed by the Company or a Designated Subsidiary on a given Enrollment Date for an
Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of Articles 4 and 5 hereof, and, for the Section 423 Component, the limitations imposed by Section 423(b) of the Code.

 (b) No Eligible Employee shall be granted an Option under the Section 423 Component which permits the Participant’s rights to
purchase shares of Common Stock under the Plan, and to purchase stock under all other employee stock purchase plans of the Company, any Parent or any Subsidiary subject to Section 423 of the Code, to accrue at a rate which exceeds $25,000 of
fair market value of such stock (determined at the time such Option is granted) for each calendar year in which such Option is outstanding at any time. The limitation under this Section 3.1(b) shall be applied in accordance with
Section 423(b)(8) of the Code. 
 3.2 Election to Participate; Payroll Deductions 

(a) Except as provided in Sections 3.2(e) and 3.3 hereof or in an applicable Offering Document, an Eligible Employee may become a Participant
in the Plan only by means of payroll deduction. Each individual who is an Eligible Employee as of an Offering Period’s Enrollment Date may elect to participate in such Offering Period and the Plan by delivering to the Company a payroll
deduction authorization no later than the period of time prior to the applicable Enrollment Date that is determined by the Administrator, in its sole discretion. 

(b) Subject to Section 3.1(b) hereof and except as may otherwise be determined by the Administrator and/or as set forth in the Offering
Document, payroll deductions (i) shall equal at least 1% of the Participant’s Compensation as of each Payday of the Offering Period following the Enrollment Date, but not more than 15% of the Participant’s Compensation as of
each Payday of the Offering Period following the Enrollment Date; and (ii) will be expressed as a whole number percentage. Amounts deducted from a Participant’s Compensation with respect to an Offering Period pursuant to this
Section 3.2 shall be deducted each Payday through payroll deduction and credited to the Participant’s Plan Account. 
 (c) Unless
otherwise determined by the Administrator and/or as set forth in the Offering Document, following at least one payroll deduction, a Participant may decrease (to as low as zero) the amount deducted from such Participant’s Compensation only once
during an Offering Period upon ten calendar days’ prior written notice to the Company. Unless otherwise determined by the Administrator and/or as set forth in the Offering Document, a Participant may not increase the amount deducted from such
Participant’s Compensation during an Offering Period. 
 (d) Upon the completion of an Offering Period, each Participant in such
Offering Period shall automatically participate in the immediately following Offering Period at the same payroll deduction percentage or fixed amount as in effect at the termination of such Offering Period, unless such Participant delivers to the
Company a different election with respect to the successive Offering Period in accordance with Section 3.2(a) hereof, or unless such Participant becomes ineligible for participation in the Plan. 

  
 6 













 (e) Notwithstanding any other provisions of the Plan to the contrary, in non-U.S. jurisdictions where participation in the Plan through payroll deductions is prohibited, the Administrator may provide that an Eligible Employee may elect to participate through contributions to the
Participant’s account under the Plan in a form acceptable to the Administrator in lieu of or in addition to payroll deductions; provided, however, that, for any Offering under the Section 423 Component, the Administrator must determine
that any alternative method of contribution is applied on an equal and uniform basis to all Eligible Employees in the Offering. 
 (f) To
determine which Designated Subsidiaries shall participate in the Non-Section 423 Component and which shall participate in the Section 423 Component. 

3.3 Leave of Absence. During leaves of absence approved by the Company meeting the requirements of Treas. Reg. § 1.421-1(h)(2), a Participant may continue participation in the Plan by making cash payments to the Company on the Participant’s normal payday equal to the Participant’s authorized payroll deduction. 

ARTICLE 4 
 PURCHASE OF
SHARES 
 4.1 Grant of Option. The Company may make one or more Offerings under the Plan, which may be successive or overlapping
with one another, until the earlier of: (i) the date on which the shares of Common Stock available under the Plan have been sold or (ii) the date on which the Plan is suspended or terminates. The Administrator shall designate the terms and
conditions of each Offering in writing, including without limitation, the Offering Period and the Purchase Periods, as set forth in an offering document (the “Offering Document”). Each Participant shall be granted an Option
with respect to an Offering Period on the applicable Grant Date. Subject to the limitations of Section 3.1(b) hereof, the number of shares of Common Stock subject to a Participant’s Option shall be determined by dividing (a) such
Participant’s payroll deductions accumulated prior to an Exercise Date and retained in the Participant’s Plan Account on such Exercise Date by (b) the applicable Option Price; provided that, unless otherwise set forth in the
Offering Document, in no event shall a Participant be permitted to purchase during each Offering Period more than 100,000 shares of Common Stock (subject to any adjustment pursuant to Section 5.2 hereof). The Administrator and/or the Offering
Document may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that a Participant may purchase during such future Offering Periods. Each Option shall expire on the last
Exercise Date for the applicable Offering Period immediately after the automatic exercise of the Option in accordance with Section 4.3 hereof, unless such Option terminates earlier in accordance with Article 6 hereof. 

4.2 Option Price. The “Option Price” per share of Common Stock to be paid by a Participant upon exercise of the
Participant’s Option on an Exercise Date for an Offering Period shall equal 85% of the lesser of the Fair Market Value of a share of Common Stock on (a) the applicable Grant Date and (b) the applicable Exercise Date, or such other
price designated by the Administrator; provided that in no event shall the Option Price per share of Common Stock be less than the par value per share of the Common Stock; provided further, that no Option Price shall be designated by
the Administrator that would cause the Section 423 Component to fail to meet the requirements under Section 423(b) of the Code. 

  
 7 













 4.3 Purchase of Shares. 

(a) On each Exercise Date for an Offering Period, each Participant shall automatically and without any action on such Participant’s part
be deemed to have exercised the Participant’s Option to purchase at the applicable per share Option Price the largest number of whole shares of Common Stock which can be purchased with the amount in the Participant’s Plan Account. Except
as may otherwise be provided by the Administrator with respect to any Offering and/or as set forth in the Offering Document, any balance less than the per share Option Price that is remaining in the Participant’s Plan Account (after exercise of
such Participant’s Option) as of the Exercise Date shall be carried forward to the next Purchase Period or Offering Period, unless the Participant has elected to withdraw from the Plan pursuant to Section 6.1 hereof or, pursuant to
Section 6.2 hereof, such Participant has ceased to be an Eligible Employee. Any balance not carried forward to the next Purchase Period or Offering Period in accordance with the prior sentence shall be promptly refunded to the applicable
Participant. In no event shall an amount greater than or equal to the per share Option Price as of an Exercise Date be carried forward to the next Purchase Period or Offering Period. 

(b) As soon as practicable following each Exercise Date, the number of shares of Common Stock purchased by such Participant pursuant to
Section 4.3(a) hereof shall be delivered (either in share certificate or book entry form), in the Company’s sole discretion, to either (i) the Participant or (ii) an account established in the Participant’s name at a stock
brokerage or other financial services firm designated by the Company. If the Company is required to obtain from any commission or agency authority to issue any such shares of Common Stock, the Company shall seek to obtain such authority. Inability
of the Company to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance of any such shares shall relieve the Company from liability to any Participant except to refund to the
Participant such Participant’s Plan Account balance, without interest thereon. The Company may require that such shares of Common Stock be retained with a particular broker or agent for a designated period of time and/or may establish other
procedures to permit tracking of qualifying and disqualifying dispositions of such shares of Common Stock. 
 4.4 Automatic Termination
of Offering Period. If the Fair Market Value of a share of Common Stock on any Exercise Date (except the final scheduled Exercise Date of any Offering Period) is lower than the Fair Market Value of a share of Common Stock on the Grant Date for
an Offering Period, then such Offering Period shall terminate on such Exercise Date after the automatic exercise of the Option in accordance with Section 4.3 hereof, and each Participant shall automatically be enrolled in the Offering Period
that commences immediately following such Exercise Date and such Participant’s payroll deduction authorization shall remain in effect for such Offering Period. 

4.5 Transferability of Rights. An Option granted under the Plan shall not be transferable, other than by will or the applicable laws of
descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant. No option or interest or right to the Option shall be available to pay off any debts, contracts or engagements of the Participant or the
Participant’s successors in interest or shall be subject to disposition by pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any attempt at disposition of the Option shall have no effect. 

ARTICLE 5 
 PROVISIONS
RELATING TO COMMON STOCK 
 5.1 Common Stock Reserved. Subject to adjustment as provided in Section 5.2 hereof, the maximum number of shares
of Common Stock that shall be made available for sale under the Plan shall be the sum of (a) 350,000 and (b) an increase commencing on January 1, 2022 and continuing annually on the anniversary thereof through (and including)
January 1, 2031, equal to the lesser of (A) 1% of the shares of Common Stock outstanding on the last day of the immediately preceding calendar year and (B) such smaller number of shares of Common Stock as determined by the Board or the
Committee; provided,  

  
 8 













 
however, no more than 4,703,469 Shares may be issued under the Plan. Shares made available for sale under the Plan may be authorized but unissued shares, treasury shares of Common Stock,
or reacquired shares reserved for issuance under the Plan. All or any portion of such maximum number of shares may be issued under the Section 423 Component. 

5.2 Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, Merger or Asset Sale. 

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock
which have been authorized for issuance under the Plan but not yet placed under Option, as well as the price per share and the number of shares of Common Stock covered by each Option under the Plan which has not yet been exercised 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 or reclassification of the Common Stock, or any other increase or
decrease in the number of 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. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Periods then in
progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the
Administrator. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Administrator shall notify each Participant in writing prior to the New Exercise Date, that the Exercise Date for the
Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as
provided in Section 6.1 hereof or the Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof. 
 (c)
Merger or Asset Sale. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent Option
substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. If the successor corporation refuses to assume or substitute for the Option, any Offering Periods then in progress shall be shortened by setting a New
Exercise Date and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date of the Company’s proposed sale or merger. The Administrator shall notify each Participant in writing
prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such
date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof or the Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof. 

5.3 Insufficient Shares. If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with
respect to which Options are to be exercised may exceed the number of shares of Common Stock remaining available for sale under the Plan on such Exercise Date, the Administrator shall make a pro rata allocation of the shares of Common Stock
available for issuance 

  
 9 













 
on such Exercise Date in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising Options to purchase Common
Stock on such Exercise Date, and unless additional shares are authorized for issuance under the Plan, no further Offering Periods shall take place and the Plan shall terminate pursuant to Section 7.5 hereof. If an Offering Period is so
terminated, then the balance of the amount credited to the Participant’s Plan Account which has not been applied to the purchase of shares of Common Stock shall be paid to such Participant in one lump sum in cash within 30 days after such
Exercise Date, without any interest thereon. 
 5.4 Rights as Stockholders. With respect to shares of Common Stock subject to an
Option, a Participant shall not be deemed to be a stockholder of the Company and shall not have any of the rights or privileges of a stockholder. A Participant shall have the rights and privileges of a stockholder of the Company when, but not until,
shares of Common Stock have been deposited in the designated brokerage account following exercise of the Participant’s Option. 

ARTICLE 6 
 TERMINATION
OF PARTICIPATION 
 6.1 Cessation of Contributions; Voluntary Withdrawal. 

(a) A Participant may cease payroll deductions during an Offering Period and elect to withdraw from the Plan by delivering written notice of
such election to the Company in such form and at such time prior to the Exercise Date for such Offering Period as may be established by the Administrator (a “Withdrawal Election”). A Participant electing to withdraw from the
Plan may elect to either (i) withdraw all of the funds then credited to the Participant’s Plan Account as of the date on which the Withdrawal Election is received by the Company, in which case amounts credited to such Plan Account shall be
returned to the Participant in one lump-sum payment in cash within 30 days after such election is received by the Company, without any interest thereon, and the Participant shall cease to participate in the
Plan and the Participant’s Option for such Offering Period shall terminate; or (ii) exercise the Option for the maximum number of whole shares of Common Stock on the applicable Exercise Date with any remaining Plan Account balance returned
to the Participant in one lump-sum payment in cash within 30 days after such Exercise Date, without any interest thereon, and after such exercise cease to participate in the Plan. Upon receipt of a Withdrawal
Election, the Participant’s payroll deduction authorization and the Participant’s Option shall terminate. 
 (b) A
Participant’s withdrawal from the Plan shall not have any effect upon the Participant’s eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods which commence after the
termination of the Offering Period from which the Participant withdraws. 
 (c) Except as otherwise permitted by the Administrator and/or as
set forth in the Offering Document, a Participant who ceases contributions to the Plan during any Offering Period shall not be permitted to resume contributions to the Plan during that Offering Period. 

6.2 Termination of Eligibility. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, such Participant’s
Option for the applicable Offering Period shall automatically terminate, the Participant shall be deemed to have elected to withdraw from the Plan, and such Participant’s Plan Account shall be paid to such Participant or, in the case of the
Participant’s death, to the person or persons entitled thereto pursuant to applicable law, within 30 days after such cessation of being an Eligible Employee, without any interest thereon. If a Participant transfers employment from the Company
or any Designated Subsidiary participating in the Section 423 Component to any Designated Subsidiary participating in the Non-Section 423 Component, such transfer shall not be treated as a termination of


  
 10 













 
employment, but the Participant shall immediately cease to participate in the Section 423 Component; however, any contributions made for the Offering Period in which such transfer occurs
shall be transferred to the Non-Section 423 Component, and such Participant shall immediately join the then-current Offering under the Non-Section 423 Component upon the
same terms and conditions in effect for the Participant’s participation in the Section 423 Component, except for such modifications otherwise applicable for Participants in such Offering. A Participant who transfers employment from any
Designated Subsidiary participating in the Non-Section 423 Component to the Company or any Designated Subsidiary participating in the Section 423 Component shall not be treated as terminating the
Participant’s employment and shall remain a Participant in the Non-Section 423 Component until the earlier of (i) the end of the current Offering Period under the
Non-Section 423 Component, or (ii) the Enrollment Date of the first Offering Period in which the Participant is eligible to participate following such transfer. Notwithstanding the foregoing, the
Administrator may establish different rules to govern transfers of employment between companies participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable
requirements of Section 423 of the Code. 
 ARTICLE 7 

GENERAL PROVISIONS 
 7.1
Administration. 
 (a) The Plan shall be administered by the Committee, which shall be composed of members of the Board. The
Committee may delegate administrative tasks under the Plan to the services of an Agent or Employees to assist in the administration of the Plan, including establishing and maintaining an individual securities account under the Plan for each
Participant. 
 (b) It shall be the duty of the Administrator to conduct the general administration of the Plan in accordance with the
provisions of the Plan. The Administrator shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 

(i) To establish and terminate Offerings; 

(ii) To determine when and how Options shall be granted and the provisions and terms of each Offering (which need not be identical); 

(iii) To select Designated Subsidiaries in accordance with Section 7.2 hereof; 

(iv) To impose a mandatory holding period pursuant to which Participants may not dispose of or transfer shares of Common Stock purchased
under the Plan for a period of time determined by the Administrator in its discretion; and 
 (v) To construe and interpret the Plan, the
terms of any Offering and the terms of the Options and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules. The Administrator, in the
exercise of this power, may correct any defect, omission or inconsistency in the Plan, any Offering or any Option, in a manner and to the extent it shall deem necessary or expedient to administer the Plan, subject to Section 423 of the Code for
the Section 423 Component. 
 (c) The Administrator may adopt rules or procedures relating to the operation and administration of the
Plan to accommodate the specific requirements of local laws and procedures. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt 

  
 11 













 
rules and procedures regarding handling of participation elections, payroll deductions, payment of interest, conversion of local currency, payroll tax, withholding procedures and handling of
stock certificates which vary with local requirements. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Administrator under the Plan. 

(d) The Administrator may adopt sub-plans applicable to particular Designated Subsidiaries or
locations, which sub-plans may be designed to be outside the scope of Section 423 of the Code. The rules of such sub-plans may take precedence over other provisions
of this Plan, with the exception of Section 5.1 hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan. 

(e) All expenses and liabilities incurred by the Administrator in connection with the administration of the Plan shall be borne by the
Company. The Administrator may, with the approval of the Committee, employ attorneys, consultants, accountants, appraisers, brokers or other persons. The Administrator, the Company and its officers and directors shall be entitled to rely upon the
advice, opinions or valuations of any such persons. All actions taken and all interpretations and determinations made by the Administrator in good faith shall be final and binding upon all Participants, the Company and all other interested persons.
No member of the Board or Administrator shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the options, and all members of the Board or Administrator shall be fully protected by
the Company in respect to any such action, determination, or interpretation. 
 7.2 Designation of Subsidiary Corporations. The Board
or Administrator shall designate from time to time the Subsidiaries that shall constitute Designated Subsidiaries, and determine whether such Designated Subsidiaries shall participate in the Section 423 Component or Non-Section 423 Component. The Board or Administrator may designate a Subsidiary, or terminate the designation of a Subsidiary, without the approval of the stockholders of the Company. 

7.3 Reports. Individual accounts shall be maintained for each Participant in the Plan. Statements of Plan Accounts shall be made
available to Participants at least annually, which statements shall set forth the amounts of payroll deductions, the Option Price, the number of shares purchased and the remaining cash balance, if any. 

7.4 No Right to Employment. Nothing in the Plan shall be construed to give any person (including any Participant) the right to remain
in the employ of the Company, a Parent or a Subsidiary or to affect the right of the Company, any Parent or any Subsidiary to terminate the employment of any person (including any Participant) at any time, with or without cause, which right is
expressly reserved. 
 7.5 Amendment and Termination of the Plan. 

(a) The Board may, in its sole discretion, amend, suspend or terminate the Plan at any time and from time to time. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision), with respect to the Section 423 Component, or any other applicable law, regulation or stock exchange rule, the Company shall obtain stockholder approval of any such
amendment to the Plan in such a manner and to such a degree as required by Section 423 of the Code or such other law, regulation or rule. 

  
 12 













 (b) If the Administrator determines that the ongoing operation of the Plan may result in
unfavorable financial accounting consequences, the Administrator may, to the extent permitted under Section 324 of the Code, for the Section 423 Component, in its discretion and, to the extent necessary or desirable, modify or amend the
Plan to reduce or eliminate such accounting consequence including, but not limited to: 
 (i) altering the Option Price for any Offering
Period including an Offering Period underway at the time of the change in Option Price; 
 (ii) shortening any Offering Period so that the
Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the Administrator action; and 
 (iii)
allocating shares of Common Stock. 
 Such modifications or amendments shall not require stockholder approval or the consent of any Participant. 

(c) Upon termination of the Plan, the balance in each Participant’s Plan Account shall be refunded as soon as practicable after such
termination, without any interest thereon. 
 7.6 Use of Funds; No Interest Paid. All funds received by the Company by reason of
purchase of shares of Common Stock under the Plan shall be included in the general funds of the Company free of any trust or other restriction and may be used for any corporate purpose, except for funds contributed under Offerings in which the local
law of a non-U.S. jurisdiction requires that contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party for
Participants in non-U.S. jurisdictions. No interest shall be paid to any Participant or credited under the Plan, except as may be required by local law in a non-U.S.
jurisdiction. If the segregation of funds and/or payment of interest on any Participant’s account is so required, such provisions shall apply to all Participants in the relevant Offering except to the extent otherwise permitted by U.S. Treasury
Regulation Section 1.423-2(f). With respect to any Offering under the Non-Section 423 Component, the payment of interest shall apply as determined by the
Administrator (but absent any such determination, no interest shall apply). 
 7.7 Term; Approval by Stockholders. No Option may be
granted during any period of suspension of the Plan or after termination of the Plan. The Plan shall be submitted for the approval of the Company’s stockholders within 12 months after the date of the Board’s initial adoption of the Plan.
Options may be granted prior to such stockholder approval; provided, however, that such Options shall not be exercisable prior to the time when the Plan is approved by the stockholders; provided, further that if such
approval has not been obtained by the end of the 12-month period, all Options previously granted under the Plan shall thereupon terminate and be canceled and become null and void without being exercised. 

7.8 Effect Upon Other Plans. The adoption of the Plan shall not affect any other compensation or incentive plans in effect for the
Company, any Parent or any Subsidiary. Nothing in the Plan shall be construed to limit the right of the Company, any Parent or any Subsidiary (a) to establish any other forms of incentives or compensation for Employees of the Company or any
Parent or any Subsidiary, or (b) to grant or assume Options otherwise than under the Plan in connection with any proper corporate purpose, including, but not by way of limitation, the grant or assumption of options in connection with the
acquisition, by purchase, lease, merger, consolidation or otherwise, of the business, stock or assets of any corporation, firm or association. 

  
 13 













 7.9 Conformity to Securities Laws. Notwithstanding any other provision of the Plan,
the Plan and the participation in the Plan by any individual who is then subject to Section 16 of the Exchange Act shall be subject to any additional limitations set forth in any applicable exemption rule under Section 16 of the Exchange
Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, the Plan shall be deemed amended to
the extent necessary to conform to such applicable exemptive rule. 
 7.10 Notice of Disposition of Shares. Each Participant in the
Section 423 Component shall give the Company prompt notice of any disposition or other transfer of any shares of Common Stock, acquired pursuant to the exercise of an Option granted under the Section 423 Component, if such disposition or
transfer is made (a) within two years after the applicable Grant Date or (b) within one year after the transfer of such shares of Common Stock to such Participant upon exercise of such Option. The Company may direct that any certificates
evidencing shares acquired pursuant to the Plan refer to such requirement. 
 7.11 Tax Withholding. The Company or any Parent or any
Subsidiary shall be entitled to require payment in cash or deduction from other compensation payable to each Participant of any sums required by federal, state or local tax law to be withheld with respect to any purchase of shares of Common Stock
under the Plan or any sale of such shares. 
 7.12 Governing Law. The Plan and all rights and obligations thereunder shall be
construed and enforced in accordance with the laws of the State of Delaware, without regard to the conflict of law rules thereof or of any other jurisdiction. 

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

7.14 Conditions To Issuance of Shares. 

(a) Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates or make any book
entries evidencing shares of Common Stock pursuant to the exercise of an Option by a Participant, unless and until the Board or the Committee has determined, with advice of counsel, that the issuance of such shares of Common Stock is in compliance
with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any securities exchange or automated quotation system on which the shares of Common Stock are listed or traded, and the shares of Common Stock
are covered by an effective registration statement or applicable exemption from registration. In addition to the terms and conditions provided herein, the Board or the Committee may require that a Participant make such reasonable covenants,
agreements, and representations as the Board or the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. 

(b) All certificates for shares of Common Stock delivered pursuant to the Plan and all shares of Common Stock issued pursuant to book entry
procedures are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal, state, or foreign securities or other laws, rules and regulations and the rules of any securities
exchange or automated quotation system on which the shares of Common Stock are listed, quoted, or traded. The Committee may place legends on any certificate or book entry evidencing shares of Common Stock to reference restrictions applicable to the
shares of Common Stock. 
 (c) The Committee shall have the right to require any Participant to comply with any timing or other restrictions
with respect to the settlement, distribution or exercise of any Option, including a window-period limitation, as may be imposed in the sole discretion of the Committee. 

  
 14 













 (d) Notwithstanding any other provision of the Plan, unless otherwise determined by the
Committee or required by any applicable law, rule or regulation, the Company may, in lieu of delivering to any Participant certificates evidencing shares of Common Stock issued in connection with any Option, record the issuance of shares of Common
Stock in the books of the Company (or, as applicable, its transfer agent or stock plan administrator). 
 7.15 Equal Rights and
Privileges. All Eligible Employees of the Company (or of any Designated Subsidiary) granted Options pursuant to an Offering under the Section 423 Component shall have equal rights and privileges under this Plan to the extent required under
Section 423 of the Code so that the Section 423 Component qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Any provision of the Section 423 Component that is inconsistent
with Section 423 of the Code shall, without further act or amendment by the Company or the Board, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. Eligible Employees participating in the Non-Section 423 Component need not have the same rights and privileges as Eligible Employees participating in the Section 423 Component. 

7.16 Rules Particular to Specific Countries. Notwithstanding anything herein to the contrary, the terms and conditions of the Plan with
respect to Participants who are tax residents of a particular non-U.S. country or who are foreign nationals or employed in non-U.S. jurisdictions may be subject to an
addendum to the Plan in the form of an appendix or sub-plan (which appendix or sub-plan may be designed to govern Offerings under the Section 423 Component or the Non-Section 423 Component, as determined by the Administrator). To the extent that the terms and conditions set forth in an appendix or sub-plan conflict with any provisions
of the Plan, the provisions of the appendix or sub-plan shall govern. The adoption of any such appendix or sub-plan shall be pursuant to Section 7.1 above. Without
limiting the foregoing, the Administrator is specifically authorized to adopt rules and procedures, with respect to Participants who are foreign nationals or employed in non-U.S. jurisdictions, regarding the
exclusion of particular Subsidiaries from participation in the Plan, eligibility to participate, the definition of Compensation, handling of payroll deductions or other contributions by Participants, payment of interest, conversion of local
currency, data privacy security, payroll tax, withholding procedures, establishment of bank or trust accounts to hold payroll deductions or contributions. Without limiting the foregoing, the Administrator is specifically authorized to adopt rules
and procedures, with respect to Participants who are foreign nationals or employed in non-U.S. jurisdictions, regarding the exclusion of particular Subsidiaries from participation in the Plan, eligibility to
participate, the definition of Compensation, handling of payroll deductions or other contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, establishment of bank
or trust accounts to hold payroll deductions or contributions. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding the exclusion of particular Subsidiaries from
participation in the Plan, eligibility to participate, the definition of Compensation, handling of payroll deductions or other contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax,
withholding procedures, establishment of bank or trust accounts to hold payroll deductions or contributions, determination of beneficiary designation requirements, and handling of stock certificates. The Administrator also is authorized to determine
that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of a purchase right granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of purchase rights granted under the Plan or the same Offering to Employees resident solely in the U.S. To the extent any
sub-plan or appendix or other changes approved by the Administrator are inconsistent with the requirements of Section 423 of the Code or would jeopardize the
tax-qualified status of the Section 423 Component, the change shall cause the Designated Subsidiaries affected thereby to be considered Designated Subsidiaries in a separate Offering under the Non-Section 423 Component instead of the Section 423 Component. To the extent any Employee of a Designated Subsidiary in the Section 423 Component is a citizen or resident of a foreign jurisdiction


  
 15 













 
(without regard to whether they are also a U.S. citizen or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Code)) and compliance with the laws of the foreign
jurisdiction would cause the Section 423 Component, any Offering or the option to violate the requirements of Section 423 of the Code, such Employee shall be considered a Participant in a separate Offering under the Non-Section 423 Component. 
 Notwithstanding any other provisions of the Plan to the
contrary, in non-U.S. jurisdictions where participation in the Plan through payroll deductions is prohibited, the Administrator may provide that an Eligible Employee may elect to participate through
contributions to his or her account under the Plan in a form acceptable to the Administrator in lieu of or in addition to payroll deductions; provided, however, that, for any Offering under the Section 423 Component, the Administrator must
determine that any alternative method of contribution is applied on an equal and uniform basis to all Eligible Employees in the Offering. 

7.17 Transfer of Employment. A transfer of employment from one Designated Subsidiary to another shall not be treated as a termination
of employment. If a Participant transfers employment from the Company or any Designated Subsidiary participating in the Section 423 Component to a Designated Subsidiary participating in the Non-Section
423 Component, he or she shall immediately cease to participate in the Section 423 Component; however, any payroll deductions made for the Offering Period in which such transfer occurs shall be transferred to the
Non-Section 423 Component, and such Participant shall immediately join the then current Offering under the Non-Section 423 Component upon the same terms and conditions
in effect for his or her participation in the Section 423 Component, except for such modifications otherwise applicable for Participants in such Offering. A Participant who transfers employment from a Designated Subsidiary participating in the Non-Section 423 Component to the Company or any Designated Subsidiary participating in the Section 423 Component shall remain a Participant in the Non-Section 423
Component until the earlier of (i) the end of the current Offering Period under the Non-Section 423 Component, or (ii) the Enrollment Date of the first Offering Period in which he or she is eligible
to participate following such transfer. Notwithstanding the foregoing, the Administrator may establish different rules to govern transfers of employment between companies participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable requirements of Section 423 of the Code. 

7.18 Section 409A. The Section 423 Component of the Plan and the Options granted pursuant to Offerings thereunder are intended to
be exempt from the application of Section 409A. Neither the Non-Section 423 Component nor any Option granted pursuant to an Offering thereunder is intended to constitute or provide for “nonqualified
deferred compensation” within the meaning of Section 409A. Notwithstanding any provision of the Plan to the contrary, if the Administrator determines that any Option granted under the Plan may be or become subject to Section 409A or
that any provision of the Plan may cause an Option granted under the Plan to be or become subject to Section 409A, the Administrator may adopt such amendments to the Plan and/or adopt other policies and procedures (including amendments,
policies and procedures with retroactive effect), or take any other actions as the Administrator determines are necessary or appropriate to avoid the imposition of taxes under Section 409A, either through compliance with the requirements of
Section 409A or with an available exemption therefrom.
