 Exhibit 10.6 

RENEO PHARMACEUTICALS, INC. 

2021 EMPLOYEE STOCK PURCHASE PLAN 

ADOPTED BY THE BOARD OF DIRECTORS:
MARCH 10, 2021 
 APPROVED BY THE STOCKHOLDERS:
APRIL 4, 2021 
 IPO DATE: ______________, 2021 

 

	1.        	 GENERAL; PURPOSE. 



(a)        The Plan provides a means by which Eligible Employees of the Company
and certain designated Related Corporations may be given an opportunity to purchase shares of Common Stock. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan. In addition,
the Plan permits the Company to grant a series of Purchase Rights to Eligible Employees that do not meet the requirements of an Employee Stock Purchase Plan. 

(b)        The Plan includes two components: a 423 Component and a Non-423 Component. The Company intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as an Employee Stock Purchase Plan. The provisions of the 423 Component, accordingly, will
be construed in a manner that is consistent with the requirements of Section 423 of the Code. Except as otherwise provided in the Plan or determined by the Board, the Non-423 Component will operate and be
administered in the same manner as the 423 Component. 
 (c)        The
Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related
Corporations. 
  

	2.        ADMINISTRATION.	 



(a)        The Board or the Committee will administer the Plan. References
herein to the Board shall be deemed to refer to the Committee except where context dictates otherwise. 

(b)        The Board will have the power, subject to, and within the
limitations of, the express provisions of the Plan: 
 (i)        To
determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical). 

(ii)        To designate from time to time (A) which Related Corporations
of the Company will be eligible to participate in the Plan, (B) whether such Related Corporations will participate in the 423 Component or the Non-423 Component, and (C) to the extent that the
Company makes separate Offerings under the 423 Component, in which Offering the Related Corporations in the 423 Component will participate. 

(iii)        To construe and interpret the Plan and Purchase Rights, and to
establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make
the Plan fully effective. 

  
 1 













 (iv)        To settle all
controversies regarding the Plan and Purchase Rights granted under the Plan. 

(v)         To suspend or terminate the Plan at any time as provided in
Section 12. 
 (vi)        To amend the Plan at any time as provided in
Section 12. 
 (vii)        Generally, to exercise such powers and to
perform such acts as it deems necessary or expedient to promote the best interests of the Company and its Related Corporations and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan with respect to the 423 Component.

 (viii)        To adopt such rules, procedures and sub-plans as are necessary or appropriate to permit or facilitate participation in the Plan by Employees who are foreign nationals or employed or located outside the United States. Without limiting the generality
of, and consistent with, the foregoing, the Board specifically is authorized to adopt rules, procedures, and sub-plans regarding, without limitation, eligibility to participate in the Plan, the definition of
eligible “earnings,” handling and making of Contributions, establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary
designation requirements, withholding procedures and handling of share issuances, any of which may vary according to applicable requirements, and which, if applicable to a Related Corporation designated for participation in the Non-423 Component, do not have to comply with the requirements of Section 423 of the Code. 

(c)        The Board may delegate some or all of the administration of the Plan
to a Committee or Committees. If administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee,
including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan and any Offering Document to the Board will thereafter be to the Committee or subcommittee),
subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any
time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the final power to determine all questions of policy and expediency that
may arise in the administration of the Plan. 
 (d)        All
determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 

 

	3.        	 SHARES OF COMMON STOCK SUBJECT
TO THE PLAN. 



(a)        Subject to the provisions of Section 11(a) relating to
Capitalization Adjustments, the maximum number of shares of Common Stock that may be issued under the Plan will not exceed 243,058 shares of Common Stock, plus the number of shares of Common Stock that are automatically added on January 1st of each year for a period of up to ten years, commencing on the first January 1 following the year in which the IPO Date occurs and ending on (and including) January 1, 2031, in an amount
equal to the lesser of (i) 1% of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year, and (ii) 729,174 shares of Common Stock. Notwithstanding
the foregoing, the Board may act prior to the first day of any calendar year to provide that there will be no January 1st increase in the share reserve for such calendar year or that the increase
in the share reserve for such calendar year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. For the avoidance of doubt, up to the maximum number of shares of Common Stock reserved
under this Section 3(a) may be used to satisfy purchases of Common Stock under the 423 Component and 

  
 2 













 
any remaining portion of such maximum number of shares may be used to satisfy purchases of Common Stock under the Non-423 Component. 

(b)        If any Purchase Right granted under the Plan terminates without
having been exercised in full, the shares of Common Stock not purchased under such Purchase Right will again become available for issuance under the Plan. 

(c)        The stock purchasable under the Plan will be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market. 

4.        GRANT OF PURCHASE RIGHTS;
OFFERING. 
 (a)        The Board may from time to time
grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain
such terms and conditions as the Board will deem appropriate, and, with respect to the 423 Component, will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and
privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation
of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of
the provisions contained in Sections 5 through 8, inclusive. 
 (b)        If
a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise indicates in forms delivered to the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a
Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or
a later-granted Purchase Right if different Purchase Rights have identical exercise prices) will be exercised. 

(c)        The Board will have the discretion to structure an Offering so that
if the Fair Market Value of a share of Common Stock on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for that Offering, then
(i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase
Period. 
 5.        ELIGIBILITY. 

(a)        Purchase Rights may be granted only to Employees of the Company or,
as the Board may designate in accordance with Section 2(b), to Employees of a Related Corporation. Except as provided in Section 5(b) or as required by Applicable Law, an Employee will not be eligible to be granted Purchase Rights unless,
on the Offering Date, the Employee has been in the employ of the Company or the Related Corporation, as the case may be, for such continuous period preceding such Offering Date as the Board may require, but in no event will the required period of
continuous employment be equal to or greater than two years. In addition, the Board may (unless prohibited by law) provide that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such
Employee’s customary employment with the Company or the Related Corporation is more than 20 hours per week and more than five months per calendar year or such other criteria as the Board may determine consistent with Section 423 of the
Code with respect to the 423 Component. The Board may also exclude from participation in the 

  
 3 













 
Plan or any Offering Employees who are “highly compensated employees” (within the meaning of Section 423(b)(4)(D) of the Code) of the Company or a Related Corporation or a subset
of such highly compensated employees. 
 (b)        The Board may provide
that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter,
receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that Offering, as
described herein, except that: 
 (i)        the date on which such Purchase
Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right; 

(ii)        the period of the Offering with respect to such Purchase Right
will begin on its Offering Date and end coincident with the end of such Offering; and 

(iii)        the Board may provide that if such person first becomes an
Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Purchase Right under that Offering. 

(c)        No Employee will be eligible for the grant of any Purchase Rights
if, immediately after any such Purchase Rights are granted, such Employee owns stock possessing five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of
this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase Rights and options will be treated as stock
owned by such Employee. 
 (d)        As specified by Section 423(b)(8)
of the Code, an Eligible Employee may be granted Purchase Rights only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible
Employee’s rights to purchase stock of the Company or any Related Corporation to accrue at a rate which, when aggregated, exceeds US $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with
respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time. 

(e)        Officers of the Company and any designated Related Corporation, if
they are otherwise Eligible Employees, will be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may (unless prohibited by law) provide in an Offering that Employees who are highly compensated Employees
within the meaning of Section 423(b)(4)(D) of the Code will not be eligible to participate. 

(f)        Notwithstanding anything in this Section 5 to the contrary, in
the case of an Offering under the Non-423 Component, an Eligible Employee (or group of Eligible Employees) may be excluded from participation in the Plan or an Offering if the Board has determined, in its sole
discretion, that participation of such Eligible Employee(s) is not advisable or practical for any reason. 
  

	6.        	 PURCHASE RIGHTS; PURCHASE PRICE.



 (a)        On each Offering Date, each Eligible
Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock 

  
 4 













 
purchasable either with a percentage or with a maximum dollar amount, as designated by the Board, but in either case not exceeding 20% of such Employee’s earnings (as defined by the Board in
each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering. 

(b)        The Board will establish one or more Purchase Dates during an
Offering on which Purchase Rights granted for that Offering will be exercised and shares of Common Stock will be purchased in accordance with such Offering. 

(c)        In connection with each Offering made under the Plan, the Board may
specify (i) a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants
pursuant to such Offering and/or (iii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of shares of Common Stock issuable upon
exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of the
shares of Common Stock (rounded down to the nearest whole share) available will be made in as nearly a uniform manner as will be practicable and equitable. 

(d)        The purchase price of shares of Common Stock acquired pursuant to
Purchase Rights will be not less than the lesser of: 
 (i)         an
amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or 

(ii)        an amount equal to 85% of the Fair Market Value of the shares of
Common Stock on the applicable Purchase Date. 
 7.        PARTICIPATION;
WITHDRAWAL; TERMINATION. 
 (a)        An
Eligible Employee may elect to participate in an Offering and authorize payroll deductions as the means of making Contributions by completing and delivering to the Company, within the time specified in the Offering, an enrollment form provided by
the Company. The enrollment form will specify the amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan
and will be deposited with the general funds of the Company except where Applicable Law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first payroll
occurring on or after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering).
If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If required under Applicable Law or if specifically provided in the Offering, in addition to or instead of making
Contributions by payroll deductions, a Participant may make Contributions through the payment by cash, check or wire transfer prior to a Purchase Date. 

(b)        During an Offering, a Participant may cease making Contributions and
withdraw from the Offering by delivering to the Company a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such Participant’s Purchase Right in that
Offering will immediately terminate and the Company will distribute as soon as practicable to such Participant all of his or her accumulated but unused Contributions and such Participant’s 

  
 5 













 
Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon his or her eligibility to participate in any other Offerings
under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings. 

(c)        Unless otherwise required by Applicable Law, Purchase Rights granted
pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation period required by law) or (ii) is
otherwise no longer eligible to participate. The Company will distribute as soon as practicable to such individual all of his or her accumulated but unused Contributions. 

(d)        Unless otherwise determined by the Board, a Participant whose
employment transfers or whose employment terminates with an immediate rehire (with no break in service) by or between the Company and a Related Corporation that has been designated for participation in the Plan will not be treated as having
terminated employment for purposes of participating in the Plan or an Offering; however, if a Participant transfers from an Offering under the 423 Component to an Offering under the Non-423 Component, the
exercise of the Participant’s Purchase Right will be qualified under the 423 Component only to the extent such exercise complies with Section 423 of the Code. If a Participant transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the Purchase Right will remain non-qualified under the
Non-423 Component. The Board may establish different and additional rules governing transfers between separate Offerings within the 423 Component and between Offerings under the 423 Component and Offerings
under the Non-423 Component. 

(e)        During a Participant’s lifetime, Purchase Rights will be
exercisable only by such Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10. 

(f)        Unless otherwise specified in the Offering or as required by
Applicable Law, the Company will have no obligation to pay interest on Contributions. 
  

	8.        	 EXERCISE OF PURCHASE RIGHTS.



 (a)        On each Purchase Date, each
Participant’s accumulated Contributions will be applied to the purchase of shares of Common Stock, up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering, at the purchase price specified in the
Offering. No fractional shares will be issued unless specifically provided for in the Offering. 

(b)        Unless otherwise provided in the Offering, if any amount of
accumulated Contributions remains in a Participant’s account after the purchase of shares of Common Stock on the final Purchase Date of an Offering, then such remaining amount will not roll over to the next Offering and will instead be
distributed in full to such Participant after the final Purchase Date of such Offering without interest (unless otherwise required by Applicable Law). 

(c)        No Purchase Rights may be exercised to any extent unless the shares
of Common Stock to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable U.S. federal and state, foreign and other
securities, exchange control and other laws applicable to the Plan. If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the
Purchase Date will be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than 27 months from the Offering
Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are not registered and 

  
 6 













 
the Plan is not in material compliance with all Applicable Laws, as determined by the Company in its sole discretion, no Purchase Rights will be exercised and all accumulated but unused
Contributions will be distributed to the Participants without interest (unless the payment of interest is otherwise required by Applicable Law). 
  

	9.        	 COVENANTS OF THE COMPANY.



 The Company will seek to obtain from each U.S. federal or state, foreign or other regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock thereunder unless the Company determines, in its sole discretion, that doing so would cause
the Company to incur costs that are unreasonable. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale
of Common Stock under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Common Stock upon exercise of such Purchase Rights. 

 

	10.      	 DESIGNATION OF BENEFICIARY. 



(a)        The Company may, but is not obligated to, permit a Participant to
submit a form designating a beneficiary who will receive any shares of Common Stock and/or Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are delivered to the
Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company. 

(b)         If a Participant dies, and in the absence of a valid beneficiary
designation, the Company will deliver any shares of Common Stock and/or Contributions to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of the Company), the
Company, in its sole discretion, may deliver such shares of Common Stock and/or Contributions, without interest (unless the payment of interest is otherwise required by Applicable Law), to the Participant’s spouse, dependents or relatives, or
if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 
  

	11.      	 ADJUSTMENTS UPON CHANGES IN
COMMON STOCK; CORPORATE TRANSACTIONS. 



(a)        In the event of a Capitalization Adjustment, the Board will
appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase
automatically each year pursuant to Section 3(a), (iii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that
are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive. 

(b)        In the event of a Corporate Transaction, then: (i) any
surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration
paid to the stockholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute
similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common Stock (rounded down to the nearest 

  
 7 













 
whole share) within ten business days prior to the Corporate Transaction under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase. 

 

	12.      	 AMENDMENT, TERMINATION OR SUSPENSION
OF THE PLAN. 



(a)        The Board may amend the Plan at any time in any respect the Board
deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, stockholder approval will be required for any amendment of the Plan for which stockholder approval is required by Applicable Law.

 (b)        The Board may suspend or terminate the Plan at any time. No
Purchase Rights may be granted under the Plan while the Plan is suspended or after it is terminated. 
 Any benefits,
privileges, entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with
the consent of the person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and
the regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by the
Board, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that
the Purchase Right and/or the Plan complies with the requirements of Section 423 of the Code with respect to the 423 Component or with respect to other Applicable Laws. Notwithstanding anything in the Plan or any Offering Document to the
contrary, the Board will be entitled to: (i) establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars; (ii) permit Contributions in excess of the amount designated by a Participant in order to
adjust for mistakes in the Company’s processing of properly completed Contribution elections; (iii) establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the
purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Contributions; (iv) amend any outstanding Purchase Rights or clarify any ambiguities regarding the terms of any Offering to
enable the Purchase Rights to qualify under and/or comply with Section 423 of the Code with respect to the 423 Component; and (v) establish other limitations or procedures as the Board determines in its sole discretion advisable that are
consistent with the Plan. The actions of the Board pursuant to this paragraph will not be considered to alter or impair any Purchase Rights granted under an Offering as they are part of the initial terms of each Offering and the Purchase Rights
granted under each Offering. 
  

	13.      	 TAX QUALIFICATION; TAX WITHHOLDING.



 (a)        Although the Company may endeavor to
(i) qualify a Purchase Right for special tax treatment under the laws of the United States or jurisdictions outside of the United States or (ii) avoid adverse tax treatment, the Company makes no representation to that effect and expressly
disavows any covenant to maintain special or to avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan. The Company will be unconstrained in its corporate activities without regard to the potential negative tax
impact on Participants. 
 (b)        Each Participant will make
arrangements, satisfactory to the Company and any applicable Related Corporation, to enable the Company or the Related Corporation to fulfill any withholding obligation for Tax-Related Items. Without
limitation to the foregoing, in the Company’s sole discretion and subject to Applicable Law, such withholding obligation may be satsified in whole or in part by (i) 

  
 8 













 
withholding from the Participant’s salary or any other cash payment due to the Participant from the Company or a Related Corporation; (ii) withholding from the proceeds of the sale of
shares of Common Stock acquired under the Plan, either through a voluntary sale or a mandatory sale arranged by the Company; or (iii) any other method deemed acceptable by the Board. 

14.      EFFECTIVE DATE OF PLAN. 

The Plan will become effective immediately prior to and contingent upon the IPO Date. No Purchase Rights will be exercised
unless and until the Plan has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the Plan is adopted (or if required under Section 12(a) above, materially amended) by the Board.

 15.      MISCELLANEOUS PROVISIONS. 

(a)        Proceeds from the sale of shares of Common Stock pursuant to
Purchase Rights will constitute general funds of the Company. 
 (b)        A
Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, shares of Common Stock subject to Purchase Rights unless and until the Participant’s shares of Common Stock acquired upon exercise of
Purchase Rights are recorded in the books of the Company (or its transfer agent). 

(c)        The Plan and Offering do not constitute an employment contract.
Nothing in the Plan or in the Offering will in any way alter the at will nature of a Participant’s employment, if applicable, or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue in the employ
of the Company or a Related Corporation, or on the part of the Company or a Related Corporation to continue the employment of a Participant. 

(d)        The provisions of the Plan will be governed by the laws of the State
of Delaware without resort to that state’s conflicts of laws rules. 

(e)        If any particular provision of the Plan is found to be invalid or
otherwise unenforceable, such provision will not affect the other provisions of the Plan, but the Plan will be construed in all respects as if such invalid provision were omitted. 

(f)        If any provision of the Plan does not comply with Applicable Law,
such provision shall be construed in such a manner as to comply with Applicable Law.
