 (c) Lapsed Awards. If an Award expires or becomes unexercisable without having been
exercised in full, is surrendered pursuant to an Exchange Program, or, with respect to Restricted Stock, Restricted Stock Units, Performance Units or Performance Shares, is forfeited to or repurchased by the Company due to failure to vest, then the
unpurchased Shares (or for Awards other than Options or 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). With
respect to Stock Appreciation Rights, only Shares actually issued (i.e., the net Shares issued) pursuant to a Stock Appreciation Right will cease to be available under the Plan; all remaining Shares under Stock Appreciation Rights will remain
available for future grant or sale under the Plan (unless the Plan has terminated). Shares that actually have 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 Shares issued pursuant to Awards 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 exercise price of an Award or to satisfy the tax withholding obligations related to 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 and, subject to adjustment as provided in Section 14, 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 pursuant to Sections 3(b) and 3(c). 
 (d) 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. 

  
 -6- 









 (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: 

(i) to determine the Fair Market Value; 

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

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or times when Awards may vest and be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction
or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 

(vi) to institute and determine the terms and conditions of an Exchange Program; 

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

(viii) 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 or for qualifying for favorable tax treatment under applicable foreign laws; 

(ix) to modify or amend each Award (subject to Section 19 of the Plan), including but not limited to the discretionary authority to
extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(b) of the Plan regarding Incentive Stock Options); 

(x) to allow Participants to satisfy tax withholding obligations in such manner as prescribed in Section 15 of the Plan; 

(xi) 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; 
 (xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that otherwise
would be due to such Participant under an Award; and 
 (xiii) to make all other determinations deemed necessary or advisable for
administering the Plan. 

  
 -7- 









 (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, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units 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 one hundred thousand dollars ($100,000), the
portion of the Options falling within such limit will be Incentive Stock Options and the excess 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. 

(b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term
will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. 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 ten percent (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, subject to the following: 
 (1) In the case of an Incentive Stock Option 

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent
(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 one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. 

(B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no
less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

  
 -8- 









 (2) In the case of a Nonstatutory Stock Option, the per Share exercise price will be no less
than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (3) Notwithstanding the foregoing, Options
may be granted with a per Share exercise price of less than one hundred percent (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 of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable
form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws; (4) other Shares, provided that such Shares have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the
Administrator determines in its sole discretion; (5) consideration received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection
with the Plan; (6) by net exercise; (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment. 

(d) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will vest and 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) a notice of exercise (in such form as the Administrator may specify
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 applicable withholding taxes). Full payment may consist of any
consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the
name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other
rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment
will be made for a 

  
 -9- 









 
dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 14 of the Plan. 

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised. 
 (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 the vested portion of 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 vested portion of 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


  
 -10- 









 
exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

7. 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, the Company as escrow agent will hold
Shares of Restricted Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this
Section 7 or the Award Agreement, 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 7, 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 or at such other time as the Administrator may determine. The
Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (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 the Administrator provides otherwise. 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. 

8. Restricted Stock Units. 
 (a)
Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in
an Award Agreement of 

  
 -11- 









 
the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 

(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 settled and the corresponding number of underlying Shares to be paid out to the Participant. The Administrator may set vesting criteria based upon the
achievement of Company-wide, divisional, business unit, or individual goals (including, but not limited to, continued provision of services to the Company or any Parent or Subsidiary of the Company), applicable federal or state securities laws or
any other basis determined by the Administrator in its discretion. 
 (c) Earning Restricted Stock Units. Upon meeting the applicable
vesting criteria, the Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or
waive any vesting criteria that must be met to receive a payout. 
 (d) Form and Timing of Payment. Payment of earned Restricted
Stock Units will be made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or
a combination of both. 
 (e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be
forfeited to the Company. 
 9. 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 Service Provider. 

(c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued pursuant to exercise of a Stock
Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, 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. 
 (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. 

  
 -12- 









 (e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the
Plan will expire ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement, as determined by the Administrator, in its sole discretion. Notwithstanding the foregoing, the rules of
Section 6(d) relating to exercise 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 (the “Payout 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 (which, on the date of
exercise, have an aggregate Fair Market Value equal to the Payout Amount), or in some combination thereof. 
 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 and Performance 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 (including,
without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers.
The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the
Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or
individual goals (including, but not limited to, continued provision of services to the Company or any Parent or Subsidiary of the Company), applicable federal or state securities laws, or any other basis determined by the Administrator in its
discretion. 
 (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 

  
 -13- 









 
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. 

(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. Outside Director Limitations. No Outside Director may be granted, in any Fiscal Year, cash-settled Awards with a grant date fair value (determined
in accordance with U.S. generally accepted accounting principles) of greater than $300,000, increased to $450,000 in the Fiscal Year of his or her initial service as an Outside Director. 

Any Awards granted to an individual while he or she was an Employee, or while he or she was a Consultant but not an Outside Director, will not
count for purposes of the limitations under this Section 11. 
 12. Leaves of Absence/Transfer Between Locations. Unless the Administrator
provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant 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 following the first (1st) day 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. 
 13. 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 

  
 -14- 









 
transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 

14. Adjustments; Dissolution or Liquidation; 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 in Sections 3 and 11(b) 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 previously has not been exercised, an Award will terminate immediately prior to the consummation of such proposed action. 

(c) Change in Control. In the event of a Change in Control, each outstanding Award will be treated as the Administrator determines,
including, without limitation, that (i) Awards may be assumed, or substantially equivalent Awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind
of shares and prices; (ii) upon written notice to a Participant, that the Participant’s Awards will terminate upon or immediately prior to the consummation of such Change in Control; (iii) outstanding Awards will vest and become
exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such Change in Control, and, to the extent the Administrator determines, terminate upon or immediately prior
to the effectiveness of such merger or Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such Award or
realization of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would
have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment), or (B) the replacement of such Award with other rights or property selected
by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this Section 14(c), 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 and Restricted Stock Units will lapse,
and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and 

  
 -15- 









 
all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted 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 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) received in the 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 or its Parent, 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 Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be solely common stock of the
successor corporation or its Parent 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 14(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. 

(d) Outside Director Awards. With respect to Awards granted to an Outside Director, in the event of a Change in Control, then the
Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares which otherwise would not be vested or exercisable, all restrictions on
Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all
other terms and conditions met. 
 15. Tax. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such
earlier time as any tax withholding obligations are due, 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 and any employer tax liability shifted to a Participant with respect to such Award (or exercise thereof). 

  
 -16- 









 (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) (a) paying cash, (b) electing to have the Company withhold otherwise
deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum statutory amount required
to be withheld. The Fair Market Value of the Shares withheld by the Company or delivered to the Company will be determined as of the date that such Shares are withheld or delivered, as applicable. 

(c) Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the
application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A, except as otherwise
determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A and will be construed and interpreted in accordance with such intent, except
as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner
that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A. 

16. No Effect on Employment or Service. Neither the Plan nor any Award will be interpreted as forming an employment or service relationship with the
Company or any Parent or Subsidiary of the Company. Further, 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 or any Parent
or Subsidiary of the Company, nor will they interfere in any way with the Participant’s right or the right of the Company or any Parent or Subsidiary, as applicable, to terminate such relationship at any time, with or without cause, to the
extent permitted by Applicable Laws. 
 17. 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. 

18. Term of Plan. Subject to Section 22 of the Plan, the Plan will become effective upon the later to occur of (a) its adoption by the Board
or (b) the business day immediately prior to the Registration Date. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 19 of the Plan. 

19. Amendment and Termination of the Plan. 

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

  
 -17- 









 (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 materially 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. 

20. 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. 
 21. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction or
to complete or comply with the requirements of any registration or other qualification of the Shares under any state, federal or foreign law or under the rules and regulations of the Securities and Exchange Commission, the stock exchange on which
Shares of the same class are then listed, or any other governmental or regulatory body, which authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the 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, registration, qualification or rule compliance will not have been obtained. 

22. 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 by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.
