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

Shares. (a) 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 under the
Plan shall not exceed 6,300,000 shares (the “Share Authorization”). The shares may be either authorized and unissued Common Stock or Common Stock held in or acquired for the treasury of the Company or both. The full number of Stock
Appreciation Rights granted that are to be settled in Common Stock shall be counted against the number of shares of Common Stock available for award under the Plan, regardless of the number of shares of Common Stock actually issued upon settlement
of such Stock Appreciation Rights. If any Option, Stock Appreciation Right or Other Stock-Based Award granted under the Plan expires, terminates or is canceled for any reason without having been exercised in full, the number of shares of Common
Stock underlying any unexercised Award shall again be available for the purpose of Awards under the Plan. If any shares of Restricted Stock, Performance Awards or Other Stock-Based Awards denominated in shares of Common Stock awarded under the Plan
to a Participant are forfeited for any reason, the number of forfeited shares of Restricted Stock, Performance Awards or Other Stock-Based Awards denominated in shares of Common Stock shall again be available for purposes of Awards under the Plan.
If a Tandem Stock Appreciation Right or a Limited Stock Appreciation Right is granted in tandem with an Option, such grant shall only apply once against the maximum number of shares of Common Stock which may be issued under the Plan. Any Award under
the Plan settled in cash shall not be counted against the foregoing maximum share limitations. Any shares of Common Stock tendered or withheld to satisfy tax withholding obligations on an Award issued under the Plan, shares of Common Stock tendered
or withheld to pay the exercise price of an Award under the Plan, and shares of Common Stock repurchased on the open market with the proceeds of an Option exercise will no longer be eligible to be again available for grant under this Plan. 

(b) Limit on Full Value Awards. To the extent that a share of Common Stock is issued pursuant to the grant or exercise of a Full Value
Award, it shall reduce the Share Authorization by 1.35 shares of Common Stock; and, to the extent that a share of Common Stock is issued pursuant to the grant or exercise of an Award other than a Full Value Award, it shall reduce the Share
Authorization by one (1) share of Common Stock. 
 (c) Individual Participant Limitations. To the extent required by
Section 162(m) of the Code for Awards under the Plan to qualify as “performance-based compensation,” the following individual Participant limitations shall apply: 

(i) The maximum number of shares of Common Stock subject to any Award of Stock Options, or Stock Appreciation Rights, or shares of Restricted
Stock, or Other 

  
 10 








 
Stock-Based Awards for which the grant of such Award or the lapse of the relevant Restriction Period is subject to the attainment of Performance Goals in accordance with Section 8.3(a)(ii)
which may be granted under the Plan during any fiscal year of the Company to any Participant shall be one million five hundred thousand (1,500,000) shares per type of Award (which shall be subject to any further increase or decrease pursuant to
Section 4.2), provided that the maximum number of shares of Common Stock for all types of Awards does not exceed one million five hundred thousand (1,500,000) shares (which shall be subject to any further increase or decrease pursuant to
Section 4.2) during any fiscal year of the Company. If a Tandem Stock Appreciation Right is granted or a Limited Stock Appreciation Right is granted in tandem with a Stock Option, it shall apply against the Participant’s individual share
limitations for both Stock Appreciation Rights and Stock Options. 
 (ii) There are no annual individual share limitations applicable to
Participants on Restricted Stock or Other Stock-Based Awards for which the grant, vesting or payment (as applicable) of any such Award is not subject to the attainment of Performance Goals. 

(iii) The maximum number of shares of Common Stock subject to any Performance Award which may be granted under the Plan during any fiscal year
of the Company to any Participant shall be one million five hundred thousand (1,500,000) shares (which shall be subject to any further increase or decrease pursuant to Section 4.2) with respect to any fiscal year of the Company. 

(iv) The maximum value of a cash payment made under a Performance Award which may be granted under the Plan with respect to any fiscal year of
the Company to any Participant shall be seven million five hundred thousand dollars ($7,500,000). 
 (v) The individual Participant
limitations set forth in this Section 4.1(c) (other than Section 4.1(c)(iii)) shall be cumulative; that is, to the extent that shares of Common Stock for which Awards are permitted to be granted to a Participant during a fiscal year are
not covered by an Award to such Participant in a fiscal year, the number of shares of Common Stock available for Awards to such Participant shall automatically increase in the subsequent fiscal years during the term of the Plan until used. 

(d) Annual Non-Employee Director Award Limitation. The aggregate grant date fair value (computed as of the date of grant in accordance
with applicable financial accounting rules) of all Awards granted under the Plan to any individual Non-Employee Director in any fiscal year of the Company (excluding Awards made pursuant to deferred compensation arrangements in lieu of all or a
portion of cash retainers and any stock dividends payable in respect of outstanding Awards) shall not exceed $500,000.

Changes.

enlargement of benefits or potential benefits intended to be made available under the Plan (a “Section 4.2 Event”), the Committee shall equitably adjust (i) the number of shares of Common Stock or other securities of the
Company (or number and kind of other securities or property) with respect to which Awards may be granted under the Plan, (ii) the maximum share limitation applicable to each type of Award that may be granted to any individual participant in any
calendar year, (iii) the number of shares of Common Stock or other securities of the Company (or number and kind of other securities or property) subject to outstanding Awards, and (iv) the exercise price with respect to any Stock Option
or any Stock Appreciation Right. Any such adjustment determined by the Committee shall be final, binding and conclusive on the Company and all Participants and their respective heirs, executors, administrators, successors and permitted assigns. If
the Company enters into or is involved in any merger, reorganization, Change in Control or other business combination with any person or entity (a “Merger Event”), the Committee may, prior to such Merger Event and effective upon
such Merger Event, take such action as it deems appropriate, including, but not limited to, replacing Awards with substitute Awards in respect of the shares, other securities or other property of the surviving corporation or any affiliate of the
surviving corporation on such terms and conditions, as to the number of shares, pricing and otherwise, which shall substantially preserve the value, rights and benefits of any affected Awards granted hereunder as of the date of the consummation of
the Merger Event. Upon receipt by any affected Participant of any such substitute Award (or payment) as a result of any such Merger Event, such Participant’s affected Awards for which such substitute Awards (or payment) were received shall be
thereupon cancelled without the need for obtaining the consent of any such affected Participant. In addition, subject to Section 4.2(d), if there shall occur any change in the capital structure or the business of the Company that is not a
Section 4.2 Event or Merger Event (an “Other Extraordinary Event”), then the Committee, in its sole discretion, may adjust any Award and make such other adjustments to the Plan. Except as expressly provided in this
Section 4.2 or in the applicable Award Agreement, a Participant shall have no rights by reason of any Section 4.2 Event, Merger Event, or any Other Extraordinary Event. 

(c) Fractional shares of Common Stock resulting from any adjustment in Awards pursuant to Section 4.2(a) or 4.2(b) shall be aggregated
until, and eliminated at, the time of exercise 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 made 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. 

  
 12 








 (d) In the event of a Merger Event in which the Company is not the surviving entity or in the
event of any transaction that results in the acquisition of substantially all of the Company’s outstanding Common Stock by a single person or entity or by a group of persons and/or entities acting in concert, or in the event of the sale or
transfer of all or substantially all of the Company’s assets (all of the foregoing being referred to as an “Acquisition Event”), then the Committee may, in its sole discretion, terminate all outstanding and unexercised Stock
Options, Stock Appreciation Rights, or any Other Stock-Based Awards that provide for a Participant elected exercise, effective as of the date of the Acquisition Event, by delivering notice of termination to each Participant at least 10 days prior to
the date of consummation of the Acquisition Event, in which case during the period from the date on which such notice of termination is delivered to the consummation of the Acquisition Event, each such Participant shall have the right to exercise in
full all of his or her Awards that are then outstanding and vested as of such exercised date, but any such exercise may be indicated as contingent on the occurrence of the Acquisition Event, and, provided that, if the Acquisition Event does not take
place within a specified period after giving such notice for any reason whatsoever, any such notice and contingent exercise pursuant thereto shall be null and void. 

If an Acquisition Event occurs but the Committee does not terminate the outstanding Awards pursuant to this Section 4.2(d), then the
provisions of Section 4.2(b) and Article XI shall apply. 
 4.3 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. 

ARTICLE V 
 ELIGIBILITY

 5.1 General Eligibility. All current and prospective Eligible Individuals are eligible to be granted Awards.
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. 

5.3 General Requirement. The vesting and exercise of Awards granted to a prospective Eligible Individual are conditioned upon
such individual actually becoming an Eligible Employee, Consultant or Non-Employee Director, respectively. 
 5.4 Minimum Vesting
Requirements. The minimum vesting period for any Award shall be one (1) year from the date of grant. 

  
 13 








 ARTICLE VI 

STOCK OPTIONS 
 6.1
Options. Stock Options may be granted alone or in addition to other Awards granted under the Plan. 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 an Incentive Stock Option shall be at least equal to 100% (or, in the case of a Ten Percent Stockholder, 110%) of the Fair Market Value of the Common Stock at the time of grant. To the
extent that a Stock Option is granted with an exercise price that is less than 100% of the Fair Market Value of the Common Stock at the time of grant, such Stock Option will be intended to comply with the requirements of Section 409A of the
Code, and the Committee shall take such requirements into account when approving any such 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. 
 (c) Exercisability. Unless otherwise provided by the Committee in accordance with the
provisions of this Section 6.4, and subject to Section 5.4, 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). Unless otherwise determined by the Committee at the time of grant, the Option agreement shall provide that (i) in the event that the Participant engages in Detrimental Activity prior to any exercise of the


  
 14 








 
Stock Option (whether vested or unvested), all Stock Options held by the Participant shall thereupon terminate and expire, (ii) as a condition of the exercise of a Stock Option, the
Participant shall be required to certify (or shall be deemed to have certified) at the time of exercise in a manner acceptable to the Company that the Participant is in compliance with the terms and conditions of the Plan and that the Participant
has not engaged in, and does not intend to engage in, any Detrimental Activity, and (iii) in the event that the Participant engages in Detrimental Activity during the one-year period commencing on the date that the Stock Option is exercised or
becomes vested, the Company shall be entitled to recover from the Participant at any time within one year after such exercise or vesting, and the Participant shall pay over to the Company, an amount equal to any gain realized as a result of the
exercise (whether at the time of exercise or thereafter). 
 (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 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, having the Company withhold shares of Common
Stock issuable upon exercise of the Stock Options 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 therefore, as provided herein, has been made or provided for. 
 (e) Non-Transferability of
Options. No Stock Option shall be Transferable by the Participant otherwise 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 otherwise than by will or by the laws of descent and distribution and (ii) remains subject to the terms of this 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 this Plan and the applicable Award Agreement.

 (f) 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


  
 15 








 
be exercised by the Participant at any time within a period of one year from the date of such Termination (or in the case of death, by the legal representative of the Participant’s estate),
but in no event beyond the expiration of the stated term of such Stock Options; provided, however, that, in the case of a Termination due to 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 year from the date of such death, but in no event beyond the expiration of the stated term of such Stock Options.

 (g) Involuntary Termination Without 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 is by involuntary termination without Cause, 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 90 days from the date of such Termination, but in no event beyond the expiration of the stated term of such Stock Options. 

(h) Voluntary Termination. 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(i)(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 90 days from the date of such Termination, but in no event beyond the expiration of the stated term of such Stock Options. 

(i) 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(h)) 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. 

(j) 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. 

(k) 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 this 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 this 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 this Plan accordingly, without the necessity of obtaining the approval of the
stockholders of the Company. 

  
 16 








 (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 his or her 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 (up to the extent not theretofore exercised) and authorize the granting of new Stock Options in substitution therefor (to the extent not theretofore exercised). Notwithstanding the
foregoing, an outstanding Option may not be modified to reduce the exercise price thereof nor may a new Option at a lower price be substituted for a surrendered Option (other than adjustments or substitutions in accordance with Section 4.2) nor
may any cash payment be made for a surrendered Option, unless such action is approved by the stockholders of the Company. 
 (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) 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 Tandem Stock Appreciation Rights. Stock Appreciation Rights may be granted in conjunction with all or part of any Stock
Option (a “Reference Stock Option”) granted under the Plan (“Tandem Stock Appreciation Rights”). In the case of a Non-Qualified Stock Option, such rights may be granted either at or after the time of the grant of
such Reference Stock Option. In the case of an Incentive Stock Option, such rights may be granted only at the time of the grant of such Reference Stock Option. 

  
 17 








 7.2 Terms and Conditions of Tandem Stock Appreciation Rights. Tandem 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 Tandem Stock Appreciation Right shall be determined by the
Committee at the time of grant. To the extent that a Stock Appreciation Right is granted with an exercise price that is less than 100% of the Fair Market Value of the Common Stock at the time of grant, such Stock Appreciation Right will be intended
to comply with the requirements of Section 409A of the Code, and the Committee shall take such requirements into account when approving any such grant. 

(b) Term. A Tandem Stock Appreciation Right or applicable portion thereof granted with respect to a Reference Stock Option shall
terminate and no longer be exercisable upon the termination or exercise of the Reference Stock Option, except that, unless otherwise determined by the Committee, in its sole discretion, at the time of grant, a Tandem Stock Appreciation Right granted
with respect to less than the full number of shares covered by the Reference Stock Option shall not be reduced until and then only to the extent that the exercise or termination of the Reference Stock Option causes the number of shares covered by
the Tandem Stock Appreciation Right to exceed the number of shares remaining available and unexercised under the Reference Stock Option. 

(c) Exercisability. Tandem Stock Appreciation Rights shall be exercisable only at such time or times and to the extent that the
Reference Stock Options to which they relate shall be exercisable in accordance with the provisions of Article VI, and shall be subject to the provisions of Section 6.4(c). 

(d) Method of Exercise. A Tandem Stock Appreciation Right may be exercised by the Participant by surrendering the applicable portion of
the Reference Stock Option. Upon such exercise and surrender, the Participant shall be entitled to receive an amount determined in the manner prescribed in this Section 7.2. Stock Options which have been so surrendered, in whole or in part,
shall no longer be exercisable to the extent that the related Tandem Stock Appreciation Rights have been exercised. 
 (e) Payment.
Upon the exercise of a Tandem Stock Appreciation Right, a Participant shall be entitled to receive 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 over the Option exercise price per share specified in the Reference Stock Option agreement multiplied by the number of shares of Common Stock in respect of which the Tandem Stock Appreciation Right
shall have been exercised, with the Committee having the right to determine the form of payment. 
 (f) Deemed Exercise of Reference Stock
Option. Upon the exercise of a Tandem Stock Appreciation Right, the Reference Stock Option or part thereof to which such Stock Appreciation Right is related shall be deemed to have been exercised for the purpose of the limitation set forth in
Article IV of the Plan on the number of shares of Common Stock to be issued under the Plan. 
 (g) Non-Transferability. Tandem Stock
Appreciation Rights shall be Transferable only when and to the extent that the underlying Stock Option would be Transferable under Section 6.4(e) of the Plan. 

  
 18 








 7.3 Non-Tandem Stock Appreciation Rights. Non-Tandem Stock Appreciation Rights may
also be granted without reference to any Stock Options granted under the Plan. 
 7.4 Terms and Conditions of Non-Tandem Stock
Appreciation Rights. Non-Tandem 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 Non-Tandem Stock Appreciation Right shall
be determined by the Committee at the time of grant, provided that the per share exercise price of a Non-Tandem 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 Non-Tandem 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 7.4, and subject to Section 5.4, Non-Tandem 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). 
 Unless otherwise determined by the Committee at grant, the Award Agreement shall provide that (i) in the event
that the Participant engages in Detrimental Activity prior to any exercise of the Non-Tandem Stock Appreciation Right, all Non-Tandem Stock Appreciation Rights held by the Participant shall thereupon terminate and expire, (ii) as a condition of
the exercise of a Non-Tandem Stock Appreciation Right, the Participant shall be required to certify (or shall be deemed to have certified) at the time of exercise in a manner acceptable to the Company that the Participant is in compliance with the
terms and conditions of the Plan and that the Participant has not engaged in, and does not intend to engage in, any Detrimental Activity, and (iii) in the event that the Participant engages in Detrimental Activity during the one-year period
commencing on the date the Non-Tandem Stock Appreciation Right is exercised or becomes vested, the Company shall be entitled to recover from the Participant at any time within one year after such exercise or vesting, and the Participant shall pay
over to the Company, an amount equal to any gain realized as a result of the exercise (whether at the time of exercise or thereafter). 
 (d)
Method of Exercise. Subject to whatever installment exercise and waiting period provisions apply under Section 7.4(c), Non-Tandem 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 Non-Tandem Stock Appreciation Rights to be exercised. 

  
 19 








 (e) Payment. Upon the exercise of a Non-Tandem 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, Non-Tandem 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(j). 

(g) Non-Transferability. No Non-Tandem Stock Appreciation Rights shall be Transferable by the Participant otherwise 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. 

7.5 Limited Stock Appreciation Rights. The Committee may, in its sole discretion, grant Tandem and Non-Tandem Stock Appreciation
Rights either as a general Stock Appreciation Right or as a Limited Stock Appreciation Right. Limited Stock Appreciation Rights may be exercised only upon the occurrence of a Change in Control or such other event as the Committee may, in its sole
discretion, designate at the time of grant or thereafter. Upon the exercise of Limited Stock Appreciation Rights, except as otherwise provided in an Award Agreement, the Participant shall receive in cash and/or Common Stock, as determined by the
Committee, an amount equal to the amount (i) set forth in Section 7.2(e) with respect to Tandem Stock Appreciation Rights, or (ii) set forth in Section 7.4(e) with respect to Non-Tandem Stock Appreciation Rights. 

7.6 No Repricings or Cash Buyouts of Stock Appreciation Rights. Notwithstanding the foregoing, an outstanding Stock Appreciation
Right may not be modified to reduce the exercise price thereof nor may a new Stock Appreciation Right at a lower price be substituted for a surrendered Stock Appreciation Right (other than adjustments or substitutions in accordance with
Section 4.2) nor may any cash payment be made for a surrendered Stock Appreciation Right, unless such action is approved by the stockholders of the Company. 

ARTICLE VIII 
 RESTRICTED
STOCK 
 8.1 Awards of Restricted Stock. Shares of Restricted Stock 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 (subject to Section 5.4) and rights to acceleration thereof, and all other terms and conditions of the
Awards. 

  
 20 








 Unless otherwise determined by the Committee at grant, each Award of Restricted Stock shall
provide that in the event that the Participant engages in Detrimental Activity prior to, or during the one-year period after, any vesting of Restricted Stock, the Committee may direct that all unvested Restricted Stock shall be immediately forfeited
to the Company and that the Participant shall pay over to the Company an amount equal to the Fair Market Value at the time of vesting of any Restricted Stock which had vested in the period referred to above. 

The Committee may condition the grant or vesting of Restricted Stock upon the attainment of specified performance targets (including, the
Performance Goals) or such other factor as the Committee may determine in its sole discretion, including to comply with the requirements of Section 162(m) of the Code. 

8.2 Awards and Certificates. Eligible Individuals selected to receive Restricted Stock 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 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 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 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 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 Amended and Restated U.S. Silica Holdings, Inc. (the “Company”) 2011 Incentive Compensation 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.” 
 (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 

  
 21 








 
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 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 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 Restricted Stock Award Agreement and such agreement
shall set forth a vesting schedule and any event that would accelerate vesting of the shares of Restricted Stock. Within these limits, based on service, attainment of Performance Goals pursuant to Section 8.3(a)(ii) 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 and/or waive the deferral limitations for all or any part of any Restricted Stock Award. 
 (ii) If the grant of
shares of Restricted Stock or the lapse of restrictions is based on the attainment of Performance Goals, the Committee shall establish the objective Performance Goals and the applicable vesting percentage of the Restricted Stock applicable to each
Participant or class of Participants in writing prior to the beginning of the applicable fiscal year or at such later date as otherwise determined by the Committee and while the outcome of the Performance Goals are substantially uncertain. Such
Performance Goals may incorporate provisions for disregarding (or adjusting for) changes in accounting methods, corporate transactions (including, without limitation, dispositions and acquisitions) and other similar type events or circumstances.
With regard to a Restricted Stock Award that is intended to comply with Section 162(m) of the Code, to the extent that any such provision would create impermissible discretion under Section 162(m) of the Code or otherwise violate
Section 162(m) of the Code, such provision shall be of no force or effect. 
 (b) Rights as a Stockholder. Except as provided in
Section 8.3(a) and this Section 8.3(b) and as otherwise determined by the Committee, 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 vote such shares, subject to and conditioned upon the full vesting of shares of Restricted Stock, the right to tender such shares, and the right to receive all dividends and other distributions paid with
respect to the Restricted Stock, provided that such dividends or other distributions will be subject to the same vesting requirements as the underlying Restricted Stock and shall be paid at the time the Restricted Stock becomes vested. If dividends
or distributions are paid in shares of Common Stock, such shares shall be deposited with the Company and shall be subject to the same restrictions on transferability and forfeitability as the Restricted Stock with respect to which they were paid.
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. 

  
 22 








 (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 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, if any, shall be delivered to the Participant, unless the Committee elects to use another
system, such as book entries by the transfer agent. 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. 

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. The Committee may grant Performance Awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code, as well as Performance Awards that are not intended to
qualify as “performance-based compensation” under Section 162(m) of the Code. 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. 
 Unless otherwise determined by the Committee at grant, each Performance Award shall provide that in the event the
Participant engages in Detrimental Activity prior to, or during the one-year period after, any vesting of the Performance Award, the Committee may direct (at any time within one year thereafter) that all of the unvested portion of the Performance
Award shall be immediately forfeited to the Company and that the Participant shall pay over to the Company an amount equal to any gain that the Participant realized from any Performance Award that had vested in the period referred to above. 

With respect to Performance Awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the
Code, the Committee shall condition the right to payment of any Performance Award upon the attainment of objective Performance Goals established pursuant to Section 9.2(c). 

9.2 Terms and Conditions. Performance Awards awarded pursuant to this Article IX shall be subject to the following terms 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 established pursuant to Section 9.2(c) are achieved and the percentage of each Performance Award that has been earned. 

  
 23 








 (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) Objective Performance Goals, Formulae or
Standards. With respect to Performance Awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall establish the objective Performance Goals for the earning of
Performance Awards based on a Performance Period applicable to each Participant or class of Participants in writing prior to the beginning of the applicable Performance Period or at such later date as permitted under Section 162(m) of the Code
and while the outcome of the Performance Goals are substantially uncertain. Such Performance Goals may incorporate, if and only to the extent permitted under Section 162(m) of the Code, provisions for disregarding (or adjusting for) changes in
accounting methods, corporate transactions (including, without limitation, dispositions and acquisitions) and other similar type events or circumstances. To the extent that any such provision would create impermissible discretion under
Section 162(m) of the Code or otherwise violate Section 162(m) of the Code, such provision shall be of no force or effect, with respect to Performance Awards that are intended to qualify as “performance-based compensation” under
Section 162(m) of the Code. 
 (d) 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. 

(e) 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. Notwithstanding the foregoing, the Committee may, in
its sole discretion, award an amount less than the earned Performance Awards and/or subject the payment of all or part of any Performance Award to additional vesting, forfeiture and deferral conditions as it deems appropriate. 

(f) 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. 

(g) 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 

  
 24 








 
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, restricted stock 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; provided that to the extent that such Other Stock-Based Awards are intended to comply with Section 162(m) of the Code, the Committee shall
establish the objective Performance Goals for the grant or vesting of such Other Stock-Based Awards based on a Performance Period applicable to each Participant or class of Participants in writing prior to the beginning of the applicable Performance
Period or at such later date as permitted under Section 162(m) of the Code and while the outcome of the Performance Goals are substantially uncertain. Such Performance Goals may incorporate, if and only to the extent permitted under
Section 162(m) of the Code, provisions for disregarding (or adjusting for) changes in accounting methods, corporate transactions (including, without limitation, dispositions and acquisitions) and other similar type events or circumstances. To
the extent that any such provision would create impermissible discretion under Section 162(m) of the Code or otherwise violate Section 162(m) of the Code, such provision shall be of no force or effect, with respect to Performance Awards
that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code. 
 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 with respect to the number of shares of Common Stock covered by the Award, as determined at the time of the Award by the Committee, in its sole discretion. 

(c) Vesting. Subject to Section 5.4, 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. 

  
 25 








 (d) Price. Common Stock issued on a bonus basis under this Article X may be issued for no
cash consideration. Common Stock purchased pursuant to a purchase right awarded under this Article X shall be priced, as determined by the Committee in its sole discretion. 

10.3 Other Cash-Based Awards. The Committee may from time to time grant Other Cash-Based Awards to Eligible Individuals in such
amounts, on such terms and conditions, and for such consideration, including no consideration or such minimum 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. 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. 

10.4 Detrimental Activity. Unless otherwise determined by the Committee at grant, the Award Agreement shall provide that
(i) in the event that the Participant engages in Detrimental Activity prior to any exercise, distribution or settlement of any Other Stock-Based Award and/or Other Cash-Based Award, such Other Stock-Based Awards and/or Other Cash-Based Awards
held by the Participant shall thereupon terminate and expire, (ii) as a condition of the exercise, distribution or settlement of an Other Stock-Based Award and/or Other Cash-Based Award, the Participant shall be required to certify (or shall be
deemed to have certified) at the time of exercise in a manner acceptable to the Company that the Participant is in compliance with the terms and conditions of the Plan and that the Participant has not engaged in, and does not intend to engage in,
any Detrimental Activity, and (iii) in the event that the Participant engages in Detrimental Activity during the one-year period commencing on the date of exercise, distribution, or settlement of an Other Stock-Based Award and/or Other
Cash-Based Award, the Company shall be entitled to recover from the Participant at any time within one year after such exercise, settlement, or distribution, and the Participant shall pay over to the Company, an amount equal to any gain realized as
a result of the exercise, distribution or settlement (whether at the time of exercise, distribution or settlement or thereafter). 

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 and a Participant’s Awards shall be treated in accordance with one of the following methods as determined by the Committee: 

(a) Awards, whether or not then vested, shall be continued, assumed, have new rights substituted therefor or be treated in accordance with
Section 4.2(d) hereof in a manner consistent with the requirements of Section 409A of the Code, as determined by the Committee, 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 

  
 26 








 
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.
For purposes of this Section 11.1, “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) 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 in connection with a Change of Control of the Company. 
 11.2 Change in Control. Unless
otherwise determined by the Committee in the applicable Award Agreement or other written agreement 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 with any other corporation, other than a merger or
consolidation which would result in 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 such surviving entity 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 

  
 27 








 (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. 
 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
any 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. 
 ARTICLE XII 

TERMINATION OR AMENDMENT OF PLAN 

12.1 Termination or Amendment. Notwithstanding any other provision of the Plan, the Board may at any time, and from time to
time, amend, in whole or in part, any or all of the provisions of the Plan (including any amendment deemed necessary to ensure that the Company may comply with any regulatory requirement referred to in Article XIV or Section 409A of the Code),
or suspend or terminate it entirely, retroactively or otherwise; provided, however, that, unless otherwise required by law or specifically provided herein, the rights of a Participant with respect to Awards granted prior to such amendment,
suspension or termination, may not be impaired without the consent of such Participant and, provided further, that without the approval of the holders of the Company’s Common Stock entitled to vote in accordance with applicable law, no
amendment may be made that would (i) increase the aggregate number of shares of Common Stock that may be issued under the Plan (except by operation of Section 4.2); (ii) increase the maximum individual Participant limitations for a
fiscal year under Section 4.1(c) (except by operation of Section 4.2); (iii) change the classification of individuals eligible to receive Awards under the Plan; (iv) decrease the minimum option price of any Stock Option or Stock
Appreciation Right; (v) extend the maximum option period under Section 6.4; (vi) alter the Performance Goals for Restricted Stock, Performance Awards or Other Stock-Based Awards as set forth in Exhibit A hereto;
(vii) award any Stock Option or Stock Appreciation Right in replacement of a canceled Stock Option or Stock Appreciation Right with a higher exercise price than the replacement award, except in accordance with Section 6.4(l); or
(viii) require stockholder approval in order for the Plan to continue to comply with the applicable provisions of Section 162(m) of the Code or, to the extent applicable to Incentive Stock Options, Section 422 of the Code. In no event
may the Plan be amended without the approval of the stockholders of the Company in accordance with the applicable laws of the State of Delaware to increase the aggregate number of shares of Common Stock that may be issued under the Plan, decrease
the minimum exercise price of any Award, or to make any other amendment that would require stockholder approval under Financial Industry Regulatory Authority (FINRA) rules and regulations or the rules of any exchange or system on which the
Company’s securities are listed or traded at the request of the Company. Notwithstanding anything herein to the contrary, the Board may amend the Plan or any Award Agreement at any time without a Participant’s consent to comply with
applicable law including Section 409A of the Code. 

  
 28 








 The Committee may amend the terms of any Award theretofore granted, prospectively or
retroactively, but, subject to Article IV or as otherwise specifically provided herein, no such amendment or other action by the Committee shall impair the rights of any holder without the holder’s consent. 

ARTICLE XIII 
 UNFUNDED
STATUS OF PLAN 
 The Plan is intended to constitute an “unfunded” plan for incentive and deferred compensation. With respect
to any payment as to which a Participant has a fixed and vested interest but which are not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any right that is greater than those of a general unsecured
creditor of the Company. 
 ARTICLE XIV 

GENERAL PROVISIONS 

14.1 Legend. The Committee may require each person receiving shares of Common Stock pursuant to a Stock Option or other Award
under the Plan to represent to and agree with the Company in writing that the Participant is acquiring the shares without a view to distribution thereof. In addition to any legend required by the Plan, the certificates for such shares may 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 the Common Stock
is then quoted, any applicable federal or state securities law, and any applicable corporate law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

14.2 Other Plans. Nothing contained in the Plan shall prevent the Board from adopting other or additional compensation
arrangements, subject to stockholder approval if such approval is required, and such arrangements may be either generally applicable or applicable only in specific cases. 

14.3 No Right to Employment/Directorship/Consultancy. Neither the Plan nor the grant of any Option or other Award hereunder
shall give any Participant or other employee, Consultant or Non-Employee Director any right with respect to continuance of employment, consultancy or directorship by the Company or any Affiliate, nor shall there be a limitation in any way on the
right of the Company or any Affiliate by which an employee is employed or a Consultant or Non-Employee Director is retained to terminate his or her employment, consultancy or directorship at any time. 

14.4 Withholding of Taxes. The Company shall have the right to deduct from any payment to be made pursuant to the Plan, or to
otherwise require, prior to the issuance or delivery 

  
 29 








 
of shares of Common Stock or the payment of any cash hereunder, payment by the Participant of, any federal, state or local taxes required by law to be withheld. Upon the vesting of Restricted
Stock (or other Award that is taxable upon vesting), or upon making an election under Section 83(b) of the Code, a Participant shall pay all required withholding to the Company. Any minimum statutorily required withholding obligation with
regard to any Participant may be satisfied, subject to the consent of the Committee, by reducing the number of shares of Common Stock otherwise deliverable or by delivering shares of Common Stock already owned. Any fraction of a share of Common
Stock required to satisfy such tax obligations shall be disregarded and the amount due shall be paid instead in cash by the Participant. 

14.5 No Assignment of Benefits. No Award or other benefit payable under the Plan shall, except as otherwise specifically
provided by law or permitted by the Committee, be Transferable in any manner, and any attempt to Transfer any such benefit shall be void, and any such benefit shall not in any manner be liable for or subject to the debts, contracts, liabilities,
engagements or torts of any person who shall be entitled to such benefit, nor shall it be subject to attachment or legal process for or against such person. 

14.6 Listing and Other Conditions. 

(a) Unless otherwise determined by the Committee, as long as the Common Stock is listed on a national securities exchange or system sponsored
by a national securities association, the issuance of shares of Common Stock pursuant to an Award shall be conditioned upon such shares being listed on such exchange or system. The Company shall have no obligation to issue such shares unless and
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. 

(b) If at any time counsel to the Company shall be of the opinion that any sale or delivery of shares of Common Stock pursuant to an Option or
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.

 (d) A Participant shall be required to supply the Company with certificates, representations and information that the Company requests and
otherwise cooperate with the Company in obtaining any listing, registration, qualification, exemption, consent or approval the Company deems necessary or appropriate. 

  
 30

to the contrary, as a condition to the receipt of shares of Common Stock pursuant to an Award under the Plan, to the extent required by the Committee, the Participant shall execute and deliver a stockholder’s agreement or such other
documentation that shall set forth certain restrictions on transferability of the shares of Common Stock acquired upon exercise or purchase, and such other terms as the Board or Committee shall from time to time establish. Such stockholder’s
agreement or other documentation shall apply to the Common Stock acquired under the Plan and covered by such stockholder’s agreement or other documentation. The Company may require, as a condition of exercise, the Participant to become a party
to any other existing stockholder agreement (or other agreement). 
 14.8 Governing Law. The Plan and actions taken in
connection herewith shall be governed and construed in accordance with the laws of the State of Delaware (regardless of the law that might otherwise govern under applicable Delaware principles of conflict of laws). 

14.9 Jurisdiction; Waiver of Jury Trial. Any suit, action or proceeding with respect to the Plan or any Award Agreement, or any
judgment entered by any court of competent jurisdiction in respect of any thereof, shall be resolved only in the courts of the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having
jurisdiction of appeals in such courts. In that context, and without limiting the generality of the foregoing, the Company and each Participant shall irrevocably and unconditionally (a) submit in any proceeding relating to the Plan or any Award
Agreement, or for the recognition and enforcement of any judgment in respect thereof (a “Proceeding”), to the exclusive jurisdiction of the courts of the State of Delaware, the court of the United States of America for the District
of Delaware, and appellate courts having jurisdiction of appeals from any of the foregoing, and agree that all claims in respect of any such Proceeding shall be heard and determined in such Delaware State court or, to the extent permitted by law, in
such federal court, (b) consent that any such Proceeding may and shall be brought in such courts and waives any objection that the Company and each Participant may now or thereafter have to the venue or jurisdiction of any such Proceeding in
any such court or that such Proceeding was brought in an inconvenient court and agree not to plead or claim the same, (c) waive all right to trial by jury in any Proceeding (whether based on contract, tort or otherwise) arising out of or
relating to the Plan or any Award Agreement, (d) agree that service of process in any such Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage
prepaid, to such party, in the case of a Participant, at the Participant’s address shown in the books and records of the Company or, in the case of the Company, at the Company’s principal offices, attention General Counsel, and
(e) agree that nothing in the Plan shall affect the right to effect service of process in any other manner permitted by the laws of the State of Delaware. 

14.10 Construction. Wherever any words are used in the Plan in the masculine gender they shall be construed as though they were
also used in the feminine gender in all cases where they would so apply, and wherever words are used herein in the singular form they shall be construed as though they were also used in the plural form in all cases where they would so apply. 

14.11 Other Benefits. No Award granted or paid out under the Plan shall be deemed compensation for purposes of computing
benefits under any retirement plan of the Company or its Affiliates nor affect any benefit under any other benefit plan now or subsequently in effect under which the availability or amount of benefits is related to the level of compensation. 

  
 31 








 14.12 Costs. The Company shall bear all expenses associated with administering this
Plan, including expenses of issuing Common Stock pursuant to Awards hereunder. 
 14.13 No Right to Same Benefits. The
provisions of Awards need not be the same with respect to each Participant, and such Awards to individual Participants need not be the same in subsequent years. 

14.14 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 an
Award. The Committee may also require that the agreement of the transferee to be bound by all of the terms and conditions of the Plan. 

14.15 Section 16(b) of the Exchange Act. All elections and transactions under the Plan by persons subject to
Section 16 of the Exchange Act involving shares of Common Stock are intended to comply with any applicable exemptive condition under Rule 16b-3. The Committee may establish and adopt written administrative guidelines, designed to
facilitate compliance with Section 16(b) of the Exchange Act, as it may deem necessary or proper for the administration and operation of the Plan and the transaction of business thereunder. 

14.16 Section 409A of the Code. The Plan is intended to comply with the applicable requirements of Section 409A of the
Code and shall be limited, construed and interpreted in accordance with such intent. To the extent that any Award is subject to Section 409A of the Code, it shall be paid in a manner that will comply with Section 409A of the Code,
including proposed, temporary or final regulations or any other guidance issued by the Secretary of the Treasury and the Internal Revenue Service with respect thereto. Notwithstanding anything herein to the contrary, any provision in the Plan that
is inconsistent with Section 409A of the Code shall be deemed to be amended to comply with Section 409A of the Code and to the extent such provision cannot be amended to comply therewith, such provision shall be null and void. The Company
shall have no liability to a Participant, or any other party, if an Award that is intended to be exempt from, or compliant with, Section 409A of the Code is not so exempt or compliant or for any action taken by the Committee or the Company and,
in the event that any amount or benefit under the Plan becomes subject to penalties under Section 409A of the Code, responsibility for payment of such penalties shall rest solely with the affected Participants and not with the Company.
Notwithstanding any contrary provision in the Plan or Award Agreement, any payment(s) of “nonqualified deferred compensation” (within the meaning of Section 409A of the Code) that are otherwise required to be made under the Plan to a
“specified employee” (as defined under Section 409A of the Code) as a result of his or her separation from service (other than a payment that is not subject to Section 409A of the Code) shall be delayed for the first six
(6) months following such separation from service (or, if earlier, the date of death of the specified employee) and shall instead be paid (in a manner set forth in the Award Agreement) on the payment date that immediately follows the end of
such six-month period or as soon as administratively practicable thereafter to the extent permitted under Section 409A of the Code. 

  
 32 








 14.17 Successor and Assigns. The Plan shall be binding on all successors and
permitted assigns of a Participant, including, without limitation, the estate of such Participant and the executor, administrator or trustee of such estate. 

14.18 Severability of Provisions. If any provision of the Plan shall be held invalid or unenforceable, such invalidity or
unenforceability shall not affect any other provisions hereof, and the Plan shall be construed and enforced as if such provisions had not been included. 

14.19 Payments to Minors, Etc. Any benefit payable to or for the benefit of a minor, an incompetent person or other person
incapable of receipt thereof shall be deemed paid when paid to such person’s guardian or to the party providing or reasonably appearing to provide for the care of such person, and such payment shall fully discharge the Committee, the Board, the
Company, its Affiliates and their employees, agents and representatives with respect thereto. 
 14.20 Lock-Up Agreements. As
a condition to the grant of an Award, if requested by the Company and the lead underwriter of any public offering of the Common Stock (the “Lead Underwriter”), a Participant shall irrevocably agree not to sell, contract to
sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of, any interest in any Common Stock or any securities convertible into, derivative of, or exchangeable
or exercisable for, or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering) during such period of time following the effective date of a
registration statement of the Company filed under the Securities Act that the Lead Underwriter shall specify (the “Lock-Up Period”). The Participant shall further agree to sign such documents
as may be requested by the Lead Underwriter to effect the foregoing and agree that the Company may impose stop-transfer instructions with respect to Common Stock acquired pursuant to an Award until the end of such
Lock-Up Period. 
 14.21 Headings and Captions. The headings and captions herein are
provided for reference and convenience only, shall not be considered part of the Plan, and shall not be employed in the construction of the Plan. 

14.22 Section 162(m) of the Code. Notwithstanding any other provision of the Plan to the contrary, the provisions of the
Plan requiring compliance with Section 162(m) of the Code shall not apply to Awards granted under the Plan that are not intended to qualify as “performance-based compensation” under Section 162(m) of the Code. 

14.23 Company Recoupment of Awards. A Participant’s rights with respect to any Award hereunder shall in all events be
subject to (i) any right that the Company may have under any Company recoupment policy or other agreement or arrangement with a Participant, or (ii) any right or obligation that the Company may have regarding the clawback of
“incentive-based compensation” under Section 10D of the Exchange Act and any applicable rules and regulations promulgated thereunder from time to time by the U.S. Securities and Exchange Commission.
