based on such factors, if any, as the Committee shall determine, in its sole discretion); 
 (e) to determine the amount of cash to be
covered by each Award granted hereunder; 
 (f) to determine whether, to what extent and under what circumstances grants of Options and other
Awards under the Plan are to operate on a tandem basis and/or in conjunction with or apart from other awards made by the Company outside of the Plan; 

(g) to determine whether and under what circumstances a Stock Option may be settled in cash, Common Stock and/or Restricted Stock under
Section 6.4(d);

Non-Qualified Stock Option; 

  
 5 

 (i) to determine whether to require a Participant, as a condition of the granting of any
Award, to not sell or otherwise dispose of shares acquired pursuant to the exercise of an Award for a period of time as determined by the Committee, in its sole discretion, following the date of the acquisition of such Award; 

(j) to modify, extend or renew an Award, subject to Article XII and Section 6.4(m); provided, however, that such action does not
subject the Award to Section 409A of the Code without the consent of the Participant; 
 (k) solely to the extent permitted by
applicable law, to determine whether, to what extent and under what circumstances to provide loans (which may be on a recourse basis and shall bear interest at the rate the Committee shall provide) to Participants in order to exercise Options under
the Plan; and 
 (l) to interpret and apply this Plan and any Award granted hereunder. 

3.3 Guidelines. Subject to Article XII hereof, the Committee shall have the authority to adopt, alter and repeal such
administrative rules, guidelines and practices governing the Plan and perform all acts, including the delegation of its responsibilities (to the extent permitted by applicable law and applicable stock exchange rules), as it shall, from time to time,
deem advisable; to construe and interpret the terms and provisions of the Plan and any Award issued under the Plan (and any agreements relating thereto); and to otherwise supervise the administration of the Plan. The Committee may correct any
defect, supply any omission or reconcile any inconsistency in the Plan or in any agreement relating thereto in the manner and to the extent it shall deem necessary to effectuate the purpose and intent of the Plan. The Committee may adopt special
guidelines and provisions for persons who are residing in or employed in, or subject to, the taxes of, any domestic or foreign jurisdictions to comply with applicable tax and securities laws of such domestic or foreign jurisdictions. Notwithstanding
the foregoing, no action of the Committee under this Section 3.3 shall impair the rights of any Participant without the Participant’s consent. 

3.4 Minimum Vesting Period. Notwithstanding anything to the contrary in this Plan, each Award Agreement will require that
an Award be subject to a minimum vesting period of at least one (1) year commencing from the date of grant. For the purpose of clarity, this Section 3.4 will not prevent the Committee from accelerating the vesting of any Award in
accordance with any of the provisions set forth in this Plan. 
 3.5 Decisions Final. Any decision, interpretation or
other action made or taken in good faith by or at the direction of the Company, the Board or the Committee (or any of its members) arising out of or in connection with the Plan shall be within the absolute discretion of all and each of them, as the
case may be, and shall be final, binding and conclusive on the Company and all employees and Participants and their respective heirs, executors, administrators, successors and assigns. The Committee’s determinations and interpretations with
respect to Awards 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. 

3.6 Procedures. If the Committee is appointed, the Board shall designate one of the members of the Committee as chairman
and the Committee shall hold meetings, subject to the By-Laws of the Company, at such times and places as it shall deem advisable, including, without limitation, by telephone conference or by written consent

it shall deem advisable.

 (b) The Committee may employ such legal counsel, consultants and agents as it may deem
desirable for the administration of the Plan and may rely upon any opinion received from any such counsel or consultant and any computation received from any such consultant or agent. Expenses incurred by the Committee or the Board in the engagement
of any such counsel, consultant or agent shall be paid by the Company. The Committee, its members and any person designated pursuant to sub-section (a) above shall not be liable for any action or
determination made in good faith with respect to the Plan. To the maximum extent permitted by applicable law, no officer of the Company or member or former member of the Committee or of the Board shall be liable for any action or determination made
in good faith with respect to the Plan or any Award granted under it. 
 3.8 Indemnification. To the maximum extent
permitted by applicable law and the Certificate of Incorporation and By-Laws of the Company and to the extent not covered by insurance directly insuring such person, each officer or employee of the Company or
any Affiliate and member or former member of the Committee or the Board shall be indemnified and held harmless by the Company against any cost or expense (including reasonable fees of counsel reasonably acceptable to the Committee) or liability
(including any sum paid in settlement of a claim with the approval of the Committee), and advanced amounts necessary to pay the foregoing at the earliest time and to the fullest extent permitted, arising out of any act or omission to act in
connection with the administration of the Plan, except to the extent arising out of such officer’s, employee’s, member’s or former member’s own fraud or bad faith. Such indemnification shall be in addition to any right of
indemnification the employees, officers, directors or members or former officers, directors or members may have under applicable law or under the Certificate of Incorporation or By-Laws of the Company or any
Affiliate. Notwithstanding anything else herein, this indemnification will not apply to the actions or determinations made by an individual with regard to Awards granted to such individual under the Plan. 

ARTICLE IV 
 SHARE
LIMITATION 
 4.1 Shares. 

(a) Share Reserve. Subject to any increase or decrease pursuant to Section 4.2, the aggregate number of shares
of Common Stock that may be issued or used for reference purposes, or with respect to which Awards may be granted, will not exceed 27,500,000 shares (the “Share Reserve”). Shares of Common Stock issued hereunder may be made
available from either authorized and unissued Common Stock, or authorized and issued Common Stock reacquired and held as treasury shares, or otherwise, or a combination thereof. Any shares of Common Stock that are subject to Options or Stock
Appreciation Rights will be counted against the Share Reserve as one (1) share for every one (1) share granted, and any shares of Common Stock that are subject to Restricted Stock, Restricted Stock Unit Awards, Performance Awards or Other
Stock-Based Awards (“Full-Value Awards”) will be counted against the Share Reserve as one (1) share for every one (1) share granted. The maximum number of shares of Common Stock with respect to which
Incentive Stock Options may be granted under the Plan will equal the Share Reserve without regard to adjustments under Section 4.1(c). 

(b) Substitute Awards; Use of Shares Under Acquired Company Plans. Shares of Common Stock issued under Awards granted upon the
assumption, substitution or exchange for previously granted awards of a company acquired by the Company will not reduce the Share Reserve. In addition, the Company may issue Awards under the Plan without a reduction in the Share Reserve with respect
to shares available under an equity incentive plan maintained by a company acquired by the Company in a corporate transaction, as appropriately adjusted to reflect such transaction pursuant to Section 4.2 (subject to all
applicable stock exchange listing requirements). 
 (c) Permitted Addbacks to Share Reserve; Certain Limitations Relating to Options and
SARs. If any Option or Stock Appreciation Right granted under the Plan expires, terminates or is cash-settled or canceled for any reason without having been exercised in full, the number of shares of Common Stock underlying any such Award will
again be available for Awards under the Plan. If any Full-Value Awards granted under the Plan are forfeited or cash-settled for any reason, the number of such forfeited or cash-settled shares of Common Stock will again be available for Awards under
the Plan. Any shares of Common Stock that again become available for Awards under the Plan pursuant to this Section 4.1(c) will be added as (i) one (1) share of Common Stock for every one (1) share subject to Options or Stock
Appreciation Rights granted under the Plan, and (ii) as one (1) share of Common Stock for every one (1) share subject to Full-Value Awards granted under the Plan. Notwithstanding anything to the contrary contained

  
 7 

 
herein, the following shares of Common Stock will not be added to the Share Reserve: (i) shares of Common Stock tendered by the Participant or withheld by the Company in payment of the
purchase price of an Option under the Plan, (ii) shares of Common Stock tendered by the Participant or withheld by the Company to satisfy any tax withholding obligations with respect to any Awards under the Plan, (iii) shares of Common
Stock subject to a Stock Appreciation Right under the Plan that are not issued in connection with its stock settlement on exercise thereof, and (iv) shares of Common Stock reacquired by the Company on the open market or otherwise using cash
proceeds from the exercise of Options under the Plan. 
 (d) The existence of the Plan and the 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 (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger
or consolidation of the Company or any Affiliate, (iii) any issuance of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock, (iv) the dissolution or liquidation of the Company or any Affiliate,
(v) any sale or transfer of all or part of the assets or business of the Company or any Affiliate or (vi) any other corporate act or proceeding. 

(e) Subject to the provisions of Section 11.1: 

(i) If the Company at any time subdivides (by any split, recapitalization or otherwise) the outstanding Common Stock into a greater number of
shares of Common Stock, or combines (by reverse split, combination or otherwise) its outstanding Common Stock into a lesser number of shares of Common Stock, then the respective exercise prices for outstanding Awards that provide for a Participant
elected exercise, the number of shares of Common Stock covered by outstanding Awards and the number of shares of Common Stock reserved for issuance under the Plan shall be appropriately adjusted by the Committee to prevent dilution or enlargement of
the rights granted to, or available for, Participants under the Plan. 
 (ii) Excepting transactions covered by Section 4.2(b)(i), if
the Company effects any merger, consolidation, statutory exchange, spin-off, reorganization, sale or transfer of all or substantially all the Company’s assets or business, or other corporate transaction
or event in such a manner that the Company’s outstanding shares of Common Stock are converted into the right to receive (or the holders of Common Stock are entitled to receive in exchange therefor), either immediately or upon liquidation of the
Company, securities or other property of the Company or other entity (each, a “Reorganization”), then, subject to the provisions of Section 11.1, (A) the aggregate number or kind of securities that thereafter may be
issued under the Plan, (B) the number or kind of securities or other property (including cash) to be issued pursuant to Awards granted under the Plan (including as a result of the assumption of the Plan and the obligations hereunder by a
successor entity, as applicable), or (C) the purchase price thereof, shall be appropriately adjusted by the Committee to prevent dilution or enlargement of the rights granted to, or available for, Participants under the Plan. 

(iii) If there shall occur any change in the capital structure of the Company other than those covered by Section 4.2(b)(i) or
4.2(b)(ii), including by reason of any extraordinary dividend (whether cash or equity), any conversion, any adjustment, any issuance of any class of securities convertible or exercisable into, or exercisable for, any class of equity securities of
the Company, then the Committee shall adjust any Award and make such other adjustments to the Plan to prevent dilution or enlargement of the rights granted to, or available for, Participants under the Plan. 

(iv) Any such adjustment determined by the Committee pursuant to this Section 4.2(b) shall be final, binding and conclusive on the
Company and all Participants and their respective heirs, executors, administrators, successors and permitted assigns. Any adjustment to, or assumption or substitution of, an Award under this Section 4.2(b) shall be intended to comply with the
requirements of Section 409A of the Code and Treasury Regulation §1.424-1 (and any amendments thereto), to the extent applicable. Except as expressly provided in this Section 4.2 or in the
applicable Award Agreement, a Participant shall have no additional rights under the Plan by reason of any transaction or event described in this Section 4.2. 

(v) Fractional shares of Common Stock resulting from any adjustment in Awards pursuant to Section 4.2(a) or this Section 4.2(b)
shall be aggregated until, and eliminated at, the time of exercise or payment by rounding-down for fractions less than one-half and rounding-up for fractions equal to or
greater than one-half. No cash settlements shall be required with respect to fractional shares eliminated by rounding. Notice of any adjustment shall be given by the Committee to each Participant whose Award has been adjusted and such adjustment
(whether or not such notice is given) shall be effective and binding for all purposes of the Plan. 

  
 8 

 4.2 Minimum Purchase Price. Notwithstanding any provision of the Plan
to the contrary, if authorized but previously unissued shares of Common Stock are issued under the Plan, such shares shall not be issued for a consideration that is less than as permitted under applicable law.

Eligibility for the grant of Awards and actual participation in the Plan shall be determined by the Committee in its sole discretion. 

5.2 Incentive Stock Options. Notwithstanding the foregoing, only Eligible Employees of the Company, its Subsidiaries and
its Parent (if any) are eligible to be granted Incentive Stock Options under the Plan. Eligibility for the grant of an Incentive Stock Option and actual participation in the Plan shall be determined by the Committee in its sole discretion.

ARTICLE VI 
 STOCK
OPTIONS

Each Stock Option granted under the Plan shall be of one of two types: (a) an Incentive Stock Option or (b) a Non-Qualified Stock Option. 

6.2 Grants. The Committee shall have the authority to grant to any Eligible Employee one or more Incentive Stock Options, Non-Qualified Stock Options, or both types of Stock Options. The Committee shall have the authority to grant any Consultant or Non-Employee Director one or more Non-Qualified Stock Options. To the extent that any Stock Option does not qualify as an Incentive Stock Option (whether because of its provisions or the time or manner of its exercise or otherwise), such Stock
Option or the portion thereof which does not so qualify shall constitute a separate Non-Qualified Stock Option. 

6.3 Incentive Stock Options. Notwithstanding anything in the Plan to the contrary, no term of the Plan relating to
Incentive Stock Options shall be interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be so exercised, so as to disqualify the Plan under Section 422 of the Code, or, without the consent of the
Participants affected, to disqualify any Incentive Stock Option under such Section 422. 
 6.4 Terms of Options.
Options granted under the Plan shall be subject to the following terms and conditions and shall be in such form and contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem desirable:

 (a) Exercise Price. The exercise price per share of Common Stock subject to a Stock Option shall be determined by the Committee at
the time of grant; provided that the per share exercise price of a Stock Option shall not be less than 100% (or, in the case of an Incentive Stock Option granted to a Ten Percent Stockholder, 110%) of the Fair Market Value of the Common Stock
at the time of grant. 
 (b) Stock Option Term. The term of each Stock Option shall be fixed by the Committee; provided that no
Stock Option shall be exercisable more than 10 years after the date the Option is granted; and provided further that the term of an Incentive Stock Option granted to a Ten Percent Stockholder shall not exceed five years. 

  
 9 

 (c) Exercisability. Unless otherwise provided by the Committee in accordance with the
provisions of this Section 6.4, Stock Options granted under the Plan shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Committee at the time of grant. If the Committee provides, in
its discretion, that any Stock Option is exercisable subject to certain limitations (including, without limitation, that such Stock Option is exercisable only in installments or within certain time periods), the Committee may waive such limitations
on the exercisability at any time at or after the time of grant in whole or in part (including, without limitation, waiver of the installment exercise provisions or acceleration of the time at which such Stock Option may be exercised), based on such
factors, if any, as the Committee shall determine, in its sole discretion. 
 (d) Method of Exercise. Subject to whatever installment
exercise and waiting period provisions apply under Section 6.4(c), to the extent vested, Stock Options may be exercised in whole or in part at any time during the Option term, by giving written notice of exercise to the Company specifying the
number of shares of Common Stock to be purchased. Such notice shall be accompanied by payment in full of all applicable withholding taxes and the purchase price as follows: (i) in cash or by check, bank draft or money order payable to the order
of the Company; (ii) solely to the extent permitted by applicable law, if the Common Stock is traded on a national securities exchange, and the Committee authorizes, through a procedure whereby the Participant delivers irrevocable instructions
to a broker reasonably acceptable to the Committee to deliver promptly to the Company an amount equal to the purchase price; or (iii) on such other terms and conditions as may be acceptable to the Committee (including, without limitation, with
the consent of the Committee, having the Company withhold shares of Common Stock issuable upon exercise of the Stock Option, or by payment in full or in part in the form of Common Stock owned by the Participant, based on the Fair Market Value of the
Common Stock on the payment date as determined by the Committee). No shares of Common Stock shall be issued until payment therefor, as provided herein, has been made or provided for. The Committee may prohibit or limit the exercise of Stock Options
at such times and on such conditions it determines. 
 (e) Non-Transferability of Options. No
Stock Option shall be Transferable by the Participant other than by will or by the laws of descent and distribution, and all Stock Options shall be exercisable, during the Participant’s lifetime, only by the Participant. Notwithstanding the
foregoing, the Committee may determine, in its sole discretion, at the time of grant or thereafter that a Non-Qualified Stock Option that is otherwise not Transferable pursuant to this Section is Transferable
to a Family Member in whole or in part and in such circumstances, and under such conditions, as specified by the Committee. A Non-Qualified Stock Option that is Transferred to a Family Member pursuant to the
preceding sentence (i) may not be subsequently Transferred other than by will or by the laws of descent and distribution and (ii) remains subject to the terms of the Plan and the applicable Award Agreement. Any shares of Common Stock
acquired upon the exercise of a Non-Qualified Stock Option by a permissible transferee of a Non-Qualified Stock Option or a permissible transferee pursuant to a Transfer
after the exercise of the Non-Qualified Stock Option shall be subject to the terms of the Plan and the applicable Award Agreement. 

(f) Extension of Termination Date. If the exercise of the Option following the Participant’s Termination for any reason would be
prohibited at any time because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, any other state or federal securities law, the rules of any securities exchange or interdealer quotation
system or any black out period or period of restriction on exercise imposed by the Company (“Exercise Restrictions”), then, to the extent consistent with Section 409A of the Code, the Option shall terminate on the earlier of
(i) the expiration of the term of the Option or (ii) the expiration of a period after the Participant’s Termination that is ninety (90) days after the end of the period during which the Exercise Restrictions are imposed. 

(g) Termination by Death or Disability. Unless otherwise determined by the Committee at the time of grant, or if no rights of the
Participant are reduced, thereafter, if a Participant’s Termination is by reason of death or Disability, all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Termination may
be exercised by the Participant (or in the case of the Participant’s death, by the legal representative of the Participant’s estate) at any time within a period of one (1) year from the date of such Termination, but in no event beyond
the expiration of the stated term of such Stock Options; provided, however, that, in the event of a Participant’s Termination by reason of Disability, if the Participant dies within such exercise period, all unexercised Stock
Options held by such Participant shall thereafter be exercisable, to the extent to which they were exercisable at the time of death, for a period of one (1) year from the date of such death, but in no event beyond the expiration of the stated
term of such Stock Options. 

  
 10 

 (h) Involuntary Termination Without Cause/Resignation with Good Reason. Unless
otherwise determined by the Committee at the time of grant, or if no rights of the Participant are reduced, thereafter, if a Participant’s Termination is by involuntary termination by the Company without Cause or a resignation with Good Reason,
all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Termination may be exercised by the Participant at any time within a period of ninety (90) days from the date of such
Termination, but in no event beyond the expiration of the stated term of such Stock Options. 
 (i) Voluntary Resignation. Unless
otherwise determined by the Committee at the time of grant, or if no rights of the Participant are reduced, thereafter, if a Participant’s Termination is voluntary (other than a voluntary termination described in Section 6.4(j)(y) hereof),
all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Termination may be exercised by the Participant at any time within a period of thirty (30) days from the date of such
Termination, but in no event beyond the expiration of the stated term of such Stock Options. 
 (j) Termination for Cause. Unless
otherwise determined by the Committee at the time of grant, or if no rights of the Participant are reduced, thereafter, if a Participant’s Termination (x) is for Cause or (y) is a voluntary Termination (as provided in
Section 6.4(i)) after the occurrence of an event that would be grounds for a Termination for Cause, all Stock Options, whether vested or not vested, that are held by such Participant shall thereupon terminate and expire as of the date of such
Termination. 
 (k) Unvested Stock Options. Unless otherwise determined by the Committee at the time of grant, or if no rights of the
Participant are reduced, thereafter, Stock Options that are not vested as of the date of a Participant’s Termination for any reason shall terminate and expire as of the date of such Termination. 

(1) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined as of the time of grant) of the
Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an Eligible Employee during any calendar year under the Plan and/or any other stock option plan of the Company, any Subsidiary or any Parent exceeds
$100,000, such Options shall be treated as Non-Qualified Stock Options. In addition, if an Eligible Employee does not remain employed by the Company, any Subsidiary or any Parent at all times from the time an
Incentive Stock Option is granted until three months prior to the date of exercise thereof (or such other period as required by applicable law), such Stock Option shall be treated as a Non-Qualified Stock
Option. Should any provision of the Plan not be necessary in order for the Stock Options to qualify as Incentive Stock Options, or should any additional provisions be required, the Committee may amend the Plan accordingly, without the necessity of
obtaining the approval of the stockholders of the Company. 
 (l) Form, Modification, Extension and Renewal of Stock Options. Subject
to the terms and conditions and within the limitations of the Plan, Stock Options shall be evidenced by such form of agreement or grant as is approved by the Committee, and the Committee may (i) modify, extend or renew outstanding Stock Options
granted under the Plan (provided that the rights of a Participant are not reduced without such Participant’s consent; and provided further that such action does not subject the Stock Options to Section 409A of the Code
without the consent of the Participant), and (ii) accept the surrender of outstanding Stock Options (to the extent not theretofore exercised) and authorize the granting of new Stock Options in substitution therefor (to the extent not
theretofore exercised). 
 (m) Deferred Delivery of Common Stock. The Committee may in its discretion permit Participants to defer
delivery of Common Stock acquired pursuant to a Participant’s exercise of an Option in accordance with the terms and conditions established by the Committee in the applicable Award Agreement, which shall be intended to comply with the
requirements of Section 409A of the Code. 
 (n) Early Exercise. The Committee may provide that a Stock Option include a
provision whereby the Participant may elect at any time before the Participant’s Termination to exercise the Stock Option as to any part or all of the shares of Common Stock subject to the Stock Option prior to the full vesting of the Stock
Option and such shares shall be subject to the provisions of Article VIII and be treated as Restricted Stock. Unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the
Committee determines to be appropriate. 

  
 11 

 (o) Other Terms and Conditions. The Committee may include a provision in an Award
Agreement providing for the automatic exercise of a Non-Qualified Stock Option on a cashless basis on the last day of the term of such Option if the Participant has failed to exercise the Non-Qualified Stock Option as of such date, with respect to which the Fair Market Value of the shares of Common Stock underlying the Non-Qualified Stock Option exceeds the
exercise price of such Non-Qualified Stock Option on the date of expiration of such Option, subject to Section 14.4. Stock Options may contain such other provisions, which shall not be inconsistent with
any of the terms of the Plan, as the Committee shall deem appropriate. 
 ARTICLE VII 

STOCK APPRECIATION RIGHTS 

7.1 Stock Appreciation Rights. Stock Appreciation Rights may also be granted without reference to any Stock Options
granted under the Plan. 
 7.2 Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights granted
hereunder shall be subject to such terms and conditions, not inconsistent with the provisions of the Plan, as shall be determined from time to time by the Committee, and the following: 

(a) Exercise Price. The exercise price per share of Common Stock subject to a Stock Appreciation Right shall be determined by the
Committee at the time of grant; provided that the per share exercise price of a Stock Appreciation Right shall not be less than 100% of the Fair Market Value of the Common Stock at the time of grant. 

(b) Term. The term of each Stock Appreciation Right shall be fixed by the Committee, but shall not be greater than 10 years after the
date the right is granted. 
 (c) Exercisability. Unless otherwise provided by the Committee in accordance with the provisions of this
Section 7.2, Stock Appreciation Rights granted under the Plan shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Committee at the time of grant. If the Committee provides, in its
discretion, that any such right is exercisable subject to certain limitations (including, without limitation, that it is exercisable only in installments or within certain time periods), the Committee may waive such limitations on the exercisability
at any time at or after grant in whole or in part (including, without limitation, waiver of the installment exercise provisions or acceleration of the time at which such right may be exercised), based on such factors, if any, as the Committee shall
determine, in its sole discretion. Notwithstanding the foregoing, Stock Appreciation Rights shall not be exercisable unless and until provision has been made by the Participant to satisfy any applicable taxes required to be withheld upon the
exercise of such Stock Appreciation Right. 
 (d) Method of Exercise. Subject to whatever installment exercise and waiting period
provisions apply under Section 7.2(c), Stock Appreciation Rights may be exercised in whole or in part at any time in accordance with the applicable Award Agreement, by giving written notice of exercise to the Company specifying the number of
Stock Appreciation Rights to be exercised. 
 (e) Payment. Upon the exercise of a Stock Appreciation Right a Participant shall be
entitled to receive, for each right exercised, up to, but no more than, an amount in cash and/or Common Stock (as chosen by the Committee in its sole discretion) equal in value to the excess of the Fair Market Value of one share of Common Stock on
the date that the right is exercised over the Fair Market Value of one share of Common Stock on the date that the right was awarded to the Participant. 

(f) Termination. Unless otherwise determined by the Committee at grant or, if no rights of the Participant are reduced, thereafter,
subject to the provisions of the applicable Award Agreement and the Plan, upon a Participant’s Termination for any reason, Stock Appreciation Rights will remain exercisable following a Participant’s Termination on the same basis as Stock
Options would be exercisable following a Participant’s Termination in accordance with the provisions of Sections 6.4(f) through 6.4(k). 

  
 12 

 (g) Non-Transferability. No Stock
Appreciation Rights shall be Transferable by the Participant other than by will or by the laws of descent and distribution, and all such rights shall be exercisable, during the Participant’s lifetime, only by the Participant. 

7.3 Other Terms and Conditions. The Committee may include a provision in an Award Agreement providing for the automatic
exercise of a Stock Appreciation Right on a cashless basis on the last day of the term of such Stock Appreciation Right if the Participant has failed to exercise the Stock Appreciation Right as of such date, with respect to which the Fair Market
Value of the shares of Common Stock underlying the Stock Appreciation Right exceeds the exercise price of such Stock Appreciation Right on the date of expiration of such Stock Appreciation Right, subject to Section 14.4. Stock Appreciation
Rights may contain such other provisions, which shall not be inconsistent with any of the terms of the Plan, as the Committee shall deem appropriate. 

ARTICLE VIII 
 RESTRICTED
STOCK AND RESTRICTED STOCK UNITS 
 8.1 Awards of Restricted Stock. Shares of Restricted Stock and Restricted Stock
Units may be issued either alone or in addition to other Awards granted under the Plan. The Committee shall determine the Eligible Individuals, to whom, and the time or times at which, grants of Restricted Stock shall be made, the number of shares
to be awarded, the price (if any) to be paid by the Participant (subject to Section 8.2), the time or times within which such Awards may be subject to forfeiture, the vesting schedule and rights to acceleration thereof, and all other terms and
conditions of the Awards. 
 The Committee may condition the grant or vesting of Restricted Stock or Restricted Stock Units upon the
attainment of specified performance targets (including, the Performance Goals) or such other factor as the Committee may determine in its sole discretion. 

8.2 Awards and Certificates. Eligible Individuals selected to receive Restricted Stock or Restricted Stock Units shall not
have any right with respect to such Award, unless and until such Participant has delivered a fully executed copy of the agreement evidencing the Award to the Company, to the extent required by the Committee, and has otherwise complied with the
applicable terms and conditions of such Award. Further, such Award shall be subject to the following conditions: 
 (a) Purchase
Price. The purchase price of Restricted Stock or Restricted Stock Units shall be fixed by the Committee. Subject to Section 4.3, the purchase price for shares of Restricted Stock may be zero to the extent permitted by applicable law, and,
to the extent not so permitted, such purchase price may not be less than par value. 
 (b) Acceptance. Awards of Restricted Stock or
Restricted Stock Units must be accepted within a period of 60 days (or such shorter period as the Committee may specify at grant) after the grant date, by executing a Restricted Stock agreement and, with respect to Restricted Stock Units, by paying
whatever price (if any) the Committee has designated thereunder. 
 (c) Legend. Each Participant receiving Restricted Stock shall be
issued a stock certificate in respect of such shares of Restricted Stock, unless the Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of shares of Restricted Stock. Such certificate shall be
registered in the name of such Participant, and shall, in addition to such legends required by applicable securities laws, bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Award, substantially in the
following form: 
 “The anticipation, alienation, attachment, sale, transfer, assignment, pledge, encumbrance or charge of the shares of
stock represented hereby are subject to the terms and conditions (including forfeiture) of the MineCo Holdings, Inc. (the “Company”) 2018 Omnibus Incentive Plan (the “Plan”) and an Agreement entered into between the registered
owner and the Company dated. Copies of such Plan and Agreement are on file at the principal office of the Company.” 

  
 13 

 (d) Custody. If stock certificates are issued in respect of shares of Restricted
Stock, the Committee may require that any stock certificates evidencing such shares be held in custody by the Company until the restrictions thereon shall have lapsed, and that, as a condition of any grant of Restricted Stock, the Participant shall
have delivered a duly signed stock power or other instruments of assignment (including a power of attorney), each endorsed in blank with a guarantee of signature if deemed necessary or appropriate by the Company, which would permit transfer to the
Company of all or a portion of the shares subject to the Restricted Stock Award in the event that such Award is forfeited in whole or part. 

8.3 Restrictions and Conditions. The shares of Restricted Stock or Restricted Stock Units awarded pursuant to the Plan
shall be subject to the following restrictions and conditions: 
 (a) Restriction Period. (i) The Participant shall not be
permitted to Transfer shares of Restricted Stock or Restricted Stock Units awarded under the Plan during the period or periods set by the Committee (the “Restriction Period”) commencing on the date of such Award, as set forth in the
applicable Restricted Stock or Restricted Stock Unit Award Agreement and such agreement shall set forth a vesting schedule and any event that would accelerate vesting of the shares of Restricted Stock or the Restricted Stock Units. Within these
limits, based on service, attainment of Performance Goals and/or such other factors or criteria as the Committee may determine in its sole discretion, the Committee may condition the grant or provide for the lapse of such restrictions in
installments in whole or in part, or may accelerate the vesting of all or any part of any Restricted Stock Award or Restricted Stock Unit Award and/or waive the deferral limitations for all or any part of any Restricted Stock Award or Restricted
Stock Unit Award. 
 (b) Rights as a Stockholder. Except as provided in Section 8.3(a) and this Section 8.3(b) or as
otherwise determined by the Committee in an Award Agreement, the Participant shall have, with respect to the shares of Restricted Stock, all of the rights of a holder of shares of Common Stock of the Company, including, without limitation, the right
to receive dividends, the right to vote such shares and, subject to and conditioned upon the full vesting of shares of Restricted Stock, the right to tender such shares. The Committee may, in its sole discretion, determine at the time of grant that
the payment of dividends shall be deferred until, and conditioned upon, the expiration of the applicable Restriction Period. 
 (c)
Termination. Unless otherwise determined by the Committee at grant or, if no rights of the Participant are reduced, thereafter, subject to the applicable provisions of the Award Agreement and the Plan, upon a Participant’s Termination
for any reason during the relevant Restriction Period, all Restricted Stock and Restricted Stock Units still subject to restriction will be forfeited in accordance with the terms and conditions established by the Committee at grant or thereafter.

 (d) Lapse of Restrictions. If and when the Restriction Period expires without a prior forfeiture of the Restricted Stock, the
certificates for such shares shall be delivered to the Participant. All legends shall be removed from said certificates at the time of delivery to the Participant, except as otherwise required by applicable law or other limitations imposed by the
Committee. 
 (e) Payment of Restricted Stock Units. The Committee may determine the form or forms (including cash, shares, other
Awards, other property or any combination thereof) in which payment of the amount owing upon settlement of any Restricted Stock Unit Awards may be made, including the ability for a Participant to elect to defer payment in settlement of Restricted
Stock Unit Awards. Participants holding Restricted Stock Units shall not have the rights of a holder of shares of Common of the Company until the applicable shares have been delivered to the Participant. Each Restricted Stock Unit shall be credited
with an amount equal to the dividends paid on a share of Common Stock between the date of grant and the date such Restricted Stock Unit is paid out to the Participant, if at all. Dividend equivalents shall vest, if at all, upon the same terms and
conditions governing the vesting of Restricted Stock Units under the Plan. Payment of the dividend equivalent shall be made at the same time as payment of the Restricted Stock Unit and shall be made without interest or other adjustment. If the
Restricted Stock Unit is forfeited, the Participant shall have no right to dividend equivalents 

  
 14 

 ARTICLE IX 

PERFORMANCE AWARDS 

9.1 Performance Awards. The Committee may grant a Performance Award to a Participant payable upon the attainment of
specific Performance Goals. If the Performance Award is payable in shares of Restricted Stock, such shares shall be transferable to the Participant only upon attainment of the relevant Performance Goal in accordance with Article VIII. If the
Performance Award is payable in cash, it may be paid upon the attainment of the relevant Performance Goals either in cash or in shares of Restricted Stock (based on the then current Fair Market Value of such shares), as determined by the Committee,
in its sole and absolute discretion. Each Performance Award shall be evidenced by an Award Agreement in such form that is not inconsistent with the Plan and that the Committee may from time to time approve.

and conditions: 
 (a) Earning of Performance Award. At the expiration of the applicable Performance Period, the Committee shall
determine the extent to which the Performance Goals are achieved and the percentage of each Performance Award that has been earned. 
 (b)
Non-Transferability. Subject to the applicable provisions of the Award Agreement and the Plan, Performance Awards may not be Transferred during the Performance Period. 

(c) Dividends. Unless otherwise determined by the Committee at the time of grant, amounts equal to dividends declared during the
Performance Period with respect to the number of shares of Common Stock covered by a Performance Award will not be paid to the Participant. 

(d) Payment. Following the Committee’s determination in accordance with Section 9.2(a), the Company shall settle Performance
Awards, in such form (including, without limitation, in shares of Common Stock or in cash) as determined by the Committee, in an amount equal to such Participant’s earned Performance Awards. 

(e) Termination. Subject to the applicable provisions of the Award Agreement and the Plan, upon a Participant’s Termination for any
reason during the Performance Period for a given Performance Award, the Performance Award in question will vest or be forfeited in accordance with the terms and conditions established by the Committee at grant. 

(f) Accelerated Vesting. Based on service, performance and/or such other factors or criteria, if any, as the Committee may determine,
the Committee may, at or after grant, accelerate the vesting of all or any part of any Performance Award. 
 ARTICLE X 

OTHER STOCK-BASED AND CASH-BASED AWARDS 

10.1 Other Stock-Based Awards. The Committee is authorized to grant to Eligible Individuals Other Stock-Based Awards that
are payable in, valued in whole or in part by reference to, or otherwise based on or related to shares of Common Stock, including but not limited to, shares of Common Stock awarded purely as a bonus and not subject to restrictions or conditions,
shares of Common Stock in payment of the amounts due under an incentive or performance plan sponsored or maintained by the Company or an Affiliate, stock equivalent units, and Awards valued by reference to book value of shares of Common Stock. Other
Stock-Based Awards may be granted either alone or in addition to or in tandem with other Awards granted under the Plan. 
 Subject to the
provisions of the Plan, the Committee shall have authority to determine the Eligible Individuals, to whom, and the time or times at which, such Awards shall be made, the number of shares of Common Stock to be awarded pursuant to such Awards, and all
other conditions of the Awards. The Committee may also provide for the grant of Common Stock under such Awards upon the completion of a specified Performance Period. The Committee may condition the grant or vesting of Other Stock-Based Awards upon
the attainment of specified Performance Goals as the Committee may determine, in its sole discretion. 

  
 15 

 10.2 Terms and Conditions. Other Stock-Based Awards made pursuant to
this Article X shall be subject to the following terms and conditions: 
 (a)
Non-Transferability. Subject to the applicable provisions of the Award Agreement and the Plan, shares of Common Stock subject to Awards made under this Article X may not be Transferred prior to the date
on which the shares are issued, or, if later, the date on which any applicable restriction, performance or deferral period lapses. 
 (b)
Dividends. Unless otherwise determined by the Committee at the time of Award, subject to the provisions of the Award Agreement and the Plan, the recipient of an Award under this Article X shall not be entitled to receive, currently or on a
deferred basis, dividends or dividend equivalents in respect of the number of shares of Common Stock covered by the Award. 
 (c)
Vesting. Any Award under this Article X and any Common Stock covered by any such Award shall vest or be forfeited to the extent so provided in the Award Agreement, as determined by the Committee, in its sole discretion.

consideration as may be required by applicable law, as it shall determine in its sole discretion. Other Cash-Based Awards may be granted subject to the satisfaction of vesting conditions or may be awarded purely as a bonus and not subject to
restrictions or conditions, and if subject to vesting conditions, the Committee may accelerate the vesting of such Awards at any time in its sole discretion. The grant of an Other Cash-Based Award shall not require a segregation of any of the
Company’s assets for satisfaction of the Company’s payment obligation thereunder. 
 ARTICLE XI 

CHANGE IN CONTROL PROVISIONS 

11.1 Benefits. In the event of a Change in Control of the Company (as defined below), and except as otherwise
provided by the Committee in an Award Agreement, a Participant’s unvested Awards shall not vest automatically and a Participant’s Awards shall be treated in accordance with one or more of the following methods as determined by the
Committee: 
 (a) Awards, whether or not then vested, shall be continued, assumed, or have new rights substituted therefor, as determined by
the Committee in a manner consistent with the requirements of Section 409A of the Code, and restrictions to which shares of Restricted Stock or any other Award granted prior to the Change in Control are subject shall not lapse upon a Change in
Control and the Restricted Stock or other Award shall, where appropriate in the sole discretion of the Committee, receive the same distribution as other Common Stock on such terms as determined by the Committee; provided that the Committee
may decide to award additional Restricted Stock or other Awards in lieu of any cash distribution. Notwithstanding anything to the contrary herein, for purposes of Incentive Stock Options, any assumed or substituted Stock Option shall comply with the
requirements of Treasury Regulation Section 1.424-1 (and any amendment thereto). 
 (b) The
Committee, in its sole discretion, may provide for the purchase of any Awards by the Company or an Affiliate for an amount of cash equal to the excess (if any) of the Change in Control Price (as defined below) of the shares of Common Stock covered
by such Awards, over the aggregate exercise price of such Awards. 

  
 16 

 
For purposes hereof, “Change in Control Price” shall mean the highest price per share of Common Stock paid in any transaction related to a Change in Control of the Company. 

(c) The Committee may, in its sole discretion, terminate all outstanding and unexercised Stock Options, Stock Appreciation Rights, or any Other
Stock-Based Award that provides for a Participant elected exercise, effective as of the date of the Change in Control, by delivering notice of termination to each Participant at least twenty (20) days prior to the date of consummation of the
Change in Control, in which case during the period from the date on which such notice of termination is delivered to the consummation of the Change in Control, each such Participant shall have the right to exercise in full all of such
Participant’s Awards that are then outstanding (without regard to any limitations on exercisability otherwise contained in the Award Agreements), but any such exercise shall be contingent on the occurrence of the Change in Control, and,
provided that, if the Change in Control does not take place within a specified period after giving such notice for any reason whatsoever, the notice and exercise pursuant thereto shall be null and void. 

(d) Notwithstanding any other provision herein to the contrary, the Committee may, in its sole discretion, provide for accelerated vesting or
lapse of restrictions, of an Award at any time. 
 11.2 Change in Control. Unless otherwise determined by the Committee
in the applicable Award Agreement or other written agreement with a Participant approved by the Committee, a “Change in Control” shall be deemed to occur if: 

(a) any “person,” as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, any trustee or other
fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of Common Stock of the Company),
becoming the beneficial owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 50% or more of the combined voting power of the Company’s
then outstanding securities; 
 (b) during any period of two consecutive years, individuals who at the beginning of such period constitute
the Board, and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in paragraph (a), (c), or (d) of this Section 11.2 or a director whose
initial assumption of office occurs as a result of either an actual or threatened election contest (as such term is used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a person other than the Board) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the two-year period or whose election or nomination for election was previously
so approved, cease for any reason to constitute at least a majority of the Board; 
 (c) a merger or consolidation of the Company or a
Subsidiary of the Company with any other corporation, other than a merger or consolidation which would result in (i) the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the Company or the ultimate Parent company of the Company outstanding immediately after such
merger or consolidation in substantially the same proportions of ownership as immediately prior to such merger or consolidation and (ii) the members of the Board immediately prior to such merger or consolidation continuing to constitute a
majority of the board of directors of the Company or the ultimate Parent company of the Company outstanding immediately after such merger or consolidation; provided, however, that a merger or consolidation effected to implement a
recapitalization of the Company (or similar transaction) in which no person (other than those covered by the exceptions in Section 11.2(a)) acquires more than 50% of the combined voting power of the Company’s then outstanding securities
shall not constitute a Change in Control of the Company; or 
 (d) a complete liquidation or dissolution of the Company or the consummation
of a sale or disposition by the Company of all or substantially all of the Company’s assets other than the sale or disposition of all or substantially all of the assets of the Company to a person or persons who beneficially own, directly or
indirectly, 50% or more of the combined voting power of the outstanding voting securities of the Company at the time of the sale. 

  
 17 

 Notwithstanding the foregoing, with respect to any Award that is characterized as
“nonqualified deferred compensation” within the meaning of Section 409A of the Code, an event shall not be considered to be a Change in Control under the Plan for purposes of payment of such Award unless such event is also a
“change in ownership,” a “change in effective control” or a “change in the ownership of a substantial portion of the assets” of the Company within the meaning of Section 409A of the Code.

include any legend that the Committee deems appropriate to reflect any restrictions on Transfer. All certificates for shares of Common Stock delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the
Committee may deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any stock exchange upon which the Common Stock is then listed or any national securities exchange system upon whose system

until such shares are so listed, and the right to exercise any Option or other Award with respect to such shares shall be suspended until such listing has been effected.

other Award is or may in the circumstances be unlawful or result in the imposition of excise taxes on the Company under the statutes, rules or regulations of any applicable jurisdiction, the Company shall have no obligation to make such sale or
delivery, or to make any application or to effect or to maintain any qualification or registration under the Securities Act or otherwise, with respect to shares of Common Stock or Awards, and the right to exercise any Option or other Award shall be
suspended until, in the opinion of said counsel, such sale or delivery shall be lawful or will not result in the imposition of excise taxes on the Company. 

(c) Upon termination of any period of suspension under this Section 14.6, any Award affected by such suspension which shall not then have
expired or terminated shall be reinstated as to all shares available before such suspension and as to shares which would otherwise have become available during the period of such suspension, but no such suspension shall extend the term of any Award.

14.13 Death/Disability. The Committee may in its discretion require the transferee of a Participant to supply it with
written notice of the Participant’s death or Disability and to supply it with a copy of the will (in the case of the Participant’s death) or such other evidence as the Committee deems necessary to establish the validity of the transfer of

	6.	 Employee Benefits. Effective as of your Start Date, you will be eligible to participate in employee

	7.	 Severance: In the event of a termination of your employment by the Company without Cause (as defined

benefit equal to three (3) months of your Base Salary (the “Severance Amount”). The Accrued Obligations will be paid in a single lump sum within 10 business days following the date of termination, and the Severance Amount will
be paid in equal installments over a period of three (3) months in accordance with the Company’s regular payroll practices. Receipt of the Severance Amount is conditioned upon your execution and
non-revocation of a general release of claims in a form provided by the Company and your continued compliance with the Employee Covenants Agreement (defined below). Payment of the Severance Amounts will begin
on the first regularly scheduled payroll date following the 45th day after such termination and the first payment shall include any amounts otherwise due prior thereto. 

“Cause” shall mean (i) your continued or willful failure to substantially perform the duties and obligations of your
position with the Company (other than any such failure resulting from your total and permanent disability as defined in Section 22(e)(3) of the Internal Revenue Code of 1986, as amended (the “Code”)), including the disregard of
written directives from the Chief Executive Officer, or your negligence in connection with the performance of such duties, and the failure in either such instance of you to (if capable 

  
 1 

 
of being cured) cure such failure, refusal or negligence within 10 days after the receipt by you from the Company of written notice of such failure, refusal or negligence; (ii) the knowing
and material violation by you of any Company policy, including any policy related to workplace conduct and behavior, sexual harassment or discrimination; (iii) the commission by you of any act of fraud, personal dishonesty, misappropriation,

business of the Company which violation was or is reasonably likely to be injurious to the Company; (v) your indictment for, conviction of, or entry of plea of nolo contendere or guilty to, a felony under the laws of the United States or any
State; (vi) the commission by you of a willful act of dishonesty or misrepresentation in the course of your duties which injures the Company or any customer, client, agent, shareholder or employee of the Company, or that was intended to result

relevant facts and circumstances, that the Company could have terminated your employment for Cause on the basis of acts or omissions that occurred at or prior to such resignation or termination. 

 

	8.	 Restrictive Covenants. You will, as a condition to this offer, be required to execute the Company’s
standard Proprietary Information and Inventions Agreement attached hereto as Exhibit B (the “Employee Covenants Agreement”).

comply with or be exempt from Section 409A of Code, and the regulations and guidance promulgated thereunder (collectively “Section 409A”), whether pursuant to the short-term deferral exception or otherwise,
and, accordingly, to the maximum extent permitted, this Letter Agreement shall be interpreted to be exempt from Section 409A. For purposes of Section 409A, your right to receive any installment payments pursuant to this Letter Agreement
shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Letter Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty
(30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company. If you are deemed on the date of termination to be a “specified employee”
within the meaning of that term under Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered nonqualified deferred compensation under Section 409A payable on account of a “separation
from service,” such payment or benefit shall be made or provided at the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from service,” and (ii) the date
of your death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this provision (whether they would have otherwise been payable in a single sum or in installments in the
absence of such delay) shall be paid or reimbursed on the first business day following the expiration of the Delay Period to you in a lump sum, and any remaining payments and benefits due under this Letter Agreement shall be paid or provided in
accordance with the normal payment dates specified for them herein. 

 This Letter Agreement constitutes the entire agreement and
understanding of the parties with respect to your employment and the subject matter herein and supersedes all prior agreements, arrangements and understandings, whether written or oral, between the parties. There are no restrictions, agreements,
promises, warranties, covenants or undertakings between the parties with respect to the subject matter herein other than those expressly set forth herein. You acknowledge and agree that you are not relying on any representations or promises by any
representative of the Company concerning the meaning of any aspect of this Letter Agreement. This Letter Agreement may not be altered or modified other than in a writing signed by you and an authorized representative of the Company.
