property or other rights receivable by the holders of shares of Common Stock upon consummation of such Extraordinary Transaction) and, without further action on the part of the Corporation, the Warrantholder or any other person or entity, the
purchase rights evidenced by this Warrant Agreement shall thereafter represent the right to receive upon exercise pursuant to the terms of Section 2, solely the kind and amount shares or securities, cash, property or other
rights that the Warrantholder would have received if the purchase rights evidenced by this Warrant Agreement (or portion thereof being exercised) had been exercised pursuant to the terms hereof immediately prior to the consummation of such

 3 

 
charges with respect to the issuance thereof. The Corporation hereby covenants and agrees that the Corporation will, at all times through the Expiration Date, reserve and keep available out of
its aggregate authorized but unissued shares of Common Stock, the number of Warrant Shares deliverable upon the exercise of the purchase rights evidenced by this Warrant Agreement. 

5. Adjustment. The number of Warrant Shares purchasable upon the exercise of the purchase rights evidenced by this Warrant Agreement
shall be subject to adjustment from time to time upon the occurrence of certain events, as follows: 
 (a) In case the outstanding shares of
Common Stock shall be subdivided into a greater number of shares or combined into a smaller number of shares, the number of Warrant Shares to be received by the Warrantholder upon exercise of the purchase rights evidenced by this Warrant Agreement
shall be appropriately adjusted such that the proportion of the number of Warrant Shares issuable upon exercise of the purchase rights evidenced by this Warrant Agreement to the total number of outstanding shares of Common Stock immediately prior to
such subdivision or combination is equal to the proportion of the number of Warrant Shares issuable upon exercise of the purchase rights evidenced by this Warrant Agreement to the total number of outstanding shares of Common Stock immediately after
such subdivision or combination. 
 (b) In the case the Corporation shall hereafter declare a dividend or distribution to all holders of the
outstanding shares of Common Stock in shares of Common Stock, the number of Warrant Shares issuable upon exercise of the purchase rights evidenced by this Warrant Agreement shall be increased by dividing such number by a fraction, (i) the
numerator of which shall be the number of shares of Common Stock outstanding at the close of business on such record date, and (ii) the denominator of which shall be the sum of (x) the number of shares of Common Stock outstanding at the
close of business on such record date and (y) the total number of shares of Common Stock constituting such dividend or distribution. If any dividend or distribution of the type described in this Section 5(b) is
declared but not so paid or made, the number of Warrant Shares issuable upon exercise of the purchase rights evidenced by this Warrant Agreement shall again be adjusted to the number of Warrant Shares that would be issuable upon exercise of the
purchase rights evidenced by this Warrant Agreement if such dividend or distribution had not been declared. 
 (c) In the event the
Corporation shall make or issue, or fix a record date for the determination of holders of shares of Common Stock entitled to receive, a dividend or other distribution payable in any securities of the Corporation other than shares of Common Stock
(including, but not limited to, any other class of capital stock or debt securities), then and in each such event the Board shall, to the fullest extent permitted by law, take all lawful actions so that the Warrantholder shall receive upon exercise
of the purchase rights evidenced by this Warrant Agreement, in addition to the number of Warrant Shares receivable upon exercise of the purchase rights evidenced by this Warrant Agreement, the number of such other securities of the Corporation which
the Warrantholder would have received had the purchase rights evidenced by this Warrant Agreement been exercised on the date of such event and had such holder thereafter, during the period from the date of such event to and including the date of
exercise, retained such securities receivable by such holder as aforesaid during such period, giving application to all adjustments called for during such period under this Section 5 as applied to such distributed
securities. 

  
 4 

 (d) The Corporation will not, by amendment of its certificate of incorporation or through any
reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such lawful action as may be necessary or appropriate in order to
protect the rights of the Warrantholder under this Section 5 against impairment. 
 6. Notice of
Adjustments. Whenever an adjustment is required pursuant to Section 5, the Corporation shall, within thirty (30) days of such adjustment, deliver a certificate signed by its chief executive officer or chief
financial officer to the Warrantholder setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and number of Warrant Shares (or other securities)

awards granted under the PLAN that expire or otherwise terminate without having been exercised in full and Shares issued pursuant to awards granted under the PLAN that are forfeited to or repurchased by the Company. There will also be added to the
number of shares that may be awarded and sold under the plan on the first day of each calendar year the lesser of : (i) the number of shares equal to twenty percent (20%) of the difference between the number of shares of Common Stock issued and

 (b) Lapsed Awards. If an Award expires or becomes unexercisable without having been
exercised in full, or, with respect to Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units, is forfeited to or repurchased by the Company, the unpurchased Shares (or for Awards other than Options and Stock Appreciation
Rights, the forfeited or repurchased Shares) which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). Upon exercise of a Stock Appreciation Right settled in Shares, the net number of
Shares actually issued pursuant to the Award so exercised will cease to be available under the Plan. Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future
distribution under the Plan; provided, however, that if unvested Shares of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become
available for future grant under the Plan. Shares used to pay the tax and exercise price of an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such
cash payment will not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing provisions of this Section 3(b), subject to adjustment provided in Section 13, the maximum number of Shares
that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code, any Shares that become available for issuance under
the Plan under this Section 3(b). 
 (c) Share Reserve. The Company, during the term of this Plan, will at all times reserve and
keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan. 
 4. Administration of the Plan.

 (a) Procedure. 
 (i)
Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted
hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be administered by a Committee of two (2) or more “outside directors” within the meaning of
Section 162(m) of the Code. 
 (iii) Rule 16b-3. To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

 (iv) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a
Committee, which committee will be constituted to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to the
provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion: 

  
 -5- 

 (i) to determine the Fair Market Value; 

(ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder; 

(iv) to determine the terms and conditions of any, and with the approval of the Company’s stockholders, to institute an Exchange Program;

 (v) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(vi) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws; 
 (vii) to modify or amend
each Award (subject to Section 18(c) of the Plan); 
 (viii) to authorize any person to execute on behalf of the Company any instrument
required to effect the grant of an Award previously granted by the Administrator; 
 (ix) to allow a Participant to defer the receipt of the
payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award pursuant to such procedures as the Administrator may determine; and 

(x) to make all other determinations deemed necessary or advisable for administering the Plan. 

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations, and interpretations
will be final and binding on all Participants and any other holders of Awards. 
 5. Eligibility. Nonstatutory Stock Options,
Restricted Stock, Restricted Stock Units, Stock Appreciation Rights, Performance Units, Performance Shares, and such other cash or stock awards as the Administrator determines may be granted to Service Providers. Incentive Stock Options may be
granted only to Employees. 
 6. Stock Options. 

(a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000 (U.S.), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options will be taken into account in the order in
which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 

  
 -6- 

 (b) Term of Option. The Administrator will determine the term of each Option in its sole
discretion; provided, however, that the term will be no more than ten (10) years from the date of grant thereof. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted,
owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter
term as may be provided in the Award Agreement. 
 (c) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by
the Administrator, but will be no less than 100% of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock
representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. Notwithstanding the
foregoing provisions of this Section 6(c), Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with,
Section 424(a) of the Code. 
 (ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will
fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 

(iii) Form of Consideration. The Administrator will determine the acceptable form(s) of consideration for exercising an Option,
including the method of payment, to the extent permitted by Applicable Laws. 
 (d) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the
Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator specifies from
time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with any applicable withholding taxes). No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 

  
 -7- 

 (ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a
Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the
extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain
exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will
revert to the Plan. 
 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the
Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration
of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless otherwise
provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does
not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the Participant’s
death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of the term of such Option as set forth in
the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the
Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent
and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at the time of death
Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate,
and the Shares covered by such Option will revert to the Plan. 
 (v) Other Termination. A Participant’s Award Agreement may
also provide that if the exercise of the Option following the termination of Participant’s status as a Service Provider (other than upon the Participant’s death or Disability) would result in liability under Section 16(b), then the
Option will terminate on the earlier of (A) the expiration of the term of the Option set forth in the Award Agreement, or (B) the 10th day after the last date on which such exercise would result in such liability under Section 16(b).
Finally, a Participant’s Award Agreement may also provide that if the exercise of the Option following the termination of the Participant’s status as a Service Provider (other than upon the Participant’s death or Disability)

  
 -8- 

 
would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act, then the Option will terminate on the earlier of
(A) the expiration of the term of the Option, or (B) the expiration of a period of three (3) months after the termination of the Participant’s status as a Service Provider during which the exercise of the Option would not be in
violation of such registration requirements. 
 7. Stock Appreciation Rights. 

(a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to
Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 
 (b) Number of
Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted to any Participant. 

(c) Exercise Price and Other Terms. The Administrator, subject to the provisions of the Plan, will have complete discretion to determine
the terms and conditions of Stock Appreciation Rights granted under the Plan, provided, however, that the exercise price will be not less than 100% of the Fair Market Value of a Share on the date of grant. 

(d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify
the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by
the Administrator, in its sole discretion, and set forth in the Award Agreement; provided, however, that the term will be no more than ten (10) years from the date of grant thereof. Notwithstanding the foregoing, the rules of Section 6(d)
also will apply to Stock Appreciation Rights. 
 (f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation
Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference
between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect to
which the Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in
cash, in Shares of equivalent value, or in some combination thereof. 

  
 -9- 

 8. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time,
may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of
Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, Shares of Restricted Stock will be held by the Company as
escrow agent until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this Section 8,
Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as
it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this Section 8, Shares of
Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction. The Administrator, in its discretion, may accelerate the time at which
any restrictions will lapse or be removed, upon such terms and conditions as the administrator may determine. 
 (f) Voting Rights.
During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be
entitled to receive all dividends and other distributions paid with respect to such Shares unless otherwise provided in the Award Agreement. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same
restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 
 (h) Return
of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 

9. Restricted Stock Units. 

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. Each Restricted
Stock Unit grant will be evidenced by an Award Agreement that will specify such other terms and conditions as the Administrator, in its sole discretion, will determine, including all terms, conditions, and restrictions related to the grant, the
number of Restricted Stock Units and the form of payout, which, subject to Section 9(d), may be left to the discretion of the Administrator. 

  
 -10- 

 (b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its
discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. After the grant of Restricted Stock Units, the Administrator, in its sole
discretion, may reduce or waive any restrictions for such Restricted Stock Units. Each Award of Restricted Stock Units will be evidenced by an Award Agreement that will specify the vesting criteria, and such other terms and conditions as the
Administrator, in its sole discretion will determine. 
 (c) Earning Restricted Stock Units. Upon meeting the applicable vesting
criteria, the Participant will be entitled to receive a payout as specified in the Award Agreement. 
 (d) Form and Timing of Payment.
Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) set forth in the Award Agreement. The Administrator, in its sole discretion, may pay earned Restricted Stock Units in cash, Shares, or a combination
thereof. Shares represented by Restricted Stock Units that are fully paid in cash again will be available for grant under the Plan. 
 (e)
Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company. 

10. Performance Units and Performance Shares. 

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from
time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units/Shares granted to each Participant. 

(b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or
before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions. The
Administrator may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment), or any other basis determined by the Administrator in its discretion. The
time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” 

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will
be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting
provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share. 

  
 -11- 

 (e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance
Units/Shares will be made as soon as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate
Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 

(f) Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance
Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 
 11. Leaves of Absence. Unless
the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Service Provider will not cease to be an Employee in the case of (i) any leave of absence approved by the Company,
or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave
is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months and one (1) day following the commencement of such leave any Incentive Stock
Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 

12. Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award
transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 
 13. Adjustments;
Dissolution or Liquidation; Merger or Change in Control. 
 (a) Adjustments. In the event that any dividend or other distribution
(whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order
to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares
covered by each outstanding Award, and the numerical Share limits set forth in Section 3 of the Plan. 
 (b) Dissolution or
Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been
previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 

  
 -12- 

 (c) Change in Control. In the event of a merger or Change in Control, each outstanding
Award will be treated as the Administrator determines, including, without limitation, that each Award will be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation
(the “Successor Corporation”). The Administrator will not be required to treat all Awards similarly in the transaction. 

In the event that the Successor Corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right
to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock will lapse, and, with respect to Restricted
Stock Units, Performance Shares and Performance Units, all performance goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not
assumed or substituted for in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be fully vested and exercisable for a period of time
determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the Award confers the right
to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) or, in the case of a Stock Appreciation Right upon the exercise of which
the Administrator determines to pay cash or a Performance Share or Performance Unit which the Administrator can determine to pay in cash, the fair market value of the consideration received in the merger or Change in Control by holders of Common
Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such
consideration received in the Change in Control is not solely common stock of the Successor Corporation, the Administrator may, with the consent of the Successor Corporation, provide for the consideration to be received upon the exercise of an
Option or Stock Appreciation Right or upon the payout of a Performance Share or Performance Unit, for each Share subject to such Award (or in the case of Performance Units, the number of implied shares determined by dividing the value of the
Performance Units by the per share consideration received by holders of Common Stock in the Change in Control), to be solely common stock of the Successor Corporation equal in fair market value to the per share consideration received by holders of
Common Stock in the Change in Control. 
 Notwithstanding anything in this Section 13(c) to the contrary, an Award that vests, is
earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s
consent; provided, however, a modification to such performance goals only to reflect the Successor Corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 

14. Tax Withholding 
 (a)
Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof). 

  
 -13- 

 (b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to
such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise
deliverable cash or Shares having a Fair Market Value equal to the minimum amount required to be withheld, (iii) delivering to the Company already-owned Shares having a Fair Market Value equal to the amount required to be withheld, or
(iv) selling a sufficient number of Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be
withheld. The amount of the withholding requirement will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state or
local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined. The Fair Market Value of the Shares to be withheld or delivered will be determined as of
the date that the taxes are required to be withheld. 
 15. No Effect on Employment or Service. Neither the Plan nor any Award will
confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate
such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 16. Date of Grant. The date of
grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each
Participant within a reasonable time after the date of such grant. 
 17. Term of Plan. Subject to Section 21 of the Plan,
the Plan will become effective upon its adoption by the Board. It will continue in effect for a term of ten (10) years unless terminated earlier under Section 18 of the Plan. 

18. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to
comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension, or termination of the
Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect
the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

  
 -14- 

 19. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance
and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to
represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation
is required. 
 20. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to
which such requisite authority will not have been obtained. 
 21. Stockholder Approval. The Plan will be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

 II. STOCK OPTION AGREEMENT 

A. Grant of Option.  
 The
Plan Administrator of the Company hereby grants to the Optionee named in the Notice of Stock Option Grant in Part I of this Agreement an Option to purchase the number of Shares, as set forth in the Notice of Stock Option Grant, at the exercise price
per share set forth in the Notice of Stock Option Grant (the “Exercise Price”), subject to the terms and conditions of the Plan, which is incorporated herein by reference. In the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the
Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this Option is intended to be an Incentive Stock Option, to
the extent that it exceeds the $100,000 rule of Code Section 422(d), it shall be treated as a Nonstatutory Stock Option (“NSO”). 

B. Exercise of Option. 
 1.
Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and the applicable provisions of the Plan and this Option Agreement. 

2. Method of Exercise. This Option is exercisable by delivery of the Company’s stock option exercise notice in effect at the time
of exercise (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and
agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice shall be completed by the Optionee and delivered to the Chief Financial Officer of the Company. The Exercise Notice shall be accompanied
by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price. 

No Shares shall be issued pursuant to the exercise of this Option unless such issuance and exercise complies with Applicable Laws. Assuming
such compliance, for income tax purposes the Exercised Shares shall be considered transferred to the Optionee on the date the Option is exercised with respect to such Exercised Shares. 

  
 2 

 C. Method of Payment. 

Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee: 

1. Cash; 
 2. Check; 

3. Consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan; or 

4. Surrender of other Shares which (i) in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares. 

D. Transferability of Option. 

This Option may be transferred by the Optionee only with the written consent of the Plan Administrator. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 E. Term of Option.

 This Option may be exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option Agreement. 
 F. Tax Consequences.  

Some of the federal tax consequences relating to this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISOR BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 

G. Exercising the Option. 

1. Nonstatutory Stock Option. The Optionee may incur regular federal income tax liability upon exercise of a NSO. The Optionee will be
treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Exercised Shares on the date of exercise over their aggregate Exercise Price. If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his or her compensation or collect from Optionee and pay to the applicable taxing authorities an amount in cash equal to a percentage of this compensation income at the
time of exercise, and may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise.

 2. Incentive Stock Option. If this Option qualifies as an ISO, the Optionee will have no
regular federal income tax liability upon its exercise, although the excess, if any, of the Fair Market Value of the Exercised Shares on the date of exercise over their aggregate Exercise Price will be treated as an adjustment to alternative minimum
taxable income for federal tax purposes and may subject the Optionee to alternative minimum tax in the year of exercise. In the event that the Optionee ceases to be an Employee but remains a Service Provider, any Incentive Stock Option of the
Optionee that remains unexercised shall cease to qualify as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option on the date three (3) months and one (1) day following such change of status. 

3. Disposition of Shares. 

1. NSO. If the Optionee holds NSO Shares for at least one year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes. 
 2. ISO. If the Optionee holds ISO Shares for at least one year after
exercise and two years after the Grant Date, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. If the Optionee disposes of ISO Shares within one year after exercise or two years
after the Grant Date, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the excess, if any, of the lesser of (A) the difference between the Fair Market Value of the
Shares acquired on the date of exercise and the aggregate Exercise Price, or (B) the difference between the sale price of such Shares and the aggregate Exercise Price. Any additional gain will be taxed as capital gain, short-term or long-term
depending on the period that the ISO Shares were held. 
 3. Notice of Disqualifying Disposition of ISO Shares. If the Optionee sells
or otherwise disposes of any of the Shares acquired pursuant to an ISO on or before the later of (i) two years after the Grant Date, or (ii) one year after the exercise date, the Optionee shall immediately notify the Company in writing of
such disposition. The Optionee agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized from such early disposition of ISO Shares by payment in cash or out of the current earnings paid to
the Optionee. 
 H. Entire Agreement; Governing Law. 

The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to
the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means
of a writing signed by the Company and Optionee. This agreement is governed by the internal substantive laws, but not the choice of law rules, of Texas.

 I. NO GUARANTEE OF CONTINUED SERVICE. 

OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A
SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND
THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE’S RIGHT OR THE
COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 J.
FLUCTUATIONS IN STOCK PRICE 
 OPTIONEE ACKNOWLEDGES AND AGREES THAT THE EXERCISE PRICE OF THE OPTION GRANTED BY THE COMPANY
AND REFERRED TO HEREIN IS THE FAIR MARKET VALUE OF THE COMPANY’S COMMON STOCK ON THE DATE THE OPTION WAS GRANTED AS DETERMINED BY THE PLAN ADMINISTRATOR. THE FAIR MARKET VALUE OF THE COMPANY’S COMMON STOCK IS SUBJECT TO MANY FACTORS,
INCLUDING THE ANNOUNCEMENT OF NEW PRODUCTS OR SERVICES BY THE COMPANY OR ITS COMPETITORS, VARIATIONS IN THE COMPANY’S OR ITS COMPETITORS’ RESULTS OF OPERATIONS, FAILURE TO ACHIEVE OPERATING RESULTS, GENERAL MARKET CONDITIONS AND OTHER
FACTORS, INCLUDING FACTORS UNRELATED TO OUR OPERATING PERFORMANCE OR THE OPERATING PERFORMANCE OF OUR COMPETITORS. THEREFORE, THE COMPANY CANNOT GUARANTEE THAT THE OPTION WILL HAVE ANY VALUE IN THE FUTURE. 

By your signature and the signature of the Company’s representative below, you and the Company agree that this Option is granted under
and governed by the terms and conditions of the Plan and this Option Agreement. You and the Company agree that this Option is not valid and enforceable until both parties hereto have executed this Option Agreement. Optionee has reviewed the
Plan and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option Agreement and fully understands all provisions of the Plan and Option Agreement. Optionee hereby agrees to accept
as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions relating to the Plan and Option Agreement. Optionee further agrees to notify the Company upon any change in the residence address indicated
below.
