 Exhibit 10.3 

HARMONY BIOSCIENCES HOLDINGS, INC. 

AMENDED AND RESTATED EQUITY INCENTIVE PLAN 

The Board of Directors (the “Board”) of Harmony Biosciences Holdings, Inc. (the “Company”) has adopted this
Amended and Restated Equity Incentive Plan (as amended, the “Plan”) as of August [10], 2020 (the “Effective Date”) to promote the financial interests of the Company by providing a means by which current and
prospective directors, officers, employees, consultants and advisors of the Company and its Affiliates can acquire an equity interest in the Company or be paid incentive compensation measured by the value of the Company’s Common Stock. In
addition to the capitalized terms defined elsewhere in this Plan, defined terms shall have the meanings ascribed to them in Section 9. 

1.    Term. The Plan shall continue in effect from the Effective Date through and including the tenth
(10th) anniversary the Effective Date, unless the Board terminates the Plan prior to such date . Notwithstanding the generality of the foregoing, the Plan shall terminate automatically upon the
effectiveness of the Company’s 2020 Incentive Award Plan. No Awards may be granted under the Plan after the termination or expiration of the Plan. However, any Awards that, by their terms, remain outstanding as of the termination or expiration
of the Plan shall remain outstanding and in full force and effect, and the terms and conditions of the Plan shall survive its termination or expiration and continue to apply to any such Awards. 

2. Administration. 

(a)    The Committee shall administer the Plan. Unless otherwise expressly provided in the Company’s organizational
documents, the acts of a majority of the members present at any meeting of the Committee at which a quorum is present, or acts approved in writing by all of the members of the Committee, shall be deemed the acts of the Committee. 

(b)    Subject to the provisions of the Plan and applicable law, the Committee shall have the sole and plenary authority,
in addition to other express powers and authorizations conferred on the Committee by the Plan, to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to Participants; (iii) determine the number of
shares of Common Stock to be covered by, or with respect to which payments, rights or other matters are to be calculated in connection with, Awards; (iv) determine the terms and conditions of any Award; (v) grant fully-vested Awards;
(vi) determine whether, to what extent and under what circumstances Awards may be settled or exercised in cash, shares of Common Stock, other securities, other Awards or other property; (vii) interpret, administer, reconcile any
inconsistency in, correct any defect in and/or supply any omission in the Plan and any instrument or agreement relating to, or Award granted under, the Plan; (viii) establish, amend, suspend or waive any rules and regulations and appoint such
agents as the Committee shall deem appropriate for the proper administration of the Plan; (ix) accelerate the vesting or exercisability of, payment for or lapse of restrictions on, Awards; and (x) make any other determination and take any
other action that the Committee deems necessary or desirable for the administration of the Plan. 
 (c)    The Committee
may delegate to one or more officers of the Company, or of any Affiliate, the authority to act on behalf of the Committee with respect to any matter, right, obligation or election that is the responsibility of, or that is allocated to, the Committee
in the Plan and that may be so delegated as a matter of law. 
 (d)    Unless otherwise expressly provided in the Plan,
all designations, determinations, interpretations and other decisions under or with respect to the Plan or any Award or any documents evidencing Awards granted pursuant to the Plan shall be made in the sole discretion of the Committee, may

 
be made at any time and shall be final, conclusive and binding upon all Persons, including the Company, any Affiliate, any Participant, any holder or beneficiary of any Award and any member or
stockholder of the Company. 
 (e)    Notwithstanding anything to the contrary contained in the Plan, the Board may, in
its sole discretion, at any time, grant Awards and administer the Plan with respect to such Awards. In any such case, the Board shall have all the authority granted to the Committee under the Plan. 

3.    Shares Subject to the Plan; Grant of Awards; Limitations.  

(a) Subject to adjustment pursuant to Section 6, (i) the aggregate number of shares of Common Stock for which Awards may be delivered
under the Plan shall not exceed 4,320,876 shares of Common Stock, and (ii) the Committee shall not authorize or make grants of (x) Options or SARs under the Plan in respect of more than 1,623,006 shares of Common Stock to any single
Participant during any calendar year, or (y) Incentive Stock Options under the Plan in respect of more than 432,087 shares of Common Stock. 

(b)    The Committee may grant Awards to any Eligible Person. An Eligible Person may be granted more than one Award under
the Plan, and Awards may be granted at any time or times prior to the termination or expiration of the Plan. 

(c)    The number of shares of Common Stock that are available for Awards under the Plan will include any shares of Common
Stock: (i) tendered to the Company by a Participant in payment of any Exercise Price or tax obligations, and (ii) relating to any Awards under the Plan that have been forfeited, cancelled, redeemed, repurchased, expired unexercised or
settled in cash. 
 (d)    Shares of Common Stock delivered by the Company in settlement of Awards may be issued by the
Company from (i) authorized and unissued shares, (ii) shares held in treasury by the Company, (iii) shares purchased by the Company on the open market or by private purchase, or (iv) any combination of the foregoing. 

(e)    Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution
for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines (“Substitute Awards”). If the Committee determines that Substitute Awards are to be granted under the Plan, the
number of shares of Common Stock underlying any Substitute Awards shall not be counted against the aggregate number of shares of Common Stock available for Awards under the Plan. 

4.    Awards.  

(a)    Options. 

(i)    Generally. Each Option granted under the Plan shall be subject to the conditions set forth in this
Section 4(a), and to such other conditions as may be reflected in the applicable Award agreement or the Plan. All Options granted under the Plan shall be Nonqualified Stock Options unless the applicable Award agreement expressly states that the
Option is intended to be an Incentive Stock Option. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the stockholders of the Company in a manner intended to comply with the stockholder approval
requirements of Section 422(b)(1) of the Code. In the case of an Incentive Stock Option, the terms and conditions of such Award shall be subject to, and comply with such rules as may be prescribed under, Section 422 of the Code. If, for
any reason, all or any portion of an Option intended to be an Incentive Stock Option does not qualify as an Incentive Stock Option, then, to the extent of such disqualification, such Option shall be regarded as a Nonqualified Stock Option granted
under the Plan. 

  
 2 

 (ii)    Exercise Price. Except as otherwise provided by
the Committee in the case of Substitute Awards, the exercise price (the “Exercise Price”) per share of Common Stock to be issued pursuant to an Option shall not be less than 100% of the Fair Market Value of a share of Common Stock
as of the Date of Grant; provided, however, that, in the case of an Incentive Stock Option granted to an employee who, at the time of the grant of such Option, owns shares representing more than 10% of the voting power of all
classes of shares of the Company or any Affiliate, the Exercise Price per share shall not be less than 110% of the Fair Market Value of a share of Common Stock as of the Date of Grant. 

(iii)    Vesting and Expiration. Options granted under the Plan shall (A) vest and become exercisable
in such manner and on such date or dates, and (B) expire after such period, not to exceed ten years from the Date of Grant (the “Option Period”), as set forth in an Award agreement; provided, however, that
the Option Period shall not exceed five years from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns shares representing more than 10% of the voting power of all classes of shares of
the Company or any Affiliate. Notwithstanding any vesting dates set forth in an Award agreement, the Committee may, in its sole discretion, accelerate the vesting and/or exercisability of any Option, which acceleration shall not affect the terms and
conditions of such Option other than with respect to vesting and/or exercisability. Unless otherwise provided in an Award agreement, the unvested portion of an Option shall expire upon termination of employment or service of the Participant to whom
the Option was granted. Unless otherwise provided in an Award agreement, the vested portion of such Option shall be subject to the following terms: 

(1)    if such Participant’s employment or service is terminated by reason of such Participant’s death or
Disability, then, subject to the terms of Section 6, the portion of such Option that was vested as of the effective date of termination shall remain exercisable until the earlier of (x) the first anniversary of the effective date of
termination, and (y) the expiration of the Option Period, 
 (2)    if such Participant’s employment or
service is terminated by the Company without Cause, and such Participant has delivered to the Company a general release of claims against the Company, in form and substance acceptable to the Committee, and such release has become irrevocable, then,
subject to the terms of Section 6, the portion of such Option that was vested as of the effective date of termination shall remain exercisable until the earlier of (x) ninety (90) days following the effective date of termination, and
(y) the expiration of the Option Period, and 
 (3)    if such Participant’s employment or service is
terminated for any reason other than as set forth above, including by the Company for Cause or by such Participant for any reason (other than death or Disability), then the portion of such Option that was vested as of the effective date of
termination shall automatically expire upon the effective date of termination. 
 (iv)    Method of Exercise and
Form of Payment. Options that have become exercisable may be exercised by delivery of written notice of exercise to the Company in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall
be payable (A) in cash, promissory notes (to the extent permitted by the Committee and applicable law) and/or shares of Common Stock having a value on the date of exercise equal to the Exercise Price (including pursuant to procedures approved
by the Committee, by means of attestation of ownership of a sufficient number of shares of Common Stock in lieu of actual delivery of such shares to the Company), provided, that such shares of Common Stock are not subject to any pledge
or other security interest, (B) by a “net exercise” method whereby the Company withholds from the delivery of the shares of Common Stock for which the Option was exercised (or in the case of a public market, uses a broker-assisted
cashless exercise of) that 

  
 3 

 
number of shares of Common Stock having a value equal to the aggregate Exercise Price for the shares of Common Stock for which the Option was exercised, or (C) by such other method as the
Committee may permit in accordance with applicable law. Any fractional shares of Common Stock shall be settled in cash. 

(v)    Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded
an Incentive Stock Option under the Plan shall notify the Company in writing immediately after the date the Participant makes a disqualifying disposition of any shares of Common Stock acquired pursuant to the exercise of such Incentive Stock Option.
A disqualifying disposition is any disposition (including any sale) of such shares of Common Stock before the later of (A) two years after the Date of Grant of the Incentive Stock Option or (B) one year after the date of exercise of the
Incentive Stock Option. The Company may, if determined by the Committee and in accordance with procedures established by the Committee, retain possession of any shares of Common Stock acquired pursuant to the exercise of an Incentive Stock Option as
agent for the applicable Participant until the end of the period described in the preceding sentence. 
 (b)    Stock
Appreciation Rights. 
 (i)    Generally. Each SAR granted under the Plan shall be subject to the
conditions set forth in this Section 4(b), and to such other conditions as may be reflected in the applicable Award agreement. 

(ii)    Strike Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the
strike price (the “Strike Price”) per share of Common Stock for each SAR shall not be less than the Fair Market Value of a share of Common Stock as of the Date of Grant; provided that, in the case of a SAR granted in tandem with an
Option, the Strike Price shall not be less than the Exercise Price of the related Option. 
 (iii)    Vesting and
Expiration. A SAR granted in tandem with an Option shall become exercisable and shall expire according to the same vesting schedule and expiration provisions as the corresponding Option. A SAR shall (A) vest and become exercisable in
such manner and on such date or dates, and (B) expire after such period, not to exceed ten years from the Date of Grant (the “SAR Period”), in each case, as set forth in an Award agreement. Notwithstanding any vesting dates set
by the Committee in the Award agreement, the Committee may, in its sole discretion, accelerate the vesting and/or exercisability of any SAR, which acceleration shall not affect the terms and conditions of such SAR other than with respect to vesting
and/or exercisability. Unless otherwise provided in an Award agreement, the unvested portion of a SAR shall expire upon termination of employment or service of the Participant to whom the SAR was granted. Unless otherwise provided in an Award
agreement, the vested portion of such SAR shall be subject to the following terms: 
 (1)    if such Participant’s
employment or service is terminated by reason of such Participant’s death or Disability, then, subject to the terms of Section 6, the portion of such SAR that was vested as of the effective date of termination shall remain exercisable
until the earlier of (x) the first anniversary of the effective date of termination, and (y) the expiration of the SAR Period, 

(2)    if such Participant’s employment or service is terminated by the Company without Cause, and such Participant
has delivered to the Company a general release of claims against the Company, in form and substance acceptable to the Committee, and such release has become irrevocable, then, subject to the terms of Section 6, the portion of such SAR that was
vested as of the effective date of termination shall remain exercisable until the earlier of (x) ninety (90) days following the effective date of termination, and (y) the expiration of the SAR Period, and 

  
 4 

 (3)    if such Participant’s employment or service is terminated
for any reason other than as set forth above, including by the Company for Cause or by such Participant for any reason (other than death or Disability), then the portion of such SAR that was vested as of the effective date of termination shall
automatically expire upon the effective date of termination. 
 (iv)    Method of Exercise and Form of
Payment. SARs that have become exercisable may be exercised by delivery of written notice of exercise to the Company in accordance with the terms of the Award, specifying the number of shares subject to the SARs to be exercised. Upon the
exercise of any SARs, the Company shall pay to the Participant an amount equal to the number of shares subject to the SARs that are being exercised multiplied by the excess, if any, of the Fair Market Value of a share of Common Stock on the exercise
date over the Strike Price, less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. Unless otherwise provided in an Award agreement, the Company may
pay such amount in cash, in shares of Common Stock with a value equal to such amount, or any combination thereof, as determined by the Committee. Any fractional shares of Common Stock shall be settled in cash. 

(c)    Restricted Stock and Restricted Stock Units. 

(i)    Generally. Each grant of Restricted Stock or Restricted Stock Units under the Plan shall be subject
to the conditions set forth in this Section 4(c) and to such other conditions as may be reflected in the applicable Award agreement. 

(ii)    Restricted Stock – Accounts, Escrow or Similar Arrangement. Upon the grant of Restricted
Stock, a book entry in a restricted account shall be established in the Participant’s name at the Company’s transfer agent and, if the Committee determines that the Restricted Stock shall be held by the Company or in escrow rather than
held in such restricted account pending the release of the applicable restrictions, the Committee may require the Participant to execute and deliver to the Company (A) an escrow agreement satisfactory to the Committee, if applicable, and
(B) an appropriate stock power (endorsed in blank) satisfactory to the Committee with respect to the Restricted Stock covered by such agreement. If a Participant shall fail to execute an agreement evidencing an Award of Restricted Stock and, if
applicable, an escrow agreement and blank stock power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 4(c), and unless otherwise set forth in an
applicable Award agreement, the Participant generally shall have the rights and privileges of a stockholder as to such Restricted Stock, including the right to vote such Restricted Stock (to the extent such Restricted Stock conveys the right to
vote) and the right to receive dividends, if applicable. To the extent shares of Restricted Stock are forfeited, all rights of the Participant to such shares and as a stockholder with respect thereto (and any withheld and accumulated dividends
thereon) shall terminate automatically, without further obligation on the part of the Company, and the Participant shall return to the Company promptly any stock certificates issued to the Participant evidencing such shares. 

(iii)    Vesting; Acceleration of Lapse of Restrictions. The Restricted Period shall lapse with respect to
an Award of Restricted Stock or Restricted Stock Units at such times as provided in an Award agreement, and the unvested portion of any Award of Restricted Stock and Restricted Stock Units shall terminate and be forfeited automatically upon
termination of employment or service of the Participant. 
 (iv)    Delivery of Restricted Stock; Settlement of
Restricted Stock Units. 
 (1)    Upon the expiration of the Restricted Period with respect to any shares of
Restricted Stock, the restrictions set forth in the applicable Award agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award agreement. If an escrow arrangement is used, upon such
expiration, the Company shall deliver to the Participant, or his or 

  
 5 

 
her beneficiary, without charge, one or more stock certificates evidencing the shares of Restricted Stock that have not then been forfeited and with respect to which the Restricted Period has
expired (rounded down to the nearest full share). Dividends, if any, that may have been withheld by the Company and attributable to any particular share of Restricted Stock shall be distributed to the Participant in cash or, at the sole discretion
of the Committee, in shares of Common Stock having a Fair Market Value as of the date on which the Restricted Period expired equal to the amount of such dividends, upon the release of restrictions on such share and, if any such shares of Restricted
Stock are forfeited, the Participant shall have no right to such dividends (except as otherwise set forth in the applicable Award agreement). 

(2)    Unless otherwise provided in an Award agreement, upon the expiration of the Restricted Period with respect to any
outstanding Restricted Stock Units, the Company shall deliver to the Participant, or his or her beneficiary, without charge, one share of Common Stock for each such outstanding Restricted Stock Unit; provided, however, that the Company
may, as determined by the Committee, in its sole discretion, (x) pay cash, or part cash and part shares of Common Stock, in lieu of delivering only shares of Common Stock in respect of such Restricted Stock Units or (y) defer the delivery
of shares of Common Stock (or cash, or part shares of Common Stock and part cash, as the case may be) beyond the expiration of the Restricted Period, if such delivery would result in a violation of applicable law, until such time as such payment or
delivery would no longer result in a violation of applicable law. If, in settling any Restricted Stock Units, a cash payment is made in lieu of delivering any shares of Common Stock, the amount of such cash payment shall be equal to the Fair Market
Value of the corresponding shares of Common Stock as of the date on which the Restricted Period expired. The Committee may grant dividend equivalents in respect of Restricted Stock Units awarded on such terms and conditions as the Committee
determines. 
 (v)    Legends on Restricted Stock. As determined by the Committee, in its sole
discretion, each certificate representing shares of Restricted Stock awarded under the Plan shall bear a legend in the form and containing such information as the Committee determines appropriate until the lapse of all restrictions with respect to
such shares of Restricted Stock. 
 (d)    Stock Bonus Awards. The Committee may issue unrestricted shares of
Common Stock, or other Awards denominated in shares of Common Stock, under the Plan to Eligible Persons, either alone or in tandem with other Awards, in such amounts as the Committee shall determine, in its sole discretion (each, a “Stock
Bonus Award”). Each Stock Bonus Award granted under the Plan shall be subject to such conditions as may be reflected in the applicable Award agreement. 

5.    [Reserved.] 

6.    Changes in Capital Structure and Similar Events.  

(a)    Effect of Certain Events. In the event of (i) any extraordinary dividend or other extraordinary
distribution (whether in the form of cash, shares of Common Stock, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, amalgamation, consolidation,
split-up, split-off, combination, repurchase or exchange of shares of Common Stock or other securities of the Company, issuance of warrants or other rights to acquire
shares of Common Stock or other securities of the Company, or other similar corporate transaction or event (including a Change in Control) that affects the shares of Common Stock, or (ii) unusual or nonrecurring events (including a Change in
Control) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or changes in applicable rules, rulings, regulations or other requirements of any governmental body or securities exchange or inter-dealer
quotation system, accounting principles or law, such that in either case an adjustment is determined by the Committee, in its sole discretion, to be necessary or appropriate, then 

  
 6 

 
the Committee shall make any such adjustments in such manner as it may deem equitable, including any or all of the following: 

(i)    adjusting any or all of (A) the number of shares of Common Stock or other securities of the Company (or
number and kind of other securities or other property) that may be delivered in respect of Awards or with respect to which Awards may be granted under the Plan (including adjusting any or all of the limitations under Section 3 of the Plan) and
(B) the terms of any outstanding Award, including (1) the number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding
Awards relate, or (2) the Exercise Price or Strike Price with respect to any Award; 
 (ii)    providing for a
substitution or assumption of Awards, accelerating the exercisability of, lapse of restrictions on, or termination of, Awards or providing for a period of time for exercise prior to the occurrence of such event; and 

(iii)    canceling any one or more outstanding Awards or portion thereof and causing to be paid to the holders thereof,
in cash, shares of Common Stock, other securities or other property, or any combination thereof, the value of such Awards, if any, as determined by the Committee (which if applicable may be based upon the price per share of Common Stock received or
to be received by other stockholders of the Company in such event), including, in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee)
of the shares of Common Stock subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR, respectively (it being understood that, in such event, any Option or SAR having a per share Exercise Price or Strike
Price equal to, or in excess of, the Fair Market Value of a share of Common Stock subject thereto may be canceled and terminated without any payment or consideration therefor); provided, however, that in the case of any “equity
restructuring” (within the meaning of FASB Accounting Standards Codification Topic 718) or any successor rule, the Committee shall make an equitable or proportionate adjustment to outstanding Awards to reflect such equity restructuring. Any
adjustment in Incentive Stock Options under this Section 6(a) (other than any cancellation of Incentive Stock Options) shall be made only to the extent not constituting a “modification” within the meaning of Section 424(h)(3) of
the Code, and any adjustments under this Section 6(a) shall be made in a manner that does not adversely affect the exemption under Section 409A or the Exchange Act, to the extent applicable. The Company shall give each Participant notice
of an adjustment hereunder and, upon notice, such adjustment shall be conclusive and binding for all purposes. 

(b)    Effect of Change in Control. The effect, if any, of a Change in Control on any Awards outstanding at the
time immediately prior to such Change in Control will be as specifically set forth in the corresponding Award agreement, or if no such treatment is specified, then such outstanding Awards shall be subject to any agreement of purchase, merger or
reorganization that effects such Change in Control, which agreement shall provide for treatment of such Awards. 

(c)    No Effect on Authority of the Board or Stockholders. The existence of this Plan and any Awards granted
hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business,
any merger or consolidation of the Company, any issue of debt or equity securities ahead of or affecting Common Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or
any part of its assets or business or any other corporate act or proceeding.

 7.    Amendments and Termination.  

(a)    Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue or terminate the
Plan, or any portion thereof, at any time; provided, that (i) no amendment to Section 7(b) (to the extent required by the proviso in such Section 7(b)) shall be made without stockholder approval and (ii) no such
amendment, alteration, suspension, discontinuation or termination shall be made without stockholder approval if such stockholder approval is necessary to comply with any tax or regulatory requirement applicable to the Plan (including as necessary to
comply with any rules or requirements of any securities exchange or inter-dealer quotation system on which the Common Stock may be listed or quoted); provided, further, that (except as provided above with respect to adjustments by the
Committee under Section 6) any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall
not to that extent be effective without the consent of the affected Participant, holder or beneficiary. Notwithstanding the foregoing, the Committee may amend the Plan, without the consent of any Participant to remedy a potential violation of Code
Section 409A. 
 (b)    Amendment of Award Agreements. The Committee may waive any conditions or rights
under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted or the associated Award agreement, prospectively or retroactively; provided that any such waiver, amendment, alteration,
suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected
Participant; provided, further, that, without stockholder approval as may be required by applicable law or the rules of the applicable securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted,
except as otherwise permitted under Section 6, (i) no amendment or modification may reduce the Exercise Price of any Option or the Strike Price of any SAR, (ii) the Committee may not cancel any outstanding Option or SAR and replace it with
a new Option or SAR, another Award or cash and (iii) the Committee may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer
quotation system on which the Common Stock is listed or quoted. No such approval will be required for the items in this Section 7(b)(i) through and including (iii) if stockholder approval is not required by applicable law or such rules.

 8.    Repurchase. 

(a)    Applicability. Except as set forth in an applicable award Agreement, in addition to any terms or conditions
provided in any stockholders agreement to which any shares of Common Stock held by a Participant are then subject, any shares of Common Stock held by a Participant (or any subsequent holder of Common Stock granted or issued to such Participant)
pursuant to this Plan shall be subject to the repurchase provisions of this Section 8 by the Company (or an designee of the Company). Upon (i) the later of (A) the Participant’s termination of employment or engagement with
Company or any of its Affiliates or (B) receipt by the Participant, or Participant’s estate, of underlying Common Stock with respect to an Award or (ii)(A) becoming party to divorce proceedings or (B) Participant’s personal
bankruptcy proceedings (each event in (i) or (ii), a “Triggering Event”), all of the shares of Common Stock then held by the Participant (or a Permitted Transferee) shall be subject to repurchase by the Company pursuant to this
Section 8 (the “Repurchase Right”). Without limiting the foregoing, in connection with such Participant becoming party to a divorce proceeding or bankruptcy proceeding (a “Proceeding”), the Committee shall have
the right to modify the Award to be exercised or settled for cash instead of shares of Common Stock, upon notice to such Participant. 

(b)    Repurchase Price. The purchase price (“Repurchase Price”) for each share of Common Stock
being repurchased pursuant to this Section 8 shall be equal to the Fair Market Value of a share of Common Stock as of the date of the Triggering Event, except in the case of a termination of Participant’s employment or engagement with the
Company or any of its Affiliates for Cause, in which 

  
 8 

 
case the Repurchase Price will be the lesser of the Fair Market Value of, or the Participant’s cash outlay paid (less any distributions received) for, such shares of Common Stock. In respect
of any Triggering Event that is not a Proceeding, the Repurchase Price for each restricted share of Common Stock or otherwise unvested share of Restricted Stock being repurchased shall be the lesser of: (i) the amount paid in cash by the
Participant for such share of Common Stock (less any distributions made prior to such repurchase in respect of such restricted shares) and (ii) the Fair Market Value of such shares. For the avoidance of doubt, if no purchase price is or was
paid in cash for an unvested share of Restricted Stock, then upon the Participant’s termination of employment or engagement, such shares of Restricted Stock or otherwise unvested shares of Common Stock under an Award shall be automatically
forfeited to the Company without consideration. 
 (c)    Repurchase Notice. The Company (or its designee) may
(but shall not be obligated to) elect to purchase all or any portion of the Participant’s shares of Common Stock received in respect of Awards under the Plan on the terms contained in this Section 8 by delivering written notice (the
“Repurchase Notice”) to the Participant (or the applicable subsequent holder) within ninety (90) days after the Triggering Event. The Repurchase Notice shall set forth the number of shares of Common Stock to be acquired from
the Participant (or Permitted Transferee), the aggregate consideration to be paid for such Common Stock, and the time and place for the closing of such purchase (the “Closing”). 

(d)    Repurchase Closing. At the Closing (which, except as provided in this Section 8, shall not occur more
than thirty (30) days following delivery of the Repurchase Notice), the Participant (or Permitted Transferee) shall deliver to the Company such documentation as the Company may reasonably require to effect the conveyance to the Company of all
of the shares of Common Stock being repurchased, free and clear of all claims, liens or encumbrances. The Company and its Affiliates shall be entitled to offset from amounts payable to the Participant hereunder an amount equal to all (or a portion)
of any amounts then owed by the Participant to the Company or any of its Affiliates (so long as such amounts offset are not in violation of Code Section 409A). The Company shall be entitled to receive customary representations and warranties as
to ownership, title, authority to sell and the like from the Participant (or the applicable subsequent holder) regarding such sale, to require the Participant’s (or the applicable subsequent holder’s) signature to be guaranteed and to
receive such other evidence, including applicable inheritance and estate tax waivers, as may reasonably be necessary to effect the purchase of the shares of Common Stock. The Company may, at its election, pay the Repurchase Price by delivering a
promissory note, payable in four equal annual installments, with the first installment of the Repurchase Price to be paid on the first anniversary of the Closing, and subsequent annual installments to be due and payable on the successive anniversary
dates of the Closing. Interest shall accrue from the date of the Closing on the balance of the Repurchase Price remaining unpaid from time to time at the prime rate published in The Wall Street Journal on the date of Closing, and accrued interest
shall be payable together with each annual installment of the Repurchase Price. All or part of the Repurchase Price may be prepaid without penalty or premium. Notwithstanding the foregoing, all amounts due shall become immediately due and payable on
the tenth (10th) day following a Change in Control. The Company shall be permitted to apply the proceeds of the repurchase of any Common Stock hereunder towards the repayment of any loan or other obligation owed by a Participant to the Company or
its Affiliates, including any loan the Participant received in connection with the purchase of the Common Stock under any Award. 

(e)    Failure to Transfer Shares. If the Participant (or Permitted Transferee) fails, for any reason, to tender
any documentation representing the Common Stock to be repurchased hereunder or otherwise fails to comply with this Section 8, the Company may, at its option, in addition to all other remedies it may have, deliver to the Participant (or
Permitted Transferee) the purchase price for such Common Stock as is herein specified (which may include a promissory note). The Company then shall cancel on its books the documentation representing the Common Stock to be repurchased and all of the
Participant’s (or the applicable subsequent holder’s) rights in and to such Common Stock shall terminate 

  
 9 

 
without the need for further action of the Participant. If the Company (or its designee) does not repurchase all of the Participant’s (or the applicable subsequent holder’s) Common
Stock as provided in this Section 8, the Company will modify its documentation to accurately represent the Participant’s (or Permitted Transferee’s) continued ownership of the Common Stock that the Company (or its designee) did not
repurchase. 
 (f)    Tolling. Notwithstanding anything to the contrary in an Award agreement or herein,
the Company may toll the Closing if it determines that (i) the purchase of such Common Stock (whether or not together with any other purchases of shares of Common Stock), would result (A) in a violation of any applicable law or
(B) after giving effect thereto, in a violation of any then-existing credit or similar agreements of the Company or its Affiliates, (ii) there exists a violation of a credit or other agreement binding upon any the Company or its Affiliates
which could reasonably be expected to prohibit such issuance or purchase, (iii) the Company does not have funds available and appropriate to effect such purchase, or (iv) the consent of any legal, judicial, regulatory, or other
governmental entity is required to consummate such redemption or repurchase. The Company shall, upon making any such determination, notify the Participant that it will not purchase such Common Stock at such time as specified in the Repurchase Notice
and has deferred its right to make such purchase until such (x) consent is obtained or (y) violation of applicable law or credit agreement or unavailability of funds would not, as applicable, result therefrom or has ceased. 

(g)    Cooperation. In the event that Common Stock is to be repurchased pursuant to this Section 8, as
a condition to receipt of any Award, the Participant will take all steps necessary and desirable to obtain all required third-party, governmental and regulatory consents and approvals and take all other actions necessary and desirable to facilitate
consummation of such repurchase(s) in a timely manner. 
 9.    Definitions. In
addition to the capitalized terms defined throughout the Plan, except as otherwise defined in an Award agreement or an overriding written agreement between the Company and a Participant, the following capitalized terms shall have the corresponding
meanings set forth in this Section 9: 
 (a) “Affiliate” means any parent or direct or indirect subsidiary of
the Company; provided, that, with respect to Incentive Stock Options, the term shall only mean “parent corporation” and “subsidiary corporation” as defined in Sections 424(e) and 424(f) of the Code;
further, provided, that, with respect to the award of any “stock right” within the meaning of Section 409A of the Code, such affiliate must qualify as a “service recipient” within the meaning of
Section 409A of the Code and in applying Section 1563(a)(1), (2) and (3) of the Code for purposes of determining a controlled group of corporations under Section 414(b) of the Code and in applying Treasury Regulation Section 1.414(c)-2 for purposes of determining trades or businesses (whether or not incorporated) that are under common control for purposes of Section 414(c) of the Code, the language “at least 50
percent” is used instead of “at least 80 percent.” 
 (b)    “Award” means
any SAR, Incentive Stock Option, Nonqualified Stock Option, Restricted Stock, Restricted Stock Unit or Stock Bonus Award granted under the Plan. 

(c)    “Cause” means, in the case of a particular Award, unless the applicable Award agreement
states otherwise, (i) the Company or an Affiliate having “cause” to terminate a Participant’s employment or service, as defined in any employment or consulting agreement or similar services agreement between the Participant and
the Company or an Affiliate in effect at the time of such termination or (ii) in the absence of any such employment, consulting, or similar services agreement (or the absence of any definition of “Cause” contained therein), the
Participant’s (A) material breach of his or her obligations under any agreement or arrangement entered into with the Company or its Affiliates (which remains uncured (to the extent the Committee reasonably determines curable) for at least
ten (10) days following 

  
 10 

 
notice of such breach); (B) gross negligence or willful misconduct in the performance of or non-performance of his or her duties to the Company or its
Affiliates; (C) breach of any of the Company’s or its Affiliates’ written policies or procedures in each case in any respect which causes or is reasonably expected to cause harm to the Company or any Affiliate; (D) commission of
a felony or a crime of moral turpitude (or the procedural equivalent of the foregoing); (E) commission of an act involving deceit, fraud, perjury or embezzlement involving the Company or its Affiliates or any client, customer, supplier or business
relationship of the Company or any Affiliate; (F) repeatedly being under the influence of drugs or alcohol (other than over-the-counter or prescription medicine or
other medically-related drugs to the extent they are taken in accordance with their directions or under the supervision of a physician) which inhibits the performance of such Participant’s duties to the Company or its Affiliates, or, while
under the influence of such drugs or alcohol, engaging in inappropriate conduct during the performance of his or her duties to the Company or its Affiliates; or (G) failure to follow lawful directives of the Participant’s supervisor, which
(which failure remains uncured (to the extent the Committee reasonably determines curable) for at least ten (10) days following initial notice of such failure). Any rights to cure that are expressly described in this definition will only be
afforded for the initial occurrence of any purported grounds of Cause and the Participant will not have any right (unless the Committee otherwise determines) to cure such purported grounds. Any determination of whether Cause exists shall be made by
the Committee in its sole discretion. 
 (d)    “Change in Control,” in the case of a particular
Award, unless the applicable Award agreement states otherwise or contains a different definition of “Change in Control,” means (i) the sale, lease, transfer, conveyance or other disposition, in one transaction or a series of related
transactions, of all or substantially all of the assets of the Company, (ii) the sale, transfer, conveyance or other disposition, in one transaction or a series of related transactions, of the outstanding equity securities of the Company, and
(iii) the merger or consolidation of the Company with another Person, in each case in clauses (ii) and (iii) above under circumstances in which the holders of the voting power of outstanding equity securities of the Company, immediately
prior to such transaction, are no longer, in the aggregate, the beneficial owners (within the meaning of Rule 13d-3 of the Exchange Act), directly or indirectly through one or more intermediaries, of more than
fifty percent (50%) of the voting power of the outstanding equity securities of the surviving or resulting corporation or acquirer, as the case may be, immediately following such transaction. A sale (or multiple related sales) of one or more
Subsidiaries (whether by way of merger, consolidation, reorganization or sale of all or substantially all of the assets or securities) which constitutes all or substantially all of the consolidated assets of the Company shall be deemed a Change in
Control. In addition, notwithstanding anything herein to the contrary, in any circumstance in which the definition of “Change in Control” under this Plan would otherwise be operative and with respect to which the additional tax under
Section 409A of the Code would apply or be imposed, but where such tax would not apply or be imposed if the meaning of the term “Change in Control” met the requirements of Section 409A(a)(2)(A)(v) of the Code, then the term
“Change in Control” herein shall mean, but only for the transaction, event or circumstance so affected and the item of income with respect to which the additional tax under Section 409A of the Code would otherwise be imposed, a
transaction, event or circumstance that is both (x) described in the preceding provisions of this definition, and (y) a “change in control event” within the meaning of Treasury Regulations
Section 1.409A-3(i)(5). Notwithstanding the foregoing, in the case of a particular Award, unless the applicable Award agreement states otherwise or contains a different definition of “Change in
Control,” the sale or transfer of equity securities in a Public Offering shall not be considered in determining whether a transaction constitutes a Change in Control. 

(e)    “Code” means the Internal Revenue Code of 1986, as amended, and any successor thereto.
Reference in the Plan to any section of the Code shall be deemed to include any regulations or other interpretative guidance under such section, and any amendments or successor provisions to such section, regulations or guidance. 

  
 11 

 (f)    “Committee” means the Compensation
Committee, as constituted from time to time, of the Board, or if no such committee shall be in existence at any relevant time, the term “Committee” for purposes of the Plan shall mean the Board.

other securities into which such shares of common stock may be converted or into which they may be exchanged). 

(h)    “Date of Grant” means the date on which the granting of an Award is authorized, or such
other date as may be specified in such authorization; provided, however, that such date complies with the requirements of Sections 422 and 409A of the Code, as applicable. 

(i)    “Disability” means (except as expressly provided in the Participant’s Award agreement,
or in the case of Incentive Stock Options, in which case, Disability shall have the definition attributed to a permanent disability in Section 22(e)(3) of the Code), the Participant’s inability to perform the essential functions of such
Participant’s service due to a medically determinable physical or mental impairment, which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than twelve months; provided,
however, that a Participant shall be deemed to have a Disability if he or she is determined to be totally disabled by the U.S. Social Security Administration. 

(j)    “Eligible Person” means any (i) employee of the Company or any Affiliate;
(ii) director of the Company or any Affiliate; (iii) consultant or advisor to the Company or any Affiliate; or (iv) prospective employee, director, officer, consultant or advisor who has accepted an offer of employment, engagement or
consultancy from the Company or any Affiliate, and who would satisfy the provisions of clauses (i) through (iii) above once he or she begins employment with or begins providing services to the Company or any Affiliate. 

(k)    “Exchange Act” means the Securities Exchange Act of 1934, as amended, and any reference in
the Plan to any section of (or rule promulgated under) the Exchange Act shall be deemed to include any rules, regulations or other interpretative guidance under such section or rule, and any amendments or successor provisions to such
section, rules, regulations or guidance. 
 (l)    “Fair Market Value” means, as of any date,
the fair market value of a share of Common Stock, determined as follows: (i) if the Common Stock is listed on any established stock exchange, its Fair Market Value will be the closing sales price for such Common Stock as quoted on such exchange
for such date, or if no sale occurred on such date, the last day preceding such date during which a sale occurred, as reported in The Wall Street Journal or another source the Committee deems reliable or (ii) without an established
market for the Common Stock, the Committee will determine the Fair Market Value in its discretion; provided, that for purposes of setting an Exercise Price or Strike Price, as applicable, Fair Market Value will be determined in accordance with Code
Section 409A and Treasury Regulation Section 1.409A-1(b)(5). 

(m)    “Incentive Stock Option” means an Option that is designated by the Committee as an
incentive stock option as described in Section 422 of the Code and otherwise meets the requirements set forth in the Plan and Section 422 of the Code. 

(n)    “Nonqualified Stock Option” means an Option that is not designated by the Committee as an

 13 

 10.    [Reserved.] 

 11.    General. 

(a)    Award Agreements. Each Award under the Plan shall be evidenced by an Award agreement, which shall be
delivered to the Participant (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)) and shall specify the terms and conditions of the Award
and any rules applicable thereto. 
 (b)    Nontransferability. 

(i)    Each Award shall be exercisable only by a Participant during the Participant’s lifetime, or, if permissible
under applicable law, by the Participant’s legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or by the laws of descent and
distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or an Affiliate; provided that the designation of a beneficiary in
accordance with Section 11(f) shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance. 

(ii)    Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive
Stock Options) to be transferred by a Participant, without consideration, to a Permitted Transferee, subject to such rules as the Committee may adopt consistent with any applicable Award agreement to preserve the purposes of the Plan; provided, that
the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer, and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan. 

(iii)    The terms of any Award transferred in accordance with the immediately preceding sentence shall apply to the
Permitted Transferee, and any reference in the Plan, or in any applicable Award agreement, to a Participant shall be deemed to refer to the Permitted Transferee, except that (A) Permitted Transferees shall not be entitled to transfer any Award,
other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the Common
Stock to be acquired pursuant to the exercise of such Option if the Committee determines, consistent with any applicable Award agreement, that such a registration statement is necessary or appropriate; (C) the Committee or the Company shall not
be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of the termination of the
Participant’s employment by, or services to, the Company or an Affiliate under the terms of the Plan and the applicable Award agreement shall continue to be applied with respect to the Participant, including that an Option shall be exercisable
by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award agreement. 

(c)    Tax Withholding. 

(i)    A Participant shall be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have
the right and is hereby authorized to withhold, from any cash, shares of Common Stock, other securities or other property deliverable under any Award or from any compensation or other amounts owing to a Participant, the amount (in cash, shares of
Common Stock, other securities or other property) of any required withholding taxes in respect of an Award, its exercise, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of
the Committee or the Company to satisfy all obligations for the payment of such withholding taxes. 

  
 14 

 (ii)    Without limiting the generality of clause (i) above, the
Committee may permit a Participant to satisfy, in whole or in part, the foregoing withholding liability by (A) the delivery of shares of Common Stock (which are not subject to any pledge or other security interest) owned by the Participant
having a Fair Market Value equal to such withholding liability or (B) having the Company withhold from the number of shares of Common Stock otherwise issuable or deliverable pursuant to the exercise or settlement of the Award a number of shares
with a Fair Market Value equal to such withholding liability (but no more than the minimum required statutory withholding liability). 

(d)    No Claim to Awards; No Rights to Continued Employment; Waiver. No employee of the Company or an Affiliate,
or other Person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of
Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively
among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Company or an
Affiliate, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Company and any of its Affiliates may at any time dismiss a Participant from employment or discontinue any consulting relationship, free
from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or
vesting of an Award or to damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award agreement, notwithstanding any provision to the
contrary in any written employment contract or other agreement between the Company and its Affiliates and the Participant, whether any such agreement is executed before, on or after the Date of Grant. 

(e)    International Participants. With respect to Participants who reside or work outside of the United States of
America, the Committee may in its sole discretion amend the terms of the Plan or outstanding Awards (or adopt a subplan) with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable
tax or other treatment for a Participant, the Company or its Affiliates. 
 (f)    Designation and Change of
Beneficiary. Each Participant may file with the Committee a written designation of one or more persons as the beneficiary(ies) who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon his or
her death. A Participant may, from time to time, revoke or change his or her beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee
shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant’s death, and in no event shall it be effective as of a
date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be his or her spouse at the time of death or, if the Participant is unmarried at the time of death, his or her estate.
Notwithstanding anything herein to the contrary, to the extent that a Participant’s beneficiary designation would result in a duplication of, or unintended, benefits payable under this Plan or would otherwise violate applicable law, the
Committee shall have the authority to disregard such designation and payments shall be made in accordance with applicable law. 

  
 15 

 (g)    Termination of Employment/Service. Unless determined
otherwise by the Committee at any point following such event or as otherwise provided in an Award agreement, service shall not be considered terminated in the case of (i) any approved leave of absence, (ii) transfers among the Company, any
Affiliate, or any successor, in any capacity of any employee, director or consultant, or (iii) any change in status as long as the individual remains in the service of the Company or an Affiliate in any capacity of employee, director or
consultant. An approved leave of absence shall include sick leave, military leave, or any other authorized personal leave. For purposes of each Incentive Stock Option, if such leave exceeds three (3) months, and
re-employment upon expiration of such leave is not guaranteed by statute or contract, then the Incentive Stock Option shall be treated as a Nonqualified Stock Option on the day following the expiration of such
three (3) month period. 
 (h)    No Rights as a Stockholder. Except as otherwise specifically provided in
the Plan or any Award agreement, no person shall be entitled to the privileges of ownership in respect of shares of Common Stock that are subject to Awards hereunder until such shares have been issued or delivered to that person. The Committee may
require each Participant purchasing or receiving shares of Common Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring Common Stock without a view to the distribution thereof. 

(i)    Government and Other Regulations/Limitations. 

(i)    The Plan is intended to be a “compensatory benefit plan” within the meaning of such term under Rule 701
of the Securities Act. Grants of Awards pursuant to the Plan (and the issuance of shares of Common Stock upon the exercise of any Options) are intended to qualify for an exemption from the registration requirements under the Securities Act pursuant
to Rule 701 and under analogous provisions of applicable state securities laws (collectively, the “Registration Exemptions”). In the event that any provision of the Plan would cause any Award or Option granted pursuant to the Plan
to not qualify for the Registration Exemptions, the Plan will be deemed to be amended automatically to the extent necessary to cause all such Awards and Options to qualify for the Registration Exemptions. 

(ii)    The obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject
to all applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to
sell, and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or
unless the Company has received an opinion of counsel, satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have
been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have the authority to provide that all
certificates for shares of Common Stock or other securities of the Company or any Affiliate delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the
applicable Award agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system upon which such shares or other securities
are then listed or quoted and any other applicable federal, state, local or non-U.S. laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to
such restrictions. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it in its sole discretion deems necessary or advisable
in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject. 

  
 16 

 (iii)    The Committee may toll the exercise or settlement of an Award
or any portion thereof if it reasonably determines that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of shares of Common Stock from the public markets, the
Company’s issuance of shares of Common Stock to the Participant, the Participant’s acquisition of shares of Common Stock from the Company and/or the Participant’s sale of shares of Common Stock to the public markets, illegal,
impracticable or inadvisable. 
 (j)    Payments to Persons Other Than Participants. If the Committee shall find
that any Person to whom any amount is payable under the Plan is unable to care for his affairs because of illness or accident, or is a minor, or has died, then any payment due to such person or his estate (unless a prior claim therefor has been made
by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to his or her spouse, child, relative, an institution maintaining or having custody of such Person, or any other Person deemed by the Committee to be a
proper recipient on behalf of such Person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor. 

(k)    Nonexclusivity of the Plan. Neither the adoption of this Plan by the Board nor the submission of this Plan
to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock
options or other equity-based awards otherwise than under this Plan, and such arrangements may be either applicable generally or only in specific cases. 

(l)    No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or
separate fund of any kind or a fiduciary relationship between the Company or any Affiliate, on the one hand, and a Participant or other Person, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of
satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company maintain separate bank accounts, books, records
or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as
they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other employees under general law. This Plan is not subject to the federal Employee Retirement Income Security Act of
1974, as amended (ERISA). 
 (m)    Reliance on Reports. Each member of the Committee and each member of the
Board shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of the Company and its
Affiliates and/or any other information furnished in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself or herself. 

(n)    Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any
benefits under any pension, retirement, profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan. 

(o)    Governing Law. The Plan shall be governed by and construed in accordance with the internal laws of the State
of Delaware, without giving effect to the conflict of laws provisions. 
 (p)    Severability. If any provision
of the Plan or any Award or Award agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable by
the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the
Award, such provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan and any such Award shall remain in full force and effect. 

  
 17 

 (q)    Obligations Binding on and Inurement to Successors. The
obligations of the Company under the Plan shall be binding upon and inure to the benefit of any successor corporation or organization resulting from the merger, amalgamation, consolidation or other reorganization of the Company, or upon any
successor corporation or organization succeeding to substantially all of the assets and business of the Company. 

(r)    [Reserved.] 

(s)    Expenses; Gender; Titles and Headings. The expenses of administering the Plan shall be borne by the Company
and its Affiliates. Masculine pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text
of the Plan, rather than such titles or headings shall control. 
 (t)    Other Agreements. Notwithstanding
anything herein or in any Award agreement to the contrary, in no event will shares of Common Stock be delivered upon vesting, exercise or settlement of any Award granted under the Plan unless and until the Participant, as requested by the Committee,
executes a joinder (or similar arrangement) whereby such Participant will become bound by the terms and conditions set forth in any stockholder agreements then applicable to the holders of the Company’s Common Stock (other than de minimis
holders, i.e., holders of less than one percent (1%) of the Company’s Common Stock calculated on a fully-diluted basis), such that the Participant shall be subject to (i) the same obligations, including with respect to drag-along
obligations, rights of first refusal, voting agreements, and lock-up agreements, on the same terms and conditions as are then applicable to such holders of the Company’s Common Stock and (ii) other
customary restrictions that are applicable to officers and directors of the Company as a matter of law or in connection with a public offering of the Company’s Common Stock. 

(u)    Payments. Participants shall be required to pay, to the extent required by applicable law, any
amounts required to receive shares of Common Stock under any Award made under the Plan. 

(v)    Section 409A. The Plan and the Awards hereunder are intended to either comply
with, or be exempt from, the requirements of Section 409A of the Code. To the extent that the Plan or any Award is not exempt from the requirements of Section 409A of the Code, the Plan and any such Award intended to comply with the
requirements of Section 409A of the Code shall be limited, construed and interpreted in accordance with such intent. Notwithstanding the foregoing, in no event whatsoever shall the Company be liable for any additional tax, interest or penalty
that may be imposed by Section 409A of the Code or any damages relating to any failure to comply with Section 409A of the Code. Each payment or benefit under the Plan shall constitute a separate payment for purposes of Section 409A of
the Code. 
 (w)    Offset. Any amounts owed to the Company or an Affiliate by a Participant of whatever nature
may be offset by the Company from the value of any Common Stock, cash or other thing of value under this Plan or an agreement to be transferred to the Participant, and no Common Stock, cash or other thing of value under this Plan or an agreement
shall be transferred unless and until all disputes between the Company (or its Affiliates) and the Participant have been fully and finally resolved and the Participant has waived all claims to such against the Company and any Affiliate. Any such
offset or delay will be made in a manner that does violate Section 409A of the Code, as may be applicable. 

  
 18 

 (x)    Data Privacy. As a condition of receipt of any
Award, each Participant explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this subsection by and among, as applicable, the Company and its Affiliates for the
exclusive purpose of implementing, administering and managing the Participant’s participation in this Plan. The Company and its Affiliates may hold certain personal information about a Participant, including but not limited to, the
Participant’s name, home address and telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), any shares held in the Company or any of its subsidiaries and
affiliates, details of all Awards, in each case, for the purpose of implementing, managing and administering this Plan and Awards (the “Data”). The Company and its Affiliates may transfer the Data amongst themselves as necessary for
the purpose of implementation, administration and management of a Participant’s participation in this Plan, and the Company and its Affiliates may each further transfer the Data to any third parties assisting the Company and its Affiliates in
the implementation, administration and management of this Plan. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the
recipients’ country. Through acceptance of an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing
the Participant’s participation in this Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Company or its Affiliates, or the Participant, may elect to deposit any Common Stock.
The Data related to a Participant will be held only as long as is necessary to implement, administer, and manage the Participant’s participation in this Plan. A Participant may, at any time, view the Data held by the Company or its Affiliates
with respect to such Participant, request additional information about the storage and processing of the Data with respect to such Participant, recommend any necessary corrections to the Data with respect to the Participant or refuse or withdraw the
consents herein in writing, in any case without cost, by contacting his or her local human resources representative. 

(y)    Expiration. Awards may only be exercised in accordance with the terms of the applicable Award agreement
and/or the Plan, and no Award will be automatically exercised, including in connection with the expiration thereof. Participants are required to exercise any Awards, subject to their terms, in a manner consistent with the terms of the Plan including
this Section 11(y). Any Awards not so exercised will expire without being exercised or the payment of consideration or proceeds therefor. The Company and its Affiliates will not be obligated to notify Participants of Awards that are expiring
and will have no liability for any Awards that expire unexercised.

 Exhibit 10.4 

 

HARMONY BIOSCIENCES HOLDINGS, INC. 

2020 INCENTIVE AWARD PLAN 

ARTICLE I. 
 PURPOSE

 The Plan’s purpose is to enhance the Company’s ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing these individuals with equity ownership opportunities and/or equity-linked compensatory opportunities. Capitalized terms used in the Plan are defined in Article XI. 

ARTICLE II. 
 ELIGIBILITY

 Service Providers are eligible to be granted Awards under the Plan, subject to the limitations described herein. 

ARTICLE III. 

ADMINISTRATION AND DELEGATION 

3.1    Administration. The Plan is administered by the Administrator. The Administrator has authority to determine
which Service Providers receive Awards, grant Awards and set Award terms and conditions, subject to the conditions and limitations in the Plan. The Administrator also has the authority to take all actions and make all determinations under the Plan,
to interpret the Plan and Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The Administrator may correct defects and ambiguities, supply omissions and reconcile
inconsistencies in the Plan or any Award Agreement as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the Plan are in its sole discretion and will be final and binding on all
persons having or claiming any interest in the Plan or any Award. 
 3.2    Appointment of Committees. To the
extent Applicable Laws permit, the Board or the Administrator may delegate any or all of its powers under the Plan to one or more Committees or committees of officers of the Company or any of its Subsidiaries. The Board or the Administrator, as
applicable, may rescind any such delegation, abolish any such committee or Committee and/or re-vest in itself any previously delegated authority at any time. 

ARTICLE IV. 
 STOCK
AVAILABLE FOR AWARDS 
 4.1    Number of Shares. Subject to adjustment under Article VIII and the terms
of this Article IV, the maximum number of Shares that may be issued pursuant to Awards under the Plan shall be equal to the Overall Share Limit. As of the Effective Date, the Company will cease granting awards under the Prior Plan; however,
Prior Plan Awards will remain subject to the terms of the applicable Prior Plan. Shares issued under the Plan may consist of authorized but unissued Shares, Shares purchased on the open market or treasury Shares. 

4.2    Share Recycling. If all or any part of an Award or Prior Plan Award expires, lapses or is terminated,
exchanged for or settled in cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the

 
Award or Prior Plan Award at a price not greater than the price (as adjusted to reflect any Equity Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the
Award or Prior Plan Award, the unused Shares covered by the Award or Prior Plan Award will, as applicable, become or again be available for Award grants under the Plan. In addition, Shares delivered (either by actual delivery or attestation) to the
Company by a Participant to satisfy the applicable exercise or purchase price of an Award or Prior Plan Award and/or to satisfy any applicable tax withholding obligation with respect to an Award (including Shares retained by the Company from the
Award or Prior Plan Award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again be available for Award grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any
outstanding Awards shall not count against the Overall Share Limit. Notwithstanding anything to the contrary contained herein, the following Shares shall not be added to the Shares authorized for grant under Section 4.1 and shall not be
available for future grants of Awards: (i) Shares subject to a Stock Appreciation Right that are not issued in connection with the stock settlement of the Stock Appreciation Right on exercise thereof; and (ii) Shares purchased on the open
market with the cash proceeds from the exercise of Options. 
 4.3    Incentive Stock Option Limitations.
Notwithstanding anything to the contrary herein, no more than 35,000,000 Shares may be issued pursuant to the exercise of Incentive Stock Options. 

4.4    Substitute Awards. In connection with an entity’s merger or consolidation with the Company or the
Company’s acquisition of an entity’s property or stock, the Administrator may grant Awards in substitution for any options or other stock or stock-based awards granted before such merger or consolidation by such entity or its affiliate.
Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares subject to a Substitute
Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of Shares that may be issued pursuant to the
exercise of Incentive Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a
pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such
pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration
payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not
be added to the Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees, Consultants or Directors prior to such acquisition or combination. 

4.5    Non-Employee Director Compensation. Notwithstanding any provision to
the contrary in the Plan, the Administrator may establish compensation for non-employee Directors from time to time, subject to the limitations in the Plan. The sum of any cash compensation, or other
compensation, and the value (determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of Awards granted to a
non-employee Director as compensation for services as a non-employee Director during any fiscal year of the Company may not exceed $750,000 increased to $1,000,000 in
the fiscal year of a non-employee Director’s initial service as a non-employee Director (the “Director Limit”).

 ARTICLE V. 

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS 

5.1    General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to
the limitations in the Plan, including any limitations in the Plan that apply to Incentive Stock Options. A Stock Appreciation Right will entitle the Participant (or other person entitled to exercise the Stock Appreciation Right) to receive from the
Company upon exercise of the exercisable portion of the Stock Appreciation Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the exercise price per Share of the Stock
Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right is exercised, subject to any limitations of the Plan or that the Administrator may impose and payable in cash, Shares valued at Fair Market Value or a
combination of the two as the Administrator may determine or provide in the Award Agreement. 
 5.2    Exercise
Price. The Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and specify the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the
grant date of the Option (subject to Section 5.6) or Stock Appreciation Right. Notwithstanding the foregoing, in the case of an Option or a Stock Appreciation Right that is a Substitute Award, the exercise price per share of the Shares subject
to such Option or Stock Appreciation Right, as applicable, may be less than the Fair Market Value per share on the date of grant; provided that the exercise price of any Substitute Award shall be determined in accordance with the applicable
requirements of Sections 424 and 409A of the Code. 
 5.3    Duration. Each Option or Stock Appreciation Right
will be exercisable at such times and as specified in the Award Agreement, provided that, subject to Section 5.6, the term of an Option or Stock Appreciation Right will not exceed ten years. Notwithstanding the foregoing and unless determined
otherwise by the Company, in the event that on the last business day of the term of an Option or Stock Appreciation Right (other than an Incentive Stock Option) (i) the exercise of the Option or Stock Appreciation Right is prohibited by
Applicable Law, as determined by the Company, or (ii) Shares may not be purchased or sold by the applicable Participant due to any Company insider trading policy (including blackout periods) or a
“lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Option or Stock Appreciation Right shall be extended until the date that is 30 days after
the end of the legal prohibition, black-out period or lock-up agreement, as determined by the Company; provided, however, in no event shall the extension last beyond the
ten year term of the applicable Option or Stock Appreciation Right. Notwithstanding the foregoing, to the extent permitted under Applicable Laws, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right, violates the
non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, confidentiality and nondisclosure
agreement or other agreement between the Participant and the Company or any of its Subsidiaries, the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall
terminate immediately upon such violation, unless the Company otherwise determines. 
 5.4    Exercise. Options
and Stock Appreciation Rights may be exercised by delivering to the Company a written notice of exercise, in a form the Administrator approves (which may be electronic), signed by the person authorized to exercise the Option or Stock Appreciation
Right, together with, as applicable, payment in full (i) as specified in Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the
Administrator otherwise determines, an Option or Stock Appreciation Right may not be exercised for a fraction of a Share. 

  
 3 

 5.5    Payment Upon Exercise. Subject to
Section 10.8, any Company insider trading policy (including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by: 

(a)    cash, wire transfer of immediately available funds or by check payable to the order of the Company, provided that
the Company may limit the use of one of the foregoing payment forms if one or more of the payment forms below is permitted; 

(b)    if there is a public market for Shares at the time of exercise, unless the Company otherwise determines,
(A) delivery (including electronically or telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to pay
the exercise price, or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to pay the
exercise price; provided that such amount is paid to the Company at such time as may be required by the Administrator; 

(c)    to the extent permitted by the Administrator, delivery (either by actual delivery or attestation) of Shares owned
by the Participant valued at their Fair Market Value; 
 (d)    to the extent permitted by the Administrator,
surrendering Shares then issuable upon the Option’s exercise valued at their Fair Market Value on the exercise date; 

(e)    to the extent permitted by the Administrator, delivery of a promissory note or any other property that the
Administrator determines is good and valuable consideration; or 
 (f)    to the extent permitted by the Company, any
combination of the above payment forms approved by the Administrator. 
 5.6    Additional Terms of Incentive Stock
Options. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code, respectively, and any
other entities the employees of which are eligible to receive Incentive Stock Options under the Code. If an Incentive Stock Option is granted to a Greater Than 10% Stockholder, the exercise price will not be less than 110% of the Fair Market Value
on the Option’s grant date, and the term of the Option will not exceed five years. All Incentive Stock Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive Stock Option, the
Participant agrees to give prompt notice to the Company of dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or
(ii) one year after the transfer of such Shares to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in
such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive stock option” under
Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares
having a fair market value exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Stock Option. 

  
 4 

 ARTICLE VI. 

RESTRICTED STOCK; RESTRICTED STOCK UNITS 

6.1    General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any
Service Provider, subject to the Company’s right to repurchase all or part of such Shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such Shares) if conditions the Administrator
specifies in the Award Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers Restricted Stock
Units, which may be subject to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. 

6.2    Restricted Stock. 

(a)    Dividends. Participants holding Shares of Restricted Stock will be entitled to all ordinary cash dividends
paid with respect to such Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend or
distribution to holders of Common Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to
which they were paid. Notwithstanding anything to the contrary herein, with respect to any award of Restricted Stock, dividends which are paid to holders of Common Stock prior to vesting shall only be paid out to the Participant holding such
Restricted Stock to the extent that the vesting conditions are subsequently satisfied. All such dividend payments will be made no later than March 15 of the calendar year following the calendar year in which the right to the dividend payment
becomes nonforfeitable. 
 (b)    Stock Certificates. The Company may require that the Participant deposit in
escrow with the Company (or its designee) any stock certificates issued in respect of Shares of Restricted Stock, together with a stock power endorsed in blank. 

6.3    Restricted Stock Units. 

(a)    Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as
soon as reasonably practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election, in a manner intended to comply with Section 409A. 

(b)    Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any
Restricted Stock Unit unless and until the Shares are delivered in settlement of the Restricted Stock Unit. 
 ARTICLE VII. 

OTHER STOCK OR CASH BASED AWARDS; DIVIDEND EQUIVALENTS 

7.1    Other Stock or Cash Based Awards. Other Stock or Cash Based Awards may be granted to Participants, including
Awards entitling Participants to receive Shares to be delivered in the future and including annual or other periodic or long-term cash bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any
conditions and limitations in the Plan. Such Other Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is
otherwise entitled. Other Stock or Cash Based Awards may be paid in Shares, cash or other property, as the Administrator determines. 

  
 5 

 7.2    Dividend Equivalents. A grant of Restricted Stock Units or
Other Stock or Cash Based Award may provide a Participant with the right to receive Dividend Equivalents, and no Dividend Equivalents shall be payable with respect to Options or Stock Appreciation Rights. Dividend Equivalents may be paid currently
or credited to an account for the Participant, settled in cash or Shares and subject to the same restrictions on transferability and forfeitability as the Award with to which the Dividend Equivalents are paid and subject to other terms and
conditions as set forth in the Award Agreement. Notwithstanding anything to the contrary herein, Dividend Equivalents with respect to an Award shall only paid out to the Participant to the extent that the vesting conditions are subsequently
satisfied. All such Dividend Equivalent payments will be made no later than March 15 of the calendar year following calendar year in which the right to the Dividend Equivalent payment becomes nonforfeitable, unless determined otherwise by the
Administrator or unless deferred in a manner intended to comply with Section 409A. 
 ARTICLE VIII. 

ADJUSTMENTS FOR CHANGES IN COMMON STOCK 

AND CERTAIN OTHER EVENTS 

8.1    Equity Restructuring. In connection with any Equity Restructuring,
notwithstanding anything to the contrary in this Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of
securities subject to each outstanding Award and/or the Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1
will be nondiscretionary and final and binding on the affected Participant and the Company; provided that the Administrator will determine whether an adjustment is equitable. 

8.2    Corporate Transactions. In the event of any dividend or other distribution (whether in the form of cash,
Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially
all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, other similar corporate
transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable Laws or accounting principles, the Administrator, on such terms and conditions as it deems
appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in Applicable Law or accounting principles may be made within a reasonable period of
time after such change) and either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to
(x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or
event or (z) give effect to such changes in Applicable Laws or accounting principles: 
 (a)    To provide for the
cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the
Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s
rights, in any case, is equal to or less than zero, then the Award may be terminated without payment; 

  
 6 

 (b)    To provide that such Award shall vest and, to the extent
applicable, be exercisable as to all Shares covered thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award; 

(c)    To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof,
or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and/or applicable exercise or purchase price, in
all cases, as determined by the Administrator; 
 (d)    To make adjustments in the number and type of Shares (or other
securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in Article IV on the maximum number and kind of shares which
may be issued) and/or in the terms and conditions of (including the grant or exercise price or applicable performance goals), and the criteria included in, outstanding Awards; 

(e)    To replace such Award with other rights or property selected by the Administrator; and/or 

(f)    To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable
event. 
 8.3    Effect of Non-Assumption in a Change in Control. 

(a)    Notwithstanding the provisions of Section 8.2, if a Change in Control occurs and a Participant’s Awards
are not continued, converted, assumed, or replaced with a substantially similar award by (a) the Company, or (b) a successor entity or its parent or subsidiary (an “Assumption”), and provided that the Participant
has not had a Termination of Service, then, immediately prior to the Change in Control, such Awards shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such Awards shall
lapse, in which case, such Awards shall be canceled upon the consummation of the Change in Control in exchange for the right to receive the Change in Control consideration payable to other holders of Common Stock (i) which may be on such terms
and conditions as apply generally to holders of Common Stock under the Change in Control documents (including, without limitation, any escrow, earn-out or other deferred consideration provisions) or such other
terms and conditions as the Administrator may provide, and (ii) determined by reference to the number of Shares subject to such Awards and net of any applicable exercise price; provided that to the extent that any Awards constitute
“nonqualified deferred compensation” that may not be paid upon the Change in Control under Section 409A without the imposition of taxes thereon under Section 409A, the timing of such payments shall be governed by the applicable
Award Agreement (subject to any deferred consideration provisions applicable under the Change in Control documents); and provided, further, that if the amount to which the Participant would be entitled upon the settlement or exercise of such Award
at the time of the Change in Control is equal to or less than zero, then such Award may be terminated without payment. The Administrator shall determine whether an Assumption of an Award has occurred in connection with a Change in Control. 

(b)    If a Change in Control occurs and a Participant’s Awards have been assumed pursuant to Section 8.3(a),
and if, on or within 12 months following such Change in Control, the Company or its successor entity or a parent or subsidiary thereof terminates such Participant’s employment or service with such entity for any reason (other than for Cause and
other than as a result of such Participant’s death or Disability), then (A) such Participant’s remaining unvested Awards (including any Substitute Awards) shall become fully vested, exercisable and/or payable, as applicable, and all
forfeiture, repurchase and other 

  
 7 

 
restrictions on such Awards (including any Substitute Awards) shall lapse, on the date of such Termination of Service, and (B) with respect to Options then held by such Participant, the
Participant shall have a period of six months following the date of such Termination of Service (or such longer period as may be set forth in the applicable Award Agreement(s)) to exercise such Options, to the extent that he or she was otherwise
entitled to exercise such Options on the date of such Termination of Service. 
 8.4    Administrative Stand
Still. In the event of any pending stock dividend, stock split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other extraordinary
transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the
exercise of any Award for up to 60 days before or after such transaction. 
 8.5    General. Except as expressly
provided in the Plan or the Administrator’s action under the Plan, no Participant will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class
or dissolution, liquidation, merger, or consolidation of the Company or other corporation. Except as expressly provided with respect to an Equity Restructuring under Section 8.1 or the Administrator’s action under the Plan, no issuance by
the Company of Shares of any class, or securities convertible into Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the
Plan, any Award Agreements and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s
capital structure or its business, (ii) any merger, consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the
Shares or securities convertible into or exchangeable for Shares. The Administrator may treat Participants and Awards (or portions thereof) differently under this Article VIII. 

ARTICLE IX. 
 GENERAL
PROVISIONS APPLICABLE TO AWARDS 
 9.1    Transferability. Except as the Administrator may determine or
provide in an Award Agreement or otherwise for Awards other than Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except for certain beneficiary
designations, by will or the laws of descent and distribution, or, subject to the Administrator’s consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. Any
permitted transfer of an Award hereunder shall be without consideration, except as required by Applicable Law. References to a Participant, to the extent relevant in the context, will include references to a Participant’s authorized transferee
that the Administrator specifically approves. 
 9.2    Documentation. Each Award will be evidenced in an Award
Agreement, which may be written or electronic, as the Administrator determines. The Award Agreement will contain the terms and conditions applicable to an Award. Each Award may contain terms and conditions in addition to those set forth in the Plan.

 9.3    Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in
relation to any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 

  
 8 

 9.4    Termination of Status. The Administrator will determine
how the disability, death, retirement, an authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which the Participant, the
Participant’s legal representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable. 

9.5    Withholding. Each Participant must pay the Company, or make provision satisfactory to the Administrator for
payment of, any taxes required by Applicable Law to be withheld in connection with such Participant’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based
on the applicable statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a Participant. In the absence of a contrary
determination by the Company (or, with respect to withholding pursuant to clause (ii) below with respect to Awards held by individuals subject to Section 16 of the Exchange Act, a contrary determination by the Administrator), all tax
withholding obligations will be calculated based on the maximum applicable statutory withholding rates. Subject to Section 10.8 and any Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations
(i) in cash, by wire transfer of immediately available funds, by check made payable to the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the payment forms below is permitted,
(ii) to the extent permitted by the Administrator, in whole or in part by delivery of Shares, including Shares delivered by attestation and Shares retained from the Award creating the tax obligation, valued at their Fair Market Value on the
date of delivery, (iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including electronically or telephonically to the extent permitted by the
Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of
irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be
required by the Administrator, or (iv) to the extent permitted by the Company, any combination of the foregoing payment forms approved by the Administrator. Notwithstanding any other provision of the Plan, the number of Shares which may be so
delivered or retained pursuant to clause (ii) of the immediately preceding sentence shall be limited to the number of Shares which have a Fair Market Value on the date of delivery or retention no greater than the aggregate amount of such
liabilities based on the maximum individual statutory tax rate in the applicable jurisdiction at the time of such withholding (or such other rate as may be required to avoid the liability classification of the applicable award under generally
accepted accounting principles in the United States of America); provided, however, to the extent such Shares were acquired by Participant from the Company as compensation, the Shares must have been held for the minimum period required by applicable
accounting rules to avoid a charge to the Company’s earnings for financial reporting purposes; provided, further, that, any such Shares delivered or retained shall be rounded up to the nearest whole Share to the extent rounding up to the
nearest whole Share does not result in the liability classification of the applicable Award under generally accepted accounting principles in the United States of America. If any tax withholding obligation will be satisfied under clause
(ii) above by the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company may elect to instruct any brokerage firm determined
acceptable to the Company for such purpose to sell on the applicable Participant’s behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an
Award under the Plan will constitute the Participant’s authorization to the Company and instruction and authorization to such brokerage firm to complete the transactions described in this sentence. 

9.6    Amendment of Award; Repricing. The Administrator may amend, modify or terminate any outstanding Award,
including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Stock Option to a Non-Qualified Stock Option. The
Participant’s consent to such action will be required unless (i) the action, taking into account any related 

  
 9 

 
action, does not materially and adversely affect the Participant’s rights under the Award, or (ii) the change is permitted under Article VIII or pursuant to Section 10.6.
Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may, without the approval of the stockholders of the Company, (i) reduce the exercise price per share of outstanding Options or Stock Appreciation Rights
or (ii) cancel outstanding Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation Rights with an exercise price per share that is less than the exercise price per share of the original Options
or Stock Appreciation Rights. 
 9.7    Conditions on Delivery of Stock. The Company will not be obligated to
deliver any Shares under the Plan or remove restrictions from Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all
other legal matters regarding the issuance and delivery of such Shares have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered
to the Company such representations or agreements as the Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the
Administrator determines is necessary to the lawful issuance and sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been obtained. 

9.8    Acceleration. The Administrator may at any time provide that any Award will become immediately vested and
fully or partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable. 

9.9    Cash Settlement. Without limiting the generality of any other provision of the Plan, the Administrator may
provide, in an Award Agreement or subsequent to the grant of an Award, in its discretion, that any Award may be settled in cash, Shares or a combination thereof. 

9.10    Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in connection with the payment of
amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (i) any Shares to be sold through the broker-assisted sale will be sold on the day the payment
first becomes due, or as soon thereafter as practicable; (ii) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an average price; (iii) the applicable Participant will be
responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (iv) to the
extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably practicable; (v) the Company and its designees are under
no obligation to arrange for such sale at any particular price; and (vi) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable obligation, the Participant may be required to pay immediately upon
demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation. 

ARTICLE X. 

MISCELLANEOUS 

10.1    No Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and
the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the Company or any of its Subsidiaries. The Company and its Subsidiaries expressly reserves the right at any time to
dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an Award Agreement or in the Plan. 

  
 10 

 10.2    No Rights as Stockholder; Certificates. Subject to the
Award Agreement, no Participant or Designated Beneficiary will have any rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the
Plan, unless the Administrator otherwise determines or Applicable Laws require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded
in the books of the Company (or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with
Applicable Laws. 
 10.3    Effective Date and Term of Plan. Unless earlier terminated by the Board, the Plan
will become effective on the day prior to the Public Trading Date (the “Effective Date”) and will remain in effect until the tenth anniversary of the earlier of (i) the date the Board adopted the Plan or (ii) the
date the Company’s stockholders approved the Plan, but Awards previously granted may extend beyond that date in accordance with the Plan. Notwithstanding anything to the contrary in the Plan, an Incentive Stock Option may not be granted under
the Plan after 10 years from the earlier of (i) the date the Board adopted the Plan or (ii) the date the Company’s stockholders approved the Plan, but Awards previously granted may extend beyond that date in accordance with the Plan.
If the Plan is not approved by the Company’s stockholders, the Plan will not become effective, no Awards will be granted under the Plan and the Prior Plan will continue in full force and effect in accordance with its terms. 

10.4    Amendment of Plan. The Board may amend, suspend or terminate the Plan at any time; provided that no
amendment, other than an increase to the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted under the Plan during any
suspension period or after the Plan’s termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or termination. The
Board will obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws. 

10.5    Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are
foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters. 
 10.6    Section 409A. 

(a)    General. The Company intends that all Awards be structured to comply with, or be exempt from,
Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent,
amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any
such actions intended to (A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an
Award’s grant date. The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to avoid the taxes,
penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant
“nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A. 

  
 11 

 (b)    Separation from Service. If an Award constitutes
“nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under
Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the
Participant’s Service Provider relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a
“separation from service.” 
 (c)    Payments to Specified Employees. Notwithstanding any contrary
provision in the Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator
determines) due to his or her “separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period immediately
following such “separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such
six-month period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six months following
the Participant’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be made. 

10.7    Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a
director, officer, other employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the
Plan or any Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator, director, officer, other employee or agent of the Company
or any Subsidiary. The Company will indemnify and hold harmless each director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or delegated any duty or power relating to the Plan’s
administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission concerning this
Plan unless arising from such person’s own fraud or bad faith. 

10.8    Lock-Up Period. The Company may, at the request of any underwriter
representative or otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly, selling or otherwise transferring any Shares or other Company securities
during a period of up to 180 days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter. 

10.9    Data Privacy. As a condition for receiving any Award, each Participant explicitly and unambiguously
consents to the collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Subsidiaries and affiliates exclusively for implementing, administering and managing the
Participant’s participation in the Plan. The Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate; social security,
insurance number or other identification number; salary; nationality; job title(s); any Shares held in the Company or its Subsidiaries and affiliates; and Award details, to implement, manage and administer the Plan and Awards (the
“Data”). The Company and its Subsidiaries and affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in the Plan, and the Company and its
Subsidiaries and affiliates may transfer the Data to third parties assisting the Company with Plan implementation, administration and management. These recipients may be located in the Participant’s country, or elsewhere, and the
Participant’s country may have different data privacy laws and protections 

  
 12 

 
than the recipients’ country. By accepting an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to
implement, administer and manage the Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit any Shares. The Data related to a
Participant will be held only as long as necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company holds regarding such Participant, request
additional information about the storage and processing of the Data regarding such Participant, recommend any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this Section 10.9 in writing,
without cost, by contacting the local human resources representative. If the Participant refuses or withdraws the consents in this Section 10.9, the Company may cancel Participant’s ability to participate in the Plan and, in the
Administrator’s discretion, the Participant may forfeit any outstanding Awards. For more information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources representative. 

10.10    Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any
reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void.

 10.11    Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other
written agreement between a Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision of
the Plan will not apply. 
 10.12    Governing Law. The Plan and all Awards will be governed by and interpreted
in accordance with the laws of the State of Delaware, disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws
other than the State of Delaware. 
 10.13    Claw-back Provisions. All Awards (including, without limitation,
any proceeds, gains or other economic benefit actually or constructively received by Participant upon any receipt or exercise of any Award or upon the receipt or resale of any Shares underlying the Award) shall be subject to the provisions of any
claw-back policy implemented by the Company, including, without limitation, any claw-back policy adopted to comply with Applicable Laws (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated
thereunder) as and to the extent set forth in such claw-back policy or the Award Agreement. 
 10.14    Titles and
Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict, the Plan’s text, rather than such titles or headings, will control. 

10.15    Conformity to Securities Laws. Participant acknowledges that the Plan is intended to conform to the extent
necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award Agreements will be
deemed amended as necessary to conform to Applicable Laws. 
 10.16    Relationship to Other Benefits. No payment
under the Plan will be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as expressly provided in writing in
such other plan or an agreement thereunder.

in Control constitutes a payment event with respect to any Award (or portion of any Award) that provides for the deferral of compensation that is subject to Section 409A, to the extent required to avoid the imposition of additional taxes under

transaction also constitutes a “change in control event,” as defined in Treasury Regulation Section 1.409A-3(i)(5).
