Exhibit 10.11


 


Archer
Aviation Inc.


 


2021
Employee Stock Purchase Plan


 


Adopted
by the Board of Directors: August 11, 2021


Approved
by the Stockholders: September 14, 2021


 


1.            General;
Purpose.


 


(a)            The
Plan provides a means by which Eligible Employees of the Company and certain Designated Companies 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 Eligible 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 will be eligible to participate in the Plan as Designated 423 Corporations,
(B) which Related Corporations or Affiliates will be eligible to participate in the Plan as Designated Non-423 Corporations, and
(C) which Designated Companies will participate in each separate Offering (to the extent that the Company makes separate Offerings).


 


(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.


 


(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 Designated Non-423 Corporation, 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 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. Further, to the extent
not prohibited by Applicable Law, the Board or Committee may, from time to time, delegate some or all of its authority under the Plan
to one or more officers of the Company or other persons or groups of persons as it deems necessary, appropriate or advisable under conditions
or limitations that it may set at or after the time of the delegation. 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 4,969,059 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 ten years commencing on January 1, 2022 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) 9,938,118 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 any remaining portion of such maximum number of shares may be used to satisfy purchases of Common Stock under the Non-423 Component.


 






    2 


     


    

 


(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 or a third party designated by the Company (each, a “Company Designee”): (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 or an Affiliate. 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 or an Affiliate, 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 Applicable 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, the Related Corporation, or the Affiliate 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 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.


 






    3 


     


    

 


(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 under the 423 Component 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 under the 423 Component 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 Company, 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 Applicable 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.


 






    4 


     


    

 


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 purchasable either with a percentage or with a maximum dollar amount, as designated by the
Board (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 specified by Board prior to the commencement of
an Offering and will not be 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 or a Company Designee, within the time specified for the Offering, an enrollment form provided by the Company
or Company Designee. 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 and to extent
permitted by Section 423 of the Code with respect to the 423 Component, in addition to or instead of making Contributions by payroll
deductions, a Participant may make Contributions through payment by cash, check or wire transfer prior to a Purchase Date.


 






    5 


     


    

 


(b)            During
an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company or a Company Designee
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 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 Applicable 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 Designated Company or between Designated Companies 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).


 






    6 


     


    

 


(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, subject to Section 423 of the Code with respect to the 423 Component, 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 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, agency or other Governmental Body 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 is not practical or 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.


 






    7 


     


    

 


(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 whole share) within ten business days (or such other period specified by the Board) 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 facilitate compliance 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.


 






    8 


     


    

 


(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 satisfied in whole or in part by (i) 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. The Company shall not be required to issue any shares of
Common Stock under the Plan until such obligations are satisfied.


 


(c)            The
423 Component is exempt from the application of Section 409A of the Code, and any ambiguities herein shall be interpreted to so be
exempt from Section 409A of the Code. The Non-423 Component is intended to be exempt from the application of Section 409A of
the Code under the short-term deferral exception and any ambiguities shall be construed and interpreted in accordance with such intent.
In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Committee determines that an option
granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an option under the
Plan to be subject to Section 409A, the Committee may amend the terms of the Plan and/or of an outstanding option granted under the
Plan, or take such other action the Committee determines is necessary or appropriate, in each case, without the participant’s consent,
